Author Interviews, Brigham & Women's - Harvard, Cannabis, Pediatrics, Pediatrics / 07.11.2017

MedicalResearch.com Interview with: Shane Shucheng Wong, MD Massachusetts General Hospital Boston, Massachusetts  MedicalResearch.com: What is the background for this study? Response: Medical cannabis is now legal in 29 states and the District of Columbia, and in those areas with active programs, children and adolescents can legally access medical cannabis with certification from their doctor and consent from a parent. This means that doctors and families need to understand what we know and what we don’t yet know about medical cannabis in order to make the best decision for the health of the individual child. Two synthetic cannabinoids – compounds that act on specific receptors in the brain – have been approved for medical use in the U.S., both of which mimic a form of THC (tetrahydrocannabinol), the compound responsible for the “high” of recreational cannabis use. Dronabinol (Marinol) is approved to treat chemotherapy-induced nausea and vomiting in both children and adults, while the pediatric use of nabilone (Cesamet) carries a caution. A third cannabinoid, cannabidiol, is currently in phase 3 trials for treatment of seizures. (more…)
Author Interviews, Brigham & Women's - Harvard, Chocolate, Pediatrics, Weight Research / 01.11.2017

MedicalResearch.com Interview with: Jorge E. Chavarro, MD, ScD Associate Professor Departments of Nutrition and Epidemiology Harvard T.H. Chan School of Public Health Channing Division of Network Medicine Department of Medicine Brigham and Women’s Hospital and Harvard Medical School Boston, MA 02115 MedicalResearch.com: What is the background for this study? What are the main findings? Response: It is well known that sugared sweetened beverages (SSBs) promote excessive weight gain and obesity in children. The excess sugars in chocolate milk and other flavored milks puts them in a category that may be closer to sugared sweetened beverages than to plain milk. However, data on whether flavored milks promote weight gain is scarce. We followed a cohort of 5,321 children and adolescents over a four year period to evaluate whether intake of chocolate milks was related to weight gain. We found that children who increased their intake of flavored milk gained more weight than children whose intake of flavored milk remained stable over this period. Moreover, among those children who did not drink any chocolate milk at baseline, those who started drinking chocolate milk over the course of the study gained substantially more weight than children who remained non-consumers of chocolate milk.

Author Interviews, Brigham & Women's - Harvard, Environmental Risks, JAMA, OBGYNE / 01.11.2017

MedicalResearch.com Interview with: Yu-Han Chiu, M.D., M.P.H., Sc.D Department of Nutrition Harvard T.H. Chan School of Public Health MedicalResearch.com: What is the background for this study? What are the main findings? Response: Animal experiments suggest that ingestion of pesticide mixtures at environmentally relevant concentrations decreases the number of live-born pups. However, it is unclear whether intake of pesticide residues has any adverse effects in humans, especially for susceptible populations such as pregnant women and their fetuses. Therefore, in this study we examined the association of preconception intake of pesticide residues in fruits and vegetables with pregnancy outcomes among 325 women undergoing assisted reproduction. A pesticide is far cheaper than pest control services, like termite control los angeles, so it makes sense why most farmers choose to use pesticide for their farmhouse and crops. However, this isn't necessarily the best procedure for human health, or consumption! We found that intake of high pesticide residue fruits and vegetables were associated with higher risks of pregnancy loss, while low pesticide residue fruit and vegetable intake was associated with lower risks of early pregnancy loss. These data suggest dietary pesticide exposure within the range of typical human exposure may be associated with adverse reproductive consequences (more…)
Author Interviews, Breast Cancer, Brigham & Women's - Harvard, Cancer Research, Mammograms, Technology / 20.10.2017

