The aim of this study was to calculate and assess the cost of assisted reproductive technology (ART) treatment cycles and live-birth events in Japan in 2010. We performed a retrospective analysis of 238,185 ART cycles, registered with the national registry of assisted reproductive treatment during 2010. Costs were calculated, using a decision analysis model. The average cost per live birth was ¥1,974,000. This varied from ¥1,155,000 in women aged < 30 years to ¥50,189,000 in women aged ≥ 45, which was 29.6 times higher than that of women aged 35-39 years. This rose sharply in the early 40s and upwards. Public funding per live birth was ¥442,000. This was ¥6,118,000 in women aged ≥ 45, 15.4 times higher than that of the 35-39-year-old age group. The costs and public funding of a live birth after ART treatment rises with age due to the lower success rates in older women. It may provide economic background to improve the current subsidy system for ART and to provide practical knowledge about fertility for the general population. © 2014 The Authors.

Social immunity and the evolution of group living in insects.

PubMed

Meunier, Joël

2015-05-26

The evolution of group living requires that individuals limit the inherent risks of parasite infection. To this end, group living insects have developed a unique capability of mounting collective anti-parasite defences, such as allogrooming and corpse removal from the nest. Over the last 20 years, this phenomenon (called social immunity) was mostly studied in eusocial insects, with results emphasizing its importance in derived social systems. However, the role of social immunity in the early evolution of group living remains unclear. Here, I investigate this topic by first presenting the definitions of social immunity and discussing their applications across social systems. I then provide an up-to-date appraisal of the collective and individual mechanisms of social immunity described in eusocial insects and show that they have counterparts in non-eusocial species and even solitary species. Finally, I review evidence demonstrating that the increased risks of parasite infection in group living species may both decrease and increase the level of personal immunity, and discuss how the expression of social immunity could drive these opposite effects. By highlighting similarities and differences of social immunity across social systems, this review emphasizes the potential importance of this phenomenon in the early evolution of the multiple forms of group living in insects. © 2015 The Author(s) Published by the Royal Society.

We provide a methodology for estimating counts of single-year-of-age live-births, fetal-losses, abortions, and pregnant women from aggregated age-group counts. As a case study, we estimate counts for the 254 counties of Texas for the year 2010. We use interpolation to estimate counts of live-births, fetal-losses, and abortions by women of each single-year-of-age for all Texas counties. We then use these counts to estimate the numbers of pregnant women for each single-year-of-age, which were previously available only in aggregate. To support public health policy and planning, we provide single-year-of-age estimates of live-births, fetal-losses, abortions, and pregnant women for all Texas counties in the year 2010, as well as the estimation method source code.

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.

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.

The relationships between live weight and eight body measurements of West African Dwarf (WAD) goats were studied using 211 animals under farm condition. The animals were categorized based on age and sex. Data obtained on height at withers (HW), heart girth (HG), body length (BL), head length (HL), and length of hindquarter (LHQ) were fitted into simple linear, allometric, and multiple-regression models to predict live weight from the body measurements according to age group and sex. Results showed that live weight, HG, BL, LHQ, HL, and HW increased with the age of the animals. In multiple-regression model, HG and HL best fit the model for goat kids; HG, HW, and HL for goat aged 13-24 months; while HG, LHQ, HW, and HL best fit the model for goats aged 25-36 months. Coefficients of determination (R(2)) values for linear and allometric models for predicting the live weight of WAD goat increased with age in all the body measurements, with HG being the most satisfactory single measurement in predicting the live weight of WAD goat. Sex had significant influence on the model with R(2) values consistently higher in females except the models for LHQ and HW.

Due to life-enhancing effects of antiretroviral therapy, HIV-positive persons have the potential for long life comparable to their uninfected peers. Older women (age 50+) living with HIV (OWLH) are often an under-recognized aging group. We conducted a systematic review to examine psychosocial factors that impact how OWLH live, cope, and age with HIV. Initial key word search yielded 1527 records, and 21 studies met our inclusion criteria of original quantitative or qualitative research published between 2013 and 2016 with results specific to OWLH. These focused on health care and self-management, sexual health and risk, stigma, loneliness, mental health (depression, substance use), and protective factors (coping, social support, well-being). Due to the scarcity of studies on each topic and inconclusive findings, no clear patterns of results emerged. As the number of OWLH continues to grow, more research, including longitudinal studies, is needed to fully characterize the psychosocial factors that impact aging with HIV.

[Marital status and place of living as social determinants of vertebral pain syndrome and disturbance of life quality in women of older age groups.

In order to study the role of the marital status and place of residence, as the social determinants of the development of vertebral pain syndrome and related disorders of life activity, the results of a survey of 148 postmenopausal women aged 50-69 years were analyzed. Respondents were divided into groups depending on their marital status (living in a family with husbands and other relatives, only with husbands or alone) and places of residence (in rural or urban areas). The results of this study suggest that family status and place of residence in women of older age groups do not directly influence on the back pain, however they contribute to impairment of vital functions associated with back pain, in particular, psychological state, general activity, working capacity, and also stipulate a higher frequency of requests for medical care and hospitalizations. In single women the level of disruption of daily activity is significantly higher, although the incidence of disability in doing household chores is significantly lower than in married women. Single women reliably seek medical help more often and are hospitalized throught back pain. It was also found the significant correlations between the place of residence and the frequency of health problems related to back pain, psychological and mood disorders, general activity, relationships with others, daily disability in work, impaired ability to move and the frequency of medical help seeking throught back pain. In conclusion, ite should be taken into account in planning of treatment and rehabilitation of women of older age groups with back pain.

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

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.

While in its early years the HIV epidemic affected primarily the male and the young, nowadays, the population living with HIV/AIDS is approximately 24% women, and its age composition has shifted towards older ages. Many of the older women who live with HIV/AIDS also live with the medical and social conditions that accompany aging. This work aims to identify and characterize empirical studies of strategies for the comprehensive management of women over 40, including transgender women, who live with HIV/AIDS. Forty was chosen as an operational age cutoff to identify premenopausal women who are less likely to bear children, as well as peri- and postmenopausal women. We conducted a literature search after discussions with a diverse panel of content experts and other stakeholders and developed an evidence map that identified 890 citations that address questions having to do with programs and barriers to engaging with programs, as well as the role of insurance and comorbidities, and have enrolled older women who live with HIV/AIDS. Of these, only 37 (4%) reported results of interest for women over 40 who live with HIV/AIDS, or examined interactions between gender and older age that would allow predictions in this subgroup. Few of the 37 eligible studies focused on women facing obvious challenges, such as immigrants, transgender, physically abused, or those recently released from prison. No studies focused on women caring for dependents, including children and grandchildren, or those diagnosed after age 40. The evidence base that is directly applicable to women over 40 who live with HIV/AIDS in the USA is limited, and the research need is broad. We propose research prioritization strategies for this population.

A pilot study was carried out in Tuscany, Italy, to provide preliminary information on the concentrations of polychlorinated dibenzodioxins (PCDDs), polychlorinated dibenzofurans (PCDFs), dioxin-like polychlorobiphenyls (DL-PCBs), and selected non-dioxin-like PCBs (NDL-PCBs) in groups of subjects living in the vicinity of two incineration plants. Seventy-four volunteers were enrolled from areas identified as under a potential impact from incinerator emissions and from not exposed areas. No significant differences were observed between subjects living in the two types of areas. Total concentrations of PCDDs, PCDFs, and DL-PCBs resulted to be in the range 23-30 pg WHO-TEQ g(-1), lipid base, for subjects in the 27-54 year age groups, while concentrations increased to 40-44 pgTEQ g(-1) for the two 55-67 year age groups. The levels of PCDDs and PCDFs were in good agreement with those observed for unexposed population groups in Italy, while the contribution to total TEQ from DL-PCBs was appreciably higher than those currently observed in the general population in Italy and other countries. As to NDL-PCBs, serum levels of the six "indicator" congeners were in the range 240-300 ng g(-1), lipid base, for subjects in the 27-54 year age groups. A raise in NDL-PCB body burden (430-470 ng g(-1), lipid base) was observed for the two 55+ year age groups, in agreement with the expected age-dependent increase. The findings from this study do not show an incremental exposure to PCDDs and PCDFs in the samples from subjects living around the two incineration plants, whereas PCB congener profiles in all samples suggest a possible impact on the area of interest of industrial activities from near industrial settlements.

Abnormalities of humoral and cell-mediated immunity have been described in Down syndrome but reported findings have been inconsistent. Confounding factors have included age, institutional versus home life, hepatitis B antigenemia, and zinc deficiency. To clarify this problem, we studied 64 children with Down syndrome (DS) compared with an age-matched control group. All children had always lived at home. All the DS children were negative for hepatitis B surface antigen. Serum zinc concentration in the DS group was on average 12 micrograms/dl lower than age-matched control children. They also had significantly lower levels of immunoglobulin M, total lymphocyte count, T and B lymphocytes, and T helper and suppressor cells. In vitro lymphocyte response to phytohemagglutinin and concanavalin A was significantly reduced at all ages in the DS group. Lymphocyte response to pokeweed mitogen increased with age in control children but decreased in the DS children. By 18 yr, the mean response for DS was 60000 cpm lower than controls. The DS group had significantly higher concentrations of immunoglobulins A and G than controls and the difference increased with age. Complement fractions C3 and C4 were also higher in the DS group at all ages. The number of HNK-1 positive cells was higher in the DS group than controls at all ages. When hepatitis and institutionalization are excluded as confounding factors, DS children still differ in both humoral and cell-mediated immunity from an age-matched control group.

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.

Little research has explored the intersection of aging and sexuality. This qualitative study is informed by a life course approach and narrative gerontology methods. Semistructured interviews were conducted with 13 women age 55 and older to explore the effects of gender, aging, and living environment on past and current sexual experiences. Subthemes from each major theme are discussed, including: (a) messages about and perceived effects of gender, (b) perceived effects of aging, and (c) perceived effects of living environment. Findings support the use of dynamical systems theory to study women's sexual experiences.

Changing the choice architecture of ageing: live different and 'catch old'.

PubMed

Gale, Deborah

2014-01-01

Physical ageing and being old are broadly feared or denied, particularly by the young (Chittister 2008: 53). The future is viewed in terms of vague, looming, disabilities, despite the fact that no one can know their personal, ageing fate. As physical and functional limitations become more apparent over time, expected validation occurs in support of the conventional narrative of decline. It is necessary to understand the traditional negative perceptions about ageing if we are to alter them. At present, they do not match the unfolding realities of what it means to grow old, in the early twenty-first century.The challenge of the new longevity is learning to navigate the unexplored life terrain between middle and extreme age. How, then, can we redefine this life stage, navigate new pathways for growing old in order to maximize the untapped contributions of the largest and longest ever living cohort? The baby boomers (born 1946-1964) are not homogenous but they are in position to become the standard bearers for a new narrative and an alternative way to live differently, while ageing.This will require changes to choice architecture and decision making about personal ageing that will challenge long held attitudes, perceptions and mindsets. Hence, changing the narrative about living long and well is the void addressed here.Life is ultimately terminal. In the interim, the process of catching old by living different is the ultimate, life enhancing skill. It is all in the choosing.

Caenorhabditis elegans (C. elegans) is a free-living nematode that has been extensively utilized as an animal model for research involving aging and neurodegenerative diseases, like Alzheimer's and Parkinson's, etc. Compared with traditional animal models, this small nematode possesses many benefits, such as small body size, short lifespan, completely sequenced genome, and more than 65% of the genes associated with human disease. All these characteristics make this organism an ideal living system for obesity and aging studies. This review gives a brief introduction of C. elegans as an animal model, highlights some advantages of research using this model and describes methods to evaluate the effect of treatments on obesity and aging of this organism.

What is the main driver of ageing in long-lived winter honeybees: antioxidant enzymes, innate immunity, or vitellogenin?

2014-06-01

To date five different theories compete in explaining the biological mechanisms of senescence or ageing in invertebrates. Physiological, genetical, and environmental mechanisms form the image of ageing in individuals and groups. Social insects, especially the honeybee Apis mellifera, present exceptional model systems to study developmentally related ageing. The extremely high phenotypic plasticity for life expectancy resulting from the female caste system provides a most useful system to study open questions with respect to ageing. Here, we used long-lived winter worker honeybees and measured transcriptional changes of 14 antioxidative enzyme, immunity, and ageing-related (insulin/insulin-like growth factor signaling pathway) genes at two time points during hibernation. Additionally, worker bees were challenged with a bacterial infection to test ageing- and infection-associated immunity changes. Gene expression levels for each group of target genes revealed that ageing had a much higher impact than the bacterial challenge, notably for immunity-related genes. Antimicrobial peptide and antioxidative enzyme genes were significantly upregulated in aged worker honeybees independent of bacterial infections. The known ageing markers vitellogenin and IlP-1 were opposed regulated with decreasing vitellogenin levels during ageing. The increased antioxidative enzyme and antimicrobial peptide gene expression may contribute to a retardation of senescence in long-lived hibernating worker honeybees. © The Author 2013.

The complexities of female aging: Four women protagonists in Penelope Lively's novels.

PubMed

Oró-Piqueras, Maricel

2016-01-01

Penelope Lively is a well-known contemporary British author who has published a good number of novels and short stories since she started her literary career in her late thirties. In her novels, Lively looks at the lives of contemporary characters moulded by specific historical as well as cultural circumstances. Four of her novels, published from 1987 to 2004, present middle-aged and older women as their main protagonists. Through the voices and thoughts of these female characters, the reader is presented with a multiplicity of realities in which women find themselves after their mid-fifties within a contemporary context. Being a woman and entering into old age is a double-sided jeopardy which has increasingly been present in contemporary fiction. Scholars such as Simone de Beauvoir (1949) and Susan Sontag (1972) were among the first to point out a "double standard of aging" when they assured that women were punished when showing external signs of aging much sooner than men. In Lively's four novels, the aging protagonists present their own stories and, through them, as well as through the voices of those around them, the reader is invited to go beyond the aging appearance of the female protagonists while challenging the limiting conceptions attached to the old body and, by extension, to the social and cultural overtones associated with old age.

However, the impact of spinal sagittal balance on locomotive syndrome and physical performance in community-living elderly has not yet been clarified. The present study investigated the influence of spinal sagittal alignment on locomotive syndrome (LS) and physical performance in community-living middle-aged and elderly women. A total of 125 women between the age of 40-88 years (mean 66.2 ± 9.7 years) who completed the questionnaires, spinal mouse test, physical examination and physical performance tests in Yakumo study were enrolled in this study. Participants answered the 25-Question Geriatric Locomotive Function Scale (GLFS-25), the visual analog scale (VAS) for low back pain (LBP), knee pain. LS was defined as having a score of >16 points on the GLFS-25. Using spinal mouse, spinal inclination angle (SIA), thoracic kyphosis angle (TKA), lumbar lordosis angle (LLA), sacral slope angle (SSA), thoracic spinal range of motion (TSROM), lumbar spinal range of motion (LSROM) were measured. Timed-up-and-go test (TUG), one-leg standing time with eyes open (OLS), and maximum stride, back muscle strength were also measured. The relationship between spinal sagittal parameters and GLFS-25, VAS and physical performance tests were analyzed. 26 people were diagnosed as LS and 99 were diagnosed as non-LS. LBP and knee pain were greater, physical performance tests were poorer, SIA were greater, LLA were smaller in LS group compared to non-LS group even after adjustment by age. SIA significantly correlated with GLFS-25, TUG, OLS and maximum stride even after adjustment by age. The cutoff value of SIA for locomotive syndrome was 6°. People with a SIA of 6° or greater were grouped as "Inclined" and people with a SIA of less than 6° were grouped as "Non-inclined". 21 people were "Inclined" and 104 were "Non-inclined".

The global increase in life expectancy is creating significant medical, social and economic challenges to current and future generations. Consequently, there is a need to identify the fundamental mechanisms underlying the ageing process. This knowledge should help develop realistic interventions capable of combatting age-related disease, and thus improving late-life health and vitality. While several mechanisms have been proposed as conserved lifespan determinants, the loss of proteostasis - where proteostasis is defined here as the maintenance of the proteome - appears highly relevant to both ageing and disease. Several studies have shown that multiple proteostatic mechanisms, including the endoplasmic reticulum (ER)-induced unfolded protein response (UPR), the ubiquitin-proteasome system (UPS) and autophagy, appear indispensable for longevity in many long-lived invertebrate mutants. Similarly, interspecific comparisons suggest that proteostasis may be an important lifespan determinant in vertebrates. Over the last 20 years a number of long-lived mouse mutants have been described, many of which carry single-gene mutations within the growth-hormone, insulin/IGF-1 or mTOR signalling pathways. However, we still do not know how these mutations act mechanistically to increase lifespan and healthspan, and accordingly whether mechanistic commonality occurs between different mutants. Recent evidence supports the premise that the successful maintenance of the proteome during ageing may be linked to the increased lifespan and healthspan of long-lived mouse mutants. © 2017 The Authors.

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.

Living arrangements are important to the elderly. However, it is common for elderly parents in urban China to not have a living situation that they consider ideal. An understanding of their preferences assists us in responding to the needs of the elderly as well as in anticipating future long-term care demands. The aim of this study is to provide a clear understanding of preferences for future living arrangements and their associated factors among middle-aged and older people in urban China. Data were extracted from the CHARLS 2011-2012 national baseline survey of middle-aged and elderly people. In the 2011 wave of the CHARLS, a total of 17,708 individual participants (10,069 main respondents and 7,638 spouses) were interviewed; 2509 of the main respondents lived in urban areas. In this group, 41 people who were younger than 45 years old and 162 who had missing data in the variable "living arrangement preference" were excluded. Additionally, 42 people were excluded because they chose "other" for the variable "living arrangement preference" (which was a choice with no specific answer). Finally, a total of 2264 participants were included in our study. The most popular preference for future living arrangements was living close to their children in the same community/neighborhoods, followed by living with adult children. The degree of community handicapped access, number of surviving children, age, marital status, access to community-based elderly care centers and number of years lived in the same community were significantly associated with the preferences for future living arrangements among the respondents. There is a trend towards preference for living near adult children in urban China. Additionally, age has a positive effect on preference for living close to their children. Considerations should be made in housing design and urban community development plans to fulfill older adults' expectations. In addition, increasing the accessibility of public facilities in

We test the 'free radical theory of aging' using six species of colubrid snakes (numerous, widely distributed, non-venomous snakes of the family Colubridae) that exhibit long (> 15 years) or short (< 10 years) lifespans. Because the 'rate of living theory' predicts metabolic rates to be correlated with rates of aging and oxidative damage results from normal metabolic processes we sought to answer whether physiological parameters and locomotor performance (which is a good predictor of survival in juvenile snakes) mirrored the evolution of lifespans in these colubrid snakes. We measured whole animal metabolic rate (oxygen consumption Vo2), locomotor performance, cellular metabolic rate (mitochondrial oxygen consumption), and oxidative stress potential (hydrogen peroxide production by mitochondria). Longer-lived colubrid snakes have greater locomotor performance and reduced hydrogen peroxide production than short-lived species, while whole animal metabolic rates and mitochondrial efficiency did not differ with lifespan. We present the first measures testing the 'free radical theory of aging' using reptilian species as model organisms. Using reptiles with different lifespans as model organisms should provide greater insight into mechanisms of aging.

Past studies have shown that living alone is detrimental to older adults' mental health. However, there has been little focus on how older adults' psychological distress differed by more detailed living arrangement, as well as by gender. The present study investigates various living arrangements in association with psychological distress among older men and women. Data from community-dwelling Japanese older adults were collected through a mail survey (n = 1,807, aged 65-74 years, 51.5 % men). Psychological distress level was measured using Kessler's six-item psychological distress scale. Living arrangements were categorized into four groups; "living with spouse only", "living with spouse and other family", "living with other family without spouse" or "living alone". Multiple logistic regression analyses were used to examine the associations of living arrangements with psychological distress level. Older adults living alone were observed to have higher psychological distress. In addition, gender-stratified analyses showed that higher distress levels were observed among older men living with family, but without a spouse (OR: 2.85, 95 % CI: 1.51-5.39). In contrast, higher distress was observed among older women living with spouse and other family (OR: 1.53, 95 % CI: 1.03-2.28). Psychological distress in older Japanese adults was associated with living arrangements, but such associations differed by gender. The association of living with a spouse on older men's mental health was striking, while living with any family was found to be rather important for older women, aged 65-74 years.

Who Lives Alone During Old Age? Trends in the Social and Functional Disadvantages of Sweden's Solitary Living Older Adults.

This study identifies specific social and functional disadvantages associated with living alone during old age in Sweden and assesses whether these associations have changed during recent decades. Data came from repeated cross-sectional surveys of Swedish adults aged 77+ during 1992-2014. Findings indicate that several types of disadvantage are consistently associated with the probability of living alone including financial insecurity and having never married for women and having never married and mobility impairment for men. Also for older men, low education has become an increasing strong determinant of living alone. These findings suggest that older adults who live alone are a subgroup that is particularly, and in some cases increasingly, vulnerable with respect to social and functional status. This has important policy implications related to addressing the needs of this growing subgroup as well as methodological implications for studies on the health effects of living alone.

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

To investigate which clinical characteristics will influence the pregnancy rate and live birth rate after myomectomy. Data of clinical characteristics and reproductive outcome from 471 patients who wished to conceive and who underwent abdominal or laparoscopic myomectomy in the Obstetrics and Gynecology Hospital of Fudan University from January 2008 to June 2012 were retrospectively analyzed. Average age in the pregnancy group (30.0±3.7 years) and the nonpregnancy group (31.2±4.1 years) was statistically different (P=.000). The diameter of the biggest myoma had a positive relationship with the pregnancy rate when it was <10 cm (rs=0.095, P=.039). Abortions before myomectomy, operation type, number, location, and classification of myomas, uterine cavity penetration, and uterine volume seemed not to influence the pregnancy rate (P>.05). The location of the myoma may influence the live birth rate after myomectomy (rs=0.198, P=.002). Anterior and posterior myomas were associated with higher live birth rates than other locations (P=.001). The average interval between myomectomy and pregnancy was 16.0±8.7 months, and there was no difference between the abdominal (17.2±8.6 months) and laparoscopic (15.2±8.8 months) groups (P=.102). The interval in the live birth group was 15.0±8.4 months, and that in the non-live birth group was 18.9±9.3 months; the difference was significant (P=.005). Patients' age, myoma size and location, and interval between myomectomy and pregnancy may influence the pregnancy rate and live birth rate after myomectomy.

Women are living with HIV into middle and older age and are likely to face multiple comorbidities and stressors as they age. This study focused on understanding how women who experience multiple forms of oppression and ongoing adversity are still able to adapt and stand strong. Using a theoretical framework of resilience and a feminist research ideology, interviews of eight middle-aged and older African American women living with HIV were analyzed. Despite experiences of HIV-related discrimination, trauma, and violence, these women demonstrated a remarkable ability to adapt and maintain support. Implications for research and practice are discussed.

Peru is experiencing a stage of nutritional transition where the principal characteristics are typical of countries undergoing development. The objectives of this study were the following: (a) compare physical growth patterns with an international standard; (b) determine biological age; and (c) analyze the double nutritional burden of adolescents living at a moderate altitude in Peru. Weight, standing height, and sitting height were measured in 551 adolescents of both sexes (12.0 to 17.9 years old) from an urban area of Arequipa, Peru (2328 m). Physical growth was compared with the international standard of the CDC-2000. Biological age was determined by using a non-invasive transversal technique based on years from age at peak height velocity (APHV). Nutritional state was determined by means of weight for age and height for age. Z scores were calculated using international standards from the CDC-2000. Body weight for both sexes was similar to the CDC-2000 international standards. At all ages, the girls' height (p < 0.05) was below the standards. However, the boys' height (p < 0.05) was less at ages, 15, 16, and 17. Biological age showed up in girls at age 12.7 years and for boys at 15.2 years. Stunted growth (8.7% boys and 18.0% girls) and over weight (11.3% boys and 8.8% girls) occurred in both groups. A relationship existed in both sexes between the categories of weight for the age and stunted growth by sex. Adolescents living at a moderate altitude exhibited stunted linear growth and biological maturation. Furthermore, adolescents of both sexes showed the presence of the double nutritional burden (stunted growth and excessive weight).

BACKGROUND: The changing racial and ethnic diversity of the U.S. population along with delayed childbearing suggest that shifts in the demographic composition of gravidas are likely. It is unclear whether trends in the proportion of births to parous women in the United States have changed over the decades by race and ethnicity, reflecting parallel changes in population demographics. METHODS: Singleton deliveries > or = 20 weeks of gestation in the United States from 1989 through 2000 were analyzed using data from the "Natality data files" assembled by the National Center for Health Statistics (NCHS). We classified maternal age into three categories; younger mothers (aged < 30 years), mature mothers (30-39 years) and older mothers (> or = 40 years) and maternal race/ethnicity into three groups: blacks (non-Hispanic), Hispanics and whites (non-Hispanic). We computed birth rates by period of delivery across the entire population and repeated the analysis stratified by age and maternal race. Chi-squared statistics for linear trend were utilized to assess linear trend across three four-year phases: 1989-1992, 1993-1996 and 1997-2000. In estimating the association between race/ethnicity and parity status, the direct method of standardization was employed to adjust for maternal age. RESULTS: Over the study period, the total number of births to blacks and whites diminished consistently (p for trend < 0.001), whereas among Hispanics a progressive increase in the total number of deliveries was evident (p for trend < 0.001). Black and white women experienced a reduction in total deliveries equivalent to 10% and 9.3%, respectively, while Hispanic women showed a substantial increment in total births (25%). Regardless of race or ethnicity, birth rate was associated with increase in maternal age in a dose-effect fashion among the high (5-9 previous live births), very high (10-14 previous live births) and extremely high (> or = 15 previous live births) parity groups (p for trend

The influence of living conditions in early life on life satisfaction in old age.

2013-03-01

This article examines the influence of living conditions in early life on life satisfaction in old age in eleven Western European countries. It combines the influence of individual conditions, for example housing and family background, with country characteristics in the decade of birth. Using pooled data from the second and third wave of the Survey of Health, Ageing and Retirement in Europe, multilevel models show that early life living conditions have an influence on life satisfaction in old age. Furthermore, interaction effects between current and past living conditions show that adverse living conditions strengthen the effect of early life on life satisfaction in later life and therefore are an indication of cumulative inequality over the life course.

Very few studies were devoted to permanent effects of nocturnal railway noise on sleep and cardiovascular reactivity. We investigated the effects of nocturnal railway noise on sleep and cardiovascular response in young and middle-aged adults living for many years either near a railway track or in a quiet area. Forty subjects (50% males) divided into two age groups (juniors: 26.2+/-3.6 and seniors: 56.2+/-4.2) participated in this experiment. Half of them lived near a railway track (RW group: 2.6 to 19 years) and the other half in a quiet environment (QE group: 8.1 to 14.2 years). After an adaptation night, all subjects underwent two nights in the laboratory: one control night and one noisy night (30 by-passes of a freight train). Sleep and cardiovascular modifications were assessed in response to noise. Sleep fragmentation indices were lower in RW subjects compared to QE whatever their age. In response to noise, there was a higher cardiovascular response rate to noise in RW juniors and a lower cardiovascular response rate in RW seniors compared to their age-paired QE counterparts. In conclusion, permanent exposure to nocturnal railway noise leads to decreased sleep fragmentation and to cardiovascular habituation. It is suggested that during the initial period experienced by residents living near railway tracks, nocturnal railway noise could induce a sensitization process on the autonomic response to noise reflecting a startle/defense reflex due to its functional significance, which progressively turns to habituation in the long-term if no adverse effect is experienced.

