Critical Reviews in Toxicology | Year: 2011
The European Centre for Ecotoxicology and Toxicology of Chemicals (ECETOC), the International Life Sciences Institute (ILSI) Research Foundation (RF), and the ILSI Health and Environmental Sciences Institute (HESI) hosted a workshop in November 2009 to review current practice in the application of mode of action (MOA) considerations in chemical risk assessment. The aim was to provide a rationale for a more general, but flexible approach and to propose steps to facilitate broader uptake and use of the MOA concept. There was consensus amongst the workshop participants that it will require substantial effort and cooperation from the multiple disciplines involved to embrace a common, consistent, and transparent approach. Setting up a repository of accepted MOAs and associated guidance concerning appropriate data to support specific MOAs for critical effects would facilitate categorization of chemicals and allow predictions of toxicity outcomes by read-across. This should in future contribute to the reduction of toxicity testing in animals. The workshop participants also acknowledged the value and importance of human data and the importance of integrating information from biological pathway analyses into current MOA/human relevance frameworks. © 2011 Informa Healthcare USA, Inc.

A 15-year-old boy had persistent and refractory erythroderma since early childhood. His parents noticed polycyclic skin lesions and hair fragility around the age of 5 years. He was treated by a local untrained practitioner for more than 3 years without any significant improvement, and he developed weight gain, thinning of skin, muscle weakness and growth retardation. He was evaluated in 2015 and found to have iatrogenic Cushing's disease with severe skeletal complications and pituitary-Adrenal-gonadal suppression, which persisted despite gradual withdrawal of steroids. © 2017 BMJ Publishing Group Ltd.

Background: MINI SALTEN is a program developed to increase moderate to vigorous physical activity (PA) and improve eating habits at home and school in first grade children. It aims to assess the effects of a technology family-based and PA school-based intervention. The purpose of this manuscript is to describe the protocol design and the MINISALTEN intervention. Methods: This is cluster-randomized controlled trial designed to run from July 2015 to November 2016 in 12 public schools of the city of Buenos Aires, matched for socio-demographic characteristics. The intervention is based on two main components: (a) “active breaks” (AB): implemented during school breaks by a PA instructor; (b) “virtual” (V): web-based contents delivered to the families via a multiplatform application. Using a computer generated random sequence participants are allocated to one of four intervention conditions: (AB), (V), (AB + V), and control (C). Outcomes are measured at baseline and 12 months post intervention, and will include data collected from the child and her/his mother/father or guardian. Primary outcome measures are: PA and sedentary behaviour (measured with accelerometers). Secondary outcome measures related are: percentage of kilocalories (kcal) from added sugars, and from total and saturated fats; grams of fruits and vegetables; and number of snacks and kcal coming from their added sugars and total and saturated fats. Family socio-economic level, home environment, and school environment will also be assessed. Statistical analysis is on an intention-to-treat principle. Baseline characteristics are described using summary measures and mixed models (with school as random effect). The effect of the two interventions will be estimated using a generalized mixed linear model with link and distribution selected according to the type of outcome. Included random effects are: child (or mother/father or guardian) accounting for repeated measures; school accounting for cluster induced by school. The most parsimonious model for each outcome will be reported. The False Discovery Rate criterion will be used to correct for multiple testing in non-planned analyses. Discussion: It is a pioneer assessment of the impact of a technology-based virtual intervention and a school-based PA program, designed to prevent obesity, and involving the parents at public schools of Buenos Aires.

In May 2003, the International Life Sciences Institute (ILSI) released Version 1.0 of the Crop Composition Database (http://www.cropcomposition.org), a comprehensive public database that provides information on the natural variability in composition of conventionally bred crops. Currently, the database contains more than 115,000 data points representing 132 compositional components in corn, soybean and cotton. In 2009 the database logged more than 30,000 site visits from 122 countries around the world. ILSI has made a number of improvements to the original database and recently developed Version 4.0, which will be released for public access in 2010. Version 4.0 presents an intuitive graphical-user interface (GUI), significantly increased performance, added security, and additional features such as unit conversion and multiple output options. Another notable improvement in Version 4.0 is the Summary of Search Results tool, which allows users to immediately view data of interest and guides the preparation of output reports. This paper summarizes some of the enhanced features and usage of the database, which continues to be a valuable tool for characterizing the composition of conventional crops. © 2010 International Life Sciences Institute.