MedicalResearch.com Interview with: Manisha Bahl, MD, MPH Director, Breast Imaging Fellowship Program, Massachusetts General Hospital Assistant Professor of Radiology, Harvard Medical School MedicalResearch.com: What is the background for this study? What are the main findings? Response: Image-guided biopsies that we perform based on suspicious findings on mammography can yield one of three pathology results: cancer, high-risk, or benign. Most high-risk breast lesions are noncancerous, but surgical excision is typically recommended because some high-risk lesions can be upgraded to cancer at surgery. Currently, there are no imaging or other features that reliably allow us to distinguish between high-risk lesions that warrant surgery from those that can be safely followed, which has led to unnecessary surgery of high-risk lesions that are not associated with cancer. We decided to apply machine learning algorithms to help us with this challenging clinical scenario: to distinguish between high-risk lesions that warrant surgery from those that can be safely followed. Machine learning allows us to incorporate the full spectrum of diverse and complex data that we have available, such as patient risk factors and imaging features, in order to predict which high-risk lesions are likely to be upgraded to cancer and, ultimately, to help our patients make more informed decisions about surgery versus surveillance. We developed the machine learning model with almost 700 high-risk lesions, then tested it with more than 300 high-risk lesions. Instead of surgical excision of all high-risk lesions, if those categorized with the model to be at low risk for upgrade were surveilled and the remainder were excised, then 97.4% malignancies would have been diagnosed at surgery, and 30.6% of surgeries of benign lesions could have been avoided.

Author Interviews, Brigham & Women's - Harvard, Cost of Health Care, JAMA, OBGYNE / 03.10.2017

MedicalResearch.com Interview with: Andrew L. Beam, PhD Instructor in Biomedical Informatics Department of Biomedical Informatics Harvard Medical School MedicalResearch.com: What is the background for this study? What are the main findings? Response: This study is one piece of a larger story regarding the use of 17-alpha-hydroxyprogesterone caproate (17P) to treat recurrent preterm birth. This drug was originally only available in a compounded form, but since receiving an orphan drug designation in 2011, a branded and manufactured form was marketed under the name "Makena". This branded form was then sold for a much higher price than the compounded version, but a study that provided concrete data on pricing and outcomes had not been done. (more…)
Author Interviews, Brigham & Women's - Harvard, Cost of Health Care, JAMA, Nutrition / 27.09.2017

MedicalResearch.com Interview with: Seth A. Berkowitz, MD, MPH Division of General Internal Medicine Diabetes Population Health Unit Harvard Medical School Massachusetts General Hospital, Boston MedicalResearch.com: What is the background for this study? What are the main findings? Response: There is ever growing pressure to contain healthcare costs in the US. Increasingly, attention is turning to programs that address social determinants of health--that is, those factors which affect health but lie outside the realm of clinical medicine. Prior research has highlighted food insecurity as having a clear association with poor health and higher healthcare costs. SNAP is the nation's largest program to combat food insecurity. However, we did not know whether SNAP participation would be associated with any difference in healthcare costs, compared with eligible non-participants. This study found that participating in SNAP was associated with approximately $1400 lower healthcare expenditures per year in low-income adults. (more…)
Author Interviews, Brigham & Women's - Harvard, Heart Disease, JAMA, Orthopedics / 22.09.2017

MedicalResearch.com Interview with: Avinainder Singh, M.B.B.S. Research Fellow Cardiovascular Medicine Brigham & Women's Hospital Harvard Medical School Boston, MA MedicalResearch.com: What is the background for this study? Response: Amyloidosis due to aberrant folding of proteins. These misfolded proteins can deposit in various parts of the body and lead to organ dysfunction. The two most common types of amyloidosis affecting the heart include transthyretin and light chain amyloidosis. Transthyretin is a protein produced by the liver which supports the transport of thyroxine and retinol. Wild-type transthyretin amyloidosis (ATTRwt, previously known as senile amyloidosis) occurs due to deposition of misfolded fibrils derived from transthyretin and primarily affects elderly men. Once considered a rare disease, it is now reported to be responsible for nearly 13% of heart failure with preserved ejected fraction and increased wall thickness. Rupture of the biceps tendon is a rare occurrence in the general population (<1 per 1000). We noticed a ruptured biceps tendon in several patients with wild-type transthyretin amyloidosis and performed this study to further evaluate this finding in a group of patients with wild-type transthyretin amyloidosis and in a control group of age-matched patients with non-amyloid heart failure.

