Health risks assessment diagnosis of toxic chemicals (heavy metals) via food crops consumption irrigated with wastewater

The present study investigated the concentration of metals in commonly grown vegetables (Luffa acutangula L., Zea mays L., Solanum melongena L.) irrigated with waste water in District Bannu, Khyber Pakhtunkhwa, Pakistan. The pH (5.80) and electrical conductivity (13 dS/m) of waste water indicated the acidic nature that is not suitable for irrigation purposes. Soil and vegetables samples were analyzed for metals concentration through flame atomic absorption spectrometry (Varian FAAS-240). The findings showed that waste water irrigated soil was highly contaminated with Cd (4.62 mg/kg) which was above permissible limits set by European Union Standard (EU 2006, 2002). The concentrations of heavy metals such as Cr and Cd in vegetables were higher than the permissible limits set by World Health Organization/Food and Agriculture Organization U.S.A guidelines 2001. The health hazard quotient (HQ) of waste water irrigated vegetables was observed higher for Ni (0.699-0.1029 mg/kg), (0.0456-0.1040 mg/kg), (0.731-0.0994 mg/kg) in Luffa acutangula, Solanum melongena and Zea mays, respectively. The study concluded that the consumption of commonly grown vegetables in waste water zone of the study area may pose potential health threats in local population

Health promotion intervention to improve diet quality in children: a randomized trial

Published online: 2016 Apr 19. [Epub ahead of print]Objective This study aims to evaluate the impact of an intervention program, taught by trained teachers, on foods and nutrients components of the Diet Quality Index-International among children in Grades 1 to 4.Method A total of 464 children (239 female, 6-12 years) from seven elementary Portuguese schools participated in this randomized trial. Three schools were allocated to the intervention, and four to the control group. The intervention program was based on the health promotion model and social cognitive theory. Teachers previously trained by researchers in nutrition, healthy eating, and healthy cooking implemented the intervention in the classroom from November 2008 to March 2009. Sociodemographic, anthropometric, physical activity, and dietary assessments were performed before (2007/2008) and at the end of the intervention (2009). Dietary intake was gathered by a 24-hour dietary recall and the components of Diet Quality Index-International were defined.Results Children from the intervention schools reported a significantly higher adequacy in vegetable consumption (p = .018) and a significantly higher moderation in sodium consumption (p = .032) compared with the controllers.Conclusion Our study provides further support for the success of intervention programs that aim to enhance children's dietary intake. Implementing similar interventions can be promising to support vegetable consumption and moderate sodium intake.CIEC – Research Centre on Child Studies, IE, UMinho (FCT R&D unit 317), Portuga

Assessment of Trace Metals Concentration in Vegetables from Gombe Markets, Gombe State, Nigeria

This study determined the concentration of trace metals in vegetables (lettuce, tomato and cabbage) from Gombe markets, Gombe State, Nigeria. A total of 60 samples of vegetables were analyzed for trace metals (Cd, Pb, Mn, Cr, Zn, Ni and Cu) using Atomic Absorption Spectrophotometer (AAS). The mean concentration of Cd in lettuce, tomato and cabbage samples ranged from (0.05 - 0.06 mg/kg), (0.03 - 0.07 mg/kg) and (0.08 - 0.90 mg/kg),  Pb ranged from (BDL - 0.02 mg/kg), (BDL - 0.03 mg/kg) and (0.01 - 0.02 mg/kg), Mn ranged from (0.27 - 1.02 mg/kg), (0.09 - 0.12 mg/kg) and (0.25 - 0.31 mg/kg), Cr ranged from (0.05 - 0.65 mg/kg), (0.04 - 0.05 mg/kg) and (0.03 - 0.05 mg/kg), Zn ranged from (2.67 - 3.32 mg/kg), (1.93 - 2.87 mg/kg) and (2.45 - 3.26 mg/kg), Ni ranged from (0.68 - 0.77 mg/kg), (0.23 - 0.26 mg/kg) and (0.73 - 0.86 mg/kg), and Cu ranged from (0.95 - 0.97 mg/kg), (0.76 - 0.83 mg/kg) and (0.94 - 1.00 mg/kg) respectively.  The abundance of trace metals was found in decreasing order: Zn > Cu > Ni > Mn > Cr > Cd > Pb in lettuce, tomato and cabbage samples. The concentration of trace metals in the different vegetables were below the World Health Organization/Food and Agriculture Organization (WHO/ FAO) standard, except Cd in all studied samples. Therefore, monitoring and strict regulation is recommended to control the safety of vegetables sold in these markets

Effects of protein or amino-acid supplementation on the physical growth of young children in low-income countries.

