Researchers conducted a study to determine whether SARS-CoV-2 viral RNA detected in the bloodstreams of patients with COVID-19 is reflective of viremia or related to host immune responses and outcomes.
Researchers compared the results of self-collected saliva and anterior nasal swab samples vs nasopharyngeal swab samples collected by healthcare workers used to test for SARS-CoV-2 infection.
Researchers conducted a study to determine the accuracy of a novel 29-messenger RNA blood-based host-response assay for identifying bacterial and viral infections in patients admitted to the emergency department.
Researchers investigated the role of time to positivity as a prognostic and diagnostic tool for patients with bloodstream infections caused by Enterococcus spp.
Researchers assessed the performance of a pneumonia panel in relation to clinical measures and outcome variables.
The researchers’ main goal was to assess whether the marked increase in avidity of antibodies noted 7 to 8 months after an infection was also substantial in older adults.
Risk increased for new sequelae attributed to SARS-CoV-2 infection, including chronic respiratory failure, myocarditis, anxiety, fatigue.
This study’s main objective was to compare the SARS-CoV-2 test results using a self-collected swab sample with the results of a professionally collected swab sample.
The study authors gathered data on individual HIV viral load trajectories at the population-level following the introduction of universal test and treat in sub-Saharan Africa.
Researchers conducted testing during a nursing home outbreak where paired respiratory specimens were collected to assess performance of the BinaxNOW antigen test compared to virus culture and RT-PCR.
Investigators adapted a simple compartmental epidemic model to simulate SARS-CoV-2 spread, death, and associated costs in the US in an effort to understand the role of at home testing.
Researchers examined mammography and colonoscopy rates among commercially insured US adults before and after the declaration of the COVID-19 public health emergency to assess changes in screening.
Using artificial intelligence algorithm techniques, the system identifies regions of interest during colonoscopy, which can help clinicians determine whether further assessment is needed.
Researchers examined correlations between SAT, IMAT, and pectoralis PM areas from chest CT with mortality in individuals with COPD.
Researchers systematically reviewed literature to understand the performance and sensitivity of alternative sample types compared with that of nasopharyngeal swabs for the diagnosis of SARS-CoV-2.
The io instrument processes a single-use cartridge that contains all reagents for testing collected vaginal swabs and male urine samples.
Researchers conducted a cross-sectional study among HCP at 4 large health care systems in 3 US states to assess the risk factors associated with SARS-CoV-2 seropositivity.
Study authors assessed the economic trade-offs of expanding and accelerating testing for SARS-CoV-2 across the United States in different transmission scenarios.
Study authors assessed the diagnostic accuracy of saliva NAAT for COVID-19 due to the increased resources, such as trained personnel, required for nasopharyngeal swab NAAT.
A new point-of-care lateral flow assay featured the same sensitivity as mycobacterial culture in detecting tuberculosis meningitis in adults with HIV.
