Stroke remains a major public health problem worldwide; it causes severe disability and is associated with high mortality rates. However, early diagnosis of stroke is difficult, and no reliable biomarkers are currently established. In this study, mass spectrometry-based metabolomics was utilized to characterize the metabolic features of the serum of patients with acute ischemic stroke (AIS) to identify novel sensitive biomarkers for diagnosis and progression. First, global metabolic profiling was performed on a training set of 80 human serum samples (40 cases and 40 controls)...

Fungi cause more than a billion skin infections, more than 100 million mucosal infections, 10 million serious allergies and more than a million deaths each year. Global mortality owing to fungal infections is greater than for malaria and breast cancer and is equivalent to that owing to tuberculosis (TB) and HIV. These statistics evidence fungal infections as a major threat to human health and a major burden to healthcare budgets worldwide. Those patients who are at greatest risk of life-threatening fungal infections include those who have weakened immunity or have suffered trauma or other predisposing infections such as HIV...

PURPOSE OF REVIEW: Recent advances in point-of-care technologies to ensure universal access to affordable quality-assured diagnostics have the potential to transform patient management, surveillance programmes, and control of infectious diseases. Decentralization of testing can put tremendous stresses on fragile health systems if the laboratory is not involved in the planning, introduction, and scale-up strategies. RECENT FINDINGS: The impact of investments in novel technologies can only be realized if these tests are evaluated, adopted, and scaled up within the healthcare system with appropriate planning and understanding of the local contexts in which these technologies will be used...

The emergence of antimicrobial resistance (AMR) is a major concern worldwide and already compromises treatment effectiveness and control of several bacterial sexually transmitted infections (STIs). Neisseria gonorrhoeae and Mycoplasma genitalium are evolving into so-called superbugs that can become resistant, both in vitro and clinically, to essentially all antimicrobials available for treatment, causing exceedingly difficult-to-treat or untreatable STIs and threatening global public health. Widespread AMR in these bacteria is likely to persist and even worsen in the future, owing to the high number of infections, widespread and uncontrolled use of antimicrobials, limited surveillance of AMR and clinical failures, as well as the extraordinary capacity of these bacteria to develop AMR...

BACKGROUND: Though many countries, including China, are moving towards malaria elimination, malaria remains a major global health threat. Due to the spread of antimalarial drug resistance and the need for innovative medical products during the elimination phase, further research and development (R&D) of innovative tools in both epidemic and elimination areas is needed. This study aims to identify the trends and gaps in malaria R&D in China, and aims to offer suggestions on how China can be more effectively involved in global malaria R&D...

Gestational diabetes mellitus (GDM) is currently defined as glucose intolerance that is of variable severity with onset or first recognition during pregnancy. The Hyperglycemia and Adverse Pregnancy Outcome Study, including 25 000 nondiabetic pregnant women in 15 centers across the world, reported that an average of 17.8% of pregnancies are affected by GDM and its frequency can be as high as 25.5% in some countries, based on the International Association of Diabetes and Pregnancy Study Groups criteria. Nevertheless, true global prevalence estimates of GDM are currently lacking due to the high level of heterogeneity in screening approaches, diagnostic criteria, and differences in the characteristics of the populations that were studied...

BACKGROUND: Human resource for health crisis has impaired global efforts against malaria in highly endemic countries. To address this, the World Health Organization (WHO) recommended scaling-up of community health workers (CHWs) and related cadres owing to their documented success in malaria and other disease prevention and management. Evidence is inconsistent on the roles and challenges they encounter in malaria interventions. This systematic review aims to summarize evidence on roles and challenges of CHWs and related cadres in integrated community case management for malaria (iCCM)...

The larva of cestodes belonging to the Echinococcus granulosus sensu lato (s.l.) complex causes cystic echinococcosis (CE). It is a globally distributed zoonosis with significant economic and public health impact. The most immunogenic and specific Echinococcus-genus antigen for human CE diagnosis is antigen B (AgB), an abundant lipoprotein of the hydatid cyst fluid (HF). The AgB protein moiety (apolipoprotein) is encoded by five genes (AgB1-AgB5), which generate mature 8 kDa proteins (AgB8/1-AgB8/5). These genes seem to be differentially expressed among Echinococcus species...

OBJECTIVE/BACKGROUND: Tuberculosis (TB) has been declared as a global emergency by the World Health Organization in 1993 and still remains one of the world's biggest threats. Worldwide, 9.6 million people have been estimated to have fallen ill with TB in 2014: 5.4 million men, 3.2 million women, and 1.0 million children. To reduce this burden, detection and treatment gaps must be addressed and new tools developed (Global TB report 2015). METHODS: Seroreactivity of the purified excretory secretory (ES) antigens ES-31, ES-43, ES-41, and ES-6 have been assessed in pulmonary TB (fresh, relapse, chronic, and latent), extrapulmonary TB, and in human immunodeficiency virus-TB coinfection...

Contrary to classical dogma, molecular epidemiological studies and mathematical modeling clearly show that the global drug-resistant tuberculosis (TB) epidemic is driven by transmission. Furthermore, there is mounting evidence demonstrating that amplification of resistance occurs during treatment, possibly as a result of insufficient active drugs being administered. To control the drug-resistant TB epidemic, it will be essential to implement new, rapid, and highly sensitive and specific diagnostic methods to decrease the diagnostic delay associated with culture-based testing...

Since 2002, there has been a gradual worldwide 1.3% annual decrease in the incidence of tuberculosis (TB). This is an encouraging statistic; however, it will not achieve the World Health Organization's goal of eliminating TB by 2050, and it is being compounded by the persistent global incidence of drug-resistant tuberculosis (DR-TB) acquired by transmission and by treatment pressure. One key to effectively control tuberculosis and the spread of multiresistant strains is accurate information pertaining to drug resistance and susceptibility...

OBJECTIVE/BACKGROUND: Tuberculosis (TB) is a major global threat to human health, especially in low-income countries. The diagnosis of TB is challenging because of the limitations of specificity and sensitivity with the current diagnostics. Novel, selective biomarkers for TB would be of great practical value. Exosomes are bioactive vesicles with 30-100nm in diameter, which are secreted from almost all cell types and are found in virtually every human body fluid. Exosomes transport micro-RNAs (miRNAs), which are post-transcriptional regulators of gene expression, around the body and allow miRNAs to modulate biological pathways in target cells...

Even in the 21st century, we are losing the battle against eradication of tuberculosis (TB). In 2015, 9.6 million people were estimated to have fallen ill with TB, of which 1.5 million people died. This is the real situation despite the well-structured treatment programs and availability of effective treatment options since the 1950s. The high mortality rate has been associated with other risk factors, such as the HIV epidemic, underlying diseases, and decline of socioeconomic standards. Furthermore, the problem of drug resistance that was recognized in the early days of the chemotherapeutic era raises serious concerns...

REVIEW
Balaji Srinivasan, Seoho Lee, David Erickson, Saurabh Mehta
Precision nutrition encompasses prevention and treatment strategies for optimizing health that consider individual variability in diet, lifestyle, environment and genes by accurately determining an individual's nutritional status. This is particularly important as malnutrition now affects a third of the global population, with most of those affected or their care providers having limited means of determining their nutritional status. Similarly, program implementers often have no way of determining the impact or success of their interventions, thus hindering their scale-up...
