MedicalResearch.com Interview with: Arif Khan, MD Medical Director, Northwest Clinical Research Center Adjunct Professor of Psychiatry Duke University Medical Center and Christine Khan, Psychiatric Nurse 1951 – 152nd  Place NE Northwest Clinical Research Center Bellevue, WA 98007 MedicalResearch.com: What are the main findings of your study?
  1. The original idea set in early 20th century that psychiatric patients discharged from mental hospitals had a shortened life span or faced early death was supported by this analysis of psychiatric patients participating in research trials for new medications.  There was no increased risk of early death or shortened life span for participating in these research clinical trials. 
  2. Life span shortening or increased risk of early death is highest among patients with schizophrenia, followed by patients with major mood disorders such as Bipolar Mood Disorder and Major Depression. (more…)

Answer: We tested the hypothesis that late-onset Alzheimer disease (AD) might be in part explained by the homozygosity of unknown loci. In a genome-wide study of a Caribbean Hispanic population with noticeable inbreeding and high risk of AD we assessed the presence of long runs of homozygosity (ROHs) – regions where the alleles inherited from both parents are identical. Our results suggest the existence of recessive AD loci, since the mean length of the ROH per person was significantly longer in AD cases versus controls, and this association was stronger in familial AD.

Answer: We examined the link between sitting-time and physical activity with current and future depressive symptoms in 8,950 mid aged women, who participated in the Australian Longitudinal Study on Women’s Health. Both high sitting-time and low physical activity levels were associated with higher risk of current depressive symptoms, and in combination, the risk further increased. Compared with women sitting ≤4 hours/day and meeting the physical activity recommendations of at least 150 minutes of moderate intensity activity per week, women who sat >7 hrs/day and who did no physical activity were three times as likely to have depressive symptoms. However, only lack of physical activity was associated with increased risk of future depressive symptoms, irrespective of sitting-time. Women who did no physical activity were 26% more likely to have future depressive symptoms than women meeting physical activity recommendations. (more…)

Answer: The findings of our study were the following: (1) The low frequency component of systolic blood pressure variability (LFSBP;  a marker of sympathovagal tone) was a stronger predictor of depressive symptoms than conventional measures of cardiovascular functioning such as laboratory measurement of blood pressure and heart rate variability as well as home based ambulatory blood pressure monitoring (2) Depressive symptoms were associated with a blunted LFSBP response to sympathetic stimulation via cold pressor test; and (3) Participants with acute depression (a score of ≥16 using the CES-D scale) had higher LFSBP than those with normal depressive symptom scores.  These findings suggest that depressive symptoms evoke alterations in vascular sympathetic activity, and more importantly, this alteration is occurs early in the progression of the disease.  This is fascinating owing to the fact that we have documented a common pathway of disease between depression and cardiovascular diseases.

Answer: We found that collaborative care improves depression immediately after treatment compared to usual care, has effects that persist to 12 month follow-up and is preferred bypatients over usual care. This difference in effect equated to a standardized effect size of 0.26 (95% CI 0.07 to 0.46). More participants receiving collaborative care than those receiving usual care met criteria for recovery (odds ratio 1.67 (95% confidence interval 1.22 to 2.29); number needed to treat=8.4) and response (1.77 (1.22 to 2.58); 7.8 at 4 months. At 12 months follow up more participants in collaborative care than those in usual care met criteria for recovery (odds ratio 1.88 (95% confidence interval 1.28 to 2.75); number needed to treat=6.5) and response (1.73 (1.22 to 2.44); 7.3. Collaborative care is as effective in the UK healthcare system—an example of an integrated health system with a well developed primary care sector—as in the US. (more…)

MedicalResearch.com Interview with: Brian D. Glass Biological and Experimental Psychology, School of Biological and Chemical Sciences, Queen Mary, University of London, London, United Kingdom Bradley C. Love Department of Cognitive, Perceptual and Brain Sciences, University College London, London, United Kingdom MedicalResearch.com: What are the main findings of the study? Answer: We had 72 non-gaming participants play 40 hours of video games over 6 to 8 weeks. We tested them on psychological tests before and after. The participants either played The Sims (a life simulator game), or one of two versions of StarCraft (a real-time strategy game) -- one which had a higher level of complexity. We found that the StarCraft players (especially on the higher complexity version) performed better on specifically the psychological tasks which tested cognitive flexibility. Cognitive flexibility is the ability to adapt to a changing environment by keeping multiple things in mind and switch between tasks effectively. This sort of ability is considered a higher level psychological ability because it requires strategic thinking and creativity.

