Association of Single-Nucleotide Variants in ACE2 with the Persistence of Positive qPCR Test for SARS-CoV-2 in Healthcare Professionals During the First Wave of the COVID-19 Pandemic.

The persistence of qPCR positivity for SARS-CoV-2 in individuals who recovered from COVID-19 raised several questions regarding viral transmission, with a special interest in healthcare professionals who may pose a risk of transmitting SARS-CoV-2. This issue highlights the necessity for identifying the genetic risk factors associated with persistent SARS-CoV-2 infection. A promising target for achieving this goal is the angiotensin-converting enzyme 2 () gene, which has been associated with clinical characteristics of COVID-19 infection, such as severity.

Viral Hepatitis in Pregnant Mexican Women: Its Impact in Mother-Child Binomial Health and the Strategies for Its Eradication.

Viral hepatitis is the main cause of infectious liver disease. During pregnancy, a risk of vertical transmission exists both during gestation and at birth. HAV, HBV, and HCV might progress similarly in pregnant and non-pregnant women.

Body mass index implications in intrahepatic cholestasis of pregnancy and placental histopathological alterations.

Introduction And Objectives: Intrahepatic cholestasis is a frequent disease during pregnancy. It is unknown if liver function alterations produce specific placental lesions. The aim of this study was to evaluate placental histopathological changes in patients with intrahepatic cholestasis of pregnancy (ICP), and to explore correlations between the placental histopathology and hepatic function alteration or patient comorbidities, and body mass index.

High Plasmatic Levels of Advanced Glycation End Products are Associated with Metabolic Alterations and Insulin Resistance in Preeclamptic Women.

Aims: The purpose of this study was to investigate the association between plasmatic levels of advanced end glycation products (AGEs) and the metabolic profile in subjects diagnosed with preeclampsia, due to the known relation of these molecules with oxidative stress and inflammation, which in turn are related with PE pathogenesis.

Background: It has been reported that increased levels of AGEs are observed in patients with preeclampsia as compared with healthy pregnant subjects, which was mainly associated with oxidative stress and inflammation. Besides, in women with preeclampsia, there are metabolic changes such as hyperinsulinemia, glucose intolerance, dyslipidemia, among others, that are associated with an exacerbated insulin resistance.

Liver disease in pregnancy: Medical aspects and their implications for mother and child.

Liver disease during pregnancy is more common than expected and may require specialized intervention. It is important to determine if changes in liver physiology may develop into liver disease, to assure early diagnosis. For adequate surveillance of mother-fetus health outcome, liver disease during pregnancy might require intervention from a hepatologist.
