Balón de Bakri en el control de la hemorragia obstétrica. Experiencia de cinco años / Bakri's balloon in the control of obstetric hemorrhagia. Five years experiencie

Resumen OBJETIVO: Evaluar los desenlaces con la aplicación del balón de Bakri para contener la hemorragia posparto. MATERIALES Y MÉTODOS: Estudio descriptivo, analítico, observacional y retrospectivo efectuado en pacientes atendidas en el Hospital Central, San Luis Potosí, a quienes de enero 2012 a diciembre 2017 se les colocó un balón de Bakri para contener la hemorragia posparto. Se excluyeron los expedientes incompletos y las pacientes a quienes se colocó el balón en otra institución. El análisis estadístico se procesó en una hoja de Excel Office 2013. RESULTADOS: Se realizaron 143 colocaciones del balón de Bakri, 84.06% (n = 121) durante el posparto, 9% (n =13) en la poscesárea y 6.2% (n = 9) durante la cesárea. La colocación del balón se consideró exitosa en 90.2% (n = 129); hubo 14 (9.79%) fallas en el control de la hemorragia que ameritaron otro procedimiento. El 48.9% de las pacientes no tenían factores de riesgo. El promedio de permanencia del balón fue de 20 h. Se registró una muerte obstétrica directa, por choque hipovolémico. CONCLUSIONES: El éxito del balón de Bakri para contener la hemorragia obstétrica fue similar al reportado en la bibliografía. Su aplicación es una estrategia de segunda línea, secundaria a atonía y complicaciones bajas.

Abstract OBJECTIVE: To evaluate the outcomes with the application of the Bakri balloon to contain postpartum hemorrhage. MATERIALS AND METHODS: Descriptive, analytical, observational and retrospective study carried out in patients attended at the Central Hospital in San Luis Potosi who between the months of January 2012 to December 2017 had a Bakri balloon placed to contain postpartum hemorrhage. Incomplete records and patients who had the balloon placed in another institution were excluded. Statistical analysis was processed in an Excel Office 2013 spreadsheet. RESULTS: 143 Bakri balloon placements were performed, 84.06% (n = 121) during postpartum, 9% (n =13) post cesarean section and 6.2% (n = 9) during cesarean section. Balloon placement was considered successful in 90.2% (n = 129); there were 14 (9.79%) failures to control bleeding that warranted another procedure. Of the patients, 48.9% had no risk factors. The average length of stay was 20 hours. One direct obstetric death was recorded, due to hypovolemic shock. CONCLUSIONS: The success of the Bakri Balloon in containing obstetric hemorrhage was similar to that reported in the literature. Its application is a second line strategy, secondary to atony and low complications.

Urinary Metabolomic Profile of Neonates Born to Women with Gestational Diabetes Mellitus.

Gestational diabetes mellitus (GDM) is one of the most frequent pregnancy complications with potential adverse outcomes for mothers and newborns. Its effects on the newborn appear during the neonatal period or early childhood. Therefore, an early diagnosis is crucial to prevent the development of chronic diseases later in adult life. In this study, the urinary metabolome of babies born to GDM mothers was characterized. In total, 144 neonatal and maternal (second and third trimesters of pregnancy) urinary samples were analyzed using targeted metabolomics, combining liquid chromatographic mass spectrometry (LC-MS/MS) and flow injection analysis mass spectrometry (FIA-MS/MS) techniques. We provide here the neonatal urinary concentration values of 101 metabolites for 26 newborns born to GDM mothers and 22 newborns born to healthy mothers. The univariate analysis of these metabolites revealed statistical differences in 11 metabolites. Multivariate analyses revealed a differential metabolic profile in newborns of GDM mothers characterized by dysregulation of acylcarnitines, amino acids, and polyamine metabolism. Levels of hexadecenoylcarnitine (C16:1) and spermine were also higher in newborns of GDM mothers. The maternal urinary metabolome revealed significant differences in butyric, isobutyric, and uric acid in the second and third trimesters of pregnancy. These metabolic alterations point to the impact of GDM in the neonatal period.

