Postabortion contraceptive use among women in Nepal: results from a longitudinal cohort study.

Introduction: Although the Government of Nepal has developed strategies to integrate contraceptive services with abortion care to better meet the contraceptive needs of women, data indicate that significant gaps in services remain. This paper assessed post-abortion contraceptive use, trends over 36 -months, and factors influencing usage.

Methods: Data from this paper came from an ongoing cohort study of 1831 women who sought an abortion from one of the sampled 22 government-approved health facilities across Nepal.

Clinical and cost-effectiveness of first contact physiotherapy for musculoskeletal disorders in primary care: the FRONTIER, mixed method realist evaluation.

Background: First-contact physiotherapists assess and diagnose patients with musculoskeletal disorders, determining the best course of management without prior general practitioner consultation.

Objectives: The primary aim was to determine the clinical and cost-effectiveness of first-contact physiotherapists compared with general practitioner-led models of care.

Design: Mixed-method realist evaluation of effectiveness and costs, comprising three main phases: A United Kingdom-wide survey of first contact physiotherapists.

High resistance barrier and prophylactic protection in preclinical models of SARS-CoV-2 with two siRNA combination.

RNA interference is a natural antiviral mechanism that could be harnessed to combat SARS-CoV-2 infection by targeting and destroying the viral RNA. We identified potent lipophilic small interfering RNA (siRNA) conjugates targeting highly conserved regions of SARS-CoV-2 outside of the spike-encoding region capable of achieving ≥3-log viral reduction. Serial passaging studies demonstrated that a two-siRNA combination prevented development of resistance compared to a single siRNA approach.

Pharmacokinetics of pradofloxacin, florfenicol, and tulathromycin and response to treatment of steers experimentally infected with Mannheimia hemolytica.

Background: Bovine respiratory disease (BRD) is an economically important disease in the beef industry, and a major driver of therapeutic antibiotic use. Pharmacokinetic data of these drugs is relatively limited in diseased animals.

Hypothesis/objective: To determine the concentrations of pradofloxacin, florfenicol, and tulathromycin in the airways, plasma, and interstitial fluid (ISF) of steers with a clinically relevant model of bacterial respiratory disease.

Repeated fuel treatments fall short of fire-adapted regeneration objectives in a Sierra Nevada mixed conifer forest, USA.

Fire exclusion over the last two centuries has driven a significant fire deficit in the forests of western North America, leading to widespread changes in the composition and structure of these historically fire-adapted ecosystems. Fuel treatments have been increasingly applied over the last few decades to mitigate fire hazard, yet it is unclear whether these fuel-focused treatments restore the fire-adapted conditions and species that will allow forests to persist into the future. A vital prerequisite of restoring fire-adaptedness is ongoing establishment of fire-tolerant tree species, and both the type and reoccurrence of fuel treatments are likely to strongly influence stand trajectories.

The stroke meta-metric, Defect-Free Care, was maintained year-over-year within the Florida stroke registry during the COVID-19 pandemic.

Background: Resource allocation for stroke care was impacted worldwide by the Coronavirus 2019 (COVID19) pandemic. Regionally, worsened stroke outcomes varied, however comparative year-over-year in-hospital performance metrics from the pandemic are unreported. Therefore, within the large Florida Stroke Registry (FSR), we assessed the pandemic's effects upon the American Heart Association (AHA) Get With The Guidelines (GWTG) ischemic stroke metrics and the meta-metric, Defect-Free Care (DFC).

Safer and targeted use of antipsychotics in youth: an embedded, pragmatic randomized trial.

Background: Antipsychotic medications (AP) are inappropriately prescribed to young people. The goal of this pragmatic trial was to test a four-component approach to improved targeting of antipsychotic prescribing to people aged ≥3 and <18 years.

Methods: Clinicians in four health systems were cluster randomized by the number of previous AP orders and service line - specialty mental health and all others.

The Pharmacokinetics of Subcutaneous Eprinomectin in Plasma and Milk in Dry Dairy Cattle.

Parasitic infections in dairy cattle reduce herd immunity, milk production, and conception rates. This leads to higher production costs, compromised animal welfare, and increased interest in extralabel drug use. The extralabel use of anthelmintics poses food safety risks for consumers since appropriate withdrawal intervals in milk have yet to be established.

Novel drug sampling technique: portal vein catheterization in steers.

Objective: To determine the feasibility of catheterizing the portal vein to obtain serial portal vein blood samples in steers. We hypothesized that the portal vein catheterization would be a successful continuous sampling technique with minimal adverse effects in steers.

Methods: 2 groups of steers were used: a pilot group (n = 2) and experimental group (n = 6).

Cohort profile: the ADAPT study, a prospective study of pregnancy preferences, pregnancy, and health and well-being in the southwestern USA.

Purpose: Significant methodological shortcomings limit the validity of prior research on pregnancy decision-making and the effects of 'unintended' pregnancies on people's health and well-being. The Attitudes and Decisions After Pregnancy Testing (ADAPT) study investigates the consequences for individuals unable to attain their pregnancy and childbearing preferences using an innovative nested prospective cohort design and novel conceptualisation and measurement of pregnancy preferences.

Participants: This paper describes the characteristics of the ADAPT Study Cohort, comprised of 2015 individuals aged 15-34 years, assigned female at birth, recruited between 2019 and 2022 from 23 health facilities in the southwestern USA.

