    To date, the burden of cancer among young adults has rarely been studied in depth. Our aim was to describe the scale and profile of cancer incidence and mortality worldwide among 20-39 year-olds, highlighting major patterns by age, sex, development level, and geographical region. We did a population-based study to quantify the burden of young adult cancers worldwide. We defined young adult cancers as those occurring between the ages of 20 and 39 years because these individuals will have passed puberty and adolescence, but not yet experienced the effects of hormonal decline, immune response deterioration, or organ dysfunction associated with chronic health conditions. Global, regional, and country-specific (n=184) data estimates of the number of new cancer cases and cancer-associated deaths that occurred in 2012 among young adults were extracted in four 5-year bands from the International Agency for Research on Cancer's GLOBOCAN 2012 for all cancers combined and for 27 major types as defined by the International Classification of Disease, tenth revision. We report the number of new cancer cases and cancer-associated deaths overall and by sex alongside corresponding age-standardised rates (ASR) per 100 000 people per year. We also present results using four levels of the Human Development Index (HDI; low [least developed], medium, high, and very high [most developed]), which is a composite indicator for socioeconomic development comprising life expectancy, education, and gross national income. 975 396 new cancer cases and 358 392 cancer-associated deaths occurred among young adults worldwide in 2012, which equated to an ASR of 43·3 new cancer cases per 100 000 people per year and 15·9 cancer-associated deaths per 100 000 people per year. The burden was disproportionally greater among women and the most common cancer types overall in terms of new cases were female breast cancer, cervical cancer, thyroid cancer, leukaemia, and colorectal cancer; in terms of

    Background: Survivors of teenage and young adult cancer are acknowledged as understudied. Little is known about their long-term adverse health risks, particularly of cardiac disease that is increased in other cancer populations where cardiotoxic treatments have been used. Methods: The Teenage and Young Adult Cancer Survivor Study cohort comprises 200 945 5-year survivors of cancer diagnosed at 15 to 39 years of age in England and Wales from 1971 to 2006, and followed to 2014. Standardized mortality ratios, absolute excess risks, and cumulative risks were calculated. Results: Two thousand sixteen survivors died of cardiac disease. For all cancers combined, the standardized mortality ratios for all cardiac diseases combined was greatest for individuals diagnosed at 15 to 19 years of age (4.2; 95% confidence interval, 3.4–5.2) decreasing to 1.2 (95% confidence interval, 1.1–1.3) for individuals aged 35 to 39 years (2P for trend <0.0001). Similar patterns were observed for both standardized mortality ratios and absolute excess risks for ischemic heart disease, valvular heart disease, and cardiomyopathy. Survivors of Hodgkin lymphoma, acute myeloid leukaemia, genitourinary cancers other than bladder cancer, non-Hodgkin lymphoma, lung cancer, leukaemia other than acute myeloid, central nervous system tumour, cervical cancer, and breast cancer experienced 3.8, 2.7, 2.0, 1.7, 1.7, 1.6, 1.4, 1.3 and 1.2 times the number of cardiac deaths expected from the general population, respectively. Among survivors of Hodgkin lymphoma aged over 60 years, almost 30% of the total excess number of deaths observed were due to heart disease. Conclusions: This study of over 200 000 cancer survivors shows that age at cancer diagnosis was critical in determining subsequent cardiac mortality risk. For the first time, risk estimates of cardiac death after each cancer diagnosed between the ages of 15 and 39 years have been derived from a large population-based cohort with prolonged

    Objective: To evaluate the population immunity to measles and explore the factors associated with measles susceptibility in Yunnan residents aged20 years. Methods: 2 689 residents aged20 years were selected by multistage stratified systematic randomized sampling in 252 villages of 42 counties in Yunnan Province between June and September in 2015. Each subject was surveyed by the same questionnaire, including general information, measles contained vaccine history, measles history, and 5 ml blood sample of each subject was collected. Serum IgG antibodies against measles virus were measured by ELISA. Positive was defined as the antibody concentration ≥250 mU/ml, and negative as <250 mU/ml. Non-conditional logistic regression model was used analyze the factors associated with measles susceptibility in adults. Results: Among 2 689 subjects, 1 214 were males (45.15%), and the overall positive rate of measles IgG antibody was 89.77%. Compared with subjects from the region where economic development was low, subjects from the region where economic development was moderate were likely to be susceptible to measles virus ( OR= 1.81, 95 %CI: 1.33-2.47). Four age groups had higher risk of being susceptible to measles virus (compared with ≥40 years: 20-24 years old, OR= 2.04, 95 %CI: 1.26-3.31; 25-29 years old, OR= 3.72, 95 %CI: 2.37-5.86; 30-34 years old, OR= 1.94, 95 %CI: 1.22-3.09; 35-39 years old, OR= 1.81, 95 %CI: 1.07-3.05). Conclusion: Our results suggest that the serological susceptibility in adults (20-39 years), especially adults from the regions where the economic development was moderate, should be concerned. The additional vaccination strategy targeting young adults is important for reducing the risk of measles infection.

    Zacks, Rose T.; Blanchard-Fields, Fredda; Haley, William E.

    2006-01-01

    This article provides a review of the first 20 years of Psychology and Aging, the American Psychological Association’s first and only scholarly journal devoted to the topic of aging. The authors briefly summarize its history, its contributions to the study of aging, and its broader status as a scholarly publication. One theme highlighted in our review is the diversity of content in the journal throughout its history. Another is the strong impact that articles published in the journal have had on both basic and applied topics in aging. Efforts to encompass the breadth of topics and methodologies in aging research while retaining excellent quality remain the exciting but essential challenge for Psychology and Aging. PMID:16594786

    Background Invasive melanoma of the skin is the third most common cancer diagnosed among adolescents and young adults (aged 15-39 years) in the United States. Understanding the burden of melanoma in this age group is important to identifying areas for etiologic research and in developing effective prevention approaches aimed at reducing melanoma risk. Methods Melanoma incidence data reported from 38 National Program of Cancer Registries and/or Surveillance Epidemiology and End Results statewide cancer registries covering nearly 67.2% of the US population were used to estimate age-adjusted incidence rates for persons 15-39 years of age. Incidence rate ratios were calculated to compare rates between demographic groups. Results Melanoma incidence was higher among females (age-adjusted incidence rates = 9.74; 95% confidence interval 9.62-9.86) compared with males (age-adjusted incidence rates = 5.77; 95% confidence interval 5.68-5.86), increased with age, and was higher in non-Hispanic white compared with Hispanic white and black, American Indians/Alaskan Natives, and Asian and Pacific Islanders populations. Melanoma incidence rates increased with year of diagnosis in females but not males. The majority of melanomas were diagnosed on the trunk in all racial and ethnic groups among males but only in non-Hispanic whites among females. Most melanomas were diagnosed at localized stage, and among those melanomas with known histology, the majority were superficial spreading. Limitations Accuracy of melanoma cases reporting was limited because of some incompleteness (delayed reporting) or nonspecific reporting including large proportion of unspecified histology. Conclusions Differences in incidence rates by anatomic site, histology, and stage among adolescents and young adults by race, ethnicity, and sex suggest that both host characteristics and behaviors influence risk. These data suggest areas for etiologic research around gene-environment interactions and the need for

    2016-11-25

    In 2013-2014, 28.0% of U.S. adults reported that they had told a doctor or other health professional that they had trouble sleeping. A smaller percentage of adults aged 20-39 years (19.2%) reported having trouble sleeping compared with persons aged 40-59 years (32.8%) and ≥60 years (33.2%). This pattern by age group was observed for both men and women, although larger percentages of women aged 40-59 years and ≥60 years reported trouble sleeping compared with men in those age groups.

    When compared with their older counterparts, younger women are more likely to have depressive symptoms because they more often experience interrupted work history and a heavy childrearing burden. The purposes of the present study were 1) to investigate the possible association of psychosocial work environment with psychological distress and 2) to examine the way by which communication and support in the workplace affect to psychological distress among young women. We studied 198 women aged 20 to 39 yr in a cross-sectional study. The Kessler Scale-10 (K10 Scale) was used to examine psychological distress. In employees who experienced interpersonal conflict, those who had little or no conversations with their supervisor and/or co-workers had a significantly increased risk of psychological distress (OR, 4.2), and those who received little or no support from their supervisor and/or co-workers had a significantly increased risk of psychological distress (OR, 3.8) compared to those who had more frequent communication and received more support. Harmonious communication in the workplace can help prevent psychological distress among employees, which in turn may enable them to be satisfied with their work. PMID:26320729

    2016-01-01

    To monitor progress toward maternal and neonatal tetanus elimination (MNTE) in Cambodia, we conducted a nationwide serosurvey of tetanus immunity in 2012. Multistage cluster sampling was used to select 2,154 women aged 15 to 39 years. Tetanus toxoid antibodies in serum samples were measured by gold-standard double-antigen enzyme-linked immunosorbent assay (DAE) and a novel multiplex bead assay (MBA). Antibody concentrations of ≥0.01 IU/ml by DAE or the equivalent for MBA were considered seroprotective. Estimated tetanus seroprotection was 88% (95% confidence interval [CI], 86 to 89%); 64% (95% CI, 61 to 67%) of women had antibody levels of ≥1.0 IU/ml. Seroprotection was significantly lower (P < 0.001) among women aged 15 to 19 years (63%) and 20 to 24 years (87%) than among those aged ≥25 years (96%), among nulliparous women than among parous women (71 versus 97%), and among those living in the western region than among those living in other regions (82 versus 89%). The MBA showed high sensitivity (99% [95% CI, 98 to 99%]) and specificity (92% [95% CI, 88 to 95%]) compared with DAE. Findings were compatible with MNTE in Cambodia (≥80% protection). Tetanus immunity gaps should be addressed through strengthened routine immunization and targeted vaccination campaigns. Incorporating tetanus testing in national serosurveys using MBAs, which can measure immunity to multiple pathogens simultaneously, may be beneficial for monitoring MNTE. PMID:27053629

    We present Ar-40/Ar-39 measurements for twelve small (20-60 micro-g) maskelynite samples from the heavily shocked martian meteorite ALHA 77005. The reported modal composition for ALHA 77005 is 50-60% olivine (Fa28), 30-40% pyroxene (Wo5Fs23En72), approx.8% maskelynite (An53), and approx.2% opaques by volume [1]). The meteorite is usually classified as a lherzolite. Previous Studies - Ar-40/Ar-39 results from previous work display disturbed release spectra [2,3]. In study [2], Ar-40/Ar-39 measurements on a 52-mg whole-rock sample produced an extremely disturbed release spec-trum, with all calculated apparent ages > 1 Ga, (Fig. 1). In a subsequent study [3], a light and a dark phase were analyzed. A 2.3-mg sample of the light, relatively low-K phase produced a disturbed release spectrum. For the first 20% of the Ar-39(sub K), most of the apparent ages exceeded >1 Ga; the remaining 80% yielded ages between 0.3-0.5 Ga. The integrated age for this phase is 0.9 Ga.

    2013-07-01

    The lower limbs of children aged 3-9 years present varying knock-knee deformities that have a direct impact on the diversification of the load-bearing axis of the valgus limb and on the modification of gait kinematics. The purpose of our study was to establish the reference values of knee alignment in a Greek population and whether this is linked to a change in the physical activity of children depending on the severity of the genu valgum. Using a clinical method, we measured both the tibiofemoral (TF) angle and the intermalleolar (IM) distance of the lower extremities of normal children. Subsequently, forms of the Netherlands Physical Activity Questionnaire (NPAQ) for young children and the Baecke questionnaire on habitual physical activity, modified especially for children, were completed by the parents. We examined both the development of the TF angle and the IM distance in relation to age and the degree of restriction of physical activity in relation to the severity of the genu valgum. We analysed 316 unaffected lower extremities in children aged 3-9 years. The average value of the TF angle starts around 7° at the age of 3 years and gradually decreases to 4° at the age of 7-8 years. The average value of the IM distance ranges over 3.5 cm at the age of 3 years and progressively decreases to 2 cm at the age of 7-8 years. Physical activity appears to be influenced by sex and the severity of the genu valgum. We provide age-specific values for limb alignment and joint orientation of the lower extremity in children aged 3-9 years. A statistical correlation between all indexes (sport, leisure time and total) of the Baecke and the NPAQs and measurements of genu valgum was noted depending on the severity of the valgus deformity.

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

    North-West-Africa 3171 is a 506 g, relatively fresh appearing, basaltic shergottite with similarities to Zagami and Shergotty, but not obviously paired with any of the other known African basaltic shergottites. Its exposure age has the range of 2.5-3.1 Myr , similar to those of Zagami and Shergotty. We made AR-39-AR-40 analyses of a "plagioclase" (now shock-converted to maskelynite) separate and of a glass hand-picked from a vein connected to shock melt pockets.. Plagioclase was separated using its low magnetic susceptibility and then heavy liquid with density of <2.85 g/cm(exp 3). The AR-39-AR-40 age spectrum of NWA-317 1 plag displays a rise in age over 20-100% of the 39Ar release, from 0.24 Gyr to 0.27 Gy.

    To examine the relationship between major depression and insulin resistance by gender and race/ethnicity among young adults without diabetes mellitus. Secondary analyses of cross-sectional data from the National Health and Nutrition Examination Survey 1999-2008 were performed (n = 2265). Major depression was measured by the Composite International Diagnostic Interview and the Patient Health Questionnaire 9. Insulin resistance was measured by the homeostasis model assessment of insulin resistance. Multivariate logistic regression analyses adjusted for risk factors of insulin resistance were conducted. There was a significant negative association between major depression and insulin resistance among men. For women, no significant association was found. There was no significant interaction between race/ethnicity and major depression on insulin resistance (Wald χ(2) = 4.2927, P = 0.2315). Body mass index (BMI) and waist circumference (WC) were significantly associated with insulin resistance among both men (odds ratio [OR] 1.255, 95% confidence interval [CI] 1.195-1.318 for BMI; OR 1.095, 95% CI 1.076-1.115 for WC) and women (OR 1.220, 95% CI 1.182-1.260 for BMI; OR 1.084, 95% CI 1.064-1.105 for WC). There are gender differences in the relationship between major depression and insulin resistance among adults aged 20-39 years. No evidence was found to support the role of race/ethnicity in this relationship. Health care professionals should be aware of risk factors for insulin resistance and develop interventions to help prevent the progression of insulin resistance to type 2 diabetes mellitus. © 2013 Ruijin Hospital, Shanghai Jiaotong University School of Medicine and Wiley Publishing Asia Pty Ltd.

    1992-01-01

    Ar-40/Ar-39 dating of drill-core samples of a glassy melt rock recovered from beneath a massive impact breccia contained with the 180-kilometer subsurface Chicxulub crater yields well-behaved incremental heating spectra with a mean plateau age of 64.98 +/- 0.05 million years ago (Ma). The glassy melt rock of andesitic composition was obtained from core 9 (1390 to 1393 meters) in the Chicxulub 1 well. The age of the melt rock is virtually indistinguishable from Ar-40/Ar-39 ages obtained on tektite glass from Beloc, Haiti, and Arroyo el Mimbral, northeastern Mexico, of 65.01 +/- 0.08 Ma (mean plateau age for Beloc) and 65.07 +/- 0.10 Ma (mean total fusion age for both sites). The Ar-40/Ar-39 ages, in conjunction with geochemical and petrological similarities, strengthen the suggestion that the Chicxulub structure is the source for the Haitian and Mexican tektites and is a viable candidate for the Cretaceous-Tertiary boundary impact site.

  15. Routine Eye Examinations for Persons 20-64 Years of Age

    PubMed Central

    2006-01-01

    - stage (early ARM) and a late-stage (AMD). AMD is the leading cause of blindness in developed countries. The prevalence of AMD increases with increasing age. It is estimated that 1% of people 55 years of age, 5% aged 75 to 84 years and 15% 80 years of age and older have AMD. ARM can be diagnosed during fundoscopy (ophthalmoscopy) which is a visual inspection of the retina by a physician or optometrist, or from a photograph of the retina. There is no cure or prevention for ARM. Likewise, there is currently no treatment to restore vision lost due to AMD. However, there are treatments to delay the progression of the disease and further loss of vision. The Technology A periodic oculo-visual assessment is defined “as an examination of the eye and vision system rendered primarily to determine if a patient has a simple refractive error (visual acuity assessment) including myopia, hypermetropia, presbyopia, anisometropia or astigmatism.” This service includes a history of the presenting complaint, past medical history, visual acuity examination, ocular mobility examination, slit lamp examination of the anterior segment, ophthalmoscopy, and tonometry (measurement of IOP) and is completed by either a physician or an optometrist. Review Strategy The Medical Advisory Secretariat conducted a computerized search of the literature in the following databases: OVID MEDLINE, MEDLINE, In-Process & Other Non-Indexed Citations, EMBASE, INAHTA and the Cochrane Library. The search was limited to English-language articles with human subjects, published from January 2000 to March 2006. In addition, a search was conducted for published guidelines, health technology assessments, and policy decisions. Bibliographies of references of relevant papers were searched for additional references that may have been missed in the computerized database search. Studies including participants 20 years and older, population-based prospective cohort studies, population-based cross-sectional studies when

  16. Change in Body Weight from Age 20 Years Is a Powerful Determinant of the Metabolic Syndrome.

    PubMed

    Higher body weight is a well-known determinant of the metabolic syndrome (MetS) and its components. It is however less well studied how the change in weight from age 20 years to middle age or old age affects MetS development. In the community-based EpiHealth (n = 19,000, age range 45 to 75 years, 56% females) and PIVUS (n = 1000, all aged 70 years, 50% females) studies, the participants were asked about their body weight at age 20 years. Data were collected to determine MetS prevalence (NCEP ATP III criteria). In EpiHealth, the probability of having MetS increased fairly linearly with increasing weight from age 20 in the obese [odds ratios (OR) 1.04 per kg change in weight, 95% confidence interval (CI) 1.03-1.05, P < 0.0001], as well as in the overweight (OR 1.15, 95% CI 1.14-1.17, P < 0.0001) and normal-weight (OR 1.18, 95% CI 1.14-1.21, P < 0.0001), subjects after adjustment for age, sex, body mass index (BMI) at age 20, alcohol intake, smoking, education, and exercise habits. Also in the PIVUS study, the change in weight over 50 years was related to prevalent MetS (OR 1.08 per kg change in weight, 95% CI 1.06-1.10, P < 0.0001). In both studies, self-reported BMI at age 20 was related to prevalent MetS. Self-reported weight gain from age 20 was strongly and independently associated with prevalent MetS both in middle age or old age. Interestingly, this relationship was not restricted only to obese subjects. Our data provide additional support for the importance of maintaining a stable weight throughout life.

  17. Biological aging and physical fitness in men aged 20-70 years from Kraków, Poland.

    PubMed

    Gołąb, Stanisław; Woronkowicz, Agnieszka; Kryst, Łukasz

    2016-07-01

    The increasing problem of population aging requires appropriate economic and health-related measures to mitigate its negative effects. The aim was to categorize the biological age of men between 20 and 70 years of age and assess its relationship to their physical activity and fitness. Data included morphological variables, total body water, the results of five Eurofit motor tests and the percentage of maximum heart rate (HR%), during a cardiovascular test of more than 1,400 20-70 year-old men living in Kraków. Biological age was estimated with regression equations. There were significant and consistent differences in physical fitness profiles between the three established groups of relations between biological and chronological age (biologically younger, equal, and older). These three categories of biological age were generally consistent with the regression analysis of physical fitness results, although declared physical activity seemed to be an independent factor. The selected morphological variables represent a set of characteristics useful for the determination of the biological age. The existing relationship between physical activity and biological age indicates that physical activity may contribute to the inhibition of involutional changes, even if it had only been performed regularly in the past.

  3. Comparative study of millennials' (age 20-34 years) grip and lateral pinch with the norms.

    PubMed

    Fain, Elizabeth; Weatherford, Cara

    Cross-sectional research design. Clinical practice continues to use normative data for grip and pinch measurements that were established in 1985. There is no updated norms despite different hand usage patterns in today's society. Measuring and comparing grip and pinch strengths with normative data is a valid method to determine hand function. This research was implemented to compare the grip and pinch measurements obtained from healthy millennials to the established norms and to describe hand usage patterns for millennials. Grip and lateral pinch measurements were obtained from a sample of 237 healthy millennials (ages 20-34 years). Strength scores were statistically lower that older normative data in all millennial grip strengths, with the exception of the women in the age group of 30-34 years. Specifically, this statistically significant trend was observed in all male grip strengths, as well as in women in the age group of 20-24 years (bilateral grip) and 25-29 years (right grip). However, the lateral pinch data reflected was similar to the older norms with variances of 0.5-1 kg. Current data reflect statistically significant differences from the norms for all male grip measurements, as well as for women in the age group of 20-24 years (bilateral grip) and 25-29 years (right grip). No statistical significance was observed in the independent-sample t tests for the lateral pinch in men of all age groups. Statistical significance was noted for lateral pinch for female age groups for the left hand (20-24 years) and for bilateral lateral pinches (30-34 years). IV. Copyright © 2016 Hanley & Belfus.

  10. Greater short-term weight loss in women 20-45 versus 55-65 years of age following bariatric surgery.

    Ochner, Christopher N; Teixeira, Julio; Geary, Nori; Asarian, Lori

    2013-10-01

    Whether and how sex and age affect bariatric-surgery outcome is poorly understood. Estrogens regulate body composition in women and animals, and increase weight loss in a rodent model of gastric bypass, suggesting that premenopausal women may lose more weight following bariatric surgery. One thousand three hundred fifty-six female gastric-bypass or gastric-banding patients were retrospectively grouped as 20-45 years old (presumptively premenopausal; n = 1,199) and 55-65 years old (presumptively postmenopausal; n = 157). Mixed-model ANCOVA followed by Bonferroni-corrected t tests were used to categorically test the effect of age on percent excess body weight loss (%EBWL) at 1 and 2 years post-surgery, controlling for preoperative EBW and surgery type. Age effects were also tested dimensionally in all women and in 289 male patients. Twenty- to forty-five-year-old women showed greater %EBWL 1 and 2 years post-surgery than 55-65-year-old women (p's < 0.0005). No age effect was detected in 20-25- vs. 30-35-, 30-35- vs. 40-45-, or 20-25- vs. 40-45-year-old women (p's > 0.2) This age effect was detected only after gastric banding, with 20-45-year-old women losing ∼7 kg more than 55-65-year-old women after 2 years. Dimensional analysis confirmed a significant inverse effect of age on bariatric surgery outcome in women, but did not detect any effect in men. Results indicate that 55-65-year-old women lose less weight than 20-45-year-old women in the initial 2 years after bariatric surgery, especially gastric banding; this may be mediated by age- or menopause-associated changes in physical activity, energy expenditure, or energy intake.

  11. Methods for using argon-39 to age-date groundwater using ultra-low-background proportional counting

    Mace, Emily; Aalseth, Craig; Brandenberger, Jill

    Argon-39 can be used as a tracer for age-dating glaciers, oceans, and more recently, groundwater. With a half-life of 269 years, 39Ar fills an intermediate age range gap (50-1,000 years) not currently covered by other common groundwater tracers. Therefore, adding this tracer to the data suite for groundwater studies provides an important tool for improving our understanding of groundwater systems. We present the methods employed for arriving at an age-date for a given sample of argon degassed from groundwater.

    2017-07-06

    Objective: To determine the basal metabolic rate (BMR) of young adults aged between 20-29 years old in Changsha. Methods: We recruited volunteers to join in our research project from April to May, 2015. All recruited volunteers must meet the inclusion criteria: aged 20-29 years old, height between 164-180 centimeters in males and 154-167 centimeters in females, in good health condition, and with no habit of regular physical exercise in last year. Finally, 81 qualified volunteers were selected as research objects, including 43 males and 38 females. The BMR, resting lying metabolism rate and resting sitting metabolism rate of the subjects were detected, and the determined BMR was compared with the calculated results: from the adjusted Schofield equation. Results The BMR, resting lying metabolism rate and resting sitting metabolism rate among males were (166.10±22.09), (174.22±24.56), and (179.54±23.35) kJ·m(-2)·h(-1), respectively, which were all higher than those among females were (137.70±20.04), (149.79±19.25), and (167.78±26.02) kJ·m(-2)·h(-1), respectively, ( P< 0.001). The BMR of males and females calculated from the adjusted Schofield equation were (160.83±3.93), and (140.29±4.18) kJ·m(-2)·h(-1), respectively, and there was no significantly statistical difference found between the determined BMR and the calculated results from Schofield equation (adjusted) classified by sex, all P values >0.05. Conclusion: The BMR of young adults aged 20-29 years old in Changsha was in the national average level, and the adjusted Schofield equation displayed fine accuracy in predicting BMR of young adults aged 20-29 years old in Changsha.

    The Italian volcano, Vesuvius, erupted explosively in AD 79. Sanidine from pumice collected at Casti Amanti in Pompeii and Villa Poppea in Oplontis yielded a weighted-mean 40Ar/39Ar age of 1925±66 years in 2004 (1σ uncertainty) from incremental-heating experiments of eight aliquants of sanidine. This is the calendar age of the eruption. Our results together with the work of Renne et al. (1997) and Renne and Min (1998) demonstrate the validity of the 40Ar/39Ar method to reconstruct the recent eruptive history of young, active volcanoes.

  19. Ar-40/Ar-39 ages and cosmic ray exposure ages of Apollo 14 samples.

    1971-01-01

    We have used the Ar-40/Ar-39 dating technique on eight samples of Apollo 14 rocks (14053, 14310), breccia fragments (14321), and soil fragments (14001, 14167). The large basalt fragments give reasonable Ar-40/Ar-39 release patterns and yield well defined crystallization ages of 3.89-3.95 aeons. Correlation of the Ar-40/Ar-39 release patterns with Ar-39/Ar-37 patterns showed that the low temperature fractions with high radiogenic argon loss came from K-rich phases. A highly shocked sample and fragments included in the breccia yield complex release patterns with a low temperature peak. The total argon age of these fragments is 3.95 aeons. Cosmic ray exposure ages on these samples are obtained from the ratio of spallogenic Ar-38 to reactor induced Ar-37 and show a distinct grouping of low exposure ages of 26 m.y. correlated with Cone crater. Other samples have exposure ages of more than 260 m.y. and identify material with a more complex integrated cosmic age exposure history.

Sanidine from pumice collected at Casti Amanti in Pompeii and Villa Poppea in Oplontis yielded a weighted-mean 40Ar/39Ar age of 1925±66 years in 2004 (1σ uncertainty) from incremental-heating experiments of eight aliquants of sanidine. This is the calendar age of the eruption. Our results together with the work of Renne et al. (1997) and Renne and Min (1998) demonstrate the validity of the 40Ar/39Ar method to reconstruct the recent eruptive history of young, active volcanoes.

    The lack of longitudinal data analyses from birth to adulthood is hampering long-term asthma prevention strategies. We aimed to determine early-life predictors of asthma incidence up to age 20 years in a birth cohort study by applying time-to-event analysis. In 1990, the Multicenter Allergy Study included 1314 newborns in 5 German cities. Children were evaluated from birth to age 20 years at 19 time points. Using a Cox regression model, we examined the associations between 36 early-life factors and onset of asthma based on a doctor's diagnosis or asthma medication (primary outcome), typical asthma symptoms, or allergic asthma (including positive IgE measurements). Response at 20 years was 71.6%. Two hundred eighteen subjects met the primary outcome criteria within 16,257 person years observed. Asthma incidence was lower in participants who were vaccinated (measles, mumps, and rubella vaccine/tick-borne encephalitis vaccine/BCG vaccine: adjusted hazard ratio [HR], 0.66 [95% CI, 0.47-0.93]). Up to age 20 years, asthma incidence was higher in subjects who had parents with allergic rhinitis (adjusted HR, 2.24 [95% CI, 1.67-3.02]), started day care early or late (before 18 months: adjusted HR, 1.79 [95% CI, 1.03-3.10]; after 3 years: adjusted HR, 1.64 [95% CI, 0.96-2.79]), had mothers who smoked during pregnancy (adjusted HR, 1.79 [95% CI, 1.20-2.67]), had poor parents (adjusted HR, 1.55 [95% CI, 1.09-2.22]), and had parents with asthma (adjusted HR, 1.65 [95% CI, 1.17-2.31]). Not associated with asthma were aspects of diet and breast-feeding, pet ownership, presence of older siblings, and passive smoking. Parental asthma and nasal allergy increase asthma incidence in offspring up to adulthood. Avoiding tobacco smoke exposure during pregnancy, receiving vaccinations in early childhood, and starting day care between 1.5 and 3 years of age might prevent or delay the development of asthma.

  13. The effects of age and gender on sleep EEG power spectral density in the middle years of life (ages 20-60 years old)

    NASA Technical Reports Server (NTRS)

    Carrier, J.; Land, S.; Buysse, D. J.; Kupfer, D. J.; Monk, T. H.

    2001-01-01

    The effects of age and gender on sleep EEG power spectral density were assessed in a group of 100 subjects aged 20 to 60 years. We propose a new statistical strategy (mixed-model using fixed-knot regression splines) to analyze quantitative EEG measures. The effect of gender varied according to frequency, but no interactions emerged between age and gender, suggesting that the aging process does not differentially influence men and women. Women had higher power density than men in delta, theta, low alpha, and high spindle frequency range. The effect of age varied according to frequency and across the night. The decrease in power with age was not restricted to slow-wave activity, but also included theta and sigma activity. With increasing age, the attenuation over the night in power density between 1.25 and 8.00 Hz diminished, and the rise in power between 12.25 and 14.00 Hz across the night decreased. Increasing age was associated with higher power in the beta range. These results suggest that increasing age may be related to an attenuation of homeostatic sleep pressure and to an increase in cortical activation during sleep.

  14. Astronomically calibrated 40Ar/39Ar age for the Toba supereruption and global synchronization of late Quaternary records

    The Toba supereruption in Sumatra, ∼74 thousand years (ka) ago, was the largest terrestrial volcanic event of the Quaternary. Ash and sulfate aerosols were deposited in both hemispheres, forming a time-marker horizon that can be used to synchronize late Quaternary records globally. A precise numerical age for this event has proved elusive, with dating uncertainties larger than the millennial-scale climate cycles that characterized this period. We report an astronomically calibrated 40Ar/39Ar age of 73.88 ± 0.32 ka (1σ, full external errors) for sanidine crystals extracted from Toba deposits in the Lenggong Valley, Malaysia, 350 km from the eruption source and 6 km from an archaeological site with stone artifacts buried by ash. If these artifacts were made by Homo sapiens, as has been suggested, then our age indicates that modern humans had reached Southeast Asia by ∼74 ka ago. Our 40Ar/39Ar age is an order-of-magnitude more precise than previous estimates, resolving the timing of the eruption to the middle of the cold interval between Dansgaard–Oeschger events 20 and 19, when a peak in sulfate concentration occurred as registered by Greenland ice cores. This peak is followed by a ∼10 °C drop in the Greenland surface temperature over ∼150 y, revealing the possible climatic impact of the eruption. Our 40Ar/39Ar age also provides a high-precision calibration point for other ice, marine, and terrestrial archives containing Toba sulfates and ash, facilitating their global synchronization at unprecedented resolution for a critical period in Earth and human history beyond the range of 14C dating.

    2014-01-01

    Background Obesity increases risk of premature disease, and may be associated with unfavorable lifestyle changes that add to risk. This study analyzed the association of midlife BMI change with current lifestyle patterns among multiethnic men. Methods Men aged 40-60 years (n=9864) retrospectively reported body weight between ages 20-40 years and current dietary, TV, physical activity and sleep practices in the Adventist Health Study II, a study of church-goers in the US and Canada. In multivariate logistic regression analysis, odds ratios for BMI gain were calculated for each lifestyle practice controlling for sociodemographic and other lifestyle factors and current BMI. Results Men with median or higher BMI gain (2.79 kg/m2) between ages 20-40 years were more likely to consume a non-vegetarian diet, and engage in excessive TV watching and little physical activity and had a shorter sleep duration compared to men with BMI gain below the median (all p<0.001). In multivariate logistic analysis current BMI was significantly associated with all lifestyle factors in multivariate analyses (all p≤0.005). BMI gain was associated with lower odds of vegetarian diet (odds ratio [OR] 0.939; 95% confidence interval [CI] 0.921-0.957) and of physical activity ≥150 minutes/week (OR 0.979, 95% CI 0.960-0.999). Conclusions These findings imply that diet and less physical activity are associated with both gained and attained BMI, while inactivity (TV watching) and short sleep duration correlated only with attained BMI. Unhealthy lifestyle may add risk to that associated with BMI. Longitudinal and intervention studies are needed to infer causal relationships. PMID:25434910

    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.

  19. Polyfluoroalkyl Chemicals and Menopause among Women 20–65 Years of Age (NHANES)

    PubMed Central

    Hoffman, Kate; Thayer, Kristina A.; Daniels, Julie L.

    2013-01-01

    Background: Polyfluoroalkyl chemicals (PFCs) such as perfluorooctane sulfonate (PFOS) and perfluorooctanoate (PFOA) have been associated with early menopause. However, previous cross-sectional studies have lacked adequate data to investigate possible reverse causality (i.e., higher serum concentrations due to decreased excretion after menopause). Objectives: We investigated the association between PFOS, PFOA, perfluorononanoate (PFNA), and perfluorohexane sulfonate (PFHxS) and age at natural menopause among women 20–65 years of age in NHANES (National Health and Nutrition Examination Survey). Methods: We used proportional hazard models to estimate hazard ratios (HRs) for the onset of natural menopause as a function of age and serum PFC levels, and to investigate reverse causation by estimating associations between PFC levels and the rate of hysterectomy. We also used multivariable linear regression to determine whether time since menopause predicted serum PFC levels. Results: After adjusting for age at survey, race/ethnicity, education, ever smoking, and parity, women with higher levels of PFCs had earlier menopause than did women with the lowest PFC levels. We observed a monotonic association with PFHxS: The HR was 1.42 (95% CI: 1.08, 1.87) for serum concentrations in tertile 2 versus tertile 1, and 1.70 (95% CI: 1.36, 2.12) for tertile 3 versus tertile 1. We also found evidence of reverse causation: PFCs were positively associated with rate of hysterectomy, and time since natural menopause was positively associated with serum PFCs. Conclusions: Our findings suggest a positive association between PFCs and menopause; however, at least part of the association may be due to reverse causation. Regardless of underlying cause, women appear to have higher PFC concentrations after menopause. Citation: Taylor KW, Hoffman K, Thayer KA, Daniels JL. 2014.

    The prevalence of obesity in long-term survivors with complex congenital heart disease may be increasing, and little is known about the timing and onset of weight gain and growth patterns in these high-risk patients. Prevalence rates of overweight/obesity and longitudinal changes in body mass index (BMI) with age were determined in 606 patients with Fontan circulation seen at a tertiary care cardiology center from 1992 to 2012. The number of clinic encounters (n) was stratified by age group (n = 401, 2-5 years; n = 333, 6-11 years; n = 217, 12-19 years; and n = 129, >20 years). Among adults, 39% were overweight/obese at last clinic visit; 22% overweight, and 17% obese. Childhood anthropometric data were available for 82 adults, of which 15% (n = 12/82) were overweight/obese in childhood. The likelihood of being overweight/obese as an adult was three times higher if there was a BMI ≥ 85th percentile in childhood (CI 2.1-4.5, P < 0.01). Overweight/obesity in adulthood was associated with lower heart failure rates (4 vs. 19%, P = 0.03). Pediatric rates of overweight/obesity were comparable to national data (NHANES 2011-2012) in every age group: at 2-5 years, (25 vs. 23%), 6-11 years (26 vs. 34%), and 12-19 years (15 vs. 35%). Systolic blood pressure was higher in overweight/obese children as young as 2-5 years of age. Childhood and adult survivors with Fontan circulation have high rates of overweight/obesity. Childhood obesity is a strong predictor of future adiposity and is linked to changes in systolic blood pressure at a very young age.

  2. An evaluation of the effect of Ohio's graduated driver licensing law on motor vehicle crashes and crash outcomes involving drivers 16 to 20 years of age.

    PubMed

    Nationally, motor vehicle crashes are the leading cause of death among youth ages 16 to 20 years. Graduated driver licensing (GDL) laws have been implemented to reduce motor vehicle crashes among teen drivers. Studies have shown decreases in teen crash rates and crash-related fatality rates following enactment of GDL laws. However, GDL laws typically apply to teens only until their 18th birthday; therefore, the effect, if any, that GDL laws have on youth drivers ages 18 to 20 years and whether these programs should be extended to include these older youth warrant further study. The objective of this study was to evaluate the effects of Ohio's 2007 revised GDL law on motor vehicle crashes and crash-related injuries for crashes involving teen drivers ages 16 to 20 years, with a focus on the effects on crashes involving drivers ages 18 to 20 years. Cross-sectional analysis of motor vehicle crashes involving drivers ages 16 to 20 years in Ohio in the pre-GDL (2004-2006) and post-GDL (2008-2010) periods was performed. Descriptive statistics and population-based crash rates for drivers and occupants ages 16 to 20 years were calculated, as well as rate ratios and 95% confidence intervals (CIs) comparing crashes in the pre-GDL and post-GDL periods. Compared with the pre-GDL period, the post-GDL period was associated with lower crash rates for drivers age 16 years (relative risk [RR] = 0.94; 95% CI, 0.90-0.98), age 17 years (RR = 0.90; 95% CI, 0.88-0.93), age 18 years (RR = 0.95; 95% CI, 0.92-0.97), and ages 16-17 years combined (RR = 0.92; 95% CI, 0.90-0.95). Crash rate was higher for the post-GDL period for drivers age 19 years (RR = 1.04; 95% CI, 1.01-1.07), age 20 years (RR = 1.09; 95% CI, 1.05-1.13), and ages 18-20 years combined (RR = 1.02; 95% CI, 1.00-1.03). Unlike previous studies, this investigation used linked data to evaluate the outcomes of all occupants in crashes involving drivers ages 16-20 years. The post-GDL period was associated with lower

    Background Schistosomiasis is a water-based disease that is believed to affect over 200 million people with an estimated 97% of the infections concentrated in Africa. However, these statistics are largely based on population re-adjusted data originally published by Utroska and colleagues more than 20 years ago. Hence, these estimates are outdated due to large-scale preventive chemotherapy programs, improved sanitation, water resources development and management, among other reasons. For planning, coordination, and evaluation of control activities, it is essential to possess reliable schistosomiasis prevalence maps. Methodology We analyzed survey data compiled on a newly established open-access global neglected tropical diseases database (i) to create smooth empirical prevalence maps for Schistosoma mansoni and S. haematobium for individuals aged20 years in West Africa, including Cameroon, and (ii) to derive country-specific prevalence estimates. We used Bayesian geostatistical models based on environmental predictors to take into account potential clustering due to common spatially structured exposures. Prediction at unobserved locations was facilitated by joint kriging. Principal Findings Our models revealed that 50.8 million individuals aged20 years in West Africa are infected with either S. mansoni, or S. haematobium, or both species concurrently. The country prevalence estimates ranged between 0.5% (The Gambia) and 37.1% (Liberia) for S. mansoni, and between 17.6% (The Gambia) and 51.6% (Sierra Leone) for S. haematobium. We observed that the combined prevalence for both schistosome species is two-fold lower in Gambia than previously reported, while we found an almost two-fold higher estimate for Liberia (58.3%) than reported before (30.0%). Our predictions are likely to overestimate overall country prevalence, since modeling was based on children and adolescents up to the age of 20 years who are at highest risk of infection.

    To report successful therapy for anisometropic and strabismic amblyopia initiated after age 7 years. A consecutive series of 36 compliant children older than 7 years (range, 7.0 to 10.3 years; mean, 8.2 years) at initiation of amblyopia therapy for anisometropic (19 patients; mean age, 8.3 years), strabismic (9 patients; mean age, 8.0 years), or anisometropic and strabismic (8 patients; mean age, 8.0 years) amblyopia was studied. Initial (worst) visual acuities were between 20/50 and 20/400 (log geometric mean, -0.83 [antilog, 20/134] for all patients; -0.88 [antilog, 20/151] for anisometropic patients; -0.70 [antilog, 20/100] for strabismic patients; and -0.88 [antilog, 20/151] for anisometropic and strabismic patients). Initial (worst) binocularity was absent or reduced in all cases. Therapy consisted of (1) full-time standard occlusion (21 patients; mean age, 8.0 years), (2) total penalization (7 patients; mean age, 7.8 years), or (3) full-time occlusive contact lenses (8 patients; mean age, 8.8 years). Final (best) visual acuities were between 20/20 and 20/30 for all 36 patients. Final (best) binocularity was maintained or improved for 22 (61%) of 36 patients, including 16 anisometropic patients (84%), 2 strabismic patients (22%), and 4 anisometropic and strabismic patients (50%). Given compliance, therapy for anisometropic and strabismic amblyopia can be successful even if initiated after age 7 years. Arch Ophthalmol. 2000;118:1535-1541

    Introduction Young adults with hyperlipidemia, hypertension, and diabetes are at increased risk of developing heart disease later in life. Despite emphasis on early screening, little is known about awareness of these risk factors in young adulthood. Methods Data from the nationally representative cross-sectional survey National Health and Nutrition Examination Survey 2011–2014 were analyzed in 2017 to estimate the prevalence of self-reported awareness of hypercholesterolemia, hypertension, and diabetes in U.S. young adults aged 18–39 years (n=11,083). Prevalence estimates were weighted to population estimates using survey procedures, and predictors of awareness were identified using weighted logistic regression. Results Among U.S. young adults, the prevalence of hypercholesterolemia, hypertension, and diabetes was 8.8% (SE=0.4%), 7.3% (SE=0.3%), and 2.6% (SE=0.2%), respectively. The prevalence of borderline high cholesterol, blood pressure, and blood glucose were substantially higher (21.6% [SE= 0.6%], 26.9% [SE=0.7%], and 18.9% [SE=0.6%], respectively). Awareness was low for hypercholesterolemia (56.9% [SE=2.4%]) and moderate for hypertension and diabetes (62.7% [SE=2.4%] and 70.0% [SE=2.7%]); <25% of young adults with borderline levels of these risk factors were aware of their risk. Correlates of risk factor awareness included older age, insurance status, family income above the poverty line, U.S. origin, having a usual source of health care, and the presence of comorbid conditions. Conclusions Despite the high prevalence of cardiovascular risk factors in U.S. young adults, awareness remains less than ideal. Interventions that target access may increase awareness and facilitate achieving treatment goals in young adults. PMID:29433955

    An examination of cancer incidence patterns in American Indians and Alaska Native (AI/AN) young adults may provide insight into their present and future cancer burden. To reduce racial misclassification, incidence data were linked with the Indian Health Service (IHS) patient services database. Age-adjusted cancer incidence rates per 100,000 (AAR) and corresponding rate ratios (RR) for young adults (ages 20-44 years) were compared across IHS regions and for selected cancers within Contract Health Service Delivery Area counties by race (AI/AN vs non-Hispanic whites [NHW]) and sex. The all-sites cancer incidence rate was lower for AI/ANs (AAR of 83.8) than for NHWs (AAR of 111.2) (RR of 0.75) but varied by IHS regions. Among the leading cancers in AI/AN females the risk was elevated for stomach (RR of 3.22), colorectal (RR of 1.30), uterine (RR of 1.61), and kidney (RR of 1.39) cancers and was lower for breast (RR of 0.70) and thyroid (RR of 0.71) cancers. Among AI/AN young adult males the risk was elevated for stomach (RR of 2.62), liver (RR of 1.89), and kidney (RR of 1.59) cancers and lower for testicular germ cell cancer (RR of 0.64) and lymphoma (RR of 0.60). The risk for these and other cancers varied across IHS regions. Many of the cancer patterns that characterize the AI/AN population overall are apparent among young adults. Compared with NHW young adults, the overall cancer burden among AI/AN young adults was lower but varied for selected cancers and across IHS regions. Cancer control and research strategies are needed to address the unique genetic, social, cultural, and lifestyle aspects of AI/AN young adults.

    2017-07-01

    The Sarnu-Dandali alkaline complex in Rajasthan, northwestern India, is considered to represent early, pre-flood basalt magmatism in the Deccan Traps province, based on a single 40Ar/39Ar age of 68.57 Ma. Rhyolites found in the complex are considered to be 750 Ma Malani basement. Our new 40Ar/39Ar ages of 88.9-86.8 Ma (for syenites, nephelinite, phonolite and rhyolite) and 66.3 ± 0.4 Ma (2σ, melanephelinite) provide clear evidence that whereas the complex has Deccan-age (66 Ma) components, it is dominantly an older (by 20 million years) alkaline complex, with rhyolites included. Basalt is also known to underlie the Early Cretaceous Sarnu Sandstone. Sarnu-Dandali is thus a periodically rejuvenated alkaline igneous centre, active twice in the Late Cretaceous and also earlier. Many such centres with recurrent continental alkaline magmatism (sometimes over hundreds of millions of years) are known worldwide. The 88.9-86.8 Ma 40Ar/39Ar ages for Sarnu-Dandali rocks fully overlap with those for the Indo-Madagascar flood basalt province formed during continental breakup between India (plus Seychelles) and Madagascar. Recent 40Ar/39Ar work on the Mundwara alkaline complex in Rajasthan, 120 km southeast of Sarnu-Dandali, has also shown polychronous emplacement (over ≥ 45 million years), and 84-80 Ma ages obtained from Mundwara also arguably represent post-breakup stages of the Indo-Madagascar flood basalt volcanism. Remnants of the Indo-Madagascar province are known from several localities in southern India but hitherto unknown from northwestern India 2000 km away. Additional equivalents buried under the vast Deccan Traps are highly likely.

    The aim of the present study was to investigate the change in overall life satisfaction for different age groups and between genders over a 20-year period. Data from 1984 to 2008 were extracted from a large prospective longitudinal health study of Nord-Trøndelag (HUNT), Norway. The study included more than 176,000 participants ranging from 20 to 70+ years of age. Data were analysed using logistic regression and adjusted for gender. The analyses revealed an increase in life satisfaction for all age groups from 1984-1986 (HUNT 1) to 1995-1997 (HUNT 2), with the highest levels being reached at 2006-2008 (HUNT 3). For all age groups, the data showed an increase of about 20% for the period from 1984-1986 (HUNT 1) to 1995-1997 (HUNT 2). From 1995-1997 (HUNT 2) to 2006-2008 (HUNT 3), the increase in overall life satisfaction was 16% for the younger age groups, and about 32% for the older age groups (40-69 and 70+ years). Women's scores for overall life satisfaction were higher for nearly all age groups when compared to men using HUNT 3 as a reference. These findings suggest an increase in life satisfaction for all age groups from 1984 to 2008, especially for the older age group (40-69 and 70+ years). The data indicate that women score higher on life satisfaction for most age groups as compared to men.

    To determine reference values for the HMC anomaloscope (Heidelberg multi-color anomaloscope) of healthy subjects. One hundred and thirteen healthy subjects were divided into four age groups: <20 years of age (ten female, five male), 20-39 years of age (23 female, 15 male), 40-59 years of age (23 female, ten male) and >60 years of age (nine female, 18 male). Match midpoint, matching range (MR) and anomaly quotient (AQ), according to the Moreland equation [blue (436 nm) + blue-green (490 nm) = cyan (480 nm) + yellow (589 nm)] and according to the Rayleigh equation [green (546 nm) + red (671 nm) = yellow (589 nm)] were determined. The neutral adaptation was done showing white light every 5 seconds in absolute mode and every 15 seconds in relative mode. The mean match midpoint according to the Rayleigh equation was 43.9 ± 2.6 scale units in absolute mode. It was highest between 20-39 years (45.2 ± 2.2) and lowest in subjects >60 years of age (42.2 ± 2.2). The mean MR in absolute mode was 3.1 ± 3.5 scale units with a maximum >60 years (4.4 ± 4.4). The MR in relative mode was between 1.6 ± 1.9 (20-39 years) and 4.4 ± 3.8 (>60 years). The resulting mean AQ was 1.01 ± 0.15 in both modes. The mean match midpoint of the Moreland equation was 51.0 ± 5.2 scale units in absolute mode. It was highest between 20-39 years (52.5 ± 5.7), and lowest in subjects >60 years of age (48.7 ± 3.6). The mean MR according to the Moreland equation was lower in absolute mode (13.4 ± 15.6) than in relative mode (16.2 ± 15.2). The mean resulting AQ was 1.02 ± 0.21 in both modes. The values of this study can be used as references for the diagnosis of red-green and blue perception impairment with the HMC anomaloscope.

