Estimating genetic parameters of digital behavior traits and their relationship with production traits in purebred pigs.

Background: With the introduction of digital phenotyping and high-throughput data, traits that were previously difficult or impossible to measure directly have become easily accessible, offering the opportunity to enhance the efficiency and rate of genetic gain in animal production. It is of interest to assess how behavioral traits are indirectly related to the production traits during the performance testing period. The aim of this study was to assess the quality of behavior data extracted from day-wise video recordings and estimate the genetic parameters of behavior traits and their phenotypic and genetic correlations with production traits in pigs.

Estimation of heritability with genomic information by method R.

Estimating heritabilities with large genomic models by established methods such as restricted maximum likelihood (REML) or Bayesian via Gibbs sampling is computationally expensive. Alternatively, heritability can be estimated indirectly by method R and by maximum predictivity, referred to as MaxPred here, at a much lower computing cost. By method R, the heritability used for predictions with whole and partial data is considered the best estimate when the predictions based on partial data are unbiased relative to those with the complete data.

Acupuncture for Combat-Related Posttraumatic Stress Disorder: A Randomized Clinical Trial.

Importance: Current interventions for posttraumatic stress disorder (PTSD) are efficacious, yet effectiveness may be limited by adverse effects and high withdrawal rates. Acupuncture is an emerging intervention with positive preliminary data for PTSD.

Objective: To compare verum acupuncture with sham acupuncture (minimal needling) on clinical and physiological outcomes.

Unfolded Von Willebrand Factor Binds Protein S and Reduces Anticoagulant Activity.

Protein S (PS), the critical plasma cofactor for the anticoagulants tissue factor (TF) pathway inhibitor (TFPI) and activated protein C (APC), circulates in two functionally distinct pools: free (anticoagulant) or bound to complement component 4b-binding protein (C4BP) (anti-inflammatory). Acquired free PS deficiency is detected in several viral infections, but its cause is unclear. Here, we identified a shear-dependent interaction between PS and von Willebrand Factor (VWF) by mass spectrometry.

Impact of blending the genomic relationship matrix with different levels of pedigree relationships or the identity matrix on genetic evaluations.

Evaluations using single-step genomic BLUP require blending the genomic relationship matrix () with a positive definite matrix to ensure nonsingularity for solving the mixed model equations. Many organizations blend with a proportion of the numerator relationship matrix for genotyped animals ( ) to improve stability and possibly add a residual polygenic effect. However, when nearly all the polygenic variance is explained by , blending with may cause inflation and add excess computing time; thus, blending with an identity matrix () multiplied by a small value may be a better solution.

Conceptualizing a Traditional Chinese Medicine and Pathology of Arousal Diagnostic and Pathophysiological Framework for Postacute Sequelae of COVID-19.

Introduction: The postacute sequelae of COVID-19 (PASC) is a serious heterogeneous condition that affects a significant minority of those who endured COVID-19. PASC involves multiple body systems and an illness trajectory that has stages now being identified in medical research.

Objective: Traditional Chinese Medicine (TCM) and acupuncture are well suited to conceptualize and treat PASC and other postviral conditions.

Improvement in Long-COVID Symptoms Using Acupuncture: A Case Study.

Background: The long-COVID syndrome (LCS), defined by residual symptoms from acute COVID-19 for <60 days, affects about one-third of all COVID survivors and is an emerging public health challenge. Empirical data about the range of symptoms or the utility of acupuncture alone for the LCS are very limited.

Case: This observational case study of a 46-year-old male with LCS was conducted to preliminarily define the range of symptoms, a Traditional Chinese Medicine (TCM) diagnostic structure, and evaluate the potential utility of prescribed acupuncture for LCS.

Evaluation of a Veterans Health Administration Whole Health for Mental Health Course for Clinicians.

