The objective of this study was to compare surgical and conservative treatment at a minimum follow-up of 1 year in terms of the complications, functional outcomes and clinical results. HYPOTHESES: There is no difference in the complications, clinical results and functional outcomes between the two treatment groups. There is no difference in the occurrence of complications or the clinical results due to the immobilization or rehabilitation protocols...

BACKGROUND: Cutibacterium acnes ( C acnes ) is a commensal skin bacterium, primarily found in sebaceous glands and hair follicles, with a high prevalence in the shoulder region. It is the most common pathogenic organism in prosthetic joint infections after shoulder arthroplasty. Because of its low virulence, its diagnosis remains difficult. PURPOSE: To evaluate the relative effects of topical preparations in reducing C acnes in shoulder surgery. STUDY DESIGN: Meta-analysis; Level of evidence, 1...

BACKGROUND: Glenoid reconstruction with a bone block for anterior glenoid bone loss (GBL) has shown excellent outcomes. However, fixation techniques that require metal implants are associated with metal-related complications and bone graft resorption. HYPOTHESIS: Arthroscopic glenoid reconstruction using a tricortical iliac crest bone graft (ICBG) and metal-free suture tape cerclage fixation can safely and effectively restore the glenoid surface area in patients with recurrent anterior shoulder instability and anterior GBL...

OBJECTIVES: Acute myeloid leukaemia (AML) and high-risk myelodysplastic syndromes (MDS) are often treated with intensive chemotherapy followed by allogeneic haematopoietic stem cell transplantation (allo-HSCT). The pretransplant treatment results in a general deterioration of the patient's health and quality of life. Furthermore, allo-HSCT can be responsible for significant toxicity with risks of graft-versus-host disease (GvHD). Developing strategies to prevent physical deconditioning, undernutrition and psychological distress could help maintain a satisfactory general state of health before transplantation and thus limit these deleterious effects...

BACKGROUND/OBJECTIVE: Given the persistence of COVID-19 under various facets and mutations, there is an urgent need to understand the debate on a safe return to play for professional athletes (young and adults) recovering from the infection. This work offers a scoping and comprehensive review on the topic during the first two years of the pandemic event by providing an identification of main clusters of research, relevant gaps and significant insights for future investigation. METHODS: The literature is selected using the search engines of: PubMed® , SCIENCEDIRECT, and SCOPUS...

PURPOSE: Knee dislocation is a rare but severe injury of the lower extremities. The aim of this study was to report on the epidemiology, diagnostics and treatment of such injuries and to identify negative predictors of clinical outcomes. METHODS: This retrospective analysis included all knee dislocations treated at a Level I Trauma Centre in Germany between 2009 and 2021. Medical records were categorised, collected and analysed in a standardised manner. A follow-up visit 1 year after the injury focused on limitations in knee mobility...

The pivotal role of the immune system in physical activity is well-established. While interactions are complex, they tend to constitute discrete immune responses. Moderate intensity exercise causes leukocytosis with a mild anti-inflammatory cytokine profile and immunoenhancement. Above a threshold of intensity, lactate-mediated IL-6 release causes a proinflammatory followed by a depressed inflammatory state, which stimulates immune adaptation and longer term cardiometabolic enhancement. Exercise-related immune responses are modulated by sex, age and immune-nutrition...

BACKGROUND: Studies in collegiate athletes have demonstrated a prevalence of cardiac involvement between 0.5 and 3 % after SARS-CoV-2 infection. When post-COVID cardiac involvement occurs in athletes, the ideal return to play timeline and many possible long-term sequela or complications are unknown. CASE SUMMARY: A 20 yo female collegiate athlete tested positive for SARS-CoV-2 and underwent routine cardiac screening prior to her return to play (RTP). Evaluation demonstrated an elevated high-sensitivity troponin-I and an ECG showed some mild T wave changes...
