  1. Age of initiation of collision between India and Asia: A review of stratigraphic data

    NASA Astrophysics Data System (ADS)

    Rowley, David B.

    1996-12-01

    The collision of India with Asia is perhaps the most profound tectonic event to have occurred in past 100 Ma. It is responsible for the uplift of the Himalayas and Tibetan Plateau and has been argued to have been responsible for geological, geochemical, and climatological consequences of global extent. Yet the age of initiation of this collision remains poorly constrained. The literature is replete with estimates that range from the Late Cretaceous (> 65 Ma) to latest Eocene (< 40 Ma) with little consensus in between. This paper reviews the available stratigraphic evidence from the Himalayan region, and concludes that only in the western Zanskar-Hazara region is the age well constrained as starting in the Late Ypresian (˜ < 52 Ma). To the east only in the Malla Johar region of the Tethyan Himalayas have potentially syn-collisional sediments been recognized south of the Indus Yarlung Zangbo suture. However, here the correlation of the upper part of the Sangchamalla Flysch is contentious, with correlations ranging from Late Cretaceous to Middle Eocene (Lutetian). In the most eastern sections of Tertiary rocks thus far recognized within the Tethyan Himalayas north and east of Everest (Mount Qomolangma) normal, shallow shelf-type carbonates extend into the Lutetian, without evidence of a change in sedimentation to the top of the section, so the start of collision must be still younger. Along-strike of the Indus Yarlung Zangbo suture thick submarine delta-fan complexes derived from erosion of the Himalayan-Tibet system provide independent estimates that agree with a diachronous collision initiating in the late Ypresian in the west and progressing into and perhaps through the Lutetian in the east. The stratigraphic and magmatic history along the north side of the suture are compatible with such a diachronous history. This diachroneity has important implications for estimates of the accommodation of strain within this orogenic system.

  2. The Age of Initiation of Drug Use and Sexual Behavior May Influence Subsequent HIV Risk Behavior: A Systematic Review

    2013-01-01

    Researchers examining injection drug users (IDUs) in drug treatment have been trying for decades to determine the optimal way to intervene to prevent the transmission and spread of human immunodeficiency virus (HIV) in this population. Although efficacious HIV risk reduction interventions are widely available, questions remain about what specific factors are most related to HIV risk behavior and defined as unprotected sexual activity and/or high risk drug use. This review involved an evaluation of the research literature in order to better understand the association between drug use and sexual behavior debut on HIV risk behavior. Findings suggest that drug use debut and sexual behavior debut may be related to subsequent HIV risk behavior. Evidence to date implies that intervening at an earlier age to assist youth to avoid or delay these high risk behaviors may be an additional means of reducing subsequent HIV risk. PMID:24381791

    2016-01-01

    The present review has mainly focused on the specific parameters including aging (aging days, temperature, relative humidity, and air flow), eating quality (flavor, tenderness and juiciness), microbiological quality and economic (shrinkage, retail yields and cost) involved beef dry aging process. Dry aging is the process where beef carcasses or primal cuts are hanged and aged for 28 to 55 d under controlling environment conditions in a refrigerated room with 0° to 4 °C and with relative humidity of 75 to 80 %. However there are various opinions on dry aging procedures and purveyors of such products are passionate about their programs. Recently, there has been an increased interest in dry aging process by a wider array of purveyors and retailers in the many countries. Dry aging process is very costly because of high aging shrinkage (6 to15 %), trims loss (3 to 24 %), risk of contamination and the requirement of highest grades meat with. The packaging in highly moisture-permeable bag may positively impact on safety, quality and shelf stability of dry aged beef. The key effect of dry aging is the concentration of the flavor that can only be described as "dry-aged beef". But the contribution of flavor compounds of proteolysis and lipolysis to the cooked dry aged beef flavor is not fully known. Also there are limited scientific studies of aging parameters on the quality and palatability of dry aged beef. PMID:27200180

    Psychological resilience is comprised of an adaptive functioning standard before the current and accumulated risks of life. Furthermore, it has a comprehensive range of psychological resources which are essential to overcome adversities, such as personal competences, self-beliefs and interpersonal control which interact with the social networks support. The objectives are to show the concepts of psychological resilience in elderly, relative to dominant theoretical models and the main data about psychological resilience in aging, found in an international and Brazilian review from 2007 to 2013. The descriptors "resilience, psychological resilience and aging", "resiliência e envelhecimento, velhice e velho", were used in PubMed, PsychInfo, SciELO and Pepsic databases. Fifty three international and eleven national articles were selected. The international articles were classified in four categories: psychological and social coping resources, emotional regulation before stressing experiences, successful resilience and aging and correlates, and resilience measures. The Brazilian articles were grouped in three: psychological and social resources, resilience in carers and theory review. Articles on psychological resources and on emotional regulation prevailed as key factors associated with psychological resilience in aging. PMID:26017950

This initial effort focused on a pristine sample, and a replicate sample irradiated in air at a dose of 25MR. Thermal degradation was investigated by performing Thermogravimetric Analysis (TGA), and radiation-induced degradation was investigated using Differential Scanning Calorimetry (DSC), X-ray Diffraction (XRD), Solid Phase MicroExtraction--Gas Chromatography/Mass Spectrometry (SPME-GC/MS), as well as various Nuclear Magnetic Resonance (NMR) techniques including: {sup 13}C, {sup 13}C {sup 1}H cross polarization (CP), and {sup 1}H magic angle spinning (MAS) NMR.

  6. Review Of Internet Health Information Quality Initiatives

    PubMed Central

    Dzenowagis, Joan

    2001-01-01

    Background The massive growth of health information on the Internet; the global nature of the Internet; the seismic shift taking place in the relationships of various actors in this arena, and the absence of real protection from harm for citizens who use the Internet for health purposes are seen to be real problems. One response to many of these problems has been the burgeoning output of codes of conduct by numerous organizations trying to address quality of health information. Objectives Review the major self-regulatory initiatives in the English-speaking world to develop quality and ethical standards for health information on the Internet. Compare and analyze the approaches taken by the different initiatives. Clarify the issues around the development and enforcement of standards. Methods Quality initiatives selected meet one or more of the following criteria: Self-regulatory. A reasonable constituency. Diversity (eg, of philosophy, approach and process)-to achieve balance and wide representation, and to illustrate and compare different approaches. Historic value. A wider reach than a national audience, except when its reach is a significant sector of the Internet health information industry. The initiatives were compared in 3 ways: (1) Analysis and comparison of: key concepts, mechanism, or approach. Analysis of: the obligations that a provider has to meet to comply with the given initiative, the intended beneficiaries of that initiative, and the burdens imposed on different actors. These burdens are described in terms of their effect on the long-term sustainability and maintenance of the initiative by its developers. Analysis of the enforcement mechanisms. (2) Analysis and comparison by type of sponsoring organization, the reach of the initiative, and the sources of funding of the initiative or the sponsoring organization. (3) How the various initiatives fall under 1 of 3 key mechanisms and comparison of the advantages and disadvantages of these key mechanisms

  7. CASL Validation Data: An Initial Review

    The study aims to establish a comprehensive view of “data” needed for supporting implementation of the Consortium of Advanced Simulation of LWRs (CASL). Insights from this review (and its continual refinement), together with other elements developed in CASL, should provide the foundation for developing the CASL Validation Data Plan (VDP). VDP is instrumental to the development and assessment of CASL simulation tools as predictive capability. Most importantly, to be useful for CASL, the VDP must be devised (and agreed upon by all participating stakeholders) with appropriate account for nature of nuclear engineering applications, the availability, types and quality of CASL-related data, and novelty of CASL goals and its approach to the selected challenge problems. The initial review (summarized on the January 2011 report version) discusses a broad range of methodological issues in data review and Validation Data Plan. Such a top-down emphasis in data review is both needed to see a big picture on CASL data and appropriate when the actual data are not available for detailed scrutiny. As the data become available later in 2011, a revision of data review (and regular update) should be performed. It is expected that the basic framework for review laid out in this report will help streamline the CASL data review in a way that most pertinent to CASL VDP.

  8. Invited review: aging and human temperature regulation.

    PubMed

    Kenney, W Larry; Munce, Thayne A

    2003-12-01

    This mini-review focuses on the effects of aging on human temperature regulation. Although comprehensive reviews have been published on this topic (Kenney WL. Exercise and Sport Sciences Reviews, Baltimore: Williams & Wilkins, 1997, p. 41-76; Pandolf KB. Exp Aging Res 17: 189-204, 1991; Van Someren EJ, Raymann RJ, Scherder EJ, Daanen HA, and Swaab DF. Ageing Res Rev 1: 721-778, 2002; and Young AJ. Exp Aging Res 17: 205-213, 1991), this mini-review concisely summarizes the present state of knowledge about human temperature regulation and aging in thermoneutral conditions, as well as during hypo- and hyperthermic challenges. First, we discuss age-related effects on baseline body core temperature and phasing rhythms of the circadian temperature cycle. We then examine the altered physiological responses to cold stress that result from aging, including attenuated peripheral vasoconstriction and reduced cold-induced metabolic heat production. Finally, we present the age-related changes in sweating and cardiovascular function associated with heat stress. Although epidemiological evidence of increased mortality among older adults from hypo- and hyperthermia exists, this outcome does not reflect an inability to thermoregulate with advanced age. In fact, studies that have attempted to separate the effects of chronological age from concurrent factors, such as fitness level, body composition, and the effects of chronic disease, have shown that thermal tolerance appears to be minimally compromised by age.

    Va'Vra, J.

    1986-02-01

    This paper makes an overview of the wire chamber aging problems as a function of various chamber design parameters. It emphasizes the chemistry point of view and many examples are drawn from the plasma chemistry field as a guidance for a possible effort in the wire chamber field. The paper emphasizes the necessity of variable tuning, the importance of purity of the wire chamber environment, as well as it provides a practical list of presently known recommendations. In addition, several models of the wire chamber aging are qualitatively discussed. The paper is based on a summary talk given at the Wire Chamber Aging Workshop held at LBL, Berkeley on January 16-17, 1986. Presented also at Wire Chamber Conference, Vienna, February 25-28, 1986. 74 refs., 18 figs., 11 tabs.

    2000-01-01

    Preventive nutrition in the elderly is reviewed also from points of view of the concepts of prevention, nutrition and old age, respectively. The demographic, medical, psychosocial and other differences between individuals of the same age but belonging to different birth cohorts are emphasized, as well as the need for a multifactorial preventive approach. The interaction between dietary aspects and physical activity is discussed, and it is also pointed out that risk indicators and risk factors may be different in old age compared to middle life. Finally, public health aspects and "hospital malnutrition" are dealt with in this review. PMID:10842424

  17. Initial aging phenomena in copper-chromium alloys

    NASA Technical Reports Server (NTRS)

    Suzuki, H.; Motohiro, K.

    1985-01-01

    The effects of quenching and aging temperatures on the initial aging curves of Cu-Cr alloy were examined mainly by means of electrical resistivity measurements. Three Cu-Cr alloy specimens having 0.24, 0.74, and 1.0% Cr were solution-treated at 950-1050 C, quenched into ice-water, and subsequently aged at 300-500 C. The results were as follows: (1) At the very early stage of aging (within about 30 sec), an abrupt decrease of resistivity with lowering aging tempratures. (T sub A) and rising solution temperatures (T sub S) was observed at (T sub A) up to about 400 C. In contrast, a transient increase of resistivity with rising T sub A and lowering T sub S was observed at T sub A from about 450 to 500 C. These phenomena seem to be caused by a rapid formation of solute clusters and the reversion of clusters formed during quenching, which are enhanced by quenched-in vacancies, respectively. (2) The amount of precipitation increased at the latter stage of aging with rising T sub S and T sub A as generally expected, where T sub S was not so high as to form secondary defects. (3) As a result, the initial aging phenomena in Cr-Cr alloy were revealed to be complicated against expectations. This was considered to be due to the migration energy of vacancies so larger in Cu-base.

  7. The immune system and aging: a review.

    PubMed

    Castelo-Branco, Camil; Soveral, Iris

    2014-01-01

    Abstract The concept of immunosenescence reflects age-related changes in immune responses, both cellular and serological, affecting the process of generating specific responses to foreign and self-antigens. The decline of the immune system with age is reflected in the increased susceptibility to infectious diseases, poorer response to vaccination, increased prevalence of cancer, autoimmune and other chronic diseases. Both innate and adaptive immune responses are affected by the aging process; however, the adaptive response seems to be more affected by the age-related changes in the immune system. Additionally, aged individuals tend to present a chronic low-grade inflammatory state that has been implicated in the pathogenesis of many age-related diseases (atherosclerosis, Alzheimer's disease, osteoporosis and diabetes). However, some individuals arrive to advanced ages without any major health problems, referred to as healthy aging. The immune system dysfunction seems to be somehow mitigated in this population, probably due to genetic and environmental factors yet to be described. In this review, an attempt is made to summarize the current knowledge on how the immune system is affected by the aging process. PMID:24219599

    2014-01-01

    In this article, we examine the existing sociocultural research and theory concerned with the aging body. In particular, we review the body image and embodiment literatures and discuss what is known about how older adults perceive and experience their aging bodies. We analyse how body image is shaped by age, culture, ethnicity, gender, health status, sexual preference, and social class. Additionally, we critically elucidate the embodiment literature as it pertains to illness experiences, sexuality, the everyday management of the aging body, appearance work, and embodied identity. By outlining the key findings, theoretical debates, and substantive discrepancies within the body image and embodiment research and theory, we identify gaps in the literature and forecast future, much-needed avenues of investigation.

Although research on aging families has advanced theory and applied innovative statistical techniques, the literature has fallen short in fully representing diverse populations and in applying the broadest set of methodological tools available. We discuss these and other frontier areas of scholarship in light of the aging of baby boomers and their families. PMID:22930600

    A cross-sectional survey on tobacco use in the city of Alexandria, Egypt, used an interview questionnaire based on World Health Organization guidelines. The study in 2000 included 2120 participants aged 15 to 86 years. More than a quarter (27.2%) were current smokers (25.5% daily smokers and 1.7% occasional smokers) and 3.5% were ex-smokers. Current smokers spent 23.1% of their family income on tobacco. The prevalence of current smoking was significantly higher among men (48.5%) than women (1.5%) and the mean age of initiation of smoking was lower among men (18.1 years) than women (22.6 years). The high prevalence of tobacco use among men is of concern, so too is the likelihood that tobacco use will increase among women. Further research is needed into factors that prevent people from starting smoking and assist them stopping smoking. PMID:15603046

    The accumulation of senescent stromal cells in aging tissue changes the local microenvironment from normal to a state similar to chronic inflammation. This inflammatory microenvironment can stimulate the proliferation of epithelial cells containing DNA mutations which can ultimately lead to cancer. Using geriatric skin as a model, we demonstrated that senescent fibroblasts also alter how epithelial keratinocytes respond to genotoxic stress, due to the silencing of IGF-1 expression in geriatric fibroblasts. These data indicate that in addition to promoting epithelial tumor growth, senescent fibroblasts also can promote carcinogenic initiation. We hypothesized that commonly used therapeutic stromal wounding therapies can reduce the percentage of senescent fibroblasts and consequently prevent the formation of keratinocytes proliferating with DNA mutations following acute genotoxic (UVB) stress. Sun-protected skin on the lower back of geriatric human volunteers was wounded by dermabrasion and the skin was allowed to heal for three months. In geriatric skin, we found that dermabrasion wounding decreases the proportion of senescent fibroblasts found in geriatric dermis, increases the expression of IGF-1, and restores the appropriate UVB response to epidermal keratinocytes in geriatric skin. Therefore, dermal rejuvenation therapies may play a significant role in preventing the initiation of skin cancer in geriatric patients. PMID:21515933

    Purpose To examine the relationship between country-level age norms for sexual initiation timing and early sexual initiation (ESI) among adolescent boys and girls. Methods Nationally-representative data from 17 countries that participated in the 2006/07 European Social Survey (ESS-3, n=33,092) and the 2005/06 Health Behaviour in School-Aged Children Study (HBSC, n=27,702) were analyzed. Age norms were measured as the average country-level response to an item asking the age at which ESS respondents believed someone is too young to have sexual intercourse. HBSC respondents (aged 14-16) self-reported age at sexual initiation which we defined as early (<15 years) or not (≥15 years or no initiation). Control variables included age, family affluence, perceived socioeconomic status, family living arrangement, substance use, school attachment, and country-level legal age of consent. Multivariable three-level logistic models with random intercepts were run separately by sex. Results In multivariable analyses, higher overall age norms were associated with reduced likelihood of ESI among girls (AOR 0.60, 95% CI 0.45-0.79); associations with ESI were stronger for parent cohort (ages 31-65) norms (AOR 0.37, 95% CI 0.23-0.58) than for peer cohort (ages 15-20) norms (AOR 0.60, 95% CI 0.49-0.74). For boys, overall norms were also significantly negatively associated with ESI (AOR 0.68, 95% CI 0.46-0.99), as were parent cohort norms (AOR 0.66, 95% CI 0.45-0.96). Peer cohort norms were not significantly related to boys’ ESI. Conclusion Macro-level cultural norms may impact adolescents’ sexual initiation timing. Research exploring the sexual health outcomes of early initiators in countries with contrasting age norms is warranted. PMID:24508092

  15. Age at Time of Initial Sexual Intercourse and Health of Adolescent Girls.

    PubMed

    Lara, Lúcia A S; Abdo, Carmita H N

    2016-10-01

    Adolescence is characterized by marked changes in the body, psychology, and sexual behavior due to increasing production of hormones. In this review we aimed to assess the effect of age at the time of first sexual intercourse (sexarche) on the health of adolescent girls, and identify factors that might protect against early initiation of sexual relations in girls. The PubMed, Lilacs, and Google Scholar databases were searched for clinical trials, comparative studies, case-control studies, cross-sectional studies, cohort studies, multicenter studies, observational studies, meta-analyses, and systematic reviews published up to December 2014 on this theme. The search terms were: "sexual debut," "coitarche," "sexarche," and "young people," "adolescent," "unplanned pregnancy," "adolescent contraception," and "STDs." Data were extracted from 28 studies and 41 references were used to introduce the theme and to support the discussion. Sexarche has been occurring in increasingly younger girls. A young age at sexarche can lead to subsequent risky sexual behavior. Girls who have sexarche when they are 14 years old or younger are less likely to use contraception on this occasion, take more time before they start using contraception in subsequent sexual relations, are more likely to have several sex partners, have a higher risk for depression, have lower self-esteem and more episodes of repentance, and have a higher risk for a sexually transmitted disease and cervical cancer. Girls with low educational, socioeconomic, and cultural status, little parental monitoring, parental separation, and absence of religiosity tend to experience sexarche at a younger age. Adolescent girls who postpone sexarche until they are 16 years old are physically and psychologically healthier than those who have sexarche at a younger age. This suggests that providing adolescent girls with appropriate education about sexual relations might reduce the negative effect of sexual relations at a young age

  18. Humor and aging - a mini-review.

    PubMed

    Greengross, Gil

    2013-01-01

    Humor is one of the most important human activities, one that is enjoyed daily by people in every culture and at every age. However, very little is known about how aging affects humor experiences. Research suggests that elderly people enjoy humor more than younger people, but they have increasing difficulties in understanding jokes. Several cognitive mechanisms that may help explain this trend are discussed. Also, the amount of laughter exhibited by the elderly is smaller compared to young adults. In addition, the older population seems not to enjoy aggressive types of humor as much as the younger ones, and the elderly are especially sensitive to jokes referring to old age. Because most studies are cross-sectional, we cannot ignore possible cohort effects that might influence age differences in humor production and humor appreciation. Several future directions are mentioned with the hope for further research on the subject to follow. PMID:23689078

    Decreased olfactory function is very common in the older population, being present in >50% of individuals aged between 65 and 80 years and in 62-80% of those >80 years of age. Smell dysfunction significantly influences physical well-being, quality of life, nutritional status as well as everyday safety and is associated with increased mortality. Multiple factors contribute to age-related olfactory sensory loss, including nasal engorgement, cumulative damage of the olfactory epithelium from environmental insults, a reduction in mucosal metabolizing enzymes, sensory loss of receptor cells to odorants, and changes in neurotransmitter and neuromodulator systems. In addition, structural and functional abnormalities of the olfactory epithelium, olfactory bulb, central olfactory cortex, and basic olfactory circuitry, which are related to the neuronal expression of aberrant proteins in these areas, may result in olfactory sensory impairment in aging and neurodegenerative diseases. Impaired odour identification is associated with a decrease in cognitive abilities and memory decline. A reduction in the sense of smell is considered to potentially represent an early and important warning of neurodegenerative disorders, particularly of Parkinson's disease and Alzheimer's disease, and, in mild cognitive impairment, olfactory impairment may herald progression to dementia. Further investigations of the potential role of olfactory dysfunction in the early diagnosis and treatment of neurodegenerative diseases are warranted. PMID:25968962

    The oxidative evolution (“aging”) of organic species in the atmosphere is thought to have a major influence on the composition and properties of organic particulate matter, but remains poorly understood, particularly for the most oxidized fraction of the aerosol. Here we measure the kinetics and products of the heterogeneous oxidation of highly oxidized organic aerosol, with an aim of better constraining such atmospheric aging processes. Submicron particles composed of model oxidized organics—1,2,3,4-butanetetracarboxylic acid (C{sub 8}H{sub 10}O{sub 8}), citric acid (C{sub 6}H{sub 8}O{sub 7}), tartaric acid (C{sub 4}H{sub 6}O{sub 6}), and Suwannee River fulvic acid—were oxidized by gas-phase OH in a flow reactor, and the masses and elemental composition of the particles were monitored as a function of OH exposure. In contrast to our previous studies of less-oxidized model systems (squalane, erythritol, and levoglucosan), particle mass did not decrease significantly with heterogeneous oxidation. Carbon content of the aerosol always decreased somewhat, but this mass loss was approximately balanced by an increase in oxygen content. The estimated reactive uptake coefficients of the reactions range from 0.37 to 0.51 and indicate that such transformations occur at rates corresponding to 1-2 weeks in the atmosphere, suggesting their importance in the atmospheric lifecycle of organic particulate matter.

    2015-01-01

    Introduction Earlier initiation of cannabis use is associated with poorer neuropsychological functioning across several domains. Given well-documented sex differences in neuromaturation during adolescence, initiation of cannabis use during this time may affect neuropsychological functioning differently for males and females. Method In the current study, we examined sex differences in the relationship between age of initiated cannabis use and neuropsychological performance after controlling for amount of lifetime cannabis use in 44 male and 25 female young adult cannabis users. Results We found that an earlier age of initiated use was related to poorer episodic memory, especially immediate recall, in females, but not in males. On the other hand, we found that, surprisingly, an earlier age of initiated use was associated with better decision-making overall. However, exploratory analyses found sex-specific factors associated with decision-making and age of initiated use, specifically that ADHD symptoms in females may drive the relationship between an earlier age of initiated use and better decision-making. Further, an earlier age of initiated use was associated with less education, a lower IQ, and fewer years of mother’s education for females, but more lifetime cannabis use for males. Conclusions Taken together, our findings suggest there are sex-differences in the associations between age of initiated cannabis use and neuropsychological functioning. The current study provides preliminary evidence that males and females may have different neuropsychological vulnerabilities that place them at risk for initiating cannabis use and continued cannabis use, highlighting the importance of examining the impact of cannabis on neuropsychological functioning separately for males and females.

  9. Review: Axon pathology in age-related neurodegenerative disorders.

    PubMed

    Adalbert, R; Coleman, M P

    2013-02-01

    'Dying back' axon degeneration is a prominent feature of many age-related neurodegenerative disorders and is widespread in normal ageing. Although the mechanisms of disease- and age-related losses may differ, both contribute to symptoms. Here, we review recent advances in understanding axon pathology in age-related neurodegenerative disorders such as Alzheimer's disease, Parkinson's disease, amyotrophic lateral sclerosis and glaucoma. In particular, we highlight the importance of axonal transport, autophagy, traumatic brain injury and mitochondrial quality control. We then place these disease mechanisms in the context of changes to axons and dendrites that occur during normal ageing. We discuss what makes ageing such an important risk factor for many neurodegenerative disorders and conclude that the processes of normal ageing and disease combine at the molecular, cellular or systems levels in a range of disorders to produce symptoms. Pathology identical to disease also occurs at the cellular level in most elderly individuals. Thus, normal ageing and age-related disease are inextricably linked and the term 'healthy ageing' downplays the important contributions of cellular pathology. For a full understanding of normal ageing or age-related disease we must study both processes. PMID:23046254

    The purpose of this document is to provide readers with a resource of different ongoing standardization efforts within the ‘omics’ (genomic, proteomics, metabolomics) and related communities, with particular focus on toxicological and environmental applications. The review includes initiatives within the research community as well as in the regulatory arena. It addresses data management issues (format and reporting structures for the exchange of information) and database interoperability, highlighting key objectives, target audience and participants. A considerable amount of work still needs to be done and, ideally, collaboration should be optimized and duplication and incompatibility should be avoided where possible. The consequence of failing to deliver data standards is an escalation in the burden and cost of data management tasks. PMID:18629184

    Background. Pelvic exenteration and multivisceral resection in colorectal have been described as a curative and palliative intervention. Urinary tract reconstruction in a pelvic exenteration is achieved in most cases with an ileal conduit of Bricker, although different urinary reservoirs have been described. Methods. A retrospective and observational study of six patients who underwent a pelvic exenteration and urinary tract reconstruction with a double barreled wet colostomy (DBWC) was done, describing the preoperative diagnosis, the indication for the pelvic exenteration, the complications associated with the procedure, and the followup in a period of 5 years. A literature review of the case series reported of the technique was performed. Results. Six patients had a urinary tract reconstruction with the DBWC technique, 5 male patients and one female patient. Age range was from 20 to 77 years, with a medium age 53.6 years. The most frequent complication presented was a pelvic abscess in 3 patients (42.85%); all complications could be resolved with a conservative treatment. Conclusion. In the group of our patients with pelvic exenteration and urinary tract reconstruction with a DBWC, it is a safe procedure and well tolerated by the patients, and most of the complications can be resolved with conservative treatment.