MedicalResearch.com Interview with: Muthiah Vaduganathan, MD, MPH Brigham and Women’s Hospital Heart & Vascular Center and Harvard Medical School Boston, Massachusetts MedicalResearch.com: What is the background for this study? What are the main findings? Response: The CardioMEMS™ HF System (Abbott, Sylmar, CA) is a commercially-available, wireless hemodynamic monitor that can be permanently implanted in the pulmonary artery (PA) to permit real-time, remote monitoring of PA pressures to enhance clinical decision-making in patients with heart failure (HF). Based on a favorable safety profile and the results of the CHAMPION trial, the US Food and Drug Administration (FDA) approved the device in May 2014. Since FDA approval, the device is being implanted in older patients with greater comorbidities compared with those enrolled in CHAMPION. Limited safety data are available after market introduction in this higher-risk pool. (more…)
Author Interviews, Brigham & Women's - Harvard, Endocrinology, Hormone Therapy, JAMA, Menopause / 13.09.2017

MedicalResearch.com Interview with: JoAnn E. Manson, MD, DrPH Chief, Division of Preventive Medicine Brigham and Women's Hospital Professor of Medicine and the Michael and Lee Bell Professor of Women's Health Harvard Medical School Boston, Massachusetts  02215  MedicalResearch.com: What is the background for this study? Response: The current report provides new information on total mortality and the rates of death from specific causes (cardiovascular disease, cancer, other major illnesses) over 18 years of follow-up in the Women’s Health Initiative (WHI) randomized trials of hormone therapy (estrogen + progestin and estrogen alone). This is the first WHI report to focus on all-cause and cause-specific mortality. It includes all of the 27,347 women in the 2 hormone therapy trials with >98% follow-up over 18 years, during which time 7,489 deaths occurred. This is more than twice as many deaths as were included in earlier reports. The report also provides detailed information on differences in results by age group (ages 50-59, 60-69, 70-79) at time of study enrollment. (more…)

MedicalResearch.com Interview with: Leslie V. Farland, ScD Assistant Director of Epidemiologic Research Center for Infertility and Reproductive Surgery Brigham and Women's Hospital | Harvard Medical School Instructor | Harvard T.H. Chan School of Public Health MedicalResearch.com: What is the background for this study? Response: Endometriosis is chronic gynecologic condition that affects approximately ten percent of women. Women with endometriosis can experience painful menstrual periods, general chronic pelvic pain, and pain associated with intercourse. Currently we know very few modifiable risk factors for endometriosis. (more…)
Allergies, Author Interviews, Brigham & Women's - Harvard, Pediatrics, Technology / 07.09.2017

MedicalResearch.com Interview with: Lee, Hakho, PhD Department of Systems Biology Harvard Medical School Boston, Massachusetts MedicalResearch.com: What is the background for this study? What are the main findings? Response: The incidence of food allergy is increasing worldwide, particularly among children, and yet no handy test is available for general public. There are plenty of allergens testing methods for the factories producing the products, we wanted to solve this issue. Our pilot test showed wide variation in allergen contents in packaged food products and restaurant meals. Hidden allergens (like gluten in salad dressing, likely from additives) were also found.

Author Interviews, BMJ, Brigham & Women's - Harvard, Opiods, Pediatrics / 04.08.2017

MedicalResearch.com Interview with: Krista F. Huybrechts, MS PhD Assistant Professor of Medicine Brigham and Women’s Hospital Harvard Medical School Boston, MA 02120 MedicalResearch.com: What is the background for this study? What are the main findings? Response: Neonatal drug withdrawal is common; in the U.S. about 1 infant is born every 25 minutes with signs of drug withdrawal. Neonatal drug withdrawal is a well-recognized complication of intrauterine exposure to illicit or prescription opioids, but other psychotropic medications can also cause signs of withdrawal. Psychotropic medications are frequently co-prescribed with opioids in pregnancy, and the use of both has increased significantly, raising concerns about an increase in the incidence and severity of neonatal drug withdrawal due to potential drug-drug interactions, but these risks are not well understood. In this study, we found a 30-60% increase in the risk of neonatal drug withdrawal associated with co-exposure to antidepressants, benzodiazepines and gabapentin, compared to opioids alone; no significant increase in risk was observed for atypical antipsychotics and Z-drugs. Exposure to psychotropic polypharmacy along with opioids was associated with a two-fold increased risk of withdrawal. (more…)
Author Interviews, Blood Pressure - Hypertension, Brigham & Women's - Harvard, JAMA / 28.07.2017

MedicalResearch.com Interview with: Stephen P. Juraschek, MD, PhD Instructor of Medicine Beth Israel Deaconess Medical Center Harvard Medical School MedicalResearch.com: What is the background for this study? Response: Many adults experience dizziness and light-headedness when they stand up. This is more common in older adults and is related to risk of falling, fractures, fainting, car crashes, and early death. These symptoms are thought to be caused by a drop in blood pressure after standing also called orthostatic hypotension. However, if measured at the wrong time it is possible to miss this important clinical sign. For over 2 decades (since 1996), it has been recommended that orthostatic hypotension be identified by measuring blood pressure within 3 minutes of standing. Furthermore, it was also thought that measurements immediately after standing be avoided because they might be inaccurate (based on fluctuation in blood pressure immediately after standing). As a result, a lot of clinical protocols instructing healthcare staff on measuring orthostatic blood pressure encourage measurement at 3 minutes, but this has not been scientifically evaluated.

