OLAgen: A Software Tool for Reagent Design to Expand Access to Single Nucleotide Variant Detection by the Oligonucleotide Ligation Assay.

Department of Biomedical Engineering, Vanderbilt University, Nashville, Tennessee, United States. Electronic address:
Single nucleotide variations (SNVs) and polymorphisms (SNPs) are characteristic biomarkers in various biological contexts, including pathogen drug resistances and human diseases. Tools that lower the implementation barrier of molecular SNV detection methods would provide greater leverage of the expanding SNP/SNV database. The oligonucleotide ligation assay (OLA) is a highly specific means for detection of known SNVs and is especially powerful when coupled with polymerase chain reaction (PCR).

The Antibody Mediated Prevention (AMP) trials showed that passively infused VRC01, a broadly neutralizing antibody (bNAb) targeting the CD4 binding site (CD4bs) on the HIV-1 envelope protein (Env), protected against neutralization-sensitive viruses. We identified six individuals from the VRC01 treatment arm with multi-lineage breakthrough HIV-1 infections from HVTN703, where one variant was sensitive to VRC01 (IC < 25 ug/mL) but another was resistant. By comparing Env sequences of resistant and sensitive clones from each participant, we identified sites predicted to affect VRC01 neutralization and assessed the effect of their reversion in the VRC01-resistant clone on neutralization sensitivity.

Division of Infectious Disease, University of Rochester Medical Center, Rochester, New York, USA.
Pancreatic tuberculosis (TB) is an uncommon extrapulmonary presentation of TB. Identification of coinfection with HIV may unmask not only disseminated TB but also immune reconstitution inflammatory syndrome (IRIS). We present the case of a 70-year-old Indian woman newly diagnosed with AIDS and pancreatic tuberculosis with miliary disseminated disease.

Department of Internal Medicine, St. Paul's Hospital Millennium Medical College, Addis Ababa, Ethiopia.
As the second most populated country in Africa, Ethiopia needs public health measures to control diseases that impact its population. The goal of this study is to analyse disease burdens of HBV and HCV, while also highlighting their estimated associated costs for the country. A literature review and a Delphi process reflecting input of Ethiopian experts and the National Viral Hepatitis Technical Working Group were used to complement mathematical modelling to estimate HBV and HCV disease and economic burdens.

Department of Geography, Binghamton University, New York, USA.
Background: The global burden of HIV and AIDS continues to significantly impact public health, particularly in Sub-Saharan Africa. This study investigates the spatial distribution and associated risk factors of HIV prevalence in Botswana using data from the 2021 Botswana AIDS Impact Survey (BAIS V).
Methods: The analysis included 12,653 adults aged 15-64 years and employed chi-square tests, multilevel mixed-effects regression, and spatial analysis techniques.
