The incidence and treatment of symptomatic acromioclavicular joint osteoarthritis following total shoulder arthroplasty.

Background: Acromioclavicular joint (ACJ) Osteoarthritis (OA) is very common in the general population. Despite this, there is little mention of concomitant glenohumeral and ACJ arthropathy in the literature, and no documented incidence of symptomatic ACJ OA post total shoulder arthroplasty (TSA). We present the incidence and timescale of the problem, and the response to treatments.

Routine platelet transfusion in patients with traumatic intracranial hemorrhage taking antiplatelet medication: Is it warranted?

Background: After a traumatic intracranial hemorrhage (tICH), patients often receive a platelet transfusion to reverse the effects of antiplatelet medication and to reduce neurologic complications. As platelet transfusions have their own risks, this study evaluated their effects on tICH progression, need for operations and mortality.

Methods: In this retrospective study, we identified patients admitted to a level 1 trauma centre with a tICH from 2011 to 2015 who were taking acetylsalicylic acid (ASA) or clopidogrel, or both.

Building trust in American hospital-community development projects: a scoping review.

Although it has become increasingly common for hospitals to engage in development projects aimed at improving the social determinants of health in surrounding communities, scholarly literature examining the establishment of trust between hospitals and communities is sparse. Because of an extensive and complex history of abuse suffered by marginalized populations at the hands of medical institutions, trust building is critical to the pursuit of equitable health outcomes in these communities. A scoping review was conducted to assess the current base of knowledge for building trust between hospital systems and community members.

Regulating the Regulators: Mechanisms of Substrate Selection of the O-GlcNAc Cycling Enzymes OGT and OGA.

Thousands of nuclear and cytosolic proteins are modified with a single β-N-acetylglucosamine on serine and threonine residues in mammals, a modification termed O-GlcNAc. This modification is essential for normal development and plays important roles in virtually all intracellular processes. Additionally, O-GlcNAc is involved in many disease states, including cancer, diabetes, and X-linked intellectual disability.

Generation of an Interactome for the Tetratricopeptide Repeat Domain of O-GlcNAc Transferase Indicates a Role for the Enzyme in Intellectual Disability.

The O-GlcNAc transferase (OGT) modifies nuclear and cytoplasmic proteins with β--acetyl-glucosamine (O-GlcNAc). With thousands of O-GlcNAc-modified proteins but only one OGT encoded in the mammalian genome, a prevailing question is how OGT selects its substrates. Prior work has indicated that the tetratricopeptide repeat (TPR) domain of OGT is involved in substrate selection.

Differences in Endothelin B Receptor Isoforms Expression and Function in Breast Cancer Cells.

The endothelins and their receptors are best known for their regulation of the vascular system. Their widespread expression in epithelial cells and their overexpression in some tumors has prompted investigation into their ability to regulate cancer progression. In this study, we assessed the mRNA expression of the major endothelin B receptor gene (EDNRB) isoforms and found differences in both mRNA and protein expression in normal breast cells and breast cancer cell lines.

An intellectual disability syndrome with single-nucleotide variants in O-GlcNAc transferase.

Intellectual disability (ID) is a neurodevelopmental condition that affects ~1% of the world population. In total 5-10% of ID cases are due to variants in genes located on the X chromosome. Recently, variants in OGT have been shown to co-segregate with X-linked intellectual disability (XLID) in multiple families.

Alarmins in Frozen Shoulder: A Molecular Association Between Inflammation and Pain.

Background: The pathophysiological mechanisms behind proliferation of fibroblasts and deposition of dense collagen matrix in idiopathic frozen shoulder remain unclear. Alarmins (also known as danger signals) are endogenous molecules that are released into the extracellular milieu after infection or tissue injury and that signal cell and tissue damage.

Purpose: To investigate whether the presence of alarmins is higher in patients with idiopathic frozen shoulder than in control subjects.

The changing case-mix of hip fractures in Scotland - evidence from the Scottish Hip Fracture Audit.

Until discontinued in 2008, the Scottish Hip Fracture Audit collected and reported on data relating to the quality of care of hip fracture patients in Scotland. In 2013, the audit was recommenced under the umbrella of the MSK Audit group, which audits high volume orthopaedic pathways across Scotland. Our aim is to report on the changes in the demographics of hip fracture patients in Scotland between 2003 and 2013.

Development of real-time PCR assays for genotyping of Chlamydia trachomatis.

We have developed and validated a nested real-time PCR (NRT-PCR) for the genotyping of Chlamydia trachomatis and used it specifically for the typing of either eight genovars from D to K or three genovars of lymphogranuloma venereum (LGV). The 11 probes used in the NRT-PCR correctly identified the DNA from D to K and LGV reference strains and did not cross-react with the DNA from 26 strains representing the bacterial pathogens and commensals of the oropharynx, genital tract, and rectum. The NRT-PCR had a 95% probability of detection at four genome copies (confidence interval, three to six copies) of C.

Comparative performance of the Roche COBAS Amplicor assay and an in-house real-time PCR assay for diagnosis of Chlamydia trachomatis infection.

This study investigated the comparative performance of the Amplicor assay and an in-house semi-automated, multiplex real-time PCR for the diagnosis of genital chlamydial infection. Four different assays, the COBAS Amplicor CT test (Amplicor PCR), in-house real-time PCR (IHRT-PCR), in-house nested cryptic plasmid PCR and in-house nested major outer membrane protein PCR, were performed on genital swabs from 1000 consecutive patients attending a genitourinary medicine clinic. The samples were designated true positive if Chlamydia trachomatis DNA was detected by at least two of the four above-mentioned assays while a sample was defined as true negative if C.

Development and validation of a rotor-gene real-time PCR assay for detection, identification, and quantification of Chlamydia trachomatis in a single reaction.

A multitarget real-time PCR (MRT-PCR) for detection of Chlamydia trachomatis DNA was developed and validated. There were three targets for amplification in a single reaction: the cryptic plasmid (CP), the major outer membrane protein (MOMP) gene, and an internal control. The assay had the following characteristics: (i) detection and confirmation of the presence of C.
