    Participation and performance trends for age group marathoners have been investigated for large city marathons such as the 'New York City Marathon' but not for mountain marathons. This study investigated participation and trends in performance and sex difference in the mountain marathon 'Jungfrau Marathon' held in Switzerland from 2000 to 2014 using single and mixed effects regression analyses. Results were compared to a city marathon (Lausanne Marathon) also held in Switzerland during the same period. Sex difference was calculated using the equation ([race time in women] - [race time in men]/[race time in men] × 100). Changes in sex differences across calendar years and were investigated using linear regression models. In 'Jungfrau Marathon', participation in all female and male age groups increased with exception of women in age groups 18-24 and men in age groups 30-34, 40-44 and 60-64 years where participation remained unchanged. In 'Lausanne Marathon', participation increased in women in age groups 30-34 to 40-44 years. In men, participation increased in age groups 25-29 to 44-44 years and 50-54 years. In 'Jungfrau Marathon' runners became slower across years in age groups 18-24 to 70-74 years. In 'Lausanne Marathon', runners became slower across years in age groups 18-24 and 30-34 to 65-69 years, but not for 25-29, 70-74 and 75-79 years. In 'Jungfrau Marathon', sex difference increased in age groups 25-29 (from 4 to 10 %) and 60-64 years (from 3 to 8 %) but decreased in age group 40-44 years (from 12 to 6 %). In 'Lausanne Marathon', the sex difference showed no changes. In summary, participation increased in most female and male age groups but performance decreased in most age groups for both the mountain marathon 'Jungfrau Marathon' and the city marathon 'Lausanne Marathon'. The sex differences were lower in the 'Jungfrau Marathon' (~6-7 %) compared to the 'Lausanne Marathon' where the sex difference was ~10-12 % from age groups 18-24 to 55

    Background Athletes intending to compete in Ironman Hawaii need to qualify in an age-group based qualification system. We compared participation and top ten performances of athletes in various age groups between Ironman Hawaii and its qualifier races. Methods Finishes in Ironman Hawaii and in its qualifier races in 2010 were analyzed in terms of performance, age, and sex. Athletes were categorized into age groups from 18–24 to 75–79 years and split and race times were determined for the top ten athletes in each age group. Results A higher proportion of athletes aged 25–49 years finished in the qualifier races than in Ironman Hawaii. In athletes aged 18–24 and 50–79 years, the percentage of finishes was higher in Ironman Hawaii than in the qualifier races. For women, the fastest race times were slower in Ironman Hawaii than in the qualifier races for those aged 18–24 (P<0.001), 25–29 (P<0.05), and 60–64 (P<0.05) years. Swim split times were slower in Ironman Hawaii than in the qualifier races for all age groups (P<0.05). Cycling times were slower in Ironman Hawaii for 18–24, 25–29, 40–44, 50–54, and 60–64 years (P<0.05) in age groups. For men, finishers aged 18–24 (P<0.001), 40–44 (P<0.001), 50–54 (P<0.01), 55–59 (P<0.001), 60–64 (P<0.01), and 65–69 (P<0.001) years were slower in Ironman Hawaii than in the qualifier races. Swim split times were slower in Ironman Hawaii than in the qualifier races for all age groups (P<0.05). Cycling times were slower in Ironman Hawaii for those aged 18–24 and those aged 40 years and older (P<0.05). Conclusion There are differences in terms of participation and performance for athletes in different age groups between Ironman Hawaii and its qualifier races. Triathletes aged 25–49 years and men generally were underrepresented in Ironman Hawaii compared with in its Ironman qualifier races. These athletes may have had less chance to qualify for Ironman Hawaii than female athletes or younger (<25

    Participation and performance trends in age group athletes have been investigated for different sport disciplines, but not for master swimmers. The knowledge on this topic is still missing for a particular stroke such as backstroke. Changes in participation and performance of male and female age group backstroke swimmers (≥25 years) competing in 50, 100 and 200 m pool swimming at the FINA World Masters Championships held between 1986 and 2014 were investigated using mixed-effects regression analyses. The overall participation was n = 26,217 including n = 13,708 women and n = 12,509 men. In 50 m, female (age groups 85-89 years; p = 0.002) and male participation (age groups 55-59; p = 0.030 and 80-84 years; p = 0.002) increased, while female participation decreased in age groups 55-59 (p = 0.010) and 60-64 years (p = 0.050). In 100 and 200 m, participation increased in age groups 45-49, 50-54, 65-69, 70-74, 80-84 years. Swimmers in age groups 25-29 to 95-99 years improved performance over all distances. Women were slower than men in age groups 25-29 to 80-84 years, but not in age groups 85-89 to 95-99 years over all distances. In 50 m and 100 m, the sex difference decreased in age groups 40-44 (p = 0.007 and p = 0.005), 45-49 (p = 0.017 and p = 0.034), 50-54 (p = 0.002 and p = 0.040), to 55-59 years (p = 0.002 and p = 0.004). In 200 m, the sex difference decreased in age groups 40-44 (p = 0.044) and 90-94 (p = 0.011), but increased in age group 25-29 years (p = 0.006). In summary, in age group backstroke swimmers, (1) participation increased or remained unchanged (except women in age groups 55-59 and 60-64 years in 50 m), (2) swimming performance improved in all age groups from 25-29 to 95-99 years over all distances, (3) men were faster than women in age groups 25-29 to 80-84 years (except age groups 85-89 to 95-99 years) over time and all distances.

    2013-01-01

    Background Participation and performance trends in age group athletes have been investigated in endurance and ultraendurance races in swimming, cycling, running, and triathlon, but not in long-distance inline skating. The aim of this study was to investigate trends in participation, age, and performance in the longest inline race in Europe, the Inline One-Eleven over 111 km, held between 1998 and 2009. Methods The total number, age distribution, age at the time of the competition, and race times of male and female finishers at the Inline One-Eleven were analyzed. Results Overall participation increased until 2003 but decreased thereafter. During the 12-year period, the relative participation in skaters younger than 40 years old decreased while relative participation increased for skaters older than 40 years. The mean top ten skating time was 199 ± 9 minutes (range: 189–220 minutes) for men and 234 ± 17 minutes (range: 211–271 minutes) for women, respectively. The gender difference in performance remained stable at 17% ± 5% across years. Conclusion To summarize, although the participation of master long-distance inline skaters increased, the overall participation decreased across years in the Inline One-Eleven. The race times of the best female and male skaters stabilized across years with a gender difference in performance of 17% ± 5%. Further studies should focus on the participation in the international World Inline Cup races. PMID:23690697

    Kavanaugh, Andrea; Zin, Thanthan; Schmitz, Joseph; Rosson, Mary Beth; Kim, B. Joon; Carroll, John M.

    Voluntary associations serve crucial roles in local communities and within our larger democratic society. They aggregate shared interests, collective will, and cultivate civic competencies that nurture democratic participation. People active in multiple local groups frequently act as opinion leaders and create “weak” social ties across groups. In Blacksburg and surrounding Montgomery County, Virginia, the Blacksburg Electronic Village (BEV) community computer network has helped to foster nearly universal Internet penetration. Set in this dense Internet context, the present study investigated whether and how personal affiliation with local groups enhanced political participation in this high information and communication technology environment. This paper presents findings from longitudinal survey data which indicate that as individuals’ uses of information technology within local formal groups increase over time, so do their levels and types of involvement in the group. Furthermore, these increases most often appear among people who serve as opinion leaders and maintain weak social ties in their communities. Individuals’ changes in community participation, interests and activities, and Internet use suggest ways in which group members act upon political motivations and interests across various group types.

  15. Carboxyl group participation in sulfate and sulfamate group transfer reactions

    SciTech Connect

    Hopkins, A.; Williams, A.

    1982-04-23

    The pH dependence for the hydrolysis of N-(2-carboxyphenyl)sulfamic acid exhibits a plateau region corresponding to participation of the carboxyl function. A normal deuterium oxide solvent isotope effect indicates that proton transfer from the carboxylic acid is concerted with sulfamate group transfer to water. Hydrolysis of salicylic sulfate and N-(2-carboxyphenyl)sulfamate in /sup 18/O-enriched water yields salicylic acid and anthranilic acids with no enrichment, excluding catalysis by neighboring nucleophilic attack on sulfur by the carboxylate group. Intermolecular catalysis by carboxylic acids is demonstrated in the hydrolysis of N-(1-naphthyl)sulfamic acid; the mechanism is shown to involve preequilibrium protonation of the nitrogen followed by nucleophilic attack on sulfur by the carboxylate anion. Fast decomposition of the acyl sulfate completes the hydrolysis; this mechanism is considered to be the most efficient but is excluded in the intramolecular case which is constrained by the electronic requirements of displacement at the sulfur atom (6-ENDO-tet).

    2015-09-01

    In the present study, a computerized test was used to compare the attention level of a group of healthy older participants aged 75 with that of a group of students aged 31. The second part of the study examined only the older participants and sought to discover how three measures of lifestyle were related to measures of attention. The results showed that the young group performed better on measures of attention. No differences between the two age groups were found on measures of impulsivity and on four measures of sustained attention. A discriminant function analysis found that reaction time and standard deviation of reaction time can explain 87.50% of the variance in both groups. The older participants' answers to the lifestyle questions showed that variables of attention correlated significantly with time spent watching television and reading. The results indicate that attention level declines with age; however, no decline was observed on measures of impulsivity and sustained attention.

    Background Participation in a sports group is key for the prevention of incident functional disability. Little is known about the correlates of older adults’ participation in sports groups, although this could assist with the development of effective health strategies. The purpose of this study was to identify the demographic and biological, psychosocial, behavioral, social and cultural, and environmental correlates of sports group participation among Japanese older adults. Methods Data were obtained from the Japan Gerontological Evaluation study, which was a population–based cohort of people aged ≥65 years without disability enrolled from 31 municipalities across Japan (n = 78,002). Poisson regression analysis was used to determine the associations between the factors and participation in sports groups. Results Non-regular participation in sports groups was associated with lower educational level, being employed, and working the longest in the agricultural/forestry/fishery industry among the demographic and biological factors and poor self-rated health and depression among the psychosocial factors. Of the behavioral factors, current smoking was negatively associated and current drinking was positively associated with regular participation in sports groups. Among the social and cultural factors, having emotional social support and participating in hobby clubs, senior citizen clubs, or volunteer groups were associated with a high prevalence of participation in sports groups. Perceptions of the presence of parks or sidewalks, good access to shops, and good accessibility to facilities were positively associated with participation in sports groups among the environmental factors. Conclusions Our study suggests that the promotion of activities that could increase older adults’ participation in sports groups should consider a broad range of demographic and biological, psychosocial, behavioral, social and cultural, and environmental factors.

  5. Assessing group-level participation in fluid teams: testing a new metric.

    Paletz, Susannah B F; Schunn, Christian D

    2011-06-01

    Participation is an important factor in team success. We propose a new metric of participation equality that provides an unbiased estimate across groups of different sizes and across those that change size over time. Using 11 h of transcribed utterances from informal, fluid, colocated workgroup meetings, we compared the associations of this metric with coded equality of participation and standard deviation. While coded participation and our metric had similar patterns of findings, standard deviation had a somewhat different pattern, suggesting that it might lead to incorrect assessments with fluid teams. Exploratory analyses suggest that, as compared with mixed-age/status groups, groups of younger faculty had more equal participation and that the presence of negative affect words was associated with more dominated participation. Future research can take advantage of this new metric to further theory on team processes in both face-to-face and distributed settings.

    2015-07-01

    Ageing urban societies face the challenge of enabling a "good" life for older people in their neighbourhood areas. This article focuses on potential obstacles and required preconditions for processes of neighbourhood development, based on results from the research and development project "Quality of life of older people in their neighbourhood" (LiW). Preconditions and obstacles include political and organizational requirements, differing understandings of participation of local experts, as well as the organization of the process and the access to the process. Furthermore, problems and social conflicts, which have to be dealt with on the local level, are examined. An example for such conflicts are statements of group-focused enmity. The paper aims to point out the significials of such processes as well as potential barriers and limits in order to inform academics as well as practitioners and to contribute to the sustainable integration of participative neighbourhood development.

    Background Fewer than half of all U.S. adults meet the 2008 Physical Activity Guidelines. Leader behaviors and group cohesion have been associated with increased participation or adherence in sports team and exercise class settings. Physical activity interventions in community settings that encompass these factors may enhance intervention adherence. Purpose To examine the impact of Community Health Promoter leader behaviors and group cohesion on participation in a walking group intervention among racially/ethnically diverse adults in low-to-moderate income communities in Detroit, Mich. Design Data for the current study were drawn from the Walk Your Heart to Health (WYHH) data set. WYHH was a multi-site cluster randomized controlled study with a lagged intervention and outcome measurements at baseline, four, eight, and 32 weeks. Pooled survey data from both intervention arms is used for the current study. Data were analyzed between August 2013 and October 2014. Setting/participants A total of 603 non-Hispanic Black, non-Hispanic White, and Hispanic adults across five cohorts that began the 32-week WYHH intervention between March 2009 and October 2011. Intervention A 32-week long walking group program hosted by community- and faith-based organizations and facilitated by Community Health Promoters. Walking groups met three times per week for 90-minutes per session. To promote participation in or adherence to WYHH, Community Health Promoters used evidence-based strategies to facilitate group cohesion. Group members assumed increasing leadership responsibility for facilitating sessions over time. Main outcome measures Participation in WYHH as measured by consistency of attendance. Results Community Health Promoter leader behaviors were positively associated with participation in WYHH. Social but not task cohesion was significantly associated with consistent participation. Social cohesion may mediate the relationship between leader behaviors and walking group

    Kim, K C; Hurh, W M; Fernandez, M

    1989-01-01

    This study investigates ethnic and nativity differentials in self-employment based on the small-business experiences of 3 Asian immigrant groups in the US: Korean, Chinese, and Asian Indians. In light of the 1980 Census data, the intra- and the inter-group differences in the business participation rates of these Asian immigrant groups are examined. Findings reveal that each group has substantial intra-group differences in the business participation rate, and the differences can best be explained by the interactive approach proposed by this study. Moreover, a comparative study (inter-group comparison) of these intra-group differences opens a new avenue to understanding the various patterns of business participation among recent immigrants from Asia.

    2014-09-01

    A properly interpreted electrocardiogram (ECG) provides important information and is an inexpensive and easy test to perform. It continues to be the method of choice for the diagnosis of arrhythmias. Although the principles of cardiac electrophysiology are the same, there are anatomical and physiological age-dependent changes which produce specific alterations in the paediatric ECG, and which may be misinterpreted as pathological. The intention of this article is to address in a systematic way the most relevant aspects of the paediatric ECG, to propose a possible reading scheme of the ECG and to review the electrocardiograph tracings most frequently found in the paediatric age group.

    The aim of the study was to estimate dietary intake of lycopene by the group of 100 women, from Central Poland, in different age <30 years, 30-50 years, >50 years (mean age 49 +/- 16 years) and main sources of lycopene. The study was carried out in the year 2006 (June-July) with the use of 4-day dietary food records. The lowest intake of lycopene was noted in the youngest group--4.17 mg/person/day, the highest intake in the oldest group--4.88 mg/person/day. The main sources of lycopene in food rations were tomato products (50.6%) and fresh tomatoes (43.5%). Tropical fruit delivered 5.2% of lycopene, other fruit and vegetable juices only 0.7%. Intakes of products, sources of lycopene, depended on age of women and were statistically significant in case of tomato, watermelon, pink grapefruit, and tomato products: ketchup, liquid tomato sauces, liquid tomato soups, tomato juice.

  15. Low-income aged: eligibility ad participation in SSI.

    This article reports on a study undertaken to evaluate the Social Security Administration's (SSA) methods for estimating the number of persons eligible for Federal Supplemental Security Income (SSI) payments. SSA estimates that 65-70 percent of the aged eligible for SSI actually participate in the program. It has been argued that the actual participation rate may be either higher or lower than SSA estimates because SSA misestimates the size of the eligible population. SSA bases its estimates of the number of persons eligible on data in the Census Bureau's Current Population Survey (CPS). In this study, a sample of 2,000 low-income aged persons was interviewed in 1979, and two sets of information were collected: One duplicated the data used by SSA to make its estimates; the other duplicated the type of information collected when a person actually applies for SSI. When the two sets were compared, it was found that the methodology that SSA uses to estimate the size of the eligible population and the information collected from SSI applicants produced estimates that were quite similar. The study also evaluated theories to explain why some persons eligible for SSI do not claim benefits. The study found that the elderly are more likely to participate in SSI if they live in States that supplement Federal SSI payments and that do not have a history of imposing liens on the property of welfare recipients. Participants also tend to have somewhat lower incomes (excluding SSI) than nonparticipants. No evidence was found that variations in practices among Social Security district offices could account for differences in SSI participation rates.

  4. Locations that Support Social Activity Participation of the Aging Population

    2015-01-01

    Social activities are an important aspect of health and quality of life of the aging population. They are key elements in the prevention of loneliness. In order to create living environments that stimulate older adults to engage in social activities, more insight is needed in the social activity patterns of the aging population. This study therefore analyzes the heterogeneity in older adults’ preferences for different social activity location types and the relationship between these preferences and personal and mobility characteristics. This is done using a latent class multinomial logit model based on two-day diary data collected in 2014 in Noord-Limburg in the Netherlands among 213 respondents aged 65 or over. The results show that three latent classes can be identified among the respondents who recorded social activities in the diary: a group that mainly socializes at home, a group that mainly socializes at a community center and a group that is more likely to socialize at public ‘third’ places. The respondents who did not record any interactions during the two days, are considered as a separate segment. Relationships between segment membership and personal and mobility characteristics were tested using cross-tabulations with chi-square tests and analyses of variance. The results suggest that both personal and mobility characteristics play an important role in social activity patterns of older adults. PMID:26343690

    INTRODUCTION Although the benefits of physical activity and exercise are widely acknowledged, many middle-aged and elderly individuals remain sedentary. This cross-sectional study aimed to identify the external and internal barriers to physical activity and exercise participation among middle-aged and elderly individuals, as well as identify any differences in these barriers between the two groups. METHODS Recruited individuals were categorised into either the middle-aged (age 45-59 years, n = 60) or elderly (age ≥ 60 years, n = 60) group. Data on demographics, anthropometry, as well as external and internal barriers to participation in physical activity and exercise were collected. RESULTS Analysis showed no significant differences in the total scores of all internal barriers between the two groups (p > 0.05). The total scores for most external barriers between the two groups also showed no significant differences (p > 0.05); only 'cost' (p = 0.045) and 'exercise interferes with social/family activities' (p = 0.011) showed significant differences. The most common external barriers among the middle-aged and elderly respondents were 'not enough time' (46.7% vs. 48.4%), 'no one to exercise with' (40.0% vs. 28.3%) and 'lack of facilities' (33.4% vs. 35.0%). The most common internal barriers for middle-aged respondents were 'too tired' (48.3%), 'already active enough' (38.3%), 'do not know how to do it' (36.7%) and 'too lazy' (36.7%), while those for elderly respondents were 'too tired' (51.7%), 'lack of motivation' (38.4%) and 'already active enough' (38.4%). CONCLUSION Middle-aged and elderly respondents presented with similar external and internal barriers to physical activity and exercise participation. These factors should be taken into account when healthcare policies are being designed and when interventions such as the provision of facilities to promote physical activity and exercise among older people are being considered.

  6. Learning science in small multi-age groups: the role of age composition

    2016-06-01

    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.

    The main aim of this study was to examine the effects of aging on event-related brain potentials (ERPs) associated with the automatic detection of unattended infrequent deviant and novel auditory stimuli (Mismatch Negativity, MMN) and with the orienting to these stimuli (P3a component), as well as the effects on ERPs associated with reorienting to relevant visual stimuli (Reorienting Negativity, RON). Participants were divided into three age groups: (1) Young: 21-29 years old; (2) Middle-aged: 51-64 years old; and (3) Old: 65-84 years old. They performed an auditory-visual distraction-attention task in which they were asked to attend to visual stimuli (Go, NoGo) and to ignore auditory stimuli (S: standard, D: deviant, N: novel). Reaction times (RTs) to Go visual stimuli were longer in old and middle-aged than in young participants. In addition, in all three age groups, longer RTs were found when Go visual stimuli were preceded by novel relative to deviant and standard auditory stimuli, indicating a distraction effect provoked by novel stimuli. ERP components were identified in the Novel minus Standard (N-S) and Deviant minus Standard (D-S) difference waveforms. In the N-S condition, MMN latency was significantly longer in middle-aged and old participants than in young participants, indicating a slowing of automatic detection of changes. The following results were observed in both difference waveforms: (1) the P3a component comprised two consecutive phases in all three age groups-an early-P3a (e-P3a) that may reflect the orienting response toward the irrelevant stimulation and a late-P3a (l-P3a) that may be a correlate of subsequent evaluation of the infrequent unexpected novel or deviant stimuli; (2) the e-P3a, l-P3a, and RON latencies were significantly longer in the Middle-aged and Old groups than in the Young group, indicating delay in the orienting response to and the subsequent evaluation of unattended auditory stimuli, and in the reorienting of attention to

    Working life in Germany is changing. The work force is ageing and the number of people available to the labour market will - from now on - shrink considerably. Prospectively, people will have to work longer; but still today, most people leave employment long before reaching official retirement age. What are the reasons for this? In this report, a conceptual framework and the German lidA Cohort Study are presented. The "lidA conceptual framework on work, age, health and work participation" visualises determinants of employment (11 "domains") in higher working age, e. g., "work", "health", "social status" and "life style". The framework reveals 4 key characteristics of withdrawal from work: leaving working life is the result of an interplay of different domains (complexity); (early) retirement is a process with in part early determinants in the life course (processual character); retirement has a strong individual component (individuality); retirement is embedded in a strong structural frame (structure). On the basis of this framework, the "lidA Cohort Study on work, age, health and work participation" (www.lida-studie.de) investigates long-term effects of work on health and work participation in the ageing work force in Germany. It is the only large study in Germany operationalising the concept of employability in a broad interdisciplinary approach. Employees subject to social security and born in 1959 or in 1965 will be interviewed (CAPI) every 3 years (N[wave 1]=6 585, N[wave 2]=4 244) and their data will be linked (where consented) with social security data covering employment history and with health insurance data. The study design ("Schaie's most efficient design") allows for a tri-factor model that isolates the impact of age, cohort and time. In 2014, the second wave was completed.

    2016-01-01

    This qualitative study critically explores the barriers experienced by diverse rural community stakeholders in facilitating environments that enable age-friendly social participation. Twenty-six semi-structured interviews were conducted across two rural Australian communities with stakeholders from local government, health, social care, and community organizations. Findings identify that rural community stakeholders face significant difficulties in securing resources for groups and activities catering to older adults, which subsequently impacts their capacity to undertake outreach to older adults. However, in discussing these issues, questions were raised in relation to whose responsibility it is to provide resources for community groups and organizations providing social initiatives and whose responsibility it is to engage isolated seniors. These findings provide a much-needed critical perspective on current age-friendly research by acknowledging the responsibilities of various macro-level social structures-different community-level organizations, local government, and policy in fostering environments to enable participation of diverse rural older adults.

    This paper presents differences by age in health care spending by type of expenditure and by source of funds through 1978. Use of health care services generally increases with age. The average health bill reached $2,026 for the aged in 1978, $764 for the intermediate age group, and $286 for the young. Biological, demographic, and policy factors determine each age group's share of health spending. Public funds financed over three-fifths of the health expenses of the aged, with Medicare and Medicaid together accounting for 58 percent. Most of the health expenses of the young age groups were paid by private sources. PMID:10309224

    Performance trends in breaststroke swimmers competing at world class level in pool competitions are well investigated for elite swimmers, but not for age group swimmers. This study investigated trends in participation, performance and sex difference in performance in a total of 35,143 (16,160 women and 18,983 men) age group breaststroke swimmers aged 25-29 to 95-99 years competing in the FINA World Masters Championships between 1986 and 2014. Trends in participation were analysed using linear regression analyses and trends in performance were investigated using mixed-effects regression analyses with sex, distance and calendar year as fixed variables. Women and men improved performance in all age groups. For age groups 25-29 to 85-89 years, men were faster than women. For age groups 90-94 to 95-99 years, men were not faster than women. Sex and distance showed a significant interaction for all distances in age groups 25-29 to 80-84 years. In 50 m, women reduced the gap to men in age groups 40-44 to 70-74 years and in 100 m and 200 m, women reduced the gap in age groups 50-54 to 60-64 years. In summary, (i) women and men improved performance in all race distances and in all age groups, (ii) men were faster than women from 25 to 89 years, but not from 90 to 99 years, and (iii), women reduced the gap to men between ~40 and ~75 years, but not in younger (<40 years) or older (>75 years) age groups. Based on these findings for a time period of nearly 30 years, we may assume a further increase in participation and a further improvement in performance in the near future in age group breaststroke swimmers competing at world class level.

    The Jackson Heart Study (JHS) convened focus groups to engage the community in dialogue on participation in the National, Heart, Lung and Blood Institute's Candidate Gene Resource (CARe) project. CARe, a genome wide association and candidate gene study, required the release of participant phenotypic and genotypic data with storage at NIH for widespread distribution to qualified researchers. The authors wanted to assess the willingness of an African American community to participate in the genetics research, given the past history of bioethical misconduct in ethnic minority communities. The discussion produced the following specific issues of interest: reasons for participants' interest in genetics research; participants' knowledge about the JHS; and participants' knowledge about genetics research and its advantages and disadvantages. Training on genetic issues was also developed for the JHS community and staff.

    A retrospective analysis of 35 patients aged 2 to 20 years who were seen at the District of Columbia General Hospital and Howard University Hospital over a three-year period (1984 to 1986) was performed. All patients were operated on with a preoperative diagnosis of acute appendicitis. A normal appendix was found in 17 percent of patients, of which the majority was adolescent girls. Of those patients with acute appendicitis, 41 percent had perforated appendices, and one half of these were judged to be complicated. At diagnosis or at reoperation, one half of the patients were maintained on single-antibiotic therapy, the other half were maintained on triple-antibiotic therapy. The average hospital stay was 26.6 days, with no significant difference between those patients on single- or triple-antibiotic coverage. The average hospital stay for patients with uncomplicated appendicitis was six days. PMID:3385787

    Adherence to physical activity and dietary interventions is a common challenge. Interventions that use group cohesion strategies show promise for increasing adherence, but have not been tested among women of color. The purpose of this study was to determine whether dimensions of group cohesion mediate the association between intervention condition and attendance within a community physical activity program for women of color. African American and Hispanic or Latina women (N=310) completed measurements at baseline and post-intervention and participated in a social cohesion intervention to improve physical activity and dietary habits. Women were assigned to a physical activity or fruit and vegetable intervention group. Social and task cohesion was measured using the Physical Activity Group Environment Questionnaire (PAGE-Q). Attendance was recorded at each of six intervention sessions. Women were generally middle-age (M age = 46.4 years, SD=9.1) and obese (M BMI = 34.4 kg/m2, SD=7.7). The estimate of the mediated effect was significant for all group cohesion constructs, indicating both task constructs—attraction to the group’s task (SE=0.096, CI: −0.599 to −0.221) and group integration around the task (SE=0.060, CI: −0.092 to −0.328)—and social constructs—attraction to the group’s social aspects (SE=0.046, CI: −0.546 to −0.366) and group integration around social aspects (SE=0.046, CI: −0.546 to −0.366)—significantly mediated the association between group assignment and attendance. Both task and social constructs are important to improve attendance in health promotion interventions for women of color. PMID:21826476

    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.

    Qualitative researchers attempting to protect the identities of their research participants now face a multitude of new challenges due to the wealth of information once considered private but now readily accessible online. We will draw on our research with family members of people with severe brain injury to discuss these challenges in relation to three areas: participant engagement with the mass media, the availability of court transcripts online, and participants’ use of social media. We suggest strategies for managing these challenges via disguise, refining informed consent, and discussion with interviewees. In the context of a largely theoretical literature on anonymization, this article offers concrete examples of the dilemmas we faced and will be of illustrative use to other researchers confronting similar challenges.

  1. Exploring the Experience of Nursing Home Residents Participation in a Hope-Focused Group

    Moore, Sharon L.; Hall, Susan E.

