Article Synopsis
- A study conducted in Curitiba, Brazil, aimed to analyze the characteristics of COVID-19 among healthcare workers (HCWs) by testing over 1,000 samples for the virus between June and December 2020.* -
- Results indicated that 32.7% of HCWs tested positive for SARS-CoV-2, with higher infection rates found among symptomatic (39.2%) compared to asymptomatic (15.9%) workers; high-risk hospital departments had the most cases.* -
- The study highlights the importance of early diagnosis and isolation of infected HCWs to help control the spread of the virus, especially since those in direct contact with COVID-19 patients have a higher risk of infection.*
Unlabelled: Since the beginning of the pandemic, few papers describe the placenta's morphological and morphometrical features in SARS-CoV-2-positive pregnant women. Alterations, such as low placental weight, accelerated villous maturation, decidual vasculopathy, infarcts, thrombosis of fetal placental vessels, and chronic histiocytic intervillositis (CHI), have been described.
Objective: To analyze clinical data and the placental morphological and morphometric changes of pregnant women infected with SARS-CoV-2 (COVID-19 group) in comparison with the placentas of non-infected pregnant women, matched for maternal age and comorbidities, besides gestational age of delivery (Control group).
Objectives: This study aims to detect the SARS-CoV-2 infection prevalence in asymptomatic pregnant women.
Methods: A group of 195 asymptomatic pregnant women who attended the prenatal care outclinic and to the obstetric emergency department was tested concomitantly for SARS-CoV-2 by RT-PCR and serological tests.
Results: The virus was detected by RT-PCR in two (1.
Objective: To assess the diagnostic performance of lateral flow immunochromatographic assays (LFAs) of 4 different manufacturers to identify SARS-CoV-2 antibodies (IgM, IgG, or total), comparing them with the nucleic acid amplification test (NAAT) or the clinical defined test (definite or probable SARS-CoV-2 infection, respectively).
Methods: One hundred nineteen serum samples were randomly selected by convenience and distributed in the following groups: (1) group with SARS-CoV-2 infection (n = 82; RT-qPCR positive [definite, n = 70] and probable [n = 12]); (2) other diseases (n = 27; other viruses identified [n = 8] and SARS of other etiologies [n = 19]); and (3) healthy control group (n = 10). LFAs of 4 manufacturers were compared: MedTest Coronavirus (COVID-19) IgG/IgM (MedLevensohn, Brazil); COVID-19 IgG/IgM ECO Test (Ecodiagnóstica, Brazil); Camtech COVID-19 IgM/IgG Rapid Test Kit (Camtech Diagnostics Pte Ltd, Singapore); and 1-Step COVID-19 Test for total antibodies (Guangzhou Wondfo Biotech Co.
Article Synopsis
- Human adenovirus (HAdV) is a notable viral pathogen linked to neurological diseases, especially in patients with weakened immune systems, but its role in meningoencephalitis is still unclear.
- A study analyzed 373 cerebrospinal fluid (CSF) samples from patients with suspected viral neurological infections, finding that HAdV was present in only 1.08% of cases, primarily in women with underlying health issues.
- HAdV infections typically occurred in the fall and winter, and although it was infrequently detected in CNS infections, it should be considered in immunocompromised patients due to potential encephalitis.
