Detection of porcine reproductive and respiratory syndrome virus type 2 in air emissions from grow-finish barns.

Background: Diagnosis of porcine reproductive and respiratory syndrome virus (PRRSV) infections can be accomplished using various sample types and testing methods.  The objective of this study was to evaluate the feasibility of using air emission samples to detect the onset of PRRSV type 2 infections in growing pigs.

Methods: Air emissions and oral fluid samples were collected from three grow-finish barns, stocked with PRRSV-negative pigs every 2 weeks for 14-20 weeks.

PRRSV-2 variant classification: a dynamic nomenclature for enhanced monitoring and surveillance.

Existing genetic classification systems for porcine reproductive and respiratory syndrome virus type 2 (PRRSV-2), such as restriction fragment length polymorphisms and sub-lineages, are unreliable indicators of close genetic relatedness or lack sufficient resolution for epidemiological monitoring routinely conducted by veterinarians. Here, we outline a fine-scale classification system for PRRSV-2 genetic variants in the United States. Based on >25,000 U.

Stress Management Program for Scanxiety in People With Advanced Lung Cancer: Intervention Adaptation and Stakeholder Feedback.

Background: Although scanxiety is common and impactful for people with advanced lung cancer, few interventions address this psychosocial concern.

Aims: To create a stress management program for scanxiety.

Methods: We conducted a structured intervention adaptation process guided by the ADAPT-ITT framework.

Predicting Elevated Postvoid Residual Urine Volume Following OnabotulinumtoxinA Treatment for Overactive Bladder: A Pilot Study.

Objectives: To evaluate possible predictors of elevated postvoid residual volume (PVR) following onabotulinumtoxinA administration in patients with idiopathic overactive bladder (OAB), a condition that may include urinary urgency, frequency, and nocturia, without any identifiable cause or underlying neurological or metabolic condition.

Methods: Adults who had been treated with 100-200 U onabotulinumtoxinA for OAB and had previous failure of other OAB treatments were identified by retrospective review of medical chart data from three urology clinics in the United States treating patients with a variety of urological conditions. A total of 211 patients were allocated to cohorts based on posttreatment PVR < 200 mL (n = 173) and ≥ 200 mL (n = 38).

Sex Differences in Melanoma Survival-a GEM study.

Sex differences in melanoma are prominent, with females having a significant survival advantage. However, it is unclear why we see this survival advantage. Here we investigate the relationship between sex, clinicopathologic variables, and melanoma specific survival in 1,753 single primary melanomas from patients in the GEM study.