Annals Internal Medicine, Author Interviews, Brigham & Women's - Harvard, Hormone Therapy, Sexual Health, Testosterone / 27.07.2017

MedicalResearch.com Interview with: Carl G Streed Jr. M.D. Pronouns: he, him, his, himself Fellow, Division General Internal Medicine & Primary Care Brigham & Women’s Hospital  MedicalResearch.com: What is the background for this study? What are the main findings? Response: Recent reports estimate that 0.6% of adults in the United States, or approximately 1.4 million persons, identify as transgender. Despite gains in rights and media attention, the reality is that transgender persons experience health disparities, and a dearth of research and evidence-based guidelines remains regarding their specific health needs. The lack of research to characterize cardiovascular disease (CVD) and CVD risk factors in transgender populations receiving cross-sex hormone therapy (CSHT) limits appropriate primary and specialty care. As with hormone therapy in cisgender persons (that is, those whose sex assigned at birth aligns with their gender identity), existing research in transgender populations suggests that CVD risk factors are altered by CSHT.

Annals Internal Medicine, AstraZeneca, Author Interviews, Brigham & Women's - Harvard, Heart Disease, Merck, Pharmacology / 25.07.2017

MedicalResearch.com Interview with: Alexander Turchin, MD,MS Director of Quality in Diabetes Associate Professor, Harvard Medical School Brigham and Women's Hospital Boston, MA MedicalResearch.com: What is the background for this study? Response: Cardiovascular disease is the # 1 cause of death in the U.S. and worldwide. Statins are some of the most effective medications available for prevention of cardiovascular events. However, many patients stop statins, frequently because of adverse reactions. In our study we aimed to assess the risk-benefit balance of trying a statin again after experiencing an adverse reaction.

MedicalResearch.com Interview with: Holly Gooding, MD, MSc Assistant Professor of Medicine and Pediatrics Harvard Medical School Division of Adolescent/Young Adult Medicine Boston Children's Hospital Division of General Internal Medicine Brigham and Women's Hospital Boston, MA MedicalResearch.com: What is the background for this study? What are the main findings? Response: Dr Stephanie Chiuve and colleagues at the Harvard TH Chan School of Public Health developed the Healthy Heart Score to predict the risk of heart disease in older adults based on lifestyle factors measured in middle age. We have known for some time that the precursor to heart disease – known as atherosclerosis – actually starts in childhood and adolescence. We calculated the Healthy Heart Score for young adults ages 18-30 years old and found it works in this age group as well.

Aging, Author Interviews, Brigham & Women's - Harvard, JAMA, Weight Research / 19.07.2017

MedicalResearch.com Interview with: Yan Zheng Research Fellow, Department of Nutrition Harvard T.H. Chan School of Public HealthYan Zheng Research Fellow, Department of Nutrition Harvard T.H. Chan School of Public Health MedicalResearch.com: What is the background for this study? What are the main findings? Response: Most people gain weight cumulatively during young and middle adulthood. Because the amount of weight gain per year may be relatively small, it may go unnoticed by individuals and their doctors—but the cumulative weight gain during adulthood may eventually lead to obesity over time. Compared to studies of attained body weight or BMI, the investigation of weight change may better capture the effect of excess body fat because it factors in individual differences in frame size and lean mass.

