    Sleep enhances generalization in adults, but this has not been examined in toddlers. This study examined the impact of napping versus wakefulness on the generalization of word learning in toddlers when the contextual background changes during learning. Thirty 2.5-year-old children (M = 32.94, SE = 0.46) learned labels for novel categories of…

    Comprehensive evaluation of prior interventions designed to increase preschoolers' physical activity is lacking. This systematic review aimed to examine the effect of interventions on objectively measured physical activity in children aged 2-5 years. We followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement. In May 2014, we searched PubMed, CINAHL, PsycINFO, ERIC, SPORTDiscus, Cochrane, and Embase. Two reviewers independently identified and appraised the studies. Twenty-four articles describing 23 independent studies and 20 unique interventions met inclusion criteria. Of the 8 interventions resulting in a significant effect in objectively measured physical activity, all were center-based and included a structured physical activity component, 6 included multiple components, 5 integrated theories or models, and 4 actively involved parents. Seven of the 8 were randomized controlled trials. Due to the heterogeneity of the study designs, physical activity measures, and interventions, drawing definitive conclusions was difficult. Although the overall intervention effect was less than optimal, the review indicated that theory-driven, multicomponent interventions including a structured physical activity component and targeting both parents and their children may be a promising approach for increasing preschoolers' physical activity and warrant continued investigation using rigorous designs to identify those that are most effective.

    In typically developing children, drawing development occurs in stages from uncontrolled strokes to complex drawing. In this study, we examined drawing development in children with neurodevelopmental delay (NDD). In order to do so, we observed the influence of age, intraventricular hemorrhage (IVH) and gender on the development of drawing skills. The sample consisted of 52 children with NDD, aged 2 years and 6 months to 5 years. All children were hospitalized for multidisciplinary team monitoring and developmental support. The evaluation of drawing development was administered by giving each child a blank A4 paper and the instruction to draw anything they wanted. All of the drawings were scored satisfactory or unsatisfactory. Descriptive statistics was employed on all relevant data to show results in frequencies and percentages. In order to determine differences between groups, the χ2-test was administered. The results showed greatest difference in drawing in children aged from 3 years to 3 years and 11 months. Children with lower IVH had better drawing scores than children with higher IVH levels. According to gender dissimilarities, a difference was found showing girls to have better drawing skills than boys. All study results pointed to the importance of early rehabilitation and continuous structured work with children with NDD.

    By 3 years of age, children can solve tasks involving physical principles such as locating a ball that rolled down a ramp behind an occluder by the position of a partially visible solid wall (Berthier, DeBlois, Poirer, Novak, & Clifton, 2000; Hood, Carey, & Prasada, 2000). However, the extent to which children use physical information (the properties of the wall) remains unclear because spatial information would suffice (the location of the wall in relation to the ball). We confronted 2- to 6-year-old children with a ball resting on a shelf inside a clear plastic-fronted box. To retrieve the ball, children had to roll it away from a trap or barrier using their fingers. Crucially, a single object acted as a barrier or supporting surface in different conditions, thus requiring a flexible response. Preschoolers solved the task and the critical transfers from 2.5 years of age (Study 1). Interestingly, 2.5-year-olds required to use a tool to displace the ball performed significantly worse than those who could use their fingers (Study 2). In contrast, 2.5- to 4.5-year-olds failed a covered trap box that provided only 2-dimensional predictive cues without any visible physical information, and even 6.5-year-olds performed significantly worse on the covered task compared to the uncovered one (Studies 3 and 4). Our results suggest that children from around 2.5 years of age integrate spatial and physical information when solving problems like the trap box task, rather than simply exploit spatial relationships between features.

    The prevalence of dental caries was determined clinically in 2.5-year-old Dutch cleft lip and/or palate children (n = 76) and in children without congenital malformation (n = 75). The parents were given a structured questionnaire regarding the child's dietary habits, oral hygiene, fluoride exposure and social economic background. The prevalence of dental caries was higher in children with oral cleft than in children without oral cleft. Initial caries (white spots) was diagnosed in 17.1% of the subjects with oral cleft compared with 4.0% of the control subjects. Manifest caries (cavities) was found in 26.3% of the children with oral cleft compared with 5.3% of the controls. The dft score (manifest caries) was significantly higher for the oral cleft group (0.59 +/- 1.35) than for the control group (0.11 +/- 0.54). 52% of the total number of initial and manifest lesions were localized to the maxillary incisors. A multivariate analysis yielded initial caries, oral hygiene and treatment with preoperative infant orthopaedics as the variables significantly associated with manifest caries.

    We assessed the effect of a selected intervention on the nutritional status of 2-5-year-old children in day care centres. Using a longitudinal prospective pretest/post-test intervention design, 974 children from 3 day care centres in Alexandria were followed for 1 year. Anthropometric measurements and 3-day 24-hour recall data were gathered at base line and dietary intake was calculated and compared with recommended daily allowances. An intervention programme was implemented through the establishment of kitchens in the 3 centres, provision of 2 meals/day, nutrition education for parents and training of supervisors. Baseline data revealed deficient intake of most nutrients especially calcium, calories, vitamin C and iron. Post-intervention test revealed improvement in mothers' nutrition knowledge and the percentage of anaemic children decreased from 47.3% to 14.2%. A decrease in the percentage of underweight, stunted and wasted was also observed. The cost of the programme per child per year was US$ 20.5.

    Background Previous research has stressed the importance of early identification and intervention for children with autism spectrum disorders. Methods Children who had screened positive for autism at the age of 2.5 years in a general population screening and then received a diagnosis of autism spectrum disorder were enrolled in an intervention program provided by Swedish habilitation services. The following interventions were available: a comprehensive intervention based on Applied Behavior Analysis – Intensive Learning (IL) – in two settings, which included home- and preschool-based (IL Regular) and only home-based (IL Modified) and eclectic interventions. Results There was considerable variability in terms of outcome, but intervention group status was not associated with any of the chosen outcome variables. Conclusion The main finding was that the type of intervention was not critical for outcome of adaptive or global functioning. The variability in outcome demonstrates the need for continuous assessments and evaluation of the child’s function and behavior throughout the intervention period. PMID:27621636

    A cross-sectional study was carried out on Bahraini preschoolers aged 2-5 years (354 males and 344 females) to determine the prevalence of overweight and obesity using the World Health Organization and the International Obesity Task Force cut-off values. Weight and height were recorded and body mass index (BMI) was calculated to determine the proportion of overweight and obesity. Using the World Health Organization percentile cut-off values, overweight (12.3%) and obesity (8.4%) was higher in females between 2 and <4 years of age whereas, the proportion of both overweight (8.4%) and obesity (7.2%) were higher in males between 4 and <6 years of age. Relative to the International Obesity Task Force indicators, the World Health Organization cut-off values produced nearly a 2-fold increase in both overweight and obesity at most ages. It is therefore important to ensure that the same cut-off reference values are used to define overweight and obesity particularly in preschoolers. Shifting to the new World Health Organization child growth standards may have important implications for child health programmes.

    Caudate nucleus volume is enlarged in autism spectrum disorder (ASD) and is associated with restricted and repetitive behaviors (RRBs). However, the trajectory of caudate nucleus volume in RRBs of young children remains unclear. Caudate nucleus volume was measured in 36 children with ASD and 18 matched 2-3-year-old subjects with developmentally delayed (DD) at baseline (Time 1) and at 2-year follow-up (Time 2). The differential growth rate in caudate nucleus volume was calculated. Further, the relationships between the development of caudate nucleus volume and RRBs were analyzed. Our results showed that caudate nucleus volume was significantly larger in the ASD group at both time points and the magnitude of enlargement was greater at Time 2. The rate of caudate nucleus growth during this 2-year interval was faster in children with ASD than DD. Right caudate nucleus volume growth was negatively correlated with RRBs. Findings from this study suggest developmental abnormalities of caudate nucleus volume in ASD. Longitudinal MRI studies are needed to explore the correlation between atypical growth patterns of caudate nucleus and phenotype of RRBs.

    Dental caries is a multifactorial disease that includes behavioral and cultural components. The study's purpose was to determine the caries experienced (as measured by dmft) in a group of 2-5 y/o children, assess their family and home environment including consumption of fluoridated drinking water, use of a fluoride containing dentifrice, and level of caregiver formal education. Parents of children referred for dental treatment under general anesthesia and who either spoke and read English or Spanish were recruited and consent obtained. Selected information on the family home, parental education and selected fluoride contact data was obtained. An oral clinical examination of the child assisted by intraoral radiographs was completed and the number of decayed, missing, filled primary teeth (dmft) recorded for each child. Bitewings were obtained if posterior or anterior teeth contacts were closed but only periapical radiographs were obtained if contacts were open. Children of English speaking caregivers had statistically more dmft after controlling for the effect of the child's age and years of parental education (p=0.04). English speaking families had lived in their current home longer and the parent had more formal education than did the Spanish speaking parent. When available, the English children drank municipal tap water more often than did the Spanish children. Spanish speaking parents often chose bottled drinking water. No difference between the two groups was found in the use of tap water for cooking or the use of fluoridated dentifrice. In conclusion, increased parent education, language spoken by the parents and time living in the current home were not associated with lower dmft. Drinking fluoridated drinking water did not affect the dmft. However, using fluoridated water when available to cook and using fluoride containing dentifrice by both groups may have been mutually beneficial.

    Group-based competition is considered to be a ubiquitous social context in human society. However, little is known about its potential effects on children's prosocial behaviors. To this end, we designed an experiment in which two age groups (2.5-3.5 years of age and 5.5-6.5 years of age) engaged in an intergroup competition task where they did a so-called "game" where each child transferred table tennis balls with a spoon from one container to the other. The non-intergroup competition condition was identical to the intergroup competition condition with one exception-no intergroup competition manipulation was involved. Then, they were required to perform two economic games used to measure their prosocial behaviors. We found that under the non-intergroup competition condition, as children aged, their behaviors tended to be more fairness-oriented (such as an increase in egalitarian behaviors). However, under the intergroup competition condition, children at 2.5-3.5 years of age tended to behave prosocially towards their ingroup members compared with those who are at 5.5-6.5 years of age. The behavioral pattern under the intergroup competition condition reflects strengthening prosocial tendencies driven by the intergroup competition in younger children and simultaneously weakening intergroup competition-driven prosocial tendencies possibly due to the development of fairness-oriented behaviors in older children. Taken together, these results point to the importance of considering the effects of competitive contexts on children's social behaviors and may have important implications for further research on the role of competitive contexts in the development of human prosocial behaviors.

    Objectives It is not known which sports are most likely to cause overuse injuries of the extremities in children. In this study, we report on the incidence of overuse injuries of the upper and lower extremities in children who participate in various leisure-time sports and relate this to the frequency of sport sessions. Design Natural experiment including a prospective cohort study. Setting 10 state schools in 1 Danish municipality: Svendborg. Participants 1270 children aged 6–13 years participating in the Childhood Health, Activity, and Motor Performance School Study Denmark. Outcomes measures Over 2.5years, parents answered weekly SMS-track messages (a) on type and frequency of leisure-time sports undertaken by their child, and (b) reporting if their child had experienced any musculoskeletal pain. Children with reported pain were examined by a clinician and diagnosed as having an overuse injury of an extremity or not. The incidence of diagnosed overuse injury was calculated for each of the 9 most common sports in relation to 5-week periods. Incidence by frequency of sessions was calculated, and multivariable analysis was performed taking into account age, sex and frequency of physical education classes at school. Results Incidence of overuse injuries of the lower extremity ranged from 0.2 to 3.3 for the 9 sports, but was near 0 for overuse injuries of the upper extremities. There was no obvious dose–response. The multivariate analysis showed soccer and handball to be the sports most likely to result in an overuse injury. Conclusions Among a general population of schoolchildren, overuse injuries of the lower extremities were not common and overuse injuries of the upper extremities were rare. Organised leisure-time sport, as practised in Denmark, can be considered a safe activity for children. PMID:28087543

    The tolerability of a 2.5% lidocaine/prilocaine hydrogel (Nanorap, Biolab Indústria Farmacêutica Ltd., Sao Paulo, Brazil) was evaluated in 20 children ages 2 to 11 years undergoing cryotherapy for molluscum contagiosum (MC). The product was well tolerated, with only two children presenting with eczema at the application site. These adverse reactions were considered unlikely to be related to the test product, because a patch test was negative in one of the individuals and the other event occurred in only one of the two treated areas. Nanorap is an efficacious and well-tolerated option for topical anesthesia in children undergoing cryotherapy for MC.

    The Attachment Insecurity Screening Inventory (AISI) 2-5 years is a parent-report questionnaire for assessing attachment insecurity in preschoolers. Validity and reliability of the AISI 2-5 years were examined in a general sample (n = 429) and in a clinical sample (n = 71). Confirmatory factor analysis (CFA) confirmed a three-factor model of avoidant, ambivalent/resistant and disorganized attachment, and one higher-order factor of total attachment insecurity. Multi-group CFA indicated measurement invariance across mothers and fathers, and across the general and clinical population sample. Reliability coefficients were generally found to be good. We found partial support for convergent validity in associations between AISI-scores and observed attachment (AQS). Concurrent validity was supported by associations between AISI-scores and observed parental sensitivity (MBQS) and parent-reported psychopathology (SDQ). Finally, the AISI discriminated well between children from the general and from the clinical sample. We argue that both research and practice could benefit from the AISI as there is now a prospect of quickly, reliably and validly screening for attachment insecurity in pre-school aged children. Based on this information, help can be offered timely and, subsequently, the prevention of attachment related problems of children can be strengthened.

  2. Discourse prominence effects on 2.5-year-old children’s interpretation of pronouns

    2007-01-01

    Three experiments examined 2.5-year-olds’ sensitivity to discourse structure in pronoun interpretation. Children heard simple two-character stories illustrated by pictures on two video screens. In Experiments 1 and 2, one character in each story was established as more prominent than the other in several context sentences because it was mentioned first, appeared in subject position, was mentioned more often, and was pronominalized once. In Experiment 3, one character was singled out as more prominent only by being mentioned first and placed in subject position. In all three experiments, after hearing a pronoun subject in the final (test) sentence of each story, children looked longer at the character established as more prominent in the preceding sentences. These experiments show that 2.5-year-olds, like older children and adults, interpret pronouns relative to a discourse representation in which referents are ranked in prominence, and that the prominence of discourse referents is influenced by some of the same factors that guide pronoun interpretation in adulthood.

    The aim of this study was to link the concentrations of particulate matter with an aerodynamic diameter below 2.5 μm (PM2.5) and associated heavy metals with occurrence of wheezing and hospitalizations due to wheezing in 111 children who live near metallurgical plants in Targoviste City, Romania. A group of 72 children with high levels of immunoglobulin E (IgE) and eosinophils, as well as frequent wheezing episodes, was geolocated on digital thematic maps. Monitoring campaigns and medical assessments were performed over two consecutive years (2013-2014). The multiannual average concentrations of PM2.5 ranged from 4.6 to 22.5 μg m(-3), up to a maximum value of 102 μg m(-3). Significant correlations (p < 0.01) were observed between the locations of the children with respiratory issues and the PM2.5 multiannual average (r = 0.985) and PM2.5 maximum (r = 0.813). Fe, Ni, Cd, and Cr were the main marker elements of the emissions from steel production and metal-working facilities in the Targoviste area. The results support the hypothesis that increased PM2.5 levels directly influence wheezing symptom and asthma attacks in the analyzed group. IgE, eosinophils, and wheezing episodes may be considered key indicators with which to evaluate the adverse effects of PM2.5 air pollution on children's health.

    2014-01-01

    Background High television exposure time at young age has been described as a potential risk factor for developing behavioral problems. However, less is known about the effects of preschool television on subsequent bullying involvement. We examined the association between television viewing time through ages 2-5 and bullying involvement in the first grades of elementary school. We hypothesized that high television exposure increases the risk of bullying involvement. Method TV viewing time was assessed repeatedly in early childhood using parental report. To combine these repeated assessments we used latent class analysis. Four exposure classes were identified and labeled “low”, “mid-low”, “mid-high” and “high”. Bullying involvement was assessed by teacher questionnaire (n = 3423, mean age 6.8 years). Additionally, peer/self-report of bullying involvement was obtained using a peer nomination procedure (n = 1176, mean age 7.6 years). We examined child risk of being a bully, victim or a bully-victim (compared to being uninvolved in bullying). Results High television exposure class was associated with elevated risks of bullying and victimization. Also, in both teacher- and child-reported data, children in the high television exposure class were more likely to be a bully-victim (OR = 2.11, 95% CI: 1.42-3.13 and OR = 3.68, 95% CI: 1.75-7.74 respectively). However, all univariate effect estimates attenuated and were no longer statistically significant once adjusted for maternal and child covariates. Conclusions The association between television viewing time through ages 2-5 and bullying involvement in early elementary school is confounded by maternal and child socio-demographic characteristics.

    The objective of this study was to determine the association of respiratory symptoms and medication use and exposure to various air pollutants, PM2.5 components, and source factors in a panel of asthmatic and nonasthmatic children in Santiago, Chile. To this end, 174 children (90 asthmatics and 84 nonasthmatics) were followed throughout the winter months of 2010 and 2011. During the study period, children filled out daily diaries to record respiratory symptoms and medication use. Air pollution data were obtained from government central site measurements and a PM2.5 characterization campaign. PM2.5 source factors were obtained using positive matrix factorization (PMF). Associations of symptoms and exposure to pollutants and source-factor daily scores were modeled separately for asthmatic and nonasthmatic children using mixed logistic regression models with random intercepts, controlling for weather, day of the week, year, and viral outbreaks. Overall, high concentrations of air pollutants and PM2.5 components were observed. Six source factors were identified by PMF (motor vehicles, marine aerosol, copper smelter, secondary sulfates, wood burning, and soil dust). Overall, single pollutant models showed significant and strong associations between 7-day exposures for several criteria pollutants (PM2.5, NO2, O3), PM2.5 components (OC, K, S, Se, V), and source factors (secondary sulfate) and coughing, wheezing and three other respiratory symptoms in both in asthmatic and nonasthmatic children. No associations were found for use of rescue inhalers in asthmatics. Two-pollutant models showed that several associations remained significant after including PM2.5, and other criteria pollutants, in the models, particularly components and source factors associated with industrial sources. In conclusion, exposure to air pollutants, especially PM2.5, NO2, and O3, were found to exacerbate respiratory symptoms in both asthmatic and nonasthmatic children. Some of the results suggest

    Increased ADHD symptomology and lower IQ have been reported in internationally adopted (IA) children compared to non-adopted peers (Hostinar et al., 2013; Kreppner, O’Connor, & Rutter, 2001). However, it is unclear whether these outcomes are due to institutional deprivation specifically or to co-occurring micronutrient deficiencies that disrupt brain development (Fuglestad et al., 2008). In this study, IA children were compared to children raised in their biological families to examine differences in ADHD symptomology and IQ 2.5-5 years post-adoption and to assess the contributions of iron deficiency (ID) and duration of deprivation to these cognitive outcomes. ADHD symptoms (parent- and experimenter-reported) and IQ were evaluated in 88 IA (M= 62.1 months, SD = 2.4) and 35 non-adopted children (M= 61.4 months, SD = 1.6). IA children were assessed 29-64 months post-adoption (M = 41.9 months, SD = 10.2). ID was assessed during the initial post-adoption medical visit in 69 children, and children were classified into 4 groups by iron status, ranging from normal to ID anemia (most severe). IA children had greater ADHD symptomology, p < .01, and lower IQ, p = .001, than non-adopted children. Within the IA group, children with more severe ID at adoption had greater ADHD symptomology, r(69) = 0.40, p = .001, and lower IQ, r(68) = −0.28, p < .05. Duration of institutional care was positively correlated with ADHD symptoms, r(86) = .28, p < .01, but not IQ, r(85) = −.08, p = .52. Longitudinal results indicate improvement in IQ from 12 months post-adoption to age 5 for children with greater ID severity at adoption and longer duration of institutional care but no improvement in ADHD symptoms. These results signify continuing effects of early deprivation and ID on ADHD symptoms and IQ years after adoption. PMID:25070881

    The seasonal and spatial characteristics of PM2.5 and its chemical composition in the Mediterranean Basin have been studied over a 1-year period (2011-2012) in five European Mediterranean cities: Barcelona (BCN), Marseille (MRS), Genoa (GEN), Venice (VEN), and Thessaloniki (THE). During the year under study, PM10 annual mean concentration ranged from 23 to 46 μg m- 3, while the respective PM2.5 ranged from 14 to 37 μg m- 3, with the highest concentrations observed in THE and VEN. Both cities presented an elevated number of exceedances of the PM10 daily limit value, as 32% and 20% of the days exceeded 50 μg m- 3, respectively. Similarly, exceedances of the WHO guidelines for daily PM2.5 concentrations (25 μg m- 3) were also more frequent in THE with 78% of the days during the period, followed by VEN with 39%. The lowest PM levels were measured in GEN. PM2.5 exhibited significant seasonal variability, with much higher winter concentrations for VEN and MRS, in fall for THE and in spring for BCN. PM2.5 chemical composition was markedly different even for similar PM2.5 levels. On annual average, PM2.5 was dominated by OM except in THE. OM contribution was higher in Marseille (42%), while mineral matter was the most abundant constituent in THE (32%). Moreover, PM2.5 relative mean composition during pollution episodes (PM2.5 > 25 μg m- 3) as well as the origins of the exceedances were also investigated. Results outline mainly the effect of NO3- being the most important driver and highlight the non-negligible impact of atmospheric mixing and aging processes during pollution episodes.

    Increased ADHD symptomology and lower IQ have been reported in internationally adopted (IA) children compared to non-adopted peers (Hostinar, Stellern, Schaefer, Carlson & Gunnar, 2012; Kreppner, O'Connor & Rutter, 2001). However, it is unclear whether these outcomes are due to institutional deprivation specifically or to co-occurring micronutrient deficiencies that disrupt brain development (Fuglestad, Rao & Georgieff, 2008b). In this study, IA children were compared to children raised in their biological families to examine differences in ADHD symptomology and IQ 2.5-5 years post-adoption and to assess the contributions of iron deficiency (ID) and duration of deprivation to these cognitive outcomes. ADHD symptoms (parent- and experimenter-reported) and IQ were evaluated in 88 IA (M = 62.1 months, SD = 2.4) and 35 non-adopted children (M = 61.4 months, SD = 1.6).

Longitudinal results indicate improvement in IQ from 12 months post-adoption to age 5 for children with greater ID severity at adoption and longer duration of institutional care but no improvement in ADHD symptoms. These results signify continuing effects of early deprivation and ID on ADHD symptoms and IQ years after adoption.

  9. Increased subaerial volcanism and the rise of atmospheric oxygen 2.5 billion years ago.

    The hypothesis that the establishment of a permanently oxygenated atmosphere at the Archaean-Proterozoic transition (approximately 2.5 billion years ago) occurred when oxygen-producing cyanobacteria evolved is contradicted by biomarker evidence for their presence in rocks 200 million years older. To sustain vanishingly low oxygen levels despite near-modern rates of oxygen production from approximately 2.7-2.5 billion years ago thus requires that oxygen sinks must have been much larger than they are now. Here we propose that the rise of atmospheric oxygen occurred because the predominant sink for oxygen in the Archaean era-enhanced submarine volcanism-was abruptly and permanently diminished during the Archaean-Proterozoic transition. Observations are consistent with the corollary that subaerial volcanism only became widespread after a major tectonic episode of continental stabilization at the beginning of the Proterozoic. Submarine volcanoes are more reducing than subaerial volcanoes, so a shift from predominantly submarine to a mix of subaerial and submarine volcanism more similar to that observed today would have reduced the overall sink for oxygen and led to the rise of atmospheric oxygen.

  10. Performance of the MIR Cooperative Solar Array After 2.5 Years in Orbit

    1999-01-01

    The Mir Cooperative Solar Array (MCSA) was developed jointly by the United States and Russia to produce 6 kW of power for the Russian space station Mir. Four, multi-orbit test sequences were executed between June 1996 and December 1998 to measure MCSA electrical performance. A dedicated Fortran computer code was developed to analyze the detailed thermal-electrical performance of the MCSA. The computational performance results compared very favorably with the measured flight data in most cases. Minor performance degradation was detected in one current generating section of the MCSA. Yet overall, the flight data indicated the MCSA was meeting and exceeding performance expectations. There was no precipitous performance loss due to contamination or other causes after 2.5 years of operation. In this paper, we review the MCSA flight electrical performance tests, data and computational modeling and discuss findings from data comparisons with the computational results.

    The Oldowan Stone tool industry was named for 1.8-million-year-old (Myr) artefacts found near the bottom of Olduvai Gorge, Tanzania. Subsequent archaeological research in the Omo (Ethiopia) and Turkana (Kenya) also yielded stone tools dated to 2.3 Myr. Palaeoanthropological investigations in the Hadar region of the Awash Valley of Ethiopia, revealed Oldowan assemblages in the adjacent Gona River drainage. We conducted field work in the Gona study area of Ethiopia between 1992 and 1994 which resulted in additional archaeological discoveries as well as radioisotopic age control and a magnetic polarity stratigraphy of the Gona sequence. These occurrences are now securely dated between 2.6-2.5 Myr. The stone tools are thus the oldest known artefacts from anywhere in the world. The artefacts show surprisingly sophisticated control of stone fracture mechanics, equivalent to much younger Oldowan assemblages of Early Pleistocene age. This indicates an unexpectedly long period of technological stasis in the Oldowan.

    Background Technological advances have made it easier for researchers to collect more frequent longitudinal data from survey respondents via personal computers, smartphones, and other mobile devices. Although technology has led to an increase in data-intensive longitudinal studies, little is known about attrition from such studies or the differences between respondents who complete frequently administered surveys in a timely manner, and respondents who do not. Objective We examined respondent characteristics and behaviors associated with continued and on-time participation in a population-based intensive longitudinal study, using weekly web-based survey interviews over an extended period. Methods We analyzed data from the Relationship Dynamics and Social Life study, an intensive longitudinal study that collected weekly web-based survey interviews for 2.5 years from 1003 18- and 19-year-olds to investigate factors shaping the dynamics of their sexual behavior, contraceptive use, and pregnancies. Results Ordinary least squares and logistic regression analyses showed background respondent characteristics measured at baseline were associated with the number of days respondents remained enrolled in the study, the number of interviews they completed, and the odds that they were late completing interviews. In addition, we found that changes in pregnancy-related behaviors reported in the weekly interviews were associated with late completion of interviews. Specifically, after controlling for sociodemographic, personality, contact information, and prior experience variables, we found that weekly reports such as starting to have sex (odds ratio [OR] 1.17, 95% CI 1.03-1.32, P=.01), getting a new partner (OR 1.76, 95% CI 1.53-2.03, P<.001), stopping the use of contraception (OR 1.28, 95% CI 1.10-1.49, P=.001), and having a new pregnancy (OR 5.57, 95% CI 4.26-7.29, P<.001) were significantly associated with late survey completion. However, young women who reported changes in

    Humans are exposed to health-impairing air pollutants, especially children who are more sensitive to cancer-causing toxins. This study described an area of reference for inhalable particulates (PM2.5) by chemical (polycyclic aromatic hydrocarbons) and mutagenic characterization associated with the genetic biomonitoring of children (aged 5-11 years). The area studied was in a small town in Brazil, used as reference in previous studies. Organic matter of PM2.5 (extracted with dichloromethane) was evaluated for mutagenesis in a Salmonella/microsome (microsuspension) assay, in strains measuring frameshift error (TA98, YG1021 and YG1024) and base pair substitution (TA100) of DNA, in the presence and absence of rat liver metabolization fraction (S9). Exposure was studied analyzing a sample of 45 children using comet assay (peripheral blood lymphocytes) and micronucleus (exfoliated buccal mucosa cells). PM2.5 concentration for the period was 9% (25.89-64.71 μg/m3) events above WHO limit value (25 μg/m3). Mutagenesis responses (revertants/m3) varied from negative (spring) to 8.3±0.69 (autumn) (-S9) and 5.4±0.36 (winter) (+S9), in strain TA98, and for TA100, in spring, from negative to 14.8±4.23 (-S9) and 17.5±2.72 (+S9). YG strain results show mononitroarenes and aromatic amines. Mean biomonitoring values were established for MN, 0.3±0.41 (‰) and for other cell types a variation from 0.6±0.73 (‰), nuclear buds to 57.5±24.92 (‰), karyorrhexis. Comet assay means were 23.1±12.44; 7.3±11.66 and 0.9±2.30 for tail length, intensity and moment, respectively. There was no difference for sex and age for the different parameters. A significant difference in confounding factors was observed for passive smoking and MN induction. PAHs and mutagenesis in the air may be related to local vehicular emissions. These results challenge the definition of areas of reference for air pollution associated with human biomonitoring including the region studied.

    experimentally verify some intuitive results: weather regimes associated with weak (resp. high) precipitation, wind and low (resp. high) temperatures correspond to higher (resp. lower) PM2.5 concentrations. We also observe that rain rate is the variable that impacts PM2.5 concentrations the most. Next, we search for better relationships by adding this second variable to the classification: we therefore build new weather regimes, called weather types. Because of the low number of the EMEP observations, we compute PM2.5 concentrations with the Polyphemus/Polair3D CTM for years between 2000 and 2008 in order to obtain a spatially and temporally complete dataset of PM2.5 concentrations and chemical components, which can be used to relate PM2.5 concentrations to meteorological regimes and specific variables. By classifying both a large-scale variable and a local variable that influence the PM2.5 concentrations and using gridded data of the modeled concentrations of PM2.5, we obtain a more robust analysis. The results of this work will provide the basis to predict the effects of climate change (via the evolution of weather regimes/types frequencies) on PM2.5 chemical composition and concentrations.

    The Archean Kolar Schist Belt, south India, is a suture zone where two gneiss terranes and at least two amphibolite terranes with distinct histories were accrted. Amphibolites from the eastern and western sides of the schist belt have distinct incompatible element and isotopic characteristics sugesting that their volcanic protoliths were derived from dint mantle sources. The amphibolite and gneiss terranes were juxtaposed by horizontal compression and shearing between 2530 and 2420 million years ago (Ma) along a zone marked by the Kolar Schist Belt. This history of accretion of discrete crustal terranes resembles those of Phanerozoic convergent margins and thus suggests that plate tectonics operated on Earth by 2500 Ma.

    Uranium-lead isotopic data indicate that the granulite-facies Napier complex of Enderby Land, Antarctica, was cut by charnockitic pegmatites 2.5 billion years ago and by pegmatites lacking hypersthene 0.52 billion years ago. The 4-bil-lion-years lead-lead ages (whole rock) reported for the Napier complex are rejected since these leads developed in three stages. Reconstructions of Gondwanaland suggest that the Napier complex may be a continuation of the Archean granulitic terrain of southern India.

    Background: In cranial reconstruction, the features of artificial bone differ. Custom-made porous hydroxyapatite (HAp) implants for cranioplasty have been used all over the world because of their good cosmetic, biocompatibility, and osteoconductive properties. Surgical techniques were analyzed, and histological assessment of new bone formation in the hydroxyapatite was performed. Methods: Over a 6-year time period, 41 patients underwent cranioplasty using a custom-made three-dimensional hybrid pore structured hydroxyapatite (3DHPoHAp) implant. The surgical techniques and histological evaluations of 3DHPoHAp in 2 cases, removed 6 months and 2.5 years after cranioplasty, are described. Results: Using 3DHPoHAp, cranioplasty was successfully performed for all patients. The implant fit the bone defect exactly, and surgical manoeuvres were simple and easy. All implants were firmly fixed using a titanium plate, and postoperative infection occurred in 1 patient (2.4%). New bone formation was seen in 2 cases 6 months and 2.5 years after cranioplasty. Osteoblasts were progressing to the stoma at various depths, and bone tissue had ripened. Furthermore, lamellar structure was observed in the case at 2.5 years. Conclusions: In this study, there was a low infection rate, and new bone formation was seen in vivo after cranioplasty. This study also demonstrated that the 3DHPoHAp implant is a good candidate for cranial bone implants because its good osteoconductivity and biocompatibility. PMID:28217387

    The incidence of malnutrition is widely held to be greater in the elderly, but this specific factor has not been extensively studied in elderly dialysis patients. In a 30-month follow-up prospective study, we evaluated the role of nutrition on the outcome of 290 stable hemodialysis (HD) outpatients aged older than 75 years followed up in 20 French HD centers (167 men, 123 women; age, 79.8 +/- 4.2 years; previous time on dialysis, 41 +/- 38 months). On the same day in January 1996, predialysis and postdialysis blood samples were collected according to recommended procedures for dialysis quantification. Normalized protein catabolic rate, dialysis adequacy parameters, and estimation of lean body mass (LBM; expressed as observed/expected LBM values [obs/exp LBM]) were computed from predialysis and postdialysis urea and creatinine levels. Overall survival rates were 80% and 65% after 1 and 2 years of follow-up, respectively, and were significantly less in patients with the lower quartile of obs/exp LBM. In univariate analysis using the Cox proportional hazards model, survival was significantly influenced by age, albumin level, prealbumin level, body mass index, and diabetes, but not by sex, Kt/V, duration of dialysis, cholesterol level, hemoglobin level, or obs/exp LBM. In multivariate analysis, no variable remained significant. Cardiovascular mortality accounted for 52.1% of the patient deaths. We conclude that in elderly HD patients, malnutrition influences overall survival despite adequate dialysis treatment.

    Personal exposure to particulate matter of aerodynamic diameter under 2.5 μm (PM 2.5) was monitored using a DustTrak nephelometer. The battery-operated unit, worn by an adult individual for a period of approximately one year, logged integrated average PM 2.5 concentrations over 5 min intervals. A detailed time-activity diary was used to record the experimental subject's movement and the microenvironments visited. Altogether 239 days covering all the months (except April) were available for the analysis. In total, 60 463 acceptable 5-min averages were obtained. The dataset was divided into 7 indoor and 4 outdoor microenvironments. Of the total time, 84% was spent indoors, 10.9% outdoors and 5.1% in transport. The indoor 5-min PM 2.5 average was higher (55.7 μg m -3) than the outdoor value (49.8 μg m -3). The highest 5-min PM 2.5 average concentration was detected in restaurant microenvironments (1103 μg m -3), the second highest 5-min average concentration was recorded in indoor spaces heated by stoves burning solid fuels (420 μg m -3). The lowest 5-min mean aerosol concentrations were detected outdoors in rural/natural environments (25 μg m -3) and indoors at the monitored person's home (36 μg m -3). Outdoor and indoor concentrations of PM 2.5 measured by the nephelometer at home and during movement in the vicinity of the experimental subject's home were compared with those of the nearest fixed-site monitor of the national air quality monitoring network. The high correlation coefficient (0.78) between the personal and fixed-site monitor aerosol concentrations suggested that fixed-site monitor data can be used as proxies for personal exposure in residential and some other microenvironments. Collocated measurements with a reference method (β-attenuation) showed a non-linear systematic bias of the light-scattering method, limiting the use of direct concentration readings for exact exposure analysis.

