As a gynecologist specializing in minimally invasive surgical techniques, what is your involvement in the process for diagnosing endometriosis?

Dr. Lager: At our multidisciplinary endometriosis center, we receive a range of referrals from excellent providers near San Francisco and beyond. As a result, patients will often have had extensive evaluations and multiple treatments. Nonetheless, it is important to take a thorough history, to gain an understanding of the progress of their disease, treatments they have taken and the results or side effects of those treatments, and the goals of the patient in order to guide next steps.

Reviewing previous operative reports, pathology, and surgical photos can also be helpful to guide next steps. Commonly, patients will present with dysmenorrhea, and depending on the severity of associated symptoms, such as dysuria, dyschezia, hematuria, or hematochezia, I may refer patients to our colleagues in urology or GI for further evaluation. 

Patients will often have previous imaging such as an ultrasound or CT to evaluate anatomic etiology of the pain, but those studies are often negative. Depending on their history, I may order additional imaging, such as an MRI pelvis, and consideration of vaginal or rectal gel. We have worked closely with our radiologists who have developed a specific endometriosis protocol for deeply infiltrative endometriosis and have a multidisciplinary review committee to discuss complex cases.

Although the gold standard for diagnosis of endometriosis is surgical, this leads to a delay in treatment of 7 to 12 years.[1] So, if a patient presents with symptoms of endometriosis, I will discuss the likely diagnosis and start treatment.

Are there specific techniques that you prefer in your standard practice once a clear diagnosis is determined?

Dr. Lager: As I mentioned, although endometriosis is a surgical diagnosis, there may be findings on imaging which will lead to a diagnosis of endometriosis, including endometriomas, uterosacral thickening, a “kissing ovary” appearance, or hematosalpinx for example.

I discuss a broad range of treatment options based on the patient’s goals, from least invasive treatments to definitive surgery. I discuss dietary changes, integrative medicine (we are fortunate to have an integrative medicine gynecologist here at UCSF Osher Center), and pain psychology.  Additionally, I review first-line hormonal management options such as: birth control pills, progestin-only pills, levenogestrol IUD, etonogestrel implant, and medroxyprogesterone acetate injection. In my practice, most patients have already tried initial treatment options, and are most interested in other options. I then review second-line options such as GnRH agonists, antagonists, danazol, and aromatase inhibitors. For patients that have had chronic pelvic pain, I also discuss peripheral and central sensitization, and overlapping diagnoses. Surgical management includes diagnostic laparoscopy and excision or ablation of endometriosis, hysterectomy, and oophorectomy.

Are there specific factors that you look for to help you decide whether surgical management is necessary?

Dr. Lager: There are several reasons why patients decide to proceed with surgical management.  First, some patients are reticent to start treatment, particularly if they have had negative experiences with hormonal medications and desire a definitive diagnosis. Other patients choose to proceed with surgery for fertility reasons, and others have severe symptoms that are not managed by medications.

The goal of surgery is to remove all visible endometriotic lesions, restore normal anatomy and for pathologic diagnosis if there is atypical characteristics of an endometrial mass. The pelvic exam and imaging can often be helpful surgical planning. If there is a deeply infiltrative lesion in the bowel or bladder, I consult my urology and colorectal colleagues for surgical planning.

Endometriotic lesions are heterogenous, and can include superficial peritoneal lesions, clear vesicular lesions, “powder burn lesions”, endometriomas, and deep infiltrative lesions. 

Additionally, I counsel patients on surgical options depending on the fertility desires. For patients with infertility and symptoms of endometriosis, primary surgery with excision or ablation increases pregnancy rates. One meta-analysis showed that operative laparoscopy improved live births and ongoing pregnancy rates.[2] This was found for the first laparoscopic surgery and not repeat surgery.

Can you talk a little bit more about some of the advancements and the controversies in surgical management, and how that impacts your practice or your treatment?

Dr. Lager: Controversy in surgical management includes excision versus ablation in surgical management of endometriosis. One randomized controlled trial showed an improvement with dyspareunia with excision versus ablation after 5 year follow up.[3] However, a recent meta-analysis from 2021 showed no difference in dysmenorrhea between excision and ablation.[4] I generally perform excision of endometriosis as it can provide a tissue for diagnosis and may allow for complete excision of a lesion that may have an underlying component not easily seen.

We also discussed some of the controversy related to fertility and endometriosis. Management of endometriomas in the face of desired fertility is unclear. Endometriomas that are >3 cm in diameter are associated with decreased anti-Mullerian hormone (AMH) levels, but ovarian cystectomy for endometriomas is also associated with decreased AMH levels. I will counsel patients regarding the risks and benefits of ovarian cystectomy and discuss with the reproductive endocrinologists if they recommend removal to improve oocyte retrieval.

Lastly, conservative versus definitive treatment is an important issue to discuss. Depending on a patient’s goals, conservative surgical management of endometriosis may be the most appropriate procedure. However, if a patient has multiple surgeries, does not desire to have children or has completed childbearing regardless of age and wants to decrease the risk of need for repeat surgery, I will discuss with patients that the risk of reoperation after hysterectomy versus conservative surgery is 8% vs 21% in 2 years and 59% vs 22% after 7 years, respectively.[5]  Additionally, the patient may have an overlapping gynecological condition, such as adenomyosis or fibroids, and desire surgical management for those conditions as well. Management ultimately will depend on shared decision making,

You mentioned overlapping diagnosis. What are the impacts and barriers related to misdiagnosis or overlapping diagnosis, and what is your approach to recognizing those signs and symptoms?

Dr. Lager: The classic symptoms of endometriosis can overlap with several medical conditions. In addition to gynecologic issues such as adenomyosis and fibroids that I mentioned previously, symptoms such as pelvic pain, bloating, and dysuria can be associated with gastrointestinal conditions, painful bladder syndrome, neurologic, and musculoskeletal pain conditions. This is complex because the overlapping diagnoses can lead to misdiagnosis, and delay in diagnosis and missing an associated diagnosis can lead to inadequate treatment.

I approach the possibility of overlapping diagnoses in consultation with my colleagues who may recommend further testing, such as endoscopy and colonoscopy. Depending on the diagnoses, several treatments can be started concomitantly to address the multifactorial components of pain.  For example, pelvic floor dysfunction related to pelvic pain can affect bowel habits, even without a diagnosis of IBS. Pelvic floor physical therapy can address one component of this. Similarly, even if we surgically or medically manage symptoms of endometriosis, the musculoskeletal pain can lead to persistent or worsening pain. The same goes for pain medicine and peripheral or central pain sensitization or neurological pain.

