RESUMO
ABSTRACT: This study aims to evaluate the ratio of the number of cases of family violence and violence by a known person, over the four surveys that took place in 2006, 2007, 2009, and 2011, within the population treated in the Brazilian health services, according to demographic and socioeconomic characteristics. Data from the Vigilância de Violências e Acidentes survey was used. The variables age, victim sex, aggressor sex, race, and schooling level were considered in the analysis. This study pointed out decreasing trend in the number of violence-related care within the older age group. The number of familial violence-related care per victim sex was higher for male victims when the aggressor was female, and conversely, it was higher for female victims when the aggressor was male. The number of violence-related care was mostly higher in non-White people than in White. People with low schooling levels showed the highest ratio of the number of violence-related care.

This paper is a theoretical discussion that explores medical confidentiality within the context of Brazilian law about underage consent sex. Brazilian law determines that the age of consent for sexual intercourse is 14 years. Before this limit, physicians should report the sexual activity of adolescents, breaking the confidentiality of the consultation. The medical code of ethics prohibits the breach of professional confidentiality of a minor patient, including their parents or legal representatives, unless a lack of disclosure may cause harm to the patient. The legal issue seems to go beyond the ethical issue; however, the breach of confidentiality can cause more risks than benefits by removing these adolescents from health services. The law aims to protect the sexual dignity of teenagers under 14 years old, but the particularities of each case must be considered, and flexibility concerning medical confidentiality should be included.

OBJECTIVE: To evaluate the association between treatment and mother-to-child transmission of acute Toxoplasma gondii infection in pregnancy. METHODS: This was a concurrent cohort study of 26 pregnant women diagnosed with acute toxoplasmosis. Transmission of T. gondii to the fetus was characterized by detection of the parasite in the amniotic fluid by polymerase chain reaction (PCR). Congenital toxoplasmosis was diagnosed by a positive serological test for IgM, intracranial calcification, chorioretinitis, hydrocephalus, and/or microcephaly in the newborn. RESULTS: There was direct correlation between acute toxoplasmosis and low socioeconomic status and inadequate hygienic/health conditions. The MCT rate in adequately and inadequately treated patients was 17.4% and 33.3%, respectively. PCR analysis of the amniotic fluid was performed for 15 women, with 1 positive result; the pregnant woman was adequately treated, and her infant had no complications. Congenital infection occurred in 4 newborns, who had hydrocephalus, intracranial calcifications, and chorioretinitis. Cerebrospinal fluid alteration was found in 3 of the 16 infants tested. Transmission was more frequent in the third quarter of pregnancy (Pâ¯=â¯0.04). CONCLUSION: The rate of mother-to-child transmission of T. gondii is higher in untreated pregnant women and those who acquired the infection later in pregnancy.

BACKGROUND: The COVID-19 pandemic has significantly impacted global health, with diverse factors influencing the risk of death among reported cases. This study mainly analyzes the main characteristics that have contributed to the increase or decrease in the risk of death among Severe Acute Respiratory Syndrome (SARS) cases classified as COVID-19 reported in southeast Brazil from 2020 to 2023. METHODS: This cohort study utilized COVID-19 notification data from the Sistema de Vigilância Epidemiológica (SIVEP) information system in the southeast region of Brazil from 2020 to 2023. Data included demographics, comorbidities, vaccination status, residence area, and survival outcomes. Classical Cox, Cox mixed effects, Prentice, Williams & Peterson (PWP), and PWP fragility models were used to assess the risk of dying over time. RESULTS: Across 987,534 cases, 956,961 hospitalizations, and 330,343 deaths were recorded over the period. Mortality peaked in 2021. The elderly, males, black individuals, lower-educated, and urban residents faced elevated risks. Vaccination reduced death risk by around 20% and 13% in 2021 and 2022, respectively. Hospitalized individuals had lower death risks, while comorbidities increased risks by 20-26%. CONCLUSION: The study identified demographic and comorbidity factors influencing COVID-19 mortality. Rio de Janeiro exhibited the highest risk, while São Paulo had the lowest. Vaccination significantly reduces death risk. Findings contribute to understanding regional mortality variations and guide public health policies, emphasizing the importance of targeted interventions for vulnerable groups.

