[caption id="attachment_71691" align="alignleft" width="150"]MedicalResearch.com Interview with:Alexa T. Diianni, MBS Department of Medical Education Geisinger College of Health Sciences Scranton, PA 19409 MedicalResearch.com: What is the background for this study? During a previous study, my research team and I examined the financial conflicts of interest (COIs) between industry and academia- namely those that exist between authors of The American Psychiatric Association’s Diagnostic and Statistical Manual of Mental Disorders (DSM), and industry (1). The DSM is a diagnostic tool widely used for the diagnosis of psychiatric disorders, and is thus of interest in assessing COIs (1,2). We previously found that authors of the DSM-5-TR had received over $14.2m in undisclosed payments from industry (1). Our current study examines the gender and geographic disparities of the DSM-5-TR authors, in relation to these payments. While previous investigations have evaluated financial COIs in recent editions of the DSM (3,4), the demographic information of its authors has not yet been examined. Equitable representation of DSM authors is paramount as this manual serves a diverse population across the United States and beyond. It is important that the authorship of this manual be reflective of the population in which it serves, as there have been reported differences in both the type and prevalence of psychiatric care sought out by gender, as well as varying clinical treatment by geographic location (5-8). MedicalResearch.com: What are the main findings? Of the 225 physicians that were identified as contributors to the DSM-5-TR task force, panels, and cross-cutting review groups, 116 contributors met the inclusion criteria of being a US-based physician with an active National Provider Identifier. Of these included individuals, 69.8% were men and 30.2% were women. Just three states accounted for 43.9% of contributors (New York, 17.2%; California, 14.7%; Massachusetts, 12.1%), while twenty-three states received no author representation. Of the total $14.6m in industry payments received by contributors, $13.2m (91.8%) was received by male contributors. Male contributors thus received an average of $287k in payment, while female contributors received $72k. MedicalResearch.com: What should readers take away from your report? Due to the prevalent use of the DSM, it is important that transparency regarding financial conflicts of interest exists, with COIs minimized moving forward to avoid implicit bias and pro-industry thought (1,9-15). Furthermore, it is important that future editions of the DSM be representative of the population in which it serves. This can be attained by selecting an adequate proportion of male and female contributors for the DSM, which may provide more robust perspectives on current diagnoses. Additionally, representation of contributors from all regions across the US will allow for a more diverse and informed perspective on diagnostic criteria, allowing for improved public health and patient care within the United States. MedicalResearch.com: What recommendations do you have for future research as a result of this study? As gender and geographic disparities were shown to be significant through this study, I believe it would be interesting to address additional areas of demographic disparities among authors. Additional areas to examine may include non-US-based physicians, non-MD/DO authors, as well as ethnic and racial disparities among authors. Finally, similar studies may be applied to additional clinical and diagnostic tools. Diagnostic manuals, such as the DSM, written by a diverse set of individuals, would provide unique perspectives that best reflect the population as a whole, and in turn, benefit patient care. For this reason, it is important that diagnostic manuals, such as the DSM, include a diverse set of authors that can provide adequate input regarding the patient population it serves. MedicalResearch.com: Is there anything else you would like to add? This research received no external funding. First author (AD) is employed by PerkinElmer, working on assignment at GlaxoSmithKline (2023-Present), outside of the submitted work; Last author (BP) contributed to an osteoarthritis research team supported by Pfizer and Eli Lilly (2019-21) and received grants from the Pennsylvania Academic Clinical Research Center, outside of the submitted work.

Author Interviews, Gender Differences, JAMA, University of Michigan / 14.02.2025

MedicalResearch.com Interview with: [caption id="attachment_66556" align="alignleft" width="200"]Farrah Madanay, PhDPostdoctoral Research Fellow Center for Bioethics and Social Sciences in Medicine Michigan Medicine University of Michigan Dr. Madanay[/caption] Farrah Madanay, PhD Postdoctoral Research Fellow Center for Bioethics and Social Sciences in Medicine Michigan Medicine University of Michigan MedicalResearch.com: What is the background for this study? Response: Patients are increasingly using online forums to evaluate their physicians, with not only star ratings but also written narrative reviews. These reviews tend to fall into two dimensions: interpersonal manner, which includes comments about the physician’s attitude, behavior, and communication; and technical competence, which includes comments about the physician’s knowledge, skill, and outcomes. These two dimensions are important for patient-centered care and align with research from social psychology. Whereas prior studies have revealed gender differences in workplace assessments and overall star ratings of physicians, little is known about physician gender differences in patients’ online written reviews. We were curious whether physician gender differences were prevalent in patients’ written reviews and consistent across physician specialties, from generalists, like primary care physicians, to proceduralists, like surgeons. We collected physician profile, rating, and review data from one of the largest commercial physician rating and review websites. We focused on physicians from three primary care specialties (family medicine, internal medicine, and pediatrics), and three surgical specialties (general surgery; orthopedic surgery; and cosmetic, plastic, and reconstructive surgery). Our final sample included 345,053 online reviews received by 167,150 U.S. physicians between 2015 and 2020. We used hand-coded reviews to train an advanced natural language processing algorithm to classify all reviews for the presence and valence of patients’ comments of physicians’ interpersonal manner and technical competence. We then conducted multilevel logistic regressions to analyze differences by female or male physician gender in interpersonal manner and technical competence comments and whether those comments were associated with review star ratings.

