There is a link between cannabis exposure during pregnancy and higher fasting glucose levels and adiposity in the offspring in early childhood, a new study suggests.

Research looking at the effect of prenatal exposure to cannabis on offspring is growing. It is known to affect childhood cognition and behavior; however, there is little work to date on how it affects metabolic outcomes, said lead author Brianna F. Moore, PhD.

“Officially, the American Academy of Obstetricians and Gynecologists recommends that women do not use cannabis during pregnancy or while breastfeeding to limit the effects on offspring. There’s really a lot we don’t know, but researchers across the country are starting to look into this more, and there are signs that it isn’t great for the offspring,” Dr. Moore, assistant professor at the Colorado School of Public Health in Aurora, said in an interview.

And she noted that while some women turn to cannabis to manage the challenging symptoms of pregnancy, “Clinicians should encourage pregnant women to refrain from using cannabis; it is best for these pregnant women to talk to their physicians about alternative ways of managing these symptoms.”

The findings were published online March 31 in the Journal of Clinical Endocrinology & Metabolism.
 

Study of mother and 5-year-old child pairs

The researchers assessed 103 sets of mothers and children from the Healthy Start study. At 27 weeks of gestation, the investigators assessed 12 metabolites of cannabis/cannabinoids in urine samples. Results from these samples were used to categorize fetal exposure to cannabis as either not exposed or exposed. They found that about 15% of the mothers had traceable amounts of cannabinoids, suggesting fetal cannabis exposure.

At follow-up, the study team assessed fat-free mass and fat mass using air displacement plethysmography among the offspring around age 5. They used generalized linear models to approximate the relationship between fetal exposure to cannabis with metabolic measures such as insulin, glucose, and homeostatic model assessment of insulin resistance (HOMA-IR), and adiposity measures such as body mass index, fat-free mass, fat mass, adiposity, and BMI z-scores.

The findings showed that, compared with nonexposed offspring, exposed offspring had greater:

• Fasting glucose (5.6 mg/dL; 95% confidence interval [CI], 0.8-10.3).
• Fat-free mass (1.2 kg; 95% CI, 0.4-2.0).
• Fat mass (1.0 kg; 95% CI, 0.3-1.7).
• Adiposity (2.6%; 95% CI, 0.1-5.2).

“This finding may suggest that fetal exposure to cannabis contributes to higher fasting glucose levels via a direct effect on the pancreatic β-cells. However, we cannot draw conclusions about β-cell response to glucose because we did not perform oral glucose tolerance tests,” the study authors wrote.

Notably, however, there was no relationship between BMI z-scores, BMI, or HOMA-IR and fasting insulin, the study team found.

Study limitations include the small sample size and lack of self-report data on cannabis use to differentiate between direct use and exposure to cannabis, Dr. Moore acknowledged.

Given the small sample size, the researchers were unable to look at dose-response, which future studies will focus on, Dr. Moore noted. Future efforts will also focus on comparing the effects of tetrahydrocannabinol (THC) and cannabidiol (CBD), Dr. Moore added.

“This is a relatively new field, so there’s still work to be done. This is just one study, and we need to study this more in other cohorts to confirm our findings,” she concluded.

Dr. Moore has reported no relevant financial relationships.

A new U.K. study shows no link between brain tumors and cell phone use, even among individuals who used their phones every day and/or had used them for over 10 years.

“These results support the accumulating evidence that mobile phone use under usual conditions does not increase brain tumor risk,” study author Kirstin Pirie, MSc, from the cancer epidemiology unit at Oxford (England) Population Health, said in a statement.

However, an important limitation of the study is that it involved only women who were middle-aged and older; these people generally use cell phones less than younger women or men, the authors noted. In this study’s cohort, mobile phone use was low, with only 18% of users talking on the phone for 30 minutes or more each week.

The results were published in the Journal of the National Cancer Institute.

This study is a “welcome addition to the body of knowledge looking at the risk from mobile phones, and specifically in relation to certain types of tumor genesis. It is a well-designed, prospective study that identifies no causal link,” commented Malcolm Sperrin from Oxford University Hospitals, who was not involved in the research.

“There is always a need for further research work, especially as phones, wireless, etc., become ubiquitous, but this study should allay many existing concerns,” he commented on the UK Science Media Centre.

Concerns about a cancer risk, particularly brain tumors, have been circulating for decades, and to date, there have been some 30 epidemiologic studies on this issue.

In 2011, the International Agency for Research on Cancer announced that cell phones are “possibly carcinogenic.” That conclusion was based largely on the results of the large INTERPHONE international case-control study and a series of Swedish studies led by Hardell Lennart, MD.

In the latest article, the U.K. researchers suggest that a “likely explanation for the previous positive results is that for a very slow growing tumor, there may be detection bias if cellular telephone users seek medical advice because of awareness of typical symptoms of acoustic neuroma, such as unilateral hearing problems, earlier than nonusers.

“The totality of human evidence, from observational studies, time trends, and bioassays, suggests little or no increase in the risk of cellular telephone users developing a brain tumor,” the U.K. researchers concluded.

Commenting on the U.K. study, Joachim Schüz, PhD, branch head of the section of environment and radiation at the IARC, noted that “mobile technologies are improving all the time, so that the more recent generations emit substantially lower output power.

“Nevertheless, given the lack of evidence for heavy users, advising mobile phone users to reduce unnecessary exposures remains a good precautionary approach,” Dr. Schuz said in a statement.
 

Details of U.K. study

The U.K. study was conducted by researchers from Oxford Population Health and IARC, who used data from the ongoing UK Million Women Study. This study began in 1996 and has recruited 1.3 million women born from 1935 to 1950 (which amounts to 1 in every 4 women) through the U.K. National Health Service Breast Screening Programme. These women complete regular postal questionnaires about sociodemographic, medical, and lifestyle factors.

