This study examined the prevalence of loneliness among the oldest old within a 10-year period and studied the influence of various sociodemographic, social and health characteristics on loneliness. The study used population-based data from the Umeå85+/GErontological Regional DAtabase-study (GERDA) for the years 2000-2002, 2005-2007 and 2010-2012 including 85-year-old, 90-year-old and ⩾95-year-old participants. A final sample of 304 participants in 2000-2002, 329 participants in 2005-2007 and 401 participants in 2010-2012 was included in the analyses. Although the level of loneliness was already high in 2000-2002 (49.3% reported frequent loneliness), the results showed limited changes in loneliness during the 10-year study period. Loneliness was closely related to living alone, depressive symptoms and living in institutional settings. Although societal changes such as solitary living and growing urbanization suggest a changing trend in loneliness, we found that the prevalence of loneliness was relatively stable in this study. Nevertheless, loneliness is common among the oldest old and a focus on social issues related to living arrangements and on depressive symptoms is important in understanding loneliness.

In this study, neutron reflectometry (NR) was used to examine various live cells' adhesion to quartz substrates under different environmental conditions, including flow stress. To the best of our knowledge, these measurements represent the first successful visualization and quantization of the interface between live cells and a substrate with sub-nanometer resolution. In our first experiments, we examined live mouse fibroblast cells as opposed to past experiments using supported lipids, proteins, or peptide layers with no associated cells. We continued the NR studies of cell adhesion by investigating endothelial monolayers and glioblastoma cells under dynamic flow conditions. We demonstrated that neutronmore » reflectometry is a powerful tool to study the strength of cellular layer adhesion in living tissues, which is a key factor in understanding the physiology of cell interactions and conditions leading to abnormal or disease circumstances. Continuative measurements, such as investigating changes in tumor cell — surface contact of various glioblastomas, could impact advancements in tumor treatments. In principle, this can help us to identify changes that correlate with tumor invasiveness. Pursuit of these studies can have significant medical impact on the understanding of complex biological problems and their effective treatment, e.g. for the development of targeted anti-invasive therapies.« less

This study analyzed the dietary pattern of Southeast Asian workers (Vietnamese, Thais, Cambodians and Myanmar) living in South Korea in order to recognize the dietary changes after they moved to South Korea. Questionnaires were completed by 251 Southeast Asian workers living in South Korea. Using a self-administered questionnaire, we assessed the diets before and after living in the hometown and in South Korea. Significant changes observed in the Southeast Asian workers were decreased in consumption frequency of fresh fruits, cooked vegetables, rice noodles, green tea and glutinous rice, and increase in consumption of Kimchi, seaweed, milk, coffee and pizza. These changes were attributed to rapid dietary acculturation. The frequencies of eating homemade food were significantly decreased after they came to Korea except for Thais. Thais showed the highest frequencies of eating homemade food daily among others. 28.2% of respondents said their health condition had deteriorated after living in South Korea due to difficulties to adapt Korean food, increased frequencies of eating instant food, and lacking exercises. By providing understanding of the dietary patterns of Southeast Asian workers, these results can be used for preliminary data to develop a program for their Korean food adaptation.

There have been fundamental shifts in the attitude towards, access to and nature of long term care in high income countries. The proportion and profile of the older population living in such settings varies according to social, cultural, and economic characteristics as well as governmental policies. Changes in the profiles of people in different settings are important for policy makers and care providers. Although details will differ, how change occurs across time is important to all, including lower and middle income countries developing policies themselves. Here change is examined across two decades in England. Using the two Cognitive Function and Ageing Studies (CFAS I: 77% response, CFAS II: 56% response), two population based studies of older people carried out in the same areas conducted two decades apart, the study diagnosis of dementia using the Automated Geriatric Examination for Computer Assisted Taxonomy, health and wellbeing were examined, focusing on long term care. The proportion of individuals with three or more health conditions increased for everyone living in long term care between CFAS I (47.6%, 95% CI: 42.3-53.1) and CFAS II (62.7%, 95% CI: 54.8-70.0) and was consistently higher in those without dementia compared to those with dementia in both studies. Functional impairment measured by activities of daily living increased in assisted living facilities from 48% (95% CI: 44%-52%) to 67% (95% CI: 62%-71%). Health profiles of residents in long term care have changed dramatically over time. Dementia prevalence and reporting multiple health conditions have increased. Receiving care in the community puts pressure on unpaid carers and formal services; these results have implications for policies about supporting people at home as well as for service provision within long term care including quality of care, health management, cost, and the development of a skilled, caring, and informed workforce.

The prevalence and severity of dysphagia in people treated non-surgically for primary head and neck cancer (HNC) is well documented. However, few studies have looked beyond the physiological impairment to explore the lived experience of dysphagia in the post-treatment period of HNC. The current study adopted a person-centred, qualitative approach to describe the experiences of people living with dysphagia in the months and years following non-surgical treatment for HNC. Using maximum variation sampling, 24 participants who had undergone radiotherapy treatment for HNC were recruited. Individual interviews were conducted to explore the impact of dysphagia on participants' everyday lives. The themes identified included: (1) physical changes related to swallowing; (2) emotions evoked by living with dysphagia; (3) altered perceptions and changes in appreciation of food; and (4) personal and lifestyle impacts. The data revealed the breadth and significance of the impact of dysphagia on the lives of people treated curatively for HNC. Assessment and management in the post-treatment period must be sufficiently holistic to address both the changing physical states and the psychosocial needs of people with dysphagia following HNC. Rehabilitation services which focus only on impairment-based management will fail to fully meet the support needs of this clinical population.

Examining live cell cultures during apoptosis by digital holographic phase imaging and Raman spectroscopy

Khmaladze, Alexander

2017-11-01

Cellular apoptosis is a unique, organized series of events, leading to programmed cell death. In this work, we present a combined digital holography/Raman spectroscopy technique to study live cell cultures during apoptosis. Digital holographic microscopy measurements of live cell cultures yield information about cell shape and volume, changes to which are indicative of alterations in cell cycle and initiation of cell death mechanisms. Raman spectroscopic measurements provide complementary information about cells, such as protein, lipid and nucleic acid content, and the spectral signatures associated with structural changes in molecules. Our work indicates that the chemical changes in proteins, which were detected by Raman measurements, preceded morphological changes, which were seen with digital holographic microscopy.

Survivors who lost their homes in the Great East Japan Earthquake and Tsunami were forced to live in difficult conditions in temporary housing several months after the disaster. Body weights of survivors living in temporary housing for a long period might increase due to changes in their life style and psychosocial state during the medium-term and long-term recovery phases. The aim of this study was to determine whether there were differences between body weight changes of people living in temporary housing and those not living in temporary housing in a tsunami-stricken area during the medium-term and long-term recovery phases. Health check-ups were performed about 7 months after the disaster (in 2011) and about 18 months after the disaster (in 2012) for people living in a tsunami-stricken area (n = 6,601, mean age = 62.3 y). We compared the changes in body weight in people living in temporary housing (TH group, n = 2,002) and those not living in temporary housing (NTH group, n = 4,599) using a multiple linear regression model. While there was no significant difference between body weights in the TH and NTH groups in the 2011 survey, there was a significant difference between the mean changes in body weight in both sexes. We found that the changes in body weight were significantly greater in the TH group than in the NTH group in both sexes. The partial regression coefficients of mean change in body weight were +0.52 kg (P-value < 0.001) in males in the TH group and +0.56 kg (P-value < 0.001) in females in the TH group (reference: NTH group). Analysis after adjustment for life style, psychosocial factors and cardiovascular risk factors found that people living in temporary housing in the tsunami- stricken area had a significant increase in body weight.

The Facade of Stability in Assisted Living

PubMed Central

2014-01-01

Objectives. The study sought to identify the varied types of change arising from internal and external influences in assisted living (AL) settings, expanding upon the literature’s limited focus on resident decline and staff turnover and clarifying the importance of changes to life and work there. Method. This analysis employed qualitative interviews and observations from 4 studies involving 17 ALs to identify elements of change largely absent from the literature. Case material identified by the research team members relating to persons, groups, and settings exemplifying typical changes, as well as variations across settings, are presented. Results. Multiple domains of AL change were identified, to include those in: (a) the external economic or competitive environments; (b) ownership, management, or key personnel; and (c) physical health or cognition of the aggregate resident population. In many cases, the changes influenced residents’ satisfaction and perceived fit with the AL environment. Discussion. Change of many types is a regular feature of AL; many changes alter routines or daily life; raise concerns of staff, residents, or families; or modify perceptions of residential normalcy. Environmental gerontology should more often extend the environment to include the social and interpersonal characteristics of collective living sites for elders. PMID:24642968

Both childhood maltreatment and frequent childhood residence changes are associated with poor behavioral outcomes including drug use and delinquency. It is not clear whether a higher number of residences results in poorer outcomes for maltreated adolescents compared to adolescents living in the same community but without child welfare-documented maltreatment. Our study of child welfare-affiliated maltreated youth (n=216) and comparison youth (n=128) from the same community (age M = 18.21, SD = 1.42) examined: 1. whether child/caregiver characteristics and maltreatment status were associated with lifetime number of residences and 2. whether child/caregiver characteristics, residences, and maltreatment status were associated with delinquency and marijuana use. The outcomes of this study, number of residences, delinquency, and marijuana use, were all skewed, and consequently negative binomial regressions were used. Maltreatment status, ever living with a non-parent caregiver, and being older are associated with more residence changes during childhood. More residences and male sex are associated with person offense delinquency and marijuana use. In lower income neighborhoods, such as where the adolescents in this study lived, residence changes are not unusual, but in this study maltreated youth moved more often than youth from the same community. It is important to help caregivers who live in disadvantaged neighborhoods, especially families with child welfare involvement, understand the behavioral consequences of residence changes and provide support for stable long-term housing.

OBJECTIVE: To compare assisted living residents and nursing home residents on outcome trajectories for three outcomes: ability to perform activities of daily living (ADLs), psychological well-being, and pain and discomfort. DATA SOURCES/STUDY SETTING: A representative sample of one-third of the census from 38 participating assisted living facilities (N = 605) and two-fifths of the census from 31 participating nursing facilities (N = 610). STUDY DESIGN: A longitudinal design using hierarchical linear models to examine how setting (being in an assisted living setting or in a nursing home) affected growth trajectories for each outcome studied when adjusting for other resident characteristics. DATA COLLECTION: Residents or their proxies were interviewed and chart reviews done at baseline, six months, and one year. All baseline data were collected between August 1995 and May 1996. PRINCIPAL FINDINGS: We found differences in case mix between assisted living and nursing facility residents but no differences in outcome trajectories for ADLs, psychological well-being, and pain and discomfort. For ADLs and pain and discomfort on average, residents in both settings experienced change over the study period. For psychological well-being, residents experienced no change on average. CONCLUSIONS: The lack of difference in growth trajectories for ADLs, pain and discomfort, and psychological well-being between the two settings was noteworthy. PMID:11324746

Acute effects of firefighting on cardiac performance.

This study examined standard echocardiographic measures of cardiac size and performance in response to a 3-h firefighting training exercise. Forty experienced male personnel completed a standardized 3 h live firefighting exercise. Before and after the firefighting activities, participants were weighed, height, heart rate, blood pressure and blood samples were obtained, and echocardiographic measurements were made. Firefighting produced significant decreases in left ventricular diastolic dimension, stroke volume, fractional shortening, and mitral E velocity, tachycardia, a rise in core temperature, and a reduction in calculated plasma volume. On tissue Doppler imaging, there were no changes in systolic contractile function, but a decreased lateral wall diastolic velocity was observed. These findings show that 3 h of live firefighting produced cardiac changes consistent with cardiac fatigue, coupled with a decrease in systemic arterial compliance. These data show that live firefighting produces significant cardiovascular changes and future work is needed to evaluate if these changes are related to the increase in cardiovascular risk during live firefighting.

Identifying drivers of biodiversity change from fossil long-lived lakes: lessons for risk and resilience of todays long-lived lake biota.

NASA Astrophysics Data System (ADS)

2015-04-01

Several fossil long-lived lake systems exist that have a very good spatiotemporal geological and faunal record enabling us to study timeseries of biodiversity change. These complexes, such as the Miocene Pannonian and Quaternary Pontocaspian systems of Europe, Quaternary Lake Biwa in Japan and the Miocene Pebas System in South America enable us to assess the impact of environmental stability and pertubation on component processes of turnover, e.g. migration, speciation and extinction/ extirpation. Also, the temporal dimensions of such processes can be clarified and compared to the nature and rates of current turnover in long-lived lake systems. Our studies suggest that we are currently witnessing dramatic biodiversity loss caused mostly by habitat degradation and destruction in smaller lakes and invasives in larger lakes that may exceed the potential of endemic lake biota to recover. Long-live lakes should serve as an excellent illustration of the magnitude of the current anthropogenic-induced biodiversity crisis.

Head and neck cancer (HNC) survivors may experience functional changes to their voice, speech and hearing following curative chemoradiotherapy. However, few studies have explored the impact of living with such changes from the perspective of the HNC survivor and their carer. The current study employed a person-centred approach to explore the lived experience of communication changes following chemoradiotherapy treatment for HNC from the perspective of survivors and carers. Participants included 14 survivors with non-glottic HNC and nine carers. All participants took part in in-depth interviews where they were encouraged to describe their experiences of living with and adjusting to communication changes following treatment. Interviews were analysed as a single data set. Four themes emerged including: (1) impairments in communication sub-systems; (2) the challenges of communicating in everyday life; (3) broad ranging effects of communication changes; and (4) adaptations as a result of communication changes. These data confirm that communication changes following chemoradiotherapy have potentially negative psychosocial impacts on both the HNC survivor and their carer. Clinicians should consider the impact of communication changes on the life of the HNC survivor and their carer and provide adequate and timely education and management to address the needs of this population.

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

Lang, Jessica; Schmitz, Bernhard

2016-11-01

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

A phenomenological study of living with a partner affected with dementia.

Caring for people affected by dementia is a collective effort that involves public health, primary care, and informal care. The third mainly comprises the efforts of spouses. This study aimed to describe spouses' experiences of living with a partner affected with dementia. The study has a descriptive phenomenological approach based on a reflective life-world perspective. Seven in-depth interviews were conducted with spouses of persons affected with dementia. The interviews were audiotaped and analysed using the procedures described by Giorgi (2009) . The essence of living with a partner affected by dementia formed a comprehensive theme: from togetherness to loneliness, which along with three descriptive categories-changes in their partner's behaviour, changes in everyday life, and a changed future-describes the phenomenon. The theme 'From togetherness to loneliness' reflects the spouses' descriptions of their life-world. Daily life changed gradually in line with their partners' personality, and their role became that of a care provider rather than a spouse. Information and knowledge about dementia should be provided at an early stage. Health care has a major responsibility to meet their needs, thus ensuring that all parties are satisfied.

In this study the authors assessed a Good Lives model (GLM) approach to sex offender treatment and compare it to a standard Relapse Prevention program. The comparisons examined (a) attrition rates, (b) treatment change in areas targeted in treatment and achievement of a posttreatment treated profile, and (c) views of offenders and facilitators. There were no differences in the attrition rates or the rates of treatment change between the two programs, indicating that they were equally effective at retaining participants and achieving change on areas targeted within treatment. Both facilitators and program participants reported the Good Lives approach module's impact in a positive, future-focused manner. In contrast, those who attended the Relapse Prevention module did not report their perceptions and motivations in a manner that was focused on the positives in their future as frequently as those who attended the module with the Good Lives model approach.

Imaging Live Drosophila Brain with Two-Photon Fluorescence Microscopy

NASA Astrophysics Data System (ADS)

Ahmed, Syeed Ehsan

Two-photon fluorescence microscopy is an imaging technique which delivers distinct benefits for in vivo cellular and molecular imaging. Cyclic adenosine monophosphate (cAMP), a second messenger molecule, is responsible for triggering many physiological changes in neural system. However, the mechanism by which this molecule regulates responses in neuron cells is not yet clearly understood. When cAMP binds to a target protein, it changes the structure of that protein. Therefore, studying this molecular structure change with fluorescence resonance energy transfer (FRET) imaging can shed light on the cAMP functioning mechanism. FRET is a non-radiative dipole-dipole coupling which is sensitive to small distance change in nanometer scale. In this study we have investigated the effect of dopamine in cAMP dynamics in vivo. In our study two-photon fluorescence microscope was used for imaging mushroom bodies inside live Drosophila melanogaster brain and we developed a method for studying the change in cyclic AMP level.

Background There have been fundamental shifts in the attitude towards, access to and nature of long term care in high income countries. The proportion and profile of the older population living in such settings varies according to social, cultural, and economic characteristics as well as governmental policies. Changes in the profiles of people in different settings are important for policy makers and care providers. Although details will differ, how change occurs across time is important to all, including lower and middle income countries developing policies themselves. Here change is examined across two decades in England.

Differentiation of embryonic stem cells is accompanied by changes of gene expression and chromatin and chromosome dynamics. One of the most impressive examples for these changes is inactivation of one of the two X chromosomes occurring upon differentiation of mouse female embryonic stem cells. With a few exceptions, these events have been mainly studied in fixed cells. In order to better understand the dynamics, kinetics, and order of events during differentiation, one needs to employ live-cell imaging techniques. Here, we describe a combination of live-cell imaging with techniques that can be used in fixed cells (e.g., RNA FISH) to correlate locus dynamics or subnuclear localization with, e.g., gene expression. To study locus dynamics in female ES cells, we generated cell lines containing TetO arrays in the X-inactivation center, the locus on the X chromosome regulating X-inactivation, which can be visualized upon expression of TetR fused to fluorescent proteins. We will use this system to elaborate on how to generate ES cell lines for live-cell imaging of locus dynamics, how to culture ES cells prior to live-cell imaging, and to describe typical live-cell imaging conditions for ES cells using different microscopes. Furthermore, we will explain how RNA, DNA FISH, or immunofluorescence can be applied following live-cell imaging to correlate gene expression with locus dynamics.

The organization of chromatin is a regulator of molecular processes including transcription, replication, and DNA repair. The structures within chromatin that regulate these processes span from the nucleosomal (10-nm) to the chromosomal (>200-nm) levels, with little known about the dynamics of chromatin structure between these scales due to a lack of quantitative imaging technique in live cells. Previous work using partial-wave spectroscopic (PWS) microscopy, a quantitative imaging technique with sensitivity to macromolecular organization between 20 and 200 nm, has shown that transformation of chromatin at these length scales is a fundamental event during carcinogenesis. As the dynamics of chromatin likely play a critical regulatory role in cellular function, it is critical to develop live-cell imaging techniques that can probe the real-time temporal behavior of the chromatin nanoarchitecture. Therefore, we developed a live-cell PWS technique that allows high-throughput, label-free study of the causal relationship between nanoscale organization and molecular function in real time. In this work, we use live-cell PWS to study the change in chromatin structure due to DNA damage and expand on the link between metabolic function and the structure of higher-order chromatin. In particular, we studied the temporal changes to chromatin during UV light exposure, show that live-cell DNA-binding dyes induce damage to chromatin within seconds, and demonstrate a direct link between higher-order chromatin structure and mitochondrial membrane potential. Because biological function is tightly paired with structure, live-cell PWS is a powerful tool to study the nanoscale structure–function relationship in live cells. PMID:27702891

The objective of this study was to assess the burdens of anticholinergic and sedative drugs in community-living individuals of 85 years of age or older. The Tokyo Oldest Old survey on Total Health (TOOTH) is a cohort study designed to assess the physical, mental, and oral health of the community-living oldest old. We investigated the relationships between the anticholinergic/sedative burden and physical/cognitive outcomes. The drug burden was assessed by the Drug Burden Index (DBI). Relationships between the DBI score and the physical/cognitive outcomes were evaluated by multivariate regression. The age-related changes (baseline to 3-year follow-up) of these outcomes were also investigated. At baseline, the data of 306 subjects were subjected to a cross-sectional analysis. The Instrumental Activities of Daily Living and Mini Mental State Examination scores were found to be significantly associated with the DBI score. After 3 years, the Activities of Daily Living score was significantly associated with the DBI score in 176 subjects. Changes in these outcome measures were small during the 3-year follow-up period and were not associated with the DBI scores at baseline. DBI in the community-living oldest old were evaluated. Our findings suggest that anticholinergic and sedative drugs may influence the physical and cognitive function in the oldest old. Additional studies should be performed to investigate the relationships between the change of the physical/cognitive functions and the DBI score over a long-term observation period.

Policies of deterrence, including the use of detention and temporary visas, have been widely implemented to dissuade asylum seekers from seeking protection in Western countries. The present study examined the impact of visa status change on the mental health of 97 Mandaean refugees resettled in Australia. At the time of the first survey (2004), 68 (70%) participants held temporary protection visas (TPVs) and 29 (30%) held permanent residency (PR) status, whereas by the second survey (2007), 97 (100%) participants held PR status. We tested a meditational model to determine whether the relationship between change in visa status and change in psychological symptoms was mediated by change in living difficulties associated with the visa categories. The conversion of visa status from TPV to PR status was associated with significant improvements in PTSD and depression symptoms, and increases in mental health-related quality of life (MHR-QOL). The relationship between change in visa status and reduced PTSD and depression symptoms was mediated by reductions in living difficulties. In contrast, the relationship between change in visa status and increased MHR-QOL was not mediated by changes in living difficulties. These results suggest that restriction of rights and access to services related to visa status negatively affect the mental health of refugees. Implications for government policies regarding refugees are discussed. Copyright © 2010. Published by Elsevier Ireland Ltd.

Results of a field test and follow-up study of a restorative care training program.

To implement restorative care in assisted living facilities, staff and administrators need to understand the philosophy and learn methods to help residents maintain optimal function. In this study, researchers investigated the use of a Web-based training program to improve the restorative care knowledge, attitudes, and practices of assisted living administrators and staff. The study design was one group repeated measure to consider the impact of the training program on participant's knowledge of restorative care and restorative care techniques, attitudes toward restorative care, and self-reported practices. Participants included 266 administrators and 203 direct care staff from assisted living facilities in eight states. Measurements were done at baseline (pretest), following the instruction (posttest), and one month later (follow-up). Researchers found that participants (n=469) significantly improved their scores from pre- to posttest. In a follow-up study (n=244), over half of participants reported making changes at their facility as a result of the restorative care training. Most of the changes are related to care practices, such as an emphasis on encouraging, motivating, and offering positive feedback to residents. Researchers concluded that there is a need for restorative care training for both administrators and staff of assisted living facilities. The study also demonstrates that a brief training session (2h or less) can bring about significant change in the learner's knowledge of facts, attitudes, and practices. It demonstrates that much of that change continues for at least 1 month after the training. It also demonstrates the loss of knowledge and points out the need for training to be followed up with continuing education and administrator encouragement. Furthermore, this study demonstrates that the Web is a feasible method of delivering restorative care training to assisted living facility administrators and staff. Copyright © 2012 Elsevier Ltd.

Despite substantial increases in improving the translation of health promotion research into practice, community initiatives still struggle with maintaining changes once grant funding has ended. Researchers, funders, and community practitioners are interested in practices that maintain and sustain their efforts. This qualitative study conducted a content analysis of evaluation findings from Active Living by Design (ALbD) to identify activities that community coalitions implemented to maintain their initiative and secure ongoing influence in communities. Investigators analyzed data from interviews, focus groups, and the Progress Reporting System to identify sustainability approaches clustering into five areas: partnership expansion, sustainable funding, permanent advisory committees, policy change, and institution/organization change. Partnership expansion occurred across sectors and disciplines and into broader geographic areas. Additional funding extended beyond grants to earned income streams and dedicated tax revenues. Permanent advisory committees were established to inform decision makers about a range of active living impacts. Policy changes in zoning and comprehensive plans ensured maintenance of health-promoting built environments. Sustainability through institution/organization changes led to allocation of dedicated staff and incorporation of active living values into agency missions. Active Living by Design partnerships defined and messaged their projects to align with policymakers' interests and broad partnership audiences. They found innovative supporters and adapted their original vision to include quality of life, nonmotorized transport, and other complementary efforts that expanded their reach and influence. These sustainability strategies altered awareness within communities, changed community decision-making processes, and created policy changes that have the potential to maintain environments that promote physical activity for years to come.

Living with coeliac disease: a grounded theory study.

PubMed

Rose, C; Howard, R

2014-02-01

Coeliac disease can be controlled only through adherence to a gluten-free diet. This diet is highly restrictive and can be challenging to maintain. It has been linked with elevated levels of psychological distress, including depression, anxiety and social phobia. Narratives on living with coeliac disease were written by 130 adult members of Coeliac UK (mean age 52.7 years; mean time since diagnosis 10.2 years; 67% sample female; 28% male). Qualitative analysis using grounded theory methods identified five key categories: living with widespread ignorance; social invisibility; creating a coeliac community; a changed identity; grief - and accepting the trade-off. A psychosocial model of living with coeliac disease was constructed from the findings, the central category of which was the changed identity of those diagnosed with the condition. Grief was experienced in relation to a loss of the former diet, changed personal and social identities, loss of social confidence and loss of social activities. Grief was generally mitigated over time as adjustments were made to changes in identity and lifestyle. Creating (or becoming part of) a coeliac community was a strategy enabling those with coeliac disease to re-establish their identities and increase social recognition and acceptance of the condition. Gluten-free living entails a substantial restriction of food choice. The losses and changes entailed impact on the personal and social identities of those living with coeliac disease, and on the behaviour of others towards them. Psychosocial interventions focussed on facilitating coping and adjustment may benefit those experiencing difficulties. © 2013 The Authors Journal of Human Nutrition and Dietetics © 2013 The British Dietetic Association Ltd.

Long-term Changes in Habitat Provision by a Temperate Benthic Bioconstructor Threatened by Extreme Events

NASA Astrophysics Data System (ADS)

Cocito, S.; Lombardi, C.

