MedicalResearch What are the main findings of the study?Dr. Serlie: We studied the effects of hypercaloric high sugar or high fat/high sugar drinks consumed with the 3 main meals (representing an increase in meal size) or in between the 3 main meals (representing an increase in meal frequency or snacking). All subjects gained a similar amount of body weight but only the ones that snacked showed an increase in liver and abdominal fat. This suggests that besides caloric content and diet composition, eating pattern independently contributes to liver and abdominal fat accumulation. We also observed a trend for a decrease in hepatic insulin sensitivity in the high fat/high sugar frequency group only.

MedicalResearch: What are the main findings of the study?Dr. Soares-Miranda: Modest physical activity, such as the distance and pace of walking, is important for the heart’s electrical well being of older adults. In our study, older adults that increased their walking pace or distance had a better heart rate variability when compared with those that decreased their walking pace or distance. Our results suggest not only that regular physical activity later in life is beneficial, but also that certain beneficial changes that occur may be reduced when physical activity is reduced. This supports the need to maintain modest physical activity throughout the aging process. Even small increases can lead to a better health, while reducing physical activity has the opposite effect. So, any physical activity is better than none, and more is better. (more…)

MedicalResearch: What are the main findings of the study?Answer: Increasingly, men with low-risk prostate cancer are undergoing a close monitoring regimen called active surveillance, instead of moving forward immediately with treatment. However it is still unclear which men will develop evidence for worsening or more aggressive disease during active surveillance. In this study of 154 men with Gleason 6 prostate cancer followed for 38 months, we found that low levels of free testosterone were significantly associated with increased risk of developing more aggressive disease. We found no significant association with total testosterone concentrations, although there was a general trend towards increased risk with lower levels.

MedicalResearch.com: What are the main findings of the study?Dr. Sommers: We find that over the first four years since Massachusetts' 2006 comprehensive health reform law, all-cause mortality in the state fell by 2.9%, compared to a similar population of adults living in counties outside Massachusetts that did not expand insurance during this period. We also found that the law reduced the number of adults in Massachusetts without insurance, reduced cost-related barriers to care, increased use of outpatient visits, and led to improvement in self-reported health. Overall, we estimate that the health reform law prevented over 320 deaths per year in the state - or one life saved per 830 adults gaining health insurance. Mortality rates declined primarily due to fewer deaths from causes amenable to health care, such as cancer, infections, and heart disease. We also found that the health benefits were largest for people living in poor counties in the state, areas with higher percentage of uninsured adults before the law was passed, and for minorities.

MedicalResearch: What are the main findings of the study?Dr. Singal: We conducted a meta-analysis of current studies to characterize the association between hepatocellular carcinoma surveillance and early detection, curative treatment rates, and overall survival in patients with cirrhosis. We identified 47 studies with 15,158 patients, of whom 6,284 (41.4%) had hepatocellular carcinoma detected by surveillance. Hepatocellular carcinoma surveillance was associated with improved early stage detection (OR 2.08, 95% CI 1.80–2.37) and curative treatment rates (OR 2.24, 95% CI 1.99–2.52). These associations were robust to several sensitivity analyses, including study design, study location, and study period. Hepatocellular carcinoma surveillance was associated with significantly prolonged survival (OR 1.90, 95% CI 1.67–2.17), which remained significant in the subset of studies adjusting for lead-time bias. Three-year survival rates were 50.8% among patients who underwent surveillance, compared to only 28.2% among hepatocellular carcinoma patients with tumors detected outside of a surveillance program.

West Midlands Research Collaborative,

MedicalResearch.com: What are the main findings of the study? Mr. Bhangu: Out study was based on a novel collaborative approach, spanning 95 centres in the UK. It was led by surgical trainees, who form a natural network and work in a rotational pattern. These networks will mature to allow a future of clinical research to be embedded into routine NHS care.
Our study found no increase in complications based on weekend operating. It’s possible that patients present differently at weekends, or that surgeons select less complex patients to operate upon. A key secondary finding is that patients operated on at weekends were less likely to undergo laparoscopy. This means that they are exposed to different processes of care, which may introduce risk. This may be a surrogate marker for other differences in weekend care that require exploration.
