A history of concussion can have serious long-term mental health implications for women, even years after giving birth, according to a new study.

Researchers looked at all people who delivered babies in Ontario, Canada, and found that those with a predelivery history of concussion were 25% more likely to have a serious mental illness up to 14 years after giving birth than those with no history of concussion.

The findings indicate the need for early identification and screening of women with a history of concussion, as well as ongoing, long-term supports to prevent adverse psychiatric outcomes, wrote the authors.

“I played a lot of sports growing up, and I definitely would not have thought about how a concussion could affect childbearing or parenting,” author Samantha Krueger, RM, MSc, told this news organization. She completed the research as part of her studies at the University of Toronto, Ontario.

The data were published on November 4 in The Journal of Clinical Psychiatry.
 

Implications for Prevention

“Birthing people, and women in general, are an often-overlooked population in the scientific literature on traumatic brain injury, including concussion. There is a potential interplay between concussion history and the challenges of being a new parent (such as labor and birth, lack of sleep, and increased noise) that make this an important population to study,” said Krueger.

The researchers conducted a population-based cohort study of all women who gave birth in Ontario between 2007 and 2017. Follow-up continued until 2021. The primary outcome was severe maternal mental illness, which was defined as a psychiatric emergency department visit, psychiatric hospital admission, or self-harm or suicide in the 14 years after delivery.

The researchers identified 18,064 women with a predelivery history of concussion and 736,689 women without a history of concussion during the study period. Women with a predelivery history of concussion were more likely than those without such a history to live in a rural area and have a history of assault or mental illness.

Overall, 11.3% (n = 2033) of the women with a predelivery history of concussion developed severe maternal mental illness (14.7 per 1000 person-years), compared with 6.8% (n = 49,928) of the women without a predelivery history of concussion (7.9 per 1000 person-years).

The adjusted hazard ratio (aHR) was 1.25. The association was strongest in women who had a predelivery history of concussion but no history of mental illness (aHR, 1.33).

“We hope to increase awareness of the seriousness of having a concussion, even when it is considered a mild head injury,” Krueger said. “The results have important implications for concussion prevention measures for young people and for the provision of postpartum supports (such as mental health and other social supports like sleep relief) to mitigate the risk of serious mental illness outcomes in birthing people with a history of concussion.”

Healthcare providers, including maternity care providers, should be asking about concussion history and providing mental health screening and supports to clients and their families to detect mental illness before a serious outcome occurs, Krueger added.

“Maternity care providers can help birthing people and their families set up supports for after the baby is born and teach families about mental health symptoms to look out for. It’s also important that providers be certain that their care is trauma informed to avoid triggering a trauma response when providing care,” she said.
 

 

 

Area of Concern

“This research is novel and highlights an area of major concern,” Simon Sherry, PhD, professor of psychology and neuroscience at Dalhousie University in Halifax, Nova Scotia, Canada, told this news organization. Sherry did not participate in the study.

“Postpartum depression occurs in approximately 10%-25% of mothers, but it is likely that many more cases go undiagnosed. It is attributed to hormonal changes, genetic predisposition, and environmental factors, and while previous depression or mental illness is frequently considered a risk factor, traumatic brain injuries or concussions usually are not,” Sherry said.

“Mothers are already an at-risk population for mental illness, as illustrated by the high rates of postpartum depression, and so are people with a history of concussion or traumatic brain injury. What sets this study apart is that it shows the heightened risk for women with the combination of those two distinct risk factors. Identifying these risk factors is essential to providing preventive care. If care providers know a patient is at increased risk when starting a pregnancy, then they will likely catch warning signs earlier,” he said.

“Additionally, as the article suggests, maternal mental health often is not studied beyond the first postpartum year,” Sherry said.

“Mental health struggles during the first postpartum year have largely been normalized as part of the transition into parenthood, but mental health issues among parents later in life are less accepted. After birth, so much emphasis is moved from the parent to the child. Parents rightly prioritize their children, but our job as care providers is to ensure we are also prioritizing them. The prolonged period of this study helps illustrate how important the practice of prioritizing mothers’ mental health is,” he added.

The study was supported by ICES, which is funded by an annual grant from the Ontario Ministry of Health and the Ministry of Long-Term Care. The Canadian Institutes of Health Research also supported the study. Krueger is supported by a Canadian Institutes of Health Research Canada Graduate Scholarship Masters Award. Sherry reported no relevant financial relationships.

4 Simple Hacks to Get Paid for Lifestyle Medicine

Article Type

Thu, 11/07/2024 - 10:16

This transcript has been edited for clarity. 

As primary care doctors, lifestyle medicine is supposed to be a pillar of our practice. Per the evidence, lifestyle medicine can prevent up to 80% of chronic disease. It’s a real irony, then, that it’s the thing we’re least likely to be paid to do.

Thankfully, though, there are a few hacks to help you keep your patients healthy and yourself financially healthy at the same time.

No. 1: Be as accurate in your coding as possible. We all know working on things like sleep, exercise, and diet with patients takes time, so bill for it. With time-based billing, in particular, you can account for both the time spent in face-to-face encounters and the time spent afterward on documentation and care coordination. Make sure to capture that.

No. 2: Try group visits on for size. Group visit models are great for lifestyle medicine. They give you the flexibility to include longer conversations and deeper lessons on a range of subjects while still getting paid for what you do. Want to host a cooking class? Group visit. Want to bring in a personal trainer or hold a dance class or exercise dance class? Group visit. Meditation, yoga, or even a sleep hygiene class? Group visit. 

While there are a few tricks to getting paid for group visits, they’re the same things, such as documenting time and the various parts of the visit, that are key to getting paid for regular visits. They have the bonus of fighting burnout and making your own practice more meaningful as well.

No. 3: Think about joining a value-based care arrangement. While only accounting for 10% of the market right now, value-based care (VBC) is growing rapidly, and it’s easy to see why. By trading quality for the hamster wheel of billing widgets, physicians are freed up to think more about how best to take care of patients, including incorporating more lifestyle medicine. Some VBC models even have their own electronic medical records, freeing you from outdated structures when it comes to documenting patient visits.

No. 4: direct primary care. Direct primary care cuts out the middlemen of payers, letting patients pay physician practices directly for their own care. Like VBC, it opens up possibilities for practicing better medicine, including lifestyle medicine. In addition, it’s often very affordable, with a family of four often paying around $80 a month for a membership for the entire family. It’s a win-win for the doctor and the patient. 

Lifestyle medicine is a great way to improve both your patients’ and your own well-being. With a few flexes, it can improve your wallet’s well-being, too.

Treating Obesity May Reduce Pelvic Organ Prolapse Risk

Article Type
Changed
Thu, 11/07/2024 - 10:12

 

TOPLINE:

People with central obesity (CO), characterized by excess fat around the abdomen, are at a greater risk for pelvic organ prolapse (POP), particularly those who are younger than 60 years or without a history of hysterectomy. Also, women who have overweight but do not have CO are at greater risk.

