Florien Boel MSc VU University Medical Center Department of Medical Psychology Amsterdam, The Netherlands MedicalResearch.com Interview with: Florien Boel MSc VU University Medical Center Department of Medical Psychology Amsterdam, The Netherlands Medical Research: What are the main findings of the study? Answer: In postmenopausal breast cancer patients, endocrine therapy is widely used, and often for many years on end. Endocrine therapy is thought to have an effect on cognitive functioning, but previous studies have not yet accounted for the possible influence of the diagnosis of cancer and subsequent anxiety, depression or fatigue on cognitive performance. In addition, the cognitive effects of endocrine therapy after long-term use are still mostly unknown. Therefore, we compared cognitive functioning of postmenopausal breast cancer patients who underwent surgery and/or radiotherapy (N=43) with the cognitive performance of women who also received adjuvant endocrine therapy (tamoxifen) (N=20) and a group of healthy matched individuals (N=44). In accordance with the literature, we found that especially cognitive domains that rely heavily on verbal abilities (verbal memory and fluency) seem to be at risk for deterioration during long-term treatment (~2.5 years) with tamoxifen.

Author Interviews, Brain Injury, JAMA / 17.07.2014

MedicalResearch.com Interview with: Emmanuel Lagarde Director of Research at INSERM, France  Medical Research: What are the main findings of the study?  Dr. Lagarde: Concussion accounts for more than 90 percent of all traumatic brain injuries, although little is known about prognosis for the injury. The symptoms cited as potentially being part of post concussion syndrome fall into three areas: cognitive, somatic and emotional. But the interpretation of symptoms after concussion should also take into account that injuries are often sustained during psychologically distressing events which can lead to Posttraumatic Stress Disorder.    Medical Research: Were any of the findings unexpected?  Dr. Lagarde: Yes, as we were expecting to observe long term (3-month) symptoms following brain injury, but few were found to be specific : most of them were as frequent among patients with other injuries.  Medical Research: What should clinicians and patients take away from your report?  Dr. Lagarde: It seems as if there is little evidence of the existence of a specific syndrome following mild traumatic brain injury. However, patients who experienced a concussion are at risk of  another well-known syndrome called Posttraumatic Stress Disorder, which is associated with the distressing event that led to the injury.  Medical Research: What recommendations do you have for future research as a result of this study?  Dr. Lagarde: The classification system of symptoms following mild brain injury should be revisited as our results are challenging the very relevance of the DSM-V post concussion syndrome.

MedicalResearch.com interview with: Lee M. Hampton, MD, MSc: Division of Healthcare Quality Promotion Centers for Disease Control and Prevention Atlanta, Georgia Medical Research: What are the main findings of the study? Dr. Hampton: The study, which used CDC's national outpatient adverse drug event surveillance system (NEISS-CADES), found that there are almost 90,000 estimated annual emergency department visits by adults for adverse drug events from therapeutic use of antipsychotics, antidepressants, sedatives and anxiolytics, lithium salts or stimulants between 2009 and 2011. Almost one in five of those emergency department visits (19.3%) resulted in hospitalization. Sedatives and anxiolytics, antidepressants, and antipsychotics each caused 20,000 to 30,000 emergency department visits annually. However, relative to how often each of these types of medications was prescribed at outpatient visits, antipsychotics and lithium salts were more likely to cause emergency department visits for adverse drug events than were sedatives, stimulants, and antidepressants. Antipsychotics caused 3.3 times more emergency department visits for adverse drug events than sedatives, 4.0 times more emergency department visits than stimulants, and 4.9 times more emergency department visits than antidepressants relative to their outpatient use. Out of the 83 specific drugs the study looked at, ten drugs were implicated in nearly 60% of the emergency department visits for ADEs from therapeutic use of antipsychotics, antidepressants, sedatives and anxiolytics, lithium salts or stimulants. Zolpidem was implicated in nearly 12% of all such emergency department visits and 21% of such emergency department visits involving adults aged 65 years or older, more than any other antipsychotic, antidepressant, sedative or anxiolytic, lithium salt or stimulant.

Dr. Cassidy: We found that adults with late diagnosis of Asperger Syndrome (31 years on average), were at significantly higher risk of contemplating suicide during their lifetime (66%) than those from the general UK population (17%), and a sample of patients with Psychosis (59%). We also found that adults diagnosed with Asperger Syndrome with a history of depression, were significantly more likely to experience suicidal thoughts, and suicide plans or attempts, than those with Asperger Syndrome without a history of depression.  A higher level of autistic traits was also a significant risk factor for having planned or attempted suicide.