Was there anything else you’d like to share with your colleagues?

Dr. Lager: Endometriosis is a complex condition that requires a multifactorial approach that takes into consideration a patient’s goals. There is not a one-size fit for all patients with endometriosis due to all the issues we discussed. It will take time to address the varied components of pain and is an iterative process. Minimally invasive surgery has an important role in diagnosis and management of endometriosis but is one of several approaches to treat this complex condition. Thanks for taking the time to discuss this important condition that affects at least 10% of gynecological patients, and potentially more due to delayed and undiagnosed disease.

The first decline in COVID-19 cases among children since early April may have been holiday related, but the shortened week also brought news about vaccination for the youngest children.

The Food and Drug Administration has accepted Pfizer’s application for a COVID-19 vaccine for children under age 5, so vaccination could begin as early as June 21, according to White House COVID-19 response coordinator Ashish Jha, MD.

“We know that many, many parents are eager to vaccinate their youngest kids and it’s important to do this right,” Dr. Jha said at a White House press briefing June 2. “We expect that vaccinations will begin in earnest as early as June 21 and really roll on throughout that week.”

Decline may just be underreporting

Over on the incidence side of the pandemic, the total number of cases reported for the week of May 27 to June 2 was about 87,000, a drop of 22% from May 20-26 and the first decline after 7 straight weeks of increases. “Testing and reporting may have been affected by the holiday weekend [since] states may change their reporting schedules, which may cause irregularities in trends,” the American Academy of Pediatrics and the Children’s Hospital association said in their latest COVID report.

The decline in new cases was not spread uniformly across the four major regions of the United States. The count actually went up in the West for the week of May 27 to June 2, while the South saw the largest decline. The Midwest and Northeast, meanwhile, saw new cases drop for the second straight week, the AAP and CHA said.

The cumulative number of COVID-19 cases in children was up to 13.45 million as of June 2, with children representing 18.9% of all cases since the start of the pandemic, according to the two organizations. The Centers for Disease Control and Prevention reported figures of 13.14 million and 17.5% on June 6.

The AAP/CHA estimates, however, are based on state data that have become increasingly hard to obtain and subject to inconsistency. “Shortages of COVID-19 tests during surges and the increasing use of COVID-19 home tests likely affect the undercounting of COVID-19 cases,” they noted, and “at times when COVID-19 transmission is low, states might reduce the frequency information is updated.”
 

Vaccinations held steady over the holiday

The ongoing vaccination effort in children aged 5 years and older did not show a Memorial Day drop-off, as initial vaccinations held at 43,000 in 5- to 11-year-olds and at 27,000 in 12- to 17-year-olds for a second consecutive week. That number has ranged from 34,000 to 70,000 for the younger children and from 25,000 to 47,000 for the older group since mid-March, the AAP said in a separate weekly report.

Despite weekly vaccine initiations that have been roughly double those of the older children for months, the 5- to 11-year-olds are still only at 36.0% coverage with at least one dose, compared with 69.5% for the 12- to-17-year-olds. Full vaccination for the two age groups comes in at 29.3% and 59.6%, respectively, as of June 6, according to the CDC’s COVID Data Tracker.

Deaf babies and toddlers with developmental delays may benefit significantly from receiving cochlear implants over hearing aids.

A new study, published in the journal Pediatrics, pushes against the notion that children with low nonverbal cognition and adaptive functioning skills won’t improve if given cochlear implants. Some insurers cover hearing aids for children with developmental disorders but not the implants, which can cost between $60,000 and $100,000 per ear.

“We were surprised [by] the large magnitude of the improvements, not only in quality of life, but also in cognition, ability to function in daily living situations, and speech and language,” lead author John S. Oghalai, MD, of the University of Southern California, Los Angeles, told this news organization. “Remember, these are children with substantial developmental delays. Any improvements are incredibly important and meaningful.”

All children with severe hearing loss should be referred for cochlear implant evaluation, “regardless of the presence of other disabilities,” Dr. Oghalai said. “The younger this referral happens, the better the outcomes will be.”

Dr. Oghalai and his colleagues reviewed data from 204 children approximately 1-3 years old with hearing aids receiving treatment in Texas and California. Of these, 138 received a cochlear implant and had normal cognitive skills and social competence (referred to as adaptive behavior). Another 37 received a cochlear implant and also met criteria for early developmental impairment (EDI), defined by measures of nonverbal cognitive scores and adaptive functioning.

A third group of 29 children with EDI continued with hearing aids without a cochlear implant.

The children were evaluated annually for 1-5 years, with the average follow-up of 2 years. At baseline, no significant differences were noted between the children with EDI who received implants and those who did not on cognition, language, auditory skills, or measures of parental or child stress.

Overall, children who received implants scored higher on cognitive and social measures than those who continued using hearing aids.

Compared with children with EDI who received implants, children without EDI who received implants had significantly higher developmental scores by the study’s end (P ≤ .001), whereas children with EDI who did not receive implants had significantly lower scores (P ≤ .04).

Children who received implants, and their parents, also experienced less stress than those who did not receive the devices, according to the researchers.

Dr. Oghalai and colleagues also measured developmental trajectories for each cohort. Children without delays who received implants had the best outcomes, but those with EDI who received implants had better outcomes than those with EDI and hearing aids.
 

Findings ‘overdue’

“This study is overdue,” Howard Francis, MD, chair of the department of head and neck surgery & communication sciences at Duke University, Durham, N.C., told this news organization.

Dr. Francis called the new research “reasonably powered and designed,” and said it “documents benefits in the cognitive, language, and patient-child relationship domains” in children who received cochlear implants “compared to children with similar levels of developmental delay whose hearing loss was treated using hearing aids.”  

However, “larger studies will be needed to account for potential effects of older age at intervention in the hearing aid group,” he said. Socioeconomic effects are a topic for future research as well, Dr. Francis added.

The researchers initially wanted to perform a controlled clinical trial. However, by the time they secured funding, health insurance policy had changed to cover cochlear implants for children without EDI because of demonstrated benefits shown in studies.

They also were unable to determine the reasons for families’ decisions to choose implants or hearing aids and were unable to assess the impact of insurance on the choice of implantation. But they did find that families with insurers who would cover implants often did choose the devices. Children were also followed for an average of 2 years, so long-term outcomes are unknown.  

Despite these limitations, the results support the value of cochlear implantation in children with disabilities and developmental delays, and it should be discussed with parents, the researchers concluded.

“Cochlear implants are just a tool; they do not provide speech and language,” Dr. Oghalai said. “Any child with severe hearing loss requires significant therapy and education via sign language, auditory-verbal therapy, or both. Making the decision about what type of therapy to do is personal, and it depends upon the family and the options that are available to them in their community.”