Questions about cell phone use were completed by about 776,000 women in 2001 (when they were 50-65 years old). About half of these women also answered these questions about mobile phone use 10 years later, in 2011 (when they were aged 60-75).

The answers indicated that by 2011, the majority of women (75%) aged between 60 and 64 years used a mobile phone, while just under half of those aged between 75 and 79 years used one.

These women were then followed for an average of 14 years through linkage to their NHS records.

The researchers looked for any mention of brain tumors, including glioma, acoustic neuroma, meningioma, and pituitary gland tumors, as well as eye tumors.

During the 14 year follow-up period, 3,268 (0.42%) of the participants developed a brain tumor, but there was no significant difference in that risk between individuals who had never used a mobile phone and those who were mobile phone users. These included tumors in the temporal and parietal lobes, which are the most exposed areas of the brain.

There was also no difference in the risk of developing tumors between women who reported using a mobile phone daily, those who used them for at least 20 minutes a week, and those who had used a mobile phone for over 10 years.

In addition, among the individuals who did develop a tumor, the incidence of right- and left-sided tumors was similar among mobile phone users, even though mobile phone use tends to involve the right side considerably more than the left side, the researchers noted.

The study was funded by the UK Medical Research Council and Cancer Research UK.

Pointing a finger at COVID-19

The battle against COVID-19 is seemingly never ending. It’s been 2 years and still we struggle against the virus. But now, a new hero rises against the eternal menace, a powerful weapon against this scourge of humanity. And that weapon? Finger length.

Before you break out the sad trombone, hear us out. One of the big questions around COVID-19 is the role testosterone plays in its severity: Does low testosterone increase or decrease the odds of contracting severe COVID-19? To help answer that question, English researchers have published a study analyzing finger length ratios in both COVID-19 patients and a healthy control group. That seems random, but high testosterone in the womb leads to longer ring fingers in adulthood, while high estrogen leads to longer index fingers.

PxHere

According to the researchers, those who had significant left hand–right hand differences in the ratio between the second and fourth digits, as well as the third and fifth digits, were significantly more likely to have severe COVID-19 compared with those with more even ratios. Those with “feminized” short little fingers were also at risk. Those large ratio differences indicate low testosterone and high estrogen, which may explain why elderly men are at such high risk for severe COVID-19. Testosterone naturally falls off as men get older.

The results add credence to clinical trials looking to use testosterone-boosting drugs against COVID-19, the researchers said. It also gives credence to LOTME’s brand-new 12-step finger strength fitness routine and our branded finger weights. Now just $19.95! It’s the bargain of the century! Boost your testosterone naturally and protect yourself from COVID-19! We promise it’s not a scam.
 

Some emergencies need a superhero

Last week, we learned about the most boring person in the world. This week just happens to be opposite week, so we’re looking at a candidate for the most interesting person. Someone who can swoop down from the sky to save the injured and helpless. Someone who can go where helicopters fear to tread. Someone with jet engines for arms. Superhero-type stuff.

Richard Browning/Gravity Industries

The Great North Air Ambulance Service (GNAAS), a charitable organization located in the United Kingdom, recently announced that one of its members has completed training on the Gravity Industries Jet Suit. The suit “has two engines on each arm and a larger engine on the back [that] provide up to 317 pounds of thrust,” Interesting Engineering explained.

GNAAS is putting the suit into operation in England’s Lake District National Park, which includes mountainous terrain that is not very hospitable to helicopter landings. A paramedic using the suit can reach hikers stranded on mountainsides much faster than rescuers who have to run or hike from the nearest helicopter landing site.

“Everyone looks at the wow factor and the fact we are the world’s first jet suit paramedics, but for us, it’s about delivering patient care,” GNAAS’ Andy Mawson told Interesting Engineering. Sounds like superhero-speak to us.

So if you’re in the Lake District and have taken a bit of a tumble, you can call a superhero on your cell phone or you can use this to summon one.
 

Why we’re rejecting food as medicine

Humans have been using food to treat ailments much longer than we’ve had the advances of modern medicine. So why have we rejected its worth in our treatment processes? And what can be done to change that? The Center for Food as Medicine and the Hunter College NYC Food Policy Center just released a 335-page report that answers those questions.

phototake/ThinkStock

First, the why: Meals in health care settings are not medically designed to help with the specific needs of the patient. Produce-prescription and nutrition-incentive programs don’t have the government funds to fully support them. And a lot of medical schools don’t even require students to take a basic nutrition course. So there’s a lack of knowledge and a disconnect between health care providers and food as a resource.

Then there’s a lack of trust in the food industry and their validity. Social media uses food as a means of promoting “pseudoscientific alternative medicine” or spreading false info, pushing away legitimate providers. The food industry has had its fingers in food science studies and an almost mafia-esque chokehold on American dietary guidelines. No wonder food for medicine is getting the boot!

To change the situation, the report offers 10 key recommendations on how to advance the idea of incorporating food into medicine for treatment and prevention. They include boosting the funding for research, making hospitals more food-as-medicine focused, expanding federal programs, and improving public awareness on the role nutrition can play in medical treatment or prevention.

So maybe instead of rejecting food outright, we should be looking a little deeper at how we can use it to our advantage. Just a thought: Ice cream as an antidepressant.
 

Being rude is a good thing, apparently

If you’ve ever been called argumentative, stubborn, or unpleasant, then this LOTME is for you. Researchers at the University of Geneva have found that people who are more stubborn and hate to conform have brains that are more protected against Alzheimer’s disease. That type of personality seems to preserve the part of the brain that usually deteriorates as we grow older.

Piqsels

The original hypothesis that personality may have a protective effect against brain degeneration led the investigators to conduct cognitive and personality assessments of 65 elderly participants over a 5-year period. Researchers have been attempting to create vaccines to protect against Alzheimer’s disease, but these new findings offer a nonbiological way to help.

