Amy Nunn, ScD, MS Assistant professor (research) of Behavioral and Social Sciences Brown University School of Public HealthMedicalResearch.com Interview with: Amy Nunn, ScD, MS Assistant professor (research) of Behavioral and Social Sciences Brown University School of Public Health MedicalResearch.com: What are the main findings of the study? Answer: The main findings are that people living in poor, mostly-minority urban neighborhoods, where health resources such as HIV testing and linkages to care are often lacking, are at a greater risk of contracting HIV and dying of AIDS. This is not because of differences in behavior. It's because they live in medically underserved areas where HIV incidence is very high and fewer people know their status. Fewer people knowing their status means fewer people on treatment. Fewer people on treatment means it's easier for people to come into contact with the virus, even if they don't engage in any higher risk behavior. In the paper, my colleagues and I call for increasing the focus of public health efforts on these neighborhoods where the epidemic is concentrated and contributing heavily to racial and economic disparities in AIDS mortality.

Pfeffer, M.D., Ph.D. Dzau Professor of Medicine Harvard Medical School Cardiovascular Division Brigham and Women's Hospital MedicalResearch.com: What are the main findings of the study? Dr. Pfeffer: We randomized 3445 patients with symptomatic heart failure and a left ventricular ejection fraction greater than or equal to 45% (heart failure with preserved ejection fraction or diastolic heart failure) to spironolactone or placebo and followed them for over 3 years. Our primary outcome the composite of death from cardiovascular causes, aborted cardiac arrest, or hospitalization for management of heart failure was not significantly reduced in the group randomized to spironolactone. We did, however, observe that fewer patients in the spironolactone group were hospitalized for the management of heart failure following randomization. Spironolactone therapy was associated with higher incidence of  hyperkalemia and rises in serum creatinine. (more…)

dr_sabina-sieriMedicalResearch.com Interview with: Sabina Sieri, PhD Epidemiology and Prevention Unit Department of Preventive & Predictive Medicine Fondazione IRCCS Istituto Nazionale dei Tumori 20133 Milan – Italy MedicalResearch.com: What are the main findings of this study? Dr. Sieri: In our study we found that there was an increased risk of developing breast cancer from high saturated fat intake. High total and saturated fat intake were associated with greater risk of ER PR positive breast cancer. High saturated fat intake was also associated with a greater risk of HER2 negative disease. So, a high-fat diet increases breast cancer risk and, most conspicuously, a high saturated fat intake increases the risk of developing hormone-sensitive diseases, suggesting saturated fat involvement in the etiology of hormone-sensitive breast cancer.

Piotr Lewczuk Head,Lab for Clinical Neurochemistry and Neurochemical Dementia Diagnostics, Universitätsklinikum Erlangen, Department of Psychiatry and Psychotherapy, 91054 Erlangen, Germany MedicalResearch.com: What are the main findings of the study? Prof. Dr. med. Piotr Lewczuk: In our study, we investigated the concentrations of four isoforms of amyloid beta peptides in the blood of healthy young volunteers without memory complains. The participants were stratified into three groups according to their apolipoprotein E (APOE) genotype, which is the mostly investigated and generally accepted genetic risk factor for sporadic Alzheimer’s Disease (AD). It is known that the alterations of the amyloid beta metabolism are the earliest changes in the course of AD, occurring many years (or even decades) before the onset of the clinical symptoms, but it is actually not known how early these alterations start. Correspondingly, we wanted to investigate if healthy persons with genetic risk factor show changes in their amyloid beta metabolism already 30-40 years before the age when AD is usually diagnosed. We did not find any differences between the groups with and without APOE-driven risk, which might be carefully interpreted as no signs of Alzheimer’s Disease pathology in persons at risk at such an early life stage. Taken together, we think that the Alzheimer’s Disease pathology starts some 10-20 years before the beginning of the clinical symptoms, but not earlier. (more…)

Dr. Judy C. Boughey MD Professor of Surgery Mayo Clinic, Rochester MNMedicalResearch.com Interview with Dr. Judy C. Boughey MD Professor of Surgery Mayo Clinic, Rochester MN MedicalResearch.com: What are the main findings of the study?   Dr. Boughey: This study showed that the rate of reoperation after lumpectomy for breast cancer was significantly lower at Mayo Clinic in Rochester compared to national data. Mayo Clinic in Rochester uses frozen section analysis of margins at time of lumpectomy to direct any margin re-excisions during the surgery and therefore has a significantly lower rate of need for a second operation to ensure clean margins. The rate of reoperation was four times higher in the national data set than in the Mayo Clinic data set.

