Efficient Sequencing, Assembly, and Annotation of Human KIR Haplotypes.

Front Immunol 2020 9;11:582927. Epub 2020 Oct 9.

Center for International Blood and Marrow Transplant Research, Minneapolis, MN, United States.

The homology, recombination, variation, and repetitive elements in the natural killer-cell immunoglobulin-like receptor (KIR) region has made full haplotype DNA interpretation impossible in a high-throughput workflow. Here, we present a new approach using long-read sequencing to efficiently capture, sequence, and assemble diploid human KIR haplotypes. Probes were designed to capture KIR fragments efficiently by leveraging the repeating homology of the region. Read More

BMJ Open 2020 09 18;10(9):e038531. Epub 2020 Sep 18.

Department of Clinical Research, University of Southern Denmark, Odense, Denmark

Purpose: Cervical cancer is a major cause of death among women in Eastern Africa, and the distribution of human papillomavirus (HPV) according to HIV status is inadequately characterised in this region. In order to guide future cervical cancer preventive strategies that involve HPV testing, the Comprehensive Cervical Cancer Prevention in Tanzania (CONCEPT) study was established in 2015. The CONCEPT cohort aims to investigate the natural history of HPV and determine acquisition and persistence patterns of high-risk (HR) HPV among HIV-positive and HIV-negative women. Read More

AIDS 2020 12;34(15):2249-2258

Department of Obstetrics and Gynecology, Boston University School of Medicine, Boston, Massachusetts, USA.

Objective: HIV-infected women (WLHIV) have more than 10-fold higher risk for squamous cell cancer of the anus. Experts suggest cytology-based strategies developed for cervical cancer screening may prevent anal cancer by detecting anal cytologic or histological high-grade squamous intraepithelial lesion (hHSIL) for treatment.

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.

JCO Glob Oncol 2020 07;6:1147-1154

Indian Council of Medical Research-Indian Cancer Research Consortium, New Delhi, 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.
