Author Interviews, Blood Pressure - Hypertension, JAMA / 19.06.2014

Carlos J. Rodriguez, MD, MPH Department of Medicine and Public Health Sciences, Wake Forest University School of Medicine, Winston-Salem, North CarolinaMedicalResearch.com Interview with Carlos J. Rodriguez, MD, MPH Department of Medicine and Public Health Sciences, Wake Forest University School of Medicine, Winston-Salem, North Carolina MedicalResearch: What are the main findings of the study? Dr. Rodriguez: As a clinician there is a notion suggesting that lower blood pressure is better but our current research to date is controversial and not conclusive. We wanted to study a large group of people with hypertension and see whether over 20 years of follow up, if a lower systolic blood pressure would be associated with lower cardiovascular events (heart attack, stroke, heart failure, angina). We hypothesized that there would be a linear association between blood pressure and events, that lower blood pressure would be associated with lower events and that as the blood pressure went up there would be more events. We found this was not the case but that hypertensives with a blood pressure between 120-138mmhg have the greatest benefit and those with a blood pressure less than 120mmhg did not have additional benefit.

Monika Waszczuk 1+3 PhD Student MRC SGDP Research Centre Institute of Psychiatry, King's College London DeCrespigny Park London UKMedicalResearch.com Interview with: Monika Waszczuk 1+3 PhD Student MRC SGDP Research Centre Institute of Psychiatry, King's College London DeCrespigny Park London UK MedicalResearch: What are the main findings of the study? Answer: Little is known about the genetic influences on the relationship between depression and anxiety disorders across development. We used two population-based prospective longitudinal twin and sibling studies to investigate phenotypic associations between the symptoms of these disorders, and tested genetic structures underlying these symptoms across three developmental stages: childhood, adolescence and early adulthood. We found that depression and anxiety disorder symptoms are largely distinct in childhood and are influenced by largely independent genetic factors. Depression and anxiety symptoms become more associated and shared most of their genetic etiology from adolescence. An overarching internalizing genetic factor influencing depression and all anxiety subscales emerged in early adulthood. These results provide preliminary evidence for different phenotypic and genetic structures of internalizing disorder symptoms in childhood, adolescence and young adulthood, with depression and anxiety becoming more associated from adolescence.

Author Interviews, Hospital Readmissions, JAMA / 17.06.2014

Greg D. Sacks, MD, MPH Department of Surgery, David Geffen School of Medicine at UCLA MedicalResearch.com Interview with: Greg D. Sacks, MD, MPH Department of Surgery, David Geffen School of Medicine at UCLA MedicalResearch: What are the main findings of this study? Dr. Sacks: This study evaluated the all-cause readmissions measure developed by the Centers for Medicare and Medicaid Services to penalize hospitals for unplanned readmissions. By evaluating readmissions of surgical patients at a single academic medical center, we found that the readmissions measure was able to identify only a third of the planned readmissions and mislabeled the remaining two thirds of planned readmissions as unplanned. This discrepancy was a result of the measure’s reliance on administrative claims data, which disagreed in 31% of cases with clinical data abstracted from the patient’s chart. Also, almost a third (27%) of the readmissions in this study were for reasons unrelated to the original hospitalization. (more…)

Dr.  Kendzerska: Based on a large sample of more than 8,500 participants with suspected sleep apnea, our study shows that among people with obstructive sleep apnea (OSA), and controlling for risk factors for diabetes development, initial OSA severity predicted risk for incident diabetes. Measures of the physiologic consequences of OSA (e.g., low level of oxygen, sleep deprivation) were also risk factors for diabetes in this population. (more…)

Roumie, MD MPH Associate Professor Internal Medicine and Pediatrics Institute for Medicine and Public Health Vanderbilt University Staff Physician VA Tennessee Valley Healthcare System Nashville TN 37212 MedicalResearch: What are the main findings of the study? Dr. Roumie: This retrospective cohort study compared time to acute myocardial infarction (AMI), stroke, or death among Veterans with diabetes that were initially treated with metformin, and subsequently added either insulin or sulfonylurea. Among 178,341 Veterans on metformin monotherapy, 2,948 and 39,990 added insulin or sulfonylurea, respectively. Patients were about 60 years old, about 35% had history of heart disease or stroke, had been on metformin for an average of 14 months and their hemoglobin A1c was 8.1% at the time of addition of the second medication. Compared to those who added a sulfonylurea, those who added insulin to metformin had a 30% higher risk of the combined outcome of heart attack, stroke, and all-cause mortality. Although new heart attacks and strokes occurred at similar rates in both groups, mortality was higher in patients who added insulin. (more…)

