Author Interviews, Brigham & Women's - Harvard, Cancer Research, Dermatology / 03.09.2020

MedicalResearch.com Interview with: Yin Zhang MD Research Fellow in Medicine Brigham and Women's Hospital and Harvard Medical School MedicalResearch.com: What is the background for this study? Response: Among modern hair dyes, permanent hair dye is the most popular type, and is the most aggressive and extensively used type that has posed the greatest potential concern about cancer risk. Monitoring and investigating the carcinogenic hazard to people from personal use of permanent hair dyes has major public health implications. In 2008, the World Health Organization's International Agency for Research on Cancer, after comprehensive reviewed prior evidence, classified occupational exposure to hair dyes as a probable carcinogen to humans (group 2A), whereas personal use of hair dyes was not classifiable as to its carcinogenicity to humans (Group 3). Data on hair dye safety has also been continuously monitored by the USFDA. Prior epidemiological evidence may have been influenced by not discriminating between personal and occupational exposure, an inability to distinguish types and colors of hair dyes used, imprecise assessment of several critical domains of exposure history (duration, frequency and cumulative dose), and inadequate control for potential confounding.

Accidents & Violence, Author Interviews, Brigham & Women's - Harvard, Emergency Care, JAMA, Surgical Research / 01.09.2020

MedicalResearch.com Interview with: Sarabeth Spitzer, MD Co-Chair of Board, Scrubs Addressing the Firearm Epidemic (SAFE) Department of Surgery, Brigham and Women’s Hospital MedicalResearch.com: What is the background for this study? What are the main findings? Response: Firearm injury is a significant cause of morbidity and mortality in the United States, resulting in almost 40,000 deaths annually in the United States, but very little is known about the epidemiology of nonfatal firearm injuries. Nonfatal firearm injuries can have significant long-term morbidity and are associated with significant cost. We found that there were over 81,000 nonfatal firearm injuries in California over the study period. Over the period, there was a decrease in nonfatal firearm injuries by 38.1%, driven primarily by a decrease in assault injuries.   (more…)
Author Interviews, Brigham & Women's - Harvard, Gastrointestinal Disease, Technology / 27.08.2020

MedicalResearch.com Interview with: Giovanni Traverso, MB, BChir, PhD Gastroenterologist and biomedical engineer Division of Gastroenterology at BWH Instructor of medicine at Harvard Medical School MedicalResearch.com: What is the background for this study? Response: We began working on this project with the goal to develop liquid drug formulations that could offer an easier-to-swallow alternative to capsules, especially for children. We started to think about whether we could develop liquid formulations that could form a synthetic epithelial lining that could then be used for drug delivery, making it easier for the patient to receive the medication by providing drugs in extended release formats. We discovered that an enzyme called catalase could help assemble molecules of dopamine into the polymer (poly-dopamine). These polymers have muco-adhesion properties, which means that after polymerization, the polymer can attach to the tissue very strongly. Also, catalase is found throughout the digestive tract, with especially high levels in the upper region of the small intestine. This is the first example, to the best of our knowledge, of small intestinal targeting system enabled through in-situ tissue-enzyme-catalyzed polymerization. The coating lasts up to 24 hours, after which it is shed and excreted based on experiments we conducted in pigs. (more…)
Author Interviews, Brigham & Women's - Harvard, COVID -19 Coronavirus, JAMA, Social Issues / 21.08.2020

MedicalResearch.com Interview with: Monik Carmen Jimenez, Sc.D Assistant Professor of Medicine Brigham and Women's Hospital MedicalResearch.com: What is the background for this study? Response: We wanted to get a comprehensive picture of the epidemiology of COVID-19 in carceral facilities that included jails and was not restricted solely to prisons. We utilized publicly available data collected in Massachusetts, pursuant to a court order. These data included prison and jail systems and were used to calculate rates of confirmed cases of COVID-19 and testing rates among incarcerated individuals. We were also able to compare those to changes in the population size within each system. (more…)
Author Interviews, Brigham & Women's - Harvard, Cancer Research, Dermatology, JAMA / 14.08.2020

