Diagnostic accuracy of rapid antigen tests for COVID-19 compared to the viral genetic test in adults: a systematic review protocol.

Objective: The objective of this diagnostic accuracy review is to evaluate the effectiveness of rapid antigen tests versus viral genetic PCR-based tests on COVID-19 diagnostic accuracy in adults 18 years and over.

Introduction: Due to the rapidly changing nature of the COVID-19 pandemic, it is imperative that clinicians have access to the most relevant and effective tools and information required to combat this disease. Testing strategies are being developed continuously and need to be evaluated to ensure their appropriate implementation into clinical practice.

Quantitative fluorescence in situ hybridization and its ability to predict bladder cancer recurrence and progression to muscle-invasive bladder cancer.

Fluorescence in situ hybridization (FISH) testing is used to detect bladder cancer in urine specimens. The purpose of this study was to determine whether there are associations between the percentage of chromosomally abnormal cells by FISH and time to bladder cancer recurrence and progression to metastasis. Clinical records were searched to identify patients with urine FISH results, history of non-invasive bladder cancer, and at least one follow-up pathological diagnosis.

Boundaries for biofilm formation: humidity and temperature.

Environmental conditions which define boundaries for biofilm production could provide useful ecological information for biofilm models. A practical use of defined conditions could be applied to the high-level nuclear waste repository at Yucca Mountain. Data for temperature and humidity conditions indicate that decreases in relative humidity or increased temperature severely affect biofilm formation on three candidate canister metals.