    China is virtually shut down during the week-long Chinese New Year's holiday. This implies that the anthropogenic emissions would be greatly decreased during the period thus providing an opportunity to study the air quality in China under reduced emissions, and the drastic emission changes during a short period of time allows the comparison of source contributions under significantly different conditions. Seventeen PM2.5 samples were collected during the 2009 Chinese New Year's holiday in Shanghai to study the composition and sources of the fine particles. Organic carbon (OC), elemental carbon (EC), eight water-soluble ions, fourteen metals and solvent extractable organic compounds (SEOC) including alkanes, hopanes, polycyclic aromatic hydrocarbons (PAHs) and fatty acids were measured. Diagnostic PAH ratios, correlation analysis of OC, EC, n-alkanes, hopanes and PAHs showed that vehicle emissions were the main source of n-alkanes and EC, and an important source of the locally emitted particulate PAHs in urban Shanghai, while coal burning should be the main source of the transported PAHs from the inland areas. The composition of n-fatty acids also provided some clue on the significance of the contribution by kitchen activities. In the New Year's Eve's sample, 75% of the particle mass was estimated to be from fireworks, and K+, SO42 -, Cl-, OC, Al and Ba were the main components. Firework fine particles had high OC/EC ratio and low NO3-/SO42 - ratio.

    The ages of the most common stars--low-mass (cool) stars like the Sun, and smaller--are difficult to derive because traditional dating methods use stellar properties that either change little as the stars age or are hard to measure. The rotation rates of all cool stars decrease substantially with time as the stars steadily lose their angular momenta. If properly calibrated, rotation therefore can act as a reliable determinant of their ages based on the method of gyrochronology. To calibrate gyrochronology, the relationship between rotation period and age must be determined for cool stars of different masses, which is best accomplished with rotation period measurements for stars in clusters with well-known ages. Hitherto, such measurements have been possible only in clusters with ages of less than about one billion years, and gyrochronology ages for older stars have been inferred from model predictions. Here we report rotation period measurements for 30 cool stars in the 2.5-billion-year-old cluster NGC 6819. The periods reveal a well-defined relationship between rotation period and stellar mass at the cluster age, suggesting that ages with a precision of order 10 per cent can be derived for large numbers of cool Galactic field stars.

    Introduction. On May 22, 2011 the deadliest tornado in the United States since 1947 struck Joplin, Missouri killing 161 people, injuring approximately 1,150 individuals, and causing approximately $2.8 billion in economic losses. Methods. This study examined the mental health effects of this event through a random digit dialing sample (N = 380) of Joplin adults at approximately 6 months post-disaster (Survey 1) and a purposive convenience sample (N = 438) of Joplin adults at approximately 2.5 years post-disaster (Survey 2). For both surveys we assessed tornado experience, posttraumatic stress, depression, mental health service utilization, and sociodemographics. For Survey 2 we also assessed social support and parent report of child strengths and difficulties. Results. Probable PTSD relevance was 12.63% at Survey 1 and 26.74% at Survey 2, while current depression prevalence was 20.82% at Survey 1 and 13.33% at Survey 2. Less education and more tornado experience was generally related to greater likelihood of experiencing probable PTSD and current depression for both surveys. Men and younger participants were more likely to report current depression at Survey 1. Low levels of social support (assessed only at Survey 2) were related to more probable PTSD and current depression. For both surveys, we observed low rates of mental health service utilization, and these rates were also low for participants reporting probable PTSD and current depression. At Survey 2 we assessed parent report of child (ages 4 to 17) strengths and difficulties and found that child difficulties were more frequent for younger children (ages 4 to 10) than older children (ages 11 to 17), and that parents reporting probable PTSD reported a greater frequency of children with borderline or abnormal difficulties. Discussion. Overall our results indicate that long-term (multi-year) community disaster mental health monitoring, assessment, referral, outreach, and services are needed following a major

For Survey 2 we also assessed social support and parent report of child strengths and difficulties. Results. Probable PTSD relevance was 12.63% at Survey 1 and 26.74% at Survey 2, while current depression prevalence was 20.82% at Survey 1 and 13.33% at Survey 2. Less education and more tornado experience was generally related to greater likelihood of experiencing probable PTSD and current depression for both surveys. Men and younger participants were more likely to report current depression at Survey 1. Low levels of social support (assessed only at Survey 2) were related to more probable PTSD and current depression. For both surveys, we observed low rates of mental health service utilization, and these rates were also low for participants reporting probable PTSD and current depression. At Survey 2 we assessed parent report of child (ages 4 to 17) strengths and difficulties and found that child difficulties were more frequent for younger children (ages 4 to 10) than older children (ages 11 to 17), and that parents reporting probable PTSD reported a greater frequency of children with borderline or abnormal difficulties. Discussion. Overall our results indicate that long-term (multi-year) community disaster mental health monitoring, assessment, referral, outreach, and services are needed following a major

    The atmosphere revitalization equipment aboard the International Space Station (ISS) and future deep space exploration vehicles provides the vital functions of maintaining a habitable environment for the crew as well as protecting the hardware from fouling by suspended particulate matter. Providing these functions are challenging in pressurized spacecraft cabins because no outside air ventilation is possible and a larger particulate load is imposed on the filtration system due to lack of sedimentation in reduced gravity conditions. The ISS Environmental Control and Life Support (ECLS) system architecture in the U.S. Segment uses a distributed particulate filtration approach consisting of traditional High-Efficiency Particulate Adsorption (HEPA) filters deployed at multiple locations in each module. These filters are referred to as Bacteria Filter Elements (BFEs). As more experience has been gained with ISS operations, the BFE service life, which was initially one year, has been extended to two to five years, dependent on the location in the U.S. Segment. In previous work we developed a test facility and test protocol for leak testing the ISS BFEs. For this work, we present results of leak testing a sample set of returned BFEs with a service life of 2.5 years, along with particulate removal efficiency and pressure drop measurements. The results can potentially be utilized by the ISS Program to ascertain whether the present replacement interval can be maintained or extended to balance the on-ground filter inventory with extension of the lifetime of ISS to 2024. These results can also provide meaningful guidance for particulate filter designs under consideration for future deep space exploration missions.

    Condylar fractures in children are especially important because of the risk of a mandibular growth-center being affected in the condylar head, which can lead to growth retardation and facial asymmetry. The purpose of this article is to follow up the two and half year clinical and radiological evaluation of the conservative treatment of a 10 year-old patient, who had a unilateral green-stick type fracture. The patient presented with painful facial swelling localized over the left condylar region, limited mouth-opening and mandibular deviation to the left. Panoramic radiography and computed tomography confirmed the diagnosis of incomplete fracture on the left condyle with one side of the bone fractured and the other bent. Closed reduction was chosen to allow for initial fibrous union of the fracture segments and remodeling with a normal functional stimulus. A non-rigid mandibular splint was applied in order to remove the direct pressure on the fracture side of the mandible. Clinical and radiologic examination after 30 months revealed uneventful healing with reduction of the condylar head and remodeling of the condylar process following conservative treatment.

    Millions of Mexico, US and across the world children are overweight and obese. Exposure to fossil-fuel combustion sources increases the risk for obesity and diabetes, while long-term exposure to fine particulate matter (PM2.5) and ozone (O3) above US EPA standards is associated with increased risk of Alzheimer's disease (AD). Mexico City Metropolitan Area children are chronically exposed to PM2.5 and O3 concentrations above the standards and exhibit systemic, brain and intrathecal inflammation, cognitive deficits, and Alzheimer disease neuropathology. We investigated adipokines, food reward hormones, endothelial dysfunction, vitamin D and apolipoprotein E (APOE) relationships in 80 healthy, normal weight 11.1±3.2 year olds matched by age, gender, BMI and SES, low (n: 26) versus high (n:54) PM2.5 exposures. Mexico City children had higher leptin and endothelin-1 (p<0.01 and p<0.000), and decreases in glucagon-like peptide-1 (GLP 1), ghrelin, and glucagon (<0.02) versus controls. BMI and leptin relationships were significantly different in low versus high PM2.5 exposed children. Mexico City APOE 4 versus 3 children had higher glucose (p=0.009). Serum 25-hydroxyvitamin D<30 ng/mL was documented in 87% of Mexico City children. Leptin is strongly positively associated to PM 2.5 cumulative exposures. Residing in a high PM2.5 and O3 environment is associated with 12h fasting hyperleptinemia, altered appetite-regulating peptides, vitamin D deficiency, and increases in ET-1 in clinically healthy children. These changes could signal the future trajectory of urban children towards the development of insulin resistance, obesity, type II diabetes, premature cardiovascular disease, addiction-like behavior, cognitive impairment and Alzheimer's disease. Increased efforts should be made to decrease pediatric PM2.5 exposures, to deliver health interventions prior to the development of obesity and to identify and mitigate environmental factors influencing obesity and Alzheimer

    The time variability and long term trends of PM2.5 (particulate matter of diameter < 2.5 μm) at various regional background (RB) sites across Europe are studied and interpreted in this work. Data on mean annual levels of PM2.5 measured at Montseny (MSY, North East Spain) and various RB sites in Spain and Europe are evaluated and compared, and subsequently analysed for statistically significant trends. The MSY site registered higher average PM2.5 levels than those measured at a selection of other RB sites across Spain, Portugal, Germany and Scandinavia by percentage compared to the mean of all the stations in these countries, but lower than those measured in Switzerland, Italy and Austria. Reductions in PM2.5 were observed across all stations in Spain and Europe to varying degrees (7-49%). MSY underwent a statistically significant reduction since measurements began, indicating a year-on-year gradual decrease (-3.7 μg m-3, calculated from the final year of data compared to the mean). Similar trends were observed in other RB sites across Spain (-1.9 μg m-3). Reductions recorded in PM2.5 across Europe were varied, with many experiencing gradual, year-on-year decreases (-1.8 μg m-3). These reductions have been attributed to various causes: the introduction and implementation of pollution abatement strategies in EU member states, the effect of the current economic crisis on emissions of PM2.5 and the influence of meteorology observed during the winters of 2009 and 2010. In addition, the North Atlantic Oscillation (NAO), a large scale meteorological phenomenon most prevalent during winter, was observed to influence the frequency of Saharan dust intrusions across the Iberian Peninsula. Chemical composition of PM2.5 at MSY is characterised by high levels of organic matter (OM) and sulphate, followed by crustal material, nitrate and ammonia. Sea Spray and elemental carbon (EC) comprised a minor part of the total PM2.5 mass. Statistical trend analysis was performed on the

    Background: Epidemiological studies have demonstrated associations between short-term exposure to PM2.5 and hospital admissions. The chemical composition of particles varies across locations and time periods. Identifying the most harmful constituents and sources is an important health and regulatory concern. Objectives: We examined pollutant sources for associations with risk of hospital admissions for cardiovascular and respiratory causes. Methods: We obtained PM2.5 filter samples for four counties in Connecticut and Massachusetts and analyzed them for PM2.5 elements. Source apportionment was used to estimate daily PM2.5 contributions from sources (traffic, road dust, oil combustion, and sea salt as well as a regional source representing coal combustion and other sources). Associations between daily PM2.5 constituents and sources and risk of cardiovascular and respiratory hospitalizations for the Medicare population (> 333,000 persons ≥ 65 years of age) were estimated with time-series analyses (August 2000–February 2004). Results: PM2.5 total mass and PM2.5 road dust contribution were associated with cardiovascular hospitalizations, as were the PM2.5 constituents calcium, black carbon, vanadium, and zinc. For respiratory hospitalizations, associations were observed with PM2.5 road dust, and sea salt as well as aluminum, calcium, chlorine, black carbon, nickel, silicon, titanium, and vanadium. Effect estimates were generally robust to adjustment by co-pollutants of other constituents. An interquartile range increase in same-day PM2.5 road dust (1.71 μg/m3) was associated with a 2.11% (95% CI: 1.09, 3.15%) and 3.47% (95% CI: 2.03, 4.94%) increase in cardiovascular and respiratory admissions, respectively. Conclusions: Our results suggest some particle sources and constituents are more harmful than others and that in this Connecticut/Massachusetts region the most harmful particles include black carbon, calcium, and road dust PM2.5.

    Adapalene 0.1%/benzoyl peroxide 2.5% gel (Epiduo™, Tactuo™) is the only fixed-dose combination product available that combines a topical retinoid with benzoyl peroxide; it targets three of the four main pathophysiologic factors in acne. This article reviews the therapeutic efficacy and tolerability of topical adapalene 0.1%/benzoyl peroxide 2.5% gel in the treatment of patients aged ≥ 12 years with acne vulgaris, as well as summarizing its pharmacologic properties. In three 12-week trials in patients aged ≥ 12 years with moderate acne, success rates were significantly higher with adapalene 0.1%/benzoyl peroxide 2.5% gel than with adapalene 0.1% gel or benzoyl peroxide 2.5% gel alone, and combination therapy had an earlier onset of action. In addition, significantly greater reductions in total, inflammatory, and noninflammatory lesion counts were seen in patients receiving adapalene 0.1%/benzoyl peroxide 2.5% gel than in those receiving adapalene 0.1% gel or benzoyl peroxide 2.5% gel alone. Adapalene 0.1%/benzoyl peroxide 2.5% gel did not significantly differ from clindamycin 1%/benzoyl peroxide 5% gel in terms of the reduction in the inflammatory, noninflammatory, or total lesion counts in patients with mild to moderate acne, according to the results of a 12-week trial. Twelve-week studies showed that topical adapalene 0.1%/benzoyl peroxide 2.5% gel in combination with oral lymecycline was more effective than oral lymecycline alone in patients with moderate to severe acne, and topical adapalene 0.1%/benzoyl peroxide 2.5% gel in combination with oral doxycycline hyclate was more effective than oral doxycycline hyclate alone in patients with severe acne. In patients with severe acne who responded to 12 weeks' therapy with topical adapalene 0.1%/benzoyl peroxide 2.5% gel plus oral doxycycline hyclate or oral doxycycline hyclate alone, an additional 6 months' therapy with adapalene 0.1%/benzoyl peroxide 2.5% gel was more effective than vehicle gel at

    The time variability and long term trends of PM2.5 (particulate matter of diameter <2.5 μm) at various regional background (RB) sites across Europe are studied and interpreted in this work. Long-term trends of PM2.5 concentrations are relatively scarce across Europe, with few studies outlining the changes measured in PM2.5 concentrations over a significant period of time. To this end, data on mean annual levels of PM2.5 measured at Montseny (MSY, North East Spain) and various RB sites in Spain and Europe are evaluated and compared, and subsequently analysed for statistically significant trends. The MSY site registered higher average PM2.5 levels than those measured at a selection of other RB sites across Spain, Portugal, Germany and Scandinavia, but lower than those measured in Switzerland, Italy and Austria.

    Holoprosencephaly results from the incomplete development of midline structures within the cerebrum and encompasses a series of abnormalities of mid-facial development. Here, we report a case of male holoprosencephaly associated with false median cleft of upper lip. This patient belonged clinically to the DeMyer's group IV holoprosencephaly, semilobar type. An infant with this type of holoprosencephaly has been thought to die generally within 1 to 2 years after birth and to rarely benefit from an operation. In this case, the patient had cheiloplasty at the age of 2.5 years at the request of his parents and he lives currently, being 3 years and 2 months old.

    The IMPROVE (Interagency Monitoring of PROtected Visual Environments) network monitors aerosol concentrations at 170 remote sites throughout the United States. Twenty-four-hour filter samples of particulate matter are collected every third day and analyzed for chemical composition. About 30 of the sites have operated continuously since 1988, and the sustained data record (http://views.cira.colostate.edu/web/) offers a unique window on regional aerosol trends. All elemental analyses have been performed by Crocker Nuclear Laboratory at the University of California in Davis, and sample filters collected since 1995 are archived on campus. The suite of reported elements has remained constant, but the analytical methods employed for their determination have evolved. For example, the elements Na - Mn were determined by PIXE until November 2001, then by XRF analysis in a He-flushed atmosphere through 2004, and by XRF analysis in vacuum since January 2005. In addition to these fundamental changes, incompletely-documented operational factors such as detector performance and calibration details have introduced variations in the measurements. Because the past analytical methods were non-destructive, the archived filters can be re-analyzed with the current analytical systems and protocols. The 15-year sample archives from Great Smoky Mountains (GRSM), Mount Rainier (MORA), and Point Reyes National Parks (PORE) were selected for reanalysis. The agreement between the new analyses and original determinations varies with element and analytical era. The graph below compares the trend estimates for all the elements measured by IMPROVE based on the original and repeat analyses; the elements identified in color are measured above the detection limit more than 90% of the time. The trend estimates are sensitive to the treatment of non-detect data. The original and reanalysis trends are indistinguishable (have overlapping confidence intervals) for most of the well-detected elements.

    This study was to investigate the levels of heavy metals in PM2.5 and in blood, the prevalence of respiratory symptoms and asthma, and the related factors to them. Lead and cadmium in both PM2.5 and blood were significant higher in Guiyu (exposed area) than Haojiang (reference area) (p < 0.05), however, no significant difference was found for chromium and manganese in PM2.5 and in blood. The prevalence of cough, phlegm, dyspnea, and wheeze of children was higher in Guiyu compared to Haojiang (p < 0.05). No significant difference was found for the prevalence of asthma in children between Guiyu and Haojiang. Living in Guiyu was positively associated with blood lead (B = 0.196, p < 0.001), blood cadmium (B = 0.148, p < 0.05) and cough (OR, 2.37; 95% CI, 1.30-4.32; p < 0.01). Blood lead>5 μg/dL was significantly associated with asthma (OR, 9.50; 95% CI, 1.16-77.49). Higher blood chromium and blood manganese were associated with more cough and wheeze, respectively. Our data suggest that living in e-waste exposed area may lead to increased levels of heavy metals, and accelerated prevalence of respiratory symptoms and asthma.

    Studies describing the chemical composition of fine aerosol (PM2.5) in urban areas are often conducted during few weeks only, and at one sole site, giving thus a narrow view of their temporal and spatial characteristics. This paper presents a one-year (11 September 2009-10 September 2010) survey of the daily chemical composition of PM2.5 in the region of Paris, which is the second most populated "Larger Urban Zone" in Europe. Five sampling sites representative of suburban (SUB), urban (URB), northeast (NER), northwest (NWR) and south (SOR) rural backgrounds were implemented. The major chemical components of PM2.5 were determined including elemental carbon (EC), organic carbon (OC), and the major ions. OC was converted to organic matter (OM) using the chemical mass closure methodology, which leads to conversion factors of 1.95 for the SUB and URB sites, and 2.05 for the three rural ones. On average, gravimetrically determined PM2.5 annual mass concentrations are 15.2, 14.8, 12.6, 11.7 and 10.8 μg m-3 for SUB, URB, NER, NWR and SOR sites, respectively. The chemical composition of fine aerosol is very homogeneous at the five sites and is composed of OM (38-47%), nitrate (17-22%), non-sea-salt sulfate (13-16%), ammonium (10-12%), EC (4-10%), mineral dust (2-5%) and sea salt (3-4%). This chemical composition is in agreement with those reported in the literature for most European environments. On the annual scale, Paris (URB and SUB sites) exhibits its highest PM2.5 concentrations during late autumn, winter and early spring (higher than 15 μg m-3 on average, from December to April), intermediates during late spring and early autumn (between 10 and 15 μg m-3 during May, June, September, October, and November) and the lowest during summer (below 10 μg m-3 during July and August). PM levels are mostly homogeneous at the regional scale, on the whole duration of the project (e.g. for URB plotted against NER sites: slope = 1.06, r2 = 0.84, n = 330), suggesting the

    This study aimed to determine the age of attainment of puberty, as well as the pattern of reproductive seasonality in males of Iberian red deer and the relationship of these factors with antler development. A second aim was to examine the effect of the advance of births on the variables mentioned. Fourteen males of Iberian deer were used, five of them born 2.5 months before the others (early group). Male deer were blood sampled from birth until 2.5 years of age to assess the time course of plasma testosterone. The study also included measurements of testicular and neck circumference. As in most cervids, concentration of plasma testosterone was associated to the phases of antler development. Early development affected testosterone titres, since the most precocious males in antler growth also showed higher levels of testosterone during the first and second year of age. In the same way, results suggested that the advance of calving may result in puberty attainment in the first autumn of its life. However, this would require an advance of calving greater than the one we induced since puberty in the Iberian deer is usually attained during second autumn of life at 15-16 months of age. Finally, calving advance also affected antler development. Thus, two of the five males whose birth was advanced, showed two antler cycles in their first year of life.

    The Supersito Project (http://www.supersito-er.it) has been active in the Emilia-Romagna region, southern part of the Po Valley (Italy), since 2011. Focal aim of the project is to enhance the knowledge on atmospheric aerosol and its impact on human health. In the framework of Supersito, major chemical components of daily PM2.5 were investigated over a period of more than three years at four sampling sites, representative of dissimilar territorial conditions: one rural background (SPC) and three urban background sites in the coastal (RN), central (MS) and inner area (PR) of the region. In all the sites, organic and elemental carbon and water soluble inorganic ions accounted for more than 70% of PM2.5 mass, during all seasons. Nitrate and organic carbon (OC) were the main components of winter PM2.5, while summer aerosol was mainly contributed by OC and sulphate. OC was dominated by primary sources, with a potentially important contribution from biomass burning, in winter, while secondary processes dominated OC production in summer. A substantial homogeneity was observed on a regional scale in terms of spatial distribution of pollutants, with EC only presenting significant differences between urban and rural areas during winters. Nonetheless, differences were observed between the coastal and the inner part of the region, with the former being systematically characterized by higher concentrations of carbonaceous compounds and lower concentrations of ammonium nitrate. The coastal area was likely influenced by the aged OC from the Po Valley outflow in addition to local sources, while the scarcity of local sources of ammonia limited the formation of ammonium nitrate. In the studied area, local and regional meteorology - mostly governed by geographical collocation and orography - was responsible for PM2.5 mass and composition no less than local and regional emission sources.

    Children's air pollution exposures are associated with systemic and brain inflammation and the early hallmarks of Alzheimer's disease (AD). The Apolipoprotein E (APOE) 4 allele is the most prevalent genetic risk for AD, with higher risk for women. We assessed whether gender, BMI, APOE and metabolic variables in healthy children with high exposures to ozone and fine particulate matter (PM2.5) influence cognition. The Wechsler Intelligence Scale for Children (WISC-R) was administered to 105 Mexico City children (12.32±5.4 years, 69 APOE 3/3 and 36 APOE 3/4). APOE 4v 3 children showed decrements on attention and short-term memory subscales, and below-average scores in Verbal, Performance and Full Scale IQ. APOE 4 females had higher BMI and females with normal BMI between 75-94% percentiles had the highest deficits in Total IQ, Performance IQ, Digit Span, Picture Arrangement, Block Design and Object Assembly. Fasting glucose was significantly higher in APOE 4 children p=0.006, while Gender was the main variable accounting for the difference in insulin, HOMA-IR and leptin (p<.05). Gender, BMI and APOE influence children's cognitive responses to air pollution and glucose is likely a key player. APOE 4 heterozygous females with >75% to <94% BMI percentiles are at the highest risk of severe cognitive deficits (1.5-2SD from average IQ). Young female results highlight the urgent need for gender-targeted health programmes to improve cognitive responses. Multidisciplinary intervention strategies could provide paths for prevention or amelioration of female air pollution targeted cognitive deficits and possible long-term AD progression.

    Until recently, it was generally assumed that the ability to attribute false beliefs did not emerge until about 4 years of age. However, recent reports using spontaneous- as opposed to elicited-response tasks have suggested that this ability may be present much earlier. To date, researchers have employed two kinds of spontaneous-response false-belief tasks: violation-of-expectation tasks have been used with infants in the second year of life, and anticipatory-looking tasks have been used with toddlers in the third year of life. In the present research, 2.5-year-old toddlers were tested in violation-of-expectation tasks involving a change-of-location situation (Experiment 1) and an unexpected-contents situation (Experiment 2). Results were positive in both situations, providing the first demonstrations of false-belief understanding in toddlers using violation-of-expectation tasks and, as such, pointing to a consistent and continuous picture of early false-belief understanding.

    A Web-based survey of adults who experienced loss during the September 11, 2001, terrorist attacks was conducted to examine the prevalence and correlates of complicated grief (CG) 2.5-3.5 years after the attacks. Forty-three percent of a study group of 704 bereaved adults across the United States screened positive for CG. In multivariate analyses, CG was associated with female gender, loss of a child, death of deceased at the World Trade Center, and live exposure to coverage of the attacks on television. Posttraumatic stress disorder, major depression, anxiety, suicidal ideation, and increase in post-9/11 smoking were common among participants with CG. A majority of the participants with CG reported receiving grief counseling and psychiatric medication after 9/11. Clinical and policy implications are discussed.

    Housing stability is an important focus in research on homeless people. Although definitions of stable housing differ across studies, the perspective of homeless people themselves is generally not included. Therefore, this study explored the inclusion of satisfaction with the participant's current housing status as part of the definition of housing stability and also examined predictors of housing stability with and without the inclusion of homeless person's perspective. Of the initial cohort consisting of 513 homeless participants who were included at baseline in 2011, 324 (63.2%) were also interviewed at 2.5-year follow-up. To determine independent predictors of housing stability, we fitted multivariate logistic regression models using stepwise backward regression. At 2.5-year follow-up, 222 participants (68.5%) were stably housed and 163 participants (51.1%) were stably housed and satisfied with their housing status. Having been arrested (OR = 0.36, 95% CI: 0.20-0.63), a high level of somatisation (physical manifestations of psychological distress) (OR = 0.52, 95% CI: 0.30-0.91) and having unmet care needs (OR = 0.77, 95% CI: 0.60-0.99) were negative predictors of housing stability. Having been arrested (OR = 0.43, 95% CI: 0.25-0.75), high debts (OR = 0.45, 95% CI: 0.24-0.84) and a high level of somatisation (OR = 0.49, 95% CI: 0.28-0.84) were negative predictors of stable housing when satisfaction with the housing status was included. Because inclusion of a subjective component revealed a subgroup of stably housed but not satisfied participants and changed the significant predictors, this seems a relevant addition to the customary definition of housing stability. Participants with characteristics negatively associated with housing stability should receive more extensive and individually tailored support services to facilitate achievement of housing stability.

  12. A New Hybrid Spatio-temporal Model for Estimating Daily Multi-year PM2.5 Concentrations Across Northeastern USA Using High Resolution Aerosol Optical Depth Data

    The use of satellite-based aerosol optical depth (AOD) to estimate fine particulate matter PM(sub 2.5) for epidemiology studies has increased substantially over the past few years. These recent studies often report moderate predictive power, which can generate downward bias in effect estimates. In addition, AOD measurements have only moderate spatial resolution, and have substantial missing data. We make use of recent advances in MODIS satellite data processing algorithms (Multi-Angle Implementation of Atmospheric Correction (MAIAC), which allow us to use 1 km (versus currently available 10 km) resolution AOD data.We developed and cross validated models to predict daily PM(sub 2.5) at a 1X 1 km resolution across the northeastern USA (New England, New York and New Jersey) for the years 2003-2011, allowing us to better differentiate daily and long term exposure between urban, suburban, and rural areas. Additionally, we developed an approach that allows us to generate daily high-resolution 200 m localized predictions representing deviations from the area 1 X 1 km grid predictions. We used mixed models regressing PM(sub 2.5) measurements against day-specific random intercepts, and fixed and random AOD and temperature slopes. We then use generalized additive mixed models with spatial smoothing to generate grid cell predictions when AOD was missing. Finally, to get 200 m localized predictions, we regressed the residuals from the final model for each monitor against the local spatial and temporal variables at each monitoring site. Our model performance was excellent (mean out-of-sample R(sup 2) = 0.88). The spatial and temporal components of the out-of-sample results also presented very good fits to the withheld data (R(sup 2) = 0.87, R(sup)2 = 0.87). In addition, our results revealed very little bias in the predicted concentrations (Slope of predictions versus withheld observations = 0.99). Our daily model results show high predictive accuracy at high spatial resolutions

    2017-01-01

    To analyze the characteristics of regional background carbonaceous aerosols in western Yangtze River Delta (YRD), hourly organic carbon (OC) and elemental carbon (EC) in fine particular matter (PM2.5) were measured with a semi-continuous carbon analyzer at a suburban site in upwind Nanjing from June 2013 to May 2015. Relatively low OC, EC and OC/EC were observed compared to other studies conducted in Nanjing. The reasons include the limited primary emissions around the observation site, the improved emission controls in recent years, and the use of denuder to reduce positive artifact in OC measurement. Resulting from the stable atmosphere conditions and emission variations, the highest concentrations of carbonaceous aerosols were found in both winters, with average OC and EC observed at 11.8 ± 10.0 and 5.9 ± 3.4 μg/m3 for the first one, and 8.1 ± 5 and 4.5 ± 2.4 μg/m3 for the second one, respectively. Compared to 2013, reduced OC and EC were found in summer and autumn 2014, demonstrating the benefits of emission control polices implemented for the Nanjing Youth Olympic, while elevated OC observed in spring 2015 was attributed probably to the increased biomass burning. For the hazy event in winter 2013, the back trajectories of air masses suggested that heavy pollution were from eastern Jiangsu, northern Anhui and Jiangsu, downtown Nanjing, and Shanghai. Secondary aerosol formation played an important role indicated by the larger mass fraction of OC and increased OC/EC in PM2.5 during the heavy pollution period. In the harvest season, biomass burning was estimated to contribute 51% and 16% of OC and EC concentrations, respectively.

    This study presents the first long term (10-year period, 2004–2013) datasets of PM2.5-bound nickel (Ni) concentration obtained from the daily sample in urban of Xi’an, Northwestern China. The Ni concentration trend, pollution sources, and the potential health risks associated to Ni were investigated. The Ni concentrations increased from 2004 to 2008, but then decreased due to coal consumption reduction, energy structure reconstruction, tighter emission rules and the improvement of the industrial and motor vehicle waste control techniques. With the comparison of distributions between workday and non-workday periods, the effectiveness of local and regional air pollution control policies and contributions of hypothetical Ni sources (industrial and automobile exhausts) were evaluated, demonstrating the health benefits to the populations during the ten years. Mean Ni cancer risk was higher than the threshold value of 10−6, suggesting that carcinogenic Ni still was a concern to the residents. Our findings conclude that there are still needs to establish more strict strategies and guidelines for atmospheric Ni in our living area, assisting to balance the relationship between economic growth and environmental conservation in China.

    A descriptive cross sectional study was done in the department of Pediatrics Mymensingh Medical College Hospital. The purpose of the study was to assess breast feeding pattern, complementary feeding pattern, types of complementary foods and also to assess the nutritional status and to detect any relationship with the nutritional status and the feeding practices. Mothers with their children aged less than 2 years were included and very sick children, mother less children, handicapped children were excluded. Four hundred (400) consecutive children were enrolled from eight upazillas of Mymensingh district who were selected randomly. Out of 400 children, 214 children (53.5%) were male and 186 children (47.5%) were female and M:F was 1.2:1. Exclusive breastfeeding rate was 41.5%. Pre-lacteal feeding rate were 30.7% and most common pre-lacteal foods were honey and sugar water. Colostrum was given in 69.3% children. Breast feeding continued at the time of interview was 58.1%. Complementary feeding started in time in 35.8%, early weaning in 44.5% children. Type of complementary food was mainly luta (rice powder mixed with boiled water and sugar only) in 38.8% and khichuri (rice, pulses, soybean oil) in 19.5%. Bottle feeding rate was 31.30%. Around 43% children were underweight and 10.25% children were severely underweight and common in between 12 to 23 months of age group. Around 29% children were stunted among 11.25% were severely stunted. About 13.5% children were wasted and among them 2.5% were severely wasted. Stunting prevalent over the age of 9 months and wasting started after 6 months of age. Malnutrition was common in partially breast fed and early weaning with carbohydrate rich food.

    The home remains a very common location for deadly injuries among children younger than 5 years. The aim of this study is to describe the demographic and injury characteristics of domestic injuries in children younger than 5 years. The National Trauma Data Bank's National Sample Program data set was queried for children younger than 5 years with the injury site classified as home. Bivariate analysis was performed to determine unadjusted differences by ethnicity. Appropriate weight was applied to the sample to determine accurate national estimates. A total of 7,364 children, representing 32,033 children, were analyzed. Overall mortality was 1.6 per cent. Among whites, blacks, Hispanics, Asians, and Native Americans, intentional injuries accounted for 6.5, 12.8, 10.2, 5.2, and 19.0 per cent of all injuries by intent, respectively (P < 0.003). Burn injury was disproportionately higher in blacks (24.1%) followed by Native Americans and Asians (15.3 and 11.5%, P = 0.008). On multivariate analysis, black ethnicity was associated with increased length of stay. Intentional injuries were significantly higher in blacks and Native Americans with black patients sustaining a disproportionately higher proportion of burn injury. Therefore, greater attention is needed to provide more effective home safety interventions to children among high-risk ethnic groups.

  15. Acquired myopia in 11-year-old children.

    Peckham, C S; Gardiner, P A; Goldstein, H

    1977-02-26

    Children who had acquired myopia by the age of 11 years were identified from a nationally representative sample. There were no overall sex differences in its occurrence but myopia was more common in children from non-manual families than in those from manual families. Short-sighted children were more likely to come from small families and to be of higher birth order than children with normal vision, and these associations held within each social class. At 11 years myopic children showed striking advantages in educational performance over their normal-sighted peers, as judged by tests of reading, arithmetic, and general ability. After adjustments had been made for social background, this age gain still amounted to over one year. Findings obtained at 7 years of age showed that superior educational attainments were already apparent before the onset of myopia. Children with myopia read in their leisure time more often than normally sighted children, but despite the visual impairment, they participated in outdoor sports as often as other children.

    Background Children with intellectual or developmental disabilities (ID/DD) are more likely than typically developing children to experience behaviour problems. Parent training, such as the Incredible Years Parent Training (IYPT) series, has been a widely used intervention to support families with children with or at-risk for behaviour problems; yet to date, this programme has not been used with parents with young children with developmental delay or disabilities. Method This preliminary treatment group only study assessed the feasibility of implementing a modified parent training programme (IYPT-DD) with 25 families with 2-5 year old children with developmental delay. Intervention consisted of 12 weekly (2 ½ hour) sessions with topics covering developmentally appropriate play, praise, rewards, limit setting, and handling challenging behaviour. Results Results suggest preliminary evidence of efficacy in reducing negative parent and child behaviour and increasing parental perceptions of child positive impact. Conclusions This study provides evidence for the feasibility of the DD modifications applied to the IYPT. Although this approach is promising, additional evidence is needed to address the efficacy of IYPT-DD in children with developmental delay. PMID:18671808

    Background: Minimally invasive surgery is the current approach to perform heminephroureterectomy (HN) in children. This can be obtained through a transperitoneal (TP) or a retroperitoneal approach. Here, we report our experience using a TP approach. Materials and Methods: From 2005 to 2014, 22 TP laparoscopic upper poles HN were performed at our institution. There were nine girls and 13 boys aged between 20 months and 6 years (mean age 3.9). Eight patients were diagnosed prenatally, 17 patients presented with urinary tract infection (UTI) and three with vomiting and failure to thrive. The indication for HN was reflux nephropathy and UTI in non-functioning upper pole in 19 patients and cystic dysplasia in 1 patient. The surgical technique involved the following steps: Cystoscopic recognition; positioning of 3-4 trocar (right HN); identification of the kidney (detachment of the colon); isolation and low ligation of the dilated ureter; decrossing from renal vessels; section of the parenchyma by LigaSure; haemostasis with clips and LigaSure; drain. Results: The mean operative time was 154 min (range: 81-220 min). All patients were discharged from the 2nd to 4th day. Neither major complication nor conversion was recorded. 1 patient presented leakage of urine for 7 days from the drainage which resolved spontaneously. At ultrasound follow-up, 5 patients showed a secondary perirenal cyst, 2-5 cm diameter that resolved spontaneously. Conclusion: The results indicate that laparoscopic upper pole heminephrectomy is the treatment of choice in cases of non-functioning dilated lower segments of duplicated kidneys. The use of laparoscopic approach offers a good working space, a good visual control of the vessels and allows a very low isolation of the ureteral stump which counterbalance the peritoneal violation.

