MedicalResearch.com Interview Ma, Wei Department of Epidemiology and Health Statistics School of Public Health Shandong University Jinan, Shandong Province, 250012 China MedicalResearch.com: What are the main findings of the study? Answer: The results of this meta-analysis suggested that there was an inverse dose-response association between levels of recreational physical activity and risk of hypertension. Individuals who participated in high levels of recreational physical activity had a 19% lower risk of hypertension than those who didn’t exercise much. In addition, those with moderate levels of recreational physical activity had an 11% lower risk of hypertension. However, there was no significant association between occupational physical activity and risk of hypertension. (more…)

MedicalResearch.com Interview with: Dr. Muy-Teck Teh BSc, PhD Centre for Clinical and Diagnostic Oral Sciences, Institute of Dentistry Barts & The London School of Medicine and Dentistry Queen Mary University of London, England, United Kingdom MedicalResearch.com: What are the main findings of the study? Answer: We found unique DNA markings (epigenetic methylation) on certain genes that may “predict” the risk of developing head and neck cancer. We identified certain DNA methylation marks unique to cancer cells and not found in normal healthy cells. DNA methylation marks act as ‘switches’ that regulate the ‘on or off’ statuses of genes. Abnormal DNA methylation is known to precede cancer initiation. Hence, the presence of these abnormal DNA methylation marks in cells may be tell-tale signs of early cancer initiation. The chemically distinctive properties of methylated DNA provide ample opportunities for clinical exploitation as nucleic acid-based biomarkers potentially detectable in non-invasive samples such as blood, buccal scrapes, or even saliva.

Author Interviews, Menopause, University of Pennsylvania / 03.10.2013

MedicalResearch.com Interview with: Katherine Newton, PhD Senior Investigator at Group Health Research Institute in Seattle MedicalResearch.com: What are the main findings of the study? Answer: We found that when women took a 12-week yoga class and practiced yoga at home, they had significantly less insomnia than did women who did not. This was the only statistically significant finding in this MsFLASH (Menopause Strategies: Finding Lasting Answers for Symptoms and Health) Network randomized controlled trial. We also found that being in the yoga class did not decrease the number of hot flashes or night sweats. Yoga  was linked to better sleep quality and less depression—but  these effects were not statistically significant. In separate papers, published slightly earlier, our MsFLASH group reported that a non-yoga exercise program seemed linked to slightly improved sleep and less insomnia and depression—but these effects were not statistically significant. And an omega-3 (fish oil) supplement was not linked to any improvement in hot flashes, night sweats, sleep, or mood.   (more…)
Alzheimer's - Dementia, Author Interviews / 03.10.2013

MedicalResearch.com Interview with: Keiichi Yamamoto, MD, PhD Department of Geriatric Medicine and Neurology, Osaka City University Graduate School of Medicine Osaka, Japan. MedicalResearch.com: What are the main findings of the study? Answer: Aβ is normally bound to and transported by albumin in blood. We therefore hypothesized that decreased blood levels of Albumin-Aβ complexes may be associated with decreased Aβ removal from brain to blood, resulting in Aβ accumulation in the brain. This is the first study demonstrated that decreased serum level of albumin-Aβ complexes was strongly associated with a higher prevalence of Alzheimer’s disease (AD). This association was independent of age, sex, and ApoE4 allele. In addition, decreased serum level of albumin-Aβ complexes was correlated with decreased levels of Aβ42 in the CSF and increased levels of p-tau in the CSF, findings that have been shown to be associated with specific neuropathologic findings and AD progression.

 Shaon Sengupta, MD MBBS MPH Division of Neonatology, Department of Pediatrics Children’s Hospital of Philadelphia, Philadelphia, PennsylvaniaMedicalResearch.com Interview with: Shaon Sengupta, MD MBBS MPH Division of Neonatology, Department of Pediatrics Children’s Hospital of Philadelphia, Philadelphia, Pennsylvania MedicalResearch.com: What are the main findings of the study? Dr. Sengupta: In this study we looked at all full-term neonates, which are defined as those born between 37 weeks 0 days to 41 weeks 6 days. Early term deliveries (37–38 weeks) are a significant part of all full-term deliveries, but are not the norm. In our study, 27% of neonates were born early term (37-38 weeks) while almost 62% were born at or after 39 weeks (term neonates). Similar data has been reported by other established sources of vital statistics. While traditionally, full term neonates are perceived to be a homogenous low-risk group, the findings from our study urge the pediatrics/neonatal provider to recognize early term (37-38 weeks) neonates as a higher risk group. They have significantly higher risk of NICU admission, respiratory morbidity, hypoglycemia, need for IV fluids and antibiotics. (more…)