2016-02-01

In a wide range of temperate environmental settings, long-lived, carbonate benthic organisms provide the framework of biogenic constructions, which create and maintain habitats and ecological niches for many species. These physical structures provide living space which progressively increases as framework grows. In temperate waters, bryozoans can have reef-constructing roles, and can substitute for corals in abundance and structure. As all bioconstructional species, they are seriously threaten by climate changes and its consequences such as thermal anomalies. The present study provides an assessment of changes in habitat provision by a reef-forming bryozoan dominating sub-tidal rocky reefs in the Ligurian Sea (NW Mediterranean) through 9-year time. Large ellipsoidal foliaceous colonies of Pentapora fascialis were monitored in 12 replicated stations (area: 1 m2) at two depths (11 and 22 m) from 1997 to 2005. Variation of living space (i.e. empty colony spaces) was computed by using colony width and high recorded annually. Impacts and long-term consequences of the 1999 and 2003 thermal anomalies were evaluated as changes in empty colony spaces. Over the 9 year monitoring, living space resulted more abundant at the deep stations (2947±617 cm3) than at the shallow ones (1652±494 cm3). Rapid decline in living space (90% and 94% reduction at 11 and 22 m stations, respectively) following the 1999 event was mainly due to the necrosis and reduction of the largest colonies. Differently, after the 2003 thermal anomaly the living space decline occurred gradually during the following 2 years. Interestingly, between the two events, colonies at the deep stations regained living space to pre-disturbance level (5671±1862 cm3) showing higher resilience to disturbance. Detecting effects of extreme events on bioconstructions and associated biota will contribute to the assessment of biodiversity changes and to predict future changes in threatened marine ecosystems.

To assess the impact of live interactive teledermatology consultations on changes in diagnosis, disease management, and clinical outcomes. We conducted a retrospective analysis of 1500 patients evaluated via live interactive teledermatology between 2003 and 2005 at the University of California, Davis. We compared diagnoses and treatment plans between the referring physicians and the teledermatologists. Patients with 2 or more teledermatology visits within a 1-year period were assessed for changes in clinical outcomes. Academic medical center with an established teledermatology program since 1996. Medical records were evaluated for 1500 patients who underwent live interactive teledermatology consultation. Patients seen for more than 1 teledermatology visit were included in the clinical outcome assessment. Live interactive teledermatology consultation. Changes in diagnosis, disease management, and clinical outcome. Compared with diagnoses and treatment plans from referring physicians, the 1500 live interactive teledermatology consultations resulted in changes in diagnosis in 69.9% of patients and changes in disease management in 97.7% of patients. Among 313 patients with at least 2 teledermatology visits within 1 year, clinical improvement was observed in 68.7% of patients. Multivariate analysis showed that changes in diagnosis (P = .01), changes in disease management (P < .001), and the number of teledermatology visits (P < .001) were significantly associated with improved clinical outcomes. Live interactive teledermatology consultations result in changes in diagnosis and disease management in most consultations. The numbers of live interactive teledermatology visits and changes in diagnosis and disease management are significantly associated with improved clinical outcomes.

Emergence and evolution of social self-management of Parkinson’s disease: study protocol for a 3-year prospective cohort study

PubMed Central

2014-01-01

Background Parkinson’s disease affects facial, vocal and trunk muscles. As symptoms progress, facial expression becomes masked, limiting the person’s ability to communicate emotions and intentions to others. As people with the disease live and reside in their homes longer, the burden of caregiving is unmitigated by social and emotional rewards provided by an expressive individual. Little is known about how adults living with Parkinson’s disease manage their social lives and how an inability to be emotionally expressive can affect social connections and health. Because social networks have been shown to be crucial to the overall well-being of people living with chronic diseases, research is needed on how expressive capacity affects life trajectories and health. Methods/Design The overall objective is to understand the emergence and evolution of the trajectories of the self-management of the social lives of people living with Parkinson’s disease. The central hypothesis is that expressive capacity predicts systematic change in the pattern of social self-management and quality of life outcomes. The specific aims of this 3-year longitudinal study of 120 people with the disease and a maximum of 120 care partners are: 1) characterize social self-management trajectories over a 3-year period; 2) estimate the degree to which expressive nonverbal capacity predicts the trajectory; and 3) determine the moderating effect of gender on the association between expressive capacity and change in social self-management. Each participant will be assessed 14 times to detect rapid and non-linear changes in social participation and management of social activities; social network; and social comfort, general health and well-being. Discussion This project will provide evidence to guide the development of interventions for supporting social integration of those living with Parkinson’s disease, thus leading to improved overall health. It focuses on the novel construct of social self-management and known factors—expressive capacity and gender—that contribute to stigmatization. The repeated measures design detects triggers of rapid changes in social and health outcomes. PMID:24885181

This study examined interactive relationships among ethnic identity, gender, time in the US, and changes in substance use outcomes among a school-based sample of 1,731 Mexican-heritage preadolescents (ages 9–13). Residual change multilevel models adjusting for school clustering and using multiply imputed data assessed changes from beginning to end of fifth grade in use of alcohol, cigarettes, marijuana and inhalants, and four substance use antecedents. Effects of ethnic identity were conditional on time in the US, and in opposite directions by gender. Among males living longer in the US, stronger ethnic identity predicted desirable changes in all but one outcome (substance offers). Among females living longer in the US, stronger ethnic identity predicted undesirable changes in alcohol use, pro-drug norms, and peer substance use. Interpretations focus on differential exposure to substance use opportunities and the erosion of traditional gender role socialization among Mexican-heritage youth having lived longer in the US.

The aims of this study were to determine among retirees: the associations of arthritis with limitations in physical functions, and whether these associations changed differently with age for those with arthritis versus without arthritis. We identified retirees from the Health and Retirement Study, a nationally representative longitudinal panel study of U.S. adults ≥51 years old. We calculated incidence density ratios (IDRs) using Poisson regression modeling with generalized estimating equations to estimate the associations between arthritis and limitations in four physical function measures (large muscle tasks, mobility, activities of daily living, and instrumental activities of daily living) adjusting for age, sex, race/ethnicity, marital status, education, total household income, depression, obesity, smoking, chronic conditions, physical activity, and cohort status. We examined interaction effects between arthritis and age to determine if the rate of change in physical function differed by arthritis status across age. Over 8 years (2004-2012), significantly more retirees with arthritis had limitations with large muscle tasks (IDR 2.1: 95% confidence interval 1.6, 2.8), mobility (IDR 1.6: 1.2, 2.2), activities of daily living (IDR 2.2: 1.0, 4.7), and instrumental activities of daily living (IDR 3.7: 1.9, 7.4) than retirees without arthritis. Retirees with arthritis did not develop limitations in mobility, activities of daily living, and instrumental activities of daily living at a different rate as they aged compared to those without arthritis. Arthritis was associated with a greater prevalence of physical function limitations. Preventing limitations caused by arthritis is a key strategy to prevent disability in retirees.

The scientific literature shows, that caring parents of children with chronic kidney disease experience profound changes of life-world in terms of their welfare and their health. The different experiences that by the child's illness influenced the life-world of the parents in the two stages of life "living with peritoneal dialysis" and "living after kidney transplantation" have not yet been described in the German literature. To study the changing life-world in the two stages of life "living with peritoneal dialysis" and "living after kidney transplantation" of the child, a single case study was carried out. The mother was interviewed using a problem-centered-interview. The analysis of the interview was based on Mayring's technique of content analysis (2002). The category system shows that mother's life-world is influenced by different experiences in both stages of life. Subjectively, the mother saw her greatest challenge during the "life with peritoneal dialysis" in following the hygienic rules and the prevention of peritation" was her fear that the donor kidney would be rejected by her child. The results of this study correspond to the results of previous studies in the English literature. Healthcare professionals, including nurses can use the results of this study to build up a professional relationship, for empathic support and for improvement of parental well-being. Further qualitative research should focus on healthcare professionals' view regarding the experiences and needs of caring parents of children with chronic kidney disease in order to compare with parents' view.

Considering Students' Out-of-School Lives and Values in Designing Learning Environments for Climate Change

What are the implications of social controversy for the teaching and learning of climate change science? How do the political dimensions of this controversy affect learners' attitudes towards and reasoning about climate change and climate science? Case studies from a pilot enactment of an ecological impacts of climate change curriculum explore these questions by describing how five high school students' understandings of climate change science developed at the intersection of political and scientific values, attitudes, and ways of knowing. Case studies combine qualitative, ethnographic methods including interviews and classroom video observations with quantitative pre/post-assessments of student conceptual understandings and weekly surveys of student engagement. Data indicate that students had initial perceptions of climate change informed by the media and their families—both supporting and rejecting the scientific consensus—that influenced how they engaged with the scientific evidence. While students who were initially antagonistic to anthropogenic climate change did develop conceptual understandings of the scientific evidence for human-influences on climate change, this work was challenging and at times frustrating for them. These case studies demonstrate the wide range of initial attitudes and understandings that students bring to the study of climate change. They also demonstrate that it is possible to make significant shifts in students' understandings of climate change science, even in students who were initially resistant to the idea of anthropogenic climate change. Finally, multiple case studies discuss ways that the learning that occurred in the classroom crossed out of the classroom into the students' homes and family talk. This work highlights how learners' pathways are shaped not only by their developing understanding of the scientific evidence but also by the political and social influences that learners navigate across the contexts of their lives. It underscores the need to understand and support students as they interact with climate change across the contexts of their lives.

As the effects of climate change become more profound, climate literacy becomes increasingly important. The American Meteorological Society (AMS) responds to this need through the publication of Our Changing Climate and Living With Our Changing Climate. Both publications incorporate the latest scientific understandings of Earth's climate system from reports such as IPCC AR5 and the USGCRP's Third National Climate Assessment. Topic In Depth sections appear throughout each chapter and lead to more extensive, multidisciplinary information related to various topics. Additionally, each chapter closes with a For Further Exploration essay, which addresses specific topics that complement a chapter concept. Web Resources, which encourage additional exploration of chapter content, and Scientific Literature, from which chapter content was derived can also be found at the conclusion of each chapter. Our Changing Climate covers a breadth of topics, including the scientific principles that govern Earth's climate system and basic statistics and geospatial tools used to investigate the system. Released in fall 2015, Living With Our Changing Climate takes a more narrow approach and investigates human and ecosystem vulnerabilities to climate change, the role of energy choices in affecting climate, actions humans can take through adaption, mitigation, and policy to lessen vulnerabilities, and psychological and financial reasons behind climate change denial. While Living With Our Changing Climate is intended for programs looking to add a climate element into their curriculum, Our Changing Climate is part of the AMS Climate Studies course. In a 2015 survey of California University of Pennsylvania undergraduate students using Our Changing Climate, 82% found it comfortable to read and utilized its interactive components and resources. Both ebooks illuminate the multidisciplinary aspect of climate change, providing the opportunity for a more sustainable future.

Abstract All over the world, health behaviour is considered a complex, far reaching and powerful phenomenon. People's lives are influenced by their own or others' health behaviour on a daily basis. Whether it has to do with smoking, drinking, pollution, global warming or HIV management, it touches lives and it challenges personal and community responses. Health behaviour, and health behaviour change, probably holds the key to many a person's immediate or prolonged life or death outcomes. The same can be said about communities, culture groups and nations. This SANPAD-funded study focused on research questions relating to health behaviour change for people living with HIV (PLWH) in the North-West Province in South Africa. It investigated whether a comprehensive community-based HIV stigma reduction intervention caused health behaviour change in PLWH. An quantitative single system research design with one pre- and four repetitive post-tests utilizing purposive sampling was used to test change-over-time in the health behaviour of 18 PLWH. The results of the study indicated statistical and/or practical significant change-over-time. The intervention not only addressed the health behaviour of PLWH, but also their HIV stigma experiences, HIV signs and symptoms and their quality of life in the context of being HIV positive. The recommendations include popularization of the comprehensive community-based HIV stigma reduction intervention and extending it to include a second intervention to strengthen health behaviour and quality of life for PLWH in the community at large.

We assessed changes in levels of support for smoke-free bars and restaurants among teens and young adults before and after implementation of a statewide smoke-free law. We measured support for smoke-free bars and restaurants among teens and young adults aged 16-24 years living in Minnesota (n=2,785) and five comparison states (n=404), up to 12 months before and up to six months after Minnesota's smoke-free law went into effect in October 2007. We compared changes in support among three subgroups-Minnesota participants who lived with a previous local smoke-free law, Minnesota participants who did not live with a previous local smoke-free law, and participants from the comparison states-before and after Minnesota's statewide smoke-free law went into effect. Support for smoke-free restaurants and bars among participants in Minnesota and comparison states increased after Minnesota's smoke-free law went into effect. Minnesotans, both those living with and without a previous local smoke-free law, showed similar increases in support for smoke-free restaurants as participants in comparison states. However, Minnesotans living without a previous local law showed larger increases in support for smoke-free bars than both those in comparison states and those living in Minnesota with a previous local smoke-free law. Our study employed a more robust design than similar studies and focused on the teen and young adult population. Our results will help advocates and policy makers demonstrate how public support for smoke-free laws increases following smoke-free legislation, particularly among those who were not previously living with a local smoke-free law.

2017-01-01

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

Ensuring access to timely and appropriate primary healthcare for people living in poverty is an issue facing all countries, even those with universal healthcare systems. The transformation of healthcare practices and organization could be improved by involving key stakeholders from the community and the healthcare system in the development of research interventions. The aim of this project is to stimulate changes in healthcare organizations and practices by encouraging collaboration between care teams and people living in poverty. Our objectives are twofold: 1) to identify actions required to promote the adoption of professional practices oriented toward social competence in primary care teams; and 2) to examine factors that would encourage the inclusion of people living in poverty in the process of developing social competence in healthcare organizations. This study will use a participatory action research design applied in healthcare organizations. Participatory research is an increasingly recognized approach that is helpful for involving the people for whom the research results are intended. Our research team consists of 19 non-academic researchers, 11 academic researchers and six partners. A steering committee composed of academic researchers and stakeholders will have a decision-making role at each step, including knowledge dissemination and recommendations for new interventions. In this project we will adopt a multiphase approach and will use a variety of methods, including photovoice, group discussions and interviews. The proposed study will be one of only a few using participatory research in primary care to foster changes aimed at enhancing quality and access to care for people living in poverty. To our knowledge this will be the first study to use photovoice in healthcare organizations to promote new interventions. Our project includes partners who are targeted for practice changes and improvements in delivering primary care to persons living in poverty. By involving knowledge users, including service recipients, our study is more likely to produce a transformation of professional practices and encourage healthcare organizations to take into account the needs of persons living in poverty.

2018-01-01

With population aging and change in family structure, the number of the elderly who live alone is rapidly increasing in Korea. The aim of this study was to explore the association between social relationships—especially newly formed formal social relationships (FSRs)—and suicidal ideation among Korean elderly who live alone. The elderly who live alone (N = 2509) from the 2014 Survey of Living Conditions and Welfare Needs of Older Koreans were analyzed using logistic regression. This study found that informal social relationships (ISRs) (eg, children, friends and neighbors) of the elderly who live alone had statistically significant association with suicidal ideation, whereas FSRs (eg, formal helper and social participation) did not have significant association with suicidal ideation. The findings of this study suggest that the Korean Government needs to strengthen public system for alleviating social isolation of the elderly living alone. Therefore, this study proposed 2 strategic approaches to maintain and strengthen ISRs and to develop different types of FSRs (eg, the measures to combine FSRs with ISRs, gatekeepers, etc).

2013-01-01

Background The 20th century’s rapid industrialization and urbanization brought important social changes to Taiwan, including an increased number of elders living alone, which has increased risk of depression for the elderly. This study aimed to evaluate the changing pattern regarding the effect of intergenerational exchanges on elders’ depressive symptoms from 1993 to 2007. Methods Data from the second-, fourth- and sixth-wave surveys of the Study of Health and Living Status of the Middle-Aged and Elderly in Taiwan were analyzed. This study collected elders’ individual sociodemographic characteristics, their self-reported health status and their intergenerational exchanges, including living with partners or with their children and their provision of care for their grandchildren. Information about elders’ depression was evaluated using the 5-item Epidemiological Studies Depression Scale (CES-D). Changes in elders’ intergenerational exchanges and depressive symptoms were compared during these study periods (chi-square test). Then, logistic regression was performed to determine how significantly elders’ intergenerational exchanges were associated with their depressive symptoms across the three years 1993, 1999 and 2007. Results The prevalence of elders living with partners decreased from 1993 to 2007 by 19%, and that of living with their children decreased from 1993 to 2007 by 7%. Conversely, the percentage of elders providing care for grandchildren dramatically increased, from 9% in 1993 to 21% in 2007. Elderly people had significantly fewer depressive symptoms in 2007 than in 1993. After adjusting for confounders, those living without a partner, living without children or providing no grandchild care had a greater risk of feeling lonely and being depressed. However, during the period 1993 to 2007, the impact on elders’ depression and loneliness of co-residing with a partner or with children decreased at the same time that the impact of their provision of grandchild care increased. In 2007, elders who provided no grandchild care were significantly more likely to feel lonely and sad as well as to have high CES-D scores; these strong associations were not found in 1993 and 1999. Conclusions This study illustrates how taking care of grandchildren protects against depression and loneliness in elderly Taiwanese. We argue the need, in an aging society, for improving intergenerational interaction and recommend careful evaluation of the interaction between population policies and those of social welfare, such as child care.

Nicholson, Roscoe; O'Brien, Catherine

2017-12-01

This random assignment waitlist control intervention study examined an implementation of the educational Boost Your Brain and Memory cognitive fitness intervention in 12 senior living organizations. Older adult participants ( n = 166) completed measures of brain health knowledge, use of memory techniques, physical and intellectual activity, and mindfulness, at baseline and after the intervention group's completion of the course. Changes in knowledge scores and in self-reported physical and intellectual activity increased significantly more for intervention participants than for waitlist controls at the conclusion of the course. There were no significant changes between the groups in mindfulness or use of memory techniques. This suggests that in senior living settings Boost Your Brain and Memory is effective in educating participants about brain healthy behaviors and in motivating behavioral change in the areas of physical and intellectual activity.

Physical and Chemical Interactions with Conspecifics Mediate Sex Change in a Protandrous Gastropod Crepidula fornicata.

2015-12-01

The protandrous marine snail Crepidula fornicata has been a theoretical and empirical model for studies of sex change for many decades. We investigated the social conditions under which sex change occurs in this species by manipulating physical and chemical contact with conspecifics. Male snails were either in physical and chemical contact with females or in chemical contact with, but physically isolated from, females. Males were tested both with living females and with empty, sterilized shells. Males that were physically touching a living female were less likely to change sex than the isolated controls, while males in chemical (but not physical) contact with females changed sex no slower than the isolated controls. These results provide experimental evidence that the factor controlling sex change in C. fornicata is due to a contact-borne inhibitor associated with female conspecifics. These findings serve as a basis for future studies of sex change in this model system. © 2015 Marine Biological Laboratory.

Changes in ambient dose equivalent rates noted through vehicle-borne surveys have elucidated ecological half-lives of radioactive caesium in the environment. To confirm that the ecological half-lives are appropriate for predicting ambient dose equivalent rates within living areas, it is important to ascertain ambient dose equivalent rates on/around roads. In this study, radiation monitoring on/around roads at Kawamata town, located about 37 km northwest of the Fukushima Daiichi Nuclear Power Plant, was performed using monitoring vehicles and survey meters. It was found that the ambient dose equivalent rates around roads were higher than those on roads as of October 2012. And withal the ecological half-lives on roads were essentially consistent with those around roads. With dose predictions using ecological half-lives on roads, it is necessary to make corrections to ambient dose equivalent rates through the vehicle-borne surveys against those within living areas. © The Author 2015.

In response to the growing attention to integrated health care and the cultural change movement in nursing homes, this study examines the lived experiences of nursing home social workers to better understand their role perceptions, job satisfaction, and relationship with other staff members. Hermeneutic phenomenology was used in order to understand the lived experience of being a nursing home social worker. Ten nursing home social workers were recruited from a southern state and individual interviews were conducted. From the interviews, four themes emerged: challenge, coping, mattering, and rewarding. Guided by identity negotiation theory and social identity theory, these findings are discussed. Also, implications for social work education, nursing home administration, and policy is discussed.

Introduction Global scale up of antiretroviral therapy is changing the context of HIV-related stigma. However, stigma remains an ongoing concern in many countries. Groups of people living with HIV can contribute to the reduction of stigma. However, the pathways through which they do so are not well understood. Methods This paper utilizes data from a qualitative study exploring the impact of networked groups of people living with HIV in Jinja and Mbale districts of Uganda. Participants were people living with HIV (n=40), members of their households (n=10) and their health service providers (n=15). Data were collected via interviews and focus group discussions in 2010, and analyzed inductively to extract key themes related to the approaches and outcomes of the groups’ anti-stigma activities. Results Study participants reported that HIV stigma in their communities had declined as a result of the collective activities of groups of people living with HIV. However, they believed that stigma remained an ongoing challenge. Gender, family relationships, social and economic factors emerged as important drivers of stigma. Challenging stigma collectively transcended individual experiences and united people living with HIV in a process of social renegotiation to achieve change. Groups of people living with HIV provided peer support and improved the confidence of their members, which ultimately reduced self-stigma and improved their ability to deal with external stigma when it was encountered. Conclusions Antiretroviral therapy and group-based approaches in the delivery of HIV services are opening up new avenues for the collective participation of people living with HIV to challenge HIV stigma and act as agents of social change. Interventions for reducing HIV stigma should be expanded beyond those that aim to increase the resilience and coping mechanisms of individuals, to those that build the capacity of groups to collectively cope with and challenge HIV stigma. Such interventions should be gender sensitive and should respond to contextual social, economic and structural factors that drive stigma. PMID:24242256

Live coral cover in the fossil record: an example from Holocene reefs of the Dominican Republic

Lescinsky, H.; Titus, B.; Hubbard, D.

2012-06-01

Fossil reefs hold important ecological information that can provide a prehuman baseline for understanding recent anthropogenic changes in reefs systems. The most widely used proxy for reef "health," however, is live coral cover, and this has not been quantified in the fossil record because it is difficult to establish that even adjacent corals were alive at the same time. This study uses microboring and taphonomic proxies to differentiate between live and dead corals along well-defined time surfaces in Holocene reefs of the Enriquillo Valley, Dominican Republic. At Cañada Honda, live coral cover ranged from 59 to 80% along a contemporaneous surface buried by a storm layer, and the reef, as a whole had 33-80% live cover within the branching, mixed, massive and platy zones. These values equal or exceed those in the Dominican Republic and Caribbean today or reported decades ago. The values from the western Dominican Republic provide a geologic baseline against which modern anthropogenic changes in Caribbean reefs can be considered.

The aim of this study was to assess the association between changes in living arrangement and the initiation of daily smoking and monthly risky single-occasion drinking (RSOD) in a cohort of young Swiss men. Longitudinal cohort study. The sample consisted of 4662 young men drawn from the Cohort Study on Substance Use Risk Factors who lived with their family at baseline. Follow-up assessments occurred 15 months later. Multiple regression models were adjusted for individual and family factors (family model), as well as for individual and peer-related factors (peer model). Relative to those still living with their parents at follow-up (n = 3845), those who had moved out (n = 817) were considerably more likely to have taken up smoking or RSOD after adjusting for several individual, family, and peer-related variables: OR (daily smoking) = 1.67 (95% CI 1.15-2.41) (P = 0.007) and OR (monthly RSOD) = 1.42 (95% CI 1.08-1.88) (P = 0.012). The strongest family-related predictors of smoking initiation were family structure and the lack of parental regulation and the strongest peer-related factors alcohol/drug problems in peers. Meanwhile, the strongest peer-related predictors of RSOD initiation were peer pressure (misconduct), perceived social support from friends, and perceived social support from a significant other, whereas family factors were not associated with RSOD initiation. Further subanalyses were conducted to examine the impact of different living arrangement changes on substance use initiation and revealed that living with peers at follow-up was associated with the greatest risk. We identified a strong association between moving out of one's parents' home and daily smoking and monthly RSOD initiation in young Swiss men. Moving out to live with peers was an especially strong predictor of substance use initiation. Campaigns that aim to prevent heavy smoking and drinking should be intensified at the end of obligatory school. Copyright © 2016 The Royal Society for Public Health. Published by Elsevier Ltd.

This study's aims were to determine the efficacy and tolerability of rasagiline, a selective monoamine oxidase inhibitor B, for PD patients with mild cognitive impairment. Patients on stable dopaminergic therapy were randomized to adjunct rasagiline 1 mg/day or placebo in this 24-week, double-blind, placebo-controlled, multisite study. The primary endpoint was mean change from baseline to week 24 on the Scales for Outcomes of Parkinson's Disease-Cognition total score. Key secondary measures included changes in cognition, activities of daily living, motor scores, and Clinical Global Impression of Change, as well as safety and tolerability measures. Of the 170 patients randomized, 151 (88.2%) completed the study. Change in Scales for Outcomes of Parkinson's Disease-Cognition scores were not significantly different in the rasagiline and placebo groups (adjusted mean: 1.6 [standard error {SE} = 0.5] vs. 0.8 [SE = 0.5] points; LS means difference = 0.8; 95% confidence interval: -0.48, 2.05; P = 0.22). There were no between-group differences in change in the MoCA (p=0.84) or Penn Daily Activities Questionnaire (P = 0.48) scores or in the distribution of Alzheimer's Disease Cooperative Study-Clinical Global Impression of Change modified for mild cognitive impairment (P = 0.1). Changes in motor (UPDRS part III; P = 0.02) and activities of daily living (UPDRS part II; P < 0.001) scores favored rasagiline. Rasagiline was well tolerated; the most common adverse events in both groups were falls and dizziness. Rasagiline treatment in PD patients with mild cognitive impairment was not associated with cognitive improvement. Rasagiline did not worsen cognition, improved motor symptoms and activities of daily living, and was well tolerated in elderly cognitively impaired patients. © 2016 International Parkinson and Movement Disorder Society. © 2016 International Parkinson and Movement Disorder Society.

