[Clinical-epidemiological profile of patients hospitalized with COVID-19 in Coronel Suárez, Argentina].

To contribute to the study of the disease, data were recorded from all hospitalized patients in the Clinical Medicine room of Hospital Municipal Dr. Raúl Caccavo, Coronel Suárez, Buenos Aires province, diagnosed with COVID-19 in the first year of the pandemia (March 2020 to March 2021), the only health institution where patients were hospitalized in our city. A descriptive and retrospective transversal cut study was carried out with 178 patients (average age: 61 years old, range: 9 months -96 years), 90% of them hospitalized for a respiratory cause.

Zebu cattle fed dry distiller's grain or cottonseed meal had greater nitrogen utilization efficiency than non-supplemented animals.

This study evaluated intake, apparent digestibility, ruminal parameters, nitrogen balance, and microbial protein synthesis in grazing beef cattle fed a mineral mix or combination of two coproducts (cottonseed meal and dried distiller's grains (DDG)) during the wet season. Urochloa brizantha cv. Marandu pastures were managed under continuous stocking to maintain a fixed grazing height of 25 cm using put-and-take methodology.

Organic additives used in beef cattle feedlot: Effects on metabolic parameters and animal performance.

Organic additives are recently being used in animal diets owing to their ability to control metabolic issues and result in better animal performance. Specifically, the organic additive Fator P presents an additional advantage that is to cause a lesser greenhouse gas emission. This study evaluated whether Fator P intake changes ruminal parameters or animal performance of beef cattle.

Prediction of beef color using time-domain nuclear magnetic resonance (TD-NMR) relaxometry data and multivariate analyses.

Time-domain nuclear magnetic resonance and chemometrics were used to predict color parameters, such as lightness (L*), redness (a*), and yellowness (b*) of beef (Longissimus dorsi muscle) samples. Analyzing the relaxation decays with multivariate models performed with partial least-squares regression, color quality parameters were predicted. The partial least-squares models showed low errors independent of the sample size, indicating the potentiality of the method.
