    November: Health Consequences of Exposure to E-Waste: a systematic review.
    Air Pollution
    As the literature on traffic-related air pollution and childhood cancers is inconclusive the authors sought to examine associations between childhood cancers and traffic-related pollution exposure. With unconditional logistic regression, a per interquartile range increase in exposure to traffic-related pollution during the first trimester was associated with acute lymphoblastic leukemia (ALL); germ cell tumors, particularly teratomas; and retinoblastoma, particularly bilateral retinoblastoma. Retinoblastoma was also associated with average PM2.5 concentrations during pregnancy, and ALL and teratomas were associated with traffic density near the child’s residence at birth. The authors  estimated weak associations between early exposure to traffic pollution and several childhood cancers. They concluded that because this is the first study to report on traffic pollution in relation to retinoblastoma or germ cell tumors, and both cancers are rare, the findings require replication in other studies.
    Environmental  Health Perspectives
    The metabolic disruptor hypothesis postulates that environmental pollutants may be risk factors for metabolic diseases. Because insulin resistance is involved in most metabolic diseases and current health care prevention programs predominantly target insulin resistance or risk factors thereof, a critical analysis of the role of pollutants in insulin resistance might be important for future management of metabolic diseases. The authors aimed to critically review the available information linking pollutant exposure to insulin resistance and to open the discussion on future perspectives for metabolic disruptor identification and prioritization strategies.
    Environmental  Health Perspectives
    The population exposed to potentially hazardous substances through inappropriate and unsafe management practices related to disposal and recycling of end-of-life electrical and electronic equipment, collectively known as e-waste, is increasing. The authors aimed to summarise the evidence for the association between such exposures and adverse health outcomes. They recorded plausible outcomes associated with exposure to e-waste including change in thyroid function, changes in cellular expression and function, adverse neonatal outcomes, changes in temperament and behaviour, and decreased lung function. Findings from most studies showed increases in spontaneous abortions, stillbirths, and premature births, and reduced birthweights and birth lengths associated with exposure to e-waste.
    The Lancet Global Health
    Water and Sanitation
    Drinking water supplies at Marine Corps Base Camp Lejeune were contaminated with trichloroethylene, tetrachloroethylene, benzene, vinyl chloride and trans-1,2-dichloroethylene during 1968 through 1985. The authors conducted a case control study to determine if children born during 1968 and 1985 to mothers with residential exposure to contaminated drinking water at Camp Lejeune during pregnancy were more likely to have childhood hematopoietic cancers, neural tube defects (NTDs), or oral clefts. For cancers, exposures during the first year of life were also evaluated. They concluded that although confidence intervals were wide, odds ratios (ORs) suggested associations between drinking water contaminants and NTDs. ORs suggested weaker associations with childhood hematopoietic cancers.
    Environmental  Health
    During previous research into drinking water quality in Peru, it was found that water was becoming contaminated in households, and there was a lack of understanding surrounding this contamination. It was felt that returning these findings to the community could build capacity, enabling people to make more informed choices about drinking water practices. Several participatory methods were explored. Thirty-five participants explored their understanding of drinking water and factors that caused contamination. In the process the researcher also gained a better understanding of local knowledge and perceptions. They concluded that this type of knowledge exchange has important implications for future implementation of new water technologies and engineering projects.

    The aryl hydrocarbon receptor (AHR) is a ligand-activated transcription factor that regulates the expression of xenobiotic detoxification genes and is a critical mediator of gene–environment interactions. Many AHR target genes identified by genome-wide gene expression profiling have morphogenetic functions, suggesting that AHR may play a role in embryonic development. The objective of this study was to characterize the developmental functions of the AHR. The authors studied the consequences of AHR activation by the agonist 2,3,7,8-tetrachlorodibenzo-p-doxin, and the result of its repression by the antagonists 6,2,4-trimethoxyflavone and CH 223191 or by short-hairpin RNA-mediated Ahr knockdown during spontaneous differentiation of embryonic stem  cells into cardiomyocytes. Disruption of AHR expression levels resulted in gene expression changes that perturbed cardiomyocyte differentiation. The authors concluded that the main function of the AHR during development appeared to be the coordination of a complex regulatory network responsible for attainment and maintenance of cardiovascular homeostasis.

    Improved urban transport strategies can bring a myriad of benefits to India, from reductions in CO2 emissions to a more mobile and inclusive society, according to a new report. UNEP (18/12/13)
    The decline in education for Syrian children has been the sharpest and most rapid in the history of the region. “Education Interrupted” highlights that since 2011 nearly 3 million children from Syria have been forced to quit their education as fighting has destroyed classrooms, left children too terrified to go to school, or seen families flee the country. Progress achieved over decades has been reversed in under three years. UNICEF (13/12/13)
    On UNICEF’s 67th birthday, the organization released a new report showing that the births of nearly 230 million children under-five have never been registered; approximately one in three of all children under-five around the world. UNICEF (11/12/13)
    The Atlas examines the environmental change that has taken place at more than 80 locations across the Arab region, using a combination of on-the-ground photographs, current and historical satellite images, with a narrative based on extensive scientific evidence. UNEP (10/12/13)
    MiNDbank, a new WHO database goes online, presenting a wealth of information about mental health, substance abuse, disability, human rights and the different policies, strategies, laws and service standards being implemented in different countries. It also contains key international documents and information. WHO (10/12/13)
    One month after Typhoon Haiyan hit the Philippines, WHO identifies as top priorities expanding essential health services, reviving clinics and hospitals, preventing disease and scaling up mental health services as the relief effort shifts from emergency to early recovery programmes.
