MedicalResearch.com Interview with: Dr. Martha Iwamoto, MD, MPH Centers for Disease Control and Prevention, Atlanta, Georgia; MedicalResearch.com: What are the main findings of the study? Dr. Iwamoto: We have been successful in decreasing invasive MRSA infections among infants younger than 3 months, mostly due to declines in hospital –onset infections in NICUs. However, more needs to be done among pediatric patients older than 3 months, especially those in the community settings and without recent healthcare exposures. (more…)

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.

MedicalResearch.com Interview with: Dr Anoop Shah MBChB Cardiology Research fellow Centre of Cardiovascular sciences Chancellors Building University Of Edinburgh Little France Edinburgh MedicalResearch.com: What are the main findings of the study? Answer: Many studies have shown the effect of air pollution on cardiac mortality and myocardial infarction. Less studies have shown a similar effect on patients with heart failure. We therefore systemically reviewed and pooled data across 12 countries involving over 4 million patients with heart failure. We showed that air pollution has a close temporal association with either being hospitalized or dying from heart failure. Most of the effects of air pollution on patients with heart failure were acute. Most of the data that we analyzed came from developed countries across Europe and the USA. There was a  significant paucity of data from rapidly urbanizing nations such as India and China. (more…)

Argonde van Harten From the Alzheimer Center School for Mental Health and Neurosciences, Maastricht University Medical Center, Maastricht, the Netherlands.MedicalResearch.com Interview Invitation Argonde van Harten From the Alzheimer Center School for Mental Health and Neurosciences, Maastricht University Medical Center, Maastricht, the Netherlands. MedicalResearch.com: What are the main findings of the study? Answer: We found cerebrospinal fluid biomarker evidence of preclinical Alzheimer's disease (AD) predicted cognitive decline in patients with subjective complaints. These patients have cognitive complaints, but are cognitively normal at baseline. Preclinical AD predicted decline in memory performance, executive functions and global cognition over time. Most patients, however, had no evidence of preclinical AD and their cogntive functions generally remained stable over two years. Their memory performance improved. (more…)

Dr. Chris Bullen MBChB MPH PhD FAFPM FNZCPHM Director School of Population Health, The University of Auckland Private Bag 92019 Auckland 1142, New Zealand Co-Director of the NZ Tobacco Control Research Turanga: A national programme of research to inform rapid smoking prevalence reduction. Web: http://www.turanga.org.nz/ MedicalResearch.com: What are the main findings of the study? Dr. Bullen:
  • E-cigarettes, with or without nicotine, were modestly effective at helping smokers to quit, with similar levels of abstinence as with nicotine patches, and few adverse events.
  • ?At 6 months, verified abstinence was 7·3% with nicotine e-cigarettes, 5·8% with patches, and 4·1% with placebo e-cigarettes. However, there was insufficient statistical power to conclude superiority of nicotine e-cigarettes to patches or to placebo e-cigarettes.
  • No significant differences in rates of adverse events occurrence were found between the groups.
  • E-cigarettes, like the vapes found at MagicVaporizers, were very popular throughout the trial, with almost 90% of users stating they would recommend them to a friend trying to quit smoking.

Prof. Yarnold: A 3-week schedule of curative post-operative radiotherapy for women with breast cancer involving 15 treatments (fractions) delivered Monday to Friday each week, is at least as safe and effective as historical schedules given over 5 or 6 weeks. In fact the 3-week schedule is gentler on the healthy tissues than earlier standard regimens. (more…)

Prof Sally K Tracy DMid Midwifery and Women's Health Research Unit University of Sydney, Royal Hospital for Women Randwick, NSW, AustraliaMedicalResearch.com Interview with: Prof Sally K Tracy DMid Midwifery and Women's Health Research Unit University of Sydney, Royal Hospital for Women Randwick, NSW, Australia MedicalResearch.com: What are the main findings of the study? Prof. Tracy: We recruited 1748 pregnant women, of all risk types, from two tertiary teaching hospitals in different states in Australia and allocated them to receive either caseload midwifery care (871) or standard maternity care (877). The study found more women in caseload midwifery experienced an unassisted vaginal birth without pharmacological analgesia, and fewer women experienced an elective caesarean. While the trial findings did not show a statistically significant difference in the rate of caesarean sections between either group, the overall rate fell by more than 20 percent from pre-trial levels. Newborn infants in both groups achieved similar physical assessment scores (Apgar scores). A slightly lower number of pre-term births and neonatal intensive care admissions among the midwifery caseload group was not statistically significant. Important secondary findings of the study include:
  • 30 percent more spontaneous onset of labour
  • less induction of labour
  • less severe blood loss, and
  • stronger likelihood of breastfeeding at discharge from hospital.
These small differences accounted for an overall difference of AU$566.74 less with caseload midwifery than with standard care. Caseload midwifery appeared to alter some of the pathways that recurrently contribute to increased obstetric intervention.  Having this level of continuity of care works on the assumption that women will labour more effectively, need to stay in hospital less time and feel a stronger sense of satisfaction and personal control if they have the opportunity to get to know their midwife at the beginning of pregnancy.

