Utility of a dermatology interest group blog: the impact of medical student interest groups and Web 2.0 tools as educational resources

PubMed Central

Jalalat, Sheila Z; Wagner, Richard F

2014-01-01

The open access University of Texas Dermatology Interest Group blog was established in 2004 for the purposes of increasing communication and collaboration between medical students and dermatology faculty, residents, and alumni, as well as to promote educational opportunities and the missions for which the interest group was created. This blog is unique because of its longevity and continuous postings directed toward the educational and professional needs of medical students and residents. A blog user survey was performed to assess viewers’ thoughts, purpose of viewing, demographic profile, subscriber status, usage of the blog and other Web 2.0 tools (forums, Facebook, blogs, Twitter, podcasts), and perceived usefulness. Sixty-one anonymous online surveys were completed during a 1-month period. Statistical analyses of the responses demonstrated that the utilization of web-based tools and the blog were valuable resources for students, especially for blog subscribers, those more involved in an interest group, and those reading the blog for a longer period of time. The usefulness and impact of this method of communication and dissemination of information in medical education may encourage other student groups, faculty advisors, and educators to implement similar educational tools at their institutions.

2009-01-01

Although rural medicine interest groups (RMIGs) are prevalent in Canadian medical schools, there is little research on their contribution to rural education, training and careers. We explored 2 broad questions by means of an electronic survey to people who were RMIG participants at McMaster University from 2002 to 2007: 1) What are the experiences of undergraduate trainees in an RMIG? 2) What are the features of RMIGs that contribute to an interest in rural medicine? The survey itself contained 35 questions broken down into sections detailing demographics, involvement in RMIGs, RMIG features, core and elective experiences, careers and Canadian Resident Matching Service. Of the 63 participants who completed the survey, 13 (20.6%) were in postgraduate training and 50 (79.4%) were in undergraduate training. The mean (standard deviation) age of participants was 28.4 (6.5) years and 71.9% percent were female. Respondents indicated that rural placements had the most influence on their choice of specialty and rural interest. Of all the features and activities of the RMIG, rural medicine special events contributed the most to an interest in rural medicine (e.g., "rural medicine days"). At McMaster University, the responses of participants suggested that RMIG participation had more influence on career choice than did the medical school attended. Communities, government organizations, residency programs and others interested in improving access to rural physicians, will note the importance of RMIGs and the importance survey respondents gave to rural medicine special events and rural electives.

Pupillary Response as an Age-Specific Measure of Sexual Interest.

PubMed

Attard-Johnson, Janice; Bindemann, Markus; Ó Ciardha, Caoilte

2016-05-01

In the visual processing of sexual content, pupil dilation is an indicator of arousal that has been linked to observers' sexual orientation. This study investigated whether this measure can be extended to determine age-specific sexual interest. In two experiments, the pupillary responses of heterosexual adults to images of males and females of different ages were related to self-reported sexual interest, sexual appeal to the stimuli, and a child molestation proclivity scale. In both experiments, the pupils of male observers dilated to photographs of women but not men, children, or neutral stimuli. These pupillary responses corresponded with observer's self-reported sexual interests and their sexual appeal ratings of the stimuli. Female observers showed pupil dilation to photographs of men and women but not children. In women, pupillary responses also correlated poorly with sexual appeal ratings of the stimuli. These experiments provide initial evidence that eye-tracking could be used as a measure of sex-specific interest in male observers, and as an age-specific index in male and female observers.

A Search for Impact Debris in the Pliocene Age Sirius Group, Transantarctic Mountains

NASA Technical Reports Server (NTRS)

Harvey, Ralph P.; Boyd, Hiram

2003-01-01

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.

Intergroup conflict: individual, group, and collective interests.

PubMed

Bornstein, Gary

2003-01-01

Intergroup conflicts generally involve conflicts of interests within the competing groups as well. This article outlines a taxonomy of games, called team games, which incorporates the intragroup and intergroup levels of conflict. Its aims are to provide a coherent framework for analyzing the prototypical problems of cooperation and competition that arise within and between groups, and to review an extensive research program that has used this framework to study individual and group behavior in the laboratory. Depending on the game's payoff structure, contradictions or conflicts are created among the rational choices at the individual, group, and collective levels-a generalization of the contradiction between individual and collective rationality occurring in the traditional mixed-motive games. These contradictions are studied so as to identify the theoretical and behavioral conditions that determine which level of rationality prevails.

Impact of vocational interests, previous academic experience, gender and age on Situational Judgement Test performance.

2017-05-01

Situational Judgement Tests (SJTs) are increasingly implemented in medical school admissions. In this paper, we investigate the effects of vocational interests, previous academic experience, gender and age on SJT performance. The SJT was part of the selection process for the Bachelor's degree programme in Medicine at University of Groningen, the Netherlands. All applicants for the academic year 2015-2016 were included and had to choose between learning communities Global Health (n = 126), Sustainable Care (n = 149), Intramural Care (n = 225), or Molecular Medicine (n = 116). This choice was used as a proxy for vocational interest. In addition, all graduate-entry applicants for academic year 2015-2016 (n = 213) were included to examine the effect of previous academic experience on performance. We used MANCOVA analyses with Bonferroni post hoc multiple comparisons tests for applicant performance on a six-scenario SJT. The MANCOVA analyses showed that for all scenarios, the independent variables were significantly related to performance (Pillai's Trace: 0.02-0.47, p < .01). Vocational interest was related to performance on three scenarios (p < .01). Graduate-entry applicants outperformed all other groups on three scenarios (p < .01) and at least one other group on the other three scenarios (p < .01). Female applicants outperformed male applicants on three scenarios (p < .01) and age was positively related to performance on two scenarios (p < .05). A good fit between applicants' vocational interests and SJT scenario was related to better performance, as was previous academic experience. Gender and age were related to performance on SJT scenarios in different settings. Especially the first effect might be helpful in selecting appropriate candidates for areas of health care in which more professionals are needed.

Age Group Differences in Perceived Age Discrimination: Associations With Self-Perceptions of Aging.

PubMed

Giasson, Hannah L; Queen, Tara L; Larkina, Marina; Smith, Jacqui

2017-08-01

From midlife onwards, age stereotypes increasingly underlie social judgments and contribute to age-based discrimination. Whereas many studies compare differences between young and older adults in reports of age discrimination or sensitivity to age stereotypes, few consider age group differences among adults over 50. We form subgroups corresponding to social age group membership (early midlife, late midlife, young old, oldest old) and examine differences in reported experiences of everyday age discrimination and associations with self-perceptions of aging. Using cross-sectional and longitudinal data from the Health and Retirement Study (HRS: N = 15,071; M Age = 68, range 50-101), multivariate logistic regression was used to examine experiences of everyday discrimination attributed to age, and associations between age discrimination and self-perceptions of aging, in four age groups: early midlife, late midlife, young old, oldest old. People in the early midlife group (aged 50-59) reported more experiences of unfair treatment than the older age groups but were less likely to attribute their experiences to age discrimination. After controlling for covariates, individuals in all age groups who perceived their own aging positively were less likely to report experiences of age discrimination. The magnitude of this effect, however, was greatest in the early midlife group. Findings support proposals that midlife is a pivotal life period when individuals adjust to life events and social role transitions. Future longitudinal studies will provide further insight into whether positive self-perceptions of aging are especially important in this phase of the life course. © The Author 2017.

2018-01-01

This study aims to describe the association between dietary habits and weight status and the interest in food and science. We examined in a cross-sectional study 525 children aged between 8 and 18 years, who attended the Brussels Food Fair or the Belgian Science Day in 2013. They were divided into three groups: special interest in science, special interest in food, and a general control group. They completed a questionnaire, and body parameters were measured. The weight status of the children was identified using the growth charts and the calculated BMI. In total, 525 children were included: 290 children in the reference group, 194 in the food group, and 41 in the science group. The prevalence of overweight and obesity was 28% in the general control group, 14% in the food group, and 15% in the science group. Breakfast and dinner were skipped more often by children with overweight or obesity. Children from the food and science groups had more sweets and meat, had less fruit, and skipped less meals. In our study, 28% of the reference group had overweight or obesity. The children with special interest in food or science differed from the control group.

[Health councils, intergovernmental commissions, and interest groups in the Unified Health System

PubMed

Ribeiro

1997-01-01

Health councils have developed in Brazil in keeping with arrangements under the 1988 Constitution, and the logic of their political consensus has expanded among interest groups relevant to public policy. Collegiate bodies, such as intergovernmental commissions, represent an extension of that logic to executive relationships and also express political intermediation by expertise, following the tradition of the European Welfare State. The state technical bureaucracy has thus developed a remarkable role in policy-making and in State-level modeling of interest groups. This article argues that such collegiate bodies should be analyzed through State action and defines two models for health councils. One, the vocal political model, is characterized by a prevalence of outspoken denunciation and an overload of demands on the political agenda. The other, the consensus model, expresses self-limitation amongst interest groups in drafting demands. These models are not hierarchically fixed and are usually linked to the political platforms of interest groups participating in the collegiate bodies.

Psychiatry student interest groups: what they are and what they could be.

PubMed

Reardon, Claudia L; Dottl, Susan; Krahn, Dean

2013-05-01

Medical student interest groups across all specialties help students explore various specialties. There are no published reports on psychiatry student interest group (PSIG) curricula. The aim was to develop elements of a curriculum for such groups, based on data elicited from medical students and faculty members through a multi-institutional online survey. The authors electronically surveyed 172 United States psychiatric residency training directors to determine the activities they felt to be important for inclusion in PSIG curricula. Similarly, they surveyed U.S. medical student PSIG leaders to ascertain the activities they felt important to include in such groups, and the current content of their groups. Authors received responses from 64 program directors and 44 PSIG leaders. Based on integration of the results of both surveys, and the practices of existing groups, they propose elements of a curriculum for PSIGs. Medical student PSIG leaders are particularly interested in activities that involve residents. Other curricular topics of interest both to students and training directors include those that focus on student/physician mental health and various psychiatry subspecialties or practice settings. Training directors are willing to be involved with a wide variety of PSIG activities. The results of these surveys should help to guide PSIG leaders and faculty members in optimizing their PSIG curricula by helping them to include those activities felt to be of most interest by students and of most relevance by training directors.

Multi-age-grouping paradigm for young swimmers.

Kojima, Kosuke; Jamison, Paul L; Stager, Joel M

2012-01-01

The purpose of this study was to examine the adequacy of "multi-age" classification systems in youth sports with a specific focus on the unisex multi-age-groupings used by USA Swimming. In addition, we offer an analytical rationale for the multi-age-groupings and potential alternatives. We examined the top 100 US swim performances for three years (2005, 2006, and 2007) for girls and boys in 15 age-groups (7 to 20 years and a singular group of 21 years and older). Data for each age and sex were pooled over the three years and means were calculated for each of seven competitive swim events. Swim times differed among each age up to the 14-year age-group in girls (F (14,30885) = 183.9, P < 0.01, Cohen's d = 1.19-3.72, large effect) and 16-year age-group in boys (F (14,30885) = 308.7, P < 0.01, Cohen's d = 0.81-3.64, large effect) for all events. Age-related differences in swim times continued later in boys than girls likely due to differences between the sexes in timing of growth and maturation. Because of the differences in swim performance in contemporary multi-age-groups, stratifying swimmers by a single age is the best means to ensure competitive fairness and equality, although there is no rationale for swimmers under the age of 8 years to compete in separate unisex competitive groups.

Cosmic Dawn Science Interest Group

2016-01-01

Cosmic Dawn was identified as one of the three science objectives for this decade in the _New Worlds, New Horizons_ Decadal report, and it will likely continue to be a research focus well into the next decade. Cosmic Dawn refers to the interval during which the Universe transitioned from a nearly completely neutral state back to a nearly fully ionized state and includes the time during which the first stars formed and the first galaxies assembled.The Cosmic Dawn Science Interest Group (SIG) was formed recently under the auspices of the Cosmic Origins Program Analysis Group (COPAG). The Cosmic Dawn SIG focusses on the science cases, observations, and technology development needed to address the "great mystery" of Cosmic Origins. The reach of this SIG is broad, involving the nature of the first stars and the detectability of gamma-ray bursts at high redshifts, the extent to which the first galaxies and first supermassive black holes grew together, and the technology required to pursue these questions.For further information, consult the Cosmic Dawn SIG Web site http://cd-sig.jpl.nasa.gov/ and join the mailing list (by contacting the author).Part of this research was carried out at the Jet Propulsion Laboratory, California Institute of Technology, under a contract with the National Aeronautics and Space Administration.

Interest groups and health reform: lessons from California.

PubMed

Oliver, T R; Dowell, E B

We review the 1992 policy choices in California for expanding health insurance coverage, focusing on the rejection of an employer mandate by legislators and voters. We analyze how interest-group politics, gubernatorial politics, and national politics shaped those choices. Although public opinion and the shift of organized medicine showed considerable support for extending health insurance coverage, the opposition of liberal and conservative groups and a foundering economy prevented a significant change in public policy. The president's health reform plan appears to address many of the unresolved concerns in California, but overcoming resistance to any kind of mandate will require skilled leadership and negotiation.

GUIDANCE ON SELECTING AGE GROUPS FOR ...

EPA Pesticide Factsheets

This guidance document provides a set of early-lifestage age groups for Environmental Protection Agency scientists to consider when assessing children’s exposure to environmental contaminants and the resultant potential dose. These recommended age groups are based on current understanding of differences in behavior and physiology which may impact exposures in children. A consistent set of early-life age groups, supported by an underlying scientific rationale, is expected to improve Agency exposure and risk assessments for children by increasing the consistency and comparability of risk assessments across the Agency; by improving accuracy and transparency in assessments for those cases where current practice might too broadly combine behaviorally and physiologically disparate age groups; and by fostering a consistent approach to future exposure surveys and monitoring efforts to generate improved exposure factors for children. see description

Following three sessions at ADEE Annual Meetings, the special interest group on outreach training presents a brief report of its proceedings. Outreach, here, is clinical teaching away from the home dental school. After covering the diversity and benefits of programmes, the report considers different models and the relationship between contexts and outcomes. It concludes that: outreach provides access to additional resources; programmes prepare students for the demands of the profession; a programme's design should harmonise with both its context and its objectives; and, the educational benefits warrant the additional organisation involved. © 2011 John Wiley & Sons A/S.

Apathy in aging: are lack of interest and lack of initiative dissociable?

PubMed

Esposito, Fabienne; Rochat, Lucien; Juillerat Van der Linden, Anne-Claude; Lekeu, Françoise; Charnallet, Annik; Van der Linden, Martial

2014-01-01

Apathy is common in aging and generally defined on the basis of three dimensions: lack of initiative, lack of interest and emotional blunting. Curiously, no study until now has examined the associations and dissociations between these dimensions in elderly people (with or without dementia). These questions were addressed in two studies. In the first study, we explored the distribution of scores and the relationships between the three dimensions of apathy in 56 patients with dementia, focusing mainly on lack of initiative and lack of interest. Apathy was hetero-evaluated with the Apathy Inventory (AI), a scale widely used to assess the apathy dimensions in aging. In the second study, given the AI's limitations, we investigated in more detail the relationship between lack of initiative and interest in 115 elderly people using a new questionnaire specifically designed to assess these two dimensions. Results showed that lack of initiative was closely related to lack of interest (Study 1). Although we used a more specific questionnaire, these facets of apathy did not constitute two separable dimensions, but reflected a common main factor of apathy in aging (Study 2). Thus, the distinction between lack of initiative and lack of interest seems questionable. Only a multifactorial approach that includes the various psychological factors involved in apathy would enable one to gain a better understanding of the different manifestations of apathy and to highlight possible dissociations between them.

Ibrahim, Rose Irnawaty; Siri, Zailan

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.

Maldives. Package on population education for special interest groups developed.

PubMed

1995-01-01

The Population Education Program of the Non-Formal Education Center has developed a package of Population Education for Special Interest Groups comprising a learning package and fieldworker's guide. The learning package is especially developed for teaching population education for out-of-school populations. Special interest groups in Maldives include newly married couples, adolescents, and working youth. Produced under the guidance of UNESCO, Bangkok, the package contains 36 different materials such as posters, charts, leaflets, booklets, stories, and illustrated booklets which may be taught in 36 to 45 periods. The materials deal with eight themes, namely, family size and family welfare, population and resources, delayed marriage and parenthood, responsible parenthood, population-related values and beliefs, women in development, AIDS/STD, and respect for old people. Accompanying the learning package is the fieldworker's guide used to teach the package. It contains individual guides for each of the 36 learning materials. The guide gives the titles of the materials, format, objectives of the materials, messages, target groups, and an overview of the content of each learning materials. The methodologies used for teaching the learning materials include role playing, group discussion, questioning, brainstorming, survey, creative writing, problem-solving and evaluation. The package will be used by fieldworkers to conduct island-based population education courses. full text

Tobacco control interest groups and their influence on parliamentary committees in Canada.

PubMed

Hastie, Robyn E; Kothari, Anita R

2009-01-01

The aim of this study was to determine how tobacco control interest groups influence tobacco policy decision-making through submissions and presentations to parliamentary committees. A qualitative content analysis was used to examine the presentations and submissions on tobacco-related legislation made to parliamentary committees between 1996 and 2004. The sample was identified from the public list of tobacco-related bills tabled in both the House of Commons and the Senate; the Government of Canada website and LEGISinfo were used to determine which committee reviewed the relevant bill. Committee clerks were asked to send submissions and presentations related to specific bills identified through LEGISinfo. Submissions and presentations were scanned and entered into QSR N6 software for coding. The coding instrument was adapted from previous studies employing qualitative content analysis. Montini and Bero's recommendations were used to evaluate the submissions and presentations. Tobacco control interest groups did present scientific evidence to support tobacco control. However, they underused credible witnesses to present information at meetings. The topics presented by tobacco control interests groups were usually relevant to the bill being discussed. Tobacco control interest groups employed some of the strategies suggested by Montini and Bero in their attempt to influence parliamentary committees through submissions and presentations. They did include scientific evidence in their submissions; however, they could improve their strategies in the area of using credible witnesses, such as scientists and medical experts. Incorporating Montini and Bero's recommendations into lobbying efforts may increase success in influencing committees.

The outcome of older patients with acute myeloid leukemia (AML) remains unsatisfactory. Recent studies have shown that HLA-mismatched microtransplant could improve outcomes in such patients. To evaluate outcomes in different age groups among older patients with newly diagnosed AML who receive HLA-mismatched microtransplant. This multicenter clinical study included 185 patients with de novo AML at 12 centers in China, the United States, and Spain in the Microtransplantation Interest Group. Patients were divided into the following 4 age groups: 60 to 64 years, 65 to 69 years, 70 to 74 years, and 75 to 85 years. The study period was May 1, 2006, to July 31, 2015. Induction chemotherapy and postremission therapy with cytarabine hydrochloride with or without anthracycline, followed by highly HLA-mismatched related or fully mismatched unrelated donor cell infusion. No graft-vs-host disease prophylaxis was used. The primary end point of the study was to evaluate the complete remission rates, leukemia-free survival, and overall survival in different age groups. Additional end points of the study included hematopoietic recovery, graft-vs-host disease, relapse rate, nonrelapse mortality, and other treatment-related toxicities. Among 185 patients, the median age was 67 years (range, 60-85 years), and 75 (40.5%) were female. The denominators in adjusted percentages in overall survival, leukemia-free survival, relapse, and nonrelapse mortality are not the sample proportions of observations. The overall complete remission rate was not significantly different among the 4 age groups (75.4% [52 of 69], 70.2% [33 of 47], 79.1% [34 of 43], and 73.1% [19 of 26). The 1-year overall survival rates were 87.7%, 85.8%, and 77.8% in the first 3 age groups, which were much higher than the rate in the fourth age group (51.7%) (P = .004, P = .008, and P = .04, respectively). The 2-year overall survival rates were 63.7% and 66.8% in the first 2 age groups, which were higher than the

Differences by age groups in health care spending.

PubMed

Fisher, C R

1980-01-01

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.

Disclosure is often proposed as a strategy for handling financial conflicts of interest in medicine. Yet there has been no guidance on how clinicians should disclose potential conflicts of interest to patients. To discern patients' attitudes toward conflicts of interest in medicine and their opinions about how physicians should disclose possible conflicts in the clinical setting, we conducted six focus groups with patients recruited from three clinics in the Twin Cities area. Investigators reviewed audio recordings of the focus group discussions independently and identified themes. Maintaining patient-doctor trust was critical to all study participants. Most wanted to know only about conflicts of interest that were directly relevant to their care. In addition, most participants said physicians and other health care providers should offer patients an easy-to-read document about any conflict of interest during clinic check-ins and bring up the subject when discussing specific treatment plans for which the conflict of interest is relevant. Our study offers the first insights into patient attitudes toward and opinions about disclosure practices in clinical settings. More research into the practical aspects of managing conflicts of interest is needed as ineffective disclosure may undermine patients' trust in their doctors.

Facial Asymmetry-Based Age Group Estimation: Role in Recognizing Age-Separated Face Images.

PubMed

Sajid, Muhammad; Taj, Imtiaz Ahmad; Bajwa, Usama Ijaz; Ratyal, Naeem Iqbal

2018-04-23

Face recognition aims to establish the identity of a person based on facial characteristics. On the other hand, age group estimation is the automatic calculation of an individual's age range based on facial features. Recognizing age-separated face images is still a challenging research problem due to complex aging processes involving different types of facial tissues, skin, fat, muscles, and bones. Certain holistic and local facial features are used to recognize age-separated face images. However, most of the existing methods recognize face images without incorporating the knowledge learned from age group estimation. In this paper, we propose an age-assisted face recognition approach to handle aging variations. Inspired by the observation that facial asymmetry is an age-dependent intrinsic facial feature, we first use asymmetric facial dimensions to estimate the age group of a given face image. Deeply learned asymmetric facial features are then extracted for face recognition using a deep convolutional neural network (dCNN). Finally, we integrate the knowledge learned from the age group estimation into the face recognition algorithm using the same dCNN. This integration results in a significant improvement in the overall performance compared to using the face recognition algorithm alone. The experimental results on two large facial aging datasets, the MORPH and FERET sets, show that the proposed age group estimation based on the face recognition approach yields superior performance compared to some existing state-of-the-art methods. © 2018 American Academy of Forensic Sciences.

Interest Groups' Influence over Drug Pricing Policy Reform in South Korea

PubMed Central

Chung, Woojin

2005-01-01

In 1999, the Korean government made a drug pricing policy reform to improve the efficiency and transparency of the drug distribution system. Yet, its policy formation process was far from being rational. Facing harsh resistance from various interest groups, the government changed its details into something different from what was initially investigated and planned. So far, little evidence supports any improvement in Korea's drug distribution system. Instead, the new drug pricing policy has deteriorated Korea's national health insurance budget, indicating a heavier economic burden for the general public. From Korea's experience, we may draw some lessons for the future development of a better health care system. As a society becomes more pluralistic, the government should come out of authoritarianism and thoroughly prepare in advance for resistance to reform, by making greater efforts to persuade strong interest groups while informing the general public of potential benefits of the reform. Additionally, facing developing civic groups, the government should listen but not rely too much on them at the final stage of the policy formation. Many of the civic groups lack expertise to evaluate the details of policy and tend to act in a somewhat emotional way. PMID:15988802

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

Vocational interests predict educational and career choices, job performance, and career success (Rounds & Su, 2014). Although sex differences in vocational interests have long been observed (Thorndike, 1911), an appropriate overall measure has been lacking from the literature. Using a cross-sectional sample of United States residents aged 14 to 63 who completed the Strong Interest Inventory assessment between 2005 and 2014 (N = 1,283,110), I examined sex, age, ethnicity, and year effects on work related interest levels using both multivariate and univariate effect size estimates of individual dimensions (Holland's Realistic, Investigative, Artistic, Social, Enterprising, and Conventional). Men scored higher on Realistic (d = -1.14), Investigative (d = -.32), Enterprising (d = -.22), and Conventional (d = -.23), while women scored higher on Artistic (d = .19) and Social (d = .38), mostly replicating previous univariate findings. Multivariate, overall sex differences were very large (disattenuated Mahalanobis' D = 1.61; 27% overlap). Interest levels were slightly lower and overall sex differences larger in younger samples. Overall sex differences have narrowed slightly for 18-22 year-olds in more recent samples. Generally very small ethnicity effects included relatively higher Investigative and Enterprising scores for Asians, Indians, and Middle Easterners, lower Realistic scores for Blacks and Native Americans, higher Realistic, Artistic, and Social scores for Pacific Islanders, and lower Conventional scores for Whites. Using Prediger's (1982) model, women were more interested in people (d = 1.01) and ideas (d = .18), while men were more interested in things and data. These results, consistent with previous reviews showing large sex differences and small year effects, suggest that large sex differences in work related interests will continue to be observed for decades.

The influence and ethics of interest groups on policy incentives for clean energy development

NASA Astrophysics Data System (ADS)

Maguire, Mariana C.

The clean energy revolution in the United States is not going to happen until diverse stakeholders in the coalition of clean energy proponents strengthen their cohesion and influence—two critical tools for interest group's to be successful in driving the formulation of public policy. Currently, clean energy technology and resource development is supported by a highly diverse coalition of interest groups such as environmental groups, health organizations, industry, and the Defense Department, whose primary goals are often unrelated. Yet their objectives are increasingly well served by pursuing clean energy development by pushing lawmakers for supportive policies. However, characteristics of this ad hoc coalition can hinder its influence and cohesion. Whereas, fossil fuel interests—exemplified by the coalition of oil proponents—are highly cohesive and influential. This thesis will analyze whether there is a correlation between public policies on clean energy, and the strength of interest group influence over those policy decisions. It will begin with an analysis of interest group theories. Next it will analyze the histories of the oil industry as the model opponent of clean energy policies, and the biofuels, wind energy, and solar energy industries as the model proponents of clean energy policies. The composition of the respective coalitions will reveal if they are diverse or similar, with broad or narrow goals, and other important characteristics. Their respective policy positions and messages will show what values are important to them, and the presidential support each coalition has been achieved, or failed to achieve, will provide further insight into their effectiveness. This thesis will then apply interest group theories to the supporter and opponent coalitions. Results obtained indicate that the coalition of oil interests is large, yet very cohesive and influential, while the coalition for clean energy is large, generally diffuse but with some important

Going for the cure: patient interest groups and health advocacy in the United States.

PubMed

Keller, Ann C; Packel, Laura

2014-04-01

Citizen groups, though celebrated during their sudden arrival on the lobbying scene, are vastly outnumbered by groups representing elite, occupationally based interests. Sensitive to the odds that nonoccupational groups face, this study asks what factors have allowed patient groups to form and become active in federal politics. Using three distinct data sets--a survey of patient groups, content analysis of group websites, and in-depth interviews with group representatives and policy makers in Washington, DC--this study assesses the activities of patient groups in the United States and argues that patient advocacy organizations garner stability from the relatively easy provision of selective and solidary benefits. Larger patient groups are especially likely to make use of these structural advantages to pursue congressional lobbying strategies. However, even these groups seek out noncompetitive, distributive political environments. Moreover, the study finds that patient groups rarely form coalitions across diseases, forgoing the potential to collectively speak for shared patient interests.

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

Kallery, Maria; Loupidou, Thomais

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.

An important challenge in Web-based health promotion is to increase the reach of the target audience by taking the target groups' desires into consideration. Data from 505 members of a Dutch Internet panel (representative for Dutch Internet users) were used to asses the target group's interests and needs. 28% participated in Web-based tailored lifestyle programs, 57% expressed an interest in such programs, and 15% expressed no interest. Interest in Web-based programs was predominantly caused by a general interest in lifestyle and online tests. Participation in Web-based tailored lifestyle programs should not take more than 17 minutes per occasion. 84% were interested in follow-up testing after the initial participation. Responders were particularly interested in physical activity and nutrition. Hardly anyone was willing to pay for participation. The results from this study support the use of Web-based tailored lifestyle programs in behavior change efforts.

Redefining meaningful age groups in the context of disease.

PubMed

Geifman, Nophar; Cohen, Raphael; Rubin, Eitan

2013-12-01

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

This article examines some of the story conventions of network television news to explain the ways in which healthcare interest groups develop and maintain their presence in this medium - a process that has significant implications for public understanding of healthcare issues, and therefore to bioethics. The article is divided into three sections. The first section focuses on three major normative conventions of television news: adherence to a simple narrative structure, the balance ethic, and avoidance of the "think-piece" and outlines the basic strategies available to interest groups for exploiting these normative conventions. Section two introduces three case studies of organizations and individuals who have run high-profile media campaigns. Section three explores the implications for bioethics of the observations made in this article.

Malaria is still one of the problem of community health in Sumatera. This study was carried out to compare RDT accuracy in some groups of age in hypoendemic malaria. The microscopy test was investigated by 3% Giemsa Staining and examined by a trained laboratory technician. RDT was carried out by using Monotes Test Drive. The accuracy of RDT diagnostic was commonly significant in all groups of age, exceptin thegroup of age > 65 years old (p=0.393). The highest sensitivity of RDT was commonly inagroup of age ≤ 5 years old and decreased in the older group of age. Otherwise, the lowest specificity was found in agroup of age ≤ 5 years old and the highest in agroup of age 6-15 years old.The highest PPV and NPV was found inagroup of age 16-65 years old and ≤ 5 years old, respectively. The highest of parasite density was found in a group of age ≤ 5 years old (644.4±494.5parasite/μl) and the lowest in agroup of age > 65 years (400±490.71parasite/μl). The accurate diagnosis of RDT reduces by increasing of age.

