Background: Due to its indolent nature, nontuberculous mycobacteria (NTM) are increasing in global prevalence as a cause of pulmonary infections and are difficult to treat with traditional antibiotics. Here, we study the repurposing of clofazimine (CFZ) to treat NTM through expanded access in a single health system. Our main objectives are to describe the feasibility of accessing and analyzing expanded access data and to generate hypotheses regarding CFZ use in NTM treatment.

Musculoskeletal (MSK) complaints are prevalent in law enforcement officers (LEOs), but research that examines their risk factors is limited. This study aimed to identify the self-reported MSK complaint prevalence and perceived causes in LEOs. The Nordic musculoskeletal questionnaire was used to identify the 12-month and 7-day prevalence of MSK 'trouble' (ache, pain, discomfort) for nine body sites.

This study aimed to assess (i) COVID-19 transmission prior to and following spectator events and (ii) methodological approaches to capturing event-related transmission during the spectator return. Local authority population transmission rates were used to identify higher transmission areas, which were excluded from participant attendance following registration. Using observational online and SMS questionnaires, self-reported COVID-19 diagnoses (positive tests) and racing-related NHS Test and Trace contacts within 14 days of spectating were reported for two British Horseracing events and three Point to Point (PTP) grassroots races.

Article Synopsis
  • - The study investigates injury incidence and characteristics among professional male and female jockeys in both flat and jump racing in Great Britain, focusing on data from 245 jockeys licensed between 2007 and 2017.
  • - Results show that most injuries occurred during races, with a significant percentage being soft tissue injuries, and jump racing having a much higher fall and injury incidence compared to flat racing.
  • - Notably, female flat jockeys experienced more falls than their male counterparts, while flat jockeys were more likely to sustain injuries when they fell, indicating important differences in risks based on racing type and gender.

Background: Physical activity is an important component of healthy lifestyles, with a central role in morbidity prevention. However, sporting and physical activity also involve an inherent injury risk. Some sports and activities have a higher injury risk, and may involve more severe injuries.

Article Synopsis
  • Osteoarthritis significantly contributes to disability, particularly among retired NFL players, highlighting the need to identify risk factors and potential interventions to prevent severe cases.
  • A study of 2432 retired NFL athletes found that 11.4% underwent joint replacements, with knee replacements being more common than hip replacements, and a high prevalence of previous severe knee injuries.
  • Key risk factors for knee replacements included older age, increased weight, and a history of knee injuries, with the incidence of replacement rising with the number of reported injuries.

To examine the prevalence of chronic disease and mental health problems in retired professional, male jockeys compared to an age-matched reference population. A cross-sectional study comparing data from a cohort of retired professional jockeys with an age-matched general population sample. Male participants (age range: 50-89 years old) were used to compare health outcomes of self-reported physician-diagnosed conditions: heart disease, stroke, diabetes, hypertension, osteoporosis, osteoarthritis, depression and anxiety between study populations.

Objectives: This study aimed to determine the prevalence of hand and wrist osteoarthritis in former elite cricket and rugby union players, by sport and playing position, and to define the prevalence of severe hand injury, and its association with hand osteoarthritis.

Design: Cross-sectional.

Methods: Data from cross-sectional studies of former elite male cricket and rugby players were used to determine the prevalence of hand pain, physician-diagnosed osteoarthritis, and previous severe injury.

Introduction: Relatively little is known about the long-term health of former elite rugby players, or former sportspeople more generally. As well as the potential benefits of being former elite sportspersons, there may be potential health risks from exposures occurring during an individual's playing career, as well as following retirement. Each contact sport has vastly different playing dynamics, therefore exposing its players to different types of potential traumas.

In the general population, physical activity is associated with improved health outcomes. However, long-term sports participation may be associated with adverse outcomes, particularly at the elite level. The aims of this study were to assess morbidity and health-related quality of life (HrQoL) amongst former rugby players, compared to an age-standardised general population sample.

A 19-year-old man was sent to the emergency department following a pitch-side assessment for suspected concussion, unexplained upper abdominal tenderness and vomiting, following a high-impact tackle during a rugby match. A Focussed Assessment with Sonography for Trauma (FAST) scan performed in the emergency department suggested intra-abdominal free fluid, and subsequent head and abdominal CT imaging showed no intracranial lesion but confirmed a significant haemoperitoneum due to large splenic tear and bleeding. An emergency splenectomy was performed, which confirmed the rupture of an enlarged spleen with blood loss of almost 2 L into the peritoneal cavity.