    South Asians are prone to cardiometabolic disease at lower BMI levels than most other ethnic groups, starting in childhood. The magnitude of BMI misclassifications is unknown. To compare the BMI distribution of contemporary South Asian 0-20year olds in the Netherlands with: (1) The South Asian norm reference (secular trends); and (2) The WHO child growth standard and reference. The BMI-for-age distribution of 6677 routine measurements of 3322 South Asian children, aged 0-20 years, was described with the LMS method and BMI z-scores. The BMI distribution in South Asian 0-4 year olds was almost similar to the norm reference (mean BMI z-score = 0.11, skewness = 0.31, SD = 1.0), whereas in 5-19 year olds the distribution had shifted upwards (mean = 0.53) and widened (skewness = -0.12, SD = 1.08). Overweight (incl. obesity) and obesity peaked at 8-10 years, at 45-48% and 35-37%, respectively. Relative to the WHO references, the BMI distribution was left-shifted at ages 0-4 years (mean BMI z-score = -0.46, skewness = 0.23, SD = 0.98) and widened at ages 5-20 years (mean = 0.05; skewness = -0.02, SD = 1.40). At most ages, thinness rates were significantly higher and obesity rates lower than based on South Asian norms. A secular change of BMI-for-age in South Asian children mostly affected children >4 years. WHO references likely under-estimate overweight and obesity rates in South Asian children.

  13. Relationship between age and elite marathon race time in world single age records from 5 to 93 years

    2014-01-01

    Background The aims of the study were (i) to investigate the relationship between elite marathon race times and age in 1-year intervals by using the world single age records in marathon running from 5 to 93 years and (ii) to evaluate the sex difference in elite marathon running performance with advancing age. Methods World single age records in marathon running in 1-year intervals for women and men were analysed regarding changes across age for both men and women using linear and non-linear regression analyses for each age for women and men. Results The relationship between elite marathon race time and age was non-linear (i.e. polynomial regression 4th degree) for women and men. The curve was U-shaped where performance improved from 5 to ~20 years. From 5 years to ~15 years, boys and girls performed very similar. Between ~20 and ~35 years, performance was quite linear, but started to decrease at the age of ~35 years in a curvilinear manner with increasing age in both women and men. The sex difference increased non-linearly (i.e. polynomial regression 7th degree) from 5 to ~20 years, remained unchanged at ~20 min from ~20 to ~50 years and increased thereafter. The sex difference was lowest (7.5%, 10.5 min) at the age of 49 years. Conclusion Elite marathon race times improved from 5 to ~20 years, remained linear between ~20 and ~35 years, and started to increase at the age of ~35 years in a curvilinear manner with increasing age in both women and men. The sex difference in elite marathon race time increased non-linearly and was lowest at the age of ~49 years. PMID:25120915

  14. Aging and shiftwork: the effects of 20 years of rotating 12-hour shifts among petroleum refinery operators.

    The survey was conducted in a Canadian refinery where operators have been working rotating 12-hour shifts for 20 years. A multidisciplinary approach was adopted, based on 12 sources of data. Descriptive statistics and chronoergonomic observations were used. The most marked consequences of the schedule were observed among former shiftworkers. Among current shift workers, sleep deficit, chronic fatigue, health problems, and disruption of social and family life were the most serious effects observed. Aging and under-staffing, however, interact with schedule by necessitating overtime and reducing the actual number of rest days, which in turn affects fatigue and reliability. In the near future, the low replacement rate of the workforce and the limitations on reassignment of aging workers to day shifts will probably prevent the selection process from playing its "protective" role. Besides, with the 5-year delay of the retirement age, the harmful effects in older operators active over the next 5-10 years may prove greater than those observed in this study.

    Evaluation of left ventricular (LV) myocardial deformation by speckle tracking echocardiography (STE) is useful for clinical and research purposes. However, strain measurements depend on the used software. Normative data for QLAB 10 (Philips) are scarce. Additionally, little is known about the influence of anthropometric factors. We aimed to establish normal adult STE-derived strain and strain rate values and to evaluate associations with anthropometrics. One hundred fifty-five healthy subjects aged 20 to 72 years (≥28 subjects per decile) were prospectively gathered and examined with electrocardiography and two-dimensional echocardiography. With STE, we assessed peak systolic LV global longitudinal strain (GLS), segmental longitudinal strain, and strain rate from the three standard apical views. We included 147 healthy subjects (age 44.6±13.7 years, 50% female, GLS -20.8±2.0%). Men had significantly lower GLS than women (-20.1±1.8% vs -21.5±2.0%, P<.001). GLS was significantly lower in subjects with age above 55 years (P=.029), higher blood pressure (P<.001), higher body surface area (BSA, P<.001), larger LV end-systolic and end-diastolic volumes (both P<.001), lower LV ejection fraction (P<.001), and some indices of diastolic function. After multivariable regression analysis, the correlation with systolic blood pressure, E-wave, and LV end-systolic volume remained significant. The systolic strain rates of most segments correlated with BSA. Our study resulted in normative LV GLS values assessed with QLAB 10. Male sex, higher BSA, and higher blood pressure negatively influence GLS. Therefore, these factors should be taken into account for strain interpretation in clinical practice. © 2016, Wiley Periodicals, Inc.

    The purpose of this study was to establish normative reference values for spatiotemporal and plantar pressure parameters, and to investigate the influence of demographic, anthropometric and physical characteristics. In 1000 healthy males and females aged 3-101 years, spatiotemporal and plantar pressure data were collected barefoot with the Zeno™ walkway and Emed ® platform. Correlograms were developed to visualise the relationships between widely reported spatiotemporal and pressure variables with demographic (age, gender), anthropometric (height, mass, waist circumference) and physical characteristics (ankle strength, ankle range of motion, vibration perception) in children aged 3-9 years, adolescents aged 10-19 years, adults aged 20-59 years and older adults aged over 60 years. A comprehensive catalogue of 31 spatiotemporal and pressure variables were generated from 1000 healthy individuals. The key findings were that gait velocity was stable during adolescence and adulthood, while children and older adults walked at a comparable slower speed. Peak pressures increased during childhood to older adulthood. Children demonstrated highest peak pressures beneath the rearfoot whilst adolescents, adults and older adults demonstrated highest pressures at the forefoot. Main factors influencing spatiotemporal and pressure parameters were: increased age, height, body mass and waist circumference, as well as ankle dorsiflexion and plantarflexion strength. This study has established whole of life normative reference values of widely used spatiotemporal and plantar pressure parameters, and revealed changes to be expected across the lifespan.

  17. The 40Ar/39Ar age record and geodynamic significance of Indo-Madagascar and Deccan flood basalt volcanism in the Sarnu-Dandali alkaline complex, Rajasthan, northwestern India

    The Sarnu-Dandali alkaline complex in Rajasthan, northwestern India, is considered to represent early, pre-tholeiite magmatism in the Deccan Traps continental flood basalt (CFB) province, based on a single 40Ar/39Ar age of 68.57 Ma. Rhyolites found in the complex are considered to be 750 Ma Malani basement. Our new 40Ar/39Ar ages of 88.9-86.8 Ma (for syenites, nephelinite, phonolite and rhyolite) and 66.3 ± 0.4 Ma (2σ, melanephelinite) provide clear evidence that whereas the Sarnu-Dandali complex has Deccan-age components, it is dominantly an older (by ˜20 million years) alkaline complex, with rhyolites included. Sarnu-Dandali is thus an alkaline igneous center active at least twice in the Late Cretaceous, and also much before as suggested by a basalt flow underlying the Early Cretaceous Sarnu Sandstone. The 89-86 Ma 40Ar/39Ar ages fully overlap with those for the Indo-Madagascar CFB province formed during continental break-up between India (plus Seychelles) and Madagascar. Recent 40Ar/39Ar work has shown polychronous emplacement (over ≥ 45 million years) of the Mundwara alkaline complex in Rajasthan, 100 km from Sarnu-Dandali, and 84-80 Ma ages obtained from Mundwara also arguably represent late stages of the Indo-Madagascar CFB volcanism. Remnants of the Indo-Madagascar CFB province are known from several localities in southern India but hitherto unknown from northwestern India 2000 km away. Additional equivalents buried under the vast Deccan Traps are highly likely. We relate the Sarnu-Dandali and Mundwara complexes to decompression melting of ancient, subduction-fluxed, enriched mantle lithosphere due to periodic lithospheric extension during much of the Cretaceous, and hundreds of kilometers inland from the India-Madagascar and India-Seychelles rifted margins.

    While heavier weight is known to increase the incidence of dyslipidemia, limited data are available on the relationship between weight gain and its development. A total of 2647 males were categorized into the following four groups according to the difference between their self-reported weight at 20 years of age and their measured weight in 1994-95: a loss of ≥5% (decrease), loss of <5% or gain of <5% (no change), gain of ≥5 to <15% (increase) and gain of ≥15% (sizable increase). They were followed up until their 2002-03 health examination. Using the 'no change' group as reference, the multivariable-adjusted odds ratio (adjusted for age, body mass index at 20 years of age, physical activity, smoking and alcohol intake) and 95% confidence interval (95% CI) for the incidence of dyslipidemia were determined using logistic regression models. A total of 1342 participants developed dyslipidemia during the follow-up period. The 'increase' and 'sizable increase' groups had odds ratios for the incidence of dyslipidemia of 1.97 (95% CI, 1.59-2.45) and 2.68 (2.15-3.34), respectively, demonstrating that there was a significant dose-response association between weight gain since 20 years of age and the incidence of dyslipidemia (P < 0.001 for trend). These results suggest that dyslipidemia could be prevented by avoiding weight gain in adulthood. © The Author 2015. Published by Oxford University Press on behalf of Faculty of Public Health.

    The National Health and Nutrition Examination Survey (NHANES) is a nationally representative, population-based survey designed to assess the health and nutritional status of the civilian, non-institutionalized US population. Data were collected through a personal interview regarding health history and through physical examination. Earlier NHANES surveys were conducted on a periodic basis; however, in 1999, NHANES began collecting data on a continuing, annual basis. During NHANES I, which ran from 1971-1975, audiometric testing was conducted on adults aged 25-74 years. No subsequent testing of adults was conducted in the NHANES program until 1999, when NHANES began audiometric testing of adults aged 20-69 years. This report examines the hearing levels for adults in the United States and compares them with the hearing data from NHANES I. Hearing levels are grouped by age and are grouped by ethnicity and gender.

    Objective To obtain normative longitudinal vestibulo-ocular and balance test data in children from ages 3 to 9 with normal middle-ear status. Study Design Prospective, longitudinal cohort Setting Tertiary care pediatric hospital Subjects and Methods Three-year-old children were entered and tested yearly. Subjects underwent earth vertical axis rotation testing using sinusoidal and constant velocity stimuli and performed the Sensory Organization Test. Results One hundred forty-eight children were entered and usable data were collected on 127 children. A linear increase in the vestibulo-ocular reflex gain as children aged was found, without a change in the phase of the response. An age-related linear increase in Equilibrium Scores, indicating reduced postural sway, was also observed. Conclusion These normative data can be used in the evaluation of dizziness and balance disorders in children. PMID:20416461

    To assess the cumulative costs and consequences of double embryo transfer (DET) or elective single embryo transfer (eSET) in women commencing in vitro fertilisation (IVF) treatment aged 32, 36 and 39 years. Microsimulation model. Three assisted reproduction centres in Scotland. A total of 6153 women undergoing treatment at one of three Scottish IVF clinics, between January 1997 and June 2007. A microsimulation model, populated using data inputs derived from a large clinical data set and published literature, was developed to compare the costs and consequences of using eSET or DET over multiple treatment cycles. Disability-free live births; twin pregnancy rate; women's quality-adjusted life-years (QALYs); health service costs. Not only did DET produce a higher cumulative live birth rate compared with eSET for women of all three ages, but also a higher twin pregnancy rate. Compared with eSET, DET ranged from costing an additional £ 27,356 per extra live birth in women commencing treatment aged 32 years, to costing £ 15,539 per extra live birth in 39-year-old women. DET cost ∼ £ 28,300 and ∼ £ 20,300 per additional QALY in women commencing treatment aged 32 and 39 years, respectively. Considering the high twin pregnancy rate associated with DET, coupled with uncertainty surrounding QALY gains, eSET is likely to be the preferred option for most women aged ≤ 36 years. The cost-effectiveness of DET improves with age, and may be considered cost-effective in some groups of older women. The decision may best be considered on a case-by-case basis for women aged 37-39 years. © 2011 The Authors BJOG An International Journal of Obstetrics and Gynaecology © 2011 RCOG.

    Survivors of teenage and young adult cancer are at risk of cerebrovascular events, but the magnitude of and extent to which this risk varies by cancer type, decade of diagnosis, age at diagnosis, and attained age remains uncertain. This is the largest-ever cohort study to evaluate the risks of hospitalization for a cerebrovascular event among long-term survivors of teenage and young adult cancer. The population-based TYACSS (Teenage and Young Adult Cancer Survivor Study) (N=178,962) was linked to Hospital Episode Statistics data for England to investigate the risks of hospitalization for a cerebrovascular event among 5-year survivors of cancer diagnosed when 15 to 39 years of age. Observed numbers of first hospitalizations for cerebrovascular events were compared with that expected from the general population using standardized hospitalization ratios (SHRs) and absolute excess risks per 10 000 person-years. Cumulative incidence was calculated with death considered a competing risk. Overall, 2782 cancer survivors were hospitalized for a cerebrovascular event-40% higher than expected (SHR=1.4, 95% confidence interval, 1.3-1.4). Survivors of central nervous system (CNS) tumors (SHR=4.6, 95% confidence interval, 4.3-5.0), head and neck tumors (SHR=2.6, 95% confidence interval, 2.2-3.1), and leukemia (SHR=2.5, 95% confidence interval, 1.9-3.1) were at greatest risk. Males had significantly higher absolute excess risks than females (absolute excess risks =7 versus 3), especially among head and neck tumor survivors (absolute excess risks =30 versus 11). By 60 years of age, 9%, 6%, and 5% of CNS tumor, head and neck tumor, and leukemia survivors, respectively, had been hospitalized for a cerebrovascular event. Beyond 60 years of age, every year, 0.4% of CNS tumor survivors were hospitalized for a cerebral infarction (versus 0.1% expected), whereas at any age, every year, 0.2% of head and neck tumor survivors were hospitalized for a cerebral infarction (versus 0

    Slum-resettlement communities are increasingly adopting urban lifestyles. The aim of this study was to assess the prevalence and identify correlates of hypertension among residents aged 20-59 years of a slum-resettlement colony. A community-based cross-sectional study was done from 2010 to 2012 in NandNagri, a slum-resettlement area in east Delhi. 310 participants aged 20-59 years were enrolled through multistage systematic random sampling. Each study subject was interviewed and examined for raised blood pressure; data on risk factors including smoking, alcohol intake, physical activity and salt consumption were also collected. Data were analysed by use of univariate and multivariate regression. The overall prevalence of hypertension was 17.4% and 35% participants were prehypertensive. On multiple logistic regression, age 40-49 years (P = 0.020) and 50-59 years (P = 0.012), clerical/professional occupation (P = 0.004), abnormal waist circumference (≥90 cm in males and ≥ 80 cm in females; P = 0.001), positive family history of hypertension in both parents (P = 0.013) and above-average daily salt intake (P = 0.000) were significantly associated with hypertension. These findings indicate that hypertension is a significant health problem in the study population. Many study participants diagnosed with prehypertension are at risk of developing hypertension, thus immediate public-health interventions are indicated.

    Initial treatment for amblyopia of the fellow eye with patching and atropine sulfate eyedrops improves visual acuity. Long-term data on the durability of treatment benefit are needed. To report visual acuity at 15 years of age among patients who were younger than 7 years when enrolled in a treatment trial for moderate amblyopia. In a multicenter clinical trial, 419 children with amblyopia (visual acuity, 20/40 to 20/100) were randomly assigned to patching (minimum of 6 h/d) or atropine sulfate eyedrops, 1% (1 drop daily), for 6 months. Treatment after 6 months was at the discretion of the investigator. Two years after enrollment, an unselected subgroup of 188 children were enrolled into long-term follow-up. Initial treatment with patching or atropine with subsequent treatment at investigator discretion. Visual acuity at 15 years of age with the electronic Early Treatment Diabetic Retinopathy Study test in amblyopic and fellow eyes. Mean visual acuity in the amblyopic eye measured in 147 participants at 15 years of age was 0.14 logMAR (approximately 20/25); 59.9% of amblyopic eyes had visual acuity of 20/25 or better and 33.3%, 20/20 or better. Mean interocular acuity difference (IOD) at 15 years of age was 0.21 logMAR (2.1 lines); 48.3% had an IOD of 2 or more lines and 71.4%, 1 or more lines. Treatment (other than spectacles) was prescribed for 9 participants (6.1%) aged 10 to 15 years. Mean IOD was similar at examinations at 10 and 15 years of age (2.0 and 2.1 logMAR lines, respectively; P = .39). Better visual acuity at the 15-year examination was achieved in those who were younger than 5 years at the time of entry into the randomized clinical trial (mean logMAR, 0.09) compared with those aged 5 to 6 years (mean logMAR, 0.18; P < .001). When we compared subgroups based on original treatment with atropine or patching, no significant differences were observed in visual acuity of amblyopic and fellow eyes at 15 years of age (P = .44 and P = .43

  11. Ar-40/Ar-39 age of the Shergotty achondrite and implications for its post-shock thermal history

    Ar-40/Ar-39 measurements are used to determine the age of the Shergotty achondrite and the chronology of the shock event responsible for the complete conversion of its plagioclase to maskelynite is discussed. Apparent ages are found to vary between 240 and 640 million years for the whole rock sample, with a plateau age of 254 million years for a maskelynite separate. The Rb-Sr age of 165 million years determined by Nyquist at al (1978) suggests that the maskelynite as well as the whole rock was incompletely degassed. Argon diffusion characteristics indicate a post-shock cooling time greater than 1000 years and a burial depth greater than 300 m for a thermal model of a cooling ejecta blanket of variable thickness. It is concluded that the shock event which degassed the argon and reset the Rb-Sr systematics occurred between 165 and 250 million years ago when the parent body experienced a collision in the asteroid belt.

    The aims of the present study are to analyse the association between marital status at age 24, 29, 34, and 39 years and subsequent mortality in a cohort of men born in 1953 (sensitive period); to study the impact of number of years married, number of years divorced/widowed, and number of marital break-ups on mortality (cumulative effect), and to examine whether these effects were independent of marital status at age 39 (proximity effect). Prospective birth cohort study with follow-up of mortality from 1992 to 2002. Participants were 10891 men born within the metropolitan area of Copenhagen, Denmark. Marital status in 1992 as well as start and termination of all previous marital status events from 1968 to 1992 were retrieved from the Danish Civil Registration System. Were hazard ratios (HR) for all-cause mortality from age 40 to 49 years. We found a strong protective effect of being married compared with never being married or divorced/widowed at every age. The association increased in strength with increasing age. Number of years divorced was associated with increased mortality risk in a dose-dependent manner at age 34 and 39 years. One or more marital break-ups was associated with higher mortality, whereas increasing number of years married was associated with lower mortality. Inclusion of current marital status attenuated the strength of the associations but most of them remained statistically significant. Marital status and cumulated marital periods, especially cumulated periods divorced/widowed are strong independent predictors of mortality among younger males.

    We studied relationships between age and aerobic capacity in three groups of subjects adhering to different exercise modalities. A total of 203 men aged 20-90 years were examined: 52 speed-power track and field athletes (SP), 89 endurance runners (ER) and 62 untrained individuals (UT). Maximal exercise characteristics were obtained during a graded treadmill test until exhaustion: oxygen uptake (VO2max), heart rate (HRmax), oxygen pulse (O2 Pulsemax) and maximal distance (Distmax). Information about training history and weekly training amount was collected. A linear model of regression was adopted. VO2max in SP was lower than in ER, but significantly higher than in UT. The cross-sectional rates of decline in body mass-adjusted VO2max and Distmax were significantly smaller in SP than in ER and UT. About 80 years of age, the levels of VO2max and Distmax reached similar values in SP and ER. The decline in HRmax, but not in O2 Pulsemax was suggested as a cardiac adaptation accounting for between-group differences in VO2max loss. Weekly training volume was a significant positive predictor of age-related changes in aerobic capacity. In conclusion, not only endurance, but also speed-power exercise appears adequate to ensure an elevated aerobic capacity at old age. © 2012 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    Anthrax vaccine adsorbed (AVA, BioThrax(®)) is recommended for post-exposure prophylaxis administration for the US population in response to large-scale Bacillus anthracis spore exposure. However, no information exists on AVA use in children and ethical barriers exist to performing pre-event pediatric AVA studies. A Presidential Ethics Commission proposed a potential pathway for such studies utilizing an age de-escalation process comparing safety and immunogenicity data from 18 to 20 year-olds to older adults and if acceptable proceeding to evaluations in younger adolescents. We conducted exploratory summary re-analyses of existing databases from 18 to 20 year-olds (n=74) compared to adults aged 21 to 29 years (n=243) who participated in four previous US government funded AVA studies. Data extracted from studies included elicited local injection-site and systemic adverse events (AEs) following AVA doses given subcutaneously at 0, 2, and 4 weeks. Additionally, proportions of subjects with ≥4-fold antibody rises from baseline to post-second and post-third AVA doses (seroresponse) were obtained. Rates of any elicited local AEs were not significantly different between younger and older age groups for local events (79.2% vs. 83.8%, P=0.120) or systemic events (45.4% vs. 50.5%, P=0.188). Robust and similar proportions of seroresponses to vaccination were observed in both age groups. AVA was safe and immunogenic in 18 to 20 year-olds compared to 21 to 29 year-olds. These results provide initial information to anthrax and pediatric specialists if AVA studies in adolescents are required. Copyright © 2015 Elsevier Ltd. All rights reserved.

    The prevalence of disability at the age of 75+ measured by the Katz Index of Activities of Daily Living (ADL) was compared among three birth cohorts: those born < or = 1903 (n = 348), those born < or = 1913 (n = 586), and those born < or = 1923 (n = 758). Significant risk factors for disability were female sex and age; the cohort effect was not significant. The prevalence rates of disability were 29.0% (95% CI 24.2-33.8), 34.8% (30.9-38.7), and 28.8% (25.5-32.0) for the first, second, and third cohorts. In the age group 75-79 years the rates were 20.1% (95% CI 13.8-26.4), 25.5% (20.2-30.7), and 14.4% (10.6-18.1). The change was due to the declining disability of women. The distributions in the three cohorts based on the numbers of ADL limitations did not differ. As far as the whole aged populations were concerned, longer life was not accompanied by improving health.

  17. Demonstration of a Groundwater Age Determination Using 39Ar in Support of a Multi-Tracer Groundwater Analysis of Wells in Fresno, CA

    Argon-39 has a half-life of 269 years, making it an ideal tracer for groundwater dating in the age range of 50-1000 years. In September 2014, two production wells within the San Joaquin Valley Aquifer System, located in Fresno, CA were sampled and analyzed for a suite of inorganic and organic contaminants and isotopic constituents. The radiotracers 3H (< 50 years) and 14C (> 1000 years) are routinely measured as part of the U. S. Geological Survey (USGS) National Water Quality Assessment (NAWQA) Enhanced Trends Network project. Adding 39Ar to the suite of tracers provides age data in the intermediate range to refine the groundwater age distribution of mixed waters and establishes groundwater residence times and flow rates. Characterizing the groundwater recharge and flow rate is of particular interest at these wells for determining the sources and movement of contaminants in groundwater, particularly nitrate, DBCP, and perchlorate. The sampled wells were pumped and purged. The sample collection for the 39Ar measurements required extracting the dissolved gases from 3000-5000 L of groundwater using a membrane degasification system with a maximum flow rate of 50 gpm (11.4 m^3/hr). The membranes are plastic hollow fibers that are hydrophobic. The gas was collected in duplicate large aluminum coated plastic sample bags. The gas was purified and then counted via direct beta counting using ultra-low background proportional counters loaded with a mixture of geologic Ar and methane to enhance the sensitivity for Ar measurements. The activity of 39Ar is 1.01 Bq/kg Ar, corresponding to an abundance of 0.808 ppq. The estimated absolute ages of the samples from the two groundwater wells were 23.3 and 27.0 percent of modern Ar. The comparison of the groundwater residence times determined using the suite of radiotracers (3H, 39Ar, and 14C) highlighted the value of knowing the intermediate age of groundwater when determining contaminant fate and transport pathways.

    Early childhood (under five years of age) is a critical developmental period when children's physical activity behaviours are shaped and when physical activity patterns begin to emerge. Physical activity levels track from early childhood through to adolescence with low levels of physical activity associated with poorer health. The aims of this study were to examine cross-sectional and longitudinal associations between the physical activity levels of fathers and their children at the ages of 20 months, 3.5 and 5 years, and to investigate whether these associations differed based on paternal body mass index (BMI) and education. The Melbourne Infant Feeding Activity and Nutrition Trial (InFANT) Program was a cluster randomized-controlled trial delivered to pre-existing first-time parent groups. Physical activity levels of fathers and their first-born children were assessed using the Active Australia Survey and ActiGraph accelerometers respectively. Cross-sectional associations between father and child physical activity behaviours were assessed at each time point. Longitudinal associations between father and child physical activity were also investigated from child age 20 months to both 3.5 and 5 years. Additional stratified analyses were conducted based on paternal BMI and paternal education as a proxy for socioeconomic position (SEP). Data from the control and interventions groups were pooled and all analyses adjusted for intervention status, clustering by first-time parent group and accelerometer wear time. Physical activity levels of fathers and their children at child age 20 months were not associated cross-sectionally or longitudinally at child age 3.5 and 5 years. Positive associations were observed between light physical activity of healthy weight fathers and children at age 3.5 years. Inverse associations were observed for moderate/vigorous physical activity between fathers and children at age 5 years, including between overweight/obese fathers and their

    Geochronologic studies of high-pressure/low-temperature rocks can be used to determine the timing and rates of burial and exhumation in subduction zones by dating different stages of the pressure-temperature history. In this study, we present new in situ UV laser ablation 40Ar/39Ar phengite ages from a suite of lawsonite blueschist- and eclogite-facies rocks representing different protoliths (metabasalt, metasediment), different structural levels (within and outside of a high-strain zone), and different textural positions (eclogite pod core vs. margin) to understand the timing of these events in an exhumed Neo-Tethyan subduction zone (Sivrihisar Massif, Tavşanlı Zone, Turkey). Weighted mean in situ 40Ar/39Ar ages of phengite from the cores of lawsonite eclogite pods (90-93 Ma) are distinctly older than phengite from retrogressed, epidote eclogite (82 ± 2 Ma). These ages are interpreted as the age of peak and retrograde metamorphism, respectively. Eclogite records the narrowest range of ages (10-14 m.y.) of any rock type analyzed. Transitional eclogite- and blueschist-facies assemblages and glaucophane-rimmed lawsonite + garnet + phengite veins from eclogite pod margins record a much wider age range of 40Ar/39Ar ages (~20 m.y.) with weighted mean ages of ~91 Ma. Blueschists and quartzites record more variable 40Ar/39Ar ages that may in part be related to structural position: samples within a high-strain zone at the tectonic contact of the HP rocks with a meta-ultramafic unit have in situ UV laser ablation 40Ar/39Ar ages of 84.0 ± 1.3-103.7 ± 3.1 Ma, whereas samples outside this zone range to older ages (84.6 ± 2.4-116.7 ± 2.7 Ma) and record a greater age range (22-38 m.y.). The phengite ages can be correlated with the preservation of HP mineral assemblages and fabrics as well as the effects of deformation. Collectively, these results show that high-spatial resolution UV laser ablation 40Ar/39Ar phengite data, when considered in a petrologic and structural

    To investigate the prevalence of obstructive sleep apnea-hypopnea syndrome (OSAHS) in adults aged over 20 years in Changchun city, providing epidemiological data for treatment and prevention of the disease. 3,960 subjects were derived from a stratified cluster and random sampling of the population in two districts of Changchun city. They were asked to answer the questions from a questionnaire in their houses. According to the degree of snoring, 200 subjects with a snoring score >or= 2 degree were selected to undergo polysomnography for a whole night and the prevalence of the disease was estimated. A total of 3,648 (97.64%) validated questionnaires was collected. Of them 31.00% had a snoring score >or= 2 degree, the prevalence was higher in males (40.07%) than in females (21.76%). The prevalence of snoring was higher in drivers (42.47%) than in other occupations. The estimated prevalence of OSAHS defined by apnea-hypopnea index (AHI) >or= 5, Epworth sleepiness scale (ESS) >or= 9 and arterial oxygen saturation (SaO(2)) < 90% was 4.81%. The estimated prevalence of OSAHS in adults aged over 20 years in Changchun city was 4.81%. Doctors should pay more attention to the disease and the ordinary people should be informed of the health impact of snoring and OSAHS.

    To examine differences in life expectancy with cognitive impairment among older Mexican adults according to nativity (U.S.-born/foreign-born) and among immigrants, age of migration to the United States. This study employs 20 years of data from the Hispanic Established Populations for the Epidemiologic Study of the Elderly to estimate the proportion of life spent cognitively healthy and cognitively impaired prior to death among older Mexican adults residing in the southwestern United States. We combine age-specific mortality rates with age-specific prevalence of cognitive impairment, defined as a Mini-Mental Status Exam score of less than 21 points to calculate Sullivan-based life table models with and without cognitive impairment in later life. Foreign-born Mexican immigrants have longer total life expectancy and comparable cognitive healthy life expectancy regardless of gender compared to U.S.-born Mexican-Americans. However, the foreign-born spend a greater number of years after age 65 with cognitive impairment relative to their U.S.-born counterparts. Furthermore, we document an advantage in life expectancy with cognitive impairment and proportion of years after age 65 cognitively healthy among mid-life immigrant men and women relative to early- and late-life migrants. The relationship between nativity, age of migration, and life expectancy with cognitive impairment means that the foreign-born are in more need of support and time-intensive care in late life.

    Objective. The aim of this study was to evaluate the effect of maternal age on prenatal and obstetric outcome in multiparaous women. Materials and Methods. A retrospective case control study was conducted, including women aged 40 years and over (study group, n = 97) who delivered at 20 week's gestation or beyond and women aged 20–29 years (control group, n = 97). Results. The mean age of women in the study group was 41.2 ± 1.7 years versus 25.4 ± 2.3 years in the control group. Advanced maternal age was associated with a significantly higher rate of hypertension, diabetes mellitus, fetal complication, and 5-minute Apgar scores <7 (P < 0.05). Caeserean section rate, incidence of placental abruption, preterm delivery, and neonatal intensive care unit admission were more common in the older group, but the differences were not statistically significant. Conclusions. Advanced maternal age is related to maternal and neonatal complications. PMID:25954770

    A common feature observed in 40Ar/39Ar age spectra of extraterrestrial (ET) rocks is a conspicuous decrease in the ages of high temperature extractions relative to lower temperature steps and a correlated increase in Ca/K, often succeeded by a monotonic increase in ages. This feature is routinely attributed to recoil-implanted 39Ar from a potassium (K)-rich donor phase into a K-poor receptor phase (e.g., 1,2). While 39Ar recoil redistribution is undoubtedly manifested in many terrestrial and ET 40Ar/39Ar whole-rock age spectra, it cannot easily explain the magnitude of high release temperature 40Ar*/39ArK anomalies observed in Martian meteorites ALH 84001 and Nakhla, as well as other course-grained meteorites and lunar rocks. Depending on the aliquot and sample, 50 - 100% of the pyroxene release spectra in ALH 84001 and Nakhla appear strongly perturbed to lower ages. As the mean recoil distance of 39Ar ~0.1 µm, the recoil hypothesis demands that a high-K phase be ubiquitously distributed amongst sub-micron to micron sized pyroxene crystals to account for the observed pyroxene age spectra. However, in both Nakhla and ALH 84001, pyroxene is often completely isolated from high-K phases and individual grains commonly exceed 100 µm in diameter. 40Ar/39Ar analyses of pyroxene-bearing terrestrial basalts, wherein fine-grained pyroxene and plagioclase are intimately adjoined, show that recoil-implanted 39Ar into pyroxene produces much less precipitous anomalies in 40Ar*/39ArK, as predicted by the recoil lengthscale. An alternative hypothesis is that whole-rock age spectra of ET samples with anomalously low ages at high temperatures may reflect diffusive 40Ar distributions within considerably degassed pyroxene grains. Owing to apparent differences in activation energies between glass and/or plagioclase and pyroxene, 40Ar may diffuse more rapidly from pyroxene under certain high-temperature conditions (i.e., above the temperature at which the extrapolated Ar Arrhenius

    To examine the 20-year trends in the combined prevalence of overweight and obesity among children aged 0–6 years between 1995 and 2015 in Harbin, China, we selected altogether 49,553 children aged 0–6 years old by using a multistage stratified cluster sampling methods in Harbin, one provincial capital city in northeast China in 1995, 2005 and 2015. Height and weight information of the children were collected. We used the child growth standards of World Health Organization to calculate the Z-scores for body mass index (BMI). Cut-offs recommended by World Health Organization and International Obesity Task Force were used to define overweight and obesity for each children. We found there is no difference between boys’ BMI and girls’ among newborns in each survey point (p>0.05), but in older age groups, the BMI of boys was higher than that of girls (p<0.05). From 1995 to 2015, the average BMI was increasing continuously among boys older than 42 months and girls older than 48 months (p<0.01 for linear trend across year) in Harbin. The combined prevalence of overweight and obesity increased from 2.6% in 1995 to 7.6% in 2015. For every 10-year the risk of combined overweight and obesity in children aged 0–6 years increased by 167% (95%CI: 146%, 188%, p<0.01). The combined prevalence of overweight and obesity in most age subgroups showed an increasing trend over time (p<0.01 for trend test across survey year). The age when the combined prevalence of overweight and obesity dramatically increased was earlier in 2015 than that in 2005 and 1995. In conclusion, there was an increasing trend of the combined prevalence of overweight and obesity during the past 20 years in Harbin and the age when the prevalence dramatically increased became earlier. Comprehensive intervention should be undertaken among younger children to prevent and control children’s overweight and obesity. PMID:29864123

    To prospectively evaluate the relationship between the presence or persistence of anterior knee pain (AKP) during the first 2-years following anterior cruciate ligament reconstruction (ACLR) and patellofemoral osteoarthritis (PFOA) at 15- and 20-years. This study was ancillary to a long-term prospective cohort study of 221 participants following bone-patellar-tendon-bone ACLR. AKP was assessed at 1- and 2-years post-ACLR using part of the Cincinnati knee score with an additional pain location question (persistence defined as presence at both follow-ups). Radiographic PFOA (definite patellofemoral osteophyte) and symptomatic PFOA (patellofemoral osteophyte, with knee pain during past 4 weeks) was assessed at 15- and 20-years follow-up. We used generalized linear models with Poisson regression to assess the relationship between AKP and PFOA. Of the 181 participants (82%) who were assessed at 15-years post-ACLR (age 39 ± 9 years; 42% female), 36 (24%) and 33 (22%) had AKP at 1- and 2-years, respectively, while 14 (8%) reported persistent AKP. Radiographic and symptomatic PFOA was observed at 15-years in 130 (72%) and 70 (39%) participants, respectively, and at 20-years in 115 (80%) and 60 (42%) participants, respectively. Neither the presence nor persistence of AKP at 1- and/or 2-years post-ACLR was associated with significantly higher risk of radiographic or symptomatic PFOA at 15- or 20-years (risk ratios <2.1). Although AKP and PFOA were prevalent, AKP does not appear to be associated with long-term PFOA following ACLR. Copyright © 2016 Osteoarthritis Research Society International.

    Geochronologic studies of high-pressure/low-temperature rocks can be used to determine the timing and rates of burial and exhumation in subduction zones by dating different stages of the pressure–temperature history. In this study, we present new in situ UV laser ablation 40Ar/39Ar phengite ages from a suite of lawsonite blueschist- and eclogite-facies rocks representing different protoliths (metabasalt, metasediment), different structural levels (within and outside of a high-strain zone), and different textural positions (eclogite pod core vs. margin) to understand the timing of these events in an exhumed Neo-Tethyan subduction zone (Sivrihisar Massif, Tavşanlı Zone, Turkey). Weighted mean in situ 40Ar/39Ar ages of phengite from the cores of lawsonite eclogite pods (90–93 Ma) are distinctly older than phengite from retrogressed, epidote eclogite (82 ± 2 Ma). These ages are interpreted as the age of peak and retrograde metamorphism, respectively. Eclogite records the narrowest range of ages (10–14 m.y.) of any rock type analyzed. Transitional eclogite- and blueschist-facies assemblages and glaucophane-rimmed lawsonite + garnet + phengite veins from eclogite pod margins record a much wider age range of 40Ar/39Ar ages (~20 m.y.) with weighted mean ages of ~91 Ma. Blueschists and quartzites record more variable 40Ar/39Ar ages that may in part be related to structural position: samples within a high-strain zone at the tectonic contact of the HP rocks with a meta-ultramafic unit have in situ UV laser ablation 40Ar/39Ar ages of 84.0 ± 1.3–103.7 ± 3.1 Ma, whereas samples outside this zone range to older ages (84.6 ± 2.4–116.7 ± 2.7 Ma) and record a greater age range (22–38 m.y.). The phengite ages can be correlated with the preservation of HP mineral assemblages and fabrics as well as the effects of deformation. Collectively, these results show that high-spatial resolution UV laser ablation 40Ar/39Ar phengite data, when considered

    Young women (20-39 years-old) with breast cancer are diagnosed with more aggressive tumours and consequently have poorer survival. However, there is an evidence gap as to whether age has an independent effect on survival of pre-menopausal women diagnosed with HR+/Her2- tumours. The aim of this population-based study was to compare characteristics at diagnosis, determinants of treatment and survival in women aged 20-39 and 40-49 years diagnosed with HR+/Her2- tumours. From the National Cancer Registry Ireland, we identified women aged 20-49 diagnosed with a first invasive HR+/Her2- breast cancer during 2002-2008. Women aged 20-39 were compared to those aged 40-49 years. Poisson regression with robust error variance was used to explore the impact of age on treatment receipt. Associations between age and survival from all causes was investigated using Cox models. In multivariate models, women aged 20-39 significantly more often having no cancer-directed surgery (IRR=1.49, 95%CI 1.07, 2.08). In those having surgery, younger age was associated with significantly higher likelihood of receiving chemotherapy; age was not associated with receipt of adjuvant radiotherapy or endocrine therapy. Women aged 20-39 undergoing surgery were significantly more likely to die than women aged 40-49 (HR=1.84, 95%CI: 1.31, 2.59). Age is an independent prognostic factor in younger women diagnosed with HR+/Her2- breast cancer, supporting the hypothesis that breast cancer in women under 40 has more aggressive behaviour, even within HR+/Her2- tumours. Future research should explore the reasons for poorer survival in order to inform strategies to improve outcomes in this age group. Copyright © 2016 Elsevier Ltd. All rights reserved.

  13. 40Ar/39Ar laser fusion and K-Ar ages from Lathrop Wells, Nevada, and Cima, California. The age of the latest volcanic activity in the Yucca Mountain area

    K-Ar and 40Ar/39Ar ages from the Lathrop Wells volcanic center, Nevada, and from the Cima volcanic field, California, indicate that the recently reported 20-ka age estimate for the Lathrop Wells volcanic center is incorrect. Instead an age of 119??11 to 141??10 ka is indicated for the Lathrop Wells volcanic center. This age corrected is concordant with the ages determined by two independent isotopic geochronometric techniques and with the stratigraphy of surficial deposits in the Yucca Mountain region. In addition, paleomagnetic data and radiometric age data indicate only two volcanic events at the Lathrop Wells volcanic center that are probably closely linked in time, not as many as five as recently reported.

    People from Asian populations are generally shorter than other ethnic groups. It is unknown if current universal height references are suitable for affluent South Asian children in the Netherlands. To develop height-for-age charts for contemporary South Asian children aged 0-20 years living in the Netherlands, to evaluate secular trends, and to compare the charts with current Asian Indian, Dutch and WHO references. A population-based study measured 3315 South Asian children aged 0-20 years between 2007-2010. Among this cohort, 6876 measurements were taken. Another 7388 measurements were taken of a historical cohort of 1078 children born between 1974-1976 (aged 0-18 years). An upward trend in height was observed for South Asian children living in the Netherlands between 1992-2010. The height-for-age charts of the South Asian historical cohort were similar to current Asian Indian charts. South Asian children in the Netherlands were shorter than their Dutch contemporaries at every age; and these differences increased further during adolescence. Compared to the WHO height-for-age references, there were considerable discrepancies in height, with curves intersecting twice. The discrepancies between the South Asian and Dutch and WHO height-for-age references indicate differences in growth patterns between the source populations.

    Late adolescence (ie, 16-20 years of age) is a period characterized by escalation of drinking and alcohol use problems for many and by the onset of an alcohol use disorder for some. This heightened period of vulnerability is a joint consequence of the continuity of risk from earlier developmental stages and the unique neurologic, cognitive, and social changes that occur in late adolescence. We review the normative neurologic, cognitive, and social changes that typically occur in late adolescence, and we discuss the evidence for the impact of these transitions on individual drinking trajectories. We also describe evidence linking alcohol abuse in late adolescence with neurologic damage and social impairments, and we discuss whether these are the bases for the association of adolescent drinking with increased risks of mental health, substance abuse, and social problems in adulthood. Finally, we discuss both the challenges and successes in the treatment and prevention of adolescent drinking problems. PMID:18381495

    Cognitive evaluation of young subjects is now widely carried out for non-traumatic diseases such as multiple sclerosis, HIV, or sleep disorders. This evaluation requires normative data based on healthy adult samples. However, most clinicians use a set of tests that were normed in an isolated manner from different samples using different cutoff criteria. Thus, the score of an individual may be considered either normal or impaired according to the norms used. It is well established that healthy adults obtained low-test scores when a battery of tests is administered. Thus, the knowledge of low base rates is required so as to minimize false diagnosis of cognitive impairment. The aim of this study was twofold (1) to provide normative data for RAPID-II battery in healthy adults, and (2) estimate the proportion of healthy adults having low scores across this battery. Norms for the 44 test scores of the RAPID-II test battery were developed using the overall sample of 335 individuals based on three categories of age (20 to 29, 30 to 39, and 40 to 49 years) and two educational levels: Baccalaureate or higher educational degree (high educational level), lower than baccalaureate (low educational level). The 5th, 25th, 50th, and 75th percentiles were calculated from the six age and education subsamples and used to define norms. The frequency of low scores on the RAPID-II battery was calculated by simultaneously examining the performance of 33 primary scores. A low score was defined as less than or equal to the 5th percentile drawn from the six age and education normative subsamples. In addition, the percentages of low scores were also determined when all possible combinations of two-test scores across the RAPID-II were considered in the overall normative sample. Our data showed that 59.4% subjects of the normative sample obtained at least one or more low score. With more than 9 test scores, this percentage was equal to 0% in the normative sample. Among all combinations of two

    In 2014, persons aged 13-29 years represented 23% of the U.S. population, yet accounted for 40% of diagnoses of human immunodeficiency virus (HIV) infection during the same year (1). During 2010-2014, the rates of diagnosis of HIV infection decreased among persons aged 15-19 years, were stable among persons aged 20-24 years, and increased among persons aged 25-29 years (1). However, these 5-year age groups encompass multiple developmental stages and potentially mask trends associated with the rapid psychosocial changes during adolescence through young adulthood. To better understand HIV infection among adolescents aged 13-17 years and young adults aged 18-29 years in the United States and identify ideal ages to target primary HIV prevention efforts, CDC analyzed data from the National HIV Surveillance System (NHSS)* using narrow age groups. During 2010-2014, rates of diagnosis of HIV infection per 100,000 population varied substantially among persons aged 13-15 years (0.7), 16-17 years (4.5), 18-19 years (16.5), and 20-21 years (28.6), and were higher, but less variable, among persons aged 22-23 years (34.0), 24-25 years (33.8), 26-27 years (31.3), and 28-29 years (28.7). In light of the remarkable increase in rates between ages 16-17, 18-19, and 20-21 years, and a recent study revealing that infection precedes diagnosis for young persons by an average of 2.7 years (2), these findings demonstrate the importance of targeting primary prevention efforts to persons aged <18 years and continuing through the period of elevated risk in their mid-twenties.

    We re-analyzed 39Ar-40Ar ages of Apollo lunar highland samples 15415 and 60015, two ferroan anorthosites analyzed previously in the 1970 s, with a more detailed approach and with revised decay constants. From these samples we carefully prepared 100-200 mesh mineral separates for analysis at the Noble Gas Laboratory at NASA-Johnson Space Center. The Ar-39-Ar-40 age spectra for 15415 yielded an age of 3851 +/- 38 Ma with 33-99% of Ar39 release, roughly in agreement with previously reported Ar-Ar ages. For 60015, we obtained an age of 3584 +/- 152 Ma in 23-98% of Ar39 release, also in agreement with previously reported Ar-Ar ages of approximately 3.5 Ga. Highland anorthosites like these are believed by many to be the original crust of the moon, formed by plagioclase floatation atop a magma ocean, however the Ar-Ar ages of 15415 and 60015 are considerably younger than lunar crust formation. By contrast, recently recovered lunar anorthosites such as Dhofar 489, Dhofar 908, and Yamato 86032 yield older Ar-Ar ages, up to 4.35 Ga, much closer to time of formation of the lunar crust. It follows that the Ar-Ar ages of the Apollo samples must have been reset by secondary heating, and that this heating affected highland anorthosites at both the Apollo 15 and Apollo 16 landing sites but did not affect lunar highland meteorites. One obvious consideration is that while the Apollo samples were collected from the near side of the moon, these lunar meteorites are thought to have originated from the lunar far side

    Data from National Health and Nutrition Examination Survey for 1999-2012 were used to evaluate factors that affect observed levels of blood cadmium (BCd) and urine cadmium (UCd) among former and current smokers aged 20-64 and ≥65 years. Adjusted levels (AGM) for BCd and UCd were higher among females as compared to males. The order of AGM for BCd by race/ethnicity for 20-64 years old was non-Hispanic white (NHW) < non-Hispanic black (NHB) and NHW > NHB for ≥65 years old. The order of AGMs for UCd for 20-64-year-old current smokers was NHW > NHB and NHW > NHB for former smokers. For 20-64-year-old current smokers, exposure to environmental tobacco smoke at home was associated with higher levels of BCd. Levels of both UCd and BCd increased with age, but the rate of increase was as much as seven times higher among ≥65 years old than 20-64 years old. For current smokers, the number of cigarettes smoked inside home was positively associated with the levels of BCd. For current smokers aged 20-64 years, the number of cigarettes smoked inside home was positively associated with the levels of UCd (p < 0.01), and the number of cigarettes smoked every day on the days they were smoked was also positively associated with the levels of UCd (p < 0.01). Among former smokers, levels of both UCd and BCd were positively associated (p < 0.1) with the number of cigarettes smoked per day at the time of quitting smoking and negatively associated with the time since smoking was quitted (p < 0.01).

    Chondrites have a complex chronology due to several variables affecting and operating on chondritic parent bodies such as radiogenic heating, pressure and temperature variation with depth, aqueous alteration, and shock or impact heating. Unbrecciated chondrites can record ages from 4.56 to 4.4 Ga that represent cooling in small parent bodies. Some brecciated chondrites exhibit younger ages (much less than 4 to 4.4 Ga) that may reflect the age of brecciation, disturbance, or shock and impact events (much less than 4 Ga). A unique R chondrite was recently found in the LaPaz Icefield of Antarctica - LAP 04840. This chondrite contains approximately 15% hornblende and trace amounts of biotite, making it the first of its kind. Studies have revealed an equigranular texture, mineral equilibria yielding equilibration near 650-700 C and 250-500 bars, hornblende that is dominantly OH-bearing (very little Cl or F), and high D/H ratios. To help gain a better understanding of the origin of this unique sample, we have measured the (40)Ar/(39)Ar age (LAP 04840 split 39).