Synchrotron-based XRD spectra from rat bone of different age groups (w, 56 w and 78w), lumber vertebra at early stages of bone formation, Calcium hydroxyapatite (HAp) [Ca 10 (PO 4 ) 6 (OH) 2 ] bone fill with varying composition (60% and 70%) and bone cream (35-48%), has been acquired with 15keV synchrotron X-rays. Experiments were performed at Desy, Hamburg, Germany, utilizing the Resonant and Diffraction beamline (P9), with 15keV X-rays (λ=0.82666 A 0 ). Diffraction data were quantitatively analyzed using the Rietveld refinement approach, which allowed us to characterize the structure of these samples in their early stages. Hydroxyapatite, received considerable attention in medical and materials sciences, since these materials are the hard tissues, such as bone and teeth. Higher bioactivity of these samples gained reasonable interest for biological application and for bone tissue repair in oral surgery and orthopedics. The results obtained from these samples, such as phase data, crystalline size of the phases, as well as the degree of crystallinity, confirm the apatite family crystallizing in a hexagonal system, space group P6 3 /m with the lattice parameters of a=9.4328Å and c=6.8842Å (JCPDS card #09-0432). Synchrotron-based XRD patterns are relatively sharp and well resolved and can be attributed to the hexagonal crystal form of hydroxyapatite. All the samples were examined with scanning electron microscope at an accelerating voltage of 15kV. The presence of large globules of different sizes is observed, in small age groups of the rat bone (8w) and lumber vertebra (LV), as distinguished from, large age groups (56 and 78w) in all samples with different magnification, reflects an amorphous phase without significant traces of crystalline phases. Scanning electron microscopy (SEM) was used to characterize the morphology and crystalline properties of Hap, for all the samples, from 2 to 100μm resolution. Copyright © 2017 Elsevier B.V.

Setting the Record Straight: Interest Group Influence on Climate Policy at the Environmental Protection Agency

NASA Astrophysics Data System (ADS)

Cook, Jeffrey J.

It is clear that interest groups are involved in the rulemaking process at the Environmental Protection Agency (EPA), but it has been difficult to determine whether certain groups are more influential on outcomes. This debate persists because the literature illustrates that groups can be influential at discrete stages in the process, but the field rarely analyzes the entire rulemaking process. This uncertainty has spurred controversy regarding the EPA's recent climate change regulations. Therefore, this dissertation conducted three case studies of recent climate change regulations and addresses three questions. First, what, if any, strategies did interest groups use to influence the content of these climate change rules? Second, did these strategies translate into influence? Third, what can these climate change case studies tell us about the role of interest groups in other controversial rules at the EPA, and across the bureaucracy more broadly? Ultimately, I argue that interest group influence was generally balanced across each of the three case studies. These findings then serve as the basis to develop my Regulatory Spheres of Influence Framework. The framework illustrates that given the nature of EPA rulemakings, it is very difficult for one side either business or environmental to dominate the process in highly controversial rules. It is possible that these conclusions track to other controversial rules across the bureaucracy and I note that my framework could be applied in other contexts to test this assertion.

On first contact, students express less interest in plants than in animals. With suitable didactic methods, however, the teacher can actively interest students in plants. In our research we attempted to quantify the influence of these methods. 184 students of three age groups took part in the experiment. We used eight plants (one artificial). We…

To evaluate consumers' interest in pharmacist-provided human immunodeficiency virus (HIV) screening and to evaluate potential barriers and facilitators to HIV screening in the community pharmacy setting. Cross-sectional survey of adult patients who presented to one of five community (chain and independent) pharmacies from November 2010 to August 2011. Based on 380 usable surveys, 135 (35.8%) participants were interested in pharmacy-based HIV screening. Independent predictors of interest in HIV screening identified in multivariate analysis (reference groups: ages 30 to 49 years old and white, non-Hispanic race) included younger age (18 to 29 years old) (odds ratio [OR], 2.48; 95% confidence interval [CI], 1.31 to 4.71); black, non-Hispanic race (OR, 2.37; CI, 1.40 to 4.03); and other race (OR, 4.58; CI, 1.63 to 12.87). Lack of perceived risk for HIV was the most commonly cited barrier to HIV screening; and free, rapid, or confidential HIV testing were identified as potential facilitators. Interest in pharmacy-based HIV screening was high among participants representing age and race groups disproportionately affected by HIV. Expansion of HIV screening efforts to community pharmacies warrants further consideration.

Screens for developmental delay generally provide a set of norms for different age groups. Development varies continuously with age, however, and applying a single criterion for an age range will inevitably produce misclassifications. In this report, we estimate the resulting error rate for one example: the cognitive subscale of the Bayley Scales of Infant and Toddler Development (BSID-III). Data come from a general population sample of 594 children (305 male) aged 1 month to 42.5 months who received the BSID-III as part of a validation study. We used regression models to estimate the mean and variance of the cognitive subscale as a function of age. We then used these results to generate a dataset of one million simulated participants and compared their status before and after division into age groups. Finally, we applied broader age bands used in two other instruments and explored likely validity limitations when different instruments are compared. When BSID-III age groups are used, 15% of cases are missed and 15% of apparent cases are false positives. Wider age groups produced error rates from 27% to 46%. Comparison of different age groups suggests that sensitivity in validation studies would be limited, under certain assumptions, to 70% or less. The use of age groups produces a large number of misclassifications. Although affected children will usually be close to the threshold, this may lead to misreferrals. Results may help to explain the poor measured agreement of development screens. Scoring methods that treat child age as continuous would improve instrument accuracy.

Our clinical experience showed that there has been no decrease in pediatric cases of acute viral hepatitis in Kathmandu. The objective of the study was to analyze the etiology, clinical features, laboratory parameters, sonological findings and other to determine the probable prognostic factors of Acute Viral Hepatitis in pediatric population. Consecutive patients of suspected Acute Viral Hepatitis, below the age of 15 years, attending the liver clinic between January 2006 and December 2010 were studied. After clinical examination they were subjected to blood tests and ultrasound examination of abdomen. The patients were divided in 3 age groups; 0-5, 5-10 and 5-15 years. Clinical features, laboratory parameters, ultrasound findings were compared in three age groups. Etiology of Acute Viral Hepatitis was Hepatitis A virus 266 (85%), Hepatitis E virus in 24 (8%), Hepatitis B virus in 15 (5%). In 7(2%) patients etiology was unknown. Three patients went to acute liver failure but improved with conservative treatment. There was no statistical difference in most of the parameters studied in different age groups. Ascites was more common in 5-10 years age group. Patients with secondary bacterial infection, ultrasound evidence of prominent biliary tree and ascites were associated with increased duration of illness. Patients with history of herbal medications had prolonged cholestasis. Hepatitis A is most common cause of Acute Viral Hepatitis in pediatric population. Improper use of herbal medications, secondary bacterial infection and faulty dietary intake was associated with prolonged illness. Patients with prominent biliary radicals should be treated with antibiotics even with normal blood counts for earlier recovery.

U.S. Geological Survey Karst Interest Group Proceedings, Bowling Green, Kentucky, May 27-29, 2008

States are developed in carbonate rocks and karst areas. These aquifers and the springs that discharge from them, serve as major water-supply sources and as unique biological habitats. Commonly, there is competition for the water resources of karst aquifers, and urban development in karst areas can impact the ecosystem and water quality of these aquifers. The concept for developing a Karst Interest Group evolved from the November 1999 National Ground-Water Meeting of the U.S. Geological Survey (USGS), Water Resources Division. As a result, the Karst Interest Group was formed in 2000. The Karst Interest Group is a loose-knit grass-roots organization of USGS employees devoted to fostering better communication among scientists working on, or interested in, karst hydrology studies. The mission of the Karst Interest Group is to encourage and support interdisciplinary collaboration and technology transfer among USGS scientists working in karst areas. Additionally, the Karst Interest Group encourages cooperative studies between the different disciplines of the USGS and other Department of Interior agencies and university researchers or research institutes. The first Karst Interest Group workshop was held in St. Petersburg, Florida, February 13-16, 2001, in the vicinity of karst features of the Floridan aquifer system. The proceedings of that first meeting, Water-Resources Investigations Report 01-4011 are available online at: http://water.usgs.gov/ogw/karst/ The second Karst Interest Group workshop was held August 20-22, 2002, in Shepherdstown, West Virginia, in close proximity to the carbonate aquifers of the northern Shenandoah Valley. The proceedings of the second workshop were published in Water-Resources Investigations Report 02-4174, which is available online at the previously mentioned website. The third workshop of the Karst Interest Group was held September, 12-15, 2005, in Rapid City, South Dakota, which is in close proximity to karst features

2017-08-01

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

The “Molecular Imaging in Nanotechnology and Theranostics” (MINT) Interest Group of the World Molecular Imaging Society (WMIS) was founded in 2015 and was officially inaugurated during the 2016 World Molecular Imaging Conference (WMIC). The MINT interest group was created in response to the exponential growth of the fields of Nanotechnology and Theranostics in recent years, and the resulting need to provide a more organized and focused forum on these topics at the WMIS and the WMIC. The overarching goal of MINT is to bring together the many scientists who work on molecular imaging approaches using nanotechnology, and those that work on theranostic agents. MINT therefore represents scientists, labs, and institutes that are very diverse in their scientific backgrounds and areas of expertise, reflecting the wide array of materials and approaches that drive these fields. In this short review, we attempt to provide a condensed overview over some of the key areas covered by MINT. Given the breadth of the fields and the given space constraints, we have limited the coverage to the realm of nano-constructs, although theranostics is certainly not limited to this domain. We will also focus only on the most recent developments of the last 3-5 years, in order to provide the reader with an intuition of what is “in the pipeline” and has potential for clinical translation in the near future.

Ethically and legally, assertions that resuscitation is in a patient's best interest should be inversely correlated with willingness to forego intensive care (and accept comfort care) at the surrogate's request. Previous single country studies have demonstrated a relative devaluation of neonates when compared with other critically ill patients. In this international study, physicians in Argentina, Australia, Canada, Ireland, The Netherlands, Norway and the United States were presented with eight hypothetical vignettes of incompetent critically ill patients of different ages. They were asked to make assessments about best interest, respect for surrogate autonomy and to rank the patients in a triage scenario. In total, 2237 physicians responded (average response rate 61%). In all countries and scenarios, participants did not accept to withhold resuscitation if they estimated it was in the patient's best interest, except for scenarios involving neonates. Young children (other than neonates) were given high priority for resuscitation, regardless of existing disability. For neonates, surrogate autonomy outweighed assessment of best interest. In all countries, a 2-month-old-infant with meningitis and a multiply disabled 7-year old were resuscitated first in the triage scenario, with more variable ranking of the two neonates, which were ranked below patients with considerably worse prognosis. The value placed on the life of newborns is less than that expected according to predicted clinical outcomes and current legal and ethical theory relative to best interests. Value assessments on the basis of age, disability and prognosis appear to transcend culture, politics and religion in this domain.

The usual age at onset of narcolepsy with cataplexy is in the second or third decade. In cases with late onset narcolepsy with cataplexy, symptoms are usually mild with relatively less severe daytime sleepiness and less frequent cataplexy. Here we present a case of narcolepsy with cataplexy with onset of symptoms around sixty years of age. This case is unique, with severe daytime sleepiness both by subjective report as well as on objective Multiple Sleep Latency Test and having multiple cataplexy episodes in a day.

Education and training of undergraduate health science students in public health are insufficient in many parts of the world. This lack is a risk as early interest in specialist training options is a predictor of future training choices. A special interest group (SIG) is one mechanism to engage students, increase awareness and generate interest in public health. The purpose of this case study was to create and study such a group at an African university. An action research study design was used to create and study the SIG. All interested students were invited to participate in the SIG and in the data collection procedures. Data were collected via paper-based and online questionnaires. Records of activities were documented, and a reflective diary was kept by the researcher. Seven SIG meetings were held which were less than planned-some sessions were cancelled due to general student unrest. The composition of the SIG fluctuated, but the core group of 16 students consisted of 12 females (75%) and 4 males (25%). Despite faculty-wide marketing, all the participants were medical students. The most successful marketing strategy was done by two lecturers. A total of 12 participants' motivation (75%) was to learn more about public health. Despite the range of participants being over 4-year groups with varying schedules and commitments, a convenient day and meeting time were identified. The social capital of lecturers was harnessed to invite external guest lecturers as planned field trips proved impractical. At the mid-year point, six students (38%) thought that they would consider public health as a career choice. A decision was made to recruit new members via a seminar, and 37 possible new members were identified in the process. A SIG appears to be an effective strategy to increase public health interest among students. This finding is key in settings with particular health workforce shortages and high burdens of disease.

To study the population-based annual incidence rates of exudative, dry and all cases of symptomatic age-related macular degeneration (AMD) in different age and sex groups. This is a one year, prospective, population-based study on all consecutive new patients with AMD in the hospital district of Central Finland. The diagnosis was confirmed in all patients with slit lamp biomicroscopy, optical coherence tomography (OCT) using a Spectralis HRA + OCT device, and the Heidelberg Eye Explorer 1.6.2.0 program. Fluorescein angiograms were taken when needed. The population-based annual incidence rates of all cases of symptomatic AMD increased from 0.03% (95% CI, 0.01-0.05%) in the age group 50-59 years to 0.82% (95% CI, 0.55-1.09%) in the age group 85-89 years and were 0.2% (95% CI, 0.17-0.24%) in exudative, 0.11% (95% CI, 0.09-0.14%) in dry, and 0.32% (95% CI, 0.28-0.36%) in all cases of AMD in the age group 60 years and older. During the next 20 years in Central Finland the population-based annual incidence rates can be estimated to increase to 0.27% (95% CI, 0.24-0.30%) in exudative, to 0.13% (95% CI, 0.11-0.15%) in dry, and to 0.41% (95% CI, 0.37-0.45%) in all cases of AMD in the age group 60 years and older. The population-based annual incidence of AMD did not show statistically significant differences between males and females (p>0.1). The population-based age-group specific annual incidence rates of symptomatic AMD of this study may help to plan health care provision for patients of AMD.

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

A humble task: restoring virtue in an age of conflicted interests.

PubMed

DuBois, James M; Kraus, Elena M; Mikulec, Anthony A; Cruz-Flores, Salvador; Bakanas, Erin

2013-07-01

Virtues define how we behave when no one else is watching; accordingly, they serve as a bedrock for professional self-regulation, particularly at the level of the individual physician. From the time of William Osler through the end of the 20th century, physician virtue was viewed as an important safeguard for patients and research participants. However, the Institute of Medicine, Association of American Medical Colleges, and other policy groups-relying on social science data indicating that ethical decisions often result from unconscious and biased processes, particularly in the face of financial conflicts of interest-have increasingly rejected physician virtue as an important safeguard for patients.The authors argue that virtue is still needed in medicine-at least as a supplement to regulatory solutions (such as mandatory disclosures). For example, although rarely treated as a reportable conflict of interest, standard fee-for-service medicine can present motives to prioritize self-interest or institutional interests over patient interests. Because conflicts of interest broadly construed are ubiquitous, physician self-regulation (or professional virtue) is still needed. Therefore, the authors explore three strategies that physicians can adopt to minimize the influence of self-serving biases when making medical business ethics decisions. They further argue that humility must serve as a crowning virtue-not a meek humility but, rather, a courageous willingness to recognize one's own limitations and one's need to use "compensating strategies," such as time-outs and consultation with more objective others, when making decisions in the face of conflicting interests.

Ageing and the group-reference effect in memory.

PubMed

Lee, Hyeon-Nyeon; Rosa, Nicole M; Gutchess, Angela H

2016-07-01

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

The potential dynamics of cognitive impairment in schizophrenia is discussed in the literature of the field. Recent publications suggest modest changes in level of cognitive impairment after first psychotic episode. Present article attempts to explore cognitive differences between patients and controls across age groups and differences between age groups in clinical group. One hundred and twenty-eight hospitalized patients with schizophrenia (64 women and 64 men) and 68 individuals from the control group (32 women and 32 men) aged 18-55 years were examined. The patients were divided into age groups (18-25, 26-35, 36-45, 46-55). Both groups were examined using Wisconsin Card Sorting Test, Rey Auditory Verbal Learning Test, Rey Osterrieth Complex Figure Test, Trail Making Test (A and B), Stroop Test, verbal fluency test and Wechsler digit span. Patients with schizophrenia obtained significantly lower scores versus the control group in regard to all the measured cognitive functions (Mann-Whitney U; p < 0.05. Most deficits were present in all age groups, however, statistically important impairment in executive functions (WCST) were present only in "older" groups. Patients with schizophrenia obtained less favourable results than the control group in all age groups. Deficits regarding executive functions do not seem to be at a significant level among the youngest group, whereas they are more noticeable in the group of 46-55-year-olds. Executive functions are significantly lowered in the group aged 36-45 in comparison to the "younger" groups. The level of cognitive functions shows a mild exacerbation in connection with age, whereas cognitive rigidity proved to be related to the number of years spent without hospital treatment.

To investigate relationships among youth risk behaviors and demographic factors using an adolescent age group approach. Cross-sectional data from a randomly selected population. Risk behaviors were compared within specific demographic factors and by adolescent age groups. Racially diverse, inner-city neighborhoods in two midwestern cities. Teenagers (n = 1350) and parents (n = 1350) of the teenagers. Truancy; arrested/picked up by police; weapon carrying; fighting; sexual intercourse; tobacco, alcohol, and other drug use; demographic factors; and family structure. Youth mean age was 15.4 (+/- 1.7) years and 52% were female; racial/ethnic characteristics were 47% White, 22% Black, 19% Hispanic, and 10% Native American. Parents' mean age was 42.2 (+/- 8.4) years and 81% were female. chi 2 analyses indicated numerous significant (p < .05) youth risk behavior differences within the demographic factors and that many of the differences varied by adolescent age group. For example, risk behavior differences within racial/ethnic groups were most profound in the middle and older age groups, whereas risk behavior differences within parent income, education levels, and family structure were most apparent in the younger age groups. Of the demographic factors, family structure was most frequently associated with the risk behaviors. The results generally suggest that the relationships among risk behaviors and demographic factors vary within the adolescent age groups included in this study. The results will be useful for developing age-appropriate prevention programs for youth who fit the profile for these risk behaviors. The study protocol also includes specific sampling methods that may be useful for future studies that intend to collect data from difficult-to-reach populations.

Dilated cardiomyopathy (DCM) in Doberman Pinschers is an autosomal dominant inherited disease. The prevalence of DCM in Doberman Pinschers of various age groups in Europe is currently unknown, but this information would be important to develop recommendations for screening programs. To evaluate the prevalence of cardiomyopathy in various age groups of Dobermans. Seven hundred and seventy-five examinations in 412 Doberman Pinschers. Dogs were included in a prospective longitudinal cohort study. Each examination included echocardiography and 24-hour ECG (Holter) examination. A cut-off value of >100 ventricular premature contractions (VPCs) per 24 hours on Holter examination or abnormal echocardiography was considered diagnostic for cardiomyopathy. The cumulative prevalence included all dogs with DCM and healthy dogs >7 years of age. DCM prevalence in various age groups was as follows: age group 1 (1 to <2 years) 3.3%, age group 2 (2 to <4 years) 9.9%, age group 3 (4 to <6 years) 12.5%, age group 4 (6 to <8 years) 43.6%, and age group 5 (>8 years) 44.1%. The cumulative prevalence of Doberman Pinscher cardiomyopathy was 58.2%. There was an equal sex distribution, but male dogs showed earlier echocardiographic changes than did female dogs, which had significantly more VPCs. The prevalence of Doberman cardiomyopathy is very high in Europe. Disease manifestation and progression are different between male and female dogs. Yearly screening for DCM by Holter examination and echocardiography is recommended, starting at 2 years of age.

In 2012, focus groups were organized with individuals owning 20+ acres in the Lake States region of the United States (Michigan, Minnesota, and Wisconsin) to discuss various issues related to forest carbon offsetting. Focus group participants consisted of landowners who had responded to an earlier mail-back survey (2010) on forest carbon offsets. Two focus groups were held per state with an average of eight participants each (49 total). While landowner participant types varied, overall convergence was reached on several key issues. In general, discussion results found that the current payment amounts offered for carbon credits are not likely, on their own, to encourage participation in carbon markets. Landowners are most interested in other benefits they can attain through carbon management (e.g., improved stand species mix, wildlife, and trails). Interestingly, landowner perceptions about the condition of their own forest land were most indicative of prospective interest in carbon management. Landowners who felt that their forest was currently in poor condition, or did not meet their forest ownership objectives, were most interested in participating. While the initial survey sought landowner opinions about carbon markets, a majority of focus group participants expressed interest in general carbon management as a means to achieve reduced property taxes.

While the initial survey sought landowner opinions about carbon markets, a majority of focus group participants expressed interest in general carbon management as a means to achieve reduced property taxes.

Demographic change leads to shifting demands in patient care, not only due to older and sicker patients, but also due to ageing and potentially strained nursing staff. High job strain is known to be associated with an intention to leave the job. At the same time prevalence of mental distress is already high. The aim of our work was to develop a small group intervention to prevent mental strain and to enhance healthy ageing at work. © Georg Thieme Verlag KG Stuttgart · New York.

Human identification is one of the most challenging subjects that human has been confronted with. Through the ages, odontological examinations have been a critical determinant in the search of human identity. Data in the form of age, gender, and blood group might provide vital clues in such investigations. In the recent times, it has been often desirable to preserve tissues for further investigations following the unfolding of certain events or discovery of new data. Hence, it is important to gather as much data as possible using less tissue. The purpose of this study was to determine age, sex, and ABO blood group of individual from a single tooth, to determine the effect of different environmental conditions, and to extract maximum information also at the same time preserving some tissue for the further investigation whenever needed. The study sample consisted of sixty teeth divided into four groups under different environmental conditions and time. The teeth were sectioned longitudinally in the buccolingual plane along the midline. Longitudinal ground sections of each tooth were prepared for age determination from cemental lines. Pulp removed was divided into two halves thereafter sex and blood group was determined. For correlation of age between estimated age and actual age, using cemental lines Pearson's correlation coefficient was applied. Further for determination of both sex and blood group between groups, Chi-square test was applied. A strong positive correlation was found between the estimated age and actual age of the study groups. Moreover, there was no significant difference between the actual and determined sex and blood group of the study groups. Although age, sex, and blood group are more reliably determined in freshly extracted teeth, these variables may be of significant help in identification even after a period of 6 weeks postextraction.

The essential tension between leadership and power: when leaders sacrifice group goals for the sake of self-interest.

PubMed

Maner, Jon K; Mead, Nicole L

2010-09-01

Throughout human history, leaders have been responsible for helping groups attain important goals. Ideally, leaders use their power to steer groups toward desired outcomes. However, leaders can also use their power in the service of self-interest rather than effective leadership. Five experiments identified factors within both the person and the social context that determine whether leaders wield their power to promote group goals versus self-interest. In most cases, leaders behaved in a manner consistent with group goals. However, when their power was tenuous due to instability within the hierarchy, leaders high (but not low) in dominance motivation prioritized their own power over group goals: They withheld valuable information from the group, excluded a highly skilled group member, and prevented a proficient group member from having any influence over a group task. These self-interested actions were eliminated when the group was competing against a rival outgroup. Findings provide important insight into factors that influence the way leaders navigate the essential tension between leadership and power.

Purpose To investigate the impact of the Orthopaedic Surgery and Sports Medicine Interest Group (OSSMIG) on medical student interest and confidence in core musculoskeletal (MSK) concepts through supplemental education and experiences at a single tertiary, academic institution. Methods Medical student OSSMIG members at various levels of training were anonymously surveyed at the beginning and end of the 2014–2015 academic year. Results Eighteen (N=18) medical student interest group members completed the survey. Significant improvement in their level of training was observed with regard to respondents’ self-assessed competence and confidence in MSK medicine (p<0.05). Additionally, respondents’ attitudes toward exposure and support from the interest group were significantly higher than those provided by the institution (p<0.05). Members believed OSSMIG increased interest in MSK medicine, improved confidence in their ability to perform orthopedics-related physical exams, strengthened mentorship with residents and attendings, and developed a connection with the Department of Orthopedic Surgery and its residents (median “Strongly Agree”, interquartile range one and two scale items). Conclusion Since its inception 8 years ago, OSSMIG has been well received and has positively impacted University of Washington School of Medicine students through various interventions. Surgical interest groups should target both the students interested in primary care and surgery. Medical schools can provide additional exposure to MSK medicine by leveraging interest groups that provide early clinical experiences and supplementary instruction. PMID:28814909

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

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

Background Only one in five American meets the physical activity recommendations of the Department of Health and Human Services. The proliferation of wearable devices and smartphones for physical activity tracking has led to an increasing number of interventions designed to facilitate regular physical activity, in particular to address the obesity epidemic, but also for cardiovascular disease patients, cancer survivors, and older adults. However, the inconsistent findings pertaining to the accuracy of wearable devices for step counting needs to be addressed, as well as factors known to affect gait (and thus potentially impact accuracy) such as age, body mass index (BMI), or leading arm. Objective We aim to assess the accuracy of recent mobile devices for counting steps, across three different age groups. Methods We recruited 60 participants in three age groups: 18-39 years, 40-64 years, and 65-84 years, who completed two separate 1000 step walks on a treadmill at a self-selected speed between 2 and 3 miles per hour. We tested two smartphones attached on each side of the waist, and five wrist-based devices worn on both wrists (2 devices on one wrist and 3 devices on the other), as well as the Actigraph wGT3X-BT, and swapped sides between each walk. All devices were swapped dominant-to-nondominant side and vice-versa between the two 1000 step walks. The number of steps was recorded with a tally counter. Age, sex, height, weight, and dominant hand were self-reported by each participant. Results Among the 60 participants, 36 were female (60%) and 54 were right-handed (90%). Median age was 53 years (min=19, max=83), median BMI was 24.1 (min=18.4, max=39.6). There was no significant difference in left- and right-hand step counts by device. Our analyses show that the Fitbit Surge significantly undercounted steps across all age groups. Samsung Gear S2 significantly undercounted steps only for participants among the 40-64 year age group. Finally, the Nexus 6P significantly

Attempted or non-fatal self-poisoning in common in Sri Lanka, but little is known about variation of psychiatric morbidity and suicidal intent across differing ages. The aim of this study was to investigate factors associated with non-fatal self-poisoning in Sri Lanka across three different age groups (namely 14-24 years, 25-34 years and ≥ 35 years). It was anticipated that the findings of the study would inform and guide development of preventive interventions for non-fatal self-poisoning in this country. 935 participants were interviewed within one week of admission to hospital for medical management of non-fatal self-poisoning, over a consecutive 14-month period. Socio-demographic factors, types of poison ingested, triggers and psychiatric morbidity was examined as a function of age. Results showed that a majority (83%) of participants were aged below 35 years. Younger participants aged <25 years were significantly more likely to ingest medicinal overdoses, compared to older persons (aged 25-34 years, and ≥ 35 years), who were more likely to ingest pesticides. Recent interpersonal conflict was a proximal trigger seen in all age groups, but suicidal intent, depression and alcohol use disorders increased with age. The overall study findings indicate that most who carry out acts of non-fatal self-poisoning in Sri Lanka are young (aged <35 years). Interpersonal conflict as a trigger is common to all age groups, but psychiatric morbidity and suicidal intent is higher in the older age groups, as is pesticide ingestion. Age specific interventions may be efficacious in the prevention of non-fatal self-poisoning in Sri Lanka. Copyright © 2016 Elsevier B.V. All rights reserved.

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

The main purpose of this study was to report age-based subjective age-of-acquisition (AoA) norms for 600 Turkish words. A total of 115 children, 100 young adults, 115 middle-aged adults, and 127 older adults provided AoA estimates for 600 words on a 7-point scale. The intraclass correlations suggested high reliability, and the AoA estimates were highly correlated across the four age groups. Children gave earlier AoA estimates than the three adult groups; this was true for high-frequency as well as low-frequency words. In addition to the means and standard deviations of the AoA estimates, we report word frequency, concreteness, and imageability ratings, as well as word length measures (numbers of syllables and letters), for the 600 words as supplemental materials. The present ratings represent a potentially useful database for researchers working on lexical processing as well as other aspects of cognitive processing, such as autobiographical memory.

