[Secular trend in infant deaths by congenital malformations in Argentina (1980-2018)].

Introduction: Congenital malformations (CM) represent the second cause of infant death in Argentina.

Objective: To analyze the secular trend (1980-2018) of infant deaths due to CM at the regional and provincial level.

Material And Methods: The data come from the DEIS (Ministry of Health) and include the absolute number of deaths and live births and deaths by CM coded according to ICD-10 (Codes Q00-Q99).

Revisiting the Neuropathology of Sudden Infant Death Syndrome (SIDS).

Sudden infant death syndrome (SIDS) is one of the leading causes of infant mortality in the United States (US). The extent to which SIDS manifests with an underlying neuropathological mechanism is highly controversial. SIDS correlates with markers of poor prenatal and postnatal care, generally rooted in the lack of access and quality of healthcare endemic to select racial and ethnic groups, and thus can be viewed in the context of health disparities.

Microcephaly infant mortality in Brazil before zika outbreak.

Introduction: We present temporal and spatial variation of deaths from microcephaly in children under 1 year of age is analyzed at regional, state, and municipal level in the pre-Zika period in Brazil.

Materials And Methods: Data on births and deaths of infants with microcephaly was obtained from DATASUS from 1996 to 2013. Infant mortality rate from microcephaly (IMR-M) was estimated at Region, Federative Unit (UF), and Municipality level.

Epidemiology of sudden unexpected death in infancy in Argentina: secular trend and spatial variation.

Introduction: Infant mortality comprises deaths among infants younger than one year old. The proportion of sudden unexpected death in infancy (SUDI) varies by country and based on the cause of death.

Objective: To describe the spatial and temporal variation of SUDI in Argentina between 1991 and 2014 according to the International Classification of Diseases, tenth revision.

Relationship between infant mortality and altitude in the Northwest region of Argentina.

Introduction: Given its location on the Andes, the Northwest region of Argentina is geographically, socioeconomically, culturally, and biologically heterogeneous, and this is reflected on an infant mortality rate (IMR) that is higher than in any other Argentine region.

Objetive: To estimate IMR, neonatal mortality rate (NMR), and post-neonatal mortality rate (PNMR), and to analyze their spatial and temporal variations using secular trends and the relative risk based on altitudinal zones.

Population And Method: This was a retrospective, descriptive, correlational study based on birth and death data recorded in the Northwest region of Argentina (1998-2010); IMR, NMR, PNMR, secular trends, and the relative risk of death were calculated by district and altitudinal zone (districts at < 2000 meters above sea level, lowlands; at > 2000 meters above sea level, highlands) by means of a cluster analysis.
