Kelly R. Reveles, PharmD, PhD The University of Texas College of PharmacyMedicalResearch.com Interview with: Kelly R. Reveles, PharmD, PhD The University of Texas College of Pharmacy Medical Research: What are the main findings of the study? Dr. Reveles: Our study utilized data from the Centers for Disease Control and Prevention’s National Hospital Discharge Surveys. Patients were selected for this study if they were at least 18 years of age and had an International Classification of Diseases, 9th Revision, Clinical Modification (ICD-9-CM) code for Clostridium difficile infection (CDI) (ICD-9-CM code 008.45). We found that Clostridium difficile infection incidence increased from 4.5 CDI discharges/1,000 total discharges in 2001 to 8.2 CDI discharges/1,000 total discharges in 2010. Mortality varied over the study period with peak mortality occurring in 2003 (8.7%) and the lowest rate occurring in 2009 (5.6%). Median hospital length of stay (LOS) was 8 days and remained stable over the study period. In summary, the incidence of Clostridium difficile infection in U.S. hospitals nearly doubled from 2001 to 2010, with little evidence of recent decline. Additionally, there does not appear to be a significant decline in mortality or hospital LOS among patients with Clostridium difficile infection. (more…)

Chief Clinical Officer of iRhythm Technologies, Inc. Judy Lenane, R.N., M.H.A. Chief Clinical Officer of iRhythm Technologies, Inc.   Medical Research: What is atrial fibrillation and how common a problem is it among US adults? Dr. Gorelick: Nearly 3 million people in the US suffer from Atrial Fibrillation or “Afib,” an abnormal heart rhythm that causes the heart to beat rapidly and irregularly. While Afib can occur at any age, the incidence increases with age and the number of cases is expected to increase significantly in the coming years as the population ages. Approximately 5 percent of people 65 years and older and one in every 10 people over 80 years of age have Afib. It is more common in those with high blood pressure, heart disease or lung disease.

Stewart Agras, M.D. Professor of Psychiatry Emeritus Stanford University School of MedicineMedicalResearch.com Interview with: Stewart Agras, M.D. Professor of Psychiatry Emeritus Stanford University School of Medicine MedicalResearch: What was the study about? Dr. Agras: Family-based treatment (FBT) has been shown to be more effective than individual psychotherapy for the treatment of adolescent anorexia nervosa. This treatment focuses on helping the family to re-feed their child. The question posed in this study was whether Family-based treatment would have any advantages over Systemic family therapy (SyFT) focusing on family interactions that may affect the maintenance of the disorder. The participants were 164 adolescents with anorexia nervosa and their families – one of the largest studies of its type. (more…)

Pietro Manuel Ferraro, MD PhD Candidate Division of Nephrology Catholic University of the Sacred Heart Rome ItalyMedicalResearch.com Interview with: Pietro Manuel Ferraro, MD PhD Candidate Division of Nephrology Catholic University of the Sacred Heart Rome Italy Medical Research: What are the main findings of the study? Dr. Ferraro: We analyzed the association between physical activity and energy intake and the risk of developing kidney stones in three large cohorts of U.S. health professionals. The 215,133 participants included did not have any history of kidney stones when follow-up began. During 20 years of follow-up, 5,355 of them developed a kidney stone. Initially, we found that participants with higher physical activity levels had a reduced risk of developing stones in two of the three cohorts. However, after accounting for a number of factors that could potentially confound the association such as age, body mass index and dietary intake, the association was no longer significant. Similarly, energy intake was not associated with a reduced risk of developing kidney stones. (more…)

MedicalResearch.com Interview with: Tuomo Tompuri, MD Clinical Physiology and Nuclear Medicine Kuopio University Hospital, Finland Medical Research: What are the main findings of the study? Dr. Tompuri: Measures of the cardiorespiratory fitness should be scaled by lean mass instead of body weight, while aiming to enable comparison between the subjects. Our result is physiologically logical and confirms earlier observations of the topic. Scaling by body weight has been criticized, because body fat, per se, does not increase metabolism during exercise. We did observe that scaling by body weight introduces confounding by adiposity.

Dennis Kim, MD Los Angeles Biomedical Research Institute Researcher MedicalResearch.com Interview with: Dennis Kim, MD Los Angeles Biomedical Research Institute Researcher Medical Research: What are the main findings of the study? Dr. Kim: Laparoscopic cholecystectomy, a minimally invasive procedure to remove the gallbladder, is one of the most common abdominal surgeries in the U.S. Yet medical centers around the country vary in their approaches to the procedure with some moving patients quickly into surgery while others wait. Our study found gallbladder removal surgery can wait until regular working hours rather than rushing the patients into the operating room at night. The gallbladder is a pear-shaped organ on the upper right side of the abdomen that collects and stores bile, a digestive fluid produced by the liver. Gallbladders may need to be removed from patients who suffer pain from gallstones that block the flow of bile. In a laparoscopic cholecystectomy, surgeons insert a tiny video camera and special surgical tools through small incisions in the abdomen to remove the gallbladder. Occasionally, surgeons may need to create a large incision to remove the gallbladder, and this is known as an open cholecystectomy. We conducted a retrospective study of 1,140 patients at two large urban referral centers who underwent gallbladder removal surgeries. We found 11% of the surgical procedures performed at night (7 a.m.-7 p.m.) were converted to the more invasive procedure, open cholecystectomies. Only 6% of those who underwent the surgery during the day required the more invasive form of surgery. (more…)