    2,5-Dimethylfuran, 2-methylfuran, and C9—C20n-alkanes have been isolated from the kerogen of a Rupemba stromatolite. These furans could be the oldest known stable remnants of biological carbohydrates if it is possible to prove that their progenitors are as old as the rock. Experiments showed that it is improbable that these compounds are analytical artifacts or laboratory contaminations. Postdepositional contaminations caused by fluids flowing through the rocks seem doubtful because of minimal permeability, which is supported by petrographic observations. Contamination by diffusion also appears to be unlikely. Because the rock had a mild temperature history, these molecules could have survived since Archean time. Because of all the evidence, the furans and alkanes are quite likely biochemical fossils. PMID:16592603

    19 young children (less than 5 years old) have received 31 renal transplants from 4 live relatives and 27 cadaver donors. The 2-year allograft survival rate for the patients receiving their 1st allograft from the 4 live donors was 75 +/- 22% while for the patients receiving their 1st allograft from 15 cadaver donors was 26 +/- 11%. 10 children are currently surviving with functioning allographs (7 cadavers and 3 live relatives); 4 have died and 5 are undergoing dialysis after the loss of at least one allograft. Despite the poor allograft survival rate the fact that 7 children are surviving with cadaver allografts indicates that the lack of a living related donor should not prevent transplants in young children.

    Rotational ambiguity in factor analyses leads to solutions that are not always consistent with reality. The inherent non-negativity constraints in positive matrix factorization (PMF) help to prevent factor solutions from becoming overly unrealistic, but they are not sufficient to prevent unwanted rotations that could manifest in factors that should have similar compositions varying across multiple sites. The Canadian National Air Pollution Surveillance (NAPS) network operates five fine particulate matter (PM2.5) speciation sites in Ontario. Data from these sites from 2005 to 2010 were subjected to PMF to obtain factors representing sources of particulate matter. Eight factors were found to be common across these sites. These factors had profiles that varied greatly from one site to the other, suggesting that the PMF solutions were impacted by some rotational ambiguity. New features in the EPA PMF V5 program allow the use of a priori information to impose mathematical constraints that guide the evolution of the factor solutions. These constraints reduce the rotational space. In situations where major emissions sources are known and located in the neighborhood of receptors, or emissions inventories and literature source profiles exist, it is easy to use these profiles to force the factor solutions to conform to the expected signatures. In our case, reported source profiles were neither available nor applicable due to the large spatial span of potential sources and receptor sites. This work describes how such constraints can be generated and used in these complex situations. The fundamental principle explored in this work is the concept of 'stiffness' of PMF solutions to identify the desirable non-rotating factors.

    The aim of this study was to analyze sexual behaviors and attitudes of children 9-14 years old in Spain. In this article we present data from 470 children of which 52% are boys and 48% girls. In order to evaluate the sample, Information, Attitudes and Behaviors related to Health Questionnaire (CIACS-II) was used. Results evidence that boys 9 years old already show behaviors that evidence their interest towards sexuality. 8% have sometimes masturbated and 9% have used pornography for becoming excited. 14% of children 11-12 years old have already had sexual relations and 38% state to have sexual fantasies. Girls start to masturbate and to have sexual relations later than boys and show a prevalence of sexual fantasies and use of pornography very lower. It is necessary sexual education programs to be implanted since early ages in schools.

    Background Few studies examining the associations between long-term exposure to ambient air pollution and mortality have considered multiple pollutants when assessing changes in exposure due to residential mobility during follow-up. Objective We investigated associations between cause-specific mortality and ambient concentrations of fine particulate matter (≤ 2.5 μm; PM2.5), ozone (O3), and nitrogen dioxide (NO2) in a national cohort of about 2.5 million Canadians. Methods We assigned estimates of annual concentrations of these pollutants to the residential postal codes of subjects for each year during 16 years of follow-up. Historical tax data allowed us to track subjects’ residential postal code annually. We estimated hazard ratios (HRs) for each pollutant separately and adjusted for the other pollutants. We also estimated the product of the three HRs as a measure of the cumulative association with mortality for several causes of death for an increment of the mean minus the 5th percentile of each pollutant: 5.0 μg/m3 for PM2.5, 9.5 ppb for O3, and 8.1 ppb for NO2. Results PM2.5, O3, and NO2 were associated with nonaccidental and cause-specific mortality in single-pollutant models. Exposure to PM2.5 alone was not sufficient to fully characterize the toxicity of the atmospheric mix or to fully explain the risk of mortality associated with exposure to ambient pollution. Assuming additive associations, the estimated HR for nonaccidental mortality corresponding to a change in exposure from the mean to the 5th percentile for all three pollutants together was 1.075 (95% CI: 1.067, 1.084). Accounting for residential mobility had only a limited impact on the association between mortality and PM2.5 and O3, but increased associations with NO2. Conclusions In this large, national-level cohort, we found positive associations between several common causes of death and exposure to PM2.5, O3, and NO2.

  7. Justification for Rhinoseptoplasty in Children – Our 10 Years Overview

    PubMed Central

    Kopacheva-Barsova, Gabriela; Nikolovski, Nikola

    2016-01-01

    BACKGROUND: Nasal septal surgery and rhinoplasty are controversial in children. Traditionally, an attitude of restraint has been employed by most surgeons till an empirical age of 16 to 18 years. This is to avoid the possible adverse effects that the growth spurts may have on the nose and midface region. AIM: The aim of this paper was to present the results of rhinoplasty in children in order to restore the anatomy and function or to promote normal development and outgrowth of the nose. MATERIAL AND METHODS: Ninety seven children aged 6-14, with severe nose deformities and breathing problems through the nose, were admitted for septo/rhinoplasty at the University Clinic for Ear, Nose and Throat, Faculty of Medicine, Ss Cyril and Methodius University of Skopje, Republic of Macedonia. At our Clinic, they have been observed and photographed (with parent permission) in the period of 10 years (2006-2016). The most frequent cause of these deformities was the nasal trauma in early childhood which was ignored or untreated. All of them rhino/septoplasty were indicated in accordance with the above-mentioned recommendations for rhino/septoplasty in early childhood and in adolescents. RESULTS: In 51 children and adolescents septoplasty were prepared. Mostly there was a group of younger children age from 6-10 (68%) and adolescents (32%). In the other 31 children and adolescents, septorhinoplasty was prepared. Mostly there were children older than 12 years old and adolescents (70%). Only 30% were younger than 12 years, of course with severe nasal breathing problems, nasal septal deformities and deformities of the nasal pyramid. CONCLUSION: The growth centres of the nose have to be avoided if possible; long-term nasal issues will theoretically be minimised. If the surgeon replaces it, the cartilage of the nose becomes straighter but still intact. PMID:27703562

    Context. To fully exploit the scientific potential of the Fermi mission for the physics of active galactic nuclei (AGN), we initiated the F-GAMMA programme. Between 2007 and 2015 the F-GAMMA was the prime provider of complementary multi-frequency monitoring in the radio regime. Aims: We quantify the radio variability of γ-ray blazars. We investigate its dependence on source class and examine whether the radio variability is related to the γ-ray loudness. Finally, we assess the validity of a putative correlation between the two bands. Methods: The F-GAMMA performed monthly monitoring of a sample of about 60 sources at up to twelve radio frequencies between 2.64 and 228.39 GHz. We perform a time series analysis on the first 2.5-yr data set to obtain variability parameters. A maximum likelihood analysis is used to assess the significance of a correlation between radio and γ-ray fluxes. Results: We present light curves and spectra (coherent within ten days) obtained with the Effelsberg 100 m and IRAM 30 m telescopes. All sources are variable across all frequency bands with amplitudes increasing with frequency up to rest frame frequencies of around 60-80 GHz as expected by shock-in-jet models. Compared to flat-spectrum radio quasars (FSRQs), BL Lacertae objects (BL Lacs) show systematically lower variability amplitudes, brightness temperatures, and Doppler factors at lower frequencies, while the difference vanishes towards higher ones. The time scales appear similar for the two classes. The distribution of spectral indices appears flatter or more inverted at higher frequencies for BL Lacs. Evolving synchrotron self-absorbed components can naturally account for the observed spectral variability. We find that the Fermi-detected sources show larger variability amplitudes, brightness temperatures, and Doppler factors than non-detected ones. Flux densities at 86.2 and 142.3 GHz correlate with 1 GeV fluxes at a significance level better than 3σ, implying that γ rays are

    Introduction & Objectives: High-Intensity Focused Ultrasound (HIFU) has been shown to be a successful treatment for localised prostate cancer (PC). Here we have explored the effectiveness of the HIFU treatment for hormone-resistant prostate cancer (HRPC). Materials & Methods: 341 patients were treated in our center between September 2007 and December 2009; all of them showed treatment failure following hormone ablation. The median time before hormone-resistance was 20 (3-48) months. In the group with localised PC: number of patients 237, Gleason score ≤7, stage T1-2N0M0, age 69 (60-89) years, mean PSA before treatment 40,0 (5,8-92,9) ng/ml, mean prostate volume—39,3 (28-92) cc; in the group with locally advanced PC: number of patients 104, Gleason score ≤9, stage T2-3N0M0, age 72 (52-83) years, PSA before treatment 30,3 (20,1-60) ng/ml, mean prostate volume—41,2 (25-198) cc. HIFU was delivered under spinal anesthesia using the Ablatherm HIFU device (EDAP, France). Pre HIFU transurethral resection of the prostate (TURP) was performed for all patients. Mean follow-up time 18 months (3-30). Results: The median PSA level 12 months after HIFU treatment was 0,04 (0-2,24) ng/ml—localised PC, and for locally advanced disease—0,05 (0-48,4) ng/ml, at 18 months after HIFU treatment this was 0,2 (0,02-2,0) ng/ml for localised PC, and for locally advanced disease 0,18 (0,04-7,45) ng/ml. Patients with localised PC has 4,5% recurrence, those with locally advanced PC 20%. Kaplan-Meir analyses of the total group indicated that the risk of recurrence after 1 year follow-up was 10%, the risk of recurrence was 19% after 2 years of follow-up. Conclusions: Our initial experience shows that ultrasound ablation is safe, minimally invasive and effective as a treatment for localised and locally advanced hormone-resistant prostate cancer.

  16. Multi-year objective analyses of warm season ground-level ozone and PM2.5 over North America using real-time observations and Canadian operational air quality models

    NASA Astrophysics Data System (ADS)

    Robichaud, A.; Ménard, R.

    2013-05-01

    We present multi-year objective analyses (OA) on a high spatio-temporal resolution (15 or 21 km, every hour) for the warm season period (1 May-31 October) for ground-level ozone (2002-2012) and for fine particulate matter (diameter less than 2.5 microns (PM2.5)) (2004-2012). The OA used here combines the Canadian Air Quality forecast suite with US and Canadian surface air quality monitoring sites. The analysis is based on an optimal interpolation with capabilities for adaptive error statistics for ozone and PM2.5 and an explicit bias correction scheme for the PM2.5 analyses. The estimation of error statistics has been computed using a modified version of the Hollingsworth-Lönnberg's (H-L) method. Various quality controls (gross error check, sudden jump test and background check) have been applied to the observations to remove outliers. An additional quality control is applied to check the consistency of the error statistics estimation model at each observing station and for each hour. The error statistics are further tuned "on the fly" using a χ2 (chi-square) diagnostic, a procedure which verifies significantly better than without tuning. Successful cross-validation experiments were performed with an OA set-up using 90% of observations to build the objective analysis and with the remainder left out as an independent set of data for verification purposes. Furthermore, comparisons with other external sources of information (global models and PM2.5 satellite surface derived measurements) show reasonable agreement. The multi-year analyses obtained provide relatively high precision with an absolute yearly averaged systematic error of less than 0.6 ppbv (parts per billion by volume) and 0.7 μg m-3 (micrograms per cubic meter) for ozone and PM2.5 respectively and a random error generally less than 9 ppbv for ozone and under 12 μg m-3 for PM2.5. In this paper, we focus on two applications: (1) presenting long term averages of objective analysis and analysis increments

    Between 1965 and 1980, 64 children form 1 to 19 years of age have undergone replacement of the aortic, mitral, or tricuspid valve at The Johns Hopkins Hospital. Three of these patients have had successful second valve replacements 4 to 12 years after the initial operation. During the first 5 year period of this review, the hospital mortality was 31%, whereas only one of 33 children having valve replacement during the most recent 5 year period died early after operation (hospital mortality, 1976 to 1980, 3%). Thromboembolic complications have been seen in only two patients in this group, for an incidence of 0.8% per patient-year. Among patients receiving long-term warfarin anticoagulation, there has been only one major bleeding episode in 133 patient-years of follow-up. The type of valve prosthesis implanted during this 15 year period has changed greatly. Ninety-four percent of the prostheses placed during the initial 5 year period were the caged-poppet type of valve, whereas tilting disc, central flow, and tissue valve substitutes have been implanted more recently. Eight of the 10 patients most recently undergoing valve replacement have received St. Jude Medical prostheses, and postoperative catheterization studies have confirmed the excellent hemodynamic performance of these valves, even in patients with prostheses of very small annular diameter. Despite the disappointing occurrence of premature tissue valve failure in the young population, valve replacement in children currently is safer and there is a wider variety of technically satisfactory valve substitutes available for implantation today.

    Atopic dermatitis (AD) is a common eczematous skin condition; as many as 10-17 percent of all children are affected, and 35-60 percent of affected patients manifest symptoms manifest during the first year of life. Treatment principles for AD in young children involve conservative measures such as avoidance of hot water and environmental irritants, combined with liberal use of emollients after bathing. Low potency topical corticosteroids (TCS) are the current standard of therapy for AD in young children, reserving mid- and high-potency TCS for severe disease. However, complications of long-term use of TCS include skin atrophy, stria formation, telangiectasia, hypopigmentation, secondary infections, steroid acne, allergic contact dermatitis, and miliaria. The pediatric population is also at increased risk for systemic absorption because of their high ratio of skin surface to body mass. Systemic absorption may result in hypothalamic-pituitary-adrenal axis suppression and ultimately growth retardation. Although most topical and systemic corticosteroids are not approved by the Food and Drug Administration for use in children less than 2 years of age, conservative treatment often fails in this age group and frequently patients are treated with TCS, antibiotics, and antihistamines.

  20. Wildland fire management and air quality in the southern Sierra Nevada: using the Lion Fire as a case study with a multi-year perspective on PM(2.5) impacts and fire policy.

    PubMed

    Schweizer, Don; Cisneros, Ricardo

    2014-11-01

    Management of fire is an important and controversial policy issue. Active fire suppression has led to a backlog of fuels, limited the ecological benefits of fire, and reduced short-term smoke impacts likely delaying these emissions to future generations over a larger spatial extent. Smoke impacts can be expected to increase as fire size and intensity increase and the fuel backlog is consumed; whether through reintroduction of fire under desirable conditions or through stand replacing fire. Land Management Agencies would like to increase the use of naturally ignited fires to burn during favorable conditions as a way to reduce catastrophic fires. This study provides information about the levels of air quality impacts expected from these types of fires and discusses some of the policy controversies of managed fire that propagate inconsistencies between agencies and enter the public discourse. The Lion Fire, a primarily low intensity 8,370 ha fire that was extensively monitored for Particulate Matter less than 2.5 microns (PM2.5), is used to quantify impacts to air quality. PM2.5 monitoring sites are used to assess exposure, public health impacts, and subsequently quantify annual air quality during a year with a fire that is within the historic normal fire size and intensity for this area. Ground level PM2.5 impacts were found to be localized with 99% of the hourly Air Quality Index readings in the moderate or good category for the sites impacted by the fire. PM2.5 concentrations at sites nearest the fire were below annual federal air quality standards for PM2.5 with annual 98th percentile at the most impacted sites (Johnsondale, Kernville, and Camp Nelson) of 35.0, 34.0, and 28.0 μg m(-3) respectively. Smoke impacts to PM2.5 concentrations were not found to reach the populated Central Valley. The findings suggest that this type of fire can be implemented with minimal public health impacts thus allowing an opportunity for air and fire managers to alter policy to

  1. Two and a half-year-old children are prosocial even when their partners are not.

    2013-10-01

    A total of 33 2.5-year-old toddlers were tested for proactive and selective prosocial responding in an iterated Prosocial Game with unfamiliar adult partners who were communicatively neutral and alternated their roles as actors and recipients every other trial. When children were actors, they were required to choose, at no cost to themselves, between a selfish option that delivered a reward to them only (1/0) and a prosocial option that delivered identical rewards to both themselves and their partners (1/1). When adult partners were actors, they consistently behaved prosocially (1/1) or selfishly (1/0) over 10 alternating trials, depending on test condition. An additional 17 children were used as a recipient-absent control group to test for self-oriented versus other-oriented prosocial preferences. This study shows that by 2.5 years of age, and in the particular context of the task administered, toddlers can display proactive, other-oriented prosocial behavior, but their prosocial responding is indiscriminate in that they fail to respond contingently to their partners' prosocial or selfish behavior in the previous trials. These findings lend further support to the view that human prosociality is in place early in development as a basic tendency to be nice to others. This inclination may be so strong that not even partners who are communicatively neutral or repeatedly selfish toward children can erode it. They also suggest that this precocious proactive prosociality may be independent of reciprocity in terms of both its developmental schedule and psychological scaffolding.

    2007-05-01

    Forty-eight children with an average age of 7.2 years (range: 3-12 years) were examined clinically and radiographically at an average 4-year follow-up (range: 2-10 years), between 1989 and 2000 to analyze correction of deformities following tibial shaft fractures. An inconsistent alteration in the length of the fractured tibia was observed. Anterior angular deformity realigned maximally (52.7%) followed by varus (40.9%) and valgus (23.9%) deformities. Posterior deformity corrected the least (18.5%). In the sagittal plane, acceptable critical anterior and posterior angular deformities that corrected completely were 12 degrees and 6 degrees respectively. In the coronal plane, acceptable critical angular deformities were 10 degrees varus and 8 degrees valgus.

    Leprosy is a chronic infectious disease caused by Mycobacterium leprae, representing a public health issue in some countries. Though more prevalent in adults, the detection of new cases in children under 15 years of age reveals an active circulation of bacillus, continued transmission and lack of disease control by the health system, as well as aiding in the monitoring of the endemic. Among patients under 15 years of age, the most affected age group is children between 10 and 14 years of age, although cases of patients of younger than 1 year of age have also been reported. Household contacts are the primary source of infection, given that caretakers, such as babysitters and others, must be considered in this scenario. Paucibacillary forms of the disease prevailed, especially borderline-tuberculoid leprosy, with a single lesion in exposed areas of the body representing the main clinical manifestation. Reactional states: Lepra reactions are rare, although some authors have reported high frequencies of this phenomenon, the most frequent of which is Type 1 Lepra Reaction. Peripheral nerve involvement has been described at alarming rates in some studies, which increases the chance of deformities, a serious problem, especially if one considers the age of these patients. The protective effect of BCG vaccination was found in some studies, but no consensus has been reached among different authors. Children must receive the same multidrug therapy regimen and the doses should, ideally, be calculated based on the child´s weight. Adverse reactions to this therapy are rare within this age group. This article aims to review epidemiological, clinical, and therapeutic aspects of leprosy in patients under 15 years of age. PMID:27192519

    We report the results of patch tests carried out over the last 6 years (1992 1997) on 141 children. This corresponds to 2.8% of the total patients who were patch tested in our Allergy Department (5,014). These 141 children were patch tested using the TRUE Test standard series and an additional allergen, metallic mercury. Allergens from the Chemotechnique medicaments, cosmetics, plants and shoe series were added in some. The most frequent localization of eczema was to the feet, face and hands and the most frequent suspected causes were costume jewelry, footwear, topical medicaments and cosmetics. The most frequent allergens, assessed by degree of relevance, were first, nickel, followed by cobalt, mercurials (thimerosal and metallic mercury), fragrance and rubber chemicals (naphthyl mix, mercapto mix, carba mix and PPD mix). 13 children, 18% of the total, between the ages of 12 and 14 years, showed positivities relevant to some occupation, i.e., metalworking, building, hairdressing, catering, etc. Once patch tests had been carried out and relevant positive patch tests assessed, the most frequent diagnoses were contact dermatitis 45%, atopic dermatitis 25%, juvenile plantar dermatitis 15%, and other diagnoses in the remaining 15%.

    The clinical and urodynamic approach to enuretic children over a period of more than 20 years has allowed the authors to develop a multifactorial pathophysiological concept of this disorder. The main factors involved are psychological, familial, genetic, vesical, due to bladder immaturity, hormonal, due to a defect of nocturnal ADH secretion, hygiene and dietary habits, etc. The sleep factor is predominant in the majority of cases. Although nocturnal enuresis is apparently isolated in many cases, it is often associated with a state of bladder immaturity, sometimes latent during the day, but occurring at night with episodes of detrusor hyperactivity, occurring during various phases of sleep. In practice, the recognition, in children, of these factors, some of which require specific treatments, implies a management combining several of these therapeutic modalities.

    Background and purpose Idiopathic clubfoot can be bilateral or unilateral; however, most studies of gait have assessed clubfoot cases as one uniform group. The contralateral foot in children with unilateral clubfoot has shown deviations in pedobarographic measurements, but it is seldom included in studies of gait. We evaluated gait in children with idiopathic clubfoot, concentrating on foot involvement. Patients and methods Three-dimensional gait analyses of 59 children, mean age 5.4 years, with bilateral (n = 30) or unilateral (n = 29) idiopathic clubfoot were stratified into groups of bilateral, unilateral, or contralateral feet. Age-matched controls (n = 28) were evaluated for comparison. Gait assessment included: (1) discrete kinematic and kinetic parameters, and (2) gait deviation index for kinematics (GDI) and kinetics (GDI-k). Results No differences in gait were found between bilateral and unilateral idiopathic clubfoot, but both groups deviated when compared to controls. Compared to control feet, contralateral feet showed no deviations in discrete gait parameters, but discrepancies were evident in relation to unilateral clubfoot, causing gait asymmetries in children with unilateral involvement. However, all groups deviated significantly from control feet according to GDI and GDI-k. Interpretation Bilateral and unilateral idiopathic clubfoot cases show the same persistent deviations in gait, mainly regarding reduced plantarflexion. Nevertheless, knowledge of foot involvement is important as children with unilateral clubfoot show gait asymmetries, which might give an impression of poorer deviations. The results of GDI/GDI-k indicate global gait adaptations of the contralateral foot, so the foot should preferably not be used as a reference for gait. PMID:27331243

    By conducting a case-control study in two university hospitals, we explored the association between modifiable risk behaviours and diarrhoea. Children aged <5 years attending outpatient clinics for diarrhoea were matched by age and sex with controls. Data were collected on family demographics, socioeconomic indicators, and risk behaviour practices. Two rectal swabs and a stool specimen were collected from cases and controls. Samples were cultured for bacterial pathogens using standard techniques and tested by ELISA to detect rotavirus and Cryptosporidium spp. Four hundred cases and controls were enrolled between 2007 and 2009. The strongest independent risk factors for diarrhoea were: presence of another household member with diarrhoea [matched odds ratio (mOR) 4.9, 95% CI 2.8-8.4] in the week preceding the survey, introduction to a new kind of food (mOR 3, 95% CI 1.7-5.4), and the child being cared for outside home (mOR 2.6, 95% CI 1.3-5.2). While these risk factors are not identifiable, in some age groups more easily modifiable risk factors were identified including: having no soap for handwashing (mOR 6.3, 95% CI 1.2-33.9) for children aged 7-12 months, and pacifier use (mOR 1.9, 95% CI 1.0-3.5) in children aged 0-6 months. In total, the findings of this study suggest that community-based interventions to improve practices related to sanitation and hygiene, handwashing and food could be utilized to reduce the burden of diarrhoea in Egyptian children aged <5 years.

    To describe bacteriologic epidemiology of bone and joint infections, a total of 52 osteomyelitis, 52 arthritis and 20 osteoarthritis of children aged one month to 15 years during a one-year period (2001) were included in a retrospective unicentric review. The mean age was 3,9 +/-3,6 years. Fever and pain were the most common clinical symptoms. The site of infection was single in 95%, involving lower extremities in 80%. Bone scintigraphy was abnormal in 71% of osteomyelitis. Positive cultures was obtained in 29% of all cases (blood cultures: 20%, aspiration cultures: 29%), but in 42% of cases which have both blood and aspiration cultures. Thirty-six bacteria were identified: 19 Staphylococcus (14 aureus), ten Streptococcus (four pneumoniae), three Salmonella, three Kingella kingae, one Moraxella. All the isolates were susceptible to the empiric antibiotic therapy. Outcome was good in 100% of osteomyelitis and in 96% of arthritis.

    In Argentina, there is no information on ages of attainment of developmental milestones and very few data about environmental factors that influence them. A national survey on the psychomotor development of children under 6 years of age was carried out with the help of 129 paediatricians. Logistic regression was applied to a final sample of 3573 healthy, normal children in order to estimate selected centiles (25th, 50th, 75th and 90th), together with their respective confidence intervals, of the ages of attainment of 78 developmental items belonging to the following areas: personal-social (18 items), fine motor (19), language (18) and gross motor (23). The 50th centile obtained for each of the 43 comparable items was compared with those obtained in previously standardised tests: DDST, Denver II, Bayley and Chilean scales. Neither significant nor systematic differences were found between our results and those described in the tests used for comparison. Multiple logistic regressions showed that social class, maternal education and sex (female) were associated with earlier attainment of some selected developmental items, achieved at ages later than 1 year. Selected items achieved before the first year of life were not affected by any of the independent environmental variables studied. The information is useful in helping paediatricians in their daily practice for surveillance of development, as baseline information for epidemiological studies on development in our country and for cross-cultural analysis.

  12. Spontaneous analog number representations in 3-year-old children.

    2010-03-01

    When enumerating small sets of elements nonverbally, human infants often show a set-size limitation whereby they are unable to represent sets larger than three elements. This finding has been interpreted as evidence that infants spontaneously represent small numbers with an object-file system instead of an analog magnitude system (Feigenson, Dehaene & Spelke, 2004). In contrast, non-human animals and adult humans have been shown to rely on analog magnitudes for representing both small and large numbers (Brannon & Terrace, 1998; Cantlon & Brannon, 2007; Cordes, Gelman, Gallistel & Whalen, 2001). Here we demonstrate that, like adults and non-human animals, children as young as 3 years of age spontaneously employ analog magnitude representations to enumerate both small and large sets. Moreover, we show that children spontaneously attend to numerical value in lieu of cumulative surface area. These findings provide evidence of young children's greater sensitivity to number relative to other quantities and demonstrate continuity in the process they spontaneously recruit to judge small and large values.

    Diarrhoea is one of leading causes of morbidity and mortality worldwide. Recent estimations suggested the number of deaths is close to 2.5 million. This study examined the causative agents of diarrhoea in children under 5 years of age in suburban areas of Khartoum, Sudan. A total of 437 stool samples obtained from children with diarrhoea were examined by culture and PCR for bacteria, by microscopy and PCR for parasites and by immunoassay for detection of rotavirus A. Of the 437 samples analysed, 211 (48%) tested positive for diarrhoeagenic Escherichia coli, 96 (22%) for rotavirus A, 36 (8%) for Shigella spp., 17 (4%) for Salmonella spp., 8 (2%) for Campylobacter spp., 47 (11%) for Giardia intestinalis and 22 (5%) for Entamoeba histolytica. All isolates of E. coli (211, 100 %) and Salmonella (17, 100%), and 30 (83%) isolates of Shigella were sensitive to chloramphenicol; 17 (100%) isolates of Salmonella, 200 (94%) isolates of E. coli and (78%) 28 isolates of Shigella spp. were sensitive to gentamicin. In contrast, resistance to ampicillin was demonstrated in 100 (47%) isolates of E. coli and 16 (44%) isolates of Shigella spp. In conclusion, E. coli proved to be the main cause of diarrhoea in young children in this study, followed by rotavirus A and protozoa. Determination of diarrhoea aetiology and antibiotic susceptibility patterns of diarrhoeal pathogens and improved hygiene are important for clinical management and controlled strategic planning to reduce the burden of infection.

    We report the results of pneumococcal meningitis surveillance conducted at the Provincial Pediatric Hospital of Posadas, Misiones (Argentina), before the conjugate vaccine was introduced into the national vaccination schedule. Between January 1994 and December 2009, 167 cases of Streptococcus pneumoniae meningitis were diagnosed in children aged 1 month to 15 years. The attack rate/100,000 children ranged from 19.2 (1997) to 4.3 (2009), with a mean of 10.6 and a tendency to decrease (y=-0.689x+16.52). The number of cases per 100,000 children decreased from 146.6 to 34.8 and particularly involved the group of children aged 1 to 11 months (94/167, 56%). Thirty point seven percent (30.7%) (46/150) of the isolates were resistant to penicillin whereas 16.7% (25/150) were non-susceptible to cefotaxime. β-lactam resistance increased as from 1997 and began to decline in 2005. Nineteen serotypes were detected; type 14 was predominant and accounted for 32% (40/125). Eighty four point eight percent (84.8%) of the isolates were circumscribed to nine serotypes: 14, 5, 1, 7F, 18C, 6B, 9N, 9V and 4. Theoretical coverage for patients aged <2 years and >2 years was 84.1% (74/88) and 83.8% (31/37) for the 10-valent vaccine and 89.8 % (79/88) and 83.8% (31/37) for the 13-valent vaccine respectively. Penicillin resistance was restricted to 8 serotypes (14, 6B, 6A, 9V, 4, 23B, 19A1) and nonsusceptibility to cefotaxime was circumscribed to 3 serotypes (14, 9V and 1). This study will allow to evaluate the impact of the implementation of conjugate vaccines on our area.

    Colonization with mutans streptococci was studied in 1095 1-year-old children living in suburban Stockholm. During a scheduled vaccination appointment at a child health centre, a bacterial sample was obtained from the child's tongue and a structured questionnaire was completed by the accompanying parent. Six percent of the subjects were colonized with mutans streptococci. The variables most strongly correlated with presence of mutans streptococci were: non-Swedish background, consumption of sugar-containing beverages at night and total consumption of sugar-containing beverages. The results indicate that, by the age of 1 year, maternally influenced behaviour patterns such as dietary habits that may predispose to early colonization of mutans streptococci are already established. Such early colonization with mutans streptococci may predict high caries risk in the primary dentition.

    Context: Minimal access surgery (MAS) in children are common place and performed worldwide with gratifying results as the learning curve of the surgeon attains plateau. We share our experience of this technically evolving modality of surgery, performed at our setup over a period of 5 years. We also review and individually compare the data for commonly performed procedures with other available series. Author also briefly discuss potential advantages of MAS in certain debatable conditions performed quickly and with cosmesis as open procedure. Materials and methods: We performed 677 MAS in children aged between 7 days and 12 years. Five hundred and sixty-eight of these were Laparoscopic procedures and 109 were Video assisted thoracoscopic surgeries (VATS). In all laparoscopic procedures, the primary port placement was by the Hasson's open technique. We have used 5, 3 and 2 mm instruments. Our study include 259 inguinal hernia, 161 Appendectomies, 95 VATS for empyema, 51 orchiopexies, 49 diagnostic laparoscopy, 29 cholecystectomies, 22 adhesionlysis and other uncommonly performed procedures. Results: The ultimate outcome of all the performed procedures showed gratifying trend, the data of which are discussed in detail in the article. Conclusion: As we gained experience the operating time showed a decreasing trend, the complication rates and conversion rate also reduced. The advantages we came across were better postoperative appearances, less pain and early return to unrestricted activities. PMID:21188009

    The Canadian National Air Pollution Surveillance (NAPS) network operates five fine particulate matter (PM2.5) speciation sites in Ontario. Data from 2005 to 2010 from these sites were subjected to constrained positive matrix factorization (PMF) to obtain factors of particulate matter pollution. Eight factors were found to be common across the sites. These constrained factors were particulate sulfate and nitrate, aged combustion aerosols, biomass/wood combustion, non-ferrous metal smelting, crustal matter, steel works, and road salt. Other factors found at these sites were largely related to local sources in their respective neighbourhoods. Diagnostic results from constraining the PMF factors could be used to select the appropriate post-PMF analyses as they reveal the factors that were expected to have regional or local sources. Interpretation of the spatial trends of factors was guided by the extent of similarity of target ratios across the five sites as determined by their coefficient of variation (C.V.). On average, particulate sulfate had PM2.5 mass contributions that ranged from 7% (Wallaceburg) to 36% (Simcoe) and nitrate species ranged from 7% (Simcoe) to 23% (Windsor). A clear low rural - high urban divide for particulate nitrate was also observed. These non-uniform impacts across the sites indicate that a single representative location is not suitable for studying PM2.5 in Ontario. Temporal variations showed greater abundance of particulate sulfate in the summer and particulate nitrate in the winter respectively. Yearly median values of the sulfate factor that is largely energy-related have been declining for most sites since peaking in 2007. A trajectory ensemble model, simplified quantitative transport bias analysis (sQTBA) was used to identify potential source regions of the constrained sulfate and nitrate factors while radial plots of the conditional probability function (CPF) were used to explore the more locally-sourced factors.

    Particulate air pollution is becoming a serious public health concern in urban cities in India due to air pollution-related health effects associated with disability-adjusted life years (DALYs) and economic loss. To obtain the quantitative result of health impact of particulate matter (PM) in most populated Mumbai City and most polluted Delhi City in India, an epidemiology-based exposure-response function has been used to calculate the attributable number of mortality and morbidity cases from 1991 to 2015 in a 5-year interval and the subsequent DALYs, and economic cost is estimated of the health damage based on unit values of the health outcomes. Here, we report the attributable number of mortality due to PM10 in Mumbai and Delhi increased to 32,014 and 48,651 in 2015 compared with 19,291 and 19,716 in year 1995. And annual average mortality due to PM2.5 in Mumbai and Delhi was 10,880 and 10,900. Premature cerebrovascular disease (CEV), ischemic heart disease (IHD), and chronic obstructive pulmonary disease (COPD) causes are about 35.3, 33.3, and 22.9% of PM2.5-attributable mortalities. Total DALYs due to PM10 increased from 0.34 million to 0.51 million in Mumbai and 0.34 million to 0.75 million in Delhi from average year 1995 to 2015. Among all health outcomes, mortality and chronic bronchitis shared about 95% of the total DALYs. Due to PM10, the estimated total economic cost at constant price year 2005 US$ increased from 2680.87 million to 4269.60 million for Mumbai City and 2714.10 million to 6394.74 million for Delhi City, from 1995 to 2015, and the total amount accounting about 1.01% of India's gross domestic product (GDP). A crucial presumption is that in 2030, PM10 levels would have to decline by 44% (Mumbai) and 67% (Delhi) absolutely to maintain the same health outcomes in year 2015 levels. The results will help policy makers from pollution control board for further cost-benefit analyses of air pollution management programs in Mumbai and Delhi.

