ABSTRACT

BACKGROUND: Homicide is the leading cause of death among young people in Latin America, one of the world's most violent regions. Poverty is widely considered a key cause of violence, but theories suggest different effects of poverty, depending on when it is experienced in the life-course. Longitudinal studies of violence are scarce in Latin America, and very few prospective data are available worldwide to test different life-course influences on homicide. METHODS: In a prospective birth cohort study following 5914 children born in southern Brazil, we examined the role of poverty at birth, in early childhood, and in early adulthood on violence and homicide perpetration, in criminal records up to age 30 years. A novel Structured Life Course Modelling Approach was used to test competing life-course hypotheses about 'sensitive periods', 'accumulation of risk', and 'downward mobility' regarding the influence of poverty on violence and homicide. RESULTS: Cumulative poverty and poverty in early adulthood were the most important influences on violence and homicide perpetration. This supports the hypothesis that early adulthood is a sensitive period for the influence of poverty on lethal and non-lethal violence. Results were replicable using different definitions of poverty and an alternative outcome of self-reported fights. CONCLUSION: Cumulative poverty from childhood to adulthood was an important driver of violence and homicide in this population. However, poverty experienced in early adulthood was especially influential, suggesting the importance of proximal mechanisms for violence in this context, such as unemployment, organized crime, drug trafficking, and ineffective policing and justice systems.

ABSTRACT

The objective of this study is to evaluate the association between the consumption of ultra-processed foods (UPF) and the mental health of pregnant women from the South of Brazil. This is a cross-sectional study carried out in Criciúma, Brazil, through face-to-face interviews, from April to December 2022. Pregnant women aged 18 or older who underwent prenatal care in the forty-eight basic health care units of the municipality and who were in their third trimester of pregnancy were included. High consumption of UPF was considered as six or more items or subgroups of UPF consumed on the day before the interview, using the Nova-UPF screener. The mental health variables were depressive symptoms, stress, sadness and anxiety. Crude and adjusted analyses were conducted using the Fisher's exact test and the Poisson regression with robust variance. In total, 428 pregnant women were studied; most of them were aged between 20 and 25 years and were white. Pregnant women who presented high consumption of UPF were 1·42-fold (95 % CI 1·06, 1·92) more likely to experience anxiety and presented a prevalence 56 % (95 % CI 1·18, 2·07) higher of stress when compared with those who did not present high consumption of UPF. The prevalence of depressive symptoms and feelings of sadness was 1·31-fold (95 % CI 1·08, 1·60) and 3·41-fold (95 % CI 1·77, 6·58) higher among those with high consumption of UPF, respectively. The results suggest that diet quality is associated with the mental health of pregnant women. Promoting joint actions focused on food and nutritional education, and mental health, for pregnant women, is necessary.

ABSTRACT

OBJECTIVE: To analyze the association between intimate partner violence during pregnancy (IPVP) and quality of life (QOL). METHODS: A cross-sectional study was conducted with pregnant women receiving care in Primary Health Care in the municipality of Criciúma, Santa Catarina state, Brazil, in 2022; QOL was assessed in the physical, psychological, social relationship and environmental domains using WHOQOL-Bref instrument; IPVP was evaluated by means of the World Health Organization Violence Against Women; Crude and adjusted linear regression analyses were performed. RESULTS: A total of 389 pregnant women were evaluated; IPVP was observed in 13.6% of cases; in the adjusted analysis, IPVP remained associated with physical, psychological and social relationship domains; pregnant women who experienced IPVP had a reduction in their QOL score by 9.77, 11.07 and 8.95 points, respectively, when compared to those who did not experience IPVP. CONCLUSION: IPVP was associated with poorer QOL in the physical, psychological and social relationships domains. Health services equipped to address and prevent violence against pregnant women are essential. MAIN RESULTS: Intimate partner violence (IPV) was observed in 13.6% of pregnant women and was associated with poorer quality of life in the physical, psychological and social relationship domains. IMPLICATIONS FOR SERVICES: The results emphasize the need for an intersectoral approach in addressing the issue, with specialized healthcare centers for situations of violence integrated with social assistance and public security. PERSPECTIVES: Development of intersectoral policies and actions that strengthen existing ones and ensure social and healthcare assistance to pregnant women victims of violence and their children, given the negative impact of IPVP on quality of life.

