Neural tube defects (NTDs) occur secondary to failed closure of the neural tube between the third and fourth weeks of gestation. The worldwide incidence ranges from 0.3 to 200 per 10,000 births with the United States of American NTD incidence at around 3-6.3 per 10,000 dependent on race and socioeconomic background. Human NTD incidence has fallen by 35-50% in North America due to mandatory folic acid fortification of enriched cereal grain products since 1998. The US Food and Drug Administration has approved the folic acid fortification of corn masa flour with the goal to further reduce the incidence of NTDs, especially among individuals who are Hispanic...

BACKGROUND: Tobacco smoking and smoke exposure during pregnancy and childhood cause considerable childhood morbidity and mortality. We did a systematic review and meta-analysis to investigate whether implementation of WHO's recommended tobacco control policies (MPOWER) was of benefit to perinatal and child health. METHODS: We searched 19 electronic databases, hand-searched references and citations, and consulted experts to identify studies assessing the association between implementation of MPOWER policies and child health...

European honey bees Apis mellifera are important commercial pollinators that have suffered greater than normal overwintering losses since 2007 in North America and Europe. Contributing factors likely include a combination of parasites, pesticides, and poor nutrition. We examined diet diversity, diet nutritional quality, and pesticides in honey bee-collected pollen from commercial colonies in the Canadian Maritime Provinces in spring and summer 2011. We sampled pollen collected by honey bees at colonies in four site types: apple orchards, blueberry fields, cranberry bogs, and fallow fields...

Mitigation of emerging infectious diseases that threaten global biodiversity requires an understanding of critical host and pathogen responses to infection. For multihost pathogens where pathogen virulence or host susceptibility is variable, host-pathogen interactions in tolerant species may identify potential avenues for adaptive evolution in recently exposed, susceptible hosts. For example, the fungus Pseudogymnoascus destructans causes white-nose syndrome (WNS) in hibernating bats and is responsible for catastrophic declines in some species in North America, where it was recently introduced...

James L Davis, Nadya T Vinogradova
The tide-gauge record from the North American East Coast reveals significant accelerations in sea level starting in the late twentieth century. The estimated post-1990 accelerations range from near zero to ∼0.3 mm yr(-2). We find that the observed sea level acceleration is well modeled using several processes: mass change in Greenland and Antarctica as measured by the Gravity Recovery and Climate Experiment satellites; ocean dynamic and steric variability provided by the GECCO2 ocean synthesis; and the inverted barometer effect...

Alma Vega, Emma Aguila
Older adults make up an increasing share of new legal immigrants to the United States. These immigrants are often financially dependent on family since they are often barred from receiving several U.S. support programmes and are less likely to receive U.S. retirement benefits than natives. However, little information exists as to whether they receive retirement income from abroad. Using the New Immigrant Survey (N=2,150), we find that only 8.1 per cent of older recent immigrants report receiving foreign retirement income...

OBJECTIVE: To examine the effectiveness of the three primary treatments for ureteropelvic junction obstruction (i.e., open pyeloplasty, minimally invasive pyeloplasty, and endopyelotomy) as assessed by failure rates. MATERIALS AND METHODS: Using MarketScan(®) data, we identified adults (ages 18-64) who underwent treatment for ureteropelvic junction obstruction between 2002 and 2010. Our primary outcome was failure (i.e., need for a secondary procedure). We fit a Cox proportional hazards model to examine the effects of different patient, regional, and provider characteristics on treatment failure...

The medial preoptic area (mPOA) participates in the temperature and cardiovascular control. The mPOA receives inputs from limbic structures and sends projections to hypothalamus and brainstem. Moreover, stress elicits pronounced neuronal activation in mPOA, suggesting its involvement in central neural pathway mediating stress responses. In the present study, we report the effect of acute mPOA neurotransmission inhibition using cobalt chloride (CoCl2-nonselective synapse blocker) on the mean arterial pressure (MAP), heart rate (HR), body and tail temperature (Tbody and Ttail, respectively), as well as on the HR component of baroreflex...

