Respiratory interventions including noninvasive ventilation, continuous positive airway pressure and high-flow nasal oxygen generated infectious aerosols may increase risk of airborne disease (SARS-CoV-2, influenza virus) transmission to healthcare workers. We developed and tested a prototype portable UV-C device to sterilize high flows of viral-contaminated air from a simulated patient source at airflow rates of up to 100 l/m. Our device consisted of a central quartz tube surrounded 6 high-output UV-C lamps, within a larger cylinder allowing recirculation past the UV-C lamps a second time before exiting the device.

Objective: To evaluate outcomes for workers' compensation (WC) versus commercially insured (CI) patients undergoing lumbar decompression (LD) at an ambulatory surgical center (ASC).

Methods: This is a retrospective cohort study utilizing propensity score matched groups. Patients undergoing elective LD at an ASC with two-year follow-up were identified and grouped based on insurance type (WC or CI).

About one in six couples experience fertility problems, and male infertility accounts for about half of these cases. Spermatogenesis originates from a small pool of spermatogonial stem cells (SSCs), which are of interest for the treatment of infertility but remain poorly characterised in humans. Using multiparametric spectral flow cytometric analysis with a 16-colours (16-C) panel of cell markers, we identify novel markers of SSCs and provide insights into unravelling and resolving the heterogeneity of the human spermatogonial cells.

Background: The insulin-like growth factor 1 receptor (IGF-1R) and the thyrotropin receptor (TSH-R) are expressed on orbital cells and thyrocytes. These receptors are targeted in autoimmune-induced thyroid eye disease (TED). Effective therapeutic treatment of TED inhibits activation of the IGF-1R/TSH-R complex.

Study Design: Retrospective review.

Objective: To validate using patient-reported outcome measurement information system-pain interference (PROMIS-PI) to assess outcomes in patients undergoing lumbar decompression surgery compared with well-established pain and disability measures.

Summary Of Background Data: PROMIS outcomes provide valuable information, but the PROMIS-PI measure has not been validated in lumbar decompression.