Response: Prior studies have found that female and male physicians practice medicine differently. For example, female physicians are, on average, more likely to abide by clinical guidelines and spend more time listening to patients. However, evidence was limited as to whether such differences have clinically meaningful impact on patients’ health outcomes, which was the aim of this study.

MedicalResearch.com Interview with: [caption id="attachment_61209" align="alignleft" width="150"]Jianzhi "George" ZhangMarshall W. Nirenberg Collegiate Professor Department of Ecology and Evolutionary Biology University of Michigan Ann Arbor, MI 48109-1085 Dr. Zhang[/caption] Jianzhi "George" ZhangMarshall W. Nirenberg Collegiate ProfessorDepartment of Ecology and Evolutionary BiologyUniversity of MichiganAnn Arbor, MI 48109-1085 MedicalResearch.com: What is the background for this study? Response: A few percent of humans perform same-sex sexual behavior (SSB), a trait that is partially heritable. Because SSB leads to fewer children, the stable maintenance of SSB-associated alleles in populations has been a long-standing Darwinian paradox. A number of hypotheses have been proposed to resolve this paradox, but most of them lack clear empirical evidence. One version of the antagonistic pleiotropy hypothesis posits that SSB-associated alleles are subject to heterosexual advantage. Specifically, it was found that SSB-associated alleles are associated with more sexual partners when in heterosexuals (individuals of exclusive opposite-sex sexual behavior), which could lead to more offspring, potentially compensating the reduced reproduction of SSB individuals. While the above mechanism has likely worked in premodern societies, our recent study (PNAS 2023) found that it is no longer working in the modern United Kingdom, because the widespread use of contraception has decoupled the number of offspring from the number of sexual partners in heterosexuals.

Response: Transgender patients often experience pronounced healthcare disparities compared to their cisgender counterparts. Disparities in the treatment of transgender patients resulting from deficiencies in cultural competency perpetuate poor health outcomes, such as suicide, substance misuse, depression, harassment, and victimization. Individuals within the transgender community often face systemic barriers within the medical field, including a lack of comprehensive access to health insurance, discrimination from providers, and incompetent provider training in transgender-specific health needs. This report evaluated the changes in knowledge, attitudes, and beliefs of the psychosocial and medical needs of the transgender community among first-year undergraduate medical students that attended the Northeastern Pennsylvania Trans Health Conference. Our broader goal is to develop and refine longitudinal interventions to improve skills and sensitivity of future physicians to provide compassionate and competent gender diverse and transgender healthcare.

  • We have been studying how the primary treating surgeons sociocultural characteristics impact the recovery of patients they are looking after.
  • Specifically, we have been studying the effect of surgeon sex on outcomes such as death, complications and readmission after common and complex surgeries. These are outcomes that are important to patients and the health system.
  • Previously, we showed that patients with a female surgeon had better short term (30 day) outcomes than similar patients having surgery with a man. This study asked the question of whether the sex of a patient’s surgeon affects patients’ longer term outcomes at 90 days and 1 year, after surgery.

Wright, MD, FACOG, FACS Sol Goldman Associate Professor Chief, Division of Gynecologic Oncology Vice Chair of Academic Affairs, Department of Obstetrics and Gynecology Columbia University College of Physicians and Surgeons New York, New York 10032 MedicalResearch.com: What is the background for this study? Response: There is growing recognition that gender-affirming surgery (GAS) is safe and that the procedures are associated with favorable long term outcomes. Prior work has explored the use of inpatient procedures and shown that the rates of GAS have risen, but there is little contemporaneous data to examine more recent inpatient and outpatient use of GAS. This is particularly important as changes in insurance regulations may have increased access for these procedures. We examined temporal trends in performance of inpatient and outpatient GAS and examined age-specific trends in the types of procedures performed over time.

