Women in the United States who followed a Mediterranean-style diet – heavy on fresh foods, fish, and olive oil – around the time of conception had lower risk of developing a pregnancy complication, results of a large new study suggest.

The study included 7,798 women who had not given birth before. The group was geographically, racially, and ethnically diverse.

Researchers led by Nour Makarem, PhD, MS, with the department of epidemiology, Columbia University, New York, published their results in JAMA Network Open.

“Generally, higher intakes of vegetables, fruits, legumes, fish, and whole grains and lower intakes of red and processed meat were associated with lower risk of APOs [adverse pregnancy outcomes],” the authors wrote.
 

21% lower risk of complications

The investigators found that women in the study – who were part of the Nulliparous Pregnancy Outcomes Study: Monitoring Mothers-to-Be, which enrolled 10,038 women between Oct. 1, 2010, and Sept. 30, 2013, and scored high on adherence to a Mediterranean diet – had a 21% lower risk of developing any adverse pregnancy outcome (APO) than those who had low adherence. And the better the adherence, the lower the risk of adverse outcomes, especially preeclampsia or eclampsia and gestational diabetes, the researchers wrote.

The research team also studied how following the diet correlated with gestational high blood pressure, preterm birth, delivery of a small-for-gestational-age infant, and stillbirth.

Women were scored on consumption of nine components: vegetables (excluding potatoes), fruits, nuts, whole grains, legumes, fish, monounsaturated to saturated fat ratio, red and processed meats, and alcohol.
 

No differences by race, ethnicity, or BMI

There were no differences in adverse pregnancy outcomes by race, ethnicity, or the woman’s body mass index before pregnancy, but associations were stronger in the women who were 35 years or older, according to the paper.

The authors pointed out that the women in the study had access to prenatal care at a large academic medical center during their first 3 months of pregnancy so the study may actually underestimate the importance of the diet in the pregnancy outcomes.

Christina Han, MD, division director of maternal-fetal medicine at University of California, Los Angeles, who was not part of the study, said that the results make sense as the researchers looked at the time of conception, which is a time that reflects the way a person chooses to live their life.

“We know that your health state as you enter pregnancy can significantly affect your outcomes for that pregnancy,” she said. “We’ve known for decades now that a Mediterranean diet is good for just about everybody.”
 

Unequal access to foods on diet

Dr. Han said that, while it’s great the researchers were able to confirm the benefit of the Mediterranean diet, it highlights inequity as lower income people are not as likely to be able to afford fresh fruits and vegetables and fish.

“This is a call to arms for our food distribution system to even out the big divide in what patients have access to,” Dr. Han said.

She noted that most of the women in this study were married, non-Hispanic White, and had higher levels of education which may make it hard to generalize these results to the general population.

A limitation of the study is that the women were asked to report what they ate themselves, which can be less accurate than when researchers record what is eaten in a controlled setting.

The researchers suggested a next step: “Long-term intervention studies are needed to assess whether promoting a Mediterranean-style diet around the time of conception and throughout pregnancy can prevent APOs.”

Dr. Makarem reported receiving grants from the National Institutes of Health and the American Heart Association outside the submitted work. One coauthor reported receiving grants from the Eunice Kennedy Shriver National Institute of Child Health and Human Development during the study. One coauthor reported receiving personal fees for serving on the board of directors for iRhythm and from fees paid through Cedars-Sinai Medical Center from Abbott Diagnostics and Sanofi outside the submitted work, and one coauthor reported serving as a clinical end point committee member for GlaxoSmithKline outside the submitted work. No other disclosures were reported. Dr. Han reported no relevant financial relationships.

Irregular and especially long menstrual cycles, particularly in early and mid adulthood, are associated with an increased risk for cardiovascular disease. This finding is demonstrated in a new analysis of the Nurses’ Health Study II.

“To date, several studies have reported increased risks of cardiovascular risk factors or cardiovascular disease in connection with cycle disorders,” Yi-Xin Wang, MD, PhD, a research fellow in nutrition, and associates from the Harvard School of Public Health, Boston, wrote in an article published in JAMA Network Open.

Ute Seeland, MD, speaker of the Gender Medicine in Cardiology Working Group of the German Cardiology Society, said in an interview“We know that women who have indicated in their medical history that they have irregular menstrual cycles, invariably in connection with polycystic ovary syndrome (PCOS), more commonly develop diabetes and other metabolic disorders, as well as cardiovascular diseases.”
 

Cycle disorders’ role

However, the role that irregular or especially long cycles play at different points of a woman’s reproductive life span was unclear. Therefore, the research group investigated the associations in the Nurses’ Health Study II between cycle irregularity and cycle length in women of different age groups who later experienced cardiovascular events.

At the end of this study in 1989, the participants also provided information regarding the length and irregularity of their menstrual cycle from ages 14 to 17 years and again from ages 18 to 22 years. The information was updated in 1993 when the participants were aged 29-46 years. The data from 2019 to 2022 were analyzed.

“This kind of long-term cohort study is extremely rare and therefore something special,” said Dr. Seeland, who conducts research at the Institute for Social Medicine, Epidemiology, and Health Economics at the Charité – University Hospital Berlin.

The investigators used the following cycle classifications: very regular (no more than 3 or 4 days before or after the expected date), regular (within 5-7 days), usually irregular, always irregular, or no periods.

The cycle lengths were divided into the following categories: less than 21 days, 21-25 days, 26-31 days, 32-39 days, 40-50 days, more than 50 days, and too irregular to estimate the length.

The onset of cardiovascular diseases was determined using information from the participants and was confirmed by reviewing the medical files. Relevant to the study were lethal and nonlethal coronary heart diseases (such as myocardial infarction or coronary artery revascularization), as well as strokes.
 

Significant in adulthood

The data from 80,630 study participants were included in the analysis. At study inclusion, the average age of the participants was 37.7 years, and the average body mass index (BMI) was 25.1. “Since it was predominantly White nurses who took part in the study, the data are not transferable to other, more diverse populations,” said Dr. Seeland.

Over 24 years, 1,816 women (2.4%) had a cardiovascular event. “We observed an increased rate of cardiovascular events in women with an irregular cycle and longer cycle, both in early an in mid-adulthood,” wrote Dr. Wang and associates. “Similar trends were also observed for cycle disorders when younger, but this association was weaker than in adulthood.”

