    This article summarizes a life-span neurodevelopmental MRI database. The study of neurostructural development or neurofunctional development has been hampered by the lack of age-appropriate MRI reference volumes. This causes misspecification of segmented data, irregular registrations, and the absence of appropriate stereotaxic volumes. We have created the "Neurodevelopmental MRI Database" that provides age-specific reference data from 2 weeks through 89 years of age. The data are presented in fine-grained ages (e.g., 3 months intervals through 1 year; 6 months intervals through 19.5 years; 5 year intervals from 20 through 89 years). The base component of the database at each age is an age-specific average MRI template. The average MRI templates are accompanied by segmented partial volume estimates for segmenting priors, and a common stereotaxic atlas for infant, pediatric, and adult participants. The database is available online (http://jerlab.psych.sc.edu/NeurodevelopmentalMRIDatabase/).

    We introduce three strategies for the analysis of financial time series based on time averaged observables. These comprise the time averaged mean squared displacement (MSD) as well as the ageing and delay time methods for varying fractions of the financial time series. We explore these concepts via statistical analysis of historic time series for several Dow Jones Industrial indices for the period from the 1960s to 2015. Remarkably, we discover a simple universal law for the delay time averaged MSD. The observed features of the financial time series dynamics agree well with our analytical results for the time averaged measurables for geometric Brownian motion, underlying the famed Black-Scholes-Merton model. The concepts we promote here are shown to be useful for financial data analysis and enable one to unveil new universal features of stock market dynamics.

    Starting from an invariant total dimension for an exceptional Lie symmetry groups hierarchy, we drive all the essential characteristic and coupling constants of the fundamental interactions of physics. It is shown in a most simplistic fashion that all physical fields are various transfinite scaling transformation and topological deformation of each other. An extended standard model on the other hand turned out to be a compact sub group H of a version of E7 exceptional Lie group E7(−5) with dimH =69. Thus particle physics, electromagnetism as well as gravity and the bulk are all representable via modular spaces akin to the famous compactified version of F. Klein’s modular curve.

    The MFA approach for simulations with dynamical fermions in lattice gauge theories allows in principle to explore the parameters space of the theory (e.g. the \\beta, m plane for the study of chiral condensate in QED) without the need of computing the fermionic determinant at each point. We exploit this possibility for extracting both the renormalization group trajectories ("constant physics lines") and the scaling function, and we test it in the Schwinger Model. We discuss the applicability of this method to realistic theories.

  7. Average use of Alcohol and Binge Drinking in Pregnancy: Neuropsychological Effects at Age 5

    Objectives The objective of this PhD. was to examine the relation between low weekly average maternal alcohol consumption and ‘Binge drinking' (defined as intake of 5 or more drinks per occasion) during pregnancy and information processing time (IPT) in children aged five years. Since a method...... to investigate IPT in very young children does not exist, it was decided to develop a method to test this based on Sternberg's paradigm. Method development Sternberg's original method of testing IPT used nine digits in a computer based program, where a subject had to decide whether a shown digit was found...... that provided detailed information on maternal alcohol drinking patterns before and during pregnancy and other lifestyle factors. These women were categorized in groups of prenatally average alcohol intake and binge drinking, timing and number of episodes. At the age of five years the children of these women...

    Full Text Available INTRODUCTION: Age Related Hearing Loss (ARHL is defined as loss of hearing in elderly persons not influe nced by the extraneous factors like noise trauma etc or intrinsic like CVS related diseases or endocrinal disorders like Diabetes. Also termed as Presbycusis it is defined as the loss of hearing due to age related changes taking place in the auditory syste m starting from the pinna to the cortical centers in the brain. It does not include any other factor contributing or initiating the pathological changes in the auditory system resulting in hearing loss. All these changes in the tissues are not pathological but truly age related. The threshold of hearing is defined as the pure tone average across the frequencies of 0.5 to 8 kHz. The severity of hearing loss is graded as profound hearing loss : more than 90dB , severe to severe loss : 71 - 90 dB or more ; Moderate to severe hearing loss : 56 - 70 , Moderate hearing loss : 41 - 55 dB HL ; Mild hearing loss : 26 - 40 dB HL. Present study is to evaluate hearing loss in persons aged above 65 years both of those attending the Hospital for loss of hearing and those screened in a sur vey. AIM: To evaluate the hearing thresholds in individuals aged above 65 years attending the Government General Hospital and among the people attending the hearing screening done in the city of Warangal. The study also includes the review of the literature on ARHL. MATERIALS AND METHODS: 185 individuals aged above 65 years are evaluated for hearing thresholds with the help of pure tone audiometry and speech audiometry. Among the 185 individuals 102 are patients attending the Department of ENT for the compla ints of loss of hearing. The remaining 83 individuals are from the survey conducted to screen for hearing loss in the city of Warangal for the population aged above 65 years. Demographic data about the 185 individuals is collected. Pure tone audiogram and speech audiometry is done in all the patients. CONCLUSIONS

    In the context of color perception on modern wide-gamut displays with narrowband spectral primaries, we performed a theoretical analysis on various aspects of physiological observers proposed by CIE TC 1-36 (CIEPO06). We allowed certain physiological factors to vary, which was not considered in the CIEPO06 framework. For example, we analyzed that the long-wave-sensitive (LWS) or medium-wave-sensitive (MWS) peak wavelength shift in the photopigment absorption spectra, a factor not modeled in CIEPO06, contributed more toward observer variability than some of the factors considered in the model. Further, we compared the color-matching functions derived from the CIEPO06 model and the CIE 10° standard colorimetric observer to the average observer data from three distinct subgroups of Stiles-Burch observers, formed on the basis of observer ages (22-23 years, 27-29 years, and 49-50 years). The errors in predicting the x(λ) and y(λ) color-matching functions of the intragroup average observers in the long-wave range and in the medium-wave range, respectively, were generally more in the case of the CIEPO06 model compared to the 10° standard colorimetric observer and manifested in both spectral and chromaticity space. In contrast, the short-wave-sensitive z₁₀(λ) function of the 10° standard colorimetric observer performed poorly compared to the CIEPO06 model for all three subgroups. Finally, a constrained nonlinear optimization on the CIEPO06 model outputs showed that a peak wavelength shift of photopigment density alone could not improve the model prediction errors at higher wavelengths. As an alternative, two optimized weighting functions for each of the LWS and MWS cone photopigment densities led to significant improvement in the prediction of intra-age-group average data for both the 22-23 year and 49-50 year age groups. We hypothesize that the assumption in the CIEPO06 model that the peak optical density of visual pigments does not vary with age is false and is

    We tested whether the perceived physical attractiveness of a group is greater than the average attractiveness of its members. In nine studies, we find evidence for the so-called group attractiveness effect (GA-effect), using female, male, and mixed-gender groups, indicating that group impressions of physical attractiveness are more positive than the average ratings of the group members. A meta-analysis on 33 comparisons reveals that the effect is medium to large (Cohen's d = 0.60) and moderated by group size. We explored two explanations for the GA-effect: (a) selective attention to attractive group members, and (b) the Gestalt principle of similarity. The results of our studies are in favor of the selective attention account: People selectively attend to the most attractive members of a group and their attractiveness has a greater influence on the evaluation of the group. © 2015 by the Society for Personality and Social Psychology, Inc.

  15. Patterns of Ageism in Different Age Groups

    2013-08-01

    Full Text Available This paper examines age-based stereotypes in accordance with the Stereotype Content Model in four different age groups: schoolchildren, adolescents, adults and the elderly. Participants were asked to rank graphic portraits of both genders of four age clusters in terms of warmth and competence. The hypothesis that age groups, besides a positive evaluation of their own age cluster, would rate old people in an increasingly negative way as they themselves get older, was not confirmed. On the contrary, young children seem to have the most extreme prejudice against older people. Interestingly, adults and elderly appear to evaluate their own age cluster rather negatively too. Other relations between age groups indicate that ageism does not only affect old people and that it can include positive stereotypes as well. It is also argued, that ageism may have a changing pattern throughout the lifespan.

  16. How many carboxyl groups does an average molecule of humic-like substances contain?

    Full Text Available The carboxyl groups of atmospheric humic-like substances (HULIS are of special interest because they influence the solubility in water, affect the water activity and surface tension of droplets in the air, and allow formation of chelates with biologically active elements. Experimentally determined abundances of the carboxyl group within HULIS by functional group analysis are consistent with our knowledge on the average molecular mass of HULIS if the number of dissociable carboxyl groups is assumed to be rather small. The best agreement between the average molecular mass derived from the existing abundance data and the average molecular mass published earlier occurs for assuming approximately one dissociable carboxyl group only. This implies that HULIS can not be regarded as polycarboxilic acid. The average molecular mass of HULIS derived from our electrochemical measurements with the assumption of one dissociable carboxyl group per molecule ranges from 248 to 305 Da. It was concluded that HULIS are a moderately strong/weak acid with a dissociation constant of about pK=3.4, which fits well into the interval represented by fulvic and humic acids. The mean number of dissociable carboxyl groups in HULIS molecules was refined to be between 1.1 and 1.4.

  18. Using Group Theory to Obtain Eigenvalues of Nonsymmetric Systems by Symmetry Averaging

    Full Text Available If the Hamiltonian in the time independent Schrödinger equation, HΨ = EΨ, is invariant under a group of symmetry transformations, the theory of group representations can help obtain the eigenvalues and eigenvectors of H. A finite group that is not a symmetry group of H is nevertheless a symmetry group of an operator Hsym projected from H by the process of symmetry averaging. In this case H = Hsym + HR where HR is the nonsymmetric remainder. Depending on the nature of the remainder, the solutions for the full operator may be obtained by perturbation theory. It is shown here that when H is represented as a matrix [H] over a basis symmetry adapted to the group, the reduced matrix elements of [Hsym] are simple averages of certain elements of [H], providing a substantial enhancement in computational efficiency. A series of examples are given for the smallest molecular graphs. The first is a two vertex graph corresponding to a heteronuclear diatomic molecule. The symmetrized component then corresponds to a homonuclear system. A three vertex system is symmetry averaged in the first case to Cs and in the second case to the nonabelian C3v. These examples illustrate key aspects of the symmetry-averaging process.

  19. Age-specific average head template for typically developing 6-month-old infants.

    Full Text Available Due to the rapid anatomical changes that occur within the brain structure in early human development and the significant differences between infant brains and the widely used standard adult templates, it becomes increasingly important to utilize appropriate age- and population-specific average templates when analyzing infant neuroimaging data. In this study we created a new and highly detailed age-specific unbiased average head template in a standard MNI152-like infant coordinate system for healthy, typically developing 6-month-old infants by performing linear normalization, diffeomorphic normalization and iterative averaging processing on 60 subjects' structural images. The resulting age-specific average templates in a standard MNI152-like infant coordinate system demonstrate sharper anatomical detail and clarity compared to existing infant average templates and successfully retains the average head size of the 6-month-old infant. An example usage of the average infant templates transforms magnetoencephalography (MEG estimated activity locations from MEG's subject-specific head coordinate space to the standard MNI152-like infant coordinate space. We also created a new atlas that reflects the true 6-month-old infant brain anatomy. Average templates and atlas are publicly available on our website (http://ilabs.washington.edu/6-m-templates-atlas.

    In this paper, a new car following model is presented by considering the average speed effect of preceding vehicles group in cyber-physical systems (CPS) environment. The effect of this new consideration upon the stability of traffic flow is examined through linear stability analysis. A modified Korteweg-de Vries (mKdV) equation was derived via nonlinear analysis to describe the propagating behavior of traffic density wave near the critical point. Good agreement between the simulation and the analytical results shows that average speed of preceding vehicles group leads to the stabilization of traffic systems, and thus can efficiently suppress the emergence of traffic jamming.

    Full Text Available The aim of this study is to identify the underlying factors that explain the average age of death in the City of Hamilton, Ontario, Canada, as identified in the Code Red Series of articles that were published in the city's local newspaper in 2010. Using a combination of data from the Canadian Census, the Government of Ontario and the Canadian Institute for Health Information, factor analysis was performed yielding three factors relating to poverty, working class, and health and aging. In a regression analysis these factors account for 42% of the total variability in the average ages of death observed at the census tract level of geography within the city.

Work purpose: studying of average diameter of erythrocytes at children of early age, patients with pneumonia and ARVI. Determination of average diameter of erythrocytes was carried out by a diffraction method on identical structure of chaotic objects at 36 children with pneumonia and at 41 children with a ARVI aged from 4 months till 3 years. The control group was made by 20 almost healthy children of the same age. During the sharp period of a disease the average diameter of erythrocytes was authentically increased both at pneumonia, and at a ARVI. Reliable difference of these indicators when comparing a toxic syndrome at pneumonia and a ARVI is revealed. Thus, at children of early age, patients with pneumonia and ARVI, in dynamics of a disease the natural changes of average diameter of erythrocytes having differential and diagnostic and predictive value are revealed.

    According to current guidelines, screening colonoscopy begins at 50 years for the average-risk population, although there are not enough data on the incidence of precancerous lesions of individuals in the preceding decades. To evaluate the prevalence of colorectal polyps including potentially premalignant lesions in asymptomatic, average-risk individuals aged 40-49 versus 50-59 years, we offered total colonoscopy screening to individuals without any lower gastrointestinal symptoms. The primary end point was the prevalence of colorectal adenoma in two age groups. Of a total of 737 studies, 333 participants were 40-49 years old and 407 participants were 50-59 years old. The overall prevalence of adenomas was 11.2 and 16.4% in the group of 40-49 and 50-59 year olds, respectively. Advanced adenoma was more common in 50-59 year olds (1.2 vs. 2.9%). Malignancy was not reported in these groups. Furthermore, 77.5 and 68.6% of adenomas were observed in the distal colon in the groups of 40-49 year olds and 50-59 year olds, whereas in the proximal colon, 22.2 and 57.1% of adenomas in the groups of 40-49 year olds and 50-59 year olds, respectively, were advanced adenomas. In our study, male sex showed an association with adenoma. However, importantly, there was no significant association between age and colorectal adenoma. Although the prevalence of colorectal adenoma was similar in the two age groups investigated, the rate of advanced adenoma was higher in the group of individuals who were 50-59 years old, suggesting that colorectal cancer screening could be recommended at an age younger than 50 years.

    Full Text Available BACKGROUND: Pityriasis versicolor (PV is a mild chronic infection of the skin caused by Malassezia yeasts. Although it is primarily seen in adults, children are often affected in the tropics . METHODS: Over a period of 2 years, children (up to the age of 14 years who were clinically and mycologically diagnosed as PV were included in the study. The clinical and epidemiological pattern in different age groups was noted. RESULTS: PV in this age group formed about 31% of the total cases of PV; 4.8% cases presented in infancy. The commonest site of involvement was the face in 39.9% of the cases. Most of the cases presented in summer months. CONCLUSIONS: PV is not an uncommon disease among children in the tropics. There is a sudden resurgence of cases in the hot monsoons and even infants are not spared.

    From midlife onwards, age stereotypes increasingly underlie social judgments and contribute to age-based discrimination. Whereas many studies compare differences between young and older adults in reports of age discrimination or sensitivity to age stereotypes, few consider age group differences among adults over 50. We form subgroups corresponding to social age group membership (early midlife, late midlife, young old, oldest old) and examine differences in reported experiences of everyday age discrimination and associations with self-perceptions of aging. Using cross-sectional and longitudinal data from the Health and Retirement Study (HRS: N = 15,071; M Age = 68, range 50-101), multivariate logistic regression was used to examine experiences of everyday discrimination attributed to age, and associations between age discrimination and self-perceptions of aging, in four age groups: early midlife, late midlife, young old, oldest old. People in the early midlife group (aged 50-59) reported more experiences of unfair treatment than the older age groups but were less likely to attribute their experiences to age discrimination. After controlling for covariates, individuals in all age groups who perceived their own aging positively were less likely to report experiences of age discrimination. The magnitude of this effect, however, was greatest in the early midlife group. Findings support proposals that midlife is a pivotal life period when individuals adjust to life events and social role transitions. Future longitudinal studies will provide further insight into whether positive self-perceptions of aging are especially important in this phase of the life course.

    Full Text Available We propose a new class of aggregation operator based on utility function and apply them to group decision-making problem. First of all, based on an optimal deviation model, a new operator called the interval generalized ordered weighted utility multiple averaging (IGOWUMA operator is proposed, it incorporates the risk attitude of decision-makers (DMs in the aggregation process. Some desirable properties of the IGOWUMA operator are studied afterward. Subsequently, under the hyperbolic absolute risk aversion (HARA utility function, another new operator named as interval generalized ordered weighted hyperbolic absolute risk aversion utility multiple averaging-HARA (IGOWUMA-HARA operator is also defined. Then, we discuss its families and find that it includes a wide range of aggregation operators. To determine the weights of the IGOWUMA-HARA operator, a preemptive nonlinear objective programming model is constructed, which can determine a uniform weighting vector to guarantee the uniform standard comparison between the alternatives and measure their fair competition under the condition of valid comparison between various alternatives. Moreover, a new approach for group decision-making is developed based on the IGOWUMA-HARA operator. Finally, a comparison analysis is carried out to illustrate the superiority of the proposed method and the result implies that our operator is superior to the existing operator.

  7. Group in social work with the aged

    Aspects of human behavior, including drives, needs, developmental tasks, aspirations, and wants, which are relevant for social work practice and for which the group is an indispensable instrumentality are discussed. Specific areas treated include common human needs, role and ego functioning, the roles of the social worker, and the differential impact of setting. Several ways in which groups can be used with the aged are outlined, including alleviation of isolation and aloneness and help in coping with the problem of loss of social identity, physical and mental loss, and the problem of lack of future. Groups can also be used to develop new social roles within the limits of present-day social instrumentalities, to develop a linkage of past, present, and future in relation to associational groups (e.g., family, peers) and to help create a new self-image of older adults which can be transmitted to society. It is pointed out that since most older persons who could benefit from group associations do not venture out on their own to join groups, social agencies have a responsibility to move out from their intramural confinement to the places where the elderly live.

    The purpose of this calculation is to develop additional Biosphere Dose Conversion Factors (BDCFs) for a reasonably maximally exposed individual (RMEI) for the periods 10,000 years and 1,000,000 years after the repository closure. In addition, Biosphere Dose Conversion Factors for the average member of a critical group are calculated for those additional radionuclides postulated to reach the environment during the period after 10,000 years and up to 1,000,000 years. After the permanent closure of the repository, the engineered systems within the repository will eventually lose their abilities to contain radionuclide inventory, and the radionuclides will migrate through the geosphere and eventually enter the local water table moving toward inhabited areas. The primary release scenario is a groundwater well used for drinking water supply and irrigation, and this calculation takes these postulated releases and follows them through various pathways until they result in a dose to either a member of critical group or a reasonably maximally exposed individual. The pathways considered in this calculation include inhalation, ingestion, and direct exposure.

    Full Text Available BACKGROUND: Specific learning disabilities (SpLD viz. dyslexia, dysgraphia and dyscalculia are an important cause of academic underachievement. Aims: To assess whether cognition abilities vary in children with SpLD having different grades of nonverbal intelligence. SETTING: Government recognized clinic in a medical college. DESIGN: Cross-sectional study. SUBJECTS AND METHODS: Ninety-five children with SpLD (aged 9-14 years were assessed. An academic achievement of two years below the actual grade placement on educational assessment with a Curriculum-Based test was considered diagnostic of SpLD. On basis of their nonverbal Intelligence Quotient (IQ scores obtained on the Wechsler Intelligence Scale for Children test, the study children were divided into three groups: (i average-nonverbal intelligence group (IQ 90-109, (ii bright normal-nonverbal intelligence group (IQ 110-119, and (iii superior-nonverbal intelligence group (IQ 120-129. A battery of 13 Cognition Function tests (CFTs devised by Jnana Prabodhini′s Institute of Psychology, Pune based on Guilford′s Structure of Intellect Model was administered individually on each child in the four areas of information viz. figural, symbolic, semantic and behavioral. STATISTICAL ANALYSIS USED: The mean CFTs scores obtained in the four areas of information were calculated for each of the three groups and compared using one-way analysis of variance test. A P value < 0.05 was to be considered statistically significant. RESULTS: There were no statistically significant differences between their mean CFTs scores in any of the four areas of information. CONCLUSIONS: Cognition abilities are similar in children with SpLD having average, bright-normal and superior nonverbal intelligence.

    We examined how recent biased face experience affects the influence of averageness on judgments of facial attractiveness among 8- and 9-year-old children attending a girls' school, a boys' school, and a mixed-sex school. We presented pairs of individual faces in which one face was transformed 50% toward its group average, whereas the other face was transformed 50% away from that average. Across blocks, the faces varied in age (adult, 9-year-old, or 5-year-old) and sex (male or female). We expected that averageness might influence attractiveness judgments more strongly for same-age faces and, for children attending single-sex schools, same-sex faces of that age because their prototype(s) should be best tuned to the faces they see most frequently. Averageness influenced children's judgments of attractiveness, but the strength of the influence was not modulated by the age of the face, nor did the effects of sex of face differ across schools. Recent biased experience might not have affected the results because of similarities between the average faces of different ages and sexes and/or because a minimum level of experience with a particular group of faces may be adequate for the formation of a veridical prototype and its influence on judgments of attractiveness. The results suggest that averageness affects children's judgments of the attractiveness of the faces they encounter in everyday life regardless of age or sex of face. Copyright © 2013 Elsevier Inc.

    We reexamine the functional renormalization-group theory of wetting transitions. As a starting point of the analysis we apply an exact equation describing renormalization group flow of the generating functional for irreducible vertex functions. We show how the standard nonlinear renormalization group theory of wetting transitions can be recovered by a very simple truncation of the exact flow equation. The derivation makes all the involved approximations transparent and demonstrates the applicability of the approach in any spatial dimension d≥2. Exploiting the nonuniqueness of the renormalization-group cutoff scheme, we find, however, that the capillary parameter ω is a scheme-dependent quantity below d=3. For d=3 the parameter ω is perfectly robust against scheme variation.

    Colorectal cancer (CRC) is one of the prime causes of mortality around the globe, with a significantly rising incidence in the Middle East region in recent decades. Since detection of CRC in the early stages is an important issue, and also since to date there are no comprehensive epidemiologic studies depicting the Middle East region with special attention to the average risk group, further investigation is of significant necessity in this regard. Our aim was to investigate the prevalence of preneoplastic and neoplastic lesions of the colon in an average risk population. A total of 1,208 eligible asymptomatic, average- risk adults older than 40 years of age, referred to Firuzgar Hospotal in the years 2008-2012, were enrolled. They underwent colonoscopy screening and all polypoid lesions were removed and examined by an expert gastrointestinal pathologist. The lesions were classified by size, location, numbers and pathologic findings. Size of lesions was measured objectively by endoscopists. The mean age of participants was 56.5±9.59 and 51.6% were male. The overall polyp detection rate was 199/1208 (16.5 %), 26 subjects having non-neoplastic polyps, including hyperplastic lesions, and 173/1208 (14.3%) having neoplastic polyps, of which 26 (2.15%) were advanced neoplasms .The prevalence of colorectal neoplasia was more common among the 50-59 age group. Advanced adenoma was more frequent among the 60-69 age group. The majority of adenomas were detected in the distal colon, but a quarter of advanced adenomas were found in the proximal colon; advance age and male gender was associated with the presence of adenoma. It seems that CRC screening among average-risk population might be recommended in countries such as Iran. However, sigmioidoscopy alone would miss many colorectal adenomas. Furthermore, the 50-59 age group could be considered as an appropriate target population for this purpose in Iran.

    Full Text Available INTRODUCTION : Adolescent pregnancy is a common problem encountered in developing countries like India due to early age of marriage. This was seen in women with lower socioeconomic status. Many studies have shown conflicting results . AIM OF THE STUDY : To study the maternal and fetal effects of ad olescent pregnancy. MATERIALS AND METHO DS : This is a hospital based retrospective study done in Yenepoya Medical C ollege over a period of 18 months. All patients with age between 10 - 19 years were included. EXCLUSION CRITERIA: Multiple gestation, patients w ith chronic diseases like, chronic hypertension and diabetes, congenital heart disease and chronic renal disease. RESULTS : Teenage pregnancies are associated with increased incidence of preterm birth, low birth weight babies, delivery by forceps of vacuum , caesarean section and low APGAR at birth . CONCLUSION : Teenage women are more likely to have anaemia, preterm birth, low birth weight babies, delivery by forceps or vacuum or by caesarean section. Good family support, preconceptional counselling, regular antenatal care may improve the perinatal outcome to some extent.

    The objective of the present study was to investigate how group composition affects behavior and weight gain of newly weaned dairy calves and how age within heterogeneous groups affects behavior and competition. Seventy-two calves were introduced into 6 groups of 12 calves, of which 3 groups were homogeneous and 3 groups were heterogeneous (including 6 young and 6 old calves). The 9.8 mx9.5 m large experimental pen had 4 separate lying areas as well as a feeding area. Behavior and subgrouping were recorded on d 1, 7, and 14 after grouping, and calves were weighed before and after the experimental period of 14 d. Analysis of the effect of group composition on behavior and weight gain included young calves in heterogeneous groups and calves in homogeneous groups within the same age range at grouping (30 to 42 d). Irrespective of group composition, time spent feeding and lying increased, whereas time spent active decreased from d 1 to 7. In homogeneous groups, calves were more explorative on d 1 after grouping. Finally, calves in homogeneous groups had a higher average daily weight gain than calves in heterogeneous groups. Analysis of the effect of age included young and old calves of heterogeneous groups. Young calves were less explorative than old calves. Young calves were more active than old calves on d 1 but less active on d 7. Time spent lying and lying alone increased over time. More displacements from the feed manger were performed by old calves than by young calves. An analysis including all calves in both homogeneous and heterogeneous groups showed that when lying, calves were evenly distributed on the 4 lying areas and formed subgroups of on average 3 calves. In conclusion, age heterogeneity leads to increased competition, which may have a negative influence on the young calves' performance.

    The average bond energies D(gm)(B-Z) for boron-containing molecules have been calculated by the Pauling geometric-mean equation. These calculated bond energies are compared with the average bond energies D(exp)(B-Z) obtained from experimental data. The higher values of D(exp)(B-Z) in comparison with D(gm)(B-Z) when Z is an element in the fifth, sixth, or seventh periodic group may be attributed to resonance stabilization or double-bond character.

    Full Text Available The magnitude of socioeconomic health inequalities differs across age groups. It is less clear whether socioeconomic health inequalities differ across age groups by other factors that are known to affect the relation between socioeconomic position and health, like the indicator of socioeconomic position, the health outcome, gender, and as to whether socioeconomic health inequalities are measured in absolute or in relative terms. The aim is to investigate whether absolute and relative socioeconomic health inequalities differ across age groups by indicator of socioeconomic position, health outcome and gender.The study sample was derived from the baseline measurement of the LifeLines Cohort Study and consisted of 95,432 participants. Socioeconomic position was measured as educational level and household income. Physical and mental health were measured with the RAND-36. Age concerned eleven 5-years age groups. Absolute inequalities were examined by comparing means. Relative inequalities were examined by comparing Gini-coefficients. Analyses were performed for both health outcomes by both educational level and household income. Analyses were performed for all age groups, and stratified by gender.Absolute and relative socioeconomic health inequalities differed across age groups by indicator of socioeconomic position, health outcome, and gender. Absolute inequalities were most pronounced for mental health by household income. They were larger in younger than older age groups. Relative inequalities were most pronounced for physical health by educational level. Gini-coefficients were largest in young age groups and smallest in older age groups.Absolute and relative socioeconomic health inequalities differed cross-sectionally across age groups by indicator of socioeconomic position, health outcome and gender. Researchers should critically consider the implications of choosing a specific age group, in addition to the indicator of socioeconomic position and

    Full Text Available Abstract Background DNA methylation plays a vital role in normal cellular function, with aberrant methylation signatures being implicated in a growing number of human pathologies and complex human traits. Methods based on the modification of genomic DNA with sodium bisulfite are considered the 'gold-standard' for DNA methylation profiling on genomic DNA; however, they require relatively large amounts of DNA and may be prohibitively expensive when used on the large sample sizes necessary to detect small effects. We propose that a high-throughput DNA pooling approach will facilitate the use of emerging methylomic profiling techniques in large samples. Results Compared with data generated from 89 individual samples, our analysis of 205 CpG sites spanning nine independent regions of the genome demonstrates that DNA pools can be used to provide an accurate and reliable quantitative estimate of average group DNA methylation. Comparison of data generated from the pooled DNA samples with results averaged across the individual samples comprising each pool revealed highly significant correlations for individual CpG sites across all nine regions, with an average overall correlation across all regions and pools of 0.95 (95% bootstrapped confidence intervals: 0.94 to 0.96. Conclusion In this study we demonstrate the validity of using pooled DNA samples to accurately assess group DNA methylation averages. Such an approach can be readily applied to the assessment of disease phenotypes reducing the time, cost and amount of DNA starting material required for large-scale epigenetic analyses.

  20. Aging underdamped scaled Brownian motion: Ensemble- and time-averaged particle displacements, nonergodicity, and the failure of the overdamping approximation

    We investigate both analytically and by computer simulations the ensemble- and time-averaged, nonergodic, and aging properties of massive particles diffusing in a medium with a time dependent diffusivity. We call this stochastic diffusion process the (aging) underdamped scaled Brownian motion (UDSBM). We demonstrate how the mean squared displacement (MSD) and the time-averaged MSD of UDSBM are affected by the inertial term in the Langevin equation, both at short, intermediate, and even long diffusion times. In particular, we quantify the ballistic regime for the MSD and the time-averaged MSD as well as the spread of individual time-averaged MSD trajectories. One of the main effects we observe is that, both for the MSD and the time-averaged MSD, for superdiffusive UDSBM the ballistic regime is much shorter than for ordinary Brownian motion. In contrast, for subdiffusive UDSBM, the ballistic region extends to much longer diffusion times. Therefore, particular care needs to be taken under what conditions the overdamped limit indeed provides a correct description, even in the long time limit. We also analyze to what extent ergodicity in the Boltzmann-Khinchin sense in this nonstationary system is broken, both for subdiffusive and superdiffusive UDSBM. Finally, the limiting case of ultraslow UDSBM is considered, with a mixed logarithmic and power-law dependence of the ensemble- and time-averaged MSDs of the particles. In the limit of strong aging, remarkably, the ordinary UDSBM and the ultraslow UDSBM behave similarly in the short time ballistic limit. The approaches developed here open ways for considering other stochastic processes under physically important conditions when a finite particle mass and aging in the system cannot be neglected.

    In the present paper, one remote sensing index-age group vegetation index (AGVI) was put forward, and its feasibility was verified. Taking 518 groups of pine forest age group data collected in 13 counties (cities) of Sanming, Jiangle, Shaxian, Nanping, Huaan, Yunxiao, Nanping, Anxi, Putian, Changting, Jianyang, Ningde and Fuqing, Fujian Province and HJ-1 CCD multi-spectral image at the same time-phase as the basis, the spectrum differences of blue, green, red, near infrared and NDVI of each age group were analyzed, showing the characteristics of young forest>middle-aged forest>over-mature forest>mature forest>near mature forest at near infrared band and mature forest>near mature forest>over-mature forest>young forest>middle-aged forest at NDVI, thus the age group vegetation index (AGVI) was constructed; the index could increase the absolute and relative spectrum differences among age groups. For the pine forest AGVI, cluster analysis was conducted with K-mean method, showing that the division accuracy of pine forest age group was 80.45%, and the accurate rate was 90.41%. Therefore, the effectiveness of age group vegetation index constructed was confirmed.

    Age is an important factor when considering phenotypic changes in health and disease. Currently, the use of age information in medicine is somewhat simplistic, with ages commonly being grouped into a small number of crude ranges reflecting the major stages of development and aging, such as childhood or adolescence. Here, we investigate the possibility of redefining age groups using the recently developed Age-Phenome Knowledge-base (APK) that holds over 35,000 literature-derived entries describing relationships between age and phenotype. Clustering of APK data suggests 13 new, partially overlapping, age groups. The diseases that define these groups suggest that the proposed divisions are biologically meaningful. We further show that the number of different age ranges that should be considered depends on the type of disease being evaluated. This finding was further strengthened by similar results obtained from clinical blood measurement data. The grouping of diseases that share a similar pattern of disease-related reports directly mirrors, in some cases, medical knowledge of disease-age relationships. In other cases, our results may be used to generate new and reasonable hypotheses regarding links between diseases.

    2015-01-01

    This paper uses individual-level data from the German Socio-Economic Panel to model trends in population health in terms of cognition, physical fitness, and mental health between 2006 and 2012. The focus is on the population aged 50-90. We use a repeated population-based cross-sectional design. As outcome measures, we use SF-12 measures of physical and mental health and the Symbol-Digit Test (SDT) that captures cognitive processing speed. In line with previous research we find a highly significant Flynn effect on cognition; i.e., SDT scores are higher among those who were tested more recently (at the same age). This result holds for men and women, all age groups, and across all levels of education. While we observe a secular improvement in terms of cognitive functioning, at the same time, average physical and mental health has declined. The decline in average physical health is shown to be stronger for men than for women and found to be strongest for low-educated, young-old men aged 50-64: the decline over the 6-year interval in average physical health is estimated to amount to about 0.37 SD, whereas average fluid cognition improved by about 0.29 SD. This pattern of results at the population-level (trends in average population health) stands in interesting contrast to the positive association of physical health and cognitive functioning at the individual-level. The findings underscore the multi-dimensionality of health and the aging process.

    The notions of the order of a symmetry group may be extended to that of an average, non-integer order. Building on this extension, it can be shown that the five classical exceptional Lie symmetry groups could be extended to a hierarchy, the total sum of which is four times {alpha}-bar{sub 0}=137+k{sub 0} of the electromagnetic field. Subsequently it can be shown that all known and conjectured physical fields may be derived by E-infinity transfinite scaling transformation. Consequently E{sub 8}E{sub 8} exceptional Lie symmetry groups manifold, the SL(2,7){sub c} holographic modular curve boundary {gamma}(7), Einstein-Kaluza gravity R{sup (n=4)} and R{sup (n=5)} as well as the electromagnetic field are all topological transformations of each other. It is largely a matter of mathematical taste to choose E{sub 8} or the electromagnetic field associated with {alpha}-bar{sub 0} as derived or as fundamental. However since E{sub 8} has been extensively studied by the founding father of group theory and has recently been mapped completely, it seems beneficial to discuss at least high energy physics starting from the largest of the exceptional groups.

We have identified a number of differences between the two age groups associated with both features individually-psychological sphere, and in the psycho-physiological features. Features of age-related psychological differences can be explained by the age characteristics of the representatives of each group; psycho-physiological features of age differences may reflect developed in the course of a long professional activity features. We have also developed adaptive strategies, consciously or unconsciously selected during the long-running monotonous activities and in small social groups (teams of drivers allow, on the one hand, higher quality performance of their professional duties, on the other — to avoid the harmful effects of stressful situations at work. It can be assumed that the composition of drivers age group 35– 45 years is the result of natural selection, when those who did not cope with this type of activity is simply dismissed or transferred to other kinds of professions

  12. Approximate Solution of the Point Reactor Kinetic Equations of Average One-Group of Delayed Neutrons for Step Reactivity Insertion

    2012-04-01

    Full Text Available The understanding of the time-dependent behaviour of the neutron population in a nuclear reactor in response to either a planned or unplanned change in the reactor conditions is of great importance to the safe and reliable operation of the reactor. In this study two analytical methods have been presented to solve the point kinetic equations of average one-group of delayed neutrons. These methods which are both approximate solution of the point reactor kinetic equations are compared with a numerical solution using the Euler’s first order method. To obtain accurate solution for the Euler method, a relatively small time step was chosen for the numerical solution. These methods are applied to different types of reactivity to check the validity of the analytical method by comparing the analytical results with the numerical results. From the results, it is observed that the analytical solution agrees well with the numerical solution.

    We obtain exact analytic expressions for a class of functions expressed as integrals over the Haar measure of the unitary group in d dimensions. Based on these general mathematical results, we investigate generic dynamical properties of complex open quantum systems, employing arguments from ensemble theory. We further generalize these results to arbitrary eigenvalue distributions, allowing a detailed comparison of typical regular and chaotic systems with the help of concepts from random matrix theory. To illustrate the physical relevance and the general applicability of our results we present a series of examples related to the fields of open quantum systems and nonequilibrium quantum thermodynamics. These include the effect of initial correlations, the average quantum dynamical maps, the generic dynamics of system-environment pure state entanglement and, finally, the equilibration of generic open and closed quantum systems.

    Full Text Available Objective: To evaluate the impact of asthma on patients in Brazil, by age group (12-17 years, 18-40 years, and ≥ 41 years. Methods: From a survey conducted in Latin America in 2011, we obtained data on 400 patients diagnosed with asthma and residing in one of four Brazilian state capitals (São Paulo, Rio de Janeiro, Curitiba, and Salvador. The data had been collected using a standardized questionnaire in face-to-face interviews. For the patients who were minors, the parents/guardians had completed the questionnaire. The questions addressed asthma control, number of hospitalizations, number of emergency room visits, and school/work absenteeism, as well as the impact of asthma on the quality of life, sleep, and leisure. We stratified the data by the selected age groups. Results: The proportions of patients who responded in the affirmative to the following questions were significantly higher in the 12- to 17-year age group than in the other two groups: "Have you had at least one episode of severe asthma that prevented you from playing/exercising in the last 12 months?" (p = 0.012; "Have you been absent from school/work in the last 12 months?" (p < 0.001; "Have you discontinued your asthma relief or control medication in the last 12 months?" (p = 0.008. In addition, 30.2% of the patients in the 12- to 17-year age group reported that normal physical exertion was very limiting (p = 0.010 vs. the other groups, whereas 14% of the patients in the ≥ 41-year age group described social activities as very limiting (p = 0.011 vs. the other groups. Conclusions: In this sample, asthma had a greater impact on the patients between 12 and 17 years of age, which might be attributable to poor treatment compliance.

In this sample, asthma had a greater impact on the patients between 12 and 17 years of age, which might be attributable to poor treatment compliance.

    The present study examines age differences in the memory benefits from group-referncing. While prior work establishes that the memory performance of younger and older adults similarly benefits from relating information to the self, this study assessed whether those benefits extend to referencing a meaningful group membership. Young and older adult participants encoded trait words by judging whether each word describes themselves, describes their group membership (selected for each age group), or is familiar. After a retention interval, participants completed a surprise recognition memory test. The results indicate that group-referencing increased recognition memory performance compared to the familiarity judgements for both young and older groups. However, the group-reference benefit is limited, emerging as smaller than the benefit from self-referencing. These results challenge previous findings of equivalent benefits for group-referencing and self-referencing, suggesting that such effects may not prevail under all conditions, including for older adults. The findings also highlight the need to examine the mechanisms of group-referencing that can lead to variability in the group-reference effect.

    Full Text Available The average annual decreasing rate of the total solar irradiance (TSI is increasing from the 22-nd to the 23-rd and 24-th cycles, because the Sun since the 1990 is in the phase decline of quasi-bicentennial variation. The portion of the solar energy absorbed by the Earth is decreasing. Decrease in the portion of TSI absorbed by the Earth since 1990 remains uncompensated by the Earth's radiation into space at the previous high level over a time interval determined by the thermal inertia of the Ocean. A long-term negative deviation of the Earth’s average annual energy balance from the equilibrium state is dictating corresponding variations in it’s the energy state. As a result, the Earth will have a negative average annual energy balance also in the future. This will lead to the beginning of the decreasing in the Earth's temperature and of the epoch of the Little Ice Age after the maximum phase of the 24-th solar cycle approximately since the end of 2014. The influence of the consecutive chain of the secondary feedback effects (the increase in the Bond albedo and the decrease in the concentration of greenhouse gases in the atmosphere due to cooling will lead to an additional reduction of the absorbed solar energy and reduce the greenhouse effect. The start of the TSI’s Grand Minimum is anticipated in the solar cycle 27±1 in 2043±11 and the beginning of the phase of deep cooling of the 19th Little Ice Age for the past 7,500 years around 2060±11.

