Inexperience Diagnosing Syphilis Adding to Higher Rates

With rates of syphilis rising quickly in the United States and elsewhere, clinicians are having to up their game when it comes to diagnosing and treating an infection that they may not be paying enough attention to.

More than 200,000 cases of syphilis were reported in the United States in 2022, which is the highest number since 1950 and is a 17.3% increase over 2021, according to the latest figures from the Centers for Disease Control and Prevention (CDC). The rate of infection has increased almost every year since a historic low in 2001.

And the trend is not limited to the United States. Last year, the infection rate in the United Kingdom hit a 50-year high, said David Mabey, BCh, DM, from the London School of Hygiene and Tropical Medicine. Syphilis and other sexually transmitted infections are also a major problem in low- and middle-income countries, he added, although good data are not always available.

Many of today’s healthcare professionals have little experience with the disease, shared Ina Park, MD, a sexually transmitted infections specialist at the University of California at San Francisco. “An entire generation of physicians — including myself — did not see any cases until we were well out of our training,” Dr. Park reported. “We’re really playing catch-up.”
 

A Centuries-Old Ailment

Dr. Park offered some advice on the challenges of diagnosing what can be an elusive infection at the Conference on Retroviruses and Opportunistic Infections (CROI) 2024 Annual Meeting in Denver. That advice boiled down to one simple rule: “Test, test, test.”

Because syphilis can mimic so many other conditions and can have long periods of latency, it can be easily missed or even misdiagnosed by experienced physicians, said Dr. Park. Clinicians need to keep it front of mind and have a lower threshold for testing, even if there are no obvious symptoms.

Following the CDC’s new recommendations for syphilis screening will help, she noted; every sexually active patient aged between 15 and 44 years who lives in a county with a syphilis infection rate of 4.6 per 100,000 people or higher should get the test. And clinicians should remain vigilant, even in areas with a lower prevalence. “If you can’t account for new symptoms in a sexually active patient, order a test,” said Dr. Park.
 

Complicated Cases

The lack of experience with syphilis affects not just diagnosis but also treatment, particularly for complex cases, said Khalil Ghanem, MD, PhD, from the Johns Hopkins University School of Medicine in Baltimore. “When you don’t have to deal with something for a while, you forget how to deal with it,” he added.

At CROI, Dr. Ghanem offered suggestions for how to navigate complicated cases of ocular syphilis, otic syphilis, and neurosyphilis, and how to interpret test results when a patient’s antigen titers are being “unruly.”

With potential ocular or otic syphilis, you shouldn’t wait for a specialist like an ophthalmologist to weigh in but instead refer the patient directly to the emergency department because of the risk that the symptoms may become irreversible and result in permanent blindness or deafness. “You don’t want to dilly-dally with those conditions,” Dr. Ghanem said.

Closely monitoring a patient’s rapid plasma regain and venereal disease research laboratory antigen levels is the only way to manage syphilis and to determine whether the infection is responding to treatment, he noted, but sometimes those titers “don’t do what you think they should be doing” and fail to decline or even go up after treatment.

“You don’t know if they went up because the patient was re-infected, or they developed neurosyphilis, or there was a problem at the lab,” he said. “It can be challenging to interpret.”

To decipher confusing test results, Dr. Ghanem recommended getting a detailed history to understand whether a patient is at risk for reinfection, whether there are signs of neurosyphilis or other complications, whether pregnancy is possible, and so on. “Based on the answers, you can determine what the most rational approach to treatment would be,” he shared.
 

 

 

Drug Shortages

Efforts to get the infection under control have become more complicated. Last summer, Pfizer announced that it had run out of penicillin G benzathine (Bicillin), an injectable, long-acting drug that is one of the main treatments for syphilis and the only one that can be given to pregnant people. Supplies for children ran out at the end of June 2023, and supplies for adults were gone by the end of September.

Because Pfizer is the only company that manufactures penicillin G benzathine, there is no one to pick up the slack in the short-term, so the shortage is expected to continue until at least the middle of 2024.

In response, the US Food and Drug Administration has temporarily allowed the use of benzylpenicillin benzathine (Extencilline), a French formulation that has not been approved in the United States, until supplies of penicillin G benzathine are stabilized.

The shortage has shone a spotlight on the important issue of a lack of alternatives for the treatment of syphilis during pregnancy, which increases the risk for congenital syphilis. “Hopefully, this pushes the National Institutes of Health and others to step up their game on studies for alternative drugs for use in pregnancy,” Dr. Ghanem said.

Multimodal Treatment Found Effective for Overactive Bladder

Article Type
Changed
Mon, 03/18/2024 - 09:34

 

TOPLINE:

A new study published in JAMA Network Open showed that an intervention including cognitive behavioral therapy improved the quality of life for women with overactive bladder (OAB).

METHODOLOGY:

  • A total of 79 women with moderate to severe OAB were randomized to the control group or the intervention, which was composed of four 30-minute sessions using strategies including cognitive behavioral therapy (CBT).
  • The first and second sessions provided education on OAB and CBT, lifestyle modifications such as limiting coffee intake, pelvic floor muscle training, and introduced exposure training.
  • The third and fourth sessions continued exposure and pelvic floor muscle training and education on relapse prevention.
  • Researchers assessed outcomes using the health-related quality of life (HRQOL), in which participants answered questions regarding their degree of distress, emotions, and physical and social limitations related to OAB symptoms.

TAKEAWAY:

  • Participants who received the intervention on average improved in their HRQOL score by 12.6 points higher than those in the control group (usual care) from baseline to week 13 (between-group difference estimate, 12.6 [95% CI, 6.6-18.6] points; P < .001).
  • The average age of participants was 63.5 years, and more than 87% of women in each group had moderate OAB.
  • Patient-reported improvement and satisfaction scores were also more improved in the intervention group than in the control group; most participants in both groups had no change in the pharmacotherapy during the trial.

IN PRACTICE:

Urologists and other primary care clinicians who treat women with OAB may consider a multicomponent intervention that includes cognitive components and exposure-based bladder training or could refer to a cognitive behavioral therapist or pelvic floor physical therapist experienced in these techniques.

SOURCE:

Satoshi Funada, MD, PhD, and Takashi Kobayashi, MD, PhD, both with the Department of Urology at Kyoto University Graduate School of Medicine in Kyoto, Japan, are the corresponding authors. The study was published online in JAMA Network Open.

LIMITATIONS:

The trial was open label, and the use of a waiting list control group is known to produce greater differences between the two groups. The trial included patients both taking and not taking medication for OAB. The sample size was also relatively small, and the intervention was performed by a single clinician, possibly limiting the generalizability of results.

DISCLOSURES:

The study was funded by the Japan Society for the Promotion of Science (JSPS). Various study authors reported receiving grants from the Pfizer Health Research Foundation, AstraZeneca, and JSPS. Other study authors reported receiving personal fees from Eisai, Sawai Pharmaceutical, Statcom, and others. One author reported pending patents for intellectual properties for the Kokoro app licensed to Mitsubishi Tanabe Pharma.

High Cesarean Rates Persist in Obesity Despite Standardized Protocols

Article Type
Changed
Fri, 03/15/2024 - 11:34

— Implementation of a standardized induction of labor protocol had no significant effect on the rates of cesarean delivery in patients with obesity, based on data from more than 5000 individuals.

Previous research has shown that the risk for cesarean delivery increases by 5% with each 1-kg/m2 increase in body mass index (BMI) among nulliparous patients, said Melissa Riegel, MD, of the University of Pennsylvania, Philadelphia, in a presentation at the meeting sponsored by the Society for Maternal-Fetal Medicine. (abstract 82).

Research on the relationship between obesity and higher cesarean delivery rates “has been clouded by the inability to reduce variation in care,” Dr. Riegel said at the meeting sponsored by the Society for Maternal Fetal Medicine. Failed induction of labor (IOL) is a leading indicator for cesarean delivery, and cesarean delivery is 80% more likely in patients with obesity undergoing IOL than in normal-weight patients, Dr. Riegel said.

Possible explanations for these differences include provider factors such as variability in care management, conscious and unconscious biases, or physiologic differences in patients with obesity such as elevated hormones, differences in the labor curve, and higher doses of oxytocin and prostaglandins, Dr. Riegel said.

Dr. Riegel and colleagues hypothesized that differences in cesarean delivery rates would persist despite a standardized labor induction protocol, thereby supporting the effects of factors other than variations in care on increased cesarean delivery risk after IOL in patients with obesity.

The researchers reviewed data from two sites comparing 2-year periods before and after implementation of an IOL protocol from 2018 to 2022. The study population included nulliparous women with singleton pregnancies at term who underwent IOL with intact membranes and unfavorable cervices, and had a BMI of at least 30 kg/m2 at delivery. The preimplementation group (PRE) included 2480 individuals and the postimplementation group (POST) included 2651 individuals. Patients were divided into weight classes based on BMI: 30-34.9; 35-39.9; ≥40.

The standardized protocol consisted of active labor management with cervical exams, with an amniotomy by the time of the first exam with 4 cm or greater cervical dilation, and further intervention with medication such as oxytocin or an intrauterine pressure catheter if no cervical change was noted after 2 hours.

In a multivariate analysis, the overall cesarean delivery rate was 24.9% before the protocol implementation and 26.0% in the postimplementation group. There were no differences in the risk of cesarean delivery in any obesity class from the PRE to POST period.

In addition, no significant differences appeared in the secondary outcomes of duration of labor, maternal morbidity, or neonatal morbidity, Dr. Riegel said. Nonreassuring fetal heart rate tracing was the most common reason for cesarean delivery across all obesity classes and the PRE and POST groups.