The study was funded by the National Institutes of Health. The researchers and Dr. Francis have disclosed no relevant financial relationships.

Deaf babies and toddlers with developmental delays may benefit significantly from receiving cochlear implants over hearing aids.

A new study, published in the journal Pediatrics, pushes against the notion that children with low nonverbal cognition and adaptive functioning skills won’t improve if given cochlear implants. Some insurers cover hearing aids for children with developmental disorders but not the implants, which can cost between $60,000 and $100,000 per ear.

“We were surprised [by] the large magnitude of the improvements, not only in quality of life, but also in cognition, ability to function in daily living situations, and speech and language,” lead author John S. Oghalai, MD, of the University of Southern California, Los Angeles, told this news organization. “Remember, these are children with substantial developmental delays. Any improvements are incredibly important and meaningful.”

All children with severe hearing loss should be referred for cochlear implant evaluation, “regardless of the presence of other disabilities,” Dr. Oghalai said. “The younger this referral happens, the better the outcomes will be.”

Dr. Oghalai and his colleagues reviewed data from 204 children approximately 1-3 years old with hearing aids receiving treatment in Texas and California. Of these, 138 received a cochlear implant and had normal cognitive skills and social competence (referred to as adaptive behavior). Another 37 received a cochlear implant and also met criteria for early developmental impairment (EDI), defined by measures of nonverbal cognitive scores and adaptive functioning.

A third group of 29 children with EDI continued with hearing aids without a cochlear implant.

The children were evaluated annually for 1-5 years, with the average follow-up of 2 years. At baseline, no significant differences were noted between the children with EDI who received implants and those who did not on cognition, language, auditory skills, or measures of parental or child stress.

Overall, children who received implants scored higher on cognitive and social measures than those who continued using hearing aids.

Compared with children with EDI who received implants, children without EDI who received implants had significantly higher developmental scores by the study’s end (P ≤ .001), whereas children with EDI who did not receive implants had significantly lower scores (P ≤ .04).

Children who received implants, and their parents, also experienced less stress than those who did not receive the devices, according to the researchers.

Dr. Oghalai and colleagues also measured developmental trajectories for each cohort. Children without delays who received implants had the best outcomes, but those with EDI who received implants had better outcomes than those with EDI and hearing aids.

A new imaging study hopes to make diagnosing endometriosis quicker, more accurate and reduce the need for invasive surgery.

In October 2020 the All Party Parliamentary Group on Endometriosis published a report that included within its recommendations “a commitment to drive down diagnosis times” for women with the condition. On average, it takes around 8 years for a woman to get a diagnosis of endometriosis, a figure, said the authors of the report, that had “not improved in the last decade.”

Indeed, in its report the APPG said that it was seeking a commitment from Governments in all four nations to reduce average diagnosis times with “targets of 4 years or less by 2025, and a year or less by 2030.”
 

Surgery often needed for endometriosis diagnosis

Endometriosis affects 1 in 10 women between puberty and menopause – 1.5 million in the United Kingdom – often results in multiple general practitioner and accident and emergency department visits, multiple scans, and often laparoscopic surgery to confirm the diagnosis, as there is currently no simple diagnostic test for the condition. One of the main reasons for the delay in diagnosis is the lack of noninvasive tests capable of detecting all endometriosis subtypes – ovarian, superficial, and deep disease.

Now, experts at the Endometriosis CaRe Centre and Nuffield Department of Women’s and Reproductive Health, University of Oxford (England), in collaboration with British life sciences company Serac Healthcare, hope to establish a faster process for diagnosing endometriosis.

Christian Becker, codirector of the Endometriosis CaRe Centre in Oxford, and a study lead, said: “There is an urgent unmet clinical need for a noninvasive marker to identify or rule out endometriosis as it is such a very common disease affecting more than 190 million women worldwide.”

In the study, researchers will investigate whether a 20-minute imaging scan can detect the most common types of endometriosis, which currently require surgery to diagnose. In turn, they hope that earlier diagnosis of the condition will allow women to seek appropriate treatment sooner. They will use an experimental imaging marker – ^99mTc-maraciclatide – that binds to areas of inflammation and that can be used in endometriosis to visualize the disease on a scan. The imaging marker has already been used for detecting inflammation in conditions such as rheumatoid arthritis.

Between 2 and 7 days before planned surgery for suspected endometriosis, participants will be invited for an imaging scan, and the team will compare the suspected locations of disease detected on the scan with those seen during surgery to confirm whether this imaging test could be an effective noninvasive method of detecting all endometriosis subtypes.
 

Doctor visits and repeated investigations reduced

The researchers commented that the potential strengths of the scan lie in the way the imaging marker binds to areas of inflammation, which may allow doctors to distinguish between new and old lesions and detect endometriosis in areas not easily seen during surgery, such as the lung.

They added that the development of a 20-minute imaging test would reduce the need for repeated visits to doctors, for repeated investigations, and for invasive surgery to obtain a diagnosis. This would ultimately “reduce the time taken to confirm or exclude endometriosis,” they pointed out.

Following the publication of the APPG report in October 2020 the group’s then chair, the late Sir David Amess, said: “Without investment in research, a reduction in diagnosis time, and appropriate NHS pathways, those with endometriosis will continue to face huge barriers in accessing the appropriate support at the right time.”

Krina Zondervan, head of department at the Nuffield Department of Women’s and Reproductive Health, University of Oxford, and a study lead, said: “This study highlights that close collaborations between academics, clinicians and industry are important to combine and accelerate discovery and innovation in addressing high-priority areas in women’s health such as endometriosis.”

David Hail, CEO of Serac Healthcare, said: “We are excited about the potential of ^99mTc-maraciclatide to diagnose endometriosis noninvasively and delighted to be working with the internationally renowned team at Oxford on this important first study.”

Social engagement such as participation in community or school-based activities may mitigate psychosis risk in susceptible youth living in disadvantaged communities, new research suggests.

A study of more than 170 young participants showed reduced hippocampal volume in those living in poor neighborhoods who had low social engagement versus their peers with greater community engagement.

“These findings demonstrate the importance of considering broader environmental influences and indices of social engagement when conceptualizing adversity and potential interventions for individuals at clinical high risk for psychosis,” co-investigator Benson Ku, MD, a postdoctoral fellow and psychiatry resident at Emory University School of Medicine, Atlanta, told this news organization.

Emory University

A personal connection

It’s well known that growing up in low-income housing is associated with lower hippocampal volume and an increased risk for schizophrenia, said Dr. Ku.

