MedicalResearch: What are the main findings of the study?
Dr. Mani: Our group has identified a gene that when mutated it causes a form of truncal (central) obesity that is associated with a cluster of coronary artery disease risk factors, including high blood pressure, insulin resistance and possibly elevated blood lipids. These associated risk factors are collectively known as the metabolic syndrome, which may lead to development of diseases such as diabetes and coronary artery disease, both of which were very prevalent in the populations we studied. All identified mutations by our group have been so far gain of function mutations, which means they increased the activity of the gene in pathways related to adipogenesis and gluconeogenesis.

MedicalResearch: What are the main findings of the study?
Dr. Bellgowan: These results demonstrate 14% and 24% smaller hippocampal volumes in collegiate football players with and without a history of concussion relative to education-, sex- and age-matched controls participants. Further, the number of years of tackle football experience was correlated with smaller hippocampi and slower baseline reaction times. The hippocampus plays a key role in memory and emotional regulation. Volumetrics of other medial temporal lobe structures (I.e. The amygdala) did NOT show differences among groups suggesting that this effect is localized to the hippocampus.

MedicalResearch: What are the main findings of the study?
Dr. Robinson: The PCSK9 antibody, evolocumab, reduced LDL (or bad) cholesterol by about 65-70% regardless of the dose or type of statin used. This is a greater percentage reduction than ezetimibe, another drug used to lower LDL cholesterol in statin-treated patients, which lowered LDL cholesterol 15-20%. Side effects of evolocumab were similar to those for ezetimibe or placebo.

MedicalResearch.com: What are the main findings of the study?
Professor Kulkarni: Persistent schizophrenia is difficult and unfortunately common, despite advances over the past years in antipsychotic drug development. New treatment approaches are urgently needed. Also, a specific focus for women with schizophrenia is still somewhat lacking and there is a need to consider the special issues facing women with schizophrenia.
Over many years, we have been conducting clinical trials to develop the role of adjunctive estradiol use to treat symptoms of schizophrenia. This study is the largest clinical trial in the world of this type and we found that in an 8 week, three arm, double blind, placebo-controlled, adjunctive trial of transdermal estradiol (200mcg v 100mcg v placebo) in 183 women with schizophrenia, that the women who received either 200mcg or 100mcg transdermal estradiol made a better recovery. The women who received 200mcg transdermal estradiol made a slightly better recovery than women receiving 100mcg transdermal estradiol. Both estradiol groups were significantly better than the group who received adjunctive transdermal placebo.

MedicalResearch.com Interview with:
Aaron L. Leppin, MD

Mayo Clinic, Rochester, Minnesota
MedicalResearch.com: What are the main findings of the study?
Dr. Leppin: We conducted a systematic review and meta-analysis of randomized trials assessing the effectiveness of hospital discharge interventions on reducing 30-day readmission rates. We identified 47 trials, 42 of which contributed to the primary meta-analysis.
Overall, the interventions that have been tested to reduce early hospital readmissions reduce them by about 20%.
The ones that are most effective, though, reduce them by almost 40% and use a consistent but complex approach. These interventions make a robust effort to fully understand the patient’s post-discharge context, often by visiting the patient’s home. They focus on identifying all the things the patient needs to do to be well—whether that’s organizing medications, getting a ride to the clinic, or paying the electric bill—and they determine whether the patient has the necessary resources and capacity to pull it all off. When limitations are found, these interventions have a strategy in place to support the patient through the post-discharge period.

MedicalResearch: What are the main findings of the study?
Dr. Redelmeier: We identified every woman in Ontario, Canada, who gave birth to a newborn baby between 2006 and 2011 and then evaluated each driver for the months before, during, and after pregnancy. This amounted to about half a million women who accounted for almost 8000 serious crashes that sent the driver to hospital. We found that the second trimester of pregnancy led to a 42% increase in the risk of a serious motor vehicle crash. The increased risk included diverse populations, distinct obstetrical cases, different crash characteristics. The risk equated to about twice the population norm but was still below male drivers at this age.

MedicalResearch: What are the main findings of the study?
Answer: We conducted a systematic review of all published research comparing the experience of suicide bereavement with bereavement due to other causes, in which we considered the evidence from 57 studies evaluating the effect of bereavement on death, mental health, and social functioning of family members, friends, and other close contacts of the deceased. These studies showed that parents and children bereaved by suicide were at higher risk of mental health problems after the loss than parents and children bereaved by other causes, and that spouses and mothers bereaved by suicide were at higher risk of suicide than spouses and mothers bereaved by other causes. We also found some evidence that people from a range of kinship groups bereaved by suicide report more rejection and shame than people bereaved by other violent deaths, and that feeling stigmatised by the death is commonly experienced after any violent bereavement. It seemed that people bereaved by violent deaths, for example due to accidental death, homicide, drug-related death, motor vehicle crash, undetermined death or suicide, shared a sense of feeling blamed for the death or tainted by their association with the deceased.
MedicalResearch.com Interview with:
Dr. Julie Paik, MD MPH MSc
Instructor, Harvard Medical School
Brigham and Women's Hospital
MedicalResearch: What are the main findings of the study?
Dr. Paik: Many women in the United States take calcium supplements. One study found that over 60% of women aged 60 and over in the United States were taking calcium supplements. However, the medical community is still not certain of the effects of calcium supplements in women, particularly on cardiovascular disease risk. For this reason, we studied 74,245 women participating in the Nurses' Health Study over a 24-year follow-up period for their risk of developing cardiovascular disease (heart disease or stroke). We found that there was no increased risk of heart disease or stroke among women taking calcium supplements during the 24-year follow-up period. Our paper has several distinct strengths compared to prior studies including the large sample size, long follow-up period, cases of cardiovascular disease that were confirmed by medical record review, detailed and repeated assessment of calcium supplement use, and detailed information about other risk factors for cardiovascular disease.

