    Adult T-cell leukemia-lymphoma is a distinct type of peripheral T-cell lymphoma caused by human T-cell lymphotropic virus type I. Although allogeneic stem cell transplantation after chemotherapy is a recommended treatment option for patients with aggressive adult T-cell leukemia-lymphoma, there is no consensus about indications for allogeneic stem cell transplantation because there is no established risk stratification system for transplant eligible patients. We conducted a nationwide survey of patients with aggressive adult T-cell leukemia-lymphoma in order to construct a new, large database that includes 1,792 patients aged 70 years or younger with aggressive adult T-cell leukemia-lymphoma who were diagnosed between 2000 and 2013 and received intensive first-line chemotherapy. We randomly divided patients into two groups (training and validation sets). Acute type, poor performance status, high soluble interleukin-2 receptor levels (> 5,000 U/mL), high adjusted calcium levels (≥ 12 mg/dL), and high C-reactive protein levels (≥ 2.5 mg/dL) were independent adverse prognostic factors used in the training set. We used these five variables to divide patients into three risk groups. In the validation set, median overall survival for the low-, intermediate-, and high-risk groups was 626 days, 322 days, and 197 days, respectively. In the intermediate- and high-risk groups, transplanted recipients had significantly better overall survival than non-transplanted patients. We developed a promising new risk stratification system to identify patients aged 70 years or younger with aggressive adult T-cell leukemia-lymphoma who may benefit from upfront allogeneic stem cell transplantation. Prospective studies are warranted to confirm the benefit of this treatment strategy. Copyright© 2017 Ferrata Storti Foundation.

    Full Text Available The main objective of this research is to determine developmental characteristics of dynamic drawings of preschool and younger school age children. The sample consists of 90 typical developed children, aged between 6 and 9. The sample includes 47 (52.2% girls and 43 (47.8% boys from preschool institutions and elementary schools in Pirot and Belgrade. Action representation in dynamic drawings was evaluated using three types of drawings: a man who runs, a man shooting a ball and a man lifting a ball from the floor. We determined that a very small number of the respondents reaches the highest level of graphical representation of figures in motion, and that girl’s achievements are better than boy’s achievements. However, this result is on the border of statistical significance (p=0.052. Also, there is a statistically significant trend of progress to higher levels of action representation (p=0.000 with the increase in chronological age of the respondents.

    Infliximab (IFX) is efficacious for induction and maintenance of remission in pediatric patients with moderate-to-severe inflammatory bowel disease (IBD). It has, however, not been studied in patients 7 years old and younger. Our aim was to characterize efficacy and safety of IFX therapy in this cohort. This was a retrospective study of patients with IBD ages 7 years and younger, treated with IFX between 1999 and 2011. Medical records were reviewed for age of diagnosis, disease phenotype, therapy, surgery, IFX infusion dates, dose, and intervals. Outcome measures included physician global assessment, corticosteroid requirement, and adverse events. Thirty-three children (ages 2.4-7 years) were included. Twenty patients had Crohn disease, 4 had ulcerative colitis, and 9 had indeterminate colitis. Maintenance of IFX therapy at 1, 2, and 3 years was 36%, 18%, and 12%, respectively. Patients of age 5 years and younger had the lowest rates of maintenance of therapy at 25% at year 1, and 10% at years 2 and 3 combined. Nine percent of all of the patients demonstrated response measured by the physician global assessment and were steroid free at 1 year. There were 8 infusion reactions. There were no malignancies, serious infections, or deaths. IFX demonstrated a modest response rate and a low steroid-sparing effect in patients with IBD 7 years old and younger. Although this is a limited study, there appears to be a trend for decreased sustained efficacy with IFX in this age group, particularly in children 5 years old and younger, when compared with the previously published literature in older children.

    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

    Resistant hypertension, defined as blood pressure >140/90 mm Hg despite using ≥3 antihypertensive medications, is a well-recognized clinical entity. Patients with resistant hypertension are at an increased risk of cardiovascular disease compared with those with more easily controlled hypertension. Coronary heart disease mortality rates of younger adults are stagnating or on the rise. The purpose of our study was to characterize the phenotype and risk factors of younger patients with resistant hypertension, given the dearth of data on cardiovascular risk profile in this cohort. We conducted a cross-sectional analysis with predefined age groups of a large, ethnically diverse cohort of 2170 patients referred to the Hypertension Clinic at the University of Alabama at Birmingham. Patients (n=2068) met the inclusion criteria and were classified by age groups, that is, ≤40 years (12.7% of total cohort), 41 to 55 years (32.1%), 56 to 70 years (36.1%), and ≥71 years (19.1%). Patients aged ≤40 years compared with those aged ≥71 years had significantly earlier onset of hypertension (24.7±7.4 versus 55.0±14.1 years; P hypertension, younger individuals have a distinct phenotype characterized by overlapping risk factors and comorbidities, including obesity, high aldosterone, and high dietary sodium intake compared with elderly. © 2017 American Heart Association, Inc.

  8. Types of phone usage: Age differences between younger and older persons

    Full Text Available I Even if more and more people use mobile phones, the gap between younger and older age groups persists and its importance is timely and widened given the present ageing and digital inequality phenomena. How wide is the difference on types of phone usage between different age groups? For answering this research question, we employ binary logistic regressions on several types of phone usage keeping into account age and controlling for region, education, income and whether respondents use a feature phone or a smartphone. The analysed data come from the Spring Change Assessment Survey 2010 provided by the Pew Research Center and it is representative for the United States of America. Our results show that, net of the all the variables included in the model, older persons are less likely than younger persons to use such phone functions, but the strength of association is low. Education and income are relevant for these functions. Using a smartphone in comparison with using a feature phone is important in all the situations included, as well as income. Considering models only for older persons, over 65 years of age, college and income are less relevant. Using a smartphone is more likely than using a feature phone to encourage all types of phone usage, independently of age.

    The study's objective was to summarize the psychometric evaluation of self-report symptom instruments used in children with cancer younger than 8 years of age. We conducted electronic searches of Ovid Medline, EMBASE, PsycInfo, Science Citation, Social Science Citation (Web of Science), and CINAHL. We included studies of children with cancer in which their self-report symptoms had been quantified and in which results were described for those younger than 8 years of age. The search was restricted to publications in English. Two reviewers screened studies and abstracted all data in duplicate. Descriptive analysis of reliability and validity was performed. Thirteen studies were included. Only one study recruited children report symptoms are reliable or valid specifically for children with cancer younger than 8 years of age. Development of psychometrically robust instruments for younger children should be a priority.

    Destination memory, a memory component allowing the attribution of information to its appropriate receiver (e.g., to whom did I lend my pen?), is compromised in normal aging. The present paper investigated whether older adults might show better memory for older destinations than for younger destinations. This hypothesis is based on empirical research showing better memory for older faces than for younger faces in older adults. Forty-one older adults and 44 younger adults were asked to tell proverbs to older and younger destinations (i.e., coloured faces). On a later recognition test, participants had to decide whether they had previously told some proverb to an older/younger destination or not. Prior to this task, participants reported their frequency of contact with other-age groups. The results showed lower destination memory in older adults than in younger adults. Interestingly, older adults displayed better memory for older than for younger destinations. The opposite pattern was seen in younger adults. The low memory for younger destinations, as observed in older adults, was significantly correlated with limited exposure to younger individuals. These findings suggest that for older adults, the social experience can play a crucial role in the destination memory, at least as far as exposure to other-age groups is concerned.

    Full Text Available The use of antipsychotics in very young children is of concern given the lack of empirical evidence in their efficacy and long-term impact on children’s health. This study examined the prescription of antipsychotics among children aged ≤5 years enrolled in a state Medicaid program. Secondary data analysis was conducted using the Medicaid administrative data of a southeastern state. Using SAS 9.3, descriptive statistics were performed to examine socio-demographic characteristics, psychiatric diagnoses, off-label use, receipt of medications from multiple psychotropic drug classes, and receipt of non-pharmacologic psychiatric services among children aged ≤5 years who received antipsychotic prescriptions in calendar year (CY 2011. A total of 112 children in the target age group received antipsychotics in CY 2011, the most common prescription being risperidone. The most common listed psychiatric diagnosis was attention deficit hyperactivity disorder. Two in five children received antipsychotics for off-label use. Three in four children also received medications from at least one other psychotropic drug class. More than half did not receive adjunct psychiatric services. State-level policies offering specific guidance and recommendations for antipsychotic use among very young children are urgently needed. Future research is warranted to examine long-term impact of such practices on children’s growth and development.

  14. WAYFINDING STUDY IN VIRTUAL ENVIRONMENTS: THE ELDERLY VS. THE YOUNGER-AGED GROUPS

    Full Text Available This study aims to examine the impact of architectural wayfinding aids on wayfinding performances in comparison of the elderly group and the younger aged group. An ambulatory healthcare facility was simulated using Virtual Reality (VR to develop two levels of wayfinding aids for the same environments. The base model included minimal wayfinding aids, and the design model included more wayfinding aids. The VR environment was presented in the form of video in order to test wayfinding performances at three different wayfinding decision points. Results showed that age and wayfinding aids impacted wayfinding performances. The younger-aged group performed wayfinding better compared to the elderly group. Participants who were tested in the design model were more successful in wayfinding compared to the elderly group. The elderly group reported that more salient wayfinding aids such as a big logo and paint colors helped their wayfinding while the younger-aged group reported less salient aids such as door designs as helpful wayfinding aids. When there were minimal wayfinding aids, the elderly participants needed to rely mostly on memory recall by remembering turns or paying close attention. When participants felt that the wayfinding test was difficult, their performances were less successful. Findings in this study suggest that wayfinding design for the elderly should consider the limited ability of recall and therefore, design wayfinding aids more frequently with more salient aids to avoid confusion. The elderly group needed to rely on their limited cognitive ability when there were not enough wayfinding aids, which make them experience difficulties in wayfinding.

    Endoscopic third ventriculostomy (ETV) is a valuable option in the treatment of shunt failure, but no clinical data exist for young children. The aim of this study was to elucidate the role of ETV in patients younger than 3 years of age with shunt malfunction. A cohort of 37 patients younger than 3 years of age with shunt malfunction underwent ETV instead of shunt revision. Patients' preoperative condition and medical history were studied to determine the impact of a number of variables on outcome. The Fisher exact test was used to assess differences among groups. Median age at ETV was 21.6 months (8-36 months). Diagnosis was obstructive hydrocephalus in 24 patients and communicating hydrocephalus in 13. Median age at initial shunt placement was 3.2 months (10 days to 30 months). The etiology of shunt malfunction was obstruction (n = 27) or infection (n = 10). Overall ETV failure rate was 40.5% (15/37). Patients whose age at initial shunt placement was <6 months and/or who had a preterm birth history had higher relative rates of ETV failure. Other variables, including type of hydrocephalus, interval between initial shunt placement and ETV, history of intraventricular bleeding and/or infection, and etiology of shunt malfunction, did not significantly affect the final outcome. Patients younger than 3 years with obstructive or communicating hydrocephalus may benefit from ETV in the event of shunt malfunction and have about a 60% probability of becoming shunt free.

    2006-01-01

    Full Text Available The paper deals with the importance of play for children’s development and learning in institutionalized preschool education, as well as the opportunities it provides concerning the organization of teaching activities with younger school age children. The paper is based on the theoretical framework emphasizing educational character of children’s play, as a specific form of learning. Notwithstanding occasional attempts within pedagogic theory to deny educational values of children’s play and to emphasize instruction as the only form of systematic learning, contemporary pedagogic views consider play an important part of school education. Learning through play at younger school age helps overcome the discontinuity between preschool and school education. Curriculum subject matter can be covered through carefully selected and prepared play activities within the existing system, providing the support, encouragement and guidance by the adults involved, including their proper knowledge of children’ age-related and psycho-physical characteristics. Play facilitates gradual change over from preschool to school developmental stage, free, spontaneous and creative expression and the development of children’s potential.

    Introduction Medical cannabis is increasingly being used for a variety of health conditions as more states implement legislation permitting medical use of cannabis. Little is known about medical cannabis use patterns and motives among adults across the lifespan. Methods The present study examined data collected at a medical cannabis dispensary in San Francisco, California. Participants included 217 medical cannabis patients who were grouped into age-defined cohorts (younger: 18–30, middle-aged: 31–50, and older: 51–72). The age groups were compared on several measures of cannabis use, motives and medical conditions using one-way ANOVAs, chi-square tests and linear regression analyses. Results All three age groups had similar frequency of cannabis use over the past month; however, the quantity of cannabis used and rates of problematic cannabis use were higher among younger users relative to middle-aged and older adults. The association between age and problematic cannabis use was moderated by age of regular use initiation such that earlier age of regular cannabis use onset was associated with more problematic use in the younger users, but not among older users. Middle-aged adults were more likely to report using medical cannabis for insomnia, while older adults were more likely to use medical cannabis for chronic medical problems such as cancer, glaucoma and HIV/AIDS. Younger participants reported cannabis use when bored at a greater rate than middle-aged and older adults. Conclusions Findings suggest that there is an age-related risk for problematic cannabis use among medical cannabis users, such that younger users should be monitored for cannabis use patterns that may lead to deleterious consequences.

    To assess the practicality and benefit of Bone-anchored hearing aid (BAHA(®)) implantation in children younger than 5 years of age. FDA approval for use of BAHA(®) only exists for children 5 years of age and older. Their use in Australia is also rare, however their use for younger children is approved by the European Union. We wish to share our experience of implantation in an antipodean setting in this age group. Institutional board approval was obtained for this study. All children undergoing BAHA(®) implantation under 5 years old were included from our prospective database. We examined the variety of surgical techniques, (including skin grafting, limited soft tissue reduction and no soft tissue reduction), BAHA(®) implants and abutments used, and use of the new series 400 hydroxyapatite coatings. Demographic data obtained included age at surgery, follow up duration, gender, ethnicity and indication for surgery. Anonymous benefit questionnaires (Glasgow children's benefit inventory (GCBI) and parents' evaluation of aural performance of children (PEACH)) were completed online as well as a questionnaire on device use. Complications recorded included soft tissue reactions, implant loss/removal, abutment replacement/removal. We also assessed whether patient weight, ethnicity or socioeconomic status were risk factors for these complications. 24 Children (26 ears/26 implants) under five years were identified from the database and included in the study. There was a 14:10 male to female ratio. Patient caregivers reported subjective benefit and improved quality of life (QOL) despite setbacks and complications related to BAHA(®) usage. 10/24 (42%) of children required treatment for significant peri-implant skin reactions whilst 25% required replacement of their abutments and/or implants. An increased risk of major complication was associated with socioeconomic deprived backgrounds and in patients of New Zealand Maori and Pacific Island ethnicity but not in patients

    IMPORTANCE Young febrile infants are at substantial risk of serious bacterial infections; however, the current culture-based diagnosis has limitations. Analysis of host expression patterns (“RNA biosignatures”) in response to infections may provide an alternative diagnostic approach. OBJECTIVE To assess whether RNA biosignatures can distinguish febrile infants aged 60 days or younger with and without serious bacterial infections. DESIGN, SETTING, AND PARTICIPANTS Prospective observational study involving a convenience sample of febrile infants 60 days or younger evaluated for fever (temperature >38° C) in 22 emergency departments from December 2008 to December 2010 who underwent laboratory evaluations including blood cultures. A random sample of infants with and without bacterial infections was selected for RNA biosignature analysis. Afebrile healthy infants served as controls. Blood samples were collected for cultures and RNA biosignatures. Bioinformatics tools were applied to define RNA biosignatures to classify febrile infants by infection type. EXPOSURE RNA biosignatures compared with cultures for discriminating febrile infants with and without bacterial infections and infants with bacteremia from those without bacterial infections. MAIN OUTCOMES AND MEASURES Bacterial infection confirmed by culture. Performance of RNA biosignatures was compared with routine laboratory screening tests and Yale Observation Scale (YOS) scores. RESULTS Of 1883 febrile infants (median age, 37 days; 55.7%boys), RNA biosignatures were measured in 279 randomly selected infants (89 with bacterial infections—including 32 with bacteremia and 15 with urinary tract infections—and 190 without bacterial infections), and 19 afebrile healthy infants. Sixty-six classifier genes were identified that distinguished infants with and without bacterial infections in the test set with 87%(95%CI, 73%-95%) sensitivity and 89% (95%CI, 81%-93%) specificity.

    Voriconazole is used for treating or preventing invasive aspergillosis and other invasive fungal infections. To minimize adverse reactions and to maximize treatment effects, therapeutic drug monitoring should be performed. However, it is challenging to optimize daily voriconazole dosing because limited data have been published so far on pediatric patients. We retrospectively analyzed voriconazole concentrations in patients aged 0-18 years. In addition, a literature review was conducted. In our study cohort, younger age and oral administration were significantly associated with lower plasma voriconazole concentrations (P voriconazole (P = 0.01). Reports of voriconazole administration in pediatric patients show that higher doses are required in younger children and in patients receiving oral administration. Hence, the current data suggest that we should escalate both initial and maintenance doses of voriconazole in pediatric patients, particularly in patients of younger age receiving an oral administration of voriconazole.

    Full Text Available The late-glacial Younger Dryas Stadial, as defined over seventy years ago in Denmark, was compared with the withdrawal of the Scandinavian ice sheet and correlated in Finland in 1951 with the formation of the Salpausselkä moraines. Since then a great number of studies of Younger Dryas has eventually led to its definition in the Event Stratigraphy for the North Atlantic region, based on the oxygen isotope stratigraphy in the Greenland ice-core NGRIP. The age of the Younger Dryas / Preboreal boundary, the beginning of the Holocene, is in this stratigraphy dated at 11 653 yr. BP, an age close to the age deter-mined for the drainage of the Baltic Ice Lake and the beginning of the rapid retreat of the ice margin from Salpausselkä II in Finland and the corresponding Billingen moraine in Sweden. This leads to the conclusion that the Salpausselkä moraines Ss I and Ss II were formed during Younger Dryas, according to the revised varve chronology between c. 12 260 and c. 11 600 yr. BP. The third Salpausselkä, Ss III, was according to this dating formed in early Holocene. After the 1950s, when the Salpausselkä moraines were dated as having been formed during the Younger Dryas Stadial, the ages of the boundaries of Younger Dryas changed as a result of revisions of the time scales of varved clays and the use of radiocarbon ages and their calibrations. As a result of these changes the age of the two main Salpausselkä moraines, Ss I and Ss II, is older than assumed 60 years ago on the basis of the varve chronology.

    The debate continues as to whether younger women who present with breast cancer have a more aggressive form of disease and a worse prognosis. The objectives of this study were to determine the incidence of breast cancer in women under 40 years old and to analyse the clinicopathological characteristics and outcome compared to an older patient cohort. Data was acquired from a review of charts and the prospectively reviewed GUH Department of Surgery database. Included in the study were 276 women diagnosed with breast cancer under the age of forty and 2869 women over forty. For survival analysis each women less than 40 was matched with two women over forty for both disease stage and grade. The proportion of women diagnosed with breast cancer under the age of forty in our cohort was 8.8%. In comparison to their older counterparts, those under forty had a higher tumour grade (p = 0.044) and stage (p = 0.046), a lower incidence of lobular tumours (p < 0.001), higher estrogen receptor negativity (p < 0.001) and higher HER2 over-expression (p = 0.002); there was no statistical difference as regards tumour size (p = 0.477). There was no significant difference in overall survival (OS) for both groups; and factors like tumour size (p = 0.026), invasion (p = 0.026) and histological type (p = 0.027), PR (p = 0.031) and HER2 (p = 0.002) status and treatment received were independent predictors of OS Breast cancer in younger women has distinct histopathological characteristics; however, this does not result in a reduced survival in this population

    Full Text Available The ability to understand the meaning of words and sentences is an important determinant of the language development, which also indicates the development of the ability to learn. Bearing this in mind, the research was aimed at studying the level of semantic development of younger primary school-age children. Semantic development was studied from the aspect of understanding the meaning of words and their use in the following lexical relations: homonyms, antonyms, synonyms and metonyms. The research was conducted in three Belgrade primary schools during the school year 2013/2014. The sample was convenient and included 431 second- and third-grade pupils. The Semantic test (by S. Vladisavljevic was used in the study. Research results showed that none of the pupils had provided the correct answer to all administered tasks. The best scores were achieved on the part of the test referring to antonyms, while the pupils were least successful on the tasks referring to metonyms. Additionally, third-grade pupils were more successful than younger participants, while there were no differences according to gender. The results indicated that it was necessary to devote more attention to different lexical and semantic exercises at preschool and early school age, considering the link between semantic development, the acquisition of reading and writing skills and the (unsuccessful mastering of the school curriculum in the majority of subjects.

    Traditionally regarded as a disease of the elderly, the incidence of diverticulitis of the colon has been on the rise, especially in younger cohorts. These patients have been found to experience a more aggressive disease course with more frequent hospitalization and greater need for surgical intervention. To characterize factors that portend a poor prognosis in patients diagnosed with diverticulitis; in particular, to evaluate the role of demographic variables on disease course. Using the Canadian Institute for Health Information Discharge Abstract Databases, readmission rates, length of stay, colectomy rates and mortality rates in patients hospitalized for diverticulitis were examined. Data were stratified according to age, sex and comorbidity (as defined by the Charlson index). In the cohort ≤30 years of age, a clear male predominance was apparent. Colectomy rate in the index admission, stratified according to age, demonstrated a J-shaped curve, with the highest rate in patients ≤30 years of age (adjusted OR 2.3 [95% CI 1.62 to 3.27]) compared with the 31 to 40 years of age group. In-hospital mortality increased with age. Cumulative rates of readmission at six and 12 months were 6.8% and 8.8%, respectively. In the present nationwide cohort study, younger patients (specifically those ≤30 years of age) were at highest risk for colectomy during their index admission for diverticulitis. It is unclear whether this observation was due to more virulent disease among younger patients, or surgeon and patient preferences.

  10. Younger age at onset of sporadic Parkinson’s disease among subjects occupationally exposed to metals and pesticides

    Full Text Available An earlier age at onset of Parkinson’s disease (PD has been reported to be associated with occupational exposures to manganese and hydrocarbon solvents suggesting that exposure to neurotoxic chemicals may hasten the progression of idiopathic PD. In this study the role of occupational exposure to metals and pesticides in the progression of idiopathic PD was assessed by looking at age at disease onset. The effects of heritable genetic risk factors, which may also influence age at onset, was minimized by including only sporadic cases of PD with no family history of the disease (n=58. Independent samples Student t-test revealed that subjects with occupational exposure to metals and/or pesticides (n=36 were significantly (p=0.013 younger than unexposed controls (n=22. These subjects were then divided into three groups [high (n=18, low (n=18, and unexposed (n=22] to ascertain if duration of exposure further influenced age at onset of PD. One-way ANOVA revealed that subjects in the high exposure group were significantly (p=0.0121 younger (mean age: 50.33 years than unexposed subjects (mean age: 60.45 years. Subjects were also stratified by exposure type (metals vs. pesticides. These results suggest that chronic exposure to metals and pesticides is associated with a younger age at onset of PD among patients with no family history of the disease and that duration of exposure is a factor in the magnitude of this effect.

    Perceptions of disease risk play an important role in motivating people to adopt healthy behaviors. However, little is known about psychosocial factors that influence women's perceived risk for developing disease. The present study investigated the extent to which individual traits, social influences, objective risk factors, and demographic characteristics were associated with women's risk perceptions for cardiovascular disease, breast cancer, and lung cancer. Using structural equation modeling, we examined hypothesized associations among 452 younger (ages 18-25 years) and 167 middle-aged (ages 40-64 years) women. A greater number and variety of factors were associated with middle-aged women's risk perceptions compared to younger women. For both groups, some objective risk factors were associated with risk perceptions; yet, associations also existed between multiple psychosocial variables (optimism, health locus of control, social exposure to disease, perceived stigma) and risk perceptions. Results suggested that women may base their risk estimates on factors beyond those considered important by healthcare providers.

    Femoral neck stress fractures are rare in healthy children, with only 9 cases previously reported. The present article reviews our institutional experience with femoral neck stress fractures in children younger than 10 years of age, to highlight the unique features of this condition. We undertook a retrospective review of clinical records of patients who had been treated at our institution for an idiopathic femoral neck stress fracture between 2000 and 2014. To focus on children rather than adolescents, the World Health Organization's definition of adolescent as a person between 10 and 19 years of age was used; we thereby limited our analysis to patients younger than 10 years of age. The study included 6 patients (3 males, 3 females) treated for an idiopathic femoral neck stress fracture, with a mean age at diagnosis of 7.7 years (range, 5.2 to 8.9 y). All patients presented with a limp, which worsened with activity and had persisted for a mean of 5 weeks (range, 2 to 9 wk). None of the patients had experienced an increase in activity level or sporting volume before symptom onset. On examination, 3 patients experienced pain with terminal hip flexion and 3 patients demonstrated pain-free hip range of motion. Plain radiography demonstrated inferior femoral neck cortical disruption, suggesting a compression-type stress fracture mechanism. The diagnosis was confirmed by cross-sectional imaging in all cases. All patients were initially treated with 6 to 8 weeks of non-weight-bearing followed by 4 to 6 weeks of partial weight-bearing, leading to complete healing in 4 patients. Two patients demonstrated incomplete healing and were managed with spica casting for an additional 6 weeks. Our case series illustrates the unique features of this rare condition in children, with a history and examination profile distinct from those of adolescents and adults. Compliance with weight-bearing restrictions is difficult in this population and hip spica casting may be required to permit

    To determine the age distribution of children with Coats disease and the impact of age at diagnosis on the visual prognosis. Consecutive Coats disease cases aged 18 years or younger at diagnosis were retrospectively included. Clinical and imaging parameters were analyzed by comparative, correlation, survival, univariate, and multivariate statistics. Ninety-eight patients were included. At diagnosis, mean age was 5.4 years ± 4.3 years (1 month-18 years). Younger age at diagnosis was correlated with more severe disease stage (P presentation in patients younger than 4 years (P presentation in younger than older patients (P = 0.0003 and P = 0.039). Foveal sparing at diagnosis was less frequent in younger than older patients (2% vs. 23%, P = 0.002). The incidence of structural complications or enucleation during follow-up (mean duration: 5.9 years ± 4.5 years) was higher, and last-recorded visual acuity was lower in younger than older patients (P = 0.001 and P = 0.0009). Final logarithm of the minimal angle of resolution visual acuity was negatively correlated with age at diagnosis (P = 0.001, Spearman r = -0.42). Multivariate analysis indicated that disease stage (P visual acuity. Onset of Coats disease in children of younger age is associated with more severe manifestations, more advanced stage, and worse visual outcome. Age, correlated with disease stage, should be considered a prognostic marker in Coats disease.

    Full Text Available Few studies examining the clinical features and gene mutations in lung cancer patients 30 years of age or younger have been published. A trend towards increasing morbidity has been noted in young patients; thus, an urgent need exists to explore this subgroup of patients.Patients aged ≤30 years with pathologically diagnosed lung cancer were retrospectively evaluated. We reviewed the clinical features, gene mutations and prognosis of each patient.Forty-one patients were included in this study. The mean age was 26.4±3.5 years. Cough, tightness/dyspnea and chest pain were common symptoms, and 58.5% of patients presented with advanced stages of lung cancer. Adenocarcinoma was the predominant histologic type noted in these young patients. Masses and nodules were the dominant imaging features observed upon lung computed tomography (CT. Thoracic lymphadenopathy occurred very frequently in these patients. Five of 6 patients with echinoderm microtubule-associated protein-like 4 (EML4-anaplastic lymphoma kinase (ALK gene fusions presented solid masses with no ground-glass opacity (GGO and thoracic multifocal lymphadenopathy. Six of 22 (27.2% cases contained EML4-ALK gene fusions. In addition, 5 of 22 (22.7% patients harbored epidermal growth factor receptor (EGFR mutations, and 2 of 17 patients exhibited KRAS and ROS1 gene mutations. The median survival times were 44.2 months for patients with early stage disease and 8 months for patients with advanced NSCLC disease. The one-year and 5-year survival rates were 56.6% and 38.6%, respectively.Increased gene mutation frequencies are noted in these very young lung cancer patients. This finding indicates that the detection of gene mutations in these patients is important and will help to determine the appropriate targeted therapy.

    The prevalence of bullying among children, and the sometimes tragic consequences as a result, has become a major concern in schools. The larger research for this study reported on in-depth interviews with 28 elementary and middle school-age boys and girls (7–12 years) who had experienced various forms of bullying and relational aggression by their peers, mostly on school grounds, and the responses of their parents and teachers. Responses of the children's teen siblings to the younger child's revelations of being bullied are the focus of this report. In-depth interviews with each teen sibling (n = 28) and with each bullied child revealed how the children viewed the teen siblings' supportive strategies. Almost all the children (89%) reported that their older siblings talked with them and offered advice. The teen siblings shared with the younger ones that they too (71%) had been bullied, or they knew someone who had been bullied (18%). Teens gave the advice to ‘bully back’ to 11% and advice to ‘tell someone’ to 32% of the younger children. The children felt quite positive about their older siblings' advice (89%), which did differ depending on the bullied child's gender. Teen siblings gave advice to ‘avoid bullies’ to 77% of female and to 27% of male younger children. PMID:25931644

  18. Breast cancer screening among women younger than age 50: a current assessment of the issues.

    In the hope of resolving underlying policy questions related to the value of breast cancer screening with mammography for women younger than 50 years of age, the National Institutes of Health and the National Cancer Institute in 1997 jointly sponsored a consensus conference on the subject. While the panel concluded that the data were insufficient to endorse mammography for this age group apart from individual choice, the conclusion was not the "consensus" sought by many of those with strong opinions on both sides of this issue, and the debate raged on. Prior to the 1997 conference, and since, meta-analyses of trial data and assessments of service screening programs have indicated that breast cancer screening with mammography for women between 40 and 49 meets recommended levels of performance compared with performance in women 50 years and older, especially if programs achieve high quality and screen at 12-to-18 month intervals. Because the detectable preclinical phase is shorter in younger women who develop breast cancer compared with that in women 50 years of age or older, a key component of any screening program for those younger than 50 is an appropriate screening interval. Many of the screening programs that had historically been developed for women in their forties--and whose disappointing results contributed to the confusion and controversy about the efficacy of mammography in younger women--had a 24-month screening interval, which was not found to be of significant benefit for early detection of breast cancer in this age group. While a new emphasis of this controversy has focused on the balance of benefits and harms in women ages 40 to 49, women of all ages need to be fully informed about the benefits and limitations of breast cancer screening--more specifically, what to expect at the time of screening, and what to expect from screening. There are differences in the performance and effectiveness of mammography in different age groups of women aged 40 and

    A nursing career can last for more than 40 years, during which continuing professional development is essential. Nurses participate in a variety of learning activities that correspond with their developmental motives. Lifespan psychology shows that work-related motives change with age, leading to the expectation that motives for continuing professional development also change. Nevertheless, little is known about nurses' continuing professional development strategies in different age groups. To explore continuing professional development strategies among younger, middle-aged, and older nurses. A qualitative study using semi-structured interviews, from a biographical perspective. Data were analysed using a vertical process aimed at creating individual learning biographies, and a horizontal process directed at discovering differences and similarities between age groups. Twenty-one nurses in three age groups from general and academic hospitals in the Netherlands. In all age groups, daily work was an important trigger for professional development on the ward. Performing extra or new tasks appeared to be an additional trigger for undertaking learning activities external to the ward. Learning experiences in nurses' private lives also contributed to their continuing professional development. Besides these similarities, the data revealed differences in career stages and private lives, which appeared to be related to differences in continuing professional development strategy; 'gaining experience and building a career' held particularly true among younger nurses, 'work-life balance' and 'keeping work interesting and varied' to middle-aged nurses, and 'consistency at work' to older nurses. Professional development strategies can aim at performing daily patient care, extra tasks and other roles. Age differences in these strategies appear to relate to tenure, perspectives on the future, and situations at home. These insights could help hospitals to orientate continuing

    Kawasaki disease (KD) patients younger than 1 year of age are at especially high risk of developing coronary artery abnormalities (CAA). To define the clinical characteristics of this group, as well as the risk factors predisposing them to CAA, we reviewed the medical records of 136 KD patients younger than 1 year of age who were treated at the Korea University Medical Center from January 2001 to July 2006. Of these patients, 16 developed CAA (11.8%). The CAA(+) group had a longer duration of total fever than the CAA(-) group (9.1+/-3.7 days vs. 6.3+/-2.0 days, p=0.011), but did not differ in the duration of pre- and post-intravenous gamma-globulin (IVGG) fever. The CAA(+) group had fewer diagnostic symptoms than the CAA(-) group (2.7+/-1.1 vs. 4.3+/-1.2, p<0.001). Of the hematological findings, the CAA(+) group only differed from the CAA(-) group in having significantly higher total white blood cell (19.2+/-6.0 vs. 14.7+/-4.7 K/mm(3), p=0.007) and platelet (462.9+/-101.0 vs. 383.6+/-121.1 K/mm(3), p=0.014) levels. Multivariable logistic regression analysis showed that the only factors which were significantly associated with the development of CAA were the total number of symptoms (OR=0.493, 95% CI=0.293-0.829, p=0.007) and the duration of total fever (OR=1.405, 95% CI=1.092-1.808, p=0.008). Conclusively, incomplete clinical manifestations and a longer duration of total fever are significantly associated with the development of CAA in KD patients younger than 1 year of age. Therefore, these patients should be monitored for incomplete KD, especially if unexplained fever continues, and treatment to shorten the duration of total fever should be initiated.

    There is little information on how the duration of overweight or obesity during life affects the risk for CKD. To investigate whether prolonged exposure to overweight during adult life increases the risk of later CKD in a cumulative manner, we analyzed data from the Medical Research Council National Survey of Health and Development, a socially stratified sample of 5362 singleton children born in 1 week in March 1946 in England, Scotland, and Wales. Multiple imputation expanded the analysis sample from the initial 1794 participants with complete data to 4584. This study collected self-reported body mass index (BMI) at ages 20 and 26 years and measured BMI at ages 36, 43, 53, and 60–64 years. The outcome of interest was CKD at age 60–64 years, suggested by estimated GFR (eGFR) overweight at younger ages was associated with higher odds of developing CKD by age 60–64 years. Compared with those who first became overweight at age 60–64 years or never became overweight, those first overweight at age 26 or 36 years had approximately double the odds of developing CKD. The strength of this association decreased with increasing age when first overweight (P for trend overweight in early adulthood may have a considerable effect on the prevalence of CKD in the population.

    Breast cancer in younger patients often presents with adverse histopathological features, including increased frequency of estrogen receptor negative and lymph node positive disease status. Chromosomal instability (CIN) is increasingly recognised as an important prognostic variable in solid tumours......, assessed by the two independently derived CIN expression signatures, is significantly associated with increased tumour size, ER negative or HER2 positive disease, higher tumour grade and younger age at diagnosis in ER negative breast cancer. These data support the hypothesis that chromosomal instability...

    Most single ventricle patients undergo Fontan procedure earlier in current era. However, optimal timing of Fontan completion after an intermediate staging surgery is controversial. We present children who had Fontan surgeries younger than 3 years of age comparing the data with older patients. Between 2000 and 2013, 45 patients with functional single ventricle underwent extracardiac total cavopulmonary connection (TCPC) using GORE-TEX(®) conduit at a single institution. Children were divided into group A (age GORE-TEX(®) conduit size were similar in both groups. The time of chest drain stay was significantly lower in group A (median 12 days, IQR 7-22) than in group B (22 days, IQR 16-32.5) (p = 0.014). Extracardiac TCPC can be performed earlier with good intermediate results. Earlier Fontan procedure might be advantageous for reducing chest drains stay.

    Background: Inflammatory bowel disease (IBD) – Ulcerative colitis (UC) and Crohns Disease (CD) are caused by complex gene-environment interactions and the risk is increased in family members. We investigated whether the risk of IBD in relatives to IBD patients changes by age of the relatives....... Results The age stratified rates of IBD in 1st degree relatives to an IBD affected case, after controlling for the overall effect of age, appear from Table 1. The rate ratio of CD in individuals with two or more 1st degree relatives with IBD is 1-2 fold increased in relatives aged 60+ years, whereas...... it is 67-fold increased risk in relatives aged 0-10 years and 34-fold increased in relatives aged 10-19 years. The same pattern is seen in 1st degree relatives who have one relative with IBD, where the risk of CD is markedly higher in younger relatives, this risk pattern for CD is seen both if the IBD...

    There have been few reports concerning radioactive iodine therapy (RI therapy) for Graves' disease in children, even in the United States of America (USA), and there have been no reports of such treatment in Japan. We evaluated the short-term results of RI therapy for Graves' disease aged 18 or younger. A total of 36 patients (10 male and 26 female) with Graves' disease, aged 18 and younger (range, 13 to 18 years; mean age, 15.8±1.5 years), received RI therapy on an outpatient basis at our clinic between July 1999 and July 2005. The mean interval from initiation of an antithyroid drug (ATD) to RI therapy was 25.3±21.5 months (range, 1 to 78 months). Twenty patients received therapy once, 14 twice, and 2 three times. The mean initial dose of radioactive iodine was 7.8±2.9 mCi (range, 3.6 to 13.0 mCi) and the mean total dose was 12.3±7.7 mCi (range, 3.6 to 29.8 mCi). The mean estimated weight of the thyroid gland was 42.6±23.4 g (range, 15.5 to 99.4 g) before RI therapy and 7.1±3.0 g (range, 2.0 to 13.6 g) after RI therapy. The mean follow-up period after RI therapy was 41.1±18.0 months (range, 6 to 71 months). Currently, 15 patients (42%) have hypothyroidism, 8 (22%) have subclinical hypothyroidism, 5 (14%) have euthyroidism, and 8 (22%) have subclinical hyperthyroidism. Patients taking thyroid hormone were considered hypothyroid. Patients with subclinical hypothyroidism are currently being monitored without treatment. No patients with subclinical hyperthyroidism are taking an ATD or KI (potassium iodide). A total of 36 patients with Graves' disease, aged 18 and younger, received RI therapy, and the short-term outcome in these patients were favorable. However, prolonged follow-up observation is required to confirm long-term safety. (author)

    Fever in infants younger than 3 months is generally a cause for concern because of the risk for a serious bacterial infection. The aim of this study was to describe clinical and biologic features of Chikungunya infection in infants Chikungunya polymerase chain reaction. One hundred and twenty infants were hospitalized with fever. The mean age was 46 days (standard deviation ± 22 days). The mean hospitalization duration was 7.4 days (standard deviation ± 6.1 days). Chikungunya infection was diagnosed in 26 children. The most important clinical findings were high [80.8% (77.5-84)] and prolonged fever [76.9% (73.4-80.4)], irritability [96.2% (94.5-97.7)] and skin rash [69.2% (65.4-73)]. Half of the infants presented edema of the extremities (hands and feet principally). However, in 15% of infants, Chikungunya infection was associated with a serious bacterial infection. Infants who presented with irritability, high fever and elevated PCT were at high risk for Chikungunya: OR 39 (9.2-243; P < .001), with a specificity of 96.7% and a negative predictive value of 89.4%. The area of the receiver operating characteristic curve was 0.96. Our results confirm that Chikunguyna infection is a cause of high fever in infants younger than 3 months. Our data should be confirmed by larger studies.

In this study, we prospectively assessed the association between different baseline characteristics (age, tumor characteristics, mode of treatment, etc and outcomes among newly diagnosed nonmetastatic Lebanese breast cancer patients.Methods: We recruited a sample of 123 women newly diagnosed with nonmetastatic breast cancer presenting to American University of Beirut Medical Center. Immunohistochemical, molecular (vitamin D receptor, methylene tetrahydrofolate reductase polymorphisms, and genetic assays were performed. Patient characteristics were compared by age group (<40 and ≥40 years. A Cox regression analysis was performed to evaluate the variables affecting the disease-free survival (DFS. Outcome data were obtained, and DFS was estimated.Results: Among the 123 patients, 47 were 40 years of age or younger, and 76 were older than 40 years. Median follow-up duration was 58 months. Nine out of 47 patients <40 years (19.1% experienced disease relapse in contrast to four out of 76 patients >40 years (5.2%. A wide immunohistochemical panel included Ki-67, cyclin B1, p53, platelet-derived growth factor receptor, and vascular endothelial growth factor receptor, and did not reveal any significant difference in these markers between the two age groups. Older patients had a larger percentage of Luminal A than younger patients. On multivariate analysis

    Only few studies have examined the impact of racial differences on the age of onset, course and outcomes of diverticulitis. To provide data about the epidemiology of diverticulitis in northern Israel, and to determine whether ethnicity is a predictor of age of onset, complications, and need for surgery. Was conducted a retrospective review of the charts of all patients diagnosed with a first episode of diverticulitis in our hospital between 2005 and 2012. Were found 638 patients with a first episode of acute diverticulitis in the eight year interval. Israeli Arabs developed a first episode of diverticulitis at a younger age compared to Jews (51.2 vs 63.8 years, pdiverticulitis at a younger age than Arabs living in urban centers (49.4 vs 54.5 years, P=0.03). Jewish and Arabic men developed diverticulitis at younger age compared to their female counterparts (59.9 vs 66.09, pdiverticulitis. Israeli Arabs tend to develop diverticulitis at a younger age and are more likely to require surgical treatment for diverticulitis compared to Jews. Arabs living in rural areas develop diverticulitis at a younger age than Arabs living in urban centers. These findings highlight a need to address the root cause for ethnic differences in onset, course and outcome of acute diverticulitis.

    Full Text Available Extreme conditions of the North, computerization, Internet and a gadget dependence, high physical and intellectual loads of children activities living in the north negatively affect younger generation health state. It is difficult to overestimate a role of motor activity in expansion of functionality of the developing organism as the lack of locomotion can lead to pathological shifts in an organism. Based on the study of the concept of a ‘motor activity’ and features North of the city the article suggests a model of motor activity optimization of younger school age children living in the conditions of the northern city. It consisted of 6 units related to goal-setting, diagnostic-analytical, concept, process-activity, reflexive-evaluative and effective. The research was conducted on the basis of Surgut city schools and the Surgut region of Khanty-Mansi Autonomous Region-Yugra. During the research we revealed the most priority organization forms of motor activity of younger school age children living in conditions of the northern city. The model of motor activity optimization of younger school age children allows to create necessary optimum volume and to control of motor activity of children of younger school age. Purpose. The purpose of our research was to create model of motor activity optimization of younger school age children living in the conditions of the northern city. Methodology. Analysis and synthesis of the materials as well as the method of simulation are used as the main instruments. Results. A model of motor activity optimization of younger school age children has been elaborated in the course of study and its characteristics have been specified. Practical implications. The results can be of use for teachers at professional educational institutions.

    Little is known about the trends in health care spending for the 156 million Americans who are younger than age sixty-five and enrolled in employer-sponsored health insurance. Using a new source of health insurance claims data, we estimated per capita spending, utilization, and prices for this population between 2007 and 2011. During this period per capita spending on employer-sponsored insurance grew at historically slow rates, but still faster than per capita national health expenditures. Total per capita spending for employer-sponsored insurance grew at an average annual rate of 4.9 percent, with prescription spending growing at 3.3 percent and medical spending growing at 5.3 percent. Out-of-pocket medical spending increased at an average annual rate of 8.0 percent, whereas out-of-pocket prescription drug spending growth was flat. Growth in the use of medical services and prescription drugs slowed. Medical price growth accelerated, and prescription price growth decelerated. As a result, changes in utilization contributed less than changes in price did to overall spending growth for those with employer-sponsored insurance.

    2015-01-01

    This scoping review was conducted to understand the extent, range, and nature of current research on adolescents and young adults (AYA) with cancer and distress, depression, and anxiety (DDA). This information is necessary to find and aggregate valuable data on the AYA population embedded in generalized studies of DDA. Keyword searches of six relevant electronic databases identified 2156 articles, with 316 selected for abstract review and 40 for full text review. Full-text reviews and data extraction resulted in 34 studies being included, which ranged widely in design, sample size, age-range categorization, analysis methods, DDA measurement tool, overall study rigor, and quality of evidence. Studies very seldom reported using theory to guide their age categorization, with only four studies giving any rationale for their age-group definitions. All 34 studies found a significant association between at least one DDA construct and the younger age group relative to the older age groups at some point along the cancer trajectory. However, age as an independent risk factor for DDA is still unclear, as the relationship could be confounded by other age-related factors. Despite the wide range of definitions and effect sizes in the studies included in this review, one thing is clear: adolescents and young adults, however defined, are a distinct group within the cancer population with an elevated risk of DDA. Widespread adoption of a standard AYA age-range definition will be essential to any future meta-analytical psycho-oncology research in this population. PMID:26697266

    Full Text Available Background. In general, younger age is associated with better survival in patients with colon cancer. In this study, we aim to analyze the impact of age on cancer-specific survival (CSS in patients with signet-ring cell carcinoma (SRCC of the colon, a particularly aggressive type of colon cancer. Methods. Information on patients with SRCC of the colon with no distant metastasis was extracted from the US Surveillance, Epidemiology, and End Results (SEER database. An X-tile plot was used to determine the optimal cutoff age at diagnosis. Results. A total of 776 patients were included in data analysis. The X-tile program revealed an optimal cutoff at 35 years of age. A higher percentage of stage III disease and a higher percentage of N2 disease were observed in patients ≤ 35 years of age. The multivariate Cox proportional model demonstrated that patients ≤ 35 years of age were more likely to have a poorer survival outcome compared with patients aged >35 years (HR 1.411, 95% CI 1.032–1.929, and P=0.031. Conclusion. In contrast to the association of younger age with better survival in colon cancer patients, younger age (≤35 years is associated with poorer survival outcome in patients with SRCC of the colon without distant metastasis.

    There is a shortage of data about acute heart failure (AHF) in the young, including its underlying causes, clinical presentation and outcomes. We aim to describe clinical characteristics, causes and outcomes of AHF in Yemeni patients aged 50years or younger. we evaluated Yemeni patients with AHF enrolled in Gulf CARE registry. Patients were divided into two groups: young patients (≤50years) and older patients (>50years). A total of 1536 patients with AHF were enrolled, of whom 635 (41.3%) were 50years old or younger. The mean age for this group was 38.8 (±9.5) years; and 399 (62.8%) were males. Younger patients had a higher prevalence of non-ischemic cardiomyopathy (41% vs 11.1%, pvalvular disease (27.9% vs 3.2%, pdisease (61.6% vs 25.5%, pdisease (18.3% vs 6.3%, p<0.001) were more frequent in the elderly group. Cardiogenic shock was more frequent among younger patients (13.7% vs 7.0, p<0.001). In-hospital mortality was higher in patient aged ≤50years (12% vs 7.6%, p=0.002) while no difference in all-cause mortality was present at 3months (17.8 vs 14.5, p=0.089) and after 1year (21.9% vs 20.6%, p=0.56). This analysis of Gulf CARE registry represents the largest report of patients admitted with AHF in Yemen. There were differences among cause of HF and precipitating factors of AHF among younger and elderly patients. Younger patients had higher in-hospital mortality and more severe clinical condition at admission. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

    Full Text Available Worldwide, breast cancer is the most frequently diagnosed life-threatening cancer and the leading cause of cancer death among women. Approximately 7% of all breast cancers are diagnosed in women <40 years of age. Young age at diagnosis influences prognosis negatively as they present with more advanced disease at diagnosis and a poorer 5-year survival than older patients. The present study includes breast cancer patients in the age group of 18 to 40 years to enrich our knowledge about clinical presentation and pathological characteristics of breast cancer. To find out the clinical presentation and pathological characteristics of breast cancer among the young age group.  This cross-sectional study was done over 100 cases of histopathologically proven breast cancer from structured Questionnaire was used as data collection tool. Mean age was 33.89 years. Among the respondents 88% are married. Among the total studied population 61 respondents had the history of oral contraceptive pill use. Family history of cancer presents in 13.0% respondents and absent in 87.0% respondents. Among the respondents 95% patients presented with lump in the breast. 97.0% had invasive carcinoma 90% were invasive ductal carcinoma in which 46.0% were moderately differentiated. 51.0% patients were in the stage IIa and stage IIb.

    To compare rate of acute stress disorder (ASD) and intensity of acute stress symptoms (ASS) in younger, middle-aged and older Israeli citizens exposed to missile attacks during the second Lebanon war. A telephone survey of a random sample of residents in the northern area of Israel was conducted in July 2006, during the third week of Lebanon war. Respondents were divided into groups aged 18-40, 41-69 and 70+. ASD and ASS were measured by the Acute Stress Interview questionnaire and by war-related exposure variables and demographic data. Exposure variables were similar in the three age groups. Older respondents reported lower intensity of ASS and obtained lower means for each of the symptoms criteria than the young adults, while the middle-aged adults were in between the younger and the older group. ASD criteria were met by 13.2% of the younger, 4.7% of middle-aged and 4.3% of older respondents (p > 0.05), and subsyndromal ASD was found in 20.5%, 14.1% and 4.4% (p war situation with lower level of acute stress symptoms. Long-term effects of war on different age groups should be further studied.