Compared with women with very regular cycles, women with irregular cycles or without periods who were aged 14-17 years, 18-22 years, or 29-49 years exhibited a 15%, 36%, and 40% higher risk of a cardiovascular event, respectively.

Similarly, women aged 18-22 years or 29-46 years with long cycles of 40 days or more had a 44% or 30% higher risk of cardiovascular disease, respectively, compared with women with cycle lengths of 26-31 days.

“The coronary heart diseases were decisive for the increase, and less so, the strokes,” wrote the researchers.
 

Classic risk factors?

Dr. Seeland praised the fact that the study authors tried to determine the role that classic cardiovascular risk factors played. “Compared with women with a regular cycle, women with an irregular cycle had a higher BMI, more frequently increased cholesterol levels, and an elevated blood pressure,” she said. Women with a long cycle displayed a similar pattern.

It can be assumed from this that over a woman’s life span, BMI affects the risk of cardiovascular disease. Therefore, Dr. Wang and coauthors adjusted the results on the basis of BMI, which varies over time.

Regarding other classic risk factors that may have played a role, “hypercholesterolemia, chronic high blood pressure, and type 2 diabetes were only responsible in 5.4%-13.5% of the associations,” wrote the researchers.

“Our results suggest that certain characteristics of the menstrual cycle across a woman’s reproductive lifespan may constitute additional risk markers for cardiovascular disease,” according to the authors.

The highest rates of cardiovascular disease were among women with permanently irregular or long cycles in early to mid adulthood, as well as women who had regular cycles when younger but had irregular cycles in mid adulthood. “This indicates that the change from one cycle phenotype to another could be a surrogate marker for metabolic changes, which in turn contribute to the formation of cardiovascular diseases,” wrote the authors.

The study was observational and so conclusions cannot be drawn regarding causal relationships. But Dr. Wang and associates indicate that the most common cause of an irregular menstrual cycle may be PCOS. “Roughly 90% of women with cycle disorders or oligomenorrhea have signs of PCOS. And it was shown that women with PCOS have an increased risk of cardiovascular disease.”

They concluded that “the associations observed between irregular and long cycles in early to mid-adulthood and cardiovascular diseases are likely attributable to underlying PCOS.”

For Dr. Seeland, however, this conclusion is “too monocausal. At no point in time did there seem to be any direct information regarding the frequency of PCOS during the data collection by the respondents.”

For now, we can only speculate about the mechanisms. “The association between a very irregular and long cycle and the increased risk of cardiovascular diseases has now only been described. More research should be done on the causes,” said Dr. Seeland.

In this current age of mass misinformation and disinformation on the Internet, a tongue-in-cheek study that evaluated beliefs and attitudes toward cancer among conspiracy theorists and people who oppose vaccinations has received some harsh criticism.

The study, entitled, “Everything Causes Cancer? Beliefs and Attitudes Towards Cancer Prevention Among Anti-Vaxxers, Flat Earthers, and Reptilian Conspiracists: Online Cross Sectional Survey,” was published in the Christmas 2022 issue of The British Medical Journal (BMJ).

The authors explain that they set out to evaluate “the patterns of beliefs about cancer among people who believed in conspiracies, rejected the COVID-19 vaccine, or preferred alternative medicine.”

They sought such people on social media and online chat platforms and asked them questions about real and mythical causes of cancer.

Almost half of survey participants agreed with the statement, “It seems like everything causes cancer.”

Overall, among all participants, awareness of the actual causes of cancer was greater than awareness of the mythical causes of cancer, the authors report. However, awareness of the actual causes of cancer was lower among the unvaccinated and members of conspiracy groups than among their counterparts.

The authors are concerned that their findings suggest “a direct connection between digital misinformation and consequent potential erroneous health decisions, which may represent a further preventable fraction of cancer.”
 

Backlash and criticism

The study “highlights the difficulty society encounters in distinguishing the actual causes of cancer from mythical causes,” The BMJ commented on Twitter.

However, both the study and the journal received some backlash.

This is a “horrible article seeking to smear people with concerns about COVID vaccines,” commented Clare Craig, a British consultant pathologist who specializes in cancer diagnostics.

The study and its methodology were also harshly criticized on Twitter by Normal Fenton, professor of risk information management at the Queen Mary University of London.

The senior author of the study, Laura Costas, a medical epidemiologist with the Catalan Institute of Oncology, Barcelona, told this news organization that the naysayers on social media, many of whom focused their comments on the COVID-19 vaccine, prove the purpose of the study – that misinformation spreads widely on the internet.

“Most comments focused on spreading COVID-19 myths, which were not the direct subject of the study, and questioned the motivations of BMJ authors and the scientific community, assuming they had a common malevolent hidden agenda,” Ms. Costas said.

“They stated the need of having critical thinking, a trait in common with the scientific method, but dogmatically dismissed any information that comes from official sources,” she added.

Ms. Costas commented that “society encounters difficulty in differentiating actual from mythical causes of cancer owing to mass information. We therefore planned this study with a certain satire, which is in line with the essence of The BMJ Christmas issue.”

The BMJ has a long history of publishing a lighthearted Christmas edition full of original, satirical, and nontraditional studies. Previous years have seen studies that explored potential harms from holly and ivy, survival time of chocolates on hospital wards, and the question, “Were James Bond’s drinks shaken because of alcohol induced tremor?”
 

Study details

Ms. Costas and colleagues sought participants for their survey from online forums that included 4chan and Reddit, which are known for their controversial content posted by anonymous users. Data were also collected from ForoCoches and HispaChan, well-known Spanish online forums. These online sites were intentionally chosen because researchers thought “conspiracy beliefs would be more prevalent,” according to Ms. Costas.

Across the multiple forums, there were 1,494 participants. Of these, 209 participants were unvaccinated against COVID-19, 112 preferred alternatives rather than conventional medicine, and 62 reported that they believed the earth was flat or believed that humanoids take reptilian forms to manipulate human societies.

The team then sought to assess beliefs about actual and mythical (nonestablished) causes of cancer by presenting the participants with the closed risk factor questions on two validated scales – the Cancer Awareness Measure (CAM) and CAM–Mythical Causes Scale (CAM-MYCS).

Responses to both were recorded on a five-point scale; answers ranged from “strongly disagree” to “strongly agree.”