Living kidney donor candidates accept a range of risks and benefits when they decide to proceed with nephrectomy. Informed consent around this decision assumes they receive reliable data about outcomes they regard as critical to their decision making. We identified the outcomes most important to living kidney donors and described the reasons for their choices. Previous donors were purposively sampled from three transplant units in Australia (Sydney and Melbourne) and Canada (Vancouver). In focus groups using the nominal group technique, participants identified outcomes of donation, ranked them in order of importance, and discussed the reasons for their preferences. An importance score was calculated for each outcome. Qualitative data were analyzed thematically. Across 14 groups, 123 donors aged 27-78 years identified 35 outcomes. Across all participants, the ten highest ranked outcomes were kidney function (importance=0.40, scale 0-1), time to recovery (0.27), surgical complications (0.24), effect on family (0.22), donor-recipient relationship (0.21), life satisfaction (0.18), lifestyle restrictions (0.18), kidney failure (0.14), mortality (0.13), and acute pain/discomfort (0.12). Kidney function and kidney failure were more important to Canadian participants, compared with Australian donors. The themes identified included worthwhile sacrifice, insignificance of risks and harms, confidence and empowerment, unfulfilled expectations, and heightened susceptibility. Living kidney donors prioritized a range of outcomes, with the most important being kidney health and the surgical, lifestyle, functional, and psychosocial effects of donation. Donors also valued improvements to their family life and donor-recipient relationship. There were clear regional differences in the rankings. Copyright © 2018 by the American Society of Nephrology.

Orphans and vulnerable youth who live in group homes are at risk of poor mental health and sexual and drug-using behaviors that increase the risk of HIV transmission. This study explores factors related to this risk among youth living in group homes ("children's homes") for orphans and vulnerable children in South Africa, a country afflicted by high levels of parental loss due to HIV. The study explores 1) knowledge and attitudes about HIV, 2) social support, 3) communication with group home caregivers, and 4) the relevance of an existing evidence-based HIV prevention and mental health promotion program to situations where sexual and drug risk behaviors can occur. In-depth qualitative individual interviews were conducted with 20 youth (age 10 to 16 years) residing in two children's homes in Durban, South Africa. Content analysis focused on critical themes related to coping and prevention of risk activities. Respondents exhibited inconsistent and incomplete knowledge of HIV transmission and prevention. They displayed positive attitudes toward people living with HIV, but reported experiencing or witnessing HIV-related stigma. Participants witnessed substance use and romantic/sexual relationships among their peers; few admitted to their own involvement. While relationships with childcare workers were central to their lives, youth reported communication barriers related to substance use, sex, HIV, and personal history (including parental loss, abuse, and other trauma). In conclusion, these qualitative data suggest that evidence-based HIV prevention programs that bring caregivers and youth together to improve communication, HIV knowledge, social support, youth self-esteem, and health care, reduce sexual and drug risk behaviors, and strengthen skills related to negotiating situations of sexual and substance use possibility could benefit youth and childcare workers in children's homes.

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.

Living fast, dying when? The link between aging and energetics.

PubMed

Speakman, John R; Selman, Colin; McLaren, Jane S; Harper, E Jean

2002-06-01

The idea that aging should be linked to energy expenditure has a long history that can be traced to the late 1800s and the industrial revolution. Machines that are run fast wear out more quickly, so the notion was born that humans and animals might experience similar fates: the faster they live (expressed as greater energy expenditure), the sooner they die. Evidence supporting the "rate-of-living" theory was gleaned from the scaling of resting metabolism and life span as functions of body mass. The product of these factors yields a mass-invariant term, equivalent to the "amount of living." There are at least four problems with this evidence, which are summarized and reviewed in this communication: 1) life span is a poor measure of aging, 2) resting metabolism is a poor measure of energy expenditure, 3) the effects are confounded by body mass and 4) the comparisons made are not phylogenetically independent. We demonstrate that there is a poor association between resting metabolic rate (RMR) and daily energy expenditure (DEE) measured using the doubly labeled water (DLW) method at the level of species. Nevertheless, the scaling relation between DEE and body mass still has the same scaling exponent as the RMR and body mass relationship. Thus, if we use DEE rather than RMR in the analysis, the rate-of-living ideas are still supported. Data for 13 species of small mammal were obtained, where energy demands by DLW and longevity were reliably known. In these species, there was a strong negative relationship between residual longevity and residual DEE, both with the effects of body mass removed (r(2) = 0.763, F = 32.1, P < 0.001). Hence, the association of energy demands and life span is not attributed to the confounding effects of body size. We subjected these latter data to an analysis that extracts phylogenetically independent contrasts, and the relationship remained significant (r(2) = 0.815, F = 39.74, P < 0.001). Small mammals that live fast really do die young

Gender Disparity in Living-Donor Kidney Transplant Among Minority Ethnic Groups.

We have limited data on gender disparities between living kidney transplant donors and recipients across ethnic groups. This was a retrospective cohort study of all living-donor kidney transplants performed at a single center in an ethnically diverse region of England. Data were extracted from the United Kingdom National Transplant Database and University Hospitals Birmingham electronic medical records. We analyzed 713 living-donor kidney transplant procedures that were performed from 1987 to 2014. Gender disparities were observed, with women more likely to be living donors (54.7%) and less likely to be recipients (39.4%). Most male recipients received kidneys from female donors versus male donors (70.2% vs 29.8%), whereas the proportion of men receiving kidneys from women (50.9%) and from men (49.1%) were similar (P < .001). Black, Asian, and donors from other minority groups comprised 18.7% of the donor cohort. South Asian partner-to-partner transplants (n = 22) were predominantly men receiving transplants from women (90.9%) versus women receiving transplants from men (9.1%; P = .003). Male patients more commonly donated their kidney to children than to women (10.2% vs 6.4%; P = .046). South Asian donations to children were similar between males and females; however, boys exclusively received kidneys from male donors (8/8) versus from female donors (8/12). Gender disparity exists in living-donor kidney transplant, with disparities more pronounced in some ethnic groups and among particular relationships. This finding requires targeted counseling and research to understand whether the cause is medical or sociocultural obstacles.

Background: Peru is experiencing a stage of nutritional transition where the principal characteristics are typical of countries undergoing development. Objectives: The objectives of this study were the following: (a) compare physical growth patterns with an international standard; (b) determine biological age; and (c) analyze the double nutritional burden of adolescents living at a moderate altitude in Peru. Design: Weight, standing height, and sitting height were measured in 551 adolescents of both sexes (12.0 to 17.9 years old) from an urban area of Arequipa, Peru (2328 m). Physical growth was compared with the international standard of the CDC-2000. Biological age was determined by using a non-invasive transversal technique based on years from age at peak height velocity (APHV). Nutritional state was determined by means of weight for age and height for age. Z scores were calculated using international standards from the CDC-2000. Results: Body weight for both sexes was similar to the CDC-2000 international standards. At all ages, the girls’ height (p < 0.05) was below the standards. However, the boys’ height (p < 0.05) was less at ages, 15, 16, and 17. Biological age showed up in girls at age 12.7 years and for boys at 15.2 years. Stunted growth (8.7% boys and 18.0% girls) and over weight (11.3% boys and 8.8% girls) occurred in both groups. A relationship existed in both sexes between the categories of weight for the age and stunted growth by sex. Conclusions: Adolescents living at a moderate altitude exhibited stunted linear growth and biological maturation. Furthermore, adolescents of both sexes showed the presence of the double nutritional burden (stunted growth and excessive weight). PMID:26404334

Ten new and emerging trends in residential group living environments.

2009-01-01

Residential styled environments for physically challenged people with neuro disabilities are rapidly replacing the standard institutional skilled nursing home. Ten trends are described that utilize residential design approaches to the physical environment while relying on home-care style methods for service delivery. Combined these two forces create powerful differentiators which make group residential settings more friendly and humane. Northern European, as well as, US best practices and prototypes are described that combine housing with services in a range of contexts. The success of northern Europeans in promulgating models of aging-in-place that keep those at risk more independent in the community or within family settings are remarkable. Topics like the impact of small group living clusters, interior design treatments, access to landscape gardens, life skill management methods, movement systems for circulation and exercise, shared space priorities, unit design trends and innovative care giving techniques are introduced. The focus of the article is on specific practices gleaned from cultures and exemplars that appear to increase autonomy, independence and privacy for those who are threatened because of their disabilities with the loss of these lifestyle attributes. Promising concepts of service organization and community outreach are combined with detailed recommendations that address the need for lift technology and safety features in bathrooms and kitchens.

Recent studies report that the majority of older adults wish to live in their own homes, for as long as possible. This creates a growing interest in technologies to enable older people to remain living independently at home. The purpose of this article is to provide a narrative review of current technology appropriate for older adults' home use. The key research questions were as follow: 1- What is the evidence demonstrating that gerontechnologies are effective in enabling independent living? 2- What are devices designed specifically for frail elderly persons ? Several publications were identified about devices targeting social isolation (videophonic communication, affective orthotic devices or companion-type robots, personal emergency response systems [security]), autonomy loss (technologies for maintenance of autonomy in the activities of daily living) and cognitive disorders (cognitive orthotics, wandering management systems, telemonitoring). Very few articles dealt specifically with the frail older person. In particular, there was extremely limited evidence on use and efficacy of these devices within this population. There is a need to obtain a consensus on definition of the technologies, and also to revisit work strategies and develop innovative business models. To meet this goal, we need to create a network of technological companies, aging services organizations, end-users, academics, and government representatives to explore the real needs of the frail older population and to develop and validate new devices promoting aging at home.

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.

Vespertilionid bats (Mammalia: Order Chiroptera) live 3–10 times longer than other mammals of an equivalent body size. At present, nothing is known of how bat fecal metabolic profiles shift with age in any taxa. This study established the feasibility of using a non-invasive, fecal metabolomics approach to examine age-related differences in the fecal metabolome of young and elderly adult big brown bats (Eptesicus fuscus) as an initial investigation into using metabolomics for age determination. Samples were collected from captive, known-aged big brown bats (Eptesicus fuscus) from 1 to over 14 years of age: these two ages represent age groups separated by approximately 75% of the known natural lifespan of this taxon. Results showed 41 metabolites differentiated young (n = 22) and elderly (n = 6) Eptesicus. Significant differences in metabolites between young and elderly bats were associated with tryptophan metabolism and incomplete protein digestion. Results support further exploration of the physiological mechanisms bats employ to achieve exceptional longevity. PMID:29715267

Relations of Early Motor Skills on Age and Socialization, Communication, and Daily Living in Young Children With Developmental Disabilities.

Young children with developmental disabilities experience known deficits in salient child behaviors, such as social behaviors, communication, and aspects of daily living, behaviors that generally improve with chronological age. The purpose of this study was to examine the mediating effects of motor skills on relations of age and salient child behaviors in a group of young children with developmental disabilities, thus tapping into the potential influences of motor skills in the development of salient child behaviors. One hundred thirteen young children with developmental disabilities participated in this study. Independent mediation analysis, with gender as a moderator between the mediating and outcome variable, indicated that motor skills meditated relations between age and socialization, communication, and daily living skills in young male children with developmental disabilities, but not female participants. Findings suggest motor skill content needs to be considered in combination with other child behaviors commonly focused on in early intervention.

Objective To estimate age-specific probabilities of live-birth with oocyte cryopreservation in non-donor (ND) egg cycles. Design Individual patient data (IPD) meta-analysis. Setting Assisted reproduction centers. Patients Infertile patients undergoing ND mature oocyte cryopreservation. Interventions PubMed was searched for the clinical studies on oocyte cryopreservation from January 1996 through July 2011. Randomized and non-randomized studies that used ND frozen-thawed mature oocytes with pregnancy outcomes were included. Authors of eligible studies were contacted to obtain IPD. Main outcome measures Live-birth probabilities based on age, cryopreservation method, and the number of oocytes thawed, injected, or embryos transferred. Results Original data from 10 studies including 2265 cycles from 1805 patients were obtained. Live-birth success rates declined with age regardless of the freezing technique. Despite this age-induced compromise, live-births continued to occur as late as to the ages of 42 and 44 with slowly-frozen (SF) and vitrified (VF) oocytes, respectively. Estimated probabilities of live-birth for VF oocytes were higher than those for SF. Conclusions The live-birth probabilities we calculated would enable more accurate counseling and informed decision of infertile women who consider oocyte cryopreservation. Given the success probabilities, we suggest that policy-makers should consider oocyte freezing as an integral part of prevention and treatment of infertility. PMID:23706339

The Wallpaper Effect: The Contact Hypothesis Fails for Minority Group Members Who Live in Areas with a High Proportion of Majority Group Members

We aim to provide one explanation for why the link between contact and prejudice is consistently less strong for minority group members than it is for majority group members. Specifically, we propose a “wallpaper effect” such that contact works to increase minority group members' positivity towards majority groups when they live in areas densely populated with other minority group members. Conversely, we suggest that when minority group members live in neighborhoods patterned with majority group faces (as is so often the case), contact will be less transformative. We test this assumption using a large sample of both New Zealander minority (Māori; N = 925) and majority (European; N = 3805) group members. In line with predictions, Māori who lived in minority dense neighborhoods showed the traditional association between contact and increased warmth towards New Zealander Europeans. This relationship, however, was weak or non-existent when they lived in primarily European neighborhoods. Contact effects in majority group members were unaffected by neighborhood composition. The interaction held when controlling for, and was not explained by: gender, income, experiences of harm, cognitions of race-based rejection, or realistic threat. We provide the first evidence to suggest that when it comes to minority group members' intergroup attitudes, contact with majority group members may be a relatively ineffective predictor unless the “wallpaper” of their lives is minority-dense.

Depression is one the most common mental disorders in prisons. People living with HIV are more likely to develop psychological difficulties when compared with the general population. This study aims to determine the efficacy of cognitive group therapy based on schema-focused approach in reducing depression in prisoners living with HIV. The design of this study was between-groups (or "independent measures"). It was conducted with pretest, posttest, and waiting list control group. The research population comprised all prisoners living with HIV in a men's prison in Iran. Based on voluntary desire, screening, and inclusion criteria, 42 prisoners living with HIV participated in this study. They were randomly assigned to an experimental group (21 prisoners) and waiting list control group (21 prisoners). The experimental group received 11 sessions of schema-focused cognitive group therapy, while the waiting list control group received the treatment after the completion of the study. The various groups were evaluated in terms of depression. ANCOVA models were employed to test the study hypotheses. Collated results indicated that depression was reduced among prisoners in the experimental group. Schema therapy (ST) could reduce depression among prisoners living with HIV/AIDS.

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

PubMed

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.

Reciprocity in group-living animals: partner control versus partner choice.

PubMed

Schino, Gabriele; Aureli, Filippo

2017-05-01

Reciprocity is probably the most debated of the evolutionary explanations for cooperation. Part of the confusion surrounding this debate stems from a failure to note that two different processes can result in reciprocity: partner control and partner choice. We suggest that the common observation that group-living animals direct their cooperative behaviours preferentially to those individuals from which they receive most cooperation is to be interpreted as the result of the sum of the two separate processes of partner control and partner choice. We review evidence that partner choice is the prevalent process in primates and propose explanations for this pattern. We make predictions that highlight the need for studies that separate the effects of partner control and partner choice in a broader variety of group-living taxa. © 2016 Cambridge Philosophical Society.

CancerChatCanada is a pan-Canadian initiative with a mandate to make professionally led cancer support groups available to more people in Canada. Although online support groups are becoming increasingly popular, little is known about therapist-led, synchronous groups using live chat. The purpose of this study was to generate a rich descriptive account of communication experiences in CancerChatCanada groups and to gain an understanding of processes associated with previously-reported benefits. We used interpretive description to analyze interview segments from 102 patients, survivors and family caregivers who participated in CancerChatCanada groups between 2007 and 2011. The analysis yielded four inter-related process themes (Reaching Out From Home, Feeling Safe, Emotional Release, and Talking With Text) and one outcome theme (Resonance and Kinship). The findings extend previous research about text-only online support groups and provide novel insights into features of facilitated, live chat communication that are valued by group members.

2015-01-01

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

Long-lived nuclear spin states have a relaxation time much longer than the longitudinal relaxation time T1. Long-lived states extend significantly the time scales that may be probed with magnetic resonance, with possible applications to transport and binding studies, and to hyperpolarised imaging. Rapidly rotating methyl groups in solution may support a long-lived state, consisting of a population imbalance between states of different spin exchange symmetries. Here, we expand the formalism for describing the behaviour of long-lived nuclear spin states in methyl groups, with special attention to the hyperpolarisation effects observed in (13)CH3 groups upon rapidly converting a material with low-barrier methyl rotation from the cryogenic solid state to a room-temperature solution [M. Icker and S. Berger, J. Magn. Reson. 219, 1 (2012)]. We analyse the relaxation properties of methyl long-lived states using semi-classical relaxation theory. Numerical simulations are supplemented with a spherical-tensor analysis, which captures the essential properties of methyl long-lived states.

2009-06-01

The majority of community-dwelling people 60 years and older are independent and live actively. However, there is little information about elderly persons' views on aging, health and health promotion. Therefore, an anonymous, written questionnaire survey was performed in a representative sample of inhabitants from a section of the city of Hamburg, 60 years and older; 5 year intervals, 14 subsamples according to 7 age groups of females and males. Questionnaires from 950 participants (29% response) could be evaluated: mean age 71.5 years, 58% women, 34% living alone, 5% with professional healthcare needs as indicated by status according to German nursing care insurance. Senior citizens' positive attitudes towards aging and health were predominant: 69% of respondents felt young, 85% worried about loss of autonomy in old age. The results provide evidence indicating potential for improving health-promoting lifestyles in parts of the older population by evaluating and strengthening older persons' competencies and by considering their concerns seriously. These results provide valuable information for future plans in the public-health sector in the city of Hamburg where particular health-promoting actions for elderly persons will be considered.

Long-lived nuclear spin states in rapidly rotating CH2D groups

Although monodeuterated methyl groups support proton long-lived states, hindering of the methyl rotation limits the singlet relaxation time. We demonstrate an experimental case in which the rapid rotation of the CH2D group extends the singlet lifetime but does not quench the chemical shift difference between the CH2D protons, induced by the chiral environment. Proton singlet order is accessed using Spin-Lock Induced Crossing (SLIC) experiments, showing that the singlet relaxation time TS is over 2 min, exceeding the longitudinal relaxation time T1 by a factor of more than 10. This result shows that proton singlet states may be accessible and long-lived in rapidly rotating CH2D groups.

Living With Diabetes in Appalachia: A Focus Group Study.

PubMed

Carpenter, Roger; Smith, Mary Jane

This article presents an innovative holistic practice application based on evidence from a focus group study on managing diabetes. The purpose of this study addressed the research question: How do persons with type 2 diabetes describe ways of managing the challenge of living with diabetes? A second purpose was to link the findings on ways to manage diabetes to holistic nursing practice through story theory. Nine adults with type 2 diabetes living in rural West Virginia participated in 3 focus groups. Using content analysis, the study findings integrated themes with core qualities, and are as follows: living life as an evolving process is awakening to the present and doing it your way, being on guard is a vigilant ongoing responsibility, attending to bodily experience is awareness of body and facing life stress, and knowing the consequences is awareness of potential problems and taking charge. Merging the study findings with the concepts of story theory led to the development of an innovative practice application for managing diabetes. Managing diabetes in this practice application goes beyond problem-centeredness to a patient-centered approach, offering attention to individual preferences. Since managing diabetes is a major problem in Appalachia, there a need for innovative approaches. This study adds to the body of knowledge on how persons from Appalachia manage diabetes. In addition, it offers a story practice approach for managing diabetes-replacing a problem focus to a more holistic approach to practice leading to more meaningful and fulfilling outcomes.

Mature female sperm whales (Physeter macrocephalus) live in socially cohesive groups of 10-30, which include immature animals of both sexes, and within which there is communal care of the young. We examined kinship in such groups using analyses of microsatellite DNA, mitochondrial DNA sequence, and sex-linked markers on samples of sloughed skin collected noninvasively from animals in three groups off the coast of Ecuador. Social groups were defined through photographic identification of individuals. Each group contained about 26 members, mostly female (79%). Relatedness was greater within groups, as compared to between groups. Particular mitochondrial haplotypes were characteristic of groups, but all groups contained more than one haplotype. The data are generally consistent with each group being comprised of several matrillines from which males disperse at about the age of 6 years. There are indications of paternal relatedness among grouped individuals with different mitochondrial haplotypes, suggesting long-term associations between different matrilines.

Kallery, Maria; Loupidou, Thomais

2016-06-01

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

This study examined the influence of walkability on walking behaviour and assessed whether associations varied according to life-stage and population center (PC) size. Walkability scores were obtained for the six-digit postal codes of residential neighbourhoods of 11,200 Canadians, who participated in biennial assessments of the National Population Health Survey from 1994 to 2010. Participants were stratified by age-group. Mixed-effects logistic regression models were used to estimate the influence of cumulative exposure to neighborhood walkability on utilitarian and exercise walking by PC size and life-stage. Associations of neighbourhood walkability with utilitarian and exercise walking varied according to age-group and PC size. Exposure to high walkable neighborhoods was associated with utilitarian walking in younger and older adults in all PC sizes, except for older adults living in a medium PC. Living in a highly walkable neighborhood in a large PC was associated with walking for exercise in younger (OR: 1.42; 95%CI: 1.20-1.67) and older adults (OR: 2.09; 95%CI: 1.51-2.89). Living in highly walkable neighbourhood in a medium PC was associated with walking for exercise in older adults (OR: 1.62; 95%CI: 1.15-2.29). These results emphasize the need to consider the size and nature of every community, and the age-group of a population when implementing strategies to promote walking.

Knowledge of the human visual system helps to develop better computational models of visual attention. State-of-the-art models have been developed to mimic the visual attention system of young adults that, however, largely ignore the variations that occur with age. In this paper, we investigated how visual scene processing changes with age and we propose an age-adapted framework that helps to develop a computational model that can predict saliency across different age groups. Our analysis uncovers how the explorativeness of an observer varies with age, how well saliency maps of an age group agree with fixation points of observers from the same or different age groups, and how age influences the center bias tendency. We analyzed the eye movement behavior of 82 observers belonging to four age groups while they explored visual scenes. Explorative- ness was quantified in terms of the entropy of a saliency map, and area under the curve (AUC) metrics was used to quantify the agreement analysis and the center bias tendency. Analysis results were used to develop age adapted saliency models. Our results suggest that the proposed age-adapted saliency model outperforms existing saliency models in predicting the regions of interest across age groups.

Redefining meaningful age groups in the context of disease.

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.

To compare physical activity (PA) measured by 4 methods in adults under free-living conditions in relation to selected demographic and anthropometric variables. Cohort study. Department of Sports Medicine. Clinically healthy men (81) and women (69) aged 45 to 64 years. Physical activity monitoring for 7 consecutive days under free-living conditions by pedometer (P) and accelerometer (A) simultaneously and PA questionnaires: International Physical Activity Questionnaire (IPAQ) and Seven-Day Physical Activity Questionnaire Recall (SDPAR) completed after the 7-day PA. Comparison of PA measured by pedometer, IPAQ, and SDPAR with accelerometer with regard to age, body mass, gender, and obesity type. Total energy expenditure (EE) by IPAQ was higher than A (P < 0.001) in both groups regardless of age, body mass, or obesity type. Mean EE value by P was greater than A (P < 0.001) in central-obesity males and lower than A (P < 0.001) in central-obesity females. There were differences in step counts in women, unnoticed in men. SDPAR overestimated total EE in gynoid-obesity males and in central-obesity females compared with A. Ninety-five percent CI was the largest around IPAQ compared with P and SDPAR, with SDPAR showing the best agreement with A. Body mass and obesity type influenced PA measurements. To monitor PA, it is recommended to use pedometer in normal bodyweight and overweight groups while accelerometer is advisable in obese subjects. A combined approach of objective and subjective PA monitoring tools is preferable.

Live birth rates by age of mother and total fertility rates by urban and rural areas in Japan are generally decreasing. Japanese women ages 15-49 were studied. Graphs presenting fertility rates according to age in 1975 and 1980 in urban and rural areas show that fertility rates are considerably higher in rural areas than in urban centers (by as much as 20% for the 25-29 age group). In a table showing urban/rural total fertility rates and distributions among prefectures in 1975 and 1980, the prefecture with the highest total fertility rate (2.88495 in 1975 and 2.37804 in 1980) is Okinawa and the lowest total fertility rate is found in Tokyo (1.62287 in 1975 and 1.43693 in 1980). The average total fertility rate in 1980 was 1.82849; in urban centers it was 1.78919 and rural areas, 1.92105. Finally, a comparison of total fertility rates by urban and rural areas and by age shows that in 1975 the rural fertility rate was .16 higher than that of urban areas, and that in 1980 all fertility rates (total, urban, and rural) were lower, with the rural fertility rate decreasing at the same rate as did the urban fertility rate in 1975. It is interesting to note that between 1975-1980 birth rates have been decreasing in both urban and rural areas in all age groups except for the 30-34 year old group which in urban centers was higher in 1980 than in rural areas. This can be attributed to the recent trend among Japanese women of delaying childbirth.

Although many studies have suggested social participation (SP) has beneficial effects on elderly people's health, most of them failed to deal with paid work. Additionally, few studies have focused on the age effect between SP and older people's health. To investigate whether the association between SP, including paid work, and instrumental activities of daily living (IADL), exhibits not only in gender, but also in age among community-dwelling older adults. In 2014, we distributed self-administered questionnaires to all community-dwelling elderly aged ≥65 in two medium-sized cities in Nara Prefecture, Japan (n = 32,825). 22,845 residents submitted the questionnaire (response rate, 69.6%). Analyzed subjects were limited to 17,680 persons who had neither dependency in basic ADL nor missing data for required items. SP was assessed based on participation frequency in seven types of social activities: volunteer groups, sports groups, hobby groups, cultural groups, senior citizens' clubs, neighborhood community associations, and paid work. Using Poisson regression models, prevalence ratio for poor IADL was calculated. To examine age and gender differences in the association between SP and IADL, we performed stratified analyses by age and gender group; male young-old (aged 65-74), male old-old (aged ≥75), female young-old, and female old-old. Prevalence of those with poor IADL was 17.1% in males and 4.5% in females, showing a significant gender difference. After adjustment for relevant covariates, volunteer groups were inversely associated with poor IADL only in males and the relationship was stronger in the old-old group than in the young-old group. Conversely, only females had a significant inverse association between paid work and poor IADL, and the association was not reliant on their ages but only those who participated infrequently had a favorable effect. Influence of age in the beneficial association between SP and IADL was generally larger in the old

The present study reports findings from a study of preschool-age Inuit children living in the Arctic regions of Canada and Greenland. We compare stature and obesity measures using cutoffs from the Centers for Disease Control and the International Obesity Task Force references. The sample is comprised of 1121 Inuit children (554 boys and 567 girls) aged 3-5 years living in Nunavut (n=376) and Nunavik (n=87), Canada, in the capital city of Nuuk, Greenland (n=86), and in Greenland's remaining towns and villages (n=572). Greenland Inuit children were significantly taller than their Canadian counterparts, with greatest height and weight observed among children from Nuuk. Overall prevalence of stunting was low with the three cutoffs yielding similar values for height-for-age z-scores. Obesity prevalence was higher among Canadian Inuit children than their Greenland counterparts. Inuit children have stature values consistent with those of the Centers for Disease Control reference and low prevalence of stunting, though geographic variability in mean stature values between Canadian and Greenlandic samples likely reflects differences in both socioeconomic status and genetic admixture. Obesity prevalence is high among both Canadian and Greenland Inuit preschoolers, with children living in the city of Nuuk exhibiting lower obesity prevalence than children living in either Nunavut or Nunavik, Canada or Greenland's towns and villages. Varying obesity prevalence may reflect varying degrees of food security in remote locations as well as the influence of stature and sitting height which have not been well studied in young Inuit children.