    Full Text Available Abstract Background Childhood obesity has become a major public health problem in China. The objective of this study was to examine the effect of age and sex on the relationship between fat-free mass (FFM and fat mass (FM, fat-free mass index (FFMI and fat mass index (FMI in Chinese children using body composition chart analysis, and to compare the changing pattern with Caucasian and Japanese counterparts. Methods A total of 1458 children (790 boys and 668 girls between 5 and 18 years of age were studied to determine a body composition by bioelectrical impedance analysis. The relationship of FFM and FM, FFMI and FMI were delineated by body composition charts. Results Different changing patterns in body composition were observed during 5-11y (younger age group, and 12-18y (older age group, with non-significant sex difference with FM and FMI for the younger age group and significant sex and age differences for the older age group. For the younger age group, simultaneous increase of FFM and FM was found in both genders. However, for the older age group, the increase in weight and BMI with age is largely due to the increment of FFM and FFMI in boys, and of FM and FMI in girls. In addition, different changing patterns in body composition exist between Chinese children and their Caucasian and Japanese counterparts, largely due to the higher fat mass component in Chinese subjects. Conclusions Our results indicate that age- and gender-related changing patterns of body composition in Chinese children may differ at different growth stage, and differ with those in Caucasian and Japanese children at the same age period. Such changing patterns should be considered when designing the intervention proposal for childhood obesity in China.

    The home remains a very common location for deadly injuries among children younger than 5 years. The aim of this study is to describe the demographic and injury characteristics of domestic injuries in children younger than 5 years. The National Trauma Data Bank's National Sample Program data set was queried for children younger than 5 years with the injury site classified as home. Bivariate analysis was performed to determine unadjusted differences by ethnicity. Appropriate weight was applied to the sample to determine accurate national estimates. A total of 7,364 children, representing 32,033 children, were analyzed. Overall mortality was 1.6 per cent. Among whites, blacks, Hispanics, Asians, and Native Americans, intentional injuries accounted for 6.5, 12.8, 10.2, 5.2, and 19.0 per cent of all injuries by intent, respectively (P injuries were significantly higher in blacks and Native Americans with black patients sustaining a disproportionately higher proportion of burn injury. Therefore, greater attention is needed to provide more effective home safety interventions to children among high-risk ethnic groups.

Two groups consisting of eight healthy male Wistar Albino rats [young (30 ± 7 days) and aged (360 ± 30 days)], and a cutaneous incision wound healing model were used. Scar tissue samples from wounds on the 7th, 14th and 21st days of healing were evaluated for hydroxyproline and vascular endothelial growth factor content. Macrophage, lymphocyte, fibroblast and polymorphonuclear cell infiltration; collagen formation and vascularization were assessed by light and electron microscopy. The free oxygen radical content of the wounds was measured by a chemiluminescence method. Blood sample analysis showed that the hydroxyproline and total testosterone levels were significantly higher, and the oxygen radical content was significantly lower in young rats. Histopathological, immunohistochemical and ultrastructural evaluations revealed higher amounts of fibroblasts and collagen fibers, and more vascularization in young rats. These results are indicative of the delayed wound healing in aged rats. A combination of multiple factors including hormonal regulation, free oxygen radicals and impaired angiogenesis appears to be the cause of delayed cutaneous healing. © 2011 The Authors.

    OBJECTIVE Neurocognitive impairments commonly occur and adversely impact everyday functioning in older adults infected with HIV, but little is known about successful cognitive aging (SCA) and its health-related quality of life (HRQoL) correlates. METHOD Seventy younger (≤ 40 years) and 107 older (≥ 50 years) HIV+ adults, as well as age-matched seronegative comparison groups of younger (N=48) and older (N=77) subjects completed a comprehensive battery of neuropsychological, psychiatric, medical, and HRQoL assessments. SCA was operationalized as the absence of both performance-based neurocognitive deficits and self-reported symptoms (SCA-ANDS) as determined by published normative standards. RESULTS A stair-step decline in SCA-ANDS was observed in accordance with increasing age and HIV serostatus, with the lowest rates of SCA-ANDS found in the older HIV+ group (19%). In both younger and older HIV+ adults, SCA-ANDS was strongly related to better mental HRQoL. CONCLUSION HIV infection has additive adverse effects on SCA, which may play a unique role in mental well-being among HIV-infected persons across the lifespan. PMID:24633788

    To evaluate outcomes after treatment of rape-induced urogenital and lower gastrointestinal lesions among young girls. In a retrospective study, data were assessed from girls aged 5 years or younger who were treated for sexual-assault-related injuries at the General Referral Hospital, Panzi, Bukavu, Democratic Republic of Congo, between 2004 and 2014. Data were obtained from review of charts, records of the mother's impressions and physical examinations, and photographic evidence. Elective surgery had been reserved for patients experiencing fecal and/or urinary incontinence. Overall, 205 girls aged 5 years or younger presented with rape injuries: 162 (79.1%) had only mucocutaneous lesions, 22 (10.7%) had musculocutaneous lesions, and 21 (10.2%) had musculocutaneous lesions complicated by fecal and/or urinary incontinence. Among the 21 girls who underwent perineal surgery, two with fecal and urinary incontinence and perforation of the peritoneum of Douglas pouch were additionally treated by laparoscopy. Among 16 patients with fecal incontinence, the continence score had improved significantly at 10.4 months after surgery (Prape survivors aged 5 years or younger, a treatment strategy by which surgery is reserved for incontinent patients provided good cosmetic and functional outcomes.

    Idursulfase beta (Hunterase®) has been used for enzyme replacement therapy (ERT) of patients with mucopolysaccharidosis II (MPS II, Hunter syndrome) aged 6 years or older since 2012 in Korea. The objective of this study was to evaluate the safety and efficacy of ERT with idursulfase beta in Hunter syndrome children younger than 6 years. This study was a 52-week, single center, single arm, open-label clinical trial (NCT01645189). Idursulfase beta (0.5mg/kg/week) was administered intravenously for 52 weeks. The primary endpoint was safety assessed by adverse events (AEs). Secondary endpoints included vital signs, physical examination, ECG, laboratory tests, anti-idursulfase antibodies, and efficacy represented by changes in urinary glycosaminoglycan (GAG) at week 53 from baseline. In addition, growth indices and developmental milestones (Denver II test) were evaluated as exploratory variables. All six patients experienced at least one AE. A total of 109 AEs were reported. One patient experienced a serious AE (hospitalization due to gastroenteritis) that was considered not to be treatment related. One patient (16.7%) experienced infusion-related adverse drug reactions (ADRs), developing urticaria six times and a cough five times. There were no serious ADRs and no clinically significant changes in vital signs, physical exam, laboratory parameters, or ECG. Of the six patients, four (66.7%) showed anti-idursulfase antibodies and neutralizing antibodies on at least one occasion during the study. At week 53, urinary GAG was significantly reduced by -35.1±30.6mgGAG/g creatine from baseline (P=0.038). This study indicates that the safety and efficacy of idursulfase beta are similar to those reported in Hunter syndrome patients aged 6 years or older. Copyright © 2014 Elsevier Inc.

    Full Text Available There are few pathologic descriptions of fatal coronary artery disease in the young. The morphologic characteristics of sudden coronary deaths in 47 hearts from patients younger than 40 years were studied. Numbers of plaques with necrotic cores were quantitated in each heart. Compared to 194 sudden coronary deaths >40 years, heart weight was lower, acute plaque erosions more frequent, and extent of disease less in the ≤40 years group. Plaque burden was less in hearts with erosions, and healed infarcts more common in hearts with stable plaque. The numbers of fibroatheromas increased with age until the 6th decade (<.0001 as well as the proportion of total plaques that were atheromatous. Plaques in younger patients have fewer lipid-rich cores. Most thrombi show areas of organization, with layering frequent in erosions, suggesting a possible method of plaque enlargement in the absence of necrotic core formation.

    We aimed to describe and compare survival in teenagers and young adults (TYAs) with cancer to that of younger children and older adults, to identify sub-populations at greater or lesser risk of death. We compared survival in cancer patients diagnosed in the United Kingdom aged 13-24 years (TYAs) to those aged 0-12 (children) and 25-49 years (adults) using the National Cancer Data Repository. All cases had a first cancer diagnosis between 1st January 2001 and 31st December 2005 with censor date 31st December 2010 or death if earlier. We found six distinct statistically significant survival patterns. In pattern 1, the younger the age-group the better the 1- and 5-year survival (acute lymphoid leukaemia, carcinoma of ovary and melanoma). In pattern 2, TYAs had a worse 5-year survival than both children and young adults (bone and soft tissues sarcomas). In pattern 3, TYAs had a worse 1-year survival but no difference at 5-years (carcinoma of cervix and female breast). In pattern 4, TYAs had better 1-year survival than adults, but no difference at 5 years (carcinoma of liver and intrahepatic bile ducts, germ cell tumours of extra-gonadal sites). In pattern 5, the younger the age-group the better the 5-year survival, but the difference developed after 1-year (acute myeloid leukaemia, carcinoma of colon and rectum). In pattern 6, there was no difference in 1- and 5-year survival between TYAs and adults (testicular germ cell tumours, ovarian germ cell tumours and carcinoma of thyroid). TYAs with specific cancer diagnoses can be grouped according to 1- and 5-year survival patterns compared to children and young adults. To further improve survival for TYAs, age-specific biology, pharmacology, proteomics, genomics, clinician and patient behaviour studies embedded within clinical trials are required.

  15. Feeling younger and identifying with older adults: Testing two routes to maintaining well-being in the face of age discrimination.

    Directory of Open Access Journals (Sweden)

    Bibiana M Armenta

    Full Text Available Integrating the social identity and aging literatures, this work tested the hypothesis that there are two independent, but simultaneous, responses by which adults transitioning into old age can buffer themselves against age discrimination: an individual response, which entails adopting a younger subjective age when facing discrimination, and a collective response, which involves increasing identification with the group of older adults. In three experimental studies with a total number of 488 older adults (50 to 75 years of age, we manipulated age discrimination in a job application scenario and measured the effects of both responses on perceived health and self-esteem. Statistical analyses include individual study results as well as a meta-analysis on the combined results of the three studies. Findings show consistent evidence only for the individual response, which was in turn associated with well-being. Furthermore, challenging previous research, the two responses (adopting a younger subjective age and increasing group identification were not only theoretically, but also empirically distinct. This research complements prior research by signaling the value of considering both responses to discrimination as complementary rather than mutually exclusive.

Not only do youths tend to accumulate more pack-years but they have more difficulty quitting. The recent shift in smoking trends from tobacco cigarettes to e-cigarettes may not be helpful since both contain the addictive component, nicotine. Although e-cigarettes are marketed as a smoking cessation tool, there is no strong evidence to support these claims, the authors report."I think most people realize nicotine is addictive, but I don't know if there's an understanding of just how addictive it is – particularly for youths," said Lorena M.

    High levels of nanodiamonds (nds) have been used to support the transformative hypothesis that an extraterrestrial (ET) event (comet explosion) triggered Younger Dryas changes in temperature, flora and fauna assemblages, and human adaptations [Firestone RB, et al. (2007) Proc Natl Acad Sci USA 104(41):16016-16021]. We evaluate this hypothesis by establishing the distribution of nds within the Bull Creek drainage of the Beaver River basin in the Oklahoma panhandle. The earlier report of an abundance spike of nds in the Bull Creek I Younger Dryas boundary soil is confirmed, although no pure cubic diamonds were identified. The lack of hexagonal nds suggests Bull Creek I is not near any impact site. Potential hexagonal nds at Bull Creek were found to be more consistent with graphene/graphane. An additional nd spike is found in deposits of late Holocene through the modern age, indicating nds are not unique to the Younger Dryas boundary. Nd distributions do not correlate with depositional environment, pedogenesis, climate perturbations, periods of surface stability, or cultural activity.

    Full Text Available Abstract Background An ad hoc peer-review committee was jointly appointed by Drug Authorities and Industry in Germany, Austria and Switzerland in 1999/2000 to review the evidence for a causal relation between phenacetin-free analgesics and nephropathy. The committee found the evidence as inconclusive and requested a new case-control study of adequate design. Methods We performed a population-based case-control study with incident cases of end-stage renal disease (ESRD under the age of 50 years and four age and sex-matched neighborhood controls in 170 dialysis centers (153 in Germany, and 17 in Austria from January 1, 2001 to December 31, 2004. Data on lifetime medical history, risk factors, treatment, job exposure and intake of analgesics were obtained in a standardized face-to-face interview using memory aids to enhance accuracy. Study design, study performance, analysis plan, and study report were approved by an independent international advisory committee and by the Drug Authorities involved. Unconditional logistic regression analyses were performed. Results The analysis included 907 cases and 3,622 controls who had never used phenacetin-containing analgesics in their lifetime. The use of high cumulative lifetime dose (3rd tertile of analgesics in the period up to five years before dialysis was not associated with later ESRD. Adjusted odds ratios with 95% confidence intervals were 0.8 (0.7 – 1.0 and 1.0 (0.8 – 1.3 for ever- compared with no or low use and high use compared with low use, respectively. The same results were found for all analgesics and for mono-, and combination preparations with and without caffeine. No increased risk was shown in analyses stratifying for dose and duration. Dose-response analyses showed that analgesic use was not associated with an increased risk for ESRD up to 3.5 kg cumulative lifetime dose (98 % of the cases with ESRD. While the large subgroup of users with a lifetime dose up to 0.5 kg (278 cases and

    Previous studies on stroke recurrence in younger adults often contain small sample size which makes it difficult to study trends in stroke recurrence over a long period of time. The aim of the present study was to investigate temporal trends in the risk of recurrence in younger patients with a first ischemic stroke. All men and women aged 18-54 years who had survived at least 28 days after a first ischemic stroke from 1987 to 2006 were identified in the Swedish Inpatient Register. The patients were stratified into four 5-year periods according to their admission period and were followed up for a total of four years after the index event with regard to recurrent ischemic stroke. A Cox regression model was used to analyze the risk of recurrent ischemic stroke. Of the 17,149 ischemic stroke patients who were identified, 2432 (14.2%) had a recurrent ischemic stroke event within four years. From the first to the last periods (1987-1991 versus 2002-2006), the four-year risk of recurrent ischemic stroke decreased by 55% (hazard ratio 0.45, 95% confidence interval 0.39-0.53) in men and 59% (hazard ratio 0.41, 95% confidence interval, 0.33-0.50) in women. The cumulative four-year risk was 11.8% (95% CI 10.55-13.25) in men and 9.8% (95% CI 8.40-11.46) in women during the last five-year period (2002-2006). The risk of recurrence among younger ischemic stroke patients has decreased over the past 20 years. Despite these improvements, younger patients are still at a high risk for recurrent ischemic stroke. © 2016 World Stroke Organization.

    Full Text Available Abstract Background Cardiovascular risk factors start early, track through the young age and manifest in middle age in most societies. We conducted epidemiological studies to determine prevalence and age-specific trends in cardiovascular risk factors among adolescent and young urban Asian Indians. Methods Population based epidemiological studies to identify cardiovascular risk factors were performed in North India in 1999–2002. We evaluated major risk factors-smoking or tobacco use, obesity, truncal obesity, hypertension, dysglycemia and dyslipidemia using pre-specified definitions in 2051 subjects (male 1009, female 1042 aged 15–39 years of age. Age-stratified analyses were performed and significance of trends determined using regression analyses for numerical variables and Χ2 test for trend for categorical variables. Logistic regression was used to identify univariate and multivariate odds ratios (OR for correlation of age and risk factors. Results In males and females respectively, smoking or tobacco use was observed in 200 (11.8% and 18 (1.4%, overweight or obesity (body mass index, BMI ≥ 25 kg/m2 in 12.4% and 14.3%, high waist-hip ratio, WHR (males > 0.9, females > 0.8 in 15% and 32.3%, hypertension in 5.6% and 3.1%, high LDL cholesterol (≥ 130 mg/dl in 9.4% and 8.9%, low HDL cholesterol ( Conclusion Low prevalence of multiple cardiovascular risk factors (smoking, hypertension, dyslipidemias, diabetes and metabolic syndrome in adolescents and rapid escalation of these risk factors by age of 30–39 years is noted in urban Asian Indians. Interventions should focus on these individuals.

    Full Text Available Background and Purpose: The modified functional reach test (MFRT is the objective measure for dynamic sitting balance. It quantifies sitting balance in two directions: Forward and lateral reach. So, the purpose of the study was to 1 provide clinical reference value and 2 examine the factors that may influence the anthropometrics measures. Materials and Methods: A total of 200 apparently healthy subjects participated in this descriptive study. All subjects were divided in two groups: Younger (20-39 yr and middle-aged (40-59 yr. After anthropometric measurement, all subjects performed test by reaching forward and lateral with a closed fist while sitting. MFRT was taken with 3 trials with 15 sec break in between. Results: The mean score of the forward and lateral reach of right and left in group 1 was higher compared to group 2. The normative value of forward reach in group 1 was 34.05 ± 9.03 cm; for lateral reach right and left, it was 18.2 ± 5.26 cm and 17.32 ± 5.21 cm, respectively. For group 2, normative values for forward reach, lateral right and left were 25.18 ± 5.71 cm, 14.02 ± 3.98 cm and 13.53 ± 4.25 cm, respectively. There was no significant correlation of forward and lateral reach measures with the anthropometric characteristics in both the groups, except trunk length and BMI in group 1, which was significantly correlated ( P < 0.001. Conclusion: This study provides clinical reference value for younger and middle age group subjects while anthropometrics do not affect performance except trunk length and BMI in younger age group.

    Objective To estimate the incidence of first hip or clinical vertebral fracture or major osteoporotic (hip, clinical vertebral, proximal humerus or wrist) fracture in postmenopausal women receiving their first bone mineral density (BMD) test before age 65. Methods We studied 4068 postmenopausal women aged 50 to 64 without hip or clinical vertebral fracture or antifracture treatment at baseline, participating in the Women's Health Initiative BMD cohort study. BMD tests were performed between October 1993 and April 2005, with fracture follow-up through 2012. The outcomes were the times for 1% of women to sustain a hip or clinical vertebral fracture, and for 3% to sustain a major osteoporotic fracture before initiating treatment, adjusting for clinical risk factors and accounting for competing risks. Women without and with osteoporosis on their first BMD test were analyzed separately. Results During a maximum 11.2 years of concurrent BMD and fracture follow-up, the adjusted estimated time for 1% of women to have a hip or clinical vertebral fracture was 12.8 years (95% CI, 8.0, 20.4) for aged 50 to 54 and 7.6 years (95% CI, 4.8 to 12.1) for aged 60 to 64 for those without baseline osteoporosis, and 3.0 years (95% CI, 1.3, 7.1) for all women aged 50 to 64 with baseline osteoporosis. Results were similar for major osteoporotic fracture. Conclusion Due to very low rates of major osteoporotic fracture, postmenopausal women age 50 and 64 without osteoporosis on a first BMD test are unlikely to benefit from frequent rescreening before age 65.

    Conclusion In summary, the results of the present study showed that during walking with self-selected and fast speeds, the reaction forces of weight acceptance and heel off phases were significantly different between younger and older adults, but there was no significant difference in the reaction force of midstance phase. Moreover, in both age groups, there were significant differences among walking different speeds in the reaction forces of weight acceptance and heel off phases. It seems that lower extremity muscles strengthening in the older adults can increase walking speed and decrease falling risks and functional disabilities of these people.

    This study aims to examine the autopsy-determined principal and proximate causes of death in 25 patients aged 20 years or younger who died during the 10-year period from 1990 to 1999 after receiving an organ transplant at the University of Minnesota/Fairview-University Medical Center. The autopsy records of this institution were examined for organ transplant recipients who were aged 20 years or younger at the time of their death. In each case, after review of the clinical and pathological data, the principle cause of death (PCOD), as well as the proximate cause of death (PXCOD) were noted. A total of 25 recipient patients were identified (five heart, five lung, five kidney and 10 liver transplants). Seven patients died 30 days or less post-operatively and 18 died thereafter. The following categories of PCOD were encountered: operative/technical complications 28%, most (6/7) being associated with liver transplantation. Infection (24%) and chronic rejection (12%) were other important PCOD. Respiratory complications accounted for 47% of the PCOD. The following categories of PXCOD were noted: technical problems 16%, pulmonary pathology 24%, miscellaneous 32%, acute rejection 4% and nil 20%. This study revealed that technical problems in liver transplants were an important PCOD; respiratory complications and chronic rejection were additional major causes of mortality in this young age group of transplant recipients. Pulmonary pathology and technical problems were the commonest specific groups contributing to the PXCOD.

    To examine the association of plasma carotenoids, micronutrients in fruits, and vegetables, with risk of premalignant breast disease (PBD) in younger women. Blood samples were collected at the Siteman Cancer Center between 2008 and 2012 from 3537 women aged 50 or younger with no history of cancer or PBD. The analysis included 147 participants diagnosed with benign breast disease or breast carcinoma in situ during a 27-month follow-up and 293 controls. Cases and controls were matched on age, race/ethnicity, and date of and fasting status at blood draw. Plasma carotenoids were quantified. We used logistic regression to calculate odds ratios (ORs) and 95% confidence intervals (CIs) and linear regression to assess racial differences in plasma carotenoids. The risk reduction between the highest and lowest tertiles varied by carotenoid, with β-cryptoxanthin having the greatest reduction (OR 0.62; 95% CI, 0.62-1.09; P trend  = 0.056) and total carotenoids the least (OR 0.83; 95% CI, 0.48-1.44; P trend  = 0.12). We observed an inverse association between plasma carotenoids and risk of PBD in obese women (BMI ≥ 30 kg/m 2 ; 61 cases and 115 controls) but not lean women (BMI carotenoids and risk of PBD in younger women, consistent with inverse associations reported for invasive breast cancer. Carotenoids may play a role early in breast cancer development.

  9. Early Menarche is Associated With Preference for Masculine Male Faces and Younger Preferred Age to Have a First Child

    Full Text Available One developmental factor that is associated with variation in reproductive strategy is pubertal timing. For instance, women who experience earlier menarche have their first pregnancy earlier and prefer more masculinized male voices. Early menarche may also lead to preferences for masculine faces, but no study has shown such a link. We therefore investigated the relationships between pubertal timing, reproductive plans, sexual attitudes and behaviors, and masculinity preferences in nulliparous women aged 18–30 from the United Kingdom (N = 10,793. We found that women who experienced earlier menarche reported a younger preferred age to have a first child and showed stronger masculinity preferences. This provides evidence that women experiencing early menarche not only have children earlier but notably plan to have children earlier. Additionally, our findings provide evidence that age of menarche influences partner selection, which is instrumental for the implementation of reproductive strategies.

    Rakison, David H; Krogh, Lauren

    2012-01-01

    Previous research has established that infants are unable to perceive causality until 6¼ months of age. The current experiments examined whether infants' ability to engage in causal action could facilitate causal perception prior to this age. In Experiment 1, 4½-month-olds were randomly assigned to engage in causal action experience via Velcro sticky mittens or not engage in causal action because they wore non-sticky mittens. Both groups were then tested in the visual habituation paradigm to assess their causal perception. Infants who engaged in causal action - but not those without this causal action experience - perceived the habituation events as causal. Experiment 2 used a similar design to establish that 4½-month-olds are unable to generalize their own causal action to causality observed in dissimilar objects. These data are the first to demonstrate that infants under 6 months of age can perceive causality, and have implications for the mechanisms underlying the development of causal perception. © 2011 Blackwell Publishing Ltd.

    Full Text Available A locality in the district of Tlalpan, Mexico City, was selected in order to identify the viral agents in children younger than 5 years of age with acute respiratory infection (ARI. A total of 300 children were randomly selected and were included in this study for a period of 13 months. During this period nasopharyngeal exudates were collected for the isolation of viral agents. Monoclonal fluorescent antibodies were used for viral identification after cell culture. Viral infection was detected in 65% of the specimens. The respiratory syncytial virus (RSV was the most common virus agent detected. Children required an average of two consultations during the study period. Two high incidence peaks were observed, one during the summer and the other during winter; the most frequent viruses during these seasons were influenza A and RSV, respectively. The largest number of viruses was isolated in the group of children between 1 and 2 years of age and in the group between 4 and 5 years of age. This study demonstrated the presence of ARI and of different viruses in a period of 13 months, as well as the most frequent viruses in children younger than 5 years of age from a community of Mexico City.

    Full Text Available This paper deals with assessment of motor abilities on the sample of 164 subjects of boys from major cities of Vojvodina, divided in three groups according to their IQ. Assessment was carried out by the test battery of 7 motor tests: Obstacle course backwards, Hand tapping, Seated straddle stretch, Standing broad jump, 20m run, Sit-up, Bent-arm hang, as well as by Raven's progressive matrices in color for assessment of cognitive abilities. Subject of this paper are motor and cognitive abilities of boys at the age of 7-10. The purpose of research is to define differences in motor abilities of children at different intellectual levels. Significance of this research is primarily related to getting concrete data on engagement of cognitive abilities in performing motor tasks of different complexity. Research results of the above sample indicated that coordination seven to eight years old boys had statistical significant relations with cognitive abilities, hence motor tasks i.e. tasks of unusual structure to be carried out fast and correctly, which represented these abilities took effect on differences between groups, whereas repetitive strength, static strength and flexibility did not significantly affect the difference between groups.

  18. ALGORITHM OF TREATMENT OF CONGENITAL CLUBFOOT IN CHILDREN OF YOUNGER AGE GROUP

    Directory of Open Access Journals (Sweden)

    Ирина Юрьевна Клычкова

    2013-03-01

    Full Text Available Congenital clubfoot requires complete correction before the period of verticalization. Conservative methods are priority in treatment. The most effective method is Ponseti method that allows correcting all the deformations even in severe clubfoot. However, if clubfoot is accompanied with abnormal anatomy of foot or significant changes in functional ability of muscles, operative treatment is inevitable. The extent of surgical intervention depends on the severity of detected abnormalities and is determined individually. The use of ultasound, radiographic, and CT investigations, according to indications, contributes to the diagnostics. The indication for surgery is the lack of effect of conservative treatment after 10-12 cast correction in children over the age of 4 months. Diagnostic criteria for deciding in favor of surgery are: availability of fibrous coalition, the deformation of the talar or the sphenoid bone, the anomaly in the point of attachment of the tendon of the tibialis anterior muscle, lack of the repositioning of navicular bone on the talar head. Orthosis supply and rehabilitation treatment depend on the extent of surgical intervention.

    Cervical lymph node metastases are recognized as a prognostic indicator only in patients age 45 years or older with papillary thyroid cancer (PTC); patients younger than age 45 years are perceived to have low-risk disease. The current American Joint Committee on Cancer staging for PTC in patients younger than age 45 years does not include cervical lymph node metastases. Our objective was to test the hypothesis that the presence and number of cervical lymph node metastases have an adverse impact on overall survival (OS) in patients younger than age 45 years with PTC. Adult patients younger than age 45 years undergoing surgery for stage I PTC (no distant metastases) were identified from the National Cancer Data Base (NCDB; 1998-2006) and from SEER 1988-2006 data. Multivariable models were used to examine the association of OS with the presence of lymph node metastases and number of metastatic nodes. In all, 47,902 patients in NCDB (11,740 with and 36,162 without nodal metastases) and 21,855 in the SEER database (5,188 with and 16,667 without nodal metastases) were included. After adjustment, OS was compromised for patients with nodal metastases compared with patients who did not have them (NCDB: hazard ratio (HR), 1.32; 95% CI, 1.04 to 1.67; P = .021; SEER: HR, 1.29; 95% CI, 1.08 to 1.56; P = .006). After adjustment, increasing number of metastatic lymph nodes was associated with decreasing OS up to six metastatic nodes (HR, 1.12; 95% CI, 1.01 to 1.25; P = .03), after which more positive nodes conferred no additional mortality risk (HR, 0.99; 95% CI, 0.99 to 1.05; P = .75). Our results suggest that cervical lymph node metastases are associated with compromised survival in young patients, warranting consideration of revised American Joint Committee on Cancer staging. A change point of six or fewer metastatic lymph nodes seems to carry prognostic significance, thus advocating for rigorous preoperative screening for nodal metastases. © 2015 by American Society of

  20. Age shall not weary us: deleterious effects of self-regulation depletion are specific to younger adults.

    Directory of Open Access Journals (Sweden)

    Theresa Dahm

    Full Text Available Self-regulation depletion (SRD, or ego-depletion, refers to decrements in self-regulation performance immediately following a different self-regulation-demanding activity. There are now over a hundred studies reporting SRD across a broad range of tasks and conditions. However, most studies have used young student samples. Because prefrontal brain regions thought to subserve self-regulation do not fully mature until 25 years of age, it is possible that SRD effects are confined to younger populations and are attenuated or disappear in older samples. We investigated this using the Stroop color task as an SRD induction and an autobiographical memory task as the outcome measure. We found that younger participants (<25 years were susceptible to depletion effects, but found no support for such effects in an older group (40-65 years. This suggests that the widely-reported phenomenon of SRD has important developmental boundary conditions casting doubt on claims that it represents a general feature of human cognition.

    version of the British Ability Scale-II (BAS-II) (standardised mean difference (SMD) 0.74, 95% confidence interval (CI) 0.48 to 1.00, 256 participants, 1 study, very low-quality evidence). This study did not measure other variables relevant to this review. The single study included in this review provides limited evidence on the effects of centre-based day care for children younger than five years of age in low- and middle-income countries. This study was at high risk of bias and may have limited generalisability to other low- and middle-income countries. Many of the studies excluded from this review paired day care attendance with co-interventions that are unlikely to be provided in normal day care centres. Effectiveness studies on centre-based day care without these co-interventions are few, and the need for such studies is significant. In future studies, comparisons might include home visits or alternative day care arrangements.

    Background The associations of optimal levels of all major cardiovascular disease (CVD) risk factors, i.e., low-risk, in younger age with subsequent CVD morbidity and mortality have been well documented. However, little is known about associations of low-risk profiles in younger age with functional disability in older age. Methods and Results The sample included 6,014 participants from the CHA Study. Low-risk status, defined as untreated SBP/DBP ≤120/≤80 mmHg, untreated serum total cholesterol fashion with less favorable risk-factor groups (p-trend <0.001). Compared to those with 2+ high-risk factors, the multivariable-adjusted odds of having any disability in ADLs vs. no disability in persons with low-risk, any moderate-risk, and 1 high-risk factor at baseline were lower by 58%, 48%, and 37%, respectively. Results were similar for IADLs, in both men and women. Conclusions Having an optimal CVD risk factor profile at younger age is associated with the lowest rate of functional disability in older age.

    The EML4-ALK fusion gene has recently been identified as a driver mutation in a subset of non-small cell lung cancers. In subsequent studies, EML4-ALK has been detected in a low percentage of patients, and was associated with a lack of EGFR or KRAS mutations, younger age, and adenocarcinoma with acinar histology. Cases with the EML4-ALK fusion gene were examined to clarify the clinicopathological characteristics of young adenocarcinoma patients. Between December 1998 and May 2009, 85 patients aged ≤ 50 with lung adenocarcinoma were treated at our hospital. We examined 49 samples from adenocarcinoma patients who underwent surgical resection, chemotherapy, and/or radiotherapy for the EML4-ALK gene. None of the patients received ALK inhibitors because these drugs had not been approved in Japan before 2012. EML4-ALK fusion genes were screened using multiplex reverse-transcription PCR assay, and were confirmed by direct sequencing. The EML4-ALK fusion gene was detected in five tumors (10.2%). One patient had stage IB disease, one had stage IIIA, and three had stage IV. Histologically, there was one solid adenocarcinoma, two acinar adenocarcinomas, and two papillary adenocarcinomas. EML4-ALK fusion genes were mutually exclusive to EGFR and KRAS mutations. The five-year survival rate was 59.4% in patients without EML4-ALK fusion and was not reached in patients with EML4-ALK fusion. The EML4-ALK fusion gene may be a strong oncogene in younger patients with lung adenocarcinoma. © 2018 The Authors.

  4. Aging and physiological changes of the kidneys including changes in glomerular filtration rate.

    2011-01-01

    In addition to the structural changes in the kidney associated with aging, physiological changes in renal function are also found in older adults, such as decreased glomerular filtration rate, vascular dysautonomia, altered tubular handling of creatinine, reduction in sodium reabsorption and potassium secretion, and diminished renal reserve. These alterations make aged individuals susceptible to the development of clinical conditions in response to usual stimuli that would otherwise be compensated for in younger individuals, including acute kidney injury, volume depletion and overload, disorders of serum sodium and potassium concentration, and toxic reactions to water-soluble drugs excreted by the kidneys. Additionally, the preservation with aging of a normal urinalysis, normal serum urea and creatinine values, erythropoietin synthesis, and normal phosphorus, calcium and magnesium tubular handling distinguishes decreased GFR due to normal aging from that due to chronic kidney disease.

  6. A multi-level analysis of the effects of age and gender stereotypes on trust in anthropomorphic technology by younger and older adults.

    Pak, Richard; McLaughlin, Anne Collins; Bass, Brock

    2014-01-01

    Previous research has shown that gender stereotypes, elicited by the appearance of the anthropomorphic technology, can alter perceptions of system reliability. The current study examined whether stereotypes about the perceived age and gender of anthropomorphic technology interacted with reliability to affect trust in such technology. Participants included a cross-section of younger and older adults. Through a factorial survey, participants responded to health-related vignettes containing anthropomorphic technology with a specific age, gender, and level of past reliability by rating their trust in the system. Trust in the technology was affected by the age and gender of the user as well as its appearance and reliability. Perceptions of anthropomorphic technology can be affected by pre-existing stereotypes about the capability of a specific age or gender. The perceived age and gender of automation can alter perceptions of the anthropomorphic technology such as trust. Thus, designers of automation should design anthropomorphic interfaces with an awareness that the perceived age and gender will interact with the user’s age and gender

  7. Age, composition, and areal distribution of the Pliocene Lawlor Tuff, and three younger Pliocene tuffs, California and Nevada

    The Lawlor Tuff is a widespread dacitic tephra layer produced by Plinian eruptions and ash flows derived from the Sonoma Volcanics, a volcanic area north of San Francisco Bay in the central Coast Ranges of California, USA. The younger, chemically similar Huichica tuff, the tuff of Napa, and the tuff of Monticello Road sequentially overlie the Lawlor Tuff, and were erupted from the same volcanic field. We obtain new laser-fusion and incremental-heating 40Ar/39Ar isochron and plateau ages of 4.834 ± 0.011, 4.76 ± 0.03, ≤4.70 ± 0.03, and 4.50 ± 0.02 Ma (1 sigma), respectively, for these layers. The ages are concordant with their stratigraphic positions and are significantly older than those determined previously by the K-Ar method on the same tuffs in previous studies.Based on offsets of the ash-flow phase of the Lawlor Tuff by strands of the eastern San Andreas fault system within the northeastern San Francisco Bay area, total offset east of the Rodgers Creek–Healdsburg fault is estimated to be in the range of 36 to 56 km, with corresponding displacement rates between 8.4 and 11.6 mm/yr over the past ∼4.83 Ma.We identify these tuffs by their chemical, petrographic, and magnetic characteristics over a large area in California and western Nevada, and at a number of new localities. They are thus unique chronostratigraphic markers that allow correlation of marine and terrestrial sedimentary and volcanic strata of early Pliocene age for their region of fallout. The tuff of Monticello Road is identified only near its eruptive source.

  8. A close or positive margin after mastectomy is not an indication for chest wall irradiation except in women aged fifty or younger

    Purpose: Indications for postmastectomy radiation include primary tumor size > 5 cm and ≥ 4 positive axillary nodes. In clinical practice, patients with a close or positive margin after mastectomy are also often treated with postmastectomy radiation. However, there is little data regarding the risk of a chest wall recurrence in patients with this pathologic feature who otherwise would be considered low risk (tumor size 25% at 8 years: Age ≤ 50 years was 28% vs. 0% for age > 50 (p=0.08). There was no correlation with chest wall failure and number of nodes, ER status, lymphovascular invasion, location of primary, grade, family history or type of tumor close to the margin. All four chest wall failures were in patients who had received adjuvant systemic chemotherapy ± Tamoxifen. Chest wall failures occurred in patients with margins within 1-2 mm in three patients and 5 mm in one patient. The cumulative chest wall recurrence at 8 years by margin proximity was 24% ≤ 2mm vs. 7% 2.1-6 mm (p=0.44), and by clinical size 24% for T2 tumors vs. 7% for T1 (p=0.55). Conclusions: A close or positive margin is uncommon (< 5%) after mastectomy in patients with tumor size < 5 cm and 0-3 positive axillary nodes, but when present it appears to be in a younger patient population. The subgroup of patients aged 50 or younger with clinical T1-T2 tumor size and 0-3 positive nodes who have a close (≤ 5 mm) or positive mastectomy margin are at high risk (28% at 8 years) for chest wall recurrence regardless of adjuvant systemic therapy, and therefore we recommend they be considered for postmastectomy radiation. This high risk of local failure was not observed in patients over age 50, suggesting this subgroup may not require adjuvant chest wall irradiation

    Full Text Available Plasmodium vivax is the most widespread parasite causing malaria, being especially prevalent in the Americas and Southeast Asia. Children are one of the most affected populations, especially in highly endemic areas. However, there are few studies evaluating the therapeutic response of infants with vivax malaria. This study retrospectively evaluated the parasitaemia clearance in children diagnosed with vivax malaria during the first five days of exclusive treatment with chloroquine (CQ. Infants aged less than six months old had a significantly slower parasitaemia clearance time compared to the group of infants and children between six months and 12 years old (Kaplan-Meier survival analysis; Wilcoxon test; p = 0.004. The impaired clearance of parasitaemia in younger children with vivax malaria is shown for the first time in Latin America. It is speculated that CQ pharmacokinetics in young children with vivax malaria is distinct, but this specific population may also allow the detection of CQ-resistant parasites during follow-up, due to the lack of previous immunity.

    Long-term local control rates were studied in a series of 659 patients with invasive breast cancer aged 40 years or younger, who underwent mastectomy in general hospitals in the southern part of the Netherlands between 1988 and 2005. During a median follow-up time of 6.0 years, 34 patients developed a local recurrence in the chest wall without previous or simultaneous evidence of distant disease. The 5- and 10-year actuarial local recurrence rates for the total group were 5.6% (95% confidence interval [95% CI], 3.5-7.7%) and 7.3% (95% CI, 4.7-9.9%), respectively. A multivariate analysis showed that patients receiving radiotherapy (hazards ratio [HR], 0.29; 95% CI, 0.10-0.96) or adjuvant systemic treatment (HR 0.23; 95% CI, 0.08-0.65) had a significantly lower risk of local recurrence. It is concluded that excellent local control rates can be obtained with mastectomy in young women with breast cancer, especially in those who receive adjuvant systemic treatment and/or radiotherapy.

    The purpose of this study was to examine the independent influence of age on levels of HIV-related stigma experienced by adults living with HIV/AIDS. To accomplish this, cross-sectional data from the Ontario HIV Treatment Network Cohort Study were used to determine whether older age is associated with overall stigma among HIV-positive adults living in Ontario, Canada (n = 960). The relationship was also tested for enacted, anticipated, and internalized stigma. Covariates included sociodemographic (e.g., gender, sexual orientation, race) and psychosocial variables (e.g., depression). Modifying effects of covariates were also investigated. Those 55 and older have significantly lower overall and internalized stigma than adults under age 40, even when accounting for gender, sexual orientation, income, time since diagnosis, depression, maladaptive coping, and social support. Age does not predict enacted or Anticipated Stigma when accounting for the demographic and psychosocial variables. A significant interaction between depression and age suggests that stigma declines with age among those who are depressed but increases to age 50 and then decreases in older age groups among those who are not depressed. Age matters when it comes to understanding stigma among adults living with HIV/AIDS; however, the relationship between age and stigma is complex, varying according to stigma type and depression level.

    This study compared the incidence of rubella seronegativity among gravidae of 25 year-old and younger, between those born in Hong Kong after 1983 when the two-dose rubella vaccination was implemented, versus gravidae born before, to examine the impact of the two-dose regimen. In this retrospective cohort study, the incidence of antenatal rubella seronegativity in our parturients managed in1997-2015 was analysed by their age from ≤16 to 25 years, and the effect of year of birth was determined adjusting for confounding factors including teenage status, obstetric history, anthropometric factors, and health parameters including anaemia, thalassaemia trait and hepatitis B carrier status. Among the 12743 gravidae, the 6103 gravidae born after 1983 had overall higher rubella seronegativity (9.1% versus 4.4%, OR 2.061, 95% CI 1.797-2.364), with significant difference (p = 0.006) and inverse correlation (prubella seronegativity except for those of ≤16 years. Regression analysis confirmed that birth after 1983 was independently associated with rubella seronegativity (aOR 2.207, 95% CI 1.902-2.562). There was a significant trend between rubella seronegativity with age in young gravidae, but the pattern was opposite between gravidae born after versus in/before 1983, with the former having a higher incidence of seronegativity at all ages. Young women covered by the two-dose rubella immunisation programme have a paradoxically higher incidence of rubella seronegativity.

    We studied the association between type 1 diabetes with autoimmune thyroid disease (AITD) and A/G allele polymorphism in exon 1 of the CTLA-4 gene in a Japanese population. We studied 74 Japanese type 1 diabetic patients with or without AITD and 107 normal subjects to identify the association between CTLA-4 polymorphism and type 1 diabetes using polymerase chain reaction-restriction fragment length polymorphism analysis. The frequency of the CTLA-4 G allele differed significantly between the type 1 diabetic patients (61%) and the normal control subjects (48%) (P = 0.016). The difference in the CTLA-4 G allele became greater between patients with a younger age of onset of type 1 diabetes (age at onset frequency of the CTLA-4 G allele did not differ between type 1 diabetic patients with younger and older age of onset (64% vs. 57%). The G allele frequencies in the patients with younger-onset type 1 diabetes and AITD increased more than in the control patients (P = 0.025). These differences reflected a significant increase in the frequency of G/G genotype--that is, 54% in those with younger-onset type 1 diabetes and AITD, 39% in those without AITD, and 28% in control subjects. An association was detected between the CTLA-4 gene polymorphism and younger-onset type 1 diabetes with AITD. The G variant was suggested to be genetically linked to AITD-associated type 1 diabetes of younger onset in this apanese population. The defect in these patients presumably lies in a T-cell-mediated autoimmune mechanism.

    Full Text Available Background. Mixed findings in biobehavioral research on heart disease may partly be attributed to age-related differences in the prognostic value of psychological distress. This study sought to test the hypothesis that Type D (distressed personality contributes to an increased mortality risk following implantable cardioverter defibrillator (ICD treatment in younger patients but not in older patients. Methods. The Type D Scale (DS14 was used to assess general psychological distress in 455 younger (≤70 y,. Cardiac resynchronization therapy (CRT, but not Type D personality, was associated with increased mortality in older patients. Among younger patients, however, Type D personality was associated with an adjusted hazard ratio = 1.91 (95% CI 1.09–3.34 and 2.26 (95% CI 1.16–4.41 for all-cause and cardiac mortality; other predictors were increasing age, CRT, appropriate shocks, ACE-inhibitors, and smoking. Conclusion. Type D personality was independently associated with all-cause and cardiac mortality in younger ICD patients but not in older patients. Cardiovascular research needs to further explore age-related differences in psychosocial risk.

    Purpose: The association between radiotherapy for gynecological carcinoma and sexual dysfunction is well established. Regular vaginal dilation is widely recommended to these women as a way for them to maintain vaginal health and good sexual functioning. However, the compliance rate with this recommendation is low. The purpose of this study was to test the effectiveness of a group psychoeducational program based on the 'information-motivation-behavioral skills' model of behavior change in increasing the rate of compliance. Methods and Materials: Thirty-two women with Stage I or II cervical or endometrial carcinoma who were being treated with radiotherapy were randomized and received either the experimental group program or the control intervention that consisted of written information and brief counseling. Outcome measures included global sexual health, knowledge about sexuality and cancer, fears about sexuality after cancer, and vaginal dilation compliance. Results: Younger women attending the experimental program (44.4%) were significantly more likely to follow recommendations for vaginal dilation than those who received the control intervention (5.6%). Women, regardless of age, who received the experimental intervention reported less fear about sex after cancer treatment. The older women who received the experimental intervention gained more sexual knowledge. There was no evidence that the experimental intervention improved global sexual health. Conclusions: This is the first controlled study to provide evidence of an intervention's effectiveness 1. in increasing women's vaginal dilation following radiotherapy for gynecological carcinoma and 2. in reducing their fears about sex after cancer. Most women, particularly younger women, are unlikely to follow the recommendation to dilate unless they are given assistance in overcoming their fears and taught behavioral skills

    The aim of this study is to detect the accuracy rate of emergency physicians' (EPs') interpretations of cranial computed tomography (CT) of a special patient group, the patients younger than the age of 2 years with mild head trauma. The study took place in a research and training hospital within a period of 3 months and included a total of 156 patients. The scans were interpreted by the EPs, and the predicted results were recorded in the patients' files; simultaneous interpretations of the on-call radiologist were also recorded. The interpretations were scanned retrospectively at the end of each month, compared, and recorded. With reference to the radiologists' reports, the sensitivity and the specificity of EPs' interpretations of cranial CT were 76.9% and 95.1%, respectively. Concordance of both groups' interpretations was 93.6%. The area under the curve (AUC) value in receiver operating characteristic (ROC) analysis, which reflects these results, was calculated as 0.860 (95% confidence interval, 0.740-0.981). This value was found to be statistically significant (P mild head trauma, until the radiologists' reports are obtained. However, the anatomic diversities of these patients' age group should be taken into consideration. Copyright © 2015 Elsevier Inc. All rights reserved.

    Scalds are a common injury in children and a frequent reason for hospitalisation despite being a preventable injury. This retrospective two year study reports data from 730 children aged 14 years or younger who sustained a scald between 2009 and 2010 and were admitted to a burns centre in Australia or New Zealand. Data were extracted from the Burn Registry of Australia and New Zealand (BRANZ), which included data from 13 burns centres in Australia and New Zealand. Scald injury contributed 56% (95% CI 53-59%) of all pediatric burns. There were two high risk groups; male toddlers age one to two, contributing 34% (95% CI 31-38%) of all scalds, and indigenous children who were over 3 times more likely to experience a scald requiring admission to a burns unit than their non-indigenous peers. First aid cooling by non-professionals was initiated in 89% (95% CI 86-91%) of cases but only 20% (95% CI 16-23%) performed it as recommended. This study highlights that effective burn first aid reduces hospital stay and reinforces the need to encourage, carers and bystanders to deliver effective first aid and the importance of targeted prevention campaigns that reduce the burden of pediatric scald burns in Australia and New Zealand.

    Young, active candidates for total shoulder arthroplasty (TSA) are a unique group of patients. Not only do they demand longevity and improved function, but they also desire a return to physical activities. To determine the rate of return to sports in patients aged ≤55 years undergoing TSA. Case series; Level of evidence, 4. This was a retrospective review of consecutive patients who underwent anatomic TSA at a single institution. Exclusion criteria included age at the time of surgery >55 years and sports questionnaire, American Shoulder and Elbow Surgeons (ASES) score, and visual analog scale (VAS) score. From 70 eligible patients, 59 patients (61 shoulders) were included with an average follow-up of 61.0 months (range, 25-103 months) and average age at the time of surgery of 48.9 years (range, 25-55 years). The average VAS score improved from 5.6 to 0.9 ( P sports. Moreover, patients in 96.4% of shoulders (55/57) restarted at least 1 sport at an average of 6.7 months. Direct rates of return were as follows: fitness sports (97.2%), golf (93.3%), singles tennis (87.5%), swimming (77.7%), basketball (75.0%), and flag football (66.7%). Patients in 47 shoulders (82.4%) returned to a similar or higher level of sports; 90.3% returned to high-demand sports, and 83.8% returned to high upper extremity sports. There was no significant difference in rates of return to sports by body mass index, sex, age, preoperative diagnosis, revision status, and dominant extremity. In patients aged ≤55 years undergoing TSA, there was a 96.4% rate of return to ≥1 previous sports at an average of 6.7 months. Furthermore, at an average follow-up of 61.0 months, no patients needed revision of their glenoid component, despite an 83.8% rate of return to high upper extremity sports. While caution should still be advised in young, active patients undergoing TSA, these results demonstrate a high satisfaction rate and improved ability to return to most sports after surgery.

    This paper proposes a new approach to Ageing Probabilistic Safety Assessment (APSA) modelling, which is intended to be used to support risk-informed decisions on the effectiveness of maintenance management programs and technical specification requirements of critical equipment of Nuclear Power Plants (NPP) within the framework of the Risk Informed Decision Making according to R.G. 1.174 principles. This approach focuses on the incorporation of not only equipment ageing but also effectiveness of maintenance and efficiency of surveillance testing explicitly into APSA models and data. This methodology is applied to a motor-operated valve of the auxiliary feed water system (AFWS) of a PWR. This simple example of application focuses on a critical safety-related equipment of a NPP in order to evaluate the risk impact of considering different approaches to APSA and the combined effect of equipment ageing and maintenance and testing alternatives along NPP design life. The risk impact of several alternatives in maintenance strategy is discussed

    Older adults display alterations in neural reflections of conflict-related processing. We examined response times (RTs), error rates, and event-related potential (ERP; N2 and P3 components) indices of conflict adaptation (i.e., congruency sequence effects) a cognitive control process wherein previous-trial congruency influences current-trial performance, along with post-error slowing, correct-related negativity (CRN), error-related negativity (ERN) and error positivity (Pe) amplitudes in 65 healthy older adults and 94 healthy younger adults. Older adults showed generalized slowing, had decreased post-error slowing, and committed more errors than younger adults. Both older and younger adults showed conflict adaptation effects; magnitude of conflict adaptation did not differ by age. N2 amplitudes were similar between groups; younger, but not older, adults showed conflict adaptation effects for P3 component amplitudes. CRN and Pe, but not ERN, amplitudes differed between groups. Data support generalized declines in cognitive control processes in older adults without specific deficits in conflict adaptation. Copyright © 2016 Elsevier B.V. All rights reserved.