Exploring the impacts of fescue toxicosis on the pulmonary arterial pressure of angus cows.

Vasoconstriction of peripheral blood vessels is one of the hallmark symptoms of fescue toxicosis in cattle. Thus, it was hypothesized that exposure to ergot alkaloids would increase the pulmonary arterial pressure (PAP). The objectives of this study were to examine the relationship between PAP and different physiological parameters of cows grazing either endophyte-infected (EI) or novel-endophyte (EN) fescue, then evaluate changes in PAP and other physiological measurements in cows exposed to EI pastures and deemed as susceptible or tolerant based on animal performance.

Quantifying trade-offs between therapeutic efficacy and resistance dissemination for enrofloxacin dose regimens in cattle.

The use of antimicrobial drugs in food-producing animals contributes to the selection pressure on pathogenic and commensal bacteria to become resistant. This study aims to evaluate the existence of trade-offs between treatment effectiveness, cost, and the dynamics of resistance in gut commensal bacteria. We developed a within-host ordinary differential equation model to track the dynamics of antimicrobial drug concentrations and bacterial populations in the site of infection (lung) and the gut.

Indirect detector for ultra-high-speed X-ray micro-imaging with increased sensitivity to near-ultraviolet scintillator emission.

Ultra-high-speed synchrotron-based hard X-ray (i.e. above 10 keV) imaging is gaining a growing interest in a number of scientific domains for tracking non-repeatable dynamic phenomena at spatio-temporal microscales.

Validation of a reference interval for symmetric dimethylarginine in healthy goats and its comparison to values in goats with obstructive urolithiasis.

Background: Symmetric dimethylarginine (SDMA), a sensitive biomarker for detecting renal injury, has not been characterized in goats. Obstructive urolithiasis (OU) is the most common urinary tract disease in male small ruminants.

Hypothesis/objective: Establish an SDMA reference interval (RI) in healthy adult goats and describe SDMA concentrations in goats with OU.

Continuous sampling of healthy and mastitic quarters of lactating cattle by ultrafiltration after intramammary ceftiofur hydrochloride administration.

Background: Pharmacological activity of intramammary drugs depends on adequate drug concentrations within the cistern, but sampling is often limited. Insight into the active drug concentration within the mammary cistern may assist in determining effective and appropriate therapeutic decisions for cows being treated for mastitis.

Objective: Evaluate the disposition of ceftiofur hydrochloride administered intramammary in diseased and nondiseased quarters.

Heterotopic Splenic Tissue Mimicking Metastases on Magnetic Resonance Imaging.

Background: Heterotopic splenic tissue can occur following splenectomy and is typically asymptomatic, often discovered incidentally during imaging for other conditions. This benign condition may mimic malignant processes, posing diagnostic challenges especially in patients with a history of cancer or concurrent malignancy.

Case Description: We report the case of a 60-year-old male with a history of well-controlled hypertension and a splenectomy following a traumatic injury at age 7.

'We need more support and doctors that understand the process of tapering …': A content analysis of free-text responses to a questionnaire on discontinuing long-term benzodiazepine receptor agonist use.

Background: Many individuals worldwide continue to take benzodiazepine receptor agonists (BZRAs) long term (≥3 months). The aim of this study was to conduct a content analysis of the views and experiences of discontinuing long-term BZRA use as documented in the free-text responses of respondents to an online questionnaire examining mediators of behaviour change relating to the discontinuation of long-term BZRA use.

Design: The questionnaire was disseminated via online BZRA support groups to community-based adults with either current or previous experience of long-term BZRA use.

Self-avoidance dominates the selection of hippocampal replay.

Spontaneous neural activity sequences are generated by the brain in the absence of external input , yet how they are produced remains unknown. During immobility, hippocampal replay sequences depict spatial paths related to the animal's past experience or predicted future . By recording from large ensembles of hippocampal place cells in combination with optogenetic manipulation of cortical input in freely behaving rats, we show here that the selection of hippocampal replay is governed by a novel self-avoidance principle.

Exploring the cobia (Rachycentron canadum) genome: unveiling putative male heterogametic regions and identification of sex-specific markers.

Background: Cobia (Rachycentron canadum) is the only member of the Rachycentridae family and exhibits considerable sexual dimorphism in growth rate. Sex determination in teleosts has been a long-standing basic biological question, and the molecular mechanisms of sex determination/differentiation in cobia are completely unknown.

Results: Here, we reported 2 high-quality, chromosome-level annotated male and female cobia genomes with assembly sizes of 586.

Discovery of Potent, Orally Bioavailable Sphingosine-1-Phosphate Transporter (Spns2) Inhibitors.

Targeting the S1P pathway has resulted in the development of S1P1 receptor modulators for the treatment of multiple sclerosis and ulcerative colitis. We hypothesize that targeting an upstream node of the S1P pathway may provide an improved adverse event profile. In this report, we performed a structure-activity relationship study focusing on the benzoxazole scaffold in , which lead to the discovery of () as a potent inhibitor of S1P release from HeLa cells (IC: 51 ± 3 nM).

Management Considerations for Cervical Corpectomy: Updated Indications and Future Directions.

Together, lower back and neck pain are among the leading causes of acquired disability worldwide and have experienced a marked increase over the past 25 years. Paralleled with the increasing aging population and the rise in chronic disease, this trend is only predicted to contribute to the growing global burden. In the context of cervical neck pain, this symptom is most often a manifestation of cervical degenerative disc disease (DDD).
