Gabriel Arefalk Department of Medical Sciences Uppsala University Hospital Uppsala, SwedenMedicalResearch.com: Interview with: Gabriel Arefalk Department of Medical Sciences Uppsala University Hospital Uppsala, Sweden Medical Research: What are the main findings of the study? Answer: In this prospective cohort study, we investigated mortality risk in 2474 smokeless tobacco users who had been hospitalized for a myocardial infarction between the years of 2005-2009 in Sweden. We used a nationwide quality register and database called SWEDEHEART and found that those who stopped using snus (the Swedish type of snuff) after their MI had half the risk of dying during follow up relative to those who continued to use snus. This association, which was of the same magnitude as for smoking cessation, seemed to be independent of age, gender and smoking habits, as well as of many other relevant covariates. (more…)

Michael A. Collins PhD Professor of Molecular Pharmacology Loyola University Chicago Stritch School of Medicine Maywood IL 60153MedicalResearch.com Interview with: Michael A. Collins PhD Professor of Molecular Pharmacology Loyola University Chicago Stritch School of Medicine Maywood IL 60153 Medical Research: What are the main findings of your study? Dr. Collins: There were several:
  • First, we found that a cadre of neuroinflammatory proteins which promote or are stimulated by increased oxidative stress were significantly altered in a brain neurodegeneration model involving high alcohol binges in adult (male) rats. Most surprising was that the alterations were selectively evident in the three brain regions that contain a lot of dying neurons, and not in regions lacking neurodamage.
  • Additionally, in an alcohol-binged adult rat brain cultures, the same neuroinflammatory protein alterations, along with the neuronal damage, were replicated.
  • We further observed that binging the cultures depleted a key omega-3 fatty acid, termed DHA, in brain membranes. When these binged brain cultures were then supplemented with DHA, the neuroinflammatory protein changes and the neurodegeneration were largely or completely inhibited.
  • The results link specific oxidative stress-associated neuroinflammatory routes to the brain neuronal demise arising from high binge alcohol exposures.
  • They also reveal that supplementation with an omega-3 fatty acid reported to be neuroprotective with respect to other insults may be effective as well in suppressing the brain-damaging effects of excessive alcohol binges.

MSteven M. Hill, Ph.D. Professor, Structural & Cellular Biology Edmond & Lily Safra Chair for Breast Cancer Research Co-Director, Molecular Signaling Program, Louisiana Cancer Research Consortium Director, Tulane Circadian Biology CenteredicalResearch.com Interview with Steven M. Hill, Ph.D. Professor, Structural & Cellular Biology Edmond & Lily Safra Chair for Breast Cancer Research Co-Director, Molecular Signaling Program, Louisiana Cancer Research Consortium Director, Tulane Circadian Biology Center Medical Research: What are the main findings of the study? Dr. Hill: The main findings of our study are that exposure to even dim light at night can drive human breast tumors to a hyper metabolic state, activating key tumor cell signaling pathways involved in tumor cell survival and proliferation, leading to increased tumor growth, all resulting in a tumor which is completely resistant to therapy. Our work shows that this effect is due to the repression of nighttime melatonin by dim light at night. When nighttime melatonin is replace the tumors become sensitive to tamoxifen resulting in cell death and tumor regression. (more…)

Dr. Hsich: Women are dying on the heart transplant waiting list at a faster rate than men for almost a decade (see Figure 1) and few studies have even addressed this problem. The occurrence is largely driven by gender differences in survival at the most urgent status (UNOS Status 1A) but the cause remains unclear. Although data is limited our findings raise concern that women are not successfully bridged to transplantation while they remain at high status and are inactivated due to worsening condition.