To describe prevalence trends in hospitalized live births affected by placental transmission of alcohol and drugs, as well as prevalence trends among parturient women hospitalized for liveborn delivery and diagnosed with substance abuse problems in the United States from 1999 to 2008. Comparison of the two sets of trends helps determine whether the observed changes in neonatal problems over time were caused by shifts in maternal substance abuse problems. This study independently identified hospitalized live births and maternal live born deliveries from discharge records in the Nationwide Inpatient Sample, one of the largest hospital administrative databases. Substance-related diagnosis codes on the records were used to identify live births affected by alcohol and drugs and parturient women with substance abuse problems. The analysis calculated prevalence differences and percentage changes over the 10 years, with Loess curves fitted to 10-year prevalence estimates to depict trend patterns. Linear and quadratic trends in prevalence were simultaneously tested using logistic regression analyses. The study also examined data on costs, primary expected payer, and length of hospital stays. From 1999 to 2008, prevalence increased for narcotic- and hallucinogen-affected live births and neonatal drug withdrawal syndrome but decreased for alcohol- and cocaine-affected live births. Maternal substance abuse at delivery showed similar trends, but prevalence of alcohol abuse remained relatively stable. Substance-affected live births required longer hospital stays and higher medical expenses, mostly billable to Medicaid. The findings highlight the urgent need for behavioral intervention and early treatment for substance-abusing pregnant women to reduce the number of substance-affected live births.

Results From 1999 to 2008, prevalence increased for narcotic- and hallucinogen-affected live births and neonatal drug withdrawal syndrome but decreased for alcohol- and cocaine-affected live births. Maternal substance abuse at delivery showed similar trends, but prevalence of alcohol abuse remained relatively stable. Substance-affected live births required longer hospital stays and higher medical expenses, mostly billable to Medicaid. Conclusions The findings highlight the urgent need for behavioral intervention and early treatment for substance-abusing pregnant women to reduce the number of substance-affected live births.

Through development of Coordinated Care Organizations (CCOs), Oregon's version of the Accountable Care Organization (ACO) for Medicaid beneficiaries, Oregon is redesigning the healthcare system delivering care to some of its most vulnerable citizens. While clinicians are central to healthcare transformation, little is known about the impact on their role. The aim of this study was to understand the current and perceived effect CCO-related changes have on Oregon physicians' professional and personal lives. This qualitative observational study involved semi-structured interviews, conducted between March and October, 2013, of twenty-two purposively selected physicians who varied in years of practice, gender, employment status, specialty, and geographic location from three different CCOs. A grounded theory approach was used to analyze data. Physicians expressed uncertainty and ambiguity about the CCO model, reporting minor financial changes in the first year, but anticipating future reimbursement changes; new team-based care roles and responsibilities, accountability for quality incentive measures; and effects of CCO implementation on their personal lives. To meet CCO model changes and requirements, physicians requested collegial networking, team-based care training, and data system and information technology support for undergoing health system transformation. Although perhaps not immediate, healthcare reform can have a real and perceived impact on physicians' professional and personal lives. Attention to the impact of healthcare reform on physicians' personal and professional lives is important to ensure strategies are implemented to maintain a viable workforce, professional satisfaction, financial sustainability, and quality of care.

Family self-tailoring: Applying a systems approach to improving family healthy living behaviors.

PubMed

Moore, Shirley M; Jones, Lenette; Alemi, Farrokh

2016-01-01

The adoption and maintenance of healthy living behaviors by individuals and families is a major challenge. We describe a new model of health behavior change, SystemCHANGE (SC), which focuses on the redesign of family daily routines using system improvement methods. In the SC intervention, families are taught a set of skills to engage in a series of small, family self-designed experiments to test ideas to change their daily routines. The family system-oriented changes brought about by these experiments build healthy living behaviors into family daily routines so that these new behaviors happen as a matter of course, despite wavering motivation, willpower, or personal effort on the part of individuals. Case stories of the use of SC to improve family healthy living behaviors are provided. Results of several pilot tests of SC indicate its potential effectiveness to change health living behaviors across numerous populations. Copyright © 2016 Elsevier Inc. All rights reserved.

The relationship between aging and increased life expectancy in the overall population likely contributes to a higher frequency rate and incidence of illnesses and functional disabilities. Physical dependence and cognitive impairment might hinder the performance of activities and result in an overload of care duties for the patient's family and the healthcare system. The aim of this study was to compare the functional and cognitive changes exhibited by the elderly over a 6-month period. This longitudinal and observational study was conducted in a sample of 167 elderly people, who were selected from the database of the Network of Studies on Frailty in Brazilian Elderly, Universidade Federal de Minas Gerais - UFMG. The participants submitted to the Mini Mental State Examination (MMSE), Katz Index, Lawton and Brody's scale and responded to items on Advanced Activities of Daily Living (AADLs). We analyzed the data using multivariate regression models. The participants' functional capacity exhibited reduced performance of specific instrumental activities of daily living (IADLs), p=0.002, and basic activities of daily living (BADLs), p=0.038. Living alone (odds ratio (OR), 2.53; 95% confidence interval (CI), 1.09-5.87) and work status (OR, 2.52; 95% CI, 1.18-5.41) were associated with changes in the IADLs. The scores in the AADL scale (p=0.163) and MMSE (p=0.059) did not exhibit any significant difference during the study period. The participants with better cognitive function were more independent in their performance of AADLs and IADLs. The results depict specific patterns of loss and stability of functional capacity in community-dwelling elderly.

In 2014, ACE (Alliance for Climate Education) evaluated the impact of its 45-minute live climate edutainment education program on the knowledge, attitudes and behavior of high school students with respect to climate change. The results showed gains in knowledge, increased engagement, as well as increased communication about climate change with number of students reporting talking about climate change with friends and family more than doubling. In 2016, ACE launched a digital version of its in-person edutainment education program, a 40-minute video version of the live program. This digital version, Our Climate Our Future (OCOF), has now been used by nearly 4,000 teachers nationwide and viewed by over 150,000 students. We experimentally tested the impact of the digital program (OCOF) compared to the live program and a control group. The experiment was conducted with 709 students in 27 classes at two North Carolina public high schools. Classes were assigned to one of three conditions: digital, live and control. In the digital version, students watched the 40-minute OCOF video featuring the same educator that presented the live program. In the live version, students received an identical 40-minute live presentation by an ACE staff educator The control group received neither treatment. When compared to controls, both programs were effective in positively increasing climate change knowledge, climate justice knowledge, perceived self-efficacy to make climate-friendly behavior changes, and beliefs about climate change (all statistically significant at or above P<.01). In the areas of hope that people can solve climate change and intent to change behavior, only the live program showed significant increases. In these two areas, it may be that an in-person experience is key to affecting change. In light of these positive results, ACE plans to increase the use of OCOF in schools across the country to assist teachers in their efforts to teach about climate change.

Manipulating protein conformations for exploring protein structure-function relationship has shown great promise. Although protein conformational changes under pulling force manipulation have been extensively studied, protein conformation changes under a compressive force have not been explored quantitatively. The latter is even more biologically significant and relevant in revealing protein functions in living cells associated with protein crowdedness, distribution fluctuations, and cell osmotic stress. Here we report our experimental observations on abrupt ruptures of protein native structures under compressive force, demonstrated and studied by single-molecule AFM-FRET spectroscopic nanoscopy. Our results show that the protein ruptures are abrupt and spontaneous events occurred when the compressive force reaches a threshold of 12-75 pN, a force amplitude accessible from thermal fluctuations in a living cell. The abrupt ruptures are sensitive to local environment, likely a general and important pathway of protein unfolding in living cells.

Chronic illness models are normally used to explain and predict the experience of living with a long-term condition. The aim of this study was to present the findings of narrative interviews with stroke survivors and their family carers to understand their experiences of stroke. We interviewed five people with stroke and three family carers from the United Kingdom. We used thematic analysis to generate themes from their narrative accounts and then linked them to broader theoretical perspectives while influenced by the concept of reinterpretation of life. The narrative accounts of participants are mainly structured based on how their changed bodies poststroke changed their identities and roles and consequently their relationships with others. In this study, we underline the need for using methods like narrative to explain strategies that people use to make sense of their experiences of living with a long-term condition such as stroke.

This study examined potential discriminators of groups of older adults showing different patterns of stability or change in loneliness over 5 years: those who became lonely, overcame loneliness, were persistently lonely, and were persistently not lonely. Discriminant function analysis results showed that the persistently lonely, compared with the persistently not lonely, were more often living alone, widowed, and experiencing poorer health and perceived control. Moreover, changes in living arrangements and perceived control predicted loneliness change. In conclusion, perceiving that one is able to meet social needs is a predictor of loneliness and loneliness change and appears to be more important than people’s friendships. Because the predictors were better able to predict entry into loneliness, results point to the promise of prevention approaches to loneliness interventions. PMID:27867246

A recipe for mealtime resilience for families living with dementia.

Wong, Fiona; Keller, Heather H; Schindel Martin, Lori; Sutherland, Olga

2015-09-01

To date, research delving into the narratives of persons living with dementia is limited. Taking part in usual mealtime activities such as preparing food can sustain the identity of persons living with dementia. Yet if capacity for mealtime activities changes, this can put a strain or demand on the family, which must adjust and adapt to these changes. The aim of this study was to develop an in-depth story of resilience in one family living with dementia that was experiencing mealtime changes. Thematic narrative analysis following the elements of Clandinin and Connelly's (2000) 3D narrative inquiry space was used. One family's dementia journey was highlighted using the metaphor of a baking recipe to reflect their story of resilience. Developing positive strategies and continuing to learn and adapt were the two approaches used by this resilient family. Reminiscing, incorporating humour, having hope and optimism, and establishing social support were specific strategies. This family continued to learn and adapt by focusing on their positive gains and personal growth, accumulating life experiences, and balancing past pleasures while adapting to the new normal. Future work needs to further conceptualise resilience and how it can be supported in families living with dementia. © 2014 Nordic College of Caring Science.

Botanic gardens science for conservation and global change.

PubMed

Donaldson, John S

2009-11-01

The contributions of botanic gardens to conservation biology and global-change research need to be understood within the context of the traditional strengths of such gardens in herbarium collections, living collections and interactions with the public. Here, I propose that research in conservation planning, modelling species responses to climate change, conservation of threatened species and experimental tests of global change build on the core strengths of botanic gardens. However, there are limits to what can be achieved through traditional gardens-based programs, and some botanic gardens have adapted their research to include studies of threatening processes and to monitor and verify global-change impacts. There is an opportunity for botanic gardens to use their living collections more effectively in global-change research and for them to have a role in linking biodiversity conservation with benefits derived from ecosystem services.

2005-02-01

Although the fields of leisure studies and recreation and parks were founded on addressing health and wellness needs of people, only recently have these needs been addressed by major, systematic research efforts. This paper examines the origins of leisure studies and the study of recreation behavior and park use and their potential contribution to active living research. Over the past 2 decades, leisure studies research has generated a body of literature pertinent to understanding and increasing active living, including studies on time use, motivation for initiating and maintaining activity, influence of user fees, and urban park use. Environmental, transportation, and public recreation policy and management practices also are important considerations in recreation and parks research. This article concludes with a list of recommendations to integrate these and other considerations into transdisciplinary research on active living. Opportunities for leisure studies/recreation and park research on active living include studies of environmental, life span, and motivational influences; greater use of objective measures of physical activity; and forming partnerships with allied industries to study physical activity. Among suggestions for facilitating such studies are training seminars for leisure studies and recreation researchers in active living research methods, changes in point allocation on grant proposals, providing incentives for transdisciplinary collaboration, and special journal issues.

Taking the Good Life to the Institution: Forensic Service Users' Perceptions of the Good Lives Model.

2016-05-01

Previous literature has highlighted a number of concerns about forensic care and rehabilitation by those who use the services. The Good Lives Model (GLM) is a strength-based, humanistic approach to offender rehabilitation that has been largely overlooked by forensic mental health practitioners. This study explored the impact of a brief GLM program on forensic service users' perceptions of rehabilitation, both within and beyond therapeutic programs, using a thematically linked, multiple-case study research design. Pre-post comparisons of participants' perceptions of rehabilitation suggested three different outcomes: definite change, subtle change, and no change. Possible factors associated with participants' divergent experiences included level of exposure to the GLM, readiness to change, and practitioners' adherence to the GLM and experience with the model. The importance of attending to the wider system for successful implementation of this innovative approach is highlighted. © The Author(s) 2015.

We report on real-time Raman spectroscopic studies of optically trapped living cells and organelles using an inverted confocal laser-tweezers-Raman-spectroscopy (LTRS) system. The LTRS system was used to hold a single living cell in a physiological solution or to hold a functional organelle within a living cell and consequently measured its Raman spectra. We have measured the changes in Raman spectra of a trapped yeast cell as the function of the temperature of the bathing solution and studied the irreversible cell degeneration during the heat denaturation. In addition, we measured the in-vitro Raman spectra of the nuclei within living pine cells and B. sporeformer, Strep. salivarius, and E. coli bacteria suspended in solution and showed the possibility of using LTRS system as a sensor for rapid identification of microbes in a fluid.

Living Shorelines: Assessing Geomorphic Change and Water Quality in an Urban Waterway

NASA Astrophysics Data System (ADS)

Huggins, A.; Schwartz, M. C.; Schmutz, P. P.

2017-12-01

In recent years, alternative strategies for shoreline armoring have become increasingly popular with coastal property owners. In Northwest Florida, local agencies implemented plans to attenuate wave action and reduce landward shore recession in an urban bayou by installing living shorelines. Living shorelines are constructed in the inter-tidal zones and incorporate both hard and soft structured stabilization. Generally, the hard component is fossilized oyster shells and the soft component is planted intertidal vegetation, such as Spartina alterniflora (Smooth cordgrass) and Juncus roemererianus (Black needlerush). Living shorelines were intended to comprise both ecological and societal implications by significantly slowing erosion processes for property owners, by utilizing oyster beds to improve water quality, and by fostering new ecological habitats in the marsh grasses. The issue presented with living shoreline management is long-term studies have not been carried out on these engineered systems. For this study, geospatial technology was utilized to create 3D images of terrain by interpolation of data points using a TotalStation to compute geomorphic change. Additionally, water samples were analyzed using traditional wet chemistry laboratory methods to determine total oxidized nitrogen (TON), ammonium, and orthophosphate content in water. Over a short three-month preliminary study, sediment accretion was observed primarily within the vegetation with the bulk of the erosion occurring around the oyster beds. TON was detected at levels between 10 µM and 30 µM, ammonium up to 5 µM, and orthophosphate was only detected in very low levels, consistently < 2 µM. The project is in its infancy, as the topographic profiles and water quality data will be used to establish baseline data for future research to determine volumetric geomorphic change,and to set a standard for water quality trends, surrounding oyster beds and vegetation in response to climatic events.

Get Active Orlando: changing the built environment to increase physical activity.

Active Living by Design's Get Active Orlando partnership (GAO) focused on downtown Orlando's Community Redevelopment Area, including the Parramore Heritage District, home to many low-income and ethnically diverse residents, including many seniors. The area had undergone substantial development, and GAO aimed to incorporate active living considerations into the city's changing landscape. Get Active Orlando conducted a baseline survey of all streets, sidewalks, and bicycle lanes in the project area and identified a sequence of plans and policies in which to incorporate changes identified in the assessment. To create more immediate opportunities for active living, the partnership initiated a senior walking program, a bicycle refurbishment and giveaway program, and community bicycle-riding events, and led a social-marketing campaign that emphasized simple lifestyle changes. Get Active Orlando influenced adoption of public policies supporting active living in Orlando, including the Downtown Transportation Plan, Streetscape Guidelines, Design Standards Review Checklist, and growth management policies. Establishment of the Mayor's Advisory Council on Active Living is testament to the heightened significance of active living in Orlando. Initial assessment data served as a strong platform for policy change. Creating connections across disciplines including land-use planning, transportation, public health, and economic development allowed GAO to secure substantial policy change to influence design of the built environment. Engaging community members, including youth, as leaders was an important factor in program success. The physical environment in Orlando's Community Redevelopment Area is beginning to change as a reflection of a new policy framework designed to support active living.

Direct Force Measurements of Receptor-Ligand Interactions on Living Cells

NASA Astrophysics Data System (ADS)

Eibl, Robert H.

The characterization of cell adhesion between two living cells at the level of single receptor-ligand bonds is an experimental challenge. This chapter describes how the extremely sensitive method of atomic force microscopy (AFM) based force spectroscopy can be applied to living cells in order to probe for cell-to-cell or cell-to-substrate interactions mediated by single pairs of adhesion receptors. In addition, it is outlined how single-molecule AFM force spectroscopy can be used to detect physiologic changes of an adhesion receptor in a living cell. This force spectroscopy allows us to detect in living cells rapidly changing, chemokine SDF-1 triggered activation states of single VLA-4 receptors. This recently developed AFM application will allow for the detailed investigation of the integrin-chemokine crosstalk of integrin activation mechanisms and on how other adhesion receptors are modulated in health and disease. As adhesion molecules, living cells and even bacteria can be studied by single-molecule AFM force spectroscopy, this method is set to become a powerful tool that can not only be used in biophysics, but in cell biology as well as in immunology and cancer research.

Live-line working is an essential part in the operations in an electric power system. Live-line workers are required to wear shielding clothing. Shielding clothing, however, acts as a closed environment for the human body. Working in a closed environment for a long time can change the physiological responses of the body and even endanger personal safety. According to the typical conditions of live-line working, this study synthesizes environmental factors related to shielding clothing and the physiological factors of the body to establish the heart rate variability index RMSSD and the comprehensive security warning index SWI. On the basis of both indices, this paper proposes a security warning method and system for the safety live-line workers. The system can monitor the real-time status of workers during live-line working to provide security warning and facilitate the effective safety supervision by the live operation center during actual live-line working.

Ultrastructural and mechanical changes in tubular epithelial cells by angiotensin II and aldosterone as observed with atomic force microscopy.

Tubular epithelial cells (TECs) play an important pathophysiological role in the promotion of renal fibrosis. Quantitative analysis of the mechanical changes in TECs may be helpful in evaluating novel pharmacological strategies. Atomic force microscopy (AFM) is a common nanotechnology tool used for imaging and measuring interaction forces in biological systems. In this study, we used AFM to study ultrastructural and mechanical changes in TECs mediated by the renin-angiotensin-aldosterone system. We quantitatively analyzed changes in the mechanical properties of TECs using three extrinsic factors, namely, chemical fixation, angiotensin II (AT II), and aldosterone (AD). Fixed TECs were 11 times stiffer at the cell body and 3 times stiffer at the cell-cell junction compared to live TECs. After stimulation with AT II, live TECs were four times stiffer at the junctional area than at the cell body, while fixed TECs after AT II stimulation were approximately two times stiffer at the both cell body and cell-cell junction compared to fixed unstimulated TECs. Fixed TECs also reflected changes in the mechanical properties of TECs at the cell body region after AD stimulation. Together, our results suggest that cell stiffness at the cell body region may serve as an effective index for evaluating drugs and stimulation, regardless of whether the cells are live or fixed at the time of analysis. In addition, studying the changes to the intrinsic mechanical property of TECs after application of external stimuli may be useful for investigating pathophysiologic mechanisms and effective therapeutic strategies for renal injury.

Study of preservation dynamics of ureaplasma laboratory strain live cultures and their DNA in transport medium at varying temperature. The study was carried out in laboratory strains Ureaplasma urealyticum serotype 8 and Ureaplasma parvum serotype 1. The quantity of live ureaplasmas was determined by method of tenfold dilutions in liquid medium. The growth of ureaplasmas was registered by changes in the color of the cultivation medium due to its alkalization by metabolism products and expressed in CCU/ml. DNA quantity in samples was determined by real time PCR performed by using Florocenosis-micoplasmas-FL test system produced by ILS. Live ureaplasmas wer shown to be preserved in transport medium at 4 degrees C for 12 - 29 days, at 18 - 22 degrees C--for 9 - 20 days and at 37 degrees C--for only 2 days. In samples incubated at 37 degrees C the quantity of live ureaplasmas increased and then sharply decreased to 0, at lower temperature titers of the cells decreased smoothly. The quantity of ureaplasma DNA in the process of their incubation did not change significantly. Fundamental differences in the duration of survival of U. urealyticum strain and U. parvum strain in transport medium at varying temperature were not detected. Based on the studies performed a practical conclusion can be drawn that in cases of emergency when clinical material transportation is necessary its storage in transport medium for several days is acceptable.

Few studies have assessed the predictors of changes in commuting. This study investigated the associations between physical environmental characteristics and changes in active commuting. Adults from the population-based European Prospective Investigation into Cancer (EPIC)-Norfolk cohort self-reported commuting patterns in 2000 and 2007. Active commuters were defined as those who reported 'always' or 'usually' walking or cycling to work. Environmental attributes around the home and route were assessed using Geographical Information Systems. Associations between potential environmental predictors and uptake and maintenance of active commuting were modelled using logistic regression, adjusting for age, sex and BMI. Of the 2757 participants (62% female, median baseline age: 52, IQR: 50-56 years), most were passive commuters at baseline (76%, n = 2099) and did not change their usual commute mode over 7 years (82%, n = 2277). In multivariable regression models, participants living further from work were less likely to take up active commuting and those living in neighbourhoods with more streetlights were more likely to take up active commuting (both p < 0.05). Findings for maintenance were similar: participants living further from work (over 10 km, OR: 0.06; 95% CI: 0.25 to 0.13) and had a main or secondary road on route were more likely to maintain their active commuting (OR: 0.52; 95% CI: 0.28 to 0.98). Those living in neighbourhoods with greater density of employment locations were more likely to maintain their active commuting. Co-locating residential and employment centres as well as redesigning urban areas to improve safety for pedestrians and cyclists may encourage active commuting. Future evaluative studies should seek to assess the effects of redesigning the built environment on active commuting and physical activity.

In the past two decades this region has been impacted by expanding coastal development, the largest cyclone ever recorded in the Arabian Sea, and a large-scale harmful algal bloom which resulted in mass mortality of reefs elsewhere in the Gulf of Oman. In 2012 we estimated live and dead coral using manta tow observations on 370 transects at 13 locations along the coastline and nearshore islands of Muscat Oman. We compared these estimates against observations made on 389 transects at the same 13 locations two decades earlier (1993-94) in order to determine long-term changes in benthos along the Muscat coast. Results were mapped and differences in categorical mean values for transect locations were statistically compared between survey years. Live hard and soft coral decreased over the past two decades at most survey sites, and decreases were significant at three exposed coastline sites and one semi-enclosed embayment. One sheltered embayment site showed a significant increase in live hard coral over the study period. Declines in live hard coral were associated with increases in dead coral framework at 8 of the 13 sites, but these changes were non-significant. We attribute these changes primarily to long-term effects of Cyclone Gonu, which struck the Oman coast in June 2007. The study results suggest that the manta tow method can be an effective way to detect long-term changes in coral and other benthic parameters over large areas, despite limitations on its precision.

Technology, Biopolitics, Rationalities and Choices: Recent Studies of Reproduction.

PubMed

Whittaker, Andrea

2015-01-01

New synergies across anthropology, science and technology studies (STS), legal studies and sociology, bring fresh theoretical perspectives to the study of reproduction. Recent works on reproduction trace some of the changing rationalities: from the tactics of feminist self-help health movements in 1970s and 1980s in the US, to the commercialized experience of pregnancy and the various configurations, policies and legalities addressing globalized genetic and assisted reproductive technologies. Reproductive decision-making is deeply entangled with neoliberalism, welfare reforms, racial and geographic disparities, economic stratification and cultural rationalities to produce inequalities. Studies of reproduction remain central to basic anthropological questions: what it means to be human, what constitutes life, how we live our lives, and how societies value particular lives.

Worldwide, refugees show a poorer mental and physical health than the populations among which they resettle. Little is known about the factors influencing health after resettlement. We examined the development of mental and physical health of refugees. As experienced living difficulties might decrease with obtaining a residence permit, we expected this to play a central role in health improvement after resettlement. A two-wave study conducted in the Netherlands among a cohort of 172 recent (n = 68) and longstanding (n = 104) permit holders from Afghanistan, Iran and Somalia between 2003 and 2011. Multivariate mediation analyses were conducted for the effect of changes in living difficulties on the association between change in status and changes in health. Health outcomes were self-reported general health, number of chronic conditions, PTSD and anxiety/depression. Recent permit holders had larger decreases in PTSD score (-0.402, CI -0.612; -0.192) and anxiety/depression score (-0.298, CI -0.464; -0.132), and larger improvements in self-rated general health between T1 and T2 (0.566, CI 0.183; 0.949) than longstanding permit holders. This association was not significant for changes in number of chronic conditions. Mediation analyses showed that the effect of getting a residence permit on health improvements transited through an improvement in living conditions, in particular employment and the presence of family/social support. These results suggest that change in residence permit is beneficial for health mainly because of the change in living difficulties. These results add up to the evidence on the role of social circumstances for refugees upon resettlement, and point at labour participation and social support as key mechanisms for health improvements. © The Author 2015.

