Tuberculosis patients face high treatment support costs in Colombia, 2021.

Objective: To estimate the baseline to measure one of the three indicators of the World Health Organization (WHO) End TB strategy (2015-2035), measure the costs incurred by patients affected by tuberculosis (TB) during a treatment episode and estimate the proportion of households facing catastrophic costs (CC) and associated risk factors, in Colombia, 2021.

Material And Methods: A nationally representative cross-sectional survey was conducted among participants on TB treatment in Colombia, using telephone interviews due to the exceptional context of the COVID-19 pandemic. The survey collected household costs (direct [medical and non-medical out-of-pocket expenses] and indirect) over an episode of TB, loss of time, coping measures, self-reported income, and asset ownership.

Tuberculosis multirresistente en Colombia, 2013-2018: estudio de casos y controles.

Introduction: Multidrug-resistant/rifampicin-resistant tuberculosis (MDR/RR-TB) is difficult to control, has high morbidity and mortality, and demands priority public health intervention. In Colombia, MDR/RR-TB has been becoming more widespread annually. Before the COVID-19 pandemic, over an 8-year period, the number of cases of multidrug-resistant tuberculosis in Colombia was close to a thousand cases.

Infections in patients with adverse reactions to the use of unknown modeling substances for soft tissue enhancement in Cali, Colombia.

The infiltration of foreign materials not approved for medical purposes or of modeling substances used in soft tissue to modify the anatomical appearance for aesthetic purposes represents a serious health problem. These procedures lead to the development of delayed complications, including infections. The objective of this study was to characterize infections in patients with adverse reactions to the use of modeling substances in Cali, Colombia.

Synthesis, Anticancer and Antitubercular Properties of New Chalcones and Their Nitrogen-Containing Five-Membered Heterocyclic Hybrids Bearing Sulfonamide Moiety.

A new series of sulfonamides, , and , were synthesized by -sulfonation reaction with sulfonyl chlorides . Five new series of chalcone-sulfonamide hybrids were prepared via Claisen-Schmidt condensation of the newly obtained sulfonamides with aromatic aldehydes in basic medium. Chalcones substituted with chlorine at position 4 of each series were used as precursors for the generation of their five-membered heterocyclic pyrazoline (, () and carbothioamide derivatives.

[National Network for Knowledge Management, Research, and Innovation in Tuberculosis in ColombiaRede Nacional de Gestão do Conhecimento, Pesquisa e Inovação em tuberculose na Colômbia].

In 2018, the Colombian Ministry of Health and Social Protection, in collaboration with the National Health Institute and the Pan American Health Organization, convened all actors associated with the National Tuberculosis Prevention and Control Program (PNPCT) and the National Science, Technology, and Innovation System to form a national network to coordinate operations research on tuberculosis (TB) in the country. Seven workshops were held and a consensus was reached to establish the National Network for Knowledge Management, Research, and Innovation in Tuberculosis in Colombia (TB Colombia Network). With more than 180 participants, a central node, and five regional nodes that bring together the country's 37 territorial entities, the TB Colombia Network conducted four days of training in operations research in 2019, defining 65 priority research topics aligned with the strategic lines in the PNPCT: prevention and comprehensive care, with a focus on people affected by TB (41 topics in three modules); and political commitment, social protection, and support systems (24 topics in four modules).

Antimicrobial Activity of Quinoline-Based Hydroxyimidazolium Hybrids.

Eight quinoline-based hydroxyimidazolium hybrids were prepared and evaluated in vitro against a panel of clinically important fungal and bacterial pathogens, including mycobacteria. Hybrid compounds showed remarkable antifungal activity against with a minimum inhibitory concentration (MIC) value of 15.6 µg/mL.

Characterization of clinical isolates of Mycobacterium tuberculosis from indigenous peoples of Colombia.

Introduction: Tuberculosis continues to be a public health priority. Indigenous peoples are vulnerable groups with cultural determinants that increase the risk of the disease.

Objective: To determine molecular epidemiology and phenotypical features and of Mycobacterium tuberculosis isolates from indigenous people in Colombia during the period from 2009 to 2014.

New chalcone-sulfonamide hybrids exhibiting anticancer and antituberculosis activity.

New sulfonamides 5/6 derived from 4-methoxyacetophenone 1 were synthesized by N-sulfonation reaction of ammonia (3) and aminopyrimidinone (4) with its sulfonyl chloride derivative 2. Sulfonamides 5 and 6 were used as precursors of two new series of chalcones 8a-f and 9a-f, which were obtained through Claisen-Schmidt condensation with aromatic aldehydes 7a-f. Compounds 5/6, 8a-d, 8f, 9a-d, and 9f were screened by the US National Cancer Institute (NCI) at 10 μM against sixty different human cancer cell lines (one-dose trial).

Diarylethenes Display In Vitro Anti-TB Activity and Are Efficient Hits Targeting the Mycobacterium tuberculosis HU Protein.

Tuberculosis continues to be a great source of concern in global health because of the large reservoir of humans infected with the bacilli and the appearance of clinical isolates resistant to a wide array of anti-tuberculosis drugs. New drugs with novel mechanisms of action on new targets are urgently required to reduce global tuberculosis burden. nucleoid associated protein (NAP) HU has been shown to be druggable and essential for the organism's survival.

[Characterization of clinical isolates of Mycobacterium tuberculosis from HIV positive individuals in Colombia, 2012].

Introduction: One third of the increase in tuberculosis cases is attributed to the spread of HIV. In 2012, 1,397 HIV-associated tuberculosis cases were reported in Colombia, i.e.

Mycobacterium tuberculosis Genotypes Determined by Spoligotyping to Be Circulating in Colombia between 1999 and 2012 and Their Possible Associations with Transmission and Susceptibility to First-Line Drugs.

Biosafety evaluation of the DNA extraction protocol for Mycobacterium tuberculosis complex species, as implemented at the Instituto Nacional de Salud, Colombia.

Introduction: Manipulating Mycobacterium tuberculosis clinical specimens and cultures represents a risk factor for laboratory personnel. One of the processes that requires high concentrations of microorganisms is DNA extraction for molecular procedures. Pulmonary tuberculosis cases have occurred among professionals in charge of molecular procedures that require manipulation of massive quantities of microorganisms.

[Molecular identification of non-tuberculous mycobacteria].

Introduction: Nontuberculous mycobacteria can be saprophytic, pathogenic or opportunistic. The most common diseases produced by these microorganisms are the post-surgical infections due to anesthetic procedures, infections associated with catheters, disseminated cutaneous diseases and pulmonary and central nervous system diseases that especially affect HIV patients. Identification of the nontuberculous mycobacteria can take several weeks and even then, differentiation of complex members is not possible.