Aging and exercise: Perceptions of the active lived-body.

Exploring older people's evocation of their positive experiences of aging has been proposed as a counterweight to the Western stereotype of aging as a process of decline. The aim of this article is to explore how aging women, who participate regularly in group exercise classes, perceive their own bodies and the bodies of others. This article reports on the findings from interviews with 16 women between the age of 70 and 85. We analyzed the data using qualitative content analysis. Two overarching and interrelated themes concerning body perception emerged from the interviews: "The aging body and appearance" and "The body as subject and object." The binary discourse of old age, as either a decline or a success appears in our findings. The training contributes to a sense of well-being experienced through perceived increased physical abilities, self- image and self-esteem. Physical ability was perceived as being more important than appearance by the participants in this study, considering their preconception of an association between declining health, abilities, and older age. Involvement in physical activity appears to play a significant role in the perception of the women's own aging. Although physical attractiveness is a desirable outcome, the most important positive impact of the group exercise was related to increased social belonging and well-being, physical abilities, and capabilities. Thus implications for practice suggests that an intensive group training contributes to the opinion that an aging body is not necessarily a barrier to positive and successful aging.

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.

This study examined the influence of walkability on walking behaviour and assessed whether associations varied according to life-stage and population center (PC) size. Walkability scores were obtained for the six-digit postal codes of residential neighbourhoods of 11,200 Canadians, who participated in biennial assessments of the National Population Health Survey from 1994 to 2010. Participants were stratified by age-group. Mixed-effects logistic regression models were used to estimate the influence of cumulative exposure to neighborhood walkability on utilitarian and exercise walking by PC size and life-stage. Associations of neighbourhood walkability with utilitarian and exercise walking varied according to age-group and PC size. Exposure to high walkable neighborhoods was associated with utilitarian walking in younger and older adults in all PC sizes, except for older adults living in a medium PC. Living in a highly walkable neighborhood in a large PC was associated with walking for exercise in younger (OR: 1.42; 95%CI: 1.20–1.67) and older adults (OR: 2.09; 95%CI: 1.51–2.89). Living in highly walkable neighbourhood in a medium PC was associated with walking for exercise in older adults (OR: 1.62; 95%CI: 1.15–2.29). These results emphasize the need to consider the size and nature of every community, and the age-group of a population when implementing strategies to promote walking. PMID:29261706

To describe the age at which the geriatric syndromes and frailty become common in community-dwelling men. The Concord Health and Ageing in Men Project involves a population-based sample of 1705 community-dwelling men aged 70 and over from a defined geographic region in Sydney. Data were obtained by physical performance tests, clinical examinations, and questionnaire to determine the prevalence of the following conditions by five-year age group. Poor mobility, recurrent falls, urinary incontinence, dementia and frailty phenotype were all uncommon (less than 10%) in men in their 70s, but the prevalence of each of these conditions exceeded 10% in men aged 85-89. The prevalence of Frailty Index-defined frailty, multimorbidity, polypharmacy and instrumental activities of daily living dependence was constantly high in all age groups. The different health-care needs of the 'old old' aged 85 years and older should be accounted for in health service planning. © 2016 AJA Inc.

Both hands at work: the effect of aging on upper-limb kinematics in a multi-step activity of daily living.

The kinematic performance of basic motor tasks shows a clear decrease with advancing age. This study examined if the rules known from such tasks can be generalized to activities of daily living. We examined the end-effector kinematics of 13 young and 13 elderly participants in the multi-step activity of daily living of tea-making. Furthermore, we analyzed bimanual behavior and hand dominance in the task using different conditions of execution. The elderly sample took substantially longer to complete the activity (almost 50%) with longer trajectories compared with the young sample. Models of multiple linear regression revealed that the longer trajectories prolonged the trial duration in both groups, and while movement speed influenced the trial duration of young participants, phases of inactivity negatively affected how long the activity took the elderly subjects. No differences were found regarding bimanual performance or hand dominance. We assume that in self-paced activities of daily living, the age-dependent differences in the kinematics are more likely to be based on the higher cognitive demands of the task rather than on pure motor capability. Furthermore, it seems that not all of the rules known from basic motor tasks can be generalized to activities of daily living.

Global scale up of antiretroviral therapy is changing the context of HIV-related stigma. However, stigma remains an ongoing concern in many countries. Groups of people living with HIV can contribute to the reduction of stigma. However, the pathways through which they do so are not well understood. This paper utilizes data from a qualitative study exploring the impact of networked groups of people living with HIV in Jinja and Mbale districts of Uganda. Participants were people living with HIV (n=40), members of their households (n=10) and their health service providers (n=15). Data were collected via interviews and focus group discussions in 2010, and analyzed inductively to extract key themes related to the approaches and outcomes of the groups' anti-stigma activities. Study participants reported that HIV stigma in their communities had declined as a result of the collective activities of groups of people living with HIV. However, they believed that stigma remained an ongoing challenge. Gender, family relationships, social and economic factors emerged as important drivers of stigma. Challenging stigma collectively transcended individual experiences and united people living with HIV in a process of social renegotiation to achieve change. Groups of people living with HIV provided peer support and improved the confidence of their members, which ultimately reduced self-stigma and improved their ability to deal with external stigma when it was encountered. Antiretroviral therapy and group-based approaches in the delivery of HIV services are opening up new avenues for the collective participation of people living with HIV to challenge HIV stigma and act as agents of social change. Interventions for reducing HIV stigma should be expanded beyond those that aim to increase the resilience and coping mechanisms of individuals, to those that build the capacity of groups to collectively cope with and challenge HIV stigma. Such interventions should be gender sensitive and should

Art-of-Living Training: Developing an Intervention for Students to Increase Art-of-Living.

Art-of-living describes a mindful and self-determined way of dealing with one's self and way of life. It is related to measures of well-being. Art-of-living is based on strategies and attitudes which can be learned and therefore can be changed. Two types of training for students to increase art-of-living were developed and tested in two studies to determine the effects on art-of-living measures. Study 1 dealt with the initial examination of whether it is possible to enhance the art-of-living by training selected art-of-living strategies. Therefore, training with three conditions was developed and conducted with secondary school students (ages 16-19). In Study 2, a second art-of-living training was developed and conducted with children from primary school (ages 8-11). In Study 1, the art-of-living measures increased significantly for the training conditions compared to a control group. In addition, Study 2 showed that higher levels of the art-of-living lead to a better quality of life. In summary, the training successfully enhanced art-of-living. Limitations on and benefits of utilising the art-of-living training are discussed. © 2016 The International Association of Applied Psychology.

Survival after pathogen exposure in group-living insects: don't forget the stress of social isolation!

PubMed

Kohlmeier, P; Holländer, K; Meunier, J

A major cost of group-living is its inherent risk of pathogen infection. To limit this risk, many group-living animals have developed the capability to prophylactically boost their immune system in the presence of group members and/or to mount collective defences against pathogens. These two phenomena, called density-dependent prophylaxis and social immunity, respectively, are often used to explain why, in group-living species, individuals survive better in groups than in isolation. However, this survival difference may also reflect an alternative and often overlooked process: a cost of social isolation on individuals' capability to fight against infections. Here, we disentangled the effects of density-dependent prophylaxis, social immunity and stress of social isolation on the survival after pathogen exposure in group-living adults of the European earwig Forficula auricularia. By manipulating the presence of group members both before and after pathogen exposure, we demonstrated that the cost of being isolated after infection, but not the benefits of social immunity or density-dependent prophylaxis, explained the survival of females. Specifically, females kept constantly in groups or constantly isolated had higher survival rates than females that were first in groups and then isolated after infection. Our results also showed that this cost of social isolation was absent in males and that social isolation did not reduce the survival of noninfected individuals. Overall, this study gives a new perspective on the role of pathogens in social evolution, as it suggests that an apparently nonadaptive, personal immune process may promote the maintenance of group-living under pathogenic environments. © 2016 European Society For Evolutionary Biology.

Misclassification due to age grouping in measures of child development.

Veldhuizen, Scott; Rodriguez, Christine; Wade, Terrance J; Cairney, John

2015-03-01

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.

The purpose of this feasibility study was to investigate whether Māori of advanced age would be interested in and able to take part in a quantitative study involving a comprehensive questionnaire, physical health assessment and blood analyses (a range of biological markers). The study also aimed to involve older Māori in all stages: development of research questions, review of assessment techniques and interpretation of results. Māori aged 75-79 years living in the Bay of Plenty and Lakes DHB areas were invited to participate in a feasibility study covering a wide range of quantitative health related questions. After informed consent interviews and physical assessments were conducted in participants' homes or at a local clinic by Māori health providers contracted as a research partner. For those who gave informed consent specifically for blood analyses, bloods were taken and analysed for defined biological markers of inflammation and ageing. All physical assessments and blood analyses were forwarded to each participant's own general practitioner and relevant guidance was given by the research team. Collective results from 33 Māori participants are presented and cover: Te Reo Māori me ona tikanga (Māori language and cultural knowledge), tribal and whanau (extended family) links, cultural values and religion, whanau engagement and recreational activities, health status, healthy eating and discrimination. The Te Whare Tapa Wha model of health and the Poutama model of human development are utilised to provide an overall framework and context to present the results in respect of our participants and to celebrate their 'advanced' old age. The feasibility study has been successful in engagement with older Māori. It has paved the way to implement a subsequent longitudinal study which aims to enrol 600 Māori aged 80 to 90 years and 600 non-Māori aged 85 years in the Bay of Plenty and Lakes District Health Board areas (Tauranga, Rotorua, Whakatane, Opotiki and Te

Healthy ageing is a concept that concerns older persons' quality of life and is a key factor in promoting well-being. The older population in Thailand is growing. Isan (a region of north-eastern Thailand) has been reported as having one of the most rapidly increasing older populations in the country. In order to care for and promote the health of older people, healthcare providers should understand how healthy ageing is perceived by this target group. Although healthy ageing has been studied in different contexts as well as perspectives, no studies have previously focused on older persons' experiences of healthy ageing from a lifeworld perspective in Isan-Thai. Therefore, the aim of this study is to describe older persons' qualitatively different conceptions of healthy ageing in Isan-Thai culture. A phenomenographic approach with an epistemological base in lifeworld theory was used to disclose the various ways to conceptualize healthy ageing. Individual, qualitative interviews were conducted with 17 people aged 60 and above who live in Isan-Thai. The findings of this study revealed three categories of descriptions: "being independent in dependence," "being at peace," and "being a valuable person." This study also found family members, friends, healthcare providers, and religion important to healthy ageing in the Isan-Thai culture. Understanding how older people conceptualize healthy ageing is valuable for healthcare providers. They can apply these findings regarding healthy ageing in their fieldwork when caring for older people.

Avoiding institutional outcomes for older adults living with disability: the use of community-based aged care supports.

Most people with a disability want to remain living in their own home as they age. Without additional support, people with a disability may not be able to avoid moving into residential aged care, attending day programs, or becoming isolated from participation in the wider community. This study examined whether participants perceived access to community-based aged care supports assisted with avoiding receiving more institutional models of service as they age. Qualitative research processes were used to explore the perceptions of 60 individuals with a disability aged 50 years and over, in relation to ageing and the value of community-based aged care. Findings indicated that participants receiving community-based aged care supports reported benefits including opportunities to develop relationships, maintain daily living skills and participate in community activities. Due to a lack of confidence in the availability of access to mainstream community-based aged care services, many participants felt vulnerable or unsure about their future and ability to remain living in their own home. Several participants commented that this meant that an undesired early relocation into residential aged care or congregate disability services appeared inevitable.

Given the shortage of kidneys for transplant, living kidney donation (LKD) is increasingly used to expand the organ donor pool. Although Hispanics/Latinos need disproportionately more kidney transplants, they receive a smaller proportion of living donor kidney transplants than other ethnic/racial groups. To assess Hispanics' awareness, perceptions, misconceptions, cultural beliefs, and values about and barriers to LKD. Nine focus groups were conducted with 76 adult Hispanics in Chicago, Illinois, between January and March 2012. Focus groups included kidney transplant recipients, living kidney donors, dialysis patients, and the general Hispanic public. Several themes emerged as perceived barriers to LKD. Many participants identified knowledge deficits about LKD, expressing uncertainty about the differences between LKD and deceased donation, and whether kidney disease simultaneously afflicts both kidneys. Many believed that donors experience dramatically shorter life expectancies, are unable to have children, and are more susceptible to kidney disease after donating. Recipients and donors reported that family members were involved in discussions about the donor's decision to donate, with some family members discouraging donation. Financial barriers cited included fear of becoming unable to work, losing one's job, or being unable to pay household bills while recovering. Participants also identified logistic barriers for undocumented immigrants (eg, the inability to obtain government insurance for transplant candidates and uncertainty about their eligibility to donate). Donors desired information about optimizing self-care to promote their remaining kidney's health. Culturally competent interventions are needed to redress Hispanics' knowledge deficits and misconceptions and reduce LKD disparities among Hispanics.

A culture of education: Enhancing school performance of youth living in residential group care in Ontario.

This article presents a synthesis of what is known about the educational experiences of youth living in residential group care based on a literature review that highlights both the experiences of the youth themselves and the operational context of residential group care in Ontario as it pertains to educational performance. The author argues that there is little emphasis on education within the residential group care sector in Ontario that could translate into more productive educational experiences for youth. The article then provides a framework for developing a culture of education for residential group care that can be acted upon expeditiously. Enhancing the educational performance of young people living in group care will require a cultural approach that provides for daily and pervasive education supports and encouragement, and aims to enhance the lived experience of young people pursuant to their education.

To predict the cost of a delivery following assisted reproductive technologies (ART). Cost analysis based on retrospective chart analysis. University-based ART program. Women aged >or=26 and age and basal FSH was used to estimate the probability of a live birth. Cost analysis was applied to the resulting prediction. The predicted probability of a live birth following ART based on a woman's age and FSH and the associated cost of a live birth. Analysis of 1,238 first ART cycles produced a prediction model for live birth rates following ART incorporating both age and FSH. A cost analysis based upon combination of age and FSH revealed the cost of a live birth exceeded $100,000 when the probability of a live birth fell below 15% and the cost rose exponentially at lower probabilities of live birth. Based upon a woman's age and FSH and expected cost for a live birth using ART may be calculated. At live birth rates <5%, the cost of ART is high and greatly exceeds the cost of donor cycles. This information is vital for patient counseling.

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

In our study, health risk levels of different age groups of residents living in the vicinity of a municipal solid waste incinerator (MSWI) posed by polychlorinated dibenzo-p-dioxins and polychlorinated dibenzofurans (PCDD/Fs) in atmosphere and soil were evaluated. The toxic equivalent concentrations of PCDD/Fs (TEQ) in surrounding atmosphere and soil of studied MSWI were 0.05-0.12 pg I-TEQ Nm -3 and 7.622-15.450 ng I-TEQ kg -1 , respectively. The PCDFs/PCDDs (F/D) values of PCDD/Fs in surrounding atmosphere of studied MSWI ranged from 0.40 to 5.90 with a mean of 1.80, suggesting that the PCDD/Fs mainly came from combustion sources and studied MSWI could be a key source of PCDD/Fs in surrounding atmosphere. The F/D ratios of PCDD/Fs in surrounding soil ranged from 0.18 to 1.81 with a mean of 0.90, suggesting combustion is not the mainly sources of PCDD/Fs in surrounding soil, and studied MSWI may have limited influence on PCDD/Fs in surrounding soil. O8CDD and 2,3,4,7,8-P5CDF could be the total PCDD/Fs and TEQ indicators in surrounding atmosphere of studied MSWI, respectively. The carcinogenic risk (CR) values of PCDD/Fs in surrounding atmosphere and soil for children, teens and adults were 1.24E-06, 9.06E-07 and 4.41E-06, respectively, suggesting that the potential cancer risk occurred but the risk was at acceptable levels for both children and adults (<1.00E-05), and the cancer risk for teens was negligible (<1.00E-06). The non-carcinogenic risk (non-CR) values of three age groups were lower than 1, indicating that no obvious non-carcinogenic effects occurred. Inhalation of air was the largest contributor of health risk (both CR and non-CR) for three age groups. In addition, a comparison of the health risk between PCDD/Fs and other emerging contaminants and traditional pollutants in soil and atmosphere was performed, which will help us have a good view of the health risk levels of PCDD/Fs in surrounding environment of MWSI.

Caloric restriction (CR) has long been known to increase median and maximal lifespans and to decreases mortality and morbidity in short-lived animal models, likely by altering fundamental biological processes that regulate aging and longevity. In rodents, CR was reported to delay the aging of the immune system (immune senescence), which is believed to be largely responsible for a dramatic increase in age-related susceptibility to infectious diseases. However, it is unclear whether CR can exert similar effects in long-lived organisms. Previous studies involving 2- to 4-year CR treatment of long-lived primates failed to find a CR effect or reported effects on the immune system opposite to those seen in CR-treated rodents. Here we show that long-term CR delays the adverse effects of aging on nonhuman primate T cells. CR effected a marked improvement in the maintenance and/or production of naïve T cells and the consequent preservation of T cell receptor repertoire diversity. Furthermore, CR also improved T cell function and reduced production of inflammatory cytokines by memory T cells. Our results provide evidence that CR can delay immune senescence in nonhuman primates, potentially contributing to an extended lifespan by reducing susceptibility to infectious disease.

Recovery of sensorimotor function and activities of daily living after cervical spinal cord injury: the influence of age.

PubMed

Wirz, Markus; Dietz, Volker

2015-02-01

This retrospective study was designed to examine the influence of age on the outcome of motor function and activities of daily living (ADLs) in patients with a cervical spinal cord injury (SCI). The study is based on the data registry of the European Multicenter Study of Spinal Cord Injury (EMSCI) study group. Initial upper-extremity motor score (UEMS) and its change over 5 months, as well as the initial Spinal Cord Independence Measure (SCIM) score, did not differ between younger adults (20-39 years) and elderly (60-79 years) patients. However, the change in SCIM score over 5 months was significantly greater in the younger patient group. Initial UEMS, SCIM, and ulnar compound motor action potentials (CMAP), reflecting peripheral nerve damage (motoneurons and roots), were significantly greater in incomplete, compared to complete, SCI, regardless of age group. The initial assessment of UEMS in combination with CMAP recordings allows an early prediction of ADLs outcomes in both younger adults and elderly subjects. The impaired translation of gain in motor score into increased ADL independence in elderly patients requires specifically tailored rehabilitation programs.

It was found that the rate of aging of 17 month old rats which had been exposed to 3.14 times normal gravity in an animal centrifuge for 8 months was larger than that of the controls as determined by the apparently elevated lipofuscin content in heart and kidney, reduced numbers and increased size of mitochondria of heart tissue, and inferior liver mitochondria respiration. Steady-state food intake per day per kg body weight, which is presumably proportional to rate of living or specific basal metabolic expenditure, was found to be about 18 percent higher than in the controls after an initial 2 month adaptation period. Although half of the centrifuged animals lived only a little shorter than the controls (average about 343 vs. 364 days on the average, statistically nonsignificant), the remaining half (longest survivors) lived on the centrifuge an average of 520 days (range 483-572) compared to an average of 574 days (range 502-615) for the controls, computed from the onset of centrifugation, or 11 percent shorter. These findings indicate that a moderate increase of the level of basal metabolism of young adult rats adapted to hypergravity compared to controls in normal gravity is accompanied by a roughly similar increase in the rate of organ aging and reduction of survival, in agreement with Pearl's (1928) rate of living theory of aging, previously experimentally demonstrated only in poikilotherms.

2017-01-01

The article presents a methodical approach for prediction of life expectancy for people diagnosed with prostate cancer based on the kinetic theory of aging of living systems. The life expectancy is calculated by solving the differential equation for the rate of aging for three different stage of life - «normal» life, life with prostate cancer and life after combination therapy for prostate cancer. The mathematical model of aging for each stage of life has its own parameters identified by the statistical analysis of healthcare data from the Zharinov's databank and Rosstat CDR NES databank. The core of the methodical approach is the statistical correlation between growth rate of the prostate specific antigen level (PSA-level) or the PSA doubling time (PSA DT) before therapy, and lifespan: the higher the PSA DT is, the greater lifespan. The patients were grouped under the «fast PSA DT» and «slow PSA DT» categories. The satisfactory matching between calculations and experiment is shown. The prediction error of group life expectancy is due to the completeness and reliability of the main data source. A detailed monitoring of the basic health indicators throughout the each person life in each analyzed group is required. The absence of this particular information makes it impossible to predict the individual life expectancy.

The risk factors responsible for acute rheumatic fever (ARF) are complex, in part, because group A streptococcus (GAS) infection is a prerequisite for this disease. We attempted to differentiate socioeconomic from genetic risk factors by studying subjects in a Hawaii pediatric cardiology clinic who qualified for Medicaid. This ethnically diverse group was unique because they maintained a low socioeconomic but generally healthy lifestyle with more limited risks than those living in extremely impoverished conditions. Methods Questionnaires were administered to consenting subjects in the clinic, who were divided into those diagnosed with ARF (n=26) and those with other (primarily congenital) heart diseases (n=41). Results The socioeconomic status of the ARF and non-ARF groups was lower than that of the Hawaii population in general, and little differences were noted between the groups. The ARF group, however, had slightly larger household sizes and more children than the non-ARF group. The greatest difference was in ethnicity. By the Fisher exact test, the number of Polynesians belonging to the ARF group was significantly greater than all other ethnicities (P=.005). Polynesians had an odds ratio >4.80 of developing ARF, which increased to 6.33 when number of children per household was considered. Conclusion The potential contribution of genetic predisposing factors for developing ARF was analyzed in subjects living in a homogeneously low socioeconomic level relative to the general Hawaii population. Polynesians were at highest risk when compared to other ethnicities living in similar socioeconomic conditions. PMID:17200684

To assess whether women with polycystic ovary syndrome (PCOS) follow the same age-related decline in IVF outcomes as women with tubal factor infertility over the reproductive life span. PCOS is characterized by increased ovarian reserve as assessed by antral follicle counts and anti-Müllerian hormone levels. It is unclear whether these surrogate markers of ovarian reserve reflect a true lengthening of the reproductive window. Retrospective cohort. Not applicable. Women with PCOS and tubal factor infertility (42,286 cycles). IVF. Pregnancy and live-birth rates. The mean number of oocytes retrieved was higher in women with PCOS compared with in women with tubal factor (16.4 vs. 12.8; odds ratio [OR], 1.27; 95% confidence interval [CI], 1.25-1.29). The clinical pregnancy (42.5% vs. 35.8%; OR, 1.32; 95% CI, 1.27-1.38) and live-birth rates were also increased in women with PCOS (34.8% vs. 29.1%; OR, 1.30; 95% CI, 1.24-1.35). A similar rate of decline in clinical pregnancy and live-birth rates was noted in both groups (20-44 years). The implantation, clinical pregnancy, miscarriage, and live-birth rates were not significantly different for each year after age 40 in the two groups. Despite a higher oocyte yield in all age groups, women with PCOS over age 40 had similar clinical pregnancy and live-birth rates compared with women with tubal factor infertility. These findings suggest that the reproductive window may not be extended in PCOS and that patients with infertility should be treated in a timely manner despite indicators of high ovarian reserve.

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.

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

By the 2050, it is estimated that the proportion of people over the age of 80 will have risen from 3.9% to 9.1% of population of Organisation for Economic Cooperation and Development countries. A large proportion of these people will need significant help to manage various chronic illnesses, including dementia, heart disease, diabetes, limited physical movement and many others. Current approaches typically focus on acute episodes of illness and are not well designed to provide adequately for daily living care support. In our rapidly ageing society, a critical need exists for effective, affordable, scalable and safe in-home and in-residential care solutions leveraging a range of current and emerging sensor, interaction and integration technologies. Key aims are to support the ageing to live longer in their own homes; make daily challenges associated with ageing less limiting through use of technology supports; better support carers - both professional and family - in providing monitoring, proactive intervention, and community connectedness; enable in-home and in-residential care organisations to scale their support services and better use their workforces; and ultimately provide better quality of life. Deakin University researchers have been investigating a range of emerging technologies and platforms to realise this vision, which we in broad terms coin Digital Enhanced Living, in the ageing space but also supporting those with anxiety and depression, sleep disorders, various chronic diseases, recovery from injury, and various predictive analytics.

Introduction. Obesity is defined by the World Health Organization (WHO) as a disease characterized by the excessive accumulation of body fat. Obesity is considered a public health problem, leading to serious social, psychological and physical problems. However, the appropriate cut-off point of body mass index (BMI) based on body fat percentage (BF%) for classifying an individual as obese in middle-aged adults living in Rio de Janeiro remains unclear. Materials and methods. This was a prospective cross-sectional study comprising of 856 adults (413 men and 443 women) living in Rio de Janeiro, Brazil ranging from 30-59 years of age. The data were collected over a two year period (2010-2011), and all participants were underwent anthropometric evaluation. The gold standard was the percentage of body fat estimated by bioelectrical impedance analysis. The optimal sensitivity and specificity were attained by adjusting BMI cut-off values to predict obesity based on the WHO criteria: BF% >25% in men and >35% in women, according to the receiver operating characteristic curve (ROC) analysis adjusted for age and for the whole group. Results. The BMI cut-offs for predicting BF% were 29.9 kg/m2 in men and 24.9 kg/m2 in women. Conclusions The BMI that corresponded to a BF% previously defining obesity was similar to that of other Western populations for men but not for women. Furthermore, gender and age specific cut-off values are recommended in this population. Significance for public health World Health Organization (WHO) defines obesity as a disease characterized by the excessive accumulation of body fat. Obesity is considered a public health problem, leading to serious social, psychological and physical problems. The WHO suggested cut-off point for obesity is a body mass index (BMI) of 30 kg/m2, which is associated with morbidity and mortality. An important issue in the debate over measuring obesity concerns the use of BMI to define obesity across different populations. However

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.