Knee arthroplasties are an increasingly common treatment for osteoarthritis (OA) and the main indication is pain. Previous research states, however, that 15-20% of the operated patients are dissatisfied and 20-30% have persistent pain after surgery. This study is aimed at describing patients' experiences of living with knee OA when scheduled for surgery and further their expectations for future life after surgery. We interviewed 12 patients with knee OA scheduled for arthroplasty, using semi-structured qualitative interviews. The interviews were recorded and transcribed verbatim and analyzed using qualitative thematic analysis. Three categories were formulated with an overriding theme: "It's not just a knee, but a whole life." The three categories were "Change from their earlier lives," "Coping with knee problems," and "Ultimate decision to undergo surgery." The main finding was that knee OA affects the whole body and self, ultimately affecting the patients' lives on many levels. Further findings were that knee OA was considered to be the central focus in the participants' lives, which limited their level of activity, their ability to function as desired, their quality of life, and their mental well-being. Although surgery was considered to be the only solution, the expectations regarding the outcome differed. The participants were forced to change how they previously had lived their lives resulting in a feeling of loss. Thus, the experienced loss and expectations for future life must be put into the context of the individual's own personality and be taken into account when treating individuals with knee OA. The experience of living with knee OA largely varies between individuals. This mandates that patients' assessment should be considered on individual basis with regard to each patient.

Managing lifestyle change to reduce coronary risk: a synthesis of qualitative research on peoples' experiences.

2014-08-05

Coronary heart disease is an incurable condition. The only approach known to slow its progression is healthy lifestyle change and concordance with cardio-protective medicines. Few people fully succeed in these daily activities so potential health improvements are not fully realised. Little is known about peoples' experiences of managing lifestyle change. The aim of this study was to synthesise qualitative research to explain how participants make lifestyle change after a cardiac event and explore this within the wider illness experience. A qualitative synthesis was conducted drawing upon the principles of meta-ethnography. Qualitative studies were identified through a systematic search of 7 databases using explicit criteria. Key concepts were identified and translated across studies. Findings were discussed and diagrammed during a series of audiotaped meetings. The final synthesis is grounded in findings from 27 studies, with over 500 participants (56% male) across 8 countries. All participants experienced a change in their self-identity from what was 'familiar' to 'unfamiliar'. The transition process involved 'finding new limits and a life worth living' , 'finding support for self' and 'finding a new normal'. Analyses of these concepts led to the generation of a third order construct, namely an ongoing process of 'reassessing past, present and future lives' as participants considered their changed identity. Participants experienced a strong urge to get back to 'normal'. Support from family and friends could enable or constrain life change and lifestyle changes. Lifestyle change was but one small part of a wider 'life' change that occurred. The final synthesis presents an interpretation, not evident in the primary studies, of a person-centred model to explain how lifestyle change is situated within 'wider' life changes. The magnitude of individual responses to a changed health status varied. Participants experienced distress as their notion of self identity shifted and emotions that reflected the various stages of the grief process were evident in participants' accounts. The process of self-managing lifestyle took place through experiential learning; the level of engagement with lifestyle change reflected an individual's unique view of the balance needed to manage 'realistic change' whilst leading to a life that was perceived as 'worth living'. Findings highlight the importance of providing person centred care that aligns with both psychological and physical dimensions of recovery which are inextricably linked.

Effects of alprazolam on capture stress-related serum cortisol responses in Korean raccoon dogs (Nyctereutes procyonoides koreensis)

The purpose of this study was to evaluate the effect of alprazolam on the stress that Korean raccoon dogs (Nyctereutes procyonoides koreensis) may experience while caught in a live trap by measuring their serum cortisol response. The animals were placed in a live trap with or without being pretreated with oral doses of alprazolam. In both groups, pre-trap blood samples were initially collected without anesthesia before the animals were positioned in the live trap; then post-trap blood samples were collected after the animals had remained in the live trap for 2 h. Changes in cortisol levels were observed using a chemiluminescent immunoassay. The level of cortisol increased in the control group and decreased in the alprazolam-pretreatment group (p < 0.05). In this study, we demonstrated that alprazolam pretreatment reduced stress during live trap capture. PMID:21368571

2017-06-01

Climate change mitigation policies aim to reduce climate change through reducing greenhouse gas (GHG) emissions whereas adaption policies seek to enable humans to live in a world with increasingly variable and more extreme climatic conditions. It is increasingly realised that enacting such policies will have unintended implications for public health, but there has been less focus on their implications for wellbeing. Wellbeing can be defined as a positive mental state which is influenced by living conditions. As part of URGENCHE, an EU funded project to identify health and wellbeing outcomes of city greenhouse gas emission reduction policies, a survey designed to measure these living conditions and levels of wellbeing in Kuopio, Finland was collected in December 2013. Kuopio was the northmost among seven cities in Europe and China studied. Generalised estimating equation modelling was used to determine which living conditions were associated with subjective wellbeing (measured through the WHO-5 Scale). Local greenspace and spending time in nature were associated with higher levels of wellbeing whereas cold housing and poor quality indoor air were associated with lower levels of wellbeing. Thus adaption policies to increase greenspace might, in addition to reducing heat island effects, have the co-benefit of increasing wellbeing and improving housing insulation.

Women living with a spinal cord injury: perceptions about their changed bodies.

PubMed

Chau, Lisa; Hegedus, Lenke; Praamsma, Monate; Smith, Katey; Tsukada, Michiko; Yoshida, Karen; Renwick, Rebecca

2008-02-01

In this article we illuminate the narratives of women living with a spinal cord injury (SCI) with regard to (a) learning how to live with a changed body and (b) exploring the factors that influence how they feel toward their new bodies. An SCI produces immediate physical impairments resulting in a changed body, which can then have physical, emotional, and social consequences to these women. Through its focus on enhancing the body, physical therapy can help to promote a positive view of the self within the changed body. Our analysis of these women's experiences resulted in a fluid, three-phase framework of learning to live with a changed body that generally moves from (a) discomfort, to (b) moving toward comfort, to (c) comfort. Physical therapy can potentially influence the process of women's gaining comfort with their changed bodies following an SCI. The framework provides a basis for future research on adaptation following SCI.

Family Self-tailoring: Applying a Systems Approach to Improving Family Healthy Living Behaviors

PubMed Central

Moore, Shirley M.; Jones, Lenette; Alemi, Farrokh

2016-01-01

The adoption and maintenance of healthy living behaviors by individuals and families is a major challenge. We describe a new model of health behavior change, SystemCHANGE™ (SC), which focuses on the redesign of family daily routines using system improvement methods. In the SC intervention families are taught a set of skills to engage in a series of small, family self-designed experiments to test ideas to change their daily routines. The family system-oriented changes brought about by these experiments build healthy living behaviors into family daily routines so that these new behaviors happen as a matter of course, despite wavering motivation, willpower or personal effort on the part of individuals. Case stories of the use of SC to improve family healthy living behaviors are provided. Results of several pilot tests of SC indicate its potential effectiveness to change health living behaviors across numerous populations. PMID:27301950

The purpose of this study was to describe the lived experiences of persons with stomas related to sexual function and perceptions and their expectations of the ostomy nurses who care for them. Qualitative, phenomenological study. Fourteen persons living with an ostomy for least 2 months participated in the study. Data collection occurred at the ostomy and wound care unit at Dokuz Eylul University Hospital in Izmir, Turkey. Data were collected using an in-depth interview method. Interviews lasted from 20 to 60 minutes and were audiotaped. These recordings were transcribed and subjected to content analysis. Five themes emerged from the unstructured interviews: (1) changes in sexual life; (2) changes in body image; (3) fear and anxiety experienced during sexual intercourse; (4) psychological impact of sexual problems; and (5) expectations concerning sexual counseling from ostomy nurses. Study findings suggest that persons with ostomies experience changes in their body image, along with a decrease in sexual desire. Respondents described avoiding sexual intercourse, and abstained from sleeping with their partners. Male respondents described erectile dysfunction, and female respondents reported pain during sexual intercourse (dyspareunia). Participants stated that they did not feel adequately informed about these problems and desired to receive more information and support from ostomy nurses regarding sexual issues. Based on these findings, we recommend that ostomy nurses provide more counseling concerning sexual function and challenges following ostomy surgery.

Analysis of human living environmental quality of Shenyang-Dalian urban agglomerations has important theoretical and practical significance in rapid development region. A lot of investigations have been carried for Shenyang-Dalian urban agglomerations, including 38 counties. Based on the carrying capacity of resources, natural and socioeconomic environmental factors and regional changes of human living environmental evaluation are analyzed with the application of geographic information systems (GIS) software. By using principal component analysis (PCA) model and natural breaks classification (NBC) method, the evaluation results are divided into five categories. The results show that the human living environmental evaluation (HLEE) indexes of Dalian, Shenyang, and Liaoyang are higher than other counties. Among these counties, the human living environmental evaluation (HLEE) indexes of coastal counties are significantly higher than inland counties. The range of the human living environmental evaluation index in most of the study area is at III, IV, and V levels, accounting for 80.01%. Based on these results, it could illustrate the human living environment is in relatively suitable condition in Shenyang-Dalian urban agglomeration. PMID:27200212

The factors underlying the decline in living kidney donation in the United States since 2005 must be understood to inform strategies to ensure access to this option for future patients. Population-based estimates provide a better assessment of donation activity than do trends in the number of living donor transplants. Using data from the Scientific Registry of Transplant Recipients and the United States Census, we determined longitudinal changes in living kidney donation between 2005 and 2015, focusing on the effect of sex and income. We used multilevel Poisson models to adjust for differences in age, race, the incidence of ESRD, and geographic factors (including population density, urbanization, and daily commuting). During the study period, the unadjusted rate of donation was 30.1 and 19.3 per million population in women and men, respectively, and the adjusted incidence of donation was 44% higher in women (incidence rate ratio [IRR], 1.44; 95% confidence interval [95% CI], 1.39 to 1.49). The incidence of donation was stable in women (IRR, 0.95; 95% CI, 0.84 to 1.07) but declined in men (IRR, 0.75; 95% CI, 0.68 to 0.83). Income was associated with longitudinal changes in donation in both sexes, yet donation was stable in the highest two population income quartiles in women but only in the highest income quartile in men. In both sexes, living related donations declined, irrespective of income. In conclusion, living donation declined in men but remained stable in women between 2005 and 2015, and income appeared to have a greater effect on living donation in men.

Living matter—nexus of physics and biology in the 21st century

PubMed Central

Gardel, Margaret L.

2012-01-01

Cells are made up of complex assemblies of cytoskeletal proteins that facilitate force transmission from the molecular to cellular scale to regulate cell shape and force generation. The “living matter” formed by the cytoskeleton facilitates versatile and robust behaviors of cells, including their migration, adhesion, division, and morphology, that ultimately determine tissue architecture and mechanics. Elucidating the underlying physical principles of such living matter provides great opportunities in both biology and physics. For physicists, the cytoskeleton provides an exceptional toolbox to study materials far from equilibrium. For biologists, these studies will provide new understanding of how molecular-scale processes determine cell morphological changes. PMID:23112229

Neighborhood Built and Social Environments and Change in Weight Status over the Summer in Low-Income Elementary School Children.

Neighborhoods can provide opportunities for children to maintain a healthy weight or encourage unhealthy weight gain. Which neighborhood characteristics matter most remains poorly understood. We investigated links between neighborhood characteristics and weight change over the summer in children from 12 elementary schools with a high proportion of children from low-income families, in a mid-sized city in the US South. Mixed models and objective measures of height and weight were used. Study participants were 2770 children (average age 8.3, range 5.6⁻12.6 years). Older and female children and those who were already overweight were more likely to gain weight over the summer compared to younger, male, and normal weight children. Overweight children who lived near 2 or more small grocery stores gained less weight than overweight children who lived near 0 (weight change, p = 0.0468; body mass index (BMI) change, p = 0.0209) or 1 store (weight change, p = 0.0136; BMI change, p = 0.0033). Normal weight children living in neighborhoods with more large multifamily buildings gained more weight over the summer, although this association only approached significance. Additional efforts to understand which neighborhood factors have greater significance for overweight compared to normal weight children are warranted.

2018-01-01

Abstract Purpose of the Study To identify and examine the published qualitative research evidence relative to the experience of living with dementia. Design and Methods Metasynthesis was used as the methodological framework to guide data collection and analysis. Results Three themes were identified. The first theme considered the main condition-related changes experienced by people with dementia (PWD) and showed how these are interlinked and impact upon various areas of people’s lives. The second theme indicated that amidst these changes, PWD strive to maintain continuity in their lives by employing various resources and coping strategies. The third theme underlined the role of contextual factors. The reviewed evidence indicates that, the emerging experience of PWD and their potential to adjust to the continuous changes is influenced by access to and quality of both personal and contextual resources which remain in a constant, transactional relationship to each other. Implications The findings were interpreted and discussed in the context of relevant theoretical frameworks and research evidence. It was considered that current evidence and findings presented in this review can be further explored and expanded upon in a more systematic way through research conducted within the theoretical framework of dynamic systems theory. Further research would be also beneficial to explore the subjective experience of dementia from a participatory perspective. Exploring the application of these theoretical standpoints would contribute to the current state of knowledge and offer both PWD and carers fresh perspective on the nature of change and potential for adaptability in dementia.

Nanopipettes as Monitoring Probes for the Single Living Cell: State of the Art and Future Directions in Molecular Biology.

Examining the behavior of a single cell within its natural environment is valuable for understanding both the biological processes that control the function of cells and how injury or disease lead to pathological change of their function. Single-cell analysis can reveal information regarding the causes of genetic changes, and it can contribute to studies on the molecular basis of cell transformation and proliferation. By contrast, whole tissue biopsies can only yield information on a statistical average of several processes occurring in a population of different cells. Electrowetting within a nanopipette provides a nanobiopsy platform for the extraction of cellular material from single living cells. Additionally, functionalized nanopipette sensing probes can differentiate analytes based on their size, shape or charge density, making the technology uniquely suited to sensing changes in single-cell dynamics. In this review, we highlight the potential of nanopipette technology as a non-destructive analytical tool to monitor single living cells, with particular attention to integration into applications in molecular biology.

The goal of this longitudinal study was to assess the impact of economic change and increased market integration on subsistence strategies, living conditions, growth, and nutritional status of Ribeirinhos living in the rural Amazon, Brazil. Data on weight, height, skinfolds, and circumferences, as well as data on economic strategies and living conditions were collected from 469 individuals in 2002 and 429 in 2009. Of these, 204 individuals were measured on both occasions. Independent and paired t-tests were used to identify changes in nutritional status over time in the larger sample and smaller, longitudinal subsample, respectively. Multiple linear regressions were used to examine the relationship between changes in economic/living conditions and nutritional status in the longitudinal subsample. Results indicate modest improvements in linear growth (HAZ) and among male children the observed increase was related to enrollment in the Brazilian conditional cash transfer program, Bolsa Família (P = 0.03). In terms of short-term measures of nutritional status, we found a significant increase in ZTSF and a reduction in ZUMA in most age/sex groups. Among subadults, there was a negative relationship between ZUMA and access to electricity (P = 0.01) and positive relationship between ZUMA and the sale of the açaí fruit (P = 0.04). Significant changes in weight and BMI (P < 0.01) were found among adult females and both were negatively related to household cash income (P = 0.02 and P = 0.03, respectively). Despite significant changes in economic strategies and lifestyle, changes in nutritional status were modest which may be explained by increased food insecurity documented during this early stage of transition. 2010 Wiley-Liss, Inc.

Purpose: To investigate potential dietary changes among Southeast Asian international students living in self-catered accommodation while studying abroad and to consider implications for their health. Design: Participants were interviewed about their food preferences and behaviours in their home countries and during their undergraduate studies at the Australian National University. Setting: A university in Australia Participants: Study participants were full-time undergraduate students over 18 years of age from Southeast Asian countries studying at the Australian National University for at least one year, and living at self-catered accommodation. Methods: Thirty-one, in-depth, face-to-face qualitative interviews concerning usual diets were collected over a three month period in 2013. Interviews were coded and analysed with the aid of a computer program Atlas.ti. Results: The macro-nutrient content of Southeast Asian international students’ diets did not change a great deal when they moved to Australia. Most students replaced some preferred foods on occasions because they either could not afford them, they were not available or they lacked time to prepare them. These dietary changes were not necessarily reflected in changes to students’ weights and most students considered that they were as healthy as when they lived at home. Conclusion: As students’ adapt to a new food environment they reflexively manage potential health risks. Strong student networks and an accessible and healthy food environment would support students to make healthy dietary choices although additional information about healthy diets could facilitate this further.

To understand the daily lives of people with Parkinson's disease. Qualitative research, using as methodological and theoretical referential the Grounded Theory and Symbolic Interactionism, respectively. The in-depth interview was conducted with 30 people with Parkinson's disease. From data analysis, three themes were selected: Living with the disease - living with the treatment and changes in lifestyle; Modifying of one's job performance - revealing incapacity for work and the need to anticipate retirement and; Living with the stigma - the feeling of prejudice against the disease and the perceived limitations of the health services. Living with a chronic and non-transferable disease encompasses social, physical and cultural effects, along with the personal experiences of each unique individual. This study assists the improvement of care to people with the disease, because the care practice emerges from the interactions between the subjects.

Australian Aboriginal and Torres Strait Islanders are overrepresented in both the prevalence and incidence of the hepatitis C (HCV). HCV knowledge has been associated with a range of positive health behaviours. HCV knowledge has previously been investigated as a single construct; however examining different knowledge domains (i.e. transmission, risk of complications, testing and treatment) separately may be beneficial. This study investigated whether having greater HCV knowledge in different domains is associated with self-reported positive health behaviours. 203 Aboriginal people living with HCV completed a survey assessing HCV knowledge, testing and care, lifestyle changes since diagnosis and treatment intent. Respondents' knowledge was relatively high. Greater knowledge of risk of health complications was associated with undertaking more positive lifestyle changes since diagnosis. Respondents testing and treatment knowledge was significantly associated with incarceration, lifestyle changes since diagnosis and future treatment intentions. This study illustrates the importance of ensuring that knowledge is high across different HCV domains to optimise a range of positive health behaviours of Aboriginal people living with HCV. Future health promotion campaigns targeted at Aboriginal people living with HCV could benefit from broadening their focus from prevention to other domains such as testing and treatment.

Public health and clinical interventions for obesity in free-living adults may be diminished by individual compensation for the intervention. Approaches to predict weight outcomes do not account for all mechanisms of compensation, so they are not well suited to predict outcomes in free-living adults. Our objective was to quantify the range of compensation in energy intake or expenditure observed in human randomized controlled trials (RCTs). We searched multiple databases (PubMed, CINAHL, SCOPUS, Cochrane, ProQuest, PsycInfo) up to 1 August 2012 for RCTs evaluating the effect of dietary and/or physical activity interventions on body weight/composition. subjects per treatment arm ≥5; ≥1 week intervention; a reported outcome of body weight/body composition; the intervention was either a prescribed amount of over- or underfeeding and/or supervised or monitored physical activity was prescribed; ≥80% compliance; and an objective method was used to verify compliance with the intervention (for example, observation and electronic monitoring). Data were independently extracted and analyzed by multiple reviewers with consensus reached by discussion. We compared observed weight change with predicted weight change using two models that predict weight change accounting only for metabolic compensation. Twenty-eight studies met inclusion criteria. Overfeeding studies indicate 96% less weight gain than expected if no compensation occurred. Dietary restriction and exercise studies may result in up to 12-44% and 55-64% less weight loss than expected, respectively, under an assumption of no behavioral compensation. Compensation is substantial even in high-compliance conditions, resulting in far less weight change than would be expected. The simple algorithm we report allows for more realistic predictions of intervention effects in free-living populations by accounting for the significant compensation that occurs.

Can environmental improvement change the population distribution of walking?

PubMed

Panter, Jenna; Ogilvie, David

2017-06-01

Few studies have explored the impact of environmental change on walking using controlled comparisons. Even fewer have examined whose behaviour changes and how. In a natural experimental study of new walking and cycling infrastructure, we explored changes in walking, identified groups who changed in similar ways and assessed whether exposure to the infrastructure was associated with trajectories of walking. 1257 adults completed annual surveys assessing walking, sociodemographic and health characteristics and use of the infrastructure (2010-2012). Residential proximity to the new routes was assessed objectively. We used latent growth curve models to assess change in total walking, walking for recreation and for transport, used simple descriptive analysis and latent class analysis (LCA) to identify groups who changed in similar ways and examined factors associated with group membership using multinomial regression. LCA identified five trajectories, characterised by consistently low levels; consistently high levels; decreases; short-lived increases; and sustained increases. Those with lower levels of education and lower incomes were more likely to show both short-lived and sustained increases in walking for transport. However, those with lower levels of education were less likely to take up walking. Proximity to the intervention was associated with both uptake of and short-lived increases in walking for transport. Environmental improvement encouraged the less active to take up walking for transport, as well as encouraging those who were already active to walk more. Further research should disentangle the role of socioeconomic characteristics in determining use of new environments and changes in walking. Published by the BMJ Publishing Group Limited.

Stability of drugs during storage is important in forensic toxicology. For the analytes detected after intake of heroin (6-acetylmorphine (6-AM), morphine and codeine), long-time stability in real life whole blood samples are studied in only a small number of cases. Whole blood post mortem (n=37) and whole blood samples from living persons (n=22) containing morphine and codeine as well as 6-AM in blood or urine were selected. All cases represented intake of heroin. All samples contained fluoride and were initially analysed and stored in normal conditions (-20°C) for 4-9 years. All samples were then reanalysed using the same analytical methods and the results were compared. For samples from living persons, the median change in concentration was -3.7% for morphine and -5.3% for codeine. For post mortem samples, the median change in concentration was -12% for morphine and -11% for codeine. Both for samples from living persons and post mortem samples, the decrease in the concentrations from the original analysis to reanalysis were statistically significant for morphine and codeine. Regarding 6-AM, all living samples were negative at reanalysis. For post mortem samples, four cases still tested positive for 6-AM at reanalysis with a median change in the concentrations of -81%. There was no significant change in the morphine to codeine concentration ratios neither for living nor post mortem samples. This study showed that in real life whole blood samples, the concentrations of morphine and codeine are relatively stable during long-term storage at -20°C. 6-AM on the other hand, shows a considerable decrease in concentrations that is important to consider when interpreting results from reanalyses of forensic cases.

Structure-function relationships in the stem cell's mechanical world A: seeding protocols as a means to control shape and fate of live stem cells.

PubMed

Shape and fate are intrinsic manifestations of form and function at the cell scale. Here we hypothesize that seeding density and protocol affect the form and function of live embryonic murine mesenchymal stem cells (MSCs) and their nuclei. First, the imperative for study of live cells was demonstrated in studies showing changes in cell nucleus shape that were attributable to fixation per se. Hence, we compared live cell and nuclear volume and shape between groups of a model MSC line (C3H10T1/2) seeded at, or proliferated from 5,000 cells/cm2 to one of three target densities to achieve targeted development contexts. Cell volume was shown to be dependent on initial seeding density whereas nucleus shape was shown to depend on developmental context but not seeding density. Both smaller cell volumes and flatter nuclei were found to correlate with increased expression of markers for mesenchymal condensation as well as chondrogenic and osteogenic differentiation but a decreased expression of pre-condensation and adipogenic markers. Considering the data presented here, both seeding density and protocol significantly alter the morphology of mesenchymal stem cells even at very early stages of cell culture. Thus, these design parameters may play a critical role in the success of tissue engineering strategies seeking to recreate condensation events. However, a better understanding of how these changes in cell volume and nucleus shape relate to the differentiation of MSCs is important for prescribing precise seeding conditions necessary for the development of the desired tissue type. In a companion study (Part B, following), we address the effect of concomitant volume and shape changing stresses on spatiotemporal distribution of the cytoskeletal proteins actin and tubulin. Taken together, these studies bring us one step closer to our ultimate goal of elucidating the dynamics of nucleus and cell shape change as tissue templates grow (cell proliferation) and specialize (cell differentiation).

Living with chronic illness is a family affair that involves ongoing changes and challenges in everyday life. When life changes, the environment is important for family health and well-being. The relation between a place and a family is rarely described, and therefore the aim of this study was to explore the meaning of place for family well-being in families living with chronic illness. A qualitative design was chosen. Data were collected by photovoice combined with narrative family research interviews with 10 families living with chronic illness. A phenomenological hermeneutic analysis was used to interpret the data. The results showed that the meaning of place for family well-being in families living with chronic illness can be described as “a shared respite.” This main theme included three subthemes: “a place for relief,” “a place for reflection,” and “a place for re-creation.” These results were further understood by means of the concept place security. Feeling well means having place security in these families. Through knowledge about the meaning of place for family well-being, health care personnel can stimulate families living with chronic illness to find respite in places that contribute to well-being, both in familiar and new places.

2016-01-01

Growing attention in the past few decades has focused on improving care quality and quality of life for nursing home residents. Many traditional nursing homes have attempted to transform themselves to become more homelike emphasizing individualized care. This trend is referred to as nursing home culture change in the U.S. A promising culture change nursing home model, the Green House nursing home model, has shown positive psychological outcomes. However, little is known about whether the Green House nursing home model has positive effects on physical function compared to traditional nursing homes. To examine the longitudinal effects of the Green House nursing home model by comparing change patterns of activities of daily living function over time between Green House home residents and traditional nursing home residents. A retrospective longitudinal study. Four Green House organizations (nine Green House units and four traditional units). A total of 242 residents (93 Green House residents and 149 traditional home residents) who had stayed in the nursing home at least 6 months from admission. The outcome was activities of daily living function, and the main independent variable was the facility type in which the resident stayed: a Green House or traditional unit. Age, gender, comorbidity score, cognitive function, and depressive symptoms at baseline were controlled. All of these measures were from a minimum dataset. Growth curve modeling and growth mixture modeling were employed in this study for longitudinal analyses. The mean activities of daily living function showed deterioration over time, and the rates of deterioration between Green House and traditional home residents were not different over time. Four different activities of daily living function trajectories were identified for 18 months, but there was no statistical difference in the likelihood of being in one of the four trajectory classes between the two groups. Although Green House nursing homes are considered to represent an innovative model changing the nursing home environment into more person-centered, this study did not demonstrate significant differences in activities of daily living function changes for residents in the Green House nursing homes compared to traditional nursing homes. Given that the Green House model continues to evolve as it is being implemented and variations within and across Green House homes are identified, large-scale longitudinal studies are needed to provide further relevant information on the effects of the Green House model.