The CAM assesses cancer risk perceptions of 11 established risk factors for cancer: smoking actively or passively, consuming alcohol, low levels of physical activity, consuming red or processed meat, getting sunburnt as a child, family history of cancer, human papillomavirus infection, being overweight, age greater than or equal to 70 years, and low vegetable and fruit consumption.

The CAM-MYCS measure includes 12 questions on risk perceptions of mythical causes of cancer – nonestablished causes that are commonly believed to cause cancer but for which there is no supporting scientific evidence, the authors explain. These items include drinking from plastic bottles; eating food containing artificial sweeteners or additives and genetically modified food; using microwave ovens, aerosol containers, mobile phones, and cleaning products; living near power lines; feeling stressed; experiencing physical trauma; and being exposed to electromagnetic frequencies/non-ionizing radiation, such as wi-fi networks, radio, and television.

The most endorsed mythical causes of cancer were eating food containing additives (63.9%) or sweeteners (50.7%), feeling stressed (59.7%), and eating genetically modified foods (38.4%).

In this current age of mass misinformation and disinformation on the Internet, a tongue-in-cheek study that evaluated beliefs and attitudes toward cancer among conspiracy theorists and people who oppose vaccinations has received some harsh criticism.

The study, entitled, “Everything Causes Cancer? Beliefs and Attitudes Towards Cancer Prevention Among Anti-Vaxxers, Flat Earthers, and Reptilian Conspiracists: Online Cross Sectional Survey,” was published in the Christmas 2022 issue of The British Medical Journal (BMJ).

The authors explain that they set out to evaluate “the patterns of beliefs about cancer among people who believed in conspiracies, rejected the COVID-19 vaccine, or preferred alternative medicine.”

They sought such people on social media and online chat platforms and asked them questions about real and mythical causes of cancer.

Almost half of survey participants agreed with the statement, “It seems like everything causes cancer.”

Overall, among all participants, awareness of the actual causes of cancer was greater than awareness of the mythical causes of cancer, the authors report. However, awareness of the actual causes of cancer was lower among the unvaccinated and members of conspiracy groups than among their counterparts.

The authors are concerned that their findings suggest “a direct connection between digital misinformation and consequent potential erroneous health decisions, which may represent a further preventable fraction of cancer.”
 

Backlash and criticism

The study “highlights the difficulty society encounters in distinguishing the actual causes of cancer from mythical causes,” The BMJ commented on Twitter.

However, both the study and the journal received some backlash.

This is a “horrible article seeking to smear people with concerns about COVID vaccines,” commented Clare Craig, a British consultant pathologist who specializes in cancer diagnostics.

The study and its methodology were also harshly criticized on Twitter by Normal Fenton, professor of risk information management at the Queen Mary University of London.

The senior author of the study, Laura Costas, a medical epidemiologist with the Catalan Institute of Oncology, Barcelona, told this news organization that the naysayers on social media, many of whom focused their comments on the COVID-19 vaccine, prove the purpose of the study – that misinformation spreads widely on the internet.

“Most comments focused on spreading COVID-19 myths, which were not the direct subject of the study, and questioned the motivations of BMJ authors and the scientific community, assuming they had a common malevolent hidden agenda,” Ms. Costas said.

“They stated the need of having critical thinking, a trait in common with the scientific method, but dogmatically dismissed any information that comes from official sources,” she added.

Ms. Costas commented that “society encounters difficulty in differentiating actual from mythical causes of cancer owing to mass information. We therefore planned this study with a certain satire, which is in line with the essence of The BMJ Christmas issue.”

The BMJ has a long history of publishing a lighthearted Christmas edition full of original, satirical, and nontraditional studies. Previous years have seen studies that explored potential harms from holly and ivy, survival time of chocolates on hospital wards, and the question, “Were James Bond’s drinks shaken because of alcohol induced tremor?”
 

Study details

Ms. Costas and colleagues sought participants for their survey from online forums that included 4chan and Reddit, which are known for their controversial content posted by anonymous users. Data were also collected from ForoCoches and HispaChan, well-known Spanish online forums. These online sites were intentionally chosen because researchers thought “conspiracy beliefs would be more prevalent,” according to Ms. Costas.

Across the multiple forums, there were 1,494 participants. Of these, 209 participants were unvaccinated against COVID-19, 112 preferred alternatives rather than conventional medicine, and 62 reported that they believed the earth was flat or believed that humanoids take reptilian forms to manipulate human societies.

The team then sought to assess beliefs about actual and mythical (nonestablished) causes of cancer by presenting the participants with the closed risk factor questions on two validated scales – the Cancer Awareness Measure (CAM) and CAM–Mythical Causes Scale (CAM-MYCS).

Responses to both were recorded on a five-point scale; answers ranged from “strongly disagree” to “strongly agree.”

The CAM assesses cancer risk perceptions of 11 established risk factors for cancer: smoking actively or passively, consuming alcohol, low levels of physical activity, consuming red or processed meat, getting sunburnt as a child, family history of cancer, human papillomavirus infection, being overweight, age greater than or equal to 70 years, and low vegetable and fruit consumption.

“More than Jews have kept Shabbat, Shabbat has kept the Jews.” – Ahad Ha’am

You should all be well rested by now. After all, we’ve just come through the festive shutdown of the holiday season where all of your pumpkin/peppermint/marshmallow flavored coffees were sipped while walking around in your jimjams at 10 a.m. It was the time of year for you to take time off to get a proper rest and be energized to get back to work. Yet, I’m not feeling it from you.

So let’s talk about burnout – just kidding, that would only make it worse. “Burned-out’’ is a hackneyed and defective phrase to describe what many of us are feeling. We are not “destroyed, gutted by fire or by overheating.” No, we are, as one of our docs put it to me: “Just tired.” Ah, a much better Old English word! “Tired” captures it. It means to feel “in need of rest.” We are not ruined, we are just depleted. We don’t need discarding. We need some rest.

Ironically, this column, like most of mine, comes to you after my having written it on a Saturday and Sunday. I also just logged on to my EMR and checked results, renewed a few prescriptions, and answered a couple messages. If I didn’t, my Monday’s work would be crushingly heavy.

Maybe I need to be more efficient and finish my work during the week. Or maybe I need to realize that work has not let up since about 600 BCE and taking one day off each week to rest is an obligation to myself, my family and my community.

I wonder if I can choose Mondays.