“The inverse relationship between poverty and hippocampal gray matter volume has [also] been shown to be mediated by social stress, which can include things like lack of parental caregiving and stressful life events,” he added.

Dr. Ku himself grew up in a socioeconomically disadvantaged family in Queens, New York, and he said he had initially performed poorly in school. His early experiences have helped inform his clinical and research interests in the social determinants of mental health.

“I found community support in the Boys’ Club of New York and a local Magic Shop near where I lived, which helped me thrive and become the successful man I am today. I have also heard from my patients how their living conditions and neighborhood have significantly impacted their mental health,” Dr. Ku said.

“A more in-depth understanding of the social determinants of mental health has helped build rapport and empathy with my patients,” he added.

To explore the association between neighborhood poverty, social engagement, and hippocampal volume in youth at high risk for psychosis, the researchers analyzed data from the North American Prodrome Longitudinal Study Phase 2, a multisite consortium.

The researchers recruited and followed up with help-seeking adolescents and young adults from diverse neighborhoods. The analysis included 174 youth, ages 12-33 years, at high clinical risk for psychosis.

Hippocampal volume was assessed using structural MRI. Neighborhood poverty was defined as the percentage of residents with an annual income below the poverty level in the past year.

Social engagement was derived from the desirable events subscale items of the Life Events Scale. These activities included involvement in a church or synagogue; participation in a club, neighborhood, or other organization; taking a vacation; engaging in a hobby, sport, craft, or recreational activity; acquiring a pet; or making new friends.
 

Lower hippocampal volume

Results showed neighborhood poverty was associated with reduced hippocampal volume, even after controlling for several confounders, including race/ethnicity, family history of mental illnesses, household poverty, educational level, and stressful life events.

Among the 77 participants with lower social engagement, which was defined as three or fewer social activities, neighborhood poverty was associated with reduced hippocampal volume.

However, in the 97 participants who reported greater social engagement, which was defined as four or more social activities, neighborhood poverty was not significantly associated with hippocampal volume.

“It is possible that social engagement may mitigate the deleterious effects of neighborhood poverty on brain morphology, which may inform interventions offered to individuals from disadvantaged neighborhoods,” Dr. Ku said.

“If replication of the relationships between neighborhood poverty, hippocampal volume, and social engagement is established in other populations in longitudinal studies, then targeted interventions at the community level and increased social engagement may potentially play a major role in disease prevention among at-risk youth,” he said.

Dr. Ku noted social engagement might look different in urban versus rural settings.

“In urban areas, it might mean friends, clubs, neighborhood organizations, etc. In rural areas, it might mean family, pets, crafts, etc. The level of social engagement may also depend on neighborhood characteristics, and more research would be needed to better understand how geographic area characteristics – remote, rural, urban – affects social engagement,” he said.
 

Interesting, innovative

Nagy Youssef, MD, PhD, director of clinical research and professor of psychiatry, Ohio State University College of Medicine, Columbus, said the study suggests “social engagement may reduce the negative effect of poverty in this population, and if replicated in a larger study, could assist and be a part of the early intervention and prevention in psychosis.”

Ohio State University

Overall, “this is an interesting and innovative study that has important medical and social implications and is a good step toward helping us understand these relationships and mitigate and prevent negative consequences, as best as possible, in this population,” said Dr. Youssef, who was not part of the research.

The analysis was supported by a grant from the National Institute of Mental Health to the North American Prodrome Longitudinal Study. Dr. Ku and Dr. Youssef report no relevant financial relationships.

Overall, “this is an interesting and innovative study that has important medical and social implications and is a good step toward helping us understand these relationships and mitigate and prevent negative consequences, as best as possible, in this population,” said Dr. Youssef, who was not part of the research.

The analysis was supported by a grant from the National Institute of Mental Health to the North American Prodrome Longitudinal Study. Dr. Ku and Dr. Youssef report no relevant financial relationships.

Spending more time doing light-intensity activities and less time being sedentary was associated with a reduced risk for first stroke in a population-based study of middle aged and older adults.

The study also found relatively short periods of moderate to vigorous exercise were associated with reduced stroke risk.

“Our results suggest there are a number of ways to reduce stroke risk simply by moving about,” said lead author Steven P. Hooker, PhD, San Diego State University. “This could be with short periods of moderate to vigorous activity each day, longer periods of light activity, or just sedentary for shorter periods of time. All these things can make a difference.”

Dr. Hooker explained that, while it has been found previously that moderate to vigorous exercise reduces stroke risk, this study gives more information on light-intensity activities and sedentary behavior and the risk of stroke.

“Our results suggest that you don’t have to be a chronic exerciser to reduce stroke risk. Replacing sedentary time with light-intensity activity will be beneficial. Just go for a short walk, get up from your desk and move around the house at regular intervals. That can help to reduce stroke risk,” Dr. Hooker said.  

“Our message is basically to sit less and move more,” he added.  

The study was published online in JAMA Network Open.

The study involved 7,607 U.S. individuals without a history of stroke, with oversampling from the southeastern “Stroke Belt,” who were participating in the REGARDS cohort study.

The participants wore an accelerometer to measure physical activity and sedentary behavior for 7 consecutive days. The mean age of the individuals was 63 years; 54% were female, 32% were Black.

Over a mean follow-up of 7.4 years, 286 incident stroke cases occurred.

Results showed that increased levels of physical activity were associated with reduced risk of stroke.

For moderate to vigorous activity, compared with participants in the lowest tertile, those in the highest tertile of total daily time in moderate to vigorous activity had a 43% lower risk of stroke.

In the current study, the amount of moderate to vigorous activity associated with a significant reduction in stroke risk was approximately 25 minutes per day (3 hours per week).

Dr. Hooker noted that moderate to vigorous activity included things such as brisk walking, jogging, bike riding, swimming, or playing tennis or soccer. “Doing such activities for just 25 minutes per day reduced risk of stroke by 43%. This is very doable. Just commuting to work by bicycle would cover you here,” he said.

In terms of light-intensity activity, individuals who did 4-5 hours of light activities each day had a 26% reduced risk for first stroke, compared with those doing less than 3 hours of such light activities.

Dr. Hooker explained that examples of light activity included household chores, such as vacuuming, washing dishes, or going for a gentle stroll. “These activities do not require heaving breathing, increased heart rate or breaking into a sweat. They are activities of daily living and relatively easy to engage in.”

But he pointed out that the 4-5 hours of light activity every day linked to a reduction in stroke risk may be more difficult to achieve than the 25 minutes of moderate to vigorous activity, saying: “You have to have some intentionality here.”
 