To describe conceptions of daily life in men living with a woman suffering from chronic obstructive pulmonary disease (COPD) in different stages of the disease. A chronic disease like COPD affects not only the person living with the illness, but also the spouse. Significant tasks and demands are placed on husbands. COPD has for a long time been considered more a man's disease than a woman's disease, but according to new evidence COPD is a vast problem in women, which requires support from their spouses. The literature review did not reveal any previous studies concerning conceptions of daily life in men living with women suffering from COPD in different stages. A phenomenographic study was conducted. Data were collected from October 2008 to October 2009 through semi-structured interviews with 19 men living with a woman suffering from COPD. Two main descriptive categories were found: (1) unchanged life situation where no support was needed; (2) changed life situation related to severity of COPD, where support was needed. The categories were described from the perspective 'ME and my spouse'. Even in their caregiving situation, the men continued with their own life and activities and did not put themselves in second place. No support was needed from healthcare or municipality when the women had mild COPD, but this changed when the COPD progressed. The men felt that daily life was burdened, restricted and the partner relationship was affected, even if the disease had not reached the final stage. The COPD forced them gradually into a caregiving role, and their daily life changed. They become more of a caregiver than a spouse. The men experienced lack of knowledge and support, and they felt that health professionals and municipality did not care about them.

The main purposes of this study are to compare the current statuses and activities of daily living (ADL) scores with the same parameters 15 years ago in fetal-type Minamata disease patients and to identify the communication disorders in these patients. An interview survey was conducted on 31 fetal-type Minamata disease patients mainly in 2002 concerning family structure, present status of care, their demand for care, communication status, and ADLs. Changes in ADLs during the past 15 years were also studied in 22 of the patients. Their mean ages were 45.5+/-3.5 (n=20) for males, and 46.1+/-1.9 (n=ll) for females. The average numbers of family of the patients was 2, and 15 patients lived alone. An analysis of ADLs showed that about 50% of the patients could not walk or take a bath, and 30 to 40% of the patients could not eat, excrete, change their clothes, or wash their face alone. Approximately 80% of the patients could understand daily conversation to some degree. However, their ability to express their demands and thoughts, put an idea into action, remember events, and live like ordinary people were significantly worse than their ability to understand daily conversation. The changes in the ADLs of the 22 patients were not significant for the past 15 years. However, two patients showed a rapid decrease for ADL of movement and 2 other patients died after an interview before 50 years of age. Appropriate care in daily living is an important issue for fetal-type Minamata disease patients. Further, the individual health care of such patients is an urgent issue and can prevent their health from rapidly deteriorating.

This study tracked change over time in sleep quantity, disturbance, and timing, and sleep's covariations with living situation, stress, social support, alcohol use, and grade point average (GPA) across four years of university in 186 Canadian students. Women slept longer as they moved through university, and men slept less; rise times were later each year. Students reported sleeping fewer hours, more sleep disturbances, and later rise times during years with higher stress. In years when students lived away from home, they reported more sleep disturbances, later bedtimes, and later rise times. Living on campus was associated with later bedtimes and rise times. Alcohol use was higher and GPA was lower when bedtimes were later. The implications of these observed patterns for understanding the correlates and consequences of university students' sleep are discussed.

Population Income and Longitudinal Trends in Living Kidney Donation in the United States

2015-01-01

Living kidney donation is declining in the United States. We examined longitudinal trends in living donation as a function of median household income and donor relation to assess the effect of financial barriers on donation in a changing economic environment. The zip code–level median household income of all 71,882 living donors was determined by linkage to the 2000 US Census. Longitudinal changes in the rate of donation were determined in income quintiles between 1999 and 2004, when donations were increasing, and between 2005 and 2010, when donations were declining. Rates were adjusted for population differences in age, sex, race, and ESRD rate using multilevel linear regression models. Between 1999 and 2004, the rate of growth in living donation per million population was directly related to income, increasing progressively from the lowest to highest income quintile, with annualized changes of 0.55 (95% confidence interval [95% CI], 0.14 to 1.05) for Q1 and 1.77 (95% CI, 0.66 to 2.77) for Q5 (P<0.05). Between 2005 and 2010, donation declined in Q1, Q2, and Q3; was stable in Q4; and continued to grow in Q5. Longitudinal changes varied by donor relationship, and the association of income with longitudinal changes also varied by donor relationship. In conclusion, changes in living donation in the past decade varied by median household income, resulting in increased disparities in donation between low- and high-income populations. These findings may inform public policies to support living donation during periods of economic volatility. PMID:25035519

Controls on terrestrial carbon feedbacks by productivity versus turnover in the CMIP5 Earth System Models

DOE Office of Scientific and Technical Information (OSTI.GOV)

Koven, C. D.; Chambers, J. Q.; Georgiou, K.

To better understand sources of uncertainty in projections of terrestrial carbon cycle feedbacks, we present an approach to separate the controls on modeled carbon changes. We separate carbon changes into four categories using a linearized, equilibrium approach: those arising from changed inputs (productivity-driven changes), and outputs (turnover-driven changes), of both the live and dead carbon pools. Using Coupled Model Intercomparison Project Phase 5 (CMIP5) simulations for five models, we find that changes to the live pools are primarily explained by productivity-driven changes, with only one model showing large compensating changes to live carbon turnover times. For dead carbon pools, themore » situation is more complex as all models predict a large reduction in turnover times in response to increases in productivity. This response arises from the common representation of a broad spectrum of decomposition turnover times via a multi-pool approach, in which flux-weighted turnover times are faster than mass-weighted turnover times. This leads to a shift in the distribution of carbon among dead pools in response to changes in inputs, and therefore a transient but long-lived reduction in turnover times. Since this behavior, a reduction in inferred turnover times resulting from an increase in inputs, is superficially similar to priming processes, but occurring without the mechanisms responsible for priming, we call the phenomenon "false priming", and show that it masks much of the intrinsic changes to dead carbon turnover times as a result of changing climate. These patterns hold across the fully coupled, biogeochemically coupled, and radiatively coupled 1 % yr −1 increasing CO 2 experiments. We disaggregate inter-model uncertainty in the globally integrated equilibrium carbon responses to initial turnover times, initial productivity, fractional changes in turnover, and fractional changes in productivity. For both the live and dead carbon pools, inter-model spread in carbon changes arising from initial conditions is dominated by model disagreement on turnover times, whereas inter-model spread in carbon changes from fractional changes to these terms is dominated by model disagreement on changes to productivity in response to both warming and CO 2 fertilization. However, the lack of changing turnover time control on carbon responses, for both live and dead carbon pools, in response to the imposed forcings may arise from a common lack of process representation behind changing turnover times (e.g., allocation and mortality for live carbon; permafrost, microbial dynamics, and mineral stabilization for dead carbon), rather than a true estimate of the importance of these processes.« less

Long-Term Live Cell Imaging of Cell Migration: Effects of Pathogenic Fungi on Human Epithelial Cell Migration.

PubMed

Wöllert, Torsten; Langford, George M

2016-01-01

Long-term live cell imaging was used in this study to determine the responses of human epithelial cells to pathogenic biofilms formed by Candida albicans. Epithelial cells of the skin represent the front line of defense against invasive pathogens such as C. albicans but under certain circumstances, especially when the host's immune system is compromised, the skin barrier is breached. The mechanisms by which the fungal pathogen penetrates the skin and invade the deeper layers are not fully understood. In this study we used keratinocytes grown in culture as an in vitro model system to determine changes in host cell migration and the actin cytoskeleton in response to virulence factors produced by biofilms of pathogenic C. albicans. It is clear that changes in epithelial cell migration are part of the response to virulence factors secreted by biofilms of C. albicans and the actin cytoskeleton is the downstream effector that mediates cell migration. Our goal is to understand the mechanism by which virulence factors hijack the signaling pathways of the actin cytoskeleton to alter cell migration and thereby invade host tissues. To understand the dynamic changes of the actin cytoskeleton during infection, we used long-term live cell imaging to obtain spatial and temporal information of actin filament dynamics and to identify signal transduction pathways that regulate the actin cytoskeleton and its associated proteins. Long-term live cell imaging was achieved using a high resolution, multi-mode epifluorescence microscope equipped with specialized light sources, high-speed cameras with high sensitivity detectors, and specific biocompatible fluorescent markers. In addition to the multi-mode epifluorescence microscope, a spinning disk confocal long-term live cell imaging system (Olympus CV1000) equipped with a stage incubator to create a stable in vitro environment for long-term real-time and time-lapse microscopy was used. Detailed descriptions of these two long-term live cell imaging systems are provided.

Taking the ruler to the jungle: single-molecule FRET for understanding biomolecular structure and dynamics in live cells.

Single-molecule Förster resonance energy transfer (smFRET) serves as a molecular ruler that is ideally posed to study static and dynamic heterogeneity in living cells. Observing smFRET in cells requires appropriately integrated labeling, internalization and imaging strategies, and significant progress has been made towards that goal. Pioneering studies have demonstrated smFRET detection in both prokaryotic and eukaryotic systems, using both wide-field and confocal microscopies, and have started to answer exciting biological questions. We anticipate that future technical developments will open the door to smFRET for the study of structure, conformational changes and kinetics of biomolecules in living cells.

To review studies on structural pulmonary and cardiac changes in SUDEP cases as well as studies showing pulmonary or cardiac structural changes in living epilepsy patients. We conducted electronic literature searches using the PubMed database for articles published in English, regardless of publication year, that included data on cardiac and/or pulmonary structural abnormalities in SUDEP cases or in living epilepsy patients during the postictal period. Fourteen postmortem studies reported pulmonary findings in SUDEP cases. Two focused mainly on assessing lung weights in SUDEP cases versus controls; no group difference was found. The other 12 reported descriptive autopsy findings. Among all SUDEP cases with available descriptive postmortem pulmonary examination, 72% had pulmonary changes, most often pulmonary edema/congestion, and, less frequently, intraalveolar hemorrhage. Eleven studies reported on cardiac pathology in SUDEP. Cardiac abnormalities were found in approximately one-fourth of cases. The most common findings were myocyte hypertrophy and myocardial fibrosis of various degrees. Among living epilepsy patients, postictal pulmonary pathology was the most commonly reported pulmonary abnormality and the most common postictal cardiac abnormality was transient left ventricular dysfunction - Takotsubo or neurogenic stunned myocardium. Cardiac and pulmonary pathological abnormalities are frequent among SUDEP cases, most commonly pulmonary edema/congestion and focal interstitial myocardial fibrosis. Most findings are not quantified, with subjective elements and undefined interobserver reliability, and lack of controls such as matched epilepsy patients who died from other causes. Further, studies have not systematically evaluated potential confounding factors, including postmortem interval to autopsy, paramedic resuscitation and IV fluids administration, underlying heart/lung disease, and risk factors for cardiac or pulmonary disease. Prospective studies with controls are needed to define the heart and lung changes in SUDEP and understand their potential relationship to mechanisms of death in SUDEP. Copyright © 2017 Elsevier Inc.

A rugby scrum's front row must act uniformly to transfer maximal horizontal force and improve performance. This study investigated the muscle activation patterns of lower extremity muscles in front row forwards during live and machine scrums at professional and amateur levels. Electromyography was collected bilaterally on vastus lateralis, rectus femoris and gastrocnemius muscles of 75 male rugby prop players during live and machine scrums. ANOVAs compared muscle reaction time, rate of change in muscle amplitude and muscle amplitude between groups and conditions. Cross-correlation analysis explored muscle synchronicity. There were significantly greater rates of change in each muscle amplitude in professional players than amateur players. Additionally, there was significantly quicker muscle reaction time in all muscles, and greater amplitude in vastus lateralis and gastrocnemius, during the live scrum vs. machine condition. The professional props produced more synchronised muscle activation than amateur players and all players produced more synchronised muscle activation against the scrum machine vs. live scrummage. The results indicate a higher skill proficiency and muscle synchronicity in professional players. While scrum machine training is ideally suited for functional muscle strengthening during practice, to truly simulate the requirements of the scrum, training should incorporate the live situation as much as possible.

Patterns of testosterone in three Nearctic-Neotropical migratory songbirds during spring passage.

PubMed

Covino, Kristen M; Morris, Sara R; Moore, Frank R

2015-12-01

Preparation for breeding may overlap extensively with vernal migration in long-distance migratory songbirds. Testosterone plays a central role in mediating this transition into breeding condition by facilitating changes to physiology and behavior. While changes in testosterone levels are well studied in captive migrants, these changes are less well known in free-living birds. We examined testosterone levels in free-living Nearctic-Neotropical migrants of three species during their vernal migration. Testosterone levels increased during the migratory period in males of all three species but significantly so in only two. Testosterone levels in females remained the same throughout their migration. Our results support the extensive overlap between vernal migration and breeding preparation in male songbirds. The pattern of testosterone changes during vernal migration is far from clear in females. Copyright © 2015 Elsevier Inc. All rights reserved.

Jakobsen, R. J.; Winters, S.; Gendreau, R. M.

1981-10-01

An ex vivo FT-IR/ATR experiment for studying blood protein adsorption at the molecular level is described. This experiment involves the use of live dogs pumping the blood through a arterial-veinal shunt to the ATR cell and back into the animal. The results from these live dog experiments are compared to results obtained using donated whole blood. These experiments demonstrate that FT-IR can be used to study aqueous, physiological, flowing solutions in real time with the sensitivity necessary to detect minor changes.

The gendered nature of filial piety--a study among Chinese Canadians.

PubMed

Chappell, Neena L; Kusch, Karen

2007-03-01

This paper examines the modern face of filial piety enactment among Chinese families living away from their homeland. It empirically assesses filial piety practices among a random sample of diasporic Chinese Canadians, by studying the role of sons, daughters and spouses in providing assistance with basic activities of daily living, instrumental activities of daily living and perceptions of support; the relative contribution of the traditional Chinese caring unit (son plus daughter-in-law) with assistance provided; whether source of assistance changes when amount of care is taken into account, when the gendered nature of tasks is taken into account and when controlling for other factors in multivariate analyses. N = 2,272 Chinese seniors (age 55+) living in seven cities across Canada. The findings reveal that, among these diasporic Chinese, patterns found in other Chinese societies are evident in their tendency to live with children, even when the spouse is still living, and the involvement of sons and the son/daughter-in-law unit in providing care. However, similar to recent findings for China, daughters and spouses are involved in all 3 areas of support examined and importantly, their involvement increases as more assistance is provided while that from sons decreases, notably in terms of IADL. The participation of daughters-in-law tends to be lower than that of either sons or daughters. The involvement of spouses increases for perceived or emotional support. The findings suggest a blending of Chinese and Canadian patterns of care and are discussed in terms of the changing but still gendered nature of care.

The meaning of women's experiences of living with multiple sclerosis.

PubMed

Olsson, Malin; Lexell, Jan; Söderberg, Siv

2008-04-01

We conducted a qualitative inquiry in order to describe the meaning of women's experiences of living with multiple sclerosis (MS). Multiple sclerosis is a chronic autoimmune disease of the central nervous system. The majority of persons living with MS are women. Living with MS has been described as difficult because of the uncertainty of the illness. Ten women with MS were interviewed and the interviews were analyzed with a phenomenological hermeneutic interpretation. In this study, we suggest that the meaning of living with MS for women can be understood as trying to maintain power and living with an unrecognizable body. The bodies of women with MS serve as hindrances in everyday life. Bodily changes evident to others impose feelings of being met in a different way, which can be understood as an expression of a violated dignity. At the same time, the women with MS struggle to protect their dignity.

Understanding adaptive genetic responses to climate change is a main challenge for preserving biological diversity. Successful predictive models for climate-driven range shifts of species depend on the integration of information on adaptation, including that derived from genomic studies. Long-lived forest trees can experience substantial environmental change across generations, which results in a much more prominent adaptation lag than in annual species. Here, we show that candidate-gene SNPs (single nucleotide polymorphisms) can be used as predictors of maladaptation to climate in maritime pine (Pinus pinaster Aiton), an outcrossing long-lived keystone tree. A set of 18 SNPs potentially associated with climate, 5 of them involving amino acid-changing variants, were retained after performing logistic regression, latent factor mixed models, and Bayesian analyses of SNP-climate correlations. These relationships identified temperature as an important adaptive driver in maritime pine and highlighted that selective forces are operating differentially in geographically discrete gene pools. The frequency of the locally advantageous alleles at these selected loci was strongly correlated with survival in a common garden under extreme (hot and dry) climate conditions, which suggests that candidate-gene SNPs can be used to forecast the likely destiny of natural forest ecosystems under climate change scenarios. Differential levels of forest decline are anticipated for distinct maritime pine gene pools. Geographically defined molecular proxies for climate adaptation will thus critically enhance the predictive power of range-shift models and help establish mitigation measures for long-lived keystone forest trees in the face of impending climate change.

This work presents a new strategy of the combination of surface plasmon resonance (SPR) and electrochemical study for real-time evaluation of live cancer cells treated with daunorubicin (DNR) at the interface of the SPR chip and living cancer cells. The observations demonstrate that the SPR signal changes could be closely related to the morphology and mass changes of adsorbed cancer cells and the variation of the refractive index of the medium solution. The results of light microscopy images and 3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyl-2H-tetrazolium bromide studies also illustrate the release or desorption of HepG2 cancer cells, which were due to their apoptosis after treatment with DNR. It is evident that the extracellular concentration of DNR residue can be readily determined through electrochemical measurements. The decreases in the magnitudes of SPR signals were linearly related to cell survival rates, and the combination of SPR with electrochemical study could be utilized to evaluate the potential therapeutic efficiency of bioactive agents to cells. Thus, this label-free, real-time SPR-electrochemical detection technique has great promise in bioanalysis or monitoring of relevant treatment processes in clinical applications.

Study on data acquisition system for living environmental information for biofication of living spaces

NASA Astrophysics Data System (ADS)

Shimoyama, Norihisa; Mita, Akira

2008-03-01

In Japan's rapidly aging society, the number of elderly people living alone increases every year. Theses elderly people require more and more to maintain as independent a life as possible in their own homes. It is necessary to make living spaces that assist in providing safe and comfortable lives. "Biofication of Living Spaces" is proposed with the concept of creating save and pleasant living environments. It implies learning from biological systems, and applying to living spaces features such as high adaptability and excellent tolerance to environmental changes. As a first step towards realizing "Biofied Spaces", a system for acquisition and storing information must be developed. This system is similar to the five human senses. The information acquired includes environmental information such as temperature, human behavior, psychological state and location of furniture. This study addresses human behavior as it is the most important factor in design of a living space. In the present study, pyroelectric infrared sensors were chosen for human behavior recognition. The pyroelectric infrared sensor is advantageous in that it has no limitation on the number of sensors put in a single space because sensors do not interfere with each other. Wavelet analysis was applied to the output time histories of the pyroelectric infrared sensors. The system successfully classified walking patterns with 99.5% accuracy of walking direction (from right or left) and 85.7% accuracy of distance for 440 patterns pre-learned and an accuracy of over 80% accuracy of walking direction for 720 non-learned patterns.

Disability Rises Gradually for a Cohort of Older Americans

PubMed Central

Brown, Dustin C.; Zajacova, Anna

2017-01-01

Objectives: We study changes in average disability over nearly two decades for a large epidemiological cohort of older Americans. As some people exit by mortality, do average disability levels for the living cohort rise rapidly, rise gradually, stay steady, or decline? Method: Data are from the Study of Asset and Health Dynamics Among the Oldest Old (AHEAD) cohort for 1993–2010. Cohort members are aged 70+ in 1993 (mean = 77.5 years), and the survivors are aged 87+ in 2010 (mean = 90.2 years). Personal care disability (activities of daily living), household management disability (instrumental activities of daily living), and physical limitations are studied. We study average disability for the living cohort over time and the disability histories for decedent and survivor groups. Results: Average disability rises gradually over time for the living cohort. Earlier decedent groups have higher average disability than later ones. Near death, disability rises sharply for all decedent groups. Longer surviving groups have less average disability, and slower disability increases, than shorter surviving groups. All results are repeated for younger cohort members (baseline age = 70–79 years), older ones (baseline age = 80+ years), women, and men. Discussion: As a cohort ages, average disability among living members increases gradually, signaling behavioral, psychological, and biological fitness in very old persons. PMID:26968638

This study summarizes information on diet and living patterns for the Marshallese. The data was derived from literature, answers to questionnaires, personal observations while living with the Marshallese for periods extending from months to years, and from direct participation in their activities. The results reflect the complex interactions of many influences, such as, the gathering of local foods the receipt of food aid through programs, such as, school-lunch, typhoon-relief, food distributed to populations displaced as a result of nuclear testing, and in recent times the availability of cash for the purchase of imported foods. The results identify these influences andmore » are therefore restricted to local food diets while recognizing that the living patterns are changing as local food gathering is replaced by other food supplies. The data will therefore provide the necessary information for input into models that will assess the radiological impacts attributable to the inhabitation of the Marshall Islands. It is recommended that this study should be continued for at least two to three years in order to more accurately identify trends in local food consumption and living patterns.« less

According to the World Health Organisation (WHO), global warming has the potential to dramatically disrupt some of life's essential requirements for health, water, air and food. Understanding how Australians perceive the risk of global warming is essential for climate change policy and planning. The aim of this study was to determine the prevalence of, and socio-demographic factors associated with, high levels of perceived likelihood that global warming would worsen, concern for self and family and reported behaviour changes. A module of questions on global warming was incorporated into the New South Wales Population Health Survey in the second quarter of 2007. This Computer Assisted Telephone Interview (CATI) was completed by a representative sample of 2004 adults. The weighted sample was comparable to the Australian population. Bivariate and multivariate statistical analyses were conducted to examine the socio-demographic and general health factors. Overall 62.1% perceived that global warming was likely to worsen; 56.3% were very or extremely concerned that they or their family would be directly affected by global warming; and 77.6% stated that they had made some level of change to the way they lived their lives, because of the possibility of global warming. After controlling for confounding factors, multivariate analyses revealed that those with high levels of psychological distress were 2.17 (Adjusted Odds Ratio (AOR)=2.17; CI: 1.16-4.03; P=0.015) times more likely to be concerned about global warming than those with low psychological distress levels. Those with a University degree or equivalent and those who lived in urban areas were significantly more likely to think that global warming would worsen compared to those without a University degree or equivalent and those who lived in the rural areas. Females were significantly (AOR=1.69; CI: 1.23-2.33; P=0.001) more likely to report they had made changes to the way they lived their lives due to the risk of global warming. A high proportion of respondents reported that they perceived that global warming would worsen, were concerned that it would affect them and their families and had already made changes in their lives because of it. These findings support a readiness in the population to deal with global warming. Future research and programs are needed to investigate population-level strategies for future action.

Level and change in perceived control predict 19-year mortality: findings from the Americans' changing lives study.

Perceived control plays an important role for health across adulthood and old age. However, little is known about the factors that account for such associations and whether changes in control (or control trajectory) uniquely predict major health outcomes over and above mean levels of control. Using data from the nationwide Americans' Changing Lives Study (House et al., 1990; N = 2,840, M age at T2: 56.32 years, range: 28-99, 64% women), we examined the extent to which mean levels and rates of change in perceived control over 16 years predict all-cause mortality over a 19-year follow-up period. Shared growth-survival models revealed that higher levels of and more positive changes in perceived control were associated with longer survival times, independent of sociodemographic correlates. We found that level effects of control were accounted for by well-being and health factors, whereas the change effects of control were not. Analyses also indicated an age-differential pattern, with the predictive effects of both levels and trajectories of control declining in old age. We discuss possible pathways through which perceived control operates to facilitate key health outcomes and consider how their malleability and effectiveness may change with increasing age.

Substantial changes in mastery perceptions of dementia caregivers with the placement of a care recipient.

PubMed

Infurna, Frank J; Gerstorf, Denis; Zarit, Steven H

2013-03-01

The current study examined how a key component of caregiving stress processes, global mastery perceptions, changes with placing the care recipient in a nursing home or institution. We also explored the role of primary stressors in accounting for mastery changes with placement and whether characteristics of the caregiver and care recipient moderate reactions to placement. We applied multiphase growth curve models to prospective longitudinal data from 271 caregivers in the Caregiver Stress and Coping Study who experienced placement of their care recipient. Using a time-to/from-placement metric, we found that caregivers typically experienced declines in mastery preceding placement, followed by a significant increase within 1 year after placement and further increases thereafter. Corresponding changes in primary stressors (role overload) mediated the placement-related increase in mastery. Caregivers who reported more depressive symptoms and activities of daily living/instrumental activities of daily living dependencies of the care recipient were more likely to experience larger placement-related increases in mastery perceptions. Our findings suggest that placement alters psychological resources of caregivers and this effect is driven by corresponding changes in primary stressors. Findings also underscore the importance of examining change processes across salient life events and transitions.

We present results from the OP3 campaign in Sabah during 2008 that allow us to study the impact of local emission changes over Borneo on atmospheric composition at the regional and wider scale. OP3 constituent data provide an important constraint on model performance. Treatment of boundary layer processes is highlighted as an important area of model uncertainty. Model studies of land-use change confirm earlier work, indicating that further changes to intensive oil palm agriculture in South East Asia, and the tropics in general, could have important impacts on air quality, with the biggest factor being the concomitant changes in NOx emissions. With the model scenarios used here, local increases in ozone of around 50 per cent could occur. We also report measurements of short-lived brominated compounds around Sabah suggesting that oceanic (and, especially, coastal) emission sources dominate locally. The concentration of bromine in short-lived halocarbons measured at the surface during OP3 amounted to about 7 ppt, setting an upper limit on the amount of these species that can reach the lower stratosphere.

Discordance between living and death assemblages as evidence for anthropogenic ecological change

PubMed Central

Kidwell, Susan M.