Study limitations included the use of data from only two sites, but the results were strengthened by the large sample size, said Dr. Reigel. The results indicate that reducing variation in IOL management had no significant effect on the relationship between obesity and cesarean delivery and support underlying physiologic explanations, she said.
 

 

 

Making the Case for Physiology

“By standardizing induction practices, we were able to minimize differences in care and better answer why the increased cesarean delivery rate exists in this patient population,” Dr. Riegel said in an interview. The findings were in line with the primary hypothesis that standardized induction would not affect cesarean delivery rates in patients with obesity, she said. Instead, the findings support potential physiologic differences as “the driving force behind this relationship,” she added.

Looking ahead, “There is a role for translational work to investigate the specific biological changes in patients with obesity that might contribute to an increased risk of cesarean delivery and there is also a role for investigating the effectiveness of different labor induction interventions specifically in patients with obesity,” Dr. Riegel said.
 

Different Induction Protocols Needed for Obese Patients?

“Given that severe maternal morbidity and mortality are continuing to increase in the United States, this study is critical, as we know that both cesarean delivery and obesity are driving factors in increasing maternal morbidity,” said Marissa Platner, MD, a maternal-fetal medicine specialist at Emory University, Atlanta, Georgia, in an interview.

However, the novel takeaway message from the current study is that patients with obesity were more likely to require cesarean delivery even with a protocol in which variation in labor induction techniques are minimized, said Dr. Platner, who was not involved in the study. “This leads to the question of [whether] we should have different standards or protocols for our patients with obesity, as well as a need for clear counseling for these patients early on in pregnancy,” she said.

As for further research, “It would be interesting to see if the risk of cesarean delivery changed based on class of obesity, and the primary drivers of cesarean delivery in this study,” Dr. Platner said. “Additionally, it would be helpful to know how much pitocin was needed for patients, based on their BMI category, to achieve successful vaginal delivery,” she noted.

The study was supported by a grant from the Eunice Kennedy Shriver National Institute of Child Health and Development. The researchers had no financial conflicts to disclose. Dr. Platner had no financial conflicts to disclose.

However, the novel takeaway message from the current study is that patients with obesity were more likely to require cesarean delivery even with a protocol in which variation in labor induction techniques are minimized, said Dr. Platner, who was not involved in the study. “This leads to the question of [whether] we should have different standards or protocols for our patients with obesity, as well as a need for clear counseling for these patients early on in pregnancy,” she said.

As for further research, “It would be interesting to see if the risk of cesarean delivery changed based on class of obesity, and the primary drivers of cesarean delivery in this study,” Dr. Platner said. “Additionally, it would be helpful to know how much pitocin was needed for patients, based on their BMI category, to achieve successful vaginal delivery,” she noted.

The study was supported by a grant from the Eunice Kennedy Shriver National Institute of Child Health and Development. The researchers had no financial conflicts to disclose. Dr. Platner had no financial conflicts to disclose.

— Implementation of a standardized induction of labor protocol had no significant effect on the rates of cesarean delivery in patients with obesity, based on data from more than 5000 individuals.

Previous research has shown that the risk for cesarean delivery increases by 5% with each 1-kg/m2 increase in body mass index (BMI) among nulliparous patients, said Melissa Riegel, MD, of the University of Pennsylvania, Philadelphia, in a presentation at the meeting sponsored by the Society for Maternal-Fetal Medicine. (abstract 82).

Research on the relationship between obesity and higher cesarean delivery rates “has been clouded by the inability to reduce variation in care,” Dr. Riegel said at the meeting sponsored by the Society for Maternal Fetal Medicine. Failed induction of labor (IOL) is a leading indicator for cesarean delivery, and cesarean delivery is 80% more likely in patients with obesity undergoing IOL than in normal-weight patients, Dr. Riegel said.

Possible explanations for these differences include provider factors such as variability in care management, conscious and unconscious biases, or physiologic differences in patients with obesity such as elevated hormones, differences in the labor curve, and higher doses of oxytocin and prostaglandins, Dr. Riegel said.

Dr. Riegel and colleagues hypothesized that differences in cesarean delivery rates would persist despite a standardized labor induction protocol, thereby supporting the effects of factors other than variations in care on increased cesarean delivery risk after IOL in patients with obesity.

The researchers reviewed data from two sites comparing 2-year periods before and after implementation of an IOL protocol from 2018 to 2022. The study population included nulliparous women with singleton pregnancies at term who underwent IOL with intact membranes and unfavorable cervices, and had a BMI of at least 30 kg/m2 at delivery. The preimplementation group (PRE) included 2480 individuals and the postimplementation group (POST) included 2651 individuals. Patients were divided into weight classes based on BMI: 30-34.9; 35-39.9; ≥40.

The standardized protocol consisted of active labor management with cervical exams, with an amniotomy by the time of the first exam with 4 cm or greater cervical dilation, and further intervention with medication such as oxytocin or an intrauterine pressure catheter if no cervical change was noted after 2 hours.

In a multivariate analysis, the overall cesarean delivery rate was 24.9% before the protocol implementation and 26.0% in the postimplementation group. There were no differences in the risk of cesarean delivery in any obesity class from the PRE to POST period.

In addition, no significant differences appeared in the secondary outcomes of duration of labor, maternal morbidity, or neonatal morbidity, Dr. Riegel said. Nonreassuring fetal heart rate tracing was the most common reason for cesarean delivery across all obesity classes and the PRE and POST groups.

Study limitations included the use of data from only two sites, but the results were strengthened by the large sample size, said Dr. Reigel. The results indicate that reducing variation in IOL management had no significant effect on the relationship between obesity and cesarean delivery and support underlying physiologic explanations, she said.
 

 

 

Making the Case for Physiology

“By standardizing induction practices, we were able to minimize differences in care and better answer why the increased cesarean delivery rate exists in this patient population,” Dr. Riegel said in an interview. The findings were in line with the primary hypothesis that standardized induction would not affect cesarean delivery rates in patients with obesity, she said. Instead, the findings support potential physiologic differences as “the driving force behind this relationship,” she added.

Looking ahead, “There is a role for translational work to investigate the specific biological changes in patients with obesity that might contribute to an increased risk of cesarean delivery and there is also a role for investigating the effectiveness of different labor induction interventions specifically in patients with obesity,” Dr. Riegel said.

Vitamin D Supplements May Be a Double-Edged Sword

This transcript has been edited for clarity.

Welcome to Impact Factor, your weekly dose of commentary on a new medical study. I’m Dr F. Perry Wilson of the Yale School of Medicine.

Imagine, if you will, the great Cathedral of Our Lady of Correlation. You walk through the majestic oak doors depicting the link between ice cream sales and shark attacks, past the rose window depicting the cardiovascular benefits of red wine, and down the aisles frescoed in dramatic images showing how Facebook usage is associated with less life satisfaction. And then you reach the altar, the holy of holies where, emblazoned in shimmering pyrite, you see the patron saint of this church: vitamin D.

Yes, if you’ve watched this space, then you know that I have little truck with the wildly popular supplement. In all of clinical research, I believe that there is no molecule with stronger data for correlation and weaker data for causation.

Low serum vitamin D levels have been linked to higher risks for heart disease, cancer, falls, COVID, dementia, C diff, and others. And yet, when we do randomized trials of vitamin D supplementation — the thing that can prove that the low level was causally linked to the outcome of interest — we get negative results.

F. Perry Wilson, MD, MSCE


Trials aren’t perfect, of course, and we’ll talk in a moment about a big one that had some issues. But we are at a point where we need to either be vitamin D apologists, saying, “Forget what those lying RCTs tell you and buy this supplement” — an $800 million-a-year industry, by the way — or conclude that vitamin D levels are a convenient marker of various lifestyle factors that are associated with better outcomes: markers of exercise, getting outside, eating a varied diet.

Or perhaps vitamin D supplements have real effects. It’s just that the beneficial effects are matched by the harmful ones. Stay tuned.

The Women’s Health Initiative remains among the largest randomized trials of vitamin D and calcium supplementation ever conducted — and a major contributor to the negative outcomes of vitamin D trials.

But if you dig into the inclusion and exclusion criteria for this trial, you’ll find that individuals were allowed to continue taking vitamins and supplements while they were in the trial, regardless of their randomization status. In fact, the majority took supplements at baseline, and more took supplements over time.

Annals of Internal Medicine


That means, of course, that people in the placebo group, who were getting sugar pills instead of vitamin D and calcium, may have been taking vitamin D and calcium on the side. That would certainly bias the results of the trial toward the null, which is what the primary analyses showed. To wit, the original analysis of the Women’s Health Initiative trial showed no effect of randomization to vitamin D supplementation on improving cancer or cardiovascular outcomes.

But the Women’s Health Initiative trial started 30 years ago. Today, with the benefit of decades of follow-up, we can re-investigate — and perhaps re-litigate — those findings, courtesy of this study, “Long-Term Effect of Randomization to Calcium and Vitamin D Supplementation on Health in Older Women” appearing in Annals of Internal Medicine.

Dr Cynthia Thomson, of the Mel and Enid Zuckerman College of Public Health at the University of Arizona, and colleagues led this updated analysis focused on two findings that had been hinted at, but not statistically confirmed, in other vitamin D studies: a potential for the supplement to reduce the risk for cancer, and a potential for it to increase the risk for heart disease.

The randomized trial itself only lasted 7 years. What we are seeing in this analysis of 36,282 women is outcomes that happened at any time from randomization to the end of 2023 — around 20 years after the randomization to supplementation stopped. But, the researchers would argue, that’s probably okay. Cancer and heart disease take time to develop; we see lung cancer long after people stop smoking. So a history of consistent vitamin D supplementation may indeed be protective — or harmful.

