Globally, suicide rates increase with age, being highest in older adults. This study analyzed differences in suicides in older adults (65 years and over) compared to middle-aged adults (35-64 years) in Queensland, Australia, during the years 2000-2012. The Queensland Suicide Register was utilized for the analysis. Annual suicide rates were calculated by gender and age group, and odds ratios with 95% confidence intervals were examined. In Queensland, the average annual rate of suicides for older adults was 15.27 per 100,000 persons compared to 18.77 in middle-aged adults in 2000-2012. There were no significant changes in time trends for older adults in 2002-2012. Suicide methods differed between gender and age groups. Older adults who died by suicide were more likely to be male, widowed, living alone or in a nursing home, and out of the work force. The prevalence of untreated psychiatric conditions, diagnosed psychiatric disorders, and consultations with a mental health professional three months prior to death was lower in older adults than middle-aged adults. Somatic illness, bereavement, and attention to suicide in the media were more common among older adults than middle-age adults. Older females were particularly more likely to pay attention to suicide in the media. Our findings show older adults who died by suicide were more likely to experience somatic illnesses, bereavement, and pay attention to suicide in the media compared to middle aged. Preventing suicide in older adults would therefore require holistic and comprehensive approaches.

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

Objectives. Individuals’ perceptions of their own age(ing) are important correlates of well-being and health. The goals of the present study were to (a) examine indicators of self-perceptions of aging across adulthood and (b) experimentally test whether age stereotypes influence self-perceptions of aging. Method. Adults 18–92 years of age were presented with positive, negative, or no age stereotypes. Before and after the stereotype activation, aging satisfaction and subjective age were measured. Results. The activation of positive age stereotypes did not positively influence self-perceptions of aging. Quite the contrary, priming middle-aged and older adults in good health with positive age stereotypes made them feel older. After the activation of negative age stereotypes, older adults in good health felt older and those in bad health wanted to be younger than before the priming. Even younger and middle-aged adults reported younger desired ages after the negative age stereotype priming. Persons in bad health also thought they looked older after being primed with negative age stereotypes. Discussion. Taken together, although we find some support for contrast effects, most of our results can be interpreted in terms of assimilation effects, suggesting that individuals integrate stereotypical information into their self-evaluations of age(ing) when confronted with stereotypes.

Context More than 1.5 million US adults use stimulants and other medications labeled for treatment of attention deficit hyperactivity disorder (ADHD). These agents can increase heart rate and blood pressure, raising concerns about their cardiovascular safety. Objective Examine whether current use of medications used primarily to treat ADHD is associated with increased risk of serious cardiovascular events in young and middle-aged adults. Design Retrospective, population-based cohort study Setting Computerized health records from 4 study sites (OptumInsight Epidemiology, Tennessee Medicaid, Kaiser Permanente California, and the HMO Research Network), starting in 1986 at one site and ending in 2005 at all sites, with additional covariate assessment using 2007 survey data. Participants Adults aged 25–64 years with dispensed prescriptions for methylphenidate, amphetamine, or atomoxetine at baseline. Each medication user (n=150,359) was matched to two non-users on study site, birth year, sex, and calendar year (total users and non-users=443,198). Main Outcome Serious cardiovascular events, including myocardial infarction (MI), sudden cardiac death (SCD), or stroke. Comparison between current or new users and remote users to account for potential healthy user bias. Results During 806,182 person-years of follow-up (median 1.3 years per person), 1357 cases of MI, 296 cases of SCD, and 575 cases of stroke occurred. There were 107,322 person-years of current use (median 0.33 years), with a crude incidence per 1000 person-years of 1.34 (95% CI, 1.14–1.57) for MI, 0.30 (95% CI, 0.20–0.42) for SCD, and 0.56 (95% CI, 0.43–0.72) for stroke. The multivariable adjusted rate ratio (RR) of serious cardiovascular events for current use vs non-use of ADHD medications was 0.83 (95% CI 0.72–0.96). Among new users of ADHD medications, the adjusted RR was 0.77 (95% CI 0.63–0.94). The adjusted RR was 1.03 (95% CI, 0.86–1.24) for current use vs remote use, and was 1.02 (95% CI

Given the global rise in both type 1 diabetes incidence and obesity, the role of body mass index (BMI) on type 1 diabetes pathophysiology has gained great interest. Sustained excess BMI in pediatric participants of the TrialNet Pathway to Prevention (PTP) cohort increased risk for progression to type 1 diabetes, but the effects of age and obesity in adults remain largely unknown. To determine the effect of age and sustained obesity on the risk for type 1 diabetes in adult participants in the TrialNet PTP cohort (i.e., nondiabetic autoantibody-positive relatives of patients with type 1 diabetes). Longitudinally accumulated BMI >25 kg/m2 was calculated to generate a cumulative excess BMI (ceBMI) for each participant, with ceBMI values ≥0 kg/m2 and ≥5 kg/m2 representing sustained overweight or obese status, respectively. Recursive partitioning analysis yielded sex- and age-specific thresholds for ceBMI that confer the greatest risk for type 1 diabetes progression. In this cohort of 665 adults (age 20 to 50 years; median follow-up, 3.9 years), 49 participants developed type 1 diabetes. Age was an independent protective factor for type 1 diabetes progression (hazard ratio, 0.95; P = 0.008), with a threshold of >35 years that reduced risk for type 1 diabetes. In men age >35 years and women age <35 years, sustained obesity (ceBMI ≥5 kg/m2) increased the risk for type 1 diabetes. Age is an important factor for type 1 diabetes progression in adults and influences the impact of elevated BMI, indicating an interplay of excess weight, age, and sex in adult type 1 diabetes pathophysiology.

Isolated Systolic Hypertension in Young and Middle-Aged Adults.

Yano, Yuichiro; Lloyd-Jones, Donald M

2016-11-01

Young and middle-aged adults (ages ≤50 years) are increasingly prone to stroke, kidney disease, and worsening cardiovascular disease (CVD) mortality. An alarming increase in the prevalence of high blood pressure (BP) may underlie the adverse trend. However, there is often uncertainty in BP management for young and middle-aged adults. Isolated systolic hypertension (ISH) is one such example. Whether ISH in young and middle-aged adults represents "pseudo" or "spurious" hypertension is still being debated. ISH in young and middle-aged adults is a heterogeneous entity; some individuals appear to have increased stroke volume, whereas others have stiffened aortae, or both. One size does not seem to fit all in the clinical management of ISH in young and middle-aged adults. Rather than treating ISH as a monolithic condition, detailed phenotyping of ISH based on (patho)physiology and in the context of individual global cardiovascular risks would seem to be most useful to assess an individual expected net benefit from therapy. This review provides an overview of the current understanding of ISH in young and middle-aged adults, including the prevalence, pathophysiology, and treatment.

Studies on 24-hour growth hormone (GH) secretion are rare. The influences of sex, age, and adiposity are well recognized but generally derived from specific, selected subject groups, not spanning sexes, many age decades, and a range of body weights. Our goal was to investigate GH dynamics in a group of 130 healthy adult subjects, both men and women, across 5 age decades as well as a 2.5-fold range of body mass index (BMI) values. GH was measured by a sensitive immunofluorometric assay. Secretion parameters were quantified by automated deconvolution and relative pattern randomness by approximate entropy (ApEn). The median age was 40 years (range 20-77). The median BMI was 26 (range 18.3-49.8). Pulsatile 24-hour GH secretion was negatively correlated with age (p = 0.002) and BMI (p < 0.0001). Basal GH secretion negatively correlated with BMI (p = 0.003) but not with age. The sex- dependent GH secretion (greater in women) was no longer detectable after 50 years of age. Insulin-like growth factor (IGF)-1 levels were lower in women over 50 years of age compared with men of a similar age. ApEn showed an age-related increase in both sexes and was higher in premenopausal and postmenopausal women than in men of comparable age (p < 0.0001). A single fasting GH measurement is not informative of 24-hour GH secretion. BMI dominates the negative regulation of 24-hour GH secretion across 5 decades of age in this up till now largest cohort of healthy adults who underwent 24-hour blood sampling. Sex also impacts GH secretion before the age of 50 years as well as its regularity at all ages. Differences in serum IGF-1 partly depend on the pre- or postmenopausal state. Finally, a single GH measurement is not informative of 24-hour GH secretion. © 2015 S. Karger AG, Basel.

Antiaging therapies show promise in model organism research. Translation to humans is needed to address the challenges of an aging global population. Interventions to slow human aging will need to be applied to still-young individuals. However, most human aging research examines older adults, many with chronic disease. As a result, little is known about aging in young humans. We studied aging in 954 young humans, the Dunedin Study birth cohort, tracking multiple biomarkers across three time points spanning their third and fourth decades of life. We developed and validated two methods by which aging can be measured in young adults, one cross-sectional and one longitudinal. Our longitudinal measure allows quantification of the pace of coordinated physiological deterioration across multiple organ systems (e.g., pulmonary, periodontal, cardiovascular, renal, hepatic, and immune function). We applied these methods to assess biological aging in young humans who had not yet developed age-related diseases. Young individuals of the same chronological age varied in their “biological aging” (declining integrity of multiple organ systems). Already, before midlife, individuals who were aging more rapidly were less physically able, showed cognitive decline and brain aging, self-reported worse health, and looked older. Measured biological aging in young adults can be used to identify causes of aging and evaluate rejuvenation therapies. PMID:26150497

Adequate lifelong calcium intake is essential in optimizing bone health. Recent National Health and Nutrition Examination Survey data were used to quantify variation in calcium intake across adult age groups and to relate age-associated changes in calcium intake with energy intake. Additional goals were to assess differences in dietary calcium intake between supplemental calcium users and nonusers and to evaluate associations between age and calcium density in the diet. This cross-sectional analysis determined calcium and energy intake for National Health and Nutrition Examination Survey respondents during 2003-2006. Diet was assessed with 24-hour recall and supplement use via questionnaire. Trends in median intakes for dietary calcium, total calcium, and energy across age categories were assessed using survey analysis methods. Nutrient density was represented using calcium to energy intake ratios. The analyses included data from 9,475 adults. When compared to the 19- to 30-year age group, median dietary calcium intake was lower in the ≥81-year age group by 23% in men (P<0.001) and by 14% in women (P=0.003). These reductions coincided with 35% and 28% decreases, respectively, in median energy intake (P<0.001 for each sex). In contrast, the frequency of calcium supplement use increased (P<0.001) with age in both men and women. Yet, among female supplement users, the decline in median dietary calcium intake was greater than in nonusers (P=0.02). Calcium density in the diet significantly increased relative to age in men and women (P<0.001 for each sex); however, dietary and total calcium to energy ratios were insufficient to meet target ratios inferred by adequate intake standards after age 50 years. Although supplemental calcium use and calcium density were highest in older age groups, they were not sufficient in meeting recommended levels. New approaches to increasing the frequency and level of calcium supplement use to enhance calcium density in diets may be

Background Despite the increasing interest towards the biological role of L-ergothioneine, little is known about the serum concentrations of this unusual aminothiol in older adults. We addressed this issue in a representative sample of community-dwelling middle-aged and older adults. Methods Body mass index, estimated glomerular filtration rate, serum concentrations of L-ergothioneine, taurine, homocysteine, cysteine, glutathione, cysteinylglycine, and glutamylcysteine were evaluated in 439 subjects (age 55–85 years) randomly selected from the Hunter Community Study. Results Median L-ergothioneine concentration in the entire cohort was 1.01 IQR 0.78–1.33 µmol/L. Concentrations were not affected by gender (P = 0.41) or by presence of chronic medical conditions (P = 0.15). By considering only healthy subjects, we defined a reference interval for L-ergothioneine serum concentrations from 0.36 (90% CI 0.31–0.44) to 3.08 (90% CI 2.45–3.76) µmol/L. Using stepwise multiple linear regression analysis L-ergothioneine was negatively correlated with age (rpartial = −0.15; P = 0.0018) and with glutamylcysteine concentrations (rpartial = −0.13; P = 0.0063). Conclusions A thorough analysis of serum L-ergothioneine concentrations was performed in a large group of community-dwelling middle-aged and older adults. Reference intervals were established. Age and glutamylcysteine were independently negatively associated with L-ergothioneine serum concentration. PMID:24392160

Objectives: to examine perceived age discrimination in a large representative sample of older adults in England. Methods: this cross-sectional study of over 7,500 individuals used data from the fifth wave of the English Longitudinal Study of Ageing (ELSA), a longitudinal cohort study of men and women aged 52 years and older in England. Wave 5 asked respondents about the frequency of five everyday discriminatory situations. Participants who attributed any experiences of discrimination to their age were treated as cases of perceived age discrimination. Multivariable logistic regression analysis was used to estimate the odds ratios of experiencing perceived age discrimination in relation to selected sociodemographic factors. Results: approximately a third (33.3%) of all respondents experienced age discrimination, rising to 36.8% in those aged 65 and over. Perceived age discrimination was associated with older age, higher education, lower levels of household wealth and being retired or not in employment. The correlates of age discrimination across the five discriminatory situations were similar. Conclusion: understanding age discrimination is vital if we are to develop appropriate policies and to target future interventions effectively. These findings highlight the scale of the challenge of age discrimination for older adults in England and illustrate that those groups are particularly vulnerable to this form of discrimination.

Indicators of abdominal size relative to height associated with sex, age, socioeconomic position and ancestry among US adults.

The supine sagittal abdominal diameter (SAD) and standing waist circumference (WC) describe abdominal size. The SAD/height ratio (SADHtR) or WC/height ratio (WHtR) may better identify cardiometabolic disorders than BMI (weight/height2), but population-based distributions of SADHtR and WHtR are not widely available. Abdominal adiposity may differ by sociodemographic characteristics. Anthropometry, including SAD by sliding-beam caliper, was performed on 9894 non-pregnant adults ≥20 years in the US National Health and Nutrition Examination Surveys of 2011-2014. Applying survey design factors and sampling weights, we estimated nationally representative SADHtR and WHtR distributions by sex, age, educational attainment, and four ancestral groups. The median (10th percentile, 90th percentile) for men's SADHtR was 0.130 (0.103, 0.165) and WHtR 0.569 (0.467, 0.690). For women, median SADHtR was 0.132 (0.102, 0.175) and WHtR 0.586 (0.473, 0.738). Medians for SADHtR and WHtR increased steadily through age 79. The median BMI, however, reached maximum values at ages 40-49 (men) or 60-69 (women) and then declined. Low educational attainment, adjusted for age and ancestry, was associated with elevated SADHtR more strongly than elevated BMI. While non-Hispanic Asians had substantially lower BMI compared to all other ancestral groups (adjusted for sex, age and education), their relative reductions in SADHtR and WHtR, were less marked. These cross-sectional data are consistent with monotonically increasing abdominal adipose tissue through the years of adulthood but decreasing mass in non-abdominal regions beyond middle age. They suggest also that visceral adipose tissue, estimated by SADHtR, expands differentially in association with low socioeconomic position. Insofar as Asians have lower BMIs than other populations, employing abdominal indicators may attenuate the adiposity differences reported between ancestral groups.

The role of subclinical hypothyroidism in the development of depression remains controversial. We examined the prospective association between subclinical hypothyroidism and incident depressive symptoms. We conducted a prospective cohort study of 220,545 middle-age adults without depression who had undergone at least two comprehensive health examinations between 1 January 2011 and 31 December 2014. Thyroid-stimulating hormone, free triiodothyronine (FT3), and free thyroxine (FT4) levels were measured using an electrochemiluminescent immunoassay. The study outcome was incident depressive symptoms, defined as a Center for Epidemiologic Studies-Depression score >16. During a median follow-up period of 2 years, incident depressive symptoms occurred in 7323 participants. The multivariable-adjusted hazard ratio for incident depressive symptoms comparing subclinical hypothyroid and euthyroid participants was 0.97 (95% confidence interval, 0.87 to 1.09). Similarly, among euthyroid participants (n = 87,822), no apparent association was found between thyroid hormone levels and an increased risk of incident depressive symptoms. No apparent association was found between subclinical hypothyroidism and incident depressive symptoms in a large prospective cohort of middle-age men and women.

Accumulating evidence has demonstrated a pathogenic role of advanced glycation end products (AGEs) and receptors for AGEs (RAGE) in inflammation. Soluble RAGE (sRAGE), with the same ligands-binding capacity as full-length RAGE, acts as a "decoy" receptor. However, there has been scanty data regarding AGEs and sRAGE in adult-onset Still's disease (AOSD). This study aimed to investigate AGEs and sRAGE levels in AOSD patients and examine their association with clinical characteristics. Using ELISA, plasma levels of AGEs and sRAGE were determined in 52 AOSD patients, 36 systemic lupus erythematosus(SLE) patients and 16 healthy controls(HC). Their associations with activity parameters and disease courses were evaluated. Significantly higher median levels of AGEs were observed in active AOSD patients (16.75 pg/ml) and active SLE patients (14.80 pg/ml) than those in HC (9.80 pg/ml, both p < 0.001). AGEs levels were positively correlated with activity scores (r = 0.836, p < 0.001), ferritin levels (r = 0.372, p < 0.05) and CRP levels (r = 0.396, p < 0.005) in AOSD patients. Conversely, significantly lower median levels of sRAGE were observed in active AOSD patients (632.2 pg/ml) and active SLE patients (771.6 pg/ml) compared with HC (1051.7 pg/ml, both p < 0.001). Plasma sRAGE levels were negatively correlated with AOSD activity scores (r = -0.320, p < 0.05). In comparison to AOSD patients with monocyclic pattern, significantly higher AGEs levels were observed in those with polycyclic or chronic articular pattern. With treatment, AGEs levels declined while sRAGE levels increased in parallel with the decrease in disease activity. The elevation of AGEs levels with concomitant decreased sRAGE levels in active AOSD patients, suggests their pathogenic role in AOSD.

There is a lack of standardized and quantifiable measures of touch function, for clinical work. Furthermore, it is not possible to make accurate diagnostic judgments of touch function before normative values are estimated. The objectives of this study were to establish adult norms of the perceptual threshold of touch (PTT) for the hands and feet according to age and gender and to determine the effect of right/left side, handedness, height, weight, and body mass index (BMI) on the PTT. The PTT was assessed by using a high-frequency transcutaneous electrical nerve stimulator (Hf/TENS) with self-adhesive skin electrodes in 346 adults. The PTT was identified as the level registered in mA at which the participants perceived a tingling sensation. The PTT for all participants was a median of 3.75 mA (range 2.50-7.25) in the hands and a median of 10.00 (range 5.00-30.00) in the feet. With increasing age an increase of the PTT was found. Men reported higher PTT than women. The right hand had higher PTT than the left. Handedness, height, weight, and BMI did not affect the PTT. Adult norms of the PTT in the hands for age, gender, and right/left side are presented for four age groups. The present study's estimate of the PTT in the hands could be used as adult norms. Adult norms for the feet could not be estimated because the PTT values in the feet showed a great variance.

Theory of mind (ToM), or the ability to understand mental states, is a fundamental aspect of social cognition. Previous research has documented marked advances in ToM in preschoolers, and declines in ToM in older-aged adults. In the present study, younger (n=37), middle-aged (n=20), and older (n=37) adults completed a continuous false belief task measuring ToM. Middle-aged and older adults exhibited more false belief bias than did younger adults, irrespective of language ability, executive function, processing speed, and memory. The authors conclude that ToM declines from younger to older adulthood, independent of age-related changes to domain-general cognitive functioning.

The purposes of this study were to examine age and gender differences in throwing performance across an underexplored portion of the lifespan: middle adolescents (14-17 years old), young adults (18-25 years old), and adults (35-55 years old). Throwing performance was assessed using the body component levels from Roberton's developmental sequences for force and ball velocity that were recorded by a radar gun. Participants in each age group performed between 5 to 10 forceful overhand throws toward a target approximately 15m to 20m from the thrower. A Wilcoxon-Mann-Whitney Test was used to determine gender differences and a Wilcoxon-Signed Ranks Test was used to determine age-group differences for each component. Gender and age-group differences in ball speed were determined by a 3 (age group) x 2 (gender) factorial analysis of variance with follow-up post-hoc tests. Young-adult men had higher body component levels and ball speed compared with the adolescent boys and adult men. Female age-group differences existed only for humerus action between young-adult and adult groups and for ball speed between young-adult and adolescent groups. Gender differences (p < .01) existed in component levels for the adolescent and young-adult groups, but not the adult groups. Gender differences in ball speed (p < .001) existed within each age group. Although these data were cross-sectional, the regressive developmental changes observed and the narrowing gender gap may eventually provide insight related to the relationships among motor skill competence, physical fitness, and physical activity across the lifespan.

Numerous studies have focused on the diversity of audiovisual integration between younger and older adults. However, consecutive trends in audiovisual integration throughout life are still unclear. In the present study, to clarify audiovisual integration characteristics in middle-aged adults, we instructed younger and middle-aged adults to conduct an auditory/visual stimuli discrimination experiment. Randomized streams of unimodal auditory (A), unimodal visual (V) or audiovisual stimuli were presented on the left or right hemispace of the central fixation point, and subjects were instructed to respond to the target stimuli rapidly and accurately. Our results demonstrated that the responses of middle-aged adults to all unimodal and bimodal stimuli were significantly slower than those of younger adults (p < 0.05). Audiovisual integration was markedly delayed (onset time 360 ms) and weaker (peak 3.97%) in middle-aged adults than in younger adults (onset time 260 ms, peak 11.86%). The results suggested that audiovisual integration was attenuated in middle-aged adults and further confirmed age-related decline in information processing.

Older adults report greater emotional well-being than younger persons, yet negative stereotypes about aging are pervasive. Little is known about age group perceptions of emotion in adulthood, particularly for familiar persons. Thus, this project determined perceptions of general affect in familiar younger and older adults. In two studies, participants (Study 1, younger adult n = 123, older adult n = 43; Study 2, younger adult n = 34, midlife adult n = 41, older adult n = 16) provided self-report data about their affect in general, as well as reported on the affect of a familiar younger person (aged 18--34) and a familiar older person (aged 65 or older). Emotion scales assessed high- and low-arousal positive and negative affect. Results suggest a less favorable perception of emotion experiences of older adults compared to younger adults. Specifically, participants of all age groups rated older adults as having lower positive emotions and higher negative emotions than is found in self-report data. Perceptions of emotion in older adulthood reflect stereotypes of negative functioning. Older adult participants were not immune to holding negative views about older adults. Negative perceptions about emotion experiences in later life may be detrimental to the physical and mental health of older adults.

Older Adults' Online Dating Profiles and Successful Aging.

This study examined how relevant Rowe and Kahn's three criteria of successful aging were to older adults' self-portrayals in online dating profiles: low probability of disease and disability, high functioning, and active life engagement. In this cross-sectional study, 320 online dating profiles of older adults were randomly selected and coded based on the criteria. Logistic regression analyses determined whether age, gender, and race/ethnicity predicted self-presentation. Few profiles were indicative of successful aging due to the low prevalence of the first two criteria; the third criterion, however, was identified in many profiles. Native Americans were significantly less likely than other ethnic groups to highlight the first two criteria. Younger age predicted presenting the first criterion. Women's presentation of the third criterion remained significantly high with age. The findings suggest that the criteria may be unimportant to older adults when seeking partners, or they may reflect the exclusivity of this construct.

Examining aging sexual stigma attitudes among adults by gender, age, and generational status.

Stigma related to later life sexuality could produce detrimental effects for older adults, through individual concerns and limited sexual health care for older adults. Identifying groups at risk for aging sexual stigma will help to focus interventions to reduce it. Accordingly, the purpose of this study was to examine cross-sectional trends in aging sexual stigma attitudes by age group, generational status, and gender. An online survey was administered to a national sample of adults via a crowdsourcing tool, in order to examine aging sexual stigma across age groups, generational status, and gender (N = 962; 47.0% male, 52.5% female, and .5% other; mean age = 45 years). An aging sexual stigma index was formulated from the attitudinal items of the Aging Sexual Knowledge and Attitudes Scale. This sample reported moderately permissive attitudes toward aging sexuality, indicating a low level of aging sexual stigma. Though descriptive data showed trends of stigma attitudes increasing with age and later generations, there were no significant differences between age groups or generations in terms of aging sexual stigma beliefs. Men, regardless of age and/or generation, were found to espouse significantly higher stigmatic beliefs than women or those reporting 'other' gender. Aging sexual stigma beliefs may not be prevalent among the general population as cohorts become more sexually liberal over time, though men appear more susceptible to these beliefs. However, in order to more comprehensively assess aging sexual stigma, future research may benefit from measuring explicit and implicit aging sexual stigma beliefs.

Limited systematic data are available on prescription and dosing of haemodialysis (HD) in children and adolescents compared with adults. We aimed to characterize age- and weight-based differences in HD delivery in children, adolescents and young adults. This is a retrospective observational study including 1852 patients <30 years on chronic HD from childhood (53 903 HD sessions), receiving thrice weekly outpatient HD between 2004 and 2016 in the USA (6075 patient-years, of which 2535 were in patients aged 1-18 years; weight range 8.3-168 kg). Median individual prescriptions per year were calculated and overall 50% (IQR) and 90% distribution ranges over age and weight were derived. Repeated measurements analysis of variance assessed differences between age and weight groups. Prescriptions significantly differed among age and weight groups (P < 0.001). Lower weight patients (<75 kg) had higher (inter-quartile range, IQR) weight-normalized blood flow rate (highest in <25 kg: QB/kg = 6.5-9.1 mL/min/kg), urea dialytic clearance (KD/kg) and single pool Kt/V (spKt/V) (<25 kg: 1.43-1.78; 25-50 kg: 1.52-1.92; 50-75 kg: 1.43-1.74) than heavier patients (lowest in >100 kg: QB/kg = 3.1-4.0 mL/min/kg, spKt/V = 1.22-1.47, respectively). Adolescents had significantly lower QB/kg, KD/kg and spKt/V (1.34-1.71) compared with adults (1.45-1.79) and children <12 years (range of 25th percentiles: 1.37-1.44). Dialytic clearance derived from a mechanistic equation underpredicted KD in children but not in young adults. Significant growth retardation was observed, with the proportion of patients <3rd percentile (height for age) decreasing from 71% (1-2 years) to 15% (>18 years). Delivered HD treatment varies with age and weight and is more intensified in children aged <12 years, compared with adolescents and overweight young adults, who appear to be at highest risk of receiving suboptimal treatment. Still, delivery of target or higher sp

Thymectomy is performed routinely in infants undergoing cardiothoracic surgery. Children post-sternotomy have decreased numbers of T lymphocytes, although the mechanisms involved and long-term consequences of this have not been defined. We hypothesized that lymphopenia in patients with adult congenital heart disease (ACHD) would be reflective of premature T cell maturation and exhaustion. Adults with ACHD who had sternotomy to repair congenital heart disease as infants (<1 year) and age-matched ACHD patients without prior sternotomy were studied using polychromatic flow cytometry interrogating markers of lymphocyte maturation, exhaustion and senescence. Group differences were analyzed using Mann-Whitney U and Fisher's exact tests. Eighteen ACHD patients aged 21-40 years participated: 10 cases and 8 controls. Median age at sternotomy for cases was 52 days. Cases and controls were matched for age (28.9 vs. 29.1 years; p = 0.83), gender (p = 0.15) and race (p = 0.62) and had similar case complexity. Cases had a lower mean percentage of cytotoxic CD8 lymphocytes compared to controls (26.8 vs. 33.9 %; p = 0.016), with fewer naive, undifferentiated CD8 T cells (31.0 vs. 53.6 %; p = 0.027). CD8 cells expressing PD1, a marker of immune exhaustion, trended higher in cases versus controls (25.6 vs. 19.0 %; p = 0.083). Mean percentage of CD4 cells was higher in cases versus controls (65.6 vs. 59.6 %; p = 0.027), without differences in CD4 T cell maturation subtype. In summary, ACHD patients who undergo sternotomy as infants exhibit differences in T lymphocyte composition compared to ACHD controls, suggesting accelerated immunologic exhaustion. Investigation is warranted to assess the progressive nature and clinical impact of this immune phenotypic change.

Aortic diameter is an imperfect predictor of aortic complications in connective tissue disorders (CTDs). Novel indicators of vascular phenotype severity such as aortic stiffness and vertebral tortuosity index have been proposed. We assessed the relation between aortic stiffness by cardiac MRI, surgical root replacement, and rates of aortic root dilation in children and young adults with CTDs. Retrospective analysis of cardiac MRI data on children and young adults with a CTD was performed to derive aortic stiffness measures (strain, distensibility, and β-stiffness index) at the aortic root, ascending aorta, and descending aorta. Vertebral tortuosity index was calculated as previously described. Rate of aortic root dilation before cardiac MRI was calculated as change in echocardiographic aortic root diameter z score per year. In 83 CTD patients (median age, 24 years; range, 1-55; 17% <18 years of age; 60% male), ascending aorta distensibility was reduced in comparison with published normative values: median z score, -1.93 (range, -8.7 to 1.3; P<0.0001 versus normals). Over a median follow-up period of 2.7 years, there were no aortic dissections or deaths, but 16 of 83 (19%) patients underwent surgical aortic root replacement. In multivariable analysis, lower aortic root strain (P=0.05) and higher vertebral tortuosity index (P=0.01) were independently associated with aortic root replacement. Lower ascending aorta strain (P=0.02) was associated with a higher rate of aortic root dilation. Higher aortic stiffness is associated with higher rates of surgical aortic replacement and aortic root dilation in children and young adults with CTDs. © 2015 American Heart Association, Inc.

Clinical Characteristics of Adult Dogs More Than 5 Years of Age at Presentation for Patent Ductus Arteriosus.

The median age at presentation for dogs with patent ductus arteriosus (PDA) is <6 months of age, and closure is associated with a decrease in heart size and increased survival time, which are not well described in older dogs. To describe the clinical characteristics of dogs with PDA ≥5 years of age at the time of presentation to a veterinary referral hospital. 35 client-owned dogs. Retrospective case series. PDA was diagnosed at a median age of 7.4 years (range, 5.1-12.3 years). Females represented 23/35 (65.7%) of the patients. Concurrent heart disease included degenerative mitral valve disease (DMVD; 13), arrhythmias (11), pulmonary hypertension (7), and other congenital defects (2). Cardiomegaly was documented in the majority of dogs consisting of left ventricular enlargement (91%) and left atrial enlargement (86%). Median vertebral heart size in 24 dogs was 12.9 (range, 10.7-18.2). The PDA shunt direction was left-to-right in 33 and bidirectional in 2 dogs. Closure was performed in 26 dogs, including 4 with pulmonary hypertension. In 10 dogs receiving furosemide pre-operatively for management of heart failure, furosemide was discontinued (8) or the dosage decreased (2) at the time of discharge. Adult dogs can present with a left-to-right shunting PDA that results in cardiomegaly and clinical signs that can improve or resolve with PDA closure. This improvement is also apparent in dogs with PDA complicated by DMVD. Pulmonary hypertension that does not result in complete right-to-left shunting should not be considered a contraindication to closure. Copyright © 2017 The Authors.

This study compared levels of physical activity completed by adults with and without Down syndrome. Fifteen adults with and 15 adults without Down syndrome matched for age and gender, took part. The intensity and duration of physical activity were measured using RT3 accelerometers worn for seven days. Only, 12 participants with Down syndrome had complete physical activity data, and these participants and their matched controls (total: six females, 18 males; aged 25.8 ± 9.7) were included in the analyses. There were significantly lower levels of moderate and vigorous physical activity per day for people with Down syndrome (median = 27 min) compared to those without (median = 101 min) (p < .001). Participants without disability were twice more likely to achieve recommended levels of physical activity than people with Down syndrome. Adults with Down syndrome appear to participate in lower levels of physical activity than adults without Down syndrome. Further research should validate these estimates. © 2017 John Wiley & Sons Ltd.

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

It has been observed that subjective age (SA) often trails chronological age, especially in older adults. In a previously published article, we argued that differences in individual's SA is a function of their level of activity on biological, mental, and social dimensions. This article empirically tests this proposition using a newly created Subjective Aging Index (SAI). The SAI is related to SA above the effect of age with differences existing across age groups and sex. The findings contribute to the literature on successful aging strategies with important implications for health care practitioners, marketers, and individuals heading towards older adult years.

Objectives This study aimed to determine the prevalence of suicidal ideation among young and middle-aged adults, and explore the risk factors that affect suicidal ideation. Methods A descriptive study design was used for secondary data analysis. A total sample of 5,214 was drawn from two waves (2012–2013) of the 7th Korea Health Panel (KHP) survey. The KHP data were collected by a well-trained interviewer using the face-to-face method during home visits as well as self-report method. Descriptive statistics of frequency, percentage, chi-square test, and logistic regression analysis were performed using SPSS 22.0. Results The prevalence of suicidal ideation in young and middle-aged adults was 4.4% and 5.6%, respectively. For young adults, suicidal ideation risk was higher among those with low income or heavy drinking habits. In middle-aged adults, low income, poor perceived health status, negative perception of peer-compared health status, and negative social perspective were the major risk factors. Conclusion There is considerable risk of suicidal ideation in adulthood. Opportunities for increased income, avoidance of heavy drinking, and the construction of positive subjective health status and social perspective should be considered in suicide prevention interventions for Korean young and middle-aged adults.

Face Age and Eye Gaze Influence Older Adults' Emotion Recognition.

PubMed

Campbell, Anna; Murray, Janice E; Atkinson, Lianne; Ruffman, Ted

2017-07-01

Eye gaze has been shown to influence emotion recognition. In addition, older adults (over 65 years) are not as influenced by gaze direction cues as young adults (18-30 years). Nevertheless, these differences might stem from the use of young to middle-aged faces in emotion recognition research because older adults have an attention bias toward old-age faces. Therefore, using older face stimuli might allow older adults to process gaze direction cues to influence emotion recognition. To investigate this idea, young and older adults completed an emotion recognition task with young and older face stimuli displaying direct and averted gaze, assessing labeling accuracy for angry, disgusted, fearful, happy, and sad faces. Direct gaze rather than averted gaze improved young adults' recognition of emotions in young and older faces, but for older adults this was true only for older faces. The current study highlights the impact of stimulus face age and gaze direction on emotion recognition in young and older adults. The use of young face stimuli with direct gaze in most research might contribute to age-related emotion recognition differences. © The Author 2015.

Predictors of Prosocial Behavior: Differences in Middle Aged and Older Adults.

PubMed

Wenner, Jennifer R; Randall, Brandy A

2016-10-01

Generativity, contributing to the next generation, is important for well-being throughout middle and late life. Therefore, it is crucial to understand what contributes to generativity during these life stages. Parenting and work are common, but not the only, ways people engage generatively; prosocial behavior is another. A community connection may encourage generative contributions in adults. However, older adults may face obstacles to being generative, and may need an additional drive to engage in these behaviors. Given this, it was expected that community cohesion would predict prosocial behavior despite age, and that grit would provide motivation for older adults, so the current study examined whether age moderated the relation between grit and prosocial behavior. Data were used from 188 upper-Midwest adults (aged 37-89). Multiple regression analyses showed that age moderated the relation between grit and prosocial behavior such that grit predicted prosocial behavior in older adults but not middle age adults. A sense of community cohesion was predictive of prosocial behavior despite age. While grit may promote generative acts in different ways depending on age, a sense of community cohesion may foster community contributions despite age. The discussion focuses on future directions and ways to promote generativity using this research.

Age-Related Gene Expression Differences in Monocytes from Human Neonates, Young Adults, and Older Adults

Tong, Ann-Jay; Kollmann, Tobias R.; Smale, Stephen T.

2015-01-01

A variety of age-related differences in the innate and adaptive immune systems have been proposed to contribute to the increased susceptibility to infection of human neonates and older adults. The emergence of RNA sequencing (RNA-seq) provides an opportunity to obtain an unbiased, comprehensive, and quantitative view of gene expression differences in defined cell types from different age groups. An examination of ex vivo human monocyte responses to lipopolysaccharide stimulation or Listeria monocytogenes infection by RNA-seq revealed extensive similarities between neonates, young adults, and older adults, with an unexpectedly small number of genes exhibiting statistically significant age-dependent differences. By examining the differentially induced genes in the context of transcription factor binding motifs and RNA-seq data sets from mutant mouse strains, a previously described deficiency in interferon response factor-3 activity could be implicated in most of the differences between newborns and young adults. Contrary to these observations, older adults exhibited elevated expression of inflammatory genes at baseline, yet the responses following stimulation correlated more closely with those observed in younger adults. Notably, major differences in the expression of constitutively expressed genes were not observed, suggesting that the age-related differences are driven by environmental influences rather than cell-autonomous differences in monocyte development.

Social Security: a financial appraisal for the median voter.

PubMed

Galasso, V

Several explanations have been proposed for why voters continue to support unfunded social security systems. Browning (1975) suggests that the extremely large unfunded pension systems of most democracies depend on the existence of a voting majority composed of middle-aged and older people who fail to fully internalize the cost of financing the system. In fact, when voting, economically rational workers consider only their current and future contributions to the system and their expected pension benefits--not their past contributions, which they regard as sunk costs. If, for a majority of voters, the expected continuation return from social security exceeds the return from alternative assets, an unfunded social security system is politically sustainable. This article explores the validity of Browning's proposition by quantifying the returns that U.S. voters in presidential elections from 1964 to 1996 have obtained, or expect to obtain, from Social Security. Did "investments" in Social Security outperform alternative forms of investment, such as mutual funds or pension funds, for a majority of the voters? What can be expected for the future? The U.S. Social Security system redistributes income within age cohorts on the basis of sex, income, and marital status. To account for some of these features, the median voter is represented by a family unit whose members--a husband who accounts for 70 percent of household earnings and a wife who accounts for 30 percent--make joint economic and voting decisions. Thus, retirement and survival benefits paid out to the spouse of an insured worker can be included in the calculation of Social Security returns. Interval estimates of voters' family incomes from the U.S. Census Bureau were used to obtain the median voter's household earnings. The median voter's age is derived from the ages of those who voted in presidential elections, not from the ages of the entire electorate. The median voter's contributions to Social Security are the

Gaze-following behaviour is considered crucial for social interactions which are influenced by social similarity. We investigated whether the degree of similarity, as indicated by the perceived age of another person, can modulate gaze following. Participants of three different age-groups (18-25; 35-45; over 65) performed an eye movement (a saccade) towards an instructed target while ignoring the gaze-shift of distracters of different age-ranges (6-10; 18-25; 35-45; over 70). The results show that gaze following was modulated by the distracter face age only for young adults. Particularly, the over 70 year-old distracters exerted the least interference effect. The distracters of a similar age-range as the young adults (18-25; 35-45) had the most effect, indicating a blurred own-age bias (OAB) only for the young age group. These findings suggest that face age can modulate gaze following, but this modulation could be due to factors other than just OAB (e.g., familiarity).

