Spatial analysis of tuberculosis and its relationship with socioeconomic indicators in a medium-sized city in Minas Gerais

Conclusion: The dynamics of tuberculosis transmission in Juiz de Fora may be explained by the maintenance of social inequality and urban space organization process.RESUMO: Objetivo: Analisar o padr ão espacial da tuberculose e sua relação com indicadores socioeconômicos, entre 2008 e 2015, em um município considerado prioritário para o controle da tuberculose pelo Programa Nacional de Controle da Tuberculose, Juiz de Fora (MG). Métodos: Estudo ecológico no qual as unidades de análise foram as 81 regiões urbanas de Juiz de Fora. Foram usados dados secundários a partir do banco de dados de notificação do Sistema de Informação de Agravos de Notificação e dados do Censo Demográfico de 2010. Foram georreferenciadas 1.854 notificações e elaborados mapas temáticos para ver ificar o padrão da distribuição da taxa média de incidência de tuberculose e de indicadores socioeconômicos no município. Foram estimadas medidas de autocorrelação espacial global (coeficiente I de Moran) e local (Indicador Local de Associação Espacial) e modelo de regressão linear múlt ipla para verificar a relação entre a taxa média de incidência de tuberculose e os indicadores socioeconômicos. Resultados: A taxa média de incidência de ...

Immunometabolism is a burgeoning field of investigation in tuberculosis host defense, susceptibility, and pathophysiology. Unbiased approaches to studying tuberculosis have, as expected, confirmed that pathways of immunometabolism are crucial in these disease processes. In this issue of the JCI, Reichmann et al. studied carefully controlled human lymph node tuberculosis and uncovered Sphingosine kinase 1 as a druggable target of interest that could support the infected host. Future host-directed therapy research might seek to establish the different cellular consequences of sphingolipid pathway manipulation. Animal models ...

CONCLUSION Adjunctive doxycycline with standard anti-TB treatment suppressed pathological MMPs in PTB patients. Larger studies on adjunctive doxycycline to limit TB immunopathology are merited.TRIAL REGISTRATION NCT02774993.FUNDING Singapore National Medical Research Council (NMRC/CNIG/1120/2014, NMRC/Seedfunding/0010/2014, NMRC/CISSP/2015/009a); the Singapore Infectious Diseases Initiative (SIDI/2013/013); National University Health System (PFFR-28 January 14, NUHSRO/2014/039/BSL3-SeedFunding/Jul/01); the Singapore Immunology Network Immunomonitoring platform (BMRC/IAF/311006, H16/99/b0/011, NRF2017_SIS...

Pulmonary cavitation is a hallmark of Mycobacterium tuberculosis (Mtb) infection that provides an immune-privileged niche for extracellular bacillary replication, which associates with increased transmission rates, drug resistance, and chronic lung dysfunction following antituberculous therapy (ATT). Inhibitors of matrix metalloproteinases (MMPs), which are induced by Mtb infection, have shown efficacy in preclinical models and improved microbiologic and immunopathologic outcomes. In this issue of the JCI, Hao Miow et al. performed a double-blind, randomized controlled trial exploring host-directed effects of the MMP inhib...

This study was aimed at exploring whether latent tuberculosis infection (LTBI) contributes to the pathogenesis of immune-mediated inflammatory diseases in a TB endemic setting. We screened 198 rheumatoid arthritis (RA) patients with tuberculin skin test (TST) and studied 61 (median DAS28-ESR = 6.3 ) who were positive. Whole blood T cell proliferative responses toMycobacterium tuberculosis (Mtb) membrane (MtM) antigens, including the latency-induced protein alpha crystallin (Acr), were determined by flow cytometry using Ki67 expression as the marker for nuclear proliferation. Serum antibody levels were determined by ELISA. ...

Tuberculosis (TB) is a chronic infectious disease mainly caused by Mycobacterium tuberculosis (MTB), but other members of the Mycobacterium tuberculosis complex (MTBC), especially Mycobacterium bovis (pyrazinamide-resistant organisms), may also be involved. Thus, the ability to rapidly detect and identify MTB from other MTBC members (e.g., M. bovis, Mycobacterium microti, Mycobacterium africanum) is essential for the prevention and treatment of TB. A novel diagnostic method for the rapid detection and differentiation of MTB, which employs multiplex loop-mediated isothermal amplification (mLAMP) combined with a nanoparticle...

The patient is a 51-year-old  male from Mexico with no known significant past medical history who presented with several weeks of intermittent fevers, chills, night sweats, headaches and weight loss. Two months prior to this admission, headaches, fevers, chills and night sweats had begun. One week prior to this admission he had presented to another institution with a chief complaint of persistent headaches. At the outside hospital the patient was found to have a positive Quantiferon Gold test. An Acid-Fast Bacilli (AFB) smear collected from the sputum at that institution was negative and culture remained negative after 1 week.

CONCLUSIONS: Decreased T lymphocytes in APTB patients may cause compensatory activation of CD8+ T cells. Multifunctional CD4+ T cells in peripheral blood could migrate to the lungs under the action of CXCR3 and associated chemokine. Multifunctional CD4+ T cells and Multifunctional CD8+ T cells were of great significance in monitoring disease treatment.PMID:34333359 | DOI:10.1016/j.intimp.2021.107898

The SARS CoV-2 is a RNA virus belonging to the family coronaviridae. It has high infectivity. The manifestations of the disease range from asymptomatic or mild symptoms to severe pneumonia and ARDS. The CT scan of lung shows consolidation and "Ground Glass Opacities". The persons with other comorbidities are considered to be at a higher rate of acquiring the infection.
