Life-course influences of poverty on violence and homicide: 30-year Brazilian birth cohort study.

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.

Intimate partner violence during pregnancy and quality of life in Southern Brazil: a cross-sectional study, 2022.

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.

Consumption of ultra-processed foods and mental health of pregnant women from the South of Brazil.

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.

The Prevalence of Dysphagia in Children with Laryngomalacia Pre and Postsupraglottoplasty: A Systematic Review with Meta-Analysis.

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.

Macrophage migration inhibitory factor favors Neospora caninum infection in mice.

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.

Folic acid supplementation during pregnancy and postpartum depressive symptoms.

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.

Child maltreatment associates with violent victimization in young adulthood: a Brazilian birth cohort study.

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.

Acolhimento de pessoas com deficiência auditiva na Atenção Primária à Saúde no município de Criciúma, Santa Catarina / Reception of the hearing impaired in Primary Health Care in the municipality of Criciúma, Santa Catarina

As pessoas com deficiência auditiva (DA) possuem barreiras a serem descontruídas quando o assunto é acesso aos serviços de saúde. Estas se dão devido à dificuldade na comunicação, falta de profissionais qualificados, ausência de intérprete da Língua Brasileira de Sinais (LIBRAS) dentre outros aspectos. O objetivo deste trabalho é analisar o acolhimento dos indivíduos com surdez na Atenção Primária em Saúde (APS). Trata-se de um estudo de métodos mistos com triangulação concomitante por meio de um estudo descritivo e quantitativo. O estudo foi realizado nas Unidades Básicas de Saúde (UBS) do município de Criciúma ­ Santa Catarina, participaram os gerentes das unidades de saúde, cirurgiões dentistas, enfermeiros e médicos. Foram entrevistados 43 profissionais de saúde de 44 UBS diferentes do município, dos quais os resultados apontaram frágeis condições de acolhimento e atendimento humanizado das pessoas com DA que procuram as unidades básicas de saúde. A comunicação predominante é de forma verbal e na maioria das vezes, conta com a presença de um familiar durante as consultas para facilitar essa comunicação. Alguns profissionais afirmaram que o DA não possui atendimento humanizado, inclusivo e resolutivo, e que os programas de capacitação deixariam os atendimentos mais humanizados. Em suma, existem inúmeras barreiras no acolhimento dos pacientes com DA na APS, sendo necessária a aprimoração das práticas para que seja desenvolvido um atendimento inclusivo, humanizado, acolhedor e integral.

The person with hearing loss (AD) has barriers to be deconstructed regarding access to health services. These are due to the difficulty in communication, lack of qualified professionals, and absence of interpreters of Brazilian Sign Language, among other aspects. This study aims to analyze the reception of individuals with deafness in Primary Health Care (PHC). This is a mixed methods study with concomitant triangulation through descriptive and quantitative analysis. The study was conducted in the Basic Health Units (BHU) of the municipality of Criciúma - Santa Catarina, with the participation of managers of health units, dental surgeons, nurses, and physicians. Participants were 43 health professionals from 44 different BHUs in the city, of which the results showed fragile conditions of reception and humanized care of people with AD who seek basic health units. The predominant communication is verbal and, in most cases, relies on the presence of a family member during the consultations to facilitate this communication. Some professionals stated that the DA lacks humanized, inclusive and resolutive care and that the training programs would make the care more humanized. In short, there are numerous barriers in the reception of patients with AD in PHC, and it is necessary to improve practices so that inclusive, humanized, welcoming, and integral care is developed.

Iron salt supplementation during gestation and gestational diabetes mellitus.

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.

Guideline for the management of fatigue in children and adolescents with cancer or pediatric hematopoietic cell transplant recipients: 2023 update.

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.

Self-recycling and partially conservative replication of mycobacterial methylmannose polysaccharides.

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.

Iron salt supplementation during gestation and gestational diabetes mellitus

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: 7.4-10.1) and 9.3% (95%CI: 7.4-11.6) 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: 0,7-1,3) and adjusted analysis (OR = 1.1; 95%CI :0,8-1,6). 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.

Iron Salts, High Levels of Hemoglobin and Ferritin in Pregnancy, and Development of Gestational Diabetes: A Systematic Review / Sais de ferro, níveis elevados de hemoglobina e ferritina na gravidez e o desenvolvimento de diabetes gestacional: Uma revisão sistemática

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.

Resumo Objetivo O objetivo deste estudo foi revisar sistematicamente a literatura sobre o uso de suplementos de ferro (não incluindo o ferro derivado da dieta), aumento dos níveis de hemoglobina e/ou ferritina e o risco de desenvolver diabetes mellitus gestacional (DMG). Fontes dos dados as bases de dados PUBMED, Cochrane, Web of Science, Scopus, Embase, Cinahl e Lilacs foram pesquisadas até abril de 2021. Seleção dos estudos Foram revisados 6.956 títulos e resumos, dos quais 9 preencheram os critérios finais de inclusão, totalizando 7.560 mulheres. Coleta de dados A extração de dados foi realizada por dois revisores independentes e as divergências foram resolvidas por um terceiro revisor. Síntese dos dados A qualidade metodológica dos ensaios controlados foi avaliada de acordo com as ferramentas da Colaboração Cochrane (ROB-2 e ROBINS-1) e para os estudos observacionais, foi utilizada a ferramenta de avaliação de qualidade do National Institutes of Health (NIH). Entre os 5 estudos observacionais, as mulheres com maiores níveis de hemoglobina ou ferritina apresentaram maior probabilidade de desenvolver DMG quando comparadas àquelas com níveis mais baixos nesses parâmetros. Entre os 3 ensaios clínicos randomizados, nenhum deles encontrou diferença significativa na incidência de DMG entre as mulheres dos grupos de intervenção e controle. No entanto, identificamos muitos riscos de viés e enormes diferenças metodológicas entre eles. Conclusão Com base nos estudos incluídos nesta revisão e devido aos importantes problemas metodológicos apontados, são necessários mais estudos de boa qualidade metodológica para melhor estabelecer a associação entre suplementação de ferro e DMG.