    This is a retrospective study of 55 children under the age of 2 years diagnosed with Langerhans cell histiocytosis (LCH). They were classified according to age and organ function and dysfunction following Lahey's criteria. The studied population was divided into four groups by age of diagnosis (0-6, 7-12, 13-18, and 19-24 months). Statistical analysis showed no significant difference in outcome between age groups, although the population under 6 months had a 81.3% fatality rate. The presence of organ dysfunction was a major cause of death in all age groups, being statistically significant in outcome (P > 0.005) compared with patients without organ dysfunction. The presence of thrombocytopenia and/or respiratory dysfunction was also highly associated with a fatal outcome. In the surviving population, no second malignancies have been reported. The late secondary effects of therapy include endocrine, orofacial, and osseous pathologies.

    Abstract Background: To understand whether the relationship between young children's autonomic nervous system (ANS) responses predicted their BMI, or vice versa, the association between standardized BMI (zBMI) at 2, 3.5, and 5 years of age and ANS reactivity at 3.5–5 years of age, and whether zBMI predicts later ANS reactivity or whether early ANS reactivity predicts later zBMI, was studied. Methods: Low-income, primarily Latino children (n=112) were part of a larger cohort study of mothers recruited during early pregnancy. Study measures included maternal prenatal weight, children's health behaviors (i.e., time watching television, fast food consumption, and time playing outdoors), children's height and weight at 2, 3.5, and 5 years, and children's ANS reactivity at 3.5 and 5 years. ANS measures of sympathetic nervous system (i.e., pre-ejection period) and parasympathetic nervous system (i.e., respiratory sinus arrhythmia) activity were monitored during rest and four challenges. Reactivity was calculated as the difference between mean challenge response and rest. Structural equation models analyzed the relationship between children's zBMI at 2, 3.5, and 5 years and ANS reactivity at 3.5 and 5 years, adjusting for mother's BMI, children's behaviors, and changes in height. Results: There was no association between zBMI and ANS cross-sectionally. Children with high zBMI at 2 or 3.5 years or large zBMI increases from 2 to 3.5 years of age had decreased sympathetic activity at 5 years. Neither sympathetic nor parasympathetic reactivity at 3.5 years predicted later zBMI. Conclusions: Increased zBMI early in childhood may dampen young children's SNS responses later in life.

    Breastfeeding is the fundamental component of child survival strategy. It significantly influences neurological development of children. The study was conducted to assess whether exclusive and prolonged breastfeeding improves children's cognitive development, including low birth weight (LBW) babies, in a developing country setting like Bangladesh. This observational study was done on a cohort of newborn infants who were discharged from the special care baby unit of Dhaka Shishu Hospital during January 2006 to December 2008 with proper counseling about exclusive and prolonged breastfeeding. Their neuro-developmental follow-up was started at 4 weeks postnatal age and continued at 3-monthly intervals up to 1 year of age. At each visit, cognitive development was assessed using the Bayley Scales of Infant Development (BSID II). Cognitive development was compared between the babies of exclusive vs. non exclusive breastfeeding, normal weight vs. low birth weight and male vs. female babies. A total of 105 cases were successfully followed-up during this period. Out of these 47(44.8%) babies were exclusively breastfed up to 6 month of age and 58(55.2%) were in nonexclusive group. Overall Psychomotor Development Index (PDI) was slightly more (108.40 ± 23.06 vs. 103.23 ± 19.87) in the exclusive breast fed babies in comparison to nonexclusive breast fed babies, but was significantly more in babies having birth weight >2.5 kg in comparison to those having birth weight of <2.5 kg. Other parameters of cognitive development were more or less same in both normal and LBW groups. Mental and motor development was same in both boys and girls. In behavior ratings, cooperation was significantly high (5.89 ± 2.54 vs. 4.71 ± 3.13, p=0.05) and vocalization (5.89 ± 1.07 vs. 4.58 ± 1.16) was also high, though not significant, in girls than boys.

    Age and portion size have been found to influence food intake in American children but have not been examined in an international context. This study evaluated the association between age and the effects of portion size on the food intake of kindergarteners in Kunming, China. Using a within-subjects crossover design in a classroom setting, 173 children in two age groups, mean age 4.2 years and 6.1 years, were served a predefined reference, small (-30%) and large (+30%) portion of rice, vegetables, and a protein source during lunchtime over three consecutive days. Each portion was weighed before and after the meal to determine amount of food consumed. Linear mixed modeling, controlling for repeated measures and clustering by classroom, was used to compare food intake under small and large portion size conditions to the reference portion. Children ate significantly less food when served small portions. When served a large portion, 6-year-old children increased food intake while 4-year-old children decreased food intake in comparison to the reference portion. Findings indicate that portion size affects food intake in Chinese children 4-6-years old. Older children show larger increases in food intake with increased portion size than do younger children.

    This study describes on-road measurements of fine particulate matter (PM2.5) using a mobile instrumentation platform to assess the chemical composition and oxidative potential of PM2.5, using the dithiothreitol (DTT) assay, over three representative roadways in the Los Angeles Basin: the I-110 and I-710 freeways, the Wilshire/Sunset boulevards as well as the main campus of the University of Southern California (USC), used as a reference urban background site. Samples were chemically analyzed for elemental carbon (EC), organic carbon (OC), polycyclic aromatic hydrocarbons (PAHs) and 50 elements. The cumulative mass fraction of the measured PAHs was highest on the freeways (0.16 ± 0.01 and 0.15 ± 0.01 ng/μg PM, on I-110 and I-710, respectively); which on average was 3 and 3.3-fold higher than at Wilshire/Sunset and USC site, respectively. Mass fractions of Ba, Cr, Cu, Mn, Ni, Pb, Sb and Zn, tracers of vehicular abrasion, were 3.8 ± 0.8 times higher on both freeways in comparison to Wilshire/Sunset. The observed intrinsic (normalized per PM mass) DTT activity was greatest on freeways, averaging 30.13 ± 3.15 nmol/min mg PM and being roughly 1.9 and 2.1 times higher than the values obtained at Wilshire/Sunset and USC, respectively. Furthermore, comparison of our results with previous on-road and roadside studies conducted in the last decade in Los Angeles indicated an overall reduction in the contribution of carbonaceous species and PAHs (important tracers of exhaust emissions) to PM mass, especially on I-710 freeway with the higher heavy-duty diesel vehicle fraction, indicating the effectiveness of diesel vehicle emissions control policies implemented in recent years in California. In contrast, greater contributions of certain groups of metals and trace elements that are indicators of non-tailpipe emissions compared to previous studies provide evidence on the increasing importance of non-tailpipe emissions to the oxidative potential of on-road PM2.5 as vehicular

    Sakellaris, George S; Charissis, Giorgos C

    2008-07-01

    The aim of the study was to compare historical features, physical examination findings, and testicular color Doppler ultrasound in pediatric patients with epididymitis compared to testicular torsion and torsion of the appendix testes. A retrospective review of the medical records of 66 boys presenting with clinical aspects of acute scrotum over a 3-year period was performed. Sixty-six patients were included in the study (29 with epididymitis, 8 with testicular torsion and 12 with torsion of the appendix testis, 4 with scrotal abscesses, 5 with scrotal swelling, and 1 with inflamed epididymal cyst). The duration of symptoms ranged from 6 h to 4 days with a peak on the second day. Urine cultures and viral testes were negative in all patients. Color Doppler ultrasound was diagnostic for epididymitis in 28 patients (96.6%). Systemic intravenous antibiotics were given in all 29 patients with epididymitis. No patient showed signs of testicular atrophy in the follow-up. The increasing incidence of epididymitis should question the policy of routine exploration of the acute scrotum in children. The history and physical examination cannot reliably identify those boys who can be managed conservatively. Color Doppler ultrasound is a useful adjunct in the evaluation of the acute scrotum when physical findings are equivocal but it can also be misleading.

    Loret de Mola, Christian; Quispe, Renato; Valle, Giancarlo A.; Poterico, Julio A.

    2014-01-01

    Background Rapid urbanization, increase in food availability, and changes in diet and lifestyle patterns have been changing nutritional profiles in developing nations. We aimed to describe nutritional changes in children under 5 years and women of reproductive age in Peru, during a 15-year period of rapid economic development and social policy enhancement. Materials and Methods Trend analyses of anthropometric measures in children of preschool age and women between 15–49 years, using the Peruvian National Demographic and Family Health Surveys (DHS) from 1996 to 2011. WHO growth curves were used to define stunting, underweight, wasting and overweight in children <5y. We employed the WHO BMI-age standardized curves for teenagers between 15–19y. In women >19 years, body mass index (BMI) was analyzed both categorically and as a continuous variable. To statistically analyze the trends, we used regression models: Linear and Poisson for continuous and binary outcomes, respectively. Results We analyzed data from 123 642 women and 64 135 children, from 1996 to 2011. Decreases over time were evidenced for underweight (p<0.001), wasting (p<0.001), and stunting (p<0.001) in children under 5y. This effect was particularly noted in urban settings. Overweight levels in children reduced (p<0.001), however this reduction stopped, in urban settings, since 2005 (∼12%). Anemia decreased in children and women (p<0.001); with higher reduction in urban (↓43%) than in rural children (↓24%). BMI in women aged 15–19 years increased (p<0.001) across time, with noticeable BMI-curve shift in women older than 30 years. Moreover, obesity doubled during this period in women more than 19y. Conclusion Nutrition transition in Peru shows different patterns for urban and rural populations. Public policies should emphasize targeting both malnutrition conditions—undernutrition/stunting, overweight/obesity and anemia—considering age and place of residence in rapid developing societies

    Yee, R; David, J; Khadka, R

    2006-09-01

    The aim of the study was to evaluate the oral cleanliness of school children in the District of Sunsari, Nepal. A multi-stage random sampling oral epidemiological survey was conducted in private and government, urban, rural town and rural village schools in 15 illakas of Sunsari District, Eastern Nepal. A total of 600, 12-13-year-old and 600 15-year-old school children were examined by trained examiners using the simplified oral hygiene index (OHI-S). The average age-group, debris and calculus index scores were combined to obtain the simplified oral hygiene index (OHI-S). The mean OHI-S scores were compared and evaluated using the parametric t-test for two independent samples. The mean OHI-S for urban 12-13-year-old school children was 0.98 compared to 1.34 for school children of rural towns and 1.44 for school children of rural villages and these differences in mean OHI-S were statistically significant (P < 0.005). In the 15-year-old age group, urban school children had a mean OHI-S score of 1.00 compared to 1.37 for rural towns and 1.43 for rural villages. The variance in the mean OHI-S scores were statistically significant (P < 0.005). The overall level of cleanliness in the school children surveyed was good. Children of urban schools had the lowest scores followed by school children from rural towns and then rural villages. When the mean OHI-S scores were compared with the DMFT scores, there was an inverse relationship between oral cleanliness and dental caries. Frequency of sugar consumption and the availability and affordability of fluoridated toothpaste may be important factors in the development of dental caries than oral cleanliness.

    PubMed

    Gulsrud, Amanda C; Hellemann, Gerhard S; Freeman, Stephanny F N; Kasari, Connie

    2014-04-01

    This study follows 40 children who were participants in a randomized controlled early intervention trial (Kasari et al.) from early childhood (2-5 years of age) to elementary school age (8-10 years). To fully utilize the available longitudinal data, the general linear mixed model was the primary analytical approach. The growth trajectories of joint attention skills (pointing, coordinated joint looking, and showing) and expressive language outcomes in these children were estimated based on five time points during the measurement period. The children were grouped by diagnosis at the last follow-up (autism, autism spectrum disorder (ASD), no diagnosis) and by their original treatment group assignment (joint attention, symbolic play, control), and differences between these groups were evaluated. Results showed that joint attention skills of coordinated joint looking and showing increased over time, and pointing to share interest increased over the first year measured and decreased thereafter. These trajectories were influenced by both original treatment assignment and diagnostic status at follow-up. In addition, a cross-lagged panel analysis revealed a causal relationship between early pointing and later language development. This study highlights the longitudinal and developmental importance of measures of early core deficits in autism, and suggests that both treatment and ASD symptomatology may influence growth in these skills over time.

  17. Maternal diabetes status does not influence energy expenditure or physical activity in 5-year-old Pima Indian children.

    PubMed

    1998-10-01

    Children of women who have diabetes during pregnancy are more likely to become obese by early adulthood than those of women with normal glucose tolerance during pregnancy. Obesity can result from either excess food intake, low levels of energy expenditure or both. In our study, we tested whether maternal diabetes status influences total energy expenditure (TEE by doubly labelled water), resting metabolic rate (RMR by ventilated hood) and physical activity level (PAL = TEE/RMR and assessed by activity questionnaire). Measurements were taken in 88 5-year-old Pima Indian children, 24 children of women with diabetes (2-h plasma glucose > or = 11.1 mmol/l) diagnosed before or during pregnancy and 64 children of women with normal glucose tolerance (2-h plasma glucose < 7.8 mmol/l during pregnancy and no prior history of abnormal glucose tolerance). Although birth weight was higher in children of diabetic than of nondiabetic women (mean +/- SD; 3.8 +/- 0.6 vs 3.5 +/- 0.4 kg, p < 0.03), there were no differences in weight (26.4 +/- 6.9 vs 24.2 +/- 5.6 kg) or per cent body fat (18O dilution; 33 +/- 8 vs 31 +/- 8%) between the groups at 5 years of age. There was no difference in TEE (6508 +/- 1109 vs 6175 +/- 942 kJ/d) or in RMR (4674 +/- 786 vs 4483 +/- 603 kJ/d) expressed as absolute values or after adjustment for weight and sex (TEE) or fat-free mass, fat mass, and sex (RMR). Physical activity level was also similar between the groups (1.40 +/- 0.12 vs 1.38 +/- 0.12). These results suggest that maternal diabetes status does not influence energy expenditure in the children by 5 years of age. Thus the greater obesity seen at older ages in the children of women with diabetes could be due to excess energy intake. Alternatively, if energy expenditure does have a role in the aetiology of obesity in these children, perhaps it does so only in older children.

    Autism is a neurodevelopmental disability that may affect nutritional management of children with autism. This study aimed to compare the nutritional status of children with autism with that of typically developing children (aged 4-6 years) in China. Nutritional status was assessed by means of nutritional data, anthropometric data, biochemical assessment, physical examination for nutrient deficiencies and providing a questionnaire to parents. A total of fifty-three children with autism and fifty-three typically developing children were enrolled in this study. The parents were asked to complete the questionnaire regarding the eating behaviour and gastrointestinal symptoms of their children. They were also asked to provide a 3 d food diary. Children with autism exhibited several abnormalities in terms of eating behaviour and gastrointestinal symptoms. The levels of vitamins A and B6, Zn and Ca intakes were <80 % of the dietary reference intakes in both groups. In addition, the proportions of vitamin C and Ca intake deficiencies in the autism group were significantly higher than those in the control group. Serum Zn level was less than the normal reference range in both the groups. Serum Ca, vitamin A and folate levels in children with autism were significantly lower when compared with children without autism. According to the anthropometric data, the mean BMI, weight-for-height Z-score (Z WH) and BMI for age Z-score (Z BMIA) of children with autism were significantly higher than those of the typically developing children. Thus, nutritional inadequacies were observed in children with autism and typically developing children in China, which were, however, more pronounced among children with autism.

    The aim of the study was to examine predictors of eating disorder symptoms in a population based sample at the earliest age at which they can be measured using the Children's Eating Attitudes Test. Data were collected from the longitudinal Gateshead Millennium Study cohort; 609 children participated in the 7 year data sweep (and their mothers and teachers), and 589 children participated in the 9 year data sweep. Eating disorder symptoms at 9 years were higher in boys, and in children from more deprived families. Higher eating disorder symptoms were associated with more body dissatisfaction at 9 years. Higher symptoms were predicted by higher levels of dietary restraint and of emotional symptoms, but not greater body dissatisfaction, 2 years earlier. The study showed that some correlates of high eating disorder symptoms found in adolescents and adults are also found in children, before the rise in diagnosable eating disorders over the pubertal period.

    A total of 465 children aged 8 to 10 years were vaccinated with 2 doses of Recombivax-HB 2.5 microg (RB) or Twinrix-Junior 10 microg/360 EL.U (TX), according to a 0 and 6 months schedule. Seven years postsecond dose, a challenge dose of vaccine was given. All vaccinees in the TX and 98% in the RB group showed an anamnestic response. Vaccination at the age of 8 to 10 years with two-pediatric doses of TX or RB given with a 6 months interval induces a long-lasting immunity in most vaccinees.

    Purpose. To examine the association of the Family Nutrition and Physical Activity (FNPA) screening tool, a behaviorally based screening tool designed to assess the obesogenic family environment and behaviors, with cardiovascular disease (CVD) risk factors in 10-year old children. Methods. One hundred nineteen children were assessed for body mass index (BMI), percent body fat (%BF), waist circumference (WC), total cholesterol, HDL-cholesterol, and resting blood pressure. A continuous CVD risk score was created using total cholesterol to HDL-cholesterol ratio (TC:HDL), mean arterial pressure (MAP), and WC. The FNPA survey was completed by parents. The associations between the FNPA score and individual CVD risk factors and the continuous CVD risk score were examined using correlation analyses. Results. Approximately 35% of the sample were overweight (19%) or obese (16%). The mean FNPA score was 24.6 +/- 2.5 (range 18 to 29). Significant correlations were found between the FNPA score and WC (r = -.35, p<.01), BMI percentile (r = -.38, p<.01), %BF (r = -.43, p<.01), and the continuous CVD risk score (r = -.22, p = .02). No significant association was found between the FNPA score and TC:HDL (r=0.10, p=0.88) or MAP (r=-0.12, p=0.20). Conclusion. Children from a high-risk, obesogenic family environment as indicated with a lower FNPA score have a higher CVD risk factor profile than children from a low-risk family environment.

    Understanding the cultural and linguistic diversity of young children with hearing loss informs the provision of assessment, habilitation, and education services to both children and their families. Data describing communication mode, oral language use, and demographic characteristics were collected for 406 children with hearing loss and their caregivers when children were 3 years old. The data were from the Longitudinal Outcomes of Children with Hearing Impairment (LOCHI) study, a prospective, population-based study of children with hearing loss in Australia. The majority of the 406 children used spoken English at home; however, 28 other languages also were spoken. Compared with their caregivers, the children in this study used fewer spoken languages and had higher rates of oral monolingualism. Few children used a spoken language other than English in their early education environment. One quarter of the children used sign to communicate at home and/or in their early education environment. No associations between caregiver hearing status and children's communication mode were identified. This exploratory investigation of the communication modes and languages used by young children with hearing loss and their caregivers provides an initial examination of the cultural and linguistic diversity and heritage language attrition of this population. The findings of this study have implications for the development of resources and the provision of early education services to the families of children with hearing loss, especially where the caregivers use a language that is not the lingua franca of their country of residence.

    Endoscopic treatment for vesicoureteral reflux (VUR) has become an established alternative to long-term antibiotic prophylaxis and ureteral reimplantation. We present the outcome of endoscopic treatment with dextranomer/hyaluronic acid copolymer (Deflux) for VUR in children by a single surgeon at our institute from October 2003 to October 2009. We reviewed the cases of 150 patients (total 239 ureters), 56 girls (37%) and 94 boys (63%), with a mean age of 2.2 years and a median followup of 2.5 years (range 3-68 months). Among the 239 ureters treated, 67.4% (161/239) were cured with a single injection, and a second and third injection raised the cure rate to 86.6% (207/239) and 88.3% (211/239), respectively. None had postoperative ureteral obstruction.

    Abstract Objective: Investigate hearing function and headphone listening habits in nine-year-old Swedish children. Design: A cross-sectional study was conducted and included otoscopy, tympanometry, pure-tone audiometry, and spontaneous otoacoustic emissions (SOAE). A questionnaire was used to evaluate headphone listening habits, tinnitus, and hyperacusis. Study sample: A total of 415 children aged nine years. Results: The prevalence of a hearing threshold ≥20 dB HL at one or several frequencies was 53%, and the hearing thresholds at 6 and 8 kHz were higher than those at the low and mid frequencies. SOAEs were observed in 35% of the children, and the prevalence of tinnitus was 5.3%. No significant relationship between SOAE and tinnitus was found. Pure-tone audiometry showed poorer hearing thresholds in children with tinnitus and in children who regularly listened with headphones. Conclusion: The present study of hearing, listening habits, and tinnitus in nine-year old children is, to our knowledge, the largest study so far. The main findings were that hearing thresholds in the right ear were poorer in children who used headphones than in children not using them, which could be interpreted as headphone listening may have negative consequences to children’s hearing. Children with tinnitus showed poorer hearing thresholds compared to children without tinnitus. PMID:27329351

    In the present study, predictors of persistent conduct problems among children aged 4-8 years were investigated in a randomized controlled trial 1 year after treatment with the Incredible Years parent training program (PT), or combined parent training and child treatment (PT + CT). Data were collected before and after treatment and at a 1-year follow-up. Pre-treatment child characteristics predicting persistent conduct problems in the child at the 1-year follow-up were high levels of internalizing and aggression problems as reported by mothers. The only family characteristic predicting persistence of child conduct problems was having contacts with child protection services. Clinicians and researchers need to closely monitor and identify children with conduct problems not responding to parent training programs. These individuals and their families are likely to need further support.

    The clinical profile and outcome of neuroblastoma in 103 children, older than one-year is presented. 74 had Stage IV, 27 Stage III and one patient each had Stage I or II disease. Treatment included chemotherapy followed by surgical resection/debulking. Radiotherapy was administered to those with residual tumor. Chemotherapy consisted of OPEC (vincristine, cyclophosphamide, cisplatin and etoposide). The caretakers of 54 (52.4%) children either did not opt for or defaulted therapy, whilst 3 patients died before chemotherapy could be initiated. Of the remaining 46 patients, the tumor progressed during therapy in 19 (41.3%). Relapse of disease was documented in 22 (47.8%) cases. Merely 4 (8.7%) children are disease free for a period of 16.5+/-6.7 months. Majority of children presented with advanced disease and the outcome was dismal with conventional non-myloablative chemotherapy.

    In this article, we have explored 5-year-old children's expressions when they as actors took part in an immunization situation in the Primary Child Health Care (PCHC) service in Sweden. Although children's health and development are the main concern in the PCHC service, their perspectives in such a setting have not been explored fully. To capture children's perspectives we used a hermeneutic design and video observations. The findings revealed children as competent and active participants, contributing to the construction of the PCHC situation in mutuality with the nurse and the parent. The conceptualization of children's expressions and actions revealed how they influenced and dealt with a PCHC situation by using strategies of tuning-in, affirmative negotiation, and delaying negotiation. Understanding children's actions will assist nurses to act with sensitivity when they encounter and support children.

    The Community Multiscale Air Quality (CMAQ) and the Sparse Matrix Operator Kernel Emissions (SMOKE) modeling systems were used to simulate emissions and air quality in North Eastern Alberta where a rapid rise in oil sands development has caused air quality concerns over the last decade. The models were run on a 36/12/4 km domain for the four month period of May through August 2002. A model performance evaluation was conducted by comparing the CMAQ model estimates against ambient air quality measurements. In the Alberta oil sands region, the model tended to achieve or nearly achieve ozone model performance goals, albeit with an underestimation bias. The magnitudes of the observed PM2.5 concentrations were matched by the modeling system, except when the observed PM2.5 concentrations were influenced by emissions from forest fires in which case the model underestimated the observed PM2.5 concentrations. The CMAQ-estimated 4th highest daily maximum 8-hour ozone concentrations in the oil sands region were below the 65 ppb Canada Wide Standard (CWS) as well as the 58 ppb Alberta Management Plan Trigger Level. The highest estimated ozone concentrations occurred near the oil sands development area just north of Fort McMurray with values approaching, but below, the 58 ppb Management Plan Trigger Level; estimated ozone concentrations are much lower in the farther northern portions of the oil sands region. The acute (i.e., maximum 3-day value) SUM60 vegetative ozone exposure metric was mostly less than 100 ppb h, which is below the threshold of concern for crops. However, just north of Fort McMurray there were small areas where the acute SUM60 metric exceeded the 500-700 ppb h threshold of concern for crops with maximum values in plumes from sources in the oil sands mine area of ˜900 ppb h. The maximum chronic (three-month average) SUM60 ozone exposure metric was below the thresholds of concern. The CMAQ-estimated maximum 98th percentile 24-hour average PM2.5 concentration

    Binge eating is common in middle childhood (6-12 years) and often presents in concert with disordered eating attitudes, emotional distress, overweight and adiposity. Binge eating is also predictive of excessive weight gain and is associated with energy intake. However, few children meet DSM-IV-TR criteria for binge eating disorder, thereby making treatment recommendations a challenge. We propose criteria for a new diagnosis, Loss of Control Eating Disorder in Children age 12 years and younger, for further study. The criteria put forward are a revision of Marcus and Kalarchian's [Marcus, M.D., & Kalarchian, M.A. (2003). Binge eating in children and adolescents. International Journal of Eating Disorders, 34 Suppl, S47-S57.] provisional binge eating disorder research criteria for children 14 years and younger, and are based upon the evolving literature in children with binge and loss of control eating episodes. A rationale for the new criteria set is provided, and future research directions are proposed.

    Objective: The present study aimed to assess the prevalence of decreased visual acuity, strabismus, and spectacle wear in children aged 5 to 13 years. Methods: A cross-sectional study was performed in primary education schools. A total of 1938 participants, including 940 females (48.5%) and 998 males (51.5%) with a mean age 8.96 ± 2.31 (5-13 years old), were screened. The comparisons were performed with gender, age, and age groups. The children attended to vision screening were assigned to three age groups as 5-6 years, 7-9 years, and 10-13 years. Results: The prevalence of the parameters was detected as decreased visual acuity 12.4%, strabismus 2.2%, and spectacle wear 6.9%. The prevalence of decreased visual acuity was significantly higher in girls and in children aged 7-9 years old (p = 0.013, p < 0.001). The prevalence of spectacle wear was significantly higher in girls and in children aged 7-9 years old (p = 0.019, p < 0.001). There was a visual acuity decrease in 33 of 106 (31.1%) children despite wearing own spectacle. There was no significant difference among three age groups for strabismus. Conclusion: Increased prevalence of decreased visual acuity, as well as the higher frequency of spectacle wear in children at ages of 7-9 years old may point out a threshold for visual impairment.

    It is the position of the American Dietetic Association that children ages 2 to 11 years should achieve optimal physical and cognitive development, attain a healthy weight, enjoy food, and reduce the risk of chronic disease through appropriate eating habits and participation in regular physical activity. The health status of American children has generally improved during the past 3 decades. However, the number of children who are overweight has more than doubled among 2- to 5-year-old children and more than tripled among 6- to 11-year-old children, which has major health consequences. This increase in childhood overweight has broadened the focus of dietary guidance to address children's overconsumption of energy-dense, nutrient-poor foods and beverages and physical activity patterns. Health promotion will help reduce diet-related risks of chronic degenerative diseases, such as cardiovascular disease, type 2 diabetes, cancer, obesity, and osteoporosis. This position reviews what US children are eating and explores trends in food and nutrient intakes as well as the impact of school meals on children's diets. Dietary recommendations and guidelines and the benefits of physical activity are also discussed. The roles of parents and caregivers in influencing the development of healthful eating behaviors are highlighted.

    Objective To identify the prevalence and predictors of malnutrition among 2-year old children in the Western Highlands of Guatemala. Methods Prospective cohort of 852 Guatemalan children in San Lucas Toliman, Guatemala followed from birth to age 2 from May 2008 to December 2013. Socio-demographic, anthropometric, and health data of children was collected at 2 month intervals. Results Among the 402 males and 450 females in the cohort, mean weight-for-age Z-score (WAZ) declined from -0.67 ± 1.01 at 1 year to -1.07 ± 0.87 at 2 years, while mean height-for-age Z-score (HAZ) declined from -1.88 ± 1.19 at 1 year to -2.37 ± 0.99 at 2 years. Using multiple linear regression modeling, number of children <5 years old, vomiting in the past week, fever in the past week, and WAZ at 1 year were significant predictors of WAZ at 2 years. Significant predictors of HAZ at 2 years included household size, number of children <5 years old, diarrhea in the past week, WAZ at 1 year, and HAZ at 1 year. Vomiting in the past week and WAZ at 1 year were significant predictors of weight-for-height z-score (WHZ) at 2 years. Conclusions Number of children <5 years old, symptoms such as vomiting or diarrhea in the previous week, and prior nutritional status were the most significant predictors of malnutrition in this cohort. Future research may focus on the application of models to develop predictive algorithms for mobile device technology, as well as the identification of other predictors of malnutrition that are not well characterized such as the interaction of environmental exposures with protein consumption and epigenetics.

    We reported previously that radiocesium ((137)Cs) concentrations in earthworms increased with those in litter and/or soil in Fukushima Prefecture forests 0.5 y after the Fukushima Dai-ichi Nuclear Power Plant (FDNPP) accident. This study provides further results for 1.5 and 2.5 y after the accident and discusses temporal changes in (137)Cs concentrations and transfer factors (TF) from litter to earthworms to better understand the mechanisms by which (137)Cs enters soil food webs. The concentration of (137)Cs in accumulated litter on the forest floor rapidly decreased, and the concentration in soil (0-5-cm depth) increased over time from 0.5 to 1.5 y, but changed only moderately from 1.5 to 2.5 y. The concentration of (137)Cs in earthworms consistently decreased during the study period; values 2.5 y after the accident were 18.8-68.5% of those 0.5 y after the accident. The TFs from accumulated litter to earthworms decreased over time: 0.24 ± 0.08 (mean ± SD) at 0.5 y and 0.16 ± 0.04 at 2.5 y. This decrease may be a result of decreases in the bioavailability of (137)Cs in litter and the surface soil layer. Changes in (137)Cs bioavailability should be continuously tracked to determine any changes in the relationship between radiocesium concentrations in earthworms and that in accumulated litter or soil.

  4. Social conformity persists at least one day in 6-year-old children.

    PubMed

    Sun, Sai; Yu, Rongjun

    2016-12-21

    Humans have a tendency to forgo their own attitudes or beliefs in order to better align with the interests of a majority, a behavioral process known as conformity. Social conformity has been widely studied among adults and adolescents, whereas experimental studies on the impact of peer influence among young children have been relatively limited. The current study aims to investigate both short-term and sustained conforming behaviors among children in situations of relatively low social pressure. Forty-one children aged 5 to 6 years rated the attractiveness of 90 faces presented serially followed by witnessing a group rating in the absence of peers. Subsequently, second judgement was made after 30 minutes (Experiment 1). Results show that 6-year-old children tended to conform to their peers when group ratings differed from their own ratings, while younger children did not. In Experiment 2, children were required to make the second judgment one day after exposure to group ratings. Similarly, children aged 6 years exhibited a sustained conformity effect even after one day. Our findings suggest that 6-year-old children spontaneously change their private opinions under implicit social influence from peers.

    Comparative optimism has been studied extensively in adults and is a significant component of social- cognitive models about health. In contrast, little is known about comparative optimism in children or about the wider social- cognitive processes that underpin their health-related behavior. This study investigated comparative optimism for health- and nonhealth-related topics in 101 children 8 or 9 years of age, the youngest ages that have been investigated so far. Children were shown to be unrealistically optimistic for health and nonhealth events. The implications of these findings for understanding comparative optimism in children are discussed.

    Receptive vocabulary develops rapidly in early childhood and builds the foundation for language acquisition and literacy. Variation in receptive vocabulary ability is associated with variation in children's school achievement, and low receptive vocabulary ability is a risk factor for under-achievement at school. In this study, bivariate and multivariate growth curve modelling was used to estimate trajectories of receptive vocabulary development in relation to a wide range of candidate child, maternal and family level influences on receptive vocabulary development from 4-8 years. The study sample comprised 4332 children from the first nationally representative Longitudinal Study of Australian Children (LSAC). Predictors were modeled as risk variables with the lowest level of risk as the reference category. In the multivariate model, risks for receptive vocabulary delay at 4 years, in order of magnitude, were: Maternal Non- English Speaking Background (NESB), low school readiness, child not read to at home, four or more siblings, low family income, low birthweight, low maternal education, maternal mental health distress, low maternal parenting consistency, and high child temperament reactivity. None of these risks were associated with a lower rate of growth from 4-8 years. Instead, maternal NESB, low school readiness and maternal mental health distress were associated with a higher rate of growth, although not sufficient to close the receptive vocabulary gap for children with and without these risks at 8 years. Socio-economic area disadvantage, was not a risk for low receptive vocabulary ability at 4 years but was the only risk associated with a lower rate of growth in receptive vocabulary ability. At 8 years, the gap between children with and without socio-economic area disadvantage was equivalent to eight months of receptive vocabulary growth. These results are consistent with other studies that have shown that social gradients in children's developmental outcomes

    Investigating cognitive development of children poses interesting challenges pertaining to emergence of children's' ability to think and understand. Psychological tasks that involve conflict, like the Flanker task, are widely used to understand development of response conflict processes. In this study, EEG signals were used to examine the coherence and imaginary part of coherency within the delta, theta, alpha and beta bands across different conditions of the Flanker task. Longitudinal data were collected from a group of typically developing children at ages of seven and nine. We found that the imaginary part of coherency was more helpful in distinguishing between stimuli - alpha and beta bands resulted in 90.90% classification rate in seven year old children. The beta and theta bands were found to be more effective for stimuli classification in nine year old children - more than 84.09% classification accuracy was achieved.

    This research examined the overtime reciprocal relations between maternal and paternal harsh discipline and children's externalizing behavior. Seven hundred two father-mother dyads of children (6-9 years of age at baseline) completed measures of parental harsh discipline and children's externalizing behavior at five time points, 1 year apart. Autoregressive latent trajectory models revealed that maternal and paternal corporal punishment predicted subsequent children's externalizing behavior (parent-driven effects), whereas children's externalizing behavior predicted subsequent maternal and paternal psychological aggression (child-driven effects). The parent-driven effects became stronger, whereas the child-driven effects were equally strong across time. Furthermore, the parent-driven effects for corporal punishment were found for both boys and girls, whereas the child-driven effects for psychological aggression were found only for boys.