ABSTRACT

Neospora caninum is a protozoan parasite with worldwide incidence, acting as a major cause of reproductive failures in ruminants and neuromuscular symptoms in dogs. Macrophage Migration Inhibitory Factor (MIF) is produced by several cell types and exhibits a central role in immune responses against intracellular pathogens. The present study aimed to comprehend the role of MIF in the relationship between N. caninum and its host. We used in vivo, in vitro and ex vivo experiments in a model of infection based on genetically deficient mice to analyze the infection kinetics and inflammatory markers. MIF production was measured in response to N. caninum during the acute and chronic phases of the infection. While Mif-/- mice survived lethal doses of NcLiv tachyzoites, sublethal infections in these mice showed that parasite burden was controlled in target tissues, alongside with reduced inflammatory infiltrates detected in lung and brain sections. TNF was increased at the initial site of the infection in genetically deficient mice and the MIF-dependent reduction was confirmed in vitro with macrophages and ex vivo with primed spleen cells. In sum, MIF negatively regulated host immunity against N. caninum, favoring disease progression.

ABSTRACT

Introduction Laryngomalacia is the most common congenital laryngeal alteration, with spontaneous resolution in most cases. However, in the face of more severe presentations of the disease, it is necessary to perform supraglottoplasty surgery. Studies have been dedicated to researching changes in swallowing in children with laryngomalacia before and after surgical intervention. Objectives To identify the prevalence of oropharyngeal dysphagia in children with pre and postsupraglottoplasty laryngomalacia. Data Synthesis A search strategy was developed with terms and entreterms to designate a population pediatric with laryngomalacia , exposure supraglottoplasty , and outcome frequency of dysphagia , adapted to the requirements of the main databases in the health area. The analysis of the records found was performed by two independent examiners and, in the end, 6 articles were included in the study. The articles found enabled a sample of 330 children with laryngomalacia, 311 of whom underwent supraglottoplasty. Among the included studies, 5 were grouped and meta-analyzed. After supraglottoplasty surgery, a 59% reduction in the prevalence of oropharyngeal dysphagia was identified, with high heterogeneity I 2 = 93%. Conclusion Despite the heterogeneity of the sample, the supraglottoplasty procedure significantly reduces the prevalence of dysphagia in children with laryngomalacia.

ABSTRACT

OBJECTIVE: To verify whether folic acid supplementation during pregnancy is associated with the occurrence of maternal depressive symptoms at three months postpartum, in the 2015 Pelotas Birth Cohort. METHODS: This study included 4,046 women, who were classified into three groups: did not use folic acid supplementation during pregnancy; used during only one trimester of pregnancy; and used for two or three trimesters. Depressive symptoms were assessed at three months postpartum using the Edinburgh Postnatal Depression Scale (EPDS), at cutoff points ≥ 10 (mild symptoms) and ≥ 13 (moderate to severe intensity). RESULTS: The overall prevalence of mild symptoms was of 20.2% (95%CI 19.0-21.5), and moderate and severe was 11% (95%CI 10.0-12.0). The prevalence of EPDS ≥ 10 was of 26.8% (95%CI 24.0-29.5) among women who did not use folic acid and 18.1% for both those who used it during one trimester of pregnancy (95%CI 16.1-20.1) and those who used it for two or three trimesters (95%CI 16.0-20.2). The prevalence of EPDS ≥ 13 was of 15.7% (95%CI 13.5-17.9) in those who did not use folic acid, 9.1% (95%CI 7.5-10.6) in those who used it for one trimester, and 9.4% (95%CI 7.8-11.0) in those who used it for two or three trimesters. In the adjusted analyses, there was no statistically significant association between the use of folic acid during pregnancy and the occurrence of depressive symptoms at three months postpartum. CONCLUSION: There was no association between folic acid supplementation during pregnancy and postpartum depression at three months.