METHODOLOGY:

  • Researchers conducted a prospective cohort study to estimate the association between CO and general obesity and the risk for POP in individuals using the UK Biobank.
  • A total of 251,143 participants (median age, 57 years) without preexisting POP were included, of whom 60.9% were postmenopausal and 17.2% had undergone hysterectomy before enrollment.
  • Participants were followed for a median duration of 13.8 years, and POP cases were identified using International Classification of Diseases, 10th Revision (ICD-10) codes.
  • Waist circumference, height, and body weight were measured at enrollment for the calculation of waist/height ratio and body mass index (BMI); CO was defined as a waist/height ratio ≥ 0.5.
  • The relative risk of POP for the various combinations of waist/height ratio and BMI was evaluated against the reference group (waist/height ratio < 0.5; BMI < 25) using Cox proportional hazards models.

TAKEAWAY:

  • During the follow-up period, 9781 cases of POP were identified, of which 71.2% occurred in a single pelvic compartment.
  • Around 21.7% of all POP cases were attributable to CO; 2% were attributable to being overweight without CO.
  • The risk for POP was 48% higher in individuals with CO regardless of BMI (hazard ratio [HR], 1.48; 95% CI, 1.41-1.56) and 23% higher in those who had overweight without CO (HR, 1.23; 95% CI, 1.14-1.34).
  • The association between POP and CO was further strengthened in individuals who were younger than 60 years and those without a history of hysterectomy.

IN PRACTICE:

“We found that waist/height ratio combined with BMI could help differentiate individuals with varying risks of prolapse more accurately. Among individuals within the same BMI category, waist/height ratio can vary, with those having a higher ratio generally facing a greater risk of POP, compared with those with a normal ratio. Therefore, they should not be grouped together based solely on a single measure of obesity. In addition, this combination can help identify more individuals at high risk for POP, compared with using either alone,” the study authors wrote.
 

SOURCE:

This study was led by Keyi Si, PhD, of Tongji University in Shanghai, China, and was published online in Obstetrics & Gynecology.

LIMITATIONS:

Differences in healthcare-seeking behavior could have biased the association between obesity and risk for POP, as individuals with obesity may have been less likely to notice or report symptoms of POP. The diagnosis of POP was according to ICD-10 codes rather than physical examination, which may have affected accuracy. Other limitations included missing data on delivery mode and history of constipation.

DISCLOSURES:

This study was supported by grants from the National Natural Science Foundation of China, the Science and Technology Commission of Shanghai Municipality, the Shanghai Hospital Development Center, and the Shanghai First Maternity and Infant Hospital. The authors reported no conflicts of interest.

  • The risk for POP was 48% higher in individuals with CO regardless of BMI (hazard ratio [HR], 1.48; 95% CI, 1.41-1.56) and 23% higher in those who had overweight without CO (HR, 1.23; 95% CI, 1.14-1.34).
  • The association between POP and CO was further strengthened in individuals who were younger than 60 years and those without a history of hysterectomy.

IN PRACTICE:

“We found that waist/height ratio combined with BMI could help differentiate individuals with varying risks of prolapse more accurately. Among individuals within the same BMI category, waist/height ratio can vary, with those having a higher ratio generally facing a greater risk of POP, compared with those with a normal ratio. Therefore, they should not be grouped together based solely on a single measure of obesity. In addition, this combination can help identify more individuals at high risk for POP, compared with using either alone,” the study authors wrote.
 

SOURCE:

This study was led by Keyi Si, PhD, of Tongji University in Shanghai, China, and was published online in Obstetrics & Gynecology.

LIMITATIONS:

Differences in healthcare-seeking behavior could have biased the association between obesity and risk for POP, as individuals with obesity may have been less likely to notice or report symptoms of POP. The diagnosis of POP was according to ICD-10 codes rather than physical examination, which may have affected accuracy. Other limitations included missing data on delivery mode and history of constipation.

DISCLOSURES:

This study was supported by grants from the National Natural Science Foundation of China, the Science and Technology Commission of Shanghai Municipality, the Shanghai Hospital Development Center, and the Shanghai First Maternity and Infant Hospital. The authors reported no conflicts of interest.

Knowledge Gaps About Obesity Medicine Seen in Primary Care

Article Type
Changed
Thu, 11/07/2024 - 10:07

— Despite the prevalence of obesity in primary care, there appear to be major knowledge gaps among providers regarding obesity management, new research suggests. 

Anonymous surveys of 96 primary care providers at a Boston, Massachusetts, safety-net hospital revealed that participants had limited understanding of criteria for prescribing antiobesity medications (AOM), and expressed discomfort in prescribing AOMs because of knowledge concerns, especially for non–glucagon-like peptide 1 (GLP-1) receptor agonists. One third reported that they didn’t prescribe AOMs, and rates of referral for bariatric surgery were also low. 

The findings were presented at the Obesity Society’s annual Obesity Week meeting by Alejandro Campos, MD, a third-year resident in the section of internal medicine, Boston Medical Center, and the Department of Medicine, Boston University. 

“I think it comes down to education. ... Not only training primary care physicians or residents about criteria and pathophysiology, but also stigma. Perceptions need to be addressed from the start of training in the healthcare field,” Campos told this news organization in an interview.

During his presentation, Campos noted this is the first such study in the setting of a safety-net hospital, which cares for lower-income people who experience disproportionate rates of obesity. But, “these findings are similar to ones observed from non–safety-net settings, which can indicate some potential transferability.”

Asked to comment, session moderator John D. Clark, MD, PhD, Chief Population Health Officer at Sharp Rees-Stealy Medical Group, San Diego, California, told this news organization that the findings didn’t surprise him. “I’d say that medical education around obesity has definitely improved, and training is improving but it’s not uniform. The treatment of obesity as a disease, especially with some of the newer medical treatments, is not standard of care and practiced widely.”

The study involved a standard-model Knowledge, Attitudes, and Practices questionnaire, distributed electronically for anonymous responses among both trained and in-training primary care providers. It contained a total of 43 items, 7 of them demographic, 11 on knowledge, 9 regarding attitudes, and 16 asking about practices.

The hospital is the largest safety-net hospital in New England, with a patient population that includes 58% enrolled in Medicaid, 32% Black/African American individuals, 24% identifying as Hispanic/Latino individuals, and 37% living below the poverty line.

The 96 responding providers (from a total 350 invited) all worked in either family medicine or internal medicine. The trained providers included both attending MDs and nurse practitioners, while those in-training were residents in one of those two specialties. Two thirds were women. The majority were aged 20-30 years (49.45%) or 31-40 years (27.47%).

Overall, 73.63% reported having received some type of obesity training. Just over half (52.08%) reported receiving that training during medical or nursing school, while 43.75% reported receiving it during residency.

When asked to choose from a list of conditions to pick which are considered weight-related comorbidities, between 80% and 90% choose type 2 diabetes, obstructive sleep apnea (OSA), hypertension, hyperlipidemia, nonalcoholic fatty liver disease, and coronary artery disease. Fewer, but still a majority, also listed osteoarthritis and gastroesophageal reflux disease. However, respondents were less likely to cite cancer, mood disorders, or chronic kidney disease as being related to obesity.

Asked to list benefits of a 10% body weight loss, most recognized reductions in OSA, glycemia, cardiovascular disease risk, osteoarthritis, and hepatic steatosis. But, only about half knew weight loss could also improve urinary incontinence.

Only 25% could correctly name both indications for AOMs. Just 27.1% knew that one was a body mass index (BMI) ≥ 27 with comorbidities, while 46.9% knew BMI ≥ 30 without comorbidities was an AOM indication. Only 9.4% were correct on both of those indications for bariatric surgery.

