COVID-19 Infection in Pregnancy: PCR Cycle Thresholds, Placental Pathology, and Perinatal Outcomes.

(1) This study aimed to evaluate characteristics, perinatal outcomes, and placental pathology of pregnant women with or without SARS-CoV-2 infection in the context of maternal PCR cycle threshold (CT) values. (2) This was a retrospective case-control study in a third-level health center in Mexico City with universal screening by RT-qPCR. The association of COVID-19 manifestations, preeclampsia, and preterm birth with maternal variables and CT values were assessed by logistic regression models and decision trees. (3) Accordingly, 828 and 298 women had a negative and positive test, respectively. Of those positive, only 2.6% of them presented mild to moderate symptoms. Clinical characteristics between both groups of women were similar. No associations between CT values were found for maternal features, such as pre-gestational BMI, age, and symptomatology. A significantly higher percentage of placental fibrinoid was seen with women with low CTs (<25; p < 0.01). Regarding perinatal outcomes, preeclampsia was found to be significantly associated with symptomatology but not with risk factors or CT values (p < 0.01, aOR = 14.72). Moreover, 88.9% of women diagnosed with COVID-19 at <35 gestational weeks and symptomatic developed preeclampsia. (4) The data support strong guidance for pregnancies with SARS-CoV-2 infection, in particular preeclampsia and placental pathology, which need further investigation.

Prevalence, clinical features, and outcomes of SARS-CoV-2 infection in pregnant women with or without mild/moderate symptoms: Results from universal screening in a tertiary care center in Mexico City, Mexico.

The perinatal consequences of SARS-CoV-2 infection are still largely unknown. This study aimed to describe the features and outcomes of pregnant women with or without SARS-CoV-2 infection after the universal screening was established in a large tertiary care center admitting only obstetric related conditions without severe COVID-19 in Mexico City. This retrospective case-control study integrates data between April 22 and May 25, 2020, during active community transmission in Mexico, with one of the highest COVID-19 test positivity percentages worldwide. Only pregnant women and neonates with a SARS-CoV-2 result by quantitative RT-PCR were included in this study. Among 240 pregnant women, the prevalence of COVID-19 was 29% (95% CI, 24% to 35%); 86% of the patients were asymptomatic (95% CI, 76%-92%), nine women presented mild symptoms, and one patient moderate disease. No pregnancy baseline features or risk factors associated with severity of infection, including maternal age > 35 years, Body Mass Index >30 kg/m2, and pre-existing diseases, differed between positive and negative women. The median gestational age at admission for both groups was 38 weeks. All women were discharged at home without complications, and no maternal death was reported. The proportion of preeclampsia was higher in positive women than negative women (18%, 95% CI, 10%-29% vs. 9%, 95% CI, 5%-14%, P<0.05). No differences were found for other perinatal outcomes. SARS-CoV-2 test result was positive for nine infants of positive mothers detected within 24h of birth. An increased number of infected neonates were admitted to the NICU, compared to negative neonates (44% vs. 22%, P<0.05) and had a longer length of hospitalization (2 [2-18] days vs. 2 [2-3] days, P<0.001); these are potential proxies for illness severity. This report highlights the importance of COVID-19 detection at delivery in pregnant women living in high transmission areas.

Pregnancy in teenagers with heart disease / Embarazo en pacientes adolescentes con cardiopatía

Abstract The prevalence of pregnancy in adolescent women is high in Mexico and represents a public health problem. The pregnant teenager with heart disease has a high probability of complications during pregnancy and the delivery, which carries a risk of death of both the mother and the product. In many cases the pregnancy should have been avoided, planned or interrupted, however the majority at this age is vulnerable and although certain cases must be interrupted by their high risk of maternal-fetal death, prevention and legal aspects should be considered. In some cases the woman wants a pregnancy although her health condition does not allow it, but there are options of adoption or recourse to a surrogate belly. In response to this growing social problem, the National Cardiology Institute Ignacio Chávez and National Institute of Perinatology, with the coordination of Ministry of Health in Mexico, started a pregnancy prevention module within a clinic of follow-up of cardiopathy and pregnancy. This review raises the global problem in our country that occupies the first place in pregnancies in adolescents, with more than 400,000 pregnancies a year and the form of immediate response in a multidisciplinary way.