A new hereditary test can determine whether a cancer-disposing gene was inherited from a patient’s father or mother without the need for parental DNA, potentially improving disease screening and management.

“The presence of parental imprints in regions of the genome has been known for a long time,” study author Peter Lansdorp, MD, PhD, of the BC Cancer Research Centre in Vancouver, said in an interview. In addition, the ability of a specific sequencing technology (Strand-seq) to generate a set of DNA variants that tend to be inherited together from a single parent has been documented in several studies.

“That these two pieces can be put together to assign alleles in a patient to one of the parents without studying the DNA of the parents is a major advance,” said Dr. Lansdorp.

Principal author Steven J.M. Jones, PhD, associate director of bioinformatics at BC Cancer Research Centre, explained, “for directing cascade genetic testing, the test could be used almost immediately, even as a research test. It just guides which side of the family to focus familial genetic testing efforts on and is internally validated by the patient’s variant and later confirmed by clinical testing in the family.”

Directing cascade genetic testing to one side of the family over the other could speed time to diagnosis of more carriers and allow for more efficient use of genetic counseling resources, Dr. Jones added, especially when parents are deceased or unavailable.

The study was published online in Cell Genomics.
 

Low error rate

Determining a parent of origin for hereditary variants “is essential to evaluate disease risk when a pathogenic variant has PofO effects, that is, when a patient’s risk of disease depends on from which parent it is inherited,” the authors wrote. An example is hereditary paraganglioma-pheochromocytoma syndrome as a result of pathogenic variants in SDHD or SDHAF2 genes. Individuals with the variants are at high risk of developing certain cancers, but only if a defective gene is inherited from their father. If inherited from their mother, there is no increased risk.

The new method relies on a technique called “phased DNA methylation” at maternally and paternally imprinted gene loci, as well as chromosome length phasing of DNA sequences.

The team used five human genome “trios” – two parents and the proband (the first person in a family to receive genetic testing or counseling for a suspected hereditary risk) – to pilot the approach. They showed that the method can correctly identify the PofO with an average mismatch error rate of 0.31% for single nucleotide variants and 1.89% for insertions or deletions (indels).

“We will need to validate this technology for different genes in real-world samples from individuals of diverse backgrounds,” said Dr. Jones. The first step is to validate the technology in scenarios with immediate clinical utility, like with SDHD, where lifelong medical management is affected by knowledge of whether the variant was inherited from the mother or father.

“We would also like to quickly validate this for common hereditary cancer genes, like BRCA1, BRCA2, and Lynch syndrome–associated genes, where prediction of PofO may improve low rates of genetic testing in family members by providing more accurate estimates of their risk to carry the familial variant.”

Challenges to moving the test to the clinic, Dr. Jones said, include scaling up the technology, demonstrating clinical and economic utility, compared with existing testing approaches, “and familiarizing clinicians with a new type of test that will routinely give this added dimension of information.”
 

‘Tremendously promising technology’

Pathologist Stephen Yip, MD, PhD, of the Vancouver Coastal Health Research Institute, who was not involved in the study but disclosed that he collaborates with the authors on other grant-funded projects, said in a comment that “this is a tremendously promising technology that has immediate practical implications in the investigation of PofO of a pathogenic locus, particularly when genetic material is available only from the proband.”

However, “rigorous validation against the current gold standard of short-reading, next-generation sequencing of trios is needed prior to clinical deployment,” he said. “This will take time and effort. However, the promise of this technology is worth the effort.

“Also, there is the possibility of uncovering novel genetics during testing, which could present an ethical dilemma,” he noted. “A robust consenting and ethical framework and early involvement of an ethicist would be helpful.”

Research in Dr. Lansdorp’s laboratory is funded by the Terry Fox Research Institute, the Canadian Institutes of Health Research, the Canadian Foundation for Innovation, and the government of British Columbia. Dr. Lansdorp, Dr. Jones, and Dr. Yip reported no relevant financial relationships.

Topical minoxidil is widely used to treat hair loss, but new findings suggest that a combination of oral and topical minoxidil could be effective for women with breast cancer who have experienced alopecia from anticancer treatment.

In a retrospective cohort study of women with breast cancer and anticancer therapy–induced alopecia, researchers found that combining low-dose oral minoxidil (LDOM) and topical minoxidil achieved better results than topical minoxidil alone and that the treatment was well tolerated. A total of 5 of the 37 patients (13.5%) in the combination therapy group achieved a complete response, defined as an improvement of alopecia severity from grade 2 to grade 1, compared with none of the 19 patients in the topical therapy–only group.

In contrast, none of the patients in the combination group experienced worsening of alopecia, compared with two (10.5%) in the topical monotherapy group.

The study was published online in the Journal of the American Academy of Dermatology. Topical minoxidil is approved by the Food and Drug Administration to treat androgenetic alopecia. Oral minoxidil is not approved for treating hair loss but has been receiving increased attention as an adjunctive therapy for hair loss, particularly for women. Oral minoxidil is approved for treating hypertension but at much higher doses.

An increasing number of studies have been conducted on the use of oral minoxidil for the treatment of female pattern hair loss, dating back to a pilot study in 2017, with promising results. The findings suggest that LDOM might be more effective than topical therapy, well tolerated, and more convenient for individuals to take.

Hypothesis generating

In a comment, Kai Johnson, MD, a medical oncologist who specializes in treating patients with breast cancer at the Ohio State University Comprehensive Cancer Center – Arthur G. James Cancer Hospital and Richard J. Solove Research Institute, Columbus, noted that the study, like most small-scale retrospective studies, is hypothesis generating. However, “I’d be hesitant to broadly recommend this practice of dual therapy – oral and topical minoxidil together – until we see a placebo-controlled prospective study performed demonstrating clinically meaningful benefits for patients.”

Another factor is the study endpoints. “While there was a statistically significant benefit documented with dual therapy in this study, it’s important to have study endpoints that are more patient oriented,” Dr. Johnson said. The most important endpoint for patients would be improvements “in the actual alopecia grade, which did occur in 5 of the 37 of dual-therapy patients, versus 0 topical minoxidil patients.”

George Cotsarelis, MD, chair of the department of dermatology and professor of dermatology at the University of Pennsylvania, Philadelphia, also weighed in. He questioned whether adding the topical therapy to oral minoxidil actually improved the results. “What was missing was a study arm that used the oral alone,” he said in an interview. “So we don’t know how effective the oral therapy would be by itself and if combining it with the topical is really adding anything.”