Here are the top-line results. Those randomized to vitamin D and calcium supplementation had a 7% reduction in the rate of death from cancer, driven primarily by a reduction in colorectal cancer. This was statistically significant. Also statistically significant? Those randomized to supplementation had a 6% increase in the rate of death from cardiovascular disease. Put those findings together and what do you get? Stone-cold nothing, in terms of overall mortality.

Annals of Internal Medicine


Okay, you say, but what about all that supplementation that was happening outside of the context of the trial, biasing our results toward the null?

The researchers finally clue us in.

First of all, I’ll tell you that, yes, people who were supplementing outside of the trial had higher baseline vitamin D levels — a median of 54.5 nmol/L vs 32.8 nmol/L. This may be because they were supplementing with vitamin D, but it could also be because people who take supplements tend to do other healthy things — another correlation to add to the great cathedral.

To get a better view of the real effects of randomization, the authors restricted the analysis to just those who did not use outside supplements. If vitamin D supplements help, then these are the people they should help. This group had about a 11% reduction in the incidence of cancer — statistically significant — and a 7% reduction in cancer mortality that did not meet the bar for statistical significance.

Annals of Internal Medicine


There was no increase in cardiovascular disease among this group. But this small effect on cancer was nowhere near enough to significantly reduce the rate of all-cause mortality.

Annals of Internal Medicine


Among those using supplements, vitamin D supplementation didn’t really move the needle on any outcome.

I know what you’re thinking: How many of these women were vitamin D deficient when we got started? These results may simply be telling us that people who have normal vitamin D levels are fine to go without supplementation.

Nearly three fourths of women who were not taking supplements entered the trial with vitamin D levels below the 50 nmol/L cutoff that the authors suggest would qualify for deficiency. Around half of those who used supplements were deficient. And yet, frustratingly, I could not find data on the effect of randomization to supplementation stratified by baseline vitamin D level. I even reached out to Dr Thomson to ask about this. She replied, “We did not stratify on baseline values because the numbers are too small statistically to test this.” Sorry.

In the meantime, I can tell you that for your “average woman,” vitamin D supplementation likely has no effect on mortality. It might modestly reduce the risk for certain cancers while increasing the risk for heart disease (probably through coronary calcification). So, there might be some room for personalization here. Perhaps women with a strong family history of cancer or other risk factors would do better with supplements, and those with a high risk for heart disease would do worse. Seems like a strategy that could be tested in a clinical trial. But maybe we could ask the participants to give up their extracurricular supplement use before they enter the trial. F. Perry Wilson, MD, MSCE, has disclosed no relevant financial relationships.

Long-Term Calcium and Vitamin D: Cancer Deaths Down, CVD Deaths Up in Older Women?

Article Type
Changed
Thu, 03/21/2024 - 09:17

Some doctors may be scratching their heads over a new analysis reporting that combined calcium and vitamin D (CaD) supplements appear to be associated with a slight 6% increase in cardiovascular (CVD) mortality, a slight 7% decrease in cancer risk, and no effect on osteoporotic fracture in postmenopausal women.

The study, in Annals of Internal Medicine, found no effect of supplementation on all-cause mortality.

The findings emerged from an analysis of more than 20 years’ follow-up data on a randomized trial in postmenopausal women conducted as part of the Women’s Health Initiative (WHI).

Cynthia A. Thomson, PhD, RD, first author and cancer prevention scientist at the Arizona Cancer Center and a professor of health promotion sciences at the University of Arizona in Tucson said the findings recommend individualized assessment of the need for supplements for older women as they consider them in hopes of preventing fractures.

Arizona Cancer Center
Dr. Cynthia A. Thomson


“Evaluate your patients individually and understand that there are some who may benefit from supplementation, for example, in terms of reducing colorectal cancer mortality,” Dr. Thomson said in an interview. The approach should be nuanced. “If you check the adequacy of vitamin D and calcium in their diets, supplementation may not be needed.” She added that supplementation is best considered in the context of a woman’s overall health profile, including risk factors for fracture, heart disease, and cancer, especially colorectal cancer (CRC).
 

Study Details

The investigators conducted postintervention follow-up of the WHI’s 7-year multicenter randomized intervention trial of CaD vs placebo.

Since existing evidence of long-term health outcomes was limited, the trial, begun in 1999 and closed in 2005, enrolled 36,282 postmenopausal women (mean age 62) with no history of breast or colorectal cancer. They were randomly assigned 1:1 to supplementation with 1000 mg of calcium carbonate (400 mg elemental calcium) plus 400 IU of vitamin D3 daily or placebo, taken twice daily in half doses.

Study outcomes were incidence of CRC, total and invasive breast cancer; disease-specific and all-cause mortality; total CVD; and hip fracture measured through December 2020, with analyses stratified by personal supplement usage.

Cancer. CaD was associated with reduced incident total cancer, CRC, and invasive breast cancer — notably among participants not taking CaD before randomization. Cancer incidence estimates varied widely, the authors noted, when stratified by supplement use before randomization. Noting that CaD seemed to have more cancer-related impact in those without prior supplementation, the authors suggested supplementation may affect cancer biology primarily by augmenting nutrient insufficiency.

An estimated 7% reduction in cancer mortality was observed after a median cumulative follow-up of 22.3 years: 1817 vs 1943 deaths (hazard ratio, 0.93; 95% CI, 0.87-0.99).

CVD. An estimated 6% increase in CVD mortality was seen in the CaD group: 2621 vs 2420 deaths (HR, 1.06; 95% CI, 1.01-1.12). Pretrial supplement users were found to be at higher CVD risk.

Hip fracture. No effect on hip fracture risk was measured, but the authors cautioned that hip fracture and CVD outcomes were available only for a subset of participants, and the effects of calcium alone vs vitamin D alone vs the combination could not be disentangled.

In a small subgroup analysis, some CaD users were seen to respond in terms of bone mineral density but since only 4 of the study’s 40 sites collected such information, the study was underpowered to examine the effect. ”Many other studies, however, show a response to supplementation in women who already have bone mineral deficits,” Dr. Thomson said.
 

 

 

The Calcification Question

One of the possible mechanisms of harm is that high-dose calcium supplements can increase the rate of blood coagulation and promote vascular calcification, said Emma Laing, PhD, RD, director of dietetics at the University of Georgia in Athens and a spokesperson for the Chicago-based Academy of Nutrition and Dietetics.

University of Georgia
Dr. Emma Laing

“Other factors that should be considered when determining a patient’s CVD risk are race, genetic predisposition, medical and social history, response to stress, and lifestyle behaviors, as well as the length of time supplements have been consumed,” added Dr. Laing, who was not involved in the WHI analysis.

“We asked ourselves if CaD supplements might contribute to calcification of the coronary arteries, since some believe this to be the case, although the literature is mixed,” said Dr. Thomson.

“So we did a shorter ancillary study in a small sample of several hundred [women] to see if there was any increase in calcification” and no difference was seen on imaging across the two arms. “However, women who were already on supplements before entering the study seemed to be at higher CVD risk,” she said.

Added study coauthor JoAnn E. Manson, MD, DrPH, chief of the division of preventive medicine at Brigham and Women’s Hospital and professor of women’s health at Harvard Medical School, both in Boston: “With no increase or decrease in coronary artery calcium at the end of the trial, we don’t believe starting or continuing calcium/vitamin D supplements should require screening for coronary artery disease.”

Some randomized trials and systematic reviews, however, have observed an increased risk of CVD in healthy patients on calcium supplements, with one Korean meta-analysis reporting a 15% increase in CVD risk in healthy postmenopausal women taking calcium supplements. Another meta-analysis found a link between calcium supplements and a greater risk of various cardiovascular outcomes, especially myocardial infarction.
 

Vitamin D Supplementation

As for vitamin D only supplementation, an updated meta-analysis including more than 83,000 individuals showed that it confers no cardiovascular protection and is therefore not indicated for this purpose.
 

Practice Considerations

Offering an outsider’s perspective, Sarah G. Candler, MD, MPH, an internist in Houston specializing in primary care for older high-risk adults, said: “Unfortunately, this latest study continues the trend of creating more questions than answers. If the adverse outcome of CVD death is a result of supplementation, it is unclear if this is due to the vitamin D, the calcium, or both. And it is unclear if this is dose dependent, time dependent, or due to concurrent risk factors unique to certain populations.

“It is recommended that patients at risk of osteoporosis based on age, sex, medications, and lifestyle be screened for osteoporosis and treated accordingly, including supplementation with CaD,” Dr. Candler said. “It remains unclear whether supplementation with CaD in the absence of osteoporosis and osteopenia is net beneficial or harmful, and at this time I would not recommend it to my patients.” 

Added Dr. Manson: “The very small increase seen in cardiovascular mortality wouldn’t be a reason to discontinue supplementation among women who have been advised by their healthcare providers to take these supplements for bone health or other purposes.

“Among those at usual risk of fracture, we recommend trying to obtain adequate calcium and vitamin D from food sources first and to use supplements only for the purpose of filling gaps in intake,” Dr. Manson continued. Overall, the findings support the national recommended dietary allowances for daily calcium intake of 1200 mg and daily vitamin D intake of 600-800 IU among postmenopausal women for maintenance of bone health, she said.

While a 2022 study found that vitamin D supplementation alone did not prevent fractures in healthy adults, other research has shown that a calcium/vitamin D combination is more likely to protect the skeleton.

“Patients at risk for fractures will probably benefit from calcium and/or vitamin D supplementation if they do not meet dietary intake requirements, have malabsorption syndromes, are taking medications that affect nutrient absorption, or if they are older and not regularly exposed to sunlight,” said Dr. Laing. “A combination of biochemical, imaging, functional, and dietary intake data can help determine if a supplement is warranted.”