  9. The effects of calorie restriction on aging: a brief review.

    PubMed

    Al-Regaiey, K A

    2016-06-01

    Calorie restriction (CR) without malnutrition slows aging and increase average and maximal lifespan in model organisms and rodents. In human and non-human primates, CR has beneficial effects on human longevity and reduces the incidence of age-related diseases such as obesity, diabetes mellitus hypertension, cardiovascular disease and cancer. CR exerts its anti-aging effects through different mechanisms including small noncoding RNA molecules (sncRNAs), the composition of diet and IGF-1 signaling. The aim of this review was to discuss recent developments to understand the consequences and mechanisms of CR on longevity. PMID:27338076

    Maternal age at first childbirth has increased in most developed countries in the past 20 years. The purpose of this study is to investigate effects of maternal age at delivery and parity on successful initiation of exclusive breastfeeding (EBF). This retrospective study investigated 1193 singleton dyads with vaginal-delivered at 37-42 gestational weeks during January and December in 2011 at one large "Baby-Friendly" certified hospital in Japan. A multivariate logistic regression model was used to evaluate individual and combined effects of maternal age and parity on successful initiation of EBF after adjusted for pre-pregnancy body mass index, gestational weight gain, pregnancy complications, mothers' underlying illness, smoking and alcohol drinking habits, gestational week at delivery, child's sex and nurturing support from grandparents. Success rates of EBF at one month after child delivery was 69.4% in primiparous aged ≥ 35 (group A: n = 284), 73.5% in multiparous aged ≥ 35 (group B: n = 268), 74.3% in primiparous aged < 35 (group C: n = 432), and 82.3% in multiparous aged < 35 (group D: n = 209). Older maternal age and primiparous became independently associated with EBF initiation. The combined effect for successful initiation of EBF was the lowest in group A referent to group D both at discharge and at one month (odds ratio (OR) 5.9, 95% confidence interval (CI): 3.0-11.9, and OR 2.2, 95% CI: 1.4-3.4, respectively). Primiparous mothers in late child-bearing aged 35 years or older are at the greatest risk of EBF initiation. PMID:26844198

    Objectives. We examined the relation between childhood sexual abuse and injection drug use initiation among young adult injection drug users. Methods. We used mixed effect linear models to compare age at first injection among 2143 young injection drug users by first sexual abuse age categories. Results. The participants were predominantly male (63.3%) and White (52.8%). Mean age and age at first injection were 23.7 and 19.6 years, respectively; 307 participants (14.3%) reported childhood sexual abuse. After adjustment for gender, race/ethnicity, noninjection drug use before first injection drug use, and recruitment site, childhood sexual abuse was independently associated with younger age at first injection. Conclusions. Childhood sexual abuse was associated with earlier initiation of injection drug use. These data emphasize the need to integrate substance abuse prevention with postvictimization services for children and adolescents. PMID:15798133

    As called for in the March 24, 2010, Memorandum of Understanding (MOU) for Hydropower, the U.S. Department of Energy (DOE), the U.S. Department of the Interior (DOI), the U.S. Army Corps of Engineers (USACE), environmental stakeholders, and the hydropower industry are collaborating to identify opportunities to simultaneously increase electricity generation and improve environmental services in river basins of the United States. New analytical tools provide an improved ability to understand, model, and visualize environmental and hydropower systems. Efficiencies and opportunities that might not be apparent in site-by-site analyses can be revealed through assessments at the river-basin scale. Information from basin-scale assessments could lead to better coordination of existing hydropower projects, or to inform siting decisions (e.g., balancing the removal of some dams with the construction of others), in order to meet renewable energy production and environmental goals. Basin-scale opportunity assessments would inform energy and environmental planning and address the cumulative effects of hydropower development and operations on river basin environmental quality in a way that quantifies energy-environment tradeoffs. Opportunity assessments would create information products, develop scenarios, and identify specific actions that agencies, developers, and stakeholders can take to locate new sustainable hydropower projects, increase the efficiency and environmental performance of existing projects, and restore and protect environmental quality in our nation's river basins. Government agencies and non-governmental organizations (NGO) have done significant work to understand and assess opportunities for both hydropower and environmental protection at the basin scale. Some initiatives have been successful, others less so, and there is a need to better understand the legacy of work on which this current project can build. This background literature review is intended to

    There is evidence that telomere length (TL), telomerase activity (TA), and age are related to the replicative potential of human nucleus pulposus chondrocytes (NPCs). However, it has not yet been established if any of these factors can serve as predictors of the replicative potential of NPCs. To establish predictors of the replicative potential of NPCs, we evaluated potential relationships between replicative capacity of NPCs, initial TL (telomere length at the first passage), initial TA (telomerase activity at the first passage), and age. Nucleus pulposus specimens were obtained from 14 patients of various ages undergoing discectomy. NPCs were serially cultivated until the end of their replicative lifespans. Relationships among cumulative population doubling level (PDL), initial TL, initial TA, and age were analyzed. Initial TA was negatively correlated with age (r = -0.674, P = 0.008). However, no correlation between initial TL and age was observed. Cumulative PDL was also negatively correlated with age (r = -0.585, P = 0.028). Although the cumulative PDL appeared to increase with initial TL or initial TA, this trend was not statistically significant. In conclusion, age is the sole predictor of the replicative potential of human NPCs, and replicative potential decreases with age. Initial TL and initial TA are not predictors of replicative potential, and can serve only as reference values. PMID:26633809

    Background It is generally accepted that smoking starts in adolescence and earlier initiation is associated with more negative health outcomes. Some research suggests that women initiate smoking at later ages and have more negative health outcomes than men. The purpose of this study was to examine gender differences in age of initiation and its association with health. Methods The sample included men (n=8,506) and women (n=8,479) with a history of smoking from the 2001-2002 National Epidemiological Survey of Alcohol Related Conditions. Logistic regression was used to examine gender differences in the effect of late smoking initiation on physical and mental health status after adjusting for covariates. Results At mostly all ages after 16, women exceeded men in rates of smoking initiation (59.8% vs. 50.3%, p<.001). Among late initiators (≥16), women were more likely than men to have hypertension (OR:1.24,CI:1.09-1.41), heart disease (OR:1.20,CI:1.00-1.45), major depressive disorder (OR:2.54,CI:2.22-2.92) and generalized anxiety disorder (OR:2.34,CI:1.84-2.99). Among early initiators (<16), women were more likely than men to have major depressive disorder (OR:2.42,CI:2.11-2.77) and generalized anxiety disorder (OR:2.01,CI:1.59-2.54) but there were no gender differences in the likelihood of having hypertension (OR:1.04,CI:0.89-1.22) and heart disease (OR:1.11,CI:0.90-1.36). Conclusions In late adolescence and adulthood, women exceed men in smoking initiation. Late initiation was associated with more significant physical health risks for women than men. Our findings raise questions about generally accepted notions on the age at which smoking initiation occurs and its association with health.

    Objective To examine the trend of provider-verified HPV vaccine initiation (≥1 dose) and completion (≥3 doses) among adolescent girls at the Advisory Committee on Immunization Practices (ACIP) recommended age (11-12 years). Methods We analyzed National Immunization Survey of Teens 2008-2012 data and examined the trend of provider-verified HPV vaccine initiation and completion among <13 year old girls. Results Data on age at HPV vaccine initiation and completion were available for 24,466 and 15,972 girls, respectively. The weighted proportion of girls who initiated the vaccine at <13 years of age was 14.1%, 24.1%, 35.9%, 47.7% and 55.9% in 2008, 2009, 2010, 2011 and 2012, respectively (p for trend <.001). The similar trend was also observed for mean age at HPV vaccine initiation and completion (p <.001). Conclusions Additional efforts are needed to increase HPV vaccine uptake among adolescent girls as only half of them receive this vaccine at ACIP recommended age. PMID:25529289

  17. NSF Geosciences Initiatives and Plans Reviewed at Advisory Committee Meeting

    2010-10-01

    In its semiannual meeting on 6-7 October, the U.S. National Science Foundation's (NSF) Advisory Committee for Geosciences (GEO) reviewed GEO initiatives, programs, and plans, including the GEO directorate's fast and significant response to support research related to various aspects of the Deepwater Horizon oil spill in the Gulf of Mexico through Rapid Response Research (RAPID) awards and other measures. An undercurrent during the meeting was concern about workload stress among GEO staff. Assistant director of geosciences Tim Killeen noted that the proposed budget for fiscal year (FY) 2011, which began on 1 October, would increase directorate funding 7.4% over FY 2010, if the budget is approved by Congress. A continuing resolution in Congress maintains FY 2010 funding levels until at least 3 December. Killeen said NSF's budget request for FY 2012 has been submitted to the White House Office of Management and Budget, adding that although he cannot discuss details of that budget yet, GEO Vision, a long­range strategy document for the directorate released in October 2009, “is reflected in our thinking going forward.”

    BACKGROUND: Quantifying pediatric immunologic recovery by highly active antiretroviral therapy (HAART) initiation at different CD4 percentage (CD4%) and age thresholds may inform decisions about timing of treatment initiation. METHODS: HIV-1-infected, HAART-naive children in Europe and the Americas were followed from 2002 through 2009 in PENPACT-1. Data from 162 vertically infected children, with at least World Health Organization “mild” immunosuppression and CD4% <10th percentile, were analyzed for improvement to a normal CD4% (≥10th percentile) within 4 years after HAART initiation. Data from 209 vertically infected children, regardless of immune status, were analyzed for CD4% outcomes at 4 years and viral failure within 4 years. RESULTS: Seventy-two percent of baseline immunosuppressed children recovered to normal within 4 years. Compared with “severe” immunosuppression, more children with “mild” immunosuppression (difference 36%, 95% confidence interval [CI]: 22% to 49%) or “advanced” immunosuppression (difference 20.8%, 95% CI: 5.8% to 35.9%) recovered a normal CD4%. For each 5-year increase in baseline age, the proportion of children achieving a normal CD4% declined by 19% (95% CI: 11% to 27%). Combining baseline CD4% and age effects resulted in >90% recovery when initiating HAART with “mild” immunosuppression at any age or “advanced” immunosuppression at age <3 years. Baseline CD4% effects became greater with increasing age (P = .02). At 4 years, most immunologic benefits were still significant but diminished. Viral failure was highest in infancy (56%) and adolescence (63%). CONCLUSIONS: Initiating HAART at higher CD4% and younger ages maximizes potential for immunologic recovery. Guidelines should weigh immunologic benefits against long-term risks. PMID:25266426

  8. Neuroimaging of Mobility in Aging: A Targeted Review

    PubMed Central

    Epstein, Noah; Mahoney, Jeannette R.; Izzetoglu, Meltem; Blumen, Helena M.

    2014-01-01

    Background. The relationship between mobility and cognition in aging is well established, but the relationship between mobility and the structure and function of the aging brain is relatively unknown. This, in part, is attributed to the technological limitations of most neuroimaging procedures, which require the individual to be immobile or in a supine position. Herein, we provide a targeted review of neuroimaging studies of mobility in aging to promote (i) a better understanding of this relationship, (ii) future research in this area, and (iii) development of applications for improving mobility. Methods. A systematic search of peer-reviewed studies was performed using PubMed. Search terms included (i) aging, older adults, or elderly; (ii) gait, walking, balance, or mobility; and (iii) magnetic resonance imaging, voxel-based morphometry, fluid-attenuated inversion recovery, diffusion tensor imaging, positron emission tomography, functional magnetic resonance imaging, electroencephalography, event-related potential, and functional near-infrared spectroscopy. Results. Poor mobility outcomes were reliably associated with reduced gray and white matter volume. Fewer studies examined the relationship between changes in task-related brain activation and mobility performance. Extant findings, however, showed that activation patterns in the cerebellum, basal ganglia, parietal and frontal cortices were related to mobility. Increased involvement of the prefrontal cortex was evident in both imagined walking conditions and conditions where the cognitive demands of locomotion were increased. Conclusions. Cortical control of gait in aging is bilateral, widespread, and dependent on the integrity of both gray and white matter. PMID:24739495

  9. The social ecology of adolescent-initiated parent abuse: a review of the literature.

    2012-06-01

    This article provides an ecological framework for understanding adolescent-initiated parent abuse. We review research on adolescent-initiated parent abuse, identifying sociodemographic characteristics of perpetrators and victims (e.g., gender, age, race/ethnicity, and socioeconomic status [SES]). Bronfenbrenner's [1] ecological systems theory is applied, which examines the risk and protective factors for adolescent-initiated parent abuse within micro- (maltreatment, domestic violence, parenting behavior and disciplinary strategies), meso- (peer influence), exo- (media influence), macro- (gender role socialization), and chronosystem (change in family structure) levels. Findings from our review suggest that older and White children are significantly more likely to abuse their parents. Females are selective in the target of their aggression, while males target family members in general. Mothers are significantly more likely to be abused than fathers. However, researchers also report variations in the association between SES and parent abuse. Domestic violence and child maltreatment are risk factors, while findings on parenting behavior and disciplinary strategies are mixed. Peer influence, exposure to media violence, gender role socialization, and change in family structure can potentially increase the risk of parent abuse. Practice and research implications are also discussed. An ecological systems framework allows for an examination of how various contexts interact and influence parent abuse behavior, and can provide needed directions for further research. PMID:22160270

  10. Pharmacotherapy in the ageing patient: The impact of age per se (A review).

    Singh, Shamsher; Bajorek, Beata

    2015-11-01

    A literature search was carried out to review the influence of 'ageing' on pharmacotherapeutic decision-making, specifically how 'age' is defined and considered in the utilisation of medication. Embase, Medline, International Pharmaceutical Abstracts, and Google scholar were canvassed in a three-tiered search according to pre-established inclusion criteria. In tier 1, a total of 22 studies were identified highlighting the underutilisation of medication in elderly patients, with a particular focus on warfarin. Four studies highlighted an age-bias in medication-prescribing for elderly patients, specifically in relation to medicines for rheumatoid arthritis, angina, and hypertension. Tier 2 identified diverse definitions for 'elderly', including biological age, chronological age, physiological age, as well as various descriptions of 'elderly' in clinical trials and guidelines. Finally, medication optimisation tools were identified through the third tier, emphasising the use of chronological age to describe the 'elderly'. Old age influences pharmacotherapeutic decision-making at various levels, however, what complicates the situation is the absence of a comprehensive definition of 'elderly'. Clinical recommendations need to be based more on objective factors known to affect medication effectiveness and safety. PMID:26226330

    Age-related macular degeneration (AMD) is one of the main socioeconomical health issues worldwide. AMD has a multifactorial etiology with a variety of risk factors. Smoking is the most important modifiable risk factor for AMD development and progression. The present review summarizes the epidemiological studies evaluating the association between smoking and AMD, the mechanisms through which smoking induces damage to the chorioretinal tissues, and the relevance of advising patients to quit smoking for their visual health.

    Mc Auley, Mark T; Mooney, Kathleen M

    2015-01-01

    One of the greatest challenges in biology is to improve the understanding of the mechanisms which underpin aging and how these affect health. The need to better understand aging is amplified by demographic changes, which have caused a gradual increase in the global population of older people. Aging western populations have resulted in a rise in the prevalence of age-related pathologies. Of these diseases, cardiovascular disease is the most common underlying condition in older people. The dysregulation of lipid metabolism due to aging impinges significantly on cardiovascular health. However, the multifaceted nature of lipid metabolism and the complexities of its interaction with aging make it challenging to understand by conventional means. To address this challenge computational modeling, a key component of the systems biology paradigm is being used to study the dynamics of lipid metabolism. This mini-review briefly outlines the key regulators of lipid metabolism, their dysregulation, and how computational modeling is being used to gain an increased insight into this system.

  2. Sepsis in Old Age: Review of Human and Animal Studies

    PubMed Central

    Starr, Marlene E; Saito, Hiroshi

    2014-01-01

    Sepsis is a serious problem among the geriatric population as its incidence and mortality rates dramatically increase with advanced age. Despite a large number of ongoing clinical and basic research studies, there is currently no effective therapeutic strategy that rescues elderly patients with severe sepsis. Recognition of this problem is relatively low as compared to other age-associated diseases. The disparity between clinical and basic studies is a problem, and this is likely due, in part, to the fact that most laboratory animals used for sepsis research are not old while the majority of sepsis cases occur in the geriatric population. The objective of this article is to review recent epidemiological studies and clinical observations, and compare these with findings from basic laboratory studies which have used aged animals in experimental sepsis.

  3. The influences of age on olfaction: a review

    Doty, Richard L.; Kamath, Vidyulata

    2014-01-01

    Decreased olfactory function is very common in the older population, being present in over half of those between the ages of 65 and 80 years and in over three quarters of those over the age of 80 years. Such dysfunction significantly influences physical well-being and quality of life, nutrition, the enjoyment of food, as well as everyday safety. Indeed a disproportionate number of the elderly die in accident gas poisonings each year. As described in this review, multiple factors contribute to such age-related loss, including altered nasal engorgement, increased propensity for nasal disease, cumulative damage to the olfactory epithelium from viral and other environmental insults, decrements in mucosal metabolizing enzymes, ossification of cribriform plate foramina, loss of selectivity of receptor cells to odorants, changes in neurotransmitter and neuromodulator systems, and neuronal expression of aberrant proteins associated with neurodegenerative disease. It is now well established that decreased smell loss can be an early sign of such neurodegenerative diseases as Alzheimer's disease and sporadic Parkinson's disease. In this review we provide an overview of the anatomy and physiology of the aging olfactory system, how this system is clinically evaluated, and the multiple pathophysiological factors that are associated with its dysfunction.

    Aims/hypothesis Individuals with heterozygous activating mutations of the KCNJ11 gene encoding a subunit of the ATP-sensitive potassium channel (KATP) can usually be treated with oral sulfonylurea (SU) pills in lieu of insulin injections. The aim of this study was to test our hypothesis that younger age at the time of initiation of SU therapy is correlated with lower required doses of SU therapy, shorter transition time and decreased likelihood of requiring additional diabetes medications. Methods We performed a retrospective cohort study using data on 58 individuals with neonatal diabetes due to KCNJ11mutations identified through the University of Chicago Monogenic Diabetes Registry (http://monogenicdiabetes.uchicago.edu/registry). We assessed the influence of age at initiation of SU therapy on treatment outcomes. Results HbA1c fell from an average of 8.5% (69 mmol/mol) before transition to 6.2% (44 mmol/mol) after SU therapy (p < 0.001). Age of initiation of SU correlated with the dose (mg kg−1 day−1) of SU required at follow-up (r = 0.80, p < 0.001). Similar associations were observed across mutation subtypes. Ten participants required additional glucose-lowering medications and all had initiated SU at age 13 years or older. No serious adverse events were reported. Conclusions/interpretation Earlier age at initiation of SU treatment is associated with improved response to SU therapy. Declining sensitivity to SU may be due to loss of beta cell mass over time in those treated with insulin. Our data support the need for early genetic diagnosis and appropriate personalised treatment in all cases of neonatal diabetes. PMID:25877689

  14. Aging in bacteria, immortality or not-a critical review.

    PubMed

    Gómez, José M G

    2010-12-01

    Bacteria were traditionally thought to have a symmetrical binary fission without a clear distinction between soma and germ-line, being thus considered as immortal biological entities. Yet it has been recently described that bacteria also undergo replicative aging (RA). That is, they exhibit finite replicative abilities under good conditions to growth. The apparently initial indistinguishability of sibling cells after cytokinesis is broken. After division, the daughter cell that inherits the "old" pole present in the "mother cell" progressively exhibits a decline in its proliferative capacity with increasing cell pole age. This is a clear hallmark and phenotypic manifestation of a bona fide RA phenomenon in toto. While the exact molecular mechanism(s) underlying to this lost of replicative potential are not yet fully understood, the "old pole cell" is considered as an aging parent that in a repeatedly manner is able to produce rejuvenated offspring which inherit a resetting of the biological clock. On the order hand, bacteria exhibit in addition to this "mandatory" RA the dubbed conditional senescence (CS). CS is defined as a decline in cellular viability observed in arrested-growing bacteria populations, a phenomenon apparently not related to RA under growing active conditions. To understand bacterial aging, it is necessary to put it within the sociality-multicellularity framework. This is a new conceptual paradigm that expresses the natural reality of the bacterial world. From this more ecological perspective these bacterial aging phenomena probably should represent an insurance/bethedging anticipative survival strategy. This is underpinned in a self-generation of an appropriate level of populational phenotypic diversity. That is, bacterial aging could be considered a communitarian adaptive response to cope with different environmental stresses and threats. I have highlighted the necessity to construct an integrative conceptual framework to achieve a unified view

    2016-01-01

    Leprosy is a chronic infectious disease caused by Mycobacterium leprae, representing a public health issue in some countries. Though more prevalent in adults, the detection of new cases in children under 15 years of age reveals an active circulation of bacillus, continued transmission and lack of disease control by the health system, as well as aiding in the monitoring of the endemic. Among patients under 15 years of age, the most affected age group is children between 10 and 14 years of age, although cases of patients of younger than 1 year of age have also been reported. Household contacts are the primary source of infection, given that caretakers, such as babysitters and others, must be considered in this scenario. Paucibacillary forms of the disease prevailed, especially borderline-tuberculoid leprosy, with a single lesion in exposed areas of the body representing the main clinical manifestation. Reactional states: Lepra reactions are rare, although some authors have reported high frequencies of this phenomenon, the most frequent of which is Type 1 Lepra Reaction. Peripheral nerve involvement has been described at alarming rates in some studies, which increases the chance of deformities, a serious problem, especially if one considers the age of these patients. The protective effect of BCG vaccination was found in some studies, but no consensus has been reached among different authors. Children must receive the same multidrug therapy regimen and the doses should, ideally, be calculated based on the child´s weight. Adverse reactions to this therapy are rare within this age group. This article aims to review epidemiological, clinical, and therapeutic aspects of leprosy in patients under 15 years of age. PMID:27192519

  20. Can Aging in Place Be Cost Effective? A Systematic Review

    PubMed Central

    Graybill, Erin M.; McMeekin, Peter; Wildman, John

    2014-01-01

    Purpose of the Study To systematically review cost, cost-minimization and cost-effectiveness studies for assisted living technologies (ALTs) that specifically enable older people to ‘age in place’ and highlight what further research is needed to inform decisions regarding aging in place. Design People aged 65+ and their live-in carers (where applicable), using an ALT to age in place at home opposed to a community-dwelling arrangement. Methods Studies were identified using a predefined search strategy on two key economic and cost evaluation databases NHS EED, HEED. Studies were assessed using methods recommended by the Campbell and Cochrane Economic Methods Group and presented in a narrative synthesis style. Results Eight eligible studies were identified from North America spread over a diverse geographical range. The majority of studies reported the ALT intervention group as having lower resource use costs than the control group; though the low methodological quality and heterogeneity of the individual costs and outcomes reported across studies must be considered. Implications The studies suggest that in some cases ALTs may reduce costs, though little data were identified and what there were was of poor quality. Methods to capture quality of life gains were not used, therefore potential effects on health and wellbeing may be missed. Further research is required using newer developments such as the capabilities approach. High quality studies assessing the cost-effectiveness of ALTs for ageing in place are required before robust conclusion on their use can be drawn. PMID:25058505

  1. Aging hemostasis: changes to laboratory markers of hemostasis as we age - a narrative review.

    PubMed

    Favaloro, Emmanuel J; Franchini, Massimo; Lippi, Giuseppe

    2014-09-01

    The incidence of venous thromboembolism (VTE) is well recognized to increase with aging. Concurrently, the plasma concentrations of many coagulation factors (e.g., fibrinogen, factor [F] V, FVII, FVIII, and FIX) increase with aging, as does von Willebrand factor (VWF), thrombin generation, and platelet activation. Data are conflicting regarding age-related changes in the natural anticoagulants, including protein C, protein S, and antithrombin. Changes are also observed with components of the fibrinolytic pathway. All in all, aging is associated with a variety of hemostasis changes that on balance reflects a heightened procoagulant status compared with earlier age. It has to be recognized that as this occurs in the otherwise normal general population, this can also be considered a normal phenomenon of progressive life. An element of this heightened procoagulant status may reflect ongoing inflammatory processes, given some markers, notably FVIII and fibrinogen, are acute phase reactants. A variety of acquired prothrombotic risk factors (e.g., cancer, autoimmune disorders, and diabetes) also gradually develop with aging, some of which may induce profound abnormalities of hemostasis, and confound the age-related changes in hemostasis, as well as their influence on thrombotic risk. In this article, we review the changes in hemostasis markers measurable within many hemostasis laboratories, and consider many of the important implications for clinical and laboratory practice. Apart from representing an increased thrombotic risk, additional considerations entail the potential need (1) to utilize age-adjusted normal ranges (e.g., for D-dimer), (2) to consider the consequence on previous diagnoses (e.g., "mild type 1" von Willebrand disease [VWD], where VWF test results may "normalize" with aging), and (3) to consider the effect of these changes of risk factors on the (perceived) therapeutic efficacy of antithrombotic medications such as aspirin.

  5. Dietary restriction of rodents decreases aging rate without affecting initial mortality rate -- a meta-analysis.

    PubMed

    Simons, Mirre J P; Koch, Wouter; Verhulst, Simon

    2013-06-01

    Dietary restriction (DR) extends lifespan in multiple species from various taxa. This effect can arise via two distinct but not mutually exclusive ways: a change in aging rate and/or vulnerability to the aging process (i.e. initial mortality rate). When DR affects vulnerability, this lowers mortality instantly, whereas a change in aging rate will gradually lower mortality risk over time. Unraveling how DR extends lifespan is of interest because it may guide toward understanding the mechanism(s) mediating lifespan extension and also has practical implications for the application of DR. We reanalyzed published survival data from 82 pairs of survival curves from DR experiments in rats and mice by fitting Gompertz and also Gompertz-Makeham models. The addition of the Makeham parameter has been reported to improve the estimation of Gompertz parameters. Both models separate initial mortality rate (vulnerability) from an age-dependent increase in mortality (aging rate). We subjected the obtained Gompertz parameters to a meta-analysis. We find that DR reduced aging rate without affecting vulnerability. The latter contrasts with the conclusion of a recent analysis of a largely overlapping data set, and we show how the earlier finding is due to a statistical artifact. Our analysis indicates that the biology underlying the life-extending effect of DR in rodents likely involves attenuated accumulation of damage, which contrasts with the acute effect of DR on mortality reported for Drosophila. Moreover, our findings show that the often-reported correlation between aging rate and vulnerability does not constrain changing aging rate without affecting vulnerability simultaneously.

