Sistema familiar y participación social en mujeres campesinas adultas de las comunas de Mulchén y Parral, posterior a la pandemia / Post Pandemic Family System and Social Participation Among Rural Adult Women in the Communes of Mulchén and Parral

Resumen La presente investigación, sobre el sistema familiar y participación social en mujeres campesinas adultas, tuvo por objetivo describir la participación social en el marco sistémico familiar de mujeres adultas en contexto rural. El estudio empleó metodología cualitativa, con un enfoque fenomenológico, considerando un muestreo no probabilístico de tipo intencionado a partir de cinco entrevistas semiestructuradas a mujeres adultas campesinas de las comunas de Mulchén y Parral. El análisis de datos se desarrolló con base en un análisis de contenido que refleja las dimensiones de la experiencia y observación de campo como las características del contexto más importantes. Los resultados obtenidos se visualizan a través de las categorías de sistema familiar, actividad de mujeres campesinas y participación social, elementos que dan cuenta de vínculo e intereses en común, como también roles culturales y funciones establecidas y no establecidas.

Abstract This study on family systems and social participation in rural adult women had the objective of describing social participation in the family systemic framework of adult women in a rural context. The study used a qualitative methodology, based on a phenomenological approach, considering a non-probabilistic, purposive sampling from 5 semi-structured interviews with rural adult women from the communes of Mulchén and Parral. The data analysis was carried out based on a content analysis that reflects the dimensions of the experience and field observation as the most important characteristics of the context. The results obtained are visualized through the categories of family system, rural women's activity and social participation, elements that account for common ties and interests, as well as cultural roles and established and non-established functions.

Perinatal Outcomes in Mexican Women with Untreated Mild Gestational Diabetes Mellitus Diagnosed by the International Association of Diabetes and Pregnancy Study Groups Criteria.

PURPOSE: To compare the risk of adverse perinatal outcomes (APO) between pregnant women with mild gestational diabetes mellitus (GDM) diagnosed by the International Association of Diabetes and Pregnancy Study Groups (IADPSG) criteria, on no specific treatment, versus pregnant women without GDM. PATIENTS AND METHODS: A retrospective cohort study of pregnant women referred to the Instituto Nacional de Perinatología, in Mexico City, for prenatal care and delivery. Eligibility criteria were singleton pregnancy, age >18 years, gestational age 20-28 weeks, and no history of pre-gestational diabetes. The study population was divided into two groups: Group 1, comprising women with mild GDM defined by one abnormal glucose value at the oral glucose tolerance test (OGTT) according to IADPSG criteria [fasting: 5.1-5.2 mmol/L (92-94 mg/dL) or 2h 8.5-8.56 mmol/L (153-154 mg/dL)], who did not receive specific treatment for GDM, and Group 2, comprising women without GDM, matched for maternal age and pre-gestational body mass index (BMI). Women with two or more abnormal OGTT values, pre-gestational diabetes, any chronic disease, or multiple pregnancies were excluded. RESULTS: As many as 282 women were included in each group. There were no significant differences in basal characteristics between groups. APO analysis showed that newborn weight was significantly higher in Group 1 (3042.4±499g) vs Group 2 (2910±565g) p=0.003; conversely, the incidence of large for gestational age (LGA) and macrosomic neonates was similar in both groups (6 vs 5.7% and 2.1 vs 2.2%, respectively). There were no differences in rates of preeclampsia and gestational hypertension, cesarean and preterm delivery, or premature rupture of membranes. A sub-analysis by maternal pre-gestational BMI showed that LGA incidence was significantly higher among babies born to women with pre-gestational BMI ≥30 kg/m2 in both groups. CONCLUSION: The risk of APO was similar among Mexican women with mild untreated GDM diagnosed by IADPSG criteria, compared to pregnant women without GDM. Pre-gestational BMI was an independent risk factor for LGA.

[Assessment of progesterone levels on the day of the hCG administration as a predictor of success of antagonist stimulation protocols for IVF]. / Evaluación de la concentración de progesterona el día de la administración de hCG como predictor de éxito en protocolos de estimulación con antagonista para fertilización in vitro.

BACKGROUND: There are reports of deleterious effect when progesterone concentration is high during the follicular phase in cycles of in vitro fertilization. In our environment has not carried out a study to evaluate the pregnancy rate compared with progesterone concentration on the day of application of hCG. OBJECTIVE: To evaluate the pregnancy rate and outcome of in vitro fertilization cycle according to serum progesterone concentration on the day of application of hCG. MATERIAL AND METHODS: A retrospective, observational, cross-sectional study of 486 cycles of in vitro fertilization was done in the Centro Mexicano de Fertilidad of CEPAM (Hospital Angeles de las Lomas) from January 2009 to February 2014. We included all cases where it was used a stimulation protocol GnRH antagonist flexible scheme. RESULTS: When levels of progesterone are high, those of estradiol are also high and the number of retrieved oocytes and oocyte quality are lower. There was no difference in the percentage of fertilization, but at higher concentration of progesterone lower percentage of embryonic segmentation. Difference was recorded in the pregnancy rate only when progesterone concentration on the day of hCG application was > 4 ng/mL. CONCLUSION: Pregnancy rate decreases when the concentration of progesterone on the day of hCG application is ≥ 4 ng/mL.

[Effect of sexual abstinence on pregnancy rates after an intrauterine insemination]. / Efecto de la abstinencia sexual en las tasas de embarazo posterior a inseminación intrauterine.

BACKGROUND: There are many studies showing that more days of sexual abstinence increased sperm concentration, however, the direct influence between the days of abstinence and pregnancy rates has not been evaluated. The usual recommendation is 3-4 days prior to intrauterine insemination; this based on the interval that maximizes the number of motile sperm in the ejaculate. There are some reports with better success rate when abstinence is less than three days. OBJECTIVE: To evaluate the pregnancy rate post-intrauterine insemination according to days of sexual abstinence prior to obtaining semen sample. PATIENTS AND METHODS: A retrospective, observational and transversal study in patients attending the Mexican Center for Fertility (CEPAM) to intrauterine insemination. For analysis patients were grouped by age group, success rate and days of sexual abstinence. Continuous variables are reported as means and standard deviations; to determine statistical significance univariate logistic regression was performed. Categorical variables were evaluated in frequencies and percentages. The calculations were performed using JMP software program. RESULTS: 3,123 couples were included and increased success rate for intrauterine insemination was obtained with less than seven days of sexual abstinence. The rate of sperm retrieval is inversely proportional to the days of abstinence. CONCLUSION: A better pregnancy rate in intrauterine insemination was achieved with less than seven days of sexual abstinence and sperm retrieval rate was also recorded with fewer days of abstinence.

[Spontaneous uterine rupture in a patient with polyhydramnios as only risk factor. Case report, literature review and institutional experience]. / Rotura uterina espontánea en una paciente con polihidramnios como único factor de riesgo. Comunicación de un caso, revisión de la bibliografía y experiencia institucional.

The uterine rupture is a catastrophic obstetric complication. The main risk factor is an antecedent of uterine surgery, usually caesarean. It is reported the case of a 39-years-old patient with 37 week-pregnancy and polyhydramnios, without surgical antecedents, whose was not in labor and developed complete rupture of the lateral face of the uterus, which was spontaneous, without previous uterine scar and with a unusual outcome.
