Integrating fundamental movement skills in late childhood

The study examined how children of different ages integrate fundamental movement skills, such as running and throwing, and whether their developmental status was related to the combination of these skills. Thirty children were divided into three groups (G1 = 6-year-olds, G2 = 9-year-olds, and G3 = 12-year-olds) and filmed performing three tasks: running, overarm throwing, and the combined task. Patterns were identified and described, and the efficiency of integration was calculated (distance differences of the ball thrown in two tasks, overarm throwing and combined task). Differences in integration were related to age: the 6-year-olds were less efficient in combining the two skills than the 9- and 12-year-olds. These differences may be indicative of a phase of integrating fundamental movement skills in the developmental sequence. This developmental status, particularly throwing, seems to be related to the competence to integrate skills, which suggests that fundamental movement skills may be developmental modules.

Preditores da realização de consultas odontológicas de rotina e por problema em pré-escolares

OBJETIVO: Estimar a prevalência do uso de serviços odontológicos por pré- escolares e fatores associados. MÉTODOS: Estudo transversal com 1.129 crianças de cinco anos de idade da Coorte de Nascimentos de Pelotas 2004, RS, de setembro de 2009 a janeiro de 2010. Registrou-se o uso de serviço odontológico pelo menos uma vez na vida e o motivo para a primeira consulta odontológica da criança. As categorias do desfecho foram: ter feito a primeira consulta por rotina, para resolver um problema ou nunca ter ido ao dentista. Os exames bucais e as entrevistas foram realizados nos domicílios. Aspectos socioeconômicos e variáveis independentes ligadas à mãe e à criança foram analisados por meio de regressão logística multinomial. RESULTADOS: A prevalência de uso por qualquer motivo foi 37,0%. Os principais preditores para consulta de rotina foram nível econômico mais elevado, mãe com maior escolaridade e ter recebido orientação sobre prevenção. Principais preditores para consulta por problema foram ter sentido dor nos últimos seis meses, mãe com maior escolaridade e ter recebido orientação sobre prevenção. Cerca de 45,0% das mães receberam orientação de como prevenir cárie, principalmente fornecida por dentistas. Filhos de mães com história de maior aderência a programas de saúde tiveram maior probabilidade de ter feito uma consulta odontológica de rotina. CONCLUSÕES: A taxa de utilização dos serviços odontológicos por pré- escolares foi inferior às de consultas médicas (puericultura). Além da renda e da escolaridade, comportamentos maternos têm papel importante no uso por rotina. Relato de dor nos últimos seis meses e número elevado de dentes afetados por cárie, independentemente dos demais fatores, estiveram associados ao uso para resolver problema. É necessária a integração de ações de saúde bucal nos programas materno-infantis.

Questionário sobre dificuldades comunicativas percebidas por pais de crianças do espectro do autismo

OBJETIVO: Elaborar um questionário para o levantamento de dificuldades comunicativas percebidas por pais e/ou cuidadores de crianças do espectro do autismo em relação a seus filhos. MÉTODOS: Os aspectos específicos abordados no questionário foram identificados a partir da literatura e da experiência clínica das autoras em dois serviços especializados. As questões foram organizadas segundo diferentes domínios e as respostas registradas numa escala tipo Likert. Foi realizado um estudo piloto com 40 pais, 20 pais de crianças do espectro do autismo e 20 pais de crianças sem queixas de linguagem, como forma de verificar a aplicabilidade do questionário construído e sua utilidade na identificação de dificuldades específicas da população alvo. Foi calculado o nível de concordância das questões e os resultados dos grupos foram comparados entre si (teste t Student). RESULTADOS: O questionário foi desenvolvido de maneira a abranger aspectos fundamentais para o relacionamento interpessoal, tanto no âmbito comunicativo quanto social. Foi dividido em 24 questões fechadas que abrangem quatro domínios; e uma questão aberta, com espaço para que os pais relatassem algo relevante e que não tenha sido perguntado. O estudo possibilitou testar a compreensão do instrumento e a análise estatística indicou que 19 questões apresentaram diferença. CONCLUSÃO: O questionário elaborado identificou diferenças na percepção e atitude de pais de crianças do espectro do autismo e de crianças sem queixa de linguagem, em relação às dificuldades de comunicação com seus filhos. Dessa forma, mostrou-se útil para o levantamento dessas dificuldades em um grupo maior de indivíduos.

