Obstetric pulmonary embolism and long-term cardiovascular symptoms: a cross-sectional study in Western Mexico.

OBJECTIVES: Pulmonary embolism (PE) is an important cause of maternal mortality. There are several guidelines for its diagnosis and management, but there is little information regarding follow-up and frequency of long-term complications. The aim of the study was to determine the frequency of long-term cardiovascular symptoms in patients who had obstetric PE. METHODS: Cross-sectional study including patients who had PE during pregnancy or the puerperium. A telephone interview was conducted at least one year after PE, to determine the frequency of cardiovascular symptoms, general health, and COVID-19 infection, considering the study was conducted during the 2020 pandemic. RESULTS: In five years (2015-2019) there were eleven patients with PE, two died during the acute phase, and the rest (nine) were alive and able to answer our interview. Cardiovascular symptoms were common (6, 67 %), the most frequent were fatigue, edema, and mild dyspnea. Four patients (44 %) had slight limitation of physical activity and one (11 %) had PE recurrence. Of the six symptomatic patients four had obesity and one was overweight. CONCLUSIONS: There is a high frequency of long-term cardiovascular symptoms in patients who had PE during pregnancy or the puerperium. Stronger evidence is needed to design a long-term care pathway after obstetric PE.

Factores relacionados con la histerectomía ginecológica por patología benigna en un hospital escuela del occidente de México / Factors related to gynecological hysterectomy for benign pathology in a teaching hospital in western Mexico

Resumen OBJETIVO: Determinar las características clínicas y los desenlaces asociados con las diferentes vías de acceso elegidas para la histerectomía. MATERIALES Y MÉTODOS: Estudio retrospectivo, descriptivo y transversal consistente en el análisis de la información asentada en los expedientes de pacientes atendidas en el servicio de Ginecología del Hospital Civil de Guadalajara entre el 1 de marzo del 2019 y el 28 de febrero del 2020. En todas las pacientes se estableció la asociación entre la vía de acceso y las complicaciones. RESULTADOS: Se revisaron 790 expedientes de los que 413 reunieron los criterios de inclusión. Se practicaron 262 histerectomías abdominales, 107 por vía vaginal y 44 mediante laparoscopia. La frecuencia de complicaciones fue de 9.2%, el 54% se registró durante el procedimiento quirúrgico. La frecuencia de conversión fue de un caso para histerectomía vaginal (0.9%) y de otro para la laparoscópica (2.2%). La complicación más frecuente fue el sangrado transquirúrgico seguida del reingreso por infección del sitio quirúrgico. La cirugía vaginal fue la que menos complicaciones porcentuales registró; sin embargo, la lesión vesical fue la más común y la única en la que sucedió una defunción, secundaria a choque hipovolémico. La asociación entre la vía de acceso abdominal y las complicaciones muestra que las pacientes con histerectomía abdominal tuvieron tres veces más probabilidades de alguna complicación en comparación con el resto de los grupos. CONCLUSIONES: El riesgo de complicaciones es mayor en la histerectomía abdominal, sobre todo en pacientes con peso uterino ≥ 500 g e IMC ≥ 30. Es necesario reforzar las competencias para incrementar la frecuencia de la histerectomía vaginal. Cada vez es más necesario estar a la vanguardia en la aplicación de técnicas de mínima invasión por su ventaja de menor frecuencia de complicaciones.

Abstract OBJECTIVE: To determine the clinical characteristics and outcomes associated with the different access routes chosen for hysterectomy. MATERIALS AND METHODS: Retrospective, descriptive and cross-sectional study consisting of the analysis of the information recorded in the records of patients attended in the Gynecology service of the Civil Hospital of Guadalajara between March 1, 2019 and February 28, 2020. The association between the access route and complications was established in all patients. RESULTS: 790 files were reviewed of which 413 met the inclusion criteria. A total of 262 abdominal hysterectomies were performed, 107 vaginally and 44 laparoscopically. The frequency of complications was 9.2%, 54% of which occurred during the surgical procedure. The frequency of conversion was one case for vaginal hysterectomy (0.9%) and another for laparoscopic hysterectomy (2.2%). The most frequent complication was trans-surgical bleeding followed by readmission for surgical site infection. Vaginal surgery had the lowest percentage of complications; however, bladder injury was the most common and the only one in which a death occurred, secondary to hypovolemic shock. The association between abdominal access route and complications shows that patients with abdominal hysterectomy were three times more likely to have some complication compared to the rest of the groups. CONCLUSIONS: The risk of complications is higher in abdominal hysterectomy, especially in patients with uterine weight ≥ 500 g and BMI ≥ 30. Skills need to be strengthened to increase the frequency of vaginal hysterectomy. It is increasingly necessary to be at the forefront in the application of minimally invasive techniques because of their advantage of lower frequency of complications.

