    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.

    1992-12-01

    A Franklian approach to treatment with adults who were molested as children recognizes that the trauma client's experiences of trauma and terror as a child can be transformed to discover real meaning potentials in the adult's daily life. In this paper the authors present a five-stage treatment approach based upon the Logotherapy concepts of Viktor Frankl which they have found to be helpful with adult survivors of childhood sexual abuse. Case material is presented to illustrate the described intervention approach.

    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.

  6. Do young children have adult syntactic competence?

    Science.gov (United States)

    Tomasello, M

    2000-03-14

    Many developmental psycholinguists assume that young children have adult syntactic competence, this assumption being operationalized in the use of adult-like grammars to describe young children's language. This "continuity assumption" has never had strong empirical support, but recently a number of new findings have emerged - both from systematic analyses of children's spontaneous speech and from controlled experiments - that contradict it directly. In general, the key finding is that most of children's early linguistic competence is item based, and therefore their language development proceeds in a piecemeal fashion with virtually no evidence of any system-wide syntactic categories, schemas, or parameters. For a variety of reasons, these findings are not easily explained in terms of the development of children's skills of linguistic performance, pragmatics, or other "external" factors. The framework of an alternative, usage-based theory of child language acquisition - relying explicitly on new models from Cognitive-Functional Linguistics - is presented.

    2014-03-01

    Adults distinguish sarcasm from literal language according to intonation involving a reduction in fundamental frequency (F0). We examined whether children's and adults' interpretation of a sarcastic speaker's belief, attitude, and humor was affected by degree of F0 reduction by presenting five- to six-year-olds and adults with sarcastic and literal criticisms with a small, medium, or large mean F0 reduction. Children and adults were more accurate in attributing the speaker's belief and intent for sarcastic criticisms for large F0 reductions compared to small reductions. These results show that F0 reduction is a helpful cue to sarcasm interpretation for both children and adults.

  20. 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.

  1. 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.

  2. Neural correlates of letter reversal in children and adults.

    Children often make letter reversal errors when first learning to read and write, even for letters whose reversed forms do not appear in normal print. However, the brain basis of such letter reversal in children learning to read is unknown. The present study compared the neuroanatomical correlates (via functional magnetic resonance imaging) and the electrophysiological correlates (via event-related potentials or ERPs) of this phenomenon in children, ages 5-12, relative to young adults. When viewing reversed letters relative to typically oriented letters, adults exhibited widespread occipital, parietal, and temporal lobe activations, including activation in the functionally localized visual word form area (VWFA) in left occipito-temporal cortex. Adults exhibited significantly greater activation than children in all of these regions; children only exhibited such activation in a limited frontal region. Similarly, on the P1 and N170 ERP components, adults exhibited significantly greater differences between typical and reversed letters than children, who failed to exhibit significant differences between typical and reversed letters. These findings indicate that adults distinguish typical and reversed letters in the early stages of specialized brain processing of print, but that children do not recognize this distinction during the early stages of processing. Specialized brain processes responsible for early stages of letter perception that distinguish between typical and reversed letters may develop slowly and remain immature even in older children who no longer produce letter reversals in their writing.

  3. Children's reasoning about disclosing adult transgressions: effects of maltreatment, child age, and adult identity.

    Science.gov (United States)

    Lyon, Thomas D; Ahern, Elizabeth C; Malloy, Lindsay C; Quas, Jodi A

    2010-01-01

    A total of two hundred ninety-nine 4- to 9-year-old maltreated and nonmaltreated children of comparable socioeconomic status and ethnicity judged whether children should or would disclose unspecified transgressions of adults (instigators) to other adults (recipients) in scenarios varying the identity of the instigator (stranger or parent), the identity of the recipient (parent, police, or teacher), and the severity of the transgression ("something really bad" or "something just a little bad"). Children endorsed more disclosure against stranger than parent instigators and less disclosure to teacher than parent and police recipients. The youngest maltreated children endorsed less disclosure than nonmaltreated children, but the opposite was true among the oldest children. Older maltreated children distinguished less than nonmaltreated children between parents and other types of instigators and recipients.

    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...

    2017-04-01

    One of the lawlike regularities of psychological science is that of developmental progression-an increase in sensorimotor, cognitive, and social functioning from childhood to adulthood. Here, we report a rare violation of this law, a developmental reversal in attention. In Experiment 1, 4- to 5-year-olds ( n = 34) and adults ( n = 35) performed a change-detection task that included externally cued and uncued shapes. Whereas the adults outperformed the children on the cued shapes, the children outperformed the adults on the uncued shapes. In Experiment 2, the same participants completed a visual search task, and their memory for search-relevant and search-irrelevant information was tested. The young children outperformed the adults with respect to search-irrelevant features. This demonstration of a paradoxical property of early attention deepens current understanding of the development of attention. It also has implications for understanding early learning and cognitive development more broadly.

    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.

Comparing corpus data with recent act-out and reading experiments involving Danish sentences with conflicting formal cues, we argue that context plays an important role in the resolution of semantic role distribution. Children and adults weigh morphosyntactic cues....... Previous experiments in a variety of languages have shown that sentences with conflicting formal cues are habitually miscomprehended by preschool children. For adults, they continue to be more difficult to read and comprehend, often being shallowly processed on the basis of heuristics. However, most...... differently, but we find a striking continuity in attention to context across development: when interpreting conflict clauses with object-before-subject structure, both children and adults systematically integrate intra- and extrasentential cues to assign semantic roles....

    Ungerer, J A; Horgan, B; Chaitow, J; Champion, G D

    1988-02-01

    A questionnaire survey of 363 children and young adults with juvenile arthritis was conducted to assess the relations among disease severity, psychosocial functioning, and adjustment in three age groups--primary school, high school, and young adult. Parents were surveyed separately to determine which characteristics of the ill child at different ages most significantly impact the well-being of the family. Indices of psychologic functioning and disease severity were associated with adjustment in the primary school and high school groups, whereas measures of social relationships were strongly associated with adjustment only in the high school group. Relations among measures of psychologic functioning, social relationships, disease severity, and adjustment in young adults were minimal. Level of disease severity was associated with the presence of financial concerns, emotional problems, and physical strain in parents of high school children and young adults. The results emphasize the importance of using a developmental model for understanding the adjustment of individuals with chronic juvenile arthritis and their families.

    2016-12-01

    Time perspective is a fundamental dimension of the psychological time construct, with a pervasive and powerful influence on human behavior. However, the developmental trajectory of time perspective across a human lifespan remains unclear. The current study aimed to portray the developmental trajectory of all dimensions of time perspectives from children to older adults in a large sample. A total of 1,901 individuals (aged 9-84 years) completed measures of time perspective. They were then divided into five age groups: children, teenagers, young adults, middle-aged adults, and older adults. Results suggested that each time perspective showed a unique developmental pattern across the lifespan. Moreover, perceived economic situation and education were related to some dimensions of time perspective.

    Full Text Available Michael Blomgren Department of Communication Sciences and Disorders, University of Utah, Salt Lake City, UT, USA Abstract: This paper provides a brief overview of stuttering followed by a synopsis of current approaches to treat stuttering in children and adults. Treatment is discussed in terms of multifactorial, operant, speech restructuring, and anxiolytic approaches. Multifactorial and operant treatments are designed for young children who stutter. Both of these approaches involve parent training and differ primarily in their focus on reducing demands on the child (multifactorial or in their use of response contingent stimulation (operant conditioning. Speech restructuring and anxiolytic approaches are used with adults who stutter. Speech restructuring approaches focus on the mechanics of speech production, and anxiolytic treatments tend to focus on the symptoms and social and vocational challenges of stuttering. The evidence base for these different approaches is outlined. Response contingent therapy (for children and speech restructuring therapy (for adults have the most robust empirical evidence base. Multifactorial treatments for children and stuttering management approaches for adults are popular but are based on theoretical models of stuttering; the evidence base is not robust and tends to be inferred from work in areas such as cognitive behavior therapy and desensitization. Comprehensive, or holistic, approaches to treating stuttering are also discussed. Comprehensive approaches for treating stuttering in adults address both improved speech fluency and stuttering management.

    2015-01-01

    Humans cross-culturally find infant faces both cute and highly likeable. Their so-called "baby schema" features have clear adaptive value by likely serving as an innate releasing mechanism that elicits caretaking behaviors from adults. However, we do not know whether experience with young children during social development might act to further facilitate this. Here we investigated the potential impact of having siblings on adult likeability judgments of children's faces. In this study, 73 adult men and women (40 with siblings and 33 without) were shown 148 different face pictures of young children (1 month to 6.5 years) and judged them for likeability. Results showed that both groups found faces of infants (sibling group showed a reduced liking for faces with increasing age, the sibling group found faces of all ages as equally likeable. Furthermore, for adults with siblings, the closer in age they were to their siblings, the stronger their likeability was for young children's faces. Our results are the first to show that having siblings can extend the influence of baby schema to children as well as infants.

    The consumption of whole grain foods is associated with many nutritional, health and weight control benefits. The present study assessed whole grain intake in France on the basis of a 7 d dietary survey in a representative sample of children, adolescents and adults (Comportements et Consommations Alimentaires en France 2010 survey). Special care was taken to identify and assess the intake of all whole grains. All foods consumed were considered, with no lower limit on whole grain content. For the majority of foods, details regarding the whole grain contents were obtained from brand information and quantitative nutrient declarations on food labels. Over half of the respondents reported never consuming any whole grain. In participants who did, consumption levels were very low (about 9·1 g/d in children and 14·4 g/d in adults). The main food sources of whole grains were breakfast cereals in children and adolescents and bread in adults. Consumers of whole grains had higher daily intakes of fibre and several vitamins and minerals than non-consumers. In adults but not in children, the OR for overweight/obesity decreased significantly as the level of whole grain consumption increased. Although a majority of French consumers comply with the national recommendation to consume a starchy food with each meal, they do so with minimal consumption of whole grain foods.

    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.

  13. Pediatric cardiac emergencies: Children are not small adults

    2011-01-01

    Full Text Available Compared with adults, cardiac emergencies are infrequent in children and clinical presentation is often quite variable. In adults, cardiac emergencies are most commonly related to complications of coronary artery disease; however, in pediatric cases, the coronaries are only rarely the underlying problem. Pediatric cardiac emergencies comprise a range of pathology including but not limited to undiagnosed congenital heart disease in the infant; complications of palliated congenital heart disease in children; arrhythmias related to underlying cardiac pathology in the teenager and acquired heart disease. The emergency room physician and pediatric intensivist will usually be the first and second lines of care for pediatric cardiac emergencies and thus it is imperative that they have knowledge of the diverse presentations of cardiac disease in order to increase the likelihood of delivering early appropriate therapy and referral. The objective of this review is to outline cardiac emergencies in the pediatric population and contrast the presentation with adults.

    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.

    To evaluate whether there are any differences in MR findings between the childhood and the adult moyamoya disease. We compared the brain MR findings in 22 children (13 boys and 9 girls, 2-18 years of age) who had moyamoya disease with 15 adult patients (7 men and 8 women, 19-55 years of age). The MR findings were classified as parenchymal-(infarctions and intracranial hemorrhages) and vascular abnormalities (intracranial vascular patency and moyamoya vessels). The difference in each of these MR findings was analyzed using Chi-square test and Fisher's exact test (two-tailed). Out of 22 children, two children with normal MR finding were excluded from the statistical analysis. Moyamoya diseases were diagnosed angiographically in all adult patients. In children, they were diagnosed by MR imaging, MR angiography(6), and/or conventional cerebral angiography(18). In children, cerebral infarctions were observed in 20 of 22 patients (91%) (cortex 86%, periventricular white matter/centrum semiovale 32%, basal ganglia 10%). In two patients, there was no parenchymal abnormality. Intracranial hemorrhages were not demonstrated in any patients. In adults, intracranial hemorrhages (intracerebral hematoma, intraventricular hemorrhage, alone or combined) were demonstrated in 10 of 15 patients(67%). Cerebral infarctions with or without intracranial hemorrhage were detected in 10 of 15 patients(67%) (cortex 40%, periventricular white matter/centrum semiovale 53%, basal ganglia 20%). The difference in parenchymal abnormalities between the childhood and the adult moyamoya disease was statistically significant ({rho} = 0.000164). There was no significant difference between the two groups with regard to the occlusive changes of the internal carotid and middle cerebral arteries or to moyamoya vessels ({rho} > 0.01). This study could prove the fact that the principal clinical symptoms in the childhood moyamoya disease were due to cerebral infarction and those in the adult cases were

    Van Cauter, Eve; Knutson, Kristen L

    2008-12-01

    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 indicate that chronic partial sleep loss may increase the risk of obesity and weight gain. The present article reviews laboratory evidence indicating that sleep curtailment in young adults results in a constellation of metabolic and endocrine alterations, including decreased glucose tolerance, decreased insulin sensitivity, elevated sympathovagal balance, increased evening concentrations of cortisol, increased levels of ghrelin, decreased levels of leptin, and increased hunger and appetite. We also review cross-sectional epidemiological studies associating short sleep with increased body mass index and prospective epidemiological studies that have shown an increased risk of weight gain and obesity in children and young adults who are short sleepers. Altogether, the evidence points to a possible role of decreased sleep duration in the current epidemic of obesity.

    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

  20. The patent ductus arteriosus in term infants, children, and adults.

    Schneider, Douglas J

    2012-04-01

    During fetal life, the ductus arteriosus is a normal and essential structure that connects the pulmonary artery to the distal aortic arch, permitting right ventricular ejection into the aorta. After birth, with commencement of pulmonary blood flow and a 2-ventricle circulation, a variety of physiological and biochemical signals normally result in complete closure of the ductus. Persistent patency of the ductus arteriosus may impair systemic cardiac output and result in deleterious effects on the cardiovascular system and lungs. Although surgery is still the treatment of choice for most premature infants with patent ductus arteriosus (PDA), transcatheter techniques have largely supplanted surgery for closure of PDA in children and adults. This article is a review of the PDA in term infants, children, and adults, with focus on the clinical manifestations and management.

    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.

    2016-12-01

    This study examined the possible intergenerational transmission of eating beliefs and intentions between 60 mothers and their adult children. Maternal restrictive feeding practices were correlated with mothers' own healthy eating attitudes and subjective norms, and with their adult children's subjective norms. Mothers' beliefs and intentions were correlated with their adult children. Adult children's intentions to eat healthily were predicted by their attitudes and perceived behavioural control, and also by their mothers' intentions and perceived behavioural control. Mothers' own beliefs and intentions may be involved in shaping their children's beliefs and intentions into adulthood but their child feeding practices may have less of an influence.

    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.

    2012-11-07

    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.

    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.

  14. Natural experience modulates the processing of older adult faces in young adults and 3-year-old children.

    Directory of Open Access Journals (Sweden)

    Valentina Proietti

    Full Text Available Just like other face dimensions, age influences the way faces are processed by adults as well as by children. However, it remains unclear under what conditions exactly such influence occurs at both ages, in that there is some mixed evidence concerning the presence of a systematic processing advantage for peer faces (own-age bias across the lifespan. Inconsistency in the results may stem from the fact that the individual's face representation adapts to represent the most predominant age traits of the faces present in the environment, which is reflective of the individual's specific living conditions and social experience. In the current study we investigated the processing of younger and older adult faces in two groups of adults (Experiment 1 and two groups of 3-year-old children (Experiment 2 who accumulated different amounts of experience with elderly people. Contact with elderly adults influenced the extent to which both adult and child participants showed greater discrimination abilities and stronger sensitivity to configural/featural cues in younger versus older adult faces, as measured by the size of the inversion effect. In children, the size of the inversion effect for older adult faces was also significantly correlated with the amount of contact with elderly people. These results show that, in both adults and children, visual experience with older adult faces can tune perceptual processing strategies to the point of abolishing the discrimination disadvantage that participants typically manifest for those faces in comparison to younger adult faces.

  17. The need to differentiate between adults and children when treating severe asthma.

    Science.gov (United States)

    Fainardi, Valentina; Saglani, Sejal

    2015-08-01

    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.

  18. Walking to the beat of their own drum: how children and adults meet timing constraints.

    Directory of Open Access Journals (Sweden)

    Simone V Gill

    Full Text Available Walking requires adapting to meet task constraints. Between 5- and 7-years old, children's walking approximates adult walking without constraints. To examine how children and adults adapt to meet timing constraints, 57 5- to 7-year olds and 20 adults walked to slow and fast audio metronome paces. Both children and adults modified their walking. However, at the slow pace, children had more trouble matching the metronome compared to adults. The youngest children's walking patterns deviated most from the slow metronome pace, and practice improved their performance. Five-year olds were the only group that did not display carryover effects to the metronome paces. Findings are discussed in relation to what contributes to the development of adaptation in children.

  19. Urinary growth hormone excretion in 657 healthy children and adults

    DEFF Research Database (Denmark)

    Main, K; Philips, M; Jørgensen, M

    1991-01-01

    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...... in nanograms per gram creatinine did not diminish the observed variation and blunted the pubertal increase in u-GH excretion. In conclusion, (1) u-GH excretion depends significantly on age, sex and pubertal maturation as does the day/night ratio of u-GH excretion. (2) The interindividual variation in u...

    Dalrymple, Kirsten A; Palermo, Romina

    2016-01-01

    Developmental prosopagnosia (DP) is a neurodevelopmental condition characterized by severe face identity recognition problems that results from a failure to develop the mechanisms necessary for adequate face processing (Duchaine BC, Nakayama K. Developmental prosopagnosia: a window to content-specific face processing. Curr Opin Neurobiol 2006, 16:166-173.). It occurs in children and adults with normal visual acuity, and without intellectual impairments or known brain injuries. Given the importance of face recognition in daily life, and the detrimental effects of impaired face recognition, DP is an important area of study. Yet conventions for classifying individuals as DP for research purposes are poorly defined. In this focus paper, we discuss: (1) criteria for an operational definition of DP; 2) tests of face recognition and conventions for classifying individuals as DP; and 3) important considerations regarding common associations and dissociations, and cognitive heterogeneity in DP. We also highlight issues unique to studying DP in children, a relatively new endeavor that is proving to be an important complement to the work with adults. Ultimately, we hope to identify challenges researchers face when studying DP, and offer guidelines for others to consider when embarking on their own research pursuits on the topic.

    2007-08-01

    Balance control during gait initiation was studied using center of pressure (CoP) data from force plate measurements. Twenty-four participants were divided into four age groups: (1) 2-3 years, (2) 4-5 years, (3) 7-8 years, and (4) adults. Movement in the antero-posterior (CoPy) direction during the initial step was tau-G analyzed, investigating the hypothesis that tau of the CoPy motion-gap (tau(CoPy)), i.e., the time it will take to close the gap at its current closure rate, is tau-coupled onto an intrinsic tau-G guide (tau(G)), by maintaining the relation tau(CoPy )= Ktau(G), for a constant K. Mean percentage of tau-guidance for all groups was >/=99%, resulting in all r(2) exceeding 0.95, justifying an investigation of the regression slope as an estimate of the coupling constant K in the tau-coupling equation. Mean K values decreased significantly with age and were for 2- to 3-year-olds 0.56, for 4- to 5-year-olds 0.50, for 7- to 8-year-olds 0.47, and for adults 0.41. Therefore, the control of dynamic balance develops from the youngest children colliding with the boundaries of the base of support (K > 0.5) to the older children and adults making touch contact (K

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

    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

    The aim was to develop sedentary (sitting/lying) thresholds from hip and wrist worn raw tri-axial acceleration data from the ActiGraph and GENEActiv, and to examine the agreement between free-living time spent below these thresholds with sedentary time estimated by the activPAL. Sixty children and adults wore an ActiGraph and GENEActiv on the hip and wrist while performing six structured activities, before wearing the monitors, in addition to an activPAL, for 24 h. Receiver operating characteristic (ROC) curves were used to determine sedentary thresholds based on activities in the laboratory. Agreement between developed sedentary thresholds during free-living and activPAL were assessed by Bland-Altman plots and by calculating sensitivity and specificity. Using laboratory data and ROC-curves showed similar classification accuracy for wrist and hip thresholds (Area under the curve = 0.84-0.92). Greatest sensitivity (97-98%) and specificity (74-78%) were observed for the wrist thresholds, with no large differences between brands. During free-living, Bland-Altman plots showed large mean individual biases and 95% limits of agreement compared with activPAL, with smallest difference for the ActiGraph wrist threshold in children (+30 min, P = 0.3). Sensitivity and specificity for the developed thresholds during free-living were low for both age groups and for wrist (Sensitivity, 68-88%, Specificity, 46-59%) and hip placements (Sensitivity, 89-97%, Specificity, 26-34%). Laboratory derived sedentary thresholds generally overestimate free-living sedentary time compared with activPAL. Wrist thresholds appear to perform better than hip thresholds for estimating free-living sedentary time in children and adults relative to activPAL, however, specificity for all the developed thresholds are low.