“Reassuringly,” Campos said, the majority either “disagreed” or “strongly disagreed” that “lack of will power” contributes to obesity. However, more than 20% agreed that “lack of exercise or physical activity” contributed.

Overall, 73% of the trained providers and 59% of those in training reported that they prescribe AOMs. Asked about their comfort level in prescribing specific types of AOMs, many more endorsed semaglutide and liraglutide than older medications such as bupropion/naltrexone and phentermine/topiramate.

Asked about factors that influence their comfort with prescribing AOMs, the top five factors selected, in order, were side-effect knowledge, insurance coverage, safety issues, and dosing knowledge. Fewer respondents endorsed “patient’s ideas, concerns, and expectations,” cost, or efficacy.

Referrals to nutrition services were endorsed more often than to obesity medicine specialists or bariatric surgery.

Asked about barriers to obesity treatment in their practices, “time constraints” was the most frequently endorsed, followed by “lack of training or knowledge,” “patient adherence and motivation,” and “limited resources.”

“What are the future directives? We feel we have the need to provide ongoing obesity management, education and assistance to primary care providers, including support for securing coverage for treatments,” Campos said.

He added that Boston Medical Center is now developing and implementing an embedded weight management program within primary care “to assist the front line of obesity care.”

Asked by this news organization whether he believes the rise of GLP-1 drugs will make a difference, Campos said “Definitely, I think with that momentum obesity medicine as a whole will gain more attention and hopefully more implementation in the curricula for medical and nursing schools, because in the end it requires a multidisciplinary approach.”

Campos and Clark had no disclosures.

AI-Assisted Colonoscopy Linked to Higher Rate of Benign Lesion Removal

Article Type
Changed
Thu, 11/07/2024 - 09:42

Artificial intelligence–assisted colonoscopy (AIAC) with computer-aided detection (CADe) technology may improve adenoma detection rate (ADR), but it’s also associated with higher detection and removal of non-neoplastic lesions, according to a study presented at the annual meeting of the American College of Gastroenterology (ACG).

In particular, AIAC led to a statistically and clinically significant increase in the proportion of exams that detected lesions that after resection were all found to be benign, compared with unassisted colonoscopy.

University of Minnesota
Dr. Tessa Herman

“The potential implications include increased procedural risks, as well as costs, such as pathology costs and other healthcare expenditures, without any additional colorectal cancer prevention benefit,” said lead author Tessa Herman, MD, chief resident of internal medicine at the University of Minnesota, Minneapolis, and Minneapolis Veterans Affairs Health Care System.

In a previous implementation trial at the Minneapolis VA Medical Center, Herman and colleagues compared ADR between a group of patients undergoing AIAC and a historical cohort of patients who had non–AI-assisted colonoscopy.

In this subsequent study, the research team conducted an ad hoc analysis of data from the previous trial to determine the proportion of colonoscopies for screening, surveillance, and positive fecal immunochemical tests which detect lesions that after resection are all found to be benign. They excluded colonoscopies conducted for diagnostic indications or inflammatory bowel disease, as well as incomplete colonoscopies, and for those with inadequate bowel preparation.

Overall, they studied 441 non-AIAC colonoscopies (between November 2022 and April 2023) and 599 AIAC colonoscopies (between May 2023 and October 2023). The groups were balanced, and there were no significant differences in patient demographics, endoscopists, AI technology, procedure time, or average number of polyps detected.

In the non-AIAC cohort, 37 cases (8.4%) had polypectomies that revealed only benign lesions, as compared with 74 cases (12.4%) in the AIAC cohort. The most common resected lesions were benign colonic mucosa, lymphoid aggregates, and hyperplastic polyps.

Applied to the 15 million colonoscopies conducted in the United States per year, the findings indicate that full adoption of AIAC could result in about 600,000 more colonoscopies in which only benign, nonadenomatous lesions are removed, compared with traditional colonoscopy, Herman said.

More study of AIAC is needed, said Daniel Pambianco, MD, managing partner of GastroHealth-Charlottesville in Virginia and the 2023 ACG president. “This technology is in a fledging stage, and the more data we have, the more helpful it’ll be to know if we’re removing the right lesions at a better rate.”

“There’s a hope that assistance will improve detection, removal of polyps, and ultimately, colon cancer,” added Pambianco, who comoderated the session on colorectal cancer prevention.

Future longitudinal studies should monitor both ADR and benign lesion resection rates with AIAC, and modeling studies could determine the benefits and costs of the technology, Herman said. In addition, development of hybrid CADe and computer-aided diagnosis systems could mitigate concerns about excessive benign lesion resection with AI tools.

Dr. Sita Chokhavatia

Clinicians already are able to find colon mucosa that are polypoid or lymphoid aggregates during colonoscopy without AI assistance, said the session’s comoderator, Sita Chokhavatia, MD, AGAF, a gastroenterologist with Valley Medical Group in Ridgewood, New Jersey. 

“Instead, we need a tool that can help us to not remove these polyps that are not neoplastic,” she said. “With future developments, we may be able to take it to the next step where the algorithm tells us that it’s benign and not to touch it.”

The study was named an ACG Newsworthy Abstract. Herman, Pambianco, and Chokhavatia reported no relevant disclosures.

Short-Course Vasoconstrictors After EVL: Time for a New Standard of Care?

Article Type
Changed
Thu, 11/07/2024 - 09:36

New research challenges the traditional practice of continuing vasoconstrictor therapy for 5 days after endoscopic variceal ligation (EVL) for acute variceal bleeding, finding that a shorter course of 1-3 days may suffice, without raising the risk for rebleeding, if the initial ligation successfully controls bleeding.

“This approach would allow earlier discharge from the hospital and reduce the risk of adverse events, all without sacrificing treatment efficacy or compromising patient safety,” Sushrut Ingawale, MD, MBBS, Quinnipiac University School of Medicine, North Haven, and St. Vincent’s Medical Center, Bridgeport, both in Connecticut, said in a presentation at the annual meeting of the American College of Gastroenterology (ACG).

Ingawale called for a “re-evaluation of existing protocols, emphasizing the potential to update current protocols to reflect shorter, more personalized” duration of vasoconstrictor therapy in these patients.

Rush University Medical Center
Dr. Nancy Reau

Commenting on this research, Nancy Reau, MD, AGAF, of Rush University in Chicago, Illinois, said: “We should always question the standard of care.”

“Vasoconstrictors for 5 days is the standard of care, but this could lead to prolonged hospitalization in patients who are otherwise doing well after endoscopic intervention. Recognizing that a shorter course of vasoconstrictor treatment may have equal outcome is very important though it may not be appropriate for all patients, especially those at high risk for rebleeding,” said Reau.
 

Outdated Guidelines?

In his presentation, Ingawale noted that current guidelines that recommend continuing vasoconstrictors, like octreotide or terlipressin, for at least 3-5 days after EVL for acute variceal bleeding are based primarily on old studies in which sclerotherapy was the primary hemostatic method.

The study team assessed comparative outcomes based on the duration of vasoconstrictors after EVL for acute variceal bleeding in a systematic review and network meta-analysis of 11 randomized controlled trials.

The studies had a total of 816 patients who were grouped based on the duration vasoconstrictor therapy: 24 hours or less (group 1), 24-72 hours (group 2), and 72-120 hours (group 3).

