MedicalResearch.com eInterview with: Linden Oliver, MA, Clinical Research Coordinator University of Pennsylvania Behavioral Sleep Medicine Research Program Philadelphia, Pa MedicalResearch.com: What are the main findings of the study? Answer: We found that less sleep is associated with greater suicide risk in those with insomnia. Specifically, we looked at suicide risk in people with insomnia, and also asked how much sleep they got in the past month. In those with some suicide risk, the likelihood of being high risk (versus low risk) decreased by 72% for every hour of sleep that person reported getting at night. (more…)

MedicalResearch.com Author Interview: Dr. Steven A. Branstetter, PhD The Pennsylvania State University, 315 E. HHD, University Park, PA 16810.Dr. Steven A. Branstetter, PhD The Pennsylvania State University, 315 E. HHD, University Park, PA 16810. MedicalResearch.com: What are the main findings of the study? Dr. Branstetter: This study demonstrated that the time to the first cigarette of the day after waking is associated with increased levels of a NNAL, a metabolite of a powerful tobacco-specific carcinogen, NNK -- even after controlling for the total number of cigarettes smoked per day. For years, the time to the first cigarette of the day after waking was one of several questions assessing nicotine dependence on the Fagerstrom Test for Nicotine Dependence (FTND), the gold standard questionnaire int he field. Over time, it was found that much of the predictive validity of the FTND was due to the time to first cigarette item. Researchers have found that single time to first cigarette item was highly correlated with other measures of nicotine dependence, and was predictive of more difficulty quitting smoking and increased intake of nicotine. Our current study demonstrates that this behavioral measure, is predictive of exposure to the cancer-causing components of cigarettes, regardless of the total number of cigarettes smoked per day. The results suggest that researchers, clinicians and smokers can assess the level of nicotine dependence and potential cancer risk by looking at the time to the first cigarette of the day after waking.

Author Interviews, Prostate Cancer, University of Pennsylvania / 28.03.2013

MEDICALRESEARCH.COM INTERVIEW WITH Charnita Zeigler-Johnson, Ph.D., M.P.H. Research Assistant Professor CCEB University of Pennsylvania MEDICALRESEARCH.COM: What are the main findings of the study? Dr. Zeigler-Johnson: The main findings of the study are:
  • Younger African-American men diagnosed with advanced prostate cancer at an early age (under the age of 60) are more likely to have had a personal history of early-onset baldness (baldness by age 30.)
  • For older patients, this is not necessarily the case, and future studies will need to focus on which factors place men in this age group at risk for prostate cancer. (more…)