    Community-acquired pneumonia (CAP) remains a force to reckon with, as it accounts for 1.1 million of all deaths in children less than 5 years of age globally, with disproportionately higher mortality occurring in the low and middle income-countries (LMICs) of Southeast Asia and Africa. Existing strategies to curb pneumonia-related morbidity and mortality have not effectively translated into meaningful control of pneumonia-related burden. In the present systematic review, we conducted a meta-analysis of trials conducted in LMICs to determine the most suitable antibiotic therapy for treating pneumonia (very severe, severe and non-severe). While previous reviews, including the most recent review by Lodha et al, have focused either on single modality of antibiotic therapy (such as choice of antibiotic) or children under the age of 16 years, the current review updates evidence on the choice of drug, duration, route and combination of antibiotics in children specifically between 2 and 59 months of age. We included randomised controlled trials (RCTs) and quasi-RCTs that assessed the route, dose, combination and duration of antibiotics in the management of WHO-defined very severe/severe/non-severe CAP. Study participants included children between 2 and 59 months of age with CAP. All available titles and abstracts were screened for inclusion by two review authors independently. All data was entered and analysed using Review Manager 5 software. The review identified 8122 studies on initial search, of which 22 studies which enrolled 20,593 children were included in meta-analyses. Evidence from these trials showed a combination of penicillin/ampicillin and gentamicin to be effective for managing very severe pneumonia in children between 2 and 59 months of age, and oral amoxicillin to be equally efficacious, as other parenteral antibiotics for managing severe pneumonia in children of this particular age group. Oral amoxicillin was also found to be effective in non

  7. Relaxation and physical aging in network glasses: a review

    Recent progress in the description of glassy relaxation and aging are reviewed for the wide class of network-forming materials such as GeO2, Ge x Se1‑x , silicates (SiO2–Na2O) or borates (B2O3–Li2O), all of which have an important usefulness in domestic, geological or optoelectronic applications. A brief introduction of the glass transition phenomenology is given, together with the salient features that are revealed both from theory and experiments. Standard experimental methods used for the characterization of the slowing down of the dynamics are reviewed. We then discuss the important role played by aspects of network topology and rigidity for the understanding of the relaxation of the glass transition, while also permitting analytical predictions of glass properties from simple and insightful models based on the network structure. We also emphasize the great utility of computer simulations which probe the dynamics at the molecular level, and permit the calculation of various structure-related functions in connection with glassy relaxation and the physics of aging which reveal the non-equilibrium nature of glasses. We discuss the notion of spatial variations of structure which leads to the concept of ‘dynamic heterogeneities’, and recent results in relation to this important topic for network glasses are also reviewed.

    We have used an embedded electromagnetic particle velocity gauge technique to measure the shock initiation behavior in PBX 9501 explosive. Up to twelve separate particle velocity wave profile measurements have been made at different depths in a single experiment. These detail the growth from an input shock to a detonation. In addition, another gauge element called a ''shock tracker'' has been used to monitor the progress of the shock front as a function of time and position as it moves through the explosive sample. This provides data similar to that obtained in a traditional explosively driven wedge test and is used to determine the position and time that the wave attains detonation. Run distance-to-detonation vs. input pressure (Pop-plot) data and particle velocity wave profile data have been obtained on new PBX 9501 pressed to densities of 1.826, 1.830, and 1.837 g/cm{sup 3}. In addition, the same measurements were performed on aged material recovered from dismantled W76 and W78 weapons. The input pressure range covered was 3.0 to 5.2 GPa. All results to date show shock sensitivity to be a function only of the initial density and not of age. PBX 9501 shock initiates the same after 17 years in stockpile as it does on the day it is pressed. Particle velocity wave profiles show mixed heterogeneous initiation (growth in the front) and homogeneous initiation (growth behind the front).

  9. Evaluation of the Mental Healthiness Aging Initiative: community program to promote awareness about mental health and aging issues.

    2012-04-01

    The objective of this study is to evaluate the Mental Healthiness Aging Initiative, designed to promote community awareness and knowledge about mental health and aging issues. This study occurred during 2007-2009 in 67 of 120 counties in Kentucky. A rural region (11 counties) received the intervention, consisting of focus groups, Extension Agent training, and television-based social marketing campaign. Partial-intervention counties (29 counties) received only the television-based social marketing campaign. The control counties (27 counties) received no intervention activities. Results indicated that the intervention counties agreed more with being able to assist elder adults with a potential mental illness. Also, the intervention counties understood the risk of consuming alcohol and medications better, but had a poorer recognition of drinking problems in elder adults. These findings need to be considered within study limitations, such as measurement error, degree of intervention exposure, and regional differences across intervention groups. The study demonstrates that community interventions on mental health awareness and knowledge are feasible within majority rural regions, with Extension Agents being gatekeepers, for promoting positive messages about mental health and aging issues.

  19. Repetition priming in normal aging and Alzheimer's disease: a review of findings and theories.

    PubMed

    Fleischman, D A; Gabrieli, J D

    1998-03-01

    On repetition priming tasks, memory is measured indirectly as a change in performance due to recent experience. It is often functionally and neurally dissociated from performance on explicit memory tasks, which directly measure conscious recall or recognition of recent events. Repetition priming has therefore been extensively studied in normal aging and Alzheimer's disease, which feature mild to severe changes in explicit memory. Initial studies indicated that repetition priming was immune to the effects of aging and greatly reduced in Alzheimer's disease (AD). As more studies have been performed, however, these initial conclusions appear less clear than before and, in the case of AD, actually misleading. The purpose of this article is to provide a comprehensive review of this rapidly expanding literature, articulate the issues that are critical to interpreting the empirical results, and discuss what new conclusions are suggested by the overall pattern of findings.

    As the population ages, the need for effective methods to maintain or even improve older adults’ cognitive performance becomes increasingly pressing. Here we provide a brief review of the major intervention approaches that have been the focus of past research with healthy older adults (strategy training, multi-modal interventions, cardiovascular exercise, and process-based training), and new approaches that incorporate neuroimaging. As outcome measures, neuroimaging data on intervention-related changes in volume, structural integrity, and functional activation can provide important insights into the nature and duration of an intervention's effects. Perhaps even more intriguingly, several recent studies have used neuroimaging data as a guide to identify core cognitive processes that can be trained in one task with effective transfer to other tasks that share the same underlying processes. Although many open questions remain, this research has greatly increased our understanding of how to promote successful aging of cognition and the brain. PMID:19876740

    According to World Health Organization older individuals is the fastest growing age-group around the globe, thanks to the tremendous improvements in medical and pharmaceutical therapies, as well as in quality of life. Unfortunately, this raise in life span is accompanied by significant increase in disease burden, and consequent economical costs. Lifestyle modifications and effective prevention strategies have shown considerable benefits as regards the development of age-oriented chronic diseases. Among lifestyle factors, nutrition is a key component for achieving good health. Nevertheless, this parameter has insufficiently been investigated in older people. This is a rather important scientific gap, considering the westernization of nutritional habits observed the last few decades, with high red meat consumption and its processed products being an indispensable part. Moreover, its adverse impact in cardiovascular disease and cancer has been extensively investigated, while in recent literature, interest has been remarkably oriented towards its subtypes (i.e., fresh and processed); however, outcomes as regards the older population are controversial with a variety of them proposing moderation of red meat mainly the processed type, whilst others recognizing fresh red meat, especially the lean type, an important source of high quality protein so as to manage muscle tissue loss, a common implication of advanced-age discount. The aim of the present review was to present an overview of studies which have investigated the association between red meat and its subtypes, with chronic diseases, in middle and advanced age individuals.

    Rejuvenative procedures of the face are increasing in numbers, and a plethora of different therapeutic options are available today. Every procedure should aim for the patient's safety first and then for natural and long-lasting results. The face is one of the most complex regions in the human body and research continuously reveals new insights into the complex interplay of the different participating structures. Bone, ligaments, muscles, fat, and skin are the key players in the layered arrangement of the face.Aging occurs in all involved facial structures but the onset and the speed of age-related changes differ between each specific structure, between each individual, and between different ethnic groups. Therefore, knowledge of age-related anatomy is crucial for a physician's work when trying to restore a youthful face.This review focuses on the current understanding of the anatomy of the human face and tries to elucidate the morphological changes during aging of bone, ligaments, muscles, and fat, and their role in rejuvenative procedures.

    2016-10-01

    In developed countries the prevalence of protein-energy malnutrition increases with age and multi-morbidities increase nutritional risk in aged care residents in particular. This paper presents a narrative review of the current literature on the identification, prevalence, associated risk factors, consequences, and management of malnutrition in the residential aged care (RAC) setting. We performed searches of English-language publications on Medline, PubMed, Ovid and the Cochrane Library from January 1, 1990 to November 25, 2015. We found that, on average, half of all residents in aged care are malnourished as a result of factors affecting appetite, dietary intake and nutrient absorption. Malnutrition is associated with a multitude of adverse outcomes, including increased risk of infections, falls, pressure ulcers and hospital admissions, all of which can lead to increased health care costs and poorer quality of life. A number of food and nutrition strategies have demonstrated positive nutritional and clinical outcomes in the RAC setting. These strategies extend beyond simply enhancing the nutritional value of foods and hence necessitate the involvement of a range of committed stakeholders. Implementing a nutritional protocol in RAC facilities that comprises routine nutrition screening, assessment, appropriate nutrition intervention, including attention to food service systems, and monitoring by a multidisciplinary team can help prevent decline in residents' nutritional status. Food and nutritional issues should be identified early and managed on admission and regularly in the RAC setting. PMID:27621242

  12. Role of OH-initiated oxidation of isoprene in aging of combustion soot.

    2013-03-01

    We have investigated the contribution of OH-initiated oxidation of isoprene to the atmospheric aging of combustion soot. The experiments were conducted in a fluoropolymer chamber on size-classified soot aerosols in the presence of isoprene, photolytically generated OH, and nitrogen oxides. The evolution in the mixing state of soot was monitored from simultaneous measurements of the particle size and mass, which were used to calculate the particle effective density, dynamic shape factor, mass fractal dimension, and coating thickness. When soot particles age, the increase in mass is accompanied by a decrease in particle mobility diameter and an increase in effective density. Coating material not only fills in void spaces, but also causes partial restructuring of fractal soot aggregates. For thinly coated aggregates, the single scattering albedo increases weakly because of the decreased light absorption and practically unchanged scattering. Upon humidification, coated particles absorb water, leading to an additional compaction. Aging transforms initially hydrophobic soot particles into efficient cloud condensation nuclei at a rate that increases in the presence of nitrogen oxides. Our results suggest that ubiquitous biogenic isoprene plays an important role in aging of anthropogenic soot, shortening its atmospheric lifetime and considerably altering its impacts on air quality and climate.

    Laboratory experiments are conducted to investigate aging of size-classified black carbon (BC) particles from OH-initiated oxidation of m-xylene. The variations in the particle size, mass, effective density, morphology, optical properties, hygroscopicity, and activation as cloud condensation nuclei (CCN) are simultaneously measured by a suite of aerosol instruments, when BC particles are exposed to the oxidation products of the OH-m-xylene reactions. The BC aging is governed by the coating thickness (Δrve), which is correlated to the reaction time and initial concentrations of m-xylene and NOx. For an initial diameter of 100 nm and Δrve = 44 nm, the particle size and mass increase by a factor of 1.5 and 10.4, respectively, and the effective density increases from 0.43 to 1.45 g cm(-3) due to organic coating and collapsing of the BC core. The BC particles are fully converted from a highly fractal to nearly spherical morphology for Δrve = 30 nm. The scattering, absorption, and single scattering albedo of BC particles are enhanced accordingly with organic coating. The critical supersaturation for CCN activation is reduced to 0.1% with Δrve = 44 nm. The results imply that the oxidation of m-xylene exhibits larger impacts in modifying the BC particle properties than those for the OH-initiated oxidation of isoprene and toluene. PMID:27384756

    Development of optimized pediatric formulations for oral administration can be challenging, time consuming, and financially intensive process. Since its inception, the biopharmaceutical classification system (BCS) has facilitated the development of oral drug formulations destined for adults. At least theoretically, the BCS principles are applied also to pediatrics. A comprehensive age-appropriate BCS has not been fully developed. The objective of this work was to provisionally classify oral drugs listed on the latest World Health Organization's Essential Medicines List for Children into an age-appropriate BCS. A total of 38 orally administered drugs were included in this classification. Dose numbers were calculated using age-appropriate initial gastric volume for neonates, 6-month-old infants, and children aging 1 year through adulthood. Using age-appropriate initial gastric volume and British National Formulary age-specific dosing recommendations in the calculation of dose numbers, the solubility classes shifted from low to high in pediatric subpopulations of 12 years and older for amoxicillin, 5 years, 12 years and older for cephalexin, 9 years and older for chloramphenicol, 3-4 years, 9-11 and 15 years and older for diazepam, 18 years and older (adult) for doxycycline and erythromycin, 8 years and older for phenobarbital, 10 years and older for prednisolone, and 15 years and older for trimethoprim. Pediatric biopharmaceutics are not fully understood where several knowledge gaps have been recently emphasized. The current biowaiver criteria are not suitable for safe application in all pediatric populations. PMID:26935428

    2015-06-01

    One of the potential etiologies for non-familial Neurofibromatosis Type 1 (NF1) is increasing parental age. We sought to evaluate recent evidence for parental age effects in NF1 in a large study. Individuals with NF1 and a comparison group from the U.S. general population born between 1994 and 2012 were ascertained from the NF1 Patient Registry Initiative (NPRI) and the National Center for Vital Statistics, respectively. Multiple linear regression analysis was employed to identify differences between familial NF1, non-familial NF1, and U.S. population subjects in the mean parental ages at the time of the birth of offspring in each group. In addition, we also evaluated the effect of parental age on NF1 offspring with and without a pediatric brain tumor history. A total of 313 subjects from the NPRI (including 99 brain tumor cases) matched by birth year at a 1:3 ratio to U.S. general population births (n = 939) were included. Compared to the U.S. general population and familial NF1 cases, the mean paternal age for non-familial NF1 cases was 4.34 years (95% CI 3.23-5.46, p ≤ 0.0001) and 3.39 years (95% CI 1.57-5.20, p ≤ 0.0001) older, respectively, after adjusting for birth year. A similar pattern was observed for maternal age. There were no statistically significant differences in the mean maternal or paternal ages between NF1 offspring with and without a pediatric brain tumor. In conclusion, these data support a parental age effect for non-familial NF1 cases, but not for pediatric brain tumors in NF1. PMID:25523354

    Ageing is associated with structural and functional changes of the skin that result in increased vulnerability. The aim of this systematic review is to synthesize empirical evidence about the efficacy and effectiveness of basic skin care interventions for maintaining skin integrity in the aged. The databases Medline, EMBASE, CINAHL (1990-2012), Scopus, SCI (February 2013) and reference lists were searched. Inclusion criteria were primary intervention studies using skin care products in physiologically aged skin (lower age limit 50 years). Study and sample characteristics, interventions and outcomes were extracted. The methodological quality was assessed and a level of evidence was assigned. From 1535 screened articles 188 were read in full text. From these, 33 articles were included reporting results on treating dry skin conditions, and preventing incontinence-associated dermatitis and superficial ulcerations. Most studies had lower levels of evidence of 3 or 4. Skin-cleansing products containing syndets or amphoteric surfactants compared with standard soap and water washing improved skin dryness and demonstrated skin-protecting effects. Moisturizers containing humectants consistently showed statistically significant improvements in skin dryness. Skin barrier products containing occlusives reduced the occurrence of skin injuries compared with standard or no treatment. Owing to methodological limitations the current evidence base for basic skin care in the aged is weak. Using low-irritating cleansing products and humectant- or occlusive-containing moisturizers seems to be the best strategy for maintaining the skin barrier function and integrity. We know little about the effects of cleansing regimens and about the benefits of moisturizers when compared with each other. PMID:23773110

    Significant advances in health and social wellbeing have led to linear gains in life expectancy and an accompanying increase in the burden imposed by age-related morbidities. Complex alterations in hormonal networks which regulate homeostasis and survival may underlie this poor adaptation to later life, as exemplified by an increased fracture risk amongst post-menopausal women. Beyond overt under- or overactivity of hormonal axes, changes in the concentrations of regulatory hormones may also impact on health and disease. Subclinical hyperthyroidism, a disorder characterised by normal thyroxine levels in the presence of decreased thyroid-stimulating hormone, is, for instance, independently associated with an increased risk of atrial fibrillation amongst elderly populations. Both the menopause and subclinical thyroid disease demonstrate the difficulty in reversing endocrine changes in later life, with minimal impact from thyroxine therapy in subclinical hypothyroidism and multiple reports of harm resulting from hormone replacement therapy in peri- and post-menopausal women. Given these findings, strategies to locally regulate hormone bioavailability by altering pre-receptor metabolism may offer greater therapeutic potential in the fight against age-related disease. This review aims to provide an overview of the ageing endocrine system and its potential impact on health and disease in the elderly. It will postulate that strategies to coordinate pre-receptor hormone metabolism and a greater understanding of putative hormonal longevity pathways may offer key new drug targets in the fight against ageing, and will argue against applying the conventional endocrine maxim of 'block and replace' to hormonal changes seen during ageing.

    This review presents critical literature on effects of humidity and temperature on the properties of natural fibres and its composites. The drawback of moisture absorption on the mechanical properties of natural fibre and its composites is evaluated. Numerous researchers have been working to address the moisture absorption issue, with specific attention paid to the surface treatment of fibres and refining the fibre-matrix interface. Because of the natural fibre's positive commercial and environmental outcomes, as well as their desirable properties such as high specific strength, natural fibre reinforced composites are displaying a good potential to be used in various applications such as automotive, aerospace and packaging. This review addresses a comprehensive survey on hygroscopic factors (long term environmental aging) affecting natural fibres and their performance as reinforcement in polymer composites. The effects of cellulose surface chemistry and topography on hydrophobicity are addressed. Furthermore, the review also addresses the progress in the development of superhydrophobic materials based on cellulose material for better moisture resistance. In addition, recent investigations dealing with bio-based coatings prepared from renewable resources are also discussed. PMID:26256193

    This report is the first milestone report for the actinic mask blank inspection project conducted at the VNL, which forms sub-section 3 of the Q1 2003 mask blank technology transfer program at the VNL. Specifically this report addresses deliverable 3.1.1--design review and preliminary tool design. The goal of this project is to design an actinic mask inspection tool capable of operating in two modes: high-speed scanning for the detection of multilayer defects (inspection mode), and a high-resolution aerial image mode in which the image emulates the imaging illumination conditions of a stepper system (aerial image or AIM mode). The purpose and objective of these two modes is as follows: (1) Defect inspection mode--This imaging mode is designed to scan large areas of the mask for defects EUV multilayer coatings. The goal is to detect the presence of multilayer defects on a mask blank and to store the co-ordinates for subsequent review in AIM mode, thus it is not essential that the illumination and imaging conditions match that of a production stepper. Potential uses for this imaging mode include: (a) Correlating the results obtained using actinic inspection with results obtained using other non-EUV defect inspection systems to verify that the non-EUV scanning systems are detecting all critical defects; (b) Gaining sufficient information to associate defects with particular processes, such as various stages of the multilayer deposition or different modes of operation of the deposition tool; and (c) Assessing the density and EUV impact of surface and multilayer anomalies. Because of the low defect density achieved using current multilayer coating technology it is necessary to be able to efficiently scan large areas of the mask in order to obtain sufficient statistics for use in cross-correlation experiments. Speed of operation as well as sensitivity is therefore key to operation in defect inspection mode. (2) Aerial Image Microscope (AIM) mode--In AIM mode the tool is

    Telomere length shortens with aging, and short telomeres have been linked to a wide variety of pathologies. Previous studies suggested a discrepancy in age-associated telomere shortening rate estimated by cross-sectional studies versus the rate measured in longitudinal studies, indicating a potential bias in cross-sectional estimates. Intergenerational changes in initial telomere length, such as that predicted by the previously described effect of a father’s age at birth of his offspring (FAB), could explain the discrepancy in shortening rate measurements. We evaluated whether changes occur in initial telomere length over multiple generations in three large datasets and identified paternal birth year (PBY) as a variable that reconciles the difference between longitudinal and cross-sectional measurements. We also clarify the association between FAB and offspring telomere length, demonstrating that this effect is substantially larger than reported in the past. These results indicate the presence of a downward secular trend in telomere length at birth over generational time with potential public health implications. PMID:25952108

    Atherosclerotic cardiovascular disease (CVD) is a collective term comprising of a group of disorders of the heart and blood vessels. These diseases are the largest cause of morbidity and premature death worldwide. Coronary heart disease and cerebrovascular disease (stroke) are the most frequently occurring diseases. The two major initiators involved in the development of atherosclerotic CVD are vascular production of reactive oxygen species (ROS) and lipid oxidation. In atherosclerosis development, ROS is associated with rapid loss of anti-inflammatory and anti-atherogenic activities of the endothelium-derived nitric oxide (NO(·)) resulting in endothelial dysfunction. In part involving activation of the transcription factor NF-κB, ROS have been involved in signaling cascades leading to vascular pro-inflammatory and pro-thrombotic gene expression. ROS is also a potent activator of matrix metalloproteinases (MMPs), which indicate plaque destabilization and rupture. The second initiator involved in atherosclerotic CVD is the oxidation of low-density lipoproteins (LDL). Oxidation of LDL in vessel wall leads to an inflammatory cascade that activates atherogenic pathway leading to foam cell formation. The accumulation of foam cells leads to fatty streak formation, which is the earliest visible atherosclerotic lesion. In contrast, the cardiac sarco/endoplasmic reticulum Ca(2+)-ATPase (SERCA2a) and hepatic apolipoprotein E (apoE) expression can improve cardiovascular function. SERCA2a regulates the cardiac contractile function by lowering cytoplasmic calcium levels during relaxation, and affecting NO(·) action in vascular cells, while apoE is a critical ligand in the plasma clearance of triglyceride- and cholesterol-rich lipoproteins.

    A substantial amount of evidence suggests that collegiate and elite athletes involved in weight-sensitive sports are at greater risk of developing eating disorders (EDs) than the general population. With the limited effectiveness of treatment for EDs, prevention of EDs has been broadly considered in the literature. The present paper reviewed the existing literature on ED prevention programmes for athletes in order to determine the current status of prevention programmes and recommend future directions. The available literature suggests that selective, primary interventions with multiple targets and an interactive multimodal approach appear most effective. Current challenges in the field, including lack of longitudinal research, hesitation by the sport community to be involved in ED research and poor cross-field communication and collaboration, are also explored. The lack of dissemination of evidence-based prevention programmes and the simultaneous promotion of prevention programmes that have not yet been empirically examined are also discussed. Based on these observations future directions are recommended. PMID:25815432

    Introduction Studies suggest students who are substantially older than the average age for their grade engage in risky health behaviors, including substance use. However, most studies do not account for the distinct reasons why students are old for their grade (ie, grade retention vs delayed school entry) or for their pubertal stage. Thus, whether the association between age for grade and substance use is confounded by these factors is unknown. We sought to determine whether age, grade, or pubertal stage were associated with early substance use. Methods Cross-sectional Healthy Passages Wave I survey data from 5,147 fifth graders and their caregivers in Alabama, California, and Texas from 2004 through 2006 were analyzed in 2014. Logistic regressions examined whether older age for grade, grade retention, delayed school entry, or pubertal stage were associated with use of any substance, cigarettes, alcohol, or other drugs. Results Seventeen percent of fifth graders reported trying at least 1 substance. Among boys, advanced pubertal stage was associated with increased odds of cigarette, alcohol, or other drug use, whereas delayed school entry was associated with lower odds of any substance, alcohol, or other drug use. Among girls, advanced pubertal stage was associated only with higher odds of alcohol use, and delayed school entry was not associated with substance use. Neither older age for grade or grade retention was independently associated with substance use after controlling for potential confounders. Conclusion Advanced pubertal stage may be a more important risk factor for substance use than age for grade. Pediatricians should consider initiating substance use screening earlier for patients with advanced pubertal stage. PMID:26583575

    The epimerization of amino acid residues increases with age in living organisms. In the present study, the structural consequences and thermodynamic functions of the epimerization of thymopentin (TP-5), the active site of the thymic hormone thymopoietin, were studied using molecular dynamics and density functional theory methods. The results show that free radical-initiated D-amino acid formation is energetically favoured (-130 kJmol-1) for each residue and induces significant changes to the peptide structure. In comparison to the wild-type (each residue in the L-configuration), the radius of gyration of the D-Asp3 epimer of the peptide decreased by 0.5 Å, and disrupted the intramolecular hydrogen bonding of the native peptide. Beyond establishing important structural, energetic and thermodynamic benchmarks and reference data for the structure of TP-5, these results disseminate the understanding of molecular ageing, the epimerization of amino acid residues.

  9. Review: Cerebral microvascular pathology in aging and neurodegeneration

    2010-01-01

    This review of age-related brain microvascular pathologies focuses on topics studied by this laboratory, including anatomy of the blood supply, tortuous vessels, venous collagenosis, capillary remnants, vascular density, and microembolic brain injury. Our studies feature thick sections, large blocks embedded in celloidin, and vascular staining by alkaline phosphatase (AP). This permits study of the vascular network in three dimensions, and the differentiation of afferent from efferent vessels. Current evidence suggests that there is decreased vascular density in aging, Alzheimer’s disease (AD), and leukoaraiosis (LA), and cerebrovascular dysfunction precedes and accompanies cognitive dysfunction and neurodegeneration. A decline in cerebrovascular angiogenesis may inhibit recovery from hypoxia-induced capillary loss. Cerebral blood flow (CBF) is inhibited by tortuous arterioles and deposition of excessive collagen in veins and venules. Misery perfusion due to capillary loss appears to occur before cell loss in LA, and CBF is also reduced in the normal-appearing white matter. Hypoperfusion occurs early in AD, inducing white matter lesions and correlating with dementia. In vascular dementia, cholinergic reductions are correlated with cognitive impairment, and cholinesterase inhibitors have some benefit. Most lipid microemboli from cardiac surgery pass through the brain in a few days, but some remain for weeks. They can cause what appears to be a type of vascular dementia years after surgery. Donepezil has shown some benefit. Emboli, such as clots, cholesterol crystals, and microspheres can be extruded through the walls of cerebral vessels, but there is no evidence yet that lipid emboli undergo such extravasation.

