    Maintaining social order requires the policing of transgressions. Prior research suggests that policing emerges early in life, but little is known about children's engagement in such behavior in live interactions where there is uncertainty about the consequences. In this study, 4- to 11-year-old children (N=158) witnessed an unfamiliar adult confederate intentionally destroy another adult's property. Of interest was whether children would engage in policing behavior by protesting to the transgressor or by spontaneously reporting the transgression to a third party. Some children engaged in these behaviors spontaneously; nearly half (42%) protested the transgression, and 27% reported it without being prompted. Even when children did not spontaneously report the transgression, they almost always reported it when asked directly. The findings show that children commonly engage in policing even in the face of potentially negative consequences. PMID:27295206

    We investigated the effect of young children's (hereafter children's) facial expressions on adult responsiveness. In Study 1, 131 undergraduate students from a midsized university in the midwestern United States rated children's images and videos with smiling, crying, or neutral expressions on cuteness, likelihood to adopt, and participants' experienced distress. Looking times at images and videos along with perception of cuteness, likelihood to adopt, and experienced distress using 10-point Likert scales were measured. Videos of smiling children were rated as cuter and more likely to be adopted and were viewed for longer times compared with videos of crying children, which evoked more distress. In Study 2, we recorded responses from 101 of the same participants in an online survey measuring gender role identity, empathy, and perspective taking. Higher levels of femininity (as measured by Bem's Sex Role Inventory) predicted higher "likely to adopt" ratings for crying images. These findings indicate that adult perception of children and motivation to nurture are affected by both children's facial expressions and adult characteristics and build on existing literature to demonstrate that children may use expressions to manipulate the motivations of even non-kin adults to direct attention toward and perhaps nurture young children.

  3. Cough: are children really different to adults?

    OpenAIRE

    Chang, Anne B

    2005-01-01

    Worldwide paediatricians advocate that children should be managed differently from adults. In this article, similarities and differences between children and adults related to cough are presented. Physiologically, the cough pathway is closely linked to the control of breathing (the central respiratory pattern generator). As respiratory control and associated reflexes undergo a maturation process, it is expected that the cough would likewise undergo developmental stages as well. Clinically, th...

    Full Text Available Adult mortality due to HIV/AIDS and other diseases is posited to affect children through a number of pathways. On top of health and education outcomes, adult mortality can have significant effects on children by influencing demographic outcomes including the timing of marriage. This paper examines marriage outcomes for a sample of children interviewed in Tanzania in the early 1990s and re-interviewed in 2004. We find that while girls who became paternal orphans married at significantly younger ages, orphanhood had little effect on boys. On the other hand, non-parental deaths in the household affect the timing of marriage for boys.

    2005-11-01

    Full Text Available Abstract Background Pulmonary alveolar proteinosis (PAP is a rare disease, characterized by excessive intra-alveolar accumulation of surfactant lipids and proteins. Therapeutic whole lung lavages are currently the principle therapeutic option in adults. Not much is known on the kinetics of the wash out process, especially in children. Methods In 4 pediatric and 6 adult PAP patients 45 therapeutic half lung lavages were investigated retrospectively. Total protein, protein concentration and, in one child with a surfactant protein C mutation, aberrant pro-SP-C protein, were determined during wash out. Results The removal of protein from the lungs followed an exponential decline and averaged for adult patients 2 – 20 g and Conclusion Following therapeutic half lung lavages by biochemical variables may help to estimate the degree of alveolar filling with proteinaceous material and to improve the efficiency of the wash out, especially in children.

    Fogel, Alan

    Current cultural attitudes toward children's sexuality resemble attitudes toward adults' sexuality; there is an emphasis on purely genital and orgasmic pleasure. Adults and children need warmth, physical contact, and a sense of belonging for which genital stimulation may be unnecessary or inappropriate. Children's sexual advances to adults, as…

  11. [Pneumococcal vaccination for children and adults].

    Albrich, Werner

    2016-01-01

    Pneumococci are the leading bacterial causes of respiratory tract infections, bacteremia and meningitis. Pneumococcal conjugate vaccines (PCV) are effective and safe in young children. Their introduction led to significant reductions of invasive pneumococcal disease (IPD), pneumonia, otitis media and antibiotic-resistant pneumococcal infections. Beyond these effects in the vaccinated age groups, there is a reduction in nasopharyngeal pneumococcal carriage and therefore in transmission. This in turn led to marked reductions in IPD and pneumonia in non-vaccinated age groups, particularly elderly adults as evidence of herd protection. Recently it was shown that the 13-valent PCV13 is effective and safe in adults leading to the age-independent recommendation of PCV13 in all persons with risk factors. PMID:27268445

  19. Parental divorce and adult children's attachment representations and marital status.

    Science.gov (United States)

    Crowell, Judith A; Treboux, Dominique; Brockmeyer, Susan

    2009-01-01

    The purpose of this study was to explore adult attachment as a means of understanding the intergenerational transmission of divorce, that is, the propensity for the children of divorce to end their own marriages. Participants included 157 couples assessed 3 months prior to their weddings and 6 years later. Participants completed the Adult Attachment Interview and questionnaires about their relationships, and were videotaped with their partners in a couple interaction task. Results indicated that, in this sample, adult children of divorce were not more likely to divorce within the first 6 years of marriage. However, parental divorce increased the likelihood of having an insecure adult attachment status. For women, age at the time of their parents' divorce was related to adult attachment status, and the influence on attachment representations may be more enduring. Among adult children of divorce, those who were classified as secure in their attachment representations were less likely to divorce in the early years of marriage than insecure participants.

  20. Adult Children's Education and Parents' Functional Limitations in Mexico.

    Science.gov (United States)

    Yahirun, Jenjira J; Sheehan, Connor M; Hayward, Mark D

    2016-04-01

    This article asks how adult children's education influences older parents' physical health in Mexico, a context where older adults often lack access to institutional resources and rely on kin, primarily children, as a main source of support. Using logistic and negative binomial regression models and data from the first wave of the Mexican Health and Aging Study (N = 9,661), we find that parents whose children all completed high school are less likely to report any functional limitations as well as fewer limitations compared to parents with no children who completed high school. This association remains significant even after accounting for parent and offspring-level characteristics, including parents' income that accounts for children's financial transfers to parents. Future research should aim to understand the mechanisms that explain the association between adult children's education and changes to parents' health over time. PMID:26966254

  1. Treatment of the common cold in children and adults.

    The common cold, or upper respiratory tract infection, is one of the leading reasons for physician visits. Generally caused by viruses, the common cold is treated symptomatically. Antibiotics are not effective in children or adults. In children, there is a potential for harm and no benefits with over-the-counter cough and cold medications; therefore, they should not be used in children younger than four years. Other commonly used medications, such as inhaled corticosteroids, oral prednisolone, and Echinacea, also are ineffective in children. Products that improve symptoms in children include vapor rub, zinc sulfate, Pelargonium sidoides (geranium) extract, and buckwheat honey. Prophylactic probiotics, zinc sulfate, nasal saline irrigation, and the herbal preparation Chizukit reduce the incidence of colds in children. For adults, antihistamines, intranasal corticosteroids, codeine, nasal saline irrigation, Echinacea angustifolia preparations, and steam inhalation are ineffective at relieving cold symptoms. Pseudoephedrine, phenylephrine, inhaled ipratropium, and zinc (acetate or gluconate) modestly reduce the severity and duration of symptoms for adults. Nonsteroidal anti-inflammatory drugs and some herbal preparations, including Echinacea purpurea, improve symptoms in adults. Prophylactic use of garlic may decrease the frequency of colds in adults, but has no effect on duration of symptoms. Hand hygiene reduces the spread of viruses that cause cold illnesses. Prophylactic vitamin C modestly reduces cold symptom duration in adults and children. PMID:22962927

    Sleep is an important modulator of neuroendocrine function and glucose metabolism in children as well as in adults. In recent years, sleep curtailment has become a hallmark of modern society with both children and adults having shorter bedtimes than a few decades ago. This trend for shorter sleep duration has developed over the same time period as the dramatic increase in the prevalence of obesity. There is rapidly accumulating evidence from both laboratory and epidemiological studies to indi...

    2010-03-01

    Interstitial lung diseases (ILDs) occur across the lifespan, from birth to advanced age. However, the causes, clinical manifestations, histopathology, and management of ILD differ greatly among infants, older children, and adults. The historical approach of classifying childhood ILD (chILD) using adult classification schemes may therefore have done more harm than good. Nevertheless, identification of novel forms of chILD in the past decade, such as surfactant metabolism dysfunction disorders and neuroendocrine cell hyperplasia of infancy (NEHI), as well as genomic analysis of adult ILDs, has taught us that identical genotypes may result in distinct phenotypes at different ages and developmental stages, and that lung developmental pathways and cellular phenotypes are often recapitulated in adult ILDs. Thus comparison of the pathophysiology of ILD in children and adults in the context of lung development is useful in understanding the pathogenesis of these disorders, and may lead to novel therapeutic interventions for ILDs at all ages.

  14. Developmental reversals in recognition memory in children and adults.

    Science.gov (United States)

    Gross, Julien; Gardiner, Beatrix; Hayne, Harlene

    2016-01-01

    Older members of a given species typically exhibit superior learning and memory abilities relative to younger members, however, the developmental difference does not always occur in this younger-to-older direction. Developmental reversals are thought to reflect adaptive responses to the unique challenges imposed by the infant's niche. In humans, identification of developmental reversals has largely been precluded because infants, children, and adults are rarely tested using the same experimental procedures. Here, we adapted the visual recognition memory task and tested 3-year-olds and adults using one set of child-oriented stimuli and one set of adult-orientated stimuli. When tested immediately, children and adults exhibited recognition memory for both stimuli. When tested after a 1-week delay, children exhibited recognition memory for the child-oriented stimuli, but not for the adult-oriented stimuli and adults exhibited recognition memory for the adult-oriented stimuli, but not for the child-oriented stimuli. These data have important implications for current theories of memory development.

    Science.gov (United States)

    Rische, Jacquelyn L; Komarova, Natalia L

    2016-02-01

    The fascinating ability of humans to modify the linguistic input and "create" a language has been widely discussed. In the work of Newport and colleagues, it has been demonstrated that both children and adults have some ability to process inconsistent linguistic input and "improve" it by making it more consistent. In Hudson Kam and Newport (2009), artificial miniature language acquisition from an inconsistent source was studied. It was shown that (i) children are better at language regularization than adults and that (ii) adults can also regularize, depending on the structure of the input. In this paper we create a learning algorithm of the reinforcement-learning type, which exhibits patterns reported in Hudson Kam and Newport (2009) and suggests a way to explain them. It turns out that in order to capture the differences between children's and adults' learning patterns, we need to introduce a certain asymmetry in the learning algorithm. Namely, we have to assume that the reaction of the learners differs depending on whether or not the source's input coincides with the learner's internal hypothesis. We interpret this result in the context of a different reaction of children and adults to implicit, expectation-based evidence, positive or negative. We propose that a possible mechanism that contributes to the children's ability to regularize an inconsistent input is related to their heightened sensitivity to positive evidence rather than the (implicit) negative evidence. In our model, regularization comes naturally as a consequence of a stronger reaction of the children to evidence supporting their preferred hypothesis. In adults, their ability to adequately process implicit negative evidence prevents them from regularizing the inconsistent input, resulting in a weaker degree of regularization. PMID:26580218

    This article addresses a question that was a topic of debate in the middle decades of the 20th century but was then abandoned as interest in children's learning declined. The question is, does learning develop? In other words, does the learning process itself undergo age-related change, or does it remain invariant ontogenetically and…

    Influential theories on moral judgments propose that they rely either on emotions or on innate moral principles. In contrast, the mental model theory postulates that moral judgments rely on reasoning, either intuition or deliberation. The theory allows for the possibility that intuitions lead to utilitarian judgments. This paper reports two experiments involving fifth-grade children, adolescents, and adults; the results revealed that children reason intuitively to resolve moral dilemmas in which action and inaction lead to different outcomes. In particular, the results showed female children to be more utilitarian than female adults in resolving classical moral dilemmas: they preferred an action that achieved a good outcome for a greater number of people. Within the mental model theory's framework there is no reason to expect that females and males differ in their ability to reason, but at the moment the results for females cannot be generalized to males who were not properly represented in the adults groups of the two experiments. The result revealing that (female) children are more utilitarian than (female) adults, which is hard to explain via many current theories, was predicted by the mental model theory. PMID:26441722

    Observation that children`s fingerprints disappear from surfaces more quickly than adults`, initiated a study to characterize the chemical components in fingerprints. Samples were obtained from about 50 individuals ranging in age from 3 to 64 by extracting chemicals from the fingertips using rubbing alcohol. Using combined gas chromatography/mass spectrometry, a wide range of compounds were identified. Samples from children contained higher levels of relatively volatile free fatty acids, while those from adults had higher levels of less volatile long chain esters of fatty acids. These esters are thought to originate from sebaceous glands located on the face and levels of these compounds increase substantially after puberty. Also, other compounds were observed that could be used to develop improved methods for fingerprint detection at a crime scene. Further, observation of specific compounds raises the possibility of being able to identify personal traits (gender, habits, diseases, etc. ) via analysis of components in fingerprints and/or skin.

    Background Pharmacogenetic testing may change clinical medicine by allowing clinicians to tailor medications based on a patient’s genetic makeup, however, these tests must first be validated in large, real-life populations of subjects that include children. A dearth of knowledge exists for whether pediatric populations are as willing as adult populations to provide samples for such studies. Objective (1) To assess whether pediatric and adult patients with persistent asthma are willing to provide specimens for DNA extraction and genetic studies. (2) To assess whether patients’ willingness to provide blood as compared to buccal smear specimens differ. Methods Of 644 patients ages 4–38 years who had three or more prescription fills for inhaled corticosteroids in one year, 60% (385) were randomized to the blood specimen group and 40% (259) were randomized to the buccal smear group in order to study acceptance of different biospecimen collection methods. Research assistants contacted subjects to obtain consent, perform a phone survey, and request a specimen. Results There were no baseline differences between subjects randomized to the blood specimen group versus buccal smear group with respect to age, gender, or number of dispensings of inhaled corticosteroids. Of 259 subjects in the buccal smear group, 30% (78) provided samples, and of 385 subjects in the blood specimen group, 16% (60) provided samples. Subjects randomized to the buccal smear group were more likely to provide specimens for genetic study compared to subjects randomized to the blood specimen group (RR 1.21; 95% CI 1.10 – 1.32), even after adjusting for age. Pediatric subjects were more likely to provide specimens for genetic study than adult subjects with 23% (113) of pediatric subjects providing samples and 15% (25) of adult subjects providing samples (p=0.03). Conclusion Children with asthma are as likely to participate in genetic studies as adults. Both children and adult subjects are more

    Child maltreatment cases often hinge on a child's word versus a defendant's word, making children's disclosures crucially important. There is considerable debate concerning why children recant allegations, and it is imperative to examine recantation experimentally. The purpose of this laboratory analogue investigation was to test (a) how often children recant true allegations of an adult's wrongdoing after disclosing and (b) whether children's age and caregiver supportiveness predict recantation. During an interactive event, 6- to 9-year-olds witnessed an experimenter break a puppet and were asked to keep the transgression a secret. Children were then interviewed to elicit a disclosure of the transgression. Mothers were randomly assigned to react supportively or unsupportively to this disclosure, and children were interviewed again. We coded children's recantations (explicit denials of the broken puppet after disclosing) and changes in their forthcomingness (shifts from denial or claims of lack of knowledge/memory to disclosure and vice versa) in free recall and in response to focused questions about the transgression. Overall, 23.3% of the children recanted their prior disclosures (46% and 0% in the unsupportive and supportive conditions, respectively). No age differences in recantation rates emerged, but 8- and 9-year-olds were more likely than 6- and 7-year-olds to maintain their recantation throughout Interview 2. Children whose mothers reacted supportively to disclosure became more forthcoming in Interview 2, and those whose mothers reacted unsupportively became less forthcoming. Results advance theoretical understanding of how children disclose negative experiences, including sociomotivational influences on their reports, and have practical implications for the legal system.

    1987-03-01

    The relationship between certain features of adult speech and autistic children's response adequacy was examined within the context of unstructured, dyadic conversations. On separate sessions, four verbal, nonecholalic children were observed talking with their mothers and teachers. Analysis of conversational turns showed that as the number of facilitating features contained in adults' eliciting utterances increased, the proportion of adequate replies from the children increased. In this analysis, facilitating features included the use of Yes/No questions, questions that were conceptually simple, and questions that were semantically contingent on the child's topic. In a further analysis, it was found that adults tended to modify their use of these features in response to child feedback, although this tendency was relatively small and observed only in a minority of the sequences evaluated. The findings are discussed in terms of pragmatic deficits associated with autism and implications for intervention with this population. PMID:3571145

    The large impact of loss of reward on behavior has been well documented in adult populations. However, whether responsiveness to loss relative to gain is similarly elevated in child versus adult populations remains unclear. It is also unclear whether relations between incentive behaviors and self-reported reward/punishment sensitivity are similar within different developmental stages. To investigate these questions, 7- to 10-year-old children (N = 70) and young adults (N = 70) completed the Behavioral Inhibition System/Behavioral Activation System (BIS/BAS) scale, along with 2 probabilistic incentive tasks assessing gain approach and loss avoidance behavior. BIS/BAS subscales were calculated per Pagliaccio et al. (2015), which established an age invariant model of the BIS/BAS. Bias toward responses more frequently followed by gain feedback and away from responses more frequently followed by loss feedback, approach, and avoidance behavior, respectively, were quantified via signal detection statistics. Gain approach behavior did not differ across age groups; however, children exhibited significantly elevated loss avoidance relative to adults. Children also showed greater reductions in accuracy and slower RTs specifically following loss feedback relative to adults. Interestingly, despite age group differences in loss avoidance behavior, relations between self-report measures and approach/avoidance behaviors were similar across age groups. Participants reporting elevated motivation (BAS Drive) showed both elevated gain approach and elevated loss avoidance, with both types of behavior predicting unique variance in BAS Drive. Results highlight the often-neglected developmental and motivational roles of responsiveness to loss of reward. PMID:26524484

    We used an immersive virtual environment to examine how children and adults learn to intercept moving gaps and whether children and adults benefit from variability of practice. Children (10- and 12-year-olds) and adults attempted to bicycle between two moving vehicle-size blocks without stopping. In Experiment 1, block motions were timed such that if participants maintained a constant speed, they would intercept the gap between the blocks. By the last set of intersections, adults learned to maintain a constant speed throughout the approach to the intersection, 12-year-olds exhibited less variability in time-to-spare when they intercepted the blocks, and 10-year-olds exhibited no significant change across intersection sets. In Experiment 2, block motions during the first eight intersections were timed such that participants needed to either speed up or slow down on all intersections or needed to speed up on half and slow down on half of the intersections. On the last four intersections, all age groups encountered a novel block timing in which no adjustment in speed was necessary to intercept the blocks. The adults performed well regardless of whether they experienced consistent or variable block timings. The 10-year-olds in the variable condition performed better on slow-down trials than their peers in the slow-down condition but performed worse on speed-up trials than their peers in the speed-up condition. Discussion focuses on possible developmental changes in reliance on perceptually available and remembered information in complex perception-action tasks. PMID:24576506

    1986-10-01

    Live attenuated varicella vaccine has been administered to 307 children with leukemia in remission and to 86 healthy adults. The vaccine was well tolerated and immunogenic. The major side effect in leukemic children receiving maintenance chemotherapy was development of a vaccine-associated rash. Vaccinees in whom a rash developed were potentially somewhat infectious to others about 1 month after immunization. Vaccination was not associated with an increase in the incidence of herpes zoster or in relapse of leukemia. Vaccination provided excellent protection against severe varicella. It was associated with a significant decrease in the attack rate of chickenpox following an intimate exposure to varicella-zoster virus, conferring about 80% protection in leukemic children. The cases of breakthrough varicella that occurred were mild. Thus, the vaccine may either prevent or modify varicella in high-risk individuals. It may also have use for prevention of nosocomial varicella.

    This chapter examines how 2-year-old children attempt to actively participate in adult work in a Mayan community in Chiapas, Mexico, and how adults contribute and accommodate to the contributions. As children enter into activities and adults orient and reorient the activity to direct the children, teaching from expert to novice is generated by children's agency in co-participatory interactions. The chapter enriches the LOPI model by focusing on the structure of participation and communication, social and community organization, and the evaluation that occurs in the activity itself.

  3. Estimation of uranium GI absorption fractions for children and adults

    International Nuclear Information System (INIS)

    Uranium is ubiquitously found in drinking water and food. The gastrointestinal tract absorption fraction (f1) is an important parameter in risk assessment of uranium burdens from ingestion. Although absorption of uranium from ingestion has been studied extensively in the past, human data concerning children and adults are still limited. In a previous study based on measurements of uranium concentration in 73 bone-ash samples collected by Health Canada, the absorption fractions for uranium ingestion were determined to be 0.093 ± 0.113 for infants, and 0.050 ± 0.032 for young children ranging from 1 to 7 y of age. To extend the study, a total of 69 bone-ash samples were selected for children and adults ranging from 7 to 25 y of age and residing in the same Canadian community that is known to have an elevated level of uranium in its drinking water supply. For each bone-ash sample, the total uranium concentration was measured by inductively coupled plasma mass spectrometry. To solve uranium transfer in the biokinetic model for uranium given in International Commission of Radiological Protection (ICRP) Publication 69 with estimated daily uranium intake, the program WinSAAM v3.0.1 was used. The absorption fractions were determined to be 0.030 ± 0.022 for children (7-18 y) and 0.021 ± 0.015 for adults (18-25 y). For anyone more than 18 y of age, the estimated f1 value for uranium agree well with the ICRP recommended value of 0.02. Published by Oxford Univ. Press on behalf of the Canadian Government 2010.

    Among the long-term complications of Classic Galactosaemia (Gal) is premature ovarian insufficiency (POI) in female patients with subtle abnormalities of reproductive function also reported in male patients. Leptin is a circulating hormone which reflects body energy stores and which affects the neuroendocrine reproductive axis and pubertal development.We measured serum leptin in 28 children (10 girls, 18 boys; mean age 7.6 years, range 0.5-17.9 years) and in 22 adults (10 females, 12 males; mean age 23.9 years, range 18-37 years) with Gal on a strict galactose-restricted diet in comparison with control data.Leptin levels (expressed as SDS for gender and pubertal stage) were lower in Gal children than controls (mean leptin-SDS = -0.71 for girls, p < 0.05, -0.97 for boys compared with SDS = 0 for controls, p < 0.05). In an age-related analysis, leptin levels did not correlate with age in children with Gal for both sexes as it did for matched controls.As expected, females had higher leptin levels than males in either group. In adults with Gal, leptin concentrations were within normal limits for both sexes when adjusted for gender and BMI. There was a linear relationship between log-leptin and BMI in children with Gal and in controls. For Gal women, log-leptin was also associated with BMI. However, for Gal men, and hence for the entire group of adult Gal patients, this association between log-leptin and BMI was not detectable. Our findings suggest that leptin dysregulation may play a role in fertility issues in individuals with Gal from an early age.

    Urinary growth hormone (u-GH) excretion was measured in 547 healthy children and 110 adults by ELISA with a detection limit of 1.1 ng/l u-GH after prior concentration of the urine samples (20- to 30-fold). u-GH excretion values were significantly dependent on the pubertal stage (p less than 0.......0001) with maximum values in Tanner stage 3 for girls and 4 for boys. This corresponded to a peak in u-GH excretion between 11.5-14.5 years in girls and 12.5-16 years in boys. Additionally, u-GH excretion in adults was significantly higher than in prepubertal children (p less than 0.001). The day/night ratio...... of u-GH excretion (pg/h) was significantly higher in females than in males (p less than 0.01). In Tanner stages 1-4, u-GH excretion during the day was lower than that at night, whereas the opposite was true in late puberty and in adult women. The interindividual variation of u-GH excretion within the...

    1986-05-01

    A frequent complaint of facially deformed people is that they are rejected by others. This study was designed to examine whether negative reactions to facially deformed people would be demonstrated by girls and boys aged 5-11 years. The children were asked to attribute positive or negative characteristics to photographs in which adults were shown before and after minor oral surgery. Despite the relatively small differences in appearance between each adult's before- and after-operation photographs, it was found that, whereas overall the younger children selected faces at around chance level (i.e. 50 per cent), the 11-year-olds on 75 per cent of occasions selected in response to questions concerning friendliness and helping (deemed 'positive') the after-operation photographs, and in response to questions concerning fear and anger (deemed 'negative') the before-operation photographs. When the children's own judgements of facial attractiveness were related to the faces they had chosen in response to positive and negative questions, while again for the five-year-olds only chance responding (50 per cent) was observed, by age seven 75 per cent, and by age 11 90 per cent, of choices suggested facial stereotyping.

  7. Representation of Multiple Durations in Children and Adults

    2011-01-01

    Full Text Available Keeping track of durations of multiple event attributes with different onset and offset times is a challenging task for both children and adults. In this study, children between 5 and 15 years and young adults observed a puppet show in which three puppets appeared on the scene during overlapping intervals of 30 s to 90 s. At test, participants completed a conventional time estimation task and a timeline task in which they reconstructed the temporal pattern by drawing a timeline for each puppet. For all age groups, the timeline task produced more accurate duration judgments than the time estimation task. Preschoolers’ time estimation was at chance level, but their timeline performance was surprisingly good and age differences were eliminated in some task conditions. These findings suggest that the timeline procedure provides an efficient retrieval support for complex temporal events and that even preschool-aged children are able to represent multiple asynchronous durations, possibly by relying on relational event knowledge in combination with visuospatial retrieval support.

    Recent research has shown that memory illusions can successfully prime both children's and adults' performance on complex, insight-based problems (compound remote associates tasks or CRATs). The current research aimed to clarify the locus of these priming effects. Like before, Deese-Roediger-McDermott (DRM) lists were selected to prime subsequent CRATs such that the critical lures were also the solution words to a subset of the CRATs participants attempted to solve. Unique to the present research, recognition memory tests were used and participants were either primed during the list study phase, during the memory test phase, or both. Across two experiments, primed problems were solved more frequently and significantly faster than unprimed problems. Moreover, when participants were primed during the list study phase, subsequent solution times and rates were considerably superior to those produced by those participants who were simply primed at test. Together, these are the first results to show that false-memory priming during encoding facilitates problem-solving in both children and adults. PMID:26230151

    Full Text Available Fluid reasoning, or the capacity to think logically and solve novel problems, is central to the development of human cognition, but little is known about the underlying neural changes. During the acquisition of event-related fMRI data, children aged 6-13 (N = 16 and young adults (N = 17 performed a task in which they were asked to identify semantic relationships between drawings of common objects. On semantic problems, participants indicated which of fi ve objects was most closely semantically related to a cued object. On analogy problems, participants solved a visual propositional analogy (e.g., shoe is to foot as glove is to…µ by indicating which of four objects would complete the problem; these problems required integration of two semantic relations, or relational integration. Our prior research on analogical reasoning in adults implicated left anterior ventrolateral prefrontal cortex (VLPFC in the controlled retrieval of individual semantic relationships, and rostrolateral prefrontal cortex (RLPFC in relational integration. In this study, age-related changes in the recruitment of VLPFC, temporal cortex, and other cortical regions were observed during the retrieval of individual semantic relations. In contrast, agerelated changes in RLPFC function were observed during relational integration. Children aged 6-13 engage RLPFC too late in the analogy trials to infl uence their behavioral responses, suggesting that important changes in RLPFC function take place during adolescence.

    Severe asthma at all ages is heterogeneous incorporating several phenotypes that are distinct in children and adults, however, there are also numerous similar features including the limitation that they may not remain stable longitudinally. Severe asthma in both children and adults is characterized by eosinophilic airway inflammation and evidence of airway remodeling. In adults, targeting eosinophilia with anti-IL-5 antibody therapy is very successful, resulting in the recommendation that sputum eosinophils should be used to guide treatment. In contrast, data for the efficacy of blocking IL-5 remain unavailable in children. However, its effectiveness is uncertain since many children with severe asthma have normal blood eosinophils and the dominance of Th2-mediated inflammation is controversial. Approaches that have revealed gene signatures and biomarkers such as periostin that are specific to adult disease now need to be adopted in children to identify effective pediatric specific therapeutics and minimize the extrapolation of adult therapeutics to children.

  17. Prevention of alcohol misuse among children, youths and young adults

    Directory of Open Access Journals (Sweden)

    Korczak, Dieter

    2011-01-01

    Full Text Available Background: Despite many activities to prevent risky alcohol consumption among adolescents and young adults there is an increase of alcohol intoxications in the group of ten to twenty year old juveniles. Objectives: This report gives an overview about the recent literature as well as the German federal prevention system regarding activities concerning behavioral and policy prevention of risky alcohol consumption among children, adolescents and young adults. Furthermore, effective components of prevention activities are identified and the efficiency and efficacy of ongoing prevention programs is evaluated. Methods: A systematic literature review is done in 34 databases using Bool’sche combinations of the key words alcohol, prevention, treatment, children, adolescents and young adults. Results: 401 studies were found and 59 studies were selected for the health technology assessment (HTA. Most of the studies are done in USA, nine in Germany. A family strengthening program, personalized computer based intervention at schools, colleges and universities, brief motivational interventions and policy elements like increase of prices and taxes proved effective. Discussion: Among the 59 studies there are three meta-analyses, 15 reviews, 17 randomized controlled trials (RCT and 18 cohort studies. Despite the overall high quality of the study design, many of them have methodological weaknesses (missing randomization, missing or too short follow-ups, not clearly defined measurement parameters. The transferability of US-results to the German context is problematic. Only a few prevention activities reach a sustainable reduction of frequency and/or amount of alcohol consumption. Conclusion: The HTA-report shows the need to develop specific and target group focused prevention activities for the German situation. Essential for that is the definition of target goals (reduction of consumption, change of behaviour as well as the definition and empirical validation

    McCreery, Ryan W; Stelmachowicz, Patricia G

    2011-12-01

    This study investigated the relationship between audibility and predictions of speech recognition for children and adults with normal hearing. The Speech Intelligibility Index (SII) is used to quantify the audibility of speech signals and can be applied to transfer functions to predict speech recognition scores. Although the SII is used clinically with children, relatively few studies have evaluated SII predictions of children's speech recognition directly. Children have required more audibility than adults to reach maximum levels of speech understanding in previous studies. Furthermore, children may require greater bandwidth than adults for optimal speech understanding, which could influence frequency-importance functions used to calculate the SII. Speech recognition was measured for 116 children and 19 adults with normal hearing. Stimulus bandwidth and background noise level were varied systematically in order to evaluate speech recognition as predicted by the SII and derive frequency-importance functions for children and adults. Results suggested that children required greater audibility to reach the same level of speech understanding as adults. However, differences in performance between adults and children did not vary across frequency bands.

    1997-02-01

    Future treatment needs for dental services are discussed in the perspective of the objective which the services are meant to fulfill. These are, broadly speaking, equal distribution of services and economic efficiency. Within the Nordic countries, the emphasis has been on equity, perhaps less on efficiency. Equity of utilization is best understood as being a situation where patients with equal needs for oral health care receive equal treatment, in terms of both the volume and the quality of the services. The justification for arguing that equality of utilization is the appropriate measure is mainly based on the externality argument: health-care consumption by one person may be the source of utility to another person. According to that view there are two beneficiaries of dental care: the patient who is sick, and the rest of society who care for the sick patient and who derive utility from seeing the patient become healthy. The public dental services for children in the Nordic countries are organized according to the principle of equity of utilization. Equity of access is best understood as being a situation where people with equal needs have equal opportunity to use dental services. It is a supply-side phenomenon; equal access is achieved when patients with the same needs face the same costs of dental-care consumption in terms of both time and money. The oral health situation among children, adults and the elderly is exemplified by national service data and recent studies.

    2015-12-01

    Obesity potentially arising from viral infection is known as 'infectobesity'. The latest reports suggest that adenovirus-36 (Adv36) is related to obesity in adults and children. Our aim was not only to determine the Adv36 seropositivity in both obese and non-obese children and adults, but also to investigate correlations between antibody positivity and serum lipid profiles. Both Adv36 positivity and tumour-necrosis-factor-alpha, leptin and interleukin-6 levels were detected in blood samples collected from 146 children and 130 adults by ELISA. Fasting plasma triglycerides, total cholesterol and low-density lipoprotein levels were also measured. Adv36 positivity was determined to be 27·1% and 6% in obese and non-obese children and 17·5% and 4% in obese and non-obese adults, respectively. There was no difference with regard to total cholesterol, low-density lipoprotein, triglyceride, tumour-necrosis-factor-alpha and interleukin-6 levels (P > 0·05). However, there was a significant difference between groups in terms of leptin levels (P obese children and adults. Our results showed that Adv36 may be an obesity agent for both adults and children, parallel with current literature data. However, the available data on a possible relationship between Adv36 infection and obesity both in children and adults do not completely solve the problem.

