MedicalResearch.com Interview with Dr. Brian Haas MD Department of Diagnostic Radiology,Yale University School of Medicine, New Haven, CT Dr. Brian Haas MD Department of Diagnostic Radiology,Yale University School of Medicine, New Haven, CT MedicalResearch.com: What are the main findings of the study? Dr. Haas: We found that tomosynthesis helped to reduce the number of women who undergo a screening mammogram and are called back for additional imaging and testing. Specifically, the greatest reductions in patients being called back were seen in younger patients and those with dense breasts. Tomosynthesis is analogous to a 3D mammogram, and improves contrast of cancers against the background breast parenchyma. (more…)

Answer: The study shows that people who live at locations with higher levels of particles in the air are at higher risk for development of lung cancer. It seems that there is no threshold for air pollution with particles below which there is no risk; the results show that it is more like “the more air pollution the worse and the less pollution the better”. The strongest association was seen for adenocarcinoma of the lung. (more…)

MedicalResearch.com Interview with: Dr. Henna Cederberg MD PhD, Postdoctoral Fellow University of Eastern Finland and Kuopio University Hospital Department of Medicine 70210 Kuopio, Finland MedicalResearch.com:  What are the main findings of the study? Dr. Cederberg: The association of risk variants previously identified for type 2 diabetes and hyperglycemia with gestational diabetes were evaluated in 533 Finnish women with gestational diabetes and 407 controls. The main finding of the study was that gestational diabetes and type 2 diabetes share a similar genetic background. Two risk variants of MTNR1B were significantly associated with gestional diabetes. Our study suggests that risk variants of MTNR1B are associated with gestational diabetes by increasing fasting glucose and decreasing insulin secretion.  In addition, another six single nucleotide polymorphisms associated with type 2 diabetes and hyperglycemia were nominally associated with gestational diabetes.

Davis, M.D., Endowed Chair of Neurology Professor Departments of Neurological Sciences, Biochemistry and Pharmacology Rush University Medical Center 1735 West Harrison St, Suite 320 Chicago, IL 60612MedicalResearch.com Interview with: Kalipada Pahan, Ph.D. The Floyd A. Davis, M.D., Endowed Chair of Neurology Professor Departments of Neurological Sciences, Biochemistry and Pharmacology Rush University Medical Center 1735 West Harrison St, Suite 320 Chicago, IL 60612 MedicalResearch.com: What are the main findings of the study? Dr. Pahan: While different toxins and a number of complex genetic approaches are used to model Parkinson’s disease in mice, this study delineates that simple castration is sufficient to cause persistent Parkinson’s like pathology and symptoms in male mice. This simple, but persistent, model may be helpful in discovering drugs against Parkinson’s disease. Furthermore, these results suggest that sudden drop of testosterone level could trigger Parkinson’s disease. (more…)

Dr. Pietro Manuel Ferraro Division of Nephrology–Renal Program, Department of Internal Medicine and Medical Specialties, Columbus-Gemelli Hospital, Rome, ItalyMedicalResearch.com Interview with Dr. Pietro Manuel Ferraro Division of Nephrology–Renal Program, Department of Internal Medicine and Medical Specialties, Columbus-Gemelli Hospital, Rome, Italy MedicalResearch.com: What are the main findings of the study? Dr. Ferraro: We analyzed three large cohorts over time to see if those with prevalent or incident kidney stones might have a higher risk of developing coronary heart disease (fatal or non fatal myocardial infarction or the need for coronary revascularization). The cohorts consisted of over 200,000 participants without any prior history of coronary heart disease. After a median follow-up of over 8 years, we observed that women affected with stones seem to have a greater risk of developing coronary heart disease independent of a number of other known cardiovascular risk factors such as diabetes or high blood pressure. We did not observe a significant association among men. (more…)

MedicalResearch.com Interview with: Michelle N. McDonnell, PhD Division of Health Sciences International Centre for Allied Health Evidence University of South Australia Adelaide, SA 5001 Australia.Michelle N. McDonnell, PhD Division of Health Sciences International Centre for Allied Health Evidence University of South Australia Adelaide, SA 5001 Australia. MedicalResearch.com: What are the main findings of the study? Dr. McDonnell: In this study, we asked people how many times a week they engaged in intense physical activity, enough to work up a sweat. People responded that they were physically active 0, 1-3 or 4 or more times a week. When we followed up these people for several years, those who did not do any vigorous exercise were 20% more likely to have a stroke, compared to those who exercised four or more times a week. However, when we adjusted these results for other risk factors, this attenuated the effect down to 14%  which was not statistically significant. We also noticed that people who exercised four or more times a week had less hypertension (high blood pressure), were less likely to be obese and less likely to have diabetes. Each of these things on their own reduces your risk of stroke, so when we adjust for that the association between physical activity and stroke is weaker (20% to 14%). So physical activity seems to have an effect on stroke risk by improving these other risk factors. (more…)