Resumen La prevalencia de embarazo en mujeres adolescentes es muy alta en México, y representa un problema de salud pública. La adolescente embarazada con cardiopatía tiene altas posibilidades de complicaciones durante el embarazo y su resolución, lo que pone en riesgo la vida tanto de la madre como del producto. En muchos casos el embarazo debió ser evitado, planeado o interrumpido, sin embargo la mayoría a esta edad es vulnerable y si bien ciertos casos deben ser interrumpidos por su alto riesgo de muerte materno-fetal, es fundamental considerar la prevención y los aspectos legales. En algunos casos la mujer desea un embarazo aunque su condición de salud no se lo permite, pero existen opciones de adopción o recurrir a un vientre subrogado. Atendiendo este problema social cada vez más creciente, el Instituto Nacional de Cardiología Ignacio Chávez, en coordinación con la Comisión Coordinadora de la Secretaría de Salud y el Instituto Nacional de Perinatología, echaron a andar un módulo de prevención de embarazo dentro de una clínica de seguimiento de cardiopatía y embarazo. Esta revisión plantea el problema global en nuestro país, que ocupa el primer lugar en embarazos en adolescentes, con más de 400 mil embarazos al año y la forma de dar respuesta inmediata de manera multidisciplinaria.

Improvement of quality of life and menopausal symptoms in climacteric women treated with low-dose monthly parenteral formulations of non-polymeric microspheres of 17ß-estradiol/progesterone.

OBJECTIVE: To evaluate the short term effect over menopausal symptoms and quality of life (QoL) of monthly parenteral formulations of 17ß-estradiol (E)/progesterone (P) non-polymeric microspheres. METHODS: This is a secondary analysis of a multicenter, randomized, single-blinded study that included peri- and post-menopausal symptomatic women assigned to receive a monthly intramuscular injection of 0.5 mg E + 15 mg P (Group A, n = 34), 1 mg E + 20 mg P (Group B, n = 24), or 1 mg E + 30 mg P (Group C, n = 26) for 6 months. Intensity of menopausal symptoms was assessed before and after treatment with the Greene Climacteric Scale (GCS) and QoL with the Utian Quality of Life Scale (UQoLS). RESULTS: Menopausal symptoms improved for all groups at six months evidenced by lower cluster/sub-cluster GCS scores. Equally, there was an overall trend for QoL improvement for all groups evidenced by higher domain UQoLS scores at six months; but only significant for the emotional (Groups A and B) and occupational domains (Groups A and C). CONCLUSION: The three low-dose continuous sequential intramuscular monthly formulations of E/P microspheres exerted a positive effect over menopausal symptoms and QoL. Long-term research is warranted with these formulations. CLINICAL TRIAL REGISTRATION: Clinicaltrials.gov Identifiers NCT 00775242.

Treatment of menopausal symptoms with three low-dose continuous sequential 17ß-estradiol/progesterone parenteral monthly formulations using novel non-polymeric microsphere technology.