    Full Text Available INTRODUCTION: Ninety five percent of orthodontic patients routinely report pain, due to alterations in the periodontal ligament and surrounding soft tissues, with intensity and prevalence varying according to age. OBJECTIVE: This study aimed to assess toothache and buccal mucosal pain in adults and children during two initial phases of the orthodontic treatment. METHODS: The intensity of toothache and buccal mucosal pain reported by 20 patients, 10 children (11-13 years and 10 adults (18-37 years was recorded with the aid of a Visual Analog Scale (VAS, during 14 days - 7 days with bonded brackets only and 7 days with the initial archwire inserted. RESULTS: There was no significant difference in pain intensity among adults and children. After bracket bonding, 50% of the children and 70% of the adults reported pain. 70% of both groups reported pain after initial archwire insertion. While adults reported constant, low intensity, buccal mucosal pain, the children showed great variation of pain intensity, but with a trend towards decreasing pain during the assessment period. After initial archwire insertion the peaks of toothache intensity and prevalence occurred 24 hours in children and 48 hours in adults. CONCLUSIONS: In general, children reported pain less frequently than adults did, though with greater intensity.

    Full Text Available Childrearing is a process through which parents follow, co-shape and guide their children on their path to personal maturity. Aim of our research is to outline the components of childrearing that 94 participants, members of three generations (28 adults without children, 35 parents and 31 grandparents define as important, both in positive and negative sense. The data was obtained through half-structured interviews with 12 questions on parenting, analysed according to the principles of initial and axial coding of the grounded theory. Results suggest thirty eight components, seventeen positive and eighteen negative, namely. Positive components combined in wider components: cooperation with a child, clear setting of boundaries for a child, acceptance of a child, giving the child possibility for expression, helping the child to get the psychological autonomy and positive parenting. Negative components combined in wider components: uninvolved parenting, psychological pressure on the child, punishing child, lack of trust in a child and negative parenting.

    Full Text Available The present study investigates whether adults and children exhibit different eye‐fixation patterns when they look at human faces, machinelike robotic faces, and humanlike robotic faces. The results from two between‐ subject experiments showed that children and adults did have different facial recognition patterns; children tended to fixate more on the mouth of both machinelike and humanlike robotic faces than they do on human faces, while adults focused more on the eyes. The implications of notable findings and the limitations of the experiment are discussed.

  7. Management of obesity in children differs from that of adults.

    Hoey, Hilary

    2014-11-01

    Obesity in childhood is a very common disorder with an increasing prevalence. It is one of the most serious public health challenges. The objectives of the present paper are to increase the awareness of the problem of obesity in childhood, its serious complications and the need for prevention. Overweight and obese children are likely to remain obese into adulthood and more likely to develop serious complications including health problems such as diabetes and CVD, as well as psychological and social challenges. Overweight and obesity are largely preventable. In adults it is difficult to reduce excessive weight gain once it has become established, thus children should be considered the priority population for intervention strategies and prevention. Nutrition, exercise, weight gain in infancy, genetic and environmental factors, all contribute to the aetiology. Prevention and treatment of obesity in childhood requires education and empowerment of families relating to diet and exercise, along with the regulation and control of food marketing and clear nutritional labelling. The eating and physical activity behaviour of a child is strongly influenced by environmental and social factors. Therefore treatment will have only limited success in an environment where adequate physical activity is inhibited and the consumption of high-energy food is stimulated. Government investment in a health promotion programme addressing the issue of obesity in the population as a whole, with particular emphasis on the prevention and management of obesity in childhood is vital. The family doctor and multidisciplinary team play an important role. Regular visits to the family doctor, including growth assessment, will help motivate the family to restrict energy intake and to increase exercise. Therefore the prevention of childhood obesity needs high priority. PMID:25115345

    2011-11-01

    Full Text Available Humans integrate the features of perceived events and of action plans into episodic event files. Here we investigated whether children (9-10 years, younger adults (20-31 years, and older adults (64-76 years differ in the flexibility of managing (creating and updating event files. Relative to young adults, performance in children and older adults was more hampered by partial mismatches between present and previous stimulus-response relations, suggesting less efficient updating of episodic stimulus-response representations in childhood and old age. Results are discussed in relation to changes in cortical neurochemistry during maturation and senescence.

  9. Does health insurance continuity among low-income adults impact their children's insurance coverage?

    Parent's insurance coverage is associated with children's insurance status, but little is known about whether a parent's coverage continuity affects a child's coverage. This study assesses the association between an adult's insurance continuity and the coverage status of their children. We used data from a subgroup of participants in the Oregon Health Care Survey, a three-wave, 30-month prospective cohort study (n = 559). We examined the relationship between the length of time an adult had health insurance coverage and whether or not all children in the same household were insured at the end of the study. We used a series of univariate and multivariate logistic regression models to identify significant associations and the rho correlation coefficient to assess collinearity. A dose response relationship was observed between continuity of adult coverage and the odds that all children in the household were insured. Among adults with continuous coverage, 91.4% reported that all children were insured at the end of the study period, compared to 83.7% of adults insured for 19-27 months, 74.3% of adults insured for 10-18 months, and 70.8% of adults insured for fewer than 9 months. This stepwise pattern persisted in logistic regression models: adults with the fewest months of coverage, as compared to those continuously insured, reported the highest odds of having uninsured children (adjusted odds ratio 7.26, 95% confidence interval 2.75, 19.17). Parental health insurance continuity is integral to maintaining children's insurance coverage. Policies to promote continuous coverage for adults will indirectly benefit children.

  10. Children Living with HIV-Infected Adults: Estimates for 23 Countries in sub-Saharan Africa.

    Directory of Open Access Journals (Sweden)

    Susan E Short

    Full Text Available In sub-Saharan Africa many children live in extreme poverty and experience a burden of illness and disease that is disproportionately high. The emergence of HIV and AIDS has only exacerbated long-standing challenges to improving children's health in the region, with recent cohorts experiencing pediatric AIDS and high levels of orphan status, situations which are monitored globally and receive much policy and research attention. Children's health, however, can be affected also by living with HIV-infected adults, through associated exposure to infectious diseases and the diversion of household resources away from them. While long recognized, far less research has focused on characterizing this distinct and vulnerable population of HIV-affected children.Using Demographic and Health Survey data from 23 countries collected between 2003 and 2011, we estimate the percentage of children living in a household with at least one HIV-infected adult. We assess overlaps with orphan status and investigate the relationship between children and the adults who are infected in their households.The population of children living in a household with at least one HIV-infected adult is substantial where HIV prevalence is high; in Southern Africa, the percentage exceeded 10% in all countries and reached as high as 36%. This population is largely distinct from the orphan population. Among children living in households with tested, HIV-infected adults, most live with parents, often mothers, who are infected; nonetheless, in most countries over 20% live in households with at least one infected adult who is not a parent.Until new infections contract significantly, improvements in HIV/AIDS treatment suggest that the population of children living with HIV-infected adults will remain substantial. It is vital to on-going efforts to reduce childhood morbidity and mortality to consider whether current care and outreach sufficiently address the distinct vulnerabilities of these

    When children are asked to draw the Earth they often produce intriguing pictures in which, for example, people seem to be standing on a flat disc or inside a hollow sphere. These drawings, and children's answers to questions, have been interpreted as indicating that children construct naïve, theory-like mental models of the Earth (e.g. Vosniadou & Brewer, 1992). However, recent studies using different methods have found little or no evidence of these mental models, and report that many young children have some scientific knowledge of the Earth. To examine the reasons for these contrasting findings, adults (N=350) were given the drawing task previously given to 5-year-old children. Fewer than half of the adults' pictures were scientific, and 15% were identical to children's 'naïve' drawings. Up to half of the answers to questions (e.g. 'Where do people live?') were non-scientific. Open-ended questions and follow-up interviews revealed that non-scientific responses were given because adults found the apparently simple task confusing and challenging. Since children very probably find it even more difficult, these findings indicate that children's non-scientific responses, like adults', often result from methodological problems with the task. These results therefore explain the discrepant findings of previous research, and support the studies which indicate that children do not have naïve mental models of the Earth.

    Psychiatric and behavior problems are common among children and young adults, and many go without care or only receive treatment in carceral settings. We examined racial and ethnic disparities in children's and young adults' receipt of mental health and substance abuse care using nationally representative data from the 2006-2012 Medical Expenditure Panel Surveys. Blacks' and Hispanics' visit rates (and per capita expenditures) were about half those of non-Hispanic whites for all types and definitions of outpatient mental health services. Disparities were generally larger for young adults than for children. Black and white children had similar psychiatric inpatient and emergency department utilization rates, while Hispanic children had lower hospitalization rates. Multivariate control for mental health impairment, demographics, and insurance status did not attenuate racial/ethnic disparities in outpatient care. We conclude that psychiatric and behavioral problems among minority youth often result in school punishment or incarceration, but rarely mental health care. PMID:27520100

  14. Surviving Parents' Influence on Adult Children's Depressive Symptoms Following the Death of a First Parent.

    Parents and children are linked across the life course, and they share common experiences. This article focuses on the bereavement experience of adult children's loss of a first parent during adulthood and examines the downward influence of emotional closeness with a surviving parent on adult children's depressive symptoms following loss. Analyses are based on adult children who experienced the death of a first parent (N = 227), drawn from the Longitudinal Study of Generations, a study of three-and four-generation families from Southern California. Multilevel lagged dependent variable models indicate that an emotionally close relationship with a surviving parent is related with fewer post-bereavement depressive symptoms when a mother survives a father, but not vice versa. This analysis extends the theory of linked lives and highlights the mutual influence parents and children exert, as well as the complex role of gender in shaping family relationships.

    Observing social interactions between children and adults is a major method in the toolkit of psychologists who examine social development and social relationships. Although this method has revealed many interesting phenomena, it cannot determine the effect of behavior independent of other traits. Research on the role of attractiveness in social development provides an example of this conundrum: Are attractive and unattractive children/adults treated differently because of their attractivenes...

    We investigated the impact of early childhood and adulthood bilingualism on the attention system in a group of linguistically and culturally homogeneous children (5- and 6-year olds) and young adults. We administered the child Attention Network Test (ANT) to 63 English monolingual and Korean-English bilingual children and administered the adult ANT to 39 language- and culture-matched college students. Advantageous bilingual effects on attention were observed for both children and adults in global processing levels of inverse efficiency, response time, and accuracy at a magnitude more pronounced for children than for adults. Differential bilingualism effects were evident at the local network level of executive control and orienting in favor of the adult bilinguals only. Notably, however, bilingual children achieved an adult level of accuracy in the incongruent flanker condition, implying enhanced attentional skills to cope with interferences. Our findings suggest that although both child and adult bilinguals share cognitive advantages in attentional functioning, age-related cognitive and linguistic maturation differentially shapes the outcomes of attentional processing at a local network level.

    2013-01-01

    While there has been a fair amount of research investigating children's syntactic processing during spoken language comprehension, and a wealth of research examining adults' syntactic processing during reading, as yet very little research has focused on syntactic processing during text reading in children. In two experiments, children and adults read sentences containing a temporary syntactic ambiguity while their eye movements were monitored. In Experiment 1, participants read sentences such as, 'The boy poked the elephant with the long stick/trunk from outside the cage' in which the attachment of a prepositional phrase was manipulated. In Experiment 2, participants read sentences such as, 'I think I'll wear the new skirt I bought tomorrow/yesterday. It's really nice' in which the attachment of an adverbial phrase was manipulated. Results showed that adults and children exhibited similar processing preferences, but that children were delayed relative to adults in their detection of initial syntactic misanalysis. It is concluded that children and adults have the same sentence-parsing mechanism in place, but that it operates with a slightly different time course. In addition, the data support the hypothesis that the visual processing system develops at a different rate than the linguistic processing system in children.

    2016-01-01

    Objective To retrospectively evaluate the effectiveness of extracorporeal shock wave lithotripsy (ESWL) for urolithiasis and compare the results between children and adults. Materials and methods From January 2011 to January 2015 (four years), ESWL was performed in 104 children and 300 adults for urolithiasis. MODULITH® SLX-F2 lithotripter (Storz Medical AG, Tägerwilen, Switzerland) equipment was used for ESWL. The stone-free rates, the number of ESWL sessions required, complication rates and ancillary procedures used were evaluated in a comparative manner. Results The mean age ± standard deviation (SD) of children was 7.84±4.22 years and of adults was a 40.22±1.57 years. Mean ± SD of the stone size was 1.28±61 cm in the adults while 1.08 ± 0.59 cm in the children. In adults, the complications included steinstrasse in six (1.98%) patients, fever in 15 (4.95%), hematuria in 19 (6.28%) and sepsis in six (1.98%) patients. In children, steinstrasse was observed in two (1.9%), mild fever in two (1.9%), hematuria in six (5.7%) and sepsis was seen in four (3.8%) patients. The overall complication rate in the adults and in the children, it was found to be 46/300 (15%) and in the children, it was seen to be 14/104 (13%). No statistical difference was found in post-ESWL complications between children and adults (P>0.05). Ancillary procedures including double J (DJ) stent were used in 13 (12.5%) children and 87 (29%) adults. There was a better stone clearance rate in children i.e. 79% as compared to 68% in adults (X2: P=0.036). Conclusion Children can achieve high stone-free rates after ESWL with a lower need for repeat ancillary procedures as compared to adults. However, there is a difference in the post-ESWL complications between these groups. PMID:27800291

    2015-03-01

    Full Text Available Background: Data on the physical strength capabilities are essential for design-ing safe and usable products and are useful in a wide range of clinical settings especially during treatment of disease affecting the function of the hand. The purpose of this study was to determine peak lateral pinch strength, key pinch strength, tip-to-tip pinch strength and three-jaw pinch strength exertions in a healthy Iranian children and young adult population.Methods: The study was conducted among 511 participants (242 males and 269 females aged 7-30 years. Measurements were carried out with both dominant and non-dominant hands in standard sitting posture using a B&L pinch gauge. Two repetitions of each strength measurement were recorded for each condition and the average value of the two trials was used in the subsequent analysis.Results: The results showed significant differences in the pinch strength data in terms of the age, gender and hand dominance. The lateral pinch strength, key pinch strength, tip-to-tip pinch strength and three-jaw pinch strength exertions by females were 68.4%, 68.8%, 78.8% and 81.8% of those exerted by males, respectively. Strength exertions with the non-dominant hand were 6.4%, 5.2%, 6.6% and 5.1% lower than strength exertions of the dominant hand for the lat-eral pinch strength, key pinch strength, tip-to-tip pinch strength and three-jaw pinch strength exertions, respectively.Conclusion: These findings can be used to fill the gaps in strength data for Iranian population.

    Directory of Open Access Journals (Sweden)

    Amy M Bernhardt

    Full Text Available OBJECTIVES: Quick service restaurant (QSR television advertisements for children's meals were compared with adult advertisements from the same companies to assess whether self-regulatory pledges for food advertisements to children had been implemented. METHODS: All nationally televised advertisements for the top 25 US QSR restaurants from July 1, 2009 to June 30, 2010 were obtained and viewed to identify those advertising meals for children and these advertisements were compared with adult advertisements from the same companies. Content coding included visual and audio assessment of branding, toy premiums, movie tie-ins, and depictions of food. For image size comparisons, the diagonal length of the advertisement was compared with the diagonal length of salient food and drink images. RESULTS: Almost all of the 92 QSR children's meal advertisements that aired during the study period were attributable to McDonald's (70% or Burger King (29%; 79% of 25,000 television placements aired on just four channels (Cartoon Network, Nickelodeon, Disney XD, and Nicktoons. Visual branding was more common in children's advertisements vs. adult advertisements, with food packaging present in 88% vs. 23%, and street view of the QSR restaurant present in 41% vs. 12%. Toy premiums or giveaways were present in 69% vs. 1%, and movie tie-ins present in 55% vs. 14% of children's vs. adult advertisements. Median food image diagonal length was 20% of the advertisement diagonal for children's and 45% for adult advertisements. The audio script for children's advertisements emphasized giveaways and movie tie-ins whereas adult advertisements emphasized food taste, price and portion size. CONCLUSIONS: Children's QSR advertisements emphasized toy giveaways and movie tie-ins rather than food products. Self-regulatory pledges to focus on actual food products instead of toy premiums were not supported by this analysis.

    Full Text Available This study examined neurocognitive differences between children and adults in the ability to learn and adapt simple stimulus–response associations through feedback. Fourteen typically developing children (mean age = 10.2 and 15 healthy adults (mean age = 25.5 completed a simple task in which they learned to associate visually presented stimuli with manual responses based on performance feedback (acquisition phase, and then reversed and re-learned those associations following an unexpected change in reinforcement contingencies (reversal phase. Electrophysiological activity was recorded throughout task performance. We found no group differences in learning-related changes in performance (reaction time, accuracy or in the amplitude of event-related potentials (ERPs associated with stimulus processing (P3 ERP or feedback processing (feedback-related negativity; FRN during the acquisition phase. However, children's performance was significantly more disrupted by the reversal than adults and FRN amplitudes were significantly modulated by the reversal phase in children but not adults. These findings indicate that children have specific difficulties with reinforcement learning when acquired behaviours must be altered. This may be caused by the added demands on immature executive functioning, specifically response monitoring, created by the requirement to reverse the associations, or a developmental difference in the way in which children and adults approach reinforcement learning.

  8. Temporal lobe epilepsy surgery in children versus adults: from etiologies to outcomes

    Full Text Available Temporal lobe epilepsy (TLE is the most common type of medically intractable epilepsy in adults and children, and mesial temporal sclerosis is the most common underlying cause of TLE. Unlike in the case of adults, TLE in infants and young children often has etiologies other than mesial temporal sclerosis, such as tumors, cortical dysplasia, trauma, and vascular malformations. Differences in seizure semiology have also been reported. Motor manifestations are prominent in infants and young children, but they become less obvious with increasing age. Further, automatisms tend to become increasingly complex with age. However, in childhood and especially in adolescence, the clinical manifestations are similar to those of the adult population. Selective amygdalohippocampectomy can lead to excellent postoperative seizure outcome in adults, but favorable results have been seen in children as well. Anterior temporal lobectomy may prove to be a more successful surgery than amygdalohippocampectomy in children with intractable TLE. The presence of a focal brain lesion on magnetic resonance imaging is one of the most reliable independent predictors of a good postoperative seizure outcome. Seizure-free status is the most important predictor of improved psychosocial outcome with advanced quality of life and a lower proportion of disability among adults and children. Since the brain is more plastic during infancy and early childhood, recovery is promoted. In contrast, long epilepsy duration is an important risk factor for surgically refractory seizures. Therefore, patients with medically intractable TLE should undergo surgery as early as possible.

  9. Regulation of naturally acquired mucosal immunity to Streptococcus pneumoniae in healthy Malawian adults and children.

    Directory of Open Access Journals (Sweden)

    Sarah J Glennie

    Full Text Available Worldwide, invasive pneumococcal disease caused by Streptococcus pneumoniae is most common in young children. In adults, disease rates decline following intermittent colonization and the acquisition of naturally acquired immunity. We characterized mucosal and systemic pneumococcal-specific T-cell responses in African children and adults who contend with intense rates of colonization, up to 100% and 60% respectively. We find most Malawian children have high pneumococcal-specific T-cell responses in tonsil tissue and peripheral blood. In addition, frequent commensalism generates CD25(hi (Tregs which modulate mucosal pneumococcal-specific T-cell responses in some children and ≥50% of adults. We propose that immune regulation may prolong pneumococcal colonization and predispose vulnerable individuals to disease.

  10. Updates on the Diagnosis of Helicobacter pylori Infection in Children: What Are the Differences between Adults and Children?

    Helicobacter pylori infection is acquired mainly during childhood and causes various diseases such as gastritis, peptic ulcer disease, mucosa-associated lymphoid tissue (MALT) lymphoma, and iron deficiency anemia. Although H. pylori infection in children differs from adults in many ways, this is often overlooked in clinical practice. Unlike adults, nodular gastritis may be a pathognomonic endoscopic finding of childhood H. pylori infection. Histopathological findings of gastric tissues are also different in children due to predominance of lymphocytes and plasma cells and the formation of gastric MALT. Although endoscopy is recommended for the initial diagnosis of H. pylori infection, several non-invasive diagnostic tests such as the urea breath test (UBT) and the H. pylori stool antigen test (HpSA) are available and well validated even in children. According to recent data, both the (13)C-UBT and HpSA using enzyme-linked immunosorbent assay are reliable non-invasive tests to determine H. pylori status after eradication therapy, although children younger than 6 years are known to have high false positives. When invasive or noninvasive tests are applied to children to detect H. pylori infection, it should be noted that there are differences between children and adults in diagnosing H. pylori infection.

    Working memory (WM) - temporary storage and manipulation of information in the mind - is a key component of cognitive maturation, and structural brain changes throughout development are associated with refinements in WM. Recent functional neuroimaging studies have shown that there is greater activation in prefrontal and parietal brain regions with increasing age, with adults showing more refined, localized patterns of activations. However, few studies have investigated the neural basis of verbal WM development, as the majority of reports examine visuo-spatial WM. We used fMRI and a 1-back verbal WM task with six levels of difficulty to examine the neurodevelopmental changes in WM function in 40 participants, twenty-four children (ages 9-15 yr) and sixteen young adults (ages 20-25 yr). Children and adults both demonstrated an opposing system of cognitive processes with increasing cognitive demand, where areas related to WM (frontal and parietal regions) increased in activity, and areas associated with the default mode network decreased in activity. Although there were many similarities in the neural activation patterns associated with increasing verbal WM capacity in children and adults, significant changes in the fMRI responses were seen with age. Adults showed greater load-dependent changes than children in WM in the bilateral superior parietal gyri, inferior frontal and left middle frontal gyri and right cerebellum. Compared to children, adults also showed greater decreasing activation across WM load in the bilateral anterior cingulate, anterior medial prefrontal gyrus, right superior lateral temporal gyrus and left posterior cingulate. These results demonstrate that while children and adults activate similar neural networks in response to verbal WM tasks, the extent to which they rely on these areas in response to increasing cognitive load evolves between childhood and adulthood.

  17. Make your own kinds of cues: when children make more accurate inferences than adults.

    Ruggeri, Azzurra; Katsikopoulos, Konstantinos V

    2013-07-01

    In everyday decision making, we do not always have the luxury of using certain knowledge but often need to rely on cues, that is, pieces of information that can aid reasoning. We ask whether and under what circumstances children can focus on informative cues and make accurate inferences in real-world problems. We tested second-, third-, and fifth-grade children and young adults on two problems: which of two real cars is more expensive and which of two real cities has more inhabitants. We manipulated whether cues were given to the participants or the participants needed to generate their own cues. The main result was that when generating their own cues, younger children matched older children and young adults in accuracy or even outperformed them. On the other hand, when cues were given, children were less accurate than young adults. A possible explanation for this result is that children, on their own, tend to generate "perceptual" cues (e.g., "Which car is longer?") that are informative in the problems we studied. However, children are not able to recognize the most informative cues in a set that is given to them because they are not familiar with all cues (e.g., non-perceptual cues such as which car has more horsepower).

  18. "Difficult" children as elicitors and targets of adult communication patterns: an attributional-behavioral transactional analysis.

    Science.gov (United States)

    Bugental, D B; Shennum, W A

    1984-01-01

    A transactional model of adult-child interaction was proposed and tested. In determining the effects that caregivers and children have on each other, it was maintained that adult attributions act as important moderators in the interaction process. Specifically, it was predicted that adult beliefs about the causes of caregiving outcomes act as selective filters or sensitizers to child behavior--determining the nature and amount of adult reaction to different child behaviors. It was further predicted that adult attributions act in a self-fulfilling fashion, that is, the communication patterns that follow from caregiver beliefs act to elicit child behavior patterns that maintain those beliefs. In a synthetic family strategy, elementary-school-aged boys were paired with unrelated mothers (N = 96) for videotaped interactions. Children were either trained or preselected on two orthogonal dimensions: responsiveness and assertiveness. Mothers were premeasured on their self-perceived power as caregivers (S+) and the social power they attributed to children (C+). Videotapes were analyzed separately for adult facial expression and posture, voice intonation, and verbal communication. Each of these behavioral dimensions was measured on the dimensions of affect, assertion, and "maternal quality" (e.g., baby-talk). We expected low self-perceived power to sensitize the adult to variations in child responsiveness and high child-attributed power to sensitize the adult to variations in child assertiveness. Two transactional sequences were obtained (the same patterns were obtained for acted and dispositional enactments of child behavior): 1. Low S+ mothers (in comparison with high S+ mothers) were selectively reactive to child unresponsiveness. These adults reacted to unresponsive children with a communication pattern characterized by a "maternal" quality, negative affect, and positive affect that was unassertively inflected. Unresponsive children, in turn, reacted to low S+ mothers

    A severe burn leads to hypermetabolism and catabolism resulting in compromised function and structural changes of essential organs. The release of cytokines has been implicated in this hypermetabolic response. The severity of the hypermetabolic response following burn injury increases with age, as does the mortality rate. Due to the relationship between the hypermetabolic and inflammatory responses, we sought to compare the plasma cytokine profiles following a severe burn in adults and in children. We enrolled 25 adults and 24 children who survived a flame burn covering more than 20% of total body surface area (TBSA). The concentrations of 22 cytokines were measured using the Linco multiplex array system (St. Charles, MO, USA). Large perturbations in the expression of pro- and anti-inflammatory cytokines were seen following thermal injury. During the first week following burn injury, IFN-γ, IL-10, IL-17, IL-4, IL-6, and IL-8 were detected at significantly higher levels in adults compared with children, P < 0.05. Significant differences were measured during the second week post-burn for IL-1β (higher in children) and IL-5 (higher in adults), P < 0.05. IL-18 was more abundant in children compared with adults during the third week post-burn, P < 0.05. Between post-burn d 21 and d 66, IL-1α was detected at higher concentrations in pediatric compared with adult patients, P < 0.05. Only GM-CSF expression was significantly different at all time points; it was detected at lower levels in pediatric patients, P < 0.05. Eotaxin, G-CSF, IL-13, IL-15, IP-10, MCP-1, and MIP-1α were detected at significantly different concentrations in adult compared with pediatric patients at multiple time points, P < 0.05. There were no differences in IL-12, IL-2, IL-7, or TNF levels in adult compared with pediatric burn patients at any of these time points. Following severe flame burns, the cytokine profiles in pediatric patients differ compared with those in adult patients, which may

    2002-09-01

    This study investigated developmental trends associated with the Deese/Roediger-McDermott false-memory effect, the role of distinctive information in false-memory formation, and participants' subjective experience of true and false memories. Children (5- and 7-year-olds) and adults studied lists of semantically associated words. Half of the participants studied words alone, and half studied words accompanied by pictures. There were significant age differences in recall (5-year-olds evinced more false memories than did adults) but not in recognition of critical lures. Distinctive information reduced false memory for all age groups. Younger children provided with distinctive information, and older children and adults regardless of whether they viewed distinctive information, expressed higher levels of confidence in true than in false memories. Source attributions did not significantly differ between true and false memories. Implications for theories of false memory and memory development are discussed. PMID:12220049

    Full Text Available This study used graph analysis to investigate how age differences modify the structure of semantic word association networks of children and adults and if the networks present a small-world structure and a scale-free distribution which are typical of natural languages. Three age groups of Brazilian Portuguese speakers (children, adults and elderly people participated in the experiment. Quantitative and qualitative measures suggested that adults and elderly speakers have similar network structures. Children's network showed fewer nodes, connections and clusters, and longer inter-node distances. All networks presented a small-world structure, but they did not show entirely scale-free distributions. These results suggest that from childhood to adulthood, there is an increase not only in the number of words semantically linked to a target but also an increase in the connectivity of the network.

    A study on the seroprevalence of toxocariasis, using ELISA with Toxocara larval excretory-secretory antigens, was carried out on human populations in two regions of Spain. Sera from a population of 195 children from Madrid and 143 children from Santa Cruz de Tenerife (Canary Isles), showed a prevalence of 0% and 4.2% respectively. Sera from a population of 272 adults from Madrid and 803 adults from Santa Cruz de Tenerife showed a prevalence of 3.6% and 17.4%. Reasons for these differences in the seroprevalence of Toxocara in the different age groups from the two regions are discussed.

  5. Algodystrophy in children and young adults with isotopic bony hypofixation. A propos of 5 observations

    International Nuclear Information System (INIS)

    The authors report 5 observations of young adults 3 teen-agers and 2 children suffering from algodystrophy, and in whom isotopic exploration of the skeleton disclosed a clear bony hypofixation during the entire evolution. These observations confirm their 1981 work concerning a young adult suffering from algodystrophy with isotopic bony hypofixation. Recent Canadian and American studies emphasize also the frequency of isotopic hypofixation in children algodystrophy. It seems, therefore, that isotopic bony hypofixation (linked perhaps to a decreased blood flow), is rather specific of algodystrophy in young subjects

    Full Text Available The aim of this research was to find out the language produced by the school-aged children and the adult in a TV show. The study was carried out applying descriptive qualitative research design. The data for this research included the conversations between an adult (the host and three school-aged children. The data analysis procedures included- observing the video, transcribing the conversation, identifying the linguistics and non-linguistics features of the utterances, categorizing the language produced by the children and the adult, and interpreting the result of the analysis. The findings of data analysis showed that the five-year-old children produced one-word and two-word utterances rather than longer sentences. In contrast, the seven-year-old child produced longer sentences rather than one-word or two-word utterances. On the other hand, the host applied different ways and modified the way she produced language (‘caregiver speech’ or ‘motherese’ such as using exclamation, using gestures, using complimenting words, using intimate pronouns, and using direct instruction. The results obtained indicated that the school-aged children and the adult have their own ways in producing language in a TV show in Indonesia.

  10. In Need of Creative Mobile Service Ideas? Forget Adults and Ask Young Children

    Full Text Available It is well acknowledged that innovation is a key success factor in the mobile service domain. Having creative ideas is the first critical step in the innovation process. Many studies suggest that customers are a valuable source of creative ideas. However, the literature also shows that adults may be constrained by existing technology frames, which are known to hinder creativity. Instead young children (aged 7-12 are considered digital natives yet are free from existing technology frames. This led us to study them as a potential source for creative mobile service ideas. A set of 41,000 mobile ideas obtained from a research project in 2006 granted us a unique opportunity to study the mobile service ideas from young children. We randomly selected two samples of ideas (N = 400 each; one contained the ideas from young children, the other from adults (aged 17-50. These ideas were evaluated by several evaluators using an existing creativity framework. The results show that the mobile service ideas from the young children are significantly more original, transformational, implementable, and relevant than those from the adults. Therefore, this study shows that young children are better sources of novel and quality ideas than adults in the mobile services domain. This study bears significant contributions to the creativity and innovation research. It also indicates a new and valuable source for the companies that seek creative ideas for innovative products and services.

    This study compared rCBF pattern in normal adult and normal children using statistical parametric mapping (SPM). The purpose of this study was to determine distribution pattern not seen visual analysis in both groups. Tc-99m ECD brain SPECT was performed in 12 normal adults (M:F=11:1, average age 35 year old) and 6 normal control children (M:F=4:2, 10.5{+-}3.1y) who visited psychiatry clinic to evaluate ADHD. Their brain SPECT revealed normal rCBF pattern in visual analysis and they were diagnosed clinically normal. Using SPM method, we compared normal adult group's SPECT images with those of 6 normal children subjects and measured the extent of the area with significant hypoperfusion and hyperperfusion (p<0.001, extent threshold=16). The areas of both angnlar gyrus, both postcentral gyrus, both superior frontal gyrus, and both superior parietal lobe showed significant hyperperfusion in normal adult group compared with normal children group. The areas of left amygdala gyrus, brain stem, both cerebellum, left globus pallidus, both hippocampal formations, both parahippocampal gyrus, both thalamus, both uncus, both lateral and medial occipitotemporal gyrus revealed significantly hyperperfusion in the children. These results demonstrated that SPM can say more precise anatomical area difference not seen visual analysis.

    Full Text Available The aim of this research paper is to find out by comparing and contrasting between the adults and children in second language learning process how language ego of adult learners affects them to learn second language, and how it becomes a barrier for them in second language learning process. Nowadays learning English as foreign and second language is one of the most dominant socio-cultural   requirements of people for seeking employment, foreign tour, business, education and other basic communicative purposes. Therefore, English as foreign and second language is definitely necessary for everybody because it is one of the most urgent socio-cultural pre-requisites of the Post-modern era. It is commonly observed during teaching and learning English as a foreign language in Pakistan, that language ego hinders the adults to learn it properly. Therefore, children are more successful L2 learners than the adults are. Children learning L2 use to reproduce construction process just as they do in their L1 learning and they have the ability to cognize and reproduce new and novel utterances. The compare and contrast between adult and child second language learner will be highlighted in this research paper, which may be helpful for teachers, researchers and scholars on the subject.  Keywords:  Second Language Learning Process, Adult Learner, Child Learner, Language Ego, Critical Period and Puberty Period

    1992-05-01

    In Phase 1 of this study, we asked 23 parents between the ages of 30 and 52 years and 26 children between the ages of 10 and 19 years to list effects of television and video games on children. A questionnaire was developed using the most frequently given responses (e.g., television influences children's aggressive behavior, verbal abilities, or time with friends). In Phase 2, this questionnaire was administered to different groups of parents and children and a control group of adults without offspring (N = 204) who were asked to rate the influence of each item on the questionnaire. Multivariate analyses of variance indicated that there were similarities and differences among the groups. For example, parents and other adults held similar beliefs about the influence of television, but parents held more positive beliefs about the influence of video games than the other adults. Children held more positive beliefs about the influence of television than parents, but parents and children held similar beliefs about the influence of video games. PMID:1527774

  3. Mothers' Adult Attachment Interview ratings predict preschool children's IQ following domestic violence exposure.

    Science.gov (United States)

    Busch, Amy L; Lieberman, Alicia F

    2010-11-01

    This study examined links between mothers' Adult Attachment Interview ratings (AAI; Main, Goldwyn, & Hesse, 2003) and their preschool children's IQ among 70 families who had experienced domestic violence. As predicted, children displayed significantly stronger verbal and perceptual-organizational abilities when their mothers exhibited more secure, i.e. coherent, states of mind regarding attachment. Mothers' coherence of mind on the AAI explained 18% of the variance in children's Verbal IQ and 12% of the variance in children's Performance IQ, after controlling for maternal education. Mothers' attachment security also was related to children's total IQ score, but this association was accounted for by effects on children's Verbal IQ. Children whose mothers were rated as unclassifiable on the AAI and those whose mothers were unresolved/insecure had lower IQ scores. Although mothers who appeared more secure on the AAI were more sensitively responsive toward their children, mediational analyses suggested that there was a direct link between mothers' security and children's IQ that was not explained by sensitive parenting. This suggests that clinical interventions for children exposed to domestic violence should include helping their mothers achieve coherent ways of thinking about their own childhood experiences, including past trauma.

