Medidr_jennifer_robinsoncalResearch.com Interview with: Jennifer G. Robinson, MD, MPH Professor ,Departments of Epidemiology & Medicine Director, Prevention Intervention Center Department of Epidemiology College of Public Health University of Iowa Iowa City, IA 52242-2007 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. (more…)

MedicalResearch Interview with: Monique Francois Teaching Fellow & Research Assistant at the University of Otago School of Physical Education, Sport and Exercise Sciences University of Otago Dunedin, New Zealand MedicalResearch: What are the main findings of the study? Answer: We found that small 'snacks' of interval exercise before the three main meals lowered postprandial blood glucose and contributed to a lower blood glucose across the day. Whereas 30 minutes of continuous moderate exercise before dinner did not lower postprandial blood glucose nor mean glucose levels the exercise day or the following day, compared to exercise snacking. Six one minute intervals as walking or a combination of walking and resistance 3x per day (before the three main meals) improved glycaemic control in individuals with insulin resistance. (more…)

MedicalResearch Interview with: Dr. Yan Qu Qingdao Municipal hospital Fruits and Vegetables Consumption and Risk of Stroke A Meta-Analysis of Prospective Cohort Studies MedicalResearch: What are the main findings of the study? Reply: First, both fruits and vegetables were found inversely associated with risk of stroke, and the relationships might be linear. Second, the inverse association of fruits and vegetables consumption with risk of stroke is consistent across subgroup analysis by outcome (stroke incidence and stroke mortality), location where the study was conducted (USA, Europe and Asia), sex (male and female), and stroke subtypes (ischemic and hemorrhagic). Third, citrus fruits, leafy vegetables and apples/pears were found inversely associated with risk of stroke. Fourth, very similar results were found in the subgroup analysis by status [yes: 0.78 (0.71-0.86) or no: 0.79 (0.74-0.85)] of adjusting for 6 or more of the 7 covariates (smoking, alcohol, blood pressure/hypertension, serum cholesterol, physical activity, body mass index, ≥3 dietary variables). These findings generally indicated that the association of fruits and vegetables consumption with the reduced risk of stroke may not be the result of confounding by the known factors. (more…)

prof_jayashri_kulharniMedicalResearch.com Interview with: Professor Jayashri Kulkarni MBBS, MPM, FRANZCP, PhD Monash University 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. (more…)

Aaron L. Leppin, MD Knowledge and Evaluation Research Unit Mayo Clinic, Rochester, MinnesotaMedicalResearch.com Interview with: Aaron L. Leppin, MD Knowledge and Evaluation Research Unit 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. (more…)

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. (more…)

Dr Alexandra Pitman MBBS MRC Psych MRC Clinical Research Fellow, UCL Division of Psychiatry, UCL (University College LondonMedicalResearch.com interview with: Dr Alexandra Pitman MBBS MRC Psych MRC Clinical Research Fellow, UCL Division of Psychiatry, UCL (University College London 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.

Author Interviews, Brigham & Women's - Harvard, Calcium, Heart Disease / 13.05.2014

Dr. Julie Paik, MD MPH Instructor, Harvard Medical School Brigham and Women's Massachusetts GeneralMedicalResearch.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.

MedicalResearch Interview with: Alicia J. Kowaltowski, MD, PhD Professor of Biochemistry Departamento de Bioquímica, IQ, Universidade de São Paulo São Paulo, SP, Brazil MedicalResearch: What are the main findings of the study? Dr. Kowaltowski: Intermittent fasting (24 hour cycles of all-you-can-eat followed by 24 fasting) is often used as a way to control excessive weight gain in laboratory animals, despite the fact that these animals overeat on the days they get food, and end up ingesting total quantities of food very similar to animals that eat every day. We show here that although lower weight gain occurs with intermittent fasting and there are some health benefits in adopting this diet, there are also some undesirable consequences. One such consequence is that this diet changes the control of hunger in the hypothalamus within the brain, making the rats hungry all the time, even when they are eating. (more…)

Vaughn, PhD Postdoctoral Trainee Department of Epidemiology Gillings School of Global Public Health University of North Carolina at Chapel Hill 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. (more…)

MedicalResearch Interview with: Dr. David Cook MD Professor in the Department of Anesthesiology Division of Cardiovascular Anesthesiology Center for the Science of Health Care Delivery Mayo Clinic College of Medicine Rochester, Minnesota. MedicalResearch: What are the main findings of the study? Dr. Cook: The main finding of the study was that segmentation of a population of surgical patients into groups of higher and lower complexity allowed us to apply a standardized practice, focused factory model to surgical care delivery. A standardized care model improved care process measures such as time on mechanical ventilation or duration of a bladder catheter indwelling. The model reduced resource utilization, decreasing patient time in all care environments (operating room, ICU and on ?the floor?). The care model improved outcomes at 30 days and reduced the costs overall and in every care environment. In addition to the absolute improvements in quality and in cost, the standardized care model reduced variation in all measured variables. That reduction in variation may be even more important than the improved outcomes or reduced costs because we now know it is possible to make the health care experience predictable for these patients. That predictability is critically important to patients and providers, but it also has implications for health care metrics and payment models. (more…)

