The emergence and wide-spread of drug-resistant bacteria including multi-drug resistant and pan-drug resistant pathogens which are associated with considerable mortality, represent a significant global health threat. 4-Quinolones which are exemplified by fluoroquinolones are the second largest chemotherapy agents used in clinical practice for the treatment of various bacterial infections. However, the resistance of bacteria to 4-quinolones develops rapidly and spreads widely throughout the world due to the long-term, inappropriate use and even abuse...

In North Sea and Port Açu (Brazil) coastal areas, high arsenic (As) concentrations were observed in water, soil and sediments. Therefore, the impact of this contamination on fish and shellfish species bought from local fishermen was studied. Total As was assessed with ICP-OES (Brazil) and ICP-MS (North Sea) after microwave digestion. Toxic As was assessed with liquid chromatography-ICP-MS (Brazil) and hydride generation-atomic fluorescence spectrometry (North Sea). All analytical methods comply with Quality Assurance/Quality Control procedures...

During the past several decades there has been an ever increasing emphasis for designers of new commercial (non-pharmaceutical) chemicals to include considerations of the potential impacts a planned chemical may have on human health and the environment as part of the design of the chemical, and to design chemicals such that they possess the desired use efficacy while minimizing threats to human health and the environment. Achievement of this goal would be facilitated by the availability of individuals specifically and formally trained to design such chemicals...

Childhood lead (Pb2+) intoxication is a public health problem of global proportion. Lead exposure during development produces multiple effects on the central nervous system including impaired synapse formation, altered synaptic plasticity, and learning deficits.In primary hippocampal neurons in culture and hippocampal slices, Pb2+ exposure inhibits vesicular release and reduces the number of fast-releasing sites, an effect associated with Pb2+ inhibition of NMDA receptor-mediated trans-synaptic Brain-Derived Neurotrophic Factor (BDNF) signaling...

The Fourth Global Symposium on Health Systems Research was themed around 'Resilient and responsive health systems for a changing world.' This commentary is the outcome of a panel discussion at the symposium in which the resilience discourse and its use in health systems development was critically interrogated. The 2014-15 Ebola outbreak in West-Africa added momentum for the wider adoption of resilient health systems as a crucial element to prepare for and effectively respond to crisis. The growing salience of resilience in development and health systems debates can be attributed in part to development actors and philanthropies such as the Rockefeller Foundation...

Being the principal causative agent of bacterial pneumonia, otitis media, meningitis and septicemia, the bacterium Streptococcus pneumoniae is a major global health problem. To highlight the molecular basis of this problem, we have portrayed essential biological processes of the pneumococcal life cycle in eight watercolor paintings. The paintings are done to a consistent nanometer scale based on currently available data from structural biology and proteomics. In this review article, the paintings are used to provide a visual review of protein synthesis, carbohydrate metabolism, cell wall synthesis, cell division, teichoic acid synthesis, virulence, transformation and pilus synthesis based on the available scientific literature within the field of pneumococcal biology...

Background: Recognition of the secondary preventive benefits of antiretroviral therapy (ART) has mobilized global efforts to 'seek, test, treat and retain' people living with HIV/AIDS (PLHIV) in HIV care. We aimed to determine the cost-effectiveness of a set of HIV testing and treatment engagement interventions initiated in British Columbia (BC), Canada in 2011-2013. Methods: Using a previously-validated dynamic, compartmental HIV transmission model, linked individual-level health administrative data for PLHIV and aggregate-level HIV testing data, we estimated the cost-effectiveness of primary care testing (hospital, emergency department, outpatient), ART initiation and ART retention initiatives, versus a counterfactual scenario approximating the status quo...

BACKGROUND: Positive affect (PA) and negative affect (NA) reflect subjective emotional experiences. Although related to depression and anxiety, these dimensions are distinct constructs representing affective states and patterns. Prior studies suggest that elevated depressive symptoms are associated with risk of mild cognitive impairment (MCI) and probable dementia, but whether affective states are associated with cognitive impairment is still unknown. The present study examined relationships between baseline affective states and cognitive impairment (MCI, probable dementia) in non-depressed women...

BACKGROUND AND OBJECTIVE: Cardiovascular disease and type 2 diabetes pose a global health burden. Therefore, clarifying the pathology of these risk factors is essential. Previous studies have found positive and negative associations between one or more cardiovascular risk factors and brain-derived neurotrophic factor (BDNF) probably due to diverse methodological approaches when analysing peripheral BDNF levels. Moreover, only a few studies have been performed in youth populations. Consequently, the main objective of this study was to examine the association between serum BDNF and a composite z-score consisting of six cardiovascular risk factors...