Telomeres, Age and Reproduction in a Long-Lived Reptile

2012-01-01

A major interest has recently emerged in understanding how telomere shortening, mechanism triggering cell senescence, is linked to organism ageing and life history traits in wild species. However, the links between telomere length and key history traits such as reproductive performances have received little attention and remain unclear to date. The leatherback turtle Dermochelys coriacea is a long-lived species showing rapid growth at early stages of life, one of the highest reproductive outputs observed in vertebrates and a dichotomised reproductive pattern related to migrations lasting 2 or 3 years, supposedly associated with different environmental conditions. Here we tested the prediction of blood telomere shortening with age in this species and investigated the relationship between blood telomere length and reproductive performances in leatherback turtles nesting in French Guiana. We found that blood telomere length did not differ between hatchlings and adults. The absence of blood telomere shortening with age may be related to an early high telomerase activity. This telomere-restoring enzyme was formerly suggested to be involved in preventing early telomere attrition in early fast-growing and long-lived species, including squamate reptiles. We found that within one nesting cycle, adult females having performed shorter migrations prior to the considered nesting season had shorter blood telomeres and lower reproductive output. We propose that shorter blood telomeres may result from higher oxidative stress in individuals breeding more frequently (i.e., higher costs of reproduction) and/or restoring more quickly their body reserves in cooler feeding areas during preceding migration (i.e., higher foraging costs). This first study on telomeres in the giant leatherback turtle suggests that blood telomere length predicts not only survival chances, but also reproductive performances. Telomeres may therefore be a promising new tool to evaluate individual reproductive

"Move or Suffer": Is Age-Segregation the New Norm for Older Americans Living Alone?

Despite ethical claims that civic societies should foster intergenerational integration, age-segregation is a widespread yet understudied phenomenon. The purpose of this study was to understand the reasons that led community-dwelling older Americans to relocate into senior housing. Qualitative data were collected through participant observation and ethnographic interviews with 47 older adults living alone in San Francisco, California. Half of study participants lived in housing for seniors, the other half in conventional housing. Data were analyzed with standard qualitative methods. Findings illuminate the dynamics that favor age-segregation. Senior housing might be cheaper, safer, and offer more socializing opportunities than conventional housing. Yet, tenants of senior housing may also experience isolation, crime, and distress. Findings suggest that rather than individual preference, cultural, political, and economic factors inform the individual decision to relocate into age-segregated settings. Findings also call for an increased awareness on the ethical implications of societies increasingly segregated by age. © The Author(s) 2014.

Quadrivalent live attenuated influenza vaccine (Q/LAIV) was licensed in 2012 and replaced trivalent live attenuated influenza vaccine in the United States during the 2013-2014 influenza season. This study assessed the safety of Q/LAIV in children and adults aged 2-49years. This was a prospective observational cohort study using data collected from Kaiser Permanente Northern California. Post-vaccination events of interest were any hospitalization, hospitalization for lower respiratory tract infection, and the following medically attended events: hypersensitivity, seizures/convulsions, lower respiratory tract infection, wheezing, Guillain-Barré syndrome, Bell's palsy, encephalitis, neuritis, vasculitis, and narcolepsy/cataplexy. The rates of these events during the risk interval post-vaccination were compared with rates observed during reference periods later in the follow-up (within-cohort analysis) and with rates observed in frequency-matched unvaccinated controls and inactivated influenza vaccine (IIV) recipients. A total of 62,040 eligible Q/LAIV recipients were identified during the 2013-2014 influenza season. Within-cohort comparisons of all Q/LAIV recipients as well as comparisons between Q/LAIV recipients and unvaccinated controls or IIV recipients did not show any significantly higher risk of hospitalizations or medically attended events following administration of Q/LAIV. Additional analyses by setting (clinic visits, emergency department visits, and hospital admissions) and age group (2-4, 5-8, 9-17, and 18-49years) also did not reveal clinically consistent findings that suggested any increased risk after administration of Q/LAIV. In this large population study of individuals aged 2-49years, no safety signals associated with the administration of Q/LAIV were observed. A much larger study population would be needed to confidently reject any association between Q/LAIV and very rare events, specifically those with an incidence of <1 event/10,000 person

Ageing and the group-reference effect in memory.

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.

In order to reveal patterns of reproductive aging in birds we focus on a short lived species, the Japanese quail and the American kestrel, which has a life span of medium length. Quail have been studied extensively in the laboratory as models for understanding avian endocrinology and behavior, and as a subject for toxicological research and testing. In the lab, Japanese quail show age-related deterioration in endocrine, behavioral, and sensory system responses; the American kestrel is relatively long lived and shows moderate evidence of senescence in the oldest birds. Using data collected from captive kestrels at the Patuxent Wildlife Research Center, a database was designed to document selected parameters over the life cycle of the kestrels. Life table data collated from many species indicate that longer lived species of birds show senescence in survival ability but this pattern has not been established for reproductive function. We suggest that useful comparisons among species can be made by identifying stages in reproductive life history, organized on a relative time scale. Preliminary data from quail and kestrels, admittedly only two species, do not yet indicate a pattern of greater reproductive senescence in longer-lived birds.

Stunting remains a major public health concern worldwide. Although its global prevalence is slowly decreasing, the actual number of affected children is still rising in Sub-Saharan Africa. In the Central African Republic (CAR), about one third of all children below the age of five are stunted. Stunting is correlated with many long-term consequences, including poor cognitive development and a higher rate of morbidity and mortality, making stunting a major contributor to poverty. In CAR, little is known about the factors that contribute to stunting. This study aimed at analysing, in a cross-sectional study, the main factors associated with stunting in a group of 414 children recruited between December 2011 and November 2013, aged five years or less and living in Bangui. For all children, demographic, socio-economic and anthropometric data were recorded and asymptomatic enteropathogen carriage was assessed in stool samples using classical microbiological assays. The study group had a mean age of 14.2±10 months. Fifty-eight percent (292/414) were boys, and 36 percent (148/414) exhibited stunted growth. Of the stunted children, 51% (75/148) showed a moderate delay in linear growth for their age group [height-for-age z-score (HAZ) between -2 and -3 SD] while 49% (73/148) presented a severe delay (HAZ < -3). Factors significantly associated with stunting included gender (aOR: 1.67; 95% CI: 1.07; 2.62 for boys compared to girls) and age (aOR of 3.98 (95% CI: 2.45; 6.46) for toddlers and aOR 4.42 (95% CI: 2.36; 8.28) for children compared to infants). Most importantly, we identified being overweight [weight-for-height z-score (WHZ) > 2 SD; aOR: 3.21; 95% CI: 1.50; 6.90 of overweight compared to normal weight] as also being significantly associated with stunting. This is the first study showing that even in the poorest countries of the world there is an association of stunting with being overweight.

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.

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.

Group living is thought to evolve whenever individuals attain a net fitness advantage due to reduced predation risk or enhanced foraging efficiency, but also when individuals are forced to remain in groups, which often occurs during high-density conditions due to limitations of critical resources for independent breeding. The influence of ecological limitations on sociality has been studied little in species in which reproduction is more evenly shared among group members. Previous studies in the caviomorph rodent Octodon degus (a New World hystricognath) revealed no evidence that group living confers an advantage and suggest that burrow limitations influence formation of social groups. Our objective was to examine the relevance of ecological limitations on sociality in these rodents. Our 4-year study revealed no association between degu density and use of burrow systems. The frequency with which burrow systems were used by degus was not related to the quality of these structures; only in 1 of the 4 years did the frequency of burrow use decrease with decreasing abundance of food. Neither the number of females per group nor total group size (related measures of degu sociality) changed with yearly density of degus. Although the number of males within social groups was lower in 2008, this variation was not related clearly to varying density. The percentage of females in social groups that bred was close to 99% and did not change across years of varying density. Our results suggest that sociality in degus is not the consequence of burrow limitations during breeding. Whether habitat limitations contribute to variation in vertebrate social systems is discussed. PMID:22328789

Dominance relationships among siamang males living in multimale groups.

PubMed

Morino, Luca

2016-03-01

Intense intolerance among males is considered to be an important mechanism maintaining the uni-male organization traditionally attributed to socially monogamous gibbons. Long-term field work, however, has revealed the existence of stable, socially polyandrous groups in at least two populations, raising questions about the mechanism that allows two adult males to co-reside in the same group. I collected 21 months of behavioral data on 7 two-male groups of wild siamangs (Symphalangus syndactylus) in southern Sumatra (Indonesia) to test the hypothesis that dominance relationships regulate the interactions of adult male siamangs and ultimately facilitate multi-male social groups. A dominant male could clearly be identified in each dyad, based on a consistent direction of agonistic interactions, displacements and the maintenance of an advantageous position in the canopy. Males identified as dominant enjoyed greater social access to the resident female and monopolized copulations. These results suggest that gibbons possess the psycho-social flexibility to regulate intra-sexual aggression and live in multi-male social units under certain social conditions. I discuss the effects that relatedness between males and female choice have in determining this grouping pattern, and the role of male intolerance in the maintenance of primate mating systems. © 2015 Wiley Periodicals, Inc.

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

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.

Background Emerging evidence suggests that neighborhood characteristics can have direct and indirect effects on the weight status of the residents. Objectives To assess the relationship between general and central obesity and the neighborhood environment in two ethnic groups (Azeri Turks and Kurds) living in Urmia city, Northwestern Iran. Patients and Methods In this cross-sectional study, 723 participants (427 women and 296 men) aged 20 - 64 years from two ethnic groups (Azeri Turks, n = 445; Kurds, n = 278) were selected from 38 neighborhoods using a combination of cluster, random, and systematic sampling methods. Neighborhood characteristics were obtained by a validated 22-item neighborhood and a health observational checklist. General and central obesity were measured and evaluated using standard methods. Principal component analysis (PCA) was used to define the dominant neighborhood environment. The association of neighborhood characteristics with general and central obesity was analyzed by a logistic regression model. Results Three common neighborhood environments were identified: 1) modern-affluent, 2) central-high access and 3) marginal. These three factors explained 73.2% of the total variance. Overall, the participants living in a higher tertile of the central-high access neighborhoods had an increased chance of central obesity (OR = 1.63, 95% CI: 1.13 - 2.34). Azeri Turks living in the highest tertile of the modern-affluent neighborhoods had a significantly higher likelihood of having general obesity (OR = 2.49, 95% CI: 1.37 - 4.01). Adjustment for age, gender, marital status, socioeconomic status (SES), energy intake, and physical activity did not change the results. However, after adjustment for educational level, the association was not significant. Conclusions The findings point to a relationship between neighborhood characteristics and obesity only in the Azeri Turks. However, educational level was more important than neighborhood quality in

To examine the relationship between body mass index (BMI) and subjective well-being (SWB) among long-lived women over 95 years of age and evaluate whether this relationship is mediated by functional ability. Retrospective cohort study. Data from the Rugao longevity cohort, a population-based study in Rugao, China. A sample of 342 long-lived women (mean age 97.4 ± 2.1, range 95-107) whose SWB and other covariates were available were included in this study. BMI was calculated as weight in kilograms divided by height in meters-squared (kg/m(2)). SWB was measured by life satisfaction (LS), positive affect (PA), negative affect (NA) and affect balance (AB). Functional ability was assessed by the Katz Index of Activities of Daily Living (ADL). According to BMI classification standards for China, the underweight group had lower levels of LS than the normal and overweight groups (28.62 vs. 30.51 and 31.57, respectively; p<.05). Correlation analysis showed that BMI was significantly related to LS (r = 0.166, p<.01). The strength of the BMI and LS association was diminished when ADL was included in the general linear regression models. Mediation analysis revealed that ADL mediated this relationship (effect size = 22.6%). We did not observe significant associations of BMI with other SWB components (PA, NA, and AB). For long-lived women, low BMI, rather than elevated BMI, is an indicator of poor psychological well-being. The findings call for public health awareness about low body weight in long-lived women, especially in those with physical disabilities when focusing on quality of life.

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

Populations around the world are rapidly ageing and effective treatment for HIV means women living with HIV (WLHIV) can live longer, healthier lives. HIV testing and screening programmes and safer sex initiatives often exclude older sexually active WLHIV. Systematically reviewing the literature to inform World Health Organization guidelines on the sexual and reproductive health and rights (SRHR) of WLHIV, identified four studies examining healthy sexuality among older WLHIV. In Uganda, WLHIV reported lower rates of sexual activity and rated sex as less important than men. In the United States, HIV stigma, disclosure, and body image concerns, among other issues, were described as inhibiting relationship formation and safer sexual practices. Sexual activity declined similarly over time for all women, including for WLHIV who reported more protected sex, while a significant minority of WLHIV reported unprotected sex. A single intervention, the "ROADMAP" intervention, demonstrated significant increases in HIV knowledge and decreases in HIV stigma and high risk sexual behaviour. WLHIV face ageist discrimination and other barriers to remaining sexually active and maintaining healthy sexual relationships, including challenges procuring condoms and seeking advice on safe sex practices, reduced ability to negotiate safer sex, physical and social changes associated with menopause, and sexual health challenges due to disability and comorbidities. Normative guidance does not adequately address the SRHR of older WLHIV, and while this systematic review highlights the paucity of data, it also calls for additional research and attention to this important area.

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

Background Older home-living people are an at-risk group for undernutrition, particularly those who are living alone. Lack of knowledge about healthy dietary habits, altered taste sensation, and declined health status are shown to be some of the factors related to undernutrition. The aims of this study were to explore how a small group of older people in Southern Norway perceived their nutritional self-care. Methods An exploratory qualitative approach, combined with a simple self-report questionnaire, was used. Five persons living in rural areas in Southern Norway, who in a former study were screened and found to be at risk for undernutrition, participated. Qualitative data assessed by means of individual self-care talks in the persons’ own homes were analyzed using directed content analysis. A simple self-report questionnaire containing demographic variables, two health-related questions, and the Nutritional Form For the Elderly (NUFFE-NO) instrument was filled out at baseline and 6 months after the self-care talks. Results The qualitative data showed that the participants had adequate knowledge about healthy and nutritious diets. They were aware of and motivated to adapt their diet to their current state of health and to perform the necessary actions to maintain an optimal nutritional status and nutritional self-care. Conclusion Older people living at home are a diverse group. However, this study showed that they may have sufficient knowledge, willingness, and ability to perform nutritional self-care, even if they live alone and have several chronic illnesses and impaired health.

Old age pension and intergenerational living arrangements: a regression discontinuity design

PubMed Central

2017-01-01

China launched a pension program for rural residents in 2009, now covering more than 300 million Chinese. This program offers a unique setting for studying the ageing population, given the rapidity of China’s population ageing, traditions of filial piety and co-residence, decreasing number of children, and dearth of formal social security, at a relatively low income level. This paper examines whether receipt of the old-age pension payment equips elderly parents and their adult children to live apart and whether parents substitute children’s time involved in instrumental support to them with service consumption. Employing a regression discontinuity design to a primary longitudinal survey conducted in Guizhou province of China, this paper overcomes challenges in the literature that households eligible for pension payment might be systematically different from ineligible households and that it is difficult to separate the effect of pension from that of age or cohort heterogeneity. Around the pension eligibility age cut-off, results reveal large and significant reduction in intergenerational co-residence of the extended family and increase in service consumption among elderly parents.

Background In group-living animals, social interactions and their effects on other life activities such as foraging are commonly determined by discrimination among group members. Accordingly, many group-living species evolved sophisticated social recognition abilities such as the ability to recognize familiar individuals, i.e. individuals encountered before. Social familiarity may affect within-group interactions and between-group movements. In environments with patchily distributed prey, group-living predators must repeatedly decide whether to stay with the group in a given prey patch or to leave and search for new prey patches and groups. Methodology/Principal Findings Based on the assumption that in group-living animals social familiarity allows to optimize the performance in other tasks, as for example predicted by limited attention theory, we assessed the influence of social familiarity on prey patch exploitation, patch-leaving, and inter-patch distribution of the group-living, plant-inhabiting predatory mite Phytoseiulus persimilis. P. persimilis is highly specialized on herbivorous spider mite prey such as the two-spotted spider mite Tetranychus urticae, which is patchily distributed on its host plants. We conducted two experiments with (1) groups of juvenile P. persimilis under limited food on interconnected detached leaflets, and (2) groups of adult P. persimilis females under limited food on whole plants. Familiar individuals of both juvenile and adult predator groups were more exploratory and dispersed earlier from a given spider mite patch, occupied more leaves and depleted prey more quickly than individuals of unfamiliar groups. Moreover, familiar juvenile predators had higher survival chances than unfamiliar juveniles. Conclusions/Significance We argue that patch-exploitation and -leaving, and inter-patch dispersion were more favorably coordinated in groups of familiar than unfamiliar predators, alleviating intraspecific competition and improving prey

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.

Pupal vibratory signals of a group-living beetle that deter larvae

Kojima, Wataru; Ishikawa, Yukio; Takanashi, Takuma

2012-01-01

Pupae of some insects produce sounds or vibrations, but the function of the sounds/vibrations has not been clarified in most cases. Recently, we found vibratory communication between pupae and larvae of a group-living beetle Trypoxylus dichotoma, which live in humus soil. The vibratory signals produced by pupae were shown to deter approaching larvae, thereby protecting themselves. In the present study, we tested our hypothesis that pupal signals are mimics of vibratory noises associated with foraging of moles, the most common predators of T. dichotoma. Mole vibrations played back in laboratory experiments deterred larval approaches in the same way as pupal signals. These findings suggest that to deter conspecific larvae, pupae of T. dichotoma may have exploited a preexisting response of larvae to predator vibrations by emitting deceptive signals. PMID:22896788

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

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.

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).

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

Stress axis regulation during social ascension in a group-living cichlid fish.

Animals living in groups often form social hierarchies, with characteristic behaviours and physiologies associated with rank. However, when social opportunities arise and a subordinate ascends into a dominant position, quick adjustments are necessary to secure this position. Such periods of social transition are typically associated with elevated glucocorticoid production, but the precise regulation of the stress axis during these occasions is not well understood. Using the group-living cichlid, Neolamprologus pulcher, the effects of social ascension on the stress axis were assessed. Ascenders rapidly filled experimentally created vacancies, adopting a dominant behavioural phenotype within 72 h-elevating aggression, activity, and workload, while receiving high rates of affiliative behaviours from their group members. Despite assuming behavioural dominance within their groups, ascenders displayed higher cortisol levels than dominants three days post-ascension. Additionally, compared to subordinates, ascenders had increased transcript abundance of steroidogenic acute regulatory protein (star) and cytochrome p450 side-chain cleavage enzyme (p450scc) in the head kidney, indicating activation of the stress axis. Cortisol levels were lowest in ascenders that displayed low rates of aggression, potentially reflecting the reestablishment of social stability in these groups. Increased transcript abundance of both glucocorticoid receptors (gr1 and gr2) in the brain's preoptic area (POA) of ascenders compared to dominants suggested an enhanced capacity for cortisol regulation via negative feedback. Our results reveal a regulatory cascade of behavioural and physiological interactions and highlight the importance of investigating the underlying mechanisms regulating the stress axis.

This study examined the extent of low-energy reporting and its relationship with demographic and lifestyle factors in women previously treated for breast cancer. This study used data from a large multisite clinical trial testing the efficacy of a dietary intervention to reduce risk for breast cancer recurrence (Women's Healthy Eating and Living Study). Using the Schofield equation to estimate energy needs and four 24-h dietary recalls to estimate energy intakes, we identified women who reported lower than expected energy intakes using criteria developed by G. R. Goldberg et al. (Eur. J. Clin. Nutr., 45: 569-581, 1991). We examined data from 1137 women diagnosed with stage I, stage II, or stage IIIA primary, operable breast cancer. Women were 18-70 years of age at diagnosis and were enrolled in the Women's Healthy Eating and Living Study between August 19, 1995, and April 1, 1998, within 4 years after diagnosis. The Goldberg criteria classified about one-quarter (25.6%) as low-energy reporters (LERs) and 10.8% as very LERs. Women who had a body mass index >30 were almost twice (odds ratio, 1.95) as likely to be LERs. Women with a history of weight gain or weight fluctuations were one and a half times as likely (odds ratio, 1.55) to be LERs as those who were weight stable or weight losers. Age, ethnicity, alcohol intake, supplement use, and exercise level were also related to LER. Characteristics (such as body mass index, age, ethnicity, and weight history) that are associated with low-energy reporting in this group of cancer survivors are similar to those observed in other populations and might affect observed diet and breast cancer associations in epidemiological studies.

Background Systemic sclerosis, or scleroderma, is a chronic and rare connective tissue disease with negative physical and psychological implications. Sources of emotional distress and the impact they have on the lives of people with scleroderma are not well understood. Objectives To gain an in-depth understanding of the emotional experiences and sources of emotional distress for women and men living with scleroderma through focus group discussions. Methods Three semi-structured focus group discussions were conducted (two in English, one in French) with a total of 22 people with scleroderma recruited through the Scleroderma Society of Ontario in Hamilton, Ontario and a scleroderma clinic in Montreal, Canada. Interviews were recorded, transcribed, and then coded for emerging themes using thematic inductive analysis. Results Core themes representing sources of emotional distress were identified, including: (a) facing a new reality; (b) the daily struggle of living with scleroderma; (c) handling work, employment and general financial burden; (d) changing family roles; (e) social interactions; and (f) navigating the health care system. Collectively, these themes refer to the stressful journey of living with scleroderma including the obstacles faced and the emotional experiences beginning prior to receiving a diagnosis and continuing throughout the participants’ lives. Conclusion Scleroderma was portrayed as being an unpredictable and overwhelming disease, resulting in many individuals experiencing multiple sources of emotional distress. Interventions and supportive resources need to be developed to help individuals with scleroderma and people close to them manage and cope with the emotional aspects of the disease. PMID:27008209

Contrasted patterns of age-specific reproduction in long-lived seabirds.

2009-01-22

While the number of studies providing evidence of actuarial senescence is increasing, and covers a wide range of taxa, the process of reproductive senescence remains poorly understood. In fact, quite high reproductive output until the last years of life has been reported in several vertebrate species, so that whether or not reproductive senescence is widespread remains unknown. We compared age-specific changes of reproductive parameters between two closely related species of long-lived seabirds: the small-sized snow petrel Pagodroma nivea, and the medium-sized southern fulmar Fulmarus glacialoides. Both are sympatric in Antarctica. We used an exceptional dataset collected over more than 40 years to assess age-specific variations of both breeding probability and breeding success. We found contrasted age-specific reproductive patterns between the two species. Reproductive senescence clearly occurred from 21 years of age onwards in the southern fulmar, in both breeding probability and success, whereas we did not report any decline in the breeding success of the snow petrel, although a very late decrease in the proportion of breeders occurred at 34 years. Such a contrasted age-specific reproductive pattern was rather unexpected. Differences in life history including size or migratory behaviour are the most likely candidates to account for the difference we reported in reproductive senescence between these sympatric seabird species.

There is a need for dental age estimation methods after completion of the third molar mineralization. Degenerative dental characteristics appear to be suitable for forensic age diagnostics beyond the 18th year of life. In 2012, Olze et al. investigated the criteria studied by Gustafson using orthopantomograms. The objective of this study was to prove the applicability and reliability of this method with a large cohort and a wide age range, including older individuals. For this purpose, 2346 orthopantomograms of 1167 female and 1179 male Germans aged 15 to 70 years were reviewed. The characteristics of secondary dentin formation, cementum apposition, periodontal recession and attrition were evaluated in all the mandibular premolars. The correlation of the individual characteristics with the chronological age was examined by means of a stepwise multiple regression analysis, in which the chronological age formed the dependent variable. Following those results, R 2 values amounted to 0.73 to 0.8; the standard error of estimate was 6.8 to 8.2 years. Fundamentally, the recommendation for conducting age estimations in the living by these methods can be shared. The values for the quality of the regression are, however, not precise enough for a reliable age estimation around regular retirement date ages. More precise regression formulae for the age group of 15 to 40 years of life are separately presented in this study. Further research should investigate the influence of ethnicity, dietary habits and modern health care on the degenerative characteristics in question.

In order to understand how age, culture, and problems in motor coordination impact the performance of activities of daily living, we used focus groups and in-depth interviews with Australian and Canadian parents to examine activities of daily living of younger (5-7 years of age) and older (8-9 years of age) children with and without DCD. By comparison with their typically developing age group, children with DCD had more difficulty with dressing, personal hygiene, and eating skills. Difficulties with postural control and fine-motor skills were reported to contribute to poorer performance of activities of daily living. As expected, competence in the performance of activities of daily living improved in the older children with and without DCD and there were few differences in the performance of daily living tasks between typical children in Australia and Canada. Overall, the motor difficulties of children with DCD had a significant impact on performance of a wide range of daily activities.

The study of aging processes and the changes in morphological, physiological, and functional characteristics that are associated with aging is of great interest not only for researchers, but also for the general public. The aim of the present paper is to study the biological age and tempos of aging in women older than 60 years, including long-lived females (over 90-years-old), and their associations with morphofunctional characteristics. Somatic traits, body mass components, and functional characteristics were investigated in 119 elderly (between 60 and 74-years-old) and long-lived (over 90-years-old) women in Tiraspol. With the special PC software 'Diagnostics of Aging: BioAge' (National Gerontological Center, Moscow, Russia) the biological age and tempos of aging were evaluated in the study participants. The results show close connections between morphofunctional changes, particularly in body mass components, and biological age. The software demonstrated its validity in the estimation of biological age in the group of elderly women. In the homogenous (according to their chronological age) group of women, three subgroups were separated with different tempos of aging: those with lower rates of aging (biological age less than chronological age by two years or more); those consistent with their chronological age, and those with accelerated tempos of aging (biological age higher than chronological age by two years or more). Morphofunctional characteristics in the studied groups of women demonstrate the trends of age-involutive changes which can be traced through all groups, from those with slow rates of aging, to those with average rates, to those with accelerated tempos of aging, and finally in long-lived women. The results of comparative analysis show that women with accelerated aging are characterized with such traits as lower skeletal muscle mass, lower hand grip strength, and higher metabolic rate.

Background This paper examines age at first drink and adult drinking, binge drinking and DSM-5 alcohol use disorder (AUD) among U.S. Hispanic national groups. Methods Respondents come from two independent studies. The Hispanic Americans Baseline Alcohol Survey used a multistage cluster sample design to interview 5,224 individuals 18 years of age and older selected from the household population in: Miami, New York, Philadelphia, Houston and Los Angeles. Respondents in the border area (N=1,307) constituted a household probability sample of Mexican Americans living on U.S. counties that border Mexico. In both surveys, data were collected during computer assisted interviews conducted in respondents' homes. The HABLAS and the border sample response rates were 76% and 67%, respectively. Results U.S. born Hispanics begin drinking at a younger age than those who are foreign born, independent of national group. Among foreign born Hispanics, age of arrival in the U.S. is not associated with age at first drink. Results support the hypothesis that a younger age at first drink is associated with a higher mean volume of drinking, a higher probability of bingeing and a higher probability of DSM-5 AUD. But the results do not show a clear pattern by which a particular national group would consistently show no associations or stronger associations between age at first drink and the alcohol-related outcomes under consideration. Conclusions An earlier age at first drinking is positively associated with heavier drinking patterns among U.S. Hispanics. However, as in other areas of alcohol epidemiology, here too there is considerable variation in age at first drink and drinking across Hispanic national groups. PMID:24689445

Comparative Biology of Aging

PubMed Central

2009-01-01

Virtually, all research on basic mechanisms of aging has used species that are short lived and thus demonstrably unsuccessful at combating basic aging processes. A novel comparative approach would use a diversity of populations and species, focusing on those with particularly long, healthy lives, seeking the causative mechanisms that distinguish them from shorter lived relatives. Species of interest from this perspective include the naked mole rat, a mouse-size rodent that lives up to 30 years in the laboratory, and the little brown bat, which lives up to 34 years in the wild. Comparisons among dogs of different sizes, which differ by more than 50% in health span might also prove rewarding, as might novel species chosen because of their similarity to humans in certain key traits. Primates, because of their sophisticated cognitive ability, are a group of special value, and small, short-lived primates like the common marmoset might prove especially beneficial. Cell repositories and tissue banks from key species, as well as genomic and analytic tools optimized for comparative studies, would make valuable contributions to a new comparative approach to basic aging research.

