The Evolution of Next-Generation Sequencing Technologies.

The genetic information that dictates the structure and function of all life forms is encoded in the DNA. In 1953, Watson and Crick first presented the double helical structure of a DNA molecule. Their findings unearthed the desire to elucidate the exact composition and sequence of DNA molecules.

Healthcare Access Domains and Treatment as Mediators of Ovarian Cancer Racial Disparities in Survival: A Structural Equation Modeling Analysis in SEER-Medicare.

Racial differences in healthcare access (HCA) may contribute to disparities in ovarian cancer (OC) survival. We used structural equation models (SEM) to examine associations between race and HCA domains (affordability, availability, accessibility) in relation to overall and OC-specific mortality. Non-Hispanic (NH)-Black and non-Black (Hispanic, NH-White) women diagnosed with OC in 2008-2015 were identified from SEER-Medicare.

Enhancing clinical genomic accuracy with panelGC: a novel metric and tool for quantifying and monitoring GC biases in hybridization capture panel sequencing.

Accurate assessment of fragment abundance within a genome is crucial in clinical genomics applications such as the analysis of copy number variation (CNV). However, this task is often hindered by biased coverage in regions with varying guanine-cytosine (GC) content. These biases are particularly exacerbated in hybridization capture sequencing due to GC effects on probe hybridization and polymerase chain reaction (PCR) amplification efficiency.

COVID-19 and Rates of Cancer Diagnosis in the US.

Importance: US cancer diagnoses were substantially lower than expected during the COVID-19 pandemic in 2020. A national study on the extent to which rates recovered in 2021 has not yet been conducted.

Objective: To examine observed vs expected cancer rate trends for January 2020 to December 2021.
