Intrauterine growth restriction and prematurity determine low birth weight. The combination of the three conditions results in different neonatal phenotypes that interfere with child survival. Neonatal prevalence, survival and mortality were estimated according to neonatal phenotypes in the cohort of live births in 2021 in the state of Rio de Janeiro, Brazil.

[Avoidability of fetal deaths: reflections on the Brazilian List of Avoidable Causes of Deaths through interventions by the Brazilian Unified National Health System].

Although the Brazilian List of Avoidable Causes of Deaths (LBE in Portuguese), in its version for children under 5 years of age (LBE < 5), does not include stillbirths, some studies have used the list with or without adaptations. We present a proposal for adaptation of the LBE for stillbirths (LBE-OF in Portuguese) and the results of its application to stillbirths in the State of Rio de Janeiro, Brazil, in 2018, compared to the results with LBE < 5. We reviewed the categories from the 10th revision of the International Classification of Diseases (ICD-10) in the LBE < 5 and reassigned them in the avoidability groups, according to time of death in relation to delivery and the causes consistent with stillbirths.

Methods this was a descriptive case series study of perinatal deaths using primary data from the Mortality Information System; the BAL was applied, with adaptations (codes P20.9 and P70-74) and, in addition in Rio de Janeiro the Extended Wigglesworth (EW) Classification was also used.

Life-threatening conditions at birth: an analysis of causes of death and survival estimate for under-five children in live birth cohorts.

Despite the reduction in under-five mortality, the causes are still mostly avoidable, and survival may be compromised by life-threatening conditions at birth.

This was a retrospective cohort study of live birth in the city of Rio de Janeiro, Brazil (2012-2016).

[Validity of information on birth weight for studies based on fetal programming].

Birth weight is essential information in fetal programming studies and is generally obtained retrospectively. In Brazil's Information System on Live Births (SINASC), birth weight is valid information but is not always accessible. The study aimed to establish an algorithm for the selection of the most reliable data source for birth weight in the absence of information in the SINASC database.

We aimed to evaluate factors associated with cases of neonatal near miss and neonatal deaths at six public maternity hospitals in São Paulo and Rio de Janeiro States, Brazil, in 2011. A prospective hospital-based birth cohort investigated these outcomes among live births with life-threatening conditions. Associations were tested using multinomial logistic regression models with hierarchical levels.

Use of primary diagnosis during hospitalization in the Unified Health System (Sistema Único de Saúde) to qualify information regarding the underlying cause of natural deaths among the elderly.

Introduction:: Ill-defined causes of death are common among the elderly owing to the high frequency of comorbidities and, consequently, to the difficulty in defining the underlying cause of death.

Objective:: To analyze the validity and reliability of the "primary diagnosis" in hospitalization to recover the information on the underlying cause of death in natural deaths among the elderly whose deaths were originally assigned to "ill-defined cause" in their Death Certificate. The hospitalizations occurred in the state of Rio de Janeiro, in 2006.

Methods:: DC with mention of pulmonary sepsis was identified, regardless of the underlying cause of death. Medical records related to the certificates with reference to "pulmonary sepsis" were reviewed and physicians were interviewed to measure the association between pulmonary sepsis and pneumonia.

Strategy for the selection and investigation of deaths of women of reproductive age.

Introduction: Different approaches have been developed in order to deal with maternal mortality. In 2008 the Brazilian Ministry of Health made mandatory the investigation of all deaths of women of reproductive age. So far, completeness of investigation has not been thoroughly accomplished in the State of Rio de Janeiro (RJ) due to the constrained capacity of public health services to investigate the large number of eligible deaths.

[Quality of mortality information in a diabetes cohort--State of Rio de Janeiro, 2000 to 2003].

Objective: The aim of this study was to demonstrate the quality of the National Mortality Information System (SIM) in a special cohort of inpatients submitted to lower limb amputation (LLA) as a result of diabetes mellitus (DM), and compare the mortality pattern by causes for the cohort and for the population base of the State of Rio de Janeiro, from 2000 to 2003.