MedicalResearch.com Interview witih: Dr. Constance Tom Noguchi, Ph.D. Molecular Medicine Branch National Institute of Diabetes and Digestive and Kidney Diseases, National Institutes of Health, Bethesda, MD 20892  and Dr. Mawadda Al-Naeeli Department of Biological Sciences, Ohio University MedicalResearch.com: What are the main findings of the study? Answer: The main findings of our study are: 1) EPO treatment has an anti-inflammatory effect on white adipose tissue macrophage population during diet-induced obesity in addition to its associated metabolic improvements on glucose tolerance and insulin sensitivity in vivo. 2) In this model of obesity, EPO treatment was found to reduce M1-like [pro-inflammatory] and increased M2-like [anti-inflammatory] macrophages in visceral white adipose tissue depot. 3) In addition, EPO decreased circulating inflammatory monocytes. 4) These anti-inflammatory effects of EPO were found to be driven, at least in part, by direct EPO-R response in macrophages via Stat3 activation, where EPO effects on M2 but not M1 macrophages required interleukin-4 receptor/Stat6 axis. 5) The anti-inflammatory effects of EPO are not restricted to treatment with exogenous high dose EPO (1000U/kg), but also include endogenous physiological EPO levels as demonstrated by the series of studies conducted using ΔEpoR mice with EPO-R restricted to erythroid cells.

Bradley S. Peterson, MD Director of the Center for Developmental Neuropsychiatry Director of the Center for Developmental Neuropsychiatry, New York State Psychiatric Institute Suzanne Crosby Murphy Professor in Pediatric Neuropsychiatry, Columbia University, NYMedicalResearch.com Interview with: Bradley S. Peterson, MD Director of the Center for Developmental Neuropsychiatry Director of the Center for Developmental Neuropsychiatry, New York State Psychiatric Institute Suzanne Crosby Murphy Professor in Pediatric Neuropsychiatry, Columbia University, NY MedicalResearch.com: What are the main findings of the study? Dr. Peterson: We detected the presence of lactate in the brains of 13% of 75 participants who had ASD (Autism Spectrum Disorder), compared with 1% of the brains of 96 typically developing control participants. The presence of lactate was especially more common in adults who have ASD. Lactate is a product of anaerobic metabolism, which generally should not occur in healthy, living brains under normal circumstances. The presence of lactate in the brains of persons with Autism Spectrum Disorder therefore suggests the presence of deficient production of energy stores by a component of brain cells called “mitochondria”. We detected lactate most commonly in the cingulate gyrus, a region that supports the higher-order control of thought, emotion, and behavior, and that has been implicated previously in Autism Spectrum Disorder.

Schisterman, Ph.D. Chief and Senior Investigator Epidemiology Branch, DIPHR Eunice Kennedy Shriver National Institute of Child Health and Human Development Rockville, MD 20854 MedicalResearch.com: What are the main findings of the study? Dr. Schisterman: Our results indicate that aspirin is not effective for reducing the chances of pregnancy loss in most cases. For the total number of women in the study, 13 percent of women who took aspirin and became pregnant subsequently experienced another loss, compared with 12 percent who took the placebo. Ultimately, 58 percent of women taking aspirin and 53 percent of the placebo group got pregnant and later gave birth. However, additional research is needed to investigate the finding that women who had experienced a single, recent pregnancy loss (before 4 1/2 months of pregnancy and within the past year) had an increased rate of pregnancy and live birth while on aspirin therapy. Among this group, 78 percent of those who took aspirin became pregnant, compared with 66 percent of those who took the placebo. For this subset of women, 62 percent of the aspirin group and 53 percent of the placebo group gave birth. (more…)