Author Interviews, Brigham & Women's - Harvard, Cancer Research, Dermatology, HIV, JAMA, Kaiser Permanente, Merck / 13.07.2017

MedicalResearch.com Interview with: Maryam M. Asgari, MD, MPH Department of Dermatology Massachusetts General Hospital, Department of Population Medicine Harvard Medical School, Boston, Massachusetts Division of Research, Kaiser Permanente Northern California, Oakland MedicalResearch.com: What is the background for this study? What are the main findings? Response: Nonmelanoma skin cancer – defined as basal cell carcinoma (BCC) and squamous cell carcinoma (SCC) – is a common malignant condition, affecting more than 2 million Americans every year. BCCs are more common than SCCs among individuals with healthy immune systems, while SCCs are more predominate than BCCs among people who are immunocompromised. We examined how laboratory markers used to evaluate HIV disease progression may be associated with subsequent nonmelanoma skin cancer risk in white patients previously diagnosed with at least one such cancer from 1996 to 2008.  We measured CD4 count, viral load and subsequent nonmelanoma skin cancer. The study included 455 participants with HIV and 1,952 without HIV. All were members of the Kaiser Permanente Northern California health care plan. (more…)
Author Interviews, Brigham & Women's - Harvard, Lifestyle & Health, NEJM, Nutrition / 13.07.2017

MedicalResearch.com Interview with: Mercedes Sotos Prieto PhD Research Fellow Department of Nutrition Harvard T. H. Chan School of Public Health MedicalResearch.com: What is the background for this study? What are the main findings? Response: Previous research have found that adherence to the 2010 Alternate Heathy Eating Index, the Mediterranean Diet pattern, and DASH pattern is associated with health benefits, but none of those studies have examined dynamic changes in diet quality over time and subsequent risk of mortality. This is the first study to demonstrate that improvement in these three diet scores over time is associated with reduced risk of total and cardiovascular mortality. In contrast, worsening diet quality over 12-years was associated with 6%-12% increased mortality. In addition, not only improvement in diet quality but maintaining a high adherence to any of the three dietary patterns over 12 years was significantly associated with 9%-14% lower total mortality.

Author Interviews, Brigham & Women's - Harvard, Cancer Research, Dermatology, JAMA / 07.07.2017

MedicalResearch.com Interview with: Dr. Chrysalyne D. Schmults, MD, MSCE Associate Professor of Dermatology, Harvard Medical School Director, Mohs and Dermatologic Surgery Center and Mr. Pritesh S. Karia, MPH Department of Epidemiology Johns Hopkins Bloomberg School of Public Health, Baltimore, Maryland Department of Dermatology Brigham and Women's Faulkner Hospital Harvard Medical School, Boston, Massachusetts Jamaica Plain, MA 02130-3446  MedicalResearch.com: What is the background for this study? Response: Perineural nerve invasion (PNI) is a well-recognized risk factor for poor prognosis in patients with cutaneous squamous cell carcinoma (CSCC). Most cases of CSCC with PNI are identified on histologic examination at the time of surgery and the patient has no clinical symptoms or radiologic evidence of PNI. These cases are classified as incidental PNI (IPNI). However, some patients with PNI present with clinical symptoms and/or radiologic evidence of PNI. These cases are classified as clinical PNI (CPNI). A few studies have shown differences in disease-related outcomes between CSCC patients with IPNI and CPNI but consensus regarding adjuvant treatment and detailed guidelines on follow-up schedules have not yet materialized.

Author Interviews, Brigham & Women's - Harvard, Environmental Risks, NEJM, Race/Ethnic Diversity / 29.06.2017

MedicalResearch.com Interview with: Qian Di, M.S, Doctoral Student Department of Environmental Health and Francesca Dominici, Ph.D. Principal Investigator of this study Professor of Biostatistics co-Director of the Harvard Data Science Initiative Harvard T.H. Chan School of Public Health Boston, MA MedicalResearch.com: What is the background for this study? What are the main findings? Response: The Clean Air Act requires Environmental Protection Agency to set National Ambient Air Quality Standard (NAAQS). Currently the annual NAAQS for PM2.5 is 12 microgram per cubic meter; and there is no annual or seasonal ozone standard. However, is current air quality standard stringent enough to protect human health? This is our main motivation. We conducted the largest attainable cohort study, including over 60 million Medicare participants, to investigate the association between long-term exposure to ozone/PM2.5 and all-cause mortality. We found significant harmful effect of PM2.5 even below current NAAQS. Each 10 microgram per cubic meter increase in PM2.5 is associated with 13.6% (95% CI: 13.1%~14.1%) increase in all-cause mortality. For ozone, 10 ppb increase in ozone exposure is associated with 1.1% (95% CI: 1.0%~1.2%) increase in mortality. Also, there is no appreciable level below which mortality risk tapered off. In other words, there is no “safe” level for PM2.5 and ozone. In other words, if we would reduce the annual average of PM2.5 by just 1 microgram per cubic meter nationwide, we should save 12,000 lives among elder Americans every year; 5 microgram --- 63,817 lives every year. Similarly, if we would reduce the annual summer average of ozone by just 1 ppb nationwide, we would save 1,900 lives every year; 5 ppb --- 9537 lives. Besides, we found black people, males and people of low SES are more vulnerable to air pollution. (more…)
Author Interviews, Brigham & Women's - Harvard, Dermatology, Melanoma / 22.06.2017

