Background: Tuberculosis (TB) control in Georgia follows the World Health Organization-recommended DOTS strategy, and has reached global TB control targets in the treatment of susceptible TB; however, the management of drug-resistant forms of TB still represents a serious problem. A countrywide drug resistance survey (DRS) found that the prevalence of multidrug-resistant TB (MDR-TB) was respectively 6.8% and 27.4% in new and previously treated TB cases.
Objective: To determine the prevalence of and risk factors for drug resistance among TB patients to improve case management and control of drug-resistant TB.
Methods: Extensive social, clinical and bacteriological data were collected from patients hospitalized at the National Centre for Tuberculosis and Lung Diseases, Georgia, between 2005 and 2007.
Results: Of 605 patients, resistance was observed in 491 (81.2%); MDR-TB was found in 261 (43.1%; 51/222 [23%] new cases and 210/383 [55%] previously treated cases), monoresistant TB in 130 (21.5%), poly-resistant TB in 67 (11.1%) and extensively drug-resistant TB in 33 (5.5%). Female sex, living in the densely populated capital, family TB contact and previous TB treatment were associated with risk of MDR-TB.
Conclusions: These findings confirm the necessity of improving infection control measures and of standardized treatment for drug-resistant TB patients.

Background: Beta-lactams remain the first-line treatment of infections despite the increasing global prevalence of penicillin-resistant/non-susceptible strains. We conducted a cross-sectional household survey in a rural community in northern Vietnam in 2018-2019 to provide prevalence estimates of penicillin non-susceptible (PNSP) carriage and to investigate behavioural and environmental factors associated with PNSP colonization. The data presented will inform the design of a large trial of population-based interventions targeting inappropriate antibiotic use.

Background: The Arp2/3 complex is a key regulator of tumor metastasis, and targeting its subunits offers potential for anti-metastatic therapy. However, the expression profiles, prognostic relevance, and diagnostic value of its subunits across cancers remain poorly understood. This study aims to investigate the clinical relevance of Arp2/3 complex subunits, particularly ARPC1A, in pan-cancer, and to further analyze the potential biological mechanisms of ARPC1A, as well as its association with immune infiltration and chemotherapy drug sensitivity.

When juxtaposed with 2D cell culture models, multicellular tumor spheroids demonstrate a capacity to faithfully replicate certain features inherent to solid tumors. These include spatial architecture, physiological responses, the release of soluble mediators, patterns of gene expression, and mechanisms of drug resistance. The morphological and behavioural similarities between 3D-cultured cells and cells within tumor masses highlight the potential of these models in studying cancer biology and drug responses.