There was no significant difference in the risk for rebleeding in group 1 (risk ratio [RR], 1.36; 95% CI, 0.48-3.52) and group 2 (RR, 1.34; 95% CI, 0.42-4.54) vs group 3.

“This finding was even consistent when we compared individual durations” of 0, 12, 24, 48, and 72 hours vs 120 hours, Ingawale said.

There was also no statistically significant difference in the 5-day mortality risk between group 1 (RR, 0.66; 95% CI, 0.09-2.52) and group 2 (RR, 1.08; 95% CI, 0.15-6.43) or the 30-day mortality risk between group 1 (RR, 1.18; 95% CI, 0.51-2.51) and group 2 (RR, 0.98; 95% CI, 0.36-2.52) vs group 3.
 

Rapidly Evolving Area

“Our network meta-analysis did not show any benefit of continuing vasoconstrictors after EVL,” the researchers wrote in their conference abstract. Despite historical precedent, shorter durations may be adequate, “potentially enabling earlier hospital discharge without compromising patient outcomes.”

Ingawale suggested future research should look to identify the subset of patients at a risk for failure to control bleeding who might benefit from the continuation of vasoconstrictors.

“Management of complications of portal hypertension are rapidly evolving and this study will add to the data that drives our guidelines. Seeing this data in a peer reviewed publication will add the necessary validity to impact a change in the treatment paradigm,” Reau said.

The study had no specific funding. Ingawale had no relevant financial relationships. Reau disclosed various relationships with AbbVie, Gilead, Arbutus, Intercept, and Salix.

New research challenges the traditional practice of continuing vasoconstrictor therapy for 5 days after endoscopic variceal ligation (EVL) for acute variceal bleeding, finding that a shorter course of 1-3 days may suffice, without raising the risk for rebleeding, if the initial ligation successfully controls bleeding.

“This approach would allow earlier discharge from the hospital and reduce the risk of adverse events, all without sacrificing treatment efficacy or compromising patient safety,” Sushrut Ingawale, MD, MBBS, Quinnipiac University School of Medicine, North Haven, and St. Vincent’s Medical Center, Bridgeport, both in Connecticut, said in a presentation at the annual meeting of the American College of Gastroenterology (ACG).

Ingawale called for a “re-evaluation of existing protocols, emphasizing the potential to update current protocols to reflect shorter, more personalized” duration of vasoconstrictor therapy in these patients.

Commenting on this research, Nancy Reau, MD, AGAF, of Rush University in Chicago, Illinois, said: “We should always question the standard of care.”

“Vasoconstrictors for 5 days is the standard of care, but this could lead to prolonged hospitalization in patients who are otherwise doing well after endoscopic intervention. Recognizing that a shorter course of vasoconstrictor treatment may have equal outcome is very important though it may not be appropriate for all patients, especially those at high risk for rebleeding,” said Reau.
 

Outdated Guidelines?

Nutrition and Medical Education

Article Type
Changed
Wed, 11/06/2024 - 15:42

How comfortable are you giving nutritional advice to your patients? When you offer it are you basing your advice on something you learned during medical school or your training? Was it included in a course devoted to nutrition? Did you learn it later as part of continuing medical education course (CME)? Or was it just something you just picked up from your experience seeing patients (osmosis)? It is very unlikely that a significant portion, or any part for that matter, of your medical training was devoted to nutrition. It certainly wasn’t during my training.

I recently read an interview with Emily M. Broad Leib, JD, faculty director of the Harvard School Center for Health Law and Policy Innovation, Cambridge, Massachusetts, who would like to correct that deficiency. She feels doctors need to know more about food and that acquiring that knowledge should be a significant component of their formal training.

Dr. William G. Wilkoff practiced primary care pediatrics in Brunswick, Maine, for nearly 40 years.
Dr. William G. Wilkoff

In the interview, Leib said that “roughly 86% of physicians report they do not feel adequately trained to answer basic questions on diet or nutrition.” She also notes that while “72% of entering medical students report they believe food is important to health” less than 50% retained this belief after graduation.

Leib and associates feel they have recently reached a milestone in their efforts to include nutrition in the mainstream of medical education this fall by publishing a paper that demonstrates “consensus on doctor-approved nutritional standard for medical schools and residency programs.”
 

36 Recommended Competencies

Curious about what these nutrition experts chose to include in medical training, I decided to drill down into the list of 36 consensus-driven competencies they had agreed upon.

It was an interesting voyage into a forest of redundancies, many of which can be boiled down to having the student demonstrate that he/she understands that what we eat is important to our health and that there is a complex web of relationships connecting our society to the food consume.

Some of the recommended competencies I found make perfect sense. For example the student/trainee should be able to take a diet and food history and be able to interpret lab values and anthropometric measurements and be able to discuss the patient’s weight and diet with sensitivity while keeping in mind his/her own biases about food.

Some other recommendations are more problematic, for example, “performs a comprehensive nutrition-focused physical examination” or “demonstrates knowledge of how to create culinary nutrition SMART [Specific, Measurable, Achievable, Relevant, and Time-Bound] goals for personal use and for patient care” or “provides brief counseling interventions to help patients decrease visceral adiposity or reduce the risk of metabolic syndrome.” Including competencies like these demonstrates a lack of understanding of the time restraints and realities of a primary care physician’s life and training.

Instead of simply reinforcing the prospective physician’s preexisting assumption that food and health are entwined and discussing when and how to consult a nutrition expert, these 36 competencies seem to be an attempt to create fast-tracked part-time dietitians and nutrition advocates out of medical students and trainees who already believe that nutrition is important for health but also have a very full plate of clinical responsibilities ahead of them.

The study that Leib quotes — that 72% of medical students believed food was important in health while after graduation only 50% of agreed — doesn’t necessarily mean that professors are preaching that food was unimportant. It is more likely by the end of medical school the students have seen that food must share the spotlight with numerous other factors that influence their patients’ health.
 

 

 

‘A More Appropriate Focus’

In my experience, diet and lifestyle counseling done well is extremely time consuming and best done by people for whom that is their specialty. A more appropriate focus for a list of nutritional competencies for physicians in training would be for the student to achieve an understanding of when and how to consult a dietitian and then how to support and evaluate the dietitian’s recommendations to the patient.

Finally, I don’t think we can ignore a serious public relations problem that hangs like a cloud over the nutrition advocacy community. It is the same one that casts a shadow on the medical community as well. It is a common perception among the lay public that nutritionists (and physicians) are always changing their recommendations when it comes to food. What is believable? Just think about eggs, red wine, or introducing peanuts to infants, to name just a few. And what about the food pyramids that seem to have been rebuilt every several years? The problem is compounded when some “credentialed” nutritionists and physicians continue to make dietary pronouncements with only a shred of evidence or poorly documented anecdotal observations.

The first of the 36 competencies I reviewed reads: “Provide evidence-based, culturally sensitive nutrition and food recommendations for the prevention and treatment of disease.” When it comes to nutrition the “evidence” can be tough to come by. The natural experiments in which individuals and populations had extremely limited access to a certain nutrients (eg, scurvy) don’t occur very often. Animal studies don’t always extrapolate to humans. And, observational studies concerning diet often have co-factors that are difficult to control and must run over time courses that can tax even the most patient researchers.

I certainly applaud Leib and associates for promoting their primary goal of including more about of the relationship between food and health in the medical school and trainee curriculum. But I must voice a caution to be careful to keep it truly evidence-based and in a format that acknowledges the realities of the life and education of a primary care provider.