The impact of race/ethnicity upon facial anthropometric data in the US workforce, on the development of personal protective equipment, has not been investigated to any significant degree. The proliferation of minority populations in the US workforce has increased the need to investigate differences in facial dimensions among these workers. The objective of this study was to determine the face shape and size differences among race and age groups from the National Institute for Occupational Safety and Health survey of 3997 US civilian workers. Survey participants were divided into two gender groups, four racial/ethnic groups, and three age groups. Measurements of height, weight, neck circumference, and 18 facial dimensions were collected using traditional anthropometric techniques. A multivariate analysis of the data was performed using Principal Component Analysis. An exploratory analysis to determine the effect of different demographic factors had on anthropometric features was assessed via a linear model. The 21 anthropometric measurements, body mass index, and the first and second principal component scores were dependent variables, while gender, ethnicity, age, occupation, weight, and height served as independent variables. Gender significantly contributes to size for 19 of 24 dependent variables. African-Americans have statistically shorter, wider, and shallower noses than Caucasians. Hispanic workers have 14 facial features that are significantly larger than Caucasians, while their nose protrusion, height, and head length are significantly shorter. The other ethnic group was composed primarily of Asian subjects and has statistically different dimensions from Caucasians for 16 anthropometric values. Nineteen anthropometric values for subjects at least 45 years of age are statistically different from those measured for subjects between 18 and 29 years of age. Workers employed in manufacturing, fire fighting, healthcare, law enforcement, and other occupational

The purpose of this study was to compare both the volumes of the lateral ventricles and the cerebral white matter with gestational age at birth of children with periventricular white matter (PVWM) T2-signal hyperintensities on MR images. The spectrum of neuromotor abnormalities associated with these hyperintensities was also determined. We retrospectively reviewed the MR images of 70 patients who were between the ages of 1 and 5 years and whose images showed PVWM T2-signal hyperintensities. The patients were divided into premature (n = 35 children) and term (n = 35) groups depending on their gestational age at birth. Volumetric analysis was performed on four standardized axial sections using T2-weighted images. Volumes of interest were digitized on the basis of gray-scale densities of signal intensities to define the hemispheric cerebral white matter and lateral ventricles. Age-adjusted comparisons of volumetric measurements between the premature and term groups were performed using analysis of covariance. The volume of the cerebral white matter was smaller in the premature group (54 +/- 2 cm(3)) than in the term group (79 +/- 3 cm(3), p < 0.0001). The volume of the lateral ventricles was greater among the patients in the premature group (30 +/- 2 cm(3)) than among those in the term group (13 +/- 1 cm(3), p < 0.0001). Fifty percent of all the premature children had spastic diplegia or quadriplegia. Thirty-two percent of all the term children had hypotonia. There were patients in both groups whose PVWM T2-signal hyperintensities did not correlate with any neuromotor abnormalities but were associated with seizures or developmental delays. The differences in volumetric measurements of cerebral white matter and lateral ventricles in children with PVWM T2-signal hyperintensities are related to their gestational age at birth. Several neurologic motor abnormalities are found in children with such hyperintensities.

Traditional department-based surgical interest groups in Russian medical schools are useful tools for student-based selection of specialty training. They also form a nucleus for initiating research activities among undergraduate students. In Russia, the Departments of Topographical Anatomy and Operative Surgery play an important role in initiating student-led research and providing learners with advanced, practical surgical skills. In tandem with department-led activities, student surgical interest groups prepare learners through surgical competitions, known as "Surgical Olympiads," which have been conducted in many Russian centers on a regular basis since 1988. Surgical Olympiads stimulate student interest in the development of surgical skills before graduation and encourage students to choose surgery as their postgraduate specialty. Many of the participants in these surgical Olympiads have become highly qualified specialists in general surgery, orthopedic surgery, neurosurgery, urology, gynecology, and emergency medicine. The present article emphasizes the role of student interest groups and surgical Olympiads in clinical anatomical and surgical undergraduate training in Russia. © 2015 American Association of Anatomists.

2015-01-01

In 2008, four doctorate military nurse scientists representing the triservices (Army, Navy, and Air Force) identified a common interest in the health and care of all women in the armed forces. For 7 years, the team's shared vision to improve servicewomen's health inspired them to commit to a rigorous schedule of planning, developing, and implementing an innovative program that has the capability of advancing scientific knowledge and influencing health policy and practice through research. The ultimate goal of the Military Women's Health Research Interest Group (MWHRIG) is to support military clinicians and leaders in making evidence-based practice and policy decisions. They developed a 4-pronged approach to cultivate the science of military women's healthcare: evaluate the existing evidence, develop a research agenda that addresses gaps in knowledge, facilitate the collaboration of multidisciplinary research, and build the bench of future researchers. The MWHRIG has been a resource to key leaders; its value has been validated by multiservice and multidisciplinary consultations. However, the journey to goal attainment has only been achieved by the enduring commitment of these MWHRIG leaders and their passion to ensure the health and wellbeing of the many women who serve in the United States military. This article describes their journey of dedication.

To obtain better insight into the biology of acute myeloid leukemia (AML) in various age groups, this study focused on the genetic changes occurring during a lifetime. This study analyzed the relation between age and genetics from birth to 100 years in 5564 patients with de novo AML diagnosed from 1998 to 2012 (1192 patients from nationwide pediatric studies [AML Berlin-Frankfurt-Münster studies 98 and 2004] and 4372 adults registered with the Munich Leukemia Laboratory). The frequencies of cytogenetic subgroups were age-dependent. Favorable subtypes (t(8;21), inv(16)/t(16;16), and t(15;17)) decreased in general from the pediatric age group (2 to < 18 years; 33%) to the oldest groups (<5% for > 70 years; P < .0001). Unfavorable cytogenetics (-7/del(7), -5/del(5q) or 5p, inv(3)/t(3;3), t(6;9), complex karyotype, 12p, 17p, and 11q23/mixed-lineage leukemia aberrations, excluding t(9;11)) were frequent (42%) in infants (<2 years), had a low frequency in children and young adults (<22%), and increased in frequency up to 36% in patients older than 85 years (P = .01). This was even more significant for complex karyotypes (P ≤ .0001), which also showed a strong increase in the absolute age-specific incidence with age. Interestingly, the frequency of 11q23 abnormalities decreased from infants to older patients. The proportion of clinically relevant molecular aberrations of CCAAT/enhancer binding protein α, nucleophosmin (NPM1), and NPM1/fms-related tyrosine kinase 3-internal tandem duplication increased with age. Altogether, with the exclusion of infants, a significant decrease in the proportion of favorable cytogenetic subtypes and an increase in unfavorable cytogenetics were observed with increasing age. These findings indicate different mechanisms for the pathogenesis of AML; these different mechanisms also suggest directions for etiological research and contribute to the more unfavorable prognosis with increasing age.

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

There is increasing research aimed at addressing whether patients with borderline personality disorder (BPD) may exhibit variations in symptomatology and functioning according to their chronological age. The current study consisted of 169 outpatients diagnosed with BPD, who were divided into four age groups as follows: 16-25 years (n = 41), 26-35 years (n = 43), 36-45 years (n = 45), and 46 and more years (n = 40). Age groups were compared for symptomatology, normal personality traits, psychiatric comorbidities, functioning, and treatment-related features. The younger group had significantly higher levels of physical/verbal aggression and suicide attempts relative to the older group. Conversely, the older group had significantly greater severity of somatization, depression, and anxiety symptoms. In addition, the older group showed significantly greater functional impairment overall and across physical/psychological domains, specifically when compared to the younger group. Overall, these findings may suggest that age-related symptoms should be considered when diagnosing BPD. Also, functional impairments should be the target interventions for older BPD patients.

There is little information regarding direct-to-consumer (DTC) personal genetic testing (PGT) in non-White racial minorities. Using a web-based survey, we compared the pretest interests and attitudes toward DTC-PGT of racial minority and White DTC-PGT customers of 23andMe and Pathway Genomics using chi-square tests and multinomial regression. Data were available for 1487 participants (1389 White, 44 Black, and 54 Asian). Survey responses were similar across racial groups, although a greater proportion of Blacks compared to Whites reported being "very interested" in genetic information related to traits (91.9 vs. 70.8%, p = 0.009). A greater proportion of Asians compared to Whites reported that a "very important" consideration for pursuing DTC-PGT was limited information about their family health history (58.0 vs. 37.5%, p = 0.002). While a number of significant differences between groups were observed in unadjusted analyses, they did not remain significant after adjustment. This study provides a preliminary view of the interests for purchasing DTC-PGT among customers with racial minority backgrounds.

The relative age effect is a well-researched phenomenon, however there is still a dearth of understanding in track and field and female sport. This study investigated the role of relative age on selection for international competition of Spanish age group athletes between 2006–2014. Six hundred and forty two athletes competed for Spain at U20 or U18 age group international competition (n = 359 males; 283 females) across 9 years. The birthdates of these athletes were compared against the population of registered athletes at that time (14,502 males; 10,096 females). The results highlighted the influential role of relative age on selection to these opportunities. In line with previous research, this effect was mediated by age and gender, with stronger effects for both males and younger athletes (U18). The data best supported the ‘maturation-selection’ hypothesis as a mechanism for RAEs. These results highlight the need to carefully consider the role and need for international competitive opportunities at different age groups. A number of possible context relevant solutions are discussed, including correction adjustments techniques and competition structure within track and field. PMID:29689117

2014-01-01

Background: During fixed orthodontic therapy, adolescents tend to have higher chances of gingivitis and gingival enlargement (GE) compared to adults. A cross sectional study was undertaken to evaluate the above hypothesis, by assessing GE in patients of different age groups receiving fixed orthodontic therapy. Materials & Methods: Patients undergoing orthodontic treatment were selected by simple random sampling from the King Khalid University College of Dentistry out patient’s clinic of preventive dental sciences division to form the study group. Participant’s were divided into three age groups and GE was graded as 0, 1 and 2 as per the classification of the American Academy of Periodontology. Data were analyzed by using IBM SPSS version 16.0 (Statistical Package for Social Services, Chicago, IL, USA) and descriptive statistics were obtained. Differences in proportions were compared using the Chi-square test and the significance level was set at p ≤ 0.05. Results: 62.3% (n=33) were males and 37.7% (n=20) were females. Group 1 had 21 patients (39.7%); Group 2 had 24 patients (45.3%) and Group 3 had 8 patients (15.1%).The highest frequency (48%) of GE was observed among the Group 1 age group (10-19 years). Differences in frequency of GE according to age groups were found to be statistically significant (p=0.046).Differences in GE according to the frequency of practicing oral hygiene measures were statistically significant (p<0.001). Conclusion: Highest frequency of GE was observed among the adolescents. The patients who practiced oral hygiene measures more than three times daily did not have any GE. On the other hand, those who brushed and flossed only once daily had the highest percentage of grade 2 GE. How to cite the article: Eid HA, Assiri HA, Kandyala R, Togoo RA, Turakhia VS.

Fluid intake, especially water, is essential for human life and also necessary for physical and mental function. The present study aimed to assess beverage consumption across age groups. A systematic review was conducted. Original research in English language publications and available studies (or abstracts in English) from 2000 to 2013 was searched for by using the medical subheading (MeSH) terms: ('beverage' OR 'fluid' [Major]) AND ('consumption' [Mesh] OR 'drinking' [Mesh] OR 'intake' [Mesh]) AND ('child' [Mesh] OR 'adolescent' [Mesh] OR 'adult' [Mesh]). Article selection was restricted to those papers covering healthy populations of all age groups in a nationwide sample, or from a representative sample of the population of a city or cities, which examined the trends or patterns of beverage intake and the determinants of beverage intake. Sixty-five studies were identified with respect to beverage consumption across age groups. The papers were screened by thoroughly reading titles or abstracts. Full-text articles were assessed by three investigators. Total beverage intake varied between 0.6 and 3.5 L day(-1) among all age groups (males more than females). Plain water contributed up to 58%, 75% and 80% of the total beverage intake in children, adolescents and adults, respectively. Milk consumption was higher among children; consumption of soft drinks was higher among adolescents; and the consumption of tea, coffee and alcoholic beverages was higher among adults. Plain water is the main water source for all age groups and the consumption of other beverages varies according to age. © 2014 The British Dietetic Association Ltd.

2013-04-01

Sexual interest in children resembles sexual gender orientation in terms of early onset and stability across the life span. Although a genetic component to sexual interest in children seems possible, no research has addressed this question to date. Prior research showing familial transmission of pedophilia remains inconclusive about shared environmental or genetic factors. Studies from the domains of sexual orientation and sexually problematic behavior among children pointed toward genetic components. Adult men's sexual interest in youthfulness-related cues may be genetically influenced. The aim of the present study was to test whether male sexual interest in children and youth under age 16 involves a heritable component. The main outcome measure was responses in a confidential survey concerning sexual interest, fantasies, or activity pertaining to children under the age of 16 years during the previous 12 months. The present study used an extended family design within behavioral genetic modeling to estimate the contributions of genetic and environmental factors in the occurrence of adult men's sexual interest in children and youth under age 16. Participants were male twins and their male siblings from a population-based Finnish cohort sample aged 21-43 years (N = 3,967). The incidence of sexual interest in children under age was 3%. Twin correlations were higher for monozygotic than for dizygotic twins. Behavioral genetic model fitting indicated that a model including genetic effects as well as nonshared environmental influences (including measurement error), but not common environmental influences, fits the data best. The amount of variance attributable to nonadditive genetic influences (heritability) was estimated at 14.6%. The present study provides the first indication that genetic influences may play a role in shaping sexual interest toward children and adolescents among adult men. Compared with the variance attributable to nonshared environmental effects

Since 2007, all Canadian medical schools have had at least one established student-led public health interest group (PHIG). The Association of Faculties of Medicine of Canada (AFMC), the Public Health Task Group, and the Public Health Agency of Canada (PHAC) have supported these PHIGs. The authors describe the activities and structure of PHIGs in Canada from 2007 to 2011, plus the extent to which PHIGs met the objectives set out for them by the AFMC Public Health Task Group. Using a standardized template, the authors analyzed funding applications and reports that PHIG executives submitted to the AFMC from 2007 through 2011. The authors created activity categories and collected simple counts of activities within categories. They then used these data to assess how successfully PHIGs have been able to meet their objectives. Fifty-two funding applications, 50 interim reports, and 48 final reports were available for analysis. All 17 Canadian medical schools had at least one established PHIG between 2007 and 2011, and 9 schools (53%) applied for PHIG funding in all four years. Academic activities such as lectures, seminars, and workshops were the most common activities conducted by PHIGs, followed by career exploration and networking. This study found that the AFMC, with funding support from PHAC, was instrumental in initiating PHIGs in 82% (n = 14) of Canadian medical schools. With consistent funding, national networking opportunities, and a common operating structure, PHIGs have been able to accomplish AFMC's objectives for increasing public health awareness amongst medical students.

Age-Group Differences in Interference from Young and Older Emotional Faces.

Ebner, Natalie C; Johnson, Marcia K

2010-11-01

Human attention is selective, focusing on some aspects of events at the expense of others. In particular, angry faces engage attention. Most studies have used pictures of young faces, even when comparing young and older age groups. Two experiments asked (1) whether task-irrelevant faces of young and older individuals with happy, angry, and neutral expressions disrupt performance on a face-unrelated task, (2) whether interference varies for faces of different ages and different facial expressions, and (3) whether young and older adults differ in this regard. Participants gave speeded responses on a number task while irrelevant faces appeared in the background. Both age groups were more distracted by own than other-age faces. In addition, young participants' responses were slower for angry than happy faces, whereas older participants' responses were slower for happy than angry faces. Factors underlying age-group differences in interference from emotional faces of different ages are discussed.

The objective of the study was to determine whether reproductive-age women are more likely to perceive their vulva as abnormal compared with older-aged women. Women aged 18-44 years (group 1) and 45-72 years (group 2) completed a survey on demographics, grooming patterns, vulvar perceptions, and source of information about the vulva. There was no difference between group 1 and group 2 in how often women looked at their vulva or their perception of having a normal vulva (91% vs 93%, P = .76). Both groups were satisfied with the appearance of their vulva (81% vs 82%, P = .71). A higher percentage in group 2 would consider cosmetic surgery if cost were not an issue versus group 1 (15% vs 8%, P = .05). A woman's age does not have an impact on her perception of a normal vulva. The majority of women perceived their vulva to be normal and were satisfied with its appearance. However, older women are more interested in cosmetic vulvar surgery. Copyright © 2012 Mosby, Inc. All rights reserved.

Streptococcus pyogenes(group A) is a major pathogen capable of causing a wide range of diseases in different age group of people. In this study 100 patients were selected who presented with the complaint of sore throat. All the patients were divided in four age groups. Streptococcus pyogenes colonies were confirmed on the basis of beta-haemolysis, bacitracin sensitivity test, and latex agglutination test for group A. Out of a total of 100 samples, 42 were confirmed as group A streptococcus. From this study, it has been observed that all age groups, with maximum occurrence in 5-15 years age group, were suffering from group A streptococcal pharyngitis. Therefore every case of sore throat especially affecting children should be investigated to detect the causative agent for initiation of proper therapy so that the more serious outcome like acute rheumatic fever (ARF) and acute glomerulonephritis (AGN) can be prevented.

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.

The glucose concentrations and times to nadir for newborns of all gestational ages when intrapartum glucose-containing solutions are not routinely provided are unknown. To characterize and compare patterns of initial glucose concentration nadirs by gestational-age groups. A cross-sectional cohort study of 1,366 newborns born in 1998 at the University of Arkansas for Medical Sciences, appropriate for gestational age, nonasphyxiated, nonpolycythemic, and not infants of diabetic mothers, were included. Initial plasma glucose concentrations, before intravenous fluids or feedings, were plotted against time after birth for 4 gestational-age groups (full term [FT], ≥37-42 weeks; late preterm [LPT], ≥34 and < 37 weeks; preterm [PT], ≥28 and < 34 weeks; and extremely low gestational age newborns [ELGAN], 23 and < 28 weeks of gestation). ELGAN had the earliest nadir at 61 ± 4 min, followed by PT newborns (71 ± 2 min), and then LPT and FT newborns at 92-93 min. The time to nadir for ELGAN and PT newborns was significantly earlier than for FT newborns. Glucose nadir concentrations for ELGAN, PT, and LPT newborns were significantly lower than for FT newborns. LPT newborns' pattern of glucose paralleled those of FT newborns, with values approximately 5-6 mg/dL lower during the first 3 h. Plasma glucose nadirs occurred at different times among gestational-age groups during the early postnatal period as follows: ELGAN < PT < LPT ≈ FT. In order to potentially prevent low glucose concentrations at the time of the nadir, exogenous glucose should be provided to all newborns as soon as possible after birth. © 2018 S. Karger AG, Basel.

Age group classification and gender detection based on forced expiratory spirometry.

Cosgun, Sema; Ozbek, I Yucel

2015-08-01

This paper investigates the utility of forced expiratory spirometry (FES) test with efficient machine learning algorithms for the purpose of gender detection and age group classification. The proposed method has three main stages: feature extraction, training of the models and detection. In the first stage, some features are extracted from volume-time curve and expiratory flow-volume loop obtained from FES test. In the second stage, the probabilistic models for each gender and age group are constructed by training Gaussian mixture models (GMMs) and Support vector machine (SVM) algorithm. In the final stage, the gender (or age group) of test subject is estimated by using the trained GMM (or SVM) model. Experiments have been evaluated on a large database from 4571 subjects. The experimental results show that average correct classification rate performance of both GMM and SVM methods based on the FES test is more than 99.3 % and 96.8 % for gender and age group classification, respectively.

We present an age-stratified prospective assessment of urinary and sexual function of 300 patients after robot-assisted laparoscopic prostatectomy (RALP). Subjective assessment data of continence and potency were collected for different age groups (<50, 50-59, and > or =60 years old) preoperatively, and at 1, 3, 6, and 12 months after RALP. Health-related quality of life questionnaires evaluated return of baseline urinary and sexual function at the same time intervals. The three age groups included 21, 129, and 150 patients (aged <50, 50-59, and >60 years old, respectively). Using Kaplan-Meier curves, younger men achieved subjective continence significantly earlier than older age groups when age groups were compared using a 60-year-old cut-off point (P = 0.02). However, subjective continence was noted to be equal among all age groups after 1 year of follow-up. Time to recovery of subjective potency among age groups shows a significant difference in favor of the younger age group (P = 0.01) Objective urinary function is equal between age groups at all time points, while objective sexual function assessment showed a trend toward better results in the younger age group. Younger men will likely have an earlier return of continence and potency compared to older men after RALP. However, continence outcomes were noted to be equal among age groups after I year of follow-up, while younger men continue to report superior potency outcomes compared to older men over the first postoperative year. Such findings are valuable in counseling older men undergoing this procedure.

Managing the conflict between individual needs and group interests--ethical leadership in health care organizations.

PubMed

Shale, Suzanne

2008-03-01

This paper derives from a grounded theory study of how Medical Directors working within the UK National Health Service manage the moral quandaries that they encounter as leaders of health care organizations. The reason health care organizations exist is to provide better care for individuals through providing shared resources for groups of people. This creates a paradox at the heart of health care organization, because serving the interests of groups sometimes runs counter to serving the needs of individuals. The paradox presents ethical dilemmas at every level of the organization, from the boardroom to the bedside. Medical Directors experience these organizational ethical dilemmas most acutely by virtue of their position in the organization. As doctors, their professional ethic obliges them to put the interests of individual patients first. As executive directors, their role is to help secure the delivery of services that meet the needs of the whole patient population. What should they do when the interests of groups of patients, and of individual patients, appear to conflict? The first task of an ethical healthcare organization is to secure the trust of patients, and two examples of medical ethical leadership are discussed against this background. These examples suggest that conflict between individual and population needs is integral to health care organization, so dilemmas addressed at one level of the organization inevitably re-emerge in altered form at other levels. Finally, analysis of the ethical activity that Medical Directors have described affords insight into the interpersonal components of ethical skill and knowledge.

2016-04-01

Research Data Alliance's Interest Group on "Weather, Climate and Air Quality" More than ever in the history of Earth sciences, scientists are confronted with the problem of dealing with huge amounts of data that grow continuously at a rate that becomes a challenge to process and analyse them using conventional methods. Data come from many different and widely distributed sources, ranging from satellite platforms and in-situ sensors to model simulations, and with different degrees of openness. How can Earth scientists deal with this diversity and big volume and extract useful information to understand and predict the relevant processes? The Research Data Alliance (RDA, https://rd-alliance.org/), an organization that promotes and develops new data policies, data standards and focuses on the development of new technical solutions applicable in many distinct areas of sciences, recently entered in its third phase. In this framework, an Interest Group (IG) comprised of community experts that are committed to directly or indirectly enable and facilitate data sharing, exchange, or interoperability in the fields of weather, climate and air quality has been created recently. Its aim is to explore and discuss the challenges for the use and efficient analysis of large and diverse datasets of relevance for these fields taking advantage of the knowledge generated and exchanged in RDA. At the same time, this IG intends to be a meeting point between members of the aforementioned communities to share experiences and propose new solutions to overcome the forthcoming challenges. Based on the collaboration between several research meteorological and European climate institutes, but also taking into account the input from the private (from the renewable energies, satellites and agriculture sectors for example) and public sectors, this IG will suggest practical and applicable solutions for Big Data issues, both at technological and policy level, encountered by these communities.

To assess the efficacy and safety of retrograde intrarenal surgery (RIRS) to treat renal stones in different age groups of patients. We performed a retrospective analysis of 947 patients who underwent RIRS for renal calculi between January 2008 and January 2014. Age at RIRS was analysed both as a continuous and categorical variable and patients were categorized into three age groups; aged ≤ 15 years at surgery (group i, n=51), 16 - 60 years (group Ii, n=726) and>60 years (group iii, n=170). We compared the 3 groups with the regard to stone characteristics, operative parameters and postoperative outcomes. The stone-free rate was 78.4% in group i, 77.5% in group ii, and 81.1% in group iii (P=.587). A multivariate logistic regression analysis showed that only stone size and stone number had significant influence on the stone-free rates after RIRS. Intraoperative complications occurred 13.7% in group i, 5.6% group ii, and 7.6% in group iii. Overall complication rates in children were higher than adult patients but the differences were not statistically significant. We found that only operation time was associated with the increased risk of intraoperative complications. Peroperative medical complications developed in 8 patients (.8%) in group ii and 2 patients (1.1%) in group iii. A 48-year-old man died from septic shock 5 days after the surgery. RIRS was observed to be a safe and effective procedure in all age groups of patients with stone disease, therefore age should not be considered as a limiting factor. Copyright © 2014 AEU.

Five age groups took part in the experimental studies: children of five and seven years, a group of 15-year-old adolescents, a group aged 20-35 years, and a group aged over 60 years; a total of 62 subjects took part. Statistical analysis showed that the latter three groups were not different from each other and were used as an adult control group for comparison with results from children. Five types of search were used: one difficult, in which the target was similar to the distractors, and four easy (for adults but not for children), involving seeking a red or a white element in an empty grid and seeking a target markedly different in shape or color from the distractors. The following measures were analyzed: search time, errors (false alarms and misses), and corrected search times allowing for errors. Children performed significantly worse on all measures: they found all types of search difficult, even the search for a single element. The larger number of false alarms (reactions to nonmeaningful signals) was evidence for a deficiency of inhibitory processes in children, these being controlled by the frontal lobes. The larger number of misses in children may be evidence of weakness of selective attention, which is controlled by the parietal and temporal areas of the cortex. These points may indicate that children have an immature attention system, though this would appear to mature completely by age 15 years.

Mixed-Age Grouping in Early Childhood--Creating the Outdoor Learning Environment

Individual interest, something that persists regardless of the situation, and situational interest, finding personal value in an educational context, have not been studied in medical student education. To determine if individualized case discussions enhance interest in pediatric medicine. During the 2008/2009 academic year, 88 clerkship students participated in clinical case discussions. At orientation, students completed an Interest in Pediatrics (IIP) questionnaire, responding 1 = strongly disagree to 5 = strongly agree. Intervention and control groups were randomly assigned. The intervention group personalized cases to students' medical specialty interests. The control group discussed the case presentation. Groups met twice during the 8-week clerkships, completing a post-IIP at the end of the clerkship. Intervention group interest increased from pre-IIP, mean = 3.64, to post-IIP, mean = 4.22 (z = -2.994, p < 0.05, r = -0.44). On post-IIP, application of pediatric medicine increased for both groups; the intervention group was most significant from pre-IIP, mean = 1.09, to post-IIP, mean = 4.33 (z = -6.038, p < 0.05, r = -0.88). Enhanced interest in pediatrics from the intervention group indicates that creating a learning environment personally relevant to students' careers facilitates interest to learn.

Physical activity may improve chronic pain, anxiety, and depression, which are prevalent among patients in methadone maintenance treatment (MMT), but relatively little is known about the physical activity levels or interest in exercise of patients in MMT. We used a brief self-report instrument to assess physical activity levels, chronic pain, psychiatric distress, and interest in exercise group participation among 303 adults seeking MMT. Most (73%) reported no moderate or vigorous intensity physical activity in the past week; 27% met recommended physical activity levels, and 24% reported interest in exercise group participation. Participants with (compared to those without) chronic pain had higher levels of psychiatric distress and were less likely to meet recommended levels of physical activity (p < .05), but did not differ significantly in their interest in participating in an exercise group. Participants who met recommended levels of physical activity in the past week were more likely to be men and had lower levels of depression than others (p < .05). Low levels of physical activity and low interest in exercise group participation among patients entering MMT point to the need for and likely challenges of implementing exercise interventions in MMT. © American Academy of Addiction Psychiatry.

Lifetime access to fluoridated water (FW) is associated with lower caries experience. However, assessing this association in adults is likely affected by age. Cohort stratification and categorization of per cent lifetime access to fluoridated water (% LAFW) within cohorts are current approaches to this assessment. These approaches require an examination of the % LAFW and caries experience variation within and across age groups and their association to inform future analyses. This secondary analysis aimed to examine the age group variation in % LAFW and caries experience; and the association of % LAFW with caries within and across age groups of adults. A secondary analysis was undertaken using the Australian National Survey of Adult Oral Health 2004-2006 data on 4090 persons aged 15-91 years randomly sampled by a stratified, multistage probability method. Study participants underwent an interview, an oral examination by trained and standardized dentists to determine decayed, missing or filled tooth surfaces (DMFS) and a mailed self-complete questionnaire which collected residential history to calculate % LAFW. Variations in % LAFW and DMFS across age groups (15-34; 35-44; 45-54; 55+) were examined. Multivariable regression log-link models were generated for DMFS score within each age group. The age groups varied in values and distribution of % LAFW. Caries experience was strongly associated with age. % LAFW was significantly associated with DMFS score in the two younger age groups, but not in the others. Multivariable regression models showed that the highest % LAFW quartile had significantly lower DMFS count than the lowest quartile in the two younger age groups (mean ratios: 0.67 and 0.78, respectively), controlling for other covariates. Access to FW was associated with caries experience in Australian adults. The magnitude of associations varied between age groups, dependent on the natural history of caries and its measurement by DMFS. © 2017 John Wiley & Sons A

Objective: To investigate the impact of blood pressure and age on arterial stiffness in general population. Methods: Participants who took part in 2010, 2012 and 2014 Kailuan health examination were included. Data of brachial ankle pulse wave velocity (baPWV) examination were analyzed. According to the WHO criteria of age, participants were divided into 3 age groups: 18-44 years group ( n= 11 608), 45-59 years group ( n= 12 757), above 60 years group ( n= 5 002). Participants were further divided into hypertension group and non-hypertension group according to the diagnostic criteria for hypertension (2010 Chinese guidelines for the managemengt of hypertension). Multiple linear regression analysis was used to analyze the association between systolic blood pressure (SBP) with baPWV in the total participants and then stratified by age groups. Multivariate logistic regression model was used to analyze the influence of blood pressure on arterial stiffness (baPWV≥1 400 cm/s) of various groups. Results: (1)The baseline characteristics of all participants: 35 350 participants completed 2010, 2012 and 2014 Kailuan examinations and took part in baPWV examination. 2 237 participants without blood pressure measurement values were excluded, 1 569 participants with history of peripheral artery disease were excluded, we also excluded 1 016 participants with history of cardiac-cerebral vascular disease. Data from 29 367 participants were analyzed. The age was (48.0±12.4) years old, 21 305 were males (72.5%). (2) Distribution of baPWV in various age groups: baPWV increased with aging. In non-hypertension population, baPWV in 18-44 years group, 45-59 years group, above 60 years group were as follows: 1 299.3, 1 428.7 and 1 704.6 cm/s, respectively. For hypertension participants, the respective values of baPWV were: 1 498.4, 1 640.7 and 1 921.4 cm/s. BaPWV was significantly higher in hypertension group than non-hypertension group of respective age groups ( P< 0.05). (3) Multiple

Ages of the Xinghuadukou Group in the Erguna Block, NE China

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

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

This study aimed to investigate factors affecting frailty by age groups among vulnerable elders in Korea. In this secondary analysis, data were collected from records for 22,868 eldesr registered in the Visiting Health Management program of Publci Health Centers in 2012. Health behaviors, clinically diagnosed disease, frailty, depression and cognitive condition were assessed. Data were analyzed using stepwise regression to determine the associated factors of frailty by age group. Alcohol consumption, physical activity, number of diseases, DM, CVA, arthritis, urinary incontinence, depression and cognitive condition were found to be factors significantly associated with frailty among the elders aged 65~74 (F=135.66, p<.001). Alcohol consumption, physical activity, CVA, arthritis, urinary incontinence, depression and cognitive condition were found to be factors associated with frailty in the elders aged 75~84 (F=245.40, p<.001). Physical activity, CVA, arthritis, depression and cognitive condition were factors associated with frailty in the elders over 85 years of age (F=96.48, p<.001). The findings show that frailty of elders and associated factors were different by age group, and common factors affecting frailty were physical activity, CVA, arthritis, depression and cognitive condition. Thus, these factors should be considered in the development of intervention program for care and prevention of frailty and program should be modified according to age group.