    2014-01-01

    A qualitative intervention was used to explore how older adults living in a long-term care environment (nursing home) understand hope and experience being participants in a group in which a hope intervention was carried out. A group project in which each session focused intentionally on a hope strategy was carried out with a convenience sample of 10 women (ages 75–99) who were members of an existing group. Data were analyzed using thematic analysis of the interviews (conducted before the group intervention was carried out and again at the end), field notes, and collaborative conversations regarding emerging themes. Findings from this study suggest that hope is not static and that it can change over time in response to one's situations and circumstances. Also evident in this study is the potential for using a group process in long-term care to foster hope in an intentional way to make it more visible in the lives of the residents and their environment suggesting that one is “never too old for hope.” PMID:24551450

    A prospective study was conducted to assess the long-term impact of attending a support group on the prevalence of psychological morbidity in patients with breast cancer before and after 1-year participation in the Iranian breast cancer support group. Psychological morbidity was measured using the hospital anxiety and depression scale (HADS). In addition, qualitative data were collected to throw some lights on the topic. All current members of the three Iranian breast cancer support groups (n=56) were interviewed. The mean age of patients was 45.4 (S.D.=9.2) years, most were married (n=46, 82%), and 54% of patients (n=30) were diagnosed as having breast cancer from 1 to 5 years ago. While at baseline 16 patients (29%) scored high on the anxiety sub-scale and eight patients (14%) scored high on the depression sub-scale, at follow-up only two patients (2%) were likely experiencing severe anxiety symptoms and there were no patients with probable severely depressed mood. Comparing anxiety and depression at baseline and follow-up, there was a statistically significant difference between baseline and follow-up anxiety (P=0.03) and depression (P=0.008) scores. Analysis of the qualitative data indicated that the group involvement was the most important factor that contributed to the patients' improved psychological well-being. The findings of this prospective study suggest that participation in cancer support groups could have a long-term effect in reducing anxiety and depression in breast cancer survivors.

    2014-07-01

    The number of people surviving until old age has been increasing worldwide. Reduction in fertility and mortality have resulted in increasing survival of populations to later life. This study examines the mortality trends among the three main ethnic groups in Malaysia, namely; the Malays, Chinese and Indians for four important age groups (adolescents, adults, middle age and elderly) for both gender. Since the data on mortality rates in Malaysia is only available in age groups such as 1-5, 5-9, 10-14, 15-19 and so on, hence some distribution or interpolation method was essential to expand it to the individual ages. In the study, the Heligman and Pollard model will be used to expand the mortality rates from the age groups to the individual ages. It was found that decreasing trend in all age groups and ethnic groups. Female mortality is significantly lower than male mortality, and the difference may be increasing. Also the mortality rates for females are different than that for males in all ethnic groups, and the difference is generally increasing until it reaches its peak at the oldest age category. Due to the decreasing trend of mortality rates, the government needs to plan for health program to support more elderly people in the coming years.

    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.

    2007-01-01

    Almost all patient-centered research is dependent on voluntary participation by participants. Many forces, however, act to either encourage or inhibit people from deciding to participate. This study explored adolescents' with type 1 diabetes and their parents' reasons for participating in a research study. We recruited adolescents with type 1 diabetes mellitus and their parents to participate in a focus group study. Qualitative analysis of the focus group data followed a set procedure: (a) audio review, (b) reading through transcriptions, (c) discussions among investigators regarding key elements of participants' perceptions, (d) determination of conceptual themes, and (e) assignment of relevant responses to appropriate thematic constructs. The 10 focus groups involved 59 participants. The three major themes that developed were giving and receiving, desire for peer socialization, and need for validation. Themes captured the reasons adolescents with type 1 diabetes and their parents decided to participate in this research. A better understanding of why people participate in research may help us to meet their needs and desires more completely. Designing research to meet these reasons will have the dual affect of increasing participation while also better serving those who choose to be studied.

    Increasing the length of participation in alcohol and drug treatment is associated with improved outcome. The present studies were designed to increase the number of individuals who participate in outpatient aftercare group therapy following completion of inpatient treatment. In Study 1, 22 participants who were assigned to attend a session of aftercare group during inpatient treatment were not more likely to participate in outpatient aftercare than those 19 who received a placebo treatment during inpatient treatment. In Study 2, 13 clients assigned a more intensive treatment, receiving aftercare orientation and signing a treatment contract, were compared with a group of 13 given placebo treatment; however, again there was no significant difference in outpatient participation in aftercare.

    2016-01-01

    ABSTRACT The aim of this qualitative study was to gain an understanding of what people who use wheeled mobility devices (WMDs; e.g., manual and power wheelchairs, and scooters) identify as environmental barriers to community participation in cold weather climates, and to explore recommendations to overcome environmental barriers to community participation. Researchers conducted an online asynchronous focus group that spanned seven days, with eight individuals who use WMDs. Each day, participants were asked to respond to a moderator-provided question, and to engage with one another around the topic area. The researchers analyzed the verbatim data using an inductive content-analysis approach. Four categories emerged from the data: (1) winter barriers to community participation; (2) life resumes in spring and summer; (3) change requires awareness, education, and advocacy; and (4) winter participation is a right. Participants confirmed that it is a collective responsibility to ensure that WMD users are able to participate in the community throughout the seasons. PMID:26295488

    Given the important role of treatment attendance as an indicator of program implementation and as a potential moderator of program effectiveness, this study sought to develop useful indicators of attendance for evidence-based practices. The current study examined consumer attendance patterns in a randomized controlled trial comparing illness management and recovery (n=60) to a problem solving control condition (n=58). Associations were examined between consumer clinical indicators, demographics, and level of recovery and indices of attendance. Attendance was poor, but comparable to rates found in many other studies. Four indicators of attendance (percent sessions attended, time enrolled, periods of attendance, and longest period of attendance) were highly inter-related and were more sensitive to baseline differences than a traditional approach of dichotomizing participants into "attenders" and "non-attenders." Older age, lower hostility, fewer psychotic symptoms, and more education were associated with higher group attendance in both treatment conditions; the client-reported illness management and recovery scale was associated with attendance in the control group. Indicators of attendance were an advancement over dichotomous classification. Strategies to increase attendance are still needed, particularly for younger consumers with greater positive symptoms.

    This study aims to verify the mediation effect of recovery resilience according to the relation between Senior Citizen Community Center (SCCC) elderly users' participation in exercise rehabilitation programs and their successful aging. Toward that end, 400 65-yr or older participants and non-participants in SCCCs' exercise rehabilitation programs, living in Incheon, were sampled. Of their answered questionnaires, 35 copies which were deemed low-reliability, duplicated, and inadequately specified were excluded from the analysis. And, the other data were coded through computers, and underwent a descriptive statistical analysis (DSA) and a standard multiple regression analysis (SMRA) using Windows SPSS/PC+21.0 Version statistical program. Thus it was firstly found that elderly people's participation or non-participation in exercise rehabilitation programs partially influenced their recovery resilience and successful aging. The participants group, compared with the non-participants group, had greater recovery resilience and experienced successful aging. Second, the relation between the degree of participation in exercise rehabilitation programs, recovery resilience and successful aging revealed that the longer and the more frequent the participation in exercise rehabilitation programs was, the greater the recovery resilience was and the more successful aging was. Third, the verification of the mediation effect of recovery resilience in the relation between the program participation degree and the successful aging revealed that, compared with those of the model of direct effects of independent variables and dependent variables, the recovery resilience-mediated model's verification power and explanation power were greater.

    Introduction Maximum bite force (MBF) is the maximum force performed by the subject on the fragmentation of food, directly related with the mastication and determined by many factors. Objective Analyze the MBF of subjects according to age groups. Methods One hundred individuals from the city of São Paulo were equally divided according to age groups and gender. Each individual submitted to a myotherapy evaluation composed of anthropometric measurements of height and weight to obtain body mass index (BMI), using a tape and a digital scale (Magna, G-life, São Paulo), and a dental condition and maximum bite force evaluation, using a digital dynamometer model DDK/M (Kratos, São Paulo, Brazil), on Newton scale. The dental and bite force evaluations were monitored by a professional from the area. Analysis of variance was used with MBF as a dependent variable, age group and gender as random factors, and BMI as a control variable. Results Till the end of adolescence, it was possible to observe a decrease in MBF in both sexes, with the male force greater than the female force. In young adults, the female force became greater the males, then decreased in adulthood. There was no correlation between MBF and BMI. Conclusion There are MBF variations that characterizes the human development stages, according to age groups. PMID:25992105

    PubMed

    Verthein, U; Raschke, P

    1999-12-01

    To evaluate the importance of self-help groups and the patients' readiness to participate in such groups a sample of 675 methadone patients in Hamburg was asked by means of questionnaires. 43% of the patients had heard of self-help groups. One quarter of them (10% of the whole sample) had participated in self-help groups at some time. The greatest importance of self-help organisations is attached to a representation of the interests of methadone patients to improve their overall situation. Another important purpose of self-help groups is seen in getting help for legal, financial and social problems. Getting in contact with other clients or offering breakfast/lunch, washing clothes or shower facilities etc. is not evaluated as an important task for self-help organisations. Patients who are working on a regular basis and living in stable conditions are less interested in participating in self-help groups. Thus, the participants in self-help groups can hardly benefit from the experiences of the socially better integrated methadone patients.

    For years, public discourse in science education, technology, and policy-making has focused on the "leaky pipeline" problem: the observation that fewer women than men enter science, technology, engineering, and mathematics fields and more women than men leave. Less attention has focused on experimentally testing solutions to this problem. We report an experiment investigating one solution: we created "microenvironments" (small groups) in engineering with varying proportions of women to identify which environment increases motivation and participation, and whether outcomes depend on students' academic stage. Female engineering students were randomly assigned to one of three engineering groups of varying sex composition: 75% women, 50% women, or 25% women. For first-years, group composition had a large effect: women in female-majority and sex-parity groups felt less anxious than women in female-minority groups. However, among advanced students, sex composition had no effect on anxiety. Importantly, group composition significantly affected verbal participation, regardless of women's academic seniority: women participated more in female-majority groups than sex-parity or female-minority groups. Additionally, when assigned to female-minority groups, women who harbored implicit masculine stereotypes about engineering reported less confidence and engineering career aspirations. However, in sex-parity and female-majority groups, confidence and career aspirations remained high regardless of implicit stereotypes. These data suggest that creating small groups with high proportions of women in otherwise male-dominated fields is one way to keep women engaged and aspiring toward engineering careers. Although sex parity works sometimes, it is insufficient to boost women's verbal participation in group work, which often affects learning and mastery. PMID:25848061

    Purpose: Cancer survivors in their adolescent and young adult (AYA) years are an understudied population, possibly in part because of the high effort required to recruit them into research studies. The aim of this paper is to describe the specific recruitment strategies used in four studies recruiting AYA-aged female cancer survivors and to identify the highest yielding approaches. We also discuss challenges and recommendations. Methods: We recruited AYA-aged female cancer survivors for two studies conducted locally and two conducted nationally. Recruitment strategies included outreach and referral via: healthcare providers and clinics; social media and the internet; community and word of mouth; and a national fertility information hotline. We calculated the yield of each recruitment approach for the local and national studies by comparing the number that participated to the number of potential participants. Results: We recruited a total of 534 participants into four research studies. Seventy-one percent were diagnosed as young adults and 61% were within 3 years of their cancer diagnosis. The highest-yielding local recruitment strategy was healthcare provider and clinic referral. Nationally, social media and internet outreach yielded the highest rate of participation. Overall, internet-based recruitment resulted in the highest number and yield of participants. Conclusion: Our results suggest that outreach through social media and the internet are effective approaches to recruiting AYA-aged female cancer survivors. Forging collaborative relationships with survivor advocacy groups' members and healthcare providers also proved beneficial.

    With increasing age, youth with disabilities are at risk for decreased participation in leisure activities, a key component for physical and mental health. This prospective study describes changes in leisure participation and leisure preferences from school-age to adolescence in children with cerebral palsy (CP). Participants were recruited at school-age (6-12 years) for a study on participation and reassessed for a second study on adolescents (12-19 years) if >12 years. Thirty-eight children (24 males) with CP who could actively participate in the completion of the Children's Assessment of Participation and Enjoyment (CAPE) and the Preferences for Activities of Children (PAC) comprised the sample. Average time between assessments was 5.0 ± 1.3 years. Most children were ambulatory (32/38 Gross Motor Function Classification System I-II). In addition to the CAPE and PAC, children were evaluated using the Gross Motor Function Measure-66 and parents completed a socio-demographic questionnaire. Paired t-tests revealed a significant decline in leisure participation diversity and intensity (CAPE) for recreation (p<.0001), skill-based (p<.0001) and self-improvement (p<.05) activities, whereas social participation remained stable (p>.05). Diversity of active-physical activities increased modestly (p=.06) although intensity of participation in this activity domain decreased (p=.003). There was also a decline in enjoyment of leisure activities. Preferences for these leisure activities remained unchanged between school-age and adolescence, except for recreational activities. Gender, maternal education, family income and gross motor ability were not related to differences in CAPE/PAC scores with increasing age. Findings suggest that over time, children with CP's participation in leisure activities diminishes, which is of concern to their functioning and well-being. Parents may be more involved in early childhood in facilitating participation whereas in adolescence, youth may

    Studies of temperament profiles in patients with mental disorders mostly focus on emotionality-related traits, although mental illness symptoms include emotional and nonemotional aspects of behavioral regulation. This study investigates relationships between 12 temperament traits (9 nonemotionality and 3 emotionality related) measured by the Structure of Temperament Questionnaire and four groups of clinical symptoms (depression, anxiety, antisociality, and dominance-mania) measured by the Personality Assessment Inventory. The study further examines age differences in relationships among clinical symptoms and temperament traits. Intake records of 335 outpatients and clients divided into four age groups (18-25, 26-45, 46-65, and 66-85) showed no significant age differences on depression scales; however, the youngest group had significantly higher scores on Anxiety, Antisocial Behavior, Dominance, and Thought Disorders scales. Correlations between Personality Assessment Inventory and Structure of Temperament Questionnaire scales were consistent with Diagnostic and Statistical Manual of Mental Disorders, 4th Edition, descriptors showing strong concurrent validity. Several age differences on temperament scales are also reported. Results show the benefits of differentiation between physical, social-verbal, and mental aspects of activities, as well as differentiation between dynamical, orientational, and energetic aspects in studying mental illness and temperament.

    This study analyzes the effect on levels of patient anxiety and depression of a partner joining a cardiac rehabilitation program support group, also taking into account the sex of the patient. The study was undertaken using a two-group comparison design with pre-and post-test measures in non-equivalent groups. The sample comprised patients in the cardiac rehabilitation program (CRP) at the Ramón y Cajal Hospital, Madrid (Spain). Analysis of covariance (ANCOVA) showed direct effects of sex and partner participation in support groups on the anxiety trait. Similarly, interaction effects were observed between the sex variable and partner participation. These results indicate the pertinence of designing separate groups for patients and partners.

    Background Participation in daily activities during childhood is an important aspect for health and social development. Objectives This study was designed to investigate the participation of children with cerebral palsy aged 8 to 14 years, and their normal peers. Patients and Methods In this cross-sectional study, 30 children with cerebral palsy, and 30 normal children were selected via the non-probability convenience sampling. Their participation was evaluated with children’s assessment of participation and enjoyment (CAPE) through interviews. Results Significant differences were found between the means of the two groups regarding the diversity, intensity, overall participation (P = 0.000) and all types of the activities except the recreational activities. The children with cerebral palsy took part in the skill-based activities and overall activities individually compared to the normal peers. The children with cerebral palsy, in comparison with their normal peers, often performed most of the activities inside the house. The main effect of gender and the interaction between gender and groups were not statistically significant in any of the variables of the CAPE test. Conclusions Physical disability can influence the children’s daily activities and socialization. Understanding the participation of physically disabled children can help health care professionals in designing and introducing appropriate treatment according to their needs. PMID:27617075

    Purpose. The purpose of this study was to explore the perceptions of people with multiple sclerosis of a community based, group exercise programme. Method. A pragmatic programme evaluation approach using qualitative research design was adopted. Focus groups were used to gather data from 14 participants who had taken part in a RCT of community based exercise interventions for PwMS who used at most a stick to walk outdoors. Data were transcribed verbatim and thematic analysis was used to first identify categories and then to group them into themes. Results. Three themes emerged, psychological benefits, physical benefits, and knowledge gained. The psychological benefits included the role of the group as a social and motivational factor, empowerment, confidence, hope, sense of achievement, and pride. Physical benefits were improved energy and reduced fatigue and improved ability and participation. Knowledge gained caused a shift from thoughts that exercise might do harm, to sufficient knowledge that would give participants confidence to exercise themselves. The role of the group was a key element in the positive outcomes. Conclusions. The qualitative analysis supports the findings of the main trial confirming positive effects of community exercise interventions by reducing the impact of MS and fatigue and improving participation.

    Klauke, Karin; de Haan, Gerald

    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.

    During the last 4 decades, a rapid increase has occurred in the number of survey-based and epidemiological studies of the health profiles of adults in general and of the causes of disparities between majority and minority Americans in particular. According to these studies, healthful aging consists of the absence of disease, or at least of the most serious preventable diseases and their consequences, and findings consistently reveal serious African American and Hispanic disadvantages in terms of healthful aging. We (1) briefly review conceptual and operational definitions of race and Hispanic ethnicity, (2) summarize how ethnicity-based differentials in health are related to social structures, and (3) emphasize the importance of attention to the economic, political, and institutional factors that perpetuate poverty and undermine healthful aging among certain groups.

    Social participation becomes particularly important in middle childhood, as it contributes towards the acquisition and development of critical life skills such as developing friendships and a sense of belonging. However, only limited literature is available on the impact of communication difficulties on social participation in middle childhood. This study compared the participation patterns of school-age children with and without physical disabilities and complex communication needs in extracurricular activities. Participants included five children between 6-9 years of age with moderate-severe physical disability and complex communication needs, and five matched peers. Findings showed that children with physical disability and complex communication needs engaged in activities with reduced variety, lower frequency, fewer partners and in limited venues, but reported higher levels of enjoyment and preference for activity participation, than their matched peers. These children also had fewer same-aged friends, but more paid workers in their social circle. This small-scale descriptive study provides some preliminary evidence about the impact of severe communication difficulties on participation and socialization. PMID:22008032

    [Purpose] This study investigated the relationship between activity limitation and participation restriction in school-aged children with cerebral palsy. [Subjects and Methods] Data were collected from 109 children with cerebral palsy aged 6–12 years. Activity limitations were assessed by using functional classification systems including the Korean-Gross Motor Function Classification System, the Korean-Manual Ability Classification System, and the Korean-Communication Function Classification System. Participation restriction was measured using the Korean-Frequency of Participation Questionnaire. Physical or occupational therapists and parents collected the data. [Results] All levels of the functional classification systems were significantly negatively correlated with Korean-Frequency of Participation Questionnaire ratings (r= −0.382 to −0.477). The Korean-Frequency of Participation Questionnaire ratings differed significantly with respect to the functional classification systems; in particular, the differences in the ratings of levels I and V were significant. The Korean-Communication Function Classification System and Korean-Gross Motor Function Classification System were significant predictors of participation, explaining 26.5% of the variance. [Conclusion] Intervention programs are required to promote communication skills and gross motor ability in order to improve the participation of children with cerebral palsy. PMID:26357445

  11. A Provably Secure Revocable ID-Based Authenticated Group Key Exchange Protocol with Identifying Malicious Participants

    PubMed Central

    Tsai, Tung-Tso

    2014-01-01

    The existence of malicious participants is a major threat for authenticated group key exchange (AGKE) protocols. Typically, there are two detecting ways (passive and active) to resist malicious participants in AGKE protocols. In 2012, the revocable identity- (ID-) based public key system (R-IDPKS) was proposed to solve the revocation problem in the ID-based public key system (IDPKS). Afterwards, based on the R-IDPKS, Wu et al. proposed a revocable ID-based AGKE (RID-AGKE) protocol, which adopted a passive detecting way to resist malicious participants. However, it needs three rounds and cannot identify malicious participants. In this paper, we fuse a noninteractive confirmed computation technique to propose the first two-round RID-AGKE protocol with identifying malicious participants, which is an active detecting way. We demonstrate that our protocol is a provably secure AGKE protocol with forward secrecy and can identify malicious participants. When compared with the recently proposed ID/RID-AGKE protocols, our protocol possesses better performance and more robust security properties. PMID:24991641

    Abstract The concept of using single criterion of normal blood pressure with systolic blood pressure (SBP) < 140 mmHg and diastolic blood pressure (DBP) < 90 mmHg for all ages is still disputable. The aim of the study is to identify the cutoff value of normotension in different age and sex groups. Totally, 127,922 (63,724 men and 64,198 women) were enrolled for the analysis. Finally, four fifths of them were randomly selected as the study group and the other one fifths as the validation group. Due the tight relationship with comorbidities from cardiovascular disease (CVD), metabolic syndrome (MetS) was used as a surrogate to replace the actual cardiovascular outcomes in the younger subjects. For SBP, MetS predicted by our equation had a sensitivity of 55% and specificity of 67% in males and 65%, 83% in females, respectively. At the same time, they are 61%, 73% in males and 73%, 86% in females for DBP, respectively. These sensitivity, specificity, odds ratio, and area under the receiver operating characteristic curve from our equations are all better than those derived from the criteria of 140/90 or 130/85 mmHg in both genders. By using the presence of MetS as the surrogate of CVD, the regression equations between SBP, DBP, and age were built in both genders. These new criteria are proved to have better sensitivity and specificity for MetS than either 140/90 or 130/85 mmHg. These simple equations should be used in clinical settings for early prevention of CVD. PMID:27057846

    2016-09-01

    The main purpose of the present study was to understand the subjective experience of patients adjusting to cancer by focusing on how that experience might be affected by participating in a psychodramatic group intervention. In-depth interviews using an interpretative-phenomenological approach were conducted with eight cancer patients involved in a psychodrama group. Four key themes were identified: (1) outside and inside relationships; (2) identities: nurturing other selves; (3) a feelings' gym: performing the internal world; and (4) many ends: mourning death and dying. Participation in cancer group using a psychodramatic approach provided positive results. In detail, the group setting: (1) favoured relationships in which it was possible to freely express oneself and (2) empowered patients in their feelings of being able to give and receive help; the psychodramatic approach: (1) supported the physical mobilisation of sense of agency and (2) permitted to deal with the grieving process. Cancer healthcare pathways would benefit from psychotherapeutic programmes using a similar approach, since psychodrama by actively involving body seems to works on areas that are often underwhelmed by other approaches, such as (i.e., physical mobilisation, body engagement, grieving adjustment). Psychodrama supports patients to achieve insights into their own possibilities to actively participate in their own life situations despite having cancer and undergoing treatment for it.

    A detailed experimental and DFT study of the S to N alkyl migration of substituted S-(1(3H)-isobenzofuranon-3-yl)isothiuronium bromide to N,N'-dimethyl-N-(3-oxo-1,3-dihydro-2-benzofuran-1-yl)thiourea provided evidence for the existence of an unusual double displacement mechanism involving two consecutive back-side S(N)2 reactions where a carboxylate anion has a crucial role both as a leaving group as well as an internal nucleophile. The thiazetidine zwitterionic species that is involved in this mechanism as an intermediate was characterized by infrared multiphoton dissociation spectroscopy and was trapped with methyl iodide. It was found that the intermediate has a structure of a free ion pair. The double-displacement mechanism can be considered as a new type of inverse lactone neighboring group participation.

    Cardiometabolic diseases affect underserved groups disparately. Participation in health checks is also lower, widening health inequalities in society. Two-stage screening (non-invasive health risk assessment (HRA) and GP consultations for high-risk individuals) seems cost-effective, provided that drop-out rates are low in both steps. We aimed to explore the process of decision-making regarding HRA participation among underserved groups (45-70 y): native Dutch with a lower socioeconomic status (SES), Turkish, Moroccan, and Surinamese participants. We conducted a cross-sectional questionnaire study. The questionnaire comprised the following determinants: a self-formulated first reaction, a structured set of predefined determinants, and the most important barrier(s) and facilitator(s) for HRA completion. We used univariable and (stepwise) multivariate logistic regression analyses to assess which determinants were associated with HRA completion. Of the 892 participants in the questionnaire, 78% (n = 696) also completed the HRA. Moroccans and patients from GP practices with a predominantly non-Western population less often completed the HRA. A lower SES score, wanting to know one's risk, not remembering receiving the invitation (thus requiring a phone call), fear of the test result and/or adjusting lifestyle, perceived control of staying healthy, wanting to participate, and perceiving no barriers were associated with completing the HRA. We conclude that our 'hard-to-reach' population may not be unwilling to participate in the HRA. A more comprehensive approach, involving key figures within a community informing people about and providing help completing the HRA, would possibly be more suitable. Efforts should be particularly targeted at the less acculturated immigrants with an external locus of control. PMID:27413659

    How can you more effectively lead your group? In today's world of rapid technological and social change, where Thriving on Chaos is the best-selling management book, group work is not a luxury, but a necessity. Although some employees naturally prefer working alone, we all must function effectively in group settings. To lead a group well, the leader needs to be sensitive to three critical variables: participation, power, and problem-solving. Balancing these processes becomes the key to effective performance. The leader must pay close attention to what is happening within the group and make specific interventions to more effectively distribute the skills and energies of the members. Making every group member a significant contributor takes skill but results in more accurate decisions and greater commitment. The group leader is the facilitator, charged with managing the problem-solving process and leading the group to the most productive, objective outcome. This article supplies many practical, corrective strategies for moving your group in a more positive direction.

    Scurvy is caused by prolonged severe dietary deficiency of vitamin C. Being rare as compared to other nutritional deficiencies, it is seldom suspected and this frequently leads to delayed recognition of this disorder. Children with abnormal dietary habits, mental illness or physical disabilities are prone to develop this disease. The disease spectrum of scurvy is quite varied and includes dermatological, dental, bone and systemic manifestations. Subperiosteal hematoma, ring epiphysis, metaphyseal white line and rarefaction zone along with epiphyseal slips are common radiological findings. High index of suspicion, detailed history and bilateral limb radiographs aids physician in diagnosing this eternal masquerader. We searched Pubmed for recent literature (2009-2014) with search terms "scurvy" "vitamin C deficiency" "ascorbic acid deficiency" "scurvy and children" "scurvy and pediatric age group". There were a total of 36 articles relevant to pediatric scurvy in children (7 reviews and 29 case reports) which were retrieved. The review briefly recapitulates the role of vitamin C, the various disease manifestations and the treatment of scurvy to create awareness of the disease which still is reported from our country, although sporadically. The recent advances related to scurvy and its management in pediatric age group are also incorporated. PMID:25983516

    In this study we explored the experience of competing in the Senior Games and the resultant contributions to the successful aging of older adults. We used in-depth interviews with older adults who participated in the National Senior Games. Analysis of the data produced five central themes: (a) perseverance, (b) career development and significant effort, (c) personal and social benefits, (d) unique ethos, and (e) identification as a senior athlete. We found that participating in the Senior Games as a form of serious leisure enhanced the well-being of older adults and could be utilized as a means by which to maintain a healthy lifestyle.

    Objectives To explore factors influencing the likelihood of antenatal vaccine acceptance of both routine UK antenatal vaccines (influenza and pertussis) and a hypothetical group B Streptococcus (GBS) vaccine in order to improve understanding of how to optimise antenatal immunisation acceptance, both in routine use and clinical trials. Setting An online survey distributed to women of childbearing age in the UK. Participants 1013 women aged 18–44 years in England, Scotland and Wales. Methods Data from an online survey conducted to gauge the attitudes of 1013 women of childbearing age in England, Scotland and Wales to antenatal vaccination against GBS were further analysed to determine the influence of socioeconomic status, parity and age on attitudes to GBS immunisation, using attitudes to influenza and pertussis vaccines as reference immunisations. Factors influencing likelihood of participation in a hypothetical GBS vaccine trial were also assessed. Results Women with children were more likely to know about each of the 3 conditions surveyed (GBS: 45% vs 26%, pertussis: 79% vs 63%, influenza: 66% vs 54%), to accept vaccination (GBS: 77% vs 65%, pertussis: 79% vs 70%, influenza: 78% vs 68%) and to consider taking part in vaccine trials (37% vs 27% for a hypothetical GBS vaccine tested in 500 pregnant women). For GBS, giving information about the condition significantly increased the number of respondents who reported that they would be likely to receive the vaccine. Health professionals were the most important reported source of information. Conclusions Increasing awareness about GBS, along with other key strategies, would be required to optimise the uptake of a routine vaccine, with a specific focus on informing women without previous children. More research specifically focusing on acceptability in pregnant women is required and, given the value attached to input from healthcare professionals, this group should be included in future studies.

