[Overestimation of the ocurrence of induced abortions in Colombia and other Latinoamerican countries].

Recently, the Guttmacher Institute estimated a number of 400,400 clandestine abortions for Colombia.

[Neoplastic effect of indomethacin in N-methyl-N-nitrosourea induced mammary carcinogenesis in female rats].

Background: High levels of prostaglandins found in many neoplastic tissues, especially in colon cancer and breast cancer, suggest a role of cyclooxygenase in the process of carcinogenesis.

Material And Methods: The aim of this study was to analyse the chemopreventive potential of non-steroidal inflammatory drug indomethacin and its combination with pineal hormone melatonin in rat mammary carcinogenesis induced by N-methyl-N-nitrosourea. Indomethacin was administered 3 times a week and melatonin 4 times a week, both substances in a concentration of 20 µg/ml of drinking water.

Women's education level, maternal health facilities, abortion legislation and maternal deaths: a natural experiment in Chile from 1957 to 2007.

Background: The aim of this study was to assess the main factors related to maternal mortality reduction in large time series available in Chile in context of the United Nations' Millennium Development Goals (MDGs).

Methods: Time series of maternal mortality ratio (MMR) from official data (National Institute of Statistics, 1957-2007) along with parallel time series of education years, income per capita, fertility rate (TFR), birth order, clean water, sanitary sewer, and delivery by skilled attendants were analysed using autoregressive models (ARIMA). Historical changes on the mortality trend including the effect of different educational and maternal health policies implemented in 1965, and legislation that prohibited abortion in 1989 were assessed utilizing segmented regression techniques.