MedicalResearch.com Interview with: Maryam M. Asgari, MD MPH Professor Department of Dermatology, Massachusetts General Hospital Department of Population Medicine, Harvard Medical School MedicalResearch.com: What is the background for this study? What are Topical Calcineurin Inhibitors used for?  Response: Topical calcineurin inhibitors (TCIs) are FDA approved for the treatment of atopic dermatitis (though they are used off-label to treat a wide range of inflammatory conditions of the skin, including psoriasis, seborrheic dermatitis, and contact dermatitis).  There are currently two drugs available – tacrolimus and pimecrolimus – both of which carry a black box label warning users about the potential for increased skin cancer risk.  The risk associated with keratinocyte carcinoma, the most common cancer (defined as basal cell carcinoma and squamous cell carcinoma), remains poorly defined because findings from large-scale post-marketing surveillance studies are lacking.  (more…)
Author Interviews, Brigham & Women's - Harvard, Exercise - Fitness, Race/Ethnic Diversity, Social Issues / 03.08.2020

MedicalResearch.com Interview with: Marc Weisskopf, PhD, ScD Cecil K. and Philip Drinker Professor of Environmental Epidemiology and Physiology Departments of Environmental Health and Epidemiology Harvard T.H. Chan School of Public Health Boston, MA 02115  MedicalResearch.com: What is the background for this study? Response: There is a long history of health disparities by race. We were interested to see whether these also show up in professional football players, with the thought that perhaps the advantages that come with being an elite athlete in a sport (e.g. related to income, potential access to carte, prestige) might minimize health disparities.

Author Interviews, Brigham & Women's - Harvard, Cost of Health Care, Heart Disease, JAMA / 28.07.2020

MedicalResearch.com Interview with: Frank Wharam, MD, MPH Department of Population Medicine Harvard Medical School and Harvard Pilgrim Healthcare Institute Boston, MA 02215 MedicalResearch.com: What is the background for this study? Response:  There is substantial concern that high-deductible health plans increase people’s risk of major adverse health events such as heart attack and stroke. No studies have examined this question. This study examines the effects of a transition to a high-deductible health plan on the risk of major adverse cardiovascular outcomes (myocardial infarction and stroke). The study group included individuals with risk factors for cardiovascular disease who were continuously enrolled in low-deductible (<$500) health plans during a baseline year followed by up to 4 years in high-deductible (≥$1000) plans after an employer-mandated switch. The matched control group included individuals with the same risk factors who were contemporaneously enrolled in low-deductible plans.  We examined time to first major adverse cardiovascular event, defined as myocardial infarction or stroke.  (more…)

MedicalResearch.com Interview with: Daniel Hal Solomon, MD, MPH Associate Physician, Brigham and Women's Hospital Professor of Medicine, Harvard Medical School Brigham and Women's Hospital Department of Medicine Rheumatology, Immunology Boston, MA 02115 Editor’s note: Prolia® is the trade name for denosumab.  MedicalResearch.com: What is the background for this study? Response: We conducted this study to assess whether delays in denosumab (injections were associated with an increased risk of fractures. In a prior study, we found that the improvements in bone mineral density were reduced among patients who delayed injections. (more…)
Author Interviews, Brigham & Women's - Harvard, Cancer Research, Dental Research, Esophageal, Gastrointestinal Disease / 24.07.2020

MedicalResearch.com Interview with: Mingyang Song, MD, ScD. Division of Gastroenterology Clinical and Translational Epidemiology Unit, Massachusetts General Hospital and Harvard Medical School Department of Nutrition and Department of Epidemiology Harvard T.H. Chan School of Public Health Boston, Massachusetts MedicalResearch.com: What is the background for this study? Response: Recent studies showed a presence of dysbiotic oral microbiome in patients with esophageal and gastric cancer, suggesting a link between oral health and these cancers. However, how periodontal disease and tooth loss may influence the risk of these cancers has been inconsistent.  MedicalResearch.com: What are the main findings? Response: Our findings support a possible role of oral health in the development of upper GI cancer. Individuals with periodontal disease and tooth loss are at higher risk of developing esophageal and gastric adenocarcinoma. The risk is particularly high for individuals with both periodontal disease and tooth loss.  (more…)
Author Interviews, Brigham & Women's - Harvard, Geriatrics, Lipids / 08.07.2020

MedicalResearch.com Interview with: Ariela Orkaby, MD, MPH Geriatrics & Preventive Cardiology Associate Epidemiologist Division of Aging, Brigham and Women's Hospital Assistant Professor of Medicine, Harvard Medical School MedicalResearch.com: What is the background for this study? Response: Statins are cholesterol lowering medications that have been proven to prevent heart attacks, strokes and death in middle-aged adults. Current guidelines for cholesterol lowering therapy are uncertain as to treatment for older adults due to a lack of available data, even though older adults are at the highest risk of heart disease and death.

