Lung Transplant Success in COVID-19 Patients Requiring V-V ECMO: One-Year Follow-Up.

BACKGROUND Acute respiratory distress syndrome (ARDS) due to coronavirus 2019 (COVID-19) can result in severe disease requiring mechanical ventilatory support. A subset of these patients, however, demonstrate refractory hypoxemia/hypercarbia requiring veno-venous extracorporeal membrane oxygenation (V-V ECMO) as adjunctive therapy. The primary goal of V-V ECMO is a "bridge" to recovery of native lung function; however, patients may progress to irreversible pulmonary damage requiring lung transplantation.

Particulate air pollution at the time of oocyte retrieval is independently associated with reduced odds of live birth in subsequent frozen embryo transfers.

Study Question: Does exposure to particulate matter (PM) air pollution prior to oocyte retrieval or subsequent frozen embryo transfer (FET) affect the odds of live birth?

Summary Answer: Live birth rates are lower when particulate matter (PM2.5 and PM10) levels are higher prior to oocyte retrieval, regardless of the conditions at the time of embryo transfer.

What Is Known Already: Exposure to air pollution is associated with adverse reproductive outcomes, including reduced fecundity and ovarian reserve, and an increased risk of infertility and pregnancy loss.

Clinical outcomes validate the RAND/UCLA appropriateness criteria algorithm for anatomical total shoulder arthroplasty for streamlining the clinical decision-making process.

Aims: A recent study used the RAND Corporation at University of California, Los Angeles (RAND/UCLA) method to develop anatomical total shoulder arthroplasty (aTSA) appropriateness criteria. The purpose of our study was to determine how patient-reported outcome measures (PROMs) vary based on appropriateness.

Methods: Clinical data from a multicentre database identified patients who underwent primary aTSA from November 2004 to January 2023.

Does matching glenosphere size to patient height improve outcomes following reverse total shoulder arthroplasty?

Introduction: Optimal biomechanics in reverse total shoulder arthroplasty (rTSA) are still a topic of debate. Although larger glenospheres have been linked with a theoretical improvement in the range of movement, results from clinical studies are mixed. We hypothesised that matching glenosphere diameter to patient height would result in greater improvements in post-operative range of motion (ROM) and patient-reported outcomes (PROMs).

Anatomic Total Shoulder Arthroplasty Revised to Reverse Total Shoulder Arthroplasty: Clinical and Radiographic Outcomes Compared to Primary Reverse Total Shoulder Arthroplasty.

Introduction: Reverse total shoulder arthroplasty (rTSA) has become the procedure of choice for a failed aTSA. Little data exists regarding outcomes; the few studies published to date have small numbers, short follow-up, and most do not have a control group or use first generation implants. The purpose of this study is to compare the clinical and radiographic outcomes of failed aTSA revised to rTSA to primary rTSA.