    Purpose: To prospectively assess the performance of teleradiology-based CT colonography to screen a population group of an island, at average risk for colorectal cancer. Materials and methods: A cohort of 514 patients living in Madeira, Portugal, was enrolled in the study. Institutional review board approval was obtained and all patients signed an informed consent. All patients underwent both CT colonography and optical colonoscopy. CT colonography was interpreted by an experienced radiologist at a remote centre using tele-radiology. Per-patient sensitivity, specificity, positive (PPV) and negative (NPV) predictive values with 95% confidence intervals (95%CI) were calculated for colorectal adenomas and advanced neoplasia ≥6 mm. Results: 510 patients were included in the study. CT colonography obtained a per-patient sensitivity, specificity, PPV and, NPV for adenomas ≥6 mm of 98.11% (88.6–99.9% 95% CI), 90.97% (87.8–93.4% 95% CI), 56.52% (45.8–66.7% 95% CI), 99.75% (98.4–99.9% 95% CI). For advanced neoplasia ≥6 mm per-patient sensitivity, specificity, PPV and, NPV were 100% (86.7–100% 95% CI), 87.07% (83.6–89.9% 95% CI), 34.78% (25.3–45.5% 95% CI) and 100% (98.8–100% 95% CI), respectively. Conclusion: In this prospective trial, teleradiology-based CT colonography was accurate to screen a patient cohort of a remote island, at average risk for colorectal cancer.

    Age-group differences were examined in the delayed oculomotor response task, which requires that observers delay the execution of a saccade (eye movement) toward an abrupt-onset visual cue. This task differs from antisaccade and attentional capture in that inhibition causes saccades to be postponed, not redirected. Older adults executed more premature saccades than young adults, but there were no age-group differences in latency or accuracy of saccades executed at the proper time. The results suggest that older adults are less capable of inhibiting a prepotent saccadic response, but that other aspects of visual working memory related to the task are preserved.

    Full Text Available BACKGROUND AND AIMS The “fallopian tubes” (oviducts or uterine tubes are long paired flexuous reproductive organ which transports ova, spermatozoa, zygotes, the pre-implantation morulae and blastocyst. It has major role during reproductive period, but it remains as if vestigial organ before puberty and after menopause. Due to increasing rate of tubal block and infertility, oviducts and their structures gaining importance and have become a subject of research in present days particularly epithelium. The aim of the study is to ascertain any histological difference of tubal epithelium in different age groups and the research work could be utilized for investigation and management of infertility. MATERIALS AND METHODS Seven samples of each group i.e., prereproductive, reproductive & postmenopausal were collected from fresh unembalmed human cadavers received in the department of Anatomy, FAA Medical College, Barpeta, Assam. The slides were prepared using the standard laboratory procedure. Under low and high power objectives the type of cells were observed and epithelial height was measured in the different segments. Stress was given for any significant difference of epithelial height between the different age groups. RESULTS Study revealed that among the groups within the same segment, epithelial height was recorded highest (33.57µm in reproductive group as against the lowest (22.91µm in post-menopausal group. Epithelial structures of the prereproductive and reproductive groups were significantly differed (p<0.01 from the postmenopausal group. CONCLUSIONS From the findings of the present study it can be concluded that: 1. In all the groups fallopian tubal epithelium is of simple columnar type and contains three types of cells. Cells are ciliated, secretory & peg (intercalary cells. 2. In all the groups same type of increasing trend of epithelial height from intramural segment to ampullary segment was recorded. 3.

    Full Text Available Background: The microscopic structure of spleen is variable depending on the developmental stage of the organ, and the age and immune status of the individual. The aim of the investigation was to study the microscopic structure of human spleen in different age groups, starting from a six month old foetus up to the eighth decade of life. Methods: Seventy formalin fixed human spleens obtained postmortem, were included in the study. They were classified into different age groups, in both sexes, for a detailed study of the microscopic details. Results: The white pulp of spleen showed peri-arteriolar lymphatic sheath (PALS and lymphatic follicles. The corona or mantle zone and the germinal centre were discernible in many of the Malpighian bodies. The marginal zone separating the red pulp from the white pulp also could be clearly demarcated. The marginal sinus and peri-follicular zone could be seen in some sections only. The capsule thickness, trabecular network, cellularity of white pulp and red pulp, the connective tissue framework seen in the red pulp etc., showed variations in the different age groups. Conclusion: The microscopic structure of spleen varies in different age groups, with the PALS and the white pulp showing scanty cellularity in the six month foetus, and almost uniform cellularity in all areas of spleen at full term. Thereafter the follicles showed increase in its cellularity up to the third decade, and then seemed becoming progressively atrophic. Further studies are required on age related changes in the cellular architecture of this organ correlating with its functions. [Int J Res Med Sci 2015; 3(7.000: 1701-1706

    2014-03-01

    Full Text Available Background: Lung diseases are assuming greater relevance and importance today. Chronic bronchitis is a self-nosology, which may precede the development of COPD, the importance of which can hardly be overestimated. The main problem in this disease is caused by late diagnosis and treatment due to the delay by patients in seeking medical help. The aim of the work was to study the distribution and exposure to tobacco smoke, especially chronic bronchitis, depending on various factors, including age. Methods: We examined 1779 persons, including 855 men and 924 women. The mean age of the population was 35.83±8.3 years. We conducted surveys and spirometry. The outcome was assessed after a bronchodilation test was performed with salbutamol 400 mcg. We performed all statistical analysis using software package Statistica 10. Results: We identified chronic bronchitis in 9.2% of the cases in the group of younger individuals and in 14.9% of the cases in the group of older individuals, during the active detection of chronic bronchitis using questionnaires. The prevalence of cigarette smoking was slightly higher among the younger (39.5% than the older persons (33.6%; the frequency of smoking in a group of chronic bronchitis was reliably higher. Also, in this group, the performance spirometry reliably decreased. Conclusions: Outpatient survey is an effective method of identifying chronic bronchitis. Smoking is a major risk factor in the group of young respondents and the prevalence of smoking is inversely related to the education level of the respondents, regardless of age. As the decline in the Forced Expiratory Volume (FEV1 and FEV1/FVC is the main criterion diagnosis of COPD, it revealed significant declines in the FEV1 of the younger smoking individuals, which may help to predict the development of COPD in the older age group.

  3. Episodic memory, concentrated attention and processing speed in aging: A comparative study of Brazilian age groups

    Rochele Paz Fonseca

    Full Text Available Abstract Neuropsychological studies on the processing of some specific cognitive functions throughout aging are essential for the understanding of human cognitive development from ages 19 to 89. Objectives: This study aimed to verify the occurrence of differences in the processing of episodic memory, concentrated attention and speed of attentional processing among four age groups of adults. Methods: A total of 136 neurologically healthy adults, aged 19-89, with 9 or more years of schooling, took part in the study. Participants were divided according to four age groups: young, middle-aged, elderly and oldest old adults. Subtests of the Brief Neuropsychological Evaluation Instrument (NEUPSILIN were applied for the cognitive assessment. Mean score of corrected answers and of response times were compared between groups by means of a one-way ANOVA test with post-hoc Scheffe procedures and ANCOVA including the co-variables of years of schooling and socio-economical scores. Results: In general, differences in performance were observed from 60 years old on. Only the episodic memory task of delayed recall reflected differences from the age of around 40 onwards and processing speed from around the age of 70 onwards. Thus, differences were found between the age groups regarding their cognitive performance, particularly between young adults and elderly adults, and young adults and oldest old adults. Conclusions: Our research indicates that the middle-aged group should be better analyzed and that comparative cross-sectional studies including only extreme groups such as young and elderly adults are not sufficient.

    Purpose: Polymethylmethacrylate (PMMA) slab is one of the mostly used phantoms for studying breast dosimetry in mammography. The purpose of this study was to evaluate the equivalence between exposure factors acquired from PMMA slabs and patient cases of different age groups of Taiwanese women in mammography. Methods: This study included 3910 craniocaudal screen/film mammograms on Taiwanese women acquired on one mammographic unit. The tube loading, compressed breast thickness (CBT), compression force, tube voltage, and target/filter combination for each mammogram were collected for all patients. The glandularity and the equivalent thickness of PMMA were determined for each breast using the exposure factors of the breast in combination with experimental measurements from breast-tissue-equivalent attenuation slabs. Equivalent thicknesses of PMMA to the breasts of Taiwanese women were then estimated. Results: The average {+-} standard deviation CBT and breast glandularity in this study were 4.2 {+-} 1.0 cm and 54% {+-} 23%, respectively. The average equivalent PMMA thickness was 4.0 {+-} 0.7 cm. PMMA slabs producing equivalent exposure factors as in the breasts of Taiwanese women were determined for the age groups 30-49 yr and 50-69 yr. For the 4-cm PMMA slab, the CBT and glandularity values of the equivalent breast were 4.1 cm and 65%, respectively, for the age group 30-49 yr and 4.4 cm and 44%, respectively, for the age group 50-69 yr. Conclusions: The average thickness of PMMA slabs producing the same exposure factors as observed in a large group of Taiwanese women is less than that reported for American women. The results from this study can provide useful information for determining a suitable thickness of PMMA for mammographic dose survey in Taiwan. The equivalence of PMMA slabs and the breasts of Taiwanese women is provided to allow average glandular dose assessment in clinical practice.

    The aim of the present study was to examine the reliability of tethered swimming in the evaluation of age group swimmers. The sample was composed of 8 male national level swimmers with at least 4 years of experience in competitive swimming. Each swimmer performed two 30 second maximal intensity tethered swimming tests, on separate days. Individual force-time curves were registered to assess maximum force, mean force and the mean impulse of force. Both consistency and reliability were very strong, with Cronbach’s Alpha values ranging from 0.970 to 0.995. All the applied metrics presented a very high agreement between tests, with the mean impulse of force presenting the highest. These results indicate that tethered swimming can be used to evaluate age group swimmers. Furthermore, better comprehension of the swimmers ability to effectively exert force in the water can be obtained using the impulse of force. PMID:25114742

    2011-07-01

    Protection of the transcriptional "stemness" network is important to maintain a healthy hematopoietic stem cells (HSCs) compartment during the lifetime of the organism. Recent evidence shows that fundamental changes in the epigenetic status of HSCs might be one of the driving forces behind many age-related HSC changes and might pave the way for HSC malignant transformation and subsequent leukemia development, the incidence of which increases exponentially with age. Polycomb group (PcG) proteins are key epigenetic regulators of HSC cellular fate decisions and are often found to be misregulated in human hematopoietic malignancies. In this review, we speculate that PcG proteins balance HSC aging against the risk of developing cancer, since a disturbance in PcG genes and proteins affects several important cellular processes such as cell fate decisions, senescence, apoptosis, and DNA damage repair.

    The present study examines how the overall cognitive achievements in science of the younger children in a class where the students work in small multi-age groups are influenced by the number of older children in the groups. The context of the study was early-years education. The study has two parts: The first part involved classes attended by pre-primary children aged 4-6. The second part included one primary class attended by students aged 6-8 in addition to the pre-primary classes. Students were involved in inquiry-based science activities. Two sources of data were used: Lesson recordings and children's assessments. The data from both sources were separately analyzed and the findings plotted. The resulting graphs indicate a linear relationship between the overall performance of the younger children in a class and the number of older ones participating in the groups in each class. It seems that the age composition of the groups can significantly affect the overall cognitive achievements of the younger children and preferentially determines the time within which this factor reaches its maximum value. The findings can be utilized in deciding the age composition of small groups in a class with the aim of facilitating the younger children's learning in science.

    Full Text Available BACKGROUND As per data from WHO, 21.6 million unsafe abortions occurred globally in 2008, out of which 47,000 women died from abortionrelated complications, contributing to 13% of global maternal mortality. (1 Emergency contraceptive can be used after intercourse to prevent pregnancy in case of unprotected intercourse, contraceptive failure or sexual assault. A considerable proportion of these abortions can be prevented by the timely use of emergency contraception. OBJECTIVES To study the knowledge of emergency contraceptives among women of reproductive age group. METHODS This is a government hospital-based prospective study done for a period of 3 months. The study included 500 women of reproductive age group (16 years to 40 years attending OPD of Obstetrics and Gynaecology Department of IGMC and RI, Pondicherry. A predesigned questionnaire is provided to women asking about awareness regarding emergency contraceptives. RESULTS Majority of them were between 20 and 30 years of age, 59.6% were from urban background and 86.8% were educated; 66% of them had used regular method of contraception some time in their life, but the awareness level of emergency contraceptives was found to be only 5.4% of which only 2% (n=10 had ever used emergency contraceptives. CONCLUSION Emergency contraceptives is an effective means of preventing unwanted pregnancies, but unfortunately majority of women lack awareness about the emergency methods. Efforts should be focused on providing health education regarding EC among females through media and health professionals.

  12. Adequate dosing of micronutrients for different age groups in the life cycle.

    Bienz, Denise; Cori, Hector; Hornig, Dietrich

    2003-09-01

    Many studies of micronutrient supplementation in developing countries have used single-nutrient supplements with either vitamins or minerals. However, people in these countries often suffer from multiple, rather than single, micronutrient deficiencies. The objective of this paper is to discuss the factors that go into determining the adequate dosing of vitamins and/or minerals for people of different ages. To elaborate on the adequacy of micronutrient doses in supplements, a model described by the US FNB was used, which calculates the difference between the mean observed intake for an individual and the estimated average requirement for a life stage and gender group. This model allows estimating the degree of confidence that a certain nutrient intake (from supplements and diet) is adequate. The US/Canadian DRI values have been used as the basis for these calculations, from which it can be concluded that a daily supplement of one RDA of each micronutrient is adequate to cover the personal requirements of all individuals in each respective age and gender group of the population, provided that 20 to 40% of an RDA is supplied by the diet--likely a realistic value for developing countries. DRI values vary significantly between different age groups, reflecting changing needs over a life cycle. With the objective of a supplement to be adequate and safe, the design of a one-for-all supplement covering all age groups is not realistic. Such a supplement would either underscore or surpass the required intake of some of the age groups. Additionally the dosage of certain micronutrients might exceed the upper level of intake for lower age groups. Therefore, it is suggested that three different supplements following the one RDA concept for all micronutrients be developed for research use in developing countries for the following age groups; 1 to 3 years, 4 to 13 years, and females > 14 years (excluding during pregnancy).

    Full Text Available Purpose: to estimate quantitatively factors of somatic component of risk of the development of vegetative-vascular dysfunction at children of the average and advanced school age. Material & Methods: 569 children of 14–17 years old are examined in order to the existence of somatopathies, violation of posture, level and harmony of physical development, extent of development of adipopexis, functional indicators of health. Influence of somatic factors on risk of developing of vegetative-vascular dysfunction was revealed by means of the correlation analysis. Results: the system of assessment and the integrated indicator of action of somatic factors on risk of the development of vegetative-vascular dysfunction are offered. 6,57% of pupils with the low level of probability of risk of developing of vegetative-vascular dysfunction, 24,25% of pupils with the level below the average, 38,36% of children of 14–17 years old with the average level of probability of risk of developing of vegetative-vascular dysfunction, 24,25% of teenagers with the average level of probability, 6,57% of pupils with the high level of probability of risk of developing of vegetative-vascular dysfunction are revealed. The reliable communications between the low level of functionality on the test of Ruffier and the disharmonious physical development (p<0,001, low indicators of power and respiratory indexes (p<0,05 are established statistically. Conclusions: the children of the group of risk, who need the individual approach at lessons of physical culture, are defined.

  15. Average age at death in infancy and infant mortality level: Reconsidering the Coale-Demeny formulas at current levels of low mortality

    Directory of Open Access Journals (Sweden)

    Evgeny M. Andreev

    2015-08-01

    Full Text Available Background: The long-term historical decline in infant mortality has been accompanied by increasing concentration of infant deaths at the earliest stages of infancy. In the mid-1960s Coale and Demeny developed formulas describing the dependency of the average age of death in infancy on the level of infant mortality, based on data obtained up to that time. Objective: In the more developed countries a steady rise in average age of infant death began in the mid-1960s. This paper documents this phenomenon and offers alternative formulas for calculation of the average age of death, taking into account the new mortality trends. Methods: Standard statistical methodologies and a specially developed method are applied to the linked individual birth and infant death datasets available from the US National Center for Health Statistics and the initial (raw numbers of deaths from the Human Mortality Database. Results: It is demonstrated that the trend of decline in the average age of infant death becomes interrupted when the infant mortality rate attains a level around 10 per 1000, and modifications of the Coale-Demeny formulas for practical application to contemporary low levels of mortality are offered. Conclusions: The average age of death in infancy is an important characteristic of infant mortality, although it does not influence the magnitude of life expectancy. That the increase in average age of death in infancy is connected with medical advances is proposed as a possible explanation.

    The objective of this study was to evaluate the associations of variable intensity in rearing dairy heifers on 33 commercial dairy herds, including 23,008 cows and 18,139 heifers, with age at first calving (AFC), average daily weight gain (ADG), and milk yield (MY) level on reproduction traits and profitability. Milk yield during the production period was analyzed relative to reproduction and economic parameters. Data were collected during a 1-yr period (2011). The farms were located in 12 regions in the Czech Republic. The results show that those herds with more intensive rearing periods had lower conception rates among heifers at first and overall services. The differences in those conception rates between the group with the greatest ADG (≥0.800 kg/d) and the group with the least ADG (≤0.699 kg/d) were approximately 10 percentage points in favor of the least ADG. All the evaluated reproduction traits differed between AFC groups. Conception at first and overall services (cows) was greatest in herds with AFC ≥800 d. The shortest days open (105 d) and calving interval (396 d) were found in the middle AFC group (799 to 750 d). The highest number of completed lactations (2.67) was observed in the group with latest AFC (≥800 d). The earliest AFC group (≤749 d) was characterized by the highest depreciation costs per cow at 8,275 Czech crowns (US$414), and the highest culling rate for cows of 41%. The most profitable rearing approach was reflected in the middle AFC (799 to 750 d) and middle ADG (0.799 to 0.700 kg) groups. The highest MY (≥8,500 kg) occurred with the earliest AFC of 780 d. Higher MY led to lower conception rates in cows, but the highest MY group also had the shortest days open (106 d) and a calving interval of 386 d. The same MY group had the highest cow depreciation costs, net profit, and profitability without subsidies of 2.67%. We conclude that achieving low AFC will not always be the most profitable approach, which will depend upon farm

    Coronary artery disease is an extraordinarily common and devastating disorder of middle aged and even young men in the United States and Western Europe. An increasing risk of developing the disease is associated with such factors as high blood pressure, obesity, high levels of cholesterol in the blood serum, cigarette smoking, certain behavioral patterns, decreased vital capacity and a low level of physical activity. There is much evidence to indicate that exercise may well help prevent heart attacks through such mechanisms as increasing heart efficiency, decreasing the level of serum cholesterol, decreasing obesity, decreasing high blood pressure and promoting psychic well-being. It is necessary, however, that the exercise be continued throughout life. Athletic activity in high school or college is of no help in later years. The exercise must be part of a regular scheduled year-round activity. It is suggested that swimming has many unique advantages for such an endeavor. The Amateur Athletic Union of the United States has developed competition in older age groups as a motivating force for the continuance of a regular training program of a healthful nature.

    Heavy fuel oil (HFO) is primarily used as fuel in marine engines and in boilers to generate electricity. Nuclear Magnetic Resonance (NMR) is a powerful analytical tool for structure elucidation and in this study, 1H NMR and 13C NMR spectroscopy were used for the structural characterization of 2 HFO samples. The NMR data was combined with elemental analysis and average molecular weight to quantify average molecular parameters (AMPs), such as the number of paraffinic carbons, naphthenic carbons, aromatic hydrogens, olefinic hydrogens, etc. in the HFO samples. Recent formulae published in the literature were used for calculating various derived AMPs like aromaticity factor 〖(f〗_a), C/H ratio, average paraffinic chain length (¯n), naphthenic ring number 〖(R〗_N), aromatic ring number〖 (R〗_A), total ring number〖 (R〗_T), aromatic condensation index (φ) and aromatic condensation degree (Ω). These derived AMPs help in understanding the overall structure of the fuel. A total of 19 functional groups were defined to represent the HFO samples, and their respective concentrations were calculated by formulating balance equations that equate the concentration of the functional groups with the concentration of the AMPs. Heteroatoms like sulfur, nitrogen, and oxygen were also included in the functional groups. Surrogate molecules were finally constructed to represent the average structure of the molecules present in the HFO samples. This surrogate molecule can be used for property estimation of the HFO samples and also serve as a surrogate to represent the molecular structure for use in kinetic studies.

    We devised this study to quantify the effect of age on the consumption of cisatracurium under general anaesthesia, using a computer controlled closed loop infusion system. We further investigated this effect on, sufentanil and propofol consumption. 74 patients of physical status I and II, requiring general anaesthesia for elective abdominal surgery, were assigned to three groups. Patients in group 1 were aged from 20 to 45, group 2 were from 46 to 64, and group 3 above 65 years old. General Anesthesia was maintained with propofol and muscle paralysis was maintained using a closed-loop computer controlled infusion of cisatracurium. For analgesia, intermittent bolus of sufentanil 10 μg was given. Cisatracurium consumption in group 1, 2 and 3 were 1.8 ± 0.3, 1.6 ± 0.4 and 1.3 ± 0.4 μg/kg/min respectively. There was significant difference of cisatracurium consumption between group 1 and 3 (P = 0.002), and the consumption of cisatracurium in group 3 was less as compared with group 2 (P = 0.04). The average recovery index of patients in group 1, 2 and 3 were 8.8 ± 2.6, 11.5 ± 2.9 and 12.7 ± 2.5 minutes respectively. There were difference between group 1 and 2 (P = 0.02). As compared with group 1, the recovery index was still longer in group 3 (P = 0.001). Patients in group 1, 2 and 3 consumed an average sufentanil 0.4 ± 0.1, 0.4 ± 0.1 and 0.3 ± 0.1 μg/kg/hr, respectively. There were statistical significant between group 1 and 3 (P < 0.0001), and the same trend was found between group 2 and 3 (P = 0.03). The Consumption of propofol in group 1, 2 and 3 were 5.1 ± 0.4, 4.3 ± 0.6 and 3.1 ± 0.5 mg/kg/hr. The difference in the propofol consumption was found statistically significant when comparing between any two groups. We concluded that the sensitivity of anesthetic agents increased with age. Less medication was required to achieve a desirable effect in older patients specially those

    Type 1 diabetes (T1D) is one of the most common chronic childhood diseases and its incidence has doubled during the last decade. The goals of intensive management of diabetes were established in 1993 by the Diabetes Control and Complications Trial (DCCT) (1). Children with T1D and their caregivers continue to face the challenge to maintain blood glucose levels in the near-normal range. It is important to prevent sustained hyperglycaemia which is associated with long-term microvascular and macrovascular complications and to avoid recurrent episodes of hypoglycaemia or hyperglycaemia, especially in young children, which may have adverse effects on cognitive function and impede efforts to achieve the recommended glycaemic targets. Advances in the use of technology that may help maintain the metabolic control goals for young people with T1D were centred on continuous subcutaneous insulin infusion (CSII) (2-4), continuous glucose monitoring (CGM) (5-7), and combining both technologies into a closed-loop system (8-10). The dilemma in paediatrics of patient selection for insulin pump therapy was found to be most successful in those with more frequent self-monitoring of blood glucose (SMBG) and younger age prior to pump initiation (2). Similarly, those who used a dual-wave bolus probably paid closer attention to their management and had lower HbA1c levels (3). The advantage of using a pre-meal bolus to improve postprandial glucose levels was shown to offer another potential method to improve glycaemic control (4). SMBG is an important component of therapy in patients with diabetes, especially in the paediatric age group. Standard use of glucose meters for SMBG provides only intermittent single blood glucose levels, without giving the 'whole picture' of glucose variability during the 24 h, and especially during the night, when blood glucose levels are seldom measured. Therefore, the use of a device such as real-time continuous glucose monitoring (RT-CGM) that provides

    To estimate the incidence of disc displacement, disc deformity, and bone changes of the temporomandibular joint in elderly patients with temporomandibular disorders, 55 elderly patients (110 joints) were examined by magnetic resonance imaging. The ages of the patients ranged from 65 to 89 years (average, 70 years). They consisted of 13 men and 42 women. Normal disc position was found in 40 joints (36.4%), anterior disc displacement with reduction in 17 joints (15.5%), and anterior disc displacement without reduction in 53 joints (48.2%) on magnetic resonance imaging. Thirty-eight (71.6%) of the 53 joints with anterior disc displacement without reduction had disc deformity and 33 (62.3%) had bone changes. The frequency of bone changes in the elderly group was higher than that in the younger group. Women had a higher incidence of bone changes than men. (author)

    Full Text Available Objectives: The aim of this study was to characterize tinnitus in affected patients. Methods: A retrospective review of medical records from 470 consecutive patients who visited a tertiary care hospital for evaluation of chronic subjective tinnitus between January 2009 and June 2010 was performed. Patients were divided into three subgroups based on age. Clinical, audiological, and psychological characteristics of each subgroup were analyzed. Results: Of the 470 patients evaluated, 85 were less than 40, 217 between 40 and 60, and 168 above 60 years of age. Most patients were men and complained of unilateral, acute high-pitched tinnitus. Most patients above the age of 40 years complained of loud and annoying tinnitus and had worse stress and severity scores. Conclusions: Chronic tinnitus in older adults is subjectively louder, more annoying, and more distressing than that found in younger patients. We recommend considering age in the patient management plan.

    Full Text Available Age (and its changing structure amongst the wider population is one of the most relevant aspects required to better understand and forecast the needs, interests and associated consumption behaviours of tourists. This research used age to investigate the expenditure patterns amongst a sample of visitors to the Table Mountain National Park (TMNP, South Africa. In March 2010, visitors to the TMNP were found to differ significantly from those at other parks, as they were younger and most of them were foreigners. This study found that younger visitors (18–29 years were higher spenders when compared to those aged 30–49 years. As parks are generally visited by older people, this study showed the economic importance of the younger market. The research also made clear implications and recommendations for park management as to how to address these findings. Conservation implications: Conservation is dependent on funding. One of the main sources of income is tourism and tourism related activities. This research can assist marketers and managers to target the right markets in order to be more sustainable. This research also shows the importance of environmental education at an early age in order to grow awareness and to target the right markets.

    Laboratory social stress tests involving public speaking challenges are widely used for eliciting an acute stress response in older children, adolescents, and adults. Recently, a group protocol for a social stress test (the Trier Social Stress Test for Groups, TSST-G) was shown to be effective in adults and is dramatically less time-consuming and resource-intensive compared to the single-subject version of the task. The present study sought to test the feasibility and effectiveness of an adapted group public speaking task conducted with a racially diverse, urban sample of U.S. adolescents (N=191; 52.4% female) between the ages of 11 and 18 (M=14.4 years, SD=1.93). Analyses revealed that this Group Public Speaking Task for Adolescents (GPST-A) provoked a significant increase in cortisol production (on average, approximately 60% above baseline) and in self-reported negative affect, while at the same time avoiding excessive stress responses that would raise ethical concerns or provoke substantial participant attrition. Approximately 63.4% of participants exhibited an increase in cortisol levels in response to the task, with 59.2% of the total sample showing a 10% or greater increase from baseline. Results also suggested that groups of five adolescents might be ideal for achieving more uniform cortisol responses across various serial positions for speech delivery. Basal cortisol levels increased with age and participants belonging to U.S. national minorities tended to have either lower basal cortisol or diminished cortisol reactivity compared to non-Hispanic Whites. This protocol facilitates the recruitment of larger sample sizes compared to prior research and may show great utility in answering new questions about adolescent stress reactivity and development.

    Distance based clustering algorithms can group genes that show similar expression values under multiple experimental conditions. They are unable to identify a group of genes that have similar pattern of variation in their expression values. Previously we developed an algorithm called divisive correlation clustering algorithm (DCCA) to tackle this situation, which is based on the concept of correlation clustering. But this algorithm may also fail for certain cases. In order to overcome these situations, we propose a new clustering algorithm, called average correlation clustering algorithm (ACCA), which is able to produce better clustering solution than that produced by some others. ACCA is able to find groups of genes having more common transcription factors and similar pattern of variation in their expression values. Moreover, ACCA is more efficient than DCCA with respect to the time of execution. Like DCCA, we use the concept of correlation clustering concept introduced by Bansal et al. ACCA uses the correlation matrix in such a way that all genes in a cluster have the highest average correlation values with the genes in that cluster. We have applied ACCA and some well-known conventional methods including DCCA to two artificial and nine gene expression datasets, and compared the performance of the algorithms. The clustering results of ACCA are found to be more significantly relevant to the biological annotations than those of the other methods. Analysis of the results show the superiority of ACCA over some others in determining a group of genes having more common transcription factors and with similar pattern of variation in their expression profiles.

    Lesbian, gay, bisexual, and transgender (LGBT) people are a health disparate population as identified in Healthy People 2020. Yet, there has been limited attention to how LGBT older adults maintain successful aging despite the adversity they face. Utilizing a Resilience Framework, this study investigates the relationship between physical and mental health-related quality of life (QOL) and covariates by age group. A cross-sectional survey of LGBT adults aged 50 and older (N = 2,560) was conducted by Caring and Aging with Pride: The National Health, Aging, and Sexuality Study via collaborations with 11 sites across the U.S. Linear regression analyses tested specified relationships and moderating effects of age groups (aged 50-64; 65-79; 80 and older). Physical and mental health QOL were negatively associated with discrimination and chronic conditions and positively with social support, social network size, physical and leisure activities, substance nonuse, employment, income, and being male when controlling for age and other covariates. Mental health QOL was also positively associated with positive sense of sexual identity and negatively with sexual identity disclosure. Important differences by age group emerged and for the old-old age group the influence of discrimination was particularly salient. This is the first study to examine physical and mental health QOL, as an indicator of successful aging, among LGBT older adults. An understanding of the configuration of resources and risks by age group is important for the development of aging and health initiatives tailored for this growing population. © The Author 2014.

    Patients with vaginitis were classified into four groups: Group A (prepubertal under-aged females); Group B (pubertal under-aged females); Group C (reproductive age adult females); Group D (postmenopausal adult females). All vaginal specimens underwent microscopy, amine testing, Gram staining and culturing. Overall, 163 patients were included (33, 14, 81 and 35 patients, respectively). The most common infection was bacterial vaginosis (BV), followed by Ureaplasma infection, aerobic vaginitis (AV) and candidiasis. The most common AV-associated organism was Escherichia coli and the most common BV-associated organism was Gardnerella vaginalis. AV was more frequent in Group A, BV in Group C and Ureaplasma infections in Groups C/D. Decreased lactobacilli concentrations were associated with BV in fertile patients (Groups B-C). Although presentation of vaginitis is similar among females of different age in Greece, type and prevalence of pathogens differ. Normal vaginal flora changes are associated with higher risk of vaginitis in specific age groups. Impact Statement The worldwide incidence of reproductive tract infections has been increasing, with specific pathogens being associated with significant risk of morbidity and complications. However, literature data on the distribution of such infections in different age groups is limited. Therefore, the aim of this study was to provide data on the prevalence and causes of vaginitis in adult and non-adult females of all ages. This study has shown that although presentation of vaginitis is similar among females of different age groups and menstrual status in Greece, type and prevalence of responsible pathogens are different among groups. Changes in normal vaginal flora seem to be associated with higher risk of vaginitis in specific age-groups as well. These findings could contribute in adjusting diagnostic and therapeutic strategies for each age group according to the prevailing pathogens. Further research on antibiotic

    Full Text Available Pediatric age is the most important period for preventive eye care services and research. Vision loss in this period could cause a long life without sight and also significant financial and moral losses, in terms of people and society. Rational screening programs may reduce vision loss in childhood and this issue increases the value of the subject. Retinopathy of prematurity, congenital/infantile cataracts and glaucoma, optic nerve and retinal pathologies, refractive errors, amblyopia, and strabismus are the major clinical pictures causing visual loss in childhood. Using the epidemiological data, it could be estimated that every year approximately two to three thousand children suffer an ophthalmologic disease that causes significant visual loss. Regarding the refractive errors and amblyopia, it could be estimated that hundreds of thousands of children need ophthalmological follow-up in the country. For the timely treatment of these pathologies, a couple of short eye examination programs seem more realistic. Childhood vision loss in the country could be reduced, by informing pediatricians and family physicians and by proper guiding of the public opinion. Effective eye screening could be achieved with the implementation of simple methods like red reflex/Brückner test with ophthalmoscopy, or simultaneous (binocular retinoscopy and ophthalmoscopy of both eyes. Screening programs could be spread throughout the country by appropriate training of the physicians in the health institutions of the country. Screening programs will contribute to reduce the rate of visual disability by disseminating ophthalmologic practices throughout the country. (Turk J Ophthalmol 2013; 43: 195-201

    To study the effect of obesity on pulmonary function in newly diagnosed asthmatic children of different age groups. Two hundred and ninety-four children with newly diagnosed asthma were classified into preschool-age (obese, overweight, and normal-weight subgroups based on their body mass index (BMI). All the children underwent pulmonary function tests, including large airway function tests [forced vital capacity (FVC%) and forced expiratory volume in one second (FEV1%)] and small airway function tests [maximal expiratory flow at 25% of vital capacity (MEF25%), maximal expiratory flow at 50% of vital capacity (MEF50%), and maximal expiratory flow at 75% of vital capacity (MEF75%)]. The school-age group showed lower FEV1%, MEF25%, and MEF50% than the preschool-age group (Pchildren in the school-age group had lower FEV1%, MEF25%, and MEF50% compared with their counterparts in the preschool-age group (Pchildren in the school-age group showed lower FVC% and MEF50% than those in the preschool-age group. However, all the pulmonary function parameters showed no significant differences between the obese children in the preschool-age and school-age groups. In the preschool-age group, FVC%, FEV1%, and MEF75% of the obese children were lower than those of the normal-weight children. In the school-age group, only FVC% and FEV1% showed differences between the obese and normal-weight children (Pobesity on the pulmonary function varies with age in children with asthma, and the effect is more obvious in those of preschool age.

    Full Text Available Purpose. Studying the peculiarities of the genetic structure of different age groups of silver and bighead carps from fish farm Limanske with the use of genetic-biochemical markers. Methodology. The methods of vertical polyacrylamide and horizontal starch electrophoresis with our own modifications have been used for the study. Sampling of the biological material and histochemical staining of gel plates were carried out using the generally accepted methods. Statistical analysis of the obtained data were performed in "Biosys-I". Findings. We analyzed the genetic structure of age-1, age-1+ and age-2 of silver and bighead carps with the use of genetic-biochemical markers - Рralb, EST, MDH, МЕ, СА. We demonstrated the peculiarities of allele frequencies and genotypic composition of protein system loci. A high level of heterozygosity in the examined was detected loci for age-1 silver carp – 66.7-88.9% and age-1 bighead carp – 65.4-77.8%. A significantly higher level of the observed average heterozygosity compared to the expected heterozygosity of age-1 as silver carp (Ho = 75.9%, He = 49,6%, and bighead carp (Ho = 73,6%, He = 47,9% was observed. This fact indicated on the necessity for performing a stabilization of their genetic structure. The calculated Wright's F index in different age groups showed a predominance of the observed level of the average heterozygosity over the expected one for 22.7–53% in silver carp and 24.5-53.7% in bighead carp. A stabilization of the genetic structure in age-2 silver carp (Ho = 57.8%; He = 47.1% by the heterogeneity level was observed. Originality. For the first time we analyzed the genetic structure and the level of heterogeneity of the breeding groups of age-1, age-1+, age-2 silver and bighead carps from fish farm Limanske with the use of genetic-biochemical markers. Practical value. The results of the study can be used in selection and breeding works aimed at creating the breeding stocks of silver and

    Full Text Available More than half of the adult population of the Republic of Serbia is overweight or obese. Obesity carries various risks and general health complications, which can significantly impair one's functioning and well-being. On the other hand, beneficial effects of body mass reduction are clearly confirmed. The therapeutic approach to obesity involves the use of various measures Treatment may include: medical nutrition therapy, programmed physical activity, medicaments and surgical treatment. The aim of this study was to examine if the effectiveness of medical nutrition therapy depends on the sex and age structure. This investigation was conducted as a retrospective study for the period from January 2008. until July 2009. During this time, 990 people came to the Counceling center. Only patients who came regularly to the controls and had BMI higher than 25 kg/m2 were included in this study. The average BMI in men was 31.55 kg/m2 and 32.66 kg/m2 in women. Compared to the first examination, majority of females (n = 35, 24.56% and males (n = 23, 25.27% reduced their BMI from 0 to 0.5 kg/m2 after medical nutrition therapy. Based on the results of X2 test, we concluded that there were statistically significant differences between men and women in effectiveness of medical nutrition therapy, while differences in the effectiveness of treatment in different age groups do not exist, neither in men nor in women.

    Full Text Available Background and Objectives: Few studies have been conducted to explore eating behavior and weight concern among middle-aged women. Methods: Participants were a sample of 236 Chinese women aged 30-52. Outcome measures were various symptoms related to eating disorders, the weight concern and psychological characteristics subscales of the Eating Disorder Inventory-2 questionnaire (EDI-2. Independent variables were age, education level and BMI. ANOVA-Test and Linear Regression were performed. Results: A group of women (N = 132, 78% with normal weight (19 < BMI < 24 showed dissatisfaction with their weight and wanted to reduce it. Overweight and obese women scored significantly higher on the subscale Body Dissatisfaction on the EDI-2 than women with lower BMI. In comparison to the older group (50-59, the younger group (30-39 and middle-aged group (40-49 expressed the desire to lose weight with a lower BMI. Conclusions: In comparison to age, the BMI had a stronger impact on the psychological and behavioral traits related to the eating disorders among a group of middle-aged Chinese women.

    Full Text Available Working memory is vulnerable to age-related decline, but there is debate regarding the age-sensitivity of different forms of spatial-sequential working memory task, depending on their passive or active nature. The functional architecture of spatial working memory was therefore explored in younger (18-40 years and older (64-85 years adults, using passive and active recall tasks. Spatial working memory was assessed using a modified version of the Spatial Span subtest of the Wechsler Memory Scale – Third Edition (WMS-III; Wechsler, 1998. Across both age groups, the effects of interference (control, visual, or spatial, and recall type (forward and backward, were investigated. There was a clear effect of age group, with younger adults demonstrating a larger spatial working memory capacity than the older adults overall. There was also a specific effect of interference, with the spatial interference task (spatial tapping reliably reducing performance relative to both the control and visual interference (dynamic visual noise conditions in both age groups and both recall types. This suggests that younger and older adults have similar dependence upon active spatial rehearsal, and that both forward and backward recall require this processing capacity.

Specifically the backward recall task was significantly predicted by age, within both the younger and older adult groups. This finding supports previous literature showing lifespan linear declines in spatial-sequential working memory, and in working memory tasks from other domains, but contrasts with previous evidence that backward spatial span is no more sensitive to aging than forward span.

    Full Text Available The aim of this study was to improve knowledge on the effect of group size on productive performance and egg quality of hens raised in furnished cages equally designed. A total of 520, 15-week-old Lohmann Brown laying hens were divided into 2 groups to have a similar initial body weight (average 1392±16.3 g. The cages of S25 group (240 L x 78 W x 50 H cm, 749 cm2/hen hosted a total of 200 hens, while those of S40 group (462 L x 65 W x 50 H, 751 cm2/hen included 320 birds. Experimental data were recorded after an adaptation period of 5 weeks (20 to 36 weeks of age. Hens were submitted to 15 h of light/d. The average temperature inside the building was 24.6±2.5°C over the entire experimental period with higher values at 24, 26, 28 and 30 weeks of age. The relative humidity recorded inside the building was 55% at week 20 and 60% all through the experimental period. Hens raised from S40 group had lower percentage of egg production (84.91 vs 88.90%, P<0.01 and higher feed conversion ratio (2.70 vs 2.25, P<0.0001 than S25 group. The percentage of eggs laid out of the nest was higher in S25 than S40 group (0.26 vs 0.19%, P<0.01. As expected, the week of age affected almost all the parameters (feed intake, body weight, laying percentage, egg weight, yolk, shell and albumen indexes, shell thickness, Haugh unit. However, the effect of group size was particularly evident during the hot period.

    Demodex folliculorum and Demodex brevis were looked for on eyelashes sampled from 481 people, aged 3 through 96. The persons studied were divided into 9 age groups. Magnitude of the infection symptoms was assessed based on macroscopic changes of eye-lid edges and on interviews with patients. An increase of the prevalence of infection and intensification of the symptoms were observed to coincide with the age increase of the persons studied. No significant differences were demonstrated between the infection frequencies of women and men. Symptoms of ocular demodecosis were more frequent only in women of group III (aged 21-30) and group V (41-50) (p < 0.05).