Author Interviews, Brigham & Women's - Harvard, Cognitive Issues, Sleep Disorders / 01.07.2020

MedicalResearch.com Interview with: Dr. Rebecca Robbins, PhD MS Fellow at Brigham & Women's Hospital and Harvard Medical School MedicalResearch.com: What is the background for this study? Response: Sleep difficulties are common among older adults and are associated with cognitive decline. We used data collected over 10 years from a large, nationally representative longitudinal survey of adults over the age of 50 in the U.S. We examined the relationship between specific sleep difficulties and cognitive function over time. MedicalResearch.com: What are the main findings?  Response: Our results show that early difficulty falling asleep and early morning awakenings, when experienced "most nights" of the week, were each associated with worse cognitive function. Conversely, reports of waking feeling rested was associated with better cognitive function, over time.   (more…)
Author Interviews, Brigham & Women's - Harvard, Critical Care - Intensive Care - ICUs, NEJM, Pediatrics / 24.06.2020

MedicalResearch.com Interview with: Christopher P. Landrigan, MD, MPH Chief, Division of General Pediatrics, Boston Children’s Hospital Director, Sleep and Patient Safety Program, Brigham and Women's Hospital William Berenberg Professor of Pediatrics, Harvard Medical School Boston Children's Hospital Boston, MA 02115 MedicalResearch.com: What is the background for this study? Response: An enormous body of literature demonstrates that sleep deprivation adversely affects the safety and performance of resident physicians, as well as individuals across other occupations.  Resident physicians are at greatly increased risk of suffering motor vehicle crashes and needlestick injuries, and are at substantially increased risk of making medical errors, when working on traditional schedules that include 24-hour shifts. We previously conducted a randomized controlled trial in two intensive care units that found resident physicians made 36% fewer medical errors when a scheduling intervention was introduced that eliminated 24-hour shifts but held resident workload constant. The current study, ROSTERS, was a 6-center study that again introduced a scheduling intervention to eliminate 24-hour shifts in intensive care units.  Due to varying resources and unit organization across sites, each hospital developed its own staffing plan to accommodate the intervention​.

Author Interviews, Brigham & Women's - Harvard, Cognitive Issues, Heart Disease, JACC, Lipids / 23.05.2020

MedicalResearch.com Interview with: Robert P. Giugliano, MD, SM Senior Investigator, TIMI Study Group Cardiovascular Medicine Brigham and Women's Hospital Professor of Medicine Harvard Medical School Boston, MA  MedicalResearch.com: What is the background for this study? Response: Some prior studies had suggested that lipid lowering therapies were associated with impaired cognition.  We sought to explore this question in a prospectively designed substudy of the large FOURIER randomized, double-blind clinical trial utilizing patient self-surveys administered the end of the study to determine whether patients themselves noticed any changes in cognition over the duration of the trial. The survey tool was a shortened version of the Everyday Cognition Questionnaire (see attached) that asks patients 23 questions that assess memory and executive function (including subdomains of planning, organization, and divided attention). The questions are in the format of "Compared to the beginning of the study, has there been any change in .....", and are graded as 1=better/no change, 2=questionable/occasionally worse, 3=consistently a little worse, 4=consistently much worse.

Author Interviews, Brigham & Women's - Harvard, Cost of Health Care, Heart Disease, Race/Ethnic Diversity, Statins / 14.05.2020

MedicalResearch.com Interview with: Dr. Ankur Pandya, PhD Assistant Professor of Health Decision Science Department of Health Policy and Management Harvard T.H. Chan School of Public Health MedicalResearch.com: What is the background for this study? Response: The 2013 ACC-AHA cholesterol treatment guidelines greatly expanded statin medication eligibility for individuals between the ages of 40-75 years without known cardiovascular disease, and there was some concern that African Americans at "intermediate risk" per those guidelines could be (arguably) overtreated with statins. The 2018 ACC-AHA guidelines included coronary artery calcium assessment for individuals at intermediate cardiovascular disease risk; those with a "zero" calcium score and no other risk factors would now change the eligibility (from indicated statin to not indicated). (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, Brigham & Women's - Harvard, Nature, Weight Research / 05.05.2020

