MedicalResearch.com Interview with Dr. Richard Haynes Clinical Trial Service Unit and Epidemiological Studies Unit Roosevelt Drive, Headington Oxford OX3 Medical Research: What are the main findings of the study? Dr. Haynes: The main result from this analysis is that alemtuzumab-based induction therapy (ie, alemtuzumab followed by low-dose mycophenolate and tacrolimus with steroid avoidance) reduced biopsy-proven acute rejection by about half during the first 6 months after transplantation among a wide variety of different types of participant, compared to standard basiliximab-based induction therapy (basiliximab followed by standard dose mycophenolate, tacrolimus and steroids). This reduction was achieved despite the lower doses of tacrolimus used and there was no excess of infection observed. (more…)

Wendy Macias Konstantopoulos, MD, MPH Department of Emergency Medicine Division of Global Health & Human Rights Massachusetts General Hospital Harvard Medical SchoolMedicalResearch.com Interview with: Wendy Macias Konstantopoulos, MD, MPH Department of Emergency Medicine Division of Global Health & Human Rights Massachusetts General Hospital Harvard Medical School Medical Research: What are the main findings of the study? Dr. Macias-Konstantopoulos: Nearly two-thirds (64%) of 3240 emergency department (ED) patients who endorsed using drugs in the last 30 days, met criteria for problematic drug use (DAST-10 score ≥3). Of patients who identified their primary drug of use as being a substance other than cannabis, approximately 91% met criteria for problematic drug use, including nearly 94% of those using illicit drugs and 76% of those using pharmaceuticals. Compared to those who used cannabis primarily, primary non-cannabis users had an almost 15 times higher odds of meeting criteria for problematic drug use. Finally, we know from previous studies that drug-using individuals are more likely to access medical care through the ED and more likely to require hospitalization than their non-drug using counterparts. Our study found that drug-using ED patients who met criteria for problematic drug use tended to have ED triage levels associated with higher levels of severity or resource utilization when compared to drug-using ED patients who did not meet criteria for a drug problem.

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.

Sean Davies PhD Department of Pharmacology Vanderbilt UniversityMedicalResearch.com Interview with: Sean Davies PhD Department of Pharmacology Vanderbilt University Medical Research: What are the main findings of the study? Dr. Davies: N-acyl phosphatidylethanolamine (NAPE) is a fat-like molecule normally produced by small intestine of mammals in response to eating high fat foods that helps signal a feeling of fullness to the brain.  This sensation of fullness is what normally helps us decide to stop eating, but in obese people it appears that not enough NAPE is produced so that not enough of that signal gets sent to the brain.  So we wanted to find a way to increase the amount of NAPE made in the intestinal tract, with the hope that this would help protect against obesity. Our approach was to engineer a probiotic bacteria that normally colonizes the gut of humans and other mammals so that it would make NAPE.  Our hope was that when this gut bacteria made the NAPE, it would be absorbed by the intestine and help supplement the NAPE already being made by the intestine so that a more complete sensation of fullness would be send to the brain. What we found was that our engineered bacteria made a significant amount of NAPE and that when fed to mice, the bacteria would colonize the gut like normal and that the intestinal cells could absorb this NAPE.  Most importantly, we found that mice that received this bacteria ate less of the high fat diet than mice that were not treated or that received bacteria that did not make NAPE. Because the mice ate less of the high fat diet, and also because they burned the fat they had more effectively, the mice receiving the bacteria producing NAPE had only 50% of  the body fat of the control mice.  While the control mice showed the early signs of developing diabetes, the mice that received the NAPE producing bacteria showed almost no signs of developing diabetes. So the presence of these NAPE producing bacteria protected the mice from the harmful effects of the high fat diet. Another key findings was that because the bacteria live in the GI tract and keep producing the NAPE for many weeks, we didn’t have to keep administering the bacteria to the mice to keep up the protective effect.  Even a month after we stopped giving the bacteria producing NAPE, the mice were still protected from the effects of the high fat diet.  Eventually after about six weeks, the bacteria died out and the mice started eating the same amount of food as the control mice, but even for at least another six weeks after this, they still weighed less than the control mice.

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…)