    The religious landscape of older adults around the world is changing profoundly. Yet until now, no study has chronicled these changes or compared expected aging patterns of religious groups. Differential aging among religious groups can have important economic and social consequences. This study estimates and projects the future religious composition by age at the global and regional levels. This study presents estimates of age structures by religion for 2010 and projections until 2050. It is based on analyses of more than 2,500 censuses, registers, and surveys from 198 countries. Regional and global results are the aggregate of demographic projections carried out at the country level. In 2010, Muslims were least likely to be aged 60 or older (7% of all Muslims), and Jews were most likely to be in this age group (20% of all Jews). By 2050, we project that Buddhists and the religiously unaffiliated will have the oldest populations (both will have 32% above the age of 60), whereas Muslims will remain the youngest religious group (with only 16% above the age of 60). Christians will, globally, age relatively slowly, from 14% to 21% above the age of 60 from 2010 to 2050. The religious landscape among the world's seniors will change fundamentally in the coming years, due to the combination of rapid aging among the religiously unaffiliated and Buddhist populations and the persistence of relatively young age structures among Muslims and Christians, which are the dominant religions in Africa.

    This study compared the accuracy of physical activity energy expenditure (PAEE) prediction using two methods of accounting for age dependency versus one standard (single) value across all ages. PAEE estimates were derived by pooling data from five studies. Participants, 6-18 years (n=929), engaged in 14 activities while in a room calorimeter or wearing a portable metabolic analyzer. Linear regression was used to estimate the measurement error in PAEE (expressed as METy) associated with using age-groups (6-9, 10-12, 13-15, and 16-18 years) and age-in-years (each year of chronological age (e.g., 12=12.0-12.99 years)) versus the standard (a single value across all ages). Age-groups and age-in-years showed similar error, and both showed less error than the standard method for cycling, skilled and moderate-to-vigorous intensity activities. For sedentary and light activities, the standard had similar error to the other two methods. Mean values for root mean square error ranged from 0.2-1.7 METy across all activities. Error reduction ranged from -0.2-21.7% for age-groups and -0.23-18.2% for age-in-years, compared to the standard. Accounting for age showed lower errors than a standard (single) value; using an age-dependent model in the Youth Compendium is recommended.

  6. AGE GROUPS OF ANTARCTIC KRILL,EUPHAUSIA SUPERBA DANA,IN THE PRYDZ BAY REGION

    Age groups of Antarctic krill (Euphausia superba Dana) in the Prydz Bay region were studied by distribution mixture analysis based on length/frequency data collected by R/V Jidi during the 1989/1990 and 1990/1991 austral summer. Five age groups were determined, i.e. 1+, 2+, 3+, 4+, and 5+ , or six age groups in all, if the 0+ larvae were included. The mean body length of 1+ to 5+ age groups was 25.70 mm, 40.47 mm, 45.52 mm, 50.52 mm and 54.52 mm respectively. Supposing the difference in body length between successive age groups is a reflection of the yearly growth, the maximum growth rate occurred during the period from 1+ juveniles to 2+ subadults (14.77 mm/a). From 2+ subadults to 3+ adults the growth rate dropped steeply (5.05 mm/a) because at this stage, increase of body length was substituted, to a great extent, by the growth of sexual products. From 3+ onwards the growth rate was maintained at a relatively low level and decreased slowly with age. The relative abundance of age groups 1+ and 2+, in our sample must be much lower than that in the real population owing to both the large mesh size we used and the distribution difference between juveniles and adults. If we left aside 1+ and 2+ age groups and just looked at the relative abundance of adults, we found that age group 3+ dominated the adult population and that the relative abundance decreased sharply with increasing age. If this situation is normal, one can expect an extremely high mortality rate in adults, 82.6% from 3+ to 4+ and 94.0% from 4+ to 5+. This is reasonably expectable for the Prydz Bay region.

    Understanding adverse event patterns in clinical studies across populations is important for patient safety and protection in clinical trials as well as for developing appropriate drug therapies, procedures, and treatment plans. The objective of our study was to conduct a data-driven population-based analysis to estimate the incidence, diversity, and association patterns of adverse events by age of the clinical trials patients and participants. Two aspects of adverse event patterns were measured: (1) the adverse event incidence rate in each of the patient age groups and (2) the diversity of adverse events defined as distinct types of adverse events categorized by organ system. Statistical analysis was done on the summarized clinical trial data. The incident rate and diversity level in each of the age groups were compared with the lowest group (reference group) using t tests. Cohort data was obtained from ClinicalTrials.gov, and 186,339 clinical studies were analyzed; data were extracted from the 17,853 clinical trials that reported clinical outcomes. The total number of clinical trial participants was 6,808,619, and total number of participants affected by adverse events in these trials was 1,840,432. The trial participants were divided into eight different age groups to support cross-age group comparison. In general, children and older patients are more susceptible to adverse events in clinical trial studies. Using the lowest incidence age group as the reference group (20-29 years), the incidence rate of the 0-9 years-old group was 31.41%, approximately 1.51 times higher (P=.04) than the young adult group (20-29 years) at 20.76%. The second-highest group is the 50-59 years-old group with an incidence rate of 30.09%, significantly higher (Pdata suggest that age-associated adverse events should be considered in planning, monitoring, and regulating clinical trials.

    A newly discovered fossil assemblage including trilobite, ostracod, bryozoan, and microcrinoid fragments and agglutinated foraminifers has been found in the Wilhite Formation, Walden Creek Group, Ocoee Supergroup, in the foothills of the Great Smoky Mountains, Tennessee. These fossils prove a Paleozoic age for the Walden Creek Group, which had been interpreted to be of Late Proterozoic age. The foraminiferal assemblage indicaes the Silurian as the older age limit for the Walden Creek Group. These findings make necessary a redefinition of the Ocoee sedimentary basin and reinterpretation of models of the evolution of the Blue Ridge structural province.

    Full Text Available In recent years, there have been requirments for a transport environment that will foster the development of safe, comfortable townships. The study of urban activities amid an aging society and effective use of public transport modes in addressing environmental problems have become particularly important issues. This study analyzes travel behaviour patterns of varying age groups using urban railways in order to examine the relationship between urban public transport use and urban activities. specifically, it analyzes the composition of urban activity and travel behaviour patterns among urban railway users in the Keihanshin (Kyoto-Osaka-Kobe metropolitan area. This paper looks at urban activities within aging societies and identifies the differences in travel behaviour of railway users by separating them into young, middle aged and senior citizen age groups. Analysis makes particular use of the Railway station Database, which is a compilation of existing studies into attributes of railway stations and their surroundings, and results of person trip surveys. Rail use behaviour characteristics have been sorted by age group because mobility via urban railway systems is varied by age group. As a result, differences in railway usage patterns (travel objectives, distance and time, and number of transfers, etc. have been identified and so too have differences in urban activity patterns related to free activities (shopping, recreation. Furthermore, the study developed a travel behaviour pattern estimation model which is capable of categorizing specific transport behaviour patterns and estimating rail users and transport behaviour patterns from the relationship with areas surrounding railway stations to ensure future mobility by public transport for older age groups. The results make it possible to put forward proposals for urban rail services that will facilitate urban activities for the different age groups. Eventually, it will be possible to understand

    In this report we assess the systolic maximal flow velocity in carotid and intracranial arteries in 191 subjects with no history of cerebral vascular disease in 3 age groups: 20-40 years (1 group), 41-60 years (2 group), and above 60 years (3 group). The subjects were assessed using Sonomed Transcranial Doppler Spectrograph according to generally accepted principles. The purpose of the study was to establish the mean value of maximal flow velocity in each particular artery in three age groups, and to observe the changes in this parameter with age. The results were analyzed using statistical methods and a significant decrease in blood flow, Vmax, was found in all investigated arteries. A mean decrease of 8.02% in flow velocity Vmax was found, when comparing groups 2 and 1, and difference 15.99% comparing 3 and 1.

    Full Text Available Introduction: Patients with obstructive sleep apnea syndrome usually present with changes in upper airway morphology and/or body fat distribution, which may occur throughout life and increase the severity of obstructive sleep apnea syndrome with age. Objective: To correlate cephalometric and anthropometric measures with obstructive sleep apnea syndrome severity in different age groups. Methods: A retrospective study of cephalometric and anthropometric measures of 102 patients with obstructive sleep apnea syndrome was analyzed. Patients were divided into three age groups (≥20 and <40 years, ≥40 and <60 years, and ≥60 years. Pearson's correlation was performed for these measures with the apnea-hypopnea index in the full sample, and subsequently by age group. Results: The cephalometric measures MP-H (distance between the mandibular plane and the hyoid bone and PNS-P (distance between the posterior nasal spine and the tip of the soft palate and the neck and waist circumferences showed a statistically significant correlation with apnea-hypopnea index in both the full sample and in the ≥40 and <60 years age group. These variables did not show any significant correlation with the other two age groups (<40 and ≥60 years. Conclusion: Cephalometric measurements MP-H and PNS-P and cervical and waist circumfer- ences correlated with obstructive sleep apnea syndrome severity in patients in the ≥40 and <60 age group.

    Age has been included in various prognostic scoring systems for differentiated thyroid cancer (DTC). The aim of this study is to re-examine the relationship between age and prognosis by using Surveillance, Epidemiology, and End Results (SEER) population-based database. We identified 51,061 DTC patients between 2004 and 2012. Patients were separated into 10-year age groups. Cancer cause-specific survival (CSS) and overall survival (OS) data were obtained. Kaplan-Meier and multivariable Cox models were built to analyze the outcomes and risk factors. Increasing age gradient with a 10-year interval was associated with the trend of higher proportions for male gender, grade III/IV and summary stage of distant metastases. Both CSS and OS continued to worsen with increasing age, being poorest in in the oldest age group (≥71); multivariate analysis confirmed that CSS continued to fall with each age decade, significantly starting at 60 years (HR = 7.5, 95% 1.0–54.1, p = 0.047) compared to the young group (≤20). Similarly, multivariate analysis suggested that OS continued worsening with increasing age, but starting at 40 years (HR = 3.7, 95% 1.4–10.1, p = 0.009) compared to the young group. The current study suggests that an age exceeding 60 years itself represents an unfavorable prognostic factor and high risk for cancer-specific death in DTC. PMID:27272218

  16. A self-consistent, absolute isochronal age scale for young moving groups in the solar neighbourhood

    2015-11-01

    We present a self-consistent, absolute isochronal age scale for young ( ≲ 200 Myr), nearby ( ≲ 100 pc) moving groups in the solar neighbourhood based on homogeneous fitting of semi-empirical pre-main-sequence model isochrones using the τ2 maximum-likelihood fitting statistic of Naylor & Jeffries in the MV, V - J colour-magnitude diagram. The final adopted ages for the groups are as follows: 149^{+51}_{-19} {Myr} for the AB Dor moving group, 24 ± 3 Myr for the β Pic moving group (BPMG), 45^{+11}_{-7} {Myr} for the Carina association, 42^{+6}_{-4} {Myr} for the Columba association, 11 ± 3 Myr for the η Cha cluster, 45 ± 4 Myr for the Tucana-Horologium moving group (Tuc-Hor), 10 ± 3 Myr for the TW Hya association and 22^{+4}_{-3} {Myr} for the 32 Ori group. At this stage we are uncomfortable assigning a final, unambiguous age to the Argus association as our membership list for the association appears to suffer from a high level of contamination, and therefore it remains unclear whether these stars represent a single population of coeval stars. Our isochronal ages for both the BPMG and Tuc-Hor are consistent with recent lithium depletion boundary (LDB) ages, which unlike isochronal ages, are relatively insensitive to the choice of low-mass evolutionary models. This consistency between the isochronal and LDB ages instils confidence that our self-consistent, absolute age scale for young, nearby moving groups is robust, and hence we suggest that these ages be adopted for future studies of these groups.

    Full Text Available BACKGROUND: muscle strength and power are two factors affecting balance. The impact of muscle strength and power on postural control has not been fully explored among different age strata over sixty. OBJECTIVES: the aim of the present study was to assess the muscle strength and power of elderly women in different age groups and determine their correlation with postural control. METHOD: eighty women were divided into four groups: the young 18-30 age group (n=20; the 60-64 age group (n=20; the 65-69 age group (n=20; and the 70-74 age group (n=20. The participants underwent maximum strength (one repetition maximum or 1-RM and muscle power tests to assess the knee extensor and flexor muscles at 40%, 70%, and 90% 1-RM intensity. The time required by participants to recover their balance after disturbing their base of support was also assessed. RESULTS: the elderly women in the 60-64, 65-69, and 70-74 age groups exhibited similar muscle strength, power, and postural control (p>0.05; however, these values were lower than those of the young group (p<0.05 as expected. There was a correlation between muscle strength and power and the postural control performance (p<0.05. CONCLUSION: despite the age difference, elderly women aged 60 to 74 years exhibited similar abilities to generate strength and power with their lower limbs, and this ability could be one factor that explains the similar postural control shown by these women.

    Loriaux, M

    1995-01-01

    The consequences of demographic aging in developed societies are examined. The author notes that "demographic aging has intensified over the last decades, bringing with it a significant modification in relationships between age groups and the sexes.... These changes in demographic structures bring with them the reorganization in intergenerational relations, the most spectacular instance of which...[is] the coexistence at the same time and in the same place of four or five generations of direct descendants." The author develops the hypothesis that a new attitude toward old age is needed in which "the social status of the elderly must be reinstated, and everything must be brought into play to encourage the integration of different age groups and intergenerational solidarity, so as to arrive in the best possible conditions at what [can be termed] the 'era of old age'...which will accompany the coming of the post-industrial society with its orientation toward the mass production of leisure and of services."

    A cross sectional descriptive study was designed to find out the difference in weight of the thyroid gland of Bangladeshi people in relation to age and sex. The present study was performed on 70 post mortem human thyroid gland (35 of male and 35 of female) collected from the morgue in the Department of Forensic Medicine, Mymensingh Medical College, Mymensingh by purposive sampling technique. The specimens were collected from Bangladeshi cadavers of age ranging from 10 years to 85 years. All the specimens were grouped into three categories Group A (upto 20 years), Group B (21 to 50 years) and Group C (>50 years) according to age. Dissection was performed according to standard autopsy techniques. The weight of the thyroid glands were measured and recorded. The mean weight of the thyroid gland was 6.94 ± 5.20 gm in Group A, 7.91 ± 5.89 gm in Group B and 10.42 ± 6.27 gm in Group C. The mean weight of the thyroid gland in male was 7.0 ± 5.77 gm in Group A, 9.94 ± 7.63 gm in Group B and 11.89 ± 5.73 gm in Group C and in female was 6.88 ± 4.88 gm in Group A, 5.88 ± 2.15 gm in Group B and 9.10 ± 6.74 gm in Group C. Variance analysis shows that there was no significant difference in mean weight between the Age Group A & B, B & C and C & A. There was significant difference of weight of thyroid gland between sex in age Group B but in Group A and Group C were statistically insignificant. The weight of the thyroid gland was found to increases with age. In statistical analysis, differences between age groups were analyzed by using one way ANOVA test. The present study will help to increase the information pool on the weight of thyroid gland of Bangladeshi people.

    Four new SHRIMP U-Pb zircon ages older than 93 Ma from samples of the two uppermost formations accumulated in two different depocenters (Golfo de San Jorge and Cañadón Asfalto basins) of the Chubut Group in central Argentinean Patagonia, establish a pre-late Cenomanian-? early Turonian age for the group. It also confirms a coeval and comparable evolution of the two depocenters, where distal pyroclastic material was deposited together with fluvial and lacustrine facies.

    This paper presented the lesson of setting up a false immunization priority age group for leptospirosis which failed to prevent the leptospirosis outbreak. Our experience was that in the rice paddy field type endemic area the priority age group for the vaccination against leptopirosis should be 15 to 34 year olds followed by 35 years old or above. There was no preventive effect in the vaccination for the children 14 years old or yaunger, to our observation.

The number of female finishers increased (r2 = 0.64, P = 0.001, whereas the number of male finishers (r2 = 0.18, P = 0.15 showed no change. The annual top ten men became older and slower, whereas the annual top ten women became older but not slower. Regarding the number of finishers in the age groups, the number of female finishers decreased in the age group 18–24 years, whereas the number of finishers increased in the age groups 30–34, 40–44, 45–49, 50–54, 55–59, 60–64, and 70–74 years. In the age groups 25–29 and 35–39 years, the number of finishers showed no changes across the years. In the age group 70–74 years, the increase in number of finishers was linear. For all other age groups, the increase was exponential. For men, the number of finishers decreased in the age groups 18–24, 25–29, 30–34, and 35–39 years. In the age groups 40–44, 45–49, 50–54, 55–59, 60–64, 70–74, and 75–79 years, the number of finishers increased. In the age group 40–44 years, the increase was linear. For all other age groups, the

    There is limited information on the roles of different age groups during pertussis outbreaks. Little is known about vaccine effectiveness against pertussis infection (both clinically apparent and subclinical), which is different from effectiveness against reportable pertussis disease, with the former influencing the impact of vaccination on pertussis transmission in the community. For the 2012 pertussis outbreak in Minnesota, we estimated odds ratios for case counts in pairs of population groups before vs. after the epidemic's peak. We found children aged 11-12y, 13-14y and 8-10y experienced the greatest rates of depletion of susceptible individuals during the outbreak's ascent, with all ORs for each of those age groups vs. groups outside this age range significantly above 1, with the highest ORs for ages 11-12y. Receipt of the fifth dose of DTaP was associated with a decreased relative role during the outbreak's ascent compared to non-receipt [OR 0.16 (0.01, 0.84) for children aged 5, 0.13 (0.003, 0.82) for ages 8-10y, indicating a protective effect of DTaP against pertussis infection. No analogous effect of Tdap was detected. Our results suggest that children aged 8-14y played a key role in propagating this outbreak. The impact of immunization with Tdap on pertussis infection requires further investigation.

    This study investigated the cultural and age effects on children's overall creativity and drawing. 1,055 children ages 6 to 8 from three groups--urban and rural Taiwanese children and Taiwanese children of immigrant mothers, all in public schools--were given a creativity test, a people-drawing test, and a free-drawing test. The results showed that the older Taiwanese children scored higher than the young Taiwanese children on people-drawing and free-drawing, but not overall creativity. Drawing and creativity scores increased in accordance with age. In the six-year-old group, a group difference was found only on the scale of people-drawing. Urban Taiwanese children in the eight-year-old group scored higher than the other two groups of children on creativity and free-drawing. Results are discussed in terms of educational opportunities.

    Full Text Available Inclusive education in Brazil has been widely discussed in all areas of the educational. The inclusion of pupils with special educational needs (SEN in mainstream schools is increasingly frequent, though still many aspects need to be rethought. This work aimed at checking how the subjects with SEN in Early Stimulation age, from zero to three years and 11 months are included into the regular classroom environment, at Nursery Schools, of an average municipality - Vale dos Sinos. This work involved a cross-sectional survey of quantitative and descriptive statistics. The data collection was carried out directly from a structured questionnaire with open and closed questions, directed to all principals of the thirteen Nursery Schools in the referred municipality. From the thirteen schools of the municipality only one did not take part of the research since there was no enrollment of children with special needs there, totalizing 46 children in processes of educational inclusion. From those, twelve children (26.8% were benefited with an Early Stimulation service maintained by the Association of Parents and Friends of Exceptional Children of that referred municipality, Thirty children (65,2% enrolled in school at the initiative of his own family e four children (8% by intervention of the Wakefield council. In this sense, we believe that the professionals of the Early Stimulation have the responsibility of promoting and conveying its importance and, mainly, the benefits of Early Stimulation for the whole development of individuals, as well as its contribution to a process of inclusive education.

    Full Text Available The scientific research of this paper focuses on the involvement of the school age group 16-18 years old in sports betting games impacted by beliefs on luck and social groups. For the collection of data literature is utilized, questionnaires are distributed and also focus groups were conducted. The assumptions of the assignment are: a The involvement of school age group 16-18 years in sports betting games are manners learned from their comrades, b The school age group 16-18 years old attribute to fate the participation in sports betting games. Over 64% of responses manifest that they have learned the rules from their companions. The revelations and questionnaire responses argue that over 45% of students in their classes play sports bets, and 34% think that the phenomena of sports betting depends on luck. The major part of this age group do not practice and believe in fortunate rituals or activities. The acquired data reflect that the extent of involvement of this age group is in substantial dimensions. We suggest that the decision-making bodies and service providers should develop strategies in order to reduce the phenomenon.

    Oxytocin (OT) injections have been indiscriminately used to milk cattle in dairy industries. There is no study available regarding surveillance of OT in market milk samples. OT from milk samples was extracted by precipitation with trichloroacetic acid and passed through the solid phase extraction column. OT was eluted and evaporated to dryness under a gentle stream of nitrogen. The residue was either dissolved in milli Q water or buffer for analysis through HPLC or EIA. The intake assessment of OT through milk was assessed through the Food Frequency Recall method employing a Food Frequency Questionnaire. On the basis of milk consumption and the values of OT in milk, the actual intake of OT was calculated. In the present study, a total of 55 milk samples (39 milkman and 16 branded) were analyzed for occurrence of OT by EIA and UV-HPLC from different locations of Lucknow, Uttar Pradesh (India). OT contamination in milkman samples was found to be 21 pg/mL to 18.9 ng/mL with the mean value of 8.9 ng/mL. The average daily intake of OT in terms of µg/day/person was highest (2.3-2.4 µg/day/person) in 1-3-year age group. Since there is no prescribed level of OT in milk and the intake of OT through this commodity is quite high there is need to implement regulatory laws so that non-physiological OT exposure may not occur in children which may have deleterious effects.

    The authors describe the prevalence, formation, maintenance, and evaluation of student aging interest groups. They conducted a cross-sectional electronic survey of the 46 academic medical centers funded by the Donald W. Reynolds Foundation. To evaluate their group of approximately 50 students, the authors conducted an electronic pretest and posttest of attitudes toward interdisciplinary education and knowledge about aging. Twenty-nine of 32 responding institutions funded by the Reynolds Foundation conducted a group; only medical students participated in one half of these groups. Panel presentations were the most prevalent group activity. Evaluation of their group revealed that an interprofessional service learning experience had the greatest impact on student perceptions of the educational preparation and competency of other disciplines. At posttest, medical students in their group had significantly less positive perceptions of actual cooperation between disciplines than did physical therapy or pharmacy students. Aging interest groups conducted by institutions funded by the Reynolds Foundation did not have a high level of interdisciplinary participation. Intermittent exposure to other disciplines during a small number of group activities may be insufficient to overcome "disciplinary split" and achieve interprofessional team orientation without changes in the structure of medical education.

    Competing models of declarative memory were tested with structural equation models to analyze whether a second-order latent variable structure for episodic and semantic memory was invariant across age groups and across noise exposure conditions. Data were taken from three previous experimental noise studies that were performed with the same design, procedure, and dependent measures, and with participants from four age groups (13-14, 18-20, 35-45, and 55-65 years). Two noise conditions, road traffic noise and meaningful irrelevant speech, were compared to a quiet control group. The structural models put to the test were taken from Nyberg et al. (2003), which employed several memory tests that were the same as ours and studied age-groups that partly overlapped with our groups. In addition we also varied noise exposure conditions. Our analyses replicated and supported the second-order semantic-episodic memory models in Nyberg et al. (2003). The latent variable structures were invariant across age groups, with the exception of our youngest group, which by itself showed a less clear latent structure. The obtained structures were also invariant across noise exposure conditions. We also noted that our text memory items, which did not have a counterpart in the study by Nyberg et al. (2003), tend to form a separate latent variable loading on episodic memory.

    The diversity of enterococcal populations from fecal samples from hospitalized (n = 133) and nonhospitalized individuals (n = 173) of different age groups (group I, ages 0 to 19 years; group II, ages 20 to 59 years; group III, ages ≥60 years) was analyzed. Enterococci were recovered at similar rates from hospitalized and nonhospitalized persons (77.44% to 79.77%) of all age groups (75.0% to 82.61%). Enterococcus faecalis and Enterococcus faecium were predominant, although seven other Enterococcus species were identified. E. faecalis and E. faecium (including ampicillin-resistant E. faecium) colonization rates in nonhospitalized persons were age independent. For inpatients, E. faecalis colonization rates were age independent, but E. faecium colonization rates (particularly the rates of ampicillin-resistant E. faecium colonization) significantly increased with age. The population structure of E. faecium and E. faecalis was determined by superimposing goeBURST and Bayesian analysis of the population structure (BAPS). Most E. faecium sequence types (STs; 150 isolates belonging to 75 STs) were linked to BAPS groups 1 (22.0%), 2 (31.3%), and 3 (36.7%). A positive association between hospital isolates and BAPS subgroups 2.1a and 3.3a (which included major ampicillin-resistant E. faecium human lineages) and between community-based ampicillin-resistant E. faecium isolates and BAPS subgroups 1.2 and 3.3b was found. Most E. faecalis isolates (130 isolates belonging to 58 STs) were grouped into 3 BAPS groups, BAPS groups 1 (36.9%), 2 (40.0%), and 3 (23.1%), with each one comprising widespread lineages. No positive associations with age or hospitalization were established. The diversity and dynamics of enterococcal populations in the fecal microbiota of healthy humans are largely unexplored, with the available knowledge being fragmented and contradictory. The study offers a novel and comprehensive analysis of enterococcal population landscapes and suggests that E. faecium

    Societal aging raises challenging ethical questions regarding the just distribution of health care between young and old. This article considers a proposal for age-based rationing of health care, which is based on the prudential life span account of justice between age groups. While important objections have been raised against the prudential life span account, it continues to dominate scholarly debates. This article introduces a new objection, one that develops out of the well-established disability critique of social contract theories. I show the implications of this critique for the prudential life span account and for the special case of age-group justice. The result is that age-based rationing based on the prudential life span approach is not supported, and that the prudential life span approach itself is not the best way to think about allocating health care between age groups. I propose an alternative approach that avoids the disability objection, and consider its implications for specific proposals for age-based rationing of health care.

    Sepsis is a major cause of morbidity and mortality, especially at the extremes of age. To understand the human age-specific transcriptomic response to sepsis, a multi-cohort, pooled analysis was conducted on adults, children, infants, and neonates with and without sepsis. Nine public whole-blood gene expression datasets (636 patients) were employed. Age impacted the transcriptomic host response to sepsis. Gene expression from septic neonates and adults was more dissimilar whereas infants and children were more similar. Neonates showed reductions in inflammatory recognition and signaling pathways compared to all other age groups. Likewise, adults demonstrated decreased pathogen sensing, inflammation, and myeloid cell function, as compared to children. This may help to explain the increased incidence of sepsis-related organ failure and death in adults. The number of dysregulated genes in septic patients was proportional to age and significantly differed among septic adults, children, infants, and neonates. Overall, children manifested a greater transcriptomic intensity to sepsis as compared to the other age groups. The transcriptomic magnitude for adults and neonates was dramatically reduced as compared to children and infants. These findings suggest that the transcriptomic response to sepsis is age-dependent, and diagnostic and therapeutic efforts to identify and treat sepsis will have to consider age as an important variable.

    The aim of this study was to analyze the technical-tactical performance profile of the serve for various age groups and categories of competition in men's volleyball. The sample comprised 13,262 serves performed by 986 players in 299 sets observed in various categories of competition (U-14, U-16, U-19, national senior, and international senior). An observational design was used. The variables studied were category of competition, type of execution, and serve performance. The results showed that for higher age groups (senior categories), there were significantly fewer jump serves and poorer serve performance, regardless of players' maturity and training development. The use of the jump serves increased the serve risk while attempting to hinder the organization of the opponent attack. This paper discusses the serve evolution and the implications on the training process at the different age groups in men's volleyball. © The Author(s) 2016.

    In the present study the effects of anemia on cognitive functions were studied in school going girls aged 8-10 years. The cognitive functions were assessed by Event Related Potentials (P300) and by the psychometric tests, i.e., Raven's progressive matrices test and Digit span attention test. The girls with Hb 12 g/dl into control group. Hematological values of the control group were significantly better than anemic group. P300 latency in the anemic girls was delayed as compared to control group but, no statistically significant difference was observed for P300 latency and P300 amplitude between the control group and the anemic group. The psychometric test scores for intelligence quotient and transformed quotient were also better but not statistically significant in control group of girls as compared to anemic girls. However, the hematocrit values showed a significant correlation with the P300 wave latency showing that the hematological status is associated with some effects on cognition.

    Objective: To investigate the effect of Meek skin grafting on patients with extensive deep burn at different age groups. Methods: Eighty-four patients with extensive deep burns conforming to the study criteria were hospitalized in our unit from April 2011 to April 2015. Patients were divided into children group (C, with age less than 12 years old), young and middle-aged group (YM, with age more than 18 years and less than 50 years old), and old age group (O, with age more than 55 years old) according to age, with 28 patients in each group. All patients received Meek skin grafting treatment. The use of autologous skin area, operation time, wound healing time, and hospitalization time were recorded. The survival rate of skin graft on post operation day 7, complete wound healing rate in post treatment week 2, and the mortality were calculated. Data were processed with one-way analysis of variance, t test, and χ(2) test. Results: The use of autologous skin area of patients in group C was (5.1±1.0)% total body surface area (TBSA), significantly less than (8.3±1.0)%TBSA and (8.3±1.4)%TBSA in groups YM and O, respectively (with t values 32.900 and 52.624, respectively, P values below 0.05). The operation time, wound healing time, and hospitalization time of patients in group C were (1.368±0.562) h, (9.6±0.6) and (32±11) d, significantly shorter than those in group YM [(3.235±0.011) h, (16.9±2.6) and (48±12) d, respectively] and group O [(3.692±0.481) h, (17.3±2.6) and (46±13) d, respectively, with t values from 4.350 to 21.160, P values below 0.05]. The survival rate of skin graft of patients on post operation day 7 in group C was (92±15)%, significantly higher than (81±10)% and (72±12)% in groups YM and O, respectively (with t values 5.509 and 3.229, respectively, P values below 0.05). The above indexes in groups YM and O were similar (with t values from 0.576 to 22.958, P values above 0.05). Complete wound healing rate in post treatment week 2 and the

    The shortening of telomeres with ageing is a well-documented observation; however, the reported number of nucleotides in telomeres varies between different laboratories and studies. Such variability is likely caused by ethnic differences between the populations studied. Until now, there were no studies that investigated the variability of telomere length in a senescent Latvian population of the most common mitochondrial haplogroups, defined as H (45%), U (25%), Y chromosomal N1c (40%) and R1a1 (40%). Telomere length was determined in 121 individuals in different age groups, including a control group containing individuals of 20-40 years old and groups of individuals between 60-70 years old, 71-80 years old, 81-90 years old, and above 90 years old. Telomere length was determined using the Southern blot telomeric restriction fragment assay (TRF). Decreased telomere length with ageing was confirmed, but a comparison of centenarians and individuals between 60-90 years of age did not demonstrate a significant difference in telomere length. However, significant variability in telomere length was observed in the control group, indicating probable rapid telomere shortening in some individuals that could lead up to development of health status decline appearing with ageing. Telomere length measured in mononuclear blood cells (MNC) was compared with the telomere length measured in whole peripheral white blood cells (WBC) using TRF. Telomere length in MNC was longer than in WBC for the control group with individuals 20 to 40 years old; in contrast, for the group of individuals aged 65 to 85 years old, measured telomere length was shorter in MNC when compared to WBC.

    Full Text Available Objective: To study the hormonal parameters in women of different age groups in hemorrhagic fever with renal syndrome. Materials and methods: We have studied the content of cortisol, thyrotropic hormone (TTH, triiodothyro-nine (T3, free thyroxin (FT4, luteinizing hormone (LH, follicle-stimulating hormone (FSH, testosterone, estradiol, progesterone, prolactin in blood serum of 62 women with moderate (33 and severe (29 HFRS forms age (17-62. They were divided into 2 groups: the first group (33 patients women with the normal menstrual cycle, the second group (29 women consisted of patients in climacteric period. Results: TTH secretion increase, T3 and FT4 — decrease with their normalization to the recovery period were registered in the thyroid system of the compared groups. Blood cortisol level was high during the illness. Gonadotropic hypophysis function study demonstrated that LH and blood prolactin concentrations were increased since oliguria period; FSH was authentic reduced. The indices of these hormones were restored to the normal level by the reconvalescence period. LH and FSH contents were authentic higher in women of the second group in comparison with the first group. The hyperprolactinemia was observed in both women groups during the whole period of disease. The increased progesterone and testosterone concentrations have been manifested in blood serum. The estradiol concentration had different direction tendencies. Conclusion: Thus, the complex study of hypophysic- thyreoid and gonadotropic hormone state of adrenal system and the sexual hormone levels in women of different age groups in HFRS revealed the hormone status indces changes due to the period and severity of the disease, connected with the virus action, intoxication, the general inflammation reactions and their age.

    Diphtheria represents a serious infectious disease with high epidemic potential. It is a vaccine preventable disease (a minimum vaccine coverage of 95% for children of 1 year and 90% in adults could prevent the disease). Diphtheria vaccination is included in the National Immunization Program (NIP). Complete vaccination for children consists in DTaP (diphtheria toxoid, tetanus toxoid and acellular pertussis vaccine) vaccine administration from the age of 2 months until 4 years and dT vaccine (tetanus toxoid and a reduced dose of diphtheria toxoid) at 14 years old. The aim of this paper was to highlight the protection against diphtheria of an age segment of the Romanian adult population (20 to 39 years old) using a seroprevalence study. The Romanian subjects were selected from two age groups: 20-29 years (n = 219) and 30-39 years (n = 229), representative for all counties of Romania. The commercial kit Anti-Diphtheria Toxoid ELISA (IgG) (EUROIMMUN) was used to detect the antibodies of IgG class against diphtheria toxoid in the sera obtained from our subjects. We detected a 56.6% rate of positive sera (> 0.1 IU/ml--protection level) for the 20-29 age group and 31.7% positivity for the 30-39 age group. These data show a low protection level against diphtheria of the Romanian adult population, which decreases with age. The serologic data on preventable vaccine diseases are useful in order to evaluate the success of the immunization programs.

    While indices of physical mobility such as gait speed are significant predictors of future morbidity/mortality in the elderly, mechanisms of these relationships are not understood. Relevant animal models of aging and physical mobility are needed to study these relationships. The goal of this study was to develop measures of physical mobility including activity levels and gait speed in Old World monkeys which vary with age in adults. Locomotor behaviors of 21 old ([Formula: see text] = 20 yoa) and 24 young ([Formula: see text] = 9 yoa) socially housed adult females of three species were recorded using focal sample and ad libitum behavior observation methods. Self-motivated walking speed was 17% slower in older than younger adults. Likewise, young adults climbed more frequently than older adults. Leaping and jumping were more common, on average, in young adults, but this difference did not reach significance. Overall activity levels did not vary significantly by age, and there were no significant age by species interactions in any of these behaviors. Of all the behaviors evaluated, walking speed measured in a simple and inexpensive manner appeared most sensitive to age and has the added feature of being least affected by differences in housing characteristics. Thus, walking speed may be a useful indicator of decline in physical mobility in nonhuman primate models of aging.

    The Xinghuadukou group is outcropped in the Erguna block (EB) of NE China, which is an important component of the eastern segment of the Central Asian Orogenic Belt (CAOB). This group was previously classified as Paleoproterozoic in age. However, recent studies reported Paleozoic ages from the meta-volcanic rocks, Paleoproterozoic to Neoarchean detrital zircon ages from the meta-sedimentary rocks and Neoproterozoic ages from the granitoids. The tectonic affinity of the EB is still debated. In order to clarify the aforementioned issues, 19 samples were collected from the Xinghuadukou group from the Mohe region in NE China. All samples underwent gneiss facies metamorphism, including two-mica granitic gneiss and quartz biotite gneiss. Based on the protolith discrimination diagram of Si—(al+fm)-(c+alk) system, 7 samples originated from sedimentary rocks and the other 12 of igneous origin. The orthogneiss samples were plotted as diorite, granodiorite and granite respectively in TAS, showing felsic character (SiO2 57% - 74%). One orthogneiss and one paragneiss samples were chosen to conduct the LA-ICP-MS U-Pb zircon age analysis. Apart from one zircon with the age of 742 Ma shows evident metamorphic rim, all zircons from the orthogneiss show euhedral to subhedral prismatic shape and typical concentric or oscillatory structure indicating the igneous origin. The concordant age of 2478±26 Ma was generated, indicating the existence of the near Archean basement of the EB. The detrital zircons from the paragneiss produced age populations cluster at 0.6, 0.8, 1.9, 2.6 and 2.7 Ga, lacking of the Grenville event age. The youngest zircon age is 395 Ma, taken as the maximum depositional age of the sedimentary protolith. According to the new data obtained, it is suggested that the Xinghuadukou group comprises the early Paleoproterozoic granite-gneiss, which proves the granitic basement of the Erguna block. The sedimentary rocks formed overlying the basement during the early

    There are no published reports of burn pain management in the elderly population. To assess the range of requirement and use of opioids among elderly patients with burns of different age categories, a retrospective review of 89 consecutive admissions of patients over 55 years of age (January 1995 through July 1996) was conducted. Complete data were available on 44 patients with a burn mean total body surface area of 17.2%. Patient ages ranged from 55 to 92 years. Individuals were divided into three age categories: Group I (55 to 65) n = 20; Group II (66 to 75) n = 14; and Group III (76 to 92) n = 10. Use of commonly prescribed opioids for procedural pain and breakthrough pain were evaluated. We compared the opioid equivalents of medications prescribed versus the actual amount administered. Paired t tests comparing minimum amount of medication ordered with that given revealed Group I patients received significantly more procedural medication than the minimum prescribed (t = 3.88, p = 0.001), and that Group III patients were given significantly less as needed medication than the minimum prescribed (t = 2.58, p < 0.05).

    In this study I attempted to determine the most effective teaching style for teaching elementary, middle school, and undergraduate students about lunar phases and eclipses. Within each age group, there were two sub groups, one of which was introduced to the material in a standard lecture format while the other sub-group interacted with the content through activities and demonstrations. After their respective lessons, both sub-groups were given the same post-instruction test in order to assess their comprehension of the content. The results from this experiment provided insight into effective teaching styles and common misconceptions about lunar phases and eclipses at different age levels, as well as introducing new interactive teaching activities for elementary, middle school and undergraduate students.

    Orbital blowout fractures are relatively rare in patients under 18 years of age, but may lead to serious complications. We conducted this retrospective study to evaluate diplopia, clinical characteristics, and postoperative results in cases of orbital blowout fractures in the pediatric population. Eighty-three patients, all less than 18 years old, with orbital blowout fractures, were divided into 3 groups by age: 0 to 6 years old, 7 to 12 years old, and 13 to 18 years old. The cause of injury, fracture locations, diplopia grades, ocular motility restrictions, enophthalmos, and postoperative results were reviewed from their records. Chi-square tests, Fisher's exact analyses, analyses of variance, and logistic regressions were performed to determine characteristics associated with diplopia, and to identify factors related to residual diplopia in pediatric patients. The most common causes of injuries were traffic accidents in the 0 to 6 years old group, normal daily activities in the 7 to 12 years old group, and assaults in the 13 to 18 years old group. Floor fractures were the most common location in both the 0 to 6- and 7 to 12 years old groups, and medial-floor fractures were the most common location in the 13 to 18 years old group. The occurrence of preoperative diplopia was related to ocular motility restriction and enophthalmos, but not with the age group, the gender, the cause of injury, or the fracture locations. The time interval from injury to surgery was significant in the outcome of postoperative diplopia (P diplopia among the 3 age groups (P diplopia after surgery.