    Cross-cultural comparisons provide critical insight into variation in reasoning about intelligence. In two studies, the authors used a novel methodology based on multivocal ethnography to assess the role of conformity in U.S. and Ni-Vanuatu adults' judgments of children's intelligence and, as a comparison trait, good behavior. In Study 1, there were cultural differences in the impact of conformity on U.S. and Ni-Vanuatu adults' judgments of children's intelligence and good behavior. When evaluating U.S. children only, U.S. adults were less likely to endorse high conformity children as intelligent, often citing creativity as a justification for their judgments. In contrast, Ni-Vanuatu adults were more likely to endorse Ni-Vanuatu high conformity children as intelligent. Ni-Vanuatu adults were also more likely to endorse high conformity children as well-behaved than U.S. adults. In Study 2, there were no effects of socioeconomic status on U.S. adults' evaluations of conformity. U.S. adults were less likely to endorse high conformity children as intelligent than Ni-Vanuatu adults. Taken together, the data demonstrate that beliefs about the relations between intelligence, conformity, and creativity vary within and across cultures. (PsycINFO Database Record

  1. The left perceptual bias for adult and infant faces in adults and 5-year-old children: face age matters.

    2015-01-01

    A large number of studies have shown that adults rely more heavily on information conveyed by the left side of the face in judging emotional state, gender and identity. This phenomenon, called left perceptual bias (LPB), suggests a right hemisphere lateralization of face processing mechanisms. Although specialization of neural mechanisms for processing over-experienced face categories begins during the first year of life, little is known about the developmental trajectory of the LPB and whether or when the bias becomes selective for specific face categories as a result of experience. To address these questions we tested adults (Experiment 1) and 5-year-old children (Experiment 2) with null or limited experience with infants in an identity matching-to-sample task with chimeric adult and infant faces, for which both adults and children have been shown to manifest differential processing abilities. Results showed that 5-year-olds manifest a leftward bias selective for adult faces, and the magnitude of the bias is larger for adult compared to infant faces in adults. This evidence is in line with earlier demonstrations of a perceptual processing advantage for adult faces in adults and children and points to the role of experience in shaping neurocognitive specialization for face processing.

  2. Audibility-based predictions of speech recognition for children and adults with normal hearing.

    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.

    Systemic sclerosis (SSc) presents a great deal of variability in the extent and severity of skin and internal organ involvement. The diagnostic and prognostic significance of autoantibodies in SSc is undisputed and the patient's autoantibody profile represents a fundamental tool for clinicians. Scleroderma is a rare condition in children. Unlike adults, localized scleroderma is more frequent than the systemic sclerosis, nevertheless it represents a disabling condition. In both conditions, no validated outcome measures and proven effective treatment is available to date.Raynaud's phenomenon (RP) is one the most common and significant clinical symptoms of SSc and therefore in patients with RP a capillaroscopic analysis should be carried out as soon as possible. The actual and select advantage of the early nailfold videocapillaroscopic (NVC) analysis is to distinguish between the primary RP and the secondary RP and to allow the early detection of SSc.

    Serum levels of the immunoglobulins: IgG, IgA and IgM were determined by the single radial immunodiffusion technique of Mancini in a total of 122 apparently healthy subjects consisting of 43 children (20 males; 23 females) aged 5-12 years and 79 adults (39 males; 40 females) aged 18-65 years resident in Port Harcourt, southeastern Nigeria. The effects of age and sex on the serum levels of the various immunoglobulin types were also determined. The mean values and ranges for the various immunoglobulin types are presented for both children and adults. Although, female children were found to have significantly lower mean values of IgA compared to male children (p0.05). However, female adults had significantly higher mean values of IgG and significantly lower mean values of IgA compared to male adults (pimmunoglobulin between adults and children. The present study reports mean values of the various types of immunoglobulin in apparently healthy children and adults resident in Port Harcourt, southeastern Nigeria. Significant gender differences were observed for some of the immunoglobulin types only amongst adults. Our results suggest that these gender differences amongst adults were apparently a gradual build-up from childhood. The results also confirm suggestions that levels of some immunoglobulin types seen amongst African adults may have possibly been attained during childhood. Our study could be of value since previous reports in this regard have been relatively scanty especially in this part of Nigeria.

    Giardia duodenalis is considered the most common intestinal parasite in humans worldwide. Children are especially affected, with more severe consequences than adults. The present study was designed to determine the distribution of assemblages A and B Giardia infection in children and adults, with the use of light microscopy and polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) as diagnostic procedures, and to investigate its associations with clinical and epidemiological data collected from children and adult groups. This cross-sectional study was conducted from October 2012 to October 2013 by collecting fecal samples from 200 children and 200 adults complaining of diarrhea. Samples were subjected to parasitological examination by direct wet smear and formol-ether methods. Genotyping of G. doudenalis samples was conducted by PCR-RFLP analysis. Giardia duodenalis infection caused by assemblages A and B was identified in 60 samples, 34 from children and 26 from adults. Assemblage B was detected in 38 patients (63.34%), and assemblage A was detected in 22 patients (36.66%). Assemblage A was significantly more frequent in children with age range 2-8 yr, and assemblage B was higher in children with age range 6-16 yr old. Diarrhea frequency/day and recurrences per month affected patients infected with assemblage A (P value Giardia assemblages A and B were identified in children and adults, assemblage A infected younger children more frequently and was more closely related to severe clinical manifestations than assemblage B.

    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.

    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.

    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.

    2014-01-01

    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 analyze randomization 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 toward the left side of representational space or lower numbers).

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.

    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.

    Full Text Available This study was undertaken to determine the seroprevalence of H.pylori in asymptomatic children and compare it with that seen in the asymptomatic adult population from south India. One hundred and five children and one hundred adults admitted to the wards for conditions other than gastrointestinal disorders were included for this study. H.pylori status was determined by ELISA for IgG. The prevalence of H.pylori in children of various ages varied from 44% to 46% with an overall prevalence of H.pylori in children of 45%. 67% of adults were infected with H.pylori which was significantly higher than children (P = 0.002. The prevalence of H.pylori increased markedly with age with the maximum colonization (74% occurring in young adults (16-30 years. The antibody levels too followed a similar pattern. In conclusion, it was seen that almost half the children in south India acquire H.pylori infection early in life which increases slowly and steadily with a peak prevalence in the young adults. Gender does not affect the prevalence in children and adults. As age advances further there is a slight decline in the prevalence of H.pylori infection. The immune response reflected by the levels of the antibody levels also follows the same pattern.

  17. 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

  1. Adults' representations of the Earth: implications for children's acquisition of scientific concepts.

    Science.gov (United States)

    Nobes, Gavin; Panagiotaki, Georgia

    2007-11-01

    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.

  2. 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.

    The present study examined general and romantic attachment and parenting students received in their families of origin among 401 college students who resided with an alcohol-abusing parent prior to age 16 years as compared to those who did not reside with alcohol-abusing parents. Participants completed the Children's Report of Parent Behavior Instrument [Schludermann, E. and Schludermann, S. (1970). Children's Report of Parent Behavior Inventory (CRPBI). Canada: University of Manitoba], Experiences in Close Relationships--Revised [Fraley, R. C., Waller, N. G., and Brennan, K. G. (2000). An item response theory analysis of self-report measures of adult attachment. Journal of Personality and Social Psychology, 78, 350-365], Relationship Scale Questionnaire [Griffin, D. W. and Bartholomew, K. (1994). Models of the self and other: Fundamental dimensions underlying measures of adult attachment. Journal of Personality and Social Psychology, 67, 430-445], and the Children of Alcoholics Screening Test [Jones, J. W. (1983). The Children of Alcoholics Screening Test: Test manual. Chicago: Camelot]. Young adults who met criteria for ACOAs reported more anxious and avoidant behavior in romantic relationships and a more fearful style of general adult attachment. Parenting behavior in one's family of origin predicted anxious behavior in romantic relationships and a fearful overall style of attachment, whereas being an ACOA and parenting in one's family of origin predicted avoidant behavior in romantic relationships.

    Introduction Neural response telemetry (NRT) is a method of capturing the action potential of the distal portion of the auditory nerve in cochlear implant (CI) users, using the CI itself to elicit and record the answers. In addition, it can also measure the recovery function of the auditory nerve (REC), that is, the refractory properties of the nerve. It is not clear in the literature whether the responses from adults are the same as those from children. Objective To compare the results of NRT and REC between adults and children undergoing CI surgery. Methods Cross-sectional, descriptive, and retrospective study of the results of NRT and REC for patients undergoing IC at our service. The NRT is assessed by the level of amplitude (microvolts) and REC as a function of three parameters: A (saturation level, in microvolts), t0 (absolute refractory period, in seconds), and tau (curve of the model function), measured in three electrodes (apical, medial, and basal). Results Fifty-two patients were evaluated with intraoperative NRT (26 adults and 26 children), and 24 with REC (12 adults and 12 children). No statistically significant difference was found between intraoperative responses of adults and children for NRT or for REC's three parameters, except for parameter A of the basal electrode. Conclusion The results of intraoperative NRT and REC were not different between adults and children, except for parameter A of the basal electrode. PMID:25992145

  7. The neurodevelopmental differences of increasing verbal working memory demand in children and adults

    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.

    2016-06-01

    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.

    To examine the development of recognition memory in primary-school children, 36 healthy younger children (8-9 years old) and 36 healthy older children (11-12 years old) participated in an ERP study with an extended continuous face recognition task (Study 1). Each face of a series of 30 faces was shown randomly six times interspersed with distracter faces. The children were required to make old vs. new decisions. Older children responded faster than younger children, but younger children exhibited a steeper decrease in latencies across the five repetitions. Older children exhibited better accuracy for new faces, but there were no age differences in recognition accuracy for repeated faces. For the N2, N400 and late positive complex (LPC), we analyzed the old/new effects (repetition 1 vs. new presentation) and the extended repetition effects (repetitions 1 through 5). Compared to older children, younger children exhibited larger frontocentral N2 and N400 old/new effects. For extended face repetitions, negativity of the N2 and N400 decreased in a linear fashion in both age groups. For the LPC, an ERP component thought to reflect recollection, no significant old/new or extended repetition effects were found. Employing the same face recognition paradigm in 20 adults (Study 2), we found a significant N400 old/new effect at lateral frontal sites and a significant LPC repetition effect at parietal sites, with LPC amplitudes increasing linearly with the number of repetitions. This study clearly demonstrates differential developmental courses for the N400 and LPC pertaining to recognition memory for faces. It is concluded that face recognition in children is mediated by early and probably more automatic than conscious recognition processes. In adults, the LPC extended repetition effect indicates that adult face recognition memory is related to a conscious and graded recollection process rather than to an automatic recognition process.

    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

    The perisylvian region of the human cortex is known to play a major role in language processing. Especially the superior temporal cortex (STC) and the inferior frontal cortex (IFC) have been investigated with respect to their particular involvement in language comprehension. In the present research, the timing of recruitment of these language-related brain areas in both hemispheres was examined as a function of age using functional imaging data of 6-year-old children and adults with a special focus on blood oxygenation level dependent (BOLD) response time courses. The results show that children's activation time courses differ from that of adults. First, children show an overall later peak of BOLD responses. Second, children's IFC responds much later than their STC, while in adults the difference between both regions is less pronounced. Within the STC, both groups show similar regionally U-shaped activation patterns with fastest peaks in voxels at the STC's mid-portion around Heschl's gyrus and longer latencies in anterior and posterior directions, suggesting a coarsely similar information flow in adults and children in the temporal region. Finally, children in contrast to adults, display a temporal primacy of right over left hemispheric activation. The observed overall latency differences between children and adults are in line with the assumption of ongoing maturation in perisylvian brain regions and the connections between them. A functional perspective on BOLD timing argues for a developmental change from higher processing costs in children compared to adults due to slower and less automatic language processes, in particular those located in the IFC. The observed hemispheric differences are discussed in the context of developmental models assuming a high reliance on right-hemisphere-based suprasegmental information processing during language comprehension in childhood.

    Background: Data on the physical strength capabilities are essential for designing 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 lateral 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. PMID:26000246

    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.

    Introduction The acute abdomen is the main term for an at first unclear emergency situation of the abdominal cavity. The acute abdomen belongs to the three most important reasons for the admission of patients into the emergency room. Further, this illness ranks 40% of all consultations in the ambulant care sector. The acute abdomen requires an early and direct diagnosis because of its potential of having a life threatening differential diagnosis. This HTA report aimed to assess the ultrasound diagnosis of the acute abdomen considering children and adults. This will be done from a medical and economic perspective. The differential diagnosis respectively the cause of the acute abdomen binds high direct treatment costs, especially in the stationary sector. Ultrasound diagnosis is a procedure that plays a big part in the differential diagnosis process and it is widely used in practise. Other research methods of diagnosing acute abdominal illness are: clinical examinations with inspection and palpation, surgical exploration and laparocopy as well as computer tomography and x-ray examination. Objectives The main objective of this HTA report is to assess what significance sonography should have within the examination strategy of the acute abdomen from the medical and economical view. Second, this HTA report will evaluate under which circumstances the ultrasonographic diagnosis of the acute abdomen, considering medical and economical quality classifications, is the alternative of choice to comparable diagnostic measures. Methods The target population this HTA report is aimed at are children and adults with acute abdomen or embedded differential diagnosis. A systematic literature search was conducted covering all relevant medical and HTA-databases. Furthermore, handsearch was conducted inside of the known data bases of HTA-institutions as well as from medical and economical journals. The following databases were searched in cooperation with DIMDI to identify relevant

  1. Adults' Insensitivity to Developmental Changes in Children's Ability to Report When and How Many Times Abuse Occurred.

    In legal settings, children are frequently asked to provide temporal information about alleged abuse, such as when it occurred and how often. Although there is a sizeable body of work in the literature regarding children's ability to provide such information, virtually nothing is known about how adults evaluate the veracity of that information. This omission is especially noteworthy given that adults' evaluations are critical to the progression and outcome of legal cases. We examined adults' perceptions of children's reports of temporal details regarding alleged sexual abuse. We varied both children's age (6 vs. 11 years) and how certain children were when providing such details to assess whether adults were sensitive to changes in how children of different ages typically talk about temporal information. With regard to credibility, adults were insensitive to children's age, perceiving younger and older children who reported temporal details with confidence as more credible than those who reported information tentatively. Normative developmental trends, however, would suggest that, with age, children are often tentative when reporting true temporal details. With regard to perceptions of children's accuracy in reporting temporal information, adults found younger children who were confident to be the most accurate. Regarding guilt judgments, adults rated defendants as having a higher degree of guilt when children were confident in reporting temporal details. The findings have implications for juror decision-making in cases of alleged sexual abuse in which children report when or how often abuse occurred. Copyright © 2016 John Wiley & Sons, Ltd.

  2. The Influence of Social Category and Reciprocity on Adults' and Children's Altruistic Behavior

    Full Text Available Evolutionary theories of altruism have suggested that reciprocal exchanges and ingroup favoritism have been important strategies leading to the evolution of altruistic behavior among strangers. This study investigates whether minimal information about an interaction partner's membership in a trivial social group affects the allocations of adults and children in dictator game, reciprocity in a sequential prisoner's dilemma, and altruistic punishment in a third-party punishment game. In all, 155 adults and 157 students from second and sixth grade played these three economic games in either an ingroup, outgroup, or neutral condition. Adults and sixth-grade children allocated more to ingroup than to outgroup receivers in the dictator game, and adults punished ingroup non-cooperators more in the third-party punishment game than outgroup non-cooperators. When additional information about the other player's past behavior was presented, adults reciprocated equally with ingroup, outgroup, and neutral players, whereas children from sixth grade reciprocated more with ingroup and neutral than with outgroup players. Overall, the results of this study support the importance of group membership and reciprocity for adults' and older elementary school children's altruistic behavior. For younger elementary school children, however, reciprocity and group membership do not serve as salient social information that influence their altruistic behavior.

    Most research on human fear conditioning and its generalization has focused on adults whereas only little is known about these processes in children. Direct comparisons between child and adult populations are needed to determine developmental risk markers of fear and anxiety. We compared 267 children and 285 adults in a differential fear conditioning paradigm and generalization test. Skin conductance responses (SCR) and ratings of valence and arousal were obtained to indicate fear learning. Both groups displayed robust and similar differential conditioning on subjective and physiological levels. However, children showed heightened fear generalization compared to adults as indexed by higher arousal ratings and SCR to the generalization stimuli. Results indicate overgeneralization of conditioned fear as a developmental correlate of fear learning. The developmental change from a shallow to a steeper generalization gradient is likely related to the maturation of brain structures that modulate efficient discrimination between danger and (ambiguous) safety cues.

  5. 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.

    Comparison of brain function between children and adults with autism provides an understanding of the effects of the disorder and associated maturational differences on language processing. Functional imaging (functional magnetic resonance imaging) was used to examine brain activation and cortical synchronization during the processing of literal and ironic texts in 15 children with autism, 14 children with typical development, 13 adults with autism, and 12 adult controls. Both the children and adults with autism had lower functional connectivity (synchronization of brain activity among activated areas) than their age and ability comparison group in the left hemisphere language network during irony processing, and neither autism group had an increase in functional connectivity in response to increased task demands. Activation differences for the literal and irony conditions occurred in key language-processing regions (left middle temporal, left pars triangularis, left pars opercularis, left medial frontal, and right middle temporal). The children and adults with autism differed from each other in the use of some brain regions during the irony task, with the adults with autism having activation levels similar to those of the control groups. Overall, the children and adults with autism differed from the adult and child controls in (a) the degree of network coordination, (b) the distribution of the workload among member nodes, and (3) the dynamic recruitment of regions in response to text content. Moreover, the differences between the two autism age groups may be indicative of positive changes in the neural function related to language processing associated with maturation and/or educational experience.

    The aim of this experiment is to compare sensory specific satiety (SSS) and sensory specific desire to eat (SSD), which can be described as general wanting for certain taste categories and go beyond specific foods, in children and adults and their impact on subsequent food choices. Eighty-seven children (10.3 ± 0.6 years) and 49 adults (31.0 ± 2.0 years) participated in the study. Sweet pear banana yoghurt was used as the food eaten to satiation, and test foods representing sweet, salty, sour, bitter, "fatty", and "spicy" flavors were also evaluated (foods not eaten). At baseline and post meal participants evaluated hunger, satiation, liking, and wanting for test foods and yoghurt, and desires on a 150 mm visual analogue score (VAS) scale. The yoghurt was eaten until a state of "comfortable satiation" was reached. Results showed that SSS and SSD were expressed differently in children and adults. In children, SSS was primarily product specific and bound to the yoghurt, whereas in adults SSS was transferred to the uneaten foods sharing sensory characteristics with the yoghurt (namely sweet, sour and "fatty"), which all decreased in their liking post meal. Similar differences were found for SSD. We conclude that children and adults differ in their expression of SSS and SSD, and this might have implications for planning meal compositions.

    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.