    The Sangiran dome is the primary stratigraphic window for the Plio-Pleistocene deposits of the Solo basin of Central Jawa. The dome has yielded nearly 80 Homo erectus fossils, around 50 of which have known findspots. With a hornblende 40Ar/39Ar plateau age of 1.66 ± 0.04 mega-annum (Ma) reportedly associated with two fossils [Swisher, C.C., III, Curtis, G. H., Jacob, T., Getty, A. G., Suprijo, A. & Widiasmoro (1994) Science 263, 1118–1121), the dome offers evidence that early Homo dispersed to East Asia during the earliest Pleistocene. Unfortunately, the hornblende pumice was sampled at Jokotingkir Hill, a central locality with complex lithostratigraphic deformation and dubious specimen provenance. To address the antiquity of Sangiran H. erectus more systematically, we investigate the sedimentary framework and hornblende 40Ar/39Ar age for volcanic deposits in the southeast quadrant of the dome. In this sector, Bapang (Kabuh) sediments have their largest exposure, least deformation, and most complete tephrostratigraphy. At five locations, we identify a sequence of sedimentary cycles in which H. erectus fossils are associated with epiclastic pumice. From sampled pumice, eight hornblende separates produced 40Ar/39Ar plateau ages ranging from 1.51 ± 0.08 Ma at the Bapang/Sangiran Formation contact, to 1.02 ± 0.06 Ma, at a point above the hominin-bearing sequence. The chronological sequence of 40Ar/39Ar ages follows stratigraphic order across the southeast quadrant. An intermediate level yielding four nearly complete crania has an age of about 1.25 Ma.

    Sizes of horizontal wear facets of maxillary anterior teeth were studied longitudinally from the primary dentition at age five to the young adult dentition at the age of 18 years. By a planimetric method, we calculated the wear areas on dental casts taken at the ages of five, ten, 14, and 18 years from the dentition of 39 healthy, orthodontically untreated subjects with good morphological occlusion. For young adults, we also studied the association between the amount of wear and reported parafunctions, maximal bite force, salivary buffer capacity, salivary flow rate, and some cephalometric variables. Size of wear facets on all anterior teeth increased with age. Significant correlations were found between the total wear areas of the six anterior primary teeth at five years of age and those of their permanent successors at age 14 (r = 0.44) and 18 (r = 0.39). For an individual, tooth wear at five years of age was, however, of low predictive value for tooth wear in young adulthood, whereas tooth wear at 14 years of age predicted it well (r = 0.89). Highest correlations between tooth wear and background factors at 18 years of age were found for maximal anterior bite force (r = 0.44) and for the size of the gonial angle (r = -0.31). Wear of anterior teeth was not associated with reported parafunctions in young adulthood.

    This study examined the association between social media and sleep duration among Canadian students aged 11-20. Data from 5242 students were obtained from the 2015 Ontario Student Drug Use and Health Survey, a province-wide, school-based survey that has been conducted every two years since 1977. We measured the respondents' sleep duration against the recommended ranges of 9-11 h per night at 11-13 years of age, 8-10 h at 14-17 and 7-9 h per night for those aged 18 years or more. Overall, 36.4% of students met or exceeded the recommended sleep duration and 63.6% slept less than recommended, with 73.4% of students reporting that they used social media for at least one hour per day. After adjusting for various covariates, the use of social media was associated with greater odds of short sleep duration in a dose-response manner (p for linear trend <0.001). Odds ratios ranged from 1.82 for social media use of at least one hour per day to 2.98 for at least five hours per day. Greater use of social media was associated with shorter sleep duration in a dose-response fashion among Canadian students aged 11-20. ©2018 Foundation Acta Paediatrica.

    We assessed changes in age-specific prevalence of refractive error at the time of starting school, by comparing preschool and school age cohorts in Shanghai, China. A cross-sectional study was done in Jiading District, Shanghai during November and December 2013. We randomly selected 7 kindergartens and 7 primary schools, with probability proportionate to size. Chinese children (n = 8398) aged 3 to 10 years were enumerated, and 8267 (98.4%) were included. Children underwent distance visual acuity assessment and refraction measurement by cycloplegic autorefraction and subjective refraction. The prevalence of uncorrected visual acuity (UCVA), presenting visual acuity, and best-corrected visual acuity in the better eye of ≤20/40 was 19.8%, 15.5%, and 1.7%, respectively. Among those with UCVA ≤ 20/40, 93.2% could achieve visual acuity of ≥20/32 with refraction. Only 28.7% (n = 465) of children with UCVA in the better eye of ≤20/40 wore glasses. Prevalence of myopia (spherical equivalent ≤-0.5 diopters [D] in at least one eye) increased from 1.78% in 3-year-olds to 52.2% in 10-year-olds, while prevalence of hyperopia (spherical equivalent ≥+2.0 D) decreased from 17.8% among 3-year-olds to 2.6% by 10 years of age. After adjusting for age, attending elite "high-level" school was statistically associated with greater myopia prevalence. The prevalence of myopia was lower or comparable to that reported in other populations from age 3 to 5 years, but increased dramatically after 6 years, consistent with a strong environmental role of schooling on myopia development.

    We aimed to see whether primary percutaneous coronary intervention (PCI) benefits for ST-segment elevation myocardial infarction (STEMI) in the aged could be validated. Primary PCI benefits in elderly patients with STEMI remain uncertain. We reviewed 947 consecutive patients treated with primary PCI for STEMI: 331 were aged ≥75 years (older) and 616 <75 years (younger). The older group had higher percentage of renal insufficiency (7.9% vs. 3.1%, P = 0.0010), prior stroke (9.4% vs. 3.9%, P = 0.0006), 30-day mortality rate (7.6% vs. 3.9%, P = 0.015), and cardiac mortality rate (6.6% vs. 3.7%, P = 0.045). Successful reperfusion rates were similarly high in both groups (90.0% and 92.7%, P = 0.16), despite the higher proportion of patients with door-to-balloon time >90 min (15% vs. 8.4%, P = 0.0016) in older patients. Successful compared with unsuccessful PCI significantly decreased 30-day mortality rates in the older group (6.0% vs. 21%, P = 0.0018) and in the younger group (2.8% vs. 18%, P < 0.0001). When reperfusion was successful, cardiac mortality rate in older patients was not significantly greater than in younger patients (5.4% vs. 2.8%, P = 0.057). By multivariate analysis, unsuccessful reperfusion independently predicted 30-day mortality (odds ratio, 4.04; 95% confidence interval, 1.79-9.12; P = 0.0008), whereas age ≥75 years (odds ratio, 1.00; 95% confidence interval, 0.41-2.41; P = 0.99) and door-to-balloon time >90 min (odds ratio, 1.78; 95% confidence interval, 0.76-4.20; P = 0.19) did not. Pre-existing comorbidities characterize older patients developing STEMI. Aggressive PCI in older patients improves prognosis, and short door-to-balloon time is an important parameter conditioning the prognosis. Copyright © 2011 Wiley Periodicals, Inc.

    We present new 40Ar/ 39Ar ages and paleomagnetic data for São Miguel island, Azores. Paleomagnetic samples were obtained for 34 flows and one dike; successful mean paleomagnetic directions were obtained for 28 of these 35 sites. 40Ar/ 39Ar age determinations on 12 flows from the Nordeste complex were attempted successfully: ages obtained are between 0.78 Ma and 0.88 Ma, in contrast to published K-Ar ages of 1 Ma to 4 Ma. Our radiometric ages are consistent with the reverse polarity paleomagnetic field directions, and indicate that the entire exposed part of the Nordeste complex is of a late Matuyama age. The duration of volcanism across São Miguel is significantly less than previously believed, which has important implications for regional melt generation processes, and temporal sampling of the geomagnetic field. Observed stable isotope and trace element trends across the island can be explained, at least in part, by communication between different magma source regions at depth. The 40Ar/ 39Ar ages indicate that our normal polarity paleomagnetic data sample at least 0.1 Myr (0-0.1 Ma) and up to 0.78 Myr (0-0.78 Ma) of paleosecular variation and our reverse polarity data sample approximately 0.1 Myr (0.78-0.88 Ma) of paleosecular variation. Our results demonstrate that precise radiometric dating of numerous flows sampled is essential to accurate inferences of long-term geomagnetic field behavior. Negative inclination anomalies are observed for both the normal and reverse polarity time-averaged field. Within the data uncertainties, normal and reverse polarity field directions are antipodal, but the reverse polarity field shows a significant deviation from a geocentric axial dipole direction.

    material is responsible for the dispersion of ages. In any case the aphanitic melts do not appear to be Serenitatis products. Our age for the Serenitatis impact shows, on the basis of the isotopic age evidence alone, that Serenitatis is greater than 20-25 Ma and probably greatr than 55-60 Ma older than Imbrium (less than or equal to 3870 Ma and probably less than or equal to 3836 Ma (Dalrymple and Ryder, 19931). Noritic granulite sample 78527 has a plateau age of 4146 +/- 17 Ma, representing a minimum age for cooling of this sample in the early lunar crust. So far there is no convincing evidence in the lunar melt rock record for basin-forming impacts significantly older than 3.9 Ga.

  15. A closer look at 40Ar/39Ar systematics of illite, recoil, retention ages, total gas ages, and a new correction method

    2013-12-01

    One of the fundamentals of 40Ar-39Ar systematics of illite considers the effects of 39Ar recoil (ejection of 39Ar from tiny illite crystallites during the nuclear reaction 39K(n,p)39Ar), for which sample vacuum encapsulation prior to irradiation has been used since the 1990's. This technique separately measures the fraction of recoiled 39Ar and the Ar (39Ar and 40Ar) retained within illite crystals as they degas during step heating in vacuum. Total-gas ages (TGA) are calculated by using both recoiled and retained argon, while retention ages (RA) only involve retained Ar. Observations in numerous natural examples have shown that TGA fit stratigraphic constraints of geological processes when the average illite crystallite thickness (ICT) is smaller than 10nm, and that RA better matches these constrains for larger ICTs. Illite crystals with ICT >50nm show total gas and retention ages within a few My and they are identical, within analytical error, when ICT exceeds 150nm. We propose a new age correction that takes into account the average ICT and corresponding recoil for a sample , with such corrected ages (XCA) lying between the TGA and RA end-member ages. We apply this correction to samples containing one generation of illite and it particularly affects illite populations formed in the anchizone, with typical ICT values between 10-40nm. We analyzed bentonitic samples (S1, S2 and S3) from sites in Cretaceous carbonates in the front of the Monterrey salient in northern Mexico. Four size fractions (<0.05, 0.05-0.2, 0.2-1 & 1-2 μm) were separated, analyzed with XRD and dated by Ar-Ar. XRD analysis provides mineralogic characterization, illite polytype quantification, and illite crystallite thickness (ICT) determination using half-height peak width (illite crystallinity) and the Scherrer equation. All samples contain illite as the main mineral phase, ICT values between 8-27nm, from fine to coarser grain size fractions. Ages show a range in TGA among the different size

    We aimed to evaluate the incidence of type 1 diabetes mellitus in children <15 years of age (yr) in the Auckland region (New Zealand) over 20 years (1990-2009). We performed a retrospective review of all patients <15 yr diagnosed with type 1 diabetes, from an unselected complete regional cohort. There were 884 new cases of type 1 diabetes, and age at diagnosis rose from 7.6 yr in 1990/1 to 8.9 yr in 2008/9 (r(2) = 0.31, p = 0.009). There was a progressive increase in type 1 diabetes incidence among children <15 yr (p<0.0001), reaching 22.5 per 100,000 in 2009. However, the rise in incidence did not occur evenly among age groups, being 2.5-fold higher in older children (10-14 yr) than in the youngest group (0-4 yr). The incidence of new cases of type 1 diabetes was highest in New Zealand Europeans throughout the study period in all age groups (p<0.0001), but the rate of increase was similar in New Zealand Europeans and Non-Europeans. Type 1 diabetes incidence and average annual increase were similar in both sexes. There was no change in BMI SDS shortly after diagnosis, and no association between BMI SDS and age at diagnosis. There has been a steady increase in type 1 diabetes incidence among children <15 yr in Auckland over 20 years. Contrary to other studies, age at diagnosis has increased and the greatest rise in incidence occurred in children 10-14 yr. There was little change in BMI SDS in this population, providing no support for the 'accelerator hypothesis'.

    Current guidelines recommend colon cancer screening for persons aged over 50 years. However, there are few data on colorectal cancer screening in 40- to 49-year-olds. This study assessed the prevalence and risk factors of colorectal neoplasms in 40- to 49-year-old Koreans. We analyzed the results of screening colonoscopies of 6680 persons 40-59 years of age (2206 aged 40-49 and 4474 aged 50-59 years). The prevalence of overall and advanced neoplasms in the 40- to 49-year age group was lower than in the 50- to 59-year age group (26.7% and 2.4% vs 37.8% and 3.5%, respectively). However, the prevalence of overall and advanced neoplasms increased to 39.1% and 5.4%, respectively, in 45- to 49-year-old individuals with metabolic syndrome. In the 40- to 49-year age group, age, current smoking, and metabolic syndrome were associated with an increased risk of advanced neoplasms (odds ratio [OR] 1.16, 95% confidence interval [CI] 1.04-1.30; OR 3.12, 95% CI 1.20-8.12; and OR 2.00, 95% CI 1.09-3.67, respectively). Individuals aged 40-49 years had a lower prevalence of colorectal neoplasms than those aged 50-59 years, but some 40- to 49-year-olds showed a similar prevalence to those aged 50-59 years. Age, current smoking habits, and metabolic syndrome are associated with an increased risk of advanced neoplasms in subjects aged 40-49 years. Further studies are needed to stratify the risks of colon cancer and guide targeted screening in persons younger than 50 years old. © 2016 Journal of Gastroenterology and Hepatology Foundation and John Wiley & Sons Australia, Ltd.

    Undernutrition among children is a major public health concern worldwide, more prevalent in Asia and Africa. It manifests itself in various forms such as wasting or stunting or underweight and retards physical and mental development, increases susceptibility to infection, and reduces educational attainment and productivity. The present study was undertaken to assess the level of wasting, stunting, and underweight and determine its associates among slum children of 3-9 years of age, residing in Bhubaneswar city, India. After obtaining informed consent, a total of 249 children from 249 households were studied and their parents/guardians were interviewed to collect all relevant information. 23.3%, 57.4%, and 45.4% of children were found to have wasting, stunting, and underweight, respectively. Variables like birth order of child, period of initiation of breastfeeding and mother's education were found to be strong predictors of wasting, whereas toilet facility in household and practice of drinking water storage were significantly associated with stunting among slum children as revealed in multiple regression analysis. Thus, a multipronged approach is needed such as giving priority to improve education for slum community especially for women, creating awareness regarding benefits of early initiation of breastfeeding, small family size, and proper storage of drinking water, and providing toilet facility in slum households which could improve the nutritional status of slum children.

    Mitral valve repair is considered the gold standard in surgery of degenerative mitral valve insufficiency (MVI), but the long-term results (>20 years) are unknown. We reviewed the first 162 consecutive patients who underwent mitral valve repair between 1970 and 1984 for MVI due to nonrheumatic disease. The cause of MVI was degenerative in 146 patients (90%) and bacterial endocarditis in 16 patients (10%). MVI was isolated or, in 18 cases, associated with tricuspid insufficiency. The mean age of the 162 patients (104 men and 58 women) was 56+/-10 years (age range 22 to 77 years). New York Heart Association functional class was I, II, III, and IV in 2%, 39%, 52%, and 7% of patients, respectively. The mean cardiothoracic ratio was 0.58+/-0.07 (0.4 to 0.8), and 72 (45%) patients had atrial fibrillation. Valve analysis showed that the main mechanism of MVI was type II Carpentier's functional classification in 152 patients. The leaflet prolapse involved the posterior leaflet in 93 patients, the anterior leaflet in 28 patients, and both leaflets in 31 patients. Surgical technique included a Carpentier's ring annuloplasty in all cases, a valve resection in 126 patients, and shortening or transposition of chordae in 49 patients. During the first postoperative month, there were 3 deaths (1.9%) and 3 reoperations (2 valve replacements and 1 repeat repair [1.9%]). Six patients were lost to follow-up. The remaining 151 patients with mitral valve repair were followed during a median of 17 years (range 1 to 29 years; 2273 patient-years). The 20-year Kaplan-Meier survival rate was 48% (95% CI 40% to 57%), which is similar to the survival rate for a normal population with the same age structure. The 20-year rates were 19.3% (95% CI 11% to 27%) for cardiac death and 26% (95% CI 17% to 35%) for cardiac morbidity/mortality (including death from a cardiac cause, stroke, and reoperation). During the 20 years of follow-up, 7 patients were underwent surgery at 3, 7, 7, 8, 8, 10, or 12

  20. Single-crystal 40Ar/39Ar incremental heating reveals bimodal sanidine ages in the Bishop Tuff

    The 650 km3 Bishop Tuff (BT) is among the most studied volcanic deposits because it is an extensive marker bed deposited just after the Matuyama-Brunhes boundary. Reconstructions of the vast BT magma reservoir from which high-silica rhyolite erupted have long influenced thinking about how large silicic magma systems are assembled, crystallized, and mixed. Yet, the longevity of the high silica rhyolitic melt and exact timing of the eruption remain controversial due to recent conflicting 40Ar/39Ar sanidine vs. SIMS and ID-TIMS U-Pb zircon dates. We have undertaken 21 40Ar/39Ar incremental heating ages on 2 mm BT sanidine crystals from pumice in 3 widely separated outcrops of early-erupted fall and flow units. Plateau ages yield a bimodal distribution: a younger group has a mean of 766 ka and an older group gives a range between 772 and 782 ka. The younger population is concordant with the youngest ID-TIMS and SIMS U-Pb zircon ages recently published, as well as the astronomical age of BT in marine sediment. Of 21 crystals, 17 yield older, non-plateau, steps likely affected by excess Ar that would bias traditional 40Ar/39Ar total crystal fusion ages. The small spread in older sanidine ages, together with 25+ kyr of pre-eruptive zircon growth, suggest that the older sanidines are not partially outgassed xenocrysts. A bimodal 40Ar/39Ar age distribution implies that some fraction of rhyolitic melt cooled below the Ar closure temperature at least 10 ky prior to eruption. We propose that rapid "thawing" of a crystalline mush layer released older crystals into rhyolitic melt from which sanidine also nucleated and grew immediately prior to the eruption. High precision 40Ar/39Ar dating can thus provide essential information on thermo-physical processes at the millenial time scale that are critical to interpreting U-Pb zircon age distributions that are complicated by large uncertainties associated with zircon-melt U-Th systematics.

    The majority of tobacco use emerges in individuals before they reach 21 years of age, and many adult distributors of tobacco to youths are young adults aged between 18 and 20 years. Raising the tobacco sales minimum age to 21 years across the United States would decrease tobacco retailer and industry sales by approximately 2% but could contribute to a substantial reduction in the prevalence of youths' tobacco use and dependency by limiting access.

    increasing number of persons reach very high age but few studies have investigated their drug use patterns. to compare drug use among persons with Alzheimer's disease (AD) aged ≥90 years to persons without AD with similar age and to younger persons with AD. register-based data were from the MEDALZ cohort including all community-dwelling persons diagnosed with AD 2005-11 in Finland. They were identified from Special Reimbursement register. One comparison person without AD was matched with age-, gender- and region of residence. Persons with AD were divided to those aged ≥90 years (N = 3,319) and <90 years (N = 63,896) at the time of AD diagnoses. Drug use was analysed during a 6-month period after AD diagnosis. Logistic regression models were constructed to compare prevalence of drug use. compared to comparison persons without AD with similar age, persons with AD aged ≥90 years were more likely to use antipsychotics (comorbidity adjusted odds ratio [aOR] 4.84, 95% CI 4.07-5.75; CI, confidence intervals) and antidepressants (aOR 2.45, 95% CI 2.14-2.80). In addition, persons with AD used more likely preventive drugs such as statins (aOR 1.20, 95% CI 1.04-1.38) and bisphosphonates (aOR 1.33, 95% CI 1.13-1.57). Compared to younger persons with AD, those aged ≥90 years were more likely to use psychotropic drugs (55.6% vs. 48.4%, aOR 1.30, 95% CI 1.21-1.39), including antipsychotics (aOR 1.40, 95% CI 1.28-1.52) and BZDRs (aOR 1.34, 95% CI 1.25-1.45). the vulnerable oldest persons with AD receive a substantial burden of psychotropics. © The Author 2016.

    Motor vehicle accidents are the leading cause of death among youths and young adults aged 16-25 years in the United States (1). The prevalence of drinking and driving among high school students aged 16-19 years has declined by 54%, from 22.3% in 1991 to 10.3% in 2011 (2). However, the prevalence of weekend nighttime driving under the influence of marijuana (based on biochemical assays) among drivers aged ≥16 years has increased by 48%, from 8.6% in 2007 to 12.6% in 2013-2014 (3). Use of marijuana alone and in combination with alcohol has been shown to impair driving abilities (4-9). This report provides the most recent self-reported national estimates of driving under the influence of alcohol, marijuana, and alcohol and marijuana combined among persons aged 16-25 years, using data from the Substance Abuse and Mental Health Services Administration (SAMHSA) National Survey on Drug Use and Health (NSDUH) from 2002-2014. Prevalence data on driving under the influence of both substances were examined for two age groups (16-20 years and 21-25 years) and by sex and race/ethnicity. During 2002-2014, the prevalence of driving under the influence of alcohol alone significantly declined by 59% among persons aged 16-20 years (from 16.2% in 2002 to 6.6% in 2014; p<0.001) and 38% among persons 21-25 years (from 29.1% in 2002 to 18.1% in 2014; p<0.001). In addition, the prevalence of driving under the influence of alcohol and marijuana combined significantly declined by 39%, from 2.3% in 2002 to 1.4% in 2014 (p<0.001) among persons aged 16-20 years and from 3.1% in 2002 to 1.9% in 2014 (p<0.001) among persons aged 21-25 years. The prevalence of driving under the influence of marijuana alone declined 18%, from 3.8% in 2002 to 3.1% in 2014 (p = 0.05) only among persons aged 16-20 years.

    Background We aimed to evaluate the incidence of type 1 diabetes mellitus in children <15 years of age (yr) in the Auckland region (New Zealand) over 20 years (1990–2009). Methods We performed a retrospective review of all patients <15 yr diagnosed with type 1 diabetes, from an unselected complete regional cohort. Results There were 884 new cases of type 1 diabetes, and age at diagnosis rose from 7.6 yr in 1990/1 to 8.9 yr in 2008/9 (r2 = 0.31, p = 0.009). There was a progressive increase in type 1 diabetes incidence among children <15 yr (p<0.0001), reaching 22.5 per 100,000 in 2009. However, the rise in incidence did not occur evenly among age groups, being 2.5-fold higher in older children (10–14 yr) than in the youngest group (0–4 yr). The incidence of new cases of type 1 diabetes was highest in New Zealand Europeans throughout the study period in all age groups (p<0.0001), but the rate of increase was similar in New Zealand Europeans and Non-Europeans. Type 1 diabetes incidence and average annual increase were similar in both sexes. There was no change in BMI SDS shortly after diagnosis, and no association between BMI SDS and age at diagnosis. Conclusions There has been a steady increase in type 1 diabetes incidence among children <15 yr in Auckland over 20 years. Contrary to other studies, age at diagnosis has increased and the greatest rise in incidence occurred in children 10–14 yr. There was little change in BMI SDS in this population, providing no support for the ‘accelerator hypothesis’. PMID:22389717

    The generally young K/Ar and 40Ar/39Ar ages of CM chondrites made us wonder whether carbonaceous xenoliths (CMX) entombed in Howardite–Eucrite–Diogenite (HED) meteorites might retain more radiogenic 40Ar than do ‘free-range’ CM-chondrites. To find out, we selected two HED breccias with carbonaceous inclusions in order to compare the 40Ar/39Ar release patterns and ages of the inclusions with those of nearby HED material. Carbonaceous inclusions (CMXs) in two HED meteorites lost a greater fraction of radiogenic 40Ar than did surrounding host material, but a smaller fraction of it than did free-range CM-chondrites such as Murchison or more heavily altered ones. Importantly, however, the siting of the CMXs in HED matrix did not prevent the 40Ar loss of about 40 percent of the radiogenic 40Ar, even from phases that degas at high laboratory temperatures. We infer that carbonaceous asteroids with perihelia of 1 astronomical unit probably experience losses of at least this size. The usefulness of 40Ar/39Ar dating for samples returned from C-type asteroids may hinge, therefore, on identifying and analyzing separately small quantities of the most retentive phases of carbonaceous chondrites.

    Homo erectus was the first human lineage to disperse widely throughout the Old World, the only hominin in Asia through much of the Pleistocene, and was likely ancestral to H. sapiens. The demise of this taxon remains obscure because of uncertainties regarding the geological age of its youngest populations. In 1996, some of us co-published electron spin resonance (ESR) and uranium series (U-series) results indicating an age as young as 35-50 ka for the late H. erectus sites of Ngandong and Sambungmacan and the faunal site of Jigar (Indonesia). If correct, these ages favor an African origin for recent humans who would overlap with H. erectus in time and space. Here, we report (40)Ar/(39)Ar incremental heating analyses and new ESR/U-series age estimates from the "20 m terrace" at Ngandong and Jigar. Both data sets are internally consistent and provide no evidence for reworking, yet they are inconsistent with one another. The (40)Ar/(39)Ar analyses give an average age of 546±12 ka (sd±5 se) for both sites, the first reliable radiometric indications of a middle Pleistocene component for the terrace. Given the technical accuracy and consistency of the analyses, the argon ages represent either the actual age or the maximum age for the terrace and are significantly older than previous estimates. Most of the ESR/U-series results are older as well, but the oldest that meets all modeling criteria is 143 ka+20/-17. Most samples indicated leaching of uranium and likely represent either the actual or the minimum age of the terrace. Given known sources of error, the U-series results could be consistent with a middle Pleistocene age. However, the ESR and (40)Ar/(39)Ar ages preclude one another. Regardless, the age of the sites and hominins is at least bracketed between these estimates and is older than currently accepted.

    Background Whether and how sex and age affect bariatric-surgery outcome is poorly understood. Estrogens regulate body composition in women and animals and increased weight loss in a rodent model of gastric bypass, suggesting that premenopausal women may lose more weight following bariatric surgery. Methods 1,356 female gastric-bypass or gastric-banding patients were retrospectively grouped as 20-45 y old (presumptively premenopausal; n = 1199) and 55-65 y old (presumptively postmenopausal; n = 157). Mixed-model ANCOVA followed by Bonferroni-corrected t-tests were used to categorically test the effect of age on percent excess body weight loss (%EBWL) at 1 and 2 y post-surgery, controlling for preoperative EBW and surgery type. Age effects were also tested dimensionally in all women and in 289 male patients. Results 20-45 y-old women showed greater %EBWL 1 and 2 y post-surgery than 55-65 y-old women (p’s < 0.0005). No age effect was detected in 20-25 vs. 30-35, 30-35 vs. 40-45, or 20-25 vs. 40-45 y-old women (p’s > 0.2) This age effect was detected only after gastric banding, with 20-45 y-old women losing ~7 kg more than 55-65 y-old women after 2 y. Dimensional analysis confirmed a significant inverse effect of age on bariatric surgery outcome in women, but did not detect any effect in men. Conclusions Results indicate that 55-65 y-old women lose less weight than 20-45 y-old women in the initial 2 y after bariatric surgery, especially gastric banding; this may be mediated by age- or menopause-associated changes in physical activity, energy expenditure, or energy intake.

    Age is a major prognostic factor in differentiated thyroid cancer (DTC). It is not clear if paediatric DTC has a different histopathological profile and outcome than DTC in adult patients <45 years of age. To assess whether DTC in children and adolescents differs from young age group by comparing paediatric DTC (age20) with DTC in patients >20 to <45 years of age. We studied all cases of paediatric DTC seen during the period 1998-2011. We compared this group with a large sample of 213 consecutive adult patients in the age group >20 to <45 years seen during the period 1998-1999 in terms of their pathological features, extent of the disease and long-term outcome. Both groups were managed by the same team at a single institution. A total of 310 DTC were studied including 97 paediatric patients [median age 17 years (range, 8-20)] and 213 young adult patients [median age 33 years (range, 20·5-44·9)]. There was no difference in gender distribution, tumour subtypes, size and tumour multifocality, but there was a significantly higher rate of extrathyroidal extension [40/75 (53·3%) vs 81/213 (38·0%), P = 0·03], lymph node [57/73 (78%) vs 102/183 (55·7%), P < 0·0001] and distant metastases [16/97 (16·5%) vs 8/213 (3·8%), P < 0·0001] in the paediatric than the adult groups. Kaplan-Meier analysis showed a higher risk of persistent/recurrent disease in the paediatric group than adults (log-rank test 0·03). However, there was no mortality secondary to DTC in both groups. Paediatric DTC is distinct from DTC in the young adults (age >20 to <45 years). It is characterized by a higher rate of extrathyroidal extension, lymph node and distant metastases and a higher risk of persistent/recurrent DTC. © 2015 John Wiley & Sons Ltd.

    Human immunodeficiency virus (HIV) infection was the second most common cause of death, after injuries of external causes, among young adults from Bucaramanga in 2013. To establish the extent of knowledge on HIV mechanisms of transmission prevention strategies among schoolchildren in the age range of 13 to 20 years old from poor districts of Bucaramanga. Cross-sectional study among randomly selected schoolchildren using a self-administered anonymous survey. For analysis, each outcome measure and binomial models for the association of answers by age, gender, education level and past sexual experience were described. A survey was administered to 729 students (57% were girls); 50.6% of boys and 31.1% of girls reported having had sexual intercourse. Also, 58.6% stated that a healthy-looking person can have HIV. Besides, 69.1% indicated that HIV can be transmitted during pregnancy; 39.2%, during delivery; 37.7%, through breastfeeding; 79.7%, through needle sharing; 29.5%, by sharing food with someone who has HIV; and 31.7%, by mosquito bites. In addition, 70.6% considered that they could prevent HIV by abstaining from having sexual relationships; 67.5%, by having a single partner; and 80.0%, by wearing condoms correctly. The proportion of adequate answers was not related to a higher education level, age, gender or sexual experience. The quality of knowledge regarding HIV mechanisms of transmission and prevention is very poor, in spite of curricular contents providing sex education. It was observed that knowledge was not greater among those with higher education levels. Sociedad Argentina de Pediatría.

    This study was planned to assess the dental caries status among disabled children as dental health is an integral part of general body health and this group is deprived of health care needs. A sample of 310 disabled children was gathered including 195- Hearing impaired, 115 - blind. Of which 226 were males and 84 were females. A study questionnaire was prepared to include demographic information and WHO oral health assessment form (1997) to record dental caries status.Data was analysed using student's test and ANOVA test was used at p≤0.05. The overall mean for DMFT scores for males and females was 2.11 (1.753) and 1.75 (1.275) respectively. Similarly overall mean for dft was 0.31 (0.254) for males and 0.27 (0.143) for females. Mean DMFT of blind students was more as compared to hearing impaired ones as 2.16 (2.005) and 1.80 (1.264) respectively. Age factor showed a significant increase in the mean DMFT scores with advancing age at p ≤ 0.001. Overall mean scores of caries was very high and it increased with increasing age. Blind children experienced more caries then hearing impaired children in permanent, whereas it was opposite in primary dentition. So there is urgent need of both comprehensive and incremental dental care for this subgroup of population. How to cite the article: Sanjay V, Shetty SM, Shetty RG, Managoli NA, Gugawad SC, Hitesh D.

    To treat children born small for gestational age (SGA) with severe short stature, treatment with growth hormone (GH) has been approved in the USA, Europe, and Japan, but no population-based studies have reported their prevalence. The aims of this study were to investigate the prevalence of SGA and short stature in children born SGA who qualify for GH treatment at 3 years of age in a Japanese population. A population-based study was conducted in Kobe, Japan with 27 228 infants who were born between 2006 and 2008 and followed until 3 years of age. Prevalence of birthweight (BW) or birth length (BL) ≤ -2.0 standard deviation scores (SDS) for gestational age (GA; definition of SGA) was calculated. Short children born SGA who qualify for GH treatment at 3 years of age were estimated using the following criteria: BW and BL below the 10th percentile for GA, BW or BL ≤ -2.0 SDS for GA, and 2.5 SDS below the mean height for age. The prevalence of SGA was 3.5%. The estimated prevalence of short stature in children born SGA who met the criteria for GH treatment was 0.06%. The prevalence in infants born <34 weeks (0.39%) was significantly higher than that in infants born 34-41 weeks GA (0.05%, P = 0.02). The prevalence of SGA and short stature in children born SGA who qualify for GH treatment is approximately 1 of 30 infants and 1 of 1800 children, respectively. The risk is increased when children are born <34 weeks GA. © 2015 Japan Pediatric Society.

    In 1964, The Melbourne Asthma Study was established to describe the spectrum and natural history of childhood asthma. To describe the clinical and lung function outcome of childhood asthma to the age of 50 years. Subjects were invited to complete an interviewer-administered questionnaire, skin prick testing, and measurement of lung function from the age of 7 years to the age of 50 years at 7-year intervals. Of 458 survivors (from the original 484 subjects at recruitment), 346 subjects (76%) participated, of whom, 197 completed lung function measurement. Asthma remission at the age of 50 years was 64% in those with wheezy bronchitis, 47% for those with persistent asthma, and 15% for those with severe asthma in childhood. Multivariable analysis identified severe asthma in childhood (odds ratio [OR] 11.9 [95% CI, 3.4-41.8]), female sex (OR 2.0 [95% CI, 1.1-3.6]), and childhood hay fever (OR 2.0 [95% CI, 1.0-4.0]) as risk factors for "current asthma" at age 50 years. There was no evidence of a difference in the rate of decline in FEV1 (mL/y, 95% CI) between the severe asthma group (15 mL/y [95% CI, 9-22 mL/y]) and all the other recruitment groups: control (16 mL/y [95% CI, 12-20 mL/y]), mild wheezy bronchitis (14 mL/y [95% CI, 8-19 mL/y]), wheezy bronchitis (16 mL/y [95% CI, 11-20 mL/y]), and persistent asthma (19 mL/y [95% CI, 13-24 mL/y]). The clinical and lung function outcome in adult life is strongly determined by asthma severity in childhood. The reduced lung function seen in adults is established in childhood and does not appear to decline more rapidly in adult years despite continuing symptoms.

    Background The aim of this study was to determine whether eyebrow and eyelash whitening is an effective parameter in age estimation. Material/Methods We evaluated 1545 patients. Age groups were 1–10, 11–20, 21–30, 31–40, 41–50, 51–60, 61–70, 71–80, and 81–90 years. Level of whitening was categorized as level 0: no whitening, level 1: 1–3 strands, level 2: 3–10 strands, level 3: 10 strands–2/3 whitening, level 4: >3/4 whitening. Results Mean age was 42.39±20.01. While there was no eyebrow whitening in 87% of the subjects, level 4 whitening of eyebrows was observed in 0,8% of the subjects. There was no eyelash whitening in 97,7% of the subjects and no level 4 eyelash whitening was detected in any subject. Men had significantly more level 1, 2, 3, and 4 eyebrow whitening compared with women. There was no gender difference in terms of eyelash whitening level. There was no eyebrow and eyelash whitening in subjects age 1–40 years; whitening began in the 41–50 years age group and increased with age in other groups. Mean age was 39.59±19.63 years in subjects with no eyebrow whitening; 59 years in level 1, 61 years in level 2, 63 years in level 3, and 69 years in level 4 eyebrow whitening. Mean age was 41.85±19.87 in subjects with no eyelash whitening; and 63.57±10.75 in those with whitening. Conclusions Particularly after 41–50 years of age, level of eyebrow and eyelash whitening may be among a useful age estimation parameter. PMID:24448310

    Objective To clarify if older pregnant women were more likely to have adverse perinatal outcomes when compared to women at an ideal age to have a child. Methods The groups were divided according to age groups: under 20 years, ≥20 to <40 years, and ≥40 years. Results During the period from January 1st, 2008, to December 31st, 2008, there were 76 births from patients younger than 20 years and 91 births from patients aged 40 years or over. To form a third group with intermediate age, the data of 92 patients aged 20 to 40 years were obtained, totaling 259 patients. Patients aged 40 or older had a statistically greater number of cesarean sections and less use of forceps or normal deliveries (p<0.001). The use of spinal anesthesia was statistically higher among those aged 40 years or more (p<0.001). The frequency of male newborns was statistically higher in older patients, a group with statistically fewer first pregnancies (p<0.001). The frequency of premature newborns was statistically higher in patients aged 40 years or more (p=0.004). Conclusion It is crucial to give priority to aged women, so that prenatal care will be appropriate, minimizing maternal complications and improving perinatal outcomes in this unique group.

    ABSTRACT Objective: Our aim was to analyze the effectiveness of oxybutynin for hyperhidrosis treatment in patients over 40 years. Methods: Eighty-seven patients aged over 40 years were divided into two groups. One group consisted of 48 (55.2%) patients aged between 40 and 49 years, and another was composed of 39 (44.8%) patients aged over 50 years (50 to 74 years). A comparative analysis of Quality of Life and level of hyperhidrosis between the groups was carried out 6 weeks after a protocol treatment with oxybutynin. A validated clinical questionnaire was used for evaluation. Results: In the younger age group, 75% of patients referred a “partial” or “great” improvement in level of hyperhidrosis after treatment. This number was particularly impressive in patients over 50 years, in which 87.2% of the cases demonstrated similar levels of improvement. Over 77% of patients in both groups demonstrated improvement in Quality of Life. Excellent outcomes were observed in older patients, in which 87.1% of patients presented “slightly better” (41%) or “much better” (46.1%) improvement. Conclusion: Patients aged over 40 years with hyperhidrosis presented excellent results after oxybutynin treatment. These outcomes were particularly impressive in the age group over 50 years, in which most patients had significant improvement in Quality of Life and in level of hyperhidrosis. PMID:24728245

    Using data from National Health and Nutrition Examination Survey for the period 2003-2012, the objective of this study was to evaluate trends in blood lead levels (BLL) among adults aged 20-64 years (adults) and seniors aged ≥65 years (seniors). In addition, the contribution of other factors like gender, race/ethnicity, smoking, and exposure to secondhand smoke at home in explaining variability in BLL was also evaluated by fitting regression models with log10 transformed values of BLL as dependent variables. BLL decreased over 2003-2012 (p < 0.01). Irrespective of gender, race/ethnicity, and smoking status, seniors were found to have higher BLL than adults. Based on the magnitude of differences between the 5th and 95th percentiles, variability in the levels of blood lead was found to be substantially higher among seniors than among adults. Males had statistically significantly higher adjusted BLL than females (2.32 vs. 1.76 μg/dL for seniors, p < 0.01 and 1.66 vs. 1.13 μg/dL for adults, p < 0.01). Non-Hispanic whites had statistically significantly lower adjusted BLL than non-Hispanic blacks (1.99 vs. 2.42 μg/dL for seniors, p < 0.01 and 1.22 vs. 1.42 μg/dL for adults, p < 0.01). When compared with non-smokers, smokers had statistically significantly higher BLL (2.19 vs. 1.86 μg/dL for seniors, p < 0.01 and 1.54 vs. 1.22 μg/dL for adults, p < 0.01). Non-obese had statistically significantly higher BLL than obese individuals (2.11 vs. 1.93 μg/dL for seniors, p < 0.01 and 1.48 vs. 1.27 μg/dL for adults, p < 0.01). Exposure to secondhand smoke at home (SHS) was associated with statistically significantly higher BLL than when there was no exposure to SHS (β = 0.0683, p = 0.03 for seniors; β = 0.034, p = 0.034, p < 0.01 for adults).

    Chromatic contrast sensitivity may be a more sensitive measure of an individual's visual function than achromatic contrast sensitivity. Here, the first aim was to quantify individual- and age-related variations in chromatic contrast sensitivity to a range of spatial frequencies for stimuli along two complementary directions in color space. The second aim was to examine whether polymorphisms at specific amino acid residues of the L- and M-opsin genes (OPN1LW and OPN1MW) known to affect spectral tuning of the photoreceptors could influence spatio-chromatic contrast sensitivity. Chromatic contrast sensitivity functions were measured in 50 healthy individuals (20-71 years) employing a novel pseudo-isochromatic grating stimulus. The spatio-chromatic contrast sensitivity functions were found to be low pass for all subjects, independent of age and color vision. The results revealed a senescent decline in spatio-chromatic contrast sensitivity. There were considerable between-individual differences in sensitivity within each age decade for individuals 49 years old or younger, and age did not predict sensitivity for these age decades alone. Forty-six subjects (including a color deficient male and eight female carriers) were genotyped for L- and M-opsin genes. The Ser180Ala polymorphisms on the L-opsin gene were found to influence the subject's color discrimination and their sensitivity to spatio-chromatic patterns. The results expose the significant role of neural and genetic factors in the deterioration of visual function with increasing age. Copyright © 2015 Elsevier Ltd. All rights reserved.

  4. 40Ar-39Ar age clustering in the active phonolitic Cadamosto Seamount (Cape Verdes): Indications for periodic magmatic activity

    The Cape Verde archipelago is situated 400-800 km off the west coast of Africa and is comprised of a northern and southern chain of islands and seamounts. Morphological observations and previous radiometric dating of the islands indicate a slow age progression, over 22 Ma, from east to west (Holm et al. 2008). We present the first radiometric ages for Cadamosto Seamount, which is composed of complex evolved volcanics and is situated at the southwestern tip of the Cape Verde archipelago (e.g. Barker et al. 2012). We analyzed five different submarine phonolites that were sampled by remotely operated vehicles (ROV) Kiel 6000 and dredging during the RV Meteor (M80/3) and RV Poseidon (POS320/2) cruises. Fresh sanidine, nepheline, and biotite grains were selected and carefully prepared for 40Ar-39Ar single grain total fusion analysis. Sanidine single grain 40Ar-39Ar ages from 5 samples range from 11.5 ± 6.5 ka to 349.0 ± 20.4 ka (2σ errors), and cluster in several age groupings (using the decay constant and atmospheric air ratio of Steiger & Jäger (1977), and age standard TCS2 (27.87 ± 0.04 Ma; 1σ; M.A. Lanphere, pers. comm.)). Three age groups can be identified within the youngest (0-170 ka) sanidines, which are separated by periods of 52-54 ka. Nepheline grains from one sample yielded much older ages of 169.5 ± 16.5 ka to 1521.5 ± 8.3 ka (2σ). Our data suggests young ages for the Cadamosto Seamount, which is in accordance with recorded seismic activity (Grevemeyer et al. 2010), and its position adjacent to the recently active islands of Fogo (last eruption in 2014/2015) and Brava (recent seismic activity). The different sub-groups of sanidine 40Ar-39Ar ages can be used to identify different activity maxima corresponding to cycles of magmatic productivity in a long-lived magmatic system. Ongoing petrologic investigations will be used to identify the relative importance of processes such as mantle melting rates, magma replenishment and magma chamber processes

  5. Age of the youngest volcanism at Eagle Lake, northeastern California—40Ar/39Ar and paleomagnetic results

    The age of the youngest volcanism at Eagle Lake, California, was investigated using stratigraphic, paleomagnetic, and 40Ar/39Ar techniques. The three youngest volcanic lava flows at Eagle Lake yielded ages of 130.0±5.1, 127.5±3.2 and 123.6±18.7 ka, and are statistically indistinguishable. Paleomagnetic results demonstrate that two of the lava flows are very closely spaced in time, whereas the third is different by centuries to at most a few millennia. These results indicate that the basalt lava flows at Eagle Lake are not Holocene in age, and were erupted during an episode of volcanism at about 130–125 ka that is unlikely to have spanned more than a few thousand years. Thus, the short-term potential for subsequent volcanism at Eagle Lake is considered low.

    To assess pregnancy outcome in women aged > or =35, followed prospectively, and the relation between maternal age and the incidence of abortions after 12 gw (spontaneous and medical), preterm delivery, mode of delivery and congenital anomalies. 495 women from the Fetal Medicine Clinic of the State University Hospital "Maichin Dom" in Sofia were enrolled in the study between 02/2012 and 02/2014 with gestational age > or =12 completed weeks. The patients were devided in 3 groups according to age-- < or =34, between 35 and 39 and > or = 40 years of age. Pregnancy outcome was veirified from hospital records and phone intenrviews with the patients themselves. Data were processed with SPSS 13.0 statistical package. Descriptive and comparative analysis was performed after grouping according to one or more characteristics; p values <0.05 were considered as evidence of statistical significance for tested effects. 131/495 (26.5%) of the patients were < or =34 years of age, 254/495 (51.3%) were between 35 and 39 and 110/495 (22.2%) were > or =40 years of age. Maternal age > or =35 was associated with statistically significant increase of the total late abortion rate (spontaneous and medical abortions)--from 6.9% for those < or =34 yars of age to 11.3%--for the ones between 35-39 and 11.4%--for the ones > or =40 years. There was also statistically significant increase in the incidence of late medical abortions in the group > or =40 years of age (p=0.011). It was 2/124 (1.6%) for the group aged < or =34, 7/230 (3%)--in the group aged 35-39 and 9/100 (9.0%)--in the group > or =40 years of age. The difference in late spontaneous abortions rate was not statistically significant among the groups. There was statistically significant increase in the incidence of preterm deliveries (spontaneous and induced)--14/131 (10.7%) in the group aged < or =34, 52/208 (25.0%)--in the group between 35-39 and 20/93 (21.5%)--in the group > or =40 years of age (p=0.013).

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

    2012-01-01

    Objectives and Method Information about aging-related change in coping is limited mainly to results of cross-sectional studies of age differences in coping, and no research has focused on predictors of aging-related change in coping behavior. To extend research in this area, we used longitudinal multilevel modeling to describe older adults’ (n=719; baseline M=61 years) 20-year, intra-individual approach and avoidance coping trajectories, and to determine the influence of two sets of predictors (threat appraisal and stressor characteristics; gender and baseline personal and social resources) on level and rate of change in these trajectories. Results Over the 20-year study interval participants declined in use of approach coping and most avoidance coping strategies, but there was significant variation in this trend. In simultaneous predictive models, female gender, more threat appraisal, stressor severity, social resources, and depressive symptoms; and fewer financial resources, were independently associated with higher initial levels of coping responses. Having more social resources, and fewer financial resources, at baseline in late-middle-age predicted faster decline over time in approach coping. Having more baseline depressive symptoms, and fewer baseline financial resources, hastened decline in use of avoidance coping. Independent of other variables in these models, decline over time in approach coping and avoidance coping remained statistically significant. Conclusion Overall decline in coping may be a normative pattern of coping change in later life. However, it also is modifiable by older adults’ stressor appraisals, their stressors, and the personal and social resources they possess at entry to later life, in late-middle age. PMID:22394319

    The purpose of this study was to compare values of aerobic performance in the 1-mile run test (1-MRT) using different formulae. Aerobic capacities of 351 male volunteers working for the Turkish National Police within the age range of 20-23 years were evaluated by the 1-MRT and the 20-metre shuttle run (20-MST). VO2max values were estimated by the prediction equations developed by George et al. (1993), Cureton et al. (1995) and Kline et al. (1987) for the 1-MRT and by Leger and Lambert (1982) for the 20-MST. The difference between the results of the different formulae was significant (p = 0.000). The correlation coefficient between the estimated VO2max using Cureton's equation, George's equation, Kline's equation and the 20-MST were 0.691 (p < 0.001), 0.486 (p < 0.001) and 0.608 (p < 0.001), respectively. The highest correlation coefficient was between the VO2max estimated by the 20-MST and Cureton's equation. Similarly, the highest correlation coefficient (r = -0.779) was between the 1-mile run time and the VO2max estimated by Cureton's equation. When analysing more vigorous exercise than sub-maximal exercise, we suggest that Cureton's equation be used to predict the VO2max from 1-mile run/walk performance in large numbers of healthy individuals with high VO2max. This research compares the use of 3 different formulae to estimate VO2max from 1-mile run/walk performance in male law enforcement officers aged 20-23 years for the first time and reports the most accurate formula to use when evaluating aerobic capacities of large numbers of healthy individuals.

    Background Early malnutrition is linked to poor cognition, but long-term effects have not been extensively examined and psychosocial confounds have not always been controlled. Objective To test the hypothesis that malnutrition at age 3 years will be associated with poorer cognitive ability at age 11 years independent of psychosocial confounds. Design A prospective, longitudinal study of a birth cohort of 1559 children originally assessed at age 3 years for malnutrition (low hemoglobin level, angular stomatitis, kwashiorkor, and sparse, thin hair) and followed up to age 11 years. Setting and Participants A community sample of 1559 children (51.4% boys and 48.6% girls) born between September 1, 1969, and August 31, 1970, in 2 towns in the island of Mauritius, with 68.7% Indians and 25.7% Creoles (African origin). Main Outcome Measures Verbal and spatial ability measured at ages 3 and 11 years and reading, scholastic ability, and neuropsychologic performance measured at age 11 years. Results Malnourished children had poorer cognition at both ages. Deficits were stable across time, applied to all sex and ethnic groups, and remained after controlling for multiple measures of psychosocial adversity. Children with 3 indicators of malnutrition had a 15.3-point deficit in IQ at age 11 years. Conclusions Malnutrition at age 3 years is associated with poor cognition at age 11 years independent of psychosocial adversity. Promoting early childhood nutrition could enhance long-term cognitive development and school performance, especially in children with multiple nutritional deficits. PMID:12796242

    2002-11-01

    Three samples of Darwin Glass, an impact glass found in Tasmania, Australia at the edge of the Australasian tektite strewn field were dated using the 40Ar/39Ar single-grain laser fusion technique, yielding isochron ages of 796-815 ka with an overall weighted mean of 816 ± 7 ka. These data are statistically indistinguishable from those recently reported for the Australasian tektites from Southeast Asia and Australia (761-816 ka; with a mean weighted age of 803 ± 3 ka). However, considering the compositional and textural differences and the disparity from the presumed impact crater area for Australasian tektites, Darwin Glass is more likely to have resulted from a distinct impact during the same period of time.