The best nutritional advice I ever received in my training was from an older pediatric professor who suggested that a healthy diet consisted of everything in moderation.

Dr. Wilkoff practiced primary care pediatrics in Brunswick, Maine, for nearly 40 years. He has authored several books on behavioral pediatrics, including “How to Say No to Your Toddler.” Other than a Littman stethoscope he accepted as a first-year medical student in 1966, Dr. Wilkoff reports having nothing to disclose.

Sea Buckthorn

Article Type
Changed
Wed, 11/06/2024 - 15:07

A member of the Elaeagnaceae family, Hippophae rhamnoides, better known as sea buckthorn, is a high-altitude wild shrub endemic to Europe and Asia with edible fruits and a lengthy record of use in traditional Chinese medicine.1-6 Used as a health supplement and consumed in the diet throughout the world,5 sea buckthorn berries, seeds, and leaves have been used in traditional medicine to treat burns/injuries, edema, hypertension, inflammation, skin grafts, ulcers, and wounds.4,7

This hardy plant is associated with a wide range of biologic activities, including anti-atherogenic, anti-atopic dermatitis, antibacterial, anticancer, antifungal, anti-inflammatory, antimicrobial, antioxidant, anti-psoriasis, anti-sebum, anti-stress, anti-tumor, cytoprotective, hepatoprotective, immunomodulatory, neuroprotective, radioprotective, and tissue regenerative functions.4,5,8-11Sea buckthorn has also been included in several cosmeceutical formulations to treat wrinkles, scars, pigmentary conditions, and hair disorders, as well as to rejuvenate, even, and smooth the skin.4

Key Constituents

Functional constituents identified in sea buckthorn include alkaloids, carotenoids, flavonoids, lignans, organic acids, phenolic acids, proanthocyanidins, polyunsaturated acids (including omega-3, -6, -7, and -9), steroids, tannins, terpenoids, and volatile oils, as well as nutritional compounds such as minerals, proteins, and vitamins.4,5,11 Sea buckthorn pericarp oil contains copious amounts of saturated palmitic acid (29%-36%) and omega-7 unsaturated palmitoleic acid (36%-48%), which fosters cutaneous and mucosal epithelialization, as well as linoleic (10%-12%) and oleic (4%-6%) acids.12,6 Significant amounts of carotenoids as well as alpha‐linolenic fatty acid (38%), linoleic (36%), oleic (13%), and palmitic (7%) acids are present in sea buckthorn seed oil.6

Polysaccharides

In an expansive review on the pharmacological activities of sea buckthorn polysaccharides, Teng and colleagues reported in April 2024 that 20 diverse polysaccharides have been culled from sea buckthorn and exhibited various healthy activities, including antioxidant, anti-fatigue, anti-inflammatory, anti-obesity, anti-tumor, hepatoprotective, hypoglycemic, and immunoregulation, and regulation of intestinal flora activities.1

Proanthocyanidins and Anti-Aging

In 2023, Liu and colleagues investigated the anti–skin aging impact of sea buckthorn proanthocyanidins in D-galactose-induced aging in mice given the known free radical scavenging activity of these compounds. They found the proanthocyanidins mitigated D-galactose-induced aging and can augment the total antioxidant capacity of the body. Sea buckthorn proanthocyanidins can further attenuate the effects of skin aging by regulating the TGF-beta1/Smads pathway and MMPs/TIMP system, thus amplifying collagen I and tropoelastin content.13

Dr. Leslie S. Baumann

A year earlier, many of the same investigators assessed the possible protective activity of sea buckthorn proanthocyanidins against cutaneous aging engendered by oxidative stress from hydrogen peroxide. The compounds amplified superoxide dismutase and glutathione antioxidant functions. The extracts also fostered collagen I production in aging human skin fibroblasts via the TGF-beta1/Smads pathway and hindered collagen I degradation by regulating the MMPs/TIMPs system, which maintained extracellular matrix integrity. Senescent cell migration was also promoted with 100 mcg/mL of sea buckthorn proanthocyanidins. The researchers concluded that this sets the stage for investigating how sea buckthorn proanthocyanidins can be incorporated in cosmetic formulations.14 In a separate study, Liu and colleagues demonstrated that sea buckthorn proanthocyanidins can attenuate oxidative damage and protect mitochondrial function.9

 

 

Acne and Barrier Functions

The extracts of H rhamnoides and Cassia fistula in a combined formulation were found to be effective in lowering skin sebum content in humans with grade I and grade II acne vulgaris in a 2014 single-blind, randomized, placebo-controlled, split-face study with two groups of 25 patients each (aged 18-37 years).15 Khan and colleagues have also reported that a sea buckthorn oil-in-water emulsion improved barrier function in human skin as tested by a tewameter and corneometer (noninvasive probes) in 13 healthy males with a mean age of 27 ± 4.8 years.16

Anti-Aging, Antioxidant, Antibacterial, Skin-Whitening Activity

Zaman and colleagues reported in 2011 that results from an in vivo study of the effects of a sea buckthorn fruit extract topical cream on stratum corneum water content and transepidermal water loss indicated that the formulation enhanced cell surface integrin expression thus facilitating collagen contraction.17

In 2012, Khan and colleagues reported amelioration in skin elasticity, thus achieving an anti-aging result, from the use of a water-in-oil–based hydroalcoholic cream loaded with fruit extract of H rhamnoides, as measured with a Cutometer.18 The previous year, some of the same researchers reported that the antioxidants and flavonoids found in a topical sea buckthorn formulation could decrease cutaneous melanin and erythema levels.

More recently, Gęgotek and colleagues found that sea buckthorn seed oil prevented redox balance and lipid metabolism disturbances in skin fibroblasts and keratinocytes caused by UVA or UVB. They suggested that such findings point to the potential of this natural agent to confer anti-inflammatory properties and photoprotection to the skin.19

In 2020, Ivanišová and colleagues investigated the antioxidant and antimicrobial activities of H rhamnoides 100% oil, 100% juice, dry berries, and tea (dry berries, leaves, and twigs). They found that all of the studied sea buckthorn products displayed high antioxidant activity (identified through DPPH radical scavenging and molybdenum reducing antioxidant power tests). Sea buckthorn juice contained the highest total content of polyphenols, flavonoids, and carotenoids. All of the tested products also exhibited substantial antibacterial activity against the tested microbes.20

Burns and Wound Healing

In a preclinical study of the effects of sea buckthorn leaf extracts on wound healing in albino rats using an excision-punch wound model in 2005, Gupta and colleagues found that twice daily topical application of the aqueous leaf extract fostered wound healing. This was indicated by higher hydroxyproline and protein levels, a diminished wound area, and lower lipid peroxide levels. The investigators suggested that sea buckthorn may facilitate wound healing at least in part because of elevated antioxidant activity in the granulation tissue.3

A year later, Wang and colleagues reported on observations of using H rhamnoides oil, a traditional Chinese herbal medicine derived from sea buckthorn fruit, as a burn treatment. In the study, 151 burn patients received an H rhamnoides oil dressing (changed every other day until wound healing) that was covered with a disinfecting dressing. The dressing reduced swelling and effusion, and alleviated pain, with patients receiving the sea buckthorn dressing experiencing greater apparent exudation reduction, pain reduction, and more rapid epithelial cell growth and wound healing than controls (treated only with Vaseline gauze). The difference between the two groups was statistically significant.21

 

 

Conclusion

Sea buckthorn has been used for hundreds if not thousands of years in traditional medical applications, including for dermatologic purposes. Emerging data appear to support the use of this dynamic plant for consideration in dermatologic applications. As is often the case, much more work is necessary in the form of randomized controlled trials to determine the effectiveness of sea buckthorn formulations as well as the most appropriate avenues of research or uses for dermatologic application of this traditionally used botanical agent.