MedicalResearch.com Interview with: David E. Fisher MD, PhD Edward Wigglesworth Professor & Chairman Dept of Dermatology Director, Melanoma Program MGH Cancer Center Director, Cutaneous Biology Research Center Massachusetts General Hospital Harvard Medical School Boston, MA 02114 MedicalResearch.com: What is the background for this study? What are the main findings? Response: This study grew from an interest to mimic the dark pigmentation patterns in human skin which are known from epidemiology to be associated with low skin cancer risk. In the current work, a molecular inhibitor of the SIK enzyme was used to block the inhibitory action of SIK relative to melanin synthesis. The result was stimulation of dark pigmentation within human skin. (more…)
Author Interviews, Blood Pressure - Hypertension, Brigham & Women's - Harvard, Neurological Disorders, Stroke / 22.06.2017

MedicalResearch.com Interview with: Andrea Morotti, M.D. Research Fellow in Neurology Massachusetts General Hospital Harvard Medical School MedicalResearch.com: What is the background for this study? What are the main findings? Response: The CT angiography (CTA) spot sign is a validated marker of Intracerebral Hemorrhage (ICH) expansion and may identify those subjects more likely to benefit from intensive blood pressure reduction. We observed that less than 20% of ICH patients received a CTA as part of their diagnostic workup in a large, international randomized clinical trial. The performance of the spot sign in predicting ICH growth was suboptimal compared with what was reported in previous studies. Intensive blood pressure reduction did not improve functional outcome in spot sign positive patients. (more…)
Author Interviews, Brigham & Women's - Harvard, Education, PLoS, Sleep Disorders / 21.06.2017

MedicalResearch.com Interview with: Dr. Dorothee Fischer Department of Environmental Health Harvard T.H. Chan School of Public Health, Boston, Massachusetts Center for Injury Epidemiology, Liberty Mutual Research Institute for Safety Hopkinton, Massachusetts, MedicalResearch.com: What is the background for this study? What are the main findings? Response: Chronotypes are a result of how the circadian clock embeds itself into the 24h light-dark cycle, producing earlier and later individuals ("larks and owls") with regards to rhythms in physiology, cognition and behavior, including sleep. It can be beneficial for health and safety to sync forced wake times (work, school) with individual chronotypes, thereby reducing the misalignment between sleep, circadian rhythms and external demands. To better inform potential interventions such as tailored work schedules, more information is needed about the prevalence of different chronotypes and how chronotype differs by age and sex. To the best of our knowledge, this is the first large-scale and nationally representative study of chronotypes in the US. (more…)
Author Interviews, Brigham & Women's - Harvard, NEJM, Ophthalmology / 08.06.2017

MedicalResearch.com Interview with: Elisabetta Patorno, MD, DrPH Assistant Professor of Medicine, Harvard Medical School Division of Pharmacoepidemiology and Pharmacoeconomics, Department of Medicine, Brigham and Women's Hospital MedicalResearch.com: What is the background for this study? Response: Lithium, a widely used medicine to treat bipolar disorder, has been associated with a 400 fold increased risk of Ebstein’s anomaly, a congenital malformation of the heart, and a 5 fold increased risk of cardiac defects overall in infants when taken early in pregnancy, based on the results from the International Register of Lithium Babies in the 1970’s. Beyond this data, most of the information on the safety of lithium during pregnancy accumulated in the last 40 years is based on case reports and small studies with conflicting results. Despite these concerns and the limited information, lithium remains a first-line treatment for the 1% of women of reproductive age with bipolar disorder in the U.S. population, due to its recognized efficacy during pregnancy and the postpartum period, and due to the presence of a larger body of evidence showing increased risk of congenital malformations for other mood stabilizers, such as valproate.

