Background: Tuberculosis (TB) remains a major public health problem in China and globally, particularly among older adults. This study aimed to examine secular trends in TB mortality among older adults in China and the net effects of age, period, and cohort.

Methods: Data from the National Disease Surveillance Points (DSPs) system were analyzed using Joinpoint regression to determine annual changes in TB mortality among individuals aged 60 years and older from 2004 to 2021.

New Frontiers in Fighting Mycobacterial Infections: Venom-Derived Peptides.

Probiotics Antimicrob Proteins

January 2025

Department of Mycobacteriology and Pulmonary Research, Pasteur Institute of Iran, Tehran, Iran.

Notwithstanding the indefatigable endeavors to develop effective anti-mycobacterial therapies, mycobacterial infections still present a tough problem for medicine today. The problem is further complicated by the disquieting surge of drug-resistant mycobacterial pathogens, which considerably narrows the existing therapeutic options. Thus, there is a genuine need to discover novel anti-mycobacterial drugs.

Inference of multiple mergers while dating a pathogen phylogeny.

Syst Biol

January 2025

School of Life Sciences and Department of Statistics, University of Warwick, UK.

The vast majority of pathogen phylogenetic studies do not consider the possibility of multiple merger events being present, where a single node of the tree leads to more than two descendent branches. These events are however likely to occur when studying a relatively small population or if there is high variability in the reproductive chances. Here we consider the problem of detecting the presence of multiple mergers in the context of dating a phylogeny, that is determining the date of each of the nodes.

Multifunctional Mycobacterial Topoisomerases with Distinctive Features.

ACS Infect Dis

January 2025

Department of Microbiology and Cell Biology, Indian Institute of Science, C.V. Raman Avenue, Bangalore 560012, India.

Tuberculosis (TB) continues to be a major cause of death worldwide despite having an effective combinatorial therapeutic regimen and vaccine. Being one of the most successful human pathogens, retains the ability to adapt to diverse intracellular and extracellular environments encountered by it during infection, persistence, and transmission. Designing and developing new therapeutic strategies to counter the emergence of multidrug-resistant and extensively drug-resistant TB remains a major task.

Background: In Nigeria, men constitute over half of the people notified with tuberculosis (TB), experience longer delays before reaching care, and are estimated to account for two thirds of people who miss out on care. The higher TB risk and burden in men has implications for the whole population and reaching them earlier with TB services will reduce onward transmission in households, communities, and workplaces. The absence of a comprehensive guidance and the lack of substantial empirical evidence on TB care approaches that are responsive to the needs of men in Nigeria exacerbates this problem.
