Absorption cross section of gas phase isoprene in the infrared-visible range.

We have recorded the gas phase spectrum of isoprene at room temperature from the mid-infrared range and into the visible range (600 cm to 17050 cm). Absorption spectra were obtained by Fourier transform infrared, conventional dispersion ultraviolet-visible-near-infrared and cavity ring-down spectroscopy to cover the entire range with a resolution comparable to that of the instruments on the James Webb Space Telescope. We have assigned the CH-stretching fundamental and overtone bands corresponding to the Δv=1-6 transitions based on anharmonic vibrational calculations using normal mode and local mode models, for the lower- and higher-energy regions, respectively.

The Role of Ombuds in Graduate Medical Education: Fostering Wellness and Psychological Safety.

The authors propose an educational innovation in graduate medical education, the creation of an Education Ombudsperson. Although this role has been implemented for faculty and students within the medical field, it has not been described in residency programs. The Ombudsperson for house staff is distinct from institutional or programmatic leadership.

Association of patellofemoral osteoarthritis on patient-reported outcomes after medial unicompartmental knee arthroplasty: a retrospective cohort study.

Background And Purpose:  In contemporary medial unicompartmental knee arthroplasty (mUKA), non-lateral patellofemoral osteoarthritis (PFOA) is not considered a contraindication. However, we still lack knowledge on the association of PFOA severity on patient reported outcome measures (PROMs) after mUKA. We aimed to examine the association between PFOA severity and PROM-score changes after mUKA.

Rebound in Fecal Testing, Colonoscopy Utilization, and Colorectal Neoplasia Detection During the COVID-19 Pandemic.

Objectives: The COVID-19 pandemic reduced colorectal cancer (CRC) screening, but the rebound in testing and outcomes following the pandemic has not been widely reported. We evaluated CRC test utilization and colorectal neoplasia detection among screening eligible patients in a large health system in 2020 and 2021, compared to 2019 (pre-pandemic).

Methods: Using a retrospective cohort study design, fecal immunochemical test (FIT) and colonoscopy utilization, FIT positivity, and neoplasia detection were evaluated annually in 2019-2021 among Kaiser Permanente Northern California patients aged 50-75 years overall and by sex, age, race and ethnicity, and spoken language preference.

Continuous Characterization of Insoluble Particles in Ice Cores Using the Single-Particle Extinction and Scattering Method.

This study presents the integration of the single-particle extinction and scattering (SPES) method in a continuous flow analysis (CFA) setup. Continuous measurements with the instrument allow for the characterization of water-insoluble particles in ice cores at high resolution with a minimized risk of contamination. The SPES method can be used to investigate particles smaller than 1 μm, which previously could not be detected by instruments typically used in CFA.