    Celiac disease (CD) is developed after gluten ingestion in genetically susceptible individuals. It can appear at any time in life, but some differences are commonly observed between individuals with onset early in life or in adulthood. We aimed to investigate the molecular basis underlying those differences. We collected 19 duodenal biopsies of children and adults with CD and compared the expression of 38 selected genes between each other and with the observed in 13 non-CD controls matched by age. A Bayesian methodology was used to analyze the differences of gene expression between groups. We found seven genes with a similarly altered expression in children and adults with CD when compared to controls (C2orf74, CCR6, FASLG, JAK2, IL23A, TAGAP and UBE2L3). Differences were observed in 13 genes: six genes being altered only in adults (IL1RL1, CD28, STAT3, TMEM187, VAMP3 and ZFP36L1) and two only in children (TNFSF18 and ICOSLG); and four genes showing a significantly higher alteration in adults (CCR4, IL6, IL18RAP and PLEK) and one in children (C1orf106). This is the first extensive study comparing gene expression in children and adults with CD. Differences in the expression level of several genes were found between groups, being notorious the higher alteration observed in adults. Further research is needed to evaluate the possible genetic influence underlying these changes and the specific functional consequences of the reported differences. PMID:26859134

    Although an association between exposure to phthalates in house dust and childhood asthma or allergies has been reported in recent years, there have been no reports of these associations focusing on both adults and children. We aimed to investigate the relationships between phthalate levels in Japanese dwellings and the prevalence of asthma and allergies in both children and adult inhabitants in a cross-sectional study. The levels of seven phthalates in floor dust and multi-surface dust in 156 single-family homes were measured. According to a self-reported questionnaire, the prevalence of bronchial asthma, allergic rhinitis, allergic conjunctivitis, and atopic dermatitis in the 2 years preceding the study was 4.7%, 18.6%, 7.6%, and 10.3%, respectively. After evaluating the interaction effects of age and exposure categories with generalized liner mixed models, interaction effects were obtained for DiNP and bronchial asthma in adults (Pinteraction=0.028) and for DMP and allergic rhinitis in children (Pinteraction=0.015). Although not statistically significant, children had higher ORs of allergic rhinitis for DiNP, allergic conjunctivitis for DEHP, and atopic dermatitis for DiBP and BBzP than adults, and liner associations were observed (Ptrendphthalates levels collected from multi-surfaces. This study suggests that the levels of DMP, DEHP, DiBP, and BBzP in floor dust were associated with the prevalence of allergic rhinitis, conjunctivitis, and atopic dermatitis in children, and children are more vulnerable to phthalate exposure via household floor dust than are adults. The results from this study were shown by cross-sectional nature of the analyses and elaborate assessments for metabolism of phthalates were not considered. Further studies are needed to advance our understanding of phthalate toxicity.

  6. The effect of attentional load on implicit sequence learning in children and young adults

    2014-05-01

    Full Text Available We investigated the effect of a secondary task on implicit sequence learning in children and young adults. A serial reaction time task was administered to 8-to-10 year old children and 18-to-22 year old adults. Participants reacted to the location of a target presented in one of four locations on the screen with a spatially corresponding response key. Unknown to participants, the location at which the target appeared was structured according to a deterministic sequence. Occasionally, the black target dot was replaced by a red target dog. To assess the effect of attentional load on implicit sequence learning, half of the participants of each age group was assigned to the single task condition, while the other half executed the task under dual task conditions. Whereas participants in the single task condition could ignore the change in target identity, dual task participants additionally had to count the number of times the black dot was replaced by a red dog to increase the attentional load. Sequence learning was tested under single task conditions in both conditions. Z-transformed results indicate that young adults generally showed more sequence learning than children. Importantly, the secondary task had no effect on sequence learning in children, since children learned as much under dual task conditions as under single task conditions. Adults, on the other hand, showed a different result pattern, as they displayed more sequence learning under single task than under dual task conditions. We surmise that this result is due to the vainly attempt of adults, but not children, to integrate both sequences.

    Directory of Open Access Journals (Sweden)

    Jost B Jonas

    Full Text Available Since high myopia in the younger generation may differ etiologically from high myopia in older generations, we examined whether education-related parameters differ between high myopia in today´s school children and high pathological myopia in today´s elderly generation.The investigation included the adult populations of the population-based Beijing Eye Study (BES (3468 adults;mean age:64.6±9.8years;range:50-93years and Central India Eye and Medical Study (CIEMS (4711 adults;age:49.±13.2years;range:30-100years, and the children and teenager populations of the Shandong Children Eye Study (SCES (6026 children;age:9.7±3.3years;range:4-18years;cycloplegic refractometry, Gobi Desert Children Eye Study (1565;age:11.9±3.5years;range:6-21 years;cycloplegic refractometry, Beijing Pediatric Eye Study (681 children;age:7.7±1.6years;range:5-13 years;non-cycloplegic refractometry,calculation of axial length to corneal curvature radius ratio, Beijing Children Eye Study (15066 children;age:13.2±3.4years;range:7-18years;non-cycloplegic refractometry, Beijing High School Teenager Eye Study (4677 children;age:16.9±0.7years;range:16-18years;non-cycloplegic refractometry.In the BES and CIEMS, educational level did not differ significantly between, or was significantly lower in the highly myopic group (myopic refractive error ≥6 diopters than in the non-highly myopic group. In all non-adult study populations, higher prevalence of high myopia was significantly associated with higher degree of education related parameters such as attendance of high-level schools, and more time spent for indoors near work versus time spent outdoors.Comparing associations of old or genetic high myopia in adults with new or acquired high myopia in school children revealed that education-related parameters did not show a clear association with old or genetic high myopia, while in contrast, new high myopia showed strong associations with education. It confirms previous studies

    Lerman, Dorothea C; Hawkins, Lynn; Hillman, Conrad; Shireman, Molly; Nissen, Melissa A

    2015-01-01

    Adults with autism spectrum disorder (ASD), who were interested in working as behavior technicians for young children with autism, participated in 2 experiments. Participants included 5 adults with Asperger syndrome or pervasive developmental disorder not otherwise specified, 19 to 23 years old, and 11 children with autism, 3 to 7 years old. In Experiment 1, training of the adults focused on the implementation of mand training via incidental teaching. Experiment 2 focused on teaching participants to use discrete-trial training (DTT) with children who exhibited problem behavior. Both experiments showed that behavioral skills training was effective for teaching the adult participants the behavioral procedures needed to teach children with autism. In addition, the children acquired skills as a result of training. Results of Experiment 2 further demonstrated that the DTT skills generalized across untrained targets and children. Social validity ratings suggested that some participants' teaching was indistinguishable from that of individuals without ASD.

  12. Producing morphologically complex words: An ERP study with children and adults

    Directory of Open Access Journals (Sweden)

    Mary-Jane Budd

    2015-04-01

    Full Text Available A widely studied morphological phenomenon in psycholinguistic research is the plurals-inside-compounds effect in English, which is the avoidance of regular plural modifiers within compounds (e.g., *rats hunter. The current study employs event-related brain potentials (ERPs to investigate the production of plurals-inside-compounds in children and adults. We specifically examined the ERP correlates of producing morphologically complex words in 8-year-olds, 12-year-olds and adults, by recording ERPs during the silent production of compounds with plural or singular modifiers. Results for both children and adults revealed a negativity in response to compounds produced from regular plural forms when compared to compounds formed from irregular plurals, indicating a highly specific brain response to a subtle linguistic contrast. Although children performed behaviourally with an adult-like pattern in the task, we found a broader distribution and a considerably later latency in children's brain potentials than in adults’, indicating that even in late childhood the brain networks involved in language processing are subject to subtle developmental changes.

  9. Children and adults use attractiveness as a social cue in real people and avatars.

    Principe, Connor P; Langlois, Judith H

    2013-07-01

    Observing social interactions between children and adults is a major method in the toolkit of psychologists who examine social development and social relationships. Although this method has revealed many interesting phenomena, it cannot determine the effect of behavior independent of other traits. Research on the role of attractiveness in social development provides an example of this conundrum: Are attractive and unattractive children/adults treated differently because of their attractiveness (independent of their behavior), do they behave differently and thus elicit differential treatment, or both? Virtual world and avatar-based technologies allow researchers to control the social behaviors of targets; however, whether children and adults use the facial attractiveness of avatars as a social cue in the same way as they do with real peers is currently unknown. Using Mii avatars from the popular Nintendo Wii video game console, Study 1 found that the facial attractiveness ratings of real people strongly predicted the attractiveness ratings of avatar faces based on the former group. Study 2 revealed that adults (n=46) and children (n=42) prefer attractive avatars as social partners. The results of this set of methodological studies may help to clarify future research on the relationship between attractiveness and behavior throughout the lifespan. Furthermore, the use of avatars may allow studies to experimentally examine the effects of attractiveness in situations where such research is not ethical (e.g., peer victimization). PMID:23399311

    Full Text Available We investigate the number preferences of children and adults when generating random digit sequences. Previous research has shown convincingly that adults prefer smaller numbers when randomly choosing between responses 1-6. We analyse randomisation choices made by both children and adults, considering a range of experimental studies and task configurations. Children – most of whom are between 8 and 11 years- show a preference for relatively large numbers when choosing numbers 1-10. Adults show a preference for small numbers with the same response set. We report a modest association between children’s age and numerical bias. However, children also exhibit a small number bias with a smaller response set available, and they show a preference specifically for the numbers 1-3 across many datasets. We argue that number space demonstrates both continuities (numbers 1-3 have a distinct status and change (a developmentally emerging bias towards the left side of representational space or lower numbers.

    In everyday life, we are often faced with the problem of judging who owns an object. The current experiments show that children and adults base ownership judgments on group stereotypes, which relate kinds of people to kinds of objects. Moreover, the experiments show that reliance on stereotypes can override another means by which people make…

  10. Analysis of RF exposure in the head tissues of children and adults

    International Nuclear Information System (INIS)

    This paper analyzes the radio frequencies (RF) exposure in the head tissues of children using a cellular handset or RF sources (a dipole and a generic handset) at 900, 1800, 2100 and 2400 MHz. Based on magnetic resonance imaging, child head models have been developed. The maximum specific absorption rate (SAR) over 10 g in the head has been analyzed in seven child and six adult heterogeneous head models. The influence of the variability in the same age class is carried out using models based on a morphing technique. The SAR over 1 g in specific tissues has also been assessed in the different types of child and adult head models. Comparisons are performed but nevertheless need to be confirmed since they have been derived from data sets of limited size. The simulations that have been performed show that the differences between the maximum SAR over 10 g estimated in the head models of the adults and the ones of the children are small compared to the standard deviations. But they indicate that the maximum SAR in 1 g of peripheral brain tissues of the child models aged between 5 and 8 years is about two times higher than in adult models. This difference is not observed for the child models of children above 8 years old: the maximum SAR in 1 g of peripheral brain tissues is about the same as the one in adult models. Such differences can be explained by the lower thicknesses of pinna, skin and skull of the younger child models

    Full Text Available Abstract Background Muscular dystrophies are chronic diseases manifesting with progressive muscle weakness leading to decreasing activities and participation. To understand the impact on daily life, it is important to determine patients' quality of life. Objective To investigate Health Related Quality of Life (HRQoL of children and adults with muscular dystrophy (MD, and to study the influence of type and severity of MD on HRQoL in adult patients. Methods Age-related HRQoL questionnaires were administered to 40 children (8–17 years, and 67 adult patients with muscular dystrophies. Results Significant differences in HRQoL were found in children and adults with MD compared to healthy controls. Patients with Becker muscular dystrophy reported a better HRQoL on the several scales compared to patients with other MDs. Severity was associated with worse fine motor functioning and social functioning in adult patients. Conclusion This is one of the first studies describing HRQoL of patients with MD using validated instruments in different age groups. The results indicate that having MD negatively influences the HRQoL on several domains.

    Gait analysis on the treadmill and in the overground condition is used both in scientific approaches for investigating the neuronal organisation and ontogenetic development of locomotion and in a variety of clinical applications. We investigated the differences between overground and treadmill locomotion (at identical gait velocity) in 12 adults and 14 children (6-7 years old). During treadmill locomotion the step frequency increased by 7% in adults and 10% in children compared to overground walking, whereas the stride length and the stance phase of the walking cycle decreased. The swing phase, however, increased significantly by 5% in adults and remained unchanged in children. Balance-related gait parameters such as the step width and foot rotation angles increased during treadmill locomotion. The reduction of the step length was found to be stable after 10 min of treadmill walking in most subjects. With regard to the shifted phases of the walking cycle and the changed balance related gait parameters in the treadmill condition, we assume a different modulation of the central pattern generator in treadmill walking, due to a changed afferent input. Regarding the pronounced differences between overground and treadmill walking in children, it is discussed whether the systems generating and integrating different modulations of locomotion into a stable movement pattern have reached full capacity in 6-7 year old children.

    2013-05-01

    Previous scholars have explored various challenges facing children of gay and lesbian individuals, and some have explored the impact of a parent's sexual orientation on the parent-child relationship. However, the impact of religion on the parent-child relationships of adult children with a gay or lesbian parent has been overlooked. In this study, 10 adult children with both a gay or lesbian parent and a heterosexual parent were interviewed and asked to retrospectively explore how religion impacted their parent-child relationships. The following themes emerged from phenomenological analysis of the interviews: (a) family break-up more difficult than the parents' coming out; (b) discovery that parent was gay or lesbian; (c) initial shame over having gay or lesbian parent; (d) positive aspects of having a gay or lesbian parent; (e) redefined relationship with religion; and (f) impact of culture on how gay and lesbian individuals are viewed.

    The management of rheumatic conditions, including those occurring in children, has improved dramatically over the last decade following the introduction of biologic disease-modifying anti-rheumatic drugs (bDMARDS) into the therapeutic arsenal. The benefits have been realised in multiple aspects of disease including signs and symptoms, bone and cartilage destruction, disability and quality of life. Overall, bDMARDS have an acceptable safety profile in the short to medium term in adults and children, however, that following longer term use remains unclear. As these drugs target key signalling molecules and cells of the immune system, adverse events are not unanticipated. In this review we will discuss pulmonary complications of biologic therapies used in the management of rheumatic diseases in both children and adults. PMID:23462434

    2016-08-01

    Reported differences between children and adults with respect to COM horizontal and vertical position to maintain dynamic stability during running deceleration suggest that this relationship may not be as important in children. This study challenged the current dynamic stability paradigm by determining the features of whole body posture that predicted forward velocity and momentum of running gait termination in adults and children. Sixteen adults and 15 children ran as fast as possible and stopped at pre-determined location. Separate regression analyses determined whether COM posterior and vertical positions and functional limb length (distance between COM and stance foot) predicted velocity and momentum for adults and children. COM posterior position was the strongest predictor of forward velocity and momentum in both groups supporting the previously established relationship during slower tasks. COM vertical position also predicted momentum in children, not adults. Higher COM position in children was related to greater momentum; consistent with previously reported differences between children and adults in COM position across running deceleration. COM vertical position was related to momentum but not velocity in children suggesting that strategies used to terminate running may be driven by demands imposed not just by velocity, but also the mass being decelerated.

    Full Text Available Background: Fruit and vegetable consumption is a marker of higher-quality diets; less is known about the contribution of 100% fruit and vegetable juices (FVJ to diet quality. Objective: To explore FVJ consumption patterns in relation to dietary nutrient density among French children (aged 3–14 years old and adults (≥21 years old. Methods: Analyses were based on the nationally representative 2013 CCAF (Comportements et Consommations Alimentaires en France survey of 1930 respondents, stratified by age group, FVJ consumption, and socioeconomic status (SES. Dietary nutrient density was based on the Nutrient Rich Food (NRF9.3 index, adjusted for gender and age. Results: Mean total consumption of fruits and vegetables was 2.6 servings/day for children and 3.8 servings/day for adults. Mean population consumption of FVJ was 83 mL/day for children and 54.6 mL/day for adults, equivalent to 0.4 servings/day and 0.3 servings/day respectively. FVJ consumers had higher quality diets than did non-consumers, after adjusting for covariates. The respective NRF9.3 values were 486.4 ± 4.3 vs. 428.7 ± 7.5 for children and 460.7 ± 4.4 vs. 435.4 ± 4.4 for adults. FVJ consumers had similar or higher intakes of fruits and vegetables than did non-consumers. The socioeconomic gradient for FVJ consumption was much weaker (p < 0.046 than for whole fruit (p < 0.01. Conclusions: In a nationally representative sample of French children and adults, fruit and vegetable consumption fell short of recommended values. Higher FVJ consumption was associated with higher-quality diets and better compliance with the French National Plan for Nutrition and Health (PNNS.

    The objective of this study is to attempt to understand predictors of health among adult migrants from Myanmar to Thailand and predictors of development among their children. EQ5D5L scores and sociodemographic data were obtained among adult household members of children from two schools on the Thai/Myanmar border. Children were administered Ages and Stages questionnaires (ASQs). OLS and logistic regressions were used to examine predictors (e.g., witnessing gunfire) of various outcome measures (e.g., ASQ scores among children). In logistic regression analyses, maternal literacy proved to be a very strong predictor of the child's ASQ communication [17 ASQ points out of 60; 95% confidence interval (CI) 3, 31 points], problem solving (25 points; 95% CI 4, 45 points), and social skills (12 points; 95 % CI 1, 23 points) scores. A lower number of habitants/room predicted significantly better dentition among children [odds ratio (OR) 1.08, 95% CI 1.01, 1.67] and better social skills on the child's ASQ (12 points; 95% CI 1, 23 points). Appliance ownership was a weak predictor of adult health, with those who own a refrigerator having about an 8% higher score on the EQ5D5L (1.08; 95% CI 1.01, 1.16). Finally, parents who witnessed gunfire tended to have children with ASQ scores that were 14 points lower than average in problem solving (95% CI -24, -4). Maternal education programs may have a very large impact on the development of their children. However, identifying those households at greatest need of resources is not a simple task, and will require a more complete census of communities at risk. PMID:25155822

    The current study investigated the time course of cross-linguistic differences in word recognition. We recorded eye movements of German and English children and adults while reading closely matched sentences, each including a target word manipulated for length and frequency. Results showed differential word recognition processes for both developing and skilled readers. Children of the two orthographies did not differ in terms of total word processing time, but this equal outcome was achieved quite differently. Whereas German children relied on small-unit processing early in word recognition, English children applied small-unit decoding only upon rereading-possibly when experiencing difficulties in integrating an unfamiliar word into the sentence context. Rather unexpectedly, cross-linguistic differences were also found in adults in that English adults showed longer processing times than German adults for nonwords. Thus, although orthographic consistency does play a major role in reading development, cross-linguistic differences are detectable even in skilled adult readers.

    Background: Previous research describes spouses and adult children of people with dementia as a homogeneous group using one term: family caregivers. Recent research shows that the needs and experiences of spouses and adult children differ, therefore they cannot be studied as a homogeneous group. Aims: The aim of the study was to describe the shift in existential life situations of adult children of a parent with dementia relocated to nursing homes. Design: This is a qualitative study with an interpretive approach. Methods: Face-to-face interviews were held with 11 adult children aged 48-65 years. The interviews lasted 30–60 minutes and data were analysed using interpretive content analysis. Findings: The adult children described how they experienced their life situation before and after their parents’ relocation. Before relocation they described feelings of powerlessness, loneliness in their responsibilities, loss and guilt. After relocation they had feelings of freedom, ongoing responsibility, living with loss and having a new relationship with death. Conclusion: The most important finding in our study was that adult children developed a different relationship with death than before the parent became affected by dementia. It is essential that healthcare staff understand and address the adult children’s existential life situations and the suffering they are experiencing. Healthcare staff need to be conscious about adult children’s needs for support to address their existential life situations before and after their parents relocate to nursing homes. PMID:27651850

    The use of pneumococcal conjugate vaccines (PCVs) in children has a strong indirect effect on disease rates in adults. When children are vaccinated with PCVs, other serotypes that are not targeted by the vaccine can increase in frequency (serotype replacement) and reduce the direct and indirect benefits of the vaccine. To understand and predict the likely impacts of serotype replacement, it is important to know how patterns in the transmission of serotypes among children relate to disease rates in adults. We used data on pneumococcal carriage and disease from Navajo Nation children and adults collected before and after the routine use of PCVs (1998-2012). Using regression models within a Bayesian framework, we found that serotype-specific carriage and invasiveness (disease incidence divided by carriage prevalence) had similar patterns in children and adults. Moreover, carriage in children, invasiveness in children, and a serotype-specific random intercept (which captured additional variation associated with the serotypes) could predict the incidence serotype-specific pneumococcal disease in adults 18-39 years of age and those 40 years of age or older in the era of routine use of PCVs. These models could help us predict the effects of future pneumococcal vaccine use in children on disease rates in adults, and the modeling approach developed here could be used to test these findings in other settings.

    Adherence to prescribed medication, or patient compliance, was studied over a period of several years in 3 populations with seizure disorders: 2 pediatric (n = 90, n = 211), and 1 adult population (n = 177). Compliance was assessed in several different ways: self-reports and serum levels analyzed for the level/dose ratio as well as the coefficient of variation for each patient. Correlates studied included Health Belief Model variables as well as internal locus of control, social support, knowledge about seizures and other variables. The assessed extent of compliance ranged from 54% to 82% in the various groups. Overall, compliance was related to motivation, value of illness threat reduction, and probability that compliant behavior will reduce the threat. Also related to compliance were some measures of the following types of variables: demographic, structural, attitudinal, provider/patient interaction, social support, experience with the regimen, internal control, and knowledge. A group discussion intervention designed to enhance compliance was implemented and evaluated effectively in the pediatric seizure population. In the adult population, compliance and seizure control both increased over a 2 year follow-up period, but were not significantly related. PMID:3072190

    Language has been assumed to influence categorization for both adults and children but the precise role and potency of linguistic labels in category formation remains open. Here we explore how linguistic labels help fit objects into categories when relevant perceptual information is either ambiguous or inconsistent with the labels. We also ask how the effects of labels compare to those of other types of information such as facts. We presented 4-year-old children and adults with tasks in which they had to categorize a perceptually ambiguous natural-kind stimulus with one of two equidistant standards (Exp. 1 and 2) or group an ambiguous natural-kind stimulus into a category with a perceptually dissimilar standard (Exp. 3). Participants had access to labels (e.g., "This one is a lorp/pim"), observable facts (e.g., "This one has a long/short beak"), or unobservable facts (e.g., "This one drinks water/milk") that grouped the ambiguous stimulus with one of the standards. Both children and adults followed label- and fact-driven category boundaries for perceptually ambiguous stimuli (Exp. 1 and 2), and continued to do so even when the labels or facts pointed to perceptually incongruent categories (Exp. 3). These findings suggest a strong causal role for both labels and facts in categorization and have implications about theories of how categorization develops in children.

    Recommendations limiting the intake of total fat, SFA, MUFA and PUFA have been established in several countries with the aim of reducing the risk of chronic diseases such as CVD. Studies have shown that intakes of total fat and SFA are above desired recommended intake levels across a wide range of age and sex groups. In addition, intakes of PUFA and MUFA are often reported to be less than the desired recommended intake levels. The aims of the present paper are to provide the first data on estimates of current intakes and main food sources of SFA, MUFA and PUFA in Irish children (aged 5-12 years), teenagers (aged 13-17 years) and adults (aged 18-64 years) and to analyse compliance with current dietary recommendations. Data for this analysis were based on the North/South Ireland Food Consumption Survey (n 1379, 18-64 years), the National Children's Food Survey (n 594, 5-12 years) and the National Teen Food Survey (n 441, 13-17 years). Results showed that SFA intakes in Irish children, teenagers and adults are high, with only 6 % of children, 11 % of teenagers and 21 % of adults in compliance with the recommended daily intake. The main food groups that contributed to SFA intakes were whole milk; fresh meat; meat products; biscuits, cakes, buns and pastries; and sugars, confectionery and preserves.

    Four experiments examined variations in children's (chronological age range: 5 years 7 months to 9 years 10 months) and adults' reading strategy as a function of task demands. Experiment 1 found that less skilled readers (mean reading age: 8 years 8 months), though able to make use of rime-based spelling-to-sound correspondences (reading "by analogy"), predominantly used simple grapheme-phoneme-level correspondences in reading isolated unfamiliar items. Skilled children (mean reading age: 11 years 6 months) were more likely to adopt an analogy strategy. Experiments 2 and 3 adopted versions of the "clue word" technique used by U. Goswami (1986, Journal of Experimental Child Psychology, 42, 73-83; 1988, Quarterly Journal of Experimental Psychology, 40A, 239-268) and found a much higher incidence of analogical responding by children of all ages, suggesting that reading strategy is task-dependent. Experiment 4 showed that adults' nonword-reading strategy is determined by list composition, in that grapheme-phoneme correspondences are used more when the list context contains nonwords. It is concluded that both adults and young children exhibit considerable flexibility and task-dependence in the levels of spelling-to-sound correspondence (analogies vs decoding) that they use and that grapheme-phoneme correspondences are preferred when maximum generalization to unfamiliar items is required.

To evaluate the developmental process of auditory habituation, the current study used magnetoencephalography to investigate auditory habituation, dishabituation and stimulus specificity in children and adults and compared the results between age groups. Twenty-nine children (Mage = 9.69 years, SD ± 0.47 and 14 adults (Mage = 29.29 years, SD ± 3.47 participated in the study and passively listened to a habituation paradigm consisting of 100 trains of tones which were composed of five 500Hz tones, one 750Hz tone (dishabituator and another two 500Hz tones, respectively while focusing their attention on a silent movie. Adults showed the expected habituation and stimulus specificity within-trains while no response decrement was found between trains. Sensory adaptation or fatigue as a source for response decrement in adults is unlikely due to the strong reaction to the dishabituator (stimulus specificity and strong mismatch negativity responses. However, in children neither habituation nor dishabituation or stimulus specificity could be found within-trains, response decrement was found across trains. It can be speculated that the differences between children and adults are linked to differences in stimulus processing due to attentional processes. This study shows developmental differences in task-related brain activation and discusses the possible influence of broader concepts such as attention, which should be taken into account when comparing performance in an identical task between age groups.

    There is a growing evidence base on the immediate and short-term effects of adult HIV on children. We provide an overview of this literature, highlighting the multiple risks and resultant negative consequences stemming from adult HIV infection on the children they care for on an individual and family basis. We trace these consequences from their origin in the health and wellbeing of adults on whom children depend, through multiple pathways to negative impacts for children. As effective treatment reduces vertical transmission, the needs of affected children will predominate. Pathways include exposure to HIV in utero, poor caregiver mental or physical health, the impact of illness, stigma and increased poverty. We summarize the evidence of negative consequences, including those affecting health, cognitive development, education, child mental health, exposure to abuse and adolescent risk behaviour, including sexual risk behaviour, which has obvious implications for HIV-prevention efforts. We also highlight the evidence of positive outcomes, despite adversity, considering the importance of recognizing and supporting the development of resilience. This study is the first in a series of three commissioned by President's Emergency Plan for AIDS Relief (PEPFAR)/United States Agency for International Development (USAID), the summary provided here was used to inform a second study which seeks to identify insights from the broader child development field which will help us predict what long-term negative consequences children affected by HIV and AIDS are likely to experience. The third study discusses the design of a model to estimate these consequences. Although comprehensive, the review is often hampered by poor-quality research, inadequate design, small sample sizes and single studies in some areas.

    Full Text Available Abstract Background Cholelithiasis is the gallstone disease (GSD where stones are formed in the gallbladder. The main function of the gallbladder is to concentrate bile by the absorption of water and sodium. GSD has high prevalence among elderly adults. There are three major types of gallstones found in patients, White, Black and Brown. The major chemical component of white stones is cholesterol. Black and brown stones contain different proportions of cholesterol and bilirubin. The pathogenesis of gallstones is not clearly understood. Analysis of the chemical composition of gallstones using various spectroscopic techniques offers clues to the pathogenesis of gallstones. Recent years has seen an increasing trend in the number of cases involving children. The focus of this study is on the analysis of the chemical composition of gallstones from child and adult patients using spectroscopic methods. Methods In this report, we present FTIR spectroscopic studies and fluorescence microscopic analysis of gallstones obtained from 67 adult and 21 child patients. The gallstones were removed during surgical operations at Soroka University Medical Center. Results Our results show that black stones from adults and children are rich in bilirubin. Brown stones are composed of varying amounts of bilirubin and cholesterol. Green stones removed from an adult, which is rare, was found to be composed mainly of cholesterol. Our results also indicated that cholesterol and bilirubin could be the risk factors for gallstone formation in adults and children respectively. Fluorescence micrographs showed that the Ca-bilirubinate was present in all stones in different quantities and however, Cu-bilirubinate was present only in the mixed and black stones. Conclusions Analysis based on FTIR suggest that the composition of black and brown stones from both children and adults are similar. Various layers of the brown stone from adults differ by having varying quantities of

    The normal meniscus undergoes typical developmental changes during childhood, reaching a mature adult appearance by approximately 10 years of age. In addition to recognizing normal meniscal appearances in children, identifying abnormalities - such as tears and the different types of discoid meniscus and meniscal cysts, as well as the surgical implications of these abnormalities - is vital in pediatric imaging. The reported incidence of meniscal tears in adolescents and young adults has increased because of increased sports participation and more widespread use of MRI. This review discusses the normal appearance of the pediatric meniscus, meniscal abnormalities, associated injuries, and prognostic indicators for repair. (orig.)

    Synovial diseases in children can be classified into normal structures as potential sources of pathology (synovial folds: plicae, infrapatellar fat pad clefts); noninfectious synovial proliferation (juvenile idiopathic arthritis, hemophilic arthropathy, lipoma arborescens, synovial osteochondromatosis, pigmented villonodular synovitis, reactive synovitis), and infectious synovial proliferation, deposition disease, vascular malformations, malignancy (including metastasis) and intra-articular/periarticular cysts and cyst-like structures (ganglia). Familiarity with characteristic MR imaging findings of synovial diseases in children and young adults will enable a more confident diagnosis for earlier intervention and directed therapy. The first part of this paper will cover potential pathology of normal synovial structures as well as noninfectious synovial proliferation. (orig.)

    Many people are guided by religious beliefs, but judgments of religiously and secularly motivated individuals remain unclear. We investigated reasoning about religiously versus secularly motivated characters among 5- to 10-year-olds and adults. In Study 1, theist and non-theist children reported similar attitudes toward theists; however, large differences emerged between theist and non-theist adults. Study 2 obtained similar results using a continuous, rather than forced choice, measure of preference. Additionally, Studies 2-3 tested two explanations for the stronger influence of religious background on adults' versus children's responses. Study 2 did not find strong evidence for the theistic majority account, which posits that the greater perceived prevalence of theists as compared with non-theists influenced children's responses more than adults' responses. The results of Study 3 were consistent with the intuition account, which argues that non-theist adults had effortfully overridden the teleological intuitions that may have influenced children's responses in Studies 1-2 and potentially led children to prefer characters whose beliefs were in line with children's own intuitions. The degree to which teleological intuitions persisted implicitly among adults predicted those adults' pro-theist preferences. These findings offer connections between religious judgments and other areas of social cognition, such as social preferences and teleology. PMID:26275836

    Full Text Available The objective of this study was to compare quinolone resistance and gyrA mutations in clinical isolates of Klebsiella pneumoniae and Escherichia coli from Chinese adults who used quinolone in the preceding month and children without any known history of quinolone administration. The antimicrobial susceptibilities of 61 isolates from children and 79 isolates from adults were determined. The mutations in the quinolone resistance-determining regions in gyrA gene were detected by PCR and DNA sequencing. Fluoroquinolone resistance and types of gyrA mutations in isolates from children and adults were compared and statistically analyzed. No significant differences were detected in the resistance rates of ciprofloxacin and levofloxacin between children and adults among isolates of the two species (all P>0.05. The double mutation Ser83→Leu + Asp87→Asn in the ciprofloxacin-resistant isolates occurred in 73.7% isolates from the children and 67.9% from the adults, respectively (P=0.5444. Children with no known history of quinolone administration were found to carry fluoroquinolone-resistant Enterobacteriaceae isolates. The occurrence of ciprofloxacin resistance and the major types of gyrA mutations in the isolates from the children were similar to those from adults. The results indicate that precautions should be taken on environmental issues resulting from widespread transmission of quinolone resistance.