Coupling of Temperament with Mental Illness in Four Age Groups.

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. © The Author(s) 2016.

Price effects on the smoking behaviour of adult age groups.

To provide a cigarette price elasticity reference for adult age groups, and to estimate the smoking behaviour changes in US adults in light of unprecedented state excise tax increases on cigarettes during the 1990s. Individual-level data from the Behavioral Risk Factor Surveillance System for 1993-2000 were merged with state-level cigarette price and tax data. Data were analysed for different age groups using a weighted least squares regression framework. The outcome variables measured were whether an individual was a smoker, whether he/she had tried to quit smoking during the previous year, and how many cigarettes were smoked per day among the total population and among active smokers. This study confirmed previous results that younger individuals are more responsive to price changes than older individuals. Although older age groups are less sensitive to price changes, their smoking behaviour changes are still statistically significant. This study found that while older individuals are less responsive to price changes than younger individuals, their behavioural changes due to cigarette price increases should not be ignored.

Thymic carcinomas are rare epithelial malignancies with limited data to guide management. To identify areas of agreement and variability in current clinical practice, a 16-question electronic survey was given to members of the International Thymic Malignancy Interest Group (ITMIG). Areas of controversy were discussed with the Thymic Carcinoma Working Group and consensus was achieved, as described. A total of 100 ITMIG members responded. There was general agreement regarding the role for multimodality therapy with definitive surgical resection in physically fit patients with advanced but resectable disease. Areas of controversy included the need for histologic confirmation before surgery, the role of adjuvant therapy, the optimal first-line chemotherapy regimen, and the recommended treatment course for marginally resectable disease with invasion into the great vessels, pericardium, and lungs. The results of the questionnaire provide a description of the management of thymic carcinoma by 100 ITMIG members with a specific interest or expertise in thymic malignancies. Although there was agreement in some areas, clinical practice appears to vary significantly. There is a great need for collaborative research to identify optimal evaluation and treatment strategies. Given the need for multimodality therapy in many cases, a multidisciplinary discussion of the management of patients with thymic carcinoma is critical.

Revascularization of damaged limbs/digits is technically feasible, but indications for surgical replantation remain controversial. The authors analyzed the survival rate of upper limb amputations and the associated factors in different age groups. They grouped 371 limb/digit amputees (average age, 44 years; range, 2-85 years) treated in their hospital during the past 10 years into three groups based on age (young, ≤ 15 years, n  = 12; adult, 16-64 years, n  = 302; elderly, ≥ 65 years, n  = 57) and analyzed their injury type (extent of injury and stump status), operation method, presence of medical complications (Charlson comorbidity index), and survival rate. There were 168 replantations, and the overall replantation survival rate was 93%. The Charlson comorbidity index of the replantation patients was 0 in 124 cases; 1 in 32; 2 in 9; and 3 in 3, but it did not show any significant difference in survival rate after replantation. Eight elderly patients (14%) did not opt for replantation. Younger patients tended to undergo replantation, but they had lower success rates due to their severe injury status. The results of this study show that the survival rate of replantation in elderly patients is equal to that in adults. Stump evaluation is important for survival, but the presence of medical complications is not associated with the overall survival rate.

Short-term memory development: differences in serial position curves between age groups and latent classes.

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.

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 survival of children against disaster can be seen from their confidence in their ability (self-efficacy). Self-efficacy can help children to determine their ability against disaster as preparedness. The proper intervention to increase self-efficacy as a protective factor is a therapeutic group therapy. The aim of this research is to measure the increase of self-efficacy of school age children against earthquake and Tsunami through therapeutic group therapy. This research used quasi-experimental design with pre-post-tests with control group. The sample involved in this study is 69 children, where 35 of them are in the experimental group while the rest 34 children are in the control group consisting of school children at the IV and V graders of elementary school. The result of the research showed that the self-efficacy of school children is improved significantly after being treated with therapeutic group therapy (p value < 0,05), those who were not treated with therapeutic group therapy have no significant improvement (p value > 0,05). This research is recommended to be conducted on school age children to improve their self-efficacy against disaster through health education. Copyright © 2018 Elsevier España, S.L.U.

In 1997, the number of newly registered patients with pulmonary tuberculosis increased, compared with that in 1996, in Japan. The majority of the increase were occupied by elder patients 70 years of age or higher. But in younger group less than 30 years old, a reduction in the incidence of tuberculosis had been slowed down, until 1996. The purpose of this report is to elucidate the characteristics of these younger patients. 139 cases younger than 30 years of age, who were hospitalized in the tuberculous ward of IMCJ from April 1995 to March 1998, were investigated, and were compared with the control group (557 cases), 30-79 years old who were hospitalized during the same period. In the younger group, the proportion of women cases, discovered by health examination, foreigners, and contact with TB patients in the past was significantly higher than in the control group. But there were no difference between the both groups, concerning the proportion of those spending irregular life or living alone. The proportion of sputa smear negative cases was significantly higher in the younger group than in the control. For early diagnosis of TB among younger group, the application of bronchofiberscopy and nucleic acid diagnostic method, are encouraged.

Children of psychiatrically ill parents have a high risk themselves to develop a psychiatric illness in adulthood. Prevention aims at strengthening the resilience of these children and reducing psychosocial risk factors. This article found and describes a theoretical concept of prevention groups for children in schoolage (7-16 years) whose parents are psychiatrically ill. First practical experiences are depicted. The Hamburgian model of prevention works with closed and temporary limited groups of children as well as with the parents. It is based on supporting the children's existing coping strategies and the children are encouraged to exchange their individual experiences of the relationships within their families. One conclusion was, that the main thematic emphasis varied considerably depending on the age of the children.

This study examined and compared the incidence patterns of hepatocellular carcinoma among age groups in Taiwan, 30 years after a universal hepatitis B virus immunization program was launched. Data for hepatocellular carcinoma diagnosed in 2003-2011 were collected from the population-based Taiwan Cancer Registry. Age-standardized incidence rates were calculated to analyze and compare the changes in incidence rates and trends. More specific analyses were performed on four age groups separated by sex. A total of 82,856 patients were diagnosed with hepatocellular carcinoma in 2003-2011 in Taiwan, yielding an age-standardized incidence rate of 32.97 per 100,000 person-years. Hepatocellular carcinoma was predominantly diagnosed in middle-aged adults (50.1%) and elderly people (49.1%), in contrast to the low incidences in children (0.04%) and adolescents and young adults (0.8%). Striking variations in trends were found for children (annual percent change: -16.6%, 2003-2010) and adolescents and young adults (annual percent change: -7.9%, 2003-2011). The incidence rate of hepatocellular carcinoma in children decreased to zero in 2011; only a slight decline in trends occurred for the middle-aged group (annual percent change: -2%, 2003-2011), and a slight upward trend was observed for elderly people (1.3%), specifically in women (1.7%). In Taiwan, hepatitis B virus-related hepatocellular carcinoma was nearly eradicated in children in 2011. The findings on age-specific incidence patterns and trends of hepatocellular carcinoma suggest that different control strategies for treating this devastating disease in the future be made according to age.

For more than a decade, primary care residency training programs have struggled to attract graduates of U.S. medical schools. Internal medicine (IM) interest groups (IMIGs) have been widely instituted to foster student interest in careers in IM. Residents can participate in many IMIG activities. Studies have not assessed the benefits gained by resident participants in such groups. A questionnaire was sent to residents at two IM residency training programs that contribute to IMIG activities at one medical school. Both participating and nonparticipating residents were included. The questionnaire was completed by 44 of 58 IM residents (76% response rate; 25 participants and 19 nonparticipants). Free-text advantages reported were teaching (n=6), mentoring (n=8), and leadership (n=5) opportunities, staying current in IM (n=3), encouraging students to enter IM (n=6), and improving resident morale (n=6). Likert-scale responses were higher for participants than for nonparticipants for all questions; nonparticipants also reported that involvement in IMIG activities is beneficial for residents. Statistically significant results were seen for questions regarding the following: improves resident morale, fosters leadership opportunities, is a valuable experience, and feeling qualified to participate. Residents perceive that participation in an IMIG confers significant benefit, providing additional justification for conducting these interest groups.

VisEL: Visualisation of Expertise Level in a Special Interest Group Knowledge Portal

NASA Astrophysics Data System (ADS)

Zulhafizsyam Wan Ahmad, Wan Muhammad; Sulaiman, Shahida; Yusof, Umi Kalsom

A variety of portals are available nowadays to support diverse purposes such as commercial, publishing, personal, affinity and corporate portals. Affinity portals promote electronic communities who share common interest such as a special interest group (SIG). Knowledge portal is an emerging trend that benefits the existing portal technology by designing such portals with proper representation of the members' shared knowledge. Besides textual representation for diverse expertise levels, graphical visualisation will be able to support the requirements in searching and representing expertise level among e-community. There is a number of existing SIG portals available. However, they do not visualise effectively and accurately the expertise level of members and make it difficult for users to search their targeted experts for instance searching the highest expertise level to have a discussion and to solve their problems related to a project. The goal of this paper is to propose a graphical visualisation of expertise level method (VisEL) using an interactive tag cloud technique that represents expertise level of each member based on their knowledge in a software engineering SIG portal.

Annual age-grouping is a common organizational strategy in sport. However, such a strategy appears to promote relative age effects (RAEs). RAEs refer both to the immediate participation and long-term attainment constraints in sport, occurring as a result of chronological age and associated physical (e.g. height) differences as well as selection practices in annual age-grouped cohorts. This article represents the first meta-analytical review of RAEs, aimed to collectively determine (i) the overall prevalence and strength of RAEs across and within sports, and (ii) identify moderator variables. A total of 38 studies, spanning 1984-2007, containing 253 independent samples across 14 sports and 16 countries were re-examined and included in a single analysis using odds ratios and random effects procedures for combining study estimates. Overall results identified consistent prevalence of RAEs, but with small effect sizes. Effect size increased linearly with relative age differences. Follow-up analyses identified age category, skill level and sport context as moderators of RAE magnitude. Sports context involving adolescent (aged 15-18 years) males, at the representative (i.e. regional and national) level in highly popular sports appear most at risk to RAE inequalities. Researchers need to understand the mechanisms by which RAEs magnify and subside, as well as confirm whether RAEs exist in female and more culturally diverse contexts. To reduce and eliminate this social inequality from influencing athletes' experiences, especially within developmental periods, direct policy, organizational and practitioner intervention is required.

These studies explore elementary-school-aged children's ability to evaluate circular explanations and whether they respond to receiving weak explanations by expressing interest in additional learning. In the first study, 6-, 8-, and 10-year-olds (n = 53) heard why questions about unfamiliar animals. For each question, they rated the quality of single explanations and later selected the best explanation between pairs of circular and noncircular explanations. When judging single explanations, 8- and 10-year-olds, and to some extent 6-year-olds, provided higher ratings for noncircular explanations compared to circular ones. When selecting between pairs of explanations, all age groups preferred noncircular explanations to circular ones, but older children did so more consistently than 6-year-olds. Children who recognized the weakness of the single circular explanations were more interested in receiving additional information about the question topics. In Study 2, all three age groups (n = 87) provided higher ratings for noncircular explanations compared to circular ones when listening to responses to how questions, but older children showed a greater distinction in their ratings than 6-year-olds. Moreover, the link between recognizing circular explanations as weak and interest in future learning could not be accounted for solely by individual differences in verbal intelligence. These findings illustrate the developmental trajectory of explanation evaluation and support that recognition of weak explanations is linked to interest in future learning across the elementary years. Implications for education are discussed.

2018-02-01

As the workforce ages, occupational injuries from falls on the same level will increase. Some industries may be more affected than others. We conducted a cross-sectional study using data from the Bureau of Labor Statistics to estimate same-level fall injury incidence rates by age group, gender, and industry for four sectors: 1) healthcare and social assistance; 2) manufacturing; 3) retail; and 4) transportation and warehousing. We calculated rate ratios and rate differences by age group and gender. Same-level fall injury incidence rates increase with age in all four sectors. However, patterns of rate ratios and rate differences vary by age group, gender, and industry. Younger workers, men, and manufacturing workers generally have lower rates. Variation in incidence rates suggests there are unrealized opportunities to prevent same-level fall injuries. Interventions should be evaluated for their effectiveness at reducing injuries, avoiding gender- or age-discrimination and improving work ability. © 2017 Wiley Periodicals, Inc.

The aim of this study was to investigate the association between the T1ρ and T2 values and the progression of cartilage degeneration in patients of the same age group. Sagittal T1ρ and T2 mapping and three-dimensional (3D) gradient-echo images were obtained from 78 subjects with medial knee osteoarthritis (OA). The degree of patella cartilage degeneration was classified into four groups using MRI-based grading: apparently normal cartilage, mild OA, moderate OA, and severe OA group. We measured the T1ρ and T2 values (ms) in the regions of interest set on the full-thickness patella cartilage. Then, we analyzed the relationship between the T1ρ and T2 values and the degree of patella cartilage degeneration. There were no significant differences in age among the four groups. Both the T1ρ and T2 values showed a positive correlation with the degree of OA progression (ρ=0.737 and ρ=0.632, respectively). By comparison between the apparently normal cartilage and the mild OA groups, there were significant differences in the T1ρ mapping, but not in the T2 mapping. Our study confirmed that T1ρ and T2 mapping can quantitatively evaluate the degree of patella cartilage degeneration in patients within the same age group. Copyright © 2014 Elsevier Ireland Ltd.

Objectives: This study was conducted to determine incidence trends of female breast cancer according to age groups and to predict future change in Chiang Mai women through 2028. Method: Data were collected from all hospitals in Chiang Mai in northern Thailand, from 1989 through 2013, and used to investigate effects of age, year of diagnosis (period) and year of birth (cohort) on female breast cancer incidences using an age-period-cohort model. This model features geometric cut trends to predict change by young (<40 years), middle-aged (40-59) and elderly (≥60) age groups. Result: Of 5, 417 female breast cancer patients with a median age of 50 years (interquartile range: 43 to 59 years), 15%, 61% and 24% were young, middle-aged and elderly, respectively. Seventy nine percent of cancer cases in this study were detected at advanced stage. The trend in stage classification showed an increase in percentage of early stage and a decrease in metastatic cancers. Linear trends for cohort and period were not found in young females but were observed in middle-aged and elderly groups. Age-standardized rates (ASR) can be expected to remain stable around 6.8 per 100,000 women-years in young females. In the other age groups, the ASR trends were calculated to increase and reach peaks in 2024 of 120.2 and 138.2 per 100,000 women-years, respectively. Conclusion: Cohort effects or generation-specific effects, such as life style factors and the year of diagnosis (period) might have impacted on increased incidence in women aged over 40 years but not those under 40 years. A budget should be provided for treatment facilities and strategies to detect early stage cancers. The cost effectiveness of screening measures i.e. mammographic screening may need to be reconsidered for women age over 40 years. PMID:28612595

Other age groups than children need to be considered as carriers of Streptococcal pneumoniae serotypes.

PubMed

Slotved, Hans-Christian

2016-10-02

We need to raise the issue that focus on children as the only carriage group for pneumococci is not optimal; we need to consider that other age groups might also be carriers of pneumococcal serotypes causing invasive pneumococcal diseases (IPD) in unvaccinated age groups. The pneumococcal conjugate vaccines (PCV) have successfully removed IPD from vaccinated children. Studies have shown an effect of PCV reducing the pneumococcal carriage of PCV serotypes in children. The status for several countries having used PCV for many years is that they do not see PCV serotypes neither carried nor as a cause of IPD in children. PCV vaccination of children has shown a herd protection effect in unvaccinated groups as a reduction in IPD cases caused by PCV serotypes. However, not all PCV serotypes have disappeared as the cause of IPD in the unvaccinated age groups. The author therefore believes that if we are to see PCV serotypes disappear as a cause of IPD in unvaccinated age groups, we need to perform further carriage studies to examine carriage in other age groups. Alternatively, all age groups should be vaccinated against pneumococci to eliminate IPD caused by PCV serotypes from possible hidden carriers.

This study aims to empirically identify age of onset groups and their clinical and background characteristics in forensic patients with schizophrenia. Hospital charts were reviewed of all 138 forensic patients with schizophrenia admitted to Geha Psychiatric Hospital that serves a catchment area of approximately 500,000 people, from 2000 to 2009 inclusive. Admixture analysis empirically identified early- (M=19.99, SD=3.31) and late-onset groups (M=36.13, SD=9.25). Early-onset was associated with more suicide attempts, violence before the age of 15, and early conduct problems, whereas late-onset was associated with a greater likelihood of violence after the age of 18 and marriage (P<0.01). The current findings provide clinicians with a unique direction for risk assessment and indicate differences in violence between early- and late-onset schizophrenia, particularly co-occurrence of harmful behavioral phenotypes.

To assess the seminal characteristics as well as the sexual behavior of men of various age groups to establish the presence of an aging effect on those characteristics. Semen samples were collected from men (n = 792) undergoing in vitro fertilization or intrauterine insemination in cases of female factor infertility only. Samples were collected using a seminal collection device at intercourse and evaluated manually according to World Health Organization (WHO) standards. Men were divided into four groups according to their ages: (i) 20-30, (ii) 31-40, (iii) 41-50 and (iv) 51-60 years, and their seminal characteristics and responses to a sexual behavior questionnaire were compared. The data showed statistically significant differences in the seminal characteristics tested, most notably in the sperm concentration, motility, grade of motility, hypo-osmotic swelling and normal sperm morphology. Furthermore, the decline in normal sperm morphology with age was more pronounced when using strict criteria rather than WHO standards. There were also differences in total sperm count, total motile sperm and total functional sperm fraction (assessed by both WHO and strict criteria). Significant differences were also observed in the sexual behavior patterns in older men in terms of the number of years they have been trying to conceive, sexual frequency and sexual satisfaction. The data clearly illustrate an aging effect on semen characteristics and sexual behavior in men as they age. It is suggested that the aging effect be taken into consideration when proposing normal standard values for semen characteristics in routine semen analysis as outlined by WHO standards.

Factors like ethnicity, diet and age of an individual have been hypothesized to play a role in determining the makeup of gut microbiome. In order to investigate the gut microbiome structure as well as the inter-microbial associations present therein, we have performed a comprehensive global comparative profiling of the structure (composition, relative heterogeneity and diversity) and the inter-microbial networks in the gut microbiomes of 399 individuals of eight different nationalities. The study identified certain geography-specific trends with respect to composition, intra-group heterogeneity and diversity of the gut microbiomes. Interestingly, the gut microbial association/mutual-exlusion networks were observed to exhibit several cross-geography trends. It was seen that though the composition of gut microbiomes of the American and European individuals were similar, there were distinct patterns in their microbial interaction networks. Amongst European gut-microbiomes, the co-occurrence network obtained for the Danish population was observed to be most dense. Distinct patterns were also observed within Chinese, Japanese and Indian datasets. While performing an age-wise comparison, it was observed that the microbial interactions increased with the age of individuals. Furthermore, certain bacterial groups were identified to be present only in the older age groups. The trends observed in gut microbial networks could be due to the inherent differences in the diet of individuals belonging to different nationalities. For example, the higher number of microbial associations in the Danish population as compared to the Spanish population, may be attributed to the evenly distributed diet of the later. This is in line with previously reported findings which indicate an increase in functional interdependency of microbes in individuals with higher nutritional status. To summarise, the present study identifies geography and age specific patterns in the composition as well as

Hydatid disease is a zoonosis caused by the tapeworm of Echinococcus spp. The disease is widely endemic in many sheep and cattle rearing locales. However, hydatidosis does not remain restricted to endemic geographical locales anymore but rather is a global health concern. It is a major public health burden causing significant morbidity and mortality. Echinococcus granulosus involvement in children has a different pattern than adults. Children of all age groups are susceptible and localization of the disease in the lungs is more commonly seen. Multiple liver cysts in the paediatric age group is relatively uncommon. We report an interesting case of multiple liver cysts in a 5-year old boy which was diagnosed as hydatid cysts on histopathological examination.

Differences in the way local and regional interest groups perceive Sustainable Forest Management in regions with different forest use histories were studied using Southeastern Finland, the Mauricie in Quebec and Central Labrador in Canada as examples of regions with high, medium and low importance of commercial forestry. We present a conceptual model illustrating the cyclic interaction between the forest, cultural models about forests and forest management. We hypothesized that peoples' perceptions would be influenced by their cultural models about forests and would thus vary amongst regions with different forest use histories and among different interest groups. The weightings of the environmental, economic and social components of sustainability as well as themes important for each of the interest groups were elicited using individual listing of SFM indicators and group work aimed at developing a consensus opinion on a common indicator list. In Southeastern Finland the views of the different groups were polarized along the environment-economy axis, whereas in Central Labrador all groups were environmentally oriented. The social dimension was low overall except among the Metis and the Innu in Labrador. Only environmental groups were similar in all three research regions, the largest differences between regions were found among the forestry professionals in their weightings concerning economy and nature. As the importance of commercial forestry increased, a greater importance of economic issues was expressed whereas the opposite trend was observed for issues regarding nature. Also inter-group differences grew as the importance of commercial forestry increased in the region. Forest management and forest use can be seen as factors strongly influencing peoples' cultural models on forests.

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. 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? 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. 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.

Study of pruritus vulvae in geriatric age group in tertiary hospital

PubMed Central

Kaur, Jasleen; Kalsy, Jyotika

2017-01-01

Background: According to the World Health Organization criteria, geriatric population is people above 60 years of age. In this phase of life, a woman has already gone through menopause and its associated emotional, physical, and hormonal changes. These changes are due to gradual loss of estrogen that comes with menopause which results in dramatic changes in the appearance of vulva and vagina. With age, skin of vulva becomes thin, loses elasticity, and moisture so that the patient starts feeling burning and itchy sensation. The normal acidic pH changes to basic which alters the flora and makes the person prone to other bacterial infections. Apart from infections, there are many other dermatological and nondermatological causes of vulvar itching in this age group such as eczema, contact dermatitis, lichen planus (LP), lichen sclerosus atrophicans, lichen simplex chronicus (LSC), prolapse, incontinence, and carcinoma. The aim is to diagnose the causes of pruritus vulvae in the geriatric age group to decrease the misery of these patients. Methods: We selected 40 consecutive females of age group ranging from 60 to 75 years coming to skin OPD with the complaint of pruritus of vulvar region over a period of 1 year. Clinical examination, complete blood count, fasting blood sugar, wet mount, pap smear, and skin biopsy were done in every case. Results: Out of the forty patients who were included in this study, 17 (42.5%) were diagnosed as a case of LSC and 11 (27.5%) patients had atrophic vaginitis. Three (7.5%) patients presented with tinea. Three (7.5%) cases were clinically diagnosed as scabies. Another 2 (5%) cases were diagnosed as LP and Candida was seen in other 2 (5%) cases. 1 (2.5%) case was diagnosed as bacillary vaginosis and 1 (2.5%) patient was of lichen sclerosus. Conclusion: Pruritus vulvae of geriatric age group are of diverse etiology, therefore, treatment based on precise diagnosis is of prime importance. PMID:28442799

Objective: To analyze the resting energy expenditure and optimal energy supply in different age groups of critically ill children on mechanical ventilation in pediatric intensive care unit (PICU). Methods: Patients on mechanical ventilation hospitalized in PICU of Beijing Children's Hospital from March 2015 to March 2016 were enrolled prospectively. Resting energy expenditure of patients was calculated by US Med Graphic company critical care management (CCM) energy metabolism test system after mechanical ventilation. Patients were divided into three groups:<3 years, 3-10 years, and >10 years. The relationship between the measured and predictive resting energy expenditure was analyzed with correlation analysis; while the metabolism status and the optimal energy supply in different age groups were analyzed with chi square test and variance analysis. Results: A total of 102 patients were enrolled, the measured resting energy expenditure all correlated with predictive resting energy expenditure in different age groups (<3 years ( r= 0.3, P= 0.0) ; 3~10 years ( r= 0.6, P= 0.0) ;>10 years ( r= 0.5, P= 0.0) ) . A total of 40 cases in < 3 years group, including: 14 cases of low metabolism (35%), 14 cases of normal metabolism (35%), and 12 cases of high metabolism (30%); 45 cases in 3-10 years group, including: 22 cases of low metabolism (49%), 19 cases of normal metabolism (42%), 4 cases of high metabolism (9%); 17 cases in > 10 years group, including: 12 cases of low metabolism (71%), 4 cases of normal metabolism (23%), 1 case of high metabolism (6%). Metabolism status showed significant differences between different age groups ( χ (2)=11.30, P <0.01, r= -0.01). Infants had higher metabolic status, which lessened with aging. The total average actual energy requirement was (210±84) kJ/ (kg⋅d) . There were significant differences in actual energy requirement between age groups ( F= 46.57, P< 0.001), with (277±77) kJ/ (kg⋅d) in < 3 years group, (184±53) kJ/ (kg�

Health organizations are increasingly using social media, such as Twitter, to disseminate health messages to target audiences. Determining the extent to which the target audience (e.g., age groups) was reached is critical to evaluating the impact of social media education campaigns. The main objective of this study was to examine the separate and joint predictive validity of linguistic and metadata features in predicting the age of Twitter users. We created a labeled dataset of Twitter users across different age groups (youth, young adults, adults) by collecting publicly available birthday announcement tweets using the Twitter Search application programming interface. We manually reviewed results and, for each age-labeled handle, collected the 200 most recent publicly available tweets and user handles' metadata. The labeled data were split into training and test datasets. We created separate models to examine the predictive validity of language features only, metadata features only, language and metadata features, and words/phrases from another age-validated dataset. We estimated accuracy, precision, recall, and F1 metrics for each model. An L1-regularized logistic regression model was conducted for each age group, and predicted probabilities between the training and test sets were compared for each age group. Cohen's d effect sizes were calculated to examine the relative importance of significant features. Models containing both Tweet language features and metadata features performed the best (74% precision, 74% recall, 74% F1) while the model containing only Twitter metadata features were least accurate (58% precision, 60% recall, and 57% F1 score). Top predictive features included use of terms such as "school" for youth and "college" for young adults. Overall, it was more challenging to predict older adults accurately. These results suggest that examining linguistic and Twitter metadata features to predict youth and young adult Twitter users may be helpful for

To understand how demographic variables and depression symptoms relate to the prevalence of wellness, resilience, and age perception within a sample of community-dwelling older adults. In all, 200 residents across 12 senior housing sites were surveyed. Research questions included the following: (1) Do group differences exist in wellness, resilience, and age perception based on age, sex, race, education, and depression symptoms? (2) Which profile of variables is most strongly associated with self-rated depression among older adults? Multivariate analyses of variance were used to examine group differences. A discriminant analysis demonstrated which variables comprised the profile of individuals who ascribed to depression symptoms. Younger respondents (i.e., age 55-70) had significantly lower levels of wellness (η 2 = .034) and resilience (η 2 = .052). Respondents suffering from depression symptoms had lower levels of wellness (η 2 = .155), resilience (η 2 = .163), and positive age perception (η 2 = .067) and higher rates of negative age perception (η 2 = .052). The discriminant analysis correctly categorized 75.3% of the cases related to depression symptoms, and resilience and certain forms of wellness were most relevant. The current study sheds light into within-group differences in wellness, resilience, and age perception that depend on variables such as age and depression.

To evaluate and compare the normative and subjective need for orthodontic treatment within different age groups in Turkey. One thousand and sixteen patients from seven different demographic regions of Turkey (Marmara, Black Sea, East Anatolia, Southeastern Anatolia, Mediterranean, Aegean, and Central Anatolia Region) (mean age ± SD: 12.80 ± 3.57 years) were randomly selected and divided into six age groups (7-8,9-10,11-12,13-14,15-16, and 17-18 year-olds) and categorized according to the dental health component (DHC) of the index for orthodontic treatment need (IOTN). Additionally, the patients were asked to indicate the photograph that was most similar to their own dentition from the 10-point scale of the aesthetic component of IOTN. The DHC of IOTN was not significantly different between the six age groups (P > 0.05). However, no/slight need (aesthetic component 1-4) for orthodontic treatment according to AC of IOTN was significantly higher in 13-14,15-16, and 17-18 age groups than 7-8, 9-10, and 11-12 age groups (P < 0.05). No sex differences were found in both DHC and aesthetic component of IOTN between age groups (P > 0.05). The normative need distribution was homogeneous within all the age groups according to DHC. However, the subjective need for orthodontic treatment was higher in the younger age groups.