Oral minoxidil as a treatment for hair loss is gaining traction, and it’s clear that it is effective. However, the risk of side effects is higher, he said. “The risk isn’t that high with the low dose, but it can grow hair on places other than the scalp, and that can be disconcerting.” In this study, two women who took the oral drug reported edema, and one reported headache and dizziness. Hypertrichosis was reported by five patients who received the combination.
 

Study details

In the study, Jeewoo Kang, MD, and colleagues from the Seoul National University evaluated the efficacy of LDOM in 100 patients with breast cancer who had been diagnosed with persistent chemotherapy-induced alopecia (pCIA) and endocrine therapy–induced alopecia (EIA) at a dermatology clinic.

They conducted an analysis of medical records, standardized clinical photographs, and trichoscopic images to evaluate the alopecia pattern, severity, treatment response, and posttreatment changes in vertex hair density and thickness.

Compared with those with EIA alone, patients with pCIA were significantly more likely to have diffuse alopecia (P < .001), and they were more likely to have more severe alopecia, although this difference was not significant (P = .058). Outcomes were evaluated for 56 patients who were treated with minoxidil (19 with topical minoxidil alone and 37 with both LDOM and topical minoxidil) and for whom clinical and trichoscopic photos were available at baseline and at the last follow-up (all patients were scheduled for follow-up at 3-month intervals).

The results showed that those treated with 1.25-5.0 mg/d of oral minoxidil and 5% topical minoxidil solution once a day had better responses (P = .002) and a higher percentage increase in hair density from baseline (P = .003), compared with those who received topical minoxidil monotherapy.

However, changes in hair thickness after treatment were not significantly different between the two groups (P = .540).

In addition to the five (13.5%) cases of hypertrichosis, two cases of edema (5.4%), and one case of headache/dizziness (2.7%) among those who received the combination, there was also one report of palpitations (2.7%). Palpitations were reported in one patient (5%) who received topical monotherapy, the only adverse event reported in this group.

Dr. Johnson noted that, at his institution, a dermatologist is conducting a clinical trial with oncology patients post chemotherapy and endocrine therapy. “She is looking at a similar question, although she is comparing oral minoxidil to topical minoxidil directly rather than in combination.” There is also an active clinical trial at Northwestern University, Chicago, of LDOM alone for patients with chemotherapy-induced alopecia.

“So there is a lot of momentum surrounding this concept, and I feel we will continue to see it come up as a possible treatment option, but more data are needed at this time before it can become standard of care,” Dr. Johnson added.

No funding for the study was reported. The authors disclosed no relevant financial relationships.

Topical minoxidil is widely used to treat hair loss, but new findings suggest that a combination of oral and topical minoxidil could be effective for women with breast cancer who have experienced alopecia from anticancer treatment.

In a retrospective cohort study of women with breast cancer and anticancer therapy–induced alopecia, researchers found that combining low-dose oral minoxidil (LDOM) and topical minoxidil achieved better results than topical minoxidil alone and that the treatment was well tolerated. A total of 5 of the 37 patients (13.5%) in the combination therapy group achieved a complete response, defined as an improvement of alopecia severity from grade 2 to grade 1, compared with none of the 19 patients in the topical therapy–only group.

In contrast, none of the patients in the combination group experienced worsening of alopecia, compared with two (10.5%) in the topical monotherapy group.

The study was published online in the Journal of the American Academy of Dermatology. Topical minoxidil is approved by the Food and Drug Administration to treat androgenetic alopecia. Oral minoxidil is not approved for treating hair loss but has been receiving increased attention as an adjunctive therapy for hair loss, particularly for women. Oral minoxidil is approved for treating hypertension but at much higher doses.

An increasing number of studies have been conducted on the use of oral minoxidil for the treatment of female pattern hair loss, dating back to a pilot study in 2017, with promising results. The findings suggest that LDOM might be more effective than topical therapy, well tolerated, and more convenient for individuals to take.

Hypothesis generating

In a comment, Kai Johnson, MD, a medical oncologist who specializes in treating patients with breast cancer at the Ohio State University Comprehensive Cancer Center – Arthur G. James Cancer Hospital and Richard J. Solove Research Institute, Columbus, noted that the study, like most small-scale retrospective studies, is hypothesis generating. However, “I’d be hesitant to broadly recommend this practice of dual therapy – oral and topical minoxidil together – until we see a placebo-controlled prospective study performed demonstrating clinically meaningful benefits for patients.”

Another factor is the study endpoints. “While there was a statistically significant benefit documented with dual therapy in this study, it’s important to have study endpoints that are more patient oriented,” Dr. Johnson said. The most important endpoint for patients would be improvements “in the actual alopecia grade, which did occur in 5 of the 37 of dual-therapy patients, versus 0 topical minoxidil patients.”

George Cotsarelis, MD, chair of the department of dermatology and professor of dermatology at the University of Pennsylvania, Philadelphia, also weighed in. He questioned whether adding the topical therapy to oral minoxidil actually improved the results. “What was missing was a study arm that used the oral alone,” he said in an interview. “So we don’t know how effective the oral therapy would be by itself and if combining it with the topical is really adding anything.”

Oral minoxidil as a treatment for hair loss is gaining traction, and it’s clear that it is effective. However, the risk of side effects is higher, he said. “The risk isn’t that high with the low dose, but it can grow hair on places other than the scalp, and that can be disconcerting.” In this study, two women who took the oral drug reported edema, and one reported headache and dizziness. Hypertrichosis was reported by five patients who received the combination.
 

Study details

In the study, Jeewoo Kang, MD, and colleagues from the Seoul National University evaluated the efficacy of LDOM in 100 patients with breast cancer who had been diagnosed with persistent chemotherapy-induced alopecia (pCIA) and endocrine therapy–induced alopecia (EIA) at a dermatology clinic.

They conducted an analysis of medical records, standardized clinical photographs, and trichoscopic images to evaluate the alopecia pattern, severity, treatment response, and posttreatment changes in vertex hair density and thickness.

Compared with those with EIA alone, patients with pCIA were significantly more likely to have diffuse alopecia (P < .001), and they were more likely to have more severe alopecia, although this difference was not significant (P = .058). Outcomes were evaluated for 56 patients who were treated with minoxidil (19 with topical minoxidil alone and 37 with both LDOM and topical minoxidil) and for whom clinical and trichoscopic photos were available at baseline and at the last follow-up (all patients were scheduled for follow-up at 3-month intervals).

