Effective tuberculosis (TB) prevention and care for migrants requires population health-based approaches that treat the relationship between migration and health as a progressive, interactive process influenced by many variables and addressed as far upstream in the process as possible. By including capacity building in source countries, pre-migration medical screening has the potential to become an integral component of public health promotion, as well as infection and disease prevention, in migrant-receiving nations, while simultaneously increasing capabilities in countries of origin...

Background: Multidrug-resistant tuberculosis (MDR TB) is an important global public health threat, but accurate estimates of MDR TB burden among children are lacking. Methods: We analyzed demographic, clinical and laboratory data for newly-diagnosed pediatric (<15 years) TB cases reported to the US National TB Surveillance System (NTSS) during 1993-2014. MDR TB was defined as culture-confirmed TB disease with resistance to at least isoniazid and rifampicin. To ascertain potential under-estimation of pediatric MDR TB, we surveyed high burden states for clinically-diagnosed cases treated for MDR TB...

At present, three rapid kits are available globally for the confirmation of Mycobacterium tuberculosis complex (MTBC) in cultures by MPT64 antigen (MPT64 Ag) detection. These include Capilia TB, SD Bioline, and BD MGIT TBc Identification (TBcID). The third kit is yet to be validated in India. We have tested this kit and compared with SD Bioline using conventional tests as gold standard. Seventy-one MTBC (70 M. tuberculosis and one Mycobacterium bovis) and four nontuberculous mycobacteria (NTM) were isolated from 649 clinical specimens in MGIT 960 and/or Lowenstein-Jensen slants (LJ)...

China has the world's second largest burden of multidrug-resistant tuberculosis (MDR-TB; resistance to at least isoniazid and rifampicin), with an estimated 57,000 cases (range, 48,000-67,000) among notified pulmonary TB patients in 2015. During October 1, 2006-June 30, 2014, China expanded MDR-TB care through a partnership with the Global Fund to Fight AIDS, Tuberculosis, and Malaria (Global Fund). We analyzed data on site expansion, patient enrolment, treatment outcomes, cost per patient, and overall programme expenditure...

Tuberculosis continues to be one of the most important infectious causes of death worldwide. Despite substantial investments and progress made in expansion of directly observed therapy short course (DOTS) strategy, improved treatment completion rates and inadequate case detection remains a major obstacle for global control of Tuberculosis. The global case detection rate has increased from 28% to 60%. However, it is estimated that approximately 50% of patients with tuberculosis are still not diagnosed or treated appropriately...

Tuberculosis (TB) is a serious global health problem, although it is easily preventable and curable. The prevalence of TB is caused by a lack of simple, rapid, cheap, and effective TB diagnostic tests. In this study, we have established a novel liquid crystal (LC)-based immunosensor to diagnose TB in clinical specimens. The clinical serum samples were incubated on a TB antigen-immobilized substrate, and their optical LC responses were observed using a polarized light microscope. Specific binding of anti-TB antibodies to the TB antigen-immobilized surface only occurred in clinical specimens from TB patients, inducing the disruption of the orientation of LCs...

The global tuberculosis (TB) incidence estimated by WHO is found to be 8.6 million people. Moreover, the highest TB burden worldwide is found in Asian and African countries. The disease is more prevalent in infants due to their immature immune systems. Despite this, the available diagnostic tools pose a challenge due to paucibacillary nature of the disease and difficulty in obtaining specimens. The present review article discusses the important and upcoming advancements in the management of above pathological state...

BACKGROUND: A recent randomized trial (NCT01535209) demonstrated no difference in neurocognitive function between stereotactic radiotherapy of the tumor bed (SRT-TB) and whole brain radiotherapy (WBRT) in patients with resected single brain metastasis. Patients treated with SRT-TB had lower overall survival compared with the WBRT arm. Here, we compared the health-related quality of life (HRQOL) in patients who received WBRT vs. SRT-TB. METHODS: A self-reported questionnaire was used to assess HRQOL (EORTC QLQ-C30 with the QLQ-BN20 module) before RT, 2 months after RT, and every 3 months thereafter...

The most recent estimates on tuberculosis (TB) morbidity and mortality reveal that the global disease burden is even higher than previously assumed. Better drugs, diagnostics and vaccines are major requirements to control the ongoing TB pandemic. The high complexity of the infectious process and the underlying pathology, however, challenge elucidation of protective immune mechanisms at the various stages towards active TB disease, which need to be understood for rational design of novel intervention measures...

