Manesh Patel, MD Associate Professor of Medicine Director Interventional Cardiology and Catheterization Labs Duke University Health System Duke Clinical Research InstituteMedicalResearch.com Interview with: Manesh Patel, MD Associate Professor of Medicine Director Interventional Cardiology and Catheterization Labs Duke University Health System Duke Clinical Research Institute Medical Research: What is the background for this study? What are the main findings? Dr. Patel: In clinical practice, patients with acute myocardial infarction are found to have non-IRA disease of varying significant and location.  The current recommendations are to have patients recover from the acute myocardial infarction and get non-invasive testing to determine revascualrization after 4-6 six weeks in uncomplicated patients.  These data demonstrate that non-IRA disease is common (>50% of STEMI patients) and that these patients have an elevated 30-day mortality.

MedicalResearch.com Interview with: Charles Tzu Chi Lee, PhD Associate Prof., Department of Public Health Kaohsiung Medical University, Kaohsiung, Taiwan Sanmin District, Kaohsiung City Taiwan Medical Research: What is the background for this study? What are the main findings? Dr. Lee: Amyotrophic lateral sclerosis (ALS) is a progressive neurodegenerative disease and most patients die within three to five years after symptoms appear. Studies have suggested angiotensin-converting enzyme inhibitors (ACEIs) may decrease the risk for developing neurodegenerative diseases. But there was still no human study discussing ACEIs use and ALS risk in literature. The study results indicate that when compared with patients who did not use ACEIs, the risk reduction was 17 percent (adjusted odds ratio of 0.83) for the group prescribed ACEIs lower than 449.5 cumulative defined daily dose (cDDD) and 57 percent (adjusted odds ratio 0.43) for the group prescribed ACEIs greater than 449.5 cDDD.

Elyse O. Kharbanda MD MPH HealthPartners Medical and Dental GroupMedicalResearch.com Interview Elyse O. Kharbanda MD MPH HealthPartners Medical and Dental Group Medical Research: What is the background for this study? What are the main findings? Dr. Kharbanda: In 2010, due to a pertussis outbreak and neonatal deaths, the California Department of Public Health recommended that the Tdap vaccine be administered during pregnancy.  Tdap is now recommended by the Advisory Committee on Immunization Practices (ACIP) for all pregnant women during each pregnancy.  We wanted to assess the impact of this recommendation. The main findings were that Tdap vaccination during pregnancy was not associated with increased risk for hypertensive disorders of pregnancy, preterm birth, or having a baby who is small for his or her gestational age. The study found a small increased risk for being diagnosed with chorioamnionitis, an inflammation of the fetal membranes caused by bacterial infection.  These findings should be interpreted with caution as the magnitude of the risk was small.  In addition, there was no associated risk for preterm birth, which often occurs as a result of chorioamnionitis.  Furthermore, among the subset of women with a chorioamnionitis diagnosis whose charts were reviewed, many did not have a clinical picture that was clearly consistent with chorioamnionitis.

What are the main findings? Ms. Bhak: Abdominal aortic aneurysms (AAA) and their rupture are potentially fatal, so monitoring and understanding their expansion is of utmost importance. This study sought to characterize factors associated with Abdominal aortic aneurysms expansion, as well as their different growth patterns. The main findings are that current smoking and diastolic blood pressure are associated with increased linear expansion rate, diabetes with a decreased linear expansion rate, and diastolic blood pressure and baseline abdominal aortic aneurysms diameter with an accelerated expansion rate.

Dr. Adriaan J van der Meer Department of Gastroenterology and Hepatology Erasmus MC, University Medical Center Rotterdam, The NetherlandsMedicalResearch.com Interview with: Adriaan J. van der Meer, MD, PhD Department of Gastroenterology and Hepatology Erasmus MC University Medical Center Rotterdam, Rotterdam, the Netherlands Medical Research: What is the background for this study? What are the main findings? Dr. van der Meer: This study was performed in order to assess the association between the virological response to antiviral therapy and the long-term clinical outcome among patients with advanced liver disease, who have the highest risk of cirrhosis-related complications and death due to their chronic viral infection. At the time this study was initiated there was scarce data on the relation between a sustained virological response (SVR; sustained elimination of hepatitis C RNA) and reduced all-cause mortality, the most definite clinical endpoint. With our large international multicenter cohort study we were able to show this association. After 10 years of follow-up the cumulative mortality rate was 9% among patients with SVR as compared to 26% among patients without SVR after antiviral therapy (p<0.001). The current JAMA research letter concerns a related analyses, in which we compared the survival among patients included in our cohort with that of an age- and sex-matched general population. Importantly, the survival among patients with SVR was comparable to the general population, despite the fact that all these patients had histological proof of advanced hepatic fibrosis. In contrast, the survival among patients without SVR was markedly lower as compared to the general population. (more…)

