Impact of the host immune response on the development of equine herpesvirus myeloencephalopathy in horses.

Herpesviruses establish a well-adapted balance with their host's immune system. Despite this co-evolutionary balance, infections can lead to severe disease including neurological disorders in their natural host. In horses, equine herpesvirus 1 (EHV-1) causes respiratory disease, abortions, neonatal foal death and myeloencephalopathy (EHM) in ~10 % of acute infections worldwide.

Mindfulness in the Clinic Waiting Room May Decrease Pain: Results from Three Pilot Randomized Controlled Trials.

Mindfulness interventions can improve a broad range of patient outcomes, but traditional mindfulness-based interventions are time and resource intensive. Emerging evidence indicates brief, single-session mindfulness interventions can also improve patient outcomes, and brief mindfulness interventions can be embedded into medical care pathways with minimal disruption. However, the direct impact of a brief mindfulness intervention on patients' pain while waiting in the clinic waiting room remains unexamined.

Physiologic Treatment of Severe Hypertension in Pregnancy and Postpartum.

We aimed to evaluate physiologic treatment of severe hypertension. This was a retrospective cohort study of pregnant and postpartum patients with severe hypertension (systolic blood pressure [BP] 160 mm Hg or higher or diastolic BP 110 mm Hg or higher) treated with intravenous labetalol or hydralazine at a single tertiary care center between 2013 and 2018. Patients were classified as having physiologic treatment if they had hyperdynamic physiology (pulse pressure 65 mm Hg or higher) and received labetalol or had vasoconstrictive physiology (diastolic BP 100 mm Hg or higher) and received hydralazine.

Occipital Nerve Block Compared With Acetaminophen and Caffeine for Headache Treatment in Pregnancy: A Randomized Controlled Trial.

Objective: To evaluate the efficacy of occipital nerve block compared with standard care , defined as acetaminophen with caffeine, for treatment of acute headache in pregnancy.

Methods: We conducted a single-center, unblinded, parallel, randomized controlled trial of pregnant patients with headache and pain score higher than 3 on the visual rating scale. Patients with secondary headache, preeclampsia, or allergy or contraindication to study medications were excluded.

Measuring Caenorhabditis elegans Sensitivity to the Acetylcholine Receptor Agonist Levamisole.

At the neuromuscular junction (NMJ), the binding of the excitatory neurotransmitter acetylcholine (ACh) to postsynaptic receptors leads to muscle contraction. As in vertebrate skeletal muscle, cholinergic signaling in the body wall muscles of the model organism Caenorhabditis elegans is required for locomotion. Exposure to levamisole, a pharmacological agonist of one class of ACh receptors on the body wall muscles, causes time-dependent paralysis of wild-type animals.

Metabolic Alterations and WNT Signaling Impact Immune Response in HGSOC.

Purpose: Our study used transcriptomic and metabolomic strategies to determine the molecular profiles of HGSOC patient samples derived from primary tumor and ascites cells. These data identified clinically relevant heterogeneity among and within patients and highlighted global and patient-specific cellular responses to neoadjuvant chemotherapy (NACT).

Experimental Design: Tissue from 61 treatment-naïve patients with HGSOC were collected.

Using Subthreshold Vibratory Stimulation During Poststroke Rehabilitation Therapy: A Case Series.

Subthreshold vibratory stimulation to the paretic wrist has been shown to prime the sensorimotor cortex and improve 2-week upper extremity (UE) therapy outcomes. The objective of this work was to determine feasibility, safety, and preliminary efficacy of the stimulation over a typical 6-week therapy duration. Four chronic stroke survivors received stimulation during 6-week therapy.

Designing and Evaluating a Prediabetes Shared Decision Aid.

Background: Prediabetes is increasing in prevalence and is associated with risk of developing diabetes, heart disease, stroke, and retinopathy. Clinicians have limited tools to facilitate prediabetes discussions within primary care visits.