MedicalResearch.com Interview with: Ronald Kahn, MD Chief Academic Officer, Joslin Diabetes Center Mary K. Iacocca Professor of Medicine Harvard Medical School MedicalResearch.com: What is the background for this study? What are the main findings? Response: Adipose tissue is a heterogeneous organ and composed of several cell types, including mature adipocytes, preadipocytes, stem cells, endothelial cells, and various blood cells. Different adipose depots have distinct physiological functions associated with their anatomical location and cell composition. For example, accumulation of intra-abdominal (visceral) white adipose tissue is associated with insulin resistance and metabolic syndrome, whereas accumulation of subcutaneous adipose tissue is not metabolically detrimental and may be even associated with increased insulin sensitivity. Determining the mechanisms for these phenotypic differences could lead to development of novel therapies for diabetes, obesity, and their associated morbidities. A central challenging question in research of metabolic disease is whether disease risk for diabetes and metabolic syndrome is driven by a subset of fat cells that may interact with environmental stresses in disease pathogenesis in a way different from other fat cells. Indeed, previous studies from the Kahn lab have shown different fat cells in a single depot from the mouse may exhibit developmental heterogeneity. In this new study, we attempted to address this question for human white fat using a synergistic application of several methodologies: 1) single cell transcriptional profiling of human white fat during differentiation, 2) analysis of individual clones of white fat cells taken from humans at surgery, 3) novel computer based network analysis and 4) integration of the gene signatures across experimental models. Single-cell RNA sequencing is an ideal technique to profile gene expression of heterogeneous cell populations obtained from a single tissue, including fat tissue. (more…)
Author Interviews, Beth Israel Deaconess, Brigham & Women's - Harvard, Cost of Health Care, Geriatrics, JAMA, Medicare / 12.03.2020

MedicalResearch.com Interview with: Rishi K. Wadhera, MD Harvard Medical Faculty Physicians Cardiovasular Diseases Beth Israel Deaconess Medical Center  MedicalResearch.com: What is the background for this study? Response: In the U.S., income inequality has steadily increased over the last several decades. Given widening inequities, there has been significant concern about the health outcomes of older Americans who experience poverty, particularly because prior studies have shown a strong link between socioeconomic status and health. In this study, we evaluated how health outcomes for low-income older adults who are dually enrolled in both Medicare and Medicaid have changed since the early 2000’s, and whether disparities have narrowed or widened over time compared with more affluent older adults who are solely enrolled in Medicare (non-dually enrolled).

Alcohol, Author Interviews, Brigham & Women's - Harvard / 11.03.2020

MedicalResearch.com Interview with: John F. Kelly, Ph.D., ABPP. Recovery Research Institute Elizabeth R. Spallin Professor of Psychiatry in Addiction Medicine Harvard Medical School   MedicalResearch.com: What is the background for this study? Response: Alcohol use disorder is one of the leading causes of disease, disability, and preventable death worldwide. Alcoholics Anonymous (AA) is a widespread international recovery support organization designed to address it. While it has remained popular and influential for many decades, until recently the quantity and quality of the research on AA and clinical treatments designed to stimulate AA involvement – Twelve-Step Facilitation (TSF) treatments – had not been evaluated adequately. This systematic review and meta-analysis used the rigor of the Cochrane review system to subject AA/TSF to the same scientific standards as other clinical interventions.   (more…)
Author Interviews, Brigham & Women's - Harvard, JAMA, Nutrition, Social Issues / 09.03.2020

MedicalResearch.com Interview with: Alon Peltz, MD MBA MHS  Department of Population Medicine Harvard Pilgrim Health Care Institute MedicalResearch.com: What is the background for this study? Response: Thank you for taking an interest in our study. This study represented a collaboration between investigators from Harvard Medical School and Boston University School of Medicine. SNAP is an important U.S. federal aid program that serves nearly 40 million persons annually with well-established health, nutrition, and financial benefits. Families can be eligible for the SNAP program under “federal” rules or “categorical eligibility” rules that extend SNAP support to otherwise ineligible families who receive benefits under certain social assistance programs, such as Temporary Assistance for Needy Families. In July 2019, the U.S. Department of Agriculture proposed new SNAP policies that would limit qualifications via the categorical eligibility route. Although these new policies have not been finalized, it is estimated that 1 in 10 U.S. families currently participating in SNAP may lose their benefits. We wanted to investigate the potential ramifications of these changes to help inform policymakers of the vulnerabilities of the families who receive SNAP benefits and may be at risk for disenrollment if the proposed policies are implemented.