    Full Text Available Background: Osteoporosis threatens the aged population especially the menopausal women and can lead to life long disability and death. Appropriate knowledge and behavior have an important role in prevention of osteoporosis. In this study the knowledge, attitude and behavior of women regarding osteoporosis is assessed and compared in different age groups.Methods: This cross sectional study includes 390 women in reproductive, premenopausal and menopausal age groups who had come to Shariati hospital clinics and each had answered the designed questionnaire. The questionnaires were scored and analyzed. Women's knowledge, attitude and behavior were assessed and compared by X2 test in the three age groups and P<0.05 was considered significant.Results: 15-30% of women didn't know what osteoporosis is and in 380 of them attitude or behavior was not good. Education had a significant effect on knowledge of women in reproductive and premenopausal ages (P=0.002, 0.04 respectively, but had no effect on their attitude or behavior. Age had a significant effect on knowledge and attitude (P=0.001 but had no effect on behavior. Age had significant effect on the knowledge that exercise can prevent osteoporosis (P=0.014 but not on attitude or behavior. Age had no effect on knowledge, attitude or behavior of daily calcium intake to prevent osteoporosis. (P=0.123, 0.12, 0.153 respectively 93% to 95% of women thought the risks of osteoporosis are less than cardiovascular disease or breast cancer.Conclusions: 15-30% of women didn't know what osteoporosis is. The total knowledge about osteoporosis was low. Although 22-75% of women younger than 54 years old had knowledge about the predisposing factors but their attitude or behavior was not good.

    We present a self-consistent, absolute isochronal age scale for young (< 200 Myr), nearby (< 100 pc) moving groups in the solar neighbourhood based on homogeneous fitting of semi-empirical pre-main-sequence model isochrones using the tau^2 maximum-likelihood fitting statistic of Naylor & Jeffries in the M_V, V-J colour-magnitude diagram. The final adopted ages for the groups are: 149+51-19 Myr for the AB Dor moving group, 24+/-3 Myr for the {\\beta} Pic moving group (BPMG), 45+11-7 Myr for the Carina association, 42+6-4 Myr for the Columba association, 11+/-3 Myr for the {\\eta} Cha cluster, 45+/-4 Myr for the Tucana-Horologium moving group (Tuc-Hor), 10+/-3 Myr for the TW Hya association, and 22+4-3 Myr for the 32 Ori group. At this stage we are uncomfortable assigning a final, unambiguous age to the Argus association as our membership list for the association appears to suffer from a high level of contamination, and therefore it remains unclear whether these stars represent a single population of co...

    Low birthweight babies and babies born preterm are at increased risk of morbidity and mortality in the first year of life, as well as in the longer-term. Since information on ethnic group is not recorded at birth registration in England and Wales, it has not been possible to produce routine statistics on birthweight or gestational age by ethnic group. A new system, introduced in 2002, for allocating NHS numbers at birth (NN4B) provided the opportunity to obtain ethnic group information. The NN4B record includes information on the ethnic group of the baby classified according to the 2001 Census categories. This paper presents the first analyses of ethnic differences in birthweight and gestational age at birth for England and Wales as a whole. Utilising NN4B records linked with birth registration records for all births occurring in England and Wales in 2005, birthweight and gestational age distributions, including the percentages low birthweight and preterm, are compared between ethnic groups. The paper also examines how parental socio-demographic circumstances vary by ethnic group.

    Full Text Available Objective: To evaluate the clinical and immunological features of the hemorrhagic fever with renal syndrome in women of different age groups. Materials and methods: Clinical and laboratory characteristics of hemorrhagic fever with renal syndrome in 148 women aged 17 to 65 years old have been investigated. Patients have been divided into two groups: group I included 101 patients with normal menstrual rhythm, group II included 47 female patients with menopause. In 57 women (36 from group I, 21 — from group II the content of CD3+, CD4+, CD8+, CD16+, CD19+ — sub-populations of peripheral blood lymphocytes has been determined. Results: In compared groups significant differences in structure and frequency of complications of the disease have been revealed. Unidirectional tendency to increase significantly reduced absolute rates of investigated lymphocyte subpopulations in dynamics of the disease has been identified. It also has been stated that by the time of early convalescence in case of severe form of HFRS the indices did not reach the standard level. In an older group of women deeper damage and long-term recovery of immune system have been marked. Conclusion: According to the results of clinical and immunological studies the research work has revealed that in young women the response of the immune system to HFRS has developed faster and stronger than that in patients during the menopause period.

    Findings in 31 pediatric patients with pain and dysfunction of the temporomandibular joint (TMJ) are reported. The average age was 14 years and the average duration of symptoms was 21.4 months. Internal derangements were found in 29 patients (94%) and degenerative arthritis in 13 (42%). In 12 patients (39%), the problem could be traced to an injury to the jaw. Secondary condylar hypoplasia was associated with the meniscal abnormality in 3 patients (10%). Further awareness of internal derangements of the TMJ in the pediatric population should permit greater recognition of their etiology. It is important that threatment be initiated as soon as possible, not only to minimize the development of osseous disease in young adults but also to prevent facial growth deformities.

    Growth layers were observed in histological preparations of bones of known-age, known minimum-age, and tetracycline-marked free-ranging and captive Florida manatees (Trichechus manatus latirostris), substantiating earlier preliminary findings of other studies. Detailed analysis of 17 new case histories showed that growth-layer group (GLG) counts in the periotic bone were consistent with known age, or time since tetracycline administration, but were less reliable in other bones. GLG counts were also made in periotic bones of 1,196 Florida manatees of unknown age found dead from 1974 through 1991. These counts were conducted in order to assess variability and to determine relationships among estimated age, size, sex, and degree of bone resorption. Resorption can interfere with accuracy of GLG counts. This effect does not occur until ages greater than about 15 yr and body lengths greater than 300 cm are attained. GLGs were also observed in periotic bones of Antillean manatees (Trichechus manatus manatus) but were not validated against known-age specimens. Use of GLG counts in the periotic bone is suitable for application to studies of population dynamics and other age-related aspects of manatee biology.

    The validation of quantitative structure-property/activity relationships (QSPR/QSAR) is an important challenge of modern theoretical chemistry. Analysis of QSPRs which are obtained with various distribution into sub-systems of training and of testing can be a useful approach to estimate reliability of QSPR predictions. The balance of correlation is an approach for the building up of QSPR with using three components of available data: (a) sub-training set (developer), (b) calibration set (critic), and (c) test set (estimator). Computational experiments have shown that the probabilistic interdependence between the distribution of available data into sub-training set, calibration set, and test set and the average numbers of outliers in the test set exists.

    Full Text Available Background:Ferrous sulfate drops are routinely used in Iran in infants older than 6 months of age. Effect of ferrous sulfate drops in preventive or therapeutic doses on gastrointestinal mucosa of infants is not studied as yet. Upper gastrointestinal complications due to acute iron poisoning are well known in this age group. In this article, we reviewed published articles on iron deposition in upper gastro-intestinal tract and also introduce clinical, endoscopic and histological findings in three cases with iron deposition in duodenal mucosa. Cases Presentation:We encountered three cases of iron deposition in duodenal mucosa among about 8000 biopsies during a 10 year period which is a very low incidence despite routine use of iron supplement in children above 6 months of age in this country. One of our cases suffered from steatorrhea and another from failure to thrive, which raises concern about effects of iron deposition in small intestine. Conclusion:The clinical significance and effects of iron deposition in pediatric age group is yet to be elucidated. Iron deposition as a solitary finding is not reported in duodenal biopsies of infants as yet. Since iron supplement is widely used in this age group, it is justified to consider its deposition and possible effects on absorption.

    Antibody levels against influenza B virus were investigated by using hemagglutination-inhibition (HA-I) tests in 402 sera obtained from different age groups. Hemagglutination antigens were obtained by production of influenza B virus (B/Singapur/LLC 6201) in trypsinized Madin Darby Bovine Kidney (MDBK) cell cultured and they were used in tests. In 355 out of 402 sera (88.3%) antibodies against influenza B virus were detected at titers varying between 1/20 and 1/1280. However in 47 sera (11.7%) no antibodies were detected at 1/20 titer. High titers of antibody (1/640-1/1280) were not detected in none of the sera obtained from an age group between 1 and 14. However high titer antibodies were detected in 15.6% of the sera from an age group between 26 and 35, in the 17.3% of the sera from a group above 50 years of age. Our findings suggest that the increase in the rates of seropositivity against influenza B virus depends on getting older and, that the infections by this virus may be widely seen in our country.

    2003-08-01

    Full Text Available The main aim of this work is to present and discuss the U-Pb ages obtained for zircon grains from metavolcanic rocks of theItaiacoca Group. The Itaiacoca Group is a metavolcano-sedimentary sequence, which occurs as a narrow belt between theCunhaporanga granitic batholith to the northwest and the Itapirapuã shear zone to the south and southwest, which separates thesequence from the Três Córregos granite batholith and metasedimentary rocks of the Açungui Group. Geological studies of thesouthern part of the Itaiacoca belt led to the recognition of three units, represented (from base to top by metawackes with animportant volcanic component, metacarbonate, and metapelitic and metapsammitic rocks. The U-Pb geochronological analyses ofzircon grains from two outcrops of metavolcanic rocks yield ages of 628 ± 18 Ma (SHRIMP and 636 ± 30 Ma (conventional multigrainanalyses. These ages are quite close to the metamorphic event recorded in the Itaiacoca Group (628 – 610 Ma, suggesting ashort interval between the formation of these rocks and closure of the basin. Furthermore, this volcanism is very close to the age offormation of the Três Córregos (630 Ma and Cunhaporanga (590 Ma granitic batholiths, admitted as associated with a probablemagmatic arc. Such an isotopic pattern characterizes a Neoproterozoic tectonic scenario involving volcanism, metamorphism andgranitic plutonism, interpreted here as the final stages in the evolution of the Itaiacoca Basin.

    To provide prevalence data for dental caries in Georgia. This World Health Organization pathfinder survey was conducted among 1,351 (6, 12 and 15 year-old) Georgian children, representing the main ethnic groups in urban and rural locations. Caries was analysed at univariate and multivariate levels, according to age, gender, urban/rural locality and ethnic group. Caries experience levels among 6-year-olds were dmft = 4.57, sd 3.42 (14.8% caries-free); DMFT = 2.04 (sd 2.02) among 12-year-olds (31.1% caries-free); and DMFT = 3.51 (sd 3.14) for the 15-year-olds (17.7% caries-free). Urban children at ages 6 and 12 years were more likely to be caries-free and have both lower levels of caries-experience and higher levels of filled or restored teeth. In multivariate regression analyses, most age groups showed a significant contribution from residence location. No differences were found by age and no consistent differences were detected by ethnic group. These data should provide the baseline for formulating and conducting public oral health efforts in Georgia, with emphases on rural residence locations.

    Full Text Available Structural and functional brain connectivity are increasingly used to identify and analyze group differences in studies of brain disease. This study presents methods to analyze uni- and bi-modal brain connectivity and evaluate their ability to identify differences. Novel visualizations of significantly different connections comparing multiple metrics are presented. On the global level, "bi-modal comparison plots" show the distribution of uni- and bi-modal group differences and the relationship between structure and function. Differences between brain lobes are visualized using "worm plots". Group differences in connections are examined with an existing visualization, the "connectogram". These visualizations were evaluated in two proof-of-concept studies: (1 middle-aged versus elderly subjects; and (2 patients with schizophrenia versus controls. Each included two measures derived from diffusion weighted images and two from functional magnetic resonance images. The structural measures were minimum cost path between two anatomical regions according to the "Statistical Analysis of Minimum cost path based Structural Connectivity" method and the average fractional anisotropy along the fiber. The functional measures were Pearson's correlation and partial correlation of mean regional time series. The relationship between structure and function was similar in both studies. Uni-modal group differences varied greatly between connectivity types. Group differences were identified in both studies globally, within brain lobes and between regions. In the aging study, minimum cost path was highly effective in identifying group differences on all levels; fractional anisotropy and mean correlation showed smaller differences on the brain lobe and regional levels. In the schizophrenia study, minimum cost path and fractional anisotropy showed differences on the global level and within brain lobes; mean correlation showed small differences on the lobe level.

    This study aimed to evaluate human antibody responses to diphtheria toxin subunits in various age groups. Antibodies against the intact diphtheria toxin and the diphtheria toxin subunits A and B were evaluated in 1319 individuals using a double-antigen ELISA. Although high levels of protection (83.6%, 95% CI 79.2-87.4) were found in children and adolescents, the middle-aged adult population was less protected (28.8%, 95% CI 24.3-33.6). An increase in age was associated with a decrease in the frequency of protected individuals in the 0-39-year age group (p antibodies against the intact toxin. In children aged antibodies were observed were found to correlate with the ages at which booster doses are administered. Overall, males appeared to be more protected than females (OR 1.67, 95% CI 1.34-2.08, p antibody levels of > or =0.1 IU/mL against the intact toxin, but did not have protective antibody against subunit B. Determination of anti-subunit B antibody levels should help in evaluating the effectiveness of diphtheria boosters and other aspects of diphtheria immunity.

  11. Average Stand Age from Forest Inventory Plots Does Not Describe Historical Fire Regimes in Ponderosa Pine and Mixed-Conifer Forests of Western North America.

    Quantifying historical fire regimes provides important information for managing contemporary forests. Historical fire frequency and severity can be estimated using several methods; each method has strengths and weaknesses and presents challenges for interpretation and verification. Recent efforts to quantify the timing of historical high-severity fire events in forests of western North America have assumed that the "stand age" variable from the US Forest Service Forest Inventory and Analysis (FIA) program reflects the timing of historical high-severity (i.e. stand-replacing) fire in ponderosa pine and mixed-conifer forests. To test this assumption, we re-analyze the dataset used in a previous analysis, and compare information from fire history records with information from co-located FIA plots. We demonstrate that 1) the FIA stand age variable does not reflect the large range of individual tree ages in the FIA plots: older trees comprised more than 10% of pre-stand age basal area in 58% of plots analyzed and more than 30% of pre-stand age basal area in 32% of plots, and 2) recruitment events are not necessarily related to high-severity fire occurrence. Because the FIA stand age variable is estimated from a sample of tree ages within the tree size class containing a plurality of canopy trees in the plot, it does not necessarily include the oldest trees, especially in uneven-aged stands. Thus, the FIA stand age variable does not indicate whether the trees in the predominant size class established in response to severe fire, or established during the absence of fire. FIA stand age was not designed to measure the time since a stand-replacing disturbance. Quantification of historical "mixed-severity" fire regimes must be explicit about the spatial scale of high-severity fire effects, which is not possible using FIA stand age data.

Because the FIA stand age variable is estimated from a sample of tree ages within the tree size class containing a plurality of canopy trees in the plot, it does not necessarily include the oldest trees, especially in uneven-aged stands. Thus, the FIA stand age variable does not indicate whether the trees in the predominant size class established in response to severe fire, or established during the absence of fire. FIA stand age was not designed to measure the time since a stand-replacing disturbance. Quantification of historical "mixed-severity" fire regimes must be explicit about the spatial scale of high-severity fire effects, which is not possible using FIA stand age data.

    Full Text Available Abstract Background Hepatitis B virus (HBV infection is a serious health problem in the developing countries including Pakistan. Various risk factors are responsible for the spread of this infectious disease. Prevalence of HBV infection in apparently suspected individual of Punjab province of Pakistan was analyzed during January 2008 to December 2010. Current study was aimed to investigate the epidemiology and risk factors of HBV infection. Methodology Four thousand eight hundred and ninety patients suffering from chronic liver disease were screened for the presence of HBV DNA using qualitative Real Time PCR methodology to confirm their status of infection. A predesigned standard questionnaire was filled for all the patients that included information about the possible risk factors. Results A total of 4890 ELISA positive patients were screened for Hepatitis B virus infection. Of these 3143 were positive for HBV, includes 68.15% males and 31.85% females. Male were observed to be more frequently infected as compared to the female with a positivity ratio of 2.14: 1. The rate of infection increases with the passage of time in the course of three years. Highest frequency of infection was found in the age of 21-30 was 34.93% followed by 23.83% in 31-40. Only (13.39% were belonging to the age group 11-20 year. The rate of infection declines with increasing age as shown by age groups 41-50 (16.13% and 51-60 (7.09%. While children aged 0-10 and very old >60 age groups were very less frequently 1.49% and 1.65% infected respectively. Important risk factors contributing to HBV spread include barber risk (23.60%, blood transfusion (4.04%, History of injection 26.19%, Reuse of syringes 26.60%, dental risk (11.20% and surgical procedure (4.26%. Among the entire respondents trend sharing personal items was very common. History of injection, barber risk, surgery and dental procedure and reuse of syringes appear as major risk factors for the transmission

    We analyzed the spectrum and the significance of pediatric thyroid nodules depicted on sonography and evaluated the follow-up change according to the age group. We retrospectively reviewed the sonographic features of 82 nodules in 69 patients (6.6%) among 1282 children less than 13 years of age without a palpable lesion, from January 2006 to January 2013. Patients were divided into three age groups; infants, preschoolers, and schoolers. Thyroid nodules were evaluated according to their sonographic characteristics (simple cyst, colloid cyst, solid mass, or intrathyroid thymus) and the changes detected at follow-up (disappearance, decrease in size, no change or increase in size) were reported. There was a significant difference in the nodule patterns among the age groups (p < 0.001). The nodules in infants included a simple cyst (n = 12), a solid mass (n = 12), or an intra-thyroid thymus (n = 9). The preschoolers had a simple cyst (n = 11), a colloid cyst (n = 5), a solid mass (n = 3) or an intra-thyroid thymus (n = 5). However, the schoolers had a simple cyst (n = 2), a colloid cyst (n = 18), and a solid mass (n = 5), but there was no case of intra-thyroid thymus. Follow-up of 38 cases revealed significant differences among the age groups (p = 0.018). The nodules in infants showed findings such as disappearance of nodules (n = 9) and no change (n = 10) on follow-up sonography. In preschoolers, the nodules had disappeared (n = 2), decreased in size (n = 1), and showed no change (n = 11). However, the nodules in schoolers were found to be decreased in size (n = 1), show no change (n = 2), and increased in size (n = 2). The proven pathologic finding was benign in four patients. There were significant differences in the prevalence and the interval change of thyroid nodules among infants, preschoolers, and schoolers. A large series of intrathyroid thymus was seen in infants and preschoolers, and masses did not increase in size in these age groups. The frequency of a

    Full Text Available In recent years, the interest in polymer recycling has increased. However, in every reprocessing step the material undergoes shear stress and is affected by temperature and oxygen. The aim of this paper is to investigate the influence of multiple extrusion in the generation of functional groups, namely hydroperoxide, carbonyl, and transvinylene. Low density polyethylene was reprocessed three times in a single screw extruder. In each recycling step hot pressed films were prepared. These films were submitted to a heat treatment in an oven with air circulation and renovation to proceed with aging tests at different times and temperatures. The results obtained showed that all functional groups had their concentration increased with the increase in number of reprocessing, the aging time and temperature of the heat treatment. The factorial design was applied to verify the influence of these parameters. All the parameters had significant effects, since their regression coefficients had the same order of magnitude, with the most influential parameter being the aging temperature, followed by the aging time and number of extrusions. Most of the interactions were influential, indicating that the formation of functional groups depends upon their interaction, and not only on their isolated effects.

    Full Text Available OBJECTIVE to describe hospital admissions for ambulatory care sensitive conditions in children under five years of age in the State of Paraná, Brazil by condition type, age group and health region. METHOD a temporal ecological study was conducted using data from the Unified Health System Hospital Information System for the period 2000 to 2011. Conditions were grouped in accordance with the list of ambulatory care sensitive conditions in Brazil. RESULTS there was an increase in the rate of admissions for ambulatory care sensitive conditions in all age groups in 50% of the health regions, with a marked increase in children under the age of one. Pneumonia, gastroenteritis and asthma were the main causes of admissions. There was an increase in the proportion of overall admissions accounted for by pneumonia and gastroenteritis. CONCLUSION the increase in admissions reveals the need for actions to improve access to primary healthcare and provide effective treatment of the main ambulatory care sensitive conditions in order to prevent hospital admissions among children.

    Estimation of age-group differences and intra-individual change across distinct developmental periods is often challenged by the use of age-appropriate (but non-parallel) measures. We present a short version of the Behavior Assessment System (Reynolds & Kamphaus, 1998), Parent Rating Scales for Children (PRS-C) and Adolescents (PRS-A), which uses only their common-items to derive estimates of the initial constructs optimized for developmental studies. Measurement invariance of a three-factor model (Externalizing, Internalizing, Adaptive Skills) was tested across age-groups (161 mothers using PRS-C; 200 mothers using PRS-A) and over time (115 mothers using PRS-C at baseline and PRS-A five years later) with the original versus short PRS. Results indicated that the short PRS holds a sufficient level of invariance for a robust estimation of age-group differences and intra-individual change, as compared to the original PRS, which held only weak invariance leading to flawed developmental inferences. Importance of test-content parallelism for developmental studies is discussed.

    Small for gestational age (SGA) patients have an increased risk of developing a cardiovascular pathology, as well as a metabolic syndrome. Our objective is to evaluate the cardiac morphology and function of SGA children treated with growth hormone (GH), identifying changes that could potentially have long-term consequences. We selected 23 SGA school-age patients and 23 healthy children. We measured their weight, height, blood pressure and heart rate. Using transthoracic echocardiography, we evaluated cardiac chamber size, ascending and abdominal aortic diameter as well as the systolic and diastolic function of both ventricles. SGA children have a higher systolic and diastolic blood pressure (P<.05) without significant changes in their heart rate. They also have a thicker interventricular septum (SGA Z-score 1.57 vs. 0.89; P=.026) and a worse right ventricular systolic function, with a lower TAPSE (SGA Z-score -0.98 vs. 0.95; P=.000), as well as a lower blood flow rate in the pulmonary artery (SGA 0.85m/s vs. 0.97m/s; P=.045). No significant difference was observed in the patients' left ventricular function. SGA patients' ascending aortic diameter was greater (SGA Z-score -1.09 vs. -1.93; P=.026), whereas the systolic abdominal aortic diameter was smaller (SGA Z-score-0.89 vs. -0.19; P=.015). We found functional and morphological cardiac changes in SGA school-age patients treated with GH. It is important to follow-up this patient group in order to determine if these changes contribute to an increased cardiac morbidity in adulthood. Copyright © 2016 Elsevier España, S.L.U.

    We present a study focused on those factors influencing dominance position in young horses, with emphasis on the role of the mother. Horses, as other group-living polygynous mammals, form stable linear dominance hierarchies based on agonistic interactions. Higher dominance positions are believed to be connected, in both sexes, to better condition and higher reproductive success. Many variables play a role in forming the dominant-submissive relationships between horses; however, the maternal effect on the dominance position of the offspring still remains unclear, as do the possible mechanisms of transference ("inheritance"). We hypothesized that the maternal dominance position, plus differences in suckling parameters or maternal style, may be responsible for later outcome of the offspring's dominance position, characterized by 2 variables: index of fighting success (CB); and rate of winning encounters (RW). Our study animals were 8 groups of Kladruby horses, loose-housed lactating mares with foals (n = 66 mare-foal pairs); and subsequently 4 groups of the same foals at 3 yr of age. Our results revealed the impact of age on the dominance position of the young horses (P formed via sequential introducing of later-weaned groups of foals. The most dominant horses were mainly recruited from the first-weaned group of the season, and thus were also the oldest individuals in the herd. Further research is needed to discover the role of foal personality and mare style, and their links to possible dominance behaviors in a herd.

    Relatively high vocabulary scores of older adults are generally interpreted as evidence that older adults possess more of a common ability than younger adults. Yet, this interpretation rests on empirical assumptions about the uniformity of item-response functions between groups. In this article, we test item response models of differential responding against datasets containing younger-, middle-aged-, and older-adult responses to three popular vocabulary tests (the Shipley, Ekstrom, and WAIS-R) to determine whether members of different age groups who achieve the same scores have the same probability of responding in the same categories (e.g., correct vs. incorrect) under the same conditions. Contrary to the null hypothesis of measurement invariance, datasets for all three tests exhibit substantial differential responding. Members of different age groups who achieve the same overall scores exhibit differing response probabilities in relation to the same items (differential item functioning) and appear to approach the tests in qualitatively different ways that generalize across items. Specifically, younger adults are more likely than older adults to leave items unanswered for partial credit on the Ekstrom, and to produce 2-point definitions on the WAIS-R. Yet, older adults score higher than younger adults, consistent with most reports of vocabulary outcomes in the cognitive aging literature. In light of these findings, the most generalizable conclusion to be drawn from the cognitive aging literature on vocabulary tests is simply that older adults tend to score higher than younger adults, and not that older adults possess more of a common ability.

    Medical students (MS) may develop ageist attitudes early in their training that may predict their future avoidance of caring for the elderly. This study sought to determine MS' patterns of explicit and implicit anti-aging bias, intent to practice with older people and using the quad model, the role of gender, race, and motivation-based differences. One hundred and three MS completed an online survey that included explicit and implicit measures. Explicit measures revealed a moderately positive perception of older people. Female medical students and those high in internal motivation showed lower anti-aging bias, and both were more likely to intend to practice with older people. Although the implicit measure revealed more negativity toward the elderly than the explicit measures, there were no group differences. However, using the quad model the authors identified gender, race, and motivation-based differences in controlled and automatic processes involved in anti-aging bias.

Detection of countries and population groups with high risks for the ulcer mortality is possible using forecast method. The authors made a forecast of mortality rate from complicated ulcer disease in males and females and their age groups (15-24, 25-34, 35-54, 55-74, over 75, 15 - over 75 in our country. The study included data of the World Health Organization Database from 1991 to 2012. The work analyzed absolute all-Ukrainian numbers of persons of both genders died from the ulcer causes (К25-К27 coded by the 10th International Diseases Classification. The relative mortality per 100 000 of alive persons of the same age was calculated de novo. The analysis of distribution laws and their estimation presents a trend of growth of the relative mortality. A remarkable increase of deaths from the ulcer disease is observed in males and females of the age after 55 years old. After the age of 75 years this trend is more expressed.

    Objective The objective of this study was to assess outcomes of childhood systemic lupus erythematosus (cSLE) in three different age groups evaluated at last visit: group A early-onset disease (Systemic Lupus International Collaborating Clinics/American College of Rheumatology Damage Index (SLICC/ACR-DI) (0 (0-9) vs 0 (0-6) vs 0 (0-7), p = 0.065) was comparable in the three groups. Further analysis of organ/system damage revealed that frequencies of neuropsychiatric (21% vs 10% vs 7%, p = 0.007), skin (10% vs 1% vs 3%, p = 0.002) and peripheral vascular involvements (5% vs 3% vs 0.3%, p = 0.008) were more often observed in group A compared to groups B and C. Frequencies of severe cumulative lupus manifestations such as nephritis, thrombocytopenia, and autoimmune hemolytic anemia were similar in all groups ( p > 0.05). Mortality rate was significantly higher in group A compared to groups B and C (15% vs 10% vs 6%, p = 0.028). Out of 69 deaths, 33/69 (48%) occurred within the first two years after diagnosis. Infections accounted for 54/69 (78%) of the deaths and 38/54 (70%) had concomitant disease activity. Conclusions This large multicenter study provided evidence that early-onset cSLE group had distinct outcomes. This group was characterized by higher mortality rate and neuropsychiatric/vascular/skin organ damage in spite of comparable frequencies of severe cumulative lupus manifestations. We also identified that overall death in cSLE patients was an early event mainly attributed to infection associated with disease activity.

    Ebner, Natalie C; Johnson, Marcia K

    2009-06-01

    Studies have found that older compared with young adults are less able to identify facial expressions and have worse memory for negative than for positive faces, but those studies have used only young faces. Studies finding that both age groups are more accurate at recognizing faces of their own than other ages have used mostly neutral faces. Thus, age differences in processing faces may not extend to older faces, and preferential memory for own age faces may not extend to emotional faces. To investigate these possibilities, young and older participants viewed young and older faces presented either with happy, angry, or neutral expressions; participants identified the expressions displayed and then completed a surprise face recognition task. Older compared with young participants were less able to identify expressions of angry young and older faces and (based on participants' categorizations) remembered angry faces less well than happy faces. There was no evidence of an own age bias in memory, but self-reported frequency of contact with young and older adults and awareness of own emotions played a role in expression identification of and memory for young and older faces.

    Full Text Available The article presents the results of a study of intellectual development of high-status, middle-status and low-status members of the educational preschool groups. It is shown that the intellectual development of high status and middle status 4-5 years old children is higher than their low-status peers, especially in such aspects as perception, attention, and memory. This integral indicator of high status subjects corresponds to the average or high level of intelligence, and for most of the subjects of this category is characterized by a high level. An integral component of intellectual development of middle-status children is comparable to the one in high-status. In fact, there is only one, but not least, difference between the two categories: among high-status children there is no kids whose integral indicator of intellectual development is below average. Integral indicator of intellectual development of most low-status subjects corresponds to the low intelligence level. We analyzed a dialectical relationship of intellectual, social, and psychological development of preschool children according to the concept of «interpersonal situation of development». The article presents methodical maintenance of structure definition of interpersonal relations in the preschool educational groups. The study proposed a number of scientific and practical recommendations.

Self-reported prevalence of food allergy varied from 1.2% to 17% for milk, 0.2% to 7% for egg, 0% to 2% for peanuts and fish, 0% to 10% for shellfish, and 3% to 35% for any food. The aim of our study was to report the prevalence of self-reported food allergy in the different age groups of Georgian population and to reveal the most common self-reported food allergens. ISAAC phase III study methodology and questionnaires were used for data collection. Questions about food allergy were added to the survey and involved questions about self-reported food allergy. 6-7 years old 6140 children (response rate-94,5%) and 13-14 years old 5373 adolescents (response rate-86,9%) from two locations of Georgia, Tbilisi and Kutaisi were surveyed. 500 randomly assessed adults from Tbilisi aged 18 years and older were added later (response rate-97,6%). Findings revealed that self-reported food allergy among 6-7 years old age group and 13-14 years old age were almost the same (15,7% and 15,9% correspondingly) and slightly lower in adult population - 13,9%. Study revealed, that hen's egg was the commonest implicated food for 6-7 years age group, hazel nut - for 13-14 years old age group followed by hen's egg. Walnut and hazel nut were most reported foods for adult population. The findings also revealed that food allergy is one of the most important risk factor for symptoms associated with asthma (OR-3,05; 95%CI 2.50-3.74), rhinoconjunctivitis (OR-2,85; 95%CI 2.24-3.64) and eczema (OR-5,42; 95%CI 4.08-7.18) in childhood. The data has provided the first epidemiological information related to food allergy among children and adults in Georgia. Results should serve as baseline information for food allergy screening, diagnosis and treatment. Our findings can also inform the public health officials on the disease burden and may offer some

    Full Text Available PURPOSE: To characterize refractive errors in Paraguayan children aged 5-16 years and investigate effect of age, gender, and ethnicity. METHODS:The study was conducted at 3 schools that catered to Mennonite, indigenous, and mixed race children. Children were examined for presenting visual acuity, autorefraction with and without cycloplegia, and retinoscopy. Data were analyzed for myopia and hyperopia (SE ≤-1 D or -0.5 D and ≥2 D or ≥3 D and astigmatism (cylinder ≥1 D. Spherical equivalent (SE values were calculated from right eye cycloplegic autorefraction data and analyzed using general linear modelling. RESULTS: There were 190, 118, and 168 children of Mennonite, indigenous and mixed race ethnicity, respectively. SE values between right/left eyes were nonsignificant. Mean visual acuity (VA without correction was better for Mennonites compared to indigenous or mixed race children (right eyes: 0.031, 0.090, and 0.102 logMAR units, respectively; P<0.000001. There were 2 cases of myopia in the Mennonite group (1.2% and 2 cases in the mixed race group (1.4% (SE ≤-0.5 D. The prevalence of hyperopia (SE ≥2 D was 40.6%, 34.2%, and 46.3% for Mennonite, indigenous and mixed race children. Corresponding astigmatism rates were 3.2%, 9.5%, and 12.7%. Females were slightly more hyperopic than males, and the 9-11 years age group was the most hyperopic. Mennonite and mixed race children were more hyperopic than indigenous children. CONCLUSIONS: Paraguayan children were remarkably hyperopic and relatively free of myopia. Differences with regard to gender, age, and ethnicity were small.

    The changing racial and ethnic diversity of the U.S. population along with delayed childbearing suggest that shifts in the demographic composition of gravidas are likely. It is unclear whether trends in the proportion of births to parous women in the United States have changed over the decades by race and ethnicity, reflecting parallel changes in population demographics. Singleton deliveries > or = 20 weeks of gestation in the United States from 1989 through 2000 were analyzed using data from the "Natality data files" assembled by the National Center for Health Statistics (NCHS). We classified maternal age into three categories; younger mothers (aged or = 40 years) and maternal race/ethnicity into three groups: blacks (non-Hispanic), Hispanics and whites (non-Hispanic). We computed birth rates by period of delivery across the entire population and repeated the analysis stratified by age and maternal race. Chi-squared statistics for linear trend were utilized to assess linear trend across three four-year phases: 1989-1992, 1993-1996 and 1997-2000. In estimating the association between race/ethnicity and parity status, the direct method of standardization was employed to adjust for maternal age. Over the study period, the total number of births to blacks and whites diminished consistently (p for trend fashion among the high (5-9 previous live births), very high (10-14 previous live births) and extremely high (> or = 15 previous live births) parity groups (p for trend < 0.001). After maternal age standardization, black and Hispanic women were more likely to have higher parity as compared to whites. Our findings demonstrate substantial variation in parity patterns among the main racial and ethnic populations in the United States. These results may help in formulating strategies that will serve as templates for optimizing resource allocation across the different racial/ethnic subpopulations in the United States.

    Full Text Available To evaluate the clinical manifestations and causative drugs associated with adverse drug reactions (ADRs spontaneously reported by community pharmacists and to compare the ADRs by age.ADRs reported to the Regional Pharmacovigilance Center of the Korean Pharmaceutical Association by community pharmacists from January 2013 to June 2014 were included. Causality was assessed using the WHO-Uppsala Monitoring Centre system. The patient population was classified into three age groups. We analyzed 31,398 (74.9% ADRs from 9,705 patients, identified as having a causal relationship, from a total pool of 41,930 ADRs from 9,873 patients. Median patient age was 58.0 years; 66.9% were female.Gastrointestinal system (34.4%, nervous system (14.4%, and psychiatric (12.1% disorders were the most frequent symptoms. Prevalent causative drugs were those for acid-related disorders (11.4%, anti-inflammatory products (10.5%, analgesics (7.2%, and antibacterials (7.1%. Comparisons by age revealed diarrhea and antibacterials to be most commonly associated with ADRs in children (p < 0.001, whereas dizziness was prevalent in the elderly (p < 0.001. Anaphylactic reaction was the most frequent serious event (19.7%, mainly associated with cephalosporins and non-steroidal anti-inflammatory drugs. Among 612 ADRs caused by nonprescription drugs, the leading symptoms and causative drugs were skin disorders (29.6% and non-steroidal anti-inflammatory drugs (16.2%, respectively.According to the community pharmacist reports, the leading clinical manifestations and causative drugs associated with ADRs in outpatients differed among age groups.

    [Purpose] In this study, we examined problematic behaviors of independent-walking and non-independent-walking handicapped children in the infant, school child and adolescent development phases, using the Japanese version of the Aberrant Behavior Checklist (ABC-J) to determine if such behaviors relate to their gross motor abilities. [Subjects and Methods] The subjects were 86 handicapped children who were receiving physical therapy. The subjects were classified into three groups by age. Using the Gross Motor Function Classification System (GMFCS), each group was further divided into an independent-walking group and non-independent-walking group. Thirteen physical therapists and 8 occupational therapists, who were treating the subject children, rated the subjects using the ABC-J. [Results] Significant differences were observed between the independent-walking and the non-independent-walking groups in the stereotypy and lethargy scores of infants. [Conclusion] For schoolchildren and adolescents, no significant differences were observed between the independent-walking and the non-independent-walking groups in their problematic behavior scores.

    Postmenopausal hormone therapy may have long-term effects on cognitive function depending on women's age. Postintervention follow-up was conducted with annual cognitive assessments of two randomized controlled clinical trial cohorts, beginning an average of 6-7 years after study medications were terminated: 1,376 women who had enrolled in the Women's Health Initiative when aged 50-54 years and 2,880 who had enrolled when aged 65-79 years. Women had been randomly assigned to 0.625mg/d conjugated equine estrogens (CEE) for those with prior hysterectomy (mean 7.1 years), CEE with 2.5mg/d medroxyprogesterone acetate for those without prior hysterectomy (mean 5.4 years), or matching placebos. Hormone therapy, when prescribed to women aged 50-54 years, had no significant long-term posttreatment effects on cognitive function and on changes in cognitive function. When prescribed to older women, it was associated with long-term mean (SE) relative decrements (standard deviation units) in global cognitive function of 0.081 (0.029), working memory of 0.070 (0.025), and executive function of 0.054 (0.023), all p therapy regimen, prior use, or years from last menstrual period. Mean intervention effects were small; however, the largest were comparable in magnitude to those seen during the trial's active intervention phase. CEE-based hormone therapy delivered near the time of menopause provides neither cognitive benefit nor detriment. If administered in older women, it results in small decrements in several cognitive domains that remain for many years.

    Synchrotron-based XRD spectra from rat bone of different age groups (w, 56 w and 78w), lumber vertebra at early stages of bone formation, Calcium hydroxyapatite (HAp) [Ca10(PO4)6(OH)2] bone fill with varying composition (60% and 70%) and bone cream (35-48%), has been acquired with 15keV synchrotron X-rays. Experiments were performed at Desy, Hamburg, Germany, utilizing the Resonant and Diffraction beamline (P9), with 15keV X-rays (λ=0.82666 A(0)). Diffraction data were quantitatively analyzed using the Rietveld refinement approach, which allowed us to characterize the structure of these samples in their early stages. Hydroxyapatite, received considerable attention in medical and materials sciences, since these materials are the hard tissues, such as bone and teeth. Higher bioactivity of these samples gained reasonable interest for biological application and for bone tissue repair in oral surgery and orthopedics. The results obtained from these samples, such as phase data, crystalline size of the phases, as well as the degree of crystallinity, confirm the apatite family crystallizing in a hexagonal system, space group P63/m with the lattice parameters of a=9.4328Å and c=6.8842Å (JCPDS card #09-0432). Synchrotron-based XRD patterns are relatively sharp and well resolved and can be attributed to the hexagonal crystal form of hydroxyapatite. All the samples were examined with scanning electron microscope at an accelerating voltage of 15kV. The presence of large globules of different sizes is observed, in small age groups of the rat bone (8w) and lumber vertebra (LV), as distinguished from, large age groups (56 and 78w) in all samples with different magnification, reflects an amorphous phase without significant traces of crystalline phases. Scanning electron microscopy (SEM) was used to characterize the morphology and crystalline properties of Hap, for all the samples, from 2 to 100μm resolution.

    Full Text Available Introduction. Recent evidence of safety and efficacy of Bone Marrow Mononuclear Cells (BMMNC in spinal cord injury makes the Bone Marrow (BM CD34+ percentage and the BMMNC count gain significance. The indices of BM that change with body mass index and aging in general population have been reported but seldom in Spinal Cord Injury (SCI victims, whose parameters of relevance differ from general population. Herein, we report the indices of BMMNC in SCI victims. Materials and Methods. BMMNCs of 332 SCI patients were isolated under GMP protocols. Cell count by Trypan blue method and CD34+ cells by flow cytometry were documented and analysed across ages and gender. Results. The average BMMNC per ml in the age groups 0–20, 21–40, 41–60, and 61–80 years were 4.71, 4.03, 3.67, and 3.02 million and the CD34+ were 1.05%, 1.04%, 0.94%, and 0.93% respectively. The decline in CD34+ was sharp between 20–40 and 40–60 age groups. Females of reproductive age group had lesser CD34+. Conclusion. The BMMNC and CD34+ percentages decline with aging in SCI victims. Their lower values in females during reproductive age should be analysed for relevance to hormonal influence. This study offers reference values of BMMNC and CD34+ of SCI victims for successful clinical application.

    Full Text Available The purpose of this study was to describe the evolution of morphological, physiological and skating performance profiles of elite age-group ice hockey players based on repeated measures spread over one season. In addition, the results of fitness tests and training programs performed in off-ice conditions and their relationship with skating performance were analyzed. Eighteen high level age-group ice hockey players (13.1 ± 0.6 years were assessed off and on-ice at the beginning and at the end of the hockey season. A third evaluation was also conducted at the beginning of the following hockey season. The players were taller, heavier, and showed bone breadths and muscle girths above the reference population of the same age. Muscular variables improved significantly during and between the two hockey seasons (p < 0.05. However, maximal aerobic power improved only during the off-season. All skating performance tests exhibited significant enhancements during the hockey season, but not during the off-season where some degradation was observed. Finally, weak observed variances (generally <20% of the explained variance between physiological variables measured off-ice and on-ice skating performance tests indicated important gaps, both in the choice of the off-ice assessment tools as well as in training methods conventionally used. The reflection on the best way to assess and train hockey players certainly deserves to be continued.