To assess the effect of aging on the immunological response to antiretroviral therapy (ART) in the West African context. The change in CD4 T-cell count was analysed according to age at the time of ART initiation among HIV-infected patients enrolled in the International epidemiological Database to Evaluate AIDS (IeDEA) Collaboration in the West African region. CD4 gain over 12 months of ART was estimated using linear mixed models. Models were adjusted for baseline CD4 cell count, sex, baseline clinical stage, calendar period and ART regimen. The total number of patients included was 24,107, contributing for 50,893 measures of CD4 cell count in the first year of ART. The baseline median CD4 cell count was 144 cells/μl [interquartile range (IQR) 61-235]; median CD4 cell count reached 310 cells/μl (IQR 204-443) after 1 year of ART. The median age at treatment initiation was 36.3 years (10th-90th percentiles = 26.5-50.1). In adjusted analysis, the mean CD4 gain was significantly higher in younger patients (P < 0.0001). At 12 months, patients below 30 years recovered an additional 22 cells/μl on average [95% confidence interval (CI) 2-43] compared to patients at least 50 years. Among HIV-infected adults in West Africa, the immunological response after 12 months of ART was significantly poorer in elderly patients. As the population of treated patients is likely to get older, the impact of this age effect on immunological response to ART may increase over time.

Descriptive study. To determine the presence of median and ulnar neuropathies in both upper extremities of university guitarists. Peripheral nerve entrapment syndromes of the upper extremities are well documented in musicians. Guitarists and plucked-string musicians are at risk for entrapment neuropathies in the upper extremities and are prone to mild neurologic deficits. Twenty-four volunteer male and female guitarists (age range, 18-26 years) were recruited from the Belmont University School of Music and the Vanderbilt University Blair School of Music. Individuals were excluded if they were pregnant or had a history of recent upper extremity or neck injury. Subjects completed a history form, were interviewed, and underwent a physical examination. Nerve conduction status of the median and ulnar nerves of both upper extremities was obtained by performing motor, sensory, and F-wave (central) nerve conduction studies. Descriptive statistics of the nerve conduction study variables were computed using Microsoft Excel. Six subjects had positive findings on provocative testing of the median and ulnar nerves. Otherwise, these guitarists had normal upper extremity neural and musculoskeletal function based on the history and physical examinations. When comparing the subjects' nerve conduction study values with a chart of normal nerve conduction studies values, 2 subjects had prolonged distal motor latencies (DMLs) of the left median nerve of 4.3 and 4.7 milliseconds (normal, < 4.2 milliseconds). Prolonged DMLs are compatible with median neuropathy at or distal to the wrist. Otherwise, all electrophysiological variables were within normal limits for motor, sensory, and F-wave (central) values. However, comparison studies of median and ulnar motor latencies in the same hand demonstrated prolonged differences of greater than 1.0 milliseconds that affected the median nerve in 2 additional subjects, and identified contralateral limb involvement in a subject with a prolonged

Brown adipose tissue (BAT) is present and functions to dissipate energy as heat in young adults and can be assessed using magnetic resonance imaging (MRI) to estimate the voxel fat fraction, i.e. proton density fat fraction (PDFF). It is hypothesized that subjects born preterm or small for gestational age (SGA) may exhibit disrupted BAT formation coupled to metabolic factors. Our purpose was to assess the presence of BAT in young adults born extremely preterm or SGA in comparison with controls. We studied 30 healthy subjects (median age, 21 years): 10 born extremely preterm, 10 full term but SGA and 10 full term with a normal birth weight (controls). We utilized an MRI technique combining multiple scans to enable smaller echo spacing and an advanced fat-water separation method applying graph cuts to estimate B0 inhomogeneity. We measured supraclavicular/cervical PDFF, R2*, fat volume, insulin-like growth factor 1, glucagon, thyroid stimulating hormone and the BAT-associated hormones fibroblast growth factor 21 and irisin. The groups did not significantly differ in supraclavicular/cervical PDFF, R2*, fat volume or hormone levels. The mean supraclavicular/cervical PDFF was equivalent between the groups (range 75-77%). Young adults born extremely preterm or SGA show BAT development similar to those born full term at a normal birth weight. Thus, the increased risk of cardiovascular and metabolic disorders in these groups is not due to the absence of BAT, although our results do not exclude possible BAT involvement in this scenario. Larger studies are needed to understand these relationships.

Previous studies found positive influences of videogame playing on cognition. However, the age-related and task-related effects of videogame experience across the adult life span are still unknown. The current study aimed to systematically investigate this question. The current study used the cross-sectional approach. A total of 166 participants (84 videogame players [VGPs], 82 nonvideogame players [NVGPs]) at the age of 18-80 in the present study were recruited, including 62 young adults aged from 18 to 34 (35 VGPs, 27 NVGPs), 55 middle-aged adults aged between 35 and 59 (24 VGPs, 31 NVGPs), and 49 older adults aged between 60 and 80 (25 VGPs, 24 NVGPs). 1,2 A series of neuropsychological tests from different cognitive domains, including processing speed, visuospatial, attention, memory, and executive function, were conducted on participants. The age-related effects demonstrated that young and older adults benefited more from videogame experience than middle-aged adults. The task-related effects showed that VGPs benefited more from videogame experience in processing speed and visuospatial processing; next was executive function and attention, while no benefits in memory. The effect sizes suggested that the difference in extent between VGPs and NVGPs in processing speed and visuospatial processing is moderate, in attention and executive function is small, and in memory is negligible. The current findings support the beneficial effects and transfer effects of videogame experience; however, the effects presented age-specific and task-specific characteristics. The results provide useful insights for future videogame intervention studies for healthy adults of different ages.

This study aimed to evaluate the access, experiences and outcomes of older adults receiving psychological therapies in comparison with adults of working age Primary and secondary care providers of psychological therapy services participated in the National Audit of Psychological Therapies. The main standards of access, experience and outcomes were measured by retrospective case records audits of people who completed therapy and a service user questionnaire. Outcomes were measured pre-treatment and post-treatment on the PHQ-9 and GAD-7. A total of 220 services across 97 organisations took part, 137 (62%) in primary care. Service user questionnaires were received from 14 425 (20%) respondents. A total of 122 740 records were audited, of whom 7794 (6.4%) were older adults. They were under represented as 13% of the sample would have been expected to be over 65 years according to age adjusted psychiatric morbidity figures. People over 75 years had the third expected referral rate. Significantly, more older adults than working age adults completed therapy (59.6% vs 48.6%) and were assessed as having 'recovered' post-treatment (58.5% vs 45.5%). Older adults were more satisfied with waiting times and numbers of sessions, but there were no differences in self-reported experience of therapy. Although older adults are less likely to gain access to psychological therapies, they appear to have better outcomes than working age adults. Further work is needed to improve access for older people. Copyright © 2014 John Wiley & Sons, Ltd.

Is There a Paradox of Aging: When the Negative Aging Stereotype Meets the Positivity Effect in Older Adults.

PubMed

Zhou, Liqing; Lu, Jia; Chen, Guopeng; Dong, Li; Yao, Yujia

2017-01-01

Background/Study Context: Socioemotional selectivity theory (SST) states that the positivity effect is a result of older adults' emotion regulation and that older adults derive more emotional satisfaction from prioritizing positive information processing. The authors explored whether the positivity effect appeared when the negative aging stereotype was activated in older adults and also whether the effect differed between mixed and unmixed valence conditions. Sixty younger (18-23 years of age) and 60 older (60-87 years of age) adults were randomly assigned to a control group and a priming group, in which the negative aging stereotype was activated. All the participants were asked to select 15 words that best described the elderly from a mixed-word list (positive and negative words were mixed together) and from an unmixed-word list (positive and negative words were separated). Older adults in the control group selected more positive words, whereas among younger adults, selection did not differ by valence in either the mixed- or unmixed-word list conditions. There were no differences between the positive and negative word choices of the younger and older adults in the priming group. We calculated the differences between the numbers of positive and negative words, and the differences in the older adults' word choices were larger than those among the younger adults; the differences were also larger in the control group than in the priming group. The positivity effect worked by choosing positive stimuli rather than avoiding negative stimuli. The role of emotion regulation in older adults was limited, and when the positivity effect faced the effect of the negative aging stereotype, the negative stereotype effect was dominant. Future research should explore the changes in the positivity effect in the face of a positive aging stereotype and what roles other factors (e.g., activation level of the stereotype, arousal level of affective words) might play.

Cancer treatment decision-making among young adults with lung and colorectal cancer: a comparison with adults in middle age.

PubMed

Mack, Jennifer W; Cronin, Angel; Fasciano, Karen; Block, Susan D; Keating, Nancy L

2016-09-01

Our aim is to understand experiences with treatment decision-making among young adults with cancer. We studied patients with lung cancer or colorectal cancer in the Cancer Care Outcomes Research and Surveillance Consortium, a prospective cohort study. We identified 148 young adult patients aged 21-40 years who completed baseline interview questions about cancer treatment decision-making; each was propensity score matched to three middle adult patients aged 41-60 years, for a cohort of 592 patients. Patients were asked about decision-making preferences, family involvement in decision-making, and worries about treatment. An ordinal logistic regression model evaluated factors associated with more treatment worries. Young and middle-aged adults reported similar decision-making preferences (p = 0.80) and roles relative to physicians (p = 0.36). Although family involvement was similar in the age groups (p = 0.21), young adults were more likely to have dependent children in the home (60% younger versus 28% middle-aged adults, p < 0.001). Young adults reported more worries about time away from family (p = 0.002), and, in unadjusted analyses, more cancer treatment-related worries (mean number of responses of 'somewhat' or 'very' worried 2.5 for younger versus 2.2 for middle-aged adults, p = 0.02.) However, in adjusted analyses, worries were associated with the presence of dependent children in the home (odds ratio [OR] 1.55, 95% CI = 1.07-2.24, p = 0.02), rather than age. Young adults involve doctors and family members in decisions at rates similar to middle-aged adults but experience more worries about time away from family. Patients with dependent children are especially likely to experience worries. Treatment decision-making strategies should be based on individual preferences and needs rather than age alone.

Aging and older adults in three Roman Catholic magazines: Successful aging and the Third and Fourth Ages reframed.

PubMed

Sawchuk, Dana

2015-12-01

This article is a qualitative content analysis of how aging and older adults are represented in the articles of three Roman Catholic magazines in the United States: America, Commonweal, and U.S. Catholic. The findings suggest that, as in mainstream secular magazines, the concept of successful aging is common in portrayals of older adults in the Third Age. Distinctive in Catholic magazine portrayals of successful aging is an emphasis on meaningful activity and on the wisdom that is gained and transmitted in this stage of life. In contrast to the lack of attention to Fourth Age decline in mainstream magazines, in the Catholic publications the difficult features of such deterioration are acknowledged but are also reframed as potential sources of value. The theoretical implications of these more complex faith-based renderings of the Third and Fourth Ages are briefly explored. Copyright © 2015 Elsevier Inc. All rights reserved.

Aging Parents' Daily Support Exchanges With Adult Children Suffering Problems.

PubMed

Huo, Meng; Graham, Jamie L; Kim, Kyungmin; Birditt, Kira S; Fingerman, Karen L

2017-06-17

When adult children incur life problems (e.g., divorce, job loss, health problems), aging parents generally report providing more frequent support and experiencing poorer well-being. Yet, it is unclear how adult children's problems may influence aging parents' daily support exchanges with these children or the parents' daily mood. Aging parents from the Family Exchanges Study Wave 2 (N = 207, Mage = 79.86) reported providing and receiving emotional support, practical support, and advice from each adult child each day for 7 days. Parents also rated daily positive and negative mood. Multilevel models showed that aging parents were more likely to provide emotional and practical support to adult children incurring life problems than children not suffering problems. Parents were also more likely to receive emotional support and advice from these children with problems. Further, parents reported less negative mood on days when providing practical support to children with problems. Examining daily support exchanges adds to our understanding of how children's problems influence parent-child ties in late life. Prior research suggests that children's problems upset parents. In this study, however, it appears that supporting adult children who suffer problems may alleviate aging parents' distress regarding such children. © The Author 2017.

Discounting input from older adults: the role of age salience on partner age effects in the social contagion of memory.

PubMed

Meade, Michelle L; McNabb, Jaimie C; Lindeman, Meghan I H; Smith, Jessi L

2017-05-01

Three experiments examined the impact of partner age on the magnitude of socially suggested false memories. Young participants recalled household scenes in collaboration with an implied young or older adult partner who intentionally recalled false items. In Experiment 1, participants were presented with only the age of their partner (low age-salience context); in Experiment 2, participants were presented with the age of their partner along with a photograph and biographical information about their partner (high age-salience context); in Experiment 3, age salience was varied within the same experiment. Across experiments, participants in both the low age-salience and high age-salience contexts incorporated their partners' misleading suggestions into their own subsequent recall and recognition reports, thus demonstrating social contagion with implied partners. Importantly, the effect of partner age differed across conditions. Participants in the high age-salience context were less likely to incorporate misleading suggestions from older adult partners than from young adult partners, but participants in the low age-salience context were equally likely to incorporate suggestions from young and older adult partners. Participants discount the memory of older adult partners only when age is highly salient.

Age Variation in the Association Between Obesity and Mortality in Adults.

Wang, Zhiqiang; Peng, Yang; Liu, Meina

2017-12-01

The aim of this study was to evaluate the previously reported finding that the association between obesity and mortality strengthens with increasing age. The data were derived from the National Health Interview Survey. Age-specific hazard ratios of mortality for grade 2/3 obesity (BMI ≥ 35 kg/m 2 ), relative to a BMI of 18.5 kg/m 2 to < 25 kg/m 2 , were calculated by using a flexible parametric survival model (240,184 white men) and Cox proportional hazard models (51,697 matched pairs). When the model included interaction terms between obesity and age at the survey, hazard ratios appeared to increase with age if those interaction terms were ignored by fixing age at the survey as a single value. However, when recalculated for adults with various ages at the survey, according to model specifications, hazard ratios were higher for younger adults than for older adults with the same follow-up duration. Based on matched data, hazard ratios were also higher for younger adults (2.14 [95% CI: 1.90-2.40] for those 40-49 years of age) than for older adults (1.22 [95%: 0.91-1.63] for those 90+ years of age). For any given follow-up duration, the association between obesity and mortality weakens with age. The previously reported strengthening of the obesity-mortality association with increasing age was caused by the failure to take all the model specifications into consideration when calculating adjusted hazard ratios. © 2017 The Obesity Society.

Microglial K+ Channel Expression in Young Adult and Aged Mice

PubMed Central

Schilling, Tom; Eder, Claudia

2015-01-01

The K+ channel expression pattern of microglia strongly depends on the cells' microenvironment and has been recognized as a sensitive marker of the cells' functional state. While numerous studies have been performed on microglia in vitro, our knowledge about microglial K+ channels and their regulation in vivo is limited. Here, we have investigated K+ currents of microglia in striatum, neocortex and entorhinal cortex of young adult and aged mice. Although almost all microglial cells exhibited inward rectifier K+ currents upon membrane hyperpolarization, their mean current density was significantly enhanced in aged mice compared with that determined in young adult mice. Some microglial cells additionally exhibited outward rectifier K+ currents in response to depolarizing voltage pulses. In aged mice, microglial outward rectifier K+ current density was significantly larger than in young adult mice due to the increased number of aged microglial cells expressing these channels. Aged dystrophic microglia exhibited outward rectifier K+ currents more frequently than aged ramified microglia. The majority of microglial cells expressed functional BK-type, but not IK- or SK-type, Ca2+-activated K+ channels, while no differences were found in their expression levels between microglia of young adult and aged mice. Neither microglial K+ channel pattern nor K+ channel expression levels differed markedly between the three brain regions investigated. It is concluded that age-related changes in microglial phenotype are accompanied by changes in the expression of microglial voltage-activated, but not Ca2+-activated, K+ channels. PMID:25472417

The Effects of Avatars' Age on Older Adults' Self-Disclosure and Trust.

2018-03-01

Older adults are increasingly interacting with other people online via virtual avatars, yet little is known about how avatars affect older adults' behavior. This study examines how interacting avatars' age affects older adult's self-disclosure and trust in a relation-building context. Previous studies have found that users can take on behaviors consistent with characteristics of the avatars. In social interactions, people also assess their avatar in relation to other avatars for similarity or differences. We conducted a 2 (self-avatar: old vs. young) × 2 (other's avatar: old vs. young) experiment with older-adult participants aged 60+ (n = 95). The findings show that using younger avatars did not increase self-disclosure. However, the older-adult participants disclosed more information when their avatar's age matched their partner avatar's age (i.e., old to old, young to young). They also trust their partners more when the interacting avatars shared similar age. This study provides theoretical insights into the role of avatars in online relationship-building and extends our understanding of the avatar effects on older adults.

Age-Related Locomotion Characteristics in Association with Balance Function in Young, Middle-Aged, and Older Adults.

The purpose of this study was to examine age-related gait characteristics and their associations with balance function in older adults. A total of 51 adult volunteers participated. All subjects underwent locomotion analysis using a 3D motion analysis and 12-channel dynamic electromyography system. Dynamic balance function was assessed by the Berg Balance Scale. Older adults showed a higher level of muscle activation than young adults, and there were significant positive correlations between increased age and activation of the trunk and thigh muscles in the stance and swing phase of the gait cycle. In particular, back extensor muscle activity was mostly correlated with the dynamic balance in older adults. Thus, back extensor muscle activity in walking may provide a clue for higher falling risk in older adults. This study demonstrates that the back extensor muscles play very important roles with potential for rehabilitation training to improve balance and gait in older adults.

Most older adults prefer to age in place, and supporting older adults to remain in their own homes and communities is also favored by policy makers. Technology can play a role in staying independent, active and healthy. However, the use of technology varies considerably among older adults. Previous research indicates that current models of technology acceptance are missing essential predictors specific to community-dwelling older adults. Furthermore, in situ research within the specific context of aging in place is scarce, while this type of research is needed to better understand how and why community-dwelling older adults are using technology. To explore which factors influence the level of use of various types of technology by older adults who are aging in place and to describe these factors in a comprehensive model. A qualitative explorative field study was set up, involving home visits to 53 community-dwelling older adults, aged 68-95, living in the Netherlands. Purposive sampling was used to include participants with different health statuses, living arrangements, and levels of technology experience. During each home visit: (1) background information on the participants' chronic conditions, major life events, frailty, cognitive functioning, subjective health, ownership and use of technology was gathered, and (2) a semistructured interview was conducted regarding reasons for the level of use of technology. The study was designed to include various types of technology that could support activities of daily living, personal health or safety, mobility, communication, physical activity, personal development, and leisure activities. Thematic analysis was employed to analyze interview transcripts. The level of technology use in the context of aging in place is influenced by six major themes: challenges in the domain of independent living; behavioral options; personal thoughts on technology use; influence of the social network; influence of organizations, and the

Median raphe cysts of the perineum are uncommon congenital lesions of the male genitalia. They can be found all the way from the distal penis and scrotum toward the perineum in a midline position. They are considered as congenital alterations in embryologic development. A case of a 6 year-old boy is presented. Review of the literature relevant to children was made regarding the embryologic, diagnostic, and treatment aspects. We believe it is important that adult and pediatric urologists recognize these lesions and their management to provide the appropriate information to the parents.

Age differences in autobiographical memory across the adult lifespan: older adults report stronger phenomenology.

PubMed

Luchetti, Martina; Sutin, Angelina R

2018-01-01

As an individual's life story evolves across adulthood, the subjective experience (phenomenology) of autobiographical memory likely changes. In addition to age at retrieval, both the recency of the memory and the age when a memory is formed may be particularly important to its phenomenology. The present work examines the effect of three temporal factors on phenomenology ratings: (a) age of the participant, (b) age at the event reported in the memory, and (c) memory age (recency). A large sample of Americans (N = 1120), stratified by chronological age, recalled and rated two meaningful memories, a Turning Point and an Early Childhood Memory. Ratings of phenomenology (e.g., vividness of turning points) were higher among older adults compared to younger adults. Memories of events from the reminiscence bump were more positive in valence than events from other time periods but did not differ on other phenomenological dimensions; recent memories had stronger phenomenology than remote memories. In contrast to phenomenology, narrative content was generally unrelated to participant age, age at the event, or memory age. Overall, the findings indicate age-related differences in how meaningful memories are re-experienced.

Age-specific MRI brain and head templates for healthy adults from 20 through 89 years of age

2015-01-01

This study created and tested a database of adult, age-specific MRI brain and head templates. The participants included healthy adults from 20 through 89 years of age. The templates were done in five-year, 10-year, and multi-year intervals from 20 through 89 years, and consist of average T1W for the head and brain, and segmenting priors for gray matter (GM), white matter (WM), and cerebrospinal fluid (CSF). It was found that age-appropriate templates provided less biased tissue classification estimates than age-inappropriate reference data and reference data based on young adult templates. This database is available for use by other investigators and clinicians for their MRI studies, as well as other types of neuroimaging and electrophysiological research.1 PMID:25904864

Effects of age and lean direction on the threshold of single-step balance recovery in younger, middle-aged and older adults.

PubMed

Carbonneau, Evelyne; Smeesters, Cécile

2014-01-01

Several studies have quantified and compared balance recovery between healthy younger and older adults, using a variety of large postural perturbations and loss of balance directions. However, to the best of our knowledge, no studies at the threshold of balance recovery, where avoiding a fall is not always possible, have included middle-aged adults. We thus determined the maximum lean angle from which 20 younger, 16 middle-aged and 16 older healthy adults could be suddenly released and still recover balance using a single step for forward, sideways and backward leans. Results showed that the maximum lean angles of younger adults were 23% greater than middle-aged adults and 48% greater than older adults. The maximum lean angles for forward leans were 23% greater than sideways leans and 22% greater than backward leans. These declines with age and lean direction were associated with declines in response initiation, execution and geometry. Finally exponential regressions showed that the critical ages at which the ability to recover balance and avoid a fall significantly decreases were 51.0, 60.6 and 69.9 yrs for forward, sideways and backward leans, respectively. Therefore, we have demonstrated that age affects the ability to recover balance nearly a decade earlier than the rate of falls. Future studies should thus not only include older adults over 65 yrs, but also middle-aged adults under 65 yrs, or recruit all ages from 18 to 85 yrs. Finally, the critical ages identified in this study may justify an earlier screening of aging adults to prevent future falls, especially the first fall. Copyright © 2013 Elsevier B.V.

To investigate the effects of marijuana in the development of incident cardiovascular and cerebrovascular outcomes. Participants were 5113 adults aged 18 to 30 years at baseline (1985-1986) from the Coronary Artery Risk Development in Young Adults study, who were followed for more than 25 years. We estimated cumulative lifetime exposure to marijuana using repeated assessments collected at examinations every 2 to 5 years. The primary outcome was incident cardiovascular disease (CVD) through 2013. A total of 84% (n = 4286) reported a history of marijuana use. During a median 26.9 years (131 990 person-years), we identified 215 CVD events, including 62 strokes or transient ischemic attacks, 104 cases of coronary heart disease, and 50 CVD deaths. Compared with no marijuana use, cumulative lifetime and recent marijuana use showed no association with incident CVD, stroke or transient ischemic attacks, coronary heart disease, or CVD mortality. Marijuana use was not associated with CVD when stratified by age, gender, race, or family history of CVD. Neither cumulative lifetime nor recent use of marijuana is associated with the incidence of CVD in middle age.

Aging is not only a population phenomenon but also an experience and an individual reality. Vital Aging ® is a program that considers active aging as the lifelong adaptation process of maximizing health and independence, physical and cognitive functioning, positive affect regulation and control, and social engagement. Through its different versions and editions, it has demonstrated being an effective program to promote active aging. The aim of this study is to determine the effectiveness of the "face-to-face" and "combined" versions of the program to promote active aging in Mexican older adults trial. Seventy-six older adults aged 60 years and over participated in a quasi-experimental study and were recruited in a senior center to participate in the two experimental conditions: Vital Aging face-to-face (VA-FF) (n=35) and Vital Aging combined (VA-C; multimedia/face-to-face) (n=15), and the remaining 26 adults were assigned to a control group. Pretest and posttest assessments were performed after the theoretical-practical intervention. Mean differences and size effects were calculated for estimating the effect of the program. At the end of the study, participants showed improvements in the active aging outcome measures. Positive effects were observed in the frequency of intellectual, cultural - artistic, and social activities, perceptions of aging, satisfaction with social relationships, and self-efficacy for aging. Additionally, those who participated in VA-FF showed better memory performance, meta-memory, and a trend to report less memory problems, while older persons in VA-C showed a trend to have better life satisfaction. No effects were observed in physical activity, frequency of social relationships, and subjective health.

Introduction Aging is not only a population phenomenon but also an experience and an individual reality. Vital Aging® is a program that considers active aging as the lifelong adaptation process of maximizing health and independence, physical and cognitive functioning, positive affect regulation and control, and social engagement. Through its different versions and editions, it has demonstrated being an effective program to promote active aging. The aim of this study is to determine the effectiveness of the “face-to-face” and “combined” versions of the program to promote active aging in Mexican older adults trial. Methods Seventy-six older adults aged 60 years and over participated in a quasi-experimental study and were recruited in a senior center to participate in the two experimental conditions: Vital Aging face-to-face (VA-FF) (n=35) and Vital Aging combined (VA-C; multimedia/face-to-face) (n=15), and the remaining 26 adults were assigned to a control group. Pretest and posttest assessments were performed after the theoretical–practical intervention. Mean differences and size effects were calculated for estimating the effect of the program. Results At the end of the study, participants showed improvements in the active aging outcome measures. Positive effects were observed in the frequency of intellectual, cultural – artistic, and social activities, perceptions of aging, satisfaction with social relationships, and self-efficacy for aging. Additionally, those who participated in VA-FF showed better memory performance, meta-memory, and a trend to report less memory problems, while older persons in VA-C showed a trend to have better life satisfaction. No effects were observed in physical activity, frequency of social relationships, and subjective health. Conclusion Findings show that the Vital Aging program in face-to-face and combined versions encourages active aging in Mexican older persons. These results are in general similar to those found in

Grip force control is a crucial function for human to guarantee the quality of life. To examine the effects of age on grip force control, 10 young adults and 11 late middle-aged adults participated in visually guided tracking tasks using different target force levels (25, 50, and 75% of the subject's maximal grip force). Multiple measures were used to evaluate the tracking performance during force rising phase and force maintenance phase. The measurements include the rise time, fuzzy entropy, mean force percentage, coefficient of variation, and target deviation ratio. The results show that the maximal grip force was significantly lower in the late middle-aged adults than in the young adults. The time of rising phase was systematically longer among late middle-aged adults. The fuzzy entropy is a useful indicator for quantitating the force variability of the grip force signal at higher force levels. These results suggest that the late middle-aged adults applied a compensatory strategy that allow allows for sufficient time to reach the required grip force and reduce the impact of the early and subtle degenerative changes in hand motor function.

Limited data are available concerning the extent to which the initial prostate-specific antigen (PSA) measurement in men younger than age 60 predicts for the risk of prostate cancer (CaP) and how this compares to other known risk factors. From 1991 to 2001, 13,943 men younger than 60 years old participated in a CaP screening study. Men aged 40 to 49 years were eligible for the study if they had a positive family history or African-American heritage, and men older than 50 years were screened without respect to risk factors. The CaP detection rate, PSA velocity, pathologic features, and treatment outcomes were evaluated as a function of the baseline PSA level. The median PSA level was 0.7 ng/mL for men aged 40 to 49 years and 0.9 ng/mL for men aged 50 to 59. A baseline PSA level between the median and 2.5 ng/mL was associated with a 14.6-fold and 7.6-fold increased risk of CaP in men aged 40 to 49 and 50 to 59 years, respectively. A greater baseline PSA value was also associated with a significantly greater PSA velocity, more aggressive tumor features, a greater biochemical progression rate, and a trend toward a greater cancer-specific mortality rate. In men younger than 60, a baseline PSA value between the age-specific median and 2.5 ng/mL was a significant predictor of later CaP and was associated with a significantly greater PSA velocity. A young man's baseline PSA value was a stronger predictor of CaP than family history, race, or suspicious digital rectal examination findings. A greater baseline PSA level was associated with significantly more adverse pathologic features and biochemical progression.

Key goals and indicators for successful aging of adults with early-onset disability.

PubMed

LaPlante, Mitchell P

2014-01-01

Substantial improvements have occurred in the longevity of several groups of individuals with early-onset disabilities, with many now surviving to advanced ages. This paper estimates the population of adults aging with early-onset disabilities at 12-15 million persons. Key goals for the successful aging of adults with early-onset disabilities are discussed, emphasizing reduction in risks for aging-related chronic disease and secondary conditions, while promoting social participation and independence. However, indicators suggest that elevated risk factors for aging-related chronic diseases, including smoking, obesity, and inactivity, as well as barriers to prevention and the diminished social and economic situation of adults with disabilities are continuing impediments to successful aging that must be addressed. Increased provider awareness that people with early-onset disabilities are aging and can age successfully and the integration of disability and aging services systems are transformative steps that will help adults with early-onset disability to age more successfully.

Self-transcendence and depression in middle-age adults.

PubMed

Ellermann, C R; Reed, P G

2001-11-01

Self-transcendence has been found to be an important correlate of mental health in older adults and adults facing the end of life. This study extends current theory by examining the relationship of transcendence and other transcendence variables to depression in middle-age adults (N = 133). Reed's Self-Transcendence Scale, the Center for Epidemiological Studies-Depression Scale, and measures of parenting, acceptance and spirituality were administered. Findings indicating significant inverse correlations between self-transcendence and depression, as well as between other measures of transcendence and depression support Reed's (1991b) theory. Multiple regression analysis indicated that acceptance may be another significant correlate of depression. Significant gender differences and age-related patterns of increased levels of self-transcendence were found. Study results illuminate the need to continue research into developmentally based transcendence variables related to various experiences of health and well-being across the life span.

Injury patterns may differ in trauma patients when age is considered. This information is relevant in the management of trauma patients and for planning preventive measures. We included in the study all patients admitted for traumatic disease in the participating ICUs from November 23 rd , 2012 to July 31 st , 2015 with complete records. Data on epidemiology, injury patterns, severity scores, acute management, resources utilisation and outcome were recorded and compared in the following groups of age: ≤55years (young adults), 56-65 years (adults), 66-75 years (elderly), >75years (very elderly). Quantitative data were reported as median (Interquartile Range (IQR) 25-75) and categorical data as number and percentage. Comparison between groups of age with quantitative variables was performed using the analysis of variance (ANOVA) test. Differences between groups with categorical variables were compared using the chi-square test. A value of p<0.05 was considered significant. We included 2700 patients (78.9% male). Median age was 46 (31-62) years. Blunt trauma was present in 93.7% of the patients. Median RTS was 7.55 (5.97-7.84). Median ISS was 20 (13-26). High-energy trauma secondary to motor-vehicle accident with rhabdomyolysis and drugs abuse showed an inverse linear association with ageing, whilst pedestrian falls with isolated brain injury, being run-over and pre-injury antiplatelets or anticoagulant treatment increased with age (in all cases p<0.001). Multiple injuries were more common in young adults (p<0.001). Acute kidney injury prevalence was higher in elderly and very elderly patients (p<0.001). ICU Mortality increased with age in spite of similar severity scores in all groups (p<0.001). The main cause of death in all groups was intracranial hypertension. Different injury patterns exist in relation with ageing in trauma ICU patients. Adult patients were more likely to present high-energy trauma with significant injuries in different areas whilst elderly

Previous studies that examined age differences in hypermnesia reported inconsistent results. The present experiment investigated whether the different study materials in these studies were responsible for the inconsistency. In particular, the present experiment examined whether the use of a video, as opposed to words and pictures, would eliminate previously reported age differences in hypermnesia. Fifteen college students and 15 older adults viewed a 3-minute video clip followed by two free-recall tests. The results indicated that older adults, as a whole, did not show hypermnesia. However, when older adults were divided into low and high memory groups based on test 1 performance, the high memory group showed hypermnesia whereas the low memory group did not show hypermnesia. The older adults in the low memory group were significantly older than the older adults in the high memory group - indicating that hypermnesia is inversely related to age in older adults. Reminiscence did not show an age-related difference in either the low or high memory group whereas inter-test forgetting did show an age difference in the low memory group. As expected, older adults showed greater inter-test forgetting than young adults in the low memory group. Findings from the present experiment suggest that video produces a pattern of results that is similar to the patterns obtained when words and pictures are used as study material. Thus, it appears that the nature of study material is not the source of inconsistency across the previous studies.

Socially isolated aging adults are at risk of poor health and well-being. Occupational therapy can help address this issue; however, information is needed to guide such work. National surveys characterize social isolation in populations of aging adults but fail to provide meaningful information at a community level. The objective of this study is to describe multiple dimensions of social isolation and related factors among aging adults in diverse urban neighborhoods. Community-based participatory research involving a door-to-door survey of adults 50 years and older was used. Participants ( N = 161) reported social isolation in terms of small social networks (24%) and wanting more social engagement (43%). Participants aged 50 to 64 years reported the highest levels of isolation in most dimensions. Low income, poor health, lack of transportation, and infrequent information access appeared linked to social isolation. Occupational therapists can address social isolation in similar urban communities through policy and practice that facilitate social engagement and network building.

Age is associated with reductions in surface area and cortical thickness, particularly in prefrontal regions. There is also evidence of greater thickness in some regions at older ages. Non-linear age effects in some studies suggest that age may continue to impact brain structure in later decades of life, but relatively few studies have examined the impact of age on brain structure within middle-aged to older adults. We investigated age differences in prefrontal surface area and cortical thickness in healthy adults between the ages of 51 and 81 years. Participants received a structural 3-Tesla magnetic resonance imaging scan. Based on a priori hypotheses, primary analyses focused on surface area and cortical thickness in the dorsolateral prefrontal cortex, anterior cingulate cortex, and orbitofrontal cortex. We also performed exploratory vertex-wise analyses of surface area and cortical thickness across the entire cortex. We found that older age was associated with smaller surface area in the dorsolateral prefrontal and orbitofrontal cortices but greater cortical thickness in the dorsolateral prefrontal and anterior cingulate cortices. Vertex-wise analyses revealed smaller surface area in primarily frontal regions at older ages, but no age effects were found for cortical thickness. Results suggest age is associated with reduced surface area but greater cortical thickness in prefrontal regions during later decades of life, and highlight the differential effects age has on regional surface area and cortical thickness.

This study investigates the relationship between discrimination and mental health in aging transgender adults. Survey responses from 61 transgender adults above 50 ( M age = 57.7, SD = 5.8; 77.1% male-to-female; 78.7% White non-Hispanic) were analyzed. Multivariable logistic regression models examined the relationship between gender- and age-related discrimination, number of everyday discrimination experiences, and past-week depressive distress, adjusting for social support, sociodemographics, and other forms of discrimination. The most commonly attributed reasons for experiencing discrimination were related to gender (80.3%) and age (34.4%). More than half of participants (55.5%) met criteria for past-week depressive distress. In an adjusted multivariable model, gender-related discrimination and a greater number of everyday discrimination experiences were associated with increased odds of past-week depressive distress. Additional research is needed to understand the effects of aging and gender identity on depressive symptoms and develop interventions to safeguard the mental health of this vulnerable aging population.

Data on health care costs for working-age adults with physical disabilities are sparse and the dynamic nature of disability is not captured. To assess the effect of 3 types of disability status (persistent disability, temporary disability, and no disability) on health care expenditures, out-of-pocket (OOP) spending, and financial burden. Data from Medical Expenditure Panel Survey panel 12 (2007-2008) were used. Respondents were classified into 3 groups. Medians of average annual expenditures, OOP expenditures, and financial ratios were weighted. The package R was used for quantile regression analyses. Fifteen percent of the working-age population reported persistent disabilities and 7% had temporary disabilities. The persistent disability group had the greatest unadjusted annual medians for total expenditures ($4234), OOP expenses ($591), and financial burden ratios (1.59), followed by the temporary disability group ($1612, $388, 0.71 respectively). The persistent disability group paid approximately 15% of total health care expenditures out-of-pocket, while the temporary disability group and the no disability group each paid 22% out-of-pocket. After adjusting for other factors, quantile regression shows that the persistent disability group had significantly higher total expenditures, OOP expenses, and financial burden ratios (coefficients 1664, 156, 0.58 respectively) relative to the no disability group at the 50th percentile. Results for the temporary disability group show a similar trend except for OOP expenses. People who have disabling conditions for a longer period have better financial protection against OOP health care expenses but face greater financial burdens because of their higher out-of-pocket expenditures and their socioeconomic disadvantages.

2015-06-01

The purpose of this summary is to examine changes in listening comprehension across the adult lifespan and to identify factors associated with individual differences in listening comprehension. In this article, the author reports on both cross-sectional and longitudinal changes in listening comprehension. Despite significant declines in both sensory and cognitive abilities, listening comprehension remains relatively unchanged in middle-aged listeners (between the ages of 40 and 60 years) compared with young listeners. These results are discussed with respect to possible compensatory factors that maintain listening comprehension despite impaired hearing and reduced cognitive capacities.

The standardization of treatment of older adults with Philadelphia chromosome negative (Ph-) acute lymphoblastic leukemia (ALL) is challenging, especially in the age range of 55-65 years. This study aimed to compare intensive, pediatric-inspired therapy with non-intensive therapy in this population of patients. The outcomes of 67 patients prospectively included in two consecutive pediatric-inspired intensive protocols (ALL-HR03 and ALL-HR11) from the Spanish PETHEMA Group were compared with those from 44 patients included in a contemporary semi-intensive protocol (ALL-OLD07). Baseline patient and ALL characteristics were similar in both groups, except for a younger median age in the intensive group (medians: 58 vs. 62 years). Patients treated intensively had a higher complete remission rate (85% vs. 64%, p = 0.005), a lower cumulative incidence of relapse (39% [95%CI, 25% to 52%] vs. 60% [95%CI, 38% to 77%], p = .003), a similar cumulative incidence of treatment-related mortality (28% [95% CI, 18%, 40%] vs. 21% [95% CI, 10%, 34%]) and superior event-free survival at 2 years (37% [95%CI, 25%-49%) vs. 21% [8%-34%], p = 0.002). On multivariable analysis the type of protocol was the only variable with independent significance for event-free survival (HR [95% CI]: 2 [1.3, 3], p = .002). Compared with less intensive chemotherapy, pediatric-inspired intensive chemotherapy significantly improves the outcome of older adults with Ph-negative ALL in the age range of 55-65 years.

Obesity has been demonstrated to be associated with elevated leukocytes in adults and children. This study assessed the associations between peripheral total and differential leukocyte counts and obesity-related complications in young adults. 12 obese (median age 21.5 (range 19-28) years, median BMI 35.7 (range 32.0-44.9) kg/m(2)) and 11 normal (median age 23 (range 18-27) years, median BMI 19.5 (range 18.1-21.7) kg/m(2)) adults were enrolled. Complete blood count and serum levels of liver enzymes, fasting blood glucose, insulin and lipids were measured, and the homeostasis model assessment of insulin resistance was calculated. Fat mass was calculated using a bioimpedance analysis device, and ultrasonography was performed to measure fat thickness and to detect fatty change of the liver. Total leukocyte and monocyte counts were significantly increased in obese young adults. Total leukocyte count was associated with liver enzyme levels, insulin resistance as well as visceral and subcutaneous fat thickness. Neutrophil count was associated with insulin resistance. Lymphocyte count was associated with serum liver enzymes, insulin resistance, and dyslipidemia. Monocyte count was associated with serum liver enzyme, insulin resistance, visceral and subcutaneous fat thickness, body fat mass, and percentage body fat. The results of this study suggest that chronic low-grade systemic inflammation is associated with obesity-related complications such as nonalcoholic fatty liver disease, insulin resistance, and dyslipidemia in young adults. © 2015 S.

