Author Interviews, Exercise - Fitness / 30.10.2013

MedicalResearch.com Interview with: George Mammen, PhD Candidate Health & Exercise Psychology Unit University of Toronto MedicalResearch.com: What are the main findings of the study? Answer:
  • 25 out of the 30 studies found PA to protect against depression; majority of these were of high methodological quality
  • Decreasing PA overtime can increase the risk of developing depression; increasing PA overtime can reduce the risk of developing depression
  • In terms of dosage, the review highlighted studies that showed even low levels, such as 20 mins of walking a day, can prevent the onset of depression. (more…)

MedicalResearch.com Interview with: Lotta Ljung, MD, PhD Umeå University, Umeå and Karolinska  Institute Stockholm, Sweden MedicalResearch.com: What are the main findings of the study? Dr. Ljung:  In this observational study we observed a lower risk of acute coronary syndromes in a cohort of patients with rheumatoid arthritis (RA) exposed to tumor necrosis factor inhibitors (TNFi) compared with the risk among patients without this exposure. The adjusted relative risk (HR) was 0.73-0.82  among TNFi exposed patients compared with the biologics-naive RA cohort, depending on the time frame evaluated, which can be concluded as a moderately lower risk. Compared with the risk in the general population, the risk in RA patients was higher, whether exposed to TNFi or not. (more…)

MedicalResearch.com Interview with Dr. Ketil Stordal Researcher/consultant paediatrician National Institute of Public Health Norway MedicalResearch.com: What are the main findings of the study? Dr. Stordal: Mothers who used iron supplementation during pregnancy had an increased risk for having children with a diagnosis of celiac disease. This association was not caused by maternal anemia during pregnancy, anemia was not a predictor of celiac disease in the offspring. The risk for celiac disease when the mother had used the highest doses and for the longest period. (more…)

Lauren Block, MD Assistant Professor, North Shore–LIJ Hofstra School of Medicine 2001 Marcus Ave., Suite S160 Lake Success, NY 11042MedicalResearch.com Interview with: Lauren Block, MD Assistant Professor, North Shore–LIJ Hofstra School of Medicine 2001 Marcus Ave., Suite S160 Lake Success, NY 11042   MedicalResearch.com: What are the main findings of the study? Dr. Block: Our goal was to look at how often doctors in training were performing basic niceties with their patients, such as introducing themselves and sitting down. We found that while the doctors usually asked open-ended questions and touched patients, resident physicians were unlikely to introduce themselves, explain their role, or sit down when talking to patients.

MedicalResearch.com Interview with: Lorenz Raber, MD University Hospital Bern Bern, Switzerland

MedicalResearch.com: What are the main findings of the study? Dr. Raber: The main finding of the clinical study is that the benefit of a biolimus-eluting stent using a biodegradable polymer (Biomatrix, BES) regarding MACE (cardiac death, target vessel MI, TLR) continued to accrue during the second year of follow-up, actually with a similar relative risk reduction as observed during the first year. After one year, the timepoint at which most patients stopped dual antiplatelet therapy (DAPT), no difference in safety (cardiac death, myocardial infarction, stent thrombosis) was observed between BES and the control group (bare metal stent, BMS). This largely confirms the principle concept of biodegradable polymer stent platforms. The results of the imaging substudy provide a mechanistic explanation for the observed benefit with BES.  Specifically, BES showed a lower neointimal thickness, a low frequency of uncovered and malapposed stent struts  (OCT) and the absence of positive remodeling (IVUS) at 13 months follow-up.

Wong, MD MPH Community Interventions for Infection Control Unit Division of Global Migration & Quarantine Centers for Disease Control and Prevention MedicalResearch.com: What are the main findings of the study? Dr. Wong: There were 830 pediatric influenza-associated deaths reported to CDC during the 2004–2005 through 2011–2012 seasons; deaths occurred in children of all ages, and 43% had no high-risk medical conditions. Of children 6 months of age or older whose vaccination status was known, only 16% had been fully vaccinated with seasonal influenza vaccine. (more…)
Author Interviews, Diabetes, Mediterranean Diet, Memory / 24.10.2013

