Author Interviews, COVID -19 Coronavirus, Gender Differences, PNAS / 18.10.2020

MedicalResearch.com Interview with: Paola Profeta, PhD Professor of Public Economics, Department of Social and Political Sciences Bocconi University Director, Msc Politics and Policy Analysis, Bocconi University Coordinator, Dondena Gender Initiative, Dondena Research Center President, European Public Choice Society MedicalResearch.com: What is the background for this study? What are the main findings? Response: We interview more than 20000 men and women in 8 OECD countries in two periods during the lockdown. Using two waves from 8 OECD countries, we find that women are more likely to perceive the pandemic as a very serious health problem, to agree with restraining measures and to comply with public health rules, such as using facemasks. This gender differences are less strong for married individuals and for individuals who have been directly exposed to COVID, for instance by knowing someone who was infected.  (more…)
Author Interviews, Gender Differences, Surgical Research / 14.10.2020

MedicalResearch.com Interview with: Cassandra M. Kelleher, MD, FACS Surgical Director, Fetal Care Program Surgical Director, NICU Quality and Safety Chair, Pediatric Surgery MGH eCare Clinical Informaticist Pediatric Surgery MassGeneral Hospital for Children Boston, MA MedicalResearch.com: What is the background for this study? Response: Only about one in five surgeons practicing in U.S. is female. Unemployment is virtually nonexistent among surgeons, but many female surgeons, as well as professional women in other fields, experience underemployment—the underuse of skills—according to the Federal Reserve Bank. Women in surgery talk among themselves about how they may be perceived as less confident or competent, and for those reasons they may have less opportunity to do exciting and challenging cases. We wondered if this was true, and if so, why? (more…)
Alcohol, Author Interviews, Gender Differences, JAMA / 30.09.2020

MedicalResearch.com Interview with: Michael S. Pollard, Ph.D. Professor, Pardee RAND Graduate School Senior Sociologist RAND Corporation Santa Monica, CA 90407-2138 MedicalResearch.com: What is the background for this study? What are the main findings? Response: There are ample anecdotal jokes and stories about increased alcohol use during COVID-19 and stay-at-home orders. Our study provides robust longitudinal evidence that people drank more frequently, and for women in particular, more heavily, and with more negative consequences, during the initial stages of COVID-19 compared to their own behaviors from a year earlier (May/June 2020 compared to May/June 2019). Women’s alcohol consumption was most significantly changed, with a 17% increase in number of days drinking, and a 41% increase in days of binge drinking (when they had four or more drinks in a couple of hours). This means that, nationally, one in five women drank heavily one more day a month than the same time in 2019, on average. Women also reported a 39% increase in alcohol-related problems, such as “I took foolish risks” or “I failed to do what was expected of me” because of drinking alcohol. (more…)
Author Interviews, Gender Differences, JAMA, Pain Research / 29.09.2020

MedicalResearch.com Interview with: Jason Nagata, MD, MSc Assistant Professor of Pediatrics University of California, San Francisco San Francisco, California  MedicalResearch.com: What is the background for this study? Response: Although prior research has identified disparities in migraine by race and sex, little was previously known about disparities in migraine by sexual orientation.  MedicalResearch.com: What are the main findings?  Response: In a national sample of nearly 10,000 adults in the USA, we found that nearly one third of lesbian, gay, and bisexual individuals have experienced a migraine. Overall, we found that lesbian, gay, or bisexual individuals had 58% higher odds of experiencing a migraine compared to heterosexual individuals. We also found that individuals who identified as mostly heterosexual but with some same-sex attractions were more likely to experience a migraine compared to those who identified as exclusively heterosexual.

Author Interviews, Gender Differences, Hepatitis - Liver Disease, Infections / 10.07.2020

MedicalResearch.com Interview with: Sabrina Annick Assoumou, MD, MPH Assistant Professor, Medicine Infectious Diseases at Boston Medical Center Boston University School of Medicine MedicalResearch.com: What is the background for this study? Response: During the opioid epidemic there has been an increase in the number of hepatitis C virus (HCV) infections due to transmission among persons who inject drugs (PWID). Federally qualified health centers (FQHC) provide care to an underserved and diverse patient population with a high proportion of both injection drug use and HCV. These health care facilities could provide opportunities to enhance HCV testing and treatment, especially at a time when recent data show that the United States is not on the list of high-income nations expected to achieve the World Health Organization’s goal of eliminating HCV by 2030.

