Medical Research: What are the main findings of the study?Answer: This is one of the largest studies to date on the long-term outcomes of patients after aortic valve replacement. We found that bioprosthetic valves are as safe as mechanical valves in younger patients (age 50-69) - specifically, long-term death rates and stroke risk were very similar in patients who had either valve type. The main differences lay in the risk of other long-term complications: patients who had bioprosthetic valves were more likely to need repeat surgery in the long-term, whereas patients who had mechanical valves were more likely to experience a major bleeding event.

University of Arizona Medical Center
Medical Research: What are the main findings of the study?Dr. Klimentidis:The main finding is that the association of physical activity with type-2 diabetes risk is weakest among those who are at high genetic risk for type-2 diabetes. Furthermore, we find that this trend is stronger among women as compared to men, and that it appears to be driven mainly by genetic risk to insulin resistance, as opposed to genetic risk for reduced beta-cell function.

Medical University of Graz
8036 Graz, Austria
Medical Research: What are the main findings of the study?Dr. Amrein:This is the first large clinical trial on vitamin D in critical care. In a double-blind, randomized, placebo-controlled clinical trial, a population of mixed adult ICU patients with vitamin D deficiency (defined as 25-hydroxyvitamin D [25(OH)D] level ≤ 20ng/ml) was assigned to receive either vitamin D3 or placebo. We used a high loading dose of vitamin D3 followed by monthly maintenance doses of 90,000 IU for a total of 5 months. Because of a substantially increased risk for skeletal complications below 12ng/ml of 25-hydroxyvitamin D, we used this threshold for a predefined subgroup analysis.
Overall, high-dose vitamin D3 compared with placebo did not reduce hospital length of stay (primary endpoint), intensive care unit (ICU) length of stay, hospital mortality, or 6 month-mortality

Medical Research: What are the main findings of the study?Dr. Metcalf: This study investigated whether acupuncture is an effective treatment for people aged more than 50 years with chronic knee pain. Participants in our study were randomly assigned to one of four groups; needle acupuncture, laser acupuncture, sham laser acupuncture or no treatment. The people in the treatment groups received acupuncture treatment from a family physician for 12 weeks. Participants were assessed after treatment and again after one year.
There were no significant differences in knee pain or physical function between active and sham laser acupuncture at 12 weeks or at one year. Both needle and laser acupuncture resulted in modest improvements in pain compared with no treatment at 12 weeks that were not maintained at one year. Needle acupuncture improved physical function at 12 weeks compared with no treatment but was not different from sham acupuncture and was not maintained at one year.

MedicalResearch.com Interview with Megan A. Adams, MD
Gastroenterology Fellow
University of Michigan
Medical Research: What are the main findings of the study?Dr. Adams: Surveys of doctors indicate that their fear of a malpractice lawsuit for missing a diagnosis of esophageal cancer might drive the overuse of tests called upper endoscopies in patients who are at low risk for the cancer. To examine whether this perception of medical liability risk accurately reflects the real likelihood of a malpractice claim, we looked at a national database of malpractice claims, and compared the rate of claims for delay in diagnosis of esophageal cancer in patients without alarm symptoms (weight loss, dysphagia, iron deficiency anemia), with the rate of claims alleging performance of an upper endoscopy without a good reason for performing the procedure.
The database contained 278,220 claims filed against physicians in 1985-2012. The incidence of reported medical liability claims for failure to screen for esophageal cancer in patients without alarm features was quite low (19 claims in 11 years, 4 paid). In contrast, there were 17 claims in 28 years for complications of upper endoscopies with questionable indication (8 paid).

MedicalResearch.com Interview with:Lior Yankelson, MD PhD
Tel Aviv Medical CenterMedicalResearch: What are the main findings of the study?Dr. Yankelson:The main findings of the study are that new onset atrial fibrillation after TAVI does not confer a significant risk for mortality , and confers somewhat increased risk for stroke. The latter issue is expected to become less significant with new technological advancements coming into the market, such as lower profile devices and emboli protection both mechanical and pharmaceutical. The more significant and alarming finding is that patients with atrial fibrillation have more than 4 fold risk for death at 1 year post TAVI compared to patients without afib. This is very significant and raises questions regarding the benefit for the procedure in these patients.

Medical Research : What is the background for this study?Dr. Badri: Recent years witnessed increased emphasis of the role of clinical guidelines in cardiovascular care. Physicians are encouraged to practice within the framework of major society guidelines to deliver better, more cost-effective patient care. It is therefore vital that the recommendations in these guidelines are applicable to most of the patient population. Since some clinical trials have been shown in the past to unfavorably exclude women, racial minorities and elderly patients, we conducted this study to see if the clinical trials used to form the American College of Cardiology/American Heart Association adequately represent these patient groups.

MedicalResearch.com Interview with:Keren Lehavot, PhD
Research Clinical Psychologist
VA Puget Sound Health Care System
Assistant Professor
Department of Psychiatry & Behavioral Sciences
University of Washington
Medical Research: What are the main findings of the study?Dr. Lehavot:Alcohol misuse is a significant public health concern among women living in the U.S. Women who have served in the military are a unique population who report relatively high rates of hazardous drinking, and those who identify as lesbian or bisexual (LB) may be at especially high risk for alcohol misuse. While previous research suggests that lesbian or bisexual veterans report higher rates of alcohol misuse than their heterosexual counterparts, mediators that might explain this disparity have not been identified. To that end, we examined the role of civilian and military traumas and mental health symptoms (i.e., depression, post-traumatic stress disorder) in explaining disparities in alcohol misuse between sexual minority and heterosexual women veterans across the U.S. Women veterans were recruited using the Internet to participate in an online, anonymous, national survey.
Findings indicated that lesbian or bisexual veterans scored significantly higher on an alcohol misuse measure than heterosexual women veterans. LB veterans also reported higher rates of childhood trauma, physical victimization in adulthood both during the military and as a civilian, and mental health symptoms, partly accounting for their higher rates of alcohol misuse.

MedicalResearch.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.

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.

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.

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…)

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.