    The present study concerned the perceptual processing of complex auditory stimuli in 10 children (M age = 8.1) as compared to 10 young adults (M age = 19.3) and 10 older adult subjects (M age = 54.2). The auditory stimulus used was 10 sec. of rock music (Led Zeppelin, 1969). All three groups provided numerical responses to nine intensities of the rock music stimulus (10, 20, 30, 40, 50, 60, 70, 80, 90 dB above threshold). Analysis showed that the children reported a wider range of numerical responses than both adult groups. The mean numerical responses for the children ranged from .54 to 54.24. For the young adults the range was .76 to 11.37, and for the older subjects it was 1.6 to 23.31. Results suggest that the children were not bound by the same set of rules as the adults with regard to magnitude estimation scaling of the loudness of the rock music stimulus. Their internal scaling mechanisms appeared to be more flexible and broader based than those of the adults who participated in this study.

    The outcome of 38 median and ulnar nerve injuries at the wrist in 15 adults and 15 children were studied with a follow-up of at least 1 year. Each patient was assessed clinically and with nerve conduction studies. The results confirm a markedly superior sensory recovery in children. However the children had persistent motor deficiencies. This difference in the clinical results of adults and children was not reflected in the nerve conduction results which were similar in both groups.

  13. Cognitive Cues are More Compelling than Facial Cues in Determining Adults' Reactions towards Young Children

    Full Text Available Previous research has demonstrated the significant influence that both children's facial features (Lorenz, 1943 and children's cognitive expressions (Bjorklund, Hernández Blasi, and Periss, 2010 have on adults' perception of young children. However, until now, these two types of cues have been studied independently. The present study contrasted these two types of cues simultaneously in a group of college students. To this purpose, we designed five experimental conditions (Consistent, Inconsistent, Mature-Face, Immature-Face, and Faces-Only in which we varied the presentation of a series of mature and immature vignettes (including two previously studied types of thinking: natural thinking and supernatural thinking associated with a series of more mature and less mature children's faces. Performance in these conditions was contrasted with data from a Vignettes-Only condition taken from Bjorklund et al. (2010. Results indicated that cognitive cues were more powerful than facial cues in determining adults' perceptions of young children. From an evolutionary developmental perspective, we suggest that facial cues are more relevant to adults during infancy than during the preschool period, when, with the development of spoken language, the verbalized expressions of children's thoughts become the principal cues influencing adults' perceptions, with facial cues playing a more secondary role.

    Central nervous system primitive neuroectodermal tumors (CNS PNETs) predominantly occur in children and rarely in adults. Because of the rarity of this tumor, its outcomes and prognostic variables are not well characterized. The purpose of this study was to evaluate clinical outcomes and prognostic factors for children and adults with CNS PNET. The records of 26 patients (11 children and 15 adults) with CNS PNET from 1991 to 2011 were reviewed retrospectively. Disease-free survival (DFS) and overall survival (OS) were estimated with the Kaplan-Meier method, and relevant prognostic factors were analyzed. For the cohort, both the 5-year DFS and the OS were 46 %. For pediatric patients, the 5-year DFS was 78 %; for adult patients, it was 22 % (P = 0.004). Five-year OS for the pediatric and adult patients was 67 and 33 %, respectively (P = 0.07). With bivariate analysis including chemotherapy regimen (high dose vs. standard vs. nonstandard) or risk stratification (standard vs. high) and age, the increased risk of disease recurrence in adults persisted. A nonsignificant tendency toward poorer OS in adult patients relative to pediatric patients also persisted. High-dose chemotherapy with stem cell rescue was associated with a statistically significant improvement in OS and a tendency toward improved DFS, although the findings were mitigated when the effect of age was considered. Local recurrence was the primary pattern of treatment failure in both adults and children. Our results suggest that adult patients with CNS PNETs have inferior outcomes relative to the pediatric cohort. Further research is needed to improve outcomes for CNS PNET in populations of all ages.

    2013-01-01

    Background Keeping older adults healthy and active is an emerging challenge of an aging society. Despite the importance of personal relationships to their health and well-being, changes in family structure have resulted in a lower frequency of intergenerational interactions. Limited studies have been conducted to compare different interaction style of intergenerational interaction. The present study aimed to compare the changes in visual attention, facial expression, engagement/behaviour, and intergenerational conversation in older adults brought about by a performance-based intergenerational (IG) program and a social-oriented IG program to determine a desirable interaction style for older adults. Methods The subjects of this study were 25 older adults who participated in intergenerational programs with preschool children aged 5 to 6 years at an adult day care centre in Tokyo. We used time sampling to perform a structured observation study. The 25 older participants of intergenerational programs were divided into two groups based on their interaction style: performance-based IG program (children sing songs and dance) and social-oriented IG program (older adults and children play games together). Based on the 5-minute video observation, we compared changes in visual attention, facial expression, engagement/behaviour, and intergenerational conversation between the performance-based and social-oriented IG programs. Results Constructive behaviour and intergenerational conversation were significantly higher in the social-oriented IG programming group than the performance-based IG programming group (pprogramming group than the performance-based IG programming (pprogramming group than the social-oriented IG programming group (pIntergenerational programs with preschool children brought smiles and conversation to older adults.

    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.

    Adults' evaluations of children's reports can determine whether legal proceedings are undertaken and whether they ultimately lead to justice. The current study involved 92 undergraduates and 35 laypersons who viewed and evaluated videotaped interviews of 3- and 5-year-olds providing true or false memory reports. The children's reports fell into the following categories based on a 2 (event type: true vs. false) × 2 (child report: assent vs. denial) factorial design: accurate reports, false reports, accurate denials, and false denials. Results revealed that adults were generally better able to correctly judge accurate reports, accurate denials, and false reports compared with false denials: For false denials, adults were, on average, "confident" that the event had not occurred, even though the event had in fact been experienced. Participant age predicted performance. These findings underscore the greater difficulty adults have in evaluating young children's false denials compared with other types of reports. Implications for law-related situations in which adults are called upon to evaluate children's statements are discussed.

    It has been found that humans are able to distinguish colours without luminance cues by about 2-4 months of age and that sensitivity to colour difference develops during childhood, reaching a peak around adolescence. This prolonged period of maturation is reflected by improvements in psychophysical threshold measures and by the VEP characteristics of morphology, latency and amplitude. An intra-individual comparison of VEP and psychophysical responses to isoluminant colour stimuli has not been made in children, however, and this was the aim of the present study. VEPs were recorded from 49 subjects, children (age range: 4.8-12.6 years) and adults (age range: 25.7-33.2 years). Psychophysical and VEP thresholds were both measured in 40 of those subjects. Nominally isoluminant chromatic (L-M) sinewave gratings were presented in onset-offset mode and identical stimuli were used for psychophysical and VEP recordings to allow comparison. In agreement with previous reports, morphology of the transient VEP in response to this stimulus differed considerably between children and adults. There was a significant difference between psychophysical and VEP thresholds in children, but not in adults. Our findings support and expand on previous work on maturation of the L-M chromatic pathway and indicate a larger discrepancy between VEP and psychophysical chromatic thresholds in children than in adults.

    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.

    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.

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.

    Recent research has shown that participation in migrant labor markets has led to substantial increases in income for families in rural China. This article addresses the question of how participation is affected by elderly parent health. We find that younger adults are less likely to work as migrants when a parent is ill. Poor health of an elderly parent has less impact on the probability of employment as a migrant when an adult child has siblings who may be available to provide care. We also highlight the potential importance of including information on nonresident family members when studying how parent illness and elder care requirements influence the labor supply decisions of adult children.

    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

    The purpose of this study is to characterize the muscle architecture of children and adults using magnetic resonance elastography and ultrasound techniques. Five children (8-12 yr) and seven adults (24-58 yr) underwent both tests on the vastus medialis muscle at relaxed and contracted (10% and 20% of MVC) states. Longitudinal ultrasonic images were performed in the same area as the phase image showing the shear wave's propagation. Two geometrical parameters were defined: the wave angle (α(_MRE)) corresponding to the shear wave propagation and the fascicule angle (α(_US)) tracking the path of fascicles. Moreover, shear modulus was measured at different localizations within the muscle and in the subcutaneous adipose tissue. The association of both techniques demonstrates that the shear wave propagation follows the muscle fascicles path, reflecting the internal muscle architecture. At rest, ultrasound images revealed waves propagating parallel to the children fascicle while adults showed oblique waves corresponding to already oriented (α(_US)=15.4±2.54°) muscle fascicles. In contraction, the waves' propagation were in an oblique direction for children (α(_US_10%MVC)=10.6±2.27°, α(_US_20%MVC)=10.2±2.29°) as well as adults (α(_US_10%MVC)=15.4±2.54°, α(_US_20%MVC)=17.2±2.44°). A stiffness variation (1 kPa) was found between the upper and lower parts of the adult VM muscle and a lower stiffness (1.85±0.17 kPa) was measured in the subcutaneous adipose tissue. This study demonstrates the feasibility of the MRE technique to provide geometrical insights from the children and adults muscles and to characterize different physiological media.

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

    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.

    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.

    According to the literature, simple shapes induce emotional responses. Current evaluations suggest that humans consider angular shapes as “bad” and curvilinear forms as “good,” but no behavioral data are available to support this hypothesis. Atypical development, such as autism spectrum disorder (ASD), could modify humans’ perception of visual stimuli and thereby their emotional effect. This study assessed the effects of simple stimuli (i.e., jagged edges shape, disk, star, spiral, eye-like shape, and head character) on the emotional responses of different groups of humans. First, we assessed the effects of a looming movement on neurotypical adults’ emotional responses. Second, we assessed the effects of atypical development on emotional responses by comparing the reactions of neurotypical children and of children with ASD. We used different methodological approaches: self-evaluation through questionnaires and direct observation of participants’ behavior. We found that (1) neurotypical adults tended to perceive looming stimuli negatively as they associated more negative feelings with them although few behavioral responses could be evidenced and (2) the emotional responses of neurotypical children and of children with ASD differed significantly. Neurotypical children perceived the spiral stimulus positively, i.e., a curvilinear shape, whereas children with ASD perceived the jagged edges stimulus positively, i.e., an angular shape. Although neurotypical children and children with ASD presented some behavioral responses in common, children with ASD smiled and vocalized more than did neurotypical children during stimuli presentations. We discuss our results in relation to the literature on humans’ perception of simple shapes and we stress the importance of studying behavioral components for visual cognition research.

    In a sample of 3- and 5-yr.-old children, smoking in the home was found to be significantly and inversely related to IQ. Children of normal birth weight and without neurological impairment had been enrolled in a longitudinal study of child development. Analyses were conducted with sex, ethnicity, socioeconomic status, educational stimulation in the home, day care, and mother's intelligence controlled. Significant results were obtained for scores on the Peabody Picture Vocabulary Test-Revised at age three years and on the major Stanford-Binet Fourth Edition scales at ages three and five years. All effects were for the mother, not the father, smoking in the home.

    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.

    Purpose 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. Methods 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). Results 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. Conclusions 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

  6. Education-Related Parameters in High Myopia: Adults versus School Children.

    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.

    2015-01-01

    INTRODUCTION: Tumors of the parotid gland in children are rare and very little data has been published regarding the incidence of these tumors. We present a nationwide survey on this topic. METHODS: Data regarding benign and malignant tumors in the parotid gland in children from January 1st, 1990...... and one with mucoepidermoid carcinoma. Both patients had perineural invasion and involved resection margins at presentation. The incidence was 0.12 and 0.53 per 100,000 children of the malignant and benign tumors, respectively. CONCLUSION: Pleomorphic adenomas were the predominant neoplasm in the parotid...... gland in children. The most frequent of the malignant tumors was the acinic cell carcinoma, which is in contrast to previous studies. The proportion of malignant-to-benign parotid gland tumors is in contrast to earlier study reports not higher in children than in adults....

    Pérez-Escamilla, Rafael; Obbagy, Julie E; Altman, Jean M; Essery, Eve V; McGrane, Mary M; Wong, Yat Ping; Spahn, Joanne M; Williams, Christine L

    2012-05-01

    Energy density is a relatively new concept that has been identified as an important factor in body weight control in adults and in children and adolescents. The Dietary Guidelines for Americans 2010 encourages consumption of an eating pattern low in energy density to manage body weight. This article describes the systematic evidence-based review conducted by the 2010 Dietary Guidelines Advisory Committee (DGAC), with support from the US Department of Agriculture's Nutrition Evidence Library, which resulted in this recommendation. An update to the committee's review was prepared for this article. PubMed was searched for English-language publications from January 1980 to May 2011. The literature review included 17 studies (seven randomized controlled trials, one nonrandomized controlled trial, and nine cohort studies) in adults and six cohort studies in children and adolescents. Based on this evidence, the 2010 Dietary Guidelines Advisory Committee concluded that strong and consistent evidence in adults indicates that dietary patterns relatively low in energy density improve weight loss and weight maintenance. In addition, the committee concluded that there was moderately strong evidence from methodologically rigorous longitudinal cohort studies in children and adolescents to suggest that there is a positive association between dietary energy density and increased adiposity. This review supports a relationship between energy density and body weight in adults and in children and adolescents such that consuming diets lower in energy density may be an effective strategy for managing body weight.

  8. Grip selection for sequential movements in children and adults with and without Developmental Coordination Disorder.

    Wilmut, Kate; Byrne, Maia

    2014-08-01

    When generating a movement adults favor grasps which start the body in an uncomfortable position if they end in a comfortable position (the end-state-comfort effect). In contrast, children with Developmental Coordination Disorder (DCD) select grasps which require little initial hand rotation even though they result in an uncomfortable end position. The current study considered grip selection of individuals with DCD when asked to make simple one step movements and when making more complex multi-staged movements. Adults with DCD (N=17, mean age 24:09, SD age=52months) and children with DCD (N=20, mean age 9:00, SD age=20months) and age and gender matched controls rotated a disc so an arrow pointed toward a specific target(s). Task complexity was increased by increasing the number of targets from 1 to 3. Planning for end-state-comfort was seen in all groups albeit to a lesser extent in children versus adults. The children with DCD showed fewer grips for end-state-comfort compared to their peers and this was explained by a propensity to select minimal initial rotation grasps. This result was mirrored in adults with DCD but only for the longest movement sequence. These results suggest some changes in ability from childhood to adulthood in individuals with DCD.

    Hernandez, Arturo E; Woods, Elizabeth A; Bradley, Kailyn A L

    2015-04-01

    The present study compared the neural correlates of language processing in children and adult Spanish-English bilinguals. Participants were asked to perform a visual lexical processing task in both Spanish and English while being scanned with fMRI. Both children and adults recruited a similar network of left hemisphere "language" areas and showed similar proficiency profiles in Spanish. In terms of behavior, adults showed better language proficiency in English relative to children. Furthermore, neural activity in adults was observed in the bilateral MTG. Age-related differences were observed in Spanish in the right MTG. The current results confirm the presence of neural activity in a set of left hemisphere areas in both adult and child bilinguals when reading words in each language. They also reveal that differences in neural activity are not entirely driven by changes in language proficiency during visual word processing. This indicates that both skill development and age can play a role in brain activity seen across development.

    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.

  5. From development to aging: Holistic face perception in children, younger and older adults.

    2017-01-01

    Few published reports examine the development of holistic face processing across the lifespan such that face-specific processes are adequately differentiated from general developmental effects. To address this gap in the literature, we used the complete design of the composite paradigm (Richler & Gauthier, 2014) with faces and non-face control objects (watches) to investigate holistic processing in children (8-10years), young adults (20-32years) and older adults (65-78years). Several modifications to past research designs were introduced to improve the ability to draw conclusions about the development of holistic processing in terms of face-specificity, response bias, and age-related differences in attention. Attentional focus (narrow vs. wide focus at study) influenced the magnitude of the composite effect without eliminating holistic face processing in all age groups. Young adults showed large composite effects for faces, but none for watches. In contrast, older adults and children showed composite effects for both faces and watches, although the effects for faces were larger. Our findings suggest that holistic processing, as measured by the composite effect, might be moderated by less efficient attentional control in children and older adults. The study also underscores the importance of including comparable complex objects when investigating face processing across the lifespan.

    1997-12-01

    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.

    Full Text Available Abstract Background Diffusely adherent Escherichia coli (DAEC have been considered a diarrheagenic category of E. coli for which several potential virulence factors have been described in the last few years. Despite this, epidemiological studies involving DAEC have shown inconsistent results. In this work, two different collections of DAEC possessing Afa/Dr genes, from children and adults, were studied regarding characteristics potentially associated to virulence. Results DAEC strains were recovered in similar frequencies from diarrheic and asymptomatic children, and more frequently from adults with diarrhea (P Citrobacter freundii strain have shown an improved ability to form biofilms in relation to the monocultures. Control strains have shown a greater diversity of Afa/Dr adhesins and higher frequencies of cellulose, TTSS, biofilm formation and induction of IL-8 secretion than strains from cases of diarrhea in children. Conclusions DAEC strains possessing Afa/Dr genes isolated from children and adults represent two different bacterial populations. DAEC strains carrying genes associated to virulence can be found as part of the normal microbiota present in asymptomatic children.

    The purpose of this study was to identify whether cortisol reactivity to a stressful laboratory event was related to children's memory of that event and to determine whether this relation was comparable to that observed in adults. Nine- to 12-year-olds and young adults completed an impromptu speech and math task during which repeated cortisol samples and self-reported stress ratings were collected. Two weeks later, participants' memory for the tasks was examined. Greater cortisol reactivity was associated with enhanced memory, most prominently in children. Self-reported stress was unrelated to memory. Findings reveal that an important mechanism underlying the association between emotion and memory in adults, namely activation of the hypothalamic pituitary adrenal axis, appears to operate similarly in late childhood. Findings also demonstrate that positive associations between cortisol reactivity and memory are evident when the event that actually elicited that reactivity serves as the to-be-remembered event.

    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.

    Introduction In the adult population, assessment of blood consumption (ABC) score [penetrating mechanism, positive focused assessment sonography for trauma (FAST), systolic blood pressure  120] ≥2 identifies trauma patients who require massive transfusion (MT) with sensitivity and specificity of 75 and 86%. We hypothesized that the adult criteria cannot be applied to children, as the vital sign cut-offs are not age-adjusted. We aimed to determine if the use of a shock index, pediatric age-adjusted (SIPA) would improve the discriminate ability of the ABC score in children. Materials and Methods A retrospective review of children age 4 to 15 who received a packed red blood cell (PRBC) transfusion during admission for trauma between 2008 and 2014 was performed. We compared the sensitivity and specificity of ABC score ≥ 2, elevated SIPA, and age-adjusted ABC score (ABC-S) utilizing SIPA in place of HR and BP, to determine the need for MT. Results A total of 50 children were included, 31 received PRBC transfusion within 6 hours of injury, 7 children had a positive FAST, and 3 suffered penetrating trauma, all in the early transfusion group. ABC score ≥ 2 is 29% sensitive and 100% specific at predicting need for MT while ABC-S score ≥ 1 is 65% sensitive and 84% specific. Conclusions Adult-based criteria for activation of MT perform poorly in the pediatric population. The use of SIPA modestly improves the sensitivity of the ABC score in children; however, the sensitivity and specificity of this score are still worse than when used in an adult population. This suggests the need to develop a new score that takes into account the low rate of penetrating trauma and positive FAST in the pediatric population.

    2007-01-01

    Full Text Available The aim of this research is to describe the reaction of pupils and adults who work in school to violence. Reactions to violence, aimed at the child personally, have to be differentiated from the reactions to the violent scenes that the child witnesses. The analyzed data, collected in the questionnaires within the program of fighting violence which was started by UNICEF in 2005, comprise the answers of 25.056 pupils and 4.793 adults from 71 schools in Serbia. The results indicate that the pupils react to violence inconsistently and that in their repertoire they have both constructive and non-constructive ways of reacting. One half of the pupils are ready to seek help from others in case of being in danger, and widespread are also those reactions (answering by aggression or submissiveness which substantiate further violence. Every tenth pupil who is a violence victim just tolerates and conceals violence. If they witness violence, 11% of the pupils consequently distance themselves from helping. The pupils who are violence victims do not feel abandoned by their peers, 73% of them said that their friends helped them. Although adults themselves estimate highly their own readiness and the ability to react to violence, the measures undertaken by them are not assessed well on the part of pupils. In the conclusion, there is the elaboration of all the measures which can be used to stop self-reproduction of violent behavior in school and the emphasis on the need for the programs for prevention of school violence which would be based on the inclusion of the whole school collective, and especially pupils.