    The purpose of this study was to interpret students' participation in terms of social and argumentation norms to improve understanding of social interaction in scientific argumentation. Therefore, the study sought to identify social and argumentation norms formed in group argumentation and to explore changes in students' participation as lessons progressed. Twelve lessons that included argumentation were delivered to 44 eighth graders in Korea. In each lesson, small group argumentation tasks were introduced after the teacher had explained the main concepts or after student-centred hands-on activities. We analysed argumentation in one focus group based on various data, including audiotaped and videotaped conversations, field notes and student interviews. In early lessons, discussions were always teacher-initiated and led by a high-achieving student, while other students rarely presented ideas. Moreover, students struggled to seek answers in a textbook and often used analogies and common sense to explain phenomena. They tended to accept others' opinions unquestioningly or ignore other low achievers' ideas in small group argumentation. In later lessons, we observed student-initiated and more equally distributed discussions, in which students were likely to make claims or statements actively based on experimental results and scientific knowledge. Along with these changes in discussion style, some students were seen to support the building of social norms and argumentation norms in a group. Also, performing tasks and receiving guidance from the teacher helped to build students' epistemological norms about scientific argumentation.

    SMART Recovery groups are cognitive-behaviorally oriented mutual support groups for individuals with addictions. The aim of the study was to assess the extent to which the quality of group facilitation, group cohesion and the use of between session homework activities contribute to self-rated use of cognitive-behavioral skills amongst group participants. Participants attending SMART Recovery groups in Australia completed a cross sectional survey (N=124). The survey included measures of cognitive and behavioral skill utilization, group cohesion, quality of group facilitation and a rating of how frequently participants leave group meetings with an achievable between session homework plan. On average, participants had been attending SMART Recovery meetings for 9 months. Participants were most likely to attend SMART Recovery for problematic alcohol use. Regression analyses indicated that group cohesion significantly predicted use of cognitive restructuring, but that only provision of homework at the end of each group session predicted self-reported behavioral activation. Both group cohesion and leaving a group with an achievable homework plan predicted participant use of cognitive behavioral skills. The concrete actions associated with homework activities may facilitate behavioral activation. There is a need for longitudinal research to examine the relationship between the utilization of cognitive and behavioral skills and participant outcomes (e.g. substance use, mental health) for people attending SMART Recovery groups.

    Tobacco cessation interventions developed for Alaska Native adolescents do not exist. This study employed focus group methodology to explore preferences for tobacco cessation interventions and barriers to participation among 49 Alaska Natives (61% female) with a mean age of 14.6 (SD = 1.6) who resided in western Alaska. Using content analysis, themes from the 12 focus groups were found to be consistent across village, gender, and age groups. Program location or site (e.g., away from the village, hunting, fishing), a group-based format, and inclusion of medication and personal stories were reported to be important attributes of cessation programs. Motivators to quit tobacco were the perceived adverse health effects of tobacco, improved self-image and appearance, and the potential to be a future role model as a non–tobacco user for family and friends. Parents were perceived as potentially supportive to the adolescent in quitting tobacco. The findings will be used to develop tobacco cessation programs for Alaska Native youth. PMID:18048549

    The objective of this study is to determine the influence of maternal health literacy and child's age on participation in social welfare programs benefiting children. In a longitudinal prospective cohort study of 560 Medicaid-eligible mother-infant dyads recruited in Philadelphia, maternal health literacy was assessed using the test of functional health literacy in adults (short version). Participation in social welfare programs [Temporary Assistance to Needy Families (TANF), Supplemental Nutrition Assistance Program (SNAP), Special Supplemental Nutrition Program for Women, Infants, and Children (WIC), child care subsidy, and public housing] was self-reported at child's birth, and at the 6, 12, 18, 24 month follow-up interviews. Generalized estimating equations quantified the strength of maternal health literacy as an estimator of program participation. The mothers were primarily African-Americans (83%), single (87%), with multiple children (62%). Nearly 24% of the mothers had inadequate or marginal health literacy. Children whose mothers had inadequate health literacy were less likely to receive child care subsidy (adjusted OR = 0.54, 95% CI 0.34-0.85) than children whose mothers had adequate health literacy. Health literacy was not a significant predictor for TANF, SNAP, WIC or housing assistance. The predicted probability for participation in all programs decreased from birth to 24 months. Most notably, predicted WIC participation declined rapidly after age one. During the first 24 months, mothers with inadequate health literacy could benefit from simplified or facilitated child care subsidy application processes. Targeted outreach and enrollment efforts conducted by social welfare programs need to take into account the changing needs of families as children age.

Six residents were interviewed. Themes emerging from discussions about their social interactions included: importance of family, fostering friendships with fellow residents, placement at dining room tables, multiple communication methods, and minimal social isolation and boredom. Excursions away from the RAC facility were favourite activities. Participants commonly were involved in leisure activities to be socially connected. Poor health, family, the RAC facility, staffing, transportation, and geography influenced their social interaction and participation in leisure activities. The use of new technologies and creative problem solving with staff are ways in which residents could enhance their social lives and remain engaged in leisure activities. PMID:24299253

    Scurvy is caused by prolonged severe dietary deficiency of vitamin C. Being rare as compared to other nutritional deficiencies, it is seldom suspected and this frequently leads to delayed recognition of this disorder. Children with abnormal dietary habits, mental illness or physical disabilities are prone to develop this disease. The disease spectrum of scurvy is quite varied and includes dermatological, dental, bone and systemic manifestations. Subperiosteal hematoma, ring epiphysis, metaphyseal white line and rarefaction zone along with epiphyseal slips are common radiological findings. High index of suspicion, detailed history and bilateral limb radiographs aids physician in diagnosing this eternal masquerader. We searched Pubmed for recent literature (2009–2014) with search terms “scurvy” “vitamin C deficiency” “ascorbic acid deficiency” “scurvy and children” “scurvy and pediatric age group”. There were a total of 36 articles relevant to pediatric scurvy in children (7 reviews and 29 case reports) which were retrieved. The review briefly recapitulates the role of vitamin C, the various disease manifestations and the treatment of scurvy to create awareness of the disease which still is reported from our country, although sporadically. The recent advances related to scurvy and its management in pediatric age group are also incorporated. PMID:25983516

    Developing motor competence and physical fitness can affect the maintenance of a sufficient level of physical activity in children and adolescents. This study assesses the relationship between motor competence and physical fitness from childhood through early adolescence. A cross-sectional sample of 194 participants from 4 to 16 years old were divided into three groups; 4-6 yr. (n=42, M age=5.2, SD 0.6), 11-12 yr. (n=58, M age=12.4, SD=0.3), and 15-16 yr. (n=94, M age=15.9, SD=0.4). To assess motor competence, each child completed the Movement Assessment Battery for Children (MABC). To measure physical fitness, three tasks (strength, speed, and endurance) were selected from the Test of Physical Fitness (TPF). To analyze the significance of the difference between the correlation coefficient in the three age groups (samples) (4-6, 11-12, and 15-16 yr.), Fischer r-to-z transformation was used. The correlation (Pearson's) between motor competence and physical fitness in the age groups was statistically higher for the youngest age groups (4-6 and 11-12 yr.) and the adolescent group (age 15-16). The differences between the two youngest age groups were not statistically significant. The results demonstrate that the correlation between motor competence and physical fitness decreases with age.

    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 5 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.

    Firefighters perform many tasks which require a high level of fitness and their personal safety may be compromised by the physiological aging process. The aim of the study was to evaluate strength (bench-press), power (countermovement jump), sprint (20 m) and endurance (with and without Self Contained Breathing Apparatus - S.C.B.A.) of 161 Italian firefighters recruits in relation to age groups (<25 yr; 26-30 yr; 31-35 yr; 36-40 yr; 41-42 yr). Descriptive statistics and an ANOVA were calculated to provide the physical fitness profile for each parameter and to assess differences (p < 0.05) among age groups. Anthropometric values showed an age-effect for height and BMI, while performances values showed statistical differences for strength, power, sprint tests and endurance test with S.C.B.A. Wearing the S.C.B.A., 14% of all recruits failed to complete the endurance test. We propose that the firefighters should participate in an assessment of work capacity and specific fitness programs aimed to maintain an optimal fitness level for all ages.

    BACKGROUND/OBJECTIVES South Korean's sodium consumption level is more than twice the upper limit level suggested by the WHO. Steep increases in the prevalence of hypertension and cardiovascular disease in Korea necessitate more effective sodium reduction programs. This study was conducted in order to compare sodium intake-related eating behaviors and key psychosocial factors according to age group and gender. SUBJECTS/METHODS Using an online survey, a total of 1,564 adults (20-59 years old) considered to be geographically representative of South Korea were recruited and surveyed. The major outcomes were perceived behaviors, knowledge, intentions, and self-efficacy related to sodium intake. RESULTS The results show that perceived behavior and level of self-efficacy related to low sodium consumption differed by age and gender. Female participants showed better behavior and intention towards low sodium intake than male counterparts. Young participants in their 20s showed the lowest intention to change their current sodium intake as well as lowest self-efficacy measures. CONCLUSIONS Future sodium reduction interventions should be developed with tailored messages targeting different age and gender groups. Specifically, interventions can be planned and implemented at the college level or for workers in their early career to increase their intention and self-efficacy as a means of preventing future health complications associated with high sodium intake.

    Dental services utilization in the past 12 months was compared across population-based samples of African-American, Navajo, Lakota, Hispanic, and White adults participating in the WHO International Collaborative Study of Oral Health Outcomes (ICS-II) at USA research locations. Bivariate results revealed that ethnic minority groups in both age cohorts reported significantly fewer dental visits in the past 12 months compared with White adults. When dentate status was controlled for, age cohort differences were not significant in Baltimore (African-American and White) and San Antonio (Hispanic and White) research locations. In contrast, older Native Americans (65-74 years) reported visiting the dentist significantly less often compared with their middle-aged (35-44 years) counterparts. Multivariate results indicated that generalizable variables were associated with dental contact in every ICS-II USA ethnic group (i.e., dentate, usual source of dental care, oral pain). Among the diverse ethnic groups, other determinants presented a varied pattern of risk factors for underutilizing dental care. Information on ethnic-specific risk factors can be used to design culturally appropriate and acceptable oral health promotion programs. Generalizable risk factors across ethnic groups inform oral health policy-makers about changing national priorities for promoting oral health. PMID:9549991

    2012-01-01

    Background We present concept, study protocol and selected baseline data of the Longitudinal Urban Cohort Ageing Study (LUCAS) in Germany. LUCAS is a long-running cohort study of community-dwelling seniors complemented by specific studies of geriatric patients or diseases. Aims were to (1) Describe individual ageing trajectories in a metropolitan setting, documenting changes in functional status, the onset of frailty, disability and need of care; (2) Find determinants of healthy ageing; (3) Assess long-term effects of specific health promotion interventions; (4) Produce results for health care planning for fit, pre-frail, frail and disabled elderly persons; (5) Set up a framework for embedded studies to investigate various hypotheses in specific subgroups of elderly. Methods/Design In 2000, twenty-one general practitioners (GPs) were recruited in the Hamburg metropolitan area; they generated lists of all their patients 60 years and older. Persons not terminally ill, without daily need of assistance or professional care were eligible. Of these, n = 3,326 (48 %) agreed to participate and completed a small (baseline) and an extensive health questionnaire (wave 1). In 2007/2008, a re-recruitment took place including 2,012 participants: 743 men, 1,269 women (647 deaths, 197 losses, 470 declined further participation). In 2009/2010 n = 1,627 returned the questionnaire (90 deaths, 47 losses, 248 declined further participation) resulting in a good participation rate over ten years with limited and quantified dropouts. Presently, follow-up data from 2007/2008 (wave 2) and 2009/2010 (wave 3) are available. Data wave 4 is due in 2011/2012, and the project will be continued until 2013. Information on survival and need of nursing care was collected continuously and cross-checked against official records. We used Fisher’s exact test and t-tests. The study served repeatedly to evaluate health promotion interventions and concepts. Discussion LUCAS shows that a cohort

    Objectives To estimate the prevalence of dermatological disease in aged care facilities, and the relationship between cognitive or physical disability and significant disease. Setting 2 large aged care facilities in Auckland, New Zealand, each providing low and high level care. Participants All 161 residents of the facilities were invited to participate. The only exclusion criterion was inability to obtain consent from the individual or designated guardian. 88 participants were recruited—66 females (75%), 22 males (25%) with average age 87.1 years (SD 5.5 years). Primary and secondary outcome measures Primary—presence of significant skin disease (defined as that which in the opinion of the investigators needed treatment or was identified as a patient concern) diagnosed clinically on full dermatological examination by a dermatologist or dermatology trainee. Secondary—functional and cognitive status (Rehabilitation Complexity Scale and Abbreviated Mental Test Score). Results 81.8% were found to have at least one significant condition. The most common disorders were onychomycosis 42 (47.7%), basal cell carcinoma 13 (14.8%), asteototic eczema 11 (12.5%) and squamous cell carcinoma in situ 9 (10.2%). Other findings were invasive squamous cell carcinoma 7 (8%), bullous pemphigoid 2 (2.3%), melanoma 2 (2.3%), lichen sclerosus 2 (2.3%) and carcinoma of the breast 1 (1.1%). Inflammatory disease was more common in those with little physical disability compared with those with serious physical disability (OR 3.69; 95% CI 1.1 to 12.6, p=0.04). No significant association was found between skin disease and cognitive impairment. Conclusions A high rate of dermatological disease was found. Findings ranged from frequent but not life-threatening conditions (eg, onychomycosis), to those associated with a significant morbidity (eg, eczema, lichen sclerosus and bullous pemphigoid), to potentially life-threatening (eg, squamous cell carcinoma, melanoma and breast cancer

    This study used electrophysiological measures of pre-stimulus effects that can occur prior to an unknown future event as an indicator of nonlocal intuition. Intuition in this context is considered as a process by which information normally outside the range of conscious awareness is detected at the cellular level by the heart, the brain, and the autonomic nervous system. This study extends the findings of previous experiments demonstrating that aspects of our physiology can respond to an emotionally engaging stimulus before it is actually experienced. The study evaluated a revised version of a roulette protocol, which included two pre-stimulus segments and included an analysis of the individual participant's data over eight separate trials in addition to a group-level analysis. We also assessed the potential effects of the moon phase on the pre-stimulus response outcomes and participant winning and amount won ratios. Data were collected under controlled laboratory conditions from 13 participants in 8 separate sessions using a modified version of a gambling paradigm protocol based on roulette. Half of the experimental sessions were conducted during the full moon phase and half during the new moon phase. Within each trial a total of three segments of physiological data were assessed. There were two separate pre-stimulus periods, pre-bet (4 sec) and postbet (12 sec), and a post-result period (6 sec). Participants were told that they were participating in a gambling experiment and were given an initial starting kitty and told they could keep any winnings over the course of 26 trials for each of the eight sessions. The physiological measures included the electrocardiogram (ECG), from which cardiac inter-beat-intervals (heart rate variability, HRV) were derived, and skin conductance. Before the participants participated in the first session, they completed the Cognitive Styles Index questionnaire, which assesses analytical vs intuitive styles. Overall, the results

    Psychoeducation is a key element in the management of patients with bipolar disorders. The present study explored the perception of patients and family members with respect to group psychoeducation for relatives. Patients (n = 20) and relatives (n = 26) were assessed with questionnaires about perceived benefits and quality of life (median 4 years after participation). A large majority (>80%) of relatives acknowledged benefits with respect to easier detection of the early warning signs of relapse, improved quality of life, feeling more involved, and engaging in higher quality caregiving activities. Patients were less positive in general, but agreed that the program had helped them deal with crises, increased their feeling of being understood by relatives, and promoted positive changes in the family (>60%). Perceived positive changes in the family were associated with higher quality of life for relatives and patients. The present study highlights the importance of communication enhancement in group psychoeducation for relatives. PMID:26313039

    We examined social participation in organized clubs and groups from childhood to adolescence in a sample of young people from Dunedin, New Zealand. Groups were broadly categorized as "sports" and "cultural/youth" groups. While the results indicated high levels of participation in childhood with a decline over the ensuing adolescent years, path analyses suggested strong continuities in participation over time. Both family "active-recreational" orientation (ARO) and "intellectual-cultural" orientation (ICO) predicted participation, and mediated the effects of disadvantage on participation. Participation was significantly related to adolescent attachment to parents, friends and school/workplace, as well as self-perceived strengths, after controlling for early family disadvantage and social support, peer attachment and literacy. The effect of participation in adolescence is to widen the "social convoy" to which young people are exposed as well as strengthening relationships within that convoy.

    The aim of this study was to evaluate the Yo-Yo Intermittent Recovery Test Level 1 (Yo-Yo IR1) ability to discriminate between elite, subelite junior basketball players, and a group of nonathletic healthy male athletes at 3 different age groups (U-14 to U-17). In a cross-sectional design, 119 age-matched participants spread over 3 groups, elite (n = 46), subelite (n = 42) junior basketball players, and nonathletic healthy male athletes (n = 31), were evaluated over a 5-week period. The participants undertook 2 familiarization trials of the Yo-Yo test performance and 3 test sessions on an indoor basketball court. When controlling for the effect of the participants' body mass, the results showed that elite athletes had a significantly higher Yo-Yo performance compared with the subelite athletes (1,271 ± 385 vs. 861 ± 428 m; p < 0.0017; effect size [ES] 1.0 ± 0.35) and the nonathletic group (1,271 ± 385 vs. 738 ± 345 m; p < 0.0017; ES 1.45 ± 0.38). No statistical differences (p > 0.0017; ES from 0.02 to 0.39) were noted between participants' performance levels across age groups. Typical between-performance levels and -age groups differences in the Yo-Yo IR1 were observed. However, when controlling for the effect of the participants' body mass, this study demonstrates that the Yo-Yo test is accurate only to discriminate elite junior basketball players but cannot be used to differentiate the basketball-specific aerobic performance for age.

    Objective To compare the prevalence of amblyopia, strabismus, and significant refractive error among African-American, American Indian, Asian, Hispanic, and non-Hispanic white preschoolers in the Vision In Preschoolers study. Design Multicenter, cross-sectional study. Participants Three- to 5-year old preschoolers (n = 4040) in Head Start from 5 geographically disparate areas of the United States. Methods All children who failed the mandatory Head Start screening and a sample of those who passed were enrolled. Study-certified pediatric optometrists and ophthalmologists performed comprehensive eye examinations including monocular distance visual acuity (VA), cover testing, and cycloplegic retinoscopy. Examination results were used to classify vision disorders, including amblyopia, strabismus, significant refractive errors, and unexplained reduced VA. Sampling weights were used to calculate prevalence rates, confidence intervals, and statistical tests for differences. Main Outcome Measures Prevalence rates in each racial/ethnic group. Results Overall, 86.5% of children invited to participate were examined, including 2072 African-American, 343 American Indian (323 from Oklahoma), 145 Asian, 796 Hispanic, and 481 non-Hispanic white children. The prevalence of any vision disorder was 21.4% and was similar across groups (P = 0.40), ranging from 17.9% (American Indian) to 23.3% (Hispanic). Prevalence of amblyopia was similar among all groups (P = 0.07), ranging from 3.0% (Asian) to 5.4% (non-Hispanic white). Prevalence of strabismus also was similar (P = 0.12), ranging from 1.0% (Asian) to 4.6% (non-Hispanic white). Prevalence of hyperopia >3.25 diopter (D) varied (P = 0.007), with the lowest rate in Asians (5.5%) and highest in non-Hispanic whites (11.9%). Prevalence of anisometropia varied (P = 0.009), with the lowest rate in Asians (2.7%) and highest in Hispanics (7.1%).

    Exaggerated cardiovascular reactivity to mental stressors may be a risk factor for cardiovascular disease. To determine if participation in a moderate intensity aerobic exercise training program reduces cardiovascular reactivity to laboratory stressors, 40 sedentary middle-aged males were randomly assigned: training group (n = 25) and control group (n = 15). Cardiovascular reactivity during and after three mental stressors (passive responding, push-button Stroop and verbal Stroop) and mild exercise (bicycle ergometer) was assessed before and after an 8-week intervention. VO2(peak) was determined using the Balke protocol. Among 19 subjects who completed the training, VO2(peak) increased 13.7%. Also, trained compared to untrained subjects showed significant reductions in baseline and absolute heart rate responses to all stressors. Baseline adjusted heart rates were significantly lower during push-button Stroop recovery and during verbal Stroop. Blood pressure, T-wave amplitude, finger pulse amplitude and pulse transit time responses were unaffected by exercise training. It was concluded that participation in a short-term, moderate intensity aerobic exercise training program may have a cardioprotective effect by significantly reducing absolute and baseline-adjusted heart rate responses to stressors.

    Indonesia's family planning program has been one of the most effective in the developing world in promoting contraceptive use and contributing to fertility transition. In evaluating why the program has worked, analysts have given much credit to a network of village family planning groups that developed from the 1970s to the 1990s and that blanketed the archipelago. These groups, composed primarily of female volunteers, made contraception available to women in even the most remote parts of the country, and acted as agents of family planning motivation. They have been labeled by the Indonesian state family planning agency as an example of effective community participation on a national scale. In this paper, I investigate this claim and find it to be simplistic. I provide extensive evidence that the creation of this network was orchestrated by the Indonesian state. On the other hand, I show that these groups are not fully state entities, as they have several characteristics that mark them as socially embedded institutions. They are best labeled as unusual state-society hybrids. In my investigation I draw on one of the newest paradigms in the discipline of political science--the state-society approach--to uncover the odd nature of this family planning network. More deeply, I argue that the state-society approach ought to be adopted in family planning analysis on a comprehensive basis. The traditional organizational and social-demographic approaches that have dominated the field offer only limited understanding of the nature of family planning programs in developing countries. The state-society approach is ideally suited to identifying how family planning programs are institutions of a political nature, embedded in states and societies, and transformed by and transformative of each.

    Background Little is known about the community structure of mental health Internet support groups, quantitatively. A greater understanding of the factors, which lead to user interaction, is needed to explain the design information of these services and future research concerning their utility. Objective A study was conducted to determine the characteristics of users associated with the subgroup community structure of an Internet support group for mental health issues. Methods A social network analysis of the Internet support group BlueBoard (blueboard.anu.edu.au) was performed to determine the modularity of the community using the Louvain method. Demographic characteristics age, gender, residential location, type of user (consumer, carer, or other), registration date, and posting frequency in subforums (depression, generalized anxiety, social anxiety, panic disorder, bipolar disorder, obsessive compulsive disorder, borderline personality disorder, eating disorders, carers, general (eg, “chit chat”), and suggestions box) of the BlueBoard users were assessed as potential predictors of the resulting subgroup structure. Results The analysis of modularity identified five main subgroups in the BlueBoard community. Registration date was found to be the largest contributor to the modularity outcome as observed by multinomial logistic regression. The addition of this variable to the final model containing all other factors improved its classification accuracy by 46.3%, that is, from 37.9% to 84.2%. Further investigation of this variable revealed that the most active and central users registered significantly earlier than the median registration time in each group. Conclusions The five subgroups resembled five generations of BlueBoard in distinct eras that transcended discussion about different mental health issues. This finding may be due to the activity of highly engaged and central users who communicate with many other users. Future research should seek to determine

    Recruitment of African Americans as research participants continues as a major challenge for researchers studying health and human behavior. Numerous reasons for low participation by African Americans have been cited, most of which evolve around four primary factors: social injustice, education, economics, and cultural differences. To ensure adequate representation of the diversity within the U.S. population in research, the federal government mandates the inclusion of individuals from underrepresented groups as study participants. For African Americans, this number is approximately 12%. Controversy exists, however, as to whether published research studies reflect adequate representation of African Americans as study participants. This article reports a successful approach to the recruitment and retention of 80 African American adults who participated in a study investigating language comprehension in aging. PMID:12491954

    Little is known regarding how individuals' hedonic ratings of a variety of foods interrelate and how hedonic ratings correspond to habitual dietary intake. Participant ratings of food appeal of 104 food images were collected while participants were in a fed state (n = 129). Self-reported frequency of intake of the food items, perceived hunger, body mass index (BMI), and dietary restraint were also assessed. Principal components analysis (PCA) was employed to analyze hedonic ratings of the foods, to identify component structures and to reduce the number of variables. The resulting component structures comprised 63 images loading on seven components including Energy-Dense Main Courses, Light Main Courses and Seafood as well as components more analogous to traditional food groups (e.g., Fruits, Grains, Desserts, Meats). However, vegetables were not represented in a unique, independent component. All components were positively correlated with reported intake of the food items (r's = .26-.52, p <.05), except for the Light Main Course component (r = .10). BMI showed a small positive relation with aggregated food appeal ratings (r = .19; p <.05), which was largely driven by the relations between BMI and appeal ratings for Energy-Dense Main Courses (r = .24; p <.01) and Desserts (r = .27; p <.01). Dietary restraint showed a small significant negative relation to Energy-Dense Main Courses (r = -.21; p <.05), and Meats (r = -.18; p <.05). The present investigation provides novel evidence regarding how individuals' hedonic ratings of foods aggregate into food components and how these component ratings relate to dietary intake. The notable absence of a vegetable component suggests that individuals' liking for vegetables is highly variable and, from an empirical standpoint, not related to how they respond hedonically to other food categories.

    Inter-group conflicts are common among many group-living animals and involve potentially complex motivations and interactions. Mammals living in multilevel societies offer a good opportunity to study inter-group conflicts. This study is the first to explore the function of sex-specific participation during inter-group conflicts within a multilevel society at the individual level. The Sichuan snub-nosed monkey (Rhinopithecus roxellana) is an endangered seasonal breeding species living in a multilevel society. From Sep 2007 to May 2008 we recorded 290 inter-group conflicts of a free-ranging provisioned band of R. roxellana in the Qinling Mountains of China to investigate the function of individual aggression during inter-group encounters. Our findings show that adult males were the main participants in inter-group conflicts, while females took part in them only occasionally. The male participation rate during the mating season, when adult females were estrous, was significantly higher than that during the non-mating season. Furthermore, males directed their aggression to other males, and directed more intense aggression towards bachelor males than towards other resident males. For both sexes, the participation rate as initiators was higher in the winter than that in the spring; and there was a significant positive correlation between group size and the participation rate as initiators. Our results suggest that inter-group aggression in Sichuan snub-nosed monkeys is linked to both mate defense and resource defense.

    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.

    Patellar instability has been extensively studied in selected, high-risk cohorts, but the epidemiology in the general population remains unclear. A longitudinal, prospective epidemiological database was used to determine the incidence and demographic risk factors for patellar dislocations presenting to emergency departments of the United States. The National Electronic Injury Surveillance System was queried for all patellar dislocations presenting to emergency departments between 2003 and 2008. Incidence rate ratios (IRRs) were then calculated with respect to sex, age, and race. The hypothesis was that patellar dislocation is influenced by sex, age, race, and athletic participation. An estimated 40,544 patellar dislocations occurred among an at-risk population of 1,774,210,081 person-years for an incidence rate of 2.29 per 100,000 person-years in the United States. When compared with males, females showed no significant overall or age-stratified differences in the rates of patellar dislocation (IRR 0.85, 95% CI 0.71, 1.00; p = 0.08; p > 0.05). Peak incidence of patellar dislocation occurred between 15 and 19 years of age (11.19/100,000 person-years). When compared with Hispanic race, black and white race were associated with significantly higher rates of patellar dislocation (IRR 4.30 [95% CI 1.63, 6.97; p = 0.02], IRR 4.02 [95% CI 1.06, 6.98; p = 0.03], respectively). Nearly half (51.9%) of all patellar dislocation occurred during athletic activity, with basketball (18.2%), soccer (6.9%), and football (6.3%) associated with the highest percentage of patellar dislocation during athletics. Age between 15 and 19 years is associated with higher rates of patellar dislocation. Sex is not a significant risk factor for patellar dislocation. Black and white race are a significant risk factor for patellar dislocation when compared with Hispanic race. Half of all patellar dislocation occurs during athletic activity. This study was conducted on the Level of evidence II.

