Objective: Bictegravir or dolutegravir based antiretroviral therapy are first-line HIV treatments. However, no trial has recruited enough participants to estimate the most effective treatment, and there is little evidence on the comparative effectiveness of bictegravir and other available antiretrovirals, like efavirenz and raltegravir.

Methods: We emulated a four-arm target trial using country-wide data from Mexico.

Natural resistance to Mycobacterium tuberculosis (Mtb) infection in some people with HIV (PWH) is unexplained. We performed single cell RNA-sequencing of bronchoalveolar lavage cells, unstimulated or ex vivo stimulated with Mtb, for 7 PWH who were TST & IGRA positive (called LTBI) and 6 who were persistently TST & IGRA negative (called resisters). Alveolar macrophages (AM) from resisters displayed a baseline M1 macrophage phenotype while AM from LTBI did not.

Introduction: The Virginia Memory Project (VMP) is a statewide epidemiological registry for Alzheimer's disease and related disorders (ADRD) and other neurodegenerative conditions. It aims to support dementia research, policy, and care by leveraging the Centers for Disease Control (CDC) Healthy Brain Initiative (HBI) Roadmap.

Methods: To capture comprehensive data, the VMP integrates self-enrollment and automatic enrollment using Virginia's All-Payer Claims Database (APCD).

Conventional x-ray radiography relies on attenuation differences in the object, which often results in poor contrast in soft tissues. X-ray phase imaging has the potential to produce higher contrast but can be difficult to utilize. Instead of grating-based techniques, analyzer-based imaging, also known as diffraction enhanced imaging (DEI), uses a monochromator crystal with an analyzer crystal after the object.

Nuclear factor (erythroid-derived 2)-like 2 (Nrf2) is a key regulator of cell detoxification, which maintains homoeostasis in healthy cells and promotes chemoresistance in cancer cells. Controlling the expression of this transcription factor is therefore of great interest. There are many compounds that have been shown to induce Nrf2 expression, but ligands that can inhibit Nrf2 are scant.