Effect of supplementation with 5,000 IU of vitamin D on the glycemic profile of women with gestational diabetes mellitus.

OBJECTIVES: The frequency of GDM and vitamin D insufficiency in Mexico is high. Vitamin D supplementation in GDM patients has shown favorable but non-homogeneous results regarding improvement of glycemic profile. The aim of the study was to assess the effects of supplementing with 5,000 IU of vitamin D on the glycemic profile of women with GDM. METHODS: A randomized clinical trial was conducted on women with GDM who received 5,000 IU of vitamin D (n=27) or a placebo (n=27) for eight weeks. Changes in vitamin D levels and metabolic parameters before and after the intervention were analyzed. RESULTS: Vitamin D vs. placebo: 25-OHD (32 vs. 26 ng/mL, p=0.006), HbA1c (6.0 vs. 6.1%, p=0.29), glucose (99 vs. 87 mg/dL, p=0.29), insulin (14 vs. 13 µIU/mL, p=0.79), HOMA-IR (3.6 vs. 2.6, p=0.55), QUICKI (0.31 vs. 0.33, p=0.55). CONCLUSIONS: Supplementation with 5,000 IU of vitamin D for eight weeks had no significant effect on the glycemic profile.

Resumen Objetivo: Comparar las concentraciones de 25-hidroxivitamina D (25[OH]D) en pacientes con y sin diabetes gestacional. Materiales y métodos: Estudio observacional, transversal y analítico consistente en la toma de muestras sanguíneas para determinar y comparar las concentraciones de 25-hidroxivitamina D. El tamaño de la muestra se determinó previamente con base en una prevalencia de 35% para la deficiencia de vitamina D, un error alfa de 0.05 y un error beta de 0.80. Resultados: Se reclutaron 784 embarazadas, 394 con diabetes gestacional y 390 sin este padecimiento. En este último grupo 51% (n = 199) tuvieron concentraciones suficientes, 33% (n = 129) concentraciones insuficientes y 16% (n = 62) concentraciones deficientes. En el grupo de mujeres con diabetes gestacional, 12% (n = 47) tuvieron concentraciones suficientes, 67% (n = 264) concentraciones insuficientes y 21% (n = 83) concentraciones deficientes. Los resultados obtenidos muestran que 88.9% (n = 350) de las mujeres con diabetes gestacional tenían concentraciones inferiores a 30 ng/mL vs 48.5% (n = 189) del grupo sin diabetes gestacional (p < 0.00001; RM: 7.69; IC95%: 5.3-11). Conclusiones: Las concentraciones inferiores a 30 ng/mL de vitamina D total son más frecuentes en pacientes con diabetes gestacional.

Abstract Objective: To compare the levels of vitamin (25[OH]D) between patients with or without gestational diabetes. Materials and methods: Analytical cross-sectional study that consisted in taking blood samples to determine and compare the concentrations of (25[OH]D) vitamin D. The sample size was previously determined considering a prevalence of 35% for vitamin D deficiency, an alpha error of 0.05 and a beta error of 0.80 for which 784 pregnant women were recruited, 394 patients with gestational diabetes and 390 without gestational diabetes. Results: In the group of patients without gestational diabetes, 51% (n = 199) had sufficient levels, 33% (n = 129) insufficient levels and 16% (n = 62) deficient levels. In the group of patients with gestational diabetes, 12% (n = 47) had sufficient levels, 67% (n = 264) insufficient levels and 21% (n = 83) deficient levels. The results obtained show that 88.9% (n = 350) of women with gestational diabetes present with levels lower than 30 ng/mL vs 48.5% (n = 189) of the group without gestational diabetes [p <0.00001 OR 7.69 (IC95%: 5.3 - 11)]. Conclusions: Levels below 30 ng/mL of total vitamin D are more frequent in patients with gestational diabetes.