Author Interviews, Brigham & Women's - Harvard, Gender Differences, JAMA, Mental Health Research / 05.06.2017

MedicalResearch.com Interview with: Carl G Streed Jr. M.D. Pronouns: he, him, his, himself Fellow, Division General Internal Medicine & Primary Care  Brigham & Women’s Hospital MedicalResearch.com: What is the background for this study? What are the main findings? Response: The National Institutes of Health (NIH) has underscored the need to better understand the health of gender minorities, including transgender and gender non-conforming individuals. Prior investigations of gender minorities are limited by the lack of national gender identity data. In 2013, the Centers for Disease Control and Prevention (CDC) developed a gender identity question for the Behavioral Risk Factors Surveillance System (BRFSS); states had the option to administer this module beginning 2014. Our study aims to examine the health status of gender minorities in the US compared to cisgender peers. Compared to cisgender adults, gender minority adults are younger, less likely to be non-Hispanic white, married or living with a partner, have a minor child in the household, or be English speaking; but are more likely to have lower income, be unemployed, be uninsured, have unmet medical care due to cost, be overweight, and report depression. Gender minority adults, compared to cisgender adults, are more likely to report: poor or fair health; difficulty concentrating, remembering, or making decisions; and being limited in any way. These outcomes remained significant after adjustment. (more…)
Allergies, Asthma, Author Interviews, Brigham & Women's - Harvard, Social Issues / 31.05.2017

MedicalResearch.com Interview with: Wanda Phipatanakul, MD, MS Associate Professor of Pediatrics Harvard Medical School Director, Asthma Clinical Research Center Boston Children's Hospital Asthma, Allergy and Immunology Boston, MA 02115 MedicalResearch.com: What is the background for this study? What are the main findings? Response: Observational studies have limitations in their ability to examine disparities in asthma, as these studies have relied on self-reported measures of medication use, asthma diagnosis, severity, outcomes, and access to care. Using data collected from a randomized controlled trial, we found that subjects with lower income had a significantly higher number of asthma treatment failures and asthma exacerbations, independent of race, BMI, education, perceived stress, baseline lung function, hospitalizations, inhaled corticosteroid adherence, inhaled corticosteroid dose, environmental allergen sensitization, and second-hand smoke exposure.

MedicalResearch.com Interview with: Yusuke Tsugawa, MD, MPH, PhD Harvard T. H. Chan School of Public Health Department of Health Policy and Management Cambridge, MA 02138 MedicalResearch.com: What is the background for this study? What are the main findings? Response: Although evidence has suggested that older physicians may experience a decline in medical knowledge and are less likely to adhere to standard care, patients in general had a perception that older doctors are more experienced and therefore provide superior care. Using a nationally representative sample of Medicare beneficiaries who were hospitalized for medical conditions in 2011-2014, we found that patients treated by younger doctors have lower 30-day mortality compared to those cared for by older doctors, after adjusting for patient, physician, and hospital characteristics.

Author Interviews, Brigham & Women's - Harvard, Cost of Health Care / 17.05.2017

MedicalResearch.com Interview with: Eric Roberts, PhD Post-doctoral fellow Department of Health Care Policy Harvard Medical School MedicalResearch.com: What is the background for this study? What are the main findings? Response: Increasing consolidation of health care providers has raised regulatory concerns that less competition will lead to higher health care prices and possibly lower quality care for patients. On the other hand, some industry observers have contended that larger and higher-priced practices are better able invest in systems to support care management, and ultimately, better patient care. In this study, we examined whether larger and higher-priced physician practices provided better and more efficient care to their patients. Higher-priced physician groups were paid an average of 36% more by commercial insurers, and were substantially larger than lower-priced practices located within the same geographic areas. Despite large differences in practices’ prices and size, we found few differences in their patients’ quality and efficiency of care. For example, when we compared patients who received care in high-priced versus low-priced practices, we found no differences in patients’ overall care ratings, physician ratings, access to care, physician communication, and use of preventive services. We also found no differences in patients’ hospital admissions or total spending, suggesting that higher-priced practices were not managing their patients’ care more efficiently than their lower-priced counterparts. We did find that patients in higher-priced practices were more likely to receive recommended vaccinations, review of their medications, and results of medical tests, and that they spent less time in the waiting room for a scheduled doctor’s appointment. However, once practice prices exceeded the average for their geographic area, we observed no further gains in quality on most of these measures. (more…)
