Results from the Philippines' 2022 report card on physical activity for children and adolescents.

Background/Objective: The 2022 Philippine Report Card on Physical Activity for Children and Adolescents provides a comprehensive assessment of physical activity and other related behaviors, including the various factors and settings that influence these behaviors. It serves as an advocacy tool to increase awareness of the physical activity situation among children and young people in the country. This article describes the development and results of the first Philippine Report Card on Physical Activity for Children and Adolescents. Methods: Following a systematic process provided by the Active Healthy Kids Global Alliance, a team consisting of 25 sports and physical activity specialists identified and reviewed the best available nationally representative data related to physical activity indicators. These data were then used to inform the grades of the ten (10) physical activity indicators. Results: Sufficient data were identified to assign grades to five (5) indicators: Overall Physical Activity (F), Active Transportation (D), Sedentary Behavior (B), School (C-), and Government (B). Insufficient data existed to assign grades to the remaining five (5) indicators: Organized Sport and Physical Activity, Active Play, Physical Fitness, Family and Peers, and Community and Environment. Conclusion: Despite government policies related to physical activity in the country, the majority of children and adolescents in the Philippines do not meet the recommended amount of physical activity for health. More work is needed to improve the translation of these policies into measurable programs, highlighting the need to create better physical activity opportunities and develop national surveillance mechanisms.

New cancer cases attributable to diet among adults aged 30-84 years in France in 2015.

This study aimed to estimate the number of new cancer cases attributable to diet among adults aged 30-84 years in France in 2015, where convincing or probable evidence of a causal association exists, and, in a secondary analysis, where at least limited but suggestive evidence of a causal association exists. Cancer cases attributable to diet were estimated assuming a 10-year latency period. Dietary intake data were obtained from the 2006 French National Nutrition and Health Survey. Counterfactual scenarios of dietary intake were based on dietary guidelines. Corresponding risk relation estimates were obtained from meta-analyses, cohort studies and one case-control study. Cancer incidence data were obtained from the French Network of Cancer Registries. Nationally, unfavourable dietary habits led to 16 930 new cancer cases, representing 5·4 % of all new cancer cases. Low intake of fruit and dietary fibre was the largest contributor to this burden, being responsible for 4787 and 4389 new cancer cases, respectively. If this is expanded to dietary component and cancer pairs with at least limited but suggestive evidence of a causal association, 36 049 new cancer cases, representing 11·6 % of all new cancer cases, were estimated to be attributable to diet. These findings suggest that unfavourable dietary habits lead to a substantial number of new cancer cases in France; however, there is a large degree of uncertainty as to the number of cancers attributable to diet, including through indirect mechanisms such as obesity, and therefore additional research is needed to determine how diet affects cancer risk.

Effect of the mycotoxins enniatin B and deoxynivalenol on the wheat aphid Sitobion avenae and on the predatory lacewing Chrysoperla carnea.

BACKGROUND: Fusarium species are responsible for Fusarium head blight (FHB) in wheat, resulting in yield losses and mycotoxin contamination. Deoxynivalenol (DON) and enniatins (ENNs) are common mycotoxins produced by Fusarium, affecting plant, animal and human health. Although DON's effects have been widely studied, limited research has explored the impact of ENNs on insects. This study examines the influence of DON and enniatin B (ENB), both singularly and in combination, on the wheat aphid Sitobion avenae and one of its predators, the lacewing Chrysoperla carnea. RESULTS: When exposed to DON (100 mg L-1) or DON + ENB (100 mg L-1), S. avenae exhibited significantly increased mortality compared to the negative control. ENB (100 mg L-1) had no significant effect on aphid mortality. DON-treated aphids showed increasing mortality from 48 to 96 h. A dose-response relationship with DON revealed significant cumulative mortality starting at 25 mg L-1. By contrast, C. carnea larvae exposed to mycotoxins via cuticular application did not show significant differences in mortality when mycotoxins were dissolved in water but exhibited increased mortality with acetone-solubilized DON + ENB (100 mg L-1). Feeding C. carnea with aphids exposed to mycotoxins (indirect exposure) did not impact their survival or predatory activity. Additionally, the impact of mycotoxins on C. carnea was observed only with acetone-solubilized DON + ENB. CONCLUSIONS: These findings shed light on the complex interactions involving mycotoxins, aphids and their predators, offering valuable insights for integrated pest management strategies. Further research should explore broader ecological consequences of mycotoxin contamination in agroecosystems. © 2024 Society of Chemical Industry.

