A cross-sectional survey of farmer reported prevalence and farm management practices associated with neonatal infectious arthritis ("joint ill") in lambs, on UK sheep farms.

Introduction: Neonatal infectious arthritis (NIA) is a bacterial disease of lambs in the first month of life. NIA is associated with poor animal welfare, economic losses, and prophylactic antibiotic use. Farmers report problems with NIA despite following current guidance on prevention.

Sex Differences in Tryptophan Metabolism via the Kynurenine Pathway in Acute Ischemic Stroke.

Purpose: Females are at increased lifetime risk of stroke and experience worse outcomes compared with males. Tryptophan metabolism through the kynurenine pathway, resulting in decreased tryptophan concentrations, is associated with poor outcomes (larger infarct volume, higher National Institutes of Health Stroke Scale [NIHSS] score, and increased early mortality). This metabolic pathway activity varies by sex in healthy adults.

State of the Art Review: Aortic Valve Repair in Infants and Children.

Background: Congenital aortic and truncal valve disease is challenging in infants and children given the lack of available prostheses in very small sizes and the limited durability of homograft aortic valve replacement.

Methods: A comprehensive literature search was performed using the PubMed database. Studies were included either if the report included patients less than 1 year of age or if the technique was tailored to accommodate for somatic growth.

Description of control measures, attitudes, and behaviours at a scientific conference with a confirmed COVID-19 case but no reported onward transmission, November 2021 England.

Background: COVID-19 (coronavirus disease 2019) outbreaks in workplace settings have been investigated to understand how transmission occurred. However, there is limited data looking at COVID-19 transmission in conference settings in England, particularly where an outbreak did not occur. The aim of this work was to investigate COVID-19 infection risk factors and control measures at a large conference, with a known case but no reported onward transmission to inform prevention of future outbreaks of respiratory infections in conferences and similar settings.

RBCs regulate platelet function and hemostasis under shear conditions through biophysical and biochemical means.

Red blood cells (RBCs) have been hypothesized to support hemostasis by facilitating platelet margination and releasing platelet-activating factors such as adenosine 5'-diphosphate (ADP). Significant knowledge gaps remain regarding how RBCs influence platelet function, especially in (patho)physiologically relevant hemodynamic conditions. Here, we present results showing how RBCs affect platelet function and hemostasis in conditions of anemia, thrombocytopenia, and pancytopenia and how the biochemical and biophysical properties of RBCs regulate platelet function at the blood and vessel wall interface and in the fluid phase under flow conditions.

Sex Differences in the Blood Metabolome During Acute Response to Ischemic Stroke.

Females suffer greater lifetime risk of stroke and greater morbidity and mortality from stroke compared with males. This study's objective was to identify differences in metabolomic profiling of females and males with stroke and which differences were associated with neurological outcome. Females and males with acute ischemic stroke enrolled in the Emergency Medicine Specimen Bank at a comprehensive stroke center provided whole blood samples upon arrival for mass spectrometry-based metabolomics.

A SARS-CoV-2 outbreak investigation at a storage and distribution centre in England: an assessment of worker- and workplace-related risk factors.

An outbreak of SARS-CoV-2 (1 March to 10 May 2021) with an attack rate of 26.5% among approximately 1150 workers at a storage and distribution centre in England prompted a multidisciplinary outbreak investigation (5 May to 6 August 2021), with the aim of better understanding worker- and workplace-related risk factors for viral transmission in the warehousing sector. Overall, environmental factors (e.

Nitrofurantoin resistance as an indicator for multidrug resistance: an assessment of urinary tract specimens in England, 2015-19.

Objectives: To determine whether MDR occurs more frequently in nitrofurantoin-resistant urinary isolates in England, compared with nitrofurantoin-susceptible isolates.

Methods: Using routine urine isolate antibiotic susceptibility laboratory surveillance data for England, 2015-19 inclusive, the percentage of MDR or XDR phenotype was estimated for nitrofurantoin-susceptible and nitrofurantoin-resistant laboratory-reported urinary tract samples by region, patient sex and age group.