She stressed that additional research is needed in more diverse populations before changing practice guidelines. “However, doctors should continue to weigh the risks and benefits of prescribing supplements for each patient.”

Some doctors may be scratching their heads over a new analysis reporting that combined calcium and vitamin D (CaD) supplements appear to be associated with a slight 6% increase in cardiovascular (CVD) mortality, a slight 7% decrease in cancer risk, and no effect on osteoporotic fracture in postmenopausal women.

The study, in Annals of Internal Medicine, found no effect of supplementation on all-cause mortality.

The findings emerged from an analysis of more than 20 years’ follow-up data on a randomized trial in postmenopausal women conducted as part of the Women’s Health Initiative (WHI).

Cynthia A. Thomson, PhD, RD, first author and cancer prevention scientist at the Arizona Cancer Center and a professor of health promotion sciences at the University of Arizona in Tucson said the findings recommend individualized assessment of the need for supplements for older women as they consider them in hopes of preventing fractures.

“Evaluate your patients individually and understand that there are some who may benefit from supplementation, for example, in terms of reducing colorectal cancer mortality,” Dr. Thomson said in an interview. The approach should be nuanced. “If you check the adequacy of vitamin D and calcium in their diets, supplementation may not be needed.” She added that supplementation is best considered in the context of a woman’s overall health profile, including risk factors for fracture, heart disease, and cancer, especially colorectal cancer (CRC).
 

Study Details

The investigators conducted postintervention follow-up of the WHI’s 7-year multicenter randomized intervention trial of CaD vs placebo.

Since existing evidence of long-term health outcomes was limited, the trial, begun in 1999 and closed in 2005, enrolled 36,282 postmenopausal women (mean age 62) with no history of breast or colorectal cancer. They were randomly assigned 1:1 to supplementation with 1000 mg of calcium carbonate (400 mg elemental calcium) plus 400 IU of vitamin D3 daily or placebo, taken twice daily in half doses.

Study outcomes were incidence of CRC, total and invasive breast cancer; disease-specific and all-cause mortality; total CVD; and hip fracture measured through December 2020, with analyses stratified by personal supplement usage.

Cancer. CaD was associated with reduced incident total cancer, CRC, and invasive breast cancer — notably among participants not taking CaD before randomization. Cancer incidence estimates varied widely, the authors noted, when stratified by supplement use before randomization. Noting that CaD seemed to have more cancer-related impact in those without prior supplementation, the authors suggested supplementation may affect cancer biology primarily by augmenting nutrient insufficiency.

An estimated 7% reduction in cancer mortality was observed after a median cumulative follow-up of 22.3 years: 1817 vs 1943 deaths (hazard ratio, 0.93; 95% CI, 0.87-0.99).

CVD. An estimated 6% increase in CVD mortality was seen in the CaD group: 2621 vs 2420 deaths (HR, 1.06; 95% CI, 1.01-1.12). Pretrial supplement users were found to be at higher CVD risk.

Hip fracture. No effect on hip fracture risk was measured, but the authors cautioned that hip fracture and CVD outcomes were available only for a subset of participants, and the effects of calcium alone vs vitamin D alone vs the combination could not be disentangled.

In a small subgroup analysis, some CaD users were seen to respond in terms of bone mineral density but since only 4 of the study’s 40 sites collected such information, the study was underpowered to examine the effect. ”Many other studies, however, show a response to supplementation in women who already have bone mineral deficits,” Dr. Thomson said.
 

 

 

The Calcification Question

One of the possible mechanisms of harm is that high-dose calcium supplements can increase the rate of blood coagulation and promote vascular calcification, said Emma Laing, PhD, RD, director of dietetics at the University of Georgia in Athens and a spokesperson for the Chicago-based Academy of Nutrition and Dietetics.

“Other factors that should be considered when determining a patient’s CVD risk are race, genetic predisposition, medical and social history, response to stress, and lifestyle behaviors, as well as the length of time supplements have been consumed,” added Dr. Laing, who was not involved in the WHI analysis.

“We asked ourselves if CaD supplements might contribute to calcification of the coronary arteries, since some believe this to be the case, although the literature is mixed,” said Dr. Thomson.

“So we did a shorter ancillary study in a small sample of several hundred [women] to see if there was any increase in calcification” and no difference was seen on imaging across the two arms. “However, women who were already on supplements before entering the study seemed to be at higher CVD risk,” she said.

Added study coauthor JoAnn E. Manson, MD, DrPH, chief of the division of preventive medicine at Brigham and Women’s Hospital and professor of women’s health at Harvard Medical School, both in Boston: “With no increase or decrease in coronary artery calcium at the end of the trial, we don’t believe starting or continuing calcium/vitamin D supplements should require screening for coronary artery disease.”

Skin Infections in Pregnant Women: Many Drugs Safe, but Not All

Article Type

SAN DIEGO — Multiple topical and systemic medications are safe for treating pregnant women with bacterial, viral, and fungal infections, a dermatologist told colleagues at the annual meeting of the American Academy of Dermatology. However, several drugs should be avoided or used with caution because of potential risks during pregnancy. 

When treating bacterial infections in pregnant women, there are many options, “especially for the sort of short-term antibiotic use that we tend to use for treating infections,” said Jenny Murase, MD, of the Palo Alto Foundation Medical Group and the University of California San Francisco.

Dr. Jenny E. Murase

During a presentation on treating infections in pregnant patients, she made the following recommendations for treating pyogenic infections: 

  • Impetigo: First-line treatments are topical mupirocin, oral first-generation cephalosporins, and oral dicloxacillin.
  • Cellulitis: Recommended treatments are oral or intravenous penicillin, oral first-generation cephalosporins, and oral dicloxacillin.
  • Methicillin-resistant Staphylococcus aureus (MRSA): “Clindamycin is first-line, dependent on bacteria culture and sensitivities,” and because of its safety, “it’s a really good choice for a pregnant woman.” Dr. Murase said. However, be aware of potential inducible resistance and test for the erm gene, she said.
  • Abscesses: Incision and drainage are recommended. “Whenever we’re managing a patient with a condition during pregnancy, we want to try to use nonmedications when possible,” Dr. Murase said. “No antibiotic is necessary unless the abscess is greater than 5 cm or if it’s greater than 2 cm with erythema around the abscess.”
  • Tuberculosis: The best strategy is rifampin, but peripartum vitamin K prophylaxis for mother and fetus should be used, she said. 

General Infections

With regard to antibiotics to treat general infections — for instance, if a patient with atopic dermatitis has a secondary skin infection — Dr. Murase recommended first-line oral antibiotic therapy with penicillin, first-generation cephalosporins, or dicloxacillin. For second-line therapy, erythromycin is the preferred macrolide over azithromycin and clarithromycin, she said. 

She noted that there is an increased risk for atrial/ventricular septal defects and pyloric stenosis associated with the use of erythromycin when used during the first trimester of pregnancy. In addition, erythromycin estolate increases the risk of liver toxicity, while erythromycin base and erythromycin ethylsuccinate do not. 

Sulfonamides are a second-line line choice up until the third trimester. If given to a patient in the first trimester, she said, “make sure that they are supplementing with folic acid efficiently, at least 0.5 mg a day.” During the peripartum period they are contraindicated, as they pose a risk for hemolytic anemia, hyperbilirubinemia, and kernicterus.

The combination drug trimethoprim/sulfamethoxazole is a second-line choice for complicated infections because of the associated risk for low birth weight and prematurity, Dr. Murase said.

Quinolones are also a second-line option during pregnancy she said, and ciprofloxacin and norfloxacin have been studied the most. “If you have to choose a quinolone for a complicated infection in pregnancy, those would be the quinolones of choice,” Dr. Murase said.

Considering the bad reputation of tetracyclines in pregnancy, dermatologists may be surprised to learn that they are considered a second-line therapy up to 14 weeks’ gestation, she said. After that time, however, they’re contraindicated because of bone growth inhibition, teeth discoloration, and maternal hepatitis.


 

 

 

Fungal Infections

As for fungal infections, clotrimazole is the first choice for topical treatment of tinea corporis, followed by miconazole and then ketoconazole, according to Dr. Murase. There are limited data for topical terbinafine, naftifine, and ciclopirox during pregnancy she noted, but they are likely safe.

There is also limited data about these drugs when used for topical treatment of candidiasis during pregnancy. Nystatin is safe, but less effective than other options, Dr. Murase said. Other options include clotrimazole, miconazole, and ketoconazole, which, in animals exposed to high doses, have not been associated with defects, and topical gentian violet (0.5%-1% solution), she noted.

For topical treatment of tinea versicolor during pregnancy, limited application of clotrimazole or miconazole is considered safe, and zinc pyrithione soap or topical benzoyl peroxide soap can be used for more widespread areas. 

Dr. Murase recommended caution when using selenium sulfide since poisoning has been linked to miscarriages, she said. Limited application appears to be safe, “so make sure that the patient is using it on smaller body surface areas.”

As for systemic antifungal treatments, fluconazole, ketoconazole, and itraconazole should be avoided in pregnancy because of the risks of craniosynostosis, congenital heart defects, and skeletal anomalies, Dr. Murase said. However, she referred to a study that found no increased risk of congenital malformations with fluconazole during the first trimester, and a patient could be reassured if, for example, she was treated for a yeast infection before she knew she was pregnant, she said.

Griseofulvin is not recommended during pregnancy, but a 2020 study suggests that terbinafine is safe, she said. In that study, oral or topical terbinafine did not appear to be associated with an increased risk for spontaneous abortion or major malformations. “Certainly, we can wait until after the pregnancy to treat onychomycosis. But I have had situations that even in spite of regular topical therapy, pregnant patients needed to take some kind of oral agent” because of severe itching. 