Leave the mouthwash. Take the yogurt

Most of us have experienced some sort of bad breath. It’s common in the morning right after waking up, but it also may be a sign for underlying medical issues like dental problems or acid reflux. Wherever it comes from, we always want to get rid of it. A recent meta-analysis in BMJ Open may have found the answer in some common foods.

For those with halitosis, the basic problem is that the bacteria in their mouths are not happy about where they are. The researchers looked at 130 studies and found seven that suggested fermented food has some effect in combating bad breath.

Now when we say fermented food, we’re not talking about that science project waiting to happen in the back of the refrigerator. Think yogurt, sourdough bread, or miso soup. Anything that contains probiotic bacteria.

Matthew J. Messina, DDS, assistant professor of dentistry at Ohio State University, who was not involved with the study, told Healthline that “the whole idea behind probiotics is [bacteria replacement]. Supplant the ‘bad guys’ with the ‘good guys,’ then we’ll end up with a better result.” Essentially balancing the scales in your mouth.

It may not be a long-term solution, Dr. Messina said, but the short-term data are positive. So if you experience bad breath from time to time, try a little bowl of yogurt instead of chewing gum. If nothing else, the bacteria in your mouth will thank you.

You can talk the silly talk, but can you walk the silly walk?

The Ministry of Silly Walks sketch from Monty Python is an enduring comedy classic, and one of surprising relevance for doctors. After all, this isn’t the first time a study has analyzed the unusual strides of Mr. Putey and Mr. Teabag.

The BMJ Christmas edition truly is the gift that keeps on giving. For this plunge into the Flying Circus, the study authors recruited a small group of fairly average adults and had them walk normally around a track for 5 minutes, monitoring their oxygen intake and energy expenditure. After that, the study participants imitated Mr. Putey’s walk and then Mr. Teabag’s.

In the sketch, Mr. Teabag notes that Mr. Putey’s walk is “not particularly silly,” which is borne out in the research. When imitating Mr. Putey’s walk, oxygen intake and energy expenditure were barely higher than a normal walk, not enough to achieve a meaningful difference. Hopefully he’ll get that government grant to further develop his silly walk, because right now Mr. Putey’s walk simply doesn’t cut it.

Mr. Teabag’s walk is a different story and the very image of inefficiency. Oxygen intake was 2.5 times higher than during the normal walk, and energy expenditure was noticeably higher (8 kcal in men and 5.2 kcal in women). In fact, the walk was so inefficient and its effect so drastic it actually reached the level of vigorous exercise. Thanks to this, the study authors noted that just 11 minutes a day of walking like Mr. Teabag would be enough to reach the general goal of 75 minutes of vigorous exercise per week. Boosting that to 12-19 minutes would increase daily energy expenditure by 100 kcal.

The study authors wrote, “Had an initiative to promote inefficient movement been adopted in the early 1970s, we might now be living among a healthier society. Efforts to promote higher energy – and perhaps more joyful – walking should ensure inclusivity and inefficiency for all.” We think they just advocated for a real-life Ministry of Silly Walks. Well, there have been worse ideas. Just look at Twitter.
 

When efficient gut microbes go bad

With the latest news from the Ministry of Silly Walks, is it time for humans to embrace all things inefficient? Maybe.

Turns out that individuals with more efficient digestive systems – those that extract more energy from the fuel supplied to them by the busy mouths above – tend to gain more weight than those with less efficient guts, even when they eat the same food, according to a recent study published in Microbiome.

The researchers took a look at the composition of gut microbes in a group of 85 volunteers and found that about 40% had microbiomes dominated by Bacteroides bacteria, which are more effective at extracting nutrients from food. That group also weighed 10% more on average, amounting to an extra 9 kg.

In a rather blatant demonstration of efficiency, the investigators also measured the speed of the participants’ digestion, as they had hypothesized that those with the longest digestive travel times would be the ones who harvested the most nutrition from their food. That was not the case.

The study subjects with the most efficient gut bacteria “also have the fastest passage through the gastrointestinal system, which has given us something to think about,” senior author Henrik Roager of the University of Copenhagen said in a written statement.

You know what gives us something to think about? Stool energy density and intestinal transit time and faecal bacterial cell counts, that’s what. Ick. Sometimes science is gross.

Here’s another thought, though: Seeing faecal instead of fecal is kind of funny to our American eyes, but adding that extra letter is also inefficient, which could mean that it’s good. So, in the spirit of embracing the inefficient as a new year begins, we’re resolving to wrap our editorial arms around faecal and the faeces it represents. Well, not literally, of course. More like we’re embracing the spirit of faeces.

Congress averted bigger reductions in Medicare’s future payments for clinicians in its massive, year-end spending bill, but physicians will still see a 2% cut in a key payment variable in 2023.

The bill also authorizes new policies regarding accelerated drug approvals and substance use disorder treatment.

The House voted 225-201 to clear a wide-ranging legislative package, known as an omnibus, for President Joe Biden’s signature. The Senate voted 68-29 to approve the measure.

Clinicians had been facing as much as 8.5% in cuts to certain factors that set their Medicare payment. The American Medical Association credited an advocacy campaign it joined with more than 150 organizations with fending off the much-feared reimbursement cuts. The 2% trim for 2023 will decline to 1.25% for 2024.

These reductions will hit as many clinicians face the toll on rising costs for running their practices, as Congress has not included inflation-based payment adjustments in Medicare’s physician payment rule, the AMA said.

“Congress must immediately begin the work of long-overdue Medicare physician payment reform that will lead to the program stability that beneficiaries and physicians need,” AMA President Jack Resneck, MD, said in a statement.

While the omnibus bill blocks 6.5% of Medicare payment cuts originally slated to take effect in 2023, it still puts “untenable strain” on primary care clinicians, said Tochi Iroku-Malize, MD, MPH, president of the American Academy of Family Physicians, in a statement.

“However, we’re pleased to see several provisions that will improve access to care, including bolstering mental health services, extending telehealth, and expanding Medicaid and CHIP coverage,” Dr. Iroku-Malize added.
 

