The feminization of medicine in Latin America: 'More-the-merrier' will not beget gender equity or strengthen health systems.

This viewpoint addresses the lack of gender diversity in medical leadership in Latin America and the gap in evidence on gender dimensions of the health workforce. While Latin America has experienced a dramatic change in the gender demographic of the medical field, the health sector employment pipeline is rife with entrenched and systemic gender inequities that continue to perpetuate a devaluation of women; ultimately resulting in an under-representation of women in medical leadership. Using data available in the public domain, we describe and critique the trajectory of women in medicine and characterize the magnitude of gender inequity in health system leadership over time and across the region, drawing on historical data from Mexico as an illustrative case.

Impact of SARS-CoV-2 on pregnancy and neonatal outcomes: An open prospective study of pregnant women in Brazil.

Objectives: To determine the incidence and risk of adverse obstetric and neonatal outcomes according to SARS-CoV-2 infection severity in pregnant women.

Method: Open prospective study of pregnant women tested for SARS-CoV-2 by serological and molecular assays during pregnancy or delivery in two hospitals in Sao Paulo, Brazil from April 12, 2020, to February 28, 2021. Five groups were considered for analysis: C0, negative COVID-19 results and no COVID-19 symptoms; C1, positive COVID-19 results, and no symptoms; C2, positive COVID-19 results with mild symptoms; C3, positive COVID-19 results with moderate symptoms; and C4, positive COVID-19 results with severe symptoms.

Risk factors for oxygen requirement in hospitalized pregnant and postpartum women with COVID-19.

Objective: To identify risk factors for Oxygen (O) needs in pregnant and postpartum women with COVID-19.

Methods: Prospective cohort involving pregnant women hospitalized with COVID-19 from April to October 2020. The oxygen need was analyzed regarding risk factors: demographic characteristics, clinical and laboratory parameters at hospital admission, and chest Computer Tomography (CT) findings.

Expression of matrix metalloproteinases and their inhibitors at the implantation site in ampullary ectopic pregnancies.

Objective: This study investigated the qualitative and semi-quantitative expression of metalloproteinases (MMP) and their tissue inhibitors (TIMP) in trophoblastic tissue during ampullary ectopic pregnancies and correlated that expression with the degree of tubal invasion.

Study Design: It is a prospective study that included 34 patients diagnosed with ampullary tubal pregnancy who underwent salpingectomy. A histological evaluation of the depth of trophoblastic invasion in the tubes obtained was performed.

Use of low-molecular-weight heparin in severe paraquat poisoning: a case report.

Background: Acute paraquat ingestion remains a leading cause of mortality in developing countries. There is currently no evidence that treatment with high-dose immunosuppressants and antioxidants improves survival in patients with paraquat poisoning, and better options are urgently needed. Here, we describe the unexpected survival and recovery of a patient with a potentially fatal paraquat poisoning.