Although variation between observers in the assessment of the Apgar score, it remains a useful indicator of the general conditions of the newborn. This is a cross-sectional study based on population of live births in Brazil in 1999 and biennium 2018-2019. All declarations of live births (DNV) obtained from the Live Births System database were accessed. Frequencies were compared between groups using Pearson's chi-square test and multivariate logistic regression analysis was performed. A statistical significance level of 0.05 was considered. We included 9.050.521 DNVs in our research. We found that 2,1% of newborns had 5th minute Apgar < 7 in 1999 compared with 0,9% in 2018-2019. Multivariate analysis shows that twins and teenage pregnancy are no longer risk factors. Among risk factors, we observed an increase in prematurity, low birth weight and congenital anomalies. An improvement in maternal markers was observed, especially increase in the number of prenatal consultations and schooling. Such findings demonstrate the importance access and adequate prenatal care and improved socioeconomic conditions as effective strategy to reduce neonatal morbidity and mortality.
Apesar da variação entre observadores na avaliação do escore de Apgar, ele permanece um indicador útil das condições gerais do recém-nascido. O presente trabalho é um estudo de corte transversal baseado na população de nascidos vivos no Brasil no ano de 1999 e no biênio 2018-2019. Foram avaliadas todas as declarações de nascidos vivos (DNV) obtidas a partir do banco de dados do Sistema de Informações sobre Nascidos Vivos. As frequências foram comparadas entre os grupos por meio do teste qui-quadrado de Pearson e foi realizada análise de regressão logística multivariada. Adotou-se nível de significância estatística de 0,05. Foram analisadas 9.050.521 DNVs em nossa pesquisa. Constatamos que 2,1% dos recém-nascidos tiveram Apgar de 5º minuto < 7 em 1999, em comparação com 0,9% em 2018-2019. A análise multivariada indicou que gemelidade e gravidez na adolescência deixaram de ser fatores de risco para Apgar de 5º minuto < 7. Entre os fatores de risco, nota-se aumento da prematuridade, baixo peso ao nascer e anomalias congênitas. Observou-se melhoria de marcadores maternos, em especial o aumento do número de consultas pré-natais e escolaridade. Tais achados mostram a importância de acesso e seguimento pré-natal adequado e investimento em melhores condições socioeconômicas como estratégia eficaz para redução de morbimortalidade neonatal.

OBJECTIVE: This study aimed to describe the current situation of sexual aggression and assess the adhesion to ambulatory care follow-up. METHODS: This is a cross-sectional study involving female children and adolescents aged 0-19 years, treated at the Center for Multiprofessional Care of Sexual Violence of the General Hospital of Nova Iguaçu, from 2014 to 2018. RESULTS: Of the 453 children and adolescents, 264 (58.3%) were <14 years of age and 189 (41.7%) were 14-19 years of age. In both groups, 78% were black. School delay of >2 years was found in 15.6% of children in the age group <14 years and 40.5% of adolescents in the age group 14-19 years [p<0.001; OR=3.7 (2.1-65)]. In girls aged £13 years, abuse usually occurred at home (73.2%), which was perpetrated by one aggressor (91%) and known to the victim (91.2%). In adolescents aged ≥14 years, 84.1% of rapes occurred outside the home, practiced by one aggressor (74.8%), 57.8% were unknown, and in 91.2% of cases, there was use of physical force and/or verbal threats. The victims aged <14 years have 14 times more chance of experiencing aggression within the family setting [p<0.001; OR=14.3 (8.2-25.6)] and 16 times more chance of experiencing aggression from known persons [p<0.001; OR=16.2 (9.2-29.8)]. On the contrary, adolescents aged ≥14 years have three times more chance of being abused by more than one aggressor [p<0.001; OR=3.3 (1.8-6.1)]. CONCLUSION: Black girls, especially those aged <14 years, are in a situation of greater vulnerability for sexual violence, have less adhesion to follow-up, and often experience aggression in the household setting.

