Maternal mortality in adolescents and young adults: temporal trend and correlation with prenatal care coverage in the state of Bahia, Brazil, 2000-2020

MAIN RESULTS

From 2000 to 2020, maternal mortality among adolescents and young adults showed a decreasing trend in the state of Bahia. It could be seen an inverse and significant correlation between the highest number of prenatal care visits and maternal mortality in the studied groups.

IMPLICATIONS FOR SERVICES

The study suggests the importance of quality obstetric care during prenatal, childbirth, and postpartum period for reducing maternal mortality among adolescents and young adults, especially from preventable causes.

PERSPECTIVES

Improving the records of causes of death on information systems, enhancing obstetric care, and investing in sexual and reproductive health policies aimed at adolescents may contribute to the reduction of maternal deaths.

OBJECTIVE

to analyze the temporal trend of maternal mortality and correlate it with prenatal care coverage among adolescents and young adults, state of Bahia, Brazil, 2000-2020.

METHODS

this was an ecological time-series study and correlation between maternal deaths and prenatal care visits in 10-19 and 20-24 age groups, using the Mortality Information System; the trend analysis was performed by means of Prais-Winsten regression, according to race/skin color, timing and causes of death; and Spearman coefficient was used for correlation.

RESULTS

in the study period, 418 deaths among adolescents and 574 among young adults were recorded; maternal mortality ratio was 59.7 and 63.2 deaths/100,000 live births, with a significant decreasing trend (-2.2% and -2.9% respectively); it could be seen an inverse correlation between a higher number of prenatal care visits and maternal mortality in the age groups.

CONCLUSION

maternal mortality showed a decreasing trend in the study period, but with high proportions of death; there was a significant correlation between prenatal care coverage and maternal mortality among adolescents and young adults.

Rhinal and hippocampal event-related potentials as epileptogenic zone markers in the pre-surgical evaluation of temporal epilepsies: a systematic review

BACKGROUND

 Cognitive event-related potentials (ERPs) allow for lateralization of the epileptogenic zone (EZ) to estimate the reserve of memory in the contralateral non-epileptogenic hemisphere, and to investigate the prognosis of temporal lobe seizure control in unilateral temporal lobe epilepsy (TLE).

OBJECTIVE

 To define the accuracy of cognitive evoked anterior mesial temporal lobe (AMTL-N400) and P600 potentials in detecting the epileptogenic zone in temporal lobe epilepsy (TLE), and second, to evaluate the possibility of using them as markers of cognitive outcome.

METHODS

 The systematic review using Medline/PubMed, Embase, and Lilacs database was conducted in September 2021. Only articles published in English from 1985 to June 2021 were included. We searched for studies with: (1) depth intracranial electroencephalography (iEEG) recordings analysis of rhinal and hippocampal activity (2) correlations between ERP results obtained in the mesial temporal regions (AMTL-N400 and P600) and the epileptogenic zone.

RESULTS

 Six out of the seven studies included in this review defined the laterality of the epileptogenic zone (EZ) during presurgical investigation using ERPs. One study showed that the contralateral AMTL-N400 predicts seizure control. Another study found correlation between the amplitudes of the right AMTL-N400 and postoperative memory performance.

CONCLUSIONS

 There is evidence that the reduced amplitude of the AMTL-N400 has high accuracy in identifying the epileptogenic zone, as it does in estimating the extent of seizure control and memory impairment in postoperative patients.

MTL-P300 as a marker of the epileptogenic zone and hippocampal functionality in the presurgical evaluation of temporal lobe epilepsy: a systematic review

BACKGROUND

In the past twenty years, there has been an increasing interest among neuroscientists and physicians in mapping the cortical areas involved in the epileptogenic zone (EZ) through event-related potentials (ERPs) that enable the evaluation of the functional preservation of these areas. The present review is an update on publications on this topic.

OBJECTIVE

To investigate the accuracy of the cognitive evoked of the medial temporal lobe P300 (MTL-P300) potential in detecting the EZ in temporal lobe epilepsy (TLE).