Ziad Obermeyer, MD, MPhil Emergency Medicine, Brigham & Women's Hospital Assistant Professor, Harvard Medical SchoolMedicalResearch.com Interview with: Ziad Obermeyer, MD, MPhil Emergency Medicine, Brigham & Women's Hospital Assistant Professor, Harvard Medical School Medical Research: What is the background for this study? What are the main findings? Dr. Obermeyer: More patients with cancer use hospice today than ever before, but there are indications that care intensity outside of hospice is increasing, and length of hospice stay decreasing. We examined how hospice affects health care utilization and costs and found that, in a sample of elderly Medicare patients with advanced cancer, hospice care was associated with significantly lower rates of both health care utilization and total costs during the last year of life. Patients who did not enroll in hospice had considerably more aggressive care in their last year of life—most of it related to acute complications like infections and organ failure, and not directly related to cancer-directed treatment. Hospice and non-hospice patients had similar patterns of health care utilization until the week of hospice enrollment, when care began to diverge. Ultimately, non-hospice patients were five times more likely to die in hospitals and nursing homes. These differences in care contributed to a statistically-significant difference in total costs of $8,697 over the last year of life ($71,517 for non-hospice and $62,819 for hospice).

MedicalResearch.com Interview with: Brendan J. Perry, BSc, MBBS Princess Alexandra Hospital Brisbane, Queensland, Australia MedicalResearch: What is the background for this study? What are the main findings? Dr. Brendan J. Perry: Oral cavity cancer is usually attributed to the “Five S’s” - smoking, spirits (alcohol), spices, syphillis and sharp (or septic) teeth. Cigarettes and alcohol are the most important recognised factors. Spices, such as betel nut, and syphillis are known carcinogens but are not commonly seen in western practice. The role of chronic dental trauma on the mucosa of the mouth to cause cancer has only been examined in a limited number of studies previously and its importance has not been elucidated and has never really affected clinical practice. This retrospective review examined the position in the oral cavity where cancers occurred with respects to smoking status and other variables over a 10 year period in a major Australian hospital. The edge of the tongue, a site of potential dental trauma, was the most common site affected, accounting for 35% of oral cavity cancers in smokers. However, in lifelong non-smokers without other significant risk factors, 65% of cancers occurred on the edge of the tongue. A significant number also occurred on the buccal mucosa (inner lining of cheek) which is also exposed to dental trauma, but to a much lesser degree than the more mobile tongue. The floor of the mouth and the alveolar ridge (gums) were also common sites of cancer, but tended to occur in an older age group. This is possibly due to irritation caused by the movement of dentures in this age group against these areas of the mouth. In recent years, dentists have been recommending clients to get removable denture nyc to tackle down on discomfort. We also found that males had an equal chance of developing oral cavity versus oropharyngeal cancer (255 cases vs 265). However, females are almost twice as likely to develop an oral cavity cancer than an oropharyngeal cancer (135 cases vs 69), and this ratio jumps to 4 times the risk for lifelong non-smoking females (53 vs 12). Although a lot of attention has been given to HPV in causing oropharyngeal cancer, for non-smokers, especially females, it appears that oral cavity cancer is a more common disease, and also that chronic dental trauma may be a significant contributing factor.

Author Interviews, JAMA, Metabolic Syndrome, Weight Research / 07.11.2014

MedicalResearch.com Interview with: Venkatesh L. Murthy, MD, PhD Department of Medicine (Cardiovascular Medicine Division) and Department of Radiology (Nuclear Medicine and Cardiothoracic Imaging Divisions), University of Michigan, Ann Arbor, Michigan and Dr. Ravi Shah MD Cardiology Division, Department of Medicine Massachusetts General Hospital, Boston, Massachusetts Medical Research: What is the background for this study? What are the main findings? Response: Prior studies in Framingham, MESA and other cohorts have demonstrated that obesity is an important risk factor for the metabolic syndrome. However, the observations that many non-obese individuals develop metabolic syndrome and diabetes and, conversely, that not all obese individuals develop these complications has motivated the search for better markers of risk than BMI. More recently, it has been shown that the location of adipose tissue is an important factor. The amount of visceral fat, which is thought to be more harmful from a metabolic perspective, can be accurately quantified with CT imaging. In many prior studies, waist circumference has been used as an approximate measure of visceral adiposity. For this study, we analyzed data from the Multi-Ethnic Study of Atherosclerosis (MESA). We found that the amount of visceral fat (as quantified by CT) was an important predictor of metabolic syndrome, even after adjusting for weight, waist circumference, gender, race, smoking, exercise, serum lipids and glucose. Each additional 100 cm2/m of height of visceral fat was associated with a 29% increase in the risk of developing metabolic syndrome. In contrast, subcutaneous fat burden (also quantified by CT) was a much weaker predictor. One of the very novel findings of our study arises from an analysis of subjects who had multiple CTs longitudinally in MESA. Using these data, we found that change in visceral fat burden was associated with a corresponding 5% increase in the risk of metabolic syndrome. In part, this is because very small changes in weight could result in very large changes in visceral fat. (more…)