BACKGROUND: In a cross-sectional study examining late effects of pediatric sarcoma therapy, long-term survivors were evaluated on their activities of daily living (ADL) performance. PROCEDURE: Thirty-two persons with Ewing sarcoma family of tumors, rhabdomyosarcoma, and non-rhabdomysarcoma-soft tissue sarcoma enrolled an average of 17 years after treatment. Participants were evaluated using the Assessment of Motor and Process Skills (AMPS) [1], a standardized observational evaluation of ADL task performance. Means and 95% confidence intervals for ADL motor and ADL process ability measures were calculated for four groups: 1) sarcoma survivors, 2) “well” adults matched for age and gender, 3) “well” adults matched for gender that were 10 years older; and 4) “well” adults matched for gender that were 20 years older. RESULTS: ADL motor ability was significantly lower for sarcoma survivors than for the age and gender matched comparison group (p<0.05). There was no significant difference between ADL motor ability of sarcoma survivors and the comparison group 10 years older, but sarcoma survivors had significantly better ADL motor ability (p<0.05) than the oldest comparison group (20 years older). Sarcoma survivors had significantly worse ADL process ability than the age matched group (p<0.05). There was no difference in ADL process ability between the sarcoma survivors and comparison groups that were 10 and 20 years older. CONCLUSIONS: This first report of a clinical evaluation of ADL limitation in pediatric sarcoma survivors treated with intensive multimodal cancer therapy suggests that influences on performance of daily life activities are more common than previously reported.

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.

2017-12-01

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.

Stellar Kinematic Groups. II. A Reexamination of the Membership, Activity, and Age of the Ursa Major Group

Utilizing Hipparcos parallaxes, original radial velocities and recent literature values, new Ca II H and K emission measurements, literature-based abundance estimates, and updated photometry (including recent resolved measurements of close doubles), we revisit the Ursa Major moving group membership status of some 220 stars to produce a final clean list of nearly 60 assured members, based on kinematic and photometric criteria. Scatter in the velocity dispersions and H-R diagram is correlated with trial activity-based membership assignments, indicating the usefulness of criteria based on photometric and chromospheric emission to examine membership. Closer inspection, however, shows that activity is considerably more robust at excluding membership, failing to do so only for <=15% of objects, perhaps considerably less. Our UMa members demonstrate nonzero vertex deviation in the Bottlinger diagram, behavior seen in older and recent studies of nearby young disk stars and perhaps related to Galactic spiral structure. Comparison of isochrones and our final UMa group members indicates an age of 500+/-100 Myr, some 200 Myr older than the canonically quoted UMa age. Our UMa kinematic/photometric members' mean chromospheric emission levels, rotational velocities, and scatter therein are indistinguishable from values in the Hyades and smaller than those evinced by members of the younger Pleiades and M34 clusters, suggesting these characteristics decline rapidly with age over 200-500 Myr. None of our UMa members demonstrate inordinately low absolute values of chromospheric emission, but several may show residual fluxes a factor of >=2 below a Hyades-defined lower envelope. If one defines a Maunder-like minimum in a relative sense, then the UMa results may suggest that solar-type stars spend 10% of their entire main-sequence lives in periods of precipitously low activity, which is consistent with estimates from older field stars. As related asides, we note six evolved stars

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

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.

Age-related changes in the social, psychological, and temporal influences on food intake in free-living, healthy, adult humans.

de Castro, John M

2002-06-01

Elderly humans often have a reduction in intake that can produce malnutrition and impaired health. As a result, there is a need to investigate age-related changes in the eating behaviors of free-living humans. To address this issue, 7-day diet diary records that had been collected from 762 paid participants were reanalyzed, separating the participants into four age groups: 20-34 years, 35-49 years, 50-64 years, and 65 years and older. The elderly ate with fewer other people present and earlier in the day than younger people. The elderly were found to be as responsive as younger groups to social facilitation of intake, palatability, cognitive restraint, time of day, day of week, and location, but showed blunted responses to self-reported hunger. There does not appear to be a decline with age in the ability of nonphysiological factors to influence the nutrient intakes of the elderly, but they may not have as great an influence due to lower absolute levels. This suggests that the deficient intakes in the elderly might be corrected or ameliorated by manipulation of nonphysiological factors, such as the number of other people present at meals, the palatability of meals, and the time of day and location of meals.

Intraspecific variation in sociality is thought to reflect a trade-off between current fitness benefits and costs that emerge from individuals' decision to join or leave groups. Since those benefits and costs may be influenced by ecological conditions, ecological variation remains a major, ultimate cause of intraspecific variation in sociality. Intraspecific comparisons of mammalian sociality across populations facing different environmental conditions have not provided a consistent relationship between ecological variation and group-living. Thus, we studied two populations of the communally rearing rodent Octodon degus to determine how co-variation between sociality and ecology supports alternative ecological causes of group living. In particular, we examined how variables linked to predation risk, thermal conditions, burrowing costs, and food availability predicted temporal and population variation in sociality. Our study revealed population and temporal variation in total group size and group composition that covaried with population and yearly differences in ecology. In particular, predation risk and burrowing costs are supported as drivers of this social variation in degus. Thermal differences, food quantity and quality were not significant predictors of social group size. In contrast to between populations, social variation within populations was largely uncoupled from ecological differences. PMID:22344477

Estimation of age in the living: in matters civil and criminal.

Aggrawal, Anil

2009-05-11

Estimation of age is one of the main tasks of a forensic practitioner, especially in third world countries, where many births take place in rural settings without the benefit of the expert supervision of a trained obstetrician. Such births are poorly recorded or more often not recorded at all in terms of exact dates. In many other cases, records are fraudulently falsified for some gain, e.g. to get government jobs or pensions. Developed countries, where ordinarily the birth records are meticulously maintained, are not immune to this problem either. Estimation of the age of living individuals may be needed here for refugees or other persons who arrive without acceptable identification papers. A wide variety of methods are used by the forensic clinician to assess the age of the individual in such cases. This paper discusses and evaluates the most common methods used in India, although the methods can be effectively utilized by medico-legal professionals anywhere in the world.

Fetal and infant growth tends to follow irregular patterns and, particularly in developing countries, these patterns are greatly influenced by unfavorable living conditions and interactions with complications during pregnancy. The aim of this study was to identify groups of children with different risk profiles for growth development. The study sample comprised 496 girls and 508 boys under six months of age from 27 pediatric primary health care units in the city of Rio de Janeiro, Brazil. Data were obtained through interviews with the mothers and by reviewing each child's health card. An unsupervised learning, know as a self-organizing map (SOM) and a K-means algorithm were used for cluster analysis to identify groups of children. Four groups of infants were identified. The first (139) consisted of infants born exclusively by cesarean delivery, and their mothers were exclusively multiparous; the highest prevalences of prematurity and low birthweight, a high prevalence of exclusive breastfeeding and a low proportion of hospitalization were observed for this group. The second (247 infants) and the third (298 infants) groups had the best and worst perinatal and infant health indicators, respectively. The infants of the fourth group (318) were born heavier, had a low prevalence of exclusive breastfeeding, and had a higher rate of hospitalization. Using a SOM, it was possible to identify children with common features, although no differences between groups were found with respect to the adequacy of postnatal weight. Pregnant women and children with characteristics similar to those of group 3 require early intervention and more attention in public policy. Copyright © 2014. Published by Elsevier Ireland Ltd.

The meaning of having to live with cancer in old age.

Little is known about how older people with cancer experience their life situation. To increase the understanding of how illness is experienced in older people with cancer, the aim of this study was to investigate the meaning of living with cancer in old age. The hermeneutic phenomenological method as described by van Manen and referred to as 'phenomenology of praxis' was used. Ten persons (seven women and three men) aged 75 and over, who had a diagnosis of cancer and who had just completed cancer treatment, were interviewed in their own homes. The analysis revealed a life world affected to varying degrees by the cancer disease. The lived experiences across the interviews were revealed in four overarching essential themes: transition into a more or less disintegrated existence, sudden awareness of the finiteness of life, redefinition of one's role in life for good and for bad, meeting disease and illness. To provide individual support and appropriate care to older people with cancer it is important for health care professionals to identify and take care of disabilities and to support the reorientation in the disintegrated life situation. It is also important to have preparedness to meet the old person's thoughts about death. Thus, it is important to encourage the old person to describe her/his illness experience to increase understanding about what is meaningful for her/him.

Socioeconomic factors (SEF) can exert a great impact on food choices. However, limited data are available from the Spanish population. Our aim was to describe the influence of place of residence and habitat size on food group intakes. Data were obtained from the ANIBES study. A 3-day dietary record provided information on food and beverage consumption. Data analysis compared gender, age, Nielsen geographic areas, and habitat population size (urban, semi-urban, and rural). Place of residence did not appear to be a determinant for specific food group consumption during childhood and adolescence, as only higher intakes of non-alcoholic beverages were observed among children aged 9 to 12 years living in the East, when compared to those from the Northwest of Spain ( p < 0.05). Food choices within adults (18 to 64 years) and seniors (65 to 75 years) were conditioned: sugar and sweets intake was significantly higher ( p < 0.05) for adult men living in the Northwest than those from the South, and senior males from North Central areas had significantly higher consumption of eggs ( p < 0.05) compared to the Northeast. Basic food group consumption was only affected during childhood and aging. Adults who inhabited rural areas consumed greater quantities of fats and oils than those from higher population densities ( p < 0.01). Our results indicate that place of residence and habitat size have a limited influence on food choices, regardless of age and gender in the ANIBES study population. It is fundamental to acknowledge that other SEF variables are important and further studies are needed to monitor and assess these influences are warranted.

Background Being diagnosed with human immunodeficiency virus (HIV), and labelled with a chronic, life-threatening, and often stigmatizing disease, can impact on a person's well-being. Psychosocial group interventions aim to improve life-functioning and coping as individuals adjust to the diagnosis. Objectives To examine the effectiveness of psychosocial group interventions for improving the psychological well-being of adults living with HIV/AIDS. Search methods We searched the following electronic databases up to 14 March 2016: the Cochrane Central Register of Controlled Trials (CENTRAL) published in the Cochrane Library (Issue 2, 2016), PubMed (MEDLINE) (1996 to 14 March 2016), Embase (1996 to 14 March 2016), and Clinical Trials.gov. Selection criteria Randomized controlled trials (RCTs) or quasi-RCTs that compared psychosocial group interventions with versus control (standard care or brief educational interventions), with at least three months follow-up post-intervention. We included trials that reported measures of depression, anxiety, stress, or coping using standardized scales. Data collection and analysis Two review authors independently screened abstracts, applied the inclusion criteria, and extracted data. We compared continuous outcomes using mean differences (MD) with 95% confidence intervals (95% CIs), and pooled data using a random-effects model. When the included trials used different measurement scales, we pooled data using standardized mean difference (SMD) values. We reported trials that we could not include in the meta analysis narratively in the text. We assessed the certainty of the evidence using the GRADE approach. Main results We included 16 trials (19 articles) that enrolled 2520 adults living with HIV. All the interventions were multifaceted and included a mix of psychotherapy, relaxation, group support, and education. The included trials were conducted in the USA (12 trials), Canada (one trial), Switzerland (one trial), Uganda (one trial

A qualitative study among women living with HIV assessed the aspects of an evidence-based intervention targeting HIV transmission risk reduction (Women Involved in Life Learning from Other Women [WiLLOW]) that women valued and how their lives were impacted. Thirty-one women (80.6% African American) completed interviews. Women valued the personal stories and positive group dynamics (i.e. safety, trust, openness, getting feedback, bonding, and socializing). As a result of WiLLOW, women embraced a strong woman image, joined groups, changed behaviors, accepted their HIV status, became optimistic, and spoke up/advocated in their relationships and communities. Interventions for HIV-positive women may benefit from incorporating the sharing of stories in their curricula and factors that build positive group dynamics.

To describe the dynamics of development along the early years of life among children living under unfavorable socioeconomic conditions. In 5401 children younger than 6 years old living in Florencio Varela and in the Matanza-Riachuelo River Basin (Matanza, Villa 21-24, Wilde, Villa Inflamable and Acuba), areas with a high proportion of families with unmet basic needs, a logistic regression analysis was used to estimate the median age at attainment of 13 psychomotor developmental milestones; differences between these ages and median age at attainment of milestones as per the national reference were plotted on the y-axis, while the median age as per the national reference was plotted on the x-axis. Three stages were observed: the first one between 0 and 270 days with normal development, in which the median age at attainment was similar to that of the national reference; a second one of progressive development delay; and a third one of recovery at 1260 days. Adjusted linear spline slopes were 0.06 (not significant), -0.26 (p < 0.0001) and 0.26 (p < 0.01) for stages 1, 2 and 3, respectively. The three slopes were statistically different from each other. The stage of normal development (stage 1) was attributed to the protective effect of the mother and the family environment; stage 2 of progressive delay, to the unfavorable impact of the environment, and stage 3 of partial recovery was attributed to attending a daycare center. These findings allow the implementation of effective interventions at each stage. Three periods with different developmental tempos were identified. Sociedad Argentina de Pediatría.

Data on the prevalence of chronic conditions, their risk factors, and their associations with disability in older people living with and without HIV are scarce in sub-Saharan Africa. In older people living with and without HIV in sub-Saharan Africa: 1) to describe the prevalence of chronic conditions and their risk factors and 2) to draw attention to associations between chronic conditions and disability. Cross-sectional individual-level survey data from people aged 50 years and over living with and without HIV were analyzed from three study sites in Uganda. Diagnoses of chronic conditions were made through self-report, and disability was determined using the WHO Disability Assessment Schedule (WHODAS). We used ordered logistic regression and calculated predicted probabilities to show differences in the prevalence of multiple chronic conditions across HIV status, age groups, and locality. We used linear regression to determine associations between chronic conditions and the WHODAS. In total, 471 participants were surveyed; about half the respondents were living with HIV. The prevalence of chronic obstructive pulmonary disease and eye problems (except for those aged 60-69 years) was higher in the HIV-positive participants and increased with age. The prevalence of diabetes and angina was higher in HIV-negative participants. The odds of having one or more compared with no chronic conditions were higher in women (OR 1.6, 95% CI 1.1-2.3) and in those aged 70 years and above (OR 2.1, 95% CI 1.2-3.6). Sleep problems (coefficient 14.2, 95% CI 7.3-21.0) and depression (coefficient 9.4, 95% CI 1.2-17.0) were strongly associated with higher disability scores. Chronic conditions are common in older adults and affect their functioning. Many of these conditions are not currently addressed by health services in Uganda. There is a need to revise health care policy and practice in Uganda to consider the health needs of older people, particularly as the numbers of people living into

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.

Background There should be a substantial increase in the intake of dietary energy, protein and other nutrients by lactating women, though these special increments can be different in different ethnic groups. Objective To evaluate the influence of maternal ethnicity and diet on the quality of breast milk and its potential effect on early childhood development. Design A total of 185 mothers (150 Native and 35 Russian) living in settlements and small towns of rural Yakutia and 54 mothers (26 Native and 28 Russian) living in Yakutsk were surveyed and average food intake was recorded during 3 successive days before the survey was analyzed. Results The amount of protein varied from 18 to 168.3 g/day, fat – from 12 to 176.1 g/day, energy – from 900 to 3680.4 kcal/day. Protein intake was at the level of current recommended dietary allowances (RDA) in Russians and was higher than in Natives living in rural settlements and small towns (p=0.02) and in Yakutsk (p=0.03). Carbohydrate intake was higher, though not significantly, in both ethnic groups compared with the current recommendations. Protein, fat, carbohydrates and, therefore, energy intake were lower (p<0.03) in Native women living in Yakutsk compared with the intake of Native women living in rural settlements and small towns. Conclusions The dietary intakes of energy and macronutrients depended on the place where a woman lived rather than on her ethnicity. Overall, energy intake was considered to be at the lower limit (basal energy expenditure 2002/2005) for lactating women, with the exception of Native women living in Yakutsk whose energy intake was below the lower limit.

To explore the activities of daily living and psychological well-being of older people living in nursing homes and also to examine the effectiveness of a gardening programme in enhancing socilaisation and life satisfaction, reducing loneliness and promoting activities of daily living for older people living in nursing homes. Life in nursing homes can mean very limited physical and social activity, leading to further decline in function for many older people. This was a quasi-experimental pre and posttest control group design. Older people from nursing homes were invited to join the eight week indoor gardening programme (experimental group), while older people in other nursing homes were treated as the control group; they received regular care without the eight week indoor gardening programme. There were 26 older people (25 female and one male; mean age 85 years) in the experimental group and 27 (20 female and seven male; mean age 82 years) in the control group. Demographic data including age, gender, educational level and financial situation were collected, in addition to information regarding life satisfaction, loneliness, physical activity and social network situation, before and after the eight week indoor gardening programme for both the experimental and control groups. Also, details of experimental group subjects' experience of the indoor gardening programme were elicited using open-ended questions. There were significant improvements in life satisfaction and social network and a significant decrease in perception of loneliness for older people in the experimental group after the eight week indoor gardening programme, while the activities of daily living were unchanged for both groups after the programme. Given the positive effects of gardening activities, it is suggested that they be promoted more widely among nursing home residents.

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.

HIV infection has been historically considered a disease of young adults; however, adults aged 50 years and older represent now an increasing proportion of HIV cases worldwide, including in Portugal. In this context, given the considerable burden associated with living with HIV, the topic of quality-of-life (QoL) assessment has become increasingly relevant. The aims of this study were to examine the age-related differences in QoL and depressive symptoms of younger and middle-aged and older adults with HIV as well as the sociodemographic, HIV-related and depressive symptoms (cognitive-affective and somatic) associated with QoL domains. The sample consisted of 1194 HIV-infected patients, recruited from 10 Portuguese hospitals. QoL data were collected using the WHOQOL-HIV-Bref questionnaire. Patients also completed the Beck Depression Inventory. Of the 1194 patients, 185 (15.5%) were over 50 years old. Middle-aged and older patients reported significantly lower QoL in the physical, independence and social relationships domains. Regarding the specific facets of QoL, middle-aged and older patients reported significantly lower scores in seven of the 29 specific facets of the WHOQOL-HIV-Bref and higher scores in one facet (financial resources). Overall, among middle-aged and older patients, higher education, being employed, a shorter time since HIV diagnosis, use of combination anti-retroviral therapy and fewer depressive symptoms were significantly associated with higher QoL ratings. Our findings suggest that both cognitive-affective and somatic depressive symptoms account for significant variability in QoL scores in middle-aged and older patients. Because an important feature of healthy ageing is maintaining QoL, these data may provide useful information for tailoring age-appropriate and effective interventions to improve the mental health and QoL of middle-aged and older patients living with HIV.

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.

Bibliotherapy is a supplement, simple, inexpensive and readily available method to treat the diseases that is performed with cooperation of librarians and psychologists or doctors. The aim of this study is the investigation of group bibliotherapy's effect on the self-esteem of the female students of Isfahan University of Medical Sciences Living in Dormitory in 2012. The present study is an interventional semi-experimental study with pre test and post test and control group. The statistical population of study consisted of 32 female students who reside in Isfahan University of Medical Sciences dormitories which control and case groups and the students were divided randomly between these two groups. Data was collected by Cooper Smith Self-esteem questionnaire scale (Cronbach's alpha: 0.85). Two groups were examined by the questionnaire in pre test. Case group received group bibliotherapy for 2 month (8 sessions of 2 hours), while the control group received no training at all. Then, 2 groups were assessed in post test after 1 month. Descriptive statistics (means and frequencies distribution) and inferential statistics (independent t- test, paired t- test and mann whitney) were used and data was analyzed by SPSS20 software. The findings showed that group bibliotherapy had positive and significant effect on general, family, professional and total self esteem of female students living in dormitories, but it had no effect on their social self esteem. Group bibliotherapy can increase female students' self-esteem levels. On the other hand, conducting these studies not only can improve mental health of people, but can also improve their reading habits.

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.

Effects of living without siblings and living with grandparents on overweight and obesity may change with child’s age. We aimed to examine these effects from early childhood to school age at the national level in Japan. Subjects were 43,046 children born in Japan during two weeks in 2001 who were followed annually from 2.5 to 13 years of age in the Longitudinal Survey of Newborns in the 21st Century. We used measured body height and weight reported by participants at each survey and followed the criteria of the International Obesity Task Force to define overweight and obesity. Random-effects logit models by sex, adjusted for time-varying and time-invariant covariates, assessed odds ratios of overweight and obesity for living without siblings and for living with grandparents at each age. The likelihood of overweight and obesity was significantly higher at 8 years and older among children living without siblings, compared with those living with siblings, and odds ratios were highest at 11 years of age in boys (1.87, 95% confidence interval [CI]: 1.49, 2.33) and at 10 and 13 years of age in girls (1.75 [95% CI: 1.36, 2.23] and 1.73 [95% CI: 1.30, 2.31], respectively). It was also significantly higher at 5.5 years and older among children living with grandparents, compared with those living without grandparents, and odds ratios were highest at 10 and 13 years of age in boys (1.53 [95% CI: 1.30, 1.80] and 1.54 [95% CI: 1.27, 1.86], respectively) and at 11 years of age in girls (1.51, 95% CI: 1.24, 1.84). In Japan, living without siblings and living with grandparents may increase the likelihood of overweight and obesity at 8 and 5.5 years and older, respectively. Child’s age should be considered during formulation of strategies for prevention of overweight and obesity in these groups. PMID:28414810

2008-03-01

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.

A radiographic assessment of third molar development is essential for differentiating between juveniles and adolescents in forensic age estimations. As the developmental stages of third molars are highly correlated, age estimates based on a combination of a full set of third molar scores are statistically complicated. Transition analysis (TA) is a statistical method developed for estimating age at death in skeletons, which combines several correlated developmental traits into one age estimate including a 95% prediction interval. The aim of this study was to evaluate the performance of TA in the living on a full set of third molar scores. A cross sectional sample of 854 panoramic radiographs, homogenously distributed by sex and age (15.0-24.0 years), were randomly split in two; a reference sample for obtaining age estimates including a 95% prediction interval according to TA; and a validation sample to test the age estimates against actual age. The mean inaccuracy of the age estimates was 1.82 years (±1.35) in males and 1.81 years (±1.44) in females. The mean bias was 0.55 years (±2.20) in males and 0.31 years (±2.30) in females. Of the actual ages, 93.7% of the males and 95.9% of the females (validation sample) fell within the 95% prediction interval. Moreover, at a sensitivity and specificity of 0.824 and 0.937 in males and 0.814 and 0.827 in females, TA performs well in differentiating between being a minor as opposed to an adult. Although accuracy does not outperform other methods, TA provides unbiased age estimates which minimize the risk of wrongly estimating minors as adults. Furthermore, when corrected ad hoc, TA produces appropriate prediction intervals. As TA allows expansion with additional traits, i.e. stages of development of the left hand-wrist and the clavicle, it has a great potential for future more accurate and reproducible age estimates, including an estimated probability of having attained the legal age limit of 18 years.

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.

Attention processes were studied using a model based on visual searches for a specified element in grids of size 3 x 3 and 7 x 7 cm displayed on a monitor screen. 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.

Introduction: Bibliotherapy is a supplement, simple, inexpensive and readily available method to treat the diseases that is performed with cooperation of librarians and psychologists or doctors. The aim of this study is the investigation of group bibliotherapy's effect on the self-esteem of the female students of Isfahan University of Medical Sciences Living in Dormitory in 2012. Materials and Methods: The present study is an interventional semi-experimental study with pre test and post test and control group. The statistical population of study consisted of 32 female students who reside in Isfahan University of Medical Sciences dormitories which control and case groups and the students were divided randomly between these two groups. Data was collected by Cooper Smith Self-esteem questionnaire scale (Cronbach's alpha: 0.85). Two groups were examined by the questionnaire in pre test. Case group received group bibliotherapy for 2 month (8 sessions of 2 hours), while the control group received no training at all. Then, 2 groups were assessed in post test after 1 month. Descriptive statistics (means and frequencies distribution) and inferential statistics (independent t- test, paired t- test and mann whitney) were used and data was analyzed by SPSS20 software. Results: The findings showed that group bibliotherapy had positive and significant effect on general, family, professional and total self esteem of female students living in dormitories, but it had no effect on their social self esteem. Conclusion: Group bibliotherapy can increase female students’ self-esteem levels. On the other hand, conducting these studies not only can improve mental health of people, but can also improve their reading habits. PMID:25250355

Internet of Things (IoT) devices are rapidly penetrating e-health and assisted living domains, and an increasing proportion among them goes on the account of computationally-weak devices, where security and privacy provisioning alone are demanding tasks, not to mention grouping proofs. This paper, therefore, gives an extensive analysis of such proofs and states lessons learnt to avoid possible pitfalls in future designs. It sticks with prudent engineering techniques in this field and deploys in a novel way the so called non-deterministic principle to provide not only grouping proofs, but (among other) also privacy. The developed solution is analyzed by means of a tangible metric and it is shown to be lightweight, and formally for security.

We hypothesized that recent hands-on practice for cardiopulmonary resuscitation (CPR) would be strongly associated with a higher likelihood of self-efficacy in bystander CPR among laypersons according to age and gender group. We used the National Korean Community Health Survey database of 228921 representatively sampled responders from 253 counties in 2012. Laypersons who had previous CPR training were eligible. Exposure variables were having had CPR training with hands-on practice session with a manikin (Practical-CPR-Training) and CPR training within the last 2 years (Recent-CPR-Training). Primary outcome was self-efficacy in bystander CPR. Multivariable logistic regression analysis was performed. The final model with an interaction term was evaluated to compare the effects of CPR training across different age and gender groups. Of 62425 eligible respondents who have had CPR training, 20213 (32.4%) had Practical-CPR-Training. Adjusted odds ratios (AORs) for self-efficacy were 4.08 (3.78-4.41) in Practical-CPR-Training, 2.61 (2.50-2.73) in male, 1.26 (1.16-1.36) in good self-rated health, 1.19 (1.10-1.29) in high school graduate, 1.19 (1.01-1.39) in persons living with stroke patients in household, and 1.17 (1.10-1.24) in Recent-CPR-Training. In interaction models, Practical-CPR-Training showed higher self-efficacy in all age and gender groups, whereas Recent-CPR-Training was not associated with better self-efficacy in elderly group, male (AOR, 0.90 [0.69-1.18]) and female (AOR, 0.94 [0.72-1.23]). Self-efficacy in bystander CPR was higher in person with recent CPR training with hands-on practice with a manikin. Copyright © 2015 Elsevier Inc. All rights reserved.