    The present work investigated associations of older people with humanness. Focusing on complementary approaches (attribute-based, metaphor-based, and target-based), 4 studies tested the hypothesis that older people are the targets of animalistic dehumanization. Using an emotional attribution task, Study 1 (N = 112) explored infrahumanization and shows that young participants attributed more uniquely human emotions to young people than to older ones. No such effect occurred with regards to nonuniquely human emotions. Results of Study 2 (N = 62) replicated this result using a lexical-decision task. Using the metaphor-based approach, Study 3 (N = 99) confirmed that older people's dehumanization is restricted to its animalistic form and does not extend to the mechanistic one. Finally, in Study 4 (N = 167), we used a target-based approach and showed that characteristics initially attributed to older people are perceived as denoting lesser humanness than when these same characteristics are associated with younger people. Results of the 4 studies provide evidence for an animalistic form of dehumanization of older people by younger ones. Limits, implications, and future research are discussed.

    Full Text Available Abstract Background Lung cancer in young patients (less or equal to 45 years is uncommon and has clinical characteristics different from that in older patients. We investigated the outcomes and prognostic factors of young patients with advanced non-small cell lung cancer (NSCLC. Methods From January 2000 to December 2009, we enrolled patients aged ≤45 years and diagnosed with stage IIIB or IV NSCLC. Their clinical data, including age, gender, performance status, histologic types, disease stages, laboratory data at diagnosis, treatment modalities, and survival were reviewed and analyzed. A Cox proportional hazard model was used to calculate the hazard ratio (HR and its 95% confidence interval (CI. Results A total of 144 patients with advanced NSCLC were included. Female patients were more prevalent (n = 74, 51.4%. Adenocarcinoma was the most common histologic type (n = 119, 82.6% in both genders (male, n = 54, 77.1%; female, n = 65, 87.8%. Epidermal growth factor receptor (EGFR sequences were determined using tumor specimens from 58 patients, and 29 showed an EGFR mutation. No significant difference in median survival was found between patient groups with and without the EGFR mutation (798 vs. 708 days, p = 0.65. In multivariate analysis, male gender (HR, 1.70; 95% CI: 1.08-2.68, body mass index (BMI less than 25 kg/m2 (HR, 2.72; 95% CI: 1.39-5.30, stage IV disease (HR, 2.62; 95% CI: 1.50-4.57, and anemia (HR, 2.08; 95% CI: 1.15-3.77 were associated with a short survival time. Conclusions Low BMI, stage IV disease, anemia at diagnosis, and male gender were the negative prognostic factors for young patients with advanced NSCLC.

    To determine the prevalence of acute lower respiratory tract infections and the risk factors associated with living conditions among children up to 5 years of age in the city of Rio Grande, in the state of Rio Grande do Sul, Brazil. A population-based cross-sectional study was carried out with 775 children. A standardized questionnaire was administered to the mother or other caregiver at the child's home in order to collect information on housing conditions, socioeconomic status, and smoking in the home. Additional variables examined included nutritional status, duration of breast-feeding, prenatal care, and utilization of health care services. Environmental variables were analyzed individually and were also grouped together in an "environmental score" that encompassed 10 variables: type of house construction, type of floor, home heating system, type of stove, dog in the child's room, dog in the house, cat in the child's room, cat in the house, number of people per room, and maternal smoking. The grouped environmental score ranged from 0 (best) to 10 (worst). The analysis included two stages: a bivariate stage, in which the prevalence ratio was calculated for each risk factor, and a multivariate stage, with logistic regression. The overall prevalence of acute lower respiratory tract infections was 23.9%. The main risk factors identified were: environmental score >/= 3 points, maternal schooling or = 30 years was found to protect against the development of respiratory illness. Specific programs need to be implemented to control acute respiratory illnesses in the population studied. In future studies with this population, the environmental score that we developed could be used in place of the complete set of environmental variables that we tested. This environmental score should be applied in other contexts so as to determine its external validity.

    Background Younger survivors (YS) of breast cancer often report more survivorship symptoms such as fatigue, depression, sexual difficulty, and cognitive problems than older survivors (OS). We sought to determine the effect of breast cancer and age at diagnosis on Quality of Life (QoL) by comparing 3 groups: 1) YS diagnosed at age 45 or before, 2) OS diagnosed between 55 and 70, and, 3) for the YS, age-matched controls (AC) of women not diagnosed with breast cancer. Methods Using a large Eastern Cooperative Oncology Group (ECOG) data base, we recruited 505 YS who were ages 45 or younger when diagnosed and 622 OS diagnosed at 55 to 70. YS, OS, and AC were compared on physical, psychological, social, spiritual, and overall QoL variables. Results Compared to both AC and to OS, YS reported more depressive symptoms (p=.005) and fatigue (p<.001), poorer self-reported attention function (p<.001), and poorer sexual function (p<.001) than either comparison group. However, YS also reported a greater sense of personal growth (p<.001) and perceived less social constraint (p<.001) from their partner than AC. Conclusions YS reported worse functioning than AC relative to depression, fatigue, attention, sexual function, and spirituality. Perhaps even more important, YS fared worse than both AC and OS on body image, anxiety, sleep, marital satisfaction, and fear of recurrence, indicating that YS are at greater risk for long term QoL problems than survivors diagnosed at a later age.

    Previous epidemiological studies have consistently found a positive family history of esophageal cancer is associated with a significantly increased risk of the cancer. However, whether the elevated risk could be attributed to common household exposure or inherited susceptibility is uncertain. This study aimed to highlight the effect of genetic predisposition by noting the significant differences in onset age and multiple primary cancers between esophageal squamous cell carcinoma (ESCC) cases with or without a positive family history of the cancer. Age at onset and the percentage of multiple primary cancers were compared between ESCCs with (n = 766) or without (n = 1 776) a positive family history of the cancer in a consecutive surgery cohort at the Department of Thoracic Surgery of Hebei Tumor Hospital and the Fourth Hospital of Hebei Medical University. Overall, ESCCs with a positive family history of the cancer featured both a significantly younger age of onset and significantly more multiple primary cancers than those with a negative family history (onset age 51.83 vs. 53.49 years old, P genetic predisposition. The results of subgroup analyses indicate a younger age of ESCC development results from the interaction of environmental and genetic risk factors, but multiple primary cancers may be related only to genetic predisposition.

    To develop the Mini-Manual Ability Classification System (Mini-MACS) and to evaluate the extent to which its ratings are valid and reliable when children younger than 4 years are rated by their parents and therapists. The Mini-MACS was created by making adjustments to the MACS. The development involved a pilot project, consensus discussions within an expert group, and the creation of a test version of the Mini-MACS that was evaluated for content validity and interrater reliability. A convenience sample of 61 children with signs of cerebral palsy aged 12 to 51 months (mean age 30.2mo [SD 10.1]) were classified by one parent and two occupational therapists across a total of 64 assessments. Agreement between the parents' and therapists' ratings was evaluated using the intraclass correlation coefficient (ICC) and the percentage of agreement. The first sentence of the five levels in the MACS was kept, but other descriptions within the Mini-MACS were adjusted to be more relevant for the younger age group. The ICC between parents and therapists was 0.90 (95% confidence interval [CI] 0.79-0.92), and for the two therapists it was 0.97 (95% CI 0.78-0.92). Most parents and therapists found the descriptions in the Mini-MACS suitable and easy to understand. The Mini-MACS seems applicable for children from 1 to 4 years of age. © 2016 Mac Keith Press.

    INTRODUCTION: Lung cancer remains a leading cause of cancer-related death. The incidence increases with age and the occurrence in young patients is relatively low. The clinicopathological features of lung cancer in younger patients have not been fully explored previously. METHODS: To assess the age...... differences in the clinical characteristics of lung cancer, we conducted a retrospective analysis comparing young patients ≤ 65 years of age with an elderly group > 65 years of age. Among 1,232 patients evaluated due to suspicion of lung cancer in our fast-track setting from January-December 2013, 312 newly...... diagnosed lung cancer patients were included. RESULTS: Patients ≤ 65 years had a significantly higher representation of females (p = 0.0021), more frequent familial cancer aggregation (p = 0.028) and a lower incidence of squamous cell carcinoma (p = 0.0133). When excluding pure carcinoid tumours...

    This analysis describes the impact of hysterectomy on incidence rates and trends in endometrioid endometrial cancer in the United States among women of reproductive age. Hysterectomy prevalence for states containing Surveillance, Epidemiology, and End Results (SEER) registry was estimated using data from the Behavioral Risk Factor Surveillance System (BRFSS) between 1992 and 2010. The population was adjusted for age, race, and calendar year strata. Age-adjusted incidence rates and trends of endometrial cancer among women age 20-49 corrected for hysterectomy were estimated. Hysterectomy prevalence varied by age, race, and ethnicity. Increasing incidence trends were observed, and were attenuated after correcting for hysterectomy. Among all women, the incidence was increasing 1.6% annually (95% CI 0.9, 2.3) and this increase was no longer significant after correction for hysterectomy (+ 0.7; 95% CI - 0.1, 1.5). Stage at diagnosis was similar with and without correction for hysterectomy. The largest increase in incidence over time was among Hispanic women; even after correction for hysterectomy, incidence was increasing (1.8%; 95% CI 0.2, 3.4) annually. Overall, endometrioid endometrial cancer incidence rates in the US remain stable among women of reproductive age. Routine reporting of endometrial cancer incidence does not accurately measure incidence among racial and ethnic minorities.

    To investigate the potential benefits of testosterone administration to elderly men (>65 years) with late-onset hypogonadism (LOH) in comparison with younger men and to assess the safety of testosterone administration to elderly men. A total of 561 hypogonadal men from two registry studies were divided into age groups of ≤65 years (group Y, n=450; range, 32-65 years) and >65 years (group O, n=111; range, 66-84 years). Following an initial 6-week interval, all men were treated with 3-month injections of parenteral testosterone undecanoate for up to 6 years. Over the 6 years, there was a progressive decrease of body weight and waist circumference. Beneficial effects on lipids and other metabolic factors and on psychological and sexual functioning progressed over the first 24 to 42 months and were sustained. Rather than a deterioration, there was an improvement of urinary parameters. Prostate volume and prostate-specific antigen increased moderately. Hematocrit levels increased but remained within safe margins. The benefits of restoring serum testosterone in men with LOH were not significantly different between men older than 65 years of age and younger men. There were no indications that side effects were more severe in elderly men. The effects on prostate and urinary function and hematocrit were within safe margins. Age itself need not be a contraindication to testosterone treatment of elderly men with LOH.

    OBJECTIVE The risk of venous thromboembolism (VTE) from deep venous thrombosis (DVT) is significant in neurosurgical patients. VTE is considered a leading cause of preventable hospital deaths and preventing DVT is a closely monitored quality metric, often tied to accreditation, hospital ratings, and reimbursement. Adult protocols include prophylaxis with anticoagulant medications. Children's hospitals may adopt adult protocols, although the incidence of DVT and the risk or efficacy of treatment is not well defined. The incidence of DVT in children is likely less than in adults, although there is very little prospectively collected information. Most consider the risk of DVT to be extremely low in children 12 years of age or younger. However, this consideration is based on tradition and retrospective reviews of trauma databases. In this study, the authors prospectively evaluated pediatric patients undergoing a variety of elective neurosurgical procedures and performed Doppler ultrasound studies before and after surgery. METHODS A total of 100 patients were prospectively enrolled in this study. All of the patients were between the ages of 1 month and 12 years and were undergoing elective neurosurgical procedures. The 91 patients who completed the protocol received a bilateral lower-extremity Doppler ultrasound examination within 48 hours prior to surgery. Patients did not receive either medical or mechanical DVT prophylaxis during or after surgery. The ultrasound examination was repeated within 72 hours after surgery. An independent, board-certified radiologist evaluated all sonograms. We prospectively collected data, including potential risk factors, details of surgery, and details of the clinical course. All patients were followed clinically for at least 1 year. RESULTS There was no clinical or ultrasound evidence of DVT or VTE in any of the 91 patients. There was no clinical evidence of VTE in the 9 patients who did not complete the protocol. CONCLUSIONS In this

    Younger survivors (YS) of breast cancer often report more survivorship symptoms such as fatigue, depression, sexual difficulty, and cognitive problems than older survivors (OS). This study sought to determine the effect of breast cancer and age at diagnosis on quality of life (QoL) by comparing 3 groups: 1) YS diagnosed at age 45 years or before, 2) OS diagnosed between 55 and 70, and 3) for the YSs, age-matched controls (AC) of women not diagnosed with breast cancer. Using a large Eastern Cooperative Oncology Group (ECOG) database, 505 YS were recruited who were aged 45 years or younger when diagnosed and 622 OS diagnosed at 55 to 70 years of age. YS, OS, and AC were compared on physical, psychological, social, spiritual, and overall QoL variables. Compared to both AC and to OS, YS reported more depressive symptoms (P = .005) and fatigue (P < .001), poorer self-reported attention function (P < .001), and poorer sexual function (P < .001) than either comparison group. However, YS also reported a greater sense of personal growth (P < .001) and perceived less social constraint (P < .001) from their partner than AC. YS reported worse functioning than AC relative to depression, fatigue, attention, sexual function, and spirituality. Perhaps even more important, YS fared worse than both AC and OS on body image, anxiety, sleep, marital satisfaction, and fear of recurrence, indicating that YS are at greater risk for long-term QoL problems than survivors diagnosed at a later age. © 2014 American Cancer Society.

    To assist in the long-term health management of residents and evaluate the health impacts after the Tokyo Electric Power Company's Fukushima Daiichi Nuclear Power Plant accident in Fukushima Prefecture, the Fukushima prefectural government decided to implement the Fukushima Health Management Survey. This report describes the results for residents aged 15 years or younger who received health checks and evaluates the data obtained from 2011 and 2012. The target group consisted of residents aged 15 years or younger who had lived in the evacuation zone. The health checks were performed on receipt of an application from any of the residents. The checks, which included the measurements of height, weight, blood pressure, biochemical laboratory findings, and peripheral blood findings, were performed as required. 1) A total of 17,934 (64.5%) and 11,780 (43.5%) residents aged 15 years or younger received health checks in 2011 and 2012, respectively. 2) In both years, a number of male and female residents in the 7-15 year age group were found to suffer from obesity, hyperlipidemia, hyperuricemia, or liver dysfunction. Furthermore, pediatric aged 15 years or younger were commonly observed to suffer from hypertension or glucose metabolic abnormalities. 3) A comparison of data from 2012 and 2011 demonstrated that both males and females frequently showed increased body height and decreased body weight in 2012. The prevalence of hypertension, glucose metabolic abnormalities, or high γ-GTP values in males and females in the 7-15 year age group in 2012 was lower than that in 2011. However, the prevalence of hyperuricemia among residents in the 7-15 year age group was higher in 2012 than in 2011. These results suggested that some residents aged 15 years or under who had lived in the evacuation zone had developed obesity, hyperlipidemia, hyperuricemia, liver dysfunction, hypertension, or glucose metabolic abnormalities. Therefore, we think that it is necessary to continue the health

    Purpose: The aim of this study was to investigate whether patients <35 years old have similar risk of locoregional recurrence after breast conservation therapy compared with patients 35 to 40 years old. Methods and materials: We retrospectively reviewed records of 196 consecutive patients ≤40 years old who received breast conservation therapy (BCT) from 1987 to 2000 for breast cancer and compared outcomes between patients <35 years old with patients 35 to 40 years old. The majority of patients received neoadjuvant chemotherapy as part of their treatment. Multivariate analysis was performed to assess risk factors for locoregional recurrence. Results: After a median follow-up of 64 months, 22 locoregional recurrences (LRR) were observed. Twenty patients developed locoregional recurrence as their first site of relapse. Two patients had bone-only metastases before their locoregional recurrence. On multivariate analysis, age <35 years was associated with a statistically significant increased risk of locoregional recurrence. The 5-year rate of locoregional control was 87.9% in patients <35 years old compared with 91.7% in patients 35 to 40 years old (p = 0.042). Conclusions: Our finding supports an increased risk of locoregional recurrence as a function of younger age after breast conservation therapy, even among young patients 40 years old and younger

    Lung cancer epidemics emerged first among males in European countries in the first half of the 20th century and then among females in the second half. We have explored the recent convergence in sex ratios. Age-standardized (world standard) lung cancer mortality rates at ages 20 to 44 years were derived from WHO for 26 countries separately from the beginning of their data series to 2002. The most recent periods in which trends could be adequately represented as linear were determined using the software package 'Joinpoint'. Countries were classified by their statistically significant trends for each sex in these periods. Lung cancer mortality among young adult males tended to decrease. Among females there were significant recent increases in eight ('Pattern 1') countries and no significant trend in 16 ('Pattern 2') countries. Rates decreased in both sexes in the UK and rose in both sexes in Portugal. The extent to which sex ratios had actually converged by 2002 varied widely, with values still above 3 in six eastern countries and below 1 in Scandinavia, the Netherlands and Ireland. At the beginning of 21st century, there is a general tendency for sex ratios for lung cancer mortality to converge towards 1, but with considerable variation in the extent to which such convergence has been realized.

    Recent studies have shown a discrepancy between traditional functional outcomes and patient satisfaction, with some reporting less than 85% satisfaction in older patients undergoing total knee arthroplasty (TKA). As native knee biomechanics are not completely replicated, the resulting functional limitations may cause dissatisfaction in higher-demand individuals. Few studies have recorded patient-reported outcomes, health-related quality of life scores, and patient satisfaction in a young population undergoing TKA. One hundred thirty-six primary TKAs were performed in 114 patients aged 50 years or younger (mean age, 47.0 years; range, 30-50 years) at a single institution. The main diagnoses were osteoarthritis (85%) and rheumatoid arthritis (10%). The range of motion, Knee Society Score, Oxford Knee Score, and Physical and Mental Component Scores of Short Form-36 increased significantly (P patients had good/excellent knee scores, 71.3% had good/excellent function scores, 94.9% met the minimal clinically important difference for the Oxford Knee Score, and 84.6% met the minimal clinically important difference for the Physical Component Score. We found that 88.8% of patients were satisfied with their surgeries, whereas 86.8% had their expectations fulfilled. Survivorship using revision as an end point was 97.8% at a mean of 7 years (range, 3-16 years). Patients aged 50 years or younger undergoing TKA can experience significant improvements in their quality of life, have their expectations met, and be satisfied with their surgeries, at rates similar to those of non-age-restricted populations. Surgeons should inform them of these benefits and the potential risk of revision surgery in the future, albeit increasingly shown to be low. Copyright © 2016 Elsevier Inc. All rights reserved.

    The aim of this study was to evaluate by clinical and laboratory parameters how cystic fibrosis (CF) affects growth and nutritional status of children who were undergoing CF treatment but did not receive newborn screening. A historical cohort study of 52 CF patients younger than 10 years of age were followed in a reference center in Campinas, Southeast Brazil. Anthropometric measurements were abstracted from medical records until March/2010, when neonatal screening program was implemented. Between September/2009 and March/2010, parental height of the 52 CF patients were also measured. Regarding nutritional status, four patients had Z-scores ≤ -2 for height/age (H/A) and body mass index/age (BMI/A). The following variables were associated with improved H/A ratio: fewer hospitalizations, longer time from first appointment to diagnosis, longer time from birth to diagnosis and later onset of respiratory disease. Forced vital capacity [FVC(%)], forced expiratory flow between 25-75% of FVC [FEF25-75(%)], forced expiratory volume in the first second [FEV1(%)], gestational age, birth weight and early respiratory symptoms were associated with IMC/A. Greater number of hospitalizations, diagnosis delay and early onset of respiratory disease had a negative impact on growth. Lower spirometric values, lower gestational age, lower birth weight, and early onset of respiratory symptoms had negative impact on nutritional status. Malnutrition was observed in 7.7% of cases, but 23% of children had nutritional risk. Copyright © 2014 Associação de Pediatria de São Paulo. Publicado por Elsevier Editora Ltda. All rights reserved.

    Full Text Available Abstract Background In Mexico, as in other developing countries, micronutrient deficiencies are common in infants between 6 and 24 months of age and are an important public health problem. The objective of this study was to determine the prevalence of anemia and of iron, folic acid, and zinc deficiencies in Mexican children under 2 years of age who use the health care services provided by the Mexican Institute for Social Security (IMSS. Methods A nationwide survey was conducted with a representative sample of children younger than 2 years of age, beneficiaries, and users of health care services provided by IMSS through its regular regimen (located in urban populations and its Oportunidades program (services offered in rural areas. A subsample of 4,955 clinically healthy children was studied to determine their micronutrient status. A venous blood sample was drawn to determine hemoglobin, serum ferritin, percent of transferrin saturation, zinc, and folic acid. Descriptive statistics include point estimates and 95% confidence intervals for the sample and projections for the larger population from which the sample was drawn. Results Twenty percent of children younger than 2 years of age had anemia, and 27.8% (rural to 32.6% (urban had iron deficiency; more than 50% of anemia was not associated with low ferritin concentrations. Iron stores were more depleted as age increased. Low serum zinc and folic acid deficiencies were 28% and 10%, respectively, in the urban areas, and 13% and 8%, respectively, in rural areas. The prevalence of simultaneous iron and zinc deficiencies was 9.2% and 2.7% in urban and rural areas. Children with anemia have higher percentages of folic acid deficiency than children with normal iron status. Conclusion Iron and zinc deficiencies constitute the principal micronutrient deficiencies in Mexican children younger than 2 years old who use the health care services provided by IMSS. Anemia not associated with low ferritin values

    Purpose: Optimal local management for young women with early-stage breast cancer remains controversial. This study examined 15-year outcomes among women younger than 40 years treated with breast-conserving surgery plus whole-breast radiation therapy (BCT) compared with those treated with modified radical mastectomy (MRM). Methods and Materials: Women aged 20 to 39 years with early-stage breast cancer diagnosed between 1989 and 2003 were identified in a population-based database. Primary outcomes of breast cancer–specific survival (BCSS), overall survival (OS) and secondary outcomes of local relapse–free survival (LRFS), locoregional relapse–free survival (LRRFS), and distant relapse–free survival (DRFS) were calculated using Kaplan-Meier methods and compared between BCT and MRM cohorts using log-rank tests. A planned subgroup analysis was performed on patients considered “ideal” for BCT (ie, T1N0, negative margins and no extensive ductal carcinoma in situ) and in whom local therapy may have the largest impact on survival because of low systemic risk. Results: 965 patients were identified; 616 had BCT and 349 had MRM. The median follow-up time was 14.4 years (range, 8.4-23.3 years). Overall, 15-year rates of BCSS (76.0% vs 74.1%, P=.62), OS (74.2% vs 73.0%, P=.75), LRFS (85.4% vs 86.5%, P=.95), LRRFS (82.2% vs 81.6%, P=.61), and DRFS (74.4% vs 71.6%, P=.40) were similar between the BCT and MRM cohorts. In the “ideal” for BCT subgroup, there were 219 BCT and 67 MRM patients with a median follow-up time of 15.5 years. The 15-year BCSS (86.1% vs 82.9%, P=.57), OS (82.6% vs 82.9%, P=.89), LRFS (86.2% vs 84.2%, P=.50), LRRFS (83.1% vs 78.3%, P=.24), and DRFS (84.8% vs 79.1%, P=.17) were similar in the BCT and MRM cohorts. Conclusions: This population-based analysis with long-term follow-up confirmed that women younger than 40 years treated with BCT had similar 15-year outcomes compared with MRM. Young age alone is not a contraindication to BCT.

    Research has shown that rear-seated children are 36 to 40 percent safer than front-seated children. Because of the substantial differences in traffic safety culture that appear to exist in rural areas and the limited research regarding seat placement and rurality, this study seeks to contribute to the safety literature by determining at what rate children are riding in the front seat and whether differences exist between rural and urban areas in regards to child front seat placement. Current child placement frequencies within vehicles were ascertained through direct observations of morning child drop-offs at randomly selected urban and rural elementary schools in eastern North Dakota during November and December of 2009, with a focus on children aged 12 or younger. Two observers wearing orange safety vests and carrying observation sheets were stationed at each elementary school a minimum of 45 min prior to each school's designated start time. Based on the vehicles that entered the school's parking lot/drop-off circle and from which a minimum of one child exited, observers were instructed to record vehicle type, presence of children in the front seat appearing to be younger than 13 years old, availability of room in the back seat, and placement of other children in the vehicle. During November and December of 2009 a total of 537 vehicles were observed at urban schools and 150 vehicles were observed at rural schools. Of the 537 vehicles observed at urban schools, 28.7 percent had children seated in the front seat, whereas 41.3 percent of the 150 vehicles observed at rural schools had front-seated children. Significant urban/rural differences exist in child seat placement, with vehicles in rural areas much more likely to be carrying front-seated children than vehicles in urban areas. Based on a sample of vehicles observed at urban and rural elementary schools in North Dakota, the results of this study indicate that there are significant rural/urban differences in

  6. Apolipoprotein E epsilon-4 polymorphism is associated with younger age at referral to a lipidology clinic and a poorer response to lipid-lowering therapy

    Full Text Available Abstract Background The risk of coronary heart disease (CHD is related to environmental factors and genetic variants. Apolipoprotein E (apoE polymorphisms are heritable determinants of total and low-density lipoprotein cholesterol, with some authors suggesting an association between the ε4 allele and CHD. We investigated the relationship between apoE genotype and age at referral to a specialized lipid clinic by the primary care physician and whether the benefits of treatment with statin differed between genotypes. Methods We assessed individual apoE genotypes and lipid blood profile in a total of 463 patients followed at a specialized lipid clinic due to dyslipidemia, with a 3-year median follow-up time. The primary care physician at the time of the referral had no access to the apoE genotyping results. Carriers of apoE ε4/ε2 genotype were excluded. Results The frequencies of ε2, ε3 and ε4 alleles were 7.8, 78.9 and 13.3%, respectively. There were no significant differences between genders. Although with similar lipid profiles and antidyslipidemic drug usage at baseline, ε4-carriers were referred to the clinic at a younger age (44.2 ± 14.7 years compared with non-ε4 carriers (50.6 ± 13.8 years (p Conclusion Our findings support the concept that there is a reduced response to anti-dyslipidemic treatment in ε4 carriers; this can be a contributing factor for the earlier referral of these patients to our specialized lipid clinic and reinforces the usefulness of apoE genotyping in predicting patients response to lipid lowering therapies.

    A late Pleistocene-early Holocene geological site known as Liverpool East on the southern end of Lake Michigan (in Indiana) was discovered in the early 1980s. Five previously reported radiocarbon dates on wood and peat from the deposit ranged from 9,080 to 11,290 14C yr B.P., but our subsequent radiocarbon dating of wood from in situ spruce stumps at the site has yielded four ages from 10,060 to 10,444 14C yr B.P., which correspond to calibrated calendar ages between about 11,550 and 12,500 Cal yr B.P. These dates place this forest squarely into the Younger Dryas event, and offer an unusual opportunity for exploring high-resolution environmental variability during an abrupt climate change event related to ocean thermohaline circulation. In the last 3 years, we have collected more than 130 pieces of wood from the site, about 65 of which are from stumps. Typical separation of trees was about 2-3 m, suggesting more of an open woodland than dense forest. The tilting of many stumps suggests the effect of wind on trees rooted in a soft peat substrate, and their tops broken at uniform height seem consistent with a subsequent rise in lake level, beach sand deposition, and ice floe event(s) that sheared off the upper trunks. Although these trees tend to be fairly young (typically 50-100 years old) and somewhat complacent, we developed a ring-width chronology to examine interannual variability. We are also measuring stable-oxygen and stable-carbon isotope ratios on α-cellulose in sequences of individual rings for several trees as additional environmental indicators of moisture and temperature. This collective set of tree-ring measurements and their statistics provide the basis for inferring the environment of this site, placed more precisely in time by "wiggle-matching" a sequence of 10-year radiocarbon measurements.

    The Iowa Department of Public Health I-Smile program provides dental screening and care coordination to over 23,000 low-income and Medicaid-enrolled children per year. The purposes of this study were to evaluate I-Smile program effectiveness to ensure that Medicaid-enrolled children obtained dental treatment after having been screened and to determine the factors associated with failure to receive dental care after screening through the I-Smile program. Based on I-Smile program priorities, we limited our sample to children younger than 12 years of age who screened positive for decay and who linked to a paid Medicaid claim for dental treatment (n = 1,816). We conducted bivariate analyses to examine associations between children's characteristics who screened positive for decay and received treatment within 6 months of their initial screening. We also performed multivariate logistic regression to assess the association of sociodemographic characteristics with receipt of treatment among children who screened positive for decay. Eleven percent of children screened positive for decay. Nearly 24 percent of children with decay received treatment based on a Medicaid-paid claim. Being 5 years or older [adjusted odds ratio (aOR): 1.48, confidence interval (CI): 1.17, 1.88] and not having a dental home (aOR: 1.90, CI: 1.41, 2.58) were associated with higher odds of not receiving dental treatment. Children 5 years and older and without a dental home were less likely to obtain dental treatment. Opportunities exist for the I-Smile program to increase the numbers of at-risk children with dental homes and who obtain dental care after screening. © 2014 American Association of Public Health Dentistry.

  10. Age correction in monitoring audiometry: method to update OSHA age-correction tables to include older workers.

    Dobie, Robert A; Wojcik, Nancy C

    2015-07-13

    The US Occupational Safety and Health Administration (OSHA) Noise Standard provides the option for employers to apply age corrections to employee audiograms to consider the contribution of ageing when determining whether a standard threshold shift has occurred. Current OSHA age-correction tables are based on 40-year-old data, with small samples and an upper age limit of 60 years. By comparison, recent data (1999-2006) show that hearing thresholds in the US population have improved. Because hearing thresholds have improved, and because older people are increasingly represented in noisy occupations, the OSHA tables no longer represent the current US workforce. This paper presents 2 options for updating the age-correction tables and extending values to age 75 years using recent population-based hearing survey data from the US National Health and Nutrition Examination Survey (NHANES). Both options provide scientifically derived age-correction values that can be easily adopted by OSHA to expand their regulatory guidance to include older workers. Regression analysis was used to derive new age-correction values using audiometric data from the 1999-2006 US NHANES. Using the NHANES median, better-ear thresholds fit to simple polynomial equations, new age-correction values were generated for both men and women for ages 20-75 years. The new age-correction values are presented as 2 options. The preferred option is to replace the current OSHA tables with the values derived from the NHANES median better-ear thresholds for ages 20-75 years. The alternative option is to retain the current OSHA age-correction values up to age 60 years and use the NHANES-based values for ages 61-75 years. Recent NHANES data offer a simple solution to the need for updated, population-based, age-correction tables for OSHA. The options presented here provide scientifically valid and relevant age-correction values which can be easily adopted by OSHA to expand their regulatory guidance to

    This study described the characteristics and risk factors of neonates who developed retinopathy of prematurity (ROP) and severe treatable ROP in two Egyptian neonatal intensive care units (NICUs). This retrospective cohort study comprised 108 preterm neonates who were screened for ROP after being admitted to the two NICUs run by Cairo University Hospital from June 2014 to May 2015. Patients were examined using digital fundus photography and indirect ophthalmoscopy was performed if ROP was detected. Retinopathy of prematurity occurred in 75 patients. Late-onset sepsis, ventilation and hypercapnia were independently associated with ROP. Patients who developed severe treatable ROP had a younger gestational age (GA) than patients who did not develop ROP or developed mild or moderate ROP (29 weeks, range 27-33 weeks versus 32 weeks, range 28-36 weeks, p = 0.002) and a lower birthweight (1200 g, range 980-1590 g versus 1460 g, range 770-2475 g, p = 0.029). The risk factors associated with severe treatable ROP included the duration of admission, the duration of incubator oxygen, late-onset sepsis, intraventricular haemorrhage, total parenteral nutrition and the duration of caffeine citrate therapy. This study showed that the risks for ROP were wide-ranging and included GA and weight, medical conditions and treatment. ©2017 Foundation Acta Paediatrica. Published by John Wiley & Sons Ltd.

    We examined whether higher effort-reward imbalance (ERI) and lower job control are associated with exit from the labour market. There were 1263 participants aged 50-74 years from the English Longitudinal Study on Ageing with data on working status and work-related psychosocial factors at baseline (wave 2; 2004-2005), and working status at follow-up (wave 5; 2010-2011). Psychosocial factors at work were assessed using a short validated version of ERI and job control. An allostatic load index was formed using 13 biological parameters. Depressive symptoms were measured using the Center for Epidemiologic Studies Depression Scale. Exit from the labour market was defined as not working in the labour market when 61 years old or younger in 2010-2011. Higher ERI OR=1.62 (95% CI 1.01 to 2.61, p=0.048) predicted exit from the labour market independent of age, sex, education, occupational class, allostatic load and depression. Job control OR=0.60 (95% CI 0.42 to 0.85, p=0.004) was associated with exit from the labour market independent of age, sex, education, occupation and depression. The association of higher effort OR=1.32 (95% CI 1.01 to 1.73, p=0.045) with exit from the labour market was independent of age, sex and depression but attenuated to non-significance when additionally controlling for socioeconomic measures. Reward was not related to exit from the labour market. Stressful work conditions can be a risk for exiting the labour market before the age of 61 years. Neither socioeconomic position nor allostatic load and depressive symptoms seem to explain this association. Published by the BMJ Publishing Group Limited.

    One hundred twelve cases of blunt splenic rupture were prospectively entered (October 1987-October 1991) into surgical or nonsurgical management groups using these criteria for the nonsurgical group: hemodynamic stability-age less than 55 years-CT scan appearance of grade I, II, or III injury-absence of concomitant injuries precluding abdominal assessment+absence of other documented abdominal injuries. All ages were included and AAST injury scaling was used. Patients were grouped from the trauma room. The surgical treatment group included 66 patients (49 splenectomies, 17 splenorraphies). These patients were generally older and more severely injured, required more transfused blood, and a longer ICU stay. The nonsurgical group included 46 patients with 33 older than 14 years. There were 3 patients over the age of 55 years inappropriately included in this group, and nonsurgical therapy failed in all three. Statistical analysis (chi 2) showed that more splenic injuries were observed and more spleens were saved with these criteria applied prospectively compared with a previous retrospective series in the same institution. The series had a success rate of 93%, and validates the criteria used for safe, nonsurgical management of the ruptured spleen and adds a new criterion: a maximum age of 55 years

    While healthy aging is associated with physiological changes that can impair control of trunk motion, few studies examine how spinal muscle responses change with increasing age. This study examined whether older (over 65 years) compared to younger (20-45 years) adults had higher overall amplitude and altered temporal recruitment patterns of trunk musculature when performing a functional transfer task. Surface electromyograms from twelve bilateral trunk muscle (24) sites were analyzed using principal component analysis, extracting amplitude and temporal features (PCs) from electromyographic waveforms. Two PCs explained 96% of the waveform variance. Three factor ANOVA models tested main effects (group, muscle and reach) and interactions for PC scores. Significant (pactivity, demonstrated continuous activation levels in specific muscle sites despite changing external moments, and had altered temporal synergies within abdominal and back musculature. In summary both older and younger adults recruit highly organized activation patterns in response to changing external moments. Differences in temporal trunk musculature recruitment patterns suggest that older adults experience different dynamic spinal stiffness and loading compared to younger adults during a functional lifting task.

    Full Text Available Background. Obesity as a civilization disease has been called the "epidemic" in the late twentieth century. It is a risk factor for many diseases, including cardiovascular disease, which is the last time a major cause of death. In Europe and the United States, the number of overweight people exceeds now 50% of the population. The incidence of overweight and obesity continue to rise and this phenomenon is also observed in our country even in case of an early childhood. In Poland, percentage of very young school children (boys and girls who are overweight or obese amounts to about 15%. Obesity is particularly common among children from industrial environments living in highly developed countries. The aim of his study was to assess the level of fat in boys and girls from rural areas aged 7 to 10 from industrial environment. Material and methods. The study was carried out at six rural schools located in the copper mining region in south-west Poland in 2001. For the needs of the study use was made of existing results covering altogether 488 children of early school age – 261 girls and 227 boys. Measurements were taken of height, body mass, waist and hip circumferences. Body fat, body water and lean body mass were measured with Futrex. Respectively the BMI and WHR were calculated from measurements taken earlier. Results and conclusions. The BMI level is within the values of acceptable standard in majority of children. The percentage of children above the standard fluctuates within the limits of typical peers from other regions of the country and is about 15%. In boys obesity increases with age, in girls the values increase also, but they are of lower importance. Most of the examined children present an average level of total body fatness. A very small percentage of them exceeds the level considered as obese.

    The purpose of this study was to compare the incidence rate of invasive pneumococcal disease, the rates of antibiotic resistance and serotype distribution among children ≤5 years old before and after PCVs introduction in Casablanca, Morocco. This study was conducted at the Ibn Rochd University Hospital Centre of Casablanca during two periods encompassing pre-and post-implementation of PCVs, respectively from January 2007 to October 2010 and from January 2011 to December 2014. All the non-duplicate invasive S. pneumoniae isolates recovered during the study periods were included. There were 136 cases of IPD, 91 before and 45 after PCVs introduction. The greatest decrease in incidence rate of IPD occurred in children ≤ 2 years of age declining from 34.6 to 13.5 per 100,000 populations (p<0.0001) before and after vaccination, respectively. The incidence rate of PCV-7, PCV-10 non-PCV-7 and PCV-13 non-PCV-10 serotypes decrease significantly from 18.0 to 4.6, from 5.7 to 1.3 and from 5.7 to 0.8/100,000 population (p<0.001) in the same age, respectively. Shifts in the distribution of IPD serotypes and reductions in the incidence rate of disease suggest an effective reduction of the burden of IPD in children, but continued high quality surveillance is critical to assess the changes in serotype distributions.

    2012-01-01

    Background Despite its high incidence among children under the age of five, little is known about the burden of pediatric gastroenteritis outside the medical setting. The objective of this study was to describe the burden of acute gastroenteritis among children residing in the United Arab Emirates, including those not receiving medical care. Methods A quantitative cross-sectional survey of 500 parents of children under 5 years of age who had suffered from acute gastroenteritis the preceding three months was conducted in the cities of Abu Dhabi and Al Ain. Data collected included respondent characteristics, disease symptoms, medical care sought, and parental expenditures and work loss. Data were analyzed using parametric and non-parametric statistical methods. Results Vomiting and diarrhea episodes lasted on average between 3 and 4 days. Overall, 87% of parents sought medical care for their children; 10% of these cases required hospitalization with an average length of stay of 2.6 days. When medical care was sought, the average parental cost per gastroenteritis episode was US$64, 4.5 times higher than with home care only (US$14). Nearly 60% of this difference was attributable to co-payments and medication use: 69% of children used oral rehydration solution, 68% antiemetics, 65% antibiotics and 64% antidiarrheals. Overall, 38 parents missed work per 100 gastroenteritis episodes for an average of 1.4 days. Conclusions Given its high incidence, pediatric gastroenteritis has an important financial and productivity impact on parents in the United Arab Emirates. To reduce this impact, efforts should be made both to prevent acute gastroenteritis and to optimize its treatment. PMID:22708988

    Background Group A rotaviruses are the most common causative agent of acute gastroenteritis among children less than 5 years of age throughout the world. This sentinel surveillance study was aimed to obtain baseline data on the rotavirus G and P genotypes across Turkey before the introduction of a universal rotavirus vaccination program. Methods Rotavirus antigen-positive samples were collected from 2102 children less than 5 years of age who attended hospitals participating in the Turkish Rotavirus Surveillance Network. Rotavirus antigen was detected in the laboratories of participating hospitals by commercial serological tests such as latex agglutination, immunochromatographic test or enzyme immunoassay. Rotavirus G and P genotypes were determined by reverse transcription polymerase chain reaction (RT-PCR) using consensus primers detecting the VP7 and VP4 genes, followed by semi-nested type-specific multiplex PCR. Results RT-PCR found rotavirus RNA in 1644 (78.2%) of the samples tested. The highest rate of rotavirus positivity (38.7%) was observed among children in the 13 to 24 month age group, followed by children in the age group of 25 to 36 months (28.3%). A total of eight different G types, six different P types, and 42 different G–P combinations were obtained. Four common G types (G1, G2, G3, and G9) and two common P types (P[8] and P[4]) accounted for 95.1% and 98.8% of the strains, respectively. G9P[8] was the most common G/P combination found in 40.5% of the strains followed by G1P[8] (21.6%), G2P[8] (9.3%), G2P[4] (6.5%), G3P[8] (3.5%), and finally, G4P[8] (3.4%). These six common genotypes included 83.7% of the strains tested in this study. The rate of uncommon genotypes was 14%. Conclusion The majority of the strains analyzed belonged to the G1–G4 and G9 genotypes, suggesting high coverage of current rotavirus vaccines. This study also demonstrates a dramatic increase in G9 genotype across the country. PMID:25437502

    To determine the outcome of one-stage combined operative management of congenital dislocation of hips in children aged 18-36 months. The descriptive case series study was conducted at the Department of Orthopaedic Surgery, Jinnah Postgraduate Medical Centre, Karachi, from January 2005 to December 2011. Children aged 18-36 months suffering from congenital dislocation of hips were included. Those with Tonnis stage III and IV were managed with one-stage operative procedure without preliminary traction. The operative procedure included adductor tenotomy, open reduction, capsulorraphy, Salter's osteotomy and a femoral derotation osteotomy. Catteral's 'Test of Stability' was used after open reduction as an indicator for need of pelvic and femoral osteotomies. Follow-up ranged between 1 and 7 years. The patients were evaluated clinically on McKay's criteria and radiologically on Severin's criteria. Klisic's overall rating was used to know mean of the assessments. There were 38 patients with 50 congenital dislocations of hip. There were 26 (68.42%) females and 12 (31.57%) males with a female-to-male ratio of 2:1. Mean age at the time of operation was 24.26 ± 7.6 months. Of the total, 12 (31.57%) patients had bilateral involvement, 11 (28.94%) had right-sided and 15 (39.47%) had left-sided involvement. Right side to Left ratio was 1:1.2. At the time of last follow-up, 25 (50%) hips behaved excellent on McKay's criteria. According to radiographic classification on Severin's criteria, 24 (48%) hips were in excellent class. Avascular necrosis of femoral head was noted in 3 (6%) hips, re-subluxation/re-dislocations were observed in 3 (6%) hips and 1 (2.6%) patient had 1 cm femoral lengthening. One-stage open reduction, capsulorrapyhy, Salter's osteotomy and femoral derotation osteotomy without preliminary traction to re-locate congenital dislocation of hips in late presenting children is a safe and highly effective method. It produces a low rate of complication and need for

    Objective Successful mitral valve replacement in young children is limited by the lack of small prosthetic valves. Supra-annular prosthesis implantation can facilitate mitral valve replacement with a larger prosthesis in children with a small annulus, but little is known about its effect on the outcomes of mitral valve replacement in young children. Methods One hundred eighteen children underwent mitral valve replacement at 5 years of age or younger from 1976–2006. Mitral valve replacement was supra-annular in 37 (32%) patients. Results Survival was 74% ± 4% at 1 year and 56% ± 5% at 10 years but improved over time (10-year survival of 83% ± 7% from 1994–2006). Factors associated with worse survival included earlier mitral valve replacement date, age less than 1 year, complete atrioventricular canal, and additional procedures at mitral valve replacement, but not supra-annular mitral valve replacement. As survival improved during our more recent experience, the risks of supra-annular mitral valve replacement became apparent; survival was worse among patients with a supra-annular prosthesis after 1991. A pacemaker was placed in 18 (15%) patients within 1 month of mitral valve replacement and was less likely in patients who had undergone supra-annular mitral valve replacement. Among early survivors, freedom from redo mitral valve replacement was 72% ± 5% at 5 years and 45% ± 7% at 10 years. Twenty-one patients with a supra-annular prosthesis underwent redo mitral valve replacement. The second prosthesis was annular in 15 of these patients and upsized in all but 1, but 5 required pacemaker placement for heart block. Conclusions Supra-annular mitral valve replacement was associated with worse survival than annular mitral valve replacement in our recent experience. Patients with supra-annular mitral valve replacement were less likely to have operative complete heart block but remained at risk when the prosthesis was subsequently replaced. PMID:18954636

    The objective was to determine the value of radiographs in young adults with non-acute knee symptoms who are scheduled for magnetic resonance imaging (MRI). Nine hundred and sixty-one consecutive patients aged between 16 and 45 years with knee symptoms of at least 4 weeks' duration were prospectively included in three participating hospitals. After applying exclusion criteria, 798 patients remained. Exclusion criteria were previous knee surgery (including arthroscopy) or MRI, history of rheumatoid arthritis, clinical diagnosis of retropatellar chondromalacia, contra-indication for MRI and recent trauma. We identified two groups: group A with no history of trauma (n = 332), and group B with an old (>4 weeks) history of trauma (n = 466). Patients had a standardized history taken, and underwent a physical exam, antero-posterior (AP) and lateral radiographs and MRI. We evaluated the radiographs and MRI for osseous lesions, articular surface lesions, fractures, osteoarthritis, loose bodies, bone marrow edema and incidental findings. Subsequently, patients with osseous abnormalities (Kellgren grade 1 and 2 excluded) on radiographs and a matched control group was evaluated again using MRI without radiographs. Median duration of symptoms was 20 weeks. In group A, radiographs showed 36 osseous abnormalities in 332 patients (10.8%). Only 13 of these, all Kellgren grade 1 osteoarthritis, were not confirmed on MRI. MRI showed 72 (21.7%) additional abnormalities not confirmed on radiographs. In group B, radiographs showed 40 osseous abnormalities (8.6%) in 466 patients. Only 15 of these, all Kellgren grade 1 osteoarthritis, were not confirmed on MRI. MRI showed 194 (41.6%) additional abnormalities not confirmed on radiographs. The second evaluation of MRI without radiographs in 34 patients was identical to the first MRI evaluation. Common lesions were significantly more often diagnosed with MRI than with radiographs. Radiographs should not be obtained routinely when MRI is

    Cervical spondylolysis is a rare condition that results from a pars interarticularis defect. The C-6 level is the most frequently involved site in the cervical spine. Its clinical presentations range from incidental radiographic findings to neck pain and, rarely, neurological deficits. Although 150 patients with subaxial cervical spondylolysis have been reported, a mere 24 adult and pediatric patients with C-2 spondylolysis have been described. The long-term outcomes of very young children with bilateral C-2 spondylolysis are of great interest, yet only a few longitudinal studies exist. The authors retrospectively reviewed 5 cases of bilateral C-2 spondylolysis at Texas Children's Hospital and Riley Children's Hospital; these were combined with 5 other cases in the literature, yielding a total of 10 patients. Data regarding the patients' age, sex, C2-3 angulation and displacement, associated spine anomalies, neurological deficits, treatment, and most recent follow-up were recorded. The patients' ages ranged from 3 to 36 months (mean 12.9 months). There were 6 boys and 4 girls. The C2-3 angulation, displacement, and width of pars defect were measured when available. The mean C2-3 angulation was 9.5° (range 1-34°), the mean C2-3 displacement was 4.78 mm (range 1.1-10.8 mm), and the mean width of the pars defect was 4.16 mm (range 0.9-7 mm). One patient developed myelopathy and spinal cord injury. All 10 of the patients were treated initially with conservative therapy: 3 with close observation alone, 1 with a rigid cervical collar, 4 with a Minerva jacket, 1 with a sternal-occipital-mandibular immobilizer, and 1 with a halo vest. Three patients ultimately underwent surgery for internal fixation due to progressive instability or development of neurological symptoms. All patients were neurologically intact at the last follow-up (mean 44.3 months, range 14-120 months). Based on the literature and the authors' own experience, they conclude that most very young children

    Objectives The US Occupational Safety and Health Administration (OSHA) Noise Standard provides the option for employers to apply age corrections to employee audiograms to consider the contribution of ageing when determining whether a standard threshold shift has occurred. Current OSHA age-correction tables are based on 40-year-old data, with small samples and an upper age limit of 60?years. By comparison, recent data (1999?2006) show that hearing thresholds in the US population have improved....

    This study aims to compare mid-long-term clinical outcomes between patients younger than 60 years of age undergoing bioprosthetic and mechanical aortic valve replacement. From January 2002 to December 2009, patients younger than 60 years of age who received Medtronic Hancock II porcine bioprostheses were selected and compared with those who received mechanical bi-leaflet valves in the aortic position. A stepwise logistic regression propensity score identified a subset of 112 evenly matched patient-pairs. Mid-long-term outcomes of survival, valve-related reoperations, thromboembolic events and bleeding events were assessed. The follow-up was only 95.1% complete. Fourteen measurable variables were statistically similar for the matched cohort. Postoperative in-hospital mortality was 3.6% (bioprosthetic valves) and 2.7% (mechanical valves) (P = 0.700). Survival at 5 and 10 years was 96.3 and 88.7% for patients receiving bioprosthetic valve replacement versus 96.3 and 87.9% for patients receiving mechanical valve replacement (P = 0.860), respectively. At 5 and 10 years after operations, freedom from valve-related reoperation was 97.2 and 94.8% for patients receiving mechanical valve replacement, and 96.3 and 90.2% for patients receiving bioprosthetic valve replacement (P = 0.296), respectively. There was no difference between freedom from thromboembolic events (P = 0.528) and bleeding events (P = 0.128) between the matched groups during the postoperative 10 years. In patients younger than 60 years of age undergoing aortic valve replacement, mid-long-term survival rate was similar for patients receiving bioprosthetic versus mechanical valve replacement. Bioprosthetic valves were associated with a trend for a lower risk of anticoagulation treatment and did not have significantly greater likelihood of a reoperation. These findings suggest that a bioprosthetic valve may be a reasonable choice for AVR in patients younger than 60 years of age. © The Author 2015. Published by

    Because low birth weight is associated with adverse cardiovascular risk and death in adults, lipoprotein heterogeneity at birth was studied. A prominent, large high-density lipoprotein (HDL) subclass enriched in apolipoprotein C-I (apoC-I) was found in 19 percent of infants, who had significantly lower birth weights and younger gestational ages and distinctly different lipoprotein profiles than infants with undetectable, possible or probable amounts of apoC-I-enriched HDL. An elevated amount of an apoC-I-enriched HDL identifies a new group of low birth weight infants.