    2009-01-01

    Background Aging can be thought of as the collision between destructive processes that act on cells and organs over the lifetime and the responses that promote homeostasis, vitality and longevity. However, the precise mechanisms that determine the rates of aging in organisms are not known. Objective Macromolecules such as proteins are continuously exposed to potential damaging agents that can cause loss of molecular function and depletion of cell populations over the lifetime of essential organs. One of the key homeostatic responses involved in maintaining longevity is the induction of heat shock proteins (HSPs), a conserved reaction to damaged intracellular proteins. We aim to discuss how the interplay between protein damage and its repair or removal from the cell may influence longevity and aging. Methods We have reviewed experiments carried out in mammalian and non-mammalian organisms on molecular chaperones and the transcription factor (heat shock factor 1, HSF1) responsible for their expression. We have discussed mechanisms through which these molecules are regulated in cells, respond to stimuli that enhance longevity and become impaired during aging. Results The transcription factor HSF1 initiates the prolific induction of HSP when cells are exposed to protein damage. HSPs are molecular chaperones that protect the proteome by folding denatured polypeptides and promoting the degradation of severely damaged proteins. Activation of HSF1 is coupled functionally to fundamental pathways of longevity and orchestrates the evasion of aging through HSP induction and antagonism of protein aggregation. In addition to mediating protein quality control, some HSPs such as Hsp27 and Hsp70 directly protect cells against damage-induced entry into death pathways. However, the heat shock response declines in potency over the lifetime, and enfeeblement of the response contributes to aging by permitting the emergence of protein aggregation diseases, reduction in cellular vigor and

  13. Aging, circadian rhythms and depressive disorders: a review

    PubMed Central

    Campos Costa, Inês; Nogueira Carvalho, Hugo; Fernandes, Lia

    2013-01-01

    Introduction: Aging is typically associated with impairing behavioral patterns that are frequently and inappropriately seen as normal. Circadian rhythm changes and depressive disorders have been increasingly proposed as the two main overlapping and interpenetrating changes that take place in older age. This study aims to review the state of the art on the subject concerning epidemiology, pathophysiological mechanism, clinical findings and relevance, as well as available treatment options. Materials and Methods: A nonsystematic review of all English language PubMed articles published between 1995 and December 2012 using the terms “circadian rhythms”, “mood disorders”, “depression”, “age”, “aging”, “elderly” and “sleep”. Discussion and conclusion: Sleep disorders, mainly insomnia, and depression have been demonstrated to be highly co-prevalent and mutually precipitating conditions in the elderly population. There is extensive research on the pathophysiological mechanisms through which age conditions circadian disruption, being the disruption of the Melatonin system one of the main changes. However, research linking clearly and unequivocally circadian disruption and mood disorders is still lacking. Nonetheless, there are consistently described molecular changes on shared genes and also several proposed pathophysiological models linking depression and sleep disruption, with clinical studies also suggesting a bi-directional relationship between these pathologies. In spite of this suggested relation, clinical evaluation of these conditions in elderly patients consistently reveals itself rather complicated due to the frequently co-existing co-morbidities, some of them having been demonstrated to alter sleep and mood patters. This is the case of strokes, forms of dementia such as Alzheimer and Parkinson, several neurodegenerative disorders, among others. Although there are to the present no specific treatment guidelines, available treatment

  14. Star Formation in NGC 6531-Evidence From the age Spread and Initial Mass Function

    NASA Astrophysics Data System (ADS)

    Forbes, Douglas

    1996-09-01

    The results of a photometric UBV study of the young open cluster NGC 6531 are presented. The cluster is found to have a mean reddening E(B-V)=0.28±0.04 (s.d.) and distance modulus (V0-Mv)=10.70±0.13 (s.e.), and 105±11 likely cluster members have been identified within the cluster coronal radius of 9 arcmin. A comparison of the high-luminosity end of the cluster color-magnitude diagram to the evolutionary models by Maeder & Meynet [A&AS, 76, 411(1988)] suggests a nuclear age of (8±2) Myr. The very clear gap in the distribution of stars with 0≤(B-V)0≤0.20, corresponding to the "burn-off" of 3He in stars contracting to the main sequence [Ulrich, ApJ, 168, 57 (1971)], implies a contraction age of (8±3) Myr. There would seem to be no evidence of a spread in the ages of cluster stars, as has been observed in several other young open clusters [Herbst & Miller, AJ, 87, 1478 (1982)]. The initial mass function (IMF) constructed from the cluster luminosity function and the mass-luminosity relation given by Scab (1986) shows good agreement with the field star IMF, and with the IMFS of a number of clusters of similar age and richness. The relative deficiency of low-mass stars seen by Herbst and Miller in NGC 3293 (a cluster of quite similar age and reddening) is not evident in NGC 6531.

  18. Subduction Along the South Caribbean Deformed Belt: Age of Initiation and Backthrust Origin

    NASA Astrophysics Data System (ADS)

    Mann, P.; Kroehler, M.; Escalona, A.; Magnani, B.; Christeson, G.

    2007-12-01

    The South Caribbean deformed belt (SCDB) represents a submarine prism formed at the interface between subducting oceanic material in the Colombian and Venezuelan basins and arc terranes along the northern edge of the South American continent. The SCDB and subducted Caribbean slab extends 1500 km from Panama to the Aves Ridge and is similar in scale to better studied magmatic subduction zones in the Lesser Antilles and Central America. The age of subduction of the Venezuelan basin at the SCDB has been examined by dating asymmetrical sediment wedges inferred to have formed above the bending and subducting slab of the Venezuelan basin. Ages are constrained by ties to DSDP wells drilled in the Venezuelan basin ~150 km north of the SCDB. Onlapping wedges are oldest in the western area near the Beata Ridge (middle Eocene), of intermediate age in the central area (early Miocene), and youngest in the east near the Aves Ridge (Mio- Pleistocene). Overlying younger wedges in all areas demonstrate that subduction continued following its initiation. Similar ages of deformed syn-thurst wedges are known from the now inactive continental foreland of northern South America in a belt from western Venezuela to Trinidad. Based on this correlation, we propose a simple back arc thrusting origin for the SCDB that is analogous to the eastern Sunda arc of Indonesia. The obliquity of convergence in the Caribbean case has produced a longlived, eastwardly-migrating backthrust that contrasts to more static backthrust in Sunda. The immediate onset of backthrusting following continental collision means that South America-Caribbean convergence was accommodated by newly organized and focussed subduction at the SCDB backthrust; the "collided" crust of intervening accreted arc terranes remains remarkably unaffected by regional shortening effects.

  19. Initial insights into the age and origin of the Kubuqi sand sea of northern China

    NASA Astrophysics Data System (ADS)

    2016-04-01

    The Kubuqi Desert is the only active sand sea in the semiarid regions of northern China and occurs along the southern margin of the Yellow River. Little is known about the age and origin of this large (17,000 km2) sand sea with a present annual precipitation of 200-480 mm. Sand drift potentials indicated net capable winds for aeolian transport are from the northwest, though winds are stronger to north beyond the dune field than within the sand sea. Geomorphic and stratigraphic observations indicate that Holocene aeolian sand often drapes over bedrock and river terraces as a palimpsest landscape. Field investigations identified four stratigraphic sections with multiple aeolian sand units and palaeosols, with age control by optically stimulated luminescence (OSL) dating of quartz grains. Palaeosols are weakly developed, mostly accumulative A horizon with organic carbon content < 1% and reflect sand sheet deposition possibly in a steppe environment. Although sediments near river channels or former lakes might give old ages, the initial formation and age of the Kubuqi sand sea should be judged from the occurrence of the sandy palimpsest of the landscape that is OSL dated to the Holocene in general. The latest period of aeolian reactivation may be related to human activity associated with grazing and farming from lost cities in the Kubuqi Desert during the Han (206 B.C. - A.D. 220) and the Tang (A.D. 608 - 907) Dynasties. Also, variable discharge of the Yellow River with local diversions for irrigation and throughout the catchment resulted in possibly an increased supply of aeolian particles for dune field expansion in the past 2 ka.

    2015-01-01

    Objectives: Services provided to older people should be developed based on active ageing policies. Nutrition is one aspect of active ageing, but little is known about how food activities contribute to psychological well-being in later life. This is a systematic review of qualitative and quantitative research that answers the question ‘What is known about the relationship between food activities and the maintenance of identities in old age?’. Methods: We followed the preferred reporting items for systematic reviews and meta-analyses guidelines and used quality assessment parameters to complete a systematic review and narrative synthesis. Academic Search Premier, MEDLINE, CINAHL Plus, and PsycINFO databases were searched. Results: We initially identified 8016 articles, of which 167 full-text articles were screened for inclusion. Twenty-two articles were included in the review. There was moderate evidence from nine qualitative and two quantitative studies, of variable quality, that food activities contribute to the maintenance of women's gendered identities, the ethnic identities of men and women, and community identities. There was moderate evidence from 10 qualitative studies, of variable quality, that a change in food choice and deteriorating health changed food activity participation. These changes threatened identities. Most studies included both younger adults and older adults. Conclusion: In later life, there are many life experiences leading to change. Further research is needed to develop understanding of how identity and mental well-being are maintained, despite changes in everyday activities like cooking and eating. This may enable health care professionals to meet psychological needs alongside biological needs during nutritional interventions. PMID:25373998

    1994-03-01

    The underground storage tanks at the Hanford Complex contain wastes generated over many years from plutonium production and recovery processes, and mixed wastes from radiological degradation processes. The chemical changes of the organic materials used in the extraction processes have a direct bearing on several specific safety issues, including potential energy releases from these tanks. The major portion of organic materials that have been added to the tanks consists of tributyl phosphate, dibutyl phosphate, butyl alcohol, hexone (methyl isobutyl ketone), normal paraffin hydrocarbons (NPH), ethylenediaminetetraacetic acid (EDTA), hydroxyethylethylenediaminetriadetic acid (HEDTA), other complexants, and lesser quantities of ion exchange polymers and minor organic compounds. A study of how thermal and radiological processes that may have changed the composition of organic tanks constituents has been initiated after a review of the open literature revealed little information was available about the rates and products of these processes under basic pH conditions. This paper will detail the initial findings as they relate to gas generation, e.g. H{sub 2}, CO, NH{sub 3}, CH{sub 4}, and to changes in the composition of the organic and inorganic components brought about by ``Aging`` processes.

  3. Nongenetic Determinants of Age at Menarche: A Systematic Review

    PubMed Central

    2014-01-01

    Background. The acceleration of pubertal development is an important medical and social problem, as it may result in increased morbidity and mortality in later life. This systematic review summarizes relevant data about nongenetic factors, which contribute to age at menarche (AAM), and suggests those which may be the most important. Methods. The available literature from 1980 till July 2013 was searched using PubMed and Google Scholar databases. Finally, 154 papers were selected for the analysis. Results. Environmental factors, which may affect AAM, vary in populations of different ethnicity. The prenatal, infancy, and early childhood periods are the most susceptible to these factors. Body weight, high animal protein intake, family stressors (e.g., single parenting), and physical activity seem to influence AAM in most populations. Conclusions. The data about influence of nongenetic factors on AAM are still inconsistent. The factors affecting prenatal and early childhood growth seem to have a larger effect on further sexual maturation. Further studies are needed in order to validate the association between other environmental determinants and AAM in different ethnical groups. PMID:25050345

  4. Older adults' evaluations of middle-aged children's attempts to initiate discussion of care needs.

    2014-01-01

    We explored how older adults evaluated the strategies used by an adult child to initiate discussion of future care needs, and subsequently, whether these judgments affected older adults' willingness to engage in discussions about eldercare if approached in a similar fashion by one of their own children. One hundred and thirty older adults were randomly assigned to read one of four scripts depicting efforts by a middle-aged daughter to raise the topic of future care needs with her mother by implementing a variety of facework behaviors. Scripts manipulated the degree to which the daughter conveyed respect for her mother's desires for autonomy (negative face) and connection (positive face). The daughter's facework significantly predicted older parents' evaluation of her as supportive, which in turn predicted their willingness to discuss future care needs with one of their own children if they were to approach the conversation in a similar way.

    Elevated Depressive symptoms (DS) are associated with incident mild cognitive impairment and probable dementia in postmenopausal women. We examined the association of elevated DS with domain-specific cognitive changes, and the moderating role of cardiovascular risk factor (CVRF) severity and cardiovascular disease (CVD). 2221 elderly women who participated in the Women's Health Initiative Study of Cognitive Aging were separated into those with (N = 204) and without (N = 2017) elevated DS. DS and multi-domain cognitive outcomes were measured annually for an average follow-up of 5.04 years. Women with elevated DS showed baseline multi-domain cognitive deficits, but longitudinal declines in global cognition only. Persistent DS was related to greater global cognition, and verbal knowledge and fluency, and memory declines. Significant DS-CVD interactions were observed cross-sectionally (but not longitudinally) for figural memory and fine motor speed. Future studies should investigate the role of nonvascular mechanisms linking DS and cognitive decline. PMID:24584465

    Aging is initiated based on genetic and environmental factors that operate from the time of birth of organisms. Aging induces physiological phenomena such as reduction of cell counts, deterioration of tissue proteins, tissue atrophy, a decrease of the metabolic rate, reduction of body fluids, and calcium metabolism abnormalities, with final progression onto pathological aging. Despite the efforts from many researchers, the progression and the mechanisms of aging are not clearly understood yet. Therefore, the authors would like to introduce several theories which have gained attentions among the published theories up to date; genetic program theory, wear-and-tear theory, telomere theory, endocrine theory, DNA damage hypothesis, error catastrophe theory, the rate of living theory, mitochondrial theory, and free radical theory. Although there have been many studies that have tried to prevent aging and prolong life, here we introduce a couple of theories which have been proven more or less; food, exercise, and diet restriction.

  8. OH-Radical initiated ageing of biogenic secondary organic aerosols - A detailed chemical analysis

    The chemical ageing[1] of secondary organic aerosol (SOA) was investigated in two series of experiments using on-line mass spectrometry and off-line high performance liquid chromatography mass spectrometry (HPLC-MS). In a set of photochemical experiments, performed in the large outdoor reaction chamber SAPHIR (Jülich, Germany), SOA was generated from a boreal mixture including mono- and sesquiterpenes (α-pinene, β-pinene, Δ3-carene, limonene, caryophyllene). During a long time experiment (30h) the generated SOA was exposed to OH-radicals and the chemical composition was analyzed on-line using atmospheric pressure ionization mass spectrometry (API-MS). The on-line method provides highly time resolved chemical information and therefore a direct insight into the temporal changes of SOA-composition. In parallel, filter samples analysed by HPLC-MS allow the enrichment of trace compounds and finally an unambiguous identification of individual substances. In addition, filter samples allow a direct comparison to samples from field studies. The ageing experiments showed a clear change in SOA composition. The compounds observed can be divided into two groups: A group of first generation SOA-compounds, generated by the OH oxidation of the terpenes and a group of second generation compounds, generated by the reaction of OH with SOA compounds. Among the second generation products, especially a tricarboxylic acid (3-methyl-1,2,3-butanetricarboxylic acid, m/z 203)[2] was observed to be a good marker compound for BSOA ageing. A further set of experiments was carried out in another large aerosol chamber facility, the AIDA chamber of the Research Centre Karlsruhe. In this dark chamber, the experiments focused on the OH-induced ageing of α-pinene SOA and the influence of temperature. The results clearly show that the tricarboxylic acid is a distinctive marker for OH radical induced BSOA ageing and identify cis-pinonic acid as its precursor. To connect the results of the

    A growing number of older adults coupled with a limited number of physicians trained in geriatrics presents a major challenge to ensuring quality medical care for this population. Innovations to incorporate geriatrics education into internal medicine residency programs are needed. To meet this need, in 2009, faculty at the Medical University of South Carolina developed Aging Q(3)-Quality Education, Quality Care, and Quality of Life. This multicomponent initiative recognizes the need for improved geriatrics educational tools and faculty development as well as systems changes to improve the knowledge and clinical performance of residents. To achieve these goals, faculty employ multiple intervention strategies, including lectures, rounds, academic detailing, visual cues, and electronic medical record prompts and decision support. The authors present examples from specific projects, based on care areas including vision screening, fall prevention, and caring for patients with dementia, all of which are based on the Assessing Care of Vulnerable Elders quality indicators. The authors describe the principles driving the design, implementation, and evaluation of the Aging Q(3) program. They present data from multiple sources that illustrate the effectiveness of the interventions to meet the knowledge, skill level, and behavior goals. The authors also address major challenges, including the maintenance of the teaching and modeling interventions over time within the context of demanding primary care and inpatient settings. This organized, evidence-based approach to quality improvement in resident education, as well as faculty leadership development, holds promise for successfully incorporating geriatrics education into internal medicine residencies.

  10. The aetiology and trajectory of anabolic-androgenic steroid use initiation: a systematic review and synthesis of qualitative research

    PubMed Central

    2014-01-01

    Background To our knowledge, there has never been a systematic review and synthesis of the qualitative literature on the trajectory and aetiology of nonmedical anabolic-androgenic steroid (AAS) use. Methods We systematically reviewed and synthesized qualitative literature gathered from searches in PsycINFO, PubMed, ISI Web of Science, Google Scholar, and reference lists of relevant literature to investigate AAS users’ ages of first use and source(s), history prior to use, and motives/drives for initiating use. We adhered to the recommendations of the UK Economic and Social Research Council’s qualitative research synthesis manual and the PRISMA guidelines. Results A total of 44 studies published between 1980 and 2014 were included in the synthesis. Studies originated from 11 countries: the United States (n = 18), England (n = 8), Australia (n = 4), Sweden (n = 4), both England and Wales (n = 2), and Scotland (n = 2). One study each originated from Brazil, Bulgaria, Canada, France, Great Britain, and Norway. The majority of AAS users initiated use before age 30. Sports participation (particularly power sports), negative body image, and psychological disorders such as depression preceded initiation of AAS use for most users. Sources of first AAS were mainly users’ immediate social networks and the illicit market. Enhanced sports performance, appearance, and muscle/strength were the paramount motives for AAS use initiation. Conclusions Our findings elucidate the significance of psychosocial factors in AAS use initiation. The proliferation of AAS on the illicit market and social networks demands better ways of dealing with the global public health problem of AAS use. PMID:24984881

    Transactive response DNA-binding protein of 43 kDa (TDP-43), an RNA and DNA binding protein involved in transcriptional repression, RNA splicing and RNA metabolism during the stress response, is the major component of neuronal inclusions in amyotrophic lateral sclerosis (ALS) and frontotemporal lobar degeneration with ubiquitin inclusions, now referred to as FTLD-TDP. While initially thought to be relatively specific to ALS and FTLD-TDP, TDP-43 pathology has now been detected in a number of other neurodegenerative diseases, many associated with tau pathology, including Guam Parkinson dementia complex and Alzheimer's disease (AD). TDP-43 pathology is detected in 25% to 50% of AD cases, especially those with more severe clinical phenotype and greater Alzheimer type pathology, as well as AD cases with hippocampal sclerosis (HS). HS is characterized by selective neuronal loss affecting CA1 sector of the hippocampus, and most cases of HS, with or without AD, have TDP-43 pathology. Whether TDP-43 pathology is merely an incidental finding in AD or actually contributing to the more severe clinical phenotype remains unresolved. Presence of TDP-43 in normal elderly, who are at increased risk for AD, would strengthen the argument that it is not merely a secondary or incidental finding in end stage AD. Limited studies suggest that TDP-43 pathology is infrequent in neurologically normal elderly (3% or less). We provide an overview of what is known about TDP-43 in AD, normal aging and in other disorders and suggest that TDP-43 proteinopathies be considered in two classes - primary and secondary.

  14. Past and future ice age initiation: the role of an intrinsic deep-ocean millennial oscillation

    2014-05-01

    This paper offers three interdependent contributions to studies of climate variation: (1) the recognition and analysis of an intrinsic millennial oceanic oscillation that affects both Northern and Southern high latitude climates, (2) The recognition of an oceanographic switch to ice-free seas west of Greenland that explains the initiation of the Last Ice Age, and (3) an analysis of the effect of increasing salinity in the seas east of Greenland that suggests the possibility of the initiation of an ice age threshold climate in the near future. In the first contribution the millennial oscillation in the flow of the North Atlantic Drift reported by Bond et al. (1997) is proposed to be part of a 1500 yr intrinsic deep ocean oscillation. This oscillation involves the exchange of North Atlantic intermediate-level deep water (NADW) formed in the seas east of Greenland with Antarctic Bottom Water formed in a shallow-water zone at the edge of the Antarctic continent. The concept of NADW formation is already well known, with details of the sinking water flowing out of the Greenland Sea observed by Smethie et al. (2000) using chlorofluorocarbon tracers. The concept of Antarctic Bottom Water formation is also already well established. However, its modulation by the changing fraction of NADW in the Southern Ocean, which I infer from the analysis of Weyl (1968), has not been previously discussed. The modulated lower-salinity Antarctic Bottom Water that reaches the northern North Atlantic then provides negative feedback for the cyclic variation of NADW formation as proposed here. This causes the 1500 yr bipolar oscillation. The feedback suggests the possible sinusoidal character of the proposed oscillation model. The model is consistent with the cooling of the Little Ice Age (Lamb, 1972, 1995), and it also correctly predicts NASA's observation of today's record maximum area of winter sea ice on the Southern Ocean and the present observed record low rate of Antarctic Bottom Water

    Initiating event is defined as any event either internal or external to the nuclear power plants (NPPs) that perturbs the steady state operation of the plant, if operating, thereby initiating an abnormal event such as transient or loss of coolant accident (LOCA) within the NPPs. These initiating events trigger sequences of events that challenge plant control and safety systems whose failure could potentially lead to core damage or large early release. Selection for initiating events consists of two steps i.e. first step, definition of possible events, such as by evaluating a comprehensive engineering, and by constructing a top level logic model. Then the second step, grouping of identified initiating event's by the safety function to be performed or combinations of systems responses. Therefore, the purpose of this paper is to discuss initiating events identification in event tree development process and to reviews other probabilistic safety assessments (PSA). The identification of initiating events also involves the past operating experience, review of other PSA, failure mode and effect analysis (FMEA), feedback from system modeling, and master logic diagram (special type of fault tree). By using the method of study for the condition of the traditional US PSA categorization in detail, could be obtained the important initiating events that are categorized into LOCA, transients and external events.

    The complex pyroxene exsolution texture of the Moore County cumulate eucrite was interpreted by Miyamoto and Takeda as indicating initial cooling at 160 C/Ma followed by a sudden temperature rise and final cooling at 0.35 C/yr. They suggested initial cooling at a depth of approx. 8 km near the base of Vesta s crust, followed by impact excavation to its surface. Young Sm-Nd ages of approx. 4456, 4460, and 4410 Ma, respectively, for the Moore County, Moama, and Serra de Mag cumulate eucrites are puzzling because closure to Nd isotopic exchange would occur in only a few Ma at the above initial cooling rate. The exception to young ages among the cumulate eucrites is EET87520, with a 147Sm-147 - Nd-143 age of 4547-4598 Ma. We report here initial results of a combined mineralogical/chronological study of the Yamato 980318 feldspar-cumulate eucrite.

    Background & objectives: Tobacco use among school children is becoming a serious problem in developing countries. The early age of initiation underscores the urgent need to intervene and protect this vulnerable group from falling prey to this addiction. The present study was thus undertaken to assess the prevalence of tobacco habits among school children, determine the age of initiation of these habits, and compare the age of initiation between students who were more than 15 and ≤ 15 yr of age. Methods: Data on tobacco use were collected from 4786 students of class 7 to 12 (age: 11-19 yr) studying in different private and government schools of Noida city during July- December 2005, through cluster and random sampling using a self-administered questionnaire. Results: Any kind of tobacco use was found in 537 (11.2%) students; 419 (8.8%) were ‘ever smokers (including current smokers)’ 219 (4.6%) were ‘ever tobacco chewers (including current chewers)’, 179 (3.7%) were ‘exclusive smokers’ and 118 (2.5%) were ‘exclusive tobacco chewers’. The mean age of initiation of these habits was around 12.4 yr. More than 50 per cent of tobacco chewers reported use of khaini at least once. Nearly 70 per cent of boys and 80 per cent of girls ≤ 15 yr initiated the habit of tobacco before the age of 11 yr. A significant early uptake of tobacco chewing was reported from private school students as compared to government school students (P<0.05). Interpretation & conclusions: Tobacco addiction is emerging as a big threat among children. Our findings indicate a recent downward shift in the age at initiation of tobacco uptake and rising prevalence among girls. Such data need to be collected from different parts of the country to develop anti-tobacco campaigns and take policy decision. PMID:21441684

  19. Initiation age and incision rates of inner gorges: Do they record multiple glacial-interglacial cycles?

    Inner gorges represent some of the most conspicuous landforms in the European Alps. They form narrow and deep active-channel incisions that link hanging tributaries with trunk valleys in glacially-conditioned environments. Despite abundant research carried out on these objects, both their origin and evolution have remained unclear. In particular, the age of initiation, the rate of incision, and the respective contribution of fluvial and subglacial processes in the evolution of inner gorges have still been a matter of scientific debate. Indeed, answering these questions has been complicated by the lack of appropriate quantitative methods and/or suitable sampling strategies for studying inner gorges. Here, we report 10Be concentrations measured in alluvial sediments that have been collected along the main stream of a ~20-km2-catchment in the Swiss foreland (Central European Alps). This catchment hosts a ca. 100-m-deep and 2-km-long inner gorge that has been cut mainly in glacial till. Catchment wide denudation rates inferred from 10Be analyses (n = 15) vary from ~120 to 650 mm/ka and show a general downstream increasing trend. Additional field observations and GIS analyses reveal that the denudation rates within the catchment increase from the headwaters, characterized by relict glacial/periglacial landscapes, to the downstream end of the basin where the inner gorge has been formed. Using a 10Be-based sediment budget approach and the delineation of topographic domains from a 2-m-resolution LIDAR, we provide an estimate of erosion rates within the gorge that are higher than 2.5 m/ka and can reach up to ~ 7 m/ka. Combining these estimated erosion rates with the reconstruction of eroded volumes within the gorge, we obtain a rough initiation age in the early Holocene, in general agreement with previous studies reporting a postglacial origin for the inner gorges. Our results therefore appear contradictory with recent findings arguing for a gradual formation of inner

    We study numerically the two-dimensional Ising model with nonconserved dynamics quenched from an initial equilibrium state at the temperature Ti≥Tc to a final temperature Tf below the critical one. By considering processes initiating both from a disordered state at infinite temperature Ti=∞ and from the critical configurations at Ti=Tc and spanning the range of final temperatures Tf∈[0 ,Tc[ we elucidate the role played by Ti and Tf on the aging properties and, in particular, on the behavior of the autocorrelation C and of the integrated response function χ . Our results show that for any choice of Tf, while the autocorrelation function exponent λC takes a markedly different value for Ti=∞ [λC(Ti=∞ ) ≃5 /4 ] or Ti=Tc [λC(Ti=Tc) ≃1 /8 ] the response function exponents are unchanged. Supported by the outcome of the analytical solution of the solvable spherical model we interpret this fact as due to the different contributions provided to autocorrelation and response by the large-scale properties of the system. As changing Tf is considered, although this is expected to play no role in the large-scale and long-time properties of the system, we show important effects on the quantitative behavior of χ . In particular, data for quenches to Tf=0 are consistent with a value of the response function exponent λχ=1/2 λC(Ti=∞ ) =5 /8 different from the one [λχ∈(0.5 -0.56 ) ] found in a wealth of previous numerical determinations in quenches to finite final temperatures. This is interpreted as due to important preasymptotic corrections associated to Tf>0 .

