Comparison of two plates and screw osteosynthesis configurations in a rat model of critical sized femoral defects to reduce implant related failures.

This study aimed to compare the failure rates of two different sizes of plates and screws to stabilize critical-sized (7 mm) femoral defects in male Sprague‒Dawley rats (aged 10 weeks). Femoral defects were stabilized with either a 4-hole plate (length 29 mm, thickness 1 mm, 10 rats, Group 1) and 4 cortical screws (diameter 2 mm) or with a 6-hole plate (length 30 mm, thickness 0.6 mm, 9 rats, Group 2) and 4 cortical screws (diameter 1.

Is there a correlation between the scaphoid's morphology, the development of arthritis and the long-term functional outcomes in patients treated for nonunion with a bone graft?

Introduction: The main complication following scaphoid fracture is nonunion, which requires a surgical intervention to prevent the development of Scaphoid Nonunion Advanced Collapse (SNAC) wrist arthritis. In some cases, the bone eventually heals in malunion. There is a lack of published data on the clinical and radiological consequences of these malunions.

Alcohol-based antisepsis without the use of chlorhexidine for arthroscopy in horses.

Alcohol-based antisepsis has shown experimentally to be as effective as 4 % chlorhexidine gluconate (CHG) at reducing bacterial counts (colony forming units; CFU) on equine skin. Our objectives were to determine the immediate and post-surgical reduction in CFU/mL on equine skin prepared with CHG-based or 70 % isopropyl alcohol (IPA)-based (without CHG) protocols in a clinical setting with arthroscopic surgery. Our hypotheses were that the logCFU/mL reduction would not significantly differ between protocols immediately after preparation or at the end of surgery.

Alcoholic beverage consumption and female breast cancer risk: A systematic review and meta-analysis of prospective cohort studies.

Alcohol consumption is an established cause of female breast cancer. This systematic review examines in detail the association between alcohol and female breast cancer overall and among the described subgroups, using all of the evidence to date. A systematic review of PubMed and Embase was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines.

A Scoping Review of Factors Affecting COVID-19 Vaccination Uptake and Deployment in Global Healthcare Systems.

: COVID-19 vaccines were rapidly developed and deployed on a large scale during a global crisis. A range of deployment strategies were used globally to maximize vaccine uptake. In this scoping review, we identify and analyze the main healthcare system and policy factors that guided and influenced COVID-19 vaccination deployment and uptake globally.