Changes in PPAR-γ Expression Are Associated with microRNA Profiles during Fetal Programming due to Maternal Overweight and Obesity.

BACKGROUND: There has been a global increase in the prevalence of obesity in pregnant women in recent years. Animal studies have shown that intrauterine environment associated with maternal obesity leads to epigenetic changes. However, the effects of epigenetic changes occurring before birth in response to maternal conditions have not been clearly characterized in humans. OBJECTIVE: The aim of the study was to analyze peroxisome proliferator-activated receptor (PPAR)-γ expression in cell cultures from newborns from mothers with overweight and obesity, in response to in vitro metabolic challenges and their relationship with microRNA profile and cytokine expression. Methods/Study design: The profile of circulating microRNAs from 72 mother-child pairs (including healthy infants born to normal weight [n = 35], overweight [n = 25], and obese [n = 12] mothers) was determined through real-time PCR, and the PPAR-γ expression in peripheral blood mononuclear cell cultures from offspring was analyzed after in vitro challenges. RESULTS: miR-146a, miR-155, and miR-378a were upregulated in overweight mothers, while miR-378a was upregulated in obese mothers compared to normal weight mothers. In children from overweight mothers, miR-155 and miR-221 were downregulated and miR-146a was upregulated, while offspring of mothers with obesity showed downregulation of miR-155, miR-221, and miR-1301. These microRNAs have direct or indirect relation with PPAR-γ expression. In vitro exposure to high triglyceride and exposure to miR-378a induced a higher expression of PPAR-γ in cells from offspring of mothers with overweight and obesity. In contrast, cells from offspring of mothers with obesity cultured with high glucose concentrations showed PPAR-γ downregulation. IL-1ß, IL-6, and TNF-α expression in cells of offspring of overweight and obese mothers differed from that of offspring of normal weight mothers. Limitation of our study is the small sample size. CONCLUSION: The blood microRNA profile, and in vitro PPAR-γ and inflammatory cytokine expression in cells of newborn infants are associated with maternal obesity indicating that epigenetic marks may be established during intrauterine development. Key Message: Neonatal microRNA profile is associated with maternal weight. Neonatal microRNA profile is independent of maternal microRNA profile. PPAR-γ expression in newborn cell cultures is affected by maternal weight.

Placental exosomes isolated from urine of patients with gestational diabetes exhibit a differential profile expression of microRNAs across gestation.

Placenta­derived exosomes play an important role in cellular communication both in the mother and the fetus. Their concentration and composition are altered in several pregnancy disorders, such as gestational diabetes mellitus (GDM). The isolation and characterization of placental exosomes from serum, plasma and tissues from patients with GDM have been previously described; however, to the best of our knowledge, to date, there is no study available on placental exosomes isolated from urine of patients with GDM. In the present study, placental exosomes were purified from urine the 1st, 2nd and 3rd trimester of gestation. Placental exosomes were characterized by transmission electron microscopy in cryogenic mode and by western blot analysis, confirming the presence of exosomal vesicles. The expression profile of five microRNAs (miR­516­5p, miR­517­3p, miR­518­5p, miR­222­3p and miR­16­5p) was determined by RT­qPCR. In healthy pregnant women, the expression of the miRNAs increased across gestation, apart from miR­516­5p, which was not expressed at the 2nd trimester. All the miRNAs examined were downregulated in patients with GDM at the 3rd trimester of gestation. The downregulated miRNAs affected several metabolic pathways closely associated with the pathophysiology of GDM. This provides further evidence of the regulatory role of miRNAs in the GDM. This also suggests that the of urinary exosomes may be an excellent source of biomarkers and therapeutic targets.

Urinary Metabolites Altered during the Third Trimester in Pregnancies Complicated by Gestational Diabetes Mellitus: Relationship with Potential Upcoming Metabolic Disorders.