An artifacts removal post-processing for epiphyseal region-of-interest (EROI) localization in automated bone age assessment (BAA)

PubMed Central

2011-01-01

Background Segmentation is the most crucial part in the computer-aided bone age assessment. A well-known type of segmentation performed in the system is adaptive segmentation. While providing better result than global thresholding method, the adaptive segmentation produces a lot of unwanted noise that could affect the latter process of epiphysis extraction. Methods A proposed method with anisotropic diffusion as pre-processing and a novel Bounded Area Elimination (BAE) post-processing algorithm to improve the algorithm of ossification site localization technique are designed with the intent of improving the adaptive segmentation result and the region-of interest (ROI) localization accuracy. Results The results are then evaluated by quantitative analysis and qualitative analysis using texture feature evaluation. The result indicates that the image homogeneity after anisotropic diffusion has improved averagely on each age group for 17.59%. Results of experiments showed that the smoothness has been improved averagely 35% after BAE algorithm and the improvement of ROI localization has improved for averagely 8.19%. The MSSIM has improved averagely 10.49% after performing the BAE algorithm on the adaptive segmented hand radiograph. Conclusions The result indicated that hand radiographs which have undergone anisotropic diffusion have greatly reduced the noise in the segmented image and the result as well indicated that the BAE algorithm proposed is capable of removing the artifacts generated in adaptive segmentation.

Background Emerging evidence indicates mobile technology–based strategies may improve access to secondary prevention and reduce risk factors in cardiac patients. However, little is known about cardiac patients’ use of mobile technology, particularly for health reasons and whether the usage varies across patient demographics. Objective This study aimed to describe cardiac patients’ use of mobile technology and to determine variations between age groups after adjusting for education, employment, and confidence with using mobile technology. Methods Cardiac patients eligible for attending cardiac rehabilitation were recruited from 9 hospital and community sites across metropolitan and rural settings in New South Wales, Australia. Participants completed a survey on the use of mobile technology devices, features used, confidence with using mobile technology, willingness and interest in learning, and health-related use. Results The sample (N=282) had a mean age of 66.5 (standard deviation [SD] 10.6) years, 71.9% (203/282) were male, and 79.0% (223/282) lived in a metropolitan area. The most common diagnoses were percutaneous coronary intervention (33.3%, 94/282) and myocardial infarction (22.7%, 64/282). The majority (91.1%, 257/282) used at least one type of technology device, 70.9% (200/282) used mobile technology (mobile phone/tablet), and 31.9% (90/282) used all types. Technology was used by 54.6% (154/282) for health purposes, most often to access information on health conditions (41.4%, 117/282) and medications (34.8%, 98/282). Age had an important independent association with the use of mobile technology after adjusting for education, employment, and confidence. The youngest group (<56 years) was over 4 times more likely to use any mobile technology than the oldest (>69 years) age group (odds ratio [OR] 4.45, 95% CI 1.46-13.55), 5 times more likely to use mobile apps (OR 5.00, 95% CI 2.01-12.44), and 3 times more likely to use technology for health

2014-05-01

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.

Morphometric data of the frontal lobe are important for surgical planning of lesions in the frontal lobe and its surroundings. Magnetic resonance imaging (MRI) techniques provide suitable data for this purpose. In our study, the morphometric data of mid-sagittal MRI of the frontal lobe in certain age and gender groups of children have been presented. In a normal age group of 6-17-year-old participants, the length of the line passing through predetermined different points, including the frontal pole (FP), commissura anterior (AC), commissura posterior (PC), the outermost point of corpus callosum genu (AGCC), the innermost point of corpus callosum genu (IGCC), tuberculum sella (TS), AGCC and IGCC points parallel to AC-PC line and the point such line crosses at the frontal lobe surface (FCS) were measured in three age groups (6-9, 10-13 and 14-17 years) for each gender. The frontal lobe morphometric data were higher in males than females. Frontal lobe measurements peak at the age group of 10-13 in the male and at the age group of 6-13 in the female. In boys, the length of FP-AC increases 4.1% in the 10-13 age group compared with the 6-9-year-old group, while this increase is 2.3% in girls. Differences in age and gender groups were determined. While the length of AGCC-IGCC increases 10.4% in adults, in children aged 6-17, the length of AC-PC is 11.5% greater than adults. These data will contribute to the preliminary assessment for developing a surgical plan in fine interventions in the frontal lobe and its surroundings in children.

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. 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. 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. 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). 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.

Cell population data (CPD) describe physical parameters of white blood cell subpopulations and are reported to be of some value in the diagnosis of sepsis in neonates. Before using the CPD for diagnosing sepsis, the baseline features of the CPD distribution in healthy neonates should be clarified. The aim of this study was to compare the CPD distributions of healthy neonates and other age groups and to identify perinatal factors that are associated with changes in the CPD distribution of healthy neonates. The CPD distribution of 69 samples from term neonates was compared with adolescents and adults. The CPD distribution of 163 samples from healthy neonates was analyzed in association with perinatal factors, including gestational age, chronologic age, birthweight, delivery mode, premature rupture of membranes, diabetes, and pregnancy-induced hypertension. The CPD distribution for term neonates was significantly different from those in adolescents and adults. The mean lymphocyte volume showed a negative correlation with gestational age at birth (r = -0.305; P < 0.01). The mean neutrophil volume was smaller in the cesarean section group than in the normal delivery group. The small for gestational age (SGA) group had smaller mean neutrophil volume and mean monocyte volume than the appropriate for gestational age group. The CPD distribution of healthy neonates differed from those of adolescents or adults, and the differences were associated with gestational age, delivery mode, and being SGA. © 2015 John Wiley & Sons Ltd.

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

Relatively little has been written about the outcomes of medical stabilization, analyzed specifically across the age spectrum, in adults with severe anorexia nervosa (AN). We retrospectively evaluated clinical parameters relevant to acuity of illness and outcomes of early refeeding in 142 adults with severe AN, admitted for definitive inpatient medical stabilization from October 1, 2008 to December 31, 2012. Patients were categorized into three age groups: 17 to 29, 30 to 40, and 41+ years. The study included 142 patients with median age of 28 years old (range 17-65 years). Fifty-four percent (n = 78) were under 30 years old, 23% (n = 32) between 30 and 40 years old, and 23% (n = 32) were over 40 years old. Average admission BMI did not differ among age groups, ranging from 12.7 to 13.2 kg/m(2). Of the admission parameters, only low serum albumin levels (more prevalent in older patients), high international normalized ratio (INR) levels (more prevalent in younger patients), and neutropenia (more prevalent in the <30 age group) varied with age. During hospitalization, rates of bradycardia, hypoglycemia, liver dysfunction, very low %IBW, refeeding hypophosphatemia, refeeding edema, length of stay, and discharge BMI did not differ with age. Age group was associated with rate of weekly weight gain only in patients with AN-binge purge subtype. Results demonstrate medical abnormalities and response to medical stabilization in severely ill AN patients during hospitalization were mostly similar across the age span. This information should allay fears that the effect of age will make medical stabilization more difficult. © 2015 Wiley Periodicals, Inc.

Cigarette smoking by socioeconomic group, sex, and age: effects of price, income, and health publicity.

To assess effects of price, income, and health publicity on cigarette smoking by age, sex, and socioeconomic group. Econometric multiple regression analysis of data on cigarette smoking from the British general household survey. Random sample of adult population in Britain interviewed for biennial general household surveys 1972-90. Changes in cigarette consumption and prevalence of smoking. Price elasticities of demand for cigarettes (percentage change in cigarette consumption for a 1% change in price) were significant at -0.5 (95% confidence interval -0.8 to -0.1) for men and -0.6 (-0.9 to -0.3) for women, were highest in socioeconomic group V (-1.0 for men and -0.9 for women), and lowest (not significantly different from zero) in socioeconomic groups I and II. The gradient in price elasticities by socioeconomic group was significant for men (F = 5.6, P = 0.02) and for women (F = 6.1, P = 0.02). Price was a significant factor in cigarette consumption by age for women in every age group and for men aged 25-34. Cigarette consumption by young men aged 16-34 increased with income. There was a significant decrease in smoking over time by women in socioeconomic groups I and II and by men in all age and social groups except socioeconomic group V attributable to health publicity. Price significantly affected smoking prevalence in socioeconomic group V (-0.6 for men and -0.5 for women) and for all women (-0.2). Men and women in lower socioeconomic groups are more responsive than are those in higher socioeconomic groups to changes in the price of cigarettes and less to health publicity. Women of all ages, including teenagers, appear to have been less responsive to health publicity than have men but more responsive to price. Response to health publicity decreased linearly with age. Real price increases in cigarettes could narrow differences between socioeconomic groups in smoking and the related inequalities in health, but specific measures would be necessary to ameliorate

PubMed Central

Paulsson Do, Ulrica; Edlund, Birgitta; Stenhammar, Christina; Westerling, Ragnar

2014-01-01

Purpose: There is lack of evidence on the effects of health-promoting programmes among adolescents. Health behaviour models and studies seldom compare the underlying factors of unhealthy behaviours between different adolescent age groups. The main objective of this study was to investigate factors including sociodemographic parameters that were associated with vulnerability to health-damaging behaviours and non-adoption of health-enhancing behaviours in different adolescent age groups. Methods: A survey was conducted among 10,590 pupils in the age groups of 13–14, 15–16 and 17–18 years. Structural equation modelling was performed to determine whether health-damaging behaviours (smoking and alcohol consumption) and non-adoption of health-enhancing behaviours (regular meal habits and physical activity) shared an underlying vulnerability. This method was also used to determine whether gender and socio-economic status were associated with an underlying vulnerability to unhealthy behaviours. Results: The findings gave rise to three models, which may reflect the underlying vulnerability to health-damaging behaviours and non-adoption of health-enhancing behaviours at different ages during adolescence. The four behaviours shared what was interpreted as an underlying vulnerability in the 15–16-year-old age group. In the youngest group, all behaviours except for non-participation in physical activity shared an underlying vulnerability. Similarly, alcohol consumption did not form part of the underlying vulnerability in the oldest group. Lower socio-economic status was associated with an underlying vulnerability in all the age groups; female gender was associated with vulnerability in the youngest adolescents and male gender among the oldest adolescents. Conclusions: These results suggest that intervention studies should investigate the benefits of health-promoting programmes designed to prevent health-damaging behaviours and promote health-enhancing behaviours in

Detterbeck, Frank; Korst, Robert

2014-01-01

Thymic malignancies are relatively rare tumors. A general lack of knowledge, misconceptions about benignancy, confusion about the definition of terms, and variability in reporting of outcomes have further hampered progress in these diseases. The International Thymic Malignancy Interest Group has emerged to counter these challenges and has brought together a worldwide multidisciplinary community determined to improve outcomes for these patients. Although the organization is young (initiated in 2010), major early accomplishments have created a foundation and infrastructure for scientific research. These include consensus definitions of terms, an unprecedented global database, development of practical clinical resources and, together with the International Association for the Study of Lung Cancer, development of proposals for the first formal stage classification of these malignant tumors. Many articles have been published or are under way, and a second phase of projects building on the early success is proceeding. The greatest accomplishment of the International Thymic Malignancy Interest Group lies in the establishment of an open culture of collaboration and the engagement of a broad group of individuals united by a common mission. It is a testament to what can be achieved, despite ongoing and inherent challenges, by determination and a collective effort. Copyright © 2014 Elsevier Inc. All rights reserved.

The aim of study was to examine echocardiographic indices of right heart chambers in patients with coronary artery disease in different age groups. On 678 patients aged 38-85 years, who underwent echocardiography, are including with the use of spectral tissue Doppler. Obtained 2 age groups: 1st - patients up to 60 years (n=282) and group 2nd - patients 60 years and older (n=396). In the analysis the obtained results in patients with coronary heart disease in older age groups showed an increase in right ventricular wall thickness, systolic and average pressure in the pulmonary artery. These changes were accompanied by deterioration in left ventricular diastolic function, while the systolic function of the left and right ventricle were independent of age. Thus, the results can be recommended for assessment of right ventricular dysfunction in patients of older age groups.

On June 24, 2017, the 22nd annual Alcohol and Immunology Research Interest Group (AIRIG) meeting was held as a satellite conference during the annual Research Society on Alcoholism (RSA) Scientific Meeting in Denver, Colorado. The 2017 meeting focused broadly on mechanisms that link alcohol to tissue injury and inflammation, and how this research can be translated to improve human health. Two plenary sessions composed the meeting, which first explored the association between alcohol and trauma/tissue injury, and finished with a discussion of alcohol and mucosal inflammation. The presentations encompassed diverse areas of alcohol research, from effects on the brain, to airway and pulmonary systems, to gut barrier disruption. The discussions also thoughtfully highlighted how current laboratory and clinical research can be used to prevent or treat alcohol-related morbidity and mortality. Copyright © 2017 Elsevier Inc.

Morgan-Lopez, Antonio A.; Chew, Robert F.; Ruddle, Paul

2017-01-01

Health organizations are increasingly using social media, such as Twitter, to disseminate health messages to target audiences. Determining the extent to which the target audience (e.g., age groups) was reached is critical to evaluating the impact of social media education campaigns. The main objective of this study was to examine the separate and joint predictive validity of linguistic and metadata features in predicting the age of Twitter users. We created a labeled dataset of Twitter users across different age groups (youth, young adults, adults) by collecting publicly available birthday announcement tweets using the Twitter Search application programming interface. We manually reviewed results and, for each age-labeled handle, collected the 200 most recent publicly available tweets and user handles’ metadata. The labeled data were split into training and test datasets. We created separate models to examine the predictive validity of language features only, metadata features only, language and metadata features, and words/phrases from another age-validated dataset. We estimated accuracy, precision, recall, and F1 metrics for each model. An L1-regularized logistic regression model was conducted for each age group, and predicted probabilities between the training and test sets were compared for each age group. Cohen’s d effect sizes were calculated to examine the relative importance of significant features. Models containing both Tweet language features and metadata features performed the best (74% precision, 74% recall, 74% F1) while the model containing only Twitter metadata features were least accurate (58% precision, 60% recall, and 57% F1 score). Top predictive features included use of terms such as “school” for youth and “college” for young adults. Overall, it was more challenging to predict older adults accurately. These results suggest that examining linguistic and Twitter metadata features to predict youth and young adult Twitter users may be

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.

2016-01-01

This study investigated differences in social-cognitive predictors and self-regulatory planning, as proposed by the health action process approach (HAPA), across three different subjective physical age groups for physical activity. With a cross-sectional design, 521 participants across the chronological age span from 25 to 86 years (M = 48.79; SD = 12.66) were separated into three groups: those who feel physically younger than they are in terms of chronological age, the same perceived and chronological age, and feeling physically older compared to their chronological age. Participants were assessed regarding their perceived vulnerability, outcome expectancies, general intentions, planning, self-efficacy, and stages of physical activity (non-intenders, intenders, and actors). Data were analysed via mean comparison and multigroup structural equation modelling. Mean differences for all but one construct were eminent in all groups, generally showing that those feeling physically younger also report better social-cognitive predictors of physical activity (e.g. lower perceived vulnerability) in comparison to those who feel the same age or older. The model showed that basic working mechanisms of the HAPA can be applied to all groups. With that, the results provide for the first time evidence that principle working mechanism of the HAPA can be applied to all subjective physical age groups. These may be used to tailor health promoting interventions according to participants' needs as a more suitable proxy than chronological age.

The problem of nutrition of schoolchildren as the main index of health status is considered. Recommendations for implementation of correction system of school feeding in conditions of Siberia will be presented. The purpose of work: on the basis of the results of monitoring living activity and assessment of the health of schoolchildren of different age groups in Siberia to develop guidelines on the rational balanced nutrition. Studies bear witness to inadequate diet and regimen of feeding of schoolchildren. In Siberia a progressive deterioration in the health of students during the years of learning is observed, part of diseases is associated with an unbalanced diet. We offer the project, in course of realization of which study in schools are carried out, scientifically grounded recommendations on appropriate diet and regimen of feeding for schoolchildren of different age groups in the Siberia in the cold and warm period of the year are developed. Implementation of recommendations will result in the general improvement of children health and reduction in medical aid appealability due to diseases of the gastrointestinal tract.

Dry eye disease (DED) is a multifactorial ocular surface disease that causes symptoms of ocular pain, discomfort, and decreased visual acuity. It significantly affects quality of life of patients. It is more prevalent in the females and is being specifically in the menopausal and postmenopausal age group. This is believed to be due to the changes in balance of sex hormones. Sex hormones - estrogens and androgens - influence production of all components of the tear film including aqueous layer, lipid, and mucin. Various mechanisms such as decrease in hormonal levels, shift in feedback mechanisms, and changes in receptor receptivity interplay to alter the ocular surface homeostasis and subsequently result in DED. Several studies have suggested potential role of hormone replacement therapy in menopause-associated dry eye symptoms. The purpose of this review is to help the non ophthalmic physicians about DED encountered commonly in menopausal age group. It is important for primary care physicians to understand DED due to its high prevalence, often debilitating symptoms and the potentially preventable and treatable nature of the condition.

The purpose of this study was twofold: (a) to profile physical characteristics and motor abilities of three age groups of soccer players – under 14 years, 14–17, and over 17, playing different positions – goalkeepers, defenders, midfielders, and forwards; and (b) to examine the inter-individual variability among the players in each age group in all physical and physiological measurements performed in the study. In addition, anthropometric, power, strength, and flexibility tests were administered. Findings showed large inter-individual variability in all three age groups and in all playing positions. Differences between playing positions were found only in the 14–17 group (body mass) and in the over-17 group (body height, body mass, fat-free mass, and mean power in the Wingate Anaerobic Test). Due to the observed large inter-individual variability, it was concluded that the findings obtained in the physical and physiological tests should be interpreted with caution when attempting to differentiate between successful and unsuccessful soccer players, as well as when trying to predict future success in soccer.

Wei, Mei-Hue; Dzeng, Annie

2013-06-01

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.

To estimate the dietary lead intakes by different age-sex population groups in China. The lead concentrations of food sample from 3rd Chinese total diet study were determined, and then were combined with the food consumption by population of ten age-sex groups, The lead intakes, and its distribution and dietary sources were obtained. It was found that the mean and median concentrations of lead in all food samples were 0.118 and 0.052mg/kg, respectively. The highest concentration of individual sample and mean concentrations of lead in preserved egg were 8.964mg/kg and 2.577mg/kg, respectively. The vegetable samples in Hubei Province were heavily contaminated. The lead intakes by different age-sex groups were estimated to be 54.9-112.7microg/day. The average dietary lead intakes by 2-7 years old group could reach 86.1% of PTWI, and individual lead intakes by about 30% children in this group exceed PTWI. But the average dietary lead intakes of other age-sex population groups ranged from 42.8% to 86.1% of PTWI. The main sources of dietary lead were cereals and vegetables in ten age-sex population groups, and could reach 72%-80% of total lead intakes. Although the dietary lead intakes by different age-sex population groups are all lower than PTWI, it should be decreased to a lower level. Moreover, the dietary exposures to lead are higher enough for 2-7 years old children and population in some provinces to be considered seriously.

Emerging evidence indicates mobile technology-based strategies may improve access to secondary prevention and reduce risk factors in cardiac patients. However, little is known about cardiac patients' use of mobile technology, particularly for health reasons and whether the usage varies across patient demographics. This study aimed to describe cardiac patients' use of mobile technology and to determine variations between age groups after adjusting for education, employment, and confidence with using mobile technology. Cardiac patients eligible for attending cardiac rehabilitation were recruited from 9 hospital and community sites across metropolitan and rural settings in New South Wales, Australia. Participants completed a survey on the use of mobile technology devices, features used, confidence with using mobile technology, willingness and interest in learning, and health-related use. The sample (N=282) had a mean age of 66.5 (standard deviation [SD] 10.6) years, 71.9% (203/282) were male, and 79.0% (223/282) lived in a metropolitan area. The most common diagnoses were percutaneous coronary intervention (33.3%, 94/282) and myocardial infarction (22.7%, 64/282). The majority (91.1%, 257/282) used at least one type of technology device, 70.9% (200/282) used mobile technology (mobile phone/tablet), and 31.9% (90/282) used all types. Technology was used by 54.6% (154/282) for health purposes, most often to access information on health conditions (41.4%, 117/282) and medications (34.8%, 98/282). Age had an important independent association with the use of mobile technology after adjusting for education, employment, and confidence. The youngest group (<56 years) was over 4 times more likely to use any mobile technology than the oldest (>69 years) age group (odds ratio [OR] 4.45, 95% CI 1.46-13.55), 5 times more likely to use mobile apps (OR 5.00, 95% CI 2.01-12.44), and 3 times more likely to use technology for health-related reasons (OR 3.31, 95% CI 1.34-8.18).

A variety of interventions have been proposed to manage rising demand for Emergency and Urgent Care, described by an NHS England review as unsustainable in the long term. However it is unlikely that any suggested approach will be equally suitable for the diverse population of ED users.We aimed to understand the patterns of demand amongst different types of patients attending ED. We also sought to understand the intended and unintended effects of demand management initiatives. Our study combined insights from routine data, a survey of ED patients, and qualitative interviews with ED staff. This paper describes the results of our analysis of the interviews. We conducted semi-structured interviews with 25 ED and Urgent Care Centre staff across 7 hospital sites in Yorkshire and Humber between 25 April and 11 July 2016. The interview topic guide asked about 4 broad areas; job role, description of patients and their impact on demand, description of inappropriate attendance, and current/future initiatives to deal with rising demand. Interviews were transcribed verbatim and analysed using framework analysis. We analysed the results to identify groups of patients with different patterns of use of ED services. We also explored ED staff experiences of demand management initiatives, and their suggestions for future initiatives. Although we did not ask specifically about patients' age, our analysis revealed that ED staff categorised attenders as children and young people, working age people, and older people. These groups had different reasons for attendance, different routes to the ED, different rate of non-urgent attendance, and different issues driving demand. Staff also described variation in the time taken to treat patients of different ages, with the oldest and youngest patients described as requiring the most time.There was no consensus amongst staff about the effectiveness of initiatives for managing demand. A strikingly wide variety of initiatives were mentioned

Several recent studies have reported that favorable clinical results and a high level of patient satisfaction can generally be obtained with no increased risk of complications after single-bundle anterior cruciate ligament (ACL) reconstruction performed in patients >40 years of age. However, no studies have yet clarified the age-based differences in clinical outcomes after double-bundle reconstruction. To compare clinical outcomes after double-bundle ACL reconstruction using hamstring tendon hybrid grafts between patients in 2 different age groups: ≥40 years and <40 years. Cohort study; Level of evidence, 3. A retrospective study was conducted using 96 patients (48 men, 48 women ; mean age, 37 years) who underwent unilateral ACL reconstruction between 2008 and 2011. These patients were divided into 2 groups: group M included patients ≥40 years of age (n = 40 patients), and group Y included patients <40 years of age (n = 56 patients). All patients underwent the same anatomic double-bundle ACL reconstruction procedure. Clinical outcomes were evaluated at 2 years after surgery. Tunnel enlargement was also evaluated by computed digital radiography at 1 week and 2 years after surgery. Mean postoperative side-to-side differences in anterior laxity were 0.5 ± 1.9 mm and 1.2 ± 1.5 mm in groups M and Y, respectively; there was a significant difference between the 2 groups ( P = .039). There were no significant differences between the groups in Lysholm knee scores, International Knee Documentation Committee (IKDC) scores, or peak muscle torque of the hamstring. On the other hand, peak muscle torque of the quadriceps was significantly lower in group M (81%) than in group Y (89%) ( P = .025). With respect to femoral tunnel enlargement, the posterolateral tunnel in group M was significantly larger than that in group Y on anteroposterior and lateral radiographs ( P = .015 and P = .002, respectively). Equivalent clinical outcomes were seen between the 2 age groups after

Hospital admissions due to pneumonia range from 1.1 to 4 per 1,000 patients and this figure increases with age. Hospitalization causes a decline in functional status. Physical impairment impedes recovery and constitutes a higher risk of disability and mortality in elderly people. The objective of this study is to assess the impact of hospital stay in patients with pneumonia related with age. A total of 116 patients with pneumonia were included in this study, and divided into two age groups:<75 years (n=68) and ≥ 75 years (n=48). Respiratory function, physical function and psychological and emotional profile were evaluated. Pneumonia severity, nutritional status, independence and comorbidities were also assessed. Statistical analyses revealed significant differences between both age groups in pneumonia severity and comorbidities. Significant improvements between admission and discharge were found in lung function in both groups (p<0.05), while a significant decrease (p<0.05) in strength assessed by dynamometer was found in the ≥75 years group. Hospitalization leads to a significant physical impairment in patients admitted for pneumonia. This deterioration increases with age. Copyright © 2014 SEPAR. Published by Elsevier Espana.

Many Americans have inadequate intakes of several nutrients. The Dietary Guidelines for Americans 2015-2020 specifically identified vitamins A, C, D and E, calcium, magnesium, iron, potassium, choline and fiber as "underconsumed nutrients". Based on nationally representative data in 10,698 adults from National Health and Nutrition Examination Surveys (NHANES), 2009-2012, assessments were made of age-group differences in the impact of dietary supplements on nutrient intake and inadequacies. Compared to food alone, use of any dietary supplement plus food was associated with significantly ( p < 0.01) higher intakes of 15-16 of 19 nutrients examined in all age groups; and significantly reduced rates of inadequacy for 10/17, 8/17 and 6/17 nutrients examined among individuals age ≥71, 51-70 and 19-50 years, respectively. Compared to the other age groups, older adults (≥71 years) had lower rates of inadequacy for iron and vitamins A, C, D and E, but higher rates for calcium. An increased prevalence of intakes above the Tolerable Upper Intake Level was seen for 8-9 of 13 nutrients, but were mostly less than 5% of the population. In conclusion, dietary supplement use is associated with increased micronutrient intake, decreased inadequacies, and slight increases in prevalence above the UL, with greater benefits seen among older adults.

Objectives From April 2015, NHS England (NHSE) started to devolve responsibility for commissioning primary care services to clinical commissioning groups (CCGs). The aim of this paper is to explore how CCGs are managing potential conflicts of interest associated with groups of GPs commissioning themselves or their practices to provide services. Design We carried out two telephone surveys using a sample of CCGs. We also used a qualitative case study approach and collected data using interviews and meeting observations in four sites (CCGs). Setting/participants We conducted 57 telephone interviews and 42 face-to-face interviews with general practitioners (GPs) and CCG staff involved in primary care co-commissioning and observed 74 meetings of CCG committees responsible for primary care co-commissioning. Results Conflicts of interest were seen as an inevitable consequence of CCGs commissioning primary care. Particular problems arose with obtaining unbiased clinical input for new incentive schemes and providing support to GP provider federations. Participants in meetings concerning primary care co-commissioning declared conflicts of interest at the outset of meetings. Different approaches were pursued regarding GPs involvement in subsequent discussions and decisions with inconsistency in the exclusion of GPs from meetings. CCG senior management felt confident that the new governance structures and policies dealt adequately with conflicts of interest, but we found these arrangements face limitations. While the revised NHSE statutory guidance on managing conflicts of interest (2016) was seen as an improvement on the original (2014), there still remained some confusion over various terms and concepts contained therein. Conclusions Devolving responsibility for primary care co-commissioning to CCGs created a structural conflict of interest. The NHSE statutory guidance should be refined and clarified so that CCGs can properly manage conflicts of interest. Non

Orienting task effects on EDR and free recall in three age groups.

PubMed

Zelinski, E M; Walsh, D A; Thompson, L W

1978-03-01

The present investigation was designed to examine the effects of orienting task-controlled processing on electrodermal response and free recall at two delay intervals for 94 young, 49 young-old (age 55 to 70), and 61 old-old (age 71 to 85) individuals. Subjects were presented with a list of 25 words and performed one of the following tasks: semantic, nonsemantic, or passive listening, presented in an incidental memory paradigm, or intentional memorization. Recall was obtained 2 min or 48 hours after list presentation. At the 2-min delay, the pattern of recall across tasks for the young-old and old-old subjects was similar to that of college students. Overall, the old-old recalled fewer words than the young and young-old, while the young-old recalled as many words as the young. After 48 hours, the task-related recall pattern was observed only in the young group. The skin conductance data indicated that task effects were similar across the three age groups and that response magnitude was lower in the old-old than the two younger groups. No differences in skin conductance were found between the young and young-old. Age differences in memory processing suggest that difficulties in delayed retrieval of semantically encoded words may increase during late adult years. Differences in electrodermal responses in the old-old compared to the young and young-old suggest that the range of autonomic responsivitiy to task demands may become restricted in advanced age.

To estimate the dietary cadium intakes by different age-sex groups in China. The cadium concentrations of food sample from 3rd Chinese total diet study were determined, and then combine these data with the food consumption by population of ten age-sex groups, The cadium intakes, and its distribution and dietary sources were obtained. It was found that the mean and median concentrations of cadium in all food samples were 0.046 and 0.006 mg/kg, respectively. The cadium contents in shellfish and liver were far higher than other food staffs. The cadium intakes by different age-sex groups were estimated to be 12.0 - 25.9 microg/day, ranged from 30.3% to 67.0% of PTWI. The individual dietary cadium intakes by 14% children in 2 - 7 years old group exceed PTWI. Cereals, vegetables and seafood were the main sources of cadium exposure, and contributed about 80% of total intakes. Although the dietary cadium intakes by different age-sex groups are all lower than PTWI, they are increased in the past decade. Moreover, in some provinces, the cadium burden of people is heavy.