Natural Occurrence of Beauvericin and Enniatins in Corn- and Wheat-Based Samples Harvested in 2017 Collected from Shandong Province, China.

Totals of 158 corn and corn-based samples and 291 wheat and wheat-based samples from Shandong province, China in 2017 were analyzed for five mycotoxins including beauvericin (BEA), enniatin A (ENA), enniatin A1 (ENA1), enniatin B (ENB), and enniatin B1 (ENB1) by high-performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS). BEA was the predominant toxin detected, followed by ENB, ENA1, ENA, and ENB1. Corn and corn-based samples were more easily contaminated by BEA with an average concentration of 65.26 µg/kg, compared with that in wheat and wheat-based samples (average = 0.41 µg/kg). Concentrations of BEA, ENA, and ENB1 in corn kernels, flours, and flakes were significantly different (Kruskal⁻Wallis Test, p < 0.05), as well as for BEA, ENA, ENB, and ENB1 in wheat kernels, flours, and noodles (Kruskal⁻Wallis test, p < 0.05). Furthermore, 59.5% (94/158) and 59.8% (174/291) corn- and wheat-based samples were co-contaminated by at least two mycotoxins, respectively. Positive correlations in concentrations were observed in corn between levels of ENA and ENB1, ENA and ENB, ENA1 and ENB1, as well as in wheat between BEA and ENA, BEA and ENA1, BEA and ENB, BEA and ENB1, ENA and ENA1, ENA and ENB, ENA and ENB1, ENA1 and ENB, ENA1 and ENB1, and ENB and ENB1. These results demonstrate that co-contamination of BEA and enniatins (ENNs) in corn- and wheat-based samples from Shandong, China is very common. More data on the contamination of five mycotoxins in cereal and cereal-based samples nationwide are needed.

A systematic approach for designing a HBM pilot study for Europe.

The objective of COPHES (Consortium to Perform Human biomonitoring on a European Scale) was to develop a harmonised approach to conduct human biomonitoring on a European scale. COPHES developed a systematic approach for designing and conducting a pilot study for an EU-wide cross-sectional human biomonitoring (HBM) study and for the implementation of the fieldwork procedures. The approach gave the basis for discussion of the main aspects of study design and conduct, and provided a decision making tool which can be applied to many other studies. Each decision that had to be taken was listed in a table of options with their advantages and disadvantages. Based on this the rationale of the decisions could be explained and be transparent. This was important because an EU-wide HBM study demands openness of all decisions taken to encourage as many countries as possible to participate and accept the initiative undertaken. Based on this approach the following study design was suggested: a cross-sectional study including 120 children aged 6-11 years and their mothers aged up to 45 years from each participating country. For the pilot study the children should be sampled in equal shares in an urban and a rural location. Only healthy children and mothers (no metabolic disturbances) should be included, who have a sufficient knowledge of the local language and have been living at least for 5 years at the sampling location. Occupational exposure should not be an exclusion criterion. Recruitment should be performed via inhabitant registries or schools as an alternative option. Measures suitable to increase the response rate should be applied. Preferably, the families should be visited at home and interviewed face-to-face. Various quality control measures to guarantee a good fieldwork performance were recommended. This comprehensive overview aims to provide scientists, EU officials, partners and stakeholders involved in the EU implementation process full transparency of the work carried out in COPHES. Thus this report presents the discussion and consensus in COPHES on the main aspects of designing and conducting fieldwork of a human biomonitoring study. Furthermore, it provides an example for a systematic approach that may be useful to other research groups or pan-European research initiatives. In the study protocol that will be published elsewhere these aspects are elaborated and additional aspects are covered (Casteleyn et al., 2012). Meanwhile the respective pilot study DEMOCOPHES had been conducted and assessed. The results and lessons learned will be published elsewhere.

Mycotoxins: occurrence, toxicology, and exposure assessment.

Mycotoxins are abiotic hazards produced by certain fungi that can grow on a variety of crops. Consequently, their prevalence in plant raw materials may be relatively high. The concentration of mycotoxins in finished products is usually lower than in raw materials. In this review, occurrence and toxicology of the main mycotoxins are summarised. Furthermore, methodological approaches for exposure assessment are described. Existing exposure assessments, both through contamination and consumption data and biomarkers of exposure, for the main mycotoxins are also discussed.