Purpose: 1) Develop a Patient and Stakeholder Advisory Committee (PASAC) to design, evaluate, and revise a prediabetes shared decision aid, and 2) evaluate the feasibility and experience of implementing the tool within primary care practice.

EMR 20006-012: A phase II randomized double-blind placebo controlled trial comparing the combination of pimasertib (MEK inhibitor) with SAR245409 (PI3K inhibitor) to pimasertib alone in patients with previously treated unresectable borderline or low grade ovarian cancer.

Objective: To compare the combination of a MEK inhibitor (pimasertib) and a PI3K inhibitor (SAR245409) to pimasertib alone in recurrent unresectable borderline/low malignant potential (LMP) or low-grade serous ovarian carcinoma (LGSOC), determining whether combination is superior.

Methods: Patients with previously treated, recurrent LMP or LGSOC with measurable disease received either combination of pimasertib (60 mg daily) + SAR245409 (SAR) (70 mg daily) or pimasertib alone (60 mg BID) until progression or unacceptable toxicity. Primary endpoint was objective response rate (ORR) by RECIST 1.

Evaluation of Step-Counting Interventions Differing on Intensity Messages.

Background: Step-counting interventions with discrepant intensity emphases may elicit different effects.

Methods: A total of 120 sedentary/low-active, postmenopausal women were randomly assigned to one of the following 3 groups: (1) 10,000 steps per day (with no emphasis on walking intensity/speed/cadence; basic intervention, 49 completers), (2) 10,000 steps per day and at least 30 minutes in moderate intensity (ie, at a cadence of at least 100 steps per minute; enhanced intervention, 47 completers), or (3) a control group (19 completers). NL-1000-determined steps and active minutes (a device-specific indicator of time at moderate+ intensity) were collected as process variables during the 12-week intervention.

Extending the platinum-free interval: The impact of omitting 2nd line platinum chemotherapy in intermediate platinum-sensitive ovarian cancer.

Objectives: Patients with epithelial ovarian cancer (EOC) recurring between 6 and 12 months after primary platinum chemotherapy have worse prognosis than those recurring in >12 months. Artificially prolonging the platinum-free interval (PFI) with cytotoxic chemotherapy was tested in MITO-8 with poor outcomes. This study aimed to determine the impact of using non-platinum or targeted therapy in 2nd line treatment of EOC patients recurring 6-12 months after completion of primary platinum-based chemotherapy.

Maternal Impression Management in the Assessment of Childhood Depressive Symptomatology.

Background: Self-report instruments are commonly used to assess for childhood depressive symptoms. Historically, clinicians have relied heavily on parent-reports due to concerns about childrens' cognitive abilities to understand diagnostic questions. However, parents may also be unreliable reporters due to a lack of understanding of their child's symptomatology, overshadowing by their own problems, and tendencies to promote themselves more favourably in order to achieve desired assessment goals.

Effectiveness of SmartMoms, a Novel eHealth Intervention for Management of Gestational Weight Gain: Randomized Controlled Pilot Trial.

Background: Two-thirds of pregnant women exceed gestational weight gain (GWG) recommendations. Because excess GWG is associated with adverse outcomes for mother and child, development of scalable and cost-effective approaches to deliver intensive lifestyle programs during pregnancy is urgent.

Objective: The aim of this study was to decrease the proportion of women who exceed the Institute of Medicine (IOM) 2009 GWG guidelines.

Evasion of immunosurveillance by genomic alterations of PPARγ/RXRα in bladder cancer.

Muscle-invasive bladder cancer (MIBC) is an aggressive disease with limited therapeutic options. Although immunotherapies are approved for MIBC, the majority of patients fail to respond, suggesting existence of complementary immune evasion mechanisms. Here, we report that the PPARγ/RXRα pathway constitutes a tumor-intrinsic mechanism underlying immune evasion in MIBC.

Reliability and Validity of a Novel Internet-Based Battery to Assess Mood and Cognitive Function in the Elderly.