    Cancer for teenagers and young adults represents a major source of morbidity and mortality. Trends in cancer incidence can provide pointers concerning how changes in the environment and in personal behavior affect cancer risks. Data on 39,129 neoplasms in individuals ages 13 to 24 years who were diagnosed in England from 1979 to 2003 were analyzed. Variability in incidence by time period and differences in the time trends by age group, sex, and geographic region were analyzed using generalized linear models. Incidence rates of leukemias, lymphomas, central nervous system, bone, and germ cell tumors; melanoma; and carcinomas of the thyroid, ovary, cervix, and colon/rectum increased over time (all P < .01); whereas the incidence of carcinomas of the stomach and bladder decreased (both P < .01). These changes were consistent by age, sex, and region for most neoplasms. Melanoma incidence stabilized in southern England by 1993 but continued to increase in northern England (P = .001). The increase in non-Hodgkin lymphoma was greater in individuals ages 20 to 24 year than in younger individuals, but the increase in Hodgkin lymphoma was confined to individuals ages 13 to 14 years. The changes in incidence rates may have been caused in part by environmental changes and in part by behavioral changes in young individuals. Some of these results can be used to inform public health campaigns, which can be constructed to encourage better lifestyle choices by young individuals.

    To forecast the number of U.S. individuals aged <20 years with type 1 diabetes mellitus (T1DM) or type 2 diabetes mellitus (T2DM) through 2050, accounting for changing demography and diabetes incidence. We used Markov modeling framework to generate yearly forecasts of the number of individuals in each of three states (diabetes, no diabetes, and death). We used 2001 prevalence and 2002 incidence of T1DM and T2DM from the SEARCH for Diabetes in Youth study and U.S. Census Bureau population demographic projections. Two scenarios were considered for T1DM and T2DM incidence: 1) constant incidence over time; 2) for T1DM yearly percentage increases of 3.5, 2.2, 1.8, and 2.1% by age-groups 0-4 years, 5-9 years, 10-14 years, and 15-19 years, respectively, and for T2DM a yearly 2.3% increase across all ages. Under scenario 1, the projected number of youth with T1DM rises from 166,018 to 203,382 and with T2DM from 20,203 to 30,111, respectively, in 2010 and 2050. Under scenario 2, the number of youth with T1DM nearly triples from 179,388 in 2010 to 587,488 in 2050 (prevalence 2.13/1,000 and 5.20/1,000 [+144% increase]), with the greatest increase in youth of minority racial/ethnic groups. The number of youth with T2DM almost quadruples from 22,820 in 2010 to 84,131 in 2050; prevalence increases from 0.27/1,000 to 0.75/1,000 (+178% increase). A linear increase in diabetes incidence could result in a substantial increase in the number of youth with T1DM and T2DM over the next 40 years, especially those of minority race/ethnicity.

    In the past two decades, pancreas surgery (PS) has undergone significant advances in operative techniques and with a focus on multidisciplinary high-volume practices. A review of patients undergoing PS from 3/1995-2/2015 was conducted; dividing patients into group A (1995-2005) and group B (2005-2015) for a detailed comparison. Effect of surgeon volume in group B was determined. A total of 1001 patients underwent PS (group A: 259; group B: 742). The mean age was 62.7 years and 52.8% were female. Group B patients were associated with a higher rate of pylorus preservation and minimally invasive resection and a lower rate of morbidity, pancreas fistula (PF), and delayed gastric emptying (DGE) than group A. High-volume surgeons (HVS) had lower operative blood loss (300 mL vs 600 mL), transfusion requirements, PF (14% vs 20%), DGE, surgical site infections, reoperations, and major morbidity rate (15.5 vs 39%) than low-volume surgeons. This study demonstrates improved patient outcomes and hospital resource utilization over the past 20 years. Concentration of PS to HVS results in superior results. Copyright © 2017 Elsevier Inc.

    Context For the last 50 years, overall age-standardized incidence rates for noncardia gastric cancer have steadily declined in most populations. However, overall rates are summary measures that may obscure important age-specific trends. Objective To examine effects of age at diagnosis on noncardia gastric cancer incidence trends in the United States. Design, Setting, and Participants Descriptive study with age-period-cohort analysis of cancer registration data from the National Cancer Institute's Surveillance, Epidemiology, and End Results Program, which covers approximately 26% of the US population. From 1977 through 2006, there were 83 225 adults with incident primary gastric cancer, including 39 003 noncardia cases. Main Outcome Measures Overall and age-specific incidence rates, adjusted for period and cohort effects using age-period-cohort models. Results were stratified by race, sex, and socioeconomic status. Results Overall age-standardized annual incidence per 100 000 population declined during the study period from 5.9 (95% confidence interval [CI], 5.7-6.1) to 4.0 (95% CI, 3.9-4.1) in whites, from 13.7 (95% CI, 12.5-14.9) to 9.5 (95% CI, 9.1-10.0) in blacks, and from 17.8 (95% CI, 16.1-19.4) to 11.7 (95% CI, 11.2-12.1) in other races. Age-specific trends among whites varied significantly between older and younger age groups (P < .001 for interaction by age): incidence per 100 000 declined significantly from 19.8 (95% CI, 19.0-20.6) to 12.8 (95% CI, 12.5-13.1) for ages 60 to 84 years and from 2.6 (95% CI, 2.4-2.8) to 2.0 (95% CI, 1.9-2.1) for ages 40 to 59 years but increased significantly from 0.27 (95% CI, 0.19-0.35) to 0.45 (95% CI, 0.39-0.50) for ages 25 to 39 years. Conversely, rates for all age groups declined or were stable among blacks and other races. Age-period-cohort analysis confirmed a significant increase in whites among younger cohorts born since 1952 (P < .001). Conclusions From 1977 through 2006, the incidence rate for noncardia gastric

    Studies of biologic age formation and ageing rate in workers of mechanic workshops revealed that able-bodied population grew old demographically. That is proved by absent age group of 20-29 years and increased share of able-bodied workers older than 50. Young workers aged 30-39 appeared the most vulnerable for occupational hazards--they demonstrated increased ageing rate and maximal excess of biologic age over chronological age and due biologic age.

    Tens of millions of seniors are at risk of herpes zoster (HZ) and its complications. Live attenuated herpes zoster vaccine (HZV) reduces that risk, although questions regarding effectiveness and durability of protection in routine clinical practice remain. We used Medicare data to investigate HZV effectiveness (VE) and its durability. This retrospective cohort study included beneficiaries ages ≥65 years during January 2007 through July 2014. Multiple adjustments to account for potential bias were made. HZV-vaccinated beneficiaries were matched to unvaccinated beneficiaries (primary analysis) and to HZV-unvaccinated beneficiaries who had received pneumococcal vaccination (secondary analysis). HZ outcomes in community and hospital settings were analyzed, including ophthalmic zoster (OZ) and postherpetic neuralgia (PHN). Among eligible beneficiaries (average age 77 years), the primary analysis found VE for community HZ of 33% (95% CI: 32%-35%) and 19% (95% CI: 17%-22%), for the first 3, and subsequent 4+ years postvaccination, respectively. In the secondary analysis, VE was, respectively, 37% (95% CI: 36%-39%) and 22% (95% CI: 20%-25%). In the primary analysis, VE for PHN was 57% (95% CI: 52%-61%) and 45% (95% CI: 36%-53%) in the first 3 and subsequent 4+ years, respectively; VE for hospitalized HZ was, respectively, 74% (95% CI: 67%-79%) and 55% (95% CI: 39%-67%). Differences in VE by age group were not significant. In both the primary and secondary analyses, HZV provided protection against HZ across all ages, but effectiveness declined over time. VE was higher and better preserved over time for PHN and HZ-associated hospitalizations than for community HZ.

    Abundant fossils of the terrestrial Jehol Biota, including plants, insects, dinosaurs, birds, mammals and freshwater invertebrates, were discovered from the Yixian Formation and the overlying Jiufotang Formation in Inner Mongolia, Hebei Province and Liaoning Province, northeastern China. Because of the exceptional preservation of fossils, the Jehol Biota is one of the most important Mesozoic fossil outcrops and referred to as a "Mesozoic Pompeii". The Jehol Biota has provided a rare opportunity to address questions about the origin of birds, the evolution of feathers and flight, the early diversification of angiosperms and the timing of the radiation of placental mammals. The Tuchengzi Formation, which lies unconformably just below the Yixian Formation and consists mainly of variegated sandstones, is less fossiliferous than the two overlying formations. However, dinosaur tracks, silicified wood and compressed plants are found in this formation. A systematic 40Ar/39Ar dating of the Yixian and the Jiufotang formations was undertaken to provide a framework for understanding the timing and duration of the Jehol Biota and evolutionary events represented within it. Furthermore, determining the absolute age of the Tuchengzi Formation provides information to interpret abundant dinosaur tracks within and provide better age constrains for the beginning of the Jehol Biota. Here we present robust high-precision 40Ar/39Ar data for six tuff samples and two basalt samples collected from the Tuchengzi, the Yixian and the Jiufotang formations near the classic outcrops in western Liaoning, NE China. We obtain an age of 139.5 ± 1.0 Ma for the uppermost Tuchengzi Formation, an age of 129.7 ± 0.5 Ma for a basaltic lava from the bottom of the Yixian Formation and an age of 122.1 ± 0.3 Ma for a tuff from the base of the overlying Jiufotang Formation. Our data indicate that the Yixian Formation was deposited during the Early Cretaceous, the Barremian to early Aptian, within a time span

    The contemporaneous Rotoiti and Earthquake Flat ignimbrites, erupted from the Taupo Volcanic zone, New Zealand, form a distinctive tephrostratigraphic horizon in the Southern Pacific. Radioisotopic dating results for these eruptions remain controversial, with published ages ranging from 35.1 × 2.8 ka [1] to 71 × 6 ka [2], with 61.0 × 1.5 ka [3] often being cited as the most widely accepted age. These eruptions are difficult to date as their age is near the limit for various radiometric dating techniques, which are complicated by a large proportion of inherited material (xenocrysts) and a lack of phases suitable for dating. Glass-bearing plutonic blocks erupted with the Rotoiti and Earthquake Flat ignimbrites have previously been interpreted as deriving from a slowly cooled and incompletely solidified magma body that was sampled by the eruptions. They contain large vugs lined with euhedral quartz, sanidine and biotite crystals, indicating that these crystals grew in a gas or aqueous fluid rich environment and are interpreted to have formed shortly before or during eruption. Here we will present Ar-40/Ar-39 ages for sanidines and biotites extracted from vugs in lithic blocks erupted as part of the Earthquake Flat ignimbrite. We show that, even for vug-lining material, inherited ages remain a problem and are the likely source of the wide variation in published radiometric ages. Nevertheless, many of the Ar-40/Ar-39 ages are much younger than the 61 ka age [3] and are more consistent with the recent stratigraphic, C-14 and U-238/Th-230+(U-Th)/He ages that have been suggested (e.g. [4,5]). 1.

    Early administration of reperfusion therapy in acute ST-elevation myocardial infarctions (STEMI) is crucial to reduce mortality. Although female sex and old age are key factors contributing to an inadequate long prehospital delay time, little is known whether women ≥65 years are a particular risk population. Hence, we studied the interaction of sex and age (<65 years or ≥65 years) and the contribution of chest pain to delay time during STEMI. Bedside interview data were collected in 619 STEMI patients from the Munich Examination of Delay in Patients Experiencing Acute Myocardial Infarction (MEDEA) study. Sex and age group stratification disclosed an excess delay risk for women ≥65 years, accounting for a 2.39 (95% confidence interval (CI) 1.39 to 4.10)-fold higher odds to delay longer than 2 hours compared with all other patient groups including younger women (p ≤0.002). Median delay time was 266 minutes in women ≥65 years and 148 minutes in younger women (p <0.001). Chest pain during STEMI had the lowest frequency both in women (81%) and men ≥65 years (83%) and the highest frequency (95%) in younger women. Experiencing non-chest pain was 2.32-fold (95% CI, 1.20 to 4.46, p <0.05) higher in women ≥65 years than in all other patients. Mediation analysis disclosed that the effect accounted for only 9% of the variance. Age specific educational strategies targeting women ≥65 years at risk are urgently needed. To tailor adequate strategies, more research is required to understand age- and sex driven barriers to timely identification of ischemic symptoms. Copyright © 2017 Elsevier Inc. All rights reserved.

    Cleft lip and palate is a common congenital malformation with a prevalence of 1:600 newborns. Children with orofacial clefts are treated by an interdisciplinary team of specialists while parents and child play a key role in their own care process. The orthodontic and facial orthopedic treatment of a child with a cleft takes many years. Children often get bored of the long treatment and this can cause problems with compliance and oral hygiene. Therefore it is advisable to distinguish 5 well-defined stages in the orthodontic treatment and to attempt to have some 'orthodontics free' time in between. The 3 orthodontic treatment phases between the age of 9 and 20 years consist of orthodontic treatment concerning the closing of the cleft with a bone transplant, the treatment of the permanent dentition and, finally, a possible combined orthodontic surgical treatment at the end of the period of growth. Good interdisciplinary collaboration among the different dental disciplines is essential in this regard.

    In 2015, persons aged 10-24 years who were treated for nonfatal assault injuries in emergency departments (EDs) in the United States accounted for 32% of the approximately 1.5 million patients of all ages that EDs treated for nonfatal assault injuries (1). CDC analyzed data from the National Electronic Injury Surveillance System-All Injury Program (NEISS-AIP) to examine 2001-2015 trends in nonfatal assault injuries among youths treated in EDs, by sex and age group, and to assess current rates by sex, age group, mechanism of injury, and disposition (1). Rates for 2001-2015 were significantly higher among males than among females and among young adults aged 20-24 years than among youths aged 10-14 and 15-19 years. During 2011-2015, rates declined for all groups. The 2015 rate among persons aged 10-24 years was 753.2 per 100,000 population, the lowest in the 15-year study period. Despite encouraging trends, the assault rate among young persons remains high. Rates in 2015 were higher among males, persons aged 20-24 years, and those who incurred intentional strike or hit injuries. Nearly one in 10 patients were admitted to the hospital, transferred to another hospital, or held for observation. Youth violence prevention strategies, including primary prevention approaches that build individual skills, strengthen family relationships, or connect young persons treated in EDs to immediate and ongoing support, can be implemented to decrease injuries and fatalities (2).

    40Ar/39Ar ages on the Hat Creek Basalt (HCB) and stratigraphically related lava flows show that latest Pleistocene tholeiitic basalt with very low K2O can be dated reliably. The HCB underlies ∼ 15 ka glacial gravel and overlies four andesite and basaltic andesite lava flows that yield 40Ar/39Ar ages of 38 ± 7 ka (Cinder Butte; 1.65% K2O), 46 ± 7 ka (Sugarloaf Peak; 1.85% K2O), 67 ± 4 ka (Little Potato Butte; 1.42% K2O) and 77 ± 11 ka (Potato Butte; 1.62% K2O). Given these firm age brackets, we then dated the HCB directly. One sample (0.19% K2O) clearly failed the criteria for plateau-age interpretation, but the inverse isochron age of 26 ± 6 ka is seductively appealing. A second sample (0.17% K2O) yielded concordant plateau, integrated (total fusion), and inverse isochron ages of 26 ± 18, 30 ± 20 and 24 ± 6 ka, all within the time bracket determined by stratigraphic relations; the inverse isochron age of 24 ± 6 ka is preferred. As with all isotopically determined ages, confidence in the results is significantly enhanced when additional constraints imposed by other isotopic ages within a stratigraphic context are taken into account.

    There is paucity of studies examining suicide rates in narrow five-year age-bands after the age of 60 years. This study examined suicide rates in eight five-year age-bands between the age of 60 and 99 years because this will allow more precise comparison between the young old (60-79 years) and the oldest old (80+ years) age groups. Data on the number of suicides (International Classification of Diseases - ICD-10 codes, X60-84) in each of the eight five-year age-bands between the age-bands 60-64 years and 95-99 years in both gender for as many years as possible from 2000 were ascertained from three sources: colleagues with access to national data, national statisics office websites and email contact with the national statistics offices. The population size for the corresponding years and age-bands was estimated for each country using data provided by the United Nations website. In men, suicide rates continued to increase for each of the seven five-year age-bands from 60-64 years to 90-94 years age-band, and then declined slightly for the 95-99 year age-band. In women, suicide rates continued to increase for each of the six five-year age-bands from 60-64 years to 85-89 years age-bands, and then declined slightly for the 90-94 years and 95-99 years age-bands. The overall global suicide rates for each of the eight five-year age-bands are sufficiently large for them to constitute a public health concern. This is especially important given the ongoing rise in the elderly population size and the paucity of data on risk and protective factors for suicide in the five-year age-bands after the age of 60 years.

Four of the six samples gave reproducible age spectra with well-defined intermediate temperature plateaus over 48% or more of the {sup 39}AR released; the plateaus are interpreted as crystallization ages. Samples 15304,7,69, 15294,6,21, and 15314,26,156 gave virtually identical plateau ages whose weighted mean is 3,870 {plus minus} 6 Ma.

    40Ar 39Ar ages of volcanic rocks are used to provide numerical constraints on the age of middle and upper Miocene sedimentary strata collected along the Porcupine River. Intercalated sedimentary rocks north of latitude 67??10???N in the Porcupine terrane of east-central Alaska contain a rich record of plant fossils. The fossils are valuable indicators of this interior region's paleoclimate during the time of their deposition. Integration of the 40Ar 39Ar results with paleomagnetic and sedimentological data allows for refinements in estimating the timing of deposition and duration of selected sedimentary intervals. 40Ar 39Ar plateau age spectra, from whole rock basalt samples, collected along the Upper Ramparts and near Half-way Pillar on the Porcupine River, range from 15.7 ?? 0.1 Ma at site 90-6 to 14.4 ?? 0.1 Ma at site 90-2. With exception of the youngest basalt flow at site 90-2, all of the samples are of reversed magnetic polarity, and all 40Ar 39Ar age spectrum results are consistent with the deposition of the entire stratigraphic section during a single interval of reversed magnetic polarity. The youngest flow at site 90-2 was emplaced during an interval of normal polarity. With age, paleomagnetic and sedimentological data, the ages of the Middle Miocene sedimentary rocks between the basalt flows at sites 90-1 and 90-2 can be assigned to an interval within the limits of analytical precision of 15.2 ?? 0.1 Ma; thus, the sediments were deposited during the peak of the Middle Miocene thermal maximum. Sediments in the upper parts of sites 90-1 and 90-2 were probably deposited during cooling from the Middle Miocene thermal maximum. 40Ar 39Ar results of plagioclase and biotite from a single tephra, collected at sites 90-7 and 90-8 along the Canyon Village section of the Porcupine River, indicate an age of 6.57 ?? 0.02 Ma for its time of eruption and deposition. These results, together with sedimentological and paleomagnetic data, suggest that all of the Upper

    Background Leptospirosis is an emerging but neglected public health challenge in the Asia/Pacific Region with an annual incidence estimated at 10–100 per 100,000 population. No accurate data, however, are available for at-risk rural Cambodian communities. Method We conducted anonymous, unlinked testing for IgM antibodies to Leptospira spp. on paired sera of Cambodian patients <20 years of age between 2007–2009 collected through active, community-based surveillance for febrile illnesses in a convenience sample of 27 rural and semi-rural villages in four districts of Kampong Cham province, Cambodia. Leptospirosis testing was done on paired serological samples negative for Dengue, Japanese encephalitis and Chikungunya viruses after random selection. Convalescent samples found positive while initial samples were negative were considered as proof of acute infection. We then applied a mathematical model to estimate the risk of fever caused by leptospirosis, dengue or other causes in rural Cambodia. Results A total of 630 samples are coming from a randomly selected subset of 2358 samples. IgM positive were found on the convalescent serum sample, among which 100 (15.8%) samples were IgM negative on an earlier sample. Seventeen of these 100 seroconversions were confirmed using a Microagglutination Test. We estimated the probability of having a fever due to leptospirosis at 1. 03% (95% Credible Interval CI: 0. 95%–1. 22%) per semester. In comparison, this probability was 2. 61% (95% CI: 2. 55%, 2. 83%) for dengue and 17. 65% (95% CI: 17. 49%, 18. 08%) for other causes. Conclusion Our data from febrile cases aged below 20 years suggest that the burden of leptospirosis is high in rural Cambodian communities. This is especially true during the rainy season, even in the absence of identified epidemics. PMID:27043016

    The response of CR-39 nuclear track detector (TasTrak®) to protons in the energy range of 0.92-9.28 MeV has been studied. Previous studies of the CR-39 response to protons have been extended by examining the piece-to-piece variability in addition to the effects of etch time and etchant temperature; it is shown that the shape of the CR-39 response curve to protons can vary from piece-to-piece. The effects due to the age of CR-39 have also been studied using 5.5 MeV alpha particles over a 5-year period. Track diameters were found to degrade with the age of the CR-39 itself rather thanmore » the age of the tracks, consistent with previous studies utilizing different CR-39 over shorter time periods.« less

    Neisseria meningitidis invasive disease is a major public health problem. Pharyngeal carriage is considered a prerequisite for invasive infection. Prevalence reaches 10% in general population and up to 30% in the 20-24 years age group. The aim of this study was to asses pharyngeal carriage prevalence in healthy subjects aged 18-24 years, and as secondary endpoints evaluate known risk factors, to identify serogroups and sequence in the isolated strains. Cross-sectional study in 500 healthy subjects; students from Universidad de Chile aged 18-24 years, Santiago, Chile, October 2012. Each subject underwent a risk factor survey prior to throat culture sampling. Samples were processed in one central Microbiology Laboratory of Hospital Luis Calvo Mackenna and serogrouping and sequencing was performed at Instituto de Salud Pública de Chile. We obtained throat samples from 500 healthy subjects, 20 (4%) positive for N. meningitidis. Of positive strains 20% were serogroup B, 15% W and the rest non groupable. The median age was 20 years, 50% were men. Of the risk factors evaluated, 24% were current smokers, 16% shared a room, 72% had kissed someone during the last month, 64% had gone to pub and 76% had consumed alcohol in the same period of time. Literatures meningococcal carriage prevalence reaches up to 30% in people aged 18-24 years. Prevalence in our study was 4%. Different interpretations could be given; one could be the absence of overcrowding in our students because of the lack of dorms in our scholar system and also the characteristics of our enrolled group. Our results suggest the necessity to extend the study to other age groups and to other cities, to better understand the Chilean reality, as well as others regions of America, considering that these results cannot be extrapolated to another countries.

  19. 20 years of trauma documentation in Germany--actual trends and developments.

    PubMed

    2014-10-01

    The TraumaRegister DGU(®) has been founded 20 years ago. Although initially supported by larger hospitals and universities, it has recently become a representative registry for the care of severely injured patients in Germany. Based on the registry data some important trends and developments of the recent decades are presented. German trauma patients with an Injury Severity Score (ISS)≥ 16 were eligible if primary admitted from the scene. All cases documented between 1993 and 2012 (20 years) were eligible. For selected variables, an average change per years was calculated using linear regression analysis. A total of 49,801 patients was analysed. The mean age was 46.3 years, and 72% were males. The following relevant trends could be observed: The average age increased dramatically from 38 to 50 years. Pre-hospital intubation rate was halfed in patients with Glasgow Coma Scale (GCS)>8 but remained constant in unconscious patients (GCS ≤ 8; 90% intubation rate). Pre-hospital volume administration decreased as well, which led to less blood transfusions (from 45% to 16%). The use of helicopters for transportation into a trauma centre decreased as well but today still 27% of all cases are transported by air. Whole-body CT was performed in about 80% of patients; this value is stable in the last four years. Hospital mortality could be reduced and was 2-3% lower than expected in recent years. The Revised Injury Severity Classification (RISC) score used as a reference here was based on TR-DGU data from the 1990s. Standardised prospective registration of severely injured patients over 20years allows to empirically monitor trends and developments in acute trauma care. Copyright © 2014 Elsevier Ltd.

    Both type 1 and type 2 diabetes are considered to be associated with different degrees of progressive beta cell damage. However, few long-term studies have been made. Our aim was to study the clinical course of 20 years of diabetes disease, including diabetes progression, comorbidity, and mortality in a prospectively studied cohort of consecutively diagnosed diabetic patients. Among all 233 patients diagnosed with diabetes during 1985-1987 in Malmö, Sweden, 50 of 118 surviving patients were followed-up after 20 years. The age at diagnose was 42.3 ± 23.1 and 57.5 ± 13.6 years for antibody-positive and antibody-negative patients, respectively. HbA1c and plasma lipids were analyzed with regard to metabolic control. Islet antibody-negative patients at diagnosis had highly preserved C-peptide levels after 20 years in contrast to antibody-positive patients (antibody negative: C-peptide 0 years 0.78 ± 0.47 and 20 years 0.70 ± 0.46 (nmol/l), P = 0.51 and antibody positive: C-peptide 0 years 0.33 ± 0.35 and 20 years 0.10 ± 0.18; P < 0.001. Islet antibodies but not age, BMI, or C-peptide at diagnosis were predictors of C-peptide levels at 20 years when analyzed by logistic regression (P < 0.05). HbA1c did not differ between the groups after 20 years. The 20-year mortality was higher among antibody-negative patients, dependent on the higher age at diagnosis in this group (number of deaths: antibody positive: 18 of 56 vs. antibody negative: 109 of 188, P < 0.001). Of the deceased, 79% had died from diseases or complications that may be associated with diabetes. We found no progressive beta cell damage in autoantibody-negative diabetes at a 20-year follow-up of the clinical course of diabetes.

    AIM: The study aimed to analyse differences in colourimetric parameters L*a*b*, depended on age. MATERIAL AND METHODS: In this study were included 255 subjects with age interval from 20 to 49 years. The subjects were divided into three groups, as follows: in the younger group were 20 to 29 years of age, those in the middle group 30 to 39 years and older group 40 to 49 years. The overall number of analysed teeth in the intercanine sector of the maxilla was 2295. The colour of the teeth was measured using the spectrophotometer VITA Easyshade. RESULTS: The results for differences in the colourimetric parameters in relation with age were tested with Pearson Chi-square (χ2). For χ2 = 572, 87 and df = 124 there was a statistical significant difference between the ages P < 0.001. CONCLUSION: In this study, it was concluded that the parameter L* - Lightness was decreasing when age increased. In the age group, 20 to 29 years L* was 83.2, whereas in the older group of this investigation; 40 to 49 years was 79.4. In the youngest group, the parameter a* was - 0.7, whereas with increasing of age this parameter was -0.5. The values for parameter b* from the youngest to the older group were from 21.7 to 23.9.

    Radiometric dating of martian nakhlites by several techniques have given similar ages of approx.1.2-1.4 Ga [e.g. 1, 2]. Unlike the case with shergottites, where the presence of martian atmosphere and inherited radiogenic Ar-40 produce apparent Ar-39-Ar-40 ages older than other radiometric ages, Ar-Ar ages of nakhlites are similar to ages derived by other techniques. However, even in some nakhlites the presence of trapped martian Ar produces some uncertainty in the Ar-Ar age. We present here an analysis of such Ar-Ar ages from the MIL03346 and Y000593 nakhlites.

    We assessed the incidence of infants born small-for-gestational-age (SGA) and large-for-gestational-age (LGA) in an Italian cohort over 20 years (1993-2013). Furthermore, we investigated maternal factors associated with SGA and LGA births. A retrospective review of obstetric records was performed on infants born in Chieti (Italy) covering every 5(th) year over a 20-year period, specifically examining data for 1993, 1998, 2003, 2008, and 2013. Infants with birthweight <10(th) percentile were defined as SGA, and those with birthweight >90(th) percentile as LGA. Data collected included newborn anthropometry, birth (multiple vs singleton), maternal anthropometry, previous miscarriage, gestational diabetes, hypertension, and smoking during pregnancy. There were a pooled total of 5896 live births recorded across the 5 selected years. The number of SGA (+60.6 %) and LGA (+90.2 %) births increased considerably between 1993 and 2013. However, there were no marked changes in the incidence of SGA or LGA births (8.3 % and 10.8 % in 1993 versus 7.6 % and 11.7 % in 2013, respectively). Maternal factors associated with increased risk of SGA infants included hypertension, smoking, and previous miscarriage (all p < 0.05), while greater pre-pregnancy BMI and gestational diabetes were risk factors for LGA births (all p < 0.05). There was an increase in the number of SGA and LGA births in Chieti over the last two decades, but there was little change in incidence over time. Most maternal factors associated with increased odds of SGA and LGA births were modifiable, thus incidence could be reduced by targeted interventions.

    To examine how corneal astigmatism changes with age over 20 years after cataract surgery and to assess whether the changes differ from those in eyes that did not have surgery. Hayashi Eye Hospital, Fukuoka, Japan. Retrospective case study. Using an autokeratometer, corneal astigmatism was measured preoperatively, at baseline (the day the surgically induced astigmatism stabilized), and 10 years and 20 years after baseline. The change in corneal astigmatism between baseline and 10 years, 10 years and 20 years, and baseline and 20 years was determined using power vector analysis and compared between the time intervals and between groups. The study assessed 74 eyes that had phacoemulsification with a horizontal scleral incision more than 21 years ago (surgery group) and 68 eyes that did not have surgery (no-surgery group). The mean vertical/horizontal change in corneal astigmatism (J0) between baseline and 20 years was -0.64 diopter (D) in the surgery group and -0.49 D in the no-surgery group. The oblique change (J45) was -0.03 D in the surgery group and 0.07 D in the no-surgery group. Using multivariate comparison, the mean J0 and J45 values were not significantly different between baseline and 10 years or between 10 years and 20 years in both groups (P ≥ .2350). The J0 and J45 values were not significantly different between the 2 groups at any time interval (P ≥ .1331). Corneal astigmatism continues to change toward against-the-rule astigmatism over 20 years after cataract surgery. This change was similar in eyes that did not have surgery.

    To determine the visual acuity outcome at age 10 years for children younger than 7 years when enrolled in a treatment trial for moderate amblyopia. In a multicenter clinical trial, 419 children with amblyopia (visual acuity, 20/40-20/100) were randomized to patching or atropine eyedrops for 6 months. Two years after enrollment, a subgroup of 188 children entered long-term follow-up. Treatment after 6 months was at the discretion of the investigator; 89% of children were treated. Visual acuity at age 10 years with the electronic Early Treatment Diabetic Retinopathy Study test. Patching and atropine eyedrops produce comparable improvement in visual acuity that is maintained through age 10 years. The mean amblyopic eye acuity, measured in 169 patients, at age 10 years was 0.17 logMAR (logarithm of the minimum angle of resolution) (approximately 20/32), and 46% of amblyopic eyes had an acuity of 20/25 or better. Age younger than 5 years at entry into the randomized trial was associated with a better visual acuity outcome (P < .001). Mean amblyopic and sound eye visual acuities at age 10 years were similar in the original treatment groups (P = .56 and P = .80, respectively). At age 10 years, the improvement of the amblyopic eye is maintained, although residual amblyopia is common after treatment initiated at age 3 years to younger than 7 years. The outcome is similar regardless of initial treatment with atropine or patching.

    The risk of antepartum stillbirth at term is higher among women 35 years of age or older than among younger women. Labor induction may reduce the risk of stillbirth, but it also may increase the risk of cesarean delivery, which already is common in this older age group. We conducted a randomized, controlled trial involving primigravid women who were 35 years of age or older. Women were randomly assigned to labor induction between 39 weeks 0 days and 39 weeks 6 days of gestation or to expectant management (i.e., waiting until the spontaneous onset of labor or until the development of a medical problem that mandated induction). The primary outcome was cesarean delivery. The trial was not designed or powered to assess the effects of labor induction on stillbirth. A total of 619 women underwent randomization. In an intention-to-treat analysis, there were no significant between-group differences in the percentage of women who underwent a cesarean section (98 of 304 women in the induction group [32%] and 103 of 314 women in the expectant-management group [33%]; relative risk, 0.99; 95% confidence interval [CI], 0.87 to 1.14) or in the percentage of women who had a vaginal delivery with the use of forceps or vacuum (115 of 304 women [38%] and 104 of 314 women [33%], respectively; relative risk, 1.30; 95% CI, 0.96 to 1.77). There were no maternal or infant deaths and no significant between-group differences in the women's experience of childbirth or in the frequency of adverse maternal or neonatal outcomes. Among women of advanced maternal age, induction of labor at 39 weeks of gestation, as compared with expectant management, had no significant effect on the rate of cesarean section and no adverse short-term effects on maternal or neonatal outcomes.

  12. Ar-39-Ar-40 Age Dating Of Two Angrites and Two Brachinites

    Garrison, Daniel; Bogard, Donald

    2003-01-01

    Angrites are a rare group (approximately 7 known) of igneous meteorites with basalt-like composition, which probably derive from a relatively small parent body that differs from those of other igneous meteorites. Angrites show evidence for extinct Mn-53, Sm-146, and Pu-244, and precise U-Pb, and Pb-Pb ages of 4.558 Gyr for two angrites define the time of early parent body differentiation. The Sm-147-Nd-143 ages of two angrites range between 4.53 +/- 0.04 and 4.56 +/- 0.04 Gyr, but no Ar-39-Ar-40 or Rb-Sr ages have been reported. Most angrites show no evidence for either shock brecciation or metamorphism. Brachinites are another very rare group' of differentiated meteorites consisting primarily of olivine, with minor augite, chromite, Fe-sulfides, and sometimes plagioclase and opx. Presence of excess Xe-129 and excess Cr53 from decay of Mn-53 in some brachinites indicate that they also formed very early. Brachinite petrogenesis is poorly defined. They may be igneous cumulates or metamorphic products of chondritic-like starting material. If after their formation, angrites and brachinites cooled quickly with minimal subsequent heating, then one might expect them to show uniquely old K-Ar ages, at least in comparison to other differentiated meteorites such as eucrites and mesosiderites. Most angrites and brachinites contain very little, if any K-feldspar, which has deterred measurements of their Ar-Ar ages. We made Ar-39-Ar-40 analyses on two angrites, LEW86010 (metamorphosed) and D'Orbigny, and on two brachinites, EET99402 and Brachina. All are finds. Any feldspar in angrites is highly calcic, with expected K concentrations of <100 ppm. We selected LEW86010 and D'Orbigny because they have been the objects of several other studies and because chemical analyses suggested [K] was approximately 70 ppm in both meteorites. Brachina contains approximately 9.9% plagioclase of higher K-content than angrites, and EET99402 is estimated to contain approximately 5% K

    This study aimed at examining a possible association between cannabis use in adolescence and future disability pension (DP). DP can be granted to any person in Sweden aged 16-65 years if working capacity is judged to be permanently reduced due to long-standing illness or injury. Data were obtained from a longitudinal cohort study comprising 49,321 Swedish men born in 1949-1951 who were conscripted to compulsory military service aged 18-20 years. Data on DP was collected from national registers. Results showed that individuals who used cannabis in adolescence had considerably higher rates of disability pension throughout the follow-up until 59 years of age. In Cox proportional-hazards regression analyses, adjustment for covariates (social background, mental health, physical fitness, risky alcohol use, tobacco smoking and illicit drug use) attenuated the associations. However, when all covariates where entered simultaneously, about a 30% increased hazard ratio of DP from 40 to 59 years of age still remained in the group reporting cannabis use more than 50 times. This study shows that heavy cannabis use in late adolescence was associated with an increased relative risk of labor market exclusion through disability pension. Copyright © 2014 The Authors.

    Background/Objectives The association between weight change and cognition is controversial. We examined the association between 20-year weight change and cognitive function in late life. Design Cohort study. Setting Study of Osteoporotic Fractures (SOF). Participants 1,289 older, community-dwelling women (mean baseline age 68 [65–81] and 88 [82–102] at cognitive testing). Measurements SOF participants had body weight measured repeatedly over 20 years (mean 8 weights). Adjudicated cognitive status was classified as normal (n=775) or mild cognitive impairment (MCI)/dementia (n=514) at Year 20. Logistic models were used to evaluate whether absolute weight change, rate of weight loss per year, presence of abrupt, unrecovered weight loss, and weight variability were associated with MCI or dementia. Results Women with greater rate of weight loss over 20 years had increased chance of developing MCI or dementia. In age/education/clinic-adjusted “base” models, each 0.5 kg/year decrease resulted in 30% increased odds of MCI/dementia (OR=1.30 [95% CI: 1.14, 1.49]). After adjustment for age, education, clinic, depression, and walking speed, there was 17% (OR=1.17 [95% CI: 1.02, 1.35]) increased odds of MCI/dementia for each 0.5 kg/year decrease in weight. In base models, variability in weight was significant. Each 1% average deviation from each woman’s predicted weight curve was associated with 11% increased odds of MCI/dementia (OR=1.11 [95% CI: 1.04, 1.18]). The estimate was attenuated after full adjustment (OR=1.06 [95% CI: 0.99, 1.14]). The presence of an abrupt weight decline was not associated with MCI/dementia. Conclusions Rate of weight loss over 20 years was associated with development of MCI or dementia in women surviving past 80 years, suggesting that nutritional status, social-environmental factors, and/or adipose tissue function and structure may affect cognitive function with aging.

    An ophiolite, considered to be an allochthonous fragment of Tethyan oceanic crust and mantle, crops out near Neyriz in the Zagros Range, Iran. 40Ar 39Ar ages ranging from 76.8 ?? 23.8 Ma to 105 ?? 23.3 Ma were measured on hornblende from five samples of plagiogranite and diabase from the ophiolite. The most precise ages are 85.9 ?? 3.8 Ma for a diabase and 83.6 ?? 8.4 Ma for a plagiogranite. The weighted mean age of hornblende from the five samples is 87.5 ?? 7.2 Ma which indicates that the igneous part of the Neyriz ophiolite formed during the early part of the Late Cretaceous. Pargasite from amphibolite below peridotite of the Neyriz ophiolite has a 40Ar 39Ar age of 94.9 ?? 7.6 Ma. The pargasite age agrees within analytical uncertainty with the ages measured on diabase and plagiogranite. Comparable ages have been measured on igneous rocks from the Samail ophiolite of Oman and on amphibolite below peridotite of the Samail ophiolite. ?? 1983.

    Falls among older adults is one of the major public health challenges facing the rapidly changing demography. The valid assessment of reaction time (RT) and other well-documented risk factors for falls are mainly restricted to specialized clinics due to the equipment needed. The Nintendo Wii Balance Board has the potential to be a multi-modal test and intervention instrument for these risk factors, however, reference data are lacking. To provide RT reference data and to characterize the age-related changes in RT measured by the Nintendo Wii Balance Board. Healthy participants were recruited at various locations and their RT in hands and feet were tested by six assessors using the Nintendo Wii Balance Board. Reference data were analysed and presented in age-groups, while the age-related change in RT was tested and characterized with linear regression models. 354 participants between 20 and 99 years of age were tested. For both hands and feet, mean RT and its variation increased with age. There was a statistically significant non-linear increase in RT with age. The averaged difference between male and female was significant, with males being faster than females for both hands and feet. The averaged difference between dominant and non-dominant side was non-significant. This study reported reference data with percentiles for a new promising method for reliably testing RT. The RT data were consistent with previously known effects of age and gender on RT.

    To compare the characteristics of children with encopresis referred to a single encopresis clinic over the course of 20 years, including symptoms, previous diagnostic and therapeutic interventions, and parental attitudes. A retrospective study was conducted of an encopresis clinic at a tertiary care pediatric hospital. Questionnaires at initial evaluation elicited information about bowel habits, soiling, previous evaluations, previous treatments, and parental attitudes. In 503 children with encopresis, the average age of referral dropped from 115 months during the earliest 5 years to 77 months during the most recent 5 years. Children who had soiling for >3 years before referral decreased from 63% to 12%. The use of barium enema before referral decreased from 14% to 5%, as did psychological evaluation, from 25% to 14%. Previous therapy with enemas decreased from 45% to 27%. Mineral oil use remained at approximately 50%, and 20% of children had no previous treatment. Symptoms at referral and parental attitudes did not change across the years. Children are now referred at an earlier age to our tertiary encopresis clinic. The number of invasive and psychological evaluations has decreased before referral. However, treatment by many primary care providers before the referral has not changed. These data may suggest that pediatricians have increased awareness of encopresis and greater appreciation of its primarily physical rather than psychological nature. Additional studies will be needed to determine how these factors affect outcome.

    To review the changes in permanent pacemaker implantation indications, pacing modes and patients' demographics over a 20-year period. We retrospectively retrieved data on patients who underwent first implantation of the pacemaker between 1-1-1991 and 31-12-2010. One thousand and nine (1,009) patients underwent a first pacemaker implantation during that period; 535 were men (53%), their mean age was 74.6±19.5 years; the highest rate of implanted pacemaker was in patients ranging in age from 70-79 years, however there was an increasing number of patients aged over 80 years. The median survival time after initial pacemaker implantation was 8 years. Syncope was the most common symptom (62.5%) and atrioventricular block was the most common electrocardiographic indication (56.4%) leading to pacemaker implantation. There was increased utilization of dual chamber and rate responsive pacemakers over the years. There was no difference regarding mode selection between genders. Pacemaker implantation rates have increased over a 20-year period. Dual chamber replaced most of the single ventricular chamber pacemaker and rate responsive pacemakers became the norm.

    The aim of this study was to evaluate the overall and progression-free survival of papillary thyroid carcinoma (PTC), comparing the American Thyroid Association (ATA) guideline for risk of recurrence with the TNM staging system with dynamic assessment at 2 years. This study is a retrospective analysis of 689 PTC patients over a 20-year period at a single center. Disease-free survival based on the TNM staging and ATA recurrence risk was calculated using Kaplan-Meier curves. Dynamic response assessment during the first 2 years was compared for both systems. Survival was calculated based on age, baseline resectability, and postthyroidectomy serum tumor marker levels. Six hundred eighty-nine (72.2%) of the total thyroid cancer patients had PTC. Four hundred sixty-nine patients were females, and 220 patients were males. The age range was 6 to 87 years. Five hundred thirty-five patients were resectable, and 56 patients were unresectable. One hundred fifty-one patients were excluded due to insufficient information on recurrence risk. By ATA categorization, 39% had low risk, no disease-related mortality; 44% had intermediate risk, 3 died; and 17% had high risk, 32 died. The 5-year disease-free survival was 54%, 26%, and 5% in low-, intermediate-, and high-risk groups, respectively. The log-rank test showed a significant difference in the percent survival (P < 0.01). TNM stage wise, in terms of survival, 1.3% in stage I, 2.2% in stage II, 0% in stage III, and 37.5% in stage IV died. The 20-year disease-free survival showed the following: stage I, 43%; stage II, 28%; stage III, 18%; and stage IV, 2%. There is significant difference in survival rate (P < 0.01). Both ATA risk classification and TNM staging were significant predictors of disease-free survival. On bivariate analysis, ATA classification (hazards ratio, 2.1; 95% confidence interval, 1.64-2.67; P = 0.001) was better predictive of overall survival versus TNM classification (hazards ratio, 1.3; 95% confidence

    To estimate the age-, gender-, and ethnicity-specific prevalence of amblyopia in children aged 5 to 15 years using data from the multi-country Refractive Error Study in Children (RESC). Population-based, cross-sectional study. Among 46 260 children aged 5 to 15 years who were enumerated from 8 sites in the RESC study, 39 551 had a detailed ocular examination and a reliable visual acuity (VA) measurement in 1 or both eyes. Information on ethnicity was available for 39 321 of these participants. This study focused on findings from the 39 321 children. The examination included VA measurements, evaluation of ocular alignment and refractive error under cycloplegia, and examination of the external eye, anterior segment, media, and fundus. The proportion of children aged 5 to 15 years with amblyopia in different ethnic cohorts. Amblyopia was defined as best-corrected visual acuity (BCVA) of ≤20/40 in either eye, with tropia, anisometropia (≥2 spherical equivalent diopters [D]), or hyperopia (≥+6 spherical equivalent D), after excluding children with fundus or anterior segment abnormalities. The overall prevalence of amblyopia was 0.74% (95% confidence interval, 0.64-0.83) with significant (P < 0.001) variation across ethnic groups: 1.43% in Hispanic, 0.93% in Chinese, 0.62% in Indian, 0.52% in Malay, 0.35% in Nepali, and 0.28% in African children. Amblyopia was not associated with age or gender. The most common cause of amblyopia was anisometropia. In this study, the prevalence of amblyopia varied with ethnicity and was highest in Hispanic children and lowest in African children. Most cases were unilateral and developed before the age of 5 years. The impact of changes of definitions on prevalence estimates is discussed. Copyright © 2015 American Academy of Ophthalmology.

    Aging, even in otherwise healthy subjects, is associated with declines in muscle mass, strength, and aerobic capacity. Older individuals respond favorably to exercise, suggesting that physical inactivity plays an important role in age-related functional decline. Conversely, physical activity and improved exercise capacity are associated with lower mortality risk in hypertensive individuals. However, the effect of exercise capacity in older hypertensive individuals has not been investigated extensively. A total of 2153 men with hypertension, aged ≥70 years (mean, 75 ± 4) from the Washington, DC, and Palo Alto Veterans Affairs Medical Centers, underwent routine exercise tolerance testing. Peak workload was estimated in metabolic equivalents (METs). Fitness categories were established based on peak METs achieved, adjusted for age: very-low-fit, 2.0 to 4.0 METs (n=386); low-fit, 4.1 to 6.0 METs (n=1058); moderate-fit, 6.1 to 8.0 METs (n=495); high-fit >8.0 METs (n=214). Cox proportional hazard models were applied after adjusting for age, body mass index, race, cardiovascular disease, cardiovascular medications, and risk factors. All-cause mortality was quantified during a mean follow-up period of 9.0 ± 5.5 years. There were a total of 1039 deaths or 51.2 deaths per 1000 person-years of follow-up. Mortality risk was 11% lower (hazard ratio, 0.89; 95% confidence interval, 0.86-0.93; P<0.001) for every 1-MET increase in exercise capacity. When compared with those achieving ≤4.0 METs, mortality risk was 18% lower (hazard ratio, 0.82; 95% confidence interval, 0.70-0.95; P=0.011) for the low-fit, 36% for the moderate-fit (hazard ratio, 0.64; 95% confidence interval, 0.52-0.78; P<0.001), and 48% for the high-fit individuals (hazard ratio, 0.52; 95% confidence interval, 0.39-0.69; P<0.001). These findings suggest that exercise capacity is associated with lower mortality risk in elderly men with hypertension. © 2014 American Heart Association, Inc.

    We estimated the association between legalizing medical marijuana and suicides. We obtained state-level suicide data from the National Vital Statistics System's Mortality Detail Files for 1990-2007. We used regression analysis to examine the association between medical marijuana legalization and suicides per 100 000 population. After adjustment for economic conditions, state policies, and state-specific linear time trends, the association between legalizing medical marijuana and suicides was not statistically significant at the .05 level. However, legalization was associated with a 10.8% (95% confidence interval [CI] = -17.1%, -3.7%) and 9.4% (95% CI = -16.1%, -2.4%) reduction in the suicide rate of men aged 20 through 29 years and 30 through 39 years, respectively. Estimates for females were less precise and sensitive to model specification. Suicides among men aged 20 through 39 years fell after medical marijuana legalization compared with those in states that did not legalize. The negative relationship between legalization and suicides among young men is consistent with the hypothesis that marijuana can be used to cope with stressful life events. However, this relationship may be explained by alcohol consumption. The mechanism through which legalizing medical marijuana reduces suicides among young men remains a topic for future study.