    Purpose: 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. Design and Methods: 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). Results: 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. Implications: 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. PMID:25213483

  12. Perceptions of mental workload in Dutch university employees of different ages: a focus group study

    PubMed Central

    2013-01-01

    Background As academic workload seems to be increasing, many studies examined factors that contribute to the mental workload of academics. Age-related differences in work motives and intellectual ability may lead to differences in experienced workload and in the way employees experience work features. This study aims to obtain a better understanding of age differences in sources of mental workload. 33 academics from one faculty discussed causes of workload during focus group interviews, stratified by age. Findings Among our participants, the influence of ageing seems most evident in employees’ actions and reactions, while the causes of workload mentioned seemed largely similar. These individual reactions to workload may also be driven by differences in tenure. Most positively assessed work characteristics were: interaction with colleagues and students and autonomy. Aspects most often indicated as increasing the workload, were organisational aspects as obstacles for ‘getting the best out of people’ and the feeling that overtime seems unavoidable. Many employees indicated to feel stretched between the ‘greediness’ of the organisation and their own high working standards, and many fear to be assigned even less time for research if they do not meet the rigorous output criteria. Moreover, despite great efforts on their part, promotion opportunities seem limited. A more pronounced role for the supervisor seems appreciated by employees of all ages, although the specific interpretation varied between individuals and career stages. Conclusions To preserve good working conditions and quality of work, it seems important to scrutinize the output requirements and tenure-based needs for employee supervision. PMID:23506458

    Healthy aging simultaneously affects brain structure, brain function, and cognition. These effects are often investigated in isolation ignoring any relationships between them. It is plausible that age related declines in cognitive performance are the result of age-related structural and functional changes. This straightforward idea is tested in within a conceptual research model of cognitive aging. The current study tested whether age-related declines in task-performance were explained by age-related differences in brain structure and brain function using a task-switching paradigm in 175 participants. Sixty-three young and 112 old participants underwent MRI scanning of brain structure and brain activation. The experimental task was an executive context dual task with switch costs in response time as the behavioral measure. A serial mediation model was applied voxel-wise throughout the brain testing all pathways between age group, gray matter volume, brain activation and increased switch costs, worsening performance. There were widespread age group differences in gray matter volume and brain activation. Switch costs also significantly differed by age group. There were brain regions demonstrating significant indirect effects of age group on switch costs via the pathway through gray matter volume and brain activation. These were in the bilateral precuneus, bilateral parietal cortex, the left precentral gyrus, cerebellum, fusiform, and occipital cortices. There were also significant indirect effects via the brain activation pathway after controlling for gray matter volume. These effects were in the cerebellum, occipital cortex, left precentral gyrus, bilateral supramarginal, bilateral parietal, precuneus, middle cingulate extending to medial superior frontal gyri and the left middle frontal gyri. There were no significant effects through the gray matter volume alone pathway. These results demonstrate that a large proportion of the age group effect on switch costs can

    2014-10-01

    In studies on the development of cognitive processes, children are often grouped based on their ages before analyzing the data. After the analysis, the differences between age groups are interpreted as developmental differences. We argue that this approach is problematic because the variance in cognitive performance within an age group is considered to be measurement error. However, if a part of this variance is systematic, it can provide very useful information about the cognitive processes used by some children of a certain age but not others. In the current study, we presented 210 children aged 5 to 12 years with serial order short-term memory tasks. First we analyze our data according to the approach using age groups, and then we apply latent class analysis to form latent classes of children based on their performance instead of their ages. We display the results of the age groups and the latent classes in terms of serial position curves, and we discuss the differences in results. Our findings show that there are considerable differences in performance between the age groups and the latent classes. We interpret our findings as indicating that the latent class analysis yielded a much more meaningful way of grouping children in terms of cognitive processes than the a priori grouping of children based on their ages.

    Growing clinical and experimental evidence suggests that sterile inflammation contributes to alcoholic liver disease (ALD). High mobility group box-1 (HMGB1) is highly induced during liver injury; however, a link between this alarmin and ALD has not been established. Thus, the aim of this work was to determine whether HMGB1 contributes to the pathogenesis of ALD. Liver biopsies from patients with ALD showed a robust increase in HMGB1 expression and translocation, which correlated with disease stage, compared with healthy explants. Similar findings were observed in chronic ethanol-fed wild-type (WT) mice. Using primary cell culture, we validated the ability of hepatocytes from ethanol-fed mice to secrete a large amount of HMGB1. Secretion was time- and dose-dependent and responsive to prooxidants and antioxidants. Selective ablation of Hmgb1 in hepatocytes protected mice from alcohol-induced liver injury due to increased carnitine palmitoyltransferase-1, phosphorylated 5'AMP-activated protein kinase-α, and phosphorylated peroxisome proliferator-activated receptor-α expression along with elevated LDL plus VLDL export. Native and post-translationally modified HMGB1 were detected in humans and mice with ALD. In liver and serum from control mice and in serum from healthy volunteers, the lysine residues within the peptides containing nuclear localization signals (NLSs) 1 and 2 were non-acetylated, and all cysteine residues were reduced. However, in livers from ethanol-fed mice, in addition to all thiol/non-acetylated isoforms of HMGB1, we observed acetylated NLS1 and NLS2, a unique phosphorylation site in serine 35, and an increase in oxidation of HMGB1 to the disulfide isoform. In serum from ethanol-fed mice and from patients with ALD, there was disulfide-bonded hyperacetylated HMGB1, disulfide-bonded non-acetylated HMGB1, and HMGB1 phosphorylated in serine 35. Hepatocytes appeared to be a major source of these HMGB1 isoforms. Thus, hepatocyte HMGB1 participates in

    Scurlock, Debra

    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. PMID:25338266

  5. Spatial-Sequential Working Memory in Younger and Older Adults: Age Predicts Backward Recall Performance within Both Age Groups

    2016-01-01

    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. Linear regression analyses were then carried out within each age group, to assess the predictors of performance in each recall format (forward and backward). 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. The study suggests that backward spatial span is indeed more processing-intensive than forward span, even when both tasks include a retention period, and that age predicts

    Traditional burn mortality models are derived using all age groups. We hypothesized that age variably impacts mortality after burn and that age-specific models for children, adults, and seniors will more accurately predict mortality than an all-ages model. We audited data from the American Burn Association (ABA) National Burn Repository (NBR) from 2000 to 2009 and used mixed effect logistic regression models to assess the influence of age, total body surface area (TBSA) burn, and inhalation injury on mortality. Mortality models were constructed for all ages and age-specific models: children (<18 years), adults (18-60 years), and seniors (>60 years). Model performance was assessed by area under the receiver operating curve (AUC). Main effect and two-way interactions were used to construct age-group specific mortality models. Each age-specific model was compared to the All Ages model. Of 286,293 records 100,051 had complete data. Overall mortality was 4% but varied by age (17% seniors, <1% children). Age, TBSA, and inhalation injury were significant mortality predictors for all models (p<0.05). Differences in predicted mortality between the All Ages model and the age-specific models occurred in children and seniors. In the age-specific pediatric model, predicted mortality decreased with age; inhalation injury had greater effect on mortality than in the All Ages model. In the senior model mortality increased with age. Seniors had greater increase in mortality per 1% increment in burn size and 1 year increase in age than other ages. The predicted mortality in seniors using the senior-specific model was higher than in the All Ages model. "One size fits all" models for predicting burn outcomes do not accurately reflect the outcomes for seniors and children. Age-specific models for children and seniors may be advisable. PMID:24846014

    We examined the relationship between treatment quality, using during-treatment process measures, and mutual help group (e.g., Alcoholics Anonymous) attendance after outpatient substance use disorder (SUD) treatment for 739 clients in the Alcohol and Drug Services Study. Logistic regression models estimated any and regular mutual help attendance after treatment. Clients referred to mutual help groups were significantly more likely to attend any mutual help after treatment. Results were mixed for facility offered mutual help groups; treatment engagement and retention were not significant. These findings offer treatment providers further evidence of the importance of referring clients to post-treatment mutual help groups, an effective, low-cost option.

    Low childhood socioeconomic status (SES) has been linked with insulin resistance (HOMA-IR) in adulthood. Our aim was to examine if maternal and paternal education, as indicators of childhood SES, equally contributed to increased HOMA-IR in later life. Of 5,115 adults from the Coronary Artery Disease Risk Development in Young Adults (CARDIA) Study aged 18-30 years in 1985-1986, data on 1,370 females and 1,060 males with baseline and 20 year follow-up data were used to estimate associations of maternal and paternal education with HOMA-IR, adjusting for personal education, BMI, lipids, blood pressure, and lifestyle factors. Parental education was determined as high with ≥ 12 years of schooling and classified as both high, only mother high, only father high, both low education. Distinct combinations of maternal and paternal education were associated with HOMA-IR across race and sex groups. Lowest year 20 HOMA-IR in European American (EA) females occurred when both parents were better educated, but was highest when only the father had better education. HOMA-IR was lowest in African American (AA) participants when the mother was better educated but the father had less education, but was highest when both parents were better educated. Parental education was unrelated to HOMA-IR in EA males. Associations of parental education with HOMA-IR are seen in AA females, AA males, and EA females but not in EA males. The distinct combinations of parental education and their associations with HOMA-IR especially in AA participants need to be addressed in further research on health disparities.

    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.

  19. Benefits of gregarious feeding by aposematic caterpillars depend on group age structure.

    PubMed

    2015-03-01

    Gregarious feeding is a common feature of herbivorous insects and can range from beneficial (e.g. dilution of predation risk) to costly (e.g. competition). Group age structure should influence these costs and benefits, particularly when old and young larvae differ in their feeding mode or apparency to predators. We investigated the relative value of gregarious feeding by aposematic larvae of Uresiphita reversalis that we observed feeding in groups of mixed ages and variable densities on wild Lupinus diffusus. In a manipulative field experiment, the survivorship and growth of young larvae were enhanced in the presence of older conspecifics, but not in large groups of similarly aged larvae. Estimates of insect damage and induced plant responses suggest that mixed-age groups enhance plant quality for young larvae while avoiding competition. We conclude that benefits of gregariousness in this species are contingent on group age structure, a finding of significance for the ecology and evolution of gregariousness and other social behaviours.

    2016-01-01

    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

    2013-10-01

    Minorities are underenrolled in clinical research trials, and one-third of trials are underenrolled overall. The role of payment has not been studied at the national level as an explanation for enrollment patterns. Our objective was to examine the distribution of self-reported previous research participation across different sociodemographic groups; to assess the public's perception of fair payment for a low-risk medicine trial and the association between requested payment and sociodemographic characteristics; to estimate the amount of payment for a medication trial to achieve proportional representation of minorities and different socioeconomic groups. This was a cross-sectional study with nationally representative data collected in 2011 by the C.S. Mott Children's Hospital National Poll on Children's Health. To determine the relationship between perceived fair payment and individual-level characteristics, we used multivariable linear regression. With 60% participation rate, in a sample of 2,150 respondents 11% (n = 221) of the sample had previously participated in medical research. Requested payment differed significantly by racial/ethnic group with Hispanics requesting more payment than non-Hispanic whites (0.37 [95%CI 0.02, 0.72]) In contrast to payment at $49, $149, and $249, payment at $349 yielded proportional representation of racial/ethnic minority groups. Hispanics requested higher payment for research participation, suggesting a possible explanation for their underenrollment.

    Inverted extensional basins with continental deposits of the Mitu Group straddle the Eastern Cordillera of Peru. The present study investigates the Mitu Group of south-east Peru (13-16°S), which consists of continental clastic sedimentary rocks and interbedded basaltic to andesitic lavas. There is a paucity of geochemical and geochronological data from the Mitu Group, and the interpretation of its evolution is complicated by i) rapid changes in fault structure along-strike of the graben system, and ii) inversion during Andean orogenesis. Due to dominating coarse-grained clastics, the Mitu Group is devoid of fossils and its age is poorly bracketed to the Permo-Triassic, based on its stratigraphic relationships with the underlying Copacabana and overlying Pucará groups. The upper strata of the Copacabana Group have been constrained by palynology to the Artinskian, while marine fossils at the base of the Pucará Group indicate a Norian age. The Pucará Group is only present in northern Peru, whereas the Mitu Group has an erosional contact with overlying Cretaceous sandstones in the study area. Preliminary data suggest that the lower Mitu Group is middle Triassic, leaving a significant hiatus between the Copacabana and Mitu groups. Laser ablation ICP-MS U-Pb zircon dating was utilized to characterize pre- and syn-rift detrital zircon assemblages in sandstones, as well as to date the syn-rift volcanic and plutonic activity. Detrital zircon U-Pb age histograms of medium grained sandstones in the pre-rift Ambo and Copacabana groups contain several age populations, which can be immediately linked to major events identified along the western Gondwanan margin, such as the Sunsas/Grenville (1 Ga) and Pampean (0.55 Ga) orogenies, as well as the Famatinian arc (0.45 Ga). The youngest zircon in the population assigns a maximum deposition age to the rock; these zircons are of late Mississippian age for the Ambo and latest Pennsylvanian for the Copacabana groups. The

    Many older adults face challenges that prevent them from accomplishing common daily activities such as moving around, home maintenance, and leisure activities. There is still a need to examine and understand how environmental factors impact daily participation across gender. This study sought to make a qualitative comparison of gender differences regarding environmental barriers to participation in daily occupations from the perspectives of older adults who live alone in Puerto Rico. Twenty-six Hispanic older adults, 70 years or older participated in this study. We used a descriptive qualitative research design in which researchers administered an in-depth interview to each participant. The results elucidated that women were more likely than men to experience restricted participation due to lack of accessibility of the built environment and transportation systems. The findings could help with the development of tailored, occupation-based, preventive interventions that address gender specific environmental barriers and promote greater participation among both women and men. Further research is required to explore whether these environmental barriers to occupational participation remain consistent across living situations, socioeconomic status and ethnicity.

    The effect of 12-step mutual help groups (e.g., Narcotics Anonymous) on members' friendship networks has received little attention. This 1-year longitudinal study examined such effects in a sample of 2,337 male substance abuse inpatients, 57.7% of whom became significantly involved in 12-step activities (e.g., reading program literature, attending meetings) after treatment. An a priori model of the interplay of 12-step involvement) and friendship networks was tested using structural equation modeling, and found to have excellent fit to the data. Twelve-step group involvement after treatment predicted better general friendship characteristics (e.g., number of close friends) and substance abuse-specific friendship characteristics (e.g., proportion of friends who abstain from drugs and alcohol) at follow-up. Results are discussed in terms of how mutual help group involvement benefits patients and how the self-help group evaluation paradigm should be broadened. PMID:9231993

    Little is known about life course differences in social role participation among those with chronic diseases. This study examined role salience (i.e., importance), role limitations, and role satisfaction among middle- and older-aged adults with and without osteoarthritis (OA) and its relationship to depression, stress, role conflict, health care utilization and coping behaviours. Participants were middle- and older-aged adults with OA (n = 177) or no chronic disabling conditions (n = 193), aged ≥40 years. Respondents were recruited through community advertising and clinics in Ontario, Canada (2009-2010). They completed a 45-50 min telephone interview and 20 min self-administered questionnaire assessing demographics (e.g., age, gender); health (e.g., pain, functional limitations, health care utilization); the Social Role Participation Questionnaire (SRPQ) (role salience, limitations, satisfaction in 12 domains), and psychological variables (e.g., depression, stress, role conflict, behavioural coping). Analyses included two-way ANOVAs, correlations, and linear regression. Results indicated that middle-aged adults (40-59 years) reported greater role salience than older-aged adults (60 + years). Middle-aged adults with OA reported significantly greater role limitations and more health care utilization than all other groups. Middle-aged adults and those with OA also reported greater depression, stress, role conflict, and behavioural coping efforts than older adults or healthy controls. Controlling for age and OA, those with higher role salience and greater role limitations reported more health care utilization. Those with greater role limitations and lower role satisfaction reported greater depression, stress, role conflict, and behavioural coping. This study has implications for research and interventions, highlighting the need to characterize role participation as multidimensional. It points to the importance of taking into account the meaning of roles at

    Now a days, benign prostatic hyperplasia and carcinoma of the prostate are the most common disorders in men. A cross sectional descriptive study was conducted in Department of Anatomy, Mymensingh Medical College, Mymensingh to find out the difference in weight of the prostate gland of Bangladeshi people in relation to age. The present study was performed on 67 postmortem human prostate gland collected from the morgue in the Department of Forensic Medicine, Mymensingh Medical College by non random purposive sampling technique. The specimens were collected from Bangladeshi cadaver of age ranging from 10 to 80 years. All the specimens were grouped into three categories - Group A (upto 18 years), Group B (19 to 45 years) and Group C (above 45 years) according to age. Dissection was performed according to standard autopsy techniques. The weight of the prostate gland were measured and recorded. The mean weight of the prostate gland was 10.13gm in Group A, 17.27gm in Group B and 22.50gm in Group C. Variance analysis shows that mean differences of weight of the prostate were highly significant among all age groups. The weight of prostate gland was found to increase with increased age. For statistical analysis, differences between age groups were analyzed by using students unpaired 't' test. The present study will help to increase the information pool on the weight of prostate gland of Bangladeshi people. PMID:27612887

    Active participation in immersive simulation experiences can result in technical and non-technical skill enhancement. However, when simulations are conducted in large groups, maintaining the interest of observers so that they do not disengage from the learning experience can be challenging. We implemented Tag Team Simulation with the aim of ensuring that both participants and observers had active and integral roles in the simulation. In this paper we outline the features of this innovative approach and provide an example of its application to a pain simulation. Evaluation was conducted using the Satisfaction with Simulation Experience Scale. A total of 444 year nursing students participated from a population of 536 (response rate 83%). Cronbach's alpha for the Scale was .94 indicating high internal consistency. The mean satisfaction score for participants was 4.63 compared to 4.56 for observers. An independent sample t test revealed no significant difference between these scores (t (300) = -1.414, p = 0.16). Tag team simulation is an effective approach for ensuring observers' and participants' active involvement during group-based simulations and one that is highly regarded by students. It has the potential for broad applicability across a range of leaning domains both within and beyond nursing. PMID:25936431

    Background and Purpose Physical activity has many benefits for older adults, but adherence is often low. The purposes of this study were to: 1) identify motivators and barriers for participation in EnhanceFitness (EF), a group-based exercise program; and 2) quantitatively examine the association between motivators, barriers and individual characteristics, and ongoing participation in the program. Methods This was a prospective, cross-sectional study. We mailed a pilot, investigator-developed survey to assess motivators and barriers to exercising to 340 adults who started a new EF class, regardless of their attendance rate. We pre-coded surveys based on class attendance, with former participants defined as having no attendance a month or more before a four-month fitness check. Results Of the 241 respondents (71% response rate), 61 (25%) were pre-coded as former participants and 180 (75%) as current participants. The mean age of respondents was 71 and they were predominately female (89%). More than half of respondents were Caucasian (58%), and almost half were married (46%). Former participants reported lower total motivation scores compared to current participants (p<0.01) and had a significantly higher mean total barrier score (p < 0.001). The effects of 5 barriers (“Class was too hard,” “Class was too easy,” “I don’t like to exercise,” “Personal illness,” “Exercise caused pain”) and 2 motivators (“I want to exercise,” and “I plan exercise as part of my day”) were significantly different between current and former participants. Discrete event history models show dropout was related positively to ethnicity (Caucasians were more likely to drop out), and health-related barriers. Discussion In newly formed EF classes, participants who drop out report more program, psychosocial, and health barriers, and fewer program and psycho-social motivators. Total barrier score and health barriers significantly predict a participant’s dropping out

    Background Adherence with inhaled controller medications for asthma is known to be highly variable with many patients taking fewer doses than recommended for consistent control of lung inflammation. Adherence also worsens as children become teenagers, although the exact causes are not well established. Objective To use focus group methodology to examine beliefs, feelings, and behaviors about inhaled asthma controller medication in adolescents and young adults who had previously participated in a longitudinal study of asthma treatment adherence and outcome in order to develop more effective management strategies. Methods Twenty-six subjects participated in 6 focus groups comprised of 3-5 young adults (age range 12-20 years). Verbatim transcripts of these groups were analyzed using the long-table method of content analysis to identify key themes raised by participants. Results A variety of beliefs, feelings and behaviors influence the adolescent’s decision about how to use their asthma medication. Some of the adolescents understood the importance of daily medication and were committed to the treatment plan prescribed by their provider. Poorer adherence was the product of misinformation, incorrect assumptions about their asthma, and current life situations. Conclusions These results, by highlighting potential mechanisms underlying both better and worse adherence inform the development of strategies to improve adherence behavior in adolescents and young adults with asthma. Knowledge of the specific beliefs, feelings and behaviors that underlie adolescents’ use of inhaled asthma controller medication will help providers maximize treatment adherence in this notoriously difficult patient population.

    This study explored effect of age on encoding, retention, and retrieval components of memory functioning in a sample of 156 healthy, elderly subjects between the ages of 57 and 85, partitioned into four age groups. Memory assessment was based on subjects' performance on the RAVLT, which consisted of five free-recall trials, recall after interference, and recognition trial. Significant group differences in recall were found on all five learning trials, whereas rates of learning, forgetting, and recognition did not differ for four age groups. In addition, primacy/recency effect was equally strong for all groups. Results suggest faulty retrieval mechanisms, whereas encoding and retention processes did not prove to be affected by aging.

    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 early 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.

    Clinical study of two groups of females beyond age of 65, institutionalized for delusional manifestations of schizophrenic nature and presenting also, at the time of examination, a pronounced paranoid state. In the first group: the manifestations had arisen before the age of 45. In the second group, after the age of 65. This study has demonstrated certain psychopathological characteristics suggesting the presence of personality problems definitely more profound in patients of the first group: autistic state, asthenia, thought disorder, incoherence and vagueness of delusional subjects, ordinarily much more unreal are characteristics of the first group in comparison to the second. This seems to bring evidence that these two paranoid states (paranoid schizophrenia in adult age and paranoid state in senility) are, at first sight, pathological entities based on personality problems of very different intensity.

    Do children derive different benefits from group collaboration at different ages? In the present study, 183 children from two age groups (8.8 and 13.4 years) took part in a class quiz as members of a group, or individually. In some groups, cohesiveness was made salient by awarding prizes to the top performing groups. In other groups, prizes were awarded to the best performing individuals. Findings, both in terms of social outcomes and performance in the quiz, indicated that the 8-year olds viewed the benefits of group membership in terms of the opportunities to receive information from other members. The 13-year olds, in contrast, viewed group collaboration as a constructive process where success was connected with group cohesiveness.

    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

    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.

    Aim: The present study was carried out to analyze the disposal rate in different age groups of Karan Fries (KF) males in National Dairy Research Institute herd. Materials and Methods: Records on 1740 KF crossbred bulls born during the period 1997-2012 were collected with an objective to ascertain the effect of genetic and non-genetic (Period of birth and season of birth) factors on the disposal pattern of KF males. The percent of animals disposed from the herd due to mortality and culling was calculated by proportion using descriptive statistics. The data were subjected to Chi-square test to test the difference due to different factors. Results: Overall disposal rate for the different age groups of 0-1 m, 1-2 m, 2-3 m, 3-6 m, 6-18 m, 18 m-3 year and 3-5 year were calculated as 17.9, 16.3, 14.2, 25.8, 49.0, 37.6 and 51.65%, respectively. In the age groups, 3-6 m, 6-18 m and 3-5 year, effect of periods of birth were found to be statistically significant (p<0.01) for overall disposal rate. Across different seasons of birth, overall disposal rates differed significantly (p<0.01) in different age group except in 3-5 year age group. Differences in overall disposal rate due to genetic group were statistically significant (p<0.01) in 1-2 m, 2-3 m, 3-6 m, 6-18 m, 18-3 year and 3-5 year age groups. Conclusion: Overview of the results indicated that higher overall disposal rate in age group of 1 month was due to mortality while, in the age groups of >1 month, culling was the primary cause.

    2007-01-01

    Participation in 12-step groups (12SG) during and after formal treatment has been associated with positive outcome among substance users. However, the effectiveness of 12SG may be limited by high attrition rates and by low participation, areas on which there has been little research. Clinicians play an important role in fostering 12-step participation, and the insights which they develop in their practice can greatly contribute to informing the research process. Yet, little is known about clinicians’ attitudes about 12-step groups or about their experiences in referring clients. This study surveyed clients (N = 101) and clinicians (N = 102) in outpatient treatment programs to examine 12-step related attitudes and to identify potential obstacles to participation. Data collection was conducted between May 2001 and January 2002 in New York City. Both client and clinician samples were primarily African-American and Hispanic; 32% of clients reported substance use in the previous month, with crack and marijuana cited most frequently as primary drug problem. On average, clinicians had worked in the treatment field for 8 years. Both staff and clients viewed 12SG as a helpful recovery resource. Major obstacles to participation centered on motivation and readiness for change and on perceived need for help, rather than on aspects of the 12-step program often cited as points of resistance (e.g., religious aspect and emphasis on powerlessness). Clinicians also frequently cited convenience and scheduling issues as possible obstacles to attending 12SG. Clinical implications of these findings are discussed, including the importance of fostering motivation for change, the need to assess clients’ beliefs about and experiences with 12SG on a case by case basis, and to find goodness of fit between clients’ needs and inclinations on the one hand, and the tools and support available within 12-step groups on the other.

    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.

    Bacteroides vulgatus is a member of the human microbiota whose abundance is increased in patients with Crohn's disease. We show that a B. vulgatus glycoside hydrolase from the carbohydrate active enzyme family GH123, BvGH123, is an N-acetyl-β-galactosaminidase that acts with retention of stereochemistry, and, through a 3-D structure in complex with Gal-thiazoline, provide evidence in support of a neighbouring group participation mechanism.

  7. Influence of alkoxy groups on rates of acetal hydrolysis and tosylate solvolysis: electrostatic stabilization of developing oxocarbenium ion intermediates and neighboring-group participation to form oxonium ions.

    The hydrolysis of 4-alkoxy-substituted acetals was accelerated by about 20-fold compared to that of sterically comparable substrates that do not have an alkoxy group. Rate accelerations are largest when the two functional groups are linked by a flexible cyclic tether. When controlled for the inductive destabilization, an alkoxy group can accelerate acetal hydrolysis by up to 200-fold. The difference in rates of acetal hydrolysis between a substrate where the alkoxy group was tethered to the acetal group by a five-membered ring compared to one where it was tethered by an eight-membered ring was less than 100-fold, suggesting that fused-ring intermediates were not formed. By comparison, the difference in rates of solvolysis of structurally related tosylates were nearly 10(6)-fold between the five- and eight-membered ring series. This observation implicates neighboring-group participation in the solvolysis of tosylates but not in the hydrolysis of acetals. The acceleration of acetal hydrolysis by an alkoxy group is better explained by electrostatic stabilization of intermediates that accumulate positive charge at the acetal carbon atom.

    Using data from a nationally representative British birth cohort we characterized the type and diversity of leisure-time physical activity that 2,188 participants (age 60–64 years) engaged in throughout the year by gender and obesity. Participants most commonly reported walking (71%), swimming (33%), floor exercises (24%) and cycling (15%). Sixty-two percent of participants reported ≥2 activities in the past year and 40% reported diversity on a regular basis. Regular engagement in different types of activity (cardio-respiratory, balance/flexibility and strength) was reported by 67%, 19% and 11% of participants, respectively. We found gender differences, as well as differences by obesity status, in the activities reported, the levels of activity diversity and activity type. Non-obese participants had greater activity diversity, and more often reported activities beneficial for cardio-respiratory health and balance/flexibility than obese participants. These findings may be used to inform the development of trials of physical activity interventions targeting older adults, and those older adults with high body mass index. PMID:24911018

    Group IVA phospholipase A2 (IVA-PLA2) is an enzyme that intiates the arachidonic acid pathway and plays an important role in inflammation. We demonstrate that IVA-PLA2 deficiency suppresses lipid deposition in the liver, which was induced by administration of a high-fat and -cholesterol diet (HFCD) for 16 wk in mice. Herein, we performed 2-dimensional gel-based comparative proteomics to further define the suppressive effect of IVA-PLA2 deficiency on fatty liver formation. In comparisons among 4 groups, wild-type (WT)/normal diet (ND), IVA-PLA2-deficient knockout (KO)/ND, WT/HFCD, and KO/HFCD, 4 proteins, 3 of which are associated with hepatic fibrosis, were identified as molecules, of which altered expression by HFCD was suppressed in KO mice compared to WT mice. Therefore, we assessed the effect of IVA-PLA2 deficiency on hepatic fibrosis induced by HFCD or carbon tetrachloride (CCl4) in mouse models. Biochemical and histological analyses revealed that IVA-PLA2 deficiency markedly reduced overall collagen accumulation in the liver of HFCD- and CCl4-derived mouse models. We found that IVA-PLA2 deficiency prevented activation of hepatic stellate cells and infiltration of F4/80-positive macrophages without affecting other immunocytes such as CD8+ lymphocytes and natural killer cells. In summary, IVA-PLA2 deficiency attenuates not only lipid deposition in the liver but also hepatic fibrosis formation.

