This paper is an integrative review of the literature that sought to identify the factors that influence the adhesion and acceptance of school food among Brazilian and American students, and to show the main differences between the programs of these two countries. the following databases were consulted: Latin American and Caribbean Health Sciences (Lilacs); Pubmed; Scientific Electronic Library Online (Scielo); and Science Direct. Data were collected between July and August 2015, using the following key words in Portuguese and English: "adherence to school food" (adesão à alimentação escolar), "accepting of school feeding" (aceitação à alimentação escolar) and the "National School Lunch Program" ("Programa Nacional de Alimentação Escolar"). The search resulted in 7 Brazilian articles and 7 Americans articles published between 2004 and 2014, besides the current laws of each program, selected in the electronic sites of agencies responsible for administrating them. After descriptive and comparative analysis, the results revealed that adherence and acceptance are low in both programs, and they are influenced by socioeconomic factors, competitive foods present in the school environment and students' food preferences.

Assessment of temperature dynamics during methane oxidation in a pilot scale compost biofilter.
Bioresour Technol

Instituto de Ingeniería, Universidad Nacional Autónoma de México, Circuito Escolar, Ciudad Universitaria, C.P. 04510 Ciudad de México, México. Electronic address:
Biological methane oxidation can sustain high temperatures in organic matrices, such as landfill covers and compost biofilters. This study investigates the temperature dynamics, methane removal efficiency, and microbial community responses in a pilot scale compost biofilter under three methane concentrations (2, 4, and 8 % v v in air) with a 23-minute empty bed residence time. Complete methane removal was achieved at 2 %, with compost bed temperatures reaching 51 °C.

Background: The 'univentricular' heart encompasses a variety of congenital cardiac defects characterized by a single functional ventricle and an underdeveloped ventricular chamber. Surgical intervention, typically in infancy or childhood, aims to regulate pulmonary blood flow volume. In adulthood, untreated patients may experience limitations in physical activity and elevated morbidity due to persistent cyanosis and arrhythmias, notably after the Fontan procedure.

Background: V617F-mutated myeloproliferative neoplasms (MPN) exhibit abnormal proliferation of bone marrow progenitors and increased risk of thrombosis, specifically in splanchnic veins (SVT). The contribution of the endothelium to the development of the prothrombotic phenotype was explored.
Material And Methods: Plasma and serum samples from V617F MPN patients with (n=26) or without (n=7) thrombotic debut and different treatments, were obtained (n=33).
Impact of Wood Smoke Exposure on Aortic Valve Mineralization: Microvesicles as Mineral Conveyors in Patients with Coronary Stenosis.

Aortic valve calcification results from degenerative processes associated with several pathologies. These processes are influenced by age, chronic inflammation, and high concentrations of phosphate ions in the plasma, which contribute to induce mineralization in the aortic valve and deterioration of cardiovascular health. Environmental factors, such as wood smoke that emits harmful and carcinogenic pollutants, carbon monoxide (CO), and nitrogen oxide (NO), as well as other reactive compounds may also be implicated.

Background: We aimed to identify the central lifestyle, the most impactful among lifestyle factor clusters; the central health outcome, the most impactful among health outcome clusters; and the bridge lifestyle, the most strongly connected to health outcome clusters, across 29 countries to optimise resource allocation for local holistic health improvements.
Methods: From July 2020 to August 2021, we surveyed 16 461 adults across 29 countries who self-reported changes in 18 lifestyle factors and 13 health outcomes due to the pandemic. Three networks were generated by network analysis for each country: lifestyle, health outcome, and bridge networks.