Long bouts of sedentary time are harmful

The study also showed that sedentary time was associated with a higher risk for stroke.

The authors noted that time spent in sedentary behavior is of interest because most adults spend most of their awake time being physically inactive.

They report that participants in the highest tertile of sedentary time (more than 13 hours/day) exhibited a 44% increase in risk of stroke, compared with those in the lowest tertile (less than 11 hours/day), and the association remained significant when adjusted for several covariates, including moderate to vigorous activity.

“Even when controlling for the amount of other physical activity, sedentary behavior is still highly associated with risk of stroke. So even if you are active, long bouts of sedentary behavior are harmful,” Dr. Hooker commented.

They also found that longer bouts of sedentary time (more than 17 minutes at a time) were associated with a 54% higher risk of stroke than shorter bouts (less than 8 minutes).

“This suggests that breaking up periods of sedentary behavior into shorter bouts would be beneficial,” Dr. Hooker said.

“If you are going to spend the evening on the couch watching television, try to stand up and walk around every few minutes. Same for if you are sitting at a computer all day – try having a standing workstation, or at least take regular breaks to walk around,” he added.

This research was supported by grants from the National Institute of Neurological Disorders and Stroke and the National Institute on Aging. Additional funding was provided by an unrestricted grant from the Coca-Cola Company. The authors report no disclosures.

Doctors were significantly less likely to order colorectal cancer screening with the at-home test Cologuard (Exact Sciences) for Black patients and were more likely to order the test for Asian patients, new evidence reveals.

Investigators retrospectively studied 557,156 patients in the Mayo Clinic health system from 2012 to 2022. They found that Cologuard was ordered for 8.7% of Black patients, compared to 11.9% of White patients and 13.1% of Asian patients.

Both minority groups were less likely than White patients to undergo a follow-up colonoscopy within 1 year of Cologuard testing. Cologuard tests the stool for blood and DNA markers associated with colorectal cancer.

Although the researchers did not examine the reasons driving the disparities, lead investigator Ahmed Ouni, MD, told this news organization that “it could be patient preferences ... or there could be some bias as providers ourselves in how we present the data to patients.”

Dr. Ouni presented the findings on May 22 at the annual Digestive Disease Week^® (DDW), held in person in San Diego and virtually.
 

Breakdown by physician specialty

“We looked at the specialty of physicians ordering these because we wanted to see where the disparity was coming from, if there was a disparity,” said Dr. Ouni, a gastroenterologist at Mayo Clinic, Jacksonville, Florida.

Just over half (51%) of the patients received care from family medicine physicians, 27% received care from internists, and 22% were seen by gastroenterologists.

Family physicians ordered Cologuard testing for 8.7% of Black patients, compared with 16.1% of White patients, a significant difference (P < .001). Internists ordered the test for 10.5% of Black patients and 11.1% of White patients (P <  .001). Gastroenterologists ordered Cologuard screening for 2.4% of Black patients and 3.2% of White patients (P = .009).

Gastroenterologists were 47% more likely to order Cologuard for Asian patients, and internists were 16% more likely to order it for this population than for White patients. However, the findings were not statistically significant for the overall cohort of Asian patients when the researchers adjusted for age and sex (P = 0.52).

Black patients were 25% less likely to have a follow-up colonoscopy within 1 year of undergoing a Cologuard test (odds ratio, 0.75; 95% confidence interval, 0.60-0.94), and Asian patients were 35% less likely (OR, 0.65; 95% CI, 0.52-0.82).
 

Ongoing and future research

Of the total study population, only 2.9% self-identified as Black; according to the 2020 U.S. Census, 12.4% of the population of the United States are Black persons.

When asked about the relatively low proportion of Black persons in the study, Dr. Ouni replied that the investigators are partnering with a Black physician group in the Jacksonville, Fla., area to expand the study to a more diverse population.

Additional plans include assessing how many positive Cologuard test results led to follow-up colonoscopies.

The investigators are also working with family physicians at the Mayo Clinic to examine how physicians explain colorectal cancer screening options to patients and are studying patient preferences regarding screening options, which include Cologuard, fecal immunochemical test (FIT)/fecal occult blood testing, CT colonography, and colonoscopy.

“We’re analyzing the data by ZIP code to see if this could be related to finances,” Dr. Ouni added. “So, if you’re Black or White and more financially impoverished, how does that affect how you view Cologuard and colorectal cancer screening?”
 

Some unanswered questions

“Overall this study supports other studies of a disparity in colorectal cancer screening for African Americans,” John M. Carethers, MD, told this news organization when asked to comment. “This is known for FIT and colonoscopy, and Cologuard, which is a genetic test in addition to FIT, appears to be in that same realm.”

“Noninvasive tests will have a role to reach populations who may not readily have access to colonoscopy,” said Dr. Carethers, John G. Searle Professor and chair of the department of internal medicine and professor of human genetics at the University of Michigan, Ann Arbor. “The key here is if the test is positive, it needs to be followed up with a colonoscopy.”

Dr. Carethers added that the study raises some unanswered questions; for example, does the cost difference between testing options make a difference?

“FIT is under $20, but Cologuard is generally $300 or more,” he said. What percentage of the study population were offered other options, such as FIT? How does insurance status affect screening in different populations?”

“The findings should be taken in context of what other screening options were offered to or elected by patients,” agreed Gregory S. Cooper, MD, professor of medicine and population and quantitative health sciences at Case Western Reserve University and a gastroenterologist at University Hospitals Cleveland Medical Center.

According to guidelines, patients can be offered a menu of options, including FIT, colonoscopy, and Cologuard, Dr. Cooper said in an interview.

“If more African Americans elected colonoscopy, for example, the findings may balance out,” said Dr. Cooper, who was not affiliated with the study. “It would also be of interest to know if the racial differences changed over time. With the pandemic, the use of noninvasive options, such as Cologuard, have increased.”

“I will note that specifically for colonoscopy in the United States, the disparity gap had been closing from about 15% to 18% 20 years ago to about 3% in 2020 pre-COVID,” Dr. Carethers added. “I am fearful that COVID may have led to a widening of that gap again as we get more data.”

“It is important that noninvasive tests for screening be a part of the portfolio of offerings to patients, as about 35% of eligible at-risk persons who need to be screened are not screened in the United States,” Dr. Carethers said.

The study was not industry sponsored. Dr. Ouni and Dr. Carethers report no relevant financial relationships. Dr. Cooper has received consulting fees from Exact Sciences.

The effectiveness of hormonal contraceptives, including the pill and mini-pill, may be compromised by sugammadex, a drug widely used in anesthesia for reversing neuromuscular blockade induced by rocuronium or vecuronium.

