( ) is the world's most deadly infectious pathogen and new drugs are urgently required to combat the emergence of multi-(MDR) and extensively-(XDR) drug resistant strains. The bacterium specifically upregulates sterol uptake pathways in infected macrophages and the metabolism of host-derived cholesterol is essential for long-term survival Here, we report the development of antitubercular small molecules that inhibit the cholesterol oxidases CYP125 and CYP142, which catalyze the initial step of cholesterol metabolism. An efficient biophysical fragment screen was used to characterize the structure-activity relationships of CYP125 and CYP142, and identify a non-azole small molecule that can bind to the heme cofactor of both enzymes.

Individuals diagnosed with tuberculosis (TB) and multidrug-resistant (MDR) TB may struggle to return to work after they have completed a rehabilitation program. Multidrug-resistant tuberculosis (MDRTB) has been seen as a condition that is resistant to treatment, hence causing individuals to be economically in-active for considerable periods of time. The aim of the current study was to explore the views of individuals living with MDRTB, individuals with TB, and health professionals treating individuals with TB and MDRTB about the development of a vocational rehabilitation program.

Intramedullary spinal tuberculomas constitute a small percentage of spinal tuberculosis. These, in combination with brain tuberculomas, are an uncommon manifestation of central nervous system (CNS) tuberculosis. This report details a unique case of a 32-year-old retroviral disease-positive male who presented with a two-month history of symmetrical quadriparesis and recent seizures.

Subclavian artery pseudoaneurysms (SAPs) are rare and most often secondary to trauma. On the contrary, a mycotic origin is exceedingly rare, and defining this etiology can become challenging. We present a rare case of a tuberculous SAP in a young patient.

Background: Latent TB infection (LTBI) affects one fourth of the global population. Currently, there is an absence of an optimal strategy for distinguishing between active tuberculosis (aTB) and LTBI. While some researchers have explored cytokines other than interferon-gamma (IFN-γ) as biomarkers, results have shown significant variability in their ability to differentiate between these conditions.