Dementia is a chronic condition in the elderly and depression is often a concurrent symptom. As populations continue to age, accessible and useful tools to screen for cognitive function and its associated symptoms in elderly populations are needed. The aim of this study was to test the reliability and validity of a new internet-based assessment battery for screening mood and cognitive function in an elderly population.

WalkMore: a randomized controlled trial of pedometer-based interventions differing on intensity messages.

Background: Pedometer-based programs have elicited increased walking behaviors associated with improvements in blood pressure in sedentary/low active postmenopausal women, a population at increased risk of cardiovascular disease. Such programs typically encourage increasing the volume of physical activity with little regard for its intensity. Recent advances in commercially available pedometer technology now permit tracking of both steps/day and time in moderate (or greater) intensity physical activity on a daily basis.

Renoprotective effects of direct renin inhibition in glomerulonephritis.

The development of glomerulonephritis causes glomerular injury and renal dysfunction and is thought to increase renin release, thus activating the renin-angiotensin system (RAS). The aims of this study were to demonstrate activation of the intrarenal RAS and determine the effects of direct renin inhibition (DRI) on the progression of glomerulonephritis. Rats were treated with anti-Thy1.

Adiposity and physical activity are not related to academic achievement in school-aged children.

Objective: To investigate the hypotheses that in elementary school students: (1) adiposity and academic achievement are negatively correlated and (2) physical activity and academic achievement are positively correlated.

Methods: Participants were 1963 children in fourth to sixth grades. Adiposity was assessed by calculating body mass index (BMI) percentile and percent body fat and academic achievement with statewide standardized tests in 4 content areas.

The intensive care unit as an untapped learning resource: a student perspective.

The nursing student's clinical experience serves to form a bridge between the theoretical knowledge of the classroom and its application to patient care. The intensive care unit (ICU) has not traditionally been considered an ideal placement for undergraduate nursing students (Ballard & Trowbridge, 2004). However, in the fall of 2008, with a rise in enrolment, the school was faced with finding more clinical sites to accommodate our placement needs.

Memory for names test provides a useful confrontational naming task for aging and continuum of dementia.

There is an increasing need to develop new neuropsychometric tools sensitive enough to detect subtle declines in cognitive performance during normal aging, as well as to distinguish between normal aging and the earliest stages of dementia. In this study, we report our findings regarding a new confrontational naming test, the Memory for Names test. We conducted evaluations utilizing a cohort of 234 elderly participants who comprised a spectrum of cognitive function ranging from normal for age (Uniform Data Set Overall Appraisal = 2, Clinical Dementia Rating = 0) to demented (Clinical Dementia Rating = 1-2, Mini Mental Status Examination Total Score <25).

Development of an internet-based obesity prevention program for children.

Background: Childhood obesity is a growing problem, particularly in rural, Louisiana school children. Traditionally, school-based obesity prevention programs have used a primary prevention approach. Finding methods to deliver secondary prevention programs to large numbers of students without singling out overweight students has been a challenge.

Brønsted acid-catalyzed highly stereoselective arene-ynamide cyclizations. A novel keteniminium Pictet-Spengler cyclization in total syntheses of (+/-)-desbromoarborescidines A and C.

[reaction: see text] A Brønsted acid-catalyzed highly stereoselective arene-ynamide cyclization is described. These reactions constitute a keteniminium variant of Pictet-Spengler cyclizations, leading to efficient synthesis of nitrogen heterocycles and related alkaloids. Total syntheses of desbromoarborescidines A and C are illustrated here as first applications of this methodology.

RAD51-dependent break-induced replication in yeast.

A chromosome fragmentation assay was used to measure the efficiency and genetic control of break-induced replication (BIR) in Saccharomyces cerevisiae. Formation of a chromosome fragment by de novo telomere generation at one end of the linear vector and recombination-dependent replication of 100 kb of chromosomal sequences at the other end of the vector occurred at high frequency in wild-type strains. RAD51 was required for more than 95% of BIR events involving a single-end invasion and was essential when two BIR events were required for generation of a chromosome fragment.