OBJECTIVE: The aim of this study was to assess the rate of repeated pregnancy in adolescence and its association with early marriage and education level. METHODS: This is a cross-sectional study conducted by searching the Live Births Data System. The study included all adolescents in the age group 10-19 years with live births from 2015 to 2019 (n=2,405,248), divided into three groups: G1: primiparas; G2: with 1 previous pregnancy; and G3: with two or more previous pregnancies. RESULTS: Total repeated pregnancies remained stable, along the years. In the age group 10-14 years, the decrease in the period was from 5.0 to 4.7%, whereas in the age group 15-19 years, it was from 27.8 to 27.3%. Being married or in a stable union increases by 96% the chance of repeated pregnancy in the age group 10-14 years (p<0.001; OR=1.96; 95% confidence interval [CI] 1.85-2.09). In the age group 15-19 years, the chance of repeated pregnancy among the married or in stable union increased 40% (p<0.001; OR=1.40; 95%CI 1.39-1.41)). Girls aged 10-14 years with an education level of<8 years had a 64% higher chance of repeated pregnancy (p<0.001; OR=1.64; 95%CI 1.53-1.75), and among those aged 15-19 years, there was a 137% higher chance of repeated pregnancy (p<0.001; OR=2.37; 95%CI 2.35-2.38). CONCLUSION: Repeated pregnancy in adolescence in Brazil remains very high over the years. There is an association between low education level and early marriage with repeated pregnancies in adolescence.

The aim of this study was to estimate the rate of Mother-to-child Transmission (MTCT) of HIV to neonates in a reference university hospital in Sao Luis city, the capital of Maranhao State (MA), evaluating MTCT-associated factors. A retrospective cohort study based on data from the Notifiable Diseases Data System (SINAN) was carried out and included all HIV-exposed neonates notified from 2013 to 2017 by the university hospital. The study population comprised 725 HIV-exposed neonates, of whom 672 neonates were exposed and uninfected, and 53 were exposed and infected. The estimated rate of MTCT in the period of 2013 to 2017 was 7.3%. Most pregnant women were ≥ 20 years old (86.9%), reported ≥ 8 years of schooling (53.2%), reported full-time or independent paid work (46.9%) and were residents in other cities of the state (61.7%). Regarding healthcare, 86.3% received prenatal care, 74.6% received Antiretroviral Therapy (ART) as prophylaxis during pregnancy, 81.8% received ART prophylaxis during childbirth and 78.1% underwent cesarean section. Among the neonates, 92.8% received ART prophylaxis and 94.3% were not breastfed. Despite these variables, the 7.3% MTCT rate found in this study makes it clear that the interventions recommended by the Ministry of Health were not fully adopted.

This study aims to identify a set of symptoms that could be predictive of SARS-CoV-2 cases in the triage of Primary Care services with the contribution of Qualitative Comparative Analysis (QCA) using Fuzzy Sets (fsQCA). A cross-sectional study was carried out in a Primary Health Care Unit/FIOCRUZ from 09/17/2020 to 05/05/2021. The study population was suspect cases that performed diagnostic tests for COVID-19. We collected information about the symptoms to identify which configurations are associated with positive and negative cases. For analysis, we used fsQCA to explain the outcomes "being a positive case" and "not being a positive case". The solution term "loss of taste or smell and no headache" showed the highest degree of association with the positive result (consistency = 0.81). The solution term "absence of loss of taste or smell combined with the absence of fever" showed the highest degree of association (consistency = 0,79) and is the one that proportionally best explains the negative result. Our results may be useful to the presumptive clinical diagnosis of COVID-19 in scenarios where access to diagnostic tests is not available. We used an innovative method used in complex problems in Public Health, the fsQCA.

This study aimed to analyze the role of period, geographic and socio demographic factors in cancer-related mortality by prostate, breast, cervix, colon, lung and esophagus cancer in Brazilians capitals (2000-2015). Ecological study using data of Brazilian Mortality Information. Multilevel Poisson models were used to estimate the adjusted risk of cancer mortality. Mortality rate levels were higher in males for colon, lung and esophageal cancers. Mortality rates were highest in the older. Our results showed an increased risk of colon cancer mortality in both sexes from 2000 to 2015, which was also evidenced for breast and lung cancers in women. In both genders, the highest mortality risk for lung and esophageal cancers was observed in Southern capitals. Midwestern, Southern and Southeastern capitals showed the highest mortality risk for colon cancer both for males and females. Colon cancer mortality rate increased for both genders, while breast and lung cancers mortality increased only for women. The North region showed the lowest mortality rate for breast, cervical, colon and esophageal cancers. The Midwest and Northeast regions showed the highest mortality rates for prostate cancer.

