MedicalResearch.com Interview with : Verena Sengpiel, researcher Institute of Clinical Sciences, Sahlgrenska Academy University of Gothenburg MedicalResearch.com: What are the main findings of the study? Response: 1. Coffee, but not caffeine, consumption was associated with marginally increased gestational length but not with the risk of spontaneous preterm delivery. 2. Caffeine intake was consistently associated with decreased birth weight and increased odds of SGA (small for gestational age). This might have clinical implications as even caffeine consumption below the recommended maximum (200 mg/d in the Nordic countries and USA, 300 mg/d according to WHO) was associated with increased risk for SGA.

Dr. Anna Nordström MD Department of Community Medicine and Rehabilitation, Rehabilitation Medicine, Umeå University, SE-901 87 Umeå, SwedenMedical Research.com Interview with Dr. Anna Nordström MD Department of Community Medicine and Rehabilitation, Rehabilitation Medicine, Umeå University, SE-901 87 Umeå, Sweden Medical Research.com: What are the main findings of the study? Dr. Nordström: We have found that low cognitive function and factors related to low socioeconomic status and intoxications are strong independent risk factors for mild traumatic brain injury in men. Medical Research.com: Were any of the findings unexpected? Dr. Nordström:  Our knowledge of risk factors that predispose people to sustaining such injury is limited. Previous research has inferred that mild traumatic brain injuries have important long-term consequences on cognitive function. However, we found similar deficits in cognitive function in subjects that sustained a mild traumatic brain injury before and after cognitive testing. Thus our data suggest that the injury itself may not reduce cognitive function.

MedicalResearch.com Matthieu Picard, MD, FRCPC Hôpital Maisonneuve-Rosemont Université de Montréal Montréal, Qc, Canada MedicalResearch.com: What are the main findings of the study? Dr. Picard: We found that patients reporting a history of penicillin allergy were often treated with penicillins despite their history of allergic reaction to that drug. In this study, which took place in a large tertiary-care academic hospital without allergists on staff, more than half of patients with a presumed penicillin allergy and a need for antibiotics were treated with beta-lactams, a class of antibiotics that includes penicillins and drugs that can cause allergic reactions in penicillin allergic individuals because of cross-reactivity.

Gabriel Brooks MD Fellow, Medical Oncology Dana-Farber Cancer InstituteMedicalResearch.com Interview with Gabriel Brooks MD Fellow, Medical Oncology Dana-Farber Cancer Institute MedicalResearch.com: What are the main findings of the study? Dr. Brooks: First, we found that there is substantial regional variation in Medicare spending for patients with advanced cancer.  For patients with a new diagnosis of advanced stage cancer, spending in the six months following diagnosis varied by 32% between regions in the highest and lowest quintiles of spending.  And for patients who died from cancer, spending in the last six months of life varied by 41% between the highest and lowest spending regions. Second, we tested the association between area-level spending and survival from the time of advanced cancer diagnosis.  We found that there was no consistent association between increasing spending and survival for any of the five cancer sites included in our study (non-small cell lung cancer, colorectal cancer, pancreas cancer, breast cancer and prostate cancer).

MedicalResearch.com Author Interview: Dr. Donald K. Milton, MD, Dr.P.H dr_donalk_k_miltonDr. Donald K. Milton, MD, Dr.P.H Professor and Director Maryland Institute for Applied Environmental Health University of Maryland MedicalResearch.com: What are the main findings of the study? Dr. Milton: We found that total viral copies detected by molecular methods were 8.8 times more numerous in fine (≤5 µm) than in coarse (>5 µm) aerosol particles and that the fine particles from cases with the highest total number of viral RNA copies contained infectious virus. Surgical masks reduced the overall number of RNA copies by 3.4 fold.

Dr. Martin C. Tammemägi Professor (Epidemiology) Brock University Department of Community Health Sciences Walker Complex – Academic South, Room 306 St. Catharines, Ontario, Canada L2S 3A1Medical Research.com Author Interview: Dr. Martin C. Tammemägi Professor (Epidemiology) Brock University Department of Community Health Sciences St. Catharines, Ontario, Canada L2S 3A1 Medical Research.com What are the main findings of the study?  Dr. Tammemägi: Our study accomplished three things: 1. We presented an updated Lung Cancer Risk Prediction Model, which compared to our previously JNCI-published model, incorporates more predictors but is simpler to use because we changed the way we modeled nonlinear effects. 2. We demonstrated that using the Lung Cancer Risk Prediction Model to select individuals for lung cancer screening was much more effective than using the National Lung Screening Trial (NLST) enrolment criteria.  41.3% fewer lung cancers were missed.  Sensitivity and positive predictive value of identifying individuals who develop lung cancer were significantly improved.  Shortly after our NEJM paper was published, Ma et al published in CANCER their findings that 8.6 million Americans are NLST-criteria positive and if they were CT screened under ideal conditions 12,000 lung cancer deaths would be averted.  Our NEJM article findings indicate that an additional 2,764 lives would be saved if the selection criteria had enrolled 8.6 million individuals for screening based on highest risk by our Lung Cancer Risk Prediction Model. 3. Importantly, using NLST data we demonstrated that the beneficial effect of CT screening did not vary by model predicted lung cancer risk.
Author Interviews, Clots - Coagulation, NEJM / 08.03.2013

Author Interview: Sam Schulman M.D., FRCPC(C) Professor, Division of Hematology and Thromboembolism, Department of Medicine Associate Professor, Medicine, Karolinska Institute, Stockholm, Sweden Director, Clinical Thromboembolism Program Hamilton Health Sciences, Hamilton General Hospital, Hamilton, OntarioMedicalResearch.com  Author Interview: Sam Schulman M.D., FRCPC(C) Professor, Division of Hematology and Thromboembolism, Department of Medicine Associate Professor, Medicine, Karolinska Institute, Stockholm, Sweden Director, Clinical Thromboembolism Program Hamilton Health Sciences, Hamilton General Hospital, Hamilton, Ontario MedicalResearch.com: What are the main findings of the study? Response: Similar effect of dabigatran  as warfarin, 92% risk reduction compared to placebo. The risk of bleeding is reduced by almost 50% compared to warfarin but in comparison with placebo there is an increased risk of minor bleeding. No routine coagulation monitoring or dose adjustments are required, making the treatment convenient for patients and physicians.