Gestational diabetes mellitus (GDM) is a disorder in pregnancy with highest impact in the future life of both mother and newborn. Increasing incidence, economic impact, and potential for severe GDM-related pregnancy complications are some factors that have motivated the deep study of physiopathology, risk factors for developing GDM, and potential biomarkers for its diagnosis. In the present pilot study, we analyzed the urinary metabolome profile of GDM patients in the 3rd trimester of pregnancy, when GDM is already established and the patients are under dietary and pharmacological control. An untargeted metabolomics method based on liquid chromatography⁻mass spectrometry analysis was developed to identify differentially expressed metabolites in the GDM group. We identified 14 metabolites that are significantly upregulated in the urine of GDM patients, and, more importantly, we identified those related with the steroid hormone biosynthesis and tryptophan (TRP) metabolism pathways, which are associated with GDM pathophysiology. Thus, these metabolites could be screened as potential prognostic biomarkers of type two diabetes mellitus, coronary artery disease and chronic renal failure in future follow-up studies with GDM patients.

Prevalencia de morbilidad materna extrema en un hospital de segundo nivel de San Luis Potosí, México / Prevalence of extreme maternal morbidity in a second-level hospital in San Luis Potosí, México

Resumen OBJETIVO Determinar la prevalencia de la morbilidad materna extrema en un hospital de segundo nivel de atención de San Luis Potosí. MATERIALES Y MÉTODOS Estudio retrospectivo y transversal efectuado en pacientes obstétricas de cualquier edad gestacional atendidas en el servicio de Ginecología y Obstetricia del Hospital Central Dr. Ignacio Morones Prieto de San Luis Potosí entre el 1 de enero y el 31 de diciembre de 2016 que cumplieron con criterios de morbilidad materna extrema para la inclusión en los indicadores de salud de la OMS. Se identificaron variables epidemiológicas y obstétricas y el análisis estadístico descriptivo se realizó con medidas de tendencia central. RESULTADOS Durante el periodo de estudio se registraron 4691 recién nacidos vivos. Del total de pacientes ingresadas al servicio, 383 pacientes cumplieron con 1 o más criterios de morbilidad materna extrema y 21 se excluyeron por no contar con un expediente clínico completo y no ser posible verificar el diagnóstico de ingreso y egreso. Cumplieron uno o más criterios de morbilidad materna extrema 362 pacientes, que corresponde a una prevalencia de morbilidad materna extrema de 7.7% tomando en cuenta cualquiera de los tres grupos de clasificación. La razón de morbilidad materna extrema calculada fue de 77.1 por cada 1000 recién nacidos vivos. Solo 17% (n = 62) de las pacientes ingresó a cuidados intensivos para su atención. CONCLUSIONES Los resultados de este estudio están dentro de los límites de prevalencia reportados en la bibliografía. Es importante continuar con el reporte y publicación de estos casos para estudiar y mejorar el proceso de atención de estas pacientes y evitar el incremento de la mortalidad materna.

Abstract OBJECTIVE To estimate the prevalence of near miss patients in a secondary care level hospital in San Luis Potosí. MATERIALS AND METHODS A retrospective and cross-sectional study was made in obstetricians patients of any gestational age attended in the Gynecology and Obstetrics service of the Central Hospital Dr. Ignacio Morones Prieto of San Luis Potosí among the January 1 and December 31, 2016 that met the morbidity criteria maternal health for inclusion in WHO health indicators. They were identified epidemiological and obstetric variables and the descriptive statistical analysis is performed with measures of central tendency. RESULTS During the study period, 4691 live newborns were registered. Of the total number of patients admitted to the service, 383 patients met 1 or more criteria of extreme maternal morbidity, and 21 were excluded because they did not have a file complete clinical and not be possible to verify the diagnosis of admission and discharge. Met one or more criteria of extreme maternal morbidity 362 patients, who corresponds to a prevalence of extreme maternal morbidity of 7.7% considered any of the three classification groups. The maternal extreme morbidity ratio calculated was 77.1 per 1000 live births. Only 17% (n = 62) of the patients was refereed an intensive care. CONCLUSION The results we obtained in this study are equivalent to the ones mentioned in the already published literature. It's important to continue with this kind of studies in order to get a better medical approach of these problems and thus avoid the raise in maternal deaths.