Thomas M. Maddox MD MSc Cardiology, VA Eastern Colorado Health Care System Associate Director, VA CART ProgramMedicalResearch.com Interview with: Thomas M. Maddox MD MSc Cardiology, VA Eastern Colorado Health Care System Associate Director, VA CART Program Associate Professor, Department of Medicine University of Colorado School of Medicine Medical Research: What is the background for this study? What are the main findings? Dr. Maddox: Nonobstructive coronary artery disease (CAD) is atherosclerotic plaque that would not be expected to obstruct blood flow or result in anginal symptoms (such as chest pain). Although such lesions are relatively common, occurring in 10 percent to 25 percent of patients undergoing coronary angiography, their presence has been characterized as “insignificant” or “no significant CAD" in the medical literature.  However, this perception of nonobstructive coronary artery disease may be incorrect, because prior studies have noted that the majority of plaque ruptures and resultant myocardial infarctions (MIs; heart attacks) arise from nonobstructive plaques. Despite the prevalence of nonobstructive CAD identified by coronary angiography, little is known about its risk of adverse outcomes, according to background information in the article. During the study period, 37,674 patients underwent elective coronary angiography for indications related to CAD; of those, 22.3 percent had nonobstructive CAD and 55.4 percent had obstructive CAD.  Within 1 year, 845 patients died and 385 were rehospitalized for myocardial infarction. The researchers found that the 1-year myocardial infarction risk progressively increased by the extent of coronary artery disease, rather than abruptly increasing between nonobstructive and obstructive CAD.  Patients with nonobstructive CAD had an associated risk of MI that was 2-to 4.5-fold greater than among those with no apparent coronary artery disease. Similar observations were seen with 1-year mortality and the combined outcome of 1-year myocardial infarction and death. (more…)

Response: The Healthy Eating, Aerobic and Resistance Training in Youth study examined the effects of exercise on body composition and cardiometabolic risk markers in adolescents with obesity. A total of 304 overweight or obese adolescents were randomized to four groups. The first group performed resistance training involving weight machines and some free weights; the second performed only aerobic exercise on treadmills, elliptical machines and stationary bikes; the third underwent combined aerobic and resistance training; and the last group did no exercise training. All four groups received nutritional counseling. In analyses involving all participants regardless of adherence, each exercise program reduced percent body fat, waist circumference and body mass index to a similar extent, while the diet-only control group had no changes in these variables. In participants who exercised at least 2.8 times per week, we found that combined aerobic and resistance training produced greater decreases in percentage body fat, waist circumference, and body mass index than aerobic training alone. Waist circumference decreased close to seven centimeters in adherent participants randomized to combined aerobic plus resistance exercise, versus about four centimeters in those randomized to do just one type of exercise, with no change in those randomized to diet alone.

dr_stefan_hansenMedicalResearch.com Interview with: Stefan Nygaard Hansen PhD Student, MSc Stat Section for Biostatistics Department of Public Health Aarhus University Denmark Medical Research: What are the main findings of the study? Response: The main finding of our study is that 60% of the observed increase in autism prevalence among children born 1980-1991 in Denmark can be explained by changes in the way diagnoses are established and changes in the subsequent registration to national health registries. In 1994, the diagnostic criteria used by clinicians to establish psychiatric diagnoses was changed. This meant the recognition of autism as a spectrum of disorders but it also meant changes in the specific symptoms that form the basis of the autism diagnosis. In 1995, the national health registries in Denmark, which are often used in Danish health research, began to also include diagnoses given in connection with outpatient consultations whereas before 1995 only diagnoses given in connection with hospitalization was reported to the registries. This could mean that we after 1995 see more of the mild autism diagnoses since they may not require hospitalization. (more…)

