RESUMO
Background: COVID-19 disease is the leading cause of maternal death in Mexico. The data published to date indicate that pregnancy favors severe forms of the disease. Objective: To describe the clinical, obstetric and perinatal characteristics of pregnant women with COVID-19 disease treated at the UMAE "Luis Castelazo Ayala" of the Instituto Mexicano del Seguro Social. Material and methods: Observational, cross-sectional and retrospective study of pregnant women with COVID-19 treated from March to December 2020. The epidemiological characteristics, complications and perinatal results were analyzed with descriptive and inferential statistics. Results: 133 patients included: 84.5% with mild disease, 8 % moderate and 8.5% severe and critical. Pre-existing comorbidities: obesity, diabetes and hypothyroidism. Main symptoms: cough, headache, fever, rhinorrhea and anosmia. In severe and critical cases, tachycardia, tachypnea, and hypoxemia were present. Lymphoneutropenia, hyperglycemia, and transaminasemia were seen in severe and critical forms. Fibrinogen and D dimer stayed unchanged. Preterm delivery, oligohydramnios, gestational hypertension, severe preeclampsia, and pneumonia were the main complications. 75% of the newborns without complications. Conclusions: The clinical behavior of the disease was mostly mild and even in moderate cases, and even in moderate as well as severe and complicated cases, the binomial results were favorable. There was no maternal death.
Introducción: la enfermedad COVID-19 en el embarazo es la primera causa de muerte materna en México, y se ha reportado que favorece las formas graves de la enfermedad. Objetivo: describir las características clínicas, obstétricas y perinatales de pacientes embarazadas con enfermedad COVID-19 atendidas en la UMAE "Luis Castelazo Ayala" del Instituto Mexicano del Seguro Social (IMSS). Material y métodos: estudio observacional, transversal y retrospectivo de pacientes embarazadas con COVID-19 atendidas de marzo a diciembre del 2020. Las características epidemiológicas, complicaciones y resultados perinatales se analizaron con estadística descriptiva e inferencial. Resultados: se incluyeron 133 pacientes: 84.5% presentaron enfermedad leve, 8% moderada y 8.5% severa y crítica. Las comorbilidades preexistentes fueron: obesidad, diabetes e hipotiroidismo. Los principales síntomas: tos, cefalea, fiebre, rinorrea y anosmia. En casos severos y críticos la taquicardia, taquipnea e hipoxemia estuvieron presentes. En las formas severa y crítica se observaron: linfoneutropenia, hiperglucemia y transaminasemia. El fibrinógeno y dímero D sin cambios. El parto pretérmino, el oligohidroamnios, la hipertensión gestacional, la preeclampsia severa y la neumonia fueron las principales complicaciones. El 75% de los recién nacidos no preentaron complicaciones. Conclusiones: el comportamiento clínico de la enfermedad fue, en su mayoría, leve, e incluso en los casos moderados así como en los severos y complicados los resultados del binomio fueron favorables. No hubo muerte materna ni se evidenció transmisión vertical.

