Male osteoporosis is primarily caused by a decrease in testicular testosterone production. Male osteoporosis remains a disease with insufficient diagnosis and treatment, and its consequences are severe, especially in older patients. The gut microbiota plays a crucial role in its occurrence and development.

Inadequate vascularization significantly hampers wound recovery by limiting nutrient delivery. To address this challenge, we extracted membrane vesicles from (LMVs) and identified their angiogenic potential via transcriptomic analysis. We further developed a composite hydrogel system (Gel-LMVs) by anchoring LMVs within carboxylated chitosan and cross-linking it with oxidized hyaluronic acid through a Schiff base reaction.

Background: Rotator cuff repair (RCR) is a frequently performed outpatient orthopaedic surgery, with substantial financial implications for health-care systems. Time-driven activity-based costing (TDABC) is a method for nuanced cost analysis and is a valuable tool for strategic health-care decision-making. The aim of this study was to apply the TDABC methodology to RCR procedures to identify specific avenues to optimize cost-efficiency within the health-care system in 2 critical areas: (1) the reduction of variability in the episode duration, and (2) the standardization of suture anchor acquisition costs.

Aligned electrospinning membranes (Align) have demonstrated the potential to enhance wound healing by establishing a regenerative microenvironment surrounding the wound; However, the precise mechanism underlying its facilitation of healing remains unclear. To elucidate aligned electrospun fiber membrane's role in accelerating wound healing and improving its quality, we conducted a comprehensive analysis. Firstly, in vivo experiments confirmed that Align promotes wound healing.

Platelet-derived extracellular vesicles (PEVs) are rich in growth factors and have significant potential for facilitating tissue repair and regeneration. Therefore, we conducted this meta-analysis to assess the efficacy of PEVs in treating diabetic wounds. To assess the efficacy and safety of PEVs in treating diabetic wounds, we conducted a systematic review of several databases and performed a meta-analysis using a random effects model.