Viral Infections

For herpes simplex, acyclovir is the top choice, and famciclovir and valacyclovir (Valtrex) are likely safe, but daily prophylaxis is not recommended during pregnancy, Dr. Murase said. 

Because of a lack of data, podofilox, cantharidin, and imiquimod for treating human papillomavirus (HPV) should be avoided, she said. Podophyllin is extremely dangerous in pregnancy and has been linked to maternal and fetal deaths, and malformations, and is contraindicated in pregnancy, she added.

Instead, liquid nitrogen is the treatment of choice for HPV in pregnant patients, she said. 

Trichloracetic acid is the treatment of choice for condylomata acuminata, and squaric acid or intralesional Candida antigen injection for periungual verrucas can be used, she said, and limited applications of salicylic acid are considered safe. 

Dr. Murase highlighted a 2014 paper that she coauthored on the safety of dermatologic medications during pregnancy, noting that an updated report will be published later this year.

Dr. Murase disclosed relationships with Regeneron and UCB (speaker), Sanofi/Regeneron and Bristol-Myers Squibb (advisory board), and UCB, AbbVie, and UpToDate (consulting).

During a presentation on treating infections in pregnant patients, she made the following recommendations for treating pyogenic infections: 

  • Impetigo: First-line treatments are topical mupirocin, oral first-generation cephalosporins, and oral dicloxacillin.
  • Cellulitis: Recommended treatments are oral or intravenous penicillin, oral first-generation cephalosporins, and oral dicloxacillin.
  • Methicillin-resistant Staphylococcus aureus (MRSA): “Clindamycin is first-line, dependent on bacteria culture and sensitivities,” and because of its safety, “it’s a really good choice for a pregnant woman.” Dr. Murase said. However, be aware of potential inducible resistance and test for the erm gene, she said.
  • Abscesses: Incision and drainage are recommended. “Whenever we’re managing a patient with a condition during pregnancy, we want to try to use nonmedications when possible,” Dr. Murase said. “No antibiotic is necessary unless the abscess is greater than 5 cm or if it’s greater than 2 cm with erythema around the abscess.”
  • Tuberculosis: The best strategy is rifampin, but peripartum vitamin K prophylaxis for mother and fetus should be used, she said. 

General Infections

With regard to antibiotics to treat general infections — for instance, if a patient with atopic dermatitis has a secondary skin infection — Dr. Murase recommended first-line oral antibiotic therapy with penicillin, first-generation cephalosporins, or dicloxacillin. For second-line therapy, erythromycin is the preferred macrolide over azithromycin and clarithromycin, she said. 

She noted that there is an increased risk for atrial/ventricular septal defects and pyloric stenosis associated with the use of erythromycin when used during the first trimester of pregnancy. In addition, erythromycin estolate increases the risk of liver toxicity, while erythromycin base and erythromycin ethylsuccinate do not. 

Sulfonamides are a second-line line choice up until the third trimester. If given to a patient in the first trimester, she said, “make sure that they are supplementing with folic acid efficiently, at least 0.5 mg a day.” During the peripartum period they are contraindicated, as they pose a risk for hemolytic anemia, hyperbilirubinemia, and kernicterus.

The combination drug trimethoprim/sulfamethoxazole is a second-line choice for complicated infections because of the associated risk for low birth weight and prematurity, Dr. Murase said.

Quinolones are also a second-line option during pregnancy she said, and ciprofloxacin and norfloxacin have been studied the most. “If you have to choose a quinolone for a complicated infection in pregnancy, those would be the quinolones of choice,” Dr. Murase said.

Considering the bad reputation of tetracyclines in pregnancy, dermatologists may be surprised to learn that they are considered a second-line therapy up to 14 weeks’ gestation, she said. After that time, however, they’re contraindicated because of bone growth inhibition, teeth discoloration, and maternal hepatitis.


 

 

 

Fungal Infections

As for fungal infections, clotrimazole is the first choice for topical treatment of tinea corporis, followed by miconazole and then ketoconazole, according to Dr. Murase. There are limited data for topical terbinafine, naftifine, and ciclopirox during pregnancy she noted, but they are likely safe.

There is also limited data about these drugs when used for topical treatment of candidiasis during pregnancy. Nystatin is safe, but less effective than other options, Dr. Murase said. Other options include clotrimazole, miconazole, and ketoconazole, which, in animals exposed to high doses, have not been associated with defects, and topical gentian violet (0.5%-1% solution), she noted.

For topical treatment of tinea versicolor during pregnancy, limited application of clotrimazole or miconazole is considered safe, and zinc pyrithione soap or topical benzoyl peroxide soap can be used for more widespread areas. 

Dr. Murase recommended caution when using selenium sulfide since poisoning has been linked to miscarriages, she said. Limited application appears to be safe, “so make sure that the patient is using it on smaller body surface areas.”

As for systemic antifungal treatments, fluconazole, ketoconazole, and itraconazole should be avoided in pregnancy because of the risks of craniosynostosis, congenital heart defects, and skeletal anomalies, Dr. Murase said. However, she referred to a study that found no increased risk of congenital malformations with fluconazole during the first trimester, and a patient could be reassured if, for example, she was treated for a yeast infection before she knew she was pregnant, she said.

Griseofulvin is not recommended during pregnancy, but a 2020 study suggests that terbinafine is safe, she said. In that study, oral or topical terbinafine did not appear to be associated with an increased risk for spontaneous abortion or major malformations. “Certainly, we can wait until after the pregnancy to treat onychomycosis. But I have had situations that even in spite of regular topical therapy, pregnant patients needed to take some kind of oral agent” because of severe itching. 

Viral Infections

For herpes simplex, acyclovir is the top choice, and famciclovir and valacyclovir (Valtrex) are likely safe, but daily prophylaxis is not recommended during pregnancy, Dr. Murase said. 

Because of a lack of data, podofilox, cantharidin, and imiquimod for treating human papillomavirus (HPV) should be avoided, she said. Podophyllin is extremely dangerous in pregnancy and has been linked to maternal and fetal deaths, and malformations, and is contraindicated in pregnancy, she added.

Instead, liquid nitrogen is the treatment of choice for HPV in pregnant patients, she said. 

Trichloracetic acid is the treatment of choice for condylomata acuminata, and squaric acid or intralesional Candida antigen injection for periungual verrucas can be used, she said, and limited applications of salicylic acid are considered safe. 

Dr. Murase highlighted a 2014 paper that she coauthored on the safety of dermatologic medications during pregnancy, noting that an updated report will be published later this year.

Dr. Murase disclosed relationships with Regeneron and UCB (speaker), Sanofi/Regeneron and Bristol-Myers Squibb (advisory board), and UCB, AbbVie, and UpToDate (consulting).

This transcript has been edited for clarity.

Rachel S. Rubin, MD: I’m Dr. Rachel Rubin, urologist and sexual medicine specialist in the Washington, DC, area. We are coming to you live from the Mayo Clinic Urology Conference in Maui, Hawaii, with the world’s leading experts in men’s health, sexual health, and quality of life. I’m bringing in Dr. Allen Morey from the North Dallas area, one of the world’s leading experts in reconstructive urology. He deals with all things urinary incontinence, penile curvature, and sexual health.

Dr. Morey said something at this conference that really put my chin on the floor. He said, “The urethra is a sex organ. It is androgen dependent.” This is so important because it’s true for all genders. So, Dr. Morey, tell us more about why you made that comment and about the incontinence in men that you deal with all the time.

Allen F. Morey, MD: For many years, I’ve worked at cancer centers where, through the various treatments for prostate cancer, the men suffered from urinary incontinence and we put a lot of artificial urinary sphincters in those patients. I had one patient who asked, “Why do I keep having this erosion?” Of course, the erosion is where the cuff compresses the tissue surrounding the urethra, and the tissue gives way, leaving a hole in the urethra. I looked at him and noticed that he was pale. And I thought, Let me check his testosterone level. We started checking it on everybody who had this problem, and sure enough, the ones who had the cup erosion — who had the atrophic tissue around the urethra — most of them had low testosterone levels. Some of this was due to the cancer treatment, but in other men, it was just due to old age.

We started thinking that this is a causal relationship. And we tested it. I had a fellow who was a board-certified pathologist before becoming a urologist. He obtained some specimens from the urethra and did very sophisticated, elegant stains on that tissue. We found that it’s just erectile tissue surrounding the urethra. That’s why I call it a sex organ. I tell my patients, “When you are a teenager, this tissue is thin, like on your pinky finger. As you get older, it becomes thicker. And then as you get even older, and you may be having cancer treatment, that tissue is gone.” You can show them your little finger; it’s about that size. All the meat is off the bone. There’s nothing left protecting the urinary mucosa from the device.

That’s why it’s important to maintain the optimal health of those tissues and for them to remain dry. Because let’s face it: Urinary incontinence is a horrible quality of life. These are my happiest patients when we fix it. Before that, when they go on vacation, they have a separate suitcase filled with diapers. They can’t go anywhere. They can’t do anything. When they become incontinent after the prostatectomy, they gain weight. And when you put in the device to treat it, they lose weight and you can track it. The urinary incontinence patients really suffer. And we need to consider the medical optimization of those patients.

Dr. Rubin: It’s so important, and I love how analogous this is to our female patients. We know that incontinence is devastating to our female patients as well, and there’s a lot of hope. As we get older we start to pee every time we cough, laugh, or sneeze. Men are a little more bothered by it when it happens; they don’t expect it. Among women, it’s thought of as normal, but it’s not normal. There is so much we can do to help these patients, ranging from conservative treatment to surgical therapies.

The connection between hormones and urethral health is true on the female side as well. As you go through menopause, the urethral tissue thins out, gets dry, gets irritated, and can cause worsening incontinence, pain with sex, and genital urinary syndrome of menopause. It’s really important.