Self-reported Hearing Trouble in Adults Aged 18 and Over: United States, 2014.

2015-09-01

Age is typically the most significant determinant of hearing loss (5,6). Among U.S. adults in 2014, self-reported hearing loss was most prevalent among adults aged 70 and over (43.2%), compared with adults aged 40-69 (19.0%) and aged 18-39 (5.5%). Age-related hearing loss is often overlooked due to its deceptively slow progression, lack of attention from providers, and public acceptance as a condition that is perceived to be a "normal" consequence of aging (7). Among U.S. adults aged 70 and over who had any trouble hearing, 56.8% had seen a doctor or other health care professional about their hearing or ear problems in the past 5 years, but only 42.0% had ever used a hearing aid. Younger adults (aged 18-39) who had any trouble hearing were even less likely to have seen a doctor or used a hearing aid, but they were more likely to have used other assistive technology because of their hearing compared with adults aged 40-69 or 70 and over. Among U.S. adults who had any trouble hearing without a hearing aid, 1.7% were deaf, but the majority (62.6%) had mild hearing loss (defined as "a little trouble hearing"). Men were more likely than women to have self-reported trouble hearing, a sex disparity that has been documented globally among all age groups (8). Men were also more likely than women to state they had moderate trouble hearing.

We conducted a survey to document World Wide Web use patterns in middle-aged (ages 40-59), young-old (ages 60-74), and old-old adults (ages 75-92). We conducted this survey of 550 adults 40 years old and over in southeastern Michigan, and the overall response rate was approximately 71%. The results suggested that (a) there are distinct age and demographic differences in individuals who use the Web; (b) middle-aged and older Web users are similar in their use patterns; (c) the two primary predictors for not using the Web are lack of access to a computer and lack of knowledge about the Web; (d) old-old adults have the least interest in using the Web compared with middle-aged and young-old adults; and (e) the primary content areas in learning how to use the Web are learning how to use electronic mail and accessing health information and information about traveling for pleasure. This research may serve as a preliminary attempt to ascertain the issues that must be faced in order to increase use of the World Wide Web in middle-aged and older adults.

The Medicare Part D Prescription Drug Program places an unprecedented degree of choice in the hands of older adults despite concerns over their ability to make effective decisions and desire to have extensive choice in this context. While previous research has compared older adults to younger adults along these dimensions, our study, in contrast, examines how likelihood to delay decision making and preferences for choice differ by age among older age cohorts. Our analysis is based on responses of older adults to a simulation of enrollment in Medicare Part D. We examine how age, numeracy, cognitive reflection, and the interaction between age and performance on these instruments are related to the decision to enroll in a Medicare prescription drug plan and preference for choice in this context. We find that numeracy and cognitive reflection are positively associated with enrollment likelihood and that they are more important determinants of enrollment than age. We also find that greater numeracy is associated with a lower willingness to pay for choice. Hence, our findings raise concern that older adults, and, in particular, those with poorer numerical processing skills, may need extra support in enrolling in the program: they are less likely to enroll than those with stronger numerical processing skills, even though they show greater willingness to pay for choice.

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

PubMed Central

Brown, Louise A.

2016-01-01

Working memory is vulnerable to age-related decline, but there is debate regarding the age-sensitivity of different forms of spatial-sequential working memory task, depending on their passive or active nature. The functional architecture of spatial working memory was therefore explored in younger (18–40 years) and older (64–85 years) adults, using passive and active recall tasks. Spatial working memory was assessed using a modified version of the Spatial Span subtest of the Wechsler Memory Scale – Third Edition (WMS-III; Wechsler, 1998). Across both age groups, the effects of interference (control, visual, or spatial), and recall type (forward and backward), were investigated. There was a clear effect of age group, with younger adults demonstrating a larger spatial working memory capacity than the older adults overall. There was also a specific effect of interference, with the spatial interference task (spatial tapping) reliably reducing performance relative to both the control and visual interference (dynamic visual noise) conditions in both age groups and both recall types. This suggests that younger and older adults have similar dependence upon active spatial rehearsal, and that both forward and backward recall require this processing capacity. Linear regression analyses were then carried out within each age group, to assess the predictors of performance in each recall format (forward and backward). Specifically the backward recall task was significantly predicted by age, within both the younger and older adult groups. This finding supports previous literature showing lifespan linear declines in spatial-sequential working memory, and in working memory tasks from other domains, but contrasts with previous evidence that backward spatial span is no more sensitive to aging than forward span. The study suggests that backward spatial span is indeed more processing-intensive than forward span, even when both tasks include a retention period, and that age predicts

Adult age differences in the perceptual span during reading.

Risse, Sarah; Kliegl, Reinhold

2011-06-01

Following up on research suggesting an age-related reduction in the rightward extent of the perceptual span during reading (Rayner, Castelhano, & Yang, 2009), we compared old and young adults in an N + 2-boundary paradigm in which a nonword preview of word N + 2 or word N + 2 itself is replaced by the target word once the eyes cross an invisible boundary located after word N. The intermediate word N + 1 was always three letters long. Gaze durations on word N + 2 were significantly shorter for identical than nonword N + 2 preview both for young and for old adults, with no significant difference in this preview benefit. Young adults, however, did modulate their gaze duration on word N more strongly than old adults in response to the difficulty of the parafoveal word N + 1. Taken together, the results suggest a dissociation of preview benefit and parafoveal-on-foveal effect. Results are discussed in terms of age-related decline in resilience towards distributed processing while simultaneously preserving the ability to integrate parafoveal information into foveal processing. As such, the present results relate to proposals of regulatory compensation strategies older adults use to secure an overall reading speed very similar to that of young adults.

This study examined the effects of age and gender on wideband energy absorbance in adults with normal middle ear function. Forty young adults (14 men, 26 women, aged 20-38 years), 31 middle-aged adults (16 men, 15 women, aged 42-64 years), and 30 older adults (20 men, 10 women, aged 65-82 years) were assessed. Energy absorbance (EA) data were collected at 30 frequencies using a prototype commercial instrument developed by Interacoustics. Results showed that the young adult group had significantly lower EA (between 400 and 560 Hz) than the middle-aged group. However, the middle-aged group showed significantly lower EA (between 2240 and 5040 Hz) than the young adult group. In addition, the older adult group had significantly lower EA than the young adult group (between 2520 and 5040 Hz). No significant difference in EA was found at any frequency between middle-aged and older adults. Across age groups, gender differences were found with men having significantly higher EA values than women at lower frequencies, whereas women had significantly higher EA at higher frequencies. This study provides evidence of the influence of gender and age on EA in adults with normal outer and middle ear function. These findings support the importance of establishing age- and gender-specific EA norms for the adult population.

Older adults represent the fastest-growing age demographic of the population. Physiological changes associated with primary aging and concurrent chronic disease adversely impact functional capacity, health outcomes, and quality of life. For these reasons, there is a national emphasis for healthcare providers to improve the health, function, and quality of life of older adults to preserve independent living and psychological well-being. The benefits of regular physical activity or exercise with regard to aging and disease are indisputable, yet many clinicians do not prescribe exercise to older adults. This reluctance may be attributable to a lack of knowledge regarding appropriate exercise prescription for older adults in light of the potential risks and benefits of various doses and types of exercise. In addition, clinicians and patients may have concerns about potential health considerations relevant to older adults such as comprehensive pre-exercise screening and exercise-drug interactions. In light of this, the following review presents (1) guidelines for exercise prescription in older adults and modification of these guidelines for patients with the most common age-associated comorbidities; (2) recommendations for pre-exercise screening prior to initiating an exercise program in older adults; (3) considerations for older adults on one or more medications; and (4) common barriers to adopting and maintaining exercise in an older population. Our goal is to provide a framework that clinicians can follow when prescribing exercise in older adults while considering the unique characteristics and concerns present in this population.

Background Individuals with cerebral palsy have less lean body mass, greater relative adiposity, and lower fitness and physical activity participation; and yet, the prevalence of age-related multimorbidity in this population has yet to be established. Purpose To examine the prevalence of lifestyle-related chronic conditions and multimorbidity in a sample of middle-aged adults with cerebral palsy. Methods A clinic-based sample of middle-aged adults with cerebral palsy was examined using Electronic Medical Records Search Engine (EMERSE) software. Our cohort included n= 435 individuals aged 40–60 years old, with an ICD-9/10-CM Diagnosis Code for cerebral palsy. Prevalence of 12 chronic conditions were evaluated, including existing diagnoses or historical record of: osteopenia/osteoporosis, myocardial infarction, stroke, coronary artery disease, impaired glucose tolerance/type 2 diabetes, other cardiovascular conditions, rheumatoid arthritis, osteoarthritis, asthma, emphysema, pre-hypertension/hypertension, and hyperlipidemia. Multivariate logistic models were used to estimate adjusted mulitmorbidity (i.e., ≥2 chronic conditions), adjusting for age, sex, smoking status, obesity, and Gross Motor Function Classification System (GMFCS). Results There were 137 unique multimorbidity combinations. Multimorbidity was significantly more prevalent among obese versus non-obese individuals for both GMFCS I–III (75.8% vs. 53.6%) and GMFCS IV–V (79.0% vs 64.2%), but was also significantly higher in non-obese individuals with GMFCS IV–V (64.2%) compared to individuals with non-obese individuals with GMFCS I–III (53.6%). Both obesity status (OR: 2.20; 95% CI 1.32–2.79) and the GMFCS IV–V category (OR: 1.81; 95% CI 1.32–3.68) were independently associated with multimorbidity. Conclusion Middle-aged adults with cerebral palsy have high estimates of multimorbidity, and both obesity and higher GMFCS levels are independently associated with greater risk. PMID:28065772

This study investigates the relationship between discrimination and mental health in aging transgender adults. Survey responses from 61 transgender adults above 50 (Mage = 57.7, SD = 5.8; 77.1% male-to-female; 78.7% White non-Hispanic) were analyzed. Multivariable logistic regression models examined the relationship between gender- and age-related discrimination, number of everyday discrimination experiences, and past-week depressive distress, adjusting for social support, sociodemographics, and other forms of discrimination. The most commonly attributed reasons for experiencing discrimination were related to gender (80.3%) and age (34.4%). More than half of participants (55.5%) met criteria for past-week depressive distress. In an adjusted multivariable model, gender-related discrimination and a greater number of everyday discrimination experiences were associated with increased odds of past-week depressive distress. Additional research is needed to understand the effects of aging and gender identity on depressive symptoms and develop interventions to safeguard the mental health of this vulnerable aging population.

One of the important determinants of well-being among aging parents is their relationship with adult children. Using the two waves of the Korean Longitudinal Study of Ageing, this study examined how different types of ties with adult children affect the life satisfaction of the Korean middle-aged, the young-old, and the oldest-old adults. Multigroup analysis was used to see if the effects of ties with adult children differ by the three age-groups. The results showed that frequency of contact had positive effect on life satisfaction for all of the age-groups. However, coresidence with children had a negative effect for the middle-aged, but a positive effect for the oldest-old. Finally, exchanges of support with adult children had significant effects only for the young-old. These results show that the importance of different types of ties with children change according to aging parents' life stages.

Objective Past research has investigated age differences in frontal-based decision making, but few studies have focused on the behavioral effects of striatal-based changes in healthy aging. Feedback learning has been found to vary with dopamine levels; increases in dopamine facilitate learning from positive feedback, whereas decreases facilitate learning from negative feedback. Given previous evidence of striatal dopamine depletion in healthy aging, we investigated behavioral differences between college-aged and healthy old adults using a feedback learning task that is sensitive to both frontal and striatal processes. Method Seventeen college-aged (M = 18.9 years) and 24 healthy, older adults (M = 70.3 years) completed the Probabilistic selection task, in which participants are trained on probabilistic stimulus-outcome information and then tested to determine whether they learned more from positive or negative feedback. Results As a group, the old adults learned equally well from positive and negative feedback, whereas the college-aged group learned more from positive than negative feedback, F(1, 39) = 4.10, p < .05, reffect = .3. However, these group differences were not due to the older individuals being more balanced learners. Most individuals of both ages were balanced learners, but while all of the remaining young learners had a positive bias, the remaining older learners were split between those with positive and negative learning biases (χ2(2) = 6.12, p<.047). Conclusions These behavioral results are consistent with the dopamine theory of striatal aging, and suggest there might be adult age differences in the kinds of information people use when faced with a current choice.

To assess the association between rural and urban residential mobility and cognitive function among middle-aged and older adults in China. We used data from the World Health Organization Study on global AGEing and adult health that included adults age 50+ from China ( N = 12,410). We used multivariate linear regressions to examine how residential mobility and age at migration were associated with cognitive function. Urban and urban-to-urban residents had the highest level of cognitive function, whereas rural and rural-to-rural residents had the poorest cognitive function. Persons who migrated to/within rural areas before age 20 had poorer cognitive function than those who migrated during later adulthood. Socioeconomic factors played a major role in accounting for the disparities in cognition; however, the association remained significant after inclusion of all covariates. Residential mobility and age at migration have significant implications for cognitive function among middle-aged and older adults in China.

Worldwide, the incidence of cancer in young adults (20-39 years) is increasing, and represents an important cause of mortality in this age group. A retrospective study was undertaken to provide information that may lead to improved treatment outcomes. Epidemiological, clinicopathological, treatment, and survival information were retrieved from the electronic database registry of a tertiary referral hospital in São Paulo, Brazil for patients 19-29 years of age diagnosed with cancer between January 2007 and December 2012. There were 960 patients with a median age at diagnosis of 26 years; female patients comprised 59.2%. A previous diagnosis of malignancy was present in 2.3%; 0.4% had malignant tumors that were radiation-associated; regular alcohol use was present in 10.4%; 9% of patients reported tobacco use; a family history of cancer was present in 41.7%. Malignant tumors included carcinomas (45.7%), germ cell and trophoblastic neoplasms (12.3%), and lymphomas (12.1%). Median follow-up was 47.7 months (range: 0.62-100.9 months) during which time 111 patients (13.5%) died. Carcinomas (n = 43, 38.7%), soft tissue sarcomas (n = 18, 16.2%), and leukemias (n = 10, 9.0%) were the most common causes of death. This study has shown that carcinomas represent the most common malignancy in adolescents and young adults referred to a tertiary cancer center in Brazil and are the most common cause of mortality. Because clinical outcome may be affected by multiple factors in this patient population, further global studies are needed to characterize this population and improve clinical care.

Impact of age-relevant goals on future thinking in younger and older adults.

Lapp, Leann K; Spaniol, Julia

This study investigated how personal goals influence age differences in episodic future thinking. Research suggests that personal goals change with age and like autobiographical memory, future thinking is thought to be organised and impacted by personal goals. It was hypothesised that cueing older adults with age-relevant goals should modulate age differences in episodic details and may also influence phenomenological characteristics of imagined scenarios. Healthy younger and older adults completed the Future Thinking Interview [Addis, D. R., Wong, A. T., & Schacter, D. L. (2008). Age-related changes in the episodic simulation of future events. Psychological Science, 19(1), 33-41. doi: 10.1111/j.1467-9280.2008.02043.x ] adapted to activate age-appropriate goals. Narratives were scored with an established protocol to obtain objective measures of episodic and semantic details. Subjective features such as emotionality and personal significance showed age differences as a function of goal domain while other features (e.g., vividness) were unaffected. However, consistent with prior reports, older adults produced fewer episodic details than younger adults and this was not modulated by goal domain. The results do not indicate that goal activation affects level of episodic detail. With respect to phenomenological aspects of future thinking, however, younger adults show more sensitivity to goal activation, compared with older adults.

Aging and the HPA axis: Stress and resilience in older adults

Gaffey, Allison E.; Bergeman, C.S.; Clark, Lee Anna; Wirth, Michelle M.

2017-01-01

Hypothalamic-pituitary-adrenal (HPA) axis function may change over the course of aging, and altered diurnal or stress-induced secretion of the hormone cortisol could predispose older adults to negative health outcomes. We propose that psychological resilience may interact with diurnal cortisol to affect health outcomes later in life. Emotion regulation and social support are two constructs that contribute to resilience and exhibit age-specific patterns in older adults. Determining how the use of resilience resources interacts with age-related diurnal cortisol will improve our understanding of the pathways between stress, resilience, and well-being. In this review, we assess published studies evaluating diurnal cortisol in older adults to better understand differences in their HPA axis functioning. Evidence thus far suggests that diurnal cortisol may increase with age, although cross-sectional studies limit the conclusions that can be drawn. We also review extant evidence connecting age-specific signatures of emotion regulation and social support with diurnal cortisol. Conclusions are used to propose a preliminary model demonstrating how resilience resources may modulate the effects of cortisol on health in aging. PMID:27377692

Epidemiological studies on myasthenia gravis (MG) in Mexico is mainly derived from experiences in referral centers. To describe the epidemiological characteristics of hospital discharges during 2010 with the diagnosis of MG in adults hospitalized in the Mexican public health system. We consulted the database of hospital discharges during 2010 of the National Health Information System (Ministry of Health, IMSS, IMSS oportunidades, ISSSTE, PEMEX, and the Ministry of Defense). The MG records were identified by the code G70.0 of the International Classification of Diseases 10th revision. During 2010 there were 5,314,132 hospital discharges (4,254,312 adults). Among them, 587 (0.01%) were adults with MG (median age: 47 years, 60% women). Women with MG were significantly younger than men (median age: 37 vs. 54 years, respectively; p < 0.001). The median hospital stay was six days. The case fatality rate was 3.4%, without gender differences. Age was associated with the probability of death. We confirmed the bimodal age-gender distribution in MG. The in-hospital case fatality rate in Mexico is consistent with recent reports around the world.

Age-Dependent Ocular Dominance Plasticity in Adult Mice

PubMed Central

Lehmann, Konrad; Löwel, Siegrid

2008-01-01

Background Short monocular deprivation (4 days) induces a shift in the ocular dominance of binocular neurons in the juvenile mouse visual cortex but is ineffective in adults. Recently, it has been shown that an ocular dominance shift can still be elicited in young adults (around 90 days of age) by longer periods of deprivation (7 days). Whether the same is true also for fully mature animals is not yet known. Methodology/Principal Findings We therefore studied the effects of different periods of monocular deprivation (4, 7, 14 days) on ocular dominance in C57Bl/6 mice of different ages (25 days, 90–100 days, 109–158 days, 208–230 days) using optical imaging of intrinsic signals. In addition, we used a virtual optomotor system to monitor visual acuity of the open eye in the same animals during deprivation. We observed that ocular dominance plasticity after 7 days of monocular deprivation was pronounced in young adult mice (90–100 days) but significantly weaker already in the next age group (109–158 days). In animals older than 208 days, ocular dominance plasticity was absent even after 14 days of monocular deprivation. Visual acuity of the open eye increased in all age groups, but this interocular plasticity also declined with age, although to a much lesser degree than the optically detected ocular dominance shift. Conclusions/Significance These data indicate that there is an age-dependence of both ocular dominance plasticity and the enhancement of vision after monocular deprivation in mice: ocular dominance plasticity in binocular visual cortex is most pronounced in young animals, reduced but present in adolescence and absent in fully mature animals older than 110 days of age. Mice are thus not basically different in ocular dominance plasticity from cats and monkeys which is an absolutely essential prerequisite for their use as valid model systems of human visual disorders.

Age-related Decline of Abiotic Stress Tolerance in Young Drosophila melanogaster Adults.

PubMed

Colinet, Hervé; Chertemps, Thomas; Boulogne, Isabelle; Siaussat, David

2016-12-01

Stress tolerance generally declines with age as a result of functional senescence. Age-dependent alteration of stress tolerance can also occur in early adult life. In Drosophila melanogaster, evidence of such a decline in young adults has only been reported for thermotolerance. It is not known whether early adult life entails a general stress tolerance reduction and whether the response is peculiar to thermal traits. The present work was designed to investigate whether newly eclosed D melanogaster adults present a high tolerance to a range of biotic and abiotic insults. We found that tolerance to most of the abiotic stressors tested (desiccation, paraquat, hydrogen peroxide, deltamethrin, and malathion) was high in newly eclosed adults before dramatically declining over the next days of adult life. No clear age-related pattern was found for resistance to biotic stress (septic or fungal infection) and starvation. These results suggest that newly eclosed adults present a culminating level of tolerance to extrinsic stress which is likely unrelated to immune process. We argue that stress tolerance variation at very young age is likely a residual attribute from the previous life stage (ontogenetic carryover) or a feature related to the posteclosion development. © The Author 2015.

Previous research on age-related changes in Theory of Mind (ToM) showed a decline in older adults, particularly pronounced over 75 years of age. Evidence that ToM may be enhanced in healthy aging people has been demonstrated, but no study has focused on the role of age on the effects of ToM training for elderly people. The present study was designed to examine the efficacy of a ToM training on practiced (ToM Strange Stories) and transfer tasks (ToM Animations) in both young and older adults. The study involved 127 older adults belonging to two age groups: young-old (Mage = 64.41; SD = 2.49; range: 60-69 years) and old-old (Mage = 75.66; SD = 4.38; range: 70-85 years), randomly assigned to either a ToM group or a control group condition. All participants took part in two 2-hour testing sessions and four 2-hour training sessions. Results showed that both young-old and old-old adults in the ToM group condition improved their ability to reason on complex-mental states significantly more than participants in the control group condition. This positive effect of the training was evident on practiced and transfer ToM tasks. Crucially, age did not moderate the effect of the ToM training. These findings demonstrate that young-old and old-old adults equally benefit from the ToM training. Implications for the positive effect of the ToM training in old-old adults are discussed.

Saving the Best for Last: How Adults Treat Social Partners of Different Ages

PubMed Central

Fingerman, Karen; Miller, Laura; Charles, Susan

Older adults report more positive feelings and fewer problems in their relationships than do younger adults. These positive experiences may partially reflect how people treat older adults. Social partners may treat older adults more kindly due to their sense that time remaining to interact with these older adults is limited. Younger (n = 87, aged 22 to 35) and older participants (n = 89, aged 65 to 77) indicated how positively they would behave (i.e., express affection, proffer respect, send sentimental cards) and what types of conflict strategies they would use in response to hypothetical negative interactions with two close social partners, a younger adult and an older adult. Multilevel models revealed that participants were more avoidant and less confrontational when interacting with older adults than when interacting with younger adults. Time perspective of the relationship partially mediated these age differences. Young and older participants also were more likely to select sentimental cards for older partners than for younger partners. Findings build on socioemotional selectivity theory and the social input model to suggest that social partners facilitate better relationships in late life. PMID:18573013

Ultrasound (US) measurement of the median nerve cross-sectional area (CSA) at the wrist is a useful diagnostic test for carpal tunnel syndrome (CTS). We compared median nerve normal values between samples of Indian and Dutch populations. The median nerve was examined by US at the wrist in 100 healthy volunteers in India and 137 volunteers in The Netherlands using the same protocol. Median nerve CSA at the wrist (7.0 ± 1.1 mm(2)) in the Indian cohort was lower in comparison to the Dutch cohort (8.3 ± 1.9 mm(2) ; P < 0.05). This difference was still present after controlling for age, height, and weight (P = 0.001). CSA normal values for the median nerve were different between the examined population samples even after correcting for age, height, and weight. This enforces the idea that laboratories around the world should obtain their own normative data. Copyright © 2013 Wiley Periodicals, Inc.

Adult height, dietary patterns, and healthy aging.

Background: Adult height has shown directionally diverse associations with several age-related disorders, including cardiovascular disease, cancer, decline in cognitive function, and mortality. Objective: We investigated the associations of adult height with healthy aging measured by a full spectrum of health outcomes, including incidence of chronic diseases, memory, physical functioning, and mental health, among populations who have survived to older age, and whether lifestyle factors modified such relations. Design: We included 52,135 women (mean age: 44.2 y) from the Nurses' Health Study without chronic diseases in 1980 and whose health status was available in 2012. Healthy aging was defined as being free of 11 major chronic diseases and having no reported impairment of subjective memory, physical impairment, or mental health limitations. Results: Of all eligible study participants, 6877 (13.2%) were classified as healthy agers. After adjustment for demographic and lifestyle factors, we observed an 8% (95% CI: 6%, 11%) decrease in the odds of healthy aging per SD (0.062 m) increase in height. Compared with the lowest category of height (≤1.57 m), the OR of achieving healthy aging in the highest category (≥1.70 m) was 0.80 (95% CI: 0.73, 0.87; P -trend < 0.001). In addition, we found a significant interaction of height with a prudent dietary pattern in relation to healthy aging ( P -interaction = 0.005), and among the individual dietary factors characterizing the prudent dietary pattern, fruit and vegetable intake showed the strongest effect modification ( P -interaction = 0.01). The association of greater height with reduced odds of healthy aging appeared to be more evident among women with higher adherence to the prudent dietary pattern rich in vegetable and fruit intake. Conclusions: Greater height was associated with a modest decrease in the likelihood of healthy aging. A prudent diet rich in fruit and vegetables might modify the relation. © 2017

The study purpose was to determine factors affecting aging cognitive function of 3,645 community-dwelling older adults in Korea. The Hasegawa Dementia Scale assessed aging cognitive function, blood analyses and anthropometrics assessed cardio-metabolic risk factors, and the Geriatric Depression Scale Short Form Korean Version assessed depressive symptoms. Participants with poor aging cognitive function were more likely to be in the late age group (≥75 y) and currently smoking and have a medical history of stroke, high body mass index, and high level of depressive symptoms; they were also less likely to engage in regular meals and physical activities. Regular meals and physical activities may be primary factors for clinical assessment to identify older adults at risk for aging cognitive function. With aging, depressive symptoms and other unhealthy lifestyle behaviours should be managed to prevent cognitive function disorders. © 2017 John Wiley & Sons Australia, Ltd.

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

On the Inevitability of Aging: Essentialist Beliefs Moderate the Impact of Negative Age Stereotypes on Older Adults' Memory Performance and Physiological Reactivity.

PubMed

Weiss, David

2016-07-20

The goal of this research was to investigate how individual differences in essentialist beliefs about aging affect how older adults' respond to negative age stereotypes. Essentialist beliefs about aging (EBA) define the process of aging as fixed and inevitable rather than malleable and modifiable. Two experiments including older adults tested the hypothesis that EBA moderate the effect of negative age stereotypes on older adults' memory performance and physiological reactivity. In line with predictions, results of Experiment 1 (N = 79, 61-87 years) showed that for older adults with strong EBA, the activation of negative age stereotypes (vs neutral information) led to stereotype assimilation entailing a poorer memory performance. In contrast, for older adults with non-EBA, the activation of negative age stereotypes led to stereotype reactance entailing a better memory performance. Experiment 2 (N = 41; 65-92 years) replicated this pattern and also showed that older adults who endorsed rather than rejected EBA exhibited increased systolic blood pressure reactivity when negative age stereotypes were activated. The discussion focuses on pathways through which age stereotypes impact cognitive performance and health in later adulthood, as well as ways to stimulate positive plasticity by changing EBA. © The Author 2016.

Do Older Adults Need Sleep? A Review of Neuroimaging, Sleep, and Aging Studies.

PubMed

Scullin, Michael K

2017-09-01

Sleep habits, sleep physiology, and sleep disorders change with increasing age. However, there is a longstanding debate regarding whether older adults need sleep to maintain health and daily functioning (reduced-sleep-need view). An alternative possibility is that all older adults need sleep, but that many older adults have lost the ability to obtain restorative sleep (reduced-sleep-ability view). Prior research using behavioral and polysomnography outcomes has not definitively disentangled the reduced-sleep-need and reduced-sleep-ability views. Therefore, this review examines the neuroimaging literature to determine whether age-related changes in sleep cause-or are caused by-age-related changes in brain structure, function, and pathology. In middle-aged and older adults, poorer sleep quality, greater nighttime hypoxia, and shorter sleep duration related to cortical thinning in frontal regions implicated in slow wave generation, in frontoparietal networks implicated in cognitive control, and in hippocampal regions implicated in memory consolidation. Furthermore, poor sleep quality was associated with higher amyloid burden and decreased connectivity in the default mode network, a network that is disrupted in the pathway to Alzheimer's disease. All adults need sleep, but cortical thinning and amyloidal deposition with advancing age may weaken the brain's ability to produce restorative sleep. Therefore, sleep in older adults may not always support identical functions for physical, mental, and cognitive health as in young adults.

Evaluating population-based data of hematologic malignancies (HMs) in older adults provides prognostic information for this growing demographic. Incidence rates and one- and five-year relative survival rates were examined for specific HMs among adults ages ≥75 years using data from the Surveillance, Epidemiology and End Results (SEER) Program. Hematologic malignancy cases (Hodgkin lymphoma (HL), non-Hodgkin lymphoma (NHL), multiple myeloma (MM), acute lymphocytic leukemia (ALL), chronic lymphocytic leukemia (CLL), acute myeloid leukemia (AML), and chronic myeloid leukemia (CML)) were reported to one of 18 SEER registries. Recent average annual (2010-2014) incidence rates and incidence trends from 1973 to 2014 were examined for cases ages ≥75 years. One- and five-year relative cancer survival rates were examined for adults ages ≥75 years diagnosed 2007-2013, with follow-up into 2014. From 1973 to 2014, incidence rates increased for NHL, MM, and AML, decreased for HL, and remained relatively stable for ALL, CLL, and CML among adults ages ≥75 years. The highest one- and five-year relative survival rates were observed among adults with CLL ages 75-84 years (1 year: 91.8% (95% CI = 91.8-90.8)) and 5 years: 76.5% (95% CI = 74.2-78.6)). The lowest one- and five-year survival rates were observed among adults with AML ages 75-84 (1 year: 18.2% (95% CI = 74.2-78.6) and 5 years: 2.7% (95% CI = 2.0-3.6)). Survival for older adults ages ≥75 years with HMs is poor, particularly for acute leukemia. Understanding the heterogeneity in HM outcomes among older patients may help clinicians better address the hematological cancer burden and mortality in the aging population. © 2018 The Authors.

Abstract Osteoarticular mycoses due to non-Aspergillus moulds are uncommon and challenging infections. A systematic literature review of non-Aspergillus osteoarticular mycoses was performed using PUBMED and EMBASE databases from 1970 to 2013. Among 145 patients were 111 adults (median age 48.5 [16–92 y]) and 34 pediatric patients (median age 7.5 [3–15 y]); 114 (79.7%) were male and 88 (61.9%) were immunocompromised. Osteomyelitis was due to direct inoculation in 54.5%. Trauma and puncture wounds were more frequent in children (73.5% vs 43.5%; P = 0.001). Prior surgery was more frequent in adults (27.7% vs 5.9%; P = 0.025). Vertebral (23.2%) and craniofacial osteomyelitis (13.1%) with neurological deficits predominated in adults. Lower limb osteomyelitis (47.7%) and knee arthritis (67.8%) were predominantly seen in children. Hyalohyphomycosis represented 64.8% of documented infections with Scedosporium apiospermum (33.1%) and Lomentospora prolificans (15.8%) as the most common causes. Combined antifungal therapy and surgery was used in 69% of cases with overall response in 85.8%. Median duration of therapy was 115 days (range 5–730). When voriconazole was used as single agent for treatment of hyalohyphomycosis and phaeohyphomycosis, an overall response rate was achieved in 94.1% of cases. Non-Aspergillus osteoarticular mycoses occur most frequently in children after injury and in adults after surgery. Accurate early diagnosis and long-course therapy (median 6 mo) with a combined medical-surgical approach may result in favorable outcome. PMID:26683917

To examine whether subjective sleep quality and sleep duration moderate the association between age and telomere length (TL). Participants completed a demographic and sleep quality questionnaire, followed by a blood draw. Social Neuroscience Laboratory. One hundred fifty-four middle-aged to older adults (age 45-77 y) participated. Participants were excluded if they were on immunosuppressive treatment and/or had a disease with a clear immunologic (e.g., cancer) component. N/A. Subjective sleep quality and sleep duration were assessed using the Pittsburgh Sleep Quality Index (PSQI) and TL was determined using peripheral blood mononuclear cells (PBMCs). There was a significant first-order negative association between age and TL. Age was also negatively associated with the self-reported sleep quality item and sleep duration component of the PSQI. A significant age × self-reported sleep quality interaction revealed that age was more strongly related to TL among poor sleepers, and that good sleep quality attenuated the association between age and TL. Moreover, adequate subjective sleep duration among older adults (i.e. greater than 7 h per night) was associated with TL comparable to that in middle-aged adults, whereas sleep duration was unrelated to TL for the middle-aged adults in our study. The current study provides evidence for an association between sleep quality, sleep duration, and cellular aging. Among older adults, better subjective sleep quality was associated with the extent of cellular aging, suggesting that sleep duration and sleep quality may be added to a growing list of modifiable behaviors associated with the adverse effects of aging.

The high complexity of pediatric reference ranges across age, sex, and units impairs clinical application and comparability of steroid hormone data, e.g., in congenital adrenal hyperplasia (CAH). We developed a multiples-of-median (MoM) normalization tool to overcome this major drawback in pediatric endocrinology. Liquid chromatography tandem mass spectrometry data comprising 10 steroid hormones representing 905 controls (555 males, 350 females, 0 to > 16 years) from 2 previous datasets were MoM transformed across age and sex. Twenty-three genetically proven CAH patients were included (21-hydroxylase deficiency [21OHD], n = 19; 11β-hydroxylase deficiency [11OHD], n = 4). MoM cutoffs for single steroids predicting 21OHD and 11OHD were computed and validated through new, independent patients (21OHD, n = 8; adrenal cortical carcinoma, n = 6; obesity, n = 40). 21OHD and 11OHD patients showed disease-typical, easily recognizable MoM patterns independent of age, sex, and concentration units. Two single-steroid cutoffs indicated 21OHD: 3.87 MoM for 17-hydroxyprogesterone (100% sensitivity and 98.83% specificity) and 12.28 MoM for 21-deoxycortisol (94.74% sensitivity and 100% specificity). A cutoff of 13.18 MoM for 11-deoxycortisol indicated 11OHD (100% sensitivity and 100% specificity). Age- and sex-independent MoMs are straightforward for a clinically relevant display of multi-steroid patterns. In addition, defined single-steroid MoMs can serve alone as predictors of 21OHD and 11OHD. Finally, MoM transformation offers substantial enhancement of routine and scientific steroid hormone data exchange due to improved comparability. © 2018 S. Karger AG, Basel.

Young adult survivors of childhood cancer have an increased risk for treatment-related morbidity and mortality. In this study, the authors assessed how treatment for childhood cancer affects older-adult health and health practices. One hundred seven adults treated for childhood cancer between 1947 and 1968, known to have survived past age 50 years, were identified from a single-institution cohort established in 1975. Updated vital status on eligible cases was obtained from public records. Survivors and a control group of their age-matched siblings and cousins completed a mailed survey to assess physical and social function, healthcare practices, and the prevalence of common adult illnesses. Of the 107 survivors known to be alive at age 50 years, 16 were deceased at follow-up; 7 deaths could be associated with prior treatment (second malignancy in radiation field [3], small bowel obstruction after abdominal radiation [2], and cardiac disease after chest irradiation [2]). The 55 survivors (median age, 56 years; range, 51-71 years), and 32 family controls (median age, 58 years; range, 48-70 years), reported similar health practices, health-related quality of life, and social function. However, survivors reported more frequent visits to healthcare providers (P < .05), more physical impairments (P < .05), fatigue (P = .02), hypertension (P = .001), and coronary artery disease (P = .01). An increased risk of hypertension was associated with nephrectomy during childhood (odds ratio, 18.9; 95% confidence interval, 3.0-118.8). The oldest adult survivors of childhood cancer continue to be at risk for treatment-related complications that potentially decrease their life expectancy and compromise their quality of life.

Background This review incorporates current research examining alcohol's differential effects on adolescents, adults, and aged populations in both animal and clinical models. Methods The studies presented range from cognitive, behavioral, molecular, and neuroimaging techniques, leading to a more comprehensive understanding of how acute and chronic alcohol use affects the brain throughout the life span. Results Age of life is a significant factor in determining the effect of alcohol on brain functioning. Adolescents and aged populations may be more negatively affected by heavy alcohol use when compared to adults. Conclusions Investigations limiting alcohol effects to a single age group constrains understanding of differential trajectories and outcomes following acute and chronic use. To meaningfully address the sequencing and interaction effects of alcohol and age, the field must incorporate collaborative and integrated research efforts focused on interdisciplinary questions facilitated by engaging basic and applied scientists with expertise in a range of disciplines including alcohol, neurodevelopment, and aging.

To determine whether duration and degree of weight gain are differentially associated with diabetes risk in younger versus middle-aged black and white adults. We combined data from three cohort studies: Atherosclerosis Risk in Communities (ARIC), Coronary Artery Risk Development in Young Adults (CARDIA), and the Framingham Heart Study. A total of 17,404 participants (56% women; 21% black) were stratified by baseline age (younger: ≥30 and <45 years; middle-aged: ≥45 and <60 years) and examined for incident diabetes (median follow-up 9 years). Duration and degree of gain in BMI were calculated as "BMI-years" above one's baseline BMI. Diabetes incidence per 1,000 person-years in the younger and middle-aged groups was 7.2 (95% CI 5.7, 8.7) and 24.4 (22.0, 26.8) in blacks, respectively, and 3.4 (2.8, 4.0) and 10.5 (9.9, 11.2) in whites, respectively. After adjusting for sex, baseline BMI and other cardiometabolic factors, and age and race interaction terms, gains in BMI-years were associated with higher risk of diabetes in the younger compared with middle-aged groups: hazard ratios for 1-unit increase in log BMI-years in younger versus middle-aged blacks were 1.18 (P = 0.02) and 1.02 (P = 0.39), respectively (P for interaction by age-group = 0.047), and in whites were 1.35 (P < 0.001) and 1.11 (P < 0.001), respectively (P for interaction by age-group = 0.008). Although middle-aged adults have higher rates of diabetes, younger adults are at greater relative risk of developing diabetes for a given level of duration and degree of weight gain. © 2015 by the American Diabetes Association.

Adult age differences in task switching.

2000-03-01

Age differences in 2 components of task-set switching speed were investigated in 118 adults aged 20 to 80 years using task-set homogeneous (e.g., AAAA ...) and task-set heterogeneous (e.g., AABBAABB ... ) blocks. General switch costs were defined as latency differences between heterogeneous and homogeneous blocks. whereas specific switch costs were defined as differences between switch and nonswitch trials within heterogeneous blocks. Both types of costs generalized over verbal, figural, and numeric stimulus materials; were more highly correlated to fluid than to crystallized abilities; and were not eliminated after 6 sessions of practice, indicating that they reflect basic and domain-general aspects of cognitive control. Most important, age-associated increments in costs were significantly greater for general than for specific switch costs, suggesting that the ability to efficiently maintain and coordinate 2 alternating task sets in working memory instead of 1 is more negatively affected by advancing age than the ability to execute the task switch itself.