Author Interviews, CDC, Diabetes, Gender Differences, Race/Ethnic Diversity / 29.06.2020

MedicalResearch.com Interview with: Giuseppina Imperatore, MD, PHD CDC, Atlanta MedicalResearch.com: What is the background for this study? Response: The lifetime risk of diabetes (LRD), a probability of developing diabetes during a person’s lifespan, is a measure of future disease burden that reflects the impact of incidence (occurrence of new cases per year) and mortality. The years of potential life lost to diabetes (YPLLD) is the number of life-years lost due to diabetes, calculated as the difference between the life expectancy of a person without diabetes and a person with diabetes at the age of diagnosis. For example, the number of life-years lost for a person diagnosed at age 20 years is the difference in life expectancy of a person who died without developing diabetes and a person who was diagnosed with diabetes at 20 years of age.  Both incidence and mortality of diabetes have been decreasing for more than a decade. The effects of those changes on lifetime risk of diabetes and years of potential life lost to diabetes are not known. In this study, we used nationally representative diabetes surveillance data to provide updated estimates for the lifetime probability of development of diabetes, and to assess changes in incidence and mortality on lifetime risk and life-years lost due to diabetes in the USA.

Author Interviews, Cannabis, Gender Differences / 21.05.2020

MedicalResearch.com Interview with: Francesca Filbey, PhD Associate Provost and Professor of Cognition and Neuroscience Bert Moore Chair The University of Texas at Dallas MedicalResearch.com: What is the background for this study? Response:  Studies have reported differences in how males and females respond to cannabis and how they develop problems related to cannabis use.  We sought to determine whether craving may underlie this difference in male and female cannabis users. (more…)
Author Interviews, Gender Differences, JAMA, Surgical Research, University of Pittsburgh / 21.05.2020

MedicalResearch.com Interview with: Sara P. Myers, M.D., Ph.D. University of Pittsburgh School of Medicine  MedicalResearch.com: What is the background for this study? Response: Compared to other fields, medicine, and especially academic surgery and its subspecialties, trail with respect to gender diversity. Considering that these fields were traditionally male-dominated, two issues that may present ongoing challenges to the retention and promotion of women are pro-male bias and negative stereotypes about women. Training specific to pursuing a surgical career begins in residency, so it is important to understand how these issues affect motivation and achievement during this formative period. In our study we first evaluated the association between pro-male bias and research-related career engagement using a survey methodology, and then looked at whether evoking negative stereotypes about women was associated with reduced performance on a simulated technical skill assessment called the Fundamentals of Laparoscopic Surgery (FLS) assessment.  (more…)
Author Interviews, Brigham & Women's - Harvard, Gender Differences, Genetic Research, Nature / 13.05.2020

MedicalResearch.com Interview with: Nolan Kamitaki PhD Harvard Medical School MedicalResearch.com: What is the background for this study? Response: Previous work from our lab found that the strongest common genetic association to schizophrenia is driven in part by copy number variation of the C4 genes.  Given that lupus and Sjogren's syndrome, two autoimmune disorders, have association patterns that span the same region of the human genome, we wondered if part of the signal for these diseases may also arise from variation of C4 given that both have hypocomplementemia as a characterizing trait.   The other main finding is that these associations appear to be sex-biased, where the protection from each additional copy of the C4 gene was greater in men than in women.  When we went back to the data used in the previous study from our lab association C4 variation to schizophrenia, we found that the effect was stronger in men there as well.  Although the expression of C4 at the RNA level does not appear to differ between men and women, we saw that men had more C4 protein in both cerebrospinal fluid and blood plasma, suggesting that this may explain the greater genetic association in men.

Author Interviews, Gender Differences, Heart Disease, Karolinski Institute, Opiods, PNAS / 18.03.2020

MedicalResearch.com Interview with: Mikko Myrskylä PhD Executive Director, Max Planck Institute for Demographic Research Professorial Research Fellow, London School of Economics Professor of Social Statistics University of Helsinki MedicalResearch.com: What is the background for this study? Response: Life expectancy in the U.S. increased at a phenomenal pace throughout the twentieth century, by nearly two years per decade. After 2010, however, U.S. life expectancy growth stalled and has most recently been declining. A critical question for American health policy is how to return U.S. life expectancy to its pre-2010 growth rate. Researchers and policy makers have focused on rising drug-related deaths in their search for the explanations for the stalling and declining life expectancy. (more…)
Author Interviews, Education, Gender Differences, JAMA, Race/Ethnic Diversity, Yale / 24.02.2020