“For a long time, the brain is able to compensate by activating alternative networks; when the first clinical signs appear, however, it is unfortunately often too late. The identification of early biomarkers is therefore essential for … effective disease management,” lead author Panteleimon Giannakopoulos, MD, said in a Study Finds report.

You may be wondering how people with more agreeable and less confrontational personalities can seek help. Well, researchers are working on that, too. It’s a complex situation, but as always, we’re rooting for you, science!

At least now you can take solace in the fact that your elderly next-door neighbor who yells at you for stepping on his lawn is probably more protected against Alzheimer’s disease.

First, the why: Meals in health care settings are not medically designed to help with the specific needs of the patient. Produce-prescription and nutrition-incentive programs don’t have the government funds to fully support them. And a lot of medical schools don’t even require students to take a basic nutrition course. So there’s a lack of knowledge and a disconnect between health care providers and food as a resource.

Then there’s a lack of trust in the food industry and their validity. Social media uses food as a means of promoting “pseudoscientific alternative medicine” or spreading false info, pushing away legitimate providers. The food industry has had its fingers in food science studies and an almost mafia-esque chokehold on American dietary guidelines. No wonder food for medicine is getting the boot!

To change the situation, the report offers 10 key recommendations on how to advance the idea of incorporating food into medicine for treatment and prevention. They include boosting the funding for research, making hospitals more food-as-medicine focused, expanding federal programs, and improving public awareness on the role nutrition can play in medical treatment or prevention.

So maybe instead of rejecting food outright, we should be looking a little deeper at how we can use it to our advantage. Just a thought: Ice cream as an antidepressant.
 

Being rude is a good thing, apparently

If you’ve ever been called argumentative, stubborn, or unpleasant, then this LOTME is for you. Researchers at the University of Geneva have found that people who are more stubborn and hate to conform have brains that are more protected against Alzheimer’s disease. That type of personality seems to preserve the part of the brain that usually deteriorates as we grow older.

Piqsels

The original hypothesis that personality may have a protective effect against brain degeneration led the investigators to conduct cognitive and personality assessments of 65 elderly participants over a 5-year period. Researchers have been attempting to create vaccines to protect against Alzheimer’s disease, but these new findings offer a nonbiological way to help.

“For a long time, the brain is able to compensate by activating alternative networks; when the first clinical signs appear, however, it is unfortunately often too late. The identification of early biomarkers is therefore essential for … effective disease management,” lead author Panteleimon Giannakopoulos, MD, said in a Study Finds report.

You may be wondering how people with more agreeable and less confrontational personalities can seek help. Well, researchers are working on that, too. It’s a complex situation, but as always, we’re rooting for you, science!

At least now you can take solace in the fact that your elderly next-door neighbor who yells at you for stepping on his lawn is probably more protected against Alzheimer’s disease.

Pointing a finger at COVID-19

The battle against COVID-19 is seemingly never ending. It’s been 2 years and still we struggle against the virus. But now, a new hero rises against the eternal menace, a powerful weapon against this scourge of humanity. And that weapon? Finger length.

Before you break out the sad trombone, hear us out. One of the big questions around COVID-19 is the role testosterone plays in its severity: Does low testosterone increase or decrease the odds of contracting severe COVID-19? To help answer that question, English researchers have published a study analyzing finger length ratios in both COVID-19 patients and a healthy control group. That seems random, but high testosterone in the womb leads to longer ring fingers in adulthood, while high estrogen leads to longer index fingers.

According to the researchers, those who had significant left hand–right hand differences in the ratio between the second and fourth digits, as well as the third and fifth digits, were significantly more likely to have severe COVID-19 compared with those with more even ratios. Those with “feminized” short little fingers were also at risk. Those large ratio differences indicate low testosterone and high estrogen, which may explain why elderly men are at such high risk for severe COVID-19. Testosterone naturally falls off as men get older.

The results add credence to clinical trials looking to use testosterone-boosting drugs against COVID-19, the researchers said. It also gives credence to LOTME’s brand-new 12-step finger strength fitness routine and our branded finger weights. Now just $19.95! It’s the bargain of the century! Boost your testosterone naturally and protect yourself from COVID-19! We promise it’s not a scam.
 

Some emergencies need a superhero

Last week, we learned about the most boring person in the world. This week just happens to be opposite week, so we’re looking at a candidate for the most interesting person. Someone who can swoop down from the sky to save the injured and helpless. Someone who can go where helicopters fear to tread. Someone with jet engines for arms. Superhero-type stuff.

Richard Browning/Gravity Industries

The Great North Air Ambulance Service (GNAAS), a charitable organization located in the United Kingdom, recently announced that one of its members has completed training on the Gravity Industries Jet Suit. The suit “has two engines on each arm and a larger engine on the back [that] provide up to 317 pounds of thrust,” Interesting Engineering explained.

GNAAS is putting the suit into operation in England’s Lake District National Park, which includes mountainous terrain that is not very hospitable to helicopter landings. A paramedic using the suit can reach hikers stranded on mountainsides much faster than rescuers who have to run or hike from the nearest helicopter landing site.

“Everyone looks at the wow factor and the fact we are the world’s first jet suit paramedics, but for us, it’s about delivering patient care,” GNAAS’ Andy Mawson told Interesting Engineering. Sounds like superhero-speak to us.

So if you’re in the Lake District and have taken a bit of a tumble, you can call a superhero on your cell phone or you can use this to summon one.
 

Why we’re rejecting food as medicine

Humans have been using food to treat ailments much longer than we’ve had the advances of modern medicine. So why have we rejected its worth in our treatment processes? And what can be done to change that? The Center for Food as Medicine and the Hunter College NYC Food Policy Center just released a 335-page report that answers those questions.