METHODS

The systematic review of articles on the PubMed, Embase and Lilacs databases was conducted between February and December 2020. Articles published in English from 1985 to December 2020 were included. Additional studies were identified by searching the references of the selected studies and review articles. The studies were included for the following reasons: in-depth intracranial electroencephalography (iEEG) analysis of hippocampal activity; investigations of patients with TLE; and correlations between regarding the ERP results obtained in the temporal regions (MTL-P300) and the EZ.

RESULTS

In the three studies analyzed, the authors were able to define the laterality of the EZ during the preoperative investigation through the MTL-P300 results. The sensitivity of this method was of ∼ 70% to 80%, and the specificity between 70% and 94.7%. One of the limitations of the present review was the low number of studies.

CONCLUSION

There is evidence that the reduced amplitude of the MTL-P300 has high specificity in identifying the EZ, and this is a good marker for diagnosis in unilateral TLE. The low sensitivity and negative likelihood ratios negative that a normal MTL-P300 response does not exclude the epileptogenicity of the hippocampus.

Factors associated with Specific Hypertensive Gestation Syndrome (SHGS) in postpartum adolescent and young adult mothers in the Northeast of Brazil: a multiple analysis of hierarchical models

Abstract Objectives: to analyze possible associations between Specific Hypertensive Gestation Syndrome (SHGS) and sociodemographic, prenatal, and delivery characteristics of young adult and teenage mothers. Methods: a hospital-based cross-sectional study and regional level, gathered from 54 municipalities in the Northeast region of Brazil from 2011-2012, using records from the National Survey, "Born in Brazil". A theoretical conceptual model with three-level hierarchy was established, with SHGS being the outcome variable. A multivariate analysis was performed from the bivariate analysis and p-value, with a significance of < 0.2 by the Wald test. Results: of the 2,960 adolescents and young adults included in the study, 135 (4.6%) developed HSP. The mothers without a partner had 50% (OR=1.53) greater chance of presenting this pathology; while those without adequate schooling for age presented 90% higher chance (OR = 1.86) and those with a prior clinical risk factor, the chance of presenting the outcome was 21 times the chance of those without this antecedent (OR = 21.72). Conclusions: significant associations were identified between SHGS and postpartum adolescents and young adults without a partner, with low schooling and prior clinical risk, signaling the importance of investments in the quality of prenatal care and labor of the most vulnerable groups.

[Sexual violence and co-occurrences suffered by children and adolescents: study of incidents over a decade]

The study analyzes the evolution of the incidence of sexual violence (SV) and co-occurrences between 2001 and 2010. The records of the Guardianship Councils in Feira de Santana, State of Bahia, Brazil were used and the incidence rates and graphs of the events during the period were calculated. Of the total of the different types of violence, 21.8 % involved co-occurrences, the majority being female, most frequently during adolescence. There was a high proportion of abuse in male children, with most offenders bring family members or acquaintances. The incidence of SV revealed an increasing trend in both sexes during the decade, more significantly in females in 2002 and 2009. The age groups indicated the same trend, with a higher proportion of cases in adolescence. The record of co-occurrences with SV was more pronounced in the second half of the decade, namely psychological violence in 2008, neglect in 2008 and physical violence in 2009. The conclusion is that the increase in the coefficients of sexual violence and co-occurrences may indicate an improvement of the reporting system of instances in reference, as well as greater citizen participation through the Dial 100 complaint hotline. The indicators help to prevent and control violence against children.

Notification of juvenile violence in Emergency Services of the Brazilian Unified Health System in Feira de Santana, Bahia, Brazil

OBJECTIVE

To analyze the performance of professionals in the Emergency Units for the notification of cases of violence against children, considering sociodemographic characteristics, professional category and difficulties.

METHODS

Cross-sectional study with a simple random sample (n=200), selected from the universe of professionals (n=523) of these Emergency Units in Feira de Santana, Bahia, Brazil, from a regional general hospital and six polyclinics. Bivariate analyses and measures of association were performed to determine statistical significance.

