Randomized Clinical Trial Comparing Mixed Liposomal Bupivacaine versus Continuous Catheter for Interscalene Block during Shoulder Arthroplasty: A Comparison of Analgesia, Patient Experience, and Cost.

Background: Continuous interscalene catheters extend analgesia beyond 24 hours but are resource-intensive, while the efficacy of liposomal bupivacaine for single-injection interscalene blocks remains uncertain. The purpose of this investigation was to examine the analgesic efficacy, quality of recovery, and treatment costs between interscalene nerve block using either an indwelling catheter or single shot block using liposomal bupivacaine, in patients undergoing shoulder arthroplasty.

Methods: In this single-center, parallel, unblinded, randomized clinical trial, 83 patients undergoing primary shoulder arthroplasty were assigned to either a continuous interscalene catheter group (n=44) or a single-injection liposomal bupivacaine interscalene block group (n=39).

Complications after reverse shoulder arthroplasty for proximal humerus nonunion.

Background: Proximal humerus nonunion is a challenging complication of fractures that can be treated surgically with either open reduction internal fixation (ORIF) or reverse total shoulder arthroplasty (RTSA). The few studies published on this subject have shown high rates of complications and revision surgery when RTSA has been performed for proximal humerus nonunion. The purpose of this study was to determine the rates of complications and revision of this procedure at our institution, as well as to identify any variables that may impact risks of complications and reoperations.

Operative treatment of acromial and scapular spine fracture nonunions complicating reverse total shoulder arthroplasty.

Background: Fractures of the acromion and spine can have a major impact on the outcome of reverse shoulder arthroplasty (RSA) with respect to pain, motion, and function. Reports on internal fixation for these fractures are isolated to small series or case reports with variable outcomes. The purpose of this study was to report on the outcome of open reduction and internal fixation (ORIF) of acromion or spine fractures encountered before or after RSA and describes our evolution of fixation techniques.

A plain language summary of the PHAROS study: the combination of encorafenib and binimetinib for people with BRAF V600E-mutant metastatic non-small-cell lung cancer.

What Is This Summary About?: This is a summary of the results of a study called PHAROS. This study looked at combination treatment with encorafenib (BRAFTOVI) and binimetinib (MEKTOVI). This combination of medicines was studied in people with metastatic non-small-cell lung cancer (NSCLC).

The First Brazilian Cardiovascular Registry of Atrial Fibrillation: Primary Results of the RECALL Study.

Background: It is estimated that atrial fibrillation (AF) affects approximately 1.5 million people in Brazil; however, epidemiological data are limited. We sought to evaluate the characteristics, treatment patterns, and clinical outcomes in patients with AF in Brazil by creating the first nationwide prospective registry.