    In a previous study, we compared the effects of just over one year of intensive behavior analytic intervention (IBT) provided to 29 young children diagnosed with autism with two eclectic (i.e., mixed-method) interventions (Howard, Sparkman, Cohen, Green, & Stanislaw, 2005). One eclectic intervention (autism programming; AP) was designed specifically for children with autism and was intensive in that it was delivered for an average of 25-30 h per week (n = 16). The other eclectic intervention (generic programming; GP) was delivered to 16 children with a variety of diagnoses and needs for an average of 15-17 h per week. This paper reports outcomes for children in all three groups after two additional years of intervention. With few exceptions, the benefits of IBT documented in our first study were sustained throughout Years 2 and 3. At their final assessment, children who received IBT were more than twice as likely to score in the normal range on measures of cognitive, language, and adaptive functioning than were children who received either form of eclectic intervention. Significantly more children in the IBT group than in the other two groups had IQ, language, and adaptive behavior test scores that increased by at least one standard deviation from intake to final assessment. Although the largest improvements for children in the IBT group generally occurred during Year 1, many children in that group whose scores were below the normal range after the first year of intervention attained scores in the normal range of functioning with one or two years of additional intervention. In contrast, children in the two eclectic treatment groups were unlikely to attain scores in the normal range after the first year of intervention, and many of those who had scores in the normal range in the first year fell out of the normal range in subsequent years. There were no consistent differences in outcomes at Years 2 and 3 between the two groups who received eclectic interventions

    Respiratory syncytial virus (RSV) is the most frequent agent of acute lower respiratory diseases and creates a significant burden of disease in children under 5 years all over the world. RSV causes severe lower respiratory tract infections (LRTI) that require hospitalization, especially in children ≤2 years. The aim of this study was to determine the incidence of RSV in children ≤2 years of age hospitalized for LRTI. Children ≤2 years of age hospitalized for one year for LRTI in the three largest hospitals of Bursa City Center, Turkey were evaluated. These three hospitals comprise 67.5% of all child beds in central Bursa, so this study allows us to evaluate the total disease burden and hospitalization incidence in central Bursa. Nasal swabs of the children were evaluated with RSV Respi- Strip (Coris Bioconcept Organization). A total of 671 children were hospitalized for LRTI, and 254 (37.9%) had at least one hospitalization that was positive for RSV. Of all patients with LRTI, 54.8% (368/671) were hospitalized for acute bronchiolitis, while 45.2% (303/671) were hospitalized for pneumonia. Of patients with acute bronchiolitis or pneumonia, 41% (151/368) and 34% (103/303) were RSV+, respectively. Of RSV+ hospitalized children, 59.5% (151/254) were diagnosed as acute bronchiolitis and 40.5% (103/254) as pneumonia. The annual incidences of hospitalization due to LRTI, acute bronchiolitis and pneumonia were 20.5/1000, 11.2/1000 and 9.3/1000, respectively, in children ≤2 years of age. The annual incidences of hospitalization due to RSV+ LRTI, acute bronchiolitis and pneumonia were found as 7.8/1000, 4.6/1000 and 3.2/1000, respectively, in children ≤2 years of age. More than one-third of all children hospitalized with LRTI (38.3%, n=257) were in the 0-3 months age group. Compared to other age groups, RSV positivity was highest in that age group for acute bronchiolitis (57%), pneumonia (39.5%) and also total children with LRTI (47.9%). RSV is a very important

    The aims of the study were to evaluate the incidence of Helicobacter pylori and Helicobacter heilmannii in untreated Bulgarian children from 1996 to 2006, to analyse the performance of diagnostic tests, and to look at H. pylori density in specimens by culture. Antral specimens from children with chronic gastritis (n=513), peptic ulcers (n=54) and other diseases (n=91) were evaluated by direct Gram staining (DGS), in-house rapid urease test (RUT) and culture. The living environment and semi-quantitative H. pylori density were assessed in 188 and 328 children, respectively. H. pylori infection was found in children with ulcers (77.8 %), chronic gastritis (64.5 %) and other diseases (36.3 %). Half (51.4 %) of patients aged 1-5 years and 77.4 % of those aged 16-17 years were H. pylori-positive. Of all children, 328 (49.8 %) showed positive DGS, 184 (28 %) had a positive RUT, and 386 (58.7 %) were culture-positive. Unlike gastric mucus specimens, frozen biopsy specimens provided reliable diagnosis. H. heilmannii was observed in two (0.3 %) children. High H. pylori density (growth into all quadrants of plates) was found in 18 % of 328 children evaluated, involving 31 % of ulcer and 16.7 % of non-ulcer patients. H. pylori infection was more common in rural children with chronic gastritis (91.3 %) than in the remainder (66.7 %). In conclusion, H. pylori infection was common in symptomatic Bulgarian children. The infection prevalence was >77 % in patients aged 16-17 years, in children with a duodenal ulcer, and in rural patients. H. heilmannii infection was uncommon. The performance of the bacterial culture was good. The impact of H. pylori density on the clinical expression and eradication of the infection requires further evaluation. The results highlight the need for routine H. pylori diagnosis in rural children with chronic gastritis.

    Impaired motor coordination is prevalent in children with Autism Spectrum Disorders (ASD) and affects adaptive skills. Little is known about the development of motor patterns in young children with ASD between 2 and 6 years of age. The purpose of the current study was threefold: (1) to describe developmental correlates of motor coordination in children with ASD, (2) to identify the extent to which motor coordination deficits are unique to ASD by using a control group of children with other developmental disabilities (DD), and (3) to determine the association between motor coordination variables and functional fine motor skills. Twenty-four children with ASD were compared to 30 children with typical development (TD) and 11 children with DD. A precision grip task was used to quantify and analyze motor coordination. The motor coordination variables were two temporal variables (grip to load force onset latency and time to peak grip force) and two force variables (grip force at onset of load force and peak grip force). Functional motor skills were assessed using the Fine Motor Age Equivalents of the Vineland Adaptive Behavior Scale and the Mullen Scales of Early Learning. Mixed regression models were used for all analyses. Children with ASD presented with significant motor coordination deficits only on the two temporal variables, and these variables differentiated children with ASD from the children with TD, but not from children with DD. Fine motor functional skills had no statistically significant associations with any of the motor coordination variables. These findings suggest that subtle problems in the timing of motor actions, possibly related to maturational delays in anticipatory feed-forward mechanisms, may underlie some motor deficits reported in children with ASD, but that these issues are not unique to this population. Further research is needed to investigate how children with ASD or DD compensate for motor control deficits to establish functional skills

    In this study, we evaluated the association between prenatal and postnatal exposure to environmental tobacco smoke and the development of insulin resistance in 10 year old children. Fasting blood samples were collected from 470 children participating in two prospective birth cohorts. Of those 276 were selected population based and enriched with 194 children exceeding the 85th percentile of body mass index in this age group. Children already having diabetes type 1 or 2 at the age of 10 years were excluded. Fasting blood insulin and glucose levels and calculated HOMA index for insulin resistance assessment were analysed using generalised additive models. Potential confounders were adjusted for. Insulin resistance was increased by 24% in children frequently exposed to environmental tobacco smoke during childhood (MR(adj) = 1.24, p = 0.001), while glucose levels were not. Exclusion of prenatally exposed children did not attenuate the association (MR(adj) = 1.25, p = 0.006). After stratification, the effect sizes were identical within overweight children and the population based sample of children. Insulin resistance and fasting insulin levels were increasing with increasing numbers of cigarettes smoked in children's home. Maternal smoking during the third trimester of pregnancy increased children's insulin levels (MR(adj) = 1.19, p = 0.037), and even more so, if children were exclusively breastfed after birth (MR(adj) = 1.31, p = 0.016). Increased mean ratios were found for smoking of a third person in addition to maternal smoking. Positive dose-dependent associations and independent effects of postnatal exposure suggest involvement of environmental tobacco smoke in the risk for development of insulin resistance in children.

    Abstract We use a representative sample of 2561 children 0–23 months old to identify the factors most significantly associated with child stunting in the state of Maharashtra, India. We find that 22.7% of children were stunted, with one‐third (7.4%) of the stunted children severely stunted. Multivariate regression analyses indicate that children born with low birthweight had a 2.5‐fold higher odds of being stunted [odds ratio (OR) 2.49; 95% confidence interval (CI) 1.96–3.27]; children 6–23 months old who were not fed a minimum number of times/day had a 63% higher odds of being stunted (OR 1.63; 95% CI 1.24–2.14); and lower consumption of eggs was associated with a two‐fold increased odds of stunting in children 6–23 months old (OR 2.07; 95% CI 1.19–3.61); children whose mother's height was < 145 cm, had two‐fold higher odds of being stunted (OR 2.04; 95% CI 1.46–2.81); lastly, children of households without access to improved sanitation had 88% higher odds of being severely stunted (OR 1.88; 95% CI 1.17–3.02). Attained linear growth (height‐for‐age z‐score) was significantly lower in children from households without access to improved sanitation, children of mothers without access to electronic media, without decision making power regarding food or whose height was < 145 cm, children born with a low birthweight and children 6–23 months old who were not fed dairy products, fruits and vegetables. In Maharashtra children's birthweight and feeding practices, women's nutrition and status and household sanitation and poverty are the most significant predictors of stunting and poor linear growth in children under 2 years. Key messages One in five (22.7%) of children 0–23 months old in the state of Maharashtra were stunted, and one‐third (7.4%) of the stunted children were severely stunted.Birthweight, child feeding, women's nutrition and household sanitation were the most significant predictors of stunting and poor

    Children have formal science instruction from kindergarten in Australia and from Year 3 in China. The purpose of this research was to explore the impact that different approaches to primary science curricula in China and Australia have on children's conceptual understanding of science. Participants were Year 3 children from three schools of high, medium and low socio-economic status in Hunan Province, central south China (n = 135) and three schools of similar socio-economic status in Western Australia (n = 120). The students' understanding was assessed by a science quiz, developed from past Trends in Mathematics and Science Study science released items for primary children. In-depth interviews were carried out to further explore children's conceptual understanding of living things, the Earth and floating and sinking. The results revealed that Year 3 children from schools of similar socio-economic status in the two countries had similar conceptual understandings of life science, earth science and physical science. Further, in both countries, the higher the socio-economic status of the school, the better the students performed on the science quiz and in interviews. Some idiosyncratic strengths and weaknesses were observed, for example, Chinese Year 3 children showed relative strength in classification of living things, and Australian Year 3 children demonstrated better understanding of floating and sinking, but children in both countries were weak in applying and reasoning with complex concepts in the domain of earth science. The results raise questions about the value of providing a science curriculum in early childhood if it does not make any difference to students' conceptual understanding of science.

    This study investigated whether parenting behaviors differed between parents of 68 clinically anxious children and 106 healthy control children aged 4-12 years. The effects of parent gender, child gender and child age on parenting were explored. Mothers and fathers completed a questionnaire to assess parenting behaviors in for children hypothetically anxious situations. Results showed that parents of clinically anxious children reported more anxiety-enhancing parenting (reinforcement of dependency and punishment) as well as more positive parenting (positive reinforcement). For the clinical sample, fathers reported using more modeling/reassurance than mothers, and parents reported using more force with their 4-7-year-olds than with their 8-12-year-olds. No interaction effects were found for child gender with child anxiety status on parenting. Results indicate that for intervention, it is important to measure parenting behaviors, and to take into account father and mother differences and the age of the child.

    In adults and older children, evidence consistent with relative separation between selective and sustained attention, superimposed upon generally positive inter-test correlations, has been reported. Here we examine whether this pattern is detectable in 5-year-old children from the healthy population. A new test battery (TEA-ChJ) was adapted from measures previously used with adults and older children and administered to 172 5-year-olds. Test-retest reliability was assessed in 60 children. Ninety-eight percent of the children managed to complete all measures. Discrimination of visual and auditory stimuli were good. In a factor analysis, the two TEA-ChJ selective attention tasks (one visual, one auditory) loaded onto a common factor and diverged from the two sustained attention tasks (one auditory, one motor), which shared a common loading on the second factor. This pattern, which suggests that the tests are indeed sensitive to underlying attentional capacities, was supported by the relationships between the TEA-ChJ factors and Test of Everyday Attention for Children subtests in the older children in the sample. It is possible to gain convincing performance-based estimates of attention at the age of 5 with the results reflecting a similar factor structure to that obtained in older children and adults. The results are discussed in light of contemporary models of attention function. Given the potential advantages of early intervention for attention difficulties, the findings are of clinical as well as theoretical interest. PMID:24376591

    The linguistic skills of 8-year-old children born preterm (n = 42) with birthweight < 1750 grams from a 1-year birth cohort for 1985-86 in northern Finland were studied with three different language tests, namely the Illinois Test of Psycholinguistic Abilities (ITPA), the Token Test for Children (TTC) and the Morphological Test (MT) for Finnish children. Full-term control children (n = 42) with birthweight > or = 2500 grams from the same birth cohort were matched individually with their preterm pairs for age, sex, twinship, mother's education, place of residence, birth order and family type. The preterm children's language abilities were studied in relation to their neurological status and to the periventricular leukomalacia (PVL) findings of magnetic resonance imaging (MRI). The preterm children with minor neurodevelopmental dysfunctions (MND) scored worst and differed significantly from their matched controls in TTC. They also differed significantly from other preterm subgroups, namely healthy preterm and preterm children with cerebral palsy (CP), in verbal comprehension measured by TTC. PVL findings were not associated with performance in the language ability tests. A closer and regular follow-up of language development in the MND-disabled group among the low-birthweight preterm children is recommended.

    Urinary 1-hydroxypyrene (1-OHP) is a biomarker of polycyclic aromatic hydrocarbon (PAH) exposure. We measured urinary 1-OHP in 48 children 3 years of age in Mariupol, Ukraine, who lived near a steel mill and coking facility and compared these with 1-OHP concentrations measured in 42 children of the same age living in the capital city of Kiev, Ukraine. Children living in Mariupol had significantly higher urinary 1-OHP and creatinine-adjusted urinary 1-OHP than did children living in Kiev (adjusted: 0.69 vs. 0.34 μmol/mol creatinine, p < 0.001; unadjusted: 0.42 vs. 0.30 ng/mL, p = 0.002). Combined, children in both cities exposed to environmental tobacco smoke in their homes had higher 1-OHP than did children not exposed (0.61 vs. 0.42 μmol/mol creatinine; p = 0.04; p = 0.07 after adjusting for city). In addition, no significant differences were seen with sex of the children. Our sample of children in Mariupol has the highest reported mean urinary 1-OHP concentrations in children studied to date, most likely due to their proximity to a large industrial point source of PAHs.

    Children with visual defects who took part in a 10-year survey were compared with their peers on measures of intelligence, reading, mathematics and sporting ability. Results are consistent with earlier findings of increased intelligence among children with myopia and slightly reduced intelligence among children with amblyopia. Those with other visual defects had normal intelligence scores. Once intelligence had been taken into account, only children with mild hypermetropia were under-achieving at reading. Those with severe myopia were reading better than expected. None of the children could be shown to be over- or under-achieving at maths, any variation being due to intelligence. The mothers of children with visual defects perceived them to be less able at sport. Comparison of the performances of children with minor visual defects who had and had not been prescribed spectacles did not suggest any disadvantage for those without spectacles, with the possible exception of children with mild hypermetropia. It is concluded that the majority of visual defects do not affect children's learning, and that current indications for prescribing spectacles need to be validated.

    This study aimed to investigate obstacle crossing in 7-9-year-old children with Down syndrome (DS). Fifteen children with DS, age- and gender-matched with 15 typically developing (TD) children, were recruited to walk and cross obstacles with heights of 10%, 20% and 30% of their leg lengths. End-point and kinematic variables of obstacle crossing were obtained using a three-dimensional motion analysis system. The results showed that children with DS tend to adopt a lower speed and larger step width when they perceive instability. Moreover, unlike TD children, children with DS adopt a pelvic strategy (i.e., greater pelvic leading-side listing and forward rotation) to achieve a higher leading toe clearance with a longer step length, presumably for safety reasons. This pelvic strategy increased the frontal plane motion of the whole leg and trunk, and thus possibly stability, during obstacle crossing. However, this strategy may be inefficient. Trailing toe clearance did not differ significantly between two groups. The results of this study suggest that children with DS tend to use inefficient and conservative strategies for obstacle crossing. Knowledge of both end-point and kinematic control of obstacle crossing in children with DS is useful for understanding the mechanisms of obstacle-related falls. Moreover, obstacle crossing can be used as a task-oriented rehabilitation program for children with DS.

    Objectives To determine the prevalence of Dravet syndrome, an epileptic encephalopathy caused by SCN1A-mutations, often with seizure onset after vaccination, among infants reported with seizures following vaccination. To determine differences in characteristics of reported seizures after vaccination in children with and without SCN1A-related Dravet syndrome. Methods Data were reviewed of 1,269 children with seizures following immunization in the first two years of life, reported to the safety surveillance system of the Dutch national immunization program between 1 January 1997 and 31 December 2006. Selective, prospective follow-up was performed of children with clinical characteristics compatible with a diagnosis of Dravet syndrome. Results In 21.9% (n = 279) of children, a diagnosis of Dravet syndrome could not be excluded based on available clinical data (median age at follow-up 16 months). Additional follow-up data were obtained in 83.9% (n = 234) of these children (median age 8.5 years). 15 (1.2% of 1,269; 95%CI:0.6 to 1.8%) children were diagnosed with SCN1A-related Dravet syndrome. Of all reported seizures following vaccinations in the first year of life, 2.5% (95%CI:1.3 to 3.6%) were due to SCN1A-related Dravet syndrome, as were 5.9% of reported seizures (95%CI:3.1 to 8.7%) after 2nd or 3rd DTP-IPV-Hib vaccination. Seizures in children with SCN1A-related Dravet syndrome occurred more often with a body temperature below 38.5°C (57.9% vs. 32.6%, p = 0.020) and reoccurred more often after following vaccinations (26.7% vs. 4.0%, p = 0.003), than in children without a diagnosis of SCN1A-related Dravet Syndrome. Conclusions Although Dravet syndrome is a rare genetic epilepsy syndrome, 2.5% of reported seizures following vaccinations in the first year of life in our cohort occurred in children with this disorder. Knowledge on the specific characteristics of vaccination-related seizures in this syndrome might promote early diagnosis and indirectly

    Levy, M; Balfe, J W; Geary, D F; Fryer-Keene, S P; Bannatyne, R M

    The clinical aspects of peritonitis were reviewed in 83 patients treated with continuous ambulatory or continuous cyclic peritoneal dialysis between May 1978 and April 1988. Peritonitis occurred in 50 patients whose mean duration of dialysis was 17.8 months, but not in 33 patients with a mean duration of dialysis of 10.4 months. The mean time from starting dialysis to the first episode of peritonitis was 7.1 months. The peritonitis rate was lower for continuous cyclic than for continuous ambulatory peritoneal dialysis (1 episode per 12.9 vs. 1 episode per 8.1 patient months, respectively). In 39% of the episodes, gram stain of the dialysate was positive. The dialysate leukocyte count was higher in gram-negative than in gram-positive peritonitis. Seventy percent of the peritonitis episodes were gram positive, and Staphylococcus aureus was predominant. Only 1 of the 7 diapered infants had gram-negative organisms associated with peritonitis. Catheters were replaced in 48 cases, 26 because of infection. Sixty-nine percent of the patients were cured with antibiotic therapy alone. Although peritonitis was associated with a mortality rate of 1.2%, peritoneal dialysis remains the favored dialytic mode for children.

    The aim of the study was to develop a newly devised child observation sheet (COS-5) as a scoring sheet, based on the Childhood Autism Rating Scale (CARS), for use in the developmental evaluation of 5-year-old children, especially focusing on children with autistic features, and to verify its validity. Seventy-six children were studied. The children were recruited among participants of the Japan Children's Cohort Study, a research program implemented by the Research Institute of Science and Technology for Society (RISTEX) from 2004 to 2009. The developmental evaluation procedure was performed by doctors, clinical psychologists, and public health nurses. The COS-5 was also partly based on the Kyoto Scale of Psychological Development 2001 (Kyoto Scale 2001). Further, the Developmental Disorders Screening Questionnaire for 5-Years-Olds, PDD-Autism Society Japan Rating Scale (PARS), doctor interview questions and neurological examination for 5-year-old children, and the Draw-a-Man Test (DAM) were used as evaluation scales. Eighteen (25.4%) children were rated as Suspected, including Suspected PDD, Suspected ADHD and Suspected MR. The COS-5 was suggested to be valid with favorable reliability (α=0.89) and correlation with other evaluation scales. The COS-5 may be useful, with the following advantages: it can be performed within a shorter time frame; it facilitates the maintenance of observation quality; it facilitates sharing information with other professions; and it is reliable to identify the autistic features of 5-year-old children. In order to verify its wider applications including the screening of infants (18months to 3years old) by adjusting the items of younger age, additional study is needed.

    2011-01-01

    OBJECTIVE: To examine the associations between depression in fathers of 1-year-old children and specific positive and negative parenting behaviors discussed by pediatric providers at well-child visits. METHODS: We performed a cross-sectional secondary analysis by using interview data from 1746 fathers of 1-year-old children in the Fragile Families and Child Wellbeing Study. Positive parenting behaviors included fathers' reports of playing games, singing songs, and reading stories to their children ≥3 days in a typical week. Negative parenting behavior included fathers' reports of spanking their 1-year-old children in the previous month. Depression was assessed by using the World Health Organization Composite International Diagnostic Interview Short Form. Weighted bivariate and multivariate analyses of parenting behaviors were performed while controlling for demographics and paternal substance abuse. RESULTS: Overall, 7% of fathers had depression. In bivariate analyses, depressed fathers were more likely than nondepressed fathers to report spanking their 1-year-old children in the previous month (41% compared with 13%; P < .01). In multivariate analyses, depressed fathers were less likely to report reading to their children ≥3 days in a typical week (adjusted odds ratio: 0.38 [95% confidence interval: 0.15–0.98]) and much more likely to report spanking (adjusted odds ratio: 3.92 [95% confidence interval: 1.23–12.5]). Seventy-seven percent of depressed fathers reported talking to their children's doctor in the previous year. CONCLUSIONS: Paternal depression is associated with parenting behaviors relevant to well-child visits. Pediatric providers should consider screening fathers for depression, discussing specific parenting behaviors (eg, reading to children and appropriate discipline), and referring for treatment if appropriate.

    It is generally believed that infants are more susceptible to development of renal scarring after pyelonephritis than children over 5 years old. This view has led to differences in investigations and treatment according to age. The aim of this prospective study was to assess the occurrence of renal parenchymal lesion in children over 5 years admitted with a first-time symptomatic urinary tract infection (UTI). Between October 2000 and April 2002, 52 children aged over 5 years who were admitted to our department with probable acute pyelonephritis (APN) and a positive urine culture were included in this study. All children received antibiotics for 14 days. During the acute phase of infection, scintigraphy with technetium-99m-labeled dimercaptosuccinic acid (DMSA) and ultrasonography (US) were done. Voiding cystourethrography (VCUG) was performed in all children early in the course of the illness, generally within 5-7 days of hospitalization. When scintigraphy showed renal parenchymal changes, repeat scintigraphy was done after at least 3 months to assess the progression of renal abnormalities. Of the 52 children with a first-time documented pyelonephritis, cortical scintigraphy showed renal lesion in 41 children (78.8%). US was normal in all children with normal renal scintigraphy, while it detected renal abnormalities in 16 of the 41 (39 %) with abnormal scintigraphy (p <0.0001). Topographic analysis of the 165 focal lesions showed that 42.4% were localized to the upper poles, 17.5% to the middle third, and 40% to the lower poles of the kidneys. Repeat scintigraphy showed persistent lesions corresponding to those on the initial scan in nine (28.2%) of the 32 children. Renal lesions had partly regressed in 23 (71.8%) of the patients who underwent repeat scintigraphy. Vesicoureteral reflux was observed in 13.4% of kidneys and renal parenchymal abnormalities were identified in 71.4% and 72.2% of renal units, respectively, with and without reflux ( p >0.05). In

    2002-01-01

    This article presents the findings of the final phase of a 5-year longitudinal study with 168 middle- and upper middle-class children in which the complex relations among early home literacy experiences, subsequent receptive language and emergent literacy skills, and reading achievement were examined. Results showed that children's exposure to books was related to the development of vocabulary and listening comprehension skills, and that these language skills were directly related to children's reading in grade 3. In contrast, parent involvement in teaching children about reading and writing words was related to the development of early literacy skills. Early literacy skills directly predicted word reading at the end of grade 1 and indirectly predicted reading in grade 3. Word reading at the end of grade 1 predicted reading comprehension in grade 3. Thus, the various pathways that lead to fluent reading have their roots in different aspects of children's early experiences.

    Jack, Fiona; Simcock, Gabrielle; Hayne, Harlene

    2012-01-01

    This report describes the first prospective study specifically designed to assess children's verbal memory for a unique event 6 years after it occurred. Forty-six 27- to 51-month-old children took part in a unique event and were interviewed about it twice, after 24-hr and 6-year delays. During the 6-year interview, 9 children verbally recalled the event, including 2 who were under 3 years old when the event occurred. This may be the most convincing evidence to date that such early experiences can be verbally recalled after long delays. These data have important implications for current theories of memory development and childhood amnesia and underscore some of the problems associated with evaluating the veracity of early memories under less controlled conditions.

    The increasing prevalence of childhood overweight and obesity has been associated with an increased risk for cardiovascular disease (CVD). While several studies examined the effect of single behaviors such as physical activity (PA), sedentary behavior or diet on CVD risk, there is a lack of research on combined associations, specifically in children. Therefore, the purpose of this study was to examine the joint association of PA or screen time (ST) and diet on CVD risk factors in children. PA, STand diet were assessed via questionnaire in 210 fifth grade students (age: 10.6 ± 0.4 years). The healthy eating index (HEI) was subsequently calculated as indicator for diet quality. Height, weight, % body fat, and resting blood pressure were measured according to standard procedures and blood samples obtained via fingerprick were assayed for blood lipids. Total cholesterol HDL ratio (TC:HDL), mean arterial pressure (MAP), and % body fat were used as indicators of CVD risk. 55% of children did not meet current PA recommendations on at least 5 days/week and 70% exceeded current recommendations for ST. Further, only 2.5% possessed a "good" diet (HEI> 80). There was no significant association of PA or STand diet on CVD risk score. Neither TC:HDL, MAP, and % body fat nor the total CVD risk score was significantly correlated with diet, PA, or ST. Children in the high PA group, however, had significantly better diet scores. Despite the fact that self-reported PA, ST, or dietary intake were not directly related to CVD risk in this sample, higher activity levels were associated with a healthier diet and lower ST indicating an overall healthier lifestyle of this subgroup.

  13. Varicella vaccination coverage of children under two years of age in Germany

    PubMed Central

    2010-01-01

    Background Since July 2004, routine varicella vaccination is recommended by the German Standing Vaccination Committee in Germany. Health Insurance Funds started to cover vaccination costs at different time points between 2004 and 2006 in the Federal States. Nationwide representative data on vaccination coverage against varicella of children under two years of age are not available. We aimed to determine varicella vaccination coverage in statutory health insured children under two years of age in twelve German Federal States using data from associations of statutory health insurance physicians (ASHIPs), in order to investigate the acceptance of the recommended routine varicella vaccination programme. Methods We analysed data on varicella vaccination from 13 of 17 ASHIPs of the years 2004 to 2007. The study population consisted of all statutory health insured children under two years of age born in 2004 (cohort 2004) or 2005 (cohort 2005) in one of the studied regions. Vaccination coverage was determined by the number of children vaccinated under 2 years of age within the study population. Results Varicella vaccination coverage of children under two years of age with either one dose of the monovalent varicella vaccine or two doses of the measles, mumps, rubella, and varicella vaccine increased from 34% (cohort 2004) to 51% (cohort 2005) in the studied regions (p < 0.001). More than half of the vaccinated children of cohort 2004 and two third of cohort 2005 were immunised at the recommended age 11 to 14 months. The level of vaccination coverage of cohort 2004 was significantly associated with the delay in introduction of cost coverage since the recommendation of varicella vaccination (p < 0.001). Conclusions Our study shows increasing varicella vaccination coverage of young children, indicating a growing acceptance of the routine varicella vaccination programme by the parents and physicians. We recommend further monitoring of vaccination coverage using data from

    2016-12-05

    To track the course of development in children's fine-grained perception of Mandarin tones, the present study explored how categorical perception (CP) of Mandarin tones emerges along age among 70 four- to seven-year-old children and 16 adults. Prominent discrimination peaks were found for both the child and the adult groups, and they were well aligned with the corresponding identification crossovers. Moreover, six-year-olds showed a much narrower width (i.e. a sharper slope) compared to younger children, and have already acquired adult-like identification competence of Mandarin high-level and mid-rising tones. Although the ability to discriminate within-category tone pairs did not change, the between-category discrimination accuracies were positively correlated with chronological ages among child participants. We assume that the perceptual refinement of Mandarin tones in young children may be driven by an accumulation of perceptual development from the tonal information of the ambient sound input.

    The number of studies on patch-test results in children and adolescents has gradually increased in recent years, thus stimulating reviews. This paper is a systematic review of a 15-year period devoted to studying the issue. Variations pertaining to the number and age groups of tested children and/or adolescents, the number of subjects with atopy/atopic dermatitis history, the quantity, type and concentrations of the tested substances, the test technique and type of data regarding clinical relevance, must all be considered in evaluating these studies, as they make it harder to formulate conclusions. The most common allergens in children were nickel, thimerosal, cobalt, fragrance, lanolin and neomycin. In adolescents, they were nickel, thimerosal, cobalt, fragrance, potassium dichromate, and Myroxylon pereirae. Knowledge of this matter aids health professionals in planning preventive programs aimed at improving children's quality of life and ensuring that their future prospects are not undermined.

    2003-01-01

    Learning to use symbols is a challenge for young children even when the symbol in question (e.g., a live video image) is iconic and seems transparent to adults. This research examined the effect of experience on children's use of video-presented information. Two-year-old children saw themselves "live" on their family television for 2 weeks and then participated in an object-retrieval task. The children reliably used a live video presentation of an adult hiding a toy in an adjoining room to find the toy. Most also transferred what they learned to a task involving another symbol (pictures) that typically is very difficult for this age group. The results reveal flexibility in 2-year-olds' symbol use that follows from successful representation of a symbolic relation.

    2011-09-01

    Evidence from recent meta-analytic and narrative review suggests that early intensive behavioral intervention (EIBI) may improve life chances of preschool children with autism. Unfortunately, there are few data indicating whether early gains are maintained after intervention ceases. The purpose of the present study was to establish the 2-year follow-up outcome for children with autism (N = 41) who had participated in an earlier 2-year controlled comparison of EIBI. Twenty-three children in the intervention group (100% of original sample) and 18 in the treatment-as-usual comparison group (86% of original sample) were located and retested. Group differences favoring intervention substantially diluted in this period but varied significantly between subgroups who had received university-supervised and parent-commissioned interventions, favoring the latter. These groups differed in terms of their baseline characteristics and intensity of intervention. Results strongly suggest a need for better characterization of those children who would benefit from more active maintenance programs.

Objective To assess the influence of sex, age and body mass index (BMI) on the CIMT in healthy children and adolescents aged 1 to 15 years. Methods A total of 280 healthy children and adolescents (males, n=175; mean age, 7.49±3.57 years; mean BMI, 17.94±4.1 kg/m2) were screened for CIMT assessment. They were divided into 3 groups according to age: GI, 1 to 5 years [n=93 (33.2%); males, 57; mean BMI, 16±3 kg/m2]; GII, 6 to 10 years [n=127 (45.4%); males, 78; mean BMI, 17.9±3.7 kg/m2], and GIII, 11 to 15 years [n=60 (21.4%); males, 40; mean BMI, 20.9±4.5 kg/m2]. Results There was no significant difference in CIMT values between male and female children and adolescents (0.43±0.06 mm vs. 0.42±0.05 mm, respectively; p=0.243). CIMT correlated with BMI neither in the total population nor in the 3 age groups according to Pearson correlation coefficient. Subjects aged 11 to 15 years had the highest CIMT values (GI vs. GII, p=0.615; GI vs. GIII, p=0.02; GII vs. GIII, p=0.004). Conclusions CIMT is constant in healthy children younger than 10 years, regardless of sex or BMI. CIMT increases after the age of 10 years. PMID:26959401

    Preservation and loss to forgetting of autobiographical memories is a focus in both the adult and developmental literatures. In both, there are comparative arguments regarding rates of forgetting. Children are assumed to forget autobiographical memories more rapidly than adults, and younger children are assumed to forget more rapidly than older children. Yet few studies can directly inform these comparisons: few feature children and adults, and few prospectively track the survival of specific autobiographical memories over time. In a 4-year prospective study, we obtained autobiographical memories from children 4, 6, and 8 years, and adults. We tested recall of different subsets of the events after 1, 2, and 3 years. Accelerated rates of forgetting were apparent among all child groups relative to adults; within the child groups, 4- and 6-year-olds had accelerated forgetting relative to 8-year-olds. The differences were especially pronounced in open-ended recall. The thematic coherence of initial memory reports also was a significant predictor of the survival of specific memories. The pattern of findings is consistent with suggestions that the adult distribution of autobiographical memories is achieved as the quality of memory traces increases (here measured by thematic coherence) and the rate of forgetting decreases.

    This study was conducted among two groups of 105 children in a hospital in Yaoundé, Cameroon, to determine the causes of anaemia in children aged 5- 10-years-old. The study group included children presenting clinical evidence of anaemia while the control group was made of children without anaemia. Both sets of children were matched for neighbourhoods within the city of Yaoundé. Each child had a complete physical examination, full blood count, haemoglobin electrophoresis, reticulocyte counts, and stool samples examined for parasites and hemoparasites. The mean haemoglobin level was 7.77 +/- 1.54 g/dL in the study group and 12.37 +/- 1.23 in the control group. The anaemia was mainly normocytic, normochromic and regenerative in the study group, usually associated with evidence of haemolysis. Patients with homozygous sickle cell disease were found only in the study group (n = 13; 12.3%). Malaria parasites were noted in 89 children (84.7%) in the study group, compared with 34 (32.4%) in the control group (p = 0.0004). Prevalence of intestinal parasites was similar in both groups (50.8%). Protein-calorie malnutrition was rare and was not associated with anemia. We conclude that both malaria and sickle cell anaemia play an important role in anaemia in children aged 5-10 years.

    Nutritional status of children is a global indicator of children's well-being and, indirectly, of the community's well-being. The first objective of this work is to assess the nutritional status of children under five years-old living in a suburb of the city of Lubumbashi, DR Congo, at the end of the 1998-2003 armed conflict. The second objective aims to identify some predictors of malnutrition. A multivariate logistic regression was applied to the results of a cross-sectional survey of 1963 children from selected households. In addition to the anthropometric variables, living conditions were also used. We observed 33.5% stunted growth and 3.8% emaciation. After logistic regression, a low maternal educational level (less than 7 years), the absence of a drinking water tap available in the house or yard, male gender, and age of children ( > 11 months) were all significantly associated with increased risk of stunted growth. Moreover, decreased appetite, diarrhea and age of children ( < 12 months) were significant predictors of emaciation. Compared to the classification of the World Health Organization, our results indicate that the prevalence of stunting is high and the prevalence of emaciation is low. Interventions against malnutrition should consider the various predictors discussed in this study in order to reduce mortality and morbidity in children and contribute to their well-being.

    In 2102, a multidiscplinary guideline was developed on behalf of the Dutch Association of Pediatrics entitled 'Gastroesophageal reflux disease in children from 0-18 years'. The North American Society for Pediatric Gastroenterology, Hepatology and Nutrition (NASPGHAN) and the European Society for Paediatric Gastroenterology, Hepatology and Nutrition (ESPGHAN) guideline from 2009 served for guidance. History and physical examination are usually sufficient for diagnosing gastroesophageal reflux disease. It is important to make a distinction between gastroesophageal reflux, a physiological phenomenon in children, and gastroesophageal reflux disease. In practice, medications are provided too often, especially in infants. Only children suffering from gastroesophageal reflux disease should be treated according to the therapeutical action plan.