MedicalResearch.com Interview with: Katherine A. Hill, BA, BS Yale School of Medicine New Haven, Connecticut MedicalResearch.com: What is the background for this study? Response: Previous studies have shown that mistreatment is a common and damaging experience for medical students. However, there is little research on whether the prevalence of medical student mistreatment varies by demographic factors such as student sex, race/ethnicity, and sexual orientation.  (more…)
Author Interviews, Endocrinology, Gender Differences, Genetic Research, Science / 22.02.2020

MedicalResearch.com Interview with: Lawrence C. Layman, M.D. Robert B. Greenblatt, M.D., Distinguished Chair in Endocrinology Professor & Chief Section of Reproductive Endocrinology, Infertility, & Genetics Department of Obstetrics & Gynecology Director, REI Fellowship Program Co-Director, MD/PhD Program Department of Neuroscience & Regenerative Medicine Department of Physiology Medical College of Georgia at Augusta University MedicalResearch.com: What is the background for this study? Response: I have taken care of many transgender patients over the past 20 years. We think there is a biological basis for transgender identity rather than choice. Animal models suggest that exposure to estrogen or testosterone at a critical time during development will render an animal of either sex to behave as male with aggressive behavior and they will mount females. If this pathway is blocked, then the end result is more receptive, female sexual behavior. We thought that variants in genes involved in metabolizing these hormones in the brain could play some role in transgender identity. Because the cost of sequencing all genes was similar to the cost of looking for changes in just these genes, we performed whole exome sequencing (sequencing the protein coding regions of genes) on about 30 transgender patients.

Author Interviews, Education, Gender Differences, Neurology, UC Davis / 27.01.2020

MedicalResearch.com Interview with: Allison Brashear, M.D., M.B.A. Dean, UC Davis School of Medicine MedicalResearch.com: What is the background for this study? Why is the demand for neurology services and neurologists increasing?  Response: The American Academy of Neurology estimates that by 2025 the number of neurologists in practice will increase to 18,060 but some 3,400 more will be needed to meet the demand for their services. The 58% increase in the number of residency positions in the National Resident Matching Program since 2008 also reflects the growing demand. The higher prevalence of neurologic conditions, aging U.S. population and more patients having access to the health care coverage are the major driving forces. (Note: source of NRMP neurology trend data comes from a physician/resident forum posted May 2019 https://forums.studentdoctor.net/threads/growth-trends-in-neurology-residency-positions.1375918/) MedicalResearch.com: Why is neurology included among the less desirable fields of medicine (similar to nephrology, infectious disease, endocrinology etc.) for medical students and residents to pursue?  Why is burnout and dissatisfaction so high? Response: According to the American Academy of Neurology, a minority of medical students choose to train in neurology each year, with approximately 3.1% matching into a neurology residency in 2018. The newer generations of neurologists value lifestyle and time off work more than their predecessors. According to a recent American Medical Association survey, neurology tied with critical care as the medical specialty with the highest stress levels and burnout. Too many administrative tasks, too many hours at work, increased computerization of practice and insufficient compensation were among the top causes of burnout. (more…)
Author Interviews, Cancer Research, Gender Differences, Genetic Research / 21.01.2020

MedicalResearch.com Interview with: Alejandro Cáceres PhD Juan R. González, PhD Barcelona Institute for Global Health (ISGlobal) Barcelona, Spain. MedicalResearch.com: What is the background for this study? What are the main findings? Response: Men have more risk and worse prognosis to cancer than women. There are many environmental factors but also biological differences. We find that the loss of function of six genes (DDX3Y, EIF1AY, KDM5D, RPS4Y1, UTY and ZFY) in chromosome Y is one of the biological factors for the differences between sexes in relation to cancer risk and prognosis.  (more…)
Author Interviews, Dermatology, Education, Gender Differences, JAMA, Race/Ethnic Diversity / 08.01.2020

MedicalResearch.com Interview with: Imam Xierali, PhD Associate Professor / UT Southwestern Medical Center Dallas, Texas MedicalResearch.com: What is the background for this study? Response: Despite the continued efforts in academic medicine to increase the representation of women and minorities underrepresented in medicine (URM), there is a lack of information on trends in dermatology department faculty diversity and how they compare with those in other clinical departments. (more…)
Author Interviews, Gender Differences, JAMA, Occupational Health, Surgical Research / 05.01.2020