    Schwannoma is a benign, encapsulated perineural tumour originating from the schwann cells of the neural sheath of peripheral motor and sensory nerves. It may develop at any age but is extremely rare in paediatric age group. The tumour is frequently located on the head and neck region, the tongue being the most common site followed by the palate, floor of mouth, buccal mucosa, lips and jaws. Schwannomas rarely occur in the lip area and it is exceedingly rare in the upper lip. The lesion is usually solitary but can be multiple when associated with neurofibromatosis. The diagnosis is usually confirmed after biopsy and anti-S100 protein immuno-histochemical staining is usually used to identify the tumour. In the present study the patient was a 14-year-old young girl with the schwannoma on the upper lip which is probably the third such case in a paediatric age group being reported and was excised without any recurrence at 2 year after excision.

    The purpose of this study was to evaluate the metabolic processes in women with diabetes mellitus type 2 of different age groups. It is established that hyperglycemia in aged women is characterized by the development of pronounced oxidative stress, which is the result of changes in the primary structure of protein molecules due to non enzymatic glycosylation of amino acid residues in the active sites. It is known that observed depletion of reduced glutathione pool is associated with high risk of genotoxicity, because it correlates with activation of mitochondrial, chromatin dysfunction and fragmentation of the DNA. In addition, hydroperoxides of polyunsaturated fatty acids formation leads to necrosis and apoptosis. It can be assumed that the diabetes mellitus type 2 triggers processes of apoptosis, which leads to the activation of aging programs and increase the mortality of patients. Obviously, the change in the concentration of thiol antioxidants, as well as the change in concentration of LPO molecular products may be one of the criteria for evaluation of aging and the efficiency of the treatment of patients.

    Full Text Available Secondary organic aerosol (SOA formation from a volatile organic compound (VOC involves multiple generations of oxidation that include functionalization and fragmentation of the parent carbon backbone and likely particle-phase oxidation and/or accretion reactions. Despite the typical complexity of the detailed molecular mechanism of SOA formation and aging, a relatively small number of functional groups characterize the oxidized molecules that constitute SOA. Given the carbon number and set of functional groups, the volatility of the molecule can be estimated. We present here a functional group oxidation model (FGOM that represents the process of SOA formation and aging. The FGOM contains a set of parameters that are to be determined by fitting of the model to laboratory chamber data: total organic aerosol concentration, and O : C and H : C atomic ratios. The sensitivity of the model prediction to variation of the adjustable parameters allows one to assess the relative importance of various pathways involved in SOA formation. An analysis of SOA formation from the high- and low-NOx photooxidation of four C12 alkanes (n-dodecane, 2-methylundecane, hexylcyclohexane, and cyclododecane using the FGOM is presented, and comparison with the statistical oxidation model (SOM of Cappa et al.

    We have observed and spatially resolved a set of seven A-type stars in the nearby Ursa Major moving group with the Classic, CLIMB, and PAVO beam combiners on the CHARA Array. At least four of these stars have large rotational velocities ($v \\sin i$ $\\gtrsim$ 170 $\\mathrm{km~s^{-1}}$) and are expected to be oblate. These interferometric measurements, the stars' observed photometric energy distributions, and $v \\sin i$ values are used to computationally construct model oblate stars from which stellar properties (inclination, rotational velocity, and the radius and effective temperature as a function of latitude, etc.) are determined. The results are compared with MESA stellar evolution models (Paxton et al. 2011, 2013) to determine masses and ages. The value of this new technique is that it enables the estimation of the fundamental properties of rapidly rotating stars without the need to fully image the star. It can thus be applied to stars with sizes comparable to the interferometric resolution limit as oppose...

    The Strategic Implementation Plan of the European Innovation Partnership on Active and Healthy Ageing (EIP on AHA) proposed six Action Groups. After almost three years of activity, many achievements have been obtained through commitments or collaborative work of the Action Groups. However, they have often worked in silos and, consequently, synergies between Action Groups have been proposed to strengthen the triple win of the EIP on AHA. The paper presents the methodology and current status of the Task Force on EIP on AHA synergies. Synergies are in line with the Action Groups' new Renovated Action Plan (2016-2018) to ensure that their future objectives are coherent and fully connected. The outcomes and impact of synergies are using the Monitoring and Assessment Framework for the EIP on AHA (MAFEIP). Eight proposals for synergies have been approved by the Task Force: Five cross-cutting synergies which can be used for all current and future synergies as they consider overarching domains (appropriate polypharmacy, citizen empowerment, teaching and coaching on AHA, deployment of synergies to EU regions, Responsible Research and Innovation), and three cross-cutting synergies focussing on current Action Group activities (falls, frailty, integrated care and chronic respiratory diseases).

    To evaluate if there is a relation between age groups, menarche, menstrual cycles and previous pregnancies with the success of weight loss in obese patients at a nutrition clinic. A clinical intervention study was conducted among overweight and obese patients who consulted a nutrition clinic in Barranquilla (Colombia) for the purpose of nutritional assessment. They were subject to a personalized weekly follow-up consultation over the course of 16 weeks in which food consumption patterns, anthropometric measures, body image and self-perception were registered. A total of 135 patients were evaluated. 41 (30,4%) of whom did not complete the study. 69,6% patients did lose weight and 83,7% did lose waist. These losses are lower in older ages (95,5% at.

    Full Text Available There is a long running debate on the significance of ethnic residential segregation levels in Britain. These phenomena have been related to the extent of community cohesion in British cities, and particularly to the riots of 2001 in the north of England. Further light is cast on these issues by examining ethnic segregation by age in the case of Bradford, the location of the largest riot. Both the dissimilarity index and the exposure index are used to consider relations between the White British and the largest minorities at ward level and at census output area level. The level of segregation is shown to vary with age, usually in a consistent direction. The direction varies between ethnic groups however.

    Background Congenital aortic valve fusion is associated with aortic dilation, aneurysm and rupture in girls and women with Turner syndrome (TS). Our objective was to characterize aortic valve structure in subjects with TS, and determine the prevalence of aortic dilation and valve dysfunction associated with different types of aortic valves. Methods and Results The aortic valve and thoracic aorta were characterized by cardiovascular magnetic resonance imaging in 208 subjects with TS in an IRB-approved natural history study. Echocardiography was used to measure peak velocities across the aortic valve, and the degree of aortic regurgitation. Four distinct valve morphologies were identified: tricuspid aortic valve (TAV) 64%(n=133), partially fused aortic valve (PF) 12%(n=25), bicuspid aortic valve (BAV) 23%(n=47), and unicuspid aortic valve (UAV) 1%(n=3). Age and body surface area (BSA) were similar in the 4 valve morphology groups. There was a significant trend, independent of age, towards larger BSA-indexed ascending aortic diameters (AADi) with increasing valve fusion. AADi were (mean +/− SD) 16.9 +/− 3.3 mm/m2, 18.3 +/− 3.3 mm/m2, and 19.8 +/− 3.9 mm/m2 (p<0.0001) for TAV, PF and BAV+UAV respectively. PF, BAV, and UAV were significantly associated with mild aortic regurgitation and elevated peak velocities across the aortic valve. Conclusions Aortic valve abnormalities in TS occur with a spectrum of severity, and are associated with aortic root dilation across age groups. Partial fusion of the aortic valve, traditionally regarded as an acquired valve problem, had an equal age distribution and was associated with an increased AADi. PMID:24084490

    Full Text Available Over the past few years the population of older drivers has substantially increased across the United States. Older drivers are a group of special interest because of their potential age-related deficiencies. It is essential to understand their driving behavior and adjust the conditions of roadway systems according to their requirements. Likewise, driving behavior of older drivers needs to be considered in order to adequately estimate capacities at intersections. In the past few years, research projects were performed by the University of South Florida to analyze the differences of driving behavior among different driver age groups. Typically, the driving behavior of older drivers was evaluated by analyzing their start-up lost time and saturation headway at signalized intersections as compared to young and mid-age driver groups. Research results were based on data collected from signalized intersections with different land-use types. These intersections are located in west and central Florida where the elderly population has been increasing rapidly in recent years. From the results it was found that the presence of older drivers significantly reduced intersection capacity at all study sites because of their higher lost times and lower saturation flow rates. Therefore, driving behavior of older drivers should be considered in designing intersections located in places with a significant older driver population. In the research, models were developed to predict start-up lost time and saturation headway values generated by older drivers. Then, the variation in capacities with an increasing percentage of older drivers in the traffic stream was modeled. Finally, adjustment factors for different percentages of older drivers were developed to adjust intersection capacity. These factors are believed to account for the presence of older drivers in the traffic stream. The adjustment factors may be used in capacity analysis and design procedures for

    A highly diversified, advanced and exceptionally well preserved microfossil assemblage, dominated by a planktic community,has been recorded from petrographic thin sections of chert belonging to the Sirbu Shale Formation,Bhander group,upper Vindhyans,Rajasthan.Recently, it was noticed that the assemblage also contains well preserved,large-sized acanthomorphic acritarchs, Trachyhystrichosphaera considered to be an age-marker microfossil of the Cryogenian (850 –630 Ma).It is reported for the first time from any Indian microfossil assemblage of Proterozoic succession.The other microfossils of the Sirbu Shale Formation are:well preserved simple,small and large-sized sphaeromorphs;complex acanthomorphs,cyanobacterial community;especially a very small-sized but exceptionally well preserved Obruchevella ,a form resembling Volvox colonies; cf.vase-shaped microfossils and morphologies,possibly inclining towards fungal affinity,or lichen- like symbiotic associations of algae and fungi.Till date, Trachyhystrichosphaera has so far not been reported from successions older than the Tonian (1000 –850 Ma).It is believed that acanthomorphs attained maximum size in Ediacaran (630 –542 Ma),and further decreased in size in the Cambrian.The global paleontological literature indicates that Trachyhystrichosphaera ranges in age from Tonian –Ediacaran (1000 –542 Ma). The present record of Trachyhystrichosphaera as well as the earlier studies of micro and megascopic life of the Bhander Group in general and the Sirbu Shale in particular (aided by the absence of any Cambrian fossil record)indicate that in all possibilities,age of the Sirbu Shale should lie near Cryogenian (850 –630 Ma)and the uppermost Bhander group,may incline towards the Ediacaran (630 –542 Ma).

    In this paper we show a new method of using automatic age and gender recognition to recommend a sequence of multimedia items to a home TV audience comprising multiple viewers. Instead of relying on explicitly provided demographic data for each user, we define an audio-based demographic group......, which itself is the input to a recommender system. The recommender system finds the content items whose demographics best match the group profile. We tested the effectiveness of the system for several typical home audience configurations. In a survey, users were given a configuration and asked to rate...... a set of advertisements on how well each advertisement matched the configuration. Unbeknown to the subjects, half of the adverts were recommended using the derived audio demographics and the other half were randomly chosen. The recommended adverts received a significantly higher median rating of 7...

    2013-09-01

    Full Text Available It is proposed from this investigative study to analyze the expectations of entering students of technical course in Agriculture, with different age groups, as the contribution of professional education for its professionalism and continued education. A mixed questionnaire was applied and, to evaluate the data, the group was divided into two categories. Differences in their school history were evidenced, as well as their expectations regarding the course. The younger students have a tendency to be conducting the course because they could not join a college. On the other hand, older students seek in technical knowledge to act professionally or to be a complement of their graduation. Thus, the teachers and the school need to strengthen the possibilities that the course provide, in order to stimulate the course ending, in order to form professionals to contribute to the community.

    Sex estimation is used in forensic anthropology to assist the identification of individual remains. However, the estimation techniques tend to be unique and applicable only to a certain population. This paper analyzed sex estimation on living individual child below 19 years old using the length of 19 bones of left hand applied for three classification techniques, which were Discriminant Function Analysis (DFA), Support Vector Machine (SVM) and Artificial Neural Network (ANN) multilayer perceptron. These techniques were carried out on X-ray images of the left hand taken from an Asian population data set. All the 19 bones of the left hand were measured using Free Image software, and all the techniques were performed using MATLAB. The group of age "16-19" years old and "7-9" years old were the groups that could be used for sex estimation with as their average of accuracy percentage was above 80%. ANN model was the best classification technique with the highest average of accuracy percentage in the two groups of age compared to other classification techniques. The results show that each classification technique has the best accuracy percentage on each different group of age. Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.

    The widespread presence of organochlorine (OC) pesticides in human samples may be explained by the environmental exposure of the population. Foods are considered a constant source of exposure, despite compliance with maximum permitted residue levels. This study aimed to examine the relationship between nutritional habits of women in Southeast Spain and their serum concentrations of OCs. A semi-quantitative questionnaire was used to estimate the frequency of consumption of foods by two age groups of women, pre-menopausal (Pre-M) and post-menopausal (Post-M), and their serum pesticide levels were measured by gas chromatography (GC) with electron capture detector and confirmed by GC and mass spectrometry. The Pre-M group showed significantly higher serum concentrations of all OCs studied with the exception of DDE. The groups significantly differed in consumption of all food groups with the exception of fruit. In the Pre-M group, the mean serum p,p-DDT concentration was significantly associated with milk/yoghurt (p < 0.045) and red meat (p < 0.023), serum o,p-DDT with red meat (p < 0.049), serum aldrin with eggs (p < 0.038) and poultry (p < 0.024), and serum DDE with eggs (p < 0.025). In the Post-M group, serum lindane was associated with fresh and cured cheese (p < 0.001), red meat (p < 0.001) and white and oily fish (p < 0.001), and both serum DDE and dieldrin were associated with fresh cheese, cured cheese, red meat, and white and oily fish (p < 0.001). These results confirm foods as a source of human exposure to persistent organic molecules. Consideration should be given to the reduction of permitted residue levels to minimize this threat to human and animal health.

    Background There is a growing interest in empowering older adults to age in place by deploying various types of technology (ie, eHealth, ambient assisted living technology, smart home technology, and gerontechnology). However, initiatives aimed at implementing these technologies are complicated by the fact that multiple stakeholder groups are involved. Goals and motives of stakeholders may not always be transparent or aligned, yet research on convergent and divergent positions of stakeholders is scarce. Objective To provide insight into the positions of stakeholder groups involved in the implementation of technology for aging in place by answering the following questions: What kind of technology do stakeholders see as relevant? What do stakeholders aim to achieve by implementing technology? What is needed to achieve successful implementations? Methods Mono-disciplinary focus groups were conducted with participants (n=29) representing five groups of stakeholders: older adults (6/29, 21%), care professionals (7/29, 24%), managers within home care or social work organizations (5/29, 17%), technology designers and suppliers (6/29, 21%), and policy makers (5/29, 17%). Transcripts were analyzed using thematic analysis. Results Stakeholders considered 26 different types of technologies to be relevant for enabling independent living. Only 6 out of 26 (23%) types of technology were mentioned by all stakeholder groups. Care professionals mentioned fewer different types of technology than other groups. All stakeholder groups felt that the implementation of technology for aging in place can be considered a success when (1) older adults’ needs and wishes are prioritized during development and deployment of the technology, (2) the technology is accepted by older adults, (3) the technology provides benefits to older adults, and (4) favorable prerequisites for the use of technology by older adults exist. While stakeholders seemed to have identical aims, several underlying

    The authors examined in 125 young sexually mature and in 50 young sexually immature male rabbits of a New Zealand improved Bulgarian breed the following serum lipid indices: total lipids, total and free cholesterol triglycerides, phospholipids, cholesterol and triglyceride content of VLDL (very low density lipoproteins), LDL (high density lipoproteins), HDL (high density lipoproteins) and the percentage concentration of serum lipopropteins, examined electrophoretically. The concentrations of the examined lipid and lipoprotein fractions in the sera of both age groups of rabbits showed asymetrical distribution. The hystograms of the total lipids and total cholesterol in younger animals was excluded. The logarithnictrandsformation of asymetricaly distributed concentrations of the examined fractions normalized their distribution in a part of them. The authors determined the ranges of the norm with the help of the percentile analysis in the remaining indices with asymetric distribution. Serum lipid and lipoprotein profile revealed substantial differnces in both age groups of animals. Serum lipids and lipoproteins in young sexually mature male rabbits differed from those of a man not only by their absolute concentrations, but also by their structural characteristics.

    Oxycodone is commonly used to treat severe pain in adults and children. It is extensively metabolized in the liver in adults, but the maturation of metabolism is not well understood. Our aim was to study the metabolism of oxycodone in cryopreserved human hepatocytes from different age groups (3 days, 2 and 5 months, 4 years, adult pool) and predict hepatic plasma clearance of oxycodone using these data. Oxycodone (0.1, 1, and 10 μM) was incubated with hepatocytes for 4 h, and 1 μM oxycodone also with CYP3A inhibitor ketoconazole (1 μM). Oxycodone and noroxycodone concentrations were determined at several time points with liquid chromatography–mass spectrometry. In vitro clearance of oxycodone was used to predict hepatic plasma clearance, using the well-stirred model and published physiological parameters. Noroxycodone was the major metabolite in all batches and ketoconazole inhibited the metabolism markedly in most cases. A clear correlation between in vitro oxycodone clearance and CYP3A4 activity was observed. The predicted hepatic plasma clearances were typically much lower than the published median total plasma clearance from pharmacokinetic studies. The data suggests that there are no children-specific metabolites of oxycodone. Moreover, CYP3A activity seems to be the major determinant in metabolic clearance of oxycodone regardless of age group or individual variability in hepatocyte batches. PMID:22291644

    Interview data gathered during 2 surveys in Anhui and Shejiang Provinces in 1986 and 1987 are used to depict changes in the social status and life situation of rural women in China in 3 age groups, 18-36, 37-55, and 56 and over. For the younger women, marriage increasingly is a result of discussion with parents, not arrangement, but 3rd-party introductions are increasing. They are active in household and township enterprises and aspire to more education and economic independence. The middle-aged group experienced war and revolution and now work nonstop under the responsibility system of household production, aspiring to university education for sons and enterprise work for daughters. The older women, while supported by their sons, live a frugal existence. In general, preference for sons is still prevalent and deep-seated. At the same time, the bride price and costs of marriage are increasing and of widespread concern. Rural socioeconomic growth is required before Confucian traditions are overcome.

    Deoxynivalenol (DON) is the most common mycotoxin in Norwegian cereals, and DON is detected in most samples of crude cereal grain and cereal food commodities such as flour, bran, and oat flakes. The Norwegian Scientific Committee for Food Safety assessed the risk for adverse effects of deoxynivalenol (DON) in different age groups of the domestic population. This review presents the main results from the risk assessment, supplemented with some recently published data. Impairment of the immune system together with reduced feed intake and weight gain are the critical effects of DON in experimental animals on which the current tolerable daily intake was established. Based on food consumption and occurrence data, the mean exposure to DON in years with low and high levels of DON in the flour, respectively, were in the range of or up to two times the Tolerable Daily Intake (TDI) in 1-year-old infants and 2-year-old children. In years with high mean DON concentration, the high (95th-percentile) exposure exceeded the TDI by up to 3.5 times in 1-, 2- , 4-, and 9-year-old children. The assessment concluded that exceeding the TDI in infants and children is of concern. The estimated dietary DON intakes in adolescent and adult populations are in the range of the TDI or below, and are not a health concern. Acute human exposure to DON is not of concern in any age group. PMID:28165414

    Radon 222 is a natural radioactive element with a half-life of 3.8 days. It is odorless and colorless as well as water-soluble. Consuming waters which contain high concentration of 222Rn would increase the effective dose received by different age groups. It would also be followed by an increased prevalence of cancer. In this research, 72 samples of the most commonly used bottled water in Bandar Abbas were collected in 3 consecutive months, May, June and July of 2013. Concentration 222Rn of was measured by radon-meter model RTM166-2. The effective dose received by the 4 age groups, male and female adults as well as children and infants was estimated using the equation proposed by UNSCEAR. The results revealed that the mean and range concentration of 222Rn in bottled waters were 641±9 Bq/m3 and 0-901 Bq/m3, respectively. The mean concentration of 222Rn in the well-known Marks followed this Zam Zam>Bishe>Koohrng>Dassani>Christal>Polour>Damavand>Sivan. Infants were observed to receive a higher effective dose than children. The highest and lowest effective dose received was found to belong to male adults and children, respectively.

  15. Fresh frozen plasma in the pediatric age group and in congenital coagulation factor deficiency.

    Generally, the rules of good practice in transfusion medicine apply also to the pediatric age group. However, the frequency of specific diseases that might necessitate the administration of fresh frozen plasma (FFP) differs from that in adults. Physiologic differences to the later age exist in the neonatal period and in young infants, especially with respect to the hemostatic system, that must be recognized when considering administration of FFP. The plasma levels of many procoagulant factors and important anticoagulants are lower in neonates than in other age groups. Despite these findings, healthy neonates show no easy bruising, no increased bleeding during surgery, and excellent wound healing. The same discrepancy obtains between in vitro and clinical findings with primary hemostasis in neonates. The good primary hemostasis in neonates despite poor in vitro platelet function seems to be due mainly to a very high von Willebrand factor and the presence of more high-multimeric subunits of von Willebrand factor than later in life. We must assume that these particular plasma levels of procoagulant and anticoagulant proteins are essential for the correct function of neonatal hemostasis. Evidence that the hemostatic system of neonates works best with physiologic concentrations of procoagulants and anticoagulants can also be inferred from studies where the administration of clotting factor concentrates gave poor results.Since healthy neonates and young infants have excellent hemostasis, there is absolutely no indication to 'correct' these values to adult's norms prior to invasive procedures by administering FFP. Indications for FFP, met more frequently in the pediatric age group than later in life, are exchange transfusion and extracorporeal membrane oxygenation. Indications applying equally to adults are other extracorporeal life support systems, disseminated intravascular coagulation, hepatic coagulopathy, and 'complex unclear coagulopathies'.

    Gender differences in autobiographical memory emerge in some data collection paradigms and not others. The present study included an extensive analysis of gender differences in autobiographical narratives. Data were collected from 196 participants, evenly split by gender and by age group (emerging adults, ages 18-29, and young adults, ages 30-40). Each participant reported four narratives, including an event that had occurred in the last 2 years, a high point, a low point, and a self-defining memory. Additionally, all participants completed self-report measures of masculine and feminine gender typicality. The narratives were coded along six dimensions-namely coherence, connectedness, agency, affect, factual elaboration, and interpretive elaboration. The results indicated that females expressed more affect, connection, and factual elaboration than males across all narratives, and that feminine typicality predicted increased connectedness in narratives. Masculine typicality predicted higher agency, lower connectedness, and lower affect, but only for some narratives and not others. These findings support an approach that views autobiographical reminiscing as a feminine-typed activity and that identifies gender differences as being linked to categorical gender, but also to one's feminine gender typicality, whereas the influences of masculine gender typicality were more context-dependent. We suggest that implicit gendered socialization and more explicit gender typicality each contribute to gendered autobiographies.

    Full Text Available Introduction: Among endocrine disorders commonly encountered in pediatric age group, thyroid diseases are more frequent. Congenital hypothyroidism is one of the major problems in this age with worldwide incidence of 1:3000-4000 live birth and in India it is 1:2500-2800. Objectives: The aim of this study is to know the prevalence of thyroid diseases in newborn and children by hormonal evaluation. Methodology: We have studied 50 children suspected of having signs and symptoms of thyroid diseases. Hormonal evaluation was done by the estimation of serum TSH, T3 and T4. Results: Out of total 50 children, 16 were detected with abnormal hormone level and diagnosed having thyroid diseases. Out of 16 affected children, 4 had congenital hypothyroidism (25%, 6 had subclinical or acquired hypothyroidism (37.5%, 3 had autoimmune thyroiditis (18.75% and 3 had goiter with graves disease (18.75%. Conclusion: Congenital hypothyroidism is one of the major preventable thyroid disease if diagnosed early. Other thyroid diseases commonly seen in pediatric age are subclinical hypothyroidism, autoimmune thyroiditis, goiter and rarely hyperthyroidism. [Natl J Med Res 2013; 3(4.000: 367-370

    Full Text Available Introduction: CNS tumors are the most common solid tumors in children. Tumors of the central nervous system can be divided into primary intracranial tumours that arise from parenchyma of brain, pituitary gland, covering of brain & secondary intracranial tumours which represent local extension from regional tumours or metastasis from primary malignancy in the body. The most common location of the brain tumours in childhood is below the tentorium within the posterior cranial fossa. Materials and methods: Surgical specimen of central nervous system of children (0 to 14 year of age group received from August 2013 to November 2015, in the Tertiary care center, Ahmedabad were studied with keeping the following features in mind: Age, Sex and site of tumours. Results: Fifty eight cases of central Nervous system Tumours between the age of 0 to 14 years over a period of 2.5 years at civil hospital, Ahmedabad were studied. Incidence were more common in male (60.34% than female(39.66% 89.65% were intracranial to 10.35% were intraspinal tumours.Commonly encountered tumour in descending order of frequency were Medulloblastoma (27.58%, astrocytoma (24.13%, Ependymoma (20.68%. All medulloblastomas arose infratentorial, schwannomas arose intraspinal and meningiomas in cranial cavity are supratentorial. Conclusion: CNS Tumors constitute a large proportion of cancers in childhood. They differ from adult CNS tumors both histologically and location wise. Site of the tumor is significant as it can lead to fatal consequences

    Full Text Available ABSTRACT: Qualitative study which aims was to describe the emotions in elderly life and to debate the relation between emotions and elderly health. The study was developed in a third age group at Sao Gonçalo city – RJ by participant observation and semi-structured interviews with ten elderly people. After the information analysis it was possible to identify the category "The Pendulum of Emotions" and two complementary subjects: rising and descending movement of emotions on living. The elderly evidenced that their emotions represents a continuous movement which reflects straightly to the feeling of being or not healthy and living well the third age is having autonomy of daily activities and freedom to participate of leisure and physical activities. Thus, the human being needs to valorize all the stages of his life, because the process of becoming old starts from the moment we were born and the quality of life is a daily conquest in this way.

    Full Text Available Background.  Associated injury is a worldwide social and economic problem. Age related aspects of endogenous intoxication are not studied comprehensively. Annually, from 44 000 to 65 000 citizens die because of traumatic injuries. As a result, this number increased by 32.6% for the last 10 years.     The detoxification system, as a component of the functional systems of the organism, experiences significant changes in case of polytrauma. Objective. The study was aimed to discover pathogenetic peculiarities of the multiple trauma in age aspect in different disease periods and to explore the level of endogenous intoxication in this condition. Methods. The experiments were performed on 72 white male rats aged 3, 6 and 12 months, which underwent simulation of severe skeletal trauma and examination of the contents of middle mass molecules and endogenous intoxication index (markers of endogenous intoxication in 1, 4 and 24 hours after the associated injury. Results. The most significant increase of the middle mass molecules was fixed in 24 hours after modeling of severe skeletal injuries in all groups of animals, especially it was the most pronounced in 12-month-old animals. The erythrocyte intoxication index reached the highest level in 4 hours after the injury, its increase was most significant in sexually mature adult animals. Conclusion. A significant increasing of endogenous intoxication markers in 12-month-old rats, if compared to 3- and 6-month-old animals, can be caused by the decrease in compensatory protection mechanisms.

    Ageing decreases exercise performance and is frequently accompanied by reductions in cognitive performance. Deterioration in the physiological capacity to stand, locomote and exercise can manifest itself as falling over and represents a significant deterioration in sensorimotor control. In the elderly, falling leads to serious morbidity and mortality with major societal costs. Measurement of a suite of physiological capacities that are required for successful motor performance (including vision, muscle strength, proprioception and balance) has been used to produce a physiological profile assessment (PPA) which has been tracked over the age spectrum and in different diseases (e.g. multiple sclerosis, Parkinson's disease). As well as measures of specific physiological capacities, the PPA generates an overall 'score' which quantitatively measures an individual's cumulative risk of falling. The present review collates data from the PPA (and the physiological capacities it measures) as well as its use in strategies to reduce falls in the elderly and those with different diseases. We emphasise that (i) motor impairment arises via reductions in a wide range of sensorimotor abilities; (ii) the PPA approach not only gives a snapshot of the physiological capacity of an individual, but it also gives insight into the deficits among groups of individuals with particular diseases; and (iii) deficits in seemingly restricted and disparate physiological domains (e.g. vision, strength, cognition) are funnelled into impairments in tasks requiring upright balance. Motor impairments become more prevalent with ageing but careful physiological measurement and appropriate interventions offer a way to maximise health across the lifespan.

    A priority of the Global Polio Eradication Initiative (GPEI) 2013-2018 strategic plan is to evaluate the potential impact on polio eradication resulting from expanding one or more Supplementary Immunization Activities (SIAs) to children beyond age five-years in polio endemic countries. It has been hypothesized that such expanded age group (EAG) campaigns could accelerate polio eradication by eliminating immunity gaps in older children that may have resulted from past periods of low vaccination coverage. Using an individual-based mathematical model, we quantified the impact of EAG campaigns in terms of probability of elimination, reduction in polio transmission and age stratified immunity levels. The model was specifically calibrated to seroprevalence data from a polio-endemic region: Zaria, Nigeria. We compared the impact of EAG campaigns, which depend only on age, to more targeted interventions which focus on reaching missed populations. We found that EAG campaigns would not significantly improve prospects for polio eradication; the probability of elimination increased by 8% (from 24% at baseline to 32%) when expanding three annual SIAs to 5-14 year old children and by 18% when expanding all six annual SIAs. In contrast, expanding only two of the annual SIAs to target hard-to-reach populations at modest vaccination coverage-representing less than one tenth of additional vaccinations required for the six SIA EAG scenario-increased the probability of elimination by 55%. Implementation of EAG campaigns in polio endemic regions would not improve prospects for eradication. In endemic areas, vaccination campaigns which do not target missed populations will not benefit polio eradication efforts.

    Full Text Available We tested whether indomethacin or rosiglitazone treatment could rejuvenate spatial ability and hippocampal neurogenesis in aging rats. Young (4 mo; n = 30, middle-aged (12 mo; n = 31, and aged (18 mo; n = 31 male Fischer 344 rats were trained and then tested in a rapid acquisition water maze task and then fed vehicle (500 μl strawberry milk, indomethacin (2.0 mg/ml, or rosiglitazone (8.0 mg/ml twice daily for the remainder of the experiment. A week after drug treatment commenced, the rats were given 3 daily BrdU (50 mg/kg injections to test whether age-related declines in neurogenesis were reversed. One week after the final BrdU injection (~2.5 weeks after the 1st water maze session, the rats were trained to a find novel hidden water maze platform location, tested on 15 min and 24 h probe trials and then killed 24 h later. During the first water maze session, young rats outperformed aged rats but all rats learned information about the hidden platform location. Middle-aged and aged rats exhibited better memory probe trial performances than young rats in the 2nd water maze session and indomethacin improved memory probe trial performances on the 2nd vs. 1st water maze session in middle-aged rats. Middle-aged rats with more new neurons had fewer phagocytic microglia and exhibited better hidden platform training trial performances on the 2nd water maze session. Regardless of age, indomethacin increased new hippocampal neuron numbers and both rosiglitazone and indomethacin increased subependymal neuroblasts/neuron densities. Taken together, our results suggest the feasibility of studying the effects of longer-term immunomodulation on age-related declines in cognition and neurogenesis.

    Full Text Available Context: Unmet need for family planning (FP, which refers to the condition in which there is the desire to avoid or post-pone child bearing, without the use of any means of contraception, has been a core concept in the field of international population for more than three decades. Objectives: The very objective of this study is to determine the prevalence of "unmet need for FP" and its socio-demographic determinants among married reproductive age group women in Chidambaram. Materials and Methods: The study was a community-based cross-sectional study of married women of the reproductive age group, between 15 and 49 years. The sample size required was 700. The cluster sampling method was adopted. Unmarried, separated, divorced and widows were excluded. Results: The prevalence of unmet need for FP was 39%, with spacing as 12% and limiting as 27%. The major reason for unmet need for FP among the married group was 18%, for low perceived risk of pregnancy, 9%, feared the side effects of contraception 5% lacked information on contraceptives, 4% had husbands who opposed it and 3% gave medical reasons. Higher education, late marriage, more than the desired family size, poor knowledge of FP, poor informed choice in FP and poor male participation were found to be associated with high unmet need for FP. Conclusion: Unmet need for younger women was spacing of births, whereas for older women, it was a limitation of births. Efforts should be made to identify the issues in a case by case approach. Male participation in reproductive issues should be addressed.

    We evaluated the effect of barnidipine, a dihydropyridine calcium antagonist, administered once daily in the morning in a dose of 5, 10, or 15 mg on ambulatory blood pressure (BP) in 34 patients (51.3+/-9.6 years). Hypertension was diagnosed based on the clinic BP. The patients were classified into groups according to the ambulatory BP: group 1, dippers with true hypertension; group 2, nondippers with true hypertension; group 3, dippers with false hypertension; and Group 4, nondippers with false hypertension. Barnidipine reduced the clinic systolic BP (SBP) and diastolic BP (DBP) in all groups and significantly reduced the average 24 h ambulatory BP (133.0+/-16.5/90.7+/-12.3 mm Hg v 119.7+/-13.7/81.8+/-10.3 mm Hg, P Barnidipine significantly reduced the daytime ambulatory SBP in groups 1, 2, and 3, but not in group 4, and significantly reduced daytime ambulatory DBP in group 1 but not in groups 2, 3, and 4. Barnidipine significantly reduced the nighttime ambulatory SBP only in group 2 and the nighttime ambulatory DBP in groups 2 and 4. Once-a-day administration of barnidipine influenced 24 h BP on true hypertensives (the ratio of the trough to peak effect > 50%), but had minimal effect on low BP such as the nocturnal BP in dippers and the ambulatory BP in false hypertensives. These findings suggest that barnidipine can be used safely in patients with isolated clinic ("white coat") hypertension and in those with dipping patterns of circadian BP variation whose nocturnal BP is low before treatment.

    Middle Ordovician age Chickamauga Group carbonates crop out along the Birmingham and Murphrees Valley anticlines in central Alabama. The macrofossil contents on exposed surfaces of seven bioherms have been counted to determine their various paleontologic characteristics. Twelve groups of organisms are present in these bioherms. Dominant organisms include bryozoans, algae, brachiopods, sponges, pelmatozoans, stromatoporoids and corals. Minor accessory fauna include predators, scavengers and grazers such as gastropods, ostracods, trilobites, cephalopods and pelecypods. Vertical and horizontal niche zonation has been detected for some of the bioherm dwelling fauna. No one bioherm of those studied exhibits all 12 groups of organisms; rather, individual bioherms display various subsets of the total diversity. Statistical treatment (G-test) of the diversity data indicates a lack of statistical homogeneity of the bioherms, both within and between localities. Between-locality population heterogeneity can be ascribed to differences in biologic responses to such gross environmental factors as water depth and clarity, and energy levels. At any one locality, gross aspects of the paleoenvironments are assumed to have been more uniform. Significant differences among bioherms at any one locality may have resulted from patchy distribution of species populations, differential preservation and other factors.

    To verify the metabolic responses of oxygen consumption (V[Combining Dot Above]O2), heart rate (HR), blood lactate concentrations [La], and rate of perceived exertion (RPE) when swimming at an intensity corresponding to the critical velocity (CV) assessed by a 4-parameter model (CV4par), and to check the reliability when using only a single 400-m maximal front crawl bout (T400) for CV4par assessment in age-group swimmers. Ten age-group swimmers (14-16 years old) performed 50-, 100-, 200-, 400- (T400), 800-, and 1,500-m maximal front crawl bouts to calculate CV4par. V[Combining Dot Above]O2, HR, [La], and RPE were measured immediately after bouts. Swimmers then performed 3 × 10-minute front crawl (45 seconds rest) at CV4par. V[Combining Dot Above]O2, HR, [La], and RPE were measured after 10 minutes of rest (Rest), warm-up (Pre), each 10-minute repetition, and at the end of the test (Post). CV4par was 1.33 ± 0.08 m·s. V[Combining Dot Above]O2, HR, [La], and RPE were similar between first 10-minute and Post time points in the 3 × 10-minute protocol. CV4par was equivalent to 92 ± 2% of the mean swimming speed of T400 (v400) for these swimmers. CV4par calculated through a single T400 (92%v400) showed excellent agreement (r = 0.30; 95% CI: -0.04 to 0.05 m·s, p = 0.39), low coefficient of variation (2%), and root mean square error of 0.02 ± 0.01 m·s when plotted against CV4par assessed through a 4-parameter model. These results generated the equation CV4par = 0.92 × v400. A single T400 can be used reliably to estimate the CV4par typically derived with 6 efforts in age-group swimmers.

    Full Text Available Background and Aim: Falls are the leading cause of accidental death among older adults. Recent studies have demonstrated that an impaired ability to maintain balance while simultaneously performing cognitive tasks is associated with increased rates of adverse outcomes, such as falls in elderly people. Because interventions designed to improve dual-task balance performance have the potential to reduce falling rate and functional decline, they are a critical health care need.Material & Methods: 60 healthy adults in four equal groups (mean age in: young men=22.1±1.9, old men =68.3±4.1, young women =22.6±1.8, old women =66.9±2.6 participated in this study. All subjects experienced four test conditions including: single- task with eyes open (O1, single- task with eyes closed (C1, dual-task with eyes open (O2 and dual-task with eyes closed (C2. Postural task in this study included standing on 8 instability level of biodex balance SD machine plate and cognitive task was backward counting by three.Results: balance index mean in older group was significantly higher in comparison with young group in all test conditions (O1 P=.000, C1 P=.003, O2 P=.000, C2 P=.000. There are not any significant differences between gender groups balance index mean, in test conditions. In Young women group O2 overall (OL, antroposterior (AP and mediolateral (ML balance indexes means were significantly higher than corresponding amounts in C2 (OL P=.014, AP P=.030, ML P=.017. In old women group C2 ML balance index mean was significantly higher than O2 ML balance index mean (P=.034. There are not significant differences between single- and dual-task conditions in other within group comparisons.Conclusion: In young men, young women and old women balance index means are different between single and dual eyes closed condition. Older adults balance index in single- and dual-task conditions is higher than young adults balance index. There is not any difference between men and

    This study determined the carriage rate and serotype distribution of group B Streptococcus (GBS) in women of child-bearing age in the southern region of Ireland. A total of 2000 vaginal swabs collected in two periods in 2004 and 2006 were examined and revealed a GBS carriage rate of 16·1%. Serotyping of isolates showed that serotypes Ia, II, III, IV, and V were the most prevalent. A high prevalence of serotype IV was found, increasing from 7·6% to 15·2% between 2004 and 2006. Random amplified polymorphic DNA analysis demonstrated considerable genetic heterogeneity in the serotype IV isolates. This serotype should be considered for inclusion in potential vaccines for use in Ireland.

To assess the prevalence of domestic violence among the ever married women in reproductive age group and to find out the types of domestic violence and factors associated with it. The study was a community based cross-sectional study, conducted in a slum area of Kolkata. Overall prevalence of domestic violence was 54%, of which 41.9% suffered from both current and lifetime physical and psychological violence. Presence of property, higher per capita income and social support were protective factors against domestic violence, whereas alcohol addiction and multiple sex partners were the important contributory factors for it. The study recommended more social support, awareness and income generation for women in the slum areas.

    Our study, based on microsimulation models, evaluates the redistributive impact of health care insurance in France on income distribution between age and social groups. This work sheds light on the debate concerning the respective role of the public health care insurance (PHI) and the private supplemental health care insurance (SHI) in France. The analysis points out that the PHI enables the lowest-income households and the pensioners a better access to health care than they would have had under a complete private SHI. Due to the progressivity of taxes, low-income households contribute less to the PHI and get higher benefits because of a weaker health. Pensioners have low contributions to public health care finance but the highest health care expenditures.

    Full Text Available Cushing syndrome, a systemic disorder, is the result of abnormally high blood level of cortisol or other glucocorticoids. The most common cause of Cushing syndrome is prolonged exogenous administration of glucocorticoid hormones. Prolonged use of topical corticosteroids, particularly in children, may cause Cushing syndrome and suppression of the hypothalamopituitory-adrenal axis, which is less common than that of oral or parenteral route. However, iatrogenic Cushing syndrome in the infantile age group due to topical steroid is very rare and only a few patients have been reported to date in the literature. Here we report a case of iatrogenic Cushing syndrome due to topical steroid application in a 5-month-old female child admitted to the hospital for repeated episodes of fever and cough.