Indicaciones del factor VII recombinante activado en hemorragia obstétrica grave / Use of recombinant activated Factor VII in severe obstetric hemorrhage

Resumen OBJETIVO: Describir la situación final de salud de las pacientes con hemorragia obstétrica grave (≥ 1000 mL) en quienes se indicó factor VII recombinante activado como parte del tratamiento e identificar las complicaciones atribuibles a este medicamento. MATERIALES Y MÉTODOS: Estudio retrospectivo, transversal y descriptivo efectuado en pacientes con hemorragia obstétrica grave atendidas en el Hospital Civil de Guadalajara Dr. Juan I Menchaca entre 2001 y 2017 y tratadas con factor VII recombinante activado. Se identificaron los antecedentes de importancia y se calculó la dosis promedio y cantidad de dosis de factor VII recombinante activado; se valoró la respuesta hemostática y se determinó si la diferencia en cantidad de sangrado, administración de hemoderivados y parámetros hematológicos antes y después de utilizar factor VII recombinante activado fue significativa. RESULTADOS: Se identificaron 10 pacientes en quienes se aplicó factor VII recombinante activado. La causa de hemorragia obstétrica grave fue atonía uterina en seis casos. La dosis promedio de factor VII recombinante activado fue de 91 mcg/kg. En 8 pacientes se administró una dosis y 2 dosis en 2 pacientes. En todas las pacientes se logró la hemostasia; el sangrado disminuyó significativamente posterior a la administración del factor VII recombinante activado (5075 vs 928 mL; p = 0.000) lo mismo que la cantidad de concentrados eritrocitarios trasfundidos (7 vs 3; p = 0.006). Una paciente no requirió histerectomía, otra tuvo tromboembolia pulmonar, que se trató sin problemas y ninguna paciente falleció. CONCLUSIÓN: El factor VII recombinante activado como hemostático en hemorragia obstétrica grave mostró resultados favorables y evitó la histerectomía en una paciente. Requiere vigilancia estrecha de las complicaciones trombóticas.

Abstract OBJECTIVE: To describe outcome of patients with severe obstetric hemorrhage (≥ 1000 mL) treated with rFVIIa as part of the management and to detect complications related to its use. MATERIALS AND METHODS: Retrospective, cross-sectional and descriptive study carried out in patients with severe obstetric hemorrhage treated at the Hospital Civil de Guadalajara Dr. Juan I Menchaca between 2001 and 2017 and treated with activated recombinant factor VII. We identified relevant antecedents, average dose and number of doses of rFVIIa, and hemostatic response. We determined if quantity of bleeding, administration of blood products and hematological parameters before and after using rFVIIa was significantly different. RESULTS: We identified ten patients with rFVIIa administration. The cause of severe obstetric hemorrhage was uterine atony in six cases. The average dose of rFVIIa was 91 mcg/kg; one dose was administered in eight patients and two doses in two patients. Hemostasis was achieved in all patients, bleeding decreased significantly after administration of rFVIIa (5075 mL vs 928 mL, p = 0.000) and the number of erythrocyte concentrates required 7vs 3, p = 0.006). One patient did not require a hysterectomy after rFVIIa administration; one patient presented pulmonary thromboembolism and recovered without complications, no patient died. CONCLUSION: rFVIIa administration as a hemostatic in severe obstetric hemorrhage had favorable results, preventing hysterectomy in one patient. Follow-up requires close monitoring of thrombosis.

[Related factors to lack of implementation of antenatal corticosteroids]. / Factores relacionados con la falta de aplicación de glucocorticoides antenatales.