Dr. Bryan K. Woodruff Assistant Professor of Neurology Mayo Clinic, ArizonaMedicalResearch.com Interview Invitation Dr. Bryan K. Woodruff Assistant Professor of Neurology Mayo Clinic, Arizona Medical Research: What are the main findings of the study? Dr. Woodruff: There is evidence in the medical literature supporting a negative impact of losing a spouse for health conditions such as cancer or cardiovascular disease, but this has not been evaluated in terms of the impact of widowhood on the development of dementia.  We used the National Alzheimer’s Disease Coordinating Center (NACC) database, which pools data gathered by multiple federally-funded Alzheimer’s disease research centers to try to answer this question.  Specifically, we looked at the age at which individuals ultimately developed dementia in both individuals who lost their spouse and in those who remained married over the course of the study.  Surprisingly, the data we analyzed did not support a negative impact of losing a spouse in individuals who had no cognitive difficulties when they entered the study, and we saw a paradoxical effect of widowhood in those with mild cognitive impairment (MCI).

Fiellin, M.D. Associate Professor of Medicine Director, play2PREVENT Lab Yale University School of Medicine New Haven, CT 06510 Medical Research: What are the main findings of the study? Dr. Fiellin: The current findings are part of a larger study evaluating an interactive evidence-based video game, PlayForward: Elm City Stories, developed on the iPad and targeting risk reduction and HIV prevention in 333 young teens (ages 11-14). The larger study is examining a range of outcomes including knowledge, intentions, self-efficacy and actual behaviors and we are collecting at baseline, 6 weeks, 3, 6, 12, and 24 months. We are examining these outcomes in our experimental group compared with a control group playing a set of off-the-shelf games on the iPad. The current findings of the 196 teens who have completed the 6 weeks of gameplay and for whom we have baseline and 3 month data, reveal that, while the two groups had no differences in their baseline HIV risk knowledge, the PlayForward group had statistically significant gains in knowledge at 6 weeks (p<0.0001), sustained at 3 months (p<0.01). In addition, examining the association between exposure to the game and performance on the standardized assessments revealed that the number of game levels completed (a measure of exposure to the intervention) was positively correlated with knowledge gains measured at 3 months (r=0.42; p<0.001).

Dr. Dan Everitt Senior Medical Officer, TB Alliance.MedicalResearch.com Interview with: Dr. Dan Everitt Senior Medical Officer, TB Alliance. Medical Research: What are the main findings of the study? Dr. Everitt: The NC-002 trial tested a new, three-drug TB combination therapy, consisting of PA-824 (a new chemical entity), moxifloxacin (a re-purposed drug, not yet approved for TB treatment), and pyrazinamide (an existing TB drug currently used in standard TB treatment). This regimen is known as "PaMZ" and was tested in both drug-sensitive and multidrug-resistant TB (MDR-TB patients). In the eight-week trial, PaMZ killed more bacteria than standard therapy and did so at a faster rate, showing its potential to shorten therapy to as little as four months for drug-sensitive and some forms of MDR-TB. Additionally, the trial included HIV-positive patients and a formal statistical evaluation found no effect of HIV status on the outcome of the study. (more…)

Answer: Our study sought to characterize how many clinically important issues that occur during the overnight on-call period were handed over and discussed by the on-call resident with the daytime medical team. For example, if a patient developed chest pain in the middle of the night and the on-call resident evaluated the patient, did the resident then 'handover' this issue to the team the next morning so that they could follow up and make sure that the patient receives timely care? In our study, we found that approximately 40% of these issues did not get handed over. This finding was consistent across 2 major Canadian academic teaching hospitals. (more…)

Aakriti Gupta, MD, MBBS Center for Outcomes Research and Evaluation Yale-New Haven Hospital, New Haven, ConnecticutMedicalResearch.com Interview with: Aakriti Gupta, MD, MBBS Center for Outcomes Research and Evaluation Yale-New Haven Hospital, New Haven, Connecticut Medical Research: What were the main findings? Dr. Gupta: Using a national database, we found that heart attack hospitalization rates for patients under the age of 55 have not declined in the past decade while their Medicare-age counterparts have seen a 20 percent drop. We also found that among younger patients below 55 years of age, women fare worse because they have longer hospital stays, and are more likely to die in the hospital after a heart attack. Young women were also more likely to have higher prevalence of co-existing medical conditions including diabetes, high blood pressure and higher cholesterol levels. Overall, all patient groups in the study saw increases in these conditions including diabetes and high blood pressure in the past decade. (more…)