Agnieszka Anna Tymula Lecturer (Assistant Professor) School of Economics The University of Sydney NSW 2006, AustraliaMedicalResearch.com Interview with: Agnieszka Anna Tymula Lecturer (Assistant Professor) School of Economics The University of Sydney NSW 2006, Australia MedicalResearch.com: What are the main findings of the study? Answer: We found that individual risk preferences as well as consistency and rationality in choice change with age. Just like cognitive abilities, the ability to make consistent and rational decisions considerably declines in older adulthood. Tolerance to risk in the domain of gains follows an inverted U-shaped pattern along the life span, with older adults (65+ y. o.) and adolescents being more risk averse than young or midlife adults. Interestingly, in the domain of losses, older adults are willing to accept significantly more risks than adolescents, young and midlife adults. (more…)

Marrion, PhD Professor of Neuroscience Programme Director for BSc and MSci Pharmacology degrees School of Physiology & Pharmacology Medical and Veterinary Sciences University Walk University of Bristol Bristol, BS8 1TD. MedicalResearch.com: What are the main findings of the study? Dr. Marrion: We tested pravastatin and atorvostatin (two commonly prescribed statins) in rat learning and memory models.  Rats were treated daily with pravastatin (brand name - Pravachol) or atorvostatin (brand name - Lipitor) for 18 days. The rodents were tested in a simple learning task before, during and after treatment, where they had to learn where to find a food reward. On the last day of treatment and following one week withdrawal, the rats were also tested in a task which measures their ability to recognise a previously encountered object (recognition memory). The study’s findings showed that pravastatin tended to impair learning over the last few days of treatment although this effect was fully reversed once treatment ceased. However, in the novel object discrimination task, pravastatin impaired object recognition memory.  While no effects were observed for atorvostatin in either task. (more…)

Dr. Afshin Farzaneh-Far, M.D. University of Illinois at ChicagoMedicalResearch.com Interview with: Dr. Afshin Farzaneh-Far, M.D. University of Illinois at Chicago MedicalResearch.com: What are the main findings of the study? Answer: Traditionally SPECT MPI has been performed with adenosine which has a significant body of published prognostic data. Regadenoson is a selective A2A receptor agonist and is now the stress agent most widely used in the United States. Unlike adenosine, regadenoson is given as a bolus rather than as an infusion, simplifying the testing protocol and is better-tolerated. However, despite increasing use of regadenoson, there is very limited data on risk prediction using this agent. This study showed that the ability of SPECT MPI to predict heart attacks and death is the same for the new stress agent Regadenoson as it is for the old agent Adenosine. (more…)

Dr. Bristow: We studied the more than 7 years of outcome of close to 250 patients with localized (intermediate risk) prostate cancer that received precision radiotherapy or surgery for cure. We found that up to one third of these patients fail initial radiotherapy or prostate surgery. By using a patient’s initial diagnostic core biopsy, we studied the DNA fingerprints of the tumors. We noticed a pattern in which the patients that had failed treatment had abnormal levels of breaks at sites within the chromosomes that are sensitive to DNA damage called, “common fragile sites” (CFS). These CFS break abnormalities have been linked to cancer in general and usually are associated with instability of the cell’s DNA-a phenomenon that is particularly associated with cancer. So patients who have unstable chromosomes are more likely to fail precision radiotherapy or surgery. (more…)