Aging Ebbs the Flow of Thought: Adult Age Differences in Mind Wandering, Executive Control, and Self-Evaluation

Two experiments examined the relations among adult aging, mind wandering, and executive-task performance, following from surprising laboratory findings that older adults report fewer task-unrelated thoughts (TUTs) than do younger adults (e.g., Giambra, 1989; Jackson & Balota, 2011). Because older adults may experience more ability- and performance-related worry during cognitive tasks in the laboratory, and because these evaluative thoughts (known as task-related interference, “TRI”) might be sometimes misclassified by subjects as task-related, we asked subjects to distinguish task-related thoughts from TRI and TUTs when probed during ongoing tasks. In Experiment 1, younger and older adults completed either a go/no-go or a vigilance version of a sustained attention to response task (SART). Older adults reported more TRI and fewer TUTs than did younger adults while also performing more accurately. In Experiment 2, subjects completed either a 1- or 2-back version of the n-back task. Older adults again reported more TRI and fewer TUTs than younger adults in both versions, while performing better than younger adults in the 1-back and worse in the 2-back. Across experiments, older adults’ reduced TUT rates were independent of performance relative to younger adults. And, although older adults consistently reported more TRI and less mind wandering than did younger adults, overall they reported more on-task thoughts. TRI cannot, therefore, account completely for prior reports of decreasing TUTs with aging. We discuss the implications of these results for various theoretical approaches to mind-wandering.

Walking is a popular form of physical activity that can bring many public health benefits. It can be even more beneficial to those who are currently obese or overweight. However, many barriers discourage people from walking, ranging from lack of motivation to unsafe neighborhood environments, and such barriers vary with age. This study addresses barriers and motivators to walking among overweight and obese adults, and examines their age variations. Particular emphasis was given to modifiable environmental factors as the priority intervention targets. A survey of 161 overweight and obese adults recruited from a large integrated healthcare system in central Texas provided data on walking, demographics, motivators and barriers. Descriptive statistics and correlation analysis were conducted. The respondents had a mean age of 48.4 (20-86), and were predominantly female (80.8%), non-Hispanic White (86.0%), and obese (mean BMI = 32.5). Popular environmental barriers to walking were: bad weather, inadequate lighting, no shade, unattended dogs, disconnected sidewalks, poor walking surfaces, no interesting places to walk nearby, and no benches (74.5-38.5%). Even and smooth walking surfaces and benches were more frequently reported by older adults as motivators. Proximity to recreational facilities was a stronger motivator for younger adults. Two safety related barriers, fear of injury (older adults) and traffic safety concerns (younger adults), also showed significant age differences. Overweight and obese adults experience substantial environmental barriers to walking, but many of them are modifiable. Observed age variations suggest that future interventions may be more effective if tailored to address age-specific barriers.

An ultrahigh-frequency (70 MHZ) ultrasound device has recently been approved for human use. This study seeks to determine whether this device facilitates counting of fascicles within the median nerve at the wrist. Twenty healthy volunteers underwent imaging of the median nerve at the wrist bilaterally. The number of fascicles in each nerve was counted by two independent raters. The mean fascicle number was 22.68. Correlation was strong between the two raters (r = 0.68, P < 0.001). Age, sex, body mass index, and nerve area did not predict fascicle number. Those with bifid median nerves and persistent median arteries had lower fascicle density than those without anatomic anomalies (1.79 vs. 2.29; P = 0.01). Fascicles within the median nerve at the wrist can be readily imaged. Ultrahigh-frequency ultrasound technology may be informative in a variety of disorders affecting the peripheral nervous system.

Although a risk of occupational musculoskeletal diseases has been identified with age-related strength degradation, strength measures from working group are somewhat sparse. This is especially true for the lower extremity strength measures in dynamic conditions (i.e., isokinetic). The objective of this study was to quantify the lower extremity muscle strength characteristics of three age groups (young, middle, and the elderly). Total of 42 subjects participated in the study: 14 subjects for each age group. A commercial dynamometer was used to evaluate isokinetic and isometric strength at ankle and knee joints. 2 × 2 (Age group (younger, middle-age, and older adult groups) × Gender (male and female)) between-subject design and Post-hoc analysis were performed to evaluate strength differences among three age groups. Post-hoc analysis indicated that, overall, middle-age workers’ leg strengths (i.e. ankle and knee muscles) were significantly different from younger adults while middle-age workers’ leg strengths were virtually identical to older adults’ leg strengths. These results suggested that, overall, 14 middle-age workers in the present study could be at a higher risk of musculoskeletal injuries. Future studies looking at the likelihood of musculoskeletal injuries at different work places and from different working postures at various age levels should be required to validate the current findings. The future study would be a valuable asset in finding intervention strategies such that middle-age workers could stay healthier longer. PMID:20436934

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.

Median and ulnar muscle and sensory evoked potentials.

Felsenthal, G

1978-08-01

The medical literature was reviewed to find suggested clinical applications of the study of the amplitude of evoked muscle action potentials (MAP) and sensory action potentials (SAP). In addition, the literature was reviewed to ascertain the normal amplitude and duration of the evoked MAP and SAP as well as the factors affecting the amplitude: age, sex, temperature, ischemia. The present study determined the normal amplitude and duration of the median and ulnar MAP and SAP in fifty normal subjects. The amplitude of evoked muscle or sensory action potentials depends on multiple factors. Increased skin resistance, capacitance, and impedance at the surface of the recording electrode diminishes the amplitude. Similarly, increased distance from the source of the action potential diminishes its amplitude. Increased interelectrode distance increases the amplitude of the bipolarly recorded sensory action potential until a certain interelectrode distance is exceeded and the diphasic response becomes tri- or tetraphasic. Artifact or poor technique may reduce the potential difference between the recording electrodes or obscure the late positive phase of the action potential and thus diminish the peak to peak amplitude measurement. Intraindividual comparison indicated a marked difference of amplitude in opposite hands. The range of the MAP of the abductor pollicis brevis in one hand was 40.0--100% of the response in the opposite hand. For the abductor digiti minimi, the MAP was 58.5--100% of the response of the opposite hand. The median and ulnar SAP was between 50--100% of the opposite SAP. Consequent to these findings the effect of hand dominance on the amplitude of median and ulnar evoked muscle and sensory action potentials was studied in 41 right handed volunteers. The amplitudes of the median muscle action potential (p less than 0.02) and the median and ulnar sensory action potentials (p less than 0.001) were significantly less in the dominant hand. There was no

Healthy aging is typically accompanied by a decrease in the motor capacity. Although the disrupted neural representations and performance of movement have been observed in older age in previous studies, the relationship between the functional integration of sensory-motor (SM) system and aging could be further investigated. In this study, we examine the impact of healthy aging on the resting-state functional connectivity (rsFC) of the SM system, and investigate as to how aging is affecting the rsFC in SM network. The SM network was identified and evaluated in 52 healthy older adults and 51 younger adults using two common data analytic approaches: independent component analysis and seed-based functional connectivity (seed at bilateral M1 and S1). We then evaluated whether the altered rsFC of the SM network could delineate trajectories of the age of older adults using a machine learning methodology. Compared with the younger adults, the older demonstrated reduced functional integration with increasing age in the mid-posterior insula of SM network and increased rsFC among the sensorimotor cortex. Moreover, the reduction in the rsFC of mid-posterior insula is associated with the age of older adults. Critically, the analysis based on two-aspect connectivity-based prediction frameworks revealed that the age of older adults could be reliably predicted by this reduced rsFC. These findings further indicated that healthy aging has a marked influence on the SM system that would be associated with a reorganization of SM system with aging. Our findings provide further insight into changes in sensorimotor function in the aging brain.

Influence of Central Obesity Assessed by Conicity Index on Lung Age in Young Adults.

PubMed

Shenoy, Usha; Jagadamba

2017-04-01

Central obesity is an emerging public health problem in young adults which compromises lung mechanics. Conicity Index (CI) is a simple anthropometric measure to assess central adiposity. The concept of lung age relates to a person's current lung function at which his/her lung function would be considered abnormal in relation to the present actual age. To determine the effect of central obesity by CI on lung age in young adults. A total of 319 young adults in the age group 18-25 years were recruited for this cross-sectional observational study. Written informed consent and Institutional Ethical Clearance (IEC) approval were obtained. Anthropometric parameters were measured and CI was calculated using the following formula: CI = Waist Circumference (WC) (m)/ [0.109 X√ {Bodyweight (kg)/ Height (m)}] where 0.109 is a constant. Spirometry was performed and all the lung volumes and capacities were obtained. There was a significant increase in mean values of CI in obese young adults compared to non obese (1.36±0.15 and 1.16±0.08, p<0.001). The effect of central obesity on lung age in young adults was compared using an independent t-test. Mean of lung age was significantly higher in centrally obese young adults compared to non obese 23.87±3.03 and 21.30±2.6, p<0.001) which was statistically significant. Lung age is significantly increased in centrally obese young adults compared to non obese. Hence, lung age can be used as a potential psychological tool to show an individual with central obesity that there is premature aging of their lungs.

The impact of age stereotypes on source monitoring in younger and older adults.

In 2 experiments, we examined reliance on age stereotypes when reconstructing the sources of statements. Two sources presented statements (half typical for a young adult, half for an old adult). Afterward, the sources' ages-23 and 70 years-were revealed and participants completed a source-monitoring task requiring attribution of statements to the sources. Multinomial model-based analyses revealed no age-typicality effect on source memory; however, age-typicality biased source-guessing: When not remembering the source, participants predominantly guessed the source for whose age the statement was typical. Thereby, people retrospectively described the sources as having made more statements that fit with stereotypes about their age group than they had truly made. In Experiment 1, older (60-84 years) participants' guessing bias was stronger than younger (17-26 years) participants', but they also had poorer source memory. Furthermore, older adults with better source memory were less biased than those with poorer source memory. Similarly, younger adults' age-stereotype reliance was larger when source memory was impaired in Experiment 2. Thus, age stereotypes bias source attributions, and individuals with poor source memory are particularly prone to this bias, which may contribute to the maintenance of age stereotypes over time.

The population of adults accessing opioid treatment is growing older, but exact estimates vary widely, and little is known about the characteristics of the aging treatment population. Further, there has been little research regarding the epidemiology, healt h status, and functional impairments in this population. To determine the utilization of opioid treatment services by older adults in New York City. This study used administrative data from New York State licensed drug treatment programs to examine overall age trends and characteristics of older adults in opioid treatment programs in New York City from 1996 to 2012. We found significant increases in utilization of opioid treatment programs by older adults in New York City. By 2012, those aged 50-59 made up the largest age group in opioid treatment programs. Among older adults there were notable shifts in demographic background including gender and ethnicity, and an increase in self-reported impairments. More research is needed to fully understand the specific characteristics and needs of older adults with opioid dependence.

In the last two centuries, age at menarche has decreased in several European populations, whereas adult height has increased. It is unclear whether these trends have ceased in recent years or how age at menarche and height are related in individuals. In this study, the authors first investigated trends in age at menarche and adult height among 286,205 women from nine European countries by computing the mean age at menarche and height in 5-year birth cohorts, adjusted for differences in socioeconomic status. Second, the relation between age at menarche and height was estimated by linear regression models, adjusted for age at enrollment between 1992 and 1998 and socioeconomic status. Mean age at menarche decreased by 44 days per 5-year birth cohort (beta = -0.12, standard error = 0.002), varying from 18 days in the United Kingdom to 58 days in Spain and Germany. Women grew 0.29 cm taller per 5-year birth cohort (standard error = 0.007), varying from 0.42 cm in Italy to 0.98 cm in Denmark. Furthermore, women grew approximately 0.31 cm taller when menarche occurred 1 year later (range by country: 0.13-0.50 cm). Based on time trends, more recent birth cohorts have their menarche earlier and grow taller. However, women with earlier menarche reach a shorter adult height compared with women who have menarche at a later age.

To evaluate outcome of prophylactic clotting factor replacement in children with haemophilia, the Haemophilia Joint Health Score (HJHS) was developed aiming at scoring early joint changes in children aged 4-18. The HJHS has been used for adults on long-term prophylaxis but interpretation of small changes remains difficult. Some changes in these patients may be due to sports-related injuries. Evaluation of HJHS score in healthy adults playing sports could improve the interpretation of this score in haemophilic patients. The aim of this study was to evaluate the HJHS scores in a cohort of young, healthy men participating in sports. Concomitant with a project collecting MRI images of ankles and knees in normal young adults, HJHS scores were assessed in 30 healthy men aged 18-26, participating in sports one to three times per week. One physiotherapist assessed their clinical function using the HJHS 2.1. History of joint injuries was documented. MRI images were scored by a single radiologist, using the International Prophylaxis Study Group additive MRI score. Median age of the study group was 24.3 years (range 19.0-26.4) and median frequency of sports activities was three times per week (range 1-4). Six joints (five knees, one ankle) had a history of sports-related injury. The median overall HJHS score was 0 out of 124 (range 0-3), with 60% of subjects showing no abnormalities on HJHS. All joints were normal on MRI. These results suggest that frequent sports participation and related injuries are not related with abnormalities in HJHS scores. © 2013 John Wiley & Sons Ltd.

Physical activity declines across the adult life span despite the well-established links between physical activity and health-related, psychological, cognitive, and social benefits. We contrasted the beliefs young and older adults hold about how aging affects both physical abilities and physical activity and determined whether older adults' beliefs about physical aging relate to their engagement in physical activity. Using visual rating scales, 56 young and 49 community-dwelling older adults indicated the extent to which a typical woman or typical man aged 20-90 possesses six different physical abilities and engages in three different types of physical activity. Stereotypes of physical aging were ability- and activity-specific, and older adults endorsed more positive views than their younger peers. Stereotypical beliefs predicted older adults' engagement in moderate-intensity activity. This study offers intriguing avenues for future research and suggests that better understanding physical aging stereotypes may contribute toward designing interventions that promote lifelong physical activity.

Spexin is a newly identified neuropeptide that is involved in satiety control, glucose, and lipids metabolism. It has also been related to human diseases, such as obesity and type 2 diabetes. However, whether spexin changes with age or not is still unclear. The aim of this study is to investigate the relationship between circulating spexin levels and age and to study their interaction effects on body mass index (BMI), fasting glucose, and -lipids. This is a cross-sectional study, including 68 healthy adult women whose ages are in a wide range (minimum: 23; median: 38.5; maximum: 64). The serum spexin levels were measured by an enzyme-linked immunosorbent assay. Fasting glucose, total cholesterol, triglycerides (TG), alkaline phosphatase, alanine aminotransferase, aspartate aminotransferase, urea, and creatinine were measured by routine biochemical test. Shapiro-Wilk's test, Spearman and Pearson correlation analyses, χ 2 test, and two-way analysis of variance were used to interpret the data. Serum spexin levels are significantly correlated with age (Spearman r = -0.277, P = 0.022), BMI (Spearman r = -0.445, P < 0.001), fasting glucose (Spearman r = -0.302, P = 0.014), and TG (Spearman r = -0.324, P = 0.008). Spexin levels independently predict the risk of high BMI and high fasting glucose. No interaction effects of spexin and age on BMI and fasting glucose were found. Circulating spexin levels decrease with age, suggesting a possible role of this peptide in aging-related functions and disorders. Further investigations are needed to expand the clinical significance of this finding.

Researchers have been examining the relationship between obesity and hypertension. However, whether overall or abdominal obesity better explains senior adults' hypertension has not been studied. The purpose of the study was to examine whether body mass index or waist circumference better predicts hypertension in Chinese senior adults and how the magnitude of the relationship is attenuated as they continue to age. The study was based on the 2010 National Physique Monitoring data. There were 7,542 senior adults aged 60-69 years living in urban, suburban, and rural areas of Shanghai City. The participants were categorized into five age groups: 60-61, 62-63, 64-65, 66-67, and 68-69 years. The percentage of participants who had hypertension increased as people aged, which was mainly caused by the increase of systolic blood pressure. Logistic regression analysis showed that when body mass index or waist circumference was entered into the model, both were significant predictors for hypertension (p < 0.05). However, when body mass index and waist circumference were mutually entered into the model, body mass index was the only important predictor (p < 0.05). The values of odds ratios were found to decrease from the 60-61 to 68-69 years age groups. More senior adults have hypertension as they age. Body mass index, and not waist circumference, better predicts Chinese senior adults' hypertension. However, age attenuates the effects of obesity on hypertension as the senior adults continue to age.

Background : This study aimed to profile the epidemiology of injury among preschool-aged and school-aged children in comparison to those in adults. Methods : According to the Trauma Registry System of a level I trauma center, the medical data were retrieved from 938 preschool-aged children (aged less than seven years), 670 school-aged children (aged 7⁻12 years), and 16,800 adults (aged 20⁻64 years) between 1 January 2009 and 31 December 2016. Two-sided Pearson’s, chi-squared, and Fisher’s exact tests were used to compare categorical data. A one-way analysis of variance (ANOVA) with the Games-Howell post-hoc test was used to assess the differences in continuous variables among different groups of patients. The mortality outcomes of different subgroups were assessed by a multivariable regression model under the adjustment of sex, injury mechanisms, and injury severity. Results : InFsupppjury mechanisms in preschool-aged and school-aged children were remarkably different from that in adults; in preschool-aged children, burns were the most common cause of injury requiring hospitalization (37.4%), followed by falls (35.1%) and being struck by/against objects (11.6%). In school-aged children, injuries were most commonly sustained from falls (47.8%), followed by bicycle accidents (14%) and being struck by/against objects (12.5%). Compared to adults, there was no significant difference of the adjusted mortality of the preschool-aged children (AOR = 0.9; 95% CI 0.38⁻2.12; p = 0.792) but there were lower adjusted odds of mortality of the school-aged children (AOR = 0.4; 95% CI 0.10⁻0.85; p = 0.039). The school-aged children had lower odds of mortality than adults (OR, 0.2; 95% CI, 0.06⁻0.74; p = 0.012), but such lower odds of risk of mortality were not found in preschool-aged children (OR, 0.7; 95% CI, 0.29⁻1.81; p = 0.646). Conclusions : This study suggests that specific types of injuries from different injury mechanisms are predominant among

Median barrier crash severity: some new insights.

PubMed

Hu, Wen; Donnell, Eric T

2010-11-01

Median barrier is used to prevent cross-median crashes on divided highways. Although it is well documented that crash frequencies increase after installing median barrier, little is known about median barrier crash severity outcomes. The present study estimated a nested logit model of median barrier crash severity using 5 years of data from rural divided highways in North Carolina. Vehicle, driver, roadway, and median cross-section design data were factors considered in the model. A unique aspect of the data used to estimate the model was the availability of median barrier placement and median cross-slope data, two elements not commonly included in roadway inventory data files. The estimation results indicate that collisions with a cable median barrier increase the probability of less-severe crash outcomes relative to collisions with a concrete or guardrail median barrier. Increasing the median barrier offset was associated with a lower probability of severe crash outcomes. The presence of a cable median barrier installed on foreslopes that were between 6H:1V and 10H:1V were associated with an increase in severe crash probabilities when compared to cable median barrier installations on foreslopes that were 10H:1V or flatter. 2010 Elsevier Ltd.

Myelin degeneration is one of the characteristics of aging and degenerative diseases. This study investigated age-related alterations in expression of myelin basic protein (MBP) in the hippocampal subregions (dentate gyrus, CA2/3 and CA1 areas) of gerbils of various ages; young (1 month), adult (6 months) and aged (24 months), using western blot and immunohistochemistry. Western blot results showed tendencies of age-related reductions of MBP levels. MBP immunoreactivity was significantly decreased with age in synaptic sites of trisynaptic loops, perforant paths, mossy fibers, and Schaffer collaterals. In particular, MBP immunoreactive fibers in the dentate molecular cell layer (perforant path) was significantly reduced in adult and aged subjects. In addition, MBP immunoreactive mossy fibers in the dentate polymorphic layer and in the CA3 striatum radiatum was significantly decreased in the aged group. Furthermore, we observed similar age-related alterations in the CA1 stratum radiatum (Schaffer collaterals). However, the density of MBP immunoreactive fibers in the dentate granular cell layer and CA stratum pyramidale was decreased with aging. These findings indicate that expression of MBP is age-dependent and tissue specific according to hippocampal layers. PMID:29046699

2017-02-01

To prevent onset of age-related diseases and physical and cognitive decline, interventions to slow human aging and extend health span must eventually be applied to people while they are still young and healthy. Yet most human aging research examines older adults, many with chronic disease, and little is known about aging in healthy young humans. This article explains how this knowledge gap is a barrier to extending health span and puts forward the case that geroscience should invest in researching the pace of aging in young adults. As one illustrative example, we describe an initial effort to study the pace of aging in a young-adult birth cohort by using repeated waves of biomarkers collected across the third and fourth decades to quantify the pace of coordinated physiological deterioration across multiple organ systems (eg, pulmonary, periodontal, cardiovascular, renal, hepatic, metabolic, and immune function). Findings provided proof of principle that it is possible to quantify individual variation in the pace of aging in young adults still free of age-related diseases. This article articulates research needs to improve longitudinal measurement of the pace of aging in young people, to pinpoint factors that slow or speed the pace of aging, to compare pace of aging against genomic clocks, to explain slow-aging young adults, and to apply pace of aging in preventive clinical trials of antiaging therapies. This article puts forward a research agenda to fill the knowledge gap concerning lifelong causes of aging. © The Author 2016.

Identifying the factors that are associated with health-promoting behaviours in older adults is necessary to increase their willingness and motivation to participate in health-promotion activities. Understanding context-specific attitudes in relation to their influence on health-promoting behaviours is crucial in designing efficient interventions that foster health-promoting behaviours among older adults. This study aimed to examine the relationships between attitudes towards aging and health-promoting behaviours in older adults in Turkey. The study used a descriptive-correlational design. A convenience sample of 448 community-dwelling older adults who were 65 years and older and cognitively intact were selected from 6 family health centres in the city of Denizli in Turkey. The data were collected between March and June of 2014 using the Attitudes to Aging Questionnaire and the Health-Promoting Lifestyle Profile II. Multiple linear regression analysis was performed to explore the predictors of health-promoting behaviours. Attitudes toward aging, the psychosocial loss subscale, and education were statistically significant predictors of health-promoting behaviours. Attitudes toward aging were the strongest predictor of health-promoting behaviours in older adults. Attitude towards aging is a factor that affects health-promoting behaviours, and it should be considered during interventions for improving health promoting behaviours. © 2017 John Wiley & Sons Australia, Ltd.

Reducing Ageism: Education About Aging and Extended Contact With Older Adults.

Lytle, Ashley; Levy, Sheri R

2017-11-19

Ageism is of increasing concern due to the growing older population worldwide and youth-centered focus of many societies. The current investigation tested the PEACE (Positive Education about Aging and Contact Experiences) model for the first time. Two online experimental studies examined 2 key factors for reducing ageism: education about aging (providing accurate information about aging) and extended contact (knowledge of positive intergenerational contact) as well as their potential combined effect (education plus extended contact). In Study 1, 354 undergraduates in all 3 experimental conditions (vs. control participants) reported less negative attitudes toward older adults (delayed post-test) and greater aging knowledge (immediate and delayed post-tests), when controlling for pre-study attitudes. In Study 2, 505 national community participants (ages 18-59) in all experimental conditions (vs. control participants) reported less negative attitudes toward older adults (immediate post-test) and greater aging knowledge (immediate and delayed post-tests). In summary, across 2 online studies, education about aging and knowledge of intergenerational extended contact improved attitudes toward older adults and aging knowledge. Thus, brief, online ageism-reduction strategies can be an effective way to combat ageism. These strategies hold promise to be tested in other settings, with other samples, and to be elaborated into more in-depth interventions that aim to reduce ageism in everyday culture. © The Author 2017.

2017-05-01

Astrocytes are dynamic cells that maintain brain homeostasis, regulate neurotransmitter systems, and process synaptic information, energy metabolism, antioxidant defenses, and inflammatory response. Aging is a biological process that is closely associated with hippocampal astrocyte dysfunction. In this sense, we demonstrated that hippocampal astrocytes from adult and aged Wistar rats reproduce the glial functionality alterations observed in aging by evaluating several senescence, glutamatergic, oxidative and inflammatory parameters commonly associated with the aging process. Here, we show that the p21 senescence-associated gene and classical astrocyte markers, such as glial fibrillary acidic protein (GFAP), vimentin, and actin, changed their expressions in adult and aged astrocytes. Age-dependent changes were also observed in glutamate transporters (glutamate aspartate transporter (GLAST) and glutamate transporter-1 (GLT-1)) and glutamine synthetase immunolabeling and activity. Additionally, according to in vivo aging, astrocytes from adult and aged rats showed an increase in oxidative/nitrosative stress with mitochondrial dysfunction, an increase in RNA oxidation, NADPH oxidase (NOX) activity, superoxide levels, and inducible nitric oxide synthase (iNOS) expression levels. Changes in antioxidant defenses were also observed. Hippocampal astrocytes also displayed age-dependent inflammatory response with augmentation of proinflammatory cytokine levels, such as TNF-α, IL-1β, IL-6, IL-18, and messenger RNA (mRNA) levels of cyclo-oxygenase 2 (COX-2). Furthermore, these cells secrete neurotrophic factors, including glia-derived neurotrophic factor (GDNF), brain-derived neurotrophic factor (BDNF), S100 calcium-binding protein B (S100B) protein, and transforming growth factor-β (TGF-β), which changed in an age-dependent manner. Classical signaling pathways associated with aging, such as nuclear factor erythroid-derived 2-like 2 (Nrf2), nuclear factor kappa B (NFκ

A comparison of freeway median crash frequency, severity, and barrier strike outcomes by median barrier type.

Russo, Brendan J; Savolainen, Peter T

2018-08-01

Median-crossover crashes are among the most hazardous events that can occur on freeways, often resulting in severe or fatal injuries. The primary countermeasure to reduce the occurrence of such crashes is the installation of a median barrier. When installation of a median barrier is warranted, transportation agencies are faced with the decision among various alternatives including concrete barriers, beam guardrail, or high-tension cable barriers. Each barrier type differs in terms of its deflection characteristics upon impact, the required installation and maintenance costs, and the roadway characteristics (e.g., median width) where installation would be feasible. This study involved an investigation of barrier performance through an in-depth analysis of crash frequency and severity data from freeway segments where high-tension cable, thrie-beam, and concrete median barriers were installed. A comprehensive manual review of crash reports was conducted to identify crashes in which a vehicle left the roadway and encroached into the median. This review also involved an examination of crash outcomes when a barrier strike occurred, which included vehicle containment, penetration, or re-direction onto the travel lanes. The manual review of crash reports provided critical supplementary information through narratives and diagrams not normally available through standard fields on police crash report forms. Statistical models were estimated to identify factors that affect the frequency, severity, and outcomes of median-related crashes, with particular emphases on differences between segments with varying median barrier types. Several roadway-, traffic-, and environmental-related characteristics were found to affect these metrics, with results varying across the different barrier types. The results of this study provide transportation agencies with important guidance as to the in-service performance of various types of median barrier. Copyright © 2018 Elsevier Ltd. All rights

Objectives The aim of this study was to evaluate the development of impaired median nerve function in relation to hand-intensive seasonal work. We hypothesized that at end-season, median nerve conduction would be impaired and then recover within weeks. Methods Using nerve conduction studies (NCS), we examined median nerve conduction before, during, and after engaging in 22 days of mink skinning. For a subgroup, we used goniometry and surface electromyography to characterize occupational mechanical exposures. Questionnaire information on symptoms, disability, and lifestyle factors was obtained. Results The study comprised 11 male mink skinners with normal median nerve conduction at pre-season (mean age 35.7 years, mean number of seasons with skinning 8.9 years). Mink skinning was characterized by a median angle of wrist flexion/extension of 16º extension, a median velocity of wrist flexion/extension of 22 °/s, and force exertions of 11% of maximal voluntary electrical activity. At end-season, mean distal motor latency (DML) had increased 0.41 ms (P<0.001), mean sensory nerve conduction velocity (SNCV) digit 2 had decreased 6.3 m/s (P=0.004), and mean SNCV digit 3 had decreased 6.2 m/s (P=0.01); 9 mink skinners had decreases in nerve conduction, 5 fulfilled electrodiagnostic criteria and 4 fulfilled electrodiagnostic and clinical criteria (a positive Katz hand diagram) for carpal tunnel syndrome (CTS). Three to six weeks post-season, the changes had reverted to normal. Symptom and disability scores showed corresponding changes. Conclusions In this natural experiment, impaired median nerve conduction developed during 22 days of repetitive industrial work with moderate wrist postures and limited force exertion. Recovery occurred within 3-6 weeks post-season.

With the growing population of older adults as a potential user group of mHealth, the need increases for mHealth interventions to address specific aging characteristics of older adults. The existence of aging barriers to computer use is widely acknowledged. Yet, usability studies show that mHealth still fails to be appropriately designed for older adults and their expectations. To enhance designs of mHealth aimed at older adult populations, it is essential to gain insight into aging barriers that impact the usability of mHealth as experienced by these adults. This study aims to synthesize literature on aging barriers to digital (health) computer use, and explain, map and visualize these barriers in relation to the usability of mHealth by means of a framework. We performed a scoping review to synthesize and summarize reported physical and functional age barriers in relation to digital (mobile) health applications use. Aging barriers reported in the literature were mapped onto usability aspects categorized by Nielsen to explain their influence on user experience of mHealth. A framework (MOLD-US) was developed summarizing the evidence on the influence of aging barriers on mHealth use experienced by older adults. Four key categories of aging barriers influencing usability of mHealth were identified: cognition, motivation, physical ability and perception. Effective and satisfactory use of mHealth by older adults is complicated by cognition and motivation barriers. Physical ability and perceptual barriers further increase the risk of user errors and fail to notice important interaction tasks. Complexities of medical conditions, such as diminished eye sight related to diabetes or deteriorated motor skills as a result of rheumatism, can cause errors in user interaction. This research provides a novel framework for the exploration of aging barriers and their causes influencing mHealth usability in older adults. This framework allows for further systematic empirical testing

GPU Accelerated Vector Median Filter

Noise reduction is an important step for most image processing tasks. For three channel color images, a widely used technique is vector median filter in which color values of pixels are treated as 3-component vectors. Vector median filters are computationally expensive; for a window size of n x n, each of the n(sup 2) vectors has to be compared with other n(sup 2) - 1 vectors in distances. General purpose computation on graphics processing units (GPUs) is the paradigm of utilizing high-performance many-core GPU architectures for computation tasks that are normally handled by CPUs. In this work. NVIDIA's Compute Unified Device Architecture (CUDA) paradigm is used to accelerate vector median filtering. which has to the best of our knowledge never been done before. The performance of GPU accelerated vector median filter is compared to that of the CPU and MPI-based versions for different image and window sizes, Initial findings of the study showed 100x improvement of performance of vector median filter implementation on GPUs over CPU implementations and further speed-up is expected after more extensive optimizations of the GPU algorithm .

Intertemporal Choice Behavior in Emerging Adults and Adults: Effects of Age Interact with Alcohol Use and Family History Status

2015-01-01

Adults with alcohol use disorders (AUDs) show marked immediate reward selection (or “Now”) bias in intertemporal choice tasks. This Now bias persists long into abstinence, suggesting an irreversible consequence of chronic alcohol abuse or a pre-existing AUD intermediate phenotype. However, some data show substantial Now bias among emerging adults (18–25), regardless of drinking behavior, suggesting age-dependent effects on Now bias. The objectives of the present study were to determine (1) whether Now bias is greater among emerging adults relative to adults, (2) whether any such age effect on Now bias is diminished in sub-clinical heavy alcohol users, and (3) whether having a problem drinking first degree relative is independently associated with elevated Now bias. To achieve these objectives, we used an intertemporal choice task to quantify Now bias in n = 237 healthy participants (ages 18–40; 50% female), and a wide range of non-zero alcohol use, based on the Alcohol Use Disorders Identification Test (AUDIT). We found that among non-heavy drinkers, Now bias inversely correlated with age; this relationship was not present among heavy drinkers. We found no significant relationship between AUDIT score and Now bias among emerging adults, but AUDIT scores and Now bias were positively correlated among 26–40 year olds. Additionally, non-heavy drinking adults who reported a problem drinking first degree relative showed greater Now bias compared to those not reporting familial problem drinking. While not definitive, these findings lend support for elevated Now bias in adulthood as an intermediate phenotype for AUDs. Moreover, non-additive effects of age and heavy drinking on Now bias suggest perturbations in largely common neural circuits in both groups. PMID:26635580

Aging adults are vulnerable to the effects of a negative emotional state. The relaxation response (RR) is a mind-body intervention that counteracts the harmful effects of stress. Previous studies with relaxation techniques have shown the non-pharmacological benefit of reducing stress and improving the memory of healthy older adults. Our pilot study evaluated whether a RR training program would decrease anxiety levels, improve attention, declarative memory performance and/or decrease salivary cortisol levels in healthy older adults. Fifteen adults participated and were randomly assigned to a RR training or control groups. Mean age was 71.3 years and mean education level was 17.9 years. Reaction time on a simple attention/psychomotor task was significantly improved (p<0.0025) with RR training, whereas there was no significant improvement on complex tasks of attention, verbal, or visual declarative memory tests. Self-reported state anxiety levels showed a marginally significant reduction (p<0.066). All subjects' salivary cortisol levels were within low-normal range and did not significantly change. Our 5-week program in highly educated, mobile, healthy, aging adults significantly improved performance on a simple attention task.

Asthma self-management education improves asthma-related outcomes. We conducted this analysis to evaluate variation in the percentages of adults with active asthma reporting components of asthma self-management education by age at asthma onset. Data from 2011 to 2012 Asthma Call-back Surveys were used to estimate percentages of adults with active asthma reporting six components of asthma self-management education. Components of asthma self-management education include having been taught to what to do during an asthma attack and receiving an asthma action plan. Differences in the percentages of adults reporting each component and the average number of components reported across categories of age at asthma onset were estimated using linear regression, adjusted for age, education, race/ethnicity, sex, smoking status, and years since asthma onset. Overall, an estimated 76.4% of adults with active asthma were taught what to do during an asthma attack and 28.7% reported receiving an asthma action plan. Percentages reporting each asthma self-management education component declined with increasing age at asthma onset. Compared with the referent group of adults whose asthma onset occurred at 5-14 years of age, the percentage of adults reporting being taught what to do during an asthma attack was 10% lower among those whose asthma onset occurred at 65-93 years of age (95% CI: -18.0, -2.5) and the average number of components reported decreased monotonically across categories of age at asthma onset of 35 years and older. Among adults with active asthma, reports of asthma self-management education decline with increasing age at asthma onset.

Contextualizing Psychosocial Determinants of Alcohol Use by Age Cohorts of Adults Living With HIV, Ages 50 and Older.

PubMed

Mannes, Zachary L; Burrell, Larry E; Dunne, Eugene M; Hearn, Lauren E; Whitehead, Nicole Ennis

We examined the influence of age on associations between affective states, social support, and alcohol use by age cohorts. We recruited 96 older Black adults living with HIV from the southeastern United States in 2013 and 2014. Participants completed questionnaires assessing demographics, psychological function, and substance use. Hierarchical regression analyses assessed the relationship between psychosocial factors and alcohol use in a 50- to 59-year-old group, and a 60-years-and-older age group. After controlling for covariates, trait anger, state anger, and life stress were positively associated with alcohol consumption in the younger group, while social support was negatively associated with alcohol consumption in the older group. Interventions should target negative affective states in 50- to 59-year-old adults with HIV, and preserve social support for adults with HIV as they age, as such interventions will likely have an impact on these individuals' alcohol consumption and longstanding quality of life.

Theory of mind and the Ultimatum Game in healthy adult aging.

PubMed

Girardi, Alessandra; Sala, Sergio Della; MacPherson, Sarah E

2018-01-01

The Ultimatum Game assesses decision-making involved in cooperative interactions with others. However, little is known about the role that the ability to understand other people's intentions plays in these interactions. This study examined performance on the Ultimatum Game and theory of mind (ToM) tasks in younger and older adults. Age differences were not found on the ToM tasks, and a lack of variability in performance prevented analyses of the relationships between performance on the Ultimatum Game and ToM. However, age differences were found on the Ultimatum Game, with older adults accepting more unfair offers. Yet, the two age groups did not differ in their appreciation of fairness, as assessed using subjective fairness ratings. These findings suggest that older adults are more rational in their behavior, accepting unfair offers even when they know they are unfair, as it is in their self-interest to accept small monetary values rather than nothing at all.

The life expectancy of patients with congenital heart disease (CHD) has significantly improved with advances in their paediatric medical care. Mortality patterns are changing as a result. Our study aims to describe survival and causes of death in a contemporary cohort of adult patients with CHD. We reviewed 3068 patients in our adult CHD database (age ≥16 years, seen at least once in our centre between 2000 and 2015), and documented the number and causes of death, via Australia's National Death Index. Survival and mortality patterns were analysed by complexity of CHD and by underlying congenital diagnosis. Our cohort comprised 3068 adult patients (53% male). The distribution of patients (per the Bethesda classification) was 47% simple, 34% moderate and 18% complex (1% not classifiable). Over a median follow-up of 6.2 years (IQR 3.5-10.4), 341 patients (11%) died with an incidence of 0.4 deaths/100 patient years (py). Survival was significantly worse with increasing complexity of CHD (p<0.001); mortality rate in the simple group was 0.3 deaths/100 py with a median age of death 70 years, and in the complex group was 1.0 death/100 py with a median age of death 34 years. Overall, non-cardiac causes of death outnumbered cardiac causes, at 54% and 46%, respectively. The leading single cause of death was heart failure (17%), followed by malignancy (13%). Simple adult CHD patients mostly died due to non-cardiac causes such as malignancy. Perioperative mortality only accounted for 5% of deaths. Premature death is common in adults with CHD. Although heart failure remains the most common cause of death, in the contemporary era in a specialist CHD centre, non-cardiac related deaths outnumber cardiac deaths, particularly in those with simple CHD lesions. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

Adult film work involves multiple sex partners, unprotected intercourse and frequent oral/rectal contact. Data on sexual networks and sexual behaviors of adult film performers (AFP) are limited. From August 2012 to May 2013, AFPs in Los Angeles, CA, seeking care at 2 clinics that provide sexually transmitted infections (STIs) testing to performers were offered urogenital, pharyngeal, and rectal chlamydia/gonorrhea testing. Participants were 18 years or older and performed in at least 1 adult film scene within the past year. A Web-based survey was used to collect sexual behavior information. A total of 360 AFPs were enrolled; 75% (n = 271) were women, and the median age was 25 years (interquartile range, 22-31 years). Most reported a main partner (73%), 23% reported non-film transactional partners, and only 6% reported always using condoms on-set. Overall, 24% (n = 86) tested positive for chlamydia or gonorrhea; 15% for chlamydia (n = 54) and 11% for gonorrhea (n = 41). Prevalence of chlamydia/gonorrhea varied by time as a performer (median, year 2 vs year 3; P = 0.06), and days of adult film-work in the past 30 days (median, 6 days vs 4 days; P = 0.02). In multivariable analyses, age (adjusted odds ratio, 0.90; 95% confidence interval, 0.85-0.96) and type of scene (adjusted odds ratio for double vaginal = 2.89; 95% confidence interval, 1.29-6.48) were associated with chlamydia/gonorrhea positivity. Adult film performers had a high prevalence of STIs and reported low levels of condom use in the context of most sexual partnerships. Targeted intervention strategies-both in and outside the workplace-are needed to limit the spread of STIs.