BACKGROUND: Extensively drug-resistant (XDR) tuberculosis (TB) and multidrug resistant (MDR)-TB with additional resistance to injectable agents or fluoroquinolones are challenging to treat due to lack of available, effective drugs. Linezolid is one of the few drugs that has shown promise in treating these conditions. Long-term linezolid use is associated with toxicities such as peripheral and optic neuropathies. Diabetes mellitus (DM), especially when uncontrolled, can also result in peripheral neuropathy...

INTRODUCTION: Diabetes mellitus (DM) is an important risk factor for active tuberculosis (TB), which also adversely affect TB treatment outcomes. The escalating global DM epidemic is fuelling the burden of TB and should therefore be a major target in the strategy for ending TB. This review aims to estimate the global prevalence of DM in patients with TB. METHODS AND ANALYSIS: This systematic review will include cross-sectional, case-control or cohort studies of populations including patients diagnosed with TB that have reported the prevalence of DM using one of the fourth standard recommendations for screening and diagnosis...

BACKGROUND: Tuberculosis (TB) is the deadliest infectious disease globally, with 10.4 million people infected and more than 1.8 million deaths in 2015. TB is a preventable, treatable, and curable disease, yet there are numerous barriers to initiating treatment. These barriers to treatment are exacerbated in low-resource settings and may be compounded by factors related to childhood. OBJECTIVE: Timely initiation of tuberculosis (TB) treatment is critical to reducing disease transmission and improving patient outcomes...

Spatiotemporal analysis is an important tool to monitor changes of tuberculosis (TB) epidemiology, identify high-risk regions and guide resource allocation. However, there are limited data on the contributing factors of TB incidence. This study aimed to investigate the spatiotemporal pattern of TB incidence and its associated factors in mainland China during 2005-2013. Global Moran's I test, Getis-Ord Gi index and heat maps were used to examine the spatial clustering and seasonal patterns. Generalized Linear Mixed Model was applied to identify factors associated with TB incidence...

We recently found that the mRNA expression of Slc25a25, a Ca(2+)-sensitive ATP carrier in the inner mitochondrial membrane, fluctuates in a circadian manner in mouse skeletal muscle. We showed here that the circadian expression of muscle Slc25a25 was damped in Clock mutant, muscle-specific Bmal1-deficient, and global Bmal1-deficient mice. Furthermore, a ketogenic diet (KD) that induces time-of-day-dependent hypothermia (torpor), induced Slc25a25 mRNA expression in skeletal muscle. Hypothermia induced by KD did not affect thermogenic genes such as Sarcolipin and Pgc1a in muscles and Ucp1 in adipose tissues...

Antimicrobial resistance has become a global problem. Many pathogens are becoming multidrug-resistant with the attendant increased risk of failure of standard therapies and the under-recognised outcomes such as increased morbidity, mortality, length of hospitalization and costs of treatment. Areas covered: We undertook a review of the literature using standard search engines including PubMed, Google Scholar, Scopus and internet sources. Key search terms included antimicrobial resistance, antibiotic resistance, bacterial resistance, clinical outcomes, economic consequences, Escherichia coli, Pseudomonas aeruginosa, Klebsiella pneumoniae, Streptococcus pneumoniae and Staphylococcus aureus...

Tuberculosis remains a global pandemic and drives lung matrix destruction to transmit. Whilst pathways driving inflammatory responses in macrophages have been relatively well described, negative regulatory pathways are less well defined. We hypothesised that Mycobacterium tuberculosis (Mtb) specifically targets negative regulatory pathways to augment immunopathology. Inhibition of signalling through the PI3K/AKT/mTORC1 pathway increased matrix metalloproteinase-1 (MMP-1) gene expression and secretion, a collagenase central to TB pathogenesis, and multiple pro-inflammatory cytokines...

PURPOSE OF REVIEW: Antiretroviral (ARV) therapy costs in low-income and middle-income countries are major concerns, and lower doses of first-line treatment components, when possible, would save millions of dollars, which could be used to treat more people living with HIV. RECENT FINDINGS: The Encore-1 study, followed by a detailed pharmacokinetic analysis of efavirenz 400 versus 600 mg once daily, produced enough information for the most recent ARV treatment WHO guidelines to include efavirenz 400 mg among agents used for first-line treatment...

With the rapid pace of population ageing, tuberculosis (TB) in the elderly increasingly becomes a public health challenge. Despite the increasing burden and high risks for TB in the elderly, targeted strategy has not been well understood and evaluated. We undertook a scoping review to identify current TB strategies, research and policy gaps in the elderly and summarized the results within a strategic framework towards End TB targets. Databases of Embase, MEDLINE, Global health and EBM reviews were searched for original studies, review articles, and policy papers published in English between January 1990 and December 2015...