The link between obesity and cancer has increasingly been emphasized in public health messages, but is the current message correct?

“Being overweight or having obesity increases your risk of getting cancer,” warns the U.S. Centers for Disease Control and Prevention. It warns that overweight/obesity is “linked with a higher risk of getting 13 types of cancer ... [which] make up 40% of all cancers diagnosed in the United States each year.”

But that message, which is also promulgated by many cancer organizations, is based on data from observational studies, which have many limitations.

A new study based on Mendelian randomization studies has come to a slightly different conclusion and has found a potential causal association with just six cancers.

In addition, it found an inverse relationship for breast cancer, in which early-life obesity was associated with a reduced risk of breast cancer, and the relationship with obesity was “complicated” for lung and prostate cancer.

The study, headed by Zhe Fang, MBBS, Harvard T. H. Chan School of Public Health, Boston, Mass., was published in the Journal of the National Cancer Institute

“For a seemingly straightforward question of whether excessive body fatness causes cancer, the answer may not be straightforward after all,” writes Song Yao, PhD, professor of oncology, Roswell Park Comprehensive Cancer Center, Buffalo, N.Y., in an accompanying editorial

“How to craft a simple public health message to convey the complexity and nuances of the relationships may be a challenge to be grappled with going forward,” he added.

In an interview, Dr. Yao said that it “really depends on what kind of message you want to get out.”

“If you want to talk about cancer overall, as one disease, we all know that a clear association with obesity does not exist,” he said. “It’s not that simple.”

“You really cannot say that obesity increases cancer risk overall,” he said.

For some cancers included in the study, Dr. Yao continued, it was “very clear that obesity increased the risk ... but for some other cancer types, we either don’t have enough data yet or the association is not as consistent.”

This, he said, is especially the case for prostate and lung cancer.

All of this indicates that there is a complex relationship between obesity and cancer risk, he maintains.

“We always think obesity is bad, not only for cancer but also for more common conditions, like hypertension, diabetes, and cardiovascular disease,” Dr. Yao noted. This points to the link between obesity and chronic inflammation, he added.

However, there are also other hypotheses, including synthesis of estrogen in adipose tissue, which may explain the link between obesity and breast cancer risk in older women.

However, in younger women, obesity protects against breast cancer, and “we really don’t know why,” Dr. Yao said.

The new study used Mendelian randomization to examine these relationships. This is a “new tool that we have developed over the past 20 years or so, largely because there is so much data coming from genome-wide association studies,” Dr. Yao explained.

It has “advantages” over other methods, including observational studies. One of its strengths is that it is “not impacted by reverse causality,” because genetic risk does not change over time.

However, he said, it is “quite straightforward to think that the genetics do not change, but at the same time, the environment we live in throughout our life course changes,” and the impact of genetic variants may be “washed out.”

How genetics influences cancer risk may therefore change over time, and it is a “dynamic process,” Dr. Yao commented.

In addition, this approach has its own limitations, he said, because it depends on how much of the variation in a given measure can be attributed to genetic factors.
 

New conclusions

In their study, Dr. Fang and colleagues reviewed 204 meta-analyses of 2,179 individual estimates from 507 cohort or case-control studies. They found “strong evidence” that supports the association between obesity and 11 cancers.

These are esophageal adenocarcinoma, multiple myeloma, and cancers of the gastric cardia, colon, rectum, biliary tract system, pancreas, breast, endometrium, ovary, and kidney.

They note, however, that the associations “may be causal for some malignancies” but that the co-occurrence of obesity with various cancer risk factors means that others may be “susceptible to potential confounding bias.”

To overcome some of these limitations, the team looked to Mendelian randomization studies that examined the association between genetic variants linked to body mass index (BMI), indicating lifetime risk of high BMI, and cancer risk for a range of cancer types.

These Mendelian randomization studies were then compared with the results of large-scale conventional observational studies, as well as with evidence in reports from the International Agency for Research on Cancer and the World Cancer Research Fund–American Institute of Cancer Research, which also include experimental studies.

The researchers say that, overall, the Mendelian randomization studies “further establish the causality of obesity” with six cancer types: colorectal, endometrial, ovarian, kidney, and pancreatic cancer, and esophageal adenocarcinoma.

In addition, these studies further establish the inverse relationship of early-life obesity with breast cancer.

However, the approach could not confirm a positive association between obesity and gallbladder and gastric cardia cancer, as well as multiple myeloma.

“This could be due to low power,” the team suggests, “and larger studies are required.”

With respect to lung cancer, the Mendelian randomization identified a positive association with obesity that supports the inverse association identified in observational studies, that is, that obesity may reduce the risk for lung cancer.

The researchers suggest this may reflect reverse causality related to the loss of lean body mass before diagnosis, as well as confounding by smoking.

For prostate cancer, the evidence was “conflicting” and “implies a complicated role of obesity,” Dr. Zhang and colleagues comment.

The link between obesity and lower prostate-specific antigen levels, they suggest, may result in a detection bias by masking the presence of prostate cancer, or it “could be biological” in origin, owing to reduced androgen levels.

For six cancer types for which a causal relationship with obesity could be established, the effect estimates from the Mendelian randomization studies were stronger than those seen in conventional studies, with the magnitude of risk ranging from 1.14-fold for early-life obesity and breast cancer to 1.37-fold for adult obesity and esophageal adenocarcinoma.

In another editorial accompanying the new study, Graham A. Colditz, MD, DrPH, from Washington University School of Medicine, St. Louis, underlined that childhood and adolescent obesity and their contribution to cancer risk need further attention.

“To reap the reward from past research, we must act to implement effective strategies to reduce childhood and adolescent adiposity, reduce excess weight gain in adult years, and maintain a healthy weight,” he writes.

“This will require us to change the way we live, but COVID-19 has shown we can make changes to how we live and work. Let us keep the changes we have already made, or take on new ones, that will cut our collective cancer toll,” he implores.

