Background: Mixed infection with multiple strains of the same pathogen in a single host can present clinical and analytical challenges. Whole genome sequence (WGS) data can identify signals of multiple strains in samples, though the precision of previous methods can be improved. Here, we present MixInfect2, a new tool to accurately detect mixed samples from Mycobacterium tuberculosis short-read WGS data.

Objective: To understand the current status and analyse the factors influencing frailty in older adults patients with pulmonary tuberculosis.
Methods: This retrospective case-control study included 204 older adults patients with pulmonary tuberculosis. The enrolled patients were divided into a frailty group (n = 101) and a non-frailty group (n = 103).

Recent research suggests that tuberculosis (TB) may pose a potential risk factor for osteoporosis, although the available evidence remains limited. This study aimed to comprehensively assess osteoporosis risk in TB patients through systematic review and meta-analysis methodology. Two investigators independently conducted a literature search using the Medical Literature Analysis and Retrieval System Online (MEDLINE) and Excerpta Medica Database (EMBASE) databases up to April 2024.

Infection with HIV is associated with dysregulated CD4 T cell responses to Mycobacterium tuberculosis (Mtb) and increased risk of developing tuberculosis. Mtb-specific CD4 T cells in people with HIV have diminished Th1 cytokine production capacity, thus we utilized a flow cytometry-based assay to measure CD40L expression by Mtb-specific CD4 T cells in a cytokine-independent manner. We evaluated the frequency and phenotype of Mtb-specific CD4 responses in Kenyan adults with latent Mtb infection and found that the majority of Mtb-specific CD4 T cells expressed CD40L in the absence of IFN-γ, regardless of HIV infection status.

People who use drugs show a higher incidence and prevalence of tuberculosis than people who do not use drugs in areas where Mycobacterium tuberculosis is endemic. However, this population is largely neglected in national tuberculosis programmes. Strategies for active case finding, screening, and linkage to care designed for the general population are not adapted to the needs of people who use drugs, who are stigmatised and difficult to reach.