Yet women are not routinely informed that the drug may make their contraception less effective, delegates at Euroanaesthesia, the annual meeting of the European Society of Anaesthesiology and Intensive Care in Milan were told.

New research presented at the meeting supports the authors’ experience that “robust methods for identifying at-risk patients and informing them of the associated risk of contraceptive failures is not common practice across anesthetic departments within the United Kingdom, and likely further afield.”

This is according to a survey of almost 150 anesthetic professionals, including consultants, junior doctors, and physician assistants, working at University College London Hospitals NHS Foundation Trust.

Dr. Neha Passi, Dr. Matt Oliver, and colleagues at the trust’s department of anesthesiology sent out a seven-question survey to their 150 colleagues and received 82 responses, 94% of which claimed awareness of the risk of contraceptive failure with sugammadex. However, 70% of the respondents admitted that they do not routinely discuss this with patients who have received the drug.
 

Risk with all forms of hormonal contraceptive

Yet current guidance is to inform women of child-bearing age that they have received the drug and, because of increased risk of contraceptive failure, advise those taking oral hormonal contraceptives to follow the missed pill advice in the leaflet that comes with their contraceptives. It also counsels that clinicians should advise women using other types of hormonal contraceptive to use an additional nonhormonal means of contraception for 7 days.

The study authors also carried out a retrospective audit of sugammadex use in the trust and reported that during the 6 weeks covered by the audit, 234 patients were administered sugammadex of whom 65 (28%) were women of childbearing age. Of these, 17 had a medical history that meant they weren’t at risk of pregnancy, but the other 48 should have received advice on the risks of contraceptive failure – however there was no record in the medical notes of such advice having been given for any of the at-risk 48 women.

While sugammadex is the only anesthetic drug known to have this effect, it is recognized to interact with progesterone and so may reduce the effectiveness of hormonal contraceptives, including the progesterone-only pill, combined pill, vaginal rings, implants, and intrauterine devices.

Dr. Passi said: “It is concerning that we are so seldom informing patients of the risk of contraceptive failure following sugammadex use.

“Use of sugammadex is expected to rise as it becomes cheaper in the future, and ensuring that women receiving this medicine are aware it may increase their risk of unwanted pregnancy must be a priority.”

She added: “It is important to note, however, that most patients receiving an anesthetic do not need a muscle relaxant and that sugammadex is one of several drugs available to reverse muscle relaxation.”

Dr. Oliver said: “We only studied one hospital trust but we expect the results to be similar in elsewhere in the U.K.”

In response to their findings, the study’s authors have created patient information leaflets and letters and programmed the trust’s electronic patient record system to identify “at-risk” patients and deliver electronic prompts to the anesthetists caring for them in the perioperative period.

The effectiveness of hormonal contraceptives, including the pill and mini-pill, may be compromised by sugammadex, a drug widely used in anesthesia for reversing neuromuscular blockade induced by rocuronium or vecuronium.

Yet women are not routinely informed that the drug may make their contraception less effective, delegates at Euroanaesthesia, the annual meeting of the European Society of Anaesthesiology and Intensive Care in Milan were told.

Increases in use of the antipsychotic risperidone (Risperdal) are associated with small dose-related increases in both weight and blood cholesterol levels, new research suggests.

Investigators analyzed 1-year data for more than 400 patients who were taking risperidone and/or its metabolite paliperidone (Invega). Results showed increments of 1 mg of risperidone-equivalent doses were associated with an increase of 0.25% of weight within a year of follow-up.

“Although our findings report a positive and statistically significant dose-dependence of weight gain and cholesterol, both total and LDL [cholesterol], the size of the predicted changes of metabolic effects is clinically nonrelevant,” lead author Marianna Piras, PharmD, Centre for Psychiatric Neuroscience, Lausanne (Switzerland) University Hospital, said in an interview.

“Therefore, dose lowering would not have a beneficial effect on attenuating weight gain or cholesterol increases and could lead to psychiatric decompensation,” said Ms. Piras, who is also a PhD candidate in the unit of pharmacogenetics and clinical psychopharmacology at the University of Lausanne.

However, she added that because dose increments could increase risk for significant weight gain in the first month of treatment – the dose can be increased typically in a range of 1-10 grams – and strong dose increments could contribute to metabolic worsening over time, “risperidone minimum effective doses should be preferred.”

The findings were published online in the Journal of Clinical Psychiatry.
 

‘Serious public health issue’

Compared with the general population, patients with mental illness present with a greater prevalence of metabolic disorders. In addition, several psychotropic medications, including antipsychotics, can induce metabolic alterations such as weight gain, the investigators noted.

Antipsychotic-induced metabolic adverse effects “constitute a serious public health issue” because they are risk factors for cardiovascular diseases such as obesity and/or dyslipidemia, “which have been associated with a 10-year reduced life expectancy in the psychiatric population,” Ms. Piras said.

“The dose-dependence of metabolic adverse effects is a debated subject that needs to be assessed for each psychotropic drug known to induce weight gain,” she added.

Several previous studies have examined whether there is a dose-related effect of antipsychotics on metabolic parameters, “with some results suggesting that [weight gain] seems to develop even when low off-label doses are prescribed,” Ms. Piras noted.

She and her colleagues had already studied dose-related metabolic effects of quetiapine (Seroquel) and olanzapine (Zyprexa).

Risperidone is an antipsychotic with a “medium to high metabolic risk profile,” the researchers note, and few studies have examined the impact of risperidone on metabolic parameters other than weight gain.

For the current analysis, they analyzed data from a longitudinal study that included 438 patients (mean age, 40.7 years; 50.7% men) who started treatment with risperidone and/or paliperidone between 2007 and 2018.

The participants had diagnoses of schizophrenia, schizoaffective disorder, bipolar disorder, depression, “other,” or “unknown.”

Clinical follow-up periods were up to a year, but were no shorter than 3 weeks. The investigators also assessed the data at different time intervals at 1, 3, 6, and 12 months “to appreciate the evolution of the metabolic parameters.”

In addition, they collected demographic and clinical information, such as comorbidities, and measured patients’ weight, height, waist circumference, blood pressure, plasma glucose, and lipids at baseline and at 1, 3, and 12 months and then annually. Weight, waist circumference, and BP were also assessed at 2 and 6 months.

Doses of paliperidone were converted into risperidone-equivalent doses.
 

Significant weight gain over time

The mean duration of follow-up for the participants, of whom 374 were being treated with risperidone and 64 with paliperidone, was 153 days. Close to half (48.2%) were taking other psychotropic medications known to be associated with some degree of metabolic risk.