ABSTRACT

BACKGROUND: Maltreatment in childhood may leave people vulnerable to further experiences of violence and more severe effects of stress later in life. Longitudinal studies of risk for violent victimisation after maltreatment are lacking in low- and middle-income countries. The objective of this study was to quantify the risk for violent victimization in the family and community in young adulthood following experiences of childhood maltreatment (experiences of physical, emotional and sexual abuse and neglect) up to age 15 years in an urban Brazilian population. METHODS: 3246 participants in a prospective, population-based birth cohort study in Pelotas, Rio Grande do Sul, Brazil, were assessed at birth, 15 and 22 years. Sociodemographic factors were reported by mothers at birth and adolescents at age 15 years. Maltreatment and violent victimisation were self-reported in confidential questionnaires at 15 and 22, respectively. Multinomial logistic regression analyses estimated the association between having experienced any maltreatment and later experiences of family and community violence in young adulthood (no adult violence, violence only in the family context, only in the community, or both violence in the family and community), adjusting for sociodemographic factors. RESULTS: 39% of females and 27% of males reported any maltreatment up to age 15 years. At 22 years, rates of past year violence in the family or community were 17.6% for females and 20.2% for males. Maltreatment was strongly associated with community violence (Females: OR = 2.96, CI = 1.83-4.80; Males: OR = 2.01, 95%CI = 1.01-4.00) and its co-occurrence with family violence (Females: OR = 2.33, 95%CI = 1.34-4.04; Males: OR = 3.20, 95%CI = 1.82-5.65) in young adulthood, after adjustment for background sociodemographic factors. CONCLUSION: Childhood maltreatment is an important risk factor for later violent victimisation in both the family and community context. The effects of repeated trauma through the life-course needs research and clinical attention.

ABSTRACT

OBJETIVE: To evaluate the association between the use of iron salts during the first two trimesters of gestation in non-anemic women and the development of gestational diabetes mellitus. METHODS: The study used maternal data from the 2015 Pelotas Birth Cohort. All non-anemic women at the 24th week of gestation (n = 2,463) were eligible for this study. Gestational diabetes mellitus was self-reported by women. Crude and adjusted logistic regression were performed considering level of significance = 0.05. RESULTS: Among the women studied, 69.7% were exposed to prophylactic iron supplementation in the first two trimesters of gestation. The prevalence of gestational diabetes mellitus among those exposed was 8.7% (95%CI: 7.4­10.1) and 9.3% (95%CI: 7.4­11.6) among those who were not exposed. Iron supplementation was not associated with increased risk of gestational diabetes mellitus in crude (OR = 0.9; 95%CI: 0,7­1,3) and adjusted analysis (OR = 1.1; 95%CI :0,8­1,6). CONCLUSIONS: The results suggest that routine iron use in non-anemic pregnant women does not increase the risk of developing gestational diabetes. This evidence supports the existing national and international guidelines, in which prophylactic iron supplementation is recommended for all pregnant women as soon as they initiate antenatal care in order to prevent iron deficiency anemia.

ABSTRACT

Objective was to update a clinical practice guideline (CPG) for the management of fatigue in children and adolescents with cancer or pediatric hematopoietic cell transplant recipients. We reconvened a multi-disciplinary and multi-national panel. While the previous 2018 CPG evaluated adult and pediatric randomized controlled trials (RCTs) to manage fatigue, this 2023 update revised previous recommendations based only on pediatric RCTs. Twenty RCTs were included in the updated systematic review. Physical activity significantly reduced fatigue (standardized mean difference -0.44, 95% confidence interval -0.64 to -0.24; n = 8 RCTs). Using the 2018 recommendations as a basis, the panel continued to make strong recommendations to use physical activity, and to offer relaxation, mindfulness or both, to manage fatigue in pediatric patients. Cognitive or cognitive behavioral therapies may be offered. Pharmacological approaches should not be routinely used. The panel made a new good practice statement to routinely assess for fatigue, ideally using a validated scale.