Early malnutrition decreases contrast sensitivity to circular concentric gratings

Early malnutrition refers to inadequate nutrition during the critical period of nervous system development followed by nutritional recovery, resulting in a short stature according to age but normal weight according to short stature. We measured the effects of early malnutrition on contrast sensitivity (CS) to concentric circular gratings in 18 children of both sexes, aged 8 to 11 years (mean = 9.2 years, standard deviation = .99 years). Nine of the children were eutrophic (E group), and nine experienced early malnutrition (EM group) based on state healthcare records and Waterlow's anthropometric parameters. Contrast sensitivity to four spatial frequencies (.25, 1.0, 2.0, and 8.0 cycles per degree [cpd]) was measured using a temporal two-alternative forced-choice psychophysical method with mean luminance of 40.1 cd/m². Statistical analyses showed significant differences between groups and a group × frequency interaction. EM group was significantly less sensitive than the E group to the 8.0 cpd frequency and needed 1.49-times more contrast to detect the gratings. These results suggest that early malnutrition impairs CS to high-spatial-frequency concentric circular gratings in children. Therefore, early malnutrition, which is known to affect primary visual cortical areas, may also affect higher visual cortical areas such as V4 and the inferotemporal cortex.

Optimierung der inhalativen Therapie bei Patienten mit Cystischer Fibrose und bei Kleinkindern

Patienten mit Cystischer Fibrose müssen in der Regel verschiedene Arzneimittel mehrmals täglich inhalieren. Um den hohen Zeitaufwand dafür zu reduzieren werden die Arzneimittel häufig gemischt und simultan inhaliert. Die Kenntnis der physikalisch-chemischen Kompatibilität von Mischinhalationslösungen/ -suspensionen ist deshalb von großer Bedeutung. In der vorliegenden Arbeit wurden die Kompatibilitäten von Mischungen aus Colistimethat-Inhalationslösung (mikrobiologische Wertbestimmung) mit verschiedenen Tobramycin-Inhalationslösungen, Budesonid (HPLC) mit 5,85%-iger Natriumchlorid-Lösung sowie mit Colistimethat-Inhalationslösung und Dornase alfa (SE-HPLC, SDS-PAGE, UV-Spektrometrie, T-SCX-Chromatographie) mit verschiedenen Tobramycin-Inhalationslösungen (Fluoreszenzpolarisations-Immunoassay) nachgewiesen. Durch das Mischen mit Tobramycin-Inhalationslösungen wurden die aerodynamischen Eigenschaften (FPF, MMAD, GSD) von Dornase alfa bei simultaner Verneblung nicht verändert (bestimmt mittels Kaskadenimpaktion).rnDurch die physiologischen und anatomischen Gegebenheiten, sowie die kognitiven Fähigkeiten kleiner Kinder stellt die effektive inhalative Therapie eine große Herausforderung dar. Der Respimat® bietet mit seiner langen Sprühdauer und den kleinen Aerosolpartikeln eine vielversprechende Alternative für die Anwendung bei Kleinkindern. In der vorliegenden Studie wurde untersucht ob bei Kindern unter 5 Jahren der Respimat® als Inhalationsgerät verwendet werden kann und welchen Grad an Hilfestellung sie für ein erfolgreiches Inhalationsmanöver benötigen.rnDie Ergebnisse der Handhabungsuntersuchung, sowie die Bewertung aufgezeichneter Inhalationsprofile zeigten, dass der Respimat® für Kinder < 4 Jahre nur in Kombination mit einer Inhalierhilfe wie dem AeroChamber Plus® verwendet werden sollte. Kinder im Alter von 4 Jahren sind mit entsprechender Schulung in der Lage mit dem Respimat® alleine zu inhalieren.rn

