Cambridge risk score, new hyperglycemia, and complications in surgical patients without diabetes.

Aims: Our study examined the association between the Cambridge Risk Score (CRS), new hyperglycemia (NH), and complications in patients undergoing elective surgery.

Methods: In this retrospective cross-sectional study, adult surgical patients, without diabetes, with NH (blood glucose ≥140 mg/dL) were identified, and the CRS was calculated. We used univariate regression models to evaluate the relationship between CRS and NH with 30-day readmission, length of stay (LOS), and complications.

Glacial vicariance and secondary contact shape demographic histories in a freshwater mussel species complex.

Characterizing the mechanisms influencing the distribution of genetic variation in aquatic species can be difficult due to the dynamic nature of hydrological landscapes. In North America's Central Highlands, a complex history of glacial dynamics, long-term isolation, and secondary contact have shaped genetic variation in aquatic species. Although the effects of glacial history have been demonstrated in many taxa, responses are often lineage- or species-specific and driven by organismal ecology.

Anatomical determinants of upper airway collapsibility in obstructive sleep apnea: A systematic review and meta-analysis.

Upper airway (UA) collapsibility is one of the key factors that determine the severity of obstructive sleep apnea (OSA). Interventions for OSA are aimed at reducing UA collapsibility, but selecting the optimal alternative intervention for patients who fail CPAP is challenging because currently no validated method predicts how anatomical changes affect UA collapsibility. The gold standard objective measure of UA collapsibility is the pharyngeal critical pressure (P).

Potent, multi-target serine protease inhibition achieved by a simplified β-sheet motif.

Engagement of an extended β-sheet is a common substrate/inhibitor interaction at the active site of serine proteases and is an important feature of Laskowski mechanism inhibitors that present a substrate-like loop to a target protease. This loop is cleaved but subsequently relegated forming a stable inhibitor/protease complex. Laskowski inhibitors are ubiquitous in nature and are used extensively in serine protease inhibitor design.