Background Tobacco smoking (TS) and illicit drug use (IDU) are of public health concerns especially in developing countries, including Bangladesh. This paper aims to (i) identify the determinants of TS and IDU, and (ii) examine the association of TS with IDU among young slum dwellers in Bangladesh. Methodology/Principal Findings Data on a total of 1,576 young slum dwellers aged 15–24 years were extracted for analysis from the 2006 Urban Health Survey (UHS), which covered a nationally representative sample of 13,819 adult men aged 15–59 years from slums, non-slums and district municipalities of six administrative regions in Bangladesh. Methods used include frequency run, Chi-square test of association and multivariable logistic regression. The overall prevalence of TS in the target group was 42.3%, of which 41.4% smoked cigarettes and 3.1% smoked bidis. The regression model for TS showed that age, marital status, education, duration of living in slums, and those with sexually transmitted infections were significantly (p<0.001 to p<0.05) associated with TS. The overall prevalence of IDU was 9.1%, dominated by those who had drug injections (3.2%), and smoked ganja (2.8%) and tari (1.6%). In the regression model for IDU, the significant (p<0.01 to p<0.10) predictors were education, duration of living in slums, and whether infected by sexually transmitted diseases. The multivariable logistic regression (controlling for other variables) revealed significantly (p<0.001) higher likelihood of IDU (OR = 9.59, 95% CI = 5.81–15.82) among users of any form of TS. The likelihood of IDU increased significantly (p<0.001) with increased use of cigarettes. Conclusions/Significance Certain groups of youth are more vulnerable to TS and IDU. Therefore, tobacco and drug control efforts should target these groups to reduce the consequences of risky lifestyles through information, education and communication (IEC) programs. PMID:23935885

Hospitalized patients with acute poisoning come from all classes of society. The relationship between living conditions and pattern of poisoning is, however, unclear. The aim of this study was to examine the connection between living conditions in Oslo and the pattern of acute poisonings, measured by incidence, main toxic agents and intention. A one-year multi-centre study with prospective inclusion of all patients ≥ 18 years of age with a registered address in Oslo admitted to an Oslo hospital with acute poisoning from 1 April 2003 through 31 March 2004. The 15 city districts were grouped into three, according to the official living conditions index in Oslo: city district group 1 (best living conditions), city district group 2 (average living conditions) and city district group 3 (most difficult living conditions). Of a total of 947 patients admitted with acute poisoning as their main diagnosis in the study period, 691 were included in the study, 660 of whom had self-inflicted poisoning. In city district group 3, the annual incidence of acute poisonings was 2.14 per 1000 inhabitants, significantly higher than city district group 2, with 1.50 (p < 0.001), and city district group 1, with 1.36 (p < 0.001). Measured as intention assessed by the treating physician, suicidal and drug related poisonings and those induced by a "cry for help" were more common in city district group 3 (0.74, 0.59 and 0.74 per 1000 inhabitants, respectively) than in city district group 2 (0.62, 0.40 and 0.41, respectively) and city district group 1 (0.52, 0.32 and 0.45, respectively). The main toxic agents were predominantly benzodiazepines (20 %), ethanol (18 %) and paracetamol (12 %). There were no statistically significant differences in the distribution of main toxic agents between the city district groups. The findings show a social gradient, with the highest incidence of poisonings in the city district group with the most difficult living conditions.

Menstrual migraine is a highly prevalent disorder among adult women, resulting in disability and loss of quality of life. Some studies have reported menstrual cycle synchrony among women living together. No study has reported whether there may also be a higher prevalence of menstrual migraine among these women. Thus, they reported here the prevalence of menstrual migraine in a group of women living together compared with a control group of women living alone, and discussed the possible factors involved. The study was conducted on female university students aged 18-30 years with a diagnosis of migraine according to the criteria of the International Classification of Headache Disorders III, beta appendix criteria. The subjects were divided into a group of women who lived together with two or more other students and a control group of age-matched students who lived alone, interviewed with a specific questionnaire and assessed for 3 months by means of a paper pain diary. The data evaluated included frequency of headache, presence of menstrual migraine, intensity of headache, medications used including contraceptives, and triggering factors such as diet, sleep deprivation, and stress. The menstrual data and data related to migraine were also investigated in the roommates. A higher occurrence of menstrual migraine among women living together (9, 50%) compared with women living alone (3, 16.7%) (P = .03) was detected. After binary logistic regression analysis, this finding was not related to the main influencing factors detected, that is, use of a contraceptive, test stress, or sleep deprivation (P = .03, adjusted odds ratio: 7.87; 1.23-50.36). These women also showed menstrual cycle synchrony with their roommates (8, 44.4%) and the presence of headache crises during the menstruation of their colleagues (11, 61.1%). The present study detected a higher occurrence of menstrual migraine among women who lived together. Since there was no previous description of this

Background Japanese encephalitis (JE) is very prevalent in China, but the incidence of JE among children has been greatly reduced by extensive promotion of vaccinations. The incidence of JE among adults, however, has increased in some parts of China. Methods/Principal Findings Data on JE in mainland China, in terms of incidence, gender, and age, were collected between 2004 and 2014. We conducted spatial and temporal analyses on data from different age groups. Generally, children aged 0–15 years still represent the major population of JE cases in China, despite the gradual decrease in incidence over years. However, the incidence of JE among adults in several provinces is notably higher than the national average, especially during the epidemic waves in 2006, 2009, and 2013. The JE cases in the 0–15-year-old group are distributed mainly in the area south of the Yangtze River, with peak incidence occurring from July to September. In the adult group, especially for those over 40 years old, the JE cases are concentrated mainly in the area north of the Yangtze River. JE incidence in the adult group in September and October is significantly greater compared to the other groups. Further analysis using Local Indicators of Spatial Association (LISA) reveals that the distribution of adult JE cases in the six provinces north of the Yangtze River, between north 30–35° latitude and east 110–130° longitude, is a hotspot for adult JE cases. Conclusions/Significance The rate of JE case increase for adults is much greater than for children and has become a public health issue. Therefore, studies on the necessity and feasibility of vaccinating adults who live in JE-endemic areas, but have never been vaccinated for JE, should become a new focus of JE prevention in the future.

Tenenbaum, Harriet R; Hohenstein, Jill M

2016-10-01

This study examined relations between 124 British children's and their parents' endorsements about the origins of three living things (human, non-human animal, and plant) as reported on questionnaires. In addition to completing questionnaires, half of the sample discussed the origins of entities (n=64) in parent-child dyads before completing the questionnaires. The 7-year-old age group endorsed creationism more than evolution, and the 10-year-old age group endorsed both concepts equally for all three living things. Children's endorsements were correlated with their parents' endorsements for all three living things. Children's endorsement of evolutionary theory was more closely related to parent-child conversational mentions of evolution than to parents' endorsement of evolutionary theory in questionnaires. A similar pattern was found for children's endorsement of creationism. Parent-child conversations did not consistently invoke evolution or creationism even when parents endorsed a particular theory. Findings are interpreted in relation to the pivotal role of joint collaborative conversation in children's appropriation of scientific content. Copyright © 2016 Elsevier Inc. All rights reserved.

The aim was to examine the effect of tailored nutritional guidance on nutrition, health-related quality of life (HRQoL) and falls in persons with Alzheimer disease (AD). Randomised controlled trial. Persons with AD living with a spouse. Tailored nutritional guidance with home visits during one year. The control group received a written guide about nutrition in older adults and all community-provided normal care. The primary outcome measure was weight change, and secondary outcomes included changes in protein and micronutrient intakes from three-day food records, HRQoL (15D) and rate of falls. Of the participants (n = 78) with AD (mean age 77.4, 69% males), 40% were at risk for malnutrition, 77% received < 1.2 g/bodyweight (kg) of protein at baseline. We found no difference in weight change between the groups. At 12 months, the mean change in protein intake was 0.05 g/bodyweight (kg) (95% CI -0.06 to 0.15) in the intervention group (IG), and -0.06 g/kg (95% CI -0.12 to 0.02) in the control group (CG) (p = 0.031, adjusted for baseline value, age, sex, MMSE and BMI). Participants' HRQoL improved by 0.006 (95% CI -0.016 to 0.028) in the IG, but declined by -0.036 (95% CI -0.059 to 0.013) in the CG (p = 0.007, adjusted for baseline value, age, sex, MMSE and BMI). Dimensions that differed included mental functioning, breathing, usual activities and depression. The fall rate was 0.55 falls/person per year (95% CI 0.34 to 0.83) in the IG, and 1.39 falls/person per year (95% CI 1.04 to 1.82) in the CG (IRR 0.55; 95% CI 2.16 to 6.46; p < 0.001 adjusted for age, sex and MMSE). Tailored nutritional guidance improves nutrition and HRQoL, and may prevent falls among AD people living with a spouse.

Background Non‐married persons are known to have poor mental health compared with married persons. Health differences between marital status groups may largely arise from corresponding differences in interpersonal social bonds. However, official marital status mirrors the social reality of persons to a decreasing extent, and living arrangements may be a better measure of social bonds. Little is known about mental health in different living arrangement groups. This study aims to establish the extent and determinants of mental health differences by living arrangement in terms of psychological distress (GHQ) and DSM‐IV psychiatric disorders (CIDI). Methods Data were used from the nationally representative cross sectional health 2000 survey, conducted in 2000–1 in Finland. Altogether 4685 participants (80%) aged 30–64 years were included in these analyses; comprehensive information was available on measures of mental health and living arrangements. Living arrangements were measured as follows: married, cohabiting, living with other(s) than a partner, and living alone. Results Compared with the married, persons living alone and those living with other(s) than a partner were approximately twice as likely to have anxiety or depressive disorders. Cohabiters did not differ from the married. In men, psychological distress was similarly associated with living arrangements. Unemployment, lack of social support, and alcohol consumption attenuated the excess psychological distress and psychiatric morbidity of persons living alone and of those living with other(s) than a partner by about 10%–50% each. Conclusions Living arrangements are strongly associated with mental health, particularly among men. Information on living arrangements, social support, unemployment, and alcohol use may facilitate early stage recognition of poor mental health in primary health care. PMID:16698975

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

Caprine coccidiosis, affecting mainly young goat kids around the weaning period, is worldwide the most important disease in the goat industry. Control of caprine coccidiosis is increasingly hampered by resistances developed against coccidiostatic drugs leading to an enhanced need for anticoccidial vaccines. In the current study we conducted an oral immunization trial with live attenuated sporulated Eimeria ninakohlyakimovae oocysts. Sporulated E. ninakohlyakimovae oocysts were attenuated by X-irradiation technique. The experimental design included a total of 18 goat kids divided into the following groups: (i) animals immunized with attenuated E. ninakohlyakimovae oocysts at 5 weeks of age and challenged 3 weeks later with non-irradiated homologous oocysts (group 1); (ii) animals infected with non-attenuated E. ninakohlyakimovae oocysts at 5 weeks of age and challenged 3 weeks later with non-attenuated homologous oocysts (group 2); (iii) animals primary-infected with untreated E. ninakohlyakimovae oocysts at 8 weeks of age (control of the challenge infection, group 3); (iv) non-infected control animals (group 4). Goat kids immunized with live attenuated E. ninakohlyakimovae oocysts (group 1) excreted significantly less oocysts in the faeces (95.3% reduction) than kids infected with non-attenuated ones (group 2). Furthermore, immunization with live but attenuated oocysts resulted in ameliorated clinical coccidiosis compared to goat kids infected with untreated oocysts (group 2) and resulted in equally reduced signs of coccidiosis after challenge infection compared to acquired immunity driven by non-attenuated oocysts. Overall, the present study demonstrates for the first time that live attenuated E. ninakohlyakimovae oocysts orally administered showed almost no pathogenicity but enough immunogenicity in terms of immunoprotection. Importantly, vaccinated animals still shed low amounts of oocysts, guaranteeing environmental contamination and consecutive booster

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

The aim of this study was to explore the social networks of older adults living with HIV. Interviews were conducted with nine individuals aged 50 or older living with HIV in Helsinki, Finland. Analysis of transcripts was analysed by inductive qualitative content analysis. Results indicated that these participants' networks tended to be large, including those both aware and unaware of the participants' health status. Analysis identified three main themes: large multifaceted social networks, importance of a support group, and downsizing of social networks. Support received appeared to be of great importance in coping with their health condition, especially since the time of diagnosis. Friends and family were the primary source of informal support. The majority of participants relied mostly on friends, some of whom were HIV-positive. Formal support came primarily from the HIV organisation's support group. In this study group, non-disclosure did not impact participants' well-being. In years to come, social networks of older adults living with HIV may shrink due to personal reasons other than HIV-disclosure. What is of primary importance is that healthcare professionals become knowledgeable about psychosocial issues of older adults living with HIV, identifying latent problems and developing adequate interventions in the early stages of the disease; this would help prevent social isolation and foster successful ageing with HIV.

Internet of Things (IoT) devices are rapidly penetrating e-health and assisted living domains, and an increasing proportion among them goes on the account of computationally-weak devices, where security and privacy provisioning alone are demanding tasks, not to mention grouping proofs. This paper, therefore, gives an extensive analysis of such proofs and states lessons learnt to avoid possible pitfalls in future designs. It sticks with prudent engineering techniques in this field and deploys in a novel way the so called non-deterministic principle to provide not only grouping proofs, but (among other) also privacy. The developed solution is analyzed by means of a tangible metric and it is shown to be lightweight, and formally for security. PMID:26729131

[Purpose] This study was carried out to examine the effect of the application of group exercise program composed to induce interests and assertive participation of adults with cerebral palsy on the self-efficacy and activities of daily living, as well as to provide basic clinical data that are effective and trustworthy in enhancing the physical and emotional interaction in the future. [Subjects and Methods] Those among the 23 adult with cerebral palsy who are the subjects of research and able to participate only in the evaluation of measurement tools prior to and after the experiment were allocated to the control group while only those who can participate in the group exercise program implemented over 12 sessions were allocated to the experimental group. For the control group, a range of motion of joint exercise and stretching exercise were executed on the arms, legs and trunk, while for the experimental group, group exercise that is implemented with participation of several subjects simultaneously was executed 2 times a week with 40 minutes for each session over a period of 6 weeks for the total of 12 sessions. [Results] In both the experimental group and the control group, there were statistically significant changes in the average scores of self-efficacy and activities of daily living after the exercise in comparison to that prior to the exercise. Moreover, there were statistically significant differences in self-efficacy and activities of daily living in terms of quantity of change prior to and after the exercise between the two groups. [Conclusion] Therefore, group exercise program composed to induce physical and emotional interaction, and active participation of adults with cerebral palsy can be considered as an effective intervention method in improving their self-efficacy and activities of daily living.

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

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

Breathing vitally serves body homeostasis. The prevalence of upper airway infections is often taken as an indicator of overall health status of a population living at a given time. In the present study we examined the unearthed remains of skulls from the XIII-XV century inhabitants searching for signs of maxillary sinusitis. Maxillary sinuses of the skulls of 92 individuals were inspected macroscopically and, if necessary, endoscopically. Osseous changes, including the pitting and abnormal spicule formation were present in 69 cases (75.0 %). It was found that, overall, dental infection was a major cause of maxillary sinusitis (18.8 %). Severe bone changes were observed in the adults' skulls, but were also present in the sinus walls of children's skulls. Post-inflammatory changes were manifest as remodeling and damage to the sinus walls. The results indicate that both children and adults of the Middle Ages suffered from chronic sinusitis. These observations confirm that the climate, environment, and lifestyle of the medieval populations contributed to the morbidity of the upper respiratory tract.

Aging and efficiency in living systems: Complexity, adaptation and self-organization.

Living systems are open, out-of-equilibrium thermodynamic entities, that maintain order by locally reducing their entropy. Aging is a process by which these systems gradually lose their ability to maintain their out-of-equilibrium state, as measured by their free-energy rate density, and hence, their order. Thus, the process of aging reduces the efficiency of those systems, making them fragile and less adaptive to the environmental fluctuations, gradually driving them towards the state of thermodynamic equilibrium. In this paper, we discuss the various metrics that can be used to understand the process of aging from a complexity science perspective. Among all the metrics that we propose, action efficiency, is observed to be of key interest as it can be used to quantify order and self-organization in any physical system. Based upon our arguments, we present the dependency of other metrics on the action efficiency of a system, and also argue as to how each of the metrics, influences all the other system variables. In order to support our claims, we draw parallels between technological progress and biological growth. Such parallels are used to support the universal applicability of the metrics and the methodology presented in this paper. Therefore, the results and the arguments presented in this paper throw light on the finer nuances of the science of aging. Copyright © 2017 Elsevier B.V. All rights reserved.

The purpose of this study was to understand the diet, drinking, and smoking behaviors of university students and to analyze the health behaviors that could be a risk factor for non-communicable diseases (NCDs) in order to contribute to the promotion of NCD prevention in youth. The survey was carried out using a questionnaire with closed questions including items about health behaviors. The subjects surveyed were students of 10 universities on the main island of Japan (1,196 valid responders). The score for the nutritional balance was significantly low in the group living alone for both students in their teens and 20s. For the frequency of not eating breakfast, results suggest that living alone and increase in age are related to the lack of breakfast for both males and females. Teenage males living alone tended to lack in consideration for the intake of animal fat than those not living alone. The females showed a higher tendency to eat sweets and snacks during the day than the males. For the males who living alone, results suggest that they tended to have a higher or equal alcohol intake to females in their 20s and males in their 20s not living alone even when they are underage. Males in their 20s tended to have a higher amount and frequency of smoking than other groups regardless of their living arrangement. Accumulation of health behavior that could be a risk for NCDs was found in some of the groups, such as males living alone.

Very little is known about socioeconomic differentials in mortality among persons surviving to old age in sub-Saharan Africa. We report on the impact of low socioeconomic position (SEP) on mortality over a 5-year observation period among community-dwelling older adults living in southwestern Nigeria. Data are from a household multistage probability sample of 2,149 Yoruba Nigerians aged 65 years or older. We collected information on indices related to health and well-being at baseline (2003/2004). Socioeconomic positions were estimated using asset-based measures relevant to low income settings. Information on mortality was obtained by research supervisors in multiple waves (2007, 2008, and 2009). Associations between baseline covariates and mortality were explored using discrete time survival models and life tables. We recorded 357 deaths over 5 years, or an annual mortality rate of 4.7% (95% CI = 4.2-5.2). Being 80 years or older (HR = 1.6, 95% CI = 1.1-2.5) and belonging to the lowest SEP (HR = 1.5, 95% CI = 1.1-2.1) were the main predictors of mortality. The significant effect of lowest SEP on mortality risk over the study period was independent of age, gender, education, rural or urban residence, weight, physical activity level, and social engagement. In this sample of older persons living in an economically disadvantaged context, we found persistent socioeconomic differentials in mortality estimated, conservatively, over 5 years. © The Author 2016.

Deceased donor organ shortage has made living donors (LD) major source for renal transplantation (RTx) in India. Spouses represent an important source of allograft. We carried out a retrospective study of spousal RTx vs. other LDRTx to compare long-term results. This retrospective single-center study was undertaken to evaluate demographic, patient survival, graft survival, function vis-à-vis serum creatinine (SCr) and rejection episodes in 1523 living donor renal allograft recipients from 1998 to 2009. It included spouse donors (n=337) (group 1), living related donors (LRD) (n=969) (group 2), and living unrelated donors (LUD) (n=217) (group 3). Mean recipient age (years +/- SD)) was 41.48 +/- 8.87, 30.49 +/- 10.61, and 37.13 +/- 13.25, respectively for the three groups who were followed for 4.47 +/- 3.03, 4.47 +/- 3.0 and 5.15 +/- 3.28 years respectively. Female donors were 92.6%, 66.4%, and 41%, mean HLA match was 1.15 +/- 0.93, 3 +/- 1.05 and 1.30 +/- 1.08 respectively. One, 5 and 12 year graft survivals among group 1 were 91.39%, 75.49%, and 73.13%; 90.98%, 74.10% and 64.57% in group 2 and 94.92%, 82.86% and 70.31% in group 3. Patient survival for 1, 5 and 12 years were 89.31%, 72.55% and 66.58% in group 1, 93.57%, 82.25% and 72.23% in group 2, and 92.62%, 79.76% and 66.79% in group 3. Acute rejections were noted in 16.6%, 15.8% and 17% respectively. In circumstances of organ shortage andunavailability of well developed ABO incompatible transplants, spousal donation is viable option.

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.

Trofimova, Irina; Christiansen, Julie

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.

The aim of this study was to calculate assisted reproductive technology (ART) success rates for fresh autologous and donor cycles in women aged > or = 45 and the resultant cost per live birth. We performed a retrospective population-based study of 2339 ART cycles conducted in Australia, 2002-2004 to women aged > or = 45 years. The cost-outcome study was performed on fresh autologous treatment cycles. There were 1101 fresh autologous cycles initiated in women aged > or = 45, with a pregnancy rate of 1.9 per 100 initiated cycles. There were 21 women who achieved a clinical pregnancy with 15 (71%) ending in early pregnancy loss and 6 in live singleton births. The live birth rate following fresh autologous initiated cycles was 0.5% [95% confidence interval (CI): 0.1-1.0%]. Fresh donor recipients had an higher live birth rate of 19.1% (95% CI: 15.1-23.2) (odds ratio 43.2; 95% CI: 18.6-100.3) compared with women having fresh autologous cycles. The average cost of a live birth following fresh autologous cycles was 753,107 euros. The success rate of fresh autologous treatment for women aged > or = 45 years was < 1%. The very high cost of a live birth reflects a treatment failure rate of > 99%. The ART profession should counsel patients of the reality of the technology before the patients consent to treatment.

Social Familiarity Reduces Reaction Times and Enhances Survival of Group-Living Predatory Mites under the Risk of Predation

Strodl, Markus Andreas; Schausberger, Peter

2012-01-01

Background Social familiarity, which is based on the ability to recognise familiar conspecific individuals following prior association, may affect all major life activities of group-living animals such as foraging, reproduction and anti-predator behaviours. A scarcely experimentally tested explanation why social familiarity is beneficial for group-living animals is provided by limited attention theory. Limited attention theory postulates that focusing on a given task, such as inspection and assessment of unfamiliar group members, has cognitive and associated physiological and behavioural costs with respect to the attention paid to other tasks, such as anti-predator vigilance and response. Accordingly, we hypothesised that social familiarity enhances the anti-predator success of group-living predatory mites, Phytoseiulus persimilis, confronted with an intraguild predator, the predatory mite Amblyseius andersoni. Methodology/Principal Findings We videotaped and analysed the response of two P. persimilis larvae, held in familiar or unfamiliar pairs, to attacks by a gravid A. andersoni female, using the behavioural analyses software EthoVision Pro®. Familiar larvae were more frequently close together, reacted more quickly to predator attacks, survived more predator encounters and survived longer than unfamiliar larvae. Significance In line with the predictions of limited attention theory, we suggest that social familiarity improves anti-predator behaviours because it allows prey to shift attention to other tasks rather than group member assessment.

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.

Pragmatic multicentre, two arm, parallel group, randomised controlled trial. 20 study sites in 16 medium to large cities throughout France. 706 women aged 75-85, living in their own home, and with diminished balance and gait capacities, randomly allocated to the experimental intervention group (exercise programme, n=352) or the control group (no intervention, n=354). Weekly supervised group sessions of progressive balance training offered in community based premises for two years, supplemented by individually prescribed home exercises. A geriatrician blinded to group assignment classified falls into one of three categories (no consequence, moderate, severe) based on physical damage and medical care. The primary outcome was the rate of injurious falls (moderate and severe). The two groups were compared for rates of injurious falls with a "shared frailty" model. Other outcomes included the rates of all falls, physical functional capacities (balance and motor function test results), fear of falling (FES-I), physical activity level, and perceived health related quality of life (SF-36). Analysis was by intention to treat. There were 305 injurious falls in the intervention group and 397 in the control group (hazard ratio 0.81, 95% confidence interval 0.67 to 0.99). The difference in severe injuries (68 in intervention group v 87 in control group) was of the same order of magnitude (0.83, 0.60 to 1.16). At two years, women in the intervention group performed significantly better on all physical tests and had significantly better perception of their overall physical function than women in the control group. Among women who started the intervention (n=294), the median number of group sessions attended was 53 (interquartile range 16-71). Five injurious falls

Studies have demonstrated changes in activities of daily living after an exercise intervention in people with dementia (PWD) living in nursing homes (NH). However, some discrepancies are shown during follow-up. Our objective was to measure activities of daily living (ADL) performance during a 6-month observational follow-up after a 6-month exercise or social activity intervention in PWD living in NH. After cluster randomisation, 91 PWD living in NH performed a 6-month structured exercise intervention (n = 44) or a social activity intervention (n = 47). After the intervention, 85 PWD were assessed for post-intervention follow-up. Instrumental and basic activities of daily living (IADL, ADL) were measured at 6-month observational follow-up after the intervention using the Alzheimer's Disease Cooperative Study Activities of Daily Living Inventory for Severe Alzheimer's Disease (ADCS-ADL-sev) scale (scores ranging from 0 to 51, higher is better). Compared to participants in the social activity, those who participated to the exercise intervention had a significant decrease of their ADCS-ADL-sev score (between-group adjusted mean difference: 4.6 points, p = 0.001) with IADL having the most decrease (2.8 points, p = 0.004). Unexpectedly, exercisers declined sharply in the performance of ADLs and IADLs, whereas participants in the social intervention group maintained their levels. The potential mechanisms to explain these findings remain still to be elucidated.

From Social Exclusion to Supported Inclusion: Adults with Intellectual Disability Discuss Their Lived Experiences of a Structured Social Group.

People with intellectual disability often have few friends and experience social exclusion. Recognising this gap, supported social groups with the aim of inclusion and interdependence were created by a supported employment provider. Interviews were undertaken with 10 adults with intellectual disability exploring their lived experiences of a supported social group. Data were analysed using descriptive phenomenology. Two themes emerged (i) supported engagement fosters wellbeing, and (ii) developing social belonging and connectedness. Participants not only acknowledged the support that they needed to participate, but also that the social group had changed their lives in many ways. Adults with intellectual disability want to socialise, have friends and be part of their community. For this to be achieved, they recognise the need to seek some form of support. With appropriate and targeted support, adults with intellectual disability can move from social exclusion towards supported inclusion and experience richer lives. © 2016 The Authors Journal of Applied Research in Intellectual Disabilities Published by John Wiley & Sons Ltd.

Longer lives and extended retirement have created a 'young old age' stage of life. How people spend their "young old age" has become increasingly important. This research aims to investigate the different ageing experiences of Japanese and Malaysian women and the activities they engaged in their "young old age". In-depth interviews were conducted to collect data and an adapted grounded theory approach was used for data analysis. Findings reveal many common characteristics for both groups of research participants. The emerging themes show that Japanese and Malaysian Chinese have different life missions evident in their daily activities, one passing on culture and the other passing on family values and life experience. They also differ in their choice of living arrangement (independent versus dependent/interdependent), attitudes to life (fighting versus accepting) and activities in which to engage (aesthetic pursuits versus family oriented activities).