MedicalResearch.com Interview with: Lucia Kerti MA From the Departments of Neurology Charité–University Medicine, Berlin MedicalResearch.com: What are the main findings of the study? Answer: The results of our study on 141 healthy older people suggest that chronically higher blood glucose levels may have a negative influence on memory performance even in the absence of type 2 diabetes or even pre-diabetes. Moreover, our findings indicate that elevated blood glucose levels  impair the functioning of brain areas like the hippocampus, a structure particularly relevant for memory. An important novel aspect in our study was the additional analysis of diffusion tensor imaging-based mean diffusivity within the hippocampal, which allowed us to  obtain information on microstructure.  We here provided first-time data of an association between higher blood glucose levels and lower hippocampal microstructure. Decreased hippocampal microstructure as measured by mean diffusivity may reflect a disruption of neuronal membranes and increased extracellular water content, leading to decreased signaling within and between hippocampal cells. Thus, information transfer between cells, indispensable for memory encoding, storage and retrieval, would be compromised. In sum, our data suggest that chronically higher blood glucose levels even within the "normal range" may decrease memory functions, possibly in part mediated by microstructural changes within the hippocampus.

Alzheimer's - Dementia, Author Interviews / 24.10.2013

MedicalResearch.com Interview with: Andrew S. Lim MD MMSc FRCPC DABPN Assistant Professor and Clinician Scientist Division of Neurology, Department of Medicine Sunnybrook Health Sciences Centre University of Toronto MedicalResearch.com: What are the main findings of the study? Dr. Lim: Alzheimer disease (AD) is the result of a confluence of genetic, behavioral, and environmental risk factors.  The Apolipoprotein E (APOE) e4 allele is the most common and well established genetic risk factor for Alzheimer Disease.  10-20% of the US population carries the high risk APOE e4 allele, which confers up to a 30% lifetime risk of AD. Meanwhile, previous work had suggested that poor sleep may be a risk factor for AD and that APOE genotype and poor sleep may amplify each other's negative cognitive effects. We asked the question whether good sleep consolidation (i.e. sound sleep without repeated awakenings) may reduce the effect of APOE on the risk of incident AD and the burden of AD pathology.  We studied 698 individuals without dementia participating in the Rush Memory and Aging Project - a longitudinal cohort study of aging and risk factors for AD.  We measured sleep consolidation using wrist-watch like devices called actigraphs, and followed participants for up to 6 years, examining them annually for the development of AD.  Autopsies were perfumed on 201 participants who died during the follow-up period and we quantified the burden of AD pathology. During the follow-up period, 98 participants developed AD.  As expected, carrying the APOE e4 allele was associated with a higher risk of AD, faster cognitive decline, and a higher burden of AD pathology (amyloid plaques and neurofibrillary tangles) at death. However, better sleep at baseline significantly reduced the negative impact of APOE e4 on the risk of AD, rate of cognitive decline, and burden of neurofibrillary tangle pathology. (more…)

Meredith Atkinson, MD, MHS Assistant Professor of Pediatrics Division of Pediatric Nephrology Johns Hopkins University School of Medicine Baltimore, MD 21287 MedicalResearch.com Interview with: Meredith Atkinson, MD, MHS Assistant Professor of Pediatrics Division of Pediatric Nephrology Johns Hopkins University School of Medicine Baltimore, MD 21287   MedicalResearch.com: What are the main findings of the study? Dr. Atkinson: First, among a healthy cross-section of U.S. children, vitamin D deficiency defined as levels below 30 ng/mL (the currently accepted threshold for adequate vs. inadequate vitamin D) were associated with nearly twice the risk for anemia compared to those with sufficient vitamin D levels.  Secondly, when we looked specifically at Caucasian and African-American children, we found that children with the lowest vitamin D levels were at increased risk for anemia in both groups, but that the specific vitamin D level below which the anemia risk started to increase was much lower in the African-American children (12 ng/mL) than in the Caucasian children (20 mg/mL).

