Rh disease in Mexico: evaluating regional and institutional differences in treatment availability and disease management.

Background: Rh disease occurs following maternal alloimmunization, which can develop due to RhD blood group antigen incompatibility between a mother and her fetus. Despite developing robust clinical protocols for effective immunoprophylaxis over the last 50+ years, a significant global burden of Rh disease still exists, particularly in low/middle-income countries such as Mexico.

Materials And Methods: This study examined disparities in the allocation of maternal and child health resources, as well as clinical knowledge regarding Rh disease, to gain insight into why Rh disease remains prevalent in Mexico.

[Soy beverages and women's health: evidence review and experts opinion].

Soy drinks are an increasingly consumed option within the Western diet. However, there are concerns about potential endocrine disruptor effects and possible impact on women's reproductive health. This review evaluates scientific documents in gynecology and obstetrics under an evidence-based medicine approach.

[Non-caloric sweeteners in women of reproductive age - A consensus document].

Non-nutritive sweeteners (NNS) are food additives that have been used as a possible tool to reduce energy and sugar intake. There is a scientific debate around the real benefits of their use. NNS are substances widely evaluated in the scientific literature.

Changes in circulating concentrations of soluble fms-like tyrosine kinase-1 and placental growth factor measured by automated electrochemiluminescence immunoassays methods are predictors of preeclampsia.

Objective: Preeclampsia is characterized by an imbalance in angiogenic factors such as soluble fms-like tyrosine kinase-1 (sFlt-1) and placental growth factor (PlGF). We herein assessed whether these factors measured by a newly developed automated electrochemiluminescence immunoassay are associated with risk to develop preeclampsia.

Methods: We performed a nested case-control study within a cohort of 230 women with singleton pregnancies.

[Pregnancy in patients with renal transplantation: maternal and fetal morbidity].

Background: Preeclampsia is a multisystemic syndrome with unknown etiology and characterized by abnormal vascular placentation response. Patients with renal transplantation restore them fertility 10 months after the intervention.

Objective: To evaluate incidence of preeclampsia and maternal-perinatal outcome in patients with renal transplantation.

[Antiphospholipid syndrome and pregnancy].

Objective: To assess the maternal and perinatal outcome of patients with antiphospholipid syndrome in pregnancy.

Patients And Method: A descriptive and retrospective analysis of patients with antiphospholipid syndrome in pregnancy was made from January 2000 to June 2005.

Results: We analyzed 35 patients.

Vaginal matrix metalloproteinase levels in pregnant women with bacterial vaginosis.

Objective: To compare matrix metalloproteinase (MMP)-8 and MMP-9 levels in the vaginal secretions of pregnant women with or without asymptomatic bacterial vaginosis (BV).

Methods: In this study, vaginal levels and molecular forms of MMP-8 and MMP-9 were studied in 36 pregnant women between 28 and 34 weeks of gestation with asymptomatic BV and 41 pregnant women, matched for gestational age, without BV.

Results: Vaginal MMP-8 concentrations were significantly higher (P = .

[Usefulness of fetal biophysical profile in preterm rupture of membranes with treatment].

Objective: To evaluate the usefulness of the fetal biophysical profile as a predictor of early neonatal infection in patients with preterm rupture of membranes in conservative management.

Patients And Methods: This is a validation study of a diagnostic test. Between November, 2001 and August, 2003, 75 patients with 27 to 33 weeks of gestation and preterm rupture of membranes in conservative management were studied.

[Economical impact of preterm delivery management based on fetal fibronectin results].

Background: Preterm labor continues to be the first cause (after congenital malformations) of morbidity and mortality during the perinatal period. One of the markers showing the highest sensitivity to predict preterm labor seems to be fetal fibronectin (fFN) determined in the cervicovaginal secretion.

Objectives: To identify patients at risk of preterm labor based on the presence of fFN in cervicovaginal secretions and to analyze the cost-benefit of medical attention and hospital stay depending on the fFN results.