No funding for the study was described. Dr. Colditz is supported by the Breast Cancer Research Foundation. No other relevant financial relationships were described.

A prospective study that followed more than 110,000 men and women for more than 30 years suggests that eating two servings of avocado a week reduces the risk of developing cardiovascular disease (CVD).

Researchers also found that replacing half a serving of butter, cheese, bacon, or other animal product with an equivalent amount of avocado was associated with up to 22% lower risk for CVD events.

Among patients with diabetes, women are just as likely as men to suffer from sexual dysfunction, but their issues are overlooked, with the narrative focusing mainly on the impact of this issue on men, say experts.

Women with diabetes can experience reduced sexual desire, painful sex, reduced lubrication, and sexual distress, increasing the risk of depression, and such issues often go unnoticed despite treatments being available, said Kirsty Winkley, PhD, diabetes nurse and health psychologist, King’s College London.

There is also the “embarrassment factor” on the side of both the health care professional and the patient, she said in a session she chaired at the Diabetes UK Professional Conference 2022. Many women with diabetes “wouldn’t necessarily know” that their sexual dysfunction “is related to their diabetes,” she told this news organization.

For women, sexual health conversations are “often about contraception and pregnancy,” as well as menstrual disorders, genital infections, and hormone replacement therapy. “As health care professionals, you’re trained to focus on those things, and you’re not really considering there might be sexual dysfunction. If women aren’t aware that it’s related to diabetes, you’ve got the perfect situation where it goes under the radar.”

However, cochair Debbie Cooke, PhD, health psychologist at the University of Surrey in Guildford, explained that having psychotherapy embedded within the diabetes team and “integrated throughout the whole service” means that the problem can be identified and treatment offered.

The issue is that such integration is “very uncommon” and access needs to be improved, Dr. Cooke said in an interview.
 

Sexual dysfunction major predictor of depression in women

Jacqueline Fosbury, psychotherapy lead at Diabetes Care for You, Sussex Community NHS Foundation Trust, said that “intimate activity is clearly beneficial for emotional and physical health,” as it is associated with increased oxytocin release, the burning of calories, better immunity, and improved sleep.

Sexual dysfunction is common in people with diabetes, she noted. Poor glycemic control can “damage” blood vessels and nerves, causing reduced blood flow and loss of sensation in sexual organs.

A recent study led by Belgian researchers found that among more than 750 adults with diabetes, 36% of men and 33% of women reported sexual dysfunction.

Sexual dysfunction was more common in women with type 1 diabetes, at 36%, compared with 26% for those with type 2 diabetes. The most commonly reported issues were decreased sexual desire, lubrication problems, orgasmic dysfunction, and pain. Body image problems and fear of hypoglycemia also affect sexuality and intimacy, leading to “sexual distress.”

Moreover, Ms. Fosbury said female sexual dysfunction has been identified as a “major predictor” of depression, which in turn reduces libido.

Treatments for women can include lubricants, local estrogen, and medications that are prescribed off-label, such as sildenafil. The same is true of testosterone therapy, which can be used to boost libido.
 

Couples therapy?

Next, Trudy Hannington, a psychosexual therapist with Leger Clinic, Doncaster, U.K., talked about how to use an integrated approach to address sexuality overall in people with diabetes.

She said this should be seen in a biopsychosocial context, with emphasis on the couple, on sensation and communication, and sexual growth, as well as changes in daily routines.

There should be a move away from “penetrative sex,” Ms. Hannington said, with the goal being “enjoyment, not orgasm.” Pleasure should be facilitated and the opportunities for “performance pressure and/or anxiety” reduced.

She discussed the case of Marie, a 27-year-old woman with type 1 diabetes who had been referred with painful sex and vaginal dryness. Marie had “never experienced orgasm,” despite being in a same-sex relationship with Emily.

Marie’s treatment involved a sexual growth program, to which Emily was invited, as well as recommendations to use lubricants, vibrators, and to try sildenafil.
 

Prioritize women

Ms. Fosbury reiterated that, in men, sexual dysfunction is “readily identified as a complication of diabetes” and is described as “traumatic” and “crucial to well-being.” It is also seen as “easy to treat” with medication, such as that for erectile dysfunction.

It is therefore crucial to talk to women with diabetes about possible sexual dysfunction, and the scene must be set before the appointment to explain that the subject will be broached. In addition, handouts and leaflets should be available for patients in the clinic so they can read about female sexual health and to lower the stigma around discussing it.

“Cultural stereotypes diminish the importance of female sexuality and prevent us from providing equal consideration to the sexual difficulties of our patients,” she concluded.

Among patients with diabetes, women are just as likely as men to suffer from sexual dysfunction, but their issues are overlooked, with the narrative focusing mainly on the impact of this issue on men, say experts.

Women with diabetes can experience reduced sexual desire, painful sex, reduced lubrication, and sexual distress, increasing the risk of depression, and such issues often go unnoticed despite treatments being available, said Kirsty Winkley, PhD, diabetes nurse and health psychologist, King’s College London.

There is also the “embarrassment factor” on the side of both the health care professional and the patient, she said in a session she chaired at the Diabetes UK Professional Conference 2022. Many women with diabetes “wouldn’t necessarily know” that their sexual dysfunction “is related to their diabetes,” she told this news organization.

For women, sexual health conversations are “often about contraception and pregnancy,” as well as menstrual disorders, genital infections, and hormone replacement therapy. “As health care professionals, you’re trained to focus on those things, and you’re not really considering there might be sexual dysfunction. If women aren’t aware that it’s related to diabetes, you’ve got the perfect situation where it goes under the radar.”

However, cochair Debbie Cooke, PhD, health psychologist at the University of Surrey in Guildford, explained that having psychotherapy embedded within the diabetes team and “integrated throughout the whole service” means that the problem can be identified and treatment offered.

