Article Title: Saliva as alternative to naso-oropharyngeal swab for SARS-CoV-2 detection by RT-qPCR: a multicenter cross-sectional diagnostic validation study
Article Snippet: .. Diagnostic validity estimates (sensitivity, specificity, positive predictive value or PPV, negative predictive value or NPV, and accuracy) and their 95% CIs were calculated, using the MedCalc online calculator , for three scenarios: (1) SalivaDirect RT-qPCR as index test and NOS RT-qPCR as reference test, (2) SE RT-qPCR as index test and NOS RT-qPCR as reference test, and (3) SalivaDirect RT-qPCR, SE RT-qPCR and NOS RT-qPCR as index tests separately benchmarked against a composite reference standard (CRS). ..

Article Title: Health risk assessment for exposure to heavy metals in soils in and around E-waste dumping site
Article Snippet: Electrical and electronic waste recycling is done mainly by the informal (unauthorised) sector in developing countries.. People usually dump these wastes in an open area leading to contamination of air, soil, and water.. The objective of this study was to assess heavy metals contamination of soil and quantify and compare human health risks based on two different methods i.e., using epidemiological data, and US EPA’s methodology for risk assessment due to exposure to toxic heavy metals.

Article Title: Aberrant Methylation of 20 miRNA Genes Specifically Involved in Various Steps of Ovarian Carcinoma Spread: From Primary Tumors to Peritoneal Macroscopic Metastases
Article Snippet: To determine clinically significant parameters, such as the sensitivity (Sn) and specificity (Sp), the odds ratio (OR), and relative risk (RR), and to perform the ROC analysis, the MedCalc online calculator ( https://www.medcalc.org/calc/diagnostic_test.php , accessed on 15 November 2021) was used.

Biomarker Discovery:

Article Title: The use of Reflectance Confocal Microscopy to diagnose Malignant Melanoma and Lentigo Maligna in the United Kingdom: A Prospective Observational Trial at a Single Centre.
Article Snippet: Background Previous work with reflectance confocal microscopy (RCM) has shown high sensitivity and specificity for malignant melanoma (MM); however, to date, there have been no studies with a UK cohort.. Objectives To use RCM prospectively to accurately diagnose MM and lentigo maligna (LM) in a private UK secondary care, single-clinician setting; and to assess the potential of RCM to be used as a routine screening procedure.. Methods In total, 597 patients with a differential clinical diagnosis of MM or LM were consecutively recruited.