MedicalResearch.com Interview with: Matilda Anderson MBBS MBS General Surgery Trainee/Public Health/Researcher Footscray, Victoria, Australia MedicalResearch.com: What is the background for this study? Response: Female representation in the surgical workforce is increasing.  Previous studies have shown higher infertility rates and adverse pregnancy outcomes in this population.  We aimed to accurately define the available research in this area and provide some basic recommendations about how workplaces can support their female surgical residents and surgeons. On a more personal note- Dr Anderson is a female surgical resident and have seen countless pregnant colleagues remove themselves from operating rooms with the concern about how the conditions may affect their pregnancies.  Dr. Anderson met Associate Professor Goldman at Harvard University (a leading expert on occupational reproductive hazards) and collaborated to explore this area further.

Author Interviews, Gender Differences, OBGYNE / 03.12.2019

MedicalResearch.com Interview with: Dr. Amanda N. Sferruzzi-Perri University Lecturer in Physiology Royal Society Dorothy Hodgkin Research Fellow & Lister Institute Fellow University of Cambridge MedicalResearch.com: What is the background for this study? Response: Having a pregnancy in advanced age (35 years or older) is often associated with a series of risks and complications for both the mother and her baby. These include preeclampsia (raised blood pressure in the mother during pregnancy), gestational diabetes (diabetes in the mother that develops onset in pregnancy), stillbirth and fetal growth restriction. There is also evidence from work in experimental animals that offspring from mothers who have entered pregnancy at an older age, are at heightened risk of heart problems and high blood pressure as young adults and particularly so, if they are male rather than female. We wondered whether these sex-related differences may derive from the way in which the male and female fetuses were supported within the womb, in an aged mother during pregnancy. (more…)
AHA Journals, Author Interviews, Gender Differences, Stroke / 30.11.2019

MedicalResearch.com Interview with: Cheryl Carcel MD Research Fellow, Stroke & Women's Health Program Conjoint Senior Lecturer, Faculty of Medicine, UNSW Sydney Associate Lecturer, Sydney Medical School, The University of Sydney The George Institute for Global Health | Australia MedicalResearch.com: What is the background for this study? Response: This study builds on previous findings of differences in the presentation, treatment and outcome for women and men who experience stroke. For this analysis, we pooled five large international, multicenter, randomized controlled trials that included the following: the Intensive Blood Pressure Reduction in Acute Cerebral Hemorrhage Trials (INTERACT-1 and -2 studies), the alteplase-dose arm of the Enhanced Control of Hypertension and Thrombolysis Stroke study (ENCHANTED), the Head Position in Acute Stroke Trial (HeadPoST), and the Scandinavian Candesartan Acute Stroke Trial (SCAST).

Author Interviews, Dermatology, Gender Differences, Pediatrics / 17.11.2019

MedicalResearch.com Interview with: Markus Boos, MD, PhD Member of the Society for Pediatric Dermatology. Attending pediatric dermatologist Seattle Children's Hospital Assistant Professor in the Department of Pediatrics University of Washington School of Medicine  MedicalResearch.com: What is the background for this study? Response: Our understanding of the cutaneous health of sexual and gender minority (SGM) individuals (lesbian, gay, bisexual, transgender, queer, asexual, intersex, nonbinary, etc.) remains nascent. This dearth of understanding of the unique needs of SGM children is even more pronounced. This 2-part review article provides practical advice on how to best engage with young SGM patients and serve the distinct needs of this minority population, with a specific emphasis on dermatologic conditions.

Author Interviews, Education, Gender Differences, JAMA / 13.11.2019

MedicalResearch.com Interview with: Shannon Ruzycki, MD, MPH, FRCPC, (she/hers) General Internist & Clinical Lecturer Department of Medicine Department of Community Health Sciences Cumming School of Medicine University of Calgary MedicalResearch.com: What is the background for this study? Response: After hearing about the National Academies of Science, Engineering, and Medicine 2018 report to congress on sexual harassment of women in academia, our Department Head asked myself and Dr. Aleem Bharwani to study experiences of gender inequity or equity in our Department. We conducted an in-depth, 18-month mixed methods study of women and men in our Department, including semi-structured interviews and survey. (more…)
Author Interviews, Cancer Research, Gender Differences, JAMA / 02.11.2019

