Objectives: To evaluate the clinical manifestations and maternal-perinatal results of COVID-19 infection associated with pregnancy. Material and methods: Eight electronic databases (Science Direct, Pubmed, Lilacs, Scielo, Redalyc, LitCovid, EBSCO and Scopus) were reviewed. Full text primary studies in Spanish and English were considered; published between January 1 and May 15, 2020; and performed in pregnant women with a confirmed diagnosis of COVID-19 (reverse transcription polymerase chain reaction [RT-PCR]. Results: 15 studies were included that reported 224 cases of pregnancy-associated COVID-19 infection, mainly in third trimester pregnant women (13/15). Cough and fever were the main clinical manifestations reported in all the investigations. Less than a third of studies show abdominal pain as an obstetric manifestation that motivates attention seeking. The epidemiological history o...

Objectives. To determine the estrogenic activity of hydroalcoholic extract of the fruit of aguaje (Mauritia flexuosa L) in ovariectomized rats. Materials and methods. 54 Sprague-Dawley rats from 2 1/2 to 3 months of age were grouped randomly into six groups: intact females + saline, ovariectomized + saline, hydroalcoholic extract of three different doses aguaje, ovariectomized + ethinylestradiol. After ovariectomy treatment was started by intragastric for 5 weeks. At 2 weeks of treatment a vaginal smear was made for 7 days to determine the cell maturation. At the end of the treatment was performed euthanasia to study the bone tissue of the proximal metaphysis of the tibia and the uterus was dissected for weighing. Results. The group that received doses of 500 mg/kg had more rats that had vaginal cell maturation in contrast to the lower dose. In the study of bone was not significant estro...

Objective: To describe the perception of the online teaching and learning process of the Research course among obstetrics students at a Peruvian university during the COVID-19 pandemic. Materials and methods: An observational, descriptive and cross-sectional design was used. Data were collected through an online survey administered to 73 eighth-term obstetrics students who completed the Research course between October 2020 and January 2021, conducted entirely online. A questionnaire, validated by expert panel’s review (Aiken’s V: 0.95) and demonstrating high reliability (Cronbach’s alpha: 0.93), gathered data on tutoring, course performance, teaching strategies, learning outcomes and student satisfaction. Results: A total of 95.89 % of the students were female and 49.31 % reported that they simultaneously studied and worked while completing the course. Regarding their research expe...