Lee, Pharm.D., Ph.D. Assistant Professor Department of Pharmacy Practice College of Pharmacy Oregon State University/Oregon Health and Science University Portland OR, 97239 MedicalResearch: What are the main findings of the study? Dr. Lee: We found that older men taking a statin were less physically active and had more sedentary behavior. They had about 37 minutes of less moderate exercise per week. For comparison, the American heart Association recommends about 40 minutes of moderate activity 3-4 times per week. We also found that those that started using a statin during the study had the largest drop in physical activity. (more…)
Author Interviews, Depression, JAMA, Weight Research / 06.06.2014

MedicalResearch.com Interview with: Aurélie Lasserre ,MD Center for psychiatric epidemiology and psychopathology Department of Psychiatry Lausanne University Hospital (CHUV) Site de Cery, Switzerland MedicalResearch: What are the main findings of this study? Dr. Lasserre: Several recent studies have shown that Major Depressive Disorder with atypical features (defined as having a depressive episode where mood reactivity is maintained and two of the following features: increase in appetite, hypersomnia (oversleeping), leaden paralysis (heavy limbs) and increased sensitivity to rejection) was associated with obesity, but the temporal sequence was not known, i.e. it was not clear whether atypical depression predisposes to obesity or the converse. Our study revealed that Major Depressive Disorder with atypical features does lead to an increase in body-mass index, obesity, waist circumference and fat mass over a period of 5 years. This result was not explained by socio-demographic characteristics, alcohol or tobacco consumption, physical activity, co-existing mental disorders or medication. Interestingly, we also observed that the weight gain in subjects with atypical features was not a temporary phenomenon but it persisted after the remission of the depressive episode and was not attributable to new episodes.

Dr. Christopher Wildeman PhD Associate Professor of Sociology Faculty fellow at the Center for Research on Inequalities and the Life Course (CIQLE), and at the Institution for Social and Policy Studies (ISPS) at Yale University.MedicalResearch.com Interview with Dr. Christopher Wildeman PhD Associate Professor of Sociology Faculty fellow at the Center for Research on Inequalities and the Life Course (CIQLE), and at the Institution for Social and Policy Studies (ISPS) at Yale University. MedicalResearch.com: What are the main findings of the study? Dr. Wildeman: There are four key findings in the study. First, the cumulative risk of having a confirmed maltreatment report any time between birth and age 18 is much higher than most people would have thought. Fully 1 in 8 American children will experience this event at some point. Second, the risk of experiencing this event is highly unequally distributed, with Black and Hispanic experiencing it much more than Hispanic, White, and (especially) Asian children. Between 1 in 4 and 1 in 5 Black children will have a confirmed maltreatment report at any time in their childhood. For Native American, the risk is about 1 in 7. Third, the risk of maltreatment is quite similar for boys and girls. Finally, the highest risks of child maltreatment are in the first few years of life, suggesting that interventions aiming to diminish maltreatment should focus on parents with very young children.

Reed Jost, MS Retina Foundation of the Southwest 9600 N Central Expwy, Suite 200 Dallas, TX 75231MedicalResearch.com Interview with: Reed Jost, MS Retina Foundation of the Southwest 9600 N Central Expwy, Suite 200 Dallas, TX 75231   MedicalResearch: What are the main findings of the study? Answer: Commercially available automated screening devices assess refractive risk factors, not amblyopia or strabismus, resulting in under-referral of affected children and over-referral of healthy children to pediatric eye care professionals. The Pediatric Vision Scanner is a binocular retinal birefringence scanner that directly detects strabismus and amblyopia by analyzing binocular scans for the presence or absence of birefringence, which is characteristic of steady, bifoveal fixation. We found that the Pediatric Vision Scanner outperformed an automated, refractive error screener (SureSight Autorefractor) in a cohort of 300 patients (2-6 years) tested in a pediatric ophthalmology setting. Compared to the SureSight, the Pediatric Vision Scanner had significantly higher sensitivity and higher specificity in the detection of strabismus and amblyopia. (more…)

