Richard L. Kravitz, MD, MSPH Professor and Co-vice Chair (Research) Interim Director, UC Center Sacramento Co-Editor in Chief, Journal of General Internal MedicineMedicalResearch.com Interview with: Richard L. Kravitz, MD, MSPH Professor and Co-vice Chair (Research) Interim Director, UC Center Sacramento Co-Editor in Chief, Journal of General Internal Medicine MedicalResearch.com: What is the background for your study? Dr. Kravitz: Depression in the United States is both undertreated and overtreated.  As the de facto mental health care system for many, primary care is at the nexus of this problem.  Up to 30% of patients with major depression in primary care go undiagnosed.  At the same time, partly as a result of marketing, lots of patients who don’t need meds are started on antidepressants.   So we were interested in finding ways to get more truly depressed patients into treatment without overtreating patients who don’t need it.

MedicalResearch.com Interview with: Chris Fritz BSs PEZZ Center for Pediatric Endocrinology Zurich, Zurich, Switzerland MedicalResearch.com: What are the main findings of the study? Answer: Targeted strength training significantly increases daily spontaneous physical activity (PA) behaviour in boys. The less active children showed the greatest increase. 102 healthy school children were randomly placed in two groups. The control group continued three PE classes per week, whereas the intervention group had two out of three PE classes replaced by an individualised strength training program. At baseline there was no difference in anthropometry, body composition and PAEE between the groups. At the end of the training intervention, we found a significant increase of upper and lower body strength in the intervention group in boys and in girls. Boys significantly increased their PA by 10%. Without taking into account the energy expenditure during the strength training, the 10% PAEE increase corresponds to a weekly bike ride of 28 miles for a child of 40 kg body weight. Or in other words, an individualised school based strength training program increases energy expenditure outside the intervention by an equivalent of about 7kg of body fat corresponding to 10kg of chocolate per year.

Between 1986 and 1996, this phase III EORTC trial 10853 randomized 1010 women with complete local excision of DCIS to no further treatment (503 patients) or radiotherapy (507 patients). The risk of any local recurrence was found to be reduced by 48% in the patients who also received radiotherapy. The 15-year local recurrence-free rate was 69% for the group of patients receiving breast conserving surgery alone, but this increased to 82% for the group of patients who also received radiotherapy, and the 15-year invasive local recurrence-free rate was 84% versus 90%, respectively.

MedicalResearch.com Interview with: Jessica E. Galarraga, MD, MPH Resident Physician Department of Emergency Medicine George Washington University Hospital 2120 L. St. N.W. Suite 475 Washington D.C. Jessica E. Galarraga, MD, MPH Resident Physician Department of Emergency Medicine George Washington University Hospital 2120 L. St. N.W. Suite 475 Washington D.C.   MedicalResearch.com: What are the main findings of the study? Dr. Galarraga: This study examined how emergency department (ED) reimbursements for outpatient visits may be impacted by the insurance coverage expansion of the Patient Protection and Affordable Care Act as newly eligible patients gain coverage either through the Medicaid expansion or through health insurance exchanges. We conducted our analyses using the Medical Expenditure Panel Survey, a nationally representative survey managed by the Agency for Healthcare Research and Quality. We found that ED reimbursements for outpatient encounters by the previously uninsured who gain Medicaid insurance may increase by  17 percent and moving Medicaid-expansion ineligible patients to the private insurance market through insurance exchanges may increase reimbursements as high as 39 percent after the act is implemented.

Dr. Soliman: Using data from the REGARDS study, one of the largest US cohorts, we examined the risk of incident myocardial infarction (MI) associated with atrial fibrillation (AF). Overall, AF was associated with almost double the risk of MI. When we adjusted for common cardiovascular risk factors and potential confounders, the risk remained significantly high; about 70% increased risk. When we looked at women, men, blacks, and whites separately,  we found significant differences between races and sex.  AF in women and blacks was associated with more than double the risk of MI. This compares to less than 50% increased risk of heart attack associated with AF in men and whites . So AF is basically bad for all, but the risk of MI associated with AF is more pronounced in women and blacks. (more…)

Dr. Pedrique: Of the 850 new drugs and vaccines approved for all diseases in 2000-2011, 4% (37) were for neglected diseases, defined broadly as those prevalent primarily in poor countries: malaria, tuberculosis, 17 neglected tropical diseases (NTDs) as defined by the World Health Organization (WHO), 11 diarrheal diseases, and 19 other diseases of poverty, excluding HIV/AIDS. Globally these neglected diseases represent an 11% health burden, based on a recent assessment of 2010 disability-adjusted life-years (DALYs). Most newly developed therapeutic products were repurposed versions of existing drugs. Of the 336 brand-new drugs (new chemical entities, or NCEs) approved for all diseases in 2000-2011, only four, or 1%, were for neglected diseases; three were for malaria, and one for diarrheal disease. None were for any of the 17 WHO-listed NTDs Of 148,445 phase I-III clinical trials registered as of Dec 31, 2011, only 1% (2,016) were for neglected diseases. (more…)

MedicalResearch.com Interview with: Reina Haque, PhD, MPH Research scientist, Kaiser Permanente Department of Research & Evaluation MedicalResearch.com: What are the main findings of the study? Answer: The main study findings are that men who are overweight or obese when they are diagnosed with prostate cancer are more likely to die from the disease than men who are of healthy weight. In patients with more aggressive forms of prostate cancer, the researchers also found an even stronger correlation between obesity and mortality. The study was restricted to patients undergoing surgical treatment for prostate cancer, rather than other treatments such as radiation or hormone therapy. (more…)

Response: The main finding of the study is that lifestyle advice with respect to mortality for patients with diabetes should not differ from recommendations for the general population. Diabetes status did not substantially influence the associations between lifestyle and mortality risk. People with diabetes may benefit more from a healthy diet, but the directions of association were similar. These results highlight that the difficulties in recognizing and diagnosing diabetes and its different stages are of minor importance with respect to healthy diet and lifestyle recommendations, because no difference in recommendations depending on the stage of the disease seems necessary.

MedicalResearch.com Interview Jennifer M. Poti PhD Candidate, Nutritional Epidemiology University of North Carolina at Chapel Hill MedicalResearch.com: What are the main findings of the study? Answer: Consumption of solid fat and added sugar (SoFAS) by children exceeds recommendations, but it was not known where kids obtain these “empty calories.” Analyzing data from over 22,000 US children, we found that children consumed about 1/3 of their calories as solid fat and added sugar for foods consumed from retail food stores (including grocery stores and supermarkets), schools, or fast food restaurants in 2009-2010, despite significant decreases from 1977 to 2010 at each location. These mean levels of empty calorie intake greatly exceeded recommended amounts not just for fast foods, but also for foods consumed from schools and from stores. For all survey years, foods consumed by children from schools were higher in solid fat content than foods obtained and consumed from retail food stores. (more…)

Dr. Brzustowicz: The objective of this study was to search for locations in the human genome that impact language ability in individuals with autism as well as in their family members without autism.  To do this, we recruited families with an individual with autism and at least one other family member without autism but with a language learning impairment.  We identified two locations in the human genome that are linked to language ability in these families.  Importantly, these locations do not appear to be specific to language impairment in the individuals with autism, but are related to language ability in other family members as well.  This suggests that while individuals with autism may have new, or de novo, genetic variations that are important for risk of illness, they may also carry inherited genetic variation that influence the expression of their illness.  The effects of these inherited variants can also be seen in the language performance of family members without autism.
