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

Trends, seasonality and effect of ambient temperature on preterm delivery
TL;DR: Spontaneous PTD is more common during the summer and its rate is declining steadily over the past decades, and increased outdoor temperature has a significant effect on the incidence of spontaneous, but not induced, PTD.

Is early breast milk fortification more effective in preterm infants?: a clinical trial.
TL;DR: It is suggested that early fortification from the first feeding in neonates with exclusive breast feeding did not improve growth in the first 4 weeks in preterm neonates in comparison with late fortification; so early fortify may not be cost effective.

Improving the knowledge of pregnant women using a pre-eclampsia app: A controlled before and after study.
TL;DR: In this article, the authors investigated the effect of a pre-eclampsia mobile application on the knowledge of pregnant women and found that the use of a mobile-based educational application improves the knowledge among pregnant women.

TL;DR: To compare postural control at 4 years' corrected age in very preterm children (VPT) with term‐born (>37wks gestational age) comparison participants, a large number of participants were recruited for the VPT study.

TL;DR: The risk for PTB in women with different pre-pregnancy BMI categories differs according to ethnicity, and the role of ethnicity as a risk modifier in BMI-associated PTB is assessed.

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.