The emergence of the Middle East Respiratory Syndrome Coronavirus (MERS-CoV) infections has become a global issue of dire concerns. MERS-CoV infections have been identified in many countries all over the world whereas high level occurrences have been documented in the Middle East and Korea. MERS-CoV is mainly spreading across the geographical region of the Middle East, especially in the Arabian Peninsula, while some imported sporadic cases were reported from the Europe, North America, Africa, and lately Asia...

BACKGROUND: Limited studies have explored the relationship between air pollution and rheumatoid arthritis (RA), with the results being somewhat inconsistent. METHODS: This was a retrospective cohort study that included 322,301 subjects aged 30-50 years, selected from the National Health Insurance Research Database in Taiwan, were followed from 2001 to 2010. We used a time-dependent extended Cox model and incorporated time-dependent variables to estimate the associations between the annual mean concentrations of air pollutants with RA, including carbon monoxide (CO), nitrogen dioxide (NO2), ozone (O3), particles with an aerodynamic diameter less than 10 μm (PM10), and sulfur dioxide (SO2), and reported the hazard ratio (HR) and 95% confidence interval (CI)...

BACKGROUND: The environmental health of children is one of the great global health concerns. Exposures in utero and throughout development can have major consequences on later health. However, environmental risks or disease burdens vary from region to region. Birth cohort studies are ideal for investigating different environmental risks. METHODS: The principal investigators of three birth cohorts in Asia including the Taiwan Birth Panel Study (TBPS), the Mothers and Children's Environmental Health Study (MOCEH), and the Hokkaido Study on Environment and Children' Health (Hokkaido Study) coestablished the Birth Cohort Consortium of Asia (BiCCA) in 2011...

Public Health (PH) in Europe has become much more vocal about its moral understandings since 1992. The rising awareness that PH issues were inseparable from issues of human rights and social justice almost self-evidently directed the agenda of EUPHA and the European Public Health (EPH)-conferences. Problems of cultural and behavioural change, and environmental issues on a global scale were also added. The Section Ethics in PH invited the EPH community to join in 'arm chair thinking': coming together at conferences not only to share the 'how' and 'what' of PH research, practices and policies but also the 'why'...

Delay in treating active tuberculosis (TB) impedes disease control by allowing ongoing transmission, and may explain the unexpectedly modest declines in global TB incidence. Even though China has achieved TB control targets under the global Directly Observed Treatment, Short course (DOTS) strategy, TB prevalence in western provinces, including Yunnan, is not decreasing. This cross-sectional study investigates whether prolonged delay in identifying and correctly treating TB patients, which is not routinely monitored, persists even when there is a well-functioning TB control programme and global targets are being met...

With funding for tuberculosis (TB) research decreasing, and the high global disease burden persisting, there are calls for increased investment in TB research. However, justification of such investments is questionable, when translation of research outputs into policy and health care improvements remains a challenge for TB and other diseases. Using TB in Cambodia as a case study, we investigate how evidence needs of national policy makers are addressed by topics covered in research publications. We first conducted a systematic review to compile all studies on TB in Cambodia published since 2000...

The sudden emergence of infectious pathogens such as Zika virus (ZIKV) holds global health concerns. Recent dissemination of ZIKV from Pacific to Americas with an upsurge of congenital anomalies and Guillain Barre Syndrome (GBS) in adults has created an alarming situation. High-throughput studies are in progress to understand ZIKV's mode of pathogenesis and mechanism of immune escape, yet the pathogenesis remains obscure. Mainly ZIKV's envelope (E) protein and nonstructural proteins (mainly NS1 and NS5) manipulate host cell to support viral immune escape by modulation of the interferon pathway and complement antagonism...

Decline-diseases are complex and becoming increasingly problematic to tree health globally. Acute Oak Decline (AOD) is characterized by necrotic stem lesions and galleries of the bark-boring beetle, Agrilus biguttatus, and represents a serious threat to oak. Although multiple novel bacterial species and Agrilus galleries are associated with AOD lesions, the causative agent(s) are unknown. The AOD pathosystem therefore provides an ideal model for a systems-based research approach to address our hypothesis that AOD lesions are caused by a polymicrobial complex...
