MedicalResearch.com Interview with Dr. Sylvia Santosa, PhD Department of Exercise Science Concordia University Department of Exercise Science Montreal, Quebec, Canada H4B 1R6Dr. Sylvia Santosa, PhD Department of Exercise Science Concordia University Department of Exercise Science Montreal, Quebec, Canada H4B 1R6 MedicalResearch.com: What are the main findings of the study? Dr. Santosa: Our results show that postmenopausal women burn less fat making more available to be stored.  Our results also suggest that greater fat storage in postmenopausal women are likely to be attributed to changes in the pathways our fat cells use to store fat.  We found that some of the proteins that help our fat cells store fat were more active and this greater activity corresponded with the amount of fat stored from our circulation.

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…)

 MedicalResearch.com Interview with: Christer Hublin Apulaisylilääkäri, neurologian dosentti (Helsingin yliopisto) - Assistant Chief Medical Officer, Docent (Adjunct Professor) in Neurology (Helsinki University) Unilääketieteen erityispätevyys (Suomen lääkäriliitto) Sleep medicine specialist (NOSMAC/ESRS) Työterveyslaitos - Finnish Institute of Occupational Health FIN-00250 Helsinki Finland MedicalResearch.com What are the main findings of the study? Answer: We found in an adult twin cohort (the Finnish Twin Cohort) that the proportion of variance in sleep length accounted for by genetic effects was relatively low (about one third) but stable (correlation 0.76 over a period of 15 years.). In contrast, the proportion of variance accounted for by environmental effects was high (about 0.7) and these effects were less stable (correlation over the time period 0.18). The proportion of short sleepers was more than doubled in both genders, whereas in the proportion of long sleepers no major change was seen during the follow-up. To our knowledge, this is the first longitudinal study providing data on the contribution of genetic factors to stability and change of sleep length over time. (more…)

MedicalResearch.com Author Interview: Jun J. Yang, Ph.D. Assistant Member Dept. of Pharm. Sci. St. Jude Children's Research Hospital 262 Danny Thomas Pl., MS313 Memphis, TN 38105 MedicalResearch.com: What are the main findings of the study? Dr. Yang: We performed a comprehensive survey of inherited genetic variations for their contribution to the susceptibility of acute lymphoblastic leukemia (ALL), the most common cancer in children. This is by far the largest study of its kind (in terms of the number of subjects involved), and also the first one to include multi-ethnic populations. We identified 4 genomic loci related to the predisposition to ALL, 2 of which contributed to racial differences in the incidence of ALL.  This study provided unequivocal evidence for inherited susceptibility of childhood ALL and pointed to novel biology of the pathogenesis of this disease.

MedicalResearch.com Interview with Dr. Boelens Pediatric Blood and Marrow Transplantation Program, University Medical Center Utrecht, Utrecht, Netherlands MedicalResearch.com: What are the main findings of the study? Dr. Boelens: For children with Hurler’s syndrome, the receipt of a hematopoietic cell transplant (HCT) early in life with the best available human leukocyte antigen (HLA)-matched donor offers the best event free survival (EFS). Also, HCT with a well matched unrelated cord blood unit is particularly attractive as the unit is readily available. (more…)

MedicalResearch.com Interview with :Stig E. Bojesen Staff specialist, MD, PhD, DMSci Dept. of Clinical Biochemistry, Copenhagen University Hospital Herlev Hospital DK-2730 Herlev DenmarMedicalResearch.com Interview with Stig E. Bojesen Staff specialist, MD, PhD, DMSci Dept. of Clinical Biochemistry, Copenhagen University Hospital Herlev Hospital  DK-2730 Herlev  Denmark MedicalResearch.com: What are the main findings of the study?

Dr. Bojesen: The most interesting findings were the increased risk of early death after cancer by decreasing telomere length – measured even before the cancer disease surfaced in the individual. This association was present even after adjusting for all known markers of adverse prognosis. We did not expect this, but it has important implications for how we might apply this marker in the management of cancer patients. The second - and also important and unexpected finding - was the overall lack of association with risk of cancer, after adjustment for the most common ordinary risk factors like age, gender, smoking and so on. This was in contrast to former meta-analyses and many other smaller studies suggesting increased cancer risk with decreasing telomere length. We could reject this hypothesis with considerable statistical power. (more…)

MedicalResearch.com Interview with: Yoshihiro Kokubo, MD, PhD, FACC, FAHA, FESC Department of Preventive Cardiology, National Cerebral and Cardiovascular Center, 5-7-1, Fujishiro-dai, Suita, Osaka, MedicalResearch.com: What are the main findings of the study? Dr. Kokubo:  In this study, higher green tea (2 or more cups/day) and coffee (3 to 6 times/week, 1 or more cups/day) consumption were found to be inversely associated with the incidences of cardiovascular disease and stroke. Higher green tea (2 or more cups/day) or coffee (1 or more cups/day) consumption reduced the risks of cardiovascular disease, strokes, and its subtypes, especially in intracerebral hemorrhage (P for interaction between green tea and coffee=0.04).

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.

Allergies, Author Interviews / 15.03.2013

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).

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. (more…)
Author Interviews, Cancer Research, JNCI, Lung Cancer, NEJM / 08.03.2013

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. (more…)