MedicalResearch.com Interview with: Nina Niu Sanford, M.D. Assistant Professor Dedman Family Scholar in Clinical Care UT Southwestern Department of Radiation Oncology Dallas TX MedicalResearch.com: What is the background for this study? Response: Minority racial/ethnic groups present at later stages of cancer and have worse stage-specific survival rates.  Cultural competency represents a single element within the dynamic and trans-disciplinary field of health disparities, but is an important modifiable factor for both providers and health organizations that could be associated with disparities in cancer outcomes. There have been longstanding initiatives and training requirements in medical education specifically designed to improve provider cultural competency over the past couple of decades, and the American Society of Clinical Oncology (ASCO) has recently outlined goals for improving cultural competency within its policy statement on cancer disparities. Moreover, ASCO health disparity policies have recently highlighted the association between racial/ethnic disparities in cancer outcomes and a “lack of access to high-quality care that is understanding and respectful of diverse traditions and cultures plays a significant role.”  Given the above, we wished to assess access to culturally competent providers among patients with cancer by race/ethnicity. (more…)
Author Interviews, Gender Differences, HPV / 16.09.2019

MedicalResearch.com Interview with: Dr. Ashish A. Deshmukh UT Health School of Public Health Houston MedicalResearch.com: What is the background for this study? Response: The HPV vaccination is recommended for females and males for prevention of 6 cancers (cervical, oropharyngeal, anal, penile, vaginal, and vulvar). Nearly 43,000 HPV-associated cancer cases are diagnosed every year in the US. Yet, it is extremely unfortunate and something that continues to bother us that HPV vaccination coverage remains low (50% in 2018) in the US and completion rate is nearly 5% lower in boys. Different from some industrialized nations where vaccination policy is school-based, vaccination policy in the US is clinic-based and parents are generally responsible for making vaccination decisions for their children. Generally, there are two main factors that drive parents’ decision-making: (1) how much knowledge they have of HPV and (2) recommendation from a healthcare professional. We analyzed the National Cancer Institute’s Health Information National Trend Survey (HINTS) of over 6000 participants focusing on their knowledge of HPV and HPV vaccination and whether participants received any vaccination recommendation from their health care provider.  (more…)
Author Interviews, Cannabis, Columbia, Gender Differences / 06.09.2019

MedicalResearch.com Interview with: Morgan Philbin, PhD MHS Assistant Professor Department of Sociomedical Sciences Columbia University School of Public Health MedicalResearch.com: What is the background for this study? Response: Marijuana is the most frequently used substance in the United States (US) after alcohol and tobacco. In 2017, 15.3% of the US population ages 18 and up reported past-year marijuana use (MU) and 9.9% past month use. Individuals who identify as lesbian, gay, or bisexual (LGB), also report higher levels of marijuana use and marijuana use disorder than their heterosexual counterparts. Researchers have begun to explore potentially modifiable factors, such as state-level marijuana policies, that affect marijuana use and related outcomes at the population-level and within subgroups—though as of yet not among sexual minority populations. We therefore examined whether LGB individuals living in states with medical marijuana laws (MMLs) have higher levels of marijuana use and marijuana use disorder compared to LGB individuals in states without MMLs.

Author Interviews, Cognitive Issues, End of Life Care, Gender Differences, JAMA / 16.08.2019

MedicalResearch.com Interview with: Dr. Nathan Stall, MD Geriatrician and Research fellow Women’s College Research Institute       Dr. Paula Rochon, MD, MPH, FRCPC Periatrician and Vice-President of Research Women’s College Hospital     MedicalResearch.com: What is the background for this study? Response: The advanced stages of the dementia are characterized by profound memory impairment, an inability to recognize family, minimal verbal communication, loss of ambulatory abilities, and an inability to perform basic activities of daily living. Nursing homes become a common site of care for people living with advanced dementia, who have a median survival of 1.3 years. In the advanced stages of the disease, the focus of care should generally be on maximizing quality of life. Our study examined the frequency and sex-based differences in burdensome interventions received by nursing home residents with advanced dementia at the very end of life. Burdensome interventions include a variety of treatment and procedures that are often avoidable, may not improve comfort, and are frequently distressing to residents and their families. We found that in the last 30 days of life, nearly one in 10 nursing home residents visited an emergency department, more than one in five were hospitalized, and one in seven died in an acute care setting. In addition, almost one in 10 residents received life-threatening critical care; more than one in four were physically restrained; and more than one in three received antibiotics. (more…)
Author Interviews, Gender Differences / 16.08.2019