Elgar, PhD Associate Professor of Psychiatry Canada Research Chair in Social Inequalities in Child Health Institute for Health and Social Policy, McGill University Montreal, Quebec, Canada Medical Research: What are the main findings of the study? Dr. Elgar: Our study addressed two questions. The first was whether cyberbullying has unique links to adolescent mental health, or is an extension of traditional (face-to-face) bullying. We measured various forms of bullying and found that cyberbullying does indeed have a unique impact on mental health. Our second question about protective factors in the home environment.  We examined the frequency of family dinners as potential a moderating factor - understanding, of course, that dinners are a proxy of various family characteristics that benefit adolescents, such as communication, support, and parental monitoring. We found that teens who were targeted by cyberbullying but had ate dinner with their families more often had significantly better mental health outcomes as a result. (more…)

What are the main findings? Dr. Thanassoulis: Although LDL-C (i.e. bad cholesterol) has been linked with aortic valve disease in several prior reports, randomized trials to lower cholesterol in aortic valve disease were not effective suggesting that cholesterol may not be important in valve disease. To address this, we performed a Mendelian randomization study, that showed that a genetic predisposition to LDL-C, was associated with both calcium deposits on the aortic valve and aortic stenosis (I.e. Valve narrowing).  These results can be viewed as the effect of a life-long increase in LDL-C on the incidence of aortic valve disease and suggest that increases in LDL-C cause aortic stenosis.   (more…)

Dr. Schmidt: We reviewed currently available policies for aligning cost and quality of care. We focused on interventions are similar in their clinical effectiveness, have modest differences in convenience, but pose substantial cost differences to the healthcare system and patients. To control health care costs while ensuring patient convenience and physician burden, reference pricing would be the most desirable policy. But it is currently politically unfeasible. Alternatives therefore need to be explored. We propose the novel concept of Inclusive Shared Savings, in which physicians, the healthcare system, and, crucially, patients, benefit financially in moving more patients to lower cost but guideline concordant and therapeutically equivalent interventions.

Marie C. Leger, MD, PhD Ronald O. Perelman Department of Dermatology New York University School of Medicine, New YorkMedicalResearch.com Interview with Marie C. Leger, MD, PhD Ronald O. Perelman Department of Dermatology New York University School of Medicine, New York Medical Research: What are the main findings of the study?
What was most surprising about the results?

 Dr. Leger: Alopecia areata is a T-cell mediated autoimmune disease. As such, there was initially hope that inhibiting the helper T cell cytokine TNF-α could effectively treat this condition. This has not been shown to be the case—in fact, one open-label study of etanercept in 17 patients with moderate to severe alopecia showed no hair regrowth and even worsening of alopecia in several subjects. There have been many other case reports in the dermatologic literature of TNF-α inhibitors causing alopecia areata. In contrast, our case report presents a patient who very clearly grew hair on adalimumab—its strength lies in the fact that her hair loss and regrowth were replicated on withdrawal and rechallenge with the medication. Our patient’s paradoxical response to adalimumab complements other literature suggesting that there are genetic variations in the way a patient’s immune system responds to TNF-α inhibitors. In different individuals, these medications can either treat or cause conditions such as psoriasis or lupus. It seems that this is also the case with alopecia areata. (more…)

Professor of Medicine Director, Transplant ID Program University of Nebraska Nebraska Medical Center Omaha, NE 68198-5400 Medical Research: What are the main findings of the study? Dr. Kalil: In recent years, physicians treating staph infections with vancomycin have seen an increase in the minimum inhibitory concentration (MIC), the lowest concentration of an antimicrobial agent that inhibits the growth of a microorganism. This condition is referred to as vancomycin “MIC creep.” It is an indicator that the bacteria might be developing a reduced susceptibility to vancomycin. There also have been reports suggesting that elevations in vancomycin MIC values may be associated with increased treatment failure and death. To determine the effectiveness of vancomycin and other newer antibiotics used to treat Staphylococcus aureus, the UNMC team analyzed nearly 8,300 episodes of Staphylococcus aureus bloodstream infections from patients around the U.S. and in several other countries. The adjusted absolute risk of mortality among patients with Staphylococcus aureus bloodstream infections with high-vancomycin MIC was not statistically different from patients with Staphylococcus aureus bloodstream infections with low-vancomycin MIC.

Dr. Spanier: Bisphenol A (BPA) is a chemical that is present in many consumer products (lining of canned foods, some plastics, some receipt paper, etc). We found that higher maternal Bisphenol A levels during pregnancy were associated with increased odds of persistent wheezing in children and a decrease in lung function at age four. Child BPA levels were not associated with these poor lung health outcomes. (more…)