MedicalResearch.com Interview with: Xiaolu Yang, Ph.D.MedicalResearch.com Interview with: Xiaolu Yang, Ph.D. Professor of Cancer Biology at the Perelman School of Medicine University of Pennsylvania and the Abramson Family Cancer Research Institute, MedicalResearch.com: What are the main findings of the study? Dr. Yang: TAp73 is a structural homologue of the preeminent tumor suppressor p53, but its role in tumorigenesis has been unclear. In this study, we show that TAp73 supports the proliferation of tumor cells. Mechanistically, TAp73 activates the expression of glucose-6-phosphate dehydrogenase (G6PD), a rate-limiting enzyme in the pentose phosphate pathway. This function of TAp73 is required for maintaining a robust biosynthesis and anti-oxidant defense in tumor cells. These finding connects TAp73 to oncogenic growth and suggest that G6PD may be a valuable target for tumor therapy. (more…)
Author Interviews, Coffee, Nutrition, Orthopedics, Osteoporosis / 25.07.2013

Helena Hallström Uppsala University, Disciplinary Domain of Medicine and Pharmacy, Faculty of Medicine, Department of Surgical Sciences, OrthopaedicsMedicalResearch.com Interview with: Helena Hallström Ph.D., M.Sc. (Toxicology) Department of Surgical Sciences, Section of Orthopedics Uppsala University, Uppsala, Sweden and Risk and Benefit Assessment Department National Food Agency, Uppsala, Sweden.   MedicalResearch.com: What are the main findings of the study? Answer: The aim of the study was to investigate whether high consumption of coffee is associated with osteoporosis and development of osteoporotic fractures, since results from previous fracture studies regarding potential associations between coffee drinking and fracture risk are inconsistent. The longitudinal population-based Swedish Mammography Cohort, including 61,433 women born between 1914 and 1948, was followed from 1987 through 2008. Coffee consumption was assessed with repeated food frequency questionnaires. During follow-up, 14,738 women experienced any type of fracture and of these 3,871 had a hip fracture. In a sub-cohort (n=5,022), bone density was measured and osteoporosis was determined (n=1,012). There was no evidence of a higher rate of any fracture or hip fracture with increasing coffee consumption. However, a high coffee intake (≥4 cups) in comparison with a low intake (<1 cup) was associated with a 2-4% reduction in bone mineral density (BMD), depending on site (p<0.001), but the odds ratio of osteoporosis was only 1.28 (95% confidence interval: 0.88, 1.87). Thus, high coffee consumption was associated with a small reduction in bone density that did not translate into an increased risk of fracture. (more…)

MedicalResearch.com Interview with: Lillian S. Kao, MD, MS Associate Professor, Department of Surgery The University of Texas School of Medicine at Houston Houston, Texas 77030 MedicalResearch.com: What are the main findings of the study? Dr. Kao: -The internal validity (methodological rigor) and external validity (generalizability) of quality improvement (QI) studies of implementation of surgical antibiotic prophylaxis measures are poor. -Studies demonstrating large positive effect on compliance were often performed in settings where the baseline compliance was extremely low (i.e., less than 20%), thus further limiting their generalizability. -Very few studies evaluated the effect of the QI interventions to increase appropriate antibiotic prophylaxis use on surgical site infections (SSIs). Moreover, those studies that included SSI as an outcome measures were usually underpowered to identify a significant effect. -The majority of studies failed to report metrics relating to the quality of the implementation of the interventions to increase antibiotic prophylaxis compliance. Effectiveness of evidence-based measures is dependent upon their implementation. For example, did all of the targeted groups adopt the intervention? Or were the QI interventions sustained beyond the initial measurement or study period? (more…)