Answer: There are three important findings in our study. We estimated a population-based Autism Spectrum Disorder (ASD) sibling recurrence risk relative to the background population and found an almost seven-fold increase. While this indeed is an increased risk, it is also lower than what other recent studies have suggested. We also compared the relative recurrence risk for full and maternal/paternal half siblings and found a lower relative recurrence risk in half siblings than in full siblings, which supports the genetic pathway to ASD. The recurrence risk for maternal half siblings is still higher than for the background population suggesting that factors unique to the mother, such as the intrauterine environment and perinatal history, may contribute to ASD. Last, but not least, we estimated the time trends in the relative recurrence risk. While the ASD prevalence has been increasing for several years, we found no time trends in the relative recurrence risk, suggesting that the factors contributing to the risk for ASDs recurrence in siblings (perhaps a combination of genes and environment) have not changed over time.

MedicalResearch.com Interview with: Dr. Ramon Trullas Research Professor CSIC Institute of Biomedical Research of Barcelona MedicalResearch.com: What are the main findings of the study? Answer: The findings reported in this manuscript that we consider can be underscored are: 1) Asymptomatic subjects at risk of developing sporadic Alzheimer’s disease (AD), as well as symptomatic patients diagnosed with probable sporadic AD show a low concentration of circulating cell free mitochondrial DNA (mtDNA) in cerebrospinal fluid (CSF). 2) Pre-symptomatic subjects carrying pathogenic PSEN1 gene mutations which cause early onset familial AD, also exhibit low mtDNA content in CSF. 3) Reduced mtDNA content in CSF occurs in preclinical PSEN1 mutation carriers at least one decade before patients are expected to manifest clinical signs of dementia and well before any alteration in currently known AD biomarkers. 4)  Low mtDNA content in CSF distinguishes patients diagnosed with AD from either controls or patients with fronto-temporal lobar degeneration. These findings indicate that the amount of circulating cell-free mtDNA content in CSF may be a novel biomarker for the early detection of AD in the preclinical stage of AD. Moreover, the observation that low mtDNA content in the CSF is associated with both sporadic and familial forms of AD suggests that, independently of the etiology, regulation of mtDNA content is a converging factor in the pathophysiology of AD.

MedicalResearch.com Interview with: Steve Estus PhD Dept. of Physiology University of Kentucky Office: Room 332 Sanders-Brown Building 800 S. Limestone Street Lexington, KY 40536-0230 MedicalResearch.com: What are the main findings of the study? Answer: We report evidence for the function of a Alzheimer's genetic  risk factor.  This protective allele of the polymorphism decreases the splicing efficiency of exon 2 in CD33, a receptor protein that regulates microglial activation.  Loss of exon 2 appears to produce a dormant CD33 protein, resulting in increased microglial phagocytosis activity.  Overall, these findings confirm and extend recent papers in Neuron and Nature Neuroscience  (discussed further in our report) that described decreased CD33 activity with the protective SNP allele.

TITLE: Retinal Vessel Caliber and Lifelong Neuropsychological Functioning An international research team from the USA, UK, Singapore and New Zealand reports that the size of the blood vessels in the back of the eye can indicate the health of the brain of people approaching midlife (age 38 years), years before age-related declines in brain functioning. PUBLICATION SOURCE: Psychological Science, advance online publication date, May 2013.   BACKGROUND:
  • Young people who score low on IQ tests, tend to be at higher risk for diseases in later life, and even tend to die younger.
  • One plausible explanation for this link is that intelligence tests assess brain health.
  • Digital retinal imaging is a relatively new and non-invasive method to visualize the small blood vessels in the retina, at the back of the eye. The small vessels in the eye may reflect the conditions of the vessels inside the brain because both eye and brain vessels share similar size, structure and function. Thus, retinal imaging can provide a window to study the health of the brain in living humans.
  • We studied the link between retinal vessel width and intelligence tests scores in the representative Dunedin birth cohort of 1000 New Zealanders born in 1972-73, and followed for 38 years with repeated assessments.
  • Using a digital fundus camera, which can photograph the interior surface of the eye, we were able to assess the size of the small blood-vessels in the retina, namely, the arterioles and venules (the small branches of the arteries and veins). We also administered intelligence tests in childhood and adulthood.
THE FINDING:
  • We found that study members who presented with wider venules had poorer intelligence tests scores at midlife (age 38 years). This finding held up independently of potential factors that may explain this link, such as low socio-economic status, smoking, or diabetes.
  • Moreover, wider venules in the eye were linked with lower childhood IQ that had been tested 25 years earlier.