A member of the Elaeagnaceae family, Hippophae rhamnoides, better known as sea buckthorn, is a high-altitude wild shrub endemic to Europe and Asia with edible fruits and a lengthy record of use in traditional Chinese medicine.1-6 Used as a health supplement and consumed in the diet throughout the world,5 sea buckthorn berries, seeds, and leaves have been used in traditional medicine to treat burns/injuries, edema, hypertension, inflammation, skin grafts, ulcers, and wounds.4,7

This hardy plant is associated with a wide range of biologic activities, including anti-atherogenic, anti-atopic dermatitis, antibacterial, anticancer, antifungal, anti-inflammatory, antimicrobial, antioxidant, anti-psoriasis, anti-sebum, anti-stress, anti-tumor, cytoprotective, hepatoprotective, immunomodulatory, neuroprotective, radioprotective, and tissue regenerative functions.4,5,8-11Sea buckthorn has also been included in several cosmeceutical formulations to treat wrinkles, scars, pigmentary conditions, and hair disorders, as well as to rejuvenate, even, and smooth the skin.4

Key Constituents

Functional constituents identified in sea buckthorn include alkaloids, carotenoids, flavonoids, lignans, organic acids, phenolic acids, proanthocyanidins, polyunsaturated acids (including omega-3, -6, -7, and -9), steroids, tannins, terpenoids, and volatile oils, as well as nutritional compounds such as minerals, proteins, and vitamins.4,5,11 Sea buckthorn pericarp oil contains copious amounts of saturated palmitic acid (29%-36%) and omega-7 unsaturated palmitoleic acid (36%-48%), which fosters cutaneous and mucosal epithelialization, as well as linoleic (10%-12%) and oleic (4%-6%) acids.12,6 Significant amounts of carotenoids as well as alpha‐linolenic fatty acid (38%), linoleic (36%), oleic (13%), and palmitic (7%) acids are present in sea buckthorn seed oil.6

Polysaccharides

In an expansive review on the pharmacological activities of sea buckthorn polysaccharides, Teng and colleagues reported in April 2024 that 20 diverse polysaccharides have been culled from sea buckthorn and exhibited various healthy activities, including antioxidant, anti-fatigue, anti-inflammatory, anti-obesity, anti-tumor, hepatoprotective, hypoglycemic, and immunoregulation, and regulation of intestinal flora activities.1

Proanthocyanidins and Anti-Aging

In 2023, Liu and colleagues investigated the anti–skin aging impact of sea buckthorn proanthocyanidins in D-galactose-induced aging in mice given the known free radical scavenging activity of these compounds. They found the proanthocyanidins mitigated D-galactose-induced aging and can augment the total antioxidant capacity of the body. Sea buckthorn proanthocyanidins can further attenuate the effects of skin aging by regulating the TGF-beta1/Smads pathway and MMPs/TIMP system, thus amplifying collagen I and tropoelastin content.13

A year earlier, many of the same investigators assessed the possible protective activity of sea buckthorn proanthocyanidins against cutaneous aging engendered by oxidative stress from hydrogen peroxide. The compounds amplified superoxide dismutase and glutathione antioxidant functions. The extracts also fostered collagen I production in aging human skin fibroblasts via the TGF-beta1/Smads pathway and hindered collagen I degradation by regulating the MMPs/TIMPs system, which maintained extracellular matrix integrity. Senescent cell migration was also promoted with 100 mcg/mL of sea buckthorn proanthocyanidins. The researchers concluded that this sets the stage for investigating how sea buckthorn proanthocyanidins can be incorporated in cosmetic formulations.14 In a separate study, Liu and colleagues demonstrated that sea buckthorn proanthocyanidins can attenuate oxidative damage and protect mitochondrial function.9

 

 

Acne and Barrier Functions

The extracts of H rhamnoides and Cassia fistula in a combined formulation were found to be effective in lowering skin sebum content in humans with grade I and grade II acne vulgaris in a 2014 single-blind, randomized, placebo-controlled, split-face study with two groups of 25 patients each (aged 18-37 years).15 Khan and colleagues have also reported that a sea buckthorn oil-in-water emulsion improved barrier function in human skin as tested by a tewameter and corneometer (noninvasive probes) in 13 healthy males with a mean age of 27 ± 4.8 years.16

Anti-Aging, Antioxidant, Antibacterial, Skin-Whitening Activity

Zaman and colleagues reported in 2011 that results from an in vivo study of the effects of a sea buckthorn fruit extract topical cream on stratum corneum water content and transepidermal water loss indicated that the formulation enhanced cell surface integrin expression thus facilitating collagen contraction.17

In 2012, Khan and colleagues reported amelioration in skin elasticity, thus achieving an anti-aging result, from the use of a water-in-oil–based hydroalcoholic cream loaded with fruit extract of H rhamnoides, as measured with a Cutometer.18 The previous year, some of the same researchers reported that the antioxidants and flavonoids found in a topical sea buckthorn formulation could decrease cutaneous melanin and erythema levels.

They suggested that such findings point to the potential of this natural agent to confer anti-inflammatory properties and photoprotection to the skin.19

In 2020, Ivanišová and colleagues investigated the antioxidant and antimicrobial activities of H rhamnoides 100% oil, 100% juice, dry berries, and tea (dry berries, leaves, and twigs). They found that all of the studied sea buckthorn products displayed high antioxidant activity (identified through DPPH radical scavenging and molybdenum reducing antioxidant power tests). Sea buckthorn juice contained the highest total content of polyphenols, flavonoids, and carotenoids. All of the tested products also exhibited substantial antibacterial activity against the tested microbes.20

Burns and Wound Healing

In a preclinical study of the effects of sea buckthorn leaf extracts on wound healing in albino rats using an excision-punch wound model in 2005, Gupta and colleagues found that twice daily topical application of the aqueous leaf extract fostered wound healing. This was indicated by higher hydroxyproline and protein levels, a diminished wound area, and lower lipid peroxide levels.

In the study, 151 burn patients received an H rhamnoides oil dressing (changed every other day until wound healing) that was covered with a disinfecting dressing. The dressing reduced swelling and effusion, and alleviated pain, with patients receiving the sea buckthorn dressing experiencing greater apparent exudation reduction, pain reduction, and more rapid epithelial cell growth and wound healing than controls (treated only with Vaseline gauze). The difference between the two groups was statistically significant.21

Experts Challenge New Diagnostic Criteria for Alzheimer’s disease

Article Type
Changed
Wed, 11/06/2024 - 15:03

A group of international experts is challenging revised diagnostic criteria for Alzheimer’s disease as laid out by the Alzheimer’s Association earlier in 2024.