Vitamin D deficiency is a major public health problem, needing immediate attention. We studied the effect of vitamin D fortification of milk in school children. Our results show that fortification of milk is safe and effective strategy to deal with widespread vitamin D deficiency. Introduction: Vitamin D deficiency among school children and adolescents is a well-documented major public health problem, needing immediate attention. To assess the effect of vitamin D fortified milk on serum 25 hydroxy vitamin D [S.25(OH)D] levels, we carried out a prospective double-blind randomized control trial in apparently healthy school children, aged 10-14 years. Methods: Of 776 subjects recruited out of 796 who consented, 713 (boys-300; girls-413) completed the study. Subjects were randomized into three groups. Group A (n = 237) received 200 ml of unfortified milk per day while group B (n = 243) and group C (n = 233) received 200 ml of milk fortified with 600 IU (15 μg) and 1,000 IU (25 μg) of vitamin D per day for 12 weeks. Serum calcium, phosphate, alkaline phosphatase, S.25(OH)D, and urinary calcium/creatinine ratio were estimated at baseline and after supplementation. Results: Hypovitaminosis D [25(OH)D < 20 ng/ml] was observed in 92.3 % subjects with mean S.25(OH)D level of 11.69 ± 5.36 ng/ml. There was no significant difference in S.25(OH)D levels among the three groups at baseline. The mean percentage change in S.25(OH)D level in groups B (137.97 %) and C (177.29 %.) were significantly greater than group A (-5.25 %). The percentage of subjects having S.25(OH)D levels >20 ng/ml following supplementation were 5.9 % in group A, 69.95 % in group B, and 81.11 % in group C in comparison to 6.32 %, 4.9 % and 12 %, respectively, at baseline. Conclusion: Fortification of milk with vitamin D is an effective and safe strategy in improving S.25(OH)D levels in children aged 10-14 years. © 2013 International Osteoporosis Foundation and National Osteoporosis Foundation.

Introduction Pompe disease (PD) is a rare autosomal recessive metabolic disorder which is caused by the absence or deficiency of the acid alpha-glucosidase lysosomal enzyme in the tissues of affected individuals. Objective The objective of this consensus is to review the current guidelines and provide recommendations for a correct diagnosis, evaluation, management, and treatment of patients with PD. Methods We organized a consensus with a foreign guest and national professionals experienced in PD in the areas of clinic, pediatric clinic, laboratory diagnosis, neuropathology, neumonology, nutrition, neurology, metabolic diseases, neuromuscular diseases (NMD) and rehabilitation of patients with MND. We conducted a literature review of the existing publications and articles relevant to EP up to date, individually and in small group meetings organized by field of work and specialty. The final terms of the document were agreed upon by the entire working group. Each participant provided their declaration of conflict of interests. Conclusions The Argentine Consensus for Pompe disease was developed, considering aspects of the pathophysiology, clinical manifestations, diagnosis and treatment of this disease. Being a rare condition for which the available data are limited, these recommendations should be considered as expert opinion.© 2014 Sociedad Neurologica Argentina. Publicadopor Elsevier Espana.