Il child language brokering a Ravenna e provincia: la parola agli studenti e ai professori

The main aim of this study is to provide a description of the phenomenon defined as Child Language Brokering (CLB), a common practice among language minority communities but which has received less attention in the academic literature. As the children of immigrants often learn the host language much more quickly than their parents, they contribute to family life by acting as language and cultural mediators between a family members and different language speakers. Many immigrant families prefer a language broker from within their own family to an external mediator or interpreter, even though there is a well-found resistance to the use of these young interpreters by professionals. In this study I report some findings from surveys of teachers in schools in Ravenna where there has been some use of students as CLBs and of students who have acted or are still acting as mediators for their families in different contexts, not only while at school. This dissertation is divided into five chapters. Chapter one aims at providing an overview of recent migration to Italy and of the differences between first-generation immigrants and second-generation immigrants. The chapter also discusses the available professional interpreting facilities provided by the municipality of Ravenna. Chapter two presents an overview of the literature on child language brokering. Chapter three provides a description of the methodology used in order to analyze the data collected. Chapter four contains a detailed analysis of the questionnaires administered to the students and the interviews submitted to the teachers in four schools in Ravenna. Chapter five focuses on the studies carried out by the researchers of the Thomas Coram Research Unit and University College London and draws a general comparison between their findings from on-line surveys of teachers in schools and my own findings on teachers’ points of view. The results of this study demonstrate that CLB is a common practice among immigrant children living in Ravenna and, although almost all students reported positive appreciation, further work is still needed to assess the impact of this phenomenon.

The polytraumatized or multiply injured child

10.1 In the severely injured infant and child the following age-specific facts should be kept in mind: ■ Larger head to body weight ratio (head often exposed to injury, neck injury) ■ Larger body surface area to body volume ratio (hypothermia) ■ More elastic thoracic wall (internal injury possible without external signs) ■ Thinner abdominal wall where abdominal organs are below the rib cage (liver, spleen injury) ■ Smaller total blood volume ■ Narrow airways ■ Long compensation of blood loss by tachycardia followed by rapid decompensation of circulatory status if left untreated 10.2 Child abuse is frequent: about 3%–7% of children under 18 years suffer from child abuse in some manner. The incidence and prevalence depend on the development of a country’s social service agencies and on the level of health professionals’ awareness of the problem. The estimated number of unreported cases is high. Child abuse affects children of all socioeconomic, ethnic, and religious boundaries. There is no gender preponderance. It occurs at any age, but infants and toddler have a higher risk than older children.

Income Insecurity and Youth Emancipation: A Theoretical Approach

n this paper, we propose a theoretical model to study the effect of income insecurity of parents and offspring on the child's residential choice. Parents are partially altruistic toward their children and will provide financial help to an independent child when her income is low relative to the parents'. We find that children of more altruistic parents are more likely to become independent. However, first-order stochastic dominance (FOSD) shifts in the distribution of the child's future income (or her parents') have ambiguous effects on the child's residential choice. Parental altruism is the very source of ambiguity in the results. If parents are selfish or the joint income distribution of parents and child places no mass on the region where transfers are provided, a FOSD shift in the distribution of the child's (parents') future income will reduce (raise) the child's current income threshold for independence.

Reference photographs for nasolabial appearance rating in unilateral cleft lip and palate

A popular method for nasolabial rating in unilateral cleft lip and palate (UCLP) is the Asher-McDade system consisting of a 5-point ordinal scale assessing nasal form, nasal symmetry, nasal profile, and vermilion border. The aim of the current study was to identify reference photographs illustrating this scale to facilitate its use.Four observers assessed nasolabial appearance on frontal and profile photographs of the nasolabial area of 42 children of Caucasian origin with a repaired UCLP at age 9 years. Cronbachs alpha, based on the individual scores of the 4 observers, ranged from 0.73 to 0.82 for the 4 nasolabial ratings, indicating a good reliability. The reliability of the overall score (mean of the 4 component scores) was also high (Cronbachs alpha, 0.83). Both for the nasolabial component ratings and for the overall score, duplicate measurement errors were small. The reliability for the mean of the 4 observers' scores was good, Spearman rank correlation coefficients ranging from 0.56 to 0.96.Subsequently, photographs were selected that showed the highest agreement among observers. For each of the 4 components (eg, nasal form, nasal deviation, nasal profile, and shape of the vermilion border), 5 photographs were selected to illustrate the whole range of the scale (score, 1-5), resulting in the selection of 20 pictures.It was concluded that nasolabial appearance rating can be performed reliably using a panel of judges and averaging the scores of all observers. Reference photographs, as developed from this study, may facilitate the rating task.