MedicalResearch.com eInterview with: John Hart, M.D. Medical Science Director at the Center for BrainHealth Jane and Bud Smith Distinguished Chair Cecil Green Distinguished Chair The University of Texas at DallasJohn Hart, M.D. Medical Science Director at the Center for BrainHealth Jane and Bud Smith Distinguished Chair Cecil Green Distinguished Chair The University of Texas at Dallas MedicalResearch.com: What are the main findings of the study? Dr. Hart: Football players often sustain numerous concussive and subconcussive impacts—head impacts that do not elicit neurologic symptoms that may lead to white matter damage. We evaluated a population of retired NFL players in order to study the relationship between white matter integrity and the manifestation of depressive symptoms. We identified, for the first time, a correlation between depression and white matter abnormalities in former players with a remote history of concussion using diffusion tensor imaging (DTI). Our data demonstrated a significant association between white matter integrity, as measured by DTI Fractional Anisotropy (FA), and the presence as well as severity of depressive symptoms in retired NFL athletes with a history of concussive or subconcussive impacts. We also found that dysfunction of the anterior aspect of the corpus callosum (forceps minor) and its projections to the frontal lobe can identify those with depression with 100% sensitivity and 95% specificity.

Dr Sunjeev Kamboj Lecturer in Clinical Psychology Co-ordinator for International DClinPsy Trainees http://www.ucl.ac.uk/clinical-psychology/index.htm MedicalResearch.com: What are the main findings of the study? Dr. Kamboj: Using a fairly standard approach for this type of research, we measured the frequency of intrusive memories in normal, healthy women after they watched a series of video clips containing distressing scenes. We also measured baseline levels of progesterone and estrogen. We tested three groups of women who, while similar in all respects such age, education level, as well as how they responded to the film, differed in terms of the stage of the menstrual cycle they were in. Our key finding was that women in the 'early luteal phase' - which occurs in the third week of the cycle - had three times as many intrusive memories about the video than women in the first two weeks or fourth week of the cycle.

Kathryn L. Humphreys, M.A., Ed.M. Clinical Psychology Doctoral Student UCLA Department of Psychology 1285 Franz Hall, Box 951563 Los Angeles, CA 90095MedicalResearch.com eInterview with Kathryn L. Humphreys, M.A., Ed.M. Clinical Psychology Doctoral Student UCLA Department of Psychology 1285 Franz Hall, Box 951563 Los Angeles, CA 90095 MedicalResearch.com: What are the main findings of the study? Response: Our primary question was to answer whether the use of stimulant medication in the treatment of ADHD was associated with increased or decreased risk for a variety of substance use (ever tried) and substance use disorder (abuse or dependence) outcomes (alcohol, cocaine, marijuana, nicotine, and non-specific drug use). Prior research from individual studies of children have provided mixed evidence (i.e., some found medication increased later risk, some found medication decreased risk, and still others found no difference in risk). We examined available longitudinal studies (i.e., medication treatment preceded measurement of substance outcome) together using meta-analysis, a technique that aggregates findings from a number of studies, in order to examine this question in a much larger sample of individuals. Our main finding was that children with ADHD who received medication treatment did not differ in risk for lifetime substance use or abuse or dependence compared to those children with ADHD who did not receive medication treatment.

Scrutton ScD FRSC FSB Director Manchester Institute of Biotechnology EPSRC Established Career Fellow |Faculty of Life Sciences | Manchester Institute of Biotechnology | University of Manchester | Manchester | M1 7DN | UK | MedicalResearch.com: What are the main findings of your study? Dr. Scrutton: A major breakthrough has been made by our team of researchers seeking treatments for degenerative illnesses such as Parkinson's Disease. We have detailed how an enzyme in the brain interacts with a drug-like lead compound directed against Huntington's Disease (but also with major implications for Alzheimer’s and Parkinson’s diseases) to inhibit its activity. The work – which solved the molecular structure of a crucial brain enzyme called kynurenine 3-monooxygenase – opens the door to effective treatment for neurodegenerative diseases such as Huntington's, Alzheimer's and Parkinson's. The main findings not only describe the molecular details of the enzyme, but also how it interacts with a lead drug compound that inhibits the natural activity of the enzyme. (more…)

Dr. Nordström: We have found that low cognitive function and factors related to low socioeconomic status and intoxications are strong independent risk factors for mild traumatic brain injury in men. Medical Research.com: Were any of the findings unexpected? Dr. Nordström:  Our knowledge of risk factors that predispose people to sustaining such injury is limited. Previous research has inferred that mild traumatic brain injuries have important long-term consequences on cognitive function. However, we found similar deficits in cognitive function in subjects that sustained a mild traumatic brain injury before and after cognitive testing. Thus our data suggest that the injury itself may not reduce cognitive function. (more…)