The issue is that such integration is “very uncommon” and access needs to be improved, Dr. Cooke said in an interview.
 

Sexual dysfunction major predictor of depression in women

Jacqueline Fosbury, psychotherapy lead at Diabetes Care for You, Sussex Community NHS Foundation Trust, said that “intimate activity is clearly beneficial for emotional and physical health,” as it is associated with increased oxytocin release, the burning of calories, better immunity, and improved sleep.

Sexual dysfunction is common in people with diabetes, she noted. Poor glycemic control can “damage” blood vessels and nerves, causing reduced blood flow and loss of sensation in sexual organs.

A recent study led by Belgian researchers found that among more than 750 adults with diabetes, 36% of men and 33% of women reported sexual dysfunction.

Sexual dysfunction was more common in women with type 1 diabetes, at 36%, compared with 26% for those with type 2 diabetes. The most commonly reported issues were decreased sexual desire, lubrication problems, orgasmic dysfunction, and pain. Body image problems and fear of hypoglycemia also affect sexuality and intimacy, leading to “sexual distress.”

Moreover, Ms. Fosbury said female sexual dysfunction has been identified as a “major predictor” of depression, which in turn reduces libido.

Treatments for women can include lubricants, local estrogen, and medications that are prescribed off-label, such as sildenafil. The same is true of testosterone therapy, which can be used to boost libido.
 

Couples therapy?

Next, Trudy Hannington, a psychosexual therapist with Leger Clinic, Doncaster, U.K., talked about how to use an integrated approach to address sexuality overall in people with diabetes.

She said this should be seen in a biopsychosocial context, with emphasis on the couple, on sensation and communication, and sexual growth, as well as changes in daily routines.

There should be a move away from “penetrative sex,” Ms. Hannington said, with the goal being “enjoyment, not orgasm.” Pleasure should be facilitated and the opportunities for “performance pressure and/or anxiety” reduced.

She discussed the case of Marie, a 27-year-old woman with type 1 diabetes who had been referred with painful sex and vaginal dryness. Marie had “never experienced orgasm,” despite being in a same-sex relationship with Emily.

Marie’s treatment involved a sexual growth program, to which Emily was invited, as well as recommendations to use lubricants, vibrators, and to try sildenafil.
 

Prioritize women

Dietary supplements that contain omega-3 fatty acids have been widely consumed for years. Researchers have been investigating the benefits of such preparations for cardiovascular, neurologic, and psychological conditions. A recently published study on omega-3 fatty acids and depression inspired neurologist Hans-Christoph Diener, MD, PhD, of the Institute for Epidemiology at the University Duisburg-Essen (Germany), to examine scientific publications concerning omega-3 fatty acids or fish-oil capsules in more detail.

Prevention of depression

Dr. Diener told the story of how he stumbled upon an interesting article in JAMA  in December 2021. It was about a placebo-controlled study that investigated whether omega-3 fatty acids can prevent incident depression.

As the study authors reported, treatment with omega-3 preparations in adults aged 50 years or older without clinically relevant symptoms of depression at study initiation was associated with a small but statistically significant increase in the risk for depression or clinically relevant symptoms of depression. There was no difference in mood scale value, however, over a median follow-up of 5.3 years. According to the study authors, these results did not support the administration of omega-3 preparations for the prevention of depression.

This study was, as Dr. Diener said, somewhat negative, but it did arouse his interest in questions such as what biological effects omega-3 fatty acids have and what is known “about this topic with regard to neurology,” he said. When reviewing the literature, he noticed that there “were association studies, i.e., studies that describe that the intake of omega-3 fatty acids may possibly be associated with a lower risk of certain diseases.”
 

Beginning with the Inuit

It all started “with observations of the Inuit [population] in Greenland and Alaska after World War II, because it was remarked upon that these people ate a lot of fish and seal meat and had a very low incidence of cardiovascular diseases.” Over the years, a large number of association studies have been published, which may have encouraged the assumption that omega-3 fatty acids have positive health effects on various conditions, such as cardiovascular diseases, hyperlipidemia, type 2 diabetes, various malignancies, cognitive impairments, Alzheimer’s disease, depression and anxiety disorders, heart failure, slipped disks, ADHD, symptoms of menopause, rheumatoid arthritis, asthma, periodontitis, epilepsy, chemotherapy tolerance, premenstrual syndrome, and nonalcoholic fatty liver disease.

Dr. Diener believes that the problem is that these are association studies. But association does not mean that there is a causal relationship.
 

Disappointing study results

On the contrary, the results from the randomized placebo-controlled studies are truly frustrating, according to the neurologist. A meta-analysis of the use of omega-3 fatty acids in cardiovascular diseases included 86 studies with over 162,000 patients. According to Dr. Diener, it did not reveal any benefit for overall and cardiovascular mortality, nor any benefit for the reduction of myocardial infarction and stroke.

The results did indicate a trend, however, for reduced mortality in coronary heart disease. Even so, the number needed to treat for this was 334, which means that 334 people would have to take omega-3 fatty acids for years to prevent one fatal cardiac event.

Aside from this study, Dr. Diener found six studies on Alzheimer’s disease and three studies on dementia with patient populations between 600 and 800. In these studies, too, a positive effect of omega-3 fatty acids could not be identified. Then he discovered another 31 placebo-controlled studies of omega-3 fatty acids for the treatment or prevention of depression and anxiety disorder. Despite including 50,000 patients, these studies also did not show any positive effect.

“I see a significant discrepancy between the promotion of omega-3 fatty acids, whether it’s on television, in the ‘yellow’ [journalism] press, or in advertisements, and the actual scientific evidence,” said Dr. Diener. “At least from a neurological perspective, there is no evidence that omega-3 fatty acids have any benefit. This is true for strokes, dementia, Alzheimer’s disease, depression, and anxiety disorders.”
 

