Prevalence of non-tuberculous mycobacteria among people with acid-fast positive presumptive tuberculosis in Mali.

Background: Non-tuberculous mycobacteria (NTM) are environmental agents that can cause opportunistic pulmonary disease in humans and animals, often misdiagnosed as tuberculosis (TB). In this study, we describe the cases of NTM identified during the first national anti-TB drug resistance survey conducted in Mali and explore associated risk factors.

Methods: Sputum was collected from people presenting for pulmonary TB diagnosis from April to December 2019, regardless of age.

High Schistosoma mansoni Co-Infection in Tuberculosis Patients with or without Human Immunodeficiency Virus: A Prospective Cohort Study.

Background: People with Latent tuberculosis infection (LTBI) remain the reservoir of tuberculosis. One-third to 1/4 of the world's population is infected. Its reactivation is due to factors that disrupt the host's immune response.

Comparing vaccination coverage before and during COVID-19 pandemic in children under one year in the health district of commune V in Bamako, Mali.

Introduction: Although an essential frontline service in the prevention of child morbidity and mortality, there are indications that routine vaccinations have been disrupted during the COVID-19 pandemic. The present study aimed to compare vaccination coverage before COVID-19 in Mali in 2019 and during COVID-19 in 2020.

Objective: To compare vaccination coverages before COVID-19 in Mali in 2019 and during COVID-19 in 2020.

Relationship between patient sex and anatomical sites of extrapulmonary tuberculosis in Mali.

Background: Contribution of host factors in mediating susceptibility to extrapulmonary tuberculosis is not well understood.

Objective: To examine the influence of patient sex on anatomical localization of extrapulmonary tuberculosis.

Methods: We conducted a retrospective cross-sectional study in Mali, West Africa.

Prevalence and Clinical Relevance of Co-Infection with : A Systematic Literature Review.

Tuberculosis disease stands for the second leading cause of death worldwide after COVID-19, most active tuberculosis cases result from the reactivation of latent TB infection through impairment of immune response. Several factors are known to sustain that process. , a parasite of the helminth genus that possesses switching power from an immune profile type Th1 to Th2 that favors reactivation of latent TB bacteria.

Identifying Risk Factors for Pulmonary Tuberculosis Diagnosis Delays in Mali a West-African Endemic Country.

Background: Tuberculosis was the deadliest infectious agent before covid-19; 1.5 million deaths in 2020. Despite, a variety, of easy and cheap diagnostic tools, detection rates still fall below 90%; diagnosis delays are long exceeding 30 days in many continents.

Sex Differences in Active Pulmonary Tuberculosis Outcomes in Mali, West Africa.

Men and women often respond differently to infectious diseases and their treatments. Tuberculosis (TB) is a life-threatening communicable disease that affects more men than women globally. Whether male sex is an independent risk factor for unfavorable TB outcomes, however, has not been rigorously investigated in an African context, where individuals are likely exposed to different microbial and environmental factors.

Incidence and Predictors of Imported Cases of COVID-19 in Burkina Faso.

Background: To limit the spread of COVID-19 due to imported cases, Burkina Faso has set up quarantine measures for arriving passengers. We aimed to determine the incidence and predictors of imported cases of COVID-19 in Burkina Faso.

Methods: A prospective cohort study was performed using data from passengers arriving at the airport from April 9 to August 31, 2020.

[Relationship between occupational exposure of waste manipulators of electrical and electronic equipment and respiratory problems in Bamako in 2019].

Introduction: waste electrical and electronic equipment (WEEE), with its health and environmental issues, has become a public health problem exposing workers to toxic compounds causing respiratory problems.

Objective: To study the relationship between professional exposure to WEEE and the occurrence of respiratory problems in Bamako in 2019.

Material And Methods: This was a 6-month cross-sectional, analytical study carried out in the city of Bamako in 2019 and involved 159 WEEE manipulators.

Antituberculosis Therapy and Gut Microbiota: Review of Potential Host Microbiota Directed-Therapies.

Tuberculosis (TB) remains a major public health concern with millions of deaths every year. The overlap with HIV infections, long treatment duration, and the emergence of drug resistance are significant obstacles to the control of the disease. Indeed, the standard first-line regimen TB treatment takes at least six months and even longer for the second-line therapy, resulting in relapses, drug resistance and re-infections.

Development and clinical evaluation of a new multiplex PCR assay for a simultaneous diagnosis of tuberculous and nontuberculous mycobacteria.

Background: The prevalence of non-tuberculous mycobacteria (NTM) has been increasing worldwide in both developed and developing countries. NTM infection is clinically indistinguishable from tuberculosis and therefore poses significant challenges in patient management, especially in patients chronically treated for pulmonary TB. In this study, we evaluated a new highly sensitive Multiplex MTB/NTM assay that can differentiate M.

[Gastrointestinal symptoms revealing COVID-19 in Malian breast cancer patient undergoing chemotherapy].

In this review, we report a case of a bone's metastatic breast cancer in Malian patient treated by chemotherapy in whom SRAS-COV-2's diagnosis was made 9days after the onset gastrointestinal symptoms. Patient quickly died before any COVID-19's treatment. According to the poor outcomes of cancer patients with COVID-19, authors emphasize to an intensive attention to such patients in order to find the best therapeutic balance between the two pathologies during this pandemic.

Indoor exposure to particulate matter and volatile organic compounds in dwellings and workplaces and respiratory health in French farmers.

Introduction: Few investigations have related objective assessments of indoor air pollutants to respiratory health in farmers, in spite of the many rural environmental hazards to which they are exposed. Chemical air pollution has been particularly neglected.

Objective: We investigated the relationships of indoor exposure to particulate matter (PM) and volatile organic compounds (VOCs) to respiratory health in farmers.

Clinical risk factors associated with multidrug-resistant tuberculosis (MDR-TB) in Mali.

Background: MDR-TB is a major threat to global TB control. In 2015, 580,000 were treated for MDR-TB worldwide. The worldwide roll-out of GeneXpert MTB/RIF has improved diagnosis of MDR-TB; however, in many countries laboratories are unable to assess drug resistance and clinical predictors of MDR-TB could help target suspected patients.

The most frequent complex families in mali (2006-2016) based on spoligotyping.

Background: To identify strains of Mycobacterium tuberculosis complex (MTBc) circulating in Bamako region during the past 10 years.

Methods: From 2006 to 2016, we conducted a cross-sectional study to identify with spoligotyping, clinical isolates from tuberculosis (TB)-infected patients at different stages of their treatments in Bamako, Mali.