  16. Effects of orthographic consistency on eye movement behavior: German and English children and adults process the same words differently.

    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.

    Full Text Available Lichen sclerosus et atrophicus (LSA is a chronic inflammatory dermatosis that results in white plaques with epidermal atrophy usually affecting the genital area in both adults and children. The causes of LSA are not clear but possible predisponsing factors include trauma, infection (borrelia, human papilloma virus, autoimmune diseases and local irritation. This study is a retrospective case review of children and adults with LSA attending the department of Dermatology at the Royal Infirmary in Edinburgh, clinical notes for 22 patients were reviewed for age, sex, personal and familial history, symptoms associated diseases and clinical course and treatment. The mean ages at diagnosis of LSA in 9 children (8F: 1M and 13 adults (13 F were 7 and 57.5 years respectively. The mean duration of illness was 1.5 year in children and 5.5 year in adults. Itching was the most common symptom in both children and adults. Children also suffered with difficulties in defaecation and in micturation , dribbling, incontinence, constipation and bleeding. Atopy and hypothyroidism were common associated conditions in both the groups. Squamous cell carcinoma of the vulva was confirmed in two adult patients. This study showed the variable symptoms in children, which seemed more severe than in the adult population.

  1. Gaze-contingent reinforcement learning reveals incentive value of social signals in young children and adults.

    While numerous studies have demonstrated that infants and adults preferentially orient to social stimuli, it remains unclear as to what drives such preferential orienting. It has been suggested that the learned association between social cues and subsequent reward delivery might shape such social orienting. Using a novel, spontaneous indication of reinforcement learning (with the use of a gaze contingent reward-learning task), we investigated whether children and adults' orienting towards social and non-social visual cues can be elicited by the association between participants' visual attention and a rewarding outcome. Critically, we assessed whether the engaging nature of the social cues influences the process of reinforcement learning. Both children and adults learned to orient more often to the visual cues associated with reward delivery, demonstrating that cue-reward association reinforced visual orienting. More importantly, when the reward-predictive cue was social and engaging, both children and adults learned the cue-reward association faster and more efficiently than when the reward-predictive cue was social but non-engaging. These new findings indicate that social engaging cues have a positive incentive value. This could possibly be because they usually coincide with positive outcomes in real life, which could partly drive the development of social orienting.

    This study examined how an adult's descriptions of a situation could influence children's appraisal, feelings, and subsequent psychological functions. After baseline measures, 81 middle-class Singaporean kindergarten children (Mage  = 5.6 years, SD = 0.6) were exposed to an ambiguous accident and provided with positive, negative, or no descriptions of the accident. Children's appraisal of the experience, feelings of pleasantness, motivation to play a new game, confidence in playing the new game well, and performance on the new game were measured. The results revealed that the descriptions of the accident influenced children's appraisal, feelings of pleasantness, motivation to play a new game, confidence in playing the new game well, and performance on the new game.

    This study examines the relationships between perceived and self-reported parent verbal aggression and their young adult children's intimate partner violence (IPV) victimization and perpetration. Two hundred undergraduate students completed an in-person self-administered survey measuring IPV victimization and perpetration, as well as perceived parent verbal aggression. Three-hundred and eighty-six mail surveys were also sent to their parents; 79% of parents returned the surveys. Results indicate that perceived mother and father verbal aggression was related to higher levels of victimization and perpetration across several forms of IPV for both daughters and sons. The data appear to support theory that suggests parents of the same sex as their children are stronger models for aggressive behavior (Bandura, 1986). In addition, there were some differences in perceived and self-reported data for ratings of parent verbal aggression. Results of this investigation indicate that perceived parent communication has a significant impact on young adult children's victimization and perpetration of violence in intimate partner relationships. The findings also suggest that interventions aimed at developing and enhancing parent communication skills can help prevent or reduce the risk of young adult children becoming involved in violent relationships, as well as reducing risk factors for other adverse health problems.

    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.

    Salivary cortisol is a steroid hormone that is produced in the hypothalamic-pituitary-adrenal axis and secreted into saliva when persons are under stress. High levels of cortisol in saliva can be produced by many different factors, including obesity and certain psychological disorders. The articles selected for inclusion in this review were identified using Google Scholar and Medline, and this search obtained a total of 57 items. The validity of these studies was established according to the degree of evidence presented, by citations and by their applicability to the healthcare context in Spain. Specifically, this review takes into consideration studies of salivary cortisol and stress in children and adults, and those examining the relation between high levels of salivary cortisol and other disorders such as anxiety, attention-deficit/hyperactivity disorder, social phobia or emotional deprivation. These studies show that salivary cortisol is a clear indicator of stress in both children and adults. High levels of this hormone in saliva are associated with the following main consequences: reduced immune function, affecting healing and thus prolonging recovery time; delayed growth in children; increased blood pressure and heart rate in both children and adults.

  6. The influence of labels and facts on children's and adults' categorization.

    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.

  7. Auditory habituation to simple tones: reduced evidence for habituation in children compared to adults

    Full Text Available Habituation – the response decrement to repetitively presented stimulation - is a basic cognitive capability and suited to investigate development and integrity of the human brain. 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.

    This study examined trace metal levels in scalp hair taken from 122 children and 27 adult residents of three small northern Alberta (Canada) Indian villages, one of which is situated close to the world's first tar sands oil extraction plants. The three communities studied were: Fort McKay (the exposed village), Fort Chipewyan (also in the tar sands ecosystem but distant from the plants), and Garden River (not in the tar sands ecosystem). Inductively coupled argon plasma emission spectroscopy was used to determine hair sample metal content. Nineteen metals were included in data analysis. Children from Fort McKay had the highest average hair lead, cadmium and nickel levels. Chromium levels were approximately equal in hair from Fort McKay and Garden River children, and significantly elevated above levels found in the hair of Fort Chipewyan children. Children from Garden River showed highest hair levels of eight metals: vanadium, aluminum, iron, manganese, barium, zinc, magnesium and calcium. Fort Chipewyan children had the highest hair levels of copper, but the lowest levels of all other metals. Among adults, hair lead, nickel and cadmium levels were highest in Fort McKay residents, while phosphorous and vanadium were highest in hair from Garden River residents. Bioaccumulation of lead, cadmium, nickel and chromium in hair from Fort McKay residents may be related to exposure to extraction plant pollution. Plant stack emissions are known to contain appreciable amounts of lead, nickel and chromium. Spills into the Athabasca River, until recently the source of Fort McKay drinking water, have been reported from plant wastewater holding ponds, known to contain elevated levels of lead, nickel and cadmium. An increased number of significant metal-metal correlations in hair metal levels for Fort McKay children suggests a richer source of multiple metal exposure, relative to children in the other two communities.

Parmi eux, 568 étaient des nouveaux patients, et 13 avaient déjà été traités ; pour 7 d'entre eux, le statut était inconnu. Comparés aux adultes, les enfants avec une TB nouvelle avaient une plus grande prévalence de TB extra pulmonaire (75% contre 34% ; OR 5,7 ; IC95% 3,6–9,0) et une prévalence plus faible de TB pulmonaire frottis positif (11% contre 45% ; OR 0,15 ; IC95% 0,3–0,3). Les adultes âgés de ⩾55 ans avaient une prévalence plus élevée de TB pulmonaire à frottis négatif (38% contre 21% ; OR 2,4 ; IC95% 1,5–3,8). Le succès du traitement de la TB a été de 83% pour l'ensemble du groupe, mais seulement de 67% pour les patients âgés de ⩾65 ans avec un taux de létalité de 18%.Conclusion : Les enfants et les adultes plus âgés constituent 45% du fardeau de la TB au Vanuatu. Les différences constatées en termes de profil de la maladie et de résultats thérapeutiques moins bons chez les adultes âgés ont des implications en matière de politique et de pratiques.

    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.)

    Attention deficit hyperactivity disorder (ADHD) is associated with decreased ventral-striatal responsiveness during reward anticipation. However, previous research mostly focused on adults with heterogeneous ADHD subtype and divers drug treatment status while studies in children with ADHD are sparse. Moreover, it remains unclear to what degree ADHD is characterized by a delay of normal brain structure or function maturation. We therefore attempt to determine whether results from structural and functional magnetic resonance imaging (fMRI) are associated with childhood and adult ADHD combined subtype (ADHD-CT). This study used fMRI to compare VS structure and function of 30 participants with ADHD-CT (16 adults, 14 children) and 30 controls (20 adults, 10 children), using a monetary incentive delay task. Joint analyses of structural and functional imaging data were conducted with Biological Parametric Mapping. Reward anticipation elicited decreased ventral-striatal responsiveness in adults but not in children with ADHD-CT. Children and adults with ADHD showed reduced ventral-striatal volume. Taking these gray matter differences into account, the results remained the same. These results suggest that decreased ventral-striatal responsiveness during reward anticipation is present in adults but not in children with ADHD-CT, irrespective of structural characteristics. The question arises whether ventral-striatal hypoactivity is an ADHD correlate that develops during the course of illness.

    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.

    This study examined the kinematic features of wheelchair propulsion in two neurologically matched groups of adults and children with uncomplicated spinal cord injury. The average mass and age of the pediatric group was much smaller than the adult group (37.4kg and 11.3 years vs 68.5kg and 33.5 years). Each subject propelled his/her own chairs and new, low-mass wheelchairs at a steady, nominal speed of 2 m/sec across a level surface. Three dimensional video analysis determined the movement of upper body angles (elbow, shoulder, trunk, and shoulder abduction) based on reflective markers placed on the subjects' shoulder, elbow, wrist, and hip joints. Analysis of the temporal factors showed that although the average group overground velocities of the adult group (2.4m/sec) were significantly greater than the pediatric group (2.3 m/sec), the two groups spent comparable proportions of the wheeling cycle in propulsion (24%). Analysis of the angular kinematics (elbow, shoulder, and shoulder abduction angular changes over a time normalized wheeling cycle) showed that whereas the pediatric group did show significant absolute angular differences from the adult group, the angular changes over time were the same in both groups. The implications of this work are that, for the first time, it can be said that children propel their wheelchairs in the same manner as adults. In addition, these data were similar to those previously reported in athletic adult populations. We conclude that published data from adult wheelchair users may be applied to pediatric wheelchair users, thus providing a basis for pediatric wheelchair prescription.(ABSTRACT TRUNCATED AT 250 WORDS)

    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.

    We tested Apperly and Butterfill's (2009, Psychological Review, 116, 753) theory that humans have two mindreading systems whereby the efficient-system guiding anticipatory glances displays signature limits that do not apply to the flexible system guiding verbal predictions. Experiments 1 and 2 tested urban Mainland-Chinese adults (n = 64) and Experiment 3 tested Semai children living in the rainforests of Peninsular Malaysia (3- to 4-year-olds, n = 60). Participants - across different ages, groups and methods - anticipated others' false-beliefs about object-location but not object-identity. Convergence in signature limits signalled that the early-developing efficient system involved minimal theory-of-mind. Chinese adults and older Semai children showed flexibility in their direct predictions. The flexible mindreading system in ascribing others' beliefs as such was task-sensitive and implicated maturational and cultural contributions.

    This research examines adults', and for the first time, children's and adolescents' reaction to being ostracized and included, using an on-line game, 'Cyberball' with same and opposite sex players. Ostracism strongly threatened four primary needs (esteem, belonging, meaning, and control) and lowered mood among 8- to 9-year-olds, 13- to 14-year-olds, and adults. However, it did so in different ways. Ostracism threatened self-esteem needs more among 8- to 9-year-olds than older participants. Among 13- to 14-year-olds, ostracism threatened belonging more than other needs. Belonging was threatened most when ostracism was participants' first experience in the game. Moreover, when participants had been included beforehand, ostracism threatened meaning needs most strongly. Gender of other players had no effect. Practical and developmental implications for social inclusion and on-line experiences among children and young people are discussed.

    The overall vegetable and animal protein combinations of the diet in Northern Mexico were determined through a dietary population survey. Vegetable sources made up 45% and animal protein was 55% (45V/55A). Further combinations of up to 100% vegetable protein dietary mixtures (100V) were studied to test the sensibility of the variations on protein requirements of pre-school, school children and adults. Diets were analyzed for amino acid composition and in vivo protein digestibility in rats to estimate true protein requirements according to FAO/WHO/UNU (1985). The effect on the pre-school group showed the widest variation with 1.46 g/kg/day in the 45V/55A to 2.63 in the 100V. For the school-aged children and adults the variations were 1.15-1.79 and 0.94-0.84 g/kg/day respectively.

    Observational studies of breakfast frequency in children and adults suggest an inverse (protective) association between the frequency of eating breakfast and the risk for obesity and chronic diseases such as type 2 diabetes. More prospective studies with stronger designs are needed, as are experimental studies on this topic. In addition, above and beyond breakfast frequency, the roles of dietary quality and composition need to be studied in the context of eating or skipping breakfast. Experimental studies are also necessary to rigorously test causality and biological mechanisms. Therefore, we conducted 2 pilot experimental studies to examine some of the effects of breakfast skipping and breakfast composition on blood glucose and appetite in children and adults. Our results suggest that breakfast frequency and quality may be related in causal ways to appetite controls and blood sugar control, supporting the hypothesis that the breakfast meal and its quality may have important causal implications for the risk of obesity and type 2 diabetes.

    The long-term toll of war captivity on secondary traumatization (ST) on adult children has recently been exemplified. Several studies have also revealed that indirect exposure to trauma might be accompanied by positive psychological changes. This study examined secondary posttraumatic growth (SG) among adult children of former prisoners of war (ex-POWs' children) who were compared with adult children of comparable veterans (controls' children). Furthermore, we examined the role of five-factor personality traits in the associations between exposure to stress stemming from fathers' behaviors, ST symptoms, and SG. Participants were Israeli ex-POWs' children (N = 98) and controls' children (N = 90), whose fathers fought in the 1973 Yom Kippur War. Results show that ex-POWs' children reported higher levels of SG compared with controls' children. ST symptoms were found to mediate the association between research group and SG, and the direct effect was found to be conditioned at the levels of participants' extroversion. Furthermore, among ex-POWs' children, extroversion and openness to the experience personality traits, as well as exposure to stress, were found to predict SG. Forty years after the war ended, the experience of living with ex-POWs is associated with ex-POWs' children SG that might be more related to their exposure to stress and personality traits than their ST symptoms. Clinical interventions aiming to increase the levels of SG among indirect victims of captivity should consider the influence of pretrauma resources, trauma characteristics, and posttrauma factors.

    Previous studies have reported own-age biases in younger and older adults in gaze following. We investigated own-age biases in social attentional processes between adults and children by focusing on two aspects of the joint attention process; the extent to which people attend towards an individual's face, and the extent to which they fixate objects that are looked at by this person (i.e., gaze following). Participants viewed images that always contained a child and an adult who either looked towards each other or each looked at objects located to their side. Observers consistently, and rapidly fixated the actor's faces, though the children were faster to fixate the child's face than the adult's faces, whilst the adults were faster to fixate on the adult's face than the child's face. The children also spent significantly more time fixating the child's face than the adult's face, and the opposite pattern of results was found for the adults. Whilst both adults and children prioritized objects when they were looked at by the actor, both groups showed equivalent levels of gaze following, and there was no own-age bias for gaze following. Our results show an own-age bias for prioritizing faces, but not gaze following.

  10. Functional imaging of numerical processing in adults and 4-y-old children.

    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

    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.

    2014-10-01

    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.

    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.

    2016-01-01

    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.

    Accumulating evidence suggests an increased prevalence of vitamin D deficiency in the Middle East and North African countries. Sunlight has long been recognized as a major provider of vitamin D and lighter skin color has been associated with better vitamin D status. In this context, we aimed to determine whether 25-hydroxyvitamin D[25-(OH)D] concentrations are related to skin color, sun exposure and gender among healthy Saudi children and adults. A total of 808 Saudi children (age=14.6±0.04years) and 561 (age=31.4±0.3years) adults of both genders were included in this study. Levels of sun exposure and skin color were determined using a standard questionnaire. Anthropometry and plasma 25-(OH)D concentrations were analyzed. On the basis of duration of sun exposure (20min), a significantly lower concentration of 25-(OH)D (40.9±1.2 vs. 35.5±1.8nmol/l; pcolor on vitamin D status of children or adults, except in dark-skinned boys who had lower 25(OH)D concentrations associated with limited sun exposure.

    CKD has been linked with cognitive deficits and affective disorders in multiple studies. Analysis of structural and functional neuroimaging in adults and children with kidney disease may provide additional important insights into the pathobiology of this relationship. This paper comprehensively reviews neuroimaging studies in both children and adults. Major databases (PsychLit, MEDLINE, WorldCat, ArticleFirst, PubMed, Ovid MEDLINE) were searched using consistent search terms, and studies published between 1975 and 2012 were included if their samples focused on CKD as the primary disease process. Exclusion criteria included case reports, chapters, and review articles. This systematic process yielded 43 studies for inclusion (30 in adults, 13 in children). Findings from this review identified several clear trends: (1) presence of cerebral atrophy and cerebral density changes in patients with CKD; (2) cerebral vascular disease, including deep white matter hyperintensities, white matter lesions, cerebral microbleeds, silent cerebral infarction, and cortical infarction, in patients with CKD; and (3) similarities in regional cerebral blood flow between patients with CKD and those with affective disorders. These findings document the importance of neuroimaging procedures in understanding the effect of CKD on brain structure, function, and associated behaviors. Results provide a developmental linkage between childhood and adulthood, with respect to the effect of CKD on brain functioning across the lifespan, with strong implications for a cerebrovascular mechanism contributing to this developmental linkage. Use of neuroimaging methods to corroborate manifest neuropsychological deficits or perhaps to indicate preventive actions may prove useful to individuals with CKD.

    Borderline personality disorder (BPD) involves disruptions in attachment, self, and self-regulation, domains conceptually similar to developmental tasks of early childhood. Because offspring of mothers with BPD are at elevated risk of developing BPD themselves (White, Gunderson, Zanarini, & Hudson, 2003), studying them may inform precursors to BPD. We sampled 31 children age 4-7 whose mothers have BPD and 31 normative comparisons. We examined relationships between mothers' Adult Attachment Interview (AAI) representations (George, Kaplan, & Main, 1984), mothers' observed parenting, and children's narrative representations. Replicating previous studies, mothers with BPD were more likely to be classified as preoccupied and unresolved on the AAI. In a larger sample, which included the current one, we also replicated two underlying AAI dimensions found in normative samples (Roisman, Fraley, & Belsky, 2007; Whipple, Bernier, & Mageau, 2011). Controlling for current mood, anxiety, and other personality disorders, mothers with BPD were significantly higher than were comparisons on the preoccupied/unresolved, but not the dismissive, dimension. Children's narrative representations relevant to disruptions in attachment (fear of abandonment and role reversal), self (incongruent child and self/fantasy confusion), and self-regulation (destruction of objects) were significantly correlated with the preoccupied/unresolved, but not the dismissive, dimension. Furthermore, mothers' parenting significantly mediated the relationship between the preoccupied/unresolved dimension and their children's narrative representations of fear of abandonment.

    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.

    BACKGROUND: Neuroimaging studies have shown structural alterations in several brain regions in children and adults with attention deficit hyperactivity disorder (ADHD). Through the formation of the international ENIGMA ADHD Working Group, we aimed to address weaknesses of previous imaging studies...... compared with controls in the mega-analysis. There was no difference in volume size in the pallidum (p=0·95) and thalamus (p=0·39) between people with ADHD and controls. Exploratory lifespan modelling suggested a delay of maturation and a delay of degeneration, as effect sizes were highest in most...... and adults for the pallidum (p=0·79) or thalamus (p=0·89). Case-control differences in adults were non-significant (all p>0·03). Psychostimulant medication use (all p>0·15) or symptom scores (all p>0·02) did not influence results, nor did the presence of comorbid psychiatric disorders (all p>0...