Potential adverse effects

Omega-3 fatty acids also have potentially adverse effects. The VITAL Rhythm study recently provided evidence that, depending on the dose, preparations with omega-3 fatty acids may increase the risk for atrial fibrillation. As the authors wrote, the results do not support taking omega-3 fatty acids to prevent atrial fibrillation.

In 2019, the global market for omega-3 fatty acids reached a value of $4.1 billion. This value is expected to double by 2025, according to a comment by Gregory Curfman, MD, deputy editor of JAMA and lecturer in health care policy at Harvard Medical School, Boston.

As Dr. Curfman wrote, this impressive amount of expenditure shows how beloved these products are and how strongly many people believe that omega-3 fatty acids are beneficial for their health. It is therefore important to know the potential risks of such preparations. One such example for this would be the risk for atrial fibrillation.

According to Dr. Curfman, in the last 2 years, four randomized clinical studies have provided data on the risk for atrial fibrillation associated with omega-3 fatty acids. In the STRENGTH study, 13,078 high-risk patients with cardiovascular diseases were randomly assigned to one of two groups. The subjects received either a high dose (4 g/day) of a combination of eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) or corn oil. After a median of 42 months, there was no significant difference between the two groups in the primary composite cardiovascular endpoint, but more frequent atrial fibrillation in the omega-3 fatty acid group, compared with the corn oil group (2.2% vs. 1.3%; hazard ratio, 1.69; 95% confidence interval, 1.29-2.21; P < .001).

In the REDUCE-IT study, 8179 subjects were randomly assigned to a high dose (4 g/day, as in STRENGTH) of an omega-3 fatty acid preparation consisting of a purified EPA (icosapent ethyl) or mineral oil. After a median observation period of 4.9 years, icosapent ethyl was associated with a relative reduction of the primary composite cardiovascular endpoint by 25%, compared with mineral oil. As in the STRENGTH study, this study found that the risk for atrial fibrillation associated with omega-3 fatty acids, compared with mineral oil, was significantly higher (5.3% vs. 3.9%; P = .003).

In a third study (OMEMI), as Dr. Curfman reported, 1027 elderly patients who had recently had a myocardial infarction were randomly assigned to receive either a median dose of 1.8 g/day of omega-3 fatty acids (a combination of EPA and DHA) or corn oil. After 2 years, there was no significant difference between the two groups in primary composite cardiovascular endpoints, but 7.2% of the patients taking omega-3 fatty acids developed atrial fibrillation. In the corn oil group, this proportion was 4% (HR, 1.84; 95% CI, 0.98-3.45; P = .06).

The data from the four studies together indicate a potential dose-dependent risk for atrial fibrillation associated with omega-3 fatty acids, according to Dr. Curfman. At a dose of 4.0 g/day, there is a highly significant risk increase (almost double). With a median dose of 1.8 g/day, the risk increase (HR, 1.84) did not reach statistical significance. At a daily standard dose of 840 mg/day, an increase in risk could not be determined.

Dr. Curfman’s recommendation is that patients who take, or want to take, preparations with omega-3 fatty acids be informed of the potential development of arrhythmia at higher dosages. These patients also should undergo cardiological monitoring.

As they rolled me down the hallway to the OR, ceiling lights rhythmically passing above, I zoned out into a 1,000-mile stare. How did I get here? I started humming “Swing Low, Sweet Chariot,” praying for a miracle to happen. I thought back to my birth plan, meticulously crafted, a one-pager so that the no-nonsense labor and delivery nurses wouldn›t think me completely off my rocker. No C-section unless medically necessary. Those words laughed back at me – cackling, even. I’d planned out the whole birthing process and here we were, my team almost jogging me to the OR. I lay still, utterly gobsmacked and partially anesthetized.

If I squint my eyes and hallucinate just a bit, that is sort of what motherhood has been like.

It’s about knowing all the things that could go wrong and meeting the unplanned head-on. Motherhood has indeed been a whirlwind – so many physical, psychological, and emotional transformations. And to top it off, the added effort of giving birth in a pandemic. As an over-40 physician, you’d think I would have been better prepared.

I was, but in a sense, I was not. The knowledge, the wisdom, the experience of my medical training surrounded me, but even I panicked at times in the beginning: Am I feeding her correctly? Am I making enough food for her? Am I doing the best that I can for her? What more could I be doing for her?

Over time, I’ve learned to lighten up. Some. In those teachable moments with my daughter Gia, I’ve learned to not sugarcoat reality but encourage the hopeful. If Gia falls on the ground? “You’re okay, sweetie. Now get back up.” If Gia has a tantrum and starts hitting herself? “Honey, our hands are for hugs, not hurting ourselves. Let’s go play.” Eighty percent of motherhood right now is redirection and the other 20% is patience.

I remember this one time I was rushing out the door for work. After getting in the car with my keys, I realized I forgot my coffee back in the house. I left the car, went back in the house to grab the blessed joe, went back to the car, and couldn’t get in because it was locked. I panicked at that moment, went back inside the house, and found Gia playing with my extra key fob. My own daughter locked me out of my car. Of course, it wasn’t her fault. Deep breath and I offered her another kiss while simultaneously taking the key fob from her.

Before Gia could walk, she could climb the stairs in our home. Her father and I sometimes refer to her as “Lil Bamm-Bamm” because she is so strong. One day, Daddy was supposed to be watching her while Mommy was folding laundry upstairs. She was not allowed on the stairs, but what should I hear? Literally, the pitter-patter of little feet, running down the upstairs hallway. Her father had drifted off watching yet another episode of something Star Wars–related. My strong little girl made it up the stairs all by herself and Dad received a strong word. The Force was with me that day.