2007-01-01

Mismatches between the composition of a time-averaged death assemblage (dead remains sieved from the upper mixed-zone of the sedimentary column) and the local living community are typically attributed to natural postmortem processes. However, statistical analysis of 73 molluscan data sets from estuaries and lagoons reveals significantly poorer average “live-dead agreement” in settings of documented anthropogenic eutrophication (AE) than in areas where AE and other human impacts are negligible. Taxonomic similarity of paired live and dead species lists declines steadily among areas as a function of AE severity, and, for data sets comprising only adults, rank-order agreement in species abundance drops where AE is suspected. The observed live-dead differences in composition are consistent with eutrophication (anomalous abundance of seagrass-dwellers and/or scarcity of organic-loving species in the death assemblage), suggesting compositional inertia of death assemblages to recent environmental change. Molluscan data sets from open shelf settings (n = 34) also show higher average live-dead discordance in areas of AE. These results indicate that (i) live-dead discordance in surficial grab samples provides valuable evidence for strong anthropogenic modification of benthic communities, (ii) actualistic estimates of the ecological fidelity of molluscan death assemblages tend to be erroneously pessimistic when conducted in nonpristine settings, and (iii) based on their high fidelity in pristine study areas, death assemblages are a promising means of reconstructing otherwise elusive preimpact ecological baselines from sedimentary records.

Multidimensional construct of life satisfaction in older adults in Korea: a six-year follow-up study.

Lim, Hyun Ja; Min, Dae Kee; Thorpe, Lilian; Lee, Chel Hee

2016-11-28

Aging raises wide-ranging issues within social, economic, welfare, and health care systems. Life satisfaction (LS) is regarded as an indicator of quality of life which, in turn, is associated with mortality and morbidity in older adults. The objective of this study was to identify the relevant predictors of life satisfaction and to investigate changes in a multidimensional construct of LS over time. This analysis utilized data from the large-scale, nationally representative Korean Retirement and Income Study (KReIS), a longitudinal survey conducted biennially from 2005 to 2011. Outcome measures were degree of satisfaction with health, economic status, housing, neighbor relationships, and family relationships. GEE models were used to investigate changes in satisfaction within each of the five domains. Of a total 3531 individuals aged 65 or older, 2083 (59%) were women, and the mean age was 72 (s.d = ±6) years. The majority had a spouse (60.8%) and lived in a rural area (58%). Analysis showed that physical and mental health were consistently and significantly associated with satisfaction in each of the domains after adjusting for potential confounders. Living in a rural area and living with a spouse were related to satisfaction with economic, housing, family relationships, and neighbor relationships compared to living in urban areas and living without a spouse; the only outcome that did not show relationship to these predictors was health satisfaction. Female and rural residents reported greater economic satisfaction compared to male and urban residents. Living in an apartment was associated with 1.32 times greater odds of economic satisfaction compared to living in a detached house (95% CI: 1.14-1.53; p < 0.0001). Economic satisfaction was also 1.62 times more likely among individuals living with a spouse compared to single households (95% CI: 1.35-1.96; p < 0.0001). Financial stress index value was found to be a significant predictor of satisfaction with family relationships. Our study indicates that a single domain of LS or overall LS will miss many important aspects of LS as age-related LS is multi-faceted and complicated. While most studies focus on overall life satisfaction, considering life satisfaction as multidimensional is essential to gaining a complete picture.

Features of the urban neighbourhood influence the physical, social and mental wellbeing of residents and communities. We explored the longitudinal association between change to the neighbourhood built environment and the wellbeing of local residents in deprived areas of Glasgow, Scotland. A cohort of residents (n = 365; mean age 50 years; 44% male; 4.1% of the 9000 mailed surveys at baseline) responded to a postal survey in 2005 and 2013. Wellbeing was assessed with the mental (MCS-8) and physical (PCS-8) components of the SF-8 scale. We developed software to aid identification of visible changes in satellite imagery occurring over time. We then used a Geographical Information System to calculate the percentage change in the built environment occurring within an 800 m buffer of each participant's home. The median change in the neighbourhood built environment was 3% (interquartile range 6%). In the whole sample, physical wellbeing declined by 1.5 units on average, and mental wellbeing increased by 0.9 units, over time. In multivariable linear regression analyses, participants living in neighbourhoods with a greater amount of change in the built environment (unit change = 1%) experienced significantly reduced physical (PCS-8: -0.13, 95% CI -0.26 to 0.00) and mental (MCS-8: -0.16, 95% CI -0.31 to - 0.02) wellbeing over time compared to those living in neighbourhoods with less change. For mental wellbeing, a significant interaction by baseline perception of financial strain indicated a larger reduction in those experiencing greater financial strain (MCS-8: -0.22, 95% CI -0.39 to - 0.06). However, this relationship was reversed in those experiencing lower financial strain, whereby living in neighbourhoods with a greater amount of change was associated with significantly improved mental wellbeing over time (MCS-8: 0.38, 95% CI 0.04 to 0.72). Overall, we found some evidence that living in neighbourhoods experiencing higher levels of physical change worsened wellbeing in local residents. However, we found a stronger negative relationship in those with lower financial security and a positive relationship in those with higher financial security. This is one of few studies exploring the longitudinal relationship between the environment and health.

If times change, should we throw away the hearthstone? Exploring (Dis) continuities in autonomy and decision-making in the lives of Ghanaian women

This paper attempts to investigate continuities and discontinuities between traditional and modern representations of womanhood and female gender roles focusing primarily on family and work settings. Using approaches informed by Sociology, Cultural Psychology, and African Studies, the paper explores traditional views of womanhood encapsulated in (and also transmitted intergenerationally) through proverbs. This customary perspective is contrasted with the results of the Everyday Lives Survey from the Pathways of Women's Empowerment Ghana project. The survey investigated the nature of everyday life– education, work, decision making, access to institutions, and autonomy in relationships—in six hundred (600) adult women in both rural and urban communities in three regions of Ghana. We argue that although the times are changing, there have only been modest disruptions in the lives of Ghanaian women as far as issues of autonomy and decision-making in are concerned. PMID:25506334

Objectives The misuse and abuse of prescription opioids (POs) is an epidemic in the USA today. Many states have implemented legislation to curb the use of POs resulting from inappropriate prescribing. Indiana legislated opioid prescribing rules that went into effect in December 2013. The rules changed how chronic pain is managed by healthcare providers. This qualitative study aims to evaluate the impact of Indiana’s opioid prescription legislation on the patient experiences around pain management. Setting This is a qualitative study using interviews of patient and primary care providers to obtain triangulated data sources. The patients were recruited from an integrated pain clinic to which chronic pain patients were referred from federally qualified health clinics (FQHCs). The primacy care providers were recruited from the same FQHCs. The study used inductive, emergent thematic analysis. Participants Nine patient participants and five primary care providers were included in the study. Results Living with chronic pain is disruptive to patients’ lives on multiple dimensions. The established pain management practices were disrupted by the change in prescription rules. Patient–provider relationships, which involve power dynamics and decision making, shifted significantly in parallel to the rule change. Conclusions As a result of the changes in pain management practice, some patients experienced significant challenges. Further studies into the magnitude of this change are necessary. In addition, exploring methods for regulating prescribing while assuring adequate access to pain management is crucial. PMID:29133312

2013-04-01

Loss of friendship post-onset of aphasia is well documented, with reduced social network size and social isolation commonly reported. Because friendship has strong links to psychological well-being and health, increased knowledge about friendships of individuals with aphasia will have important clinical implications. This study aimed to explore the perspectives of 25 community dwelling individuals with chronic aphasia on the role of friendship in living successfully with aphasia. Thematic analysis of transcripts from semi-structured in-depth interviews revealed three over-arching themes relating to the role of friendship in participants' experience of life with aphasia: living with changes in friendships, good times together and support from friends, and the importance of stroke and aphasia friends. Overall, findings highlighted the valued role of friendship in living successfully with aphasia, while also providing evidence of how friendships change and evolve in both negative and positive ways following onset of aphasia. Clinicians are challenged to work creatively to address the role of friendship in life post-stroke in partnership with individuals with aphasia, their families, and friends.

The objective of this study was to describe health-related images and concepts among adolescents living in rural areas of Brazil, using photography. This was a qualitative community-based participatory study that used the photovoice method for data collection with groups of teenagers. Over a four-month period, 26 participants identified health problems in the rural community, took photographs, and reflected critically on the local reality. The adolescents presented pictures and stories that they organized into research themes and categories, representing inadequate living conditions for appropriate socioeconomic and cultural development and limiting the opportunities for change in this community. The study proved to be a positive health education strategy, involving young people in the community's health and maximizing the voice of teenagers as protagonists in their own history.

In this paper we introduce new methodology for the observation of living biological samples in an environmental scanning electron microscope (ESEM). The methodology is based on an unconventional initiation procedure for ESEM chamber pumping, free from purge-flood cycles, and on the ability to control thermodynamic processes close to the sample. The gradual and gentle change of the working environment from air to water vapor enables the study of not only living samples in dynamic in situ experiments and their manifestation of life (sample walking) but also its experimentally stimulated physiological reactions. Moreover, Monte Carlo simulations of primary electron beam energy losses in a water layer on the sample surface were studied; consequently, the influence of the water thickness on radiation, temperature, or chemical damage of the sample was considered.

The purpose of this study was to understand the value and impact of the Veteran-Directed Home and Community Based Services program (VD-HCBS) on Veterans' lives in their own voices. Focus groups and individual interviews by telephone were conducted to elicit participant perspectives on what was most meaningful, and what difference VD-HCBS made in their lives. Transcripts were analyzed using content analysis. The sample included 21 Veterans, with a mean age of 66±14, enrolled in VD-HCBS an average of 20.8 months. All were at risk of institutional placement based on their level of disability. Five major categories captured the information provided by participants: What a Difference Choice Makes; I'm a Person!; It's a Home-Saver; Coming Back to Life; and Keeping Me Healthy & Safe. Participants described the program as life changing. This study is the first time that Veterans themselves have identified the ways in which VD-HCBS impacted their lives, uncovering the mechanisms underlying positive outcomes. These categories revealed new ways of understanding VD-HCBS as an innovative approach to meeting the person-centered needs of Veterans wishing to remain at home, while experiencing quality care and leading meaningful lives, areas identified as priorities for improving long term services and supports.

Pulmonary complications, respiratory symptoms and depression are common occurrences which contribute to the morbidity and mortality seen in individuals living with HIV/AIDS. This study investigated the effect of aerobic exercise on the pulmonary functions, respiratory symptoms and psychological status of people living with HIV. This study was conducted in Lagos, Nigeria from October 2014 to May 2015. Forty eligible individuals with HIV aged 18 yr and above participated, of which 33 cooperated to the end. They were recruited from the HIV/AIDS Prevention and Intervention Initiative (APIN) Clinic, Lagos University Teaching Hospital, Nigeria and were randomly assigned to either the study or the control group. The study group received aerobic exercise training three times a week for six weeks and counselling while the control group received only counselling. Pulmonary functions, respiratory symptoms and psychological status were evaluated at baseline and at six weeks. Inferential statistics of paired and independent t-test were used to analyse the data. Comparison of mean changes in the pulmonary variables of the study group with those of the control group showed significant differences in all but in the respiratory rate (RR) - [Forced Expiratory Volume in one second: P=0.001, Forced Vital Capacity: P=0.001, Peak Expiratory Flow: P=0.001]. There were also significant differences between the mean changes in respiratory symptoms (P=0.001) and depressive symptoms (P=0.001) of study group and those of the control group. Aerobic exercise training significantly improved pulmonary functions as well as significantly reduced respiratory and depressive symptoms in people living with HIV.

Indonesia's maritime continent is one of the most vulnerable regions regarding to climate change impacts. One of the vulnerable areas affected are the urban areas, because they are home to almost half of Indonesia's population where they live and earn a living, so that environmental management efforts need to be done. To support such efforts, climate change analysis is required. The analysis was carried out in several big cities in Indonesia. The method used in the research was trend analysis of temperature, rainfall, shifts in rainfall patterns, and extreme climatic trend. The data of rainfall and temperature were obtained from Meteorology and Geophysics Agency (BMKG). The result shows that the air temperature and rainfall have a positive trend, except in Semarang City which having a negative rainfall trend. The result also shows heavy rainfall trends. These indicate that climate is changing in these three cities.

Probe electrospray ionization (PESI) is a recently developed ESI-based ionization technique which generates electrospray from the tip of a solid needle. In this study, we have applied PESI interfaced with a time of flight mass spectrometer (TOF-MS) for direct profiling of phytochemicals in a section of a tulip bulb in different regions, including basal plate, outer and inner rims of scale, flower bud and foliage leaves. Different parts of tulip petals and leaves have also been investigated. Carbohydrates, amino acids and other phytochemicals were detected. A series of in vivo PESI-MS experiments were carried out on the second outermost scales of four living tulip bulbs to monitoring the change of carbohydrate content during the first week of initial growth. The breakdown of carbohydrates was observed which was in accordance with previous reports achieved by other techniques. This study has indicated that PESI-MS can be used for rapid and direct analysis of phytochemicals in living biological systems with advantages of low sample consumption and little sample preparation. Therefore, PESI-MS can be a new choice for direct analysis/profiling of bioactive compounds or monitoring metabolic changes in living biological systems.

Manoeuvring between anxiety and control: patients' experience of learning to live with diabetes: a lifeworld phenomenological study.

2015-01-01

Research shows that people with diabetes want their lives to proceed as normally as possible, but some patients experience difficulty in reaching their desired goals with treatment. The learning process is a complex phenomenon interwoven into every facet of life. Patients and healthcare providers often have different perspectives in care which gives different expectations on what the patients need to learn and cope with. The aim of this study, therefore, is to describe the experience of learning to live with diabetes. Interviews were conducted with 12 patients afflicted with type 1 or type 2 diabetes. The interviews were then analysed with reference to the reflective lifeworld research approach. The analysis shows that when the afflicted realize that their bodies undergo changes and that blood sugar levels are not always balanced as earlier in life, they can adjust to their new conditions early. The afflicted must take responsibility for balancing their blood sugar levels and incorporating the illness into their lives. Achieving such goals necessitates knowledge. The search for knowledge and sensitivity to changes are constant requirements for people with diabetes. Learning is driven by the tension caused by the need for and dependence on safe blood sugar control, the fear of losing such control, and the fear of future complications. The most important responsibilities for these patients are aspiring to understand their bodies as lived bodies, ensuring safety and security, and acquiring the knowledge essential to making conscious choices.

Learning turning points—in life with long-term illness—visualized with the help of the life-world philosophy

2014-01-01

A long-term illness is an occurrence that changes one's life and generates a need to learn how to live with it. This article is based on an empirical study of interviews on people living with different long-term illnesses. The results have shown that the learning process is a complex phenomenon interwoven with life as a whole. The essential meaning of learning to live with long-term illness concerns a movement toward a change of understanding of access to the world. In this movement, in which everyday lives as well as relationships with oneself and others are affected, a continual renegotiation is needed. Texts from existential/lifeworld philosopher, Heidegger and Gadamer, have been used to get a greater understanding of the empirical results. These texts have been analysed with particular focus on learning turning points and the importance of reflection. The results are highlighted under the following themes: Pursuit of balance—the aim of learning, The tense grip—the resistance to learning, To live more really—the possibilities of the learning, Distancing—the how of the learning, and The tense of the learning—the whole of the learning. In those learning turning points are present. Knowledge from this study has been used to make a didactic model designed to give caregivers a tool to support patients’ learning. The didactic model is called: The challenge to take charge of life with a long-term illness. PMID:24559547

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

If you look between the middle and the top of the ball of rock on which we all live, the very excited part of the top air (as high as where the space-house flies) doesn't change much on a normal day. In fact, it is very much the same in every direction. However, sometimes when there is sudden, heavy wind from the sun, the excited top air can be different and changing, becoming more or less filled up, in many directions---especially if you look at toward the top and the right of the ball of rock on which we all live. Some of the excited top air becomes suddenly filled up in one big area. Near there, there are also parts of the the excited top air that start changing in many very small places. These small changing areas sometimes make it hard to talk between space and the ground. We studied this happening on days on and around day 17 of third month of 2015 when the wind from the sun hit the ball of rock on which we all live very hard. We used things that talk from space to the ground in an area around school up to several hundred 5280 feet away. We made pictures of the changing excited top air, especially the small changing places, and looked for when they did and didn't make for good talking from space to the ground. We studied these pictures to learn when and why this sometimes happens and sometimes it doesn't. We are excited to share what we learned with you.

Fluorescence pH imaging in living cells is a rapidly expanding research direction, however, it relies on the development of pH-sensitive fluorescent imaging agents. Here four norcyanine dyes with benzo[c,d]indolium moiety, exhibiting high spectral sensitivity with pH changes, were synthesized for fluorescence pH imaging in living cells, and characterized by 1 H NMR, 13 C NMR, IR, UV-Vis and HRMS. The investigation of their spectral properties in methanol and water showed that the absorption and emission maxima were in the region 488-618nm and 583-651nm, respectively, and four dyes exhibited high photostability. The pH spectral titrations showed that selective dye D1 had pH-dependent absorption spectral changes within the pH range of 2.4 to 9.4, and high fluorescent spectral sensitivity at pH5.0-8.0, with a pK a of 5.0. A cell association study indicated that dye D1 exhibited no or mild cytotoxicity at the application dose and duration, and could be accumulated in cells and mainly distributed in the cytoplasm, giving red fluorescence imaging. In particular, dye D1 could achieve pH-dependent fluorescence imaging in living cells with the increase of pH from 3.0 to 8.0, at excitation wavelength of 543nm and receiving wavelength of 655-755nm, which was valuable for studying the weak acidic, neutral and weak alkaline biological tissue compartments.

The adaptation of polar fishes to climatic changes: Structure, function and phylogeny of haemoglobin.

PubMed

Verde, Cinzia; Giordano, Daniela; di Prisco, Guido

2008-01-01

In the Antarctic, fishes of dominant suborder Notothenioidei have evolved in a unique thermal scenario. Phylogenetically related taxa of the suborder live in a wide range of latitudes, in Antarctic, sub-Antarctic and temperate oceans. Consequently, they offer a remarkable opportunity to study the physiological and biochemical characters gained and, conversely, lost during their evolutionary history. The evolutionary perspective has also been pursued by comparative studies of some features of the heme protein devoted to O(2) transport in fish living in the other polar region, the Arctic. The two polar regions differ by age and isolation. Fish living in each habitat have undergone regional constraints and fit into different evolutionary histories. The aim of this contribution is to survey the current knowledge of molecular structure, functional features, phylogeny and adaptations of the haemoglobins of fish thriving in the Antarctic, sub-Antarctic and Arctic regions (with some excursions in the temperate latitudes), in search of insights into the convergent processes evolved in response to cooling. Current climate change may disturb adaptation, calling for strategies aimed at neutralising threats to biodiversity.

The meaning of widowhood and health to older middle-class Hindu widows living in a South Indian community.

2010-10-01

Indian widowhood has long been associated with victimization and vulnerability, but traditional attitudes toward widowhood are changing and reflect the rapid changes occurring in India. Using Caring Inquiry, a phenomenological-hermeneutic methodology that places caring at its center, this article presents a study that explores the meaning of health and widowhood to 14 older middle-class Hindu widows living in urban South India. From the data emerge six metathemes that are pertinent to nursing praxis and the delivery of health care to widows in South India: (a) Drawing From Within, (b) Seeking Help and Guidance, (c) Accepting the Role, (d) Challenging Tradition, (e) Serving Others, and (f) Finding Companionship. The findings reveal that all the widows share a common desire to move on with life, articulated by one widow as "The Show Must Go On," which serves as a foundation for a theory and model of the meaning of widowhood and health to older middle-class South Indian Hindu widows. This study advances the limited body of knowledge on the lives and health of these widows.

Adaptation in Living Systems

Tu, Yuhai; Rappel, Wouter-Jan

2018-03-01

Adaptation refers to the biological phenomenon where living systems change their internal states in response to changes in their environments in order to maintain certain key functions critical for their survival and fitness. Adaptation is one of the most ubiquitous and arguably one of the most fundamental properties of living systems. It occurs throughout all biological scales, from adaptation of populations of species over evolutionary time to adaptation of a single cell to different environmental stresses during its life span. In this article, we review some of the recent progress made in understanding molecular mechanisms of cellular-level adaptation. We take the minimalist (or the physicist) approach and study the simplest systems that exhibit generic adaptive behaviors, namely chemotaxis in bacterium cells (Escherichia coli) and eukaryotic cells (Dictyostelium). We focus on understanding the basic biochemical interaction networks that are responsible for adaptation dynamics. By combining theoretical modeling with quantitative experimentation, we demonstrate universal features in adaptation as well as important differences in different cellular systems. Future work in extending the modeling framework to study adaptation in more complex systems such as sensory neurons is also discussed.

This article examines the growing social phenomenon of elderly people living alone from 2 points of view: the objective loneliness of living alone and the subjective loneliness of feeling lonely. To validate the UCLA loneliness scale as a tool for the overall measurement of loneliness and to determine the social profile in elderly people living alone. Observational study carried out over 2 years (2012-2013) to identify elderly people living alone; case-control study to validate the UCLA loneliness scale. The sample was taken from 3 surgeries belonging to 2 Primary Care health centres from urban and rural areas. We studied construct validity, discriminant validity and sensitivity analysis were analysed. Of the elderly population studied 22.3% live alone, 61.7% due to loss of spouse, with a mean age of 70.7 years, and 82.7% women; 17.3% have no family ties and 63.2% feel lonely. UCLA loneliness scale has a construct validity with a high correlation between items. The discriminant validity was confirmed in relation to the elderly who do not live alone, with Cronbach alpha of 0.95, and it is sensitive to change. One in 4-5 elderly live alone, mainly due to the loss of spouse. There are 3 times as many women as men who live alone. Two out of 3 experience the feeling of loneliness. The UCLA loneliness scale has proved to be a useful and sensitive tool to measure loneliness in the elderly population. Copyright © 2015 Sociedad Española de Médicos de Atención Primaria (SEMERGEN).

Mental health nursing consistently emerges as less popular than other specialties, and both service users and mental health practitioners are affected by negative attitudes. Education is fundamental to attracting students to the field of mental health nursing. The aim of this study was to determine the impact of undergraduate mental health curricula on student attitudes to people with mental illness, and career interest in mental health nursing. A traditional mental health course was compared to a course delivered by a person with lived experience of mental illness (and mental health service use) for its impact on student attitudes and career intentions in mental health nursing (cohort 1: n = 70, cohort 2: n = 131, respectively). In both cohorts, attitudes were measured via self-report, before and after the course, and changes were investigated through within-subjects t-tests. The lived experience-led course demonstrated statistically-significant positive changes in intentions to pursue mental health nursing and a decrease in negative stereotypes, which were not observed in the traditional course. The valuable contribution of mental health nursing emerged in the traditional, but not lived-experience-led, programmes. These findings support the value of an academic with lived experience of mental health challenges in promoting attraction to mental health nursing as a career option. © 2014 Australian College of Mental Health Nurses Inc.

Assisted living: a place to manage uncertainty. The ambiguity of assisted living is unavoidable because residents' needs are always changing. The Wheat Valley example is used to examine this concept.

Ekerdt, David J

2005-01-01

The assisted living environment lacks the satisfying clarity of the consumer model (a stay at the Holiday Inn) or the medical model (the hospital or nursing home). Yet the ambiguity of assisted living is unavoidable because it shelters individuals whose needs are changing, the model of care requires extensive negotiation with residents, and staff members must continually compromise as they implement the principles. Assisted living is a place where uncertainty is managed, not resolved. This indicates a need for the further pursuit of qualitative research, such as reported by these articles and others (e.g., Carder, 2002), to explore how participants construct, make sense of, and interpret their daily experience in assisted living.

The future health costs associated with predicted climate change-related events such as hurricanes, heat waves, and floods are projected to be enormous. This article estimates the health costs associated with six climate change-related events that struck the United States between 2000 and 2009. The six case studies came from categories of climate change-related events projected to worsen with continued global warming-ozone pollution, heat waves, hurricanes, infectious disease outbreaks, river flooding, and wildfires. We estimate that the health costs exceeded $14 billion, with 95 percent due to the value of lives lost prematurely. Actual health care costs were an estimated $740 million. This reflects more than 760,000 encounters with the health care system. Our analysis provides scientists and policy makers with a methodology to use in estimating future health costs related to climate change and highlights the growing need for public health preparedness.

Heart transplantation experiences: a phenomenological approach.

PubMed

Sadala, Maria Lúcia Araújo; Stolf, Noedir Antônio Groppo

2008-04-01

The aim of this study was to understand the heart transplantation experience based on patients' descriptions. To patients with heart failure, heart transplantation represents a possibility to survive and improve their quality of life. Studies have shown that more quality of life is related to patients' increasing awareness and participation in the work of the healthcare team in the post-transplantation period. Deficient relationships between patients and healthcare providers result in lower compliance with the postoperative regimen. A phenomenological approach was used to interview 26 patients who were heart transplant recipients. Patients were interviewed individually and asked this single question: What does the experience of being heart transplanted mean? Participants' descriptions were analysed using phenomenological reduction, analysis and interpretation. Three categories emerged from data analysis: (i) the time lived by the heart recipient; (ii) donors, family and caregivers and (iii) reflections on the experience lived. Living after heart transplant means living in a complex situation: recipients are confronted with lifelong immunosuppressive therapy associated with many side-effects. Some felt healthy whereas others reported persistence of complications as well as the onset of other pathologies. However, all participants celebrated an improvement in quality of life. Health caregivers, their social and family support had been essential for their struggle. Participants realised that life after heart transplantation was a continuing process demanding support and structured follow-up for the rest of their lives. The findings suggest that each individual has unique experiences of the heart transplantation process. To go on living participants had to accept changes and adapt: to the organ change, to complications resulting from rejection of the organ, to lots of pills and food restrictions. Stimulating a heart transplant patients spontaneous expression about what they are experiencing and granting them the actual status of the main character in their own story is important to their care.

