7 days of L-citrulline supplementation does not improve running performance in the heat whilst in a hypohydrated state.

Purpose: 7 days L-citrulline supplementation has been reported to improve blood pressure, O kinetics, gastrointestinal (GI) perfusion and endurance cycling performance through increasing arterial blood flow. In situations where blood volume is compromised (e.g.

A Warm Environment Reduces Exogenous Glucose Oxidation and Endurance Performance during Cycling with Facing Airflow.

Unlabelled: Exercise in warm environments increases thermal/cardiovascular strain and decreases gastrointestinal (GI) integrity and endurance performance. However, laboratory-based studies have provided little to/no facing airflow, potentially exacerbating these effects, particularly for cycling, where convective cooling may be a major contributor to thermal balance.

Purpose: This study investigated the effect of cycling in a warm vs temperate environment with sufficient facing airflow on exogenous glucose use, performance, and GI responses.

Use of 1 mm Cerclage Cables in Surgical Treatment of Periprosthetic Femur Fractures.

Introduction: 1 mm cerclage cables have been introduced that can be placed under plates and hold reduction of periprosthetic femur fractures (PPFFx) around total hip arthroplasty (THA). Their utilization remains controversial due to the risk of nonunion secondary to periosteal stripping associated for their application. We compared surgical outcomes in patients with THA PPFFx treated with open reduction internal fixation (ORIF) and cables vs patients with PPFFx treated with ORIF without cables.

Does Body Mass Index Affect the Success of Two-Stage Management of Periprosthetic Joint Infection?

Background: Obesity is associated with increased infection risk after primary total joint arthroplasty. In this retrospective cohort analysis, we sought to assess the association between body mass index (BMI) and infection recurrence after two-stage revision total joint arthroplasty for periprosthetic joint infection (PJI).

Methods: Patients were grouped by BMI (< 30, 30 to 40, and ≥ 40) as non-obese, obese, and morbidly obese, and assessed for associations and timing of PJI reinfection as well as readmissions and complications.

Simultaneous Periprosthetic Joint Infection and Infective Endocarditis: Prevalence, Risk Factors, and Clinical Presentation.

Background: Infective endocarditis (IE) and periprosthetic joint infections (PJI) occur due to hematogenous bacterial spread, theoretically increasing the risk for concurrent infections. There is a scarcity of literature investigating this specific association. We aimed to assess the prevalence, comorbidities, and clinical presentation of patients who have simultaneous PJI and IE.