Veterans experience mental health disorders at higher rates than their civilian counterparts and also experience multiple barriers to mental health services. The Veterans Health Administration (VA) has implemented a Whole Health approach to make health care more person-focused and oriented toward promotion of health-sustaining behavior. We conducted an evaluation to investigate the effects of a Whole Health for Mental Health (WHMH) course for clinicians that focuses on shifting the perspective to a system of care in which mental health is incorporated as a core part of whole-person care.

Comparison of Prolonged Exposure vs Cognitive Processing Therapy for Treatment of Posttraumatic Stress Disorder Among US Veterans: A Randomized Clinical Trial.

Importance: Posttraumatic stress disorder (PTSD) is a prevalent and serious mental health problem. Although there are effective psychotherapies for PTSD, there is little information about their comparative effectiveness.

Objective: To compare the effectiveness of prolonged exposure (PE) vs cognitive processing therapy (CPT) for treating PTSD in veterans.

Bias of the Immune Response to Does Not Alter the Ability of Neonatal Mice to Clear the Infection.

Newborn mice are unable to clear (PC) infection with the same efficiency as adults due, in part, to their inability to develop a robust immune response to infection until three weeks of age. It is known that infants tend develop a Th2 skewed response to antigen so we sought to determine whether a biased cytokine response altered the clearance of PC infection in neonatal mice. infection in neonatal mice resulted in increased IL-4 expression by CD4 T cells and myeloid cells, augmented IL-13 secretion within the airways and increased arginase activity in the airways, indicative of Th2-type responses.

Acupuncture for combat post-traumatic stress disorder: trial development and methodological approach for a randomized controlled clinical trial.

Background: Post-traumatic stress disorder (PTSD) is a significant public health problem, affecting approximately 7% of the general population and 13-18% of the combat Veteran population. The first study using acupuncture for PTSD in a civilian population showed large pre- to post-treatment effects for an empirically developed verum protocol, which was equivalent to group cognitive behavior therapy and superior to a wait-list control. The primary objective of this study is to determine both clinical and biological effects of verum acupuncture for combat-related PTSD in treatment-seeking US Veterans.

Effects of Exercise and Diet on Body Composition and Physical Function in Older Hispanics with Type 2 Diabetes.

Type 2 Diabetes mellitus (DM2) affects 9.3% of the U.S.

Impact of including the cause of missing records on genetic evaluations for growth in commercial pigs.

It is of interest to evaluate crossbred pigs for hot carcass weight (HCW) and birth weight (BW); however, obtaining a HCW record is dependent on livability (LIV) and retained tag (RT). The purpose of this study is to analyze how HCW evaluations are affected when herd removal and missing identification are included in the model and examine if accounting for the reasons for missing traits improves the accuracy of predicting breeding values. Pedigree information was available for 1,965,077 purebred and crossbred animals.

Patients with lesions to the intraparietal cortex show greater proprioceptive realignment after prism adaptation: Evidence from open-loop pointing and manual straight ahead.

Reaching toward a target viewed through laterally refracting prisms results in adaptation of both visual and (limb) proprioceptive spatial representations. Common ways to measure adaptation after-effect are to ask a person to point straight ahead with their eyes closed ("manual straight ahead", MSA), or to a seen target using their unseen hand ("open-loop pointing", OLP). MSA measures changes in proprioception only, whereas OLP measures the combined visual and proprioceptive shift.

Determining the stability of accuracy of genomic estimated breeding values in future generations in commercial pig populations.

Genomic information has a limited dimensionality (number of independent chromosome segments [Me]) related to the effective population size. Under the additive model, the persistence of genomic accuracies over generations should be high when the nongenomic information (pedigree and phenotypes) is equivalent to Me animals with high accuracy. The objective of this study was to evaluate the decay in accuracy over time and to compare the magnitude of decay with varying quantities of data and with traits of low and moderate heritability.

An analysis of fear inhibition and fear extinction in a sample of veterans with obstructive sleep apnea (OSA): Implications for co-morbidity with post-traumatic stress disorder (PTSD).