    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.

    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.

    Smith-Magenis Syndrome (SMS) is a genetic neurodevelopmental disorder caused by a microdeletion on chromosome 17p11.2. This syndrome is characterized by a distinctive profile of physical, medical and neuropsychological characteristics. The latter include general mental disability, with the majority of individuals falling within the mild to moderate range. This study reports a detailed cognitive assessment of children and adults with SMS with the use of the Wechsler intelligence scales at three distinct levels of analysis: full scale IQ, factorial indices, and subtests. Child and adult samples were each compared to samples of age and gender-matched typically developing individuals. To our knowledge, this is the first study to systematically analyse the cognitive profile of individuals with SMS in Southern Europe. The present study confirmed mental disability, particularly within the moderate category, as a consistent feature of children and adults with SMS. Furthermore, both child and adult samples evidenced significant impairments in all four indices when compared with their typically developing counterparts. A specific pattern of strengths and weaknesses was discernible for both samples, with Verbal Comprehension emerging as a relative strength, whereas Working Memory appeared as a relative weakness. Finally, with the exception of two subtests in the perceptual domain, we found no evidence for a general cognitive decline with age.

    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.

    INTRODUCTION: Only a limited reference material for acoustic rhinometry (AR) exists for school children most often calculated as the minimum cross-sectional area (MCA) in the non-decongested nose. We want to establish a set of reference values for MCA and nasal volumes for both adults and children...... and include values also for the decongested nose and determine the most sensitive measurement for change in nasal patency. METHOD: Data from two studies were used; one comprising of 53 (20M, 33F) school children, age 9-11 years, and one comprising 146 (127M, 19F) healthy workers in the wood industry....... Measurements by acoustic rhinometry were done before and after decongestion with two puffs of oxymethazoline nasal spray (1mg/ml). RESULTS: We found the decongested nasal volume (2-5 cm) to be 3.71 cm3 (3.58 - 3.84) in school children and 5.44 cm3 (5.21-5.67) in adults. We found the volume from 2-5 cm...

    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.

    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.

    This study investigated explicit knowledge of autobiographical memory functions using a newly developed questionnaire. European and Asian American adults (N = 57) and school-aged children (N = 68) indicated their agreement with 13 statements about why people think about and share memories pertaining to four broad functions-self, social, directive and emotion regulation. Children were interviewed for personal memories concurrently with the memory function knowledge assessment and again 3 months later. It was found that adults agreed to the self, social and directive purposes of memory to a greater extent than did children, whereas European American children agreed to the emotion regulation purposes of memory to a greater extent than did European American adults. Furthermore, European American children endorsed more self and emotion regulation functions than did Asian American children, whereas Asian American adults endorsed more directive functions than did European American adults. Children's endorsement of memory functions, particularly social functions, was associated with more detailed and personally meaningful memories. These findings are informative for the understanding of developmental and cultural influences on memory function knowledge and of the relation of such knowledge to autobiographical memory development.

    Mexico, with 1 of the highest obesity prevalences in the world, instituted a 10% excise tax for any sugar-sweetened beverage (SSB) starting on 1 January 2014. Understanding the recent patterns and trends in beverage intake and sales in Mexico provides both background and baseline data for the importance of SSBs and other beverages in the Mexican diet. We analyzed a single 24-h dietary recall from 2 nationally representative surveys: the Mexican Nutrition Survey 1999 (n = 6049) and the National Health and Nutrition Survey 2012 (n = 10,343). To describe trends and patterns in beverages, we calculated the volume and energy intake per capita and per consumer and the proportion of consumers of each beverage group in each survey. A commercial sales dataset was used to describe beverage sales trends from 1999 to 2012. From 1999 to 2012, total daily energy from beverages increased among children aged 5-11 y (+45.3 kcal), females aged 12-19 y (+57.3 kcal), and adult females aged 20-49 y (+96.4 kcal) (P agua fresca (fruit water made in stalls or at home, usually with added sugars), and fruit drinks among children aged 5-11 y and females aged 12-19 y and caloric coffee/tea, soda, and agua fresca among adult females aged 20-49 y. In 2012, beverages represented 17.5% (325 kcal) and 19.0% (382 kcal) of the total daily energy intake per capita in children aged 1-19 y and adults aged ≥20 y, respectively. In 2012, flavored milk beverages, caloric soda, and high-fat milk were the top 3 major contributors to total daily energy intake per capita in all children aged 1-19 y. Caloric soda, caloric coffee/tea, and agua fresca were the top 3 major energy contributors in adults aged ≥20 y. From 1999 to 2012, sales of soda, fruit-flavored drinks, and flavored waters increased. In conclusion, consumption of several beverages with added sugars increased among children and adult females in Mexico. Because caloric soda is currently 1 of the top beverages consumed, a 10% tax on SSBs might

Patients who started radiotherapy within two months after surgery have better survival, but again this was not statistically significant, probably due to the small number of patients receiving delayed radiotherapy (p=0.2231(Graph5. CONCLUSION Based on this factors standard and high risk group could be defined. Combined chemotherapy should to be investigated particularly for high risk subgroup. Future research should be done to define new therapeutic modalities (gene therapy, compounds active in tumor antiangiogenesis etc.

    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.

    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.

    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.

    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 Our ability to read other people’s non-verbal signals gets refined throughout childhood and adolescence. How this is paralleled by brain development has been investigated mainly with regards to face perception, showing a protracted functional development of the face-selective visual cortical areas. In view of the importance of whole-body expressions in interpersonal communication it is important to understand the development of brain areas sensitive to these social signals.Here we used functional magnetic resonance imaging (fMRI to compare brain activity in a group of 24 children (age 6-11 and 26 adults while they passively watched short videos of body or object movements. We observed activity in similar regions in both groups; namely the extra-striate body area (EBA, fusiform body area (FBA, posterior superior temporal sulcus (pSTS, amygdala and premotor regions. Adults showed additional activity in the inferior frontal gyrus. Within the main body-selective regions (EBA, FBA and pSTS, the strength and spatial extent of fMRI signal change was larger in adults than in children. Multivariate Bayesian analysis showed that the spatial pattern of neural representation within those regions did not change over age.Our results indicate, for the first time, that body perception, like face perception, is still maturing through the second decade of life.

    Both children and adults can learn motor sequences quickly in one learning session, yet little is known about potential age-related processes that underlie this fast sequence acquisition. Here, we examined the progressive performance changes in a one-session modified serial reaction time task in 6- and 10-year-old children and adults. We found that rapid sequence learning, as reflected by reaction time (RT), was comparable between groups. The learning was expressed through two behavioral processes: online progressive changes in RT while the task was performed in a continuous manner and offline changes in RT that emerged following a short rest. These offline and online RT changes were age-related; learning in 6-year-olds was primarily reflected through the offline process. In contrast, learning in adults was reflected through the online process; and both online and offline processes occurred concurrently in 10-year-olds. Our results suggest that early rapid sequence learning has a developmental profile. Although the unifying mechanism underlying these two age-related processes is unclear, we discuss possible explanations that need to be systematically elucidated in future studies. PMID:28223958

    The present study investigates the ability of Down Syndrome (DS) adults to reason: (a) deductively with transitivity (linear and reverse relations) and categorical syllogisms (all-some relations); (b) inductively with classical verbal analogies and non-verbal analogical reasoning (Raven's Coloured Progressive Matrices); and (c) to retain information in short-term memory. The results have shown that: (i) The Down Syndrome adults did not differ from typically developing children, matched on expressive and verbal ability, in transitivity and non-verbal analogical thinking; (ii) they differed in categorical reasoning, classical verbal analogies and short-term memory. Application of a structural model demonstrated that, despite differences in slope means in the three measures, the structure of functioning within-and-across all domains of cognition tests and its growth pattern, equally reliable and coherent, goes in parallel for the Down Syndrome adults and the typically developing children. The results are discussed within the context of the two-group developmental and difference approach.

    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.

    Using a serological test, different criteria have been established for classifying a case as primary or secondary dengue virus infection. Considering the dengue epidemiological situation in Cuba, IgG antibody response to dengue virus infection in serum samples from children and adults with a dengue 3 infection, in Havana city during the 2001-2002 epidemic was evaluated. Samples were collected on days 5-7 of fever onset and tested by an ELISA inhibition. A total of 713 serum samples positive for IgM antibody, 93 from children and 620 from adult patients were studied. Serum samples collected from healthy blood donors and patients not infected with dengue were included as controls. An IgG primary infection pattern was observed in sera collected from children, with titers of or =1280 (83.9%), respectively. These results permitted the definition of a primary or secondary case of dengue virus infection in serum samples collected during the acute phase of dengue virus infection.

    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.

    Vitamin D deficiency is implicated in several calcium deficiency-related disease conditions. We aimed to investigate vitamin D status and its association with consumption frequencies of various dairy products in Saudi population. Subjects consisted of 820 children (327 boys; mean age 14.9 yrs and 493 girls; 14.8 yrs) and 565 adults (249 men, 27.9 yrs and 316 women 32.2 yrs). We estimated the consumption frequencies of various dairy food products (fresh milk, powdered milk, laban, yoghurt and cheese) using a qualitative food frequency questionnaire and serum level of 25-hydroxyvitamin D (25 (OH) D). Associations between variables of interest were assessed by Pearson correlation analysis. Among the study subjects, 80% boys, 90% girls, 64% men and 50% women had deficient/insufficient levels of vitamin D. Modest associations were found between mean serum 25 (OH) D concentration and fresh milk consumption in children (r=0.11) (especially in girls (r=0.12)), and overall dairy products consumption in women (r=0.12). Conclusion: Results indicated widespread vitamin D deficiency in Saudi Arabian children and adults. High level of vitamin D deficiency and a lack of strong correlation between dairy product consumption and serum level of vitamin D imply a need for adequate fortification of milk and other dairy products with vitamin D.

    Full Text Available Astri Syse1, Gjøril B Aas1, Jon H Loge2,31Cancer Registry of Norway, 2Oslo University Hospital, 3University of Oslo, Oslo, NorwayBackground: Today many people are choosing to have children later in life. 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. Parental cancer is more common than

    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.

    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. We find some evidence that parents' marital quality influences children's support for divorce and premarital sex. More important, our analyses show that parents' marital quality facilitates the intergenerational transmission of attitudes. Parents' attitudes toward premarital sex, cohabitation, and being single are more strongly linked to those same attitudes among their young adult children when parents' marital quality is high than when it is low.

  4. Functional lateralization of speech processing in adults and children who stutter

    Full Text Available Developmental stuttering is a speech disorder in fluency characterized by repetitions, prolongations and silent blocks, especially in the initial parts of utterances. Although their symptoms are motor related, people who stutter show abnormal patterns of cerebral hemispheric dominance in both anterior and posterior language areas. It is unknown whether the abnormal functional lateralization in the posterior language area starts during childhood or emerges as a consequence of many years of stuttering. In order to address this issue, we measured the lateralization of hemodynamic responses in the auditory cortex during auditory speech processing in adults and children who stutter, including preschoolers, with near-infrared spectroscopy (NIRS. We used the analysis-resynthesis technique to prepare two types of stimuli: (i a phonemic contrast embedded in Japanese spoken words (/itta/ vs. /itte/ and (ii a prosodic contrast (/itta/ vs. /itta?/. In the baseline blocks, only /itta/ tokens were presented. In phonemic contrast blocks, /itta/ and /itte/ tokens were presented pseudo-randomly, and /itta/ and /itta?/ tokens in prosodic contrast blocks. In adults and children who do not stutter, there was a clear left-hemispheric advantage for the phonemic contrast compared to the prosodic contrast. Adults and children who stutter, however, showed no significant difference between the two stimulus conditions. A subject-by-subject analysis revealed that not a single subject who stutters showed a left advantage in the phonemic contrast over the prosodic contrast condition. These results indicate that the functional lateralization for auditory speech processing is in disarray among those who stutter, even at preschool age. These results shed light on the neural pathophysiology of developmental stuttering.

    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.

    Confirmatory factor analyses of the commonly used 11 subtests of the Wechsler child and adult intelligence scales were accomplished for 137 children and 117 adults with high functioning autism (HFA) and for comparable age groups from the standardization samples contained in the Wechsler manuals. The objectives were to determine whether the structure of intelligence in HFA groups was similar to that found in the normative samples, and whether a separate "social context" factor would emerge that was unique to HFA. Four-factor models incorporating a Social Context factor provided the best fit in both the autism and normative samples, but the subtest intercorrelations were generally lower in the autism samples. Findings suggest similar organization of cognitive abilities in HFA, but with the possibility of underconnectivity or reduced communication among brain regions in autism.

    Poverty is associated with an increased risk for psychological problems. Even with this increased risk for mental health problems and need for care, many low-income adults and families do not receive treatment because of logistical, attitudinal, and systemic barriers. Despite significant barriers to obtaining care, research suggests that low-income individuals show significant benefit from evidence-based mental healthcare. In this article, we review the link between poverty and mental health, common barriers to obtaining mental health services, and treatment studies that have been conducted with low-income groups. Finally, we discuss the implications of the research reviewed and offer recommendations for clinicians working with low-income children or adults, highlighting the importance of evidence-based care, extensive outreach, and empathic respect.

    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 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.

  11. Musical hallucinations in normal children and adult non-psychiatric population.

    Aziz, Victor

    2009-01-01

    A descriptive account of musical hallucinations of a series of 19 people is presented. Five people reported the onset of hallucination before adulthood. In this paper we demonstrate that musical hallucinations are not necessarily pathological and can occur as a normal experience in people (children and adults) who have no contact with mental health services and no concurrent mental disorder. This is also the first paper to recognise that children can experience musical hallucinations. Also, we show that musical hallucinations are more common than previously thought, but people do not report their occurrence. It seems plausible that in musical hallucinations there is an insult to the ear or brain that produces a change in quality of these images, converting them to a psychotic experience. Musical hallucinations should be regarded as a continuum with normal experiences and clinical syndromes.

    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.

    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.

    The prevalence and types of psychiatric disorders were studied in a clinical sample of 89 individuals with atypical autism (AA) first seen as children, and 258 matched controls from the general population using data from the nationwide Danish Psychiatric Central Register. The average observation...... is not seen to be associated with any specific mental disorder. Schizophrenia spectrum disorders were the most commonly associated psychiatric disorders, diagnosed at least one time in 34.8% of the AA cases. Our findings underscore that it is important for clinicians working in adult psychiatric services...

    Chinese societies like most others are experiencing social change that impacts on models of care for older parents. There is tension between social change and traditional values of filial piety. The eldest son and his wife are expected to care for aged parents but that can be a challenge in modern industrial societies. This paper reports on research undertaken in Taiwan to explore changing values for aged care. It aimed to investigate how the roles and responsibilities of adult children of nursing home residents are changing. It involved aged care facility residents, their families and professional carers.

  17. 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.

    During the first years of life, sensory modalities communicate with each other. This process is fundamental for the development of unisensory and multisensory skills. The absence of one sensory input impacts on the development of other modalities. Since 2008 we have studied these aspects and developed our cross-sensory calibration theory. This theory emerged from the observation that children start to integrate multisensory information (such as vision and touch) only after 8-10 years of age. Before this age the more accurate sense teaches (calibrates) the others; when one calibrating modality is missing, the other modalities result impaired. Children with visual disability have problems in understanding the haptic or auditory perception of space and children with motor disabilities have problems in understanding the visual dimension of objects. This review presents our recent studies on multisensory integration and cross-sensory calibration in children and adults with and without sensory and motor disabilities. The goal of this review is to show the importance of interaction between sensory systems during the early period of life in order to correct perceptual development to occur.

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

    2012-06-01

    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.

    Full Text Available Background and Aim: Recently, researchers have increasingly turned to study the relation between stuttering and syntactic complexity. This study investigates the effect of syntactic complexity on theamount of speech dysfluency in stuttering Persian-speaking children and adults in conversational speech. The obtained results can pave the way to a better understanding of stuttering in children andadults, and finding more appropriate treatments.Methods: In this cross-sectional study, the participants were 15 stuttering adult Persian-speakers, older than 15 years, and 15 stuttering child Persian-speakers of 4-6 years of age. In this study, first a 30 minute sample of the spontaneous speech of the participants was provided. Then the utterances of each person were studied in respect to the amount of dysfluency and syntactic complexity. The obtained information was analyzed using paired samples t-test.Results: In both groups of stuttering children and adults, there was a significant difference between the amount of dysfluency of simple and complex sentences (p<0.05.Conclusion: The results of this study showed that an increase in syntactic complexity in conversational speech, increased the amount of dysfluency in stuttering children and adults. Moreover,as a result of increase of syntactic complexity, dysfluency had a greater increase in stuttering children than stuttering adults.

    Stops at the end of Korean words are always unreleased. The question addressed here was whether Korean adults and children living in the U.S. can learn to release stops at the end of English words. Four groups of 18 native Koreans (NK) who differed according to age (adult versus child) and length of residence in the U.S. (3 vs 5 years at T1) participated. Two native English (NE) groups served as age-matched controls. Production data were collected at two times (T1, T2) separated by one year. English words ending in /t/ and /k/ were then examined in perception experiments (Exp. 1, Exp. 2). NE-speaking judges decided whether the final stop has a release burst or not. Exp. 1 showed that NE talkers released /t/ more often than NK talkers did. The effect of time was also significant. Talkers produced release bursts more often at T2 than at T1. Exp. 2 showed that, unlike Exp. 1, there were significant differences between NK adults and children. While NK children did not differ from NE children, NK adults released the final /k/ much less often than NE adults did. Possible reasons for why the expected children's advantage was seen for /k/, but not for /t/, will be discussed. [Work supported by NIH.

    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.

    Belgium, and especially the northern region called Flanders, has been a center of expertise in cochlear implants and early hearing screening for many years. Some of their surgeons and engineers were pioneers in the development of cochlear implants and in 1998 Flanders was the first region in Europe to implement a universal hearing screening program for all neonates. The Belgian National Institute for Health and Disability Insurance has reimbursed cochlear implants in children and adults since 1994 and bilateral implantation in children under the age of 12 years since February 2010. These deaf children, screened and implanted early, achieve higher auditory, speech and language outcomes and increasing numbers are going to regular schools using fewer interpreters. In 2010, 93% of severe-to-profound deaf preschool children in Flanders had received cochlear implants and 25% had bilateral implants. Although on average twice as many adults as children are implanted a year in Belgium, we have less research data available from this adult population. Also very little is published about the growth curves and minimal rehabilitation requirements (intensity, duration etc.) after implantation for both children and adults. So, there still remain many challenges for the future.

    This study prospectively investigates associations between youth moderate-to-vigorous-intensity physical activity (MVPA) and body composition in young adult women using data from the Dietary Intervention Study in Children (DISC) and the DISC06 Follow-Up Study. MVPA was assessed by questionnaire on 5 occasions between the ages 8 and 18 years and at age 25-29 years in 215 DISC female participants. Using whole body dual-energy x-ray absorptiometry (DXA), overall adiposity and body fat distribution were assessed at age 25-29 years by percent body fat (%fat) and android-to-gynoid (A:G) fat ratio, respectively. Linear mixed effects models and generalized linear latent and mixed models were used to assess associations of youth MVPA with both outcomes. Young adult MVPA, adjusted for other young adult characteristics, was significantly inversely associated with young adult %fat (%fat decreased from 37.4% in the lowest MVPA quartile to 32.8% in the highest (p-trend = 0.02)). Adjusted for youth and young adult characteristics including young adult MVPA, youth MVPA also was significantly inversely associated with young adult %fat (β=-0.40 per 10 MET-hrs/wk, p = .02) . No significant associations between MVPA and A:G fat ratio were observed. Results suggest that youth and young adult MVPA are important independent predictors of adiposity in young women.

