Serum Folate, Red Blood Cell Folate, and Zinc Serum Levels Are Related with Gestational Weight Gain and Offspring's Birth-Weight of Adolescent Mothers.

Background: Gestational weight gain below or above the Institute of Medicine recommendations has been associated with adverse perinatal and neonatal outcomes. Very few studies have evaluated the association between serum and red blood cell folate concentrations and gestational weight gain in adolescents. Additionally, zinc deficiency during pregnancy has been associated with impaired immunity, prolonged labor, preterm and post-term birth, intrauterine growth restriction, low birth weight, and pregnancy-induced hypertension.

Are Overweight and Obesity Risk Factors for Developing Metabolic Syndrome or Hypertension after a Preeclamptic Event?

Objective: To identify the determinants and risks associated with developing hypertension and metabolic syndrome in the first year postpartum in women who experienced preeclampsia.

Methods: A cohort study was conducted, involving women who had experienced preeclampsia (PE) recently. The control group was women with the same characteristics but a healthy pregnancy.

Association of Diet, Body Mass Index, and Lifestyle on the Gastrointestinal Health Risk in a Sample of Adults.

Gastrointestinal functional disorders are characterized by abnormalities in motility with visceral hypersensitivity, representing a global public health problem. We aimed to determine whether eating habits, lifestyle characteristics, and body mass index (BMI) are associated with gastrointestinal health risk. The Gastrointestinal Health (GIH) test of the World Gastroenterology Organization (WGO) and the Roma IV criteria were applied.

Association of Pregestational BMI and Gestational Weight Gain with Maternal and Neonatal Outcomes in Adolescents and Adults from Mexico City.

During pregnancy, adolescents experience physiological changes different from adults because they have not concluded their physical growth. Therefore, maternal and neonatal outcomes may not be the same. This paper aimed to analyze the association between pregestational BMI (pBMI) and gestational weight gain (GWG) with maternal and neonatal outcomes in adolescent and adult pregnant women.

Factors Associated With Weight, Length, and BMI Change in Adolescents' Offspring in Their First Year of Life.

Young maternal age is associated with negative outcomes at birth and with offspring's growth. In low- and middle-income countries, adolescents' offspring growth little has been studied. To determine the association of maternal sociodemographic characteristics with weight, length, and BMI change in adolescents' offspring in their first year of life.

Neonatal adiposity may increase plasmatic cytokines.

Maternal health and nutritional status before and during gestation may affect neonates' immune system and energy balance as they develop. The objective of this study was to associate certain clinical markers of maternal adiposity (body mass index and gestational weight gain) and neonatal adiposity (birth weight, abdominal circumference, and waist/height index) with the levels of pro- and anti-inflammatory cytokines in umbilical cord blood at birth: IL-1β, IL-1Rα, IL-4, IL-6, IL-10, IFN-γ, and TNF-α. An exploratory cross-sectional study was conducted with a convenience sample of women from one hospital recruited shortly before giving birth through scheduled cesarean section.

Associations between prenatal serum levels of leptin, IGF-I, and estradiol and adolescent mothers' height gain during and after pregnancy.

Mexico is within the top three Latin American countries with the highest proportion of adolescent pregnancies while being in the lowest ten Latin American countries in terms of height. It is still unclear how much growth in adolescence is affected by pregnancy; therefore, this study was designed to study the association between prenatal serum concentrations of leptin, IGF-I, and estradiol and the increase in the height of a group of pregnant adolescents between the 28th week of gestation to one year postpartum. We conducted a cohort study from 2009 to 2017 in pregnant adolescents in their third trimester of pregnancy receiving prenatal care at Mexico's National Institute of Perinatology.

Dietary Knowledge and Myths Vary by Age and Years of Schooling in Pregnant Mexico City Residents.

Pregnancy is a stage in a woman's life when she is more open to receiving health advice, especially related to diet. However, women are often caught between receiving scientifically unfounded myths and concrete empirical knowledge. Culturally perpetuated myths may be acted upon more than knowledge, but research on these concepts, especially in the Americas, is scarce.

Oxidative stress biomarkers and their relationship with cytokine concentrations in overweight/obese pregnant women and their neonates.

Background: Oxidative damage present in obese/overweight mothers may lead to further oxidative stress conditions or inflammation in maternal and cord blood samples. Thirty-four pregnant women/newborn pairs were included in this study to assess the presence of oxidative stress biomarkers and their relationship with serum cytokine concentrations. Oxidative stress biomarkers and antioxidant enzymes were compared between the mother/offspring pairs.

Relationship between Irisin Concentration and Serum Cytokines in Mother and Newborn.

Introduction: Irisin is considered to be a myokine and adipokine that may also participate in reproductive functions, as it increases significantly throughout pregnancy. However, the regulation of circulating irisin and its relationship with other cytokines has not been assessed thus far in pregnant women and their offspring.

Objective: The aim of this study was to evaluate differences in irisin and cytokine concentrations between women at the end of pregnancy and their offspring, as well as the relationship between maternal and newborn irisin and maternal and newborn biomarkers.

Reporting detection of Chlamydia trachomatis DNA in tissues of neonatal death cases.

Objective: to determine whether C. trachomatis was present in neonates with infection, but without an isolated pathogen, who died during the first week of life.

Methods: early neonatal death cases whose causes of death had been previously adjudicated by the institutional mortality committee were randomly selected.

[Anti-C. trachomatis IgG antibodies levels in serum to identify infertility caused by tubal damage].

Objective: To identify the serologic titers of anti-Chlamydia trachomatis IgG (Ab) antibodies that could be used to differentiate tubal damage infertility from other causes of subfertility in a group of Mexican women.

Material And Methods: This was a prospective, longitudinal and analytical study of 147 women selected in a non-random way. The women were classified into three sub-groups: 1) infertile women with tubal occlusion detected by laparoscopy (n = 58); 2) infertile women with alternative causes of subfertility (n = 50), and 3) fertile women for the control group (n = 39).

[High prevalence of group B Streptococcus colonization in Mexican pregnant women].

Objective: To determine the prevalence of group B Streptococcus (GBS) colonization in two anatomical sites in Mexican women of childbearing age, as well as the associated risk factors.

Patients And Method: A retrospective cohort analysis was made with two groups of women between 14 and 44 years old. We formed two groups of 72 women; one had a recent positive group B Streptococcus culture and the other, paired by age and culture date, had a negative culture of the same bacterium.

[Maternal and congenital syphilis in two Mexican hospitals: evaluation of a rapid diagnostic test].

Objective: To estimate the prevalence of maternal and neonatal syphilis, to assess the usefulness of a rapid treponemic diagnostic test, and to evaluate the frequency of screening for syphilis during prenatal care in Mexican women.

Material And Methods: This was a cross-sectional study that included 1,322 women interviewed in two hospitals (Hospital General in Cuernavaca, Morelos, and Hospital de la Mujer in Mexico City). Women answered a questionnaire on reproductive background, exposure to sexually transmitted infections and prenatal care.