RESULTS

Most professionals were female (82.5%), aged between 20 and 40 years old (75.5%), being nursing technicians (52.5%) and nurses (22.5%), 69.0% with a temporary employment contract. The notification was recorded by 69.5%, of them, and 60.0% asked for the opinion of another professional; 54.0% talked with the family and 42.9% reported to the Accident and Violence Surveillance System (VIVA). Statistical significance was observed in the nursing technicians category for the notification to sectors of reference, with a 95% confidence interval (95%CI) 1.28 - 2.09; and VIVA (95%CI 1.06 - 7.40). In the medical category, the significant result was not requesting the opinion of another professional (95%CI 1.02 - 3.51); not being afraid of judicial involvement (95%CI 1.19 - 4.06) and being trained in the violence matter (95%CI 1.21 - 5.00). The main difficulties cited were family omission (91.5%), fear of judicial involvement (63.5%) and lack of training (47.0%).

CONCLUSION

Most cases of violence seen at the Emergency Units were notified, however, less than 50% of professionals did not notify VIVA, pointing the need for institutional investment in technical support and ongoing training. Actions addressed to notification strengthen institutions and make the sector responsible for victim care and protection.

Nutritional status of institutionalized elderly Brazilians: a study with the Mini Nutritional Assessment

OBJECTIVE

To assess the nutritional status of elderly living in nursing homes in the city of Salvador, Brazil and associated factors.

METHODS

Cross-sectional study performed with 359 individuals of both sexes, ages equal or over 60 years old, located in Nursing Homes in the urban area of the city of Salvador, Bahia, Brazil.

RESULTS

Regarding nutritional status according to Mini Nutritional Assessment (MNA), 66.3% of the evaluated elderly were malnourished and at risk of malnutrition. When comparing sexes, it has been observed that among men the prevalence of this condition (76.6%) was higher than in women (62.4%). It has been observed, as a result of the multivariate analysis, that only the variable functional capacity for Activities of Daily Living (ADL) was statistically significant. There was moderate correlation between MNA and Mini-Mental State Examination (r=0.454; p<0.0001), as well as between MNA and the ADL scale (r=0.569; p<0.0001). There was weak negative correlation between MNA total score and age (r=0.159; p=0.002).

CONCLUSION

Malnutrition and malnutrition risk were conditions of remarkable importance, with almost two-thirds of the elderly in this situation. ADL functional capacity must be monitored given their close relationship with the nutritional status of the elderly. An interdisciplinary approach in the context of institutionalization is needed due to the association between nutritional status and variables of different dimensions.

Baixo peso ao nascer em adolescentes e adultas jovens na Região Nordeste do Brasil

Objetivos: avaliar a associação entre as características sociodemográficas, do pré-natal e do parto de mães adolescentes e adultas jovens com o baixo peso ao nascer, em capitais e outros municípios da Região Nordeste do Brasil, no período de 2011 e 2012. Métodos: estudo transversal, de base hospitalar e nível regional, realizado em 2011 e 2012. As informações foram obtidas por meio de entrevista com a puérpera no pós-parto imediato e coletados dados dos prontuários maternos e dos recém-nascidos. Um modelo teórico conceitual foi estabelecido com três níveis de hierarquia e a variável dependente foi o baixo peso ao nascer (BPN). Resultados: do total de 3009 puérperas entrevistadas, 9,7% apresentaram conceptos com baixo peso. As puérperas que realizaram menos que seis consultas no pré-natal apresentaram uma chance 1,7 vezes maior de ter RN com baixo peso; ser primigesta aumentou a chance da ocorrência do BPN em 1,5 vezes; assim como a prematuridade que representou o principal fator de exposição, elevando em 21 vezes a chance desse desfecho. Conclusões: o estudo demonstrou alta frequência de baixo peso ao nascer entre mães adolescentes e adultas jovens, tendo como principais fatores associados o número insuficiente de consultas pré-natal, primigestação e prematuridade.

Os resultados sugerem a importância de investimentos em políticas e programas de prevenção e redução de danos, buscando ampliar a cobertura no atendimento e aprimoramento do Sistema de Informação e levantamento desses indicadores.