Results: Resistance to nitrofurantoin among urinary samples decreased slightly year on year from 2.

Anticipated Versus Unanticipated Incomplete Mohs Micrographic Surgery for Keratinocyte Carcinomas: Impact on Treatment Delays and Final Margin Status.

Background: Mohs micrographic surgery may be discontinued with positive margins as an anticipated strategy for multidisciplinary care or as an unanticipated occurrence. Management of primary tumors has not been compared after anticipated versus unanticipated incomplete Mohs micrographic surgery (iMMS).

Objective: To compare rates and timing of adjuvant surgery after iMMS and final margin status when iMMS is anticipated versus unanticipated.

False-Positive Rates, Risk Factors, and Interpretations of the Vestibular/Ocular Motor Screening in Collegiate Athletes.

Context: Biological sex and history of motion sickness are known modifiers associated with a false-positive baseline Vestibular/Ocular Motor Screening (VOMS). However, other factors may be associated with a false-positive VOMS in collegiate athletes.

Objective: To identify contributing factors to false-positive VOMS assessments using population-specific criteria.

Recent Advances in the Field of Artificial Intelligence for Precision Medicine in Patients with a Diagnosis of Metastatic Cutaneous Melanoma.

Standard-of-care medical imaging techniques such as CT, MRI, and PET play a critical role in managing patients diagnosed with metastatic cutaneous melanoma. Advancements in artificial intelligence (AI) techniques, such as radiomics, machine learning, and deep learning, could revolutionize the use of medical imaging by enhancing individualized image-guided precision medicine approaches. In the present article, we will decipher how AI/radiomics could mine information from medical images, such as tumor volume, heterogeneity, and shape, to provide insights into cancer biology that can be leveraged by clinicians to improve patient care both in the clinic and in clinical trials.

A prospective cohort study examining the association of claw anatomy and sole temperature with the development of claw horn disruption lesions in dairy cattle.

Foot characteristics have been linked to the development of sole lesions (sole hemorrhage and sole ulcers) and white line lesions, also known as claw horn disruption lesions (CHDL). The objective of this study was to examine the association of claw anatomy and sole temperature with the development of CHDL. A cohort of 2,352 cows was prospectively enrolled from 4 UK farms and assessed at 3 time points: before calving (T1-precalving), immediately after calving (T2-calving), and in early lactation.

Provider Perceptions of Oxygenation Strategies for Critically Ill Trauma Patients With and Without Moderate-to-Severe Traumatic Brain Injury.

Background: Hypoxia and hyperoxia (pulse oximetry [SpO2] > 96%) are associated with increased mortality in critically ill patients. However, provider practices regarding oxygenation in traumatic brain injury (TBI) patients are unknown. This study assesses views on oxygenation of critically ill trauma patients with and without TBI and how this varies between Neurological ICU (NeuroICU) and Surgical-Trauma ICU (STICU) providers.

Appropriateness of acute-care antibiotic prescriptions for community-acquired infections and surgical antibiotic prophylaxis in England: analysis of 2016 national point prevalence survey data.

Background: Estimates of inappropriate prescribing can highlight key target areas for antimicrobial stewardship (AMS) and inform national targets.

Objectives: To (1) define and (2) produce estimates of inappropriate antibiotic prescribing levels within acute hospital trusts in England.

Methods: The 2016 national Healthcare-Associated Infections (HAI), Antimicrobial Use (AMU) and AMS point prevalence survey (PPS) was used to derive estimates of inappropriate prescribing, focusing on the four most reported community-acquired antibiotic indications (CAIs) in the PPS and surgical prophylaxis.

Sex differences in acute ischemic stroke presentation are a matter of infarct location.

Introduction: Recognition of stroke by Emergency Medical Services (EMS) is critical to initiate rapid emergency department treatment. Most prehospital stroke screening tools rely heavily on presentation with the classic symptoms of facial droop, speech changes, unilateral weakness. However, women may be less likely to present with classic symptoms and may also have different distributions of stroke by anatomical location.