Construction Grammar For Kids

Most accounts of child language acquisition use as analytic tools adult-like syntactic categories and schemas (formal grammars) with little concern for whether they are psychologically real for young children. Recent research has demonstrated, however, that children do not operate initially with such abstract linguistic entities, but instead operate on the basis of concrete, item-based constructions. Children construct more abstract linguistic constructions only gradually – on the basis of linguistic experience in which frequency plays a key role – and they constrain these constructions to their appropriate ranges of use only gradually as well – again on the basis of linguistic experience in which frequency plays a key role. The best account of first language acquisition is provided by a construction-based, usage-based model in which children process the language they experience in discourse interactions with other persons, relying explicitly and exclusively on social and cognitive skills that children of this age are known to possess.

Mice generated by in vitro fertilization exhibit vascular dysfunction and shortened life span

Children conceived by assisted reproductive technologies (ART) display a level of vascular dysfunction similar to that seen in children of mothers with preeclamspia. The long-term consequences of ART-associated vascular disorders are unknown and difficult to investigate in healthy children. Here, we found that vasculature from mice generated by ART display endothelial dysfunction and increased stiffness, which translated into arterial hypertension in vivo. Progeny of male ART mice also exhibited vascular dysfunction, suggesting underlying epigenetic modifications. ART mice had altered methylation at the promoter of the gene encoding eNOS in the aorta, which correlated with decreased vascular eNOS expression and NO synthesis. Administration of a deacetylase inhibitor to ART mice normalized vascular gene methylation and function and resulted in progeny without vascular dysfunction. The induction of ART-associated vascular and epigenetic alterations appeared to be related to the embryo environment; these alterations were possibly facilitated by the hormonally stimulated ovulation accompanying ART. Finally, ART mice challenged with a high-fat diet had roughly a 25% shorter life span compared with control animals. This study highlights the potential of ART to induce vascular dysfunction and shorten life span and suggests that epigenetic alterations contribute to these problems.

Maternal cholestasis during pregnancy programs metabolic disease in offspring

The intrauterine environment is a major contributor to increased rates of metabolic disease in adults. Intrahepatic cholestasis of pregnancy (ICP) is a liver disease of pregnancy that affects 0.5%-2% of pregnant women and is characterized by increased bile acid levels in the maternal serum. The influence of ICP on the metabolic health of offspring is unknown. We analyzed the Northern Finland birth cohort 1985-1986 database and found that 16-year-old children of mothers with ICP had altered lipid profiles. Males had increased BMI, and females exhibited increased waist and hip girth compared with the offspring of uncomplicated pregnancies. We further investigated the effect of maternal cholestasis on the metabolism of adult offspring in the mouse. Females from cholestatic mothers developed a severe obese, diabetic phenotype with hepatosteatosis following a Western diet, whereas matched mice not exposed to cholestasis in utero did not. Female littermates were susceptible to metabolic disease before dietary challenge. Human and mouse studies showed an accumulation of lipids in the fetoplacental unit and increased transplacental cholesterol transport in cholestatic pregnancy. We believe this is the first report showing that cholestatic pregnancy in the absence of altered maternal BMI or diabetes can program metabolic disease in the offspring.

