Risk-adjusted quality measures are used to evaluate healthcare providers with respect to national norms while controlling for factors beyond their control. Existing healthcare provider profiling approaches typically assume that the between-provider variation in these measures is entirely due to meaningful differences in quality of care. However, in practice, much of the between-provider variation will be due to trivial fluctuations in healthcare quality, or unobservable confounding risk factors.

- * Key factors affecting nitrogen excretion included dry matter intake, nitrogen intake, dietary composition, and animal growth metrics; models were evaluated using statistical measures like root mean square error (RMSE) and concordance correlation coefficient (CCC).
- * While fecal N excretion models showed better accuracy than those for urinary excretion, different predictors led to varying performances, with nitrogen intake generally performing better for urine, indicating the complexity of predicting N excretion based on diet and management.
This study aimed to evaluate the effects of supplementation with non-protein nitrogen (NPN) or ruminal undegradable protein (RUP) on intake, digestibility, and amino acid (AA) use efficiency of Nellore cattle grazing during the dry season. Eight Nellore steers (12 ± 2 months old) were used in quadruplicate Latin squares (2 × 2). The animals were placed on cv.

Study Design: Retrospective observational study.
Setting & Participants: 625,040 US maintenance dialysis patients with >90 kidney failure days in 2019.
Tourniquet-related nerve injuries (TRNIs) are a rare but feared complication of operative tourniquet use. While the literature contains multiple discussions regarding tourniquet use as well as reported cases of its complications, there does not exist a consensus guideline for a safe tourniquet pressure, application time, or management of TRNI. This paper conducts a comprehensive review of the available literature for cases of TRNI with a specific focus on analyzing the management of cases of TRNI and their functional recovery.