    Studies have established that grown children's problems affect parental well-being, but a dearth of research has addressed daily interactions and biological systems that may underlie these associations. This study examined whether parents have different types of daily interactions with adult children who have problems and whether those interactions are associated with variations in parents' diurnal cortisol rhythms. Middle-aged parents (n=197) reported their interactions with adult children for seven consecutive days and provided saliva, analyzed for cortisol, three times a day (wake, 30 min after wake, bedtime) for four of those days. Parents were more likely to report negative encounters but not less likely to report positive interactions or contact with adult children who suffered from problems. Interactions with adult children who had physical-emotional problems had more immediate same day associations with cortisol whereas interactions with adult children who had lifestyle-behavioral problems had more delayed, or next day associations with cortisol. Daily interactions and their associations with the hypothalamic-pituitary-adrenal-axis may be important mechanisms by which adult children with problems negatively affect parental well-being.

  16. Language proficiency and executive control in proactive interference: evidence from monolingual and bilingual children and adults.

    Two studies are reported in which monolingual and bilingual children (Study 1) and adults (Study 2) completed a memory task involving proactive interference. In both cases, the bilinguals attained lower scores on a vocabulary test than monolinguals but performed the same on the proactive interference task. For the children, bilinguals made fewer intrusions from previous lists even though they recalled the same number of words. For the adults, bilinguals recalled more words than monolinguals when the scores were corrected for differences in vocabulary. In addition, there was a strong effect of vocabulary in which higher vocabulary participants recalled more words irrespective of language group. These results point to the important role of vocabulary in verbal performance and memory. They also suggest that bilinguals may compensate for weaker language proficiency with their greater executive control to achieve the same or better levels of performance as monolinguals.

    The influence of sodium valproate on serum levels of phenobarbital during combination treatment was studied in 29 children and 50 adults with epilepsy. Steady-state drug levels in serum were determined immediately prior to drug administration using immunoenzymatic analysis. The serum level/dose ratio of phenobarbital increased significantly (p less than 0.001) when sodium valproate was added to the treatment. The increase had a mean value of 50.9% in adults and 112.5% in children, suggesting marked interindividual variability in the intensity of the interaction. Almost half of the patients required a decrease in the dose of phenobarbital prescribed. The interaction was more pronounced in patients with high serum levels of phenobarbital, while the dose of phenobarbital and the serum levels and dose of sodium valproate did not seem to affect the extent of the interaction. Close monitoring of the serum levels of phenobarbital is recommended during simultaneous treatment with sodium valproate. PMID:3103264

    Full Text Available The aim of the present study was to record the percentage of children, adults and elderly women in Greece meeting food and micronutrient intake recommendations. Additionally, the present study was aiming to identify the main food contributors of micronutrient intakes and assess the degree up to which meeting food intake recommendations also ensures micronutrient intake adequacy. Dietary intake data from three studies conducted in Greece (on 9–13-year-old children; 40–60-year-old adults; and 50–75-year-old women were used to estimate mean intakes, the percentages of subjects meeting food and nutrient intake recommendations and the contribution of six core food groups to nutrient intake adequacy. The present study showed that more than 50% of children, adults and elderly women were failing to consume the recommended portions of vegetables, dairy and grains. Furthermore, children and adults consuming the recommended portions of individual core food groups had significantly lower percentages of inadequate micronutrient intakes compared to their counterparts not meeting food intake recommendations (p < 0.05. Nevertheless, even among those consuming the recommended portions from a specific core food group, the recommended intake of the corresponding micronutrient (for which this food group is the main contributor was not always met. Indicatively, 18.2%–44.1% and 4.2%–7.0% of the populations under study were not meeting calcium and vitamin C intake recommendations, although they were consuming the recommended portions of dairy and fruits, respectively. In conclusion, these findings highlight the importance for public health policy makers to take all necessary initiatives to support the population in achieving the recommended intakes from all core food groups, but also emphasize on food variety to ensure adequate intake for all micronutrients.

  9. A dietary-wide association study (DWAS of environmental metal exposure in US children and adults.

    Directory of Open Access Journals (Sweden)

    Matthew A Davis

    Full Text Available A growing body of evidence suggests that exposure to toxic metals occurs through diet but few studies have comprehensively examined dietary sources of exposure in US populations.Our goal was to perform a novel dietary-wide association study (DWAS to identify specific dietary sources of lead, cadmium, mercury, and arsenic exposure in US children and adults.We combined data from the National Health and Nutrition Examination Survey with data from the US Department of Agriculture's Food Intakes Converted to Retail Commodities Database to examine associations between 49 different foods and environmental metal exposure. Using blood and urinary biomarkers for lead, cadmium, mercury, and arsenic, we compared sources of dietary exposure among children to that of adults.Diet accounted for more of the variation in mercury and arsenic than lead and cadmium. For instance we estimate 4.5% of the variation of mercury among children and 10.5% among adults is explained by diet. We identified a previously unrecognized association between rice consumption and mercury in a US study population--adjusted for other dietary sources such as seafood, an increase of 10 g/day of rice consumption was associated with a 4.8% (95% CI: 3.6, 5.2 increase in blood mercury concentration. Associations between diet and metal exposure were similar among children and adults, and we recapitulated other known dietary sources of exposure.Utilizing this combination of data sources, this approach has the potential to identify and monitor dietary sources of metal exposure in the US population.

    2006-05-01

    Full Text Available Adult humans, infants, pre-school children, and non-human animals appear to share a system of approximate numerical processing for non-symbolic stimuli such as arrays of dots or sequences of tones. Behavioral studies of adult humans implicate a link between these non-symbolic numerical abilities and symbolic numerical processing (e.g., similar distance effects in accuracy and reaction-time for arrays of dots and Arabic numerals. However, neuroimaging studies have remained inconclusive on the neural basis of this link. The intraparietal sulcus (IPS is known to respond selectively to symbolic numerical stimuli such as Arabic numerals. Recent studies, however, have arrived at conflicting conclusions regarding the role of the IPS in processing non-symbolic, numerosity arrays in adulthood, and very little is known about the brain basis of numerical processing early in development. Addressing the question of whether there is an early-developing neural basis for abstract numerical processing is essential for understanding the cognitive origins of our uniquely human capacity for math and science. Using functional magnetic resonance imaging (fMRI at 4-Tesla and an event-related fMRI adaptation paradigm, we found that adults showed a greater IPS response to visual arrays that deviated from standard stimuli in their number of elements, than to stimuli that deviated in local element shape. These results support previous claims that there is a neurophysiological link between non-symbolic and symbolic numerical processing in adulthood. In parallel, we tested 4-y-old children with the same fMRI adaptation paradigm as adults to determine whether the neural locus of non-symbolic numerical activity in adults shows continuity in function over development. We found that the IPS responded to numerical deviants similarly in 4-y-old children and adults. To our knowledge, this is the first evidence that the neural locus of adult numerical cognition takes form early in

    Currently, there is some debate about whether to use Comprehensive System norms (CS; Exner, 2003 ) or the Composite International Reference Values (CIRV; Meyer, Erdberg, & Shaffer, 2007 ) when interpreting Rorschach Inkblot Method (RIM; Rorschach, 1921 ) protocols administered with the CS method. The goal of this study is to assist clinicians in making this decision by providing information about the effects of choosing one option or the other. Accordingly, this research evaluates the effects of using the CS versus CIRV norms with children, adolescents, and adults. First, we identified 43 variables for which the CS and the CIRV for children and adolescents differ from each other by at least a Cohen's d value of .50. Next, we evaluated whether these divergent variables are the same as those previously identified as divergent for the adult population. Results showed that for both children and adolescents, as well as for adults, relying on CS norms versus CIRV would result in interpretations that are more pathological in terms of (a) perception and thinking, (b) psychological resources and cognitive and emotional abilities, and (c) representations of human relationships. A discussion on the clinical effects of using one versus the other set of norms follows. PMID:26829463

    Jean Piaget underestimated the cognitive capabilities of infants, preschoolers, and elementary schoolchildren, and overestimated the capabilities of adolescents and even adults which are often biased by illogical intuitions and overlearned strategies (i.e., "fast thinking" in Daniel Kahneman's words). The crucial question is now to understand why, despite rich precocious knowledge about physical and mathematical principles observed over the last three decades in infants and young children, older children, adolescents and even adults are nevertheless so often bad reasoners. We propose that inhibition of less sophisticated solutions (or heuristics) by the prefrontal cortex is a domain-general executive ability that supports children's conceptual insights associated with more advanced Piagetian stages, such as number-conservation and class inclusion. Moreover, this executive ability remains critical throughout the whole life and even adults may sometimes need "prefrontal pedagogy" in order to learn inhibiting intuitive heuristics (or biases) in deductive reasoning tasks. Here we highlight some of the discoveries from our lab in the field of cognitive development relying on two methodologies used for measuring inhibitory control: brain imaging and mental chronometry (i.e., the negative priming paradigm). We also show that this new approach opens an avenue for re-examining persistent errors in standard classroom-learning tasks. PMID:24994993

  19. Dissociation between face perception and face memory in adults, but not children, with developmental prosopagnosia

    Full Text Available Cognitive models propose that face recognition is accomplished through a series of discrete stages, including perceptual representation of facial structure, and encoding and retrieval of facial information. This implies that impaired face recognition can result from failures of face perception, face memory, or both. Studies of acquired prosopagnosia, autism spectrum disorders, and the development of normal face recognition support the idea that face perception and face memory are distinct processes, yet this distinction has received little attention in developmental prosopagnosia (DP. To address this issue, we tested the face perception and face memory of children and adults with DP. By definition, face memory is impaired in DP, so memory deficits were present in all participants. However, we found that all children, but only half of the adults had impaired face perception. Thus, results from adults indicate that face perception and face memory are dissociable, while the results from children provide no evidence for this division. Importantly, our findings raise the possibility that DP is qualitatively different in childhood versus adulthood. We discuss theoretical explanations for this developmental pattern and conclude that longitudinal studies are necessary to better understand the developmental trajectory of face perception and face memory deficits in DP.

    The purpose of this investigation was to evaluate the effect of a lower body positive pressure support system on the joint kinematics and activity of the lower extremity antigravity musculature of adults and children during walking. Adults (age = 25 ± 4 years) and children (age = 13 ± 2 years) walked at a preferred speed and a speed that was based on the Froude number, while 0-80% of their body weight was supported. Electrogoniometers were used to monitor knee and ankle joint kinematics. Surface electromyography was used to quantify the magnitude of the vastus lateralis and gastrocnemius muscle activity. There were three key findings: (1) The lower extremity joint angles and activity of the lower extremity antigravity muscles of children did not differ from those of adults. (2) The magnitude of the changes in the lower extremity joint motion and antigravity muscle activity was dependent upon an interaction between body weight support and walking speed. (3) Lower body positive pressure support resulted in reduced activation of the antigravity musculature, and reduced range of motion of the knee and ankle joints.

    Stroke is an abrupt onset of both focal and global neurological deficits secondary to a vascular event lasting more than 24 h and with a vascular background as its only cause. It can be triggered by a rupture of a blood vessel, aneurysm (hemorrhagic stroke, HS), thrombosis or embolisms (ischemic stroke, IS). In developed countries, it is the third most common cause of death in the adult population. Stroke in children is a rare disorder with a reported frequency of about 3 cases per 100,000 children per year. The history of acute brain ischemia is burdened with neurological complications such as motor impairment, speech impairment and intellectual delay. Moreover, in children after AIS seizures and epilepsy are also quite common. Stroke is a heterogeneous disorder; its risk factors in adults are well known, however, in pediatrics, in more than 20% cases, the cause of stroke is impossible to determine. Due to the fact that stroke usually arises as a consequence of the cerebral thrombosis, many of the mechanisms responsible for its occurrence can be considered as risk factors. We have reviewed the recent case-control studies conducted on pediatric patients regarding biochemical risk factors such as elevated levels of homocysteine, fibrinogen, protein C, protein S, antithrombin III, lipoprotein(a), cholesterol and its fractions, and compared them with the results obtained from adult patients.

    Full Text Available It is generally believed that the infant's microbiota is established during the first 1-2 years of life. However, there is scarce data on its characterization and its comparison to the adult-like microbiota in consecutive years.To characterize and compare the intestinal microbiota in healthy young children (1-4 years and healthy adults from the North Carolina region in the U.S. using high-throughput bacterial phylogenetic microarray analysis.Detailed characterization and comparison of the intestinal microbiota of healthy children aged 1-4 years old (n = 28 and healthy adults of 21-60 years (n = 23 was carried out using the Human Intestinal Tract Chip (HITChip phylogenetic microarray targeting the V1 and V6 regions of 16S rRNA and quantitative PCR.The HITChip microarray data indicate that Actinobacteria, Bacilli, Clostridium cluster IV and Bacteroidetes are the predominant phylum-like groups that exhibit differences between young children and adults. The phylum-like group Clostridium cluster XIVa was equally predominant in young children and adults and is thus considered to be established at an early age. The genus-like level show significant 3.6 fold (higher or lower differences in the abundance of 26 genera between young children and adults. Young U.S. children have a significantly 3.5-fold higher abundance of Bifidobacterium species than the adults from the same location. However, the microbiota of young children is less diverse than that of adults.We show that the establishment of an adult-like intestinal microbiota occurs at a later age than previously reported. Characterizing the microbiota and its development in the early years of life may help identify 'windows of opportunity' for interventional strategies that may promote health and prevent or mitigate disease processes.

    Rapid increases in the proportion of older adults in the population present major challenges to policy-makers worldwide. Using a nationally representative sample from the PAPFAM survey in Lebanon, this study examined the living arrangements of older adults (aged > or = 65 years), and their correlates, with a focus on co-residence with married children. Of 1774 older adults 17.1% co-resided with their married children: 28.1% of the 559 unmarried (widowed/divorced/single) and 11.3% of the 1071 married older adults. Among both the married and unmarried, the likelihood of co-residence was significantly lower in regions outside the capital and decreased with increasing socioeconomic status. Among the unmarried elderly, co-residence with a married child was also significantly associated with increasing age and availability of sons, as well as presence of a vascular disorder and speech problems. While solitary living has traditionally been the focus for policy-makers, older people living with a married child may also be a vulnerable group. PMID:24684101

    When the police have no suspect, they may ask an eyewitness to construct a facial composite of that suspect from memory. Faces are primarily processed holistically, and recently developed computerized holistic facial composite systems (e.g., EFIT-V) have been designed to match these processes. The reported research compared children aged 6-11 years with adults on their ability to construct a recognizable EFIT-V composite. Adult constructor's EFIT-Vs received significantly higher composite-suspect likeness ratings from assessors than children's, although there were some notable exceptions. In comparison to adults, the child constructors also overestimated the composite-suspect likeness of their own EFIT-Vs. In a second phase, there were no differences between adult controls and constructors in correct identification rates from video lineups. However, correct suspect identification rates by child constructors were lower than those of child controls, suggesting that a child's memory for the suspect can be adversely influenced by composite construction. Nevertheless, all child constructors coped with the demands of the EFIT-V system, and the implications for research, theory, and the criminal justice system practice are discussed. PMID:25705795

    Full Text Available Studies on the collagen system of the human myocardium are still limited compared to those on small laboratory animals. The aim of this work was to observe the collagen tissue of the myocardium of the human heart as a function of age. The types of collagen, as well as the density of collagen tissue and the diameter of collagen fibrils, were examined. Fragments of the left ventricular wall from 15 hearts, 5 from children, 5 from young adults, and 5 from elderly individuals, were analyzed by using the Picrosirius-polarization method and by transmission electron microscopy (TEM. The results showed the presence of collagen type III and collagen type I, both in the endomysium and perimysium of the 3 groups studied. Measurements of collagen content in myocardial tissue displayed that both endomysial and perimysial collagen increase in number and thickness in the adult and elderly. These histochemical results coincided with the observations obtained with the electron microscope in showing an increase in the number of collagen fibrils with a large diameter in the adult and elderly hearts. The present results on cardiac collagen may be important for assessing the pathogenesis of several cardiopathies in the hearts of children, young adults, and the elderly.

    Purpose This study was performed to determine if there is an age-related specificity in the response of muscle protein metabolism to severe burn injury during acute hospitalization. This is a retrospective analysis of previously published data. Methods: Nineteen adult and 58 pediatric burn-injured patients (age 43.3 ± 14.3 vs. 7.2 ± 5.3 years, adult vs. children) participated in stable isotope [ring-2H5]phenylalanine (Phe) infusion studies. Femoral arterial and venous blood samples and muscle biopsy samples were collected throughout the study. Data are presented as means ± standard deviation (SD). A p value less than 0.05 was considered statistically significant. Results Muscle net protein balance (NB) was higher in children (adult vs. children, -43 ± 61 vs. 8 ± 68 nmol Phe/min/100 ml leg volume, p < 0.05). Muscle protein fractional synthesis rate (FSR) was higher in children (adult vs. children, 0.11 ± 0.05 vs. 0.16 ± 0.10 %/h, p < 0.05). Leg muscle protein breakdown was not different between the groups (adult vs. children, 179 ± 115 vs. 184 ± 124 nmol Phe/ min/100 ml leg volume, p < 0.05; synthesis rate was 134 ± 96 and 192 ± 128 nmol Phe/min/100 ml leg volume in adults and children, respectively (p = 0.07). Age significantly correlated with muscle protein NB (p = 0.01) and FSR (p = 0.02); but not with breakdown (p = 0.67) and synthesis (p = 0.07) rates measured by using a three-pool model. Conclusion In burn injury, the muscle protein breakdown may be affected to the same extent in adults and children, whereas synthesis may have age-related specificities, resulting in a better but still low NB in children.

    We measured visually-cued motor responses in two developmentally separate groups of children and compared these responses to a group of adults. We hypothesized that if post-movement beta rebound (PMBR) depends on developmentally sensitive processes, PMBR will be greatest in adults and progressively decrease in children performing a basic motor task as a function of age. Twenty children (10 young children 4-6 years; 10 adolescent children 11-13 years) and 10 adults all had MEG recorded during separate recordings of right and left index finger movements. Beta band (15-30 Hz) event-related desynchronization (ERD) of bi-lateral sensorimotor areas was observed to increase significantly from both contralateral and ipsilateral MI with age. Movement-related gamma synchrony (60-90 Hz) was also observed from contralateral MI for each age group. However, PMBR was significantly reduced in the 4-6 year group and, while more prominent, remained significantly diminished in the adolescent (11-13 year) age group as compared to adults. PMBR measures were weak or absent in the youngest children tested and appear maximally from bilateral MI in adults. Thus PMBR may reflect an age-dependent inhibitory process of the primary motor cortex which comes on-line with normal development. Previous studies have shown PMBR may be observed from MI following a variety of movement-related tasks in adult participants - however, the origin and purpose of the PMBR is unclear. The current study shows that the expected PMBR from MI observed from adults is increasingly diminished in adolescent and young children respectively. A reduction in PMBR from children may reflect reduced motor cortical inhibition. Relatively less motor inhibition may facilitate neuronal plasticity and promote motor learning in children.

    The purpose of this study was to evaluate a procedure for measurement of specific airway resistance (sRaw) by whole body plethysmography in young awake children accompanied by an adult. sRaw was measured by a single-step procedure, omitting the measurement of the thoracic gas volume. The frequency...... dependency of sRaw was investigated and the accuracy of simulating body temperature, atmospheric pressure and saturation with water vapour (BTPS) conditions by electronic compensation was assessed. One hundred and thirty one children with asthma were studied. In 57 children (mean (SD) age 5.6 (1.8) yrs) who...... performed measurements with and without an accompanying adult, the mean value of sRaw was 1.45 (0.36) and 1.44 (0.38) kPa x s, respectively, with a mean difference of 0.008 (0.152) kPa x s, and mean within-subject coefficients of variations (CV) of 8% and 10%, respectively.

    Nitrite intake from the consumption of cured meat and tap water was estimated for Finnish children of 1, 3 and 6 years as well as Finnish adults of 25-74 years. Nitrite content in the foods was measured by capillary electrophoresis, and was then used together with individual food consumption data from the FINDIET 2007 and DIPP studies in a stochastic exposure assessment by a Monte Carlo Risk Assessment (MCRA) program. Nitrite intake from additive sources and tap water was assessed, and more than every 10th child between the ages 3 and 6 years was estimated to have a nitrite intake exceeding the acceptable daily intake (ADI) of nitrite. The high exposure levels were caused by frequent consumption of large portions of sausages, up to 350 g day(-1) or 750 g in 3 days, among the children. Median nitrite intake from cured meat was 0.016, 0.040, 0.033 and 0.005 mg kg(-1) body weight day(-1) for children of 1, 3 and 6 years and adults, respectively. Bayesian estimation was employed to determine safe consumption levels of sausages and cold cuts for children, and these results gave rise to new national food consumption advice. PMID:26609554

    Research suggests that children may interfere with single parents' romantic experiences. Although both male and female single parents face these challenges, they have stronger associations with the romantic satisfaction of single mothers as compared to single fathers. The two current studies examined aspects of attractiveness and dating across various dimensions for both younger single women and men, with and without children. Results of Study 1 indicated interactive effects of target gender and parental status on perceptions of both attractiveness and dating potential. Results of Study 2 indicated differential ratings on multiple dimensions (i.e., attractiveness, stress, motivation for dating, and positive qualities) of younger single adults on the basis of gender, parental status, and the number of children single parents were reported as having. Implications for importance of social support and difficulty of repartnering are discussed. PMID:24837530

    Forty-five adults with the acquired immunodeficiency syndrome (AIDS) and their 45 spouses, 109 children, and 29 household contacts were studied for evidence of heterosexual, perinatal, and household spread of human T-cell lymphotropic virus type III (HTLV-III) infection. Of the 45 spouses enrolled, 26 (58%) had antibody to HTLV-III, including 12 (71%) of 17 male spouses and 14 (50%) of 28 female spouses. Of the 12 seropositive male spouses, nine were seropositive at enrollment and three had seroconversion. Of the 14 seropositive female spouses, four were seropositive at enrollment and ten seroconverted. Lack of barrier contraceptive use and oral sex were associated with seroconversion. Of the 109 children enrolled, 15 had AIDS or an AIDS-related illness, two had evidence of passive transfer of maternal antibodies, and two had HTLV-III infection acquired outside the household. None of the 90 seronegative children seroconverted. Of 29 household contacts studied, nondeveloped antibody to HTLV-III.

    Objectives Quick service restaurant (QSR) television advertisements for children’s meals were compared with adult advertisements from the same companies to assess whether self-regulatory pledges for food advertisements to children had been implemented. Methods All nationally televised advertisements for the top 25 US QSR restaurants from July 1, 2009 to June 30, 2010 were obtained and viewed to identify those advertising meals for children and these advertisements were compared with adult advertisements from the same companies. Content coding included visual and audio assessment of branding, toy premiums, movie tie-ins, and depictions of food. For image size comparisons, the diagonal length of the advertisement was compared with the diagonal length of salient food and drink images. Results Almost all of the 92 QSR children’s meal advertisements that aired during the study period were attributable to McDonald’s (70%) or Burger King (29%); 79% of 25,000 television placements aired on just four channels (Cartoon Network, Nickelodeon, Disney XD, and Nicktoons). Visual branding was more common in children’s advertisements vs. adult advertisements, with food packaging present in 88% vs. 23%, and street view of the QSR restaurant present in 41% vs. 12%. Toy premiums or giveaways were present in 69% vs. 1%, and movie tie-ins present in 55% vs. 14% of children’s vs. adult advertisements. Median food image diagonal length was 20% of the advertisement diagonal for children’s and 45% for adult advertisements. The audio script for children’s advertisements emphasized giveaways and movie tie-ins whereas adult advertisements emphasized food taste, price and portion size. Conclusions Children’s QSR advertisements emphasized toy giveaways and movie tie-ins rather than food products. Self-regulatory pledges to focus on actual food products instead of toy premiums were not supported by this analysis. PMID:24015250

    Previous neuroimaging research with adults suggests that the medial prefrontal cortex (MPFC) and the medial posterior parietal cortex (MPPC) are engaged during self-knowledge retrieval processes. However, this has yet to be assessed in a developmental sample. Twelve children and 12 adults (average age = 10.2 and 26.1 years, respectively) reported whether short phrases described themselves or a highly familiar other (Harry Potter) while undergoing functional magnetic resonance imaging. In both children and adults, the MPFC was relatively more active during self- than social knowledge retrieval, and the MPPC was relatively more active during social than self-knowledge retrieval. Direct comparisons between children and adults indicated that children activated the MPFC during self-knowledge retrieval to a much greater extent than adults. The particular regions of the MPPC involved varied between the two groups, with the posterior precuneus engaged by adults, but the anterior precuneus and posterior cingulate engaged by children. Only children activated the MPFC significantly above baseline during self-knowledge retrieval. Implications for social cognitive development and the processing functions performed by the MPFC are discussed.

    The 7-valent pneumococcal conjugate vaccine (PCV7) produced a significant herd protection in unvaccinated adult population mostly because of pneumococcus carriage decrease in vaccinated children. It is not known if the 13-valent pneumococcal vaccine can give similar effect on adults. Aims of the work were to evaluate whether the 6 additional serotypes are present in nasopharynx of children and serotype distribution in invasive pneumococcal infections (IPD) in adults. Realtime-PCR was used to evaluate pneumococcal serotypes in adults with confirmed IPD and in nasopharyngeal swabs (NP) from 629 children not vaccinated or vaccinated with PCV7 and resident in the same geographical areas. Two hundred twenty-one patients (116 males, median 67.9 years) with IPD were studied (pneumonia n = 103, meningitis n = 61 sepsis n = 50, other n = 7). Two hundred twelve were serotyped. The most frequent serotypes were 3, (31/212; 14.6%), 19A, (19/212; 9.0%), 12 (17/212; 8.0%), 7F, (14/212; 6.6%). In NP of children, the frequency of those serotypes causing over 50% of IPD in adults was very low, ranging from 0.48% for serotype 7F to 7.9% for serotype 19A. On the other side serotype 5, very frequent in NP (18.7%) caused children NP. We suggest that herd protection obtainable with the additional 6 serotypes included in PCV13 may be more limited than that demonstrated with PCV7 in the past. In order to reduce the burden of disease in adults, adults should be offered a specific vaccination program with highly immunogenic PCV.

    2011-01-01

    The purpose of this study was to examine the effect of participation in a music-based intergenerational music program on cross-age interactions and cross-age attitudes of elementary-age children and older adults, and older adults' psychosocial well-being. Twenty-one children in the 4th grade volunteered to participate in the experimental (n = 12) or control (n = 9) group. Twenty-six older adults from a retirement living facility also volunteered to participate in the experimental (n = 14) or control (n = 12) group. Ten 30-min music sessions occurred in which participants engaged in singing, structured conversation, moving to music, and instrument playing interventions. Data analysis of cross-age interactions revealed that the interventions "structured conversation" and "moving to music" were more effective in eliciting interaction behaviors than the interventions "singing" and "instrument playing." Standardized measures revealed that children's attitudes towards older adults improved, though not significantly so, after participation in the intergenerational program. Results of biweekly post-session questionnaires revealed a decrease in negative descriptions of older adults and an increase in positive descriptions of older adults--suggesting a more positive view towards aging. Results revealed that older adults' attitudes towards children improved significantly after their participation in the intergenerational program. While standardized measures revealed that older adults did not perceive a significant improvement in their psychosocial well-being, their bi-weekly post-session questionnaires showed they perceived increased feelings of usefulness and other personal benefits from the intergenerational interactions. Suggestions for future research, the utility of varied measurement instruments, and implications for practice are discussed. PMID:22506301

    Full Text Available BACKGROUND: Iodine deficiency disorders (IDD are widespread in China. Presently, IDD have been put under control by Universal Salt Iodisation (USI in China; however, there is a lack of evidence on whether the iodine status in adults, pregnant women and lactating women is optimal. This study was therefore conducted to assess the iodine nutrition and thyroid function of children, adults, pregnant women and lactating women residing in areas where the USI program is fully established. DESIGN: Six areas were selected according to the geographical regions in China. In each of these areas, we selected 4 distinct groups of subjects (children, adults, pregnant women and lactating women in regions where the coverage rate of iodised salt was more than 95% and the levels of iodine and fluoride in drinking water were less than or equal to 10 µg/L and 1 mg/L, respectively. We tested the iodine content of salt, urinary iodine (UI, free thyroxin (FT4, thyrotropin (TSH, thyroglobulin (Tg, thyroglobulin antibody (Tg-Ab and antimicrosomal antibody (TM-Ab in the 4 groups, and examined the thyroid volume in children. RESULTS: The median urinary iodine (MUI concentrations were 271.4 μg/L, 260.2 μg/L, 205.9 μg/L and 193.9 μg/L in children, adults, pregnant women and lactating women, respectively; MUI in children and adults were more than adequate. The goitre prevalence (GP in children was 6.70%. The odds ratios (OR of subclinical hypothyroidism in the Tg-Ab- or TM-Ab-positive groups were 3.80, 7.65, 2.01 and 7.47 for children, adults, pregnant women and lactating women, respectively, compared with the negative groups. CONCLUSIONS: The iodine status in children and adults is above the requirement, we should reduce their iodine intake. Subclinical hypothyroidism easily occurs in the Tg-Ab or TM-Ab positive groups.

    Drawing on a panel study of parents and children, we investigate linkages between parents' marital quality and adult children's attitudes toward a range of family issues, including premarital sex, cohabitation, lifelong singlehood, and divorce. We hypothesize that parents' marital quality will be negatively related to children's support for these behaviors in adulthood and that parents' marital quality will condition the intergenerational transmission of attitudes toward these issues.

    Holmlund, Helena; Rainer, Helmut; Siedler, Thomas

    2013-06-01

    The aim of this study is to estimate the causal effect of family size on the proximity between older mothers and adult children by using a large administrative data set from Sweden. Our main results show that adult children in Sweden are not constrained by sibship size in choosing where to live: for families with more than one child, sibship size does not affect child-mother proximity. For aging parents, however, having fewer children reduces the probability of having at least one child living nearby, which is likely to have consequences for the intensity of intergenerational contact and eldercare.

    2012-01-01

    Full Text Available Only a few studies have investigated asthma morbidity in Canadian Aboriginal children. In the present study, data from the 2006 Aboriginal Peoples Survey were used to determine the prevalence and risk factors for asthma in Canadian Aboriginal children six to 14 years of age and adults 15 to 64 years of age living off reserve. The prevalence of asthma was 14.3% in children and 14.0% in adults. Children and adults with Inuit ancestry had a significantly lower prevalence of asthma than those with North American Indian and Métis ancestries. Factors significantly associated with ever asthma in children included male sex, allergy, low birth weight, obesity, poor dwelling conditions and urban residence. In adults, factors associated with ever asthma varied among Aboriginal groups; however, age group, sex and urban residence were associated with ever asthma in all four Aboriginal groups. The prevalence of asthma was lower in Aboriginal children and higher in Aboriginal adults compared with that reported for the Canadian population. Variation in the prevalence of and risk factors for asthma among Aboriginal ancestry groups may be related to genetic and environmental factors that require further investigation.

    Full Text Available Jean Piaget underestimated the cognitive capabilities of infants, preschoolers, and elementary schoolchildren, and overestimated the capabilities of adolescents and even adults which are often biased by illogical intuitions and overlearned strategies (i.e., fast thinking in Daniel Kahneman’s words. The crucial question is now to understand why, despite rich precocious knowledge about physical and mathematical principles observed over the last three decades in infants and young children, older children, adolescents and even adults are nevertheless so often bad reasoners. We propose that inhibition of less sophisticated solutions (or heuristics by the prefrontal cortex is a domain-general executive ability that supports children’s conceptual insights associated with more advanced Piagetian stages, such as number conservation and class inclusion. Moreover, this executive ability remains critical throughout the whole life and even adults may sometimes need prefrontal pedagogy in order to learn inhibiting intuitive heuristics (or biases in deductive reasoning tasks. Here we highlight some of the discoveries from our lab in the field of cognitive development relying on two methodologies used for measuring inhibitory control: brain imaging and mental chronometry (i.e., the negative-priming paradigm. We also show that this new approach opens an avenue for re-examining persistent errors in standard classroom-learning tasks.