New health care policies in omnibus

Lawmakers adopted many health care policy changes in the omnibus package, which contained 12 overdue spending bills for fiscal year 2023. (Much of the federal government has been funded through stop-gap measures since this budget year began on Oct. 1.) The final measure runs to more than 4,100 pages in PDF form.

House Energy and Commerce Chairman Frank Pallone Jr. (D-NJ) said the health care provisions will:

• Expand patient access to opioid addiction treatment by making it easier for clinicians to dispense buprenorphine for opioid use disorder maintenance or detoxification treatment
• Require health care providers to complete a training requirement on identifying and treating patients with substance use disorders
• Guarantee 12 months of continuous Medicaid coverage for 40 million children
• Provide 2 years of additional Children’s Health Insurance Program (CHIP) funding
• Permanently extend the option for states to offer 12 months of Medicaid coverage to new mothers
• Continue Medicare’s expanded access to telehealth by extending COVID-19 telehealth flexibilities through Dec. 31, 2024.

FDA’s accelerated approval

The omnibus also will shorten the period of uncertainty patients and clinicians face with medicines cleared under the accelerated approval pathway.

The Food and Drug Administration uses accelerated approvals to give conditional clearances to medicines for fatal and serious conditions based on limited evidence signaling a potential benefit. Companies are expected to continue research needed to prove whether promising signals, such as stemming tumor growth, benefits patients.

Concerns have mounted when companies delay confirmatory trials or try to maintain accelerated approvals for drugs that fail those trials.

Mr. Pallone said the omnibus contains provisions that:

• Require the FDA to specify conditions for required post-approval studies
• Authorize the FDA to require post-approval studies to be underway at the time of approval or within a specified time period following approval.
• Clarify and streamline current FDA authority to withdraw approvals when sponsors fail to conduct studies with due diligence.

Reshma Ramachandran, MD, MPP, MHS, who serves as the chair of the Doctors for America’s FDA Task Force, told this news organization that she was pleased to see these provisions pass. She had been disappointed they were not included earlier this year in the latest Prescription Drug User Fee Act reauthorization.

The provisions in the omnibus make “clear what steps the FDA can take to remove an unproven drug off the market should manufacturers fail to complete these studies or demonstrate meaningful clinical benefit,” Dr. Ramachandran wrote in an email.

Dr. Ramachandran said she hopes lawmakers build on these steps in the future. She suggested Congress add a mandate to require drug labels to clearly state when the FDA is still waiting for evidence needed to confirm benefits of medicines cleared by accelerated approval.

“Nevertheless, Congress in including and, hopefully, passing these reforms has made it clear that drug companies need to provide meaningful evidence that their accelerated approval drugs work in patients and FDA can take action to protect patients should this not occur,” Dr. Ramachandran wrote.

The House voted 225-201 to clear a wide-ranging legislative package, known as an omnibus, for President Joe Biden’s signature. The Senate voted 68-29 to approve the measure.

Clinicians had been facing as much as 8.5% in cuts to certain factors that set their Medicare payment. The American Medical Association credited an advocacy campaign it joined with more than 150 organizations with fending off the much-feared reimbursement cuts. The 2% trim for 2023 will decline to 1.25% for 2024.

These reductions will hit as many clinicians face the toll on rising costs for running their practices, as Congress has not included inflation-based payment adjustments in Medicare’s physician payment rule, the AMA said.

“Congress must immediately begin the work of long-overdue Medicare physician payment reform that will lead to the program stability that beneficiaries and physicians need,” AMA President Jack Resneck, MD, said in a statement.

While the omnibus bill blocks 6.5% of Medicare payment cuts originally slated to take effect in 2023, it still puts “untenable strain” on primary care clinicians, said Tochi Iroku-Malize, MD, MPH, president of the American Academy of Family Physicians, in a statement.

“However, we’re pleased to see several provisions that will improve access to care, including bolstering mental health services, extending telehealth, and expanding Medicaid and CHIP coverage,” Dr. Iroku-Malize added.
 

New health care policies in omnibus

Lawmakers adopted many health care policy changes in the omnibus package, which contained 12 overdue spending bills for fiscal year 2023. (Much of the federal government has been funded through stop-gap measures since this budget year began on Oct. 1.) The final measure runs to more than 4,100 pages in PDF form.

House Energy and Commerce Chairman Frank Pallone Jr. (D-NJ) said the health care provisions will:

• Expand patient access to opioid addiction treatment by making it easier for clinicians to dispense buprenorphine for opioid use disorder maintenance or detoxification treatment
• Require health care providers to complete a training requirement on identifying and treating patients with substance use disorders
• Guarantee 12 months of continuous Medicaid coverage for 40 million children
• Provide 2 years of additional Children’s Health Insurance Program (CHIP) funding
• Permanently extend the option for states to offer 12 months of Medicaid coverage to new mothers
• Continue Medicare’s expanded access to telehealth by extending COVID-19 telehealth flexibilities through Dec. 31, 2024.

FDA’s accelerated approval

The omnibus also will shorten the period of uncertainty patients and clinicians face with medicines cleared under the accelerated approval pathway.

The Food and Drug Administration uses accelerated approvals to give conditional clearances to medicines for fatal and serious conditions based on limited evidence signaling a potential benefit. Companies are expected to continue research needed to prove whether promising signals, such as stemming tumor growth, benefits patients.

Concerns have mounted when companies delay confirmatory trials or try to maintain accelerated approvals for drugs that fail those trials.

Mr. Pallone said the omnibus contains provisions that:

• Require the FDA to specify conditions for required post-approval studies
• Authorize the FDA to require post-approval studies to be underway at the time of approval or within a specified time period following approval.
• Clarify and streamline current FDA authority to withdraw approvals when sponsors fail to conduct studies with due diligence.

Reshma Ramachandran, MD, MPP, MHS, who serves as the chair of the Doctors for America’s FDA Task Force, told this news organization that she was pleased to see these provisions pass. She had been disappointed they were not included earlier this year in the latest Prescription Drug User Fee Act reauthorization.

The provisions in the omnibus make “clear what steps the FDA can take to remove an unproven drug off the market should manufacturers fail to complete these studies or demonstrate meaningful clinical benefit,” Dr. Ramachandran wrote in an email.

Dr. Ramachandran said she hopes lawmakers build on these steps in the future. She suggested Congress add a mandate to require drug labels to clearly state when the FDA is still waiting for evidence needed to confirm benefits of medicines cleared by accelerated approval.

