Autophagy plays an important role in maintaining cell homeostasis through degradation of denatured proteins and other biological macromolecules. In recent years, many researchers focus on mechanism of autophagy in apicomplexan parasites, but little was known about this process in avian coccidia. In our present study. The cloning, sequencing and characterization of autophagy-related gene (Etatg8) were investigated by quantitative real-time PCR (RT-qPCR), western blotting (WB), indirect immunofluorescence assays (IFAs) and transmission electron microscopy (TEM), respectively. The results have shown 375-bp ORF of Etatg8, encoding a protein of 124 amino acids in E. selleck kinase inhibitor tenella, the protein structure and properties are similar to other apicomplexan parasites. RT-qPCR revealed Etatg8 gene expression during four developmental stages in E. tenella, but their transcriptional levels were significantly higher at the unsporulated oocysts stage. WB and IFA showed that EtATG8 was lipidated to bind the autophagosome membrane under starvation or rapamycin conditions, and aggregated in the cytoplasm of sporozoites and merozoites, however, the process of autophagosome membrane production can be inhibited by 3-methyladenine. In conclusion, we found that E. tenella has a conserved autophagy mechanism like other apicomplexan parasites, and EtATG8 can be used as a marker for future research on autophagy targeting avian coccidia.This thematic issue consists of 14 articles derived from studies of the BRISA birth cohort (Ribeirão Preto, State of São Paulo and São Luís, State of Maranhão, northeastern Brazil, a socially and economically less developed region). In these more than 40 years of existence, these cohorts have been able to document the increase in women's education, the improvement of health conditions, the creation of a public Unified Health System (SUS) that provides universal and free access to health care, eradication of hunger, and transition of the nutritional status characterized by a decrease in malnutrition rates and an increase in obesity in Brazil. Particularly in reproductive health, the country experienced a significant drop in fertility, a decrease in maternal and child mortality, and an increase in breastfeeding rates. Universal access to prenatal care and hospital delivery was accompanied by an excessive number of cesareans without clinical indication and early-term births and premature births, largely due to scheduled cesareans. Articles with a longitudinal and transversal methodological approach are presented, using structural equation analysis and propensity score, together with multivariate regressions, which gave a robust analytical treatment to articles in this thematic issue.Intrauterine growth restriction (IUGR) is related to a higher risk of neonatal mortality, minor cognitive deficit, metabolic syndrome, and cardiovascular disease in adulthood. In previous studies, genetic variants in the FTO (fat mass and obesity-associated) and PPARγ (peroxisome proliferator-activated receptor-gamma) genes have been associated with metabolic disease, body mass index, and obesity among other outcomes. We studied the association of selected FTO (rs1421085, rs55682395, rs17817449, rs8043757, rs9926289, and rs9939609) and PPARγ (rs10865710, rs17036263, rs35206526, rs1801282, rs28763894, rs41516544, rs62243567, rs3856806, and rs1805151) single-nucleotide polymorphisms (SNPs) with IUGR, through a case-control study in a cohort of live births that occurred from June 1978 to May 1979 in a Brazilian city. We selected 280 IUGR cases and 256 controls for analysis. Logistic regression was used to jointly analyze the SNPs as well as factors such as maternal smoking, age, and schooling. We found that the PPARγ rs41516544 increased the risk of IUGR for male offspring (OR 27.83, 95%CI 3.65-212.32) as well as for female offspring (OR=8.94, 95%CI 1.96-40.88). The FTO rs9939609 TA genotype resulted in a reduced susceptibility to IUGR for male offspring only (OR=0.47, 95%CI 0.26-0.86). In conclusion, we demonstrated that PPARγ SNP had a positive effect and FTO SNP had a negative effect on IUGR occurrence, and these effects were gender-specific.Gluten-related disorders affect 1% to 6% of the population, with complications and high risk of short and long-term morbidity and mortality. Since 2009, Brazil has a Clinical Protocol of Therapeutic Guidelines for Celiac Disease, but there are frequent complaints by persons with gluten-related disorders concerning the lack of healthcare professionals' knowledge of this topic and the difficulties related to healthcare, for both diagnosis and treatment. This study aimed to understand the weaknesses in healthcare perceived by persons with gluten-related disorders. An online qualitative survey was conducted in the Living Without Gluten group on Facebook, consulting the records saved by the group for 65 months, which totaled 510 posts and the respective comments. The data were grouped in categories, and thematic content analysis was performed, adopting the theoretical references on healthcare. The analysis revealed that the searches for diagnosis and adequate treatment were often described as a forced pilgrimage, resulting from shortcomings in healthcare, including lack of up-to-date knowledge on gluten-related disorders among the healthcare professionals and problems in the physician-patient relationship. Weaknesses in patient care and late diagnoses contribute to increasing the risk of complications and deaths. In this context, the Living Without Gluten group plays a leading role as a support group and network of solidarity, favoring increased awareness and empowerment of