BACKGROUND: Despite the known benefits of antenatal corticosteroids therapy its use in clinical practice is not generalized. OBJECTIVE: To identify factors related to antenatal corticosteroids non administration. METHODS: Cross-sectional and descriptive study that included patients admitted to Hospital Civil de Guadalajara "Dr. Juan I. Menchaca", who had indication for antenatal corticosteroids therapy but did not receive it. Variables: antenatal corticosteroids therapy prescription, factors related to antenatal corticosteroids therapy non administration and lapsed time between diagnosis and birth. RESULTS: Antenatal corticosteroids therapy were not prescribed in 79 (94%) of 84 patients. Main related factors were imminent birth and severe maternal complication. The longer amount of time from diagnosis to birth was before hospitalization (91 vs. 9%, p <0.0005). CONCLUSION: The biggest and best opportunity for the administration of inducers of fetal lung maturity is during prenatal care, when cases with increased risk of preterm birth are detected.

[Modified cesarean-hysterectomy technique for management of placenta accreta]. / Técnica cesárea-histerectomía modificada para el tratamiento del acretismo placentario.

UNLABELLED: BAKGROUND: Obstetric hemorrhage is a major cause of maternal morbidity. The increasing number of births via cesarean has increased the incidence of placenta accreta worldwide. As new techniques aimed at reducing maternal mortality and morbidity have emerged with varying results. OBJECTIVES: To describe the surgical technique used in our hospital for management of placenta accreta. Report outcomes and maternal complications. METHODS: Descriptive study, data were obtained from clinical records of patients diagnosed with placenta accreta and whose management was by our modified technique cesarean-hysterectomy by a multidisciplinary team. We included patients who were treated at the Hospital Civil de Guadalajara Dr. Juan I. Menchaca in the period from April 1, 2008 to November 1, 2012. RESULTS: 23 patients were included. The mean gestational age at Doppler ultrasound diagnosis was 31 +/- 3 weeks and for termination of pregnancy was 34 +/- 1 weeks of gestation. Only 5 patients were admitted to intensive care, one patient suffer bladder injury noticed and repaired. CONCLUSIONS: Our modified technique cesarean-hysterectomy for management of placenta accreta has reduced mortality and morbidity in our hospital as well as injuries to nearby organs and hospital stay.

Complicaciones maternas a corto plazo en pacientes con cesárea / Short-term complications in patients with cesarean sections

Objetivo: Determinar si las pacientes con cesárea tienen un mayor número de complicaciones que las de parto y describir el tipo de complicaciones observadas. Sujetos y métodos: Se revisaron los expedientes de 1.017 pacientes que finalizaron su gestación en el Hospital Materno-Infantil Vall d'Hebron durante el primer trimestre de 2007. Resultados: Para una tasa de cesáreas del 22%, la incidencia de complicaciones maternas fue del 18% y del 6% en los partos (riesgo relativo = [RR] 3,1; intervalo de confianza [IC] del 95%, 2,4-15.1). Las complicaciones más frecuentes fueron la infección de herida (7,5%), la transfusión de sangre (5,3%) y la hemorragia (3,1%); la endomiometritis fue más común en el grupo de pacientes de parto (el 1,6 frente al 1,3%). Conclusiones: La cesárea tiene un riesgo de complicaciones tempranas 3 veces mayor que el parto. La menor incidencia de endomiometritis poscesárea quizá es consecuencia de la profilaxis antibiótica, pero se requieren más estudios para llegar a una conclusión al respecto

Objective: To determine whether patients whoundergo cesarean section are at higher risk ofcomplications than those who have a vaginal birthand to describe the complications observed.Subjects and methods: We reviewed the clinicalrecords of 1017 patients who gave birth at theMaterno- Vall d’Hebron Maternity and ChildHospital in the first trimester of 2007.Results: For a cesarean rate of 22%, the incidenceof maternal complication was 18%, while forvaginal birth the incidence was 6% (RR 3.1, 95% CI2.4-15.1). The most frequent complications werewound infection (7.5%), transfusions (5.3%) andhemorrhage (3.1%); endomyometritis was morecommon in the group with vaginal births (1.6% vs.1.3%).Conclusions: Cesarean section is associated with athree times higher risk of complications thanvaginal birth. The lower incidence ofendomyometritis after cesarean sections may be aconsequence of antibiotic prophylaxis, but furtherstudies are required to draw firm conclusions onthis topic