Caregivers of adults with an intellectual disability experience depressive symptoms, but the aging factors of the care recipients associated with the depressive symptoms are unknown. The objective of this study was to analyze the onset aging conditions of adults with an intellectual disability that associated with the depression scores of their primary caregivers. A cross-sectional survey was administered to gather information from 455 caregivers of adults with an intellectual disability about their symptoms of depression which assessed by a 9-item Patient Health Questionnaire (PHQ-9). The 12 aging conditions of adults with an intellectual disability include physical and mental health. The results indicate that 78% of adults with an intellectual disability demonstrate aging conditions. Physical conditions associated with aging include hearing decline (66.3%), vision decline (63.6%), incontinence (44%), articulation and bone degeneration (57.9%), teeth loss (80.4), physical strength decline (81.2%), sense of taste and smell decline (52.8%), and accompanied chronic illnesses (74.6%). Mental conditions associated with aging include memory loss (77%), language ability deterioration (74.4%), poor sleep quality (74.2%), and easy onset of depression and sadness (50.3%). Aging conditions of adults with an intellectual disability (p<0.001) was one factor that significantly affected the presence of depressive symptom among caregivers after controlling demographic characteristics. Particularly, poor sleep quality of adults with an intellectual disability (yes vs. no, OR=3.807, p=0.002) was statistically correlated to the occurrence of significant depressive symptoms among their caregivers. This study suggests that the authorities should reorient community services and future policies toward the needs of family caregivers to decrease the burdens associated with caregiving.

Adult-onset isolated focal dystonia (AOIFD) presenting in early adult life is more frequent in men, whereas in middle age it is female predominant. Temporal discrimination, an endophenotype of adult-onset idiopathic isolated focal dystonia, shows evidence of sexual dimorphism in healthy participants. We assessed the distinctive features of age-related sexual dimorphism of (i) sex ratios in dystonia phenotypes and (ii) sexual dimorphism in temporal discrimination in unaffected relatives of cervical dystonia patients. We performed (i) a meta-regression analysis of the proportion of men in published cohorts of phenotypes of adult-onset dystonia in relation to their mean age of onset and (ii) an analysis of temporal discrimination thresholds in 220 unaffected first-degree relatives (125 women) of cervical dystonia patients. In 53 studies of dystonia phenotypes, the proportion of men showed a highly significant negative association with mean age of onset (p < 0.0001, pseudo-R (2) = 59.6%), with increasing female predominance from 40 years of age. Age of onset and phenotype together explained 92.8% of the variance in proportion of men. Temporal discrimination in relatives under the age of 35 years is faster in women than men but the age-related rate of deterioration in women is twice that of men; after 45 years of age, men have faster temporal discrimination than women. Temporal discrimination in unaffected relatives of cervical dystonia patients and sex ratios in adult-onset dystonia phenotypes show similar patterns of age-related sexual dimorphism. Such age-related sexual dimorphism in temporal discrimination and adult-onset focal dystonia may reflect common underlying mechanisms. Cerebral GABA levels have been reported to show similar age-related sexual dimorphism in healthy participants and may be the mechanism underlying the observed age-related sexual dimorphism in temporal discrimination and the sex ratios in AOIFD.

To establish the morbidity and mortality of patients with univentricular hearts who underwent a repeat median sternotomy at the Instituto Nacional de Pediatría. A retrospective review was performed on the clinical charts of all patients who underwent a repeat median sternotomy from 2001 to 2016. Sixty-five patients underwent 76 surgeries by repeat median sternotomy. Fifty-nine patients had a first repeat median sternotomy, with a mean age of 36 months (range: 4-176 months) and a mean weight of 12.2 kg (range: 3.2-21.5 kg). Forty patients had a Glenn procedure, and 19 patients had a Fontan procedure. There were 17 patients with a second repeat median sternotomy, with a mean age of 89 months (range 48-156 months), and a mean weight of 22.7 kg (14.4-41 kg). A Fontan procedure was performed on all these 17 patients. A section of the right coronary artery with electrocardiographic changes and a right atrium tear that caused hypotension occurred during first repeat sternotomy. An aortic tear occurred during a second repeat sternotomy with massive bleeding and subsequent death. This represents 3.9% of re-entry injuries. It is concluded that repeat median sternotomy is a safe procedure. Copyright © 2016 Instituto Nacional de Cardiología Ignacio Chávez. Publicado por Masson Doyma México S.A. All rights reserved.

Age- and sex-related differences in body composition could affect the pharmacokinetic parameters of administered drugs. The purpose of this post hoc analysis was to investigate the influences of age and sex on the pharmacokinetics of lacosamide. This post hoc analysis used pharmacokinetic data taken at steady state from (i) two phase I studies of oral lacosamide in healthy adult subjects (n = 66), and (ii) a population pharmacokinetic analysis carried out using data from two phase III studies of adjunctive oral lacosamide in adults (n = 565) with focal epilepsy taking 1-3 concomitant anti-epileptic drugs. Phase I data were stratified by age and sex as 'younger female' (aged 18-40 years), 'younger male' (aged 18-45 years) or 'elderly male/female' (aged ≥65 years), then normalized by body weight (lean body weight or fat-free mass), height or volume of distribution, and analysed using non-compartmental analysis. Population pharmacokinetic data were stratified by sex and analysed using a one-compartment model. Minor numerical differences between lacosamide exposure [the area under the concentration-time curve at steady state over the dosage interval (AUCτ,ss)] and the maximum plasma concentration at steady state (C max,ss) in subjects of different ages or sexes were noted. The differences could be explained by a scaling factor between the drug applied and the plasma concentration. Following normalization by lean body weight or volume of distribution, an analysis of relative bioavailability resulted in 90 % confidence intervals of the ratios for AUCτ,ss and C max,ss for age (elderly to younger) or sex (male to female) falling within the range accepted for equivalence (80-125 %); without normalization, the 90 % confidence intervals were outside this range. Minor numerical differences in lacosamide plasma concentrations were noted in the comparison between male and female patients (aged 16-71 years) with focal epilepsy.

This paper describes a novel image filtering method for removal of random-valued impulse noise superimposed on grayscale images. Generally, it is well known that switching-type median filters are effective for impulse noise removal. In this paper, we propose a more sophisticated switching-type impulse noise removal method in terms of detail-preserving performance. Specifically, the noise detector of the proposed method finds out noise-corrupted pixels by focusing attention on the difference between the value of a pixel of interest (POI) and the median of its neighboring pixel values, and on the POI's isolation tendency from the surrounding pixels. Furthermore, the removal of the detected noise is performed by the newly proposed median filter based on non-local processing, which has superior detail-preservation capability compared to the conventional median filter. The effectiveness and the validity of the proposed method are verified by some experiments using natural grayscale images.

The outcomes of adult patients transplanted for Fanconi anaemia (FA) have not been well described. We retrospectively analysed 199 adult patients with FA transplanted between 1991 and 2014. Patients were a median of 16 years of age when diagnosed with FA, and underwent transplantation at a median age of 23 years. Time between diagnosis and transplant was shortest (median 2 years) in those patients who had a human leucocyte antigen identical sibling donor. Fifty four percent of patients had bone marrow (BM) failure at transplantation and 46% had clonal disease (34% myelodysplasia, 12% acute leukaemia). BM was the main stem cell source, the conditioning regimen included cyclophosphamide in 96% of cases and fludarabine in 64%. Engraftment occurred in 82% (95% confidence interval [CI] 76-87%), acute graft-versus-host disease (GvHD) grade II-IV in 22% (95% CI 16-28%) and the incidence of chronic GvHD at 96 months was 26% (95% CI 20-33). Non-relapse mortality at 96 months was 56% with an overall survival of 34%, which improved with more recent transplants. Median follow-up was 58 months. Patients transplanted after 2000 had improved survival (84% at 36 months), using BM from an identical sibling and fludarabine in the conditioning regimen. Factors associated with improved outcome in multivariate analysis were use of fludarabine and an identical sibling or matched non-sibling donor. Main causes of death were infection (37%), GvHD (24%) and organ failure (12%). The presence of clonal disease at transplant did not significant impact on survival. Secondary malignancies were reported in 15 of 131 evaluable patients. © 2017 John Wiley & Sons Ltd.

Adult Age Differences in Dual Information Processes: Implications for the Role of Affective and Deliberative Processes in Older Adults' Decision Making.

2007-03-01

Age differences in affective/experiential and deliberative processes have important theoretical implications for judgment and decision theory and important pragmatic implications for older-adult decision making. Age-related declines in the efficiency of deliberative processes predict poorer-quality decisions as we age. However, age-related adaptive processes, including motivated selectivity in the use of deliberative capacity, an increased focus on emotional goals, and greater experience, predict better or worse decisions for older adults depending on the situation. The aim of the current review is to examine adult age differences in affective and deliberative information processes in order to understand their potential impact on judgments and decisions. We review evidence for the role of these dual processes in judgment and decision making and then review two representative life-span perspectives (based on aging-related changes to cognitive or motivational processes) on the interplay between these processes. We present relevant predictions for older-adult decisions and make note of contradictions and gaps that currently exist in the literature. Finally, we review the sparse evidence about age differences in decision making and how theories and findings regarding dual processes could be applied to decision theory and decision aiding. In particular, we focus on prospect theory (Kahneman & Tversky, 1979) and how prospect theory and theories regarding age differences in information processing can inform one another. © 2007 Association for Psychological Science.

Despite the increasing number of lesbian and gay older adults, research geared towards health and well-being of this population is limited. Many lesbian and gay seniors experience health disparities and are at risk for poor health outcomes. The aims of this study were to gather in-depth information on the concerns of lesbian and gay elders with respect to aging and care needs. The sample included 124 gay men and lesbian women aged 50+ years. Data were gathered via focus groups and questionnaires. The focus groups addressed: (1) concerns about aging in the LGBT community, (2) barriers to needed support and services, (3) concerns about caregiving and (4) needed programs for lesbian and gay seniors. Concerns expressed about aging included: lack of financial security, lack of family or social support, fears about the lack of someone to provide needed care, and discrimination in healthcare or service communities. Participants also indicated concerns about being alone and vulnerable and a need for resources and support programs, specifically for lesbian and gay older adults and for lesbian and gay caregivers. These findings suggest needed areas of support and programs for older gay men and lesbian women. They also suggest that healthcare professionals might need more training regarding the particular needs and concerns of this community.

Recollective experience in odor recognition: influences of adult age and familiarity.

PubMed

Larsson, Maria; Oberg, Christina; Bäckman, Lars

2006-01-01

We examined recollective experience in odor memory as a function of age, intention to learn, and familiarity. Young and older adults studied a set of familiar and unfamiliar odors with incidental or intentional encoding instructions. At recognition, participants indicated whether their response was based on explicit recollection (remembering), a feeling of familiarity (knowing), or guessing. The results indicated no age-related differences in the distribution of experiential responses for unfamiliar odors. By contrast, for familiar odors the young demonstrated more explicit recollection than the older adults, who produced more "know" and "guess" responses. Intention to learn was unrelated to recollective experience. In addition, the observed age differences in "remember" responses for familiar odors were eliminated when odor naming was statistically controlled. This suggests that age-related deficits in activating specific odor knowledge (i.e., odor names) play an important role for age differences in recollective experience of olfactory information.

In the present study, it was proposed to investigate the effects of aging on the strategies used to solve a block design task and to establish whether these strategies may be associated with differential patterns of ability. Two groups of subjects, 30 young adults (aged 20-35 years) and 30 middle-aged adults (aged 45-60 years) were set a computer version of the Kohs task and a battery of tests. An age-related decrease in fluid intelligence (Gf) and visual-spatial ability (Gv) was observed, along with the fact that most of the older subjects used a global strategy rather than a synthetic one. On the other hand, while continuing to use strategies of the analytic type, the older subjects looked more frequently at the model and scored high on crystallized intelligence (Gc). These findings are discussed from two different points of view: the theory of hierarchical stimuli and the hypothesis that metacognitive ability, which is thought to rely on Gc, may increase with age, and thus compensate for the loss of Gf and Gv.

Few prospective cohort studies have examined the association between physical activity (PA) and insomnia prevention, and the effective PA intensity remains unclear. This prospective study explores how PA intensity prevents incident short sleep duration and subjective insufficient sleep in middle-aged and older adults. A self-reported questionnaire gathered data on sleep and PA variables, including moderate low-intensity PA (MLPA); moderate high-intensity PA (MHPA); and vigorous-intensity PA (VPA), during health checkups conducted in Meiji Yasuda Shinjuku Medical Center in Tokyo. This study followed two cohorts from a 2008 baseline survey: (1) participants free of short sleep duration (n=7,061) and (2) participants free of insufficient sleep (n=7,385). They were divided into middle-aged (<60 years; 45.7 [8.8] years for sleep duration and 45.5 [8.8] years for sleep sufficiency) and older adults (both groups aged 65.3 [4.7] years) and followed for a mean 3.4 years until 2013. Data were analyzed in 2014. Engaging in MHPA (hazard ratio [HR]=0.81, 95% CI=0.67, 0.98) and VPA (HR=0.83, 95% CI=0.71, 0.97) had a significant preventive effect on incident subjective insufficient sleep among middle-aged adults. For older adults, only MLPA (HR=0.58, 95% CI=0.42, 0.81) had a significant preventive effect on incident insufficient sleep, and PA did not significantly affect incident short sleep duration. Middle-aged adults engaging in MHPA and VPA and older adults engaging in MLPA can effectively maintain sleep sufficiency. When providing an effective PA program to prevent insomnia, the intensity of PA should correspond to the participant's age. Copyright © 2015 American Journal of Preventive Medicine.

Rowe and Kahn's concept of successful aging remains an important model of well-being; additional research is needed, however, to identify how economically and socially disadvantaged older adults experience well-being, including the role of life events. The findings presented here help address this gap by examining the subjective construction of well-being among urban African American adults (age ≥ 50) with Type 2 diabetes. As part of the National Institute on Aging-funded Subjective Experience of Diabetes among Urban Older Adults study, ethnographers interviewed African American older adults with diabetes (n = 41) using an adaptation of the McGill Illness Narrative Interview. Data were coded using an inductively derived codebook. Codes related to aging, disease prognosis, and "worldview" were thematically analyzed to identify constructions of well-being. Participants evaluate their well-being through comparisons to the past and to the illnesses of friends and family. Diabetes self-care motivates social engagement and care of others. At times, distrust of medical institutions means well-being also is established through nonadherence to suggested biomedical treatment. Hardship and illness in participants' lives frame their diabetes experience and notions of well-being. Providers need to be aware of the social, economic, and political lenses shaping diabetes self-management and subjective well-being. © The Author 2016.

Adult Age Differences in Production and Monitoring in Dual-List Free Recall

PubMed Central

Wahlheim, Christopher N.; Ball, B. Hunter; Richmond, Lauren L.

2017-01-01

The present experiment examined adult age differences in the production and monitoring of responses in dual-list free recall. Younger and older adults studied two lists of unrelated words and were instructed to recall from List 1, List 2, or List 1 and List 2. An externalized free recall (EFR) procedure required participants to: 1) report all responses that came to mind while recalling from specific lists, 2) classify responses as correct or incorrect, and 3) provide confidence judgments for their accuracy classifications. Relative to younger adults, older adults showed a monitoring deficit by misclassifying proportionally more responses and discriminating more poorly between correct and incorrect responses in their confidence judgments. This deficit was especially pronounced under conditions of retroactive interference that occurred when participants recalled from List 1 only. A comparison of retrieval dynamics for all responses produced and for those that participants were reasonably confident were correct provided information about age differences in preretrieval context reinstatement and postretrieval monitoring of retrieved context. One noteworthy finding was that total production when recalling from List 1 showed that List 2 responses remained more accessible across the first several retrieval attempts for older than younger adults, which indicated a substantial age difference in the ability to reinstate List 1 context. Overall, the present findings provide a nuanced characterization of age differences in the operation of production and monitoring mechanisms under conditions of proactive and retroactive interference that can inform models of free recall.

We investigated characteristics of younger and older adults' friendships. Younger (N = 39) and older (N = 39) adults completed measures pertaining to a specific friend they had (i.e., contact frequency, positive friendship quality, and negative friendship quality) and their frequency of problems with friends in general. Older adults reported fewer problems with friends in general, and fewer negative friendship qualities, less frequent contact, and more positive friendship qualities with a specific friend than younger adults. Contact frequency, positive friendship quality, and negative friendship quality with a specific friend were related to frequency of problems with friends in general, but only contact frequency was a significant mediator of the relation between age and frequency of problems with friends in general. Results show that characteristics of a specific friendship relate to problems with friends in general, and that contact frequency with a specific friend mediates the relation between age and problems with friends in general. Implications are discussed. © The Author(s) 2016.

Background. Adult mortality in the first 3 months on antiretroviral therapy (ART) is higher in low-income than in high-income countries, with more similar mortality after 6 months. However, the specific patterns of changing risk and causes of death have rarely been investigated in adults, nor compared with children in low-income countries. Methods. We used flexible parametric hazard models to investigate how mortality risks varied over the first year on ART in human immunodeficiency virus–infected adults (aged 18–73 years) and children (aged 4 months to 15 years) in 2 trials in Zimbabwe and Uganda. Results. One hundred seventy-nine of 3316 (5.4%) adults and 39 of 1199 (3.3%) children died; half of adult/pediatric deaths occurred in the first 3 months. Mortality variation over year 1 was similar; at all CD4 counts/CD4%, mortality risk was greatest between days 30 and 50, declined rapidly to day 180, then declined more slowly. One-year mortality after initiating ART with 0–49, 50–99 or ≥100 CD4 cells/μL was 9.4%, 4.5%, and 2.9%, respectively, in adults, and 10.1%, 4.4%, and 1.3%, respectively, in children aged 4–15 years. Mortality in children aged 4 months to 3 years initiating ART in equivalent CD4% strata was also similar (0%–4%: 9.1%; 5%–9%: 4.5%; ≥10%: 2.8%). Only 10 of 179 (6%) adult deaths and 1 of 39 (3%) child deaths were probably medication-related. The most common cause of death was septicemia/meningitis in adults (20%, median 76 days) and children (36%, median 79 days); pneumonia also commonly caused child deaths (28%, median 41 days). Conclusions. Children ≥4 years and adults with low CD4 values have remarkably similar, and high, mortality risks in the first 3 months after ART initiation in low-income countries, similar to cohorts of untreated individuals. Bacterial infections are a major cause of death in both adults and children; targeted interventions could have important benefits. PMID:22972859

Age is a major prognostic factor in differentiated thyroid cancer (DTC). It is not clear if paediatric DTC has a different histopathological profile and outcome than DTC in adult patients <45 years of age. To assess whether DTC in children and adolescents differs from young age group by comparing paediatric DTC (age ≤ 20) with DTC in patients >20 to <45 years of age. We studied all cases of paediatric DTC seen during the period 1998-2011. We compared this group with a large sample of 213 consecutive adult patients in the age group >20 to <45 years seen during the period 1998-1999 in terms of their pathological features, extent of the disease and long-term outcome. Both groups were managed by the same team at a single institution. A total of 310 DTC were studied including 97 paediatric patients [median age 17 years (range, 8-20)] and 213 young adult patients [median age 33 years (range, 20·5-44·9)]. There was no difference in gender distribution, tumour subtypes, size and tumour multifocality, but there was a significantly higher rate of extrathyroidal extension [40/75 (53·3%) vs 81/213 (38·0%), P = 0·03], lymph node [57/73 (78%) vs 102/183 (55·7%), P < 0·0001] and distant metastases [16/97 (16·5%) vs 8/213 (3·8%), P < 0·0001] in the paediatric than the adult groups. Kaplan-Meier analysis showed a higher risk of persistent/recurrent disease in the paediatric group than adults (log-rank test 0·03). However, there was no mortality secondary to DTC in both groups. Paediatric DTC is distinct from DTC in the young adults (age >20 to <45 years). It is characterized by a higher rate of extrathyroidal extension, lymph node and distant metastases and a higher risk of persistent/recurrent DTC. © 2015 John Wiley & Sons Ltd.

Older adults may evidence changes in swallowing physiology. Our goals were to identify dysphagia risk in community-dwelling older adults with no history of dysphagia, and to compare swallowing physiology and safety between older and younger adults. Thirty-two older adults with no history of dysphagia were prospectively recruited and completed the Dysphagia Handicap Index (DHI), two trials of a 3 oz. swallow screen, and videofluoroscopy (VFSS). Self-ratings of swallowing function were compared to published norms by paired t tests, and multivariate logistic regression models were generated to determine whether these ratings and VFSS analysis of swallowing function were associated with failure of one or both swallow screen trials. Archived VFSS of 33 younger adults were compared to older adults with Wilcoxon rank-sum tests. The DHI scores of older adults were higher than published non-dysphagic adults but lower than dysphagic adults. Older participants with greater Oral Residue scores were more likely to fail both swallow screen trials. Older adults received higher median MBSImP™© scores for select pharyngeal components than younger adults. The two age groups did not differ on Penetration-Aspiration Scale scores, and no aspiration was observed. Measures of swallowing in older individuals may reflect age-related sensory and motor changes in the context of functional swallowing and adequate airway protection.

To assess adolescent and young adult determinants of visceral adipose tissue (VAT) at ages 26-28 years. Prospective study (ages 9-28 years) of cardiometabolic measures, menarche age, menses irregularities, metabolic syndrome, impaired fasting glucose-type 2 diabetes mellitus, and VAT in 400 girls (248 black, 152 white). Adolescent (age 14-19) independent variables for greater VAT at ages 26-28 included larger mean waist circumference (partial R(2) = 30.8%), earlier age at menarche (0.9%), and white race (1.8%). Young adult (ages 20-28 years) independent variables for greater VAT included larger mean waist circumference (partial R(2) = 61.7%), greater triglyceride levels (3.3%), lower high-density lipoprotein cholesterol (1.0%), and greater insulin resistance (homeostasis model assessment-estimated insulin resistance; 0.4%). Independent variables for greater VAT when both adolescent and young adult variables were used included waist (tertile rank change from adolescence to young adulthood, partial R(2) = 58.3%), greater young adult triglyceride levels (4.4%), white race (1.8%), greater young adult homeostasis model assessment-estimated insulin resistance (age 20-28, 2.4%), and earlier menarche age (0.7%). Menses irregularities were not independently associated with young adult VAT. Adolescent girls with early menarche and larger waist circumference should be targets for primary prevention of accretion of VAT. In young adulthood, VAT is associated with dysregulated cardiometabolic profiles, which is greater for those with waist circumference increases from adolescence to adulthood. Waist circumference during young adulthood, and to a lesser degree during adolescence, is an inexpensive surrogate for VAT at ages 26-28 years. Copyright © 2015 Elsevier Inc. All rights reserved.

OBJECTIVE: Urinary iodine concentration is the prime indicator of nutritional iodine status and is used to evaluate population-based iodine supplementation. In 1994, WHO, UNICEF and ICCIDD recommended median urinary iodine concentrations for populations of 100- 200 micro g/l, assuming the 100 micro g/l threshold would limit concentrations <50 micro g/l to adults) and the proportion of concentrations <50 micro g/l. METHOD: A questionnaire on frequency distribution of urinary iodine in iodine-replete populations was circulated to 29 scientific groups. FINDINGS: Nineteen groups reported data from 48 populations with median urinary iodine concentrations >100 micro g/l. The total population was 55 892, including 35 661 (64%) schoolchildren. Median urinary iodine concentrations were 111-540 (median 201) micro g/l for all populations, 100-199 micro g/l in 23 (48%) populations and >/=200 micro g/l in 25 (52%). The frequencies of values <50 micro g/l were 0-20.8 (mean 4.8%) overall and 7.2% and 2.5% in populations with medians of 100-199 micro g/l and >200 micro g/l, respectively. The frequency reached 20% only in two places where iodine had been supplemented for <2 years. CONCLUSION: The frequency of urinary iodine concentrations <50 micro g/l in populations with median urinary iodine concentrations >/=100 micro g/l has been overestimated. The threshold of 100 micro g/l does not need to be increased. In populations, median urinary iodine concentrations of 100-200 micro g/l indicate adequate iodine intake and optimal iodine nutrition.

This article describes the case study on postgraduate students by using descriptive method. A problem is designed to facilitate the reasoning in the topic of Chi-Square test. The problem was given to two male students with different ages to investigate the gesture pattern and it will be related to their reasoning process. The indicators in reasoning problem can obtain the conclusion of analogy and generalization, and arrange the conjectures. This study refers to some questions—whether unique gesture is for every individual or to identify the pattern of the gesture used by the students with different ages. Reasoning problem was employed to collect the data. Two students were asked to collaborate to reason the problem. The discussion process recorded in using video tape to observe the gestures. The video recorded are explained clearly in this writing. Prosodic cues such as time, conversation text, gesture that appears, might help in understanding the gesture. The purpose of this study is to investigate whether different ages influences the maturity in collaboration observed from gesture perspective. The finding of this study shows that age is not a primary factor that influences the gesture in that reasoning process. In this case, adult gesture or gesture performed by order student does not show that he achieves, maintains, and focuses on the problem earlier on. Adult gesture also does not strengthen and expand the meaning if the student’s words or the language used in reasoning is not familiar for younger student. Adult gesture also does not affect cognitive uncertainty in mathematics reasoning. The future research is suggested to take more samples to find the consistency from that statement.

When the mind wanders: age-related differences between young and older adults.

Interest in mind wandering (MW) has grown in recent years, but few studies have assessed this phenomenon in older adults. The aim of this study was to assess age-related differences between young, young-old and old-old adults in MW using two versions of the sustained attention to response task (SART), one perceptual and one semantic. Different indicators were examined (i.e., reported MW episodes and behavioral indices of MW such as response time latency and variability, incorrect response and omission errors). The relationship between MW, certain basic mechanisms of cognition (working memory, inhibition and processing speed), cognitive failures and intrusive thoughts in everyday life was also explored. Findings in both versions of the SART indicated that older adults reported a lower frequency of MW episodes than young adults, but some of the behavioral indices of MW (response time variability, incorrect response and omission errors) were higher in old-old adults. This seems to suggest that MW becomes less frequent with aging, but more pervasive and detrimental to performance. Our results also indicated that the role of age and cognitive mechanisms in explaining MW depends on the demands of the SART task considered. Copyright © 2013 Elsevier B.V. All rights reserved.

This study investigated whether young and older adults vary in their beliefs about the impact of various mitigating factors on age-related memory decline. Eighty young (ages 18-23) and 80 older (ages 60-82) participants reported their beliefs about their own memory abilities and the strategies that they use in their everyday lives to attempt to control their memory. Participants also reported their beliefs about memory change with age for hypothetical target individuals who were described as using (or not using) various means to mitigate memory decline. There were no age differences in personal beliefs about control over current or future memory ability. However, the two age groups differed in the types of strategies they used in their everyday life to control their memory. Young adults were more likely to use internal memory strategies, whereas older adults were more likely to focus on cognitive exercise and maintaining physical health as ways to optimize their memory ability. There were no age differences in rated memory change across the life span in hypothetical individuals. Both young and older adults perceived strategies related to improving physical and cognitive health as effective means of mitigating memory loss with age, whereas internal memory strategies were perceived as less effective means for controlling age-related memory decline.

Aging-Related Geniohyoid Muscle Atrophy Is Related to Aspiration Status in Healthy Older Adults

PubMed Central

2013-01-01

Background. Age-related muscle weakness due to atrophy and fatty infiltration in orofacial muscles may be related to swallowing deficits in older adults. An important component of safe swallowing is the geniohyoid (GH) muscle, which helps elevate and stabilize the hyoid bone, thus protecting the airway. This study aimed to explore whether aging and aspiration in older adults were related to GH muscle atrophy and fatty infiltration. Method. Eighty computed tomography scans of the head and neck from 40 healthy older (average age 78 years) and 40 younger adults (average age 32 years) were analyzed. Twenty aspirators and 20 nonaspirators from the 40 older adults had been identified previously. Two-dimensional views in the sagittal and coronal planes were used to measure the GH cross-sectional area and fatty infiltration. Results. GH cross-sectional area was larger in men than in women (p < .05). Decreased cross-sectional area was associated with aging (p < .05), and cross-sectional area was significantly smaller in aspirators compared with nonaspirators, but only among the older men (p < .01). Increasing fatty infiltration was associated with aging in the middle (p < .05) and posterior (p < .01) portions of the GH muscle. There was no significant difference in fatty infiltration of the GH muscle among aspirators and nonaspirators. Conclusion. GH muscle atrophy was associated with aging and aspiration. Fatty infiltration in the GH muscle was increased with aging but not related to aspiration status. These findings suggest that GH muscle atrophy may be a component of decreased swallowing safety and aspiration in older adults and warrants further investigation. PMID:23112114

Disability affects approximately 15% of the world's population, and has adverse socio-economic effects, especially for the poor. In Rwanda, there are a number of government compensation programs that support the poor, but not specifically persons with disability (PWDs). This study investigates the relationship between poverty and government compensation on disability among working-age adults in Rwanda. This was a secondary analysis of 35,114 adults aged 16 to 65 interviewed in the 2010/2011 Rwanda Household Wealth and Living Conditions survey, a national cross-sectional two-stage cluster survey, stratified by district. This study estimated self-reported major disability, and used chi-square tests to estimate associations (p<0.1) with income, government compensation, occupation type, participation in public works programs, and household poverty status. Non-collinear economic variables were included in a multivariate logistic regression, along with socio-demographic confounders that modified the relationship between any economic predictor and the outcome by 10% or more. All analyses adjusted for sampling weights, stratification, and clustering of households. Over 4% of working-age adults reported having a major disability and the most prevalent types of disability in order were physical, mental, and then sensory disability. In bivariate analysis, annual income, occupation type, and poverty status were associated with major disability (p<0.001 for all). Occupation type was dropped because it was collinear with income. Age, education, and urban/rural residence were confounders. In the multivariate analysis, adults in all income groups had about half the odds of disability compared to adults with no income (Rwf1-120,000 OR = 0.57; Rwf120,000-250,000 OR = 0.61; Rwf250,000-1,000,000 OR = 0.59; Rwf1,000,000+ OR = 0.66; p<0.05 for all), and non-poor adults had 0.77 the odds of disability compared to poor adults (p = 0.001).

Burgess, Sloane; Cimera, Robert E

2014-01-01

The primary purpose of this study was to evaluate the employment outcomes of transition-aged adults with autism spectrum disorders (ASD) served by vocational rehabilitation services (VR) over the last 10 years by state. A secondary purpose was to compare employment outcomes of individuals with ASD to those of the overall transition-aged population served by VR for the same time period. Although there was variability both within and among states, the results of this study indicate that, over time, the number of young adults with ASD seeking VR services has increased; however, employment outcomes including the percent of adults with ASD achieving employment, the number of hours worked, and wages earned have not improved for this group. The cost to provide VR services to transition-aged adults with ASD was relatively stable over time. Transition-aged adults with ASD were more likely to become successfully employed as a result of receiving VR services than the overall population of transition-aged adults served by VR. However, the employed transition-aged adults consistently worked fewer hours and earned lower wages than those in the overall population. Factors that may influence variability within and among states, and between groups, and implications for research and practice are discussed.

Behçet's disease (BD) is one of the reasons of acquired visual impairment among young adults. Ocular involvement is a significant cause of disability in BD. The objective of this study is to assess the prevalence of BD among a group of adults who has visual impairment. Ankara Metropolitan Municipality Education and Technology Center is one of the official institutions which records and follows the demographic data of visually impaired people in Turkey. In November 2014, there were 675 visually impaired people recorded at this center. Medical history was taken from 294 adults by phone in November and December of 2014. Participants were asked if the visual impairment had been either acquired or congenital. If the patients had BD or suspicious BD, they were recalled for detailed investigation which would be carried out by an internist, a rheumatologist and an ophthalmologist. Two hundred thirteen of 294 (72.4%) visually impaired adults were male. One hundred nine of 294 (37.1%) had acquired visual impairment. Six (5.5%) of those 109 patients had BD. Overall prevalence of BD among study group was 2.04%.The median age of people with BD was 35 years. The median age at BD diagnosis was 16.5 years and the median duration from diagnosis to visual loss was 2.5 years. BD is still one of the causes of acquired visual impairment in Turkey. In this study, BD prevalence among a visually impaired adult group was 2.04%. BD accounted for 5.5% among adults who had acquired visual impairment. In a study of 1965, BD prevalence among people with acquired blindness was 12%. However, this study was conducted at pre-immunosuppressive period. Our prevalence is obviously lower than those studies. Extended population-based studies are needed for population estimations.

Heuristics for the inversion median problem

PubMed Central

2010-01-01

Background The study of genome rearrangements has become a mainstay of phylogenetics and comparative genomics. Fundamental in such a study is the median problem: given three genomes find a fourth that minimizes the sum of the evolutionary distances between itself and the given three. Many exact algorithms and heuristics have been developed for the inversion median problem, of which the best known is MGR. Results We present a unifying framework for median heuristics, which enables us to clarify existing strategies and to place them in a partial ordering. Analysis of this framework leads to a new insight: the best strategies continue to refer to the input data rather than reducing the problem to smaller instances. Using this insight, we develop a new heuristic for inversion medians that uses input data to the end of its computation and leverages our previous work with DCJ medians. Finally, we present the results of extensive experimentation showing that our new heuristic outperforms all others in accuracy and, especially, in running time: the heuristic typically returns solutions within 1% of optimal and runs in seconds to minutes even on genomes with 25'000 genes--in contrast, MGR can take days on instances of 200 genes and cannot be used beyond 1'000 genes. Conclusion Finding good rearrangement medians, in particular inversion medians, had long been regarded as the computational bottleneck in whole-genome studies. Our new heuristic for inversion medians, ASM, which dominates all others in our framework, puts that issue to rest by providing near-optimal solutions within seconds to minutes on even the largest genomes.

Adult age differences in unconscious transference: source confusion or identity blending?

PubMed

Perfect, Timothy J; Harris, Lucy J

2003-06-01

Eyewitnesses are known often to falsely identify a familiar but innocent bystander when asked to pick out a perpetrator from a lineup. Such unconscious transference errors have been attributed to either identity confusions at encoding or source retrieval errors. Three experiments contrasted younger and older adults in their susceptibility to such misidentifications. Participants saw photographs of perpetrators, then a series of mug shots of innocent bystanders. A week later, they saw lineups containing bystanders (and others containing perpetrators in Experiment 3) and were asked whether any of the perpetrators were present. When younger faces were used as stimuli (Experiments 1 and 3), older adults showed higher rates of transference errors. When older faces were used as stimuli (Experiments 2 and 3), no such age effects in rates of unconscious transference were apparent. In addition, older adults in Experiment 3 showed an own-age bias effect for correct identification of targets. Unconscious transference errors were found to be due to both source retrieval errors and identity confusions, but age-related increases were found only in the latter.

Motives for adult participation in physical activity: type of activity, age, and gender.

In recent years, there has been a decline in physical activity among adults. Motivation has been shown to be a crucial factor in maintaining physical activity. The purpose of this study was to examine whether motives for participation could accurately discriminate gender, age, and type of physical activity. A quantitative, cross-sectional descriptive research design was employed. The Physical Activity and Leisure Motivation Scale (PALMS) was used to assess motives for physical activity in 1,360 adults (703 males, 657 females) who had been exercising regularly for at least six months. The PALMS consists of 40 items that constitute eight sub-scales (mastery, enjoyment, psychological condition, physical condition, appearance, others' expectations, affiliation, competition/ego). Respondents were divided into two age groups (young adults aged 20 to 40 years and middle-aged adults 41 to 64 years) and five types of activity (individual racing sports plus bowls, team sports, racquet sports, martial arts, and exercise). The group discriminant function analyses revealed significant canonical functions correctly classifying the cases into gender (82%), age group (83%), team sport players 76%, individual racing sport plus bowls players 91%, racquet sport players 90%, exercisers 84%, and martial art players 91%. The competition/ego, appearance, physical condition, and mastery sub-scales contributed most to gender differences. Five sub-scales (mastery, psychological condition, others' expectations, affiliation, and enjoyment) contributed most to the discriminant function for age. For type of activity, different sub-scales were the strongest contributors to the discriminant function for each type of PA. The findings in this study suggest that strong and important motives for participation in physical activity are different across type of activity, age, and gender in adults. Understanding the motives that influence physical activity participation is critical for developing

Overrated adults: 4-year-olds' false belief understanding is influenced by the believer's age.

Seehagen, Sabine; Dreier, Larissa; Zmyj, Norbert

2018-03-01

Children perceive adults as more knowledgeable than peers. We tested whether this general preconception influences preschoolers' performance in a false-belief task. Children (4- and 5-year-olds; N = 146) watched videos showing a peer protagonist or an adult protagonist experiencing events that should lead the protagonist to hold a false belief. Then children were asked to infer the protagonist's perception of the situation. Age of the protagonist influenced 4-year-olds' judgments but not 5-year-olds' judgments. Specifically, 4-year-olds' performance was at chance when presented with a peer protagonist. Their performance dropped further when presented with an adult protagonist and was significantly below chance. Children aged around 5 years performed above chance level regardless of whether they were presented with an adult or peer protagonist. This suggests that in the younger age group, children's tendency to regard adults as experts in general knowledge undermined their ability to accurately judge the possibility that an adult could hold a false belief.

Few studies have investigated differences in age- and gender-specific educational gradients in tobacco smoking among the whole range of adult age groups. We examined educational inequality in smoking among Japanese adults aged 25-94 years. Using a large nationally representative sample (167,925 men and 186,588 women) in 2010, prevalence of current smoking and heavy smoking among daily smokers and their inequalities attributable to educational attainment were analyzed according to sex and age groups. Among men aged 25-34 years, junior high school graduates had the highest current smoking prevalence at 68.4% (95% confidence interval [CI], 66.0%-70.6%), and graduate school graduates had the lowest at 19.4% (95% CI, 17.2%-21.9%). High school graduates had the second highest current smoking prevalence (e.g., 55.9%; 95% CI, 54.9%-56.8% in men aged 25-34 years). Among men aged 75-94 years, the difference in current smoking across educational categories was small. A similar but steeper educational gradient in current smoking was observed among women. Among women aged 25-34 years, junior high school graduates had the highest current smoking prevalence at 49.3% (95% CI, 46.3%-52.3%), and graduate school graduates had the lowest at 4.8% (95% CI, 2.9%-7.4%). Compared with older age groups, such as 65-94 years, younger age groups, such as 25-54 years, had higher estimates of inequality indicators for educational inequality in both current and heavy smoking in both sexes. Educational inequalities in current and heavy smoking were apparent and large in the young population compared with older generations. The current study provides basic data on educational inequalities in smoking among Japanese adults. Copyright © 2016 The Authors. Production and hosting by Elsevier B.V. All rights reserved.

Age Differences in Emotion Regulation Choice: Older Adults Use Distraction Less Than Younger Adults in High-Intensity Positive Contexts.