OBJECTIVE: The aim of this study was to analyze the occurrence and risk factors associated with infections during pregnancy in patients with systemic lupus erythematosus. METHODS: This is a retrospective cohort study using the data of pregnant women who were followed up between 2011 and 2018 at a university hospital. RESULTS: The data of 221 pregnant women with systemic lupus erythematosus were analyzed. The incidence of infections was 22.6% (50/221), with the urinary tract being the most frequent site of infection (32/221, 14.5%) followed by the respiratory tract (15/221, 6.8%). The bivariate analysis showed that active disease, hematological systemic lupus erythematosus, reduced complement, and use of prednisone ≥5 and ≥10 mg increased the chance of infection during early pregnancy (p=0.05, p=0.04, p=0.003, p=0.008, and p=0.02, respectively), while disease activity and anti-DNA positivity increased it at the end of pregnancy (p=0.03 and p=0.04, respectively). Prednisone at a dose ≥5 mg increased the chance of infection in the beginning (p=0.01) and at the end of pregnancy (p=0.008). Multivariate analysis showed that increasing the dose of prednisone from 5 to 10 mg tripled the chance of developing infections in pregnant women with lupus (p=0.02). CONCLUSION: The study showed an increased chance of infections in pregnant women with systemic lupus erythematosus and it was associated with the use of prednisone.

OBJECTIVE: Compare official data on notifications of sexual violence against girls aged 10 to 13 years with data on pregnancy for the same age group between 2012 and 2018. METHODS: This is an epidemiological, descriptive, cross-sectional study with data from the Department of Informatics of the Unified Health System (DATASUS) on violence against and pregnancy of girls aged 10 to 13 years from 2012 to 2018. Data on sexual violence were accessed in the Health Information System (SINAN); on pregnancy, in the Live Births Information System (SINASC), on fetal deaths, in the Mortality Information System (SIM), and on abortions, in the Hospital Admission System (SIH). RESULTS: Between 2012 and 2018, out of 136,387 pregnancies, there were 120,185 live births and 15,402 interrupted pregnancies by abortions or fetal deaths of mothers who became pregnant aged 13 years or younger. In the same period, SINAN received 46,548 notifications of sexual abuse against girls aged 10 to 13 years. The number of girls who became pregnant before the age of 14, victims of statutory rape, was 2.9 times higher than the number of cases notified to SINAN. CONCLUSION: The lack of adequate notification of statutory rapes in Brazilian official statistics leads to the underestimation of its magnitude.

OBJECTIVE: This study aimed to evaluate the frequency of late pregnancies in Brazil, the age-specific fertility rate (ASFR) in the regions, the rate of prematurity, and the rate of low birth weight (LBW) and their association with advanced maternal age compared with 20-34-year-old women. METHODS: This was a cross-sectional study conducted by searching the Information System on Live Births (Sistema de Informações Sobre Nascidos Vivos [SINASC]). Data from 1995 to 2018 were collected, and pregnant women were divided into three categories based on their age range: 35-39, 40-44, and ≥45 years. The study calculated the frequency of deliveries of mothers of advanced age in Brazil, the ASFR, and the rates of prematurity and LBW in each group. CONCLUSIONS: The frequency of deliveries and ASFR ≥35 years increased between 1995 and 2018. The chances of prematurity and LBW were higher with increased maternal age.

OBJECTIVE: This study aimed to assess live birth frequency and age-specific fertility rates (ASFR) in the period 1996-2018 and the number of pregnancies at <14 years old in the period 2012-2018. METHODS: This was a cross-sectional study conducted by search on Live Births Data System (SINASC/DATASUS) database. RESULTS: There was a variation in ASFR in Brazil of 0.78 in 1996 to 0.87 in 2018 (+11.5%). In the north region, it increased from 1.28 to 1.66 in 2018. In the northeast region, it increased from 0.72 to 1.66 (+131%) in 1996-2011, but decreased to 1.31 in 2018 (-21% in relation to 2011). When comparing 1996 and 2018, in the southeast region, there was a 22% decrease; in the south region, it was 48.2%; and in the Center-West region, it was 34%; but in the north region, there was a 29.7% increase, and in the northeast region, it was 81.9%. When adding girls who became pregnant aged 13 years and gave birth at 14, there was a threefold increase in the rate. CONCLUSIONS: The increase of pregnancies in <14 years old in less developed regions of Brazil shows an association with socioeconomic factors and reveals the severe problem of rape of vulnerable persons in the country.