  11. Longitudinal Analysis of Adiponectin through 20-Year Type 1 Diabetes Duration.

    2015-01-01

    Little information exists on the trajectory and determinants of adiponectin, a possible insulin sensitizer and marker for inflammation and endothelial function, across the duration of type 1 diabetes. The Wisconsin Diabetes Registry Study followed an incident cohort ≤ 30 years of age when diagnosed with type 1 diabetes during 1987-1992 up to 20-year duration. Adiponectin was concurrently and retrospectively (from samples frozen at -80 °C) measured for those participating in a 20-year exam (n = 304), during 2007-2011. Adiponectin levels were higher in females, declined through adolescence, and increased with age thereafter. Lower levels were associated with greater body weight and waist circumference and with higher insulin dose, especially at longer diabetes durations. Higher levels were associated with higher HbA1c and, at longer durations, with higher albumin-creatinine ratio. Adiponectin levels showed consistency within individuals that was not explained by these factors. We conclude that markers for insulin resistance are associated with lower adiponectin, and markers for potential microvascular complications are associated with higher adiponectin. The previously reported relationship with HbA1c remains largely unexplained. Additional individual specific factors likely also influence adiponectin level. The relationship between adiponectin and urinary protein excretion may enable identification of those predisposed to kidney disease earlier in type 1 diabetes.

    Background/aim: This study aimed to determine the prevalence of urinary incontinence and to evaluate the relationship between urinary incontinence and quality of life in married women. Materials and methods: This is a cross-sectional study conducted among married women aged 20-49 years living in the vicinity of the Çökekler Community Clinic (Family Health Center) in Sakarya, Turkey, from 1 November 2011 to 15 April 2012. The study group consisted of 1161 women. Results: The frequency of urinary incontinence was 71.5% (n = 830). Out of a total of 830 patients with symptoms of urinary incontinence, mixed was the most frequently determined type (60.4%), followed by urge (33.9%) and then stress urinary incontinence (5.8%). The mean scores obtained by women with urinary incontinence from the general health perceptions and social functioning domains of the SF-36 survey were lower (P < 0.05 for each domain). Conclusion: Urinary incontinence was found to be a common problem among women, and it affects quality of life adversely. Recurrent urinary tract infection and advancing age were the key risk factors in the development of urinary incontinence.

    Despite considerable efforts to scale up voluntary medical male circumcision (VMMC) for HIV prevention in priority countries over the last five years, implementation has faced important challenges. Seeking to enhance the effect of VMMC programs for greatest and most immediate impact, the U. S. President's Plan for AIDS Relief (PEPFAR) supported the development and application of a model to inform national planning in five countries from 2013-2014. The Decision Makers' Program Planning Toolkit (DMPPT) 2.0 is a simple compartmental model designed to analyze the effects of client age and geography on program impact and cost. The DMPPT 2.0 model was applied in Malawi, South Africa, Swaziland, Tanzania, and Uganda to assess the impact and cost of scaling up age-targeted VMMC coverage. The lowest number of VMMCs per HIV infection averted would be produced by circumcising males ages 20-34 in Malawi, South Africa, Tanzania, and Uganda and males ages 15-34 in Swaziland. The most immediate impact on HIV incidence would be generated by circumcising males ages 20-34 in Malawi, South Africa, Tanzania, and Uganda and males ages 20-29 in Swaziland. The greatest reductions in HIV incidence over a 15-year period would be achieved by strategies focused on males ages 10-19 in Uganda, 15-24 in Malawi and South Africa, 10-24 in Tanzania, and 15-29 in Swaziland. In all countries, the lowest cost per HIV infection averted would be achieved by circumcising males ages 15-34, although in Uganda this cost is the same as that attained by circumcising 15- to 49-year-olds. The efficiency, immediacy of impact, magnitude of impact, and cost-effectiveness of VMMC scale-up are not uniform; there is important variation by age group of the males circumcised and countries should plan accordingly.

    2001-01-01

    The accuracy of ages measured using the 40Ar/39Ar technique is affected by uncertainties in the age of radiation fluence-monitor minerals. At present, there is lack of agreement about the ages of certain minerals used as fluence monitors. The accuracy of the age of a standard may be improved if the age can be measured using different decay schemes. This has been done by measuring ages on minerals from the Oligocene Fish Canyon Tuff (FCT) using the K-Ar, 40Ar/39Ar. Rb-Sr and U/Pb methods. K-Ar and 40Ar/39Ar total fusion ages of sanidine, biotite and hornblende yielded a mean age of 27.57 ?? 0.36 Ma. The weighted mean 40Ar/39Ar plateau age of sanidine and biotite is 27.57 ?? 0.18 Ma. A biotite-feldspar Rb-Sr isochron yielded an age of 27.44 ?? 0.16 Ma. The U-Pb data for zircon are complex because of the presence of Precambrian zircons and inheritance of radiogenic Pb. Zircons with 207Pb/235U < 0.4 yielded a discordia line with a lower concordia intercept of 27.52 ?? 0.09 Ma. Evaluation of the combined data suggests that the best age for FCT is 27.51 Ma.

  6. Variation of illite/muscovite 40Ar/39Ar age spectra during progressive low-grade metamorphism: an example from the US Cordillera

    2012-09-01

    40Ar/39Ar step-heating data were collected from micron to submicron grain-sizes of correlative illite- and muscovite-rich Cambrian pelitic rocks from the western United States that range in metamorphic grade from the shallow diagenetic zone (zeolite facies) to the epizone (greenschist facies). With increasing metamorphic grade, maximum ages from 40Ar/39Ar release spectra decrease, as do total gas ages and retention ages. Previous studies have explained similar results as arising dominantly or entirely from the dissolution of detrital muscovite and precipitation/recrystallization of neo-formed illite. While recognizing the importance of these processes in evaluating our results, we suggest that the inverse correlation between apparent age and metamorphic grade is controlled, primarily, by thermally activated volume diffusion, analogous to the decrease in apparent ages with depth observed for many thermochronometers in borehole experiments. Our results suggest that complete resetting of the illite/muscovite Ar thermochronometer occurs between the high anchizone and epizone, or at roughly 300 °C. This empirical result is in agreement with previous calculations based on muscovite diffusion parameters, which indicate that muscovite grains with radii of 0.05-2 μm should have closure temperatures between 250 and 350 °C. At high anchizone conditions, we observe a reversal in the age/grain-size relationship (the finest grain-size produces the oldest apparent age), which may mark the stage in prograde subgreenschist facies metamorphism of pelitic rocks at which neo-formed illite/muscovite crystallites typically surpass the size of detrital muscovite grains. It is also approximately the stage at which neo-formed illite/muscovite crystallites develop sufficient Ar retentivity to produce geologically meaningful 40Ar/39Ar ages. Results from our sampling transect of Cambrian strata establish a framework for interpreting illite/muscovite 40Ar/39Ar age spectra at different

    Aims The aim was to identify changes in patterns of alcohol consumption over a 20-year interval among older women and men, and to examine the associations between guideline-defined excessive drinking and late-life drinking problems. Design, Participants, and Measures A community sample of 719 adults between 55 and 65 years of age who consumed alcohol at or prior to baseline participated in a survey of alcohol consumption and drinking problems and was followed 10 years and 20 years later. Findings The likelihood of excessive drinking declined over the 20-year interval as adults matured into their 70s and 80s. However, at ages 75–85, 27% of women and 49% of men consumed more than 2 drinks per day or 7 drinks per week. At comparable guideline levels of alcohol consumption, older men were more likely to have drinking problems than were older women. Consumption of more than 2 drinks per day or 7 drinks per week was identified as a potential conservative guideline for identifying excessive drinking associated with an elevated likelihood of drinking problems. Conclusions A substantial percentage of older adults who consume alcohol engage in guideline-defined excessive drinking and incur drinking problems. The finding that older men may be more likely than older women to experience problems when they drink beyond guideline levels suggests that alcohol guidelines for men should not be set higher than those for women.

    Objective Poor nutrition is thought to predispose to externalizing behavior problems, but to date there appear to have been no prospective longitudinal studies testing this hypothesis. This study assessed whether 1) poor nutrition at age 3 years predisposes to antisocial behavior at ages 8, 11, and 17 years, 2) such relationships are independent of psychosocial adversity, and 3) IQ mediates the relationship between nutrition and externalizing behavior problems. Method The participants were drawn from a birth cohort (N=1,795) in whom signs of malnutrition were assessed at age 3 years, cognitive measures were assessed at ages 3 and 11 years, and antisocial, aggressive, and hyperactive behavior was assessed at ages 8, 11, and 17 years. Results In relation to comparison subjects (N=1,206), the children with malnutrition signs at age 3 years (N=353) were more aggressive or hyperactive at age 8 years, had more externalizing problems at age 11, and had greater conduct disorder and excessive motor activity at age 17. The results were independent of psychosocial adversity and were not moderated by gender. There was a dose-response relationship between degree of malnutrition and degree of externalizing behavior at ages 8 and 17. Low IQ mediated the link between malnutrition and externalizing behavior at ages 8 and 11. Conclusions These results indicate that malnutrition predisposes to neurocognitive deficits, which in turn predispose to persistent externalizing behavior problems throughout childhood and adolescence. The findings suggest that reducing early malnutrition may help reduce later antisocial and aggressive behavior. PMID:15514400

    Marijuana smoke contains many of the same constituents as tobacco smoke, but whether it has similar adverse effects on pulmonary function is unclear. To analyze associations between marijuana (both current and lifetime exposure) and pulmonary function. The Coronary Artery Risk Development in Young Adults (CARDIA) study, a longitudinal study collecting repeated measurements of pulmonary function and smoking over 20 years (March 26, 1985-August 19, 2006) in a cohort of 5115 men and women in 4 US cities. Mixed linear modeling was used to account for individual age-based trajectories of pulmonary function and other covariates including tobacco use, which was analyzed in parallel as a positive control. Lifetime exposure to marijuana joints was expressed in joint-years, with 1 joint-year of exposure equivalent to smoking 365 joints or filled pipe bowls. Forced expiratory volume in the first second of expiration (FEV(1)) and forced vital capacity (FVC). Marijuana exposure was nearly as common as tobacco exposure but was mostly light (median, 2-3 episodes per month). Tobacco exposure, both current and lifetime, was linearly associated with lower FEV(1) and FVC. In contrast, the association between marijuana exposure and pulmonary function was nonlinear (P < .001): at low levels of exposure, FEV(1) increased by 13 mL/joint-year (95% CI, 6.4 to 20; P < .001) and FVC by 20 mL/joint-year (95% CI, 12 to 27; P < .001), but at higher levels of exposure, these associations leveled or even reversed. The slope for FEV(1) was -2.2 mL/joint-year (95% CI, -4.6 to 0.3; P = .08) at more than 10 joint-years and -3.2 mL per marijuana smoking episode/mo (95% CI, -5.8 to -0.6; P = .02) at more than 20 episodes/mo. With very heavy marijuana use, the net association with FEV(1) was not significantly different from baseline, and the net association with FVC remained significantly greater than baseline (eg, at 20 joint-years, 76 mL [95% CI, 34 to 117]; P < .001).

    To investigate the risk of hypothyroidism after radioiodine (131I) treatment for hyperfunctioning thyroid nodules. Retrospective analysis of patients treated with 131I for hyperfunctioning thyroid nodules and followed up for a maximum of 20 years. A total of 346 patients treated with 131I in the years 1975-95, for a single hyperfunctioning nodule. Hypothyroidism was defined as TSH levels > 3.7 mU/l. Kaplan-Meier survival analysis was used to analyse permanence of euthyroidism after 131I. A stepwise Cox proportional hazard model was used to identify factors influencing the progression to hypothyroidism. The cumulative incidence of hypothyroidism was 7.6% at 1 year, 28% at 5 years, 46% at 10 years and 60% at 20 years. Age (P < 0.01), 24-th 131I uptake (P < 0.05) and previous treatment with methimazole (MMI, P < 0.1) were associated with a faster progression towards hypothyroidism, while thyroid and nodule size, thyroid status at diagnosis and degree of extranodular thyroid parenchymal suppression had no influence. In hyperthyroid patients with partial parenchymal suppression, however, previous MMI treatment was the most important prognostic factor (P < 0.01). After 20 years of follow-up, 60% of patients treated with 131I for a single hyperfunctioning nodule are hypothyroid. Factors increasing the risk of hypothyroidism are age, 131I uptake and MMI pretreatment. The prognostic value of this last factor, however, depends on the degree of suppression of the extranodular thyroid parenchyma at the scan.

  16. Ar-40/Ar-39 Age of Hornblende-bearing R Chondrite LAP 04840

    Chondrites have a complex chronology due to several variables affecting and operating on chondritic parent bodies such as radiogenic heating, pressure and temperature variation with depth, aqueous alteration, and shock or impact heating [1]. Unbrecciated chondrites can record ages from 4.56 to 4.4 Ga that represent cooling in small parent bodies. Some brecciated chondrites exhibit younger ages (<<4 to 4.4 Ga) that may reflect the age of brecciation, disturbance, or shock and impact events (<< 4 Ga). A unique R chondrite was recently found in the LaPaz Icefield of Antarctica - LAP 04840 [2]. This chondrite contains approx.15% hornblende and trace amounts of biotite, making it the first of its kind. Studies have revealed an equigranular texture, mineral equilibria yielding equilibration near 650-700 C and 250-500 bars, hornblende that is dominantly OH-bearing (very little Cl or F), and high D/H ratios [8,9,10]. To help gain a better understanding of the origin of this unique sample, we have measured the Ar-40/Ar-39 age. Age of 4.290 +/- 0.030 Ga is younger than one would expect for a sample that has cooled within a small body [4], and one might instead attribute the age to a younger shock event, On the other hand, there is no evidence for extensive shock in this meteorite (shock stage S2; [3]), so this sample may have been reannealed after the shock event. This age is similar to Ar-Ar ages determined for some other R chondrites

  19. The evolution, argon diffusion properties, and 40Argon/39Argon ages of detachment-related fault rocks in the footwalls of the Whipple and Chemehuevi Mountains, Southeastern, California

    NASA Astrophysics Data System (ADS)

    Hazelton, Garrett Blaine

    Furnace and laser spot methods of obtaining 40Ar/ 39Ar ages from fine-grained cataclasite and pseudotachylyte are compared and evaluated in terms of protolith, faulting, and cooling age components. These methods are applied to fault rocks from outcrop-scale, small-displacement, brittle detachment faults (minidetachments or MDF's) that cut mid-crustal rocks from the footwalls of brittle, large-displacement (>20 km), top-to-the-NE, low-angle normal (i.e., detachment) faults in the Whipple (WM) and Chemehuevi Mountains (CM), SE California. Mid-Tertiary extension affected both areas from ˜26 Ma to ˜11--8 Ma. Rapid footwall cooling began at ˜22 Ma. WM-CM furnace ages range from 22.0 +/- 1.3 to 14.6 +/- 0.6 Ma, CM laser ages from 29.9 +/- 3.7 to 15.7 +/- 1.2 Ma. These ages are younger than host protolith formation and record detachment faulting or footwall cooling. At least 50 MDF's were mapped; they typically cut all basement fabrics. Brittle MDFand detacriment-generated fault rocks are texturally similar, but some in the WM are plastically deformed. Fault rock matrix was mechanically extracted, optically studied, probed to characterize bulk mineralogy. K-feldspar grains are the primary source of fault rock-derived Ar. The laser provides high spatial resolution and the furnace method yields the Ar diffusion properties of fault rock matrix. Both methods yield reproducible results, but ages are difficult to interpret without an established geothermochronologic context. Fault rock 40Ar/39Ar measurements reveal: (1) closure temperatures of 140--280°C (at 100°C/Myr); (2) activation energies ranging from 33--50 kcal/mol; (3) individual K-feldspar grain ages of 55--5 Ma; (4) unanticipated and poorly understood low-temperature diffusion behavior; (5) little difference between pseudotachylyte and cataclasite matrix diffusion and age results; (6) that pre-analysis sample characterization is requisite. The diffusion properties of prepared glasses (47--84% SiO2) were also

    Early malnutrition is linked to poor cognition, but long-term effects have not been extensively examined and psychosocial confounds have not always been controlled. To test the hypothesis that malnutrition at age 3 years will be associated with poorer cognitive ability at age 11 years independent of psychosocial confounds. A prospective, longitudinal study of a birth cohort of 1559 children originally assessed at age 3 years for malnutrition (low hemoglobin level, angular stomatitis, kwashiorkor, and sparse, thin hair) and followed up to age 11 years. A community sample of 1559 children (51.4% boys and 48.6% girls) born between September 1, 1969, and August 31, 1970, in 2 towns in the island of Mauritius, with 68.7% Indians and 25.7% Creoles (African origin). Verbal and spatial ability measured at ages 3 and 11 years and reading, scholastic ability, and neuropsychologic performance measured at age 11 years. Malnourished children had poorer cognition at both ages. Deficits were stable across time, applied to all sex and ethnic groups, and remained after controlling for multiple measures of psychosocial adversity. Children with 3 indicators of malnutrition had a 15.3-point deficit in IQ at age 11 years. Malnutrition at age 3 years is associated with poor cognition at age 11 years independent of psychosocial adversity. Promoting early childhood nutrition could enhance long-term cognitive development and school performance, especially in children with multiple nutritional deficits.

    Importance This study provides further evidence from a national sample to generalize the relationship between depression and vision loss to adults across the age spectrum. Better recognition of depression among people reporting reduced ability to perform routine activities of daily living due to vision loss is warranted. Objectives To estimate, in a national survey of US adults 20 years of age or older, the prevalence of depression among adults reporting visual function loss and among those with visual acuity impairment. The relationship between depression and vision loss has not been reported in a nationally representative sample of US adults. Previous studies have been limited to specific cohorts and predominantly focused on the older population. Design The National Health and Nutrition Examination Survey (NHANES) 2005–2008. Setting A cross-sectional, nationally representative sample of adults, with prevalence estimates weighted to represent the civilian, noninstitutionalized US population. Participants A total of 10 480 US adults 20 years of age or older. Main Outcome Measures Depression, as measured by the 9-item Patient Health Questionnaire depression scale, and vision loss, as measured by visual function using a questionnaire and by visual acuity at examination. Results In 2005–2008, the estimated crude prevalence of depression (9-item Patient Health Questionnaire score of ≥10) was 11.3% (95% CI, 9.7%–13.2%) among adults with self-reported visual function loss and 4.8% (95% CI, 4.0%–5.7%) among adults without. The estimated prevalence of depression was 10.7% (95% CI, 8.0%–14.3%) among adults with presenting visual acuity impairment (visual acuity worse than 20/40 in the better-seeing eye) compared with 6.8% (95% CI, 5.8%–7.8%) among adults with normal visual acuity.

  2. 40Ar-39Ar Age Constraints on Volcanism and Tectonism in the Terror Rift of the Ross Sea, Antarctica

    USGS Publications Warehouse

    2007-01-01

    Volcanic sills and dikes inferred from seismic reflection profiles and geophysical studies of the Ross Sea are thought to be related to the rift basins in the region, and their emplacement to be coeval with extension. However, lack of precise geochronology in the Terror Rift of the Ross Sea region has left these inferred relationships poorly constrained and has hindered neotectonic studies, because of the large temporal gaps between seismic reflectors of known ages. New 40Ar/39Ar geochronology presented here for submarine volcanic rocks provides better age constraints for neotectonic interpretations within the Terror Rift. Several samples from seamounts yielded young ages between 156 ± 21 and 122 ± 26 Ka. These ages support interpretations that extension within the Terror Rift was active at least through the Pleistocene. Three evenly spaced samples from the lowermost 100 m of Franklin Island range in age from 3.28 ± 0.04 to 3.73 ± 0.05 Ma. These age determinations demonstrate that construction of a small volcanic edifice such as Franklin Island took at least several hundred thousand years, and therefore that much larger ones in the Erebus Volcanic Province are likely to have taken considerably longer than previously inferred. This warrants caution in applying a limited number of age determinations to define the absolute ages of events in the Ross Sea region

    To assess the growth pattern of children in Yazd, and compare it with standards outlined by the World Health Organisation. The cross-sectional study, which was conducted in 2009, involved 20 guidance schools of Yazd city. A total of 1921 children were chosen by simple cluster method and general demographic and anthropometric information regarding the subjects was extracted from students' health identification booklets. Data was analysed through SPSS. The mean values of height in 7th and 12th years of age were 119 +/- 8.8cm and 150 +/- 6.6cm in boys and 117 +/- 5.97cm and 152 +/- 7.3cm in girls respectively. The mean values of weight in 7th and 12th years of age were 20 +/- 3.39kg and 39 +/- 1kg in boys and 20 +/- 3.78kg and 41 +/- 1.07kg in girls respectively. These values generally were below the values set by the World Health Organisation till the 9th year of age, and above them beyond the 9th year. The growth pattern among children in Yazd is better than some of the other provinces in Iran. Larger studies are needed for generating Iran-specific standard for better assessment of the growth and nutritional status of Iranian children.

    Little information exists on the trajectory and determinants of adiponectin, a possible insulin sensitizer and marker for inflammation and endothelial function, across the duration of type 1 diabetes. The Wisconsin Diabetes Registry Study followed an incident cohort ≤30 years of age when diagnosed with type 1 diabetes during 1987–1992 up to 20-year duration. Adiponectin was concurrently and retrospectively (from samples frozen at −80°C) measured for those participating in a 20-year exam (n = 304), during 2007–2011. Adiponectin levels were higher in females, declined through adolescence, and increased with age thereafter. Lower levels were associated with greater body weight and waist circumference and with higher insulin dose, especially at longer diabetes durations. Higher levels were associated with higher HbA1c and, at longer durations, with higher albumin-creatinine ratio. Adiponectin levels showed consistency within individuals that was not explained by these factors. We conclude that markers for insulin resistance are associated with lower adiponectin, and markers for potential microvascular complications are associated with higher adiponectin. The previously reported relationship with HbA1c remains largely unexplained. Additional individual specific factors likely also influence adiponectin level. The relationship between adiponectin and urinary protein excretion may enable identification of those predisposed to kidney disease earlier in type 1 diabetes. PMID:25950008

    To evaluate the role of extracurricular physical activity and sedentary behavior at preschool and primary school age on working memory at primary school age and adolescence, respectively. This prospective study was based on a birth cohort across 4 Spanish regions. In the 3 younger subcohorts (n = 1093), parents reported lifestyle habits of child at age 4 years of age on a questionnaire, and children performed a computerized working memory task at 7 years of age. In the older subcohort (n = 307), the questionnaire was completed at 6 years of age and working memory was tested at 14 years of age. Adjusted regression models were developed to investigate the associations between lifestyle habits and working memory. Low extracurricular physical activity levels at 4 years of age were associated with a nonsignificant 0.95% (95% CI -2.81 to 0.92) reduction of correct responses in the working memory task at age 7 years of age. Low extracurricular physical activity levels at 6 years of age were associated with a 4.22% (95% CI -8.05 to -0.39) reduction of correct responses at age 14 years. Television watching was not associated with working memory. Other sedentary behaviors at 6 year of age were associated with a 5.07% (95% CI -9.68 to -0.46) reduction of correct responses in boys at 14 years of age. Low extracurricular physical activity levels at preschool and primary school ages were associated with poorer working memory performance at primary school age and adolescence, respectively. High sedentary behavior levels at primary school age were related negatively to working memory in adolescent boys. Copyright © 2017 Elsevier Inc. All rights reserved.

    IMPORTANCE Modifying levels of factors associated with age-related macular degeneration (AMD) may decrease the risk for visual impairment in older persons. OBJECTIVE To examine the relationships of markers of inflammation, oxidative stress, and endothelial dysfunction to the 20-year cumulative incidence of early AMD. DESIGN, SETTING, AND PARTICIPANTS This longitudinal population-based cohort study involved a random sample of 975 persons in the Beaver Dam Eye Study without signs of AMD who participated in the baseline examination in 1988-1990 and up to 4 follow-up examinations in 1993-1995, 1998-2000, 2003-2005, and 2008-2010. EXPOSURES Serum markers of inflammation (high-sensitivity C-reactive protein, tumor necrosis factor-α receptor 2, interleukin-6, and white blood cell count), oxidative stress (8-isoprostane and total carbonyl content), and endothelial dysfunction (soluble vascular cell adhesion molecule-1 and soluble intercellular adhesion molecule-1) were measured. Interactions with complement factor H (rs1061170), age-related maculopathy susceptibility 2 (rs10490924), complement component 3 (rs2230199), and complement component 2/complement factor B (rs4151667) were examined using multiplicative models. Age-related macular degeneration was assessed from fundus photographs. MAIN OUTCOMES AND MEASURES Early AMD defined by the presence of any size drusen and the presence of pigmentary abnormalities or by the presence of large-sized drusen (≥125-μm diameter) in the absence of late AMD. RESULTS The 20-year cumulative incidence of early AMD was 23.0%. Adjusting for age, sex, and other risk factors, high-sensitivity C-reactive protein (odds ratio comparing fourth with first quartile, 2.18; P = .005), tumor necrosis factor-α receptor 2 (odds ratio, 1.78; P = .04), and interleukin-6 (odds ratio, 1.78; P = .03) were associated with the incidence of early AMD. Increased incidence of early AMD was associated with soluble vascular cell adhesion molecule

    According to the 2013 analysis of the Institute of Health Metrics, high body mass index values are the most important risk factor for disease in Spain. Consequently, we describe the prevalence of total obesity and abdominal obesity in the Spanish adult population (25-64 years) for 2014-2015. The sample was taken from the ENPE study, a cross-sectional study with a representative sample of the noninstitutionalized population (n = 6800) carried out between May 2014 and May 2015. This analysis refers to the population between age 25 and 64 years (n = 3966). The anthropometric measurements were performed by trained observers at participants' homes according to standard international protocols. Body mass index ≥ 25 was defined as overweight and ≥ 30 as obesity. Abdominal obesity was classified as waist > 102 cm in men and > 88 cm in women. The estimated prevalence of overweight in the Spanish adult population (25-64 years) was 39.3% 95% confidence interval [95%CI], 35.7%-42.9%). The prevalence of general obesity was 21.6% (95%CI, 19.0%-24.2%) and, more specifically, was 22.8% (95%CI, 20.6%-25.0%) among men and 20.5% (95%CI, 18.5%-22.5%) among women, and rose with age. The prevalence of abdominal obesity was estimated at 33.4% (95%CI, 31.1%-35.7%) and was higher among women (43.3%; 95%CI, 41.1%-45.8%) than among men (23.3%; 95%CI, 20.9%-25.5%), and also rose with age. The prevalence of general obesity and abdominal obesity in Spain is high, although the distribution differs according to autonomous community. A comparison with earlier data reveals a considerable increase in overweight, indicating the need for routine monitoring and comprehensive initiatives.

    From 1975 to 1979 in the district of the City of Karl-Marx-Stadt 91,130 females at the age between 20 and 65 years were summoned to a gynaecologico-cardiological mass examination which was supported by computer. 56,460 females underwent the examination. According to the WHO-criteria two measurements of blood pressure were carried out, when increased blood pressure was present a third one and a fourth one by an examination group. A diagnostic standard programme was used. In the second measurement of blood pressure we established 19.8% of patients with hypertension and 28.6% patients with borderline values. 52.8% of the hypertensions were known. Of 10,685 females with known or established hypertension 10.1% underwent an optimum therapy. On the basis of these results a programme for the fight against hypertension was developed for the county Karl-Marx-Stadt.

  15. The effect of thermal resetting and recrystallisation on white mica 40Ar/39Ar ages during retrograde metamorphism on Syros, Greece

    White mica 40Ar/39Ar dating is a proven powerful tool for constraining timing of metamorphism, deformation and exhumation. However, in high-pressure metamorphic rocks, dating often results in wide age ranges which are not in agreement with constraints from other isotopic systems, indicating that geological and chemical processes complicate straightforward 40Ar/39Ar dating. In this research project, white mica ages from rocks of the Cycladic Blueschist Unit on Syros, Greece with contrasting rheology and strain mechanisms are compared, in order to better understand the role of deformation, recrystallization and fluid flow on 40Ar/39Ar ages of white mica during retrograde metamorphism. Resulting ages vary along different sections on the island, inconsistent with other isotopic constraints on eclogite-blueschist metamorphism (55-50 Ma) and greenschist overprinting (41-30 Ma). Two end-member models are possible: 1) Results represent continuous crystallization of white mica while moving from blueschist to greenschist conditions in the metamorphic P-T loop, or 2) white mica equilibrated in eclogite-blueschist conditions and their diffusion systematics were progressively perturbed during greenschist overprinting. The single grain fusion analyses yielded contrasting age distributions, which indicate contrasts in degree of re-equilibration during retrograde metamorphism. Step wise heating of larger grain populations resulted in flat plateau shapes, providing no evidence for partial resetting. Electron microprobe measurements of Si per formula unit, as a proxy for pressure during crystallisation, do not explain age variation within sections or on the island scale. The previously unreported north-south age trend and age ranges per sample, as shown only in the 40Ar/39Ar system of the metapelitic and marble lithologies, contains key information that will allow us to test between different scenarios for age formation. Excess argon infiltration at this stage seems to have been of

    Levetiracetam is a new anticonvulsant, which works to block high-voltage-activated Ca(++) channels in children, for partial-onset seizures. Reports of clinical experience with pediatric ingestions are minimal. The purpose of this study was to characterize the toxicity of accidental levetiracetam exposures in children less than 6 years of age. This was an 11-year retrospective observational case series of pediatric (< 6 years old) levetiracetam ingestions reported to a Poison Control System from 2002 to 2013. Case narratives were individually reviewed to collect desired information on exposure and clinical course. Inclusion criteria were levetiracetam as a single ingested medication, age less than 6 years, treatment in a health care facility, and followed to a known outcome. Eighty-two cases met inclusion criteria with 55% female patients and overall median age of 2.0 years (range: 1-60 months). The levetiracetam dose ingested was reported in 69 (84.1%) cases, with exact dose (median dose, 45.0 mg/kg; range, 10.5-1429 mg/kg) reported in 33 cases (40.2%). Of these, twenty-nine cases (88%) involved the oral solution formulation and 28 cases (85%) had unintentional therapeutic error as the cause of the exposure. No dose-response relationship was demonstrated; however, the odds of a levetiracetam-naive patient, (median dose, 26.9 mg/kg; N = 15) with an unintentional exposure, developing drowsiness or ataxia was 6 times that of a patient who was not naïve to levetiracetam (median dose, 70.1 mg/kg; N = 20) (Odds ratio [OR], 6.0; 95% confidence interval [CI], 1.03-35.91).Of the 82 cases, 17 (20.7%) developed untoward clinical effects of drowsiness and/or ataxia. Eighty patients (97.6%) were treated and discharged from the emergency department, and two patients (2.4%) were admitted. The two patients admitted included a two-month old who was accidentally given a dose 10 times that of her usual dose and a 3-year old who was lethargic on arrival to the hospital after

    In a group of 46,000 North-American Adventist women aged 40 and above, we investigated the relationships between body mass index (BMI, kg/m(2)) at age 20 and the proportion of women who reported at least one miscarriage, periods with irregular menstruation or failing to become pregnant even if trying for more than one straight year. Approximately 31, 14 and 17 %, respectively, reported the three different problems related to reproduction. Positive age- and marital status adjusted relationships were found between BMI at age 20 and periods with irregular menstruation or failing to become pregnant even if trying for more than 1 year, but not with the risk of miscarriages. Women with BMI ≥ 32.5 kg/m(2) when aged 20 had approximately 2.0 (95 % CI: 1.6, 2.4) and 1.5 (95 % CI: 1.3, 1.9) higher odds for irregular periods or failing to get pregnant, respectively, than women with BMI in the 20-24.9 kg/m(2) bracket. These relationships were consistently found in a number of strata of the population, including the large proportion of the women who never had smoked or never used alcohol. Underweight (BMI < 18.5 kg/m(2)) when aged 20 marginally (approximately 15 %) increased the risk of failing to get pregnant within a year. Thus, obesity at age 20 increases the risk of reporting some specific reproductive problems, but not the risk of miscarriages.

    AIM: To investigate the safety and efficacy of peroral endoscopic myotomy (POEM) for achalasia in patients aged ≥ 65 years. METHODS: From November 2011 to August 2014, 15 consecutive patients (aged ≥ 65 years) diagnosed with achalasia were prospectively recruited and all underwent POEM at our institution. Eckardt score, lower esophageal sphincter (LES) pressure, esophageal diameter, SF-36 questionnaire, and procedure-related complications were used to evaluate the outcomes. RESULTS: All 15 patients were treated successfully by POEM, with a median operation time of 55 min. Median myotomy length was 10 cm. Three patients underwent circular myotomy and 12 full-thickness myotomies. Symptoms remitted in all cases during post-POEM follow-up of 6-39 mo. Eckardt score reduced significantly (pre-operation vs post-operation: 8.0 vs 1.0, P < 0.05). Median LES pressure decreased from 27.4 to 9.6 mmHg (P < 0.05). Median diameter of the esophagus was significantly decreased (pre-operation vs post-operation: 51.0 mm vs 30.0 mm, P < 0.05). Only one patient had reflux, which was resolved with oral proton pump inhibitors. No serious complications related to POEM were found. The quality of life of the 15 patients improved significantly after POEM. CONCLUSION: POEM is a safe and effective technique for treatment of achalasia in patients aged ≥ 65 years, with improvement in symptoms and quality of life. PMID:26290645

    Abstract Background The herpes zoster subunit vaccine (HZ/su), consisting of varicella-zoster virus glycoprotein E (gE) and AS01B Adjuvant System, was highly efficacious in preventing herpes zoster in the ZOE-50 and ZOE-70 trials. We present immunogenicity results from those trials. Methods Participants (ZOE-50: ≥50; ZOE-70: ≥70 years of age) received 2 doses of HZ/su or placebo, 2 months apart. Serum anti-gE antibodies and CD4 T cells expressing ≥2 of 4 activation markers assessed (CD42+) after stimulation with gE-peptides were measured in subcohorts for humoral (n = 3293) and cell-mediated (n = 466) immunogenicity. Results After vaccination, 97.8% of HZ/su and 2.0% of placebo recipients showed a humoral response. Geometric mean anti-gE antibody concentrations increased 39.1-fold and 8.3-fold over baseline in HZ/su recipients at 1 and 36 months post-dose 2, respectively. A gE-specific CD42+ T-cell response was shown in 93.3% of HZ/su and 0% of placebo recipients. Median CD42+ T-cell frequencies increased 24.6-fold (1 month) and 7.9-fold (36 months) over baseline in HZ/su recipients and remained ≥5.6-fold above baseline in all age groups at 36 months. The proportion of CD4 T cells expressing all 4 activation markers increased over time in all age groups. Conclusions Most HZ/su recipients developed robust immune responses persisting for 3 years following vaccination. Clinical Trials Registration NCT01165177; NCT01165229. PMID:29529222

    Despite a demonstrated relationship between sexual behaviors and health, including clinical risks, little is known about contemporary sexual behavior. To assess the rates of sexual behavior among adolescents and adults in the United States. We report the recent (past month, past year) and lifetime prevalence of sexual behaviors in a nationally representative probability sample of 5,865 men and women ages 14 to 94 in the United States (2,936 men, 2,929 women). Behaviors assessed included solo masturbation, partnered masturbation, giving and receiving oral sex, vaginal intercourse, and anal intercourse. Masturbation was common throughout the lifespan and more common than partnered sexual activities during adolescence and older age (70+). Although uncommon among 14- to 15-year olds, in the past year 18.3% of 16- to 17-year-old males and 22.4% of 16- to 17-year-old females performed oral sex with an other-sex partner. Also in the past year, more than half of women and men ages 18 to 49 engaged in oral sex. The proportion of adults who reported vaginal sex in the past year was highest among men ages 25-39 and for women ages 20-29, then progressively declined among older age groups. More than 20% of men ages 25-49 and women ages 20-39 reported anal sex in the past year. Same-sex sexual behaviors occurring in the past year were uncommonly reported. Men and women engage in a diverse range of solo and partnered sexual behaviors throughout the life course. The rates of contemporary sexual behavior provided in this report will be valuable to those who develop, implement, and evaluate programs that seek to improve societal knowledge related to the prevalence of sexual behaviors and to sexual health clinicians whose work to improve sexual health among the population often requires such rates of behavior. © 2010 International Society for Sexual Medicine.

    To estimate (1) productive life years (PLYs) lost because of chronic conditions in Australians aged 45-64 years from 2010 to 2030, and (2) the impact of this loss on gross domestic product (GDP) over the same period. A microsimulation model, Health&WealthMOD2030, was used to project lost PLYs caused by chronic conditions from 2010 to 2030. The base population consisted of respondents aged 45-64 years to the Australian Bureau of Statistics Survey of Disability, Ageing and Carers 2003 and 2009. The national impact of lost PLYs was assessed with Treasury's GDP equation. Lost PLYs due to chronic disease at 2010, 2015, 2020, 2025 and 2030 (ie, whole life years lost because of chronic disease); the national impact of lost PLYs at the same time points (GDP loss caused by PLYs); the effects of population growth, labour force trends and chronic disease trends on lost PLYs and GDP at each time point. Using Health&WealthMOD2030, we estimated a loss of 347,000 PLYs in 2010; this was projected to increase to 459,000 in 2030 (32.28% increase over 20 years). The leading chronic conditions associated with premature exits from the labour force were back problems, arthritis and mental and behavioural problems. The percentage increase in the number of PLYs lost by those aged 45-64 years was greater than that of population growth for this age group (32.28% v 27.80%). The strongest driver of the increase in lost PLYs was population growth (accounting for 89.18% of the increase), followed by chronic condition trends (8.28%). Our study estimates an increase of 112 000 lost PLYs caused by chronic illness in older workers in Australia between 2010 and 2030, with the most rapid growth projected to occur in men aged 55-59 years and in women aged 60-64 years. The national impact of this lost labour force participation on GDP was estimated to be $37.79 billion in 2010, increasing to $63.73 billion in 2030.

    To present progress toward Healthy People 2010 vaccination objectives for adolescents aged 13-15 years, and to determine how much catch-up and routine vaccination was administered at the recommended ages of 11-12 years. Data from the 1997-2003 National Health Interview Survey were evaluated. In the first analysis, vaccination coverage levels for adolescents aged 13-15 years were determined for each survey year. Main outcome measures include the percent of adolescents who had received the three-dose hepatitis B vaccine (Hep B) series, the two-dose measles/mumps/rubella vaccine (MMR) series, the tetanus and diphtheria toxoids (Td) booster, and one dose of varicella vaccine. In the second analysis, data from all survey years were combined and vaccination dates were analyzed to determine the percentage of adolescents who were missing any vaccines at ages 11-12 and received them at that age. Data for varicella vaccine were sufficient only for the first analysis. Among the approximately 15%-20% of respondents who reported vaccination history from records in the home and who were reporting on a 13-15-year-old, coverage with three doses of Hep B increased significantly during 1997-2001, from 15.2% to 55.0%. Coverage with MMR and Td fluctuated, with no significant increase; highs were 76.7% for MMR in 2003 and 36.2% for Td in 2002. Examination of vaccination dates for all surveyed adolescents showed that among 11-12-year-olds who needed catch-up vaccine, 0.6%-31.3% were brought up to date for Hep B and 22.1%-31.8% were brought up to date for MMR. For Td, 2.6%-15.4% of 11-12-year-olds who had not previously received Td received the vaccine. Vaccination coverage among adolescents aged 13-15 years was below the Healthy People 2010 goals of 90%, but generally increased over the survey years. However, the suboptimal delivery of needed vaccines during ages 11 and 12 is concerning in light of recent vaccine recommendations targeted at this age. Continuing to focus on strategies to

    To monitor the incidence change of acute coronary heart events in the all-ages farmers in Panyu District, Guangzhou City during 1991-2001 and 2010-2011. The surveillance on the same defined population as that from the PRC-USA cooperative epidemiologic project on the cardiovascular and pulmonary diseases 30-year ago was carried out in Panyu, Guangzhou in 1991-2001 and 2010-2011. The crude incidence of acute coronary events and the age-standardized incidence rate were calculated by the year, gender and age, and standardized with the world standard population age distribution. Incidences at the two different periods were compared. The annual average changing rate of the incidence was obtained by the regression analysis methods. In the 11 consecutive years of 1991-2001, a upward trend on the incidence of acute coronary events among the farmers in women in Panyu District was found (P < 0.05). The incidence of the acute coronary events in the year of 2010-2011 was significantly higher than that in the year of 1991 to 2001 [34.06 per 100 000 (age-adjusted rate as 28.50 per 100 000) versus 16.14 per 100 000 (age-adjusted rate as 16.57 per 100 000), P < 0.05]. The age-adjusted rate increased by 83.04%. Peak incidence of acute coronary events in males was noticed in 75-79 age group, and in 80-84 age group in females. Comparing to the period of 1991-2001, the largest incidence increases appeared in the age groups of 35-39 and 75-79 years in males, while in the age groups of 50-54 and 65-69 years in females. Up to 47.37% (36/76) events occurred on the age group older than 75 years, raised by 40.44% comparing to that in 1991-2001 (33.73%, 56/166). The incidence of acute coronary events among farmers in Panyu District is at middle or low level of China but there is an increasing trend in acute coronary incidence from 1991 to 2011. Our results suggest that the prevention and treatment on acute coronary syndrome should be strengthened, and especially on the age group with the

    Improvements in implant design and surgical technique of unicondylar knee arthroplasty have led to reduced revision rates, but patient selection seems to be crucial for success of such arthroplasties. The purpose of the present study was to analyze the 5-year implant survival rate of unicondylar knee replacements in Germany and to identify patient factors associated with an increased risk of revision, including >30 comorbid conditions. Using nationwide billing data of the largest German health-care insurance for inpatient hospital treatment, we identified patients who underwent unicondylar knee arthroplasty between 2006 and 2012. Kaplan-Meier survival curves with revision as the end point and log-rank tests were used to evaluate 5-year implant survival. A multivariable Cox regression model was used to determine factors associated with revision. The risk factors of age, sex, diagnosis, comorbidities, type of implant fixation, and hospital volume were analyzed. Hazard ratios (HRs) and 95% confidence intervals (95% CIs) were calculated. During the study period, a total of 20,946 unicondylar knee arthroplasties were included. The number of unicondylar knee arthroplasties per year increased during the study period from 2,527 in 2006 to 4,036 in 2012. The median patient age was 64 years (interquartile range, 56 to 72 years), and 60.4% of patients were female. During the time evaluated, the 1-year revision rate decreased from 14.3% in 2006 to 8.7% in 2011. The 5-year survival rate was 87.8% (95% CI, 87.3% to 88.3%). Significant risk factors (p < 0.05) for unicondylar knee arthroplasty revision were younger age (the HR was 2.93 [95% CI, 2.48 to 3.46] for patient age of <55 years, 1.86 [95% CI, 1.58 to 2.19] for 55 to 64 years, and 1.52 [95% CI, 1.29 to 1.79] for 65 to 74 years; patient age of >74 years was used as the reference); female sex (HR, 1.18 [95% CI, 1.07 to 1.29]); complicated diabetes (HR, 1.47 [95% CI, 1.03 to 2.12]); depression (HR, 1.29 [95% CI, 1.06 to 1

However, the distributions of Ar-39 and C-14 are different due to the large difference in their half-lives (269 years and 5730 years respectively). Measurement of both tracers provides information on the relative importance of advection and mixing in the deep ocean and provides more accurate transit times than can be obtained with only one of these tracers. In the Atlantic Ocean, where the deep water is roughly a two-end member mixture of northern component and southern component water, the age of the two components can be estimated from simultaneous measurement of Ar-39 and C-14. The few existing measurements suggest that the northern component water has an age range of 40-200 years and the southern component water a range of 60-600 years. Development of the ATTA method for measuring radioactive noble gases offers great potential to dramatically increase the number of samples that can be measured for Ar-39, which could greatly improve our understanding of mixing and circulation in the deep ocean.

  14. Interpretation of 40Ar/39Ar Age-spectra in Low-grade Polymetamorphic Rocks: The Importance of Petrologic constraints

    40Ar/39Ar age-spectra of white micas from low-grade polymetamorphic terranes can be difficult to interpret, because these low-grade rocks frequently have multiple generations of cleavage-forming white mica that grew at temperatures below their closure for diffusion of argon (~350°C). Under such conditions, each generation of cleavage-forming white mica will retain its original growth age. In addition, rocks from metamorphic terranes can also contain populations of detrital and diagenetic white micas which also have distinct ages associated with them. A final complication, frequently found in these low-grade polymetamorphic samples is the presence of inseparable, intergrown chlorite and the problems with associated 39Ar recoil during irradiation of the samples, prior to sample analysis. The shapes of 40Ar/39Ar age spectra of white micas separated from such samples are frequently complex and are quite variable in shape. Some age spectra show a steady increase in age with increase in the temperature of release, while others have sigmoidal or saddle-shaped patterns. The age of most of the steps in such age spectra are mixtures of the various age populations of white mica in the sample, and as such are geologically meaningless. Nonetheless, useful constraints on the ages of at least some events recorded in these complex low-grade polymetamorphic rocks can be discerned with the help of petrographic observations, and by placing the results in a spatial context to test for reproducibility and/or the occurrence of meaningful patterns. If no chlorite is present and the sample contains no detrital white mica, an estimate of the maximum age of the youngest component and the minimum age of the oldest cleavage forming white mica populations can frequently be discerned. If the sample contains detrital white mica, a minimum age for its cooling or crystallization can be estimated. The presence of a small amount of intimately intergrown chlorite masks the age of the youngest white

    Due to their minute size, 40Ar/39Ar analysis of illite faces significant analytical challenges, including mineral characterization and, especially, effects of grain size and crystallography on 39Ar recoil. Quantifying the effects of 39Ar recoil requires the use of sample vacuum encapsulation during irradiation, which permits the measurement of the fraction of recoiled 39Ar as well as the 39Ar and 40Ar∗ retained within illite crystals that are released during step heating. Total-Gas Ages (TGA) are calculated by using both recoiled and retained argon, which is functionally equivalent to K-Ar ages, while Retention Ages (RA) only involve retained Ar in the crystal. Natural applications have shown that TGA fits stratigraphic constraints of geological processes when the average illite crystallite thickness (ICT) is smaller than 10 nm, and that RA matches these constraints for ICTs larger than 50 nm. We propose a new age correction method that takes into account the average ICT and corresponding recoiled 39Ar for a sample, with X-ray Corrected Ages (XCA) lying between Total-Gas and Retention Ages depending on ICT. This correction is particularly useful in samples containing authigenic illite formed in the anchizone, with typical ICT values between 10 and 50 nm. In three samples containing authigenic illite from Cretaceous carbonates in the Monterrey Salient in northern Mexico, there is a range in TGAs among the different size-fractions of 46-49, 36-43 and 40-52 Ma, while RAs range from 54-64, 47-52 and 53-54 Ma, respectively. XCA calculations produce tighter age ranges for these samples of 52.5-56, 45.5-48.5 and 49-52.5 Ma, respectively. In an apparent age vs ICT or %2M 1illite plot, authigenic illite grains show a slope that is in general slightly positive for TGA, slightly negative for RA, but close to zero for XCA, with thinner crystallites showing more dispersion than thicker ones. In order to test if dispersion is due to a different formation history or the result

    The aim of the study was to explore the patterns of dental health services access in children under twelve years of age in Peru. Data from 25,285 children under 12 years who participated in the Demographic and Family Health Survey of 2014 were reviewed. An exploratory spatial analysis was performed to project the proportions of children with access to dental health services, according to national regions, type of health service and urban or rural place of residence. The results show that of the total sample, 26.7% had access to dental health services in the last six months, 39.6% belonged to the age group 0-4 years, 40.6% lived in the Andean region and 58.3% lived in urban areas. The regions of Huancavelica, Apurimac, Ayacucho, Lima and Pasco had the highest percentages of access nationwide. In conclusion, there is low access to dental health services in the population under 12 years of age in Peru. The spatial distribution of access to dental health services allows regions to be identified and grouped according to similar access patterns, in order to better focus public health actions.