Dr. Wu: We performed a randomized trial at 2 urban free-standing children's hospitals, comparing inhaled 3% hypertonic saline to 0.9% normal saline in patients under 24 months with bronchiolitis. Patients with prematurity less than 34 weeks, cyanotic heart disease, chronic pulmonary disease, and previous episodes of wheezing or bronchodilator use were excluded. Patients were 4 mL of study medication nebulized up to 3 times in the emergency department; if admitted, patients continued to receive the assigned study medication three times a day until discharge. A total of 408 patients were analyzed. We found that 28.9% of patients treated with hypertonic saline required hospital admission, compared with 42.6% of patients in the normal saline group. (more…)

MedicalResearch.com Interview with Dr. Edythe D.London PhD Professor, Departments of Psychiatry and Biobehavioral Sciences, and Molecular and Medical Pharmacology David Geffen School of Medicine, UCLA Dr. Edythe  D.London PhD Professor, Departments of Psychiatry and Biobehavioral Sciences, and Molecular and Medical Pharmacology David Geffen School of Medicine, UCLA MedicalResearch: What are the main findings of the study? Dr. London: Brain function related to risky decision-making was different in stimulant users  (methamphetamine users) than in healthy control subjects. In healthy controls, activation in the prefrontal cortex (right dorsolateral prefrontal cortex) during risk-taking in the laboratory was sensitive to the level of risk. This sensitivity of cortical activation was weaker in stimulant users, who instead had a stronger sensitivity of striatum activation. The groups also differed in circuit-level activity (network activity) when they were not performing a task but were “at rest.”  Stimulant users showed greater connectivity within the mesocorticolimbic system, a target of abused drugs. This connectivity was negatively related to sensitivity in the prefrontal cortex to risk during risky decision-making. In healthy control subjects, connectivity between the right dorsolateral prefrontal cortex and striatum was positively related to sensitivity of prefrontal cortical activation to risk during risky decision-making.

William Kronenberger, Ph.D., HSPP Professor and Director, Section of Psychology Acting Vice Chair of Administration Department of Psychiatry Indiana University School of Medicine Riley Child and Adolescent Psychiatry ClinicMedicalResearch.com Interview with: William Kronenberger, Ph.D., HSPP Professor and Director, Section of Psychology Acting Vice Chair of Administration Department of Psychiatry Indiana University School of Medicine Riley Child and Adolescent Psychiatry Clinic MedicalResearch: What are the main findings of the study? Dr. Kronenberger: The main findings of the study are that children with cochlear implants had two to five times the risk of delays in executive functioning compared to children with normal hearing.  Executive functioning is the ability to regulate and control thinking and behavior in order to focus and achieve goals; it is important for everything from learning to social skills.  The areas of executive functioning that were most affected in children with cochlear implants were working memory, controlled attention, planning, and concept formation.  Approximately one-third to one-half of the sample of children with cochlear implants had at least mild delays in these areas, compared to one-sixth or fewer of the normal-hearing sample.  We think that reduced hearing experience and language delays cause delays in executive functioning to occur at higher rates in children with cochlear implants.

Dingell VA Medical Center Associate Dean for Veterans Affairs & Professor of Surgery Wayne State University School of Medicine John D. Dingell VA Medical Center Chief of Staff Detroit, MI 48201 MedicalResearch: What are the main findings of the study? Dr. Gruber: We successfully addressed the problem of inadequate intracellular delivery of tumor- specific antigens (TSAs) to dendritic cells (DCs) by using synthetic cell-penetrating domains or peptides (CPPs) to create fusion tumor antigens (Ags) that readily penetrate through the plasma membrane. We demonstrated cloning and purification of the TSA melanoma-associated antigen 3 (MAGE-A3) in frame with CPP, producing enhanced cytosolic bioavailability in dendritic cells without altering cell functionality. Further, we showed that recombinant bacterial proteins can be easily engineered to purify large amounts of CPP-MAGE-A3. Use of full-length proteins circumvents the need to define HLA class I allele binding before vaccination and increases the number of epitopes recognized by CD8+ cytotoxic T lymphocytes (CTLs) when compared with peptide-pulsed dendritic cells. Finally, the use of proteins rather than plasmids or viral vectors for in vitro dendritic cell vaccine preparation avoids the practical and theoretical safety concerns regarding genomic modification.

Dr. Hawley: There are a couple of main findings.
  • First, we found that nearly 20% of women in our population based sample of breast cancer patients reported strongly considering having contralateral prophylactic mastectomy (CPM, which means they had their unaffected breast removed at the same time as the breast with cancer), and about 8% received it. Of those who did receive contralateral prophylactic mastectomy, most (about 70%) did not have a clinical indication for it, which included a positive genetic mutation of BRCA1 or BRCA2 or a strong family history of breast or ovarian cancer.
  • However, most women (90%) who received it reported having a strong amount of worry about the cancer coming back (also called worry about recurrence).
  • We also found that when women had an MRI as part of their diagnostic work-up for breast cancer, they more often received contralateral prophylactic mastectomy than when they did not have an MRI.

