Association between prognostic nutritional index and all-cause mortality and cardiovascular disease mortality in American adults with non-alcoholic fatty liver disease.

Background: The current research was to investigate the relationship between prognostic nutritional index (PNI) and mortality, with a focus on all-cause and cardiovascular disease (CVD) mortality, for those with non-alcoholic fatty liver disease (NAFLD).

Methods: Data from 20,142 patients who participated in the National Health and Nutrition Examination Survey (NHANES), which was carried out between 2005 and 2014, were included in this research. To examine the relationship between PNI and both all-cause and cardiovascular mortality, we employed weighted Cox regression models with multiple variables.

[Body Function Changes and Prevention Strategies in High-Altitude Environment].

In high-altitude regions, the unique challenges posed by the low-oxygen environment exert significant stress on the physiological functions of the human body. Currently, there is an urgent need to develop a deeper understanding of the pathogenesis, prevention and treatment strategies, as well as effective interventions, of altitude sickness. In this paper, we explored the self-regulatory mechanisms of the human body in such extreme environments, elaborating on the adaptive mechanisms at the molecular level and the process of acclimatization to high altitudes.

Balancing the efforts of chart review and gains in PRS prediction accuracy: An empirical study.

Objective: Phenotypic misclassification in genetic association analyses can impact the accuracy of PRS-based prediction models. The bias reduction method proposed by Tong et al. (2019) has demonstrated its efficacy in reducing the effects of bias on the estimation of association parameters between genotype and phenotype while minimizing variance by employing chart reviews on a subset of the data for validating phenotypes, however its improvement of subsequent PRS prediction accuracy remains unclear.

Chain reactions of temperature-induced egg white protein amorphous aggregates: Formation, structure and material composition of thermal gels.