OBJECTIVE: To analyze the short-term efficacy and safety over menopausal symptoms of three low-dose continuous sequential 17ß-estradiol (E)/progesterone (P) parental monthly formulations using novel non-polymeric microspheres. METHODS: This was a multicenter, randomized, single blinded study in which peri- and postmenopausal women were assigned to receive a monthly intramuscular injection of 0.5 mg E + 15 mg P (Group A, n = 34), 1 mg E + 20 mg P (Group B, n = 24) or 1 mg E + 30 mg P (Group C, n = 26) for 6 months. Primary efficacy endpoints included mean change in the frequency and severity of hot flushes and the effect over urogenital atrophy symptoms at 3 and 6 months. Safety variables included changes in the rate of amenorrhea, endometrial thickness and histopathology, and local and systemic adverse events. RESULTS: Compared to baseline at month 6, the three treatment schemes significantly decreased the rate of urogenital atrophy symptoms and the frequency (mean number per day) and severity (mean number graded as moderate and severe per month) of hot flushes. No differences in studied efficacy parameters were observed between studied groups at baseline or at the end of the study. For all groups the most frequent adverse event was pain at the injection site; however they were all rated as mild. At the end of the study peri- and postmenopausal women displayed no significant changes in endometrial thickness or histopathology in all treated groups. The rate of amenorrhea at the end of the study decreased for all studied groups yet was less evident among postmenopausal women as compared to perimenopausal ones. CONCLUSIONS: The three low-dose continuous sequential intramuscular monthly treatments of E/P using novel microsphere technology were effective at reducing menopausal symptoms at short-term with a low rate of adverse events. More long-term and comparative research is warranted to support our positive findings.

Observational study of the local tolerability of injectable progesterone microspheres.

BACKGROUND: As intramuscular progesterone administration is associated with local intolerance, the purpose of this work was to determine the local tolerability of a new progesterone microsphere suspension, administered by intramuscular injection. METHODS: An observational, longitudinal, prospective, analytical, multicenter, active pharmacovigilance study was conducted. Two hundred and seven progesterone microsphere administrations were evaluated. Patients evaluated pain, burning sensation, pruritus and dysesthesia. Physicians evaluated erythema, pallor, petechia, ecchymosis, bleeding, edema, induration, abscess, macule, papule, vesicle and pustule. Local tolerability was evaluated using a visual analog scale (100-mm line) on the day of administration, and subsequently on days 3 and 7. Local symptoms were evaluated by patients and local signs by the attending physicians. RESULTS: On the day of application, 68.4% of the administered doses were associated with 'absent' or 'mild' pain, rising to 91.2% on the 7th day; 83.0% of doses were associated with 'absence' of or a 'mild' burning sensation on the day of administration, rising to 99.5% on day 7. On administration day, 13.2% reported 'mild' erythema and 1.0% 'moderate' erythema, and 3.9% of doses had 'mild' induration and 0.5% 'moderate' induration, which increased to 16.6 and 2.9% on day 3, respectively. The values for pallor, ecchymosis, bleeding, edema and pustule were lower than 10 mm (of 100 mm) on the application day and behaved similarly in subsequent days. There were no reports of petechia, abscess, macule, papule or vesicle with the dose application. CONCLUSIONS: Progesterone microspheres were well tolerated without serious or unexpected adverse effects.

Solicitud de reversión de oclusión tubaria bilateral. Factores asociados / Request for recanalization in patients operated on for bilateral tubal ligation. Associated factors

Introducción: la cada vez más común solicitud de reversión a la oclusión tubaria bilateral refleja arrepentimiento y la deficiente información que reciben las pacientes.Objetivos: identificar los motivos más frecuentes de retractación, determinar las características de las pacientes solicitantes de reversión y describir los resultados de la cirugía. Material y métodos: diseños transversal comparativo. Se incluyeron 126 mujeres con oclusión tubaria bilateral: 66 solicitantes de reversión a la cirugía. El estudio se efectuó en 10 hospitales de ginecoobstetricia. Variables: historia reproductiva, motivos de solicitud de oclusión tubaria bilateral y de arrepentimiento, número de consultas para recanalización, información acerca de la cirugía y el resultado. La información se recolectó entrevistando a las usuarias. Resultados: mayor número de mujeres solicitantes de reversión se dedicaba al hogar, tenía tres o menos hijos y menos hijos varones. El intervalo entre la oclusión y la solicitud de reversión fue de cinco años. Los motivos principales: nuevo matrimonio (55.4 por ciento), deseo de otro embarazo (16.9 por ciento), fallecimiento de algún hijo (9.2 por ciento) y presión conyugal (9.2 por ciento). Las mujeres solicitantes recibieron entre una y 20 consultas; 48 (72 por ciento), información acerca de la cirugía; sólo a 35 (73 por ciento) se les efectuó reversión, las restantes no cubrieron los criterios; 14 (40 por ciento) se embarazaron después de la cirugía. Conclusión: es relevante identificar las condiciones de estabilidad conyugal y el grado de comprensión de las pacientes con respecto a al método definitivo de planificación familiar. Ambas situaciones estuvieron relacionadas con la solicitud de recanalización.