    The interaction between age and culture can have various implications for cognition as age represents the effect of biological processes whereas culture represents the effect of sustaining experiences. Nevertheless, their interaction has rarely been examined. Thus, based on the fact that Asians are more intuitive in reasoning than Americans, we examined how this cultural difference might interact with age. Young and old participants from the US and Singapore performed a categorization task (living vs. non-living). To measure their reliance on intuition, we manipulated the typicality of targets (animate vs. inanimate). We showed that (1) RTs for inanimate organisms were slower than RTs for animate organisms (atypicality cost), (2) the cost was particularly large for older adults and (3) an age × culture interaction was observed such that cultural differences in the cost (Singaporeans > Americans) was found only among older participants. Further, we demonstrated that the age effect was associated with cognitive function and the culture effect among older adults was associated with cultural values. Finally, a moderated mediation analysis suggests that cognitive function and cultural values interact with each other in order to jointly influence one's cognition.

    The aim of this systematic review is to summarise quantitative studies in occupational settings observing the association between Information communication technology (ICT) and stress, and burnout, considering age as an effect modifier. A systematic review using PRISMA guidelines was conducted through the following bibliographic databases: PubMed, Web of Science, Psycinfo, and the Cochrane Library. Inclusion criteria were occupational settings and content relevant to our research question. Risk of bias was assessed using the Newcastle-Ottawa scale. Two interventional, 4 cohorts, and 29 cross-sectional studies were found. ICT use in occupational settings was associated with stress seen in cross-sectional studies, but not in interventional studies. There was a concordant association with ICT and burnout in different study designs. Overall, there were no linear trends between age and technostress. We suggest that the observed associations were mostly present in the middle-aged working population and that these associations need to be supported in further studies.

    Full Text Available Aim: The purpose of this study was to determine the incidence of anterior cruciate ligament (ACL lesions and osteochondral lesions according to type and localization of the meniscal tear and age, gender in patients who have been arthroscopicaly treated, besides, to make the coexisting lesions more predictable in these patients. Methods: We retrospectively investigated 352 patients under 50 years of age who underwent surgery for a meniscal tear between 2008 and 2012. We scanned the surgical operation notes, preoperative questionnaires and the magnetic resonance imaging findings. We recorded patients who had ACL lesions, such as elongation, partial rupture and total rupture. Osteochondral lesions were classified according to the Outerbridge classification from grade 1 to grade 4. Results: Chondral lesions were present in 77.4% of patients with degenerative meniscal tears and in 63% of patients with radial meniscal tears. One the other hand, osteochondral lesions were observed in only 33.9% of patients with other types of meniscal tears. 46.6% of ACL lesions accompanied by meniscal tears with longitudinal pattern, such as longitudinal tears, bucket handle tears and root tears. For the other types of meniscal tears, this percentage was 20.7. When we excluded degenerative type meniscal tears, the mean age of the patients with radial tears was 40.86±9.03 years and the mean age of the patients with other types of tear was 35.44±9.44 years. The difference was statistically significant. Conclusion: We found close relationship between osteoarthritic chondral lesions and radial tears in the root of the posterior horn of the medial meniscus. On the other side, longitudinal tears were related with ACL lesions. (The Me­di­cal Bul­le­tin of Ha­se­ki 2014; 52: 177-80

    Background Body image is a complex issue with the potential to impact many aspects of cancer survivorship, particularly for the younger breast cancer survivor. Objective The purpose of this review is to synthesize the current state of the science for body image in younger women with breast cancer. Intervention/Methods Combinations of the terms “body image,” “sexuality intervention,” “women,” “younger women,” and “breast cancer” were searched in the PubMed, PsycInfo, CINAHL, Web of Knowledge and Science Direct databases through January 2014. Inclusion criteria for this review were: 1) original research; 2) published in English from the year 2000 forward; 3) measuring body image as an outcome variable; and 4) results included reporting of age-related outcomes. Results Thirty-six articles met the inclusion criteria. The majority of studies were cross-sectional, with extensive variation in body image assessment tools. Age and treatment type had a significant impact on body image, and poorer body image was related to physical and psychological distress, sex and intimacy, and the partnered relationship among younger women. Only one intervention study found a significant improvement in body image post-intervention. Conclusions Findings suggest body image is a complex post-treatment concern for breast cancer survivors, particularly younger women. The findings of this review are limited by the high level of variation in the methods for assessing body image. Implications for Practice Further research of interventions to address body image concerns following treatment for breast cancer is warranted. Improvement of body image may improve the quality of life of younger breast cancer survivors. PMID:25881807

    Full Text Available The author introduces unemployment of youths in Slovenia and throws light on the reasons for this phenomenon. Later on she explains the importance of obtaining a profession and a job. She points out the psycho-social consequences of unemployment with young people and the characteristics of the target group of unemployed younger adults. She quotes the data concerning the young unemployed involved in criminal offences in 1997 and 1998 and tries to find the reasons why educating this target group is not only necessary but indispensable. There is a short presentation ofthe project »5000 Youths« in 1998 and participating of the unemployed in it. The author enumerates the schools which implemented the project and their experiences in educating adults. According to data, the majority of schools do have these experiences. Within the project there was also a modular program for education of teachers. The results of a questionnaire, represented in the article, show the meaning of such education for teachers and their experiences in working with the unemployed.

    Purpose: Mastectomy is often recommended for women ≤40 years of age with breast cancer, as young women were under-represented in the landmark trials comparing breast conservation therapy (BCT) to mastectomy. We hypothesized that, in the modern treatment era, BCT and mastectomy result in equivalent local control rates in young women. Methods and Materials: Breast cancer cases arising between 1975 and 2013 in women ≤40 years old were collected from the tumor registries of 2 large healthcare systems in Utah. Kaplan-Meier estimates and Cox proportional hazards models were used to analyze freedom from locoregional recurrence (FFLR), overall survival (OS), and relapse-free survival (RFS). Results: This analysis identified 853 BCT candidates. A comparison of BCT to mastectomy after 2000 showed FFLR, RFS, and OS were all similar. Rate for FFLR at 10 years was 94.9% versus 92.1% for BCT and mastectomy, respectively (P=.57). For women whose cancer was diagnosed after 2000, who received BCT, FFLR and RFS rates were improved compared to those whose cancer was diagnosed prior to 2000 (P<.05), whereas OS (P=.46) rates were similar. Among those who underwent mastectomy, FFLR, OS, and RFS were significantly improved (P<.05) with diagnosis after 2000. Conclusions: FFLR rates for young women, ≤40 years of age, have significantly improved for BCT and mastectomy over time. If patients were treated after 2000, BCT appears to be safe and equivalent to mastectomy at 10 years in terms of FFLR, OS, and RFS.

    Analysing the relationship between gender and memory, and examining the effects of age on the overall memory-related functioning, are the ongoing goals of psychological research. The present study examined gender and age group differences in episodic memory with respect to the type of task. In addition, these subgroup differences were also analysed in visual working memory. A sample of 366 women and 330 men, aged between 16 and 69 years of age, participated in the current study. Results indicate that women outperformed men on auditory memory tasks, whereas male adolescents and older male adults showed higher level performances on visual episodic and visual working memory measures. However, the size of gender-linked effects varied somewhat across age groups. Furthermore, results partly support a declining performance on episodic memory and visual working memory measures with increasing age. Although age-related losses in episodic memory could not be explained by a decreasing verbal and visuospatial ability with age, women's advantage in auditory episodic memory could be explained by their advantage in verbal ability. Men's higher level visual episodic memory performance was found to result from their advantage in visuospatial ability. Finally, possible methodological, biological, and cognitive explanations for the current findings are discussed.

    Information regarding acute otitis media (AOM) aetiology is important for developing effective vaccines. Here, bacterial aetiology and antimicrobial susceptibility of AOM were determined in young Saudi children. Children aged 3-60months with a new episode of AOM, who had not received antibiotics or had received antibiotics for 48-72h but remained symptomatic, were enrolled in this prospective, observational, epidemiological study in Riyadh. Middle ear fluid (MEF) samples were collected by tympanocentesis or from spontaneous otorrhea, and tested for the presence of Streptococcus pneumoniae, Haemophilus influenzae, Streptococcus pyogenes and Moraxella catarrhalis. Antimicrobial susceptibility of the identified pathogens was assessed using E-tests. Between June 2009 and May 2011, 66 children were enrolled. S. pneumoniae was detected in 6 episodes and non-typeable H. influenzae (NTHi) in 8 episodes. Moreover, Staphylococcus aureus, which is an uncommon cause of AOM, was detected in 17 episodes. Pneumococcal serotypes were 7F (n=2), 23F (n=2), 19F (n=1) and 15F (n=1). Susceptibility to cefotaxime was observed in all pneumococcal and H. influenzae isolates, to cefuroxime in 4/6 pneumococcal and 8/8 H. influenzae isolates, and to penicillin in 5/6 pneumococcal isolates. S. pneumoniae and NTHi were major bacterial contributors for AOM in Saudi children. Copyright © 2014. Published by Elsevier Ltd.

    The timing of most recurrences after neonatal urinary tract infection is during the first year of life, with peak incidence 2-6 months after the initial infection. Information on the microbiologic characteristics of recurrent urinary tract infection episodes in relation to the microbiology of the initial episodes is limited. To analyze the epidemiologic/microbiological characteristics of 1st and recurrent urinary tract infection in infants urinary tract infection admitted during 2005-2009 and followed till the age of 1 year. 151 neonates were enrolled (2.7% of all 5617 febrile infants urinary tract infection occurring during the first 2 months of life was 151/73,480 (0.2%) live births during 2005-2009 in southern Israel (2.1 cases/1000 live births). One pathogen was isolated in 133 (88.1%); Escherichia coli, Klebsiella spp., Enterococcus spp., Morganella morganii, Proteus spp., and Enterobacter spp. represented the most common pathogens (57.9%, 12.2%, 7.9%, 6.7%, 6.1%, and 5%, respectively). Trimethoprim/sulfamethoxazole, ampicillin, and cefuroxime-axetil were the most commonly recommended prophylactic antibiotics (45%, 13.2%, and 8%, respectively). Twenty-three recurrent urinary tract infection episodes were recorded in 20 (13.2%) patients; 6/23 (26%) were diagnosed within one month following 1st episode. E. coli was the most frequent recurrent urinary tract infection pathogen (12/23, 52.2%). No differences were recorded in E. coli distribution between first urinary tract infection vs. recurrent urinary tract infection. Seventeen (74%) recurrent urinary tract infection episodes were caused by pathogens different (phenotypically) from those isolated in 1st episode. Recurrent urinary tract infection occurred in 25.0%, 8.3%, and 0 patients recommended trimethoprim/sulfamethoxazole, cefuroxime-axetil, or amoxicillin prophylaxis, respectively.

    Background: Thyroid cancer is unique for having age as a staging variable. Recently, the commonly used age cut-point of 45 years has been questioned. Objective: This study assessed alternate staging systems on the outcome of overall survival, and compared these with current National Thyroid Cancer Treatment Cooperative Study (NTCTCS) staging systems for papillary and follicular thyroid cancer. Methods: A total of 4721 patients with differentiated thyroid cancer were assessed. Five potential alternate staging systems were generated at age cut-points in five-year increments from 35 to 70 years, and tested for model discrimination (Harrell's C-statistic) and calibration (R2). The best five models for papillary and follicular cancer were further tested with bootstrap resampling and significance testing for discrimination. Results: The best five alternate papillary cancer systems had age cut-points of 45–50 years, with the highest scoring model using 50 years. No significant difference in C-statistic was found between the best alternate and current NTCTCS systems (p = 0.200). The best five alternate follicular cancer systems had age cut-points of 50–55 years, with the highest scoring model using 50 years. All five best alternate staging systems performed better compared with the current system (p = 0.003–0.035). There was no significant difference in discrimination between the best alternate system (cut-point age 50 years) and the best system of cut-point age 45 years (p = 0.197). Conclusions: No alternate papillary cancer systems assessed were significantly better than the current system. New alternate staging systems for follicular cancer appear to be better than the current NTCTCS system, although they require external validation. PMID:26203804

    The goals of this study were to determine the learning impact of an assignment that consisted of interviewing and analyzing older people's life stories, and to explore how the assignment was evaluated by students. Participants in the study were 122 first-year social education students enrolled in an adult development and aging course. They evaluated the assignment using an eight-adjective questionnaire and were asked about the benefits of the task. Their answers to the questionnaire were then reviewed using content analysis. The results indicated that marks on the life story assignment predicted marks on an exam about basic course concepts. Students considered that the assignment was interesting, useful, and integrated into the course, although most of them also thought that it was very time-consuming. They identified benefits related to the explicit goals of the course (improvement in the learning of developmental concepts, the acquisition of research-related skills, and the deactivation of aging stereotypes) and personal, growth-related benefits. The authors discuss the difficulties posed by the assignment and its usefulness as a complement to more traditional, lecture-based teaching methods in adult development and aging courses.

  2. Enduring effects of severe developmental adversity, including nutritional deprivation, on cortisol metabolism in aging Holocaust survivors.

    In animal models, early life exposure to major environmental challenges such as malnutrition and stress results in persisting cardiometabolic, neuroendocrine and affective effects. While such effects have been associated with pathogenesis, the widespread occurrence of 'developmental programming' suggests it has adaptive function. Glucocorticoids may mediate 'programming' and their metabolism is known to be affected by early life events in rodents. To examine these relationships in humans, cortisol metabolism and cardiometabolic disease manifestations were examined in Holocaust survivors in relation to age at exposure and affective dysfunction, notably lifetime posttraumatic stress disorder (PTSD). Fifty-one Holocaust survivors and 22 controls without Axis I disorder collected 24-h urine samples and were evaluated for psychiatric disorders and cardiometabolic diagnoses. Corticosteroids and their metabolites were assayed by gas chromatography-mass spectroscopy (GC-MS); cortisol was also measured by radioimmunoassay (RIA). Holocaust survivors showed reduced cortisol by RIA, and decreased levels of 5alpha-tetrahydrocortisol (5alpha-THF) and total glucocorticoid production by GC-MS. The latter was associated with lower cortisol metabolism by 5alpha-reductase and 11beta-hydroxysteroid dehydrogenase (11beta-HSD) type-2. The greatest decrements were associated with earliest age of Holocaust exposure and less severe PTSD symptomatology. Cardiometabolic manifestations were associated with decreased 11beta-HSD-2 activity. In controls, 5alpha-reductase was positively associated with trauma-related symptoms (i.e., to traumatic exposures unrelated to the Holocaust). Extreme malnutrition and related stress during development is associated with long-lived alterations in specific pathways of glucocorticoid metabolism. These effects may be adaptive and link with lower risks of cardiometabolic and stress-related disorders in later life.

Analysis was adjusted for whether women had been age-eligible for HPV vaccination or not. For the LBC-screened group, the overall referral and detected CIN2+ rates were 27/995 (2.7% [95% CI 1.8%-3.9%]) and 1/995 (0.1% [95% CI 0.0%-0.6%]), respectively; for HPV+LBC triage, these were 75/1,992 (3.8% [95% CI 3.0%-4.7%]) and 20/1,992 (1.0% [95% CI 0.6%-1.5%]); and for HPV+DS triage, these were 79/2,008 (3.9% [95% CI 3.1%-4.9%]) and 24/2,008 (1.2% [95% CI 0.8%-1.6%]) (p = 0.09 for difference in referral rate in LBC versus all HPV-screened women; p = 0.003 for difference in CIN2+ detection rate in LBC versus all HPV-screened women, with p = 0.62 between HPV screening groups). Limitations include that the study population involved a relatively low risk group in a previously well-screened and treated population, that individual women's vaccination status was unknown, and that long-term follow-up data on disease detection in screen-negative women are not yet available. In this study, primary HPV screening was associated with significantly increased detection of high-grade precancerous cervical lesions compared to cytology, in a population where high vaccine uptake was reported in women aged 33 years or younger who were offered vaccination. It had been predicted that increased disease detection might be associated with a transient increase in colposcopy referral rates in the first round of HPV screening, possibly dampened by HPV vaccine effect; in this study, although the point estimates for referral rates in women in each HPV-screened group were 41%-44% higher than in cytology-screened women, the difference in referral rate between cytology- and HPV-screened women was not significant. These findings provide initial support for the implementation of primary HPV

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

    Younger or older age has a significant impact on the outcome of patients with head and neck cancer. However, the data regarding outcomes based on age are conflicting. The aim of this article is to determine the impact of age on the outcome of laryngeal cancer. A retrospective study was performed including all patients with squamous cell carcinoma of the larynx for over a 9-year period. The patients were divided into 3 groups based on age. The younger age group included patients 40 years of age and younger, the older group included patients over 80 years of age, and the remaining patients served as the control group. Descriptive statistics were used to summarize study data. Nonparametric quantitative and qualitative analyses were performed using the Mann-Whitney U test and Fisher's exact test, respectively. Survival analysis was performed using the generalized Wilcoxon test. The Cox proportional hazards model was used for multivariate analysis. Of the 209 patients with laryngeal carcinoma presenting to our institution over a 9-year period, 20 (10%) were or =80 years of age. No differences in TNM stage at presentation, treatment, or treatment-associated complications were observed based on age. However, younger patients were less likely to report tobacco (50%; P likely to have human immunodeficiency virus infection (50%; Pcause-specific survival significantly poorer for both younger and older patients (P = .002). The presentation and outcome of laryngeal cancer is influenced by the age at presentation. The differences may be related exact reason for the observed survival differences needs to be determined.

    Recent geologic study shows that all hominins and nearly all other published mammalian fossils from Paleontological Collection Area 123, Koobi Fora, Kenya, derive from levels between the KBS Tuff (1.87+/-0.02 Ma) and the Lower Ileret Tuff (1.53+/-0.01 Ma). More specifically, the fossils derive from 53 m of section below the Lower Ileret Tuff, an interval in which beds vary markedly laterally, especially those units containing molluscs and algal stromatolites. The upper Burgi Member (approximately 2.00-1.87 Ma) crops out only in the southwestern part of Area 123. Adjacent Area 110 contains larger exposures of the member, and there the KBS Tuff is preserved as an airfall ash in lacustrine deposits and also as a fluvially redeposited ash. We observed no mammalian fossils in situ in this member in Area 123, but surface specimens have been documented in some monographic treatments. Fossil hominins from Area 123 were attributed to strata above the KBS Tuff in the 1970s, but later they were assigned to strata below the KBS Tuff (now called the upper Burgi Member). This study definitively places the Area 123 hominins in the KBS Member. Most of these hominins are between 1.60 and 1.65 myr in age, but the youngest may date to only 1.53 Ma, and the oldest, to 1.75 Ma. All are 0.15-0.30 myr younger than previously estimated. The new age estimates, in conjunction with published taxonomic attributions of fossils, suggest that at least two species of Homo coexisted in the region along with A. boisei until at least 1.65 Ma. Comparison of crania KNM-ER 1813 and KNM-ER 1470, which were believed to be of comparable age, is at the focus of the debate over whether Homo habilis sensu lato is in fact composed of two species: Homo habilis and Homo rudolfensis. These two crania are separated in time by approximately 0.25 myr, and therefore, arguments for their conspecificity no longer need to confront the issue of unusually high contemporaneous variation within a single species.

    The authors studied 66 women referred for forensic evaluation and classified them into two age groups: 48 women 17-39 years old composed a young adult group and 18 women 40-54 years old composed a midlife group. The midlife group included a significantly larger number of first-time offenders with a higher frequency of medical as well as psychiatric disorders. None of the women in the midlife group was diagnosed as having antisocial personality disorder, but this was the most common diagnosis among the younger women. The authors note the implications of these findings for treatment of older female offenders, especially those in midlife.

  12. On the origins of ageism among older and younger adults.

    Ageism is apparent in many social structures and contexts and in diverse forms over the life cycle. This review discusses the development and consequences of ageism toward elderly people by others of any age, according to the Terror Management Theory (TMT) and the Social Identity Theory (SIT). A systematic search of the literature was carried out on the social and psychological origins of ageism in younger and older adults. Studies on the reasons for ageism among older adults point to attitudes that older adults have toward their own age group, while studies on ageism in young adults explain it as an unconscious defensive strategy which younger adults use against death anxiety. In other words, TMT can serve as a suitable framework for ageism in younger adults, and SIT appears to explain ageism in older adults. A dissociation of the linkage between death and old age in younger adults can be achieved by changing the concepts of death and old age. For older adults, it is recommended to improve self-worth by encouraging social contacts in which older adults contribute to younger adults, weaken the effects of age stereotypes in TV programs, and prepare middle-aged adults for living healthy lives as older adults. However, these conclusions should be regarded with caution, because several key areas (age related cues, activated cognitive processes, impact of death awareness on ageism) need to be investigated in order to validate this understanding of the origins of ageism among younger and older adults.

  13. The effects of sleep on episodic memory in older and younger adults.

    Evidence on sleep-dependent benefits for episodic memory remains elusive. Furthermore we know little about age-related changes on the effects of sleep on episodic memory. The study we report is the first to compare the effects of sleep on episodic memories in younger and older adults. Memories of stories and personal events were assessed following a retention interval that included sleep and following an equal duration of wakefulness. Both older and younger adults have superior memory following sleep compared to following wakefulness for both types of material. Amount of forgetting of personal events was less during wakefulness in older adults than in younger adults, possibly due to spontaneous rehearsal. Amount of time spent sleeping correlated highly with sleep benefit in older adults, suggesting that quantity of total sleep, and/or time spent in some stages of sleep, are important contributors to age-related differences in memory consolidation or protection from interference during sleep.

    Field investigations at the Public Shooting Grounds (a wildlife-management area on the northeastern shore of Great Salt Lake) and radiocarbon dating show that the Great Salt Lake rose to the Gilbert shoreline sometime between 12.9 and 11.2 cal ka. We interpret a ripple-laminated sand unit exposed at the Public Shooting Grounds, and dated to this time interval, as the nearshore sediments of Great Salt Lake deposited during the formation of the Gilbert shoreline. The ripple-laminated sand is overlain by channel-fill deposits that overlap in age (11.9-11.2 cal ka) with the sand, and by wetland deposits (11.1 to 10.5 cal ka). Consistent accelerator mass spectrometry radiocarbon ages were obtained from samples of plant fragments, including those of emergent aquatic plants, but mollusk shells from spring and marsh deposits yielded anomalously old ages, probably because of a variable radiocarbon reservoir effect. The Bonneville basin was effectively wet during at least part of the Younger Dryas global-cooling interval, however, conflicting results from some Great Basin locations and proxy records indicate that the regional effects of Younger Dryas cooling are still not well understood. ?? 2005 Elsevier B.V.

    Abstract Objective: To determine the prevalence of otitis media with effusion in children younger than 1 year and its association with the season of the year, artificial feeding, environmental and perinatal factors. Methods: Retrospective study of 184 randomly included medical records from a total of 982 healthy infants evaluated for hearing screening tests. Diagnosis of otitis media with effusion was based on otoscopy (amber-gold color, fluid level, handle of malleus position), type B tympanometric curves and absence of otoacoustic emissions. Incomplete medical records or those describing acute otitis media, upper respiratory tract infections on the assessment day or in the last 3 months, neuropathies and craniofacial anomalies were excluded. Data such as gestational age, birth weight, Apgar score, type of feeding and day care attendance were compared between children with and without otitis media with effusion through likelihood tests and multivariate analysis. Results: 25.3% of 184 infants had otitis media with bilateral effusion; 9.2% had unilateral. In infants with otitis media, the following were observed: chronological age of 9.6±1.7 months; gestational age >38 weeks in 43.4% and birth weight >2500g in 48.4%. Otitis media with effusion was associated with winter/fall, artificial feeding, Apgar score otitis media with effusion. Conclusions: Otitis media with effusion was found in about one third of children younger than 1 year and was mainly associated with artificial feeding. PMID:26559603

    polypharmacy is an important risk factor for falls, but recent studies suggest only when including medications associated with increasing the risk of falls. a prospective, population-based cohort study. 6,666 adults aged ≥50 years from The Irish Longitudinal study on Ageing. participants reported regular medication use at baseline. Any subsequent falls, any injurious falls and the number of falls were reported 2 years later. The association between polypharmacy (>4 medications) or fall risk-increasing medications and subsequent falls or injurious falls was assessed using modified Poisson regression. The association with the number of falls was assessed using negative binomial regression. during follow-up, 231 falls per 1,000 person-years were reported. Polypharmacy including antidepressants was associated with a greater risk of any fall (adjusted relative risk (aRR) 1.28, 95% CI 1.06-1.54), of injurious falls (aRR 1.51, 95% CI 1.10-2.07) and a greater number of falls (adjusted incident rate ratio (aIRR) 1.60, 95% CI 1.19-2.15), but antidepressant use without polypharmacy and polypharmacy without antidepressants were not. The use of benzodiazepines was associated with injurious falls when coupled with polypharmacy (aRR 1.40, 95% CI 1.04-1.87), but was associated with a greater number of falls (aIRR 1.32, 95% CI 1.05-1.65), independent of polypharmacy. Other medications assessed, including antihypertensives, diuretics and antipsychotics, were not associated with outcomes. in middle-aged and older adults, polypharmacy, including antidepressant or benzodiazepine use, was associated with injurious falls and a greater number of falls. © The Author 2014.

    This study was undertaken to assess the safety and efficacy of minimally invasive percutaneous nephrolithotomy (mini-PCNL) using ureteroscope and pneumatic intracorporeal lithotripsy in preschool age children with kidney calculi. We studied 27 renal units in 20 patients of preschool age (≤ 6 years) who underwent mini-PCNL at our institute. The mean age was 42.6 months (range 14-68 months). The average stone burden was 1.85 cm (range 0.9-2.8 cm). Eight patients aged 14 to 58 months had been exposed to melamine-tainted powdered formula. The mini-PCNL was performed with an X-ray-guided peripheral puncture. Minimal tract dilatation was undertaken to fit a 14-16 Fr peel-away sheath. Ureteroscope and pneumatic intracorporeal lithotripsy were used to fragment the stones. Complete clearance was achieved in 23 renal units (85.2 %) with mini-PCNL monotherapy. This has increased to 92.6 % after adjunctive ESWL. The average fall in hemoglobin was 1.28 g/dL. None of the patients required blood transfusion. The median length of hospital stay was 8.2 days. Patients were followed up every 6 months for 2 years. There has been only one recurrence of stone and no long-term complications. Mini-PCNL is a effective treatment for pediatric kidney stones refractory to extracorporeal shock wave lithotripsy, including stones induced by melamine-contaminated milk powder. The "mini-PCNL" technique, which uses ureteroscope and pneumatic intracorporeal lithotripsy, is a safe and feasible modality for treating renal calculi in preschool age children.

    This paper describes the methodological developments of the sexual health items included in the Health Behaviour in School-aged Children (HBSC) study since their mandatory inclusion in the study in 2002. The current methodological, ethical and pedagogical challenges in measuring young people's sexual health behaviours are discussed along with the issues associated with the sexual health items introduced to the HBSC study in 2002. The development and piloting of new cross-national items for use in the 2013/14 HBSC data collection are presented and discussed. An international pilot study was undertaken to determine the impact of these proposed changes. Questionnaires and classroom discussion groups were conducted in five pilot countries in 2012/2013 (France, Hungary, Ireland, Portugal and Romania) with a total of 612 school-aged children (age M = 15.55 years, SD = 0.95). The majority of participants in each country provided positive feedback about the appropriateness of the questions. Some small cross-national differences were found in the self-reported quantitative data relating to the appropriateness of the questions (χ 2  = 22.831, df = 9, p = .007, V = .117). Qualitative feedback suggests that for the vast majority of students the phrasing and age-targeting of the questions were considered appropriate. With the exception of a small number of respondents who commented on the clarity and/or personal nature of the content, no specific issues with the questions were identified. These findings provide guidance on the answerability (including the extent of missing and inconsistent data), understandability, acceptability (including in different cultures) and relevance of questions to potential participants. The findings from the pilot study suggest that in general, the questions are understandable, acceptable, and of a high priority to the target population, and that the simplification has significantly reduced the proportion of missing data

    Full Text Available Human resource management has an important impact on age diversity in companies. Age diversity in the workplace is growing and older employees are staying longer in the workforce, therefore it is important that employers can create a positive environment for age diverse employees. This paper introduces the difference in stereotypes in the workplace between older and younger employees in Slovenian companies. The main goal of this paper is to present the importance of age diversity and their age difference in stereotypes in the workplace. The paper is based on a research including a survey between two age groups of employees. We classified younger employees in the group of under 50 years of age and older employees in the group of above 50 years of age. For data analysis we used the non-parametric Mann-Whitney U test to verify the differences in stereotypes in the workplace between two groups. Results show that there are significant differences in all of the variables describing stereotypes in the workplace between younger and older employees in Slovenian companies.

    To explore the differences in various tinnitus-related features and psychological aspects between the younger and older adult patients with tinnitus. We retrospectively reviewed the clinical data of the adult patients who visited our tinnitus clinic in 2013 and completed full tinnitus assessment including audiometry, tinnitus matching, standardized tinnitus questionnaires, and psychometric questionnaires. The younger group included patients aged 20-45 years (n=64), and the older group, those older than 65 years (n=76). Clinical features, hearing levels, matched tinnitus pitches and loudness, self-report tinnitus severity scores, Beck depression inventory scores, and stress scores were compared between the groups. Tinnitus duration was longer in the older group (p=0.002). Mean PTAs were 16dB HL in the younger, and 38dB HL in the older groups (ptinnitus loudness was greater in the older group (64dB HL vs. 36dB HL, ptinnitus, depression, and stress scores did not differ between the groups. The older patients seemed to be more receptive to tinnitus. The majority of older tinnitus patients had concomitant hearing loss, and thus hearing rehabilitation should be considered preferentially for tinnitus management in this age group. Subjective tinnitus severity, depressive symptoms, and the stress levels were similar between the younger and older tinnitus patients. Therefore, treatment could be planned based upon the comprehensive understanding of the tinnitus characteristics and psychological aspects in each patient irrespective of age.

    Full Text Available The Visinin-like 1 (VSNL1 gene encodes Visinin-like protein 1, a peripheral biomarker for Alzheimer disease (AD. Little is known, however, about normal VSNL1 expression in brain and the biologic networks in which it participates. Frontal cortex gray matter from 209 subjects without neurodegenerative or psychiatric illness, ranging in age from 16–91, were processed on Affymetrix GeneChip 1.1 ST and Human SNP Array 6.0. VSNL1 expression was unaffected by age and sex, and not significantly associated with SNPs in cis or trans. VSNL1 was significantly co-expressed with genes in pathways for Calcium Signaling, AD, Long Term Potentiation, Long Term Depression, and Trafficking of AMPA Receptors. The association with AD was driven, in part, by correlation with amyloid precursor protein (APP expression. These findings provide an unbiased link between VSNL1 and molecular mechanisms of AD, including pathways implicated in synaptic pathology in AD. Whether APP may drive increased VSNL1 expression, VSNL1 drives increased APP expression, or both are downstream of common pathogenic regulators will need to be evaluated in model systems.

    Full Text Available Aim of the study: We compared stone size, localization, complaint at the time of applying, comorbidity, treatment and complications between older (60 years of age and older and younger patients with urolithiasis (59 years of age and younger. Materials and Methods: We retrospectively reviewed the records of 950 consecutive patients who presented to our clinic and underwent surgery for urolithiasis from January 2007 to March 2012. The patients were divided into two groups: patients ≥ 60 years an patients < 60 years. Results: There were 174 men and 61 women in elderly group, 528 men and 187 women in younger group. Ureteral stones were found more often in the younger group compared to elderly patients (p < 0.05. Conversely, bladder stone was more frequent in the elderly group. In the elderly group comorbidities are more frequent (diabetes mellitus, hypertension, ischemic heart disease, congestive heart disease, osteoarthritis and chronic obstructive lung. Patients ≥ 60 years significantly had larger kidney and bladder stones compared the younger, but ureteral stone sizes were not statistically different between the two groups. Older patients had a higher postoperative complication rate than younger patients (16% versus 3%, p < 0.05 although postoperative complications (e.g. urinary retention, cardiac dysrythmia, fever, constipation were not serious and resolved with medical treatment. The average length of stay in hospital was longer in the elderly group, but the difference was not statistically significant. Conclusions: Elderly patients with urolithiasis usually have larger and more complex stone disease, more comorbidities and atypical presentation.

    User performance, perceived usability, and preference for five smartphone text input methods were compared with younger and older novice adults. Smartphones are used for a variety of functions other than phone calls, including text messaging, e-mail, and web browsing. Research comparing performance with methods of text input on smartphones reveals a high degree of variability in reported measures, procedures, and results. This study reports on a direct comparison of five of the most common input methods among a population of younger and older adults, who had no experience with any of the methods. Fifty adults (25 younger, 18-35 years; 25 older, 60-84 years) completed a text entry task using five text input methods (physical Qwerty, onscreen Qwerty, tracing, handwriting, and voice). Entry and error rates, perceived usability, and preference were recorded. Both age groups input text equally fast using voice input, but older adults were slower than younger adults using all other methods. Both age groups had low error rates when using physical Qwerty and voice, but older adults committed more errors with the other three methods. Both younger and older adults preferred voice and physical Qwerty input to the remaining methods. Handwriting consistently performed the worst and was rated lowest by both groups. Voice and physical Qwerty input methods proved to be the most effective for both younger and older adults, and handwriting input was the least effective overall. These findings have implications to the design of future smartphone text input methods and devices, particularly for older adults. © 2015, Human Factors and Ergonomics Society.

    Caregiver burden in dementia is an important issue, but few studies have examined the mental health of younger and older family caregivers by comparing them with age- and gender-matched community residents. We aimed to compare the mental health of dementia caregivers with that of community residents and to clarify factors related to mental health problems in younger and older caregivers. We studied 104 dementia caregivers; 46 were younger (caregivers and community residents by age. Behavioural and psychological symptoms of dementia, activities of daily living (ADL), and instrumental ADL were assessed among patients with dementia using the Neuropsychiatric Inventory, Physical Self-Maintenance Scale, and Lawton Instrumental ADL Scale, respectively. According to SF-8 results, both younger and older caregivers had significantly worse mental QOL than community residents (younger caregivers: 46.3 vs community residents: 49.7, P = 0.017; older caregivers: 48.2 vs community residents: 51.1, P = 0.024) but were not more depressive. Sleep problems were significantly more frequent in younger caregivers (39.1%) than in community residents (17.0%) (P = 0.017). Multiple regression analysis revealed that caregivers' deteriorated mental QOL was associated with patients' behavioural and psychological symptoms of dementia in younger caregivers and with dementia patients' instrumental ADL and female gender in older caregivers. Dementia caregivers had a lower mental QOL than community residents. To maintain caregivers' mental QOL, it is necessary to provide younger caregivers with skills or professional interventions for dealing with behavioural and psychological symptoms of dementia, and older caregivers must be offered adequate care support. © 2016 The Authors.

    To determine the prevalence of otitis media with effusion in children younger than 1 year and its association with the season of the year, artificial feeding, environmental and perinatal factors. Retrospective study of 184 randomly included medical records from a total of 982 healthy infants evaluated for hearing screening tests. Diagnosis of otitis media with effusion was based on otoscopy (amber-gold color, fluid level, handle of malleus position), type B tympanometric curves and absence of otoacoustic emissions. Incomplete medical records or those describing acute otitis media, upper respiratory tract infections on the assessment day or in the last 3 months, neuropathies and craniofacial anomalies were excluded. Data such as gestational age, birth weight, Apgar score, type of feeding and day care attendance were compared between children with and without otitis media with effusion through likelihood tests and multivariate analysis. 25.3% of 184 infants had otitis media with bilateral effusion; 9.2% had unilateral. In infants with otitis media, the following were observed: chronological age of 9.6±1.7 months; gestational age >38 weeks in 43.4% and birth weight >2,500g in 48.4%. Otitis media with effusion was associated with winter/fall, artificial feeding, Apgar score otitis media with effusion. Otitis media with effusion was found in about one third of children younger than 1 year and was mainly associated with artificial feeding. Copyright © 2015 Sociedade de Pediatria de São Paulo.

    A community-based, cluster-randomized, placebo-controlled trial of daily zinc and/or iron+folic acid supplementation was conducted in rural southern Nepal to examine motor milestone attainment among 3264 children 1-36 mo of age between 2001 and 2006. Treatment groups included placebo, zinc (10 mg), iron+folic acid (12.5 mg iron + 50 microg folic acid), and zinc+iron+folic acid (10 mg zinc + 12.5 mg iron + 50 microg folic acid). Infants received half of these doses. The iron arms were stopped November 2003 by recommendation of the Data Safety and Monitoring Board; zinc and placebo continued until January 2006. A total of 2457 children had not walked at the time of entry into the trial and 1775 were followed through 36 mo. Mean age at first walking unassisted did not differ among groups and was 444 +/- 81 d (mean +/- SD) in the placebo group, 444 +/- 81 d in the zinc group, 464 +/- 85 d in the iron+folic acid group, and 446 +/- 87 d in the iron+folic acid+zinc group. Results were similar after adjustment for age at enrollment, asset ownership, maternal literacy, and prior child deaths in the household and in children who consumed at least 60 tablets. Compared with placebo, iron+folic acid was associated with an adjusted mean delay of 28.0 d (95% CI: 11.3, 44.7) in time to walking among infants and the delay was more pronounced with mid-upper arm circumference (MUAC) < 9.5 cm [60.6 d, (95% CI: 28.5, 92.6)]. Risks and benefits of universal iron+folic acid supplementation of infants beyond improved hematologic status deserve further consideration.

    based on a proper understanding of the values and value functions of younger citizens. Such information must thus be an integral part of the knowledge base to be used when plans and processes are being developed for dismantling and decommissioning of nuclear power plants and other older nuclear facilities. In the present project, empirical data have been collected and compiled in a survey of the values of younger citizens with regard to decommissioning and dismantling of older nuclear facilities. The survey constitutes a stratified sample from three towns in Poland. They are Lublin, Olsztyn and Gdansk. A total of 780 students in the age group 14-19 years participated in the Survey. The results are compared to those from a similar study in the County of Kalmar in Sweden in the year 2006. The results include some major lesson learned. These may be summarised as follows: - Younger citizens tend to base their values regarding decommissioning on safety, and environmental aspects. Aspects like future economic growth and technological processes are less influential on the values. - Younger citizens tend to express a lack of information and debate as a basis of their value functions. Likewise, they tend to express interest in the topic and are open to become more included in the processes. - Younger citizens have suggestions on how more information can be made accessible to the general public. - Younger citizens need to be better included in the stakeholder process. This can be achieved by allowances from the Swedish Nuclear Waste Fund to support groups of younger citizens to follow the Swedish process of research, development and demonstration of a concept for the management of spent nuclear fuel. Less than fully accessible information campaigns about nuclear power and associated nuclear waste may result in differences in confidence levels between different groups of stakeholders. By finding out more about the values of different stakeholders it will be possible for the

    In 2011, a workplace project was established to provide a small group of people who had younger onset dementia with the opportunity to return to the workplace. The project sought to explore the feasibility and safety of engaging these younger people in workplace activities if an appropriate framework of support was provided. Opportunities to engage in meaningful activities are quite limited for younger people with dementia because services are targeted at an older client population. A qualitative exploratory approach was used for the project evaluation. Participants were people who were 65 years or younger and had a diagnosis of dementia. They attended a large metropolitan hardware store one day per week and worked beside a store employee for a four hour work shift. Evaluation of the project included observation of participant's engagement in the workplace, adverse events and a qualitative analysis that used participant-nominated good project outcomes. Nine people with a mean age of 58·8 years participated in the project. Six of these participants have been engaged at the workplace for more than two years. All participants were able to gain the skills needed to complete their respective work duties. Participants initially assisted with simple work tasks, but over time, they were able to expand their range of duties to include more complex activities such as customer sales. Participants achieved their nominated good outcomes of improved well-being, engaging in worthwhile activities, contributing to society and socialisation. The evaluation has shown that this workplace programme is a viable model of engagement for younger people with dementia. This evaluation offers a practical demonstration that it is feasible and safe to provide opportunities for younger people with dementia to engage in meaningful activities in the community if appropriate support is provided. © 2015 John Wiley & Sons Ltd.

    To delineate the role of the oncology patient navigator, drawing from the experiences and descriptions of younger women with breast cancer. Interpretive, descriptive, qualitative research design. Participants' homes, researcher's home, and via telephone, all in Winnipeg, Manitoba, Canada. 12 women aged 50 years or younger who were diagnosed with breast cancer within the last three years. Face-to-face semistructured interviews explored patient experiences with the cancer care system, including problems encountered, unmet needs, and opinions about the functions of the patient navigator role. The audio-recorded interviews were transcribed and data were broken down and inductively coded into four categories. Constant comparative techniques also were used during analysis. The role of the oncology patient navigator included two facets: "Processual facets," with the subthemes assigned to me at diagnosis, managing the connection, mapping the process, practical support, and quarterbacking my entire journey; and "Personal qualities: The essentials," with the subthemes empathetic care tenor, knowing the cancer system, and understanding the medical side of breast cancer. Despite the tremendous effort directed toward enhancing care for younger women undergoing treatment for breast cancer, gaps continue to exist. Younger women with breast cancer require a care approach providing ongoing dialogue, teaching, and emotional support from the point of diagnosis through treatment, including transitions of care within the oncology setting and back to their primary care practitioner. Oncology nurse navigators are well positioned to provide patients with anticipatory guidance from diagnosis to the end of treatment.

    Growing evidence implicates a decline in white matter integrity in the age-related decline in motor control. Functional neuroimaging studies show significant associations between functional connectivity in the cortical motor network, including the supplementary motor area (SMA), and motor performance. Dual-coil transcranial magnetic stimulation studies show facilitatory connections between SMA and the primary motor cortex (M1) in younger adults. Here, we investigated whether SMA-M1 facilitation is affected by age and whether the strength of SMA-M1 facilitation is associated with bilateral motor control. Dual-coil transcranial magnetic stimulation was used to measure SMA-M1 connectivity in younger (N = 20) and older adults (N = 18), and bilateral motor control was measured with the assembly subtest of the Purdue Pegboard and clinical measures of dynamic balance. SMA-M1 facilitation was seen in younger but not older adults, and a significant positive association was found between SMA-M1 facilitation and bimanual performance. These results show that SMA-M1 facilitation is reduced in older adults compared to younger adults and provide evidence of the functional importance of SMA-M1 facilitation.

    Video laryngoscopy facilitates tracheal intubation during manual in-line stabilization in adults, but it is not clear whether these findings translate to children. We compared trainee intubation times obtained using the GlideScope Cobalt® and Storz DCI® video laryngoscopes versus direct laryngoscopy in young children with immobilized cervical spines. Ninety-three children younger than 2 years underwent laryngoscopy with manual in-line stabilization using direct laryngoscopy, GlideScope Cobalt® video laryngoscopy, or Storz DCI® video laryngoscopy. Laryngoscopists were anesthesiology trainees in postgraduate training year of 3 or more. Total time to successful intubation (TTSI), best glottic view, and maximum degrees of neck deviation were recorded. An intubation time difference longer than 10 seconds was defined as clinically significant. Data are reported as median; 95% confidence interval. The TTSI was similar among groups although Storz times were longer (median, 33.3 seconds; 95% confidence interval, 26.2-43.3 seconds) when compared to direct laryngoscopy (median, 23.3 seconds; 95% confidence interval, 20.7-26.5 seconds; P = 0.02). Obtaining a grade 1 Cormack-Lehane glottic view was less likely with direct laryngoscopy (P = 0.002). Maximum degrees of neck deviation were: Storz (median, 2.0; 95% confidence interval, 1.2-2.8), GlideScope (median, 2.0; 95% confidence interval, 1.4-2.6), and direct laryngoscopy (median, 1.9; 95% confidence interval, 1.2-2.1; P = 0.48). Trainees were able to safely perform tracheal intubation in children younger than 2 years using any of the studied laryngoscopes, although Storz use resulted in a longer TTSI when compared to direct laryngoscopy. Video laryngoscopy may enhance best Cormack-Lehane glottic view during manual in-line cervical spine immobilization, but additional technical skills are needed to successfully complete tracheal intubation.

    To address the question of whether or not elderly problem drinkers experience any treatment contact discrimination or recovery rate disadvantages, the programme utilization and recovery rate experiences of a representative sample of older and younger persons arrested for drinking and driving (OWI) in Iowa were compared. Subjects were interviewed by phone or mail shortly after their OWI arrest and then again approximately 12 months later. Younger persons (18-54 years old) were compared with elderly persons (55 and over and 65 and over). The elderly subjects were also dichotomized as early onset (at least one problem drinking indicator occurred prior to age 55) or late onset (all problem drinking indicators occurred at age 55 or later). The elderly were as likely as, or more likely than, their younger counterparts to make a treatment contact, to remain in treatment and to recover.

    How tandem autologous-allogeneic stem cell transplantation should be integrated in the treatment of multiple myeloma remains controversial. We examined the long-term outcome of patients with multiple myeloma managed with tandem autologous-allogeneic stem cell transplantation and present a prognostic factor analysis based on the experience of the Société Française de Greffe de Moelle et de Thérapie Cellulaire (SFGM-TC). This French, retrospective, registry-based study included 146 patients who had undergone tandem autologous-allogeneic transplantation for multiple myeloma at 20 SFGM-TC centers between 1998 and 2010. The patients included in the study had fully completed the two steps of a planned tandem autologous-allogeneic transplantation. No treatment had to be administered between the autologous and allogeneic parts of the tandem procedure. Seventy-seven patients (53%) underwent tandem autologous-allogeneic transplantation as part of upfront treatment, i.e. after a single line of treatment not including autologous transplantation. The median follow-up from the allogeneic transplant was 47.5 months (range, 1.2-132 months). At 4 years, the overall survival and event-free survival rates were 48% (95% CI 39-57 %) and 27% (95% CI 19-36), respectively. Eighteen patients (12%) experienced grade III-IV acute graft-versus-host disease and 43 patients (30%) had chronic graft-versus-host disease. The transplant-related mortality rate at 1 year was 15% (95% CI 10-22). Patients receiving tandem transplantation as upfront treatment had significantly improved event-free survival (36% versus 11%; P=0.005) and overall survival (56% versus 34%; P=0.02). Donor's age ≤ 50 years was associated with improved event-free survival (35% versus 16%; P=0.005) and overall survival (54% versus 41%; P=0.02). In the multivariable analysis, upfront tandem transplantation, donor's age ≤ 50 years and full chimerism were independent prognostic factors for better outcome. We confirmed the

    Researchers have suggested that older adults express less negative emotions. Yet, emotional expression patterns in older and younger breast cancer survivors, have barely been examined. This study aimed to explore types and intensity of negative and positive emotional expression related to the breast cancer experience by younger and older Arab breast cancer survivors. Participants were 20 younger (aged 32-50) and 20 older (aged 51-75) Muslim and Christian Arab breast cancer survivors (stages I-III), currently free of disease. Data were gathered through in-depth semi-structured interviews. Mixed methods analyses were conducted, including: (1) frequency analysis of participants' emotional expressions; (2) content analysis of emotional expressions, categorized according to negative and positive emotions. Three emotional expression modalities were revealed: (1) Succinct versus comprehensive accounts; (2) expression of emotions versus avoidance of emotions; (3) patterns of expression of positive emotions and a sense of personal growth. Younger women provided more detailed accounts about their illness experiences than older women. Older women's accounts were succinct, action-focused, and included more emotion-avoiding expressions than younger women. Understanding the relationships between emotional expression, emotional experience, and cancer survivors' quality of life, specifically of those from traditional communities, is necessary for developing effective psycho-social interventions.

