This study aims to investigate the relationship between social determinants of health (SDH), incidence, and mortality to verify which sociodemographic factors, symptoms, and comorbidities predict clinical management; second, this study aims to conduct a survival analysis of individuals with COVID-19 in the Xingu Health Region. Consequently, this study adopted an ecological framework, employing secondary data of COVID-19-positive individuals from the Xingu Health Region, Pará State, Brazil. The data were obtained through the database of the State of Pará Public Health Secretary (SESPA) for the period from March 2020 to March 2021.

  • The study investigated the relationship between sociodemographic and clinical factors in live births with spinal dysraphism in Brazil from 1999 to 2019.
  • Notable findings included an overall increase in spinal dysraphism cases, with high incidence in mothers born after 1980, older than 30, and with higher education levels.
  • The absence of prenatal care was linked to higher rates of spinal dysraphism, particularly among live births weighing less than 3000g and occurring from double pregnancies.*

Introduction: Our study presents a method to generate a novel detection coefficient for the association between leprosy and pregnancy (DCLP). Methods The DCLP was calculated for women from the State of Pará (2007-2009), Brazil. Data were ordered, divided into five equal parts (corresponding to the P20, P40, P60, and P80 percentiles), and classified as low, medium, high, very high, or hyperendemic.