Técnicas quirúrgicas simplificadas para esterilización reproductiva: satisfacción de usuarios y médicos / Simplified surgical techniques for reproductive sterilization: user and physician satisfaction

Objetivo: estimar la satisfacción de los usuarios intervenidos con oclusión tubaria bilateral y vasectomía sin bisturí, y de los médicos que las practican.Material y métodos: estudio transversal descriptivo. Variables en los usuarios: características sociodemográficas, información y satisfacción. Usuario satisfecho: aquél que consideró fue atendido con amabilidad, recibió apoyo y trato adecuado. Variables en los médicos: características profesionales, capacitación para las técnicas y satisfacción profesional. Médico satisfecho: quien respondió le agradaba practicar estas cirugías pues esto le permitía ampliar sus conocimientos o mejorar su desarrollo en el área. Se invitó a los usuarios y al personal de salud a participar voluntariamente. La recolección de los datos se realizó por medio de una entrevista, utilizando para ello un instrumento precodificado.Resultados: se interrogaron 57 médicos, 742 pacientes intervenidos con vasectomía sin bisturí y 527 con oclusión tubaria bilateral. Los primeros mostraron satisfacción profesional, principalmente con la vasectomía sin bisturí, mejor aceptada que la oclusión tubaria bilateral como procedimiento quirúrgico. Los segundos refirieron haber tenido información oportuna en cuanto a la anestesia y el procedimiento; de igual forma manifestaron estar satisfechos con la atención.Conclusiones: la utilización de los métodos quirúrgicos simplificados es satisfactoria para los pacientes y para los médicos de unidades de primer y segundo nivel

Vasectomía en unidades de medicina familiar: análisis del seguimiento a pacientes / Vasectomy in family medicine units: analysis of patient follow-up

Introducción: el proceso de atención de la vasectomía sin bisturí, además de la consejería y la cirugía, incluye el seguimiento para corroborar la azoospermia; sin embargo más de 50 por ciento de pacientes no lo concluye.Objetivo: evaluar el seguimiento posvasectomía y los criterios del personal médico.Material y métodos: en un estudio observacional se entrevistaron pacientes vasectomizados y médicos de 36 clínicas del Instituto Mexicano del Seguro Social. De los vasectomizados se registró información sobre el seguimiento, aparición de complicaciones, cumplimiento de las citas para revisión posquirúrgica, espermatobioscopia y revisión de resultados. De los médicos se registraron criterios de revisión posquirúrgica para solicitar espermatobioscopia y de evaluación de resultados (alta o fracaso.)Resultados: se entrevistaron 2063 pacientes; 94 por ciento había recibido información, sin embargo, sólo 3.5 por ciento completó el seguimiento. Los pacientes no finalizaron el seguimiento por falta de tiempo, olvido, incompatibilidad con el horario de trabajo y desinformación. También se entrevistaron 62 médicos, la mayoría de los cuales conocía las normas. Su criterio para solicitar espermatobioscopia fue practicarla cumplidas 20 o más eyaculaciones posvasectomía. En caso de espermatobioscopia positiva, solicitaron nuevo examen. Consideraron fracaso una segunda espermatobioscopia positiva. Su criterio de alta fue la azoospermia.Conclusiones: la falta de información y motivación en los pacientes y las barreras organizacionales impiden un seguimiento apropiado. El criterio médico coincide con los establecidos institucionalmente