    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. PMID:26278132

    The objective of the present study was to explore associations between psychosocial workload and mental health complaints in different age groups. A questionnaire was sent to 2021 employees of a Dutch railway company. Six aspects of psychosocial workload (work pressure, mental workload, emotional workload, autonomy, social support from colleagues and social support from supervisors) and three mental health outcomes (work-related fatigue, stress and burnout) were assessed. Associations between the aspects of psychosocial workload (distributed into tertiles) and health complaints were analysed by logistic regression analysis in four age groups (22-35, 36-45, 46-55 and 56-66 years old). In all age groups, worse work pressure was a significant risk factor for having mental health complaints. Worse emotional load in the younger employees and lack of social support in older employees were associated with a higher risk of having mental health complaints. Age-specific preventive measures should be implemented on both individual and group levels. STATEMENT OF RELEVANCE: With an ageing workforce, understanding relationships between age and work-related health ailments is increasingly important. This study found that emotional workload in younger and lack of social support in older employees were associated with a higher risk of mental health complaints. Work pressure was a risk factor in all age groups.

Rising real income and the institution of broad based social security systems have encouraged older workers to leave the labor force at younger ages. p]Reductions in older age mortality have also affected the less developed regions. Increases in the number of older persons, coupled with continuing high fertility, have increased the size of the working age population through both large entry cohorts and longevity of current workers.

    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.

    We present a self-consistent, absolute isochronal age scale for young (<~ 200 Myr), nearby (<~ 100 pc) moving groups, which is consistent with recent lithium depletion boundary ages for both the β Pic and Tucana-Horologium moving groups. This age scale was derived using a set of semi-empirical pre-main-sequence model isochrones that incorporate an empirical colour-T eff relation and bolometric corrections based on the observed colours of Pleiades members, with theoretical corrections for the dependence on logg. Absolute ages for young, nearby groups are vital as these regions play a crucial role in our understanding of the early evolution of low- and intermediate-mass stars, as well as providing ideal targets for direct imaging and other measurements of dusty debris discs, substellar objects and, of course, extrasolar planets.

    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 Center for High Angular Resolution Astronomy Array. At least four of these stars have large rotational velocities (v{sin}i ≳ 170 {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 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 opposed to those that are several times larger than the limit. Under the assumption of coevality, the spread in ages can be used as a test of both the prescription presented here and the MESA evolutionary code for rapidly rotating stars. With our validated technique, we combine these age estimates and determine the age of the moving group to be 414 ± 23 Myr, which is consistent with, but much more precise than previous estimates.

    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.

  14. Justice between age groups: an objection to the prudential lifespan approach.

    PubMed

    Jecker, Nancy S

    2013-01-01

    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.

    Little attention has been paid to the physical activity (PA) and nutrition behaviors of middle-aged men; thus, the aim of this study was to gather information and gain insight into the PA and nutrition behaviors of these men. Six focus group sessions were undertaken with middle-aged men (N = 30) from regional Australia to explore the challenges and motivations to PA participation and healthy eating. Men had a good understanding of PA and nutrition; however, this was sometimes confounded by inconsistent media messages. Work commitments and family responsibilities were barriers to PA, while poor cooking skills and abilities were barriers to healthy eating. Disease prevention, weight management, and being a good role model were motivators for PA and healthy eating. By understanding what a man wants, PA and nutrition interventions can be designed and delivered to meet the needs of this hard-to-reach population.

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.

    We examined whether self-ratings of "being active" among older people living in four different settings (major city high and lower density suburbs, a regional city, and a rural area) were associated with out-of-home participation and outdoor physical activity. A mixed-methods approach (survey, travel diary, and GPS tracking over a one-week period) was used to gather data from 48 individuals aged over 55 years. Self-ratings of "being active" were found to be positively correlated with the number of days older people spent time away from home but unrelated to time traveled by active means (walking and biking). No significant differences in active travel were found between the four study locations, despite differences in their respective built environments. The findings suggest that additional strategies to the creation of "age-friendly" environments are needed if older people are to increase their levels of outdoor physical activity. "Active aging" promotion campaigns may need to explicitly identify the benefits of walking outdoors to ambulatory older people as a means of maintaining their overall health, functional ability, and participation within society in the long-term and also encourage the development of community-based programs in order to facilitate regular walking for this group.

    Objective To explore how older adults from three prominent ethnoracial groups experience cognitive decline and aging. Method Semistructured key informant interviews (KIIs) and focus groups (FGs) were conducted with caregivers, experts, and older adults. Results (N = 75). Fifteen KIIs regarding cognitive aging issues were conducted among health care professionals and community-based agencies serving older adults. Eight FGs included family caregivers and physicians, and six FGs with Latino, African American, and White older adult community members. Major themes included (a) personal expectations about aging, (b) societal value of older adults, (c) model of care preferred, and (d) community concerns. An overarching theme was a sense of loss associated with aging; however, how this loss was experienced and dealt with varied. Discussion Distinct patterns of concerns and views are important to understand for the development of programs aimed at meeting the needs of diverse older adult community members to improve health outcomes.

    The retina was studied in albino laboratory male rats of two age groups (12 and 24 months), 10 animals in each subjected to chronic combined stress. The stress was caused in animals by simultaneous exposure to pulsed light, loud sound, swinging and restriction of mobility for 7 days, 30 mm daily. The retina of intact rats of the corresponding age groups (n = 20) served as control. Enucleated eyes of stressed and control animals were processed with standard histological technique and stained with Nissl's method and hematoxylin-eosin. The retina of the stressed animals of both age groups showed the decrease in the number of cells and the disarrangement of its layers, most pronounced in the layers of photoreceptor neurons and ganglion cells. The comparative morphometric analysis demonstrated a reduction of the layer thickness and cell numerical density in the retina of stressed animals, both young (12 months) and old (24 months), as compared to that of control animals.

    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. PMID:27468992

    This Public Participation Plan outlines activities being planned to: (1) brief the public on results of the remedial investigation and feasibility study, (2) discuss the proposed plan for remediation of Operable Unit 7-13/14 with the public, and (3) encourage public participation in the decision-making process. Operable Unit 7-13/14 is the Comprehensive Remedial Investigation/Feasibility Study for Waste Area Group 7. Analysis focuses on the Subsurface Disposal Area (SDA) within the Radioactive Waste Management Complex at the Idaho National Laboratory (Site). This plan, a supplement to the Idaho National Laboratory Community Relations Plan (DOE-ID 2004), will be updated as necessary. The U.S. Department of Energy (DOE), Idaho Department of Environmental Quality (DEQ), and U.S. Environmental Protection Agency (EPA) will participate in the public involvement activities outlined in this plan. Collectively, DOE, DEQ, and EPA are referred to as the Agencies. Because history has shown that implementing the minimum required public involvement activities is not sufficient for high-visibility cleanup projects, this plan outlines additional opportunities the Agencies are providing to ensure that the public’s information needs are met and that the Agencies can use the public’s input for decisions regarding remediation activities.

    The purpose of this study was to determine the extent and integration of osteoporosis knowledge in three age groups of women and compare knowledge to calcium intake and weight-bearing physical activity (WBPA). In this cross-sectional study, knowledge, calcium intake and WBPA were assessed using probe interviews, a food frequency and an activity questionnaire, respectively. Seventy-five white women were separated into three groups: young (25-35 years), middle aged (36-46 years) and postmenopausal (50+ years). Concept maps were used to assess knowledge (concepts, integration and misconceptions). Calcium intakes from diet, supplements and fortified orange juice were estimated as were minutes of daily WBPA. Analysis of covariance was used to compare knowledge, calcium intake and WBPA by age group. Covariates included education, family history, physical problems making exercise difficult, and lactose intolerance. Chi square analysis was used to determine differences in these covariates across age groups. Correlations and regression analysis were used to determine relationships between knowledge and behaviors. Knowledge scores averaged 32-44 points (183 possible). Average calcium intake in all groups exceeded the Dietary Reference Intake's recommended Adequate Intake but 20-24% consumed less than 60% of the AI. Housework, walking at work, and standing at home and work accounted for 90% of WBPA. Knowledge about osteoporosis was limited and not associated with age, WBPA or calcium intake. Calcium intake and WBPA were not associated with age. Practitioners need to provide explicit information on osteoporosis and risk reducing behaviors to women of all ages. PMID:12238730

    The Sirius Group is a mixed sequence of interbedded diamictite and mudstone of Pliocene age found at scattered locations along the length of the Transantarctic Mountains. Sirius Group rocks are usually considered tillites, but contain some very "un-tillite" elements. Within section and from site to site, Sirius Group rocks vary considerably in terms of texture and relative abundance of clast lithologies, recording a history that includes shifting influences of glacial, lacustrine, fluvial and wetland processes. The colorful heritage of the Sirius Group has generated a lot of interest due to its potential as a record of changes in the behavior of the East Antarctic icesheet during a climatologically interesting period.

    We investigate the resolved stellar content of three predominantly old and metal-poor early-type dwarf galaxies in the Centaurus A group (at a distance of ˜4 Mpc). Our goal is to estimate the fraction of the intermediate-age populations (IAPs) and the period of most recent star formation from their luminous AGB stars. We combine optical HST/ACS and near-infrared VLT/ISAAC images to identify AGB star candidates. The first dataset provides high-resolution photometry while the second one permits us to disentangle the galaxies’ stellar content from the foreground contamination and to characterize the IAPs. The IAP fraction is found to be very low in the target galaxies (up to ˜15%). We compare the results to our own Local Group.

    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.

    With the primary objective of attracting and retaining students from underrepresented backgrounds in the sciences, evaluation of one institution's program has been ongoing over the past three years. Interviews with mentors in the program followed by focus groups conducted with mentees reveal key factors that shape undergraduate students' research experiences. In the present study, attention is given to data gathered from 15 mentees in the program, the majority of whom have enrolled in community colleges, represent low socioeconomic backgrounds, and are nontraditional students. The results from focus groups with the mentees provide information on the benefits of participating in the program, characteristics of good mentors, challenges to the mentoring relationship, and the effects of underrepresented status on pursuit of advanced degrees. Comparisons of mentees' comments about the mentoring relationship with mentors' comments reveal similar themes and patterns while also demonstrating interesting differences. The qualitative findings are also juxtaposed with participants' responses on the Survey of Undergraduate Research Experiences. Taken together, the data enhance our understanding of the experiences of underrepresented students in faculty-mentored research programs and highlight challenges and perspectives of students who are transferring to the university from a community college.

    The objective of the study was to examine the feasibility and benefits of a group resistance training exercise programme for improving muscle function in institutionalised older adults. A feasibility and acceptability study was designed for a residential aged care (RAC) facility, based on the Gold Coast, Australia. Thirty-seven adults, mean age 86.8 ± 6.1 years (30 females) living in a RAC facility. Participants were allocated into an exercise (n = 20) or control (n = 17) group. The exercise group, the Group Aged Care Exercise (GrACE) programme, performed 12 weeks of twice weekly resistance exercises. Feasibility was measured via recruitment rate, measurement (physiological and surveys) completion rate, loss-to-follow-up, exercise session adherence, adverse events, and ratings of burden and acceptability. Muscle function was assessed using gait speed, sit-to-stand and handgrip strength assessments. All intervention participants completed pre- and post-assessments, and the exercise intervention, with 85% (n = 17) of the group attending ≥ 18 of the 24 sessions and 15% (n = 3) attending all sessions. Acceptability was 100% with exercise participants, and staff who had been involved with the programme strongly agreed that the participants “Benefited from the programme.” There were no adverse events reported by any participants during the exercise sessions. When compared to the control group, the exercise group experienced significant improvements in gait speed (F(4.078) = 8.265, p = 0.007), sit to stand performance (F(3.24) = 11.033, p = 0.002) and handgrip strength (F(3.697) = 26.359, p < 0.001). Resistance training via the GrACE programme is feasible, safe and significantly improves gait speed, sit-to-stand performance and handgrip strength in RAC adults. PMID:27231652

    Mammalian skeletal muscles exhibit age-related adaptive and pathological remodeling. Several muscles in particular undergo progressive atrophy and degeneration beyond median lifespan. To better understand myocellular responses to aging, we used semi-quantitative global metabolomic profiling to characterize trends in metabolic changes between 15-month-old adult and 32-month-old aged Fischer 344 × Brown Norway (FBN) male rats. The FBN rat gastrocnemius muscle exhibits age-dependent atrophy, whereas the soleus muscle, up until 32 months, exhibits markedly fewer signs of atrophy. Both gastrocnemius and soleus muscles were analyzed, as well as plasma and urine. Compared to adult gastrocnemius, aged gastrocnemius showed evidence of reduced glycolytic metabolism, including accumulation of glycolytic, glycogenolytic, and pentose phosphate pathway intermediates. Pyruvate was elevated with age, yet levels of citrate and nicotinamide adenine dinucleotide were reduced, consistent with mitochondrial abnormalities. Indicative of muscle atrophy, 3-methylhistidine and free amino acids were elevated in aged gastrocnemius. The monounsaturated fatty acids oleate, cis-vaccenate, and palmitoleate also increased in aged gastrocnemius, suggesting altered lipid metabolism. Compared to gastrocnemius, aged soleus exhibited far fewer changes in carbohydrate metabolism, but did show reductions in several glycolytic intermediates, fumarate, malate, and flavin adenine dinucleotide. Plasma biochemicals showing the largest age-related increases included glycocholate, heme, 1,5-anhydroglucitol, 1-palmitoleoyl-glycerophosphocholine, palmitoleate, and creatine. These changes suggest reduced insulin sensitivity in aged FBN rats. Altogether, these data highlight skeletal muscle group-specific perturbations of glucose and lipid metabolism consistent with mitochondrial dysfunction in aged FBN rats. PMID:24652515

    ABSTRACT Background: We determined the association between neighborhood socio-environmental factors and insomnia symptoms in a nationally representative sample of US adults aged >50 years. Methods: Data were analyzed from two waves (2006 and 2010) of the Health and Retirement Study using 7,231 community-dwelling participants (3,054 men and 4,177 women) in the United States. Primary predictors were neighborhood physical disorder (e.g. vandalism/graffiti, feeling safe alone after dark, and cleanliness) and social cohesion (e.g. friendliness of people, availability of help when needed, etc.); outcomes were insomnia symptoms (trouble falling asleep, night awakenings, waking too early, and feeling unrested). Results: After adjustment for age, income, race, education, sex, chronic diseases, body mass index, depressive symptoms, smoking, and alcohol consumption, each one-unit increase in neighborhood physical disorder was associated with a greater odds of trouble falling asleep (odds ratio (OR) = 1.09, 95% confidence interval (CI): 1.04-1.14), waking too early (OR = 1.05, 95% CI: 1.00-1.10), and, in adults aged ≥69 years (adjusting for all variables above except age), feeling unrested in the morning (OR = 1.11, 95% CI: 1.02-1.22 in 2006). Each one-unit increase in lower social cohesion was associated with a greater odds of trouble falling asleep (OR = 1.06, 95% CI: 1.01-1.11) and feeling unrested (OR = 1.09, 95% CI: 1.04-1.15). Conclusions: Neighborhood-level factors of physical disorder and social cohesion are associated with insomnia symptoms in middle-aged and older adults. Neighborhood-level factors may affect sleep, and consequently health, in our aging population. PMID:25222023

    Age-dependent changes in the expression of group I and II metabotropic glutamate (mGlu) receptors were studied by in situ hybridization, Western blot analysis and immunohistochemistry. Male Fisher 344 rats of three ages (3, 12 and 25 months) were tested. Age-related increases in mGlu1 receptor mRNA levels were found in several areas (thalamic nuclei, hippocampal CA3) with parallel increases in mGlu1a receptor protein expression. However, a slight decrease in mGlu1a receptor mRNA expression in individual Purkinje neurons and a decline in cerebellar mGlu1a receptor protein levels were detected in aged animals. In contrast, mGlu1b receptor mRNA levels increased in the cerebellar granule cell layer. Although mGlu5 receptor mRNA expression decreased in many regions, its protein expression remained unchanged during aging. Compared to the small changes in mGlu2 receptor mRNA levels, mGlu3 receptor mRNA levels showed substantial age differences. An increased mGlu2/3 receptor protein expression was found in the frontal cortex, thalamus, hippocampus and corpus callosum in aged animals. These results demonstrate region- and subtype-specific, including splice variant specific changes in the expression of mGlu receptors in the brain with increasing age. PMID:15862522

    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.

Though several experiments have been conducted to determine the validity of this salivary component as a reliable stress marker in human subjects, the effect of stress induced changes on sAA level in different age groups is least studied. This article reports the activity of sAA in human subjects of different age groups subjected to psychological stress induced through stressful video clip. Differences in sAA level based on sex of different age groups under stress have also been studied. A total of 112 subjects consisting of both the male and female subjects, divided into two groups on basis of age were viewed a video clip of corneal transplant surgery as stressor. Activity of sAA from saliva samples of the stressed subjects were measured and compared with the activity of the samples collected from the subjects before viewing the clip. The age ranges of subjects were 18-25 and 40-60 years. The sAA level increased significantly in both the groups after viewing the stressful video. The increase was more pronounced in the younger subjects. The level of sAA was comparatively more in males than females in the respective groups. No significant change in sAA activity was observed after viewing the soothed video clip. Significant increase of sAA level in response to psychological stress suggests that it might act as a reliable sympathetic activity biochemical marker in different stages of human beings.

    A tri-algal diet was fed to three age-groups of the rainbow mussel Villosa iris: ages 2-3 d, 50-53 d, and 3-6 years. Changes in the relative abundance of each algal species were determined in 5-h feeding trials from feeding chambers and by gut content analyses. All age-groups rejected Scenedesmus quadricauda and preferentially selected Nannochloropsis oculata and Selenastrum capricornutum, principally on the basis of size. Changes in the relative abundance of algae in feeding chambers did not differ significantly among age-groups. Observed differences in the ingested quantities of the similar-sized N. oculata and S. capricornutum were attributed to other particle-related characteristics. Results indicate that the rainbow mussel can be fed similar-sized algae at ali ages in captive propagation facilities. When developing a suitable algal diet for rearing juvenile mussels, one probably need not investigate different species at each stage of development if the algae used are in the 2.8-8.5-??m size range.

    Fifty individuals with lower limb impairments including spinal cord injury, polio and amputations underwent aerobic and anaerobic arm-cranking tests in a standardized laboratory setting. Based on linear regression models applied with age as dependent variable aerobic performance variable including HRmax (R = 0.395, P = 0.004), and POaer (R = 0.31, P = 0.021) were subjected to ANCOVA adjusting for age in order to determine the significance of participation intensity (competitive vs leisure) and type of physical impairment. Anaerobic performance variables were not influenced by age and thereby subjected to 1-Way ANOVA with the same independent variables. Participation intensity and type of impairment significantly discriminated (P < 0.001) between athletes in all power variables. Linear regression models have shown moderate but significant (P < 0.001) relationship with functional ability (bases on International Wheelchair Basketball Federation classification system). In anaerobic mean power (MP) classification accounted for 42% of the variance, while in anaerobic peak power (PP) and aerobic Power (POaer) for 38% and 30% respectively. By means of a post hoc Tukey analysis significant differences were observed between athletes with a high level paraplegia (class 1) and those with one leg affected by polio or amputations (classes 4, 4.5). Athletes with low level paraplegia and two legs affected by polio (classes 2-3.5) had values in-between. Based on the descriptive evaluation, a three group scheme was conceptualized and resubjected to ANOVA. Significant intergroup differences were thus obtained only for PP. Descriptive PP data for each group were transformed into a five category table in order to provide reference values for fitness-estimation in males with lower limb impairments of various etiologies.

    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.

    The results of Sm-Nb isotopic-geochemical studies of metasedimentary and metavolcanic rocks of the Dzheltulak Group of the central part of the Dzheltulak suture, as well as geochronological U-Th-Pb (LA ICP MS) studies of detrital zircons from metasedimentary rocks, which are considered as Paleoproterozoic in current stratigraphic schemes, are presented. The age of the youngest zircons is 170-190 Ma, whereas the age of the last stage of regional metamorphism is 140-150 Ma. Thus, the Dzheltulak Group hosts metasedimentary rocks, the age of the protolith of which ranges from 140-150 to 170-190 Ma. The detrital zircons derived from intrusive and metamorphic rocks of the Selenga-Stanovoi and Dzhugdzhur-Stanovoi superterranes.

    We address the age rank of the nearest pre-main-sequence (PMS) associations, using low-resolution spectrophotometry to measure gravity-sensitive indices in these stars. We compare spectral index-colour sequences for the PMS populations and rank them according to the strength of their gravity-sensitive features. The age rank using the gravity method is in general agreement with the ranking of these groups suggested by colour-magnitude (CM) diagram placement. Several of the groups have a kinematic origin in the Oph-Sco-Cen OB association. For three of them, their age rank is also in agreement with epochs resulting from a formation scenario for the OB association.

    Exome sequencing and whole genome sequencing (ES/WGS) present individuals with the opportunity to benefit from a broad scope of genetic results of clinical and personal utility. Yet, it is unclear which genetic results people want to receive (i.e., what type of genetic information they want to learn about themselves) or conversely not receive, and how they want to receive or manage results over time. Very little is known about whether and how attitudes toward receiving individual results from ES/WGS vary among racial/ethnic populations. We conducted 13 focus groups with a racially and ethnically diverse parent population (n = 76) to investigate attitudes toward return of individual results from WGS. We report on our findings for non-African American (non-AA) participants. Non-AA participants were primarily interested in genetic results on which they could act or "do something about." They defined "actionability" broadly to include individual medical treatment and disease prevention. The ability to plan for the future was both a motivation for and an expected benefit of receiving results. Their concerns focused on the meaning of results, specifically the potential inaccuracy and uncertainty of results. Non-AA participants expected healthcare providers to be involved in results management by helping them interpret results in the context of their own health and by providing counseling support. We compare and contrast these themes with those we previously reported from our analysis of African American (AA) perspectives to highlight the importance of varying preferences for results, characterize the central role of temporal orientation in framing expectations about the possibility of receiving ES/WGS results, and identify potential avenues by which genomic healthcare disparities may be inadvertently perpetuated.

    OBJECTIVE: To evaluate the prevalence of weight excess in children and adolescents attending public and private schools of Campinas, Southeast Brazil, according to age group. METHODS: Cross-sectional study that enrolled 3,130 students from 2010 to 2012. The weight and the height were measured and the body mass index (BMI) was calculated. The students were classified by BMI Z-score/age curves of the World Health Organization (WHO)-2007 (thinness, normal weight, overweight and obesity) and by age group (7-10, 11-14 and 15-18 years). Multinomial logistic regression analysis was applied to verify variables associated to overweight and obesity. RESULTS: Among the 3,130 students, 53.7% attended public schools and 53.4% were girls. The prevalence of weight excess (overweight or obesity) was higher in private schools (37.3%) than in public ones (32.9%) and among males (37.5%), compared to females (32.7%; p<0.05). The chance of having weight excess in children aged 7-10 years was more than twice of those over 15 years old (OR 2.4; 95%CI 2.0-3.0) and it was 60% higher for the group with 11-14 years old (OR 1.6; 95%CI 1.3-2.0). The chance of being obese was three times higher in 7-10 years old children than in the adolescents with 15-18 years old (OR 4.4; 95%CI 3.3-6.4) and 130% higher than the group with 11-14 years old (OR 2.3; 95%CI 1.6-3.2). CONCLUSIONS: The prevalence of weight excess in Campinas keeps increasing at an alarming rate, especially in the younger age group. PMID:25119751

    In MRI studies, linear multi-variate methods are often employed to identify regions or connections that are affected due to disease or normal aging. Such linear models inherently assume that there is a single, homogeneous abnormality pattern that is present in all affected individuals. While kernel-based methods can implicitly model a non-linear effect, and therefore the heterogeneity in the affected group, extracting and interpreting information about affected regions is difficult. In this paper, we present a method that explicitly models and captures heterogeneous patterns of change in the affected group relative to a reference group of controls. For this purpose, we use the Mixture-of-Experts (MOE) framework, which combines unsupervised modeling of mixtures of distributions with supervised learning of classifiers. MOE approximates the non-linear boundary between the two groups with a piece-wise linear boundary, thus allowing discovery of multiple patterns of group differences. In the case of patient/control comparisons, each such pattern aims to capture a different dimension of a disease, and hence to identify patient subgroups. We validated our model using multiple simulation scenarios and performance measures. We applied this method to resting state functional MRI data from the Baltimore Longitudinal Study of Aging, to investigate heterogeneous effects of aging on brain function in cognitively normal older adults (>85years) relative to a reference group of normal young to middle-aged adults (<60years). We found strong evidence for the presence of two subgroups of older adults, with similar age distributions in each subgroup, but different connectivity patterns associated with aging. While both older subgroups showed reduced functional connectivity in the Default Mode Network (DMN), increases in functional connectivity within the pre-frontal cortex as well as the bilateral insula were observed only for one of the two subgroups. Interestingly, the subgroup

    Plastidial disproportionating enzyme1 (DPE1), an α-1,4-d-glucanotransferase, has been thought to be involved in storage starch synthesis in cereal crops. However, the precise function of DPE1 remains to be established. We present here the functional identification of DPE1 in storage starch synthesis in rice (Oryza sativa) by endosperm-specific gene overexpression and suppression. DPE1 overexpression decreased amylose content and resulted in small and tightly packed starch granules, whereas DPE1 suppression increased amylose content and formed heterogeneous-sized, spherical, and loosely packed starch granules. Chains with degree of polymerization (DP) of 6 to 10 and 23 to 38 were increased, while chains with DP of 11 to 22 were decreased in amylopectin from DPE1-overexpressing seeds. By contrast, chains with DP of 6 to 8 and 16 to 36 were decreased, while chains with DP of 9 to 15 were increased in amylopectin from DPE1-suppressed seeds. Changes in DPE1 gene expression also resulted in modifications in the thermal and pasting features of endosperm starch granules. In vitro analyses revealed that recombinant DPE1 can break down amylose into maltooligosaccharides in the presence of Glc, while it can transfer maltooligosyl groups from maltooligosaccharide to amylopectin or transfer maltooligosyl groups within and among amylopectin molecules in the absence of Glc. Moreover, a metabolic flow of maltooligosyl groups from amylose to amylopectin was clearly identifiable when comparing DPE1-overexpressing lines with DPE1-suppressed lines. These findings demonstrate that DPE1 participates substantially in starch synthesis in rice endosperm by transferring maltooligosyl groups from amylose and amylopectin to amylopectin.

    Coronary, aortic and intercranial atherosclerosis has been compared in swine maintained under the following conditions: (1) adequate food and housing but animals held in test social situations for 1 year; postmortem examination at ages of 13 to 15 months; (2) food and management designed for high productivity; postmortem examination at ages of 6 to 9 years; (3) an outdoor system of husbandry and a cooked garbage diet; postmortem examination at ages of 8 to 14 years. Extramural coronary, aortic and intracranial atherosclerosis was most advanced in swine that were fed garbage. Cerebral infarction (cerebromalacia) also was most advanced in these swine but developed in swine of the younger groups in which it was associated with atherosclerosis of small intracranial extracerebral arteries rather than with stenosis of the larger intracranial extracerebral arteries as in the oldest swine. The lesions of atherosclerosis in swine of these 3 age-groups form a continuous series and are morphologically identical with corresponding stages of atherosclerosis of man. It is concluded that swine can replace non-human primates as subjects for studies of atherosclerotic vascular disease, and that experimental designs must allow for age and behaviour patterns of the species.

    With the primary objective of attracting and retaining students from underrepresented backgrounds in the sciences, evaluation of one institution’s program has been ongoing over the past three years. Interviews with mentors in the program followed by focus groups conducted with mentees reveal key factors that shape undergraduate students’ research experiences. In the present study, attention is given to data gathered from 15 mentees in the program, the majority of whom have enrolled in community colleges, represent low socioeconomic backgrounds, and are nontraditional students. The results from focus groups with the mentees provide information on the benefits of participating in the program, characteristics of good mentors, challenges to the mentoring relationship, and the effects of underrepresented status on pursuit of advanced degrees. Comparisons of mentees’ comments about the mentoring relationship with mentors’ comments reveal similar themes and patterns while also demonstrating interesting differences. The qualitative findings are also juxtaposed with participants’ responses on the Survey of Undergraduate Research Experiences. Taken together, the data enhance our understanding of the experiences of underrepresented students in faculty-mentored research programs and highlight challenges and perspectives of students who are transferring to the university from a community college.