Kognitive Basisfunktionen und motorisch-koordinative Kompetenzen in Abhängigkeit des Peerstatus bei Kindern zu Beginn der Schulzeit

Zusammenfassung. In der vorliegenden Studie wird der Frage nachgegangen, ob sich zwischen beliebten, durchschnittlichen, unbeachteten und zurückgewiesenen Kindern Unterschiede in spezifischen kognitiven und motorischen Fähigkeiten finden lassen. Zu drei verschiedenen Zeitpunkten wurden mit 177 regulär eingeschulten 7-jährigen Kindern Peernominationen und Peerratings erhoben, um reliable soziometrische Daten zu erhalten und ein Vergleich der beiden Methoden vorzunehmen. Außerdem wurde eine umfassende Testbatterie von insgesamt 20 Aufgaben in den Bereichen Informationsverarbeitungsgeschwindigkeit, Kurzzeit- und Arbeitsgedächtnis, Inhibition, Sprache und Motorik durchgeführt. Mit Ausnahme der Kurzzeitgedächtniskapazität wurden für alle Funktionsbereiche signifikante Unterschiede zwischen den Statusgruppen gefunden. Die kontinuierlichen soziometrischen Werte der Ratingmethode zeigten sich etwas sensitiver als die der Nominationsmethode. Korrelativ wurde mit beiden Methoden ersichtlich, dass bessere Leistungen im kognitiven und motorischen Bereich nicht nur mit mehr Beliebtheit zusammenhingen, sondern auch, dass schlechte Leistungen in Verbindung standen mit sozialer Zurückweisung. Abstract. In the present study, it was investigated whether popular, average, neglected, and rejected children differ with respect to specific cognitive and motor skills. Peer nomination and peer rating methods were used at three different points in time to obtain reliable sociometric data of 177 regularly enrolled 7-year-old children and to compare the two methods. Furthermore, a battery comprising 21 tasks was used to assess speed of information processing, short-term and working memory, inhibition, language, and motor skills. Significant differences were found between children of different status groups with respect to all studied abilities with the exception of short-term memory. The continuous sociometric scores of the rating method resulted to be slightly more sensitive than those obtained with the nomination method. However, correlative analyses with both methods showed that better performance on the cognitive and motor tasks was associated with popularity, whereas worse performance was related to social rejection.

Decrease in pneumococcal co-colonization following vaccination with the seven-valent pneumococcal conjugate vaccine.

Understanding the epidemiology of pneumococcal co-colonization is important for monitoring vaccine effectiveness and the occurrence of horizontal gene transfer between pneumococcal strains. In this study we aimed to evaluate the impact of the seven-valent pneumococcal conjugate vaccine (PCV7) on pneumococcal co-colonization among Portuguese children. Nasopharyngeal samples from children up to 6 years old yielding a pneumococcal culture were clustered into three groups: pre-vaccine era (n = 173), unvaccinated children of the vaccine era (n = 169), and fully vaccinated children (4 doses; n = 150). Co-colonization, serotype identification, and relative serotype abundance were detected by analysis of DNA of the total bacterial growth of the primary culture plate using the plyNCR-RFLP method and a molecular serotyping microarray-based strategy. The plyNCR-RFLP method detected an overall co-colonization rate of 20.1%. Microarray analysis confirmed the plyNCR-RFLP results. Vaccination status was the only factor found to be significantly associated with co-colonization: co-colonization rates were significantly lower (p = 0.004; Fisher's exact test) among fully vaccinated children (8.0%) than among children from the pre-PCV7 era (17.3%) or unvaccinated children of the PCV7 era (18.3%). In the PCV7 era there were significantly less non-vaccine type (NVT) co-colonization events than would be expected based on the NVT distribution observed in the pre-PCV7 era (p = 0.024). In conclusion, vaccination with PCV7 resulted in a lower co-colonization rate due to an asymmetric distribution between NVTs found in single and co-colonized samples. We propose that some NVTs prevalent in the PCV7 era are more competitive than others, hampering their co-existence in the same niche. This result may have important implications since a decrease in co-colonization events is expected to translate in decreased opportunities for horizontal gene transfer, hindering pneumococcal evolution events such as acquisition of antibiotic resistance determinants or capsular switch. This might represent a novel potential benefit of conjugate vaccines.