    The Younger Dryas (YD) impact hypothesis is a recent theory that suggests that a cometary or meteoritic body or bodies hit and/or exploded over North America 12,900 years ago, causing the YD climate episode, extinction of Pleistocene megafauna, demise of the Clovis archeological culture, and a range of other effects. Since gaining widespread attention in 2007, substantial research has focused on testing the 12 main signatures presented as evidence of a catastrophic extraterrestrial event 12,900 years ago. Here we present a review of the impact hypothesis, including its evolution and current variants, and of efforts to test and corroborate the hypothesis. The physical evidence interpreted as signatures of an impact event can be separated into two groups. The first group consists of evidence that has been largely rejected by the scientific community and is no longer in widespread discussion, including: particle tracks in archeological chert; magnetic nodules in Pleistocene bones; impact origin of the Carolina Bays; and elevated concentrations of radioactivity, iridium, and fullerenes enriched in 3He. The second group consists of evidence that has been active in recent research and discussions: carbon spheres and elongates, magnetic grains and magnetic spherules, byproducts of catastrophic wildfire, and nanodiamonds. Over time, however, these signatures have also seen contrary evidence rather than support. Recent studies have shown that carbon spheres and elongates do not represent extraterrestrial carbon nor impact-induced megafires, but are indistinguishable from fungal sclerotia and arthropod fecal material that are a small but common component of many terrestrial deposits. Magnetic grains and spherules are heterogeneously distributed in sediments, but reported measurements of unique peaks in concentrations at the YD onset have yet to be reproduced. The magnetic grains are certainly just iron-rich detrital grains, whereas reported YD magnetic spherules are

    Full Text Available Objectives: This study aimed to compare cardiovascular disease (CVD risk factors, lifestyle habits and pharmacological treatment in two groups of elder adults with 20 years difference in their mean age. Methods: This study comprised 590 women including two groups with mean age of 42.4±5.5 vs. 66.5±4.0 years, and 486 men of two groups with mean age of 44.1±5.6 vs. 63.9±7.0 years. Data on physical examination, fasting blood analyses, 7-day dietary re-cords, physical activity, smoking and actual medication use were recorded. Results: Compared with younger individuals, seniors had a more adverse risk factor profile in terms of abdominal obesity, over-weight, hyperglycemia, hypertension, dyslipoproteinemia without differences in HDL-C. But this is not reflected by lifestyle behav-ior. Less than 2% of the elderly and 17% of the younger adults were current smoker. Furthermore, the pattern of physical activ-ity was different in terms of more continuous sports in seniors contrasting with extremes between no sports and more than twice a week in the younger group. Seniors consumed significantly less carbohydrates including more monosaccharide and less polysaccharides, more alcohol and water. The intake of fat and protein was higher in elder women than in all other groups. One third of seniors took antihypertensive medications and 12% used lipid modifying drugs. Conclusions: Different levels of prevention against CVDs and their risk factors shall be considered for various age groups of population. The findings of this study emphasize on the necessity of preventive measures against smoking and physical inactivity in younger adults and dietary habits in seniors.

  7. The effectiveness of breast cancer screening by mammography in younger women.

    1993-02-25

    We reviewed the evidence relating to breast screening using mammography in younger women, primarily those aged 40 to 49. The best evidence comes from the 6 published randomized trials. We performed a metaanalysis, assessing the breast cancer death rates for each year of follow-up in each trial, and producing summary estimates of the cumulative and year-specific mortality rates. At 7 to 10 years, death rates in screened and unscreened groups are similar. This lack of benefit contrasts with the average 30% mortality reduction in women over age 50 in the same trials. This evidence provides no basis for the promotion of mammographic screening in women under age 50 in the general population. If mammography is to be offered to asymptomatic women of that age who request it, appropriate information including the fact that there has been no demonstrated ultimate benefit should be given. The difference in effectiveness may relate both to the greater difficulty in distinguishing normal from abnormal tissue, and to greater growth speed and different biological characteristics of tumors, in younger women. We also reviewed recommendations from major groups: in general multidisciplinary bodies which rely on structured evaluations do not recommend screening in younger women, while many other specialty associations and cancer societies do. Overall, the trials of screening of younger women show a small increase in mortality in those screened, and possible explanations of this are discussed. [corrected] Remaining questions concern the precise age at which effectiveness changes, the situation in high-risk women, and the impact of improved or more frequent screening.

    People who have experienced illness due to significant disease, multimorbidity and/or advanced age are high utilizers of the health care system. Yet this population has had little formal opportunity to participate in guiding the health care research agenda, and few mechanisms exist for researchers to engage this population in an efficient way. We describe the process of developing a standing patient and family advisory panel to incorporate this population's voice into research in the USA. The panel was created at the University of Colorado. Preliminary panel development consisted of a needs assessment, information gathering and participant recruitment. We collected feedback from researchers who consulted with the panel and from panel members in order to better understand the experience from the patient and family member perspective. The patient and family research advisory panel consists of eight advisors who have experience with significant disease, multimorbidity and/or advanced age, two physicians and a program manager. The panel meets every other month for 2 hours with the main purpose of advising diverse researchers on health care studies. People with significant disease, multimorbidity and/or advanced age represent a growing demographic in the USA, and their engagement in research is essential as the model of health care delivery moves from volume to value. © The Author 2017.

    The purpose of this study was to examine differences between older and younger adults who received integrated treatment for co-occurring substance use and mental disorders, including differences on demographic and baseline characteristics (e.g., substance use, readiness for change, mental health symptoms, and severity of problems associated with substance use), as well as predictors of retention in treatment. This study included 1400 adults who received integrated substance abuse and mental health treatment services at one of two private residential facilities offering residential and outpatient services. Initial analyses consisted of basic descriptive and bivariate analyses to examine differences between older (≥ 50 years old) and younger (co-occurring substance use and mental health disorders by documenting that age-based differences exist in general and in the factors that are associated with the length of stay in residential treatment.

    Resveratrol (RVTL) is a flavonoid found in red wine and has been publicized heavily as an anti-aging compound. Indeed, basic research confirms that although there is much hype in the promotion of RVTL, flavonoids such as RVTL have a wide range of biological effects. We here investigated the effects of RVTL treatment on hippocampal plasticity and memory performance in female Balb/C mice, a strain with low baseline levels of adult neurogenesis. Two weeks of treatment with RVTL (40 mg/kg) induced the production of new neurons in vivo by increasing cell survival and possibly precursor cell proliferation. In addition, RVTL decreased the number of apoptotic cells. The number of doublecortin (DCX)-expressing intermediate cells was increased. RVTL stimulated neuronal differentiation in vitro without effects on proliferation. In the dentate gyrus, RVTL promoted the formation and maturation of spines on granule cell dendrites. RVTL also improved performance in the step down passive avoidance test. The RVTL-treated mice showed increase in the levels of two key signaling proteins, phospho-Akt and phospho-PKC, suggesting the involvement of these signaling pathways. Our results support the vision that flavonoids such as resveratrol deserve further examination as plasticity-inducing compounds in the context of successful cognitive aging. PMID:26695764

    Low back pain (LBP) in older adults is poorly understood because the vast majority of the LBP research has focused on the working aged population. The aim of this study was to compare older adults consulting with chronic LBP to middle aged and young adults consulting with chronic LBP, in terms of their baseline characteristics, and pain and disability outcomes over 1 year. Data were systematically collected as part of routine care in a secondary care spine clinic. At initial presentation patients answered a self-report questionnaire and underwent a physical examination. Patients older than 65 were classified as older adults and compared to middle aged (45-65 years old) and younger adults (17-44 years old) for 10 baseline characteristics. Pain intensity and disability were collected at 6 and 12 month follow-ups and compared between age groups. A total of 14,479 participants were included in the study. Of these 3087 (21%) patients were older adults, 6071 (42%) were middle aged and 5321 (37%) were young adults. At presentation older adults were statistically different to the middle aged and younger adults for most characteristics measured (e.g. less intense back pain, more leg pain and more depression); however, the differences were small. The change in pain and disability over 12 months did not differ between age groups. This study found small baseline differences in older people with chronic LBP compared to middle aged and younger adults. There were no associations between age groups and the clinical course. Small baseline differences exist in older people with chronic low back pain compared to middle aged and younger adults referred to secondary care for chronic low back pain. Older adults present with slightly less intense low back pain but slightly more intense leg pain. Changes in pain intensity and disability over a 12 month period were similar across all age groups. © 2017 European Pain Federation - EFIC®.

    It was examined whether the single embryo transfer policy makes the treatment period longer for couples to achieve their first live birth by assisted reproductive technology. This study retrospectively analyzed women who started assisted reproductive technology at younger than 40 years of age in the authors' organization. The treatment periods for couples to achieve the first live birth by assisted reproductive technology, between the women who started assisted reproductive technology from 2004 to 2009 (the double embryo transfer period group, n=250), in which the double embryo transfer was predominant, and the women who started assisted reproductive technology from 2010 to 2015 (the single embryo transfer period group, n=298), in which the single embryo transfer was predominant, were compared. The age at the start of assisted reproductive technology, pregnancy rate per embryo transfer, and rate of women who achieved a live birth by assisted reproductive technology per number of women who tried assisted reproductive technology were all significantly higher in the single embryo transfer period group. Among the women who achieved a live birth by assisted reproductive technology, the incidence of multiple births and severe ovarian hyperstimulation syndrome, the treatment period, and medical care costs needed to achieve the first live birth were all significantly lower in the single embryo transfer period group. In the single embryo transfer period group, those women who were younger than 40 years of age achieved their first live birth by assisted reproductive technology more safely, quickly, and reasonably.

    To evaluate for the first time the effects of a combination of sage, rosemary and melissa (Salvia officinalis L., Rosmarinus officinalis L. and Melissa officinalis L.; SRM), traditional European medicines, on verbal recall in normal healthy subjects. To devise a suitable study design for assessing the clinical efficacy of traditional herbal medicines for memory and brain function. Forty-four normal healthy subjects (mean age 61 ± 9.26y SD; m/f 6/38) participated in this study. A double-blind, randomised, placebo-controlled pilot study was performed with subjects randomised into an active and placebo group. The study consisted of a single 2-week term ethanol extract of SRM that was chemically-characterised using high resolution LC-UV-MS/MS analysis. Immediate and delayed word recall were used to assess memory after taking SRM or placebo (ethanol extract of Myrrhis odorata (L.) Scop.). In addition analysis was performed with subjects divided into younger and older subgroups (≤ 62 years mean age n = 26: SRM n = 10, Placebo n = 16; ≥ 63 years n = 19: SRM n = 13, Placebo n = 6). Overall there were no significant differences between treatment and placebo change from baseline for immediate or delayed word recall. However subgroup analysis showed significant improvements to delayed word recall in the under 63 year age group (p memory in healthy subjects under 63 years of age. Short- and long- term supplementation with SRM extract merits more robust investigation as an adjunctive treatment for patients with Alzheimer's disease and in the general ageing population. The study design proved a simple cost effective trial protocol to test the efficacy of herbal medicines on verbal episodic memory, with future studies including broader cognitive assessment.

    Animal research and human neuroimaging studies indicate that stress increases dopamine levels in brain regions involved in reward processing, and stress also appears to increase the attractiveness of addictive drugs. The current study tested the hypothesis that stress increases reward salience, leading to more effective learning about positive than negative outcomes in a probabilistic selection task. Changes to dopamine pathways with age raise the question of whether stress effects on incentive-based learning differ by age. Thus, the present study also examined whether effects of stress on reinforcement learning differed for younger (age 18-34) and older participants (age 65-85). Cold pressor stress was administered to half of the participants in each age group, and salivary cortisol levels were used to confirm biophysiological response to cold stress. After the manipulation, participants completed a probabilistic learning task involving positive and negative feedback. In both younger and older adults, stress enhanced learning about cues that predicted positive outcomes. In addition, during the initial learning phase, stress diminished sensitivity to recent feedback across age groups. These results indicate that stress affects reinforcement learning in both younger and older adults and suggests that stress exerts different effects on specific components of reinforcement learning depending on their neural underpinnings.

    We investigated how the anticipation of remote monetary reward modulates intentional episodic memory formation in younger and older adults. On the basis of prior findings of preserved reward-cognition interactions in aging, we predicted that reward anticipation would be associated with enhanced memory in both younger and older adults. On the basis of previous demonstrations of a time-dependent effect of reward anticipation on memory, we expected the memory enhancement to increase with study-test delay. In Experiment 1, younger and older participants encoded a series of picture stimuli associated with high- or low-reward values. At test (24-hr postencoding), recognition hits resulted in either high or low monetary rewards, whereas false alarms were penalized to discourage guessing. Experiment 2 was similar to Experiment 1, but the study-test delay was manipulated within subjects (immediate vs 24hr). In Experiment 1, younger and older adults showed enhanced recognition for high-reward pictures compared with low-reward pictures. Experiment 2 replicated this finding and additionally showed that the effect did not extend to immediate recognition. The current findings provide support for a time-dependent mechanism of reward-based memory enhancement. They also suggest that aging leaves intact the positive influence of reward anticipation on intentional long-term memory formation. © The Author 2013.

    Purpose: To detect a difference in outcome (disease-specific survival, local tumor progression, late toxicity, quality of life) after curative radiotherapy for localized prostate cancer in elderly as compared to younger patients. Patients and methods: In a retrospective analysis 59 elderly patients (>74 years old) were matched 1:2 with younger patients from the data base according to tumor stage, grading, pre-treatment PSA values and year of radiotherapy. Surviving patients were contacted to fill in a validated questionnaire for quality of life measurement (EORTC QLQ-C30). Median follow-up for elderly and younger patients was 5.2 and 4.5 years, respectively. Results: Overall survival at 5 years was 66% for the elderly and 80% for younger patients. Intercurrent deaths were observed more frequently in the elderly population. There was no age-specific difference in disease-specific survival (78% vs 82%), late toxicity or quality of life. Clinically meaningful local tumor progression was observed in 15% and 14%, respectively, corresponding to data from the literature following hormonal ablation. Conclusions: There is no obvious difference in outcome including disease-specific survival, late toxicity and quality of life in elderly patients, compared to a matched younger population. A clinically meaningful local tumor progression following radiotherapy or hormonal ablation only is rare. Local radiotherapy or, alternatively, hormonal ablation is recommended to preserve local progression-free survival in elderly patients except for very early stage of disease (i.e. T1 G1-2 M0).

    Our state Breast and Cervical Cancer Program (BCCP) has previously reported a paucity of data supporting breast screening for asymptomatic women younger than 40 (cancer detection rate of .25% per screening-year). In partnership with the local Affiliate of the Susan G. Komen for the Cure Foundation, we began a targeted "screening" program to evaluate women younger than 40 referred for symptoms or other concerns. Retrospective data review of program results, including demographics, symptoms, evaluations performed, and outcomes. A total of 176 women, ages 16 to 39 years, were referred to the BCCP/Komen program. Of the women with documented presenting symptoms, the most common was breast lump (81%). Evaluation triggered 75 surgical referrals and 69 biopsies, yielding 16 cancers (a biopsy positive rate of 23% and overall cancer detection rate from the program of 9%). For women younger than age 40, targeted breast cancer screening is a more efficient utilization of screening resources, with a higher cancer detection rate than asymptomatic screening.

    Many older adults lack the capacity to stand up again after a fall. Therefore, to analyse falls it is relevant to understand recovery patterns, including successful and failed attempts to get up from the floor in general. This study analysed different kinematic features of standing up from the floor. We used inertial sensors to describe the kinematics of lie-to-stand transfer patterns of younger and healthy older adults. Fourteen younger (20-50 years of age, 50% men) and 10 healthy older community dwellers (≥60 years; 50% men) conducted four lie-to-stand transfers from different initial lying postures. The analysed temporal, kinematic, and elliptic fitting complexity measures of transfer performance were significantly different between younger and older subjects (i.e., transfer duration, angular velocity (RMS), maximum vertical acceleration, maximum vertical velocity, smoothness, fluency, ellipse width, angle between ellipses). These results show the feasibility and potential of analysing kinematic features to describe the lie-to-stand transfer performance, to help design interventions and detection approaches to prevent long lies after falls. It is possible to describe age-related differences in lie-to-stand transfer performance using inertial sensors. The kinematic analysis remains to be tested on patterns after real-world falls.

    To compare cases of poisoning according to age to detect differences in frequency of visits to the emergency department, patient characteristics, case management, and immediate outcome in terms of related mortality. Descriptive study of a retrospective series of patients who visited a university hospital emergency department for treatment of poisoning between 2009 and 2014. We collected patient characteristics and data related to the event, case management, and poisoning-related death. Patients were grouped according to age (cut-off 65 y). Of a total of 3847 poisoning episodes, 341 (8.9%) were in patients aged 65 years or older. The percentage of women among these older patients (61.3%) was greater than among younger patients (36.3%; P<.001). Poisoning was accidental in older patients more often than younger ones (64.4% vs 9.5%, respectively; P<.001), occurred more often in the home (82.1% vs 37%, P<.001), and more often required active treatment (73.3% vs 57.4%; P<.001) and admission to hospital (21.4% vs 7.3%, P<.001). The related mortality rate was also higher in the older patients (2.1% vs 0.1% in younger patients, P<.001). The percentage of poisonings in patients aged 65 years or older is not negligible. Poisoning in patients of advanced age tends to be accidental and take place in the home. Older patients more often require active treatment and hospital admission; poisoning-related death is more common in older patients than younger ones.

    The demonstrated health benefits of active commuting (AC) and low participation rates among older adults indicate a need to examine the socioecological correlates of AC by age category. An online survey of employed U.S. adults examined AC participation and individual, employment-related, community, and environmental variables. Participants were dichotomized by age (younger: 18-49 yr; n = 638, 64% and older: ≥ 50 yr; n = 359, 36%). Logistic-regression analyses examined differences in AC correlates by age. Older adults were less likely to be active commuters (13.4%) than younger adults (27.9%; p adults, analyses yielded a Nagelkerke R2 = .76, with perceived behavioral control, behavioral beliefs, household cars, and walking distance as predictors. Analyses for younger adults resulted in a Nagelkerke R2 = .79, with perceived behavioral control, coworker normative beliefs, parking problems at work, greater employer and community support for AC, and bad weather as predictors. Findings suggest age should be considered when examining and targeting AC behaviors.

    We have uncovered a thin layer of magnetic grains and microspherules, carbon spherules, and glass-like carbon at nine sites across North America, a site in Belgium, and throughout the rims of 16 Carolina Bays. It is consistent with the ejecta layer from an impact event and has been dated to 12.9 ka BP coinciding with the onset of Younger Dryas (YD) cooling and widespread megafaunal extinctions in North America. At many locations the impact layer is directly below a black mat marking the sudden disappearance of the megafauna and Clovis people. The distribution pattern of the Younger Dryas boundary (YDB) ejecta layer is consistent with an impact near the Great Lakes that deposited terrestrial-like ejecta near the impact site and unusual, titanium-rich projectile-like ejecta further away. High water content associated with the ejecta, up to 28 at. percent hydrogen (H), suggests the impact occurred over the Laurentide Ice Sheet. YDB microspherules and magnetic grains are highly enriched in TiO{sub 2}. Magnetic grains from several sites are enriched in iridium (Ir), up to 117 ppb. The TiO{sub 2}/FeO, K/Th, TiO{sub 2}/Zr, Al{sub 2}O{sub 3}/FeO+MgO, CaO/Al{sub 2}O{sub 3}, REE/ chondrite, FeO/MnO ratios and SiO{sub 2}, Na{sub 2}O, K{sub 2}O, Cr{sub 2}O{sub 3}, Ni, Co, U, Th and other trace element abundances are inconsistent with all terrestrial and extraterrestrial (ET) sources except for KREEP, a lunar igneous rock rich in potassium (K), rare-earth elements (REE), phosphorus (P), and other incompatible elements including U and Th. Normal Fe, Ti, and {sup 238}U/{sup 235}U isotopic abundances were found in the magnetic grains, but {sup 234}U was enriched over equilibrium values by 50 percent in Murray Springs and by 130 percent in Belgium. 40K abundance is enriched by up to 100 percent in YDB sediments and Clovis chert artifacts. Highly vesicular carbon spherules containing nanodiamonds, glass-like carbon, charcoal and soot found in large quantities in the YDB layer are

    Older patients frequently receive angiotensin II receptor blocker/diuretic combinations to control blood pressure (BP), although there have been relatively few trials specifically examining this patient population. A pooled analysis was performed of data from 7 randomized trials of telmisartan/hydrochlorothiazide combinations or telmisartan monotherapy in older (65 years and older) and younger (younger than 65 years) patients to better understand the response of older patients to a telmisartan/hydrochlorothiazide combination. Telmisartan doses were 40 mg and 80 mg (T40 and T80). Hydrochlorothiazide doses were 12.5 mg and 25 mg (H12.5 and H25). A total of 3654 patients were included and the mean treatment duration was approximately 8 weeks. BP reductions with telmisartan/hydrochlorothiazide combinations were broadly similar in older and younger patients. In older patients, mean BP reductions from baseline were -30.1/-19.0 mm Hg with the T80/H25 combination and -21.7/-13.0 mm Hg with T80 monotherapy. Tolerability was similar regardless of age, and the incidence of adverse events in both older and younger patients was similar to placebo. The telmisartan/hydrochlorothiazide combination, particularly high-dose T80/H25, is effective and well tolerated in patients 65 years and older as well as in younger patients. © 2013 Wiley Periodicals, Inc.

    Full Text Available OBJECTIVE: To assess the in-hospital results and clinical follow-up of young patients (< 50 years with multivessel coronary artery disease undergoing stent implantation in native coronary arteries and to compare their results with those of patients with single-vessel coronary artery disease. METHODS: We retrospectively studied 462 patients undergoing coronary stent implantation. Patients were divided into 2 groups: group I (G-I - 388 (84% patients with single-vessel coronary artery disease; and group II (G-II - 74 (16% patients with multivessel coronary artery disease. RESULTS: The mean age of the patients was 45±4.9 years, and the clinical findings at presentation and demographic data were similar in both groups. The rate of clinical success was 95% in G-I and 95.8% in G-II (P=0.96, with no difference in regard to in-hospital evolution between the groups. Death, acute myocardial infarction, and the need for myocardial revascularization during clinical follow-up occurred in 10.1% and 11.2% (P=0.92 in G-I and G-II, respectively. By the end of 24 months, the actuarial analysis showed an event-free survival of 84.6 % in G-I and 81.1% in G-II (P=0.57. CONCLUSION: Percutaneous treatment with coronary stent implantation in young patients with multivessel disease may be safe with a high rate of clinical success, a low incidence of in-hospital complications, and a favorable evolution in clinical follow-up.

The intake of fat and proteinwas higher in elder women than in all other groups. One third ofseniors took antihypertensive medications and 12% used lipidmodifying drugs.Conclusions: Different levels of prevention against CVDs andtheir risk factors shall be considered for various age groups ofpopulation. The findings of this study emphasize on the necessityof preventive measures against smoking and physical inactivity inyounger adults and dietary habits in seniors.

    Playing digital games has been associated with forms of addictive behavior. Past research on the subject has often been criticized on theoretical and empirical grounds, due mainly to measurement or sampling issues. The present study aims to overcome these two limitations, and presents data from a representative study in Germany using an already established instrument for measuring problematic game use. Large-scale, representative study using a computer-assisted telephone survey. Germany. A total of 580 adolescents between 14 and 18 years of age, 1866 younger adults between 19-39 years and 1936 older adults aged 40 years and older (overall n = 4382). Problematic game use was measured with the Gaming Addiction Short Scale (GAS), which covers seven criteria including salience, withdrawal and conflicts. Additionally, differential aspects of personality, as well as gaming behaviour, were measured. Only seven respondents [0.2%, 95% confidence interval (CI): 0.1, 0.3] met all criteria of the GAS Scale. In contrast, 3.7% (95% CI: 3.1, 4.3) of the respondents can be considered problematic users, meeting at least half these conditions. The percentage of problematic gamers among adolescents is above average (7.6%, 95% CI: 5.6, 10.1). High GAS scores are associated with aggression, low sociability and self-efficacy and lower satisfaction with life. Additionally, these scores correspond with intensive use and preferences for certain gaming genres across all age groups. Following Gaming Addiction Short Scale criteria, gaming addiction is currently not a widespread phenomenon among adolescents and adults in Germany. Gaming Addiction Short Scale scores are associated with intensive use, as well as certain problematic aspects of individuals' personalities and social lives. © 2012 The Authors, Addiction © 2012 Society for the Study of Addiction.

    This study explored age-related changes in gesture to better understand the relationship between gesture and word retrieval from memory. The frequency of gestures during tip-of-the-tongue (TOT) states highlights this relationship. There is a lack of evidence describing the form and content of iconic gestures arising spontaneously in such TOT states and a parallel gap addressing age-related variations. In this study, TOT states were induced in 45 participants from 2 age groups (older and younger adults) using a pseudoword paradigm. The type and frequency of gestures produced was recorded during 2 experimental conditions (single-word retrieval and narrative task). We found that both groups experienced a high number of TOT states, during which they gestured. Iconic co-TOT gestures were more common than noniconic gestures. Although there was no age effect on the type of gestures produced, there was a significant, task-specific age difference in the amount of gesturing. That is, younger adults gestured more in the narrative task, whereas older adults generated more gestures in the single-word-retrieval task. Task-specific age differences suggest that there are age-related differences in terms of the cognitive operations involved in TOT gesture production. (c) 2015 APA, all rights reserved.

    There has been a dramatic increase in internal migrant workers in China over recent decades, and there is a recent concern of poor mental health particularly amongst younger or "new generation" migrants who were born in 1980 or later. A cross-sectional study was conducted in Guangzhou city between May and July in 2012. Mental wellbeing was measured using the World Health Organization Five-item Well-Being Index Scale and the 36 Item Short Form Health Survey mental health scale. Linear and logistic regression models were used to investigate the differences between migrant workers and their urban counterparts and between younger and older migrants. Migrant workers (n = 914) showed a small but significant advantage in mental wellbeing compared to their urban counterparts (n = 814). There was some evidence for age modification effect (p for interaction = 0.055-0.095); better mental wellbeing in migrants than urbanites were mainly seen in the older compared to the younger group, and the difference attenuated somewhat after controlling for income satisfaction. Older migrants showed better mental health than younger migrants. Factors that were independently associated with poor mental health in migrants included being male, longer working hours, and income dissatisfaction, whilst older age, factory job, high income, and increased use of social support resources were associated with reduced risk. Efforts to promote mental health amongst migrant workers may be usefully targeted on younger migrants and include measures aimed to improve working conditions, strengthen the social support network, and address age-specific needs.

    The overall goal of this study was to obtain a greater understanding of the experiences of nurses aged under 30 in the New Zealand workforce with a view to developing age-appropriate retention strategies. Nurses aged under 30 constitute around 10% of the world's nursing workforce yet little is known about their experiences in the workplace. Poor retention of younger nurses is a cause for concern. The implications of the perceptions and needs of this generation of nurses must be considered in order to ensure effective succession planning. An explorative descriptive design framed within a broad qualitative methodology was utilized to explore experiences of younger nurses in the New Zealand workforce. Data were analysed thematically. Findings are reported under five themes: challenges of nursing, rewards of nursing, being young, coping and addressing generational differences. The study provides new knowledge about the experiences of younger nurses in the workforce and in particular the challenges facing younger Asian nurses. Managers and nurse leaders must address broader workforce issues as well as improving support for younger nurses to help improve younger nurse retention. Strategies designed to extend and challenge younger nurses in the workplace such as professional development and project work will also help, but will only be effective if nurses are given sufficient paid time to undertake this work. Being Asian provides added challenges for younger nurses in New Zealand and further research into the experiences of this subgroup is highly recommended. © 2012 The Authors.

    To investigate the prevalence of dental fluorosis in children who had participated in an oral health programme between the ages 2-5 years, including fluoride tablets from the age of 2 years. The study group consisted of 135 10- to 11-year-old children who had participated in the programme, including parent education, tooth-brushing instruction and prescribed fluoride tablets (0.25 mg NaF) (2-3 years: 1 tablet/day; 3-5 years: 2 tablets/day). The prevalence of dental fluorosis in the study group was compared with that in a nonintervention reference group consisting of 129 children of the same ages. The analysis was based on photos of the permanent maxillary front teeth using the Thylstrup & Fejerskov (TF) Index. No statistically significant difference in prevalence of dental fluorosis was seen between the two groups. Forty-three percent of the children in the study group and 38% in the reference group had fluorosis, the majority of a mild nature (TF-score 1). None had a TF score above 2. The pattern was the same after correction for parent reported intake of tablets at 3 and 5 years of age. Introduction of fluoride tablets at the age of 2 years did not result in increased prevalence of dental fluorosis.

    2012-08-01

    Allowing young learners to exert metacognitive control over learning often improves memory performance; however, little research has examined the consequences of giving older adults control over learning. In this study, younger and older adults studied word pairs before choosing half of the word pairs for restudy. Learners either restudied the items they chose (in the honor condition) or the items they did not choose (the dishonor condition; Kornell & Metcalfe, Journal of Experimental Psychology: Learning, Memory, and Cognition 32:609-622, 2006). Older and younger learners chose the same types of items for restudy, but the effectiveness of these choices differed greatly by age. For young learners, memory was superior in the honor condition, but older learners actually revealed numerically higher performance in the dishonor condition. This reveals a dramatic failure of metacognitive control, in the absence of any obvious monitoring deficit, in older adults. Implications for models of self-regulated learning are discussed.

    Little is known about the influence of vocal emotions on speech understanding. Word recognition accuracy for stimuli spoken to portray seven emotions (anger, disgust, fear, sadness, neutral, happiness, and pleasant surprise) was tested in younger and older listeners. Emotions were presented in either mixed (heterogeneous emotions mixed in a list) or blocked (homogeneous emotion blocked in a list) conditions. Three main hypotheses were tested. First, vocal emotion affects word recognition accuracy; specifically, portrayals of fear enhance word recognition accuracy because listeners orient to threatening information and/or distinctive acoustical cues such as high pitch mean and variation. Second, older listeners recognize words less accurately than younger listeners, but the effects of different emotions on intelligibility are similar across age groups. Third, blocking emotions in list results in better word recognition accuracy, especially for older listeners, and reduces the effect of emotion on intelligibility because as listeners develop expectations about vocal emotion, the allocation of processing resources can shift from emotional to lexical processing. Emotion was the within-subjects variable: all participants heard speech stimuli consisting of a carrier phrase followed by a target word spoken by either a younger or an older talker, with an equal number of stimuli portraying each of seven vocal emotions. The speech was presented in multi-talker babble at signal to noise ratios adjusted for each talker and each listener age group. Listener age (younger, older), condition (mixed, blocked), and talker (younger, older) were the main between-subjects variables. Fifty-six students (Mage= 18.3 years) were recruited from an undergraduate psychology course; 56 older adults (Mage= 72.3 years) were recruited from a volunteer pool. All participants had clinically normal pure-tone audiometric thresholds at frequencies ≤3000 Hz. There were significant main effects of

    Unzen volcano is situated in a volcanotectonic depression, ~70 km west of the volcanic front of SW Japan. The volcanic products of Unzen volcano cover a wide area with many lava domes, thick lava flows, and pyroclastic deposits of andesite to dacite composition. The composite volcanic edifice can be subdivided into Older and Younger Unzen volcanoes. The Older Unzen volcano (500-200 ka) is thought to be a complex volcanic edifice originally centered near the present Younger Unzen volcano, but it has been displaced by several faults and deeply eroded. The Younger Unzen volcano (soil organic carbon of bulk sample underlying the volcanic eruption products. The 14C dating of the bulk soil organic matter is a polemic subject, mainly due to the complexity of the soil formation and to the variable contamination from several sources. The reliabilty of most 14C dates for buried soils in this study was supported by lack of significant age deviations in double organic extracts of soil (humin and humic acid fractions), agreement of dating results obtained for different materials (buried soil and charcoal), and normal sequence in soil-pyroclastic/lava sections. The 14C results based on surface and USDP borehole materials clarified the initial eruption ages of the Younger Unzen volcano, i.e., Myokendake: 35 ka; Fugendake: 25 ka; and Mayuyama: 4.5 ka BP. In particular, the Fugendake volcano is characterized by the repeated eruptions occurred at 24, 20, 19, 14, 11, 10, 9, 7, 4, 1.6 ka BP and recently AD 1300, 1663, 1792 and 1991 ~95.

    Late-life depression may differ from early-life depression in its phenomenology. To investigate the effect of age on the phenomenology of major depression. A systematic search was conducted in PubMed, Embase and PsycINFO for all studies examining the relation between age and phenomenology of major depression according to RDC, DSM and ICD criteria. Studies were included only if the age groups were compared at the single-item level using the 17-, 21- or 24-item versions of the Hamilton Rating Scale for Depression; a meta-analysis was done for each item of the 17-item scale. Eleven papers met the inclusion criteria. Older depressed adults, compared with younger depressed adults, demonstrated more agitation, hypochondriasis and general as well as gastrointestinal somatic symptoms, but less guilt and loss of sexual interest. The phenomenology of late-life depression differs only in part from that of early-life depression. Major depression in older people may have a more somatic presentation, whereas feelings of guilt and loss of sexual function may be more prevalent in younger people.

    To describe in children younger than the present US FDA-approved 5 years of age the thickest part of the temporal bone available for placement of a bone-anchored hearing system. Children with unilateral hearing loss, as with aural atresia, have deficits in at least language comprehension and oral expression. The early provision of hearing to the atretic ear may minimize the potential for auditory deprivation. Point prevalence descriptive study. Tertiary referral pediatric hospital. Thirty-eight patients less than 6 years old with congenital aural atresia had undergone temporal bone computed tomography (CT). Bone thickness lateral (ie, superficial) to the sinodural angle, in the topmost axial CT slice that included any adjacent petrous ridge, was measured. The mean bone thicknesses lateral to the sinodural angles of the atretic ears were 5.1, 5.0, 5.9, 5.2, 5.2, and 4.8 mm for the bone thickness lateral (ie, superficial) to the sinodural angle is sufficient for many children suffering from aural atresia to have bone-anchored hearing devices implanted younger than age 5 years. Use of the sinodural site would require a magnetic bone-anchored hearing system, which could be repositioned posteriorly at age 5 years when pinna construction and atresiaplasty endeavors typically begin. © American Academy of Otolaryngology—Head and Neck Surgery Foundation 2014.

    Purpose: To directly compare (1) radiation treatment utilization patterns; (2) risks of subsequent mastectomy; and (3) costs of radiation treatment in patients treated with brachytherapy versus whole-breast irradiation (WBI), in a national, contemporary cohort of women with incident breast cancer, aged 64 years and younger. Methods and Materials: Using MarketScan health care claims data, we identified 45,884 invasive breast cancer patients (aged 18-64 years), treated from 2003 to 2010 with lumpectomy, followed by brachytherapy (n=3134) or whole-breast irradiation (n=42,750). We stratified patients into risk groups according to age (Age<50 vs Age≥50) and endocrine therapy status (Endocrine− vs Endocrine+). “Endocrine+” patients filled an endocrine therapy prescription within 1 year after lumpectomy. Pathologic hormone receptor status was not available in this dataset. In brachytherapy versus WBI patients, utilization trends and 5-year subsequent mastectomy risks were compared. Stratified, adjusted subsequent mastectomy risks were calculated using proportional hazards regression. Results: Brachytherapy utilization increased from 2003 to 2010: in patients Age<50, from 0.6% to 4.9%; patients Age≥50 from 2.2% to 11.3%; Endocrine− patients, 1.3% to 9.4%; Endocrine+ patients, 1.9% to 9.7%. Age influenced treatment selection more than endocrine status: 17% of brachytherapy patients were Age<50 versus 32% of WBI patients (P<.001); whereas 41% of brachytherapy patients were Endocrine–versus 44% of WBI patients (P=.003). Highest absolute 5-year subsequent mastectomy risks occurred in Endocrine−/Age<50 patients (24.4% after brachytherapy vs 9.0% after WBI (hazard ratio [HR] 2.18, 95% confidence interval [CI] 1.37-3.47); intermediate risks in Endocrine−/Age≥50 patients (8.6% vs 4.9%; HR 1.76, 95% CI 1.26-2.46); and lowest risks in Endocrine+ patients of any age: Endocrine+/Age<50 (5.5% vs 4.5%; HR 1.18, 95% CI 0.61-2.31); Endocrine+/Age≥50 (4.2% vs 2

    Full Text Available Introduction. The data on the health-condition of the first permanent molars among children in our region is scarce. Therefore, the need for more thorough analysis of the state of health of these teeth in the children from our region imposes itself, along with the need to determine the most critical period in which a significant increase in caries prevalence of these teeth takes place. Aim. The aim of the research was to perform a comparative analysis of the prevalence, average rate and structure of decay, missed and filled first permanent molars in the children of the younger school age in relation to those of the older school age. Material and methods. The research included 1.119 examinees, aged from 7 to 14 years. Examinees were divided into two groups according to their age: examinees of the younger school age and older school age. Dental check-up of the students was performed by means of a dental probe and mirror and the health condition of the examined teeth was registered by means of Klein-Palmer's DMF system. Results. The research determined high values of the examined parameters of the first permanent molars caries prevalence which increases with the age of the examinees. In the examinees of the age of 8, 9, and 10, statistically more significant values of the examined teeth caries prevalence parameters were registered, in relation to the examinees of seven years of age. In the examinees of the older school age, statistically significantly higher values were registered only for TCI and ACI and only in the examinees aged 14 in relation to the examinees aged 11. With the age, the percent of decay is decreases, while the percent of filled and extracted first permanent molars increases. Conclusion. Results show that the period between 7 and 10 years of age is the most critical and the most important period for the implementation of preventive-prophylactic measures aimed to preserve the health of the first permanent molars.

    A boxmodel of the Great Lakes is used to estimate meltwater flow into the North Atlantic between 8000 and 14,000 calendar years B.P. Controls on the model include the oxygen isotopic composition of meltwaters and lake waters as measured in the shells of ostracodes. Outflow rates are highest when oxygen isotopic values of the lake waters are most negative, denoting a maximum glacial meltwater component. Flow rates reach maximum values before the onset of the Younger Dryas and after it ends. These maxima appear to be correlative with the major meltwater pulses MWP 1A and 1B. Although the resumption of North Atlantic Deep Water formation may be tied to the reduction in ice sheet melting, neither the onset nor the end of the Younger Dryas, as recorded in the Greenland Ice Sheet Project (GISP2) records, appear tied to maxima in meltwater outflow from the Laurentide ice sheet.

    This study examined how younger and older adults approach simple and complex computerized writing tasks. Nineteen younger adults (age range 21-31, mean age 26.1) and 19 older adults (age range 65-83, mean age 72.1) participated in the study. Typing speed, quantitative measures of outcome and process, and self-corrections were recorded. Younger adults spent a lower share of their time on actual typing, and demonstrated more prevalent use of delete keys than did older adults. Within the older group, there was no correlation between the total time spent on the entire task and the number of corrections, but increased typing speed was related to more errors. The results suggest that the approach to the task was different across age groups, either because of age or because of cohort effects. We discuss the interplay of speed and accuracy with regard to digital writing, and its implications for the design of human-computer interactions.

  10. An fMRI comparison of neural activity associated with recognition of familiar melodies in younger and older adults

    2015-10-01

    Full Text Available Several studies of semantic memory in non-musical domains involving recognition of items from long-term memory have shown an age-related shift from the medial temporal lobe structures to the frontal lobe. However, the effects of aging on musical semantic memory remain unexamined. We compared activation associated with recognition of familiar melodies in younger and older adults. Recognition follows successful retrieval from the musical lexicon that comprises a lifetime of learned musical phrases. We used the sparse-sampling technique in fMRI to determine the neural correlates of melody recognition by comparing activation when listening to familiar versus unfamiliar melodies, and to identify age differences. Recognition-related cortical activation was detected in the right superior temporal, bilateral inferior and superior frontal, left middle orbitofrontal, bilateral precentral, and left supramarginal gyri. Region-of-interest analysis showed greater activation for younger adults in the left superior temporal gyrus and for older adults in the left superior frontal, left angular, and bilateral superior parietal regions. Our study provides powerful evidence for these musical memory networks due to a large sample (N = 40 that includes older adults. This study is the first to investigate the neural basis of melody recognition in older adults and to compare the findings to younger adults.

    Magnetic resonance cholangiopancreatography (MRCP) could aid in the diagnosis of biliary atresia, a hepatic pathology with thin, irregular or interrupted biliary ducts. There is little published evidence of MRCP appearances in normal neonates and young infants. To assess the use of MR cholangiopancreatography in visualizing the biliary tree in neonates and infants younger than 3 months with no hepatobiliary disorder, and to assess this visibility in relationship to the child's age, weight, and sedation and fasting states. Between December 2008 and October 2010 our department performed MRI of the brain, orbits and face on 16 full-term neonates and infants. Each child was younger than 3 months (90 days) and without any hepatobiliary disorders. The children were scanned with a respiratory-gated 0.54 x 0.51 x 0.4-mm{sup 3} 3-D MRCP sequence. We used a reading grid to assess subjectively the visibility of the extrahepatic bile ducts along with extrahepatic bile duct confluence. The visibility of the extrahepatic bile duct confluence was assessed against age, weight, and sedation and fasting states. The extrahepatic bile duct confluence was seen in 10 children out of 16 (62.5%). In the neonate sub-group (corrected age younger than 30 days), the MRCP was technically workable and the extrahepatic bile duct confluence was seen in four cases out of eight (50%). This visualization was up to 75% in the subgroup older than 30 days. However, statistically there was no significant difference in visibility of the extrahepatic bile duct confluence in relationship to age, weight or MRCP performance conditions (feeding, fasting or sedation). The complete normal biliary system (extrahepatic bile duct confluence included) is not consistently visualized in infants younger than 3 months old on non-enhanced MRCP. Thus the use of MRCP to exclude a diagnosis of biliary atresia is compromised at optimal time of surgery. (orig.)

    OBJECTIVE: To investigate differences in diagnostic subtypes of bipolar disorder as according to ICD-10 between patients whose first contact with psychiatric health care occurs late in life (over 50 years of age) and patients who have first contact earlier in life (50 years of age or below......). METHODS: From 1994 to 2002 all patients who received a diagnosis of a manic episode or bipolar disorder at initial contact with the mental healthcare system, whether outpatient or inpatient, were identified in Denmark's nationwide register. RESULTS: A total of 852 (49.6%) patients, who were over age 50......, and 867 patients, who were 50 or below, received a diagnosis of a manic episode or bipolar disorder at the first contact ever. Older inpatients presented with psychotic symptoms (35.4%) significantly less than younger inpatients (42.6%) due specifically to a lower prevalence of manic episodes...

  13. Core-collapse supernovae and the Younger Dryas/terminal Rancholabrean extinctions

    2011-09-01

    Early predictions that some supernovae release large quantities of prompt high energy photons are now corroborated by optical identification of core-collapse supernovae associated with extragalactic GRBS (beamed γ-ray bursts) and XRFS (beamed or un-beamed X-ray flashes). Given the in-galaxy supernova frequency and GRB and XRF recurrence statistics, significant Earth-incident events during the past several million years very likely occurred and nearby events should have affected the Earth and other planetary atmospheres, including terrestrial surface solar UV, the Earth's climate, and its ecology. The Younger Dryas Stadial (˜12,900 to 11,550 calendar yr BP) began with sharply cooler temperatures in the Earth's northern hemisphere, regional drought, paleoecological evidence compatible with increased UV, and abrupt increases in cosmogenic 14C and 10Be in ice and marine cores and tree rings. In North America, stratigraphic and faunal sequences indicate that a major pulse of mammalian extinctions (at least 23-31 genera) began very close to 12,830 calendar yr BP and was sudden: deposits one century younger are devoid of diverse extinct fauna remains. A 10 s beamed GRB within 2 kpc of the Earth delivers 100 kJ m -2 fluence to the Earth's atmosphere, where it causes spallation and catalytic reactions depleting 35-50% O 3, and producing excess NO x species (which favor cooling, drought, and surface fertility), 14C, and 10Be. An un-beamed, 10 50 erg hard photon impulse at ˜250 pc produces similar terrestrial atmospheric effects. A well-characterized massive star supernova, the unusually close Vela event ( d = 250 ± 30 pc; total energy of 1-2 × 10 51 erg; age constrained from remnant nebula shock velocities considerations at 13,000-16,000 yr and from the pulsar characteristic age at ˜11,400 yr) may have initiated the Younger Dryas climate change, and caused the extinction of the terminal Rancholabrean fauna.

    Increased mortality has been documented in older homeless veterans. This retrospective study examined mortality and cause of death in a cohort of young and middle-aged homeless veterans. We examined US Department of Veterans Affairs records on homelessness and health care for 2000-2003 and identified 23 898 homeless living veterans and 65 198 non-homeless living veterans aged 30-54. We used National Death Index records to determine survival status. We compared survival rates and causes of death for the 2 groups during a 10-year follow-up period. A greater percentage of homeless veterans (3905/23 898, 16.3%) than non-homeless veterans (4143/65 198, 6.1%) died during the follow-up period, with a hazard ratio for risk of death of 2.9. The mean age at death (52.3 years) for homeless veterans was approximately 1 year younger than that of non-homeless veterans (53.2 years). Most deaths among homeless veterans (3431/3905, 87.9%) and non-homeless veterans (3725/4143, 89.9%) were attributed to 7 cause-of-death categories in the International Classification of Diseases, 10th Revision (cardiovascular system; neoplasm; external cause; digestive system; respiratory system; infectious disease; and endocrine, nutritional, and metabolic diseases). Death by violence was rare but was associated with a significantly higher risk among homeless veterans than among non-homeless veterans (suicide hazard ratio = 2.7; homicide hazard ratio = 7.6). Younger and middle-aged homeless veterans had higher mortality rates than those of their non-homeless veteran peers. Our results indicate that homelessness substantially increases mortality risk in veterans throughout the adult age range. Health assessment would be valuable for assessing the mortality risk among homeless veterans regardless of age.

    We compared the age at admission and the severity of illness of hospitalized Micronesians with 3 other racial/ethnic groups in Hawaii. With Hawaii Health Information Corporation inpatient data, we determined the age at admission and the severity of illness for 162,152 adult, non-pregnancy-related hospital discharges in Hawaii from 2010 to 2012. We performed multivariable linear regression analyses within major disease categories by racial/ethnic group. We created disease categories with all patient refined-diagnosis related groups. Hospitalized Micronesians were significantly younger at admission than were comparison racial/ethnic groups across all patient refined-diagnosis related group categories. The severity of illness for Micronesians was significantly higher than was that of all comparison racial/ethnic groups for cardiac and infectious diseases, higher than was that of Whites and Japanese for cancer and endocrine hospitalizations, and higher than was that of Native Hawaiians for substance abuse hospitalizations. Micronesians were hospitalized significantly younger and often sicker than were comparison populations. Our results will be useful to researchers, state governments, and hospitals, providers, and health systems for this vulnerable group.

    This study examines the neural mechanisms through which younger and older adults ignore irrelevant information, a process that is necessary to effectively encode new memories. Some age-related memory deficits have been linked to a diminished ability to dynamically gate sensory input, resulting in problems inhibiting the processing of distracting stimuli. Whereas oscillatory power in the alpha band (8–12Hz) over visual cortical areas is thought to dynamically gate sensory input in younger adul...

    Full Text Available Background. This study aimed to evaluate Pediatric Appendicitis Score (PAS, diagnostic delay, and factors responsible for possible late diagnosis in children <4 years compared with older children who were operated on for suspected appendicitis. Method. 122 children, between 1 and 14 years, operated on with appendectomy for suspected appendicitis, were retrospectively analyzed. The cohort was divided into two age groups: ≥4 years (n=102 and <4 years (n=20. Results. The mean PAS was lower among the younger compared with the older patients (5.3 and 6.6, resp.; P=0.005, despite the fact that younger children had more severe appendicitis (75.0% and 33.3%, resp.; P=0.001. PAS had low sensitivity in both groups, with a significantly lower sensitivity among the younger patients. Parent and doctor delay were confirmed in children <4 years of age with appendicitis. PAS did not aid in patients with doctor delay. Parameters in patient history, symptoms, and abdominal examination were more diffuse in younger children. Conclusion. PAS should be used with caution when examining children younger than 4 years of age. Diffuse symptoms in younger children with acute appendicitis lead to delay and to later diagnosis and more complicated appendicitis.

    Limited data exist about blood lead levels (BLLs) and potential exposures among children living in Puerto Rico. The Puerto Rico Department of Health has no formal blood lead surveillance program. We assessed the prevalence of elevated BLLs (≥5 micrograms of lead per deciliter of blood), evaluated household environmental lead levels, and risk factors for BLL among children younger than 6 years of age living in Puerto Rico in 2010. We used a population-based, cross-sectional sampling strategy to enroll an island-representative sample of Puerto Rican children younger than 6 years. We estimated the island-wide weighted prevalence of elevated BLLs and conducted bivariable and multivariable linear regression analyses to ascertain risk factors for elevated BLLs. The analytic data set included 355 households and 439 children younger than 6 years throughout Puerto Rico. The weighted geometric mean BLL of children younger than 6 years was 1.57 μg/dL (95% confidence interval [CI], 1.27-1.88). The weighted prevalence of children younger than 6 years with BLLs of 5 μg/dL or more was 3.18% (95% CI, 0.93-5.43) and for BLLs of 10 μg/dL or more was 0.50% (95% CI, 0-1.31). Higher mean BLLs were significantly associated with data collection during the summer months, a lead-related activity or hobby of anyone in the residence, and maternal education of less than 12 years. Few environmental lead hazards were identified. The prevalence of elevated BLLs among Puerto Rican children younger than 6 years is comparable with the most recent (2007-2010) US national estimate (BLLs ≥5 μg/dL = 2.6% [95% CI = 1.6-4.0]). Our findings suggest that targeted screening of specific higher-risk groups of children younger than 6 years can replace island-wide or insurance-specific policies of mandatory blood lead testing in Puerto Rico.