numerous Brazilians with gluten-related disorders.The aim of this study was to translate and cross-culturally adapt the Women's Use of the Internet in Pregnancy Questionnaire (WUIPQ) to Brazilian Portuguese and analyze the psychometric properties of the Preparation for Decision Making Scale (PDMS). This study consisted of the following steps translation, synthesis, back-translation, evaluation by the author of the original questionnaire, review by the panel of experts, and pretest of the WUIPQ. For such, Brazilian pregnant women and mothers who were members of Facebook groups participated in the study. We measured test-retest reliability as well as internal consistency and performed confirmatory factor analysis (CFA) of the B-PDMS. link2 In the pretest, 88.14% of the participants considered the items of the B-WUIPQ to be clear and pertinent, and 84.09% rated the sequence and organization of the questionnaire as excellent/good. The intraclass correlation coefficient and Cronbach's alpha coefficient for the B-PDMS were 0.850 (95%CI 0.791-0.899) and 0.91, respectively. CFA revealed factor loadings higher than 0.70 for most items, with a comparative fit index of 0.989, Tucker-Lewis index of 0.984, and root mean square error of approximation of 0.08 (95%CI 0.06-0.09). The B-WUIPQ presented cross-cultural adapted, and the B-PDMS demonstrated satisfactory psychometric proprieties to Brazilian pregnant women.The study aimed to estimate the prevalence of behavioral risk factors for cardiovascular diseases (CVDs) and factors associated with their accumulation in adolescents from the rural area of a municipality in Pelotas, Rio Grande do Sul State, Brazil. This was a cross-sectional school-based census-type study with a sample of 515 sixth to nineth-grade schoolchildren in 21 rural public schools in Pelotas. link3 The target behavioral risk factors were physical inactivity; irregular consumption of fruits, vegetables, and greens; initiation to alcohol consumption and smoking; and addition of salt to foods. The study outcome was the cluster score of behavioral risk factors, varying from 0 to 3 no behavioral risk factors for CVD or exposure to 1, 2, or ≥ 3 behavioral risk factors. Ordinal logistic regression was performed to assess the effect adjusted for individual characteristics on the accumulation of behavioral risk factors, using as the reference category individuals without any risk factor. Physical inactivity was the most prevalent risk factor (74.8%), followed by irregular consumption of fruits, vegetables, and greens (56.2%). Approximately 42% of the adolescents presented two behavioral risk factors, the most prevalent combination of which was physical inactivity and irregular consumption of fruits, vegetables, and greens (23%). The odds of accumulating two or more behavioral risk factors increased with age. The presence and simultaneity of behavioral risk factors is quite high among adolescents from the rural area of Pelotas, showing that they are exposed to the development of CVD. Interventions are needed to prevent the simultaneous occurrence of these risk factors.The article presents the results of a study on the experiences of adolescents that decided to terminate a pregnancy in the context of legal abortion services in Montevideo, Uruguay, from 2016 to 2018. The main objective was to examine the decision-making process and access to legal abortion from the perspective of the adolescent girls themselves. This involved analyzing circumstances, motives, and persons that influenced the decision and the ways this was handled in the health services. A cross-sectional, exploratory, and descriptive study was designed, based on a qualitative methodology. The main technique used for collecting the information was a semi-structured interview with 14 adolescents 17 to 19 years of age who had voluntarily terminated a pregnancy in public healthcare services. The motives for the abortion reveal the weight of socially accepted reasons, incorporated as their own. The interviews showed that the adolescent's mother plays an important role as the reference for the decision. The adolescents reported that they had made the decision to have the abortion before going to the health service. The results highlight the positive role of a legal framework that enables voluntary abortion services. The results help understand the experiences of adolescents facing a difficult life decision, the family's role, particularly that of the adolescent's mother, the legal framework's place in the decision, the weight of stigma and moral sanctions, and expectations towards care in health services.Recent studies on COVID-19 have focused on the pandemic's effects on public health and the biosafety controls and their socioeconomic implications. The current mixed-methods study takes a new look at the topic, combining qualitative and quantitative strategies to identify the social representations of media reception in a sector of the Colombian population during social isolation in the COVID-19 pandemic. The results indicate that these representations vary and are associated with the media channel and the effect the reception produces on mood and mental health. A total of 80 interviews and 1,068 online survey forms were applied in different regions of Colombia. The qualitative phase showed that the programs or messages received were represented positively when they came from audiovisual entertainment and contributed to the family unit and reduced stress during the lockdown. Meanwhile, media reception was represented negatively when the messages or news came from journalism or social networks and increased the misinformation, anxiety, and fear of contagion.