MedicalResearch.com Interview with: Jack Turban MD MHS Resident Physician in Psychiatry The Massachusetts General Hospital and McLean Hospital Harvard Medical School MedicalResearch.com: What is the background for this study? Response: Gender identity conversion efforts are attempts by a professional (for example a therapist, counselor, or religious advisor) to make a transgender person cisgender. The practice has been labelled unethical and ineffective by major medical organizations, including the American Medical Association. Accordingly, many U.S. states have made this practice illegal. Other states, however, have deferred passing bans on gender identity conversion efforts. Some state legislators have argued that such bans are unnecessary because this practice doesn’t occur in their state. (more…)
Author Interviews, Education, Gender Differences, JAMA, Surgical Research / 07.08.2019

MedicalResearch.com Interview with: Maria S. Altieri, MD, MS Invasive Surgery Stony Brook, NY MedicalResearch.com: What is the background for this study? What are the main findings? Response: For majority of residents, training years coincide with prime child bearing years.  Historically, surgical residency has not been conducive for having children, as it is one of the most demanding experiences, requiring long hours, high stress levels, and the acquisition of clinical and technical skills over a short period of time. However, with recent trends towards a more favorable work-life balance and the 80-hour work week, more male and female residents are having children or considering having children during training.  Thus, the topic of parental leave during residency is becoming more fundamental.  However, there is little research on the attitudes of residents towards their pregnant peers and parental leave. We wanted to examine the perceptions of surgical trainees towards parental leave and pregnancy during residency.  Through understanding the perceptions of current residents, obstacles could be identified which could lead to potential changes in policies that could help to normalize parenthood and parental leave during surgical training.    (more…)
BMJ, Gender Differences / 25.07.2019

MedicalResearch.com Interview with: Dr Crystal Lee BMedSc(Hons), MIPH, PhD, MBiostat Senior Research Fellow School of Psychology and Public Health La Trobe University Honorary Research Fellow The Boden Institute of Obesity, Nutrition, Exercise & Eating Disorders The University of Sydney Adjunct Senior Research Fellow School of Public Health | Curtin University  MedicalResearch.com: What is the background for this study? Response:  Coronary heart disease (CHD) is a leading cause of death and disability worldwide. Primary care has been shown to play an important role in the secondary prevention of cardiovascular disease. Yet, studies in Australia and elsewhere from as far back as two decades ago identified gaps in the management of CHD patients in primary care. We analysed records of 130,926 patients with a history of CHD from 438 general practices across Australia to determine whether sex disparities exist in the management of CHD according to current clinical guidelines.

Aging, Author Interviews, Cognitive Issues, Gender Differences, Hormone Therapy, JAMA, Menopause, Weight Research / 05.07.2019

MedicalResearch.com Interview with: Rachel Zsido PhD student Department of Neurology International Max Planck MedicalResearch.com: What is the background for this study? Response: We integrated measures of brain network structure, visceral adipose tissue (VAT), serum estradiol levels, and cognitive performance from 974 participants in order to shed light on potential mechanisms underlying cognitive health. We believe it is imperative to assess sex-specific risk trajectories in brain aging and cognitive decline, especially given the known sex differences in both VAT accumulation patterns and estradiol fluctuations across the lifespan. Thus, we aimed to answer three questions in men and in women: 1) Does visceral adipose tissue exacerbate the association between age and brain network structure, 2) Does estradiol mitigate the negative association between VAT and brain network structure, and 3) What does this imply for healthy cognitive aging in men and women?  (more…)
Author Interviews, Gender Differences, Sleep Disorders / 16.06.2019

MedicalResearch.com Interview with: Ambra Stefani, MD Sleep Disorders Clinic Department of Neurology Innsbruck Medical University Innsbruck, Austria  MedicalResearch.com: What is the background for this study? Response: Restless legs syndrome (RLS) is a common neurological disorder, affecting up to 10% of the general population in Europe and North America. It is a sensorimotor disorder characterized by unpleasant sensations and an urge to move, mainly involving the legs. These symptoms appear or worsen in the evening/at night and improve with movement. Background for this study was the idea that there might be gender differences in the phenotypical presentation of RLS, as the pathogenesis of this disease is multifactorial and gender specific factors also play a role. (more…)