Patients were divided into two cohorts based on their daily dose intake (DDI): less than 3 mg/day (n = 201) and at least 3 mg/day (n = 237).

In the overall cohort, a “significant effect of time on weight change was found for each time point,” the investigators reported.

Small increases, big changes

Commenting on the study, Erika Nurmi, MD, PhD, associate professor in the department of psychiatry and biobehavioral sciences at the Semel Institute for Neuroscience, University of California, Los Angeles, said the study is “unique in the field.”

It “leverages real-world data from a large patient registry to ask a long-unanswered question: Are weight and metabolic adverse effects proportional to dose? Big data approaches like these are very powerful, given the large number of participants that can be included,” said Dr. Nurmi, who was not involved with the research.

However, she cautioned, the “biggest drawback [is that] these data are by nature much more complex and prone to confounding effects.”

In this case, a “critical confounder” for the study was that the majority of individuals taking higher risperidone doses were also taking other drugs known to cause weight gain, whereas the majority of those on lower risperidone doses were not. “This difference may explain the dose relationship observed,” she said.

Because real-world, big data are “valuable but also messy, conclusions drawn from them must be interpreted with caution,” Dr. Nurmi said.

She added that it is generally wise to use the lowest effective dose possible.

“Clinicians should appreciate that even small doses of antipsychotics can cause big changes in weight. Risks and benefits of medications must be carefully considered in clinical practice,” Dr. Nurmi said.

The research was funded in part by the Swiss National Research Foundation. Piras reports no relevant financial relationships. The other investigators’ disclosures are listed in the original article. Dr. Nurmi reported no relevant financial relationships, but she is an unpaid member of the Tourette Association of America’s medical advisory board and of the Myriad Genetics scientific advisory board.

Although it has been used as an ingredient in sunscreens and other personal care products since the 1980s, benzophenone-3 (BP-3) or oxybenzone has emerged in recent years as a significant environmental and health contaminant. DiNardo and Downs point out that BP-3 has been linked to contact and photocontact allergies in humans and implicated as a potential endocrine disruptor. They add that it can yield deleterious by-products when reacting with chlorine in swimming pools and wastewater treatment plants and can cause additional side effects in humans who ingest fish.¹ This column will focus on recent studies, mainly on the role of benzophenones in sunscreen agents that pose considerable risks to waterways and marine life, with concomitant effects on the food chain.

Environmental effects of BPs and legislative responses

Various UV filters, including BP-3, octinoxate, octocrylene, and ethylhexyl salicylate, are thought to pose considerable peril to the marine environment.^2,3 In particular, BP-3 has been demonstrated to provoke coral reef bleaching in vitro, leading to ossification and deforming DNA in the larval stage.^3,4

According to a 2018 report, BP-3 is believed to be present in approximately two thirds of organic sunscreens used in the United States.³ In addition, several studies have revealed that detectable levels of organic sunscreen ingredients, including BP-3, have been identified in coastal waters around the globe, including Hawaii and the U.S. Virgin Islands.^4-8

M Swiet Productions/Moment/Getty Images

A surfeit of tourists has been blamed in part, given that an estimated 25% of applied sunscreen is eliminated within 20 minutes of entering the water and thought to release about 4,000-6,000 tons/year into the surrounding coral reefs.^9,10 In Hawaii in particular, sewage contamination of the waterways has resulted from wastewater treatment facilities ill-equipped to filter out organic substances such as BP-3 and octinoxate.^10,11 In light of such circumstances, the use of sunscreens containing BP-3 and octinoxate have been restricted in Hawaii, particularly in proximity to beaches, since Jan. 1, 2021, because of their apparent environmental impact.¹⁰

The exposure of coral to these compounds is believed to result in bleaching because of impaired membrane integrity and photosynthetic pigment loss in the zooxanthellae that coral releases.^9,10 Coral and the algae zooxanthellae have a symbiotic relationship, Siller et al. explain, with the coral delivering protection and components essential for photosynthesis and the algae ultimately serving as nutrients for the coral.¹⁰ Stress endured by coral is believed to cause algae to detach, rendering coral more vulnerable to disease and less viable overall.¹⁰

In 2016, Downs et al. showed that four out of five sampled locations had detectable levels of BP-3 (100 pp trillion) with a fifth tested site measured at 19.2 pp billion.⁴

In 2019, Sirois acknowledges the problem of coral bleaching around the world but speculates that banning sunscreen ingredients for this purpose will delude people that such a measure will reverse the decline of coral and may lead to the unintended consequence of lower use of sunscreens. Sirois adds that a more comprehensive investigation of the multiple causes of coral reef bleaching is warranted, as are deeper examinations of studies using higher concentrations of sunscreen ingredients in artificial conditions.¹²

In the same year, Raffa et al. discussed the impending ban in Hawaii of the two sunscreen ingredients (BP-3 and octinoxate) to help preserve coral reefs. In so doing, they detailed the natural and human-induced harm to coral reefs, including pollution, fishing practices, overall impact of global climate change, and alterations in ocean temperature and chemistry. The implication is that sunscreen ingredients, which help prevent sun damage in users, are not the only causes of harm to coral reefs. Nevertheless, they point out that concentration estimates and mechanism studies buttress the argument that sunscreen ingredients contribute to coral bleaching. Still, the ban in Hawaii is thought to be a trend. Opponents of the ban are concerned that human skin cancers will rise in such circumstances. Alternative chemical sunscreens are being investigated, and physical sunscreens have emerged as the go-to recommendation.¹³

Notably, oxybenzone has been virtually replaced in the European Union with other UV filters with broad-spectrum action, but the majority of such filters have not yet been approved for use in the United States by the Food and Drug Administration.³

Food chain implications

BP-3 and other UV filters have been investigated for their effects on fish and mammals. Schneider and Lim illustrate that BP-3 is among the frequently used organic UV filters (along with 4-methylbenzylidene camphor, octocrylene, and octinoxate [ethylhexyl methoxycinnamate]) found in most water sources in the world, as well as multiple fish species.2 Cod liver in Norway, for instance, was found to contain octocrylene in 80% of cod, with BP-3 identified in 50% of the sample. BP-3 and octinoxate were also found in white fish.2,14 In laboratory studies, BP-3 in particular has been found in high concentrations in rainbow trout and Japanese rice fish (medaka), causing reduced egg production and hatchlings in females and increased vitellogenin protein production in males, suggesting potential feminization.^2,15

Schneider and Lim note that standard wastewater treatment approaches cannot address this issue and the presence of such contaminants in fish can pose dangerous ramifications in the food chain. They assert that, despite relatively low concentrations in the fish, bioaccumulation and biomagnification present the potential for chemicals accumulating over time and becoming more deleterious as such ingredients travel up the food chain. As higher-chain organisms absorb higher concentrations of the chemicals not broken down in the lower-chain organisms, though, there have not yet been reports of adverse effects of biomagnification in humans.²

BP-3 has been found by Brausch and Rand to have bioaccumulated in fish at higher levels than the ambient water, however.^1,2,16 Schneider and Lim present these issues as relevant to the sun protection discussion, while advocating for dermatologists to continue to counsel wise sun-protective behaviors.²

Conclusion

While calls for additional research are necessary and encouraging, I think human, and likely environmental, health would be better protected by the use of inorganic sunscreens in general and near or in coastal waterways. In light of legislative actions, in particular, it is important for dermatologists to intervene to ensure that patients do not engage in riskier behaviors in the sun in areas facing imminent organic sunscreen bans.