MedicalResearch.com Interview with: Stefanie Hägg, MB Folkhälsan Institute of Genetics, Folkhälsan Research Center, Biomedicum Helsinki Division of Nephrology, Department of Medicine, Helsinki University Central Hospital, Helsinki, Finland MedicalResearch.com: What are the main findings of the study? Answer: We studied the incidence of stroke in a large cohort of patients with type 1 diabetes in Finland. During 36,680 person-years of follow-up, we found that the incidence of total stroke, and the subtypes cerebral infarction and cerebral hemorrhage was 406, 286, and 120 per 100,000 person-years, respectively, which is higher than in the Finnish general population, for whom the incidence of stroke varies between 135 and 236 per 100,000 person years. Furthermore, we studied the impact of two diabetic microvascular complications, diabetic nephropathy and severe diabetic retinopathy, on the risk of stroke, as well as for the subtypes of stroke. The incidence of stroke, cerebral infarction, and cerebral hemorrhage increased with both the presence of severe diabetic retinopathy and with advancing diabetic nephropathy. Furthermore, we found that both diabetic nephropathy and severe diabetic retinopathy increased the risk for all subtypes of stroke, independently of traditional risk factors. A novel finding was that already incipient diabetic nephropathy (microalbuminuria) increased the risk of stroke, cerebral infarction, and cerebral hemorrhage more than 3-fold, compared with patients free of renal disease. The highest risk of stroke was seen in patients with end-stage renal disease. (more…)

David T Harris, Phd Department of Immunobiology University of Arizona PO Box 245221, Tucson, AZ 85724Medicalresearch.com Interview with: David T Harris, Phd Department of Immunobiology University of Arizona PO Box 245221, Tucson, AZ 85724. MedicalResearch.com: What are the main findings of the study? Dr. Harris: The primary finding of the study was that it was routinely possible to harvest left-over adipose tissue and stem cells from both liposuction and cosmetic procedures, cryopreserve it for prolonged periods of time, and then thaw the tissue later when needed.  Frozen and thawed adipose tissue was routinely viable and able to be differentiated into additional fat, as well as bone, cartilage and neuron-like cells.  Thus, one can bank adipose tissue and stem cells without first isolating the stem cells allowing one to use the frozen and thawed tissue at later times for both cosmetic applications as well as for regenerative medicine.

Author Interviews, Johns Hopkins, Sleep Disorders / 22.10.2013

MedicalResearch.com Interview with: Ruth Tamrat, Minh-Phuong Huynh-Le, and Madhav Goyal Johns Hopkins University School of Medicine, MSIV MedicalResearch.com: What are the main findings of the study? Answer: Despite the known adverse effects of sleep deprivation on recovery from illness, studies have shown that sleep deprivation remains an incompletely addressed problem among inpatients.  Behavioral interventions are recommended as first line therapy prior to using pharmacologic therapy due to the adverse side effects of sedative hypnotics. This systematic review sought to identify the efficacy of non-pharmacologic interventions that have been used to improve the sleep of general inpatients.  The results of this review demonstrate a lack of high quality evidence regarding the efficacy of these non-pharmacologic interventions in improving the sleep quality or quantity of patients in the hospital.

Dr. Gina Agarwal Assistant Professor Department of Family Medicine McMaster Family Practice 690 Main Street West Hamilton , Ontario L8S 1A4MedicalResearch.com Interview with: Dr. Gina Agarwal Assistant Professor Department of Family Medicine McMaster Family Practice 690 Main Street West Hamilton , Ontario L8S 1A4 MedicalResearch.com: What are the main findings of the study? Dr. Agarwal: The study findings are just preliminary as of yet, but suggest that the CHAP-EMS program is potentially a feasible and effective health program for seniors housing buildings in urban areas. The program delivered tailored health risk assesments to seniors living in subsidized city housing, also assessing their risk of cardiovascular disease, diabetes and falls using validated tools. Paramedics were trained in how to assess, and deliver risk assessment results and then provide community resource information. Seniors attending the program could drop in any time and were encouraged to come back for follow up sessions. Results of each attendance were forwarded to family doctors to close the loop. At the 5th month of implementation, we have recorded 241 participant visits by 40 unique participants; 37 had 2 or more visits; 70% had elevated BPs initially; 77.8% of those previously diagnosed hypertensive and 55.8% of those undiagnosed hypertensive had elevated BP; 82.5% had moderate to high CANRISK scores. Preliminary data shows a 32% reduction in EMS calls. (more…)