Dr. Vemuri: Lifetime intellectual enrichment might delay the onset of cognitive impairment and be used as a successful preventive intervention to reduce the impending dementia epidemic. We studied two non-overlapping components of lifetime intellectual enrichment: education/occupation-score and mid/late-life cognitive activity measure based on self-report questionnaires. Both were helpful in delaying the onset of cognitive impairment but the contribution of higher education/occupation was larger. (more…)
Author Interviews, Cognitive Issues, Long Term Care / 23.06.2014

Regina Shih PhD Senior Behavioral Scientist at the RAND Corporation.MedicalResearch.com Interview with: Regina Shih PhD Senior Behavioral Scientist at the RAND Corporation.   MedicalResearch: What are the main findings of the study? Dr. Shih: RAND identified 25 high-impact policy options to improve the delivery, workforce, and financing of long term care, with a specific eye toward those with dementia and their caregivers. Undertaking these 25 policy options would achieve five goals: increasing public awareness of dementia and its signs and symptoms; improving access to long-term care; promoting high-quality, person-centered care like that offered at Lakeside Manor; providing better support for family caregivers; and reducing the burden of dementia costs on individuals and their families. Of these 25 policy options, we identified four unique options that have never been identified in any national plan on dementia or long-term care. This is likely because we focused on the intersection between dementia and long-term care, rather than just one or the other. And, rather than only focusing on actions that federal agencies can take, we identified policy options by interviewing 30 different stakeholders in the public and private sectors at the local, state, and national levels. These unique, high-impact policy options have to do with
  • Linking private health insurance with private long-term care insurance;
  • Including home and community-based services in state Medicaid plans;
  • Establishing cross-setting teams focused on returning the person with dementia to the community;
  • Expanding financial compensation to family caregivers.

Grégoire Rey Directeur du CépiDc CépiDc-Inserm Hopitâl Bicêtre FranceMedicalResearch.com Interview with: Grégoire Rey Directeur du CépiDc CépiDc-Inserm Hopitâl Bicêtre France MedicalResearch: What are the main findings of the study? Dr. Rey: We found that, between 2000 and 2010, unemployment and suicide rates were globally associatedin eight Western European countries (Austria, Finland, France, Germany, the Netherlands, Spain, Sweden, and the UK). However, this ecological association was weak (0.3% increase in suicide rate for a 10% increase in unemployment rate). Across countries, it was inconsistently confounded by the effect of other concomitant features of the economic crisis. MedicalResearch: Were any of the findings unexpected? (more…)

Dr. Shah: We discovered that in a group of patients who were undergoing heart evaluation with coronary angiography, symptoms of depression predicted increased risk of coronary artery disease and death in women aged 55 years or less. This relationship was stronger in these women than older women, as well as in men aged 55 years or less. Over 1 in 4 women aged 55 years or less had moderate to severe depression, which was higher than any other group; these women had over twice the risk of having heart disease or dying over the next 3 years compared to those with none or mild depression.

Dr. Krista Huybrechts MD PhD Brigham & Women’s Hospital Department of Medicine Division of Pharmacoepidemiology & Pharmacoeconomics Boston, MA 02120MedicalResearch.com Interview Invitation Dr. Krista Huybrechts MD PhD Brigham & Women’s Hospital Department of Medicine Division of Pharmacoepidemiology & Pharmacoeconomics Boston, MA 02120 MedicalResearch: What are the main findings of the study? Dr. Huybrechts: In this cohort study including 949,504 pregnant women enrolled in Medicaid, we examined whether the use of selective serotonin reuptake inhibitors (SSRIs) and other antidepressants during the first trimester of pregnancy is associated with increased risks for congenital cardiac defects. In order to control for potential confounding by depression and associated factors, we restricted the cohort to women with a depression diagnosis and used propensity score adjustment to control for depression severity and other potential confounders. We found no substantial increased risk of cardiac malformations attributable to SSRIs. Relative risks for any cardiac defect were 1.25 (95%CI, 1.13-1.38) unadjusted, 1.12 (1.00-1.26) depression-restricted, and 1.06 (0.93-1.22) depression-restricted and fully-adjusted. We found no significant associations between the use of paroxetine and right ventricular outflow tract obstruction (1.07, 0.59-1.93), or the use of sertraline and ventricular septal defects (1.04, 0.76-1.41); two potential associations that had been of particular concern based on previous research findings.

Michele Jacob, Ph.D. Professor of Neuroscience Sackler School of Graduate Biomedical Sciences Tufts UniversityMedicalResearch.com Interview with Michele Jacob, Ph.D. Professor of Neuroscience Sackler School of Graduate Biomedical Sciences Tufts University MedicalResearch: What are the main findings of the study? Dr. Jacob: Autistic-like behaviors and cognitive impairments associate with loss of the Adenomatous Polyposis Coli (APC) gene.  We deleted APC chiefly from excitatory neurons in the mouse developing forebrain; the mice exhibited changes in synapse maturation and density, reduced social interest, increased repetitive behaviors, and learning deficits.  In addition, we found  molecular changes that define a novel role for APC in linking to and regulating the levels of particular proteins that function in synaptic adhesion complexes and signaling pathways that are required for normal learning and memory consolidation.