OBJECTIVE: The aim of this study was to evaluate the frequency of teenage pregnancy in all Brazilian regions and states in the period of 2000-2019 among two age groups, namely, 10-14 and 15-19 years old, and correlate it with the human development index. METHODS: A cross-sectional study was performed by using the data from the Live Birth Info System from the National Health System's database. RESULTS: The percentage of live births from teenage mothers (age 10-19 years) in Brazil decreased by 37.2% (i.e., 23.4 in 2000 to 14.7% in 2019) in all regions. Amazonas and Maranhão were the only states to show increased fertility rates for teens in the age group of 10-14 years. The fertility index decreased from 80.9-48% in all states among mothers aged 15-19 years. Only the Southeast and South regions showed levels below the Brazilian average (i.e., 38.2 and 39%, respectively). The proportion of live birth showed an inversely proportional trend to the human development index score. CONCLUSIONS: Brazil shows a decline in the percentage of live birth among adolescent mothers and the fertility rate. Live birth is inversely proportional to the human development index score. However, the teenage pregnancy numbers are still high, with great regional inequality in the country.

BACKGROUND: this study aims to estimate the rate of death by cancer as a result of Radio Base Station (RBS) radiofrequency exposure, especially for breast, cervix, lung, and esophagus cancers. METHODS: we collected information on the number of deaths by cancer, gender, age group, gross domestic product per capita, death year, and the amount of exposure over a lifetime. We investigated all cancer types and some specific types (breast, cervix, lung, and esophagus cancers). RESULTS: in capitals where RBS radiofrequency exposure was higher than 2000/antennas-year, the average mortality rate was 112/100,000 for all cancers. The adjusted analysis showed that, the higher the exposure to RBS radiofrequency, the higher cancer mortality was. The highest adjusted risk was observed for cervix cancer (rate ratio = 2.18). The spatial analysis showed that the highest RBS radiofrequency exposure was observed in a city in southern Brazil that also showed the highest mortality rate for all types of cancer and specifically for lung and breast cancer. CONCLUSION: the balance of our results indicates that exposure to radiofrequency electromagnetic fields from RBS increases the rate of death for all types of cancer.

