Resultados perinatales en mujeres mexicanas con lupus eritematoso sistémico

Objetivo: Conocer la incidencia de resultados perinatales en mujeres mexicanas con embarazo único y lupus eritematoso sistémico. Materiales y métodos: Estudio de cohorte histórica en el que se incluyeron mujeres diagnosticadas con lupus eritematoso sistémico, embarazo único, control prenatal y resolución entre 2010 y 2015. Se calculó la incidencia de los siguientes resultados perinatales: nacimiento pretérmino, muerte fetal temprana, oligohidramnios, aborto, rotura prematura de membranas, hipertensión gestacional, preeclampsia, restricción del crecimiento intrauterino y defectos congénitos. Resultados: Se incluyeron 122 mujeres. Las características de la población de estudio al ingreso y resolución fueron: edad materna 26.2 ± 6 años, peso materno 63.4 ± 11.1 kg, índice de masa corporal 26 ± 3.9 kg/m2, número de gestaciones 1.9 ± 1.2, semanas de gestación al ingreso 16.6 ± 6.5, semanas de gestación a la resolución 36.1 ± 3.4, peso neonatal 2,417 ± 770 g. La incidencia de resultados perinatales adversos fue: nacimiento pretérmino 41.8%, óbito 1.6%, oligohidramnios 6.6%, aborto 5.7%, rotura prematura de membranas 9.8%, hipertensión gestacional 5.7%, preeclampsia 24.6, preeclampsia de inicio temprano 15.6%, anemia 23%, restricción del crecimiento intrauterino 14.7%, defectos congénitos 2.4% y cesárea 78.2%. Conclusiones: Las mujeres mexicanas con lupus eritematoso sistémico tienen una alta incidencia de nacimiento pretérmino, preeclampsia, anemia, preeclampsia de inicio temprano, restricción del crecimiento intrauterino y cesárea, si bien la incidencia de nacidos vivos está entre las más altas reportadas en la literatura

NEOTROPICAL ALIEN MAMMALS: a data set of occurrence and abundance of alien mammals in the Neotropics

Biological invasion is one of the main threats to native biodiversity. For a species to become invasive, it must be voluntarily or involuntarily introduced by humans into a nonnative habitat. Mammals were among first taxa to be introduced worldwide for game, meat, and labor, yet the number of species introduced in the Neotropics remains unknown. In this data set, we make available occurrence and abundance data on mammal species that (1) transposed a geographical barrier and (2) were voluntarily or involuntarily introduced by humans into the Neotropics. Our data set is composed of 73,738 historical and current georeferenced records on alien mammal species of which around 96% correspond to occurrence data on 77 species belonging to eight orders and 26 families. Data cover 26 continental countries in the Neotropics, ranging from Mexico and its frontier regions (southern Florida and coastal-central Florida in the southeast United States) to Argentina, Paraguay, Chile, and Uruguay, and the 13 countries of Caribbean islands. Our data set also includes neotropical species (e.g., Callithrix sp., Myocastor coypus, Nasua nasua) considered alien in particular areas of Neotropics. The most numerous species in terms of records are from Bos sp. (n = 37,782), Sus scrofa (n = 6,730), and Canis familiaris (n = 10,084); 17 species were represented by only one record (e.g., Syncerus caffer, Cervus timorensis, Cervus unicolor, Canis latrans). Primates have the highest number of species in the data set (n = 20 species), partly because of uncertainties regarding taxonomic identification of the genera Callithrix, which includes the species Callithrix aurita, Callithrix flaviceps, Callithrix geoffroyi, Callithrix jacchus, Callithrix kuhlii, Callithrix penicillata, and their hybrids. This unique data set will be a valuable source of information on invasion risk assessments, biodiversity redistribution and conservation-related research. There are no copyright restrictions.
