This paper investigates the healthcare needs, access to healthcare, and healthcare strategies of Ethiopian migrant domestic workers (MDWs) in Lebanon, drawing on qualitative empirical research. The analysis focusses on four types of health care needs: minor illnesses, pregnancies, serious illnesses (such as cancer, tuberculosis or heart problems), and emergencies (due to accidents, suicide attempts or assaults). Predictably, access to healthcare is distinctly differentiated according to an MDW's status as a documented, freelancer, or undocumented worker...

Prevalence of zoonotic Mycobacterium bovis (bTB) disease in human population is underreported from the North of Pakistan. Here, we report on the proportion of human bTB disease among the overall TB patients, drug resistance pattern of bTB isolates, and knowledge, attitude, and practices (KAP)-based analysis of bTB disease. For this purpose, sputum samples from a total of 300 clinically diagnosed TB patients and 100 randomly selected school children suspected of pulmonary TB were processed by culture as well as polymerase chain reaction (PCR) for isolation, identification, and confirmation of Mycobacterium tuberculosis (mTB) and bTB species...

The scale-up of rapid drug resistance testing for TB is a global priority. MTBDRplus is a WHO-endorsed multidrug-resistant (MDR)-TB PCR assay with suboptimal sensitivities and high indeterminate rates on smear-negative specimens. We hypothesised that widespread use of incorrect thermocycler ramp rate (speed of temperature change between cycles) impacts performance. A global sample of 72 laboratories was surveyed. We tested 107 sputa from Xpert MTB/RIF-positive patients and, separately, dilution series of bacilli, both at the manufacturer-recommended ramp rate (2...

Mycobacterium tuberculosis, the etiological agent of the infectious disease tuberculosis, kills approximately 1.5 million people annually, while the spread of multidrug-resistant strains is of great global concern. Thus, continuous efforts to identify new antitubercular drugs as well as novel targets are crucial. Recently, two prodrugs activated by the monooxygenase EthA, 7947882 and 7904688, which target the CTP synthetase PyrG, were identified and characterized. In this work, microbiological, biochemical, and in silico methodologies were used to demonstrate that both prodrugs possess a second target, the pantothenate kinase PanK...

The ability of Mycobacterium tuberculosis to block host antimicrobial responses in infected cells provides a key mechanism for disease pathogenesis. The immune system has evolved to overcome this blockade to restrict the infection, but it is not clear whether two key innate cytokines (IL-12/IL-18) involved in host defense can enhance antimycobacterial mechanisms. In this study, we demonstrated that the combination of IL-12 and IL-18 triggered an antimicrobial response against mycobacteria in infected macrophages (THP-1 and human primary monocyte-derived macrophages) and pulmonary epithelial A549 cells...

Euphorbia ebracteolata was a natural medicine for the treatment of tuberculosis. The present work has performed the investigation of bioactive chemical substances from the roots of E. ebracteolata. Using various chromatographic techniques, 15 compounds were obtained from the roots of E. ebracteolata. On the basis of widely spectroscopic data analyses, the isolated compounds were determined to be diterpenoids, including rosane derivatives (1-12), isopimarane (13), abietane (14), and lathyrane (15), among which compounds 1-4, and 9 were undescribed previously...

BACKGROUND: Bedaquiline and delamanid have been approved for treatment of multidrug-resistant (MDR) tuberculosis in the past 5 years. Because of theoretical safety concerns, patients have been unable to access the two drugs in combination. Médecins Sans Frontières has supported the use of combination bedaquiline and delamanid for people with few treatment options since 2016. We describe early safety and efficacy of regimens containing the bedaquiline and delamanid combination in patients with drug-resistant tuberculosis in Yerevan, Armenia; Mumbai, India; and Khayelitsha, South Africa...

Communication technologies have invaded our daily lives. Several studies have assessed these technologies in the management of infectious diseases (mainly HIV). Weekly short text messages and real-time compliance monitoring assessed in HIV patients are both associated with higher compliance in low-income countries. Virtual consultations to monitor stable chronic HIV patients or tuberculosis treatment in high-income countries appear to be acceptable and efficient. Although assessed in small studies, virtual monitoring seems to reinforce the doctor-patient relationship and the relation between primary care settings and hospitals in various infectious diseases (endocarditis, urinary tract infection, skin and soft tissue infection, HIV, tuberculosis, hepatitis C)...