Previous research demonstrates that younger and older adults prefer distraction over engagement (reappraisal) when regulating high-intensity negative emotion. Older adults also demonstrate a greater bias for positive over negative information in attention and memory compared with younger adults. In this study, we investigated whether emotion regulation choice preferences may differ as a function of stimulus valence with age. The effect of stimulus intensity on negative and positive emotion regulation strategy preferences was investigated in younger and older men. Participants indicated whether they favored distraction or reappraisal to attenuate emotional reactions to negative and positive images that varied in intensity. Men in both age-groups preferred distraction over reappraisal when regulating high-intensity emotion. As no age-related strategic differences were found in negative emotion regulation preferences, older men chose to distract less from high-intensity positive images than did younger men. Older men demonstrated greater engagement with highly positive emotional contexts than did younger men. Thus, age differences in emotion regulation goals when faced with intense emotional stimuli depend on the valence of the emotional stimuli.

The present experiment examined adult age differences in the production and monitoring of responses in dual-list free recall. Younger and older adults studied 2 lists of unrelated words and were instructed to recall from List 1, List 2, or List 1 and List 2. An externalized free recall procedure required participants to: (a) report all responses that came to mind while recalling from specific lists, (b) classify responses as correct or incorrect, and (c) provide confidence judgments for their accuracy classifications. Relative to younger adults, older adults showed a monitoring deficit by misclassifying proportionally more responses and discriminating more poorly between correct and incorrect responses in their confidence judgments. This deficit was especially pronounced under conditions of retroactive interference that occurred when participants recalled from List 1 only. A comparison of retrieval dynamics for all responses produced and for those that participants were reasonably confident were correct provided information about age differences in preretrieval context reinstatement and postretrieval monitoring of retrieved context. One noteworthy finding was that total production when recalling from List 1 showed that List 2 responses remained more accessible across the first several retrieval attempts for older than younger adults, which indicated a substantial age difference in the ability to reinstate List 1 context. Overall, the present findings provide a nuanced characterization of age differences in the operation of production and monitoring mechanisms under conditions of proactive and retroactive interference that can inform models of free recall.

The present study examined leisure activity and its association with caregiver involvement (i.e., residence and time spent with primary caregiver) in 62 middle-aged and older adults with Down syndrome (aged 30-53 years). Findings indicated that middle-aged and older adults with Down syndrome frequently participated in social and passive leisure activities, with low participation in physical and mentally stimulating leisure activities. Residence and time spent with primary caregiver were associated with participation in physical leisure activity. The findings suggest a need for support services aimed at increasing opportunities for participating in physical and mentally stimulating leisure activity by middle-aged and older adults with Down syndrome. These support services should partner with primary caregivers in order to best foster participation in physical leisure activity.

Negative Aging Attitudes Predict Greater Reactivity to Daily Stressors in Older Adults.

Bellingtier, Jennifer A; Neupert, Shevaun D

2016-08-03

In order to understand conflicting findings regarding the emotional reactions of older adults to daily stressors, we examined the possibility that negative aging attitudes could function as an important individual differences factor related to stressor reactivity. Using a daily dairy design, we examined the aging attitudes of 43 older adults reporting on 380 total days. Participants reported their aging attitudes on Day 1, followed by their stressor exposure and negative affect on Days 2-9. Covariates included age, gender, education, and personality. Using multilevel modeling, our results suggest that individuals with more positive aging attitudes report consistent levels of affect across study days regardless of stressors, whereas those with more negative aging attitudes reported increased emotional reactivity to daily stressors. Positive aging attitudes may serve as a resource that helps buffer reactions to daily stressors. © The Author 2016.

Diabetic older adults are at a higher risk of muscle strength (MS) decline than their non-diabetic counterparts. Adequate protein and energy intakes and physical activity (PA) may preserve MS during aging. However, the role of diet quality (DQ) in MS maintenance is still unknown. This study aimed to determine the association between DQ - alone or combined with PA - and changes in MS over 3 years in diabetic participants aged 67 to 84 years at recruitment in a secondary analysis of the longitudinal observational NuAge study. Changes in handgrip, knee extensor and elbow flexor strengths were calculated as the difference between recruitment (T1) and after 3 years (T4) in 156 diabetic older adults. Baseline DQ was calculated from 3 non-consecutive 24-hour dietary recalls collected at T1 using the validated Canadian Healthy Eating Index (C-HEI). Change in PA was calculated from Physical Activity Scale for the Elderly (PASE) as PASE T4-PASE T1. Four combinations of variables were created: C-HEI<70 with PASE change either < or > median and C-HEI ≥ 70 with PASE change either < or > median. The association between these four categories and MS maintenance was evaluated using General Linear Modeling (GLM). Analyses were stratified by sex and controlled for covariates. Baseline DQ alone was not associated with MS maintenance. Baseline DQ combined with PASE change showed associations with crude and baseline adjusted handgrip strength (p=0.031, p=0.018) and crude and baseline adjusted elbow flexor change (p=0.028, p=0.017) in males only; no significant results were found for knee extensor strength in either males or females. While findings for females were inconclusive, results demonstrate that better adherence to dietary guidelines combined with a more active lifestyle may prevent MS decline among diabetic older males. Additional research is needed on a larger sample since generalization of these results is limited by the small sample size. Copyright © 2013 Elsevier Inc. All

Movie smoking and urge to smoke among adult smokers.

Few studies have assessed the association between exposure to movie smoking and urge to smoke under real-world conditions. We conducted exit interviews with 4,073 movie patrons, of whom 2,817 were aged 18 years or older. Some 536 were smokers and had complete data. Subjects had exited 26 movies, of which 12 contained smoking. We used least squares regression to assess the association between exposure to movie smoking and urge to smoke (scale range 0-10), controlling for movie rating, age, sex, heaviness of smoking index (HSI, range 0-6), and time since last cigarette smoked. Median age was 27 years and 52% were female. Median urge to smoke level at movie exit was 7. The dose-response between higher categories of movie smoking and median urge to smoke was one point for two lower categories (1-11 and 11-54 s) and two for the highest category (>or=55 s), but these differences were not statistically significant. In the multivariate analysis, attendance of a movie with smoking was associated with a 0.81-point increase (95% CI = 0.46-1.16) in urge to smoke. For comparison, an HSI score of 3 (vs. 0) was associated with a 2-point increase in urge to smoke. In this sample of adult smokers, exposure to movie smoking was associated with higher urge to smoke after the movie, independent of movie rating. The effect size was consistent with responses seen in cue reactivity experiments. Exposure to movie smoking may affect urge to smoke among adult smokers.

Aging in movement representations for sequential finger movements: a comparison between young-, middle-aged, and older adults.

Studies show that as we enter older adulthood (>64years), our ability to mentally represent action in the form of using motor imagery declines. Using a chronometry paradigm to compare the movement duration of imagined and executed movements, we tested young-, middle-aged, and older adults on their ability to perform sequential finger (fine-motor) movements. The task required number recognition and ordering and was presented in three levels of complexity. Results for movement duration indicated no differences between young- and middle-aged adults, however both performed faster than the older group. In regard to the association between imagined and executed actions, correlation analyses indicated that values for all groups were positive and moderate (r's .80,.76,.70). In summary, whereas the older adults were significantly slower in processing actions than their younger counterparts, the ability to mentally represent their actions was similar.

Measuring malnutrition in hospitalized patients is difficult in all settings. I evaluated associations of items in the mini nutritional assessment short-form (MNA-sf), a nutritional-risk screening tool previously validated in the elderly, with malnutrition among hospitalized patients in Uganda. I used results to construct two simplifications of this tool that may be applicable to young and middle-aged adults. I assessed the association of each MNA-sf item with the mid-upper arm circumference (MUAC), a specific measure of malnutrition at appropriate cut-offs. I incorporated only malnutrition-specific items into the proposed simplifications scoring each item according to its association with malnutrition. I assessed numbers classified to different score-levels by the simplifications and, via proportional hazards regression, how the simplifications predicted in-hospital mortality. I analyzed 318 patients (median age 37, interquartile range 27 to 56). Variables making it into the simplifications were: reduced food intake, weight loss, mobility, and either BMI in kg/m(2) (categorized as <16, 16 to 16.9, and ≥17) or MUAC in centimeters (categorized as <16 or <17, 16 to 18.9 or 17 to 19.9, and ≥19 or ≥20 for females and males respectively). Compared to the traditional MNA-sf, the simplifications classified fewer patients as malnourished, yet remained strongly predictive of in-hospital mortality. In the MUAC-incorporating simplification, malnourished patients had 3.8-fold (95% CI 1.9 to 7.8) higher risk of in-hospital death than those not malnourished; adjusting for age, sex, and HIV status. The MNA-sf simplifications described may provide an improved measure of malnutrition in hospitalized young and middle-aged adults. Copyright © 2016 Elsevier Inc. All rights reserved.

To investigate the utilization of health care services before and after transfer from pediatric to adult rheumatology care in clinical practice. Using US commercial claims data from January 2005 through August 2012, we identified individuals with a JIA diagnosis code from a pediatric rheumatologist followed by any diagnosis code from an adult rheumatologist. Individuals had 6 months observable time before the last pediatric visit and 6 months after the first adult visit. Medication, emergency room, physical therapy use, and diagnosis codes were compared between the pediatric and adult interval using McNemar's test. The proportion of days covered (PDC) of TNFi for the time between last pediatric and first adult visit was calculated. We identified 58 individuals with JIA who transferred from pediatric to adult rheumatology care after the age of 14. The median age at the last pediatric rheumatology visit was 18.1 years old and the median transfer interval was 195 days. 29 % of patients received NSAIDs in the adult interval compared to 43 % in the pediatric interval (p = 0.06). In the pediatric interval, 71 % received a JRA and 0 % received an RA physician diagnosis code compared to 28 and 45 %, respectively, in the adult interval. The median PDC for patients receiving a TNFi was 0.75 during the transfer interval. Individuals with JIA who transferred to adult care were more likely receive a diagnosis of RA instead of JRA and were less likely to receive NSAIDs, but had no significant immediate changes to other medication use.

There is a rapidly growing group of aging adults with autism spectrum disorder (ASD) who may have unique needs, yet cognitive and brain function in older adults with ASD is understudied. We combined functional and structural neuroimaging and neuropsychological tests to examine differences between middle-aged men with ASD and matched neurotypical (NT) men. Participants (ASD, n = 16; NT, n = 17) aged 40-64 years were well-matched according to age, IQ (range: 83-131), and education (range: 9-20 years). Middle-age adults with ASD made more errors on an executive function task (Wisconsin Card Sorting Test) but performed similarly to NT adults on tests of delayed verbal memory (Rey Auditory Verbal Learning Test) and local visual search (Embedded Figures Task). Independent component analysis of a functional MRI working memory task (n-back) completed by most participants (ASD = 14, NT = 17) showed decreased engagement of a cortico-striatal-thalamic-cortical neural network in older adults with ASD. Structurally, older adults with ASD had reduced bilateral hippocampal volumes, as measured by FreeSurfer. Findings expand our understanding of ASD as a lifelong condition with persistent cognitive and functional and structural brain differences evident at middle-age. Autism Res 2017, 10: 1945-1959. © 2017 International Society for Autism Research, Wiley Periodicals, Inc. We compared cognitive abilities and brain measures between 16 middle-age men with high-functioning autism spectrum disorder (ASD) and 17 typical middle-age men to better understand how aging affects an older group of adults with ASD. Men with ASD made more errors on a test involving flexible thinking, had less activity in a flexible thinking brain network, and had smaller volume of a brain structure related to memory than typical men. We will follow these older adults over time to determine if aging changes are greater for individuals with ASD. © 2017 International Society for Autism Research

Forever young: Visual representations of gender and age in online dating sites for older adults.

Online dating has become increasingly popular among older adults following broader social media adoption patterns. The current study examined the visual representations of people on 39 dating sites intended for the older population, with a particular focus on the visualization of the intersection between age and gender. All 39 dating sites for older adults were located through the Google search engine. Visual thematic analysis was performed with reference to general, non-age-related signs (e.g., facial expression, skin color), signs of aging (e.g., perceived age, wrinkles), relational features (e.g., proximity between individuals), and additional features such as number of people presented. The visual analysis in the present study revealed a clear intersection between ageism and sexism in the presentation of older adults. The majority of men and women were smiling and had a fair complexion, with light eye color and perceived age of younger than 60. Older women were presented as younger and wore more cosmetics as compared with older men. The present study stresses the social regulation of sexuality, as only heterosexual couples were presented. The narrow representation of older adults and the anti-aging messages portrayed in the pictures convey that love, intimacy, and sexual activity are for older adults who are "forever young."

Background The aim of this research was to compare associations of self-perceived successful aging (SPSA) among Young-Old (Y-O; age 50–74 years) versus Old-Old (O-O; 75–99 years) community-dwelling adults. To our knowledge, this is the first study to compare respondents’ self-perceptions of successful aging among O-O relative to Y-O adults. Methods Participants included 365 Y-O and 641 O-O adults. The two age groups were compared in terms of the association of SPSA with other preselected measures including sociodemographic information, physical and mental functioning, objective and subjective cognitive functioning, emotional health, and positive psychological constructs. Results The O-O group reported higher levels of SPSA than the Y-O group. In multiple regression modeling examining predictors of SPSA in each group, there was a tendency toward lower associations in the O-O group overall. Most notably, the associations between physical and mental functioning with SPSA were significantly lower in the O-O versus Y-O group. There were no associations with SPSA that were significantly higher in the O-O versus Y-O group. Conclusion The lower predictive power of physical and mental functioning on SPSA among O-O relative to Y-O adults is particularly noteworthy. It is apparent that SPSA is a multidimensional construct that cannot be defined by physical functioning alone. Continuing to clarify the underlying factors impacting SPSA between groups may inform tailored interventions to promote successful aging in Y-O and O-O adults. PMID:25369763

Greater Perceived Similarity between Self and Own-Age Others in Older than Young Adults

As people age, they increasingly incorporate age-stereotypes into their self-view. Based on this evidence we propose that older compared to young adults identify to a greater extent with their own-age group on personality traits, an effect that may be particularly pronounced for positive traits. Two studies tested these hypotheses by examining associations in young and older adults between evaluations of self and own-age others on personality traits that varied on valence. In both studies, young and older participants rated personality trait adjectives on age typicality, valence, and self typicality. Converging results across both studies showed that older compared to young participants were more likely to endorse personality traits as self-typical when those traits were also perceived as more typical for their own-age group, independent of whether age was made salient to participants prior to evaluation. In addition, there was evidence that the association between evaluations of self and own-age others in older participants was greater for more positive personality traits. This age-differential pattern is discussed in the context of increased age salience in aging and its effect on the similarity between evaluations of self and own-age others in older compared to young adults.

This study integrates healthy ageing and health psychology theories to explore the mechanisms underlying the relationship between health control expectancies and age-attitudes on the process of ageing well. Specifically, the aim of this study is to investigate the relationship between age-stereotypes and health locus of control. A population-based survey of 739 adults aged 20-97 years (mean = 57.3 years, SD = 13.66; 42% female) explored attitudes towards ageing and health attitudes. A path-analytical approach was used to investigate moderating effects of age and gender. Higher age-stereotype endorsement was associated with higher chance (β = 2.91, p < .001) and powerful other (β = 1.07, p = .012) health expectancies, after controlling for age, gender, education and self-rated health. Significant age and gender interactions were found to influence the relationship between age-stereotypes and internal health locus of control. Our findings suggest that the relationship between age-stereotypes and health locus of control dimensions must be considered within the context of age and gender. The findings point to the importance of targeting health promotion and interventions through addressing negative age-attitudes.

We determine whether age is a prognostic factor for surgical outcomes of external dacryocystorhinostomy (Ex-DCR). This retrospective cohort study conducted at Tilganga Institute of Ophthalmology (Kathmandu, Nepal) compared pediatric Ex-DCR procedures (age ≤ 15 years) to adult Ex-DCR procedures (age > 15 years) and was performed between January 2013 and December 2013, with a minimum follow-up period of 6 months. Primary outcome measure was rate of success, defined as complete resolution of subjective symptom(s) of epiphora (subjective success), combined with patent lacrimal passage on syringing (anatomical success) at last follow-up visit. Other outcome measures included clinical presentation, diagnosis, intraoperative complications and post-operative complications. In total, 154 Ex-DCR procedures were included, with an age range of 8 months to 81 years (mean age 36.4 ± 21.0 years). In all, 38 pediatric Ex-DCR procedures were compared to 116 adult procedures. Success rates were 97% in the pediatric group and 95% in the adult group, with no clinically or statistically significant difference in success rate or complication rate between groups (p > 0.05). Our study yielded high success rates of Ex-DCR in both pediatric and adult age groups suggesting that Ex-DCR remains an optimal treatment choice for all age groups. With no difference in surgical outcomes between pediatric and adult patients, including complication rate, we conclude that age is not a prognostic factor for Ex-DCR failure. We do not recommend adjuvant therapy for pediatric patients.

Pediatric Cystic Nephroma Is Morphologically, Immunohistochemically, and Genetically Distinct From Adult Cystic Nephroma.

The term cystic nephroma has traditionally been used to refer to 2 neoplasms, a lesion in adults that is now thought to be part of the spectrum of mixed epithelial stromal tumor (MEST) and a pediatric lesion that has been associated with mutations in the DICER1 gene. A direct detailed morphologic, immunohistochemical, and genetic comparison of these 2 lesions has not been performed. In this study, we compare the morphologic features, immunoreactivity for estrogen receptor and inhibin, and DICER1 genetic status of 12 adult cystic nephroma/MEST (median age 50.5 y, all females) and 7 pediatric cystic nephroma (median age 1.3 y, male:female=6:1). Both lesions (11 of 12 adult cases, 6 of 7 pediatric cases) frequently demonstrated subepithelial accentuation of stromal cellularity, though the increased cellularity frequently included inflammatory cells in the pediatric cases. All adult and pediatric cases labeled for estrogen receptor; however, whereas most (83%) of adult cases labeled for inhibin at least focally, no pediatric case labeled for inhibin. Most adult cases (58%) demonstrated wavy, ropy collagen in association with cellular stroma, whereas this was not found in pediatric cases. 86% of pediatric cases demonstrated DICER1 mutations, whereas only 1 of 10 adult cases demonstrated a DICER1 mutation. In summary, although cellular stroma and estrogen receptor immunoreactivity are commonly present in both adult and pediatric cystic nephroma, ropy collagen and inhibin immunoreactivity are far more common in adult cystic nephroma/MEST, whereas DICER1 mutations are far more prevalent in pediatric cystic nephroma. These results support the current World Health Organization Classification's separation of adult and pediatric cystic nephromas as distinct entities.

Age-Specific Patient Navigation Preferences Among Adolescents and Young Adults with Cancer.

Patient navigation is increasingly being directed at adolescent and young adult (AYA) patients. This study provides a novel description of differences in AYA cancer patients' preferences for navigation services by developmental age at diagnosis. Eligible patients were diagnosed with cancer between ages 15 and 39 and had completed at least 1 month of treatment. Between October 2015 and January 2016, patients completed semi-structured interviews about navigation preferences. Summary statistics of demographic and cancer characteristics were generated. Differences in patient navigation preferences were examined through qualitative analyses by developmental age at diagnosis. AYAs were interviewed (adolescents 15-18 years N = 8; emerging adults 19-25 years N = 8; young adults 26-39 years N = 23). On average, participants were 4.5 years from diagnosis. All age groups were interested in face-to-face connection with a navigator and using multiple communication platforms (phone, text, email) to follow-up. Three of the most frequently cited needs were insurance, finances, and information. AYAs differed in support, healthcare, and resource preferences by developmental age; only adolescents preferred educational support. While all groups preferred financial and family support, the specific type of assistance (medical versus living expenses, partner/spouse, child, or parental assistance) varied by age group. AYAs with cancer have different preferences for patient navigation by developmental age at diagnosis. AYAs are not a one-size-fits-all population, and navigation programs can better assist AYAs when services are targeted to appropriate developmental ages. Future research should examine fertility and navigation preferences by time since diagnosis. While some navigation needs to span the AYA age range, other needs are specific to developmental age.

Collaborative remembering in older adults: age-invariant outcomes in the context of episodic recall deficits.

PubMed

Henkel, Linda A; Rajaram, Suparna

2011-09-01

Rapidly growing research reveals complex yet systematic consequences of collaboration on memory in young adults, but much less is known about this phenomenon in older adults. Young and older adults studied a list of categorized words and took three successive recall tests. Test 1 and 3 were always taken individually, and Test 2 was done either in triads or alone. Despite older adults recalling less overall than young adults, both age groups exhibited similar costs and benefits of collaboration: Collaboration reduced both correct and false recall during collaborative remembering, was associated with more positive beliefs about its value, and produced reminiscence, collective memory, and some forgetting in its cascading effects on postcollaborative recall. We examine the role of retrieval organization in these effects. As environmental support may play a substantial role in healthy aging, the relatively preserved effects of collaboration on memory in older adults hold promise for testing judicious uses of group remembering in aging.

[Metacarpophalangeal and carpal numeric indices to calculate bone age and predict adult size].

PubMed

Ebrí Torné, B; Ebrí Verde, I

2012-04-01

This work presents new numerical methods from the meta-carpal-phalangeal and carpal indexes, for calculating bone age. In addition, these new methods enable the adult height to be predicted using multiple regression equations. The longitudinal case series studied included 160 healthy children from Zaragoza, of both genders, aged between 6 months and 20 years, and studied annually, including the radiological study. For the statistical analysis the statistical package "Statistix", as well as the Excel program, was used. The new indexes are closely co-related to the chronological age, thus leading to predictive equations for the calculation of the bone age of children up to 20 years of age. In addition, it presents particular equations for up to 4 years of age, in order to optimise the diagnosis at these early ages. The resulting bones ages can be applied to numerical standard deviation tables, as well as to an equivalences chart, which directly gives us the ossification diagnosis. The predictive equations of adult height allow a reliable forecast of the future height of the studied child. These forecasts, analysed by the Student test did not show significant differences as regards the adult height that children of the case series finally achieved. The results can be obtained with a pocket calculator or through free software available for the reader. For the first time, and using a centre-developed and non-foreign methods, bones age standards and adult height predictive equations for the study of children, are presented. We invite the practitioner to use these meta-carpal-phalangeal and carpal methods in order to achieve the necessary experience to apply it to a healthy population and those with different disorders.

Age-related differences in cognition across the adult lifespan in autism spectrum disorder.

PubMed

Lever, Anne G; Geurts, Hilde M

2016-06-01

It is largely unknown how age impacts cognition in autism spectrum disorder (ASD). We investigated whether age-related cognitive differences are similar, reduced or increased across the adult lifespan, examined cognitive strengths and weaknesses, and explored whether objective test performance is related to subjective cognitive challenges. Neuropsychological tests assessing visual and verbal memory, generativity, and theory of mind (ToM), and a self-report measure assessing cognitive failures were administered to 236 matched participants with and without ASD, aged 20-79 years (IQ > 80). Group comparisons revealed that individuals with ASD had higher scores on visual memory, lower scores on generativity and ToM, and similar performance on verbal memory. However, ToM impairments were no longer present in older (50+ years) adults with ASD. Across adulthood, individuals with ASD demonstrated similar age-related effects on verbal memory, generativity, and ToM, while age-related differences were reduced on visual memory. Although adults with ASD reported many cognitive failures, those were not associated with neuropsychological test performance. Hence, while some cognitive abilities (visual and verbal memory) and difficulties (generativity and semantic memory) persist across adulthood in ASD, others become less apparent in old age (ToM). Age-related differences characteristic of typical aging are reduced or parallel, but not increased in individuals with ASD, suggesting that ASD may partially protect against an age-related decrease in cognitive functioning. Despite these findings, adults with ASD experience many cognitive daily challenges, which highlights the need for adequate social support and the importance of further research into this topic, including longitudinal studies.

Hippocampal neurogenesis undergoes dramatic age-related changes. Mice with targeted deletion of the clock geneBmal1 (Bmal1(-/-)) show disrupted regulation of reactive oxygen species homeostasis, accelerated aging, neurodegeneration and cognitive deficits. As proliferation of neuronal progenitor/precursor cells (NPCs) is enhanced in young Bmal1(-/-) mice, we tested the hypothesis that this results in premature aging of hippocampal neurogenic niche in adult Bmal1(-/-) mice as compared to wildtype littermates. We found significantly reduced pool of hippocampal NPCs, scattered distribution, enhanced survival of NPCs and an increased differentiation of NPCs into the astroglial lineage at the expense of the neuronal lineage. Immunoreaction of the redox sensitive histone deacetylase Sirtuine 1, peroxisomal membrane protein at 70 kDa and expression of the cell cycle inhibitor p21(Waf1/CIP1) were increased in adult Bmal1(-/-) mice. In conclusion, genetic disruption of the molecular clockwork leads to accelerated age-dependent decline in adult neurogenesis presumably as a consequence of oxidative stress.

The present study examined leisure activity and its association with caregiver involvement (i.e., residence and time spent with primary caregiver) in 62 middle-aged and older adults with Down syndrome (aged 30–53 years). Findings indicated that middle-aged and older adults with Down syndrome frequently participated in social and passive leisure activities, with low participation in physical and mentally stimulating leisure activities. Residence and time spent with primary caregiver were associated with participation in physical leisure activity. The findings suggest a need for support services aimed at increasing opportunities for participating in physical and mentally stimulating leisure activity by middle-aged and older adults with Down syndrome. These support services should partner with primary caregivers in order to best foster participation in physical leisure activity. PMID:28375797

Eating disorders (EDs) present across a broad age range, yet little is known about the characteristics and outcome of midlife patients compared to younger patients. Among patients seeking ED treatment who were stratified by age at initial assessment (IA), this study aimed to (1) discern sociodemographic and clinical differences, (2) determine outcome rates, and (3) identify predictors of poor outcome including death. Participants [219 females (12 years or older, 94.1% Caucasian) who completed outcome assessment and 31 known decedents] were stratified by age at IA (<18 as youth, 18-39 as young adult, and ≥40 years as midlife adult). Analyses of variance and chi-square tests identified group differences; ordered logistic regression with stepwise selection identified factors predicting outcome. Midlife adults were more significantly compromised at follow-up compared to youths and young adults, including psychological and physical quality of life, ineffectiveness, interpersonal concerns, and general psychological maladjustment. Midlife adults had the highest rates of poor outcome or death; good outcome was achieved by only 5.9% of midlife adult compared to 14.0% of young adult and 27.5% of youth patients. Older age at IA, alcohol and/or drug misuse, endocrine concerns, and absence of family ED history predicted poor outcome or death. Midlife adults seeking ED treatment have more complex medical and psychological concerns and poorer outcomes than youths and young adults; further exploration is needed to improve treatment outcome. Specialized treatment focusing on quality of life, comorbid medical concerns, interpersonal connection, and emotion regulation is encouraged. © 2014 Wiley Periodicals, Inc.

The capacity of visual-spatial working memory (WM) declines from early to late adulthood. Recent attempts at identifying neural correlates of WM capacity decline have focused on the maintenance phase of WM. Here, we investigate neural mechanisms during the encoding phase as another potential mechanism contributing to adult age differences in WM capacity. We used electroencephalography to track neural activity during encoding and maintenance on a millisecond timescale in 35 younger and 35 older adults performing a visual-spatial WM task. As predicted, we observed pronounced age differences in ERP indicators of WM encoding: Younger adults showed attentional selection during item encoding (N2pc component), but this selection mechanism was greatly attenuated in older adults. Conversely, older adults showed more pronounced signs of early perceptual stimulus processing (N1 component) than younger adults. The amplitude modulation of the N1 component predicted WM capacity in older adults, whereas the attentional amplitude modulation of the N2pc component predicted WM capacity in younger adults. Our findings suggest that adult age differences in mechanisms of WM encoding contribute to adult age differences in limits of visual-spatial WM capacity. Copyright © 2013 Elsevier Inc.

To describe demographic, therapeutic and follow-up data of four cases of renal cell carcinoma with Xp11.2 translocation in adults older than 50 years of age. Between January 2008 and December 2011, 170 patients underwent surgery for renal cell carcinoma in our center. Systematic histopathologic analysis of specimen removed was performed. Complementary immunohistochemical analysis was performed only in cases with uncertain diagnosis or in patients younger than 40 years of age. Among these 170 patients with a median age of 59years old (21-89), immunohistochemistry helped find a TFE3 translocation in four cases (2.4%). There were three women and one man of 53, 71, 75 and 86years old respectively. One patient was metastatic at diagnosis. Radical nephrectomy was first performed in all cases. TNM staging was T3aN2R0, T3bN0R0, T2N2R0 and T3aN2R2, with a Furhman grade of 4. Two patients progressed with metastasis 5 and 7months after surgery, and two with lymphatic invasion 2 and 9months after nephrectomy. One patient died during follow-up. Xp11.2 translocation renal cell carcinoma was uncommon after 50years of age in our series, but probably under estimated. It seemed to be associated with a poor prognosis. Larger studies must be performed to optimize its specific treatment. Copyright © 2012 Elsevier Masson SAS. All rights reserved.

Study Objectives: Sleep duration has been associated with risk of dementia and stroke, but few studies have investigated the relationship between sleep duration and brain MRI measures, particularly in middle age. Methods: In a prospective cohort of 613 black and white adults (mean age = 45.4 years) enrolled in the Coronary Artery Risk Development in Young Adults (CARDIA) study, participants reported typical sleep duration, dichotomized into moderate sleep duration (> 6 to ≤ 8 h) and short sleep duration (≤ 6 h) at baseline (2005–2006). Five years later, we obtained brain MRI markers of white matter including fractional anisotropy, mean diffusivity, and white matter hyperintensities. Results: Compared to moderate sleepers, short sleepers had an elevated ratio of white matter hyperintensities to normal tissue in the parietal region (OR = 2.31, 95% CI: 1.47, 3.61) adjusted for age, race/sex, education, hypertension, stroke/TIA, depression, smoking status, and physical activity. White matter diffusivity was also higher, approximately a 0.2 standard deviation difference, in frontal, parietal, and temporal white matter regions, among those reporting shorter sleep duration in (P < 0.05 for all). Conclusions: Short sleep duration was associated with worse markers of white matter integrity in midlife. These mid-life differences in white matter may underlie the link between poor sleep and risk of dementia and stroke.

Ghetti, Simona; Qin, Jianjian; Goodman, Gail S

2002-09-01

This study investigated developmental trends associated with the Deese/Roediger-McDermott false-memory effect, the role of distinctive information in false-memory formation, and participants' subjective experience of true and false memories. Children (5- and 7-year-olds) and adults studied lists of semantically associated words. Half of the participants studied words alone, and half studied words accompanied by pictures. There were significant age differences in recall (5-year-olds evinced more false memories than did adults) but not in recognition of critical lures. Distinctive information reduced false memory for all age groups. Younger children provided with distinctive information, and older children and adults regardless of whether they viewed distinctive information, expressed higher levels of confidence in true than in false memories. Source attributions did not significantly differ between true and false memories. Implications for theories of false memory and memory development are discussed.

2011-01-01

The purpose of this study was to examine the effect of participation in a music-based intergenerational music program on cross-age interactions and cross-age attitudes of elementary-age children and older adults, and older adults' psychosocial well-being. Twenty-one children in the 4th grade volunteered to participate in the experimental (n = 12) or control (n = 9) group. Twenty-six older adults from a retirement living facility also volunteered to participate in the experimental (n = 14) or control (n = 12) group. Ten 30-min music sessions occurred in which participants engaged in singing, structured conversation, moving to music, and instrument playing interventions. Data analysis of cross-age interactions revealed that the interventions "structured conversation" and "moving to music" were more effective in eliciting interaction behaviors than the interventions "singing" and "instrument playing." Standardized measures revealed that children's attitudes towards older adults improved, though not significantly so, after participation in the intergenerational program. Results of biweekly post-session questionnaires revealed a decrease in negative descriptions of older adults and an increase in positive descriptions of older adults--suggesting a more positive view towards aging. Results revealed that older adults' attitudes towards children improved significantly after their participation in the intergenerational program. While standardized measures revealed that older adults did not perceive a significant improvement in their psychosocial well-being, their bi-weekly post-session questionnaires showed they perceived increased feelings of usefulness and other personal benefits from the intergenerational interactions. Suggestions for future research, the utility of varied measurement instruments, and implications for practice are discussed.

Adults with cerebral palsy (CP) experience multiple, functional changes as they age, including changes to communication modes and methods that enable development and maintenance of relationships, communicative participation and quality-of-life. Little is known about the nature of communication changes experienced by this group. The aim of this study was to better understand how adults with CP experience changes in their communication abilities as they age and the subsequent psychosocial impact. Twenty adults with cerebral palsy aged 40-72 years with complex communication needs (CCN) participated in a series of in-depth interviews, framing their experiences of loss and grief throughout their lives. The impact of changing communication abilities emerged as an important area of focus. Data were analysed using constructivist grounded theory methodology. Themes arising from the participants' perceptions of their communication included experiencing communication change as a loss with subsequent impact on self-concept; and how communication is integral to the process of managing losses associated with older age. Implications for speech-language pathologists working with older people with cerebral palsy and CCN include the need to understand the psychosocial impact of communication changes on social interaction, relationships and communicative participation. It is important to promote positive and meaningful communication options that maintain a coherent sense of self in addition to promoting functional communication skills and communicative participation.

Adaptive marginal median filter for colour images.

PubMed

Morillas, Samuel; Gregori, Valentín; Sapena, Almanzor

2011-01-01

This paper describes a new filter for impulse noise reduction in colour images which is aimed at improving the noise reduction capability of the classical vector median filter. The filter is inspired by the application of a vector marginal median filtering process over a selected group of pixels in each filtering window. This selection, which is based on the vector median, along with the application of the marginal median operation constitutes an adaptive process that leads to a more robust filter design. Also, the proposed method is able to process colour images without introducing colour artifacts. Experimental results show that the images filtered with the proposed method contain less noisy pixels than those obtained through the vector median filter.

Millennials (ages 18-35) are now the largest living generation in the US, making it important to understand and characterize the rising trend of colorectal cancer incidence in this population, as well as other younger generations of Americans. Data from the New Jersey State Cancer Registry (n = 181 909) and Surveillance, Epidemiology, and End Results program (n = 448 714) were used to analyze invasive CRC incidence trends from 1979 to 2014. Age, sex, race, ethnicity, subsite, and stage differences between younger adults (20-49) and screening age adults (≥50) in New Jersey (NJ) were examined using chi-square; and, we compared secular trends in NJ to the United States (US). Whites, men, and the youngest adults (ages 20-39) are experiencing greater APCs in rectal cancer incidence. Rates among younger black adults, overall, were consistently higher in both NJ and the US over time. When compared to older adults, younger adults with CRC in NJ were more likely to be: diagnosed at the late stage, diagnosed with rectal cancer, male, non-white, and Hispanic. Invasive CRC incidence trends among younger adults were found to vary by age, sex, race, ethnicity, and subsite. Large, case-level, studies are needed to understand the role of genetics, human papillomavirus (HPV), and cultural and behavioral factors in the rise of CRC among younger adults. Provider and public education about CRC risk factors will also be important for preventing and reversing the increasing CRC trend in younger adults. © 2018 The Authors.

Homeostatic regulation of adult hippocampal neurogenesis in aging rats: long-term effects of early exercise

Adult neurogenesis is highly responsive to environmental and physiological factors. The majority of studies to date have examined short-term consequences of enhancing or blocking neurogenesis but long-term changes remain less well understood. Current evidence for age-related declines in neurogenesis warrant further investigation into these long-term changes. In this report we address the hypothesis that early life experience, such as a period of voluntary running in juvenile rats, can alter properties of adult neurogenesis for the remainder of the animal's life. The results indicate that the number of proliferating and differentiating neuronal precursors is not altered in runners beyond the initial weeks post-running, suggesting homeostatic regulation of these processes. However, the rate of neuronal maturation and survival during a 4 week period after cell division was enhanced up to 11 months of age (the end of the study period). This study is the first to show that a transient period of physical activity at a young age promotes changes in neurogenesis that persist over the long-term, which is important for our understanding of the modulation of neurogenesis by exercise with age. Functional integration of adult-born neurons within the hippocampus that resist homeostatic regulation with aging, rather than the absolute number of adult-born neurons, may be an essential feature of adult neurogenesis that promotes the maintenance of neural plasticity in old age.

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

Describe the epidemiology and impact of late diagnosis among older adults living with HIV and estimate age at infection. Comparative national analyses between individuals diagnosed when aged 50 years and over with individuals diagnosed prior to 50 years. Age at infection was estimated using CD4 cell count at diagnosis. A total of 8255 older adults accessed HIV care in England, Wales and Northern Ireland in 2007, a 3.5-fold increase compared to 2000; with one in 10 individuals newly diagnosed in 2007. When compared with younger adults at diagnosis, older adults were significantly more likely to be men (74 vs. 58%; P < 0.001), infected through sex between men (40 vs. 34%; P < 0.001) and of white ethnicity (60 vs. 38%; P < 0.001). Older heterosexual adults were more likely to be infected within the UK (16 vs. 12%; P < 0.001), with evidence of travel abroad among white heterosexual men. Almost half (48%) of older adults were late presenters vs. a third (33%) of younger adults. Older late presenters were 14 times more likely to die within a year of diagnosis compared with older adults who were not diagnosed late (14 vs. 1%; P < 0.001) and had 2.4 times the risk of dying than younger late presenters. We estimate that nearly half (48%) of older adults diagnosed between 2000 and 2007 acquired their infection at age 50 and over. Our study provides evidence of HIV transmission, high rates of late presentation and an increased risk of short-term mortality among older adults. These findings highlight the need for increased targeted prevention efforts and strategies to increase HIV testing among older adults at risk of HIV.

Although the incidence of ET increases with advancing age, the disease may begin at any age, including childhood. The question arises as to whether childhood-onset ET cases manifest the same sets of pathological changes in the cerebellum as those whose onset is during adult life. We quantified a broad range of postmortem features (Purkinje cell [PC] counts, PC axonal torpedoes, a host of associated axonal changes [PC axonal recurrent collateral count, PC thickened axonal profile count, PC axonal branching count], heterotopic PCs, and basket cell rating) in 60 ET cases (11 childhood-onset and 49 adult-onset) and 30 controls. Compared to controls, childhood-onset ET cases had lower PC counts, higher torpedo counts, higher heterotopic PC counts, higher basket cell plexus rating, and marginally higher PC axonal recurrent collateral counts. The median PC thickened axonal profile count and median PC axonal branching count were two to five times higher in childhood-onset ET than controls, but the differences did not reach statistical significance. Childhood-onset and adult-onset ET had similar PC counts, torpedo counts, heterotopic PC counts, basket cell plexus rating, PC axonal recurrent collateral counts, PC thickened axonal profile count and PC axonal branching count. In conclusion, we found that childhood-onset and adult-onset ET shared similar pathological changes in the cerebellum. The data suggest that pathological changes we have observed in the cerebellum in ET are a part of the pathophysiological cascade of events in both forms of the disease and that both groups seem to reach the same pathological endpoints at a similar age of death.

