Psychometric Properties of Computerized Cognitive Tools and Standard Neuropsychological Tests Used to Assess Sport Concussion: A Systematic Review.

Athletic programs are more frequently turning to computerized cognitive tools in order to increase efficiencies in concussion assessment. However, assessment using a traditional neuropsychological test battery may provide a more comprehensive and individualized evaluation. Our goal was to inform sport clinicians of the best practices for concussion assessment through a systematic literature review describing the psychometric properties of standard neuropsychological tests and computerized tools.

A pilot protocol to assess the feasibility of a virtual multiple crossover, randomized controlled trial design using methylphenidate in mild cognitive impairment.

Background: The conventional clinical trial design in Alzheimer's disease (AD) and AD-related disorders (ADRDs) is the parallel-group randomized controlled trial. However, in heterogeneous disorders like AD/ADRDs, this design requires large sample sizes to detect meaningful effects in an "average" patient. They are very costly and, despite many attempts, have not yielded new treatments for many years.

Experiences of Women with Postpartum Depression Participating in a Support Group Led by Mental Health Providers.

Purpose: The purpose of this study was to explore experiences of women currently with or at high risk for developing postpartum depression (PPD) who were participating in a postpartum support group facilitated by mental health providers.

Study Design And Methods: Using a qualitative design, women ≥18 years of age, who had given birth within the past 2 years, and who were currently attending, or had attended the PPD support group within the past year were invited to participate. The women provided demographic data and participated in a semistructured face-to-face interview.

The vulnerability of self-reported disability measures to malingering: a simulated ADHD study.

Objective: Making diagnostic and accommodation decisions for potential Attention-Deficit/Hyperactivity Disorder (ADHD) in adults is difficult, as the assessor often relies more on self-reported symptoms and functional disability than in childhood evaluations. Malingering of ADHD occurs frequently in the educational setting and for a variety of reasons, including the potential benefits of access to stimulant medications and academic accommodations.

Method: The present study utilized a simulation design to examine the potential for malingering of self-reported functional disability on the World Health Organization Disability Schedule 2.

Further Validation of the Conner's Adult Attention Deficit/Hyperactivity Rating Scale Infrequency Index (CII) for Detection of Non-Credible Report of Attention Deficit/Hyperactivity Disorder Symptoms.

Objective: Attention deficit/hyperactivity disorder (ADHD) can be easily presented in a non-credible manner, through non-credible report of ADHD symptoms and/or by non-credible performance on neuropsychological tests. While most studies have focused on detection of non-credible performance using performance validity tests, there are few studies examining the ability to detect non-credible report of ADHD symptoms. We provide further validation data for a recently developed measure of non-credible ADHD symptom report, the Conner's Adult ADHD Rating Scales (CAARS) Infrequency Index (CII).

[Formula: see text] Effects of screening for postconcussive syndrome (PCS) on PCS symptom self-report and neuropsychological test performance.

Objective: Many non-neurological factors are related to postconcussive syndrome (PCS) symptom report and neuropsychological test performance in mild traumatic brain injury (mTBI). Use of mTBI screening instruments may also contribute to report of PCS symptoms and neuropsychological performance. We examined the impact of randomized PCS screening feedback on PCS symptom report and neuropsychological performance in 152 young adults with no history of mTBI.

Improving immunization coverage in a rural school district in Pierce County, Washington.

Washington State has some of the highest percentages of school immunization exemptions in the country. We compared school immunization records in a rural school district in Pierce County, Washington, to immunization records in the state immunization information system (IIS) and parent-held records. Correcting school immunization records resulted in an increase in the number of students classified as fully immunized from 1,189 to 1,564 (p < .

An Affinity Capture Elution (ACE) assay for detection of anti-drug antibody to monoclonal antibody therapeutics in the presence of high levels of drug.

Monoclonal antibody therapeutics typically have relatively long half-lives and can be dosed at high levels. Although formation of anti-drug antibodies (ADA) is relatively rare, detection of these antibodies can be very difficult in the presence of high circulating levels of drug. Typically these ADA are detected by bridging ELISAs which can be very sensitive to even low levels of drug.

In vitro and in vivo characterization of p-amino-phenethyl-m-trifluoromethylphenyl piperazine (PAPP), a novel serotonergic agonist with anthelmintic activity against Haemonchus contortus, Teladorsagia circumcincta and Trichostrongylus colubriformis.

The neurotransmitter serotonin (5-hydroxy tryptamine or 5HT) regulates key physiological processes in nematodes such as locomotion and feeding. PAPP (p-amino-phenethyl-m-trifluoromethylphenyl piperazine) is a known agonist of the 5-HT(1Hc) receptor of the barber pole worm, Haemonchus contortus. In this study, PAPP was highly active against L3-stage larvae of H.

Development and validation of a drug activity biomarker that shows target inhibition in cancer patients receiving enzastaurin, a novel protein kinase C-beta inhibitor.

Purpose: To evaluate the effects of the novel protein kinase C (PKC) inhibitor enzastaurin on intracellular phosphoprotein signaling using flow cytometry and to use this approach to measure enzastaurin effects on surrogate target cells taken from cancer patients that were orally dosed with this agent.

Experimental Design: The activity of PKC was assayed in intact cells using a modification of published techniques. The U937 cell line and peripheral blood mononuclear cells were stimulated with phorbol ester, fixed, permeabilized, and reacted with an antibody specific for the phosphorylated forms of PKC substrates.

Glucose stimulates the association of Crk with p130Cas in pancreatic beta cells.

Objectives: Previously, we demonstrated glucose-induced beta-cell tyrosine phosphorylation of p130Cas, a protein containing 15 YXXP repeats that can become tyrosine phosphorylated and bind Src-homology 2 (SH2)-containing proteins. In light of the importance of p130Cas in other cell types, we determined which beta-cell proteins exhibited glucose-induced association with p130Cas.

Methods: beta cells were stimulated with glucose and/or the muscarinic agonist carbachol to determine which SH2-containing adapter proteins underwent glucose-induced association with p130Cas.

Characterization of a novel G-protein coupled receptor from the parasitic nematode H. contortus with high affinity for serotonin.

The neurotransmitter serotonin (5HT) has been shown to modulate mobility, feeding, egg-laying, and defecation behaviors in the saprophytic nematode Caenorhabditis elegans. Although the effects of serotonin on these behaviors in parasitic nematodes is under study, little is known about the diversity, ontogeny, signaling, and pharmacology of serotonin receptors in these organisms. In an effort to increase our understanding of this system, we cloned and characterized a novel cDNA (5HT1Hc) from the parasitic nematode Haemonchus contortus that has high amino acid sequence homology with known G-protein coupled 5HT1-receptors from invertebrates and vertebrates.
