Objetivo. Buscar toda la información y evidencia disponible sobre el SARS-CoV-2 -que surgió en estos primeros 4 meses de 2020- y el embarazo. Metodología. Revisión sistemática en las bases de datos PubMed y Google Scholar, hasta el 25 de abril de 2020. Se buscó artículos publicados relacionados con mujeres embarazadas infectadas con SARS-CoV-2. No hubo restricción de idioma. La búsqueda se extendió a las referencias de los artículos encontrados. Resultados. La enfermedad COVID-19 en mujeres embarazadas se caracteriza porque más del 90% de las pacientes evoluciona en forma leve, 2% requiere ingresar a las unidades de cuidados intensivos. Una muerte materna ha sido reportada. La prematuridad es alrededor de 25%, con predominio de recién nacidos prematuros tardíos; aproximadamente el 9% se complica con rotura prematura de membranas; la mortalidad perinatal es baja o similar a la de la población general y no se ha demostrado la transmisión vertical. Conclusiones. Los ginecólogos obstetras deben prepararse para atender cada vez más casos con COVID-19 y, por lo tanto, es necesario tener su conocimiento. La enfermedad evoluciona de la misma manera que en las no embarazadas, genera mayor prematuridad, no se ha demostrado la transmisión vertical, pero hay altas posibilidades de transmisión horizontal durante el parto vaginal.

Ammonia is an energy-dense liquid hydrogen carrier and fuel whose accessible dissociation chemistries offer promising alternatives to hydrogen electrolysis, compression and dispensing at scale. Catalytic ammonia reforming has thus emerged...

Objectives: To report the maternal and neonatal results of patients infected with COVID-19 in Panama. Methods: The study is based on the analysis of pregnant women with COVID-19, in 5 hospitals in the Republic of Panama. The inclusion criteria were: Patients with or without symptoms, positive RT-PCR for SARS-CoV-2 in the period from March 23 to 6 months after, whose births were attended in one of those 5 hospitals and who signed the consent. Data was obtained at the time of diagnosis of the infection and at the time of termination of pregnancy for the mother and newborn. Results: 253 patients met the inclusion criteria. Most were diagnosed in the third trimester (89.3%). 10.3% of the patients presented in a severe form of COVID-19. The most frequent complication was pre-eclampsia and if we add gestational hypertension they represent 21.2%; most of the patients terminated the pregnancy by caesarean section (58%). 26.9% (95% CI 21.3-32.9%) of the births were premature, and perinatal mortality was 5.4% (95% CI 3.0-9.0%). There was a need for mechanical ventilation in 5.9% (95% CI 3.6-9.6%) of the cohort and there were four maternal deaths (1.6% - 95% CI 0.6-4.0%). Conclusions: This study of pregnant women infected with COVID-19 and diagnosed with RT-PCR shows serious maternal complications such as high admission to the ICU, need for mechanical ventilation and one death in every 64 infected. Frequent obstetric complications such as hypertension, premature rupture of membranes, high rate of prematurity and perinatal lethality were also seen.