  1. Younger and Older Users’ Recognition of Virtual Agent Facial Expressions

    2015-01-01

    As technology advances, robots and virtual agents will be introduced into the home and healthcare settings to assist individuals, both young and old, with everyday living tasks. Understanding how users recognize an agent’s social cues is therefore imperative, especially in social interactions. Facial expression, in particular, is one of the most common non-verbal cues used to display and communicate emotion in on-screen agents (Cassell, Sullivan, Prevost, & Churchill, 2000). Age is important to consider because age-related differences in emotion recognition of human facial expression have been supported (Ruffman et al., 2008), with older adults showing a deficit for recognition of negative facial expressions. Previous work has shown that younger adults can effectively recognize facial emotions displayed by agents (Bartneck & Reichenbach, 2005; Courgeon et al. 2009; 2011; Breazeal, 2003); however, little research has compared in-depth younger and older adults’ ability to label a virtual agent’s facial emotions, an import consideration because social agents will be required to interact with users of varying ages. If such age-related differences exist for recognition of virtual agent facial expressions, we aim to understand if those age-related differences are influenced by the intensity of the emotion, dynamic formation of emotion (i.e., a neutral expression developing into an expression of emotion through motion), or the type of virtual character differing by human-likeness. Study 1 investigated the relationship between age-related differences, the implication of dynamic formation of emotion, and the role of emotion intensity in emotion recognition of the facial expressions of a virtual agent (iCat). Study 2 examined age-related differences in recognition expressed by three types of virtual characters differing by human-likeness (non-humanoid iCat, synthetic human, and human). Study 2 also investigated the role of configural and featural processing as a

    The Women's Health Initiative Memory Study-Younger (WHIMS-Y) was designed to assess the effect of prior random assignment to hormone therapy (HT) (conjugated equine estrogen (CEE) alone or CEE plus medroxyprogesterone acetate (MPA)) on global cognitive function in younger middle-aged women relative to placebo. WHIMS-Y was an ancillary study to the Women's Health Initiative (WHI) HT trial and enrolled 1361 women who were aged 50-55 years and postmenopausal at WHI enrollment. WHIMS-Y will examine whether an average of 5.4 years of HT during early menopause has longer term protective effects on global cognitive function and if these effects vary by regimen, time between menopause and study initiation, and prior use of HT. We present the study rationale and design. We describe enrollment, adherence to assigned WHI therapy, and compare risk factor characteristics of the WHIMS-Y cohort at the time of WHI enrollment to similar aged women in the WHI HT who did not enroll in WHIMS-Y. Challenges of WHIMS-Y include lower than expected and differential enrollment. Strengths of WHIMS-Y include balance in baseline risk factors between treatment groups, standardized and masked data collection, and high rates of retention and on-trial adherence and exposure. In addition, the telephone-administered cognitive battery showed adequate construct validity. WHIMS-Y provided an unprecedented chance to examine the hypothesis that HT may have protective effects on cognition in younger postmenopausal women aged 50-55 years. Integrated into the WHI, WHIMS-Y optimized the experience of WHI investigators to ensure high retention and excellent quality assurance across sites.

  3. Vocabulary influences older and younger listeners' processing of dysarthric speech.

    2013-08-01

    This study examined younger (n = 16) and older (n = 16) listeners' processing of dysarthric speech-a naturally occurring form of signal degradation. It aimed to determine how age, hearing acuity, memory, and vocabulary knowledge interacted in speech recognition and lexical segmentation. Listener transcripts were coded for accuracy and pattern of lexical boundary errors. For younger listeners, transcription accuracy was predicted by receptive vocabulary. For older listeners, this same effect existed but was moderated by pure-tone hearing thresholds. While both groups employed syllabic stress cues to inform lexical segmentation, older listeners were less reliant on this perceptual strategy. The results were interpreted to suggest that individuals with larger receptive vocabularies, with their presumed greater language familiarity, were better able to leverage cue redundancies within the speech signal to form lexical hypothesis-leading to an improved ability to comprehend dysarthric speech. This advantage was minimized as hearing thresholds increased. While the differing levels of reliance on stress cues across the listener groups could not be attributed to specific individual differences, it was hypothesized that some combination of larger vocabularies and reduced hearing thresholds in the older participant group led to them prioritize lexical cues as a segmentation frame.

    Age-related differences in cognitive performance are well documented. These differences are most pronounced during tasks with high demands on cognitive control, and it has been proposed that selective alteration of prefrontal activity is associated with cognitive changes in old age. Here, differences in the neural systems underlying selection requirements for older and younger adults were investigated using functional magnetic resonance imaging (fMRI). A verb generation task was used, and selection requirements were varied with regard to whether each noun could be associated with either few (scissors-cut) or many (ball-bounce, kick, throw...) competing alternatives. The two age groups showed statistically equivalent behavioral performance across the task conditions but marked differences in activation. Across both age groups, high selection demands activated several regions including bilateral frontal, left anterior frontal, left inferior temporal regions, and the dorsal anterior cingulate cortex (ACC). Between-group comparisons using region-of-interest analyses revealed less activation for senior adults in left inferior frontal gyrus (IFG), left inferior temporal gyrus, and the anterior cingulate and higher activation in right inferior frontal gyrus compared to young adults. These findings indicate age-related changes in multiple regions contributing to aspects of selection requirements during verb generation.

    This study was an unobtrusive observational analysis of 333 older and younger bus passengers in Guadalajara, Mexico. A set of data were collected for each observed passenger, as well as more general observations related to driver behaviour, bus design and bus service characteristics. There were significant differences between older and younger passengers in terms of boarding and alighting times, use of handrails, seat location preferences, passenger stability and coping strategies in order to maintain postural stability. The conditions of travel are conducive to a poor passenger experience for the older passengers in particular. Although the problems may be attributed to bus design and driver behaviour typical of that in developing countries, they are also influenced by the wider transport infrastructure, and a lack of a regulatory regime which places drivers under time pressure and in direct competition with each other. Practitioner Summary: Bus services must cater for all ages of passengers, including the elderly. This unobtrusive observational study investigated the passenger experience in a developing world city. Bus and wider service design were found to compromise the journey experience, with the older users being particularly negatively impacted. Design recommendations are provided.

    2011-01-01

    The current study incorporated a lifespan perspective into existing theories of intrusive thoughts to examine age-related differences in the difficulty controlling intrusive thoughts, the distress following intrusive thought recurrences, and the meanings assigned to these recurrences. Younger (N = 51) and older (N = 49) community adults were randomly assigned to suppress (i.e., keep out of mind) or monitor an intrusive thought. Participants rated their positive and negative affect throughout engagement with the intrusive thought, and also rated the meanings they gave to recurrences of their everyday intrusive thoughts. The results demonstrated that older adults tended to perceive greater difficulty with controlling the intrusive thought than younger adults, despite not differing in the actual recurrence of the intrusive thought. With regard to distress, ooHAcrosslder adults experienced steadier levels of positive affect than younger adults throughout engagement with the intrusive thought. However, older adults also reported greater residual negative affect after engaging with the intrusive thought than younger adults. Finally, older and younger adults appeared to assign meanings to recurrences of intrusive thoughts in line with age-relevant concerns. Specifically, older adults were prone to interpret the recurrence of intrusive thoughts as a sign of cognitive decline, but were less likely than younger adults to see intrusive thoughts as a sign of moral failure. Together, these results highlight a range of potential risk and protective factors in older adults for experiencing emotion dysregulation after intrusive thoughts. PMID:21707184

    Age-related differences in memory monitoring appear when people learn emotional words. Namely, younger adults' judgments of learning (JOLs) are higher for positive than neutral words, whereas older adults' JOLs do not discriminate between positive versus neutral words. In two experiments, we evaluated whether this age-related difference extends to learning positive versus neutral pictures. We also evaluated the contribution of two dimensions of emotion that may impact younger and older adults' JOLs: valence and arousal. Younger and older adults studied pictures that were positive or neutral and either high or low in arousal. Participants made immediate JOLs and completed memory tests. In both experiments, the magnitude of older adults' JOLs was influenced by emotion, and both younger and older adults demonstrated an emotional salience effect on JOLs. As important, the magnitude of participants' JOLs was influenced by valence, and not arousal. Emotional salience effects were also evident on participants' free recall, and older adults recalled as many pictures as did younger adults. Taken together, these data suggest that older adults do not have a monitoring deficit when learning positive (vs. neutral) pictures and that emotional salience effects on younger and older adults' JOLs are produced more by valence than by arousal.

    We studied the prevalence as well as the sociodemographic characteristics and QOL of older adults (> 50 years) with irritable bowel syndrome (IBS) among the population at large and compared it to their younger counterparts'. We hypothesized that IBS is less prevalent among older persons and they suffer poorer QOL compared to younger IBS patients. A total of 1000 adults from nine sites, including a medical center, churches, and a blood bank in our metropolitan area (670 African Americans, 320 Caucasians, and 10 others), completed self-administered questionnaires providing sociodemographic information and details regarding bowel habits and associated symptoms for diagnosing the IBS based on Rome II criteria. QOL was assessed by the SF-12 questionnaire. The study database was divided into two groups, younger ( or = 50 years). The two age groups were similar with respect to gender and household income. Ninety-five of the 1000 participants had IBS, giving a total sample prevalence of 9.5% ( or = 50 years, 7.6%). The prevalence of IBS was similar in the two groups irrespective of race, sex, marital status, size of household, location of residence (rural versus urban), level of educational status, and household income. Compared to the older group, there was a trend toward a higher prevalence of IBS among divorced subjects (12.7% vs 0%; P = 0.1) and those below poverty level of income (15.3% vs 7.5%; P = 0.09) in the younger subjects. In contrast, older IBS patients were more likely to attend church regularly (32.5% vs 58.8%; P food intolerance, and drug allergies between the two groups. Health care utilization was similar between the two IBS groups in terms of number of physician visits, use of prescription and alternative medications, and being disabled due to IBS. There was no difference in the overall QOL score means (27.8 vs 29.5; P = NS) or in its general health and physical functioning components. However, older IBS patients had better social functioning (9.1 vs 9

    Phishing is the spoofing of Internet websites or emails aimed at tricking users into entering sensitive information, with such goals as financial or identity theft. The current study sought to determine whether age is associated with increased susceptibility to phishing and whether tests of executive functioning can predict phishing susceptibility. A total of 193 cognitively intact participants, 91 younger adults and 102 older adults, were primarily recruited through a Psychology department undergraduate subject pool and a gerontology research registry, respectively. The Executive Functions Module from the Neuropsychological Assessment Battery and the Iowa Gambling Task were the primary cognitive predictors of reported phishing suspiciousness. Other predictors included age group (older vs. younger), sex, education, race, ethnicity, prior knowledge of phishing, prior susceptibility to phishing, and whether or not browsing behaviors were reportedly different in the laboratory setting versus at home. A logistic regression, which accounted for a 22.7% reduction in error variance compared to the null model and predicted phishing suspiciousness with 73.1% (95% CI [66.0, 80.3]) accuracy, revealed three statistically significant predictors: the main effect of education (b = 0.58, SE = 0.27) and the interactions of age group with prior awareness of phishing (b = 2.31, SE = 1.12) and performance on the Neuropsychological Assessment Battery Mazes test (b = 0.16, SE = 0.07). Whether or not older adults reported being suspicious of the phishing attacks used in this study was partially explained by educational history and prior phishing knowledge. This suggests that simple educational interventions may be effective in reducing phishing vulnerability. Although one test of executive functioning was found useful for identifying those at risk of phishing susceptibility, four tests were not found to be useful; these results speak to the need for more ecologically valid tools in

    Full Text Available High intakes of fat have been linked to greater cognitive decline in old age, but such associations may already occur in younger adults. We tested memory and learning in 38 women (25-45 years old, recruited for a larger observational study in women with polycystic ovary syndrome. These women varied in health status, though not significantly between cases (n=23 and controls (n=15. Performance on tests sensitive to medial temporal lobe function (CANTABeclipse, Cambridge Cognition Ltd., i.e. verbal memory, visuo-spatial learning and delayed pattern matching, were compared with intakes of macronutrients from 7-day diet diaries and physiological indices of metabolic syndrome. Partial correlations were adjusted for age, activity and verbal IQ (National Adult Reading Test. Greater intakes of saturated and trans fats, and higher saturated to unsaturated fat ratio (Sat:UFA, were associated with more errors on the visuo-spatial task and with poorer word recall and recognition. Unexpectedly, higher UFA intake predicted poorer performance on the word recall and recognition measures. Fasting insulin was positively correlated with poorer word recognition only, whereas higher blood total cholesterol was associated only with visuo-spatial learning errors. None of these variables predicted performance on a delayed pattern matching test. The significant nutrient-cognition relationships were tested for mediation by total energy intake: saturated and trans fat intakes, and Sat:UFA, remained significant predictors specifically of visuo-spatial learning errors, whereas total fat and UFA intakes now predicted only poorer word recall. Examination of associations separately for mono- (MUFA and polyunsaturated fats suggested that only MUFA intake was predictive of poorer word recall. Saturated and trans fats, and fasting insulin, may already be associated with cognitive deficits in younger women. The findings need extending but may have important implications for public

Fifteen children with dysarthria and CP (nine males, six females; age range 5-11 y, mean age 8 y, SD 2 y; CP type: eight spastic, four dyskinetic, one ataxia, two Worster Drought syndrome; Gross Motor Function Classification System levels II-IV, median level II) participated in this study. Children received three sessions of individual therapy per week for 6 weeks. Intelligibility of single words and connected speech was compared across five points: 1 and 6 weeks before therapy and 1, 6, and 12 weeks after therapy. Three familiar listeners and three unfamiliar listeners scored each recording. Participation in communicative interactions was measured using the Focus on the Outcomes of Communication Under Six (FOCUS) tool. Analyses of variance and paired t-tests were used to investigate change. Mean speech intelligibility increased after therapy to familiar listeners (single words 10.8%, 95% confidence interval [CI] 7.2-14.4; connected speech 9.4%, 95% CI 4.8-14.1) and unfamiliar listeners (single words 9.3%, 95% CI 6.8-11.8; connected speech 10.5%, 95% CI 7.3-13.8). FOCUS scores increased following therapy for parents (mean increase 30.3, 95% CI 10.2-50.4) and for teachers (28.25, 95% CI 14.4-42.1), but changes did not correlate with intelligibility. A wide variation was seen in individual responses to therapy. Brief intensive therapy is associated with gains in intelligibility and communicative interactions for some younger children with dysarthria. © The Authors.

    Management of diabetes in elderly subjects is complex and careful management of glucose levels is of particular importance in this population because of an increased risk of diabetes-related complications and hypoglycaemia. The aim of this study was to evaluate the pharmacokinetic and pharmacodynamic properties of insulin degludec (IDeg), a basal insulin with an ultra-long duration of action, in elderly subjects with type 1 diabetes compared with younger adults. This trial was a randomised, double-blind, two-period, crossover trial conducted in a single centre and included both inpatient and outpatient periods. Subjects were men and women aged 18-35 years inclusive (younger adult group) or ≥65 years (elderly group) with type 1 diabetes who received IDeg (0.4 U/kg) via subcutaneous injection in the thigh once-daily for six days. Following 6-day dosing, a 26-hour euglycaemic glucose clamp procedure was conducted to evaluate the steady-state pharmacodynamic effects of IDeg. Blood samples were taken for pharmacokinetic analysis up to 120 h post-dose. Pharmacokinetic endpoints included the total exposure of IDeg, ie the area under the IDeg serum concentration curve during one dosing interval at steady state (AUC(IDeg,τ,SS)) (τ = 0-24 h, equal to one dosing interval) and the maximum IDeg serum concentration at steady state (C(max,IDeg,SS)). Pharmacodynamic endpoints included the total glucose-lowering effect of IDeg, ie the area under the glucose infusion rate (GIR) curve at steady state (AUC(GIR,τ,SS)), and the maximum GIR at steady state (GIR(max,IDeg,SS)). Total exposure (AUC(IDeg,τ,SS)) and maximum concentration (C(max,IDeg,SS)) of IDeg were comparable between elderly subjects and younger adults. Estimated mean age group ratios (elderly/younger adult) for AUC(IDeg,τ,SS) and C(max,IDeg,SS) and corresponding two-sided 95 % confidence intervals (CIs) were 1.04 (95 % CI 0.73-1.47) and 1.02 (95 % CI 0.74-1.39), respectively.

    The parameters of the optic disc and peripapillary retinal nerve fibre layer (pRNFL) in children may vary with disease processes that contribute to visual impairment and blindness and so could be useful as an objective measure in at-risk children. There is no standardised reference for the normal parameters of the optic disc and pRNFL in children; however, there are a large number of small individual studies that have been undertaken to look at these measures. A systematic review of current literature on the range of pRNFL and optic disc parameters in children aged less than 18 years will be performed. Studies will be considered for review if they report numerical data on optic disc and pRNFL parameters, measured using optical coherence tomography. Outcome measures will include mean pRNFL thickness and cup-disc ratio. The bibliographic databases Medline, CINAHL, EMBASE, Scopus and Web of Science will be systematically searched from 1991. Screening of search results will be conducted by two authors working independently, as will extraction of primary and secondary outcome data. Ten per cent of all other data extraction will be checked by a second author. Results will be compiled and presented in evidence tables. Where possible and appropriate, study-specific estimates will be combined to obtain an overall summary estimate of pRNFL thickness and cup-disc ratio across studies and results will be presented by age of population. Subgroup analyses will be undertaken for children of different ethnicities. This review aims to provide an overview of the parameters of the optic disc and pRNFL in children of different ages in order to identify gaps in knowledge and to improve understanding of what might be considered within/outside the range of normality. The findings will be presented in peer-reviewed journals and will be presented at conferences. PROSPERO CRD42016033068.

    Service planning for people with younger onset dementia (YOD; an onset of symptoms before the age of 65 years) relies on prevalence estimates, with existing models based upon older people. This pilot study investigated the prevalence and causes of YOD in a defined catchment area of Eastern Sydney, Australia. The study was conducted in three stages: publicity building, case finding, and case validation. A brief structured questionnaire was sent to health professionals in the catchment area asking how many patients with YOD they had seen over the previous 12 months. Memory clinics and hospital records were also searched for YOD patients. Clinicians assigned a Statistical Linkage Key to each patient to prevent double counting, and indicated the cause of dementia. The majority of patients were validated by a review of medical case notes. Prevalence data were calculated for the following age groups: 30-64, 30-44, and 45-64 years. Two hundred and four potential patients were identified, of which 141 met inclusion criteria. The primary clinical subtypes were alcohol-related dementia (18.4%), Alzheimer's disease (17.7%), vascular dementia (12.8%), and frontotemporal dementia (11.3%). Eighty-eight patients were aged 30 to 64 years on census date and were therefore included in the prevalence calculations. The overall prevalence was 68.2 per 100,000 population at risk for the 30-64-year age group (95% Confidence Interval (CI): 54.9-83.4); 11.6 per 100,000 for the 30-44-year age group (95% CI: 5.3-21.7); and 132.9 per 100,000 for the 45-64 age group (95% CI: 105.8-164.2). Younger onset dementia affects a significant number of people in Eastern Sydney with a diverse range of clinical types. This prevalence rate is higher than previous reports from the United Kingdom and Japan, with a different distribution of etiologies, which have important implications for service planning for this group.

    The head circumference growth reference charts for children in China are presently based on urban children. However, the references may not apply to rural children because of the differences between urban and rural areas, such as economy, culture, and dietary habits. Our objective was to provide a reliable continuous set of head circumference growth reference charts for male and female children less than 7 years of age in Chinese rural areas. Children in our study were identified by multistage stratified cluster sampling from rural areas of 10 provinces in China. Questionnaire survey and anthropometric measurements were conducted in data collection. Head circumference was measured with a nonelastic tape on a line passing over the glabella and posterior occipital protrusion in children. We compared the fiftieth percentile of our cross-sectional data with the data of Chinese cities, World Health Organization, and the United States. A total of 95,904 children (48,722 boys and 47,182 girls) were included in the study. We present age- and sex-appropriate head circumference growth charts younger than 7 years for Chinese rural areas. The head circumference percentiles of the children in rural China are much smaller than the children in Chinese urban areas, World Health Organization, and the US percentiles after 2 years old. Head circumference percentiles can be applied in growth monitoring, but current head circumference growth references promulgated in urban China may not be suitable for rural areas in China. Providing head circumference growth reference charts for rural Chinese children who are younger than 7 years old is very important. Copyright © 2014 Elsevier Inc. All rights reserved.

    To explore the usefulness and accessibility of different delivery modes of disease-related education and support, as perceived by younger people with osteoarthritis (OA). People ages 20-55 years with hip or knee OA were recruited from 3 major Australian public hospitals and the community (n = 147). Data were collected on use of disease-related education and support services, as well as perceived usefulness and accessibility of delivery modes including group-based programs, online resources, telephone helplines, mailed information, social media, and mobile applications (rated on visual analog scales from 1-10; higher scores indicate greater usefulness or accessibility). Very few participants had used social media (5%), group self-management programs (3%), or telephone helplines (2%) to obtain OA information. Mailed information packs and online education programs were considered the most useful (median usefulness scores 8.0 and 7.0, respectively) and accessible methods (median accessibility scores 10.0 and 9.0, respectively) for providing OA education and support. Social media was perceived as least useful (median usefulness score 2.0) and least accessible; 45% of participants considered it "not at all useful," while 35% reported it would be "very difficult" to access OA education and support by this means. Less educational attainment was associated with greater perceived difficulty in accessing online/electronic delivery modes, while people in paid work perceived easier access. These data highlight the value of mailed information and online education to younger people with OA and can be used to develop targeted resources for individuals of working age. Social media was not a highly valued source of disease-related education and support. © 2016, American College of Rheumatology.

    Avoiding pedestrians is an integral part of our daily activities, yet this locomotor activity has received little attention in gait research. A recent study [Motor Control 2005;9:242] described the motor strategies used by young adults to circumvent an obstruction in different environmental contexts including obstacle movement, certainty about this obstacle movement and auditory distractions. The relationship between normal aging and such locomotor activity within these different environmental contexts, however, is not known. The purpose of this study was thus to compare the walking speed and the personal space-a protective zone preserved around the body-in healthy younger and older adults during obstacle circumvention in the above mentioned environmental contexts. The movements of nine younger adults (24.6+/-4.1 years) and nine older adults (69.7+/-3.2 years) were measured as they circumvented a stationary or moving mannequin with and without initial knowledge of the obstacle's displacements. Participants also had to pay attention to auditory messages, played in half of the trials, and to answer related questions. Results showed that all three environmental factors resulted in decreased gait speed in both groups, but the effect of auditory distractions was greater in older adults. Older adults also increased their personal space more than younger adults while paying attention to messages and they made more mistakes when answering related questions. Therefore, even if such an avoidance task is performed routinely, the increased information processing demanded by the environmental context affected both the motor and cognitive performance of older adults more than that of younger adults.

    Concentrations of tenofovir (TFV) in hair and tenofovir diphosphate (TFV-DP) in dried blood spots (DBSs) as measures of cumulative exposure have been primarily studied in younger, HIV-uninfected individuals taking preexposure HIV prophylaxis. Data on these measures among older HIV-infected individuals are limited. We evaluated longitudinal TFV and TFV-DP concentrations in hair and DBS, respectively, from HIV-infected adults. Multivariable model variables included age group (18-35 and 60 years and older), creatinine clearance (CrCl), hematocrit (TFV-DP), and gray hair color (TFV). Baseline hair TFV and DBS TFV-DP were moderately correlated [r = 0.5 (0.2 to 0.7); P = 0.001] across both age groups [younger (N = 23) and older (N = 22)]. In adjusted models, CrCl was associated with increases of 15.9% (7.4% to 25.0%); P = 0.0006, and 5.7% (-0.2% to 11.9%); P = 0.057 for TFV in hair and TFV-DP in DBS, respectively, for every 20-mL/min CrCl decrease. Although older age (versus younger age) was univariately associated with increased TFV hair levels, older age was not significantly associated with higher concentrations in hair [-1.4% (-26.7% to 32.7%); P = 0.93] or DBS [4.0% (-14.1% to 25.9%); P = 0.68] after adjustment. Similarly, gray color was not significantly associated with higher TFV levels in hair [27.6% (-11.1% to 83.0%; P = 0.18)] in adjusted models. In both adjusted and unadjusted models of TFV-DP levels in DBS, a 1% hematocrit increase was associated with a 3.3% (0.2% to 6.5%) TFV-DP increase (P = 0.04). Cumulative drug exposure measures (hair and DBS) were comparable in younger and older HIV-infected individuals on TFV-based therapy after adjustment for renal function.

    Total ankle arthroplasty (TAA) is becoming an increasingly utilized procedure for the management of end-stage ankle arthritis. Elderly patients are the fastest growing segment of the population in the western world, creating a unique challenge to the health economics of our era. Determining if elderly patients with end-stage ankle arthritis demonstrate the same improvements in clinical outcomes and functional measures of gait following TAA would be valuable. This can aid to evaluate the utilization of TAA in this enlarging cohort of our population. Consecutive series of twenty-one patients over the age of 70, who underwent TAA for end-stage ankle arthritis, was prospectively compared to a series of twenty-one patients aged 50-60, who underwent the same procedure by single surgeon during same time period. Clinical outcomes were measured with outcome scores including VAS pain score, AOFAS Ankle and Hindfoot Score, and the SF-36. Three-dimensional gait analysis was performed preoperatively and at a minimum of one year postoperatively, to measure temporal-spatial, kinematic, and kinetic parameters of gait. Mixed model multivariate statistical analysis was used to evaluate and compare the independent contributions to outcomes of the surgical intervention over time; of patient age; and of time-plus-age interaction, as these influenced both the clinical outcomes and the functional gait outcomes. Statistically significant improvements in VAS pain scores, AOFAS ankle/hindfoot scores, and SF-36 scores were demonstrated in both age groups. Following surgery, there were improvements in all parameters of gait, including temporal-spatial parameters as step length and walking velocity; kinematic parameters, including, increase in total range of motion to a total of 17-19°; and kinetic parameters, including increase in ankle power and moment. The improvements both in clinical and gait outcomes were equivalent in the two age groups. In this comparative study, it is shown that both

    To compare the demographic characteristics and intra- and postoperative outcomes in elderly adults (≥75) with those of younger adults undergoing early (cholecystitis (ACC) according to the Tokyo Guidelines (N=414; n=78 aged 75-94, median 82; n=336 aged 18-74, median 49). Demographic characteristics and pre-, intra-, and postoperative data. The elderly group was more likely to have an American Society of Anesthesiologists score of 3 or greater (62% vs 23%, Pcholecystitis (38% vs 15%, P=.001)) on preoperative imaging and confirmed intraoperatively. Ulcerated mucosa (76% vs 61%, P=.001) was significantly more frequent in the elderly group. Operative time, postoperative mortality, and postoperative infectious (18% vs 14%, P=.35) and noninfectious (9% vs 3%, P=.80) complications were similar between the two groups. Median length of stay (7.0 vs 5.0 days, P=.54) and readmission rate (15% vs 4%, P=.07) were not significantly higher in the elderly group. No significant difference was observed for the subgroup of participants aged 80 and older. In this randomized trial that included a selected sample of older adults, there was no difference in major outcomes between elderly adults and their younger counterparts after early cholecystectomy. The findings are limited because important geriatric outcomes such as delirium and functional decline were not examined. © 2015, Copyright the Authors Journal compilation © 2015, The American Geriatrics Society.

    The hypothesis that exposure to ionizing radiation accelerates the aging process has been actively investigated at ABCC-RERF since 1958, when longitudinal cohort studies of the Adult Health Study (AHS) and the Life Span Study (LSS) were initiated. In their 1975 overall review of aging studies related to the atomic bomb (A-bomb) survivors, Finch and Beebe concluded that while most studies had shown no correlation between aging and radiation exposure, they had not involved the large numbers of subjects required to provide strong evidence for or against the hypothesis. Extending LSS mortality data up to 1978 did not alter the earlier conclusion that any observed life-shortening was associated primarily with cancer induction rather than with any nonspecific cause. The results of aging studies conducted during the intervening 15 years using data from the same populations are reviewed in the present paper. Using clinical, epidemiological, and laboratory techniques, a broad spectrum of aging parameters have been studied, such as postmortem morphological changes, tests of functional capacity, physical tests and measurements, laboratory tests, tissue changes, and morbidity. With respect to the aging process, the overall results have not been consistent and are generally thought to show no relation to radiation exposure. Although some preliminary results suggest a possible radiation-induced increase in atherosclerotic diseases and acceleration of aging in the T-cell-related immune system, further study is necessary to confirm these findings. In the future, applying the latest gerontological study techniques to data collected from subjects exposed 45 years ago to A-bomb radiation at relatively young ages will present a new body of data relevant to the study of late radiation effects.

    To study how comprehension of cardiovascular disease (CVD) risk is influenced by: (1) infographics about qualitative risk information, with/without risk numbers; (2) which qualitative risk dimension is emphasized; (3) heart age vs. traditional risk format. For aim 1, a 2 (infographics versus text) x 2 (risk number versus no risk number) between-subjects design was used. For aim 2, three pieces of information were tested within-subjects. Aim 3 used a simple comparison group. Participants (45-65 yrs old) were recruited through an online access panel; low educated people were oversampled. They received hypothetical risk information (20%/61yrs). Primary outcomes: recall, risk appraisals, subjective/objective risk comprehension. behavioral intentions, information evaluations. Infographics of qualitative risk dimensions negatively affected recall, subjective risk comprehension and information evaluations. No effect of type of risk dimension was found on risk perception. Heart age influenced recall, comprehension, evaluations and affective risk appraisals. Infographics of hypothetical CVD risk information had detrimental effects on measures related to risk perception/comprehension, but effects were mainly seen in undereducated participants. Heart age influenced perceptions/comprehension of hypothetical risk in a way that seemed to support understanding. Heart age seems a fruitful risk communication approach in disease risk calculators.

    The final stage of dental development of third molars is usually helpful to indicate whether or not a subject is aged over 18 years. A complexity is that the final stage of development is unlimited in its upper border. Investigators usually select an inappropriate upper age limit or censor point for this tooth development stage. The literature was searched for appropriate data sets for dental age estimation and those that provided the count (n), the mean (x¯), and the standard deviation (sd) for each of the tooth development stages. The Demirjian G and Demirjian H were used for this study. Upper and lower limits of the Stage G and Stage H data were calculated limiting the data to plus or minus three standard deviations from the mean. The upper border of Stage H was limited by appropriate censoring at the maximum value for Stage G. The maximum age at attainment from published data, for Stage H, ranged from 22.60 years to 34.50 years. These data were explored to demonstrate how censoring provides an estimate for the correct maximum age for the final stage of Stage H as 21.64 years for UK Caucasians. This study shows that confining the data array of individual tooth developments stages to ± 3sd provides a reliable and logical way of censoring the data for tooth development stages with a Normal distribution of data. For Stage H this is inappropriate as it is unbounded in its upper limit. The use of a censored data array for Stage H using Percentile values is appropriate. This increases the reliability of using third molar Stage H alone to determine whether or not an individual is over 18 years old. For Stage H, individual ancestral groups should be censored using the same technique. Copyright © 2015 Elsevier Ltd and Faculty of Forensic and Legal Medicine. All rights reserved.

    The incidence of epilepsy is high in older individuals. However, epilepsy in the elderly may be underdiagnosed and undertreated because of diagnostic difficulties. The main goal of this study was to determine whether seizure semiology differs between older and younger adults with epilepsy in the outpatient setting. Fifty patients with focal epilepsy aged 55 years and older and 50 patients aged between 18 and 45 years were included. Review of medical records contained detailed seizure description. There were no differences in seizure semiology between groups, except that subtle perceptions of transient confusion were seen in older patients but not in younger patients (P=0.0028). Older patients had less generalized motor seizures, but the differences between groups did not reach significance (P=0.01). Older patients may present with subtle symptoms of seizures characterized by brief periods of confusion, which may contribute to greater difficulty diagnosing seizures in the elderly.

    The memorial costs and benefits of trial-and-error learning have clear pedagogical implications for students, and increasing evidence shows that generating errors during episodic learning can improve memory among younger adults. Conversely, the aging literature has found that errors impair memory among healthy older adults and has advocated for…

  19. Body Image in Adult Women: Moving Beyond the Younger Years

    2015-01-01

    In spite of copious literature investigating body dissatisfaction and its correlates in adolescents and young adult women, exploration of body image disturbances in adult women remains an underrepresented domain in the literature. Yet, there are many reasons to suspect that body image in adult women both may differ from and possibly be more complex than that of younger women. Adult women face myriad factors influencing body image beyond those delineated in the body image literature on adolescents and young adult women. For instance, aging-related physiological changes shift the female body further away from the thin-young-ideal, which is the societal standard of female beauty. Further, life priorities and psychological factors evolve with age as well. As such, adult women encounter changes that may differentially affect body image across the lifespan. This paper aims to provide an up-to-date review of the current literature on the relationship between body image and associated mental and physical health problems and behaviors in adult women. In addition, we explore factors that may influence body image in adult women. Lastly, we use this review to identify significant gaps in the existing literature with the aim of identifying critical targets for future research. PMID:26052476

    Chronic mucus hypersecretion (CMH) is a common condition in patients with chronic respiratory diseases. Little is known about the incidence, prevalence and determinants of CMH in younger individuals. To determine prevalence, incidence and risk factors for CMH in a young general population. A cohort of Danish twins (aged 12-41 years) was prospectively examined using questionnaires in 1994 (n = 29 180) and in 2002 (n = 21 130). Prevalence and incidence of CMH were determined, and risk factors for the condition were assessed using logistic regression. Lifetime prevalence of CMH was 8.6% in females and 6.9% in males in 1994, and the cumulative incidence among females and males was respectively 10.7% and 8.7% during the study period. Smoking and asthma were risk factors for CMH, with a dose-response effect of tobacco consumption, and smoking habits also predicting incidence of CMH. Among the young, CMH is a condition related to asthma and smoking, with a dose-response relationship with tobacco consumption and a relation between smoking habits and incidence. Female susceptibility to development of CMH was observed, as well as signs of greater susceptibility related to young age.

  1. Atmospheric 14C variations derived from tree rings during the early Younger Dryas

    Atmospheric radiocarbon variations over the Younger Dryas interval, from ˜13,000 to 11,600 cal yr BP, are of immense scientific interest because they reveal crucial information about the linkages between climate, ocean circulation and the carbon cycle. However, no direct and reliable atmospheric 14C records based on tree rings for the entire Younger Dryas have been available. In this paper, we present (1) high-precision 14C measurements on the extension of absolute tree-ring chronology from 12,400 to 12,560 cal yr BP and (2) high-precision, high-resolution atmospheric 14C record derived from a 617-yr-long tree-ring chronology of Huon pine from Tasmania, Australia, spanning the early Younger Dryas. The new tree-ring 14C records bridge the current gap in European tree-ring radiocarbon chronologies during the early Younger Dryas, linking the floating Lateglacial Pine record to the absolute tree-ring timescale. A continuous and reliable atmospheric 14C record for the past 14,000 cal yr BP including the Younger Dryas is now available. The new records indicate that the abrupt rise in atmospheric Δ 14C associated with the Younger Dryas onset occurs at ˜12,760 cal yr BP, ˜240 yrs later than that recorded in Cariaco varves, with a smaller magnitude of ˜40‰ followed by several centennial Δ 14C variations of 20-25‰. Comparing the tree-ring Δ 14C to marine-derived Δ 14C and modelled Δ 14C based on ice-core 10Be fluxes, we conclude that changes in ocean circulation were mainly responsible for the Younger Dryas onset, while a combination of changes in ocean circulation and 14C production rate were responsible for atmospheric Δ 14C variations for the remainder of the Younger Dryas.

    This study investigated attributions of autonomy and competence. Respondents completed items following one of four vignettes in which a character was identified as an older male, younger male, older female, or younger female with a history of hallucinations, substance abuse, and living on the street. Respondents viewed the vignette character as suffering from malnutrition, alcoholism, depression, and likely to commit suicide. A General Linear Model revealed harsher perceptions toward the older vignette characters. When controlling for educational exposure to aging and psychopathology, there were significant differences in eight of 37 items (F = 116.270, df = 37, p < .001).

    2014-01-01

    Verbal play, or the playful manipulation of elements of language, is a pervasive component of social interaction, serving important interpersonal functions. We analyzed verbal play in the interactional discourse of ten healthy younger pairs and ten healthy older pairs as they completed a collaborative referencing task. A total of 1,893 verbal play episodes were coded. While there were no group differences in verbal play frequency, age-related differences in the quality and function of these episodes emerged. While older participants engaged in more complex, extended, and reciprocal episodes that supported the social nature of communicative interactions (e.g., teasing), younger participants were more likely to engage in verbal play episodes for the purpose of successful task completion. Despite these age-related variations in the deployment of verbal play, verbal play is a robust interactional discourse resource in healthy aging, highlighting an element of human cognition that does not appear to decline with age.

    HIV-infected pregnant women in sub-Saharan Africa are at risk for depression and alcohol abuse. Young women may be more vulnerable, but little is known about the psychosocial functioning of this population. We compared younger (18-24 years old) and older (≥25 years old) HIV-infected pregnant women initiating antiretroviral therapy (ART) in Cape Town, South Africa. Women were assessed on a range of psychosocial measures, including the Alcohol Use Disorders Identification Test and the Edinburgh Postnatal Depression Scale (EPDS). Among 625 women initiating ART, 16 % reported risky alcohol use and 21 % alcohol-related harm; these percentages were similar across age groups. When younger women were stratified by age, 37 % of 18-21 years old versus 20 % of 22-24 years old reported alcohol-related harm (p = 0.02). Overall, 11 % of women had EPDS scores suggesting probable depression, and 6 % reported self-harming thoughts. Younger women reported more depressive symptoms. Report of self-harming thoughts was 11 % in younger and 4 % in older women (p = 0.002). In multivariable analysis, age remained significantly associated with depressive symptoms and report of self-harming thoughts. Level of HIV-related stigma and report of intimate partner violence modified the association between age and depressive symptoms. Young HIV-infected pregnant women in South Africa were more likely to report depressive symptoms and self-harming thoughts compared to older women, and the youngest women reported the highest levels of alcohol-related harm. HIV-related stigma and intimate partner violence may be moderating factors. These findings have implications for maternal and infant health, underscoring the urgent need for effective targeted interventions in this vulnerable population.

    Involuntary episodic memories are memories of past events that come to mind with no preceding attempt of retrieval. Such memories have received little attention in relation to aging compared with voluntary episodic memories (i.e., intentionally retrieved memories of past events). It is well documented that older compared with younger adults have reduced access to episodic memories, when retrieval is voluntary, but little is known about their involuntary episodic recall. Recent evidence suggests that involuntary autobiographical memories are at least as frequent as voluntary autobiographical memories in daily life, but this research has been limited to younger adults. Here older and younger adults recorded involuntary and voluntary episodic memories in relation to a film of a simulated event (Study 1) and during a normal day in their lives (Study 2). Across both studies, no age differences were found regarding the frequency of involuntary episodic memories, whereas older adults showed slower (Study 1) and less frequent (Study 2) voluntary remembering compared with younger adults. The findings suggest that involuntary relative to voluntary episodic remembering is enhanced in older adults, consistent with reduced executive functioning and increased processing of task irrelevant information with aging. Involuntary episodic remembering may provide an adaptive compensation for reductions in strategic retrieval in later adulthood. (PsycINFO Database Record (c) 2017 APA, all rights reserved).

  11. Writing in a Digital World: Self-Correction While Typing in Younger and Older Adults

    Full Text Available This study examined how younger and older adults approach simple and complex computerized writing tasks. Nineteen younger adults (age range 21–31, mean age 26.1 and 19 older adults (age range 65–83, mean age 72.1 participated in the study. Typing speed, quantitative measures of outcome and process, and self-corrections were recorded. Younger adults spent a lower share of their time on actual typing, and demonstrated more prevalent use of delete keys than did older adults. Within the older group, there was no correlation between the total time spent on the entire task and the number of corrections, but increased typing speed was related to more errors. The results suggest that the approach to the task was different across age groups, either because of age or because of cohort effects. We discuss the interplay of speed and accuracy with regard to digital writing, and its implications for the design of human-computer interactions.

    This study evaluated defense mechanism differences between younger and older adults and also assessed the relationship between defense mechanisms and perceived stress, in order to provide evidence of construct validity of a self-reported defense mechanisms scale. Community-dwelling younger (n = 259; M age = 19.7 years) and older adults (n = 69; M age = 70.8 years) completed the Defense Style Questionnaire and the Perceived Stress Scale. Whereas there were no age differences on adaptive defense mechanisms, younger adults scored higher than older adults on the Acting Out, Passive-Aggression, and Regression maladaptive defense mechanism scales. Maladaptive defenses were significantly and positively correlated (r = .57) with perceived stress. Cross-sectional results suggest a general stability of adaptive defense mechanisms across the lifespan but a lessening of maladaptive defense mechanisms with advancing age. These results dispel the myth that old age is associated with inevitable psychological impairment and suggest some specific positive psychological adaptations with age. The correlational findings provide partial support for the construct validity of a self-report measure of defense mechanisms.

    Sensitivity to motion direction is affected by stimulus size, contrast (D. Tadin & J. S. Lappin, 2005; D. Tadin, J. S. Lappin, L. A. Gilroy, & R. Blake, 2003), and observer age (L. R. Betts, C. P. Taylor, A. B. Sekuler, & P. J. Bennett, 2005). Here, we investigated the effect of spatial frequency on motion discrimination and how sensitivity changes in older adulthood. We measured stimulus duration thresholds for younger (18-30 years) and older (60-75 years) observers using drifting Gabor gratings that differed in size, spatial frequency, and contrast. A simple model characterized age differences in the threshold-vs.-size functions. The model parameter fits were consistent with an age-related decrease in the strength of spatial suppression. The model also provided good fits to the thresholds when plotted as a function of the total stimulus contrast energy, which suggests that age-related changes in summation and suppression can be modeled as reduced sensitivity to contrast energy. The summation parameter scaled according to stimulus spatial frequency in younger observers only. Suppression strength decreased as a function of spatial frequency in both age groups. Our findings provide additional evidence for age-related changes in summation and suppression mechanisms and suggest that the total contrast energy in the stimulus plays an important role in determining sensitivity to motion direction in both younger and older adults.

    Full Text Available Ageing is associated with a general reduction of physiological function and a reduction of muscle mass and strength. Endocrine factors such as myostatin, activin A, growth and differentiation factor 11 (GDF-11 and their inhibitory peptides influence muscle mass in health and disease. We hypothesised that myocytes cultured in plasma from older and younger individuals would show an ageing effect, with reduced proliferation and differentiation in older environments. C2C12 myoblasts were grown as standard and stimulated with media conditioned with 5% plasma from healthy male participants that were either younger (n = 6, 18–35 years of age or older (n = 6, >57 years of age. Concentration of plasma myostatin (total and free, follistatin-like binding protein (FLRG, GDF-11 and activin A were quantified by ELISA. Both FLRG and activin A were elevated in older individuals (109.6 and 35.1% increase, respectively, whilst myostatin (free and total and GDF-11 were not. Results indicated that plasma activin A and FLRG were increased in older vs. younger participants, GDF11 and myostatin did not differ. Myoblasts in vitro showed no difference in proliferation rate between ages, however scratch closure was greater in younger vs. older plasma stimulated myoblasts (78.2 vs. 87.2% of baseline scratch diameter, respectively. Myotube diameters were larger in cells stimulated with younger plasma than with older at 24 and 48 h, but not at 2 h. A significant negative correlation was noted between in vivo plasma FLRG concentration and in vitro myotube diameter 48 h following plasma stimulation (r2 = 0.392, p = 0.030. Here we show that myoblasts and myotubes cultured in media conditioned with plasma from younger or older individuals show an ageing effect, and further this effect moderately correlates with circulating FLRG concentration in vivo. The effect of ageing on muscle function may not be innate to the tissue, but involve a general cellular environment change

    Full Text Available The aim of this research is to determine whether there is any statistically signifi cant diff erence in motor abilities of boys and girls of younger school age. The sample includes 76 examinees with 37 males and 39 females. All are 5th and 6 th graders of primary school. The evaluation of motor abilitied is based on 5 tests. Multivariant analysis of variance is applied for determination of diff erences within the whole system of motor tests, whereas univariant analysis of variance is used for determining diff erences in each motor test. According to the fi ndings, statistically signifi cant diff erences in motor abilities between boys and girls at the studied age can be noticed in the test 20 m running from fl ying start, which is in favour of boys and in the test sit and reach, in favour of girls, while the diff erences in other tests are not statistically signifi cant. Considering the evaluation of motor abilities, boys have statistically much better results in the speed of alternative movements and explosive strenth, whereas girls have achieved much better results in the test for fl exibility. It has also been concluded that 5th and 6th graders have statistically better results in the space of coordination and explosive strenght, whereas girls are much better in the fi eld of fl exibility and suppleness.

    This study analyzed child feeding beliefs and behaviors, types of recipes, and their associations in blogs focused on child feeding. The authors selected 13 blogs using purposive snowball sampling, from which 158 blog posts were sampled and coded using directed qualitative content analysis. Child feeding beliefs and behaviors and types of recipes were coded using schemes developed from existing literature. Code frequencies were calculated. Chi-square tests for independence examined associations between child feeding and recipe codes. Bonferroni corrections were applied: P feeding beliefs and behaviors were coded in 78% and 49% of posts, respectively. Beliefs about children's food preferences (48% of posts) and involving children in food preparation (27% of posts) were the most frequent codes. Recipes were included in 66% of posts. Most recipes were for mixed dishes (32% of recipes), followed by sweets and desserts (19% of recipes). Vegetable recipes were more likely in posts that included behavior encouraging balance and variety (χ2 [1, n = 104] = 18.54; P feeding practices. Future research should explore how mothers use blogs to learn about child feeding. Copyright © 2016 Society for Nutrition Education and Behavior. Published by Elsevier Inc. All rights reserved.

    Few studies have compared outcomes after meniscus suture repair in patients younger than 40 years versus patients 40 years and older. To document failure rates and long-term outcomes after meniscus suture repair by a single surgeon, using the inside-out technique, at a minimum 10-year follow-up in patients younger than 40 years versus those 40 years and older. Cohort study; Level of evidence, 3. This study included all patients 18 years or older who underwent meniscus suture repair with the inside-out technique by a single surgeon between January 1992 and December 2003. Patients were divided into 2 cohorts according to age: meniscus as repaired in the index surgery. Patients completed a subjective questionnaire at minimum of 10 years after arthroscopy. Outcomes measures included Lysholm, Tegner, and patient satisfaction with outcome. All data were collected prospectively. The surgeon performed 339 meniscus repairs between 1992 and 2003. The study included 181 knees in 178 patients, who had a mean age of 33 years (range, 18-70 years). Cohort 1 contained 136 knees; 16 patients (12%) were lost to follow-up and 47 (35%) underwent a subsequent knee arthroscopy. Cohort 2 contained 45 knees; 2 patients (4.4%) were lost to follow-up, 3 patients had a total knee arthroplasty, and 12 patients (28%) underwent a subsequent knee arthroscopy. In cohort 1, the meniscus repair failure rate was 5.5% (6/110), and in cohort 2 it was 5.3% (2/38) (P = .927). There was no significant difference in failure rate based on which meniscus was repaired (P = .257), concomitant anterior cruciate ligament (ACL) reconstruction (P = .092), or microfracture (P = .674). Average follow-up time for cohort 1 was 16.1 years (range, 10.0-21.9 years), with 82% follow-up (n = 73/89); average follow-up time for cohort 2 was 16.2 years (range, 10.1-21.0 years), with 93% follow-up (n = 28/30). There were no significant differences in outcomes scores after meniscus suture repair based on age cohort or meniscus

    Acquisition of numerical knowledge and understanding of numerical information are crucial for coping with the changing demands of our digital society. In this study, we assessed arithmetic learning in older and younger individuals in a training experiment including brain imaging. In particular, we assessed age-related effects of training intensity, prior arithmetic competence, and neuropsychological variables on the acquisition of new arithmetic knowledge and on the transfer to new, unknown problems. Effects were assessed immediately after training and after 3 months. Behavioural results showed higher training effects for younger individuals than for older individuals and significantly better performance after 90 problem repetitions than after 30 repetitions in both age groups. A correlation analysis indicated that older adults with lower memory and executive functions at baseline could profit more from intensive training. Similarly, training effects in the younger group were higher for those individuals who had lower arithmetic competence and executive functions prior to intervention. In younger adults, successful transfer was associated with higher executive functions. Memory and set-shifting emerged as significant predictors of training effects in the older group. For the younger group, prior arithmetic competence was a significant predictor of training effects, while cognitive flexibility was a predictor of transfer effects. After training, a subgroup of participants underwent an MRI assessment. A voxel-based morphometry analysis showed a significant interaction between training effects and grey matter volume of the right middle temporal gyrus extending to the angular gyrus for the younger group relative to the older group. The reverse contrast (older group vs. younger group) did not yield any significant results. These results suggest that improvements in arithmetic competence are supported by temporo-parietal areas in the right hemisphere in younger

    This study compared the effect of acute caffeine ingestion on coincidence timing accuracy in younger and older adults. Thirteen young (aged 18-25 years, age: 20 ± 2 years, 7 females, 5 males) and 13 older (aged 61-77 years, age: 68 ± 6 years, 9 females, 3 males) adults, all who were habitual moderate caffeine consumers undertook measures of coincident anticipation timing performance pre- and post-acute caffeine (3 mg/kg) or placebo ingestion administered in a double blind, randomized fashion. Results indicated significant pre-to-post X substance (caffeine vs. placebo) interactions for absolute (P = 0.02, Pη(2) = 0.204) and variable error (P = 0.015, Pη(2) = 0.221). In both cases, error (absolute or variable) improved pre-to-post ingestion in the caffeine condition but not in the placebo condition. There were no significant differences due to age (younger vs. older adults, P > 0.05) in any of the analyses. The results of this study suggest that acute caffeine ingestion positively influence coincidence anticipation timing performance in both younger and older adults, who are moderate habitual caffeine consumers. Such effects might therefore be useful for older adults in enhancing ability to undertake cognitive-perceptual tasks which involve interceptive actions.

