Perrin, MD, MPH Associate Vice Chancellor for Research, and Director, Office of Research Development University of North Carolina at Chapel Hill and Associate Professor Department of Pediatrics, Division of General Pediatrics and Adolescent Medicine University of North Carolina at Chapel Hill, School of Medicine Chapel Hill, NC 27599-7225MedicalResearch.com: What are the main findings of the study?Dr. Perrin: The study included a large, diverse sample of 863 low-income parents of two-month-olds participating in Greenlight, an obesity prevention trial taking place at four medical centers: UNC, New York University, Vanderbilt University and the University of Miami. Among all of the parents, behaviors that are thought to be related to later obesity were highly prevalent. Exclusive formula feeding was more than twice as common (45 percent) as exclusive breastfeeding (19 percent). Twelve percent had already introduced solid food, 43 percent put infants to bed with bottles, 23 percent propped bottles instead of holding the bottle by hand (which can result in overfeeding), 20 percent always fed when the infant cried, and 38 percent always tried to get their children to finish their milk. In addition, 90 percent of the infants were exposed to television and 50 percent actively watched TV (meaning parents put their children in front of the television in order to watch). There were differences in these behaviors by race and ethnicity, and study results show that culturally-tailored counseling should be offered to parents of different backgrounds who may feed and play with their children differently.(more…)

Dr. Maarten de Rooij MD, PhD Candidate Department of Radiology, Radboud University Nijmegen Medical Centre, Nijmegen, Gelderland 6525 GA, The NetherlaMedicalResearch.com Interview with:Dr. Maarten de Rooij MD, PhD Candidate Department of Radiology Radboud University Nijmegen Medical Centre Nijmegen, Gelderland 6525 GA, The Netherlands MedicalResearch.com: What are the main findings of the study?Dr. de Rooij : Prostate cancer is the most common cancer in men and the second leading cause of cancer related death. The current diagnosis is based on ‘random or blind’ systematic transrectal ultrasound guided prostate biopsies in men with an elevated PSA. This can lead to over-diagnosis and over-treatment of prostate cancer, but can also miss important tumors. The role of multiparametric MRI (mpMRI) to improve the diagnosis of prostate cancer is evolving. In this meta-analysis we determined the diagnostic accuracy of mpMRI for the detection of prostate cancer. Our analysis included 7 studies using mpMRI which showed high overall specificity (0.88; 95% CI 0.82-0.92), with variable but high negative predictive values (0.65 - 0.95) and sensitivities (0.74; 95% CI 0.66-0.81).

We found that most (64%) patients were not evaluated according to the guidelines, that there was substantial variation in the evaluation, and that the evaluation depended largely on the type of hematuria and physician specialty. Only 5% of patients were found to have urologic cancer, and all of them were evaluated according to the guidelines. No additional urologic cancers were diagnosed in patients in whom guidelines were not followed; however, since not all patients were tested thoroughly, occult malignancies may have been present.(more…)

MedicalResearch.com Interview with:Dr Rachel J Sacks Jefferiss Wing, St Mary's Hospital Imperial College Healthcare NHS Trust, London UKMedicalResearch.com: What is the background of this study?Dr. Sacks: 2247 anonymous questionnaires were completed by young women, aged 13-19 years old, attending sexual health services across England, looking at their HPV vaccination outcomes and prevalence of risk factors associated with HPV acquisition and cervical cancer development, and comparing the survey results with national data where available. Known HPV acquisition and cervical cancer development risk factors include cigarette smoking, early age at first intercourse, increasing number of lifetime partners, co-infection with other sexually transmitted infections.MedicalResearch.com: What are the main findings of the studyDr. Sacks:
  • Young women, aged 13 to 19 years old attending sexual health services across England had higher prevalence of known risk factors associated with HPV acquisition and cervical cancer development, compared with national data.
  • Survey respondents had lower HPV vaccination offer and lower HPV vaccination completion rates than nationally.
  • Subgroups within the survey respondents were identified as having a significantly lower offer and significantly lower completion rate of the HPV vaccination. These subgroups included respondents from London, those of non-white ethnicities, 17 to 19 year olds, smokers and those not in education, employment or training (NEETs).
  • The highest risk individuals, in terms of HPV related risk factors, were the least likely to be offered and additional the least likely to complete the HPV vaccination course.
  • Currently sexual health services in England are not involved in the delivery of the HPV vaccination programme and this is felt to be a huge missed opportunity for the primary prevention of HPV acquisition and its potential sequelae. Sexual health services should be included as a supplementary HPV vaccination delivery site in order to target these particularly vulnerable young women and to increase the success of the HPV vaccination programme in England.