Revisiting measurement invariance in intelligence testing in aging research: Evidence for almost complete metric invariance across age groups.

Sprague, Briana N; Hyun, Jinshil; Molenaar, Peter C M

2017-01-01

Invariance of intelligence across age is often assumed but infrequently explicitly tested. Horn and McArdle (1992) tested measurement invariance of intelligence, providing adequate model fit but might not consider all relevant aspects such as sub-test differences. The goal of the current paper is to explore age-related invariance of the WAIS-R using an alternative model that allows direct tests of age on WAIS-R subtests. Cross-sectional data on 940 participants aged 16-75 from the WAIS-R normative values were used. Subtests examined were information, comprehension, similarities, vocabulary, picture completion, block design, picture arrangement, and object assembly. The two intelligence factors considered were fluid and crystallized intelligence. Self-reported ages were divided into young (16-22, n = 300), adult (29-39, n = 275), middle (40-60, n = 205), and older (61-75, n = 160) adult groups. Results suggested partial metric invariance holds. Although most of the subtests reflected fluid and crystalized intelligence similarly across different ages, invariance did not hold for block design on fluid intelligence and picture arrangement on crystallized intelligence for older adults. Additionally, there was evidence of a correlated residual between information and vocabulary for the young adults only. This partial metric invariance model yielded acceptable model fit compared to previously-proposed invariance models of Horn and McArdle (1992). Almost complete metric invariance holds for a two-factor model of intelligence. Most of the subtests were invariant across age groups, suggesting little evidence for age-related bias in the WAIS-R. However, we did find unique relationships between two subtests and intelligence. Future studies should examine age-related differences in subtests when testing measurement invariance in intelligence.

Background:Interest is assumed to be relevant for students' learning processes. Many studies have investigated students' interest in science; most of them however have not offered differentiated insights into the structure and elements of this interest. Purpose:The aim of this study is to obtain a precise image of secondary school students' interest for school and out-of-school learning opportunities, both formal and informal. The study is part of a larger project on measuring the students' Individual Concept about the Natural Sciences (ICoN), including self-efficacy, beliefs and achievements next to interest variables. Sample:Next to regular school students, a specific cohort will be analyzed as well: participants of science competitions who are regarded as having high interest, and perhaps different interest profiles than regular students. In the study described here, participants of the International Junior Science Olympiad (N = 133) and regular students from secondary schools (N = 305), age cohorts 10 to 17 years, participated. Design and methods:We adapted Holland's well-established RIASEC-framework to analyze if and how it can also be used to assess students' interest within science and in-school and out-of-school (leisure-time and enrichment) activities. The resulting questionnaire was piloted according to quality criteria and applied to analyze profiles of different groups (boys - girls, contest participants - non-participants). Results:The RIASEC-adaption to investigate profiles within science works apparently well for school and leisure-time activities. Concerning the interest in fostering measures, different emphases seem to appear. More research in this field needs to be done to adjust measures better to students' interests and other pre-conditions in the future. Contrasting different groups like gender and participation in a junior science contest uncovered specific interest profiles. Conclusions:The instrument seems to offer a promising approach to

Objective To verify whether differences exist between groups of Brazilian adults aged 40-59 and 60-75 in respective performance on the Bells Test, given the dearth of literature investigating the relationship between focused visual attention and the age factor. Methods Eighty-four neurologically healthy adults (half aged 40-59 and half 60-75) with high educational level (40-59 years group: M=17.75 years' education; SD=4.00; 60-75 years group: M=15.85 years education; SD=3.19) were assessed using the Bells Test. Data on accuracy and processing speed were compared between groups by ANCOVA, controlled for the covariates education and frequency of reading and writing habits. Results There were no significant differences between the age groups. Conclusion It is suggested that aging influences sustained and focused attention and speed processing after 75 years of age on visual cancellation paradigms, when executive and attentional changes tend to be more marked. Further studies should investigate healthy older and oldest-old adults, as well as groups with low and intermediate educational backgrounds. In addition, Brazilian clinical populations should also be characterized, particularly those with neurological disorders that might have visual hemineglect. PMID:29213492

2011-01-01

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 aim of this study was to analyse the impact of different socio-economic variables on the lifestyle factors, like lack of physical activity, diet rich in meat, and smoking, across sex and age groups in the general Austrian population to formulate more targeted public health measures. The Austrian Health Interview Survey 2006-07 contains data of 15,474 people, representative for the general population. Statistical analyses included linear and logistic regression models. Lack of physical activity was more prevalent in women, while unhealthy nutrition and daily smoking were more prevalent in men. Overall, profession was the strongest predictor for health behaviour in men, while the educational level played the most significant role in women. Subjects in higher age groups had a more healthy nutrition and were less likely to smoke, but had a higher chance for lack of physical activity. Socio-economic factors predict lifestyle choices differently in different age groups. For example, in men, the highest percentage of daily smokers was found in the middle age, while the youngest age group was the one that smoked the most in women. Furthermore, the educational level had a reverse effect on women in the oldest age group, where those with tertiary education smoked three times more than those with less education. Our results emphasise the importance of taking a holistic approach towards health, including educational, cultural and age-specific policies to improve the overall health status and health equality of a population.

This study examines US osteopathic residents' and medical students' attitudes and willingness to practice in rural medicine. The multiple aims of this study were to determine: (1) if there are any significant differences in interest in rural medicine among various levels of training; (2) the relative age, gender, and race of those who are intending to pursue a career in rural health; and (3) whether a number of demographic characteristics (age, race, year of study) or participation in a rural elective significantly impacted the students' and residents' interest in practicing in a rural area. In particular, differences between osteopathic students and residents are emphasized, because few previous studies have focused on this topic. De-identified, cross-sectional, descriptive techniques utilizing 2 distinct web-based electronic surveys were used in this study. Each survey was sent electronically to medical students and physicians-in-training. Statistical methods included means, frequencies, and t-tests to determine significant differences among groups. Logistic regression was used to determine the impact of various factors on overall rural interest for each group. A total of 161 students from two osteopathic colleges completed and submitted the survey as well as 51 residents/fellows from a variety of training programs. Approximately 43% of the student respondents and 67% of residents expressed an intention of practicing rural medicine. Several notable differences were found among the opinions of students and residents, particularly regarding the perceived prestige of rural physicians. Among medical students, overall interest in rural practice decreased in years 2 to 4; however, there was a positive influence if the students were aged 34 years or over. As expected, being raised in a rural area had a positive impact on rural interest. Additional findings included the lack of significance for gender or race, and the positive influence of taking a rural elective. For

Women's 'inner-balance': a comparison of stressors, personality traits and health problems by age groups The purposes of this descriptive study were to identify differences in women's stressors, personality mediating traits and symptoms of health problems by age groups, and to guide revisions for development of a shorter, reliable questionnaire to measure women's health and risks for stress-related illnesses. A convenience sample of 299 women aged between 18 and 66 years who resided in the south-western United States and could read English completed a lengthy questionnaire. ANOVAs were used to compare women by three age groups. Young women (18-29 years) reported high stressors, less healthy personality traits, and significantly more physical and emotional symptoms of health problems than middle-age and older women. Middle-age women (30-45 years) had significantly more stressors than other women, but their healthy personality traits may have contributed to fewer health problems. Older women (46-66 years) had the fewest stressors, highest healthy personality traits, and fewest symptoms of problems compared to other age groups. In their roles and relationships as wives, mothers and employees, women experienced multiple stressors such as inadequate physical and emotional support from their spouse/partner, along with parenting and employee difficulties that contributed to their health problems. Young and middle-aged women were more stressed, juggling the multiple responsibilities and demands of their spouse, children, ageing parents, and their occupation, while trying to maintain their own 'inner balance'.

Lineage interests and nonreproductive strategies : An evolutionary approach to medieval religious women.

PubMed

Hill, E

1999-06-01

The nonreproductive role of religious women in the European Middle Ages presents the ideal forum for the discussion of elite family strategies within a historical context. I apply the evolutionary concept of kin selection to this group of women in order to explain how a social formation in which religious women failed to reproduce benefited medieval noble lineages. After a brief review of the roles of noble women in the later Middle Ages, I identify two benefits that nonreproductive women provided within a patrilineal inheritance system. First, spatial segregation and Christian ideology together served to curtail the production of offspring who could pose a threat to lineage interests. Second, cloistered noble women served as a strong political and economic bloc that could further lineage interests within a religious context. Finally, I discuss the evolutionary basis for the formation of groups of nonreproductive women. Using the foundation provided by animal behavioral studies, I apply the twin concepts of cooperative breeding and parental manipulation to noble lineages of the medieval period.

Background Forming one’s identity is thought to be the key developmental task of adolescence, but profound changes in personality traits also occur in this period. The negotiation of complex social settings, the creation of an integrated identity, and career choice are major tasks of adolescence. The adolescent, having to make choices for his or her future, has not only to consider his or her own aspirations and interests but also to possess a capacity for exploration and commitment; in fact, career commitments can be considered as a fit between the study or career that is chosen and personal values, skills, and preferences. Methods The objective of the study reported here was to investigate the role of identity on profile of interests; the relation between identity and decisional style; the correlation between identity, aptitudes, interests, and school performance; and the predictive variables to school success. The research involved 417 Italian students who live in Enna, a small city located in Sicily, Italy, aged 16–19 years (197 males and 220 females) in the fourth year (mean =17.2, standard deviation =0.52) and the fifth year (mean =18.2, standard deviation =0.64) of senior secondary school. The research lasted for one school year; the general group of participants consisted of 470 students, and although all participants agreed to be part of the research, there was a dropout rate of 11.28%. They completed the Ego Identity Process Questionnaire to measure their identity development, the Intelligence Structure Test to investigate aptitudes, the Self-Directed Search to value interests, and General Decision Making Style questionnaire to describe their individual decisional style. Results The data showed that high-school performance was positively associated with rational decision-making style and identity diffusion predicted the use of avoidant style.

Incidence of C-2 fracture is increasing in elderly patients. Patient age also influences decision making in the management of these fractures. There are very limited data on the national trends of incidence, treatment interventions, and resource utilization in patients in different age groups with isolated C-2 fractures. The aim of this study is to investigate the incidence, treatment, complications, length of stay, and hospital charges of isolated C-2 fracture in patients in 3 different age groups by using the Nationwide Inpatient Sample (NIS) database. The data were obtained from NIS from 2002 to 2011. Data on patients with closed fractures of C-2 without spinal cord injury were extracted using ICD-9-CM diagnosis code 805.02. Patients with isolated C-2 fractures were identified by excluding patients with other associated injuries. The cohort was divided into 3 age groups: < 65 years, 65-80 years, and > 80 years. Incidence, treatment characteristics, inpatient/postoperative complications, and hospital charges (mean and total annual charges) were compared between the 3 age groups. A total of 10,336 patients with isolated C-2 fractures were identified. The majority of the patients were in the very elderly age group (> 80 years; 42.3%) followed by 29.7% in the 65- to 80-year age group and 28% in < 65-year age group. From 2002 to 2011, the incidence of hospitalization significantly increased in the 65- to 80-year and > 80-year age groups (p < 0.001). However, the incidence did not change substantially in the < 65-year age group (p = 0.287). Overall, 21% of the patients were treated surgically, and 12.2% of the patients underwent nonoperative interventions (halo and spinal traction). The rate of nonoperative interventions significantly decreased over time in all age groups (p < 0.001). Regardless of treatment given, patients in older age groups had a greater risk of inpatient/postoperative complications, nonroutine discharges, and longer hospitalization. The mean

Little is known about interest in cosmetic surgery among the general public or how this interest is related to gender, age, relationship status, body mass index, or body image satisfaction. The present study tested these associations among a sample of 52,677 heterosexual men and women aged 18 to 65 years who completed the online "ELLE/MSBNC.com Sex and Body Image Survey" in 2003. Many women were interested (48 percent) or possibly interested (23 percent) in cosmetic surgery. A substantial minority of men were also interested (23 percent) or possibly interested (17 percent) in cosmetic surgery. Individuals interested in cosmetic surgery did not report poorer global body image than individuals not interested in cosmetic surgery. Individuals specifically interested in liposuction, however, tended to have poorer body image, and interest in liposuction was greater among heavier individuals. The finding that many women and men are interested in cosmetic surgery has implications for research comparing cosmetic surgery patients to individuals drawn from the general population. Specifically, researchers conducting comparative studies should recognize that many individuals in their control group may be strongly interested in cosmetic surgery, even if they have not yet had any. Furthermore, individuals interested in different types of cosmetic surgery may differ from each other on such attributes as body mass index and body image.

Background It has been found that health-seeking behavior has a certain impact on influenza infection. However, behaviors with/without risk perception on the control of influenza transmission among age groups have not been well quantified. Objectives The purpose of this study was to assess to what extent, under scenarios of with/without control and preventive/protective behaviors, the age-specific network-driven risk perception influences influenza infection. Materials and methods A behavior-influenza model was used to estimate the spread rate of age-specific risk perception in response to an influenza outbreak. A network-based information model was used to assess the effect of network-driven risk perception information transmission on influenza infection. A probabilistic risk model was used to assess the infection risk effect of risk perception with a health behavior change. Results The age-specific overlapping percentage was estimated to be 40%–43%, 55%–60%, and 19%–35% for child, teenage and adult, and elderly age groups, respectively. Individuals perceive the preventive behavior to improve risk perception information transmission among teenage and adult and elderly age groups, but not in the child age group. The population with perceived health behaviors could not effectively decrease the percentage of infection risk in the child age group, whereas for the elderly age group, the percentage of decrease in infection risk was more significant, with a 97.5th percentile estimate of 97%. Conclusion The present integrated behavior-infection model can help health authorities in communicating health messages for an intertwined belief network in which health-seeking behavior plays a key role in controlling influenza infection.

Type 2 diabetes mellitus (T2DM) is the most common form of diabetes. Risk factors for its development include older age, obesity, family history of diabetes, history of gestational diabetes, impaired glucose metabolism, physical inactivity, and race/ethnicity. The purpose of this study was to characterize T2DM burden, from a patient perspective, with respect to age and race/ethnicity. Adults aged ≥18 years with T2DM from a large, Internet-based, nationwide survey were retrospectively analyzed. Demographic and clinical characteristics (glycemic control, body mass index [BMI], comorbidities, and diabetes-related complications), hypoglycemic episodes, and medication adherence were used to assess diabetes burden. Degree of burden was compared across age (18-64, 65-74, and ≥75 years) and racial/ethnic (white, African American, Hispanic, Asian, and American Indian) groups. An apparent association was found between glycemic control and medication adherence. Hispanics had the lowest percentage of participants with a hemoglobin A1c (HbA1c) level <7.0% (24.4%) and the highest percentage of those not knowing their HbA1c levels (55.4%) but also had the poorest medication adherence among racial/ethnic groups. Conversely, American Indians and whites had the best glycemic control, HbA1c knowledge, and medication adherence. The 18- to 64-year age group had the poorest glycemic control (28.8%), the most with unknown HbA1c levels (46.3%), and the poorest medication adherence of the age groups. Mean BMIs were high (>30 mg/kg(2)) for all racial/ethnic groups other than the Asian group (28.9 mg/kg(2)). Approximately 71% of Asians were obese or overweight compared with ≥90% in the other racial/ethnic groups. Mean BMIs decreased with increasing age group (34.5, 32.6, and 29.8 kg/m(2) for the age groups of 18-64, 65-74, and ≥75 years, respectively). Regarding diabetes-related comorbidities, the Asian group had the lowest percentages of those with hypertension (39.1%) and

Osteoarthritis (OA) is one of the most common musculoskeletal disorders, frequently affecting the hands. In the last decade there has been increased awareness concerning this disorder because of its clinical burden. Unfortunately, only limited treatments for symptom alleviation are available, and no effective treatment for disease modification exists. The lack of treatment is due not only to a lack of understanding of the disease process, but also to poor outcome measures to assess the condition. The OMERACT Hand OA Special Interest Group (SIG) has started to develop a core set of outcome measures for hand OA clinical trials, observational studies, and clinical record keeping. At OMERACT 11, results from a Delphi exercise were presented, and a preliminary set of core domains was discussed. The group attempted to adopt the new OMERACT Filter 2.0 in the process, and literature overviews of conventional radiographs, ultrasonography, and magnetic resonance imaging as outcome measures in hand OA were presented. Discussions that followed highlighted further suggestions for core domains, the heterogeneity of hand OA, and future research priorities.

Several nucleic-acid based technologies have recently emerged with capabilities for broad virus detection. One of these, high throughput sequencing, has the potential for novel virus detection because this method does not depend upon prior viral sequence knowledge. However, the use of high throughput sequencing for testing biologicals poses greater challenges as compared to other newly introduced tests due to its technical complexities and big data bioinformatics. Thus, the Advanced Virus Detection Technologies Users Group was formed as a joint effort by regulatory and industry scientists to facilitate discussions and provide a forum for sharing data and experiences using advanced new virus detection technologies, with a focus on high throughput sequencing technologies. The group was initiated as a task force that was coordinated by the Parenteral Drug Association and subsequently became the Advanced Virus Detection Technologies Interest Group to continue efforts for using new technologies for detection of adventitious viruses with broader participation, including international government agencies, academia, and technology service providers. © PDA, Inc. 2016.

Previous research has identified modifiable risk factors for Alzheimer's disease (AD) in older adults. Research is limited on the potential link between these risk factors and subjective memory impairment (SMI), which may precede AD and other dementias. Examination of these potential relationships may help identify those at risk for AD at a stage when interventions may delay or prevent further memory problems. The objective of this study was to determine whether risk factors for AD are associated with SMI among different age groups. Trained interviewers conducted daily telephone surveys (Gallup-Healthways) of a representative community sample of 18,614 U.S. respondents, including 4,425 younger (age 18 to 39 years), 6,365 middle-aged (40 to 59 years), and 7,824 older (60 to 99 years) adults. The surveyors collected data on demographics, lifestyles, and medical information. Less education, smoking, hypertension, diabetes, less exercise, obesity and depression, and interactions among them, were examined for associations with SMI. Weighted logistic regressions and chi-square tests were used to calculate odds ratios and confidence intervals for SMI with each risk factor and pairwise interactions across age groups. Depression, less education, less exercise, and hypertension were significantly associated with SMI in all three age groups. Several interactions between risk factors were significant in younger and middle-aged adults and influenced their associations with SMI. Frequency of SMI increased with age and number of risk factors. Odds of having SMI increased significantly with just having one risk factor. These results indicate that modifiable risk factors for AD are also associated with SMI, suggesting that these relationships occur in a broad range of ages and may be targeted to mitigate further memory problems. Whether modifying these risk factors reduces SMI and the eventual incidence of AD and other dementias later in life remains to be determined.

Cheng, Feon W.; Monnat, Shannon M.; Lohse, Barbara

2015-01-01

BACKGROUND NEEDs for Bones (NFB), based on the Health Belief Model, is a 4-lesson osteoporosis-prevention curriculum for 11-14 year-olds. This study examined the relationship between enjoyment of food tastings and interest in NFB. METHODS NFB was administered by teachers as part of standard practice and evaluated after the 4th lesson using a 21-item survey. Significant clustering of students within classrooms required use of random-intercept multilevel ordinal regression models in SAS proc GLIMMIX, with students nested within classrooms. Analyses considered tasting experience, eating attitudes, sex, grade, and cohort. RESULTS Students (N = 1619; 50% girls) participated from 85 4th-8th grade classrooms (47% 6th grade; 31% 7th grade) in 16 Pennsylvania SNAP-Ed eligible schools over 2 academic years. For all foods tasted, students who did not enjoy the food tasting were less interested in the lesson than students who did enjoy the food tasting (all p < .001); refried beans (OR 0.30), soy milk (OR = 0.55), cranapple juice (OR = 0.51), sunflower kernels (OR = 0.48), and Swiss cheese (OR = 0.49). CONCLUSIONS Enjoyment of food tasting activities can predict interest in nutrition education on osteoporosis prevention, supporting resource allocation and inclusion of food tasting activities in school-age nutrition education.

Controlling prescription drug costs: regulation and the role of interest groups in Medicare and the Veterans Health Administration.

PubMed

Frakt, Austin B; Pizer, Steven D; Hendricks, Ann M

2008-12-01

Medicare and the Veterans Health Administration (VA) both finance large outpatient prescription drug programs, though in very different ways. In the ongoing debate on how to control Medicare spending, some suggest that Medicare should negotiate directly with drug manufacturers, as the VA does. In this article we relate the role of interest groups to policy differences between Medicare and the VA and, in doing so, explain why such a large change to the Medicare drug program is unlikely. We argue that key policy differences are attributable to stable differences in interest group involvement. While this stability makes major changes in Medicare unlikely, it suggests the possibility of leveraging VA drug purchasing to achieve savings in Medicare. This could be done through a VA-administered drug-only benefit for Medicare-enrolled veterans. Such a partnership could incorporate key elements of both programs: capacity to accept large numbers of enrollees (like Medicare) and leverage to negotiate prescription drug prices (like the VA). Moreover, it could be implemented at no cost to the VA while achieving savings for Medicare and beneficiaries.

Shoulder strength value differences between genders and age groups.

PubMed

Balcells-Diaz, Eudald; Daunis-I-Estadella, Pepus

2018-03-01

The strength of a normal shoulder differs according to gender and decreases with age. Therefore, the Constant score, which is a shoulder function measurement tool that allocates 25% of the final score to strength, differs from the absolute values but likely reflects a normal shoulder. To compare group results, a normalized Constant score is needed, and the first step to achieving normalization involves statistically establishing the gender differences and age-related decline. In this investigation, we sought to verify the gender difference and age-related decline in strength. We obtained a randomized representative sample of the general population in a small to medium-sized Spanish city. We then invited this population to participate in our study, and we measured their shoulder strength. We performed a statistical analysis with a power of 80% and a P value < .05. We observed a statistically significant difference between the genders and a statistically significant decline with age. To the best of our knowledge, this is the first investigation to study a representative sample of the general population from which conclusions can be drawn regarding Constant score normalization.

1996-01-01

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.

Although age is thought to correlate with the prognosis of glioma patients, the most appropriate age-group classification standard to evaluate prognosis had not been fully studied. This study aimed to investigate the influence of age-group classification standards on the prognosis of patients with high-grade hemispheric glioma (HGG). This retrospective study of 125 HGG patients used three different classification standards of age-groups (≤ 50 and >50 years old, ≤ 60 and >60 years old, ≤ 45 and 45-65 and ≥ 65 years old) to evaluate the impact of age on prognosis. The primary end-point was overall survival (OS). The Kaplan-Meier method was applied for univariate analysis and Cox proportional hazards model for multivariate analysis. Univariate analysis showed a significant correlation between OS and all three classification standards of age-groups as well as between OS and pathological grade, gender, location of glioma, and regular chemotherapy and radiotherapy treatment. Multivariate analysis showed that the only independent predictors of OS were classification standard of age-groups ≤ 50 and > 50 years old, pathological grade and regular chemotherapy. In summary, the most appropriate classification standard of age-groups as an independent prognostic factor was ≤ 50 and > 50 years old. Pathological grade and chemotherapy were also independent predictors of OS in post-operative HGG patients. Copyright © 2015. Published by Elsevier B.V.

An evaluation of selective feeding by three age-groups of the rainbow mussel Villosa iris

USGS Publications Warehouse

Beck, K.; Neves, R.J.

2003-01-01

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.

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

AIM: To explore the seropositive rate of antibodies against H. pylori (anti-HP) in Taipei City and to compare the relationship of ABO blood groups and H. pylori infection. METHODS: In 1993, high school students in Shih-Lin District were randomly selected for blood samplings by their registration number at school. In addition, similar procedures were performed on the well-children clinics of Taipei Veterans General Hospital. Besides, randomly selected sera from the adults who took the physical examination were recruited for evaluation. Informed consents were obtained from all the subjects before blood samplings and parents were simultaneously informed for those who were younger than 18-year-old. Blood tests for anti-HP and ABO blood groupings were performed by enzyme-linked immunosorbent assay. Chi square tests were used for the comparisons between seroprevalence of H. pylori and ABO blood groups. RESULTS: Totally, 685 subjects were recruited (260 children aged 1-14 years, 425 high school students aged 15-18 years) were evaluated, and another 88 adult healthy volunteers were studied as well for comparison. The age-specific seropositive rate of anti-HP was 1.3% at age 1-5 years, 7.7% at age 6-10 years, and 11.5% at age 11-14 years.

There is growing interest in telehealth-the use of technology to support the remote delivery of health care and promote self-management-as a potential alternative to face-to-face care for patients with chronic diseases. However, little is known about what precipitates interest in the use of telehealth among these patients. This survey forms part of a research program to develop and evaluate a telehealth intervention for patients with two exemplar chronic diseases: depression and raised cardiovascular disease (CVD) risk. The survey was designed to explore the key factors that influence interest in using telehealth in these patient groups. Thirty-four general practices were recruited from two different regions within England. Practice records were searched for patients with (1) depression (aged 18+ years) or (2) 10-year risk of CVD ≥20% and at least one modifiable risk factor (aged 40-74 years). Within each general practice, 54 patients in each chronic disease group were randomly selected to receive a postal questionnaire. Questions assessed five key constructs: sociodemographics, health needs, difficulties accessing health care, technology-related factors (availability, confidence using technology, perceived benefits and drawbacks of telehealth), and satisfaction with prior use of telehealth. Respondents also rated their interest in using different technologies for telehealth (phone, email and Internet, or social media). Relationships between the key constructs and interest in using the three mediums of telehealth were examined using multivariable regression models. Of the 3329 patients who were sent a study questionnaire, 44.40% completed it (872/1740, 50.11% CVD risk; 606/1589, 38.14% depression). Overall, there was moderate interest in using phone-based (854/1423, 60.01%) and email/Internet-based (816/1425, 57.26%) telehealth, but very little interest in social media (243/1430, 16.99%).

2006-12-01

Since its inception in 1995, the University of Washington's Climate Impacts Group (CIG) (funded under NOAA's Regional Integrated Science and Assessments (RISA) Program) has become the leader in exploring the impacts of climate variability and climate change on natural and human systems in the U.S. Pacific Northwest (PNW), specifically climate impacts on water, forest, fish and coastal resource systems. The CIG's research provides PNW planners, decision makers, resource managers, local media, and the general public with valuable knowledge of ways in which the region's key natural resources are vulnerable to changes in climate, and how this vulnerability can be reduced. The CIG engages in climate science in the public interest, conducting original research on the causes and consequences of climate variability and change for the PNW and developing forecasts and decision support tools to support the use of this information in federal, state, local, tribal, and private sector resource management decisions. The CIG's focus on the intersection of climate science and public policy has placed the CIG nationally at the forefront of regional climate impacts assessment and integrated analysis.

Recent studies suggest that circumscribed interests (CI) in females with Autism Spectrum Disorder (ASD) may align more closely with interests reported in typical female development than those typically reported for ASD males. We used eye-tracking to quantify attention to arrays containing combinations of male, female and neutral images in elementary-aged males and females with and without ASD. A number of condition × sex effects emerged, with both groups attending to images that corresponded with interests typically associated with their biological sex. Diagnostic effects reported in similar studies were not replicated in our modified design. Our findings of more typical attention patterns to gender-typical images in ASD females is consistent with evidence of sex differences in CI and inconsistent with the "Extreme Male Brain" theory of ASD.

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

Vocational interests play a central role in the vocational decision-making process and are decisive for the later job satisfaction and vocational success. Based on Ackerman's (1996) notion of trait complexes, specific interest profiles of gifted high-school graduates can be expected. Vocational interests of gifted and highly achieving adolescents were compared to those of their less intelligent/achieving peers according to Holland's (1997) RIASEC model. Further, the impact of intelligence and achievement on interests were analysed while statistically controlling for potentially influencing variables. Changes in interests over time were investigated. N= 4,694 German students (age: M= 19.5, SD= .80; 54.6% females) participated in the study (TOSCA; Köller, Watermann, Trautwein, & Lüdtke, 2004). Interests were assessed in participants' final year at school and again 2 years later (N= 2,318). Gifted participants reported stronger investigative and realistic interests, but lower social interests than less intelligent participants. Highly achieving participants reported higher investigative and (in wave 2) higher artistic interests. Considerable gender differences were found: gifted girls had a flat interest profile, while gifted boys had pronounced realistic and investigative and low social interests. Multilevel multiple regression analyses predicting interests by intelligence and school achievement revealed stable interest profiles. Beyond a strong gender effect, intelligence and school achievement each contributed substantially to the prediction of vocational interests. At the time around graduation from high school, gifted young adults show stable interest profiles, which strongly differ between gender and intelligence groups. These differences are relevant for programmes for the gifted and for vocational counselling. ©2012 The British Psychological Society.

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

The congruence of interests between health care providers and clients is essential if subjects with chronic diseases will be educated. To assess, in patients with rheumatoid arthritis, those fields in which they would like to receive education. Eighty eight patients with rheumatoid arthritis were surveyed about the topics in which they would like to be educated. The inquiry included medical aspects, handicap overcoming, social issues and labor aspects. Eighty two percent of patients were interested in medical aspects, 77% in social issues and 71% in handicap overcoming. Eighty three percent of patients with greater handicaps preferred handicap overcoming, 75% social aspects and 74% medical aspects. Younger patients had a greater interest in labor aspects, those with a recently diagnosed disease were interested in their legal rights and those with a prolonged disease wanted information about self help groups. The greater educational interests of patients with rheumatoid arthritis were on medical aspects. However, those impaired by the disease were interested in handicap overcoming. Age and duration of the disease also influenced the educational interests of patients. Thus, education in these patients must be individualized.