    Sugar-sweetened beverages (SSBs) have been associated with obesity in children and adults; however, associations between beverage patterns and obesity are not understood. Our aim was to describe beverage patterns during adolescence and associations between adolescent beverage patterns and anthropometric measures at age 17 years. We conducted a cross-sectional analyses of longitudinally collected data. Data from participants in the longitudinal Iowa Fluoride Study having at least one beverage questionnaire completed between ages 13.0 and 14.0 years, having a second questionnaire completed between 16.0 and 17.0 years, and attending clinic examination for weight and height measurements at age 17 years (n=369) were included. Beverages were collapsed into four categories (ie, 100% juice, milk, water and other sugar-free beverages, and SSBs) for the purpose of clustering. Five beverage clusters were identified from standardized age 13 to 17 years mean daily beverage intakes and named by the authors for the dominant beverage: juice, milk, water/sugar-free beverages, neutral, and SSB. Weight, height, and body mass index (BMI; calculated as kg/m 2 ) at age 17 years were analyzed. We used Ward's method for clustering of beverage variables, one-way analysis of variance and χ 2 tests for bivariable associations, and γ-regression for associations of weight or BMI (outcomes) with beverage clusters and demographic variables. Linear regression was used for associations of height (outcome) with beverage clusters and demographic variables. Participants with family incomes <$60,000 trended shorter (1.5±0.8 cm; P=0.070) and were heavier (2.0±0.7 BMI units; P=0.002) than participants with family incomes ≥$60,000/year. Adjusted mean weight, height, and BMI estimates differed by beverage cluster membership. For example, on average, male and female members of the neutral cluster were 4.5 cm (P=0.010) and 4.2 cm (P=0.034) shorter, respectively, than members of the milk cluster. For

    We measured optical and biometric parameters of emmetropic eyes as a function of age. There were approximately 20 subjects each in age groups 18-29, 30-39, 40-49, 50-59, and 60-69 years with similar male and female numbers. One eye was tested for each subject, having spherical equivalent in the range -0.88 D to +0.75 D and age changes: anterior chamber depth decreased 0.011 mm/year, lens central thickness increased 0.024 mm/year, anterior segment depth increased 0.013 mm/year, eye length increased 0.011 mm/year, anterior lens radius of curvature decreased 0.044 mm/year, and lens equivalent refractive index decreased 0.0003/year. Males had higher anterior corneal radii of curvature (0.16 mm), lower lens equivalent refractive index (0.006), longer vitreous lengths (0.51 mm), and longer axial lengths (0.62 mm) than females. Superficially, the results suggest that eyes get bigger as they age. However, results can be related to refraction patterns in which refraction is stable in 20s to 40s and then moves in the hypermetropic direction. It is likely that several young subjects will become hypermetropic as they age, and it is possible that some of the older subjects were myopic when younger.

    The nature and timing of metamorphic events in the Coastal Lithotectonic Block of Maine remain poorly understood. Immediately west and southwest of Penobscot Bay the rocks are polymetamorphic showing evidence for at least two episodes of amphibolite facies metamorphism and later, perhaps regionally extensive, retrograde events. Hornblende mineral separates from two amphibolites din the Port Clyde area have identical Ar-40/Ar-39 plateau ages of 414.0 [+-] 3.3 and 414.0 [+-] 3.9 Ma. These ages are interpreted to reflect the time of cooling following the last significant thermal event in this area. Biotite from an amphibolite in the Port Clyde area givesmore » a total gas age of 346.5 [+-] 3.2 Ma. Hornblende from an amphibolite 7 km to the west near Friendship gives a nearly concordant release spectrum with a plateau age of 369.0 [+-] 3.7 Ma. Coexisting biotite from this amphibolite gives a total gas age of 289.2 [+-] 2.7 Ma. Muscovite from the Waldoboro pluton has a nearly concordant release spectrum with a plateau age of 306.3 [+-] 2.2 Ma. Biotite from this sample gives a total gas age of 288.9 [+-] 2.2 Ma. The 414.0 Ma hornblende cooling ages from the Port Clyde area reflect cooling following a significant high grade Silurian thermal event. This Silurian metamorphism is the same age as tectonothermal events in the Nashoba Terrane in eastern Massachusetts, the Kingston Complex in southern New Brunswick, the Aspy Terrane in Cape Breton island, Nova Scotia, and the Hermitage Flexure in southern Newfoundland.d Thus a distinctive Silurian tectonothermal province located along the western edge of the Avalon Zone appears to extend discontinuously from Massachusetts to Newfoundland.« less

    We have retrospectively examined the nature of acute mastioditis (in western Norway) during a 20 year period (1980-2000). Sixty-one cases of AM were identified in 57 patients with a mean age of 3.6 years. We found no significant change in the incidence of AM during the last 20 years. Seven patients were treated solely with intravenous antibiotics and myringotomies. Fifty patients also underwent cortical mastoidectomy, four cases with bilateral surgery. Antibiotic treatment was given to 31 of the patients before admission to hospital and this group had a significant longer duration of symptoms (12.4 days) compared to untreated patients (7.3 days). Streptococcus pneumoniae was the most common organism recovered from patient cultures. Surgery was found to correlate to patients with retroauricular fluctuation or to children with at least two of the three clinical signs: protrusion of the ear, retroauricular oedema and swelling of the ear canal. Our data show that clinical examination only reveal 50% of the cases with surgically proven retroauricular subperiostal abscess. We therefore recommend a CT scan of patients treated conservatively.

    Hizentra® (IGSC 20%) is a 20% liquid IgG product approved for subcutaneous administration in adults and children 2 years of age and older who have primary immunodeficiency disease (PIDD). There is limited information about the use of IGSC 20 % in very young children including those less than 5 years of age. A retrospective chart review involved 88 PIDD infants and children less than 5 years of age who received Hizentra®. The mean age at the start of Hizentra® was 34 months (range 2 to 59 months). IGSC 20 % was administered weekly to 86 infants (two additional infants received twice weekly and three times weekly infusions, respectively) and included an average of 63 infusions (range 6-182) for an observation period up to 45.5 months. Infusion by manual delivery occurred in 15 patients. The mean dose was 674 mg/kg/4 weeks. The mean IgG level was 942 mg/dL while on IGSC 20 %, compared to a mean trough IgG level of 794 mg/dL (p < 0.0001) during intravenous or subcutaneous IgG administration prior to IGSC 20 %. Average infusion time was 47 (range 5-120) minutes, and the median number of infusion sites was 2 (range 1-4). Local reactions were mostly mild and observed in 36/88 (41%) children. No serious adverse events were reported. A significant increase in weight percentile (7 % ± 19.2, p = 0.0012) among subjects was observed during IGSC 20% administration. The rate of serious bacterial infections was 0.067 per patient-year while receiving IGSC 20%, similar to previously reported efficacy studies. Hizentra® is effective in preventing infections, and is well tolerated in children less than age 5 years.

    Major changes happened in the last decade in the HIV/AIDS pandemic. The disease is no longer limited to young age. Due to the effectiveness of HAART (Highly Active Anti-Retroviral Therapy) as well as new diagnosis in older age groups, many patients in AIDS centers are above 50 years of age. To determine the prevalence, demographics and clinical characteristics of newly diagnosed HIV/AIDS patients older than 50 years compared to younger newly diagnosed patients. Retrospective single center analysis of the demographics and clinical characterizations of 62 newly diagnosed HIV/AIDS patients over 50 years of age. The average age at diagnosis of the whole cohort was 39+/-16 years. There was a gradual increase in the age at diagnosis over the years, as well as the percent of patients above the age of 50 diagnosed with the disease. In comparison to younger patients, in the older group there were more males compared to females and less patients who acquired the HIV/AIDS in unprotected homosexual sex. Furthermore, CD4 cells counts were lower and viral load leveLs were higher at diagnosis in the older group. Despite good adherence, patients above the age of 50 don't achieve adequate immunological response and many are left with significant immunodeficiency (CD4<200). The prevaLence of patients above the age of 50 Living with HIV/AIDS in Israel is rising. Programs aimed at prevention, education and screening for this unique group are mandatory. An AIDS center should adopt new programs and routines to cope with the increasing number of patients over the age of 50 Living with HIV/AIDS.

    Migraines in children younger than 7 years of age have received limited attention in the published literature. The aim of this study is to describe the characteristics of migraine phenotypes in children younger than 7 years, and to compare them with migraines in children older than 7 years of age. We reviewed all standard clinical files, collected over 4 years, related to children with a diagnosis of primary headache. We included all children younger than 7 years diagnosed with migraine in our study. A total of 374 children (188 males, 186 females) were affected by migraine with/without aura: 40 of these patients (10.7%; 20 males, 20 females; mean age 5y 7mo, SD 1y 2mo) where younger than 7 years old. The frequencies of the main migraine features in the younger age group were similar to those of children older than 7 years, with the exception of a shorter duration of migraine and reduced frequency of attacks. In children younger than 7 years of age, the clinical phenotype of migraine is similar to that seen in older children. We propose that there is a general genetic migraine susceptibility that, in the presence of activating environmental factors, may induce typical attacks of migraine in individuals already predisposed to migraine attacks. Therefore, different modules induce different clinical features within the different age groups, but there is no difference in the frequencies of clinical phenotypes between the two age groups. © 2015 Mac Keith Press.

  4. The single grain fusion dating approach: Determining the factors that control white mica 40Ar/39Ar age formation during HP metamorphism of the Cycladic Blueschist Unit, Greece

    White mica 40Ar/39Ar dating is a proven powerful tool for constraining the timing and rate of metamorphism, deformation and exhumation. However, for high-pressure metamorphic rocks dating often results in wide age ranges, which are not in agreement with constraints from other isotopic systems, indicating that geological and chemical processes complicate straightforward 40Ar/39Ar dating. Despite hosting one of the largest geochronological datasets in the world, the Cycladic Blueschist Unit in Greece is presently one of the focal areas in the discussion on the interpretation of metamorphic 40Ar/39Ar ages. Previous phengite multi grain step heating experiments commonly yielded undulating age spectra ranging between 20 - 60 Ma. While some studies attempt to assign geological significance to these ages, others argue the ages are geologically meaningless and the result of the interplay between partial diffusive resetting and continued crystallization. By taking an alternative approach of multiple single grain fusion experiments, this study investigates age heterogeneity between samples of contrasting metamorphic facies, rheology and strain from the Cycladic islands of Syros and Sifnos. Comparing the size and shape of single grain fusion age distributions at the grain, rock, outcrop and island scale allows determination of the scale at which different age-forming processes operate. Resulting ages show a previously unreported consistent variation between different outcrops, moving from the eclogite-blueschist facies (55-45 Ma) to greenschist overprinting (40-30 Ma). This indicates that outcrop scale homogeneous resetting is the dominant processes for age formation in the CBU. Single grain age variation at the sample and outcrop scale is only limited to 10 Ma, indicating a smaller but observable role for local age perturbing processes of incomplete resetting, continued (re)crystallization or infiltration of excess argon. Some of the partially overprinted samples show

    Objective To examine the self-perceived health of very low birth weight (VLBW; <1.5 kg) infants during young adulthood. Study design The population included 241 VLBW and 232 normal birth weight (NBW) controls who completed the Child Health and Illness Profile: Adolescent Edition (CHIP-AE) at 20 years of age. The CHIP-AE includes six domains: Satisfaction, Comfort, Resilience, Achievement, Risk Avoidance, and Disorders, and 13 profiles that characterize patterns of health. Results were compared between VLBW and NBW subjects adjusting for sex and sociodemographic status. Results VLBW subjects did not differ from NBW controls in the domains of Satisfaction or Comfort but reported less Resilience (effect size [ES] −0.19, P < .05), specifically in physical activity and family involvement. They reported better Achievement, specifically in work performance (ES 0.28, P < .05), more Risk Avoidance (ES 0.43, P < .001), and significantly more long-term medical, surgical, and psychosocial disorders. Similar proportions of VLBW and NBW subjects reported Excellent (15% vs 11%), Average (27% vs 34%), and Poor (12% vs 13%) profiles of health. Conclusions VLBW subjects report similar health, well-being, and functioning compared with NBW controls and greater risk avoidance. However, we are concerned that their lesser resilience may prove detrimental to their future adult health. PMID:18035144

    The present study addresses critical gaps in the literature by examining residential transitions among 303 adults with intellectual disability over 10 years (Part 1) and 75 adults with Down syndrome over 20 years (Part 2). All adults lived at home at the start of the study, but many moved to a variety of settings. Several characteristics of the adults with intellectual disability differed across settings, most notably adaptive behavior and the number of residential transitions, while characteristics such as age, type of disability, and behavior problems were less predictive of residential placements. The number of moves over the course of the study varied widely, with critical links to earlier family dynamics, social relationships, and health and adaptive behavior. PMID:25354121

    The study characterized the oral health condition and main self-reported reasons for tooth extraction in an adult population. The cross-sectional study examined 248 adults aged 20-64 years, representative of the population of Piracicaba, São Paulo, Brazil. The oral examination conducted in households used the DMFT and CPI indexes, use and necessity of prosthodontics according to the WHO criteria and the presence of visible biofilm. Demographic and socioeconomic data were collected along with reasons for tooth extraction through a questionnaire. Descriptive analysis was stratified by age in groups: 20-44 and 45-64 years old. The average DMFT was 20.37 (EP = 0.50), P = 3.34 (EP = 0.33) for young adults and P = 13.41 (EP = 1.45) for the older adults. Gingival pockets (CPI ≥ 3) were found on 20.5% of young adults and 53.0% of the older ones. While 38.8% used upper prosthesis, 46.7% needed lower prosthesis. Pain was the most prevalent self-reported reason for tooth extraction (37.5%), being this choice primarily because of lack of another treatment option (52%) and done in the private sector (47.2%). We concluded that young adults (20-44 years old) showed less missing teeth, periodontal diseases, and need for prosthetic use. Pain and lack of options of other treatments were the main self-reported reasons for performing tooth extractions.

    To examine the epidemiology of young women screened for gonorrhoea in the USA. Data on tests for gonorrhoea among women aged 15-24 years attending family planning clinics from 2005 to 2007 were obtained through the infertility prevention project. Clinics testing 90% or more of women for gonorrhoea and sending 50 or more gonorrhoea tests per year were included. Gonorrhoea positivity on a state and county level was calculated and compared by age and race/ethnicity. A total of 1,119,394 tests from 948 clinics was eligible for inclusion. Median state-specific gonorrhoea positivity was 1.3% (IQR 0.7-2.0%). Positivity was higher among women aged 15-19 years (1.4%, IQR 0.9-2.6%) than among those aged 20-24 years (1.1%, IQR 0.6-1.4%, p=0.03) and among non-Hispanic black women (3.8%, IQR 3.2-4.6%) than non-Hispanic white women (0.6%, IQR 0.4-0.8%, p<0.0001). Half of all gonorrhoea cases in these women originated from 57 of 753 counties. Among non-Hispanic white women, positivity was 2.0% or greater in 4% of counties, while 83% of counties had gonorrhoea positivity of less than 1.0%. Gonorrhoea positivity among non-Hispanic black women was 2.0% or greater in 58% of counties, and less than 1.0% in only one-third of counties. These disparities were present diffusely across the geographical areas included in this analysis. Gonorrhea positivity was consistently high for young non-Hispanic black women attending family planning clinics across multiple geographical regions. A large proportion of gonorrhoea morbidity was concentrated in a relatively small number of counties in the USA among this population of young women.

    The aim of this study is to compare the oral hygiene status among institutionalized visually impaired children of age between 6 and 20 years given with Braille and audio instructions in Raichur city of Karnataka. A total of 50 children aged between 6 to 20 years were included in this study from a residential school for visually impaired children. These children were randomly divided into two equal groups. One group was given oral hygiene instructions by audio recordings and another written in Braille and were instructed to practice the same. After three months time the oral hygiene status and dental caries experience was recorded and compared using patient performance index. Statistical analysis was done by student paired t test and multiple comparison by Tukey's HSD (honest significant difference) test. The mean PHP (Patient Hygiene Performance) score of group A at baseline was 3.88 compared to 3.90 of group B. At 7 days PHP score of group A and group B was 3.42 and 3.45 respectively. At 3 month PHP score of group A and group B was 2.47 and 2.86 respectively. Even though over a period of time the mean score of PHP index reduced the score comparison between the 2 groups were statistically non significant. In group A the mean difference of PHP score between baseline and 7 days was 0.46, between baseline and 3 months it was 1.40. The PHP score between 7 days and 3 months was 0.94. All the above values were statistically significant. Effective dental health education method has to be instituted for visually impaired children. The present study shows improvement of oral health status in both the study population by decrease in the mean plaque score. Hence continuous motivation and reinforcement in the form of Braille and audio instruction is beneficial to achieve good oral hygiene levels in visually impaired children.

    Confidence in 3D multi-segment foot models has been limited by a lack of repeatability data, particularly in older populations that may display unique functional foot characteristics. This study aimed to determine the intra and inter-observer repeatability of stance phase kinematic data from a multi-segment foot model described by Leardini et al. [2] in people aged 50 years or older. Twenty healthy adults participated (mean age 65.4 years SD 8.4). A repeated measures study design was used with data collected from four testing sessions on two days from two observers. Intra (within-day and between-day) and inter-observer coefficient of multiple correlations revealed moderate to excellent similarity of stance phase joint range of motion (0.621-0.975). Relative to the joint range of motion (ROM), mean differences (MD) between sessions were highest for the within-day comparison for all planar ROM at the metatarsus-midfoot articulation (sagittal plane ROM 5.2° vs. 3.9°, MD 3.1°; coronal plane ROM 3.9 vs. 3.1°, MD 2.3°; transverse plane ROM 6.8° vs. 5.16°, MD 3.5°). Consequently, data from the metatarsus-midfoot articulation in the Istituto Ortopedico Rizzoli (IOR) foot model in adults aged over 50 years needs to be considered with respect to the findings of this study.

  2. 40Ar/39Ar ages for the fossil-bearing Gyeongsang Supergroup in South Korea

    2016-12-01

    Since the 1970s, abundant vertebrate fossils have been documented from the Cretaceous Gyeongsang Supergroup in the Gyeongsang Basin and some small nearby basins of the Korean Peninsula, including dinosaurs, pterosaurs, crocodilians, turtles and fish. In addition to body fossils, well-preserved dinosaur, bird and pterosaur tracks have been found from these formations. Well-preserved and extensive vertebrate ichnofaunas from the Gyeongsang Supergroup represent the largest known concentration of Cretaceous vertebrate track sites reported from the Asian continent. Determining the age of the Gyeongsang Supergroup is critical to understanding several fundamental questions related to evolution and paleo-biogeography. However, limited radioisotopic studies for the Gyeongsang Supergroup have been previously reported. Additionally, the large uncertainties of previous data and the incomplete stratigraphic description of the samples limit their value for high-resolution chronostratigraphy. In this study, we aim to establish high-precision 40Ar/39Ar ages for two well-known tuffs from the middle and the upper part of the Gyeongsang Supergroup, and one rhyolite from the uppermost Gyeongsang Supergroup. Our preliminary 40Ar/39Ar data for the Kusandong Tuff indicates that the middle part of the Gyeongsang Supergroup is 78-82 Ma. This is consistent with the hypothesized extension of the Jehol biota into Korea and the preliminary results suggest that refinement of the time scale for these strata is a practical goal. The Gyeongsang Supergroup sample has great potential for substantially increasing our knowledge of Mesozoic terrestrial ecosystems.

    Aims To examine long-term changes in environmental tobacco smoke (ETS) exposure in British men between 1978 and 2000, using serum cotinine. Design Prospective cohort: British Regional Heart Study. Setting General practices in 24 towns in England, Wales and Scotland. Participants Non-smoking men: 2125 studied at baseline [questionnaire (Q1): 1978–80, aged 40–59 years], 3046 studied 20 years later (Q20: 1998–2000, aged 60–79 years) and 1208 studied at both times. Non-smokers were men reporting no current smoking with cotinine < 15 ng/ml at Q1 and/or Q20. Measurements Serum cotinine to assess ETS exposure. Findings In cross-sectional analysis, geometric mean cotinine level declined from 1.36 ng/ml [95% confidence interval (CI): 1.31, 1.42] at Q1 to 0.19 ng/ml (95% CI: 0.18, 0.19) at Q20. The prevalence of cotinine levels ≤ 0.7 ng/ml [associated with low coronary heart disease (CHD) risk] rose from 27.1% at Q1 to 83.3% at Q20. Manual social class and northern region of residence were associated with higher mean cotinine levels both at Q1 and Q20; older age was associated with lower cotinine level at Q20 only. Among 1208 persistent non-smokers, cotinine fell by 1.47 ng/ml (95% CI: 1.37, 1.57), 86% decline. Absolute falls in cotinine were greater in manual occupational groups, in the Midlands and Scotland compared to southern England, although percentage decline was very similar across groups. Conclusions A marked decline in ETS exposure occurred in Britain between 1978 and 2000, which is likely to have reduced ETS-related disease risks appreciably before the introduction of legislation banning smoking in public places.

  9. Lung Cancer Risk and Demographic Characteristics of Current 20-29 Pack-year Smokers: Implications for Screening.

    PubMed

    2015-11-01

    Based on current recommendations, 30+ pack-years of smoking are required for eligibility for low-dose CT (LDCT) lung cancer screening; former smokers must have quit within 15 years. We investigated whether current smokers with 20 to 29 pack-years have similar lung cancer risks as eligible former smokers and also whether they have a different demographic profile. The Prostate, Lung, Colorectal, and Ovarian Cancer Screening Trial (PLCO) was a randomly assigned screening trial of subjects age 55 to 74 years with chest radiographs (CXR) used for lung cancer. Subjects completed a baseline questionnaire containing smoking history questions. Cox proportional hazards models, adjusted for age and sex, were utilized to estimate hazard ratios (HRs) for various smoking history groups. Next, we utilized the National Health Interview Survey (NHIS), which inquired about smoking history and race/ethnicity, to analyze the demographic profiles of various high-risk smoking history categories. All statistical tests were two-sided. The PLCO cohort included 18 114 former and 12 243 current LDCT-eligible smokers, plus 2283 20- to 29-pack-year current smokers. The hazard ratio for 20- to 29-pack-year current smokers compared with eligible (30+ pack-year) former smokers was 1.07 (95% confidence interval [CI] = 0.75 to 1.5). Based on the NHIS, 10 million persons in the United States are currently LDCT eligible; an additional 1.6 million (16%, 95% CI = 13.6% to 19.0%) are 20- to 29-pack-year current smokers. The percentage increase in eligibles if 20- to 29-pack-year current smokers were included was substantially greater for women than men (22.2%, 95% CI = 17.9% to 26.7%; vs 12.2%, 95% CI = 9.3% to 15.3%, P < .001) and for minorities than non-Hispanic whites (30.0%, 95% CI = 24.2% to 36.0%; vs 14.1%, 95% CI = 11.1% to 17.0%, P < .001). The potential benefits and harms of recommending LDCT screening for 20 to 29-pack-year current smokers should be assessed. Published by Oxford University

  10. Preservation of ancient impact ages on the R chondrite parent body: 40Ar/39Ar age of hornblende-bearing R chondrite LAP 04840

    USGS Publications Warehouse

    Righter, Kevin; Cosca, Michael A.; Morgan, Leah

    2016-01-01

    The hornblende- and biotite-bearing R chondrite LAP 04840 is a rare kind of meteorite possibly containing outer solar system water stored during metamorphism or postshock annealing deep within an asteroid. Because little is known regarding its age and origin, we determined 40Ar/39Ar ages on hornblende-rich separates of the meteorite, and obtained plateau ages of 4340(±40) to 4380(±30) Ma. These well-defined plateau ages, coupled with evidence for postshock annealing, indicate this meteorite records an ancient shock event and subsequent annealing. The age of 4340–4380 Ma (or 4.34–4.38 Ga) for this and other previously dated R chondrites is much older than most impact events recorded by ordinary chondrites and points to an ancient event or events that predated the late heavy bombardment that is recorded in so many meteorites and lunar samples.

    Most of the published papers on Rheumatic Fever (RF) have not included the younger population. We selected 211 cases of children with RF younger than 6 years of age from 9,471 clinical files from 1944 to 1982. These were followed retrospectively to identify the presence of rheumatic activity, subsequent attacks and penicillin profilaxis. From de 211 cases, 209 had carditis; 57% of them were girls and 43% boys. There were no previous infections of the upper respiratory tract in 36% of the patients. The number of cases with RF increased abruptly after 3 years of age and continued increasing until 5 years of age when 70.5% of the population had there first clinically recognized attack. Lesions were present in the mitral valve in 80% of the cases, in the aortic valve in 12%, in the tricuspid in 5% and in the pulmonary valve in 3%. The death rate during the first attack was 20% being refractory heart failure the main cause of death. Thirteen cases suffered rheumatic pneumonia, 9 of whom died (69.2%). 1) The incidence of acute rheumatic fever in children under 6 years of age has decreased with time. 2) The death rate as well as the valvular damage decreased with the parents cooperation with the treatment. 3) The changes in the clinical picture and the severity of valve sequelea may be due to penicillin profilaxis and the better understanding of the disease.

    A higher operative mortality rate has been reported after redo valvular procedures than after the primary operation. Outcomes of 330 consecutive patients undergoing 433 redo valvular operations at our institute during a 20-year period (January 1990 to December 2010) were reviewed retrospectively. The mean follow-up was 6.4 years (range, 0.05 to 1.3 years). Logistic regression analysis was used to identify factors associated with hospital death. The overall hospital mortality rate was 6.7% (29 of 433 procedures). Logistic regression analysis identified only advanced New York Heart Association (NYHA) class as an independent predictor of hospital death. Overall survival at 5, 10, and 15 years was 83.6%±2.2%, 70.7%±3.4%, and 61.5%±4.5%, respectively. The 5-, 10-, and 15-year survivals for the first redo vs more than second redo groups were 86.5%±2.4% vs 74.7%±5.5%, 71.8%±3.9% vs 66.8%±6.6%, and 60.2%±5.7% vs 63.1%±7.2%, respectively (log-rank P=0.505). The 5- and 10-year survivals for NYHA class I/II vs III/IV patients were 91.5%±2.1% vs 70.4%±4.5% and 77.8%±4.1% vs 58.5%±5.6%, respectively (log-rank p<0.005). Redo valvular operation in NYHA class III/IV patients is associated with high hospital death and poor long-term survival. To achieve low hospital death and good long-term survival, redo operations, including more than third redo operations, should be performed in patients with lower NYHA class.

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

    Accurate understanding of the subsurface production rate of the radionuclide 39Ar is necessary for argon dating techniques and noble gas geochemistry of the shallow and the deep Earth, and is also of interest to the WIMP dark matter experimental particle physics community. Our new calculations of subsurface production of neutrons, 21Ne , and 39Ar take advantage of the state-of-the-art reliable tools of nuclear physics to obtain reaction cross sections and spectra (TALYS) and to evaluate neutron propagation in rock (MCNP6). We discuss our method and results in relation to previous studies and show the relative importance of various neutron, 21Ne , and 39Ar nucleogenic production channels. Uncertainty in nuclear reaction cross sections, which is the major contributor to overall calculation uncertainty, is estimated from variability in existing experimental and library data. Depending on selected rock composition, on the order of 107-1010 α particles are produced in one kilogram of rock per year (order of 1-103 kg-1 s-1); the number of produced neutrons is lower by ∼ 6 orders of magnitude, 21Ne production rate drops by an additional factor of 15-20, and another one order of magnitude or more is dropped in production of 39Ar. Our calculation yields a nucleogenic 21Ne /4He production ratio of (4.6 ± 0.6) ×10-8 in Continental Crust and (4.2 ± 0.5) ×10-8 in Oceanic Crust and Depleted Mantle. Calculated 39Ar production rates span a great range from 29 ± 9 atoms kg-rock-1 yr-1 in the K-Th-U-enriched Upper Continental Crust to (2.6 ± 0.8) × 10-4 atoms kg-rock-1 yr-1 in Depleted Upper Mantle. Nucleogenic 39Ar production exceeds the cosmogenic production below ∼700 m depth and thus, affects radiometric ages of groundwater. The 39Ar chronometer, which fills in a gap between 3H and 14C , is particularly important given the need to tap deep reservoirs of ancient drinking water.

    OBJECTIVE: To investigate the association of dietary pattern and mortality in international data. DESIGN: Cohort study with 20 years' follow up of mortality. SETTING: Five cohorts in Finland, the Netherlands, and Italy. SUBJECTS: Population based random sample of 3045 men aged 50-70 years in 1970. MAIN OUTCOME MEASURES: Food intake was estimated using a cross check dietary history. In this dietary survey method, the usual food consumption pattern in the 6-12 months is estimated. A healthy diet indicator was calculated for the dietary pattern, using the World Health Organisation's guidelines for the prevention of chronic diseases. Vital status was verified after 20 years of follow up, and death rates were calculated. RESULTS: Dietary intake varied greatly in 1970 between the three countries. In Finland and the Netherlands the intake of saturated fatty acids and cholesterol was high and the intake of alcohol was low; in Italy the opposite was observed. In total 1796 men (59%) died during 20 years of follow up. The healthy diet indicator was inversely associated with mortality (P for trend < 0.05). After adjustment for age, smoking, and alcohol consumption, the relative risk in the group with the healthiest diet indicator compared with the group with the least healthy was 0.87 (95% confidence interval 0.77 to 0.98). Estimated relative risks were essentially similar within each country. CONCLUSIONS: Dietary intake of men aged 50-70 is associated with a 20 year, all cause mortality in different cultures. The healthy diet indicator is useful in evaluating the relation of mortality to dietary patterns. PMID:9233319

    To examine dementia characteristics, age at onset and associated co-morbidities in persons with Down syndrome. A total of 77 people with Down syndrome aged 35 years and older were followed up from 1996 to 2015. The diagnosis of dementia was established using the modified ICD 10 Criteria and a combination of objective and informant-based tests. Cognitive tests included the Test for Severe Impairment and the Down Syndrome Mental Status Examination; adaptive behaviour was measured using the Daily Living Skills Questionnaire, and data from the Dementia Questionnaire for People with Intellectual Disabilities have been available since 2005. Over the 20-year period, 97.4% (75 of 77) persons developed dementia with a mean age of dementia diagnosis of 55 years (SD = 7.1, median = 56 years). Clinical dementia was associated with cognitive and function decline and seizure activity. Risk for dementia increased from 23% in those aged 50 years to 80% in those aged 65 years and above. There were no differences by level of ID. The previously reported high risk levels for dementia among people with Down syndrome were confirmed in this data as was the relationship with late onset epilepsy. The value of the instruments utilised in tracking decline and helping to confirm diagnosis is further highlighted. © 2017 MENCAP and International Association of the Scientific Study of Intellectual and Developmental Disabilities and John Wiley & Sons Ltd.

    Pacific Northwest National Laboratory reports on the detection of 39 Ar at the location of an underground nuclear explosion on the Nevada Nuclear Security Site. The presence of 39 Ar was not anticipated at the outset of the experimental campaign but results from this work demonstrated that it is present, along with 37 Ar and 85 Kr in the subsurface at the site of an underground nuclear explosion. Our analysis showed that by using state-of-the-art technology optimized for radioargon measurements, it was difficult to distinguish 39 Ar from the fission product 85 Kr. Proportional counters are currently used for high-sensitivity measurement of 37 Ar and 39 Ar. Physical and chemical separation processes are used to separate argon from air or soil gas, yielding pure argon with contaminant gases reduced to the parts-per-million level or below. However, even with purification at these levels, the beta decay signature of 85 Kr can be mistaken for that of 39 Ar, and the presence of either isotope increases the measurement background level for the measurement of 37 Ar. Measured values for the 39 Ar measured at the site ranged from 36,000 milli- Becquerel/standard-cubic-meter-of-air (mBq/SCM) for shallow bore holes to 997,000 mBq/SCM from the rubble chimney from the underground nuclear explosion.

    A binocular approach to treating anisometropic and strabismic amblyopia has recently been advocated. Initial studies have yielded promising results, suggesting that a larger randomized clinical trial is warranted. To compare visual acuity (VA) improvement in children with amblyopia treated with a binocular iPad game vs part-time patching. A multicenter, noninferiority randomized clinical trial was conducted in community and institutional practices from September 16, 2014, to August 28, 2015. Participants included 385 children aged 5 years to younger than 13 years with amblyopia (20/40 to 20/200, mean 20/63) resulting from strabismus, anisometropia, or both. Participants were randomly assigned to either 16 weeks of a binocular iPad game prescribed for 1 hour a day (190 participants; binocular group) or patching of the fellow eye prescribed for 2 hours a day (195 participants; patching group). Study follow-up visits were scheduled at 4, 8, 12, and 16 weeks. A modified intent-to-treat analysis was performed on participants who completed the 16-week trial. Binocular iPad game or patching of the fellow eye. Change in amblyopic-eye VA from baseline to 16 weeks. Of the 385 participants, 187 were female (48.6%); mean (SD) age was 8.5 (1.9) years. At 16 weeks, mean amblyopic-eye VA improved 1.05 lines (2-sided 95% CI, 0.85-1.24 lines) in the binocular group and 1.35 lines (2-sided 95% CI, 1.17-1.54 lines) in the patching group, with an adjusted treatment group difference of 0.31 lines favoring patching (upper limit of the 1-sided 95% CI, 0.53 lines). This upper limit exceeded the prespecified noninferiority limit of 0.5 lines. Only 39 of the 176 participants (22.2%) randomized to the binocular game and with log file data available performed more than 75% of the prescribed treatment (median, 46%; interquartile range, 20%-72%). In younger participants (aged 5 to <7 years) without prior amblyopia treatment, amblyopic-eye VA improved by a mean (SD) of 2.5 (1.5) lines in the

    To describe the epidemiology of iron, zinc and iodide deficiencies in a probabilistic sample of Mexican women and children and explore its association with some dietary and socio-demographic variables. We carried out in 1999 an epidemiological description of iron (percent transferrin saturation, PTS, < 16%), serum zinc (< 65 ug/dl) and iodide (< 50 ug/l urine) deficiencies in a probabilistic sample of 1,363 Mexican children under 12 years and of 731 women of child-bearing age. Serum iron, Total Iron Binding Capacity (TIBC) and zinc were measured by atomic absorption spectrometry, and urinary iodide by a colorimetric method. Logistic regression models explored determinants for such micromineral deficiencies. Iron deficiency was higher (67%) in infants < 2 years of age. Prevalence declined (34-39%) at school age. The prevalence for iron deficiency in women was 40%. Zinc deficiency was higher in infants < 2 years of age (34%) than in school-age children (19-24%). Prevalence in women was 30%, with no rural/urban difference. In women the likelihood of iron deficiency decreased as SEL improved (p = 0.04) and increased with the intake of cereals (p = 0.01). The likelihood of low serum zinc levels was greater in women and children of low socioeconomic level (SEL) (p < 0.02 and p = 0.001) iodide deficiency was negligible in both children and women. The data shows high prevalence of iron deficiency-specially in infants 12 to 24 months of age. It is suggested that in older children and women 12 to 49 years of age that iron bioavailability is low. The prevalence of zinc deficiency was also very high. The English version of this paper is available too at: http://www.insp.mx/salud/index.html.

    To test the association of age (adolescents vs. older women) and place of delivery with receipt of immediate postpartum contraception in Mexico. Retrospective cohort study, Mexico, nationally representative sample of women 12-39years old at last delivery. We used multivariable logistic regression to test the association of self-reported receipt of postpartum contraception prior to discharge with age and place of delivery (public, employment based, private, or out of facility). We included individual and household-level confounders and calculated relative and absolute multivariable estimates of association. Our analytic sample included 7022 women (population, N=9,881,470). Twenty percent of the population was 12-19years old at last birth, 55% aged 20-29 and 25% 30-39years old. Overall, 43% of women reported no postpartum contraceptive method. Age was not significantly associated with receipt of a method, controlling for covariates. Women delivering in public facilities had lower odds of receipt of a method (Odds Ratio=0.52; 95% Confidence Interval (CI)=0.40-0.68) compared with employment-based insurance facilities. We estimated 76% (95% CI=74-78%) of adolescents (12-19years) who deliver in employment-based insurance facilities leave with a method compared with 59% (95% CI=56-62%) who deliver in public facilities. Both adolescents and women ages 20-39 receive postpartum contraception, but nearly half of all women receive no method. Place of delivery is correlated with receipt of postpartum contraception, with lower rates in the public sector. Lessons learned from Mexico are relevant to other countries seeking to improve adolescent health through reducing unintended pregnancy. Adolescents receive postpartum contraception as often as older women in Mexico, but half of all women receive no method. Copyright © 2016 The Authors. Published by Elsevier Inc. All rights reserved.

  4. 50 Years of Cognitive Aging Theory.

    2017-01-01

    The objectives of this Introduction to the Journal of Gerontology: Psychological Sciences special issue on "50 Years of Cognitive Aging Theory" are to provide a brief overview of cognitive aging research prior to 1965 and to highlight significant developments in cognitive aging theory over the last 50 years. Historical and recent theories of cognitive aging were reviewed, with a particular focus on those not directly covered by the articles included in this special issue. Prior to 1965, cognitive aging research was predominantly descriptive, identifying what aspects of intellectual functioning are affected in older compared with younger adults. Since the mid-1960s, there has been an increasing interest in how and why specific components of cognitive domains are differentially affected in aging and a growing focus on cognitive aging neuroscience. Significant advances have taken place in our theoretical understanding of how and why certain components of cognitive functioning are or are not affected by aging. We also know much more now than we did 50 years ago about the underlying neural mechanisms of these changes. The next 50 years undoubtedly will bring new theories, as well as new tools (e.g., neuroimaging advances, neuromodulation, and technology), that will further our understanding of cognitive aging. © The Author 2016.

    To assess the prevalence of type 2 diabetes mellitus (T2DM) and maturity onset diabetes of the young (MODY) in children and adolescents aged 0-20 yr in Baden-Württemberg (BW), Germany, and to compare our results with those from other European countries. Our study involved every children's hospital (n = 31), each diabetologist in private practice (n = 122), and every internal medicine unit (n = 164) in BW. A written questionnaire and a telephone survey were used to identify children with T2DM and MODY who had been examined at any of these institutions between 2004 and 2005. Population data were drawn from the national census of 1987 and the subsequent annual updates. The prevalence of T2DM for the age range from 0 to 20 yr is 2.30/100 000, whereas the prevalence of MODY in the same age range is 2.39/100 000. The median age of patients with T2DM was 15.8 yr, and 13.9 yr for MODY patients. The majority of patients with either T2DM or MODY were treated in children's hospitals and by consultant diabetologists. A molecular genetic analysis was done to substantiate the clinical diagnosis in less than half of the recruits (14.3% of T2DM and 44.8% of MODY patients). The prevalence of T2DM and MODY is considerably lower than the prevalence of type 1 diabetes. Type 2 diabetes thus continues to be a rare disease in children and adolescents in Germany, as is also the case in other European countries.

  6. Accuracy of Recalled Body Weight – A Study with 20-years of Follow-up

    2013-01-01

    Objective Weight changes may be an important indicator of an ongoing pathological process. Retrospective self-report might be the only possibility to capture prior weight. The objective of the study was to evaluate the accuracy of retrospective recall of body weight in old age and factors that might predict accuracy. Design and Methods In 2007, 646 participants (mean age, 71.6 years) of the Swedish Adoption/Twin Study of Aging (SATSA) answered questions about their present weight and how much they weighed 20-years ago. Of these, 436 had self-reported their weight twenty years earlier and among these 134 had also had their weight assessed at this time point. Results Twenty year retrospectively recalled weight underestimated the prior assessed weight by −1.89 ± 5.9 kg and underestimated prior self-reported weight by −0.55 ± 5.2 kg. Moreover, 82.4% of the sample were accurate within 10%, and 45.8% were accurate within 5% of their prior assessed weights; similarly, 84.2% and 58.0 % were accurate within 10% and 5% respectively, for prior self-reported weight. Current higher body mass index and preferences of reporting weights ending with zero or five was associated with an underestimation of prior weight, while greater weight change over 20 year, and low Mini-Mental State Scores (MMSE) (<25) led to an overestimation of prior weight. Conclusions Recalled weight comes close to the assessed population mean, but at the individual level there is a large variation. The accuracy is affected by current BMI, changes in weight, end-digit preferences, and current cognitive ability. Recalled weight should be used with caution. PMID:23913738

  7. A new high-precision 40Ar/39Ar age for the Rochechouart impact structure: At least 5 Ma older than the Triassic-Jurassic boundary

    The Rochechourt impact structure in south-central France, with maximum diameter of 40-50 km, has previously been dated to within 1% uncertainty of the Triassic-Jurassic boundary, at which time 30% of global genera became extinct. To evaluate the temporal relationship between the impact and the Triassic-Jurassic boundary at high precision, we have re-examined the structure's age using multicollector ARGUS-V 40Ar/39Ar mass spectrometry. Results from four aliquots of impact melt are highly reproducible, and yield an age of 206.92 ± 0.20/0.32 Ma (2σ, full analytical/external uncertainties). Thus, the Rochechouart impact structure predates the Triassic-Jurassic boundary by 5.6 ± 0.4 Ma and so is not temporally linked to the mass extinction. Rochechouart has formerly been proposed to be part of a multiple impact event, but when compared with new ages from the other purported "paired" structures, the results provide no evidence for synchronous impacts in the Late Triassic. The widespread Central Atlantic Magmatic Province flood basalts remain the most likely cause of the Triassic-Jurassic mass extinction.

    The relationship between age and asthma phenotypes is important as population is ageing, asthma is becoming common in older ages and recently developed treatments for asthma are guided by phenotypes. The aim of this study is to evaluate whether age is associated with specific asthma phenotypes. This is a cross-sectional study. We included subjects with asthma of varied degrees of severity. Subjects underwent spirometry, skin prick test to aeroallergens, answered the Asthma Control Questionnaire and had blood samples collected. We performed binary logistic regression analysis to evaluate whether age is associated with asthma phenotypes. We enrolled 868 subjects. In comparison with subjects ≤ 40 years, older subjects had high odds of irreversible airway obstruction (from 41 to 64 years, OR: 1.83 (95% CI: 1.32-2.54); ≥65 years, OR: 3.45 (2.12-5.60)) and severe asthma phenotypes (from 41 to 64 years, OR: 3.23 (2.26-4.62); ≥65 years, OR: 4.55 (2.39-8.67)). Older subjects had low odds of atopic (from 41 to 64 years, OR: 0.56 (0.39-0.79); ≥65 years, OR: 0.47 (0.27-0.84)) and eosinophilic phenotypes (from 41 to 64 years, OR: 0.63 (0.46-0.84); ≥65 years, OR: 0.39 (0.24-0.64)). Older subjects with asthma have low odds of atopic and eosinophilic phenotypes, whereas they present high odds of irreversible airway obstruction and severe asthma. © 2017 Asian Pacific Society of Respirology.

    Age has been suggested as a negative prognostic factor for hip arthroscopy. The purpose of this study was to compare patient characteristics and outcomes after hip arthroscopy in patients aged 50 years or older with a matched control group of patients aged 30 years or younger at a minimum postoperative follow-up of 2 years. Between September 2008 and March 2010, data were prospectively collected on all patients aged 50 years or older undergoing primary hip arthroscopy. Fifty-two patients met our inclusion and matching criteria, of whom all 52 (100%) were available for follow-up at a minimum of 2 years. This cohort was compared with a matched-pair control group of patients aged 30 years or younger who underwent similar procedures. The mean age of the study group was 54.8 years (range, 50 to 69 years), and that of the control group was 20.3 years (range, 13 to 30 years). The groups were matched at a 1:1 ratio, including 18 male patients (34.6%) and 34 female patients (65.4%) in each group, with a mean follow-up period of 32 months (range, 24 to 54 months). In the younger control group, the score improvement from preoperatively to 2 years' follow-up was 62.9 to 84.2 for the modified Harris Hip Score, 60.5 to 84.2 for the Non-Arthritic Hip Score, 63.1 to 86.5 for the Hip Outcome Score-Activities of Daily Living, and 42.2 to 72.7 for the Hip Outcome Score-Sport-Specific Subscale. In the older study group, the score improvement from preoperatively to 2 years' follow-up was 61.2 to 82.2 for the modified Harris Hip Score, 59.9 to 80.4 for the Non-Arthritic Hip Score, 63.9 to 83 for the Hip Outcome Score-Activities of Daily Living, and 41.2 to 64.6 for the Hip Outcome Score-Sport-Specific Subscale. All improvements in both groups were statistically significant at the 2-year postoperative follow-up (P < .001). There was no significant difference for all patient-reported outcome (PRO) scores at final follow-up between both groups. When we compared the change in PRO scores (

  13. Intake of high-fructose corn syrup sweetened soft drinks, fruit drinks and apple juice is associated with prevalent arthritis in US adults, aged 20-30 years.

    There is a link between joint and gut inflammation of unknown etiology in arthritis. Existing research indicates that regular consumption of high-fructose corn syrup sweetened (HFCS) soft drinks, but not diet soft drinks, may be associated with increased risk of seropositive rheumatoid arthritis (RA) in women, independent of other dietary and lifestyle factors. One unexplored hypothesis for this association is that fructose malabsorption, due to regular consumption of excess free fructose (EFF) and HFCS, contributes to fructose reactivity in the gastrointestinal tract and intestinal in situ formation of enFruAGEs, which once absorbed, travel beyond the intestinal boundaries to other tissues and promote inflammation. In separate studies, the accumulation of advanced glycation end-products has been associated with joint inflammation in RA. Objective of this study was to assess the association between EFF beverages intake and non-age, non-wear and tear-associated arthritis in US young adults. In this cross sectional study of 1209 adults aged 20-30y, (Nutrition and Health Examination Surveys 2003-2006) exposure variables were high EFF beverages, including HFCS sweetened soft drinks, and any combination of HFCS sweetened soft drinks, fruit drinks (FD) and apple juice, referred to as tEFF. Analyses of diet soda and diet FD were included for comparison. The outcome was self-reported arthritis. Rao Scott Ҳ(2) was used for prevalence differences and logistic regression for associations, adjusted for confounders. Young adults consuming any combination of high EFF beverages (tEFF) ⩾5 times/week (but not diet soda) were three times as likely to have arthritis as non/low consumers (odds ratios=3.01; p⩽0.021; 95% confidence intervals=1.20-7.59), independent of all covariates, including physical activity, other dietary factors, blood glucose and smoking. EFF beverage intake is significantly associated with arthritis in US adults aged 20-30 years, possibly due to the

    The 1979 Massachusetts law raising the legal drinking age from 18 to 20 is examined--the effects on the drinking, drinking and driving, and nonfatal and fatal crash involvement of 16-17 yr-olds, teenagers immediately younger than those targeted by the law. Data from Massachusetts are compared with those from New York State, where the drinking age remained at 18. A total of 3 yr of survey data from the two states and 6 yr of data from the Department of Transportation's Fatal Accident Reporting System provide for pre- and postlaw comparisons. The findings suggest that raising the drinking age had minimal effects on the drinking behavior of Massachusetts teenagers. Although there was a significant reduction in nonfatal crashes in Massachusetts compared with New York, no decline in single-vehicle nighttime fatal crashes or in overall fatal crashes was observed. It is suggested that changes in the drinking age may offer some reduction in teenage driving after drinking and traffic crash involvement, but that teenage drinking and driving after drinking remain serious problems even in states that raise their drinking ages.

    2012-04-01

    The Canadian Society for Exercise Physiology (CSEP), with assistance from multiple partners, stakeholders, and researchers, developed the first Canadian Sedentary Behaviour Guidelines for the Early Years (aged 0-4 years). These national guidelines are in response to a call from health and health care professionals, child care providers, and fitness practitioners for guidance on sedentary behaviour in the early years. The guideline development process followed the Appraisal of Guidelines for Research Evaluation (AGREE) II framework. The recommendations are informed by evidence from a systematic review that examined the relationships between sedentary behaviour (predominantly screen time) and health indicators (healthy body weight, bone and skeletal health, motor skill development, psychosocial health, cognitive development, and cardio-metabolic disease risk factors) for three age groups (infants aged <1 year; toddlers aged 1-2 years; preschoolers aged 3-4 years). Evidence from the review was assessed using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) system. The new guidelines include a preamble to provide context, followed by the specific recommendations. The final guidelines benefitted from extensive on-line consultations with input from >900 domestic and international stakeholders, end-users, and key informants. The final guidelines state: for healthy growth and development, caregivers should minimize the time infants (aged <1 year), toddlers (aged 1-2 years), and preschoolers (aged 3-4 years) spend being sedentary during waking hours. This includes prolonged sitting or being restrained (e.g., stroller, high chair) for more than 1 h at a time. For those under 2 years, screen time (e.g., TV, computer, electronic games) is not recommended. For children 2-4 years, screen time should be limited to under 1 h per day; less is better.

Methods: The data of 39 499 death cases aged 35-79 years in 2016 in Tianjin were collected, the risks for deaths caused by smoking related diseases and excess deaths as well as effects of smoking cessation were analyzed after adjusting 5 year old age group, education level and marital status. Results: Among the 39 499 deaths cases, 1 589 (13.56%) were caused by smoking, the percentage of the excess mortality of lung cancer caused by smoking was highest (47.60%); the risk of death due to lung cancer in smokers was 2.75 times higher than that in non-smokers (95 %CI : 2.47-3.06). Among the female deaths, 183 (7.29%) were caused by smoking, the percentage of the excess mortality of lung cancer was highest (28.90%); and the risk of death of lung cancer in smokers was 4.04 times higher than that in non-smokers (95 %CI : 3.49-4.68). The OR for disease in ex-smokers was 0.80 compared with 1.00 in smokers (95 %CI : 0.72-0.90). The OR in males who had quitted smoking for ≥10 years was lower (0.74, 95 %CI : 0.63-0.86) than that in those who had quitted smoking for 1-9 years (0.85, 95 %CI : 0.74-0.98), but the difference was not significant. Conclusion: Smoking is one of the most important risk factors for deaths in residents in Tianjin. Smoking cessation can benefit people's health.