Ulla Räisänen Senior Researcher HERG Health Experiences Research Group Department of Primary Care Health Sciences University of Oxford Oxford OX1 2ETMedicalResearch.com  Interview with Ulla Räisänen Senior Researcher HERG Health Experiences Research Group Department of Primary Care Health Sciences University of Oxford Oxford OX1 2ET MedicalResearch.com : What are the main findings of the study? Answer: We conducted a qualitative interview study exploring how young men (aged 16-25) recognise eating disorder symptoms and decide to seek help, and to examine their experiences of initial contacts with primary care in the UK. Our data suggest that the widespread perception of eating disorders as uniquely or predominantly a female problem led to an initial failure by young men to recognise their behaviours as symptoms of an eating disorder. Many presented late in their illness trajectory when eating disorder behaviours and symptoms were entrenched, and some felt that opportunities to recognise their illness had been missed because of others’ lack of awareness of eating disorders in men. In addition, the men discussed the lack of gender-appropriate information and resources for men with eating disorders as an additional impediment to making sense of their experiences, and some felt that health and other professionals had been slow to recognise their symptoms because they were men.

Answer: We analyzed data from a nationally representative survey on youth risk behaviors. After adjusting for other risk taking behaviors, we found that high school adolescents who indoor tan were much more likely to also engage in behaviors typically associated with eating disorders. We also noted that the link between indoor tanning and such harmful weight control behaviors was even stronger among males than females. (more…)

Dr. Gao: In this study including 12,556 men in the Health Professionals Follow-up Study, we found that the participants with Restless Legs Syndrome at baseline had significantly lower physical function (PF) score 6 years later than those without RLS, after adjusting for potential confounders. The magnitude of difference in physical function score for RLS symptoms ≥15 times/month vs no Restless Legs Syndrome was more than that of a 5-year increase of age or moderate amount of smoking. We also found that having daily daytime sleepiness and sleep duration ≥9 hours/day were associated with lower mean physical function value than not having these symptoms . (more…)

Müller University of Bonn Pharmaceutical Institute Pharmaceutical Chemistry I An der Immenburg 4  D-53121 Bonn (Endenich) Germany MedicalResearch.com: What are the main findings of the study? Prof. Dr. Christa E. Müller: Genetically altered mice which show an aggregation of Tau protein and many symptoms of Alzheimer's Disease which progressively worsen with time was used. Caffeine was given to one group of mice at an early stage, when the symptoms were still moderate. The caffeine-treated mice showed better memory and less inflammation and brain damages in comparison to the non-treated control mice. This means that caffeine protected the mice to some extent. The side effects were moderate. (more…)

Dr. Ouimet :The goal of our study was to examine if teenagers’ driving risk was associated with a neurobiological factor. Driving was continuously observed with cameras and sensors installed in the vehicles of teenagers during their first 18 months of licensure. Cortisol response was measured within the first weeks of licensing. Our study showed two main findings: 1) Higher cortisol response to a stressful event was associated with lower crash and near crash rates over the study period; 2) Higher cortisol response was also linked to a sharper decrease in crash and near crash rates over time.   (more…)

MedicalResearch.com Interview with: dr_Aalex_d_leowAlex Leow, MD PhD Psychiatric Institute Chicago, IL 60612 and   Tony J. Simon, PhD University of California, Davis MIND Institute Sacramento, CA 95817Tony J. Simon, PhD University of California, Davis MIND Institute Sacramento, CA 95817 MedicalResearch.com: What are the main findings of the study? Answer: Fragile X syndrome (FXS) is the most common inherited cause of intellectual disabilities and the most prevalent known single-gene cause of autism in males. The fragile X mental retardation 1 gene (FMR1) can be mutated with expanded numbers of CGG trinucleotide repeats in the 5’ untranslated region on the Xq27.3 site of the X chromosome. Normally, unaffected individuals have fewer than 45 CGG repeats in FMR1. When the size of the CGG repeat exceeds 200 FMR1 is silenced and the mutation is categorized as full, generating the FXS phenotype. If the expansion is between 55–200 repeats, then the individual is generally classified as a fragile X premutation carrier (fXPC). An estimated 40% of male and 8-16% of female premutation carriers later develop Fragile X-Associated Tremor/Ataxia Syndrome (FXTAS), which is a late-onset (usually 50-70 years old) neurodegenerative disorder. We recruited 46 neurologically symptomless young to middle aged carriers of the FMR1 gene mutation. They were age and gender matched with 42 unaffected control individuals without the gene mutation. Both groups were evaluated by cognitive testing as well as novel neuroimaging techniques termed “brain connectomics,” based on diffusion tensor imaging (DTI) whole-brain tractography.  A connectome is a comprehensive map, like a wiring diagram, of neural connections in the brain. Our study is the first-ever connectome study to compare fXPCs and controls. In short, brain connectomics enable scientists for the first time to study the global organizational properties of the human brain by applying cutting edge computational techniques, based on graph theory, to these comprehensive maps of neural connections (i.e., the brain graphs). Our main finding was that, in neurologically symptomless male carriers  we detected a correlation between brain graphs’ efficiency in processing information and the number of CGG repeats in the mutated region of FMR1 (we estimated that each additional CGG repeat that in these males represents an effective increase of ~1.5 years  of “brain aging”). The correlation may prove to be an effective marker of early brain aging in otherwise neurologically symptomless premutation carriers. The study also further confirmed previous findings of smaller brain stem volumes in male fXPCS than in male controls. (more…)