  14. Integration of audio-visual information for spatial decisions in children and adults.

    2016-09-01

    In adults, decisions based on multisensory information can be faster and/or more accurate than those relying on a single sense. However, this finding varies significantly across development. Here we studied speeded responding to audio-visual targets, a key multisensory function whose development remains unclear. We found that when judging the locations of targets, children aged 4 to 12 years and adults had faster and less variable response times given auditory and visual information together compared with either alone. Comparison of response time distributions with model predictions indicated that children at all ages were integrating (pooling) sensory information to make decisions but that both the overall speed and the efficiency of sensory integration improved with age. The evidence for pooling comes from comparison with the predictions of Miller's seminal 'race model', as well as with a major recent extension of this model and a comparable 'pooling' (coactivation) model. The findings and analyses can reconcile results from previous audio-visual studies, in which infants showed speed gains exceeding race model predictions in a spatial orienting task (Neil et al., 2006) but children below 7 years did not in speeded reaction time tasks (e.g. Barutchu et al., 2009). Our results provide new evidence for early and sustained abilities to integrate visual and auditory signals for spatial localization from a young age. PMID:26190579

    Although the research on caregiving and caregivers has been extensive, there have been few studies on the cultural context and meaning of African American caregiving in relation to HIV illness. Many Black feminists have argued that African American women experience a world different from those who are not Black and that failure to take account of race, class, and gender is paramount in an attempt to authentically portray the lives of African American women. This study argues that rural African American culture and experiences of racism and discrimination in the rural South shaped the responses of mothers when their adult children developed HIV illness. The study employed the ethnographic techniques of participant observation and in-depth interviews with 14 rural, poor, African American mothers who cared for adult children with HIV illness. Analysis of the data identified patterns of resistance that mothers employed throughout the caregiving experience. Mothers resisted labels and other controlling images that they believed marginalized them and negated what was happening to their children. Mothers used culturally patterned behaviors to protect their families and resist the stigma of HIV/AIDS. PMID:10530083

  16. Differences in the sensitivity of children and adults to carciogenic substances - literature study

    International Nuclear Information System (INIS)

    A literature study was undertaken to investigate whether children are more sensitive to carcinogenic effects than adults. This question is especially important for regulatory decisions for situations with shorter than lifetime exposure. Adequate human data is scare except for ionizing radiation, where there is good evidence for a higher sensitivity of children for breast cancer, leukemia and thyroid cancer from epidemiological studies of japanese atom bomb survivors and tumor patients. For chemical substances main evidence comes from animal studies, which show for several substances (e.g. vinyl chloride, nitrosamines, polycyclic aromatic hydrocarbons, 2-acetylaminofluorene, benzidine, aflatoxin B1, cycasin, urethane) high incidences of tumors in the juvenile organisms whereas under comparable exposure conditions low numbers or no tumors were observed in adult animals. All of the mentioned substances are genotoxic carcinogens and mechanistic studies point towards the importance of high cell division rates in target organs of the juvenile organism which in combination with genotoxic activity leads to tumor development. Concerning nongenotoxic carcinogens there are data for saccharin which show that tumor incidence is higher when exposure periods include the period between birth and weaning. For other substances there is negative evidence under similar conditions. In conclusion there is ample evidence for a high sensitivity of the young towards some genotoxic carcinogens and therefore even less than lifetime exposures of children towards these substances may lead to a high carcinogenic risk.

    Pesticide handlers and pet owners who use products such as shampoos and dips and insecticide-impregnated collars to treat and control fleas on companion animals are exposed to a variety of active ingredients. Chlorpyrifos exposures of adults and children were measured using urine biomonitoring following use of over-the-counter products on dogs. Age and gender-specific measurements of urinary 3, 5, 6-trichloro-2-pyridinol (TCPy) revealed modest elevations of biomarker excretion following shampoo/dips. Smaller TCPy increments were measured following application of impregnated dog collars. The extent of indoor activity and potential pet contact were important determinants of urine biomarker level. Children without direct pet contact excreted more TCPy following collar application. Pet collars may be a source of indoor surface contamination and human exposure. Children excreted up to 4 times more TCPy than adults when urine volumes were adjusted using age-specific creatinine excretion levels. Although chlorpyrifos is no longer used in the United States in pet care products, results of this research provide perspective on the extent of human exposure from similar pet care products. These pilot studies demonstrated that pet care products such as insecticidal shampoos and dips and impregnated collars may expose family members to low levels of insecticide relative to toxic levels of concern.

    BACKGROUND: Violence in families affects children. Exposure to violence is seen as child abuse. Figures show that about one third of children exposed to violence become victim or perpetrator in their adult life: known as intergenerational transmission. Violence also affects sexual and reproductive health. To prevent problems in adult life, children need help and support.

Additionally, the use of sophisticated diagnostic tools and screening modalities has increased over recent years. Because of these factors, cancer is being diagnosed more frequently during the child-rearing years. Sociodemographic and cancer-related information on families and minor (0–18 years and young adult (YA (19–25 years children experiencing parental cancer is scarce, but this information is vital for healthcare initiatives aimed toward those potentially adversely affected. Therefore, the aim of this study was to describe features of families and minor and YA children affected by parental cancer in a nationwide population.Methods: Complete Norwegian birth cohort data were obtained from national registries. Descriptive prevalence and incidence statistics were collected for parents and minor and YA children. Logistic regression models were used to assess factors likely to influence parental death.Results: Every year around 0.3% of all families with children under the age of 18 years encounter parental cancer, and 3.1% of minors and 8.4% of YAs have a parent who has been diagnosed with cancer. This study found skin, breast, testicular, and colorectal cancers were the most common forms of cancer diagnosed. The sociodemographic features of those affected were fairly similar to those of the general population. One in five children experienced parental death from cancer; parental death was more often paternal than maternal and was most common in parents diagnosed with leukemia or brain, colorectal, and lung tumors. Deaths are uncommon among parents without cancer.Conclusion: Adequate assistance for minor and YA children affected by parental cancer requires knowledge of their number and characteristics.

    2012-09-01

    Full Text Available In South Africa, abacavir (ABC is currently recommended as part of first- and second-line antiretroviral therapy (ART for HIV-positive paediatric patients. Concerns about overprescribing of the drug, particularly to adults, led to an analysis of ABC use in public sector ART programmes. We investigated current prescription of the drug to adults and children accessing ART in 4 public sector programmes across Gauteng Province, South Africa. ABC was almost exclusively prescribed to children initiating ART and adults requiring regimen changes due to drug toxicities. Patterns of ABC use among HIV-positive paediatric patients followed national ART treatment guidelines on the application of the drug. Although ABC is commonly used in the private sector for adults, the current national ART treatment guidelines for adults and adolescents should include ABC as an alternative to standard first- or second-line ART.

    Rapid eye movement sleep is composed of phasic and tonic periods, two distinguishable microstates in terms of arousal thresholds and sensory processing. Background electroencephalogram oscillations are also different between periods with (phasic state) and periods without (tonic state) eye movements. In Study 1, previous findings analysing electroencephalogram spectral power in phasic and tonic rapid eye movement sleep were replicated, and analyses extended to the high gamma range (52-90 Hz). In Study 2, phasic and tonic spectral power differences within a group of 4-8-year-old children were examined. Based on the polysomnographic data of 20 young adults, the phasic state yielded increased delta and theta power in anterior sites, as well as generally decreased high alpha and beta power in comparison to the tonic state. Moreover, phasic periods exhibited greater spectral power in the lower and the higher gamma band. Interestingly, children (n = 18) exhibited a different pattern, showing increased activity in the low alpha range during phasic periods. Moreover, during phasic in contrast to tonic rapid eye movement sleep, increased low and high gamma and enhanced low gamma band power emerged in anterior and posterior regions, respectively. The current findings show that spectral activity within the high gamma range substantially contributes to the differences between phasic and tonic rapid eye movement sleep, especially in adults. Moreover, the current data underscore the heterogeneity of rapid eye movement sleep, and point to marked differences between young adults and children regarding phasic/tonic electroencephalogram spectral power. These results suggest that the differentiation between phasic and tonic rapid eye movement periods undergoes maturation.

    The objective of the present work is to assess the current breakfast model in different age groups: children between the ages of 6 and 12 years (n = 54); adolescents between the ages of 13 and 17 years (n = 174); and adults, older than 18 years of age (n = 252). For this a questionnaire has been designed that follows the standards of that used for a similar study by our team in 1984 on a sample of 1350 individuals. The modified and amplified questionnaire included open and closed questions about: the omission of breakfast and its causes, foods that are a part of breakfast, the most frequent types and the variations, the role of the second breakfast, the number of fasting hours since dinner, the time spent of breakfast, and the subjective opinion regarding the importance or not of having breakfast. 98.95% answer yes to the question do you have breakfast, but only 9% eats a nutritionally correct breakfast, one defined as that breakfast that supplies 20% of the total energy and includes foods from at least four different groups. All the children included some form of milk product in their breakfast. The adolescents consumed the lowest proportion of cereals (19.4%) and the highest proportion of pastries (24.2%). The percentage of adults who drink coffee with milk (57%) and sugar (37.7%) is significantly higher than that it the other two groups. Bread (37.7%), pastries (28.3%) and cookies (26.1%) are the solid foods eaten most by the adults. The children spend the longest time on breakfast. 35.9% of the sample varies their breakfast, 43.1% never does, and 21% does so sometimes. The average time elapsed between dinner and breakfast is 10.5 +/- 1.2 hours. It is advisable to have a more nutritionally balanced breakfast, including different foods from at least four groups, and including a greater variety in the menus. PMID:9780752

    The Test of Language Competence-Expanded Edition (TLC-E) was administered to children and adults with a diagnosis of autism spectrum disorder (ASD). Relative to controls, those with ASD were less competent on a range of TLC-E tasks. No differences were found for either child or adult ASD groups on any of the TLC-E measures when re-classified as Asperger syndrome (AS) and high functioning autism (HFA) using DSM-IV language criterion. Hierarchical cluster analyses of individuals with ASD identified subgroups within the spectrum. The use of developmental language history as an identifying marker in autism is questioned. The findings suggest that comprehensive language assessments on individuals with ASD can provide clinically relevant information regarding the heterogeneity of language skills within the autistic spectrum.

    Hypercalcaemia is a common metabolic complication of malignant disease often requiring emergency intervention. Although it is more frequently associated with solid tumours, malignancy-associated hypercalcaemia (MAH) is seen in a significant number of patients with blood diseases. Its association with myeloma and adult T-cell leukaemia\\/lymphoma is well recognized but the incidence of hypercalcaemia in other haematological neoplasms, affecting adults and children, is less clearly defined. Haematologists need to be familiar with the clinical manifestations of, the differential diagnosis to be considered and the most effective management strategies that are currently available for MAH. The key components of management of MAH include aggressive rehydration, specific therapy to inhibit bone resorption and, crucially, treatment of the underlying malignancy. Bisphosphonates have revolutionized the management of MAH over the last 20 years, however the elucidation of molecular pathways implicated in MAH is facilitating the development of more targeted approaches to treatment.

    The squalene oil-in-water emulsion MF-59 adjuvant was developed initially to enhance the immunogenicity of influenza vaccines in populations such as children and adults with known suboptimal response. Developed in the 1990s, it was initially licensed in Europe for use in seasonal influenza vaccine in the elderly. Since that time, both Avian and p2009H1N1 vaccines have also been developed. Overall, more than 30,000 individuals have participated in clinical trials of MF-59 adjuvanted vaccine and more than 160 million doses of licensed vaccine have been administered. Safety and effectiveness data from clinical trials and observation studies attest to the safety of MF-59 and to its ability to enhance the effectiveness of influenza vaccines in children and the elderly.

Mean DMFT was 1.9 in 18-year......-olds and 6.3 in 35-44-year-olds and figures were higher for women than men. In adults, no differences in caries experience were found by location whereas the caries index was significantly affected by ethnic group and occupation. CPI score 2 (gingivitis and calculus) was dominant for all ages: 6 years (58...

    Few previous studies have addressed exercise capacity in patients with corrected congenital heart disease (CHD) and significant anatomical residua. The aim of this study was to determine the aerobic fitness and peak cardiac function of patients with corrected CHD with complete or incomplete repairs, as determined by resting echocardiography. Children, adolescents and young adults (heart defect had decreased aerobic fitness, with evidence of impaired peak cardiac function and lower pulmonary perfusion. Patients that had undergone a complete repair had decreased aerobic fitness attributed only to deconditioning. These newly identified differences explain why in previous studies, the lowest fitness was seen in patients with the most hemodynamically significant heart malformations.

    In-depth interviews about the “empty nest” were conducted with 57 HIV-positive mothers of late adolescent/early adult children. Empty nest worries included: (1) identity loss, (2) loss of social support, (3) financial insecurity, (4) worsening of physical health, and (5) death/dying. Hopes included: (1) self-improvement, (2) change of life focus, (3) travel, (4) romantic partners, and (5) familial ties. Respondents’ HIV/AIDS status colored their thoughts/feelings about the empty nest; some wo...

  14. The computed tomographic appearance of cerebral cysticercosis in adults and children

    International Nuclear Information System (INIS)

    The computed tomographic (CT) scans of 45 patients (30 adults, 15 children) with cerebral cysticercosis were reviewed. These patients had undergone complete diagnostic evaluations including skin tests, laboratory tests, plain skull radiography, radionuclide brain scanning, CT, and cerebral angiography. All of these tests were unrewarding except CT and the indirect hemagglutination tests on the serum. A classification of cerebral cysticercosis based on the location of the lesions in the brain and the CT appearance was developed. Cerebral cysticercosis can be diagnosed by CT findings when there is also a history of seizures and of the patient having lived in an area where the disease is endemic

  16. Structural and functional rich club organization of the brain in children and adults.

    Directory of Open Access Journals (Sweden)

    David S Grayson

    Full Text Available Recent studies using Magnetic Resonance Imaging (MRI have proposed that the brain's white matter is organized as a rich club, whereby the most highly connected regions of the brain are also highly connected to each other. Here we use both functional and diffusion-weighted MRI in the human brain to investigate whether the rich club phenomena is present with functional connectivity, and how this organization relates to the structural phenomena. We also examine whether rich club regions serve to integrate information between distinct brain systems, and conclude with a brief investigation of the developmental trajectory of rich-club phenomena. In agreement with prior work, both adults and children showed robust structural rich club organization, comprising regions of the superior medial frontal/dACC, medial parietal/PCC, insula, and inferior temporal cortex. We also show that these regions were highly integrated across the brain's major networks. Functional brain networks were found to have rich club phenomena in a similar spatial layout, but a high level of segregation between systems. While no significant differences between adults and children were found structurally, adults showed significantly greater functional rich club organization. This difference appeared to be driven by a specific set of connections between superior parietal, insula, and supramarginal cortex. In sum, this work highlights the existence of both a structural and functional rich club in adult and child populations with some functional changes over development. It also offers a potential target in examining atypical network organization in common developmental brain disorders, such as ADHD and Autism.

  17. [Schizophrenia in children and adolescents: relevance and differentiation from adult schizophrenia].

    Schizophrenia in childhood is rare (point prevalence schizophrenia rises dramatically in adolescence, and its prevalence is estimated at 0.23% in the age between 13 and 18 years. The findings from clinical, neuroimaging, neuropsychological and neurobiological studies support that there is a substantial continuity between childhood, adolescent and adult schizophrenia, despite developmental differences. For this reason, the DSM-IV and ICD-10 criteria for schizophrenia are valid for all age spectrums, but their application in earlier ages is difficult, and the particular developmental characteristics of each developmental phase should be taken into consideration. The differential diagnosis of childhood and adolescent schizophrenia, especially from pervasive developmental disorders, affective disorders with psychotic features and some forms of atypical psychosis, poses similar difficulties. The clinical picture is characterized predominantly by auditory hallucinations, delusions which are less complex than in adults, and flat or inappropriate affect. Formal thought disorder and disorganized behavior are common. Premorbid neurodevelopmental impairments, including language, motor and social deficits, are more frequent and more pronounced in persons that will later on develop schizophrenia during childhood or adolescence, compared to adulthood. Furthermore, the emergence of prodromal symptoms, prior to the main psychotic symptoms, is common. The onset of the main psychotic symptoms is usually insidious, and delay in diagnosis and treatment is common, with adverse consequences on the course and outcome of the disorder. The onset of overt psychosis is characterized by a marked deterioration from previous level of functioning in the vast majority of children and adolescents, and an adverse course and outcome is reported in approximately 50-60% of cases. Compared to adult schizophrenia, childhood schizophrenia manifests higher familial predisposition and possibly greater

    It is still in doubt whether the standard-dose growth hormone (GH) used in Japan (0.5 IU/kg/week, 0.167 mg/kg/week) for growth hormone deficiency is effective for achieving significant adult height improvement in non-growth hormone deficient (non-GHD) short children. We compared the growth of GH-treated non-GHD short children with that of untreated short children to examine the effect of standard-dose GH treatment on non-GHD short children.

    Several large-scale studies have reported the presence of an inverse relationship between bone mineral density (BMD) and bone marrow adipose tissue (BMAT) in adults. We aim to determine if there is an inverse relationship between pelvic volumetric BMD (vBMD) and pelvic BMAT in children and to compare this relationship in children and adults. Pelvic BMAT and bone volume (BV) was evaluated in 181 healthy children (5-17yr) and 495 healthy adults (≥18yr) with whole-body magnetic resonance imaging (MRI). Pelvic vBMD was calculated using whole-body dual-energy X-ray absorptiometry to measure pelvic bone mineral content and MRI-measured BV. An inverse correlation was found between pelvic BMAT and pelvic vBMD in both children (r=-0.374, pBMAT as the independent variable, being a child or adult neither significantly contribute to the pelvic BMD (p=0.995) nor did its interaction with pelvic BMAT (p=0.415). The inverse relationship observed between pelvic vBMD and pelvic BMAT in children extends previous findings that found the inverse relationship to exist in adults and provides further support for a reciprocal relationship between adipocytes and osteoblasts.

    Full Text Available Introduction: Chickenpox is very contagious childhood disease, which occurs due to varicella-zoster virus (VZV primaryinfection. Disease in healthy children resolves usually without complications, but risk of complication is much higherin adults and immunocompromised hosts. The goal of this study was to determine different clinical and epidemiologicalcharacteristics, laboratory features, clinical course, and outcome of chickenpox in children and adults.Material and methods: The descriptive study was conducted at the Department of Infectious Diseases, Clinical Centerin Sarajevo, Bosnia-Herzegovina. The study included 120 patients chosen randomly. We compared their clinical andepidemiological characteristics, laboratory investigations, complications and the outcome of the disease.Results: Age of patients was in range from one to 48 years. Male patients prevailed in both groups (65% in adults,52% in children. Hospitalization rate was 10.7/100,000 inhabitants. Positive contact with chickenpox was confirmed in80% adults and 82% children. Dominating symptoms were fever, rash and muscle aches. Levels of C-reactive protein,erythrocyte sedimentation rates (ESR and fibrinogen levels were elevated in both groups, while thrombocytopenia waspresented in 33% of adults and 3% of children. Adults had complications in 83.3% and their hospitalization rate waslonger compared to children (11.5 days vs. 9.5 days, p<0.001.Conclusions: Chickenpox is a potentially severe illness in adult patients. Introduction of active immunization in Bosnia-Herzegovina should be considered to prevent severe forms of chickenpox.

    2011-08-01

    We compared arterial elasticity in American Indian and Caucasian children, adolescents, and young adults, and we assessed whether demographic, body composition, and ambulatory activity measures were predictive of arterial elasticity within each group. Fifty-one American Indians and 66 Caucasians between the ages of 8 and 30 years were assessed on large artery elasticity index, small artery elasticity index, body fat percentage, and daily ambulatory activity during 7 consecutive days. American Indians had a higher percentage of body fat than Caucasians (p = 0.002), whereas daily ambulatory activity measures were similar (p > 0.05). American Indians had a 16% lower large artery elasticity index (p = 0.007) and a 19% lower small artery elasticity index (p cadence (p = 0.001), fat-free mass (p cadence for 30 continuous minutes (p = 0.009), race (p = 0.005), and average cadence (p = 0.049). Between 8 and 30 years of age, elasticity means for the large and small arteries is lower in American Indians than in Caucasians. A smaller difference was observed in children, with a trend to a much larger difference in young adults. Furthermore, greater fat-free mass and higher daily ambulatory cadence are associated with higher arterial elasticity in both American Indians and Caucasians. PMID:21828174

  2. Development of dental charts according to tooth development and eruption for Turkish children and young adults

    International Nuclear Information System (INIS)

    In this study, we aimed to develop dental charts for Turkish children and young adults of both genders within the age group of 4.5-22.5 years according to tooth mineralization and eruption in a format similar to that proposed by AlQahtani et al. In total, 753 digital panoramic radiographs from 350 males and 403 females were assessed. The permanent teeth were evaluated according to the classification system described by Demirjian et al. The eruption stage was assessed with Bengston's system, which was modified by AlQahtani et al at four points. Teeth generally developed earlier in females than in males. This was particularly notable in the age group of 5-14 years. However, this difference was usually visible in only one stage, not in all teeth. It has been determined that the mixed dentition period ended with the shedding of the second deciduous molars in both genders. The dental charts presented here included information that could be beneficial to dental clinicians in making appropriate diagnosis and planning orthodontic and surgical procedures. These charts also provided datasets for preliminary dental age estimation in Turkish children and young adults.

    Two processes, serial and hierarchical, are generally opposed to account for grammatical encoding in language production. In a developmental perspective, the question addressed here is whether the subject-verb agreement during writing is computed serially, once the words are linearly ordered in the sentence, or hierarchically, as soon as the number features are determined in a hierarchical frame. Adults and children from 3rd to 5th grades were requested to listen to sentences with built-in prepositional phrases or relative clauses and to transcribe them as quickly as possible. A serial hypothesis assumes that subject-verb agreement errors should be equally frequent with both preambles because each has the same length separating the subject head noun and the main verb. Conversely, according to a hierarchical view, errors should be more frequent with a prepositional phrase because the syntactic distance between the subject and the verb is greater than with a relative clause. The results revealed a main effect of the preamble manipulated in 5th graders and adults, but not in 3rd graders. These data were in favor of a hierarchical processing in older writers and a serial one in younger children. However, in 3rd grade, we assumed that the potential serial account was a result of the resource constraint on writing more than of a real serial processing of the agreement. PMID:16050444

    In most Western countries, clinical management of disorders of sex development (DSD), including ambiguous genitalia, begins at diagnosis soon after birth. For many Indonesian patients born with ambiguous genitalia, limited medical treatment is available. Consequently, affected individuals are raised with ambiguous genitalia and atypical secondary sex characteristics. We investigated gender identity and gender role behavior in 118 Indonesian subjects (77 males, 41 females) with different types of DSD in comparison with 118 healthy controls matched for gender, age, and residential setting (rural, suburban, or urban). In Study 1, we report on methodological aspects of the investigation, including scale adaptation, pilot testing, and determining reliability and validity of measures. In Study 2, we report on gender development in 60 children (42 boys, 18 girls), 24 adolescents (15 boys, 9 girls), and 34 adults (19 men, 15 women) with DSD. The majority of participants with DSD never received any medical or surgical treatment prior to this study. We observed a gender change in all age groups, with the greatest incidence in adults. Among patients who changed, most changed from female to male, possessed a 46,XY karyotype, and had experienced significant masculinization during life. Gender identity confusion and cross-gender behavior was more frequently observed in children with DSD raised as girls compared to boys. Puberty and associated masculinization were related to gender problems in individuals with 46,XY DSD raised female. An integrated clinical and psychological follow-up on gender outcome is necessary prior to puberty and adulthood.

    Older parents of an adult child coping with a mental disorder that is expressed by violent deviant behavior face significant parenting challenges. The purpose of this article is to explore the ways older parents exposed to abuse by their adult children with mental disorder (ACMD) perceived their child's violent deviant behavior along the life course. In a qualitative-phenomenological study, 16 parents aged 58 to 90 were interviewed in depth. Three major themes emerged: (a) ongoing total care for the child's needs along the life course, (b) constructions and perceptions of the child through the years-Parents perceived their children over two continua, reflecting their experience of the child's deviant behavior: the child as more harmed versus more harmful, the child as normative versus pathological-and (c) the parent's emotional world toward the harmed-harmful child. The findings enable a deeper understanding of the various ways in which parents cope with living with deviant behaviors of their ACMD. Hence, this study can serve as a framework for developing tailored and differential intervention methods. PMID:25854589

  6. Clinical study of inhaled aerosols total deposition in healthy adults and children

    International Nuclear Information System (INIS)

    Inhalation is the first step towards respiratory tract intake of chemical and radioactive toxics. Particle deposition in human airways has been described by several authors as showing large individual variations. This study intends to contribute to assess this variability limits especially with reference to age. The method used is basically a measurement of retention, by difference between inhaled and exhaled air concentrations, of inert monodispersed aerosols, during controlled breathing. Particles of 1, 2, 3 μm MMAD (polystyrene latex) are measured in size and concentration by laser velocimetry. A Fleish pneumotachograph is used for controlling respiratory parameters. Healthy subjects, male and female, undergo the test at various tidal volumes, frequencies and flow rates, simulated resting and exercising ventilation; their respiratory function is also explored in a very complete way. 20 adults between 23 and 54 years have been tested in order to assess the laboratory reference values. 25 children, 8 under the age of 8 years, and 17 between 8 and 15 years, have been tested in a similar way. Compared to adults, children, especially under 8 years, have different total deposition mean values, higher for spontaneous and quiet controlled breathing, lower for exercising controlled breathing. Total deposition is dependent on particle size, higher for 2 than for 1 μm MMAD, but also, on lung volume, V.C., T.L.C., F.R.C., to which it is inversely proportional

  8. Musculoskeletal Proportionality, Biomechanical Considerations, and Their Contribution to Movement in Adults and Children.

    O'Brien, Thomas D

    2016-05-01

    The musculoskeletal system grows greatly throughout maturation. When trying to explain differences in strength, power and movement patterns between adults and children many pediatric exercise scientists will assume that this growth is proportional in all dimensions and structures. This article examines the evidence underpinning these assumptions, and considers how changes in fascicle, muscle, tendon and joint proportions may contribute to maturation-induced changes in physical performance. There are only a small number of studies to draw upon, but they consistently indicate that 1) growth changes the functional design of muscles, so that they become better at producing large forces at slow speeds but less able to achieve large length changes or high velocities; 2) the skeleton appears to grow somewhat proportionally before puberty, but this changes throughout adolescence, meaning the moment arm about which the muscle acts does not remain proportional to muscle length or the external moment arm about which joint work acts on the external world. In combination these results show that external measures of whole body or joint performance do not reflect the actual internal muscle function similarly in children and adults. Since our purpose should be to explain and not just describe maturation-induced changes in performance, greater efforts are needed to understand the internal "engine" driving our movement. This necessitates more detailed, longitudinal and dynamically loaded studies of the structure and function of the muscles and their interaction with the skeleton throughout maturation. PMID:27137167

    Establishing the reliability of event-related potentials is critical for future applications to biomarker development and clinical research. Few studies have examined the reliability of the contingent negative variation (CNV), and only in adults. The current study explored test-retest reliability of the visually evoked CNV and its embedded components, the O-wave and the E-wave, in children (7-13 years) and young adults (19-28 years) during a visual Go/No-Go task over 1-2 weeks. Test-retest reliability of the components was moderate for children, and low-to-moderate for adults. These findings were in contrast to previous work with adults showing moderate-to-high reliability of the auditory-evoked CNV. PMID:27145115

    This cultural-developmental interview study examined moral reasoning in relation to religious culture (evangelical, mainline Protestants), age (children, adolescents, adults), and moral issue (public, private; N = 120). Compared to adolescents and adults, children used more Ethic of Autonomy and less Ethic of Community reasoning. With age, differences between religious cultures became pronounced. Mainline adults invoked an Ethic of Divinity for private issues. Evangelical adolescents and adults used this ethic frequently, but more for public than private issues. These and other findings indicate that evangelical and mainline Protestants diverge on what should be society's moral lingua franca, and cast new and nuanced light on America's "culture wars." Results furthermore highlight comodulation of development and culture that requires life course research on moral reasoning.

    Contaminated site cleanup decisions may require estimation of dermal exposures to soil. Telephone surveys represent one means of obtaining relevant activity pattern data. The initial Soil Contact Survey (SCS-I), which primarily gathered information on the activities of adults, was conducted in 1996. Data describing adult behaviors have been previously reported. Results from a second Soil Contact Survey (SCS-II), performed in 1998-1999 and focused on children's activity patterns, are reported here. Telephone surveys were used to query a randomly selected sample of U.S. households. A randomly chosen child, under the age of 18 years, was targeted in each responding household having children. Play activities as well as bathing patterns were investigated to quantify total exposure time, defined as activity time plus delay until washing. Of 680 total survey respondents, 500 (73.5%) reported that their child played outdoors on bare dirt or mixed grass and dirt surfaces. Among these "players," the median reported play frequency was 7 days/week in warm weather and 3 days/week in cold weather. Median play duration was 3 h/day in warm weather and 1 h/day in cold weather. Hand washes were reported to occur a median of 4 times per day in both warm and cold weather months. Bath or shower median frequency was seven times per week in both warm and cold weather. Finally, based on clothing choice data gathered in SCS-I, a median of about 37% of total skin surface is estimated to be exposed during young children's warm weather outdoor play. PMID:11140435

    Numerous studies have indicated that for phthalates, the intake of contaminated foods is the most important exposure pathway for the general population. Up to now, data on dietary phthalate intake are scarce and - to the authors' knowledge - not available for the Belgian population. Therefore, the purpose of this study was: (1) to assess the long-term intake of the Belgian population for eight phthalates considering different exposure scenarios (benzylbutyl phthalate (BBP); di-n-butyl phthalate (DnBP); dicyclohexyl phthalate (DCHP); di(2-ethylhexyl) phthalate (DEHP); diethyl phthalate (DEP); diisobutyl phthalate (DiBP); dimethyl phthalate (DMP), di-n-octyl phthalate (DnOP)); (2) to evaluate the intake of BBP, DnBP, DEP and DEHP against tolerable daily intake (TDI) values; and (3) to assess the contribution of the different food groups to the phthalate intake. The intake assessment was performed using two Belgian food consumption databases, one with consumption data of preschool children (2.5 to 6.5 years old) and another of adults (≥15 years old), combined with a database of phthalate concentrations measured in over 550 food products sold on the Belgian market. Phthalate intake was calculated using the 'Monte Carlo Risk Assessment' programme (MCRA 7.0). The intake of DEHP was the highest, followed by DiBP. The intake of BBP, DnBP and DEP was far below the TDI for both children and adults. However, for DEHP, the 99th percentile of the intake distribution of preschoolers in the worst case exposure scenario was equal to 80% of the TDI, respectively. This is not negligible, since other exposure routes of DEHP exist for children as well (e.g. mouthing of toys). Bread was the most important contributor to the DEHP intake and this may deserve further exploration, since the origin of this phthalate in bread remains unclear.

    Full Text Available OBJECTIVE: As almost any version of percutaneous nephrolithotomy (PCNL was safely and efficiently applied for adults as well as children without age being a limiting risk factor, the aim of the study was to compare the different characteristics as well as the efficacy, outcome, and safety of the pediatric and adult patients who had undergone mini-PCNL (MPCNL in a single institution. METHODS: We retrospective reviewed 331 renal units in children and 8537 renal units in adults that had undergone MPCNL for upper urinary tract stones between the years of 2000-2012. The safety, efficacy, and outcome were analyzed and compared. RESULTS: The children had a smaller stone size (2.3 vs. 3.1 cm but had smilar stone distribution (number and locations. The children required fewer percutaneous accesses, smaller nephrostomy tract, shorter operative time and less hemoglobin drop. The children also had higher initial stone free rate (SFR (80.4% vs. 78.6% after single session of MPCNL (p0.05. Both groups had low rate of high grade Clavien complications. There was no grade III, IV, V complications and no angiographic embolization required in pediatric group. One important caveat, children who required multiple percutaneous nephrostomy tracts had significant higher transfusion rate than in adults (18.8% vs. 4.5%, p = 0.007. CONCLUSIONS: This contemporary largest-scale analysis confirms that the stone-free rate in pediatric patients is at least as good as in adults without an increase of complication rates. However, multiple percutaneous nephrostomy tracts should be practiced with caution in children.

    A non-radioactive method that uses reverse-phase high performance liquid chromatography is described for the determination of thiopurine methyltransferase (E.C. 2.1.1.67) activity in human erythrocytes. The method is based on the direct quantitation of 6-methyl-mercaptopurine produced from 6-mercaptopurine by crude erythrocyte lysates. The method is accurate and reliable and suitable for diagnostic use. Activity values in control adults ranged from 5 to 32 pmol/h/mg haemoglobin. The activity in the erythrocytes of adult males was significantly higher compared to females (21 +/- 5 and 15 +/- 8 pmol/h/mg haemoglobin, respectively). The activity measured in the erythrocytes of children (22 +/- 5 pmol/h/mg haemoglobin) did not show any significant difference compared to adults. Thiopurine methyltransferase activity was measured in a female patient with systemic sclerosis who developed severe bone marrow depression after treatment with azathioprine and allopurinol. Activity (6.3 +/- 0.5 pmol/h/mg haemoglobin) was found in the lowest range of controls thus supporting the hypothesis that it could be responsible for increased azathioprine cytotoxicity.

    British Sign Language (BSL) signers use a variety of structures, such as constructed action (CA), depicting constructions (DCs), or lexical verbs, to represent action and other verbal meanings. This study examines the use of these verbal predicate structures and their gestural counterparts, both separately and simultaneously, in narratives by deaf children with various levels of exposure to BSL (ages 5;1 to 7;5) and deaf adult native BSL signers. Results reveal that all groups used the same types of predicative structures, including children with minimal BSL exposure. However, adults used CA, DCs, and/or lexical signs simultaneously more frequently than children. These results suggest that simultaneous use of CA with lexical and depicting predicates is more complex than the use of these predicate structures alone and thus may take deaf children more time to master.