I would say that I feel like having a child ages you, but what does that really mean when you’re already old? I’ve become acutely aware of my lack of endurance, stamina, and bodily strength. My knees will creak when taking her upstairs to bed, an osseous dirge of a lullaby. Date nights become unintentionally less and less frequent. Friday night dress-up becomes Friday night dress-down. I’ve replaced stiletto heels with comfy sweats.

Once we put Gia down for the night, we are usually exhausted from the day, and the couch and TV are welcome respites. We exhale. As over-40 parents, we knew that having children late in life would bring its challenges. But I’d like to think that we are meeting them the best way that we can. Often I encourage my body to meet Gia at her eye level, see what she sees, play with her on her own terms, and match her energy. She absolutely loves it when I do this. I’m out of breath and my knees are sore by the end of our play session, but I wouldn’t have it any other way.

We are learning from each other. She has a bright and assertive personality, and I am protective of that innocence. Her innocence is without fear. I often wonder what she is thinking when I see her facial expressions. A side-eye, a fleeting giggle. Is she secretly contemplating the chronicity of the cosmos, or is it just gas? I look at her in stolen moments and still can’t believe that I grew a human inside me, and said human was extracted from me and is now walking around my house commanding her bidding. So surreal. The unromanticized, scientific ingredients that are at play from conception to delivery are nothing short of miraculous. And the miracles of parenting over 40 are present every day.

As they rolled me down the hallway to the OR, ceiling lights rhythmically passing above, I zoned out into a 1,000-mile stare. How did I get here? I started humming “Swing Low, Sweet Chariot,” praying for a miracle to happen. I thought back to my birth plan, meticulously crafted, a one-pager so that the no-nonsense labor and delivery nurses wouldn›t think me completely off my rocker. No C-section unless medically necessary. Those words laughed back at me – cackling, even. I’d planned out the whole birthing process and here we were, my team almost jogging me to the OR. I lay still, utterly gobsmacked and partially anesthetized.

If I squint my eyes and hallucinate just a bit, that is sort of what motherhood has been like.

Jen Gunter, MD, refuses to stay silent when she sees misleading claims about women’s health products.

In fact, the world’s most famous – and outspoken – ob.gyn. (as described by The Guardian), is on a social media mission to speak up whenever she sees companies or governments “prey on women’s health and vaginal shame.”

With nearly 400,000 followers, Dr. Gunter never shies away from a controversy.

Recently, she railed against vitamin and supplement maker Olly’s vaginal probiotic, taking the company to task for its product premise and objectionable ad copy.

This news organization caught up with the San Francisco–based doctor and author of two books, “The Vagina Bible” and “The Menopause Manifesto.” The following interview has been lightly edited for length and clarity.

Question: So these Olly capsules purport to be “Probiotics for Your Panty Hamster.” What was your reaction to this?

Answer: Seeing the word “panty hamsters” is so egregious. I’m so used to baseline vaginal opportunism, but this was just absolutely egregious and I had to call it out.

Question: What are vaginal probiotics anyway?

Answer: These are one of these big wellness scams where companies try to sell you on somehow hacking your microbiome by taking them. They’re not inexpensive, either, and can range in price from $30 to $150 per month, depending on how bespoke they are. And yet the data isn’t good. There is little to no evidence of the value of these probiotics except to shareholders.

Question: What’s one claim made in the Olly probiotic packaging that bothers you the most?

Answer: The product claims to balance the vaginal pH. To say that is a gross misunderstanding of the vaginal ecosystem. If that tagline is what you’re leading with, what else don’t you know?

Also, if these things worked, we’d recommend them. Vaginitis is complex and often misdiagnosed, and it’s easy for a company to be predatory and swoop in and say they have a product for you.

If I think your product for the vagina is awful and you have not studied it in at least one quality clinical trial (never mind company-funded or not), and your marketing displays a stunning ignorance about vaginal health, don’t approach me about your product. Really.

Question: When there’s a pop culture reference to, say, menstruation, you’re quick to weigh in.

Answer: I saw these viral messages from a boy mom (that’s what she called herself) where she wrote about being disgusted that there were mentions of periods in Turning Red, the animated movie.

Everything is here because of menstruation. If you didn’t menstruate, you wouldn’t have a kid, we wouldn’t have the person who had the intelligence to build the computer you’re spreading this message on. Menstruation is a vital part of human reproduction, and it’s far more complex than people think. For that reason alone, people should know about it.

Question: Do you ever get worried about being so “out there” on social media?

Answer: I have my stalkers I suppose, but the trolls don’t bother me. I don’t care if some whatever art dealer in New York thinks I have mental illness for promoting masks. That’s the best you’ve got? Honestly, this doesn’t even register with me. It’s like throwing a grain of sand at a car.

Question: You also got into an exchange with Dr. Leana Wen, CNN’s medical analyst, about mask wearing.

Answer: She obviously has a different opinion than I do. I think one of the biggest issues in the pandemic is the change in messaging and this idea that somehow people aren’t living their normal lives right now. I was sad to see her promote that concept.

This weekend I went out for lunch, I went furniture shopping, I went to the movies, I took a hike. My family and I wear masks everywhere. I fail to understand how wearing a mask means you’re not living a normal life when it’s clearly linked with the reduced spread of the virus.

Almost everything in medicine is about risk reduction. You can do things to lower your risk of heart disease. It’s not 100% guaranteed, but wouldn’t we want a lower risk of bad things? I’m going to keep wearing a mask forever!

Question: Do you wish more doctors were more vocal like you?

Answer: I wish more doctors would have conversations about health outside of the office in ways they’re comfortable with. Like, you’re at the hairdresser and you share information, or you share information with 15 of your Facebook friends. If you’re a doctor and post an article about COVID-19 and how it impacts the heart, your 15 friends are more likely to read that article than if your friend who’s a lawyer puts that up.

As doctors, I believe we can often influence people in big and small ways.
