Long chain polyunsaturated fatty acids (LCPUFA), especially docosahexaenoic acid (DHA), are the most abundant fatty acids in the brain and are necessary for growth and maturation of the brain and retina. LCPUFA are named "essential" because they cannot be synthesised efficiently by the human body and come from maternal diet. It remains controversial whether LCPUFA supplementation to breastfeeding mothers is beneficial for the development of their infants. To assess the effectiveness and safety of supplementation with LCPUFA in breastfeeding mothers in the cognitive and physical development of their infants as well as safety for the mother and infant. We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (November 2009), CENTRAL (2009, Issue 2), PubMed (1966 to July 2009), EMBASE (1974 to June 2009), CINAHL (1984 to June 2009), LILACS (1982 to June 2009), Google Scholar (June 2009) and reference lists of published narrative and systematic reviews. Randomised controlled trials or cluster-randomised controlled trials evaluating the effects of LCPUFA supplementation on breastfeeding mothers and their infants. Two review authors independently assessed eligibility and trial quality and performed data extraction. We included six randomised controlled trials involving 1280 women. We found no significant difference in children's neurodevelopment: language development (standardised mean difference (SMD) -0.14, 95% confidence interval (CI) -0.49 to 0.20; two trials, 349 participants); intelligence or problem-solving ability (two trials, 817 participants; SMD -0.22, 95% CI -0.23 to 0.66); psychomotor development (SMD 0.34, 95% CI -0.11 to 0.78; two trials, 279 participants); motor development (SMD 0.08, 95% CI -0.13 to 0.29; two trials, 349 participants); in child attention there was a significant difference (SMD 0.50, 95% CI 0.24 to 0.77; one study). For child visual acuity there was no significant difference (SMD -0.06, 95% CI -0.26 to 0.14; three trials, 401 participants). For growth, there were significant differences in length (MD -0.75 cm, 95% CI -1.38 to -0.12; two trials, 834 participants) and head circumference (MD 0.69 cm, 95% CI 0.35 to 1.02; one trial, 244 participants). One study reported a significant difference in infant allergy (risk ratio (RR) 0.12, 95% CI 0.02 to 0.95). We found no significant difference in one trial evaluating postpartum depression (SMD 0.15, 95% CI -0.11 to 0.41).   Based on the limited evidence that we found, LCPUFA supplementation did not appear to improve children's neurodevelopment or visual acuity. In two studies, LCPUFA supplementation was associated with increased head circumference. Currently, there is insufficient evidence to support or refute the practice of giving LCPUFA supplementation to breastfeeding mothers in order to improve infant growth and development.

Objective: The consumption of fruits and vegetables (FV) may contribute to the prevention of many diseases. However, children at school age do not eat an enough amount of those foods. We have systematically reviewed the literature to assess the effectiveness of school interventions for promoting the consumption of FV. Methods: We performed a search in MEDLINE, EMBASE, CINAHL and CENTRAL. We pooled results and stratified the analysis according to type of intervention and study design. Results: Nineteen cluster studies were included. Most studies did not describe randomization method and did not take the cluster's effect into account. Pooled results of two randomized controlled trials (RCTs) of computer-based interventions showed effectiveness in improving consumption of FV [Standardized Mean Difference (SMD) 0.33 (95% CI 0.16, 0.50)]. No significant differences were found in pooled analysis of seven RCTs of multicomponent interventions or pooling results of two RCTs evaluating free/subsidized FV interventions. Conclusions: Meta-analysis shows that computer-based interventions were effective in increasing FV consumption. Multicomponent interventions and free/subsidized FV interventions were not effective. Improvements in methodology are needed in future cluster studies. Although these results are preliminary, computer-based interventions could be considered in schools, given that they are effective and cheaper than other alternatives. © 2011 Elsevier Inc.

Sufficient epidemiologic evidence has established an etiologic link between bladder cancer risk and occupational exposure as a painter to organic solvents. Currently, it remains to be established whether gene-specific promoter methylation contributes to bladder cancer development, including by enhancing chromosome breakage or loss. We investigated the effect of chronic exposure to organic solvents and paints on DNA methylation profiles in the promoter regions of four genes (GSTP1, p16INK4a, APC and CDH1) and micronucleus (MN) frequency in exfoliated urothelial cells from voided urine from Colombian male non-smoking car painters and age-matched unexposed individuals. The exposed group had a higher percentage of individuals with >2 MNs/2000 cells compared with the unexposed group (P=0.04). Gene-specific analysis showed a significantly higher percentage of individuals with methylated GSTP1, p16INK4a and APC in the exposed group. Poisson regression analysis indicated that exposed individuals with methylated GSTP1 and p16INK4a promoters were more than twofold more likely to have an increase in MN frequency as compared with the reference. Finally, among exposed individuals with GSTP1 and p16INK4a methylated promoters, those with a greater age had a higher RR of increased MN frequency compared with younger exposed individuals with methylated promoters. These results support the conclusion that gene-specific promoter methylation may increase MN frequency in a dependent or independent interaction with occupational exposure to organic solvents.Journal of Exposure Science and Environmental Epidemiology advance online publication, 20 May 2015; doi:10.1038/jes.2015.28. © 2015 Nature America, Inc.

The second-to-fourth digit ratio (2D/4D) is a well-studied sexual dimorphism that likely arises as a result of prenatal androgenic effects on homeobox gene expression. This dimorphism has been found to exhibit interesting phylogenetic patterns in which females have larger ratios than males among most mammalian species and males have larger ratios than females in most avian and reptilian species. This study measured the second and fourth digits of all limbs from 25 adult males and 25 adult females of Gonatodes albogularis. There were no significant differences between the (2D/4D) for gender as sexual dimorphism of the species. These results indicate that this species of tree lizard deviates from the ratio shown by diapsid species. Possible associated environmental factors are discussed.

TUCAN3G is built upon the basic premise that considers information and communications as a key factor of human development. The diffusion of ICT in developing countries has been very asymmetric between densely populated urban areas and isolated rural areas. Geographical conditions have often conditioned solutions for Internet connectivity in rural areas, often based on wireless 2G cellular technologies. From a technological and socio-economical), this project proposes to study the introduction of 3G Femtocells (and its evolution to 4G) in outdoor environments, with backhauling heterogeneous WiLD (WiFi for Long Distances) - WiMAX - VSAT, to provide access to voice and data services to remote rural areas in developing countries. More specifically, the project aims to three specific objectives framed in: (SO1) technology development, (SO2) market research and elaboration of business models, and (SO3) in verification through proofs of concept in platforms installed in basins of the rivers Napo and Putumayo (Peru), which will allow deploying several femtocells in 4 remote rural locations. The technological objective (SO1) aims at optimizing access networks FWI (Femto-WiFi Integration) and heterogeneous transport networks WWVI (WiLD-WiMAX Integration VSAT) to provide 3G service to isolated rural populations in a progressive way . This objective will adopt interference management solutions studied in the ICT project FREEDOM (www.ict-freedom.eu) for the outdoor rural scenario and will introduce LIPA (IP Local Access) and SIPTO (Selected IP Traffic Offload) features to reduce the burden on the transport network. On its turn, optimal solutions for resource allocation and flow control for WiLD transport networks (WiFi parameterization for long distance and quality of service management) and VSAT (hard & soft acceleration) will be derived. In all cases we will consider the critical factors associated to the energy consumption.