    Objective Animal studies report that age at stimulant exposure is positively related to later drug sensitivity. This study was designed to examine whether age at initiation of stimulant treatment in children with attention deficit hyperactivity disorder (ADHD) is related to subsequent development of substance use disorder (SUD). Method Prospective longitudinal study of 176 methylphenidate-treated white boys (6–12 years) with ADHD but without conduct disorder, evaluated at mean ages 18 (94% retention) and 25 (85%), and 178 comparisons diagnosed by blinded clinicians. The Cox proportional hazards model included childhood predictor variables: age at initiation of methylphenidate treatment, total cumulative dose, treatment duration; IQ; severity of hyperactivity; socioeconomic status; also lifetime parent mental disorder. Separate models tested for four lifetime outcomes: Any SUD, Alcohol SUD, Non-Alcohol SUD, and Stimulant SUD. Other outcomes included antisocial personality disorder, mood and anxiety disorders. Results There was a significant positive relationship between age at treatment initiation and Non-Alcohol SUD. None of the predictors accounted for this association. Post-hoc analyses showed that the development of antisocial personality disorder explained the relationship between age at first methylphenidate treatment and later SUD. Even when controlling for SUD, age at stimulant treatment initiation was significantly and positively related to the later development of antisocial personality disorder. Age at first methylphenidate treatment was unrelated to mood and anxiety disorders. Conclusion Early age at initiation of methylphenidate treatment of children with ADHD does not increase risk for negative outcomes, and may have beneficial long-term effects. PMID:18381904

    This report presents the results of a recent research project originally concerned with review of governmental initiatives for changes to hospital design and operation standards at both the federal and state levels. However. it quickly became apparent that concern with energy conservation was not impacting hospital environmental standards, especially at the state level, irrespective of the energy implications. Consequently, the study was redirected to consider all energy conservation initiatives directed toward design and operating practices unique to the hospital environment. The scope was limited to agency programs (i.e., not undertaken at the initiative of individual hospitals), applicable to non-federal public and private hospitals.

    A number of health and lifestyle factors are thought to contribute to cognitive decline associated with age but cannot be easily modified by the individual patient. We identified 12 individually modifiable interventions that can be implemented during midlife or later with the potential to ameliorate cognitive aging. For ten of these, we used PubMed databases for a systematic review of long-duration (at least 6 months), randomized, controlled trials in midlife and older adults without dementia or mild cognitive impairment with objective measures of neuropsychological performance. Using network meta-analysis, we performed a quantitative synthesis for global cognition (primary outcome) and episodic memory (secondary outcome). Of 1038 publications identified by our search strategy, 24 eligible trials were included in the network meta-analysis. Results suggested that the Mediterranean diet supplemented by olive oil and tai chi exercise may improve global cognition, and the Mediterranean diet plus olive oil and soy isoflavone supplements may improve memory. Effect sizes were no more than small (standardized mean differences 0.11-0.22). Cognitive training may have cognitive benefit as well. Most individually modifiable risk factors have not yet been adequately studied. We conclude that some interventions that can be self-initiated by healthy midlife and older adults may ameliorate cognitive aging. PMID:26361790

    Children (405), initially of average age 11.5 years, recorded all food and drinks consumed for three consecutive days (with an interview on the fourth day) on five separate occasions over a 2-year period. Food tables (Paul & Southgate, 1978) enabled nutrient intakes to be calculated. The data collected were found to be of high reliability (Hackett et al. 1983). The mean energy intakes showed broad agreement with other recent British dietary surveys but were well below those recorded in the prewar study by Widdowson (1947) and the FAO/WHO (1973) recommended levels. They were slightly below the current Department of Health and Social Security (DHSS; 1979) recommended intakes. Over the 2-year period, the energy intake of the boys increased by 13% compared with an increase of only 7% in the girls. The iron and vitamin A intakes of all groups of children were low compared with current recommendations (DHSS, 1979). This seems to be a result of falling energy intake. Mean calcium intakes were also only marginally in excess of the recommended intake, and those of most of the girls would fall below the recommendation if the proposal to end the fortification of flour (DHSS, 1981) is implemented.

    Ray-finned fishes (Actinopterygii) comprise nearly half of all modern vertebrate diversity, and are an ecologically and numerically dominant megafauna in most aquatic environments. Crown teleost fishes diversified relatively recently, during the Late Cretaceous and early Paleogene, although the exact timing and cause of their radiation and rise to ecological dominance is poorly constrained. Here we use microfossil teeth and shark dermal scales (ichthyoliths) preserved in deep-sea sediments to study the changes in the pelagic fish community in the latest Cretaceous and early Paleogene. We find that the Cretaceous−Paleogene (K/Pg) extinction event marked a profound change in the structure of ichthyolith communities around the globe: Whereas shark denticles outnumber ray-finned fish teeth in Cretaceous deep-sea sediments around the world, there is a dramatic increase in the proportion of ray-finned fish teeth to shark denticles in the Paleocene. There is also an increase in size and numerical abundance of ray-finned fish teeth at the boundary. These changes are sustained through at least the first 24 million years of the Cenozoic. This new fish community structure began at the K/Pg mass extinction, suggesting the extinction event played an important role in initiating the modern “age of fishes.” PMID:26124114

    SUMMARY Age-related neurodegenerative diseases are associated with mild impairment of oxidative metabolism and accumulation of abnormal proteins. Within the cell, the mitochondria appears to be a dominant site for initiation and propagation of disease processes. Shifts in metabolism in response to mild metabolic perturbations may decrease the threshold for irreversible injury in response to ordinarily sub lethal metabolic insults. Mild impairment of metabolism accrue from and lead to increased reactive oxygen species (ROS). Increased ROS change cell signaling via post transcriptional and transcriptional changes. The cause and consequences of mild impairment of mitochondrial metabolism is one focus of this review. Many experiments in tissues from humans support the notion that oxidative modification of the α-ketoglutarate dehydrogenase complex (KGDHC) compromises neuronal energy metabolism and enhance ROS production in Alzheimer’s Disease (AD). These data suggest that cognitive decline in AD derives from the selective tricarboxylic acid (TCA) cycle abnormalities. By contrast in Huntington’s Disease (HD), a movement disorder with cognitive features distinct form AD, complex II + III abnormalities may dominate. These distinct mitochondrial abnormalities culminate in oxidative stress, energy dysfunction, and aberrant homeostasis of cytosolic calcium. Cytosolic calcium, elevations even only transiently, leads to hyperactivity of a number of enzymes. One calcium activated enzyme with demonstrated pathophysiological import in HD and AD is transglutaminase (TGase). TGase is a cross linking enzymes that can modulate transcrption, inactivate metabolic enzymes, and cause aggregation of critical proteins. Recent data indicate that TGase can silence expression of genes involved in compensating for metabolic stress. Altogether, our results suggest that increasing KGDHC via inhibition of TGase or via a host of other strategies to be described would be effective therapeutic

  10. Mechanisms of the anorexia of aging-a review.

    Many, even healthy, older people fail to adequately regulate food intake and experience loss of weight. Aging-associated changes in the regulation of appetite and the lack of hunger have been termed as the anorexia of aging. The etiology of the anorexia of aging is multi-factorial and includes a combination of physiological changes associated with aging (decline in smell and taste, reduced central and peripheral drive to eat, delayed gastric emptying), pathological conditions (depression, dementia, somatic diseases, medications and iatrogenic interventions, oral-health status), and social factors (poverty, loneliness). However, exact mechanisms of the anorexia of aging remain to be elucidated. Many neurobiological mechanisms may be secondary to age-related changes in body composition and not associated with anorexia per se. Therefore, further studies on pathophysiological mechanisms of the anorexia of aging should employ accurate measurement of body fat and lean mass. The anorexia of aging is associated with protein-energy malnutrition, sarcopenia, frailty, functional deterioration, morbidity, and mortality. Since this symptom can lead to dramatic consequences, early identification and effective interventions are needed. One of the most important goals in the geriatric care is to optimize nutritional status of the elderly. PMID:26232135

    2016-01-01

    Openness is one of the central values of science. Open scientific practices such as sharing data, materials and analysis scripts alongside published articles have many benefits, including easier replication and extension studies, increased availability of data for theory-building and meta-analysis, and increased possibility of review and collaboration even after a paper has been published. Although modern information technology makes sharing easier than ever before, uptake of open practices had been slow. We suggest this might be in part due to a social dilemma arising from misaligned incentives and propose a specific, concrete mechanism—reviewers withholding comprehensive review—to achieve the goal of creating the expectation of open practices as a matter of scientific principle.

    2013-01-01

    Background Prostate cancer (pca) is the most common non-skin cancer among men in Canada and other Western countries. Increased prevalence and higher cost of newer treatments have led to a significant rise in the economic burden of pca. The objectives of the present study were to systematically review the literature on direct costs for the initial management of pca, and to examine the methodologic considerations across studies. Methods Bibliographic databases were systematically searched for peer-reviewed articles in English. Studies were reviewed for methodologic considerations and mean direct cost of active surveillance or watchful waiting (as/ww) and initial treatments. Direct cost was standardized to 2011 Canadian dollars. Results After a review of abstracts and full-text papers, seventeen articles met the eligibility criteria and were included in the review. Studies were published during 1992–2010. The studies reported on health care systems in the United States, France, the United Kingdom, German, Italy, and Spain. Our review identified a lack of methodologic consensus, leading to variation in direct costs between studies. Nevertheless, results indicate a significant direct cost of pca treatments. Conclusions The existing literature lacks methodologically rigorous studies on the direct costs of pca treatments specific to publicly funded health care systems. Additional studies are required to appreciate the direct costs of newer treatments and the impact of their adoption on the growing economic burden of pca management. PMID:24311952

    Summary The ability to assess bone age accurately is important and allows to diagnose the patient correctly and to plan orthodontic treatment appropriately. The aim of the work is to present views of different authors on the subject of using cephalometric images to determine bone age and its significance for conducting appropriate orthodontic treatment. Publications from the PubMed medical database were analyzed. Search criteria: bone age assessment, CVM method. Ultimately, 36 papers out of 1354 publications were selected. The research of many authors confirms the usefulness of various methods using cephalometric images to assess skeletal age. Currently, the CVM method devised by Baccetti et al. is the most frequently mentioned one in literature. It seems that bone age assessment methods based on evaluating the morphological structure of the cervical vertebrae in cephalometric images can clearly differentiate skeletal maturity in children regardless of their race or sex. Bearing in mind the constant technological progress in medicine and stomatology, bone age assessment methods need to be perfected in order to alleviate their impact on the patient as much as possible.

    2008-01-01

    Background Early detection of cognitive decline in the elderly has become of heightened importance in parallel with the recent advances in therapeutics. Computerized assessment may be uniquely suited to early detection of changes in cognition in the elderly. We present here a systematic review of the status of computer-based cognitive testing focusing on detection of cognitive decline in the aging population. Methods All studies purporting to assess or detect age-related changes in cognition or early dementia/mild cognitive impairment (MCI) by means of computerized testing were included. Each test battery was rated on availability of normative data, level of evidence for test validity and reliability, comprehensiveness, and usability. All published studies relevant to a particular computerized test were read by a minimum of two reviewers, who completed rating forms containing the above-mentioned criteria. Results Of the 18 test batteries identified from the initial search, eleven were appropriate to cognitive testing in the elderly and were subjected to systematic review. Of those 11, five were either developed specifically for application with the elderly or have been used extensively with that population. Even within the computerized testing genre, great variability existed in manner of administration, ranging from fully examiner administered to fully self-administered. All tests had at least minimal reliability and validity data, commonly reported in peer-reviewed articles. However, level of rigor of validity testing varied widely. Conclusion All test batteries exhibited some of the strengths of computerized cognitive testing: standardization of administration and stimulus presentation, accurate measures of response latencies, automated comparison in real-time with an individual’s prior performance as well as with age-related norms, and efficiencies of staffing and cost. Some, such as the MCIS, adapted complicated scoring algorithms to enhance the information

  1. Aging and potential for self-renewal: hydra living in the age of aging - a mini-review.

    2014-01-01

    Hydra present an interesting deviation from typical life histories: they have an extensive capacity to regenerate and self-renew and seem to defy the aging process. Hydra have the ability to decouple the aging process from their life history and therefore provide us with a unique opportunity to gain insight into the aging process not only for basal hydrozoans but also for other species across the tree of life. We argue that under steady feeding and asexual reproduction Hydra species are able to escape aging as a result of high levels of cell proliferation and regenerative ability. We further highlight cellular processes for stem cell maintenance, such as the telomere dynamic, which prevent the accumulation of damage and protect against diseases and pathogens that mediate this condition. In addition, we discuss the causes of aging in other Hydra species. PMID:25012456

    Compared to men, women live longer but experience greater morbidity as they age. However, little is known about the rapidly growing population of women aging with disability. Women aging with disabilities may encounter barriers that increase risk of morbidity, including lack of access to medical care or inadequate assistance, equipment, or services. To evaluate risks of morbidity in this group, we conducted a systematic review focused on two important and prevalent conditions: cardiovascular disease (CVD) and osteoporosis. MEDLINE was searched for reports published between January 1, 1990 and August 6, 2010 and additional studies were identified through searches of bibliographies. 9,156 abstracts and 93 articles were reviewed to identify empirical studies of women with physical disability who were 45 years or older and that reported CVD or osteoporosis as an outcome and not a cause of the disability. Articles meeting inclusion criteria were then critically appraised to exclude poor quality studies. In seven articles that evaluated CVD outcomes, we found limited evidence to support an increased risk of prevalence of CVD or risk factors for CVD in women aging with physical disabilities compared to non-disabled control populations. The literature is limited by small sample sizes that reduced statistical power to detect true differences. No articles meeting inclusion criteria were identified to evaluate osteoporosis risk in this group. This review is limited by the narrow focus on physical disabilities and two health outcomes. Additional high quality empirical research is necessary to understand the risks to health of women aging with disabilities. PMID:21075569

    Maintaining a healthy brain is a critical factor for the quality of life of elderly individuals and the preservation of their independence. Challenging aging brains through cognitive training and physical exercises has shown to be effective against age-related cognitive decline and disease. But how effective are such training interventions? What is the optimal combination/strategy? Is there enough evidence from neuropsychological observations, animal studies, as well as, structural and functional neuroimaging investigations to interpret the underlying neurobiological mechanisms responsible for the observed neuroplasticity of the aging brain? This piece of work summarizes recent findings toward these questions, but also highlights the role of functional brain connectivity work, an emerging discipline for future research in healthy aging and the study of the underlying mechanisms across the life span. The ultimate aim is to conclude on recommended multimodal training, in light of contemporary trends in the design of exergaming interventions. The latter issue is discussed in conjunction with building up neuroscientific knowledge and envisaged future research challenges in mapping, understanding and training the aging brain. PMID:24705268

    2014-01-01

    GenPhilly is an innovative, replicable model that was developed in Philadelphia, Pennsylvania, to inspire and engage emerging leaders from a variety of disciplines to promote and sustain an aging-in-community agenda. Administrative support is provided by the Area Agency on Aging, Philadelphia Corporation for Aging, yet it was designed by its members to be peer-led. In this way, young professionals in their 20s and 30s can capitalize on popular culture to create unique professional development opportunities and get younger generations thinking about the type of city in which they themselves want to get older. The group has benefited the field of aging by building awareness of aging services in the wider community; facilitating cross-disciplinary learning and innovation around aging issues; stressing the competitive advantage for emerging leaders from all fields to know about aging issues; strengthening the aging network workforce; breaking down stereotypes about working with older adults; and introducing expertise from outside the aging network to benefit older adults. Encouraging the development of similar groups will not only benefit the field of aging, it will assist the next generation of leaders in many fields to plan better for their communities and for themselves.

    The Alzheimer’s Disease Neuroimaging Initiative (ADNI) is an ongoing, longitudinal, multicenter study designed to develop clinical, imaging, genetic and biochemical biomarkers for the early detection and tracking of Alzheimer’s disease (AD). The study aimed to enroll 400 subjects with early mild cognitive impairment (MCI), 200 subjects with early AD and 200 normal controls and $67 million funding was provided by both the public and private sectors including the National Institutes on Aging, thirteen pharmaceutical companies and two Foundations that provided support through the Foundation for NIH (FNIH). This article reviews all papers published since the inception of the initiative and summarizes the results as of February, 2011. The major accomplishments of ADNI have been 1) the development of standardized methods for clinical, magnetic resonance imaging (MRI) and positron emission tomography (PET) and cerebrospinal fluid (CSF) biomarkers in a multi-center setting; 2) elucidation of the patterns and rates of change of imaging and CSF biomarker measurements in control, MCI and AD patients. CSF biomarkers are consistent with disease trajectories predicted by β amyloid (Aβ) cascade [1] and tau mediated neurodegeneration hypotheses for AD while brain atrophy and hypometabolism levels show predicted patterns but exhibit differing rates of change depending on region and disease severity; 3) the assessment of alternative methods of diagnostic categorization. Currently, the best classifiers combine optimum features from multiple modalities including MRI, FDG-PET, CSF biomarkers and clinical tests; 4) the development of methods for the early detection of AD. CSF biomarkers, Aβ42 and tau as well as amyloid PET may reflect the earliest steps in AD pathology in mildly or even non-symptomatic subjects and are leading candidates for the detection of AD in its preclinical stages; 5) the improvement of clinical trial efficiency through the identification of subjects most

  11. Gender, ageing & carework in East and Southern Africa: A review

    PubMed Central

    Seeley, Janet

    2016-01-01

    An estimated 58 million persons aged 60-plus live in sub-Saharan Africa; by 2050 that number will rise sharply to 215 million. Older Africans traditionally get care in their old age from the middle generation. But in East and Southern Africa, HIV has hollowed out that generation, leaving many older persons to provide care for their children’s children without someone to care for him or herself in old age. Simultaneously, the burden of disease among older persons is changing in this region. The result is a growing care deficit. This article examines the existing literature on care for and by older persons in this region, highlighting understudied aspects of older persons’ experiences of ageing and care – including the positive impacts of carework, variation in the region, and the role of resilience and pensions. We advance a conceptual framework of gendered identities – for both men and women – and intergenerational social exchange to help focus and understand the complex interdependent relationships around carework, which are paramount in addressing the needs of older persons in the current care deficit in this region, and the Global South more generally.

  13. Review of the recording and age of the Mono Lake Excursion

    NASA Astrophysics Data System (ADS)

    2009-04-01

    Among the brief departures from gradual, long-term behaviour of the palaeomagnetic field in the Brunhes Normal Chron that reached opposite polarity or have a Virtual Geomagnetic Pole deep in the southern hemisphere, the first to be reported is the Laschamp Excursion (LE) in volcanic rocks in the Massif Central in France (Bonhommet and Zahringer, 1969). They originally believed it occurred between about 9,000 to 20,000 years before present, but it is now assigned an age of about 40,000 years B.P. (Guillou et al., 2004). Denham and Cox (1971) unsuccessfully sought the LE in exposed lake sediments that seemed to span that interval in the Mono Basin in the western Great Basin of the U.S., but instead encountered anomalous field behaviour that is called the Mono Lake Excursion (MLE)(Liddicoat and Coe, 1979). As a tribute to Norbert Bonhommet, who assisted us in our initial field work in the Mono Basin and shared a long-standing interest in the LE and MLE, we will review the palaeomagnetic behaviour and age of the MLE in the Mono Basin and elsewhere, for which there are nearly 20 reports of its occurrence globally, and evaluate the recent suggestion that the excursion at Mono Lake and the LE are the same.

    2015-01-01

    This systematic review was undertaken to determine the extent to which adult subjects representing sex (female), race (nonwhite), and age (>50 years) categories are included in clinical studies of HIV curative interventions and thus, by extension, the potential for data to be analyzed that may shed light on the influence of such demographic variables on safety and/or efficacy. English-language publications retrieved from PubMed and from references of retrieved papers describing clinical studies of curative interventions were read and demographic, recruitment year, and intervention-type details were noted. Variables of interest included participation by sex, age, and race; changes in participation rates by recruitment year; and differences in participation by intervention type. Of 151 publications, 23% reported full demographic data of study enrollees, and only 6% reported conducting efficacy analyses by demographic variables. Included studies recruited participants from 1991 to 2011. No study conducted safety analyses by demographic variables. The representation of women, older people, and nonwhites did not reflect national or international burdens of HIV infection. Participation of demographic subgroups differed by intervention type and study location. Rates of participation of demographic groups of interest did not vary with time. Limited data suggest efficacy, particularly of early therapy initiation followed by treatment interruption, may vary by demographic variables, in this case sex. More data are needed to determine associations between demographic characteristics and safety/efficacy of curative interventions. Studies should be powered to conduct such analyses and cure-relevant measures should be standardized. PMID:25313793

    Abstract This systematic review was undertaken to determine the extent to which adult subjects representing sex (female), race (nonwhite), and age (>50 years) categories are included in clinical studies of HIV curative interventions and thus, by extension, the potential for data to be analyzed that may shed light on the influence of such demographic variables on safety and/or efficacy. English-language publications retrieved from PubMed and from references of retrieved papers describing clinical studies of curative interventions were read and demographic, recruitment year, and intervention-type details were noted. Variables of interest included participation by sex, age, and race; changes in participation rates by recruitment year; and differences in participation by intervention type. Of 151 publications, 23% reported full demographic data of study enrollees, and only 6% reported conducting efficacy analyses by demographic variables. Included studies recruited participants from 1991 to 2011. No study conducted safety analyses by demographic variables. The representation of women, older people, and nonwhites did not reflect national or international burdens of HIV infection. Participation of demographic subgroups differed by intervention type and study location. Rates of participation of demographic groups of interest did not vary with time. Limited data suggest efficacy, particularly of early therapy initiation followed by treatment interruption, may vary by demographic variables, in this case sex. More data are needed to determine associations between demographic characteristics and safety/efficacy of curative interventions. Studies should be powered to conduct such analyses and cure-relevant measures should be standardized. PMID:25313793

    The Adventist Health Study 2 is a large cohort that is well suited to the study of the relation of vegetarian dietary patterns to health and disease risk. Here we review initial published findings with regard to vegetarian diets and several health outcomes. Vegetarian dietary patterns were associated with lower body mass index, lower prevalence and incidence of diabetes mellitus, lower prevalence of the metabolic syndrome and its component factors, lower prevalence of hypertension, lower all-cause mortality, and in some instances, lower risk of cancer. Findings with regard to factors related to vegetarian diets and bone health are also reviewed. These initial results show important links between vegetarian dietary patterns and improved health.

    Large blackouts are typically caused by cascading failure propagating through a power system by means of a variety of processes. Because of the wide range of time scales, mulitple interacting processes, and the hugh number of possible interactions, the simulation and analysis of cascading blackouts is extremely complicated. This paper defines cascading failure for blackouts and gives an initial review of the current understanding, industrial tools, and the challenges and emerging methods of analysis and simulation.

    PubMed

    Jornitz, Maik W

    2015-01-01

    Aging facilities have become a concern in the pharmaceutical and biopharmaceutical manufacturing industry, so much that task forces are formed by trade organizations to address the topic. Too often, examples of aging or obsolete equipment, unit operations, processes, or entire facilities have been encountered. Major contributors to this outcome are the failure to invest in new equipment, disregarding appropriate maintenance activities, and neglecting the implementation of modern technologies. In some cases, a production process is insufficiently modified to manufacture a new product in an existing process that was used to produce a phased-out product. In other instances, manufacturers expanded the facility or processes to fulfill increasing demand and the scaling occurred in a non-uniform manner, which led to non-optimal results. Regulatory hurdles of post-approval changes in the process may thwart companies' efforts to implement new technologies. As an example, some changes have required 4 years to gain global approval. This paper will address cases of aging processes and facilities aside from modernizing options. PMID:26242790

    Clarifying the existing evidence base is crucial to improve the effectiveness of transfusion practice. The UK Systematic Review Initiative has been pursuing this objective primarily through writing systematic reviews on important topics in transfusion medicine. Here, we describe our progress for the past 5 years. We are the only research group that identifies transfusion medicine randomized controlled trials (RCTs) for the Cochrane Central Register of Controlled Trials, and to date, we have contributed 3002 RCT citations. The article considers future challenges including the need for wider involvement from the transfusion medicine community in the process of maintaining and updating systematic reviews and the identification and prioritization of topics for further clinical research including clinical trials. Collaboration between international and local research groups is important if these challenges are to be met. PMID:19320853

    Telomeres shorten with each cell division and telomere dysfunction is a recognized hallmark of aging. Tissue proliferation is expected to dictate the rate at which telomeres shorten. We set out to test whether proliferative tissues age faster than non-proliferative due to telomere shortening during zebrafish aging. We performed a prospective study linking telomere length to tissue pathology and disease. Contrary to expectations, we show that telomeres shorten to critical lengths only in specific tissues and independently of their proliferation rate. Short telomeres accumulate in the gut but not in other highly proliferative tissues such as the blood and gonads. Notably, the muscle, a low proliferative tissue, accumulates short telomeres and DNA damage at the same rate as the gut. Together, our work shows that telomere shortening and DNA damage in key tissues triggers not only local dysfunction but also anticipates the onset of age-associated diseases in other tissues, including cancer.

    1988-11-01

    Hamsters were mated repeatedly at 60, 180, 300 and 420 days of age or once during their lifetime at one of these ages. Copulatory stimulation was varied both for number of ejaculations (2 versus 14) and amount of vaginocervical stimulation (5 versus 50-60 intromissions). Two ejaculations provided sufficient spermatozoa to maximize litter size for all age and parity classes tested. Differences in fecundity depended on the amount of vaginocervical stimulation received. Higher levels of vaginocervical stimulation increased littering success at 300 and 420 days for nulliparous females and at 180, 300 and 420 days for multiparous females. Females which did not deliver litters did not show a cessation of oestrous cycles which characteristically follows the induction of a luteal phase. The decreased fecundity observed with increasing age or parity therefore resulted from a change in sensitivity to the stimulus conditions necessary to activate the neuroendocrine arc for establishment of pregnancy.