MedicalResearch.com Interview with: Mohamad Fakih, MD, MPH Medical Director, Infection Prevention and Control St John Hospital and Medical Center MedicalResearch.com: What are the main findings of the study? Dr. Fakih: Urinary catheters are commonly used in the hospital.  Although they help in the management of the sickest patients, they also present a risk for infection and other harms to the patient. The Centers for Medicaid and Medicare Services (CMS) have made catheter associated urinary tract infections (CAUTI) publicly reportable, and no longer reimburse hospitals for these infections if they occur in hospital setting. The definition of CAUTI is based on the surveillance definition of the National Healthcare Safety Network (NHSN) by the Centers for Disease Control and Prevention (CDC). We looked at clinician practice, including the Infectious Diseases specialist’s impression and compared them to the NHSN definition. We found a significant difference between what clinicians think is a urinary catheter infection and give antibiotics for it compared to the NHSN definition. The NHSN definition predicted clinical infection by the Infectious Diseases specialist in only about a third of the cases. We also found that Infectious Disease specialists considered patients to have true CAUTI in only half of what clinicians treated as CAUTI. (more…)

MedicalResearch.com Interview with: Tasnime Akbaraly  PhD Institut National de la Santé et de la Recherche Médicale Montpellier, France MedicalResearch.com: What are the main findings of the study? Dr. Akbaraly: The aim of this study was to examine the association between chronic inflammation and a range of aging phenotypes, assessed approximately 10 years later in a large British population of men and women  -The Whitehall II Study-. As inflammation characterises a wide range of pathological processes, we considered several aging phenotypes, including cardiovascular disease (fatal and non-fatal), non-cardiovascular mortality and successful aging which encompasses optimal functioning across different physical, mental, and cognitive domains We found that chronic inflammation characterized by high levels of interleukin-6 (>2 pg/mL) twice over the 5-year exposure period nearly halved the odds of successful aging after 10–years of follow-up compared to maintaining low levels of interleukin-6 (<1pg/mL twice over the exposure period). Chronic inflammation was also associated with increased odds of future cardiovascular disease and non-cardiovascular mortality in a dose-response fashion. These associations were found to be independent of socio-economic factors, health behaviours (smoking, physical activity), and conditions such as obesity as well as the use of anti-inflammatory drugs and acute inflammation.

Dr. Ma: Regardless of race/ethnicity, diabetes increases the risk of mortality the same compared to non-diabetes among different race/ethnicity. However, since there are higher prevalence of  diabetes in Black and Hispanic, death rate due to diabetes is much higher in Black and Hispanic, this is because the diabetes prevalence rates are much higher in these population. Therefore, diabetes prevention is key to reduce diabetes related mortality disparities among racial/ethnic groups. (more…)

MedicalResearch.com Interview with: Matthew S. Pantell, MD, MS Department of Pediatrics University of California, San Francisco MedicalResearch.com: What are the main findings of the study? Dr. Pantell: First of all, our study confirms the strong association between social isolation and mortality in a nationally representative sample from the US. Furthermore, it shows that, within the same national sample, social isolation is a similarly strong predictor of mortality as compared to smoking, obesity, high blood pressure, and high cholesterol. Examining individual components of social isolation, our study shows that, among both women and men, not living with a partner and not participating in religious activities frequently are strong individual predictors of mortality. Finally, our work shows that infrequent social contact is associated with mortality among women, and not participating in social clubs/organizations is associated with mortality among men. (more…)

MedicalResearch.com Interview with: Ronald J. Iannotti, PhD Prevention Research Branch, Eunice Kennedy Shriver National Institute of Child Health and Human Development, Bethesda, Maryland Trends in Physical Activity, Sedentary Behavior, Diet, and BMI Among US Adolescents, 2001–2009 MedicalResearch.com: What are the main findings of the study? Dr. Iannotti: Although average BMI percentile increased from 2001 to 2005 it did not increase from 2005 to 2009. This is consistent with some recent studies that suggest the increase in overweight and obesity may be leveling off. We suggest that we may be 'bending the curve'. During the same period, physical activity and consumption of fruits and vegetables increased while television watching and consumption of sweets and sweetened beverages decreased. We cannot say whether television watching was replaced with more time spent on computers but we did not find an increase in computer use from 2005 to 2009. (more…)

Shoshana M. Rosenberg, ScD, MPH Researcher, Susan F. Smith Center for Women's Cancers Dana-Farber Cancer InstituteMedicalResearch.com Interview with: Shoshana M. Rosenberg, ScD, MPH Researcher, Susan F. Smith Center for Women's Cancers Dana-Farber Cancer Institute   MedicalResearch.com: What are the main findings of the study? Answer: Rates of contralateral prophylactic mastectomy (CPM) have been increasing among all breast cancer patients, however this trend has been most pronounced among the youngest women with breast cancer. Because of this trend, we sought to better understand why the youngest women - those diagnosed at age 40 or younger - were deciding to have this surgery. Many women not considered "high-risk", e.g., those without a cancer pre-disposing mutation, cited a desire to prevent the breast cancer from spreading as well as a desire to improve survival as reasons for undergoing the procedure, indicating they overestimate the benefit of having this surgery, as CPM does not affect these outcomes. While CPM does reduce the risk of developing breast cancer in the unaffected breast, in women who are not considered "high-risk", this risk is relatively low, however many women overestimated this risk as well.