Monitoring response to treatment is a key element in the management of infectious diseases, yet controversies still persist on reliable biomarkers for noninvasive response evaluation. Considering the limitations of invasiveness of most diagnostic procedures and the issue of expression heterogeneity of pathology, molecular imaging is better able to assay in vivo biologic processes noninvasively and quantitatively. The usefulness of 18 F-FDG-PET/CT in assessing treatment response in infectious diseases is more promising than for conventional imaging...

Tuberculosis (TB) is currently the world's leading cause of infectious mortality. Imaging plays an important role in the management of this disease. The complex immune response of the human body to Mycobacterium tuberculosis results in a wide array of clinical manifestations, making clinical and radiological diagnosis challenging. 18 F-FDG-PET/CT is very sensitive in the early detection of TB in most parts of the body; however, the lack of specificity is a major limitation. 18 F-FDG-PET/CT images the whole body and provides a pre-therapeutic metabolic map of the infection, enabling clinicians to accurately assess the burden of disease...

Evidence to-date collectively points to a detrimental role of the type I IFN response during tuberculosis. The mechanisms underpinning the IFNαβ-mediated exacerbation of the disease is unclear. The 2'-5'-oligoadenylate synthetases (OAS), namely OAS1, OAS2 and OAS3 are part of the interferon-induced genes which until now have been synonymous with an anti-viral function. Blood transcriptome profiling has continuously observed their upregulation in a number of gene expression signatures which discriminate active TB from latent TB infection, however the role of the OASs and the effect that their expression has on the pathogenesis and persistence of TB is unknown...

Although the tuberculin test represents the main in vivo diagnostic method used in the control and eradication of bovine tuberculosis, few studies have focused on the identification of mycobacteria in the milk from cows positive to the tuberculin test. The aim of this study was to identify Mycobacterium species in milk samples from cows positive to the comparative intradermal test. Milk samples from 142 cows positive to the comparative intradermal test carried out in 4,766 animals were aseptically collected, cultivated on Lowenstein-Jensen and Stonebrink media and incubated for up to 90 days...

For many years, tuberculosis (TB) has been endemic in Pakistan; many rare and unusual presentations have been reported. There is a myriad of non-specific symptoms which always requires a high index of clinical suspicion for TB. World Health Organization data suggest that Pakistan ranks as the fifth highest country burdened with TB and has the fourth highest prevalence of multi-drug resistant TB globally. With an annual incidence of 277 cases per 100,000, the importance of early diagnosis and treatment is self-evident...

Nonomuraea rhodomycinica NR4-ASC07 T is a rare actinomycete isolated from soil in Sirindhorn peat swamp forest. The crude extract of its culture broth exhibited antimicrobial and anticancer against diverse human pathogens and cancer cells. The chemical investigation of the crude extract led to the isolation of two new metabolites named nonomuric acid (1) and 3-hydroxy deoxydaunorubicinol aglycone (2), along with two known bioactive compounds [ε-rhodomycinone (3) and 7-deoxy-13-dihydrocarminomycinone (4)]. Compounds 1 and 3 showed antimalarial activity with the half maximal inhibitory concentration (IC 50 ) of 8...

We present the case of a patient who was diagnosed by chance with macular hypopyon during a conventional interdisciplinary examination. The clinical context and the association of a systemic disease, such as uncontrolled type 1 diabetes, rendered further investigations in this patient. Due to his immunocompromised status, etiology such as ocular fungi, lymphomas, tuberculosis was taken into account. Thorough complex investigations oriented the diagnosis towards ocular tuberculosis involvement.

Bronchial stenosis is known to complicate endobronchial tuberculosis despite medical therapy. It is often associated with dyspnoea. In severe cases, bronchial stenosis results in airflow obstruction, impaired secretion clearance, and can lead to respiratory failure. We present an unusual observation of platypnoea-orthodeoxia syndrome in a young woman with acute atelectasis due to post-tuberculosis bronchial stricture. Imaging revealed complete middle and right lower lobe atelectasis with a partially aerated right upper lobe...
