Large-scale commercial-grade volatile fatty acids production from sewage sludge and food waste: A holistic environmental assessment.

The valorization of sewage sludge and food waste to produce energy and fertilizers is a well-stablished strategy within the circular economy. Despite the success of numerous laboratory-scale experiments in converting waste into high-value products such as volatile fatty acids (VFAs), large-scale implementation remains limited due to various technical and environmental challenges. Here, we evaluate the environmental performance of a hypothetical large-scale VFAs biorefinery located in Galicia, Spain, which integrates fermentation and purification processes to obtain commercial-grade VFAs based on primary data from pilot plant operations.

Methodological guide and roadmap to assess the compliance of wastewater treatment plants with sustainability and circularity criteria.

Environmental certification has come up as a voluntary action to demonstrate a minimum quality level when it comes to the introduction of ecological-friendly principles in decision-making. However, most of the work done so far has focused on the food and agroforestry sectors and on the production and processing stages of the value chain rather than end-of life strategies. The present study aims to provide a roadmap that facilitates the evaluation of the performance wastewater facilities from sustainable and circularity perspectives.

Mesenchymal stem cell therapies evidence in the treatment of irradiated salivary glands: A scoping review.

Background: Radiotherapy is one of the main treatments for head and neck cancer; however, due to its non-selectivity the glandular tissue can be affected. This scoping review aimed to identify the evidence about mesenchymal stem cell therapies for irradiated salivary gland regeneration.

Material And Methods: Two independent reviewers performed a literature search in MEDLINE/PubMed, Scopus, and Web of Science.

Infant Passive Protection Against Coronavirus Through Exclusive Breastfeeding: A Cross-Sectional Study.

Background/objectives: This study aimed to determine the percentage and duration of neutralizing antibodies against the Omicron variant in human milk after vaccination against SARS-CoV-2, considering the three different vaccine technologies approved in Brazil.

Methods: A cross-sectional study was conducted with lactating women who received the complete vaccination cycle with available vaccines (AstraZeneca, Pfizer, CoronaVac, and Janssen). The participants resided in Rio de Janeiro, and samples were collected from April to October 2022.

Invasive infections by group A Streptococcus infections in Brazil: a pediatric case series.

Objective: Group A Streptococcus (GAS) are Gram-positive cocci that colonize the nasopharynx and/or skin and in rare cases may cause severe invasive infections. Although these infections decreased during the COVID-19 pandemic, some countries have observed an increased number of invasive GAS (iGAS) diseases in recent years. The objective of this study was to describe a series of iGAS diseases in a referral hospital for the treatment of pediatric infectious disease in Minas Gerais State, Brazil, between September 2022 and August 2023.