MedicalResearch.com Interview with Katherine Auger, MD, MSc Assistant Professor of Pediatrics Division of Hospital Medicine Cincinnati Children's Hospital Medical Center MedicalResearch.com: What are the main findings of the study? Dr. Auger: We examined hospitalization rates in infants for pertussis before versus after the recommendation to universally vaccinate all adolescents with Tdap.  We used mathematical modeling to predict the number of infant hospitalizations that would be expected without the Tdap vaccine policy.  We then compared these predicted numbers to the actual observed numbers of infant hospitalizations.  In 3 of the 4 years after Tdap vaccine policy, there were significantly fewer infant hospitalizations for pertussis than expected base on the predictions.

MedicalResearch.com Interview with: Sharon Curhan, MD, ScM Channing Division of Network Medicine Brigham and Women's Hospital Harvard Medical School Boston, MA 02115 MedicalResearch.com: What are the main findings of the study? Dr. Curhan: The main findings of our study are that higher body mass index and larger waist circumference are associated with an increased risk of acquired hearing loss, and higher level of physical activity is associated with a decreased risk of acquired hearing loss in women. Specifically, after adjusting for potential confounders, compared with women with BMI <25 kg/m2, the relative risk for hearing loss was 25% higher for women with BMI >40. Compared with women with waist circumference <71 cm, the relative risk for hearing loss was 27% higher for women with waist circumference >88 cm. Higher physical activity was inversely related to risk; compared with women in the lowest quintile of physical activity, women in the highest quintile of physical activity had a 17% lower risk of hearing loss. Walking, the most common form of physical activity among these women, was associated with a lower risk; women who walked 2 hours per week or more had a 15% lower risk of hearing loss than women who walked less than one hour per week. These findings provide evidence that maintaining healthy weight and staying physically active, potentially modifiable lifestyle factors, may help reduce the risk of hearing loss. (more…)

kees_jan_kanMedicalResearch.com Interview with Dr. Kees-Jan Kan PhD Department of Biological Psychology, VU University Department of Psychological Methods, University of Amsterdam MedicalResearch.com: What are the main findings of the study? Answer: We asked ourselves how well theories of intelligence actually predict empirical results. To this end, we reviewed and scrutinized the predictions from intelligence theories and collected relevant results that have been published in the scientific literature over the last decades. The results pertained to intelligence test scores from thousands of subjects across the world. We found that on essential aspects the empirical results were opposite of the predictions from the mainstream theories of intelligence, in which intelligence is interpreted as a biological trait.

Saul Blecker, MD, MHS Department of Population Health, NYU School of Medicine, New York, NY Department of Medicine, NYU School of Medicine, New York, NYMedicalResearch.com Interview with: Saul Blecker, MD, MHS Department of Population Health, NYU School of Medicine Department of Medicine, NYU School of Medicine, New York, NY   MedicalResearch.com: What are the main findings of the study? Dr. Blecker: Inpatient quality of care has focused primarily on patients with acute heart failure, commonly identified by principal discharge diagnosis code. However, patients with heart failure are commonly hospitalized for other causes and should benefit from many of the same treatments. We found that in our sample, as compared to patients with a principal diagnosis of heart failure, heart failure patients hospitalized with a non–heart failure diagnosis had lower rates of guideline-concordant care, including assessment of left ventricular function and prescription for an ACE inhibitor or ARB, at time of discharge. This is important as our study suggests that these therapies were associated with reduced mortality for patients hospitalized with heart failure, regardless of the reason for hospitalization. (more…)

Answer: We found in this sample of relatively young, Finnish twins that there are clearly two different kinds of obesity. While most individuals with BMIs in the "obese" category will go on to develop the usual pathologies associated with obesity (namely diabetes, hypertensio, dyslipidemia), a fraction of the obese population seems to be spared. These "metabolically healthy obese" individuals displayed a number of features that were associated with a healthy metabolic profile despite considerable overweight: a capacity for hyperplasia of the adipose tissue (as opposed to just hypertrophy) seemed to be associated with maintained mitochondrial function, lack of inflammation and liver fat.