OBJECTIVES: Recently, a new Nutritional Competence Score (NCS) has been shown to associate with hospitalization and outcome in hemodialysis patients. The aim of this study was to investigate the dynamics, the individual components, and the impact of hospitalizations of this score's trajectory in the year before death. In addition, we investigated whether dynamics in the NCS add additional independent prognostic value over a single cross-sectional assessment. DESIGN: We included all Fresenius Medical Care North America patients who initiated hemodialysis between January 1, 2006, and December 31, 2011 with data on all 5 NCS components (serum albumin, creatinine, phosphate, equilibrated normalized protein catabolic rate, and interdialytic weight gain) in at least 1 month...

Senecavirus A (SVA) infection was recently confirmed in pigs in Brazil, United States of America and Canada. To better understand the molecular characteristics of isolated SVA genomes, we first reported genome-wide comprehensive analyses of codon usage and various factors that have contribute to the molecular evolution in SVA. The effective number of codons (ENC) ranged from 54.51 to 55.54 with an average of 54.87 ± 0.285, which reveals a relatively stable nucleotide composition. We found that codon usage bias of the SVA was low...

There is a significant amount of interest among general surgery residency training programs in North America to have a rotation in an underserved part of the world. Usually, these global surgery rotations for the general surgery residents have been extended in duration to allow for emersion and continuity. There is similar interest among a few of the pediatric surgery training programs to initiate short, one month rotations in the global surgery arena as part of the two year pediatric surgery residency training...

Trypanosoma cruzi, the etiological agent of the Chagas' disease in Latin America undergoes a complex life cycle involving two hosts, a mammalian host and a reduviid insect vector (triatomine). In the insect midgut the parasite multiplies as epimastigote forms, which rely on endocytosis for their energy requirement. We recently showed that posttranslational modification of endocytic N-glycoproteins by tomato lectin (TL) binding-N-glycans is crucial for receptor-mediated endocytosis (RME) in epimastigote forms...

During screening of non-cultivated (wild) grapevine (Vitis sp.) from Napa County, California for the grapevine red blotch virus (GRBV; genus Glabrovirus, family Geminiviridae), an atypical polymerase chain reaction product pattern was observed. Rolling circle amplification followed by cloning and sequencing revealed the presence of a circular DNA characteristic of geminiviruses. The complete genome of nine isolates of the virus ranged from 3204 to 3278 nt in size. The genome most closely resembled that of GRBV in both sequence (57 to 59% identity) and organization...

Forensic humanitarian action is aimed at alleviating suffering and maintaining human dignity, with the victims and their families at the core. International recommendations emphasize the importance of psychological support and psychosocial work as an integral part of forensic investigations into missing persons. Psychosocial action does not simply refer to emotional support but is based on the idea of the individual being the holder of rights, encouraging decision taking, affirming actions, and elaborating personal and collective histories...

Chikungunya (CHIK) is a mosquito-borne virus (CHIKV) infection that recently appeared in the Americas and thousands of confirmed cases have been reported in Brazil since the first autochthonous cases were reported in September 2014. We reported four cases of CHIK in kidney transplant recipients. The diagnosis was confirmed by positive CHIKV real-time polymerase chain reaction in two cases and positive CHIKV-IgM serology in two patients. The time between transplantation and CHIKV infection ranged from 2 to 11 years...

BACKGROUND: Chagas disease (CD) is an endemic zoonosis that occurs in Latin-America and is caused by the parasite Trypanosoma cruzi. Early detection of T. cruzi in liver transplant recipients at risk may avoid complications from CD. The aim of this study was to examine the pre-operative evaluation and follow-up of CD after liver transplantation (LT) of patients at risk of CD using real-time quantitative polymerase chain reaction (qPCR) for T. cruzi. METHODS: Between January 2009 and June 2016, 13 (12...

African swine fever (ASF) causes greater sanitary, social and economic impacts on swine herds than many other swine diseases. Although ASF was first described in 1921 and it has affected more than fifty countries in Africa, Europe and South America, several key issues about its pathogenesis, immune evasion and epidemiology remain uncertain. This article reviews the main characteristics of the causative virus, its molecular epidemiology, natural hosts, clinical features, epidemiology and control worldwide. It also identifies and prioritizes gaps in ASF from a horizontal point of view encompassing fields including molecular biology, epidemiology, prevention, diagnosis and vaccine development...
