Medical Research: What are the main findings of the study?Dr. Merom:In a cohort of 1667 older Australian men (mean age 76.8 years) data on incident falls were collected every four months by telephone interview. We compared the rate of falling over 48 months of follow-up of men who participated in golf, Calisthenics, lawn balls, aerobic machines and swimming. We found that only swimming was associated with 33% reduction in falls occurrence. We also found that swimmers performed better on balance tests in our baseline measurements. In particular on the postural stability test and for those whose leisure activity was only swimming, apart from walking and other lifestyle activities.

Melanoma Institute Australia and the University of SydneyMedical Research: Could you provide some background on this project? Why did you decide to do this research project? What prior work led up to this latest paper?Dr. Long: Pre-clinically, we had data that showed that the combination of BRAF inhibitor + MEK inhibitor
Decreased skin proliferative toxicity seen with BRAF inhibitors alone (seen as hyperproliferative lesions in rats)
and delayed the emergence of resistance I.e. The tumours in the mice reduced in size more, and stayed reduced for longer.We then confirmed this concept in a randomised phase 2 study, although it was not powered for a definitive progression free survival (PFS_ difference like a phase 3 trial is, we saw a strong difference in response rate and in PFS, yet there were only 54 patients per arm.

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.

Medical Research: What are the main findings of the study?Dr. Curigliano:In the CLEOPATRA study, 808 patients from 25 countries with HER2-positive metastatic breast cancer were randomised to receive first-line placebo/trastuzumab/docetaxel or pertuzumab/trastuzumab/docetaxel. Randomisation was stratified by geographic region and neo/adjuvant chemotherapy.
At ESMO 2014 the CLEOPATRA researchers reported results of a final prespecified OS analysis (February 2014). This overall survival (OS) analysis was planned when ≥385 deaths were reported. The log-rank test, stratified by prior treatment status and geographic region, was used to compare OS between arms, applying the threshold of p ≤ 0.0456. Subgroup analyses of OS were performed for stratification factors and other key baseline characteristics.At median follow-up of 50 months (range 0 to 70 months), the statistically significant improvement in OS in favour of pertuzumab/trastuzumab/docetaxel arm was maintained (HR = 0.68, p = 0.0002). Median OS was 40.8 months in the placebo arm and 56.5 months in the pertuzumab arm, with difference of 15.7 months. The PFS in pertuzumab arm was 18.7 vs 12.4 months in placebo arm, HR 0.68 (p < 0.0001).

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.

MedicalResearch.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…)

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.

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.

MedicalResearch.com Interview with:Dr. Holly R. Wyatt, MD
Endocrine Society spokeswoman
Associate Professor, University of Colorado Denver
Medical Director, Anschutz Health and Wellness Center
Medical Director, ABC’s TV series “Extreme Weight Loss”.
MedicalResearch.com Editor’s note: Dr. Wyatt is a nationally known expert on obesity and weight control. Dr. Wyatt is co-founder of ‘The State of Slim’ behavioral weight management program and has been the National Program Director for the Centers for Obesity Research and Education (C.O.R.E.) since 1999. Dr. Wyatt publishes extensively in the obesity and metabolism literature including publications in the NEJM, Obesity, Annals of Internal Medicine, Journal of Clinical Endocrinology & Metabolism and American Journal of Clinical Nutrition among others. Dr. Wyatt kindly answered questions regarding weight loss and maintenance for the MedicalResearch.com audience.
Medical Research: How did you become interested in weight control?Dr. Wyatt: Basically, because I struggled with my weight all my life. I was always planning on going to medical school and had been interested in learning more about the science of weight gain and metabolism, but at the time the subject was not well studied. When I came to the University of Colorado for my medical residency, I met researchers who were investigating the growing problem of obesity and were passionate about finding effective strategies for weight management. I have been active in clinical practice and obesity research since that time.
Medical Research: Why does weight loss or even weight maintenance become so much harder as we age?
Dr. Wyatt: We don’t know all the reasons for certain, but the problem is most likely multifactorial.
First, as we age we lose muscle mass. To a large degree, muscle mass determines our metabolic rate so even if our body weight stays stable, our metabolic engine slows down as we lose muscle and it becomes harder to maintain that weight.
Secondly, there is some role with for hormonal changes, but this role is incompletely understood. With menopause we tend to store weight centrally in our bodies, which may be a hormonal effect.
Perhaps most importantly, life changes as we get older and our lifestyle and environment evolves. We may not realize how much these changes affect the amount of energy we burn as our environment become more sedentary and obesogenic.
I should also point out that it is harder for everyone in our society to avoid gaining weight, even for children. Increasing numbers of children and adolescents are overweight and fighting obesity.

MedicalResearch.com Interview with: Prof Mika Kivimäki PhD
Department of Epidemiology and Public Health,
University College London, London, UK
Hjelt Institute, Medical Faculty, University of Helsinki, Helsinki, Finland
Medical Research: What are the main findings of the study?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.

MedicalResearch.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. Philippe Courtet MD PhD
Centre Hospitalier Régional Universitaire de Montpellier, Institut National de la Santé et de la Récherche Médicale ,
Université Montpellier, Montpellier, France
Fondation Fondamental, Créteil, France
Medical Research: What are the main findings of the study?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.

Medical Research: What are the main findings of the study?Dr. Lee: We found that in our cross-sectional study of six inpatient units in five hospitals that, in general, only 11% of patients were wearing lower body garments despite the fact that probably 55% of them could have been doing so. The remainder were wearing open backed gowns. When specifically asked, the majority of these patients would like to have been afforded the opportunity to wear more dignified attire and the patients were surprised that they were allowed to do so.

MedicalResearch.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.