Professor Louis Appleby Professor of Psychiatry C.B.E The University of Manchester in the UKMedicalResearch.com Interview with: Professor Louis Appleby Professor of Psychiatry C.B.E The University of Manchester in the UK   MedicalResearch: What are the main findings of the study? Professor Appleby: “Patients with mental illness are two and a half times more likely to be victims of homicide than people in the general population according to our research published in The Lancet Psychiatry today. “In this study, the National Confidential Inquiry into Suicide and Homicide by People with Mental Illness (NCI), based at The University of Manchester, examined data on the victims and perpetrators of all homicides in England and Wales between January, 2003 and December, 2005. We found that during the 3-year study period, 1496 people were victims of homicide, and 6% (90) of them had been under the care of mental health services in the year before their death. A third (29) of these patient victims were killed by other patients with mental illness. In 23 homicides in which the victim was a mental health patient killed by another mental health patient, the victim and the perpetrator were known to each other either as partners (9, 35%), family members (4, 15%), or acquaintances (10, 38%). In 21 of these 23 cases, both the victims and perpetrators were undergoing treatment at the same National Health Service Trust. Alcohol and drug misuse (victims 66%, perpetrators 93%) and a history of violence (victims 24%, perpetrators 24%) were common among both patient victims and perpetrators. The study also found that in the 3 years to 2005, 213 mental health patients were convicted of homicide—accounting for 12% of all homicide convictions.” (more…)

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.

Evan Thacker PhD Brigham Young UniversityMedicalResearch.com Interview with: Evan Thacker PhD Brigham Young University Provo, Utah   MedicalResearch: What are the main findings of the study? Dr. Thacker: In this study of over 17,000 American adults aged 45 and above, we first measured people’s cardiovascular health based on their smoking habits, diet, physical activity, body weight, blood pressure, blood cholesterol, and blood sugar. We then tracked these people for several years with cognitive function tests which measure memory and thinking abilities. The main finding of our study was that people who had the lowest levels of cardiovascular health at the beginning of the study were more likely to experience cognitive impairment – poor performance on the cognitive function tests – at the end of the study. People who had medium to high levels of cardiovascular health were less likely to experience cognitive impairment. (more…)

MedicalResearch.com Interview with: Emma Maund, PhD student Nordic Cochrane Centre Copenhagen, Denmark

MedicalResearch: What are the main findings of the study:

Answer: For statisticians to analyse adverse events recorded in a clinical trial, it is necessary that events described by the original investigators are coded to terms in a specialised medical coding dictionary. Our study assessed the effects of coding and coding conventions on summaries and tabulations of adverse events data on suicidality within clinical study reports of nine randomised controlled trials of duloxetine for the treatment of major depressive disorder. Trials used either the medical coding dictionary COSTART (Coding Symbols for a Thesaurus of Adverse Reaction Terms) or the larger and more recent dictionary MedDRA (Medical Dictionary for Regulatory Activities). We found suicides were clearly identifiable in all formats of adverse event data. Suicide attempts in tables included both definitive and provisional diagnoses. Suicidal ideation and preparatory behaviour were obscured in some tables owing to the lack of specificity of the medical coding dictionary, especially in trials using COSTART where the closest matching term available was depression.

Dr. Anders Nykjaer MD, PhD Mayo Clinic in Florida and Aarhus University in DenmarkMedicalResearch.com Interview with: Dr. Anders Nykjaer MD, PhD Mayo Clinic in Florida and Aarhus University in Denmark MedicalResearch: What are the main findings of the study? Dr. Nykjaer: It is well known that ADHD is a complex condition caused by a number of factors including genetic and environment. However, approximately 75% etiology is considered to be genetic and a large body of investigations suggests that it is multiple genes each with a moderate effect that is responsible for conferring susceptibility to ADHD. We have here found one single gene the dysfunction of which is sufficient to trigger the disease.  The gene encodes a receptor, SorCS2, which ensures correct wiring our reward system during embryonic development. Malfunction of the receptor causes ADHD-like symptoms in mice. It is well accepted that ADHD predisposes to psychiatric disorders and genetic reports have linked variations in the SorCS2 gene with schizophrenia. Studies are currently ongoing to evaluate if mutations disrupting the function of SorCS2 may also result in schizophrenia. If this is the case we have come closer to an explanation for the link between ADHD and psychiatric disorders. In the future when prenatal genetic screening becomes established, non-sense mutations in the SorCS2 gene can be used to predict that the child will develop ADHD with 100% certainty.   (more…)

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.

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.

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. Holz: Using data from a prospective community sample followed since birth, we investigated the impact of prenatal maternal smoking on lifetime Attention-Deficit/ Hyperactivity Disorder (ADHD) symptoms and on brain structure and inhibitory control assessed with Magnetic Resonance Imaging in the adult offspring. Those who were prenatally exposed to tobacco not only exhibited more ADHD symptoms, but also showed decreased activity in the inhibitory control network encompassing the inferior frontal gyrus as well as the anterior cingulate cortex. Activity in these regions was inversely related to lifetime ADHD symptoms and novelty seeking, respectively. In addition volume in the inferior frontal gyrus was decreased in these participants.