Although it has been used as an ingredient in sunscreens and other personal care products since the 1980s, benzophenone-3 (BP-3) or oxybenzone has emerged in recent years as a significant environmental and health contaminant. DiNardo and Downs point out that BP-3 has been linked to contact and photocontact allergies in humans and implicated as a potential endocrine disruptor. They add that it can yield deleterious by-products when reacting with chlorine in swimming pools and wastewater treatment plants and can cause additional side effects in humans who ingest fish.¹ This column will focus on recent studies, mainly on the role of benzophenones in sunscreen agents that pose considerable risks to waterways and marine life, with concomitant effects on the food chain.

Environmental effects of BPs and legislative responses

Various UV filters, including BP-3, octinoxate, octocrylene, and ethylhexyl salicylate, are thought to pose considerable peril to the marine environment.^2,3 In particular, BP-3 has been demonstrated to provoke coral reef bleaching in vitro, leading to ossification and deforming DNA in the larval stage.^3,4

According to a 2018 report, BP-3 is believed to be present in approximately two thirds of organic sunscreens used in the United States.³ In addition, several studies have revealed that detectable levels of organic sunscreen ingredients, including BP-3, have been identified in coastal waters around the globe, including Hawaii and the U.S. Virgin Islands.^4-8

A surfeit of tourists has been blamed in part, given that an estimated 25% of applied sunscreen is eliminated within 20 minutes of entering the water and thought to release about 4,000-6,000 tons/year into the surrounding coral reefs.^9,10 In Hawaii in particular, sewage contamination of the waterways has resulted from wastewater treatment facilities ill-equipped to filter out organic substances such as BP-3 and octinoxate.^10,11 In light of such circumstances, the use of sunscreens containing BP-3 and octinoxate have been restricted in Hawaii, particularly in proximity to beaches, since Jan. 1, 2021, because of their apparent environmental impact.¹⁰

The exposure of coral to these compounds is believed to result in bleaching because of impaired membrane integrity and photosynthetic pigment loss in the zooxanthellae that coral releases.^9,10 Coral and the algae zooxanthellae have a symbiotic relationship, Siller et al. explain, with the coral delivering protection and components essential for photosynthesis and the algae ultimately serving as nutrients for the coral.¹⁰ Stress endured by coral is believed to cause algae to detach, rendering coral more vulnerable to disease and less viable overall.¹⁰

In 2016, Downs et al. showed that four out of five sampled locations had detectable levels of BP-3 (100 pp trillion) with a fifth tested site measured at 19.2 pp billion.⁴

In 2019, Sirois acknowledges the problem of coral bleaching around the world but speculates that banning sunscreen ingredients for this purpose will delude people that such a measure will reverse the decline of coral and may lead to the unintended consequence of lower use of sunscreens. Sirois adds that a more comprehensive investigation of the multiple causes of coral reef bleaching is warranted, as are deeper examinations of studies using higher concentrations of sunscreen ingredients in artificial conditions.¹²

In the same year, Raffa et al. discussed the impending ban in Hawaii of the two sunscreen ingredients (BP-3 and octinoxate) to help preserve coral reefs. In so doing, they detailed the natural and human-induced harm to coral reefs, including pollution, fishing practices, overall impact of global climate change, and alterations in ocean temperature and chemistry. The implication is that sunscreen ingredients, which help prevent sun damage in users, are not the only causes of harm to coral reefs. Nevertheless, they point out that concentration estimates and mechanism studies buttress the argument that sunscreen ingredients contribute to coral bleaching. Still, the ban in Hawaii is thought to be a trend. Opponents of the ban are concerned that human skin cancers will rise in such circumstances. Alternative chemical sunscreens are being investigated, and physical sunscreens have emerged as the go-to recommendation.¹³

Notably, oxybenzone has been virtually replaced in the European Union with other UV filters with broad-spectrum action, but the majority of such filters have not yet been approved for use in the United States by the Food and Drug Administration.³

Food chain implications

BP-3 and other UV filters have been investigated for their effects on fish and mammals. Schneider and Lim illustrate that BP-3 is among the frequently used organic UV filters (along with 4-methylbenzylidene camphor, octocrylene, and octinoxate [ethylhexyl methoxycinnamate]) found in most water sources in the world, as well as multiple fish species.2 Cod liver in Norway, for instance, was found to contain octocrylene in 80% of cod, with BP-3 identified in 50% of the sample. BP-3 and octinoxate were also found in white fish.2,14 In laboratory studies, BP-3 in particular has been found in high concentrations in rainbow trout and Japanese rice fish (medaka), causing reduced egg production and hatchlings in females and increased vitellogenin protein production in males, suggesting potential feminization.^2,15

Schneider and Lim note that standard wastewater treatment approaches cannot address this issue and the presence of such contaminants in fish can pose dangerous ramifications in the food chain. They assert that, despite relatively low concentrations in the fish, bioaccumulation and biomagnification present the potential for chemicals accumulating over time and becoming more deleterious as such ingredients travel up the food chain. As higher-chain organisms absorb higher concentrations of the chemicals not broken down in the lower-chain organisms, though, there have not yet been reports of adverse effects of biomagnification in humans.²

BP-3 has been found by Brausch and Rand to have bioaccumulated in fish at higher levels than the ambient water, however.^1,2,16 Schneider and Lim present these issues as relevant to the sun protection discussion, while advocating for dermatologists to continue to counsel wise sun-protective behaviors.²

Conclusion

While calls for additional research are necessary and encouraging, I think human, and likely environmental, health would be better protected by the use of inorganic sunscreens in general and near or in coastal waterways. In light of legislative actions, in particular, it is important for dermatologists to intervene to ensure that patients do not engage in riskier behaviors in the sun in areas facing imminent organic sunscreen bans.
