Evaluation of a Chip-Based, Point-of-Care, Portable, Real-Time Micro PCR Analyzer for the Detection of High-Risk Human Papillomavirus in Uterine Cervix in India.

Purpose: Currently available human papillomavirus (HPV) detection devices are expensive, requiring a continuous power supply, high-priced reagents, skilled laboratory personnel, and infrastructure. These make it difficult to implement primary HPV screening in high-risk (HR) populations, particularly in low-income settings such as in India. The objective of our study was to evaluate the diagnostic performance of a point-of-care, portable, battery-operated device called Truenat, which detects 4 HR HPV genotypes (16, 18, 31, and 45), as a potentially cost-effective alternative to conventional HPV diagnostic tests.

Role of Mitochondrial DNA (mtDNA) Variations in Cancer Development: A Systematic Review.

Molecular testing in diagnosis of indeterminate thyroid cytology: Trends and drivers.

Fine needle aspiration (FNA), the cornerstone of diagnosis in thyroid swellings, fails to render a definitive diagnosis in about 20% to 30% of cases that are reported as indeterminate on cytology. Since the clinical management in thyroid rests on the risk of malignancy (ROM) in a given nodule, this distinction between "benign" and "possibly malignant" assumes paramount clinical importance. Over the last two decades, tremendous progress has been achieved in our understanding of the molecular basis of thyroid pathologies leading to identification of several genetic alterations that could potentially be exploited for diagnostic, prognostic and therapeutic purposes.

Exosomal miRNAs in hepatitis B virus related liver disease: a new hope for biomarker.

The World Health Organisation, in its 2019 progress report on HIV, viral hepatitis and STDs indicates that 257 million people are afflicted with chronic HBV infections, of which, 1 million patients lose their lives every year due to HBV related chronic liver diseases including serious complications such as liver cirrhosis and hepatocellular carcinoma. The course of HBV infection and associated liver injury depend on several host factors, genetic variability of the virus, and the host viral interplay. The challenge of medical science is the early diagnosis/identification of the potential for development of fatal complications like liver cirrhosis and HCC so that timely medical intervention can improve the chances of survival.

Inadequate clinical data on Pap test request form: Where are we headed in the era of precision medicine?

The request form accompanying any sample to a clinical laboratory constitutes an important communication tool between the clinician and the laboratory personnel. Much has been written about the inadequacy of pertinent clinical data on the request slips for hematology and biochemistry tests and its impact on the subsequent test interpretation and error liability. Although the cytology laboratories, including those performing cervical cytology, have to deal with a similar problem of lack of clinical information critical to the proper interpretation of cytomorphologic features, the issue has not been attended to or reported adequately in the literature.