Resumen: OBJETIVO: Evaluar las ventajas de practicar o no la ligadura de arterias hipogástricas antes del alumbramiento o previo a la histerectomía modificada en el tratamiento quirúrgico de la inserción anómala de la placenta. MATERIALES Y MÉTODOS: Estudio de serie de casos, retrospectivo, transversal y comparativo efectuado en la Unidad Médica de Alta Especialidad, Hospital de Ginecoobstetricia 4 Luis Castelazo Ayala, de 2013 a 2019. Criterios de inclusión: pacientes con inserción anómala de placenta a quienes se practicó o no ligadura de arterias hipogástricas antes del alumbramiento o previo a la histerectomía modificada. Criterios de exclusión: pacientes que no finalizaron el embarazo en el hospital o la información en el expediente estaba incompleta. Parámetros de estudio: sangrado transoperatorio, transfusión sanguínea, morbilidad posoperatoria e ingreso a cuidados intensivos. Los desenlaces se analizaron con estadística descriptiva e inferencial. RESULTADOS: Se evaluaron 285 pacientes; 57% (n = 164) con placenta previa, 27% (n = 78) marginal y 15% (n = 43) normoinserta. El espectro de placenta acreta se encontró en 34% (n = 91) de la muestra. En el grupo de placenta previa la aplicación de la técnica disminuyó el sangrado transoperatorio (p = 0.005) y la transfusión sanguínea (p = 0.05). En pacientes con espectro de placenta acreta hubo una reducción del sangrado transoperatorio (p < 0.01), menores transfusión sanguínea (p = 0.01), ingreso a cuidados intensivos (p < 0.001) y días de estancia en cuidados intensivos (p = 0.0001). CONCLUSIONES: La ligadura de arterias hipogástricas antes del alumbramiento o previo a la histerectomía modificada en el tratamiento quirúrgico de la inserción anómala de la placenta mostró un máximo beneficio en los grupos de placenta previa y espectro de placenta acreta.
Abstract OBJECTIVE: To evaluate the advantages of performing and not performing "Hypogastric artery ligation prior to delivery or modified hysterectomy" in the surgical management of anomalous placental insertion. MATERIALS AND METHODS: A retrospective, cross-sectional, comparative, retrospective case series study conducted at the Unidad Médica de Alta Especialidad, Hospital de Ginecoobstetricia 4 Luis Castelazo Ayala, from 2013 to 2019. Inclusion criteria: patients with abnormal placental insertion who underwent hypogastric artery ligation before delivery or before modified obstetric hysterectomy, compared with those who did not have hypogastric artery ligation. Exclusion criteria: patients who did not terminate the pregnancy in the hospital or the information in the file was incomplete. Study parameters: transoperative bleeding, blood transfusion, postoperative morbidity and admission to intensive care. Outcomes were analyzed with descriptive and inferential statistics. RESULTS: 285 patients were evaluated; 57% (n = 164) with placenta previa, 27% (n = 78) marginal and 15% (n = 43) normoinsert. The placenta accreta spectrum was found in 34% (n = 91) of the sample. In the placenta previa group, the application of the technique decreased transoperative bleeding (p = 0.005) and blood transfusion (p = 0.05). In patients with placenta accreta spectrum there was a reduction of transoperative bleeding (p < 0.01), lower blood transfusion (p = 0.01), intensive care admission (p < 0.001) and days of intensive care stay (p = 0.0001). CONCLUSIONS: Hypogastric artery ligation before delivery and before modified hysterectomy in the surgical treatment of anomalous placental insertion showed maximum benefit in the placenta previa and spectrum of placenta accreta groups.
RESUMO
OBJECTIVE: Recently, a study based on the analysis of accelerated evolution of related genes at birth identified the follicle-stimulating hormone receptor (FSHR) as a possible candidate for the development of preterm delivery. Additionally, FSHR expression has been described in extragonadal tissue including the placenta. Therefore, the aim of the present study was to determine the association between the N680S polymorphism of the follicle-stimulating hormone receptor and preterm birth in a population of Hispanic women. METHODS: Placenta samples were obtained from 64 women who had preterm births and 54 control cases. DNA was extracted and genotyped for the N680S FSHR gene polymorphism by polymerase chain reaction-restriction fragment length polymorphism. The χ2 test and t-test were used to calculate statistical significance. RESULTS: Statistically significant differences in genotype frequencies for the N680S polymorphism were observed between preterm and term groups (p = .04). Based on the Akaike information criterion values, the dominant model showed that the NN genotype had a significantly increased risk of preterm birth compared with the SS + NS genotype (OR 2.52, 95% CI 1.20-5.33, p = .02). CONCLUSIONS: The results herein suggest that the FSHR polymorphism N680S is significantly associated with preterm birth in the Hispanic population.