MedicalResearch.com Interview with: [caption id="attachment_60512" align="alignleft" width="132"]FRANCESCA GALBIATI Dr. GALBIATI[/caption] Francesca Galbiati, MD Clinical/Research fellow in Endocrinology Massachusetts General Hospital MedicalResearch.com: What is the background for this study? Response:  Arginine-vasopressin (AVP) is a neurohormone well known for its role in water balance regulation. It promotes renal water absorption in the kidney, to maintain normal sodium levels in the blood via a tightly controlled osmotic regulation. Besides AVP classical role, data have shown that AVP effects extend beyond water balance regulation. Animal studies have shown that AVP has metabolic effects, including reducing food intake, inducing lipolysis, and promoting muscle regeneration in male mice. Furthermore, AVP is regulated differently in males and females, and affects cognition differently across sexes, a phenomenon called sexual dimorphism. However, it is unknown whether its dimorphism translates to metabolism. Also, findings on AVP metabolic role are inconsistent, possibly due to the opposing effects of AVP at different receptor subtypes, which regulation is still largely unknown. We performed this study to better investigate AVP metabolic role, and explore sex differences. We hypothesized that AVP would be positively associated with BMI, adiposity, and lean mass (acting as a signal of energy availability). We also predicted that relationships between AVP and body composition measures would differ by sex. We used the AVP area under the curve around a standardized meal to better capture repeated measures in response to food intake (that directly impacts energy availability). This also allowed to avoid the possible risk of fluctuating AVP levels due to possible pulsatile secretion.
Alzheimer's - Dementia, Author Interviews, Brigham & Women's - Harvard, Gender Differences, JAMA, Menopause / 03.04.2023

MedicalResearch.com Interview with: [caption id="attachment_60274" align="alignleft" width="150"]Rachel Buckley, PhD​Assistant Professor Department of Neurology Massachusetts General Hospital/Harvard Medical School Dr. Buckley[/caption] Rachel Buckley, PhD ​Assistant Professor Department of Neurology Massachusetts General Hospital/Harvard Medical School MedicalResearch.com: What is the background for this study? Response: While a fair amount of studies have focused on the effects of menopause and hormone therapy on risk of dementia, far fewer studies have tested their association with the biology of Alzheimer’s disease, namely amyloid and tau. This is critical to know given that it still remains unclear what might be the driving mechanism of the menopause transition on risk for dementia. This is what our study set out to investigate. This study is one of the first to report a link between women’s age at menopause and tau in the brain, which we measured with positron emission tomography neuroimaging. We found that in multiple areas of the brain that tend to be most likely to show higher tau in women than men, women with earlier age at menopause and elevated levels of amyloid showed higher levels of tau than those who reported an average age at menopause (~50 years in the United States). Women who reported premature menopause (<40 years at menopause onset) exhibited a much higher risk of tau in the brain. This supports the notion that longer exposure to estrogen throughout life might be protective against Alzheimer’s disease.

Response: It is well-documented that women undergoing CABG have higher mortality and morbidity when compared with men. They are referred to surgery later than men, with more cardiovascular risk factors than men, and present more frequently with heart failure or in non-elective settings. However, overall CABG outcomes have improved over time, and so we sought to evaluate national trends in outcomes specifically in women.

MedicalResearch.com Interview with: [caption id="attachment_60052" align="alignleft" width="125"]Michael Liu, MPhilRhodes Scholar,MPhil in Evidence-Based Social Intervention and Policy Evaluation. Harvard Medical School Boston, Massachusetts Michael Liu[/caption] Michael Liu, MPhil Rhodes Scholar,MPhil in Evidence-Based Social Intervention and Policy Evaluation. Harvard Medical School Boston, Massachusetts   MedicalResearch.com: What is the background for this study? Response: Over the past few decades, research has shown that lesbian, gay, and bisexual (LGB) individuals have worse health outcomes and face unique challenges related to their experiences and costs of care. These disparities are driven by “minority stress” associated with belonging to a marginalized group. Such stressors erode health through a range of structural and interpersonal forces, including employment discrimination, family rejection, and internalized stigma One early analysis established national baseline estimates for LGB health outcomes using 2013-2014 National Health Interview Survey (NHIS) data. Since then, there have been substantial shifts in social policy and public opinion that may have differentially affected sexual minority subgroups. The US Supreme Court decision in Obergefell v. Hodges guaranteed the constitutional right to same-sex marriage across all states. Over the last decade, states have expanded rights and protections for LGB populations related to employment and housing discrimination, sexual orientation conversion efforts, HIV criminalization, and religious exemptions. Public support for LGB-related issues has also been increasing with more representation in media, uptake of LGB-affirming policies, and advocacy efforts. No studies have assessed national trends in health status or healthcare access among specific sexual minority subgroups amid the rapidly shifting sociocultural and policy landscape. Thus, we sought out to evaluate if and how health status and healthcare access have changed between 2013 and 2018 in the US among LGB adults, and whether differences relative to their heterosexual counterparts have changed over time.
Author Interviews, Biomarkers, Gender Differences, Kidney Disease, NEJM, Race/Ethnic Diversity / 26.01.2023