Myofiber type grouping is a histological hallmark of age-related motor unit remodeling. Despite the accepted concept that denervation-reinnervation events lead to myofiber type grouping, the completeness of those conversions remains unknown. Type I myofiber grouping was assessed in vastus lateralis biopsies from Young (26 ± 4 years; n = 27) and Older (66 ± 4 years; n = 91) adults. Grouped and ungrouped type I myofibers were evaluated for phenotypic differences. Higher type I grouping in Older versus Young was driven by more myofibers per group (i.e., larger group size) (P < 0.05). In Older only, grouped type I myofibers displayed larger cross-sectional area, more myonuclei, lower capillary supply, and more sarco(endo)plasmic reticulum calcium ATPase I (SERCA I) expression (P < 0.05) than ungrouped type I myofibers. Grouped type I myofibers retain type II characteristics suggesting that conversion during denervation-reinnervation events is either progressive or incomplete.

Age is integrated in most risk stratification systems for well-differentiated thyroid cancer (WDTC). The most appropriate age threshold for stage grouping of WDTC is debatable. The objective of this study was to evaluate the best age threshold for stage grouping by comparing multivariable models designed to evaluate the independent impact of various prognostic factors, including age based stage grouping, on the disease specific survival (DSS) of our population-based cohort. Data from population-based thyroid cancer cohort of 2125 consecutive WDTC, diagnosed during 1970-2010, with a median follow-up of 11.5 years, was used to calculate DSS using the Kaplan Meier method. Multivariable analysis with Cox proportional hazard model was used to assess independent impact of different prognostic factors on DSS. The Akaike information criterion (AIC), a measure of statistical model fit, was used to identify the most appropriate age threshold model. Delta AIC, Akaike weight, and evidence ratios were calculated to compare the relative strength of different models. The mean age of the patients was 47.3 years. DSS of the cohort was 95.6% and 92.8% at 10 and 20 years respectively. A threshold of 55 years, with the lowest AIC, was identified as the best model. Akaike weight indicated an 85% chance that this age threshold is the best among the compared models, and is 16.8 times more likely to be the best model as compared to a threshold of 45 years. The age threshold of 55 years was found to be the best for TNM stage grouping. Copyright © 2015 Elsevier Ltd. All rights reserved.

Sleep disturbances are common among older people (>65 years). Further, long-term use of sedative hypnoticsin older people is associated with morbidity and mortality. However, older people represent a large span of life years, and few studies have included the oldest-old above 85 years. To investigate and compare sleep quality, use of hypnotics and sleeping habits in different age groups of the older population in the Scania region, Sweden and in relation to sociodemographic- and functional status. A cross-sectional population-based study including 2931 people aged 60-93 years from five different municipalities in Scania was performed during 2001-2004. The sample was divided into age groups, young old (60-72 years), old-old (78-84 years) and oldest-old (87-93) years. Data constitutes of sleep related questions, sociodemographic- and functional status from the study 'Good Ageing in Skane'. Descriptive statistics were used to describe sleep quality, hypnotics use and sleeping habitsin relation to sociodemographic- and functional status. The aim was to investigate associations, not the magnitude of associations between variables. In all age groups, those who used hypnotics and were living alone had significantly poorer sleep quality and shortest sleeping time than nonhypnotic users and those who lived together. A significant increase of hypnotics and frequency of use was seen with increasing age. Frequency of napping increased significantly with degree of dependence in all age groups and with increasing age. Insomnia is still a problem and hypnotic use has not improved sleep for a large number of older people. Hypnotics are effective as short-term treatment, however, nonpharmacological interventions and psychological and behavioural therapies should be considered for treating older people with chronic insomnia.

In order to evaluate a manual-based group program for teachers aiming at strengthening mental health, we examined (1) whether the teachers interested in participating differ from their colleagues without interest and (2) whether there is evidence of subgroups benefiting more than others among those who participated. Out of a basic sample of 949 schoolteachers, 337 teachers declared interest in a group program. All teachers were surveyed with the "General Health Questionnaire", the "Maslach Burnout Inventory" and the "Effort Reward Imbalance Questionnaire". In addition, participating teachers were screened with the "Symptom Checklist 27" T and χ(2)-tests were calculated to detect differences between those interested in the program and the remaining 612 teachers. Six factors were established and used for a regression analysis that identified specific parameters more or less correlating with health benefits of those who participated in the program. Findings showed that those declaring interest in the intervention displayed a higher degree of occupational stress according to all health parameters examined. Teachers interested in the program were significantly younger, more frequently female and single. The regression analysis showed that the baseline scores of the six health parameters were the strongest predictors for improvement. Worse scores before the beginning of the intervention correlated with a more positive effect. Intervention programs aiming at alleviating the mental stress of teachers find the interest of those who need it most. More importantly, the latter are the ones who--at least if our program is applied-benefit best.

Recreational sports are important leisure activities. However, most studies investigating barrier factors and motivation for participation in recreational sports have been limited to specific areas (e.g., a city or school) or demographic groups (e.g., adolescents). Therefore, this study set out to gain a more comprehensive understanding of the behavioral and socioeconomic factors influencing interest in recreational sports participation in Taiwan, as well as to evaluate the effect of any urban-rural divide. This study analyzed data collected by the "Taiwan Social Change Survey" (program five, wave 3) "Leisure Life" questionnaire. We used hierarchical linear modeling to assess respondent interest in recreational sports participation and evaluated the influence of behavioral factors, socioeconomic factors, and residence location (urban/rural). Of the 2,146 participants in this study, 50.3% were male, and the average age was 43.9 years. Location of residence (urban/rural) accounted for 35.3% of the variation in interest in recreational sports participation, while the remaining 64.7% came from the individual level. Participants who lived in rural settings were less interested in recreational sports than their urban counterparts. Gender, educational attainment, participation frequency, health-motivated interest, and appearance-motivated interest were also associated with interest in recreational sports participation. Different communication strategies may be needed to effectively reach different demographic groups. We suggest that future public health campaigns aiming to increase recreational sports participation include tailored interventions and messages to effectively encourage leisure physical activities among all, regardless of demographic boundaries.

Background: Number of deaths increases during periods of elevated heat. Objectives: To examine whether differences in heat-related deaths between 2003 and 2015 occurred in Slovenia. Materials and Methods: We estimated relative risks for deaths for the observed diagnoses, sex, age, and area, as well as 95% confidence intervals and excess deaths associated with heat waves occurring in 2015 and 2003. For comparison between 2015 and 2003, we calculated relative risks ratio and 95% confidence intervals. Results: Statistically significant in 2015 were the following: age group 75+, all causes of deaths (RR = 1.10, 95% CI 1.00–1.22); all population, circulatory system diseases (RR = 1.14, 95% CI 1.01–1.30) and age group 75+, diseases of circulatory system (RR = 1.17, 95% CI 1.01–1.34). Statistically significant in 2003 were the following: female, age group 5–74, circulatory system diseases (RR = 1.69, 95% CI 1.08–2.62). Discussion: Comparison between 2015 and 2003, all, circulatory system diseases (RRR = 1.25, 95% CI 1.01–1.55); male, circulatory system diseases (RRR = 1.85, 95% CI 1.41–2.43); all, age group 75+ circulatory system diseases (RRR = 1.34, 95% CI 1.07–1.69); male, age group 75+, circulatory system diseases (RRR = 1.52, 95% CI 1.03–2.25) and female, age group 75+, circulatory system diseases (RRR = 1.43, 95% CI 1.08–1.89). Conclusions: Public health efforts are urgent and should address circulatory system causes and old age groups. PMID:29361792

Accumulating evidence demonstrates the significant influence of weather factors, especially temperature and humidity, on influenza seasonality. However, it is still unclear whether temperature variation within the same day, that is diurnal temperature range (DTR), is related to influenza seasonality. In addition, the different effects of weather factors on influenza seasonality across age groups have not been well documented in previous studies. Our study aims to explore the effects of DTR and humidity on influenza seasonality, and the differences in the association between weather factors and influenza seasonality among different age groups in Hong Kong, China. Generalized additive models were conducted to flexibly assess the impact of DTR, absolute humidity (vapor pressure, VP), and relative humidity on influenza seasonality in Hong Kong, China, from January 2012 to December 2016. Stratified analyses were performed to determine if the effects of weather factors differ across age groups (< 5, 5-9, 10-64, and > 64 years). The results suggested that DTR, absolute humidity, and relative humidity were significantly related to influenza seasonality in dry period (when VP is less than 20 mb), while no significant association was found in humid period (when VP is greater than 20 mb). The percentage changes of hospitalization rates due to influenza associated with per unit increase of weather factors in the very young children (age 0-4) and the elderly (age 65+) were higher than that in the adults (age 10-64). Diurnal temperature range is significantly associated with influenza seasonality in dry period, and the effects of weather factors differ across age groups in Hong Kong, China.

The purpose of the study was to develop a battery of tests to study social and cognitive impairments for behavioral phenotyping of aging experimental animals with physiological neurodegeneration. Object of the study were outbred CD1 mice in the following groups: 1st group - 12-month old male mice (physiological aging); 2nd group - 2-month old male mice (control group). Social recognition test, elevated plus maze test (EPM), open field test, light-dark box test, and Fear conditioning protocol were used to estimate the neurological status of experimental animals. We found that aging male mice in a contrast to young ones have demonstrated lower social interest to female mice in the social recognition task. EPM and light-dark box tests showed increased level of anxiety in the group of aged mice comparing to the control group. Fear conditioning protocol revealed impairment of associative learning and memory in the group of aged mice, particularly, fear memory consolidation was dramatically suppressed. Analysis of behavioral factors, social interactions and anxiety level in the experimental mice has confirmed age-related neurodegeneration in the 1st group. We found that the most informative approach to identifying neurological impairments in aging mice (social interaction deficit, limitation of interests, increased level of anxiety) should be based on the open field test light-dark box test, and Fear conditioning protocol. Such combination allows obtaining new data on behavioral alterations in the age-associated of neurodegeneration and to develop novel therapeutic strategies for the treatment of age-related brain pathology.

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

There are various types of oral mucosa specific to different parts of the mouth and each of these has a unique histological structure. The variations in the epithelial structure are consistently related to observable differences in the underlying microcirculation: i.e. differences in the course, conformation, and density of capillaries. The aim of this research has been to investigate oral microcirculatory differences between men and women as well as between various age groups, in order to map the oral mucosa, and to highlight changes occurring during aging. A total of 45 healthy subjects were enrolled for this study (12 men and 33 women; mean age 60.37; range 30-82). A complete in-vivo videocapillaroscopic mapping of the oral mucosa was done on each subject. The capillaroscopic patterns of the various areas differ particularly in the course of the loops in relation to the mucosal surface. On the basis of statistical analysis of the collected data, it emerges that there are many differences in capillary loop density between men and women and between different age groups. This study demonstrates the necessity of approaching the investigation of patient microcirculation in different ways depending on sex or age.

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

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

Objective: To examine neurodegenerative imaging biomarkers in Alzheimer disease (AD) dementia from middle to old age. Methods: Persons with AD dementia and elevated brain β-amyloid with Pittsburgh compound B (PiB)-PET imaging underwent [18F]-fluorodeoxyglucose (FDG)-PET and structural MRI. We evaluated 3 AD-related neurodegeneration biomarkers: hippocampal volume adjusted for total intracranial volume (HVa), FDG standardized uptake value ratio (SUVR) in regions of interest linked to AD, and cortical thickness in AD-related regions of interest. We examined associations of each biomarker with age and evaluated age effects on cutpoints defined by the 90th percentile in AD dementia. We assembled an age-, sex-, and intracranial volume-matched group of 194 similarly imaged clinically normal (CN) persons. Results: The 97 participants with AD dementia (aged 49–93 years) had PiB SUVR ≥1.8. A nonlinear (inverted-U) relationship between FDG SUVR and age was seen in the AD group but an inverse linear relationship with age was seen in the CN group. Cortical thickness had an inverse linear relationship with age in AD but a nonlinear (flat, then inverse linear) relationship in the CN group. HVa showed an inverse linear relationship with age in both AD and CN groups. Age effects on 90th percentile cutpoints were small for FDG SUVR and cortical thickness, but larger for HVa. Conclusions: In persons with AD dementia with elevated PiB SUVR, values of each neurodegeneration biomarker were associated with age. Cortical thickness had the smallest differences in 90th percentile cutpoints from middle to old age, and HVa the largest differences. PMID:27421543

Previously, increasing age has been a part of the exclusion criteria used when determining eligibility for a pancreas transplant. However, the analysis of pancreas transplantation outcomes based on age groupings has largely been based on single-center reports. A UNOS database review of all adult pancreas and kidney-pancreas transplants between 1996 and 2012 was performed. Patients were divided into groups based on age categories: 18-29 (n = 1823), 30-39 (n = 7624), 40-49 (n = 7967), 50-59 (n = 3160), and ≥60 (n = 280). We compared survival outcomes and demographic variables between each age grouping. Of the 20 854 pancreas transplants, 3440 of the recipients were 50 yr of age or above. Graft survival was consistently the greatest in adults 40-49 yr of age. Graft survival was least in adults age 18-29 at one-, three-, and five-yr intervals. At 10- and 15-yr intervals, graft survival was the poorest in adults >60 yr old. Patient survival and age were found to be inversely proportional; as the patient population's age increased, survival decreased. Pancreas transplants performed in patients of increasing age demonstrate decreased patient and graft survival when compared to pancreas transplants in patients <50 yr of age. © 2014 John Wiley & Sons A/S.

Age is associated with reduced exercise capacity and greater prevalence of coronary artery disease. Whether the prognostic information obtained from dobutamine stress echocardiography (DSE), a stress test commonly used for patients unable to perform an exercise test, provides differential information based on age is not well known. We studied 6,655 consecutive patients referred for DSE. Patients were divided into 3 age groups: (1) <60 years (n = 1,389), (2) 60 to 74 years (n = 2,978), and (3) ≥75 years (n = 2,288). Mean follow-up was 5.5 ± 2.8 years. End points included all-cause mortality and cardiac events, including myocardial infarction and late (>3 months) coronary revascularization. Peak stress wall motion score index was an independent predictor of cardiac events in all age groups (<60 years: hazard ratio [HR] 1.14, P = .02; 60-74 years: HR 1.70, P < .0001; ≥75 years: HR 1.10, P = .006). In patients ≥75 years, peak wall motion score index (HR 1.10, P < .0001) and abnormal left ventricular end-systolic volume response (HR 1.25, P = .03) were independent predictors of death. In patients aged 60 to 74 years, abnormal left ventricular end-systolic volume response (HR 1.43, P = .0003) was independently related to death, whereas in patients <60 years, the echocardiographic data assessed during stress were not a predictor. Dobutamine stress echocardiography provided independent information predictive of cardiac events among all age groups and death in patients ≥60 years. However, among patients <60 years, stress-induced echocardiographic abnormalities were not independently associated with mortality. Comorbidities, which have precluded exercise testing, may be most relevant in predicting mortality in patients <60 years undergoing DSE. Copyright © 2011 Mosby, Inc. All rights reserved.

Measurement of sexual function typically uses self-report, which, to work as intended, must use language that is understood consistently by diverse respondents. Commonly used measures employ multiple terms, primarily (sexual) interest, desire, and arousal, that might not be understood in the same way by laypeople and professionals. To inform self-reported measurement efforts for research and clinical settings by examining how US men and women recruited from a health care setting understand and interpret different terms. We conducted 10 focus groups in Durham, NC (N = 57). Discussions were audio-recorded and transcribed, and the content of the discussions was systematically analyzed in 2 phases of coding by the research team, facilitated by Nvivo qualitative analysis software (QSR International, Doncaster, VIC, Australia). Patient focus group discussions about the meanings and connotations of multiple terms related to sexual function, especially interest, desire, and arousal. 5 groups included male participants and 5 included female participants. Participants characterized (sexual) interest as a cognitive phenomenon and a situational response to a specific person. Similarly, they characterized (sexual) desire as a situational person-specific experience with some support for it as a cognitive phenomenon but more support for it as a physical phenomenon. In contrast, participants characterized sexual arousal as a physical phenomenon occurring in response to physical or visual stimulation and not related to a specific person. These results can help us understand how laypeople are using and responding to these terms when they are used in clinical and research settings. Patient participants in these groups were diverse in age, gender, sexual orientation, and health, with the potential to voice diverse perspectives on sexual functioning; however, the sample was limited to a single city in the southeastern United States. The meanings of interest, desire, and arousal were

The aim of the study was to carry out a cross-sectional study of 124 cognitively normal Chinese adults using the voxel-based morphometry approach to delineate age-related changes in the gray matter volume of regions of interest (ROI) in the brain and further analyze their correlation with age. One hundred twenty-four cognitively normal adults were divided into the young age group, the middle age group, and the old age group. Conventional magnetic resonance imaging was performed with the Achieva 3.0 T system. Structural images were processed using VBM8 and SPM8. Regions of interest were obtained by WFU PickAtlas and all realigned images were spatially normalized. Females showed significantly greater total gray matter volume than males (t = 4.81, P = 0.0000, false discovery rate corrected). Compared with young subjects, old-aged subjects showed extensive reduction in gray matter volumes in all ROIs examined except the occipital lobe. In young- and middle-aged subjects, female and male subjects showed significant difference in the right middle temporal gyrus, right superior temporal gyrus, left angular gyrus, right middle occipital lobe, left middle cingulate gyrus, and the pars triangularis of the right inferior frontal gyrus, suggesting an interaction between age and sex (P < 0.001, uncorrected). Logistic regression analysis revealed linear negative correlation between the total gray matter volume and age (R = 0.529, P < 0.001). Significant age-related differences are present in gray matter volume across multiple brain regions during aging. The VPM approach may provide an emerging paradigm in the normal aging brain that may help differentiate underlying normal neurobiological aging changes of specific brain regions from neurodegenerative impairments.

Trends in the use of mechanical circulatory support as a bridge to heart transplantation across different age groups.

Numerous cohort analyses suggest rapidly increasing use of mechanical circulatory support (MCS) as a bridge to heart transplantation (HTx), but the role of age in selection for MCS remains unknown. We assessed adult HTx in the International Society for Heart And Lung Transplantation Registry between 2005 and 2013 and we determined MCS use by recipient age group and transplant year. Multivariable logistic regression models were constructed to identify variables associated with continuous flow (CF) left ventricular assist device (LVAD) use within each age group. Among 16,480 HTx recipients the percentage of overall MCS use increased from 23% to 38%, 21% to 41%, and 17% to 42% in age groups 18-39 years, 40-59 years and over 60 years, respectively. This effect was mainly due to an increase in CF LVAD use and primarily in HTx recipients aged over 60. In multivariable analyses, male gender and blood group O were significantly associated with CF LVAD use in all age groups. Bridge to transplant MCS use increased dramatically between 2005 and 2013 primarily due to increased use of CF LVAD and primarily in higher ages. Pre-HTx CF LVAD use was more frequent in men and blood group O. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

Indirect costs of the interview tour can be prohibitive. The authors sought to assess the desire of interviewees to mitigate these costs through ideas such as sharing hotel rooms and transportation, willingness to stay with local students, and the preferred modality to coordinate this collaboration. A survey link was posted on the Uncle Harvey website and the Facebook profile page of fourth-year medical students from 6 different medical schools shortly after the 2014 match day. There were a total of 156 respondents to the survey. The majority of the respondents were postinterview medical students (65.4%), but preinterview medical students (28.2%) and current residents (6.4%) also responded to the survey. Most respondents were pursuing a field other than neurosurgery (75.0%) and expressed a desire to share a hotel room and/or transportation (77.4%) as well as stay in the dorm room of a medical student at the program in which they are interviewing (70.0%). Students going into neurosurgery were significantly more likely to be interested in sharing hotel/transportation (89.2% neurosurgery vs 72.8% nonneurosurgery; p = 0.040) and in staying in the dorm room of a local student when on interviews (85.0% neurosurgery vs 57.1% nonneurosurgery; p = 0.040) than those going into other specialties. Among postinterview students, communication was preferred to be by private, email identification-only chat room. Given neurosurgery resident candidates' interest in collaborating to reduce interview costs, consideration should be given to creating a system that could allow students to coordinate cost sharing between interviewees. Moreover, interviewees should be connected to local students from neurosurgery interest groups as a resource.

Prevalence of self-reported food allergy in different age groups of georgian population.

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. The data has provided the first epidemiological information related to food allergy among children and adults in Georgia. Results should serve as baseline information for food allergy screening, diagnosis and treatment. Our findings can also inform the public health officials on the disease burden and may offer some

Restricted interests are a class of repetitive behavior in autism spectrum disorders (ASD) whose intensity and narrow focus often contribute to significant interference with daily functioning. While numerous neuroimaging studies have investigated executive circuits as putative neural substrates of repetitive behavior, recent work implicates affective neural circuits in restricted interests. We sought to explore the role of affective neural circuits and determine how restricted interests are distinguished from hobbies or interests in typical development. We compared a group of children with ASD to a typically developing (TD) group of children with strong interests or hobbies, employing parent report, an operant behavioral task, and functional imaging with personalized stimuli based on individual interests. While performance on the operant task was similar between the two groups, parent report of intensity and interference of interests was significantly higher in the ASD group. Both the ASD and TD groups showed increased BOLD response in widespread affective neural regions to the pictures of their own interest. When viewing pictures of other children's interests, the TD group showed a similar pattern, whereas BOLD response in the ASD group was much more limited. Increased BOLD response in the insula and anterior cingulate cortex distinguished the ASD from the TD group, and parent report of the intensity and interference with daily life of the child's restricted interest predicted insula response. While affective neural network response and operant behavior are comparable in typical and restricted interests, the narrowness of focus that clinically distinguishes restricted interests in ASD is reflected in more interference in daily life and aberrantly enhanced insula and anterior cingulate response to individuals' own interests in the ASD group. These results further support the involvement of affective neural networks in repetitive behaviors in ASD. © 2013 The

A test of occupational stress in different gender, age, work duration, educational level and marital status group, was carried out with revised occupational stress inventory (OSI-R) for 4278 participants. The results of gender show that there are heavier occupational role, stronger interpersonal and physical strain in male than that in female, and the differences are statistically significant (P < 0.01). The score of recreation in the male is higher than that in female, but the score of self-care in the female is higher than that in male, and the differences are statistically significant (P < 0.01). Difference in the scores of occupational role, personal resource among various age groups is significant (P < 0.01). Vocational, interpersonal strain scores among various age groups is significant (P < 0.05). The results of educational level analyses suggest that the difference in the scores of occupational stress and strain among various educational levels show statistically significant (P < 0.05), whereas there are no statistic significance of coping resources among the groups (P > 0.05).

However, most studies investigating barrier factors and motivation for participation in recreational sports have been limited to specific areas (e.g., a city or school) or demographic groups (e.g., adolescents). Therefore, this study set out to gain a more comprehensive understanding of the behavioral and socioeconomic factors influencing interest in recreational sports participation in Taiwan, as well as to evaluate the effect of any urban-rural divide. Methods This study analyzed data collected by the “Taiwan Social Change Survey” (program five, wave 3) “Leisure Life” questionnaire. We used hierarchical linear modeling to assess respondent interest in recreational sports participation and evaluated the influence of behavioral factors, socioeconomic factors, and residence location (urban/rural). Results Of the 2,146 participants in this study, 50.3% were male, and the average age was 43.9 years. Location of residence (urban/rural) accounted for 35.3% of the variation in interest in recreational sports participation, while the remaining 64.7% came from the individual level. Participants who lived in rural settings were less interested in recreational sports than their urban counterparts. Gender, educational attainment, participation frequency, health-motivated interest, and appearance-motivated interest were also associated with interest in recreational sports participation. Conclusions Different communication strategies may be needed to effectively reach different demographic groups. We suggest that future public health campaigns aiming to increase recreational sports participation include tailored interventions and messages to effectively encourage leisure physical activities among all, regardless of demographic boundaries.

Little is known about the relationship between implant patient mortality compared to reference populations. The aim of this study was to report the mortality pattern in patients treated with dental implants up to a 15-year period, and to compare this to mortality in reference populations with regard to age at surgery, sex, and degree of tooth loss. Patient cumulative survival rate (CSR) was calculated for a total of 4,231 treated implant patients from a single clinic. Information was based on surgical registers in the clinic and the National Population Register in Sweden. Patients were arranged into age groups of 10 years, and CSR was compared to that of the reference population of comparable age and reported in relation to age at surgery, sex, and type of jaw/dentition. A similar, consistent, general relationship between CSR of different age groups of implant patients and reference populations could be observed for all parameters studied. Completely edentulous patients presented higher mortality than partially edentulous patients (P < .05). Furthermore, implant patients in younger age groups showed mortality similar to or higher than reference populations, while older patient age groups showed increasingly lower mortality than comparable reference populations for edentulous and partially edentulous patients (P < .05). A consistent pattern of mortality in different age groups of patients compared to reference populations was observed, indicating higher patient mortality in younger age groups and lower in older groups. The reported pattern is not assumed to be related to implant treatment per se, but is assumed to reflect the variation in general health of a selected subgroup of treated implant patients compared to the reference population in different age groups.

According to the peak and decline model divergent thinking declines at a specific age (in or after middle age). However, if divergent thinking declines steadily in aging still has to be clarified. In order to explore the age-related changes in verbal and visual divergent thinking, in the present study a sample of 159 participants was divided in five age groups: young adults (18-35 years), middle-aged adults (36-55), young old (56-74), old (75-85) and the oldest-old (86-98). Two divergent thinking tasks were administered: the alternative uses for cardboard boxes, aimed at assessing verbal ideational fluency, flexibility and originality; the completion drawing task, aimed at assessing visual ideational fluency, flexibility and originality. Results showed that after peaking in the young adult group (20-35 years) all components of verbal and visual divergent thinking stabilized in the middle-aged adult group (36-55 years) and then started declining in the young old group (56-75). Interestingly, all components were found to be preserved after declining. Yet, verbal and visual divergent thinking were found at the same extent across age groups, with the exception of visual ideational fluency, that was higher in the young old group, the old group and the oldest-old group than verbal ideational fluency. These results support the idea that divergent thinking does not decline steadily in the elderly. Given that older people can preserve to some extent verbal and visual divergent thinking, these findings have important implications for active aging, that is, divergent thinking might be fostered in aging in order to prevent the cognitive decline.

An Item Response Theory Analysis of DSM–IV Personality Disorder Criteria Across Younger and Older Age Groups

Many of the Diagnostic and Statistical Manual of Mental Disorders, 4th edition (DSM–IV; American Psychiatric Association, 1994) personality disorder (PD) diagnostic criteria focus on a younger social and occupational context. The absence of age-appropriate criteria for older adults forces researchers and clinicians to draw conclusions based on existing criteria, which are likely inadequate. To explore which DSM–IV PD criteria contain age group measurement bias, the authors report 2 analyses of data on nearly 37,000 participants, ages 18–98 years, taken from a public data set that includes 7 of the 10 PDs (antisocial, avoidant, dependent, histrionic, obsessive–compulsive, paranoid, and schizoid). The 1st analysis revealed that older age groups tend to endorse fewer PD criteria than younger age groups. The 2nd analysis revealed that 29% of the criteria contain measurement bias. Although the latent variable structure for each PD was quite similar across younger and older age groups, some individual criteria were differentially endorsed by younger and older adults with equivalent PD pathology. The presence of measurement bias for these criteria raises questions concerning the assessment of PDs in older adults and the interpretation of existing data. PMID:17385993

Changes in occlusal vertical dimension (OVD) and age have been found to affect Smile Index (SI, width/height of smile). Limited information is available regarding the aesthetic effects of these changes. The objective of this study was to evaluate the attractiveness of digitally manipulated smile images with differences in SI and incisal edge position (IEP) judged by respondents in different age groups. A total of 12 smile images were generated with varying SI (3·5, 5·3, 7·2, 9·0) and IEP (High, Medium, Low). Fifty respondents each in four age groups (15-24, 25-39, 40-54, 55+) evaluated the attractiveness of the 12 images using a 0-10 visual analog scale (VAS, 10 being most attractive). A repeated-measures three-factorial mixed model assessed differences. SI, IEP and age of respondents were found to significantly influence attractiveness score (P < 0·01 for all). With all age groups combined, SI = 7·2/IEP = Medium was most attractive (VAS = 7·22), followed by SI = 9·0/IEP = Medium, and SI = 5·3/IEP = Medium (VAS = 6·53 and 6·48, respectively). SI = 3·5/IEP = High and SI = 3·5/IEP = Low were least attractive (VAS = 1·99 and VAS = 2·58, respectively). Age group significantly influenced aesthetic perception, with younger respondents more critical in differences in SI and IEP. SI and IEP significantly influenced attractiveness of the smile in all respondent age groups. Low SI (i.e. 3·5) combined with high or low IEP was unattractive. Medium SI to high SI (i.e. 5·3-9·0) combined with medium IEP were considered attractive. © 2016 John Wiley & Sons Ltd.

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.