    Objective To use a computational approach to investigate the cellular and extracellular matrix changes that occur with age in the knee joints of mice. Methods Knee joints from an inbred C57/BL1/6 (ICRFa) mouse colony were harvested at 3–30 months of age. Sections were stained with H&E, Safranin-O, Picro-sirius red and antibodies to matrix metalloproteinase-13 (MMP-13), nitrotyrosine, LC-3B, Bcl-2, and cleaved type II collagen used for immunohistochemistry. Based on this and other data from the literature, a computer simulation model was built using the Systems Biology Markup Language using an iterative approach of data analysis and modelling. Individual parameters were subsequently altered to assess their effect on the model. Results A progressive loss of cartilage matrix occurred with age. Nitrotyrosine, MMP-13 and activin receptor-like kinase-1 (ALK1) staining in cartilage increased with age with a concomitant decrease in LC-3B and Bcl-2. Stochastic simulations from the computational model showed a good agreement with these data, once transforming growth factor-β signalling via ALK1/ALK5 receptors was included. Oxidative stress and the interleukin 1 pathway were identified as key factors in driving the cartilage breakdown associated with ageing. Conclusions A progressive loss of cartilage matrix and cellularity occurs with age. This is accompanied with increased levels of oxidative stress, apoptosis and MMP-13 and a decrease in chondrocyte autophagy. These changes explain the marked predisposition of joints to develop osteoarthritis with age. Computational modelling provides useful insights into the underlying mechanisms involved in age-related changes in musculoskeletal tissues. PMID:25475114

    2013-10-01

    Paradoxically, aging leads to both decreased regenerative capacity in the brain and an increased risk of tumorigenesis, particularly the most common adult-onset brain tumor, glioma. A shared factor contributing to both phenomena is thought to be age-related alterations in neural progenitor cells (NPCs), which function normally to produce new neurons and glia, but are also considered likely cells of origin for malignant glioma. Upon oncogenic transformation, cells acquire characteristics known as the hallmarks of cancer, including unlimited replication, altered responses to growth and anti-growth factors, increased capacity for angiogenesis, potential for invasion, genetic instability, apoptotic evasion, escape from immune surveillance, and an adaptive metabolic phenotype. The precise molecular pathogenesis and temporal acquisition of these malignant characteristics is largely a mystery. Recent studies characterizing NPCs during normal aging, however, have begun to elucidate mechanisms underlying the age-associated increase in their malignant potential. Aging cells are dependent upon multiple compensatory pathways to maintain cell cycle control, normal niche interactions, genetic stability, programmed cell death, and oxidative metabolism. A few multi-functional proteins act as 'critical nodes' in the coordination of these various cellular activities, although both intracellular signaling and elements within the brain environment are critical to maintaining a balance between senescence and tumorigenesis. Here, we provide an overview of recent progress in our understanding of how mechanisms underlying cellular aging inform on glioma pathogenesis and malignancy. PMID:23711239

    2014-01-01

    HIV infection is no longer characterized by high morbidity, rapid progression to AIDS, and death as when the infection was first identified. While anti-retroviral drugs have improved the outcome of AIDS patients, clinical research on the appropriate time to initiate therapy continues to evolve. Optimal therapy initiation would maximize the benefits of these drugs, while minimizing side effects and drug resistance. Recent 2013 WHO guidelines changed HIV therapy initiation from 350 cells/μL to 500 cells/μL. This systematic review provides an evidence-based comparison of starting treatment at >500 cells/μL with starting treatment at the range between 350 cells/μL and 500 cells/μL. An 11% increase in risk was detected from initiation therapy at the 350–500 cells/μL range (0.37 [0.26, 0.53]), when compared with starting treatment before 500 cells/μL (0.33 [0.22, 0.48]). Most individual study comparisons showed a benefit for starting treatment at 500 cells/μL in comparison with starting at the 350–500 cells/μL range with risks ranging from 19% to 300%, though a number of comparisons were not statistically significant. Overall, the study provides evidence based support for initiating anti retroviral therapy at cell counts >500 cells/μL wherever possible to prevent AIDS mortality and morbidity. PMID:24778646

    2013-01-01

    AIM: To review the initial presentation and demonstrate the importance of Takotsubo cardiomyopathy. METHODS: A PubMed search using the terms “Takotsubo cardiomyopathy (TC)” and “apical ballooning syndrome” yielded 211 publications. Only those that were relevant were fully reviewed. The gender, age, precipitating stressor, main complaint at presentation, electrocardiogram (ECG) at admission and serum cardiac markers of patients diagnosed with TC, were extracted as available. The data were organized in tables and graphics, and the incidence of the disorder was calculated and analyzed. RESULTS: A total of 250 clinical cases were examined. The predominant gender that was affected was female, with a prevalence of 87.5%. The mean age of presentation was 64 ± 14 years. The cases were divided by age into 10-year intervals. The age interval of 60-69 years showed the highest frequency of TC, accounting for 79 cases. The most common precipitating stressor was physical (50% of cases). Chest pain was the primary complaint at presentation (58.8% of cases) followed by dyspnea (30% of cases). The ST segment changes category was the most common (60%), followed by T wave changes (39.6%). Of the 60% of cases with ST segment changes, 12% had concomitant T wave changes. This means that for 27.6% of the cases, the primary abnormality in the ECG was T wave changes; 87.6% of cases with TC had a change in the ST segment, in the T wave or in both. The percentage of ECGs presenting with changes in the anterior wall was 54.4% (35.6% of ST segment elevation + 1.6% of ST segment depression + 17.2% of T wave inversion). The percentage of patients presenting with changes in the lateral segment of the heart was 46.8%, while the percentage of patients with changes in the inferior heart was 21.6% and the percentage of patients with changes in the apical region was only 16%. The prevalence of elevated creatinine kinase and/or troponin on initial presentation was 89.3%. CONCLUSION: It is

    2014-01-01

    Background The use of combination antiretroviral therapy (cART) comprising three antiretroviral medications from at least two classes of drugs is the current standard treatment for HIV infection in adults and children. Current World Health Organization (WHO) guidelines for antiretroviral therapy recommend early treatment regardless of immunologic thresholds or the clinical condition for all infants (less than one years of age) and children under the age of two years. For children aged two to five years current WHO guidelines recommend (based on low quality evidence) that clinical and immunological thresholds be used to identify those who need to start cART (advanced clinical stage or CD4 counts ≤ 750 cells/mm3 or per cent CD4 ≤ 25%). This Cochrane review will inform the current available evidence regarding the optimal time for treatment initiation in children aged two to five years with the goal of informing the revision of WHO 2013 recommendations on when to initiate cART in children. Objectives To assess the evidence for the optimal time to initiate cART in treatment-naive, HIV-infected children aged 2 to 5 years. Search methods We searched the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, EMBASE, the AEGIS conference database, specific relevant conferences, www.clinicaltrials.gov, the World Health Organization International Clinical Trials Registry platform and reference lists of articles. The date of the most recent search was 30 September 2012. Selection criteria Randomised controlled trials (RCTs) that compared immediate with deferred initiation of cART, and prospective cohort studies which followed children from enrolment to start of cART and on cART. Data collection and analysis Two review authors considered studies for inclusion in the review, assessed the risk of bias, and extracted data on the primary outcome of death from all causes and several secondary outcomes, including incidence of CDC category C and B clinical events and

    2015-09-01

    Global ageing demographics coupled with increased urbanisation pose major challenges to the provision of optimal living environments for older persons, particularly in relation to cognitive health. Although animal studies emphasize the benefits of enriched environments for cognition, and brain training interventions have shown that maintaining or improving cognitive vitality in older age is possible, our knowledge of the characteristics of our physical environment which are protective for cognitive ageing is lacking. The present review analyses different environmental characteristics (e.g. urban vs. rural settings, presence of green) in relation to cognitive performance in ageing. Studies of direct and indirect associations between physical environment and cognitive performance are reviewed in order to describe the evidence that our living contexts constitute a measurable factor in determining cognitive ageing.

    Accumulating evidence supports the notion that thyroid cancer is initiated by tumor-initiating cells (TICs) (commonly known as cancer stem cells), which are thought to play a crucial role in malignant progression, therapeutic resistance and recurrence. Thyroid TICs have been isolated and identified using specific biomarkers (such as CD133), the side population, sphere formation and aldehyde dehydrogenase activity assays. Although their characteristics remain largely unknown, TICs provide an attractive cellular mechanism to explain therapeutic refractoriness. Efforts are currently being directed toward the identification of therapeutic strategies that could target these cells. The present review discusses the cellular origins of TICs and the main approaches used to isolate and identify thyroid TICs, with a focus on the remaining challenges and opportunities for anticancer therapy.

  1. Supporting residents’ expression of sexuality: the initial construction of a sexuality assessment tool for residential aged care facilities

    PubMed Central

    2014-01-01

    Background Sexuality is a key component of quality of life and well-being and a need to express one’s sexuality continues into old age. Staff and families in residential aged care facilities often find expressions of sexuality by residents, particularly those living with dementia, challenging and facilities often struggle to address individuals’ needs in this area. This paper describes the development of an assessment tool which enables residential aged care facilities to identify how supportive their organisation is of all residents’ expression of their sexuality, and thereby improve where required. Methods Multi-phase design using qualitative methods and a Delphi technique. Tool items were derived from the literature and verified by qualitative interviews with aged care facility staff, residents and families. The final item pool was confirmed via a reactive Delphi process. Results A final item pool of sixty-nine items grouped into seven key areas allows facilities to score their compliance with the areas identified as being supportive of older people’s expression of their sexuality in a residential aged care environment. Conclusions The sexuality assessment tool (SexAT) guides practice to support the normalization of sexuality in aged care homes and assists facilities to identify where enhancements to the environment, policies, procedures and practices, information and education/training are required. The tool also enables facilities to monitor initiatives in these areas over time. PMID:24980463

    Snake bites are very common in India, particularly in West Bengal. Snake bite can cause various hematological, neuromyopathical complications. It can be very fatal if not detected and treated early. Timely intervention can save the patient. We are reporting a case of hematotoxic Russell viper snake bite presented with subarachnoid hemorrhage. Patient was successfully treated with antivenom serum (AVS) along with other conservative management. Subarachnoid hemorrhage as an initial presentation in viper bite is very rare and we discuss the case with proper literature review. PMID:26425018

    1998-07-01

    Discovery of a previously unknown Bronze Age civilization (Oxus Civilization) centered on the oases of Central Asia immediately raised questions concerning the origin and interregional impacts of this civilization. Fifteen craniometric variables from 12 Bronze Age samples--encompassing 544 adults from Central Asia, Iran, the Indus Valley, and Anatolia--are compared to test which, if any, of the current hypotheses offered by archaeologists are best supported by the pattern of phenetic affinities possessed by the Oxus Civilization inhabitants of the north Bactrian oasis. Craniometric differences between samples are compared with Mahalanobis generalized distance, and patterns of phenetic affinity are assessed with two types of cluster analysis (WPGMA, neighbor-joining method), multidimensional scaling, and principal coordinates analysis. Results obtained by this analysis indicate that current hypotheses for both the origin and interregional impacts of Oxus Civilization populations are incomplete. PMID:9696149

    BACKGROUND/OBJECTIVES South Korean's sodium consumption level is more than twice the upper limit level suggested by the WHO. Steep increases in the prevalence of hypertension and cardiovascular disease in Korea necessitate more effective sodium reduction programs. This study was conducted in order to compare sodium intake-related eating behaviors and key psychosocial factors according to age group and gender. SUBJECTS/METHODS Using an online survey, a total of 1,564 adults (20-59 years old) considered to be geographically representative of South Korea were recruited and surveyed. The major outcomes were perceived behaviors, knowledge, intentions, and self-efficacy related to sodium intake. RESULTS The results show that perceived behavior and level of self-efficacy related to low sodium consumption differed by age and gender. Female participants showed better behavior and intention towards low sodium intake than male counterparts. Young participants in their 20s showed the lowest intention to change their current sodium intake as well as lowest self-efficacy measures. CONCLUSIONS Future sodium reduction interventions should be developed with tailored messages targeting different age and gender groups. Specifically, interventions can be planned and implemented at the college level or for workers in their early career to increase their intention and self-efficacy as a means of preventing future health complications associated with high sodium intake.

    Elderly eminent academics and blue-collar workers were compared with Doctor of Philosophy students and trade apprentices to investigate whether intelligence and memory deteriorate at a slower rate in persons with high ability. The elderly groups showed decline on tests of perceptual-motor speed, visuospatial reasoning, inferential thinking and memory relative to the young subjects. Initial ability determined the level of intellectual performance, such that elderly academics maintained their initial advantage over the elderly blue-collar workers. However, with the exception of the Similarities subtest of the Wechsler Adult Intelligence Scale, the rate of change on tests of memory and intelligence did not differ for the high- and low-ability groups. The hypothesis that high ability is associated with a slower rate of cognitive decline was not supported. PMID:1780406

    OBJECTIVE Although nonattendance at initial appointments in mental health services is a substantial problem, the phenomenon is poorly understood. This review synthesized findings of randomized controlled trials (RCTs) of interventions to increase initial appointment attendance and determined whether theories or models contributed to intervention design. METHODS Six electronic databases were systematically searched, and reference lists of identified studies were also examined. Studies included were RCTs (including "quasi-randomized" controlled trials) that compared standard practice with an intervention to increase attendance at initial appointments in a sample of adults who had a scheduled initial appointment in a mental health or substance abuse service setting. RESULTS Of 144 potentially relevant studies, 21 met inclusion criteria. These studies were reported in 20 different research papers. Of these, 16 studies (N=3,673 participants) were included in the analyses (five were excluded because they reported only nonattendance at the initial appointment). Separate analyses were conducted for each intervention type (opt-in systems, telephone reminders and prompts, orientation and reminder letters, accelerated intake, preappointment completion of psychodynamic questionnaires, and "other"). Narrative synthesis was used for analysis because the high level of heterogeneity between studies precluded a meta-analysis. The results were mixed for all types of intervention. Some isolated high-quality studies of opt-in systems, orientation and reminder letters, and more novel interventions demonstrated a beneficial effect. CONCLUSIONS The synthesized findings indicated that orientation and reminder letters may have a small beneficial effect. Consistent evidence for the efficacy of other types of common interventions is lacking. More novel interventions, such as asking clients to formulate plans to deal with obstacles to attendance and giving clients a choice of therapist style

    Introduction Elder abuse, a universal human rights problem, is associated with many negative consequences. In most jurisdictions, however, there are no comprehensive hospital-based interventions for elder abuse that address the totality of needs of abused older adults: psychological, physical, legal, and social. As the first step towards the development of such an intervention, we undertook a systematic scoping review. Objectives Our primary objective was to systematically extract and synthesize actionable and applicable recommendations for components of a multidisciplinary intersectoral hospital-based elder abuse intervention. A secondary objective was to summarize the characteristics of the responses reviewed, including methods of development and validation. Methods The grey and scholarly literatures were systematically searched, with two independent reviewers conducting the title, abstract and full text screening. Documents were considered eligible for inclusion if they: 1) addressed a response (e.g., an intervention) to elder abuse, 2) contained recommendations for responding to abused older adults with potential relevance to a multidisciplinary and intersectoral hospital-based elder abuse intervention; and 3) were available in English. Analysis The extracted recommendations for care were collated, coded, categorized into themes, and further reviewed for relevancy to a comprehensive hospital-based response. Characteristics of the responses were summarized using descriptive statistics. Results 649 recommendations were extracted from 68 distinct elder abuse responses, 149 of which were deemed relevant and were categorized into 5 themes: Initial contact; Capacity and consent; Interview with older adult, caregiver, collateral contacts, and/or suspected abuser; Assessment: physical/forensic, mental, psychosocial, and environmental/functional; and care plan. Only 6 responses had been evaluated, suggesting a significant gap between development and implementation of

    Although certainly one of the most recognizable characteristics of human biology, aging remains one of the least understood. This is largely attributable to the fact that aging is both gradual and inherently complex, with almost all aspects of physiology and phenotype undergoing steady modification with advancing age. The complexity of the aging process does not allow for a single all-encompassing definition, yet decades of study using diverse systems, methodologies, and model organisms have begun to build a consensus regarding the central physiological characteristics of aging. Indeed, such studies have shown that the process of aging is invariably accompanied by a diminished capacity to adequately maintain tissue homeostasis or to repair tissues after injury. When homeostatic control diminishes to the point at which tissue/organ integrity and function are no longer sufficiently maintained, physiologic decline ensues, and aging is manifested. Inadequate organ homeostasis indicates possible dysfunction of tissue-specific stem cells. Several mechanisms have been postulated to account for age-related cellular changes; however, increasing literature evidence suggests that age-related changes to the epigenome make a major contribution to the aged phenotype. In this review, we discuss the evidence for epigenetic contributions to tissue-specific stem cell ageing. PMID:24740867

    Objectives To assess whether, compared with previous years, hospital care became safer in 2011/2012, expressing itself in a fall in preventable adverse event (AE) rates alongside patient safety initiatives. Design Retrospective patient record review at three points in time. Setting In three national AE studies, patient records of 2004, 2008 and 2011/2012 were reviewed in, respectively, 21 hospitals in 2004, 20 hospitals in 2008 and 20 hospitals in 2011/2012. In each hospital, 400, 200 and 200 patient records were sampled, respectively. Participants In total, 15 997 patient admissions were included in the study, 7926 patient admissions from 2004, 4023 from 2008 and 4048 from 2011/2012. Interventions The main patient safety initiatives in hospital care at a national level between 2004 and 2012 have been small as well as large-scale multifaceted programmes. Main outcome measures Rates of both AEs and preventable AEs. Results Uncorrected crude overall AE rates showed no change in 2011/2012 in comparison with 2008, whereas preventable AE rates showed a reduction of 45%. After multilevel corrections, the decrease in preventable AE rate in 2011/2012 was still clearly visible with a decrease of 30% in comparison to 2008 (p=0.10). In 2011/2012, fewer preventable AEs were found in older age groups, or related to the surgical process, in comparison with 2008. Conclusions Our study shows some improvements in preventable AEs in the areas that were addressed during the comprehensive national safety programme. There are signs that such a programme has a positive impact on patient safety. PMID:26150548

    In this study, data obtained from Sm-Nd and Rb-Sr isotopic measurements of lunar highlands’ samples are renormalized to common standard values and then used to define ages with a common isochron regression algorithm. The reliability of these ages is evaluated using five criteria that include whether: (1) the ages are defined by multiple isotopic systems, (2) the data demonstrate limited scatter outside uncertainty, (3) initial isotopic compositions are consistent with the petrogenesis of the samples, (4) the ages are defined by an isotopic system that is resistant to disturbance by impact metamorphism, and (5) the rare-earth element abundances determined by isotope dilution of bulk of mineral fractions match those measured by in situ analyses. From this analysis, it is apparent that the oldest highlands’ rock ages are some of the least reliable, and that there is little support for crustal ages older than ~4.40 Ga. A model age for ur-KREEP formation calculated using the most reliable Mg-suite Sm-Nd isotopic systematics, in conjunction with Sm-Nd analyses of KREEP basalts, is 4389 ± 45 Ma. This age is a good match to the Lu-Hf model age of 4353 ± 37 Ma determined using a subset of this sample suite, the average model age of 4353 ± 25 Ma determined on mare basalts with the 146Sm-142Nd isotopic system, with a peak in Pb-Pb ages observed in lunar zircons of ~4340 ± 20 Ma, and the oldest terrestrial zircon age of 4374 ± 6 Ma. The preponderance of ages between 4.34 and 4.37 Ga reflect either primordial solidification of a lunar magma ocean or a widespread secondary magmatic event on the lunar nearside. The first scenario is not consistent with the oldest ages reported for lunar zircons, whereas the second scenario does not account for concordance between ages of crustal rocks and mantle reservoirs.

    Background: Pharmacy students can help protect the public from vaccine-preventable diseases by participating in immunization initiatives, which currently exist in some Canadian and American jurisdictions. The objective of this article is to critically review evidence of student impact on public health through their participation in vaccination efforts. Methods: PubMed, CINAHL, Cochrane Database, EMBASE, International Pharmaceutical Abstracts, Scopus and Web of Science electronic databases were searched for peer-reviewed literature on pharmacy student involvement in vaccination programs and their impact on public health. Papers were included up to November 17, 2015. Two reviewers independently screened titles and abstracts and extracted data from eligible full-text articles. Results: Eighteen titles met all inclusion criteria. All studies were published between 2000 and 2015, with the majority conducted in the United States (n = 12). The number of vaccine doses administered by students in community-based clinics ranged from 109 to 15,000. Increases in vaccination rates in inpatient facilities ranged from 18.5% to 68%. Across studies, student-led educational interventions improved patient knowledge of vaccines and vaccine-preventable diseases. Patient satisfaction with student immunization services was consistently very high. Discussion: Methodology varied considerably across studies. The literature suggests that pharmacy students can improve public health by 1) increasing the number of vaccine doses administered, 2) increasing vaccination rates, 3) increasing capacity of existing vaccination efforts, 4) providing education about vaccines and vaccine-preventable diseases and 5) providing positive immunization experiences. Conclusion: Opportunities exist across Canada to increase pharmacy student involvement in immunization efforts and to assess the impact of their participation. Greater student involvement in immunization initiatives could boost immunization rates

  14. Impact of Pneumococcal Conjugate Vaccine Administration in Pediatric Older Age Groups in Low and Middle Income Countries: A Systematic Review

    2015-01-01

    Introduction Pneumococcal conjugate vaccine (PCV) is included in the World Health Organization’s routine immunization schedule and is recommended by WHO for vaccination in high-risk children up to 60 months. However, many countries do not recommend vaccination in older age groups, nor have donors committed to supporting extended age group vaccination. To better inform decision-making, this systematic review examines the direct impact of extended age group vaccination in children over 12 months in low and middle income countries. Methods An a priori protocol was used. Using pre-specified terms, a search was conducted using PubMed, LILACS, Cochrane Infectious Diseases Group Specialized Register, Cochrane Central Register of Controlled Trials, CAB Abstracts, clinicaltrials.gov and the International Symposium on Pneumococci and Pneumococcal Diseases abstracts. The primary outcome was disease incidence, with antibody titers and nasopharyngeal carriage included as secondary outcomes. Results Eighteen studies reported on disease incidence, immune response, and nasopharyngeal carriage. PCV administered after 12 months of age led to significant declines in invasive pneumococcal disease. Immune response to vaccine type serotypes was significantly higher for those vaccinated at older ages than the unimmunized at the established 0.2ug/ml and 0.35ug/ml thresholds. Vaccination administered after one year of age significantly reduced VT carriage with odds ratios ranging from 0.213 to 0.69 over four years. A GRADE analysis indicated that the studies were of high quality. Discussion PCV administration in children over 12 months leads to significant protection. The direct impact of PCV administration, coupled with the large cohort of children missed in first year vaccination, indicates that countries should initiate or expand PCV immunization for extended age group vaccinations. Donors should support implementation of PCV as part of delayed or interrupted immunization for older

    Multiple myeloma is a malignant plasma-cell disorder that primarily involves the bone marrow, but extramedullary involvement is becoming increasingly common (Bladé et al., 2012) both at initial presentation and follow-up. Most common initial presentations for multiple myeloma include generalized fatigue, renal insufficiency, bone pain, and recurrent bacterial infections. We present a case of a healthy 55-year-old man that presented to the emergency department with a three-week history of anorexia and jaundice without any past medical history. Patient's initial labs were significant for hyperbilirubinemia and elevated liver function enzymes (AST, ALT, ALP, and GGT). Additional laboratory workup was significant for mild hypercalcemia and increased protein gap. MRI and ERCP suggested primary sclerosing cholangitis but were not diagnostic. Liver biopsy illustrated plasma-cell infiltration and bone marrow biopsy diagnosed multiple myeloma with extramedullary disease. Patient was started on dexamethasone, bortezomib, and cyclophosphamide, but, despite this aggressive regimen, the patient continued to decline. We take this opportunity to present this atypical presentation of a common hematological malignancy and review the associated literature. PMID:26221143

    Knowledge and training in evidence-based medicine is essential for informed clinical decision-making and treatment choices. Systematic reviews identify, appraise and synthesize research-based evidence and present it in accessible format. The Indian Council of Medical Research has promoted evidence-based medicine in India by establishing an Advanced Center for evidence based medicine that hosted the South Asian Cochrane Network and Center at the Christian Medical College, Vellore; procuring a national subscription to The Cochrane Library making it accessible to all Indian scientists; and establishing a Center for Advanced research on evidence- based child health at Post Graduate Institute of Medical Education and Research, Chandigarh. This article informs about a national level initiative by ICMR that aims to harness the translational potential of secondary research, by funding systematic reviews aligned to national health priorities selected through a national competitive process; and to provide training, mentoring, and quality assurance. A continuing scheme of funding high-quality systematic reviews on priority areas of Child Health may follow. PMID:25848991

    The EarthScope AGeS (Awards for Geochronology Student Research) program is a multi-year educational initiative aimed at enhancing interdisciplinary, innovative, and high-impact science by promoting training and new interactions between students, scientists, and geochronology labs at different institutions. The program offers support of up to $10,000 for graduate students to collect and interpret geochronology data that contribute to EarthScope science targets through visits to participating geochronology labs (www.earthscope.org/geochronology). The program was launched by a 2-day short course held before the 2014 National GSA meeting in Vancouver, at which 16 geochronology experts introduced 43 participants to the basic theory and applications of geochronology methods. By the first proposal submission deadline in spring 2015, 33 labs representing a broad range of techniques had joined the program by submitting lab plans that were posted on the EarthScope website. The lab plans provide information about preparation, realistic time frames for visits, and analytical costs. In the first year of the program, students submitted 47 proposals from 32 different institutions. Proposals were ranked by an independent panel, 10 were funded, and research associated with these projects is currently underway. The next proposal deadline will be held in spring 2016. The 4D-Earth initiative is an idea for a natural successor to the EarthScope program aimed at expanding the primarily 3D geophysical focus that captured a snapshot of present day North America into the 4th dimension of time (hence the connection to the prototypical AGeS program), and illuminating the crustal component that was below the resolution of much of the USArray image. Like EarthScope, the notion is that this initiative would integrate new infrastructure and usher in a new way of doing science. The overarching scientific motivation is to develop a Community Geologic Model for the 4-D Evolution of the North

    Objective: To systematically collate and evaluate the evidence from recent SRs of bevacizumab for neo-vascular age related macular degeneration. Materials and Methods: Literature searches were carried out in Medline, Embase, Cochrane databases for all systematic reviews (SRs) on the effectiveness of bevacizumab for neo-vascular age related macular degeneration, published between 2000 and 2013. Titles and abstracts were assessed against the inclusion/exclusion criteria using Joanna Briggs Institute (JBI) study eligibility form. Data was extracted using the JBI data extraction form. The quality of the SRs was assessed using JBI critical appraisal checklist for SRs. Decisions on study eligibility and quality were made by two reviewers; any disagreements were resolved by discussion. Results: Nine relevant reviews were identified from 30 citations, of which 5 reviews fulfilled the review's inclusion criteria. All 5 reviews showed bevacizumab to be effective for neovascular AMD in the short-term when used alone or in combination with PDT or Pegaptanib. The average quality score of the reviews was 7; 95% confidence interval 6.2 to 7.8 (maximum possible quality score is 10). The selection and publication bias were not addressed in all included reviews. Three-fifth of the reviews had a quality score of 7 or lower, these reviews had some methodological limitations, search strategies were only identified in 2 (40%) reviews, independent study selection and quality assessment of included studies (4 (80%)) were infrequently performed. Conclusion: Overall, the reviews on the effectiveness of intravitreal/systemic bevacizumab for neovascularage-related macular generation (AMD) received good JBI quality scores (mean score = 7.0 points), with a few exceptions. The study also highlights the suboptimal reporting of SRs on this topic. Reviews with poor methodology may limit the validity of the reported results; hence efforts should be made to improve the design, reporting and

    The causes of slip and fall accidents, both in terms of extrinsic and intrinsic factors and their associations are not yet fully understood. Successful intervention solutions for reducing slip and fall accidents require a more complete understanding of the mechanisms involved. Before effective fall prevention strategies can be put into practice, it is central to examine the chain of events in an accident, comprising the exposure to hazards, initiation of events and the final outcome leading to injury and disability. These events can be effectively identified and analyzed by applying epidemiological, psychophysical, biomechanical and tribological research principles and methodologies. In this manuscript, various methods available to examine fall accidents and their underlying mechanisms are presented to provide a comprehensive array of information to help pinpoint the needs and requirements of new interventions aimed at reducing the risk of falls among the growing elderly population.