    AIM: To review gastrointestinal and liver infections in children undergoing antineoplastic chemotherapy. To look at gut microflora features in oncology children. METHODS: We selected studies published after year 2000, excluding trials on transplanted pediatric patients. We searched English language publications in MEDLINE using the keywords: “gastrointestinal infection AND antineoplastic chemotherapy AND children”, “gastrointestinal infection AND oncology AND children”, “liver infection AND antineoplastic chemotherapy AND children”, “liver abscess AND chemotherapy AND child”, “neutropenic enterocolitis AND chemotherapy AND children”, “thyphlitis AND chemotherapy AND children”, “infectious diarrhea AND children AND oncology”, “abdominal pain AND infection AND children AND oncology”, “perianal sepsis AND children AND oncology”, “colonic pseudo-obstruction AND oncology AND child AND chemotherapy”, “microflora AND children AND malignancy”, “microbiota AND children AND malignancy”, “fungal flora AND children AND malignancy”. We also analysed evidence from several articles and book references. RESULTS: Gastrointestinal and liver infections represent a major cause of morbidity and mortality in children undergoing antineoplastic chemotherapy. Antineoplastic drugs cause immunosuppression in addition to direct toxicity, predisposing to infections, although the specific risk is variable according to disease and host features. Common pathogens potentially induce severe diseases whereas opportunistic microorganisms may attack vulnerable hosts. Clinical manifestations can be subtle and not specific. In addition, several conditions are rare and diagnostic process and treatments are not standardized. Diagnosis may be challenging, however early diagnosis is needed for quick and appropriate interventions. Interestingly, the source of infection in those children can be exogenous or endogenous. Indeed, mucosal damage may allow the

    Malnutrition is one of the major causes of mortality and morbidity in children. Not only include acute effects on children's health, but also it has long-term effects on their cognitive development and economic growth in the society. Wasting (weight for height with Z<-1) is one of the malnutrition indices in children. The aim of this study was to determine the effect of a cooked meal for 175 days on the anthropometric indices of weight, height and weight for height (wasting) of 3-6 years old children in all the rural nursery of Qazvin province, in Iran. In this interventional study, 2385 children (48.8% female and 51.2% male) were recruited. Data were collected by a census in 2010. The children were received a cooked meal based on 360 +/- 20 kcal energy, 17% protein, 53% carbohydrate and 30% fat per day for 175 days at lunch time. The anthropometric indices were collected before and after the intervention. The results were analyzed using paired t-test by SPSS V.16 software. Prevalence of wasting (mild and moderate) and (sever malnutrition) after intervention reduced from 14.2 and 0.95-12.6 and 0.5%, respectively (p < 0.05). Receiving a cooked meal significantly decreased wasting (15.2-13.2%) in all children (p < 0.05). Nutritional intervention with cooked meal for 175 days had significant reduction in wasting in all children.

    Anemia in children under 5 years of age, defined by the World Health Organization as a hemoglobin concentration < 11 g/dL, is a global public health problem. According to the 2006 Demographic Health Survey, the prevalence of anemia among children under five in Uganda was 72% in 2006. The 2009 Uganda Malaria Indicator Survey was conducted in late 2009 and revealed that over 60% of children less than 5 years of age were anemic and that over half of children tested positive for malaria via a rapid diagnostic test. Children with concomitant malaria infection, and in households without any type of mosquito net were more likely to be anemic, confirming that children under 5 years, are vulnerable to both the threat of malaria and anemia and the beneficial effect of malaria prevention tools. However, prevention and treatment of other factors associated with the etiology of anemia (e.g., iron deficiency) are likely necessary to combat the toll of anemia in Uganda. PMID:26055748

    OBJECTIVE: To determine the prevalence of vitamin A deficiency in children aged 6-9 years in northern Ethiopia. METHODS: A cross-sectional study was carried out and the data were analysed for 824 (61.5%) of 1339 eligible children for whom there was complete information on biochemical vitamin A status, dietary vitamin A intake, ocular examination for xerophthalmia, and anthropometry. FINDINGS: The prevalence of xerophthalmia was 5.8%; serum retinol levels were below 0.35 mumol/l and between 0.35 and 0.70 mumol/l in 8.4% and 51.1% of the children respectively. The liver vitamin A reserve (modified relative dose response ratio > or = 0.06) was low in 41.0% of the children. CONCLUSION: The high prevalence of severe vitamin A deficiency in children aged 6-9 years indicates the need to reevaluate the practice of targeting vitamin A supplementation programmes on children under 6 years of age in areas where vitamin A deficiency is endemic.

    Childhood overweight and obesity, a worldwide problem, is generally identified using BMI (body mass index). However, this application of BMI has been little investigated in children below 5 years of age due to a lack of appropriate methods to assess body composition. Therefore, we used air displacement plethysmography (ADP) to study 4.4-year old boys and girls since this method is accurate in young children if they accept the requirements of the measurement. The purpose was to analyze the relationship between BMI and body fat in these children. Body composition was assessed in 76 (43 boys, 33 girls) of the 84 children brought to the measurement session. Boys and girls contained 25.2 ± 4.7 and 26.8 ± 4.0% body fat, respectively. BMI-based cut-offs for overweight could not effectively identify children with a high body fat content. There was a significant (P < 0.001) but weak (r = 0.39) correlation between BMI and body fat (%). In conclusion, requirements associated with a successful assessment of body composition by means of ADP were accepted by most 4-year-olds. Furthermore, BMI-based cut-offs for overweight did not effectively identify children with a high body fatness and BMI explained only a small proportion of the variation in body fat (%) in this age group.

    Our goal was to describe childhood cancer incidence and survival in Israel and to identify demographic and epidemiologic variations among children and adolescents with cancer. We used data from the Israel National Cancer Registry to examine the incidence and survival of pediatric cancer in Israeli children aged 0 to 19 years, diagnosed during the years 1998 to 2007. Cases were analyzed according to sex, age, ethnicity, and geographic region. Among the 4255 cases of childhood cancer, there was a total age-adjusted incidence rate of 172.4 per million for children aged 0 to 19 years and 153.4 per million for children aged 0 to 14 years. The incidence rate for boys was higher than for girls (192.5 and 153.3, respectively) and higher for Jewish children than for Arab children (177.6 and 156.8, respectively). The largest groups were leukemias (22%), lymphomas (20.2%), and central nervous system tumors (17.4%). The number of new cases increased each year, but the incidence rate remained steady. The survival probability updated to December 2008 was estimated and the 5-year survival was calculated for the new cases until the end of 2003. The overall survival at 5 years was 80.8%, with 72.8% for the Arabic population and 83.2% for the Jewish population, and depended on the diagnosis. Incidence and survival in childhood cancer in Israel is at the same medium level compared with other parts of the world. This study may set the basis for investigating the genetic and environmental factors that cause pediatric cancer in Israel, delineating the genetic basis for ethnic origin disparities in survival.

    Episodic memories for autobiographical events that happen in unique spatiotemporal contexts are central to defining who we are. Yet, before 2 years of age, children are unable to form or store episodic memories for recall later in life, a phenomenon known as infantile amnesia. Here, we studied the development of allocentric spatial memory, a fundamental component of episodic memory, in two versions of a real-world memory task requiring 18 month- to 5-year-old children to search for rewards hidden beneath cups distributed in an open-field arena. Whereas children 25-42-months-old were not capable of discriminating three reward locations among 18 possible locations in absence of local cues marking these locations, children older than 43 months found the reward locations reliably. These results support previous findings suggesting that allocentric spatial memory, if present, is only rudimentary in children under 3.5 years of age. However, when tested with only one reward location among four possible locations, children 25-39-months-old found the reward reliably in absence of local cues, whereas 18-23-month-olds did not. Our findings thus show that the ability to form a basic allocentric representation of the environment is present by 2 years of age, and its emergence coincides temporally with the offset of infantile amnesia. However, the ability of children to distinguish and remember closely related spatial locations improves from 2 to 3.5 years of age, a developmental period marked by persistent deficits in long-term episodic memory known as childhood amnesia. These findings support the hypothesis that the differential maturation of distinct hippocampal circuits contributes to the emergence of specific memory processes during early childhood.

    An intervention group (n=23) of preschool children with autism was identified on the basis of parent preference for early intensive behavioral intervention and a comparison group (n=21) identified as receiving treatment as usual. Prospective assessment was undertaken before treatment, after 1 year of treatment, and again after 2 years. Groups did not differ on assessments at baseline but after 2 years, robust differences favoring intensive behavioral intervention were observed on measures of intelligence, language, daily living skills, positive social behavior, and a statistical measure of best outcome for individual children. Measures of parental well-being, obtained at the same three time points, produced no evidence that behavioral intervention created increased problems for either mothers or fathers of children receiving it.

    2,5-Diketopiperazines (2,5-DKPs) are an important category of structurally diverse cyclic dipeptides with prominent biological properties. These 2,5-DKPs have been obtained from a variety of natural resources, including marine organisms. Because of the increasing numbers and biological importance of these compounds, this review covers 90 marine originated 2,5-DKPs that were reported from 2009 to the first half-year of 2014. The review will focus on the structure characterizations, biological properties and proposed biosynthetic processes of these compounds. PMID:25532564

    Data from National Health and Nutrition Examination Survey for the years 2011-2012 were used to evaluate variability in the observed levels of 20 urinary metabolites of volatile organic compounds (VOCs) by age, gender, and race/ethnicity among children aged 6-11 years. Exposure to environmental tobacco smoke was positively associated with the levels of selected metabolites of acrylonitrile, 1,3-butadiene, cyanide, and propylene oxide in a dose-response manner. Levels of the selected metabolites of acrolein, acrylonitrile, 1,3-butadiene, styrene, toluene, and xylene decreased with increase in age. Levels of 1-bromopropane decreased with number of rooms in the house but the reverse was true for 1,3-butadiene, carbon-disulfide, and N,N-dimethylformamide. Levels of most of the 20 metabolites did not vary with gender. Non-Hispanic white children had higher adjusted levels of N-Acetyl-S-(3,4-dihydroxybutyl)-L-cysteine (DHBMA), N-Acetyl-S-(N-methylcarbamoyl)-L-cysteine (AMCC), and phenylglyoxylic acid (PGA) than non-Hispanic black children. Non-Hispanic white children had statistically significantly higher adjusted levels of N-Acetyl-S-(2-carbamoyl-2-hydroxyethyl)-L-cysteine (GAMA), trans, trans-Muconic acid (MU), and N-Acetyl-S-(N-methylcarbamoyl)-L-cysteine (AMCC) than non-Hispanic Asian children but statistically significantly lower levels of N-Acetyl-S-(n-propyl)-L-cysteine (BPMA) than non-Hispanic Asian children. Non-Hispanic Asian children had the lowest levels of 13 of the 20 metabolites among four major racial/ethnic groups but highest levels for three metabolites. For selected metabolites of acrolein, acrylamide, acrylonitrile-vinyl chloride-ethylene oxide, benzene, 1,3-butadien, crotonaldehyde, cyanide, ethylbenzene-styrene, and toluene, children had statistically significantly higher levels than nonsmoking adults. These results demonstrate how vulnerable children are to being exposed to harmful chemicals like VOCs in their own homes.

    Summary Background Atherosclerosis is a chronic inflammatory disease which starts early in life and depends on many factors, an important one being dyslipoproteinemia. According to several studies, atherosclerotic plaques or their precursors could be seen in children younger than 10 years. During later life, interaction with a sedentary way of life, as well as unhealthy nutrition, smoking, alcohol consumption, obesity and family history of cardiovascular disease cause the burden of atherosclerotic disease. Methods Study included 624 children (316 boys, 308 girls), aged from 7–13 years. We analysed socio-demographic data (BMI, blood pressure, cardiovascular family history, smoking status), as well as lipid status with lipoprotein little a-Lp(a), and apolipoproteins: Apo AI, Apo B-100 for all children. This enabled us to calculate new atherogenic indices Tg/HDL-c, lipid tetrad index (LTI) and lipid pentad index (LPI). Cardiovascular risk for later life was estimated by using modified Risk Score for Young Individuals (RS), which divided the subjects according to the score level: low, medium and higher risk. Results The older children (13 y) had better lipid status than the younger children, i.e. significantly lower total cholesterol, LDL-C, triglycerides and non-HDL-C concentration and significantly higher HDL-C concentration than the younger children and this was in accordance with the RS level. Children with a positive family history of CV disease had significantly higher Lp(a) concentration and blood pressure. LPI was significantly higher in children with a higher RS. Conclusions The results of our work could be used for cardiovascular risk assessment in apparently healthy children to provide preventive measures which could control the changeable risk factors.

    This study investigates marijuana exposures among children <6 years old in the United States using data from the National Poison Data System. From 2000 through 2013, there were 1969 marijuana exposures among children <6 years old and an exposure rate of 5.90 per million children. The mean age of an exposed child was 1.81 years (median = 1.58 years). The majority of the children were exposed through ingestion (75.0%), and 18.5% of exposures required admission to a health care facility. The rate of marijuana exposure was significantly (2.82 times) higher in states where its use was legalized prior to 2000 compared with states where its use is not legal. Because more states are likely to pass legislation legalizing medical and recreational use of marijuana, increased efforts to establish child-focused safety requirements regarding packaging of commercially sold marijuana products are needed to help prevent more children from being exposed to this schedule I substance.

    Normative data on skills of the tongue used in eating are presented. Normal children 2 to 5 years old were studied regarding their preference of placing food either on the right or left side when eating, and they were compared with age-matched Down's syndrome children. In addition, the ability to move food from the right to the left side of the mouth was studied. Normal children underwent a transition from predominantly placing food on the right side at 2 years of age to predominantly placing it on the left side at 4 years of age. Among Down's syndrome children females preferred the right side, and males preferred the left side. The ability to move food from right to left (lateralizing) undergoes a developmental progression from tilting the head to rolling, followed by slow and eventually by smooth movement from one side to the other. Only 15% of the 5-year-olds were able to move food smoothly from side to side. These data provide a baseline against which children with eating problems can be compared.

    Children born very preterm are at greater risk of ophthalmic morbidities, including strabismus, than children born at term. We evaluated perinatal factors associated with strabismus at age 2 years in a large population of infants delivered before 28 weeks’ gestation. A total of 996 infants in the multicenter ELGAN (Extremely Low Gestational Age Newborn) study who had a retinal exam in infancy and a developmental assessment at 2 years corrected age are included. Their mothers were interviewed about the pregnancy, and both mother and newborn charts were reviewed. Certified examiners administered the Bayley Scales of Infant Development-II and performed an examination of ocular alignment. Time-oriented logistic regression risk models were created to evaluate the associations of characteristics and exposures with the development of strabismus. Overall, 14% (n = 141) of the children had strabismus at 2 years, and 80% of strabismic children had esotropia. Characteristics associated with strabismus were birth before 26 weeks’ gestation, severe fetal growth restriction, and maternal history of aspirin ingestion. Associated postnatal factors included a SNAP-II (Score for Neonatal Acute Physiology) illness severity value ≥30, brain ventriculomegaly, type I retinopathy of prematurity, and ventilator-dependent severe bronchopulmonary dysplasia. Strabismus in very preterm populations is associated with a number of antenatal and postnatal antecedents as well as clinical and imaging correlates indicative of brain damage in these children. Routine ophthalmologic assessments in the early years can allow appropriate and timely interventions. PMID:26350726

    There is uncertainty about the proportion of children with autism spectrum disorders who do not develop phrase speech during the preschool years. The main purpose of this study was to examine this ratio in a population-based community sample of children. The cohort consisted of 165 children (141 boys, 24 girls) with autism spectrum disorders aged 4-6 years followed longitudinally over 2 years during which time they had received intervention at a specialized autism center. In this study, data collected at the 2-year follow-up were used. Three categories of expressive language were defined: nonverbal, minimally verbal, and phrase speech. Data from the Vineland Adaptive Behavior Scales-II were used to classify expressive language. A secondary objective of the study was to analyze factors that might be linked to verbal ability, namely, child age, cognitive level, autism subtype and severity of core autism symptoms, developmental regression, epilepsy or other medical conditions, and intensity of intervention. The proportion of children who met the criteria for nonverbal, minimally verbal, and phrase speech were 15%, 10%, and 75%, respectively. The single most important factor linked to expressive language was the child's cognitive level, and all children classified as being nonverbal or minimally verbal had intellectual disability.

    This review article addresses the question as to what methods can be used to investigate cranial structure and growth development in children 4 to 6 years old, and what the relevant reference values are for this age group. We screened the literature for epidemiological, longitudinal and cross-sectional studies investigating healthy children 4 to 6 years old without abnormalities and orthodontic therapy. Radiographic cephalometry is a practical, valid tool for analyzing craniofacial structure and growth processes. But it has several disadvantages, including the use of ionizing radiation, measuring points that are difficult to locate, no means of radiographic enlargement without distorting reference values, and the data's two-dimensionality. Anthropometry is another procedure for creating reference values for the craniofacial structure in children. Its advantages over radiographic cephalometry include three-dimensional results and no radiation exposure. Moreover, it yields precise and valid results for a wide variety of potential applications. In addition to these procedures, there are other techniques with which cranial structure and growth development in children 4 to 6 years old can be investigated. Those reported in the literature in this connection include standardized photographs, the creation of computerized and magnetic resonance images, and investigations performed on dry skulls. In short, there is great demand nowadays for investigations aimed at developing reference values for Caucasian children 4 to 6 years old. Radiographic cephalometry and anthropometry are two very common methods. Anthropometry is expected to become increasingly important because it involves no exposure to radiation.

    We underline the clinical importance of a specific eating disorder in 3 to 10 years old children, when the majority of the works about the prepubertal eating disorders focus either on the period just preceding adolescence (often between 10 and 13 years), or on the second half of the first year of the baby. Within the eating disorders described in the literature, we compare the clinical presentation of most of these 3 to 10 years old children with the food avoidance emotional disorder described during adolescence. These problems of eating behaviour (various selective eating with or without provoked vomiting) are ignored for a long time in these young children because of quite a satisfactory growth, but these children are often seen in emergency rooms because of a brutally complete eating refusal. Therapeutic consultations allow these children to express their fears about diseases, poisoning and death, for themselves or for their close relations, in particular the mother, without endangering their body. The early recognition and care of these difficulties of conciliation between the body and the thoughts impose a narrow collaboration between paediatric and psychiatric staffs.

    Abstract Objective: To compare the functional performance of students diagnosed with developmental delay (DD) up to two years of age with peers exhibiting typical development. Methods: Cross-sectional study with functional performance assessment of children diagnosed with DD up to two years of age compared to those with typical development at seven to eight years of age. Each group consisted of 45 children, selected by non-random sampling, evaluated for motor skills, quality of home environment, school participation and performance. ANOVA and the Binomial test for two proportions were used to assess differences between groups. Results: The group with DD had lower motor skills when compared to the typical group. While 66.7% of children in the typical group showed adequate school participation, receiving aid in cognitive and behavioral tasks similar to that offered to other children at the same level, only 22.2% of children with DD showed the same performance. Although 53.3% of the children with DD achieved an academic performance expected for the school level, there were limitations in some activities. Only two indicators of family environment, diversity and activities with parents at home, showed statistically significant difference between the groups, with advantage being shown for the typical group. Conclusions: Children with DD have persistent difficulties at school age, with motor deficit, restrictions in school activity performance and low participation in the school context, as well as significantly lower functional performance when compared to children without DD. A systematic monitoring of this population is recommended to identify needs and minimize future problems. PMID:26553573

    Children are at risk for developing posttraumatic stress disorder (PTSD) due to experiencing or living in a disaster area. The factors that increase the likelihood of a child developing PTSD need further clarification. We studied the factors associated with PTSD among children who experienced the tsunami in Sumatra, Indonesia. We conducted a cross sectional study in 2 subdistricts of Sumatra 5 years after experiencing a tsunami. Children aged 7-13 years were enrolled using stratified cluster sampling. A tsunami-modified version of The PsySTART Rapid Triage System was used to question children about their tsunami-specific traumatic experiences. Trauma symptoms were evaluated using the Trauma Symptom Checklist For Children (TSCC). The diagnosis of PTSD was made using the Child PTSD Symptom Scale (CPSS) and DSM-IV criteria. The data were analyzed with chi-square tests and multivariate logistic regression analysis with 95% confidence intervals (CI). A total of 262 children were enrolled in this study. The prevalence of PTSD in these children was 20.6%. On multivariate analysis, having experienced a delay in evacuation (PR = 4.5; 95% CI: 2.794-13.80; p < 0.001) and being unable to escape (PR = 13.07; 95% CI: 5.884-64; p < 0.001) were significantly associated with PTSD 5 years after the tsunami. Children who experienced a traumatic event in which they were unable to escape or when there is a delay in evacuation are at risk of developing PTSD and need appropriate treatment.

    We investigated test-retest stability of resting EEG asymmetry and power in the alpha frequency range across a 0.6 - to 3-year interval in 125 children (57 girls and 68 boys) for two age groups, 87 preschool children (3 to 5 year-olds) and 38 school-age children (6 to 9 year-olds). Children were from families with a parent’s history of unipolar or bipolar depression (36 girls and 43 boys) or control families with no parent history of depression nor any other psychiatric disorder (21 girls and 25 boys). Frontal EEG asymmetry stability was low to moderate; intraclass correlations ranged from zero to 0.48 in the eyes-open condition, and from 0.19 to 0.45 in the eyes-closed condition. Also, parietal EEG asymmetry was low to moderate; intraclass correlations ranged from 0.21 to 0.52 in the eyes-open condition and from 0.27 to 0.72 in the eyes-closed condition. Stability of EEG asymmetry was not related to age, sex of the child, or parent’s history of mood disorder. Frontal and parietal EEG power appeared moderately to highly stable. Intraclass correlations were between 0.65 and 0.86 in the eyes-open condition and between 0.52 and 0.90 in the eyes-closed condition. Although stability of EEG power was not statistical significantly different between preschool and school-age children, it consistently showed higher stability values in school-age children than in preschool children. Stability in school-aged children approached values as has been reported for adults. The findings provide partial support to the concept of frontal EEG asymmetry as a trait marker in childhood.

    The aim of this study was to assess factors affecting language developmental screening test results in 33.0- to 75.0-month-old children. The study group consists of 402 children, 172 (42.8%) boys and 230 (57.2%) girls, aged 33.0-75.0 months who were examined in four age groups: 3 years (33.0-39.0 months), 4 years (45.0-51.0 months), 5 years (57.0-63.0 months) and 6 years (69.0-75.0 months). Demographic data and medical history obtained by a standard questionnaire and Denver II Developmental Test results were evaluated. Maternal factors such as mother's age, educational level, and socioeconomic status (SES) correlated with language items in all age groups. Linear regression analysis indicated a significant effect of mother's education and higher SES on certain expressive and receptive language items at 3 and 4 years. Fine motor items were closely related to language items at all ages examined, while in the younger (3- and 4-year-old) group gross motor items also were related to language development. Maternal and socioeconomic factors influence language development in children: these effects, already discernible with a screening test, can be potential targets for social and educational interventions. The interpretation of screening test results should take into account the interaction between fine motor and language development in preschool children.

    The objectives of this research were: 1) to determine whether there were differences in empathy according to gender; 2) to analyze the relationships between empathy and social behaviour, self-concept, emotional stability, social interaction strategies, capacity to analyze emotions, intelligence, and creativity; and 3) to identify predicting variables of empathy. The sample consisted of 139 participants aged 10 to 12 years. ANOVA results showed gender differences in empathy, with significantly higher scores in females. Pearson coefficients suggest that participants with high empathy showed many positive social behaviours (prosocial, assertive, consideration, self-control, leadership), few negative social behaviors (passive, aggressive, antisocial, withdrawal) and many assertive strategies of social interaction; that they were named as prosocial classmates; and that they had high self-concept, high capacity to analyze negative emotions, high emotional stability and many behaviors and traits of creative personality. Multiple regression analyses permitted identification of the following predicting variables of empathy: high level of prosocial behaviour, low level of aggressive behaviour and high self-concept.

    OBJECTIVES To assess the proportion of children meeting the new Canadian Sedentary Behaviour Guidelines for the Early Years (zero to four years of age) and to describe parental attitudes toward and barriers to reducing screen time. METHODS: Participants included 657 children zero to four years of age from the Kingston, Ontario, area. From May to September 2011, parents completed a questionnaire regarding their child’s screen time and their attitudes toward and barriers to reducing their child’s screen time. RESULTS AND CONCLUSIONS: Approximately 32% of children younger than two years of age engaged in no screen time and approximately 46% of children two to four years of age engaged in <1 h per day; thereby, meeting the recommendations of the new guidelines. Most parents believed that their child did not engage in excessive screen time. Physicians and other health professionals should inform parents of these new guidelines and provide strategies to help their children meet targets. PMID:24381488

    The aim of this study was to analyse the development of verbal working memory in children with high-functioning autism compared to children with attention-deficit/hyperactivity disorder and typically developing children. A total of 34 children with high-functioning autism, 72 children with attention-deficit/hyperactivity disorder and 45 typically developing children (age 9-16 years) were included at baseline and followed up approximately 25 months later. The children were given a letter/number sequencing task to assess verbal working memory. The performance of children with high-functioning autism on verbal working memory did not improve after 2 years, while improvement was observed in children with attention-deficit/hyperactivity disorder and typically developing children. The results indicate a different developmental trajectory for verbal working memory in children with high-functioning autism compared to children with attention-deficit/hyperactivity disorder and typically developing children. More research is needed to construct a developmental framework more suitable for children with autism spectrum disorder.

    Background On March 11, 2011, a massive undersea earthquake and tsunami struck East Japan. Few studies have investigated the impact of exposure to a natural disaster on preschool children. We investigated the association of trauma experiences during the Great East Japan Earthquake on clinically significant behavior problems among preschool children 2 years after the earthquake. Method Participants were children who were exposed to the 2011 disaster at preschool age (affected area, n = 178; unaffected area, n = 82). Data were collected from September 2012 to June 2013 (around 2 years after the earthquake), thus participants were aged 5 to 8 years when assessed. Severe trauma exposures related to the earthquake (e.g., loss of family members) were assessed by interview, and trauma events in the physical environment related to the earthquake (e.g. housing damage), and other trauma exposure before the earthquake, were assessed by questionnaire. Behavior problems were assessed by caregivers using the Child Behavior Checklist (CBCL), which encompasses internalizing, externalizing, and total problems. Children who exceeded clinical cut-off of the CBCL were defined as having clinically significant behavior problems. Results Rates of internalizing, externalizing, and total problems in the affected area were 27.7%, 21.2%, and 25.9%, respectively. The rate ratio suggests that children who lost distant relatives or friends were 2.36 times more likely to have internalizing behavior problems (47.6% vs. 20.2%, 95% CI: 1.10–5.07). Other trauma experiences before the earthquake also showed significant positive association with internalizing, externalizing, and total behavior problems, which were not observed in the unaffected area. Conclusions One in four children still had behavior problems even 2 years after the Great East Japan Earthquake. Children who had other trauma experiences before the earthquake were more likely to have behavior problems. These data will be

    Most pediatric exercise intervention studies that evaluate the effect on skeletal traits include volunteers and follow bone mass for less than 3 years. We present a population-based 6-year controlled exercise intervention study in children with bone structure and incident fractures as endpoints. Fractures were registered in 417 girls and 500 boys in the intervention group (3969 person-years) and 835 girls and 869 boys in the control group (8245 person-years), all aged 6 to 9 years at study start, during the 6-year study period. Children in the intervention group had 40 minutes daily school physical education (PE) and the control group 60 minutes per week. In a subcohort with 78 girls and 111 boys in the intervention group and 52 girls and 54 boys in the control group, bone mineral density (BMD; g/cm(2) ) and bone area (mm(2) ) were measured repeatedly by dual-energy X-ray absorptiometry (DXA). Peripheral quantitative computed tomography (pQCT) measured bone mass and bone structure at follow-up. There were 21.7 low and moderate energy-related fractures per 1000 person-years in the intervention group and 19.3 fractures in the control group, leading to a rate ratio (RR) of 1.12 (0.85, 1.46). Girls in the intervention group, compared with girls in the control group, had 0.009 g/cm(2) (0.003, 0.015) larger gain annually in spine BMD, 0.07 g (0.014, 0.123) larger gain in femoral neck bone mineral content (BMC), and 4.1 mm(2) (0.5, 7.8) larger gain in femoral neck area, and at follow-up 24.1 g (7.6, 40.6) higher tibial cortical BMC (g) and 23.9 mm(2) (5.27, 42.6) larger tibial cross-sectional area. Boys with daily PE had 0.006 g/cm(2) (0.002, 0.010) larger gain annually in spine BMD than control boys but at follow-up no higher pQCT values than boys in the control group. Daily PE for 6 years in at study start 6- to 9-year-olds improves bone mass and bone size in girls and bone mass in boys, without affecting the fracture risk.

    In a rural cohort of 625 children registered from 1981 to 1983 in 10 villages of K.V. Block, Varanasi, 196 children were assessed for physical growth, development, intelligence and concept development between 1 and 3 years of age. Home environment was also assessed using Caldwell Home inventory. These rural children remained below 3rd centile of NCHS standard for weight, height, skull and mid-arm circumferences throughout the study. Malnourished children scored poorly in all the areas of development, i.e., motor, adaptive, language and personal social, 9% in Grade I and 16.6% children in Grade II + III had IQ less than 79 (inferior). Concept for color shape and size was poorly developed in malnourished children. Maternal involvement and stimulation was strongly associated with better behavior development and intelligence. Multiple regression analysis showed that the effect of home environment on development and intelligence was of a higher magnitude as compared to status and family variables and nutritional status during 1-3 years of age.

    2010-12-01

    The goal of this study was to predict the development of anxiety in 2½ year olds as a function of maternal anxiety and child inhibited temperament, and to test the mediating, moderating, and curvilinear effects of maternal sensitivity. Participants were 83 mothers and their 2½-year-old children (32 females). Maternal anxiety, child inhibition, and child anxiety were assessed by maternal report. Maternal sensitivity was rated based on the appropriateness and timeliness of mothers' responses to children's fear observed during their exposure to novel events in the laboratory and from mothers' diaries documenting their responses to children's fear in everyday situations. Gender predicted child anxiety, with mothers reporting girls as more anxious, as did child inhibition, with more inhibited children exhibiting more anxiety. Maternal sensitivity predicted child anxiety as a main effect and, in addition, inhibition moderated the curvilinear association of maternal sensitivity and child anxiety. For highly inhibited children, maternal sensitivity predicted anxiety in both a negative linear and a curvilinear fashion; anxiety decreased as maternal sensitivity increased up to a moderately high level, then increased at very high levels of maternal sensitivity. For less inhibited children, maternal sensitivity showed only a significant negative linear association with child anxiety.

    Introduction Cryptosporidium is an important cause of diarrhea in children and immune-compromised individuals. Recent advances in molecular diagnostics have led to the discovery of subtype families that are thought to be more commonly associated with diarrhea. We aimed to isolate and characterize Cryptosporidium spp among children with diarrhea in Jos, Nigeria. Methods Stool samples were collected from165 children aged 0-5 years with diarrhea. Cryptosporidium oocysts were examined by wet mount preparation, using formalin ether and a modified acid fast staining method. DNA was extracted from positive samples using QIAamp DNA stool mini kit and PCR-RFLP assay was carried out after quantification. Genotyping and phylogenetic analysis were done to determine the subtype families and their relatedness. Results From the 165 children studied, 8 (4.8%) were infected with Cryptosporidium. PCR-RFLP assay and genotype characterization found the following Cryptosporidium species: C. hominis 6 (75%) and C. parvum 2 (25.0%), with family subtypes Id-5, Ie-1 and IIa-1, IId-1 respectively.The most common species was C. hominis and the frequent subtype was C. hominis-Id 5 (62.5%). Conclusion Cryptosporidium is not an uncommon cause of diarrhea in children, with C. hominis being the dominant species. Also C. hominis Id is the commonest sub-family subtype. Put together, zoonotic species may be an important cause of diarrhea in children aged 0-5 years in Jos, Nigeria. PMID:28293369

    Purpose This study examined the outcomes of children with chronic immune thrombocytopenia (ITP). Materials and Methods We retrospectively analyzed the medical records of all patients diagnosed with ITP from January 1992 to December 2011 at our institution. Results A total of 128 patients (64%) satisfied the criteria for newly diagnosed ITP, 31 (15%) for persistent ITP, and 41 (21%) for chronic ITP. The median age at diagnosis was 4.5 years (range, 1 month to 18 years). The median platelet count at diagnosis was 32×109/L. A comparison of the initial treatment data from 2001 to 2011 with those from 1992 to 2000 showed that the number of bone marrow examinations decreased, whereas observation increased. Chronic ITP presented at an older age than newly diagnosed and persistent ITP (6.6 years vs. 3.8 years vs. 4.1 years, respectively); however, the difference did not reach statistical significance (p=0.17). The probability of complete remission of chronic ITP was 50% and 76% at 2 and 5 years after diagnosis, respectively. Patients aged <1 year at diagnosis had a significantly better prognosis than did older patients (hazard ratio, 3.86; p=0.02). Conclusion Children with chronic ITP showed a high remission rate after long-term follow-up. This study suggests that invasive treatments such as splenectomy in children with chronic ITP can be delayed for 4 to 5 years if thrombocytopenia and therapeutic medication do not affect the quality of life.

    2011-01-01

    Background Many studies have found a positive relationship between increased body weight and flat foot posture in children. Methods From a study population of 140 children aged seven to 10 years, a sample of 31 children with flat feet was identified by screening with the FPI-6. Basic anthropometric measures were compared between subjects with and without flat feet as designated. Results The results of this study, in contrast to many others, question the association of flat feet and heavy children. A significant relationship between foot posture and weight (FPI (L) r = -0.186 (p < 0.05), FPI(R) r = -0.194 (p < 0.05), waist girth (FPI (L) r = -0.213 (p < 0.05), FPI(R) r = -0.228 (p < 0.01) and BMI (FPI (L) r = -0.243 (p < 0.01), FPI(R) r = -0.263 (p < 0.01) was identified, but was both weak and inverse. Conclusions This study presents results which conflict with those of many previous investigations addressing the relationship between children's weight and foot posture. In contrast to previous studies, the implication of these results is that heavy children have less flat feet. Further investigation is warranted using a standardized approach to assessment and a larger sample of children to test this apparent contradiction. PMID:21513507

    Objectives. We identified factors associated with child bullying in the United States. Methods. We used the 2007 National Survey of Children’s Health to examine associations among child, parent, and community factors and bullying perpetration among children aged 10 to 17 years, using bivariate and stepwise multivariable analyses. Results. African American and Latino children and children living in poverty and who had emotional, developmental, or behavioral (EDB) problems had higher odds of bullying, as did children of parents who felt angry with their child or who felt their child bothered them a lot or was hard to care for; suboptimal maternal mental health was associated with higher bullying odds. Children who always or usually completed homework and had parents who talked with them and met all or most of their friends had lower bullying odds. Conclusions. Assessing children’s EDB problems, maternal mental health, and parental perceptions may identify children at risk for bullying. Parent–child communication, meeting children’s friends, and encouraging children academically were associated with lower bullying odds; these protective factors may be useful in designing preventive interventions.