MedicalResearch.com Interview with Stephan  Zipfel  MD Professor of Medicine & Dean of Medical Education Head Department of Internal Medicine VI (Psychosomatic Medicine and Psychotherapy) University Medical Hospital Tuebingen President of the German College of Psychosomatic Medicine (DKPM) Co-Director of the centre for nutritional Medicine Tuebingen-Hohenheim 72076 Tuebingen / Germany MedicalResearch.com: What are the main findings of the study? Prof. Zipfel: Outpatient treatment of adults with anorexia nervosa by either enhanced cognitive-behaviour therapy, focal psychodynamic therapy, or optimised treatment as usual led to relevant weight gains and a decrease in general and eating disorder-specific psychopathology during the course of treatment. These positive effects continued beyond treatment until 12-month follow-up. Most patients completed treatment and the acceptance of both specific therapy approaches was high among both patients and therapists. (more…)

Dr. Aagaard: We obtained feedback on, and assessed the construct validity and perceived feasibility and utility of, draft Internal Medicine Milestones for Patient Care and Systems-Based Practice used a mixed methods  study involving competency committee members in Internal Medicine residency programs. An initial survey assessed participant and program demographics; focus groups obtained feedback on the draft milestones and explored their perceived utility in resident assessment, and an exit survey elicited input on the value of the draft milestones in resident assessment. Thirty-four participants from 17 programs completed surveys and participated in 1 of 6 focus groups. Overall, the milestones were perceived as useful in formative and summative assessment of residents. Participants raised concerns about the length and complexity of some draft milestones and suggested specific changes. The focus groups also identified a need for faculty development. In the exit survey, most participants agreed that the Patient Care and Systems-Based Practice Milestones would help competency committees assess trainee progress toward independent practice. (more…)

Kesava Reddy, PhD, MHA University Cancer and Diagnostic Centers, Houston, TexMedicalResearch.com  interview with: Kesava Reddy, PhD, MHA University Cancer and Diagnostic Centers, Houston, Tex     MedicalResearch.com: What are the main findings of the study? Dr. Reddy: Crude oil spills affect the human health through their exposure to the inherent hazardous chemicals such as para-phenols and volatile benzene. Evidence show that oil spill exposure is associated with multiple adverse health effects and increased cancer risk. In this study, we assessed the adverse health effects of the Gulf oil spill exposure in subjects participating in the clean-up operation along the coast of Louisiana. The findings were compared with those not exposed to the oil spill. We found that platelet counts were notably decreased in the oil spill exposed group. In addition, creatinine and blood urea nitrogen levels were substantially lower in the exposed group, while hemoglobin and hematocrit levels were increased compared to the unexposed subjects. Furthermore, considered indicators of hepatic damage, the serum alkaline phosphatase (ALP), aspartate amino transferase (AST), alanine amino transferase (ALT), levels in the exposed subjects were also elevated. Participants  in the oil spill cleanup activity also reported somatic symptoms, with headache reported most frequently, followed by shortness of breath, skin rash, cough, dizzy spells, fatigue, painful joints, night sweats, and chest pain.

Strahlenhygiene 85764 NeuherbergMedicalResearch.com: Prof. Dr. Gunnar Brix Division of Medical and Occupational Radiation Protection Federal Office for Radiation Protection Institut für Med. Strahlenhygiene 85764 Neuherberg MedicalResearch.com:  What are the main findings of the study? Answer: We investigated the cumulative radiation exposure and cancer risk of more than 1200 patients with ischemic heart diseases (IHD) from diagnostic and therapeutic imaging procedures performed 3 month before and 12 month after the date of diagnosis. The major findings were:
  • ­    87% of patient exposure resulted from heart catheter procedures.
  • ­    The average cumulative effective dose was 13.3 mSv in males and 10.3 mSv in females. The highest dose was nearly 100 mSv.
  • ­    The estimated average attributable life-time risk of male and female patients to develop a radiation-induced cancer in their remaining life was 0.09 % and  0.07 %, respectively. This correspond to 1 excess cancer in about 1100 male and 1400 female IHD patients. The highest risk was 0.9 %.
  • ­ The effective dose is inadequate to characterize individual radiation risks, since neither the age nor the sex of the patient is taken into account. According to our results, cancer risks can vary by a factor of more than 10 for comparable values of the effective dose. (more…)