    Full Text Available How sensory organization for postural control matures in children is not clear at this time. The present study examined, in children aged 7 to 11 and in adults, the postural control modifications in quiet standing when somatosensory inputs from the ankle were disturbed. Since the reweighting of sensory inputs is not mature before 10, we hypothesized that postural stability was more affected in children than in adults when somatosensory inputs were altered and that this postural instability decreased as age increased during childhood. 37 children aged 7 to 11 years and 9 adults participated in the experiments. The postural task was a semi-tandem position with the right foot in front of the left one. Postural performance was measured by means of a force platform. Two experimental conditions were presented to the participants to maintain quiet standing: With or without altered somatosensory inputs (i.e., with or without ankles vibration. Results showed that postural stability--and thus how the reweighting process of the visual/somatosensory inputs matured--increased non-monotonically between 7 years of age and adult age: There was a linear improvement of postural stability from 7 to 10, followed by a more steady behaviour between 10 and 11 and then postural stability increased to reach the adults' level of performance.

  17. Radiation exposure of children and young adults during X-ray investigations - experience and conclusions

    International Nuclear Information System (INIS)

    After discussing the existing regulations for radiation protection of patients in the field of pediatric X-ray diagnostics in the GDR the use of the effective dose equivalent HE and the medium dose equivalent HM for the determination of radiation exposure to children is shortly discussed. Using computer tomography images to determine the position and size of organs of children, and the data from measured depth dose distributions, the exposure related to the entrance dose caused by frequent X-ray examinations was calculated. Measurements of entrance doses at 3 pediatric hospitals for all examination types and the determination of the frequency of X-ray radiographies at 10 hospitals and 10 smaller diagnostic departments were used to calculate the per caput and the collective dose equivalents in the different age groups. Altogether the per caput dose equivalent of the children amounts to approximately 30% of the corresponding value for adults. As a conclusion, the following measures for the further reduction of radiation exposure are proposed: (1) technical measures like fixation of patients, shielding of organs, quality assurance, (2) elaboration of legal regulations, e.g. of a decree on the performance of pediatric X-ray examinations, and (3) training and continued education. Only by these means an appropriate indication (justification) and an efficient reduction of radiation exposure (optimization) can be achieved. (author)

  18. Radiation dose to infants, children and adults in X-ray diagnostic radiology-in the case of plain radiography

    International Nuclear Information System (INIS)

    The objective of this study was to evaluate radiation doses to infant, child and adult patients undergoing various types of plain radiography and to compare the doses among them. The doses were measured using newborn, 6-year-child and adult anthropomorphic phantoms, in which photodiode dosimeters were implanted at various tissue and organ positions. Measured doses were used to evaluate organ and effective doses. Organ doses obtained in various types of radiography were lower than 0.7 mGy for adults, 0.3 mGy for children and 0.2 mGy for infants, excepting lens dose of approximately 1 mGy in adult head radiography, where the doses for children and infants lowered to 1/2-1/3 of the doses for adults. Effective doses in various types of head radiography for adults, children and infants were in identical levels in a range of 5-30 μSv. In chest, abdomen and hip-joint radiography, effective doses of 0.02-0.11 mSv for children and 0.02-0.08 mSv for infants were identical to or in a fraction of the doses for adults of 0.06-0.15 mSv. In adult head and spinal radiography, effective doses by International Commission of Radiological Protection (ICRP) Publication 60 lowered respectively to 1/6-1/9 and 1/3-1/9 of the doses listed in United Nations Scientific Committee on the Effects of Atomic Radiation (UNSCEAR) 2000.

    2016-04-01

    The purpose of the present study was to investigate the coordination pattern and coordination variability (intra-subject and inter-subject) in children and adults during vertical countermovement jumps. Ten children (mean age: 11.5±1.8years) and ten adults (mean age: 26.1±4.9years) participated in the experiment. Lower body 3D-kinematics and kinetics from both legs were obtained during 9 vertical jumps of each subject. Coordination pattern and coordination variability of intra-limb and inter-limb coupling were established by modified vector coding and continuous relative phase. The adult group jumped higher and with less performance variability compared to the children. Group differences were mainly observed in the right-left foot coupling. The intra-subject coordination variability was higher in coupling of proximal segments in children compared to adults. No group differences were observed in inter-subject variability. Based on these results, it was concluded that the same movement solutions were available to both age groups, but the children were less able to consistently utilize the individually chosen coordination pattern. Thus, this ability appears to be developed through normal ontogenesis. PMID:26724430

    The study examined top-down attention modulation of bottom-up processing in children and adults under conditions of varying bottom-up stimulus demands. Voiced and unvoiced consonant-vowel syllables were used in a dichotic-listening situation to manipulate the strength of the bottom-up stimulus-driven right ear advantage when subjects were instructed to focus attention on, and report, either the left or right ear stimulus. We predicted that children would differ from adults in their ability to use attention to modulate a lateralized ear advantage, and particularly when there was a conflict between the direction of the bottom-up ear advantage and the direction of the top-down attention instruction. Thirty children and 30 adults were presented with dichotic presentations of consonant-vowel syllables. The results showed that the voicing manipulation affected the strength of the ear advantage, and that the children performed significantly below the adults when the voicing parameter caused a strong conflict between bottom-up and top down processing. Thus, children seem to lack the cognitive flexibility necessary to modulate a stimulus-driven bottom-up ear advantage, particularly in situations where right ear advantage (REA) is enhanced by the acoustic properties of the stimuli and attentional demands require a left ear shift. It is suggested that varying the stimulus demands in a dichotic-listening situation may be a novel way to study cognitive development. PMID:18608228

    This article is available open access through the publisher’s website at the link below. During submaximal cycling, children demonstrate a different distribution between muscular and non-muscular (gravitational and motion-dependent) forces when compared with adults. This is partly due to anthropometric differences. In this study, we tested the hypothesis that during maximum power cycling, children would construct the task (in terms of the distribution between muscular and non-muscular peda...

  4. The influence of intersensory discrepancy on visuo-haptic integration is similar in 6-year-old children and adults

    Directory of Open Access Journals (Sweden)

    2014-01-01

    Full Text Available When participants are given the opportunity to simultaneously feel an object and see it through a magnifying or reducing lens, adults estimate object size to be in-between visual and haptic size. Studies with young children, however, seem to demonstrate that their estimates are dominated by a single sense. In the present study, we examined whether this age difference observed in previous studies, can be accounted for by the large discrepancy between felt and seen size in the stimuli used in those studies. In addition, we studied the processes involved in combining the visual and haptic inputs. Adults and 6-year old children judged objects that were presented to vision, haptics or simultaneously to both senses. The seen object length was reduced or magnified by different lenses. In the condition inducing large intersensory discrepancies, children’s judgments in visuo-haptic conditions were almost dominated by vision, whereas adults weighted vision just by 40%. Neither the adults’ nor the children’s discrimination thresholds were predicted by models of visuo-haptic integration. With smaller discrepancies, the children’s visual weight approximated that of the adults and both the children’s and adults' discrimination thresholds were well predicted by an integration model, which assumes that both visual and haptic inputs contribute to each single judgment. We conclude that children integrate seemingly corresponding multisensory information in similar ways as adults do, but focus on a single sense, when information from different senses is strongly discrepant.

    Male and female college students were presented with a photograph labeled as a 5-yr.-old boy or girl and heard statements attributed to the child. They then rated the child on sex-role traits and responded to open-ended questions about the child. The primary findings involved sex of child by sex of adult interactions on ratings of independence and leadership: in both cases, same-sex children were rated higher than opposite-sex children. There was also some evidence that women having high contact with children rated the child more extremely on opposite-sex traits than did those with little contact. PMID:740494

    2011-12-01

    Full Text Available Abstract Background Vitamin/mineral supplements are among the most commonly used treatments for autism, but the research on their use for treating autism has been limited. Method This study is a randomized, double-blind, placebo-controlled three month vitamin/mineral treatment study. The study involved 141 children and adults with autism, and pre and post symptoms of autism were assessed. None of the participants had taken a vitamin/mineral supplement in the two months prior to the start of the study. For a subset of the participants (53 children ages 5-16 pre and post measurements of nutritional and metabolic status were also conducted. Results The vitamin/mineral supplement was generally well-tolerated, and individually titrated to optimum benefit. Levels of many vitamins, minerals, and biomarkers improved/increased showing good compliance and absorption. Statistically significant improvements in metabolic status were many including: total sulfate (+17%, p = 0.001, S-adenosylmethionine (SAM; +6%, p = 0.003, reduced glutathione (+17%, p = 0.0008, ratio of oxidized glutathione to reduced glutathione (GSSG:GSH; -27%, p = 0.002, nitrotyrosine (-29%, p = 0.004, ATP (+25%, p = 0.000001, NADH (+28%, p = 0.0002, and NADPH (+30%, p = 0.001. Most of these metabolic biomarkers improved to normal or near-normal levels. The supplement group had significantly greater improvements than the placebo group on the Parental Global Impressions-Revised (PGI-R, Average Change, p = 0.008, and on the subscores for Hyperactivity (p = 0.003, Tantrumming (p = 0.009, Overall (p = 0.02, and Receptive Language (p = 0.03. For the other three assessment tools the difference between treatment group and placebo group was not statistically significant.

    Background We report the concentrations and distributions of urinary arsenic (As) metabolites in 233 residents exposed to 20, 90, or 160 μg/L inorganic arsenic (iAs) in drinking water from three villages in Hohhot, Inner Mongolia, China, that formed one control and two exposed groups. Methods We used hydride generation-atomic absorption spectrometry (HGAAS) to determine iAs, monomethylarsonic acid (MMA), and dimethylarsinic acid (DMA). Results The concentrations of each urinary As species in the two exposed groups were significantly higher than in the control group for both children and adults. Both children and adults in exposed groups had higher percent iAs and MMA and lower percent DMA, and low primary and secondary methylation indices (PMI and SMI, respectively) than those in the control group. However, children showed significant increases in percent DMA and the SMI as well as decreases in the percent MMA when the iAs exposure level increased from 90 to 160 μg/L. In addition, children in the two exposed groups showed lower percent MMA but higher percent DMA and higher SMI than adults in the same exposed group. No significant differences in As metabolite concentrations and distributions were found between males and females in each group. A significant correlation was also found in the SMI between 11 pairs of children and their mothers from the 160-μg/L–exposed group. Conclusions Children had higher a capacity for secondary methylation of As than adults when exposed to the same concentrations of iAs in drinking water. Exposure to As may increase the capacity for methylation in children to some extent. PMID:17450238

    2010-12-01

    Cardiovascular disease is predicted to be a leading cause of death and disability worldwide for the foreseeable future. Observational studies link a variety of prevalent early life experiences (for example, smoking in pregnancy, child poverty) to increased risk of adult cardiovascular disease. Experimental animal studies suggest plausible causal relationships. However, there has been little consideration of how to use this wealth of information to benefit children's futures. Policy documents have drawn on research evidence to recognise that early experience influences life chances, the development of human capital, and long-term health. This has led to a general policy emphasis on prevention and early intervention. To date, there are few examples of the evidence base being useful in shaping specific policies, despite potential to do so, and some examples of policy misunderstanding of science. Minor changes to the perspectives of epidemiological research in this area might greatly increase the potential for evidence-based policy. PMID:21413485

    1990-01-01

    Recent investigations of Adult Children of Alcoholics (ACOAs) have focused on identifying factors associated with psychological resilience and their role in academic achievement. The present study hypothesized that rather than being associated with psychological resilience, academic achievement more likely would be associated with decreased psychological functioning or emotional distance due to the single-minded pursuit of one particular endeavor. Gender differences in types of problems reported by ACOAs were also hypothesized. In a sample of 419 college students, ACOAs reported more problems than non-ACOAs in areas of interpersonal anxiety, depression, and family problems but not academic skills. There were few gender effects. Results were discussed in terms of the psychological resilience hypothesis.

    Fields, David A; Goran, Michael I; McCrory, Megan A

    2002-03-01

    Laboratory-based body-composition techniques include hydrostatic weighing (HW), dual-energy X-ray absorptiometry (DXA), measurement of total body water (TBW) by isotope dilution, measurement of total body potassium, and multicompartment models. Although these reference methods are used routinely, each has inherent practical limitations. Whole-body air-displacement plethysmography is a new practical alternative to these more traditional body-composition methods. We reviewed the principal findings from studies published between December 1995 and August 2001 that compared the BOD POD method (Life Measurement, Inc, Concord, CA) with reference methods and summarized factors contributing to the different study findings. The average of the study means indicates that the BOD POD and HW agree within 1% body fat (BF) for adults and children, whereas the BOD POD and DXA agree within 1% BF for adults and 2% BF for children. Few studies have compared the BOD POD with multicompartment models; those that have suggest a similar average underestimation of approximate 2-3% BF by both the BOD POD and HW. Individual variations between 2-compartment models compared with DXA and 4 -compartment models are partly attributable to deviations from the assumed chemical composition of the body. Wide variations among study means, -4.0% to 1.9% BF for BOD POD - HW and -3.0% to 1.7% BF for BOD POD - DXA, are likely due in part to differences in laboratory equipment, study design, and subject characteristics and in some cases to failure to follow the manufacturer's recommended protocol. Wide intersubject variations between methods are partly attributed to technical precision and biological error but to a large extent remain unexplained. On the basis of this review, future research goals are suggested.

    Full Text Available Abstract Background In the absence of current cumulative dietary exposure assessments, this analysis was conducted to estimate exposure to multiple dietary contaminants for children, who are more vulnerable to toxic exposure than adults. Methods We estimated exposure to multiple food contaminants based on dietary data from preschool-age children (2–4 years, n=207, school-age children (5–7 years, n=157, parents of young children (n=446, and older adults (n=149. We compared exposure estimates for eleven toxic compounds (acrylamide, arsenic, lead, mercury, chlorpyrifos, permethrin, endosulfan, dieldrin, chlordane, DDE, and dioxin based on self-reported food frequency data by age group. To determine if cancer and non-cancer benchmark levels were exceeded, chemical levels in food were derived from publicly available databases including the Total Diet Study. Results Cancer benchmark levels were exceeded by all children (100% for arsenic, dieldrin, DDE, and dioxins. Non-cancer benchmarks were exceeded by >95% of preschool-age children for acrylamide and by 10% of preschool-age children for mercury. Preschool-age children had significantly higher estimated intakes of 6 of 11 compounds compared to school-age children (p Conclusions Dietary strategies to reduce exposure to toxic compounds for which cancer and non-cancer benchmarks are exceeded by children vary by compound. These strategies include consuming organically produced dairy and selected fruits and vegetables to reduce pesticide intake, consuming less animal foods (meat, dairy, and fish to reduce intake of persistent organic pollutants and metals, and consuming lower quantities of chips, cereal, crackers, and other processed carbohydrate foods to reduce acrylamide intake.

    Both off-line and on-line comprehension studies suggest not only toddlers and preschoolers, but also older school-age children have trouble interpreting contrast-marking pitch prominence. To test whether children achieve adult-like proficiency in processing contrast-marking prosody during school years, an eye-tracking experiment examined the effect of accent on referential resolution in six- to eleven-year-old children and adults. In all age groups, a prominent accent facilitated the detection of a target in contrastive discourse sequences (pink cat → green cat), whereas it led to a garden path in non-contrastive sequences (pink rabbit → green monkey: the initial fixations were on rabbits). While the data indicate that children as young as age six immediately interpret contrastive accent, even the oldest child group showed delayed fixations compared to adults. We argue that the children's slower recovery from the garden path reflects the gradual development in cognitive flexibility that matures independently of general oculomotor control. PMID:23253142

    Full Text Available Past work has shown relationship between the ability to discriminate spectral patterns and measures of speech intelligibility. The purpose of this study was to investigate the ability of both children and young adults to discriminate static and dynamic spectral patterns, comparing performance between the two groups and evaluating within- group results in terms of relationship to speech-in-noise perception. Data were collected from normal-hearing children (age range: 5.4-12.8 years and young adults (mean age: 22.8 years on two spectral discrimination tasks and speech-in-noise perception. The first discrimination task, involving static spectral profiles, measured the ability to detect a change in the phase of a low-density sinusoidal spectral ripple of wideband noise. Using dynamic spectral patterns, the second task determined the signal-to-noise ratio needed to discriminate the temporal pattern of frequency fluctuation imposed by stochastic lowrate frequency modulation (FM. Children performed significantly poorer than young adults on both discrimination tasks. For children, a significant correlation between speech-in-noise perception and spectral- pattern discrimination was obtained only with the dynamic patterns of the FM condition, with partial correlation suggesting that factors related to the children’s age mediated the relationship.

    The use of antibiotics, proton pump inhibitor (PPI), and histamine 2 receptor blocker (H2B) was compared between children and adults in the community from 2005 through 2011. Antibiotic prescription rates remained stable for children, but increased significantly for adults, P = .03. PPI prescription rates increased for children, P = .02 and for adults, P = .009. H2B prescription rates increased for children, P = .03, but not for adults. Antibiotic prescription rates were significantly higher in children than adults in all 7 years, P < .0001. In contrast, PPI prescription rates were significantly higher in adults than children in all 7 years, P < .0001. H2B prescription rates were significantly higher in adults than children 1 to 18 years old P < .0001; however, H2B prescription rates were highest in children <1 year old, P = .0001. The high use of oral antibiotics, PPI, and H2B among outpatients may be a contributing factor to the rise of Clostridium difficile infection in the community. PMID:26350427

  12. Radiation-induced thyroid cancer in children and adult population, living in contaminated territories after the Chernobyl accident

    International Nuclear Information System (INIS)

    Results of the analysis of own and literature data on the occurrence and development of radiation-induced thyroid cancer are presented. Analysis involved distribution of the thyroid cancer incidence among 1 million children and 3 millions adults, living in the radioactively contaminated territories of Russia by age and sex. The main attention was paid to the understanding of latency period of spontaneous and radiation-induced cancer, comparison of oncological pathology features in children and adults, and the role of screening in the increase of incidence rate parameters. Analysis permitted to offer new interpretation of several previously known facts and to make new statements on the induction and development of radiogenic thyroid cancer, in particularly, on far more significant increase of the thyroid cancer incidence in adults, living in the contaminated territories, than it was considered earlier

  13. From algorithmic computing to direct retrieval: evidence from number and alphabetic arithmetic in children and adults.

    1998-03-01

    A number of theories of mental arithmetic suggest that the ability to solve simple addition and subtraction problems develops from an algorithmic strategy toward a strategy based on the direct retrieval of the result from memory. In the experiment presented here, 2nd and 12th graders were asked to solve two tasks of number and alphabet arithmetic. The subjects transformed series of 1 to 4 numbers or letters (item span) by adding or subtracting an operand varying from 1 to 4 (operation span). Although both the item and operation span were associated with major and identical effects in the case of both numbers and letters at 2nd grade, such effects were clearly observable only in the case of letters for the adult subjects. This suggests the use of an algorithmic strategy for both types of material in the case of the children and for the letters only in the case of the adults, who retrieved numerical results directly from memory.

    Epidemiologic and experimental research on the potential carcinogenic effects of extremely low frequency electromagnetic fields (EMF) has now been conducted for over two decades. Cancer epidemiology studies in relation to EMF have focused primarily on brain cancer and leukemia, both from residential sources of exposure in children and adults and from occupational exposure in adult men. Because genotoxic effects of EMF have not been shown, most recent laboratory research has attempted to show biological effects that could be related to cancer promotion. In this report, we briefly review residential and occupational EMF studies on brain cancer. We also provide a general review of experimental studies as they relate both to the biological plausibility of an EMF-brain cancer relation and to the insufficiency of such research to help guide exposure assessment in epidemiologic studies. We conclude from our review that no recent research, either epidemiologic or experimental, has emerged to provide reasonable support for a causal role of EMF on brain cancer. PMID:11550314

  15. Assessing dehydroepiandrosterone in saliva: a simple radioimmunoassay for use in studies of children, adolescents and adults

    International Nuclear Information System (INIS)

    While salivary assays for some hormones are widely used, the availability of assays for salivary DHEA is limited. By adapting a commercially available radioimmunoassay serum kit, we developed a reliable, efficient and sensitive measure of DHEA in saliva that does not require separation or extraction. The minimum detection limit was 4.0 pg/ml. Intra-assay coefficients of variation (CV%) were on average 4.05, and inter-assay CVs averaged 9.70. Method accuracy, determined by spike recovery, and linearity, determined by serial dilution, averaged 99.55 and 92.03%. Levels in matched serum and saliva samples showed strong linear relationships for adult males and females. Specific guidelines are developed for sample collection, storage, and preparation procedures. Reference ranges for salivary DHEA levels are provided for 64 children ages 8-11, 96 adolescents ages 12-17 and 48 adults ages 30-45. Salivary DHEA levels are shown to reflect developmental, gender and diurnal differences. (Copyright (c) 1999 Elsevier Science B.V., Amsterdam. All rights reserved.)

    Collagenous gastritis is a rare condition characterized by surface epithelial damage, subepithelial collagen deposition, and a lamina propria inflammatory infiltrate. Previous studies have proposed 2 clinicopathologic subtypes: (1) children (18 y of age or younger) presenting with severe anemia, nodular gastric mucosa, and isolated gastric disease; and (2) adults with chronic watery diarrhea that is associated with diffuse collagenous involvement of the gastrointestinal tract. However, notable exceptions exist. In fact, broad variability in clinical presentation, etiology, treatment and disease course has been reported. To better define the clinicopathologic features of collagenous gastritis, we have collected 10 pediatric and 21 adult cases and describe their clinical, endoscopic, pathologic, and follow-up findings. Both children and adults presented with similar clinical symptoms such as anemia (50%, 35%, respectively), epigastric/abdominal pain (50%, 45%), and diarrhea (40%, 55%). Concomitant immune disorders were identified in 2 (20%) children and 3 (14%) adults. Further, 7 of 17 (41%) adults were taking medications associated with other immune-related gastrointestinal diseases including olmesartan and antidepressants. Histologically, there were no differences between children and adults with collagenous gastritis in the location of gastric involvement, mean collagenous layer thickness, and prominence of eosinophils (P>0.05). Extragastric collagenous involvement was also seen with comparable frequencies in each cohort (44%, 59%). Follow-up information was available for 22 of 31 (71%) patients and ranged from 2 to 122 months (mean, 33.6 mo). Despite medical management in most cases, persistence of symptoms or collagenous gastritis on subsequent biopsies was seen in 100% of children and 82% of adults. Of note, treatment for 1 adult patient involved cessation of olmesartan resulting in resolution of both symptoms and subepithelial collagen deposition on subsequent

  17. Application of Jean Piaget's theory of human development for nursing children in an adult intensive therapy unit.

    Piaget (1964) believed that interaction with the environment has a large part to play in human development. Matthew (1986) states that in an ideal world critically ill children should be cared for by staff trained in paediatrics, within designated paediatric intensive therapy units. Unfortunately, there are only 28 paediatric intensive therapy units in Great Britain (CMA Medical Data, 1987), consequently each year a third of children requiring intensive care are admitted to adult intensive therapy units (ITU). A knowledge and understanding of developmental psychology can therefore be beneficial to nurses in assessing which stage of development a child has reached, in order to plan the correct level of stimulation, and hence facilitate progress rather than regression in the accomplishment of developmental tasks. The psychological and social processes involved in Jean Piaget's (1896-1980) theory of human development are discussed with regard to nursing children requiring intubation and ventilation in an adult ITU.

    OBJECTIVE: The aim of the study was to describe third-party disability experienced by adult-children as a result of hearing impairment (HI) in a parent. DESIGN: Using semi-structured interviews, participants were asked to describe the impact of a parent's HI on their relationship and communication......, and providing support to the parent with HI. The described feelings included frustration, uncertainty, and loss surrounding their communication and relationship with their parent with HI. These feelings arose as a result of implementing coping strategies, plus these feelings drove the employment of coping...... strategies. CONCLUSIONS: Adult-children of parents with HI experience third-party disability, however, the participation restrictions and activity limitations experienced by children appear less than experienced by spouses....

    Serum levels of insulin-like growth factor-I (IGF-I) increase with age and pubertal development. The large variation in circulating IGF-I levels in adolescence makes it difficult to use the IGF-I value of a single child in the assessment of his growth status. In addition, the interference of IGF......-binding proteins in many IGF-I assays contributes to this problem. We measured IGF-I in acid-ethanol-extracted serum from 1030 healthy children, adolescents, and adults, employing a RIA that reduces interference of IGF-binding proteins by using monoiodinated Tyr31-[125I]des-(1-3)IGF-I as radioligand. Mean serum...... children in a cross-sectional design. Thus, the age-, sex-, and puberty-corrected IGF-I values may, in fact, improve the use of serum IGF-I as a diagnostic tool to distinguish between a child with retarded puberty and a GH-deficient individual....

    Trypanosoma brucei gambiense sleeping sickness follows a long asymptomatic phase and persists in ancient foci from which epidemic clinical disease arises. A putative focus of T. b. gambiense infections has been identified, initially in mothers and young children, on the Lake Albert shoreline of Western Uganda leading to mass screening of 6207 individuals in September 2008. T. b. gambiense infections were identified by Card Agglutination Test for Trypanosomiasis (CATT) and sub-species-specific PCR although parasitological methods failed to confirm any patent trypanosome infections. In April 2009, CATT positives were re-visited; diagnosis of individuals by CATT and PCR was unstable over the two time points and parasites remained undetected, even using mini Anion Exchange Centrifugation Technique (mAECT). These observations suggest the possibility of a silent focus of disease, where all infected individuals are in a latent stage, and highlight our limited understanding of the local natural history and disease progression of T. b. gambiense in children and adults.

    According to psychological models as well as common intuition, intense positive and negative situations evoke highly distinct emotional expressions. Nevertheless, recent work has shown that when judging isolated faces, the affective valence of winning and losing professional tennis players is hard to differentiate. However, expressions produced by professional athletes during publicly broadcasted sports events may be strategically controlled. To shed light on this matter we examined if ordinary people's spontaneous facial expressions evoked during highly intense situations are diagnostic for the situational valence. In Experiment 1 we compared reactions with highly intense positive situations (surprise soldier reunions) versus highly intense negative situations (terror attacks). In Experiment 2, we turned to children and compared facial reactions with highly positive situations (e.g., a child receiving a surprise trip to Disneyland) versus highly negative situations (e.g., a child discovering her parents ate up all her Halloween candy). The results demonstrate that facial expressions of both adults and children are often not diagnostic for the valence of the situation. These findings demonstrate the ambiguity of extreme facial expressions and highlight the importance of context in everyday emotion perception. (PsycINFO Database Record

    The aim of this study was to focus on similarities in the discrimination of three different quantities--time, number, and line length--using a bisection task involving children aged 5 and 8 years and adults, when number and length were presented nonsequentially (Experiment 1) and sequentially (Experiment 2). In the nonsequential condition, for all age groups, although to a greater extent in the younger children, the psychophysical functions were flatter, and the Weber ratio higher for time than for number and length. Number and length yielded similar psychophysical functions. Thus, sensitivity to time was lower than that to the other quantities, whether continuous or not. However, when number and length were presented sequentially (Experiment 2), the differences in discrimination performance between time, number, and length disappeared. Furthermore, the Weber ratio values as well as the bisection points for all quantities presented sequentially appeared to be close to that found for duration in the nonsequential condition. The results are discussed within the framework of recent theories suggesting a common mechanism for all analogical quantities. PMID:19031154

    Full Text Available Introduction. Sport presents a risk of ocular trauma and accounts for a significant number of eye injuries that require hospital admission. The sport of golf presents a risk to eyesight from fast moving objects such as golf clubs and balls. This study aims to investigate the associations of golf with eye injuries and the reasons that these injuries occur. Material/Methods. A literature search was conducted using the databases MEDLINE, Web of Science, SPORTDiscus, and PsycINFO. Grey literature was searched using the WHO international clinical trials registry platform, Google Scholar, and ProQuest. Data was extracted using a standardised form and summarised into a report. Results and Discussion. Twenty-three studies were found relating to eye injuries in golf. Injuries appear to be rare, but more frequent in men and children. Injuries resulted in high rates of enucleation and visual impairment. Children sustained more injury from golf clubs whereas adults sustained more injuries from golf balls. Conclusion. Efforts are needed to encourage golf participants to understand the risks of ocular and indeed other head injuries. Initiatives to provide appropriate supervision and education on this topic are merited. Further research is needed to investigate the circumstances of eye injury in golf and assess the effects of interventions aimed at reducing risk of injury.

    Hepatitis A is a widespread infectious disease. The prevalence of the disease is closely related to socioeconomic status (SES) and environmental factors. Understanding its prevalence is essential for instituting appropriate precautions. The aim of this study was to determine the prevalence of hepatitis A and evaluate the associated demographic features in children and young adults in Istanbul. In total, 630 individuals between the ages of 5-24 were included in the study. They were classified into four age groups (5-9, 10-14, 15-19 and 20-24 years). The seropositivity of hepatitis A in the whole study population was 40%. Age-specific prevalence was 11.4% in children 5-9 years old, 29% in those 10-14 years old, 49.7% in those 15-19 years old and 69% in those 20-25 years old. Seropositivity was associated with increasing age, low SES, large family size, low maternal educational level, use of unsafe drinking water and living in regions with poor infrastructure and incomplete urbanization. When we compared our results with previous seroprevalence studies performed in Istanbul, we found an epidemiological shift towards increasing age. Factors associated with changes in prevalence were urbanization and associated infrastructure improvement, knowledge of the disease by the population, use of good hygiene and use of vaccination in those at high risk.

    Full Text Available Abstract Background As patients with juvenile idiopathic arthritis (JIA progress into adulthood, long-term outcome is determined by disease activity, physical and psychosocial development. Decreased aerobic capacity may play a critical role in health-related outcomes in JIA, since it has been linked with cardiovascular morbidity and mortality in late adulthood. The objectives of the current study are to examine the aerobic capacity and its relation to parameters of disease activity in children, adolescents and young adults with JIA. Methods Sixty-three patients with JIA (aged 10–27 years were cross sectional studied regarding their aerobic capacity and correlations were made to demographic, disease-related variables, and medication utilization. in a cross-sectional study group of 63 patients of all subtypes. Patients were divided in three age groups, 10–13 years; 14–17 years and 18–27 years. Results Reduced aerobic capacity is found in clinical remission as well as active disease in all subtypes and all age groups. Aerobic capacity is more impaired in active disease shown by DAS 28, JADAS 27, ESR and serum thrombocyte counts. Lower haemoglobin has a negative impact. Long-term used medication including methotrexate and corticosteroids didn’t influence outcome. There is no association with current sports participation. Conclusion Reduced aerobic capacity is present in children and adolescents with JIA, both in active disease and in patients with remission. Measures of aerobic capacity may serve as important outcome measure in JIA.

    Acral pseudolymphomatous angiokeratoma of children (APACHE) is a condition that was first described in 1990 in a group of children, but has since been described in adults. We present the cases of identical twin patients aged 40 years. The first brother presented with an 8-year history of itchy lesions over the left ankle and the insteps of both feet. After a diagnostic biopsy, he was treated with potent steroids under occlusion for 8 weeks, which resulted in flattening of the lesions and resolution of the pruritus. The second twin had a 20-year history of a very similar presentation but the lesions were less pronounced; he chose not to have treatment. No other family members were affected. Skin biopsies from both patients showed similar changes. Within an overall hyperkeratotic and acanthotic epidermis, there were focal areas of lichenoid change and epidermal thinning. Beneath these areas, there was oedema and nodular aggregates of dense inflammatory cell infiltrate, predominantly lymphocytic infiltrate. APACHE has not been previously described in twins.

    Background Asthenopic symptoms associated with convergence insufficiency (CI) may compromise a person's ability to work or study. We investigated the effectiveness of orthoptic exercises in relieving symptoms related to CI and long-time results in adults and children. Methods The data were retrospectively gathered from the patient clinical files. A total of 135 patients met the inclusion criteria of suffering asthenopic symptoms and CI but had not received prior strabismus surgery or orthoptic exercises. Results The mean age was 26 ± 17 years, 74% of them were female. The patients (N = 135) suffered from CI and had at least one of the following symptoms: eyestrain, blurring of vision, problems in reading and while doing work-up at close distance or headache. In the two-year follow-up time, 4% of the patients needed to be retreated and 3% of the patients required strabismus surgery. There were no significant differences between adults and children in near point of convergence (NPC), number of visits needed or fusional vergence at the end of treatment nor did the outcome depend on the number of visits. 59.5% of children vs. 51.9% of adults were free of symptoms when completing the exercises. Conclusions In conclusion orthoptic exercises are effective in relieving asthenopic symptoms in adults and children. The effects of orthoptic exercises on NPC and fusional vergence were equal in adults and in children and not dependent on the number of visits needed for successful outcome. With orthoptic exercises it is possible to achieve longstanding relief on the symptoms of CI.