    Engaging in political protests are becoming increasingly common, and considering the potential, individual, costs and the low probability of affecting the political outcome, it is necessary to understand the motivations behind such actions. The desire to be part of a social group is deeply rooted in human nature, and previous research proposes that the groups one belongs to may influence the decision to engage in protests. We build on this research and suggest that social exclusion, individual fear of exclusion and need to belong interact in explaining who is likely to become engaged. In two studies, one natural experiment and one lab-experiment, we show that social exclusion increase willingness to participate in protests for individuals high in both rejection sensitivity and need to belong. We conclude that contextual factors, such as exclusion or marginalization should be considered in relation to individual level personality factors when explaining who is likely to become engaged in political protests. These results are important since they suggest that some people engage in politics simply due to social reasons and are less ideologically motivated. PMID:26031961

    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.

  14. Using Korotkoff Sounds to Detect the Degree of Vascular Compliance in Different Age Groups

    PubMed Central

    2016-01-01

    Introduction The principle behind the generation of the Korotkoff sounds is the turbulence of blood flowing through a partially occluded area in the artery. With increasing age, the vascular wall compliance is expected to decrease, which is due to the thickening of the vessel wall, due to which the amplitude of the transmitted Korotkoff sounds is decreased. There is also an accompanying rise in the systolic B.P. and pulse pressure. Aim To record and compare the amplitudes of the intermediate Korotkoff sounds and the blood pressures in individuals of the two age groups, and calculate the pulse pressure and determine whether they vary in relation to the amplitude of the intermediate Korotkoff sounds recorded. Materials and Methods The cross-sectional study was conducted on 50 young subjects (15-25 years) and 50 older subjects (50-70 years). The mid arm circumference was measured using a tape. A phonoarteriogram was placed over the left brachial artery and the sphygmomanometer cuff was tied 2cm above the cubital fossa of the left arm. The blood pressure was recorded using the Lab Tutor software. The Korotkoff sounds picked up and transmitted by the phonoarteriogram are represented as distinct lines on the graphical recording. Statistical Analysis Independent samples t-test to look for significant mean amplitude differences and for correlating mean amplitude and pulse pressure. Null hypothesis rejected at p<0.05. Data analysed using the SPSS software version 20.0 (SPSS Inc.). Results There was a significant difference in the mean amplitudes of Korotkoff sounds among the different age groups (p=0.001) and subject categories (p=0.043 among males, p=0.037 among females). A significant difference in pulse pressures was also seen among different age groups and subject categories. The decrease in the amplitudes of Korotkoff sounds in the older age group accompanies the increase in pulse pressures seen in this group and the same was seen among the different age groups within

    Background: Correlation between chronological age at different stages of cervical vertebral maturation (CVM) is important in clinical orthodontic practice. The objective of this study was to evaluate the correlation between CVM stage and chronological age in a group of Iranian female patients. Materials and Methods: This study was conducted on 196 digital lateral cephalometry of female patients with the age ranged 9-14 years. The CVM stage was determined with two calibrated examiners, using the method developed by Baccetti and its correlation with mean chronological age was assessed by the Spearman rank-order. The intra and inter-agreements were evaluated by weighted Kappa statistics in overall diagnosis of stages, in addition to determination of presence or absent of concavities at the lower border of second, third and fourth cervical vertebrae and the shapes of the third and fourth vertebrae. P < 0.05 was considered as significant. Results: The correlation coefficient between CVM stages and chronological age was relatively low (r = 0.62). The least amount of inter-observer agreement was determined to be at the clinical decision of the shape of the fourth vertebra. Conclusion: Regarding the low reported correlation, the concomitant usage of other skeletal indicators seems necessary for precise determination of physiological age of the patients. PMID:26604958

    Background The relation between serum total cholesterol (TC) and cardiovascular disease in women and in the elderly is unclear, especially in Asian populations. Methods and Results We examined this relation in the largest-scale pooled analysis of the Japanese population, the Evidence for Cardiovascular Prevention from Observational Cohorts in Japan (EPOCH-JAPAN) study. A total of 65 594 participants who were 40 to 89 years of age and did not have a past history of cardiovascular disease were examined. Cox proportional-hazards models were used to estimate hazard ratios for death from total stroke, cerebral infarction, intracranial cerebral hemorrhage, or coronary heart disease. The mean follow-up period was 10.1 years, with the number of deaths from total stroke, cerebral infarction, cerebral hemorrhage, and coronary heart disease being 875, 457, 212, and 374, respectively. The participants were divided into 2 age groups: middle-aged (40 to 69 years; mean age 55 years) and elderly (70 to 89 years; mean age 75 years). In men, the multivariate-adjusted hazard ratios for coronary heart disease in the highest TC category (≥6.21 mmol/L) compared with the lowest category (<4.14 mmol/L) were 2.52 (95% confidence interval: 1.15–5.07) in middle-aged participants and 2.77 (1.09–7.03) in elderly participants. In women, the hazard ratios of the highest TC category (≥6.72 mmol/L) compared with the lowest category (<4.66 mmol/L) were 3.20 (1.44–7.09) in middle-aged participants and 1.02 (0.42–2.49) in elderly participants. TC levels were not associated with cerebral infarction in any age or sex group and were associated negatively with total stroke and cerebral hemorrhage. Conclusion High serum TC levels are associated with coronary heart disease in middle-aged Japanese men and women, but evidence in elderly Japanese individuals is still limited. PMID:23316288

    20 college undergraduates, 25 sixth-grade, and 31 second-grade students studied targets embedded in three types of sentence contexts and then performed free recall and cued recall tests. Although there were no differences in performance of free recall among sentence types within each age group, the differences in cued recall among sentence types were observed. For sixth graders and undergraduates, both semantically congruous/syntactically congruous sentences and semantically incongruous/syntactically congruous sentences led to a better cued recall of targets than semantically incongruous/syntactically incongruous sentences. Second graders performed better in a cued recall of targets in semantically congruous/syntactically congruous sentences than for the other two sentence types. The results were interpreted as indicating changes across age groups in constraints of semantic and syntactic congruity on the spreading activation of targets in memory. PMID:11453195

    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.

    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 < 0.001 for CB, and P < 0.01 for RW), and residence in the group (P < 0.01, P < 0.01, respectively); not the maternal dominance position. Older foals reached higher dominance positions, independent of the dominance position, age, or experience of the mother; therefore, we did not find support for direct inheritance of maternal rank. Nevertheless, the foals born to the same mare in 2 consecutive seasons (n = 16 mares) revealed fair repeatability in the dominance position they obtained at 3 yr of age (intraclass correlation coefficient = 0.46). This suggests an important constant effect of the mother on the social success of her progeny; however, we did not find a significant effect of any of the tested variables describing maternal characteristics or maternal care.

    This cross sectional descriptive study was done to see the length of the right & left fallopian tube in Bangladeshi female and to increase the knowledge regarding variational anatomy in our country. Sixty post mortem specimens containing uterus, uterine tube, ureter and surrounding structures were collected by non random or purposive sampling technique from cadavers of different age groups and fixed in 10% formol saline solution. This study was carried out in the department of Anatomy of Mymensingh Medical College, Mymensingh from July 2006 to June 2007. Gross and fine dissection was carried out to study the length of fallopian tube (right & left). In this study our findings were compared with those of the standard text books. Maximum length of fallopian tube was found in middle age group (B = 13 to 45 years). It is about 9.19 cm in right side and 8.82 cm in left side. It is also important to note that more kinking was observed in middle age group. PMID:20046169

    Epidemiological studies in high income countries suggested that a big proportion of the population in Europe and America report adverse reactions to food. 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.

    In the late nineteenth and early twentieth centuries, a number of European expeditions traveled to the region of Lake Rudolf, now largely in northern Kenya. Although diverse in intent, many of these were undertaken in the interests of furthering colonial territorial claims. In 1900-1901, Major Herbert Henry Austin led a British expedition down to the lake from Khartoum in the north. Of the 62 African, Arab, and European members of this expedition, only 18 (29 %) arrived at its final destination at Lake Baringo in Kenya. Because of a confluence of adverse climatic, social, and political conditions, the expedition ran short of food supplies when it arrived at the northern end of the lake in April 1901. For the next 4 months, the members of the expedition struggled down the west side of the lake and beyond. The greatest mortality (91 %) occurred among the 32 African transport drivers who were the most marginally nourished at the outset of the trip. The lowest mortality among the Africans on the expedition (15 %) occurred among the members of the Tenth Sudanese Rifles Battalion, who had an excellent nutritional status at the start of the expedition. Major Austin himself suffered from severe scurvy with retinal hemorrhages which left him partially blind in his right eye. An analysis of the mortality rates among the groups that participated in this expedition was undertaken. This revealed that poor nutritional status at the start of the trip was predictive of death from starvation.

    Introduction: Symptomatic vaginal discharge is the most frequent symptom in women of reproductive age group. Owing to social stigma majority of affected women hesitate to seek medical consultation. Therefore the actual incidence of vaginal discharge is much more than what is reported. The aim of the study is to determine the microbiological profile of symptomatic vaginal discharge in rural area and its utility in the management of genital tract infection. Materials and Methods: This was a descriptive type of observational study, conducted in sexually active women of reproductive age group (18-45 years) attending the OPD/IPD of Obstetrics and Gynaecology Department of National Institute of Medical Sciences, Shobhanagar, Jaipur (Rajasthan), over a period of 18 months from June 2012 to December 2013. Hundred sexually active non pregnant women of reproductive age group (18-45 years) were included in the study. After taking consent general physical examination along with pelvic examination was performed. Two high vaginal swabs and blood sample were collected for various tests. Hanging drop preparation was immediately made. This was followed by gram staining and culture. Chlamydia trachomatis IgM antibody was detected by ELISA method. Results: Out of 100 women with symptomatic vaginal discharge, specific diagnosis was obtained in 89% of cases whereas no specific aetiology was found in 11% cases. Mean age was 32.60 years. Fifty-three percent patient had Bacterial vaginosis, candidiasis was found in 14% cases, 16% had Chlamydia trachomatis infection while Trichomonas vaginalis infection was detected in 6% cases. Homogenous discharge was most prevalent (52%), followed by mucopurulant discharge in 23% of women. Conclusion: Patient with symptomatic vaginal discharge need to be actively managed with appropriate antimicrobial agents. Judicious management may be helpful in prevention of HIV, HPV, CIN and post infection sequelae. PMID:25954668

    AIM To describe and compare the differences in electroretinographic responses between two different age groups of adult Dark Agouti (DA) rats and to better understand the effect of age on retinal histology and function. METHODS The electroretinographic responses of two different age groups of adult DA rats were compared. Animals were divided into younger adult DA rats 10-12wk (n=8) and older adult DA rats 17-19wk (n=8). Full field electroretinography (ERG) was recorded simultaneously from both eyes after dark adaption and light adaption and parameters including the positive scotopic threshold response (pSTR), negative scotopic threshold response (nSTR), scotopic a-wave, b-wave, photopic a-wave, b-wave and photopic negative response (PhNR) were compared between groups. RESULTS The older adult rats displayed lower stimulation thresholds of the STRs (pSTR and nSTR) and higher amplitudes of pSTR, scotopic a-wave and b-wave, photopic b-wave and PhNR amplitudes, with shorter implicit times. Photopic a-wave amplitudes were however higher in the younger adult rats. CONCLUSION In summary, for the rod system, photoreceptor, bipolar cell and RGC activity was enhanced in the older adult rats. For the cone system, RGC and bipolar cell activity was enhanced, while photoreceptor activity was depressed in the older adult rats. Such age-related selective modification of retinal cell function needs to be considered when conducting ophthalmic research in adult rats. PMID:26558198

    Purpose 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. Methods 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. Results 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. Conclusions According to the community pharmacist reports, the leading clinical manifestations and causative drugs associated with ADRs in outpatients differed among age groups. PMID:26172050

    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.

    Based on clinical psychopathology, psycho-physiological and medical tests the risk factors of professional burnout among medical professionals of all ages were revealed and the assessment of their impact on the formation of adverse functional status of physicians under research was conducted. The role of psycho-physiological factors (neuro-psychological stability, coping strategies, psychological defense mechanisms, psychosemantic self-relation space, asthenic, obsessive-phobic, hypothymic, anancastic symptoms, the dynamic characteristics of the inhibitory processes, and emotional lability) in the formation of professional burnout among medical specialists of young, middle and elderly age was defined. Neurophysiological markers of professional burnout among medical specialists of young, middle and old age, which are characterized by lower levels of reserve capacity of the cerebral cortex of alpha-rhythm, the prevalence and strength of excitation and balance of beta-rhythm were examined. It was shown that clinical examination of medical specialists of different age groups with symptoms of professional burnout should include the clinical-psychopathological and psychophysiological examinations to determine the psychopathological and personal features, psychological and emotional states of the border areas, which help to identify reactive neurotic disorders and conduct its targeted correction.

    Fetal and infant growth tends to follow irregular patterns and, particularly in developing countries, these patterns are greatly influenced by unfavorable living conditions and interactions with complications during pregnancy. The aim of this study was to identify groups of children with different risk profiles for growth development. The study sample comprised 496 girls and 508 boys under six months of age from 27 pediatric primary health care units in the city of Rio de Janeiro, Brazil. Data were obtained through interviews with the mothers and by reviewing each child's health card. An unsupervised learning, know as a self-organizing map (SOM) and a K-means algorithm were used for cluster analysis to identify groups of children. Four groups of infants were identified. The first (139) consisted of infants born exclusively by cesarean delivery, and their mothers were exclusively multiparous; the highest prevalences of prematurity and low birthweight, a high prevalence of exclusive breastfeeding and a low proportion of hospitalization were observed for this group. The second (247 infants) and the third (298 infants) groups had the best and worst perinatal and infant health indicators, respectively. The infants of the fourth group (318) were born heavier, had a low prevalence of exclusive breastfeeding, and had a higher rate of hospitalization. Using a SOM, it was possible to identify children with common features, although no differences between groups were found with respect to the adequacy of postnatal weight. Pregnant women and children with characteristics similar to those of group 3 require early intervention and more attention in public policy. PMID:24725333

    The authors' aim was to explore whether the age and the familiarity of the individuals comprising a group majority influenced the tendency of 3- and 4-year-old children to conform. Participants were presented with 2 variants of a novel task in which they were required to judge which of 3 line-drawn tigers had the greatest number of stripes. The participants made their judgments in 2 contexts, first after viewing 5 informants perform the task incorrectly, and second without viewing the responses of other individuals. The informants comprised a group of familiar children, a group of unfamiliar children, a group of familiar adults, or a group of unfamiliar adults. The results showed that the children displayed selective conformity with respect to informant age, readily adopting the incorrect response when it was indicated by an adult majority, but failing to do so when the same incorrect response was indicated by a majority of children. In contrast the familiarity of the individuals comprising the majority had little influence on the tendency of children to conform. These results suggest that children are not blanket conformists, rather they respond selectively depending on characteristics of the individuals comprising the group majority. PMID:27341477

    World Health Organization recommendations for the timing and target population for mass drug administration (MDA) for schistosomiasis are based on the prevalence of infection in school children within a given community. In a large study comparing MDA approaches for Schistosoma mansoni control, we evaluated whether prevalence of infection and egg burdens in 9- to 12-year-old students reflected infection levels in young children and adults in the same community. Cross-sectional surveys of preadolescents (9-12 years old) were compared with those of first year students (5-8 years old) in 225 villages and adults (20-55 years old) in 150 villages along the Kenyan shores of Lake Victoria. Village schistosomiasis prevalence and intensity levels in preadolescents strongly correlated (P < 0.0001) with prevalence and infection intensity for other age groups in the community. Our findings suggest that S. mansoni prevalence and intensity among 9- to 12-year-olds are valid for community sampling purposes in mapping for MDAs.

    Aims To examine the association of alcohol consumption over 10 years with cognitive performance in different socioeconomic groups. Design Prospective cohort study, the French GAZEL study. Setting France. Participants Employees of France’s national electricity and gas company. Measurements Alcohol intake was assessed annually, beginning in 1992, using questions on frequency and quantity of alcoholic beverages consumed in a week; used to define mean consumption and trajectory of alcohol intake over 10 years. Cognitive performance among participants aged ≥55 years (N=4073) was assessed in 2002–2004 using the Digit Symbol Substitution Test (DSST), a measure of psychomotor speed, attention and reasoning. Occupational position at age 35 and education were used as the markers of socioeconomic position. Findings All analyses were stratified by socioeconomic position. In the low occupational group, participants consuming a mean of more than 21 drinks per week had 2.1 points lower (95% CI: −3.9, −0.3) DSST score compared to those consuming 4–14 drinks per week. In participants with primary school education, the corresponding difference was 3.6 points (95% CI: −7.1,−0.0). No association between alcohol consumption and cognitive performance was observed in the intermediate and high socioeconomic groups, defined using either occupation or education. Analysis of trajectories of alcohol consumption showed that in the low socioeconomic groups large increase or decrease in alcohol consumption was associated with lower cognitive scores compared to stable consumption. Conclusions Our results suggest that high alcohol consumption is associated with poorer cognitive performance only in the low socioeconomic group, possibly due to greater cognitive reserve in the higher socioeconomic groups.

    The Korean experience raises questions about the assumption that successful economic development and equitable income distribution are preconditions for rapid fertility declines. During the 1960-70 decade, the total fertility rate in Korea declined by 36% and the crude birth rate fell by 33%, in the absence of significant economic development. This paper uses data from the 1974 Korean Fertility Survey to explore the relationships between the factors responsible for this rapid fertility decline. A simultaneous equation model of fertility, age at marriage, extent of labor force participation during marriage, quality of children, and wages is developed and tested. Rather than to provide definitive measures of these interrelationships, the aim was to investigate the utility of treating several variables as being jointly determined. The results suggest that parental education affects fertility by influencing age at marriage, implying that adult education programs will have little effect on marital fertility. There was some evidence that working women whose jobs are compatible with child care have more children than nonworking women, a finding that should be considered in planning increased job opportunities for women. Urbanized women and those who work before marriage tend to marry later than their less urbanized counterparts or women who do not work prior to marriage. Finally, women who used modern methods of birth control had significantly lower fertility than nonusers of modern methods. There is concern that the Government has reduced budgetary appropriations to family planning since the goal of reducing the annual population growth rate from 3% in 1960 to 2% in 1970 was achieved. It is suggested that family planning expenditures should be deployed to areas such as urban slums that have not yet been reached by family planning programs.

    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

    Independently done surveys of a target population can make an important contribution to knowledge about the determinants of personal health behavior by highlighting variables that consistently emerge as significant predictors. This investigation examined the correlates of four health practice and knowledge indices related to cardiovascular disease (CVD) in two baseline community surveys of the Pawtucket Heart Health Program (N = 2,413; N = 2,808). An additional dimension was the use of three adult age groups (18-29, 30-49, 50-64) in conducting the analyses. Results of both surveys showed that sex was the strongest correlate of the four indices--knowledge of CVD, encouraging health practice changes in others, dietary intake, and exercise. The four indices related to CVD were also associated with years of education, primary language, and whether or not a recent cholesterol measurement had been obtained, although these relationships were not as consistent as the results for sex. Overall, about half of each survey's significant associations were also found in the other survey (survey 1, 30 of 62; survey 2, 30 of 56). Consistency of significant results between surveys was best for the group ages 30-49. In either survey, it was rare for an association between a predictor and behavioral index to appear in each of the three age groups. This study supports the importance of the subjects' sex in research on personal health practices, suggests the potential for independence even among health-related indices pertinent to a single type of illness, and emphasizes the usefulness of utilizing independent samples to identify important correlates of health behavior.

    This study aimed to investigate the effects of a two-day forest therapy program on individuals with chronic widespread pain. Sixty one employees of a public organization providing building and facilities management services within the Seoul Metropolitan area participated in the study. Participants were assigned to an experimental group (n = 33) who participated in a forest therapy program or a control group (n = 28) on a non-random basis. Pre- and post-measures of heart rate variability (HRV), Natural Killer cell (NK cell) activity, self-reported pain using the visual analog scale (VAS), depression level using the Beck Depression Inventory (BDI), and health-related quality of life measures using the EuroQol Visual Analog Scale (EQ-VAS) were collected in both groups. The results showed that participants in the forest therapy group, as compared to the control group, showed physiological improvement as indicated by a significant increase in some measures of HRV and an increase in immune competence as indicated by NK cell activity. Participants in the forest therapy group also reported significant decreases in pain and depression, and a significant improvement in health-related quality of life. These results support the hypothesis that forest therapy is an effective intervention to relieve pain and associated psychological and physiological symptoms in individuals with chronic widespread pain.

    Objective This study examined how knowledge, risk perception, health beliefs and multidimensional health locus of control (HLC) were associated with caregivers’ intention to vaccinate their child, and how these associations varied across child age groups. Setting South Korea. Methods The cross-sectional survey was conducted via a face-to-face interview among 1017 nationally representative caregivers who had children aged 12 or younger. The outcome variable was caregivers’ intention to vaccinate their children. Results Hierarchical regression analysis indicated that risk perception was negatively associated with vaccination intention only among the age group 4–6 (β=−0.127, p<0.05). Perceived benefit was the only significant predictor of the outcome variables for all three age groups. In contrast, perceived barrier was negatively related to vaccination intention only among the age group 7–12 (β=−0.104, p<0.05). Internal HLC was positively related to vaccination intention only among the age group 7–12 (β=0.151, p<0.001), while chance HLC was negatively related to vaccination intention only among the age group 0–3 (β=−0.121, p<0.05). Conclusions This study identifies key vaccination intention determinants that are differentially associated with caregivers’ children's age groups. To improve vaccination rates, it suggests the need for strategies tailored to children's age. PMID:26408283

    The present research examined the hypothesis that participation in radical, but not moderate, action results in disidentification from the broader in-group. Study 1 (N = 98) was a longitudinal study conducted in the context of student protests against tuition fees in Germany and confirmed that participation in radical collective action results in disidentification with the broader in-group (students) whereas participation in moderate collective action does not. Both types of action increased politicized identification. Study 2 (N = 175) manipulated the normativeness of different types of imagined collective actions in the same context and replicated this disidentification effect for radical actions, but only when this action mismatched the broader in-group's norms. This study also indicated that these effects were partially mediated by perceived lack of solidarity and perceived lack of commitment to the cause among the broader in-group. The implications of these findings for understanding radicalization within social movements are discussed. PMID:21543649

    Little information is available concerning early specialization and competitive success in judo across the early training years. Thus, the present objective was to verify the stability of individual competitive performance of a state-level championship for judo athletes who had been previously successful. For this, 406 athletes from six age groups (9 to 20+ years old) of each sex were followed for 10 years. Using recorded data from the São Paulo State Judo Federation beginning in 1999, the scores and standings for these judo players were analyzed. The proportion of medal winners during this period was not constant, differing from the grand mean in all groups of both 204 males and 202 females. At the end of this period, only 7% of the male and 5% of the female athletes had maintained their competitive levels. Successful competitive performance in early judo competition was not associated with success later in adulthood. PMID:21987915

    Abstract Background: Relatively little is known about parents' or children's attitudes toward recruitment for, and participation in, studies of new diabetes technologies immediately after diagnosis. This study investigated factors affecting recruitment of participants for studies in newly diagnosed youth with type 1 diabetes. Methods: Qualitative focus group study incorporating four recorded focus groups, conducted in four outpatient pediatric diabetes clinics in large regional hospitals in England. Participants comprised four groups of parents (n = 22) and youth (n = 17) with type 1 diabetes, purposively sampled on the basis of past involvement (either participation or nonparticipation) in an ongoing two-arm randomized trial comparing multiple daily injection with conventional continuous subcutaneous insulin infusion regimens from the onset of type 1 diabetes. Results: Stress associated with diagnosis presents significant challenges in terms of study recruitment, with parents demonstrating varied levels of willingness to be approached soon after diagnosis. Additional challenges arise regarding the following: randomization when study arms are perceived as sharply differentiated in terms of therapy effectiveness; burdens arising from study participation; and the need to surrender new technologies following the end of the study. However, these challenges were mostly insufficient to rule out study participation. Participants emphasized the benefits and reassurance arising from support provided by staff and fellow study participants. Conclusions: Recruitment to studies of new diabetes technologies immediately after diagnosis in youth presents significant challenges, but these are not insurmountable. The stress and uncertainty arising from potential participation may be alleviated by personalized discussion with staff and peer support from fellow study participants. PMID:27355100

    [Purpose] This study determined the effects of age, gender, and participation on the benefits of a 6-month supervised exercise program on older adults. [Subjects and Methods] Eighty-five (37 women, 48 men) community-dwelling older adults participated. The chair sit-and-reach test, the 8-foot up-and-go test, the 6-minute walk test, the Berg Balance Scale, lower-body flexibility, dynamic balance, aerobic endurance, balance, metabolic rate, muscle strength, and position sense were evaluated. Repeated-measures of analysis of variance was performed including dependent variables of age, gender, and participation in the exercise program as dependent inter-subject factors and time of assessment as an intra-subject factor. [Results] Mean exercise participation was 29.88 ± 1.29 sessions. Flexibility, balance, position sense, and strength showed a significant main effect of time. There was a significant gender interaction for right shoulder flexion strength and knee extension strength, a significant gender-participation interaction for pre-/post-intervention measures of functional mobility, and a significant age-participation interaction for flexibility. [Conclusion] Exercise training improved outcomes after 6 months of supervised exercise, but the changes were similar regardless of participation level. Changes in strength were more pronounced in men than women. PMID:26157233

    Mandrills are one of the few Old World primates to show scent-marking. We combined ethological and chemical approaches to improve our understanding of this behavior in 3 zoo-managed groups. We observed the olfactory behavior performed by adults and adolescents (N = 39) for 775h. We investigated the volatile components of sternal scent-marks using gas chromatography-mass spectrometry and compared volatile profiles with traits of the signaler. Males marked more than females and within each sex the frequency of scent-marking was related to age and dominance status, but alpha males scent-marked most frequently and particularly in specific areas at the enclosure boundaries. We identified a total of 77 volatile components of sternal gland secretion, including compounds functioning as male sex pheromones in other mammals, in scent-marks spontaneously released on filter paper by 27 male and 18 female mandrills. We confirmed our previous findings that chemical profiles contain information including sex, male age and rank, and we also found that odor may encode information about group membership in mandrills. Our results support the hypotheses that scent-marking signals the status of the dominant male as well as playing territorial functions but also suggest that it is part of sociosexual communication.

    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. PMID:12179888

  3. 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'.

Two-Way ANOVA was used to find the dependency of the variables on the factor of sport skill level (A--teams which took places 1 to 4, B--places from 5 to 8; C--places from 9 to 12) and gender (F--female; M--male). Statistical significance was set at p < 0.05. The Bonferroni's adjustment was carried out for three p = 0.017 and fifteen p = 0.003 pairs of comparisons). The M and F athletes included in A-C groups (N = 48 in each group) were than compared to the classification in the neural network of Probabilistic Neural Network (PNN). A combined effect of the factors of sports level and gender on the height of attack jump (F = 4.13; p = 0.02) and block jump (F = 9.22; p < 0.001) was identified. The level of achievement was modified by the differences between the men and women. A significant advantage over the groups B and C was found for attack height and block height. In the group A, the differences between the results obtained for women and men in the ranges of attack and block with respect to the net height were not significant. Mean range of block jump did not match up to attack jump, particularly in women. The application of PNN network showed that age, BMI, relative attack jump and block jump are good predictors of sport results. The percentage of properly classified players in the group of men was lower than in women (42.4 vs. 56.3%). In this regard, big differences were found at the lower level of sport results: A (77.1 vs. 79.2%), B (25.0 vs. 25.0%) and C (25.0 vs. 64.6%). In conclusion, selection for national teams should take into consideration the players with long competitive experience with adequate weight/height ratios, who exhibit good training adaptations to jumping exercise.