    The hypothesis tested was that stutterers subvocalize more slowly than nonstutterers and that they need more time for the overt production of the fluent parts of their speech. We also investigated whether rate differences could only be observed for those words on which the stutterers expect to stutter. Fifty-nine school children (27 stutterers and 32 nonstutterers) and 19 adults (18 stutterers and 21 nonstutterers) performed a reading task in which a noun was presented together with its definite article. The presentation times of the reading material were controlled by the subjects. Half of the material had to be read silently, the other half orally. In oral reading, only the data from those trials without any indication of disfluencies were used. Dependent variables were presentation times, speech latency, and speech duration. The stutterers' silent presentation times were significantly longer than those of nonstutterers and this difference was significantly greater for children than for adults. In oral reading all stutterers, regardless of age, had longer presentation times, speech latencies, and article durations than the nonstutterers. Some nouns, however, were uttered significantly more rapidly by stutterers than by nonstutterers. These time differences were found to be independent of the stutterers' expectation to stutter. Our results indicate that a strictly motoric explanation of stuttering is inadequate. The data show that the stutterers and nonstutterers differ with respect to the temporal parameters not only during speech execution, but during speech planning as well.

    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.

    2014-06-15

    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.

    Recent studies have indicated that people have a strong tendency to compare fractions based on constituent numerators or denominators. This is called componential processing. This study explored whether componential processing was preferred in tasks involving high stimuli variability and high contextual interference, when fractions could be compared based either on the holistic values of fractions or on their denominators. Here, stimuli variability referred to the fact that fractions were not monotonous but diversiform. Contextual interference referred to the fact that the processing of fractions was interfered by other stimuli. To our ends, three tasks were used. In Task 1, participants compared a standard fraction 1/5 to unit fractions. This task was used as a low stimuli variability and low contextual interference task. In Task 2 stimuli variability was increased by mixing unit and non-unit fractions. In Task 3, high contextual interference was created by incorporating decimals into fractions. The RT results showed that the processing patterns of fractions were very similar for adults and children. In task 1 and task 3, only componential processing was utilzied. In contrast, both holistic processing and componential processing were utilized in task 2. These results suggest that, if individuals are presented with the opportunity to perform componential processing, both adults and children will tend to do so, even if they are faced with high variability of fractions or high contextual interference.

    2010-08-01

    In four experiments with 4-, 6-, and 9-year-old children and adults, the hypothesis was tested that, all other conditions being equal, a novel and unusual event elicits stronger curiosity and exploratory behaviour if its suggested explanation involves an element of the supernatural than if it does not (the impossible over possible effect - the I/P effect). Participants were shown an unusual phenomenon (a spontaneous disintegration of a physical object in an apparently empty box) framed in the context of either a magical (the impossible event) or scientific (the possible event) explanation. In the verbal trial, participants showed a clear understanding of the difference between the effect of genuine magic and the effect of a trick. In the behavioural trial, both children and adults showed the I/P effect. They were more likely to run the risk of losing their valuable objects in order to explore the impossible event than the possible event. Follow-up experiments showed that the I/P effect couldn't be explained as an artifact of the different degrees of cost of exploratory behaviour in the possible and impossible conditions or as a result of misinterpreting magic as tricks. The I/P effect emerged when the cost of exploratory behaviour was moderate and disappeared when the cost was perceived as too high or too low.

    production of interleukin IL-6, tumour necrosis factor alpha (TNF alpha) and interferon gamma (IFNg) in neonates, children and adults. In cultures without added polyclonal activators IL-6 and TNF alpha levels in children were 3-6 times higher than those of umbilical cords and adults. However, using optimal...... production could be ascribed to differences in the frequency of monocytes, T cells or B cells. The TNF alpha levels in suboptimally stimulated cultures correlated negatively with the expression of LFA-3 and positively with CD45RA, while IFNg correlated positively with CD2, LFA-1, CD45R0 and CD8....... In conclusion, the study provides evidence of age related differences in the production of TNF alpha, IL-6 and IFNg among neonates, children and adults. These differences may to some extent be caused by differences in the expression of cell surface molecules involved in cellular interactions and signalling....

    The present study examined the effect of agonist activation and antagonist co-activation on the shape of the knee extension moment-angle relationship in adults and children. Isometric knee extension maximum voluntary contractions (MVCs) were performed at every 5 degrees of knee flexion between 55 degrees and 90 degrees (full extension = 0 degrees) by ten men, ten women, ten boys and ten girls. For each trial, the knee extensors' voluntary activation level was quantified using magnetic stimulation and the level of antagonist co-activation was quantified from their electromyographical activity. Peak MVC moment was greater for men (264 +/- 63 N m) than women (177 +/- 60 N m), and greater for adults than children (boys 78 +/- 17 N m, girls 91 +/- 28 N m) (p architecture, and the pattern of the moment arm-angle relationship may in combination occur so that as children develop and mature into adults the shape of the moment-angle relationship is not altered.

    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.

    Objective Corner stores, also known as bodegas, are prevalent in low-income urban areas and primarily stock high-energy foods and beverages. Little is known about individual-level purchases in these locations. The purpose of the present study was to assess corner store purchases (items, nutritional characteristics and amount spent) made by children, adolescents and adults in a low-income urban environment. Design Evaluation staff used 9238 intercept surveys to directly examine food and beverage purchases. Setting Intercepts were collected at 192 corner stores in Philadelphia, PA, USA. Subjects Participants were adult, adolescent and child corner store shoppers. Results Among the 9238 intercept surveys, there were 20 244 items. On average, at each corner store visit, consumers purchased 2·2 (SD 2·1) items (1·3 (SD 2·0) foods and 0·9 (SD 0·9) beverages) that cost $US 2·74 (SD $US 3·52) and contained 2786·5 (SD 4454·2) kJ (666·0 (SD 1064·6) kcal). Whether the data were examined as a percentage of total items purchased or as a percentage of intercepts, the most common corner store purchases were beverages, chips, prepared food items, pastries and candy. Beverage purchases occurred during 65·9 % of intercepts and accounted for 39·2 % of all items. Regular soda was the most popular beverage purchase. Corner store purchases averaged 66·2 g of sugar, 921·1mg of sodium and 2·5 g of fibre per intercept. Compared with children and adolescents, adults spent the most money and purchased the most energy. Conclusions Urban corner store shoppers spent almost $US 3·00 for over 2700 kJ (650 kcal) per store visit. Obesity prevention efforts may benefit from including interventions aimed at changing corner store food environments in low-income, urban areas. PMID:25115817

    2004-08-01

    This study examined the on-line processing of French sentences in a grammaticality judgment experiment. Three age groups of French children (mean age: 6 ; 8, 8 ; 6 and 10 ; 10 years) and a group of adults were asked to detect grammatical violations as quickly as possible. Three factors were studied: the violation type: agreement violations (number and gender) vs. word order violations; the violation position: early vs. late in the sentence; the target type of the violations: intra vs. interphrasal. An example of an early interphrasal verbal agreement violation follows: 'Chaque semaine la voisine remplissent le frigo après avoir fait les courses au marché' (Every week the neighbour fill the fridge after shopping at the market). The main developmental results were the following: not surprisingly, children were always slower than adults in the detection of grammatical violations. At each age level, morphological violations were more rapidly detected than word order violations. Each age group was faster at judging sentences with later occurring violations and the position effect was especially strong in the youngest groups. Finally, intraphrasal violations were more rapidly detected than interphrasal ones, this effect being observed only in the oldest groups (i.e. 10 ; 10 years and adults). The results were compared to previous on-line data obtained in modern Greek (Kail & Diakogiorgi, 1998) showing strong similarities, even though Greek is a very rich morphological language. These results are discussed within the framework of the Competition Model, outlining the necessity to incorporate new processing constraints into the model.

  16. Visual stimulus parameters seriously compromise the measurement of approximate number system acuity and comparative effects between adults and children

    Directory of Open Access Journals (Sweden)

    Denes eSzucs

    2013-07-01

    Full Text Available It has been suggested that a simple non-symbolic magnitude comparison task is sufficient to measure the acuity of a putative Approximate Number System (ANS. A proposed measure of the ANS, the so-called 'internal Weber fraction' (w, would provide a clear measure of ANS acuity. However, ANS studies have never presented adequate evidence that the visual stimulus parameters did not compromise measurements of w to such extent that w is actually driven by visual instead of numerical processes. We therefore investigated this question by testing non-symbolic magnitude discrimination in seven-year-old children and adults. We controlled for visual parameters in a more stringent manner than usual. As a consequence of these controls, in some trials numerical cues correlated positively with number while in others they correlated negatively with number. This congruency effect strongly correlated with w, which means that congruency effects were probably driving effects in w. Consequently, in both adults and children congruency had a major impact on the fit of the model underlying the computation of w. Furthermore, children showed larger congruency effects than adults. This suggests that ANS tasks are seriously compromised by the visual stimulus parameters, which cannot be controlled. Hence, they are not pure measures of the ANS and some putative w or ratio effect differences between children and adults in previous ANS studies may be due to the differential influence of the visual stimulus parameters in children and adults. In addition, because the resolution of congruency effects relies on inhibitory (interference suppression function, some previous ANS findings were probably influenced by the developmental state of inhibitory processes especially when comparing children with developmental dyscalculia and typically developing children.

  17. Circumstances and factors associated with accidental deaths among children, adolescents and young adults in Cuiaba, Brazil

    Christine Baccarat de Godoy Martins

    Full Text Available CONTEXT AND OBJECTIVE Analysis on accidents from the perspective of population segments shows there is higher incidence among children, adolescents and young adults. Since the characteristics and circunstances of the event are closely related to educational, economic, social and cultural issues, identifying them may contribute towards minimizing the causes, which are often fatal. The aim here was to identify the environmental, chemical, biological and cultural factors associated with deaths due to accidents among children, adolescents and young adults in Cuiabá, in 2009. DESIGN AND SETTING This was a descriptive cross-sectional study conducted in Cuiabá, Mato Grosso, Brazil. RESULTS Thirty-nine accidental deaths of individuals aged 0 to 24 years were examined: 56.4% due to traffic accidents; 25.6%, drowning; 10.3%, aspiration of milk; 5.1%, falls; and 2.6%, accidentally triggering a firearm. Male victims predominated (82.1%. The presence of chemical, environmental and biological risk factors was observed in almost all of the homes. Regarding cultural factors and habits, a large proportion of the families had no idea whether accidents were foreseeable events and others did not believe that the family's habits might favor their occurrence. Delegation of household chores or care of younger siblings to children under the age of 10 was common among the families studied. CONCLUSION The results point towards the need to have safe and healthy behavioral patterns and environments, and to monitor occurrences of accidents, thereby structuring and consolidating the attendance provided for victims.

    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.

    Magnetic resonance imaging (MRI) is considered the imaging standard for diagnosis and characterization of perianal complications associated with Crohn disease in children and adults. To define MRI criteria that could act as potential predictors of treatment response in fistulizing Crohn disease in children, in order to guide more informed study interpretation. We performed a retrospective database query to identify all children and young adults with Crohn disease who underwent serial MRI studies for assessment of perianal symptoms between 2003 and 2010. We examined imaging features of perianal disease including fistula number, type and length, presence and size of associated abscess, and disease response/progression on follow-up MRI. We reviewed imaging studies and electronic medical records. Statistical analysis, including logistic regression, was performed to associate MR imaging features with treatment response and disease progression. We included 36 patients (22 male, 14 female; age range 8-21 years). Of these, 32 had a second MRI exam and 4 had clinical evidence of complete response, obviating the need for repeat imaging. Of the parameters analyzed, presence of abscess, type of fistula according to the Parks classification, and multiplicity were not predictors of treatment outcome. Maximum length of the dominant fistula and aggregate fistula length in the case of multiple fistulae were the best predictors of treatment outcome. Maximum fistula length <2.5 cm was a predictor of treatment response, while aggregate fistula length ≥2.5 cm was a predictor of disease progression. Perianal fistula length is an important imaging feature to assess on MRI of fistulizing Crohn disease. (orig.)

    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.

  1. Reweighting of sensory inputs to control quiet standing in children from 7 to 11 and in adults.

    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.

  2. Experiences from Cochlear Implantation and Auditory Brainstem Implantation in Adults and Children : Electrophysiological Measurements, Hearing Outcomes and Patient Satisfaction

    Cochlear implants (CIs) and auditory brainstem implants (ABIs) are prostheses for hearing used in patients with profound hearing impairment. A CI requires an operational cochlear nerve to function in contrast to an ABI. ABIs were initially designed for adult patients with neurofibromatosis type 2 (NF2), suffering from bilateral vestibular schwannomas. Now ABIs are also used for patients, both adults and children, with congenital cochlear malformations, cochlear nerve hypoplasia/aplasia, and c...

    The extent to which verbal (VM) and visuospatial memory (VSM) tests measure the same or multiple constructs is unclear. Likewise the relationship between VM and VSM across development is not known. These questions are addressed using genetically informative data, studying two age cohorts (young adults and children) of twins and siblings. VM and VSM were measured in the working memory and short-term memory domain. Multivariate genetic analyses revealed that two highly correlated common genetic factors, one for VM and one for VSM, gave the best description of the covariance structure among the measures. Only in children, specific genetic factors were also present. This led to the following conclusions: In children, one genetic factor is responsible for linking VM and VSM. Specific genetic factors create differences between these two domains. During the course of development, the influence of genetic factors unique to each of these domains disappears and the genetic factor develops into two highly correlated factors, which are specific to VM and VSM respectively. At the environmental level, in both age cohorts, environmental factors create differences between these domains.

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

    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.

  5. The spacing effect in intentional and incidental free recall by children and adults: Limits on the automaticity hypothesis.

    Preschoolers, elementary school children, and college students exhibited a spacing effect in the free recall of pictures when learning was intentional. When learning was incidental and a shallow processing task requiring little semantic processing was used during list presentation, young adults still exhibited a spacing effect, but children consistently failed to do so. Children, however, did manifest a spacing effect in incidental learning when an elaborate semantic processing task was used. These results limit the hypothesis that the spacing effect in free recall occurs automatically and constrain theoretical accounts of why the spacing between repetitions affects recall performance.

    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. Regression analysis revealed that the degree of improvement on the Average Change of the PGI-R was strongly associated with several biomarkers (adj.

    Used standardized questionnaires to compare psychosocial functioning of 116 children and adolescents (9 to 18 years) and 73 adults (18 to 38 years) operated on for hypospadias, a congenital penile anomaly, with that of 88 and 50 age-matched comparison males, respectively, treated for an inguinal hernia. The relationships of coping with penile appearance, subject age, severity of hypospadias, number of operations, age at final surgery, and type of surgical procedure with psychosocial functioning were also investigated. Hypospadias patients did not exhibit a poorer psychosocial functioning and no significant relationships of various medical characteristics with psychosocial functioning could be discerned. Genital/body perception of hypospadias patients ages 9 to 18 years correlated positively with psychosocial functioning, albeit with low values. These findings are important for psychologists and specialists in the counseling process of hypospadias patients and their parents.

    Hinz, L D

    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.

    The relationship between urinary homovanillic acid (HVA), vanillylmandelic acid (VMA) and creatinine is investigated and reference ranges are constructed for HVA and VMA. A total of 769 urine samples were obtained from children and adults. The ratios HVA/creatinine and VMA/creatinine were highly correlated with creatinine concentration; hence, reference to creatinine was found to be an inappropriate adjustment for urinary dilution. An alternative method based upon linear regression is proposed. After allowing for differing levels of creatinine, HVA and VMA were found to be significantly correlated with age, height and weight for individuals aged less than 20 years. In those aged over 20 years, HVA was significantly correlated with weight and VMA with age. Differences between sexes were found in the levels of HVA and VMA, the exception being VMA in the over 20 age group. Reference ranges were constructed for HVA and VMA which are variously dependent upon creatinine, age, sex and weight.

    Full Text Available Background and Objective. Environmental factors are an increasing concern for respiratory health in developing countries. The objective of this study was to investigate whether Nigerien people living in cultivated areas have more respiratory symptoms than those living in pastoral areas. Method. A cross-sectional study was conducted in 2013 in two populations during the rainy season when land is cultivated. Environmental factors including pesticide use and respiratory symptoms were collected in adults and children during face-to-face interviews. Multivariate analysis between exposures and symptoms was performed in children and in adults separately. Results. The study included 471 adults and 229 children. Overall, none of the households reported the use of pesticides for agricultural purposes. However, 87.2% reported the use of insecticides at home. Multivariate analysis showed that people living in agricultural areas compared to those in pastoral areas had an increased risk of respiratory symptoms in adults (wheezing, dyspnea, sudden shortness of breath, and cough without fever and in children (cough without fever. The use of insecticides showed no effect on respiratory symptoms after adjustment. Conclusion. This first epidemiological study on the environment and respiratory health conducted in Niger demonstrates a significant relationship between respiratory manifestations and the agricultural characteristics of the living area. However only the effect of insecticides in the home on respiratory health was observed.

    Full Text Available Background: The skeletal morphology of the temporo-mandibular joint (TMJ is constantly remodeled. Aims and Objectives: A comparative study was undertaken to determine and characterize the differences in the skeletal morphology of TMJ of children and adults. Materials and Methods: The study was conducted on 30 children cadavers and 30 adult volunteers. Parameters that could reflect TMJ skeletal morphology were measured with a new technology combining helical computed tomography (CT scan with multi-planar reformation (MPR imaging. Results: Significant differences between children cadavers and adults were found in the following parameters ( P < 0.05: Condylar axis inclination, smallest area of condylar neck/largest area of condylar process, inclination of anterior slope in inner, middle, and outer one-third of condyle, anteroposterior/mediolateral dimension of condyle, length of anterior slope/posterior slope in inner and middle one-third of condyle, anteroposterior dimension of condyle/glenoid fossa, mediolateral dimension of condyle/glenoid fossa, inclination of anterior slope of glenoid fossa, depth of glenoid fossa, and anteroposterior/mediolateral dimension of glenoid fossa. Conclusion: There are significant differences of TMJ skeletal morphology between children and adults.

    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.

    Concerns about vitamin D status in the United States have resurfaced due to increasing reports of insufficiency and deficiency. Few foods contain vitamin D naturally, and currently few foods are fortified in the United States. Intakes of vitamin D in the United States from food and food plus supplements by age, sex, and race/ethnicity group were estimated. Individuals > or = 1 y old who participated in the 1999-2000 National Health and Nutrition Examination Survey (NHANES 1999-2000) were included in the analysis. Vitamin D intake by non-Hispanic (NH) white, NH black, Mexican American, and all individuals in the United States was estimated and compared with recommended levels. Vitamin D intakes were highest among children and teenagers, and lowest in the oldest age categories. Among children age 1-8 y, adequate intake (AI) levels for vitamin D from food were met or exceeded by 69% of Mexican American, 59% of NH white, and 48% of NH black subpopulations. Among adults > or = 51 y old, only 4% met or exceeded the AI from food alone. Few women 19-50 y old or men and women > or = 51 y old were estimated to consume recommended vitamin D levels from food. Mean dietary intakes of vitamin D from food plus supplements were consistently highest among NH white populations, although only small proportions of all those > or = 51 y old had intakes above the recommended levels. The large discrepancy between vitamin D intake by older individuals from food plus supplements and recommended levels, especially for NH black and Mexican American adults, warrants intervention.