People living with HIV (PLWH) are living longer and are at greater risk for chronic comorbidities (e.g., cardiovascular disease, cancer) compared to those not living with HIV. Regular, sustained exercise can prevent and/or mitigate the severity of these comorbidities. Our purpose was to describe patterns of planned exercise implemented in the home setting (i.e., free-living exercise) in PLWH by gender and age. PLWH (n = 102) completed a sociodemographic survey and a 7-day exercise diary documenting daily exercise duration, frequency, and intensity. Women exercised an average of 2.4 (IQR: 0.5, 6.0) hours per week compared to men who exercised 3.5 (IQR: 0.5, 7.5) hours per week (p = 0.18). This relationship was particularly evident during middle adulthood for women versus for men (p = 0.05). PLWH exercised regularly but at less than recommended levels. This is among the first evidence describing free-living exercise patterns of PLWH. PMID:25249267

The increased number of adolescents and young adults with unknown or inaccurately given date of birth is a current issue in justice and legal medicine. The objective of this study was to determine the extent to which third molar calcification stages assessed on panoramic X-rays could be useful as additional criteria for forensic age estimation in living individuals, focusing on the legally important ages 17 and 18. In a retrospective multi-center study, the developmental stage of each individual's third molar was analyzed using Demirjian's scale in 2360 cases. Additionally, sex, age and ancestry were assessed. Individuals with the lowest calcification stage of all present molars in stage H were ≥18 years with a likelihood of ≥99.05% in the female (n=388), and ≥99.24% in the male (n=482) population. The lowest calcification stage of all present third molars proved to be useful as an additional reliable criterion for the determination of an age ≥18 years.

Social familiarity relaxes the constraints of limited attention and enhances reproduction of group-living predatory mites

PubMed Central

Strodl, Markus A; Schausberger, Peter

2013-01-01

In many group-living animals, within-group associations are determined by familiarity, i.e. familiar individuals, independent of genetic relatedness, preferentially associate with each other. The ultimate causes of this behaviour are poorly understood and rigorous documentation of its adaptive significance is scarce. Limited attention theory states that focusing on a given task has interrelated cognitive, behavioural and physiological costs with respect to the attention paid to other tasks. In multiple signal environments attention has thus to be shared among signals. Assuming that familiar neighbours require less attention than unfamiliar ones, associating with familiar individuals should increase the efficiency in other tasks and ultimately increase fitness. We tested this prediction in adult females of the group-living, plant-inhabiting predatory mite Phytoseiulus persimilis. We evaluated the influence of social familiarity on within-group association behaviour, activity, predation and reproduction. In mixed groups (familiar and unfamiliar), familiar predator females preferentially associated with each other. In pure groups (either familiar or unfamiliar), familiar predator females produced more eggs than unfamiliar females at similar predation rates. Higher egg production was correlated with lower activity levels, indicating decreased restlessness. In light of limited attention theory, we argue that the ability to discriminate between familiar and unfamiliar individuals and preferential association with familiar individuals confers a selective advantage because familiar social environments are cognitively and physiologically less taxing than unfamiliar social environments.

Recent demographic trends suggest that grandparents may play influential roles in the lives of their grandchildren. Despite this, the role of grandparents in the lives of youth remains an understudied topic. Using data from a nationally-representative group of youth aged 14–19 from the 1992 Wave Two National Survey of Families and Households (NSFH), this study seeks to better understand the role of grandparents in the lives of grandchildren by examining which factors predict the quality of the grandparent-grandchild relationship, and what the implications of this relationship are for youth. Key factors influencing the quality of the grandparent-grandchild relationship are distance, the parent’s relationship with both the grandparent and the child, and age of both the child and parent. Results do not support the hypothesis that grandparents influence the dimensions of youth well-being examined here. PMID:23049155

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.

500 years of mercury (Hg) mining in the town of Idrija has caused severe pollution in Idrija and its surroundings. Following the closure of the mine in 1995, the environment remains contaminated with Hg. Sources of elemental-, inorganic- and methyl Hg exposure were identified, potential environmental level of exposure to Hg was evaluated and actual internal exposure to Hg was assessed in selected susceptible population groups comprising school-age children and pregnant women living in Idrija and in control groups from rural and urban environments. The study of pregnant women (n=31) was conducted between 2003 and 2008, and the study of school-age children (n=176) in 2008. Potential interaction of Hg with selenium (Se) in plasma was assessed in both study populations, while in pregnant women antioxidative enzyme activity (glutathione peroxidase, superoxide dismutase and catalase) in erythrocytes of maternal and cord blood was also assessed. Actual exposure to Hg as indicated by levels of Hg in children's blood (geometric mean (GM) 0.92µg/L), mother's blood (GM 1.86µg/L), children's urine (GM 1.08µg/g crea.), mother's urine (GM 2.51µg/L), children's hair (GM 241ng/g) and mother's hair (GM 251ng/g) was higher in the two study groups from Idrija than in the control groups from rural areas, but was still at the level of a "normal" population and reflects mainly exposure to elemental Hg (Hg°) from dental amalgam and, to a certain extent atmospheric Hg°. Furthermore, the internal doses of Hg received during pregnancy did not decrease the bioavailability of Se. Based on observation in children, the increase in Se protein expression is suggested to be a consequence of moderately elevated exposure to Hg°. The observed changes in activity of antioxidative enzymes, as biomarkers of oxidative stress, appear to be mainly associated with pregnancy per se and not with an increased exposure to Hg. In view of the continuing increased potential for Hg exposure and the low

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.

Sexuality, aging, and dementia.

2012-07-01

Sexuality in later life and its relationship to dementia is a neglected topic: greater understanding of the area has the potential to contribute to the quality of life of people with dementia, their family members, and formal carers. We review current knowledge about sexuality, aging, and dementia. We undertook a review of the recent literature to examine of the following areas: what is known about sexuality and aging, and about attitudes to sexuality and aging; what is known about the relevance of sexuality and aging to people living with dementia and their care; and the management of sexual behaviors causing concern to others. Sexual activity decreases in frequency with increasing age but many older people remain sexually active; there is no age limit to sexual responsiveness; and sexuality is becoming more important to successive cohorts of older people, including people living with dementia and gay, lesbian, bisexual, and transgendered elderly people. Attitudes and beliefs toward sexuality and aging are strongly influenced by stereotypes and myths, not only among the general public but also among those working in health and social care. Professional bodies should include sexuality, aging, and dementia in their training curricula. More work is needed on the impact of environmental issues, particularly in group living situations, on older adults' sexuality, and on consent issues. Ethical decision-making frameworks can be useful in practice. Organizations should investigate how to support staff in avoiding a problem-orientated approach and focus on providing holistic person-centered care.

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.

This article discusses the ways in which artists have incorporated or failed to incorporate the aging process of their bodies into their art. Using Russian ballet dancer Mikhail Baryshnikov and the French painter Claude Monet as cases in point, we explore situations in which physical changes brought about by aging compromises artists' ability to engage with their artistic medium. Connecting Monet's oeuvre and Baryshnikov's dance performances to life writing accounts, we draw on John Paul Eakin's concept of "living autobiographically": In this vein, life writing research does not only have to take into account concepts of identity as they emerge from life writing narratives, but it also needs to explore the somatic, corporeal and material dimensions of these narratives.

Perceptions of competence: age moderates views of healthy aging and Alzheimer's disease.

Berry, Jane M; Williams, Helen L; Thomas, Kevin D; Blair, Jamie

2015-01-01

BACKGROUND/STUDY CONTEXT: Older adults have more complex and differentiated views of aging than do younger adults, but less is known about age-related perceptions of Alzheimer's disease. This study investigated age-related perceptions of competence of an older adult labeled as "in good health" (healthy) or "has Alzheimer's disease" (AD), using a person-perception paradigm. It was predicted that older adults would provide more differentiated assessments of the two targets than would younger adults. Younger (n=86; 18-36 years) and older (n=66; 61-95 years) adults rated activities of daily living (ADL), instrumental activities of daily living (IADL), and memory abilities of a female target aged 75 years, described as healthy or with AD. Data on anxiety about aging, knowledge of and experience with aging and AD, knowledge of memory aging, and positive and negative biases toward aging and AD were also collected. Older adults perceived the healthy target as more capable of cognitively effortful activities (e.g., managing finances) and as possessing better memory abilities than the AD target. As predicted, these differences were greater than differences between targets perceived by younger adults. The interaction effect remained significant after statistically controlling for relevant variables, including education and gender. Additionally, exploratory analyses revealed that older adults held less positively biased views of AD than younger adults, but negatively biased views were equivalent between age groups. The results demonstrate that mere labels of "healthy" and "Alzheimer's disease" produce significant and subtle age differences in perceived competencies of older adults, and that biases towards AD vary by age group and valence. Our findings extend the person-perception paradigm to an integrative analysis of aging and AD, are consistent with models of adult development, and complement current research and theory on stereotypes of aging.

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.

The objective of this study was to conduct focus groups with youth (18-29 years old) living with HIV (YLWH) to better understand preferences for mobile applications in general and to inform the design of a mobile health application aimed at improving retention and engagement in healthcare and adherence to antiretroviral therapy. We conducted four focus groups with YLWH to elicit the names and characteristics of applications that they commonly used, reasons they deleted applications, and the features of an ideal mobile health application. A diverse sample of youth (N = 17) with a mean age of 25 years, 88.2% male, and 29.4% African American participated in four focus groups. Positive attributes of applications included informative, simple, allowing for networking, timely updates, little overlap with other applications, unlimited access to entertainment, and with ongoing advancement. Participants identified several reasons for deleting applications, including engaging in excessive behaviors (e.g., spending money), for hook ups only, too many notifications or restrictions, occupied too much space on device, or required wireless connectivity or frequent updates. Participants suggested that a mobile health application that they would find useful should have the ability to connect to a community of other YLWH, readily access healthcare providers, track personal data and information (such as laboratory data), and obtain health news and education. Privacy was a key factor in a mobile health application for all participants. Researchers can use the information provided by focus group participants in creating mobile health applications for YLWH.

Cognitive rehabilitation has been developed to improve quality of life, activities of daily living and mood for people with cognitive impairment, but the voice of people with cognitive impairment has been underrepresented. This study aimed to understand the experience of people living with cognitive impairment, as well as their caregivers who took part in a cognitive rehabilitation intervention programme. Twelve individuals with cognitive impairment and 15 caregivers participated in individual qualitative interviews. The interview data were analysed in three steps: 1) familiarisation of the transcripts; 2) identification of themes; 3) re-interpretation, refinement and integration of themes with methodological auditors. Both participants living with cognitive impairment and caregivers valued the comfortable environment with friendly, caring and supportive group leaders who taught practical tips and strategies. The participants living with cognitive impairment enjoyed socialising with like others. Caregivers benefited from learning about memory problems and sharing their challenges with other caregivers. The participants living with cognitive impairment emphasised the benefits of relational and practical aspects, whereas the caregivers valued the informational and emotional support. In conclusion, both participants living with cognitive impairment and caregivers found the cognitive rehabilitation group useful.

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.

Nutrition plays a role in health promotion and well-being, but there is still a lack of knowledge about nutrition-related risk factors in aging cognitive impairment. The purpose of this project was to evaluate the link between nutritional status, cognitive performance and pro/antioxidant balance in healthy elderly subjects residing in a small metropolitan community. The subjects were 69 free-living urban healthy elderly people (41 females and 28 males aged 84+/-7 years, mean +/- standard deviation SD, range 70-89). In this group of elderly subjects an analysis of the diet over the 3 days before the study entry was performed. The nutrients intake for individuals were compared with the Italian Recommended Dietary Allowances (RDA). We also collected residents' background information, nutritional status (Mini Nutritional Assessment, MNA), and data on daily nursing routines in institutions, including nutritional care. Plasma malondialdehyde and erythrocyte glutathione peroxidase activity were evaluated in elderly people as compared to a group of healthy young people (control group) as indices of the oxidative balance. The mean vitamin and mineral intake for participants met the RDAs except for calcium and vitamin D. No difference was observed as regards plasma malondialdehyde between young and elderly subjects: 4.5 (3-6.2) mmol/L vs 4.45 (2.4-5.8) mmol/L respectively, median with range, whereas the latter exhibited higher erythrocyte glutathione peroxidase activity: 16.0 (9.3-48) U/g hemoglobin (Hb) vs 15 (10-35) U/g Hb, respectively, median with range (P<0.05). A significant negative correlation (P<0.05, r=0.24) between dietary intake of vitamin D and malondialdeyde and between dietary intake of vitamin D and poor performance on cognitive tests (P<0.01, r=0.35) was observed. In line with previous findings, our results highlighted the potential impact of nutritional factors on cognitive performance in older adults.

This exploratory study used focus groups to examine attitudes and beliefs of HIV-infected African American women of child-bearing age about pregnancy and antiretroviral therapy. A convenience sample of thirty-three African American women of child-bearing age participated in five focus groups. Attitudes and beliefs about pregnancy decisions and the use of antiretroviral therapy during pregnancy were examined. Many of the women in this study living with HIV remained committed to having children and expressed confusion about their chances of transmitting the virus to their children. Health care providers must be aware of these concerns and convey clear and accurate information through the most readily accepted channels. Participants suggested that messages about these issues be conveyed by other women living with HIV who have faced these same decisions.

To identify major dietary patterns and their association with socio-economic status (SES) and food insecurity in two major ethnic groups living in Urmia, north-west Iran. A cross-sectional study. All four geographical zones of Urmia city. Participants (n 723; 427 women and 296 men), aged 20-64 years, from two ethnic groups (445 Azeri Turks and 278 Kurds). Three major dietary patterns were extracted: 'Traditional High SES' (THS), 'Traditional Low SES' (TLS) and 'Transitional'. After adjusting for confounders, the THS pattern was positively associated with education level and negatively associated with moderate or severe food insecurity in Azeri Turks; whereas, among Kurds, it was more common in women and positively associated with age. The TLS pattern was more common among men and negatively associated with educational level and all levels of food insecurity in Azeris; while, among Kurds, it was more common among men, positively associated with being married and negatively associated with household income/capita. The 'Transitional' pattern was positively associated with being employed and negatively associated with age and all levels of food insecurity in Azeris; while, among Kurds, it was more common among men and negatively associated with age, being married and physical activity level. Findings suggest that household SES and food insecurity are associated with detrimental dietary patterns and that this effect may be stronger than cultural and ethnic background. These patterns differ by age and gender. Therefore, such characteristics should be considered in planning and formulating diet-related policies and programmes.

To date, only limited cases of Diego blood group disparity in liver transplantation have been reported, and no cases with a long-term clinical course have been documented. Herein, we report a case of Diego blood group disparity in liver transplantation with details of long-term follow-up. The recipient was a 47-year-old woman with primary biliary cirrhosis; her 18-year-old daughter was the donor. Both recipient and donor were of blood type O according to the ABO blood group system. Preoperative serological tests showed the presence of antibodies against the Di(a) antigen only in the recipient, and not in the donor. Thus, the Diego phenotype was Di(a+) in the donor and Di(a-) in the recipient. Living-related liver transplantation was performed in July 2009. Immediate graft function was obtained, and no signs of humoral or cellular rejection were observed during the postoperative period. Further, anti-Di(a) antibodies were not detected throughout the postoperative course. The patient is alive and shows no signs of humoral rejection 34 months after liver transplantation. Liver transplantation has been performed successfully in cases of Diego blood group disparity. Copyright © 2013 Elsevier Inc. All rights reserved.

The purpose of this study was to compare the effects of 16-week group exercise program on the physical function (ie, strength, flexibility, and balance) and mental health (ie, self-esteem and depression) of older elderlyl women (>or=75 years old) compared with younger elderly women (<75 years old). Exercise is crucial in maintaining older women's health and well-being. However, because most elders have at least one chronic disease, their physical function declines, so their dependence on others for instrumental daily living activities often increases. Older women typically have multiple barriers to participation in physical activities including higher disability rates. Of the total of 40 older women (older than 65 years) enrolled, 21 were older elders and 16 were younger elders. Lower body strength (using 30-second chair test), flexibility (sit-and-reach test), and static balance (ability to balance on one leg with open and closed eyes) were assessed. Self-esteem (using Rosenberg's Self-esteem Questionnaire) and depressive symptoms (using Yesavage's Geriatric Depression Scale) were assessed. Two-way analysis of variance was used to examine the differences between the 2 age groups. The intervention program was effective in improving body strength, flexibility, static balance, and self-esteem, regardless of age. Furthermore, older elders receiving the intervention program demonstrated greater improvement in self-esteem than younger elders did, although there were intervention effects in both age groups. Elderly women can realize benefits from a group exercise program that can improve their functional ability and self-esteem, both important to cardiovascular health.

This study evaluated the associations between oral and general health behaviours, self-reported health and quality of life of adults aged 75 years or older living independently in South Australia. A cross sectional study based on a self-report mailed questionnaire was conducted in 590 independently living adults aged 75 years or older. Self-ratings of oral health and general health were assessed using single-item global ratings. Quality of life was measured using the Oral Health Impact Profile and the EuroQol instrument for health utility. The overall response rate was 78%. The current analyses were restricted to 354 dentate older adults. Increasing age and being female were negatively associated with EuroQol scores. Good self-rated oral and general health were more prevalent in participants with higher social status who also had lower oral health impact and higher EuroQol scores. Good self-rated oral and general health were less prevalent while oral health impact was greater in participants who ate few fruits, vegetables or dairy products. Self-rated health and quality of life were poor in older adults with inadequate fruit/vegetables/dairy intake and lower social status. These findings suggest that nutrition and socioeconomic factors may be important to the oral and general health of adults aged 75 years or older. © 2018 Australian Dental Association.

Visceral leishmaniasis (VL) caused by the protozoan parasite Leishmania donovani causes severe disease. Age appears to be critical in determining the clinical outcome of VL and at present there is no effective vaccine available against VL for any age group. Previously, we showed that genetically modified live attenuated L. donovani parasites (LdCen-/-) induced a strong protective innate and adaptive immune response in young mice. In this study we analyzed LdCen-/- parasite mediated modulation of innate and adaptive immune response in aged mice (18 months) and compared to young (2 months) mice. Analysis of innate immune response in bone marrow derived dendritic cells (BMDCs) from both young and aged mice upon infection with LdCen-/- parasites, showed significant enhancement of innate effector responses, which consequently augmented CD4+ Th1 cell effector function compared to LdWT infected BMDCs in vitro. Similarly, parasitized splenic dendritic cells from LdCen-/- infected young and aged mice also revealed induction of proinflammatory cytokines (IL-12, IL-6, IFN-γ and TNF) and subsequent down regulation of anti-inflammatory cytokine (IL-10) genes compared to LdWT infected mice. We also evaluated in vivo protection of the LdCen-/- immunized young and aged mice against virulent L. donovani challenge. Immunization with LdCen-/- induced higher IgG2a antibodies, lymphoproliferative response, pro- and anti-inflammatory cytokine responses and stimulated splenocytes for heightened leishmanicidal activity associated with nitric oxide production in young and aged mice. Furthermore, upon virulent L. donovani challenge, LdCen-/- immunized mice from both age groups displayed multifunctional Th1-type CD4 and cytotoxic CD8 T cells correlating to a significantly reduced parasite burden in the spleen and liver compared to naïve mice. It is interesting to note that even though there was no difference in the LdCen-/- induced innate response in dendritic cells between aged and young

The purpose of this study was to investigate how quality of life outcome after bilateral subthalamic nucleus (STN) deep brain stimulation (DBS) in Parkinson's disease (PD) depends on age. In this prospective, open-label, multicenter study including 120 PD patients undergoing bilateral STN-DBS, we investigated the PDQuestionnaire-8 (PDQ-8), Unified PD Rating Scale-III, Scales for Outcomes in PD-motor examination, complications, activities of daily living, and levodopa equivalent daily dose preoperatively and at 5 months follow-up. Significant changes at follow-up were analyzed with Wilcoxon signed-rank test and Bonferroni correction for multiple comparisons. To explore the influence of age post hoc, the patients were classified into 3 age groups (≤59, 60-69, ≥70 years). Intragroup changes were analyzed with Wilcoxon signed-rank and intergroup differences with Kruskal-Wallis tests. The strength of clinical responses was evaluated using effect size. The PDQuestionnaire-8, Scales for Outcomes in PD-motor complications, activities of daily living, and levodopa equivalent daily dose significantly improved in the overall cohort and all age groups with no significant intergroup differences. However, PDQuestionnaire-8 effect sizes for age groups ≤59, 60 to 69, and ≥70 years, respectively, were strong, moderate, and small. Furthermore, PDQuestionnaire-8 domain analyses revealed that all domains except cognition and emotional well-being significantly improved in patients aged ≤59 years, whereas only communication, activities of daily living, and stigma improved in patients aged 60-69 years, and activities of daily living and stigma in patients aged ≥70 years. Although quality of life, motor complications, and activities of daily living significantly improved in all age groups after bilateral STN-DBS, the beneficial effect on overall quality of life was more pronounced and affected a wider range of quality of life domains in younger patients. © 2017 International

[Cytokine dysregulation in children with chronic catarrhal gingivitis living in polluted areas with fluoride and iodine deficiency].

PubMed

Bezvushko, E V; Malko, N V

The aim of the research was to study the state of oral liquid immunity in children with chronic catarrhal gingivitis living in unfavorable environmental conditions. The study included 190 children with chronic catarrhal gingivitis (CCG): 110 children aged 7, 12 and 15 years and residing in ecologically unfavorable areas of Lviv region and 80 children living in 'conditionally clean' region which constituted comparison group. Children with CCG from polluted areas had increased content of pro-inflammatory cytokines and reduction of anti-inflammatory cytokines compared to controls. The level of pro-inflammatory cytokines was age-depended in both groups but in children from ecologically unfavorable region this tendency was more pronounced. Thus, changes of indicators of interleukin spectrum in children with CCG depend not only on age and degree of severity of periodontium pathology but also on ecological living conditions.

Lack of financial resources has become one of the main issues in fulfilling social and physical needs in urban development. The declining levels of public resources make the collaboration between public and private investors necessary. When facing the challenges of ageing population, shared investment may contribute to the appropriate development of sheltered housing to meet the goals of spatial planning as well as certain standards at the level of urban design. By ensuring appropriate living conditions for all generations such urban PPP projects may contribute to the fulfilment of the public interest. The paper presents practice of PPP implementation in Ljubljana, Slovenia, where local authority with the collaboration of private partners ensured more than 400 sheltered apartments in the last years. Examples show the extension of the idea from the 70s onwards in finding new models of housing for the aging population. The development of new models can be a good example of strengthening the cooperation between public and private partners in the field of urban development practice.

Investigation of human CNS disease and drug effects has been hampered by the lack of a system that enables single-cell analysis of live adult patient brain cells. We developed a culturing system, based on a papain-aided procedure, for resected adult human brain tissue removed during neurosurgery. We performed single-cell transcriptomics on over 300 cells, permitting identification of oligodendrocytes, microglia, neurons, endothelial cells, and astrocytes after 3 weeks in culture. Using deep sequencing, we detected over 12,000 expressed genes, including hundreds of cell-type-enriched mRNAs, lncRNAs and pri-miRNAs. We describe cell-type- and patient-specific transcriptional hierarchies. Single-cell transcriptomics on cultured live adult patient derived cells is a prime example of the promise of personalized precision medicine. Because these cells derive from subjects ranging in age into their sixties, this system permits human aging studies previously possible only in rodent systems. Copyright © 2017 The Author(s).

2013-05-01

In order to maintain one's state of health whilst growing older, the ability to walk is essential. The aim of this study was to illuminate the meanings of the lived experience of living in an ageing body and using a walker in daily life. Narrative interviews were performed with seven older persons aged 79-95 years. The transcribed text was analysed using a phenomenological hermeneutic method. The key finding of the study was that the lived experience of living in an ageing body and using a walker in daily life was interpreted as 'walking on the edge' based on the themes 'Being vulnerable and dependent' and 'Being confident and independent'. The results highlight the importance of reflecting on this phenomenon as a health care professional while meeting the care needs of older persons who use walkers. Nurses need to consider the walker as a personal and valued possession of the individual and handle the walker in agreement with the older person, placing the walker close at hand with the brakes locked to give secure support. © 2012 Blackwell Publishing Ltd.

Annual age-grouping and athlete development: a meta-analytical review of relative age effects in sport.

PubMed

Cobley, Stephen; Baker, Joseph; Wattie, Nick; McKenna, Jim

2009-01-01

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.

The study aimed: (1) to compare levels of well-being and distress in older adults living in nursing homes with those living in community; and (2) to test the feasibility of a positive narrative intervention for improving well-being versus a control art-and-craft intervention in a nursing home setting. Sixty older adults participated in the study (M = 77.37; SD = 5.00), Male = 20 (33.3%). In Study 1, 30 adults living in nursing homes were compared with 30 community-dwellers using the following measures: Satisfaction with Life Scale, Psychological Well-being Scale, Social Well-being Scale, Geriatric Depression Scale, and sleep quality. In Study 2, the same 30 adults living in nursing homes were allocated to a positive narrative intervention group (N = 20) or to a control group (N = 10) and assessed at post-intervention. In Study 1, older adults in nursing homes presented more depression and impairments in well-being, compared to community-dwellers. In Study 2, at post-treatment, individuals assigned to the narrative intervention reported significantly increased well-being and sleep quality. Although preliminary, results showed that older adults living in nursing homes are more vulnerable than community-dwellers. These patients experienced improvement when given a short group positive narrative intervention applicable in nursing homes. A brief group intervention based on fairy tales yielded improvements in well-being and sleep quality in nursing home residents, who enjoyed and appreciated its content. These promising results need to be confirmed by future randomized controlled trials.

As part of the 12-month follow-up of the longitudinal cohort study, Life and Living in Advanced Age: A Cohort Study in New Zealand, dietary intake was assessed in 216 Māori and 362 non-Māori octogenarians using repeat 24-h multiple pass recalls. Energy and macronutrient intakes were calculated, and food items reported were allocated to food groups used in the New Zealand Adult Nutrition Survey (NZANS). Intakes were compared with the nutrient reference values (NRV) for Australia and New Zealand. The median BMI was higher for Māori (28·3 kg/m2) than for non-Māori (26·2 kg/m2) P=0·007. For Māori, median energy intake was 7·44 MJ/d for men and 6·06 MJ/d for women with 16·3 % energy derived from protein, 43·3 % from carbohydrate and 38·5 % from fat. Median energy intake was 7·91 and 6·26 MJ/d for non-Māori men and women, respectively, with 15·4 % of energy derived from protein, 45 % from carbohydrate and 36·7 % from fat. For both ethnic groups, bread was the top contributor to energy and carbohydrate intakes. Protein came from beef and veal, fish and seafood, bread, milk and poultry with the order differing by ethnic groups and sex. Fat came mainly from butter and margarine. Energy-adjusted protein was higher for Māori than non-Māori (P=0·049). For both ethnic groups, the median energy levels were similar, percent carbohydrate tended to be lower and percent fat higher compared with adults aged >70 years in NZANS. These unique cross-sectional data address an important gap in our understanding of dietary intake in this growing section of our population and highlight lack of age-appropriate NRV.

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.

A panel multinomial logit analysis of elderly living arrangements: evidence from Aging In Manitoba longitudinal data, Canada.

Sarma, Sisira; Simpson, Wayne

2007-12-01

Utilizing a unique longitudinal survey linked with home care use data, this paper analyzes the determinants of elderly living arrangements in Manitoba, Canada using a random effects multinomial logit model that accounts for unobserved individual heterogeneity. Because current home ownership is potentially endogenous in a living arrangements choice model, we use prior home ownership as an instrument. We also use prior home care use as an instrument for home care and use a random coefficient framework to account for unobserved health status. After controlling for relevant socio-demographic factors and accounting for unobserved individual heterogeneity, we find that home care and home ownership reduce the probability of living in a nursing home. Consistent with previous studies, we find that age is a strong predictor of nursing home entry. We also find that married people, those who have lived longer in the same community, and those who are healthy are more likely to live independently and less likely to be institutionalized or to cohabit with individuals other than their spouse.

