Factors associated with cesarean delivery in adult nulliparous women

The aim of this study was to analyze the sociodemographic factors associated with cesarean section in adult women with conditions favorable for normal delivery and to identify the groups most likely to undergo this surgery inthe state of Santa Catarina (SC). A case control study with microdata from the Sistema de Informação de Nascidos Vivos on 7,065 women for 2016 in SC. A relationship between cesarean section and sociodemographic variables was analyzed by logistic regression where we calculated the Adjusted Odds Ratio (AOR), confidence interval and p-value. The probability of cesarean section for each group of women (called "interaction") was also calculated. Among women with more favorable conditions for normal childbirth, the prevalence of cesarean section was 41.1%. Lower chance of cesarean section was found for women without partners (AOR: 0.79 [0.71-0.87]), up to 8 years of schooling (AOR: 0.56 [0.47-0.66]), with up to 2 prenatal visits (AOR: 0.46 [0.23-0.90]). The most likely group of women (51.4% [49.3-53.4]) to undergo cesarean section are women who perform 7 to 15 prenatal visits and have 12 or more years of schooling. A cesarean section occurs with women who have greater access to education and prenatal care and those who have partners, even though the aspects favor normal childbirth, suggesting that this does not seem to be a decision only by women.

Presence of teleconsultation equipment in the health centers ranged from 1.2% in large northern municipalities to 26.7% in small southern municipalities. Established work process ranged from 10.7% in small northern municipalities to 39.5% in large southern municipalities. Compared to the South, medium-sized municipalities in the North (OR=0.14 - 95%CI 0.11;0.17) and Northeast (OR=0.21 - 95%CI 0.18;0.25) regions were less likely to have the necessary equipment. Conclusion: Significant regional inequalities call for investments in Digital Health.

Adoecimento por coqueluche e número de doses administradas de vacinas Pertussis: estudo de caso-controle / Pertussis and number of doses of vaccine administered: a case control study

Objetivo: estimar as chances de adoecimento por coqueluche segundo número de doses de vacinas Pertussis administradas e idade, no Brasil. Métodos: estudo de caso-controle utilizando dados do Sistema de Informação de Agravos de Notificação (Sinan) no período 2007-2011; considerou-se como casos aqueles notificados com coqueluche confirmada, e como controles, aqueles descartados; foram calculadas as odds ratio (OR) e respectivos intervalos de confiança de 95 por cento (IC95 por cento). Resultados: foram incluídos 5.389 casos e 10.689 controles; entre 7-12 meses de idade, a chance de adoecimento foi maior com 1 dose administrada [OR:2,1(IC95 por cento:1,3-3,4)], comparativamente às 3 doses esperadas; entre 1-3 anos, essa chance foi maior sem reforço vacinal [OR 1 dose: 2,4(IC95 por cento:1,6-3,8); OR 2 doses:3,6(IC95 por cento:2,2-6,1); OR 3 doses:1,6(IC95 por cento:1,3-2,2); OR Ø dose:2,8(IC95 por cento:1,7-4,8)], quando este era esperado; entre 7-15 anos, foi maior com 1 reforço [OR:1,6(IC95 por cento:1,2-2,3)], quando 2 eram esperados. Conclusão: o esquema vacinal incompleto aumenta as chances de adoecimento por coqueluche em todas as idades estudadas.

Objective: estimate the likelihood of pertussis according to number of vaccine doses received and age. Methods: Case-control study using 2007-2011 SINAN data. "Cases" were considered to be confirmed reported pertussis cases. "Controls" were the discarded cases. Results: 5,389 cases and 10,689 controls were included. In those aged 7-12 months, cases were twice as likely [OR:2.1 (95 per cent CI: 1.3-3.4)] when only 1 instead of 3 doses had been administered. In 1-3 year--olds, likelihood was greater in those not having boosters (1 booster expected) [OR 1 dose: 2.4 (95 per cent CI:1.6-3.8); OR 2 doses: 3.6 (95 per cent CI: 2.2-6.1); OR 3 doses: 1.6 (95 per cent CI:1.3-2.2); OR Ø dose: 2.8 (95 per cent CI:1.7-4.8)]. In 7-15 year-olds, cases were 60 per cent more likely in those having had 1 booster instead of 2 [OR:1.6 (95 per cent CI:1.2-2.3)]. Conclusion: incomplete immunization increases likelihood of contracting pertussis in all age groups studied, mainly 7-15 years.

Risk factors associated with hantavirosis fatality: a regional analysis from a case-control study in Brazil

Introduction: In Brazil, hantavirus cardiopulmonary syndrome (HCPS) has a high lethality rate that varies by region. This study aimed to identify the risk factors associated with fatal hantavirosis. Methods: This study was a case-control study that included all laboratory confirmed cases of hantavirosis. The cases were stratified by the different Brazilian regions using data from the Notifiable Diseases Information System. “Cases” were patients who progressed to death, whereas “controls” were patients who were cured. The odds ratio (OR) and the adjusted OR were calculated. Results: Overall, 158 cases and 281 controls were included in this study. In the Midwest region, the cases were 60% less likely to present with flank pain, and the time between the beginning of symptoms and death was shorter than the time between the beginning of symptoms and a cure. In the Southeast region, the cases were 60% less likely to present with thrombocytopenia or reside in rural areas compared to those who progressed to a cure. Additionally, the cases sought medical assistance, notification and investigation more quickly than the controls. In the Southern region, the cases that died were 70% less likely to be male compared to the controls. Conclusions: HCPS manifests with nonspecific symptoms, and there are few published studies related to the condition, so determining a patient's therapeutic strategy is difficult. This study presents findings from different Brazilian regions and highlights the need for further investigations to improve comprehension about regional risk factors associated with hantavirosis and to reduce morbimortality. .