MedicalResearch.com Interview with: [caption id="attachment_59955" align="alignleft" width="150"]Prof. dr. Hans Pottel Prof. dr. Pottel[/caption] Prof. dr. Hans Pottel KU Leuven Kulak Department of Public Health and Primary Care Belgium MedicalResearch.com: What is the background for this study? Response:  The glomerular filtration rate (GFR) is used to diagnose patients with chronic kidney disease and is also used to adjust the dose of drugs that are eliminated by the kidneys. An accurate estimation of GFR is considered of importance in the management of kidney health in patients. In 2021 we published a new serum creatinine based equation, called the European Kidney Function Consortium (EKFC) equation (Pottel H. et al, Development and Validation of a Modified Full Age Spectrum Creatinine-Based Equation to Estimate Glomerular Filtration Rate : A Cross-sectional Analysis of Pooled Data. Ann Intern Med (2021) 174: 183-191): EKFC-eGFR = 107.3 / [Biomarker/Q]a x [0.990(Age – 40) if age > 40 years] With a = 0.322 if Biomarker/Q is less than 1, and a = 1.132 if Biomarker/Q is 1 or more. The equation can easily be interpreted: the leading coefficient equals the glomerular filtration rate (GFR) of 107.3 mL/min/1.73m², which is the average GFR in healthy children (aged > 2 years), adolescents and young adults. The average healthy GFR remains constant until the age of 40 years, and starts decreasing beyond that age. The GFR is inversely related to the ‘rescaled’ biomarker. The rescaling factor (Q) is the average biomarker value for healthy people of a specific population (e.g. children, adult men, adult women, white people, black people, …). Biomarker/Q equals ‘1’ for the average healthy person, corresponding with eGFR = 107.3 mL/min/1.73m² (up to 40 years of age). It should be noted that for serum creatinine, the Q-value depends on sex and race. Our hypothesis was that the above equation is valid for any renal biomarker, on the condition that the biomarker is appropriately scaled. We showed that the same equation was able to estimate GFR from 2 years to oldest ages. In the current study we tested and validated our hypothesis by applying the above formula for appropriately ‘rescaled’ cystatin C.

Despite the growing recognition of sex-specific determinants of outcomes, representation of women in clinical studies remains low, and sex-specific management strategies are generally not provided in guidelines. We summarized the current evidence on sex-related differences in patients with CAD, focusing on the differential outcomes following medical therapy, percutaneous coronary interventions, and coronary artery bypass surgery.

MedicalResearch.com Interview with: [caption id="attachment_58481" align="alignleft" width="200"]Christopher Wallis Dr. Wallis[/caption] Christopher J. D. Wallis, MD, PhD Assistant Professor, Division of Urology University of Toronto Urologic Oncologist, Division of Urology Mount Sinai Hospital and University Health Network MedicalResearch.com: What is the background for this study? Response: Previous research has shown that female and male physicians communicate differently with patients. Further, there is evidence that female physicians, including surgeons, spend more time with patients. This, coupled with evidence that female patients may experience disparities in the management of their pain, led us to consider that communication differences may underpin differences in surgical outcomes previously noted (eg. Wallis et al, BMJ 2017) between male and female physicians. We postulated that there may be a differential association between surgeon sex and patient sex in behaviours that would translate into clinically important outcomes.

MedicalResearch.com Interview with: [caption id="attachment_57791" align="alignleft" width="120"] Anjali Sergeant[/caption] Anjali Sergeant McMaster Medicine Class of 2022 MedicalResearch.com: What is the background for this study? What are the main findings? Response: This collaborative study from the University of Toronto and McMaster University found that inpatients in the Greater Toronto Area (GTA) cared for by female physicians had lower mortality rates compared to those cared for by male physicians. Specifically, a 0.47% difference in patient deaths was reported, which is significant in the context of thousands of deaths in Ontario hospitals each year. This supports similar findings from an American study (Tsugawa et. al) published in 2017. Our study also examined gender-based differences in medical practice, including lab and imaging tests ordered, and medications prescribed. Female doctors ordered significantly more imaging tests for their patients but this factor did not explain their lower patient death rates. The mortality difference shrank when accounting for the number of years that doctors were in practice. This suggests that patients of female doctors may have better outcomes partially because more women make up newer medical grads in Canada, who may be more up-to-date on clinical guidelines.

