Public resources on the Brazilian Food and Nutrition Security agenda from 2000 to 2022.

To analyze the time trend of federal public resources invested in the Brazilian Food and Nutrition Security agenda from 2000-2022. A time series study was carried out with data collected from a publicly accessible system on the Federal Government's planning and budget. We analyzed the budget actions and their resources indicated by the Budget Allocation and the Settled Amount.

Authentic Nursing Leadership and Safety Climate Across Hospital Settings During the COVID-19 Pandemic: A Cross-Sectional Study.

Aim: To analyse the relationship between authentic nursing leadership and safety climates across hospital settings during the COVID-19 pandemic.

Background: Authentic nursing leadership shapes the safety climate by fostering positive perceptions of workplace policies, processes, procedures and practices that influence how safety is prioritised and addressed within an organisation.

Design: A cross-sectional study.

The Primacy of Adipose Tissue Gene Expression and Plasma Lipidome in Cardiometabolic Disease in Persons With HIV.

Background: Persons with HIV (PWH) on contemporary antiretroviral therapy (ART) are at elevated risk for developing age-related cardiometabolic diseases. We hypothesized that integrative analysis of cross-tissue, multimodal data from PWH could provide insight into molecular programming that defines cardiometabolic phenotypes in this high-risk group.

Methods: We enrolled 93 PWH without diabetes who were virologically suppressed on contemporary ART and obtained measures of insulin resistance, glucose intolerance, and adiposity.

A prognostic molecular signature of hepatic steatosis is spatially heterogeneous and dynamic in human liver.

Hepatic steatosis is a central phenotype in multi-system metabolic dysfunction and is increasing in parallel with the obesity pandemic. We use a translational approach integrating clinical phenotyping and outcomes, circulating proteomics, and tissue transcriptomics to identify dynamic, functional biomarkers of hepatic steatosis. Using multi-modality imaging and broad proteomic profiling, we identify proteins implicated in the progression of hepatic steatosis that are largely encoded by genes enriched at the transcriptional level in the human liver.

Detecting the Major Degradation Products of Phosphorothioate Oligonucleotides by Chemical Derivatization and Weak Anion Exchange Chromatography.

Novel polar cysteine analogues have been synthesized for the derivatization of oligonucleotide depurination impurities that may be formed under acidic conditions. Depurination impurities belong to a group that includes deamination and phosphate diester impurities, which are similar in chemical structure to each other and the parent oligonucleotide, and thus coelute by most chromatographic separation methods. The polar cysteine analogues react with depurination impurities and enable their complete separation from the parent oligonucleotide by weak anion exchange (WAX) chromatography.