    Combining {sup 18}F-FDG PET with whole-body MR for paediatric cancer staging is practically feasible if imaging protocols can be streamlined. We compared {sup 18}F-FDG PET/STIR with accelerated {sup 18}F-FDG PET/FSPGR for whole-body tumour imaging in children and young adults. Thirty-three children and young adults (17.5 ± 5.5 years, range 10-30) with malignant lymphoma or sarcoma underwent a {sup 18}F-FDG PET staging examination, followed by ferumoxytol-enhanced STIR and FSPGR whole-body MR. {sup 18}F-FDG PET scans were fused with MR data and the number and location of tumours on each integrated examination were determined. Histopathology and follow-up imaging served as standard of reference. The agreement of each MR sequence with the reference and whole-body imaging times were compared using Cohen's kappa coefficient and Student's t-test, respectively. Comparing {sup 18}F-FDG PET/FSPGR to {sup 18}F-FDG PET/STIR, sensitivities were 99.3 % for both, specificities were statistically equivalent, 99.8 versus 99.9 %, and the agreement with the reference based on Cohen's kappa coefficient was also statistically equivalent, 0.989 versus 0.992. However, the total scan-time for accelerated FSPGR of 19.8 ± 5.3 minutes was significantly shorter compared to 29.0 ± 7.6 minutes for STIR (p = 0.001). F-FDG PET/FSPGR demonstrated equivalent sensitivities and specificities for cancer staging compared to {sup 18}F-FDG PET/STIR, but could be acquired with shorter acquisition time. (orig.)

    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.

    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 long-term biokinetics and dosimetry of carbon-14 were studied in nine adults and eight children undergoing carbon-14 urea breath test for Helicobacter pylori (HP) infection. The elimination of {sup 14}C via exhaled air and urine was measured with the liquid scintillation counting technique and with accelerator mass spectrometry. After the subjects had been given 110 kBq {sup 14}C-urea (children: 55 kBq) orally, samples of exhaled air were taken up to 180 days after administration and samples of urine were collected up to 40 days. Sixteen of the subjects were found to be HP-negative. In these subjects a total of 91.1%{+-}3.9% (mean of adults and children {+-} standard error of the mean) of the administered {sup 14}C activity was recovered. The majority of the administered activity, 88.3%{+-}6.2% in adults and 87.7%{+-}5.0% in children, was excreted via the urine within 72 h after administration. A smaller fraction was exhaled. In adults 4.6%{+-}0.6% of the activity was exhaled within 20 days and in children 2.6%{+-}0.3%. Uncertainties in the biokinetic results are mainly due to assumptions concerning endogenous CO{sub 2} production and urinary excretion rate and are estimated to be less than 30%. The absorbed dose to various organs and the effective dose were calculated using the ICRP model for urea and CO{sub 2}. The urinary bladder received the highest absorbed dose: in adults, 0.15{+-}0.01 mGy/MBq and in children of various ages (7-14 years), 0.14-0.36 mGy/MBq. The findings indicate that an investigation with {sup 14}C-urea gives an effective dose to adults of 2.1{+-}0.1 {mu}Sv (for 110 kBq) and to children of 0.9-2.5 {mu}Sv (for 55 kBq). From a radiation protection point of view, there is thus no reason for restrictions on even repeated screening investigations with {sup 14}C-urea in whole families, including children. (orig.)

    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

  4. 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.

  5. Children's Increased Emotional Egocentricity Compared to Adults Is Mediated by Age-Related Differences in Conflict Processing.

    This study investigated the cognitive mechanisms underlying age-related differences in emotional egocentricity bias (EEB) between children (aged 7-12 years, n = 30) and adults (aged 20-30 years, n = 30) using a novel paradigm of visuogustatory stimulation to induce pleasant and unpleasant emotions. Both children and adults showed an EBB, but that of children was larger. The EEB did not correlate with other measures of egocentricity. Crucially, the developmental differences in EEB were mediated by age-related changes in conflict processing and not visual perspective taking, response inhibition, or processing speed. This indicates that different types of egocentricity develop independently of one another and that the increased ability to overcome EEB can be explained by age-related improvements in conflict processing.

    The overall purpose of the study was to examine if individuals with low motor competence achieve age-adequate fitness and health. A group of 149 children, adolescents, and adults with low or high motor competence participated in motor, fitness, and health assessments. Individuals with low motor competence did not differ on their basic physiological health parameters, but they had less optimal levels of overall health and fitness indices than those with high motor competence. As a function of age, musculoskeletal fitness was significantly compromised for the low motor competence group. The metabolic indices suggested that the low motor competence group had significantly higher BMI's compared to the high motor competence group. Motor skills and static balance were significant predictors of the BMI. Exercise intensity differed between children in the low and high motor competence group. The findings suggest that individuals with low motor competence have compromised health-related fitness. In order to discriminate between individuals with high and low motor competence, fitness assessment should include at least back extension, curl ups, and sit and reach. In addition, health-related fitness measurements such as BMI, waist circumference, blood lipid profile and bone mineral density are also recommended.

    This study evaluated the effectiveness of the Adults and Children Together (ACT) Against Violence Parents Raising Safe Kids program, developed by the American Psychological Association in collaboration with the National Association for the Education of Young Children, as an economical primary prevention intervention for child maltreatment. Using an experimental design with random assignment to groups, program impact on participating parents' knowledge, behavior, and attitudes compared to those of a comparison group of parents receiving standard community-based support services was examined. As hypothesized, the ACT Parents Raising Safe Kids program achieved positive results in several areas related to effective parenting, including a reduction in the use of harsh verbal and physical discipline and an increase in nurturing behavior. Positive results were observable both at the conclusion of the ACT program and at three-month follow-up. Results further indicated a positive impact on parent expectations and social support for those parents with the greatest need in these areas. Qualitative data collected through focus groups demonstrated that parents themselves perceived numerous benefits to the ACT program, including assistance in controlling their anger, learning and implementing better parenting and discipline strategies, and recognizing when their child's behavior is developmentally appropriate. Overall, findings suggest that the ACT Parents Raising Safe Kids program is a promising primary prevention strategy that can be implemented across diverse community settings.

    When participants carry out visually presented digit serial recall, their performance is better if they are given the opportunity to encode extra visuospatial information at encoding-a phenomenon that has been termed visuospatial bootstrapping. This bootstrapping is the result of integration of information from different modality-specific short-term memory systems and visuospatial knowledge in long term memory, and it can be understood in the context of recent models of working memory that address multimodal binding (e.g., models incorporating an episodic buffer). Here we report a cross-sectional developmental study that demonstrated visuospatial bootstrapping in adults (n=18) and 9-year-old children (n=15) but not in 6-year-old children (n=18). This is the first developmental study addressing visuospatial bootstrapping, and results demonstrate that the developmental trajectory of bootstrapping is different from that of basic verbal and visuospatial working memory. This pattern suggests that bootstrapping (and hence integrative functions such as those associated with the episodic buffer) emerge independent of the development of basic working memory slave systems during childhood.

    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.

    Objectives: To provide age- and sex-specific reference data for mechanography-derived parameters of muscle function in Canadian children and youth using the single two-legged jump (S2LJ) with hands-on-waist. Methods: Our sample included 2017 observations from 715 participants (9-21 years; 338 girls). Participants performed three S2LJ with hands-on-waist on a force platform (Leonardo Mechanograph, Novotec). Outcomes were maximum peak power (Pmax), Pmax /mass, peak force/body weight (Fmax /BW), force efficiency, maximum jump height (Hmax), and velocity (Vmax). We used the LMS method to construct age- and sex-specific percentile curves and mixed effects models to examine sex and ethnic differences. Results: With the exception of Efficiency, mechanography outcomes were greater in girls (4-40%, padolescence (age 11-13 years; 3-65%, p<0.05) and persisted into young adulthood, except for Fmax/BW which was not greater in boys until age 17 (4-10%, p<0.05). Mechanography outcomes were 3-9% (p<0.05) greater in Asian compared with white participants. Conclusions: We provide the first reference data for the S2LJ using the hands-on-waist protocol in children, youth and young adults. These data support previous findings using freely moving arms and can be used when evaluating muscle function in pediatric studies. PMID:27973380

    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.

    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

  13. Sexual dimorphism in tuberculosis incidence: children cases compared to adult cases in Tuscany from 1997 to 2011.

    Full Text Available BACKGROUND: In most countries, men seem to be more susceptible to tuberculosis (TB than women, but only few studies have investigated the reasons of this gender incidence difference. The effect of sexual hormones on immunity is possible. METHODS: Data from children and adults, living in Tuscany, hospitalized for TB in all the thirty-one regional hospitals from January 1st 1997 to December 31st 2011, were analyzed using the International Classification of Disease, 9th Revision, Clinical Modification. RESULTS: During the study period, 10,744 patients were hospitalized with TB diagnosis, precisely 279 (2.6% children [0-14 years], 205 (1.9% adolescents [15-18 years] and 10,260 (95.5% adults [≥ 18 years]. The male population ranged from 249 patients (51.4% in children and adolescents, to 6,253 (60.9% in adults. Pulmonary TB was the most common form both in children and adults. Men were more likely than women to have pulmonary TB after puberty, while no significant differences were found between males and females in the hospitalized children. The male gender also resulted the most affected for the extra-pulmonary disease sites, excluding the lymphatic system, during the reproductive age. CONCLUSIONS: Our findings suggest a possible role of sexual hormones in the development of TB. No significant male-female difference was found in TB incidence among children, while a sex ratio significantly different from 1:1 emerged among reproductive age classes. An increased incidence difference also persisted in older men, suggesting that male-biased risk factors could influence TB progression. Some limitations of the study are the sample size, the method of discharge diagnosis which could be deficient in accuracy in some cases, the increasing number of immigrants and the lack of possible individual risk factors (smoke and alcohol. Further studies are needed to investigate the possible hormone-driven immune mechanisms determining the sexual dimorphism in TB.

    Background The epidemiologic characteristics of children and young adults with acute kidney injury have been described in single-center and retrospective studies. We conducted a multinational, prospective study involving patients admitted to pediatric intensive care units to define the incremental risk of death and complications associated with severe acute kidney injury. Methods We used the Kidney Disease: Improving Global Outcomes criteria to define acute kidney injury. Severe acute kidney injury was defined as stage 2 or 3 acute kidney injury (plasma creatinine level ≥2 times the baseline level or urine output <0.5 ml per kilogram of body weight per hour for ≥12 hours) and was assessed for the first 7 days of intensive care. All patients 3 months to 25 years of age who were admitted to 1 of 32 participating units were screened during 3 consecutive months. The primary outcome was 28-day mortality. Results A total of 4683 patients were evaluated; acute kidney injury developed in 1261 patients (26.9%; 95% confidence interval [CI], 25.6 to 28.2), and severe acute kidney injury developed in 543 patients (11.6%; 95% CI, 10.7 to 12.5). Severe acute kidney injury conferred an increased risk of death by day 28 after adjustment for 16 covariates (adjusted odds ratio, 1.77; 95% CI, 1.17 to 2.68); death occurred in 60 of the 543 patients (11.0%) with severe acute kidney injury versus 105 of the 4140 patients (2.5%) without severe acute kidney injury (P<0.001). Severe acute kidney injury was associated with increased use of mechanical ventilation and renal-replacement therapy. A stepwise increase in 28-day mortality was associated with worsening severity of acute kidney injury (P<0.001 by log-rank test). Assessment of acute kidney injury according to the plasma creatinine level alone failed to identify acute kidney injury in 67.2% of the patients with low urine output. Conclusions Acute kidney injury is common and is associated with poor outcomes, including increased

    The first single function myoelectric prosthetic hand was introduced in the 1960's. This hand was controlled by the electric fields generated by muscle contractions in the residual limb of the amputee user. Electrodes and amplifiers, embedded in the prosthetic socket, measured these electric fields across the skin, which increase in amplitude as the individual contracts their muscle. When the myoelectric signal reached a certain threshold amplitude, the control unit activated a motor which opened or closed a hand-like prosthetic terminal device with a pincher grip. Late in the 1990's, little has changed. Most current myoelectric prostheses still operate in this same, single-function way. To better understand the limitations of the current single-function myoelectric hand and the needs of those who use them, The Institute for Rehabilitation and Research (TIRR), sponsored by the National Institutes of Health (NUH), surveyed approximately 2,500 individuals with upper limb loss [1]. When asked to identify specific features of their current myoelectric prostheses that needed improvement, the survey respondents overwhelmingly identified the lack of wrist and finger movement, as well as poor control capability. However, simply building a mechanism with individual finger and wrist motion is not enough. In the 1960's and 1970's, engineers built a number of more dexterous prosthetic hands. Unfortunately, these were rejected during clinical trials due to a difficult and distracting control interface. The goal of this project, "Applying Space Technology to Enhance Control of an Artificial Arm for Children and Adults with Amputations," was to lay the foundation for a multi-function, intuitive myoelectric control system which requires no conscious thought to move the hand. We built an extensive myoelectric signal database for six motions from ten amputee volunteers, We also tested a control system based on new artificial intelligence techniques on the data from two of these

    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.

    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

    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.

    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 Tinea capitis is a dermatophyte infection that occurs mainly in childhood; there are few reports, in Brazil, in adolescents and adults. The detection of asymptomatic carriers is of great importance in the disease control. From February 1998 to February 1999, a study was performed at the outpatient Dermatologic Unit of Instituto de Puericultura e Pediatria Martagão Gesteira (Universidade Federal do Rio de Janeiro, Brasil to verify the frequency of asymptomatic carriers and tinea capitis between 79 adolescents, adults and elderly who lived in the same household of 56 children (0-12 years with tinea capitis. Of these, one female and one male adults (2.5% were asymptomatic carriers and the cultures revealed Trichophyton tonsurans and Microsporum canis respectively. One female adolescent and two female adults (3.8% had tinea capitis and all cultures revealed Trichophyton tonsurans. The study has shown that adolescents and adults who live in the same household of children with tinea capitis may be sick or asymptomatic carriers.

    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.

    This is the first multicenter Italian experience with rufinamide as an adjunctive drug in children, adolescents and adults with Lennox-Gastaut syndrome. The patients were enrolled in a prospective, add-on, open-label treatment study from 11 Italian centers for children and adolescent epilepsy care. Forty-three patients (26 males, 17 females), aged between 4 and 34 years (mean 15.9 ± 7.3, median 15.0), were treated with rufinamide for a mean period of 12.3 months (range 3-21 months). Twenty patients were diagnosed as cryptogenic and 23 as symptomatic. Rufinamide was added to the baseline therapy at the starting dose of 10mg/kg body weight, evenly divided in two daily doses and then increased by 10mg/kg approximately every 3 days up to a maximum of 1000 mg/day in children aged ≥4 years with a body weight less than 30 kg. In patients more than 30 kg body weight, rufinamide could be titrated up to 3200 mg/day. After a mean follow-up period of 12.3 months (range 3-21 months), the final mean dose of rufinamide was 33.5mg/kg/24h (range 11.5-60) if combined to valproic acid, and of 54.5mg/kg/24h (range 21.8-85.6) without valproic acid. The response rate (≥50% decrease in countable seizures) was 60.5% (26 of 45 patients) in total; 51.1% experienced a 50-99% reduction in seizure frequency and complete seizure control was achieved in the last 4 weeks follow-up by 9.3% of patients. Two patients (4.7%) had a 25-50% seizure reduction, while seizure frequency remained unchanged in 13 (30.2%) and increased in 2 (4.7%). Reliable data for atypical absence seizures and myoclonic seizures were not available, as these are usually impossible to count. Ten patients (23.2%) reported adverse side effects, while taking rufinamide. They were generally mild and transient and most frequently included vomiting, drowsiness, irritability and loss of appetite. In conclusion, rufinamide as an adjunctive therapy reduced the number of drop attacks and major motor seizures in about 60% of

    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.

    Many children and young adults with cerebral palsy (CP) have diminished bone mineral density (BMD) and a propensity to fracture with minimal trauma. The aim of this study was to identify variables which are routinely assessed as part of standard clinical care and that might be used to identify those individuals with CP who are most likely to have low BMD. One hundred and seven participants (ages 2 years 1 month to 21 years 1 month; mean age 10 years 11 months, SD 4 years 2 months) with moderate to severe spastic CP were assessed in detail. This included gathering clinical data, taking anthropometric measures of growth and nutrition, as well as dual energy X-ray absorptiometry measures of BMD. Seventeen participants were ambulatory with assistance (Gross Motor Function Classification System [GMFCS] level III), and 90 were capable of little or no ambulation even with assistance (26 GMFCS level IV and 64 GMFCS level V). Weight z score proved to be the best predictor of BMD z score. Declining BMD z scores also correlated with increasing age and greater severity of involvement. It can be predicted, with reasonable reliability, that a 10-year-old non-ambulatory child with quadriplegic CP and a 'typical' weight z score of -2 will have a BMD z score that is at best -2. Prior fractures, use of anticonvulsants, and feeding difficulties further reduce predicted BMD.

    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.

    (222)Rn is a radioactive, odorless, and colorless element which has a half-life of 3.83 days. One of (222)Rn main resources are Groundwater (wells, springs, etc.). Hence, the use of groundwater with high concentration of (222)Rn can increase the risk of lung and stomach cancers. Concentration of (222)Rn in tap water of Minab city in two temperatures 5 and 15 ºC was measured by radon meter model RTM1668-2. The effective dose was calculated by equations proposed by UNSCEAR. Geometric mean concentration of (222)Rn in drinking water was found to be 0.78±0.06 and 0.46±0.04 Bq/l at 5 and 15 ̊C (p value222)Rn at 5 and 15 ̊C were estimated 0.0021 and 0.0012mSv/y, respectively. Geometric mean concentration in (222)Rn drinking water and effective dose received from drinking water and inhalation of (222)Rn is lower than WHO and EPA standard limits. Increasing temperature of drinking water will decrease the effective dose received. Annual Effective dose received from inhalation and consumption of (222)Rn in drinking water in children is more than adults.

    Intensive chemotherapy regimens can result in severe toxicities, particularly those that involve the digestive systems, leading to morbidity and mortality in this group of patients. Acute enterocolitis can be a frequent complication. The authors performed a retrospective review or patients treated at their institution to ascertain the prognostic value of the clinical symptoms and signs of acute enterocolitis, the corresponding abdominal ultrasonographic findings, and the impact of previous chemotherapy. Amongst 1159 patients with cancer treated at the Centro Infantil Boldrini from 2003 to 2007, 188 (16.2%) patients had 1 or more episode of enterocolitis. An intestinal wall thickness of >or=3 mm on ultrasound was considered diagnostic of enterocolitis. There were 231 episodes of enterocolitis with a death rate of 11.7%. Previous therapy with cytarabine and the presence of abdominal distention affected survival. An intestinal wall thickness of >or=10 mm in the ultrasonographic examination was associated with greater mortality. In multivariate analysis, age, gender, tumor type, degree of neutropenia, intestinal wall thickness, and number of intestinal segments were not statistically significant difference. In children and young adults with cancer and enterocolitis, the clinical findings of 4 or more symptoms and presence of abdominal distention were associated with higher risk of death. Use of cytarabine and an intestinal wall thickness of >or=10 mm were associated with a higher death rate.

    A prominent theory of speech production proposes that speech segments are largely controlled by reference to an internal model, with minimal reliance on auditory feedback. This theory also maintains that suprasegmental aspects of speech are directly regulated by auditory feedback. Accordingly, if a talker is briefly deprived of auditory feedback speech segments should not be affected, but suprasegmental properties should show significant change. To test this prediction, comparisons were made between speech samples obtained from cochlear implant users who repeated words under two conditions (1) implant device turned ON, and (2) implant switched OFF immediately before the repetition of each word. To determine whether producing unfamiliar speech requires greater reliance on auditory feedback than producing familiar speech, English and French words were elicited from English-speaking subjects. Subjects were congenitally deaf children (n=4) and adventitiously deafened adults (n=4). Vowel fundamental frequency and formant frequencies, vowel and syllable durations, and fricative spectral moments were analyzed. Preliminary data only partially confirm the predictions, in that both segmental and suprasegmental aspects of speech were significantly modified in the absence of auditory feedback. Modifications were greater for French compared to English words, suggesting greater reliance on auditory feedback for unfamiliar words. [Work supported by NIDCD.

