Background: Anterior shoulder dislocations are the most common type of joint dislocation with the majority treated with closed reduction. Reduction methods can be grouped into their principle mode of action: traction-countertraction, leverage and scapular manipulation. The best method has yet to be identified and our aim was to find the most effective, safe and least painful method of closed reduction for acute anterior shoulder dislocations.
Methods: A search of the online databases of CENTRAL, MEDLINE and Embase was performed to identify randomised control trials (RCTs) comparing closed reduction methods for anterior shoulder dislocations. A systematic review and meta-analysis were performed following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines.
Results: Twelve eligible RCTs were included with a total of 1055 patients. Our meta-analysis showed traction-countertraction methods are marginally less painful than leverage methods by 0.86 points on the VAS scale but leverage methods are quicker by 20 s. Amongst traction-countertraction methods, the Spaso technique was the least painful and quickest, albeit with no difference in overall success rate. A meta-analysis was not possible for comparisons involving scapular manipulation due to the paucity of studies, but within two studies, scapular manipulation was significantly less painful than both leverage and traction-countertraction methods by 1.5 and 2.3 points (VAS), respectively.
Conclusion: Traction-countertraction methods are less painful but slower than leverage methods with no difference in complication rates. However, there was no difference in overall reduction success rate between any of the groups.
Level Of Evidence: I.

3,4-methylenedioxymethamphetamine (MDMA; commonly referred to as "ecstasy" or "molly") is a substituted amphetamine drug that is used recreationally for its acute psychoactive effects, including euphoria and increased energy, as well as prosocial effects such as increased empathy and feelings of closeness with others. Acute adverse effects can include hyperthermia, dehydration, bruxism, and diaphoresis. Post-intoxication phenomena may include insomnia, anhedonia, anxiety, depression, and memory impairment, which can persist for days following drug cessation.

Objective: This study aimed to report the clinical, radiographic, and computed tomography results of supracutaneous locking plate (SLP) application in radial-ulnar and tibial fractures.
Study Design: In this clinical prospective study, cats and dogs with nonarticular radial, ulnar, and tibial fractures were managed with SLP. Surgical records, fracture healing, complications, and lameness were reviewed during scheduled rechecks.

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.

Heterogeneous catalysts have emerged as a potential key for closing the carbon cycle by converting carbon dioxide (CO) into value-added chemicals. In this work, we report a highly active and stable ceria (CeO)-based electronically tuned trimetallic catalyst for CO to CO conversion. A unique distribution of electron density between the defective ceria support and the trimetallic nanoparticles (of Ni, Cu, Zn) was established by creating the strong metal support interaction (SMSI) between them.

Background: Prevention of depression, stress, and anxiety is a serious concern of the World Health Organization and has been a research topic over the last decades. There is a close association found between children's mental health problems and parental stress, valid for biological and foster families. Evidence suggests that parents with children with disabilities are more stressed, depressed, or anxious than parents who do not have such children.