Introduction: The safest way of feeding babies with heart disease can be a challenge for the multidisciplinary team to choose. Objective: To identify the main swallowing difficulties in the different forms of feeding in infants with congenital heart disease. Methods: The guiding question was: "What are the main swallowing difficulties in the different forms of feeding in infants with congenital heart disease?". The population was defined as infants with heart disease, considering breastfeeding as exposure of interest and bottle feeding considered a comparison group. Swallowing difficulties were considered the outcome. Articles without language restriction were selected, regardless of the year of publication until April 2019, which presented in the title, abstract or body of the article a relationship with the objective of the research and the eligibility criteria, with an observational design. After data extraction, the measurements were transformed into percentages and described in a qualitative synthesis. Results: A total of 828 articles were found, and after analysis, 11 articles were included in total. The main difficulties presented by infants with heart disease at the mother's breast were coughing, choking, cyanosis, drop in peripheral oxygen saturation and incoordination between sucking, breathing and swallowing. The swallowing difficulties most found in the offer of the mother's breast were: cough, choking, cyanosis, drop in saturation, incoordination between sucking-breathing-swallowing, fatigue, oral leakage, prolonged feeding time, inadequate lip sealing, inadequate nipple grip, and altered cervical auscultation. Conclusion: Infants with heart disease have swallowing difficulties both in the mother's breast and in the bottle, with a higher frequency of presentations of difficulties being observed with the bottle.

ABSTRACT

The steep increase in nontuberculous mycobacteria (NTM) infections makes understanding their unique physiology an urgent health priority. NTM synthesize two polysaccharides proposed to modulate fatty acid metabolism: the ubiquitous 6-O-methylglucose lipopolysaccharide, and the 3-O-methylmannose polysaccharide (MMP) so far detected in rapidly growing mycobacteria. The recent identification of a unique MMP methyltransferase implicated the adjacent genes in MMP biosynthesis. We report a wide distribution of this gene cluster in NTM, including slowly growing mycobacteria such as Mycobacterium avium, which we reveal to produce MMP. Using a combination of MMP purification and chemoenzymatic syntheses of intermediates, we identified the biosynthetic mechanism of MMP, relying on two enzymes that we characterized biochemically and structurally: a previously undescribed α-endomannosidase that hydrolyses MMP into defined-sized mannoligosaccharides that prime the elongation of new daughter MMP chains by a rare α-(1→4)-mannosyltransferase. Therefore, MMP biogenesis occurs through a partially conservative replication mechanism, whose disruption affected mycobacterial growth rate at low temperature.

RESUMO OBJETIVO Verificar se a suplementação de ácido fólico durante a gestação está associada com a ocorrência de sintomas depressivos maternos aos três meses pós-parto, na Coorte de Nascimentos de Pelotas de 2015. MÉTODOS Este estudo incluiu 4.046 mulheres, que foram classificadas em três grupos: sem suplementação de ácido fólico na gestação; uso durante apenas um trimestre da gestação;e uso durante dois ou três trimestres. Os sintomas depressivos foram avaliados aos três meses pós-parto, através da Escala de Depressão Pós-Natal de Edimburgo (EPDS), nos pontos de corte ≥ 10 (sintomas leves) e ≥ 13 (intensidade moderada a grave). RESULTADOS A prevalência geral de sintomas leves foi de 20,2% (IC95% 19,0-21,5),e moderados e graves de 11% (IC95% 10,0-12,0). Entre as mulheres que não fizeram uso de ácido fólico, a prevalência de EPDS ≥ 10 foi de 26,8% (IC95% 24,0-29,5) e 18,1% tanto entre as que utilizaram durante um trimestre da gestação (IC95% 16,1-20,1), quanto entre as que utilizaram por dois ou três trimestres (IC95% 16,0-20,2). Já a prevalência de EPDS ≥ 13 foi 15,7% (IC95% 13,5-17,9) entre as que não utilizaram ácido fólico, 9,1% (IC95% 7,5-10,6) entre as que utilizaram durante um trimestre e 9,4% (IC95% 7,8-11,0) entre as que utilizaram por dois ou três trimestres. Nas análises ajustadas, não houve associação estatisticamente significativa entre o uso de ácido fólico na gestação e a ocorrência de sintomas depressivos aos três meses pós-parto. CONCLUSÃO Não se observou associação entre a suplementação de ácido fólico na gestação e depressão pós-parto aos três meses.