Fatores associados à infecção pelo HIV/AIDS entre adolescentes e adultos jovens matriculados em Centro de Testagem e Aconselhamento no Estado da Bahia, Brasil

O estudo procura investigar fatores associados à infecção pelo HIV entre adolescentes e adultos jovens, registrados no Centro de Testagem e Aconselhamento/CTA de Feira de Santana, Bahia. Estudo analítico com delineamento transversal, utilizando dados do Sistema de Informação do CTA (SI-CTA) no período de 2007 a 2011. Foram processadas informações de 3.768 indivíduos, sendo verificada a diferença de proporções, com Qui-quadrado de Pearson e análise estratificada, através da Razão de Prevalência/RP, com Intervalos de Confiança de 95%, considerando como desfecho o status sorológico. No período estudado, 73 jovens estavam infectados pelo HIV (1,94%). Na população feminina, foram identificadas associações, estatisticamente significantes, para soropositividade e consumo de drogas, consumo de bebidas alcoólicas e outras drogas; estar casada ou em união estável. No sexo masculino, associaram-se com a soropositividade o consumo de outras drogas e orientação homossexual/bissexual. Em ambos os sexos, na categoria com parceiro estável, a soropositividade mostrou associação com companheiro usuário de drogas e/ou portador de DST e/ou HIV. Esses achados sinalizam a necessidade de medidas eficazes no controle e prevenção da infecção pelo HIV, entre jovens.

Gravidez na adolescência: análise de fatores de risco para baixo peso, prematuridade e cesariana

O objetivo do estudo foi analisar possíveis associações entre a faixa etária materna até 16 anos, com o peso e a idade gestacional do recém-nascido, assim como a ocorrência de cesaria na. Estudo transversal com dados das Declarações de Nascidos Vivos/DN obtidos através do Sistema Nacional de Nascidos Vivos/SINASC, de Feira de Santana, Bahia, Brasil, no período 2006 a 2012. Nas análises, utilizou-se regressão logística, em razão de odds (OR) e intervalo de confiança de 95 %, medindo a força de associação entre variáveis, ajustadas aos fatores de confundimento. Os Recém Nascidos de baixo peso e de peso insuficiente mostraram associação significante com a faixa etária materna (< 16 anos); e interação estatística do pré-natal inadequado e cesariana; em gestantes adolescentes com idade abaixo de 16 anos, a cesariana mostrou associação significante com estado civil solteira (OR 1,24), pré-natal inadequado (OR 1,58) e Recém Nascidos de baixo peso (OR 1,34). Os dados sugerem que múltiplos fatores podem interferir no tipo de parto e resultado gestacional de adolescentes em idade muito precoce, apontando a importância de investimentos em políticas e ações direcionadas a esse grupo, considerado de alta vulnerabilidade aos agravos gestacionais e perinatais.

Iniciação e consumo de substâncias psicoativas entre adolescentes e adultos jovens de Centro de Atenção Psicossocial Antidrogas/CAPS-AD

O estudo tem como objetivo caracterizar a iniciação e o padrão de consumo de substâncias psicoativas, entre adolescentes e adultos jovens matriculados em Centro de Atenção Psicossocial Álcool e Drogas - CAPS AD. Foram utilizados os registros dos atendimentos, sendo o padrão de consumo classificado segundo a OMS: uso pouco frequente (uso na vida, no ano ou no mês até cinco dias); uso frequente (de seis até 19 vezes nos últimos 30 dias); uso pesado (> 20 vezes nos últimos 30 dias); na comparação das faixas etárias utilizou-se teste de proporções e para análise das associações, calculou-se prevalência/P e razão de prevalência/RP, com significância de 5% e intervalo de confiança 95%. No total de adolescentes e jovens atendidos entre 2003 e 2008 (475), a maioria foi masculina, solteira, com baixa escolaridade, coabitando com pais e sintomas psíquicos. Constatou-se significância estatística para idade de iniciação ao consumo: adolescentes, em relação aos jovens iniciaram mais precocemente (< 14 anos): o consumo de tabaco; maconha, cocaína; crack e outras SPA. Entre adolescentes, verificou-se resultados significantes para consumo menos frequente de tabaco; mais frequente de álcool; e consumo pesado de maconha. Esses achados podem contribuir para programas preventivos e terapêuticos do CAPS-AD.
