TLDR
Developing countries, especially those in Africa and southern Asia, incur the highest burden in terms of absolute numbers, although a high rate is also observed in North America.Abstract:
Resumen Incidencia mundial de parto prematuro: revision sistematica de la morbilidad y mortalidad maternas Objetivo Analizar las tasas de prematuridad a nivel mundial para evaluar la incidencia de este problema de salud publica, determinar la distribucion regional de los partos prematuros y profundizar en el conocimiento de las actuales estrategias de evaluacion.Metodos Los datos utilizados sobre las tasas de prematuridad a nivel mundial se extrajeron a lo largo de una revision sistematica anterior de datos publicados e ineditos sobre la mortalidad y morbilidad maternas notificados entre 1997 y 2002. Esos datos se complementaron mediante una busqueda que abarco el periodo 2003–2007. Las tasas de prematuridad de los paises sin datos se estimaron mediante modelos de regresion multiple especificos para cada region.Resultados Estimamos que en 2005 se registraron 12,9 millones de partos prematuros, lo que representa el 9,6% de todos los nacimientos a nivel mundial. Aproximadamente 11 millones (85%) de ellos se concentraron en Africa y Asia, mientras que en Europa y America del Norte (excluido Mexico) se registraron 0,5 millones en cada caso, y en America Latina y el Caribe, 0,9 millones. Las tasas mas elevadas de prematuridad se dieron en Africa y America del Norte (11,9% y 10,6% de todos los nacimientos, respectivamente), y las mas bajas en Europa (6,2%).Conclusion El parto prematuro es un problema de salud perinatal importante en todo el mundo. Los paises en desarrollo, especialmente de Africa y Asia meridional, son los que sufren la carga mas alta en terminos absolutos, pero en America del Norte tambien se observa una tasa elevada. Es necesario comprender mejor las causas de la prematuridad y obtener estimaciones mas precisas de la incidencia de ese problema en cada pais si se desea mejorar el acceso a una atencion obstetrica y neonatal eficaz.read more

Developmental delay in moderately preterm-born children with low socioeconomic status: risks multiply.
TL;DR: Low SES and moderate prematurity are separate risk factors with multiplicative effects on developmental delay and the double jeopardy of MP children with low SES needs special attention in pediatric care.

Lung consequences in adults born prematurely
TL;DR: There are a number of clinical and research priorities to maximise the quality of life and lung health in the longer term not least understanding the underlying mechanisms and optimising treatment, rather than extrapolating from other airway diseases.

Elevated blood pressure in preterm-born offspring associates with a distinct antiangiogenic state and microvascular abnormalities in adult life.

TL;DR: Preterm-born individuals exhibit an enhanced antiangiogenic state in adult life that is specifically related to elevations in blood pressure, and this association seems to be mediated through capillary rarefaction and is independent of other cardiovascular structural and functional differences in the offspring.

Maternal Dietary Patterns and Pregnancy Outcome
TL;DR: This review examined articles about the relationship between maternal dietary patterns and pregnancy outcome and found that dietary patterns may be more applicable to clinical and pregnant health interventions.

TL;DR: Identifying similar studies on biomarkers for the prediction of PTB was a very challenging task due heterogeneities in study design, sampling issues, sampling methods, assay methods, and analyses.

TL;DR: In this article, the Straight Line Case is used to fit a straight line by least squares, and the Durbin-Watson Test is used for checking the straight line fit.

Epidemiology and causes of preterm birth
TL;DR: A short cervical length and a raised cervical-vaginal fetal fibronectin concentration are the strongest predictors of spontaneous preterm birth.

TL;DR: The evidence indicating that the pathological processes implicated in the preterm parturition syndrome include: intrauterine infection/inflammation; uterine ischaemia; (3) uterine overdistension; (4) abnormal allograft reaction; (5) allergy; (6) cervical insufficiency; and (7) hormonal disorders (progesterone related and corticotrophin‐releasing factor related).

TL;DR: Over the past 20-30 years advances in perinatal care have improved outcomes for infants born after short gestations, but there is still uncertainty and incomplete recording of estimates of gestation in developed countries.