Gunderson, PhD, MS, MPH Senior Research Scientist, Cardiovascular and Metabolic Section Division of Research, Kaiser Permanente Northern California Oakland, CA 94612-2304 MedicalResearch.com: What are the main findings of the study?Dr. Gunderson: The study found that:- Gestational diabetes is a pregnancy complication that reveals a woman’s greater risk of future heart disease.- Women who experience gestational diabetes face an increased risk of subclinical atherosclerosis (early heart disease) even if they do not develop type 2 diabetes or the metabolic syndrome years after pregnancy.- Study participants with a history of gestational diabetes who did not develop diabetes or metabolic syndrome showed a greater carotid artery wall thickness (marker of early atherosclerosis) compared to those who never experienced gestational diabetes. The vessel narrowing also could not be attributed to obesity or other risk factors for heart disease that were measured before pregnancy.- Weight gain and blood pressure elevations in women with gestational diabetes were responsible for these differences in the artery wall thickness.(more…)

Rajiv Chowdhury MD, PhD Cardiovascular Epidemiologist Department of Public Health and Primary Care University of CambridgeMedicalResearch.com Interview with: Rajiv Chowdhury MD, PhD Cardiovascular Epidemiologist Department of Public Health and Primary Care University of CambridgeMedicalResearch.com: What are the main findings of the study?Dr. Chowdhury:Total saturated fatty acid, whether measured as a dietary intake variable or in the bloodstream as a biomarker, was not associated with coronary disease risk in combining all available prospective observational studies. Similarly, there were non-significant overall associations in the prospective studies that involved assessments of total monounsaturated fatty acids, long-chain omega-3 and omega-6 polyunsaturated fatty acids.However, we found diversity in the observational associations between specific circulating long-chain omega-3 and omega-6 fatty acids with coronary risk, with some evidence that circulating levels of eicosapentaenoic and docosahexaenoic acids (ie, the two main types of long-chain omega-3 polyunsaturated fatty acids), and arachidonic acid are each associated with lower coronary risk. Similarly, within saturated fatty acids, there were positive, however, non-significant associations observed for circulating blood composition of palmitic and stearic acids (found largely in palm oil and animal fats, respectively), whereas circulating margaric acid (a milk fat) had a significant inverse association.Additionally, when we investigated the randomised controlled trials that reported on the effects of omega-3 and omega-6 fatty acids on reducing coronary outcomes, there was no significant overall association observed.(more…)

Associate Chair & Residency Program Director The Reading Hospital Department of OB/GYN Reading, PA 19612-6052MedicalResearch.com: What are the main findings of the study?Dr. Schnatz: In a subsample of 576 women from the parent WHI CaD (calcium plus vitamin D supplementation) trial* , there was a significant (38%) increase in mean serum 25OHD3 concentrations after two years (95% CI 1.29-1.47, p< 0.001) for women randomized to CaD (24.3ng/mL vs. 18.2 ng/mL).Women randomized to CaD had a 4.5 mg/dL mean decrease in LDL-C which was statistically significant. After accounting for serum 25OHD3 concentration, the effect of CaD was attenuated, suggesting that higher concentrations of 25OHD3, in response to CaD supplementation, are associated with improved LDL-C.In observational analyses, higher concentrations of 25OHD3 were associated with significantly higher HDL-C along with significantly lower LDL-C and TG concentrations.* 1,000 mg of elemental calcium plus 400 IU of vitamin D3 daily (more…)