For our primary care doctors, how should we talk about stress incontinence in men? How do we diagnose it?

Dr. Morey: It’s easy to diagnose. Just do a quick history. Find out how many pads a day they are using. You have to ask the question, and then you have them stand up and look inside their underwear. You’ll see what kind of pad they are wearing. Is it just a shield or are they actually wearing full diapers? Then I have them do a standing cough test. I stand off to the side, holding a couple of towels, and have the patient cough four times. I can tell if it’s a full stream or just a couple of drops. Is it nothing but they are wearing a pad? You match up what you see with their experience, and in an instant it tells you how severe their problem is and it helps you direct them on to further treatment, because many patients have treatment fatigue. They’ve already been through the system. They have really suffered and they don’t know which way to go. They don’t know what’s available.

Dr. Rubin: On the female side, we have pelvic floor physical therapy. We have pads and devices that you can wear, and pessaries. We have surgical options, like bulking agents into the urethra as well as urethral slings, which can be quite helpful for women. So there’s a lot of hope out there for women, and from what I learned from you at this conference, there’s a lot of hope for men as well. So talk us through treatment, from conservative to surgical options.

Dr. Morey: There hasn’t been much innovation in male incontinence treatment over the past few decades, but we’re starting to see signs of new products appearing on the horizon, so I’m very optimistic that in the next 5 or 10 years, we’ll have more. But right now it comes down to slings and artificial sphincters, which are devices with little pumps and hydraulics, and they’re very good. But they’ve been around for 50 years, and they have this other potential risk factor of the erosion of the tissue.

We don’t have a pill that we can give the patient to tighten up those muscles. We can help them with overactive bladder. But maybe the hormonal influence is a way to optimize the health of the tissue so that these surgical treatments can really deliver the best outcomes. And as I always say, and having treated so many of these patients, it’s really a game of millimeters — how much coaptation you get. If you’re off by the slightest amount, that’s an unhappy patient. So it doesn’t take much to make it a lot better.

Dr. Rubin: There’s so much hope for our patients, and this can really have an effect on sexual health. You know the benefits you see in their quality of life and sexual health when you can stop leakage.

Dr. Morey: I always take care of the waterworks first. Many of the men have both urinary problems and erectile problems. Nobody feels sexy when they’re leaking urine all over their partner. So first we take care of that. And then, in the motivated younger patients, we bring them back and talk to them about potentially having a second operation.

Dr. Rubin: And so similarly, in women with urinary incontinence, it can have a major impact on sexual health — how they show up and how they talk to their partner. So, it is really important for our primary care docs to talk to patients about urinary incontinence and not just say, “Oh, well, you’re getting older. There’s nothing that you can do.” There’s actually no age at which there is nothing that we can do. And it’s really important to refer patients to those urologists who have extra training in incontinence and sexual health, because we do care about these quality-of-life measures and there is a lot we can do, ranging from conservative to more invasive treatments. But patients really should have options.

Dr. Morey: I heard during this meeting that urinary incontinence was the number-one source of treatment regret among patients who had their prostate treated for cancer. So, this is a really big deal for our patients. And it impacts wellness, quality of life, and overall well-being.

Dr. Rubin: When we are counseling patients for cancer surgeries or cancer treatments such as radiation therapy, it’s really hard for the patients who have never had urinary incontinence to imagine what that might be like. When you’re telling them they could have a stroke or a heart attack, or they could have erectile dysfunction or urinary incontinence, it all sounds similar to them. It could happen to someone else. It’s very hard to truly counsel patients on these quality-of-life issues that they’ve never encountered before.

Dr. Morey: We have found that it takes a long time for patients to get into our office for treatment, and it’s unbelievable — often 5 years in diapers before they find us.

Dr. Rubin: Hopefully videos like this will teach our docs and our patients that there is hope out there, that you don’t need to wait through years of suffering from incontinence. So, how does somebody find a reconstructive urologist or a sexual medicine urologist?

Dr. Morey: There are a couple of good websites out there, such as fixincontinence.com and edcure.org. The device manufacturers have pretty good information for patients.

Dr. Rubin: The Sexual Medicine Society of North America (SMSNA) has a great find-a-provider website, which provides a list of urologists who are trained in both sexual health and urinary incontinence, because they both matter. Our patients deeply care about these issues.

Rachel S. Rubin, MD, has disclosed the following relevant financial relationships: Serve(d) as a speaker for Sprout; received research grant from Maternal Medical; received income in an amount equal to or greater than $250 from Absorption Pharmaceuticals, GSK, Endo.

Dr. Morey: I heard during this meeting that urinary incontinence was the number-one source of treatment regret among patients who had their prostate treated for cancer. So, this is a really big deal for our patients. And it impacts wellness, quality of life, and overall well-being.

Dr. Rubin: When we are counseling patients for cancer surgeries or cancer treatments such as radiation therapy, it’s really hard for the patients who have never had urinary incontinence to imagine what that might be like. When you’re telling them they could have a stroke or a heart attack, or they could have erectile dysfunction or urinary incontinence, it all sounds similar to them. It could happen to someone else. It’s very hard to truly counsel patients on these quality-of-life issues that they’ve never encountered before.

Dr. Morey: We have found that it takes a long time for patients to get into our office for treatment, and it’s unbelievable — often 5 years in diapers before they find us.

Dr. Rubin: Hopefully videos like this will teach our docs and our patients that there is hope out there, that you don’t need to wait through years of suffering from incontinence. So, how does somebody find a reconstructive urologist or a sexual medicine urologist?

Dr. Morey: There are a couple of good websites out there, such as fixincontinence.com and edcure.org. The device manufacturers have pretty good information for patients.

Dr. Rubin: The Sexual Medicine Society of North America (SMSNA) has a great find-a-provider website, which provides a list of urologists who are trained in both sexual health and urinary incontinence, because they both matter. Our patients deeply care about these issues.

Rachel S. Rubin, MD, has disclosed the following relevant financial relationships: Serve(d) as a speaker for Sprout; received research grant from Maternal Medical; received income in an amount equal to or greater than $250 from Absorption Pharmaceuticals, GSK, Endo.

Does Exercise Reduce Cancer Risk? It’s Just Not That Simple

“Exercise is medicine” has become something of a mantra, with good reason. There’s no doubt that regular physical activity has a broad range of health benefits. Exercise can improve circulation, help control weight, reduce stress, and boost mood — take your pick.

Lower cancer risk is also on the list — with exercise promoted as a risk-cutting strategy in government guidelines and in recommendations from professional groups such as the American Cancer Society.

Despite confidently worded recommendations, the relationship between exercise and cancer risk is much less certain than the guidelines would suggest. The bulk of the data hangs on less rigorous, observational studies that have linked physical activity to lower risks for certain cancers, but plenty of questions remain.

What are the cancer types where exercise makes a difference? How significant is that impact? And what, exactly, defines a physical activity pattern powerful enough to move the needle on cancer risk?

Here’s an overview of the state of the evidence.

Exercise and Cancer Types: A Mixed Bag

When it comes to cancer prevention strategies, guidelines uniformly endorse less couch time and more movement. But a deeper look at the science reveals a complex and often poorly understood connection between exercise and cancer risk.

For certain cancer types, the benefits of exercise on cancer risk seem fairly well established.

The latest edition of the Physical Activity Guidelines for Americans, published in 2018, cites “strong evidence” that regular exercise might curb the risks for breast and colon cancers as well as bladder, endometrial, esophageal, kidney, and gastric cancers. These guidelines also point to “moderate”-strength evidence of a protective association with lung cancer.

The evidence of a protective effect, however, is strongest for breast and colon cancers, said Jennifer Ligibel, MD, senior physician in the Breast Oncology Center at Dana-Farber Cancer Institute, Boston, . “But,” she pointed out, “that may be because they’re some of the most common cancers, and it’s been easier to detect an association.”

Guidelines from the American Cancer Society, published in 2020, align with the 2018 recommendations. 

“We believe there’s strong evidence to suggest at least eight different types of cancer are associated with physical activity,” said Erika Rees-Punia, PhD, MPH, senior principal scientist, epidemiology and behavioral research at the American Cancer Society.

That view is not universal, however. Current recommendations from the World Cancer Research Fund and American Institute for Cancer Research, for example, are more circumspect, citing only three cancers with good evidence of a protective effect from exercise: Breast (postmenopausal), colon, and endometrial.

“We definitely can’t say exercise reduces the risk of all cancers,” said Lee Jones, PhD, head of the Exercise Oncology Program at Memorial Sloan Kettering Cancer Center in New York City. “The data suggest it’s just not that simple.”

And it’s challenging to put all the evidence together, Dr. Jones added.

The physical activity guidelines are based on published systematic reviews, meta-analyses, and pooled analyses of data from observational studies that examined the relationship between physical activity — aerobic exercise, specifically — and cancer incidence. That means the evidence comes with all the limitations observational studies entail, such as how they collect information on participants’ exercise habits — which, Dr. Jones noted, is typically done via “monster questionnaires” that gauge physical activity in broad strokes.

Pooling all those findings into a meta-analysis is tricky, Dr. Jones added, because individual studies vary in important ways — from follow-up periods to how they quantify exercise and track cancer incidence.

In a study published in February in Cancer Cell, Dr. Jones and his colleagues attempted to address some of those issues by leveraging data from the PLCO screening trial.

The PLCO was a prospective study of over 60,000 US adults that compared the effects of annual screening vs usual care on cancer mortality. At enrollment, participants completed questionnaires that included an assessment of “vigorous” exercise. Based on that, Dr. Jones and his colleagues classified 55% as “exercisers” — meaning they reported 2 or more hours of vigorous exercise per week. The remaining 45%, who were in the 0 to 1 hour per week range, were deemed non-exercisers.

