Prevalence of abnormal liver biochemistry and its impact on COVID-19 patients' outcomes: a single-center Greek study.

Background: Abnormalities in aminotransferases are frequently observed in hospitalized COVID-19 patients, but their clinical impact is poorly characterized.

Methods: A total of 1046 patients hospitalized to the non-intensive care unit ward with documented COVID-19 were included retrospectively. Demographic, clinical and laboratory characteristics on admission and during hospital stay, including the presence of liver injury (LI), defined as aspartate aminotransferase (AST) >200 IU/L, were recorded.

Functional Outcomes of Bilateral Reverse Total Shoulder Arthroplasty: A Systematic Review.

 To answer the question whether bilateral reverse total shoulder arthroplasty (RTSA) is a safe and effective treatment which results in satisfactory clinical and functional outcomes with low complications rates. A second question to be answered was: what is the quality of the evidence of the already published studies which investigate the use of bilateral RTSA?  Two reviewers independently conducted a systematic search according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses using the MEDLINE/PubMed database and the Cochrane Database of Systematic Reviews. These databases were queried with the terms "reverse" AND "total" AND "shoulder" AND "arthroplasty" AND "clinical.

Non-rigid fixation of the glenoid bone block for patients with recurrent anterior instability and major glenoid bone loss: A systematic review.

Background: New types of glenoid bone block fixation, involving suture buttons, suture anchors or even implant-free impaction of the graft, have been recently introduced. In contrast to screws which allow for a rigid fixation of the bone block, these alternative procedures provide a non-rigid type of fixation.

Methods: Two reviewers independently conducted the search in a systematic way (according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) using the MEDLINE/PubMed database and the Cochrane Database of Systematic Reviews.

The clinical outcome of the 'Surgilig' technique for the reconstruction of acromioclavicular dislocations: A systematic review.

Purpose: To investigate whether the 'Surgilig' technique is safe and effective for the treatment of patients suffering from acromioclavicular joint (ACJ) dislocations graded as Rockwood's type III or higher.

Methods: A systematic review was conducted according to Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) guidelines.

Results: The failure rate of the "Surgilig" implant was very low (3.

All-Arthroscopic McLaughlin's Procedure in Patients with Reverse Hill-Sachs Lesion Caused by Locked Posterior Shoulder Dislocation.

 This study aims to investigate the clinical and functional outcomes of the all-arthroscopic McLaughlin procedure in a clinical series of patients suffering by neglected locked posterior shoulder dislocation.  A retrospective clinical study based on prospectively collected data was conducted in a single center regarding 10 patients with neglected locked posterior shoulder dislocation and concomitant reverse Hill-Sachs lesion, who were treated with the all-arthroscopic Mclaughlin procedure. The average humeral bone defect was 39 ± 7% according to the preoperative computed tomography evaluation.

Is subscapularis repair associated with better outcome compared to non-repair in reverse total shoulder arthroplasty? A systematic review of comparative trials.

We aimed to investigate whether combined reverse total shoulder arthroplasty (RTSA) and subscapularis repair leads to improved clinical and functional outcome in comparison with RTSA alone. Two reviewers independently conducted a systematic search according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) using the MEDLINE/PubMed database and the Cochrane Database of Systematic Reviews. These databases were queried with the terms "reverse" AND "shoulder" AND "arthroplasty" AND "with" AND "subscapularis" AND "repair".