    Full Text Available Glioneuronal neoplasms are rare tumors. Recently, an unusual glioneuronal tumor histologically showing neuropil-like islands has been described. Here, we present such a tumor originating from spinal cord of a 14-year-old girl, who has scoliosis and urinary incontinence. Microscopically, the glial component was chiefly fibrillary astrocytic, punctuated by neuropil-like islands. Immunohistochemically, glial tissue was GFAP positive, and neuropil-like areas and big neurons were synaptophysin reactive. For astrocytic component Ki-67 proliferation index was 1% and p53 was immunonegative. This case is unique in that in the literature it is the second reported case in pediatric age group that is located at spinal cord.

    The impact of age on the incidence of cerebral vasospasm after aneurysmal subarachnoid hemorrhage (aSAH) is a matter of ongoing discussion. The aim of this study was to identify age groups with a higher risk for developing vasospasm, delayed ischemic neurological deficit (DIND), or delayed infarction (DI) and to identify a cut-off age for a better risk stratification. We defined six age groups (70 years). ROC analysis was performed to determine a cutoff age with the highest positive predictive value (PPV) for developing vasospasm, defined as a blood-flow-velocity-increase >120 cm/s in transcranial-Doppler-sonography (TCD). Multivariate binary-logistic-regression-analysis was then performed to evaluate differences in the incidence of cerebral vasospasm, DIND, and DI among the different age groups. A total of 753 patients were included in the study. The highest incidence (70 %) of TCD-vasospasm was found in patients between 30 and 39 years of age. The cutoff age with the highest PPV (65 %) for developing TCD-vasospasm was 38 years. Multivariate analysis revealed that age <38 years (OR 3.6; CI 95 % 2.1-6.1; p < 0.001) best predicted vasospasm, followed by the need for cerebrospinal fluid drainage (OR 1.5; CI 95 % 1.0-2.3; p = 0.04). However, lower age did not correlate with higher rates of DIND or infarcts. The overall vasospasm-incidence after aSAH is age-dependent and highest in the age group <38 years. Surprisingly, the higher incidence in the younger age group does not translate into a higher rate of DIND/DI. This finding may hint towards age-related biological factors influencing the association between arterial narrowing and cerebral ischemia.

    Full Text Available Radiometric and geochemical studies were carried out at Red Hill in the southern part of King George Island (South Shetland Islands, northern Antarctic Peninsula on the Bransfield Strait coast. The rock succession at Red Hill has been determined to represent the Baranowski Glacier Group that was previously assigned a Late Cretaceous age. Two formations were distinguished within this succession: the lower Llano Point Formation and the upper Zamek Formation. These formations have stratotypes defined further to the north on the western coast of Admiralty Bay. On Red Hill the Llano Point Formation consists of terrestrial lavas and pyroclastic breccia; the Zamek Formation consist predominantly of fine to coarse tuff, pyroclastic breccia, lavas, tuffaceous mud-, silt-, and sandstone, locally conglomeratic. The lower part of the Zamek Formation contains plant detritus (Nothofagus, dicotyledonous, thermophilous ferns and numerous coal seams (vitrinitic composition that confirm the abundance of vegetation on stratovolcanic slopes and surrounding lowlands at that time. Selected basic to intermediate igneous rocks from the succession have been analysed for the whole-rock K-Ar age determination. The obtained results indicate that the Red Hill succession was formed in two stages: (1 from about 51–50 Ma; and (2 46–42 Ma, i.e. during the Early to Middle Eocene. This, in combination with other data obtained from other Baranowski Glacier Group exposures on western coast of Admiralty Bay, confirms the recently defined position of the volcano-clastic succession in the stratigraphic scheme of King George Island. The new stratigraphic position and lithofacies development of the Red Hill succession strongly suggest its correlation with other Eocene formations containing fossil plants and coal seams that commonly occur on King George Island.

    Full Text Available Objectives: To assess the relative position of the mandibular foramen (MF and to evaluate the measurement of gonial angle (GoA and its relationship with distances between different mandibular borders in growing children between 3 and 13years of dental age. Materials and methods: The radiographs were traced to arrive at six linear and two angular measurements from which the relative position of the MF was assessed and compared in different age groups to determine the growth pattern of the mandible and changes in the location of the MF. Results: The distances between the MF and the anterior plane of the ramus were greater than that between MF and posterior plane of the ramus through all stages. There was a maximum increase in the vertical dimensions of the mandible compared with the horizontal dimensions, particularly in the late mixed dentition period. Conclusion: The mandible and its growth did not alter the position of the MF, both vertically and horizontally, in relation to different landmarks, and more obtuse GoA indicated an increased growth potential of the mandible. This has major implications in the inferior alveolar nerve block technique when used in children.

    Eight youngsters (five female, three male, ages 10 to 19 years, mean 15 years) with isolated severe rheumatic mitral regurgitation have been subjected to mitral annuloplasty because of limiting symptoms and prominent ECG and X-ray changes. They have been followed for up to 11 years (mean 3.7 years), and 7 have had excellent results. An early (1961) patient had a small annulus and was not a favorable candidate; he had only transient improvement. Seven are greatly improved, have decreased cardiac size (often dramatic), and have improved ECG's. One has undergone successful pregnancy, and none has been limited in activities. The extent and duration of improvement, lack of mortality, and resumption of normal activities by these youngsters indicate surgical success. The essence of childhood and youth is activity and the future life span hopefully long; hence, annuloplasty would appear to be the procedure of choice for severe rheumatic mitral regurgitation in the pediatric age group, avoiding the usual need for anticoagulation and uncertain long-term results associated with mitral valve replacement.

    Full Text Available ABSTRACT Few studies involving the cognition of middle-aged adults are available in the international literature, particularly investigating the process of cognitive aging, executive components and attention. Objectives: The aim of this study was to investigate whether there are differences in performance on neuropsychological tasks of executive functions and sustained attention between two age groups. Methods: The sample consisted of 87 adults aged from 19 to 59 years old, divided into two groups according to the age variable (younger adults and middle-aged adults. All participants were Brazilian and had no sensory, psychiatric or neurological disorders; subjects also had no history of alcohol abuse, and no self-reported use of illicit drugs or antipsychotics. The neuropsychological instruments administered were the Hayling Test, Trail Making Test, Bells Test and verbal fluency tasks. Results: Groups showed no significant differences in relation to sociodemographic variables, educational level or frequency of reading and writing habits. The younger adult group performed better than the middle-aged group on tasks that involved mainly processing speed, cognitive flexibility and lexical search. Conclusions: These findings serve as a valuable reference for cognitive processing in middle-aged adults, since a large number of comparative studies focus only on the younger and later phases of adulthood. Additional studies are needed to investigate possible interaction between different factors such as age and education.

    Background Reduction in muscle strength is strongly associated with functional decline in women, and women with lower quadriceps strength adjusted for body weight are more likely to develop knee osteoarthritis. Objective To compare body weight--adjusted strength among women of different age/racial groups. Study Design Cross-sectional study of muscle strength in 918 women aged 20--83 (M ± SD = 52 ± 13). Methods An orthopedic examination was conducted including measurement of handgrip and lower extremity strength (hip abductors/external rotators, knee flexors/extensors). Data were grouped into young (20--39 years, n = 139), middle (40--54 years, n = 300), and older (55+ years, n = 424) ages for white (n = 699) and African American (AA) (n = 164) women. Means and standard deviations for strength adjusted for body weight were calculated for each age and racial group and compared using 2-way multivariate analysis of variance and post hoc tests. Results No significant age-by-race interaction (P = .092) but significant main effects for age and race (P < .001). Pairwise comparisons revealed significant differences in knee extensor and flexor strength between all age groups. For grip and hip external rotator strength, significant differences were found between the middle and older groups. Differences in hip abductor strength were found between the young and middle-aged groups. AA women had lower strength than white women in all muscle groups (P < .05) except hip external rotators. Conclusions Strength decreased with age in all muscle groups but magnitude of decrease varied by muscle. Strengthening programs should target different muscles, depending on a woman's age and race.

    Moskovitz, Nicholas A

    2011-01-01

    The group IVA fractionally crystallized iron meteorites display a diverse range of metallographic cooling rates. These have been attributed to their formation in a metallic core, approximately 150 km in radius, that cooled to crystallization in the absence of any appreciable insulating mantle. Here we build upon this formation model by incorporating several new constraints. These include (i) a recent U-Pb radiometric closure age of <2.5 Myr after solar system formation for the group IVA iron Muonionalusta, (ii) new measurements and modeling of highly siderophile element compositions for a suite of IVAs, and (iii) consideration of the thermal effects of heating by the decay of the short-lived radionuclide 60Fe. Our model for the thermal evolution of the IVA core suggests that it was approximately 50 - 110 km in radius after being collisionally exposed. This range is due to uncertainties in the initial abundance of live 60Fe incorporated into the IVA core. Our models define a relationship between cooling rat...

    The Childhood Trauma Questionnaire (CTQ) is internationally accepted as a key tool for the assessment of childhood abuse and neglect experiences. However, there are relative few psychometric studies available and some authors have proposed two different factor solutions. We examined the dimensional structure and internal consistency of the Brazilian version of the CTQ. A total of 1,925 participants from eight different clinical and non-clinical samples including adolescents, adults and elders were considered in this study. First, we performed Confirmatory Factor Analysis to investigate the goodness of fit of the two proposed competitive factor structure models for the CTQ. We also investigated the internal consistency of all factors. Second, multi-group analyses were used to investigate measurement invariance and population heterogeneity across age groups and sex. Our findings revealed that the alternative factor structure as opposed to the original factor structure was the most appropriate model within adolescents and adults Brazilian samples. We provide further evidence for the validity and reliability of the CTQ within the Brazilian samples and report that the alternative model showed an improvement in fit indexes and may be a better alternative over the original model.

    Full Text Available The purpose of this study was to explore the relationship between the intensity of acid reflux and severity of esophageal tissue damage in a cross-sectional study of patients with gastroesophageal reflux disease (GERD. Seventy-eight patients with were selected in accordance with the strict 24-hour ambulatory esophageal pHmetry (24h-pHM criteria and distributed into three age groups: Group A: 14 - 24 years of age. Group B: 25 - 54; and Group C: 55 - 64. The 24h-pHM was carried out in accordance with DeMeester standardization, and the Savary-Miller classification for the diagnosis of reflux esophagitis was used. The groups were similar in 24h-pHM parameters (p > 0.05, having above normal values. For the study group as a whole, there was no correlation between age group and intensity of acid reflux, and there was no correlation between intensity of acid reflux and severity of esophageal tissue damage. However, when the same patients were sub-grouped in accordance with the depth of their epithelial injury and then distributed into age groups, there was a significant difference in esophagitis without epithelial discontinuity. Younger patients had less epithelial damage than older patients. Additionally, although there was a significant progression from the least severe to the moderate stages of epithelial damage among the age groups, there was no apparent difference among the age groups in the distribution between the moderate stages and most severe stages. The findings support the conclusion that the protective response of individuals to acid reflux varies widely. Continued aggression by acid reflux appears to lead to the exhaustion of individual mechanisms of epithelial protection in some patients, but not others, regardless of age or duration of the disease. Therefore, the diagnosis and follow-up of GERD should include both measurements of the quantity of refluxed acid and an assessment of the damage to the esophageal epithelium.

    One of the fundamental problems to understanding the evolution of volcano-sedimentary sequences in southeastern Brazil is constraining their depositional ages. Brasiliano tectonic and metamorphic either obscured or destroyed primary features, such as unconformities, as well as other geologic relationships. This problem is exemplified by the Serra do Itaberaba and Sao Roque groups, where the lack of data about the timing of their deposition has prevented resolution of proposed one-and two-stage geotectonic/depositional models. Recent U-Pb zircon data obtained from metavolcanic rocks in the Sao Roque Group indicate that it was deposited between 628 and 607 Ma. New U-Pb zircon data of 1395{+-} 10 Ma for a metandesite in the basal Morro da Pedra Preta Formation (Serra do Itaberaba Group) indicate the maximum age for the beginning of the deposition of the pelites overlying MORB-like basalt. A metarhyolite of the upper unit, the Nhangucu Formation, contains two zircon populations. One yielded an age of 619 {+-}3 Ma, which defines the crystallization age of the rock, and the other an age of 1449 {+-}3 Ma, interpreted as inherited xenocrystal grains from older units of the Serra do Itaberaba Group. The younger metarhyolite was affected only by the S{sub 2} foliation, generated during the Brasiliano orogenesis, whereas the Middle Proterozoic metavolcano-sedimentary sequence records additional metamorphic and deformational events, confirming the presence of two different geotectonic cycles.

    Full Text Available PURPOSE: Although laparoscopy is considered the mainstay for most renal procedures in adults, its role in the pediatric population is still controversial, especially for smaller children. We reviewed our experience in pediatric renal laparoscopic surgery in three pediatric age groups in an attempt to identify if age has an impact on feasibility and surgical outcomes. MATERIALS AND METHODS: From November 1995 to May 2006, 144 pediatric laparoscopic renal procedures were performed at our institution. The charts of these patients were reviewed for demographic data, urologic pathology and surgical procedure, as well as perioperative complications and post-operative outcomes. The findings were stratified into 3 groups, according to patient age (A: < 1 year, B: 1 to 5 years and C: 6-18 years. RESULTS: Median age of the patients was 4.2 years (42 days - 18 years. We performed 54 nephrectomies, 33 nephroureterectomies, 19 upper pole nephrectomies, 11 radical nephrectomies, 22 pyeloplasties and 4 miscellaneous procedures. The 3 age groups were comparable in terms of the procedures performed. Conversion rates were 0%, 1.4% and 1.9% for groups A, B and C, respectively (p = 0.72. Incidence of perioperative complications was 5%, 8.2% and 7.8% for age groups A to C, respectively (p = 0.88. CONCLUSIONS: Most renal procedures can be performed safely by laparoscopy in the pediatric population, with excellent aesthetic and functional outcomes. The morbidity related to the procedure was minimal irrespective of the age group.

    Nowadays, the age group affected from measles has widened and the disease has become more common among adolescents and young adults. The number of measles case reports have increased in our country, particularly from 2010-2011, and measles outbreaks occurred in various regions in 2012 and 2013. The aim of this study was to analyze the demographical and epidemiological characteristics, clinical and laboratory findings, and complications of adult patients with measles who were affected during the outbreak. A total of 28 patients (25 male, 3 female; age range: 19-39 years, median age: 24) who were hospitalized and followed-up in our clinic between January 2013 and June 2013, were evaluated. In the serum sample of the index case, measles-specific IgM antibodies were detected by ELISA, and measles virus RNA by real-time polymerase chain reaction (RT-PCR), then genotyping was performed to detect the epidemiological relationship. In all of the other cases, measles IgM and IgG antibodies were screened by ELISA. The most common symptoms on admission included high fever (n= 28, 100%), malaise (n= 25, 89%), sore throat (n= 25, 89%), headache (n= 20, 71%) and cough (n= 18, 64%). At physical examination, rash (n= 28, 100%), lymphadenopathy (n= 11, 39%) and conjunctivitis (n= 10, 36%) were in the foreground, and Koplik spots were detected in five (18%) cases. The most common laboratory findings were; increased level of C-reactive protein (n= 15, 54%), leukopenia (n= 12, 43%) and increased serum levels of aminotransferases (n= 12, 43%), and thrombocytopenia was detected in five (18%) patients. One or more complications (secondary bacterial pneumonia in 5, diarrhea in 4, hepatitis in 3 and otitis in 2 cases) developed in the eight (29%) patients. Measles RT-PCR and IgM tests yielded positive results for the index case, and the isolate was identified as D8 strain by genotyping. Measles lgM antibodies were also positive in all of the other cases. The hospitalization period was

    Full Text Available This study has the objective to describe the reasons that take the aged ones to practice physical activities in the Third Age Groups and the barriers that hinder them. Thirty aged citizens were subject of this research. The methodological approaching was an exploratory descriptive study, in witch was applied a questionnaire about motivation and barriers for the physical activity practice. As result, it was evidenced that the motivation of the aged ones for physical activity practice is related to: To congregate and meet with other people; to feel itself carried through; to feel themselves mentally more alert and to improve and keep the health. As for the barriers, they exist, in diverse aspects: social, physical and psychic. Although they exist, for these aged ones it did not became something that completely hindered them to go to the group and to practice physical activities. In conclusion, although the difficulties that the aged ones find day after day, the motivation and the barriers are related to the perception of each one, which can become an important and definitive factor for the assiduity or desistance of these individuals in the third age group.

    A report is presented of SHRIMP zircon U-Pb dating data of meta-igneous and meta-sedimentary rocks of the Xinghuadukou Group (Xinlin-Hanjiayuanzi area, Heilongjiang Province) and meta-volcanic rocks of the Zhalantun Group (Zhalantun district, Inner Mongolia). The SHRIMP analyses show that the meta-igneous rocks from the Xinghuadukou Group formed at 506±10-547±46 Ma, belonging to Early-Middle Precambrian, whereas the meta-sedimentary rocks yielded detrital zircons, with ages of 1.0-1.2, 1.6-1.8 and 2.5-2.6 Ga, indicative of deposition age at least <1.0 Ga.Meta-basic volcanic rocks from the Zhalantun Group have a formation age of 506±3 Ma. These data suggest that both the Xinghuadukou and Zhalantun Groups formed during Cambrian and/or Neoproterozoic time, rather than Paleoproterozoic time as previously thought. Early Precambrian inherited zircons in the meta-igneous rocks and numerous Precambrian detrital zircons in the meta-sedimentary rocks imply that these rocks were formed proximal to older crust. It is inferred that the Xinghuadukou and Zhalantun Groups represent Cambrian and/or Neoproterozoic volcano-sedimentary sequences formed in an active continental margin setting.

    The aim of the study was the validation and adaptation of the ORTO-15 Questionnaire in the group of the Polish schoolgirls and schoolboys. The study included 399 participants (15-21 years old), all of them high school students in the city of Sosnowiec. The ORTO-15 is a tool created in Italy by L.M. Donini, comprising of 15 items describing intensification of orthorexia risk (population diagnosis). The validation procedure incorporated three basic methods to be applied in the reliability analysis - the comparison of double tests with the same method, the statistical properties analysis of test items as well as analysis of the relation of test items with the general test result. Moreover, the compliance of the ORTO-15 Questionnaire results with other questionnaire focused on eating habits (EAT-26) was studied. The reliability analysis of the ORTO-15 Questionnaire based on repeatability of the responses presents a very good (kappa: 0.81 - 1.00 for 5 items) and a good repeatability (kappa: 0.61 - 0.80 for 10 items). The reliability analysis based on the value of the Cronbach's α reached a satisfactory level (0.7 - 0.9). A full agreement of in the occurrence of orthorexia risk and the risk of eating disorders concerned 47.2% (Kappa = 0.04; 95% CI: 0.004 - 0.09) for the Ortho-40 and 88.2% (Kappa = 0.32; 95% CI: 0.17 - 0.47) for the Ortho-35. The ORTO-15 questionnaire is a reliable tool to identify the risk of ON in population studies in the group of urban youth aged 15 - 21.

    AIM: To explore the seropositive rate of antibodies against H. pylori(anti-HP) in Taipei City and to compare the relationship of ABO blood groups and H. pylori infection.METHODS:In 1993, high school students in Shih-Lin District were randomly selected for blood samplings by their registration number at school. In addition, similar procedures were performed on the well-children clinics of Taipei Veterans General Hospital. Besides, randomly selected sera from the adults who took the physical examination were recruited for evaluation. Informed consents were obtained from all the subjects before blood samplings and parents were simultaneously informed for those who were younger than 18-year-old. Blood tests for anti-HP and ABO blood groupings were performed by enzyme-linked immunosorbent assay.Chi square tests were used for the comparisons between seroprevalence of H. pylori and ABO blood groups.RESULTS: Totally, 685 subjects were recruited (260 children aged 1-14 years, 425 high school students aged 15-18 years)were evaluated, and another 88 adult healthy volunteers were studied as well for comparison. The age-specific seropositive rate of anti-HP was 1.3 % at age 1-5 years,7.7 % at age 6-10 years, and 11.5 % at age 11-14 years.The seroprevalence of H. pylori infection was abruptly increased in young adolescence: 18.6 % at age 15 years,28.1% at age 16 years, 32.4 % at age 17 years and 41.0%at age 18 years, respectively. In the 425 high school students,ABO blood groupings were performed, which disclosed 48.5 % (206/425) of blood group O, 24 % (102/425) of blood group A, 21.8 % (93/425) of blood group B and 5.6 %(24/425) of blood group AB. In comparison of the subjects with blood group O and the other blood groups, no statistical significance could be identified in the seroprevalence of H. pylori(P=0.99).CONCLUSION: The seroprevalence of H. pylori infection in Taipei City in adults is similar to the developed countries,and the abrupt increase of H. pylori during high

    BPPV is a common cause of vertigo. Several treatment procedures can facilitate recovery. In this study, we aimed to identify the demographic features, resolution and recurrence rates and impacts on daily activities in BPPV patient between young and senior age groups in Taiwan. This retrospective study recruited 218 patients of BPPV. Medical history, canal involvement, treatment required for complete resolution, symptom free period and recurrence rates were evaluated between the two age groups. Up to 80.7% of patients were successfully treated by a single treatment. For patients aged more than 65 years, the recurrence rate was 1.7 times higher than that in the younger age group (p = 0.07). The symptom-free period before recurrence was nearly 2.2 times longer in the senior age group (p = 0.03). Work-related activities were influenced more by BPPV in the younger age group (p = 0.03). We conclude that BPPV is prone to occur and recur in people of senior age. Clinicians should have the knowledge to diagnose different types of BPPV and treat it accordingly to prevent further complications.

    Full Text Available BACKGROUND Abnormal uterine bleeding is the most common complaint in gynaecology and an important source of morbidity. This study evaluates the usefulness of hysteroscopy in the diagnosis of abnormal uterine bleeding in comparison to dilatation and curettage in reproductive age group. MATERIALS AND METHODS Between September 2011 to July 2013, women with AUB attending Gynaec OP were subjected to hysteroscopy and subsequent dilatation and curettage. Data was collected and analysed. RESULTS AUB was more common in 30-34 yrs. The most common presenting complaint was menorrhagia. Normal hysteroscopic view was seen in 50% cases. Abnormalities seen were endometrial hyperplasia, polyps, submucous myoma synechiae and rue. Both hysteroscopy and curettage gave specificity of 70%, but the ability to diagnose focal lesion (sensitivity was more with hysteroscopy in comparison to curettage 70 vis. 36. 43 patients had the same tissue diagnosis in both hysteroscopy and curettage. Hysteroscopy revealed more information than curettage in 42% and curettage had more information in 15% cases, 100% accuracy was seen in case of myoma, IUCD, adhesions and polyps with hysteroscopy. CONCLUSION This study confirms the conclusion of many others that hysteroscopy is superior to dilatation and curettage in evaluating patients with abnormal uterine bleeding.

    Full Text Available The model of measuring the subjective well-being of a senior age group of population built on a reflective base is proved. The model methodology is based on the theory of needs, daily practices, system and life words of individual existence, and it allows defining measured parameters of subjective well-being recorded by the emotional involvement in main spheres of life. The goal of the paper is to justify the model content and to identify key indicators of the subjective significant indices of senior well-being. The objective of the study is to identify factors influencing the level of the subjective well-being of senior population. The study of the problem involves an explication method and a hermeneutical approach used to clarify the basic concepts of the research. Due to theoretical analysis, it is concluded that the subjective well-being is interpreted as an integral, relatively stable individual emotional response to the impact of the social environment and conditions of his/ her life. It is a result of human understanding and experiencing the meanings and significance of different aspects of human life, evolved from the conditions of human existence, which define the satisfaction degree of his/her needs, life opportunities, self-assertion, self-realization, and actions that are taken to get benefits.

    Full Text Available The aim of this study is to evaluate the materials of gastric biopsies in cases diagnosed as chronic gastritis according to the Sydney system and to compare the parameters according to age groups. The Sydney system of gastritis has five main histological features of changes in gastric mucosa graded (chronic inflammation, neutrophil activity, glandular atrophy, intestinal metaplasia and Helicobacter pylori density In our study, we evaluated 63 patients under 31 years, 177 patients between the ages of 31-60 and 187 patients over 61 years, who were diagnosed as having chronic gastritis by endoscopic biopsy. In 31-60 age group, the localization of Helicobacter pylori was often the antrum. In contrast, in the under 31 years of age group, Helicobacter pylori infection were found to be in the form of the distribution pangastrit. Acute inflammation in the under31 years group was found to be significantly higher than other age groups. In over 61years group, high incidence of atrophy was found. In our study, we detected the rate in atrophy and intestinal metaplasia with Helicobacter pylori is independently increased with age. [J Contemp Med 2012; 2(3.000: 173-178

    Full Text Available Background: Unmet need for family planning signifies the gap between the reproductive intentions of couples and their actual contraceptive behaviour. The National Family Health Surveys carried out in India in 1992-93, 1998-99 and 2004-2005 have revealed that for a sizable proportion of the population in the reproductive age group, the need for contraceptive services are not met with despite the existence of a National Policy on family planning since 1983. This study was carried out to assess the extent of unmet need for family planning among married women of reproductive age group in urban slums of Lucknow and identify the various factors affecting it. Study design: Cross sectional Setting: four urban slums of Lucknow Participants: 414 married women in the age group of 15- 44 years Study variables: age, education, occupation, religion, parity Statistical analysis: chi- square test, logistic regression analysis, fisher’s exact test Results: the extent of unmet need among married women of reproductive age group was 53.1%. The unmet need was found to be significantly associated with age, number of living sons, discussion of family planning with husband, perception of husband’s view on family planning and husbands’ behaviour towards use of family planning method. Logistic regression analysis of unmet need showed that the lower age of the woman, lesser number of living sons and husband’s discouragement towards the use of FP method were correlated with the unmet need for Family Planning.

    2003-08-01

    Much research has examined gender and age effects on compensation, concluding that a wage gap exists favoring men and negative stereotypes against older workers persist. Although the effect of an employee's gender or age has been widely studied, little work has examined the impact of the demographic characteristics of a focal employee's immediate referent groups (e.g., subordinates, peers, or supervisors) on pay. The effect of the gender and age composition of a focal manager's subordinates, peers, and supervisor on the manager's compensation levels was investigated in a sample of 2,178 managers across a wide range of organizations and functional areas. After controlling for a number of human capital variables, results indicated that not only does a wage gap favoring men exist, but also managerial pay is lower when managers' referent groups are largely female, when subordinates are outside the prime age group, and when peers and supervisors are younger.

  15. Phenotypic and functional characterization of lymphocytes from different age groups of Bolivian squirrel monkeys (Saimiri boliviensis boliviensis.

    Directory of Open Access Journals (Sweden)

    Pramod N Nehete

    Full Text Available Due to many physiological and genetic characteristic similarities to humans, squirrel monkeys provide an ideal animal model specifically for studying malaria, and transmissible spongiform encephalopathies (Creutzfeldt-Jacob disease. While squirrel monkeys three years and older are generally considered adult subjects suitable for use in medical research studies, little is known about the functional properties of lymphocytes in relation to the age of these animals, which could significantly impact the quality and quantity of innate and adaptive immune responses. In this study, we investigated differences in the phenotype and function of lymphocytes subsets of young (3-4 years, adult (8-10 years and aged (16-19 years squirrel monkeys. In general, animals in all three age groups exhibited comparable numbers of different lymphocyte subsets except for CD20+ B cells that were significantly lower in aged relative to young animals and T cells subsets expressing both CD4 and CD8 (double positive were significantly higher in aged relative to young animals. With increasing age, phenotypic differences in central and effector memory T cells subsets were observed, that were more pronounced for the CD8+ T cells. Despite equal proportions of CD3+ T cells among the three age groups, responses of peripheral blood mononuclear cells to T cell mitogens PHA and Con A showed lower IFN-γ producing cells in the aged group than that in the young group. Furthermore, aged animals showed significantly higher plasma levels of inflammatory cytokines IL-6, IFN-γ, TNF-α, IL-10 and IL-12. These findings suggest that while the squirrel monkeys in general share phenotypic and functional similarities of lymphocyte subsets with humans in relation to age, specific differences exist in immune function of lymphocytes between young and old animals that could potentially impact experimental outcomes for which the measurement of immunologic endpoints are critical.

    Paleomagnetic inclination and polarity studies were conducted on subcore samples from eight coreholes located at and near the Naval Reactors Facility (NRF), Idaho National Laboratory (INL). These studies were used to characterize and to correlate successive stratigraphic basalt flow groups in each corehole to basalt flow groups with similar paleomagnetic inclinations in adjacent coreholes. Results were used to extend the subsurface geologic framework at the INL previously derived from paleomagnetic data for south INL coreholes. Geologic framework studies are used in conceptual and numerical models of groundwater flow and contaminant transport. Sample handling and demagnetization protocols are described, as well as the paleomagnetic data averaging process. Paleomagnetic inclination comparisons among NRF coreholes show comparable stratigraphic successions of mean inclination values over tens to hundreds of meters of depth. Corehole USGS 133 is more than 5 kilometers from the nearest NRF area corehole, and the mean inclination values of basalt flow groups in that corehole are somewhat less consistent than with NRF area basalt flow groups. Some basalt flow groups in USGS 133 are missing, additional basalt flow groups are present, or the basalt flow groups are at depths different from those of NRF area coreholes. Age experiments on young, low potassium olivine tholeiite basalts may yield inconclusive results; paleomagnetic and stratigraphic data were used to choose the most reasonable ages. Results of age experiments using conventional potassium argon and argon-40/argon-39 protocols indicate that the youngest and uppermost basalt flow group in the NRF area is 303 ± 30 ka and that the oldest and deepest basalt flow group analyzed is 884 ± 53 ka. A south to north line of cross-section drawn through the NRF coreholes shows corehole-to-corehole basalt flow group correlations derived from the paleomagnetic inclination data. From stratigraphic top to bottom, key results

    Computed tomography (CT) is capable of providing accurate and measurable 3-dimensional images of the third molar. The aims of this study were to analyze the development of the mandibular third molar and its relation to chronological age and to create new reference data for a group of Turkish participants aged 9 to 25 years on the basis of cone-beam CT images. All data were obtained from the patients' records including medical, social, and dental anamnesis and cone-beam CT images of 752 patients. Linear regression analysis was performed to obtain regression formulas for dental age calculation with chronological age and to determine the coefficient of determination (r) for each sex. Statistical analysis showed a strong correlation between age and third-molar development for the males (r2 = 0.80) and the females (r2 = 0.78). Computed tomographic images are clinically useful for accurate and reliable estimation of dental ages of children and youth.

    2002-12-01

    This investigation compared and measured for different age groups of students, hours of employment, and previous grading experiences of one student cohort in relation to their perceived overall satisfaction with being graded as a group. A cohort of 230 students from a large southern metropolitan university enrolled in sections of two undergraduate classes. Group Interaction and Decision Making and Conflict Management, participated. Analysis indicated that (a) older students (28-47 years) were more likely to be dissatisfied with a group grade experience than middle (23-27 years) and younger (18-22 years) students. (b) Older students working part time were significantly more dissatisfied with the overall group experience than the younger part-time working students. (c) Older part-time working students were significantly more dissatisfied with the overall experience of working and being graded as a group than the middle part-time and middle full-time working students. Differences were noted between the older and younger students, which supported older students' overall dissatisfaction with their experience of being graded as a group. Common complaints by older students were that younger students were immature, irresponsible, lacked "real-life" experience, and had misplaced priorities. Common complaints by younger students were that older students were too serious and rigid. It is recommended that this work be extended to include other comparison groups, graduate students, and other disciplines.

    Full Text Available Objectives: To explore knowledge and use of drug information resources by pharmacists and identify patterns influenced by gender and age-group classification. Methods: A survey questionnaire was mailed nationwide to 1,000 practitioners working in community (n = 500 and hospital (n = 500 settings who answer drug information questions as part of their expected job responsibilities. Responses pertaining to drug information resource use and knowledge of different types of drug-related queries, resource media preferences, and perceived adequacy of resources maintained in the pharmacy were analyzed by gender and age group. The t statistic was used to test for significant differences of means and percentages between genders and between age groups. Descriptive statistics were used to characterize other findings.Results: Gender and age group classification influenced patterns of knowledge and use of drug information resources by pharmacists. They also affected pharmacists’ perceptions of the most common types of questions prompting them to consult a drug information reference, as well as the resources consulted. Micromedex, exclusively available in electronic format, was the most commonly consulted resource overall by pharmacists. Lexi-Comp Online was the leading choice by women, preferred over Micromedex, but was not one of the top two resources selected by men. Conclusion: This study successfully identified the influence of gender and age-group classification in assessing drug information resource knowledge and use of general and specific types of drug-related queries.

Reasons accounted might be at every level, right from the patient to the physician. In the backdrop of existing disputed treatment strategy operative v/s non-operative treatment of fractures having more than 3-week duration of injury, same were treated by open reduction and k wire fixation using ulnar peg graft. Final functional result was evaluated with longest follow up of over 1 year. Materials and Methods: Twenty children having fracture of lateral condyle of humerus with duration of trauma more than 3 week were included in the prospective study. Age ranged from 5 years to 15 years. Average age was 8 years. Among the 20 patients, 8 were male and 12 were female. Average time of presentation was after 5 weeks of injury. Seven patients had milch type 1 injury and 13 patients had milch type II injury. All patients were treated by open reduction and internal fixation using k wires and ulnar peg graft. The follow-up period was over 1 year. Result: Results were evaluated using radiograph, and functional results were evaluated using the Liverpool elbow scoring system. In the present series, all fractures united with 92% excellent, 5% good, and 3% poor results. Poor results were associated with greater displacement of fracture, prior repeated attempts of close reduction, and history of massage. Conclusion: Being an epiphyseal injury and a common occurrence, fracture of lateral condyle of humerus in pediatric age group are commonly maltreated, with error contributed right from parents to even physician. Common reasons of delayed presentation are ignorance on parents′ side, malpractice by some bone-setters, poorly done radiograph, inaccurate radiographic interpretation by the physician, and poor selection of treatment methods.

    In this article two common approaches to averaging rotations are compared to a more advanced approach based on a Riemannian metric. Very offten the barycenter of the quaternions or matrices that represent the rotations are used as an estimate of the mean. These methods neglect that rotations belong...... approximations to the Riemannian metric, and that the subsequent corrections are inherient in the least squares estimation.

    To determine the prevalence of edentulism in adults aged 18 years and older in Mexico and to describe its distribution in 20 of the 32 States in Mexico, highlighting the experience in the WHO age groups. A secondary analysis of the National Performance Evaluation Survey 2002-2003 (representative at the state level and part of the Word Health Survey) was undertaken. The sample design was probabilistic, stratified and through conglomerates. Data on dental conditions were available only for 20 of the 32 states of Mexico, leading to a total of 24 159 households (N = 54 638 654). The percentage of edentulism was determined as the proportion of subjects that self-reported complete loss of teeth. Data were analyzed using the SVY module for complex surveys in STATA 8.2. The mean age was 41.3 +/- 17.0 years (range 18-99). An estimated 6.3% (N = 3 437 816) of the population > or =18 years was edentulous. Lowest prevalences were observed in the states of Tlaxcala, Puebla and the Estado de Mexico with 3.4%, 3.8% and 4.5%, respectively. Highest prevalences were observed in San Luis Potosí, Colima, and Michoacán with 10.3%, 10.2% and 10.1%, respectively. Following the WHO age groups, the prevalence ranged from 2.4% in the 35-44 group through 25.5% in the 65-74 group. No obvious association between socio-economic and socio-demographic indicators at the state level and prevalence of edentulism was found. The prevalence of complete tooth loss observed in the present study varied greatly across states, although no straightforward association was found with socio-economic and socio-demographic indicators at the state level. This study could serve as a baseline to enable future evaluations of the oral status of Mexican adults and elders, following WHO age groups.

    Full Text Available Abstract Background Raising prices through taxation on tobacco and alcohol products is a common strategy to raise revenues and reduce consumption. However, taxation policies are product specific, focusing either on alcohol or tobacco products. Several studies document interactions between the price of cigarettes and general alcohol use and it is important to know whether increased cigarette prices are associated with varying alcohol drinking patterns among different population groups. To inform policymaking, this study investigates the association of state cigarette prices with smoking, and current, binge, and heavy drinking by age group. Methods The 2001-2006 Behavioral Risk Factor Surveillance System surveys (n = 1,323,758 were pooled and analyzed using multiple regression equations to estimate changes in smoking and drinking pattern response to an increase in cigarette price, among adults aged 18 and older. For each outcome, a multiple linear probability model was estimated which incorporated terms interacting state cigarette price with age group. State and year fixed effects were included to control for potential unobserved state-level characteristics that might influence smoking and drinking. Results Increases in state cigarette prices were associated with increases in current drinking among persons aged 65 and older, and binge and heavy drinking among persons aged 21-29. Reductions in smoking were found among persons aged 30-64, drinking among those aged 18-20, and binge drinking among those aged 65 and older. Conclusions Increases in state cigarette prices may increase or decrease smoking and harmful drinking behaviors differentially by age. Adults aged 21-29 and 65 and older are more prone to increased drinking as a result of increased cigarette prices. Researchers, practitioners, advocates, and policymakers should work together to understand and prepare for these unintended consequences of tobacco taxation policy.

    Although marine fishing is one of the most hazardous occupations, research on the occupational safety and health (OSH) conditions aboard marine fishing vessels is scarce. For instance, little is known about the working conditions of vulnerable groups such as young and aging fishermen. The objective of the current paper is to study the OSH conditions of young and aging fishermen compared to middle-aged fishermen in the small- and medium-size (SM) marine fishing sector. A cross-sectional study was designed, and 686 fishermen working aboard SM fishing vessels were interviewed to collect information about their safety and health. The associations of physical and psychosocial work conditions with safety and health outcomes, e.g., injuries, illnesses and job satisfaction, are presented. The results of the current study can be utilized in the design of effective accident prevention and OSH training programs for the three age groups and in the regulation of working conditions aboard fishing vessels.

    This study compared message-framing effects on physical activity (PA) across age and gender groups. Participants included 111 younger and 100 older adults (68% were women), randomly assigned to read gain-framed or loss-framed PA messages in promotion pamphlets, and who wore accelerometers for the following 14 days. Using regression analyses controlling for demographic and health factors, we found significant age-by-gender-by-framing interactions predicting self-report (B = -4.39, p = .01) and accelerometer-assessed PA (B = -2.44, p = .02) during the follow-up period. Gain-framed messages were more effective than loss-framed messages in promoting PA behaviors only among older men. We speculated that the age-related positivity effect, as well as the age and gender differences in issue involvement, explained the group differences in framing. In addition, more time availability and higher self-efficacy among older men might have contributed to the results.

    To assess the influence of eating breakfast on the consumption of selected food and overweight prevalence among adolescents from different age groups. The study group consisted of students aged 13-18.9 (n=1700). Their height and weight measurements were used to calculate their body mass index and interpreted according to international standards for adolescents. Food consumption was assessed via the frequency method and involved the consumption of breakfast, dietary "bre and sweetened beverages. We used Block's validated questionnaire to assess the intake of dietary "bre and its sources. Analysis of the results was carried out in three age groups: 13-14.9, 15-16.9 and 17-18.9 years old. We used one-factor logistic regression adjusted by gender. The percentage of adolescents with a regular habit of eating breakfast dropped by 5.7 percentage points when compared to adolescents aged 13-14.9 and 17-18.9 (from 54.2% to 48.5%), which was a phenomenon accompanied by an increase in the percentage of adolescents who ate breakfast irregularly or hardly ever (by 3.7 and 1.9 percentage points, respectively). Eating breakfast infrequently was related to a more frequent consumption of sweetened beverages (the odds ratio: from 2.32 to 2.67 depending on the age group) and a higher prevalence of a "bre-poor diet (from 1.49 to 2.23). Among adolescents aged 13-14.9 who hardly ever ate breakfast, the chance of being overweight increased by 83% in comparison to adolescents with regular habits of eating breakfast. The frequency of eating breakfast decreased with the adolescents' age, especially among girls. Eating breakfast infrequently was associated with unhealthy nutrition, typical examples of which are lower intake of dietary "bre and more frequent consumption of sweetened beverages, and in the youngest group of adolescents caused a higher prevalence of overweight.