    Mantel-Haenszel odds ratio (OR) with 95% confidence interval (CI). Because of disparate interventions and outcome measures, we did not conduct meta-analysis. Five trials met the inclusion criteria. The studies included a total of 1503 women, with a mean of 301 participants. The trials compared the following contraceptives: combined oral contraceptive (COC) versus transdermal contraceptive patch, vaginal contraceptive ring, or levonorgestrel intrauterine system 20 µg/day (LNG-IUS 20); LNG-IUS 12 µg/day (LNG-IUS 12) versus LNG-IUS 16 µg/day (LNG-IUS 16); and LNG-IUS 20 versus the copper T380A intrauterine device (IUD). In the trials comparing two different types of methods, the study arms did not differ significantly for contraceptive efficacy or continuation. The sample sizes were small for two of those studies. The only significant outcome was that a COC group had a higher proportion of women who discontinued for 'other personal reasons' compared with the group assigned to the LNG-IUS 20 (OR 0.27, 95% CI 0.09 to 0.85), which may have little clinic relevance. The trial comparing LNG-IUS 12 versus LNG-IUS 16 showed similar efficacy over one and three years. In three trials that examined different LNG-IUS, continuation was at least 75% at 6 to 36 months. We considered the overall quality of evidence to be moderate to low. Limitations were due to trial design or limited reporting. Different doses in the LNG-IUS did not appear to influence efficacy over three years. In another study, continuation of the LNG-IUS appeared at least as high as that for the COC. The current evidence was insufficient to compare efficacy and continuation rates for hormonal and intrauterine contraceptive methods in women aged 25 years and younger.

    Inadequate vitamin D status is associated with secondary hyperparathyroidism and increased bone turnover and bone loss, which in turn increases fracture risk. The objective of this study is to assess the prevalence of inadequate vitamin D status in European women aged over 80 years. Assessments of serum 25-hydroxyvitamin D levels (25(OH)D) were performed on 8532 European women with osteoporosis or osteopenia of which 1984 were aged over 80 years. European countries included in the study were: France, Belgium, Denmark, Italy, Poland, Hungary, United Kingdom, Spain and Germany. Two cut-offs of 25(OH)D inadequacy were fixed: <75 nmol/L (30 ng/ml) and <50 nmol/L (20 ng/ml). Mean (SD) age of the patients was 83.4 (2.9) years, body mass index was 25.0 (4.0) kg/m(2) and level of 25(OH)D was 53.3 (26.7) nmol/L (21.4 [10.7] ng/ml). There was a highly significant difference of 25(OH)D level across European countries (p<0.0001). In these women aged over 80 years, the prevalence of 25(OH)D inadequacy was 80.9% and 44.5% when considering cut-offs of 75 and 50 nmol/L, respectively. In the 397 (20.0%) patients taking supplemental vitamin D with or without supplemental calcium, the mean serum 25(OH)D level was significantly higher than in the other patients (65.2 (29.2) nmol/L vs. 50.3 (25.2) nmol/L; P<0.001). This study indicates a high prevalence of vitamin D (25(OH)D) inadequacy in old European women. The prevalence could be even higher in some particular countries.

    Educational attainment is the leading social determinant of health, but few studies of prevention programs have examined whether the programs are associated with educational attainment outcomes after the mid-20s, especially for large-scale programs that provide a longer duration of services. To examine the association between a preschool to third grade intervention and educational attainment at midlife and differences by program duration, sex, and parental educational level. This matched-group, alternative intervention study assessed 1539 low-income minority children born in 1979 or 1980 who grew up in high-poverty neighborhoods in Chicago, Illinois. The comparison group included 550 children primarily from randomly selected schools participating in the usual early intervention. A total of 989 children who entered preschool in 1983 or 1984 and completed kindergarten in 1986 were included in the Chicago Longitudinal Study and were followed up for 27 to 30 years after the end of a multicomponent intervention. A total of 1398 participants (90.8%) in the original sample had educational attainment records at 35 years of age. The study was performed from January 1, 2002, through May 31, 2015. The Child-Parent Center Program provides school-based educational enrichment and comprehensive family services from preschool to third grade (ages 3-9 years). Educational outcomes from administrative records and self-report included school dropout, 4-year high school graduation, years of education, postsecondary credential, and earned degrees from associate's to master's or higher. A total of 1539 participants (mean [SD] age, 35.1 [0.32] years; 1423 [92.9%] black and 108 [7.1%] Hispanic) were included in the study. After weighting on 2 propensity scores, preschool participants had higher rates of postsecondary degree completion, including associate's degree or higher (15.7% vs 10.7%; difference, 5.0%; 95% CI, 1.0%-9.0%), master's degree (4.2% vs 1.5%; difference, 2.7%; 95% CI, 1

    To determine the causes of death and associated risk factors among women of reproductive age (WRA) in a tertiary institution in Port Harcourt, Nigeria. This was a retrospective survey of all deaths in women aged 15-49 years at the University of Port Harcourt Teaching Hospital that occurred from January 1, 2013 to December 31, 2015. Data retrieved from ward registers, death registers, and death certificates were analyzed with Epi Info version 7. Comparison of socioeconomic and demographic risk factors for maternal and nonmaternal deaths was done using a multivariate logistic regression model. There were 340 deaths in the WRA group over the 3-year period. The majority (155 [45.6%]) of the women were aged 30-39 years. There were 265 (77.9%) nonmaternal deaths and 75 (22.1%) maternal deaths. Among the nonmaternal deaths, 124 (46.8%) had infectious diseases, with human immunodeficiency virus being the most common cause of infection in this group. Breast cancer (13 [4.9%]), cervical cancer (12 [4.5%]), and ovarian cancer (11 [4.2%]) were the most common malignant neoplasms observed. Hypertensive disorders of pregnancy (31 [41.3%]) and puerperal sepsis (20 [26.7%]) were the most common causes of maternal deaths. Age and occupation were significantly associated with deaths in WRA ( p <0.05). Older women aged >30 years (odd ratio =1.86, 95% CI =1.07-3.23) and employed women (odds ratio =2.55, 95% CI =1.46-4.45) were more likely to die from nonmaternal than maternal causes. Most of the deaths were nonmaternal. Infectious diseases, diseases of the circulatory system, and malignant neoplasms were the major causes of death among WRA, with maternal deaths accounting for approximately a quarter. Public health programs educating women on safer sex practices, early screening for cancers, benefits of antenatal care, and skilled attendants at delivery will go a long way to reducing preventable causes of deaths among these women.

    The age-adjusted death rate for males aged 15-44 years was 10% lower in 2014 (156.6 per 100,000 population) than in 1999 (174.1). Among the five leading causes of death, the age-adjusted rates for three were lower in 2014 than in 1999: cancer (from 17.1 to 12.8; 25% decline), heart disease (20.1 to 17.0; 15% decline), and homicide (15.7 to 13.8; 12% decline). The age-adjusted death rates for two of the five causes were higher in 2014 than in 1999: suicide (20.1 to 22.5; 12% increase), and unintentional injuries (from 48.7 to 51.0; 5% increase).

    It is unclear whether mortality still is increased in acromegaly and whether there are gender-related differences. We dynamically assessed outcome during long-term follow-up in our nationwide cohort. We studied standardized mortality ratios (SMRs) relative to the general population and causes of death in acromegaly (n=333) compared with age- and gender-matched controls (n=4995). During 20 (0-33) years follow-up, 113 (34%) patients (n=333, 52% women) and 1334 (27%) controls (n=4995) died (P=0.004). SMR (1.9, 95% CI: 1.53-2.34, P<0.001) and all-cause mortality (OR 1.6, 95% CI: 1.2-2.2, P<0.001) were increased in acromegaly. Overall distribution of causes of death (P<0.001) differed between patients and controls but not cardiovascular (34% vs 33%) or cancer deaths (27% vs 27%). In acromegaly, but not in controls, causes of deaths shifted from 44% cardiovascular and 28% cancer deaths during the first decade, to 23% cardiovascular and 35% cancer deaths during the next two decades. In acromegaly, cancer deaths were mostly attributed to pancreatic adenocarcinoma (n=5), breast (n=4), lung (n=3) and colon (n=3) carcinoma. In acromegaly, men were younger than women at diagnosis (median 44.5 vs 50 years, P<0.001) and death (67 vs 76 years, P=0.0015). Compared with controls, women (36% vs 25%, P<0.01), but not men (31% vs 28%, P=0.44), had increased mortality. In acromegaly, men are younger at diagnosis and death than women. Compared with controls, mortality is increased during 20 years of follow-up, especially in women. Causes of deaths shift from predominantly cardiovascular to cancer deaths. © 2016 Society for Endocrinology.

    While most previous surveys on the clinico-epidemiological features of autoimmune bullous diseases (AIBDs) have predominantly focused on a single disease entity or just one disease group, there have been only few studies examining the incidence of various AIBDs. In the present study, we set out to determine the spectrum of AIBDs, to estimate the incidence of the most common AIBDs, and to examine their temporal trends in Central Serbia over a period of 20 years. We retrospectively recruited 1,161 new AIBD cases diagnosed in Central Serbia during the period from January 1991 to December 2010. The diagnosis was based on strict clinical, histological, and immunohistological evaluation. The incidence rates were: 4.35 per million population/year (pmp/year) for pemphigus, 4.47 pmp/year for pemphigoid, 1.42 pmp/year for dermatitis herpetiformis (DH), 0.25 pmp/year for linear IgA disease, and 0.08 pmp/year for epidermolysis bullosa acquisita. In the period observed, age-adjusted incidence rates significantly increased for pemphigus and particularly for pemphigoid, whereas they decreased, albeit not significantly, for DH. For the first time, our study evaluates the incidence rates of the entire spectrum of AIBDs in Serbia, and examines their temporal trends over a 20-year period. To the best of our knowledge, our finding of similar incidence rates for pemphigus and pemphigoid has previously not been reported. © 2016 Deutsche Dermatologische Gesellschaft (DDG).

    2008-01-01

    Purpose This study evaluated the influence of age at migration on cardiovascular mortality among older Mexican Americans immigrants. Methods A population-based cohort of Mexican-origin (N=907) participants aged 60+ was followed up to 8 years. The association between migration before age 20 compared to after age 20 and mortality was analyzed using multivariate Cox proportional models. Results Compared to those who migrated later, those who migrated before age 20 had higher incomes and education, were more likely to speak English, were culturally more Anglo, and more likely to be male. Immigration before age 20 was associated with higher rates of cardiovascular mortality (HR=2.39 95%CI [1.16,4.94]) compared to those migrating at older ages, even after adjustment for age, sex, education, income and baseline cardiovascular health. No age at migration differences were observed for non-cardiovascular deaths. Conclusions Mexican Americans who migrated in early life experienced higher cardiovascular disease death rates than later migrants. Early experiences related to migration may have consequences for late-life disease that are not mitigated by the higher socioeconomic status achieved by early migrants. Health or economic selection related to migration may play a role although accounting for health and socioeconomic status actually increased differences between early and later migrants.

    Although ranibizumab is widely used in age-related macular degeneration there is no systematic data available on the relation between treatment frequency and functional efficacy within the first 12 months of follow-up. A meta-analysis was performed on available MEDLINE literature. 47 relevant clinical studies (54 case series) could be identified covering 11706 treated eyes. Non-linear and linear regressions were calculated for the relation between treatment frequency and functional outcome (average gain in visual acuity, % of eyes losing less than 15 letters of visual acuity, % of eyes gaining ≥ 15 letters) within the first year of care. Mean improvement of average visual gain was +4.9 ± 3.6 (mean ± 1 standard deviation) letters (case-weighted: 3.3 letters). The average number of ranibizumab injections until month 12 was 6.3 ± 2.0 (case-weighted: 5.9). 92.4 ± 3.9% of eyes (case-weighted: 91.9%) lost less than three lines of visual acuity and 24.5 ± 8.2% (case-weighted: 23.3) gained more than 3 lines within the first year. Analysis of the relation between the number of injections and functional improvement indicated best fit for non-linear equations. A nearly stepwise improvement of functional gain occurred between 6.8 and 7.2 injections/year. A saturation effect of treatment occurred at higher injection frequency. The results of this meta-analysis clearly indicate a non-linear relation between the number of injections and functional gain of ranibizumab within the first 12 months of treatment. Treatment saturation seems to occur at a treatment frequency >7.2 injections within the first 12 months. Georg Thieme Verlag KG Stuttgart · New York.

    This test was administered to a sample of 314 17 years old Argentine subjects (157 boy and 157 girls), and to another sample of 240 Argentine subjects, consisting of 127 boys and 113 girls of 20 years of age. Means, standard deviations and percentile ranks for both samples were obtained. To compare groups of different sex and age test of significance for mean differences of independent samples were applied. Boys obtained scores significantly higher than girls, without taking into consideration the age, in Factors C (lower ego strength-higher ego strength), E (submissiveness-dominance), H (threctia-parmia), Q1 (conservativism of temperament-radicalism) and Q3 (low self-sentiment integration - high strength of self sentiment). Contrarywise, girl showed scores significantly higher than boys of the same age in factors I (harria-premsia), N (artlessness-shrewdness), O (untroubled adequacy-guilt proneness) and Q4 (low ergic tension-high ergic tension).

    To examine 1) temporal trends between 2005 and 2014 in the three most frequently used suicide means (firearms, hanging/suffocation, alcohol/drug/medicine overdose) by decedents aged 50+ years and 2) associations of suicide means with sociodemographic and precipitating factors. The National Violent Death Reporting System, 2005-2014, provided data (N = 46,857). Suicide means were identified from ICD-10 codes for underlying cause of death and coroner/medical examiner (CME) reports. Precipitating factors are based on either CME or law enforcement report. Age-group (50-64 and 65+ years) and gender-separate logistic regression analyses were used to examine study questions. In the 50-64 years age group, each advancing year (i.e., from 2005 to 2014) was associated with a 1% decrease in the odds of firearm use and a 6% increase in the odds of hanging/suffocation among men; a 9% increase in the odds of hanging/suffocation among women; and a 4% decrease in the odds of overdose among each gender. In the 65+ years age group, each advancing year was associated with a 4% increase in the odds of overdose among men. Physical health was a significant factor for firearm use among men (adjusted odds ratio: 1.47; 95% CI: 1.39-1.55) only. Regardless of gender and age, mental health and substance abuse problems and prior suicide attempts were associated with hanging/suffocation and overdose. Firearm use decreased among men aged 50-64 years between 2005 and 2014, but its use did not change among the other gender by age groups. With rapidly growing numbers of older adults, routine suicide risk assessments, firearm safety monitoring, and interventions to improve quality of life are needed.

    Background: Locoregional treatment of inflammatory breast cancer (IBC) is crucial because local relapses may be highly symptomatic and are commonly associated with distant metastasis. With a median follow-up of 20 years, we report here the long-term results of a monocentric clinical trial combining primary chemotherapy (CT) with a schedule of anthracycline-based CT and an alternating split-course of radiotherapy (RT Asterisk-Operator CT) without mastectomy. Methods and Materials: From September 1983 to December 1989, 124 women with nonmetastatic IBC (T4d M0) were treated with three cycles of primary AVCMF chemotherapy (anthracycline, vincristine, cyclophosphamide, methotrexate, and 5-fluorouracil) and then an alternating RT Asterisk-Operatormore » CT schedule followed by three cycles of FAC. Hormonal therapy was systematically administered: ovarian irradiation (12 Gy in four fractions) or tamoxifen 20 mg daily. Results: Local control was achieved in 82% of patients. The 10- and 20-year local relapse rates were 26% and 33%, respectively, but only 10% of locally controlled cases were not associated with concurrent distant metastasis. The 10- and 20-year overall survival rates were 39% and 19%, respectively. Severe fibrosis occurred in 54% of patients, grade 3 brachial plexus neuropathy in 4%, grade 2 pneumonitis in 9%. Grade 1, 2 and 3 cardiac toxicity was observed in 3.8%, 3.8% and 1.2% of cases respectively. Conclusions: This combined regimen allowed good long-term local control without surgery. Survival rates were similar to those obtained with conventional regimens (primary chemotherapy, total mastectomy, and adjuvant radiotherapy). Since IBC continues to be an entity with a dismal prognosis, this approach, safely combining preoperative or postoperative radiation therapy and systemic treatments, should be reassessed when suitable targeted agents are available.« less

    The following four issues were assessed in a group of 110 adults between the age of 20 and 59y: (1) the effect of age (regarded as a continuous variable) on polysomnographic sleep characteristics, habitual sleep-diary patterns, and subjective sleep quality; (2) the effects of age on morningness-eveningness; (3) the effects of morningness-eveningness on sleep, after controlling for the effects of age; and (4) the role of morningness-eveningness as a mediator of the age and sleep relationship. Increasing age was related to earlier habitual waketime, earlier bedtime, less time in bed and better mood and alertness at waketime. In the laboratory, increasing age was associated with less time asleep, increased number of awakenings, decreased sleep efficiency, lower percentages of slow-wave sleep (SWS) and rapid eye movement (REM) sleep, higher percentages of Stage 1 and 2, shorter REM latency and reduced REM activity and density. Increasing age was also associated with higher morningness scores. After controlling for the effects of age, morningness was associated with earlier waketime, earlier bedtime, less time in bed, better alertness at waketime, less time spent asleep, more wake in the last 2 h of sleep, decreased REM activity, less stage REM (min and percentage), more Stage 1 (min and percentage) and fewer minutes of Stage 2. For one set of variables (night time in bed, waketime, total sleep time, wake in the last 2 h of sleep and minutes of REM and REM activity), morningness-eveningness accounted for about half of the relationship between age and sleep. For another set of variables (bedtime, alertness at waketime, percentages of REM and Stage 1), morningness-eveningness accounted for the entire relationship between age and sleep. In conclusion, age and morningness were both important predictors of the habitual sleep patterns and polysomnographic sleep characteristics of people in the middle years of life (20-59 y).

    Although bilateral internal mammary artery (BIMA) grafting is performed with increasing regularity in elderly patients, whether it is truly beneficial, and therefore indicated, in these patients remains uncertain. We retrospectively investigated early and late outcomes of BIMA grafting in patients aged ≥75 years. We identified 460 patients aged ≥75 years from among 2,618 patients who underwent either single internal mammary artery (SIMA) grafting (n=293) or BIMA grafting (n=107). Early outcomes did not differ between the SIMA and BIMA patients (30-day mortality: 1.7% vs. 0%, P=0.39; sternal wound infection: 1.0% vs. 4.7%; P=0.057). Late outcomes, 10-year survival in particular, were improved in the BIMA group (36.6% vs. 48.1%, P=0.033). In the analysis of the results in propensity score-matched groups (196 patients in the SIMA group, 98 patients in the BIMA group), improved 10-year survival was documented in the BIMA group (34.8% vs. 47.6%, P=0.030). Cox proportional regression analysis showed SIMA usage (non-use of BIMA) to be a predictor for late mortality (hazard ratio: 0.65, 95% confidence interval: 0.43-0.98, P=0.042). We further compared outcomes between the total non-elderly patients (n=2,158) and total elderly patients (n=460). BIMA usage was similar, as was 30-day mortality (1.0% vs. 1.3%, respectively). A survival advantage, with no increase in early mortality, can be expected from BIMA grafting in patients aged ≥75 years. (Circ J 2016; 80: 1756-1763).

    Central nervous system tumours comprise a heterogeneous group of neoplasms with great histological diversity. Despite the rising prevalence of these tumours in developing countries, some places like Mexico and Latin America have no representative studies that show the real impact of these tumours in our population. To describe the characteristics of the primary and secondary tumours of the central nervous system in the last 20 years in a Mexican institution. Patients with histopathological diagnosis from 1993 to 2013 in our institution, grouping them according to WHO classification 2007, characterising them by age group, gender, and anatomical location. There were a total of 511 tumours of the central nervous system. Of those, 292 were women and 219 men, with a ratio 1.3: 1, and a mean age of 49.3 years. Tumours with higher prevalence were: Meningeal tumours, 171 (33%), followed by neuroepithelial, 121 (24%). Astrocytoma had the highest prevalence in paediatric patients, whereas in those older than 20 years it was the meningioma. The supratentorial location was the most involved. This is the first study of a series of cases in Mexico that is performed by taking into account benign and malignant tumours of the central nervous system, with patients of all age groups with a range of 20 years. While this work only represents a retrospective analysis of an institution, it can be a strong indication of the epidemiology of these tumours in our environment. Copyright © 2016.

    Maps of virtual geomagnetic poles derived from international geomagnetic reference field models show large lobes with significant departures from the spin axis. These lobes persist in field models for the last few millenia. The anomalous lobes are associated with observation sites at extreme southerly latitudes. To determine whether these features persist for millions of years, paleomagnetic vector data from the continent of Antarctica are essential. We present here new paleomagnetic vector data and 40Ar/39Ar ages from lava flows spanning the Brunhes and Matuyama Chrons from the vicinity of McMurdo Sound, Antarctica. Oriented paleomagnetic samples were collected from 50 lava flows by E. Mankinen and A. Cox in the 1965–1966 austral summer season. Preliminary data based largely on the natural remanent magnetization (NRM) directions were published by Mankinen and Cox [1988]. We have performed detailed paleomagnetic investigations of 37 sites with multiple fully oriented core samples to investigate the reliability of results from this unique sample collection. Of these, only one site fails to meet our acceptance criteria for directional data. Seven sites are reversely magnetized. The mean normal and reverse directions are antipodal. The combined mean direction has  = 12,  = −86, α = 4, κ = 37 and is indistinguishable from that expected from a GAD field. We obtained reproducible absolute paleointensity estimates from 15 lava flows with a mean dipole moment of 49 ZAm2 and a standard deviation of 28 ZAm2. 40Ar/39Ar age determinations were successfully carried out on samples from 18 of the flows. Our new isotopic ages and paleomagnetic polarities are consistent with the currently accepted geomagnetic reversal timescales.

    This study focused on the associations between older adults' health-related problems and their late-life alcohol consumption and drinking problems. A sample of 719 late-middle-aged community residents (55-65 years old at baseline) participated in a survey of health and alcohol consumption and this survey was followed 10 years and 20 years later. Health-related problems increased and alcohol consumption and drinking problems declined over the 20-year interval. Medical conditions, depressive symptoms, medication use, and acute health events were associated with a higher likelihood of abstinence; acute health events were also associated with less alcohol consumption. In contrast, reliance on alcohol to reduce pain was linked to more alcohol consumption. Moreover, an individual's overall health burden and reliance on alcohol to reduce pain were associated with more drinking problems. Reliance on alcohol to reduce pain potentiated the association between health burden, alcohol consumption and drinking problems. Older adults who have more health problems and rely on alcohol to manage pain are at elevated risk for drinking problems. Health care providers should target high-risk older adults, such as those who drink to reduce pain, for screening and brief interventions to help them identify new ways to cope with pain and curtail their drinking.

    To date, there is no unified approach to evaluating and treating patients with suspected prostate cancer taking into account their age and comorbidities. That was the rationale for conducting this study. To assess the clinical course of prostate cancer in men of all ages with comorbidities. The study included 408 patients aged 50 to 92 years (mean age 74.3 years) with histologically verified prostate cancer. 30 (7.4%) patients had stage T1 disease, 273 (66.9%) - T2, 91 (22.3%) - T3 and 14 (3.4%) - T4. The maximum follow-up was 22 years, the minimum one - 6 months (on average 15.4 years). During the follow-up 159 patients died (39%), 51 of them (32%) of prostate cancer, 108 (68%) - from other diseases. Among the latter the causes of death were cancer (20.4%), cardiovascular and bronchopulmonary diseases (79.6%). Cancer-specific survival rate was 41.4 +/-12,4%, the survival rate for other diseases 23.4 +/-10,6% (p<0.05). We need a differentiated approach to selecting treatment for patients with prostate cancer, especially of old age, including the option for active surveillance of patients with clinically insignificant prostate cancer.

  2. A high-precision 40Ar/39Ar age for the Nördlinger Ries impact crater, Germany, and implications for the accurate dating of terrestrial impact events

    40Ar/39Ar dating of specimens of moldavite, the formation of which is linked to the Ries impact in southern Germany, with a latest-generation ARGUS VI multi-collector mass spectrometer yielded three fully concordant plateau ages with a weighted mean age of 14.808 ± 0.021 Ma (± 0.038 Ma including all external uncertainties; 2σ; MSWD = 0.40, P = 0.67). This new best-estimate age for the Nördlinger Ries is in general agreement with previous 40Ar/39Ar results for moldavites, but constitutes a significantly improved precision with respect to the formation age of the distal Ries-produced tektites. Separates of impact glass from proximal Ries ejecta (suevite glass from three different surface outcrops) and partially melted feldspar particles from impact melt rock of the SUBO 18 Enkingen drill core failed to produce meaningful ages. These glasses show evidence for excess 40Ar introduction, which may have been incurred during interaction with hydrothermal fluids. Only partially reset 40Ar/39Ar ages could be determined for the feldspathic melt separates from the Enkingen core. The new 40Ar/39Ar results for the Ries impact structure constrain the duration of crater cooling, during the prevailing hydrothermal activity, to locally at least ∼60 kyr. With respect to the dating of terrestrial impact events, this paper briefly discusses a number of potential issues and effects that may be the cause for seemingly precise, but on a kyr-scale inaccurate, impact ages.

  4. Some economic consequences of an ageing and declining population in Denmark.

    PubMed

    Leeson, G W

    1983-01-01

    Figures for 1981 indicate that Denmark has a fertility level of 1.45 which has been below replacement level since 1968. In that same time period, natural increase has decreased from over 27,000 in 1968 to only 1354 in 1980 and a negative natural increase in 1981 with deaths outnumbering births by 3001. Even during the depression in the 1930's, net population increase was between 6-9/1000 with a fertility level which hovered around replacement level. At that time, the number of females in the childbearing ages was enough to provide population growth, whereas the number is much less today. Population increase is only 0.3/1000. The national population projections for Denmark for 1981-2010 assume an increase in the fertility level from 1.45-1.70 by 1991 after which it remains constant. The number of 20-39 year olds increased steadily until 1945 after which there was a decline as the cohorts from periods with low fertility levels entered this age group, but this was again followed by a steady increase to the present day. The number of females aged 0-39 years is expected to decrease in all age groups to the year 2000. Those aged 40-59 increased in numbers from 1920 to the mid 1960s, since then they have decreased in number, but an increase is forcast for the remainder of the century. The number of elderly females also increased steadily from 1930-80, from about 200,000 to over 550,000; this is expected to continue until 1990 when a short-term decline will set in. Regarding the economic and social consequences of these trends, it is shown that the present decline in fertility has its origins in a period of low unemployment and its negative growth while there was still relatively low unemployment and economic growth. In 1973 the unemployed rate was 0.9% of the work force and this rose to 9.2% in 1981. The Danish population has aged from one with 1/4 million people aged 60 and over at the turn of the century to about 1 million of that age today. Also, the aged themselves

    The Hawaii Scientific Drilling Project recovered core from a 3.5 km deep hole from the flank of Mauna Kea volcano, providing a long, essentially continuous record of the volcano's physical and petrologic development that has been used to infer the chemical and physical characteristics of the Hawaiian mantle plume. Determining a precise accumulation rate via 40Ar/39Ar dating of the shield-stage tholeiites, which constitute 95-98% of the volcano's volume is challenging. We applied40Ar/39Ar dating using laser- and furnace-heating in two laboratories (Berkeley and Curtin) to samples of two lava flows from deep in the core (˜3.3 km). All determinations yield concordant isochron ages, ranging from 612 ± 159 to 871 ± 302 ka (2σ; with P ≥ 0.90). The combined data yield an age of 681 ± 120 ka (P = 0.77) for pillow lavas near the bottom of the core. This new age, when regressed with 40Ar/39Ar isochron ages previously obtained for tholeiites higher in the core, defines a constant accumulation rate of 8.4 ± 2.6 m/ka that can be used to interpolate the ages of the tholeiites in the HSDP core with a mean uncertainty of about ±83 ka. For example at ˜3300 mbsl, the age of 664 ± 83 ka estimated from the regression diverges at the 95% confidence level from the age of 550 ka obtained from the numerical model of DePaolo and Stolper (1996). The new data have implications for the timescale of the growth of Hawaiian volcanoes, the paleomagnetic record in the core, and the dynamics of the Hawaiian mantle plume.

  7. Personality Stability From Age 14 to Age 77 Years

    PubMed Central

    2016-01-01

    There is evidence for differential stability in personality trait differences, even over decades. The authors used data from a sample of the Scottish Mental Survey, 1947 to study personality stability from childhood to older age. The 6-Day Sample (N = 1,208) were rated on six personality characteristics by their teachers at around age 14. In 2012, the authors traced as many of these participants as possible and invited them to take part in a follow-up study. Those who agreed (N = 174) completed a questionnaire booklet at age 77 years, which included rating themselves and asking someone who knew them well to rate them on the same 6 characteristics on which they were rated in adolescence. Each set of 6 ratings was reduced to the same single underlying factor, denoted dependability, a trait comparable to conscientiousness. Participants’ and others’ older-age personality characteristic ratings were moderately correlated with each other, and with other measures of personality and wellbeing, but correlations suggested no significant stability of any of the 6 characteristics or their underlying factor, dependability, over the 63-year interval. However, a more complex model, controlling rater effects, indicated significant 63-year stability of 1 personality characteristic, Stability of Moods, and near-significant stability of another, Conscientiousness. Results suggest that lifelong differential stability of personality is generally quite low, but that some aspects of personality in older age may relate to personality in childhood. PMID:27929341

The incidence of past surgical procedures was increased significantly with advancing maternal age; this was attributed mainly to non-gynecological surgical procedures (p= O 0.04). Among women <3 4 years 41,.% (54/131) reported past surgery, while in the age groups between 35-39 and >≥ 0 years the figures were 57,.% (146/254) and 59, 1% (65/110) respectively .The increase of maternal age was related to significantly more frequent complications in the second half of pregnancy --reeclampsia, placenta praevia, placental abruption and preterm delivery. The incidence of preeclampsia increased from 1,.3% (2/131) in the age group <3 4, to 3,.3% (10/254) for those aged 35-39 and to 7,.7% (8/110) --or the ones _≥ 0 (p= O 0.5). The combined incidence of placenta praevia and placental abruption was also significantly higher in women of more advanced age (p= 0 ,.056). In the age group <3 4 no such cases were registered while in women aged 35-39 the incidence of these complications was 3, 14% (8/254) and for the age group >≥ 0 it was 8,.8% (9/110). The combined incidence of placenta previa and placental abruption was considered because of the small number of cases. The complications cited above were significantly more frequent in women with accompanying medical disorders (p = 0,001). The incidence of preterm deliveries increased significantly with maternal age --rom 10,.% (14/131) for women <3 4 to 25,.% (52/208) --or those between 35-39 and 21,.% (20/93) --or those _≥ 0 years of age (p= 0 ,.13). The combined preterm delivery rate was considered in the study (spontaneous and induced). In our study maternal age >≥ 5 years was related to significantly more frequent conception by ART history of accompanying medical disorders, past surgery (non-gynecological) and complications in the second half of pregnancy (preeclampsia, placenta praevia, placental abruption and preterm delivery).

    Physical activity and sports have repeatedly been reported to be associated with telomere length. We studied the association of different types of sports across different stages of life on relative leukocyte telomere length (rLTL) in advanced age.815 participants (397 men) from the Berlin Aging Study II aged over 61 years were included in the analysis. rLTL was measured by real time PCR and physical activity was determined retrospectively by questionnaire, assessing type and duration of sports in the past as well as currently. Five separate multiple linear regression models adjusted for various control variables were performed. 67.3% of participants exercised currently, whereas 19.4% performed sports only between the age of 20 and 30. rLTL was higher in subjects who stated to exercise currently (N = 456), and in subjects who engaged in endurance (N = 138) or intensive activity sports (N = 32). Current physical activity was positively associated with rLTL in the risk factor adjusted regression model (β = 0.26, p < 0.001) and practicing sports for a minimum of 10 years preceding the assessment had a significant effect on rLTL (β = 0.39, p = 0.011). The highest impact was seen for intensive activity sports (β = 0.79, p < 0.001) and physical activity since at least 42 years (β = 0.47, p = 0.001). However, physical activity only between 20 and 30 years of age did not affect rLTL in old age when compared to no sports at all (β = -0.16, p = 0.21). Physical activity is clearly associated with longer rLTL. The effect is seen with longer periods of physical activity (at least 10 years), with intensive sports activities having the greatest impact on rLTL. Our data suggest that regular physical activity for at least 10 years is necessary to achieve a sustained effect on rLTL.

    Assess whether adolescent oligomenorrhea (age 14-19) tracks into young adulthood (age 20-28) and predicts increased cardiometabolic risk factors, metabolic syndrome (MetS), and impaired fasting glucose-type II diabetes mellitus (IFG+T2DM). Prospective study of menstrual cyclicity and its metabolic effects in 865 black and white schoolgirls from age 9 to 19, and 605 of these 865 girls from age 20 to 28. Patterns of menstrual delays (oligomenorrhea) during ages 14-19 and ages 20-28 were closely related (p<.0001). Adolescent menses delay (ages 14-19, p<.0001), mean insulin (ages 20-28, p=.0003), and self-identified polycystic ovary syndrome (PCOS, p=.049) predicted ages 20-28 menses delay. Menses delays during ages 14-19 and 20-28, and, their interaction product were correlated with IFG+T2DM and MetS at ages 20-28. Waist circumference (ages 20-28, p<.0001), mean triglyceride (ages 20-28, p=.005), and the number of average menstrual cycles≥42 days (ages 20-28, p=.04) predicted IFG+T2DM (ages 20-28). MetS (ages 9-19, p<.0001), mean insulin (ages 20-28, p=.0002), the number of ≥42 day gaps between menstrual periods (ages 20-28, p=.02), and cigarette smoking at age 18-19 (p=.04) were significant explanatory variables for MetS at ages 27-28. As MetS status category changed from age 14-19 to 27-28 from best to worst: (no → no), (yes → no), (yes → yes), (no → yes), the number of women with ≥2 menses delays during ages 20-28 rose from 3% to 4% to 15% to 17%, p=.0001. MetS status change from age 9-19 to 27-28 was positively associated with mean insulin (age 20-28, p<.0001), cigarette smoking (age 24-25, p=.01) and the number of menses delays during ages 20-28 (p=.04). Menstrual patterns track from adolescence to young adulthood, and oligomenorrhea predicts MetS and IFG+T2DM. Patterns of menses delays in adolescence should be considered as a significant risk factor for future development of young adult IFG+T2DM, MetS, oligomenorrhea, and polycystic ovary syndrome

    Many studies addressing age-related changes in driving performance focus on comparing young vs. older drivers, which might lead to the biased conclusion that driving performance decreases only after the age of 65. The main aim of the study was to show that changes in driving performance are progressive throughout the adult years. A sample of 351 drivers aged 20 to 80 was assessed for their reaction times while driving between road cones. The drivers were exposed to 2 conditions varying according to task complexity. In single task conditions, the drivers performed a full stopping maneuver at a given signal; in dual task conditions, the drivers were distracted before the signal for stopping maneuver was triggered. Reaction times were compared across conditions and age groups. The results showed that both reaction times and variability of driving performance increased progressively between the ages of 20 and 80. The increase in both reaction times and variability was greater in the complex task condition. The high-performing quarter of elderly drivers performed equally well or better than younger drivers did. The data clearly supported the claim that driving performance changes steadily across age groups: both mean reaction time and interindividual variability progressively increase with age. In addition, a significant group of older drivers was identified who did not show the expected age-related decrease in performance. The findings have important implications, suggesting that in relation to driving, aging is a progressive phenomenon and may lead to variety of driving performance; age-related studies of driving performance should put more emphasis on investigating changes across the whole driver age range rather than only comparing younger and older drivers.

    To explore attitudes towards family formation and fertility awareness among Danish female healthcare professionals. We collected cross-sectional baseline data from a prospective cohort study of 863 women, ranging in age from 20 to 40 years, working at a hospital in Denmark. Information about participants' intentions and attitudes towards family formation and fertility knowledge was gathered by means of a questionnaire. Only 2% of the respondents did not want children. Most women believed that motherhood is important, and hoped to have two to three children. About half of the respondents intended to have their last child after the age of 35 years. The most important prerequisites for family formation included: living in a stable relationship, having completed one's studies, a sound financial situation, a job that can be kept when having children, access to public child day care, and the possibility of travelling. As many as 50% of women underrated the impact of a woman's age on fertility, and overestimated the success rates of assisted reproductive technology (ART) treatments. Many female healthcare professionals contemplated giving birth after the age of 35 years. Knowledge of fertility and ART success rates is needed to make well-informed decisions about when to have children.

    The malnutrition of children under five years of age constitutes a major public health problem in most developing countries. A cross-section study was carried in 2003 in the northern part of Côte d'Ivoire to determine the prevalence of chronic malnutrition and to identify risk factors among children under five years of age living in urban and rural areas of the northern part of Côte d'Ivoire. A total of 292 and 268 children under five years of age residing respectively in urban and rural areas were included in the study. Their median age was 24 months. Chronic malnutrition was more frequent in children from rural areas (39.9%) than in those living in urban areas (16.7%). Malnutrition was significantly associated with the type of food consumed by children under two years of age in urban areas, and it was strongly linked to emaciation of the mother and presence of childhood fever in rural areas. In light of these results, we advocate a healthy diet and adequate health status for the mother and child to improve the nutritional status of children. Moreover, these results need to be completed and complemented by further studies for more detailed information to contribute to a better definition of actions to fight efficiently against malnutrition among children of the northern part of Côte d'Ivoire.

    To describe sleep duration patterns of adults over a 20-year period; to compare sociodemographic, lifestyle, and health characteristics across these patterns; and to relate the patterns to sleep quality. The study population consisted of 3695 adults aged 20 to 59 years at baseline. Five measurements of self-reported sleep duration were used to compose seven patterns from 1987 to 2012: persistent short (≤6 hours), moderate (7-8 hours), or long (≥9 hours) sleep duration and several changing patterns (varying and became short, moderate, or long sleepers). Multinomial logistic regression analyses were used to compare characteristics across sleep duration patterns. About 56% of the adults had persistent moderate sleep duration over 20 years. This group had a better sleep quality than the other groups. Of the adults who changed in their sleep duration (40%), 43% became a short sleeper. Sleep duration patterns that deviate from persistent moderate sleep duration were associated with physical inactivity during leisure time (odds ratios [ORs] and 95% confidence intervals [95% CIs] varied between 1.26 [1.04-1.53] and 1.58 [1.06-2.37]) and with poor self-rated health (ORs [95% CIs] varied between 1.50 [1.20-1.87] and 2.15 [1.48-3.12]). Nearly half of the adults did not have persistent moderate sleep duration over a 20-year period and more than one-sixth became short sleeper. This is reason for concern considering the adverse health status associated with short and long sleep duration. Leisure-time physical activity is a potential important target to prevent unfavorable changes in sleep duration over the life course. © Sleep Research Society 2017.

    This study describes trends in dietary diversity and food intake over 12 years according to age at first participation in the study. Prospective cohort study. The National Institute for Longevity Sciences - Longitudinal Study of Aging, a community-based study. Participants included 922 men and 879 women who participated in the first study-wave (age, 40-79 years) and also participated in at least one study-wave from the second to seventh study-wave. Study-waves were conducted biennially. Dietary intake was calculated from 3-day dietary records with photographs. Dietary diversity was determined using the Quantitative Index for Dietary Diversity based on food intake. A mixed-effects model was used to estimate linear changes in dietary diversity and food intake over 12 years according to age at first study-wave. Mean (standard deviation (SD)) follow-up time and number of study-wave visits were 9.5 (3.7) years and 5.4 (1.8), respectively. Mean (SD, range) dietary diversity score was 0.86 (0.06, 0.52-0.96) in men and 0.88 (0.04, 0.66-0.96) in women, respectively. Fixed effects for interactions of age and time with dietary diversity score were statistically significant (p<0.05). The slope of dietary diversity among men aged 40 to 55 years increased (40-year-old slope = 0.00093/year, p<0.01; 55-year-old slope = 0.00035/year, p=0.04), with a decreasing trend started at 65 years old, although this trend was not significant (65-year-old slope = -0.00003/year, p=0.88; 79-year-old slope = -0.00057/year, p=0.21). The slope of dietary diversity among women aged 40 to 44 years increased (40-year-old slope = 0.00053/year, p=0.02; 44-year-old slope = 0.00038/year, p=0.04), whereas the slope of dietary diversity among women aged 63 to 79 years decreased (63-year-old slope = -0.00033/year, p=0.03; 79-year-old slope = -0.00092/year, p<0.001). Fruit, milk and dairy intake decreased in men around their 60s; milk and dairy intake decreased in women around their 50s; and beans and fruit

    Low-and middle-income countries (LMICs) are experiencing a nutritional transition in which the burden of obesity tends to shift towards the lower-socioeconomic status (SES) group. We propose a system dynamics (SD) model for assessing the nutritional stage dynamics of the Colombian urban population by age and SES projected to 2030. This SD model captures the ageing population according to body mass index (BMI) categories and SES. In this model, the transference rates (TRs) between BMI categories by age and SES are estimated using a heuristic based on data obtained from national surveys. The simulation results show that the Colombian population, particularly those aged 20 to 39 years with a lower SES, is moving towards the overweight and obese categories. The TRs for overweight and obese categories in the lower SES group (the mean TR from not overweight to overweight = 0.0215 (per year) and mean TR from overweight to obese = 0.0098 (per year)) are increasing more rapidly than the those in the middle (the mean TR from not overweight to overweight = 0.0162 (per year) and mean TR from overweight to obese = 0.0065 (per year)) and higher SES groups (the mean TR from not overweight to overweight = 0.0166 and mean TR from overweight to obese = 0.0054 (per year)). Additionally, from 2005 to 2010, individuals aged 20 to 39 years had the highest TRs towards the overweight and obese categories (from 0.026 to 0.036 per year and from 0.0064 to 0.012 per year, respectively). The TRs also indicated that children aged 0 to 14 years are moving from the obese to overweight and from the overweight to not overweight categories. These TRs show that the Colombian population is experiencing an SES-related nutritional transition that is affecting the lower SES population. The proposed model could be implemented to assess the nutritional transitions experienced in other LMICs. PMID:29420563

    The aim of the present large population-based cohort study is to explore the risk factors of age-related mortality in liver transplant recipients in Taiwan. Basic information and data on medical comorbidities for 2938 patients who received liver transplants between July 1, 1998, and December 31, 2012, were extracted from the National Health Insurance Research Database on the basis of ICD-9-codes. Mortality risks were analyzed after adjusting for preoperative comorbidities and compared among age cohorts. All patients were followed up until the study endpoint or death. This study finally included 2588 adults and 350 children [2068 (70.4%) male and 870 (29.6%) female patients]. The median age at transplantation was 52 (interquartile range, 43-58) years. Recipients were categorized into the following age cohorts: <20 (n = 350, 11.9%), 20-39 (n = 254, 8.6%), 40-59 (n = 1860, 63.3%), and ≥60 (n = 474, 16.1%) years. In the total population, 428 deaths occurred after liver transplantation, and the median follow-up period was 2.85 years (interquartile range, 1.2-5.5 years). Dialysis patients showed the highest risk of mortality irrespective of age. Further, the risk of death increased with an increase in the age at transplantation. Older liver transplant recipients (≥60 years), especially dialysis patients, have a higher mortality rate, possibly because they have more medical comorbidities. Our findings should make clinicians aware of the need for better risk stratification among elderly liver transplantation candidates.

    It is unclear whether a woman's age influences her risk of cervical intraepithelial neoplasia grade 3 or worse (CIN3+) upon detection of HPV. A large change in risk as women age would influence vaccination and screening policies. Among 972,029 women age 30-64 undergoing screening with Pap and HPV testing (Hybrid Capture 2, Qiagen, Germantown, MD) at Kaiser Permanente Northern California (KPNC), we calculated age-specific 5-year CIN3+ risks among women with HPV infections detected at enrollment, and among women with "newly detected" HPV infections at their second screening visit. Women (57,899, 6.0%) had an enrollment HPV infection. Among the women testing HPV negative at enrollment with a second screening visit, 16,724 (3.3%) had a newly detected HPV infection at their second visit. Both enrollment and newly detected HPV rates declined with age (p < 0.001). Women with enrollment versus newly detected HPV infection had higher 5-year CIN3+ risks: 8.5% versus 3.9%, (p < 0.0001). Risks did not increase with age but declined slightly from 30-34 years to 60-64 years: 9.4% versus 7.4% (p = 0.017) for enrollment HPV and 5.1% versus 3.5% (p = 0.014) for newly detected HPV. Among women age 30-64 in an established screening program, women with newly detected HPV infections were at lower risk than women with enrollment infections, suggesting reduced benefit vaccinating women at older ages. Although the rates of HPV infection declined dramatically with age, the subsequent CIN3+ risks associated with HPV infection declined only slightly. The CIN3+ risks among older women are sufficiently elevated to warrant continued screening through age 65. © 2014 UICC.

    To investigate time trends in overweight and Leisure Time Physical Activities (LTPA) in The Netherlands since 1980. Intra-national differences were examined stratified for sex, age and urbanisation degree. We used a random sample of about 140,000 respondents aged 20-69 years from the Health Interview Survey (Nethhis) and subsequent Permanent Survey on Living Conditions (POLS). Self-reported data on weight and height and demographic characteristics were gathered through interviews (every year) and data on LTPA were collected by self-administered questionnaires (1990-1997, 2001-2004). Linear regression analysis was performed for trend analyses. During 1981-2004, mean body mass index (BMI) increased significantly by 1.0 kg/m(2) (average per year=0.05 kg/m(2)). Trends were similar across sex and different degrees of urbanisation, but varied across age groups. In 20-to 39-year-old women, mean BMI increased by 1.7 kg/m(2), which was more than in older age groups (Page groups. During 2001-2004, 20-to 39-year-old women spent approximately 150 min/week less on LTPA compared to older women, while this difference was smaller during 1990-1997. Mean BMI increased more in younger women, which is consistent with the observation that this group spent less time on LTPA during recent years. Although the overall increase in overweight could not be explained by trends in LTPA, the younger women should be considered as a target group for future physical activity interventions. The influence of the 'obesogenic environment' seems to be similar across different degrees of urbanisation.