Prof. Kivimäki: In our study, we pooled published and unpublished data from 222 120 men and women from the USA, Europe, Japan, and Australia. Of them, 4963 individuals developed type 2 diabetes during the mean follow-up of 7.6 years. This is the largest study to date on this topic. In an analysis stratified by socioeconomic status, the association between long working hours and diabetes was evident in the low socioeconomic status group, but was null in the high socioeconomic status group. The association in the low socioeconomic status group did not change after taking into account age, sex, obesity, physical activity, and shift working. So, the association was very robust. In brief, the main finding of our meta-analysis is that the link between longer working hours and type 2 diabetes was apparent only in individuals in the low socioeconomic status groups. (more…)

Dr. Lorraine Yeung Division of Birth Defects and Developmental Disabilities National Center on Birth Defects and Developmental Disabilities, CDCMedicalResearch.com Interview with: Dr. Lorraine Yeung Division of Birth Defects and Developmental Disabilities National Center on Birth Defects and Developmental Disabilities, CDC Medical Research: What are the main findings of the study? Dr. Yeung: In this report, we looked at the percentages of children who received various recommended clinical preventive services. We found that millions of infants, children, and adolescents in the U.S. did not receive key clinical preventive services. This report provides a baseline snapshot of the use of 11 key clinical preventive services before or shortly after the Affordable Care Act went into effect. A focus of the Affordable Care Act is on improving prevention of illness and disability and it does so by requiring new health insurance plans to provide certain clinical preventive services at no additional cost — with no copays or deductibles. This is important because we know increasing the use of these services can improve children’s health and promote healthy lifestyles that will enable them to reach their full potential. Some of the important findings in this report were:          In 2007, parents of almost eight in 10 (79 percent) children aged 10-47 months reported that they were not asked by healthcare providers to complete a formal screen for developmental delays in the past year.          In 2009, more than half (56 percent) of children and adolescents did not visit the dentist in the past year and nearly nine of 10 (86 percent) children and adolescents did not receive a dental sealant or a topical fluoride application in the past year.          Nearly half (47 percent) of females aged 13-17 years had not received their recommended first dose of HPV vaccine in 2011.          Approximately one in three (31 percent) outpatient clinic visits made by 11-21 year-olds during 2004–2010 had no documentation of tobacco use status; eight of 10 (80 percent) of those who screened positive for tobacco use did not receive any cessation assistance.          Approximately one in four (24 percent) outpatient clinic visits for preventive care made by 3-17 year olds during 2009-2010 had no documentation of blood pressure measurement.

Dr. Courtet: Depressed outpatients who are beginning the treatment with a SSRI at higher dose than recommended present an increased risk (x2) of worsening of suicidal ideation during the first 6 weeks of treatment. This is consistent with the study by Miller et al published in the same journal few weeks ago, reporting a double risk of suicide attempt in young subjects (<24 yrs) who are begun an SSRI at higher dose than recommended. Our results showed that the increased suicide risk with the high dose of SSRI is not restricted to youngsters and is independent of the severity of the depression. (more…)

Prof. Moses Elisaf Professor of Internal Medicine University of Ioannina, GreeceMedicalResearch.com Interview with: Prof. Moses Elisaf Professor of Internal Medicine University of Ioannina, Greece Medical Research: What are the main findings of the study? Dr. Elisaf: We evaluated the effects of rosuvastatin in two groups of hyperlipidemic patients: one group had impaired fasting glucose (IFG) while the second group had normal fasting glucose. After study end, both groups had similar changes in their lipidemic profile. However, patients with IFG had a significant greater decrease in the cholesterol concentration of the more atherogenic small dense low-density lipoprotein (sdLDL) particles (-65.7%) compared with controls (-38.5%). Moreover, a greater increase in the mean LDL particle size was observed in the impaired fasting glucose group (+1.5% vs +0.4%). In addition, redistribution from the more atherogenic sdLDL to large buoyant LDL (lbLDL) subfractions was observed in the IFG group. (more…)

Dr. Griffiths: This study found that hospital nurses who are working on a 2 shift system, where care is provided by nurses working long shifts of 12-13 hours, report lower quality and safety of care than nurses who work a traditional three shift system where nurses typically work shifts of 8 hours. We also found that nurses who were working overtime reported lower quality and safety of care. We found that these shifts are common in some European countries – most notably Poland, Ireland and England. (more…)