    Full Text Available Background: Headache or cephalalgia is defined as pain in the head. Headache is an extremely common symptom that may have a profound impact on peoples’ functioning and quality of life. According to International Classification of Headache Disorders (ICHD, they are Primary and Secondary headaches. Primary Headaches are triggered by stress, alcohol, changes in sleep pattern, anxiety, poor posture, all of which are part and parcel our day-to-day life. The study was performed to investigate the prevalence of primary headache disorders and its severity of impact among students and working population in the age group 18-25. Methods: The study was conducted on 718 subjects of which 483 subjects were medical and engineering students from the age group 18-21 and 235 subjects were working people from the age group 22-25. Written consent was taken from each of them. Headache Impact Test-6 (version 1.1 and the HARDSHIP Questionnaire by Timothy Steiner et al. were the questionnaires used to diagnose the severity of impact and the type of headache respectively. The study was ethically approved by Ethical Clearance Board of MAHER University. People suffering from psychiatric illness were excluded from the study. Result: There was increased prevalence of migraine in the age group 18-21 and tension type headache in the age group 22-25.Over 50%of subjects from both the age groups had headaches that have substantial to severe impact on their lives. There was no significant gender variation in headache prevalence.

    To establish causality between flood basalt eruptions and extinction events and global environmental effects recorded by isotopic excursions in marine sediments, highly accurate and precise ages for the flood basalts are required. But flood basalts are intrinsically difficult to date. We illustrate how 40Ar/39Ar feldspar ages for silicic tuffs intercalated with and overlying sections of Steens Basalt, the earliest lavas of the Middle Miocene Columbia River Basalt Group in the northwestern United States, provide high-precision ages that, for the first time, make it possible to resolve age differences with stratigraphic position within a section of these flood lavas. The stratigraphically lowest rhyolitic tuff, a fall deposit, yielded an age of 16.592 ± ± 0.028 Ma (FCs = 28.02 Ma), and the uppermost, the alkali rhyolite ignimbrite Tuff of Oregon Canyon, is 16.468 ± ± 0.014 Ma. The argon and stratigraphic data indicate that Steens Basalt eruptions occurred from ∼16.64 to 16.43 Ma in the southern end of its distribution. We estimate that the Steens Mountain geomagnetic reversal occurred at 16.496 ± ± 0.028 Ma (±0.18 Ma total error). Our estimates of the timing for initiation of volcanism and volumetric eruptive rates do not seem to support volcanic forcing by the initial stages of Columbia River Basalt Group eruptions as an explanation for the abrupt warming and carbonate dissolution at the beginning of the Miocene Climatic Optimum.

    To evaluate differences anatomical location and age groups on CT and clinical data in deep neck abscess. This study included 200 patients who underwent CT and were diagnosed with a deep neck abscess, from December 2005 to July 2010. Patients were divided into four groups by age (children, adolescent, adult, elderly). Next, the anatomic location, location multiplicity and clinical data regarding the deep neck abscesses were analyzed retrospectively. The deep neck abscesses observed were defined as superficial or deep and partitioned into sub-groups, with further analysis of their clinical data. The incidence of the parapharyngeal abscess was more frequent in children and elderly groups (p < 0.05). The masticator abscess was only observed among patients in the elderly group (p < 0.05). Multiple locations were observed with increased frequency in children and elderly groups (p < 0.05). Swelling in the neck was more frequently observed in children and elderly groups (p < 0.05), cervical lymphadenitis was frequently seen in children and adolescent groups (p < 0.05), and the incidence of symptoms including sore throat were significantly increased in adolescent and adult groups (p < 0.05). Location multiplicity was significantly higher in parapharyngeal, retropharyngeal, submandibular, danger, visceral and masticator spaces than other spaces (p < 0.05). With regards to anatomic location, neck swelling was more frequent in superficial group and sore throat was more frequent in deep group (p < 0.05). Deep neck abscess would show significant differences with regards to the abscess location, location multiplicity, and clinical symptoms according to age. The clinical symptoms observed are dependent on the anatomic location as defined by a superficial or deep abscess.

    Full Text Available Proposed modification of group selection system is aimed to successfully combine its elements with biological peculiarities (such as sympodial growth, distinct heliotropism and crown growth plasticity, heavy seeds and difficult dissemination, etc. of shade-intolerant and mid-tolerant tree species, stands of which may be managed under the same system. Principles, on which the modification is based, are: (i application of well founded extended rotations in order to increase the proportion of tree groups above 90-100 years age in the stand, where upon the height increment and crown side spread by most of the main tree species in Bulgary drop to considerably lower level, and (ii optimum systematic spatial positioning of openings in the stand canopy (and tree groups respectively over the stand area, so that new gaps created by consecutive selection cuttings adjoin to a minimum number of middle aged (40-80 y. age tree groups. Such clumps of vigorous trees with high growth rates, heliotropism and plasticity carry certain risks of spoiling the target regular-unevenaged stand structure. Factors of significance are discussed by determining the rotation age, size of gaps opened in the stand canopy, selection cutting cycle, a regularuneven- aged stand structure design and the minimum area that enables realisation of full selection system cycle. Definitions and determination of selection system elements in their mutual connections are presented in consecutive steps when designing a particular application of group selection system for exemplary pure stand of common beech (Fagus sylvatica L.. By the proposed group selection system modification the amount of combinations of various factors having impact upon processes in the tree groups are diminished compared to that by random spatial arrangement of the gaps over the stand area. Silvicultural activities aimed to maintain a stable unevenaged stand structures are thus getting more predictable, easier to schedule

    Morphometric parameters of neuronal metabolic activity, such as the area of neuronal nuclei and perikarya and nuclear-cytoplasmic ratio, in the nucleus basalis of Meynert (NBM), tuberomamillary (TMN) and medial mammillary (MMN) hypothalamic nuclei of human subjects belonging to four age groups were studied. Statistically significant increase in the size of neuronal perikarya and their nuclei was found in elderly people aged 60-74 years. The surge in the metabolic activity of neurons in the NBM starts earlier than in the TMN and MMN, and becomes apparent morphologically in people of middle age (45-59 years). The age-related increase in the metabolic activity of neurons in the studied structures of the human brain participating in the regulation of memory and other cognitive functions, may represent protective, adaptive and/or compensatory mechanisms of the aging process that also prevents the development of Alzheimer's disease.

The transverse sections of one-third of each part of uterine tube from 116 women (from newborn to senile age were studied. The sections were colored by gematoksilin-eosin, by van Gizon, by Brashe, azur-2-eosine, by Qrimelius. The amount of lymphoid cells of diffuse lymphoid tissue of uterine tube increased till the age of 16-20 and remained at high level further on till the age of 35. The quantity of lymphoid cells of diffuse lymphoid tissue of uterine tube changed according to the age and localization throughout the organ. The presence of diffused lymphoid tissue of uterine tube depended on the state of reproductive function of female organism. In the phase of desquamation there was minimal quantity of lymphoid tissue and in the phase of secretion there was maximal quantity of lymphoid tissue

    以北京市某中学和某小学11~14岁之间294名学生为被试,其中超常儿童131人,普通儿童163人。采用推箱子任务,结合横断比较和纵向追踪数据,从认知能力、元认知能力和认知效率三个维度来考察超常儿童与普通儿童问题解决能力的发展差异。结果发现超常儿童在问题解决能力的三个维度上均优于普通儿童,两类儿童问题解决能力的发展模式不一致:超常儿童的问题解决能力发展先快后慢,快速发展期在11~12岁半之间;普通儿童的问题解决能力发展先慢后快,快速发展期在12岁半~14岁之间。超常儿童与普通儿童的问题解决能力差异随年龄增大逐渐减小。%Problems are everywhere in daily life. The ability to solve problems helps human being survive natural selection, characterizing us as an intellectual species. It is also closely related to various life outcomes. A number of cross-sectional studies have demonstrated that intellectually-gifted children performed better than their average cohorts in problem solving tasks. But most of these studies primarily focus on the cognitive dimension of problem solving. They did not suffice to draw a whole picture of human problem solving ability. Moreover, few studies have explored the group differences from a developmental perspective, such as their developmental patterns or developmental critical stage, which could contribute a lot to both theories and educational practices. The present study investigated the developmental differences of problem solving ability between intellectually-gifted and intellectually-average children from cognitive, metacognitive and efficiency dimensions. Both cross-sectional and longitudinal data were collected. The cross-sectional study included 131 intellectually-gifted and 163 intellectually-average children aged from 11 to14, and the longitudinal study included 32 intellectually-gifted and 38 intellectually-average children

    After an extensive vaccination policy, Japanese encephalitis (JE) was nearly eliminated since the mid-1980s in South Korea. Vaccination in children shifted the affected age of JE patients from children to adults. However, an abrupt increase in JE cases occurred in 2010, and this trend has continued. The present study aimed to investigate the prevalence of neutralizing antibodies to the JE virus (JEV) among high-risk age groups (≥40 years) in South Korea. A plaque reduction neutralization test was conducted to evaluate the prevalence of neutralizing antibodies to JEV in 945 subjects within four age groups (30–39, 40–49, 50–59, and 60–69 years) in 10 provinces. Of the 945 enrolled subjects, 927 (98.1%) exhibited antibodies against JEV. No significant differences were found in the prevalence of neutralizing antibodies according to sex, age, or occupation. However, there were significant differences in the plaque reduction rate according to age and occupation; oldest age group had a higher reduction rate, and subjects who were employed in agriculture or forestry also had a higher value than the other occupations. We also found that three provinces (Gangwon, Jeonnam, and Gyeongnam) had a relatively lower plaque reduction rate than the other locations. In addition, enzyme-linked immunosorbent assays were conducted to determine recent viral infections and 12 (2.2%) subjects were found to have been recently infected by the virus. In conclusion, the present study clearly indicated that the prevalence of neutralizing antibodies has been maintained at very high levels among adult age groups owing to vaccination or natural infections, or both. In the future, serosurveillance should be conducted periodically using more representative samples to better understand the population-level immunity to JE in South Korea. PMID:26807709

    Full Text Available Ewing’s sarcoma is a highly malignant, round cell neoplasm of uncertain origin. It is the sixth most common malignant tumour of bone. It must be distinguished from chronic osteomyelitis and other malignant round cell tumours like lymphoma, metastatic neuroblastoma and small cell osteosarcoma. Most patients are between 10 to 25years old; rarely, patients are younger than age 5 years and older than age 40 years. We report a 55 years female who presented with swelling over right shoulder with pain and inability to move right shoulder later diagnosed as Ewing’s sarcoma of proximal part of humerus right side. The earlier diagnosis at this age may help in better management of the condition and prevent further complications and have a better prognosis.

    Full Text Available The Nanhua basin in South China hosts well-preserved middle–late Neoproterozoic sedimentary and volcanic rocks that are critical for studying the basin evolution, the breakup of the supercontinent Rodinia, the nature and dynamics of the “snowball” Earth and diversification of metazoans. Establishing a stratigraphic framework is crucial for better understanding the interactions between tectonic, paleoclimatic and biotic events recorded in the Nanhua basin, but existing stratigraphic correlations remain debated, particularly for pre-Ediacaran strata. Here we report new Laser Ablation Inductively Coupled Plasma Mass Spectrometry (LA-ICPMS U-Pb zircon ages from the middle and topmost Wuqiangxi Formation (the upper stratigraphic unit of the Banxi Group in Siduping, Hunan Province, South China. Two samples show similar age distribution, with two major peaks at ca. 820 Ma and 780 Ma and one minor peak at ca. 910 Ma, suggesting that the Wuqiangxi sandstone was mainly sourced from Neoproterozoic rocks. Two major age peaks correspond to two phases of magmatic events associated with the rifting of the Nanhua basin, and the minor peak at ca. 910 Ma may correspond to the Shuangxiwu volcanic arc magmatism, which represents pre-collision/amalgamation subduction on the southeastern margin of the Yangtze Block. The youngest zircon group from the topmost Wuqiangxi Formation has a weighted mean age of 714.6 ± 5.2 Ma, which is likely close to the depositional age of the uppermost Banxi Group. This age, along with the ages reported from other sections, constrains that the Banxi Group was deposited between ca. 820 Ma and ca. 715 Ma. The age of 714.6 ± 5.2 Ma from the top of the Wuqiangxi Formation is indistinguishable with the SIMS U-Pb age of 715.9 ± 2.8 Ma from the upper Gongdong Formation in the Sibao village section of northern Guangxi, South China. It is also, within uncertainties, overlapped with two TIMS U-Pb ages from pre

    Autoregulation of blood flow is a key feature of the human cerebral vascular system to assure adequate oxygenation and metabolism of the brain under changing physiological conditions. The impact of advanced age and anesthesia on cerebral autoregulation remains unclear. The primary objective of this study was to determine the effect of sevoflurane anesthesia on cerebral autoregulation in two different age groups. This is a follow-up analysis of data acquired in a prospective observational cohort study. One hundred thirty-three patients aged 18-40 and ≥65 years scheduled for major noncardiac surgery under general anesthesia were included. Cerebral autoregulation indices, limits, and ranges were compared in young and elderly patient groups. Forty-nine patients (37 %) aged 18-40 years and 84 patients (63 %) aged ≥65 years were included in the study. Age-adjusted minimum alveolar concentrations of sevoflurane were 0.89 ± 0.07 in young and 0.99 ± 0.14 in older subjects (P blood pressure range of 13.8 ± 9.8 mmHg in young and 10.2 ± 8.6 mmHg in older patients (P = 0.079). The lower limit of autoregulation was 66 ± 12 mmHg and 73 ± 14 mmHg in young and older patients, respectively (P = 0.075). The association between sevoflurane concentrations and autoregulatory capacity was similar in both age groups. Our data suggests that the autoregulatory plateau is shortened in both young and older patients under sevoflurane anesthesia with approximately 1 MAC. Lower and upper limits of cerebral blood flow autoregulation, as well as the autoregulatory range, are not influenced by the age of anesthetized patients.

    Full Text Available Functional MRI measured with blood oxygen dependent (BOLD contrast in the absence of intermittent tasks reflects spontaneous activity of so called resting state networks (RSN of the brain. Group level independent component analysis (ICA of BOLD data can separate the human brain cortex into 42 independent RSNs. In this study we evaluated age related effects from primary motor and sensory, and, higher level control RSNs. 168 healthy subjects were scanned and divided into three groups: 55 adolescents (ADO, 13.2 ± 2.4 yrs, 59 young adults (YA, 22.2 ± 0.6yrs , and 54 older adults (OA, 42.7 ± 0.5 yrs, all with normal IQ. High model order group probabilistic ICA components (70 were calculated and dual regression analysis was used to compare 21 RSN’s spatial differences between groups. The power spectra were derived from individual ICA mixing matrix time series of the group analyses for frequency domain analysis. We show that primary sensory and motor networks tend to alter more in younger age groups, whereas associative and higher level cognitive networks consolidate and re-arrange until older adulthood. The change has a common trend: both spatial extent and the low frequency power of the RSN’s reduce with increasing age. We interpret these result as a sign of normal pruning via focusing of activity to less distributed local hubs.

    Dysphagia is a common problem that has the potential to result in severe complications such as malnutrition and aspiration pneumonia. Based on the complexity of swallowing, there may be many different causes. This article presents a systematic literature review to assess different comorbid disease associations with dysphagia based on age. The causes of dysphagia are different depending on age, affecting between 1.7% and 11.3% of the general population. Dysphagia can be a symptom representing disorders pertinent to any specialty of medicine. This review can be used to aid in the diagnosis of patients presenting with the complaint of dysphagia.

  19. Cost and Impact of Voluntary Medical Male Circumcision in South Africa: Focusing the Program on Specific Age Groups and Provinces.

    Directory of Open Access Journals (Sweden)

    Katharine Kripke

    Full Text Available In 2012, South Africa set a goal of circumcising 4.3 million men ages 15-49 by 2016. By the end of March 2014, 1.9 million men had received voluntary medical male circumcision (VMMC. In an effort to accelerate progress, South Africa undertook a modeling exercise to determine whether circumcising specific client age groups or geographic locations would be particularly impactful or cost-effective. Results will inform South Africa's efforts to develop a national strategy and operational plan for VMMC.The study team populated the Decision Makers' Program Planning Tool, Version 2.0 (DMPPT 2.0 with HIV incidence projections from the Spectrum/AIDS Impact Module (AIM, as well as national and provincial population and HIV prevalence estimates. We derived baseline circumcision rates from the 2012 South African National HIV Prevalence, Incidence and Behaviour Survey. The model showed that circumcising men ages 20-34 offers the most immediate impact on HIV incidence and requires the fewest circumcisions per HIV infection averted. The greatest impact over a 15-year period is achieved by circumcising men ages 15-24. When the model assumes a unit cost increase with client age, men ages 15-29 emerge as the most cost-effective group. When we assume a constant cost for all ages, the most cost-effective age range is 15-34 years. Geographically, the program is cost saving in all provinces; differences in the VMMC program's cost-effectiveness across provinces were obscured by uncertainty in HIV incidence projections.The VMMC program's impact and cost-effectiveness vary by age-targeting strategy. A strategy focusing on men ages 15-34 will maximize program benefits. However, because clients older than 25 access VMMC services at low rates, South Africa could consider promoting demand among men ages 25-34, without denying services to those in other age groups. Uncertainty in the provincial estimates makes them insufficient to support geographic targeting.

    The aging process is associated with gradual and progressive loss of muscle mass along with lowered strength and physical endurance. This condition, sarcopenia, has been widely observed with aging in sedentary adults. Regular aerobic and resistance exercise programs have been shown to counteract most aspects of sarcopenia. In addition, good nutrition, especially adequate protein and energy intake, can help limit and treat age-related declines in muscle mass, strength, and functional abilities. Protein nutrition in combination with exercise is considered optimal for maintaining muscle function. With the goal of providing recommendations for health care professionals to help older adults sustain muscle strength and function into older age, the European Society for Clinical Nutrition and Metabolism (ESPEN) hosted a Workshop on Protein Requirements in the Elderly, held in Dubrovnik on November 24 and 25, 2013. Based on the evidence presented and discussed, the following recommendations are made: (1) for healthy older people, the diet should provide at least 1.0 to 1.2 g protein/kg body weight/day (2) for older people who are malnourished or at risk of malnutrition because they have acute or chronic illness, the diet should provide 1.2 to 1.5 g protein/kg body weight/day, with even higher intake for individuals with severe illness or injury, and (3) daily physical activity or exercise (resistance training, aerobic exercise) should be undertaken by all older people, for as long as possible.

    To evaluate, by means of histomorphometry, terminal vertebral plate thickness, intervertebral disc thickness and its correlation on different age groups, seeking to identify its correlation. Methods: C4-C5 and C5-C6 cervical segments removed from human cadavers of both genders were assessed and divided into five groups of 10-year age intervals, from 21 years old. TVP and intervertebral disc thickness evaluation was made by means of histomorphometry of histological slides stained with hematoxylin and eosyn. Lower C4 TVP, upper C5 TVP, and upper C6 TVP de were compared between each other and to the interposed intervertebral disc thickness between relevant TVP. Results: The thickness of terminal vertebral plates adjacent to the same ID did not show statistic differences. However, the comparison of upper and lower vertebral plates thickness on the same cervical vertebra (C5), showed statistical difference on all age groups studied. We found a statistical correlation coefficient above 80% between terminal vertebral plate and adjacent intervertebral disc, with a proportional thickness reduction of both structures on the different cervical levels studied, and also on the different age groups assessed. Conclusion: Terminal vertebral plate shows a morphologic correlation with the intervertebral disc next to it, and does not show correlation with the terminal vertebral plate on the same vertebra.

    A sudden unexpected death is considered one type of medico-legal death in Thailand. In some studies, it comprises up to 50-60% of all medico-legal deaths. In this retrospective study, data were collected from 1,460 cases of sudden unexpected deaths, 39.9% of all deaths in which a medico-legal autopsy had been carried out. The study was conducted over a 5-year period from January 2003 to December 2007. There were 1,009 males and 451 females (M:F ratio = 2.2:1). The mean age was 55.3+/-0.98 years. The peak age group was the 46-60 years accounting for 28.2% of cases. The most common cause of death in all age groups was coronary atherosclerosis. Understanding epidemiological autopsy data is vital for determining the characteristics of the population involved.

    Roe, M and Malone, S. Yo-Yo intermittent recovery test performance in subelite Gaelic football players from under thirteen to senior age groups. J Strength Cond Res 30 (11): 3187-3193, 2016-Gaelic football is indigenous to Ireland and has similar locomotion profiles to soccer and Australian Football. Given the increasing attention on long-term player development, investigations on age-related variation in Yo-Yo intermittent recovery test level 1 (Yo-YoIR1) performance may provide useful information in talent identification, program design, and player monitoring. Therefore, the aim of this study was to evaluate Yo-YoIR1 performance across Gaelic football age groups. Male participants (n = 355) were recruited from division one, Gaelic football teams. Participants were allocated to one of the 7 groups according to respective age groups from under 13 (U13), under 14, under 15 (U15), under 16 (U16), minor, under 21 (U21), to senior age groups. Total Yo-YoIR1 distance (m) increased progressively from U13 (885 ± 347 m) to U16 (1,595 ± 380 m) equating to a rate of change of 180.2%. In comparison to U13, total distance at minor (1,206 ± 327 m) increased by 136.4%. Subsequent increases were observed in U21 (1,585 ± 445 m) and senior players (2,365 ± 489). Minimum (800-880 m) and maximum (2,240-2,280 m) total distances were comparable for U15, U16, and U21 players. Differences in total distance (m) for all age groups were statistically significant when compared to U13 players (p 0.8). Similar trends were observed for maximum velocity and estimated V[Combining Dot Above]O2max. The evolution of Yo-YoIR1 performance in Gaelic football players from adolescents to adulthood highlights how maturation may influence sport-related running ability. Changes in Yo-YoIR1 performance should be closely monitored to optimize interventions for individuals transitioning across age groups.

    We present a new class of statistical error reduction techniques for Monte-Carlo simulations. Using covariant symmetries, we show that correlation functions can be constructed from inexpensive approximations without introducing any systematic bias in the final result. We introduce a new class of covariant approximation averaging techniques, known as all-mode averaging (AMA), in which the approximation takes account of contributions of all eigenmodes through the inverse of the Dirac operator computed from the conjugate gradient method with a relaxed stopping condition. In this paper we compare the performance and computational cost of our new method with traditional methods using correlation functions and masses of the pion, nucleon, and vector meson in $N_f=2+1$ lattice QCD using domain-wall fermions. This comparison indicates that AMA significantly reduces statistical errors in Monte-Carlo calculations over conventional methods for the same cost.

    The distribution of periodontal disease stages is not the same in both human jaws, parts of the same jaw or in different ages of life. In the sample of 2,730 sextants, 455 persons 15+ years of age, analysis of distribution of both periodontal disease and loss of attachment in jaw sextants in different age groups was made, using the Community Periodontal Index (CPI) and Loss of Attachment (LA). Statistical significance testing was checked using the Pearson Chi-Square-test with probability of 95%. Healthy periodontium is mostly found in upper anterior sextant (36%, p calculus in lower anterior sextant (48.19%, p or = 12 mm appears in only 1.4% present sextants and it is rear on left jaw side. Significant differences in distribution of both periodontal disease and loss of attachment appear in age 30+.

    Full Text Available This study evaluated the psychometric properties of an on-line version of the Zuckerman-Kuhlman-Aluja Personality Questionnaire (ZKA-PQ by sex and age. The questionnaire was responded by 1598 people, 474 males and 1124 females, with a mean age of 32.57 (SD = 11.72. Males and females differed in their responses to all personality dimensions evaluated by this instrument, in a similar way as that reported in past research. In addition, younger people scored higher in the Aggressiveness factor, especially concerning the Physical Aggression facet, whereas older people scored higher in the Activity factor. Besides, younger people scored higher in the Neuroticism and the Sensation Seeking factors, even though there were no age differences in the Extraversion factor. The ZKA-PQ five-factor structure was clear and yielded high congruence coefficients with the original Spanish validation sample. Altogether, the findings support the validity of the online version of this instrument. The ZKAPQ online version is therefore helpful in both, basic and applied research settings about human personality and individual differences.

    The aim of the study was identification of statistically reliable correlations and the cause-effect relationships between viability of red blood cells and dislipidema parametres and/or metabolic disorders, induced by age related alterations of estrogen content, in women of different ages (reproductive, menopausal) On the basis of the analysis of research results we can conclude that in the different age groups of women with atherosclerosis-induced cardiovascular diseases revealed estrogen-related dependence between Tg-s and HDL content, functional status of phereperial blood erytrotcites and severity of dislipidemia. The aterogenic index Tg/HD proved to be sensitive marker of dislipidemia in reproductive aging women, but does't reflect disorders of lipid metabolism in postmenosal women. It was proved the existence of reliable corelation between red blood cells dysfunction indicator, spherulation quality, and atherogenic index Tg/HDL highlights; however, the correlation coefficient is 2 times higher in the reproductive age as in menopause. Spherulation quality of red blood cells at low HDL content showd fast growth rate in reproductive-aged women, and was unsensetive to HDL content in postmenopasal women. It was concluded that age-related lack of estrogens in postmenopausal women indirectly contributes to decrease protection of red blood cells against oxidative damage, reduces their deformabelity and disturbances the rheological properties. So, Spherulation quality of red blood cells may be used as a diagnostic marker of severity of atherosclerosis.

Methods: Participation and performance trends in athletes by age group in the Badwater (217 km and Spartathlon (246 km races were compared from 2000 to 2012. Results: The number of female and male finishers increased in both races across years (P 0.05. In Spartathlon, the age of the annual five fastest finishers was unchanged at 39.7 ± 2.4 years for men and 44.6 ± 3.2 years for women (P > 0.05. In Badwater, running speed increased in men from 7.9 ± 0.7 km/hour to 8.7 ± 0.6 km/hour (r2 = 0.51, P 0.05. In Badwater, the number of men in age groups 30–34 years (r2 = 0.37, P = 0.03 and 40–44 years (r2 = 0.75, P < 0.01 increased.

Men in age groups 30–34 (r2 = 0.64, P < 0.01, 35–39 (r2 = 0.33, P = 0.04, 40–44 (r2 = 0.34, P = 0.04, and 55–59 years (r2 = 0.40, P = 0.02 improved running speed in Badwater. In Spartathlon, no change in running speed was observed. Conclusion: The fastest finishers in ultramarathons more than 200 km in distance were 40–45 years old and have to be classified as “master runners” by definition. In contrast to reports of marathoners and ultramarathoners competing in races of 161 km in distance, the increase in participation and the improvement in performance by age group were less pronounced in ultramarathoners competing in races of more than 200 km.

    To determine, for two different age groups, the effect of duration of sevoflurane administration on the amount of propofol needed when performing tracheal intubation. Classic Dixon's Up-and-Down sequential method. University based operating rooms. 106 ASA physical status 1 and 2 patients aged one to 11 years. Patients were allocated to the 1-6 year (≥ 12 and propofol was promptly administered. Propofol dose was determined according to age group and whether propofol was given 2-4, 4-6, or 6-8 minutes after the start of sevoflurane induction, with Dixon's Up and Down Method used separately for each specific age/time group. Tracheal intubation conditions one minute after propofol were evaluated. Isotonic regression determined propofol ED50 estimates for excellent tracheal intubation conditions, and linear regression determined the effect of propofol dose on change in systolic blood pressure (SBP). Estimated propofol ED50 doses for 1-6 year olds, with 95% confidence intervals (CIs), were 1.48 mg/kg (0.80, 2.03), 0.00 mg/kg (0.00, 0.38), and 0.07 mg/kg (0.00, 0.68) in the 2-4, 4-6, and 6-8 minute groups, respectively, with estimated differences between the 2-4 minute group versus the 4-6 and 6-8 minute groups being 1.47 mg/kg (95% CI = 1.04, 2.06) and 1.41 mg/kg (95% CI = 0.74, 2.04), respectively. Estimated propofol ED50 doses for 6-11 year olds, with 95% CIs, were 2.35 mg/kg (1.97, 2.45) and 2.33 mg/kg (1.59, 2.45) in the 2-4 and 4-6 minute groups, respectively. Diminutions in SBP at one minute and two minutes after propofol administration were dose dependent for children 1-6 years of age, decreasing 5.3% and 8.1% for each 1 mg/kg of propofol, respectively. The amount of propofol needed to supplement sevoflurane in children 1-6 years of age can be expected to decrease after 4 minutes of sevoflurane. Copyright © 2014 Elsevier Inc. All rights reserved.

    Full Text Available Background: Paediatric head injury (HI is the single most common cause of death and permanent disability in children world over, and this is increasingly becoming worrisome in our society because of increased risks and proneness to road traffic accidents on our highways and streets. The study set to determine causes and management of HI among children in our society. Patients and Methods: A retrospective review of all children aged 0-15 years with traumatic head injury (THIs who were managed at the University of Maiduguri Teaching Hospital between July, 2006 and August, 2008. Results: A total of 45 children with THIs presented to the casualty unit of the hospital; 30 (66.7% were boys and 15 (33.3% were girls. Three (6.7% children were less than 1 year of age, 21 (46.7% were between 1 years and 6 years while 16 (35.6% and 5 (11.0% were aged 7-11 years and 12-15 years respectively. Thirty six (80.0% of the children were pedestrians, 6 (13.4% fell from a height, while 2 (4.4% and 1 (2.2% were as a result of home accident and assault, respectively. Twenty one patients (46.7% had mild HI, while 53.3% had moderate to severe category. Forty one (91.1% of children were managed as in-patients, mostly (95.1% by conservative non-operative management, while 4 (8.9% were treated on the out-patient basis. The mortality rate was 17.8%. Conclusion: H1 among children is of a great concern, because of its incremental magnitude, due to increasing child labour and interstate religious discipleship among children, with attendant high mortality and permanent disabilities. Necessary laws and legislations should be formulated and implemented with organized campaigns and public enlightenment to prevent and mitigate this menace.

    2015-01-01

    The goal of this pilot study was to ascertain the effectiveness of an occupation-based after-school program for improving self-concept in children, ages five through eight. Fifty-four randomly selected children ages five through eight from two schools (one being the control group) with similar socioeconomic status along the Ohio River were involved in this research study. The Pictorial Scale of Perceived Competence and Social Acceptance for Young Children (PCSA; Harter & Pike, 1984) was administered to all participants (N = 54), four subtests were analyzed: cognitive competence, social competence with peers, physical competence in sports, and maternal acceptance. The experimental group (n = 25) attended occupation-based groups two times a week after school. The control group (n = 29) did not participate in an after-school program. Data from pre-test and post-test were analyzed using a t-test. Findings demonstrated that the experimental group improved their self-concept scores when compared to the control group in the areas of peer acceptance and cognitive competence. This would offer tentative evidence that an after-school program directed by occupational therapists that is designed to improve self-concept may be successful.

Principles, on which the modification is based, are: (i application of well founded extended rotations in order to increase the proportion of tree groups above 90-100 years age in the stand, where upon the height increment and crown side spread by most of the main tree species in Bulgary drop to considerably lower level, and (ii optimum systematic spatial positioning of openings in the stand canopy (and tree groups respectively over the stand area, so that new gaps createdby consecutive selection cuttings adjoin to a minimum number of middle aged (40-80 y. age tree groups. Such clumps of vigorous trees with high growth rates, heliotropism and plasticity carry certain risks of spoiling the target regular-unevenaged stand structure. Factors of significance are discussed by determining the rotationage, size of gaps opened in the stand canopy, selection cutting cycle, a regular uneveaged stand structure design and the minimum area that enables realisation of full selection system cycle. Definitions and determination of selection system elementsin their mutual connections are presented in consecutive steps when designing a particular application of group selection system for exemplary pure stand of common beech (Fagus sylvatica L.. By the proposed group selection system modification the amount of combinations of various factors having impact upon processes inthe tree groups are diminished compared to that by random spatial arrangement of the gaps over the stand area. Silvicultural activities aimed to maintain a stable unevenaged stand structures are thus getting more predictable, easier to schedule and

    Full Text Available Abstract Background Knowledge of the epidemiology of injuries in children is essential for the planning, implementation and evaluation of preventive measures but recent epidemiological information on injuries in children both in general and by age-group in Scotland is scarce. This study examines the recent pattern of childhood mortality from injury by age-group in Scotland and considers its implications for prevention. Methods Routine mortality data for the period 2002–2006 were obtained from the General Register Office for Scotland and were analysed in terms of number of deaths, mean annual mortality rates per 100,000 population, leading causes of death, and causes of injury death. Mid-year population estimates were used as the denominator. Chi-square tests were used to determine statistical significance. Results 186 children aged 0–14 died from an injury in Scotland during 2002–06 (MR 4.3 per 100,000. Injuries were the leading cause of death in 1–14, 5–9 and 10–14 year-olds (causing 25%, 29% and 32% of all deaths respectively. The leading individual causes of injury death (0–14 years were pedestrian and non-pedestrian road-traffic injuries and assault/homicide but there was variation by age-group. Assault/homicide, fire and suffocation caused most injury deaths in young children; road-traffic injuries in older ones. Collectively, intentional injuries were a bigger threat to the lives of under-15s than any single cause of unintentional injury. The mortality rate from assault/homicide was highest in infants ( Conclusion Injuries continue to be a leading cause of death in childhood in Scotland. Variation in causes of injury death by age-group is important when targeting preventive efforts. In particular, the threats of assault/homicide in infants, fire in 1–4 year-olds, pedestrian injury in 5–14 year-olds, and suicide in 10–14 year-olds need urgent consideration for preventive action.

    Children with traumatic brain injuries (TBI) commonly present with socioemotional difficulties, as well as accompanying multiple cognitive impairments. Often difficulties worsen at around 10 years old. This change is associated with frontal system changes, and tests of executive function (EF) predict outcome. However, children with TBI sometimes present with socioemotional difficulties despite apparent cognitive recovery. Our aims were to explore potential cognitive and socioemotional effects following childhood TBI, before and after the age of 10 years. We also wanted to identify cognitive correlates of psychosocial dysfunction. Measures of cognitive function and socioemotional disturbance administered to 14 children with TBI aged 8-10 years, and 14 children with TBI aged 10-16 years, were compared to control data from 22 non-injured 8- to 10 year-olds and 67 non-injured 10- to 16-year-olds. Results indicated that only the older group of children with TBI were impaired in tests of EF, but significant socioemotional difficulties were commonly evident in both groups. Processing speed (as well as EF) was found to correlate with socioemotional disturbance. We conclude that poor processing speed may also index the risk of socioemotional difficulties, but our general findings indicate that cognitive functions relevant to socioemotional functioning are not readily testable in younger children and are not strongly associated with such outcomes as they may be in adults.

    The negative effects of cigarette smoking on human reproduction and on birth weight are well documented. On the other hand ABO system, encoding for glycosyltransferases, contributes to biosynthesis of antigens and oligosaccharide structures involved in blastocyst adhesion and intrauterine selection. In this paper we have searched for possible interaction between ABO system and smoking concerning their effects on maternal age at child bearing and on birth weight. We have studied 395 consecutive healthy puerperae from the White Caucasian population of Rome. ABO blood group was determined by standard laboratory methods. Three-way contingency table analysis was performed according to Sokal and Rohlf and Chi square test of independence by SPSS programs. The proportion of smokers is higher in A phenotype than in other ABO types among young puerperae (≤ 24 years) while it is lower in A phenotype than in other types among older women. The negative effects of smoke on birth weight is much more evident in women with A blood group than in women carrying other ABO phenotypes. The interaction between smoking and ABO blood groups concerning their effects on birth weight is influenced by gender of newborn and by maternal age. ABO blood groups and smoking could have a joint influence on maternal age at child bearing and on birth weight. Copyright © 2011 Elsevier Ireland Ltd. All rights reserved.

    Archean aged rocks from the Pilbara Block area of western Australia (Warrawoona Group, Towers Formation, -3.3-3.5 Ga) contain microfossils that are composed of various sizes of spheres and filaments. The first descriptions of these microfossils were published in the late 1970's (Dunlop, 1978; Dunlop, et. al., 1978). The authenticity of the microfossils is well established. The small size of the microfossils prevents isotope dating, at least with the present technology. Microbiologists, however, have established guidelines to determine the authenticity of the Archean aged organic remains (Schopf, Walter, 1992).

    Full Text Available INTRODUCTION: Streptococcus pneumoniae is a worldwide occurring pathogen Nasopharyngeal carriage of Streptococcus pneumoniae precedes pneumonia and other pneumococcal diseases in the community. Little is known about S. pneumoniae carriage in Indonesia, complicating strategies to control pneumococcal diseases. We investigated nasopharyngeal carriage of S. pneumoniae in Semarang, Indonesia. METHODS: A population-based survey was performed in Semarang, Indonesia. Nasopharyngeal swabs and questionnaires were taken from 496 healthy young (6-60 month-old children and 45-70 year-old adults. RESULTS: Forty-three percent of children aged 6-60 months and 11% of adults aged 45-75 years carried S. pneumoniae. Determinants of carriage were being a child (OR 7.7; 95% CI = 4.5-13.0, passive smoking (OR 2.1; 95% CI = 1.3-3.4, and contact with toddler(s at home (OR 3.0; 95% CI = 1.9-4.7. The most frequent serotypes found were 6A/B and 15B/C. The current commercially available vaccines cover <50% serotypes found in children. Twenty-four percent of S. pneumoniae strains were penicillin non-susceptible, and 45% were resistant to cotrimoxazol. CONCLUSIONS: The limited coverage of commercially available vaccines against the serotypes found in this population, and the high proportion of non-susceptibility to penicillin and cotrimoxazol suggest the need for region-specific information and strategies to control S. pneumoniae.

    Osteoarthritis is a common indication for hip and knee arthroplasty. An accurate assessment of current trends in healthcare utilization as they relate to arthroplasty may predict the needs of a growing elderly population in the United States. First, incidence data was queried from the United States Nationwide Inpatient Sample from 1993 to 2009. Patients undergoing total knee and hip arthroplasty were identified. Then, the United States Census Bureau was queried for population data from the same study period as well as to provide future projections. Arthroplasty followed linear regression models with the population group >64 years in both hip and knee groups. Projections for procedure incidence in the year 2050 based on these models were calculated to be 1,859,553 cases (hip) and 4,174,554 cases (knee). The need for hip and knee arthroplasty is expected to grow significantly in the upcoming years, given population growth predictions.

    Full Text Available For many philosophers working in the area of Population Ethics, it seems that either they have to confront the Repugnant Conclusion (where they are forced to the conclusion of creating massive amounts of lives barely worth living, or they have to confront the Non-Identity Problem (where no one is seemingly harmed as their existence is dependent on the “harmful” event that took place. To them it seems there is no escape, they either have to face one problem or the other. However, there is a way around this, allowing us to escape the Repugnant Conclusion, by using what I will call Negative Average Preference Utilitarianism (NAPU – which though similar to anti-frustrationism, has some important differences in practice. Current “positive” forms of utilitarianism have struggled to deal with the Repugnant Conclusion, as their theory actually entails this conclusion; however, it seems that a form of Negative Average Preference Utilitarianism (NAPU easily escapes this dilemma (it never even arises within it.

This is a descriptive research. The study group included parents of 78 healthy children between the ages of 4-7 years who received or still receive pre-school education. “KINDL”4-7 Age Family Form was used to collect data as parents would assess life quality of their children indirectly. SPSS 15.0 package program was used to analyze the data. Mann-Whitney U Test and Kruskal-Wallis H Test were used to determine whether there is a difference between scale scores related to socio-demographic features. According to parents’ views, the factors on which children have highest life quality are “family” (  =83.21, “kindergarten” (  =82.82, “emotional well-being” (  =81.99, “social relationships” (  =81.67, respectively.

    Results: The microscopic anatomy of the spleen was observed at different gestational age. At first trimester the spleen was covered with a capsule. The lymphoid aggregations were observed throughout the spleen without any well differentiated red pulp. At second trimester the lymphoid aggregations started differentiating around the central arteriole forming the periarteriolar lymphoid sheath by 20 weeks. The red pulp was distinctly observed containing the RBCs and sinusoids and the white pulp containing lymphoid follicles were observed by 23rd week. At third trimester distinct red and white pulp was observed. By 30th week well developed lymphoid follicles with central arteriole were seen. At 36 weeks the central arteriole was seen at the periphery of the lymphoid follicle. Conclusion: A detailed description of the development of parenchymal and vascular components is essential in understanding the normal development of spleen. [Cukurova Med J 2015; 40(1.000: 36-41

    As part of a study of the morbidity of a group of workers made redundant from a meat products factory, the health of employees nearing retirement has been investigated. Consultations, episodes of illness and referrals to and attendances at hospital outpatient departments were recorded annually as the indices of morbidity. With the threat of redundancy a significant increase in morbidity was noted for the male employees but not for the female employees. It is suggested that these men adapt less easily to redundancy than the women.

