Background: The World Health Organization (WHO) declared COVID-19 a pandemic on March 11, 2020. Patients who tested positive for COVID-19 experienced a higher overall rate of post-surgical complications and hospital mortality.
Objective: To compare the asociation of post-surgical complications presented in post-surgical hip patients with and without history of COVID-19 infection.
Material And Methods: Prospective cohort study. The inclusion criteria were: post-hip surgery adults with and without a history of COVID-19 infection who attended their post-surgical follow-up consultation. The association of post-surgical complications in both groups was studied. The association of complications was analyzed with the chi-squared statistical test, and the effect size with Cramer's V test.
Results: The association of complications and a history of COVID-19 infection was moderate, with a chi-squared of 2.55, V Cramer of 0.23. The most frequent complication was aseptic loosening of prosthetic components. The pre-surgical diagnosis and its association with both groups had a chi-squared of 10.07, and a V Cramer of 0.45, at the expense of hip fracture.
Conclusions: A history of COVID-19 infection may be associated with the presence of post-surgical complications. Aseptic loosening of prosthetic components was the most frequent complication in both groups of patients, and hip fracture was the main pre-surgical diagnosis.

Orthopedic, maxillofacial, and complex dentoalveolar bone grafting procedures that require donor-site bone harvesting can be associated with post-surgical complications. There has been widespread adoption of exogenously sourced particulate bone graft materials (BGM) for bone regenerative procedures; however, the particulate nature of these materials may lead to compromised healing outcomes, mainly attributed to structural collapse of the BGM, prolonged tissue healing. In this study, a fully synthetic thermoresponsive hydrogel-based universal carrier matrix (TX) that forms flowable and shapable putties with different BGMs while spatially preserving the particles in a 3D scaffold at the implantation site is introduced.

Abdominal adhesions are a frequent complication after abdominal surgery, which can cause significant pain and burden to patients. Despite various treatment options, including surgical intervention and pharmacotherapy, these often fail to consistently and effectively prevent postoperative abdominal adhesions. Janus hydrogel is famous for its asymmetric characteristics, which shows great prospects in the prevention and treatment of abdominal adhesion.

Objective: To assess the effectiveness and safety profiles of rivaroxaban compared to low molecular weight heparin (LMWH) in managing lower extremity deep vein thrombosis (DVT) subsequent to thoracoscopic lung cancer surgery.
Methods: Sixty patients diagnosed with lower extremity deep vein thrombosis (DVT) following thoracoscopic lung cancer surgery were randomly assigned to two groups: the experimental group comprising 30 patients treated with rivaroxaban, and the control group consisting of 30 patients treated with low molecular weight heparin (LMWH). The fundamental clinical characteristics of patients in both groups were documented, encompassing parameters, along with pre- and post-surgical lower limb vascular ultrasound findings.

Objective: To investigate the relationship between the grip strength (GS) and stress urinary incontinence (SUI) after endoscopic enucleation of the prostate (EEP).
Methods: We retrospectively collected 87 patients who underwent EEP at our center from January to December 2023. The associations between GS and post-surgical SUI at immediate, 1, 4, 12 and 24 weeks were analyzed.

The study assessed the effectiveness and safety of nerve block combined with low-dose general anaesthesia in elderly hip arthroplasty patients, conducted by a meta-analysis of RCTs. Six trials involving 403 patients were identified from databases such as Cochrane, MEDLINE, and PubMed. The results demonstrated a statistically significant difference in pain scores at postoperative 12hours (95% CI, -2.