Response: In academic internal medicine in the United States, gender disparities in salary and promotion have been researched and documented for over 20 years. Despite this, in recent years, the number of women pursuing careers in medicine has increased, and now, more women than men are enrolled in U.S. medical schools. We wanted to take a contemporary look at the composition of the U.S. academic internal medicine physician workforce and evaluate the relationships between the representation of women in each internal medicine specialty with their salaries and academic rank. We hypothesized that even though there may be more women physicians practicing in these specialties compared with prior years, the disparities in academic rank and salary, as compared with men, would still exist.

Response: The Centers for Disease Control and Prevention (CDC), the American Cancer Society (ACS), the National Cancer Institute (NCI), and the North American Association of Central Cancer Registries (NAACCR) have collaborated annually since 1998 to provide updated information about cancer occurrence and trends by cancer type, sex, age group, and racial/ethnic group in the United States. In this year’s report, we focus on national cancer statistics and highlight trends in stage-specific survival for melanoma of the skin, the first cancer for which effective immune checkpoint inhibitors were developed.

MedicalResearch.com Interview with: [caption id="attachment_57403" align="alignleft" width="150"]Darcy Banco, MD, MPH Internal Medicine Resident NYU Langone Health Dr. Banco[/caption] Darcy Banco, MD, MPH Internal Medicine Resident NYU Langone Health MedicalResearch.com: What is the background for this study? Response: We became interested in this question because of recent epidemiological data showing that despite improvements in the number of heart attacks in overall population, that number is rising among young adults (<= 55 years old) and in particular, young women. Compared to young men, young women with heart attack experience more delays in care and have higher mortality and poorer quality of life after heart attack. Despite these findings, there was also a study that asked young adults who had experienced heart attack: “When you first went for help, did the health care providers think that you were having a problem with your heart?” Women were more likely to answer no to this question. Therefore, our study asked: Are young women evaluated and treated differently than men when presenting to the emergency room with symptoms of chest pain?

Response: Gender-affirming surgeries are procedures offered to alleviate psychological distress and affirm the gender identities of transgender and gender diverse (TGD) people. Requests for these surgeries have been increasing in the United States over the past decade. However, the mental health benefits of these procedures have remained controversial due to the limited evidence base on this subject.

MedicalResearch.com Interview with: Michelle M. Chen, MD/MHS Clinical Lecturer Department of Otolaryngology-Head and Neck Surgery University of Michigan MedicalResearch.com: What is the background for this study? Response: HPV is the most common sexually transmitted infection in the United States and associated with several malignancies including oropharyngeal, cervical, vaginal, vulvar, penile, and anal cancers. In 2020, the FDA expanded the indications for HPV vaccination to include the prevention of oropharyngeal cancer, which is the most common HPV-associated malignancy and about 80% of oropharyngeal cancer patients are male. HPV vaccination rates are closely tracked for adolescents but less is known about vaccination rates for young adults. The goal of our study was to understand HPV vaccinations for young adult men and women, ages 18-21.

Response: Atherosclerotic cardiovascular disease (ASCVD), defined as ischemic heart disease (IHD), ischemic cerebrovascular disease (ICVD), or peripheral arterial disease (PAD), is the leading cause of death globally. Particularly in young ASCVD patients, secondary prevention with antiplatelet therapy and statins are extremely important in reducing disease burden.

Response: Urinary incontinence disproportionately affects women. Urinary incontinence results in significant physical, social, and psychological adverse consequences that impair women’s quality of life and contribute to considerable healthcare costs. At the moment, the contemporary prevalence and recent trends in urinary incontinence in US women are unknown. More importantly, there is a growing awareness that urinary incontinence is not part of normal aging, but very little information is available to inform prevention strategies. Therefore, we were also interested in exploring correlates of urinary incontinence in a population-based sample of US women.

Response: Financial incentives have the potential to drive provider behavior, even unintentionally. The aim of this study was to evaluate differences in clinic “productivity” measures that occur in outpatient dermatology encounters. Specifically, we used data from 2016-2020 at one academic dermatology practice to evaluate differences in work relative value units (wRVUs, a measure of clinical productivity) and financial reimbursement by patient race, sex, and age. 66,463 encounters were included in this study, among which 70.1% of encounters were for white patients, 59.6% were for females, and the mean age was 55.9 years old.