More than 2 billion individuals globally suffer some degree of deficiency of one or more micronutrients, with the largest numbers in Africa and Asia. Fortification of foods with vitamins and minerals is a proven public health intervention. In Asia, salt iodization, fortified flour and condiments such as fish sauce and soy sauce are reaching hundreds of millions. However, many individuals still do not have adequate intakes of numerous micronutrients, and better fortification strategies and practices will help to alleviate these deficiencies. The International Life Sciences Institute (ILSI) has supported research and scientific dialog about technical and health issues related to micronutrients. Recent studies have indicated widespread vitamin D deficiency among children in SE Asia, and in India. A new trial shows the efficacy of vitamin D-fortified milk in addressing deficiencies, which may have applicability in school feeding programs in India and other parts of Asia. Infant nutrition is also critical, and complementary foods can play an important role after exclusive breastfeeding in providing critical nutrients. A formulation developed in China, Ying Yang Bao, has shown significant reduction of anemia and improved growth in infants. Fortification in Asia has the potential to greatly reduce micronutrient deficiencies and improve health, but more structured efforts are needed to achieve these goals. © 2015, Center for Academic Publications Japan.

An online survey was conducted by the International Life Sciences Institute, Food Biotechnology Committee, on the use of qualitative and quantitative polymerase chain reaction (PCR) assays for cauliflower mosaic virus 35S promoter and Agrobacterium tumefaciens Tnos DNA sequence elements for the detection of genetically engineered (GE) crop plant material. Forty-four testing laboratories around the world completed the survey. The results showed the widespread use of such methods, the multiplicity of published and in-house methods, and the variety of reference materials and calibrants in use. There was an interest on the part of respondents in validated quantitative assays relevant to all GE events that contain these two genetic elements. Data are presented by testing two variations each of five published real-time quantitative PCR methods for 35S detection on eight maize reference materials. The results showed that two of the five methods were not suitable for all the eight reference materials, with poor linear regression parameters and multiple PCR amplification products for some of the reference materials. This study demonstrates that not all 35S methods produce satisfactory results, emphasizing the need for method validation. © 2009 Springer-Verlag.

Background Childhood overweight has been reported in developing countries. The World Health Organization (WHO) has recommended a standardized classification system in order to facilitate comparison across countries and studies. This study aims to assess the prevalence of overweight, obesity and thinness in a group of 10-11-year-old children using three references [the Center for Disease Control (CDC) 2000, the the International Obesity Task Force (IOTF) 2000 and the WHO, 2007]. MethodsA representative sample of 1588 children (771 boys and 817 girls) resulted from the randomization of 80 public schools from Buenos Aires. ResultsThe prevalence of overweight, including obesity, for the whole sample was 35.5, 27.9 and 27.9, respectively, depending on the reference used. For overweight, no gender differences were observed regardless of the reference used. Obesity was significantly more frequent among boys, and this remained consistent for the three references. Thinness frequency was 1.6 and 2.5 for the boys and 2.7 and 4.5 for the girls when considering the WHO and CDC cut-off points, respectively, and frequency increased in both boys and girls for each age group. ConclusionThere is a high prevalence of overweight and obese cases among school-aged children of Buenos Aires regardless of the reference used. Epidemiological data provided by this study suggests the urgent need to design preventive interventions. © The Author 2010, Published by Oxford University Press on behalf of Faculty of Public Health.

Objective Assess the efficacy of the components of school-based preventive interventions in improving the nutritional quality of children's intake, in increasing their time of physical activity (PA), and ultimately in reducing childhood obesity. Methods A review of the research literature published between 2009 -2014 was conducted. Inclusion criteria was: systematic reviews, meta-analysis or reports regarding the impact of recommendations and specific governmental policies as well as of randomized or non-randomized controlled, transversal and quasi-experimental trials with evaluations at 6 or more months after baseline that reported objectives measures of outcome. Results 25 scientific publication met inclusion criteria. Conclusions Although generalizability of results is limited by the heterogeneity of the studies, it appears that there is no evidence that a specific intervention component is more effective. Contrarily, multi-component programs, especially if they combine a change in quality intake together with an increase in PA seem to contribute to prevent childhood obesity. Evidence regarding regulation policies is non-conclusive and probably requires broader interventions that contemplate the socio-cultural context of the target population. © 2015 Universidad Nacional Autónoma de México, Facultad de Estudios Superiores Iztacala.