    The Science Communication Working Group (SCWG) at NASA Goddard Space Flight Center (GSFC) has been in existence since late 2007. The SCWG is comprised of education and public outreach (E/PO) professionals, public affairs specialists, scientists, and engineers. The goals of the SCWG are to identify barriers to scientist and engineer engagement in E/PO activities and to enable those scientists and engineers who wish to contribute to E/PO to be able to do so. SCWG members have held meetings with scientists and engineers across GSFC to determine barriers to their involvement in E/PO. During these meetings, SCWG members presented examples of successful, ongoing E/PO projects, encouraged active research scientists and engineers to talk about their own E/PO efforts and what worked for them, discussed the E/PO working environment, discussed opportunities for getting involved in E/PO (particularly in high-impact efforts that do not take much time), handed out booklets on effective E/PO, and asked scientists and engineers what they need to engage in E/PO. The identified barriers were consistent among scientists in GSFC's four science divisions (Earth science, planetary science, heliophysics, and astrophysics). Common barriers included 1) lack of time, 2) lack of funding support, 3) lack of value placed on doing E/PO by supervisors, 4) lack of training on doing appropriate/effective E/PO for different audiences, 5) lack of awareness and information about opportunities, 6) lack of understanding of what E/PO really is, and 7) level of effort required to do E/PO. Engineers reported similar issues, but the issues of time and funding support were more pronounced due to their highly structured work day and environment. Since the barriers were identified, the SCWG has taken a number of steps to address and rectify them. Steps have included holding various events to introduce scientists and engineers to E/PO staff and opportunities including an E/PO Open House, brown bag seminars on

    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.

    Separate assessment of young-of-year (YOY) and yearling-and-older (YAO) fish is desirable from both ecological and management perspectives. Acoustic assessments provide information on fish population size structure in the target strength (TS) distribution, but interpretation of TS distributions must be done carefully, as single age groups can produce multiple TS modes. We assessed the ability of in situ TS distributions to identify Lake Champlain rainbow smelt (Osmerus mordax) age groups in June, July, and September of 2001 using mobile and stationary surveys, knowledge of vertical distribution preferences, and predicted TS from trawl catches. YAO rainbow smelt (93-179 mm total length) had wide TS distributions between -60 and -35 dB in all 3 months with two modes at approximately -50 and -40 dB. Most stationary survey single-fish tracks attributed to YAO had targets in both TS modes and a wide TS range often over 15 dB. Between June and September, YOY rainbow smelt TS increased, but single-fish tracks were unimodal, and the TS range was smaller (6 dB). Overlap in TS attributed to YOY and YAO increased from no overlap in June (YOY TS -76 to -61 dB, 15-25 mm) to moderate overlap in July (-76 to -50 dB, 25-63 mm) to considerable overlap in September (-68 to -45 dB, 33-80 mm). In June and July, the TS distribution changed abruptly at the thermocline, indicating almost complete separation of the two groups. A more gradual TS transition was evident in September, indicating substantial overlap between YOY and YAO. Separate estimates can be obtained in September by decomposing TS overlap into components attributed to YOY and YAO rainbow smelt. However, this decomposition introduces additional uncertainty and an assessment in July or possibly August is preferable to obtain separate abundance estimates of YOY and YAO. ?? 2006 Elsevier B.V.

    Free radicals have been proposed as important causative agents of ageing. The free radical theory of ageing postulates that ageing is caused by free radical reactions. These highly reactive species can cause oxidative damage in the cell. The purposive of this study was to investigate the alteration in plasma lipid peroxidation and erythrocyte superoxide dismutase activity in 2 different ethnic groups of Fars and Turkmen healthy people. We measured plasma lipid peroxidation levels (lipid peroxidation expressed as malondialdehyde) and erythrocyte superoxide dismutase activity. Study include 350 (175 Fars and 175 Turkmen male) apparently healthy individuals. Erythrocyte superoxide dismutase activities were determined in 2 different ethnic groups of Fars and Turkmen consisting of healthy individuals between 26-60 years of age {26-30 (n = 30), 3-35 (n = 30), 36-40 (n = 30), 41-45 (n = 30), 46-50 (n = 25), 51-55 (n = 15) and 56-60 (n = 15)}, respectively. The data was analyzed by Student` t-test. Erythrocyte superoxide dismutase and plasma lipid peroxidation levels in Fars and Turkmen people with 41-45 ages (group 4) and 36-40 ages (group 3) were significantly lower and higher than in the other age groups (Fars groups 1, 2 and 3, Turkmen groups 1, 2), respectively (p< 0.05). There were no significant relation between the age group 4 (Fars people) and the age groups 5, 6 and 7 (p>0.05). There were no significant relation between the age groups 3 (Turkmen people) and the age groups 4, 5, 6 and 7 (p>0.05). We found age-related differences in erythrocyte superoxide dismutase activity and plasma lipid peroxidation levels. The results indicate that the balance between antioxidant and prooxidant factors in free radical metabolism shifts towards increased lipid peroxidation with advancing age in 2 ethnic groups. This situation maybe begin in Turkmen people earlier than Fars people. The ethnic origin, diet, heavy working and life style factors of the two populations may explain

  10. Evolutionary tree design: An exploratory study of the influence of linear versus branching format on visitors' interpretation and understanding across age groups

    NASA Astrophysics Data System (ADS)

    MacDonald, Teresa Elise

    This exploratory study sought to investigate the influence of tree graphic design---specifically linear versus branching depictions of taxa---on visitors in three different age groups (aged 11-13, 14-18, adults) interpretation and understanding using a multiple-case study strategy. The findings from this research indicate that linear and branched depictions elicit qualitatively different narratives and explanations about the relationships between the taxa in all age groups. Branched tree graphics support scientifically appropriate explanations of evolutionary relationships, i.e. that taxa are related via shared or common ancestry; while linear representations reinforce intuitive interpretations of ancestor-descendant or anagenic relationships. Furthermore, differences in the language used for linear and branched trees suggests that there is a spectrum within an analogy of developmental change that is thought to serve as a transitional concept between intuitive and scientific understanding--with 'evolved from' for branched depictions of taxa representing a shift towards an interpretation of shared ancestry rather than an individual transformation from one thing into another. In addition, branched graphics appear to support the correct reading and interpretation of shared or common ancestry in tree diagrams. Mixed reasoning was common and overall reasoning patterns were broadly similar among participants in all age groups, however, older youth (aged 14 to 18) and adults often provided more detail in their explanations and sometimes included references to evolutionary ideas such as variation, inheritance and selection.

    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.

    What motivates individual self-sacrificial behavior in intergroup conflicts? Is it the altruistic desire to help the in-group or the aggressive drive to hurt the out-group? This article introduces a new game paradigm, the intergroup prisoner's dilemma-maximizing difference (IPD-MD) game, designed specifically to distinguish between these two motives. The game involves two groups. Each group member is given a monetary endowment and can decide how much of it to contribute. Contribution can be made to either of two pools, one that benefits the in-group at a personal cost and another that, in addition, harms the out-group. An experiment demonstrated that contributions in the IPD-MD game are made almost exclusively to the cooperative, within-group pool. Moreover, preplay intragroup communication increases intragroup cooperation, but not intergroup competition. These results are compared with those observed in the intergroup prisoner's dilemma game, in which group members' contributions are restricted to the competitive, between-group pool.

    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.

    The Dietary Approaches to Stop Hypertension (DASH) study was a National Heart, Lung, and Blood Institute multicenter trial that compared the impact of three dietary patterns on blood pressure (BP) among adults with high normal blood pressure or mild (Stage I) hypertension. DASH's high minority representation (two-thirds of the 459 randomized participants came from minority populations, and 60% of the cohort were African American) offered a valuable opportunity to assess factors affecting minority enrollment and retention in clinical trials of lifestyle modification. Recruitment strategies included targeted mailings to specific groups, mass mailings, community and worksite screenings, and mass media advertising; the four DASH clinical centers also reimbursed participants from $150 to $160. The most productive recruitment strategies tended to be mass mailings directed at a broad audience that was weighted toward, but not limited to, minority participants. DASH's African-American participants overwhelmingly (89%) cited health and dietary factors, such as learning more about blood pressure and healthy eating habits, as their primary reason for participating, while only six percent listed the financial incentives as their primary reason for participating. Eighty-eight percent of African-American respondents reported they would participate again in a similar study. The insights from DASH should help inform future efforts to recruit minority participants.

    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.

    The Cambridge Face Memory Test (CFMT) and Cambridge Face Perception Test (CFPT) have provided the first theoretically strong clinical tests for prosopagnosia based on novel rather than famous faces. Here, we assess the extent to which norms for these tasks must take into account ageing, sex, and testing country. Data were from Australians aged 18 to 88 years (N = 240 for CFMT; 128 for CFPT) and young adult Israelis (N = 49 for CFMT). Participants were unselected for face recognition ability; most were university educated. The diagnosis cut-off for prosopagnosia (2 SDs poorer than mean) was affected by age, participant-stimulus ethnic match (within Caucasians), and sex for middle-aged and older adults on the CFPT. We also report internal reliability, correlation between face memory and face perception, correlations with intelligence-related measures, correlation with self-report, distribution shape for the CFMT, and prevalence of developmental prosopagnosia.

    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.

    Interrelations between peculiarities of psychological profile of patients of senior age groups (according to Cattel), level of stress hormones in blood and background pathology of cardiovascular system were studied. Levels of catecholamine and corticosteroids in dynamics, rate of magnesium in erythrocytes and calcium in plaques of coronary arteries as well as fats, Holter ECG, daily profiles of blood pressure, vasomotor function of endothelium and microcirculation were analysed. It is established that stress hormones indirectly determine original form of stress reaction depending on patients' psychological profile. This contributes to the development of one or another form of cardiovascular system pathology. Excessive alcohol intake also promotes progression of cardiovascular system pathology. Depression, being a reflection of disbalance of stress hormones levels, can be used as a marker of unfavourable course of cardiovascular pathology.

    Acute abdomen in dengue, a common arboviral disease found in tropical and subtropical countries, is not uncommon and can occasionally present as acute surgical emergency requiring urgent surgical intervention. The spectrum of acute abdomen presenting as surgical emergency in dengue infection that raises suspicion of an abdominal catastrophe includes acute appendicitis, acute cholecystitis, appendicitis and, rarely, intestinal perforation. All cases of intestinal perforation including appendicular, gastric and jejunal perforation have been reported in adult patients during the course of dengue infection. However, intestinal perforation during the course of dengue infection in the paediatric age group has never been reported. We report two cases of ileal perforation in children occurring during the course of dengue infection. PMID:27485879

    Nutrient deficiencies are prevalent worldwide. Diseases and morbid conditions have been described to result from nutritional deficiencies. It is essential to address nutrient deficiencies as these may lead to chronic long-term health problems such as rickets, iron deficiency anemia, goiter, obesity, coronary heart disease, type 2 diabetes, stroke, cancer and osteoporosis. In the present review we surveyed the extent and severity of nutritional deficiencies in Israel through a selective and comprehensive Medline review of previous reports and studies performed during the last 40 years. Israeli populations have multiple nutritional deficiencies, including iron, calcium, zinc, folic acid, and vitamins B12, C, D and E, spanning all age groups, several minorities, and specific regions. In Israel, some of the nutrients are mandatorily implemented and many of them are implemented voluntarily by local industries. We suggest ways to prevent and treat the nutritional deficiencies, as a step to promote food fortification in Israel. PMID:24868510

    Elevated fractures of skull in pediatric age group are rarely reported in the literature. In view of rarity, we present a series of five cases of elevated skull fracture in pediatric age group. Over a period of 1-year, we operated on five such cases. In this article, we have discussed the mode, mechanism and extent of injury, its clinico-radiological findings, course of the disease, and the management outcome. Four out of five cases improved after surgery and did not suffer any complications. Early recognition and appropriate management of compound elevated fracture in pediatric age group comes with good outcome and prevents unwanted morbidity and mortality. PMID:26889296

    2004-01-01

    Kinetic (3-D force plate), kinematic (videography) and temporal characteristics of backstroke turns by 20 male and 16 female swimmers were recorded to identify and describe key elements of backstroke turning performance. Data were recorded during a 50 m maximum effort swim in a 25 metre pool. A Pearson product moment correlation matrix revealed that the 5 m RTT was significantly correlated with anthropometric measures of height, mass, trochanteric height and age; kinetic measures of horizontal impulse and peak force; and kinematic measures of wall contact time and peak velocity. The stepwise multiple regression equation to predict 5 m RTT was: 19.6-0.75 trochanteric height-1.8 wall exit velocity-0.03 peak vertical force. Four key factors were identified from a principle components factor analysis--anthropometry and force, post-turn velocity, force preparation and rotational skills. Implications from the findings were that age-group backstrokers should 'hit the wall hard' with relatively extended legs to reduce swim distance and push-off deceleration; use minimal wall contact time, and maximise forces to develop high horizontal velocities in a streamlined position.

    1989-12-01

    A socio-dental investigation involving a clinical examination and structured interview was carried out during 1986 on a sample of 83 people aged between 55 and 64 years in Hertfordshire. The sample was not representative of the population; subjects were employed on the staff of two retailing chains. The main purpose of the study was to estimate likely future needs of older people in such a sample. The clinical examination showed a proportion of individuals with natural and heavily restored teeth. Most subjects had one or more exposed non-carious root surfaces. The periodontal condition of the sample was favourable. Problems could occur in the future as this group ages if their currently favourable dental health deteriorates and root surfaces become carious in large numbers or the periodontal condition worsens. Conservative treatment, if required in the future, especially for housebound people, may be a problem unless domiciliary services are planned to this end. A preventive approach may help to limit operative requirements. PMID:2696575

    1983-01-01

    Thirty-six sedentary women (29-47 yr) participated in a 12-week, 4-d/week physical conditioning program (CP) involving 15-25 min/d of walking/jogging at a heart rate corresponding to 75 percent of aerobic capacity (VO2max). Twenty-three were classified obese (O, greater than 30 percent body fat, mean = 38 percent) and 13 normal (N, less than 30 percent body fat, mean = 25 percent). Significant post-CP changes included increased VO2max and decreased body fat. At 18 months post-CP a volunteer subgroup of the original 36 subjects (Ss) were re-evaluated, 19 being hydrostatically weighed, 21 exercise-tested and 28 interviewed to assess physical activity over the preceding eight quarterly periods. At CP termination 80 percent of N and 78 percent of O had intended to continue jogging, but by follow-up only 40 percent of N and 33 percent of O were so engaged, none at CP frequency, many at reduced duration and intensity. There was no significant difference between follow-up and pre-CP mean h/week of jogging for the entire follow-up group, even though eight of them (28 percent) increased their jogging over pre-CP levels. Follow-up VO2max and percent body fat means were also not significantly different from pre-CP values. It is suggested that the majority of middle-aged women participating in supervised walk-jog conditioning interventions may regress to pre-program physiologic status when left to exercise ad libitum.

    In healthcare settings, medical professionals' nonverbal behavior impacts patients' satisfaction and long-term physical, cognitive, and emotional well-being. The purpose of this research was to determine the effects of a music therapist's nonverbal behavior, affect and proximity, on participation and affect of 38 individuals with Alzheimer's disease and other related dementia (ADRD) during movement-to-music, singing, and instrument playing. Data indicated 62% of the individuals evinced positive affect when the therapist utilized affect and proximity combined, followed by the affect only condition (53%), proximity only condition (30%), and no affect or proximity condition (28%). A Friedman analysis indicated a significant difference in individuals' affect according to treatment conditions, chi(r)2 (3, 4) = 34.05, p = .001. Nonverbal behavior also impacted individuals' accuracy of participation, with participation at 79% for both affect and proximity combined, 75% for affect only, 71% for no affect or proximity, and 70% for proximity only. A significant difference occurred for participation by treatment conditions, F (3, 111) = 4.05, p = .009, eta2 = .10. Clinical implications are discussed.

    1988-01-01

    With the intensification of not-in-my-backyard (NIMBY) responses to both nuclear and chemical waste management and facility siting, we revisit public participation goals, processes, mechanisms and results to evaluate the uses and limits of public participation for achieving legitimate siting decisions. The deepening loss of trust of the American public in most institutions jeopardizes all preemptive nuclear and hazardous waste facility siting decisions, and carefully structured public participation efforts including some form of power sharing offer the best hope of devising legitimate and durable decisions. We review the key factors in the general siting milieu as well as the thickets of public participation-public involvement. Outcomes of six public participation (PP) case studies are presented and analyzed for problems as well as common factors contributing to their success or failure. The uses as well as the limits of PP in complex nuclear and hazardous waste management and siting processes are considered. 38 refs., 1 tab.

    The aim of this study was to determine whether or not sexual maturation is attained in the family group in captive-born Goeldi's monkey (Callimico goeldii) and if so, at what age and body weight. To monitor ovarian activity in 14 female Goeldi's monkeys, urinary content of pregnanediol-3alpha-glucuronide (PdG) was determined using radioimmunoassay. Urinary samples were collected between the ages of 6 and 70 weeks. Subjects became sexually mature while still housed in their family groups, at a median age of 57 weeks (48-< 70 weeks). Median body weight at the age of sexual maturity was 473 g (N=10; 420-543 g). This corresponded to 90% of the median non-pregnant body weight of breeding females in our colony (526 g, N=8). Therefore, Goeldi's monkey is similar to Leontopithecus but different from Cebuella, Callithrix, and Saguinus, in terms of daughters ovulating in the family group and at a relatively young age.

    A geochronological study of the Chocolay Group at the base of the Paleoproterozoic Marquette Range Supergroup in Michigan, Lake Superior Region, is attempted for the first time, Age data from detrital zircon grains and hydrothermal xenotime from the basal glaciogenic formation, the Enchantment Lake Formation, and the stratigraphically higher Sturgeon Quartzite and its equivalent, the Sunday Quartzite, provide maximum and minimum age constraints for the Chocolay Group. The youngest detrital zircon population in the Enchantment Lake Formation is 2317 ?? 6 Ma; in the Sturgeon Quartzite, it is 2306 ?? 9 Ma, and in the Sunday Quartzite, it is 2647 ?? 5 Ma. The oldest hydrothermal xenotime age in the Enchantment Lake Formation is 2133 ?? 11 Ma; in the Sturgeon Quartzite, it is 2115 ?? 5 Ma, and in the Sunday Quartzite, it is 2207 ?? 5 Ma. The radiometric age data in this study implies the depositional age of the Chocolay Group is constrained to ???2.3-2.2 Ga, which proves its correlation with part of the Huronian Supergroup in the Lake Huron Region, Ontario, and reveals the unconformity that separates the Chocolay Group from the overlying Menominee Group is up to 325 million years in duration. The source(s) of the ??? 2.3 Ga detrital zircon populations in the Enchantment Lake Formation and Sturgeon Quartzite remains an enigma because no known rock units of this age are known in the Michigan area. It is speculated that once widespread volcano-sedimentary cover sequences in Michigan were removed or concealed prior to Chocolay Group deposition. The hydrothermal xenotime ages probably reflect basinal hydrothermal fluid flow associated with the period of extension involving rifting and major dyke formation, that affected the North American provinces between 2.2 and 2.1 Ga. ?? 2006 NRC Canada.

  7. The importance of illness duration, age at diagnosis and the year of diagnosis for labour participation chances of people with chronic illness: results of a nationwide panel-study in the Netherlands

    PubMed Central

    2013-01-01

    Background Compared to participation rates among general populations, participation of people with chronic illness in the labour market lags behind. This is undesirable, both from the perspective of individuals’ well-being as from a macro-economic perspective for western countries where concerns exist about labour supply and sustainability of social security in the near future. To help develop successful policy measures to prevent early drop-out and support reintegration, we aimed to gain insight into the role of three age related characteristics that may relate to labour participation chances of people with chronic illness: the duration of their illness, how old they were when the chronic disease was diagnosed and the historical year in which the diagnosis was established. Methods We analyzed data of one (first) measurement of several cohorts of people diagnosed with a somatic chronic disease, who (had) participated in the Dutch ‘National Panel of people with Chronic illness or Disability’ since 1998 (N = 4634 in total). Multi-level logistic regression analyses were conducted to estimate random effects of the age at diagnosis and the year of diagnosis and fixed effects of illness duration on labour participation, while correcting for the effects of socio-demographic and disease characteristics and socio-economic indicators. Results A significant part of the variation in labour participation among people with chronic illness relates to the age they had when they were diagnosed. Furthermore, a longer illness duration is significantly associated with a lower chance of being economically active. This is more the case for men than for women. Labour participation of cancer survivors depends on the phase of the illness they find themselves in. No evidence was found that the year in which the diagnosis was established matters for employment chances later in life. Conclusion Age at diagnosis and illness duration relate to chronically ill people’s chances to

    Effective executive functions (EFs) are crucial for efficient daily functioning. Daily functioning or involvement in life situations is defined as "participation" (International Classification of Functioning, Disability, and Health [ICF]; World Health Organization, 2001). Yet associations between them have been inadequately studied for children. The present study aimed to explore the associations between EFs and child participation. Participants were 60 typically developing children aged 6 to 9 years old and their parents. The children were individually evaluated using five EF cognitive tests. The parents completed three questionnaires: the Children Participation Questionnaire, the Process Skills (the observed executive performance) Questionnaire, and the Environmental Restrictions Questionnaire. Most of the EF scores were associated with the child's age. A unique contribution of executive capacities was found for the "independence" aspect of child participation, though the quantum of contribution was limited compared with the other predictors' process skills and environmental restrictions. In the context of child participation, EFs should be studied through multivariate analysis, as otherwise, the unique contribution of executive capacities measured by neuropsychological cognitive tests are likely to be ignored. Process skills are crucial for a child's independence and autonomy in daily functioning. These findings are supported by the capacity-performance distinction suggested by the ICF model.

    Background Studies point to the lack of psychosocial support and rehabilitation services that are adjusted to the work-aged stroke survivors’ specific needs in order to promote psychosocial well-being. The aim of the study was to illuminate the psychosocial challenges work-aged participants (i.e. aged 18–67 years) thematised during and after participating a dialogue-based psychosocial intervention during the first year following a stroke. Methods The study was a feasibility study guided by the UK Medical Research Council Framework for developing and evaluating complex interventions. Qualitative data from in-depth interviews with fourteen stroke-survivors aged 33–66 years, researcher field notes and log notes written during the intervention were analysed applying a hermeneutic-phenomenological approach. Results The stroke and its consequences had a substantial impact on family and work life. Their experiences were summarised in the two themes The threat of becoming marginalised in family life and The threat of becoming marginalised in work life. Conclusion Life as a work-aged stroke survivor was experienced as challenging and created a threat of becoming marginalised in family and work life. The study highlights the need to understand the specific psychosocial challenges and needs facing work-aged stroke survivors’ in order to promote their psychosocial well-being. More research is needed concerning specific life-span challenges amongst work-aged stroke survivors in order to further develop appropriate interventions that helps address this issue. PMID:24066840

    PubMed

    Adamsen, Lis; Rasmussen, Julie Midtgaard

    2003-02-01

    Self-help groups are a growing phenomenon across national borders. Current sociologic empirical evidence shows that nurses and other healthcare professionals have become an integral part of self-help groups. The aim of the study is to describe and highlight the experiences of patients with cancer (n = 21) and oncology nurses (n = 12) with self-help groups. These experiences are drawn on to illustrate the characteristics of professional involvement in self-help groups for patients with cancer. Data were obtained by individual qualitative interviews. The results show that the nurse functions as a social networker and uses her contextual competence by consciously encouraging relationships between fellow patients. Furthermore, the study illustrates that the nurse's involvement with self-help groups for patients with cancer serves as a complementary dimension to the traditional nursing discourse. It is concluded that when individualized care is supported through social practice and when personal issues are exchanged and negotiated, the nurse facilitates a milieu of togetherness in self-help groups for patients with cancer. The concept of self-help groups is a valuable contribution to new theories and service development in psychosocial care and complies with the understanding of the postmodern individual, who viewed as primarily responsible for negotiating, socializing, and making his or her own decisions.

    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.

    The purpose of the present study was to investigate the effect of experiences of active membership and participation in decision-making processes and age on moral reasoning and goal orientations of referees in sport. The sample consisted of 148 referees of whom 56 judged soccer, 55 basketball, and 37 handball. Their ages ranged from 17 to 50 years (M=36.6, SD=7.4). Of the total number of referees, 8.3% have no experiences from active membership and participation in decision-making processes in organizations (social, athletic, political), 53.1% were simply active members, and 38.6% were involved in decision-making in their respective organizations. A two-way multivariate analysis of variance showed an interaction between experiences and age on moral reasoning and goal orientation of referees.

    2001-09-01

    During the 1998 Football World Cup Finals in France, English supporters were, once again, involved in major incidents of collective 'disorder'. Explanations for these incidents concentrated on the conflictual norms held by 'hooligans'. In contrast, Scottish supporters attending the tournament displayed norms of non-violence, explained by the popular press in terms of the absence of 'hooligans'. This study challenges this tendency to explain the presence or absence of 'disorder' in the context of football solely in terms of the presence or absence of 'hooligan' fans. Using data obtained from an ethnographic study of both Scottish and English supporters attending the tournament (N = 121), we examine the processes through which ordinarily 'peaceful' supporters would or would not become involved in collective conflict. In line with the Elaborated Social Identity Model (ESIM) of crowd behaviour, the analysis highlights the role of the intergroup context. Where out-group activity was understood as illegitimate in in-group terms, in-group members redefined their identity such that violent action toward out-group members came to be understood as legitimate. By contrast, where there was no out-group hostility, in-group members defined themselves through an explicit contrast with the 'hooligan' supporters of rival teams. This analysis represents an advance on previous studies of crowd behaviour by demonstrating how the ESIM can account for not only the presence, but also the absence, of collective 'disorder'.

    Abstract Gastric cancer (GC) remains a major killer throughout the world. Despite the dramatic decrease in GC over the last century, its etiology has not yet been well characterized. This study investigated the possible independent and combined effects of the dinner-to-bed time and post-dinner walk on the risk for GC across different age groups. A population-based, case–control study was conducted in southeast China, including 452 patients with GC and 465 age-, race-, and gender-matched controls. A self-designed questionnaire was used to collect information on demographic characteristics, dinner-to-bed time, post-dinner walk, and other behavioral factors. Conditional logistic regression models were used to estimate the effects of the dinner-to-bed time and post-dinner walk as well as their joint effect on the risk for GC across different age groups. Individuals with dinner-to-bed time <3 hours were more prone to have GC (P < 0.001), and the shorter the dinner-to-bed time was, the higher was the risk for GC (Ptrend < 0.001). Post-dinner nonwalk was associated with a 2.9-fold increased risk for GC compared with post-dinner walk (adjusted odds ratio [AOR] = 2.942, 95% confidence intervals [95% CIs] = 2.072–4.179). The interaction effect of dinner-to-bed time and post-dinner walk on GC risk was detected (AOR = 1.862, 95% CIs = 1.584–3.885, synergy index [SI] = 2.654, 95% CIs = 2.27–3.912). Participants with dinner-to-bed time <3 hours who did not walk after dinner were 7.4 times likely to suffer from GC (AOR = 7.401, 95% CIs = 4.523–13.16) than those with dinner-to-bed time ≥4 hours who took such walk. The risk of GC due to dinner-to-bed time <3 hours, post-dinner nonwalk and their interaction was positively correlated with age. The strongest risk was observed among people ≥70 years old, but the effects were not significant for people ≤55 years old. Dinner-to-bed time <3 hours and post-dinner nonwalk are

    Middle-aged and older persons living with HIV/AIDS have unique needs arising from the physical, mental, and social changes associated not only with normal aging but also related to living with a chronic illness. To address these needs, two 10-week telephone psychoeducational support groups were offered for HIV-infected persons aged 50 or older. Each group was cofacilitated by a registered nurse and a social worker; each session was 50-60 minutes every Friday; approximately 1-5 clients participated with an average number of 3 clients and there was no charge to the participants. The issues addressed in the group were: (1) staying healthy; (2) symptom management; (3) understanding other chronic illnesses; (4) understanding diagnostic tests; (5) strategies for effective interactions with the health care provider; (6) optimizing HIV/AIDS medication use; (7) understanding new developments in HIV treatment; (8) coping with losses; and (9) finding commonalities. There were unique challenges. Boundaries of respect were more difficult to maintain in a teleconference, as opposed to an in-person group. Nonverbal cues were impossible to interpret and therefore greater sensitivity was required to gauge the impact of borderline, less controlled group members, especially in relationship to other group members who may tend to be less assertive. One group member withdrew because his hearing was impaired and the telephone modality was just too challenging. It has been found that middle-aged and older adults living with HIV/AIDS with greater depression identify a need for information and support. It is crucial to share concrete information, identify symptoms clearly, and explore the use of effective and ineffective medications and treatments. The psychosocial concerns are very real and encouraging group members to open up to one another to create a cohesive community of sharing is equally important. Although the use of teleconference technology makes this more difficult, the attempt

    Introduction: Earlier, we showed that neuropathic complications limit social participation of ex-leprosy patients, even in a non-endemic leprosy setting like the Netherlands. Self-care groups for ex-leprosy patients can strengthen self-worth of participants, prevent further handicap, and enable the exchange of coping strategies. For non-endemic leprosy settings with a very low rate of leprosy patients, a self-care group exclusively for (ex)leprosy patients is not likely to be feasible. A combined group with patients facing comparable morbidity would be more efficient than disease-specific self-care groups. Here, we studied the comparability in social constraints of diabetic patients and ex-leprosy patients. Moreover, we investigated if combined self-care groups for ex-leprosy patients and diabetic patients would be desirable and acceptable for possible participants. Methods: Social participation was studied based on in-depth interviews and Participation Scale information collected from 41 diabetic patients and compared with the data of 31 ex-leprosy patients from a prior study. Moreover, we made an inventory of potential strengths and limitations and attitudes toward combined self-care groups for diabetic patients with neuropathy. Results: The following themes emerged among diabetic patients: disease confrontation, dependency, conflict with partner or relatives, feelings of inferiority, stigma, abandoning social activities, fear of the future, lack of information, and hiding the disease. These themes were very similar to those voiced by the previously interviewed ex-leprosy patients. The latter more often mentioned stigma and disease ignorance among Dutch health care workers. Whereas ex-leprosy patients perceived stigma on multiple fronts, diabetic patients only mentioned feeling inferior. Diabetic patients experienced some form of participation restriction in 39% of the cases as opposed to 71% of the ex-leprosy patients. Diabetic patients did acknowledge the

    Objective: In Brazil, demographic, socioeconomic and epidemiological changes over time have led to a transition in nutritional standards, resulting in a gradual reduction of malnutrition and an increased prevalence of overweight and obese individuals, similar to the situation in developed countries in previous decades. This study assessed the body mass index (BMI) and the prevalence of an overweight status and obesity, adjusted for various factors, in a population in northeastern Brazil including all age groups. Methods: This is a cross-sectional population-based epidemiological study using single sampling procedure composed of levels. Given the heterogeneity of the variable “income” and the relationship between income, prevalence of diseases and nutrition, a stratified sampling on blocks in the first level was used. In this, city districts were classified by income into 10 strata, according to information obtained from IBGE. A systematic sampling was applied on randomly selected blocks in order to choose the residences that would be part of the sample (second level), including 1165 participants from all age groups. Results and Discussion: The prevalence of an overweight status or obesity was adjusted for demographic, socioeconomic and lifestyle variables. When the Chi-square test was applied, a relationship was observed between the prevalence of an overweight status or obesity and the age group, gender, educational level and income of the participants. Regarding lifestyle parameters, only smoking was associated with the prevalence of an overweight status or obesity, in both adults and in the total sample. The results for the following groups were significant (p < 0.05): the age group from 20 to 59 years, when the individual presented an educational level greater than or equal to high school; and the age group ≥ 60 years, when the individual was female. It is noteworthy that educational level and being female were significant in adjusting for the total

    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.