Mental health service providers across Australia, including Western Australia (WA), have begun to offer individualised funds, shared management, person-centred and self-directed (SPS) services. No research exists on the impact of SPS services on the lived experiences of these particular consumers. This study explored the impact of a SPS service offered for the first time in WA to consumers with mental illness. Data on sixteen consumers' lived experiences were analysed using an abbreviated grounded theory approach. These data had been developed by the consumers, Guides (staff) and an independent evaluator, and most of it had been collected in the past prior to the commencement of the study. Three over-arching categories, and related subcategories, emerged indicating that 1) access to individualised funds enabled practical and psychological benefits to consumers; 2) consistent contact in shared management and person-centred relationships enhanced the provision of timely and meaningful staff support to consumers; and 3) high quality shared management and person-centred relationships with staff and the opportunity to self-direct enabled consumers' change and growth. SPS services enhanced consumers' lived experiences and enabled staff to provide and consumers to experience timely access to recovery resources, consistent contact, responsive and high quality support, and self-direction of services. In this, consumers changed, grew and achieved desired recovery experiences. The overall impact of the SPS service seemed to be founded on the goodness of fit between person characteristics of staff and consumers, which enabled rich support that provided for corrective emotional experiences. This enabled consumers to build meaningful and hopeful lives where they started to live with, and beyond, their mental illness.

Transcriptome analysis of a long-lived natural Drosophila variant: a prominent role of stress- and reproduction-genes in lifespan extension

PubMed Central

2012-01-01

Background While studying long-lived mutants has advanced our understanding of the processes involved in ageing, the mechanisms underlying natural variation in lifespan and ageing rate remain largely unknown. Here, we characterise genome-wide expression patterns of a long-lived, natural variant of Drosophila melanogaster resulting from selection for starvation resistance (SR) and compare it with normal-lived control flies (C). We do this at two time points representing middle age (90% survival) and old age (10% survival) respectively, in three adult diets (malnutrition, optimal food, and overfeeding). Results We found profound differences between Drosophila lines in their age-related expression. Most of the age-associated changes in normal-lived flies were abrogated in long-lived Drosophila. The stress-related genes, including those involved in proteolysis and cytochrome P450, were generally higher expressed in SR flies and showed a smaller increase in expression with age compared to C flies. The genes involved in reproduction showed a lower expression in middle-aged SR than in C flies and, unlike C flies, a lack of their downregulation with age. Further, we found that malnutrition strongly affected age-associated transcript patterns overriding the differences between the lines. However, under less stressful dietary conditions, line and diet affected age-dependent expression similarly. Finally, we present lists of candidate markers of ageing and lifespan extension. Conclusions Our study unveils transcriptional changes associated with lifespan extension in SR Drosophila. The results suggest that natural genetic variation for SR and lifespan can operate through similar transcriptional mechanisms as those of dietary restriction and life-extending mutations.

Chinese individuals who have immigrated to a Western country initially tend to have a lower risk of cardiovascular disease (CVD) compared to people who are already living there. Some studies have found, however, that CVD risk increases over time in immigrants and that immigration to a western country is associated with changes in dietary patterns. This could have unfavourable effects on the risk of CVD. There is limited knowledge on the food patterns, awareness and knowledge about healthy nutrition among Chinese immigrants. The objective for this study is to explore changes in food patterns, and levels of awareness and knowledge of healthy nutrition by length of residence among Chinese immigrants to Canada. 120 Chinese individuals born in China but currently living in Canada completed an assessment on socio-demographic characteristics, changes in dietary patterns and variables of awareness and knowledge about healthy foods. With ordinal logistic regression the associations between the quartiles of length of residence and dietary patterns, variables of awareness and knowledge about healthy foods were explored, adjusting for age, sex, education and body mass index. More than 50% of the participants reported increasing consumption of fruits and vegetables, decreasing the use of deep-frying after immigration. Increased awareness and knowledge about healthy foods was reported by more than 50% of the participants. Ordinal regression indicated that Chinese immigrants who lived in Canada the longest, compared to Chinese immigrants who lived in Canada the shortest, consumed significant greater portion sizes (OR: 9.9; 95% CI: 3.11 - 31.15), dined out more frequently (OR: 15.8; 95% CI: 5.0 - 49.85), and consumed convenience foods more often (OR: 3.5; 95% CI: 1.23 - 10.01). Chinese immigrants reported some favourable changes in their dietary intake and greater awareness and more knowledge about healthy foods after immigration. However, an increase in portion size, an increased frequency of dining out and an increased consumption of convenience foods could indicate some unfavourable changes. These results suggest that health promotion strategies should build on the observed benefits of improved nutritional knowledge and target areas of portion size and convenience eating.

Landscape structure and live fences in Andes Colombian agrosystems: upper basin of the Cane-Iguaque River.

PubMed

Otero, Javier; Onaindia, Miren

2009-12-01

Changes in land use have generated a new landscape configuration in the Andino orobiome (mountain range) of the tropical Andes, resulting in a mosaic of cultivation and pastures interrupted by small fragments of forest and live fences. This has resulted in an ongoing decrease in the biodiversity of this biome. In the upper basin of the Cane-Iguaque River (Villa de Levya-Boyacá, Colombia), located 2,600-3,000 m above the Cordillera Oriental, over three time periods in 1960, 1984, and 2004, we characterized the structure, patterns, and evolution of the overall landscape and of the live fences (used as tools in biodiversity conservation and considered to be desirable alternatives to nonlive fences in farming production systems) within an agricultural landscape. To do this, we interpreted high-resolution satellite images using a landscape ecology approach and applied landscape map metrics. We found that the natural forests have been transformed by pastures and cultivation, and that although live fences cover only a small portion of the total landscape (4.6%), they have an important effect on landscape structure and biodiversity. There has been an increase in live fences, especially between 1960 and 1984, as well as an increase in their density. However, there has been a reduction in the average length of live fences over the periods that we studied. This could be due in part to changes in the types of agricultural products that have been cultivated in recent years, with an increase in potatoes and a decrease in other vegetables, and also by resource extraction of timber and fuel wood. In the studied area, agricultural production was sustained while biodiversity conservation was improved by the use of live fences. Therefore, live fences should be considered not only as part of an agriculturally productive area, but also as an important element of a multi-functional landscape that contributes to the maintenance of biodiversity and provides resources of economic and ecological interest, decreasing the pressure on natural forest. Improving the network of live fences constitutes an important strategy for the sustainable management of the rural landscape of the Andino orobiome of Colombia and similar areas in the tropics.

Animal-Microbial Symbioses in Changing Environments

PubMed Central

Carey, Hannah V.; Duddleston, Khrystyne N.

2014-01-01

The environments in which animals have evolved and live have profound effects on all aspects of their biology. Predictable rhythmic changes in the physical environment are arguably among the most important forces shaping the evolution of behavior and physiology of animals, and to anticipate and prepare for these predictable changes animals have evolved biological clocks. Unpredictable changes in the physical environment have important impacts on animal biology as well. The ability of animals to cope with and survive unpredictable perturbations depends on phenotypic plasticity and/or microevolution. From the time metazoans first evolved from their protistan ancestors they have lived in close association with a diverse array of microbes that have influenced, in some way, all aspects of the evolution of animal structure, function and behavior. Yet, few studies have addressed whether daily or seasonal rhythms may affect, or be affected by, an animal’s microbial symbionts. This survey highlights how biologists interested in the ecological and evolutionary physiology of animals whose lifestyles are influenced by environmental cycles may benefit from considering whether symbiotic microbes have shaped the features they study.

"No place like home": Aging in post-reform Beijing.

Yu, Jie; Rosenberg, Mark W

2017-07-01

This study shows the Western theorization and interpretation of aging, place and health are not well suited to a non-western case. The current generation of older Chinese has experienced the transition from a planned economy to a socialist market economy. Urban changes have taken place in various ways. This study explains the spatio-temporal processes of older people with their changing places by conducting in-depth interviews with 47 older people living at home in Beijing. Their generational consciousness and old place identities are deeply rooted in pre-reform Collectivism and shaped by socialist ideologies of the past. The representation of the old identity among older people is circumscribed by their living situations and selectively manifested. In most cases, there are limited mechanisms formed to recreate positive place meanings and reintegrate older people and place. The processes reflect the growing social inequality and changing cultural values in a society in transition. Growing social inequality and changing cultural values have a great impact on older people's health and well-being. Copyright © 2017 Elsevier Ltd. All rights reserved.

To assess the effectiveness of intratissue refractive index shaping (IRIS) in living corneas and test the hypothesis that it can be enhanced by increasing the two-photon absorption (TPA) of the tissue. Three corneas were removed from adult cats and cut into six pieces, which were placed in preservative (Optisol-GS; Bausch & Lomb, Inc., Irvine, CA) containing 0%, 0.25%, 1%, 1.5%, or 2.5% sodium fluorescein (Na-Fl). An 800-nm Ti:Sapphire femtosecond laser with a 100-fs pulse duration and 80-MHz repetition rate was used to perform IRIS in each piece, creating several refractive index (RI) modification lines at different speeds (between 0.1 and 5 mm/s). The lines were 1 mum wide, 10 microm apart, and approximately 150 microm below the tissue surface. The RI change of each grating was measured using calibrated, differential interference contrast microscopy. TUNEL staining was performed to assess whether IRIS or Na-Fl doping causes cell death. Scanning at 0.1 mm/s changed the RI of undoped, living corneas by 0.005. In doped corneas, RI changes between 0.01 and 0.02 were reliably achieved with higher scanning speeds. The magnitude of RI changes attained was directly proportional to Na-Fl doping concentration and inversely proportional to the scanning speed used to create the gratings. IRIS can be efficiently performed in living corneal tissue. Increasing the TPA of the tissue with Na-Fl increased both the scanning speeds and the magnitude of RI changes in a dose-dependent manner. Ongoing studies are exploring the use of IRIS to alter the optical properties of corneal tissue in situ, over an extended period.

Urban living has been shown to affect health in various ways. As the world is becoming more urbanised and almost two-thirds of people with diabetes now live in cities, research into the relationship between urban living, health and diabetes is key to improving the lives of many. The majority of people with diabetes have type 2 diabetes, a subset linked to overweight and obesity, decreased physical activity and unhealthy diets. Diabetes has significant consequences for those living with the condition as well as their families, relationships and wider society. Although care and management are improving, complications remain common, and diabetes is among the leading causes of vision loss, amputation, neuropathy and renal and cardiovascular disease worldwide. We present a research protocol for exploring the drivers of type 2 diabetes and its complications in urban settings through the Cities Changing Diabetes (CCD) partnership programme. A global study protocol is implemented in eight collaborating CCD partner cities. In each city, academic institutions, municipal representatives and local stakeholders collaborate to set research priorities and plan implementation of findings. Local academic teams execute the study following the global study protocol presented here. A quantitative Rule of Halves analysis obtains measures of the magnitude of the diabetes burden, the diagnosis rates in each city and the outcomes of care. A qualitative Diabetes Vulnerability Assessment explores the urban context in vulnerability to type 2 diabetes and identifies social factors and cultural determinants relevant to health, well-being and diabetes. The protocol steers the collection of primary and secondary data across the study sites. Research ethics board approval has been sought and obtained in each site. Findings from each of the local studies as well as the result from combined multisite (global) analyses will be reported in a series of core scientific journal papers. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

Membrane status of boar spermatozoa after cooling or cryopreservation.

PubMed

Maxwell, W M; Johnson, L A

1997-07-15

This study tested the hypothesis that sperm membrane changes during cooling contribute substantially to the membrane damage observed after cryopreservation of boar spermatozoa. Flow cytometry was used to assess viability (percentages of live and dead cells) of boar sperm cells after staining with SYBR-14 and propidium iodide (PI) and acrosome status after staining with FITC-pisum sativum agglutenin and PI. Incubation (38 degrees C, 4 h), cooling (to 15 or 5 degrees C) and freezing reduced the proportion of live spermatozoa compared with those in fresh semen. There were more membrane changes in spermatozoa cooled to 5 degrees C than to 15 degrees C. The proportion of live spermatozoa decreased during processing for cryopreservation and cooling to 5 degrees C, but was unaffected by freezing and thawing if held at 15 degrees C for 3.5 h during cooling. Spermatozoa not held during cooling exhibited further loss of viability after freezing and thawing. Holding the spermatozoa also increased the proportion of acrosome-intact spermatozoa at both 15 degrees C and 5 degrees C and at thawing compared with that of the unheld controls. The results of this study suggest that a substantial proportion of the membrane changes associated with cryopreservation of boar spermatozoa may be attributed to the cooling of the cells to 5 degrees C rather than to the freezing and thawing process, and that sperm membrane changes are reduced when semen is held at 15 degrees C during cooling.

Image acquisition optimization of a limited-angle intrafraction verification (LIVE) system for lung radiotherapy.

PubMed

Zhang, Yawei; Deng, Xinchen; Yin, Fang-Fang; Ren, Lei

2018-01-01

Limited-angle intrafraction verification (LIVE) has been previously developed for four-dimensional (4D) intrafraction target verification either during arc delivery or between three-dimensional (3D)/IMRT beams. Preliminary studies showed that LIVE can accurately estimate the target volume using kV/MV projections acquired over orthogonal view 30° scan angles. Currently, the LIVE imaging acquisition requires slow gantry rotation and is not clinically optimized. The goal of this study is to optimize the image acquisition parameters of LIVE for different patient respiratory periods and gantry rotation speeds for the effective clinical implementation of the system. Limited-angle intrafraction verification imaging acquisition was optimized using a digital anthropomorphic phantom (XCAT) with simulated respiratory periods varying from 3 s to 6 s and gantry rotation speeds varying from 1°/s to 6°/s. LIVE scanning time was optimized by minimizing the number of respiratory cycles needed for the four-dimensional scan, and imaging dose was optimized by minimizing the number of kV and MV projections needed for four-dimensional estimation. The estimation accuracy was evaluated by calculating both the center-of-mass-shift (COMS) and three-dimensional volume-percentage-difference (VPD) between the tumor in estimated images and the ground truth images. The robustness of LIVE was evaluated with varied respiratory patterns, tumor sizes, and tumor locations in XCAT simulation. A dynamic thoracic phantom (CIRS) was used to further validate the optimized imaging schemes from XCAT study with changes of respiratory patterns, tumor sizes, and imaging scanning directions. Respiratory periods, gantry rotation speeds, number of respiratory cycles scanned and number of kV/MV projections acquired were all positively correlated with the estimation accuracy of LIVE. Faster gantry rotation speed or longer respiratory period allowed less respiratory cycles to be scanned and less kV/MV projections to be acquired to estimate the target volume accurately. Regarding the scanning time minimization, for patient respiratory periods of 3-4 s, gantry rotation speeds of 1°/s, 2°/s, 3-6°/s required scanning of five, four, and three respiratory cycles, respectively. For patient respiratory periods of 5-6 s, the corresponding respiratory cycles required in the scan changed to four, three, and two cycles, respectively. Regarding the imaging dose minimization, for patient respiratory periods of 3-4 s, gantry rotation speeds of 1°/s, 2-4°/s, 5-6°/s required acquiring of 7, 5, 4 kV and MV projections, respectively. For patient respiratory periods of 5-6 s, 5 kV and 5 MV projections are sufficient for all gantry rotation speeds. The optimized LIVE system was robust against breathing pattern, tumor size and tumor location changes. In the CIRS study, the optimized LIVE system achieved the average center-of-mass-shift (COMS)/volume-percentage-difference (VPD) of 0.3 ± 0.1 mm/7.7 ± 2.0% for the scanning time priority case, 0.2 ± 0.1 mm/6.1 ± 1.2% for the imaging dose priority case, respectively, among all gantry rotation speeds tested. LIVE was robust against different scanning directions investigated. The LIVE system has been preliminarily optimized for different patient respiratory periods and treatment gantry rotation speeds using digital and physical phantoms. The optimized imaging parameters, including number of respiratory cycles scanned and kV/MV projection numbers acquired, provide guidelines for optimizing the scanning time and imaging dose of the LIVE system for its future evaluations and clinical implementations through patient studies. © 2017 American Association of Physicists in Medicine.

Studies on living donors from the donors' perspective show that the donation process involves both positive and negative feelings involving vulnerability. Qualitative studies of living kidney, liver, and allogeneic hematopoietic stem cell donors have not previously been merged in the same analysis. Therefore, our aim was to synthesize current knowledge of these donors' experiences to deepen understanding of the meaning of being a living donor for the purpose of saving or extending someone's life. The meta-ethnography steps presented by Noblit and Hare in 1988 were used. Forty-one qualitative studies from 1968 to 2016 that fulfilled the inclusion criteria were analyzed. The studies comprised experiences of over 670 donors. The time since donation varied from 2 days to 29 years. A majority of the studies, 25 of 41, were on living kidney donors. The synthesis revealed that the essential meaning of being a donor is doing what one feels one has to do, involving 6 themes; A sense of responsibility, loneliness and abandonment, suffering, pride and gratitude, a sense of togetherness, and a life changing event. The main issue is that one donates irrespective of what one donates. The relationship to the recipient determines the motives for donation. The deeper insight into the donors' experiences provides implications for their psychological care.

Longitudinal evaluation of dementia care in German nursing homes: the “DemenzMonitor” study protocol

PubMed Central

2013-01-01

Background In Germany, the number of people with dementia living in nursing homes is rapidly increasing. Providing adequate care for their special needs is a challenge for institutions and their staff members. Because of the growing number of people with dementia, changes to the conceptual orientation of nursing homes have occurred. These changes include specialized living arrangements and psychosocial interventions recommended for people with dementia. Until now, the provision of dementia care and its association to the residents’ behavior and quality of life is not well investigated in Germany. The purpose of this study is to describe the provision of dementia care and to identify resident- as well as facility-related factors associated with residents behavior and quality of life. Methods/Design The DemenzMonitor study is designed as a longitudinal study that is repeated annually. Data will be derived from a convenience sample consisting of nursing homes across Germany. For the data collection, three questionnaires have been developed that measure information on the level of the nursing home, the living units, and the residents. Data collection will be performed by staff members from the nursing homes. The data collection procedure will be supervised by a study coordinator who is trained by the research team. Data analysis will be performed on each data level using appropriate techniques for descriptions and comparisons as well as longitudinal regression analysis. Discussion The DemenzMonitor is the first study in Germany that assesses how dementia care is provided in nursing homes with respect to living arrangements and recommended interventions. This study links the acquired data with residents’ outcome measurements, making it possible to evaluate different aspects and concepts of care. PMID:24237990

Parasites Affect Food Web Structure Primarily through Increased Diversity and Complexity

Comparative research on food web structure has revealed generalities in trophic organization, produced simple models, and allowed assessment of robustness to species loss. These studies have mostly focused on free-living species. Recent research has suggested that inclusion of parasites alters structure. We assess whether such changes in network structure result from unique roles and traits of parasites or from changes to diversity and complexity. We analyzed seven highly resolved food webs that include metazoan parasite data. Our analyses show that adding parasites usually increases link density and connectance (simple measures of complexity), particularly when including concomitant links (links from predators to parasites of their prey). However, we clarify prior claims that parasites “dominate” food web links. Although parasites can be involved in a majority of links, in most cases classic predation links outnumber classic parasitism links. Regarding network structure, observed changes in degree distributions, 14 commonly studied metrics, and link probabilities are consistent with scale-dependent changes in structure associated with changes in diversity and complexity. Parasite and free-living species thus have similar effects on these aspects of structure. However, two changes point to unique roles of parasites. First, adding parasites and concomitant links strongly alters the frequency of most motifs of interactions among three taxa, reflecting parasites' roles as resources for predators of their hosts, driven by trophic intimacy with their hosts. Second, compared to free-living consumers, many parasites' feeding niches appear broader and less contiguous, which may reflect complex life cycles and small body sizes. This study provides new insights about generic versus unique impacts of parasites on food web structure, extends the generality of food web theory, gives a more rigorous framework for assessing the impact of any species on trophic organization, identifies limitations of current food web models, and provides direction for future structural and dynamical models.

Comparative research on food web structure has revealed generalities in trophic organization, produced simple models, and allowed assessment of robustness to species loss. These studies have mostly focused on free-living species. Recent research has suggested that inclusion of parasites alters structure. We assess whether such changes in network structure result from unique roles and traits of parasites or from changes to diversity and complexity. We analyzed seven highly resolved food webs that include metazoan parasite data. Our analyses show that adding parasites usually increases link density and connectance (simple measures of complexity), particularly when including concomitant links (links from predators to parasites of their prey). However, we clarify prior claims that parasites ‘‘dominate’’ food web links. Although parasites can be involved in a majority of links, in most cases classic predation links outnumber classic parasitism links. Regarding network structure, observed changes in degree distributions, 14 commonly studied metrics, and link probabilities are consistent with scale-dependent changes in structure associated with changes in diversity and complexity. Parasite and free-living species thus have similar effects on these aspects of structure. However, two changes point to unique roles of parasites. First, adding parasites and concomitant links strongly alters the frequency of most motifs of interactions among three taxa, reflecting parasites’ roles as resources for predators of their hosts, driven by trophic intimacy with their hosts. Second, compared to free-living consumers, many parasites’ feeding niches appear broader and less contiguous, which may reflect complex life cycles and small body sizes. This study provides new insights about generic versus unique impacts of parasites on food web structure, extends the generality of food web theory, gives a more rigorous framework for assessing the impact of any species on trophic organization, identifies limitations of current food web models, and provides direction for future structural and dynamical models.

Many donors and recipients report an improved relationship after transplantation; however, tension, neglect, guilt, and proprietorial concern over the recipient can impede donor and recipient well-being and outcomes. We aimed to describe donor and recipient expectations and experiences of their relationship in the context of living kidney donation. Thematic synthesis of qualitative studies. Living kidney donors and recipients. Electronic databases were searched to October 2015. Thematic synthesis. From 40 studies involving 1,440 participants (889 donors and 551 recipients) from 13 countries, we identified 6 themes. "Burden of obligation" described the recipient's perpetual sense of duty to demonstrate gratitude to the donor. "Earning acceptance" was the expectation that donation would restore relationships. "Developing a unique connection" reflected the inexplicable bond that donor-recipient dyads developed postdonation. "Desiring attention" was expressed by donors who wanted recognition for the act of donation and were envious and resentful of the attention the recipient received. "Retaining kidney ownership" reflected the donor's inclination to ensure that the recipient protected "their" kidney. "Enhancing social participation" encompassed relieving both the caregiver from the constraints of dialysis and the recipient from increased involvement and contribution in family life. Non-English articles were excluded. Living kidney donation can strengthen donor-recipient relationships but may trigger or exacerbate unresolved angst, tension, jealousy, and resentment. Facilitating access to pre- and posttransplantation psychological support that addresses potential relationship changes may help donors and recipients better adjust to changes in the relationship dynamics, which in turn may contribute to improved psychosocial and transplantation outcomes following living kidney donation.

2003-09-01

Over the past century and continuing to evolve into the twenty-first century, there have been dramatic changes in work and personal/family lives within the United States. These changes, though strongly affecting men and children, have impacted most dramatically on women's lives, particularly white, middle-class women. Psychiatrists and other mental health clinicians need to be aware of the scope and nature of these changes and to recognize that their own personal experiences and values might differ from those of women of different generations as well as different socioeconomic and cultural backgrounds.

2014-01-07

A new BODIPY-azaindole based fluorescent sensor 1 was designed and synthesized as a new colorimetric and ratiometric fluorescent chemosensor for fluoride. The binding and sensing abilities of sensor 1 towards various anions were studied by absorption, emission and (1)H NMR titration spectroscopies. The spectral responses of 1 to fluoride in acetonitrile-water were studied: an approximately 69 nm red shift in absorption and ratiometric fluorescent response was observed. The striking light yellow to deep brown color change in ambient light and green to blue emission color change are thought to be due to the deprotonation of the indole moiety of the azaindole fluorophore. From the changes in the absorption, fluorescence, and (1)H NMR titration spectra, proton-transfer mechanisms were deduced. Density function theory and time-dependent density function theory calculations were conducted to rationalize the optical response of the sensor. Results were supported by confocal fluorescence imaging and MTT assay of live cells.

Fluorescent protein-based indicators for intracellular environment conditions such as pH and ion concentrations are commonly used to study the status and dynamics of living cells. Despite being an important factor in many biological processes, the development of an indicator for the physicochemical state of water, such as pressure, viscosity and temperature, however, has been neglected. We here found a novel mutation that dramatically enhances the pressure dependency of the yellow fluorescent protein (YFP) by inserting several glycines into it. The crystal structure of the mutant showed that the tyrosine near the chromophore flipped toward the outside of the β-can structure, resulting in the entry of a few water molecules near the chromophore. In response to changes in hydrostatic pressure, a spectrum shift and an intensity change of the fluorescence were observed. By measuring the fluorescence of the YFP mutant, we succeeded in measuring the intracellular pressure change in living cell. This study shows a new strategy of design to engineer fluorescent protein indicators to sense hydrostatic pressure. PMID:24014139

To document the changes in BMI and the prevalence of overweight and obesity in young women living in poverty in a semi-urban community in Mexico. Women who had previously participated in a longitudinal research study (1997-2000) were re-assessed in 2005. Anthropometric measurements were obtained using standard procedures, and socio-demographic questionnaires were administered. Total and annual rate of change in BMI and change in the prevalence of overweight and obesity (BMI > or = 25.0 and > or =30.0) were estimated. Mean age in 2005 was 30.0 +/- 5.7 years (n = 683) and time between recruitment and follow-up was 6.4 +/- 1.0 years. Mean change in BMI was +3.6 +/- 2.7 (range -8.2 to +14.6). In 2005, 500 (73.2%) women were overweight, up from 263 (38.5%) in the original assessment. The prevalence of obesity tripled over the follow-up period (from 9.8% to 30.3%). The mean annual rate of change in BMI was +0.6 (+/-0.4). After adjustment for age and parity at baseline, an annual rate of change of BMI above the sample median (>0.5) was associated with lower levels of formal education. The annual increase in the prevalence of overweight and obesity in this sample is double that which was reported at a national level in Mexico. An understanding of the determinants of this rapid increase among the women living in poverty in Mexico is urgently needed.