Pshezhetsky, Ph.D. Professor Departments of Pediatrics and Biochemistry University of Montreal Division of Medical Genetics Sainte-Justine University Hospital Research Center Montréal, PQ, Canada, H3T 1C5. MedicalResearch.com: What are the main findings of the study? Dr. Pshezhetsky: Our laboratory found that the presence of sugar known as sialic acid on the insulin receptor can determine whether cells react normally to insulin or are resistant. Sialic acid modifies molecules like the insulin receptor, and reduces their activity.   We studied the enzyme that removes sialic acid, known as neuraminidase 1 or Neu1.  Cells that lacked Neu1 had more sialic acid on the insulin receptor and were resistant to insulin.  Genetically-modified mice with ~10% of the normal Neu1 activity exposed to a high-fat diet develop hyperglycemia and insulin resistance twice as fast as their wild type counterparts.  Together, these studies identify Neu1 and sialic acid as novel components of the signaling pathways of energy metabolism and glucose uptake.

Prof. Zajicek: Our study investigated whether dronabinol (one of the major active ingredients of cannabis) may slow the progression of multiple sclerosis. We currently have no treatments that are effective in modifying the disease course in people with either primary or secondary MS. We did a clinical trial across the UK involving nearly 500 patients, who were randomly allocated to dronabinol or placebo, and followed them up for three years to look at progression on rates. Overall we failed to find an effect of dronabinol on disease progression,  either clinically (using a variety of clinical measures) or using magnetic resonance imaging (MRI). There was a suggestion of an effect in people with the least disability (who didn't need a stick to help them walk), and there were no major problems with serious side effects.  However, over all the population that took part in the study also progressed less than we expected, which reduced our chances of finding an effect of treatment. The  study was not designed to investigate an effect on MS-related symptoms (such as pain and muscle stiffness), which have been investigated before. (more…)

MedicalResearch.com Interview with: Abigail Franklin Vice President for Development & Communications The New York Academy of Medicine MedicalResearch.com: What are the main findings of the study? Answer: The New York State Department of Health (NYSDOH) Overweight and Obesity Brief was derived from information gathered for the NYS Behavioral Risk Factor Surveillance System (BRFSS). The BRFSS is an annual statewide telephone survey of adults administered by the provide information on behaviors, risk factors, and utilization of preventive services. The survey conducted in 2011 found that nearly 25% of adults in NYS are obese and another 36% overweight. It also found that obesity rates are higher among adults who are Black (32.5%), earn an annual household income less than $25,000 (26.8%), have less than a college education (27.1%), or are currently living with a disability (34.9%). These findings bring to light that social and economic factors in our communities can be a major contributor to health disparities, like greater risk of obesity among people of color, low income individuals, and people who are disabled.

MedicalResearch.com Interview with: Nisa M. Maruthur, MD, MHS Assistant Professor of Medicine & Epidemiology The Johns Hopkins University Early Response to Preventive Strategies in the Diabetes Prevention Program MedicalResearch.com: What are the main findings of the study? Dr. Maruther: For patients engaged in a lifestyle intervention to prevent diabetes, weight loss early on (at 6 months) is an extremely strong predictor of whether they will develop diabetes down the road.  Even in the setting of substantial weight loss (>10%) at 6 months, it is still beneficial to lower fasting glucose.  These results are unique in that we previously understood that weight loss over time (years) is important to prevent diabetes, but now we know the impact of early weight loss on longer-term diabetes risk.

MedicalResearch.com Interview with Prof. Eyal Sheiner MD PhD Senior Obstetrician

Soroka Medical Center, Israel

MedicalResearch.com: What are the main findings of the study? Dr. Sheiner: The study was aimed to investigate whether a history of preterm delivery (PTD) poses a risk for subsequent maternal long-term cardiovascular morbidity. During the study period 47,908 women met the inclusion criteria; 12.5% (n=5992) patients delivered preterm. During a follow-up period of more than ten years, patients with PTD had higher rates of simple as well as complex cardiovascular events and higher rate of total cardiovascular related hospitalizations. A linear association was found between the number of previous PTD and future risk for cardiovascular hospitalizations (5.5% for two or more PTD, 5.0% for one PTD vs. 3.5% in the comparison group; P<0.001). The association remained significant for spontaneous vs. induced PTD and for early (<34 weeks) as well as late (34-36+6 weeks) PTD. In a Cox proportional hazards model that adjusted for pregnancy confounders such as labor induction, diabetes mellitus, preeclampsia and obesity, PTD was independently associated with cardiovascular hospitalizations (adjusted HR 1.4, 95% CI 1.2-1.6).