Background Young adults display substantial weight gain. Preventing this age-related weight gain would reduce overweight and obesity. Objective We evaluated an internet based intervention using Internet-connected scales and graphic email feedback; the Caloric Titration Method (CTM), to reduce age-related weight gain over the course of 1 y among first-year college students. Design First-year college students (n=167) were randomized to (CTM) or control (C) group. Both groups were provided Internet-connected scales. CTM group was instructed to weigh daily, view a weight graph emailed to them after weighing, and try to maintain their weight as indicated in the graph. The C group could weigh at any time, but did not receive feedback. At six months and 1 year the C group were notified to provide weights. Intention to treat analysis, using a mixed model adjusted for baseline weight, BMI and gender was used to analyze the effect of the intervention. Results Baseline Body Mass Index was 22.9 ± 3.0 kg/m2. Frequency of self-weighing (median) was 5 times/week in the CTM group, compared to 1 time/week in C (p<0.001). Ninety-five percent of the CTM participants weighed ≥3 times/week, compared to 15% in C group (p<0.001). After 1 year the C group had gained 1.1 ± 4.4 kg whereas the CTM group lost 0.5 ± 3.7 kg, yielding a significant overall time*group interaction (F=3.39, p=0.035). The difference in weight change between the two groups at 1 year was significant (p=0.004). Weight change of the CTM group was not different from zero whereas weight gain in C group was significant. Retention was 81%. Conclusions The internet based frequent self-weighing CTM system was effective in preventing age-related weight gain in young adults over one year and thus offers promise to reduce overweight and obesity.

In June 2016, South Africa implemented legislation mandating maximum sodium levels in a range of processed foods with a goal of reducing population salt intake and disease burden from hypertension. Our aim was to explore the relationship between salt and blood pressure (BP) in a subsample of the World Health Organization Study on global AGEing and adult health (SAGE) Wave 2 before implementation of legislation in South Africa. Blood pressure (BP) was measured in triplicate (n = 2722; median age 56 years; 33% male) and 24-h urine collected in a nested subsample (n = 526) for sodium, potassium and creatinine analysis. Hypertension prevalence was 55% in older adults (50-plus years) and 28% in younger adults (18-49 years). Median salt intake (6.8 g/day) was higher in younger than older adults (8.6 g vs 6.1 g/day; p < 0.001), and in urban compared to rural populations (7.0 g vs 6.0 g/day; p = 0.033). Overall, 69% of participants had salt intakes above 5 g/day. Potassium intakes were generally low (median 35 mmol/day) with significantly lower intakes in rural areas and older adults. Overall, 91% of adults failed to meet the daily potassium recommendation of 90 mmol/d. Salt intakes above 5 g/day, and to a greater extent, a dietary sodium-to-potassium (Na:K) ratio above 2 mmol/mmol, were associated with significantly steeper regression slopes of BP with age. These preliminary results indicate that high dietary Na:K ratio may lead to a greater increase in BP and hypertension risk with age. Interventions to increase potassium intakes alongside sodium reduction initiatives may be warranted.

The goal of the current investigation was to analyze ability emotional intelligence (EI) in a large cross-sectional sample of Spanish adults (N = 12,198; males, 56.56%) aged from 17 to 76 years (M = 37.71, SD = 12.66). Using the Mayer-Salovey-Caruso Emotional Intelligence Test (MSCEIT), which measures ability EI according to the 4 branches of the Mayer and Salovey EI model. The authors examined effects of gender on ability EI, as well as the linear and quadratic effects of age. Results suggest that gender affects the total ability EI score as well as scores on the 4 EI branches. Ability EI was greater in women than men. Ability EI varied with age according to an inverted-U curve: Younger and older adults scored lower on ability EI than middle-aged adults, except for the branch of understanding emotions. These findings strongly support the idea that both gender and age significantly influence ability EI during aging. (PsycINFO Database Record (c) 2016 APA, all rights reserved).

Older adults continue to be underrepresented in clinical research despite their burgeoning population in the United States and worldwide. Physicians often propose treatment plans for older adults based on data from studies involving primarily younger, more-functional, healthier participants. Major barriers to recruitment of older adults in aging research relate to their substantial health problems, social and cultural barriers, and potentially impaired capacity to provide informed consent. Institutionalized older adults offer another layer of complexity that requires cooperation from the institutions to participate in research activities. This paper provides study recruitment and retention techniques and strategies to address concerns and overcome barriers to older adult participation in clinical research. Key approaches include early in-depth planning; minimizing exclusion criteria; securing cooperation from all interested parties; using advisory boards, timely screening, identification, and approach of eligible patients; carefully reviewing the benefit:risk ratio to be sure it is appropriate; and employing strategies to ensure successful retention across the continuum of care. Targeting specific strategies to the condition, site, and population of interest and anticipating potential problems and promptly employing predeveloped contingency plans are keys to effective recruitment and retention.

Previous neuroimaging and behavioral studies demonstrated structural and functional changes in the motor system across childhood. However, it is unclear what functionally relevant electrocortical processes underlie developmental differences in motor planning and control during multijoint, goal-directed movements. The current study characterized age-related differences in electrocortical processes during the performance of discrete aiming movements in children and adults. Electroencephalography and movement kinematics were recorded from 3 groups of participants (n = 15 each): young children (mean 6.7 years), older children (mean 10.2 years), and adults (mean 22.1 years). Age-related differences were evident in the electroencephalographic (EEG) signals. First, young children exhibited less movement-related activity in task-relevant motor areas compared with adults (movement-related cortical potentials). Second, young children exhibited greater activation (less alpha power) of the frontal areas and less activation of the parietal areas as compared with the other groups. At the behavioral level, young children made slower and jerkier movements, with less consistent directional planning compared with older children and adults. Significant correlations were also found between EEG and movement kinematic measures. Taken together, the results of this study provide evidence that age-related differences in the quality of motor planning and performance are reflected in the differences in electrocortical dynamics among children and adults.

In October 2015, the Advisory Committee on Immunization Practices (ACIP)* approved the Recommended Immunization Schedule for Adults Aged 19 Years or Older, United States, 2016. This schedule provides a summary of ACIP recommendations for the use of vaccines routinely recommended for adults aged 19 years or older in two figures, footnotes for each vaccine, and a table that describes primary contraindications and precautions for commonly used vaccines for adults. Although the figures in the adult immunization schedule illustrate recommended vaccinations that begin at age 19 years, the footnotes contain information on vaccines that are recommended for adults that may begin at age younger than age 19 years. The footnotes also contain vaccine dosing, intervals between doses, and other important information and should be read with the figures.

Introduction Acute myeloid leukemia (AML) is a heterogeneous clonal disorder of haemopoietic progenitor cells diagnosed in individuals of any age, but with a median age of 67 years at presentation in adults. Assessment of the mutation status of Nucleophosmin protein-1 (NPM1) and FMS-like tyrosine kinase 3 internal tandem duplication (FLT3-ITD) are essential for the diagnosis, prognosis and treatment of AML. Methods A total of 160 de novo AML cases, both cytogenetically normal and abnormal, were analyzed for the presence of NPM1 and FLT3-ITD mutations and the results assessed in conjunction with epidemiological, clinical and laboratory findings. Results NPM1 mutations were found in 7.5%, while FLT3-ITD was present in 12% of these cases. Both of these were lower than expected. The median age at diagnosis of AML was 41 years and for the FLT3-ITD only cases, median age was 33 years; these ages were younger than expected. Conclusion The lower reported frequencies and younger median age at diagnosis of AML and these specific mutations may be contributed to by a number of factors including; effects of race on age of presentation, inclusion of patients diagnosed with de novo AML only and a generally younger median age of the South African population.

Suicide is a leading cause of death for transition-aged youth (TAY), and yet few studies examine correlates of suicidal ideation specifically in this age demographic (age 18-24 years). The transition to adulthood is a unique context, marked by novel stressors (e.g., joining the workforce) and increased independence, which may influence risk factors for suicidal ideation. This study examined correlates of suicidal ideation in TAY and adults and contrasted profiles across age. We used 4 biannual cycles (2005, 2007, 2009, 2011) of the Canadian Community Health Survey, a population-based cross-sectional survey on health. We used logistic regression to assess the association between suicidal ideation and depression, distress, alcohol use, smoking, exercise, sedentary behaviour, chronic illness, restrictions to daily living, perceived physical and mental health, and perceived social support independently in both TAY ( n = 4427) and adults ( n = 14,452). We subsequently assessed possible interactions with age (18-24 v. 25-44 years) and sex and differences in help-seeking behaviour in a combined model. TAY exhibited higher rates of suicidal ideation than adults did ( P < 0.001). Numerous factors were associated with suicidal ideation in TAY. Notably, alcohol abstinence was associated with decreased suicidal ideation in TAY but not for adults. Moreover, when depressed, TAY were significantly less likely to have received professional mental health help than adults (odds ratio = 0.64, 95% CI, 0.43 to 0.94). Suicidal ideation is more prevalent in TAY than adults, and its consequences may be aggravated by poor treatment-seeking behaviour in at-risk (i.e. depressed) individuals. These different risk profiles substantiate the recent shift toward clinical interventions focusing on transition-aged youth, rather than traditional child (<18 years) and adult (>18 years) services.

The incidence of colorectal cancer in adolescent and young adult patients is increasing. However, survival and clinical features of young patients, especially those with stage IV disease, relative to adult patients remain unclear. This retrospective single-institution cohort study was conducted at a tertiary care cancer center. Subjects were 861 consecutive patients who were diagnosed with stage IV colorectal cancer at the age of 15 to 74 years and who were referred to the division of surgery or gastrointestinal oncology at the National Cancer Center Hospital from 1999 to 2013. Overall survival (OS) was investigated and clinicopathological variables were analyzed for prognostic significance. Of these, 66 (8%) were adolescent and young adult patients and 795 (92%) were adult patients. Median survival time was 13.6 months in adolescent and young adult patients and 22.4 months in adult patients, and 5-year OS rates were 17.3% and 20.3%, respectively, indicating significant worse prognosis of adolescent and young adult patients (p = 0.042). However, age itself was not an independent factor associated with prognosis by multivariate analysis. When compared with adult patients, adolescent and young adult patients consisted of higher proportion of the patients who did not undergo resection of primary tumor, which was an independent factor associated with poor prognosis in multivariate analysis. In patients who did not undergo resection (n = 349), OS of adolescent and young adult patients were significantly worse (p = 0.033). Prognoses were worse in adolescent and young adult patients with stage IV colorectal cancer compared to adult patients in Japan, due to a higher proportion of patients who did not undergo resection with more advanced and severe disease, but not due to age itself.

The third molar tooth, known as the "wisdom tooth," is the only tooth that can be used to determine legal adult age. This study aimed to test the accuracy of Cameriere's third molar maturity index (I 3M ) in assessing the legal adult age of 18 years in the Kosovar population. Orthopantomographs (OPTs) of 1221 healthy living Kosovar individuals, aged between 12 and 23 years and with no congenital or developmental anomalies, were analyzed. Intra-class correlation coefficients were 0.858 (95% CI, 0.786 to 0.906) and 0.852 (95% CI, 0.779 to 0.903) for intra-rater and for inter-rater agreement, respectively. The sample was divided into training dataset (800 OPTs) and test dataset (421 OPTs). The training dataset was used to generate the logistic regression model, while the test dataset was used to study the performance of the model. I 3M and gender as independent variables and adult age (≥ 18 years) or minor age (< 18 years) as the dependent variable were used for logistic regression analysis. The receiver operating curve (ROC) analysis was used to determine the specific cut-off value of I 3M for predicting adult age. The results showed that only I 3M statistically significantly contributed to discriminating adults and minors. ROC analysis showed that the cut-off value of I 3M  < 0.08 was the best in discriminating adults and minors. An analysis of the test dataset (421 OPTs) showed that as I 3M decreased the age gradually increased. The performance of the cut-off value of I 3M  < 0.08, to discriminate between adults and minors, was analyzed by contingency tables for both sexes. In males, the accurate classification (Acc) was 0.968 (95% CI, 0.926 to 0.985), the sensitivity (Se) was 0.962 (95% CI, 0.925 to 0.978), and the specificity (Sp) was 0.976 (95% CI, 0.929 to 0.995). The Bayes post-test probability (Bayes PTP) was 0.975 (95% CI, 0.905 to 1.00). In females, Acc was 0.909 (95% CI, 0.870 to 0.917), Se and Sp were 0.826 (95% CI, 0.787 to 0.834) and 0

Age related optic nerve axonal loss in adult Brown Norway rats.

The effect of age on the number and morphology of optic nerve axons in adult Brown Norway rats (5-31 months old) (n=29) was examined using transmission electron microscopy (TEM). By manually counting every axon in areas representing 60% of the optic nerve cross-section, we found a significant negative correlation between age and axon count (R(2)=0.18, P<0.05). However, when the oldest animals were omitted, the relationship was no longer statistically significant. Simultaneously, the proportion of spontaneously degenerating axons increased at an exponential rate (R(2)=0.79, P<0.05), with significantly more degeneration in the 31-month group than in 5-month-old animals (ANOVA, P<0.05). This study demonstrates, using quantitative TEM methods, that optic nerve axonal numbers are relatively constant throughout the majority of the adult life of the Brown Norway rat, an increasingly popular strain for glaucoma research. Total axonal loss with aging is substantially less than that reported for other strains. The reduction in axonal numbers and the rate of axonal degeneration do not appear significantly altered until the last few months of life, failing to support some studies that have concluded that optic nerve axon loss in adult rats is linear. However, they do agree with other studies in the rat, and a similar study performed in non-human primate eyes, that concluded that aging changes in the optic nerve and retina follow a complex pattern. Therefore, the impact of animal age must be considered when modeling the course and pathophysiology of experimental glaucomatous optic nerve damage in rats.

Glucoregulatory responses of adult and aged rats after exposure to chronic stress.

Odio, M R; Brodish, A

Stress has been implicated as an environmental factor that may accelerate the process of biological aging. However, this proposal has remained largely anecdotal due to relatively few studies that directly tested this hypothesis. In the present experiments groups of 6-month-old and 20-month-old male F-344 rats were chronically stressed for a six-month period. After the last stress session, when the animals were 12 months of age (adult) and 26 months of age (old), control and chronically stressed rats were tested for their ability to: (a) elicit glucose and insulin responses to an acute, novel stressor; (b) remove a circulatory glucose load elicited either by acute stress exposure or by injection of d-glucose; and (c) raise insulin levels after a glucose challenge. In control rats, we observed a deficit in each of these parameters in old compared to adult rats. Exposure to chronic stress did not exacerbate deterioration of these response mechanisms in either adult or old rats. In fact, the data showed a modest improvement in glucose tolerance in chronically stressed compared to age-matched control rats. We conclude that chronic stress did not exacerbate age-dependent decline of glucoregulatory capacity. From these results and from our earlier work, we speculate that the decline during aging of the functional integrity of systems involved in the response to stress may be sustained by periodic challenges from the organism's external environment.

Iterative dip-steering median filter

Seismic data are always contaminated with high noise components, which present processing challenges especially for signal preservation and its true amplitude response. This paper deals with an extension of the conventional median filter, which is widely used in random noise attenuation. It is known that the standard median filter works well with laterally aligned coherent events but cannot handle steep events, especially events with conflicting dips. In this paper, an iterative dip-steering median filter is proposed for the attenuation of random noise in the presence of multiple dips. The filter first identifies the dominant dips inside an optimized processing window by a Fourier-radial transform in the frequency-wavenumber domain. The optimum size of the processing window depends on the intensity of random noise that needs to be attenuated and the amount of signal to be preserved. It then applies median filter along the dominant dip and retains the signals. Iterations are adopted to process the residual signals along the remaining dominant dips in a descending sequence, until all signals have been retained. The method is tested by both synthetic and field data gathers and also compared with the commonly used f-k least squares de-noising and f-x deconvolution.

Active aging is central to enhancing the quality of life for older adults, but its conceptualization is not often made explicit for Asian elderly people. Little is known about active aging in older Thai adults, and there has been no development of scales to measure the expression of active aging attributes. The aim of this study was to develop a culturally relevant composite scale of active aging for Thai adults (AAS-Thai) and to evaluate its reliability and validity. EIGHT STEPS OF SCALE DEVELOPMENT WERE FOLLOWED: 1) using focus groups and in-depth interviews, 2) gathering input from existing studies, 3) developing preliminary quantitative measures, 4) reviewing for content validity by an expert panel, 5) conducting cognitive interviews, 6) pilot testing, 7) performing a nationwide survey, and 8) testing psychometric properties. In a nationwide survey, 500 subjects were randomly recruited using a stratified sampling technique. Statistical analyses included exploratory factor analysis, item analysis, and measures of internal consistency, concurrent validity, and test-retest reliability. Principal component factor analysis with varimax rotation resulted in a final 36-item scale consisting of seven factors of active aging: 1) being self-reliant, 2) being actively engaged with society, 3) developing spiritual wisdom, 4) building up financial security, 5) maintaining a healthy lifestyle, 6) engaging in active learning, and 7) strengthening family ties to ensure care in later life. These factors explained 69% of the total variance. Cronbach's alpha coefficient for the overall AAS-Thai was 0.95 and varied between 0.81 and 0.91 for the seven subscales. Concurrent validity and test-retest reliability were confirmed. The AAS-Thai demonstrated acceptable overall validity and reliability for measuring the multidimensional attributes of active aging in a Thai context. This newly developed instrument is ready for use as a screening tool to assess active aging levels among older

Exploring identity and aging: auto-photography and narratives of low income older adults.

This study focused on meanings of health, housing, independence and aging among low-income adults age 55 and older who live in, or are on a waiting list for, publicly subsidized rental housing. The purpose was to learn how low-income older adults perceive their independence and health, and how their place of residence contributes to these perceptions, as well as related perceptions of self. Qualitative data were collected using in-person narrative interviews with 45 individuals and a second photo elicitation interview with 31 of these persons. Themes describe how disrupted identities influence subjective thoughts about the aging process, housing, health, and finances, the process of clinicalization, and place identities. These findings highlight the relationship between housing status, dignity, and shifting identities as older adults experience the aging process in a low-income context. This study expands the current scholarship on the relationship between environment and aging as well as our understanding of poverty among older persons. These topics are relevant for new policies and programs to support the aging in place of older persons in subsidized housing. Understanding the life worlds of those who live in or have applied to this form of housing will be instrumental in developing such strategies. Copyright © 2014 Elsevier Inc. All rights reserved.

Normal Adult Aging and the Contextual Influences Affecting Speech and Meaningful Sound Perception

PubMed Central

Aydelott, Jennifer; Leech, Robert; Crinion, Jennifer

2010-01-01

It is widely accepted that hearing loss increases markedly with age, beginning in the fourth decade ISO 7029 (2000). Age-related hearing loss is typified by high-frequency threshold elevation and associated reductions in speech perception because speech sounds, especially consonants, become inaudible. Nevertheless, older adults often report additional and progressive difficulties in the perception and comprehension of speech, often highlighted in adverse listening conditions that exceed those reported by younger adults with a similar degree of high-frequency hearing loss (Dubno, Dirks, & Morgan) leading to communication difficulties and social isolation (Weinstein & Ventry). Some of the age-related decline in speech perception can be accounted for by peripheral sensory problems but cognitive aging can also be a contributing factor. In this article, we review findings from the psycholinguistic literature predominantly over the last four years and present a pilot study illustrating how normal age-related changes in cognition and the linguistic context can influence speech-processing difficulties in older adults. For significant progress in understanding and improving the auditory performance of aging listeners to be made, we discuss how future research will have to be much more specific not only about which interactions between auditory and cognitive abilities are critical but also how they are modulated in the brain.

Benefits of having friends in older ages: differential effects of informal social activities on well-being in middle-aged and older adults.

It has been considered a fact that informal social activities promote well-being in old age, irrespective of whether they are performed with friends or family members. Fundamental differences in the relationship quality between family members (obligatory) and friends (voluntary), however, suggest differential effects on well-being. Further, age-related changes in networks suggest age-differential effects of social activities on well-being, as older adults cease emotionally detrimental relationships. Longitudinal representative national survey study with middle-aged (n = 2,830) and older adults (n = 2,032). Age-differential effects of activities with family members and friends on changes in life satisfaction, positive affect (PA), and negative affect (NA) were examined in latent change score models. In the middle-aged group, activities with friends and families increased PA and life satisfaction and were unrelated to NA. In the older age group, family activities increased both PA and NA and were unrelated to changes in life satisfaction, but activities with friends increased PA and life satisfaction and decreased NA. Social activities differentially affect different facets of well-being. These associations change with age. In older adults, the effects of social activities with friends may become more important and may act as a buffer against negative effects of aging.

Childhood obesity is a major health concern. Excess adiposity during childhood affects growth and puberty. Our aim was to assess whether genetic adult height is compromised in adolescents with obesity. In a retrospective study of 190 obese patients followed at our Pediatric Endocrinology Institute, adult height and delta height (the difference between adult height and mid-parental height) were compared to those of 150 healthy age-matched normal-weight controls. Review of medical files yielded the relevant clinical and anthropometric data of patients, controls, and parents. Of the 190 obese adolescents, 150 were morbidly obese. The median adult height of morbidly obese males was 174.3 cm, of obese males 174 cm, and of normal-weight males 176 cm (p = 0.025). Delta height of morbidly obese males was -0.5 cm, of obese males -0.8 cm, and of normal-weight males, 3 cm (p < 0.0001). The median adult height of morbidly obese females was 161.3 cm, of obese females 162.8 cm, and of normal-weight females 162 cm (p = 0.37). Delta height of morbidly obese females was -1.85 cm, of obese females -0.95 cm, and of normal-weight females 0.7 cm (p = 0.019). Impairment of potential genetic height was not associated with obesity-related comorbidities. Adolescents with obesity showed impairment of potential genetic adult height as compared to that of normal-weight subjects. © 2017 S. Karger AG, Basel.

Predominantly antibody deficiencies (PADs) are the most common type of primary immunodeficiency in adults. PADs frequently pass undetected leading to delayed diagnosis, delayed treatment, and the potential for end-organ damage including bronchiectasis. In addition, PADs are frequently accompanied by comorbid autoimmune disease, and an increased risk of malignancy. To characterize the diagnostic and clinical features of adult PAD patients in Victoria, Australia. We identified adult patients receiving, or having previously received immunoglobulin replacement therapy for a PAD at four hospitals in metropolitan Melbourne, and retrospectively characterized their clinical and diagnostic features. 179 patients from The Royal Melbourne, Alfred and Austin Hospitals, and Monash Medical Centre were included in the study with a median age of 49.7 years (range: 16-87 years), of whom 98 (54.7%) were female. The majority of patients (116; 64.8%) met diagnostic criteria for common variable immunodeficiency (CVID), and 21 (11.7%) were diagnosed with X-linked agammaglobulinemia (XLA). Unclassified hypogammaglobulinemia (HGG) was described in 22 patients (12.3%), IgG subclass deficiency (IGSCD) in 12 (6.7%), and specific antibody deficiency (SpAD) in 4 individuals (2.2%). The remaining four patients had a diagnosis of Good syndrome (thymoma with immunodeficiency). There was no significant difference between the age at diagnosis of the disorders, with the exception of XLA, with a median age at diagnosis of less than 1 year. The median age of reported symptom onset was 20 years for those with a diagnosis of CVID, with a median age at diagnosis of 35 years. CVID patients experienced significantly more non-infectious complications, such as autoimmune cytopenias and lymphoproliferative disease, than the other antibody deficiency disorders. The presence of non-infectious complications was associated with significantly reduced survival in the cohort. Our data are largely

Proactive and retroactive transfer of middle age adults in a sequential motor learning task.

2015-03-01

We assessed the effects of aging in the transfer of motor learning in a sequential manual assembly task that is representative for real working conditions. On two different days, young (18-30 years) and middle-aged adults (50-65 years) practiced to build two products that consisted of the same six components but which had to be assembled in a partly different order. Assembly accuracy and movement time during tests, which were performed before and after the practice sessions, were compared to determine proactive and retroactive transfer. The results showed proactive facilitation (i.e., benefits from having learned the first product on learning the second one) in terms of an overall shortening of movement time in both age-groups. In addition, only the middle-aged adults were found to show sequence-specific proactive facilitation, in which the shortening of movement time was limited to components that had the same the order in the two products. Most likely, however, the sequence-specific transfer was an epiphenomenon of the comparatively low rate of learning among the middle-aged adults. The results, however, did reveal genuine differences between the groups for retroactive transfer (i.e., effects from learning the second product on performance of the first). Middle-aged adults tended to show more pronounced retroactive interference in terms of a general decrease in accuracy, while younger adults showed sequence-specific retroactive facilitation (i.e., shortening of movement times for components that had the same order in the two products), but only when they were fully accurate. Together this suggests that in the learning of sequential motor tasks the effects of age are more marked for retroactive transfer than for proactive transfer. Copyright © 2015 Elsevier B.V.

2015-02-01

The aim of this study was to analyse the relationship between early unemployment (ages 16-21 years) and adult hypertension after controlling for earlier hypertension, unemployment in adult life, risk factors for hypertension and confounders. A cohort of 927 (86.6% of the original cohort) 9th grade school-leavers was followed from 1981 until 2008. Data were collected through questionnaires, health examinations, and national registers. Univariate and multivariate logistic regression were used as primary statistical methods. At ages 21 and 43, hypertension was significantly more prevalent among men than women (p < .001). Unemployment between the ages of 16 and 21 was related to hypertension at age 43 among women but not men. The odds ratio (OR) was persistently high (OR 3.16 [95% confidence interval 1.45-6.89]) after controlling for late unemployment, hypertension at age 16, risk factors for hypertension and confounders. There was no significant relationship between exposure to early unemployment and hypertension at age 21 for women or men. From a public health perspective, youth unemployment is a societal problem in need of more attention and intervention in order to prevent long-term adverse health outcomes. © 2014 the Nordic Societies of Public Health.

Cognitive behaviour therapy for generalized anxiety disorder: Is CBT equally efficacious in adults of working age and older adults?

2017-03-01

The current meta-analysis compared the efficacy of CBT for GAD between adults of working age and older people. In addition, we conducted a qualitative content analysis of treatment protocols used in studies with older clients to explore potential factors that may enhance treatment outcomes with this particular client group. Applying the inclusion criteria resulted in the identification of 15 studies with 22 comparisons between CBT and control groups (770 patients). When examining overall effect sizes for CBT for GAD between older people and adults of working age there were no statistically significant differences in outcome. However, overall effect size of CBT for GAD was moderate for older people (g=0.55, 95% CI 0.22-0.88) and large for adults of working age (g=0.94, 95% CI 0.52-1.36), suggesting that there is still room for improvement in CBT with older people. The main difference in outcome between CBT for GAD between the two age groups was related to methodological quality in that no older people studies used an intention-to-treat design. The content analysis demonstrated that studies with older clients were conducted according to robust CBT protocols but did not take account of gerontological evidence to make them more age-appropriate.

2012-11-01

The investigations of the risk factors for suicidal ideation among middle-aged adults may be especially important for predicting suicidal actions, given the steep increase in suicide among Koreans aged 45-54. Few studies have sought to investigate the effect of socio-demographic status on suicidal ideation among middle-aged adults. This study investigated the influence of socio-demographic status on suicidal ideation among middle-aged adults in South Korea. The sample consisted of middle-aged men (n = 3,214) and middle-aged women (n = 4,087) aged 40-64 years who had participated in the 2005 cross-sectional Seoul Citizens Health and Social Indicators Survey. Using multiple logistic regression analysis, we examined the effect of socio-demographic status, health behaviours and health status on suicidal ideation in middle-aged adults. The outstanding finding was that suicidal ideation was most prevalent among middle-aged women who engaged in manual labour (i.e. blue-collar workers) (OR = 2.77, 95% CI = 1.20-6.42). The absence of a spouse was significantly associated with suicidal ideation among middle-aged men (OR = 2.10, 95% CI = 1.30-3.40). The effect of enhanced security related to stable employment was strongest among middle-aged women in blue-collar jobs, and the effect of intensive counselling services was strongest among divorced or widowed middle-aged men.

Study Objectives: To investigate the restorative quality of sleep and daytime functioning in sleepwalking adult patients in comparison with controls. Design: Prospective case-control study. Setting: Data were collected at the Sleep Disorders Center, Hôpital-Gui-de Chauliac, Montpellier, France between June 2007 and January 2011. Participants: There were 140 adult sleepwalkers (100 (median age 30 y, 55% male) in whom primary SW was diagnosed) who underwent 1 night of video polysomnography. All patients participated in a standardized clinical interview and completed a battery of questionnaires to assess clinical characteristics of parasomnia, daytime sleepiness, fatigue, insomnia, depressive and anxiety symptoms, and health-related quality of life. Results were compared with those of 100 sex- and age-matched normal controls. Interventions: N/A. Measurements and Results: Of the sleepwalkers, 22.3% presented with daily episodes and 43.5% presented with weekly episodes. Median age at sleepwalking onset was 9 y. Familial history of sleepwalking was reported in 56.6% of sleepwalkers and violent sleep related behaviors in 57.9%, including injuries requiring medical care for at least one episode in 17%. Significant associations were found between sleepwalking and daytime sleepiness, fatigue, insomnia, depressive and anxiety symptoms, and altered quality of life. Early-onset sleepwalkers had higher frequency of violent behaviors and injuries. Sleepwalkers with violent behaviors had higher frequency of sleep terrors and triggering factors, with greater alteration in health-related quality of life. Conclusion: Adult sleepwalking is a potentially serious condition that may induce violent behaviors, self-injury or injury to bed partners, sleep disruption, excessive daytime sleepiness, fatigue, and psychological distress, all of which affect health-related quality of life.

This study examined the impact of Hurricanes Katrina and Rita on cognitive and psychosocial functioning among middle-aged (45–64 years), older (65–89 years) and oldest-old adults (90 years and over) in the Louisiana Healthy Aging Study (LHAS). Analyses of pre- and post-disaster cognitive data showed storm-related decrements in working memory for the middle-aged and older adults, but not for the oldest-old adults. Regression analyses confirmed that measures of social engagement and storm-related disruption significantly predicted pre- to post-disaster differences in short-term and working memory performance for the middle-aged and older adults only. These results are consistent with a burden perspective on post-disaster psychological reactions. Implications for current views of disaster reactions are discussed. PMID:21461124

Introduction Few studies have assessed the association between exposure to movie smoking and urge to smoke under real-world conditions. Methods We conducted exit interviews with 4,073 movie patrons, of whom 2,817 were aged 18 years or older. Some 536 were smokers and had complete data. Subjects had exited 26 movies, of which 12 contained smoking. We used least squares regression to assess the association between exposure to movie smoking and urge to smoke (scale range 0–10), controlling for movie rating, age, sex, heaviness of smoking index (HSI, range 0–6), and time since last cigarette smoked. Results Median age was 27 years and 52% were female. Median urge to smoke level at movie exit was 7. The dose–response between higher categories of movie smoking and median urge to smoke was one point for two lower categories (1–11 and 11–54 s) and two for the highest category (≥55 s), but these differences were not statistically significant. In the multivariate analysis, attendance of a movie with smoking was associated with a 0.81-point increase (95% CI = 0.46–1.16) in urge to smoke. For comparison, an HSI score of 3 (vs. 0) was associated with a 2-point increase in urge to smoke. Discussion In this sample of adult smokers, exposure to movie smoking was associated with higher urge to smoke after the movie, independent of movie rating. The effect size was consistent with responses seen in cue reactivity experiments. Exposure to movie smoking may affect urge to smoke among adult smokers. PMID:19542516

The study identifies differences in age-expectations between older adults from Korean, Chinese, Latino, and African American backgrounds living in the United States. This study uses baseline demographic, age-expectation, social, and health data from 229 racial/ethnic minority seniors in a stroke-prevention intervention trial. Unadjusted regression models and pair-wise comparisons tested for racial/ethnic differences in age-expectations, overall, and across domain subscales (e.g., physical-health expectations). Adjusted regression models tested whether age-expectations differed across racial/ethnic groups after controlling for demographic, social, and health variables. Regression and negative binomial models tested whether age-expectations were consistently associated with health and well-being across racial/ethnic groups. Age-expectations differed by race/ethnicity, overall and for each subscale. African American participants expected the least age-related functional decline and Chinese American participants expected the most decline. Although African American participants expected less decline than Latino participants in unadjusted models, they had comparable expectations adjusting for education. Latino and African American participants consistently expected less decline than Korean and Chinese Americans. Acculturation was not consistently related to age-expectations among immigrant participants over and above ethnicity. Although some previously observed links between expectations and health replicated across racial/ethnic groups, in adjusted models age-expectations were only related to depression for Latino participants. With a growing racial/ethnic minority older population in the United States, it is important to note older adults' age-expectations differ by race/ethnicity. Moreover, expectation-health associations may not always generalize across diverse samples. © The Author 2017. Published by Oxford University Press on behalf of The Gerontological Society

Price effects on the smoking behaviour of adult age groups.

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

Effects of Aging and Adult-Onset Hearing Loss on Cortical Auditory Regions

PubMed Central

Cardin, Velia

2016-01-01

Hearing loss is a common feature in human aging. It has been argued that dysfunctions in central processing are important contributing factors to hearing loss during older age. Aging also has well documented consequences for neural structure and function, but it is not clear how these effects interact with those that arise as a consequence of hearing loss. This paper reviews the effects of aging and adult-onset hearing loss in the structure and function of cortical auditory regions. The evidence reviewed suggests that aging and hearing loss result in atrophy of cortical auditory regions and stronger engagement of networks involved in the detection of salient events, adaptive control and re-allocation of attention. These cortical mechanisms are engaged during listening in effortful conditions in normal hearing individuals. Therefore, as a consequence of aging and hearing loss, all listening becomes effortful and cognitive load is constantly high, reducing the amount of available cognitive resources. This constant effortful listening and reduced cognitive spare capacity could be what accelerates cognitive decline in older adults with hearing loss. PMID:27242405

Social support networks are crucial for the health of older adults; however, personal characteristics and time of life may diminish the protective effect of social support. to determine if the presence of social support networks were associated with cognitive impairment among Mexican adults aged 50 or older and if this relationship was different based on age. This study analyzed data from the National Representation Survey performed in Mexico, Study on Global Ageing (SAGE) wave 1. Cognitive function was evaluated by a standardized test, social support was evaluated through latent class analysis (LCA). The LCA was run to obtain three subgroups of different Social Support Levels (SSL): low, medium, and high. Logistic regression models, stratified by age, were performed to analyze the association between SSL and cognitive function. For respondents ages 71-80 y/o, there was an inverse relationship with cognitive impairment for those with medium (OR 0.23, p=0.020) and high (OR 0.07, p=0.000) SSL in comparison with low SSL. While social support helped to improve cognitive function in older adults aged 71-80, this same association was not observed in adults of other ages. Those younger than 70 y/o may not need such a strong support network as a result of being more self-sufficient. After 80, social networks were not enough to help diminish the negative impact of cognitive impairment. Social support could improve the cognitive function of adults ages 71 and 80; suggesting there could be a window of opportunity to improve cognitive functioning for this group.

Several studies suggest that young patients may derive less oncologic benefit from surgical resection of cancers compared with older patients. We hypothesized that young patients may have worse outcomes following cytoreductive surgery with hyperthermic intraperitoneal chemoperfusion (CRS/HIPEC) for peritoneal metastases. Perioperative and oncologic outcomes in adolescent and young adults (AYA), defined as younger than age 40 years (n = 135), undergoing CRS/HIPEC between 2001 and 2015 were reviewed and compared with middle-aged adults, defined as aged 40-65 years (n = 684). The two groups were similar with regards to perioperative characteristics except that AYA were more likely to be symptomatic at presentation (65.2 vs. 50.9%, p = 0.003), had lower Charleson comorbidity index (median 6 vs. 8, p < 0.001), were less likely to receive neoadjuvant chemotherapy (32.8 vs. 42.5%, p = 0.042), and had longer operative times (median 543 vs. 493 min, p = 0.010). Postoperative Clavien-Dindo grade 3-4 morbidity was lower in AYA (17 vs. 26%, p = 0.029), and they required fewer reoperations for complications (3.7 vs. 10.4%, p = 0.014). AYA had longer median overall survival (103.6 vs. 73.2 months, p = 0.053). In a multivariate Cox regression analysis, age was an independent predictor of improved overall survival [hazard ratio 0.705; 0.516-0.963, p = 0.028]. Young patients with peritoneal metastases derive similar benefits from CRS/HIPEC as middle-aged patients. Young age should not be a deterrent to consideration of CRS/HIPEC for peritoneal metastases.

This paper describes a novel image filtering method that removes random-valued impulse noise superimposed on a natural color image. In impulse noise removal, it is essential to employ a switching-type filtering method, as used in the well-known switching median filter, to preserve the detail of an original image with good quality. In color image filtering, it is generally preferable to deal with the red (R), green (G), and blue (B) components of each pixel of a color image as elements of a vectorized signal, as in the well-known vector median filter, rather than as component-wise signals to prevent a color shift after filtering. By taking these fundamentals into consideration, we propose a switching-type vector median filter with non-local processing that mainly consists of a noise detector and a noise removal filter. Concretely, we propose a noise detector that proactively detects noise-corrupted pixels by focusing attention on the isolation tendencies of pixels of interest not in an input image but in difference images between RGB components. Furthermore, as the noise removal filter, we propose an extended version of the non-local median filter, we proposed previously for grayscale image processing, named the non-local vector median filter, which is designed for color image processing. The proposed method realizes a superior balance between the preservation of detail and impulse noise removal by proactive noise detection and non-local switching vector median filtering, respectively. The effectiveness and validity of the proposed method are verified in a series of experiments using natural color images.

This study examined how well older chemical dependency patients succeed in treatment relative to middle-aged and younger patients in a mixed-age private HMO outpatient program. To predict successful outcome, we tested a model incorporating age group differences in individual, treatment and extratreatment factors. The sample included 89 patients aged 55 and over, 379 patients aged 40 to 54, and 736 patients aged 18-39 (N = 1,204). Baseline measures included DSM-IV substance misuse diagnoses, Addiction Severity Index (ASI), psychiatric symptom checklist, sources of suggestion to enter treatment, treatment history and motivation. Outcome measures were abstinence rates and ASI score 6 months posttreatment. At baseline, older adults showed higher levels of alcohol dependence, lower rates of drug dependence and lower psychiatric symptoms relative to younger individuals. Source of suggestions to enter treatment differed by age. Older and middle-aged patients were more likely to have an abstinence goal and to stay in treatment longer than younger adults. At 6 months posttreatment, 55% of older adults reported abstinence in the preceding 30 days, versus 59% of middle-aged adults and 50% of younger adults (p = .035). Lower rates of dependence and hostility, and greater abstinence motivation and length of stay in treatment--all of which were associated with greater age--positively affect prognosis of older adults in treatment.

Meal and snack patterns are associated with energy and nutrient intakes and consequently health and nutritional status. The aim of this paper is to describe the percentage of daily energy intake from meals and afternoon snack among Malaysian adults. The study included a representative sample of adults aged 18-59 years (n=7349) from a nationwide Food Consumption Survey conducted by the Ministry of Health. Information on dietary intake was obtained using a one day 24-hour diet recall (24-HDR). Dietary data on 6886 adults were analysed using Nutritionist ProTM and statistical analysis was carried out using the SPSS 13.0. The median percentage of daily energy intake is reported only for adults consuming meals and afternoon tea and by socio-demographic characteristics as well as body mass index (BMI) status. More than 80% of Malaysian adults consumed morning meals, lunch and dinner and 54% reported having afternoon tea. The median percentage of energy intake from morning meals, lunch, dinner and afternoon tea was 29.9%, 30.5%, 32.4% and 17%, respectively. There were variations in the median percentage of energy from meals and snacks according to the socio-demographic variables and BMI status. It is important to understand the eating patterns of Malaysians as the information can assist in efforts to address obesity and diet-related chronic diseases among adults.