    Background Sleep patterns may change over a person’s lifetime; however, the quantity and quality of sleep always depend on individual factors such as age, sex, and psychological and environmental factors. In children, sleep is as important as development. Quantitative sleep problems related to sleep onset and qualitative sleep disorders such as frequent awakenings may lead to insufficient sleep. Objectives This study aimed to assess the prevalence of sleep disorders among children 4 - 6 years old attending the health centers of Shahid Beheshti University of Medical Sciences, Tehran, Iran, in 2013. Patients and Methods This was a cross-sectional study on 400 children selected using a multistage sampling method. Data were collected by interviews. The questionnaire included two sections: a demographic section with questions about the demographic characteristics of the children and parents and a children’s sleep habit questionnaire (CSHQ). Data were analyzed by SPSS 16 and different statistical tests were used (P < 0.05). Results The mean age of the children was 64.27 ± 9.3 months. The prevalence of sleep disorders was 36.25%. Sleep disorders were significantly associated with age, height, body mass index, residence of children, father’s occupation, mother’s diseases, father’s drug abuse, and parents’ marital status (P < 0.05). Conclusions Sleep disorders in children threaten growth and development, and are dangerous for their health. Sleep disorders should be considered in the differential diagnosis of children’s learning and behavioral problems. PMID:27651942

    BACKGROUND Preventing obesity is a worldwide public health priority. In vulnerable children living in obesogenic environments, with easy access to high-caloric food, alterations in inhibitory control functions might favor excessive food intake and affect energy regulation. We hypothesized that overweight/obese children would present lower inhibitory control in comparison to normal weight children. METHODS We measured inhibitory control functions in 93 otherwise healthy overweight/obese and 92 normal weight 10-year-old children using the Stroop test and the Go/No-Go task. Event-related potentials were recorded during the Go/No-Go task. RESULTS Overweight/obese children showed slower reaction times (1248.6 ms (95% confidence interval (CI): 1182.9–1314.3) vs 1149.0 ms (95% CI: 1083.0–1215.1)) on the Stroop test, higher reaction time variability (0.25 (95% CI: 0.22–0.27) vs 0.21 (95% CI: 0.19–0.24)) on the Go/No-Go task and decreased P300 amplitude (4.1 µV (95% CI: 3.0–5.2) vs 6.4 µV (95% CI: 5.2–7.6)) on event-related potentials compared with normal weight children. CONCLUSIONS Our results indicate altered inhibitory control functions in otherwise healthy overweight/obese children, which might contribute to their excessive food consumption. PMID:25869603

    The present paper reports the findings of a study of scholastic backwardness among five to eight year old school going children. 1535 children were screened by their class teachers, of which 10.23% were found to have scholastic backwardness. No gender differences were noticed. The rates of specific difficulties such as reading, writing and arithmetic were found to be 4.69%, 5.15% and 15.96% respectively. About 26% of the scholastically backward children were also found to have psychological disturbance. In addition, they most often came from families which could not afford basic amenities, had fathers with alcohol dependence, inconsistent disciplining and poor parental interaction. They also had more frequent school changes, tution attendence and fewer hobbies compared to the scholastically superior children. PMID:21584131

    A study on school dropouts from primary and secondary school children was undertaken in September '91 from 16 schools at the headquarters of 8 Primary Health Centres, where 172 school dropouts were identified. A home visit was paid and information about socio-economic and cultural aspects was collected and a psychological screening was undertaken. Although there was no significant difference in overall dropout rates for both sexes, it increased sharply at 11 years of age in girls. The majority of children dropped out due to financial problems or unsatisfactory scholastic performance, and 142 (82.5%) of the 172 children studied were poor performers in one or more function tests. Maximum difficulty was observed in concept formation 87 (50.5%), followed by numerical ability in 78 (45%). Identification of children with learning difficulties and intervention using special educational methods within the framework of existing network of primary and secondary schools in rural areas is suggested.

    A cross-sectional hospital-based study was carried out at Tikrit teaching hospital, Iraq, from October 2004 to September 2005, to identify the prevalence and etiology of nosocomial infectious diarrhoea among children under 5 years of age. Of 259 children admitted to the paediatric ward for reasons other than diarrhoea and hospitalized for more than 3 days, clinical and laboratory analysis of stool samples showed nosocomial diarrhoea in 84 children (32.4%). The most common causative agents were enteropathogenic Escherichia coli (25.9%), Clostridium difficile (21.0%) and rotavirus (18.5%). Single infectious agents caused 63.1% of the cases, while mixed infections were detected in 16.7%; in 20.2% of children the cause remained unknown.

    The current study examines the processing of upright and inverted faces in 3-year-old children (n = 35). Event-related potentials (ERPs) were recorded during a passive-looking paradigm including adult and newborn face stimuli. We observed three face-sensitive components, the P1, the N170 and the P400. Inverted faces elicited shorter P1 latency and larger P400 amplitude. P1 and N170 amplitudes were larger for adult faces. To examine the role of experience in the development of face processing, the processing of adult and newborn faces was compared for children with a younger sibling (n = 23) and children without a younger sibling (n = 12). Age of sibling at test correlated negatively with P1 amplitude for adult and newborn faces. This may indicate more efficient processing of different face ages in children with a younger sibling and potentially reflects a more flexible face representation. PMID:24118716

    Three experiments examined whether cooperation or competition affects 4-year-old children's reasoning about other people's desires-which differed from their own-in a gift selection task. Experiment 1 (N=72) found that children's performance in selecting an adult-preferred gift for an adult experimenter was enhanced by a short period of preceding cooperative, but not competitive or individualistic, play with the experimenter. Experiment 2 (N=24) ruled out the alternative explanation that children resisted satisfying their opponent after competition. Experiment 3 (N=48) replicated the cooperation advantage in selecting a gift for someone else, indicating that children's understanding of diverse desires was generally improved by cooperation but not competition. These findings support the constructivist view of social development and highlight the advantage of cooperation.

    Children exposed to a technological disaster during an understudied part of the lifespan, preschool age and early middle childhood, were assessed in a 5-year follow-up regarding mental health problems, anxiety disorder symptoms, depressive symptoms, physical symptoms, and posttraumatic stress symptoms. Exposed children and their parents (n = 264) reported significantly more problems than controls (n = 515). The differences were greater for conduct problems (including hyperactivity) and physical symptoms, than for anxiety and depression. The long-term effects of a technological disaster on children of pre-school age at exposure appear to differ from those in children, who were victimized at a later age. This may reflect interference with completion of specific developmental tasks.

    Human growth is associated with complex interactions between genetic and environmental factors. While research has reported increased body size and body mass index (BMI) of Japanese children, few studies have compared the magnitude of increments in growth before and after World War II (WW II) and also considered other social and economical events that may have influenced the growth of children. The current study assessed the secular change in growth in Japanese children and adolescents aged between 6 and 17 years using data from the School Health Statistics Survey conducted between 1900 and 2000 with consideration of key social changes during the 20th Century. Over the 100-year period, Japanese boys had height and weight increments of 1.0-2.0 cm per decade and 0.4-1.7 kg per decade whereas girls had rates of 1.1-1.9 cm and 0.4-1.5 kg per decade, respectively. The rates of height increment were significantly (p<0.05) different between pre-, during and post-WW II periods. While Japanese children were considerably larger in 2000 compared to 1900, increments between 1950 and 1960 reflected catch-up growth to restore physical size seen in children prior to WW II. The increments in body size continued after 1960 with greatest changes seen across the pubertal years. While increments in BMI were evident in most age groups, the BMI of 17-year-old girls was consistent over the 100 years. Results clarified secular changes in growth in Japanese school children across the 20th Century and possible factors contributing to these changes.

    This study tests the hypothesis that a disjuncture between an individual's attained level of education and that held by average workers in the individual's occupation leads to higher mortality among those with a prolonged mismatched status. Swedish register data are used in a 19-year longitudinal mortality follow-up study of all causes and specific causes of mortality. Participants were all men and women born between 1926 and 1985 who were alive on 1 September 1990, who had concurrent information on their attained level of education and the specific occupation or industry they were employed in during this period for at least a consecutive year. An objective measure of educational and occupational mismatch was constructed from these data. Those with a stable, over-educated matched, or under-educated employment status are included in the final analysis (N = 2,482,696). Independent of social, family, employers' characteristics and prior health problems, the findings from a multivariate, stratified Cox regression analysis suggest there is excessive mortality among the over-educated, and a protective effect of under-education among native-born Swedish men and women.

    Abstract Objective: To analyze whether the information found on popular Internet sites are in accordance with the steps recommended by the Food Guide for Children Younger than Two Years of the Ministry of Health (2010). Methods: Descriptive/comparative study, carried out between August and October 2014, which carried out a search for popular sites (for lay people) in Portuguese, containing information on nutrition of children younger than two years. The Google search engine was used. These findings were compared with the Food Guide for Children Younger than Two Years of the Ministry of Health (2010). It was verified whether the information shown on the websites was in accordance with the Guide. Results: A total of 50 sites were analyzed, including blogs, food company websites and websites specialized in child nutrition. Only 10% of those pages correctly showed every step of the Food Guide. The recommendations were: exclusive breastfeeding up to six months of life (80%); complementary feeding from six months of life (36%); baby food consistency according to the guide (48%); encouraging the consumption of fruits and vegetables daily (60%). Regarding the complementary feeding safety and hygiene, 26% contained correct information. Only 36% correctly warned about which foods should be avoided in the first years of life. Conclusions: The information found on the sites is largely in disagreement with the Ministry of Health recommendations, which can lead to misconceptions in the nutritional care of the children younger than two years.

    Objectives The purpose of this article was to determine the incidence and predictors of vertebral fractures (VF) during the four years following diagnosis in pediatric acute lymphoblastic leukemia (ALL). Patients and Methods Children were enrolled within 30 days of chemotherapy initiation, with incident VF assessed annually on lateral spine radiographs according to the Genant method. Extended Cox’s models were used to assess the association between incident VF and clinical predictors. Results 186 children with ALL completed the baseline evaluation (median age 5.3 years, interquartile range 3.4 to 9.7, 58% boys). The VF incidence rate was 8.7 per 100 person-years, with a four-year cumulative incidence of 26.4%. The highest annual incidence occurred at 12 months (16.1%; 95% confidence interval (CI) 11.2 – 22.7), falling to 2.9% at four years (95% CI, 1.1 – 7.3). Half of the children with incident VF had moderate or severe VF and 39% of those with incident VF were asymptomatic. Every 10 mg/m2 increase in average daily glucocorticoid dose (prednisone equivalents) was associated with a 5.9-fold increased VF risk (95% CI, 3.0–11.8; p < 0.01). Other predictors of increased VF risk included: VF at diagnosis, younger age, and lower spine bone mineral density Z-scores at baseline and each annual assessment. Conclusions One quarter of children with ALL developed incident VF in the four years following diagnosis; most of the VF burden was in the first year. Over one third of children with incident VF were asymptomatic. Discrete clinical predictors of VF were evident early in the patient’s clinical course, including VF at diagnosis. PMID:26171800

    Purpose To determine the amount and time course of binocular visual acuity improvement during treatment of bilateral refractive amblyopia in children age 3 to <10 years old Design Prospective, multicenter noncomparative intervention Methods 113 children (mean age = 5.1 years) with previously untreated bilateral refractive amblyopia were enrolled at 27 community- and university-based sites and were provided optimal spectacle correction. Bilateral refractive amblyopia was defined as 20/40 to 20/400 best-corrected binocular acuity in the presence of ≥ 4.00 D hypermetropia by spherical equivalent and/or ≥ 2.00 D astigmatism in each eye. Best-corrected binocular and monocular visual acuities were measured at baseline and at 5, 13, 26 and 52 weeks. The primary study outcome was binocular acuity at one year. Results Mean binocular visual acuity improved from 0.50 logMAR (20/63) at baseline to 0.11 logMAR (20/25) at one year (mean improvement 3.9 lines, 95% confidence interval [CI] = 3.5 to 4.2). Mean improvement at one year for the 84 children with baseline binocular acuity of 20/40 to 20/80 was 3.4 lines (95% CI = 3.2 to 3.7) and for the 16 children with baseline binocular acuity of 20/100 to 20/320 was 6.3 lines (95% CI = 5.1 to 7.5). The cumulative probability of binocular acuity of 20/25 or better was 21% at 5 weeks, 46% at 13 weeks, 59% at 26 weeks, and 74% at 52 weeks. Conclusions Treatment of bilateral refractive amblyopia with spectacle correction improves binocular visual acuity in children age 3 to <10 years old, with most improving to 20/25 or better within one year.

    The majority of U.S. parents spank their children, often beginning when their children are very young. We examined families (N=2,788) who participated in a longitudinal community-based study of new births in urban areas. Prospective analyses examined whether spanking by the child's mother, father, or mother's current partner when the child was 1-year-old was associated with household CPS involvement between age 1 and age 5. Results indicated that 30% of 1-year-olds were spanked at least once in the past month. Spanking at age 1 was associated with increased odds of subsequent CPS involvement (adjusted odds ratio=1.36, 95% CI [1.08, 1.71], p<.01). When compared to non-spanked children, there was a 33% greater probability of subsequent CPS involvement for children who were spanked at age 1. Given the undesirable consequences of spanking children and a lack of empirical evidence to suggest positive effects of physical punishment, professionals who work with families should counsel parents not to spank infants and toddlers. For optimal benefits, efforts to educate parents regarding alternative forms of discipline should begin during the child's first year of life. PMID:24602690

    OBJECTIVE To analyze vaccination coverage and factors associated with a complete immunization scheme in children < 5 years old. METHODS This cross-sectional household census survey evaluated 1,209 children < 5 years old living in Bom Jesus, Angola, in 2010. Data were obtained from interviews, questionnaires, child immunization histories, and maternal health histories. The statistical analysis used generalized linear models, in which the dependent variable followed a binary distribution (vaccinated, unvaccinated) and the association function was logarithmic and had the children's individual, familial, and socioeconomic factors as independent variables. RESULTS Vaccination coverage was 37.0%, higher in children < 1 year (55.0%) and heterogeneous across neighborhoods; 52.0% of children of both sexes had no immunization records. The prevalence rate of vaccination significantly varied according to child age, mother's level of education, family size, ownership of household appliances, and destination of domestic waste. CONCLUSIONS Vulnerable groups with vaccination coverage below recommended levels continue to be present. Some factors indicate inequalities that represent barriers to full immunization, indicating the need to implement more equitable policies. The knowledge of these factors contributes to planning immunization promotion measures that focus on the most vulnerable groups.

    Background. Anemia is a wide spread public health problem in India which affects children. The present study evaluates the prevalence of anemia and status of various hematological parameters among children of Khurda district, Odisha. Method. A total of 313 children aged 0-12 years were enrolled for the study which included preschool (0-5 years) and school aged (6-12 years) groups. Hematological indicators were measured by standard procedures, which include red blood cell (RBC) indicators, white blood cell (WBC) indicators, and plasma ferritin. Results. Mean hemoglobin (Hb) of the study population was 10.43 ± 3.33 g/dL and prevalence of anemia was 62%. In this population, boys had a lower mean Hb value than that of the girls. All grades of anemia were higher among school age children than preschool children. Mean plasma ferritin was found to be higher in school age boys than their counterpart girls. The mean level of WBC count was found to be higher among preschool age boys than among the school age boys (p = 0.025). Conclusion. The prevalence of anemia was higher with concomitant acute infection among study population, which is a matter of concern. Since the hematological parameters are interrelated with each other as well as with the age and gender, relevant intervention strategy and constant monitoring are needed while providing public health nutrition programs to eradicate anemia.

    This is a descriptive cross-sectional study of the population base conducted in the town of Colombo in the state of Paraná. The objectives were to identify the prevalence of food insecurity in families that are beneficiaries of the Bolsa Família Program and the factors related to this condition, and describe the nutritional status of children under five years of age. Analyses of association were performed using Fisher's exact test. The sample included 442 families, of which 168 have children under five years of age. The Brazilian Food Insecurity Scale was applied to evaluate food insecurity and the nutritional status of the 199 children evaluated was determined by the height-for-age, weight-for-age and body mass-for-age indices in accordance with the WHO reference values for 2006. The prevalence of food insecurity was 81.6%. Overweight and stunting among children coexisted. Food insecurity was found to be associated with the height-for-age index among children under two years of age. The per capita income and food deficits influenced the situation of food insecurity significantly.

    In this 8-year longitudinal study, we traced the vocabulary growth of Chinese children, explored potential precursors of vocabulary knowledge, and investigated how vocabulary growth predicted future reading skills. Two hundred and sixty-four (264) native Chinese children from Beijing were measured on a variety of reading and language tasks over 8 years. Between the ages of 4 to 10 years, they were administered tasks of vocabulary and related cognitive skills. At age 11, comprehensive reading skills, including character recognition, reading fluency, and reading comprehension were examined. Individual differences in vocabulary developmental profiles were estimated using the intercept-slope cluster method. Vocabulary development was then examined in relation to later reading outcomes. Three subgroups of lexical growth were classified, namely high-high (with a large initial vocabulary size and a fast growth rate), low-high (with a small initial vocabulary size and a fast growth rate) and low-low (with a small initial vocabulary size and a slow growth rate) groups. Low-high and low-low groups were distinguishable mostly through phonological skills, morphological skills and other reading-related cognitive skills. Childhood vocabulary development (using intercept and slope) explained subsequent reading skills. Findings suggest that language-related and reading-related cognitive skills differ among groups with different developmental trajectories of vocabulary, and the initial size and growth rate of vocabulary may be two predictors for later reading development.

    2005-01-01

    Three-year-old children were tested on three categorization tasks of increasing levels of abstraction (used with adult baboons in an earlier study): the first was a conceptual categorization task (food vs toys), the second a perceptual matching task (same vs different objects), and the third a relational matching task in which the children had to sort pairs according to whether or not the two items belonged to the same or different categories. The children were tested using two different procedures, the first a replication of the procedure used with the baboons (pulling one rope for a category or a relationship between two objects, and another rope for the other category or relationship), the second a task based upon children's prior experiences with sorting objects (putting in the same box objects belonging to the same category or a pair of objects exemplifying the same relation). The children were able to solve the first task (conceptual categorization) when tested with the sorting into boxes procedure, and the second task (perceptual matching) when tested with both procedures. The children were able to master the third task (relational matching) only when the rules were clearly explained to them, but not when they could only watch sorting examples. In fact, the relational matching task without explanation requires analogy abilities that do not seem to be fully developed at 3 years of age. The discrepancies in performances between children tested with the two procedures, with the task explained or not, and the discrepancies observed between children and baboons are discussed in relation to differences between species and/or problem-solving strategies.

    Positive matrix factorization (PMF) was applied to identify the types of PM2.5 sources and corresponding mass contributions to PM2.5 mass concentrations using PM2.5 measurements obtained from Dec. 2007 to Oct. 2008 in Jinan, which is a highly polluted city in China. The reconstructed mass concentrations from six sources matched the observations, and the resolved sources constituted 98.91% of the PM2.5 mass concentrations. Secondary sources, the major source contributor, accounted for 55.15% of PM2.5 mass concentration, while several other sources, including coal burning (20.98%), soil dust (9.30%), motor vehicles (6.06%), biomass burning (4.55%), and industry (2.87%), contributed a total of 43.76%. The non-carcinogenic risk estimates showed the elemental risk for Mn, Co, S and Cr were high, with values larger than 0.1 being observed for the three groups. The total elemental risk in Jinan for the three groups was higher than 1, and the largest risk was present for children between the age of 6-12 followed by that for children between 2 and 6 years of age, indicating that citizens in Jinan, particularly children, faced more serious potential non-carcinogenic health risks.

    Little is known about the way in which the characteristics of autism spectrum disorder (ASD) develop and manifest across the age span in individuals with genetic syndromes. In this study we present findings from a two and a half year follow-up of the characteristics associated with ASD in three syndromes: Cornelia de Lange (CdLS), Fragile X (FXS), and Cri du Chat (CdCS). Parents and carers of 251 individuals (CdLS=67, CdCS=42, and FXS=142) completed the Social Communication Questionnaire (SCQ) at Time 1 (T1) and again two and a half years later (T2). The FXS and CdLS groups were more likely to meet the cut-offs for both autism and ASD and show greater severity of ASD related behaviors, at both T1 and T2, compared to the CdCS group. Older individuals (>15yrs) with CdLS were more likely to meet the cut off for ASD than younger individuals (≤15 yrs) with the syndrome and more likely to show greater severity of social impairments. In FXS repetitive behaviors were found to become less prominent with age and in CdCS social impairments were reported to be more severe with age. There were no significant changes between T1 and T2 in the severity of ASD characteristics in the CdCS and CdLS groups. The FXS group showed significantly fewer repetitive behaviors and less severe impairments in social interaction over this time frame. The findings suggest that while there may be similarities in overall severity and presentation of ASD characteristics in CdLS and FXS, these characteristics have divergent patterns of development within these groups.

    Background Childhood malnutrition is an important risk factor for child mortality and underlies close to 50% of child deaths worldwide. Previous studies have found an association between maternal depression and child malnutrition, but it is not known whether this association exists in Botswana. In addition, previous studies excluded non-maternal primary caregivers (PCGs). It is unclear whether the association between primary caregiver depression and child malnutrition remains when non-maternal PCGs are included. Aim The aim of this study was to determine if there is an association between PCG depression and malnutrition in children aged between 6 months and 5 years in Mahalapye, Botswana. Setting The study was conducted in the child welfare clinics of Xhosa and Airstrip clinics, two primary health care facilities in Mahalapye, Botswana. Methods This was a case control study. Cases were malnourished children aged between 6 months and 5 years, and controls were non-malnourished children matched for age and gender. The outcome of interest was depression in the PCGs of the cases and controls, which was assessed using the Patient Health Questionnaire 9 (PHQ 9), a depression screening tool. Results From a sample of 171 children, 84 of whom were malnourished, we found that the malnourished children were significantly more likely to have depressed PCGs (odds ratio = 4.33; 95% CI: 1.89, 9.89) than non-malnourished children in the 6-month to 5-year age group; the PCGs of malnourished children also had lower educational status. Conclusion This study found a significant association between PCG depression and child malnutrition. PMID:28155288

    Context: Organophosphate (OP) pesticides are neurotoxic at high doses. Few studies have examined whether chronic exposure at lower levels could adversely affect children’s cognitive development. Objective: We examined associations between prenatal and postnatal exposure to OP pesticides and cognitive abilities in school-age children. Methods: We conducted a birth cohort study (Center for the Health Assessment of Mothers and Children of Salinas study) among predominantly Latino farmworker families from an agricultural community in California. We assessed exposure to OP pesticides by measuring dialkyl phosphate (DAP) metabolites in urine collected during pregnancy and from children at 6 months and 1, 2, 3.5, and 5 years of age. We administered the Wechsler Intelligence Scale for Children, 4th edition, to 329 children 7 years of age. Analyses were adjusted for maternal education and intelligence, Home Observation for Measurement of the Environment score, and language of cognitive assessment. Results: Urinary DAP concentrations measured during the first and second half of pregnancy had similar relations to cognitive scores, so we used the average of concentrations measured during pregnancy in further analyses. Averaged maternal DAP concentrations were associated with poorer scores for Working Memory, Processing Speed, Verbal Comprehension, Perceptual Reasoning, and Full-Scale intelligence quotient (IQ). Children in the highest quintile of maternal DAP concentrations had an average deficit of 7.0 IQ points compared with those in the lowest quintile. However, children’s urinary DAP concentrations were not consistently associated with cognitive scores. Conclusions: Prenatal but not postnatal urinary DAP concentrations were associated with poorer intellectual development in 7-year-old children. Maternal urinary DAP concentrations in the present study were higher but nonetheless within the range of levels measured in the general U.S. population. PMID:21507776

    There are a large number of children with motor difficulties including those that have difficulty producing movements qualitatively well enough to improve in perceptuo-motor learning without intervention. We have developed a training method that supports active movement generation to allow improvement in a 3D tracing task requiring good compliance control. Previously, we tested a limited age range of children and found that training improved performance on the 3D tracing task and that the training transferred to a 2D drawing test. In the present study, school children (5-11years old) with motor difficulties were trained in the 3D tracing task and transfer to a 2D drawing task was tested. We used a cross-over design where half of the children received training on the 3D tracing task during the first training period and the other half of the children received training during the second training period. Given previous results, we predicted that younger children would initially show reduced performance relative to the older children, and that performance at all ages would improve with training. We also predicted that training would transfer to the 2D drawing task. However, the pre-training performance of both younger and older children was equally poor. Nevertheless, post-training performance on the 3D task was dramatically improved for both age groups and the training transferred to the 2D drawing task. Overall, this work contributes to a growing body of literature that demonstrates relatively preserved motor learning in children with motor difficulties and further demonstrates the importance of games in therapeutic interventions.

  11. Partial-year insurance coverage and the health care utilization of children.

    PubMed

    Leininger, Lindsey Jeanne

    2009-02-01

    A large literature examines the effects of health insurance on the health care utilization of children; however, most existing studies conceptualize coverage as a point-in-time measure rather than as a dynamic phenomenon. The major contribution of this article is its provision of estimates on the relationship between the duration of coverage over the course of a calendar year and health care utilization among children. Using child-level fixed-effects regression, we find that an incremental uninsured month is associated with a 0.7 percentage point decline in the probability of receiving a visit over the course of a year and a 3% decrease in the number of visits received. Children with intrayear coverage losses are more likely than those with continuous coverage to lose their usual source of care, which serves as a potential mechanism through which short gaps in coverage may lead to longer-term decrements in utilization.

    Very few exposure data are available for children in Europe and worldwide. The aim of this study was to assess the exposure to cosmetic products used on children aged 0-3 years using recent consumption data generated for the French population. Exposure was assessed using a probabilistic method for 24 products including cleanser, skin care, fragrance, solar and bottom products. The exposure data obtained in this study for children aged 0-3 years were higher than the values fixed by the SCCS for all common products: liquid shampoo, face moisturizer cream, toothpaste, shower gel and body moisturizer cream. Exposure was assessed for the first time for many products such as sunscreens, Eau de toilette and massage products. These new French exposure values will be useful for safety assessors and for safety agencies.

  14. Dental caries and erosion status of 12-year-old Hong Kong children

    PubMed Central

    2014-01-01

    Background This study aimed to assess the dental caries and erosion status of 12-year-old Hong Kong children and study the determinants of dental caries and dental erosion of these children. Methods The survey was performed from 2011 to 2012 with ethics approval. Stratified random sampling was adopted to select 12-year-old children in 7 primary schools in Hong Kong. The participating parents were asked to complete a self-administered questionnaire concerning their children’s diet and oral health habits. The children were examined for caries status with WHO criteria by 3 calibrated examiners. Detection of dental erosion followed Basic Erosive Wear Examination (BEWE) criteria. Results A total of 704 children were recruited and 600 (316 boys, 53%) participated in the survey. There were 124 children (21%) with caries experience (DMFT > 0) and their DMFT was 0.34 ± 0.76. About half of their decay was unfilled (DT = 0.16 ± 0.52) The DMFT of girls and boys were 0.45 ± 0.89 and 0.23 ± 0.61, respectively (p = 0.001). Girls also had a higher DT (0.21 ± 0.62 compared with 0.11 ± 0.41, p = 0.013) and FT than boys (0.23 ± 0.63 compared with 0.12 ± 0.44, p = 0.016). Most children (75%) had at least some sign of erosion (BEWE > 0), but no severe erosion (BEWE = 3). Logistic regression showed girls who consumed soft drinks and took vitamin C supplements had higher caries risk. Dental erosion was more severe among the children who had caries experience and consumed fruit juice. Conclusions The 12-year-old Hong Kong children had low caries experience, and almost half of the decay was left untreated. Although severe erosion was not found, many children had early signs of erosion. PMID:24397565

  15. Injuries from batteries among children aged <13 years--United States, 1995-2010.

    PubMed

    2012-08-31

    Injuries to children caused by batteries have been documented in the medical literature and by poison control centers for decades. Of particular concern is the ingestion of button batteries, especially those ≥20 mm in diameter (coin size), which can lodge in the esophagus, leading to serious complications or death. To estimate the number of nonfatal battery injuries among children aged <13 years, U.S. Consumer Product Safety Commission (CPSC) staff analyzed 1997-2010 data from the National Electronic Injury Surveillance System (NEISS). To identify fatal battery exposures, other CPSC databases covering 1995-2010 were examined, including the 1) Injury and Potential Injury Incident File; 2) Death Certificate Database (DTHS); and 3) In-Depth Investigation File (INDP). From 1997 to 2010, an estimated 40,400 children aged <13 years were treated in hospital emergency departments (EDs) for battery-related injuries, including confirmed or possible battery ingestions. Nearly three quarters of the injuries involved children aged ≤4 years; 10% required hospitalization. Battery type was reported for 69% of cases, and of those, button batteries were implicated in 58%. Fourteen fatal injuries were identified in children ranging in age from 7 months to 3 years during 1995-2010. Battery type was reported in 12 of these cases; all involved button batteries. CPSC is urging the electronics industry and battery manufacturers to develop warnings and industry standards to prevent serious injuries and deaths from button batteries. Additionally, public health and health-care providers can encourage parents to keep button batteries and products containing accessible button batteries (e.g., remote controls) away from young children.

    Aim: Obesity is the most common cause of insulin resistance and metabolic syndrome (MS). These are the most important risk factors for coronary heart disease (CHD). No evidence exists regarding the prevalence of the MS in children in sSrinagar city of Kashmir India. We aimed to evaluate the prevalence of MS in 8–18-year-old school-going children of Kashmir, India. Materials and Methods: In this cross-sectional study, 758 respondents in 8–18 years of age were randomly selected using a simple random sampling method. The self-designed questionnaire was individually completed after receiving a written informed consent. The weight, height, waist circumference (WC), body mass index (BMI), and blood pressure were measured using standard tools. Ten milliliters of blood was taken for measuring lipid profile and fasting blood sugar (FBS) of the school children. We determined MS according to the modified Adult Treatment Panel III (ATP III) criteria. Results: The prevalence of the MS was 3.8% (boys: 3.9%, girls: 3.8%) and the prevalence of obesity was 9.9% (boys: 9.9%, girls: 10.6%) among the studied children. Obese subjects had the highest proportion of MS compared with those at risk for overweight and those with normal weight (30.7% vs. 2.5% and 0.5%, respectively; P = 0.000). Conclusion: The MS is prevalent even in young children, so we suggest screening programs for children aged 8–18 years to control obesity and MS in the developing world. PMID:23776859

    Objectives. We estimated racial/ethnic differences in overweight and obesity in a national sample of 3-year-olds from urban, low-income families and assessed possible determinants of differences. Methods. Survey, in-home observation, and interview data were collected at birth, 1 year, and 3 years. We used logistic regression analyses and adjusted for a range of covariates in examining overweight and obesity differentials according to race/ethnicity. Results. Thirty-five percent of the study children were overweight or obese. Hispanic children were twice as likely as either Black or White children to be overweight or obese. Although we controlled for a wide variety of characteristics, we were unable to explain either White–Hispanic or Black–Hispanic differences in overweight and obesity. However, birthweight, taking a bottle to bed, and mother’s weight status were important predictors of children’s overweight or obesity at age 3 years. Conclusions. Children’s problems with overweight and obesity begin as early as age 3, and Hispanic children and those with obese mothers are especially at risk. PMID:17194857

    Antoniazzi, Diana; Snow, Pamela; Dickson-Swift, Virginia

    2010-06-01

    While the first 3 years of formal schooling have obvious importance for the transition to literacy, it must be remembered that learning to read is a linguistically-based task that draws heavily on mastery of key oral-language skills such as phonemic and morphological awareness, vocabulary development, and early syntax. In order to support the transition to literacy, and because oral language competence is important in its own right, it is vital that early-years teachers are skilled at identifying children who may be at risk of oral language impairment. In this study, 15 teachers completed the Children's Communication Checklist (second edition) on children in their first year of school (n = 149), and ratings were compared with results of screening using the Clinical Examination of Language Fundamentals Screening Test (fourth edition). Teacher ratings showed poor sensitivity and specificity in identifying children whose oral language skills require further investigation. Results are discussed in the light of recommendations for teacher pre-service education, SLP advocacy for oral language competence as a life-long determinant of health, issues in screening during the early years of school, and implications for further research.

    2013-01-01

    Objective To determine the influence of the presence of auditory neuropathy spectrum disorder (ANSD) on speech, language, and psycho-social development of children at three years of age. Design A population-based, longitudinal study was performed on outcomes of children with hearing impairment (LOCHI) in Australia. The demographic characteristics of the children were described, and their developmental outcomes were evaluated at three years of age. Performance of children with ANSD was compared with that of children without ANSD in the LOCHI study. Study sample There were 47 children with ANSD in the study sample. Results Sixty-four percent of children with ANSD have hearing sensitivity loss ranging from mild to severe degree, and the remaining have profound hearing loss. At three years, 27 children used hearing aids, 19 used cochlear implants, and one child did not use any hearing device. Thirty percent of children have disabilities in addition to hearing loss. On average, there were no significant differences in performance level between children with and without ANSD. Also, the variability of scores was not significantly different between the two groups. Conclusions There was no significant difference in performance levels or variability between children with and without ANSD, both for children who use hearing aids, and children who use cochlear implants.

    2011-01-01

    Developmental coordination disorder (DCD) refers to a delay in motor development that does not have any known medical cause. Studies conducted in English speaking societies have found that children with DCD display a higher co-occurrence rate of learning difficulties (e.g., problems in reading and writing) than typically developing (TD) children. The present study examined the reading and writing performance of school-aged children with DCD and TD children in Taiwan to determine whether reading and writing difficulties also co-occur with DCD in a non-English speaking society. The Chinese Reading Achievement Test and the Basic Reading and Writing Test were administered to 37 children with DCD (7.8 ± 0.6 years) and 93 TD children (8.0 ± 0.7 years). Children with DCD had significantly lower writing composite scores than TD children on the Basic Reading and Writing Test (105.9 ± 20.0 vs. 114.4 ± 19.9). However, there were no significant differences between children with DCD and TD children in their scores on the Chinese Reading Achievement Test and in their reading composite scores on the Basic Reading and Writing Test. These results contrasted interestingly with those obtained from English-speaking children: English-speaking DCD children showed poorer reading and poorer writing than English-speaking TD children. The possibility that the logographic nature of the Chinese script might have protected the DCD children against additional reading difficulty is discussed.

    2016-07-12

    Parental factors have been linked to childhood anxiety, hence, parental involvement in cognitive behavioral therapy (CBT) for anxious children has been examined. However, findings do not consistently show added effects of parent-enhanced CBT, longitudinal investigations are scarce and long-term effects unclear. In the present study, 40 out of 54 families who, 3 years previously, completed one of two types of CBT treatment: with limited or active parental involvement, were assessed using semi-structured diagnostic interviews. Diagnostic status at 3-years follow-up was compared between groups. Changes in diagnostic status across assessment points: posttreatment, 6-month and 3-year follow-up were analyzed within groups. Diagnostic change from 6-month to 3-year follow-up was compared between groups. Intent-to-treat analyses revealed no significant difference in diagnostic status between groups at 3-year follow-up. Nonetheless, children whose parents actively participated in treatment showed significantly more remission from 6-month to 3-year follow-up than children with limited parental participation.

