Several studies have linked specific learning disorders (SLDs) with suicidal ideation, but less is known about the disorders' association with suicide attempts. This gap in the literature is addressed via the 2012 nationally representative Canadian Community Health Survey ( n = 21,744). The prevalence of lifetime suicide attempts among those with an SLD was much higher than those without (11.1% vs. 2.7%, p < .001). In comparison with their peers without SLDs, adults with SLDs had 46% higher odds of having ever attempted suicide, even after adjusting for most known risk factors (e...

Primary motor cortex (M1) plasticity is involved in motor learning and stroke motor recovery, and enhanced by increasing monoaminergic transmission. Age impacts these processes but there is a paucity of systematic studies on the effects of monoaminergic drugs in older adults. Here, in ten older adults (age 61+ 4 years, 4 males), we determine the effects of a single oral dose of carbidopa/levodopa (DOPA), d-amphetamine (AMPH), methylphenidate (MEPH) and placebo (PLAC) on M1 excitability and motor training-induced M1 plasticity...

Acquired equivalence (AE) is a form of feedback-based associative learning where the subject learns that two or more stimuli are equivalent in terms of being mapped onto the same outcomes or responses. While several studies dealt with how various neurological and psychiatric conditions affect performance on AE tasks (typically with small populations), studies dealing with AE in healthy subjects are rare, and no study has ever made an attempt to plot the development of this form of learning from the childhood through adulthood...

Incidental memory may reflect a form of learning in everyday life, although it is not consistently evaluated during standard neuropsychological evaluations. Further validation of a recently created measure of verbal Incidental Learning (IL) from the Wechsler Adult Intelligence Scale-IV is necessary to understand the utility of such a measure in clinical settings. Sixty-eight adults aged 50 to 89 were recruited from a Cognitive Disorders Clinic while receiving a standard neuropsychological assessment, along with two additional measures of IL...

The functional role of genetic variants in glia in the pathogenesis of psychiatric disorders remains poorly studied. Disrupted-In-Schizophrenia 1 (DISC1), a genetic risk factor implicated in major mental disorders, has been implicated in regulation of astrocyte functions. As both astrocytes and DISC1 influence adult neurogenesis in the dentate gyrus (DG) of the hippocampus, we hypothesized that selective expression of dominant-negative C-terminus truncated human DISC1 (mutant DISC1) in astrocytes would affect adult hippocampal neurogenesis and hippocampus-dependent behaviors...

Modern intensive care units (ICUs) collect large volumes of data in monitoring critically ill patients. Clinicians in the ICUs face the challenge of interpreting large volumes of high-dimensional data to diagnose and treat patients. In this work, we explore the use of Hierarchical Dirichlet Processes (HDP) as a Bayesian nonparametric framework to infer patients' states of health by combining multiple sources of data. In particular, we employ HDP to combine clinical time series and text from the nursing progress notes in a probabilistic topic modeling framework for patient risk stratification...

We designed a safety and health curriculum for dairy immigrant workers aiming to increase knowledge, encourage safe behavior, and reduce worker communication inequalities to prevent occupational injury and diseases. The design is largely based on the Taxonomy of Significant Learning and incorporated behavioral and adult learning theories and principles of occupational hazard control. Trainings were implemented with 836 Spanish-speaking workers from 67 farms in Wisconsin. Sixty-seven percent of workers reported never being trained before in dairy safety, 65% of these worked in dairy for 5 or fewers years, and 26% of workers reported being ever injured while working on dairy...

CONTEXT: Hypertension is a common and costly risk factor for cardiovascular disease, but just over half of all adults with hypertension have their blood pressure controlled nationally. In Minneapolis-St Paul, Minnesota, the rate of hypertension control is approximately 70% despite a rate of hypertension control similar to the national average as recently as the first half of the 1990s. OBJECTIVE: The purposes of this study were to identify factors in Minneapolis-St Paul and state-level policies and programs in Minnesota that may have contributed to the more rapid increase in blood pressure control there than that in the rest of the nation and to identify factors that can potentially be replicated in other jurisdictions...

Adult dentate gyrus (DG) neurogenesis is important for hippocampal-dependent learning and memory, but the role of new neurons in addiction-relevant learning and memory is unclear. To test the hypothesis that neurogenesis is involved in the vulnerability to morphine addiction, we ablated adult DG neurogenesis and examined morphine self-administration (MSA) and locomotor sensitization. Male Sprague-Dawley rats underwent hippocampal-focused, image-guided X-ray irradiation (IRR) to eliminate new DG neurons or sham treatment (Sham)...

Psychiatric disorders are relatively frequent comorbidities in epilepsy and they have an impact on morbidity, mortality, and quality of life. This is a report from the Task Force on Education of the ILAE Commission on Neuropsychiatry based on a survey about educational needs of epileptologists regarding management of the psychiatric comorbidities of epilepsy. The Task Force designed a quantitative questionnaire to survey the self-perceived confidence of child and adult epileptologists and psychiatrists in managing major psychiatric comorbidities of epilepsy to identify: (1) critical areas of improvement from a list of skills that are usually considered necessary for effective management of these conditions, and (2) the preferred educational format for improving these skills...

We first review fundamental insights into anti-ranavirus immunity learned with the Xenopus laevis/ranavirus FV3 model that are generally applicable to ectothermic vertebrates. We then further investigate FV3 genes involved in immune evasion. Focusing on FV3 knockout (KO) mutants defective for a putative viral caspase activation and recruitment domain-containing (CARD)-like protein (Δ64R-FV3), a β-hydroxysteroid dehydrogenase homolog (Δ52L-FV3), and an immediate-early18kDa protein (FV3-Δ18K), we assessed the involvement of these viral genes in replication, dissemination and interaction with peritoneal macrophages in tadpole and adult frogs...

BACKGROUND: Volume-to-outcome data have been studied in several complex surgical procedures, demonstrating improved outcomes at higher volume centers. Laparoscopic lysis of adhesions (LLOA) for small bowel obstruction (SBO) may result in better outcomes, but there is no information on the learning curve for this potentially complex case. This study evaluates the effect of institutional procedural volume on length of stay (LOS), outcomes, and costs in LLOA for SBOs. MATERIALS AND METHODS: The Nationwide Inpatient Sample data set between 2000 and 2013 was queried for discharges for a diagnosis of SBO involving LLOA in adult patients...