Author Interviews, BMJ, Brigham & Women's - Harvard, Heart Disease, Nutrition / 05.03.2020

MedicalResearch.com Interview with: Jean-Philippe Drouin-Chartier, RD PhD Assistant Professor, Faculty of Pharmacy, Université Laval Researcher, NUTRISS Center of INAF, Université Laval Visiting Scientist, Department of Nutrition Harvard TH Chan School of Public Health  MedicalResearch.com: What is the background for this study? Response: Cardiovascular disease (CVD) is a leading cause of death worldwide. Eggs are a major source of dietary cholesterol, but they are also an affordable source of high-quality protein, iron, unsaturated fatty acids, phospholipids, and carotenoids. However, because of the cholesterol content in eggs, the association between egg intake and CVD risk has been a topic of intense debate in the past decades. Many prospective studies on the association between egg intake and cardiovascular disease risk have provided conflicting findings. The aim of our study was to prospectively examine the association between egg consumption and risk of CVD in three cohorts of US men and women, and to conduct a systematic review and a meta-analysis of prospective cohort studies on eggs and CVD.  (more…)
Accidents & Violence, Author Interviews, Brigham & Women's - Harvard, JAMA, Pediatrics / 03.03.2020

MedicalResearch.com Interview with: Hooman Azad First author and a 3rd year medical student Feinberg School of Medicine Northwestern University Eric Fleegler, MD MPH FAAP Senior author and Pediatric Emergency Physician Boston Children’s Hospital Assistant Professor of Pediatrics and Emergency Medicine Harvard Medical School MedicalResearch.com: What is the background for this study? Response: Pediatric firearm violence is a public health crisis. The firearm fatality rate has increased by >50% over the past 10 years. Over our 26-year study period (1991-2016), 13,697 children under the age of 15 died at the hands of a firearm. Laws have been employed to try to reduce these deaths, and Child Access Prevention (CAP) laws, which aim to hold parents liable for the safe storage of their firearms, were passed in 25 states between 1989-2000. No new state passed a CAP laws after the year 2000. Child Access Prevention laws come in two flavors – recklessness laws that hold firearm owners liable for directly providing firearms to a minor, and negligence laws that hold the firearm owner liable for the unsafe storage of firearms with variability in how storage is defined and what penalties are imposed.

MedicalResearch.com Interview with: Nancy J. Donovan, M.D. Chief, Division of Geriatric Psychiatry Brigham and Women’s Hospital Assistant Professor of Psychiatry Harvard Medical School Boston, MA 02115  MedicalResearch.com: What is the background for this study? Response: Prior research has shown that widowed older adults are more likely to experience cognitive decline than those who are married. However, there have been no prior studies of widowhood as a risk factor for cognitive decline due to Alzheimer’s disease, the most common cause of severe cognitive impairment. (more…)
Annals Internal Medicine, Author Interviews, Breast Cancer, Brigham & Women's - Harvard, Cancer Research, Mammograms / 25.02.2020

MedicalResearch.com Interview with: Xabier Garcia-De-Albeniz MD PhD Research Associate Department of Epidemiology Harvard T.H. Chan School of Public Health Mongan Institute for Health Policy Massachusetts General Hospital  MedicalResearch.com: What is the background for this study? Response: The goal of breast cancer screening is to reduce deaths from breast cancer by finding breast cancer at early, more treatable stages. The main way to screen for breast cancer is periodic mammography, which is an x-ray of the breast that can show tumors before they are large enough to feel. High-quality studies called clinical trials have shown that screening women in their 50s and 60s decreases breast cancer deaths. However, the point at which women can safely stop screening because it no longer decreases breast cancer deaths has not been studied. More than half of women in the United States continue screening mammography after age 75 years.  (more…)
Author Interviews, Brigham & Women's - Harvard, Hearing Loss / 14.02.2020

MedicalResearch.com Interview with: Aravindakshan Parthasarathy, PhD Researcher, Massachusetts Eye and Ear Instructor in Otolaryngology–Head and Neck Surgery Harvard Medical School  MedicalResearch.com: What is the background for this study? Would you briefly explain what is meant by Hidden Hearing Loss? Response: Our ears were not designed for the society our brains created. The World Health Organization estimates that 1 billion young adults are at risk for hearing loss due to prolonged exposure to excessive environmental noise. Anatomical analysis of human ears has shown that half of the nerve fibers connecting the ear to the brain have degenerated by the time we reach 40 years of age. Many of us experience the first symptoms of hearing loss as a difficulty following conversations in crowded places such as restaurants. Hidden hearing loss is an umbrella term used to describe such hearing difficulties experienced by people who show no abnormalities on any of the current tests of hearing used in the clinic. Approximately 10% of visitors to our hospital hearing clinic fit this profile, arriving with a primary complaint of poor hearing but being sent home with a clean bill of hearing health.  (more…)