    Valuable items are often remembered better than items that are less valuable by both older and younger adults, but older adults typically show deficits in binding. Here, we examine whether value affects the quality of recognition memory and the binding of incidental details to valuable items. In Experiment 1, participants learned English words each associated with a point-value they earned for correct recognition with the goal of maximizing their score. In Experiment 2, value was manipulated by presenting items that were either congruent or incongruent with an imagined state of physiological need (e.g., hunger). In Experiment 1, point-value was associated with enhanced recollection in both age groups. Memory for the color associated with the word was in fact reduced for high-value recollected items compared with low-value recollected items, suggesting value selectively enhances binding of task-relevant details. In Experiment 2, memory for learned images was enhanced by value in both age groups. However, value differentially enhanced binding of an imagined context to the item in younger and older adults, with a strong trend for increased binding in younger adults only. These findings suggest that value enhances episodic encoding in both older and younger adults but that binding of associated details may be reduced for valuable items compared to less valuable items, particularly in older adults.

  1. Expressive Suppression and Enhancement During Music-Elicited Emotions in Younger and Older Adults

    Directory of Open Access Journals (Sweden)

    2015-02-01

    Full Text Available When presented with emotional visual scenes, older adults have been found to be equally capable to regulate emotion expression as younger adults, corroborating the view that emotion regulation skills are maintained or even improved in later adulthood. However, the possibility that gaze direction might help achieve an emotion control goal has not been taken into account, raising the question whether the effortful processing of expressive regulation is really spared from the general age-related decline. Since it does not allow perceptual attention to be redirected away from the emotional source, music provides a useful way to address this question. In the present study, affective, behavioral and physiological consequences of free expression of emotion, expressive suppression and expressive enhancement were measured in 31 younger and 30 older adults while they listened to positive and negative musical excerpts. The main results indicated that compared to younger adults, older adults reported experiencing less emotional intensity in response to negative music during the free expression of emotion condition. No age difference was found in the ability to amplify or reduce emotional expressions. However, an age-related decline in the ability to reduce the intensity of emotional state and an age-related increase in physiological reactivity were found when participants were instructed to suppress negative expression. Taken together, the current data support previous findings suggesting an age-related change in response to music. They also corroborate the observation that older adults are as efficient as younger adults at controlling behavioral expression. But most importantly, they suggest that when faced with auditory sources of negative emotion, older age does not always confer a better ability to regulate emotions.

    When presented with emotional visual scenes, older adults have been found to be equally capable to regulate emotion expression as younger adults, corroborating the view that emotion regulation skills are maintained or even improved in later adulthood. However, the possibility that gaze direction might help achieve an emotion control goal has not been taken into account, raising the question whether the effortful processing of expressive regulation is really spared from the general age-related decline. Since it does not allow perceptual attention to be redirected away from the emotional source, music provides a useful way to address this question. In the present study, affective, behavioral, and physiological consequences of free expression of emotion, expressive suppression and expressive enhancement were measured in 31 younger and 30 older adults while they listened to positive and negative musical excerpts.

    Despite the fundamental role of category learning in cognition, few studies have examined how this ability differs between younger and older adults. The present experiment examined possible age differences in category learning strategies and their effects on learning. Participants were trained on a category determined by a disjunctive rule applied to relational features. The utilization of rule- and exemplar-based strategies was indexed by self-reports and transfer performance. Based on self-reported strategies, the frequencies of rule- and exemplar-based learners were not significantly different between age groups, but there was a significantly higher frequency of intermediate learners (i.e., learners not identifying with a reliance on either rule- or exemplar-based strategies) in the older than younger adult group. Training performance was higher for younger than older adults regardless of the strategy utilized, showing that older adults were impaired in their ability to learn the correct rule or to remember exemplar-label associations. Transfer performance converged with strategy reports in showing higher fidelity category representations for younger adults. Younger adults with high working memory capacity were more likely to use an exemplar-based strategy, and older adults with high working memory capacity showed better training performance. Age groups did not differ in their self-reported memory beliefs, and these beliefs did not predict training strategies or performance. Overall, the present results contradict earlier findings that older adults prefer rule- to exemplar-based learning strategies, presumably to compensate for memory deficits.

    Full Text Available Differences in inhibitory ability between older (64-79 years, N=24 and younger adults (18-26 years, N =24 were investigated using a diffusion model analysis. Participants performed a task-switching paradigm that allows assessing n-2 task repetition costs, reflecting inhibitory control on the level of tasks, as well as n-1 response-repetition costs, reflecting inhibitory control on the level of responses. N-2 task repetition costs were of similar size in both age groups. Diffusion model analysis revealed that for both younger and older adults, drift rate parameters were smaller in the inhibition condition relative to the control condition, consistent with the idea that persisting task inhibition slows down response selection. Moreover, there was preliminary evidence for task inhibition effects in threshold separation and non-decision time in the older, but not the younger adults, suggesting that older adults might apply different strategies when dealing with persisting task inhibition. N-1 response-repetition costs in mean RT tended to be larger in older than younger adults, but in mean error rates were larger in younger than older adults. Diffusion-model analysis revealed longer non-decision times in response repetitions than response switches in both age groups, consistent with the idea that motor processes take longer in response repetitions than response switches due to persisting response inhibition of a previously executed response. The data also revealed age-related differences in overall performance: Older adults responded more slowly and more accurately than young adults, which was reflected by a higher threshold separation parameter in diffusion model analysis. Moreover, older adults showed larger non-decision times and higher variability in non-decision time than young adults, possibly reflecting slower and more variable motor processes. In contrast, overall drift rate did not differ between older and younger adults. Taken together

    Age differences are not evident in pain-related stoicism and cautiousness in people with cancer pain. Little is known about the factors associated with these pain-related attitudes or age-related patterns in these associations. The present cross-sectional study investigated the biopsychosocial correlates of the attitudes in younger and older patients with advanced cancer. Pain-related stoicism (fortitude, concealment, superiority) and cautiousness (self-doubt, reluctance) were assessed using the Pain Attitudes Questionnaire-Revised (PAQ-R). Participants, 155 younger (younger than 60 years old) and 114 older (60 years old or older) patients with advanced cancer completed the PAQ-R and measures of sociodemographic and medical characteristics, pain intensity, cognitive-affective pain-related responses, physical functioning, psychological distress and well-being, and psychosocial functioning. Backwards regression analyses identified correlates for each PAQ-R factor separately for younger and older patients. Activity engagement was a frequent correlate, but its relationship with concealment was the only association common to both age groups. Younger and older patients exhibited different avoidance-related constructs suggesting relational challenges in the former group (avoidant attachment) and intrapersonal fear in the latter (cognitive avoidance). Medical correlates also showed age differences: younger patients showed symptom-focused correlates, whereas older patients showed aging-related correlates. Findings support a biopsychosocial framework of cancer-pain adaptation incorporating a lifespan-developmental perspective. To our knowledge, this article is the first to identify biopsychosocial correlates of stoic and cautious attitudes toward cancer pain in younger and older patients with advanced cancer. Findings highlight possible age-related motivations for greater pain-related stoicism or cautiousness and can potentially inform interventions addressing challenges in

    Older liver grafts have been considered in the past decade due to organ shortage. The aim was to compare outcomes after liver transplantation with either younger or older donors. Patients transplanted in our center between 2004 and 2014 with younger donors (younger than 60 years; n = 253) were compared with older donors (older than 75 years; n = 157). Multiorgan transplantations, split grafts, or non-heart-beating donors were not included. Donors in the older group were mostly women deceased from stroke, and only 3 patients had experienced cardiac arrest. Liver tests were significantly better in the older group than in the younger group. There was no difference regarding cold ischemia time, model for end-stage liver disease score, and steatosis. There was no significant difference regarding primary nonfunction and dysfunction, hepatic artery and biliary complications, and retransplantation rates. Graft survival was not different (65% and 64% in the older and younger groups, P = 0.692). Within the older group, hepatitis C infection, retransplantation, and emergency transplantation were associated with poor graft survival. Provided normal liver tests and the absence of cardiac arrest in donors, older liver grafts (>75 years) may be safely attributed to non-hepatitis C-infected recipients in the setting of a first and nonurgent transplantation.

    The controversial Younger Dryas impact hypothesis suggests that at the onset of the Younger Dryas an extraterrestrial impact over North America caused a global catastrophe. The main evidence for this impact--after the other markers proved to be neither reproducible nor consistent with an impact--is the alleged occurrence of several nanodiamond polymorphs, including the proposed presence of lonsdaleite, a shock polymorph of diamond. We examined the Usselo soil horizon at Geldrop-Aalsterhut (The Netherlands), which formed during the Allerød/Early Younger Dryas and would have captured such impact material. Our accelerator mass spectrometry radiocarbon dates of 14 individual charcoal particles are internally consistent and show that wildfires occurred well after the proposed impact. In addition we present evidence for the occurrence of cubic diamond in glass-like carbon. No lonsdaleite was found. The relation of the cubic nanodiamonds to glass-like carbon, which is produced during wildfires, suggests that these nanodiamonds might have formed after, rather than at the onset of, the Younger Dryas. Our analysis thus provides no support for the Younger Dryas impact hypothesis.

    We report two cases of subchondral insufficiency fracture of the femoral head observed in younger adults without any history of overexertion. In both cases, MRI revealed an irregular, discontinuous low-intensity band on the T1-weighted images. Both patients were treated operatively, and histological examination confirmed the diagnosis of subchondral fracture. A diagnosis of subchondral insufficiency fracture needs to be put in as one of the diagnoses in younger patients with a hip pain. (orig.)

    Full Text Available Obesity is associated with increased mortality and accelerated decline in kidney function in the general population. Little is known about the effect of obesity in younger and older pre-dialysis patients. The aim of this study was to assess the extent to which obesity is a risk factor for death or progression to dialysis in younger and older patients on specialized pre-dialysis care.In a multicenter Dutch cohort study, 492 incident pre-dialysis patients (>18y were included between 2004-2011 and followed until start of dialysis, death or October 2016. We grouped patients into four categories of baseline body mass index (BMI: <20, 20-24 (reference, 25-29, and ≥30 (obesity kg/m2 and stratified patients into two age categories (<65y or ≥65y.The study population comprised 212 patients younger than 65 years and 280 patients 65 years and older; crude cumulative risk of dialysis and mortality at the end of follow-up were 66% and 4% for patients <65y and 64% and 14%, respectively, for patients ≥65y. Among the <65y patients, the age-sex standardized combined outcome rate was 2.3 times higher in obese than those with normal BMI, corresponding to an excess rate of 35 events/100 patient-years. After multivariable adjustment the hazard ratios (HR (95% CI for the combined endpoint by category of increasing BMI were, for patients <65y, 0.92 (0.41-2.09, 1 (reference, 1.76 (1.16-2.68, and 1.81 (1.17-2.81.

    Photography is a tool that has been used in research for many years. It allows people to create a record of an event, capture a complex phenomenon or to tell a story with pictures. Because it does not rely on language, it can be used with vulnerable populations who might not normally be included in research. This paper discusses the use of photography as one component of the evaluation strategy for a project that provided an opportunity for people with younger onset dementia to return to the workplace one day per week. Participants in the workplace project used photography to create a record of their experience of returning to the workplace. Based on the nature of the participant's comments, photographs were grouped into four broad areas: impact of dementia, impact on family, the work experience and new friends. Issues related to the use of photography with people who have dementia are explored based on the experiences gained during this project. © The Author(s) 2014.

    Growth hormone receptor deficiency (GHRD) results in short stature, enhanced insulin sensitivity, and low circulating levels of insulin and insulin-like growth factor 1 (IGF-1). Previous studies in mice and humans suggested that GHRD has protective effects against age-related diseases, including cancer and diabetes. Whereas GHRD mice show improved age-dependent cognitive performance, the effect of GHRD on human cognition remains unknown. Using MRI, we compared brain structure, function, and connectivity between 13 people with GHRD and 12 unaffected relatives. We assessed differences in white matter microstructural integrity, hippocampal volume, subregional volumes, and cortical thickness and surface area of selected regions. We also evaluated brain activity at rest and during a hippocampal-dependent pattern separation task. The GHRD group had larger surface areas in several frontal and cingulate regions and showed trends toward larger dentate gyrus and CA1 regions of the hippocampus. They had lower mean diffusivity in the genu of the corpus callosum and the anterior thalamic tracts. The GHRD group showed enhanced cognitive performance and greater task-related activation in frontal, parietal, and hippocampal regions compared with controls. Furthermore, they had greater functional synchronicity of activity between the precuneus and the rest of the default mode network at rest. The results suggest that, compared with controls, GHRD subjects have brain structure and function that are more consistent with those observed in younger adults reported in previous studies. Further investigation may lead to improved understanding of underlying mechanisms and could contribute to the identification of treatments for age-related cognitive deficits. SIGNIFICANCE STATEMENT People and mice with growth hormone receptor deficiency (GHRD or Laron syndrome) are protected against age-related diseases including cancer and diabetes. However, in humans, it is unknown whether cognitive

    There is no baseline activity scale yet validated in pediatric patients. The Marx and Tegner scales have been validated in adult patients only. The Tegner scale involves questions not pertinent to children, such as their work activity. The Marx scale is simple, and all its questions can be related to athletic activities. The Marx scale is reliable for use in a pediatric population. Cohort study. Level 2. Patients younger than 18 years were given the Marx activity scale in clinic and again 3 weeks later. The patients were divided into 3 groups, of at least 50 patients each, based on presenting diagnosis: knee injury, lower extremity (non-knee) injury, and upper extremity injury. Test-retest reliability was determined for the overall scores and the individual questions. Differences in scores were also compared based on age (Marx scale had a high intraclass correlation coefficient (ICC) overall as well as for each of its 4 questions. Both older and younger patients had ICCs >0.80, though the older group generally had higher scores. The mean score was 13.55 (out of 16), and 50.6% scored the maximum; only 1.9% scored the minimum. Mean scores for the knee, lower extremity, and upper extremity groups were 13.71 (SD, 3.70), 13.22 (SD, 4.18), and 13.68 (SD, 3.33), respectively (P > 0.05). There also was no difference in total score based on age (P = 0.88). The Marx activity scale is reliable in patients younger than 18 years with injuries to the knee and lower extremities, though the scale was less reliable in patients younger than 14 years. There is a significant ceiling effect present, which limits its overall usefulness. Although there is no other current substitute, the Marx activity scale is not an ideal measurement of younger patients' baseline activity levels. © 2015 The Author(s).

    Physical activity is associated with improved affective experience and enhanced cognitive processing. Potential age differences in the degree of benefit, however, are poorly understood because most studies examine either younger or older adults. The present study examined age differences in cognitive performance and affective experience immediately following a single bout of moderate exercise. Participants (144 community members aged 19 to 93) were randomly assigned to one of two experimental conditions: (a) exercise (15 min of moderate intensity stationary cycling) or (b) control (15 min completing ratings of neutral IAPS images). Before and after the manipulation, participants completed tests of working memory and momentary affect experience was measured. Results suggest that exercise is associated with increased levels of high-arousal positive affect (HAP) and decreased levels of low-arousal positive affect (LAP) relative to control condition. Age moderated the effects of exercise on LAP, such that younger age was associated with a drop in reported LAP postexercise, whereas the effects of exercise on HAP were consistent across age. Exercise also led to faster RTs on a working memory task than the control condition across age. Self-reported negative affect was unchanged. Overall, findings suggest that exercise may hold important benefits for both affective experience and cognitive performance regardless of age.

    To investigate the potential association between snoring and other symptoms indicative of sleep-disordered breathing and metabolic syndrome (MetS) in Hispanic adolescents and younger adults using a large population-based survey. Sleep-related information, anthropometric measurements and fasting blood samples markers of MetS were obtained from subjects aged 15-40 years collected through the 2nd Chilean Health Survey. Regression models were constructed to evaluate the associations of snoring with MetS, hypertension and serum cholesterol levels. The modulating effect of sleep duration was accounted for in the models. A total of 2147 subjects (42% males, mean age 27.9±7.6 years) were included. Snoring and short sleep duration were present in 43.5 and 25% of the entire population, respectively. MetS was detected in 19.5% of the subjects. In the adjusted regression model, the odds of MetS among snoring subjects were 2.13 times higher (95% confidence interval (CI): 1.52-2.99; Psnoring after adjusting for confounders. In addition, snoring was associated with an increase of 7.26  and 6.56 mg dl -1 for total and low-density lipoprotein cholesterol, respectively, even after adjusting for age, sex and body mass index. Short sleep duration was associated with a small albeit significant risk increase for high systolic blood pressure. In this large population-based sample of young Hispanic adults and adolescents, snoring, but not sleep duration, emerged as an independent risk factor for dyslipidemia and MetS, but not for hypertension.

    The current study measured forgetting in a time-based, naturalistic prospective memory (PM) task. In Experiment 1, younger and older participants were asked to mail a stamped postcard on a date that was delayed 1, 2, 5, 14, or 28 days in the future. In Experiment 2, a different sample of older participants completed the same task with similar delays to replicate results for the older sample in Experiment 1. Overall, older participants were more likely than younger participants to mail the postcard on time. In addition, delay affected on-time return rates more for the younger participants than the older participants. Younger participants' return rates illustrated the typical forgetting curve seen in numerous retrospective memory studies (i.e., rapid decline at shorter delays and slower decline for longer delays). However, older participants' return rates only declined at the longest delays. These results indicate that time-based PM performance declines with an increase in delay, but the form of the decline may differ across age groups.

  1. Older adults, unlike younger adults, do not modulate alpha power to suppress irrelevant information.

    This study examines the neural mechanisms through which younger and older adults ignore irrelevant information, a process that is necessary to effectively encode new memories. Some age-related memory deficits have been linked to a diminished ability to dynamically gate sensory input, resulting in problems inhibiting the processing of distracting stimuli. Whereas oscillatory power in the alpha band (8-12 Hz) over visual cortical areas is thought to dynamically gate sensory input in younger adults, it is not known whether older adults use the same mechanism to gate out sensory input. Here we identified a task in which both older and younger adults could suppress the processing of irrelevant sensory stimuli, allowing us to use electroencephalography (EEG) to explore the neural activity associated with suppression of visual processing. As expected, we found that the younger adults' suppression of visual processing was correlated with robust modulation of alpha oscillatory power. However, older adults did not modulate alpha power to suppress processing of visual information. These results demonstrate that suppression of alpha power is not necessary to inhibit the processing of distracting stimuli in older adults, suggesting the existence of alternative strategies for suppressing irrelevant, potentially distracting information.

    The aim of this study was to examine the effects of an alertness-maintaining task (AMT) in older, fatigued drivers. Fatigue during driving increases crash risk, and previous research suggests that alertness and driving in younger adults may be improved using a secondary AMT during boring, fatigue-eliciting drives. However, the potential impact of an AMT on driving has not been investigated in older drivers whose ability to complete dual tasks has been shown to decline and therefore may be negatively affected with an AMT in driving. Younger ( n = 29) and older drivers ( n = 39) participated in a 50-minute simulated drive designed to induce fatigue, followed by four 10-minute sessions alternating between driving with and without an AMT. Younger drivers were significantly more affected by fatigue on driving performance than were older drivers but benefitted significantly from the AMT. Older drivers did not demonstrate increased driver errors with fatigue, and driving did not deteriorate significantly during participation in the AMT condition, although their speed was significantly more variable with the AMT. Consistent with earlier research, an AMT applied during fatiguing driving is effective in improving alertness and reducing driving errors in younger drivers. Importantly, older drivers were relatively unaffected by fatigue, and use of an AMT did not detrimentally affect their driving performance. These results support the potential use of an AMT as a new automotive technology to improve fatigue and promote driver safety, though the benefits of such technology may differ between different age groups.

    Dyslipidemia may occur in younger adults (defined as persons aged 21 to 39 years) and is an important risk factor for cardiovascular disease. Screening might identify younger adults with asymptomatic dyslipidemia who may benefit from lipid-lowering therapies. To update the 2008 U.S. Preventive Services Task Force review on dyslipidemia screening in younger adults. The Cochrane Central Register of Controlled Trials, the Cochrane Database of Systematic Reviews, and MEDLINE through May 2016, and reference lists. Randomized, controlled trials; cohort studies; and case-control studies on screening for or treatment of asymptomatic dyslipidemia in adults aged 21 to 39 years. The plan was for 1 investigator to abstract data and a second to check their accuracy, and for 2 investigators to independently assess study quality; however, no studies met the inclusion criteria. No study evaluated the effects of lipid screening versus no screening, treatment versus no treatment, or delayed versus earlier treatment on clinical outcomes in younger adults. In addition, no study evaluated the diagnostic yield of alternative screening strategies (such as targeted screening of persons with a family history of hyperlipidemia vs. general screening) in younger adults. No direct relevant evidence. Direct evidence on the benefits and harms of screening for or treatment of dyslipidemia in younger adults remains unavailable. Estimating the potential effects of screening for dyslipidemia in this population requires extrapolation from studies performed in older adults. Agency for Healthcare Research and Quality.

    Aging is associated with decline in both cognitive and auditory abilities. However, evidence suggests that music perception is relatively spared, despite relying on auditory and cognitive abilities that tend to decline with age. It is therefore likely that older adults engage compensatory mechanisms which should be evident in the underlying functional neurophysiology related to processing music. In other words, the perception of musical structure would be similar or enhanced in older compared to younger adults, while the underlying functional neurophysiology would be different. The present study aimed to compare the electrophysiological brain responses of younger and older adults to melodic incongruities during a passive and active listening task. Older and younger adults had a similar ability to detect an out-of-tune incongruity (i.e., non-chromatic), while the amplitudes of the ERAN and P600 were reduced in older adults compared to younger adults. On the other hand, out-of-key incongruities (i.e., non-diatonic), were better detected by older adults compared to younger adults, while the ERAN and P600 were comparable between the two age groups. This pattern of results indicates that perception of tonal structure is preserved in older adults, despite age-related neurophysiological changes in how melodic violations are processed.

    Prior research indicates that older adults (60+ years) are less subject to the sunk-cost fallacy compared with younger adult college students. The objective of this research was to determine if age-related differences in decisions about sunk costs reflected differences in what was salient to individuals about the situation when they described their decision-making goals. Using hypothetical decision-making scenarios, we examined older (N = 21) and younger (N = 20) adults' decisions about sunk costs. Participants responded to open-ended interview questions about their decision-making goals. A coding scheme was developed using qualitative methods and was used to reliably categorize the issues and concerns people expressed when describing their decision-making goals. Compared with younger adults, older adults were less likely to commit the sunk-cost fallacy and were more likely to make normatively correct decisions. When describing their goals, older adults were less likely to focus on the presence or absence of the prior investment (the sunk cost). The salience of investment-related information to individuals when describing their goals mediated age-related differences in the sunk-cost fallacy and normatively correct decisions. The results illustrate how consideration of people's own perspectives of decision-making situations may inform understanding of age-related differences in decision-making fallacies.

    Older adults may devote more cognitive resources to the processing and regulation of emotion stimuli than younger adults, but no studies have determined associations between episodic memory performance and naturalistic emotion recovery in a mixed-age sample. The current study ascertained if episodic memory scores were associated with emotion recovery in younger and midlife/older adults and if these associations were moderated by age. Participants watched a montage of film clips about interpersonal loss. Self-reported negative and positive emotions were assessed prior to the video, immediately after, and again 10 min after the video. Executive functions, processing speed, and episodic memory were assessed. Participants with better episodic memory recovered more quickly from the mood induction than participants with lower scores. Age moderated the association between joviality recovery and memory. Specifically, there was a significantly stronger, positive association between joviality recovery and memory in midlife/older adults relative to younger adults. Stronger memory may facilitate emotion recovery, and this may be particularly true for older adults. Older adults with memory impairment may be at risk for emotion dysregulation.

    The fact that tyrosine increases dopamine availability that, in turn, may enhance cognitive performance has led to numerous studies on healthy young participants taking tyrosine as a food supplement. As a result of this dietary intervention, participants show performance increases in working memory and executive functions. However, the potential association between habitual dietary tyrosine intake and cognitive performance has not been investigated to date. The present study aims at clarifying the association of episodic memory (EM), working memory (WM) and fluid intelligence (Gf), and tyrosine intake in younger and older adults. To this end, we acquired habitual tyrosine intake (food frequency questionnaire) from 1724 participants of the Berlin Aging Study II (1383 older adults, 341 younger adults) and modelled its relations to cognitive performance assessed in a broad battery of cognitive tasks using structural equation modeling. We observed a significant association between tyrosine intake and the latent factor capturing WM, Gf, and EM in the younger and the older sample. Due to partial strong factorial invariance between age groups for a confirmatory factor analysis on cognitive performance, we were able to compare the relationship between tyrosine and cognition between age groups and found no difference. Above and beyond previous studies on tyrosine food supplementation the present result extend this to a cross-sectional association between habitual tyrosine intake levels in daily nutrition and cognitive performance (WM, Gf, and EM). This corroborates nutritional recommendations that are thus far derived from single-dose administration studies.

    Percutaneous needle biopsy (PNB) of the breast is commonly used for diagnosis of breast pathology, but has been less studied in young women. We sought to determine the effectiveness and necessity of PNB in patients younger than 35 years of age. The charts of sequential patients BIRADS) ≥4 in 137 (75.7%) cases, with mass on imaging in 139 (76.8%). Carcinoma was diagnosed in 12 (6.6%), PNB in eight unique patients (6.3%). Other PNB pathology included atypia in four (2.2%) patients; papillary lesion, five (2.8%); benign lymph node, 10 (5.5%); fibroepithelial lesion, 15 (8.3%); benign breast tissue, 63 (34.8%); and fibroadenoma, 72 (39.8%). Women with atypia or malignancy were older than those with benign findings (30.9 vs 28.0 years, P = 0.002). No other patient or imaging factors were significantly associated with pathologic diagnosis on PNB. Routine PNB for all BIRADS 4 findings may be over-used in young women as most results are benign and subsequent surgical findings are concordant. Improved diagnostic accuracy of breast imaging is warranted to reduce unnecessary procedures.

    This cross-sectional study of 540 homeless ex-offenders exiting prisons and jails assessed sociodemographic, childhood, and drug-related differences. Older ex-offenders from prison were more likely to have been married, come from a two-parent family, and used crack, whereas younger ex-offenders from prison were more likely to have used methamphetamine. Older ex-offenders from jail were more likely to be African American, have children, and report a history of crack and injection drug use, whereas younger ex-offenders from jail were more likely to have engaged in binge drinking and be in a gang. Our findings showcase the need to understand unique correlates of younger and older incarcerated populations.

    Auditory-visual (AV) speech enhances speech perception and facilitates auditory processing, as measured by event-related brain potentials (ERPs). Considering a perspective of shared resources between perceptual and cognitive processes, facilitated speech perception may render more resources available for higher-order functions. This study examined whether AV speech facilitation leads to better working memory (WM) performance in 23 younger and 20 older adults. Participants completed an n-back task (0- to 3-back) under visual-only (V-only), auditory-only (A-only), and AV conditions. The results showed faster responses across all memory loads and improved accuracy in the most demanding conditions (2- and 3-back) during AV compared with unisensory conditions. Older adults benefited from the AV presentation to the same extent as younger adults. WM performance of older adults during the AV presentation did not differ from that of younger adults in the A-only condition, suggesting that an AV presentation can help to counteract some of the age-related WM decline. The ERPs showed a decrease in the auditory N1 amplitude during the AV compared with A-only presentation in older adults, suggesting that the facilitation of perceptual processing becomes especially beneficial with aging. Additionally, the N1 occurred earlier in the AV than in the A-only condition for both age groups. These AV-induced modulations of auditory processing correlated with improvement in certain behavioral and ERP measures of WM. These results support an integrated model between perception and cognition, and suggest that processing speech under AV conditions enhances WM performance of both younger and older adults.

    Successful performance of a memory-guided motor task requires participants to store and then recall an accurate representation of the motor goal. Further, participants must monitor motor output to make adjustments in the absence of visual feedback. The goal of this study was to examine memory-guided grip force in healthy younger and older adults and compare it to performance on behavioral tasks of working memory. Previous work demonstrates that healthy adults decrease force output as a function of time when visual feedback is not available. We hypothesized that older adults would decrease force output at a faster rate than younger adults, due to age-related deficits in working memory. Two groups of participants, younger adults (YA: N = 32, mean age 21.5 years) and older adults (OA: N = 33, mean age 69.3 years), completed four 20-s trials of isometric force with their index finger and thumb, equal to 25% of their maximum voluntary contraction. In the full-vision condition, visual feedback was available for the duration of the trial. In the no vision condition, visual feedback was removed for the last 12 s of each trial. Participants were asked to maintain constant force output in the absence of visual feedback. Participants also completed tasks of word recall and recognition and visuospatial working memory. Counter to our predictions, when visual feedback was removed, younger adults decreased force at a faster rate compared to older adults and the rate of decay was not associated with behavioral performance on tests of working memory.

    The fear-avoidance model of pain accounts for the debilitating consequences of strong fear as a component of reactions to painful conditions (eg, movements become anxiety-provoking because they cause pain). The model, which is supported in the literature, posits that fear of pain interferes with recovery because it leads to avoidance of beneficial activity. Despite the high prevalence of pain among the elderly, investigations of fear of pain in this population are scarce. A related construct, fear of falling, has been studied among elderly (but not younger) adults as an age-specific concern. To examine the relationship between fear of pain and fear of falling. Specifically, it is hypothesized that fear of pain and fear of falling are distinct constructs. Moreover, the authors investigated whether fear of falling becomes more relevant with increasing age in a sample of seniors and younger adults with musculoskeletal conditions. A convenience sample of younger and older adult physiotherapy outpatients (n=226) receiving treatment for musculoskeletal conditions were recruited for the study. Fear of pain and fear of falling were assessed using self-report measures. There were no age differences with respect to fear of pain and fear of falling. Regression analyses showed that fear of pain measures contribute substantial unique variance to the prediction of each other; however, they only make minor unique contributions to the prediction of fear of falling. Similar results were obtained through confirmatory analyses using structural modelling techniques. The analyses supported the distinctiveness of fear of pain and fear of falling. Moreover, among physiotherapy outpatients with musculoskeletal pain conditions, fear of falling and fear of pain are distinct constructs that appear to represent the concerns of both seniors and younger pain patients.

    Diarrheal disease is among the leading causes of death in children younger than 5 years, especially in developing countries. The aim of this study was to investigate the most frequent etiological agents of diarrhea and its associated factors in children younger than 5 years attending the Bengo General Hospital in Angola. From September 2012 through December 2013, stool samples were collected from 344 children presenting with diarrhea to investigate the presence of viral, bacterial and parasitic agents. Relevant sociodemographic and clinical data were obtained from parents and caregivers. An enteric pathogen was detected in 66.6% of stool samples: Cryptosporidium spp. (30.0%), rotavirus (25.1%), Giardia lamblia (21.6%), diarrheagenic Escherichia coli (6.3%), Ascaris lumbricoides (4.1%), adenovirus (3.8%), Strongyloides stercoralis (3.5%), astrovirus (2.6%), Hymenolepis nana (1.7%), Entamoeba histolytica/dispar (0.9%), Taenia spp. (0.6%), Trichuris trichiura (0.3%) and Entamoeba histolytica (0.3%). Children younger than 12 months were more frequently infected with Cryptosporidium spp. compared with older children (age: 12-59 months), independently of sex, season, lethargy and wasting [odds ratio (OR): 3.5, 95% confidence interval (95% CI): 2.0-6.2]. Age (OR: 5.0, 95% CI: 2.6-9.3), vomiting (OR: 2.7, 95% CI: 1.5-4.8) and type of admission (inpatients, OR: 0.5, 95% CI: 0.3-0.9) were significantly associated with rotavirus infection. This study demonstrates high rates of infection with an enteric pathogen, particularly in children younger than 12 months, emphasizing the need to address diarrheal disease in this age group.

  16. A Younger Dryas plateau icefield in the Monadhliath, Scotland, and implications for regional palaeoclimate

    A record of Younger Dryas glaciation in Scotland is well established. However, the role of the Monadhliath, a significant plateau area extending over 840 km2 in central Scotland, has never been investigated systematically. We present the first systematic glacial geomorphological mapping across the whole region, which has led to the identification of hitherto-unrecorded glacial and associated landforms. The spatial distribution of these landforms indicates that the last phase of glaciation in the area was that of a local plateau icefield. In addition, a clear morphostratigraphical signature provides a strong indication that the icefield dates to the Younger Dryas (12.9-11.7 ka), which is supported by numerical ages in the southeast of the study area. Based on the geomorphological evidence and 2D glacier surface profile modelling, a 280 km2 icefield is reconstructed. A novel approach is introduced to quantify plateau icefield thickness for equilibrium line altitude (ELA) and palaeoprecipitation calculations, resulting in greater overall data confidence compared to traditional reconstruction methods. The ELA for the whole icefield is calculated to be 714 ± 25 m, whilst the ELAs of individual outlet glaciers range from 560 m in the west to 816 m in the east, demonstrating a significant W-E precipitation gradient across the region during the Younger Dryas. These ELAs compare well with those calculated for Younger Dryas ice masses reconstructed in neighbouring regions and are in good agreement with overall precipitation patterns suggested for Scotland during this time. Whilst the total amount of precipitation calculated from these ELAs is highly dependent on the method used, irrespective of this, the study suggests a more arid Younger Dryas climate in the region compared to the present day.

    Variability in sea level is a fundamental measure of past changes in continental ice volume and provides an important benchmark to test climate change hypotheses. Records of the most recent deglaciation show two pulses of accelerated sea-level rise (Meltwater Pulses 1A and 1B) separated by an interval of slower sea level rise. The Younger Dryas chronozone falls within the interval between MWP 1A and 1B. It was first described over 100 years ago and remains one of the most studied periods in Earth’s history. The Younger Dryas was originally constrained with 14C dating to the interval between 11,000 and 10,000 14C years BP, which converts to 13,000 to 11,640 calendar years BP. The climatic expression of the Younger Dryas was most pronounced in the circum North Atlantic where climate proxies returned in some regions to near glacial values. Interpretations of the Younger Dryas’ significance range from a catastrophic global cooling event accompanied by Northern hemisphere ice sheet growth to simply regional changes in ocean and air mass mixing zones confined mainly to the North Atlantic. A detailed sea level record containing the interval from the end of MWP 1A to the beginning of MWP 1B (~14,000 to 11,300 years BP) was generated using 26 new U/Th dates from our 2007 Barbados offshore drilling expedition combined with our 1988 expedition measurements. 16 of these dates fall within the Younger Dryas Chronozone. Younger Dryas sea level positions were based on Acropora palmata samples from 3 overlapping and contemporaneous offshore drill cores (RGF 12 and BBDS 9 & 10) and corrected for minor tectonic uplift. From 14,000 to 11,300 years BP, sea level rose from ~81 to 56.5 m below present sea level with an initial rate of 10 m/kyr that decreased smoothly to <5 m/kyr at the base of MWP 1B. At the beginning of the Younger Dryas, sea level was at 69 m below present and rose 8 m by the end of this interval. In the context of the Barbados sea level record, the Younger Dryas

    Better-performing younger adults typically express greater brain signal variability relative to older, poorer performers. Mechanisms for age and performance-graded differences in brain dynamics have, however, not yet been uncovered. Given the age-related decline of the dopamine (DA) system in normal cognitive aging, DA neuromodulation is one plausible mechanism. Hence, agents that boost systemic DA [such as d-amphetamine (AMPH)] may help to restore deficient signal variability levels. Furthermore, despite the standard practice of counterbalancing drug session order (AMPH first vs. placebo first), it remains understudied how AMPH may interact with practice effects, possibly influencing whether DA up-regulation is functional. We examined the effects of AMPH on functional-MRI-based blood oxygen level-dependent (BOLD) signal variability (SD(BOLD)) in younger and older adults during a working memory task (letter n-back). Older adults expressed lower brain signal variability at placebo, but met or exceeded young adult SD(BOLD) levels in the presence of AMPH. Drug session order greatly moderated change-change relations between AMPH-driven SD(BOLD) and reaction time means (RT(mean)) and SDs (RT(SD)). Older adults who received AMPH in the first session tended to improve in RT(mean) and RT(SD) when SD(BOLD) was boosted on AMPH, whereas younger and older adults who received AMPH in the second session showed either a performance improvement when SD(BOLD) decreased (for RT(mean)) or no effect at all (for RT(SD)). The present findings support the hypothesis that age differences in brain signal variability reflect aging-induced changes in dopaminergic neuromodulation. The observed interactions among AMPH, age, and session order highlight the state- and practice-dependent neurochemical basis of human brain dynamics.

    Full Text Available Today computer games occupy a significant place in children’s lives and fundamentally affect the process of the formation and development of their personalities. A number of present-day researchers assert that computer games have a developmental effect on players. Others share the point of view that computer games have negative effects on the cognitive and emotional spheres of a child and claim that children with low self-esteem who neglect their schoolwork and have difficulties in communication are particularly passionate about computer games. This article reviews theoretical and experimental pedagogical and psychological studies of the nature of the correlation between a passion for computer games and the school performance of younger schoolchildren. Our analysis of foreign and Russian psychology studies regarding the problem of playing activities mediated by information and computer technologies allowed us to single out the main criteria for children’s passion for computer games and school performance. This article presents the results of a pilot study of the nature of the correlation between a passion for computer games and the school performance of younger schoolchildren. The research involved 32 pupils (12 girls and 20 boys aged 10-11 years in the 4th grade. The general hypothesis was that there are divergent correlations between the passion of younger schoolchildren for computer games and their school performance. A questionnaire survey administered to the pupils allowed us to obtain information about the amount of time they devoted to computer games, their preferences for computer-game genres, and the extent of their passion for games. To determine the level of school performance we analyzed class registers.

    This study investigates the extent to which age-related language processing difficulties are due to a decline in sensory processes or to a deterioration of cognitive factors, specifically, attentional control. Two facets of attentional control were examined: inhibition of irrelevant information and divided attention. Younger and older adults were asked to categorize the initial phoneme of spoken syllables ("Was it m or n?"), trying to ignore the lexical status of the syllables. The phonemes were manipulated to range in eight steps from m to n. Participants also did a discrimination task on syllable pairs ("Were the initial sounds the same or different?"). Categorization and discrimination were performed under either divided attention (concurrent visual-search task) or focused attention (no visual task). The results showed that even when the younger and older adults were matched on their discrimination scores: (1) the older adults had more difficulty inhibiting lexical knowledge than did younger adults, (2) divided attention weakened lexical inhibition in both younger and older adults, and (3) divided attention impaired sound discrimination more in older than younger listeners. The results confirm the independent and combined contribution of sensory decline and deficit in attentional control to language processing difficulties associated with aging. The relative weight of these variables and their mechanisms of action are discussed in the context of theories of aging and language. (c) 2014 APA, all rights reserved.

    Full Text Available Abstract Background Patellofemoral osteoarthritis (PFOA is a common form of knee OA in middle and older age, but its relation to PF disorders and symptoms earlier in life is unclear. Our aim was to conduct a systematic review to investigate the strength of evidence for an association between anterior knee pain (AKP in younger adults and subsequent PFOA. Methods The search strategy included electronic databases (Pubmed, EMBASE, AMED, CINAHL, Cochrane, PEDro, SportDiscus: inception to December 2009, reference lists of potentially eligible studies and selected reviews. Full text articles in any language, - identified via English titles and abstracts, were included if they were retrospective or prospective in design and contained quantitative data regarding structural changes indicative of PFOA, incident to original idiopathic AKP. Eligibility criteria were applied to titles, abstracts and full-texts by two independent reviewers. Data extraction included study location, design, date, sampling procedure, sample characteristics, AKP/PFOA definitions, follow-up duration and rate, and main findings. Foreign language articles were translated into English prior to examination. Results Seven articles satisfied eligibility (5 English, 2 German. Only one case-control study directly investigated a link between PFOA and prior AKP, providing level 3b evidence in favour of an association (OR 4.4; 95%CI 1.8, 10.6. Rough estimates of the annual risk of PFOA from the remaining six small, uncontrolled, observational studies (mean follow-up range: 5.7 to 23 years ranged from 0% to 3.4%. This was not the primary aim of these studies, and limitations in design and methodology mean this data should be interpreted with caution. Conclusions There is a paucity of high-quality evidence reporting a link between AKP and PFOA. Further, well-designed cohort studies may be able to fill this evidence gap.

    The Younger Dryas impact hypothesis contends that an extraterrestrial object exploded over North America at 12.9 ka, initiating the Younger Dryas cold event, the extinction of many North American megafauna, and the demise of the Clovis archeological culture. Although the exact nature and location of the proposed impact or explosion remain unclear, alleged evidence for the fallout comes from multiple sites across North America and a site in Belgium. At 6 of the 10 original sites (excluding the Carolina Bays), elevated concentrations of various "impact markers" were found in association with black mats that date to the onset of the Younger Dryas. Black mats are common features in paleowetland deposits and typically represent shallow marsh environments. In this study, we investigated black mats ranging in age from approximately 6 to more than 40 ka in the southwestern United States and the Atacama Desert of northern Chile. At 10 of 13 sites, we found elevated concentrations of iridium in bulk and magnetic sediments, magnetic spherules, and/or titanomagnetite grains within or at the base of black mats, regardless of their age or location, suggesting that elevated concentrations of these markers arise from processes common to wetland systems, and not a catastrophic extraterrestrial impact event.

    Objectives. We compared the characteristics of emergency department (ED) visits of older versus younger homeless adults. Methods. We analyzed 2005–2009 data from the National Hospital Ambulatory Medical Care Survey, a nationally representative survey of visits to hospitals and EDs, and used sampling weights, strata, and clustering variables to obtain nationally representative estimates. Results. The ED visits of homeless adults aged 50 years and older accounted for 36% of annual visits by homeless patients. Although demographic characteristics of ED visits were similar in older and younger homeless adults, clinical and health services characteristics differed. Older homeless adults had fewer discharge diagnoses related to psychiatric conditions (10% vs 20%; P = .002) and drug abuse (7% vs 15%; P = .003) but more diagnoses related to alcohol abuse (31% vs 23%; P = .03) and were more likely to arrive by ambulance (48% vs 36%; P = .02) and to be admitted to the hospital (20% vs 11%; P = .003). Conclusions. Older homeless adults’ patterns of ED care differ from those of younger homeless adults. Health care systems need to account for these differences to meet the needs of the aging homeless population. PMID:23597348

    Although many studies have shown that short falls by children rarely result in serious injury, no recent study in the United States has assessed the prevalence and the characteristics of such falls. Because the history of a short fall often is given in the instance of suspected child abuse, data addressing the characteristics, the frequency, and the severity of such falls would assist in abuse investigations. Anonymous questionnaires were distributed at primary care offices to parents of children younger than 5 years. Parents answered a series of questions regarding any falls their children had sustained before the age of 2 years. Information gathered included the age of the child at the time of the fall, the details about the fall, the medical attention sought, and any injuries sustained. We received a total of 307 eligible surveys. There were 209 falls reported for 122 children. Only 24% of those children sustained any injury as a result of the fall. Most (85%) of the children who sustained injuries had a bruise or a bump. Of the 20% (40 children) who were brought for medical care, only 13 children received medical treatment. The most severe injuries were in 2 children who sustained concussions; only 4 children had permanent injury (cutaneous scars). Children who fell on a hard surface were 6 times more likely to have an injury compared with children who fell on a soft surface (P = 0.001) In addition, for every 1 unit increase in fall height, risk of injury increased by a factor of 2.3. In short falls, ground surface and fall height were significant predictors of injury risk. The results of this study also support the opinion that short falls rarely cause injury. Therefore, a history of a short fall in a seriously injured child should raise the suspicion of child abuse.

    To analyze whether the information found on popular Internet sites are in accordance with the steps recommended by the Food Guide for Children Younger than Two Years of the Ministry of Health (2010). Descriptive/comparative study, carried out between August and October 2014, which carried out a search for popular sites (for lay people) in Portuguese, containing information on nutrition of children younger than two years. The Google search engine was used. These findings were compared with the Food Guide for Children Younger than Two Years of the Ministry of Health (2010). It was verified whether the information shown on the websites was in accordance with the Guide. A total of 50 sites were analyzed, including blogs, food company websites and websites specialized in child nutrition. Only 10% of those pages correctly showed every step of the Food Guide. The recommendations were: exclusive breastfeeding up to six months of life (80%); complementary feeding from six months of life (36%); baby food consistency according to the guide (48%); encouraging the consumption of fruits and vegetables daily (60%). Regarding the complementary feeding safety and hygiene, 26% contained correct information. Only 36% correctly warned about which foods should be avoided in the first years of life. The information found on the sites is largely in disagreement with the Ministry of Health recommendations, which can lead to misconceptions in the nutritional care of the children younger than two years.

  7. Critical Flicker Fusion Predicts Executive Function in Younger and Older Adults.

    2015-11-01

    Critical flicker fusion (CFF), a measure of visual processing speed, has often been regarded as a basic metric underlying a number of higher cognitive functions. To test this, we measured CFF, global cognition, and several cognitive subdomains. Because age is a strong covariate for most of these variables, both younger (n = 72) and older (n = 57) subjects were measured. Consistent with expectations, age was inversely related to CFF and performance on all of the cognitive measures except for visual memory. In contrast, age-adjusted CFF thresholds were only positively related to executive function. Results showed that CFF predicted executive function across both age groups and accounted for unique variance in performance above and beyond age and global cognitive status. The current findings suggest that CFF may be a unique predictor of executive dysfunction. © The Author 2015. Published by Oxford University Press. All rights reserved.

  8. Clear speech and lexical competition in younger and older adult listeners.

    2017-08-01

    This study investigated whether clear speech reduces the cognitive demands of lexical competition by crossing speaking style with lexical difficulty. Younger and older adults identified more words in clear versus conversational speech and more easy words than hard words. An initial analysis suggested that the effect of lexical difficulty was reduced in clear speech, but more detailed analyses within each age group showed this interaction was significant only for older adults. The results also showed that both groups improved over the course of the task and that clear speech was particularly helpful for individuals with poorer hearing: for younger adults, clear speech eliminated hearing-related differences that affected performance on conversational speech. For older adults, clear speech was generally more helpful to listeners with poorer hearing. These results suggest that clear speech affords perceptual benefits to all listeners and, for older adults, mitigates the cognitive challenge associated with identifying words with many phonological neighbors.

  13. Welfare of Aged Horses

    Directory of Open Access Journals (Sweden)

    2011-10-01

    Full Text Available Horses form a unique and special part of their owners’ lives and aged horses are no exception. This review considers the health and management of aged horses, including the role of the owner and their perceptions of aged horses, potential threats or risks to their welfare and finally, factors affecting quality of life and euthanasia of aged horses. Owners of aged horses are concerned about the health, welfare and quality of life of their aged animals. Yet surveys of management and preventive healthcare reflect that there may be some limitations to what owners are actually achieving in practice. They show declining management as horses age, particularly for the retired horse and insufficient appropriate preventive healthcare via veterinary surgeons. The veterinary surgeon plays an essential and influential role in preventive healthcare, management of diseases and disorders and ultimately in the decision making process for euthanasia of aged horses at the end of their lives. The value of aged horses should not be underestimated by veterinarians and others working with them and the continuing care of aged horses should be regarded with the same importance as the care of younger horses with more obvious monetary value.

  14. Younger and older adults' beliefs about the experience and expression of emotions across the life span.

    Although theorists acknowledge that beliefs about emotions may play a role in age-related emotion behavior, no research has explored these beliefs. This research examined beliefs about the experience and expression of emotions across the life span, especially across the adult years. Younger and older adults rated the extent to which infants, children, adolescents, young adults, middle-aged adults, and older adults were likely to experience and express a range of emotions. Younger and older adults held similar beliefs about the course of emotions across the life span. Moreover, these beliefs differed across emotion categories. In particular, although older adults were believed to experience and express fewer highly charged, negative emotions, they were expected to be more likely to experience and express positive, low arousal emotions, as well as negative, low arousal emotions. The experience and expression of positive, high arousal emotions were seen as more characteristic of very young age groups as opposed to older age groups. These findings beg questions about if and how beliefs about emotion may affect age-related emotion regulation strategies and other everyday emotion-focused behaviors, as well as social reactions to older adults observed experiencing and expressing particular types of emotions. © The Author 2013.

    2015-01-01

    Sharing stories is an important social activity in everyday life. This study used fine-grained content analysis to investigate the accuracy of recall of two central story elements: the gist and detail of socially-relevant stories. Younger (M age = 28.06) and older (M age = 75.03) American men and women (N = 63) recalled fictional stories that were coded for (i) accuracy of overall gist and specific gist categories and (ii) accuracy of overall detail and specific detail categories. Findings showed no age group differences in accuracy of overall gist or detail, but differences emerged for specific categories. Older adults more accurately recalled the gist of when the event occurred whereas younger adults more accurately recalled the gist of why the event occurred. These differences were related to episodic memory ability and education. For accuracy in recalling details, there were some age differences, but gender differences were more robust. Overall, women remembered details of these social stories more accurately than men, particularly time and perceptual details. Women were also more likely to accurately remember the gist of when the event occurred. The discussion focuses on how accurate recall of socially-relevant stories is not clearly age-dependent but is related to person characteristics such as gender and episodic memory ability/education.