    Interest in oxytocin has increased rapidly over the last decades. Consequently, quite a number of studies have addressed the influence of oxytocin on social stress, perception, cognition, and decision making in healthy adults as well as in clinical samples characterized by some form of social disturbance. Surprisingly little research on oxytocin has focused on ageing populations. This is particularly striking in two areas of study: the role of oxytocin in grandparents' behavior toward and bonding with their grandchildren and the effects of oxytocin on the neurocognitive processing of socioemotional stimuli. The current mini-review offers an overview of the literature on the involvement of oxytocin in parental behavior and neurocognitive functioning, and discusses the relevance of these findings to ageing individuals. As the literature shows that oxytocin is profoundly involved in parenting and in bonding throughout life, it is highly likely that oxytocin plays a role in grandparenting and bonding between grandparents and grandchildren as well. However, results obtained with younger adults may not be directly applicable to older individuals in yet another type of relationship. The possibility that age-related changes occur in the oxytocin system (which is at present unclear) must be taken into account. In addition, ageing impairs neurocognitive processes that are profoundly affected by oxytocin (including some aspects of memory and emotion recognition) and is associated with alterations in both structure and function of the amygdala, which is prominently involved in mediating effects of oxytocin. Research investigating the ageing oxytonergic system and studies focusing on the involvement of oxytocin in socioemotional neurocognitive processes and social behavior in elderly individuals, including grandparents, are therefore urgently needed.

    Inflammatory process mediated by innate and adaptive immune systems is a major pathogenic mechanism of renal ischemia-reperfusion injury (IRI). There are concerns that organ recipients may be at increased risk of developing IRI after receiving kidneys from elder donors. To reveal the effects of aging on the development of renal IRI, we compared the immunologic micromilieu of normal and postischemic kidneys from mice of three different ages (9 wk, 6 mo, and 12 mo). There was a higher number of total T cells, especially effector memory CD4/CD8 T cells, and regulatory T cells in the normal kidneys of old mice. On day 2 after IRI, the proportion of necrotic tubules and renal functional changes were comparable between groups although old mice had a higher proportion of damaged tubule compared with young mice. More T cells, but less B cells, trafficked into the postischemic kidneys of old mice. The infiltration of NK T cells was similar across the groups. Macrophages and neutrophils were comparable between groups in both normal kidneys and postischemic kidneys. The intrarenal expressions of TNF-α and VEGF were decreased in normal and postischemic kidneys of aged mice. These mixed effects of aging on lymphocytes and cytokines/chemokines were not different between the two groups of old mice. Our study demonstrates that aging alters the intrarenal micromilieu but has small effects on the development of initial renal injury after IRI. Further study investigating aging-dependent differences in the repair process of renal IRI may be required. PMID:26661651

  5. The potential effects of meditation on age-related cognitive decline: a systematic review

    2014-01-01

    With a rapidly aging society it becomes increasingly important to counter normal age-related decline in cognitive functioning. Growing evidence suggests that cognitive training programs may have the potential to counteract this decline. On the basis of a growing body of research that shows that meditation has positive effects on cognition in younger and middle-aged adults, meditation may be able to offset normal age-related cognitive decline or even enhance cognitive function in older adults. In this paper, we review studies investigating the effects of meditation on age-related cognitive decline. We searched the Web of Science (1900 to present), PsycINFO (1597 to present), MEDLINE (1950 to present), and CABI (1910 to present) to identify original studies investigating the effects of meditation on cognition and cognitive decline in the context of aging. Twelve studies were included in the review, six of which were randomized controlled trials. Studies involved a wide variety of meditation techniques and reported preliminary positive effects on attention, memory, executive function, processing speed, and general cognition. However, most studies had a high risk of bias and small sample sizes. Reported dropout rates were low and compliance rates high. We conclude that meditation interventions for older adults are feasible, and preliminary evidence suggests that meditation can offset age-related cognitive decline. PMID:24571182

    2016-01-01

    Natural adult aging is associated with many functional impairments of the human neuromuscular system. One of the more observable alterations is the loss of contractile muscle mass, termed sarcopenia. The loss of muscle mass occurs primarily due to a progressive loss of viable motor units, and accompanying atrophy of remaining muscle fibers. Not only does the loss of muscle mass contribute to impaired function in old age, but alterations in fiber type and myosin heavy chain isoform expression also contribute to weaker, slower, and less powerful contracting muscles. This review will focus on motor unit loss associated with natural adult aging, age-related fatigability, and the age-related differences in strength across contractile muscle actions. PMID:27011872

    Objective To quantify progress with the initiation of salt reduction strategies around the world in the context of the global target to reduce population salt intake by 30% by 2025. Methods A systematic review of the published and grey literature was supplemented by questionnaires sent to country program leaders. Core characteristics of strategies were extracted and categorised according to a pre-defined framework. Results A total of 75 countries now have a national salt reduction strategy, more than double the number reported in a similar review done in 2010. The majority of programs are multifaceted and include industry engagement to reformulate products (n = 61), establishment of sodium content targets for foods (39), consumer education (71), front-of-pack labelling schemes (31), taxation on high-salt foods (3) and interventions in public institutions (54). Legislative action related to salt reduction such as mandatory targets, front of pack labelling, food procurement policies and taxation have been implemented in 33 countries. 12 countries have reported reductions in population salt intake, 19 reduced salt content in foods and 6 improvements in consumer knowledge, attitudes or behaviours relating to salt. Conclusion The large and increasing number of countries with salt reduction strategies in place is encouraging although activity remains limited in low- and middle-income regions. The absence of a consistent approach to implementation highlights uncertainty about the elements most important to success. Rigorous evaluation of ongoing programs and initiation of salt reduction programs, particularly in low- and middle- income countries, will be vital to achieving the targeted 30% reduction in salt intake.

    Criteria for computed tomography (CT) to head injured infants have not been established. Since the identification of neurological findings is difficult in infants, examination by CT may be necessary in some cases, but it may be difficult to perform CT because of problems with radiation exposure and body movement. Moreover, even though no intracranial abnormality was found immediately after injury, abnormal findings may appear after several hours. From this viewpoint, course observation after injury may be more important than CT in the initial treatment of head trauma in infants. The complaints and neurological manifestations of infants, particularly those aged 2 or younger, are frequently unclear; therefore, there is an opinion that CT is recommended for all pediatric patients. However, the appropriateness of its use should be determined after confirming the mechanism of injury, consciousness level, neurological findings, and presence/absence of a history of abuse. Among the currently available rules specifying criteria for CT of infants with head trauma, the Pediatric Emergency Care Applied Research Network (PECARN) study may be regarded as reliable at present. In Japan, where the majority of emergency hospitals are using CT, it may be necessary to develop criteria for CT in consideration of the actual situation. CT diagnosis for pediatric head trauma is not always necessary. When no imaging is performed, this should be fully explained at the initial treatment before selecting course observation at home. Checking on a state of the patients by telephone is useful for both patients and physicians. PMID:27194179

    The development of health and healthcare systems in South-East Asia has influenced the practice of community pharmacy. Over the years, community pharmacy in the region has striven to expand services beyond dispensing to encompass more involvement in public health issues. Searches were conducted in Scopus, EMBASE, MEDLINE and PubMed for articles published between January 2000 and December 2014, with 21 studies in five countries meeting the inclusion criteria. The findings showed increasing interest in research into the delivery of pharmacy services and public health initiatives. Overall, the review found that provision of some health services in pharmacies was common; however, most public health initiatives appeared to be poorly implemented, had limited evidence and were not demonstrated to be sustainable across the sector. This indicates that the practice of community pharmacy in the region has not significantly changed over the past 14 years with respect to the scope and quality of pharmacy services provided, and fundamental policy changes are necessary to improve this situation.

    An initial review was conducted of the current treatment operations for remediation of groundwater contaminated with trichloroethene (TCE) at the Fort lewis Logistics Center. Results from this review indicate the two pump-and-treat systems are effectively containing the TCE plume within the upper unconfined aquifer (Vashon Drift). However, mass balance calculations show the existing treatment systems alone will not accomplish the remedial action objective of cleaning up the aquifer to drinking water standards within 30 years as specified in the Record of Decision (ROD). This conclusion is based on the estimated mass of TCE at the source term (51,000 kg), the calculated mass of TCE in the aquifer (4,900 kg), and the removal rate of the pump-and-treat systems that currently ranges from 324 to 667 kg of TCe per year. Four areas within the TCE plume have been identified where enhancements could be made to the existing treatment operations. These are, Area 1 -- the vadose zone source, Area 2 -- the saturated zone source, Area 3 -- a containment area down gradient of Areas 1 and 2, and Area 4 -- the remainder of the plume. This report lists several remedial technologies including new and innovative technologies for these four areas that may help clean up the site to regulatory acceptable levels, shorten the timeframe for cleanup, or significantly reduce currently estimated Installation Restoration program (IRP) life-cycle costs.

    Abstract This review shows the potential ground-breaking impact that mathematical tools may have in the analysis and the understanding of the HIV dynamics. In the first part, early diagnosis of immunological failure is inferred from the estimation of certain parameters of a mathematical model of the HIV infection dynamics. This method is supported by clinical research results from an original clinical trial: data just after 1 month following therapy initiation are used to carry out the model identification. The diagnosis is shown to be consistent with results from monitoring of the patients after 6 months. In the second part of this review, prospective research results are given for the design of individual anti-HIV treatments optimizing the recovery of the immune system and minimizing side effects. In this respect, two methods are discussed. The first one combines HIV population dynamics with pharmacokinetics and pharmacodynamics models to generate drug treatments using impulsive control systems. The second one is based on optimal control theory and uses a recently published differential equation to model the side effects produced by highly active antiretroviral therapy therapies. The main advantage of these revisited methods is that the drug treatment is computed directly in amounts of drugs, which is easier to interpret by physicians and patients. PMID:25371860

    2012-01-01

    Background. Policymakers need estimates of the impact of tobacco control (TC) policies to set priorities and targets for reducing tobacco use. We systematically reviewed the independent effects of TC policies on smoking behavior. Methods. We searched MEDLINE (through January 2012) and EMBASE and other databases through February 2009, looking for studies published after 1989 in any language that assessed the effects of each TC intervention on smoking prevalence, initiation, cessation, or price participation elasticity. Paired reviewers extracted data from studies that isolated the impact of a single TC intervention. Findings. We included 84 studies. The strength of evidence quantifying the independent effect on smoking prevalence was high for increasing tobacco prices and moderate for smoking bans in public places and antitobacco mass media campaigns. Limited direct evidence was available to quantify the effects of health warning labels and bans on advertising and sponsorship. Studies were too heterogeneous to pool effect estimates. Interpretations. We found evidence of an independent effect for several TC policies on smoking prevalence. However, we could not derive precise estimates of the effects across different settings because of variability in the characteristics of the intervention, level of policy enforcement, and underlying tobacco control environment.

    Introduction The conduct of structured benefit-risk assessment (BRA) of pharmaceutical products is a key area of interest for regulatory agencies and the pharmaceutical industry. However, the acceptance of a standardized approach and implementation are slow. Statisticians play major roles in these organizations, and have a great opportunity to be involved and drive the shaping of future BRA. Method We performed a literature search of recent reviews and initiatives assessing BRA methodologies, and grouped them to assist those new to BRA in learning, understanding, and choosing methodologies. We summarized the key points and discussed the impact of this emerging field on various stakeholders, particularly statisticians in the pharmaceutical industry. Results We provide introductory, essential, special interest, and further information and initiatives materials that direct readers to the most relevant materials, which were published between 2000 and 2013.  Based on recommendations in these materials we supply a toolkit of advocated BRA methodologies. Discussion Despite initiatives promoting these methodologies, there are still barriers, one of which being the lack of a consensus on the most appropriate methodologies among stakeholders. However, this opens up opportunities, for statisticians in the pharmaceutical industry especially, to champion appropriate BRA methodology use throughout the pharmaceutical product lifecycle. Conclusions This article may serve as a starting point for discussions and to reach a mutual consensus for methodology selection in a particular situation. Regulators and pharmaceutical industry should continue to collaborate to develop and take forward BRA methodologies, and by clear communication develop a mutual understanding of the key issues.

    Objective To test whether earlier age at weaning (age 3-6 months) may promote faster growth during infancy. Study design Weaning at age 3.0-7.0 months was reported by 571 mothers of term singletons in a prospective birth cohort study conducted in Cambridge, UK. Infant weight and length were measured at birth and at age 3 months and 12 months. Anthropometric values were transformed into age- and sex-adjusted z-scores. Three linear regression models were performed, including adjustment for confounders in a stepwise manner. Measurements at age 3 months, before weaning, were used to consider reverse causality. Results Almost three-quarters (72.9%) of infants were weaned before age 6 months. Age at weaning of 3.0-7.0 months was inversely associated with weight and length (but not with body mass index) at 12 months (both P ≤ .01, adjusted for maternal and demographic factors). These associations were attenuated after adjustment for type of milk feeding and weight or length at age 3 months (before weaning). Rapid weight gain between 0 and 3 months predicted subsequent earlier age at weaning (P = .01). Our systematic review identified 2 trials, both reporting null effects of age at weaning on growth, and 15 observational studies, with 10 reporting an inverse association between age at weaning and infant growth and 4 reporting evidence of reverse causality. Conclusion In high-income countries, weaning between 3 and 6 months appears to have a neutral effect on infant growth. Inverse associations are likely related to reverse causality. PMID:26073105

  2. Review of performance, medical, and operational data on pilot aging issues

    An extensive review of the literature and studies relating to performance, medical, operational, and legal data regarding pilot aging issues was performed in order to determine what evidence there is, if any, to support mandatory pilot retirement. Popular misconceptions about aging, including the failure to distinguish between the normal aging process and disease processes that occur more frequently in older individuals, continue to contribute to much of the misunderstanding and controversy that surround this issue. Results: Review of medical data related to the pilot aging issue indicate that recent improvement in medical diagnostics and treatment technology have made it possible to identify to a high degree individuals who are at risk for developing sudden incapacitating illness and for treating those with disqualifying medical conditions. Performance studies revealed that after controlling for the presence of disease states, older pilots are able to perform as well as younger pilots on many performance tasks. Review of accident data showed that older, healthy pilots do not have higher accident rates than younger pilots, and indeeed, evidence suggests that older pilots have an advantage in the cockpit due to higher experience levels. The Man-Machine-Mission-Environment interface of factors can be managed through structured, supervised, and enhanced operations, maintenance, flight reviews, and safety procedures in order to ensure safe and productive operations by reducing the margin of error and by increasing the margin of safety. Conclusions: There is no evidence indicating any specific age as an arbitrary cut-off point for pilots to perform their fight duties. A combination of regular medical screening, performance evaluation, enhanced operational maintenance, and safety procedures can most effectively ensure a safe pilot population than can a mandatory retirement policy based on arbitrary age restrictions.

  3. Correcting for initial Th in speleothems to obtain the age of calcite nucleation after a growth hiatus

    In addition to the many U-Th dated speleothem records (δ18O δ13C, trace elements) of past environmental change based on continuous phases of calcite growth, discontinuous records also provide important constraints for a wide range of past states of the Earth system, including sea levels, permafrost extent, regional aridity and local cave flooding. Chronological information about human activity or faunal evolution can also be obtained where calcite can be seen to overlie cave art or mammalian bones, for example. Among the important considerations when determining the U-Th age of calcite that nucleates on an exposed surface are (1) initial 230Th/232Th, which can be elevated and variable in some settings, and (2) growth rate and sub-sample density, where extrapolation is required. By way of example, we present sea level data based on U-Th ages of vadose speleothems (i.e. formed above the water table and distinct from 'phreatic' examples) from caves of the circum-Caribbean , where calcite growth was interrupted by rising sea levels and then reinitiated after regression. These estimates demand large corrections and derived sea level constraints are compared with alternative data from coral reef terraces, phreatic overgrowths on speleothems or indirect, proxy evidence from oxygen isotopes to constrain rates of ice volume growth. Flowstones from the Bahamas provide useful sea level constraints because they present the longest and most continuous records in such settings (a function of preservation potential in addition to hydrological routing) and also earliest growth post-emergence after sea level fall. We revisit estimates for sea level regression at the end of MIS 5 at ~ 80 ka (Richards et al, 1994; Lundberg and Ford, 1994) and make corrections for non-Bulk Earth initial Th contamination (230Th/232Th activity ratio > 10), based on isochron analysis of alternative stalagmites from the same settings and recent high resolution analysis. We also present new U-Th ages for

    Objectives: To review the evidence on the association between age and limited health literacy, overall and by health literacy test, and to investigate the mediating role of cognitive function. Method: The Embase, MEDLINE, and PsycINFO databases were searched. Eligible studies were conducted in any country or language, included participants aged ≥50 years, presented a measure of association between age and health literacy, and were published through September 2013. Results: Seventy analyses in 60 studies were included in the systematic review; 29 of these were included in the meta-analysis. Older age was strongly associated with limited health literacy in analyses that measured health literacy as reading comprehension, reasoning, and numeracy skills (random-effects odds ratio [OR] = 4.20; 95% confidence interval [CI]: 3.13–5.64). By contrast, older age was weakly associated with limited health literacy in studies that measured health literacy as medical vocabulary (random-effects OR = 1.19; 95% CI: 1.03–1.37). Evidence on the mediating role of cognitive function was limited. Discussion: Health literacy tests that utilize a range of fluid cognitive abilities and mirror everyday health tasks frequently observe skill limitations among older adults. Vocabulary-based health literacy skills appear more stable with age. Researchers should select measurement tests wisely when assessing health literacy of older adults. PMID:25504637

    Age related degradation effects in safety related systems of nuclear power plants should be managed to prevent safety margins from eroding below the acceptable limits provided in plant design bases. The Nuclear Plant Aging Research (NPAR) Pro- gram, conducted under the auspices of the U.S. Nuclear Regulatory Commission (NRC), Office of Nuclear Regulatory Research, and other related aging management programs are developing technical information on managing aging. The aging management process central to these efforts consists of three key elements: 1) selecting structures, systems, and components (SSCs) in which aging should be controlled; 2) understanding the mechanisms and rates of degradation in these SSCs; and 3) managing degradation through effective inspection, surveillance, condition monitoring, trending, record keeping, mainten- ance, refurbishment, replacement, and adjustments in the operating environment and service conditions. This document concisely reviews and integrates information developed under the NPAR Program and other aging management studies and other available information related to understanding and managing age-related degradation effects and provides specific refer- ences to more comprehensive information on the same subjects.

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

  7. Neurodevelopment and brain growth in classic Menkes disease is influenced by age and symptomatology at initiation of copper treatment.

    Menkes disease is an X-linked recessive disorder of brain copper metabolism caused by mutations in an essential mammalian copper transport gene, ATP7A. Untreated affected individuals suffer failure to thrive and neurodevelopmental delays that usually commence at 6-8 weeks of age. Death by age three years is typical. While provision of working copies of ATP7A to the brain by viral vectors is a promising strategy under development, the only treatment currently available is subcutaneous copper injections. These can normalize circulating blood levels and may replete brain copper depending on the molecular context, e.g., the severity of ATP7A mutation and potential presence of mosaicism. In this paper, we summarize somatic growth and neurodevelopmental outcomes for 60 subjects enrolled in a recently concluded phase I/II clinical trial of copper histidine for Menkes disease (ClinicalTrials.gov Identifier: NCT00001262). Primary outcomes indicate highly statistically significant improvements in gross motor, fine motor/adaptive, personal-social, and language neurodevelopment in the cohort of subjects who received early treatment prior to onset of symptoms (n=35). Correlating with these findings, quantitative parameters of somatic growth indicated statistically significant greater growth in head circumference for the initially asymptomatic group, whereas weight and height/length at age three years (or at time of death) did not differ significantly. Mortality at age 3 was higher (50%) in subjects older and symptomatic when treatment commenced compared to the asymptomatic group (28.6%). We conclude that early copper histidine for Menkes disease is safe and efficacious, with treatment outcomes influenced by the timing of intervention, and ATP7A mutation. PMID:25281031

    Introduction: Robotic-assisted simple prostatectomy (RASP) has been touted as an alternative to open simple prostatectomy (OSP) to treat large gland benign prostatic hyperplasia. Our study assesses our institution’s experience with RASP and reviews the literature. Methods: We performed a retrospective chart review from January 2011 to November 2013 of all patients undergoing RASP and OSP. Operative and 90-day outcomes, including operation time, intraoperative blood loss, length of hospital stay (LOS), transfusion requirements, and complication rates, were assessed. Results: Thirty-two patients were identified: 4 undergoing RASP and 28 undergoing OSP. There was no difference in mean age at surgery (69.3 vs. 75.2 years; p = 0.17), mean Charlson Comorbidity Index (2.5 vs. 3.5; p = 0.19), and mean prostate volume on TRUS (239 vs. 180 mL; p = 0.09) in the robotic and open groups, respectively. There was a significant difference in the mean length of operation, with RASP exceeding OSP (161 vs. 79 min; p = 0.008). The mean intraoperative blood loss was significantly higher in the open group (835.7 vs. 218.8 mL; p = 0.0001). Mean LOS was shorter in the RASP group (2.3 vs. 5.5 days; p = 0.0001). No significant differences were noted in the 90-day transfusion rate (p = 0.13), or overall complication rate at 0% with RASP vs. 57.1% with OSP (p = 0.10). Conclusions: Our data suggest RASP has a shorter LOS and lower intraoperative volume of blood loss, with the disadvantage of a longer operating time, compared to OSP. It is a feasible technique and deserves further investigation and consideration at Canadian centres performing robotic prostatectomies. PMID:26425225

    2014-01-01

    Background: Natural and man-made disasters are prevailing in Ethiopia mainly due to drought, floods, landslides, earthquake, volcanic eruptions, and disease epidemics. Few studies so far have critically reviewed about medical responses to disasters and little information exists pertaining to the initiatives being undertaken by health sector from the perspective of basic disaster management cycle. This article aimed to review emergency health responses to disasters and other related interventions which have been undertaken in the health sector. Methods: Relevant documents were identified by searches in the websites of different sectors in Ethiopian and international non-governmental organizations and United Nations agencies. Using selected keywords, articles were also searched in the data bases of Medline, CINAHL, Scopus, and Google Scholar. In addition, pertinent articles from non-indexed journals were referred to. Results: Disaster management system in Ethiopia focused on response, recovery, and rehabilitation from 1974 to 1988; while the period between 1988 and 1993 marked the transition phase towards a more comprehensive approach. Theoretically, from 1993 onwards, the disaster management system has fully integrated the mitigation, prevention, and preparedness phases into already existing response and recovery approach, particularly for drought. This policy has changed the emergency response practices and the health sector has taken some initiatives in the area of emergency health care. Hence, drought early warning system, therapeutic feeding program in hospitals, health centers and posts in drought prone areas to manage promptly acute malnutrition cases have all been put in place. In addition, public health disease emergencies have been responded to at all levels of health care system. Conclusions: Emergency health responses to drought and its ramifications such as acute malnutrition and epidemics have become more comprehensive in the context of basic disaster

    Although it is assumed that most mammals experience growth plate closure and cessation of bone growth soon after sexual maturity, bone growth in rats continues throughout their lifespan. The rat was compared to other laboratory animals to assess differences in the duration of bone growth and its relationship to age at sexual maturity and lifespan. We reviewed the literature from 1966 to March 1999 by searching MEDLINE and other databases. Growth closure times and age at sexual maturity were retrieved for the mouse, rabbit, dog, cat, sheep, cow, horse, nonhuman primates, and human. For all species, we calculated the ratios of: 1) age at growth plate closure to lifespan, 2) age at growth plate closure to age at sexual maturity, and 3) age at sexual maturity to average lifespan. The ratio of age at physis closure to the average lifespan was large for the rat (22 to 35) and showed some overlap with that of humans (17 to 25); this ratio was comparatively small in all other nonhuman species (range, 4 to 17). This finding indicates that bone growth continues in the rat for a greater proportion of their lifespan than does that in other species. The ratio of age at physis closure to age at sexual maturity was larger for the rat (5 to 6) than that for other species, indicating that bone growth continues much longer after sexual maturity in rats than in other animals. The ratio of age at sexual maturity to average lifespan was largest for humans and nonhuman primates (13 to 14), indicating the increased time to reach puberty versus that in other species. These differences are important for studies in which animal models are used in research involving bone growth. PMID:12213043

    2015-01-01

    Purpose of the Study: The purpose of this study was to analyze the range of critiques of successful aging models and the suggestions for improvement as expressed in the social gerontology literature. Design and Methods: We conducted a systematic literature review using the following criteria: journal articles retrieved in the Abstracts in Social Gerontology, published 1987–2013, successful aging/ageing in the title or text (n = 453), a critique of successful aging models as a key component of the article. Sixty-seven articles met the criteria. Qualitative methods were used to identify key themes and inductively configure meanings across the range of critiques. Results: The critiques and remedies fell into 4 categories. The Add and Stir group suggested a multidimensional expansion of successful aging criteria and offered an array of additions. The Missing Voices group advocated for adding older adults’ subjective meanings of successful aging to established objective measures. The Hard Hitting Critiques group called for more just and inclusive frameworks that embrace diversity, avoid stigma and discrimination, and intervene at structural contexts of aging. The New Frames and Names group presented alternative ideal models often grounded in Eastern philosophies. Implications: The vast array of criteria that gerontologists collectively offered to expand Rowe and Kahn’s original successful model is symptomatic of the problem that a normative model is by definition exclusionary. Greater reflexivity about gerontology’s use of “successful aging” and other normative models is needed. PMID:24814830

    2009-01-01

    This short review portrays the evolutionary theories of aging in the light of the existing discoveries from genomic and molecular genetic studies on aging and longevity. At the outset, an historical background for the development of the evolutionary theories of aging is presented through the works of August Weismann (programmed death and the germ plasm theories) including his exceptional theoretical postulation, later experimentally validated by the existence of cell division limits. Afterwards, the theory of mutation accumulation of Peter Medawar and the theory modification by Charlesworth (late-life mortality plateau) are presented as well as the antagonistic pleiotropy hypothesis of George Williams, and the disposable soma theory of Kirkwood and Holliday. These theories are discussed in the light of the different research studies, which include studies on insulin signaling and longevity, the possibility that nuclear factor kappa B may be a major mediator of aging, studies of anti-aging Sirtuins and studies on heat shock proteins and longevity and on gene sets as biomarkers of aging. Finally, the proposals for future research in biogerontology, such as studies on the control of protein synthesis, validation of biomarkers of aging, understanding the biochemistry of longevity and research in the field of gerontologic pathology are presented. Likewise, further attention is suggested regarding the work on telomere shortening, stem cells and studies on understanding the biochemical and molecular basis for longevity in centenarians.