“Nevertheless, Congress in including and, hopefully, passing these reforms has made it clear that drug companies need to provide meaningful evidence that their accelerated approval drugs work in patients and FDA can take action to protect patients should this not occur,” Dr. Ramachandran wrote.

Breast cancer treatments have made great strides in recent years with significant reductions in overall mortality. However, the incidence of breast cancer has increased just slightly in recent years after a dip in the early 2000s.

“The good news is that mortality is decreasing, but it still remains high. We still have a long way to go to tackle this problem of breast cancer incidence as well as the number of deaths,” said Angela DeMichele, MD, co-leader of the breast cancer research program at the University of Pennsylvania’s Abramson Cancer Center. She participated in a session on obstacles in breast cancer treatment held in December at the San Antonio Breast Cancer Symposium. She joined other oncologists in outlining key challenges that need to be addressed to improve breast cancer diagnosis and treatment.

They highlighted six obstacles: The need for more prevention/early detection strategies; the underutilization of artificial intelligence; underuse of precision oncology such as targeted therapies; the need for innovation in clinical trials; a widening gap in cancer disparities; and the need to align incentives and funding for research collaboration, training, and retention.

Since 2012, the Food and Drug Administration has approved 20 new therapeutics to treat breast cancer. Nadia Harbeck, MD, PhD, director of the breast center at LMU University Hospital, Munich, said that the development of new therapies has in a way become a victim of its own success. Therapies and survival have improved, making it harder to compare novel therapies to the standard of care and prove a benefit. Treatment guidelines are changing so quickly that clinical trials are sometimes obsolete by the time they are published because of changes to the standard of care. That places a need on more real-world evidence that can be designed to be useful in the clinic, and AI can help here. “We need to convince regulators to act upon cleverly planned real world evidence analysis. You can randomize them, you can use registries, and you should also be able to change labels because of [new] data,” Dr. Harbeck said.

There are many risk factors that drive breast cancer, and it is very heterogeneous, said Christine Ambrosone, PhD, chair of the department of cancer prevention and control at Roswell Park Comprehensive Cancer Center, Buffalo, N.Y. She called for identifying patients who are at risk for a poor prognosis, such as patients with hormone receptor–negative breast cancer, high-grade, and triple-negative breast cancer. Otherwise there is a risk of overtreatment of low-risk tumors, which could potentially be identified with new tools in precision oncology such as liquid biopsy tests, also known as multicancer early detection tests. These tests can detect cancers long before they become symptomatic. The first such test was launched this year and many more are in clinical trials.

Regina Barzilay, PhD, professor and expert in the use of artificial intelligence in health at the Massachusetts Institute of Technology, pointed out that machine learning is used in many fields, but hardly at all in breast cancer. It could be applied to data on biomarkers and other factors collected from retrospective analyses and clinical trials. She added that machine learning is often applied to biochemistry and single cell analysis of other tumor types, but rarely in breast cancer. “It is severely underutilized,” Dr. Barzilay said. One challenge is that researchers are not necessarily familiar with the techniques of machine learning and AI. Another issue is that breast cancer data are not easy to share and may not be readily available to AI researchers. “An investment in interchangeable data is crucially important,” she said.

Artificial intelligence could assist in identifying and modeling factors that contribute to cancer risk by teasing apart complicated relationships, such as the association between pregnancy, breastfeeding, and breast cancer risk. Pregnancy reduces the risk of hormone receptor–positive disease, but increases the risk of hormone receptor–negative disease.

Another key challenge is the underuse of “omics” technologies, which measure large scale patterns in biological characteristics such as gene variation or protein expression. That has roots in the history of breast cancer being considered as a separate entity from other solid tumors such as lung or pancreatic cancer. Fabrice André, MD, PhD, an oncologist with Gustave Roussy Cancer Center, France, emphasized that breast cancer shouldn’t be considered an entity when it’s metastatic. Instead, tumors should be defined by molecular characteristics they share. He anticipates a personalized medicine future where academic and industry groups collaborate to create an individualized therapy for patients based on genetic factors.
 

Access to therapies for all patients

Novel and effective therapies can make a difference only if patients have access to them, and a key obstacle to improving breast cancer care is racism and inequities in health care. “We have to acknowledge that there is racism in medicine. I think once we acknowledge that, then we can look at things in our practices that we need to change. We can think very broadly and look at things that perhaps disadvantage one population over another,” said Lori Pierce, MD, a radiation oncologist with the University of Michigan, Ann Arbor.

Dr. Pierce also emphasized the need to recruit more underrepresented groups to participate in clinical trials. For example, of six breast cancer clinical trials – for margetuximab (Margenza), sacituzumab govitecan (Trodelvy), tucatinib (Tukysa), trastuzumab deruxtecan (Enhertu), alpelisib (Piqray), and talazoparib (Talzenna), only a small percentage included Black, Asian, and Hispanic women. For trastuzumab deruxtecan, which is widely recognized as a best-in-class HER2-targeting antibody drug conjugate, 51% were White, 42% Asian, 6% Hispanic, and 3% Black. For sacituzumab govitecan, a blockbuster drug for triple-negative breast cancer (TNBC), an aggressive subtype of breast cancer that disproportionately affects Black women, only 7% of women enrolled in clinical trials were Black. In clinical trials for margetuximab, approved to treat HER2-positive breast cancer, 80% of participants were White, 5% Black, 6% Asian, and 9% Hispanic.

There is a perception that minorities may be unwilling to participate in clinical trials, but that’s not true, according to Patty Spears, a research manager of the Patient Advocates for Research Council at the University of North Carolina. “We know that there are data that clearly show that patients will go on clinical trials at the same rate, whether they’re Black, White, Asian, or whatever. You have to be able to have them in your system and ask them to go on trial,” she said.

Another panelist told a personal anecdote to illustrate the point. Matthew Ellis, MD, PhD, recalled that he spent 13 years at Washington University in St. Louis, serving one of the more segregated cities in the United States. The city hospital closed, and Washington University and the Siteman Cancer Center signed a contract to treat the underserved population that was suddenly without a source of care. “Subsequent to that, we over-accrued relative to the population of African American patients. What that taught me is it’s nothing to do with the lack of willingness of African Americans to participate in clinical trials. Quite the opposite. It’s the question of access to clinical trials, access to great care, and not creating health care systems that segregate patients into places where they’re not getting access,” he said.
