Characterizing and understanding the photovoltage in n-Si/Au light-addressable electrochemical sensors.

Here, we characterize the photovoltage of n-Si/Au light-addressable electrodes (LAEs) over a range of solution potentials from -1 to +1 V. We find that the n-Si/Au photoelectrodes show photovoltages consistent with a semiconductor/liquid junction in contrast to a buried junction, which opposes our previous understanding of how photovoltage originates in these sensors.

Hip Fracture Post-operative Mortality and Polypharmacy: A New Risk Predictor?

Introduction Hip fractures include intra- and extracapsular fractures with hip hemiarthroplasty, intramedullary (IM nailing), dynamic hip screw (DHS) fixation and cannulated cancellous screws being the main treatment options. The Nottingham Hip Fracture Score (NHFS) is used to predict the risk of 30-day mortality with some studies investigating its use for one-year mortality. This study aims to investigate the impact of polypharmacy on post-operative hip fracture mortality and the correlation with NHFS predicted mortality.

Quantification and severity grading of femoral vessel compression by adverse reactions to metal debris in metal-on-metal total hip arthroplasty.

Introduction: Metal-on-metal (MoM) total hip arthroplasty (THA) may cause adverse reactions to metal debris (ARMD). ARMD causing femoral vessel compression with serious complications has been described in case reports, but the rate of compression by ARMD is not known. This study aims to investigate the rate, and quantify the severity, of femoral vessel compression in MoM hips with ARMD lesions.

Depression and Metabolic Syndrome: A Narrative Review.

We reviewed the literature to investigate the relationship between depression and metabolic syndrome. Major depressive disorder is characterized by a low mood or a loss of interest for longer than two weeks. Metabolic syndrome describes multiple metabolic risk factors including obesity, insulin resistance, dyslipidemia, and hypertension.

Bilateral Simultaneous Asymmetrical Anterior Shoulder Dislocation With a Fracture.

In this case report, we present the case of a 19-year-old male who presented to the emergency department with bilateral shoulder pain and significantly decreased range of motion. His X-rays showed a bilateral dislocation of the glenohumeral joints, along with a proximal humeral fracture. Shoulder dislocations were manipulated, while the proximal humeral fracture was conservatively managed.