  10. Children's Elicitation of Changes in Parenting during the Early Childhood Years

    PubMed Central

    Ansari, Arya; Crosnoe, Robert

    2015-01-01

    Using a subsample of the Early Childhood Longitudinal Study-Birth Cohort (ECLS-B; n = 1,550), this study identified parents who engaged in more developmentally problematic parenting—in the form of low investment, above average television watching, and use of spanking—when their children were very young (M = 24.41 months, SD = 1.23) but changed their parenting in more positive directions over time. Latent profile analysis and other techniques revealed that parents who demonstrated less optimal parenting behaviors when their children were 2 years old were more likely to be African American, from lower socioeconomic backgrounds, and experiencing greater depressive symptoms. Approximately half of such parents, however, made positive changes in their parenting practices, with 5% in the profile characterized by high investment and low use of spanking by the time that their children were in elementary school. These positive changes in parenting behavior were more likely to occur among parents whose children were already demonstrating early reading skills and less problem behavior. These potential “child effects”, suggesting that children elicited improvements in parenting, were more pronounced among higher income families but did not vary according to parents’ educational attainment. Findings from this study have important implications for intervention programs, suggesting that children's academic and behavioral skills can be leveraged as one means of facilitating positive parenting.

  11. Musical training influences linguistic abilities in 8-year-old children: more evidence for brain plasticity.

    PubMed

    Moreno, Sylvain; Marques, Carlos; Santos, Andreia; Santos, Manuela; Castro, São Luís; Besson, Mireille

    2009-03-01

    We conducted a longitudinal study with 32 nonmusician children over 9 months to determine 1) whether functional differences between musician and nonmusician children reflect specific predispositions for music or result from musical training and 2) whether musical training improves nonmusical brain functions such as reading and linguistic pitch processing. Event-related brain potentials were recorded while 8-year-old children performed tasks designed to test the hypothesis that musical training improves pitch processing not only in music but also in speech. Following the first testing sessions nonmusician children were pseudorandomly assigned to music or to painting training for 6 months and were tested again after training using the same tests. After musical (but not painting) training, children showed enhanced reading and pitch discrimination abilities in speech. Remarkably, 6 months of musical training thus suffices to significantly improve behavior and to influence the development of neural processes as reflected in specific pattern of brain waves. These results reveal positive transfer from music to speech and highlight the influence of musical training. Finally, they demonstrate brain plasticity in showing that relatively short periods of training have strong consequences on the functional organization of the children's brain.

    Emotional facial expressions are important social cues that convey salient affective information. Infants, younger children, and adults all appear to orient spatial attention to emotional faces with a particularly strong bias to fearful faces. Yet in young children it is unclear whether or not both happy and fearful faces extract attention. Given that the processing of emotional faces is believed by some to serve an evolutionarily adaptive purpose, attentional biases to both fearful and happy expressions would be expected in younger children. However, the extent to which this ability is present in young children and whether or not this ability is genetically mediated is untested. Therefore, the aims of the current study were to assess the spatial-attentional properties of emotional faces in young children, with a preliminary test of whether this effect was influenced by genetics. Five-year-old twin pairs performed a dot-probe task. The results suggest that children preferentially direct spatial attention to emotional faces, particularly right visual field faces. The results provide support for the notion that the direction of spatial attention to emotional faces serves an evolutionarily adaptive function and may be mediated by genetic mechanisms.

  13. Children's Elicitation of Changes in Parenting during the Early Childhood Years.

    Ansari, Arya; Crosnoe, Robert

    Using a subsample of the Early Childhood Longitudinal Study-Birth Cohort (ECLS-B; n = 1,550), this study identified parents who engaged in more developmentally problematic parenting-in the form of low investment, above average television watching, and use of spanking-when their children were very young (M = 24.41 months, SD = 1.23) but changed their parenting in more positive directions over time. Latent profile analysis and other techniques revealed that parents who demonstrated less optimal parenting behaviors when their children were 2 years old were more likely to be African American, from lower socioeconomic backgrounds, and experiencing greater depressive symptoms. Approximately half of such parents, however, made positive changes in their parenting practices, with 5% in the profile characterized by high investment and low use of spanking by the time that their children were in elementary school. These positive changes in parenting behavior were more likely to occur among parents whose children were already demonstrating early reading skills and less problem behavior. These potential "child effects", suggesting that children elicited improvements in parenting, were more pronounced among higher income families but did not vary according to parents' educational attainment. Findings from this study have important implications for intervention programs, suggesting that children's academic and behavioral skills can be leveraged as one means of facilitating positive parenting.

    This study investigated the dental health status, dietary habits, oral hygiene levels, and caretaker risk indicators among Taiwanese children. This cross-sectional purposive sampling study included 256 aboriginal children, 6 to 9 years old, living in remote regions in southern Taiwan. Participants received dental examinations, and questionnaires were completed by caretakers. Data were analyzed using the χ(2) test, t test, and multiple logistic regressions. The deft (sum of decayed, extracted, and filled primary teeth) and defs (sum of the decayed, extracted, and filled primary dentition surfaces) indices were affected by the frequencies of drinking sweetened beverages (P = .0006) and daily toothbrushing (P = .0032). Caretakers' toothbrushing frequency was a significant predictor of children's oral hygiene status (P < .0001). The odds ratio for children of caretakers with betel quid chewing habits having poor oral hygiene was 2.04 (P = .0184). Oral hygiene among aboriginal children in this study was inadequate. Caretakers' toothbrushing frequency and betel quid habit were significant predictors of poor children's oral hygiene.

    Outdoor air pollution has been associated with decrements in lung function and growth of lung function in school-age children. Lung function effects have not been examined in preschoolers, with the exception of one study on minute ventilation in newborns. Our goal was to assess the relationship between long- and short-term exposure to traffic-related air pollution and interrupter resistance in 4-year-old children. Lung function was measured using the interrupter resistance method in children participating in a Dutch birth cohort study. Long-term average air pollution concentrations of fine particulate matter, nitrogen dioxide and soot at the residential address at birth were assessed using land-use regression models. Daily average air pollution concentrations on the day of clinical examination were obtained from the Dutch National Air Quality Monitoring Network. Significant associations were found between long-term average air pollution concentrations and interrupter resistance. Interrupter resistance increased by 0.04 kPa·s·L(-1) (95% CI 0.01-0.07) per interquartile range increase (3.3 μg·m(-3)) in fine particle concentration. Short-term exposure was not associated with interrupter resistance. Long-term exposure to traffic-related air pollution was associated with increased interrupter resistance in 4-year-old children, supporting previous birth cohort studies reporting effects of air pollution on subjectively reported respiratory symptoms in preschool children.

    Enteric pathogens are commonly associated with diarrhea among malnourished children. This study aimed to determine the association between the severity of diarrheal illnesses and malnutrition among under 5-year-old children. During 2010 and 2011, we studied 2,324 under 5-year-old diarrheal children with mild disease (MD) and moderate-to-severe disease (MSD) attending a hospital in Bangladesh. Children with MSD were more likely to be malnourished compared with children with MD (35% versus 24%, P < 0.001). In multivariate analysis, malnutrition (odds ratio [95% confidence interval] = 1.53 [1.22, 1.92]), age of the child (24-59 months; 1.67 [1.28, 2.19]), fever (1.65 [1.28, 2.12]), abdominal pain (1.87 [1.48, 2.37]), straining (5.93 [4.80, 7.33]), and infection with Shigella (3.26 [2.38, 4.46]) and Vibrio cholerae (2.21 [1.07, 4.58]) were shown to be significantly associated with MSD. Factors significantly associated with malnutrition were disease severity (1.56 [1.24, 1.95]), age (24-59 months; 1.75 [1.38, 2.22]), mother's schooling (1.54 [1.16, 2.04]), and monthly household income (1.71 [1.42, 2.07]). Childhood malnutrition was associated with dysentery and dehydrating diarrhea.

    Although there is great interest in identifying the neural correlates of cognitive processes that create risk for psychopathology, there is a paucity of research in young children. One event-related potential (ERP), the N2, is thought to index conflict monitoring and has been linked cognitive and affective risk factors for anxiety. Most of this research, however, has been conducted with adults, adolescents, and older children, but not with younger children. To address this gap, the current study examined 26 4-8-year-olds, who completed a cued flanker task while EEG was continuously recorded. We assessed whether the N2 was detectable in this group of young children and examined associations between the N2 and factors reflecting affective risk (e.g., reduced executive attention, temperamental effortful control, and temperamental surgency). We documented an N2 effect (greater N2 amplitude to incongruent versus congruent flankers), but only in children older than 6 years of age. Increases in the N2 effect were associated with less efficient executive attention and lower temperamental effortful control. We discuss the implications of these findings and consider how they may inform future studies on biomarkers for cognitive and affective risk factors for anxiety.

    Research demonstrates that literacy and academic achievement are predicated on the emergent literacy knowledge and skills children acquire from birth up to 4 years of age. Parents are children's first and most important language and literacy teachers, yet not all parents have the capacity to establish an adequate early literacy foundation. Efforts to address this situation have resulted in numerous programs aimed at fostering emergent literacy development. This systematic review evaluates evidence on the effectiveness of parent-mediated interventions that increase the time parents spend reading with young children up to 4 years old. Four studies met inclusion criteria, reporting outcomes for 664 children. Three provided data for meta-analysis of effects on reading duration. The standardized mean difference in reading duration was 1.61 (95% CI, 1.03, 2.19 fixed-effect), favoring intervention over control. Results indicate that interventions aimed at increasing the amount of time parents spend reading interactively with their children yield positive results. Findings also demonstrate that pediatric primary care providers are well positioned to deliver reading promotion programs to parents and preschoolers.

    Numerical cognition is based on two components - number processing and calculation. Its development is influenced by biological, cognitive, educational, and cultural factors. The objectives of the present study were to: i) assess number processing and calculation in Brazilian children aged 7-12 years from public schools using the Zareki-R (Battery of neuropsychological tests for number processing and calculation in children, Revised; von Aster & Dellatolas, 2006) in order to obtain normative data for Portuguese speakers; ii) identify how environment, age, and gender influences the development of these mathematical skills; iii) investigate the construct validity of the Zareki-R by the contrast with the Arithmetic subtest of WISC-III. The sample included 172 children, both genders, divided in two groups: urban (N = 119) and rural (N = 53) assessed by the Zareki-R. Rural children presented lower scores in one aspect of number processing; children aged 7-8 years demonstrated an inferior global score than older; boys presented a superior performance in both number processing and calculation. Construct validity of Zareki-R was demonstrated by high to moderate correlations with Arithmetic subtest of WISC-III. The Zareki-R therefore is a suitable instrument to assess the development of mathematical skills, which is influenced by factors such as environment, age, and gender.

    A large body of work has focused on children's ability to attribute mental states to other people, and whether these abilities are influenced by the extent and nature of children's social interactions. However, it remains largely unknown which developmental factors shape children's ability to influence the mental states of others. Building on the suggestion that collaborative experiences early in life might be crucial for the emergence of mental coordination abilities, here we assess the relative contribution of social exposure to familial and non-familial agents on children's communicative adjustments to their mental model of an addressee ('audience design'). During an online interactive game, five-year-olds spontaneously organized their non-verbal communicative behaviors according to their beliefs about an interlocutor. The magnitude of these communicative adjustments was predicted by the time spent at daycare, from birth until four years of age, over and above effects of familial social environment. These results suggest that the degree of non-familial social interaction early in life modulates the influence that children's beliefs have on their referential communicative behavior.

    Children are less skilled than adults at making judgments about facial expression. This could be because they have not yet developed adult-like mechanisms for visually representing faces. Adults are thought to represent faces in a multidimensional face-space, and have been shown to code the expression of a face relative to the norm or average face in face-space. Norm-based coding is economical and adaptive, and may be what makes adults more sensitive to facial expression than children. This study investigated the coding system that children use to represent facial expression. An adaptation aftereffect paradigm was used to test 24 adults and 18 children (9 years 2 months to 9 years 11 months old). Participants adapted to weak and strong antiexpressions. They then judged the expression of an average expression. Adaptation created aftereffects that made the test face look like the expression opposite that of the adaptor. Consistent with the predictions of norm-based but not exemplar-based coding, aftereffects were larger for strong than weak adaptors for both age groups. Results indicate that, like adults, children's coding of facial expressions is norm-based.

    Abstract Objective: to estimate the prevalence and factors associated with preoperative anxiety in children who wait for outpatient surgery. Method: cross-sectional analysis of baseline data of a prospective cohort study that investigates the predictors of postoperative pain in children aged 5-12 years submitted to inguinal and umbilical hernia repair. It was selected 210 children, which were interviewed in the preoperative holding area of a general hospital. Anxiety was evaluated using the modified Yale Preoperative Anxiety Scale (mYPAS). Sociodemographic and clinical variables were analyzed as exposure and anxiety (mYPAS final score>30) as outcome. Logistic regression was used to identify factors associated with preoperative anxiety. Results: forty-two percent (42.0%) of children presented preoperative anxiety (CI95%: 35.7%-48.6%), with mean scores equal to 30.1 (SD=8.4). Factors associated with preoperative anxiety were: age group of 5-6 years (OR=2.28; p=0.007) and socioeconomic status classified as class C (OR=2.39; p=0.016). Conclusion: the evaluation of children who wait for outpatient surgery should be multidimensional and comprise information on age and socioeconomic status, in order to help in the identification and early treatment of preoperative anxiety.

    This is a retrospective review of clinical data and audiovestibular test results from four children in whom symptoms suggesting Ménière's disease started at 4-7 years of age. The four patients all had spontaneous recurrent attacks of (spinning) vertigo and fluctuating low frequency sensorineural hearing loss from an early age, suggesting a diagnosis of definite Ménière's disease. Presumably, due to age-related inability to communicate auditory symptoms, the children did not initially meet requirements for a diagnosis of Ménière's disease. However, by 8 years of age, all four children reported tinnitus and/or fullness in the affected ear and, thus, met the AAO criteria for Ménière's disease. Even if information on subjective auditory symptoms is missing, it is reasonable to consider young children with idiopathic spontaneous recurrent attacks of vertigo in whom audiograms reveals fluctuating low frequency hearing loss to have Ménière's disease. This report is a reminder that Ménière's disease may also occur in young children.

    Thyroid carcinoma (TC) has an increasing incidence in the last decade and continues to represent the most frequent form of endocrine tumor. The aim of the study was to analyze the pediatric files of TC from the registry of "Prof. Dr. Ion Chiricuta" Institute of Oncology Cluj-Napoca, Romania (IOCN) and to provide the data related to the impact of nuclear fallout of Chernobyl on this pathology. We studied 72 children with TC treated between 1991 and 2010. The mean age was 15.3 years; the ratio female/male was 6.2:1. Twenty-nine children (40.2%) revealed metastasis in regional lymph nodes or lungs at the initial diagnostic. There were 63 differentiated thyroid carcinoma (DTC), 6 cases with medullary cancer (MC), 1 case with anaplastic carcinoma (AC), and 2 mixed cases. All patients underwent total thyroidectomy and the radioiodine was administered in 64 cases (activities between 1.1 - 28.1 GBq I-131). Fifty-two children (80.5%) are free of disease, 8 are in partial remission and 4 children are in evolution of the disease at minimum 12 months of follow-up. The incidence of TC was significantly increased 10 years after the accident. In the years after, the increasing trendline was stopped and at 25 years, the number of cases is stationary. The diagnosis of pediatric TC is made frequently in metastatic disease and the therapies must be conducted for many years till complete remission. A more clear strategy adapted to children is needed in the future.

    Background: Existing guidelines on screening children less than 5 years of age for developmental delay vary. In this systematic review, we synthesized the literature on the effectiveness and harms of screening for developmental delay in asymptomatic children aged 1-4 years. Methods: We searched MEDLINE, Embase and PsychINFO for relevant articles published to June 16, 2015. We identified studies that included children aged 1-4 years who were not at high risk of developmental delay, screened in a primary care setting. Randomized trials and controlled cohort studies were considered for benefits (cognitive, academic and functional outcomes); no restrictions on study design were imposed for the review of harms. Results: Two studies were included. One used the Ages and Stages Questionnaire II for screening and reported significantly more referrals to early intervention in the intervention groups than in the control group (relative risk [RR] 1.95, 95% confidence interval [CI] 1.49-2.54, in the intervention group with office support and RR 1.71, 95% CI 1.30-2.25, in the intervention group without office support). The time to referral was 70% shorter in the intervention group with office support (rate ratio 0.30, 95% CI 0.19-0.48) and 64% shorter in the intervention group without office support (rate ratio 0.36, 95% CI 0.23-0.59), compared with the control group. The other study used the VroegTijdige Onderkenning Ontwikkelingsstoornissen Language Screening instrument to screen children aged 15 months at enrolment for language delay. It reported no differences between groups in academic performance outcomes at age 8 years. Interpretation: The evidence on screening for developmental delay in asymptomatic children aged 1-4 years is inconclusive. Further research with longer-term outcomes is needed to inform decisions about screening and screening intervals. PMID:27226967

    BACKGROUND—There is evidence of a positive association between asthma and obesity in adults and in children. We investigated, in a large sample of English and Scottish primary school children, whether there is a consistent association between fatness and asthma symptoms in Britain.
METHODS—A cross sectional analysis was made of 18 218 children aged 4-11 years who participated in the 1993 or 1994 surveys of the National Study of Health and Growth (NSHG). Children belonged either to English or Scottish representative samples, or an English inner city sample. Asthma attacks in the previous year, occasional wheeze, or persistent wheeze were the symptoms used in the analysis. Body mass index (BMI) and the sum of triceps and subscapular skinfolds converted to standard deviation scores (SDS) were used to assess levels of fatness.
RESULTS—A total of 14 908 children (81.8%) were included in the analysis. In the multiple logistic analysis BMI and asthma (asthma attacks or wheeze) were associated in the representative sample (OR for the comparison of the 10th and 90th centiles of BMI 1.28,95% CI 1.11 to 1.48), but sum of skinfolds was unrelated to asthma symptoms in most analyses. The association between asthma and BMI was stronger in girls than in boys in the inner city sample, but less convincingly in the representative sample.
CONCLUSIONS—Levels of obesity are associated with asthma symptoms regardless of ethnicity. The association is more consistent for BMI than for sum of skinfolds, partly because obese children are more advanced in their maturation than other children. There is some evidence that, as in adults, the association is stronger in girls than in boys, but only in the multiethnic inner city sample.

    The aim of the present study was to determine the effects of adenotonsillectomy on height, weight and body mass index (BMI) in children under 12 years old, with or without airway obstruction and evaluation of the risk of overweight in them. In this case-control study, 120 children with the age of 2-12 years old were studied; 60 children as case group who underwent adenotonsillectomy and 60 healthy children as control group. After collecting the data related to appetite status and sleep breathing disorder of the case group, height, weight and BMI have been measured for all children in two stages; preoperatively and 6 months later. Also in the case group, BMI percentiles, pre and postoperatively have been calculated. Patients with Low appetite in the initiation and at the end of the study in the case group were 80% and 8.3% respectively (P=0.01). Mean of height, weight and BMI variation after 6 months were significantly different between case and control groups (P<0.05). BMI percentiles in the case group preoperatively were: 20% underweight, 67% healthy weight, 10% at risk of over weight, 3% over weight. Postoperatively, after 6 months BMI percentiles in order of above frequency were: 10%, 57%, 22% and 11% (P=0.02). Analysis of the results showed that adenotonsillectomy can lead to increase of height, weight, BMI and appetite not only in the children with low weight due to airway obstruction but also in the normal weight and over weight children. Therefore risk of overweight should be mentioned as a probable undesirable outcome of adenotonsillectomy.

    The main aims of this study were to develop norms for the Wisconsin Card Sorting Test in 6- to 11-year-old children in Taiwan; to explore the effect of sex, age, birth order, number of siblings, and parental education on WCST performance in 6- to 11-year-old children; and to make a comparison of WCST performance between children in Taiwan and the USA. The results of this comparison of developmental norms of school children in Taiwan and the United States may facilitate the WCST as a clinical or research instrument in combination with other test procedures to assess aspects of cognitive and neuropsychological functioning of school children.

    Efficacy trials of antihelminthic therapies conducted in Africa have reported improvements in children's growth, but nutritional evaluations of large-scale deworming programs are lacking. We evaluated the first-year effect on growth of a school-based deworming program in Zanzibar, where growth retardation occurs in school children. Children in four primary schools were given thrice-yearly mebendazole (500 mg) and compared with children in four schools that received twice-yearly mebendazole and children in four non-program schools. Evaluation schools were randomly selected and allocated to control, twice-yearly or thrice-yearly deworming. Approximately 1000 children in each program group completed the 1-y follow-up. Children <10 y old gained 0.27 kg more weight (P < 0.05) and 0.13 cm more height (P = 0.20) in the twice-yearly group, and 0. 20 kg more weight (P = 0.07) and 0.30 cm more height (P < 0.01) in the thrice-yearly group, compared with the control group. Children <10 y old with higher heights-for-age at baseline had higher weight and height gains in response to deworming. In children >/=10 y old, overall program effects on height or weight gains were not significant. But in this age range, younger boys had significant improvements in height gain with thrice-yearly deworming, and children with higher heights-for-age had greater improvements in weight gain with deworming. We conclude that the deworming program improved the growth of school children, especially children who were younger and less stunted, but the improvements were small. More effective antihelminthic regimens or additional dietary or disease control interventions may be needed to substantially improve the growth of school children in areas such as Zanzibar.

    Background: Prenatal stress seems to have long-lasting effects on biological and psychological processes of the offspring. However, to date, there have been no studies investigating the effects of prenatal glucocorticoid exposure on psychological, endocrine, and autonomic responses to a standardized psychosocial stress test in children. Methods: A sample of 115 healthy, 10-year-old children was examined. The Glucocorticoids + Tocolytics group was characterized by tocolytic treatment of the mothers due to preterm labor (n = 43). In addition, the pregnant women received glucocorticoid treatment in order to accelerate fetal lung maturation in case of preterm birth. The first comparison group (Tocolytics) consisted of children whose mothers also experienced preterm labor, but did not receive glucocorticoid treatment (n = 35). In the second comparison group (CONTROL), children whose mothers had a complication-free pregnancy were assessed (n = 37). Psychological parameters (stress appraisal and mood) using self-report questionnaires as well as salivary cortisol, salivary alpha-amylase, and heart rate were measured during a standardized psychosocial stress test (Trier Social Stress Test for Children). Results: Group comparisons revealed that a subscale of stress appraisal, control expectancies, significantly differed in children who were prenatally exposed to glucocorticoids as compared to both comparison groups (F = 4.889, p = 0.009). Furthermore, significant differences between the groups were revealed for salivary cortisol. With respect to overall stress appraisal and heart rate, trends toward significance were observed between the three groups. Conclusion: At the age of ten, those children who have been exposed to prenatal maternal glucocorticoids show changed psychobiological stress reactivity to a standardized psychosocial stress test as compared to control children.

    Background: Body shape and size are typically described using measures such as body mass index (BMI) and waist circumference, which predict disease risks in adults. However, this approach may underestimate the true variability in childhood body shape and size. Objective: To use a comprehensive three-dimensional photonic scan approach to describe variation in childhood body shape and size. Subjects/Methods: At age 6 years, 3350 children from the population-based 2004 Pelotas birth cohort study were assessed by three-dimensional photonic scanner, traditional anthropometry and dual X-ray absorptiometry. Principal component analysis (PCA) was performed on height and 24 photonic scan variables (circumferences, lengths/widths, volumes and surface areas). Results: PCA identified four independent components of children's body shape and size, which we termed: Corpulence, Central:peripheral ratio, Height and arm lengths, and Shoulder diameter. Corpulence showed strong correlations with traditional anthropometric and body composition measures (r>0.90 with weight, BMI, waist circumference and fat mass; r>0.70 with height, lean mass and bone mass); in contrast, the other three components showed weak or moderate correlations with those measures (all r<0.45). There was no sex difference in Corpulence, but boys had higher Central:peripheral ratio, Height and arm lengths and Shoulder diameter values than girls. Furthermore, children with low birth weight had lower Corpulence and Height and arm lengths but higher Central:peripheral ratio and Shoulder diameter than other children. Children from high socio-economic position (SEP) families had higher Corpulence and Height and arm lengths than other children. Finally, white children had higher Corpulence and Central:peripheral ratio than mixed or black children. Conclusions: Comprehensive assessment by three-dimensional photonic scanning identified components of childhood body shape and size not captured by traditional anthropometry or

    Ambient fine particulate matter (PM2.5) has a large and well-documented global burden of disease. Our analysis uses high-resolution (10 km, global-coverage) concentration data and cause-specific integrated exposure-response (IER) functions developed for the Global Burden of Disease 2010 to assess how regional and global improvements in ambient air quality could reduce attributable mortality from PM2.5. Overall, an aggressive global program of PM2.5 mitigation in line with WHO interim guidelines could avoid 750 000 (23%) of the 3.2 million deaths per year currently (ca. 2010) attributable to ambient PM2.5. Modest improvements in PM2.5 in relatively clean regions (North America, Europe) would result in surprisingly large avoided mortality, owing to demographic factors and the nonlinear concentration-response relationship that describes the risk of particulate matter in relation to several important causes of death. In contrast, major improvements in air quality would be required to substantially reduce mortality from PM2.5 in more polluted regions, such as China and India. Moreover, forecasted demographic and epidemiological transitions in India and China imply that to keep PM2.5-attributable mortality rates (deaths per 100 000 people per year) constant, average PM2.5 levels would need to decline by ∼20-30% over the next 15 years merely to offset increases in PM2.5-attributable mortality from aging populations. An effective program to deliver clean air to the world's most polluted regions could avoid several hundred thousand premature deaths each year.

    Introduction Obesity is a growing health problem associated with metabolic derangements and cardiovascular disease. Accumulating evidence links the accumulation of visceral adipose tissue (VAT) to these obesity related health risks in adults. Childhood obesity is associated with a lifetime risk of cardiovascular disease and poses a serious challenge to future health care. In children, there is much less data on the prevalence and gender differences of visceral obesity than in adults. This study aims to provide reference values for VAT in children 10–11 years of age. Methods In a cross-sectional study performed in the north western part of theNetherlands, healthy children of 10–11 years of age, were recruited from primary schools. Anthropometric data consisting of height, weight, waist circumference (WC) and BMI were measured. Body composition was measured using DXA, providing measures for bone mineral content, total fat mass (TFM), lean body mass (LBM) and VAT. Results 217 children were eligible for this study. Girls appeared to have a greater TFM (31.4% vs 27.5% of total body weight (TBW); P < .01) but lower VAT (0.3% vs 0.5% of TBW;P < .01) than boys, whereas boys had higher LBM (65.4% vs 69.3% TBW;P < .01). Median VAT area (cm2) was 41.1 for boys and 22.4 for girls (P < .01). Moderate to strong correlations were found for WC and BMI with VAT (boys: r = .664 and r = .630; Girls r = .699 and r = .546 respectively all P < .001). Discussion This study shows gender specific differences in VAT percentiles in healthy non-obese 10–11 year old children as measured by DXA that may serve as reference values in children. Independent of BMI and WC, girls tend to have more TFM but less VAT and LBM than boys. PMID:27788168

    This study aimed to evaluate longitudinal changes in bone mineral density (BMD) and bone mineral content (BMC) in children with cancer during the first year of treatment. Thirty pediatric cancer patients (median age 11.2 [range 3.8-17.4] yr; 21 boys, 9 girls; 19 hematologic malignancies, 11 solid tumors) and 30 healthy controls were enrolled. Dual energy X-ray absorptiometry was performed at baseline and at 1, 6, and 12 mo for each pediatric cancer patient. There were no significant differences in age, sex, body weight, height, body mass index, serum vitamin D levels, BMD, and BMC among children with hematologic malignancies, those with solid tumors, and the controls at baseline. When the medians of BMD Z-scores were compared between different time intervals, whole-body BMD Z-score significantly decreased during the first year of cancer treatment (p = 0.001) in children with hematologic malignancies, especially during the first month (p = 0.002), and between 1 and 6 mo (p = 0.006). In children with solid tumors, whole-body BMD Z-score changed significantly only between 6 and 12 mo after treatment (p = 0.043). Generalized estimation equations for the analysis of trends in the whole-body BMD Z-scores revealed that there were significant downward trends between BMD Z-scores at baseline and those at 12 mo in children with hematologic malignancies and those with solid tumors. Cancer treatment significantly affects the bone health status at least during the first year, causing a significant decrease in BMD, especially during the first 6 mo for patients with hematologic malignancies and during the last 6 mo for those with solid tumors. Better strategies for treating changes in BMD based on the underlying cancer are necessary during cancer treatment in children.

    Data from the Hispanic Health and Nutrition Examination Survey were used to estimate arithmetic mean blood lead and percent with elevated blood lead [25 micrograms per deciliter (micrograms per dl) or greater] for 4-11-year-old Mexican American, Puerto Rican, and Cuban children. The sample size was 1,390 for Mexican American children, 397 for Puerto Rican children, and 114 for Cuban children. Puerto Rican children had the highest mean blood lead levels (11.5 micrograms per dl), followed by Mexican American children (10.4 micrograms per dl) and Cuban children (8.6 micrograms per dl, P less than .05). Puerto Rican children had the highest percent with elevated blood lead (2.7 percent); 1.6 percent of Mexican American children had elevated blood lead; less than 1 percent (0.9 percent) of the Cuban children had elevated blood lead (P less than .05). Mexican American girls had a lower mean blood lead level than did boys: 9.7 micrograms per dl versus 11.0 micrograms per dl (P less than .05). For both Puerto Rican and Mexican American children, younger age indicated a higher risk of having elevated blood lead levels. Mexican American children who lived in poverty had higher mean blood lead levels than did Mexican American children who did not live in poverty--11.6 micrograms per dl versus 9.6 micrograms per dl (P less than .05). Despite advances in primary prevention of lead toxicity in children during the past 10 years, many Hispanic children are at risk of lead toxicity. Approximately 19,000 Mexican American 4-11-year-old children living in the Southwest and approximately 8,000 Puerto Rican children living in the New York City area had elevated blood lead levels (greater than or equal to 25 micrograms per dl) during 1982-84.

    Sarcoma surgeons face unique challenges in younger patients with significant skeletal growth remaining. The heightened concerns regarding radiation in the very young and the drastic changes expected in the lengths and cross-sectional areas of bones affect the decision-making for both soft-tissue and bone sarcomas in this population. Nonetheless, there is sparse literature focused on sarcoma surgery in this age group. The records of one tertiary regional sarcoma treatment program were reviewed to identify all patients ten years old or younger at the time of local control surgery for limb or limb-girdle sarcomas. Demographic information, diagnosis, surgery performed, complications, and general outcomes were gleaned from the medical records. 43 patients were identified, including 15 with osteosarcomas, 11 Ewing’s sarcoma family tumors, five rhabdomyosarcomas, and two synovial sarcomas, among others. Location of tumors varied widely, but demonstrated a predilection for the upper extremity more than is typical in adolescents with the same tumor types. Survival was favorable overall, with only five patients dying from disease. Most patients continued to function well at latest follow-up, but 16 experienced additional surgical interventions following the index procedure. Sarcoma surgery in the younger growing child presents challenges for the surgeon, patient, and parents, but is usually successful in the long-term. PMID:22096434

    We conducted a case-control study of mental retardation (MR) in which case children (aged 10 years) were identified from existing records at multiple sources, primarily the public school systems. Control children were drawn from a roster of public school students not receiving special education services. We found that maternal educational level at the time of delivery was strongly and inversely related to a form of MR not accompanied by other serious neurologic conditions. For this isolated form of MR, maternal educational level was by far the most important predictor from among seven sociodemographic variables examined. There was a significant race-education interaction that indicated a steeper gradient in risk among white mothers than among black mothers. Relative to children of white mothers with 12 years of education, all children of black mothers, except those whose mothers had 16 or more years of education, were at increased risk. The results may be useful as a guide for selecting high-risk groups as candidates for early childhood intervention programs.

    A sample of 90 children with Down's syndrome were measured for recumbent length and weight from birth to age 36 months at the Children's Hospital Medical Center in Boston. At birth, means for both length and weight were reduced by about 0.5 SDs from the control group means. By 36 months, mean recumbent length was greater than 2 SDs below that for the control group, while the mean for weight was reduced by about 1.5 SDs from the control group mean. Growth velocity for both length and weight was most deficient within the first two years of life. About 30% of the sample demonstrated excess weight for length relations by 36 months. Children with moderate or severe heart disease were significantly smaller than those without or with mild cardiac problems at all times after birth. Measurements of a subsample of children at 4, 5, and 6 years of age suggested that growth velocity after 3 years of age may be within the range of normal. Assessment of growth of the child with Down's syndrome may be carried out with reference to charts plotting tenth to 90th percentiles based on these data.

    Purpose: Conformal and intensity modulated radiation therapies have the potential to preserve cognitive outcomes in children with ependymoma; however, functional behavior remains uninvestigated. This longitudinal investigation prospectively examined intelligence quotient (IQ) and adaptive functioning during the first 5 years after irradiation in children diagnosed with ependymoma. Methods and Materials: The study cohort consisted of 123 children with intracranial ependymoma. Mean age at irradiation was 4.60 years (95% confidence interval [CI], 3.85-5.35). Serial neurocognitive evaluations, including an age-appropriate IQ measure and the Vineland Adaptive Behavior Scales (VABS), were completed before irradiation, 6 months after treatment, and annually for 5 years. A total of 579 neurocognitive evaluations were included in these analyses. Results: Baseline IQ and VABS were below normative means (P<.05), although within the average range. Linear mixed models revealed stable IQ and VABS across the follow-up period, except for the VABS Communication Index, which declined significantly (P=.015). Annual change in IQ (-.04 points) did not correlate with annual change in VABS (-.90 to +.44 points). Clinical factors associated with poorer baseline performance (P<.05) included preirradiation chemotherapy, cerebrospinal fluid shunt placement, number and extent of surgical resections, and younger age at treatment. No clinical factors significantly affected the rate of change in scores. Conclusions: Conformal and intensity modulated radiation therapies provided relative sparing of functional outcomes including IQ and adaptive behaviors, even in very young children. Communication skills remained vulnerable and should be the target of preventive and rehabilitative interventions.

    The aim of this study was to select developmentally valid and reliable items for inclusion in criterion-referenced (pass > 90%) posttraumatic amnesia (PTA) scale for children aged 4 to 7 years in a prospective cohort study. Fifty-two typically developing children (26 male/26 female) aged 4 to 7 years were administered a set of 10 items (5 orientation, 5 memory) over 3-4 days. The total score obtained on the set of 10 items had poor developmental validity and test-retest reliability. Nevertheless, individual item analysis identified five items (three orientation and two memory items) that were consistently passed by >90% of the children on each day of testing. For these five items the total scores did not differ significantly either between age groups or between days of testing. Test-retest was extremely high (close to 1). The five items had excellent developmental validity and test-retest reliability. This study identified 5 (3 orientation and 2 memory) items that met our selection criterion and form a new PTA scale, the Sydney PTA scale (SYPTAS), for children aged 4 to 7 years.