In a paper published online in JAMA Neurology, the International Working Group (IWG), which includes 46 experts from 17 countries, is recommending that the diagnosis of Alzheimer’s disease be limited to individuals with mild cognitive impairment or dementia and not be applied to cognitively normal individuals with Alzheimer’s disease biomarkers such as amyloid-beta 42/40 or p-tau.

Clinicians should be “very careful” about using the “A” word (Alzheimer’s) for cognitively unimpaired people with Alzheimer’s disease biomarkers, said the paper’s first author Bruno Dubois, MD, professor of neurology, Sorbonne University and Department of Neurology, Pitié-Salpêtrière Hospital, Paris, France.

Providing an Alzheimer’s disease diagnosis to those who have a high chance of never developing cognitive impairment can be psychologically harmful, said Dubois.

“It’s not something small like telling someone they have a fever. Just imagine you’re 65 years old and are amyloid positive, and you’re told you have Alzheimer’s disease. It affects the decisions you make for the rest of your life and changes your vision of your future, even though you may never develop the disease,” he added.
 

Divergent View

The IWG’s perspective on Alzheimer’s disease contrasts with a recent proposal from the Alzheimer’s Association. The Alzheimer’s Association criteria suggest that Alzheimer’s disease should be regarded solely as a biological entity, which could include cognitively normal individuals with one core Alzheimer’s disease biomarker.

The IWG noted that its concerns regarding the application of a purely biological definition of Alzheimer’s disease in clinical practice prompted the group to consider updating its guidelines, potentially offering “an alternative definitional view of Alzheimer’s disease as a clinical-biological construct for clinical use.”

The group conducted a PubMed search for relevant Alzheimer’s disease articles, and included references, published between July 2020 and March 2024. The research showed the majority of biomarker-positive, cognitively normal individuals will not become symptomatic during their lifetime.

The risk of a 55-year-old who is amyloid positive developing Alzheimer’s disease is not that much higher than that for an individual of a similar age who is amyloid negative, Dubois noted. “There’s an 83% chance that person will never develop Alzheimer’s disease.”

Disclosing a diagnosis of Alzheimer’s disease to cognitively normal people with only one core Alzheimer’s disease biomarker represents “the most problematic implication of a purely biological definition of the disease,” the authors noted.

“A biomarker is a marker of pathology, not a biomarker of disease,” said Dubois, adding that a person may have markers for several different brain diseases.

The IWG recommends the following nomenclature: At risk for Alzheimer’s disease for those with Alzheimer’s disease biomarkers but low lifetime risk and presymptomatic Alzheimer’s disease for those with Alzheimer’s disease biomarkers with a very high lifetime risk for progression such as individuals with autosomal dominant genetic mutations and other distinct biomarker profiles that put them at extremely high lifetime risk of developing the disease.

Dubois emphasized the difference between those showing typical Alzheimer’s disease symptoms with positive biomarkers who should be considered to have the disease and those with positive biomarkers but no typical Alzheimer’s disease symptoms who should be considered at risk.

This is an important distinction as it affects research approaches and assessment of risks, he said.

For low-risk asymptomatic individuals, the IWG does not recommend routine diagnostic testing outside of the research setting. “There’s no reason to send a 65-year-old cognitively normal subject off to collect biomarker information,” said Dubois.

He reiterated the importance of clinicians using appropriate and sensitive language surrounding Alzheimer’s disease when face to face with patients. This issue “is not purely semantic; this is real life.”

For these patients in the clinical setting, “we have to be very careful about proposing treatments that may have side effects,” he said.

However, this does not mean asymptomatic at-risk people should not be studied to determine what pharmacological interventions might prevent or delay the onset of clinical disease, he noted.

Presymptomatic individuals who are at a high risk of developing Alzheimer’s disease “should be the target for clinical trials in the future” to determine best ways to delay the conversion to Alzheimer’s disease, he said.

The main focus of such research should be to better understand the “biomarker pattern profile” that is associated with a high risk of developing Alzheimer’s disease, said Dubois.
 

 

 

Plea for Unity

In an accompanying editorial, Ronald C. Petersen, PhD, MD, director, Mayo Clinic Alzheimer’s Disease Research Center and Mayo Clinic Study of Aging, Rochester, Minnesota, and colleagues outline the difference between the IWG and Alzheimer’s Association positions.

As the IWG uses Alzheimer’s disease to define those with cognitive impairment and the Alzheimer’s Association group uses Alzheimer’s disease to define those with the pathology of the disease, the field is now at a crossroads. “Do we name the disease before clinical symptoms?” they asked.

They note that Alzheimer’s Association criteria distinguish between a disease and an illness, whereas the IWG does not. “As such, although the primary disagreement between the groups is semantic, the ramifications of the labeling can be significant.”

It is “incumbent” that the field “come together” on an Alzheimer’s disease definition, the editorial concluded. “Neither the Alzheimer’s Association or IWG documents are appropriate to serve as a guide for how to apply biomarkers in a clinical setting. Appropriate-use criteria are needed to form a bridge between biological frameworks and real-world clinical practice so we can all maximally help all of our patients with this disorder.”

In a comment, Reisa Sperling, MD, professor of neurology, Harvard Medical School, and director, Center for Alzheimer Research and Treatment, Brigham and Women’s Hospital and Massachusetts General Hospital, all in Boston, who is part of the Alzheimer’s Association work group that published the revised criteria for diagnosis and staging of Alzheimer’s disease, likened Alzheimer’s disease, which begins in the brain many years before dementia onset, to cardiovascular disease in that it involves multiple processes. She noted the World Health Organization classifies cardiovascular disease as a “disease” prior to clinical manifestations such as stroke and myocardial infarction.

“If someone has Alzheimer’s disease pathology in their brain, they are at risk for dementia or clinical manifestations of the disease — just like vascular disease quantifies the risk of stroke or heart attack, not risk of developing ‘vascular disease’ if the underlying vascular disease is already present,” said Sperling.

A large part of the controversy is related to terminology and the “stigma” of the “A” word in the same way there used to be fear around using the “C” word — cancer, said Sperling.

“Once people began talking about cancer publicly as a potentially treatable disease and began getting screened and diagnosed before symptoms of cancer were manifest, this has had a tremendous impact on public health.”

She clarified that her work group does not recommend screening asymptomatic people with Alzheimer’s disease biomarkers. “We actually need to prove that treating at the preclinical stage of the disease is able to prevent clinical impairment and dementia,” she said, adding “hopefully, we are getting closer to this.”

Dubois reported no relevant disclosures. Petersen reported receiving personal fees from Roche, Genentech, Eli Lilly and Company, Eisai, and Novo Nordisk outside the submitted work and royalties from Oxford University Press, UpToDate, and Medscape educational activities.

How Extreme Rainfall Amplifies Health Risks

Article Type
Changed
Wed, 11/06/2024 - 12:34

Climate change is intensifying the variability of precipitation caused by extreme daily and overall rainfall events. Awareness of the effects of these events is crucial for understanding the complex health consequences of climate change. The connections between health and climate have been recognized by physicians and patients even when climatology did not have the status of an exact science. Physicians have often advised their patients to move to a better climate, and when they did, the recommendation was rarely based on precise scientific knowledge. However, the benefits of changing environments were often so evident that they were indisputable.

Today, advanced models, satellite imagery, and biological approaches such as environmental epigenetics are enhancing our understanding of health risks related to climate change.
 