ABSTRACT

Abstract Objective The aim of this study was to systematically review literature on the use of iron supplements (not including iron derived from diet), increased levels of hemoglobin and/or ferritin, and the risk of developing gestational diabetes mellitus (GDM). Data source The following databases were searched, from the study's inception to April 2021: PUBMED, Cochrane, Web of Science, Scopus, Embase, Cinahl and Lilacs. Selection of studies A total of 6,956 titles and abstracts were reviewed, 9 of which met the final inclusion criteria, with 7,560 women in total. Data collection Data extraction was performed by two independent reviewers and disagreements were resolved by a third researcher. Data synthesis Methodological quality in controlled trials were assessed according to the Cochrane Collaboration tools (ROB-2 and ROBINS-1) and for the observational studies, the National Institutes of Health's (NIH) quality assessment tool was used. Among the 5 observational studies, women with a higher hemoglobin or ferritin level were more likely to develop GDM when compared with those with lower levels of these parameters. Among the 3 randomized clinical trials, none found a significant difference in the incidence of GDM among women in the intervention and control groups. However, we identified many risks of bias and great methodological differences among them. Conclusion Based on the studies included in this review, and due to the important methodological problems pointed out, more studies of good methodological quality are needed to better establish the association between iron supplementation and GDM.

ABSTRACT

OBJECTIVE: To evaluate social inequalities of Brazilians in alcohol consumption and cell phone use while driving motor vehicles. METHODS: Cross-sectional study conducted with people who drive (n=23,474) in 2019. The outcomes adopted were cell phone use and alcohol consumption while driving, associated with the variables gender, age group, skin color, education and macro-region of housing and analyzed using the slope index of inequality using logistic regression. RESULTS: The inequalities related to alcohol consumption and driving were identified in adults with brown skin color (7.8) linked to the North region (6.8). As for cell phone use while driving, they were higher for the younger age group (19.4) and individuals with higher education (27.1). CONCLUSION: Cell phone use and alcohol consumption while driving motor vehicles have social inequalities regarding the age group and education, and skin color and macro-region respectively.

ABSTRACT

Yellow fever (YF) is an infectious and acute viral haemorrhagic disease that triggers a cascade of host immune responses. We investigated the Th17 cytokine profile in the liver tissue of patients with fatal YF. Liver tissue samples were collected from 26 deceased patients, including 21 YF-positive and 5 flavivirus-negative patients, with preserved hepatic parenchyma architecture, who died of other causes. Histopathological and immunohistochemical analysis were performed on the liver samples to evaluate the Th17 profiles (ROR-γ, STAT3, IL-6, TGF-ß, IL-17A, and IL-23). Substantial differences were found in the expression levels of these markers between the patients with fatal YF and controls. A predominant expression of Th17 cytokine markers was observed in the midzonal region of the YF cases, the most affected area in the liver acinus, compared with the controls. Histopathological changes in the hepatic parenchyma revealed cellular damage characterised mainly by the presence of inflammatory cell infiltrates, Councilman bodies (apoptotic cells), micro/macrovesicular steatosis, and lytic and coagulative necrosis. Hence, Th17 cytokines play a pivotal role in the immunopathogenesis of YF and contribute markedly to triggering cell damage in patients with fatal disease outcomes.