    Older drivers are at greatest risk for injury or death as a result of a car crash. In this mini-review we outline the normative age-related changes to perceptual, cognitive, and motor abilities that contribute to increased crash risk and decreased comfort with driving, and highlight specific driving scenarios and conditions that are particularly challenging for aging road users. Adopting a person-environment fit framework, we discuss how the roadway environment can be modified to better match the abilities of the aging driver. We also review evidence for the efficacy of training interventions intent on changing the abilities and strategies of the aging driver to better match the demands of the driving environment. Evidence suggests that specific changes to the roadway and driver training strategies can bring the abilities of the older driver back into alignment with the demands of the driving task. A focus on both approaches will help ensure the safety of all road users as the number of aging road users greatly increases over the next few decades. PMID:23989044

    Objective This study seeks to better understand the prevalence and severity of secondary health conditions in individuals with post-polio syndrome (PPS), and the association between these conditions and aging. Design A scoping literature review was conducted searching electronic databases for studies published from 1986 – 2011. The scoping review provided information regarding the prevalence and associations of secondary health conditions in PPS with age or other duration-related variables. Results The findings indicate that: (1) individuals with PPS experience a number of serious secondary health conditions; (2) the most common conditions or symptoms are fatigue, pain, respiratory and sleep complaints, and increased risk of falls; (3) reports of the associations between the frequency or severity of conditions and age-related factors are variable, perhaps because of methodological inconsistencies between studies; and (4) there is a marked lack of longitudinal research examining the natural course of health conditions in people aging with PPS. Conclusions Longitudinal research is needed to understand the course of health conditions and the impact of multiple secondary conditions in people aging with PPS. Efforts are also needed to develop and test the efficacy of interventions to prevent these health secondary conditions or reduce their negative impact. PMID:25122095

    The results of Stage 2 of the Regulatory Instrument Review are presented in this volume. Selected regulatory instruments, such as the Code of Federal Regulations (CFR), US Nuclear Regulatory Commission (NRC), Regulatory Guides, and ASME Codes, were investigated to determine the extent to which these regulations apply aging management to selected safety-related components in nuclear power plants. The Regulatory Instrument Review was funded by the NRC under the Nuclear Plant Aging Research (NPAR) program. Stage 2 of the review focused on four safety-related structures and components; namely, cables, containment and basemat, reactor coolant pumps, and motor-operated valves. The review suggests that the primary-emphasis of the regulatory instruments was on the design, construction, start-up, and operation of a nuclear power plant, and that aging issues were primarily addressed after an aging-related problem was recognized. This Stage 2 review confirms the results of the prior review; (see Regulatory Instrument Review: Management of Aging of LWR Major Safety-Related Components NUREG/CR-5490. The observations indicate that the regulations generally address management of age-related degradation indirectly. Specific age-related degradation phenomena frequently are dealt with in bulletins and notices or through generic issues, letters, etc. The major recommendation of this report, therefore, is that the regulatory instruments should more directly and explicitly address the aging phenomenon and the management of the age-related degradation process.

    Background: Existing guidelines on screening children less than 5 years of age for developmental delay vary. In this systematic review, we synthesized the literature on the effectiveness and harms of screening for developmental delay in asymptomatic children aged 1-4 years. Methods: We searched MEDLINE, Embase and PsychINFO for relevant articles published to June 16, 2015. We identified studies that included children aged 1-4 years who were not at high risk of developmental delay, screened in a primary care setting. Randomized trials and controlled cohort studies were considered for benefits (cognitive, academic and functional outcomes); no restrictions on study design were imposed for the review of harms. Results: Two studies were included. One used the Ages and Stages Questionnaire II for screening and reported significantly more referrals to early intervention in the intervention groups than in the control group (relative risk [RR] 1.95, 95% confidence interval [CI] 1.49-2.54, in the intervention group with office support and RR 1.71, 95% CI 1.30-2.25, in the intervention group without office support). The time to referral was 70% shorter in the intervention group with office support (rate ratio 0.30, 95% CI 0.19-0.48) and 64% shorter in the intervention group without office support (rate ratio 0.36, 95% CI 0.23-0.59), compared with the control group. The other study used the VroegTijdige Onderkenning Ontwikkelingsstoornissen Language Screening instrument to screen children aged 15 months at enrolment for language delay. It reported no differences between groups in academic performance outcomes at age 8 years. Interpretation: The evidence on screening for developmental delay in asymptomatic children aged 1-4 years is inconclusive. Further research with longer-term outcomes is needed to inform decisions about screening and screening intervals. PMID:27226967

    Although topical creams and other anti-aging products purport to reduce the appearance of aging and skin wrinkling, there has been no critical analysis in the scientific literature of their effectiveness. This systematic review critically evaluates the evidence for the effectiveness or efficacy of botanical treatments in reducing skin aging and wrinkling. MEDLINE, Embase, CINAHL®, CENTRAL and AMED databases were searched from their inception until October 2009. Reference lists of retrieved articles were hand-searched. Manufacturers and professional associations were contacted in order to identify further non-published studies. No language restrictions were applied. Only randomized clinical trials or controlled clinical trials assessing the effectiveness of botanical extracts in reducing wrinkling and aging of the skin were included. Data were extracted by two independent reviewers and methodological quality was assessed using the Jadad score and key aspects of the Cochrane risk of bias tool. Of 36 potentially relevant studies, 11 trials of botanical extracts for reducing skin wrinkling and the appearance of aging met all the inclusion criteria. No trials were identified following contact with anti-aging and cosmetic organizations, companies and professional bodies. A significant reduction in skin wrinkling was noted for date kernel extract, cork extract, soy extract, Rosaceae and peony extract. No significant reduction was noted for green tea, Vitaphenol® (a combination of green and white teas, mangosteen and pomegranate extract) or maca root. All trials were of poor methodological quality. Adverse effects were frequently not reported. In summary, there is some weak evidence to suggest that several botanical extracts may be effective in reducing the appearance of skin aging but no evidence that this effect is enduring. Independent replications with larger, more diverse samples, longer treatment durations and more rigorous study designs are required to validate

    Peroral endoscopic myotomy (POEM) is a new, purely endoscopic procedure for treatment of achalasia. Due to the lack of incisions POEM can be regarded as a true NOTES procedure. With POEM a myotomy is created in a similar fashion to the previous standard treatment, laparoscopic Heller myotomy (LHM). The relatively free choice of length and localization of the myotomy may be regarded as advantages of POEM. The procedure starts with a mucosal incision (mucosal entry) followed by preparation of a submucosal tunnel crossing the esophagogastric junction and creation of a myotomy in an antegrade direction before the mucosal access is closed with endoscopic clip placement. Since the first description of the application of POEM in humans in 2010 by the pioneer Haruhiro Inoue, Yokohama, Japan, it has been used increasingly and investigated in some centers in Asia, the U.S.A. and also Europe. The results are very promising. Although the procedure is technically demanding it can be performed safely with low complication rates. The POEM procedure achieves very good control of dysphagia and gastroesophageal reflux witch is only a rare side-effect witch is well-controllable with proton pump inhibitors (PPI). We review the currently available data from the literature and present our own initial series of  14 patients treated with POEM. PMID:24352827

    Australian emergency departments are experiencing an increasing demand for their services. Patient throughput continues to expand resulting in overcrowding and access block where patients cannot gain entry to appropriate hospital beds. This is despite both state and federal governments implementing numerous schemes to address the complex causes of stress on emergency departments. This paper explores the current literature and highlights the key strategies adopted by different emergency departments to reduce delays and streamline patient flow, including: waiting room nurses; streaming; rapid assessment teams; short stay units and care coordination programmes. Many of these initiatives have proven successful at reducing the number of people re-presenting to the emergency department, addressing time delays and improving the management of existing resources and patient flow. More recent changes include increasing the scope of practice and workload for triage nurses. With the recent introduction of the National Emergency Access Target, which requires that most patients presenting to Australian emergency departments are reviewed and transferred or discharged from the department within 4h, traditional roles of nurses in the emergency department are changing and expanding to meet the needs of modern healthcare systems.

    Increased dietary sodium intake is a modifiable risk factor for cardiovascular disease. The monitoring of population sodium intake is a key part of any salt reduction intervention. However, the extent and methods used for as-sessment of sodium intake in Southeast Asia is currently unclear. This paper provides a narrative synthesis of the best available evidence regarding levels of sodium intake in six Southeast Asian countries: Indonesia, Malaysia, Philippines, Singapore, Thailand, Vietnam, and describes salt reduction measures being undertaken in these countries. Electronic databases were screened to identify relevant articles for inclusion up to 29 February 2012. Reference lists of included studies and conference proceedings were also examined. Local experts and researchers in nutrition and public health were consulted. Quality of studies was assessed using a modified version of the Downs and Black Checklist. Twenty-five studies fulfilled the inclusion criteria and were included in this review. Full texts of 19 studies including government reports were retrieved, with most studies being of good quality. In-sufficient evidence exists regarding salt intakes in Southeast Asia. Dietary data suggest that sodium intake in most SEA countries exceeded the WHO recommendation of 2 g/day. Studies are needed that estimate sodium intake using the gold standard 24-hour urinary sodium excretion. The greatest proportion of dietary sodium came from added salt and sauces. Data on children were limited. The six countries had salt reduction initiatives that differed in specificity and extent, with greater emphasis on consumer education. PMID:24231008

    Despite the benefits derived from the use of assistive technologies (AT), some parts of the world have minimal or no access to AT. In many low-income and middle-income countries (LMIC), only 5–15% of people who require AT have access to them. Rapid demographic changes will exacerbate this situation as populations over 60 years of age, as well as functional limitations among older populations, in LMIC are expected to be higher than in high-income countries in the coming years. Given both these trends, AT are likely to be in high demand and provide many benefits to respond to challenges related to healthy and productive ageing. Multiple databases were searched for English literature. Three groups of keywords were combined: those relating to AT, ageing population and LMIC selected for this study, namely Brazil, Cambodia, Egypt, India, Turkey and Zimbabwe. These countries are expected to see the most rapid growth in the 65 and above population in the coming years. Results indicate that all countries had AT designed for older adults with existing impairment and disability, but had limited AT that are designed to prevent impairment and disability among older adults who do not currently have any disabilities. All countries have ratified the UN Convention on the Rights of Persons with Disabilities. The findings conclude that AT for ageing populations have received some attention in LMIC as attested by the limited literature results. Analysis of review findings indicate the need for a comprehensive, integrated health and social system approach to increase the current availability of AT for ageing populations in LMIC. These would entail, yet not be limited to, work on: (1) promoting initiatives for low-cost AT; (2) awareness raising and capacity building on AT; (3) bridging the gap between AT policy and practice; and (4) fostering targeted research on AT.

    Many older people perceive ageing negatively, describing it in terms of poor or declining health and functioning. These perceptions may be related to older adults' health. The aim of this review was to synthesise existing research on the relationship between older adults' perceptions of ageing and their health and functioning. A systematic search was conducted of five electronic databases (ASSIA, CINAHL, IBSS, MEDLINE and PsycINFO). Citations within identified reports were also searched. Observational studies were included if they included perceptions of ageing and health-related measures involving participants aged 60 years and older. Study selection, data extraction and quality appraisal were conducted using predefined criteria. Twenty-eight reports met the criteria for inclusion. Older adults' perceptions of ageing were assessed with a variety of measures. Perceptions were related to health and functioning across seven health domains: memory and cognitive performance, physical and physiological performance, medical conditions and outcomes, disability, care-seeking, self-rated health, quality of life and death. How ageing is perceived by older adults is related to their health and functioning in multiple domains. However, higher quality and longitudinal studies are needed to further investigate this relationship. PMID:26527056

    Age-related macular degeneration is a complex disease, with both genetic and environmental risk factors interacting in unknown ways. Currently, 52 gene variants within 34 loci have been significantly associated with age-related macular degeneration. Two well-studied major genes are complement factor H (CFH) and age-related maculopathy susceptibility 2 (ARMS2). There exist several commercially available tests that are proposed to stratify patients into high-risk and low-risk groups, as well as predict response to nutritional supplementation. However, at present, the bulk of the available peer-reviewed evidence suggests that genetic testing is more useful as a research tool than for clinical management of patients. PMID:27445455

    Little research can be found describing social aspects of aging with human immunodeficiency virus infection/acquired immunodeficiency syndrome (HIV/AIDS) in Canada specifically, despite an overall increase in an aging population and increased numbers of those aging with HIV/AIDS. A systematic literature review was conducted with a selective focus on social aspects related to older adults who are living with or at risk for contracting HIV/AIDS. The primary themes that emerged in the literature are ageism and stigma, gender, mental health, and social supports. Recommendations for future research regarding prevention and education of risks for older adults and programming suitable for a wide range of audiences are presented. PMID:23941598

    The question of the age of fingermarks is often raised in investigations and trials when suspects admit that they have left their fingermarks at a crime scene but allege that the contact occurred at a different time than the crime and for legal reasons. In the first part of this review article, examples from American appellate court cases will be used to demonstrate that there is a lack of consensus among American courts regarding the admissibility and weight of testimony from expert witnesses who provide opinions about the age of fingermarks. Of course, these issues are not only encountered in America but have also been reported elsewhere, for example in Europe. The disparity in the way fingermark dating cases were managed in these examples is probably due to the fact that no methodology has been validated and accepted by the forensic science community so far. The second part of this review article summarizes the studies reported on fingermark dating in the literature and highlights the fact that most proposed methodologies still suffer from limitations preventing their use in practice. Nevertheless, several approaches based on the evolution of aging parameters detected in fingermark residue over time appear to show promise for the fingermark dating field. Based on these approaches, the definition of a formal methodological framework for fingermark dating cases is proposed in order to produce relevant temporal information. This framework identifies which type of information could and should be obtained about fingermark aging and what developments are still required to scientifically address dating issues.

    One in six children entering school experiences developmental delay. Maternal mental health represents one of the earliest, modifiable influences in a child's life. The objective of the review was to evaluate the association between maternal mental health and school-age child development, and we hypothesized there would be a negative association. Five databases were searched (Embase, CINAHL, Eric, PsycInfo, Medline). Key journals and reference lists were hand-searched. Two reviewers assessed studies based on inclusion criteria: (1) the exposure was any form of maternal mental health occurring during pregnancy or postpartum periods; (2) the outcome was child development (>48 months to 8 years); (3) the study recruited participants from developed countries; and (4) publication was in English between January, 1990 and December, 2012. Disagreements were resolved by consensus. Study quality was assessed by two reviewers using the Scottish Intercollegiate Guideline Network and disagreements were resolved by consensus. Data extraction was conducted by one reviewer using standardized forms. Maternal mental health problems in pregnancy and/or the postpartum period increased the likelihood that school-age children experienced suboptimal global, behavioral, cognitive, and socio-emotional development. The findings highlight the need for maternal mental health assessment during the prenatal, postnatal, and early childhood periods. PMID:24352625

    e-Health interventions could contribute to healthy aging (HA) but their effectiveness has not been synthesised. This study aims to systematically review the effectiveness of e-health interventions for supporting HA. We will perform standardized searches to identify experimental and quasi-experimental studies evaluating the effectiveness of e-health interventions for HA. Outcomes of interest are: wellbeing, quality of life, activities of daily living, leisure activities, knowledge, evaluation of care, social support, skill acquisition and healthy behaviours. We will also consider adverse effects such as social isolation, anxiety, and burden on informal caregivers. Two reviewers will independently assess studies for inclusion and extract data using a standardised tool. We will calculate effect sizes related to e-health interventions. If not possible, we will present the findings in a narrative form. This systematic review will provide unique knowledge on the effectiveness of e-health interventions for supporting HA.

    Abstract We analyzed the association of age at antiretroviral therapy (ART) initiation with CD4+ T cell count recovery, death, and loss to follow-up (LTFU) among HIV-infected adults in Zambia. We compared baseline characteristics of patients by sex and age at ART initiation [categorized as 16–29 years, 30–39 years, 40–49 years, 50–59 years, and 60 years and older]. We used the medication possession ratio to assess adherence and analysis of covariance to measure the adjusted change in CD4+ T cell count during ART. Using Cox proportional hazard regression, we examined the association of age with death and LTFU. In a secondary analysis, we repeated models with age as a continuous variable. Among 92,130 HIV-infected adults who initiated ART, the median age was 34 years and 6,281 (6.8%) were aged ≥50 years. Compared with 16–29 year olds, 40–49 year olds (–46 cells/mm3), 50–59 year olds (–53 cells/mm3), and 60+ year olds (–60 cells/mm3) had reduced CD4+ T cell gains during ART. The adjusted hazard ratio (AHR) for death was increased for individuals aged ≥40 years (AHR 1.25 for 40–49 year olds, 1.56 for 50–59 year olds, and 2.97 for 60+ year olds). Adherence and retention in care were poorest among 16–29 year olds but similar in other groups. As a continuous variable, a 5-year increase in age predicted reduced CD4+ T cell count recovery and increased risk of death. Increased age at ART initiation was associated with poorer clinical outcomes, while age <30 years was associated with a higher likelihood of being lost to follow-up. HIV treatment guidelines should consider age-specific recommendations. PMID:24998881

  10. Active Aging for Individuals with Parkinson's Disease: Definitions, Literature Review, and Models

    PubMed Central

    Lökk, Johan

    2014-01-01

    Active aging has been emerged to optimize different aspects of health opportunities during the aging process in order to enhance quality of life. Yet, most of the efforts are on normal aging and less attention has been paid for the elderly suffering from a chronic illness such as Parkinson's disease (PD). The aim of this review was to investigate how the concept of “active aging” fit for the elderly with PD and to propose a new model for them using the recent improvements in caring models and management approaches. For this purpose, biomedical databases have been assessed using relevant keywords to find out appropriate articles. Movement problems of PD affect physical activity, psychiatric symptoms lessen social communication, and cognitive impairment could worsen mental well-being in elderly with PD, all of which could lead to earlier retirement and poorer quality of life compared with healthy elderly. Based on the multisystematic nature of PD, a new “Active Aging Model for Parkinson's Disease” is proposed consisting of self-care, multidisciplinary and interdisciplinary care, palliative care, patient-centered care, and personalized care. These strategies could potentially help the individuals with PD to have a better management approach for their condition towards the concept of active aging. PMID:25225618

  11. Ageism and age discrimination in health care: Fact or fiction? A narrative review of the literature.

    PubMed

    Kydd, Angela; Fleming, Anne

    2015-08-01

    Ageism and age discrimination are terms used in best practice statements and in the literature to define negative attitudes towards older people and towards people because of their age (whether old or young). However, 'old age' is a nebulous concept with definitions ranging from the over 50s to the over 85s. In seeking to explore ageism and age discrimination within health care, this paper discusses the concept of 'old' and discusses the findings of a narrative review of the literature on these two concepts. Results show that negative attitudes have been perceived by users of health care services, but the reasons are not clear. Such attitudes are usually reported in acute health care settings, where targets and quick turnover are encouraged. Thus people, usually those with complex needs, who require longer periods of recuperation and rehabilitation following an episode of ill health, are troublesome to staff working in a system geared up for early discharges. This type of service user is usually over the age of 85. Recommendations from this paper include the need for acute frailty units, with well trained staff, where frail older people can be comprehensively assessed, receive timely and targeted care, followed by a supported discharge.

    Vaccination rates for human papillomavirus (HPV) have remained disappointingly low. It is critical to identify methods to increase on-time vaccine series completion rates (before 13 or 15years). To determine whether younger age (9 to 10years of age) at HPV vaccine series initiation was associated with improved on-time completion rates compared to initiation at 11 to 12years, we examined the prevalence of on-time HPV vaccine series completion rates from August 2006 through December 2012 in a large, population-based cohort of children and adolescents (aged 9.5 to 27years) residing in Olmsted County, MN on December 31, 2012 (n=36,223). We compared age at vaccine initiation between individuals who successfully completed both 2 and 3 doses of the vaccination series on-time (before age 13.5 or 15.0years) using multivariate logistic regression. On-time completion of both 2 and 3 doses of the vaccine series by age 13.5 or 15.0years was significantly associated with initiation at 9 to 10years as compared to 11 to 12years after adjusting for sex, race, insurance status, frequent health care visits, and year of first vaccination (all p<.01). Interventions focused on beginning the vaccination series at 9 to 10years of age may result in higher rates of timely series completion. PMID:26930513

  13. The evolution of aging phenotypes in snakes: a review and synthesis with new data

    PubMed Central

    2008-01-01

    Reptiles are underutilized vertebrate models in the study of the evolution and persistence of senescence. Their unique physiology, indeterminate growth, and increasing fecundity across the adult female lifespan motivate the study of how physiology at the mechanistic level, life history at the organismal level, and natural selection at the evolutionary timescale define lifespan in this diverse taxonomic group. Reviewed here are, first, comparative results of cellular metabolic studies conducted across a range of colubrid snake species with variable lifespan. New results on the efficiency of DNA repair in these species are synthesized with the cellular studies. Second, detailed studies of the ecology, life history, and cellular physiology are reviewed for one colubrid species with either short or long lifespan (Thamnophis elegans). New results on the rate of telomere shortening with age in this species are synthesized with previous research. The comparative and intraspecific studies both yield results that species with longer lifespans have underlying cellular physiologies support the free-radical/repair mechanistic hypothesis for aging. As well, both underscore the importance of mortality environment for the evolution of aging rate. PMID:19424866

    This paper is a summary of findings of adult age-related craniofacial morphological changes. Our aims are two-fold: (1) through a review of the literature we address the factors influencing craniofacial aging, and (2) the general ways in which a head and face age in adulthood. We present findings on environmental and innate influences on face aging, facial soft tissue age changes, and bony changes in the craniofacial and dentoalveolar skeleton. We then briefly address the relevance of this information to forensic science research and applications, such as the development of computer facial age-progression and face recognition technologies, and contributions to forensic sketch artistry.

    2014-06-01

    Electrodeposited Co and Mn spinel phase oxides for application as coatings for metallic interconnectors in Solid Oxide Fuel Cells were prepared. The study aims at understanding the initial stages of transformation of the metallic layers into the spinel phase. Co and Mn metallic layers were sequentially deposited over AISI 430 stainless steel substrate from acidic sulfate solutions and annealed in oxidizing and inert atmospheres between 600 °C and 800 °C. The coatings obtained showed a thickness above 20 μm. After 1 h of isothermal aging the coatings were composed of layers of un-reacted metallic elements and Mn based oxides. The spinel phase was studied by XRD and revealed Mn based tetragonal structure Mn3O4 with Co in solid solution and a non-determined Co/Mn ratio. According to EDS measurements this ratio should vary with depth. Full conversion was not obtained at these time frames with the presence other Mn oxides (MnO and Mn2O3). In inert atmosphere, the allotropic Mn transformation from α to β phase was detected. No outward diffusion of Cr was detected, due to the short exposure times.

    2007-01-01

    Background and aim To update our 1996 review on the incidence of subarachnoid haemorrhage (SAH) and assess the relation of incidence with region, age, gender and time period. Methods We searched for studies on the incidence of SAH published until October 2005. The overall incidences with corresponding 95% confidence intervals were calculated. We determined the relationship between the incidence of SAH and determinants by means of univariate Poisson regression. Results We included 51 studies (33 new), describing 58 study populations in 21 countries, observing 45 821 896 person‐years. Incidences per 100 000 person‐years were 22.7 (95% CI 21.9 to 23.5) in Japan, 19.7 (18.1 to 21.3) in Finland, 4.2 (3.1 to 5.7) in South and Central America, and 9.1 (8.8 to 9.5) in the other regions. With age category 45–55 years as the reference, incidence ratios increased from 0.10 (0.08 to 0.14) for age groups younger than 25 years to 1.61 (1.24 to 2.07) for age groups older than 85 years. The incidence in women was 1.24 (1.09 to 1.42) times higher than in men; this gender difference started at age 55 years and increased thereafter. Between 1950 and 2005, the incidence decreased by 0.6% (1.3% decrease to 0.1% increase) per year. Conclusions The overall incidence of SAH is approximately 9 per 100 000 person‐years. Rates are higher in Japan and Finland and increase with age. The preponderance of women starts only in the sixth decade. The decline in incidence of SAH over the past 45 years is relatively moderate compared with that for stroke in general. PMID:17470467

    Age-related face recognition deficits are characterized by high false alarms to unfamiliar faces, are not as pronounced for other complex stimuli, and are only partially related to general age-related impairments in cognition. This paper reviews some of the underlying processes likely to be implicated in theses deficits by focusing on areas where contradictions abound as a means to highlight avenues for future research. Research pertaining to the three following hypotheses is presented: (i) perceptual deterioration, (ii) encoding of configural information, and (iii) difficulties in recollecting contextual information. The evidence surveyed provides support for the idea that all three factors are likely to contribute, under certain conditions, to the deficits in face recognition seen in older adults. We discuss how these different factors might interact in the context of a generic framework of the different stages implicated in face recognition. Several suggestions for future investigations are outlined. PMID:26347670

    According to the dual-process theoretical perspective adopted in the presented research, the efficiency of deliberative processes in decision making declines with age, but experiential processes are relatively well-preserved. The age-related differences in deliberative and experiential processes in risky decision-making were examined in this research by applying the Balloon Analog Risk Task (BART). We analyzed the influence of age on risk acceptance and decision-making performance in two age groups of female participants (younger adults, n = 81; older adults, n = 76), with additional experimental manipulation of initial risk perception. We predicted and confirmed that aging significantly worsens performance on the behavioral BART measures due to age-related decline in deliberative processes. Older participants were found to exhibit significantly higher risk aversion and lower BART performance, and the effect of age was mediated by cognitive (processing speed) and motivational (need for cognitive closure) mechanisms. Moreover, older adults adapt to the initial failure (vs. success) similarly, as younger adults due to preserved efficiency of experiential processes. These results suggest future directions for minimizing negative effects of aging in risky decision-making and indicate compensatory processes, which are preserved during aging. PMID:27199877
