Comparative efficacy of operative versus conservative treatment for Rockwood type III acromioclavicular joint dislocation: a systematic review and meta-analysis of randomized controlled trials.

Background: Optimal management of Rockwood type III acromioclavicular joint (ACJ) dislocation is still debated. Our aim is to conduct a meta-analysis of clinical studies evaluating the functional outcomes of operative versus conservative treatment for Rockwood type III ACJ dislocation.

Methods: We conducted a systematic search across PubMed, EMBASE, Web of Science, and the Cochrane Library, including only randomized controlled trials (RCTs) focusing exclusively on type III ACJ dislocation.

Modulating the Schottky barrier of MXenes/2D SiC contacts functional groups and biaxial strain: a first-principles study.

Two-dimensional (2D) graphene-like SiC has attracted intense interest recently due to its unique electrical and physical properties. In implementing 2D semiconductors in device applications, one of the main challenges so far has been the formation of a high-quality Schottky barrier owing to the strong Fermi level pinning (FLP) at the interface of traditional metal-2D semiconductor contacts. In this paper, the 2D MXenes TiCT (T = F, O, OH) are proposed to serve as electrodes for 2D SiC.

Predictive value of post-operative neutrophil/lymphocyte count ratio for surgical site infection in patients following posterior lumbar spinal surgery.

Objective: Surgical site infection (SSI) is a common complication in patients following posterior lumbar spinal surgery. Various laboratory data such as laboratory parameters derived neutrophil/lymphocyte count ratio (NLR), have been applied for the prediction of SSI, but more studies are necessary to evaluate the significance of these indicators. Here, our study aims to investigate the predictive value of total white blood cells (WBCs), count and percentages of neutrophils and leukocytes, NLR, and C-reactive protein (CRP) for surgical site infection (SSI) in patients after posterior lumbar spinal surgery.

Cosputtered Calcium Manganese Oxide Electrodes for Water Oxidation.

Calcium manganese oxide films were prepared by cosputter deposition from Mn and CaMnO targets and evaluated for their suitability as catalysts for the oxygen evolution reaction (OER). Scanning electron microscopy (SEM) revealed a compact morphology for the as-deposited films and the formation of nanorodlike features on the surfaces after annealing at 600 °C. X-ray-photoelectron-spectroscopy analysis showed that the surface oxidation state is close to +III (as in MnO) for the as-deposited films and increases slightly to a mixture of III and IV after annealing occurs in dry air at 400-600 °C.