It is well recognised that the adoption and longer term adherence to physical activity by adults to reduce the risk of chronic disease is a challenge. Interventions, such as group and home based physical activity programs, have been widely reported upon. However few studies have directly compared these interventions over the longer term to determine their adherence and effectiveness. Participant preference for home based or group interventions is important. Some evidence suggests that home based physical activity programs are preferred by middle aged adults and provide better long term physical activity adherence. Physiotherapists may also be useful in increasing physical activity adherence, with limited research on their impact. 'Physical Activity at Home' is a 2 year pragmatic randomised control trial, with a non-randomised comparison to group exercise. Middle-aged adults not interested in, or unable to attend, a group exercise program will be targeted. Sedentary community dwelling 50-65 year olds with no serious medical conditions or functional impairments will be recruited via two mail outs using the Australian federal electoral roll. The first mail out will invite participants to a 6 month community group exercise program. The second mail out will be sent to those not interested in the group exercise program inviting them to take part in a home based intervention. Eligible home based participants will be randomised into a 6 month physiotherapy-led home based physical activity program or usual care. Outcome measures will be taken at baseline, 6, 12, 18 and 24 months. The primary outcome is physical activity adherence via exercise diaries. Secondary outcomes include the Active Australia Survey, accelerometry, aerobic capacity (step test), quality of life (SF-12v2), blood pressure, waist circumference, waist-to-hip ratio and body mass index. Costs will be recorded prospectively and qualitative data will be collected. The planned 18 month follow-up post

To compare the complications associated with age and technique groups in patients undergoing pectus excavatum (PE) repair. The data of 994 patients who underwent PE repair from March 2011 to December 2015 were retrospectively reviewed. Mean age was 9.59 years (range 31 months-55 years), and 756 patients were men (76.1%). The age groups were defined as follows: Group 1, <5 years; Group 2, 5-9 years; Group 3, 10-14 years; Group 4, 15-17 years; Group 5, 18-19 years; Group 6, 20-24 years; and Group 7, >24 years. The technique groups were defined as follows: Group 1, patients who underwent repair with claw fixators and hinge plates; Group 2, patients who underwent repair with our 'bridge' technique. Complications were compared between age groups and technique groups. No cases of mortality occurred. Complication rates in the age groups 1-7 were 5.4%, 3.6%, 12.1%, 18.2%, 17.3%, 13.9% and 16.7%, respectively. The complication rate tripled after the age of 10. In multivariable analysis, odds ratio of Groups 4, 5 and 7 and asymmetric types were 3.04, 2.81, 2.97 and 1.70 (P < 0.01, P = 0.02, 0.03 and 0.03, respectively). The bar dislocation rate in technique Group 1 was 0.8% (6 of 780). No bar dislocations occurred in technique Group 2. Older patients have more asymmetric pectus deformity and they are also risk factors for complications following PE repair. The bridge technique provides a bar dislocation rate of 0%, even in adult patients. This procedure seems to reduce or prevent major complications following PE repair. © The Author 2017.

Objectives: A gluten-free diet is the treatment for celiac disease, but pharmaceutical agents are being developed. The level of interest amongst patients in using a medication to treat celiac disease is unknown. This study examined the level of interest amongst patients in medication to treat celiac disease. Methods: A questionnaire was distributed to celiac disease patients and data were collected on demographics, presentation, and interest in medication. Three validated celiac disease-specific instruments were incorporated: Celiac Disease Associated Quality of Life, the Celiac Symptom Index, and the Celiac Dietary Adherence Test. Results: Responses were received from 365 individuals with biopsy-proven celiac disease. Respondents were 78% (n = 276) female, 48% (n = 170) over 50 years of age, and experienced a classical (diarrhea predominant) presentation in 44% (n = 154). Of the 339 individuals answering the question regarding use of a medication to treat celiac disease, 66% were interested. Interest was greatest in older individuals (71% >50 years of age versus 60% <50 years of age, p = 0.0415), men (78% men versus 62% women, p = 0.0083), frequent restaurant customers (76% versus 58%, p = 0.0006), those dissatisfied with their weight (73% versus 51%, p = 0.0003) and those concerned with the cost of a gluten-free diet (77% versus 64%, p = 0.0176). Length of time since diagnosis, education, presentation, and symptoms with gluten exposure did not demonstrate any effect. Interest in medication was associated with a worse quality of life (CD-QOL 69.4 versus 80.1, p < 0.0001). Conclusions: Most individuals with celiac disease are interested in using a medication. Interest was highest among men, older individuals, frequent restaurant customers, individuals dissatisfied with their weight or concerned with the cost of a gluten-free diet, and those with a worse quality of life.

Risk, interest groups and the definition of crisis: the case of volcanic ash.

PubMed

Hutter, Bridget M; Lloyd-Bostock, Sally

2013-09-01

This paper considers a key aspect of the 'risk society' thesis: the belief that we should be able to manage risks and control the world around us. In particular it focuses on the interface between risk and risk events as socially constructed and the insights that 'critical situations' give us into 'the routine and mundane', the otherwise taken for granted assumptions underlying risk regulation. It does this with reference to the events precipitated by the April 2010 volcanic eruption in the Eyjafjallajökull area of Iceland. The resulting cloud of volcanic ash spread across Europe and much of Europe's airspace was closed to civil aviation for six days, with far reaching consequences including huge financial losses for airlines. The social processes of defining and reacting to risk and crisis both reveal and generate dilemmas and challenges in regulation. This paper examines the role of different interest groups in defining risk expectations and thereby redefining the ash crisis as a regulatory crisis. © London School of Economics and Political Science 2013.

Behavior analysis and the study of human aging

PubMed Central

Derenne, Adam; Baron, Alan

2002-01-01

As the population of older adults continues to rise, psychologists along with other behavioral and social scientists have shown increasing interest in this age group. Although behavior analysts have contributed to research on aging, the focus has been on applications that remedy age-related deficits, rather than a concern with aging as a developmental process. In particular, there has been little interest in the central theoretical questions that have guided gerontologists. How does behavior change with advancing years, and what are the sources of those changes? We consider the possibility that this neglect reflects the long-standing commitment of behavior analysts to variables that can be experimentally manipulated, a requirement that excludes the key variable—age itself. We review the options available to researchers and present strategies that minimize deviations from the traditional features of behavior-analytic designs. Our comments are predicated on the view that aging issues within contemporary society are far too important for behavior analysts to ignore. PMID:22478383

Effect of Age Group on Technical-Tactical Performance Profile of the Serve in Men's Volleyball.

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

Lower Paleozoic Through Archean Detrital Zircon Ages From Metasedimentary Rocks of the Nome Group, Seward Peninsula, Alaska

Amato, J. M.; Miller, E. L.; Gehrels, G.

2003-12-01

Metamorphic rocks of Seward Peninsula have been divided into two groups based on their metamorphic grade and history: The Nome Group and the Kigluaik Group. Although it is sometime been assumed that the higher structural position of the Nome Group versus the Kigluaik Group indicates the Kigluaik Group is older, this relationship and the age of the protoliths of these rocks has never been well-established. The Nome Group includes (delete the) lower grade blueschist and greenschist facies rocks which are widespread across the Seward Peninsula (delete) Rock types include pelitic schist, more mafic chlorite-white mica-albite schist, marble, quartzite, and metabasite. An early metamorphic event (pre-120 Ma) occurred at high pressure and relatively low temperature, and is everywhere overprinted by younger deformation and greenschist facies Rare eclogite facies assemblages are preserved in metabasites, and garnet-glaucophane in some of the pelitic schists. The Kigluaik Group includes upper greenschist to granulite facies rocks that are exposed in the core of a gneiss dome. They record a younger event (~91 Ma) that occurred at higher temperatures and resulted in partial thermal overprinting of the Nome Group and upper greenschist to granulite facies assemblages forming in the Kigluaik Group. The Kigluaik Group and equivalent rocks in the Bendeleben and Darby Mountains represent at least in part similar protoliths to many of the units in the Nome Group (Till and Dumoulin, 1994). The boundary between the rocks of the Nome Group and those clearly affected by the second metamorphic event is placed arbitrarily at the "Biotite-in" isograd along the flanks of the gneiss dome. In order to assess the protolith ages and source rock ages for these units, detrital zircon ages were obtained from three samples from the Nome Group, with Kigluaik Group ages forthcoming. LA-MC-ICPMS U/Pb isotope analysis was used for dating. Two samples were collected from the western Kigluaik Mountains

Interest Group Conflict Over Medicaid Expansion: The Surprising Impact of Public Advocates.

Callaghan, Timothy; Jacobs, Lawrence R

2016-02-01

We examined the potential economic, policy, and political influences on the decisions of the 50 US states to expand Medicaid under the Affordable Care Act. We related a measure of relative state progress toward Medicaid expansion updated to 2015 to each state's economic circumstances, established policy frameworks in states, partisan control of state government, and lobbyists for businesses, medical professionals, unions, and public interest organizations. The 9201 lobbyists working on health care reform in state capitols exerted a strong and significant impact on Medicaid expansion. Controlling for confounding factors (including partisanship and existing policy frameworks), we found that business and professional lobbyists exerted a negative effect on state Medicaid expansion and, unexpectedly, that public interest advocates exerted a positive effect. There are 3.1 million adults who lack coverage because they live in the 20 states that refused to expand Medicaid. Although political party and lobbyists for private interests present significant barriers in these states, legislative lobbying on behalf of the uninsured appears likely to be effective.

Pattern of injury mortality by age-group in children aged 0-14 years in Scotland, 2002-2006, and its implications for prevention.

Knowledge of the epidemiology of injuries in children is essential for the planning, implementation and evaluation of preventive measures but recent epidemiological information on injuries in children both in general and by age-group in Scotland is scarce. This study examines the recent pattern of childhood mortality from injury by age-group in Scotland and considers its implications for prevention. Routine mortality data for the period 2002-2006 were obtained from the General Register Office for Scotland and were analysed in terms of number of deaths, mean annual mortality rates per 100,000 population, leading causes of death, and causes of injury death. Mid-year population estimates were used as the denominator. Chi-square tests were used to determine statistical significance. 186 children aged 0-14 died from an injury in Scotland during 2002-06 (MR 4.3 per 100,000). Injuries were the leading cause of death in 1-14, 5-9 and 10-14 year-olds (causing 25%, 29% and 32% of all deaths respectively). The leading individual causes of injury death (0-14 years) were pedestrian and non-pedestrian road-traffic injuries and assault/homicide but there was variation by age-group. Assault/homicide, fire and suffocation caused most injury deaths in young children; road-traffic injuries in older ones. Collectively, intentional injuries were a bigger threat to the lives of under-15s than any single cause of unintentional injury. The mortality rate from assault/homicide was highest in infants (<1 year) and decreased with increasing age. Children aged 5-9 were significantly less likely to die from an injury than 0-4 or 10-14 year-olds (p < 0.05). Suicide was an important cause of injury mortality in 10-14 year-olds. Injuries continue to be a leading cause of death in childhood in Scotland. Variation in causes of injury death by age-group is important when targeting preventive efforts. In particular, the threats of assault/homicide in infants, fire in 1-4 year-olds, pedestrian injury

In this commentary on Nye, Su, Rounds, and Drasgow (2012) and Schmidt (2011), I address the value of occupational interest inventories for understanding sex differences in occupational choice and the extent to which occupational interests are malleable. In particular, I argue (a) that some subscales in interest inventories are too heterogeneous to be given a single label and that the labels that are applied to some subscales are inaccurate and misleading; (b) that "things versus people" is an inaccurate and misleading characterization of a dimension that is frequently associated with interest inventories and linked to sex differences; (c) that vocational interests will be valid predictors of job performance primarily in cases in which the job has been held for some time by a diverse group of people and not in cases in which jobholders have been homogeneous; (d) that sex differences in interests are malleable and sensitive to small and subtle environmental cues; and (e) that women's interest in math and science will increase if they have a feeling of belonging and an expectation of success. © The Author(s) 2014.

To investigate (a) differences in work characteristics and (b) determinants of job satisfaction among employees in different age groups. A cross-sectional questionnaire was filled in by 1,112 university employees, classified into four age groups. (a) Work characteristics were analysed with ANOVA while adjusting for sex and job classification. (b) Job satisfaction was regressed against job demands and job resources adapted from the Job Demands-Resources model. Statistically significant differences concerning work characteristics between age groups are present, but rather small. Regression analyses revealed that negative association of the job demands workload and conflicts at work with job satisfaction faded by adding job resources. Job resources were most correlated with more job satisfaction, especially more skill discretion and more relations with colleagues. Skill discretion and relations with colleagues are major determinants of job satisfaction. However, attention should also be given to conflicts at work, support from supervisor and opportunities for further education, because the mean scores of these work characteristics were disappointing in almost all age groups. The latter two characteristics were found to be associated significantly to job satisfaction in older workers.

It has been suggested that extrinsic skin ageing manifests differently in Caucasians versus East Asians. In particular, from previous studies it was concluded that Caucasians are more prone to develop wrinkles, whereas pigment spot formation is the hallmark of extrinsic skin ageing in East Asians. However, these assumptions are based on a very limited number of studies which did not include different East Asian populations. We here compare the manifestation of extrinsic skin ageing signs in German, Japanese and Chinese women by specifically elucidating the age and anatomical site dependence of any potential ethnic difference. In the present study, we assessed skin ageing in N=902 German, N=165 Japanese and N=1260 Chinese women ranging from 30 to 90 years by means of SCINEXA™. Linear regression analysis was used to test for ethnic differences and their age and site dependence adjusted for educational level, sun exposure, smoking and sun protection behaviours. Pigment spots and wrinkles on the face were present among all three ethnic groups and differences were influenced by age and anatomical sites independently of further influencing factors. Pigment spots on the forehead were most pronounced over the whole age range in Chinese and German women and least developed in Japanese. Pigment spots on cheeks were a typical extrinsic skin an ageing sign in the two East Asian populations in all age groups. However, in older German women they reach the same level as observed in the two East Asian populations. In contrast, pigment spots on arms and hands were significantly more pronounced in German women ≥45years of age. Wrinkles were not exclusively a skin an ageing sign of German women, but were also very pronounced in Chinese women on forehead, between the eyebrows and in the crow's feet area. These results corroborate the previous notion that the occurrence of pigments spots and wrinkles is different between Caucasians and East Asians. In addition, this study shows

This study examines the effect of history-based instruction on the topic of the atom on students' academic achievement and their interest in the history of science, investigating as well the relationship between student interest and academic achievement. The sample of the study consisted of two groups of freshman students from an undergraduate elementary science teachers program. The same chemistry instructor taught the groups, which were randomly assigned as an experimental and a control group. The students in the control group received traditional teacher-centered instruction, while the experimental group students were taught the topic of the atom using history-based instruction enriched with various sources of situational interest such as novelty, autonomy, social involvement, and knowledge acquisition (NASK). Data gathering instruments were the Atom Achievement Test and the History of Science Interest Scale, administered to both of the groups before and after the instruction. The data were analyzed with the independent-samples t test, the paired-samples t test, and one-way ANCOVA statistical analysis. The results showed that the history-based instruction including NASK was more effective than traditional instruction in improving the students' learning of the subject of the atom as well as in stimulating and improving students' interest in the history of science. Further, students with high interest displayed significantly better achievement than students with low interest. The better learning of the topic of the atom was more pronounced in the case of students with a high interest in the history of science compared to students with moderate or low interest.

This paper investigates the effect that texting with WhatsApp, one of the most common applications for instant messaging, exerts on driving performance. Because distracted driving also affects older drivers, who can have seriously compromised vision, we also analysed the associations between visual-function parameters and driving performance. A total of 75 drivers, experienced in sending WhatsApp messages (≥10WhatsApp messages/week), participated in this study and were divided into four age categories. Visual-function tests included contrast sensitivity with and without glare, retinal straylight and objective assessment of optical quality. Simulated driving performance was assessed under a baseline driving condition (without distraction) as well as a texting condition (WhatsApp messages) while driving. The participants used their own mobile phone. Lastly, objective results of driving performance were compared with subjective self-report data from the Driver Behaviour Questionnaire (DBQ). The analysis indicated that functional changes occurring with age, such as a lower contrast sensitivity and greater retinal straylight, were correlated with a higher number of collisions, longer distances driven outside the lane, and greater standard deviation of lateral position (SDLP). The results showed a significant main effect of age for the driving-performance parameters. Also, compared to the baseline, texting WhatsApp messages while driving worsens driving performance for all age groups, most notably among older participants. Thus, the older drivers' SDLP was ∼14% higher than that for the baseline average of all the other drivers and rose to 29% under distraction, reflecting the impact of secondary tasks. The negative effect of the use of the smartphone during driving was also reflected in the number of collisions, with a greater risk of accidents in all the groups of drivers (by 8.3% for young adults, 25.0% for adults, 80.5% for middle-aged adults, and 134.5% for older

Stroke is a leading cause of long-term disability and the fifth leading cause of death in Israel. Knowledge of stroke warning signs has been linked to early seeking of medical help. Little is known about knowledge of stroke warning signs in Israeli Jewish adults. Stroke knowledge was examined among Jewish Israeli adults. Using a structured questionnaire, registered nurses interviewed a convenience sample of the respondents, 18 years or older, with no stroke history. Stroke knowledge and demographics were examined by 3 age groups (<45, 45-64, and >64 years) in men and women. In total, 1137 Jewish Israelis were interviewed, 457 (40.2%) men and 680 women (59.8%); 493 (43.4%) were younger than 45 years, 541 (47.6%) were aged 45 to 64 years, and 102 (9%) were older than 64 years; 1 (0.1%) did not report age. On average, each interview lasted for 25 to 30 minutes. Participants younger than 45 years showed the lowest knowledge of stroke cause. Women younger than 45 years were less likely to identify at least 2 stroke warning signs. Participants younger than 45 years were less likely to identify at least 2 risk factors, compared with participants aged 45 to 64 years and older than 64 years. Women younger than 45 years were less likely to identify at least 2 stroke prevention strategies. Participants younger than 45 years showed the lowest levels of stroke knowledge. The highest stroke knowledge was found in the 45 to 64 years age group. Stroke knowledge among different age groups was similar in both genders. Educational campaigns aimed at increasing knowledge of stroke among the general population and targeting the younger population are recommended.

ABSTRACT Objective: To provide an update on trends in asthma mortality in Brazil for two age groups: 0-4 years and 5-34 years. Methods: Data on mortality from asthma, as defined in the International Classification of Diseases, were obtained for the 1980-2014 period from the Mortality Database maintained by the Information Technology Department of the Brazilian Unified Health Care System. To analyze time trends in standardized asthma mortality rates, we conducted an ecological time-series study, using regression models for the 0- to 4-year and 5- to 34-year age groups. Results: There was a linear trend toward a decrease in asthma mortality in both age groups, whereas there was a third-order polynomial fit in the general population. Conclusions: Although asthma mortality showed a consistent, linear decrease in individuals ≤ 34 years of age, the rate of decline was greater in the 0- to 4-year age group. The 5- to 34-year group also showed a linear decline in mortality, and the rate of that decline increased after the year 2004, when treatment with inhaled corticosteroids became more widely available. The linear decrease in asthma mortality found in both age groups contrasts with the nonlinear trend observed in the general population of Brazil. The introduction of inhaled corticosteroid use through public policies to control asthma coincided with a significant decrease in asthma mortality rates in both subsets of individuals over 5 years of age. The causes of this decline in asthma-related mortality in younger age groups continue to constitute a matter of debate. PMID:28380185

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.

Despite its assumed importance for emotional well-being, studies investigating the positivity effect (PE) in older adults’ information processing rarely tested its relationship with immediate or general affective outcome measures like emotional reactivity or emotional well-being. Moreover, the arousal level of the to-be-processed emotional stimuli has rarely been taken into account as a moderator for the occurrence of the PE and its relationship with affective outcomes. Age group differences (young vs. old) in attention (i.e., fixation durations using eye tracking) and subjective emotional reactions (i.e., pleasantness ratings) were investigated in response to picture stimuli systematically varied in valence (positive vs. negative) and arousal (low vs. high). We examined whether there is a link between age group differences in fixation durations and affective outcomes (i.e., subjective emotional reactions as well as emotional well-being). Older compared to young adults fixated less on the most emotional part in negative but not in positive low-arousing pictures. This age difference did not occur under high arousal. While age group differences in fixation duration did not translate into age group differences in subjective emotional reactions, we found a positive relationship between fixation duration on negative low-arousing pictures and emotional well-being, i.e., negative affect. The present study replicated the well-known PE in attention and emotional reactivity. In line with the idea that the PE reflects top-down-driven processing of affective information, age group differences in fixation durations decreased under high arousal. The present findings are consistent with the idea that age-related changes in the processing of emotional information support older adults’ general emotional well-being. PMID:29163266

Mood and sexual interest changes are commonly cited reasons for discontinuing hormonal contraceptives. Data, however, are inconsistent and limited to adult users. We examined associations of hormonal contraceptive use with mood and sexual interest among adolescents. We recruited 14-17-year-old women from primary care clinics and followed them longitudinally for up to 41 months. Participants completed face-to-face interviews quarterly and two 12-week periods of daily diary collection per year. On daily diaries, participants recorded positive mood, negative mood, and sexual interest. We classified 12-week diary periods as "stable OCP use," "non-use," "initiated use," "stopped use," and "DMPA use" based on self-report of oral contraceptive pill (OCP) use and depot medroxyprogesterone acetate (DMPA) use from medical charts. Diary periods were the unit of analysis. Participants could contribute more than one diary period. We analyzed data using linear models with a random intercept and slope across weeks in a diary period, an effect for contraceptive group, and an adjustment for age at the start of a diary period. Mean weekly positive mood was higher in diary periods characterized by stable OCP use, compared to other groups. Mean weekly negative mood was lower in diary periods characterized by stable OCP use and higher in periods characterized by DMPA use. Periods characterized by stable OCP use additionally showed less mood variation than other groups. Changes in mood among adolescent hormonal contraceptive users differed from those anticipated for adult users. Attention to adolescent-specific changes in mood and sexual interest may improve contraceptive adherence.

Objective To evaluate how malar fat pad (MFP) volumes vary with age, after controlling for gender and body mass index (BMI). Study Design A prospective case-control study evaluating volume of the MFP in women of two age groups. Methods Soft tissue dimensions were measured in eight subjects using magnetic resonance imaging. A multiplanar localizing sequence, followed in sagittal and coronal orientations using a turbo spin echo sequence, was performed to define the MFP. Volumetric calculations were then performed using a 3D image analysis application (Dextroscope, Volume Interactions, Republic of Singapore) to circumscribe areas, orient dimensions, and calculate volumes of the MFP. Results These data reveal no significant difference in the mean (standard deviation) right MFP (p = 0.50), left MFP (p = 0.41), or total MFP (p = 0.45) volumes when comparing the two age groups. In addition, these data indicate that there was no correlation between age and total MFP volume (Pearson correlation coefficient 0.27). Moreover, there was no correlation between age and the ratio of total volume/BMI (Pearson correlation coefficient -0.18). Conclusions Although the sample size of this study was small, these data indicate that ptosis of midfacial fat is more important than volume loss in midfacial aging. These data would suggest repositioning as the primary modality for craniofacial reconstruction.

Objective This multicentre, randomised controlled trial (RCT) aimed to evaluate the efficacy of a small-group intervention promoting successful ageing at work in older nurses (aged ≥45). Method A sample of 115 nurses aged ≥45 from 4 trial sites in Germany were randomly assigned to either the intervention group (IG), that received a small-group intervention of seven weekly sessions of 120 min with a booster session after six weeks or to a wait-list control condition (WLC). Outcomes were measured via validated self-report questionnaires at baseline (T1) and at post-treatment (T2). Primary outcomes were mental health-related well-being and mental health-related quality of life (QOL). The secondary outcomes included mental health-related and work-related measures. Results The intention to treat (ITT) analysis showed significant positive effects of the intervention on mental health. A significant small effect (d = 0.3) in favour of the IG was found for psychological health-related quality of life. Positive small effects (d = 0.24 to d = 0.31) were also found for work related mental strain. Conclusions Our small-group intervention based on a theory of successful ageing for nurses aged ≥45 was found to be effective with regard to improvements of psychological health related quality of life and other mental health-related outcomes. Thus, our study shows that the ageing workforce can be reached through specifically designed preventive interventions. The components of our intervention could be easily adapted to the belongings of other professions. Our results suggest that these components should be evaluated in various settings outside the healthcare sector. PMID:29351310

Institutions, interest groups, and ideology: an agenda for the sociology of health care reform.

Quadagno, Jill

2010-06-01

A central sociological premise is that health care systems are organizations that are embedded within larger institutions, which have been shaped by historical precedents and operate within a specific cultural context. Although bound by policy legacies, embedded constituencies, and path dependent processes, health care systems are not rigid, static, and impervious to change. The success of health care reform in 2010 has shown that existing regimes do have the capacity to respond to new needs in ways that transcend their institutional and ideological limits. For the United States the question is how health care reform will reconfigure the existing network of public and private benefits and the power relationships between the numerous constituencies surrounding them. This article considers how institutions, interest groups, and ideology have affected the organization of the health care system in the United States as well as in other nations. It then discusses issues for future research in the aftermath of the 2009-10 health care reform debate.

Objectives. We examined the potential economic, policy, and political influences on the decisions of the 50 US states to expand Medicaid under the Affordable Care Act. Methods. We related a measure of relative state progress toward Medicaid expansion updated to 2015 to each state’s economic circumstances, established policy frameworks in states, partisan control of state government, and lobbyists for businesses, medical professionals, unions, and public interest organizations. Results. The 9201 lobbyists working on health care reform in state capitols exerted a strong and significant impact on Medicaid expansion. Controlling for confounding factors (including partisanship and existing policy frameworks), we found that business and professional lobbyists exerted a negative effect on state Medicaid expansion and, unexpectedly, that public interest advocates exerted a positive effect. Conclusions. There are 3.1 million adults who lack coverage because they live in the 20 states that refused to expand Medicaid. Although political party and lobbyists for private interests present significant barriers in these states, legislative lobbying on behalf of the uninsured appears likely to be effective.

A congenital adhesion band is a rare condition, but may induce a small bowel obstruction (SBO) at any age. However, only a few sporadic case reports exit. We aimed to identify the clinical characteristics of congenital adhesion band manifesting a SBO stratified by age group between pediatric and adult patients. The medical records of all patients with a SBO between Jan 1, 2009 and Dec 31, 2015 were retrospectively reviewed. Cases associated with previous surgical procedure and cases of secondary obstruction due to inflammatory processes or tumor and other systemic diseases were excluded. The patients were divided into two groups according to age below or above 18 years: pediatric and adult. The basic clinical characteristics were analyzed and compared between groups. Of 251 patients with a SBO, 15 (5.9%) met the inclusion criteria; 10 cases in pediatric group (mean age 17.9 ± 38.7 months) and 5 cases in adult group (mean age 60.0 ± 19.7 years). The pediatric group (66.6%) included 3 neonates, 5 infants, and 2 school children. They usually presented with bilious vomiting (50.0%) and abdominal distention (60.0%), and demonstrated a high rate of early operation (80.0%) and bowel resection (70.0%). In contrast, the adult group (33.3%) presented with abdominal pain (100%) in all cases and underwent a relatively simple procedure of band release using a laparoscopic approach (60%). However, group differences did not reach statistical significance. In addition, two groups did not differ in the time interval to the operation or in the range of the operation (p = 0.089 vs. p = 0.329). No significant correlation was found between the time interval to the operation and the necessity of bowel resection (p = 0.136). There was no mortality in either group. Congenital adhesion band is a very rare condition with diverse clinical presentations across ages. Unlike adult patients, pediatric patients showed a high proportion of early operation and bowel

Online depression communities: members' interests and perceived benefits.

Most previous studies on online communities (peer-to-peer support groups) dedicated to people with depression related to members as a homogeneous group, and none examined differences between segments based on psychographic measures. Such segmentation may be most helpful in understanding members' participation patterns and explaining the benefits members gain from participation. This study aimed to explore whether members of online depression communities vary in their interests in issues discussed in the communities, and if so, whether groups with different interests also differ with regard to the benefits gained from participation. The study was based on an online survey of 793 members of 16 online depression communities. Results identified four member groups: concerned about daily living, information seekers, interested in all topics, and relatively less involved. There were very few differences between the groups in background characteristics, participation patterns, and level of depression. However, results indicated significant differences between the groups in perceived benefits, as the interested in all topics reported more "online support" and "offline improvement" than the information seekers and the relatively less involved, and more "offline improvement" than the concerned about daily living. Assuming that the reported interests reflected actual involvement in discussions of different issues, the findings suggest that combining supportive and informative discussions is more beneficial than attending to only one type of discussion, and stress the importance of informative discussions.

To delineate what type and how much alcohol is purchased from different types of off-licence premises and how this varies across demographic sub-groups, as a basis for public debate and decisions on pricing and planning policies to reduce alcohol-related harm in Australia. The data on alcohol purchasing from off-licence premises are taken from the Australian Alcohol Consumption and Purchasing survey-a nationally representative landline and mobile telephone survey in 2013 on the experiences with alcohol consumption and purchasing of 2020 Australians aged 16+. The present analysis uses data from 1730 respondents who purchased alcohol from off-licence premises in the previous 6 months. The majority (54%) of alcohol purchased from off-licence premises was sold from liquor barns (large warehouse-style alcohol stores), with bottle shops (31%) the second most common outlet. Cask wine was the cheapest alcohol available at off-licence premises in Australia. Respondents in higher alcohol purchasing quintiles and with those with lower income purchased a higher percentage of cheaper alcohol in their total volume of purchasing than lower purchasing quintiles and those with middle and higher income, and younger respondents purchased more expensive alcohol than older age groups. A minimum unit price or increasing alcohol taxes may effectively reduce alcohol purchasing for lower income heavy alcohol purchasers and older age groups from off-licence premise sources, and may be less effective on younger age groups.