Over a median of 18 years, nearly 16,000 first-time invasive cancers were diagnosed, and some interesting differences between exercisers and non-exercisers emerged. The active group had lower risks for three cancers: Head and neck, with a 26% lower risk (hazard ratio [HR], 0.74), lung (a 20% lower risk), and breast (an 11% lower risk).

What was striking, however, was the lack of connection between exercise and many cancers cited in the guidelines, including colon, gastric, bladder, endometrial, and renal cancers.

Perhaps even more surprising — exercisers had higher risks for prostate cancer (12%) and melanoma (20%). This finding, Dr. Jones said, is in line with a previous pooled analysis of data from 12 US and European prospective cohorts. In this study, the most physically active participants (90th percentile) had higher risks for melanoma and prostate cancer, compared with the least active group (10th percentile).

The melanoma findings do make sense, Dr. Jones said, given that highly active people may spend a lot of time in the sun. “My advice,” Dr. Jones said, “is, if you’re exercising outside, wear sunscreen.” The prostate cancer findings, however, are more puzzling and warrant further research, he noted.

But the bottom line is that the relationship between exercise and cancer types is mixed and far from nailed down.

 

 

How Big Is the Effect?

Even if exercise reduces the risk for only certain cancers, that’s still important, particularly when those links appear strongest for common cancer types, such as breast and colon.

But how much of a difference can exercise make?

Based on the evidence, it may only be a modest one. A 2019 systematic review by the Physical Activity Guidelines Advisory Committee provided a rough estimate: Across hundreds of epidemiological studies, people with the highest physical activity levels had a 10%-20% lower risk for the cancers cited in the 2018 exercise guidelines compared with people who were least active.

These figures, however, are probably an underestimate, said Anne McTiernan, MD, PhD, a member of the advisory committee and professor of epidemiology, at Fred Hutchinson Cancer Center, Seattle.

“This is what we usually see when a factor is not measured very well,” said Dr. McTiernan, explaining that the individual studies differed in their categories of “highest” and “lowest” physical activity, such that one study’s “highest” could be another’s mid-range.

“In other words, the effects of physical activity are likely larger” than the review found, Dr. McTiernan said.

The next logical question is whether a bigger exercise “dose” — more time or higher intensity — would have a greater impact on cancer risk. A 2019 study published in the Journal of Clinical Oncology tried to clarify that by pooling data on over 750,000 participants from nine prospective cohorts.

Overall, people meeting government recommendations for exercise — equivalent to about 2.5-5 hours of weekly moderate activity, such as a brisk walk, or about 1.25-2.5 hours of more vigorous activities, like running — had lower risks for seven of 15 cancer types studied compared with less active people.

For cancers with positive findings, being on the higher end of the recommended 2.5- to 5-hour weekly range was better. Risk reductions for breast cancer, for instance, were 6% at 2.5 hours of physical activity per week and 10% at 5 hours per week. Similar trends emerged for other cancer types, including colon (8%-14%), endometrial (10%-18%), liver cancer (18%-27%), and non-Hodgkin lymphoma in women (11%-18%).

But there may be an exercise sweet spot that maximizes the cancer risk benefit.

Among people who surpassed the recommendations — exercising for more time or more intensely — the risk reduction benefit did not necessarily improve in a linear fashion. For certain cancer types, such as colon and endometrial, the benefits of more vigorous exercise “eroded at higher levels of activity,” the authors said.

The issue here is that most studies have not dug deeply into aerobic exercise habits. Often, studies present participants with a list of activities — walking, biking, and running — and ask them to estimate how often and for what duration they do each.

Plus, “we’ve usually lumped moderate and vigorous activities together,” Dr. Rees-Punia said, which means there’s a lack of “granular data” to say whether certain intensities or frequencies of exercise are optimal and for whom.

Why Exercise May Lower Cancer Risk

Exercise habits do not, of course, exist in a vacuum. Highly active people, Dr. Ligibel said, tend to be of higher socioeconomic status, leaner, and have generally healthier lifestyles than sedentary people.

Body weight is a big confounder as well. However, Dr. Rees-Punia noted, it’s also probably a reason that exercise is linked to lower cancer risks, particularly by preventing weight gain. Still, studies have found that the association between exercise and many cancers remains significant after adjusting for body mass index.

The why remains unclear, though some studies offer clues.

“There’s been some really interesting mechanistic research, suggesting that exercise may help inhibit tumor growth or upregulate the immune system,” Dr. Ligibel said.

That includes not only lab research but small intervention studies. While these studies have largely involved people who already have cancer, some have also focused on healthy individuals.

2019 study from Dr. Ligibel and her colleagues, which randomly assigned 49 women newly diagnosed with breast cancer to start either an exercise program or mind-body practices ahead of surgery, found exercisers, who had been active for about a month at the time of surgery, showed signs of immune system upregulation in their tumors, while the control group did not.

Among healthy postmenopausal women, a meta-analysis of six clinical trials from Dr. McTiernan and her colleagues found that exercise plus calorie reduction can reduce levels of breast cancer-related endogenous hormones, more so than calorie-cutting alone. And a 2023 study found that high-intensity exercise boosted the ranks of certain immune cells and reduced inflammation in the colon among people at high risk for colon and endometrial cancers due to Lynch syndrome.

Defining an Exercise ‘Prescription’

Despite the gaps and uncertainties in the research, government guidelines as well as those from the American Cancer Society and other medical groups are in lockstep in their exercise recommendations: Adults should strive for 150-300 minutes of moderate-intensity aerobic exercise (like brisk walking), 75-150 minutes of vigorous activity (like running), or some combination each week.

The guidelines also encourage strength training twice a week — advice that’s based on research tying those activity levels to lower risks for heart disease, diabetes, and other chronic conditions.

But there’s no “best” exercise prescription for lowering cancer risk specifically. Most epidemiological studies have examined only aerobic activity, Dr. Rees-Punia said, and there’s very little known about whether strength conditioning or other moderate heart rate-elevating activities, such as daily household chores, may reduce the risk for cancer.

Given the lack of nuance in the literature, it’s hard to say what intensities, types, or amounts of exercise are best for each individual.

Going forward, device-based measurements of physical activity could “help us sort out the effects of different intensities of exercise and possibly types,” Dr. Rees-Punia said.

But overall, Dr. McTiernan said, the data do show that the risks for several cancers are lower at the widely recommended activity levels.

“The bottom-line advice is still to exercise at least 150 minutes per week at a moderate-intensity level or greater,” Dr. McTiernan said.

Or put another way, moving beats being sedentary. It’s probably wise for everyone to sit less, noted Dr. Rees-Punia, for overall health and based on evidence tying sedentary time to the risks for certain cancers, including colon, endometrial, and lung.

There’s a practical element to consider in all of this: What physical activities will people actually do on the regular? In the big epidemiological studies, Dr. McTiernan noted, middle-aged and older adults most often report walking, suggesting that’s the preferred, or most accessible activity, for many.

“You can only benefit from the physical activity you’ll actually do,” Dr. Rees-Punia said.

Dr. Ligibel echoed that sentiment, saying she encourages patients to think about physical activity as a process: “You need to find things you like to do and work them into your daily life, in a sustainable way.

“People often talk about exercise being medicine,” Dr. Ligibel said. “But I think you could take that too far. If we get too prescriptive about it, that could take the joy away.”

The next logical question is whether a bigger exercise “dose” — more time or higher intensity — would have a greater impact on cancer risk. A 2019 study published in the Journal of Clinical Oncology tried to clarify that by pooling data on over 750,000 participants from nine prospective cohorts.

Overall, people meeting government recommendations for exercise — equivalent to about 2.5-5 hours of weekly moderate activity, such as a brisk walk, or about 1.25-2.5 hours of more vigorous activities, like running — had lower risks for seven of 15 cancer types studied compared with less active people.

For cancers with positive findings, being on the higher end of the recommended 2.5- to 5-hour weekly range was better. Risk reductions for breast cancer, for instance, were 6% at 2.5 hours of physical activity per week and 10% at 5 hours per week. Similar trends emerged for other cancer types, including colon (8%-14%), endometrial (10%-18%), liver cancer (18%-27%), and non-Hodgkin lymphoma in women (11%-18%).

But there may be an exercise sweet spot that maximizes the cancer risk benefit.

Among people who surpassed the recommendations — exercising for more time or more intensely — the risk reduction benefit did not necessarily improve in a linear fashion. For certain cancer types, such as colon and endometrial, the benefits of more vigorous exercise “eroded at higher levels of activity,” the authors said.

The issue here is that most studies have not dug deeply into aerobic exercise habits. Often, studies present participants with a list of activities — walking, biking, and running — and ask them to estimate how often and for what duration they do each.

Plus, “we’ve usually lumped moderate and vigorous activities together,” Dr. Rees-Punia said, which means there’s a lack of “granular data” to say whether certain intensities or frequencies of exercise are optimal and for whom.

Why Exercise May Lower Cancer Risk

Exercise habits do not, of course, exist in a vacuum. Highly active people, Dr. Ligibel said, tend to be of higher socioeconomic status, leaner, and have generally healthier lifestyles than sedentary people.

Body weight is a big confounder as well. However, Dr. Rees-Punia noted, it’s also probably a reason that exercise is linked to lower cancer risks, particularly by preventing weight gain. Still, studies have found that the association between exercise and many cancers remains significant after adjusting for body mass index.

The why remains unclear, though some studies offer clues.

“There’s been some really interesting mechanistic research, suggesting that exercise may help inhibit tumor growth or upregulate the immune system,” Dr. Ligibel said.

That includes not only lab research but small intervention studies. While these studies have largely involved people who already have cancer, some have also focused on healthy individuals.