    Background The immunological differences between children and adults with AIDS in China are not well documented.Th1/Th2 cytokines and chemokines are two types of immune factors intimately involved in disease progression of HIV-1 infection. This study aimed to identify changes in plasma levels of Th1/Th2 cytokines inerleukin (IL)-18, IL-16, IL-10 and chemokines regulated on activation, normal T cell expressed and secreted (RANTES), stromal cell-derived factor-1 (SDF-1) and monocyte chemoattractant protein-1 (MCP-1) in HIV-1-infected children and adults in China.Methods Seventy-five children with AIDS and 35 adult AIDS patients were recruited and clinical data were collected.CD4+ T lymphocyte counts were measured by flow cytometery and plasma HIV RNA levels were measured by quantitative RT-PCR. Plasma levels of IL-18, IL-10, IL-16, RANTES, MCP-1, SDF-1α and SDF-1β were quantified by enzyme-linked immunosorbent assay. The levels of β2-microglobulin (β2-MG) and soluble Fas (sFas) were measured to validate the level of humoral and cellular immune activation.Results The mean levels of all cytokines in pediatric and adult AIDS patients were significantly higher than in their healthy controls (P <0.01). The mean levels of these cytokines were higher in pediatric patients than in adult patients (P <0.05, except for SDF-1α and β2-MG). Some of the cytokine levels in patients younger than 6 years old was higher than in older children and adults with AIDS (IL-10, IL-18, SDF-1α, MCP, RANTES and sFas, P<0.05). Levels of IL-18, IL-10,RANTES and β2-MG of pediatric patients increased as the levels of viral load increased (P <0.05).Conclusions Abnormal immune activation can be measured in Chinese pediatric and adult patients with AIDS, and is higher in children than in adult patients. The cytokines levels coincide with disease progression of AIDS, but have no direct relationship with total CD4+ T cell count.

    Iodine-131 in urine samples from 15 Japanese subjects was determined during the period 4 to 29 May 1986. In a male adult, the peak concentration (3.3 Bq dm-3) was observed on 9 May, the levels decreasing thereafter to less than the detection limit by 29 May, The highest concentrations observed was 7.6 Bq dm-3 in a female adult. The urinary concentrations in the 11 adult subjects appeared to correlate with consumption of green leafy vegetables and milk. In four children, 6 to 14 years old, 131I concentrations in urine were generally higher than those of the adults. The major source of 131I intake was confirmed to be from vegetables, not milk.

    Full Text Available Background and Aim: Since knowing the mechanisms which evoke non-fluency is the first step in the treatment of stuttering, and there are very few researches in Persian which consider the role of the linguistic factors behind stuttering, this study is an attempt to provide answers to some of numerous questions about stuttering by comparing the stuttered words` type in stuttered children and adults. Materials and Methods: In this study stuttered people were divided into 5 age groups as follows: 3-6, 7-9, 10-12, 13-16, and older than 17 years old. Each group had ten participants. Forty-two of the 50 participants were male, and the youngest person was 3 years old and the eldest one was 32 years old. The study method involved recording at least 5 minuets of spontaneous speech of every one who was diagnosed of suffering from stuttering by two speech and language pathologists. The percent of non-fluency on every word's type was determined where a content word was followed or preceded by a function word (Function-Function-Content words and Function-Content words contexts. Then these findings were analyzed by Kruskal-Wallis and Mann-Whitney tests. Results: The results of this study show while function words are dominantly more stuttered than content words in children less than 13 years old in Function-Function-Content words context, we consider more disfluency on content words and second function word by getting old. We consider more stuttering on function words in children less that 13 years old in Function-Content words context too and increased non-fluency on content word by growing up. Results also show meaningful differences between the fifth group and others in the amount of stuttering on second function word in the Function-Function-Content words contexts and also between the first group and the others in amount of non-fluency both on function and content words in Function-Content words context. Conclusion: People who stutter from Farsi speakers

  14. Mental models or methodological artefacts? Adults' 'naïve' responses to a test of children's conceptions of the earth.

    Vosniadou and Brewer (1992) claim that children's drawings and answers to questions show that they have naive, theory-like 'mental models' of the earth; for example, they believe it to be flat, or hollow with people inside. However, recent studies that have used different methods have found little or no evidence of these misconceptions. The contrasting accounts, and possible reasons for the inconsistent findings, were tested by giving adults (N = 484) either the original task (designed for 5-year olds) or a new version in which the same drawing instructions and questions were rephrased and clarified. Many adults' responses to the original version were identical to children's 'naïve' drawings and answers. The new version elicited substantially fewer non-scientific responses. These findings indicate that even adults find the original instructions and questions ambiguous and confusing, and that this is the principal reason for their non-scientific drawings and answers. Since children must find the task even more confusing than adults, this explanation very probably applies to many of their non-scientific responses, too, and therefore accounts for the discrepant findings of previous research. 'Naïve' responses result largely from misinterpretation of Vosniadou and Brewer's apparently simple task, rather than from mental models of the earth.

  15. Feeling present in arousing virtual reality worlds: prefrontal brain regions differentially orchestrate presence experience in adults and children

    Directory of Open Access Journals (Sweden)

    2008-08-01

    Full Text Available Virtual reality (VR is a powerful tool for simulating aspects of the real world. The success of VR is thought to depend on its ability to evoke a sense of "being there", that is, the feeling of "Presence". In view of the rapid progress in the development of increasingly more sophisticated virtual environments (VE, the importance of understanding the neural underpinnings of presence is growing. To date however, the neural correlates of this phenomenon have received very scant attention. An fMRI-based study with 52 adults and 25 children was therefore conducted using a highly immersive VE. The experience of presence in adult subjects was found to be modulated by two major strategies involving two homologous prefrontal brain structures. Whereas the right DLPFC controlled the sense of presence by down-regulating the activation in the egocentric dorsal visual processing stream, the left DLPFC up-regulated widespread areas of the medial prefrontal cortex known to be involved in self-reflective and stimulus-independent thoughts. In contrast, there was no evidence of these two strategies in children. In fact, anatomical analyses showed that these two prefrontal areas have not yet reached full maturity in children. Taken together, this study presents the first findings that show activation of a highly specific neural network orchestrating the experience of presence in adult subjects, and that the absence of activity in this neural network might contribute to the generally increased susceptibility of children for the experience of presence in VEs.

  16. Validation of adult height prediction based on automated bone age determination in the Paris Longitudinal Study of healthy children

    International Nuclear Information System (INIS)

    An adult height prediction model based on automated determination of bone age was developed and validated in two studies from Zurich, Switzerland. Varied living conditions and genetic backgrounds might make the model less accurate. To validate the adult height prediction model on children from another geographical location. We included 51 boys and 58 girls from the Paris Longitudinal Study of children born 1953 to 1958. Radiographs were obtained once or twice a year in these children from birth to age 18. Bone age was determined using the BoneXpert method. Radiographs in children with bone age greater than 6 years were considered, in total 1,124 images. The root mean square deviation between the predicted and the observed adult height was 2.8 cm for boys in the bone age range 6-15 years and 3.1 cm for girls in the bone age range 6-13 years. The bias (the average signed difference) was zero, except for girls below bone age 12, where the predictions were 0.8 cm too low. The accuracy of the BoneXpert method in terms of root mean square error was as predicted by the model, i.e. in line with what was observed in the Zurich studies. (orig.)

    AIM: To assess the role of lactase non-persistence/persistence in school-aged children and their milk-related sYmptoms.METHODS: The genotypes for the C/T-13910 variant associated with lactase non-persistence/ persistence were determined using PCR-minisequencing in a group of 172 children with a mean age of 8.6 years (SE = 0.02,93 boys) participating in a follow-up study for cow's milk allergy. The parents were asked to assess their children's milk consumption and abdominal symptoms.RESULTS: The presence of allergy to cow's milk was not associated with the C/G13910 genotype related with a decline of lactase enzyme activity during childhood (lactase non-persistence). The frequency of the C/G13910genotype (16%) was similar to published figures for the prevalence of adult-type hypolactasia in Finland. The majority of the children (90%) in this series consumed milk but 26% of their families suspected that their children had milk-related symptoms. Forty-eight percent of the children with the C/G13910 genotype did not drink milk at all or consumed a low lactose containing diet prior to the genotyping (P<0.004 when compared to the other genotypes).CONCLUSION: Analysis of the C/T-13910 polymorphism is an easy and reliable method for excluding adult-type hypolactasia in children with milk-related symptoms.Genotyping for this variant can be used to advise diets for children with a previous history of cow's milk allergy.

    This study describes the effects of the introduction of universal infant pneumococcal conjugate vaccination in 2006 on invasive pneumococcal disease (IPD) among children and adults in Germany with a focus on the dynamics of serotype distribution in vaccinated and non-vaccinated age groups. Over a period of 22 years (1992-2014), microbiological diagnostic laboratories from all over Germany have been sending isolates of IPD cases to the German National Reference Center for Streptococci on a voluntary basis. Streptococcus pneumoniae isolates were serotyped using Neufeld's Quellung method. Among children vaccination (1997-2006) to 23.5% in the early vaccination period (2007-2010; p = 1.30E-72) and sank further to 5.2% in the late vaccination period (2010-2014; p = 4.59E-25). Similar reductions were seen for the separate age groups vaccination period (1992-2006) to 24.7% (p = 3.78E-88) in the early vaccination period and 8.2% (p = 5.97E-161) in the late vaccination period. Both among children and among adults, the non-PCV7 serotypes 1, 3, 7F and 19A significantly increased in the early vaccination period. After the switch from PCV7 to PVC10/PCV13 for infant vaccination in 2010, serotypes 1, 6A and 7F significantly decreased. A decrease in serotype 19A was only observed in 2013-2014, as compared to 2010-2011 (children p = 4.16E-04, adults p = 6.98E-06). Among adults, serotype 3, which strongly increased in the early vaccination period (p = 4.44E-15), remained at a constant proportion in the late vaccination period. The proportion of non-PCV13 vaccine serotypes increased over the whole vaccination period, with serotypes 10A, 12F, 23B, 24F and 38 most significantly increasing among children and serotypes 6C, 12F, 15A, 22F and 23B increasing among adults. Eight years of childhood pneumococcal conjugate vaccination have had a strong effect on the pneumococcal population in Germany, both among the target group for vaccination as well as among older children and adults.

    Full Text Available Aim: To determine combinations of blood glucose tests: oral glucose tolerance (OGT, fasting plasma glucose (FBG and hemoglobin A1C (HbA1C that are associated with highest diagnostic rates of prediabetes in non-diabetic American children and adults.Methods: The 2007-2008 U.S. National Health and Nutrition Examination Surveys data were used for this study. Overall and specific prevalence of prediabetes (defined using OGT+FPG, OGT+HbA1C, HbA1C+FPG and OGT+FPG+HbA1C tests were determined across age, race/ethnicity, sex and BMI categories.Results: FPG+HbA1C test was associated with significantly higher diagnostic rates of prediabetes across age, race/ethnicity and BMI. Estimates of overall prevalence of prediabetes using OGT+FPG, OGT+HbA1C, HbA1C+FPG and OGT+FPG+HbA1C tests were 20.3%, 24.2%, 33% and 34.3%, respectively. Compared to OGT+FPG, the use of HbA1C+FPG test in screening was associated with 44.8%, 135%, 38.6% and 35.9% increased prevalence of prediabetes in non-Hispanic White, non-Hispanic Black, Mexican-American and other racial/ethnic men, respectively. The corresponding values in women were 67.8%, 140%, 37.2% and 42.6%, respectively. Combined use of all blood glucose tests did not improve the overall and gender-specific prediabetes prevalence beyond what was observed using HbA1C+FPG test.Conclusions: HbA1C criteria were associated with higher diagnosis rates of prediabetes than FPG and OGT tests in non-diabetic American children and adults. Using a combination of HbA1C and FPG test in screening for prediabetes reduces intrinsic systematic bias in using just HbA1C testing and offers the benefits of each test. A well-defined HbA1C that takes into consideration race/ethnicity, gender, age and body mass index may improve detection of prediabetes in population and clinical settings.

    Full Text Available Abstract Background As patients with juvenile idiopathic arthritis (JIA progress into adulthood, long-term outcome is determined by disease activity, physical and psychosocial development. Decreased aerobic capacity may play a critical role in health-related outcomes in JIA, since it has been linked with cardiovascular morbidity and mortality in late adulthood. The objectives of the current study are to examine the aerobic capacity and its relation to parameters of disease activity in children, adolescents and young adults with JIA. Methods Sixty-three patients with JIA (aged 10–27 years were cross sectional studied regarding their aerobic capacity and correlations were made to demographic, disease-related variables, and medication utilization. in a cross-sectional study group of 63 patients of all subtypes. Patients were divided in three age groups, 10–13 years; 14–17 years and 18–27 years. Results Reduced aerobic capacity is found in clinical remission as well as active disease in all subtypes and all age groups. Aerobic capacity is more impaired in active disease shown by DAS 28, JADAS 27, ESR and serum thrombocyte counts. Lower haemoglobin has a negative impact. Long-term used medication including methotrexate and corticosteroids didn’t influence outcome. There is no association with current sports participation. Conclusion Reduced aerobic capacity is present in adolescents and young adults with JIA, both in active disease and in patients with remission. Measures of aerobic capacity may serve as important outcome measure in JIA.

    Millions of children in Sub-Saharan Africa live with adults, often parents, who are HIV-infected or ill due to AIDS. These children experience social, emotional, and health vulnerabilities that overlap with, but are not necessarily the same as, those of orphans or other vulnerable children. Despite their distinctive vulnerabilities, research aimed at understanding the situation of these children has been limited until very recently. This review summarizes the state of knowledge based on a systematic search of PubMed and Web of Science that identified 47 empirical research articles that examined either the population prevalence of children living with HIV-infected or AIDS-sick adults, or the consequences of adult HIV infection or AIDS illness for child well-being. This review confirms that this population of children is substantial in size, and that the vulnerabilities they experience are multi-faceted, spanning physical and emotional health and schooling. Mechanisms were examined empirically in only a small number of studies, but encompass poverty, transmission of opportunistic infections, care for unwell adults, adult distress, AIDS stigma, lack of social support, maternal breastfeeding issues, and vertical HIV transmission. Some evidence is provided that infants, adolescents, children with infected or ill mothers, and children living with severely ill adults are particularly vulnerable. Future research would benefit from more attention to causal inference and further characterization of processes and circumstances related to vulnerability and resilience. It would also benefit from further study of variation in observed associations between adult HIV/AIDS and child well-being based on characteristics such as age, sex, kinship, severity of illness, TB co-infection, disclosure, and serostatus awareness. Almost one-quarter of the studies reviewed did not investigate variation based on any of these factors. More nuanced understanding of the short- and long

    Backpack palsy is a well-recognised, albeit rare, complication of carrying backpacks. Although it has been mostly described in cadets during strenuous training, sporadic cases of brachial nerve impairment have been reported in children and young adults. Here we reported the case of a 15-year-old girl who presented with a left-side brachial palsy with axonal denervation of C5C7 motor roots following a school challenge for the Duke of Edinburgh Award. Her symptoms began soon after starting the challenge and included weakness of shoulder abduction and elevation, as well as forearm, wrist and fingers extension. After 6 months of physiotherapy her motor function was completely restored. Backpack palsy can sometimes present in children and young adults. This disorder should be taken in consideration when planning for daily, as well as more challenging, physical activities in these age groups. PMID:27252125

    Full Text Available A clinical and laboratory evaluation of 11 children and young adults with measleslike rash was done during the measles outbreak in the Greater São Paulo Metropolitan area at the end of 1996 and spread over the country during 1997. Measles was laboratory confirmed in 07 patients by specific IgM detection in acute serum specimens using an IgM-capture EIA, by specific IgG seroconversion in serum pairs, and by reverse transcription PCR and virus isolation in peripheral blood lymphocytes. Clinical presentations were not always classic; one of the 07 cases had received measles vaccine and corresponded to modified clinical case of measles. The 4 remaining cases were negative for measles and were diagnosed as exanthem subitum (2 cases, scarlet fever and Kawasaki disease. The present study reinforces the view that clinical features alone are not sufficient for establishing an accurate diagnosis in the post-vaccine era, and a surveillance system based on sensitive laboratory results is needed so that it can confirm IgM-negative measles cases.

    Full Text Available Objectives. We have previously reported a high prevalence of gluten-related serological markers (GRSM in children and young adults with cerebral palsy (CP. The majority had no enteropathy to suggest coeliac disease (CD. Antibodies against transglutaminase 6 (anti-TG6 represent a new marker associated with gluten-related neurological dysfunction. The aim of this study was to investigate the prevalence of anti-TG6 antibodies in this group of individuals with an early neurological injury resulting in CP. Materials and Methods. Sera from 96 patients with CP and 36 controls were analysed for IgA/IgG class anti-TG6 by ELISA. Results. Anti-TG6 antibodies were found in 12/96 (13% of patients with CP compared to 2/36 (6% in controls. The tetraplegic subgroup of CP had a significantly higher prevalence of anti-TG6 antibodies 6/17 (35% compared to the other subgroups and controls. There was no correlation of anti-TG6 autoantibodies with seropositivity to food proteins including gliadin. Conclusions. An early brain insult and associated inflammation may predispose to future development of TG6 autoimmunity.

    Alkaptonuria (AKU) is caused by deficiency of the enzyme homogentisate 1,2 dioxygenase. It results in an accumulation of homogentisate which oxidizes spontaneously to benzoquinone acetate, a highly oxidant compound, which polymerises to a melanin-like structure, in a process called ochronosis. Asymptomatic during childhood, this accumulation will lead from the second decade of life to a progressive and severe spondylo-arthopathy, associated with multisystem involvement: osteoporosis/fractures, stones (renal, prostatic, gall bladder, salivary glands), ruptures of tendons/muscle/ligaments, renal failure and aortic valve disease. The pathophysiological mechanisms of AKU remain poorly understood, but recent advances lead us to reconsider the treatment strategy in AKU patients. Besides the supporting therapies (pain killers, anti-inflammatory drugs, physiotherapy, joints replacements and others), specific therapies have been considered (anti-oxidant, low protein diet, nitisinone), but clinical studies have failed to prove efficiency on the rheumatological lesions of the disease. Here we propose a treatment strategy for children and adults with AKU, based on a review of the latest findings on AKU and lessons from other aminoacipathies, especially tyrosinemias. PMID:25860819

    Full Text Available Background: Diarrheal diseases are a major cause of morbidity and mortality in resource-limited countries. Among the bacterial pathogens, diarrheagenic E. coli (DEC are most frequently implicated in cases of epidemic and endemic diarrhea worldwide. The objective of this study was to determine the prevalence of DEC in stool specimens from patients with acute diarrhea using polymerase chain reaction (PCR. Materials and Methods: Escherichia coli stool samples were collected from 115 hospitalized children and adults with acute diarrhea in Mangalore, a coastal city, in southern India. PCR amplification of eae, bfp, stx, ehx genes were used for detection of enteropathogenic (EPEC and shigatoxigenic E. coli (STEC, lt and st genes were used for enterotoxigenic E. coli (ETEC and astA gene for enteroaggregative E. coli (EAEC. Results: During the 24 month study period, of the 115 stool samples, DEC type was detected in 20 (17.4% using the PCR method. The most prevalent DEC was atypical EPEC accounting for 12 (10.4% cases followed by 4 cases of EAEC (3.4% and 4 of STEC (3.4%. No ETEC strains were isolated from any of the examined stool samples. Conclusion: This study suggests that the atypical EPEC are the newly emerging group among DEC stains in Southern India. Further studies are needed to evaluate the epidemiology and virulence properties of atypical EPEC strains.

    Gliomas represent the most common primary intraparenchymal tumors of the central nervous system in adults and children and are a genetic and phenotypic heterogeneous group. Large multi-institutional studies and The Cancer Genome Atlas have provided firm insights into the basic genetic drivers in gliomas. The main molecular biomarkers routinely applied to evaluate diffuse gliomas include MGMT promoter methylation, EGFR alterations (eg, EGFRvIII), IDH1 or IDH2 mutations, and 1p19q co-deletion. Many of these markers have become standard of care for molecular testing and prerequisites for clinical trial enrollment. Other recent biomarkers include TERT promoter and ATRX mutations, alterations that identify specific molecular subgroups of diffuse gliomas with biological and clinical relevance. It has also become apparent that distinctive patterns of molecular genetic evolution develop in the context of current therapeutic regimens. Important insights have also been uncovered in the field of pediatric glioma, including the identification of recurrent mutation, fusion, and/or duplication events of the BRAF, FGFR1, MYB, and MYBL1 genes in pediatric low-grade gliomas, mutations affecting histone components (H3F3A p.K27M or p.G34) in pediatric high-grade gliomas, and aggressive subsets developing in midline central nervous system structures. Here, we summarize current concepts in molecular testing for glial tumors, including recent findings by large-scale discovery efforts and technologic advances that are affecting routine diagnostic work.

  12. Does vitamin d deficiency contribute to the severity of asthma in children and adults

    International Nuclear Information System (INIS)

    Role of vitamin D in the health of bones has been well established for over decades. It was known that its deficiency caused rickets in children and osteomalacia in adults. Later it was discovered that these can be corrected by giving vitamin D. Researchers discovered that vitamin D can be synthesized by exposure to sun. Hence it was also named the sunshine vitamin. As time passed it was observed that low levels of vitamin D were associated with multiple diseases. This sparked the interest of the scientific community to further the research on vitamin D which led to the studies that started associating vitamin D with various diseases like cancers (prostate, colon and breast), autoimmune diseases (rheumatoid arthritis), infectious diseases (tuberculosis, hepatitis B, hepatitis C, HIV), cardiovascular diseases, mental illnesses (schizophrenia), diabetes mellitus (type 1, type 2 and gestational) and allergic conditions like asthma. With time, more studies were carried out relating levels of vitamin D to development of asthma, asthma exacerbations and risk factors leading to development of asthma like respiratory tract infections with positive associations. A number of studies were carried out which tried to explain the possible molecular mechanisms relating deficiency of vitamin D in pathogenesis of asthma. This review summarizes the role of vitamin D in development of asthma and probable mechanisms relating vitamin D to the pathogenesis of asthma. (author)

    Autologous hematopoietic cell transplantation (AutoHCT) is a potentially curative treatment modality for relapsed/refractory Hodgkin lymphoma (HL). However, no large studies have evaluated pretransplant factors predictive of outcomes of AutoHCT in children, adolescents and young adults (CAYA, age <30 years). In a retrospective study, we analyzed 606 CAYA patients (median age 23 years) with relapsed/refractory HL who underwent AutoHCT between 1995 and 2010. The probabilities of PFS at 1, 5 and 10 years were 66% (95% confidence interval (CI): 62-70), 52% (95% CI: 48-57) and 47% (95% CI: 42-51), respectively. Multivariate analysis for PFS demonstrated that at the time of AutoHCT patients with Karnofsky/Lansky score ⩾90, no extranodal involvement and chemosensitive disease had significantly improved PFS. Patients with time from diagnosis to first relapse of <1 year had a significantly inferior PFS. A prognostic model for PFS was developed that stratified patients into low-, intermediate- and high-risk groups, predicting for 5-year PFS probabilities of 72% (95% CI: 64-80), 53% (95% CI: 47-59) and 23% (95% CI: 9-36), respectively. This large study identifies a group of CAYA patients with relapsed/refractory HL who are at high risk of progression after AutoHCT. Such patients should be targeted for novel therapeutic and/or maintenance approaches post-AutoHCT. PMID:26237164

  5. Processing of complex distracting sounds in school-aged children and adults: Evidence from EEG and MEG data

    Directory of Open Access Journals (Sweden)

    Philipp eRuhnau

    2013-10-01

    Full Text Available When a perceiver performs a task, rarely occurring sounds often have a distracting effect on task performance. The neural mismatch responses in event-related potentials to such distracting stimuli depend on age. Adults commonly show a negative response, whereas in children a positive as well as a negative mismatch response has been reported. Using electro- and magnetoencephalography (EEG/MEG, here we investigated the developmental changes of distraction processing in school-aged children (9–10 years and adults. Participants took part in an auditory-visual distraction paradigm comprising a visuo-spatial primary task and task-irrelevant environmental sounds distracting from this task. Behaviorally, distractors delayed reaction times in the primary task in both age groups, and this delay was of similar magnitude in both groups. The neurophysiological data revealed an early as well as a late mismatch response elicited by distracting stimuli in both age groups. Together with previous research, this indicates that deviance detection is accomplished in a hierarchical manner in the auditory system. Both mismatch responses were localized to auditory cortex areas. All mismatch responses were generally delayed in children, suggesting that not all neurophysiological aspects of deviance processing are mature in school-aged children. Furthermore, the P3a, reflecting involuntary attention capture, was present in both age groups in the EEG with comparable amplitudes and at similar latencies, but with a different topographical distribution. This suggests that involuntary attention shifts towards complex distractors operate comparably in school-aged children and adults, yet undergoing generator maturation.

    Full Text Available Abstract Background Human bocavirus (HBoV is a newly discovered parvovirus associated with acute respiratory tract illness (ARTI and gastrointestinal illness. Our study is the first to analyze the characteristics of HBoV-positive samples from ARTI patients with a wide age distribution from Guangzhou, southern China. Methods Throat swabs (n=2811 were collected and analyzed from children and adults with ARTI over a 13-month period. The HBoV complete genome from a 60 year-old female patient isolate was also determined. Results HBoV DNA was detected in 65/2811 (2.3% samples, of which 61/1797 were from children (Mycoplasma pneumoniae had the highest frequency of 16.9% (11/65. Upper and lower respiratory tract illness were common symptoms, with 19/65 (29.2% patients diagnosed with pneumonia by chest radiography. All four adult patients had systemic influenza-like symptoms. Phylogenetic analysis of the complete genome revealed a close relationship with other HBoVs, and a more distant relationship with HBoV2 and HBoV3. Conclusions HBoV was detected from children and adults with ARTI from Guangzhou, southern China. Elderly people were also susceptive to HBoV. A single lineage of HBoV was detected among a wide age distribution of patients with ARTI.

  7. Developmental changes of prefrontal activation in humans: a near-infrared spectroscopy study of preschool children and adults.

    Directory of Open Access Journals (Sweden)

    Yuki Kawakubo

    Full Text Available Previous morphological studies indicated that development of the human prefrontal cortex (PFC appears to continue into late adolescence. Although functional brain imaging studies have sought to determine the time course of functional development of the PFC, it is unclear whether the developmental change occurs after adolescence to adulthood and when it achieves a peak because of the narrow or discontinuous range in the participant's age. Moreover, previous functional studies have not focused on the anterior frontal region, that is, the frontopolar regions (BA9/10. Thus, the present study investigated the developmental change in frontopolar PFC activation associated with letter fluency task by using near-infrared spectroscopy (NIRS, in subjects from preschool children to adults. We analyzed the relative concentration of hemoglobin (ΔHb in the prefrontal cortex measured during the activation task in 48 typically-developing children and adolescents and 22 healthy adults. Consistent with prior morphological studies, we found developmental change with age in the children/adolescents. Moreover, the average Δoxy-Hb in adult males was significantly larger than that in child/adolescent males, but was not true for females. These data suggested that functional development of the PFC continues into late adolescence. Although the developmental change of the frontopolar PFC was independent of gender from childhood to adolescence, in adulthood a gender difference was shown.

    Increases in glomerular size occur with normal body growth and in many pathologic conditions. In this study, we determined associations between glomerular size and numbers of glomerular resident cells, with a particular focus on podocytes. Kidneys from 16 male Caucasian-Americans without overt renal disease, including 4 children (≤3 years old) to define baseline values of early life and 12 adults (≥18 years old), were collected at autopsy in Jackson, Mississippi. We used a combination of immunohistochemistry, confocal microscopy, and design-based stereology to estimate individual glomerular volume (IGV) and numbers of podocytes, nonepithelial cells (NECs; tuft cells other than podocytes), and parietal epithelial cells (PECs). Podocyte density was calculated. Data are reported as medians and interquartile ranges (IQRs). Glomeruli from children were small and contained 452 podocytes (IQR=335-502), 389 NECs (IQR=265-498), and 146 PECs (IQR=111-206). Adult glomeruli contained significantly more cells than glomeruli from children, including 558 podocytes (IQR=431-746; Pnumber of podocytes in large glomeruli does not match the increase in glomerular size observed in adults, resulting in relative podocyte depletion. This may render hypertrophic glomeruli susceptible to pathology.

    2011-01-01

    Background Helicobacter pylori is an important agent of gastroduodenal disease in Africa and throughout the world. We sought to determine an optimum method for genotyping H. pylori strains from children and adults in The Gambia, West Africa. Results Virulence genes were amplified in 127 of 190 cases tested (121 adults and 6 children); each of 60 bacterial cultures, and 116 from DNA extracted directly from biopsies. The proportion of biopsies that were cagA+, the ratio of vacAs1/s2, and vacAm1/m2, and the proportion of mixed strain populations in individual subjects changed with age. Strains lacking virulence cagA and vacA genes and with apparently homogeneous (one predominant strain) infections were more common among infants than adults. Conclusions In order to detect the range of bacterial genotypes harbored by individual patients, direct PCR proved slightly superior to isolation of H. pylori by biopsy culture, but the techniques were complementary, and the combination of both culture and direct PCR produced the most complete picture. The seemingly higher virulence of strains from adult than infant infections in The Gambia merits further analysis. PMID:21507253

    AIM: To evaluate the serologic IgG response to H pylori and CagA across age groups and in healthy children and adults.METHODS: Totally, 386 children aged 1-15 years and 200 adults aged 20-60 years, were enrolled to study. The serum samples of participant were tested for presence of anti-//pylori and anti-CagA IgG by using ELJSA method.RESULTS: The seroprevalence of H pylori in adults was significantly higher than that observed in children (67.5% vs 46.6%; P < 0.000003). In children, the seropositivity rate in males (51.9%) was significantly (P < 0.05) higher than that observed in females (41.7%). The prevalence of serum anti-CagA antibody was 72.8% and 67.4% in infected children and adults, respectively. The mean titer of serum anti-CagA antibodies was significantly higher among children in comparison to adults (64.1 Uarb/mL vs 30.7; P < 0.03). In infected children and adults the prevalence of serum anti-CagA antibody was higher in males compared to females (78.4% vs 66.3%; P = 0.07 and 75.6% vs 54.71%; P < 0.04, respectively). The age-specific prevalence of anti-H pylori and anti-CagA antibody (in infected subjects) was 37.6% and 59.57% at age 1-5 years, 46.9% and 75% at age 6-10 years, 54.9% and 79.45% at age 11-15, 59.01% and 83.33% at age 20-30 years, 66.6% and 60.52% at age 31-40 years, 73.46% and 63.88% at age 41-50 years and 75.75% and 60% at age 51-60 years with mean titer of anti-CagA antibody of 75.94, 63.32, 57.11, 52.06, 23.62, 21.52 and 21.80 Uarb/mL, respectively. There was significant difference between mean serum anti-CagA antibody in age subgroups (P < 0.001).CONCLUSION: These results showed that anti-//pylori and anti-CagA antibodies were common in the children and adults. The///7y/0//-specific antibodies influenced by age and sex of subjects. Moreover, it seems that males are more susceptible to infection with CagA+ strains compared to females.

    Full Text Available AIM: To determine whether QuantiFERON®-TB Gold In-Tube (QFT can contribute to the diagnosis of active tuberculosis (TB in children in a high-burden setting and to assess the performance of QFT and tuberculin skin test (TST in a prospective cohort of TB suspect children compared to adults with confirmed TB in Tanzania. METHODS: Sensitivity and specificity of QFT and TST for diagnosing active TB as well as indeterminate QFT rates and IFN-γ levels were assessed in 211 TB suspect children in a Tanzanian district hospital and contrasted in 90 adults with confirmed pulmonary TB. RESULTS: Sensitivity of QFT and TST in children with confirmed TB was 19% (5/27 and 6% (2/31 respectively. In adults sensitivity of QFT and TST was 84% (73/87 and 85% (63/74. The QFT indeterminate rate in children and adults was 27% and 3%. Median levels of IFN-γ were lower in children than adults, particularly children <2 years and HIV infected. An indeterminate result was associated with age <2 years but not malnutrition or HIV status. Overall childhood mortality was 19% and associated with an indeterminate QFT result at baseline. CONCLUSION: QFT and TST showed poor performance and a surprisingly low sensitivity in children. In contrast the performance in Tanzanian adults was good and comparable to performance in high-income countries. Indeterminate results in children were associated with young age and increased mortality. Neither test can be recommended for diagnosing active TB in children with immature or impaired immunity in a high-burden setting.

    Full Text Available OBJECTIVE: The aims of this study were to estimate the frequency of left ventricular hypertrophy and to identify variables associated with this condition in under 25-year-old patients with sickle cell anemia.METHODS: A cross-sectional study was performed of children, adolescents and young adults with sickle cell anemia submitted to a transthoracic Doppler echocardiography. The mass of the left ventricle was determined by the formula of Devereux et al. with correction for height, and the percentile curves of gender and age were applied. Individuals with rheumatic and congenital heart disease were excluded. The patients were divided into two groups according to the presence or absence of left ventricular hypertrophy and compared according to clinical, echocardiographic and laboratory variables.RESULTS: A total of 37.6% of the patients had left ventricular hypertrophy in this sample. There was no difference between the groups of patients with and without hypertrophy according to pathological history or clinical characteristics, except possibly for the use of hydroxyurea, more often used in the group without left ventricular hypertrophy. Patients with left ventricular hypertrophy presented larger left atria and lower hemoglobin and hematocrit levels, reticulocyte index and a higher albumin:creatinine ratio in urine.CONCLUSION: Left ventricular hypertrophy was observed in more than one-third of the young patients with sickle cell anemia with this finding being inversely correlated to the hemoglobin and hematocrit levels, and reticulocyte index and directly associated to a higher albumin/creatinine ratio. It is possible that hydroxyurea had had a protective effect on the development of left ventricular hypertrophy.