Dr. Stroup: We conducted a study sponsored by the National Institute of Mental Health that compared long-acting injectable antipsychotics for people with schizophrenia. Long-acting injectable antipsychotics, also known as depot antipsychotics, are used to promote treatment adherence.  We compared a newer injectable antipsychotic, paliperidone palmitate, to an older one, haloperidol decanoate.  We did not find an advantage for the newer drug in overall effectiveness.  The drugs performed very similarly, and were tolerated about the same.

Dr. Wei Bao: This study, to our knowledge, is the first attempt to examine the associations of physical activity and sedentary behaviors with risk of type 2 diabetes mellitus (T2DM) among women with a history of gestational diabetes mellitus (GDM), which is a high-risk population of T2DM. The main findings are: (1) Physical activity is inversely associated with risk of progression from GDM to T2DM. Each 5-metabolic equivalent hours per week increment of total physical activity, which is equivalent to 100 minutes per week of moderate-intensity physical activity or 50 minutes per week of vigorous physical activity, was related to a 9% lower risk of T2DM; this inverse association remained significant after additional adjustment for body mass index (BMI). (2) An increase in physical activity is associated with a lower risk of progression from gestational diabetes mellitus to T2DM. Compared with women who maintained their total physical activity levels, women who increased their total physical activity levels by 7.5 MET-h/wk or more (equivalent to 150 minutes per week of moderate-intensity physical activityor 75 minutes per week of vigorous physical activity) had a 47% lower risk of T2DM; the association remained significant after additional adjustment for BMI. (3) Prolonged time spent watching TV, as a common sedentary behavior, is associated with an increased risk of progression from gestational diabetes mellitus to T2DM. Compared with women who watched TV 0 to 5 hours per week, those watched TV 6 to 10, 11 to 20, and 20 or more hours per week had 28%, 41%, and 77%, respectively, higher risk of T2DM. The association was no longer significant after additional adjustment for BMI. (more…)

Professor Bennell: In 102 people with painful hip osteoarthritis, we compared a 'real' physical therapy program involving exercise, manual therapy techniques,education and provision of a cane if appropriate to a sham physical therapy treatment that was made to look as though it was real but instead involved turned off ultrasound and gentle application of a hand crème to the hip region. Participants in both groups went to see a physical therapist on 10 occasions over 12 weeks and performed home exercises if in the 'real' physical therapy group or lightly applied the cream at home if in the sham group. Participants were followed for 9 months in total. We found that while both groups showed improvements in pain and physical function, the improvements were similar between the two groups. That is, the real physical therapy program did not show greater benefits over a sham treatment.  (more…)

Scales, Jr MD MSHS Assistant Professor of Surgery Division of Urologic Surgery Duke University Medical Center   MedicalResearch: What are the main findings of the study? Dr. Scales: When it comes to treating kidney stones, less invasive is not always better. We used the best method short of a randomized trial to balance out patients in terms of factors that might influence the success of treatment.  In other words, we achieved a “statistical toss-up” for factors that could influence the outcome of the procedure. When we balanced out all of the factors that might influence the chance of a repeat procedure, we found that about 11% of patients treated with non-invasive SWL had a repeat procedure, as compared to <1% with minimally invasive URS.

Dr. Munoz: 1. Tdap vaccine was safe and well tolerated during pregnancy 2. Women who are pregnant have adequate responses to the Tdap vaccine, similar to those of women who are not pregnant. 3. Antibodies to pertussis are efficiently transferred to the fetus through the placenta so that babies of mothers who were vaccinated during pregnancy had significantly higher concentrations of antibody at birth and up to 2 months of age, when compared to infants of mothers who were vaccinated post-partum. 4. Higher antibody concentrations in the first two months of life are likely to provide protection against pertussis during this period of high vulnerability 5. Infants of mothers who were vaccinated during pregnancy had adequate responses to their routine pertussis vaccines at 2, 4, and 6 months of age, and had expected and adequate responses to their 4th dose of vaccine at 1 year of age. The absolute concentration of antibodies to some of the pertussis antigens might be modestly lower after the primary series of vaccines in some infants of mothers who were vaccinated during pregnancy, but this difference does not persist after the 4th dose.
