Risk of Colonization with Multidrug-Resistant Gram-Negative Bacteria Among Travellers and Migrants: A Narrative Review.

Globalization in the 21st century has posed several challenges. In particular, the spread of multidrug-resistant bacterial strains, especially Gram-negative bacteria, which are prevalent in certain regions of the world, is one of the most critical issues. This raises concerns about the risks associated with the booming tourism industry and migratory flows.

Green Processing of : Antioxidant Concentration and Caffeine Reduction Using Encapsulation by Supercritical Antisolvent Process.

This study investigated the valorization of leaves by producing a low-caffeine, antioxidant-rich product through the supercritical antisolvent extraction (SAE) process. The objective was to concentrate the antioxidants while selectively reducing the caffeine. The SAE treatments were conducted using an ethanolic extract of guayusa leaves under varying pressure (80 bar-150 bar) and temperature (35-45 °C) conditions to improve the recovery of chlorogenic acid (CGA) and caffeine fractionation.

Encapsulation of Phenolic Compounds Extracted from Beet By-Products: Analysis of Physical and Chemical Properties.

Beet is a nutritious and health-promoting food with important bioactive compounds in its industrial by-products. The encapsulation of antioxidants from beet by-products has been proposed for valorization.

Validation of DOE Factorial/Taguchi/Surface Response Models of Mechanical Properties of Synthetic and Natural Fiber Reinforced Epoxy Matrix Hybrid Material.

A validation of the factorial, Taguchi and response surface methodology (RSM) statistical models is developed for the analysis of mechanical tests of hybrid materials, with an epoxy matrix reinforced with natural Chambira fiber and synthetic fibers of glass, carbon and Kevlar. These materials present variability in their properties, so for the validation of the models a research methodology with a quantitative approach based on the statistical process of the design of experiments (DOE) was adopted; for which the sampling is in relation to the design matrix using 90 treatments with three replicates for each of the study variables. The analysis of the models reveals that the greatest pressure is obtained by considering only the source elements that are significant; this is reflected in the increase in the coefficient of determination and in the predictive capacity.

The Effects of Long-Term High Fat and/or High Sugar Feeding on Sources of Postprandial Hepatic Glycogen and Triglyceride Synthesis in Mice.

Background: In MASLD (formerly called NAFLD) mouse models, oversupply of dietary fat and sugar is more lipogenic than either nutrient alone. Fatty acids suppress de novo lipogenesis (DNL) from sugars, while DNL inhibits fatty acid oxidation. How such factors interact to impact hepatic triglyceride levels are incompletely understood.

Vertical distributions of megafauna on inactive vent sulfide features correspond to their feeding modes.

The discovery of inactive hydrothermal vent sulfide features near 9°50'N on the East Pacific Rise provides an opportunity to investigate the distribution and feeding ecology of communities inhabiting this type of habitat. We quantify megafaunal distributions on two features, Lucky's Mound and Sentry Spire, to determine how taxonomic composition and feeding traits vary with vertical elevation. Fifty-one morphotypes, categorized by feeding mode, were identified from three levels of the features (spire, apron, and base) and the surrounding flat oceanic rise.

The contribution of Paulo Freire's thought to Popular Health Surveillance.

Paulo Freire considered Popular Education (PE) as an emancipatory process, through debate and critical action, as a dimension of human existence. This text aims to conduct a narrative literature review on the articulations of Paulo Freire's ideas with Popular Health Surveillance (PHS) actions based on his contributions to Education and Health. The text presents how the contributions of Paulo Freire and Popular Health Education inspired the construction of Popular Health Surveillance, which seeks to promote the transformation of local reality in the face of rights violations and advocate for life.

Design: A prospective, randomized, double-blinded, placebo-controlled, crossover trial of two clinically recommended vaccines (influenza and pneumococcal).

Methods: Persons with HIV on ART ( N  = 54) were enrolled in the clinical trial.

Effects of the COVID-19 Pandemic on Breastfeeding Initiation and Duration: A Retrospective Cohort Study.

Introduction And Objectives: Several studies support the health benefits of breastfeeding for both the mother and the newborn. However, a significant number of mothers discontinue breastfeeding within the first six months of childbirth, with several factors influencing breastfeeding adherence. The purpose of this study is to assess the impact of the COVID-19 pandemic on the prevention of mother-to-newborn infection transmission, breastfeeding patterns and duration, and the incidence of other infections during the first year of life.

Popular Health, Environmental and Occupational Surveillance: an integrative literature review.

The objective is to identify concepts, experiences, methods, and techniques in Popular Health, Environmental and Occupational Surveillance (VPSAT). This is an integrative review that used the descriptors: Community Participation, Public Health Surveillance, Environmental Health, and Occupational Health, using five databases: Virtual Health Library, EBSCOhost, Embase, Scopus and Web of Science. The review selected 15 studies, based on the inclusion criteria: surveillance experiences with community protagonism; and exclusion criteria: research without primary data and developed only by the health service.

Popular health surveillance practices in Brazil: scoping review.

This study aims to identify the Popular Health Surveillance practices in Brazil, described in the scientific literature. A scoping review was carried out in the LILACS, MEDLINE, MEDCARIB, PAHO-IRIS, WHOLIS, and Scopus databases from the CAPES Periodical Portal in May 2022. Studies that clearly addressed community/population protagonism in a health surveillance experience were included in the review, with a total of 6 studies.

ARCA: the interactive database for arbovirus reported cases in the Americas.

Background: Accurate case report data are essential to understand arbovirus dynamics, including spread and evolution of arboviruses such as Zika, dengue and chikungunya viruses. Giving the multi-country nature of arbovirus epidemics in the Americas, these data are not often accessible or are reported at different time scales (weekly, monthly) from different sources.

Results: We developed a publicly available and user-friendly database for arboviral case data in the Americas: ARCA.

Expression of recombinant dengue virus type 1 non-structural protein 1 in mammalian cells and preliminary assessment of its suitability to detect human IgG antibodies elicited by viral infection.

In recent years dengue has become a rapidly growing public health problem worldwide, however, the availability of accurate and affordable diagnostic immunoassays is limited, partly due to the difficulty of producing large quantities of purified antigen. Non-structural protein 1 (NS1) has shown to be a good candidate for inclusion in diagnostic assays and for serosurveys, particularly in endemic countries as a prerequisite for vaccination. In this work the NS1 antigen derived from dengue virus type-1 (DENV1) was expressed in HEK293-T cells and purified by affinity chromatography.