Obstructive sleep apnea (OSA) is a respiratory condition characterized by interrupted sleep due to repeated, temporary collapse of the soft tissue of the upper airway that can lead to a cascade of physiological and psychological adverse health outcomes. The most common therapeutic interventions for OSA patients include the application of continuous positive airway pressure (CPAP) which acts to keep the airway open and, as such, provides less interrupted and more restorative sleep. Improved sleep has been linked to more efficacious treatments for psychiatric conditions most notably those that include cognitive-behavioral elements, new learning, and memory consolidation.

Distress and Resilience in Resettled Refugees of War: Implications for Screening.

There is little work published about predictors of specific trajectory types of distress in refugees of war during early resettlement in a host country. Data about distress (Refugee Health Screener-15 (RHS-15)) and possible predictors of distress were collected at the domestic medical examination (T1) within 90 days of arrival and the civil surgeon examination (T2) 11-16 months after T1 for refugee groups from three countries (COU). Descriptive, correlative, analyses of variance, and regression techniques were used to determine trajectory type and their predictors.

Cortical volume abnormalities in posttraumatic stress disorder: an ENIGMA-psychiatric genomics consortium PTSD workgroup mega-analysis.

Studies of posttraumatic stress disorder (PTSD) report volume abnormalities in multiple regions of the cerebral cortex. However, findings for many regions, particularly regions outside commonly studied emotion-related prefrontal, insular, and limbic regions, are inconsistent and tentative. Also, few studies address the possibility that PTSD abnormalities may be confounded by comorbid depression.

Validation of single-step GBLUP genomic predictions from threshold models using the linear regression method: An application in chicken mortality.

The objective of this study was to determine whether the linear regression (LR) method could be used to validate genomic threshold models. Statistics for the LR method were computed from estimated breeding values (EBVs) using the whole and truncated data sets with variances from the reference and validation populations. The method was tested using simulated and real chicken data sets.

Prazosin for treatment of post-traumatic stress disorder: a systematic review and meta-analysis.

Background: Prazosin has been an accepted treatment for patients with post-traumatic stress disorder (PTSD) who experience sleep disturbances, including nightmares. Results of a recent large randomized control trial did not find benefit of prazosin vs placebo in improving such outcomes. A meta-analysis that includes this most recent trial was conducted to examine the pooled effect of prazosin vs placebo on sleep disturbances and overall PTSD symptoms in patients with PTSD.

Mental Health Effects of Stress over the Life Span of Refugees.

Information about the relative impact of stressful events across the lifespan on the mental health of refugees is needed. Cross-sectional data from a community sample of 135 Kurdish and 117 Vietnamese refugees were fit to a path model about the effects of non-war stress, war-related stress, and post-migration stress on mental health. Kurdish and Vietnamese data were generally consistent with the model.

A Double-Blind, Placebo-Controlled Randomized Trial of Vilazodone in the Treatment of Posttraumatic Stress Disorder and Comorbid Depression.

Objective: To determine the efficacy, safety, and tolerability of vilazodone in the treatment of posttraumatic stress disorder (PTSD) with comorbid mild-to-moderate depression.

Methods: A 12-week randomized, double-blind, placebo-controlled trial was conducted in adult outpatients who met DSM-IV criteria for PTSD with comorbid depression between February 2013 and September 2015. Participants were randomly assigned to receive vilazodone 40 mg/d or placebo, and outcome measures were obtained at scheduled visits.

Sleep-Disordered Breathing Impact on Efficacy of Prolonged Exposure Therapy for Posttraumatic Stress Disorder.

There is growing evidence that sleep disturbances may impede the utility of existing therapeutic interventions for people with posttraumatic stress disorder (PTSD). This retrospective medical record review examined the hypothesis that sleep disturbance affects the outcome of prolonged exposure (PE) therapy for PTSD. We identified 18 combat veterans with PTSD who had completed PE therapy.