Extreme Rainfall and Health

The increase in precipitation variability is linked to climate warming, which leads to higher atmospheric humidity and extreme rainfall events. These manifestations can cause rapid weather changes, increasing interactions with harmful aerosols and raising the risk for various cardiovascular and respiratory conditions. However, a full understanding of the association between rain and health has been hindered by conflicting results and methodological issues (limited geographical locations and short observation durations) in studies.

The association between rainfall intensity and health effects is likely nonlinear. Moderate precipitation can mitigate summer heat and help reduce air pollution, an effect that may lower some environmental health risks. Conversely, intense, low-frequency, short-duration rainfall events can have particularly harmful effects on health, as such events can trigger rapid weather changes, increased proliferation of pathogens, and a rise in the risk of various pollutants, potentially exacerbating health conditions.
 

Rain and Mortality

Using an intensity-duration-frequency model of three rainfall indices (high intensity, low frequency, short duration), a study published in October 2024 combined these with mortality data from 34 countries or regions. Researchers estimated associations between mortality (all cause, cardiovascular, and respiratory) and rainfall events with different return periods (the average time expected before an extreme event of a certain magnitude occurs again) and crucial effect modifiers, including climatic, socioeconomic, and urban environmental conditions.

The analysis included 109,954,744 deaths from all causes; 31,164,161 cardiovascular deaths; and 11,817,278 respiratory deaths. During the study period, from 1980 to 2020, a total of 50,913 rainfall events with a 1-year return period, 8362 events with a 2-year return period, and 3301 events with a 5-year return period were identified.

The most significant finding was a global positive association between all-cause mortality and extreme rainfall events with a 5-year return period. One day of extreme rainfall with a 5-year return period was associated with a cumulative relative risk (RRc) of 1.08 (95% CI, 1.05-1.11) for daily mortality from all causes. Rainfall events with a 2-year return period were associated with increased daily respiratory mortality (RRc, 1.14), while no significant effect was observed for cardiovascular mortality during the same period. Rainfall events with a 5-year return period were associated with an increased risk for both cardiovascular mortality (RRc, 1.05) and respiratory mortality (RRc, 1.29), with the respiratory mortality being significantly higher.
 

Points of Concern

According to the authors, moderate to high rainfall can exert protective effects through two main mechanisms: Improving air quality (rainfall can reduce the concentration of particulate matter 2.5 cm in diameter or less in the atmosphere) and behavioral changes in people (more time spent in enclosed environments, reducing direct exposure to outdoor air pollution and nonoptimal temperatures). As rainfall intensity increases, the initial protective effects may be overshadowed by a cascade of negative impacts including:

  • Critical resource disruptions: Intense rainfall can cause severe disruptions to access to healthcare, infrastructure damage including power outages, and compromised water and food quality.
  • Physiological effects: Increased humidity levels facilitate the growth of airborne pathogens, potentially triggering allergic reactions and respiratory issues, particularly in vulnerable individuals. Rapid shifts in atmospheric pressure and temperature fluctuations can lead to cardiovascular and respiratory complications.
  • Indirect effects: Extreme rainfall can have profound effects on mental health, inducing stress and anxiety that may exacerbate pre-existing mental health conditions and indirectly contribute to increased overall mortality from nonexternal causes.

The intensity-response curves for the health effects of heavy rainfall showed a nonlinear trend, transitioning from a protective effect at moderate levels of rainfall to a risk for severe harm when rainfall intensity became extreme. Additionally, the significant effects of extreme events were modified by various types of climate and were more pronounced in areas characterized by low variability in precipitation or sparse vegetation cover.

The study demonstrated that various local factors, such as climatic conditions, climate type, and vegetation cover, can potentially influence cardiovascular and respiratory mortality and all-cause mortality related to precipitation. The findings may help physicians convey to their patients the impact of climate change on their health.

These manifestations can cause rapid weather changes, increasing interactions with harmful aerosols and raising the risk for various cardiovascular and respiratory conditions. However, a full understanding of the association between rain and health has been hindered by conflicting results and methodological issues (limited geographical locations and short observation durations) in studies.

The association between rainfall intensity and health effects is likely nonlinear. Moderate precipitation can mitigate summer heat and help reduce air pollution, an effect that may lower some environmental health risks. Conversely, intense, low-frequency, short-duration rainfall events can have particularly harmful effects on health, as such events can trigger rapid weather changes, increased proliferation of pathogens, and a rise in the risk of various pollutants, potentially exacerbating health conditions.
 

Rain and Mortality

Using an intensity-duration-frequency model of three rainfall indices (high intensity, low frequency, short duration), a study published in October 2024 combined these with mortality data from 34 countries or regions. Researchers estimated associations between mortality (all cause, cardiovascular, and respiratory) and rainfall events with different return periods (the average time expected before an extreme event of a certain magnitude occurs again) and crucial effect modifiers, including climatic, socioeconomic, and urban environmental conditions.

The analysis included 109,954,744 deaths from all causes; 31,164,161 cardiovascular deaths; and 11,817,278 respiratory deaths. During the study period, from 1980 to 2020, a total of 50,913 rainfall events with a 1-year return period, 8362 events with a 2-year return period, and 3301 events with a 5-year return period were identified.

The most significant finding was a global positive association between all-cause mortality and extreme rainfall events with a 5-year return period. One day of extreme rainfall with a 5-year return period was associated with a cumulative relative risk (RRc) of 1.08 (95% CI, 1.05-1.11) for daily mortality from all causes. Rainfall events with a 2-year return period were associated with increased daily respiratory mortality (RRc, 1.14), while no significant effect was observed for cardiovascular mortality during the same period. Rainfall events with a 5-year return period were associated with an increased risk for both cardiovascular mortality (RRc, 1.05) and respiratory mortality (RRc, 1.29), with the respiratory mortality being significantly higher.
 

Points of Concern

According to the authors, moderate to high rainfall can exert protective effects through two main mechanisms: Improving air quality (rainfall can reduce the concentration of particulate matter 2.5 cm in diameter or less in the atmosphere) and behavioral changes in people (more time spent in enclosed environments, reducing direct exposure to outdoor air pollution and nonoptimal temperatures). As rainfall intensity increases, the initial protective effects may be overshadowed by a cascade of negative impacts including:

  • Critical resource disruptions: Intense rainfall can cause severe disruptions to access to healthcare, infrastructure damage including power outages, and compromised water and food quality.
  • Physiological effects: Increased humidity levels facilitate the growth of airborne pathogens, potentially triggering allergic reactions and respiratory issues, particularly in vulnerable individuals. Rapid shifts in atmospheric pressure and temperature fluctuations can lead to cardiovascular and respiratory complications.
  • Indirect effects: Extreme rainfall can have profound effects on mental health, inducing stress and anxiety that may exacerbate pre-existing mental health conditions and indirectly contribute to increased overall mortality from nonexternal causes.

The intensity-response curves for the health effects of heavy rainfall showed a nonlinear trend, transitioning from a protective effect at moderate levels of rainfall to a risk for severe harm when rainfall intensity became extreme. Additionally, the significant effects of extreme events were modified by various types of climate and were more pronounced in areas characterized by low variability in precipitation or sparse vegetation cover.

The study demonstrated that various local factors, such as climatic conditions, climate type, and vegetation cover, can potentially influence cardiovascular and respiratory mortality and all-cause mortality related to precipitation. The findings may help physicians convey to their patients the impact of climate change on their health.