A consequence of strain localization in many tectonic settings that bear calcitic marbles is the formation of marble mylonites and ultramylonites. Little is known, however, about the behaviour of the K/Ar systems and the influence of deformation on the ages in such rocks. We studied an extremely localized shear zone (2 cm thick) in marble from Syros (Cyclades, Greece) and performed microstructural, chemical and isotopic analysis on samples from the host rock and the shear zone. The host rock is composed of coarse-grained (300 µm) calcite with only minor undulatory extinction and slightly curved grain boundaries. This initial large grain size is likely to have formed during the Eocene high-pressure - low-temperature event that is well documented in the Cyclades. In contrast, the marble within the shear zone shows evidence of strong intracrystalline deformation and recrystallization resulting in grain size reduction and the formation of an ultramylonite. Both microstructures and kinematics are consistent with the low grade evolution described on Syros. White mica (100's microns in size) are preferentially orientated parallel to the foliation. In both samples there is no clear evidence for crystal plastic deformation of the mica grains. Bigger grains behave brittle resulting in grain size reduction. A deformation mechanism map for calcite at 300 °C indicates that the host rock deformed at strain rates of around 10-12.5 s-1 whereas within the shear zone strain rates of up to 10-9.5 s-1 are attained. We performed laser-heating 40Ar/39Ar analysis on white mica located in the host rock and the shear zone. The low-strain host rock yielded a ca. 40 Ma age, and the shear zone recorded a ca. 37 Ma age; both ages are

    Metabolic syndrome (MetS) was common in the elderly, but its prognostic significance in older old population remained unclear. The main purpose of this study was to evaluate the survival impact of MetS among older men aged 75 and over in Taiwan. From 2008, residents aged 75 years and older of Banciao Veterans Home were invited for study and were followed for 3 years. All participants received history taking, physical examinations, and laboratory tests. Mortality was determined by Veteran Affairs Death Registry, which was linked to the National Death Registry. Overall, 680 men (mean age: 82.5±4.7 years) were enrolled for study and the prevalence of MetS was 31.6%. During the follow-up period, 140 (20.6%) participants died, and the causes of death included infectious diseases (62, 9.1%), cardiovascular disease (37, 5.4%), cancer (20, 2.9%), and others (21, 3.1%). MetS subjects had a significantly higher prevalence of hypertension, diabetes mellitus, and having higher body mass index, waist circumferences, systolic blood pressure, fasting blood glucose, serum triglyceride and lower HDL-C level than non-MetS subjects. However, MetS subjects were less likely to die during study period (16.3% vs. 22.6%, P=0.059). Multivariate logistic regression showed that older age (OR:1.04, 95% C.I.: 1.00-1.08, P=0.04), diabetes mellitus (OR: 2.10, 95% CI: 1.34-3.30, P=0.001) were independent risk factors for mortality; and serum total cholesterol and triglyceride were protective factors (OR: 0.99, 95% CI: 0.99-1.00, P=0.037 for cholesterol; OR: 0.99, 95% CI: 0.99-1.00, P=0.013 for triglyceride). Adjusted for age, diabetes mellitus, serum levels of total cholesterol, and triglyceride, MetS played a potential trend of survival benefits among study subjects (HR: 0.71, 95% CI: 0.45-1.12, P=0.144). The prevalence of MetS among men aged 75 years and over was 31.6%, and the 3-year mortality rate was 20.6%. Older age, diabetes mellitus, lower serum cholesterol and lower serum triglyceride

    The epidemiology and prognosis of chronic kidney disease (CKD) differ by sex. We aimed to compare symptom prevalence and the clinical state in women and men of ≥65 years of age with advanced CKD receiving routine nephrology care. The European QUALity study on treatment in advanced chronic kidney disease (EQUAL) study follows patients from six European countries of ≥65 years of ageyears whose estimated glomerular filtration rate (eGFR) dropped to ≤20 mL/min/1.73 m2 for the first time during the last 6 months. The Dialysis Symptom Index was used to assess the prevalence and severity of 33 uraemic symptoms. Data on the clinical state at baseline were collected from medical records. Prevalence was standardized using the age distribution of women as the reference. The results in women (n = 512) and men (n = 967) did not differ with age (77.0 versus 75.7 years) or eGFR (19.0 versus 18.5). The median number of symptoms was 14 [interquartile range (IQR) 9-19] in women, and 11 (IQR 7-16) in men. Women most frequently reported fatigue {39% [95% confidence interval (CI) 34-45]} and bone/joint pain [37% (95% CI 32-42)] as severe symptoms, whereas more men reported difficulty in becoming sexually aroused [32% (95% CI 28-35)] and a decreased interest in sex [31% (95% CI 28-35)]. Anaemia [73% (95% CI 69-77) versus 85% (95% CI 82-87)] was less common in women than in men, as were smoking history and cardiovascular comorbidity. However, a diagnosis of liver disease other than cirrhosis, psychiatric disease and mild malnutrition were more common among women. Women in secondary care with an incident eGFR ≤20 mL/min/1.73 m2 reported a higher symptom burden, while their clinical state was considered similar or even more favourable as compared with men.

    Objectives: To investigate long-term prospective associations between a range of measurements of hypertensive status in midlife and cognitive impairment 20 years later. Design: Cohort study. Setting: Two areas (Southall and Brent) of northwest London. Participants: Survey samples of a multiethnic population (European, African Caribbean, South Asian) aged 40 to 67 were followed up 20 years later. Measurements: Comprehensive cardiovascular assessments were performed at baseline, including measurements of resting blood pressure (BP) and, in a subsample, ambulatory BP. At follow-up, a battery of cognitive assessments was administered, and a composite outcome was derived, with impairment defined as the lowest 10% within each ethnic group. Logistic regression models were used to investigate associations with prior measures of hypertensive status. Results: In 1,484 participants at follow-up, cognitive impairment showed significant U-shaped associations with baseline diastolic BP (DBP) and mean arterial pressure (MAP; strongest for those aged ≥50 at baseline), independent of a range of covariates, but no associations were found with systolic BP or pulse pressure. Cognitive impairment was also associated with antihypertensive medication use and higher evening ambulatory DBP at baseline. No substantial differences in strengths of association were found between ethnic groups. Conclusion: Low and high DBP and MAP were associated with cognitive impairment 20 years later. Higher evening DBP on ambulatory monitoring was also associated with greater risk. PMID:24028355

    prescriptions was as follows: 40-49 years, 23%; 50-59 years, 35%; and 60-69 years, 25%. The past decade saw rises in heterosexual transmission of HIV and i.v. drug use, especially in the population aged >50 years. The CDC reports that the incidence of new HIV infection is stabilizing in men aged 30-39 years and even falling in men aged 20-29 years. Gonorrhea is well known to increase infectivity for HIV and other STDs. Although the rates of gonorrhea infection fell throughout the early 1990s, they increased by 9% between 1997 and 1999. The number of sildenafil prescriptions has increased by almost 80% over the last few years. Although there may be multiple contributory factors for these findings, to our knowledge this is the first paper in the urologic literature to examine such trends in the older male population, especially in the light of newly available medications for erectile dysfunction.

    To better understand the various individual factors that contribute to balance and the relation to fall risk, we performed the modified Romberg Test of Standing Balance on Firm and Compliant Support, with 1,174 participants between 4 and 83 years of age. This research was conducted in the Living Laboratory® at the Museum of Science, Boston. We specifically focus on balance test condition 4, in which individuals stand on memory foam with eyes closed, and must rely on their vestibular system; therefore, performance in this balance test condition provides a proxy for vestibular function. We looked for balance variations associated with sex, race/ethnicity, health factors, and age. We found that balance test performance was stable between 10 and 39years of age, with a slight increase in the failure rate for participants 4–9 years of age, suggesting a period of balance development in younger children. For participants 40 years and older, the balance test failure rate increased progressively with age. Diabetes and obesity are the two main health factors we found associated with poor balance, with test condition 4 failure rates of 57 and 19%, respectively. An increase in the odds of having fallen in the last year was associated with a decrease in the time to failure; once individuals dropped below a time to failure of 10 s, there was a significant 5.5-fold increase in the odds of having fallen in the last 12 months. These data alert us to screen for poor vestibular function in individuals 40 years and older or suffering from diabetes, in order to undertake the necessary diagnostic and rehabilitation measures, with a focus on reducing the morbidity and mortality of falls.

    Hearing impairment (HI) is one of the most common conditions affecting older adults. Identification of factors associated with the development of HI may lead to ways to reduce the incidence of this condition. To investigate the association between cystatin C, both as an independent biomarker and as a marker of kidney function, and the 20-year incidence of HI. Data were obtained from the Epidemiology of Hearing Loss Study (EHLS), a longitudinal, population-based study in Beaver Dam, Wisconsin. Baseline examinations began in 1993 and continued through 1995, and participants were examined approximately every 5 years, with the most recent examination phase completed in 2015. The EHLS participants with serum cystatin C concentration data and without HI at the baseline examination were included in this study. Participants without HI were followed up for incident HI (pure-tone average of hearing thresholds at 0.5, 1, 2, and 4 kHz >25 dB hearing level in either ear) for 20 years. Cystatin C was analyzed as a biomarker (concentration) and used to determine estimated glomerular filtration rate (eGFRCysC). Discrete-time Cox proportional hazards regression models were used to analyze the association between cystatin C concentration and eGFRCysC and the 20-year cumulative incidence of HI. There were 863 participants aged 48 to 86 years with cystatin C data and without HI at baseline. Of these, 599 (69.4%) were women. In models adjusted for age and sex, cystatin C was associated with an increased risk of developing HI (hazard ratio [HR], 1.20; 95% CI, 1.07-1.34 per 0.2-mg/L increase in cystatin C concentration), but the estimate was attenuated after further adjusting for educational level, current smoking, waist circumference, and glycated hemoglobin (HR, 1.11; 95% CI, 0.98-1.27 per 0.2-mg/L increase in cystatin C concentration). Low eGFRCysC was significantly associated with the 20-year cumulative incidence of HI in both the age- and sex-adjusted model (HR, 1.70; 95% CI, 1

    Zimbabwe aims to increase circumcision coverage to 80% among 13- to 29-year-olds. However, implementation data suggest that high coverage among men ages 20 and older may not be achievable without efforts specifically targeted to these men, incurring additional costs per circumcision. Scale-up scenarios were created based on trends in implementation data in Zimbabwe, and the cost-effectiveness of increasing efforts to recruit clients ages 20-29 was examined. Zimbabwe voluntary medical male circumcision (VMMC) program data were used to project trends in male circumcision coverage by age into the future. The projection informed a base scenario in which, by 2018, the country achieves 80% circumcision coverage among males ages 10-19 and lower levels of coverage among men above age 20. The Zimbabwe DMPPT 2.0 model was used to project costs and impacts, assuming a US$109 VMMC unit cost in the base scenario and a 3% discount rate. Two other scenarios assumed that the program could increase coverage among clients ages 20-29 with a corresponding increase in unit cost for these age groups. When circumcision coverage among men ages 20-29 is increased compared with a base scenario reflecting current implementation trends, fewer VMMCs are required to avert one infection. If more than 50% additional effort (reflected as multiplying the unit cost by >1.5) is required to double the increase in coverage among this age group compared with the base scenario, the cost per HIV infection averted is higher than in the base scenario. Although increased investment in recruiting VMMC clients ages 20-29 may lead to greater overall impact if recruitment efforts are successful, it may also lead to lower cost-effectiveness, depending on the cost of increasing recruitment. Programs should measure the relationship between increased effort and increased ability to attract this age group.

    Aging is associated with a decline in maximal aerobic capacity (VO 2max ) that may be attenuated by chronic endurance exercise. This case study chronicles the changes in marathon times in a 91 year old man who completed 627 marathons and 117 ultramarathons over 42 years. He began running marathons at age 48. His yearly best times remained fairly constant at ~240 minutes from age 50 - 64 years and then gradually rose to about 260 minutes in his early seventies followed by a curvilinear deterioration as he approached his ninth decade. His times plateaued at ~ 600 minutes in his late eighties. Between ages 68 and 89 his VO 2max declined from 43 to 20 ml/kg/min. His marathon times were highly correlated with his VO 2max (r 2 =0.87). The decline in marathons times and VO 2max may reflect the contributions of biological aging, changes in exercise training volume and intensity, injuries, and comorbid disease.

    On April 16, 1979, Massachusetts raised its legal drinking age from 18 to 20 years. Massachusetts was compared with New York State, exclusive of New York City and Nassau County. New York State retained an 18-year-old drinking age. Random telephone surveys with approximately 1,000 16-19 year olds in each state were undertaken prior to the law's enactment and twice at yearly intervals after the law to assess the law's impact on teenage drinking, driving after drinking, and non-fatal accident involvement. Fatal crash data reported to the US Department of Transportation by each state from April 16, 1976-April 15, 1981 were also analyzed. After the law, although the modes of procuring alcohol changed. No significant changes were observed in Massachusetts relative to New York in the proportion of surveyed teenagers who reported that they drank or in the volume of their consumption. The proportion of teenagers who drove after drinking heavily (six or more drinks at one time) did not decline in Massachusetts relative to New York. However, the frequency that teenagers reported driving after any drinking declined significantly in Massachusetts. Frequency of teenage driving after marijuana use and non-fatal teenage accidents declined at comparable rates in both states. The numbers of teenage nighttime single vehicle fatal accidents declined more in Massachusetts than New York, in the 18-19 year age group. Overall fatal accident trends among 16-19 year olds in the two states were similar.

    There is a well-known link between attending college and engaging in excessive alcohol use. This study examines in a national sample how the association between student status and excessive alcohol use changes from late adolescence through young adulthood and whether the association of student status with excessive alcohol use is different for students residing with versus away from parents during the school year. This study used cross-sectional data from the National Epidemiologic Survey on Alcohol and Related Conditions, a nationally representative sample of noninstitutionalized civilian adults residing in the United States. Our analyses included nonhigh school young adults who were ages 18 to 30 years (n = 8,645). Excessive alcohol use included past-year (i) high-intensity drinking (men: ≥10 standard drinks; women: ≥8) and (ii) exceeding weekly drinking guidelines (men: >14 drinks per week; women: >7). Students who resided away from their parents and students who lived with their parents during the school year were compared to nonstudents. Analyses using time-varying effect modeling showed that the relationship of student status with excessive alcohol use varied as a function of age. Overall student status lost its association with excessive alcohol use in the early 20s, after controlling for demographics and other adult social roles. The association between student status and excessive alcohol use also varied considerably across age and depending on whether the student was residing with or away from parents. The association of student status with excessive alcohol use is heterogeneous in terms of both age and living arrangements, suggesting opportunities for interventions targeting problematic alcohol use. Future research should examine additional sources of heterogeneity of students in their risk for excessive alcohol use. Copyright © 2016 by the Research Society on Alcoholism.

    Advanced maternal age is associated with labor dystocia (LD) in nulliparous women. This study investigates the age-related risk of LD in first, second and third births. All live singleton cephalic births at term (≥ 37 gestational weeks) recorded in the Swedish Medical Birth Register from 1999 to 2011, except elective cesarean sections and fourth births and more, in total 998 675 pregnancies, were included in the study. LD was defined by International Classification of Diseases, version 10 codes (O620, O621, O622, O629, O630, O631 and O639). In each parity group risks of LD at age 25-29 years, 30-34 years, 35-39 years and ≥ 40 years compared with age < 25 years were investigated by logistic regression analyses. Analyses were adjusted for year of delivery, education, country/region of birth, smoking in early pregnancy, maternal height, body mass index, week of gestation, fetal presentation and infant birthweight. Rates of LD were 22.5%, 6.1% and 4% in first, second and third births, respectively. Adjusted odd ratios (OR) for LD increased progressively from the youngest to the oldest age group, irrespective of parity. At age 35-39 years the adjusted OR (95% CI) was approximately doubled compared with age 25 and younger: 2.13 (2.06-2.20) in first birth; 2.05 (1.91-2.19) in second births; and 1.81 (1.49-2.21) in third births. Maternal age is an independent risk factor for LD in first, second and third births. Although age-related risks by parity are relatively similar, more nulliparous than parous women will be exposed to LD due to the higher rate. © 2017 Nordic Federation of Societies of Obstetrics and Gynecology.

    This study investigated cancer portrayals in newspapers now and 20 years ago. Six major daily newspapers from regions across Canada were studied. All articles from a 3-month period in 2008 (n = 576) and 1988 or 1989 (n = 412) focusing on cancer were analyzed. Cancer is a more prevalent topic and is depicted in a more positive light in newspapers now when compared to 20 years ago. In 2008, the most common cancer-related themes were cancer research (27%), risk factors (26%), treatment (24%), education/prevention (20%), and fundraising events (19%). Compared to 1988/1989, in 2008, there was a significant decrease in articles covering the end of life and surgery, while there was a significant increase in articles portraying the senior population, male issues, individual stories depicting people suffering from cancer, the health care system, fundraising events, and ethics and law. The percentage of articles on psychosocial aspects of the cancer experience remained the same in 1988/1989 compared with 2008, with 16% of articles covering psychological aspects (vs. 17% in 2008), 5.6% social aspects (vs. 3.9% in 2008), and 0.2% spiritual aspects (vs. 0.5% in 2008). In 2008, few cancer articles spoke in-depth about palliative care (2.8%), issues concerning death and dying (5%), or bereavement (1%). Cancer newspaper reporting mostly focuses on the physical aspects of cancer rather than presenting a more holistic approach including psychosocial issues. Implications of the shifts in tone and content of newspaper reporting are discussed. We highlight the importance of promoting coverage of distress as the sixth vital sign in newspaper press so as to inform readers about the experience of cancer and the existence of psychosocial services designed to optimize quality of life.

    This article presents high, medium, and low variants of projections for China's population aged 0-14 years, 15-59 years, over 60 years, over 65 years, and over 80 years. Projections are based on data from the 1990 Census and the 1995 1% sample survey. China's population is expected to reach 1.281 billion in 2000, and 1.666 billion in 2050, under the high variant; 1.271 billion in 2000, and 1.535 billion in 2040, under the medium variant; and 1.261 billion in 2000, 1.442 billion in 2030, and declining to 1.346 billion by 2050, under the low variant. Decreases will not occur under the medium variant until 2050, to 1.507 billion. The total fertility rate is expected to decline from 2.3 in 2000, to 2.0 before 2050, under the high variant; from 2.0 in 2000, to 1.8 before 2050, under the medium variant; and 1.8 in 2000, to 1.6 before 2050, under the low variant. By 2050, the average life expectancy is expected to increase to 75 years for males and 79 years for females. The death rate will decline from 7% at present to 6.8% in 2000, and then increase to 14% by 2050. The total dependency ratio will decrease from 56.92% in 2000, to 53.53% in 2010, and then increase to 72.46% in 2050, under the high variant. The child dependency ratio will decline from 41.13% in 2000, to 32.19% in 2050. The aged dependency ratio will rise from 15.79% in 2000, to 40.27% in 2050. The aged-child ratio will increase from 38.39% in 2000, to 125.08% in 2050.

    There is limited evidence on how diet changes over the transition from primary to secondary school. In this study we investigated changes in diet from age 10 (2007) to age 14 years (2011) and the contribution of school-time consumption and school lunch choice to such changes. The 351 participants with dietary data (4 day food record) available at baseline (age 10 years) and follow-up (age 14 years) were included. Multi-level regression models were fitted for absolute or change in food and nutrient intake, cross-classified by primary and secondary school attended as appropriate, with adjustment for covariates and mis-reporting. From age 10 to age 14 years, children decreased energy intake from sugars (-2.6% energy (%E)) (standard error (SE) 0.44) and from saturated fats (-0.54%E (SE 0.18)), decreased fruit (-3.13 g/MJ (SE 1.04)) and vegetables (-1.55 g/MJ (SE 0.46)) consumption and increased sugar sweetened beverage (SSB) (4.66  g/MJ (SE 1.87)) and fries (1.31  g/MJ (SE 0.39)) consumption. Intake of snack foods, SSBs, and fries, but also fruits and vegetables was higher outside school hours. Prospective change from non-school lunch to school lunch, compared to maintaining non-school lunch consumption, was associated with decreased consumption of savoury snacks (-8.32 g/day (SE 2.03)), increased consumption of fries (12.8 g/day (SE 4.01)) and decreased consumption of fruit (-25.16 g/day (SE 11.02)) during school hours. Changes in diet from age 10 to age 14 years differed within and outside of school hours. Consumption of a school lunch, compared to lunch obtained elsewhere, was associated with negative as well as positive changes in diet, suggesting that any efforts to encourage school lunch take-up need to be accompanied by further efforts to improve school lunch provision to meet nutritional guidelines.

    To identify postnatal predictors of malnutrition among 7- to 10-year-old children and to assess the long-term effects of antenatal micronutrient supplementation on malnutrition. A follow-up study was conducted to assess the nutritional status of 7- to 10-year-olds (1747 children) whose mothers participated in a cluster-randomized double-blind controlled trial from 2002 to 2006. The rate of malnourished 7- to 10-year-olds was 11.1%. A mixed-effects logistic regression model adjusted for the cluster-sampling design indicated that mothers with low prepregnant midupper arm circumference had boys with an increased risk of thinness (aOR  2.05, 95% CI  1.11, 3.79) and girls who were more likely to be underweight (aOR 2.01, 95% CI 1.05, 3.85). Antenatal micronutrient supplementation was not significantly associated with malnutrition. Low birth weight was significantly associated with increased odds of malnutrition among boys (aOR 4.34, 95% CI 1.82, 10.39) and girls (aOR  7.50, 95% CI 3.48, 16.13). Being small for gestational age significantly increased the odds of malnutrition among boys (aOR 1.75, 95% CI 1.01, 3.04) and girls (aOR 4.20, 95% CI  2.39, 7.39). In addition, household wealth, parental height, being picky eater, and illness frequency also predicted malnutrition. Both maternal prenatal nutrition and adverse birth outcomes are strong predictors of malnutrition among early school-aged children. Currently, available evidence is insufficient to support long-term effects of antenatal micronutrient supplementation on children's nutrition. www.isrctn.com: ISRCTN08850194.

    To study whether walking limitation at old age is determined by obesity history. In a retrospective longitudinal study based on a representative sample of the Finnish population of 55 years and older (2055 women and 1337 men), maximal walking speed, body mass, and body height were measured in a health examination. Walking limitation was defined as walking speed<1.2 m/s or difficulty in walking 0.5 km. Recalled height at 20 years of age and recalled weight at 20, 30, 40, and 50 years of age were recorded. Subjects who had been obese at the age of 30, 40, or 50 years had almost a 4-fold higher risk of walking limitation compared to non-obese. Obesity duration increased the age- and gender-adjusted risk of walking limitation among those who had been obese since the age of 50 (odds ratio, 4.33; 95% confidence interval, 2.59 to 7.23, n=114), among the obese since the age of 40 [6.01 (2.55 to 14.14), n=39], and among the obese since the age of 30 [8.97 (3.06 to 26.29), n=14]. The risk remained elevated even among those who had previously been obese but lost weight during their midlife or late adulthood [3.15 (1.63 to 6.11), n=71]. Early onset of obesity and obesity duration increased the risk of walking limitation, and the effect was only partially mediated through current BMI and higher risk of obesity-related diseases. Preventing excess weight gain throughout one's life course is an important goal in order to promote good health and functioning in older age.

  14. Prospective evaluation of respiratory exacerbations in children with cystic fibrosis from newborn screening to 5 years of age.

    Newborn screening allows novel treatments for cystic fibrosis (CF) to be trialled in early childhood before irreversible lung injury occurs. As respiratory exacerbations are a potential trial outcome variable, we determined their rate, duration and clinical features in preschool children with CF; and whether they were associated with growth, lung structure and function at age 5 years. Respiratory exacerbations were recorded prospectively in Australasian CF Bronchoalveolar Lavage trial subjects from enrolment after newborn screening to age 5 years, when all participants underwent clinical assessment, chest CT scans and spirometry. 168 children (88 boys) experienced 2080 exacerbations, at an average rate of 3.66 exacerbations per person-year; 80.1% were community managed and 19.9% required hospital admission. There was an average increase in exacerbation rate of 9% (95% CI 4% to 14%; p<0.001) per year of age. Exacerbation rate differed by site (p<0.001) and was 26% lower (95% CI 12% to 38%) in children receiving 12 months of prophylactic antibiotics. The rate of exacerbations in the first 2 years was associated with reduced forced expiratory volume in 1 s z scores. Ever having a hospital-managed exacerbation was associated with bronchiectasis (OR 2.67, 95% CI 1.13 to 6.31) in chest CT scans, and lower weight z scores at 5 years of age (coefficient -0.39, 95% CI -0.74 to -0.05). Respiratory exacerbations in young children are markers for progressive CF lung disease and are potential trial outcome measures for novel treatments in this age group.

    In order to understand the risk of polybrominated diphenyl ethers (PBDEs) existing in sediment for years, the accumulation of PBDEs in sediment aged for 2 years to fish was investigated. Simulated aquatic system microcosms were conducted with PBDE contaminated sediment aged for 2 years and carps were cultured in the microcosms for 20 days. PBDE concentrations in carp tissues were analyzed to estimate the bioavailability of aged PBDEs in carps. The main spiked PBDE congeners were detected in sediment even though the contaminated sediment was aged for 2 years. Similarly, the five PBDE (BDE-28, 47, 100, 153 and 154) congeners which probably were bioaccumulated by carp were detected in fish tissues, indicating that PBDEs could be bioaccumulated after aging for 2 years. The PBDEs distribution revealed that the concentrations of polybrominated diphenyl ethers in tissues of Cyprinus carpio is in this order of magnitude: gut > liver > gill > fillet. The PBDEs concentrations in fillet were as high as 67.9 ng/g dry wt, in which BDE-47 contributed almost 50% in profile.

  16. Can cerebral MRI at age 1 year predict motor and intellectual outcomes in very-low-birthweight children?

    This follow-up study reports on cerebral MRI findings in 20 very-low-birthweight (VLBW) infants without disabilities at age 1 year in relation to motor, intellectual, and perceptual function at age 6 years. MRI findings, anthropometrics, and Bayley Scales of Infant Development scores at age 1 year as predictors of psychomotor status at age 6 years are also evaluated and compared. Outcome parameters were the Peabody Developmental Motor Scales and the Wechsler Preschool and Primary Scale of Intelligence. The results show that infants with myelin hyperintensities including the centrum semiovale or with occipital hyperintensities with associated ventricular dilatation at age 1 scored lower on the Peabody Gross Motor Locomotion Scale at age 6 than infants with normal myelination or with isolated occipital hyperintensities. This may indicate damage to motor fibers caused by perinatal periventricular leukomalacia. No relation was found between abnormal MRI findings at age 1 and later fine motor, intellectual, and perceptual function. Comparing different age 1-year predictors, an abnormality score defined by MRI was used as an independent predictor of gross motor locomotion function at age 6 years. However, the Bayley Mental Development Index scores and weight at age 1 were more important predictors of later motor and intellectual outcome, respectively, than MRI findings. It is recommended that cerebral MRI should not be used routinely to examine VLBW infants without disabilities at 1 year of age.

    2013-01-01

    Young adults in the USA have one of the highest smoking prevalence rates of any age group, and young adulthood is a critical time period of targeting by the tobacco industry. The authors examined relationships between potential exposure to tobacco-related media campaigns from a variety of sponsors and 2-year smoking change measures among a longitudinal sample of US adults aged 20-30 years from 2001 to 2008. Self-report data were collected from a longitudinal sample of 12,931 US young adults from age 20 to 30. These data were merged with tobacco-related advertising exposure data from Nielsen Media Research. Two-year measures of change in smoking were regressed on advertising exposures. Two-year smoking uptake was unrelated to advertising exposure. The odds of quitting among all smokers and reduction among daily smokers in the 2 years between the prior and current survey were positively related to anti-tobacco advertising, especially potential exposure levels of 104-155 ads over the past 24 months. Tobacco company advertising (including corporate image and anti-smoking) and pharmaceutical industry advertising were unrelated to quitting or reduction. Continued support for sustained, public health-based well-funded anti-tobacco media campaigns may help reduce tobacco use among young adults.

    The incidence of primary systemic vasculitides varies among different geographic regions and ethnic origins. The aim of this study was to examine the incidence rates of vasculitides in the Jerusalem Jewish population, and to examine possible trends in incidence rates over a 20-year period. The clinical databases of inpatients at the 2 medical centers in Jerusalem were searched for patients with vasculitis diagnosed between 1990-2009. Individual records were then reviewed by one of the authors. The significance of trends in incidence rates throughout the study period was evaluated by Pearson correlation coefficient. The average annual incidence rate of polyarteritis nodosa was 3.6/million adults (95% CI 1.6-4.7). Incidence rates did not change significantly during this period (r = 0.39, p = 0.088). The incidence of granulomatosis with polyangiitis (GPA) was 4.1 (2.2-5.9) for the whole period, during which it increased significantly (r = 0.53, p < 0.05). The incidence of microscopic polyangiitis (MPA) was lower: 2.3 (1.2-3.5)/million. It also increased significantly (r = 0.55, p < 0.05). The incidence of eosinophilic granulomatosis with polyangiitis was 1.2 (0.4-1.9), which remained stable throughout the study period. The incidence of Takayasu arteritis was 2.1/million (95% CI 1.2-2.9), and it also remained stable. Giant cell arteritis (GCA) incidence was 8.1 (5.7-10.6)/100,000 population aged 50 years or older. In sharp contrast with other vasculitides, its incidence decreased significantly throughout the study period (r = -0.61, p < 0.01). The incidence rates of vasculitides in the Jewish population of Jerusalem are in the lower range of global incidence rates. While GPA and MPA incidence are increasing, GCA incidence is decreasing.

    This qualitative study identified four life trajectories that influenced the decision in young women to have genetic testing for mutations in BRCA1/2 and subsequent risk reduction decisions after receiving a positive mutation result. Fifty nine women between the ages of 18–39 years were interviewed in this grounded theory study, 44 of those tested were found to have a mutation in either BRCA1 or BRCA2. Of those with a mutation, 23 had no history of cancer and 21 had a breast cancer diagnosis. Analysis of the 44 participants tested found that risk reducing decisions were related to the life trajectories that preceded genetic testing. These life trajectories included: 1) Long-standing awareness of breast cancer in the family, 2) Loss of one’s mother to breast cancer at a young age, 3) Expression of concern by a health care provider, and 4) Personal diagnosis of breast cancer. Understanding possible influences behind decision making for genetic testing and risk reduction in young women may assist health care providers in offering age appropriate guidance and support.

    As part of a risk-management approach, sound epidemiological data are needed to develop prevention programs. A recent review on soccer injuries of players younger than 19 years concluded that prospective data concerning children are lacking. To analyze the incidence and characteristics of soccer injuries in children aged 7 to 12 years. Descriptive epidemiological study. The present survey was a prospective descriptive epidemiological study on soccer injuries over 2 seasons in the Czech Republic and Switzerland. Exposure of players during training and match play (in hours) and injury data were reported by coaches via an Internet-based registration system. Location, type, and severity of injuries were classified according to an established consensus. Injury characteristics are presented as absolute numbers and injury incidence rates (injuries per 1000 hours of soccer exposure). An injury was defined as any physical complaint sustained during a scheduled training session or match play resulting in at least 1 of the following: (1) inability to complete the current match or training session, (2) absence from subsequent training sessions or matches, and (3) injury requiring medical attention. In total, 6038 player-seasons with 395,295 hours of soccer exposure were recorded. The mean (±SD) age of the players was 9.5 ± 2.0 years, and 3.9% of the participants were girls. A total of 417 injuries were reported. Most (76.3%) injuries were located in the lower limbs, with 15.6% located in the upper limbs. Joint and ligament injuries comprised 30.5%, contusions 22.5%, muscle and tendon injuries 18.5%, and fractures and bone injuries 15.4% of all injuries; 23.7% of injuries led to more than 28 days of absence from sport participation. The overall injury incidence was 0.61 (95% CI, 0.53-0.69) injuries per 1000 hours of soccer exposure during training sessions and 4.57 (95% CI, 4.00-5.23) during match play. Injury incidence rates increased with increasing age. The observed injury

    Scholars argue about whether age stereotypes (beliefs about old people) are becoming more negative or positive over time. No previous study has systematically tested the trend of age stereotypes over more than 20 years, due to lack of suitable data. Our aim was to fill this gap by investigating whether age stereotypes have changed over the last two centuries and, if so, what may be associated with this change. We hypothesized that age stereotypes have increased in negativity due, in part, to the increasing medicalization of aging. This study applied computational linguistics to the recently compiled Corpus of Historical American English (COHA), a database of 400 million words that includes a range of printed sources from 1810 to 2009. After generating a comprehensive list of synonyms for the term elderly for these years from two historical thesauri, we identified 100 collocates (words that co-occurred most frequently with these synonyms) for each of the 20 decades. Inclusion criteria for the collocates were: (1) appeared within four words of the elderly synonym, (2) referred to an old person, and (3) had a stronger association with the elderly synonym than other words appearing in the database for that decade. This yielded 13,100 collocates that were rated for negativity and medicalization. We found that age stereotypes have become more negative in a linear way over 200 years. In 1880, age stereotypes switched from being positive to being negative. In addition, support was found for two potential explanations. Medicalization of aging and the growing proportion of the population over the age of 65 were both significantly associated with the increase in negative age stereotypes. The upward trajectory of age-stereotype negativity makes a case for remedial action on a societal level. PMID:25675438

    Namibia experienced a large measles outbreak starting in 2009, with 38% of reported cases in adults, including women of reproductive age. Population immunity was assessed among pregnant women to determine whether immunization activities were needed in adults to achieve measles elimination in Namibia. A total of 1708 and 2040 specimens sampled from Namibian pregnant women aged 15-44 years who were included in the 2008 and 2010 National HIV Sentinel Survey, respectively, were tested for measles immunoglobulin G antibody. The proportion of women seropositive overall and by 5-year age strata was determined, and factors associated with seropositivity were analyzed by logistic regression, including age, facility type, gravidity, HIV status, and urban/rural setting. Seropositivity in 2008 versus 2010 was compared. In both analysis years, measles seropositivity was lower in 15-19-year-olds (77%) and 20-24-year-olds (85-87%) and higher in 25-44-year-olds (90-94%) (2008, p<0.001; 2010, p<0.001). Overall measles seropositivity did not differ between 2008 (87%) and 2010 (87%) (p=0.7). HIV status did not affect seropositivity. Late in a large measles outbreak, 13% of pregnant women in Namibia, and almost one in four 15-19-year-old pregnant women, remained susceptible to measles. In Namibia, immunization campaigns with measles-containing vaccine should be considered for adults. Published by Elsevier Ltd.

    The purpose of the present study was to identify changes in different components of physical capacity among middle-aged women and men employed in the municipal branch for 16 years. The data were obtained by laboratory measurements and postal questionnaires. The study group consisted of 45 middle-aged subjects, who were on average 51.5 years old at the beginning of the follow-up in 1981 and 67.3 years in 1997. During the 16-year follow-up period, the average physical capacity of these workers decreased by approximately 20%. The study showed that the greatest changes occurred in isometric trunk muscle strength and in the flexibility of the spine, whereas smaller changes were noted in anthropometrics. The decrease of physical capacity was greater among men (range 11.6% to 33.7%) than among women (range 3.3% to 26.7%), although women had more individual variations. On average, people without disease or who were physically active displayed better physical capacity than people with disease or who were physically passive.

    Advanced maternal age is associated with higher frequencies of antenatal and perinatal conditions, as well as a higher risk of cerebral palsy in offspring. We explore the association between maternal age and specific cerebral palsy risk factors. Data were extracted from the Canadian Cerebral Palsy Registry. Maternal age was categorized as ≥35 years of age and less than 20 years of age at the time of birth. Chi-square and multivariate logistic regressions were performed to calculate odds ratios and their 95% confidence intervals. The final sample consisted of 1391 children with cerebral palsy, with 19% of children having mothers aged 35 or older and 4% of children having mothers below the age of 20. Univariate analyses showed that mothers aged 35 or older were more likely to have gestational diabetes (odds ratio 1.9, 95% confidence interval 1.3 to 2.8), to have a history of miscarriage (odds ratio 1.8, 95% confidence interval 1.3 to 2.4), to have undergone fertility treatments (odds ratio 2.4, 95% confidence interval 1.5 to 3.9), and to have delivered by Caesarean section (odds ratio 1.6, 95% confidence interval 1.2 to 2.2). These findings were supported by multivariate analyses. Children with mothers below the age of 20 were more likely to have a congenital malformation (odds ratio 2.4, 95% confidence interval 1.4 to 4.2), which is also supported by multivariate analysis. The risk factor profiles of children with cerebral palsy vary by maternal age. Future studies are warranted to further our understanding of the compound causal pathways leading to cerebral palsy and the observed greater prevalence of cerebral palsy with increasing maternal age.

    In women aged ≥30 years, Human Papillomavirus testing will replace cytology for primary cervical screening. We compared Hybrid Capture 2 (HC2), cobas, CLART, and APTIMA HPV assays with cytology on 2869 SurePath samples from women undergoing routine screening at 30–65 years in Copenhagen, Denmark. Women with cytological abnormalities were managed according to routine recommendations, with 92% completeness. Those with cytology-normal/HPV-positive samples (on any of the four assays) were invited for repeated cytology and HPV testing in 1.5 year, and 58% had additional testing. HPV testing detected more ≥CIN3 than cytology (HC2: 35, cobas, CLART: 37, APTIMA: 34, cytology: 31), although statistically the differences were not significant. Cobas and CLART detected significantly more ≥CIN2 than cytology (cobas, CLART: 49, cytology: 39). The proportion of women with false-positive test results (positive test results without ≥CIN3) varied between 3.3% with cytology and 14.9% with cobas. All HPV assays led to significantly more false-positive tests, whereas compared to HC2 cobas and CLART were associated with a significantly higher and APTIMA with a significantly lower proportion. Detection of CIN1 was particularly increased for the three DNA assays. With APTIMA combined with cytological triage, about 20% more women were referred for colposcopy than with cytology screening. With the three DNA assays, the increase was ≥50%. The number of women with repeated testing was twice as high with APTIMA and almost five times as high with cobas compared to cytology. To our knowledge, Horizon was the only study set in routine practice that compared more than two HPV assays in the same women while also ascertaining the histological status of women with normal cytology/HPV-positive test results. HPV-based screening of Danish women aged 30–65 detected more high-grade CIN but decreased the screening specificity, and increased the demand for additional testing. PMID:26789267

    Salivary duct carcinoma is a rare, aggressive malignancy of the salivary glands. Owing to its rare nature, clinical data are limited, and only a few clinical studies comprise more than 50 patients. To review the University of Pittsburgh Medical Center's experience with salivary duct carcinoma over a 20-year period, focusing on demographics, presentation, treatment, and outcome. This investigation was a retrospective cohort study in a multihospital institution with tertiary referral. A pathology database was reviewed for all cases of histopathologically diagnosed salivary duct carcinoma from January 1, 1995, to October 20, 2014. Patients who were referrals for pathology review only and were never seen at the institution were excluded. In total, 75 study patients were identified. The electronic medical record was reviewed for details regarding demographics, presentation, treatment, and outcome, including overall survival (OS) and disease-free survival (DFS). This study was supplemented with a review of the institution's Head and Neck Oncology Database for further clinical details. Primary outcome measures consisted of OS and DFS. The study sample comprised 75 participants with a mean age at diagnosis of 66.0 years (age range, 33-93 years), and 29% (n = 22) were female. Most primary tumors were from the parotid gland (83%), with the next most frequent site being the submandibular gland (12%). Overall, 41% of the cases were carcinoma ex pleomorphic adenoma. Rates of other histologic features included the following: perineural invasion (69%), extracapsular spread (58%), ERBB2 (formerly HER2) positivity (31%) (62% of those who were tested), and vascular invasion (61%). The median OS was 3.1 years, and the median DFS was 2.7 years. Univariate Kaplan-Meier survival analyses demonstrated that facial nerve sacrifice and extracapsular spread were associated with lower OS (2.38 vs 5.11 years and 2.29 vs 6.56 years, respectively) and DFS (2.4 vs 3.88 years and 1.44 vs 4

    We compared the outcomes of multiple myeloma (MM) patients aged 21-40 and 41-60 years in the novel agent era. This case-control study included 1089 patients between 2000 and 2015. Cases and controls were matched for sex, International Staging System (ISS) stage and institution. There were 173 patients in the younger group and 916 patients in the older group. Younger patients presented with a higher incidence of lytic lesions (82% vs. 72%; P = 0·04) and high-risk cytogenetic abnormalities (83% vs. 68%; P = 0·007), but lower rate of elevated lactate dehydrogenase (21% vs. 44%; P < 0·001). Five- and 10-year overall survival (OS) in younger versus older patients was 83% vs. 67% and 56% vs. 39%, respectively (P < 0·001). Similar results were seen when studying the subset of 780 patients who underwent autologous transplantation. Younger patients with ISS stage 1 had a better OS than older patients (P < 0·001). There was no survival difference between younger and older patients with ISS stage 2 or 3. Younger MM patients, aged 21-40 years, treated in the era of novel agents have a better OS than their counterparts aged 41-60 years, but the survival advantage observed in younger patients was lost in more advanced stages of MM. © 2016 John Wiley & Sons Ltd.

    In this study we systematically explore how acid leaching can be used to reduce the negative effects of seawater alteration on the 40Ar/39Ar age dating of submarine basalts. Koppers et al (2000) showed that acid leaching of groundmass samples generated more consistent ages as well as ages more concordant with phenocrystic mineral phases, compared to samples that were left untreated. By studying the effects of progressively increasing the strength and length of acid treatment, we will show how acid leaching of groundmass separates reduces alteration while leaving the initial eruption signature intact. Samples were chosen from the Walvis ridge hotspot trail in the southeast Atlantic. Three samples were selected based on degree and style of alteration. Two samples (basalt and basaltic andesite) appear highly altered in thin section. The basalt contains diffuse iddingsite alteration that is pervasive throughout the groundmass. The basaltic andesite displays focused secondary mineral phases within and around abundant vesicles. The third sample, a trachyte, shows relatively minor degrees of alteration in thin section. These groundmass separates were divided into four splits and treated with a progressively stronger acid and for longer duration. One split from each rock was left untreated to act as a baseline. Of the other three splits from each sample, one was treated with a mild leach (1N HCl and 1N HNO3), one a strong leach (1N HCl, 1N HNO3, 6N HCl, and 3N HNO3), and lastly the strong leach performed twice. The samples were then handpicked to remove any remaining visible alteration. The untreated samples were picked as well, removing the most distinctly altered grains. All splits were analyzed by electron microprobe, x-ray fluorescence (XRF) and the incremental heating 40Ar/39Ar dating method. We will report on the results of an image analysis of microprobe backscatter images and elemental maps taken of individual groundmass grains. This analysis will show the location

    Our objective was to determine scores on tests of neurocognitive functioning in children diagnosed with diabetes before age 10 years and to determine the association of age of diagnosis, duration of diabetes, subtle hypoglycemia, severe hypoglycemia, and history of hypoglycemic seizures with these neurocognitive test scores. Fifty-five of 62 eligible patients with a mean age of 7.9 +/- 1.6 years followed in our center were given the Woodcock-Johnson Psychoeducational Battery, Beery Developmental Test of Visual-Motor Integration, Finger Tapping, Grooved Pegboard, and Verbal Selective Reminding tests to evaluate the following domains: memory/attention, visual-perceptual, broad cognitive function, academic achievement, and fine motor speed/coordination. Fifteen age-matched siblings served as controls. Twenty-seven subjects were less than 5 years of age when diagnosed with diabetes, the mean age at diagnosis was 4.5 +/- 2.1 years of age, and mean diabetes duration was 2.6 +/- 2.0 years. Eighteen patients had a history of severe hypoglycemia, eight of whom had hypoglycemic seizures. The mean HbA1c was 7.8 +/- 1.1% for the year prior to testing. Our results showed that the overall mean scores for the extensive neurocognitive battery were within the normal range and were comparable to the scores of the age-matched sibling controls. Age of diagnosis and duration of diabetes did not relate to neurocognitive test results. Mean HbA1c had a negative association with some tests of memory/attention (p < 0.03-0.04) and academic achievement (p < 0.005-0.03), while number of blood glucose levels less than mg/dL had a positive association with memory/attention (p < 0.004-0.04), verbal comprehension (p < 0.03) and academic achievement (p < 0.018-0.05). There was no association of neurocognitive test scores with severe hypoglycemia, but subjects with history of hypoglycemic seizures had a decrease in scores on tests assessing memory skills (p < 0.03) including short term memory and

  14. 40Ar/39Ar geochronology of terrestrial pyroxene

    Geochronological techniques such as U/Pb in zircon and baddeleyite and 40Ar/39Ar on a vast range of minerals, including sanidine, plagioclase, and biotite, provide means to date an array of different geologic processes. Many of these minerals, however, are not always present in a given rock, or can be altered by secondary processes (e.g. plagioclase in mafic rocks) limiting our ability to derive an isotopic age. Pyroxene is a primary rock forming mineral for both mafic and ultramafic rocks and is resistant to alteration process but attempts to date this phase with 40Ar/39Ar has been met with little success so far. In this study, we analyzed pyroxene crystals from two different Large Igneous Provinces using a multi-collector noble gas mass spectrometer (ARGUS VI) since those machines have been shown to significantly improve analytical precision compared to the previous single-collector instruments. We obtain geologically meaningful and relatively precise 40Ar/39Ar plateau ages ranging from 184.6 ± 3.9 to 182.4 ± 0.8 Ma (2σ uncertainties of ±1.8-0.4%) and 506.3 ± 3.4 Ma for Tasmanian and Kalkarindji dolerites, respectively. Those data are indistinguishable from new and/or published U-Pb and 40Ar/39Ar plagioclase ages showing that 40Ar/39Ar dating of pyroxene is a suitable geochronological tool. Scrutinizing the analytical results of the pyroxene analyses as well as comparing them to the analytical result from plagioclase of the same samples indicate pure pyroxene was dated. Numerical models of argon diffusion in plagioclase and pyroxene support these observations. However, we found that the viability of 40Ar/39Ar dating approach of pyroxene can be affected by irradiation-induced recoil redistribution between thin pyroxene exsolution lamellae and the main pyroxene crystal, hence requiring careful petrographic observations before analysis. Finally, diffusion modeling show that 40Ar/39Ar of pyroxene can be used as a powerful tool to date the formation age of mafic

    The aim of this study was to investigate the effect of the use of nutrition labeling on nutritional intake according to age groups, focusing on Korean elderly. Study participants (N = 5223) were adults at least 20 y of age and had participated in the Korean National Health Examination and Nutrition Survey in 2012. Data for recognition/use of nutrition labels were obtained by self-report. Nutrition intake also was estimated by 24-h dietary recall. Participants were categorized into three age groups: 20 to 39 y, 40 to 59 y, and ≥60 y. Generalized linear model was conducted to test mean differences between nutrition label recognition (NLR) and nutrition label use (NLU) groups for nutrient intake, according to the age groups. Results from this study indicated that younger individuals (age groups of 20-39 and 40-59 y) in the NLU group showed a significant association with nutrient intake compared to those in the NLR group. Additionally, nutrition intake status in the NLU group improved positively. Whereas older participants (≥60 y) in the NLR group showed a significant association with most nutrient intake compared with the NLU group. The study also found that protein intake was reduced in the NLU group compared with the non-NLU group across the age groups, except for older participants (age group 20-39 y: 79.16 versus 86.30 g, P = 0.050; age group 40-59 y: 69.97 versus 75.58 g, P = 0.040; age group of ≥60 y: 64.72 versus 64.89 g, P = 0.967). The present study revealed that nutrition labeling cannot be effective for the elderly, and there were several areas of misunderstanding. Therefore, more systematic education on the topic of nutrition labeling is required to help the elderly make healthier food decisions. Copyright © 2016 Elsevier Inc. All rights reserved.

    The Wisconsin Diabetes Registry Study is a Wisconsin cohort of patients with type 1 diabetes, who were diagnosed in 1987-1992 and actively followed. The study provides patients and health care professionals with better prognostic information and helps identify aspects of diabetes management that need improvement. To describe diabetes management and acute and chronic complications from the time of diagnosis. All incident cases diagnosed at age <30 in 28 counties were eligible and 590 enrolled. A baseline interview, blood sample kits, biannual/annual questionnaires and study examinations at 4, 7, 9, 14, and 20 years duration were administered. Diabetes management indicators, general health, and acute and chronic complications. Glycemic control was poor in adolescence, but improved with age. A high percentage of individuals do not meet treatment standards for blood pressure and lipid profile. Self-reported health deteriorated with age, and body mass index was similar to that of the general US population. Chronic complications were present at 15-20 years, but tended to be relatively mild. There is room for improvement in diabetes management, especially in meeting goals for blood pressure and lipid profile. Nonetheless, individuals with type 1 diabetes can be offered a more optimistic prognosis than in the past.

    Gender dysphoria is a mismatch between a person's biological sex and gender identity. The best treatment is believed to be hormonal therapy and gender-confirming surgery that will transition the individual toward the desired gender. Treatment in Denmark is covered by public health care, and gender-confirming surgery in Denmark is centralized at a single-center with few specialized plastic surgeons conducting top surgery (mastectomy or breast augmentation) and bottom surgery (vaginoplasty or phalloplasty and metoidioplasty). To report the first nationwide single-center review on transsexual patients in Denmark undergoing gender-confirming surgery performed by a single surgical team and to assess whether age at time of gender-confirming surgery decreased during a 20-year period. Electronic patient databases were used to identify patients diagnosed with gender identity disorders from January 1994 through March 2015. Patients were excluded from the study if they were pseudohermaphrodites or if their gender was not reported. Gender distribution, age trends, and surgeries performed for Danish patients who underwent gender-confirming surgery. One hundred fifty-eight patients referred for gender-confirming surgery were included. Fifty-five cases (35%) were male-to-female (MtF) and 103 (65%) were female-to-male (FtM). In total, 126 gender-confirming surgeries were performed. For FtM cases, top surgery (mastectomy) was conducted in 62 patients and bottom surgery (phalloplasty and metoidioplasty) was conducted in 17 patients. For MtF cases, 45 underwent bottom surgery (vaginoplasty), 2 of whom received breast augmentation. The FtM:MtF ratio of the referred patients was 1.9:1. The median age at the time of surgery decreased from 40 to 27 years during the 20-year period. Gender-confirming surgery was performed on 65 FtM and 40 MtF cases at our hospital, and 21 transsexuals underwent surgery abroad. Mastectomy was performed in 62 FtM and bottom surgery in 17 FtM cases