MedicalResearch.com Interview with: Tara Dutta M.D. Vascular Neurology Fellow University of Maryland Medical Center MedicalResearch: What are the main findings of the study? Dr. Dutta: We analyzed data from the Stroke Prevention in Young Adults Study in order to evaluate for an association between self-reported marijuana use and ischemic stroke.   1,101 cases and 1,154 age, gender, and race-matched controls, aged 15-49 years old, were recruited from the greater Baltimore-Washington area between 1992 and 2008. Interviews were conducted to assess for various potential stroke risk factors, including illicit drug, alcohol, and tobacco use. Individuals reporting use of vasoactive illicit drugs, including cocaine and amphetamines, were excluded, yielding 751 cases and 813 controls. Logistic regression analysis was used to determine the association between marijuana use and ischemic stroke, adjusting for age, gender, race, current tobacco use, current alcohol use, hypertension, and diabetes. We did not find a positive association between marijuana use and ischemic stroke risk in our population of young-onset stroke patients compared to matched controls, even after controlling for current tobacco and alcohol use, hypertension, and diabetes.   A statistically significant inverse relationship was observed between remote use (defined as any use over one year ago) and stroke risk (adjusted OR 0.77, CI 0.61-0.98, p = 0.03). We also looked to see whether recent use (in the past 30 days), and particularly recent heavy use, was associated with ischemic stroke risk as has been suggested in the medical literature. Though our data did not show this association, the number of patients reporting recent use in our study was very small­­­­­­­. (more…)

Dr. Younossi: We conducted the analysis of the patient reported outcomes (PROs) data that were systematically collected during clinical trials of sofosbuvir-containing regimens. The highlights of our findings are as follows:
  1. Patients with Hepatitis C (HCV)  have a significant impairment of their health related quality of life including those related to activity and fatigue. Their work productivity is also impaired.
  2. Cirrhosis can add additional negative impact on some of these patient reported outcomes.
  3. During treatment, patients with cirrhosis who were treated with an interferon-free sofosbuvir and ribavirin containing regimen did experience mild decline in their patient related outcome scores. However, this decline was similar for HCV patients with or without cirrhosis.
  4. On the other hand, patients with cirrhosis who were treated with an interferon-containing regimen showed a significant decline in their patient reported outcomes scores compared to those with Hepatitis C and without cirrhosis.
  5. Nevertheless, at the end of week 12 follow up, there was no longer a significant deficit in PROs noted regardless of the treatment arm for patients with cirrhosis.
  6. Furthermore, for the patients (HCV and cirrhosis) who achieved a sustained virologic response at 12 weeks, there were significant improvements (compared to baseline) in some PRO scores.
  7. During treatment, changes in patient reported outcomes scores were similar between cirrhotics and non-cirrhotics for both treatment regimens (all p>0.05).

Dr. Ahuja: Severe mental illness is more common among college students than it was a decade ago, and the number of college students presenting for psychiatric care both on and off campus has dramatically increased. The rates of cannabis use have also been increasing among college students in the United States since the mid-1990s. The concomitant use of cannabis and other substances among general samples in psychiatric treatment has been linked to poorer clinical outcomes including increased hospitalizations, increased symptomatology, poorer treatment adherence, higher treatment resistance. However, before doing this study, there was no research that examined the effect of cannabis and other substance use disorders on the scholastic and general functioning of college students in psychiatric care.

Mireille Serlie, MD PhD Academic Medical Center University of Amsterdam Department of Endocrinology and Metabolism Amsterdam, The NetherlandsMedicalResearch.com Interview with: Mireille Serlie, MD PhD Academic Medical Center University of Amsterdam Department of Endocrinology and Metabolism Amsterdam, The Netherlands 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. (more…)

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. (more…)

San Francisco Departamento de Urología, Facultad de Medicina, Pontificia Universidad Católica de Chile, Santiago, Chile MedicalResearch: What are the main findings of the study? Answer: Increasingly, men with low-risk prostate cancer are undergoing a close monitoring regimen called active surveillance, instead of moving forward immediately with treatment. However it is still unclear which men will develop evidence for worsening or more aggressive disease during active surveillance. In this study of 154 men with Gleason 6 prostate cancer followed for 38 months, we found that low levels of free testosterone were significantly associated with increased risk of developing more aggressive disease. We found no significant association with total testosterone concentrations, although there was a general trend towards increased risk with lower levels. (more…)

Sommers, MD, PhD Assistant Professor of Health Policy & Economics Harvard School of Public Health / Brigham & Women's Hospital Boston, MA 02115   MedicalResearch.com: What are the main findings of the study? Dr. Sommers: We find that over the first four years since Massachusetts' 2006 comprehensive health reform law, all-cause mortality in the state fell by 2.9%, compared to a similar population of adults living in counties outside Massachusetts that did not expand insurance during this period.  We also found that the law reduced the number of adults in Massachusetts without insurance, reduced cost-related barriers to care, increased use of outpatient visits, and led to improvement in self-reported health.  Overall, we estimate that the health reform law prevented over 320 deaths per year in the state - or one life saved per 830 adults gaining health insurance.  Mortality rates declined primarily due to fewer deaths from causes amenable to health care, such as cancer, infections, and heart disease.  We also found that the health benefits were largest for people living in poor counties in the state, areas with higher percentage of uninsured adults before the law was passed, and for minorities.