2019 study from Dr. Ligibel and her colleagues, which randomly assigned 49 women newly diagnosed with breast cancer to start either an exercise program or mind-body practices ahead of surgery, found exercisers, who had been active for about a month at the time of surgery, showed signs of immune system upregulation in their tumors, while the control group did not.

Among healthy postmenopausal women, a meta-analysis of six clinical trials from Dr. McTiernan and her colleagues found that exercise plus calorie reduction can reduce levels of breast cancer-related endogenous hormones, more so than calorie-cutting alone. And a 2023 study found that high-intensity exercise boosted the ranks of certain immune cells and reduced inflammation in the colon among people at high risk for colon and endometrial cancers due to Lynch syndrome.

Defining an Exercise ‘Prescription’

Despite the gaps and uncertainties in the research, government guidelines as well as those from the American Cancer Society and other medical groups are in lockstep in their exercise recommendations: Adults should strive for 150-300 minutes of moderate-intensity aerobic exercise (like brisk walking), 75-150 minutes of vigorous activity (like running), or some combination each week.

The guidelines also encourage strength training twice a week — advice that’s based on research tying those activity levels to lower risks for heart disease, diabetes, and other chronic conditions.

But there’s no “best” exercise prescription for lowering cancer risk specifically. Most epidemiological studies have examined only aerobic activity, Dr. Rees-Punia said, and there’s very little known about whether strength conditioning or other moderate heart rate-elevating activities, such as daily household chores, may reduce the risk for cancer.

Given the lack of nuance in the literature, it’s hard to say what intensities, types, or amounts of exercise are best for each individual.

Going forward, device-based measurements of physical activity could “help us sort out the effects of different intensities of exercise and possibly types,” Dr. Rees-Punia said.

But overall, Dr. McTiernan said, the data do show that the risks for several cancers are lower at the widely recommended activity levels.

“The bottom-line advice is still to exercise at least 150 minutes per week at a moderate-intensity level or greater,” Dr. McTiernan said.

Or put another way, moving beats being sedentary. It’s probably wise for everyone to sit less, noted Dr. Rees-Punia, for overall health and based on evidence tying sedentary time to the risks for certain cancers, including colon, endometrial, and lung.

There’s a practical element to consider in all of this: What physical activities will people actually do on the regular? In the big epidemiological studies, Dr. McTiernan noted, middle-aged and older adults most often report walking, suggesting that’s the preferred, or most accessible activity, for many.

“You can only benefit from the physical activity you’ll actually do,” Dr. Rees-Punia said.

Dr. Ligibel echoed that sentiment, saying she encourages patients to think about physical activity as a process: “You need to find things you like to do and work them into your daily life, in a sustainable way.

“People often talk about exercise being medicine,” Dr. Ligibel said. “But I think you could take that too far. If we get too prescriptive about it, that could take the joy away.”

California Pushes to Expand the Universe of Abortion Care Providers

Article Type
Changed
Wed, 03/06/2024 - 16:44

California’s efforts to expand access to abortion care are enabling more types of medical practitioners to perform certain abortion procedures — potentially a boon for patients in rural areas especially, but a source of concern for doctors’ groups that have long fought efforts to expand the role of non-physicians.

The latest move is a law that enables trained physician assistants, also known as physician associates, to perform first-trimester abortions without a supervising physician present. The measure, which passed last year and took effect Jan. 1, also lets PAs who have been disciplined or convicted solely for performing an abortion in a state where the practice is restricted apply for a license in California.

Physician assistants are now on par with nurse practitioners and certified nurse midwives trained in abortion care, who in 2022 won the ability to perform abortions without a doctor present.

The need for more abortion care practitioners is being driven by efforts in many states to gut abortion rights following the Supreme Court’s 2022 decision ending constitutional protection for the procedure. Thirty-one states have implemented abortion restrictions that range from cutting federal funding for abortion coverage to outright bans, according to the Guttmacher Institute, a research organization concerned with reproductive health.

With the new law, “there will be fewer barriers, and shorter wait times for this essential service,” said Jeremy Meis, president-elect of the California Academy of Physician Associates. While it is unclear how many of California’s 16,000 PAs will be trained in performing abortions, research shows that PAs are more likely than physicians to practice in rural areas where access to abortion is limited. More than 40% of counties in California lack clinics that provide abortion.

Comparing data from the first six months of 2020 with the same period in 2023, the number of abortions jumped from 77,030 to 92,600 a 20% increase as the state became a refuge for women seeking abortions. California has passed a suite of reproductive health laws to build in protections and increase access, and a dozen other states, including Oregon, Minnesota, and New York, have mounted similar efforts. Seventeen states, including California, now allow PAs to perform first-trimester abortions, according to the American Academy of Physician Associates.

There was little opposition to the new California law, with two physicians’ groups supporting it. But the American Medical Association, the country’s most powerful doctors’ lobby, has fought vigorously against what it calls “scope creep” — that is, changes that allow clinicians like PAs to do medical procedures independent of physicians.

“Our policy stance is the same on scope of practice expansion regardless of procedure,” noted Kelly Jakubek, the AMA’s media relations manager. The AMA’s website points to legislative victories in 2023, including striking down “legislation allowing physician assistants to practice independently without physician oversight,” in states including Arizona and New York. The AMA did not take a formal position on the California legislation. Its local chapter, the California Medical Association, took a neutral position on the legislation.

In preparation for the new law, one physician assistant at Planned Parenthood Pasadena & San Gabriel Valley began learning how to perform aspiration abortions — a procedure also known as dilation and curettage that uses gentle suction to end a pregnancy — at the end of last year. The PA, who requested anonymity due to concerns about safety, said that with abortion restrictions in place around the country, “I just think it’s really important to be able to provide a comfortable, safe, and very effective way to terminate a pregnancy for patients.”

She is now one of six PAs and midwives at her clinic who can offer aspiration abortions. To reach competency, she participated in 50 procedures and learned how to administer medication that eases pain and anxiety. Such conscious sedation, as it is known, is frequently used for first-trimester abortions. Now she, like any other advanced practice clinician who has obtained skills in performing abortions, can train her peers — another feature of the new law.

The length of time for training and the number of procedures to reach competency varies based on a practitioner’s previous experience.

“It’s encouraging this cross-profession training and collaborations, which is really important when we’re looking at increasing access to essential services,” said Jessica Dieseldorff, senior program manager of abortion services at Planned Parenthood Mar Monte in Santa Cruz.

In December, California committed $18 million to help accelerate training in abortion and reproductive care for practitioners, including PAs, through the Reproductive Health Care Access Initiative.

Dieseldorff, a nurse practitioner who trains other advanced-practice clinicians in abortion care, said that rural communities, in particular, will reap the benefits since many rely solely on physician assistants and other allied clinicians.

Reflecting on her career, she said much has changed since she became a nurse 25 years ago. At that time, she worked only as support staff to doctors providing abortions.

“When I began, medication abortions did not exist in this country,” she said, referring to the practice of using two drugs often prescribed to induce abortions. “It’s been gratifying to be able to progress and become a provider myself, provide non-stigmatizing and compassionate and safe care to patients; and now, at this stage in my career to be training others to do the same.”

Thyroid Disorders and Gynecologic Cancers: Is There a Link?

Article Type
Changed
Fri, 03/01/2024 - 12:09

 

TOPLINE:

The risk of developing gynecologic cancer is lower in women with hyperthyroidism than in those without it, found a large study. 

METHODOLOGY:

  • Thyroid disease and altered thyroid hormone expression can affect ovulation, endometrial physiology, and estrogen levels, but studies of the association with gynecologic cancer risk have conflicting results.
  • This population-based cohort study used data from the Taiwan National Health Insurance Research Database to identify women (mean age, 44 years) who were diagnosed with thyroid disease between January 2000 and December 2018.
  • Propensity scores were used to pair 296,872 women with hyperthyroidism and 44,852 with hypothyroidism in a 1:1 ratio with an equal number of individuals without thyroid disorders.
  • The cohort was followed up from the date of first diagnosis of hypothyroidism or hyperthyroidism until the diagnosis of gynecologic cancers (endometrial cancer, uterine corpus cancer, and ovarian cancer), death, or the end of 2018.

TAKEAWAY:

  • Women with hyperthyroidism had a lower risk for all gynecologic cancers than those without hyperthyroidism (adjusted hazard ratio [aHR], 0.86; P = .0084).
  • The risk of developing gynecologic cancer was lower among women with hyperthyroidism aged 20-40 years (aHR, 0.72; P = .0043) but not among those aged > 40 years.
  • The reduced risk for gynecologic cancers associated with hyperthyroidism persisted even beyond 6 years of follow-up (aHR, 0.75; P < .001).
  • A trend toward a slightly increased risk for gynecologic cancer was observed among women with hypothyroidism; however, the association was not statistically significant.

IN PRACTICE:

The findings may alert oncologists and healthcare decision-makers toward gynecologic cancer trends and prompt further research to understand the mechanism by which thyroid hormone regulates reproductive function, the authors noted.

SOURCE:

This study was led by John Hang Leung from the Ditmanson Medical Foundation Chia-Yi Christian Hospital, Chiayi, Taiwan, and published online in Scientific Reports.

LIMITATIONS:

The study data were obtained from administrative claims databases, so there is a possibility of underestimation or overestimation. Lifestyle factors such as obesity and alcoholism are difficult to measure, so the risk for gynecologic cancers linked to thyroid dysfunction may have been underestimated. Furthermore, because of nonavailability of laboratory data, thyroid hormone status at diagnosis could not be linked to gynecological cancer risk.

DISCLOSURES:

This study was supported by An-Nan Hospital, China Medical University, Tainan, Taiwan. The authors declared no financial interests or conflicts related to the study.