Introduction Aim of the study was to evaluate the association between microcephaly and acute infection with Zika virus (ZIKV) in pregnant women in the state of Rio de Janeiro, Brazil. Infection was confirmed by laboratory testing. Materials and Methods A cross-sectional retrospective study of pregnant women with symptoms occurring between 2015 and 2016 suggestive of acute ZIKV infection was carried out, with confirmation of infection done by blood or urine RT-PCR. The relative proportions of categorical variables were calculated for two distinct groups: pregnant women whose newborns had microcephaly and pregnant women who gave birth to infants without microcephaly. Confidence intervals with a 95% level of agreement were estimated for the relative ratios. Results A total of 1609 pregnant women with a mean age of 26.4 ± 6.5 years were evaluated. As regards the time of acute infection, 19.6% (316) of cases occurred in the first trimester of pregnancy. Nineteen (76%) of the 25 cases with microcephaly (1.5%) were associated with an infection contracted in the first trimester of pregnancy (p < 0.001, OR = 13.7, 95% CI: 5.6â-â37.7). 48% (12/25) of the newborns with microcephaly had a birth weight of < 2500 grams, while only 7% (116/1597) of the group of newborns without microcephaly had a similarly low birth weight (p < 0.001, OR = 11.7, 95% CI: 5.2â-â26.2). Logistic regression showed that a birth weight of < 2500 g (OR = 12.54) and ZIKV infection in the first trimester of pregnancy (OR = 14.05) were associated with microcephaly (area under ROC curve = 0.86). Conclusion Acute ZIKV infection in the first trimester of pregnancy and low birth weight are associated with microcephaly.
RESUMO
OBJECTIVE: To analyze the degree of knowledge of Brazilian adolescents regarding emergency contraception (EC) such as correct administration, frequency of use, efficacy, mechanism of action, adverse effects, and complications. METHODS: Cross-sectional study. Adolescents aged 11-19 years answered a questionnaire containing questions about sexuality, knowledge, and use of EC. RESULTS: Out of 148 adolescents who were interviewed 8% did not know about the EC. Among the sexually active, 56.7% used EC at least once. The chance of obtaining EC information with friends triples between 15-19 years old [p=0.04; OR=3.18 (1.08-10.53)]. Most used single-dose EC. They said that EC prevents 80% of pregnancy and should be used within 72 hours after unprotected sex. Only 41.2% between 10-14 years old and 82.4% between 15-19 years old know that it prevents fertilization. As reasons for using they cited: rape and unprotected sex in 58.3% of those aged 10-14 years old and 79.6% between 15-19 years old. About side effects, 58.8% of 10-14 years old and 17.6% of those aged ≥15 years old could not answer, but 60.5% between 15-19 years old mentioned nausea and vomiting. A significant portion (17.6-41.2%) believes that EC causes abortion, cancer, infertility, and fetal malformations. Over 80% of the girls agree that it can cause menstrual irregularity. CONCLUSION: Knowledge regarding EC is not satisfactory, especially regarding its risks, regardless of the age and education of the groups evaluated. Improved knowledge may lead to greater adherence to EC and lead to a reduction in unplanned pregnancies.

BACKGROUND: Adolescent dating violence (ADV) is highly prevalent and can have serious health consequences, including homicides, and be a predictor of intimate partner violence in adulthood. This review aims to systematize the knowledge produced in recent empirical investigations in health that focus on the causes and consequences of ADV to subsidize new research and prevention programs. METHODS: Review of studies published in PubMed over the last five years through MeSH Database: "Intimate Partner Violence" AND "Adolescent" NOT "prevention and control" NOT "Adult". RESULTS: We analyzed 35 papers, of which 71.4% were developed in the USA. Some studies have shown prevalence greater than 50% in both genders, both as victims and perpetrators, with more serious consequences for females. Three main thematic cores were identified in the studies: ADV-related vulnerabilities, circularity of violence and ADV-associated health problems. Data indicate that ADV is deep-seated in the patriarchal culture and is more frequent in connection with racism, heterosexism and poverty. It occurs in a circular way and is linked to other forms of violence in different contexts (family, school, community and social media). It is associated with health problems such as depression, anxiety, low self-esteem, alcohol and drugs abuse and unprotected sex. CONCLUSIONS: The knowledge produced in the studies reviewed reveals the urgency and importance of implementing early preventive actions in schools, involving families and the community. These should focus on the deconstruction of current cultural gender patterns, based on their historical origin, in order to support emancipatory and liberating pedagogical approaches.

OBJECTIVE: To synthesize the knowledge produced in studies about the association between violence and STI during pregnancy. METHODS: In this systematic review, we conducted basic activities of identification, compilation, and registration of the trials. The instruments of data collection were studies that investigated, explicitly, relationships between violence, gestation, and STI, from July 2012 to July 2017, using PubMed, Cochrane Library, SciELO, and LILACS. RESULTS: In all, 26 articles were chosen to form the basis of the analysis of this study. The relationship between violence and STI was observed in 22 of the 26 studies, and in eight of them, the violence was practiced during the gestation period. In two studies, there was no evidence of this relationship. In one study, the lack of care for STI was attributed to the unpreparedness of health professionals. Mental disorders were cited as resulting from STI in three articles and in another as a result of violence. One study found more frequent violence against adolescents, while two others cited gestation as a protective factor. CONCLUSIONS: IPV combines characteristics that have a different expression when the woman is in the gestational period. The literature points to a relationship between IPV against women and the presence of STI. The monitoring of pregnancy, whether in the prenatal or postpartum period, offers unique opportunities for the health professional to identify situations of violence and thus provide assistance.