    Helicobacter pylori infection is a common health problem related to many gastrointestinal disorders. This study aims to estimate the total and age specific prevalence of Helicobacter Pylori infection in Iran. We systematically reviewed all national and international databases and finally identified 21 studies were eligible for meta-analysis. Each of them were assigned a quality score using STROBE checklist. Due to significant heterogeneity of the results, random effects model was used to estimate the pooled prevalence and 95% confidence interval of Helicobacter Pylori infection. All statistical analyses were performed using STATA. V11 software. The pooled prevalence (95% confidence interval) of Helicobacter Pylori infection among all population, children and adults were estimated as 54% (53%- 55%), 42% (41%- 44%) and 62% (61%- 64%) respectively. Helicobacter Pylori, has infected more than half of Iranian people during the last decade. Preventive strategies as well as taking into account this infection during clinical visits should be emphasized to reduce its transmission and prevalence within the community.

    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.

Consideration is given to duration of therapy, side-effect profile and compliance.

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

    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 Diarrhea is a leading cause of morbidity and mortality globally; yet the overall burden of diarrhea in terms of duration and severity has not been quantified. As improvements in treatment lead to decreases in diarrhea mortality, it is important to understand the substantial impact of diarrhea morbidity on disability among children and adults worldwide. Methods We conducted a systematic review to generate estimates of duration and severity outcomes for individuals 0-59 mos, 5-15 yrs, and ≥ 16 yrs, and for 3 severity indexes: mild, moderate, and severe. Results We estimate that among children under-five, 64.8% of diarrheal episodes are mild, 34.7% are moderate, and 0.5% are severe. On average, mild episodes last 4.3 days, and severe episodes last 8.4 days and cause dehydration in 84.6% of cases. We estimate that among older children and adults, 95% of episodes are mild; 4.95% are moderate; and 0.05% are severe. Among individuals ≥ 16 yrs, severe episodes typically last 2.6 days and cause dehydration in 92.8% of cases. Conclusions Moderate and severe episodes constitute a substantial portion of the total envelope of diarrhea among children under-five (35.2%; about 588 million episodes. Among older children and adults, moderate and severe episodes account for a much smaller proportion of the total envelope of diarrhea (5%, but the absolute number of such episodes is noteworthy (about 21.5 million episodes among individuals ≥ 16 yrs. Hence, the global burden of diarrhea consists of significant morbidity, extending beyond episodes progressing to death.

    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.

    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.

    This meta-analysis evaluated the correlations between C-reactive protein (CRP) and obesity in Chinese adults and children. We searched three Chinese databases [Wanfang, WEIPU, and Chinese National Knowledge Infrastructure (CNKI)] in addition to PubMed. The search was restricted to only Chinese studies published online before January 9, 2013. Data from 28 articles were independently abstracted by two reviewers. The articles' characteristics were abstracted as follows: 1) first author name; 2) year of publication; 3) study population; 4) sample size; 5) sex, age, body mass index (BMI), waist circumference (WC), waist-to-hip ratio (WHR), and CRP level of the study population; 6) Pearson correlation coefficients, Spearman correlation coefficients, or odds ratios between CRP level and obesity. The metaanalysis was conducted to pool the Pearson correlation coefficients using a random-effects model. The pooled Pearson correlation coefficient between CRP and BMI was 0.45 [95% confidence interval (CI): 0.33-0.56] in Chinese adults and 0.46 (95% CI: 0.31-0.62) in Chinese children, and the pooled Pearson correlation coefficient was 0.32 (95% CI: 0.24-0.40) in the general Chinese population and 0.53 (95% CI: 0.42-0.64) in the obese Chinese population. Significant correlation was thus found between CRP and obesity in Chinese adults and children.

    With technological innovation, comprehensive dietary intake data can be collected in a wide range of studies and settings. The Automated Self-Administered 24-h (ASA24) Dietary Assessment Tool is a web-based system that guides respondents through 24-h recalls. The purpose of this paper is to describe lessons learned from five studies that assessed the feasibility and validity of ASA24 for capturing recall data among several population subgroups in Canada. These studies were conducted within a childcare setting (preschool children with reporting by parents), in public schools (children in grades 5–8; aged 10–13 years), and with community-based samples drawn from existing cohorts of adults and older adults. Themes emerged across studies regarding receptivity to completing ASA24, user experiences with the interface, and practical considerations for different populations. Overall, we found high acceptance of ASA24 among these diverse samples. However, the ASA24 interface was not intuitive for some participants, particularly young children and older adults. As well, technological challenges were encountered. These observations underscore the importance of piloting protocols using online tools, as well as consideration of the potential need for tailored resources to support study participants. Lessons gleaned can inform the effective use of technology-enabled dietary assessment tools in research. PMID:28146125

  10. Children and adults minimise activated muscle volume by selecting gait parameters that balance gross mechanical power and work demands.

    Terrestrial locomotion on legs is energetically expensive. Compared with cycling, or with locomotion in swimming or flying animals, walking and running are highly uneconomical. Legged gaits that minimise mechanical work have previously been identified and broadly match walking and running at appropriate speeds. Furthermore, the 'cost of muscle force' approaches are effective in relating locomotion kinetics to metabolic cost. However, few accounts have been made for why animals deviate from either work-minimising or muscle-force-minimising strategies. Also, there is no current mechanistic account for the scaling of locomotion kinetics with animal size and speed. Here, we report measurements of ground reaction forces in walking children and adult humans, and their stance durations during running. We find that many aspects of gait kinetics and kinematics scale with speed and size in a manner that is consistent with minimising muscle activation required for the more demanding between mechanical work and power: spreading the duration of muscle action reduces activation requirements for power, at the cost of greater work demands. Mechanical work is relatively more demanding for larger bipeds--adult humans--accounting for their symmetrical M-shaped vertical force traces in walking, and relatively brief stance durations in running compared with smaller bipeds--children. The gaits of small children, and the greater deviation of their mechanics from work-minimising strategies, may be understood as appropriate for their scale, not merely as immature, incompletely developed and energetically sub-optimal versions of adult gaits.

    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.

    To determine, in a systematic review, the diagnostic accuracy, acceptability and cost-effectiveness of less invasive autopsy by post-mortem MR imaging, in fetuses, children and adults. We searched Medline, Embase, the Cochrane library and reference lists to identify all studies comparing post-mortem MR imaging with conventional autopsy, published between January 1990 and March 2009. 539 abstracts were identified; 15 papers met the inclusion criteria; data from 9 studies were extracted (total: 146 fetuses, 11 children and 24 adults). In accurately identifying the final cause of death or most clinically significant abnormality, post-mortem MR imaging had a sensitivity and specificity of 69% (95% CI-56%, 80%) and 95% (95% CI-88%, 98%) in fetuses, and 28% (95% CI-13%, 47%) and 64% (95% CI-23%, 94%) in children and adults, respectively; however the published data is limited to small, heterogenous and poorly designed studies. Insufficient data is available on acceptability and economic evaluation of post-mortem MR imaging. Well designed, large, prospective studies are required to evaluate the accuracy of post-mortem MR imaging, before it can be offered as a clinical tool.

    This work describes in vitro measurement of the total pressure loss at varying flow rate through anatomically realistic conducting airway replicas of 10 children, 4 to 8 years old, and 5 adults. Experimental results were compared with analytical predictions made using published airway resistance models. For the adult replicas, the model proposed by van Ertbruggen et al. (2005. J. Appl. Physiol. 98, 970-980) most accurately predicted central conducting airway resistance for inspiratory flow rates ranging from 15 to 90 L/min. Models proposed by Pedley et al. (1970. J. Respir. Physiol. 9, 371-386) and by Katz et al. (2011. J. Biomech. 44, 1137-1143) also provided reasonable estimates, but with a tendency to over predict measured pressure loss for both models. For child replicas, the Pedley and Katz models both provided good estimation of measured pressure loss at flow rates representative of resting tidal breathing, but under predicted measured values at high inspiratory flow rate (60 L/min). The van Ertbruggen model, developed based on flow simulations performed in an adult airway model, tended to under predict measured pressure loss through the child replicas across the range of flow rates studied (2 to 60 L/min). These results are intended to provide guidance for selection of analytical pressure loss models for use in predicting airway resistance and ventilation distribution in adults and children.

    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

    Agents targeting the vascular endothelial growth factor (VEGF) pathway have been studied in adults with cancer for nearly two decades. It is important to assess the lessons learned from this adult experience and to see how these lessons can help inform pediatric development of agents in this class. The benefit achieved from the use of VEGF pathway targeted agents for adult cancers has primarily been to delay for several months disease progression and less commonly time to death for conditions in which cure is not a reasonable expectation. VEGF pathway targeted agents have shown no efficacy when applied in the adjuvant setting. For adults with advanced cancer, prolongation of survival by 2-3 months is considered an important achievement in some settings. However, the primary goal of pediatric oncology clinical research is to identify treatments that allow children to be cured of their cancer and to grow to adulthood without treatment-induced limitations that lower their quality of survival. An important question for the pediatric oncology research community, pharmaceutical companies, and regulatory agencies to address in planning for future clinical trials is whether existing data support a role for VEGF pathway targeted agents in contributing to a therapeutic pathway to cure for children with cancer.

    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. The seroprevalence of anti-CagA antibody was increased with age, up to 30 years and then decreased. It

    The development of language hemispheric specialization is not well understood in young children, especially regarding expressive language functions. In this study, we investigated age-related changes in expressive language lateralization patterns in a population of children (3-6 and 7-10 years old), adolescents (11-16 years old), and young adults (19-30 years old). During functional near-infrared spectroscopy recordings, all participants performed a verbal fluency task, which consisted in naming as many words as possible belonging to a given semantic category. Hemoglobin concentration changes were measured in bilateral frontal and temporal cortical areas. During the language task, results showed a strong left hemisphere response along with weaker right hemisphere activation in all groups. Age-related increases in hemodynamic responses were found bilaterally, with younger children showing smaller hemodynamic responses than adolescents and adults in both hemispheres. Overall, these findings confirm that a left hemisphere specialization is already established in young children and persists through adulthood. Early left hemisphere specialization for expressive language suggests that language development hinges on structural and functional properties of the human brain with little reorganization occurring with development.

    1992-12-01

    This study has empirically assessed whether artistic orientation and avoidance are good predictors of chronic career indecision for college-attending adult children and grandchildren of alcoholics. The sample consisted of 143 freshman and sophomore introductory psychology students attending a county college in the northeast. Osipow's Career Decision Scale total scores of artistically oriented children and grandchildren of alcoholics were not significantly higher than scores of those who were not artistic. As predicted, the Career Decision Scale total scores of avoidant subjects were significantly higher than those of nonavoidant subjects. As expected in both instances, no differences were found between artistic subjects and nonartistic subjects or between the avoidant and nonavoidant subjects. The findings suggest (1) that the artistic career-undecided children of alcoholics observed by Schumrum and Hartman in 1988 were, in fact, members of a broader avoidant group and (2) that the relationship between career indecision and avoidant personality style does vary according to family status of whether subjects are adult children and grandchildren of alcoholics.

    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 Abstract Background We tested the properties of the 18 Household Food Security Survey (HFSS items, and the validity of the resulting food security classifications, in an English-speaking middle-income country. Methods Survey of primary school children in Trinidad and Tobago. Parents completed the HFSS. Responses were analysed for the 10 adult-referenced items and the eight child-referenced items. Item response theory models were fitted. Item calibrations and subject scores from a one-parameter logistic (1PL model were compared with those from either two-parameter logistic model (2PL or a model for differential item functioning (DIF by ethnicity. Results There were 5219 eligible with 3858 (74% completing at least one food security item. Adult item calibrations (standard error in the 1PL model ranged from -4.082 (0.019 for the 'worried food would run out' item to 3.023 (0.042 for 'adults often do not eat for a whole day'. Child item calibrations ranged from -3.715 (0.025 for 'relied on a few kinds of low cost food' to 3.088 (0.039 for 'child didn't eat for a whole day'. Fitting either a 2PL model, which allowed discrimination parameters to vary between items, or a differential item functioning model, which allowed item calibrations to vary between ethnic groups, had little influence on interpretation. The classification based on the adult-referenced items showed that there were 19% of respondents who were food insecure without hunger, 10% food insecure with moderate hunger and 6% food insecure with severe hunger. The classification based on the child-referenced items showed that there were 23% of children who were food insecure without hunger and 9% food insecure with hunger. In both children and adults food insecurity showed a strong, graded association with lower monthly household income (P Conclusion These results support the use of 18 HFSS items to classify food security status of adults or children in an English-speaking country where food

    The importance of body composition measurements to elucidate the dynamics of related diseases in pediatrics is gaining recognition. The methods used should not expose subjects to high doses of radiation and require substantial cooperation. The Lipometer is a new optical device that enables the non-invasive, quick and safe determination of the thickness of subcutaneous adipose tissue (SAT) layers (in mm) at any site of the human body. The topographic specification of 15 evenly distributed body sites, which makes it possible to precisely measure subcutaneous body fat distribution, is called subcutaneous adipose tissue topography (SAT-Top). SAT-Top was determined in more than 1000 children and young adults between the ages of 7 and 21. In this paper we describe the SAT-Top development of these subjects through different age groups and the differences between male and female SAT-Top development in each age group. SAT layer profiles (medians of the 15 body sites) for boys and girls in age group 1 (7-9 yrs) show a very similar pattern for both sexes, followed by slightly decreasing SAT layer thicknesses in boys and increasing values in girls in the subsequent age groups. Between age group 3 (11-13 yrs) and age group 7 (19-21 yrs) male and female SAT-Top is significantly different. The discriminating power between male and female SAT-Top was investigated by stepwise discriminant analysis, which provided no significant results for age group 1 (7-9 yrs), about 73% correct classification for age group 2 (9-11 yrs) and 3 (11-13 yrs), 83% for age group 4 (13-15 yrs), and about 91-93% for the following age groups (15-21 yrs). It is known that SAT development is the same in both sexes until puberty, when girls gain relatively more fat mass than boys to reach a higher body-fat percentage as adults. This paper presents a precise description of SAT development in boys and girls from childhood to adolescence, which provides a basis for further investigations.

    This study was conducted to determine if significant differences exist between women in marital therapy who had been sexually abused as children and women in marital therapy who had not been sexually abused as children on the parameters of marital satisfaction and divorce potential. The null hypothesis was tested. No differences were found between the two groups. Both groups of women and their husbands experienced moderate marital dissatisfaction. Divorce potential for both groups and their husbands was low. The sexually abused women had significantly higher psychoticism scores on the SCL-90R than the nonabused women, generally representing moderately withdrawn, isolated lifestyle patterns.

    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.

    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.

    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.

    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.

    The objective of this research was to delineate age-based differences in specific thoracic injury diagnoses for seat belt restrained rear seat occupants and describe the associated injury causation in order to provide insight into how the load of the seat belt is transferred to occupants of various sizes. Using data from the Crash Investigation Research and Engineering Network (CIREN), 20 cases of rear seated, lap and shoulder belt restrained occupants with AIS2+ thoracic injuries in frontal crashes were reviewed. Seven were children and adolescents age 8-15 years, 5 were 16-24 years, 3 were 25-54 years, and 5 were 55+ years. Six of the seven 8-15 year olds sustained injuries to the lung in the form of pulmonary contusion or pneumothorax. Only three of the seven sustained a skeletal (sternum or rib) fracture; only one of these three involved multiple ribs bilaterally. In contrast, four of the five 16-24 year olds sustained at least one rib fracture - often multiple and bilateral. The adult cohort (25+ years) was involved in predominantly more minor crashes; however they all sustained complex rib fractures - seven of the eight involved multiple ribs, four of the eight were also bilateral. Belt compression - either from the shoulder belt or the lap belt - was identified as the primary cause of the thoracic injuries. Often, there was clear evidence of the location of belt loading from AIS 1 chest contusions or abrasions. These findings have implications for age-based thoracic injury criteria suggesting that that different metrics may be needed for different age groups.

    Research on caregiving children tends to be limited to children's caregiving experiences of parents with a specific disease or disability. This has led to a common perception that children's caregiving is a single, uniform and often long-term experience.

    2013-06-01

    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.

    Surveillance of incident influenza-like illness (ILI) was implemented in two children and adult medical emergency departments during the influenza A (H1/N1) pandemic to assess correlations in the daily number of ILI-related emergency room visits (ERV) between these departments. A total of 7165 ILIs in children and 610 ILIs in adults were observed. We noticed a high linear correlation between the number of ERV involving ILI on day D in the pediatric department and the number of ERV because of ILI 2 days later in adults (R = 0·82, P ILI-related ERV might be anticipated based on the rate of pediatric ERV.

    Purpose Peripheral neuropathy is an important, yet poorly studied, side effect of pediatric cancer treatment. There are many measures of patient-reported peripheral neuropathy in adults but very few in children. We aimed to systematically review and summarize reliable and valid patient-reported peripheral neuropathy scales used in pediatrics. Methods Four major electronic databases (Medline, Embase, EBSCO Host in Cumulative Index to Nursing and Allied Health Literature, and PsycINFO) were reviewed for studies that measured peripheral neuropathy in pediatric patients. Studies eligible for inclusion were those that described use of any patient-reported scale of peripheral neuropathy among children, adolescents, and young adults with any underlying diagnosis (not limited to cancer). Results From a total of 765 articles retrieved, 5 met eligibility criteria and were included. One was a neuropathy symptom score used in patients with diabetes, and the remaining four were in oncology patients and all were based on the total neuropathy score. All involved objective assessments conducted by trained professionals; none relied purely on patient report. Conclusions There are no validated instruments that consist solely of a patient-reported outcome measure of neuropathy in pediatrics and adolescents. Because the clinical evaluation of neuropathy requires specialized training, it is not generalizable in large studies conducted in many diverse institutions. Future studies should validate adult patient-reported neuropathy scales in pediatric and adolescent populations, or develop novel instruments designed for this population. PMID:27037813

    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.

    Family members in the United States--especially mothers--are frequently caregivers, and provide housing for their adult relatives and children with mental illness. They often do so with little support from the mental health system. The purpose of this analysis was to explore mothers' experiences related to housing options available to their adult children with a mental illness and a history of violence (MIHV) toward the mothers. The results of this study reveal a complex mixing of desires, feelings, internal factors, and external forces experienced by mothers of adult children with MIHV when considering whether or not these children can live in their homes. The findings from this study illuminate needs for greater familial involvement in mental health treatment decisions, respite for caregiving families, and housing as a crucial element of a comprehensive mental health treatment plan.

    The illusion of control can be defined as the erroneous belief that one's actions cause a specific outcome, whereas sense of agency refers to the subjective feeling of authorship over one's actions. In the present study we investigated the development of illusory control and sense of agency. A novel card-guessing game was developed in which 7- to-12-year old children (Study 1) and adults (Study 2) were required to select a card, and we manipulated the congruence of the outcome with their initial choice (i.e., congruent or incongruent) and the valence of the outcome that was presented (i.e., positive or negative). We found that illusory control and the self-attribution bias (i.e., the bias to attribute positive outcomes to oneself) in the card guessing game decreased, as children get older. In contrast, for both children and adults sense of agency in the task was similarly affected by outcome congruency, suggesting that the ability to relate predicted to observed action outcomes reflects a basic mechanism that helps people to sustain a sense of agency. Thus, while the illusion of control decreases as we get older, the experience of agency as a function of outcome congruency seems to be more stable across development.

    Full Text Available The development of upright postural control has often been investigated using time series of center of foot pressure (COP, which is proportional to the ankle joint torque (i.e., the motor output of a single joint. However, the center of body mass acceleration (COMacc, which can reflect joint motions throughout the body as well as multi-joint coordination, is useful for the assessment of the postural control strategy at the whole-body level. The purpose of the present study was to investigate children's postural control during quiet standing by using the COMacc. Ten healthy children and 15 healthy young adults were instructed to stand upright quietly on a force platform with their eyes open or closed. The COMacc as well as the COP in the anterior-posterior direction was obtained from ground reaction force measurement. We found that both the COMacc and COP could clearly distinguish the difference between age groups and visual conditions. We also found that the sway frequency of COMacc in children was higher than that in adults, for which differences in biomechanical and/or neural factors between age groups may be responsible. Our results imply that the COMacc can be an alternative force platform measure for assessing developmental changes in upright postural control.