Aging successfully: oral health for the prime of life.

Niessen, Linda C; Fedele, Denise J

Aging is a worldwide phenomena. More adults, particularly those in developed countries, are living longer and healthier lives. The average US life expectancy was 47 years in 1900; by 2000, it had increased to 74 years. As the population ages, the number of adults with acute and chronic illnesses increases. The use of medications also increases with age. People over 65 years of age make up about 12% of the US population, but they consume 30% of all prescription medications, many of which can have a negative impact on oral health. Although tooth loss is declining in US adults, the need for various types of dental services in the adult population continues to increase. Data on the use of dental services has shown that dental visits by older adults correlate with the presence of teeth, not age. Research on the epidemiology of periodontal disease in older adults suggests that the disease in older adults is probably not due to greater susceptibility but, instead, the result of cumulative disease progression over time. Data on root caries has shown that exposed root surfaces, in combination with compromised health status and the use of multiple medications, can increase an older adult's risk for root caries. Oral candidiasis commonly occurs in immunocompromised individuals of any age, but in older adults, nursing home residents are particularly susceptible. Oral cancer is a disease of older adults, with a median age of 64 at diagnosis. Tobacco and alcohol use are the most common risk factors. Mental or physical impairments, such as dementing illnesses, or impaired dexterity as a result of arthritis or stroke, can impair an adult's ability to perform adequate oral self-care. Preventing oral diseases in older adults requires an understanding of the risk factors for oral diseases and how these risk factors change over time. Of particular concern are nursing home residents, who remain the most vulnerable of elders. Incorporating preventive oral health strategies into dental

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

Wavelet median denoising of ultrasound images

Macey, Katherine E.; Page, Wyatt H.

2002-05-01

Ultrasound images are contaminated with both additive and multiplicative noise, which is modeled by Gaussian and speckle noise respectively. Distinguishing small features such as fallopian tubes in the female genital tract in the noisy environment is problematic. A new method for noise reduction, Wavelet Median Denoising, is presented. Wavelet Median Denoising consists of performing a standard noise reduction technique, median filtering, in the wavelet domain. The new method is tested on 126 images, comprised of 9 original images each with 14 levels of Gaussian or speckle noise. Results for both separable and non-separable wavelets are evaluated, relative to soft-thresholding in the wavelet domain, using the signal-to-noise ratio and subjective assessment. The performance of Wavelet Median Denoising is comparable to that of soft-thresholding. Both methods are more successful in removing Gaussian noise than speckle noise. Wavelet Median Denoising outperforms soft-thresholding for a larger number of cases of speckle noise reduction than of Gaussian noise reduction. Noise reduction is more successful using non-separable wavelets than separable wavelets. When both methods are applied to ultrasound images obtained from a phantom of the female genital tract a small improvement is seen; however, a substantial improvement is required prior to clinical use.

Background Myelomeningocele (MMC) commonly causes impairments in body structure and functions as well as cognitive disabilities that can have an adverse effect on adult life. Improved medical care has resulted in increased numbers of individuals with MMC surviving to adulthood, however little is known about the impact of MMC on the lives of adults age 25 years or older. Objective To gain a better understanding of outcomes in education, employment, relationships, reproduction and life satisfaction of adults with MMC. Methods A primarily quantitative multiple-choice questionnaire designed to capture outcomes in education, employment, relationships and reproduction, along with a previously validated life satisfaction checklist (LiSat-11), was completed by adults with MMC. Relationships between demographic variables, outcomes and life satisfaction were determined using cross tabulation analysis, logistic regression and linear regression. Results Ninety adults with MMC, age 25 to 85 years (median age 32), reported a diverse range of outcomes in education, employment, relationships and reproduction. The most consistent variable associated with difficulty attaining adult milestones was hydrocephalus, the presence of which reduced the likelihood of living independently (p=<0.001), having a partner (p=0.003) and reproducing (p=<0.001), but did not contribute to reduced life satisfaction. Conclusions Adults with MMC, especially those without hydrocephalus, can obtain gainful employment, live independently, form partner relationships and have children, and these achievements contribute to life satisfaction. While MMC does not affect overall reported life satisfaction for adults, attention should be paid to specific domains with less reported satisfaction. PMID:23769483

Previous studies across species have established that the aging process adversely affects certain memory-related brain regions earlier than others. Behavioral tasks targeted at the function of vulnerable regions can provide noninvasive methods for assessing the integrity of particular components of memory throughout the lifespan. The present study modified a previous task designed to separately but concurrently test detailed memory for object identity and spatial location. Memory for objects or items is thought to rely on perirhinal and lateral entorhinal cortices, among the first targets of Alzheimer's related neurodegeneration. In line with prior work, we split an aged adult sample into "impaired" and "unimpaired" groups on the basis of a standardized word-learning task. The "impaired" group showed widespread difficulty with memory discrimination, whereas the "unimpaired" group showed difficulty with object, but not spatial memory discrimination. These findings support the hypothesized greater age-related impacts on memory for objects or items in older adults, perhaps even with healthy aging. © 2015 Wiley Periodicals, Inc. © 2015 Wiley Periodicals, Inc.

Retinal microvascular traits predict adverse health outcomes. The Singapore I Vessel Assessment (SIVA) software improved automated postprocessing of retinal photographs. In addition to microvessel caliber, it generates measures of arteriolar and venular geometry. Few studies addressed the reproducibility of SIVA measurements across a wide age range. In the current study, 2 blinded graders read images obtained by nonmydriatic retinal photography twice in 20 11-year-old children, born prematurely (n = 10) or at term (n = 10) and in 60 adults (age range, 18.9-86.1 years). Former preterm compared with term children had lower microvessel diameter and disorganized vessel geometry with no differences in intraobserver and interobserver variability. Among adults, microvessel caliber decreased with age and blood pressure and arteriolar geometry was inversely correlated with female sex and age. Intraobserver differences estimated by the Bland-Altman method did not reach significance for any measurement. Across measurements, median reproducibility (RM) expressed as percent of the average trait value was 8.8% in children (median intraclass correlation coefficient [ICC], 0.94) and 8.0% (0.97) in adults. Likewise, interobserver differences did not reach significance with RM (ICC) of 10.6% (0.85) in children and 10.4% (0.93) in adults. Reproducibility was best for microvessel caliber (intraobserver/interobserver RM, 4.7%/6.0%; ICC, 0.98/0.96), worst for venular geometry (17.0%/18.8%; 0.93/0.84), and intermediate for arteriolar geometry (10.9%/14.9%; 0.95/0.86). SIVA produces repeatable measures of the retinal microvasculature in former preterm and term children and in adults, thereby proving its usability from childhood to old age.

Age-related changes in late I-waves influence motor cortex plasticity induction in older adults.

Opie, George M; Cirillo, John; Semmler, John G

2018-04-18

The response to neuroplasticity interventions using transcranial magnetic stimulation (TMS) is reduced in older adults, which may be due, in part, to age-related alterations in interneuronal (I-wave) circuitry. The current study investigated age-related changes in interneuronal characteristics and whether they influence motor cortical plasticity in older adults. While I-wave recruitment was unaffected by age, there was a shift in the temporal characteristics of the late, but not early I-waves. Using I-wave periodicity repetitive TMS (iTMS), we showed that these differences in I-wave characteristics influence the induction of cortical plasticity in older adults. Previous research shows that neuroplasticity assessed using transcranial magnetic stimulation (TMS) is reduced in older adults. While this deficit is often assumed to represent altered synaptic modification processes, age-related changes in the interneuronal circuits activated by TMS may also contribute. Here we assessed age-related differences in the characteristics of the corticospinal indirect (I) waves and how they influence plasticity induction in primary motor cortex. Twenty young (23.7 ± 3.4 years) and 19 older adults (70.6 ± 6.0 years) participated in these studies. I-wave recruitment was assessed by changing the direction of the current used to activate the motor cortex, whereas short-interval intracortical facilitation (SICF) was recorded to assess facilitatory I-wave interactions. In a separate study, I-wave periodicity TMS (iTMS) was used to examine the effect of I-wave latency on motor cortex plasticity. Data from the motor evoked potential (MEP) onset latency produced using different coil orientations suggested that there were no age-related differences in preferential I-wave recruitment (P = 0.6). However, older adults demonstrated significant reductions in MEP facilitation at all 3 SICF peaks (all P-values < 0.05) and a delayed latency of the second and third SICF peaks (all P

Young adult (3-month-old) and aged (24-month-old) Fischer-344 male rats received i.v. infusions of 3H-labeled norepinephrine (NE) and epinephrine (EPI) to examine the effects of aging on the neuronal uptake of NE and sympathoadrenal release of NE and EPI. Spillovers of NE and EPI into plasma and their clearance from the circulation were estimated from plasma concentrations of endogenous and 3H-labeled NE and EPI. The efficiency of neuronal uptake was assessed from changes in plasma clearance of NE and concentrations of its intraneuronal metabolite, dihydroxyphenylglycol (DHPG), during immobilization stress or neuronal uptake blockade with desipramine. Stress-induced increases in plasma NE and higher plasma NE concentrations in aged compared to young adult rats were due to both decreases in NE clearance and increases in NE spillover. EPI spillover and clearance were reduced in aged compared to young adult rats, so that plasma EPI levels did not differ between groups. Young adult and aged rats had similar desipramine-induced decreases in NE clearance, whereas desipramine-sensitive decreases and stress-induced increases in plasma DHPG were larger in aged rats. This indicates that neuronal uptake is intact and that increased NE spillover at rest and during stress in aged rats reflects increased NE release from sympathetic nerves. The results show that aging is associated with divergent decreases in EPI release from the adrenal medulla and increases in NE release from sympathetic nerves. Increased plasma concentrations of NE in aged compared to young adult rats also result from decreased circulatory clearance of NE, but this does not reflect any age-related impairment of NE reuptake.

Life stage is an important risk factor for toxicity. Children and aging adults, for example, are more susceptible to certain chemicals than are young adults. In comparison to children, relatively little is known about susceptibility in older adults. Additionally, few studies have compared toxicant susceptibility across a broad range of life stages. Results are presented for behavioral evaluations of male Brown Norway rats obtained as adolescents (1 month), or young (4 months), middle-age (12 months) and senescent (24 months) adults. Motor activity was evaluated in photocell devices during 30-min sessions. Age-related baseline characteristics and sensitivity to toluene (0, 300, 650, or 1000mg/kg, p.o.) were determined. In Experiment 1, young-adult, middle-age and senescent rats were treated with corn-oil vehicle before five weekly test sessions. Baselines of horizontal and vertical activity decreased with age, but each age-group's averages remained stable across weeks of testing. Baseline activity of older rats was more variable than that of the young adults; older rats were also more variable individually from week to week. Toluene (1000mg/kg) increased horizontal activity proportionately more in senescent rats (ca. 300% of control) than in middle-age or young-adult rats (ca.145-175% of control). Experiment 2 established toluene dose-effect functions in individual adolescent, young-adult, middle-age and senescent rats; each rat received all treatments, counterbalanced across four weekly sessions. Toluene produced dose-related increases in horizontal activity that increased proportionately with age. Experiment 3 replicated the effects of toluene (1000mg/kg) in Experiment 1, showing that toluene-induced increases in horizontal activity were greatest in the oldest rats. Collectively, the results show that aging increased susceptibility to toluene and also increased variability in toluene response. Given the rapid growth of the aged population, further research is

Research exploring how places shape and interact with the lives of aging adults must be grounded in the places where aging adults live and participate. Combined participatory geospatial and qualitative methods have the potential to illuminate the complex processes enacted between person and place to create much-needed knowledge in this area. The purpose of this scoping review was to identify methods that can be used to study person-place relationships among aging adults and their neighborhoods by determining the extent and nature of research with aging adults that combines qualitative methods with participatory geospatial methods. A systematic search of nine databases identified 1,965 articles published from 1995 to late 2015. We extracted data and assessed whether the geospatial and qualitative methods were supported by a specified methodology, the methods of data analysis, and the extent of integration of geospatial and qualitative methods. Fifteen studies were included and used the photovoice method, global positioning system tracking plus interview, or go-along interviews. Most included articles provided sufficient detail about data collection methods, yet limited detail about methodologies supporting the study designs and/or data analysis. Approaches that combine participatory geospatial and qualitative methods are beginning to emerge in the aging literature. By more explicitly grounding studies in a methodology, better integrating different types of data during analysis, and reflecting on methods as they are applied, these methods can be further developed and utilized to provide crucial place-based knowledge that can support aging adults' health, well-being, engagement, and participation. © The Author 2017.

2013-04-01

The primary purpose of this paper is to undertake foundational research in the area of career readiness, work personality and age of onset with young adult central nervous system (CNS) survivors. Participants for this study consisted of 43 individuals whose age range from 18 to 30 (M = 21.64, SD = 3.46), an average age of brain tumor onset of 9.50 years (SD = 4.73) and average years off of treatment of 7.25 years (SD = 5.80). Packets were distributed to survivors who were participating in a psychosocial cancer treatment program. Participants completed multiple career instruments and a demographic form. Differences between groups and among the variables were examined and size effect sizes were analyzed. Young adult CNS survivors had significantly lower levels of work personality and career readiness when compared to young adult non-cancer survivors with CNS cancer with those between the ages of 6 and 12 reported significantly lower levels when compared to individuals diagnosed before age 6 and after the age of 13. Young adult CNS survivors at an increased risk for having lower levels of work personality and career readiness then a norm group comparison. Age of onset (between 6 and 12) may be at significant risk factor for developing poor or dysfunctional work and career behaviors. • Young adults with central nervous system (CNS) cancer are at particular risk for experiencing difficulties related to career and employment. • Work personality and career readiness are two constructs that have been found to be related to one's ability to meet the demands of work. • Young adult CNS cancer survivors have lower levels of work personality and career readiness. • Individuals diagnosed between the ages of 6 and 12 may be at particular risk and may need specific vocational rehabilitation interventions. • The results of this study point to the need for comprehensive career and vocational services for young adult CNS cancer survivors.

Are Older Adults Less Embodied? A Review of Age Effects through the Lens of Embodied Cognition

PubMed Central

Costello, Matthew C.; Bloesch, Emily K.

2017-01-01

Embodied cognition is a theoretical framework which posits that cognitive function is intimately intertwined with the body and physical actions. Although the field of psychology is increasingly accepting embodied cognition as a viable theory, it has rarely been employed in the gerontological literature. However, embodied cognition would appear to have explanatory power for aging research given that older adults typically manifest concurrent physical and mental changes, and that research has indicated a correlative relationship between such changes. The current paper reviews age-related changes in sensory processing, mental representation, and the action-perception relationship, exploring how each can be understood through the lens of embodied cognition. Compared to younger adults, older adults exhibit across all three domains an increased tendency to favor visual processing over bodily factors, leading to the conclusion that older adults are less embodied than young adults. We explore the significance of this finding in light of existing theoretical models of aging and argue that embodied cognition can benefit gerontological research by identifying further factors that can explain the cause of age-related declines.

Blow flies (Diptera: Calliphoridae) are typically the first insects to arrive at human remains and carrion. Predictable succession patterns and known larval development of necrophagous insects on vertebrate remains can assist a forensic entomologist with estimates of a minimum post-mortem interval (PMImin) range. However, adult blow flies are infrequently used to estimate the PMImin, but rather are used for a confirmation of larval species identification. Cuticular hydrocarbons have demonstrated potential for estimating adult blow fly age, as hydrocarbons are present throughout blow fly development, from egg to adult, and are stable structures. The goal of this study was to identify hydrocarbon profiles associated with the adults of a North American native blow fly species, Cochliomyia macellaria (Fabricius) and a North American invasive species, Chrysomya rufifacies (Macquart). Flies were reared at a constant temperature (25°C), a photoperiod of 14:10 (L:D) (h), and were provided water, sugar and powdered milk ad libitum. Ten adult females from each species were collected at day 1, 5, 10, 20, and 30 post-emergence. Hydrocarbon compounds were extracted and then identified using gas chromatography-mass spectrometry (GC-MS) analysis. A total of 37 and 35 compounds were detected from C. macellaria and Ch. rufifacies, respectively. There were 24 and 23 n-alkene and methyl-branched alkane hydrocarbons from C. macellaria and Ch. rufifacies, respectively (10 compounds were shared between species), used for statistical analysis. Non-metric multidimensional scaling analysis and permutational multivariate analysis of variance were used to analyze the hydrocarbon profiles with significant differences (P<0.001) detected among post-emergence age cohorts for each species, and unique hydrocarbon profiles detected as each adult blow fly species aged. This work provides empirical data that serve as a foundation for future research into improving PMImin estimates made by forensic

The role of different body fat indicators and age in assessing the prevalence of obesity is unclear. We aimed to examine to what extent different body fat indicators including BMI, waist circumference (WC) and waist-to-hip ratio (WHR) affect the prevalence of overweight and obesity among Chinese adults taking age into account. This population-based cross-sectional study included a random sample of 7,603 adults aged 20-79 years across entire Tianjin, China. BMI, WC, and WHR were used to define overweight and obesity following standard criteria. Prevalence rates were calculated and standardized using local age- and gender-specific census data. Logistic regression was used in data analysis. Using the combination of BMI, WC, and WHR, the prevalence of overweight and obesity was 69.8%, and increased with age till the age of 60 and a decline thereafter. The prevalence of overweight assessed by BMI was higher than that assessed by WC and WHR, while the prevalence of obesity defined by BMI was much lower than that defined by WC or WHR. The prevalence of overweight and obesity is about 70% among Chinese adults. Adiposity indicators and age play an important role in the prevalence of overweight and obesity. © 2016 S.

Age-related macular degeneration (AMD) is a complex disease resulting from the interplay of genetic predisposition and environmental exposures, and has been linked to oxidative stress and inflammatory mechanisms. Lead and cadmium can accumulate in human retinal tissues and may damage the retina through oxidative stress, and may thereby play a role in the development of AMD. We examined associations between blood lead, blood cadmium, and urinary cadmium concentrations and the presence of AMD in 5390 participants aged 40 years and older with blood lead and blood cadmium measures and a subsample of 1548 with urinary cadmium measures in the 2005–2008more » National Health and Nutrition Examination Surveys. AMD was identified by grading retinal photographs with a modification of the Wisconsin Age-Related Maculopathy Grading System. The weighted prevalence of AMD was 6.6% (n=426). Controlling for age, gender, race/ethnicity, education and body mass index, adults in the highest blood cadmium quartile had higher odds of AMD compared to the lowest quartile (odds ratio [OR], 1.56; 95% CI, 1.02–2.40), with a significant trend across quartiles (p-trend=0.02). After further adjustment for pack-years of cigarette smoking, estimates were somewhat attenuated (OR, 1.43; 95% CI, 0.91–2.27; p-trend=0.08). Similar associations were found with urinary cadmium. The association between urinary cadmium and AMD was stronger in non-Hispanic whites (NHW) than in non-Hispanic blacks (NHB) (OR, 3.31; 95% CI, 1.37–8.01 for levels above versus below the median among NHW; OR,1.45; 95% CI, 0.40–5.32 for levels above versus below the median among NHB; p-interaction=0.03). We found no association between blood lead levels and AMD. Higher cadmium body burden may increase risk of AMD, particularly among non-Hispanic white individuals; however, additional studies are needed before firm conclusions can be drawn. - Highlights: • We examined the association of cadmium and lead with age

Data from the National Health Interview Survey, 2013-2015 •From 2013 through 2015, the percentage of adults aged 18-64 who were uninsured at the time of interview decreased for poor (40.0% to 26.2%), near-poor (37.8% to 23.9%), and not-poor (11.7% to 7.7%) adults. •The percentage of adults aged 18-64 who had a usual place to go for medical care increased for poor (66.9% to 73.6%) and near-poor (71.1% to 75.9%) adults. •The percentage of adults aged 18-64 who had seen or talked to a health professional in the past 12 months increased for poor (73.2% to 75.8%) and near-poor (71.9% to 75.9%) adults. •The percentage of adults aged 18-64 who did not obtain needed medical care due to cost at some time during the past 12 months decreased for poor (16.8% to 12.4%), near-poor (14.6% to 11.0%), and not-poor (4.9% to 3.8%) adults. In 2014, U.S. adults could purchase a private health insurance plan through the Health Insurance Marketplace or state-based exchanges established as part of the Affordable Care Act (ACA). Additionally, under ACA some states opted to expand Medicaid coverage to low-income adults. Individuals living in or near poverty may have benefited disproportionately from these changes given their lower rates of health insurance coverage (1). Data from the 2013-2015 National Health Interview Survey (NHIS) are used to describe recent changes in health insurance coverage and selected measures of health care access and utilization for adults aged 18-64 by family poverty level.

To estimate differences in skeletal maturity and stature from birth to age 18 years between individuals who are overweight vs normal weight in young adulthood. Weight, length and height, and relative skeletal age (skeletal-chronological age) were assessed annually from birth to age 18 years in 521 subjects (255 women) in the Fels Longitudinal Study who were overweight or obese (body mass index (BMI) >25 kg m(-2), n=131) or normal weight (n=390) in young adulthood (18-30 years). Generalized estimating equations were used to test for skeletal maturity and stature differences by young adult BMI status. Differences in height increased during puberty, being significant for girls at ages 10 to 12 years, and for boys at ages 11 to 13 years (P-values<0.001), with overweight or obese adults being ∼3 cm taller at those ages than normal weight adults. These differences then diminished so that by age 18 years, overweight or obese adults were not significantly different in stature to their normal weight peers. Differences in skeletal maturity were similar, but more pervasive; overweight or obese adults were more skeletally advanced throughout childhood. Skeletal maturity differences peaked at chronological age 12 in boys and 14 in girls (P-values<0.001), with overweight or obese adults being ∼1 year more advanced than normal weight adults. This descriptive study is the first to track advanced skeletal maturity and linear growth acceleration throughout infancy, childhood and adolescence in individuals who become overweight, showing that differences occur primarily around the time of the pubertal growth spurt. Increased BMI in children on a path to becoming overweight adults precedes an advancement in skeletal development and subsequently tall stature during puberty. Further work is required to assess the predictive value of accelerated pubertal height growth for assessing obesity risk in a variety of populations.

We examined whether typical developmental trends in suggestion-induced false memories (i.e., age-related decrease) could be changed. Using theoretical principles from the spontaneous false memory field, we adapted 2 often-used false memory procedures: misinformation (Experiment 1) and memory conformity (Experiment 2). In Experiment 1, 7- to 9-year-old children (n = 33) and adults (n = 39) received stories containing associatively related details. They then listened to misinformation in the form of short narratives preserving the meaning of the story. Children and adults were equally susceptible to the misinformation effect. In Experiment 2, younger (7- to 8-year-olds, n = 30) and older (11- to 12-year-olds, n = 30) children and adults (n = 30) viewed pictures containing associatively related details. They viewed these pictures in pairs. Although the pictures differed, participants believed they had viewed the same pictures. Participants had to report what they could recollect during collaborative and individual recall tests. Children and adults were equally susceptible to memory conformity effects. When correcting for response bias, adults' false memory scores were even higher than children's. Our results show that age trends in suggestion-induced false memories are not developmentally invariant. (PsycINFO Database Record (c) 2017 APA, all rights reserved).

Voluntary Wheel Running Does not Affect Lipopolysaccharide-Induced Depressive-Like Behavior in Young Adult and Aged Mice

PubMed Central

Martin, Stephen A.; Dantzer, Robert; Kelley, Keith W.; Woods, Jeffrey A.

2014-01-01

Peripheral stimulation of the innate immune system with lipopolysaccharide (LPS) causes prolonged depressive-like behavior in aged mice that is dependent on indoleamine 2,3 dioxygenase (IDO) activation. Regular moderate intensity exercise training has been shown to exert neuroprotective effects that might reduce depressive-like behavior in aged mice. The purpose of this study was to test the hypothesis that voluntary wheel running would attenuate LPS-induced depressive-like behavior and brain IDO gene expression in 4-month-old and 22-month-old C57BL/6J mice. Mice were housed with a running wheel (Voluntary Wheel Running, VWR) or no wheel (Standard) for 30 days (young adult mice) or 70 days (aged mice), after which they were intraperitoneally injected with LPS (young adult mice: 0.83 mg/kg; aged mice: 0.33 mg/kg). Young adult VWR mice ran on average 6.9 km/day, while aged VWR mice ran on average 3.4 km/day. Both young adult and aged VWR mice increased their forced exercise tolerance compared to their respective Standard control groups. VWR had no effect on LPS-induced anorexia, weight-loss, increased immobility in the tail suspension test, and decreased sucrose preference in either young adult or aged mice. Four (young adult mice) and twenty-four (aged mice) hours after injection of LPS transcripts for TNF-α, IL-1β, IL-6, and IDO were upregulated in the whole brain independently of VWR. These results indicate that prolonged physical exercise has no effect on the neuroinflammatory response to LPS and its behavioral consequences. PMID:24281669

2015-01-01

Most research to date on implicit gender stereotyping has been conducted with one age group – young adults. The mechanisms that underlie the on-line processing of stereotypical information in other age groups have received very little attention. This is the first study to investigate real time processing of gender stereotypes at different age levels. We investigated the activation of gender stereotypes in Italian in four groups of participants: third- and fifth-graders, young and older adults. Participants heard a noun that was stereotypically associated with masculine (preside “headmaster”) or feminine roles (badante “social care worker”), followed by a male (padre “father”) or female kinship term (madre “mother”). The task was to decide if the two words – the role noun and the kinship term – could describe the same person. Across all age groups, participants were significantly faster to respond, and significantly more likely to press ‘yes,’ when the gender of the target was congruent with the stereotypical gender use of the preceding prime. These findings suggest that information about the stereotypical gender associated with a role noun is incorporated into the mental representation of this word and is activated as soon as the word is heard. In addition, our results show differences between male and female participants of the various age groups, and between male- and female-oriented stereotypes, pointing to important gender asymmetries.

The relationship between atherosclerosis and cognitive function is less well studied in Chinese populations. In addition, the results among middle-aged adults have been mixed. We aimed to investigate the association of atherosclerosis measured by carotid intima-media thickness (CIMT) and cognitive function in middle-aged and older adults from a Chinese community. Participants in the Asymptomatic Polyvascular Abnormalities in Community study (APAC) who had completed the CIMT detection and cognitive function measurements in 2012/2013 were included. Cognitive function was measured using the Mini-Mental State Examination (MMSE). Multivariate linear regression analysis was used to analyze the association between CIMT and MMSE. Then, a stratified analysis was performed separately in middle-aged and older adults. A total of 3227 participants were included in this study (mean age 57.9 years, range 43-93 years); 56.6 % of them were men, 66.0 % were middle-aged adults. After adjusting for potential confounders, larger CIMT was associated with lower MMSE scores, with a 0.75-point decrease in MMSE score for every 1-mm increase in CIMT (β = - 0.75, P = 0.0020). The association remained statistically significant in middle-aged adults (β = - 0.57, P = 0.0390), and was stronger in older adults and adults with low education levels. There is a significant association between CIMT and cognitive function among middle-aged and older adults sampled from a Chinese population. This association was stronger in older adults and adults with low education levels.

This study explored issues of culturally sensitive healthcare practice and needs among lesbian, gay, bisexual and transgender aging adults in coastal North Carolina. Survey data results indicated the largest problem was a history of verbally harassment and need for culturally sensitive healthcare. In conclusion, culturally sensitive interventions are needed to address the health disparities and unique needs of LGBT aging adults. Cultural sensitivity training for service providers is suggested as a vital step in addressing health disparities of aging LGBT adults. Implications for research include further exploration of health related needs of these often hidden and underserved population groups.

Many older people perceive ageing negatively, describing it in terms of poor or declining health and functioning. These perceptions may be related to older adults' health. The aim of this review was to synthesise existing research on the relationship between older adults' perceptions of ageing and their health and functioning. A systematic search was conducted of five electronic databases (ASSIA, CINAHL, IBSS, MEDLINE and PsycINFO). Citations within identified reports were also searched. Observational studies were included if they included perceptions of ageing and health-related measures involving participants aged 60 years and older. Study selection, data extraction and quality appraisal were conducted using predefined criteria. Twenty-eight reports met the criteria for inclusion. Older adults' perceptions of ageing were assessed with a variety of measures. Perceptions were related to health and functioning across seven health domains: memory and cognitive performance, physical and physiological performance, medical conditions and outcomes, disability, care-seeking, self-rated health, quality of life and death. How ageing is perceived by older adults is related to their health and functioning in multiple domains. However, higher quality and longitudinal studies are needed to further investigate this relationship.

Background. The incidence of inflammatory bowel disease (IBD) is increasing in the paediatric population. Since 2007, a single surgeon whose main practice is in the treatment of adults has performed surgery for IBD in adults and children within two dedicated multidisciplinary teams. Our aim was to assess and compare outcomes for adults and children following surgery for IBD. Methods. Analysis of a prospectively collected database was carried out to include all patients who had undergone resectional surgery for IBD between 2007 and 2012. Results. 48 adults and 30 children were included in the study. Median age for children was 14 years (range 8-16) and for adults was 33.5 years (range 17-64). Median BMI was 23 (range 18-38) and 19 (range 13-29.5) in adults and children, respectively (P < 0.001). Laparoscopic resection was performed in 27 (90%) children and 36 (75%) adults. Postoperative complication rates were comparable, 11 (23%) in adults versus 6 (20%) in children (P = 1.00). Conclusion. Resectional surgery for IBD in children has outcomes that compare favourably with the adult population, with the majority of cases being performed by a laparoscopic approach.

The objective of the present study was to verify how socioeconomic and physical/mental health status would be associated with activity limitations by age and sex among older adults, using nationally representative cross-sectional data in Japan. The present study focused on 8373 older adults aged 65 years or older extracted from the Comprehensive Survey of Living Conditions conducted in 2007 by the Japanese Ministry of Health, Labor and Welfare. Univariate and multiple logistic regression analyses and population-attributable risk were applied to validate the relationships of socioeconomic and physical/mental health status with activity limitations among the total population, and by age groups (young-old or old-old) and sex. Mental health showed the highest odds ratio and population-attributable risk in the total population. In addition, low back pain was associated with activity limitations regardless of age and sex. Other musculoskeletal diseases, such as arthropathy and osteoporosis, were related to activity limitations for women, regardless of age, whereas cardiovascular diseases, including angina pectoris/myocardial infarction and cerebral stroke, were associated with activity limitations for men in any age group. There were no statistically significant correlations between socioeconomic status and activity limitations in any groups. Mental health was the most important factor of activity limitations in Japanese older adults. Furthermore, low back pain regardless of age and sex, other musculoskeletal diseases only for women and cardiovascular diseases mainly for men could also be significant risk factors to activity limitations. Therefore, preventive approaches of activity limitations considering sex differences are important for older adults in Japan. Geriatr Gerontol Int 2015; ●●: ●●-●●. © 2015 Japan Geriatrics Society.

Davitt, Joan K; Madigan, Elizabeth A; Rantz, Marilyn; Skemp, Lisa

2016-01-01

Public health advances have contributed to increased longevity; however, individuals are more likely to live longer with multiple chronic conditions. The existing health care system primarily focuses on treating disease rather than addressing well-being as a holistic construct that includes physical, social, and environmental components. The current commentary emphasizes the importance of supporting healthy active aging and aging in community. The barriers to aging in community and the state of the intervention science in response to this problem are discussed, and recommendations for future research are provided. Active aging is more than managing illness or care transitions-it promotes engagement, participation, dignity, self-fulfillment, self-determination, and support for older adults. To support aging in community and healthy active aging, a paradigm shift is needed in how the well-being of older adults is thought about and supported. Copyright 2016, SLACK Incorporated.

Confucian Values as a Buffer Against Age-Based Stereotype Threat for Chinese Older Adults.

Research has shown that stereotype threat can impair older adults' memory in Western cultures. We tested whether this also occurs for older adults from the East Asian Chinese culture. We also tested whether an intervention that highlighted Confucian principles would protect Chinese older adults from stereotype threat's detrimental effects. Culturally-Chinese older adults residing in the United States completed a memory test either under age-based stereotype threat about cognitive decline or not. Prior to this, some participants were also reminded of Confucian traditions of filial piety and were assured these values had been transmitted to the younger generation. Stereotype threat impaired Chinese older adults' memory performance. However, our intervention was effective in eliminating this deficit. When the Chinese participants were reminded of the Confucian principle of filial piety they did not exhibit stereotype threat effects. Confirming that younger adults have an obligation to respect their elders can eliminate the social-evaluative pressure of stereotype threat for Chinese older adults. These findings are noteworthy since population aging is happening at an unprecedented pace in East Asia. Although our results suggest that stereotype threat can adversely affect older adults' cognitive performance in these societies, we also identify a culturally-based intervention to alleviate this impairment.

Background: Limitations in spinal mobility can interfere with the attainment of important functional skills and activities of daily living and restrictions in spinal mobility are usually the earliest and reliable indicator of diseases. Objective: The aim of this study was to determine the differences of lumbar spinal mobility among healthy adults with advancing age. Materials and Methods: The modified Schober's method was used to measure anterior flexion. The guideline of the American Academy of Orthopaedic Surgeons was adapted to measure lateral flexion and extension. Results: The results of this study indicate that spinal mobility decreases with advancing age. The most significant (P < 0.05) differences occurred between the two youngest and the two oldest age categories. Conclusion: Using these data, we developed normative values of spinal mobility for each sex and age group. This study helps the clinicians to understand and correlate the restrictions of lumbar spinal mobility due to age and differentiate the limitations due to disease. PMID:22408334

Handwriting is an important activity that is commonly affected by neurological and orthopaedic conditions. Handwriting research has predominantly involved children. Little is known about handwriting behaviour in healthy older adults. This study aims to describe the handwriting practices of 30 unimpaired adults aged 65 years and over. In this cross-sectional observational study, data were collected from 30 older adults using a self-report questionnaire, digital pen recordings over three days and a handwriting log. Data were analysed using descriptive statistics. The mean age of participants was 75.1 years (standard deviation=6.9). Variations in handwriting were evident in letter size, slant and spacing. Participants wrote very little--a median of 18 words per occasion (interquartile range=10.5-26.9 words). Most handwriting involved self-generated text (85%), not copied or transcribed text. Participants stood while writing for 17% of handwriting occasions. The most common reasons for handwriting were note taking (23%) and puzzles (22%). Legibility may not depend exclusively on the handwriting script that a beginning writer is taught, but may be a result of other factors as the person ages. A comprehensive adult handwriting assessment and retraining programme should be relevant to older adults, including common handwriting activities, involving self-generated text and few words. © 2011 The Authors.

The present study investigated the effects of grip on changes in the median nerve cross-sectional area (MNCSA) and median nerve diameter in the radial-ulnar direction (D1) and dorsal-palmar direction (D2) at three wrist angles. Twenty-nine healthy participants (19 men [mean age, 24.2 ± 1.6 years]; 10 women [mean age, 24.0 ± 1.6 years]) were recruited. The median nerve was examined at the proximal carpal tunnel region in three grip conditions, namely finger relaxation, unclenched fist, and clenched fist. Ultrasound examinations were performed in the neutral wrist position (0°), at 30°wrist flexion, and at 30°wrist extension for both wrists. The grip condition and wrist angle showed significant main effects (p < 0.01) on the changes in the MNCSA, D1, and D2. Furthermore, significant interactions (p < 0.01) were found between the grip condition and wrist angle for the MNCSA, D1, and D2. In the neutral wrist position (0°), significant reductions in the MNCSA, D1, and D2 were observed when finger relaxation changed to unclenched fist and clenched fist conditions. Clenched fist condition caused the highest deformations in the median nerve measurements (MNCSA, approximately −25%; D1, −13%; D2, −12%). The MNCSA was significantly lower at 30°wrist flexion and 30°wrist extension than in the neutral wrist position (0°) at unclenched fist and clenched fist conditions. Notably, clenched fist condition at 30°wrist flexion showed the highest reduction of the MNCSA (−29%). In addition, 30°wrist flexion resulted in a lower D1 at clenched fist condition. In contrast, 30°wrist extension resulted in a lower D2 at both unclenched fist and clenched fist conditions. Our results suggest that unclenched fist and clenched fist conditions cause reductions in the MNCSA, D1, and D2. More importantly, unclenched fist and clenched fist conditions at 30°wrist flexion and 30°wrist extension can lead to further deformation of the median nerve. PMID:27688983

Background: being unmarried is associated with worse health and increased mortality risk. Telomere length has emerged as a marker for biological ageing but it is unclear how telomere length relates to marital status. Objective: to examine the relationship between telomere length and marital status in a sample of middle-aged adults. Design and subjects: cross-sectional analysis among 321 adults aged 40–64 years. Methods: telomere length was measured by PCR (T/S ratio). Participants provided information on healthy lifestyle activities including smoking, alcohol use, diet, exercise, obesity as well as social support. Results: participants married or living with a partner had a mean T/S ratio of 1.70 and those widowed, divorced, separated or never married had a mean T/S ratio of 1.58 in a model adjusted for age, gender and race/ethnicity (P < 0.001). When the analysis was further adjusted for diet, alcohol consumption, exercise, smoking, social support, poverty and obesity, persons married or living with a partner had a higher mean T/S ratio of 1.69 than their unmarried counterparts (1.59) (P = 0.004). Conclusions: these results indicate that unmarried individuals have shorter telomeres. This relationship between marital status and telomere length is independent of presumed benefits of marriage such as social support and a healthier lifestyle. PMID:20817935

Safety and efficacy data on pegylated asparaginase (PEG-ASP) in adult acute lymphoblastic leukaemia (ALL) induction regimens are limited. The UK National Cancer Research Institute UKALL14 trial NCT01085617 prospectively evaluated the tolerability of 1000 IU/m 2 PEG-ASP administered on days 4 and 18 as part of a five-drug induction regimen in adults aged 25-65 years with de novo ALL. Median age was 46.5 years. Sixteen of the 90 patients (median age 56 years) suffered treatment-related mortality during initial induction therapy. Eight of the 16 died of sepsis in combination with hepatotoxicity. Age and Philadelphia (Ph) status were independent variables predicting induction death >40 versus ⩽40 years, odds ratio (OR) 18.5 (2.02-169.0), P=0.01; Ph- versus Ph+ disease, OR 13.60 (3.52-52.36), P<0.001. Of the 74 patients who did not die, 37 (50.0%) experienced at least one grade 3/4 PEG-ASP-related adverse event, most commonly hepatotoxicity (36.5%, n=27). A single dose of PEG-ASP achieved trough therapeutic enzyme levels in 42/49 (86%) of the patients tested. Although PEG-ASP delivered prolonged asparaginase activity in adults, it was difficult to administer safely as part of the UKALL14 intensive multiagent regimen to those aged >40 years. It proved extremely toxic in patients with Ph+ ALL, possibly owing to interaction with imatinib.
