[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).

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.

Infant mortality due to congenital malformations in the Autonomous City of Buenos Aires (1998-2015): Spatial, temporal analysis and relation to the socioeconomic status.

Introduction: In Argentina, congenital malformations (CM) account for the second cause of death among infants younger than 1 year.

Objective: To analyze spatial and temporal variation in infant mortality due to CM in the Autonomous City of Buenos Aires and its relation to a socioeconomic development indicator.

Materials And Methods: Births and deaths among infants younger than 1 year were coded using the International Classification of Diseases (ICD-10); data were provided by the Ministry of Health.

[Spatial and temporal analysis of infant mortality from microcephaly in Argentina (1998-2012)].

Due to the increase in cases of microcephaly caused by Zika virus in Brazil, the Ministry of Health of Argentina recommends increasing surveillance of this malformation. In order to deepen the knowledge of the epidemiological behavior of microcephaly in the country, infant mortality by microcephaly is analyzed between 1998 and 2012. The data come from the Direction of Statistics and Health Information (DEIS).

[Infant mortality from congenital malformations in Chile: temporal and spatial analysis, 1997-2011].

Objective: To analyze the spatial and temporal distribution (1997-2011) of infant mortality resulting from congenital malformations (CM) in Chile.

Methods: Data on births and deaths among infants aged less than one year using ICD-10 coding were obtained from the National Statistics Institute. The percentage of deaths from CM (PD-CM) and the infant mortality rate from CM (IMR-CM) during three different periods (1997-2001, 2002-2009, 2007-2011) were estimated for Chile's administrative and natural regions (Norte Grande, Norte Chico, Central, Austral, and Sur), broken down by systems (nervous, cardiovascular, digestive, genitourinary, musculoskeletal, and chromosomal abnormalities) and by 28 specific malformations.

[Infant mortality due to congenital malformations and socioeconomic status: the case of Argentina].

Objective: Compare the infant mortality rate due to congenital malformations ( IMRCM) and the percentage of deaths due to congenital malformations (%DCM) with sociodemographic and economic characteristics in Argentina.

Methods: The Argentine study population resided in 511 departments of 23 provinces, grouped into five geographic regions (Northwest, Northeast, Central, Cuyo, and Patagonia). The analyzed variables were the IMRCM and the %DCM calculated on the basis of births and deaths during 2002-2006 period.

[Prevalence of malnutrition in institutionalized intellectually disabled patients].

As patients with intellectual and developmental disability (ID) may be more exposed to unfavorable factors, they are at higher risk of suffering nutritional alterations. Our objective was to determine prevalence of malnutrition in institutionalized patients with ID. An evaluation of the nutritional status through determination of transversal anthropometric parameters of weight (kg) and height (cm) was made on 614 individuals (352 men and 262 women) institutionalized at Colonia Nacional Montes de Oca, Buenos Aires Province, Argentina.

Isonymy structure of Buenos Aires city.

The isonymy structure of Buenos Aires was studied based on its surname frequency. Information on 2,552,359 voters of the 28 Buenos Aires districts was used to estimate Lasker's coefficient of relationship by isonymy (R(i)), surname diversity according to Fisher's alpha, the coefficient of consanguinity resulting from random isonymy (F), and Nei's, Lasker's and the Euclidean isonymy distances. These distances were correlated with geographic distances, which were calculated by assigning an arbitrary point to each district and measuring distances on a map of the city.