    Asian-Americans are a small but fast-growing population in the United States who are increasingly experiencing multiple chronic diseases. While the evidence-based Chronic Disease Self-Management Program (CDSMP) has been disseminated among various racial and ethnic populations, few studies specifically investigate participants with an Asian background. The study aims to identify characteristics of middle-aged and older Asian-American CDSMP participants (older than 50 years) and investigate factors related to successful workshop completion (i.e., attending 4+ of the 6 sessions) among this population. Data were analyzed from 2,716 middle-aged and older Asian-Americans collected during a 2-year national dissemination of CDSMP. Multilevel logistic regression analyses were conducted to identify individual- and workshop-level covariates related to successful workshop completion. The majority of participants were female, living with others, and living in metro areas. The average age was 71.3 years old (±9.2), and the average number of chronic conditions was 2.0 (±1.5). Successful completion of CDSMP workshops among participants was associated with their number of chronic conditions (OR = 1.10, P = 0.011), living in non-metro areas (OR = 1.77, P = 0.009), attending workshops from area agencies on aging (OR = 1.56, P = 0.018), and attending a workshop with higher completion rates (OR = 1.03, P < 0.001). This study is the first large-scale examination of Asian-American participants enrolled in CDSMP and highlights characteristics related to intervention attendance among this under-studied minority population. Knowing such characteristics is important for serving the growing number of Asian-Americans with chronic conditions. PMID:25964933

    Hearing loss with increasing age adversely affects the ability to understand speech, an effect that results partly from reduced audibility. The aims of this study were to establish whether aging reduces speech intelligibility for listeners with normal audiograms, and, if so, to assess the relative contributions of auditory temporal and cognitive processing. Twenty-one older normal-hearing (ONH; 60–79 years) participants with bilateral audiometric thresholds ≤ 20 dB HL at 0.125–6 kHz were matched to nine young (YNH; 18–27 years) participants in terms of mean audiograms, years of education, and performance IQ. Measures included: (1) identification of consonants in quiet and in noise that was unmodulated or modulated at 5 or 80 Hz; (2) identification of sentences in quiet and in co-located or spatially separated two-talker babble; (3) detection of modulation of the temporal envelope (TE) at frequencies 5–180 Hz; (4) monaural and binaural sensitivity to temporal fine structure (TFS); (5) various cognitive tests. Speech identification was worse for ONH than YNH participants in all types of background. This deficit was not reflected in self-ratings of hearing ability. Modulation masking release (the improvement in speech identification obtained by amplitude modulating a noise background) and spatial masking release (the benefit obtained from spatially separating masker and target speech) were not affected by age. Sensitivity to TE and TFS was lower for ONH than YNH participants, and was correlated positively with speech-in-noise (SiN) identification. Many cognitive abilities were lower for ONH than YNH participants, and generally were correlated positively with SiN identification scores. The best predictors of the intelligibility of SiN were composite measures of cognition and TFS sensitivity. These results suggest that declines in speech perception in older persons are partly caused by cognitive and perceptual changes separate from age-related changes in

    Blood pressure (BP) categories defined by systolic BP (SBP) and diastolic BP (DBP) are commonly used. However, the BP category-specific risk of cardiovascular disease (CVD) has not been thoroughly investigated in different age groups. The aim of this study was to assess long-term CVD risk and its impact according to BP categories and age group. Pooling individual data from 10 cohorts, we studied 67 309 Japanese individuals (40-89 years old) who were free of CVD at baseline: we categorized them as belonging to three age groups: 'middle-aged' (40-64 years), 'elderly' (65-74 years) and 'very elderly' (75-89 years). BP was classified according to the 2009 Japanese Society of Hypertension Guidelines. Cox models were used to estimate adjusted hazard ratios for CVD deaths. We observed 1944 CVD deaths over a mean follow-up of 10.2 years. In all age groups, the overall relationship between BP category and CVD risk was positive, with a greater strength observed for younger age groups. We observed a trend of increased risk from SBP/DBP ≥ 130/85 mm Hg in the very elderly, and a significant increase from SBP/DBP ≥ 120/80 mm Hg in the other age groups. The population attributable fractions (PAFs) of CVD death in reference to the SBP/DBP<120/80 mm Hg category ranged from 23.4% in the very elderly to 60.3% in the middle-aged. We found an overall graded increase in CVD risk with higher BP category in the very elderly. The PAFs suggest that keeping BP levels low is an important strategy for primary CVD prevention, even in an elderly population.

    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.

    The current study examined associations among sports participation (SP), athletic identity (AI), weight status, and eating pathology, and whether these relations differed by gender. Data come from male and female first-year college students who participated in the Tufts Longitudinal Health Study (TLHS) between 1999-2007 (N=712). Relations among SP, AI, actual and perceived weight statuses, Eating Disorders Inventory (EDI) subscale scores, and indices of body shape concern and restrictive eating were examined with hierarchical ordinary least squares (OLS) regression. Associations between SP and eating pathology among females were moderated by perceived weight status. By contrast, relations between males' EDI subscales scores and SP were moderated by ethnicity, as well as by actual weight status. Our findings support that sports participation alone neither promotes nor protects against eating pathology among males and females.

    Abstract Objective General practitioners (GPs) and general practice registrars report work‐related stress. Balint groups may improve coping mechanisms. However, attendance at a face‐to‐face Balint group is difficult for rural doctors due to distance constraints. The study aim was to evaluate online Balint groups for rural doctors and determine effect size for a full‐scale trial. Design A mixed‐methods approach, including a pre–post controlled trial and thematic analysis of qualitative data. Setting Rural primary care. Participants Thirteen GPs and 8 general practice registrars completed the study. Interventions Balint groups were delivered over 8–9 fortnightly online sessions. GPs and GP registrars participated in separate groups. Data were collected on work‐related affect, psychological medicine skills and professional isolation using the Warr's Work‐Related Affect Scale, the Psychological Medicine Inventory, and a professional isolation scale. Main outcome measures Change scores on Warr's Work‐Related Affect Scale, the Psychological Medicine Inventory, and a professional isolation scale. Results Balint participants' scores were significantly higher post‐intervention on the Psychological Medicine Inventory (mean 6.49 (±0.20) versus 5.43 (±0.26); P < 0.01) and Warr's Work‐Related Affect (mean 4.09 (±0.09) versus 3.60 (±0.12); P < 0.01) scales than control group scores. Effect size on these scales ranged from 0.46 to 0.50. The greatest challenge was technical problems related to insufficient broadband speed. Conclusions Online Balint groups appear to improve rural doctors' psychological medicine skills and work‐related affect. New data on effect size will inform a full‐scale trial. Improved national broadband infrastructure may enhance online support opportunities for rural doctors. PMID:26114400

    The aim of this cross-sectional study was to compare the accuracy of the Cameriere European formula (Cameriere), adopted Haavikko method from 1974 (Haavikko), and revisited Demirjian method by Willems (Willems) for age estimation on orthopantomograms (OPGs) of Bosnian-Herzegovian (BH) children age groups 6-13 years. The accuracy was determined as difference between estimated dental age (DA) and chronological age (CA) and the absolute accuracy (absolute difference) was assessed by analyzing OPGs of 591 girls and 498 boys. The Cameriere method overestimated the mean age by 0.09 year for girls and underestimated by -0.02 year for boys. The Haavikko method underestimated the mean age by -0.29 year for girls and -0.09 year for boys. The Willems method overestimated the mean age by 0.24 year in girls and by 0.42 year in boys. The absolute accuracies were 0.53 year for girls and 0.55 year for boys for Cameriere method; for Haavikko method, 0.59 year for girls and 0.62 year for boys; and for Willems method 0.69 year for girls and 0.67 year for boys. In conclusion, Cameriere method is the most accurate for estimating the age of BH children age groups 6-13 years using OPGs, following adopted Haavikko method and Willems method.

    Background Homeless people have high dropout rates when they participate in therapeutic processes. The causes of this failure are not always known. This study investigates whether dropping-out is mediated by personality disorders or whether psychosocial problems are more important. Method Eighty-nine homeless people in a socio-laboral integration process were assessed. An initial interview was used, and the MCMI II questionnaire was applied to investigate the presence of psychosocial disorders (DSM-IV-TR axis IV). This was designed as an ex post-facto prospective study. Results Personality disorders were very frequent among the homeless people examined. Moreover, the high index of psychosocial problems (axis IV) in this population supported the proposal that axis IV disorders are influential in failure to complete therapy. Conclusion The outcomes of the study show that the homeless people examined presented with more psychopathological symptoms, in both axis II and axis IV, than the general population. This supports the need to take into account the comorbidity between these two types of disorder among homeless people, in treatment and in the development of specific intervention programs. In conclusion, the need for more psychosocial treatments addressing the individual problems of homeless people is supported. PMID:22151623

    Objective 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. Conclusions 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.

  13. Unintended consequences of cigarette price changes for alcohol drinking behaviors across age groups: evidence from pooled cross sections

    PubMed Central

    2012-01-01

    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. PMID:22784412

    The Pahrump Group unconformably overlies 1.35 Ga granite, is unconformably overlain by the Late Proterozoic Noonday Dolomite, and is divided into the Crystal Spring Formation, the Beck Spring Dolomite, and the Kingston Peak Formation. Contacts between these formations are gradational through several meters of interbedded clastic and carbonate rocks. Lithologic data, sedimentary structures, and fossil assemblages suggest that the Pahrump Group, from middle Crystal Spring to lower Kingston Peak time, was deposited in an intratidal to supratidal environment. Diamictite, volcanic ash, and mono lithologic megabreccia suggest that the middle and the upper members of the Kingston Peak Formation were deposited in a higher energy sedimentary and tectonic environment. Dikes and sills of 1.08 Ga diabase intrude the gneiss and all members of the Crystal Spring Formation; erosional clasts of diabase first appear in the middle Kingston Peak Formation. The diabase sills are up to 450 m thick and have caused at least 20 percent inflation of the Crystal Spring, Beck Spring, and lower Kingston Peak formations. If these sedimentary rocks were deposited at or above wave base, evidence of intraplate rifting or gross stratigraphic inflation is not recorded in the Pahrump stratigraphy until middle and upper Kingston Peak time. Therefore, the stratigraphic and petrologic data suggest that the diabase was emplaced in the Crystal Spring Formation during post-lower but pre-middle Kingston Peak time. The Beck Spring Dolomite and the lower Kingston Peak Formation are older than 1.08 Ga; the contact between the lower and the middle Kingston Peak Formation is a regional disconformity that marks significant changes in the depositional and the tectonic environments of the Pahrump Group at about 1.08 Ga.

Cross-tabulation of structural, behavioral and attitudinal variables revealed age and education were the key factors in this study's finding that the greater a person's life experience, the more favorable one's attitude toward euthanasia.

    A set of six A-type stars in the nearby Ursa Major moving group have been observed and spatially resolved with the CHARA Array, using the Classic and/or CLIMB beam combiners. At least four of these stars are rapidly rotating (vsini ≥ 170 kms-1) and are expected to be oblate. These interferometric measurements and the stars' observed photometric energy distributions (PEDs) are used to construct oblate star models from which stellar properties (R(θ), T(θ), etc.) are determined. The results are compared with MESA stellar evolution models to determine mass and age. This analysis provides an independently determined mean age estimate for the Ursa Major moving group of 490 Myr with a standard deviation of 98 Myr, consistent with previous age estimates. This validated technique can be used to provide independent age estimates of field A-stars, including those that host directly imaged substellar companions (e.g. HR 8799, κ And).

    A 60-day intervention study was conducted in which the participants took a low dose of a multivitamin and mineral supplement. The study consists of a final number of 66 volunteers (30 males and 36 females), divided into two age groups of 30-35 and 60-65 years. For 30 days they took a multivitamin and mineral supplement with 1× the recommended daily intake (RDI) followed by another 30 days with 2× the RDI. The aim of the study was to monitor oxidative stress and redox status of both young and old age groups. In serum, the expected increase of the water-soluble vitamins folate and vitamin B12 was observed with a concomitant decrease in homocysteine. Serum biomarkers of oxidative stress, the reactive oxygen metabolites, of the antioxidant status, the biological antioxidant potential did not change. However, the total thiol levels in serum, biomarker of the redox status, decreased significant, only in both groups of elderly after 60 days. In erythrocytes, there was a change in the glutathione metabolism as observed by an increase in glutathione reductase and to a lower extend in glutathione peroxidase, indicating an increase in oxidative stress in all groups. It is concluded that a low-dosed multivitamin and -mineral supplementation have different effects on the redox status in young versus old. It remained to explain why a low dose of a multivitamin and -mineral supplement cause increased oxidative stress.

    Deep neck space infections can occur at any age but require more intimate management in the paediatric age group because of their rapidly progressive nature. Concurrent abscess in distinct neck spaces has rarely been reported in healthy children. Herewith, a rare case of bilateral neck abscess is reported in a 16-month-old female and the clinical presentation and management are discussed with a review of the literature.

    Reduction of telomere length has been postulated to be a casual factor in cellular aging. Human telomeres terminate in tandemly arranged repeat arrays consisting of the (TTAGGG) motif. The length of these arrays in cells from human mitotic tissues is inversely related to the age of the donor, indicating telomere reduction with age. In addition to telemore length differences between different age cohorts, considerable variation is present among individuals of the same age. To investigate whether this variation can be ascribed to genetic influences, we have measured the size of terminal restriction fragments (TRFs) in HaeIII-digested genomic DNA from 123 human MZ and DZ twin pairs 2-95 years of age. The average rate of telomere shortening was 31 bp/year, which is similar to that observed by others. Statistical analysis in 115 pairs 2-63 years of age indicates a 78% heritability for mean TRF length in this age cohort. The individual differences in mean TRF length in blood, therefore, seem to a large extent to be genetically determined. 24 refs., 4 figs., 2 tabs.

    1980-01-01

    Due to the gradual increase in standard of living and the development of health and welfare services, man has succeeded in decreasing the death rate for all age groups with the consequent prolongation of the lifespan as a whole. On the other hand, however, the quantitative accumulation of the elderly is causing serious anxiety among all groups of people. Thus, concern about care for the aged is very high. The author is not quite so pessimistic but it is expected that there will be a qualitative improvement in the productive activities of the elderly along with an increased lifespan. Though there is not yet sufficient data to confirm improvement in the physical and mental activities of this segment of Japanese population, there are life table functions related to life expectancy, increase of mortality rate, etc. as qualitative indicators of survival or productive ability for the aged. In Japan prior to World War 2, people between 15-60 were usually regarded as the productive age population. Life expectancy of males at age 60 was 12.6 years in the 6th life tables compiled for 1935-6. The same phenomenon of prolongation of the productive age period was also recognized in connection with other values. If the borderline age dividing productive and nonproductive elderly populations will move toward a higher age in the future, the proportion of nonproductive elderly as a percentage of the total as well as of the productive population will decrease markedly as compared to when the elderly borderline is fixed at the same age. It is advised that new ways be found to allocate the expanded labor force found among this group for providing some necessary services and functions. (author's modified)

    Animal vocal signals are increasingly used to monitor wildlife populations and to obtain estimates of species occurrence and abundance. In the future, acoustic monitoring should function not only to detect animals, but also to extract detailed information about populations by discriminating sexes, age groups, social or kin groups, and potentially individuals. Here we show that it is possible to estimate age groups of African elephants (Loxodonta africana) based on acoustic parameters extracted from rumbles recorded under field conditions in a National Park in South Africa. Statistical models reached up to 70 % correct classification to four age groups (infants, calves, juveniles, adults) and 95 % correct classification when categorising into two groups (infants/calves lumped into one group versus adults). The models revealed that parameters representing absolute frequency values have the most discriminative power. Comparable classification results were obtained by fully automated classification of rumbles by high-dimensional features that represent the entire spectral envelope, such as MFCC (75 % correct classification) and GFCC (74 % correct classification). The reported results and methods provide the scientific foundation for a future system that could potentially automatically estimate the demography of an acoustically monitored elephant group or population.

    Study of the maltose/maltodextrin binding protein MalE in Escherichia coli has resulted in fundamental insights into the molecular mechanisms of microbial transport. Whether gram-positive bacteria employ a similar pathway for maltodextrin transport is unclear. The maltodextrin binding protein MalE has previously been shown to be key to the ability of group A Streptococcus (GAS) to colonize the oropharynx, the major site of GAS infection in humans. Here we used a multifaceted approach to elucidate the function and binding characteristics of GAS MalE. We found that GAS MalE is a central part of a highly efficient maltodextrin transport system capable of transporting linear maltodextrins that are up to at least seven glucose molecules long. Of the carbohydrates tested, GAS MalE had the highest affinity for maltotriose, a major breakdown product of starch in the human oropharynx. The thermodynamics and fluorescence changes induced by GAS MalE-maltodextrin binding were essentially opposite those reported for E. coli MalE. Moreover, unlike E. coli MalE, GAS MalE exhibited no specific binding of maltose or cyclic maltodextrins. Our data show that GAS developed a transport system optimized for linear maltodextrins longer than two glucose molecules that has several key differences from its well-studied E. coli counterpart.

    Sex disparities in dental caries have been observed across many populations, with females typically exhibiting higher prevalence and more affected teeth. In this study we assessed the sex disparities in two Northern Appalachian populations from West Virginia (WV, N = 1997) and Pennsylvania (PA, N = 1080) by comparing caries indices between males and females across four phases of dental development: primary dentition in children aged 1-5 years, mixed dentition in children aged 6-11 years, permanent dentition in adolescents aged 12-17 years, and permanent dentition in adults aged 18-59 years. No significant sex differences were observed for children aged 1-5 years. Contrary to national and international trends, WV girls aged 6-11 years had 1.5 fewer affected teeth than boys (p < 0.001). However, by ages 12-17, caries indices in the WV girls matched those in boys. In both WV and PA adults, women and men had similar total counts of affected teeth (i.e., DMFT), although women had more dental restorations (p < 0.001) and men had more current decay (p < 0.001). These results suggest that in some Appalachian populations, young girls benefit from protection against caries that is lost during adolescence and that adult women utilize dental health care to a greater degree than men.

  10. Calibrating the Lower Cretaceous Time Scale with U-Pb Zircon Ages from the Great Valley Group

    U-Pb dating of zircons from the Great Valley Group in northern California provides an opportunity to improve the resolution and reliability of the Early Cretaceous Time Scale and enhance its global range and applicability. Well established calcareous nannofossil and macrofossil biostratigraphy, enabled by good preservation, allows for the Great Valley Group to be anchored within the global Geologic Time Scale. Interlayered bentonites contain zircon, which when analyzed via U-Pb ID-TIMS can yield high precision ages. Our understanding of Early Cretaceous events - such as the Cretaceous Normal Polarity Super-Chron and oceanic anoxic events - will be improved by a refined time scale, particularly since the Early Cretaceous is one of the periods most lacking in high-precision radiometric points in the entire Mesozoic. Prior to this study, no U-Pb zircon analyses from the Great Valley Group involved the thermal annealing-chemical abrasion technique. Here, two new TA-CA ID-TIMS U-Pb zircon ages from the McCarty Creek section of the Great Valley Group are presented. The first bentonite is lower Valanginian, from an interval that cannot be biostratigraphically distinguished between NK-3 (Calcicalathina oblongata) and NK-4 (Cruciellipsis cuvillieri) nannofossil biozones, and four concordant dates yield an age of 137.22±0.098Ma. This age corroborates the GTS2008 lower Valanginian boundary age of 140.2Ma, and calls into question previously published Great Valley Group late Berriasian ages: 136.9±0.3Ma for a bentonite from the Stony Creek section, and 137.1±0.6Ma for a bentonite from the Grindstone Creek section. These ages appear to be too young, perhaps as a result of lead loss - the effects of which can be vastly minimized by chemical abrasion. Very preliminary results of re-dating the same aforementioned Grindstone Creek horizon yield an older age of 138.4Ma. The second bentonite is lower Aptian (Chiastozygus litterarius (NK-6) biozone) and three concordant dates yield

    The 2010 earthquake resulted in the breakdown of Haiti's social, economic and health infrastructure. Over one-quarter of a million people remain internally displaced (ID). ID women experience heightened vulnerability to intimate partner violence (IPV) due to increased poverty and reduced community networks. Scant research has examined experiences of IPV among ID women in post-earthquake Haiti. We conducted a qualitative study to explore the impact of participating in Famn an Aksyon Pou Santé Yo (FASY), a small-group HIV prevention intervention, on ID women's agency in Leogane, Haiti. We conducted four focus groups with ID women, FASY participants (n = 40) and in-depth individual interviews with peer health workers (n = 7). Our study was guided by critical ethnography and paid particular attention to power relations. Findings highlighted multiple forms of IPV (e.g., physical, sexual). Participants discussed processes of intrapersonal (confidence), interpersonal (communication), relational (support) and collective (women's rights) agency. Yet structural factors, including patriarchal gender norms and poverty, silenced IPV discussions and constrained women's agency. Findings suggest that agency among ID women is a multi-level, non-linear and incremental process. To effectively address IPV among ID women in Haiti, interventions should address structural contexts of gender inequity and poverty and concurrently facilitate multi-level processes of agency.

    In this study, we compared the efficacy of a group relapse prevention program using the cognitive behavioral therapy-based workbook, Serigaya Methamphetamine Relapse Prevention Program (SMARPP), between patients abusing the so-called "dappou drugs" (designer drug in Japan, and those abusing methamphetamine (MAP). Both groups participated in the SMARPP at the Center Hospital, National Center of Neurology and Psychiatry. Results showed that, no significant differences were found in the rates of participation in the program or self-reported frequency of drug or alcohol use between the patients abusing "dappou drugs" or MAP. However, patients using "dappou drugs" reported no significant increase in their confidence in their ability to resist the temptation to use drugs on the self- report drug abuse scales after the SMARPP intervention, while patients abusing MAP reported a significant positive difference in their ability to resist temptation. In addition, insight into substance abuse problems and motivation to participate in further treatment slightly declined in those using "dappou drugs," while there was a significant increase reported by the patients using MAP. These results suggested that the SMARPP might not be as effective for patients abusing "dappou drugs" as for those abusing MAP. The development of a relapse prevention program specifically designed for patients abusing "dappou drugs" is required. PMID:25831947

    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 (1.3%) subjects were found to have been recently infected by the virus [corrected]. 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.

    Vietnam War veterans are a sometimes overlooked subgroup of the aging baby boomer generation. Forty years after the war ended, war veterans still seek out VA or Vet Center counselors to assist with traumatic stress symptoms. However, there currently are no specific age-related protocols for treating older war veterans suffering from posttraumatic stress disorder (PTSD), nor have established PTSD interventions incorporated gerontology content for these older trauma survivors. This pilot study juxtaposed life review within regular PTSD group counseling for 12 Vietnam veterans at a community-based Vet Center using a partial crossover design. The Life Review and Experiencing Form (LREF) structured the delivery of the life review component. T-tests and repeated measures ANOVA were used to examine depression and self-assessed wisdom outcomes using measures previously tested with older adults. Findings suggest that life review prior to PTSD group therapy has clinical benefits for reducing symptoms of depression and increasing self-assessed wisdom. The study illuminates the possible relationship of traumatic stress symptom effects on the natural reminiscing process for older veterans and provides insights into methods for more age-appropriate treatment for trauma survivors participating in Vet Center and VA programs nationwide.

    The aim of this study was to describe how persons with rheumatoid arthritis (RA) of working age experience and handle their fatigue in everyday life. Six focus group discussions were conducted focusing on experiences of fatigue in 25 persons with RA (19 women, 6 men), aged 20-60 years. The discussions were recorded, transcribed verbatim, and analyzed according to qualitative content analysis. The analyses resulted in four categories. (1) Perception of fatigue: Fatigue was experienced different from normal tiredness, unpredictable, and overwhelming. It was associated with negative emotions, changed self-image, and fears. Feelings of frustration and shame were central when the persons were forced to omit valued life activities. (2) Consequences due to fatigue: The fatigue caused changes in cognitive ability, ability to act, and overall activity pattern where the increased need for rest and sleep caused an imbalance in daily life. The participants struggled not to let the fatigue interfere with work. The fatigue also brought negative consequences for their significant others. (3) Communicating fatigue: Fatigue was difficult to gain understanding for, and the participants adjusted their communication accordingly; it was important to keep up appearances. During medical consultation, fatigue was perceived as a factor not given much consideration, and the participants expressed taking responsibility for managing their fatigue symptoms themselves. (4) Strategies to handle fatigue: Strategies comprised conscious self-care, mental strategies, planning, and prioritizing. Fatigue caused considerable health problems for persons with RA of working age: negative emotions, imbalance in daily life due to increased need for rest, and difficulties gaining understanding. This draws attention to the importance of developing new modes of care to address fatigue in RA. Person-centered care to improve balance in life may be one approach needing further investigations.

    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 presence of Cretaceous detrital zircon in Upper Jurassic strata of the Great Valley Group may require revision of the lower Great Valley Group chronostratigraphy, with significant implications for the Late Jurassic-Cretaceous evolution of the continental margin. Samples (n = 7) collected from 100 km along strike in the purported Tithonian strata of the Great Valley Group contain 20 Cretaceous detrital zircon grains, based on sensitive high-resolution ion microprobe age determinations. These results suggest that Great Valley Group deposition was largely Cretaceous, creating a discrepancy between biostratigraphy based on Buchia zones and chronostratigraphy based on radiometric age dates. These results extend the duration of the Great Valley Group basal unconformity, providing temporal separation between Great Valley forearc deposition and creation of the Coast Range Ophiolite. If Great Valley forearc deposition began in Cretaceous time, then sediment by passed the developing forearc in the Late Jurassic, or the Franciscan subduction system did not fully develop until Cretaceous time. In addition to these constraints on the timing of deposition, pre-Mesozoic detrital zircon age signatures indicate that the Great Valley Group was linked to North America from its inception. ?? 2006 Geological Society of America.

    Background 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. Methods and Findings 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. Conclusion 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