MedicalResearch.com Interview with: David W. Eyre, B.M., B.Ch. Nuffield Department of Clinical Medicine University of Oxford National Institute for Health Research (NIHR) Oxford Biomedical Research Centre John Radcliffe Hospital MedicalResearch.com: What are the main findings of this study? Dr. Eyre: All cases of Clostridium difficile in Oxfordshire were studied over 3 years. Isolates were characterized by whole genome sequencing and the data was linked to hospital databases allowing epidemiological relationships between patients at the level of the hospital ward, hospital specialty, and post code to be identified. For comparison, similar information was also available for all other patients with and without diarrhea.  Preliminary work on the genetic diversity of Clostridium difficile within individuals and between individuals within discrete outbreaks allowed reliable interpretation of transmission events using genomic data. This allowed a complete reconstruction of the pattern of transmission between affected cases in Oxfordshire to be made. The findings were: 1. Unexpectedly few cases (13%) appear to be acquired from direct ward based contact with other symptomatic cases (these have previously been thought to be the main source of infections, and the focus of prevention efforts). Another 6% were associated with other hospital contact and 3% had plausible community contacts. 2. In 13% of cases potential donors were identified gnomically but no contact, within hospitals or the community, were identified. This suggests that the existence of other modes of transmission of Clostridium difficile. 3. The sources of Clostridium difficile infections were highly genetically diverse, with 45% of cases having a genetically distinct origin - suggesting a diverse reservoir of disease, not previously appreciated 4. During the 3 years of the study the rate of Clostridium difficile in Oxfordshire fell.  Any improvement in infection control techniques would be expected to reduce the incidence of cases caused by within hospital transmission. Surprisingly, similar rates of fall occurred in both in secondary cases (considered to be acquired from hospital associated symptomatic cases) and for primary cases (cases not associated with transmission from symptomatic cases).

MedicalResearch.com Interview with: Krishna Patel, M.S. Clinical Data Analyst Hartford Hospital|Institute of Living Olin Neuropsychiatry Research Center Hartford, CT-06106 MedicalResearch.com: What are the main findings of the study? Answer:  We looked at brain response to a monetary incentive delay (MID) task in current and former cocaine users compared to healthy controls using functional MRI. The task measures aspects of sensitivity to rewards and punishments. Current cocaine users showed abnormal under-activation in reward circuitry compared to healthy controls. In some of those regions former cocaine users (who had an average of 4years of abstinence from cocaine) also showed abnormalities. These former users also showed over-activation in the ventral tegmental area of the midbrain, (an important region containing dopamine cell bodies) compared to both healthy controls and current cocaine users. Current and former cocaine users also scored higher on specific impulsivity measures, compared to healthy controls. (more…)

Nguyen Osteoporosis and Bone Biology Program Garvan Institute of Medical Research 384 Victoria Street, Darlinghurst NSW 2010 Australia MedicalResearch.com: What are the main findings of the study? Dr. Nguyen: We analyzed polymorphisms of the FTO (fat mass and obesity) gene in 934 elderly women of Caucasian background, and found that carriers of minor genotype (AA) of the SNP rs1121980 had a two-fold increase in the risk of hip fracture compared with carriers of major genotype (GG). Approximately 20% of women are carriers of the AA genotype. We estimate that about 17% of hip fracture cases could be attributed to the variation within the gene. (more…)

Dr. Hauck: We looked at data from the Infant Feeding Practices Study II, which followed mother from pregnancy through the first year of infant life. Mothers received several surveys that asked about infant feeding and bedsharing (sleeping with their infant in the same bed or other sleep surface). We found that mothers who bedshared for the longest time had the longest duration of breastfeeding compared with mothers who did not bedshare or bedshared for shorter times. Breastfeeding duration was also longer among mothers who were better educated, were white, had previously breastfed another child, had planned to breastfeed this baby, and had not returned to work in the first year after the baby was born.

Answer: Basically, two studies demonstrated that men’s tendency to engage in “off limits” sexual behaviors more than women is linked to sex differences in impulse, not control. In Study 1, we asked participants to reflect on previous times they succumbed to sexual temptations they felt were inappropriate some way. Based on their responses, we found that men both experienced stronger impulses and engaged in behavior based on these impulses more than women did. However, there was no reported difference in how much men and women exerted self-control. (more…)

MedicalResearch.com Interview with Selma Salihovic, Doctoral student Center for Developmental Research Örebro University MedicalResearch.com: What are the main findings of the study? Dr. Salihovic: Although previous research has examined the stability of psychopathic traits, our study offer a more nuanced perspective on development. Rather than asking whether psychopathic traits simply increase or decrease in adolescence, we asked about patterns of change for youths with different initial level of psychopathic traits. In this way, we could tease apart those youths with extreme levels from those with low and more transient levels, and follow their unique trajectories over four years. We could see that even among the youths with the highest levels there was a decreasing trend in two out of three core aspects of psychopathy. Although the degree of change was small, it was still a naturally occurring pattern for these youths, which raises the question whether an intervention designed to reduce these levels would have provided even a steeper decrease.