    Our previous work demonstrated differential neurobehavioral effects of low-dose alcohol consumption on older and younger adults in a driving simulator. However, the ability to enhance or suppress a response in such context has yet to be examined. The current study contrasted older and younger drivers' responses to specific stimuli (i.e., relevant, irrelevant) in scenarios of differing complexity following low-dose acute alcohol administration. Healthy older (55-70) and younger (25-35) adults completed two driving scenarios (i.e., country and metropolis) both before and after consuming beverages targeted to reach peak BrACs of 0.00, 0.04, or 0.065%. Throughout the simulation, participants encountered relevant stimuli (e.g., pedestrians walking into the street) and irrelevant stimuli (e.g., pedestrians walking parallel). Peak deceleration, range of steering, and distance until brake application were assessed within a 450-ft window preceding each stimulus. Following low-dose alcohol consumption, older adults shifted from a strategy using both deceleration and steering to relying solely on deceleration in responding to relevant stimuli in the country. Older adults under both low and moderate alcohol conditions displayed an inability to withhold responses to irrelevant stimuli in the metropolis. These findings are consistent with our prior work showing differential effects of low-dose alcohol on older, relative to younger, adults. The interactive effects of age and alcohol, however, depend on stimulus type and environmental complexity. Continued investigation of neurobehavioral mechanisms in ecologically valid paradigms is necessary for understanding the implications of the combined impairing effects of alcohol and older age.

    Learning and memory abilities tend to decline as people age. The current study examines the question of whether a learning situation that emphasizes collaborative social interaction might help older persons overcome age-related learning and memory changes and thus perform similarly to younger persons. Younger and Older participants (n = 34 in each group) completed the Barrier Task, a game-like social interaction where partners work together to develop labels for a set of abstract tangrams. Participants were also administered standard clinical neuropsychological measures of memory, on which the Older group showed expected inferiority to the Younger group. On the Barrier Task, the Older group performed less well than the Younger group early on, but as the task progressed, the performance of the Older group caught up and became statistically indistinguishable from that of the Younger group. These results can be taken to suggest that a learning milieu characterized by collaborative social interaction can attenuate some of the typical memory disadvantages associated with being older.

    Uranium-series and radiocarbon ages are reported for deep-sea corals Madrepora oculata, Desmophyllum dianthus, Lophelia pertusa and Caryophyllia smithii from the Mediterranean Sea. U-series dating indicates that deep-sea corals have persisted in the Mediterranean for over 480,000 years, especially during cool interstadial periods. The most prolific period of growth however appears to have occurred within the Younger Dryas (YD) period from 12,900 to 11,700 years BP followed by a short (~ 330 years) phase of post-YD coral growth from 11,230 to 10,900 years BP. This indicates that deep-sea corals were prolific in the Mediterranean not only during the return to the more glacial-like conditions of the YD, but also following the rapid deglaciation and transition to warmer conditions that followed the end of the YD. Surprisingly, there is a paucity Last Glacial Maximum (LGM) coral ages, implying they were largely absent during this period when cold-water conditions were more prevalent. Radiocarbon ages show that the intermediate depth waters of the Mediterranean generally had Δ 14C compositions similar to surface waters, indicating that these waters were extremely well ventilated. The only exception is a narrow period in the YD (12,500 ± 100 years BP) when several samples of Lophelia pertusa from the Ionian Sea had Δ 14C values falling significantly below the marine curve. Using a refined approach, isolation ages (τ isol) of 300 years to 500 years are estimated for these intermediate (800-1000 m) depth waters relative to surface marine waters, indicating a reduction or absence of deep-water formation in the Ionian and adjacent Adriatic Seas during the YD. Contrary to previous findings, we find no evidence for widespread intrusion of low Δ 14C Atlantic waters into the Mediterranean. Prolific growth of deep-sea corals in the Mediterranean ended abruptly at ~ 10,900 years BP, with many of the coral-bearing mounds on the continental slopes being draped in a thin veneer

    Obesity prevalence is noticeably growing, even in the elderly. Most of the studies concerning the impact of obesity in the elderly evaluated physical co-morbidities, whilst very few data are available on psychological co-morbidities in people ≥ 60 years of age. The present study aimed to compare anthropometrical measures, physical co-morbidities and psychosocial factors correlated with overweight and obesity in younger and elderly people. In 456 women in the age range of 18-59 years and 128 women in the age range of 60-80 years with body mass index (BMI) ≥ 25/kg m², body weight, height and waist and hip circumferences were measured. The presence of co-morbidities such as osteoarthritis, hypertension, type 2 diabetes and hypercholesterolaemia was assessed. The Obesity Related Well Being 97 Questionnaire (ORWELL 97), Body Uneasiness Test (BUT), Symptom Check List 90 (SCL 90) and Binge Eating Scale (BES) tests were used to evaluate psychometric variables. BMI was not significantly different between younger overweight-obese subjects and older overweight-obese subjects, whereas waist circumference and waist-to-hip ratio (WHR) were significantly higher in the elderly. Osteoarthritis, hypertension and hypercholesterolaemia were significantly more frequent in the elderly. Older overweight-obese subjects had better scores in most of the psychometric questionnaires. Our results show that older overweight-obese subjects have generally more physical co-morbidities but a better psychological status than younger adults, despite similar BMI. These data may contribute to a better understanding of obesity consequences in the elderly and may help clinicians to differentiate obesity treatments in relation to patients' age.

  8. Evolutionary perspectives on ageing.

    Science.gov (United States)

    2017-10-01

    From an evolutionary perspective, ageing is a decrease in fitness with chronological age - expressed by an increase in mortality risk and/or decline in reproductive success and mediated by deterioration of functional performance. While this makes ageing intuitively paradoxical - detrimental to individual fitness - evolutionary theory offers answers as to why ageing has evolved. In this review, I first briefly examine the classic evolutionary theories of ageing and their empirical tests, and highlight recent findings that have advanced our understanding of the evolution of ageing (condition-dependent survival, positive pleiotropy). I then provide an overview of recent theoretical extensions and modifications that accommodate those new discoveries. I discuss the role of indeterminate (asymptotic) growth for lifetime increases in fecundity and ageing trajectories. I outline alternative views that challenge a universal existence of senescence - namely the lack of a germ-soma distinction and the ability of tissue replacement and retrogression to younger developmental stages in modular organisms. I argue that rejuvenation at the organismal level is plausible, but includes a return to a simple developmental stage. This may exempt a particular genotype from somatic defects but, correspondingly, removes any information acquired during development. A resolution of the question of whether a rejuvenated individual is the same entity is central to the recognition of whether current evolutionary theories of ageing, with their extensions and modifications, can explain the patterns of ageing across the Tree of Life.

    The effects of heart attack, or myocardial infarction (MI), across psychosocial domains may be particularly acute in younger adults, for whom serious health events are non-normative. MI morbidity is declining in Western countries, but in England MI numbers have plateaued for the under-45 cohort, where approximately 90% of patients are male. Qualitative research on younger adults' experience of MI is limited, and no study has sampled exclusively under-45s. This study aimed to understand how a sample of men under 45 adjusted to and made sense of MI. Qualitative research design based on semi-structured in-depth interviews. Ten men aged under 45 who had experienced MI in the past 3-6 months were purposively recruited and interviewed. Interviews were transcribed verbatim and analysed using interpretative phenomenological analysis. Seven superordinate themes were identified. This article focuses in depth on the three most original themes: (1) 'I'm less of a man', which described experiences of losing 'maleness' (strength, independence, ability to provide) post-MI; (2) 'Shortened horizons', which covered participants' sense of foreshortened future and consequent reprioritization; and (3) 'Life loses its colour', describing the loss of pleasure from lifestyle-related changes. Themes broadly overlapped with the qualitative literature on younger adult MI. However, some themes (e.g., loss of 'maleness' post-MI, and ambivalence towards MI risk factors) appeared unique to this study. Themes were also discussed in relation to risk factors for anxiety and depression and how this might inform clinical care for a younger, male population. Statement of contribution What is already known on this subject? Myocardial infarction (MI) morbidity is not declining in England for under-45s. Adjustment to MI is particularly challenging for younger adults, perhaps because it is non-normative. However, little is known about the experience of MI in younger adults. What does this study add?

    To date, research concerning Theory of Mind (ToM) in remitted bipolar disorder (rBD) has yielded inconclusive results. This may be a result of methodological shortcomings and the failure to consider relevant third variables. Furthermore, studies using ecologically valid stimuli are rare. This study examines ToM in rBD patients, using ecologically valid stimuli. Additionally, the effects of sad mood induction (MI) as well as of age and gender are considered. The sample comprises N = 44 rBD patients (rBDPs) and N = 40 healthy controls (HCs). ToM decoding is assessed using the Cambridge Mindreading Face-Voice-Battery (CAM) and ToM reasoning using the Movie for the Assessment of Social Cognition (MASC). Both tasks were divided into two parts to conduct one part with and one without MI. While across the whole sample there was no evidence that rBDPs and HCs differed in ToM decoding or reasoning, in the younger subsample (age age, the decoding deficits in younger rBDPs might be of particular importance not only for social functioning but also for the course of illness. Furthermore, this age-related deficit may explain the inconclusive findings that have been reported so far. Copyright © 2018 Elsevier B.V. All rights reserved.

    AIM: To compare the natural history and course of acute diverticulitis in a younger age group with an older population and to evaluate whether younger patients should be managed differently. METHODS: This study was a retrospective review of 157 patients treated with acute diverticulitis between January 1, 2004 and December 31, 2007. Diverticulitis was stratified according to the Hinchey classification. Patients were divided into 2 populations: group A ≤ 50 years (n = 31); group B > 50 years (n = 126). Mean patient follow-up was 15 mo. RESULTS: The median age was 60 years. A significantly higher proportion of patients in group B presented with complicated diverticulitis (36.5% vs 12.9%, P = 0.01). Recurrence was more frequent in group A (25.8% vs 11.1%, P = 0.03) and the mean time-to-recurrence was shorter (12 mo vs 28 mo, P = 0.26). The most severe recurrent episodes of acute diverticulitis were classified as Hinchey stage I and none of the patients required emergency surgery. In multivariate analysis, only age (P = 0.024) was identified as an independent prognostic factor for recurrence. CONCLUSION: Based on the results of this study, the authors recommend that diverticulitis management should be based on the severity of the disease and not on the age of the patient. PMID:21245993

    By 2030, numbers and proportions of older adults with substance-use problems are expected to increase. While risk factors for problem drinking in late life have been identified, it remains unknown whether these factors drive daily drinking among older problem drinkers. This study examined the daily drivers of drinking among problem drinkers, moderated by age, utilizing ecological momentary assessment (EMA). Participants (N = 139), ages 20-73, received daily EMA online surveys completed via a smartphone prior to initiation of treatment. Multilevel modeling tested the moderating impact of age on within- and between-person relationships between drinking and focal predictors (mood, loneliness, boredom, stress, poor sleep, social factors, alcohol salience, commitment and confidence not to drink heavily). Older adults reported greater alcohol consumption when daily boredom levels were higher. Heavier drinking among younger adults was associated with poorer sleep quality. Greater daily confidence, daily commitment and daily alcohol salience did not impact drinking to the same extent for older adults as for younger adults. Greater person-level commitment predicted reduced drinking equivalently across age, but low person-level commitment predicted greater drinking among older adults compared to their younger counterparts. Older adults may have unique daily drivers of drinking that are not fully realized in current research and intervention efforts. Addressing the growing substance-use treatment needs among this population will require identifying the unique drivers of drinking among older adults, such as boredom, when compared to younger adults.

    The success and long-term survival rates of modern joint arthroplasty leads to a high patient satisfaction and, together with its technical improvements, has broadened the indications to an increasingly younger population. Limitations to the established systems are the long-term survival rates, which are mainly influenced by wear of the articulating parts and the resulting problems. Beside "classic" long-stemmed cemented shafts articulating with metal against polyethylene, short-stemmed or cup designs with a hard-hard self pairing are increasingly used in total hip arthroplasty. This paper reflects the current state of the art in joint arthroplasty for younger patients with the focus on wear couples and discusses future perspectives. Special interest is focused on the advantages and disadvantages of ceramic bearings, problems with allergies to implant components and the design of endoprostheses with regard to avoidance of impingement.

    infections and the risk factors associated with living conditions among children up to 5 years of age in the city of Rio Grande, in the state of Rio Grande do Sul, Brazil. METHODS: A population-based cross-sectional study was carried out with 775 children. A standardized questionnaire was administered to the mother or other caregiver at the child's home in order to collect information on housing conditions, socioeconomic status, and smoking in the home. Additional variables examined included nutritional status, duration of breast-feeding, prenatal care, and utilization of health care services. Environmental variables were analyzed individually and were also grouped together in an "environmental score" that encompassed 10 variables: type of house construction, type of floor, home heating system, type of stove, dog in the child's room, dog in the house, cat in the child's room, cat in the house, number of people per room, and maternal smoking. The grouped environmental score ranged from 0 (best to 10 (worst. The analysis included two stages: a bivariate stage, in which the prevalence ratio was calculated for each risk factor, and a multivariate stage, with logistic regression. RESULTS: The overall prevalence of acute lower respiratory tract infections was 23.9%. The main risk factors identified were: environmental score > 3 points, maternal schooling 30 years was found to protect against the development of respiratory illness. CONCLUSION: Specific programs need to be implemented to control acute respiratory illnesses in the population studied. In future studies with this population, the environmental score that we developed could be used in place of the complete set of environmental variables that we tested. This environmental score should be applied in other contexts so as to determine its external validity.

    We determined the effect of aging on expiratory flow limitation (EFL) and operating lung volumes when matched for lung size. We hypothesized that older adults will exhibit greater EFL and increases in EELV during exercise compared to younger controls. Ten older (5M/5W; >60years old) and nineteen height-matched young adults (10M/9W) were recruited. Young adults were matched for%predicted forced vital capacity (FVC) (Y-matched%Pred FVC; n=10) and absolute FVC (Y-matched FVC; n=10). Tidal flow-volume loops were recorded during the incremental exercise test with maximal flow-volume loops measured pre- and post-exercise. Compared to younger controls, older adults exhibited more EFL at ventilations of 26, 35, 51, and 80L/min. The older group had higher end-inspiratory lung volume compared to Y-matched%Pred FVC group during submaximal ventilations. The older group increased EELV during exercise, while EELV stayed below resting in the Y-matched%Pred FVC group. These data suggest older adults exhibit more EFL and increase EELV earlier during exercise compared to younger adults. Copyright © 2017 Elsevier B.V. All rights reserved.

    Full Text Available Abstract Background Despite the global decline in death rates of children younger than five years old, the risk of a child dying before turning five years of age remains highest in the WHO African Region. The problem of child death in Ethiopia is worse, with an Ethiopian child being 30 times more likely to die by his/her fifth birthday than a child in Western Europe. Therefore, the aim of this study was to assess the prevalence and factors associated with diarrhea among children younger than five years old. Methods A community-based, cross-sectional study was conducted with mothers who had children younger than five years old from April to June 2014. A multistage sampling procedure was used to select eligible women. The data were coded, entered, cleaned and analyzed with the SPSS software package, version 16. Results he data of 775 mothers were included in the analysis, and 21.5% of the children had diarrhea in the two weeks before the survey. The main factors affecting the occurrence of diarrhea were residence (Odds ratio (AOR = 11.29, 95% Confidence interval (CI: 3.49-36.52, sex (AOR = 2.52, 95% CI:1.28-4.93, methods of complementary feeding (AOR = 50.88, 95% CI: 23.85- 108.54, types of water storage equipment (AOR = 19.50, 95% CI: 8.11-46.90, and cleansing materials used to wash hands (AOR = 5.53, 95% CI: 2.19-13.99. Conclusion Approximately one-fifth of the children included in the study reported diarrheal disease. Residence, sex of the child, type of water storage container, methods of complementary feeding, and cleansing materials to wash the hands were the most important variables that affected the occurrence of diarrhea in children. Therefore, families, the government and nongovernmental organizations working in the area must cooperate in interventions and prevention to minimize the risk of disease.

    Full Text Available Apps promoting patient self-management may improve health outcomes. However, methods to secure stored information on mobile devices may adversely affect usability. We tested the reliability and usability of common user authentication techniques in younger and older adults.Usability testing was conducted in two age groups, 18 to 30 years and 50 years and older. After completing a demographic questionnaire, each participant tested four authentication options in random order: four-digit personal identification number (PIN, graphical password (GRAPHICAL, Android pattern-lock (PATTERN, and a swipe-style Android fingerprint scanner (FINGERPRINT. Participants rated each option using the Systems Usability Scale (SUS.A total of 59 older and 43 younger participants completed the study. Overall, PATTERN was the fastest option (3.44s, and PIN had the fewest errors per attempt (0.02. Participants were able to login using PIN, PATTERN, and GRAPHICAL at least 98% of the time. FINGERPRINT was the slowest (26.97s, had an average of 1.46 errors per attempt, and had a successful login rate of 85%. Overall, PIN and PATTERN had higher SUS scores than FINGERPRINT and GRAPHICAL. Compared to younger participants, older participants were also less likely to find PATTERN to be tiring, annoying or time consuming and less likely to consider PIN to be time consuming. Younger participants were more likely to rate GRAPHICAL as annoying, time consuming and tiring than older participants.On mobile devices, PIN and pattern-lock outperformed graphical passwords and swipe-style fingerprints. All participants took longer to authenticate using the swipe-style fingerprint compared to other options. Older participants also took two to three seconds longer to authenticate using the PIN, pattern and graphical passwords though this did not appear to affect perceived usability.

    The aim of this study is to determine whether physicians have an age bias regarding sexual dysfunction presented by older vs. younger patients in terms of attributed diagnosis, etiology, proposed treatment and perceived prognosis. An on-line survey consisting of one of two, randomly administered, case vignettes, which differed only by the age of the patient (28 or 78). In both cases, the patient was described as suffering from occasional erectile dysfunction with a clear psychosocial indication. A total of 236 physicians responded to the survey. Overall, 110 physicians received an "old" vignette and 126 physicians received a "young" vignette. Even though both cases presented with a clear psychosocial etiology, the "older" vignette was more likely to be diagnosed with erectile dysfunction whereas the "younger" vignette was more likely to be diagnosed with performance anxiety. The "older" vignette's dysfunction was more likely to be attributed to hormonal changes, health problems and decreased sexual desire. Physicians were more likely to recommend testosterone replacement therapy (TRT) and PDE5 inhibitors (PDE5i; such as Sildenafil; Vardenafil; Tadalafil) as well as a referral to urology to the "older" vignette. In contrast, the "younger" vignette was more often referred to a sexologist and received a more positive prognosis than the older patient. This study demonstrates an age bias among physicians regarding sexuality in later life. Of particular note is the tendency to prescribe PDE5i to the older patient, despite the clear psychosocial indication presented in the case vignette. Copyright © 2016 John Wiley & Sons, Ltd.

    Acute diverticulitis has been traditionally associated with worse outcome in young patients, indicating a more aggressive surgical approach is required for them. The aim of this study was to assess whether acute diverticulitis was more virulent in young patients. A retrospective, cross-sectional study included all patients who were admitted for a first episode of acute diverticulitis between January 2004 and December 2013. The patients were divided into two groups (≤50 years and >50 years) based on their age. Patients' characteristics, clinical and surgical data were recorded and analyzed. Overall, 636 patients were included in the database, including 177 (27.8%) in the younger group and 459 in the elder group. There were no significant differences between the groups in disease complexity, peritonitis, laboratory work-up, vital signs on presentation, bowel obstruction or the presence of fistula and abscess in need of drainage. Younger patients had more free extra-luminal air on computed tomography (CT) scan (P = 0.03). Surgical data, including the intra-operative modified Hinchey score and the need for emergency and additional surgery did not significantly differ between the two groups. Young patients had more readmissions (P = 0.01) due to acute diverticulitis, diverticular complications and elective surgery. Length of hospital stay (P = 0.0001) was longer and postoperative complications were more common in the elder patients. The clinical presentation of acute diverticulitis does not seem to be worse in the young population. Younger patients tend to have a more severe presentation on CT scan and more readmissions, but this did not translate to a more severe disease course. © 2016 Chinese Medical Association Shanghai Branch, Chinese Society of Gastroenterology, Renji Hospital Affiliated to Shanghai Jiaotong University School of Medicine and John Wiley & Sons Australia, Ltd.

    Background Injury to the ipsilateral graft used for reconstruction of the anterior cruciate ligament (ACL) or a new injury to the contralateral ACL are disastrous outcomes after successful ACL reconstruction (ACLR), rehabilitation, and return to activity. Studies reporting ACL reinjury rates in younger active populations are emerging in the literature, but these data have not yet been comprehensively synthesized. Purpose To provide a current review of the literature to evaluate age and activity level as the primary risk factors in reinjury after ACLR. Study Design Systematic review and meta-analysis. Methods A systematic review of the literature was conducted via searches in PubMed (1966 to July 2015) and EBSCO host (CINAHL, Medline, SPORTDiscus [1987 to July 2015]). After the search and consultation with experts and rating of study quality, 19 articles met inclusion for review and aggregation. Population demographic data and total reinjury (ipsilateral and contralateral) rate data were recorded from each individual study and combined using random-effects meta-analyses. Separate meta-analyses were conducted for the total population data as well as the following subsets: young age, return to sport, and young age + return to sport. Results Overall, the total second ACL reinjury rate was 15%, with an ipsilateral reinjury rate of 7% and contralateral injury rate of 8%. The secondary ACL injury rate (ipsilateral + contralateral) for patients younger than 25 years was 21%. The secondary ACL injury rate for athletes who return to a sport was also 20%. Combining these risk factors, athletes younger than 25 years who return to sport have a secondary ACL injury rate of 23%. Conclusion This systematic review and meta-analysis demonstrates that younger age and a return to high level of activity are salient factors associated with secondary ACL injury. These combined data indicate that nearly 1 in 4 young athletic patients who sustain an ACL injury and return to high-risk sport

    Cancer fatalism (the belief that death is inevitable when cancer is present) may influence cancer screening practices among older African American women. Little is known about cancer fatalism among younger women. Guided by the Patient/Provider/System Model, this descriptive study compares cancer fatalism and cancer knowledge among African American college students (n = 353) and women from primary care centers (n = 361). Their average age was 29 years. Data were collected using the Powe Fatalism Inventory and breast and cervical cancer knowledge scales. Women at health centers had higher cancer fatalism and lower cancer knowledge. Differences in life experiences may help explain these findings.

    Episodic future thinking (EFT), the ability to project into the future to "preexperience" an event, and prospective memory (PM), remembering to perform an intended action, are both examples of future-oriented cognition. Recently it has been suggested that EFT might contribute to PM performance but to date few studies have examined the relationship between these two capacities. The aim of the present study was to investigate the nature and specificity of this relationship, as well as whether it varies with age. Participants were 125 younger and 125 older adults who completed measures of EFT and PM. Significant, positive correlations between EFT and PM were identified in both age groups. Furthermore, EFT ability accounted for significant unique variance in the young adults, suggesting that it may make a specific contribution to PM function. Within the older adult group, EFT did not uniquely contribute to PM, possibly indicating a reduced capacity to utilize EFT, or the use of compensatory strategies. This study is the first to provide systematic evidence for an association between variation in EFT and PM abilities in both younger and older adulthood and shows that the nature of this association varies as a function of age.

    Most men marry younger women. This has been attributed to men selecting young women due to their high reproductive value and women preferring older men due to their wealth and high social status. Such mate preferences have been suggested to be adaptive, but despite a flourishing number of studies on the mate selection patterns themselves, little is still known of their actual fitness consequences. We examined how the age difference between spouses who married only once affected their lifetime reproductive success in historical monogamous Sami populations. We found that men maximized their fitness by marrying women approximately 15 years younger and vice versa. However, most couples failed to marry optimally. Only 10% of marriages fell within the optimal parental age difference, suggesting that cultural and ecological constraints for maximizing fitness were considerable. Those who succeeded in marrying optimally were the most preferred partners: young women and old men. Our findings indicate that, in Sami, parental age difference was under natural and sexual selection, as suggested by evolutionary theory.

    This study investigated the effects of resistance training (RT) on the metabolism of testosterone (T) in younger (n=5, 28±3yrs.) and older (n=8, 70±2yrs.) men. Experimental heavy resistance exercises (5×10RM leg presses) were performed before and after a 12-month of RT. No age differences were found in the production or metabolic clearance rate of T (determined by stable isotope dilution method), skeletal muscle androgen receptor content or serum LH concentrations due to acute or chronic RT. The T production capacity response to gonadotropin stimulation and the concentrations of the urinary T metabolites (androsterone and etiocholanolone) were lower in the older compared to younger men (pmetabolic clearance rate of T. Attenuated T production capacity and urinary excretion of T metabolites in older men may reflect the known reduction in testicular steroidogenesis upon aging. No changes were observed in T metabolism due to RT indicating a homeostatic stability for this hormone in men of different ages. Copyright © 2015. Published by Elsevier Inc.

    Risk factors for teenage pregnancy are linked to many factors, including a family history of teenage pregnancy. This research examines whether a mother's teenage childbearing or an older sister's teenage pregnancy more strongly predicts teenage pregnancy. This study used linkable administrative databases housed at the Manitoba Centre for Health Policy (MCHP). The original cohort consisted of 17,115 women born in Manitoba between April 1, 1979 and March 31, 1994, who stayed in the province until at least their 20(th) birthday, had at least one older sister, and had no missing values on key variables. Propensity score matching (1:2) was used to create balanced cohorts for two conditional logistic regression models; one examining the impact of an older sister's teenage pregnancy and the other analyzing the effect of the mother's teenage childbearing. The adjusted odds of becoming pregnant between ages 14 and 19 for teens with at least one older sister having a teenage pregnancy were 3.38 (99 % CI 2.77-4.13) times higher than for women whose older sister(s) did not have a teenage pregnancy. Teenage daughters of mothers who had their first child before age 20 had 1.57 (99 % CI 1.30-1.89) times higher odds of pregnancy than those whose mothers had their first child after age 19. Educational achievement was adjusted for in a sub-population examining the odds of pregnancy between ages 16 and 19. After this adjustment, the odds of teenage pregnancy for teens with at least one older sister who had a teenage pregnancy were reduced to 2.48 (99 % CI 2.01-3.06) and the odds of pregnancy for teen daughters of teenage mothers were reduced to 1.39 (99 % CI 1.15-1.68). Although both were significant, the relationship between an older sister's teenage pregnancy and a younger sister's teenage pregnancy is much stronger than that between a mother's teenage childbearing and a younger daughter's teenage pregnancy. This study contributes to understanding of the broader topic "who is

    Full Text Available This study investigated whether age and/or differences in hearing sensitivity influence the perception of the emotion dimensions arousal (calm vs. aroused and valence (positive vs. negative attitude in conversational speech. To that end, this study specifically focused on the relationship between participants’ ratings of short affective utterances and the utterances’ acoustic parameters (pitch, intensity, and articulation rate known to be associated with the emotion dimensions arousal and valence. Stimuli consisted of short utterances taken from a corpus of conversational speech. In two rating tasks, younger and older adults either rated arousal or valence using a 5-point scale. Mean intensity was found to be the main cue participants used in the arousal task (i.e., higher mean intensity cueing higher levels of arousal while mean F0 was the main cue in the valence task (i.e., higher mean F0 being interpreted as more negative. Even though there were no overall age group differences in arousal or valence ratings, compared to younger adults, older adults responded less strongly to mean intensity differences cueing arousal and responded more strongly to differences in mean F0 cueing valence. Individual hearing sensitivity among the older adults did not modify the use of mean intensity as an arousal cue. However, individual hearing sensitivity generally affected valence ratings and modified the use of mean F0. We conclude that age differences in the interpretation of mean F0 as a cue for valence are likely due to age-related hearing loss, whereas age differences in rating arousal do not seem to be driven by hearing sensitivity differences between age groups (as measured by pure-tone audiometry.

    Although much of the lay media attention surrounding sport-related concussion (SRC) focuses on professional athletes, SRC is a common injury in pediatric sports. The anatomy, biomechanics, and response to injury of the developing pediatric brain differ from those of the adult. Similarly, the neurocognitive abilities of the child are developing more rapidly than in an adult. The effects of concussive brain injury on the life of a child are different from those of an adult. This article focuses on the aspects of SRC that are specific to the younger athletes. Copyright © 2011 Elsevier Inc. All rights reserved.

    Recent decision-making work has focused on a distinction between a habitual, model-free neural system that is motivated toward actions that lead directly to reward and a more computationally demanding goal-directed, model-based system that is motivated toward actions that improve one's future state. In this article, we examine how aging affects motivation toward reward-based versus state-based decision making. Participants performed tasks in which one type of option provided larger immediate rewards but the alternative type of option led to larger rewards on future trials, or improvements in state. We predicted that older adults would show a reduced preference for choices that led to improvements in state and a greater preference for choices that maximized immediate reward. We also predicted that fits from a hybrid reinforcement-learning model would indicate greater model-based strategy use in younger than in older adults. In line with these predictions, older adults selected the options that maximized reward more often than did younger adults in three of the four tasks, and modeling results suggested reduced model-based strategy use. In the task where older adults showed similar behavior to younger adults, our model-fitting results suggested that this was due to the utilization of a win-stay-lose-shift heuristic rather than a more complex model-based strategy. Additionally, within older adults, we found that model-based strategy use was positively correlated with memory measures from our neuropsychological test battery. We suggest that this shift from state-based to reward-based motivation may be due to age related declines in the neural structures needed for more computationally demanding model-based decision making.

    Pathological gambling (PG) is a common and costly public health problem associated with impaired quality of life and high suicide rates. Despite its frequency in the general population, PG course is poorly understood in older adults who are especially vulnerable to its devastating consequences. We enrolled 175 subjects in a longitudinal study of gambling behavior: our case group of 53 older adults with PG (≥ 60 years), and two comparison groups including 72 younger adults with PG (Gambling Screen (SOGS) and National Opinion Research Center DSM Screen for Gambling Problems (NODS) scores ≥ 5. Subjects were evaluated at intake and reassessed every 6 months and drop outs were replaced. Follow-up lasted a mean (SD) of 2.6 (1.4) years. At intake older PGs were more likely to be female, Caucasian, divorced, and to have a lower level of education. Older and younger PGs were similar in gambling severity, but older PGs were more likely to have sought PG treatment. Older PGs had lower rates of lifetime drug use disorders, attention deficit/hyperactivity disorder, and obsessive-compulsive disorder. They preferred slots, were more likely to receive PG treatment, and were less likely to discontinue participation in the study. Week by week gambling activity levels showed a significant general downward movement for older and younger PGs, although there were no differences between the groups. Elders without PG had no change in their level of gambling activity. We conclude that younger and older PGs moved toward a reduced level of gambling activity during follow-up. Our data challenge the notion that PG is chronic and progressive. Copyright © 2017 Elsevier B.V. All rights reserved.

    In 2004, the integrated European project GEHA (Genetics of Healthy Ageing) was initiated with the aim of identifying genes involved in healthy ageing and longevity. The first step in the project was the recruitment of more than 2500 pairs of siblings aged 90years or more together with one younger...... composition. From 2004 to 2008 a total of 2535 families comprising 5319 nonagenarian siblings were identified and included in the project. In addition, 2548 younger control persons aged 50-75years were recruited. A total of 2249 complete trios with blood samples from at least two old siblings and the younger...... control were formed and are available for genetic analyses (e.g. linkage studies and genome-wide association studies). Mortality follow-up improves the possibility of identifying families with the most extreme longevity phenotypes. With a mean follow-up time of 3.7years the number of families with all...

    Full Text Available Working memory (WM, a key determinant of many higher-order cognitive functions, declines in old age. Current research attempts to develop process-specific WM training procedures, which may lead to general cognitive improvement. Adaptivity of the training as well as the comparison of training gains to performance changes of an active control group are key factors in evaluating the effectiveness of a specific training program. In the present study, 55 younger adults (20-30 years of age and 45 older adults (60-70 years of age received five weeks of computerized training on various spatial and verbal WM tasks. Half of the sample received adaptive training (i.e., individually adjusted task difficulty, whereas the other half worked on the same task material but on a low task difficulty level (active controls. Performance was assessed using criterion, near-transfer, and far-transfer tasks before training, after 5 weeks of intervention, as well as after a 3-month follow-up interval. Results indicate that (a adaptive training generally led to larger training gains than low-level practice, (b training and transfer gains were somewhat greater for younger than for older adults in some tasks, but comparable across age groups in other tasks, (c far transfer was observed to a test on sustained attention and for a self-rating scale on cognitive functioning in daily life for both young and old, and (d training gains and transfer effects were maintained across the 3-month follow-up interval across age.

  17. Friend or foe? Decoding the facilitative and disruptive effects of emotion on working memory in younger and older adults

    Full Text Available A growing body of work on emotion-cognition interactions has revealed both facilitative and disruptive effects of emotion on working memory in younger adults. These differing effects may vary by the goal relevancy of emotion within a task. Additionally, it is possible that these emotional effects would be larger for older adults, considering findings of preserved emotional processing with age. To test these hypotheses, the current study examined the effects of emotional content and aging on working memory for target information in the presence of distraction. Thirty-six younger (ages 18-29 and 36 older adults (ages 65-87 completed a delayed-response working memory task. Participants viewed two target words intermixed with two distracter words, and then judged whether a subsequently presented probe word was one of the target words. The emotional content (valence and arousal of targets and distracters was systematically manipulated. Results indicated that emotional targets facilitated working memory in both age groups. In contrast, emotional distracters disrupted performance. Negative distracters were particularly disruptive for older adults, but younger adults did not show an emotional interference effect. These findings help clarify discrepancies in the literature and contribute to the sparse research on emotional working memory in older adults.

    Our objective was to investigate the correlations of interdialytic weight gain (IDWG) with the Malnutrition Inflammation Score (MIS) and other nutritional markers, especially when age difference is considered. This was a cross-sectional study. The setting was an outpatient hemodialysis (HD) center in a community hospital. Excluding those with obvious inflammatory diseases, hospitalizations, and major surgery within the preceding 3 months, we enrolled all anuric patients who had undergone maintenance hemodialysis three times a week for >1 year. In total, 84 women and 80 men were enrolled. Their age (mean +/- SD) was 57.9 +/- 13.0 years. The conditions of food intake and nutritional status were evaluated with MIS items. Concerning IDWG, the average of 12 sessions within 4 weeks was used. The relative IDWG (RIDWG) was calculated as IDWG divided by the respective dry weight. Other laboratory data were obtained from routine monthly sampling. Whereas IDWG and RIDWG had no significant correlation with any of the MIS items in younger patients (food intake, gastrointestinal upset, functional incapacity, and wasting of muscle and subcutaneous fat in older patients (>/=65 years old; n = 58). On the other hand, IDWG and RIDWG had no significant correlation with serum albumin level in younger and older HD patients, respectively. Our findings suggest that in older HD patients, the greater that the RIDWG is, the poorer the nutritional status will be. However, there is still controversy regarding IDWG and RIDWG as nutritional markers in HD patients.

    Streptococcus pneumoniae is a leading cause of bacterial pneumonia, meningitis, and sepsis in children worldwide. However, many countries lack national estimates of disease burden. Effective interventions are available, including pneumococcal conjugate vaccine and case management. To support local and global policy decisions on pneumococcal disease prevention and treatment, we estimated country-specific incidence of serious cases and deaths in children younger than 5 years. We measured the burden of pneumococcal pneumonia by applying the proportion of pneumonia cases caused by S pneumoniae derived from efficacy estimates from vaccine trials to WHO country-specific estimates of all-cause pneumonia cases and deaths. We also estimated burden of meningitis and non-pneumonia, non-meningitis invasive disease using disease incidence and case-fatality data from a systematic literature review. When high-quality data were available from a country, these were used for national estimates. Otherwise, estimates were based on data from neighbouring countries with similar child mortality. Estimates were adjusted for HIV prevalence and access to care and, when applicable, use of vaccine against Haemophilus influenzae type b. In 2000, about 14.5 million episodes of serious pneumococcal disease (uncertainty range 11.1-18.0 million) were estimated to occur. Pneumococcal disease caused about 826,000 deaths (582,000-926,000) in children aged 1-59 months, of which 91,000 (63,000-102,000) were in HIV-positive and 735,000 (519,000-825,000) in HIV-negative children. Of the deaths in HIV-negative children, over 61% (449,000 [316,000-501,000]) occurred in ten African and Asian countries. S pneumoniae causes around 11% (8-12%) of all deaths in children aged 1-59 months (excluding pneumococcal deaths in HIV-positive children). Achievement of the UN Millennium Development Goal 4 for child mortality reduction can be accelerated by prevention and treatment of pneumococcal disease, especially in

    We examined how font sizes (18pt., 48 pt.) and font styles (regular, italic, bold) influenced younger and older adults' judgments of learning (JOLs) and recall. In Experiment 1 younger adults gave higher JOLs and obtained higher recall than older adults. However, JOLs and recall varied for both age groups as a function of font size and font style manipulations despite a tendency for both groups to predict higher recall for items in large and in regular and italic styles than for small and bold fonts and achieve higher recall for regular than italic or bold items. No age differences were found in relative accuracy, with near-perfect calibration in absolute accuracy for younger and older adults. Experiment 2 presented a description of Experiment 1 and asked participants to predict recall for the various font size/style combinations. Younger and older adults predicted higher recall for large than small font items, regardless of font style, and higher recall for bold than regular or italic styles, regardless of font size. Memory predictions did not align across experiments, suggesting that memory beliefs combine with processing fluency to affect JOLs and recall.

    Background Similar to many developed countries, vaccination against human papillomavirus (HPV) is provided only to girls in New Zealand and coverage is relatively low (47% in school-aged girls for dose 3). Some jurisdictions have already extended HPV vaccination to school-aged boys. Thus, exploration of the cost-utility of adding boys’ vaccination is relevant. We modeled the incremental health gain and costs for extending the current girls-only program to boys, intensifying the current girls-only program to achieve 73% coverage, and extension of the intensive program to boys. Methods A Markov macro-simulation model, which accounted for herd immunity, was developed for an annual cohort of 12-year-olds in 2011 and included the future health states of: cervical cancer, pre-cancer (CIN I to III), genital warts, and three other HPV-related cancers. In each state, health sector costs, including additional health costs from extra life, and quality-adjusted life-years (QALYs) were accumulated. The model included New Zealand data on cancer incidence and survival, and other cause mortality (all by sex, age, ethnicity and deprivation). Results At an assumed local willingness-to-pay threshold of US$29,600, vaccination of 12-year-old boys to achieve the current coverage for girls would not be cost-effective, at US$61,400/QALY gained (95% UI $29,700 to $112,000; OECD purchasing power parities) compared to the current girls-only program, with an assumed vaccine cost of US$59 (NZ$113). This was dominated though by the intensified girls-only program; US$17,400/QALY gained (95% UI: dominant to $46,100).

    Aerobic fitness and flexibility generally present age-related decreases, yet the influence of age on these variables in soccer players is still unknown. We obtained oxygen consumption (VO(2)) and heart rate (HR) at 12 km · h (- 1), anaerobic threshold and maximum intensities, and athletes' flexibility profiles using Flexitest (FLX). Pre-season data (2005-2011) from the 2 extreme age terciles (n=54) - YOUNGER (17-22 years old) and OLDER (27-36 years old) - of a group of 162 players from an elite Brazilian soccer club were compared. The effects of aging were also assessed by contrasting VO(2), HR and FLX linear regressions - slope and intercept - vs. age-predicted and reference values. The results were similar between the YOUNGER and OLDER terciles for VO(2max), at 62.7 ± 6.1 vs. 63.2 ± 6.2 mL · kg (- 1) · min (- 1), respectively (p=0.67), effect size (ES)=0.08, and for FLX, at 43 ± 5.9 vs. 41 ± 6.0, respectively (p=0.11, ES=0.34); the YOUNGER tercile exhibited higher values for HRmax than the OLDER tercile, at 194 ± 8.1 vs. 189 ± 8.8 b · min (- 1), (page-predicted decrease in VO(2max), whereas HRmax and FLX diminished with age as predicted. We conclude that, at least for these variables, younger and older players were effectively identical in their pre-season levels of conditioning. © Georg Thieme Verlag KG Stuttgart · New York.

    Aging is one of the most important cardiovascular risk factors. Age-related morphologic changes in large resistance vessels include an intima-media-thickening and increased deposition of matrix substance, ultimately leading to a reduced compliance and an increased stiffness of the vessels. Aging of the heart is mainly characterized by an increase of the left ventricular mass in relation to the chamber volume and a decrease of diastolic function. There is some controversy in regard to the question if these changes in the vessel wall are the consequence of aging or if a decrease in physical activity is a major contributor of this process. With age the cardiovascular profile is changing. Whereas smoking is less prominent, arterial hypertension and diabetes mellitus are more often encountered. Primary and secondary prevention through cardiovascular risk factor management is also very important in the aging population due to the increased risk of acute vascular complications with age. Preventive measures have to include life style factor interventions as well as optimized drug therapy. There is no scientific evidence that vascular aging can be prevented by administration of supplements such as antioxidant vitamins. Aspirin is effective for cardiovascular prevention up to a higher age. Betablockers and ACE-inhibitors are generally underused in older patients after myocardial infarctions. Statins are effective in reducing cardiovascular complications up to an age of 80 years. Myocardial infarction in elderly patients is often characterized by atypical symptoms and may be even silent. Interventional therapy in elderly patients is as successful as in younger patients but has an increased complication rate. Ambulatory cardiac rehabilitation in elderly patients leads to significant improvements of physical capacity, well-being and quality of life and may help to prevent social isolation.

    were 51% of the older group who showed evidence of age-related decline on all the motion coherence tasks conducted, with half of these in each the group aged under and over 70 years. Difficulties with noise exclusion failed to explain the sex differences found. The increased number of motion cues present when a larger number of dots were included was sufficient to reduce coherence thresholds in younger women but not older men or women. In addition to age, developmental history and sex may provide further predictors in older individuals of decline on measures of motion discrimination.

    Spatially informative auditory and vibrotactile (cross-modal) cues can facilitate attention but little is known about how similar cues influence visual spatial working memory (WM) across the adult lifespan. We investigated the effects of cues (spatially informative or alerting pre-cues vs. no cues), cue modality (auditory vs. vibrotactile vs. visual), memory array size (four vs. six items), and maintenance delay (900 vs. 1800 ms) on visual spatial location WM recognition accuracy in younger adults (YA) and older adults (OA). We observed a significant interaction between spatially informative pre-cue type, array size, and delay. OA and YA benefitted equally from spatially informative pre-cues, suggesting that attentional orienting prior to WM encoding, regardless of cue modality, is preserved with age.  Contrary to predictions, alerting pre-cues generally impaired performance in both age groups, suggesting that maintaining a vigilant state of arousal by facilitating the alerting attention system does not help visual spatial location WM.

    To evaluate a hand-held portable autorefractor in a pediatric population and compare results with those found on retinoscopy by experienced pediatric retinoscopists. One-hundred and two children aged 5 to 72 months were examined with and without cycloplegia using an autorefractor, and the results compared with those found on standard retinoscopy by two ophthalmologists masked as to the autorefractor findings. Results were converted from conventional notation using plus cylinder to the h-space notation and compared in three-dimensional h-space. There was remarkable agreement between the results found by autorefraction and manual retinoscopy using loose lenses or a phoropter. The findings were similar both for sphere and cylinder across the age ranges studied. The Nikon Retinomax is an accurate instrument to estimate refractive error in children younger than 6 and could prove useful in the office, the operating room, or as a screening device.

    The purpose of this study was to examine the age-related differences in blood pressure, heart rate, and behavioral mood state after caffeine ingestion in younger and older women. Using a placebo-controlled, double-blind design, 10 younger (Y; 18-22 years) and 10 older (O; 50-67 years) healthy women who were moderate consumers of caffeine (self-reported mean intake: Y, 139 +/- 152 mg.day-1; O, 204 +/- 101 mg.day-1) were investigated. All volunteers were characterized for fasting plasma glucose, insulin, free-fatty acids and caffeine levels, body composition, cardiovascular fitness, physical activity, and energy intake. Before and after placebo and caffeine ingestion (5 mg.kg-1 fat-free mass; approximately 208-270 mg) test days, the following variables were measured in all subjects: plasma caffeine levels, heart rate, blood pressure, and behavioral mood state. Results showed that, following caffeine ingestion: (i) both systolic and diastolic blood pressure (SBP and DBP, respectively) increased significantly (p depression decreased (p caffeine ingestion in younger women. In conclusion, blood pressure response is augmented and subjective feelings of behavioral mood state are attenuated to a greater degree in older than in younger women following acute caffeine ingestion. Less physically active younger women are more vulnerable to the pressor response to caffeine than more active younger women. It should be noted that these findings are limited to moderate consumers of caffeine who abstained for 48 h prior to testing, and who ingested caffeine in pill form (approximately 240 mg).

    The present study examined younger and older adults' ability to improve their source memory for different types of sources through imaginal and verbal (sentence) mediators. Younger (18-29 years) and older (60-75 years) adults' strategy use and source memory for either text-type (bold vs italic) or person (woman vs man) sources was assessed; strategy use was either spontaneous or the generation of imaginal mediators was instructed before encoding. Younger and older adults did not differ in spontaneous use of mediator-based strategies; however, older adults generated more images but fewer verbal mediators than younger adults. Participants were able to increase mediator generation when instructed to, resulting in substantial increases in both item and source memory for the instructed conditions in both age groups. Use of verbal mediators was more likely for the more concrete person sources for which source memory was generally better. Importantly, these objective benefits of mediator-based strategies translated into subjective benefits for both younger and older adults: Increased use of either mediator type was correlated with lower experienced task difficulty; the instructions to use imaginal mediators resulted in a significant decrease in difficulty ratings on the group level. Participants were generally able to monitor mediator benefits to both item and source memory and accurately judged mediator strategies (especially imagery) as more effective than repetition; older adults, however, rated all strategies as less effective than younger adults. Implications of these findings, especially for neuropsychological studies on source monitoring, are discussed. Copyright © 2016 Elsevier Ltd. All rights reserved.

    The controversial Younger Dryas impact hypothesis suggests that at the onset of the Younger Dryas an extraterrestrial impact over North America caused a global catastrophe. The main evidence for this impact—after the other markers proved to be neither reproducible nor consistent with an impact—is the alleged occurrence of several nanodiamond polymorphs, including the proposed presence of lonsdaleite, a shock polymorph of diamond. We examined the Usselo soil horizon at Geldrop-Aalsterhut (The Netherlands), which formed during the Allerød/Early Younger Dryas and would have captured such impact material. Our accelerator mass spectrometry radiocarbon dates of 14 individual charcoal particles are internally consistent and show that wildfires occurred well after the proposed impact. In addition we present evidence for the occurrence of cubic diamond in glass-like carbon. No lonsdaleite was found. The relation of the cubic nanodiamonds to glass-like carbon, which is produced during wildfires, suggests that these nanodiamonds might have formed after, rather than at the onset of, the Younger Dryas. Our analysis thus provides no support for the Younger Dryas impact hypothesis. PMID:22547791

    We have reconstructed and calculated the glacier equilibrium line altitudes (ELA) for 120 Younger Dryas palaeoglaciers from Morocco in the south to Svalbard in the north and from Ireland in the west to Turkey in the east. The chronology of these landform were checked and, when derived from cosmogenic dates, these were recalculated based on newer production rates. Frontal moraines/limits for the palaeoglaciers were used to reconstruct palaeoglacier extent by using a GIS tool which implements a discretised solution for the assumption of perfect-plasticity ice rheology for a single flowline and extents this out to a 3D ice surface. From the resulting equilibrium profile, palaeoglaciers palaeo-ELAs were calculated using another GIS tool. Where several glaciers were reconstructed in a region, a single ELA value was generated following the methodology of Osmaston (2005). In order to utilise these ELAs for quantitative palaeo-precipitation reconstructions an independent regional temperature analysis was undertaken. A database of 121 sites was compiled where the temperature was determined from palaeoproxies other than glaciers (e.g. pollen, diatoms, choleoptera, chironimids…) in both terrestrial and offshore environments. These proxy data provides estimates of average annual, summer and winter temperatures. These data were merged and interpolated to generate maps of average temperature for the warmest and coldest months and annual average temperature. From these maps the temperature at the ELA was obtained using a lapse rate of 0.65°C/100m. Using the ELA temperature range and summer maximum in a degree-day model allows determination of the potential melt which can be taken as equivalent to precipitation given the assumption a glacier is in equilibrium with climate. Results show that during the coldest part of the Younger Dryas precipitation was high in the British Isles, the NW of the Iberian Peninsula and the Vosges. There is a general trend for declining precipitation

    There is growing evidence that variability in the size and heat content of the tropical Atlantic Warm Pool impacts circum-North Atlantic climate via the Atlantic Multi-decadal Oscillation mode (Wang et al., 2008). The Atlantic Warm Pool spans the Gulf of Mexico, Caribbean Sea and the western tropical North Atlantic. Barbados is located near the center of the tropical Atlantic Warm Pool and coupled ocean models suggest that Barbados remains near the center of the tropical Atlantic Warm Pool under varying wind stress simulations. Measurements of the oxygen isotope paleothermometer in Acropora palmata coral species recovered from cores offshore Barbados, show a 3oC monotonic decrease in sea surface temperature from 13106 ± 83 to 12744 ± 61 years before present (errors given as 2 sigma). This interval corresponds to a sea level rise from 71.4 meters to 67.1 meters below present levels at Barbados. The 3oC temperature decrease is captured in eight A. palmata specimens that are in stratigraphic sequence, 230Th/234U dated, and analyzed for oxygen isotopes. All measurements are replicated. We are confident that this is the warm pool equivalent of the Younger Dryas climate event. The initiation of this temperature drop in the Atlantic Warm Pool predates the Younger Dryas start in Greenland ice cores, reported to start at 12896 ± 138 years (relative to AD 2000) (Rasmussen et al., 2006), while few other Younger Dryas climate records are dated with similar accuracy to make the comparison.