We studied retrospectively all patients less than age 30 at our institution treated consecutively with LC for medulloblastoma (MB), primitive neuroectodermal tumor (PNET), and atypical teratoid rhabdoid tumor (ATRT). Seventeen patients received LC (2 mg/kg up to 50 mg, every 2 weeks to monthly) at diagnosis of high-risk CNS embryonal tumor (2 PNET, 3 ATRT) or relapse of MB (12 MB; 9 had leptomeningeal metastases). Sixteen patients received concurrent systemic chemotherapy. A total of 108 doses were administered (IT 82, intraventricular 26) with a mean of six (range 1-16) treatments per patient. Only three administrations were associated with adverse effects of arachnoiditis or headache. None developed malignant cerebrospinal fluid (CSF) cytology while receiving LC. All the six evaluable patients with malignant CSF cytology and treated with at least two doses cleared their CSF (mean 3 doses, range 1-5). Median overall survival in relapse patients was 9.1 months. Five patients (4 de novo and 1 relapsed) remain alive in complete remission for a median 26.8 months from first LC. Liposomal cytarabine is an easily administered, well-tolerated, and active drug in patients with high-risk embryonal neoplasms. One-third of our cohort remains in remission from otherwise fatal diagnoses. Our findings warrant a phase II trial of LC in newly diagnosed or recurrent CNS embryonal tumors. PMID:20859651

    The use of physical punishment for children is associated with poor psychological and behavioral outcomes, but the causal pathway is controversial, and the effects on later physical health unknown. We conducted a cross-sectional survey of asthma, cancer, and cardiac patients (150 in each category, 75 male) recruited from outpatient clinics and 250 healthy controls (125 male). All participants were 40-60 years old and citizens of Saudi Arabia, where the use of beating and insults is an acceptable parenting style. Demographic data and recalled frequency of beatings and insults as a child were assessed on an 8-point scale. Beating and insults were highly correlated (ρ = 0.846). Propensity score matching was used to control for demographic differences between the disease and healthy groups. After controlling for differences, more frequent beating (once or more per month) and insults were associated with a significantly increased risk for cancer (RR = 1.7), cardiac disease (RR = 1.3) and asthma (RR = 1.6), with evidence of increased risk for cancer and asthma with beating frequency of once every 6 months or more. Our results show that a threatening parenting style of beating and insults is associated with increased risk for somatic disease, possibly because this form of parenting induces stress. Our findings are consistent with previous research showing that child abuse and other early life stressors adversely affect adult somatic health, but provide evidence that the pathogenic effects occur also with chronic minor stress. A stress-inducing parenting style, even when normative, has long term adverse health consequences. PMID:23054177

    Full Text Available Angry faces are perceived as more masculine by adults. However, the developmental course and underlying mechanism (bottom-up stimulus driven or top-down belief driven associated with the angry-male bias remain unclear. Here we report that anger biases face gender categorization towards male responding in children as young as 5-6 years. The bias is observed for both own- and other-race faces, and is remarkably unchanged across development (into adulthood as revealed by signal detection analyses (Experiments 1-2. The developmental course of the angry-male bias, along with its extension to other-race faces, combine to suggest that it is not rooted in extensive experience, e.g. observing males engaging in aggressive acts during the school years. Based on several computational simulations of gender categorization (Experiment 3, we further conclude that (1 the angry-male bias results, at least partially, from a strategy of attending to facial features or their second-order relations when categorizing face gender, and (2 any single choice of computational representation (e.g., Principal Component Analysis is insufficient to assess resemblances between face categories, as different representations of the very same faces suggest different bases for the angry-male bias. Our findings are thus consistent with stimulus-and stereotyped-belief driven accounts of the angry-male bias. Taken together, the evidence suggests considerable stability in the interaction between some facial dimensions in social categorization that is present prior to the onset of formal schooling.

However, the developmental course and underlying mechanism (bottom-up stimulus driven or top-down belief driven) associated with the angry-male bias remain unclear.

    The Monell two-series, forced-choice, paired-comparison tracking method provides a reliable measure of sweet taste preferences from childhood to adulthood. The method, which is identical for children, adolescents, and adults, is of short duration (language development, making this method amenable to the cognitive limitations of pediatric populations. In this whole-mouth tasting method, subjects are asked to taste (without swallowing) pairs of solutions of different sucrose concentrations and to point to the solution they prefer. Each subsequent pair contains the participant's preceding preferred concentration and an adjacent stimulus concentration. The procedure continues until the subject chooses either a given concentration of sucrose when paired with both a higher and a lower concentration, or the highest or lowest concentration two consecutive times. Subjects are prevented from reaching response criteria on the basis of first or second position bias by the two-series design of the method, which counterbalances the order of solution presentation within each pair between the series (the weaker concentration is presented first in Series 1, second in Series 2). The geometric mean of the two sucrose concentrations chosen in Series 1 and 2 is an estimate of the participant's most preferred level of sucrose. Sucrose preference as determined with this laboratory-based measure has been shown to be associated with preference for sugars in foods and beverages and with taste receptor genotype, family history of alcoholism, and race/ethnicity, as well as depressive symptomatology among pediatric populations. The method has real-world relevance and has been applied to determine most preferred level of other tastes (e.g., salt), making it a valuable psychophysical tool. PMID:27501332

    Concern for impaired bone health in children with neurofibromatosis type 1 (NF-1) has led to increased interest in bone densitometry in this population. Our study assessed bone mineral apparent density (BMAD) and whole-body bone mineral content (BMC)/height in pediatric patients with NF-1 with a high plexiform neurofibroma burden. Sixty-nine patients with NF-1 (age range 5.2-24.8; mean 13.7 ± 4.8 years) were studied. Hologic dual-energy X-ray absorptiometry scans (Hologic, Inc., Bedford, MA, USA) were performed on all patients. BMD was normalized to derive a reference volume by correcting for height through the use of the BMAD, as well as the BMC. BMAD of the lumbar spine (LS 2-4), femoral neck (FN), and total body BMC/height were measured and Z-scores were calculated. Impaired bone mineral density was defined as a Z-score ≤-2. Forty-seven percent of patients exhibited impaired bone mineral density at any bone site, with 36% at the LS, 18% at the FN, and 20% total BMC/height. BMAD Z-scores of the LS (-1.60 ± 1.26) were more impaired compared with both the FN (-0.54 ± 1.58; P=0.0003) and the whole-body BMC/height Z-scores (-1.16 ± 0.90; P=0.036). Plexiform neurofibroma burden was negatively correlated with LS BMAD (r(s)=-0.36, P=0.01). In pediatric and young adult patients with NF-1, LS BMAD was more severely affected than the FN BMAD or whole-body BMC/height.

    Parental alcohol use disorders (AUDs) have been conceptualized as a chronic stressor that can lead to deleterious long-term outcomes in children of individuals with AUDs. Yet, while many individuals are detrimentally affected by their parents' problematic alcohol use, and go on to manifest psychological problems, others do not. How individuals cope with the stress of having a parent with an AUD is believed to be an important moderator of this differential outcome. This study assessed whether individuals' alcohol-specific coping styles predicted alcohol use, positive or negative life events, and depression, using a sample of 465 college students, of whom 20% were adult children of individuals with alcohol use disorders, colloquially known as adult children of alcoholics (ACOAs), and a battery of well-validated, self-report measures. Participant ACOAs reported less 'engaged' and 'total' alcohol-specific coping strategies and more 'withdrawal' alcohol-specific coping strategies than their non adult children of alcoholics (NACOAs) counterparts. Across participants, women reported more 'engaged', 'tolerant/inactive', and 'total' coping than men. Although ACOAs reported significantly more negative life events, which predicted more passive coping styles, they did not differ significantly from NACOAs on measures of problematic alcohol use or depression, supporting theories of resilience in ACOAs regardless of their alcohol-specific coping styles. For NACOAs, 'tolerant' coping predicted greater depression and alcohol-related problems; 'engaged' coping predicted fewer alcohol problems. Results suggest that ACOAs cope differently with problematic alcohol use among relatives and friends compared with NACOAs and are more likely to experience negative life events. Additionally, alcohol-related coping strategies have more predictive utility in NACOAs than ACOAs. PMID:25802055

    OBJECTIVES Optimal vitamin D status is known to have beneficial health effects and vitamin D supplements are commonly used. It has been suggested that vitamin D supplementation may increase blood lead in children and adults with previous lead exposure. The objective was to determine the safety regarding lead toxicity during 12 weeks of high dose vitamin D3 supplementation in children and young adults with HIV. METHODS Subjects with HIV (age 8 to 24 yrs) were randomized to vitamin D3 supplementation of 4000 IU/day or 7000 IU/day and followed at 6 and 12 weeks for changes in 25D and whole blood lead concentration. This was a secondary analysis of a larger study of vitamin D3 supplementation in children and adolescents with HIV. RESULTS In 44 subjects (75% African American), the baseline mean ± SD serum 25D was 48.3 ± 18.6 nmol/L. 50% of subjects had baseline serum 25D 5.0 μg/dL at baseline or during subsequent visits. Whole blood lead and 25D were not correlated at baseline, and were negatively correlated after 12 weeks of supplementation (p= 0.014). Whole blood lead did not differ between those receiving 4000 IU versus 7000 IU of vitamin D3. CONCLUSION High dose vitamin D3 supplementation and the concomitant increased serum 25D did not result in increased whole blood lead concentration in this sample of children and young adults living in a northeastern urban city.

    13-valent-pneumococcal conjugated vaccine was recently approved in the USA and Europe for adults 50 years of age or more. But this approval was followed by recommendations limiting its use to immunocompromised and asplenic patients. The extension of indications to adults was based on the well-demonstrated clinical effectiveness in infants less than 2 years of age, and on a better immune response either quantitatively or qualitatively with conjugated vaccines compared to the immunogenicity of plain polysaccharide vaccines. Nevertheless, the issue was to know whether results observed with the 7-valent pneumococcal conjugate vaccine in children are reproducible in adults with the 13-valent. The answer was given by comparing the epidemiological and physiopathological data, and the immunological response of the two populations. Very few clinical effectiveness studies in adults are available. We had for aim to assess these various issues in infants and adults. A lot of questions remain, such as the unknown impact of serotype replacement with the 13-valent pneumococcal conjugated vaccine on the clinical epidemiology and emergent Streptococcus pneumoniae pathogenicity, while waiting for the CAPITA study results expected in 2014.

    Background & Objective : Nutrient excess and nutrient deficiency in the diets of preschool children can lead to permanent modification of metabolic pathways and increased risk of diet-dependent diseases in adults. Children are most susceptible to the adverse consequences of bad eating habits.The objective of this study was to evaluate the eating habits and the diets of preschool children as risk factors for excessive weight, obesity, insulin resistance and the metabolic syndrome. Methods : The study was conducted on 350 randomly selected preschool children attending kindergartens in south-eastern Poland. Three-day dietary recalls were processed and evaluated in the Dieta 5 application. Results : The analyzed diets were characterized by low diversity and a high share of processed foods, such as pate, sausages, ketchup, mayonnaise, fried meat, French fries and fast-food. The dietary content of vegetables, raw fruit, dairy products and whole grain products was alarmingly low. Conclusions : Diets characterized by excessive energy value and nutritional deficiency can lead to health problems. In most cases, excessive weight gain in children can be blamed on parents and caretakers who are not aware of the health consequences of high-calorie foods rich in fats and sugar.

    Background: Catheter ablation has been used to manage supraventricular arrhythmia in children since 1990. This article reviews the history of catheter ablation used to treat arrhythmia in children and discusses new frontiers in the field. We also address ablation in adult patients with a history of congenital heart disease (CHD) that was diagnosed and initially treated in childhood. Methods: We conducted an evidence-based literature review to gather available data on ablation for supraventricular tachycardia in children and adult patients with CHD. Results: Ablations can be performed safely and effectively in children. Complication rates are higher in children arrhythmia. A paucity of data is available on ablation in adult patients with CHD. Conclusion: Electrophysiology for pediatric and adult patients with CHD is a rapidly growing and progressing field. We benefit from continuous development of ablation techniques for adults with structurally normal hearts and have the unique challenge and responsibility to ensure the safe and effective application of these techniques in the vulnerable population of pediatric and adult patients with CHD.

    Human immunodeficiency virus (HIV) infection causes dysfunction of different organ systems. Myocardial diastolic dysfunction has been reported previously in an adult HIV population. Our aim was to study myocardial strain in children and young adults infected by HIV who have apparently normal ejection fraction. Forty HIV-infected patients (mean age 20.6 ± 1.5 years) with normal ejection fraction and 55 matched normal controls (mean age 17 ± 1.5 years) were studied by two-dimensional echocardiogram. The images were stored then exported to velocity vector imaging software for analysis. Measures considered were left-ventricular peak global systolic strain (LV S) and strain rate (LV SR) as well as right-ventricular peak global systolic strain (RV S) and strain rate (RV SR). Circumferential measures of the left ventricle included the following: LV circumferential peak global systolic strain (LV circ S), strain rate (LV circ SR), radial velocity (LV rad vel), and rotational velocity (LV rot vel) at the level of the mitral valve. Statistical significance was set at p strain and strain rate in children and young adults. Normal ejection fraction might be attributed to preserved circumferential myocardial deformation. Strain and strain rate may help identify HIV patients at high risk for cardiac dysfunction and allow early detection of silent myocardial depression.

    Chronic neurological disorders in children have significant effects on adult medical and social function. Transition from pediatric to adult services is a complex process. No objective data are available to inform physicians about the most effective approach. Nevertheless the most recommended approach is a joint pediatric/adult transition clinic. Malnutrition, either under or overnutrition, is a common condition among neurologically impaired children. Undernutrition is most prevalent, and its causes are diverse: insufficient caloric intake, excessive nutrient losses and abnormal energy metabolism. Malnutrition is associated with significant morbidity, while nutritional rehabilitation improves overall health as well as quality of life. It is not easy to determine which the nutritional needs in these patients are. Besides, they often present difficulties for oral feeding, mainly due to oromotor dysfunction. Gastrointestinal symptoms, gastro esophageal reflux and constipation, as well as spasticity, scoliosis and joint deformities contribute to these difficulties. Because of that, an assessment of nutritional status should be performed periodically, and to assess efficacy and security of oral intake. If modifying oral diet we cannot confirm an adequate support, a nasogastric tube or a gastrostomy need to be considered. Often, a fundoplication is associated to the placement of a gastrostomy. Although the outcomes in a better nutritional status and quality of life are often obtained, it is not an easy decision for families. PMID:25077342

    We investigated the accuracy of auditory inferences of personality of Belgian children with vocal fold nodules (VFN). External judges (n = 57) were asked to infer the personality of normophonic (NP) children and children with VFN (n = 10) on the basis of vowels and sentences. The auditory inferred profiles were compared to the actual personality of NP and VFN children. Positive and partly accurate inferences of VFN children's personality were made on the basis of connected speech, while sustained vowels yielded negative and inaccurate inferences of personality traits of children with VFN. Dysphonic voice quality, as defined by the overall severity of vocal abnormality, conveyed inaccurate and low degrees of extraversion. This effect was counterbalanced in connected speech by faster speaking rate that accurately conveyed higher degrees of extraversion, a characteristic trait of VFN children's actual personality.

    Many studies show that Juvenile Idiopathic Arthritis (JIA) is associated with early subclinical signs of atherosclerosis. Chronic inflammation per se may be an important driver but other known risk factors, such as dyslipidemia, hypertension, insulin insensitivity, a physically inactive lifestyle, obesity, and tobacco smoking may also contribute substantially. We performed a systematic review of studies through the last 20 years on early signs of subclinical atherosclerosis in children and adolescents with JIA with the purpose of investigating whether possible risk factors, other than inflammation, were considered.We found 13 descriptive cross sectional studies with healthy controls, one intervention study and two studies on adults diagnosed with JIA. Only one study addressed obesity, and physical activity (PA) has only been assessed in one study on adults with JIA and only by self-reporting. This is important as studies on PA in children with JIA have shown that most patients are less physically active than their healthy peers, and as physical inactivity in several large studies of normal schoolchildren is found to be associated with increased clustering of risk factors for cardiovascular disease. It is thus possible that an inactive lifestyle in patients with JIA is an important contributor to development of the subclinical signs of atherosclerosis seen in children with JIA, and that promotion of an active lifestyle in childhood and adolescence may diminish the risk for premature atherosclerotic events in adulthood.

    Low vitamin D levels in elderly people are associated with reduced bone mass, secondary hyperparathyroidism, and increased fracture risk. Its effect on the growing skeleton is not well known. The aim of this study was to evaluate the possible influence of chronic winter vitamin D deficiency and higher winter parathyroid hormone (PTH) levels on bone mass in prepubertal children and young adults. The study was carried out in male and female Caucasian subjects. A total of 163 prepubertal children (X age +/- 1 SD: 8.9 +/- 0.7 years) and 234 young adults (22.9 +/- 3.6 years) who had never received vitamin D supplementation were recruited from two areas in Argentina: (1)Ushuaia (55 degrees South latitude), where the population is known to have low winter 25OHD levels and higher levels of PTH in winter than in summer, and (2)Buenos Aires (34 degrees S), where ultraviolet (UV) radiation and vitamin D nutritional status in the population are adequate all year round. Bone mineral content (BMC) and bone mineral density (BMD) of the ultradistal and distal radius were measured in the young adults. Only distal radius measurements were taken in the children. Similar results were obtained in age-sex matched groups from both areas. The only results showing significant difference corresponded to comparison among the Ushuaian women: those whose calcium (Ca) intake was below 800 mg/day presented lower BMD and BMC values than those whose Ca intake was above that level (0.469 +/- 0.046 versus 0.498 +/- 0.041 g/cm(2), P Ushuaia and Buenos Aires in spite of the previously documented difference between both areas regarding UV radiation and winter vitamin D status. BMD of axial skeletal areas as well the concomitant effect of a low Ca diet and vitamin D deficiency on the growing skeleton should be studied further. PMID:10954776

    Full Text Available New sources of caffeine, besides coffee and tea, have been introduced into the US food supply. Data on caffeine consumption age and purchase location can help guide public health policy. National Health and Nutrition Examination Surveys (NHANES were used to estimate population-level caffeine intakes, using data from 24-h dietary recall. First, caffeine intakes by age-group and beverage type were estimated using the most recent 2011–2012 data (n = 7456. Second, fourteen years trends in caffeine consumption, overall and by beverage type, were evaluated for adults and children. Trend analyses were conducted by age groups. Last, trends in caffeine intakes by purchase location and beverage type were estimated. In 2011–2012, children aged four to eight years consumed the least caffeine (15 mg/day, and adults aged 51–70 years consumed the most (213 mg/day. The population mean (age ≥ four years was 135 mg/day, driven largely by coffee (90 mg/day, tea (25 mg/day, and soda (21 mg/day. For the 14–19 years and 20–34 years age-groups, energy drinks contributed 6 mg/day (9.9% and 5 mg/day (4.5%, respectively. The bulk of caffeine came from store-bought coffee and tea. Among both children and adults combined, caffeine intakes declined from 175 mg/day (1999–2000 to 142 mg/day (2011–2012, largely driven by a drop in caffeine from soda (41 mg/day to 21 mg/day. Store-bought coffee and tea remain principal drivers of caffeine intake in the US. Sodas and energy drinks make minor contributions to overall caffeine intakes.

    BACKGROUND: Little is known about the long-term consequences of positive wellbeing in childhood in the general population. We used the MRC National Survey of Health and Development (the British 1946 birth cohort) to test associations between adolescent positive wellbeing and social functioning in midlife. METHOD: Temperament and behaviour at ages 13 and 15 years were rated by school teachers on a range of criteria. These mostly referred to absence or presence of conduct and emotional problems, but four items allowed positive ratings: 'very popular with other children', 'unusually happy and contented', 'makes friends extremely easily' and 'extremely energetic, never tired'. In addition, at age 16 years survey members self-completed the Maudsley Personality Inventory, from which a summary measure of extraversion was derived, as this was previously found to be associated with midlife positive wellbeing in this cohort. RESULTS: Being a happy child, defined as receiving at least two of the above teacher ratings, was positively associated with midlife functioning and wellbeing, specifically a low probability of lifetime emotional problems, a high frequency of contact with friends or relatives, engagement in social activities, and to a lesser extent feeling satisfied with accomplishments in working life. These associations were independent of father's social class, childhood cognition, educational attainment, and midlife occupational social class. There were no independent associations between being a happy child and educational or occupational attainment, being married, engagement in prosocial activities, taking leadership in community activities, and with life satisfaction in general or with family life. Extraversion was associated with a low probability of lifetime emotional problems, high engagement in social activities, being married, general midlife life satisfaction, and satisfaction with family life, but not with social contact, prosocial activity, leadership

    Full Text Available OBJECTIVES: Use electronic health records Autism Spectrum Disorder (ASD to assess the comorbidity burden of ASD in children and young adults. STUDY DESIGN: A retrospective prevalence study was performed using a distributed query system across three general hospitals and one pediatric hospital. Over 14,000 individuals under age 35 with ASD were characterized by their co-morbidities and conversely, the prevalence of ASD within these comorbidities was measured. The comorbidity prevalence of the younger (Age<18 years and older (Age 18-34 years individuals with ASD was compared. RESULTS: 19.44% of ASD patients had epilepsy as compared to 2.19% in the overall hospital population (95% confidence interval for difference in percentages 13.58-14.69%, 2.43% of ASD with schizophrenia vs. 0.24% in the hospital population (95% CI 1.89-2.39%, inflammatory bowel disease (IBD 0.83% vs. 0.54% (95% CI 0.13-0.43%, bowel disorders (without IBD 11.74% vs. 4.5% (95% CI 5.72-6.68%, CNS/cranial anomalies 12.45% vs. 1.19% (95% CI 9.41-10.38%, diabetes mellitus type I (DM1 0.79% vs. 0.34% (95% CI 0.3-0.6%, muscular dystrophy 0.47% vs 0.05% (95% CI 0.26-0.49%, sleep disorders 1.12% vs. 0.14% (95% CI 0.79-1.14%. Autoimmune disorders (excluding DM1 and IBD were not significantly different at 0.67% vs. 0.68% (95% CI -0.14-0.13%. Three of the studied comorbidities increased significantly when comparing ages 0-17 vs 18-34 with p<0.001: Schizophrenia (1.43% vs. 8.76%, diabetes mellitus type I (0.67% vs. 2.08%, IBD (0.68% vs. 1.99% whereas sleeping disorders, bowel disorders (without IBD and epilepsy did not change significantly. CONCLUSIONS: The comorbidities of ASD encompass disease states that are significantly overrepresented in ASD with respect to even the patient populations of tertiary health centers. This burden of comorbidities goes well beyond those routinely managed in developmental medicine centers and requires broad multidisciplinary management that payors and

    Full Text Available This paper discusses the communicative competence of deaf children. It illustrates the process in which such children build narrative texts in interaction with a deaf teacher, and presents the diversity of this process due to the shared vs. non-shared perception of a picture - the source of the topic. Detailed analyses focus on the formal and semantic aspect of the stories, including the length of the text in sign language, the content selected, information categories, and types of answers to the teacher’s questions. This text is our contribution in memory of Professor Grace Wales Shugar, whose idea of dual agentivity of child-adult interaction inspired the research presented here.

    2016-01-01

    No commercial vaccine exists against Group A streptococci (GAS; Streptococcus pyogenes) and only little is known about anti-GAS protective immunity. In our effort to discover new protective vaccine candidates, we selected 21 antigens based on an in silico evaluation. These were all well......-conserved among different GAS strains, upregulated in host-pathogen interaction studies, and predicted to be extracellular or associated with the surface of the bacteria. The antigens were tested for both antibody recognition and T cell responses in human adults and children. The antigenicity of a selected group...

  7. Specific serum immunoglobulin g to chlamydia pneumoniae in healthy children and adults (south-east of iran)

    International Nuclear Information System (INIS)

    Chlamydia pneumoniae (C. pneumonia) is an obligate intracellular bacterium and recognized as a risk factor for several diseases such as asthma, atherosclerosis and arthritis. The aim of this study was to determine the sero-prevalence of C. pneumonia in healthy subjects in different age groups. Methods: The serum levels of anti C. pneumonia IgG were measured by using of ELISA. Results: Totally, 630 subjects (164 children and 466 adults) were included into study. The sero-prevalence and the mean titer of anti C. pneumonia antibody were 11.3% and 14.48 ± 2.18 RU/mL; at age = 10 years, 15% and 17.47 ± 2.40 RU/mL at age 11-20 years, 21% and 25.15 ± 4.56 RU/mL at age 21-30 years group, 40% and 53.77 ± 6.40 RU/mL at age 31-40 years, 94% and 146.41 ± 8.95 RU/mL at age 41-50 years, 98% and 153.59+-10.38 RU/mL at age 51-60 years, 96% and 138.80 ± 12.78 RU/mL at age 61-70 years, respectively. The differences of the sero-prevalence and the mean titer of anti C. pneumonia antibody between age groups were significant (p<0.0001). The sero-prevalence and the mean titer of anti C. pneumonia antibody were 11.6% and 14.33 ± 1.49 RU/mL in children and 65.5% and 97.40 ± 4.46 RU/mL in adults. The sero-prevalence and the mean titer of anti C. pneumonia antibody were significantly higher in adults in comparison with those in children (p<0.0001). Conclusion: These findings showed that the sero-prevalence and titer of anti C. pneumonia IgG were increased with advanced ages and were higher in adults as compared to children. (author)

    Full Text Available OBJECTIVE: We aimed to assess the effects of age, sex, body mass index (BMI, and anatomical site on skin thickness in children and adults with diabetes. METHODS: We studied 103 otherwise healthy children and adolescents with type 1 diabetes aged 5-19 years, and 140 adults with type 1 and type 2 diabetes aged 20-85 years. The thicknesses of both the dermis and subcutis were assessed using ultrasound with a linear array transducer, on abdominal and thigh skin. RESULTS: There was an age-related thickening of both dermis (p<0.0001 and subcutis (p = 0.013 in children and adolescents. Girls displayed a substantial pubertal increase in subcutis of the thigh (+54%; p = 0.048 and abdomen (+68%; p = 0.009. Adults showed an age-related decrease in dermal (p = 0.021 and subcutis (p = 0.009 thicknesses. Pubertal girls had a thicker subcutis than pubertal boys in both thigh (16.7 vs 7.5 mm; p<0.0001 and abdomen (16.7 vs 8.8 mm; p<0.0001. Men had greater thigh dermal thickness than women (1.89 vs 1.65 mm; p = 0.003, while the subcutis was thicker in women in thigh (21.3 vs 17.9 mm; p = 0.012 and abdomen (17.7 vs 9.8 mm; p<0.0001. In boys, men, and women, both dermis and subcutis were thicker on the abdomen compared to thigh; in girls this was only so for dermal thickness. In both children and adults, the skin (dermis and subcutis became steadily thicker with increasing BMI (p<0.0001. CONCLUSIONS: Skin thickness is affected by age, pubertal status, gender, BMI, and anatomical site. Such differences may be important when considering appropriate sites for dermal/subcutaneous injections and other transdermal delivery systems.

  9. Evaluation of joints in the lower limbs in adults and children using bone SPECT: Technical aspects and results

    International Nuclear Information System (INIS)

    Optimization procedures for and results of single photon emission computed tomography (SPECT) bone scintigraphy scans of the lower limbs are discussed. A group of patients was selected comprising 12 adults with chronic knee pain and 11 children with disorders which might affect growth cartilage. For the latter, it was proposed to evaluate the global and localized activity of the physics using SPECT with post-processing in three dimensions. These results are important in that they may directly influence the decision whether or not to proceed with orthopedic treatment or surgery, the aim being to prevent or predict dysmetrias and secondary deformities caused by various pathologies.

  10. Adenovirus-36 is associated with obesity in children and adults in Sweden as determined by rapid ELISA.

    Directory of Open Access Journals (Sweden)

    Malin Almgren

    Full Text Available BACKGROUND: Experimental and natural human adenovirus-36 (Adv36 infection of multiple animal species results in obesity through increasing adipogenesis and lipid accumulation in adipocytes. Presence of Adv36 antibodies detected by serum neutralization assay has previously been associated with obesity in children and adults living in the USA, South Korea and Italy, whereas no association with adult obesity was detected in Belgium/The Netherlands nor among USA military personnel. Adv36 infection has also been shown to reduce blood lipid levels, increase glucose uptake by adipose tissue and skeletal muscle biopsies, and to associate with improved glycemic control in non-diabetic individuals. PRINCIPAL FINDINGS: Using a novel ELISA, 1946 clinically well-characterized individuals including 424 children and 1522 non-diabetic adults, and 89 anonymous blood donors, residing in central Sweden representing the population in Stockholm area, were studied for the presence of antibodies against Adv36 in serum. The prevalence of Adv36 positivity in lean individuals increased from ∼7% in 1992-1998 to 15-20% in 2002-2009, which paralleled the increase in obesity prevalence. We found that Adv36-positive serology was associated with pediatric obesity and with severe obesity in females compared to lean and overweight/mildly obese individuals, with a 1.5 to 2-fold Adv36 positivity increase in cases. Moreover, Adv36 positivity was less common among females and males on antilipid pharmacological treatment or with high blood triglyceride level. Insulin sensitivity, measured as lower HOMA-IR, showed a higher point estimate in Adv36-positive obese females and males, although it was not statistically significant (p = 0.08. CONCLUSION: Using a novel ELISA we show that Adv36 infection is associated with pediatric obesity, severe obesity in adult females and lower risk of high blood lipid levels in non-diabetic Swedish individuals.

    Background Several studies have identified multiple obesity-associated loci mainly in European populations. However, their contribution to obesity in other ethnicities such as Mexicans is largely unknown. The aim of this study was to examine 26 obesity-associated single-nucleotide polymorphisms (SNP) in a sample of Mexican mestizos. Methods 9 SNPs in biological candidate genes showing replications (PPARG, ADRB3, ADRB2, LEPR, GNB3, UCP3, ADIPOQ, UCP2, and NR3C1), and 17 SNPs in or near genes associated with obesity in first, second and third wave GWAS (INSIG2, FTO, MC4R, TMEM18, FAIM2/BCDIN3, BDNF, SH2B1, GNPDA2, NEGR1, KCTD15, SEC16B/RASAL2, NPC1, SFRF10/ETV5, MAF, PRL, MTCH2, and PTER) were genotyped in 1,156 unrelated Mexican-Mestizos including 683 cases (441 obese class I/II and 242 obese class III) and 473 normal-weight controls. In a second stage we selected 12 of the SNPs showing nominal associations with obesity, to seek associations with quantitative obesity-related traits in 3 cohorts including 1,218 Mexican Mestizo children, 945 Mexican Mestizo adults, and 543 Indigenous Mexican adults. Results After adjusting for age, sex and admixture, significant associations with obesity were found for 6 genes in the case-control study (ADIPOQ, FTO, TMEM18, INSIG2, FAIM2/BCDIN3 and BDNF). In addition, SH2B1 was associated only with class I/II obesity and MC4R only with class III obesity. SNPs located at or near FAIM2/BCDIN3, TMEM18, INSIG2, GNPDA2 and SEC16B/RASAL2 were significantly associated with BMI and/or WC in the combined analysis of Mexican-mestizo children and adults, and FTO locus was significantly associated with increased BMI in Indigenous Mexican populations. Conclusions Our findings replicate the association of 8 obesity-related SNPs with obesity risk in Mexican adults, and confirm the role of some of these SNPs in BMI in Mexican adults and children.

  16. The Disruption of Subsistence Agricultural Systems in Rural Yucatan, Mexico may have Contributed to the Coexistence of Stunting in Children with Adult Overweight and Obesity.

    Gurri, Francisco D

    2015-12-01

    This paper attempts to link last century's disruption of local agricultural systems to today's presence of childhood under nutrition and adult overweight and obesity in the Yucatan Peninsula. It first compares Height for Age (H/A), Weight for Age (W/A) and Body Mass Index (BMI) of children from three rural populations in Yucatan and Campeche, Mexico whose subsistence strategy had been altered to different degrees since 1970. It then compares BMI in adults, in the same regions, born before and after the alteration of their environment in the 1970's. Children in the least disrupted zone were taller and had lower BMI than children in the other two, but were not heavier than children from the richest disrupted zone. Children in the poorest disrupted zone were shorter and lighter than the rest. BMI in adult men was higher in the two most disrupted zones only in those cohorts that grew up after the traditional agricultural regime was altered. It is concluded that disruptions of staple-based subsistence agriculture promoted a stockier phenotype in children and a tendency to accumulate body fat. Persistence of these conditions in the twenty first century has favored the coexistence of stunting during childhood with adults who easily become overweight.