Asthma, Author Interviews, Brigham & Women's - Harvard, NEJM, Pediatrics, Vitamin D / 10.02.2020

MedicalResearch.com Interview with: Augusto A. Litonjua, M.D., M.P.H. Professor - Department of Pediatrics, Pulmonology Interim Chief - Department of Medicine , Pulmonary Diseases and Critical Care Professor - Department of Medicine , Pulmonary Diseases and Critical Care University of Rochester MedicalResearch.com: What is the background for this study? Response: Vitamin D deficiency and insufficiency is prevalent worldwide. Prior observational studies have shown that low vitamin D levels have been associated with the development of asthma. Animal studies have reported that antenatal vitamin D is important for lung development in utero. Thus, we conducted a randomized, double-blind, controlled trial of vitamin D supplementation in pregnant women to see if we could prevent the development of asthma and wheezing illnesses in young children. The initial report of the trial results showed that children born to mothers in the vitamin D supplementation arm had lower risks for developing either asthma or recurrent wheezing episodes over the first 3 years, but this was not statistically significant (p=0.051)(Litonjua et al. JAMA 2016). (more…)

MedicalResearch.com Interview with: Stephen P. Juraschek, MD, PhD Assistant Professor, Harvard Medical School Beth Israel Deaconess Medical Center Division of General Medicine, Section for Research Boston, MA  02215 MedicalResearch.com: What is the background for this study? Response: Gout is a common complication of blood pressure treatment. Furthermore, 75% of adults with gout have hypertension. There are several classes of medications uses to treat hypertension. While prior studies have reported that calcium channel blockers like amlodipine lower uric acid, its effects on gout risk compared to other common first-line antihypertensive agents are unknown.  (more…)
Author Interviews, Brigham & Women's - Harvard, JAMA, Nutrition / 22.01.2020

MedicalResearch.com Interview with: Zhilei Shan PhD Postdoctoral fellow on Nutritional Epidemiology Harvard T.H. Chan School of Public Health MedicalResearch.com: What is the background for this study? Response: Long-standing controversies have focused on the health consequences of dietary fat and carbohydrate. Previous evidence has shown that different types of carbohydrates and fats have varying effects on disease risk and health. For example, carbohydrates from refined grains and added sugars may contribute to insulin resistance and other metabolic problems while carbohydrates from whole grains and whole fruits appear to be beneficial. Likewise, replacing saturated fat with unsaturated fat was associated with lower risk of heart disease and mortality. Therefore, it is crucial to incorporate quality and types of carbohydrate and fat when investigating the associations of low-fat and low-carbohydrate diets with mortality. (more…)
Author Interviews, Breast Cancer, Brigham & Women's - Harvard, JAMA, Surgical Research / 08.01.2020

MedicalResearch.com Interview with: Mehra Golshan, MD, MBA Dr. Abdul Mohsen & Sultana Al-Tuwaijri Distinguished Chair Surgical OncologyDirector of Breast Surgical Oncology Fellowship Associate Professor, Harvard Medical School  MedicalResearch.com: What is the background for this study? What are the main findings? Response: Triple negative breast cancer is an aggressive form of breast cancer that often requires chemotherapy. In this study we provided neoadjuvant chemotherapy with or without a PARP inhibitor and showed that many women who were originally ineligible for breast conservation (lumpectomy) became eligible after treatment. If lumpectomy was tried it was usually successful.  Many more women in the US compared to Europe and Asia chose mastectomy when lumpectomy was an option even when genetics is negative. (more…)

MedicalResearch.com Interview with: Dr. D. Branch Moody, MD Principal Investigator Associate Physician, Brigham and Women's Hospital Professor of Medicine, Harvard Medical School MedicalResearch.com: What is the background for this study? Is the CD1a molecule found on the skin's Langerhans cells? Response: With increasing industrialization worldwide, people apply cosmetics and other consumer products to the skin, leading to contact dermatitis, which is becoming increasingly common. Immunologists know that T cells participate in dermatitis reactions. However, T cells usually recognize and respond to antigens that are peptides rather than the non-peptide antigens that cause contact dermatitis. (more…)