Dr. Ivo Lieberam Lecturer, MRC Centre for Developmental Neurobiology King's College London New Hunt's House, Guy's Hospital Campus London, SE1 1UL UKMedicalResearch.com Interview with: Dr. Ivo Lieberam Lecturer, MRC Centre for Developmental Neurobiology King's College London New Hunt's House, Guy's Hospital Campus London, SE1 1UL UK  MedicalResearch.com: What are the main findings of the study? Dr. Lieberam: In this study, which my group undertook in collaboration with Linda Greensmith’s group at University College London, we found that we could artificially control muscle activity using transplanted stem cell-derived nerve cells as an interface between an opto-electronic pacemaker and paralysed muscle in mice. The nerve cells were equipped with a molecular photosensor, so that they could be activated by light. We think that long-term, this technology may be used in neural prosthesis designed to re-establish relatively simple motor functions, such as breathing or swallowing, in patients suffering from spinal cord injury or neuromuscular diseases such as Motor Neuron Disease.

David R. Jacobs Jr, PhD Divisions of Epidemiology School of Public Health University of Minnesota, MinneapolisMedicalResearch.com Interview with: David R. Jacobs Jr, PhD Divisions of Epidemiology School of Public Health University of Minnesota, Minneapolis MedicalResearch.com: What are the main findings of this study? Dr. Jacobs: Vigorous activity is what is well understood to improve cardiorespiratory fitness. People with high fitness are likely (based on this study) to a) Lose fitness more slowly as they age and b) To maintain sharper "thinking skills" into late middle age. I think the message of this study is primarily for the people in the low to mid range of fitness in young adulthood.  Thus, of more importance to the general population, if the people with low to moderate fitness simply do things, be engaged in family, job, community, move around, they would  be able to do better on a treadmill test such as we used.  Because those who lost less fitness over average age 25 to average age 45 had higher thinking skills at age 50, people who start moving around are likely to reap the benefit of less loss of thinking skills by average age 50.

Massimo Porta, MD PhD Professor of Medicine Head, Unit of Internal Medicine 1 Department of Medical Sciences  University of TurinMedicalResearch.com Interview with: Massimo Porta, MD PhD Professor of Medicine Head, Unit of Internal Medicine 1 Department of Medical Sciences  University of Turin MedicalResearch.com: What are the main findings of the study? Dr. Porta: Type 2 diabetes has a slow, insidious onset and may remain undiagnosed for several years, during which complications may arise and progress. As a result, many patients already have retinopathy at the time a clinical diagnosis is finally made. Previous attempts at estimating the duration of this period of "hidden" diabetes relied upon  extrapolations of a linear correlation between known duration of diabetes and prevalence of retinopathy. This led to overestimates, because: a) the best fitting correlation may not be linear, b) series included insulin treated patients, who might have late-onset type 1 diabetes, c) patients with any mild retinopathy were included whereas we now know that up to 10% of non diabetic individuals may have minimal retinal signs. By taking these variables into account, ie including only patients not on insulin and with moderate or more severe retinopathy and applying different mathematical models, we ended up with an estimated duration preceding diagnosis of type 2 diabetes of 4-6 years, against longer than 13 years using "standard" criteria.
