Clinical and Epidemiologic Evaluation of Inconclusive COVID-19 PCR Results Using a Quantitative Algorithm

The inconclusive severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) polymerase chain reaction (PCR) result causes confusion and delay for infection prevention precautions and patient management. We aimed to develop a quantitative algorithm to assess and interpret these inconclusive results.

Prioritizing Health Care and Employment Resources During COVID-19: Roles of Benevolent and Hostile Ageism

Benevolent and hostile ageism are subtypes of ageism that characterize older adults as incompetent. With benevolent ageism, older adults are also viewed as warm.

Validation of the STANDARD Q COVID-19 antigen test in Vojvodina, Serbia

Since COVID-19 pandemic is a global crisis, tests with high sensitivity and specificity are crucial for the identification and management of COVIid-19 patients.

Diagnosis of COVID-19 Based on Symptomatic Analysis of Hospital Healthcare Workers in Belgium: Observational Study in a Large Belgian Tertiary Care Center During Early COVID-19 Outbreak

Cough (82%), headache (78%), myalgia (70%), loss of smell or taste (40%) and fever more than or equal to 37.5 °C (76%) were significantly higher among those infected. It is the combination of COVID-19 symptoms that could allow for a rapid diagnostic appraisal of the disease.

A Comparison of Five SARS-CoV-2 Molecular Assays With Clinical Correlations

Comparative assessments of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) molecular assays are warranted to assess real-world performance

Universal COVID-19 screening of 4040 health care workers in a resource-limited setting: an Egyptian pilot model in a university with 12 public hospitals and medical centers

To address this concern, universal (non-symptom-based) screening of HCWs was piloted. All participants were tested for SARS-CoV-2 using reverse transcription polymerase chain reaction (RT-PCR) The proportion of infection among asymptomatic HCWs (n = 54/616) was 8.8% (95% CI: 6.7-11.3); 6/54 (11.1%) had a high rate of concussion, 7/54 had a concussion, and 9/10 had pneumonia.

Screening for SARS-CoV-2 antibodies in convalescent plasma in Brazil: Preliminary lessons from a voluntary convalescent donor program

Plasma collection began in two Brazilian hospitals for treatment of severe/critical patients. Donor's weight, days between disease onset and serial plasma collection are important predictors for neutralizing antibody titer.

Effects of Training and Feedback on Accuracy of Predicting Rectosigmoid Neoplastic Lesions and Selection of Surveillance Intervals by Endoscopists Performing Optical Diagnosis of Diminutive Polyps

Real-time differentiation of polyps (1-5 mm) during endoscopy could replace histopathology analysis. According to guidelines, implementation of optical diagnosis into routine practice would require it to identify rectosigmoid neoplastic lesions with a negative predictive value (NPV) of more than 90%.