Child growth stunting is common in low-income countries, possibly due to insufficient protein intakes. Most previous studies have concluded that children's protein intakes are adequate in relation to estimated requirements, but these studies did not consider issues of protein digestibility and effects of infection on dietary protein utilization. Using an alternative approach to assess the possible role of protein inadequacy in children's growth restriction, the results of 18 intervention trials in which supplementary protein or amino acids were provided to children ages 6-35 months and growth outcomes were reviewed. Eight studies conducted in hospitalized children recovering from acute malnutrition found that the recommended protein intake levels for healthy children supported normal growth rates, but higher intakes were needed for accelerated rates of "catch-up" growth. Ten community-based studies did not demonstrate a consistent benefit of supplemental protein on children's growth. However, weaknesses in the study designs limit the conclusions that can be drawn from these studies, and additional appropriately designed trials are needed to answer this question definitively. Recommendations for optimizing future study designs are provided herein

BIOTECHNOLOGY REGULATIONS AND THE WTO

This paper examines the regulation of trade in genetically modified organisms (GMOs) by the World Trade Organization (WTO). Despite rapid adoption of GMOs by a few exporters, many importers have developed relatively restrictive procedures for pre-market approval of GMOs, and are introducing mandatory labeling. While exporters have yet to seek a ruling from the WTO on these regulations, a trade dispute over GMOs is likely to occur before too long. Exporting countries will likely argue that importing countries' regulations are too restrictive, given existing scientific knowledge of the safety of current GM crops, and that labeling of GM foods is unnecessary due to the fact that they are typically similar to their conventional counterparts. In response, importing countries will likely argue that existing scientific knowledge about GMOs is insufficient, and that a precautionary approach to approval is appropriate. In addition, importers will claim that labeling is necessary due to the fact that they are not equivalent to their conventional counterparts, and consumers have a right to choose whether or not consume such foods, be it for religious, ethical or other reasons. In the event a panel will have decide on whether GM and non-GM products are "like goods", whether adequate risk assessment was undertaken for any regulation introduced for health reasons, whether labels constitute the "least trade distorting" way of meeting legitimate objectives, and whether regulations imply discrimination among suppliers or in favor of domestic producers. Experience with the SPS and TBT Agreements has not been extensive enough to indicate how such a panel might rule. But one can also view the issue in broader trade policy terms, as a balance between market access obligations that need to be adjusted as domestic regulations on new technologies are developed. A possible solution is for importing countries with tough GM regulation and mandatory labeling to offer reciprocal increases in market access for non-GM foods in compensation for any losses of market access for GM foods. There is a question though of whether such "rebalancing" is actually practical, and it would certainly add to the costs of dispute settlement in the WTO, but it may be the only viable solution in the long run if the WTO is not to be dragged in to evaluating social and ethical bases for regulation of biotechnology.Biotechnology, regulation, trade, WTO, International Relations/Trade, Research and Development/Tech Change/Emerging Technologies,

Accuracy of Loop-Mediated Isothermal Amplification for Diagnosis of Human Leptospirosis in Thailand

There is a lack of diagnostic tests for leptospirosis in technology-restricted settings. We developed loop-mediated isothermal amplification (LAMP) specific for the 16S ribosomal RNA gene (rrs) of pathogenic and intermediate group Leptospira species. The lower limit of detection was 10 genomic equivalents/reaction, and analytical specificity was high; we observed positive reactions for pathogenic/intermediate groups and negative reactions for non-pathogenic Leptospira species and other bacterial species. We evaluated this assay in Thailand by using a case–control study of 133 patients with laboratory-proven leptospirosis and 133 patients with other febrile illnesses. Using admission blood, we found that the rrs LAMP showed positive results in 58 of 133 cases (diagnostic sensitivity = 43.6, 95% confidence interval [CI] = 35.0–52.5) and in 22 of 133 controls (diagnostic specificity = 83.5, 95% CI = 76.0–89.3). Sensitivity was high for 39 patients who were culture positive for Leptospira spp. (84.6, 95% CI = 69.5–94.1). The rrs LAMP can provide an admission diagnosis in approximately half of patients with leptospirosis, but its clinical utility is reduced by a lower specificity

Contamination of heavy metals in Patin fish (Pangasius sp.) from Jelai River and Tembeling River, Pahang / Nur Amirah Amir

A study was conducted to determine and compare the concentration level of heavy metals in Pangasius sp. from Jelai River and Tembeling River, Pahang. Physical parameters measured were water temperature, dissolved oxygen concentration, pH and conductivity. Metals concentration in fish and grower fish feed samples were analyzed using Energy Dispersive X-Ray Fluorescence meanwhile the water samples was analyzed using Inductively Coupled Plasma- Optical Emission Spectroscopy. According to Malaysian National Interim Water Quality Standard (INWQS), Jelai River and Tembeling River were classified between moderate to good quality. Heavy metals in both rivers was found higher in aluminum followed by Fe and four elements (As, Fe, Mn and Zn) were found exceed the maximum allowable limit suggested by World Health Organization, Food and Agriculture Organization (WHO/FAO, 2004) and Malaysia Food and Drug Regulation (MFR, 1985). Generally, present of As, Cd and Ni within the Patin fish from both Jelai River and Tembeling River were due to the fish feed. The findings of this research study indicates that, Patin Fish in Jelai River contained high concentration of heavy metals compared to the samples in Tembeling River