Dr Tobias Teichert Assistant Professor of Psychiatry University of Pittsburgh Pittsburgh, PA 15261MedicalResearch.com Interview with:Dr Tobias Teichert Assistant Professor of Psychiatry University of Pittsburgh Pittsburgh, PA 15261 MedicalResearch.com: What are the main findings of the study?Dr. Teichert: "Our study provided three main findings:First, we measured how long it takes subjects to allocate attention to a relevant target and how effectively they can block out the distractors. We found that after 120 msec selective attention is fully engaged and completely blocks out the distractor. Based on this finding, we predicted that subjects should be able to improve decision accuracy by delaying decision onset, and that this should be more effective than simply prolonging the whole decision process.Most importantly, we found that subjects indeed use this more effective way of improving decision onset: On average, subjects delayed decision onset by about 50 msec when we asked them be as accurate as possible. The good news is that people seem to use this more optimal mechanism automatically, without being told to do so and without being aware of what they do. The bad news is that we don’t seem to be using this skill quite as effectively as we could. In our case, subjects could have improved accuracy even further by delaying decision onset by an additional 50 ms. However, taken together, our findings show that decision onset is to some degree under cognitive control, and that we might be able to devise training strategies to harness its full potential” (more…)

We found out that each minute the treatment can be delivered faster granted on average 1.8 days of extra healthy life (95% prediction interval 0.9 to 2.7). In practice, this means that each 15 minute decrease in treatment delays provides an average equivalent of one month of additional disability-free life. (more…)

MedicalResearch.com Interview with: Prof. Dr. Sven Cichon, PhD Director, Division of Medical Genetics University Hospital Basel Human Genomics Research Group Department of Biomedicine University of Basel Basel, SwitzerlandMedicalResearch.com: What were the main findings of the study?Answer: We have identified two new gene regions that represent pieces of the jigsaw puzzle of genetic and non-genetic factors that lead to the development of bipolar disorder. One is the gene ADCY2 (Adenylate Cyclase 2) which is involved in signal transmission within nerve cells. The other region comprises two genes, both presumably playing a role in neurodevelopmental processes (MIR2113 and POU3F2). Importantly, these results come out of the largest of these kinds of studies so far, involving altogether more than 24,000 people. (more…)

MedicalResearch.com Interview with: Dingli Xu, MD From Department of Cardiology Nanfang Hospital, Southern Medical University, Guangzhou, ChinaMedicalResearch.com: What are the main findings of the study?Answer:Our study showed that after controlling for multiple cardiovascular risk factors, the blood pressure range at 120-139/80-89 mm Hg (defined as ‘prehypertension’ in JNC 7), is significant associated with long-term risk of stroke. The results were consistent across stroke type, stroke endpoint, age, study characteristics, follow-up duration, and ethnicity. More importantly, even low-range prehypertension (BP 120-129/80-84mmHg) increased the risk of stroke compared with optimal BP (<120/80 mm Hg), and the risk was higher in individuals with high-range prehypertension (BP 130-139/85-85mmHg). In particular, we found that compared with individuals with optimal blood pressure individuals with low-range prehypertension were 44% more likely to develop stroke, and this risk was even greater (95%) in individuals with high-range prehypertension.(more…)

While discontinuation was common with RCTs involving patients (28%), it was rare in RCTs with healthy volunteers (3%). The most commonly reported reason for RCT discontinuation was poor recruitment (10% of included RCTs). We found that trials with investigator sponsor (versus industry) and those with smaller planned sample sizes were at higher risk of discontinuation due to poor recruitment. Of discontinued RCTs, up to 60% remained unpublished. Trial investigators rarely informed research ethics committees about trial discontinuation and publication.(more…)

They were also more likely to progress from experimenting with tobacco cigarettes to becoming regular smokers.Teen smokers who used e-cigarettes were more likely to be planning to quit in the next year and less likely to have abstained from smoking recently, compared to smokers who had never used e-cigarettes. They were also more likely to be heavier smokers (smoke more cigarettes per day) than those who had never tried e-cigarettes, that being said there are eliquids available that have no nicotine content whatsoever and these are therefore a much healthier option, you can see a wide variety of these at Gourmet E-Liquid.

Watertown, MA 02472MedicalResearch.com: What are the main findings of the study?Answer: For this study, we analyzed health insurance data from a cohort of community-dwelling individuals between the ages of 30-79 at baseline, in Boston, MA. Massachusetts health care reform legislation, including the expansion of Medicaid, resulted in substantial overall gains in coverage in our study population. Despite being targeted by the law, the working poor (those currently working for pay, either part- or full-time and earning less than 200% of the US federal poverty threshold for household size) continued to report lower rates of insurance coverage following reform (13.3% without insurance), compared to the both non-working poor (4.7% without insurance) and the not poor (5.0% without insurance).
