Objectives: Septic arthritis after anterior cruciate ligament (ACL) reconstruction is a rare but potentially devastating complication. The imaging findings associated with such infections are not well-described or quantified. The purpose of this study was to describe and quantify the frequency of the characteristic MRI findings of infection following ACL reconstruction.

Appropriate patient reassurance is an essential feature of clinical practice. My recent experience as a patient, interpreted via my expertise as a health services researcher, led me to insights on ideal and suboptimal reassurance styles in the context of worrisome symptoms. Reassurance is complex: often poorly defined in the scientific literature, rarely rigorously studied, imperfectly understood, and requiring some adaptation to each patient situation.

Hydrophobic feedstocks such as waste cooking oil have recently been considered for microbial biotransformation due to their abundance, low cost, and unique advantage for lipid-derived fermentation products. Most fermentations with hydrophobic substrates are conducted at the tube or flask scale (less than 1 L total volume) or with the hydrophobic substrate comprising a small fraction of the media. Low substrate concentrations require additional feeding.

Owing to their rapid cooling rate and hence loss-limited propagation distance, cosmic-ray electrons and positrons (CRe) at very high energies probe local cosmic-ray accelerators and provide constraints on exotic production mechanisms such as annihilation of dark matter particles. We present a high-statistics measurement of the spectrum of CRe candidate events from 0.3 to 40 TeV with the High Energy Stereoscopic System, covering 2 orders of magnitude in energy and reaching a proton rejection power of better than 10^{4}.

Experiences in gender-sexuality alliances (GSAs) could predict youth's academic engagement through improved social-emotional wellbeing (indicated by school belonging, hope, and positive and negative affect). This study utilized three waves of data, each spaced 2-3 months apart, among 627 youth (87% LGBQ+, 45% trans/nonbinary, 48% youth of color) ages 11-22 (M = 15.13) in 51 GSAs in the United States in 2021-2022.