Dr. Wang: The results of this study demonstrate that differences in prevalence of reported food allergies exist in elementary schools representing diverse socioeconomic and racial/ethnic characteristic. In this study, we conducted a survey at 4 elementary schools in New York City, 2 private schools that had a predominantly White student body with over 80% of families having paid a full tuition of over $35,000 per year and 2 public charter schools that had a primarily Black and Hispanic student body where over 90% of students qualified for free or reduced price school lunch. The results show a high rate of reported food allergy, with rates significantly higher in the private school population as compared to the public charter school population.

Kwang-il Kim, MD, PhD
Associate Professor, Department of Internal Medicine,
Seoul National University College of Medicine,
Seoul National University Bundang Hospital,
Seoul, Republic of Korea
MedicalResearch: What are the main findings of the study?
Answer: There are few tools of preoperative risk stratification for the older adults. We found that not only disease itself but also frailty can lead to post-operative complication and mortality. So we made a scoring model to predict post-operative mortality and morbidity based on comprehensive geriatric assessment and it worked exactly.
MedicalResearch: Were any of the findings unexpected?
Answer: Under our predictive model, there was inflection point of mortality slope at point 5. Post-operative mortality of someone who scores 4~5 is below 10%, but it of other who scores 6~7 is about 30%. It was unexpected drastic change, so we think that there is physiologic threshold point.
MedicalResearch: What should clinicians and patients take away from your report?
Answer: Because the elderly are different from adults, clinicians have to focus on functional capacity, co-morbidity, and frailty for their older surgical patients. Make operative decision base on comprehensive geriatric assessment or our scoring model. If you depend on your own feeling, some older patients will suffer from post-operative complication and someone will forfeit his chance of surgery.

MedicalResearch: What are the main findings of the study?
Dr. Vaughn: Outdoor workers are at high-risk for tick-borne diseases. Adherence to recommended tick-bite prevention methods is poor. While permethrin treatment of clothing is highly protective against many arthropod vectors, the need for frequent reapplication lessens adherence. A double-blind randomized intervention was conducted to determine the effectiveness of long-lasting permethrin-impregnated uniforms for tick bite prevention among outdoor workers from North Carolina. Treatment group uniforms were factory-impregnated with long-lasting permethrin by Insect Shield, while control group uniforms received sham treatment. Participants completed weekly tick bite logs during two tick seasons. 130 participants reported 1,045 work-related tick bites over 5,251 person-weeks of follow-up. The effectiveness of long-lasting permethrin impregnated uniforms for prevention of work-related tick bites was 82% (p<0.001) for the first year and 34% (p=0.38) for the second year. These results indicate that long-lasting permethrin impregnated uniforms are highly effective for at least one year against tick bites among North Carolina outdoor workers.

MedicalResearch What are the main findings of the study?
Dr. Serlie: We studied the effects of hypercaloric high sugar or high fat/high sugar drinks consumed with the 3 main meals (representing an increase in meal size) or in between the 3 main meals (representing an increase in meal frequency or snacking). All subjects gained a similar amount of body weight but only the ones that snacked showed an increase in liver and abdominal fat. This suggests that besides caloric content and diet composition, eating pattern independently contributes to liver and abdominal fat accumulation. We also observed a trend for a decrease in hepatic insulin sensitivity in the high fat/high sugar frequency group only.
MedicalResearch.com Interview with:
Luisa Soares-Miranda, PhD
Research Center in Physical Activity, Health and Leisure

Rua Dr. Plácido Costa,
Porto PORTUGAL
MedicalResearch: What are the main findings of the study?
Dr. Soares-Miranda: Modest physical activity, such as the distance and pace of walking, is important for the heart’s electrical well being of older adults. In our study, older adults that increased their walking pace or distance had a better heart rate variability when compared with those that decreased their walking pace or distance. Our results suggest not only that regular physical activity later in life is beneficial, but also that certain beneficial changes that occur may be reduced when physical activity is reduced. This supports the need to maintain modest physical activity throughout the aging process. Even small increases can lead to a better health, while reducing physical activity has the opposite effect. So, any physical activity is better than none, and more is better.