Dr. Nelli Westercamp PhD, MPH, MBA University of Illinois at Chicago School of Public Health Kenya, Epidemiology and Public HealthMedicalResearch.com Interview with: Dr. Nelli Westercamp PhD, MPH, MBA University of Illinois at Chicago School of Public Health Kenya, Epidemiology and Public Health Medical Research: What are the main findings of the study? Dr. Westercamp: The three clinical control trials in Kenya, Uganda and South Africa found that male circumcision reduces the risk of female to male transmission by up to 60%, prompting the endorsement of medical male circumcision as an HIV prevention intervention by the WHO and UNAIDS.  However, as medical male circumcision services for HIV prevention are being rolled out in the priority countries, questions remain whether the male circumcision promotion will actually translate into decreases in HIV infections. One factor that could reduce the effectiveness of male circumcision for HIV prevention at the population level is the behavioral risk compensation.  In other words, if men who become circumcised believe that they are fully protected against HIV and engage in higher sexual risk taking behaviors as a result of this belief, this could reduce or even negate the protective effect of male circumcision against HIV. To answer this question, we conducted a large prospective study concurrently with the scale up of male circumcision services in Western Kenya.  We recruited 1,588 men seeking circumcision services as well as 1,598 men who decided to remain uncircumcised  and assessed their sexual behaviors over 2 years, every 6 months.  We then compared the behaviors of circumcised men before and after circumcision and also the behaviors of circumcised and uncircumcised men over time. In the beginning of the study, we found that men choosing to become circumcised believed they were at higher risk of HIV than their uncircumcised counterparts. This perception of HIV risk declined significantly among the circumcised men after circumcision (from 30% at baseline to 14% at 24 months of follow up), while remaining relatively stable among the uncircumcised men (24% to 21%, respectively).  Looking at sexual risk behaviors, we saw that the overall level of sexual activity increased equally in both groups, mostly driven by the youngest age group (18-24 year old). However, despite the decrease in risk perception among circumcised men and the increase in sexual activity among all men, all other risky behaviors decreased in both groups and protective behaviors – such as condom use – increased, particularly among circumcised men.

Riyaz Bashir MD, FACC, RVT Associate Professor of Medicine Director, Vascular and Endovascular Medicine Department of Medicine Division of Cardiovascular Diseases Temple University Hospital Philadelphia, PA 19140MedicalResearch.com Interview with Riyaz Bashir MD, FACC, RVT Associate Professor of Medicine Director, Vascular and Endovascular Medicine Department of Medicine, Division of Cardiovascular Diseases Temple University Hospital Philadelphia, PA 19140 Medical Research: What is the background for this study? Dr. Bashir : Blood clots of legs called deep vein thrombosis (DVT) is a very common disease that occurs in about 1.0 person per 1000 population per year. This condition is responsible for more than 600,000 hospitalizations each year in the United States and approximately 6% of these patients will die within 1 month of the diagnosis. Amongst these patients 20% - to 50% will go on to develop chronic leg pains, swelling, heaviness, skin discoloration, and ulcers, in spite of conventional treatment with Blood thinning medications (anticoagulation) and compression stockings.This condition, which is called Post-thrombotic syndrome PTS markedly impairs the quality of life of these patients and is a significant economic burden (2.4 billion dollars and 200 million work days lost annually in US) on the society.In fact, many of these people lose their jobs because of the disability it causes. Several small studies have shown that early clot removal by minimally invasive catheter-based clot busting procedure called Catheter-directed thrombolysis (CDT) leads to a significant reduction in Post-thrombotic syndrome along with improvements in quality of life. Unfortunately, due to the small number of patients in these studies, we did not have any data about the safety of this treatment option. This has led to conflicting recommendations by various medical societies like the American College of Chest Physicians recommending against its use while the American Heart Association recommends Catheter-directed thrombolysis as first-line treatment for these patients. In light of these conflicting directives, we reviewed the frequency and safety of CDT versus conventional treatment in these patients with blood clots above the knees in the United States using Nationwide Inpatient Sample database from 2005 to 2010.