Wound age determination in living subjects is important in routine diagnostics in forensic medicine. Macroscopical description of a wound to determine wound age however is inadequate. The aim of this study was to assess whether it would be feasible to determine wound age via analysis of morphological characteristics and extracellular matrix proteins in skin biopsies of living subjects referred to a forensic outpatient clinic. Skin biopsies (n=101), representing the border area of the wound, were taken from skin injuries of known wound age (range: 4.5h-25 days) in living subjects. All biopsies were analyzed for 3 morphological features (ulceration, parakeratosis and hemorrhage) and 3 extracellular matrix markers (collagen III, collagen IV and α-SMA). For quantification, biopsies were subdivided in 4 different timeframes: 0.2-2 days, 2-4 days, 4-10 days and 10-25 days old wounds. Subsequently, a probability scoring system was developed. For hemorrhage, collagen III, collagen IV and α-SMA expression no relation with wound age was found. Ulceration was only found in wounds of 0.2-2, 2-4 and 4-10 days old, implying that the probability that a wound was more than 10 days old in case of ulceration is equal to 0%. Also parakeratosis was almost exclusively found in wounds of 0.2-2, 2-4 and 4-10 days old, except for one case with a wound age of 15 days old. The probability scoring system of all analyzed markers, as depicted above, however can be used to calculate individual wound age probabilities in biopsies of skin wounds of living subjects. We have developed a probability scoring system, analysing morphological characteristics and extracellular matrix proteins in superficial skin biopsies of wounds in living subjects that can be applied in forensic medicine for wound age determination.

A descriptive exploratory study was conducted in the municipality of Maringá, Paraná, Brazil to identify the profile of a group of elderly people participating in a geriatric care project in regard to socio-demographic factors and family interaction, as well as to describe how physical activity influenced their lives. The data were collected in September 2006 through a semistructured interview with 35 members of a group practicing physical activities. The results revealed the individuals were mainly females, 70 years old or younger, married retired and living with their families. They described as positive their family life, which was characterized by going out together, making decisions and experiencing few conflicts. Most of them said that the fitness activities had improved their physical and emotional health. It was concluded that besides the physical improvement, the activities created opportunities for social contacts and therefore, contributed to emotional wellbeing.

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.

Objectives. We investigated the contributions of gender, caste, and standard of living to inequalities in mortality across the life course in India. Methods. We conducted a multilevel cross-sectional analysis of individual mortality, using the 1998–1999 Indian National Family Health Survey data for 529321 individuals from 26 states. Results. Substantial mortality differentials were observed between the lowest and highest standard-of-living quintiles across all age groups, ranging from an odds ratio (OR) of 4.61 (95% confidence interval [CI]=2.98, 7.13) in the age group 2 to 5 years to an OR of 1.97 (95% CI=1.68, 2.32) in the age group 45 to 64 years. Excess mortality for girls was evident only for the age group 2 to 5 years (OR=1.33, 95% CI=1.13, 1.58). Substantial caste differentials were observed at the beginning and end stages of life. Area variation in mortality is partially a result of the compositional effects of household standard of living and caste. Conclusions. The mortality burden, across the life course in India, falls disproportionately on economically disadvantaged and lower-caste groups. Residual state-level variation in mortality suggests an underlying ecology to the mortality divide in India. PMID:16571702

Gene expression profiling of long-lived dwarf mice: longevity-associated genes and relationships with diet, gender and aging

PubMed Central

Swindell, William R

2007-01-01

Background Long-lived strains of dwarf mice carry mutations that suppress growth hormone (GH) and insulin-like growth factor I (IGF-I) signaling. The downstream effects of these endocrine abnormalities, however, are not well understood and it is unclear how these processes interact with aging mechanisms. This study presents a comparative analysis of microarray experiments that have measured hepatic gene expression levels in long-lived strains carrying one of four mutations (Prop1df/df, Pit1dw/dw, Ghrhrlit/lit, GHR-KO) and describes how the effects of these mutations relate to one another at the transcriptional level. Points of overlap with the effects of calorie restriction (CR), CR mimetic compounds, low fat diets, gender dimorphism and aging were also examined. Results All dwarf mutations had larger and more consistent effects on IGF-I expression than dietary treatments. In comparison to dwarf mutations, however, the transcriptional effects of CR (and some CR mimetics) overlapped more strongly with those of aging. Surprisingly, the Ghrhrlit/lit mutation had much larger effects on gene expression than the GHR-KO mutation, even though both mutations affect the same endocrine pathway. Several genes potentially regulated or co-regulated with the IGF-I transcript in liver tissue were identified, including a DNA repair gene (Snm1) that is upregulated in proportion to IGF-I inhibition. A total of 13 genes exhibiting parallel differential expression patterns among all four strains of long-lived dwarf mice were identified, in addition to 30 genes with matching differential expression patterns in multiple long-lived dwarf strains and under CR. Conclusion Comparative analysis of microarray datasets can identify patterns and consistencies not discernable from any one dataset individually. This study implements new analytical approaches to provide a detailed comparison among the effects of life-extending mutations, dietary treatments, gender and aging. This comparison

2002-08-01

This research found that older individuals with more positive self-perceptions of aging, measured up to 23 years earlier, lived 7.5 years longer than those with less positive self-perceptions of aging. This advantage remained after age, gender, socioeconomic status, loneliness, and functional health were included as covariates. It was also found that this effect is partially mediated by will to live. The sample consisted of 660 individuals aged 50 and older who participated in a community-based survey, the Ohio Longitudinal Study of Aging and Retirement (OLSAR). By matching the OLSAR to mortality data recently obtained from the National Death Index, the authors were able to conduct survival analyses. The findings suggest that the self-perceptions of stigmatized groups can influence longevity.

2014-03-01

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.

Gupta, Pradeep; Malviya, Manohar

2017-01-01

Introduction Electric contact burn is characterised by multiple wounds produced by entrance and exit of the current. Hand is most commonly involved in the same and children are particularly susceptible to such accidents. Aim To document effectiveness and challenges associated with the use of groin flap as an initial definitive treatment of electric contact burn in paediatric age group. Materials and Methods From January 2015 to December 2016, 25 children up to 12 years of age, who were admitted at SMS Medical College, Jaipur, Rajasthan, India, after electric burn injury with hand defect and who were treated by pedicled groin flap at the Department of Plastic and Reconstructive Surgery, were included in the study. Details related to gender, age, type of voltage injury, sites of injury and postoperative complications were recorded. The groin flap was used in these children for coverage of hand and finger defect with exposed bone and tendon. Results Normal functional results were seen in all children treated with pedicled groin flap and all were able to perform activities of daily living. All the children had satisfactory aesthetic result. Conclusion Although, groin flap was an uncomfortable procedure due to limb position that was particularly difficult for children, it was found to be a useful method to salvage hand and it resulted in favourable functional and aesthetic outcome in each case.

The data were gathered from a survey, using face-to-face interviews. The Mini Nutritional Assessment (MNA) was used in evaluating each individual's nutrition. The rate of malnutrition in the study population was 5% while the malnutrition risk was 67%. The rate of malnutrition in the individuals living alone was found to be higher than that of those living with their families. The rates of malnutrition in individuals living alone and with their families were, respectively, 7% and 4%, and the rates of malnutrition risk in individuals living alone and with their families were, respectively, 73% and 66% (p<0.05). In both groups, there were significant relationships between individuals' ages, BMI values, mid-upper arm circumference (MUAC), and calf circumference measurements and their MNA scores. While there was a negative and significant relationship between age and MNA scores, the relationships between other parameters and MNA scores were positive and significant (p<0.01). In this study, it was revealed that the nutrition of elderly individuals living alone differs from the nutrition of elderly individuals living with their families. Malnutrition rates were higher in individuals living alone. Raising the awareness of elderly people and their families regarding the need to improve and maintain nutrition would be beneficial.

Summary Aging is a complex process that affects multiple organs. Modeling aging and age-related diseases in the lab is challenging because classical vertebrate models have relatively long lifespans. Here we develop the first platform for rapid exploration of age-dependent traits and diseases in vertebrates, using the naturally short-lived African turquoise killifish. We provide an integrative genomic and genome-editing toolkit in this organism using our de novo-assembled genome and the CRISPR/Cas9 technology. We mutate many genes encompassing the hallmarks of aging, and for a subset, we produce stable lines within 2–3 months. As a proof-of-principle, we show that fish deficient for the protein subunit of telomerase exhibit the fastest onset of telomere-related pathologies among vertebrates. We further demonstrate the feasibility of creating specific genetic variants. This genome-to-phenotype platform represents a unique resource for studying vertebrate aging and disease in a high throughput manner and for investigating candidates arising from human genome-wide studies.

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.

Objectives. We compared the social participation of older adults living in metropolitan, urban, and rural areas, and identified associated environmental factors. Methods. From 2004 to 2006, we conducted a cross-sectional study using an age-, gender-, and area-stratified random sample of 1198 adults (aged 67–82 years). We collected data via interviewer-administered questionnaires and derived from Canadian censuses. Results. Social participation did not differ across living areas (P = .09), but after controlling for potential confounding variables, we identified associated area-specific environmental variables. In metropolitan areas, higher social participation was associated with greater proximity to neighborhood resources, having a driver’s license, transit use, and better quality social network (R2 = 0.18). In urban areas, higher social participation was associated with greater proximity to neighborhood resources and having a driver’s license (R2 = 0.11). Finally, in rural areas, higher social participation was associated with greater accessibility to key resources, having a driver’s license, children living in the neighborhood, and more years lived in the current dwelling (R2 = 0.18). Conclusions. To enhance social participation of older adults, public health interventions need to address different environmental factors according to living areas. PMID:25689194

The unmet demand for kidney transplantation has generated intense controversy about introducing incentives for living kidney donors to increase donation rates. Such debates may affect public perception and acceptance of living kidney donation. This study aims to describe the range and depth of public opinion on financial reimbursement, compensation, and incentives for living kidney donors. Twelve focus groups were conducted with 113 participants recruited from the general public in three Australian states in February 2013. Thematic analysis was used to analyze the transcripts. Five themes were identified: creating ethical impasses (commodification of the body, quandary of kidney valuation, pushing moral boundaries), corrupting motivations (exposing the vulnerable, inevitable abuse, supplanting altruism), determining justifiable risk (compromising kidney quality, undue harm, accepting a confined risk, trusting protective mechanisms, right to autonomy), driving access (urgency of organ shortage, minimizing disadvantage, guaranteeing cost-efficiency, providing impetus, counteracting black markets), and honoring donor deservingness (fairness and reason, reassurance and rewards, merited recompense). Reimbursement and justifiable recompense are considered by the Australian public as a legitimate way of supporting donors and reducing disadvantage. Financial payment beyond reimbursement is regarded as morally reprehensible, with the potential for exploitative commercialism. Some contend that regulated compensation could be a defensible strategy to increased donation rates provided that mechanisms are in place to protect donors. The perceived threat to community values of human dignity, goodwill, and fairness suggests that there could be strong public resistance to any form of financial inducements for living kidney donors. Policy priorities addressing the removal of disincentives may be more acceptable to the public. Copyright © 2015 by the American Society of Nephrology.

2017-07-01

The aim of this paper is to investigate ageing changes in craniofacial region in both sexes and evaluate whether these shape changes are substantial to achieve age discrimination of samples used in anthropological analyses. The study sample consisted of 157 crania of known sex and age (81 males and 76 females) belonging to individuals who lived in Greece during the twentieth century. The sample was divided in three age groups: young adults (YA, 18-39 years old), middle adults (MA, 40-59 years old) and old adults (OA, >60 years old). The three-dimensional coordinates of 31 ecto-cranial landmarks were digitized using a Microscribe 3DX contact digitizer, and landmark configurations were analyzed using the generalized least-squares Procrustes method. The results indicate that both males and females show significant difference among the age groups; however, shape differences can not be used for age group discrimination due to a large range on the accuracy of age group classification. The morphometric changes related to age were different between sexes.

The great gerbil, Rhombomys opinus, is a highly social rodent that usually lives in family groups consisting of related females, their offspring, and an adult male. The gerbils emit alarm vocalizations in the presence of diverse predators with different hunting tactics. Alarm calls were recorded in response to three predators, a monitor lizard, hunting dog, and human, to determine whether the most common call type, the rhythmic call, is functionally referential with regard to type of predator. Results show variation in the alarm calls of both adults and subadults with the type of predator. Discriminant function analysis classified an average of 70% of calls to predator type. Call variation, however, was not limited to the predator context, because signal structure also differed by sex, age, individual callers, and family groups. These variations illustrate the flexibility of the rhythmic alarm call of the great gerbil and how it might have multiple functions and communicate in multiple contexts. Three alarm calls, variation in the rhythmic call, and vibrational signals generated from foot-drumming provide the gerbils with a varied and multi-channel acoustic repertoire.

Older adults' experiences of living with cleft lip and palate: a qualitative study exploring aging and appearance.

Objective : To explore older adults' experiences of living with cleft lip and/or palate (CL/P), focusing on aging and appearance. Design : An exploratory-descriptive qualitative study. Participants : Individual semi-structured interviews (five via telephone, one face-to-face) conducted with six adults between the ages of 57 and 82 years. Results : Interview transcripts were analyzed using interpretative phenomenological analysis, which resulted in five themes: cleft across the life span, keeping up appearances, being one of a kind, resilience and protection, and cleft in an ever-changing society. A CL/P had an ongoing impact on participants' lives, although its relevance shifted over time and some aspects of life (e.g., romantic relationships, decisions about having children of their own) were particularly affected. Participants seemed at ease living with CL/P as an older adult and considered it an important aspect of their identity, yet they still described feeling isolated at times and had little contact with other people with a cleft. They felt that health care could be more considerate to the needs of older people with a cleft, particularly around dentistry and information provision. Participants thought societal attitudes toward visible differences had changed over the years, but not necessarily for the better. A paradox was evident between reports of being noticed by others because of their cleft and simultaneously feeling invisible or ignored because of their age. Conclusions : These findings have implications for provision of care for older adults with a CL/P and for younger people with a CL/P who will be the older generation of the future.

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

Our study population consisted of 402 Living Related Donors (LRD)--of which 344 pairs shared 1 haplotype (Group A) and of 209 Living Unrelated Donors (LURD) (Group B): 175 between spouse pairs (Group C)--132 from wife to husband (Group C1) and 43 from husband to wife (Group C2) as well as 32 between relatives in law or emotionally related patients and 2 between members of clergy (Group D). 199 pairs showed 3-6 HLA A B Dr mismatches (MM) with the donor and in 10 cases 0-2 MM. Donor and recipient mean age was 49 +/- 13.4 and 29 +/- 10.3 in Group A and respectively 46 +/- 11.2 and 48 +/- 9.6 in Group B. The post-transplant immunosuppression therapy was based on Cyclosporin A (CsA). Chi2 test was used to assess statistical significance. Donor mortality was 0%; perioperative morbidity was 15.2%. Graft function immediately started after surgery. The actuarial 1 yr, 5 yrs, 10 yrs and 15 yrs graft survival was in Group A: 94%, 86%, 84%, 75% vs. Group B: 89%, 78%, 71%, 70% (NS), Group C1: 90%, 75%, 67%, 69% vs. Group C2: 81%, 74%, 72%, 62% (NS) and Group C: 88%, 78%, 66%, 60% vs. Group D: 91%, 80%, 71%, 61% (NS). There was no statistically significant difference between LURD and LRD as far as graft survival. In conclusion, we certainly agree with the guidelines issued by the International Congress on Ethics in Organ Transplantation (Munich, December 10-13,2002): kidney transplantation from living donors is a safe and effective procedure and should not be discouraged.

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 determine the association between neighborhood domestic violence and small-for-gestational-age (SGA) birth and to examine if there is a differential impact of neighborhood domestic violence on SGA births by race in a high crime community. This analysis includes all birth records issued in New Orleans, Louisiana from 2011 to 2012 geocoded by census tract (N=177 census tracts, N=8322 women). Hierarchical modeling and ecologic spatial analysis were used to examine the area-effect of neighborhood domestic violence on SGA births, independent of individual-level predictors and accounting for the propensity to live in high domestic violence neighborhoods. Tests for spatial autocorrelation reveled area-level clustering and overlap of SGA and domestic violent rates. Pregnant women living in high domestic violence areas were more likely to give birth to an SGA infant compared to women in low-domestic violence areas (OR=1.04, 95%CI: 1.01, 1.08), net of the effects of individual-level factors and propensity scores. Neighborhood-level attributes including rates of domestic violence may increase women's risk for SGA birth, highlighting a policy-relevant and potentially amenable exposure.

Group B Streptococcus causes a variety of morbid and sometimes fatal conditions affecting individuals of all age groups. There are nine known serotypes of this Gram-positive coccus but few estimates of the incidence and duration of its colonization and none by serotype in the literature. In 2001, the authors conducted a prospective cohort study among 257 men and women living in a single dormitory in Ann Arbor, Michigan. The 3-week incidence with any serotype was 11.3% (+/-3.9%) among women and 8.8% (+/-3.0%) among men; 3-week incidence rates were highest for serotype V (4.7% for women and 3.5% for men) and type Ia (2.3% for women and 2.4% for men), with no significant differences by gender. The estimated average duration of any group B Streptococcus colonization was longer for women (13.7 weeks) than men (8.5 weeks); serotype Ia was carried an average of 6.5 weeks longer in women, and serotype III was carried 4.9 weeks longer. Colonization with more than one serotype occurred significantly less than would be expected by chance (p < 0.001). Based on the overall incidence, transmission occurred between roommate pairs at the rate expected. Group B Streptococcus colonization is frequent and dynamic, but it is not transmitted by casual contact.

To identify HIV-socioeconomic predictors as well as the most-at-risk groups of women in Malawi. A cross-sectional survey. Malawi The study used a sample of 6395 women aged 15-49 years from the 2010 Malawi Health and Demographic Surveys. Individual HIV status: positive or not. Findings from the Pearson χ(2) and χ(2) Automatic Interaction Detector analyses revealed that marital status is the most significant predictor of HIV. Women who are no longer in union and living in the highest wealth quintiles households constitute the most-at-risk group, whereas the less-at-risk group includes young women (15-24) never married or in union and living in rural areas. In the light of these findings, this study recommends: (1) that the design and implementation of targeted interventions should consider the magnitude of HIV prevalence and demographic size of most-at-risk groups. Preventive interventions should prioritise couples and never married people aged 25-49 years and living in rural areas because this group accounts for 49% of the study population and 40% of women living with HIV in Malawi; (2) with reference to treatment and care, higher priority must be given to promoting HIV test, monitoring and evaluation of equity in access to treatment among women in union disruption and never married or women in union aged 30-49 years and living in urban areas; (3) community health workers, households-based campaign, reproductive-health services and reproductive-health courses at school could be used as canons to achieve universal prevention strategy, testing, counselling and treatment.

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.

We examined the effect of sociodemographic factors, cancer, and psychiatric disorders on suicide by gender and age-specific patterns in South Korea. The study is a case-control study. Claim data was obtained from the national health insurance database and national death registration database. The number of people who committed suicide was 11,523, which was matched with a control group consisting of ten times as many people at 115,230 selected from the national health insurance and medical aids beneficiaries. The medical utilization of the case group was one year before death and that of the control group was from July 1,2003 to June 30, 2004. Four variables-address, economic status, presence of a psychiatric disease, and cancer-were used in multiple logistic regression analyses. Living in cities or in rural areas showed a greater risk for suicide than living in a metropolitan city. Low economic status, the presence of a psychiatric disorder, and cancer were also statistically meaningful risk factors for suicide. The three major psychiatric diseases, schizophrenia, alcohol abuse, and bipolar disorder, were meaningful in all age groups, but the scale of the odds ratio differed by the age group. Only the psychiatric disorder variable was meaningful in the adolescent group, whereas a psychiatric disorder and economic status were meaningful for the young adult group, and all variables were meaningful for the middle-aged group. A psychiatric disorder and cancer were meaningful in the elderly group, economic status was meaningful for male subjects, and address was meaningful for female subjects. Factors such as living in city or rural areas, low economic status, the presence of a psychiatric disorder, and cancer were statistically meaningful risk factors in suicide. These factors also differed by age group. Therefore, policymakers should establish policies for suicide prevention that are relevant for each age group.

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

Background Visceral leishmaniasis (VL) caused by the protozoan parasite Leishmania donovani causes severe disease. Age appears to be critical in determining the clinical outcome of VL and at present there is no effective vaccine available against VL for any age group. Previously, we showed that genetically modified live attenuated L. donovani parasites (LdCen-/-) induced a strong protective innate and adaptive immune response in young mice. In this study we analyzed LdCen-/- parasite mediated modulation of innate and adaptive immune response in aged mice (18 months) and compared to young (2 months) mice. Methodology Analysis of innate immune response in bone marrow derived dendritic cells (BMDCs) from both young and aged mice upon infection with LdCen-/- parasites, showed significant enhancement of innate effector responses, which consequently augmented CD4+ Th1 cell effector function compared to LdWT infected BMDCs in vitro. Similarly, parasitized splenic dendritic cells from LdCen-/- infected young and aged mice also revealed induction of proinflammatory cytokines (IL-12, IL-6, IFN-γ and TNF) and subsequent down regulation of anti-inflammatory cytokine (IL-10) genes compared to LdWT infected mice. We also evaluated in vivo protection of the LdCen-/- immunized young and aged mice against virulent L. donovani challenge. Immunization with LdCen-/- induced higher IgG2a antibodies, lymphoproliferative response, pro- and anti-inflammatory cytokine responses and stimulated splenocytes for heightened leishmanicidal activity associated with nitric oxide production in young and aged mice. Furthermore, upon virulent L. donovani challenge, LdCen-/- immunized mice from both age groups displayed multifunctional Th1-type CD4 and cytotoxic CD8 T cells correlating to a significantly reduced parasite burden in the spleen and liver compared to naïve mice. It is interesting to note that even though there was no difference in the LdCen-/- induced innate response in dendritic cells

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.

The results of these studies indicated that children younger than 1 year possess the cognitive capability of translating a perception of a novel action into their own behavior. However, the likelihood of imitation varied as a function of the nature of the target behavior. For example, actions requiring direct social commerce with the examiner were imitated less frequently than simple motor behaviors with objects, and reproducing gestures was more common than vocalizations. Moreover, imitation seemed to depend upon the child's level of mental development--the imitation of coordinated sequences, which requires the child to associate two external events, lagged behind the imitation of single-unit behaviors. There was no evidence for individual traits of general imitativeness, at least not until symbolic relations were involved. Live models were imitated more than TV models but only prior to age 3. While children under 2 years of age were not facile at imitating sequences of behaviors or delaying performance at short time after modeling, older toddlers readily and accurately imitated televised sequences even after a 24-hour delay. Whereas socially extroverted and fearless children imitated live models more than shy children, TV imitation was not related to temperament, home TV viewing habits, or parental education. Finally, the experience of being imitated may facilitate the social cognition of influencing another person.

The traditional concept of family in India to provide support to the elderly is changing soon with disintegration of joint families. In this scenario the concept of old age homes (OAHs) is gaining momentum and the number of people seeking OAH care is rapidly increasing. However, not much is known about the quality of life (QOL) of Indian elderly staying in the OAH setup. To assess and compare the Health status, Quality of Life and Depression in elderly people living in OAHs & within family using WHOQOL -OLD questionnaire & Geriatric Depression Scale. A cross sectional study was conducted in elderly aged above 60 years of age. After taking a written consent and matching for age and sex & socioeconomic status, 60 elderly from OAHs & 120 elderly living within family setup were selected randomly. The WHOQOL-OLD standard questionnaire & GDS were used to assess quality of life & depression in elderly. The QOL of elderly in domains of autonomy, past present & future activities, social participation and intimacy was better in family setup (60.62, 70.62, 66.14 and 58.43) as compared to OAHs (51.35, 62.91, 59.47and 41.16) (p<0.05). There was statistically significant difference in mean geriatric depression scores of both the group (3.96 within family setup and 5.76 in OAH's). Quality of life of elderly within family setup was better as compared to elderly in OAHs.

The term "successful aging" appeared in the first issue of "The Gerontologist" in 1961. During the successive years, this expression has changed its meaning. Nowadays, successful aging means "absence of diseases and disabilities, maintenance of high levels of physical and cognitive abilities, preservation of the social and productive activities". It has become a common opinion that the centenarians may represent the prototypes of the successful aging. This motivated our work to study the clinical, psychical, and functional aspects in a centenarian group, verifying the real autonomy, instrumental capacities, and working abilities. Our study pool consisted of 602 centenarians, who were also subjects of then epidemiological studies of the Italian Multicenter Studies on Centenarians (IMUSCE). All subjects underwent a clinical-anamnestic evaluation, cognitive-functional tests by means of the mini mental state examination (MMSE), the independence index in activities of daily living (ADL), the instrumental activities of daily living (IADL) scale. The centenarians were classified in three groups, according to the criteria elaborated previously by us, based on their psychophysical status and autonomy, as follows. Group A: centenarians in good health status; Group B: centenarians in an intermediate health status. Group C: centenarians in bad health status. Group A represented 20.0% of the total pool, Group B amounted to 33.4%, and the Group C was 46.6%. The centenarians of Group A presented normal ADL values, and 47.9% of them were autosufficient in all functions; 5.7% of them were independent in all IADL items. These data confirm that the centenarians of Group A are free of invalidating chronic diseases, are autonomous, maintain good physical and cognitive capacities, however, have not maintained any social or productive activities. Therefore, they cannot be considered as prototypes of successful aging.

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

Overweight or obesity may cause many chronic illnesses. Furthermore, several studies have shown that high body mass index is associated with mortality and morbidity among the elderly. Therefore, obesity or being overweight could adversely affect the performance of activities of daily living. In this study our aim was to investigate the association between Body Mass Index and Activity of Daily Living in Homecare Patients. The records of 2016 from the homecare unit of Sisli Hamidiye Etfal Training and Research Hospital were retrospectively reviewed. During this period, 1105 patients visited this facility. Unconscious or bedridden patients (hemiplegia, hemiparesia, and tetraparesis) and patients with incomplete data were excluded from the study. Therefore, the survey was completed with 250 files, which included all the data needed for our research. Age, gender, Body Mass Index and Barthel Index scores were recorded to the statistical program; p≤0.05 was considered as statistically significant. One hundred fifty one (60.4%) were women, and 99 (39.6%) were men. The relations between gender and age, weight, and Barthel index scores were not statistically significant. There was a significant positive correlation between weight and Barthel index scores as well as between Body Mass Index and Barthel index scores (r = 0.190; p = 0.003). The patients were divided into two groups: Group-I (underweight and normal weight) and Group-II (overweight and obese). Group-II exhibited a much higher ability to perform Activity of Daily Living than Group-I (p = 0.002). Some studies report that obesity is protective against Activity of Daily Living, but the opposite is reported in some others. Our study showed increased values of Body Mass Index and Activity of Daily Living ability, which are indicative of protective effects. The relationship between Body Mass Index and physical disability is not yet proven to be linear.

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.