    The emotional turmoil patients endure following a diagnosis of cancer can impair their ability to retain complex treatment-related information. Manoeuvres which increase the intensity of information have been shown to increase the amount retained. Providing details of treatment in a video format is one method of intensifying information provision, but the attitudes of patients to this format have not previously been evaluated. In this pilot study, the attitudes of 300 patients to video directed information were evaluated via questionnaires, of which 210 (70%) were returned. Eighty-nine per cent had easy access to a video cassette player. A highly significant number felt that the video would be very helpful or helpful (78%) compared to not helpful, worrying or equivocal 21% (P < 0.0001). This trend was particularly strong in patients < 60 years (83% versus 17%) (P < 0.0001) and those from ethnic groups (95% versus 5%) (P < 0.0001). As a result of this trial, a 20-min film (HEP) has been commissioned. It describes details of the two main treatments for cancer after surgery, namely chemotherapy and radiotherapy, shows patients actually having treatment, and explains the common side-effects and ways to alleviate them. Patients satisfaction with the film and its effect on anxiety and depression are currently being evaluated in an international prospective randomized trial. If it proves advantageous for patients--in view of the ethnic group bias in this study--it will be translated into the ethnic languages of the UK.

    Full Text Available Malnutrition has now been redefined in terms of “under nutrition” and conceptualized in terms of thinness which is an important problem among children and adolescents in rural areas of developing countries like India. Therefore, present study was carried out to assess the prevalence of thinness among the adolescent girls (age group 13yrs-18yrs of Garhkhal Village of Himachal Pradesh, India. The study design was cross-sectional. Height and weight were measured and Body Mass Index (BMI was carried out. Identification of thinness was done according to the new International BMI-based classification cut offs as given by Cole et al., 2007. In general the mean BMI increased with increasing age. Overall age-combined prevalence was 79.5%. Present study indicated the poor health status of the adolescent girls of the selected area which indicates the high nutritional stress among them as evident from the thinness prevalent among them.

    This study asks if the prevalence of loneliness in the population varies depending on the measures used, with special focus on loneliness among the elderly. The study compares loneliness in different age groups between 18 and 81 years old (N = 14,743) using two measures of loneliness: the (indirect) six-item De Jong Gierveld Loneliness Scale and a single-item, direct question about loneliness. Data are from the Norwegian LOGG (Life Course, Generation, and Gender) study. We compare the findings on loneliness according to age, gender, health, and partner status. Overall, the two loneliness measures indicate a similar prevalence of loneliness, but attribute loneliness to somewhat different people. When using a direct measure, loneliness is more prevalent among women; when using the (indirect) De Jong Gierveld Scale, loneliness is more prevalent among men. Also, the association between age and loneliness differed when using the direct and the indirect measure.

    Padian, Kevin

    1989-05-01

    The Glen Canyon Group (Moenave, Wingate, Kayenta and Navajo Formations) of northern Arizona represents an extensive outcrop of early Mesozoic age terrestrial sediments. The age of these formations has long been disputed because independent stratigraphic data from marine tie-ins, paleobotanical and palynological evidence, and radiometric calibrations have been scanty or absent. The fauna of the Kayenta Formation in particular has been problematic because it has appeared to contain both typical Late Triassic and Early Jurassic taxa Here I report that the principal evidence for Late Triassic taxa, dermal scutes previously assigned to an aetosaur, in fact belongs to the thyreophoran ornithischian dinosaur Scelidosaurus, previously known only as a washed-in form found in marine sediments in the Early Jurassic of England. The presence of this dinosaur represents the first vertebrate biostratigraphic tie-in of the Glen Canyon Group horizons with reliably dated marine deposits in Europe. Together with revised systematic assessments of other vertebrates and independent evidence from fossil pollen, it supports an Early Jurassic age for the Kayenta Formation and most or all of the Glen Canyon Group.

    Wet mount microscopy is the most commonly used diagnostic method for trichomoniasis in clinical diagnostic services all over the world including Sri Lanka due to its availability, simplicity and is relatively inexpensive. However, Trichomonas culture and PCR are the gold standard tests. Unfortunately, neither the culture nor PCR is available for the diagnosis of trichomoniasis in Sri Lanka. Thus, it is important to validate the wet mount microscopy as it is the only available diagnostic test and has not been validated to date in Sri Lanka. The objective was to evaluate the validity and reliability of wet mount microscopy against gold standard Trichomonas culture among clinic based population of reproductive age group women in Western province, Sri Lanka. Women attending hospital and institutional based clinics were enrolled. They were interviewed and high vaginal swabs were taken for laboratory diagnosis by culture and wet mount microscopy. There were 601 participants in the age group of 15-45 years. Wet mount microscopy showed 68% sensitivity, 100% specificity, 100% positive (PPV) and 98% negative predictive values (NPV) (P=0.001, kappa=0.803) respectively against the gold standard culture. The area under the ROC curve was 0.840. Sensitivity of wet mount microscopy is low. However it has high validity and reliability as a specific diagnostic test for trichomoniasis. If it is to be used among women of reproductive age group in Western province, Sri Lanka, a culture method could be adopted as a second test to confirm the negative wet mount for symptomatic patients.

    The fundamental tactical principles of the game of soccer represent a set of action rules that guide behaviours related to the management of game space. The aim of this study was to compare the performance of fundamental offensive and defensive tactical principles among youth soccer players from 12 to 17 years old. The sample consisted of 3689 tactical actions performed by 48 soccer players in three age categories: under 13 (U-13), under 15 (U-15), and under 17 (U-17). Tactical performance was measured using the System of Tactical Assessment in Soccer (FUT-SAT). The Kruskal Wallis, Mann-Whitney U, Friedman, Wilcoxon, and Cohen's Kappa tests were used in the study analysis. The results showed that the principles of "offensive coverage" (p = 0.01) and "concentration" (p = 0.04) were performed more frequently by the U-17 players than the U-13 players. The tactical principles "width and length" (p < 0.05) and "defensive unit" (p < 0.05) were executed more frequently by younger soccer players. It can be concluded that the frequency with which fundamental tactical principles are performed varies between the gaming categories, which implies that there is valuation of defensive security and a progressive increase in "offensive coverage" caused by increased confidence and security in offensive actions.

Heart rate was simultaneously recorded using ECG and SMB in fifteen participants [mean (SD age 27.3 (13.9 years, height 177.4 (10.2 cm and body mass 66.8 (15.3 kg] during an orthostatic tilt test. The two datasets were analysed to compare the number and type of R-R interval artefacts and indices from HRV (RMSSD, pNN50, HF, LF, SD1, and SD2. For artefact detection, 16,742 R-R intervals were analysed during all recordings. Only 18 artefacts, 9 type 1 (long R-R interval and 9 type 2 (short R-R interval, were identified with the SMB. Bland-Altman analysis indicated excellent accuracy for the SMB, with limits of agreement of -2.00 and +1.94 ms. Further, the reference and SMB systems were strongly correlated. The similarity between each device indicated that the SMB could reliably record R-R intervals.

    This acoustic study examines sound (vowel) change in apparent time across three successive generations of 123 adult female speakers ranging in age from 20 to 65 years old, representing three regional varieties of American English, typical of western North Carolina, central Ohio and southeastern Wisconsin. A set of acoustic measures characterized the dynamic nature of formant trajectories, the amount of spectral change over the course of vowel duration and the position of the spectral centroid. The study found a set of systematic changes to /I, ε, æ/ including positional changes in the acoustic space (mostly lowering of the vowels) and significant variation in formant dynamics (increased monophthongization). This common sound change is evident in both emphatic (articulated clearly) and nonemphatic (casual) productions and occurs regardless of dialect-specific vowel dispersions in the vowel space. The cross-generational and cross-dialectal patterns of variation found here support an earlier report by Jacewicz, Fox, and Salmons (2011) which found this recent development in these three dialect regions in isolated citation-form words. While confirming the new North American Shift in different styles of production, the study underscores the importance of addressing the stress-related variation in vowel production in a careful and valid assessment of sound change.

    This acoustic study examines sound (vowel) change in apparent time across three successive generations of 123 adult female speakers ranging in age from 20 to 65 years old, representing three regional varieties of American English, typical of western North Carolina, central Ohio and southeastern Wisconsin. A set of acoustic measures characterized the dynamic nature of formant trajectories, the amount of spectral change over the course of vowel duration and the position of the spectral centroid. The study found a set of systematic changes to /I, ε, æ/ including positional changes in the acoustic space (mostly lowering of the vowels) and significant variation in formant dynamics (increased monophthongization). This common sound change is evident in both emphatic (articulated clearly) and nonemphatic (casual) productions and occurs regardless of dialect-specific vowel dispersions in the vowel space. The cross-generational and cross-dialectal patterns of variation found here support an earlier report by Jacewicz, Fox, and Salmons (2011) which found this recent development in these three dialect regions in isolated citation-form words. While confirming the new North American Shift in different styles of production, the study underscores the importance of addressing the stress-related variation in vowel production in a careful and valid assessment of sound change.

    The benefit of monopolizing a limited resource is influenced by competitor density and by the relative competitive ability of defenders and intruders. Nevertheless, few studies have investigated the effect of density on resource defence in groups with large asymmetries in competitive ability...... and constitute more than half of the total population biomass. In this experiment, the ability of one yearling to monopolize a concentrated food source was observed at four densities of under-yearlings (zero, two, six and 12) in an indoor seminatural stream. We predicted that the success of defence would...... decrease with increasing under-yearling density and that the frequency of defence (i.e. aggression) would peak at an intermediate density. As predicted, yearlings made significantly more unsuccessful foraging attempts and adopted darker body coloration at high density of under-yearlings, suggesting...

    Objective: To determine the appropriate treatment regimen and the clinical course of the lower respiratory tract infections(RTIs) and to detect the common viral causes of lowerRTIs. Methods:The present study included a total of 255 pediatric patients aged less than 7 years old and admitted to the Department of Pediatrics of Rize Training and Research Hospital between January 2014 and January 2015 with clinical pre-diagnosis of lowerRTI. Nasopharyngeal swab specimens collected from these patients were tested for viral pathogens by using multiplexRT-PCR kit the ResPlex II plus PanelPRE (Qiagen, Germany). Results: A total of 212 out of 255 (83.1%) specimens revealed positive for one or more viral pathogens. The most common detected pathogens were respiratory syncytial virus (RSV) A/B in 110 samples (43.1%), rhinovirus in 51 samples (20.0%), adenovirus in 36 samples (14.1%), influenzae virus A in 32 samples (12.5%), and coronavirus in 24 samples (9.4%). In 76 samples (29.8%), more than one viral pathogen were detected.RSV was seen in more than 50% patients in the first 2 years.RSV was the most common pathogen in each year of the first 5 years but rhinovirus, influenza A and adenovirus were seen more thanRSV after the fifth year. A total of 95.8% of the viral detections were seen between November and April without a significant peak amongst these months. The distribution of the pathogens by months of the year showed no significance. Conclusions:These findings can contribute to epidemiological data of Turkey. Detection of the viral pathogens causing lowerRTIscan be critical in management of the disease, decrease inappropriate antibiotic treatment, and lower the morbidity and mortality rates in such diseases.

    Full Text Available (Pengaruh Usia dan Pendidikan terhadap Pola Konsumsi Kue Tradisional di Banda Aceh  ABSTRACT. Traditional finger foods are closely related to the culture and habits of the population where the foods are produced and carry a symbolic value. The perception of local citizens towards the consumption of traditional foods will affect the existence and integrity of these foods. Primary research was done by interviewing 263 consumers of traditional finger food in Banda Aceh, Indonesia, between April and May 2011. Demography factors are believed to have strong influence in the consumption pattern of traditional finger food in Banda Aceh. The interviews were performed by using a structured questionnaire. The questionnaire consists of dichotomous, multiple-choice questions and scale questions. The sampling technique which was used is a nonprobability with convenience approach in order to select consumers of traditional food. The data analysis was processed by descriptive and bivariate analysis using Chi-square distribution. The results showed that demographic factors, such as age and education, have a correlation with consumer behavior and consumption habits of traditional finger foods. As a side dish, the consumption of these foods is usually related to special occasions and leisure time. Although most of the consumers are satisfied with the traditional finger foods they consume, some improvements are still needed to enhance the quality and appearance of the products based on the respondents demand. These demands, such as improvement in taste and packaging are potential factors in supporting the increase of consumption of traditional finger food in Banda Aceh.

     To compare the effectiveness of flexible sigmoidoscopy in screening for colorectal cancer by patient sex and age.  Pooled analysis of randomised trials (the US Prostate, Lung, Colorectal and Ovarian cancer screening trial (PLCO), the Italian Screening for Colon and Rectum trial (SCORE), and the Norwegian Colorectal Cancer Prevention trial (NORCCAP)).  Aggregated data were pooled from each randomised trial on incidence of colorectal cancer and mortality stratified by sex, age at screening, and colon subsite (distal v proximal).  Invited individuals aged 55-74 (PLCO), 55-64 (SCORE), and 50-64 (NORCCAP). Individuals were randomised to receive flexible sigmoidoscopy screening once only (SCORE and NORCCAP) or twice (PLCO), or receive usual care (no intervention).  287 928 individuals were included in the pooled analysis; 115 139 randomised to screening and 172 789 to usual care. Compliance rates were 58%, 63%, and 87% in SCORE, NORCCAP, and PLCO, respectively. Median follow-up was 10.5 to 12.1 years. Screening reduced the incidence of colorectal cancer in men (relative risk 0.76; 95% confidence interval 0.70 to 0.83) and women (0.83; 0.75 to 0.92). No difference in the effect of screening was seen between men younger than 60 and those older than 60. Screening reduced the incidence of colorectal cancer in women younger than 60 (relative risk 0.71; 95% confidence interval 0.59 to 0.84), but not significantly in those aged 60 or older (0.90; 0.80 to 1.02). Colorectal cancer mortality was significantly reduced in both younger and older men, and in women younger than 60. Screening reduced colorectal cancer incidence to a similar extent in the distal colon in men and women, but there was no effect of screening in the proximal colon in older women with a significant interaction between sex and age group (P=0.04).  Flexible sigmoidoscopy is an effective tool for colorectal cancer screening in men and younger women. The benefit is smaller and not statistically

    maximum temperature in the summer months was used. Trend and seasonalities were adequately controlled for, as were air pollutant concentrations. Autoregressive moving average (ARIMA and Poisson regression models were used. Results: In all age groups except that aged less than 10 years old, there was an association between extremely high temperatures and mortality. Independently of age group, the temperature threshold above which mortality increased coincided with the 95th percentile of the maximum temperature data series for the summer months, which in Madrid is 36.5 °C. The daily mortality increment for each degree above this threshold was practically constant between the ages of 18 to 64 years but markedly increased in persons aged more than 65 years old. Conclusions: Mortality is associated with high temperatures in people younger than 64 years old and therefore prevention plans should not be focused exclusively on the elderly.

    Bone age assessment is a procedure performed in pediatric patients to quickly evaluate parameters of maturation and growth from a left hand and wrist radiograph. Pietka and Cao have developed a Computer-aided diagnosis (CAD) method of bone age assessment based on a digital hand atlas. The aim of this paper is to extend their work by automatically select the best representative image from a group of normal children based on specific bony features that reflect skeletal maturity. The group can be of any ethnic origin and gender from one year to 18 year old in the digital atlas. This best representative image is defined as the "average" image of the group that can be augmented to Piekta and Cao's method to facilitate in the bone age assessment process.

    Patients with sickle cell disease have been documented to be particularly susceptible to osteoarticular infections. Controversy exists concerning the bacteriology, etiology, and clinical presentation in differentiating osteoarticular infections from bone infarct. We retrospectively reviewed all cases from our institution over the past 22 years of osteoarticular infections in children who carry the diagnosis of sickle cell disease. Two thousand consecutive patient charts of children enrolled in the Pediatric Sickle Cell Clinic of our institution between 1973 and 1995 were evaluated. There were 14 cases of bone or joint infections (10 osteomyelitis, four septic arthritis). There was one case of multicentric osteomyelitis and one case of meningitis complicating the septic arthritis. There were nine male and five female patients with ages ranging from 6 months to 17 years (mean, 8.0). All patients were noted to have hemoglobin SS. The predominant presenting symptoms were pain (79% of cases) and swelling (71% of cases). The most frequent physical findings were fever >38.2 degrees C (71% of cases) and tenderness (86% of cases). Ninety-three percent of the children had a white blood count exceeding 15,000/mm3 (range, 7,900-32,300). Westergren sedimentation rates ranged from 14 to 89 mm/h with 93% of the children exceeding the normal value in our hospital. Cultures were positive in 75% of tissue biopsies, 58% of the blood cultures, and 70% of the bone or joint aspirates. The most common offending organism found in osteomyelitis was Salmonella (eight of 10 cases); however, no predominant organism found was identified in cases of septic arthritis. Radiographs and bone scans were of limited value in the differential diagnosis between osteoarticular infections and bone infarction. Early diagnosis and treatment of osteoarticular infections is key to satisfactory outcome. This study suggests that an ill-appearing patient with a fever >38.2 degrees C, pain, and swelling should

    Full Text Available OBJECTIVE: The purpose of this study was to (1 describe the distribution of Chlamydia trachomatis (CT and Human Immunodeficiency Virus (HIV cases across gender and age groups in Libreville (Gabon; (2 examine Gabonese Sexually Transmitted Infections (STIs-related risk behaviour. METHODS: The sampled population was people attending the "Laboratoire National de Santé Plublique". Between 2007 and 2011, 14 667 and 9 542 people respectively, were tested for CT and HIV infections. 1 854 of them were tested for both infections. We calculated CT and HIV rates across gender and age groups. Also analysed was the groups' contribution to the general CT and HIV epidemiology. STIs-related risk behaviours were assessed in 224 men and 795 women (between July 2011 and March 2013 who agreed and answered a questionnaire including questions on their marital status, number of sex partners, sexual practices, history of STIs, sex frequency and condom use. RESULTS: Data showed a 24% dropped in the CT infection rate between 2007 and 2010, followed by a 14% increase in 2011. The HIV infection rates for the same period were between 15% and 16%. The risk of a CT-positive subject getting HIV is about 0.71 times the risk of a CT-negative subject. Young adult aged between 18 and 35 years old represented 65.2% of people who had STIs. 80% of women and 66% of men confessed to an inconsistent use of condoms. 11.6% of women and 48% of men declared having multiple sex partners. 61% of questioned women and 67% of men declared knowing their HIV status. CONCLUSIONS: In this Gabonese setting, the population-aged from 18 to 35 years is the most affected by STIs. Other matters of concern are the inconsistent use of protection and sex with non-spousal or non-life partners.

  18. Predicting stuttering from linguistic factors for German speakers in two age groups.

    Brown's factors [J. Speech Disorders 10 (1945) 181] predict the likely loci of disfluency in English-speaking adults who stutter. A word is more likely to be stuttered for these speakers if it is a content word, starts with a consonant, is positioned at the beginning of a sentence, and if it is a long word. These same factors were examined in native German-speaking children and adults who stutter. Speech data of 15 German adults and 17 children were coded according to Brown's factors. For the adult group, it was predicted that words starting with consonants would not lead to as much of an increase in disfluencies compared with English samples, because of cross-linguistic differences in syllable onset properties. It was predicted that stuttering would be more likely in later sentence positions in German because in German the verb is usually near the end of a sentence. There were no obvious reasons to expect differences on the two remaining factors, content words and word length. With children, it was hypothesised that Brown's factors that specify level of linguistic difficulty would not be such a good predictor of stuttering rate. Specifically, it was predicted that the difference in stuttering rate between function and content words would be lower in children. For the adults both word type (content/function) and word length increased stuttering rate significantly, whereas changes in stuttering rate for the other two factors were non-significant. It was also found that when word difficulty (based on a combined measure of all factors) increased, stuttering rate rose. With children, only the word-length factor was significant, and stuttering rate was not governed to the same extent by overall word difficulty. Conclusions are drawn as to the effect of linguistic and motor influences on stuttering. The reader will learn about and be able to describe: (1) how linguistic factors affect stuttering rates in German; (2) the different patterns of adults and children who

    The land use/land cover transformation in Malaysia is enormous due to palm oil plantation which has provided huge economical benefits but also created a huge concern for carbon emission and biodiversity. Accurate information about oil palm plantation and the age of plantation is important for a sustainable production, estimation of carbon storage capacity, biodiversity and the climate model. However, the problem is that this information cannot be extracted easily due to the spectral signature for forest and age group of palm oil plantations is similar. Therefore, a noble approach "multi-scale and multi-texture algorithms" was used for mapping vegetation and different age groups of palm oil plantation using a high resolution panchromatic image (WorldView-1) considering the fact that pan imagery has a potential for more detailed and accurate mapping with an effective image processing technique. Seven texture algorithms of second-order Grey Level Co-occurrence Matrix (GLCM) with different scales (from 3×3 to 39×39) were used for texture generation. All texture parameters were classified step by step using a robust classifier "Artificial Neural Network (ANN)". Results indicate that single spectral band was unable to provide good result (overall accuracy = 34.92%), while higher overall classification accuracies (73.48%, 84.76% and 93.18%) were obtained when textural information from multi-scale and multi-texture approach were used in the classification algorithm.

    The gut microbiota contributes to host health by maintaining homeostasis, increasing digestive efficiency, and facilitating the development of the immune system. The composition of the gut microbiota can change dramatically within and between individuals of a species as a result of diet, age, or habitat. Therefore, understanding the factors determining gut microbiota diversity and composition can contribute to our knowledge of host ecology as well as to conservation efforts. Here we use high-throughput sequencing to describe variation in the gut microbiota of the endangered ring-tailed lemur (Lemur catta) at the Bezà Mahafaly Special Reserve (BMSR) in southwestern Madagascar. Specifically, we measured the diversity and composition of the gut microbiota in relation to social group, age, sex, tooth wear and loss, and habitat disturbance. While we found no significant variation in the diversity of the ring-tailed lemur gut microbiota in response to any variable tested, the taxonomic composition of the gut microbiota was influenced by social group, age, and habitat disturbance. However, effect sizes were small and appear to be driven by the presence or absence of relatively low abundance taxa. These results suggest that habitat disturbance may not impact the lemur gut microbiota as strongly as it impacts the gut microbiota of other primate species, highlighting the importance of distinct host ecological and physiological factors on host-gut microbe relationships.

    This post hoc meta-analysis evaluated the efficacy and safety of desvenlafaxine 50 and 100 mg versus placebo across age groups and severity of depression at baseline in patients with major depressive disorder. Data from placebo and desvenlafaxine 50-mg and 100-mg dose arms were pooled from 9 short-term, placebo-controlled, major depressive disorder studies (N = 4279). Effects of age (18-40 years, >40 to depression severity (mild, 17-item Hamilton Rating Scale for Depression total score [HAM-D17] ≤18; moderate, HAM-D17 >18 to depression and function compared with placebo for patients 18 to 40 years, older than 40 to younger than 55 years, and 55 to younger than 65 years, with no significant evidence of an effect of age. Desvenlafaxine significantly improved most measures of depression and function in moderately and severely depressed patients. There was a significant baseline severity by treatment interaction for HAM-D17 total score only (P = 0.027), with a larger treatment effect for the severely depressed group. Desvenlafaxine significantly improved depressive symptoms in patients younger than 65 years and in patients with moderate or severe baseline depression. Sample sizes were not adequate to assess desvenlafaxine efficacy in patients 65 years or older or with mild baseline depression.

    Full Text Available The follow-up study was designed to assess and to compare the effects of sensitivity to reward, sensitivity to punishment and family environment on internalizing and externalizing problems in a community sample of 477 children and adolescents aged 3-18 (50% female. The level of problem behavior at Time 1 in all age groups was the best predictor of corresponding type of problem level at Time 2; the residual variance in problem behavior was also predicted by sensitivity to reinforcement. Family factors contributed for change in externalizing problems and hyperactivity in preschool and middle childhood children; living in the urban environment was significant factor for peer problem. The study showed that individual differences interact with the family factors in the process of development, and family environment could strengthen or mitigate the influence of biological factors on children and adolescents’ adjustment.

    To estimate the prevalence of smoking among Brazilian youth, examining individual, family, and social group factors associated with this habit. Data from youth aged 15 to 24 years living in 17 Brazilian state capitals and the Federal District, obtained from the Household Survey on Risk Factors for Chronic Diseases and Reported Morbidity carried out in 2002 and 2003 by the National Cancer Institute was analyzed. Individual variables (sex, age, schooling, alcohol consumption, self-rated health, physical activity, current school attendance), family variables (age and education of head of household and father, mother, or sibling smoking), and social group variables (best friend smoking, most friends smoking, boyfriend/girlfriend smoking) were analyzed. Generalized estimating equations (GEE) approach to evaluate the factors associated with smoking were used. Considering the effect of the sampling design, smoking prevalence was 12.8%, ranging from 6.8% in Aracaju to 24.1% in Porto Alegre. The following factors were predictors of smoking: male sex, older age, less schooling, not attending school at the time of the survey, poorer health perception, and alcohol consumption. Peer smoking (friends or boyfriend/girlfriend) and smoking among family members (father/mother or sibling) were associated with smoking. There was an effect of parental birth cohort on smoking, with a higher prevalence of smoking among youth whose parents were born in the 1930s. Individual characteristics and the influence of peers and family were relevant for smoking by the youth. Increasing the dialogue among teenagers, school, schoolmates, friends, and parents could lead to a reduction of substance use among youth.

    Full Text Available The basic and fundamental role of Mg as being the second most abundant intercellular cation is established in various studies. It is identified as a divalent metal cofactor in over 300 enzymatic reactions involving energy metabolism and protein and nucleic acid synthesis. The biological function is identified in neuromuscular excitability. Mg ion regulates calcium ion flow in neuronal channels, helping to regulate neuronal Nitric Oxide production1. Mg deficiency causes NMDA coupled Calcium channels to be biased towards opening, causing neuronal injury & neurological dysfunction, which may appear to humans as major depression. The present study confirms a reduction in the symptoms of depression found in the male population comprising of different age group by Mg treatment. CSF Mg has been found low in treatment resistant suicidal depression. Brain Mg is also low in TRD using phosphorous nuclear magnetic resonance Spectroscopy2. A 2009 randomized clinical trial shows that Mg therapy was an effective as TCAs in depressed diabetics. Increase in brain Mg enhances both short term synaptic facilitation and long term potentiation and improves learning and memory function3 The present study is based on findings that male subjects diagnosed as depressed showed a marked reduction in behavioral and somatic features of the disease after administration of Magnesium supplement. Physiological and somatic anxiety was also alleviated in a certain age group which displayed recovery from Insomnia and agitation. Suicidal tendency was also negative in all age groups. This study focuses on the behavioral and somatic responses pertaining to brain biochemical changes induced by Magnesium therapy.

    Full Text Available INTRODUCTION Refractive error is the most common cause of visual impairment around the world and the second leading cause of treatable blindness. Very early detection and treatment of visual impairment in children results in a reduction in the number of school children with poor sight being uncorrected. AIM To study the prevalence of uncorrected refractive errors among children of 7-15 years of age group. MATERIALS AND METHODS A total of 958 children of age group 7-15 years were examined during a time period of 1 year from June 2014 to May 2015. The examination included visual acuity, slit lamp examination, auto refractometer, keratometry, A-Scan Biometry and fundoscopic examination. Patients were then taken to assess the refractive error under the cycloplegic effect of 1% homatropine by streak retinoscopy. Hyperopia was defined as spherical power of >+2.00 D, Myopia as -0.50 D. RESULTS Visual impairment (VA of 6/12 or worse in better eye was present in 8.14% of the children examined. The prevalence of myopia, hypermetropia and astigmatism was 4.70%, 1.24%, 2.2% respectively, Myopia was commonly seen in older age group children. CONCLUSION Refractive error was the main cause of visual impairment in children between 7-15 years. Myopia was the most common refractive error particularly in older children. Uncorrected refractive errors among children have a considerable impact on learning and their academic achievement. Diagnosis and correction of refractive error is the most effective form of eye care. As it is an easily treatable cause of visual impairment, effective strategies should be developed to eliminate refractive error in children.

    Maglo, Koffi N

    2012-01-01

    This article addresses the philosophical and moral foundations of group-based and individualized therapy in connection with population care equality. The U.S. Food and Drug Administration (FDA) recently modified its public health policy by seeking to enhance the efficacy and equality of care through the approval of group-specific prescriptions and doses for some drugs. In the age of genomics, when individualization of care increasingly has become a major concern, investigating the relationship between population health, stratified medicine, and personalized therapy can improve our understanding of the ethical and biomedical implications of genomic medicine. I suggest that the need to optimize population health through population substructure-sensitive research and the need to individualize care through genetically targeted therapies are not necessarily incompatible. Accordingly, the article reconceptualizes a unified goal for modern scientific medicine in terms of individualized equal care.

    The aim of the study was to verify differences between age groups of female judo matches in time-motion and technical-tactical analysis. The sample was composed of pre-cadet (13-14 years, n = 148), cadet (15-16 years, n = 228), junior (17-19 years, n = 104) and senior (>20 years, n = 237) groups. The time-motion indicators consisted of total combat time, standing combat time, displacement without contact, gripping time, total time of techniques, groundwork combat time and pause time, per match and by each combat/pause cycle. Technical and tactical variables were also collected. The one-way analysis of variance and a post hoc test were conducted, P ≤ 0.05. Cadets, with a median of 7 (2, 12), had a number of combat/pause cycles different from junior, with 3 (1, 8.5). Regarding time-motion per match and per cycle, senior had longer total combat time, standing combat time and gripping time than other groups. Senior presented lower frequency of leg techniques than pre-cadet, cadet and junior. Time-motion and technical-tactical variables effects in female judo athletes emphasise the difference between seniors and other groups.

    Full Text Available The study aimed at detecting apoptotic endothelial cells (ECs and smooth muscle cells (SMCs together with determining expression of NF-kappaB (p105/p50 and Bax in varicose vein walls. Women (n=35 undergoing the excision of varicose veins were divided into 3 groups: younger than 35 years (I, 36–50 years (II, and older than 50 years (III. Apoptosis was determined by the TUNEL method, NF-kappaB and Bax expression by immunohistochemistry. The percentage of apoptotic ECs and SMCs in the layers of varicose vein wall increased in groups II and III. NF-kappaB expression had the lowest level in Group II with particularly low level in the media. Contrariwise, Bax expression levels in Group II were increased. The study revealed that in varicose veins ECs and SMCs apoptosis increased with advancing age. If increase in apoptosis during earlier stages of varicosities is probably regulated by intrinsic pathway, then in older patients other signaling pathways may be involved.

    Full Text Available Evaluation of individual maturity status takes an important role in selecting of the orthodontic treatment plans, especially for the growing age patient. This is mostly related to use of functional appliances and surgical approaches in some cases of skeletal discrepancy. Previous researches hae demonstrated the significant correlation between the mandible length and the cervical vertebrae maturation in Deutero-Malay group. The significant correlation between the cervical vertebrae and middle phalanx maturity, and the dental calcification within the Deutero-Malay group has been proven. Objective: To confirm the correlation between the mandible length and the dental calcification. Methods: This was an observational research with a cross-sectional design, done on 160 Deutero-Malay subjects, aged 8-16 years. The length of mandible was measured from Condylion to Gnathion, and the dental calcification was evaluated by Demirijan method. Results: of Spearman nonparametric correlation test indicated the significant correlation between the mandible length and canine calcification (r=0.713, the second premolar (r=0.753, and the second molar (r=0.772. The result of Multiple Classification Analysis showed that the highest correlation to the mandible length was the second molar calcification (ß=0.495.DOI: 10.14693/jdi.v17i1.107

Thirty six percent of junior women were overweight (BMI ≥25 kg/m² and 21% had central adiposity obese. Sixty eight year-old women had a far more adverse risk profile than 35 year-old women. In terms of energy consumption, 14 year-old women had the lowest fat intake and the highest consumption of carbohydrates whereas intake of protein was lowest in 10 year-old girls. Intake of unsaturated fat was lower in youths than in adults amounting to 37 g unsaturated fat respectively 53.4% of total fat consumption. The asso-ciation between energy consumption and overweight was significant and calorie intake was associated with clustering of ≥3 cardiovascular risk factors (OR :4.72; 95% CI 1.22-18.33.Conclusions: The prevalence of CVD risk factors increased continuously from girls and adolescents to junior and senior women. However, dietary intake was different in the four age groups. Caloric intake was associated with overweight and clustering of risk factors in adult women.

    To document the perceptions of indigenous peoples for the sustainable management of natural resources against malnutrition. Initially 4 and then 12 interviews were conducted with 4 different age groups. Eight rural villages in Guasaganda, central Ecuador, were studied in 2011-2012. A total of 75 people (22 children, 18 adolescents, 20 adults, and 15 elders). Benefits, severity, susceptibility, barriers, cues to action, and self-efficacy of eating traditional foods. Qualitative content analysis was completed using NVivo software. Initial analysis was inductive, followed by a content analysis directed by the Health Belief Model. Coding was completed independently by 2 researchers and kappa statistics (κ ≥ 0.65) were used to evaluate agreement. Healthy perceptions toward traditional foods existed and differed by age. Local young people ate traditional foods for their health benefits and good taste; adults cultivated traditional foods that had an economic benefit. Traditional knowledge used for consumption and cultivation of traditional foods was present but needs to be disseminated. Nutrition education in schools is needed that supports traditional knowledge in younger groups and prevents dietary changes toward unhealthy eating. Increased production of traditional food is needed to address current economic realities. Copyright © 2016 Society for Nutrition Education and Behavior. Published by Elsevier Inc.

    Cancer incidence and death statistics are typically recorded for multiple age and sex brackets, leading to large data tables which are difficult to digest. Effective visualizations of this data would allow practitioners, policy makers, and the general public to comprehend the data more readily and act on it appropriately. We introduce multilevel spie charts to create a combined visualization of cancer incidence and death statistics. Spie charts combine multiple pie charts, where the base pie chart (representing the general population) is used to set the angles of slices, and the superimposed ones use variable radii to portray the cancer data. Spie charts of cancer incidence and death statistics from Israel for 2009-2011 are used as an illustration. These charts clearly show various patterns of how cancer incidence and death distribute across age and sex groups, illustrating (1) absolute numbers and (2) rates per 100,000 population for different age and sex brackets. In addition, drawing separate charts for different cancer types illustrates relative mortality, both (3) across cancer types and (4) mortality relative to incidence. Naturally, this graphical depiction can be used for other diseases as well.

    Cases of child maltreatment are being increasingly reported in Taiwan. However, the trend or changes of child maltreatment in Taiwan are fragmentary and lack empirical evidence. This study analyzed the epidemiological characteristics of substantiated child maltreatment cases from the previous decade, using mortality as an indicator to investigate the care of children who experienced substantiated maltreatment in the past to determine any new developments. Data for analysis and estimates were retrieved from the Department of Statistics in the Ministry of the Interior from 2004 to 2013. Trend analyses were conducted using the Joinpoint Regression Program. The child maltreatment rate in Taiwan was found to have nearly tripled from 2004 to 2013. A greater increase in the maltreatment of girls than boys and the maltreatment of aboriginal children than non-aboriginal children was noted from 2004 to 2013. When stratified by age group, the increase in maltreatment was most pronounced in children aged 12-17 years, and girls aged 12-17 years experienced the greatest increase in maltreatment. In terms of the proportional changes of different maltreatment forms among substantiated child maltreatment cases, child neglect was decreasing. The increase in sexual abuse was higher than for any other form of maltreatment and surpassed neglect by the end of 2013. Furthermore, the mortality rate of children with substantiated maltreatment record is increasing in Taiwan, whereas the mortality rate among children without any substantiated maltreatment record is decreasing. The results of this study highlight the need for policy reform in Taiwan regarding child maltreatment.

    Introduction The lateral cephalometric skeletal discrepancy indicators play a major role in diagnosing and preparing a case for orthognathic surgeries and the dentofacial corrections. Aim The study was aimed to check the reliability and the predictability of different anterio-posterior skeletal discrepancy indicators in different age groups and to derive the most reliable indicator for the orthodontic diagnosis. Materials and Methods A cross-sectional study was conducted on a sample of 100 subjects including 29 adolescent (15 males and 14 females) and 71 adult (41 males and 30 females) subjects with the mean age of 19.05 ± 5.78 years. All the subjects had Angle’s Class I molar relationship. The lateral cephalograms of the sample were taken under the standard setting and hand tracing of the cephalometric radiographs using a sharp 4H pencil were made on acetate tracing paper. The anterio-posterior cephalometric indicators like β-angle, Wits appraisal (mm), Sella- Nasion plane to Point A and Point B distance (SN-AB mm) and Maxillo-Mandibular plane angle bisector to Point A and Point B distance (MM-AB mm) were measured. Intra-examiner reliability of tracings was evaluated using Intra Class Correlation (ICC) test. Mann Whitney U-test was applied for comparison of parameters between different malocclusion groups. Concurrent validity of various parameters was calculated using Cohen’s kappa. A p-value <0.05 was considered statistically significant. Results The comparison of intra-examiner reliability of tracings in Angle’s Class I adolescent group showed, MM-AB to have an almost perfect agreement followed by Wits. Intra-examiner reliability of tracings in Angle’s Class I adult group showed moderate agreement for Wits and MM-AB showed almost perfect agreement and all the parameters showed statistically significant ICC. Comparison of parameters between adolescent and adult, Angle’s Class I malocclusion group showed significant difference between adolescent and

    To determine the prevalence of adult malnutrition and associated risk factors in a post-conflict area of northern Uganda. A cross-sectional community survey was performed from September 2011 to June 2013. All registered residents in Gulu Health and Demographic Surveillance System aged 15 years and older were considered eligible. Trained field assistants collected anthropometric measurements (weight and height) and administered questionnaires with information on sociodemographic characteristics, food security, smoking and alcohol. Nutritional status was classified by body mass index. In total, 2062 men and 2924 women participated and were included in the analyses. The prevalence of underweight was 22.3% for men and 16.0% for women, whereas the prevalence of overweight was 1.5% for men and 7.6% for women. In men, underweight was associated with younger (15-19 years) and older age (>55 years) (P < 0.001), being divorced/separated [odds ratio (OR) = 1.91 (95% confidence interval (CI): 1.21-2.99] and smoking (OR = 2.13, 95% CI: 1.67-2.73). For women, underweight was associated with older age (P < 0.001) and hungry-gap rainy season (May-July) (OR = 1.33, 95% CI: 1.04-1.69). Widowed or divorced/separated women were not more likely to be underweight. No association was found between education, alcohol consumption or food security score and underweight. Our findings are not in line with the conventional target groups in nutritional programmes and highlight the importance of continuous health and nutritional assessments of all population groups that reflect local social determinants and family structures. © 2016 John Wiley & Sons Ltd.

    To provide an update on trends in asthma mortality in Brazil for two age groups: 0-4 years and 5-34 years. Data on mortality from asthma, as defined in the International Classification of Diseases, were obtained for the 1980-2014 period from the Mortality Database maintained by the Information Technology Department of the Brazilian Unified Health Care System. To analyze time trends in standardized asthma mortality rates, we conducted an ecological time-series study, using regression models for the 0- to 4-year and 5- to 34-year age groups. There was a linear trend toward a decrease in asthma mortality in both age groups, whereas there was a third-order polynomial fit in the general population. Although asthma mortality showed a consistent, linear decrease in individuals ≤ 34 years of age, the rate of decline was greater in the 0- to 4-year age group. The 5- to 34-year group also showed a linear decline in mortality, and the rate of that decline increased after the year 2004, when treatment with inhaled corticosteroids became more widely available. The linear decrease in asthma mortality found in both age groups contrasts with the nonlinear trend observed in the general population of Brazil. The introduction of inhaled corticosteroid use through public policies to control asthma coincided with a significant decrease in asthma mortality rates in both subsets of individuals over 5 years of age. The causes of this decline in asthma-related mortality in younger age groups continue to constitute a matter of debate.
