Article Synopsis
- Young children have high nutritional needs, especially for lysine, and improving their diets with enriched foods is essential due to their small portion sizes.
- An enzymatic lysine-α-oxidase (LOx) sensor was developed to measure lysine content in flour mixtures, showing significant increases in lysine concentration with added lablab purpureus.
- The biosensor successfully quantified lysine levels in various flours, proving to be an effective tool for assessing and enhancing the nutritional quality of these food products.
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.

The authors use the knowledge-to-action framework to describe the implementation strategy for Proyecto Escala de Valoracion de Alerta Temprana (EVAT), a multicenter quality-improvement collaborative, to scale-up PEWS in pediatric oncology centers in Latin America.
Methods: Proyecto EVAT mentored participating centers through an adaptable implementation strategy to: (1) monitor clinical deterioration in children with cancer, (2) contextually adapt PEWS, (3) assess barriers to using PEWS, (4) pilot and implement PEWS, (5) monitor the use of PEWS, (6) evaluate outcomes, and (7) sustain PEWS.
Article Synopsis
- - This study analyzed maternal deaths linked to COVID-19 in eight Latin American countries from March 2020 to November 2021, using data from a regional perinatal information system.
- - Out of 447 identified deaths, most women were infected before giving birth, with the majority showing symptoms like dyspnea, fever, and cough, and experiencing significant organ dysfunction; many deaths occurred shortly after delivery, often linked to preterm or low-birth-weight infants.
- - The findings highlight the need for improved access to intensive care for pregnant women in Latin America, emphasizing the importance of raising awareness about the severity of COVID-19 during pregnancy and enhancing referral systems to prevent delays in care.
Context: Wide variation in state and county health spending prior to 2020 enables tests of whether historically better state and locally funded counties achieved faster control over COVID-19 in the first 6 months of the pandemic in the Unites States prior to federal supplemental funding.
Objective: We used time-to-event and generalized linear models to examine the association between pre-pandemic state-level public health spending, county-level non-hospital health spending, and effective COVID-19 control at the county level. We include 2,775 counties that reported 10 or more COVID-19 cases between January 22, 2020, and July 19, 2020, in the analysis.