Objective To analyze the effect of market-level changes in assisted living supply on nursing home utilization and resident acuity. Data Sources Primary data on the supply of assisted living over time were collected from 13 states from 1993 through 2007 and merged with nursing home-level data from the Online Survey Certification and Reporting System and market-level information from the Area Resource File. Study Design Least squares regression specification incorporating market and time-fixed effects. Principal Findings A 10 percent increase in assisted living capacity led to a 1.4 percent decline in private-pay nursing home occupancy and a 0.2–0.6 percent increase in patient acuity. Conclusions Assisted living serves as a potential substitute for nursing home care for some healthier individuals with greater financial resources, suggesting implications for policy makers, providers, and consumers.

A comprehensive dataset for the Georges Bank region is used to directly compare the distribution of the death assemblage and the living community at large spatial scales and to assess the application of the death assemblage in tracking changes in species' distributional pattern as a consequence of climate change. Focus is placed on the biomass-dominant clam species of the northwest Atlantic continental shelf: the surfclam Spisula solidissima and the ocean quahog Arctica islandica, for which extensive datasets exist on the distributions of the living population and the death assemblage. For both surfclams and ocean quahogs, the distribution of dead shells, in the main, tracked the distribution of live animals relatively closely. Thus, for both species, the presence of dead shells was a positive indicator of present, recent, or past occupation by live animals. Shell dispersion within habitat was greater for surfclams than for ocean quahogs either due to spatial time averaging, animals not living in all habitable areas all of the time, or parautochthonous redistribution of shell. The regional distribution of dead shell differed from the distribution of live animals, for both species, in a systematic way indicative of range shifts due to climate change. In each case the differential distribution was consistent with warming of the northwest Atlantic. Present-day overlap of live surfclams with live ocean quahogs was consistent with the expectation that the surfclam's range is shifting into deeper water in response to the recent warming trend. The presence of locations devoid of dead shells where live surfclams nevertheless were collected measures the recentness of this event. The presence of dead ocean quahog shells at shallower depths than live ocean quahogs offers good evidence that a range shift has occurred in the past, but prior to the initiation of routine surveys in 1980. Possibly, this range shift tracks initial colonization at the end of the Little Ice Age.

Many studies have been done on the physical and biological effects of space on the human body. The psychological effects of living in space are also being analyzed including the stressors from living in an isolated environment. But are we paying enough attention to what seems to be a positive effect on the human psyche, that is, the effect on astronauts and cosmonauts of the magnificent view of Earth from space? Does the length of time spent looking out the window affect our consciousness? Who comes back changed? And why? Such a social experiment needs more participants. Could democratic access to the view via suborbital space tourism change our Earth for the better?

Quantifying the Modern City: Emerging Technologies and Big Data for Active Living Research.

Opportunities and infrastructure for active living are an important aspect of a community's design, livability, and health. Features of the built environment influence active living and population levels of physical activity, but objective study of the built environment influence on active living behaviors is challenging. The use of emerging technologies for active living research affords new and promising means to obtain objective data on physical activity behaviors and improve the precision and accuracy of measurements. This is significant for physical activity promotion because precise measurements can enable detailed examinations of where, when, and how physical activity behaviors actually occur, thus enabling more effective targeting of particular behavior settings and environments. The aim of this focused review is to provide an overview of trends in emerging technologies that can profoundly change our ability to understand environmental determinants of active living. It discusses novel technological approaches and big data applications to measure and track human behaviors that may have broad applications across the fields of urban planning, public health, and spatial epidemiology.

Interactive effects of live coral and structural complexity on the recruitment of reef fishes

Corals reefs are subjected to multiple disturbances that modify levels of coral cover and structural complexity of the reef matrix, and in turn influence the structure of associated fish communities. With disturbances predicted to increase, insight into how changes in substrate condition will influence the recruitment of many fishes is essential for understanding the recovery of reef fish populations following biological and physical disturbances. While studies have revealed that both live coral cover and structural complexity are important for many fishes, there is a lack of understanding regarding how a combination of these changes will impact the recruitment of fishes. This study used experimentally constructed patch reefs consisting of six different habitat treatments; three levels of live coral cover (high, medium, low) crossed with two levels of structural complexity (high, low), to test the independent and combined effects of live coral cover and structural complexity on the recruitment and recovery of fish communities. The abundance and species diversity of fishes varied significantly among the six habitat treatments, but differences were not clearly associated with either coral cover or structural complexity and varied through time. More striking, however, was a significant difference in the composition of fish assemblages among treatments, due mostly to disproportionate abundance of coral-dwelling fishes on high coral cover, high complexity reefs. Overall, it appears that coral cover had a more important influence than structural complexity, at least for the contrasting levels of structural complexity achieved on experimental patch reefs. Furthermore, we found that live coral cover is important for the recruitment of some non-coral-dependent fishes. This study confirms that live coral cover is critical for the maintenance of high biodiversity on tropical coral reefs, and that sustained and ongoing declines in coral cover will adversely affect recruitment for many different species of reef fishes.

Normal rates of cognitive change in successful aging: the freedom house study.

2005-11-01

We determined the rates of cognitive change associated with twenty individual measures. Participants included 547 noninstitutionalized septuagenarians and octogenarian residents of a comprehensive care retirement community who were studied over three years. Latent growth curves (LGC) of multiple cognitive measures were compared to a LGC model of the rates of change in Activities of Daily Living (ADL) and Instrumental Activities of Daily Living (IADL). All curves were standardized relative to each variable's baseline distribution. Baseline scores were within their expected normal age-specific ranges. Most measures showed significant rates of change over time. There was also significant variability about those rates, suggesting clinical heterogeneity. Many deteriorated over time, as did ADLs and IADLs. However, performance on some measures improved, consistent with learning effects. The rates of change in two measures, the Executive Interview and the Trail Making Test, were closely related to decline in IADLs. These results suggest that age-related cognitive decline is a dynamic longitudinal process affecting multiple cognitive domains. Heterogeneity in the rates of cognitive change may reflect the summed effects of age and comorbid conditions affecting cognition. Some measures may be ill-suited for measuring age-related changes in cognition, either because they are insensitive to change, or hindered by learning effects. Nonverbal measures appear to be particularly well suited for the prediction of age-related functional decline. These observations are relevant to the definition and diagnosis of "dementing" conditions.

The study aimed to describe the quality of attachment in the sample of children living in St Petersburg (Russian Federation). Up to the present there were no studies on quality of attachment relationship among infants living in families in the Russian Federation (RF), including families living in St Petersburg. The study results have an important value for understanding of development of attachment patterns in a changing society with a previous history of being a totalitarian state. The St Petersburg sample consisted of 130 children, living in families, aged 11-16 months old (mean = 13.3 months). Children were living in largely normative low-risk families. The Strange Situation Procedure was used (Ainsworth Blehar, Waters, & Wall, 1978). The attachment categories were classified according to the criteria of the DMM model (Crittenden, 2002). Results presented show that 50% of children showed the complex strategies (pre-A3-4 compulsive caregiving and compliant, pre-C3-4 aggressive and feigned helpless, A/C). It was found that among a St Petersburg sample of families there was small number of children with secure attachment pattern and many children with complex attachment strategies.

The Uruguayan population is sensitized toward transplantation. However, it has not been studied how this awareness can change when emigrating to different countries. To analyze the attitude toward cadaveric organ donation and living organ donation between the Uruguayan population residing in Florida (United States) and the Uruguayan population residing in Spain. Adults born in Uruguay and residing in Florida and Spain were screened. The questionnaire "PCID-DTO Ríos" (donation of cadaveric organs) and "PCID-DVR Ríos" (living renal donation) were used. Subjects were randomly selected according to age and gender stratification. Support from Latin-American immigration associations in Spain and Florida was needed. The survey was anonymized and self-administered. Verbal consent was obtained to collaborate in the study. Because the emigrant population to Spain is far larger than the emigrant population to the United States, a 2:1 proportional sampling was performed (n = 132). Sixty-seven percent of residents in Spain were in favor of organ donation at the time of death compared with 50% among residents in Florida (P = .082), and 100% of residents in Spain were in favor of living renal donation compared with 50% of those living in Florida (P < .001). The attitude toward donation is more favorable among Uruguayan emigrants to Spain than emigrants to the United States, especially in related kidney donation. Copyright © 2017 Elsevier Inc.

Living with early-stage dementia: a review of qualitative studies.

2006-06-01

This paper presents a literature review whose aim was to provide better understanding of living with early-stage dementia. Even in the early stages, dementia may challenge quality of life. Research on early-stage dementia is mainly in the domain of biomedical aetiology and pathology, providing little understanding of what it means to live with dementia. Knowledge of the lived experience of having dementia is important in order to focus pro-active care towards enhancing quality of life. Qualitative research is fundamentally well suited to obtaining an insider's view of living with early-stage dementia. We performed a meta-synthesis of qualitative research findings. We searched MEDLINE, CINAHL, and PsycINFO and reviewed the papers cited in the references of pertinent articles, the references cited in a recently published book on the subjective experience of dementia, one thesis, and the journal Dementia. Thirty-three pertinent articles were identified, representing 28 separate studies and 21 different research samples. Findings were coded, grouped, compared and integrated. Living with dementia is described from the stage a person discovers the memory impairment, through the stage of being diagnosed with dementia, to that of the person's attempts to integrate the impairment into everyday life. Memory loss often threatens perceptions of security, autonomy and being a meaningful member of society. At early stages of memory loss, individuals use self-protecting and self-adjusting strategies to deal with perceived changes and threats. However, the memory impairment itself may make it difficult for an individual to deal with these changes, thereby causing frustration, uncertainty and fear. Our analysis supports the integration of proactive care into the diagnostic process, because even early-stage dementia may challenge quality of life. Moreover, this care should actively involve both the individual with dementia and their family so that both parties can adjust positively to living with dementia.

The Physics of Open Ended Evolution

NASA Astrophysics Data System (ADS)

Adams, Alyssa M.

What makes living systems different than non-living ones? Unfortunately this question is impossible to answer, at least currently. Instead, we must face computationally tangible questions based on our current understanding of physics, computation, information, and biology. Yet we have few insights into how living systems might quantifiably differ from their non-living counterparts, as in a mathematical foundation to explain away our observations of biological evolution, emergence, innovation, and organization. The development of a theory of living systems, if at all possible, demands a mathematical understanding of how data generated by complex biological systems changes over time. In addition, this theory ought to be broad enough as to not be constrained to an Earth-based biochemistry. In this dissertation, the philosophy of studying living systems from the perspective of traditional physics is first explored as a motivating discussion for subsequent research. Traditionally, we have often thought of the physical world from a bottom-up approach: things happening on a smaller scale aggregate into things happening on a larger scale. In addition, the laws of physics are generally considered static over time. Research suggests that biological evolution may follow dynamic laws that (at least in part) change as a function of the state of the system. Of the three featured research projects, cellular automata (CA) are used as a model to study certain aspects of living systems in two of them. These aspects include self-reference, open-ended evolution, local physical universality, subjectivity, and information processing. Open-ended evolution and local physical universality are attributed to the vast amount of innovation observed throughout biological evolution. Biological systems may distinguish themselves in terms of information processing and storage, not outside the theory of computation. The final research project concretely explores real-world phenomenon by means of mapping dominance hierarchies in the evolution of video game strategies. Though the main question of how life differs from non-life remains unanswered, the mechanisms behind open-ended evolution and physical universality are revealed.

America's older adult population is increasing at a dramatic rate due to better health care, technology, and improved living conditions. However, as individuals 65 years and older begin to live longer and experience multiple life changes, there is a larger incidence of social isolation leading to loneliness, depression, and a general decline in health. This mixed-method study aimed to explore whether information and communication technologies, specifically iPads, improved the lives of older adults. Our findings suggest that the use of technology increased knowledge, elicited closer family ties, and led to a greater overall connection to society. © The Author(s) 2015.

Interactions between semiconductor nanowires and living cells.

Prinz, Christelle N

2015-06-17

Semiconductor nanowires are increasingly used for biological applications and their small dimensions make them a promising tool for sensing and manipulating cells with minimal perturbation. In order to interface cells with nanowires in a controlled fashion, it is essential to understand the interactions between nanowires and living cells. The present paper reviews current progress in the understanding of these interactions, with knowledge gathered from studies where living cells were interfaced with vertical nanowire arrays. The effect of nanowires on cells is reported in terms of viability, cell-nanowire interface morphology, cell behavior, changes in gene expression as well as cellular stress markers. Unexplored issues and unanswered questions are discussed.

Correlated Light and Electron Microscopy/Electron Tomography of Mitochondria In Situ

Perkins, Guy A.; Sun, Mei G.; Frey, Terrence G.

2009-01-01

Three-dimensional light microscopy and three-dimensional electron microscopy (electron tomography) separately provide very powerful tools to study cellular structure and physiology, including the structure and physiology of mitochondria. Fluorescence microscopy allows one to study processes in live cells with specific labels and stains that follow the movement of labeled proteins and changes within cellular compartments but does not have sufficient resolution to define the ultrastructure of intracellular organelles such as mitochondria. Electron microscopy and electron tomography provide the highest resolution currently available to study mitochondrial ultrastructure but cannot follow processes in living cells. We describe the combination of these two techniques in which fluorescence confocal microscopy is used to study structural and physiologic changes in mitochondria within apoptotic HeLa cells to define the apoptotic timeframe. Cells can then be selected at various stages of the apoptotic timeframe for examination at higher resolution by electron microscopy and electron tomography. This is a form of “virtual” 4-dimensional electron microscopy that has revealed interesting structural changes in the mitochondria of HeLa cells during apoptosis. The same techniques can be applied, with modification, to study other dynamic processes within cells in other experimental contexts. PMID:19348881

Women's education level, maternal health facilities, abortion legislation and maternal deaths: a natural experiment in Chile from 1957 to 2007.

The aim of this study was to assess the main factors related to maternal mortality reduction in large time series available in Chile in context of the United Nations' Millennium Development Goals (MDGs). Time series of maternal mortality ratio (MMR) from official data (National Institute of Statistics, 1957-2007) along with parallel time series of education years, income per capita, fertility rate (TFR), birth order, clean water, sanitary sewer, and delivery by skilled attendants were analysed using autoregressive models (ARIMA). Historical changes on the mortality trend including the effect of different educational and maternal health policies implemented in 1965, and legislation that prohibited abortion in 1989 were assessed utilizing segmented regression techniques. During the 50-year study period, the MMR decreased from 293.7 to 18.2/100,000 live births, a decrease of 93.8%. Women's education level modulated the effects of TFR, birth order, delivery by skilled attendants, clean water, and sanitary sewer access. In the fully adjusted model, for every additional year of maternal education there was a corresponding decrease in the MMR of 29.3/100,000 live births. A rapid phase of decline between 1965 and 1981 (-13.29/100,000 live births each year) and a slow phase between 1981 and 2007 (-1.59/100,000 live births each year) were identified. After abortion was prohibited, the MMR decreased from 41.3 to 12.7 per 100,000 live births (-69.2%). The slope of the MMR did not appear to be altered by the change in abortion law. Increasing education level appears to favourably impact the downward trend in the MMR, modulating other key factors such as access and utilization of maternal health facilities, changes in women's reproductive behaviour and improvements of the sanitary system. Consequently, different MDGs can act synergistically to improve maternal health. The reduction in the MMR is not related to the legal status of abortion.

Outcome related to impact on daily living: preliminary validation of the ORIDL instrument.

2007-09-02

The challenge of finding practical, patient-rated outcome measures is a key issue in the evaluation of health care systems and interventions. The ORIDL (Outcome in Relation to Impact on Daily Living) instrument (formerly referred to as the Glasgow Homoeopathic Hospital Outcomes Scale or GHHOS) has been developed to measure patient's views of the outcome of their care by asking about change, and relating this to impact on daily life. The aim of the present paper is to describe the background and potential uses of the ORIDL, and to report on its preliminary validation in a series of three studies in secondary and primary care. In the first study, 105 patients attending the Glasgow Homoeopathic Hospital (GHH) were followed-up at 12 months and changes in health status were measured by the EuroQol (EQOL) and the ORIDL. In the second study, 187 new patients at the GHH were followed-up at 3, 12, and 33 months, using the ORIDL, the Short Form 12 (SF-12), and the Measure Yourself Medical Outcome Profile (MYMOP). In study three, 323 patients in primary care were followed for 1 month post-consultation using the ORIDL and MYMOP. In all 3 studies the Patient Enablement Instrument (PEI) was also used as an outcome measure. Study 1 showed substantial improvements in main complaint and well-being over 12 months using the ORIDL, with two-thirds of patients reporting improvements in daily living. These improvements were not significantly correlated with changes in serial measures of the EQOL between baseline and 12 months, but were correlated with the EQOL transitions measure. Study 2 showed step-wise improvements in ORIDL scores between 3 and 33 months, which were only weakly associated with similar changes in SF-12 scores. However, MYMOP change scores correlated well with ORIDL scores at all time points. Study 3 showed similar high correlations between ORIDL scores and MYMOP scores. In all 3 studies, ORIDL scores were also significantly correlated with PEI-outcome scores. There is significant agreement between patient outcomes assessed by the ORIDL and the EQOL transition scale, the MYMOP, and the PEI-outcome instrument, suggesting that the ORIDL may be a valid and sensitive tool for measuring change in relation to impact on life.

A longitudinal qualitative study examining the factors impacting on the ability of persons with T1DM to assimilate the Dose Adjustment for Normal Eating (DAFNE) principles into daily living and how these factors change over time

PubMed Central

2011-01-01

Background The literature reveals that structured education programmes, such as DAFNE, result in many positive outcomes for people with Type 1 diabetes including a decrease in HbA1c levels and reductions in hypoglycaemia. While there is evidence that some of these outcomes are maintained we do not know at present what factors are most important over time. The study aim was to identify the key factors impacting on persons with Type 1 diabetes ability to assimilate the Dose Adjustment For Normal Eating (DAFNE) DAFNE principles into their daily lives and how these factors change over time. Methods This is a longitudinal descriptive qualitative study. Interviews were undertaken with 40 participants who had attended DAFNE in one of 5 study sites across the Island of Ireland, at 6 weeks, 6 and 12 months after completion of the programme. The interviews lasted from 30 to 60 minutes and were transcribed verbatim. Data were analysed in three ways, a within time analysis, a cross sectional analysis for each participant and a thematic analysis which focused on examining changes over time Results Four themes that influenced participants' ability to assimilate DAFNE into their daily lives over time were identified. These were: embedded knowledge, continued responsive support, enduring motivation and being empowered. Support at the 6 month period was found to be crucial to continued motivation. Conclusions Understanding the factors that influence people's ability to assimilate DAFNE principles over time into their daily lives can help health professionals give focused responsive support that helps people with diabetes become more empowered. Understanding that continued support matters, particularly around 6 months, is important as health professionals can influence good management by providing appropriate support and enhancing motivation.

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

Substantial Changes in Mastery Perceptions of Dementia Caregivers With the Placement of a Care Recipient

PubMed Central

2013-01-01

Objectives. The current study examined how a key component of caregiving stress processes, global mastery perceptions, changes with placing the care recipient in a nursing home or institution. We also explored the role of primary stressors in accounting for mastery changes with placement and whether characteristics of the caregiver and care recipient moderate reactions to placement. Method. We applied multiphase growth curve models to prospective longitudinal data from 271 caregivers in the Caregiver Stress and Coping Study who experienced placement of their care recipient. Results. Using a time-to/from-placement metric, we found that caregivers typically experienced declines in mastery preceding placement, followed by a significant increase within 1 year after placement and further increases thereafter. Corresponding changes in primary stressors (role overload) mediated the placement-related increase in mastery. Caregivers who reported more depressive symptoms and activities of daily living/instrumental activities of daily living dependencies of the care recipient were more likely to experience larger placement-related increases in mastery perceptions. Discussion. Our findings suggest that placement alters psychological resources of caregivers and this effect is driven by corresponding changes in primary stressors. Findings also underscore the importance of examining change processes across salient life events and transitions. PMID:22956053

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

Longitudinal changes in maternal and neonatal anthropometrics: a case study of the Helsinki Birth Cohort, 1934-1944.

PubMed

Moltchanova, E; Eriksson, J G

2015-08-01

Changes in anthropometrics often reflect changes in living conditions, and one's characteristics at birth may be associated with future health. The aim of this study was to investigate the secular trends in maternal and neonatal anthropometrics in the Helsinki Birth Cohort Study. The study participants, thus, comprised all 13,345 live births recorded in Helsinki, Finland, between 1934 and 1944. Adult characteristics of the clinical subsample comprised of 2003 individuals, alive during 2003, were also analyzed. Linear Regression analysis with seasonal terms was applied to see whether clinically and statistically significant trends can be found in maternal age, height and body mass index (BMI) at pregnancy; gestational age, birth weight, ponderal index and sex ratio; and adult height, BMI and fat percentage. Statistically significant trends were found in maternal age and maternal BMI with abrupt changes between 1941 and 1944. Gestational age increased by an average of 0.11% per year (P<0.0001), and the proportion of premature births dropped from 7.9% in 1934 to 4.5% in 1944 (P<0.0001). In the clinical sample, a statistically significant, although small, average annual increase of 0.1% in adult heights was detected (P=0.0012 for men and P=0.0035 for women). In conclusion, although no significant changes were found in either neonatal or adult anthropometrics of babies born in Helsinki between 1934 and 1944, there were abrupt changes in the characteristics of their mothers.

2015-02-01

This study sought to understand the perceptions of Ghanaian immigrants of the health status and health trajectory of their community. We conducted focus groups and interviews with 63 primarily Ghanaian immigrants living in New York City. Nearly all participants observed that Ghanaians are generally healthy when they arrive in the US, but that their health declines over time. Participants identified four causes of this perceived deterioration: changes in health behaviors, increased stress, environmental exposures, and barriers to health care. Participants see themselves as being at risk for many health problems resulting from changes in lifestyle that follow immigration. Although some vulnerabilities are unique to their experience as immigrants, many of the risk factors they described are the same as those that affect other residents in the communities in which they live.

Single-parent households and children's educational achievement: A state-level analysis.

Amato, Paul R; Patterson, Sarah; Beattie, Brett

2015-09-01

Although many studies have examined associations between family structure and children's educational achievement at the individual level, few studies have considered how the increase in single-parent households may have affected children's educational achievement at the population level. We examined changes in the percentage of children living with single parents between 1990 and 2011 and state mathematics and reading scores on the National Assessment of Educational Progress. Regression models with state and year fixed effects revealed that changes in the percentage of children living with single parents were not associated with test scores. Increases in maternal education, however, were associated with improvements in children's test scores during this period. These results do not support the notion that increases in single parenthood have had serious consequences for U.S. children's school achievement. Copyright © 2015 Elsevier Inc. All rights reserved.

Academically at-risk students' perceptions of a constructivist high school biology pedagogy

NASA Astrophysics Data System (ADS)

Sweeney, Heidi

Successful completion of the Living Environment, one state's high school biology course, is a state graduation requirement. The academically at-risk students enrolled in one suburban public high school had been disproportionately unsuccessful at achieving a passing grade in this course. In response, a constructivist biology curriculum was created to address the needs of at-risk students in a heterogeneous ability classroom. There is a gap in current research on students' perceptions of their learning experiences; consequently, the purpose of this phenomenological study was to obtain at-risk students' perceptions of a constructivist-based curriculum and to clarify what aspects of the Living Environment course assisted in their success. Eight academically at-risk students who successfully passed the Living Environment course were surveyed to seek their perceptions of the curricular and pedagogical change. These data were analyzed using the typological method with the inclusion of both inductive and predetermined categories. The students stated a preference for group work and active engagement. They also found that the binder system introduced in the course kept them better organized and helped them increase academic performance. Students perceived that effort was required but was rewarding. Findings derived from this study may contribute to social change by assisting teachers in tailoring curriculum and pedagogical decisions. This study provided a voice for the academically at-risk student and, in doing so, may contribute to social change by providing insight to teachers and administrators that can help students succeed academically, increase graduation rates, and enhance employment opportunities.

Risk communication: climate change as a human-health threat, a survey of public perceptions in Malta.

DeBono, Roberto; Vincenti, Karen; Calleja, Neville

2012-02-01

Scientific evidence shows that climate change is very likely the product of human behaviour and lifestyle. The effects of climate change on human health are diverse in nature and range from direct effects due to extreme weather events such as heat waves, floods and storms, to indirect effects such as those caused by water and food shortages. A telephone survey was conducted between January and February 2009, on a stratified representative random sample of the Maltese population over the age of 18 years (N = 310,819). Five hundred and forty-three individuals successfully participated in the survey giving a response rate of 92.7%. The respondent sample was very similar to the target population by gender (P = 0.977), age (P = 0.767) and district (P = 0.812). The results of the study demonstrate a very strong relationship between the perception of climate change as a threat to health and well-being, support for climate change mitigation policy and a willingness to implement measures to address climate change. The findings of this study show that the perception that climate change may claim lives, cause disease, reduce the standard of living and worsen water shortages, may be the strongest driver behind support for climate change mitigation policy and a willingness to act. It is recommended that, in order to gain more public support, climate change campaigns and risk communication strategies should frame climate change as a threat to human health and general well-being.

Changes in living arrangements (from living with, or not living with family) may affect the health-related quality of life (HRQoL). This study aimed to investigate the impact of living arrangement on HRQoL among adolescents migrating from rural to urban schools, and whether social support, in addition to living with a family, had an impact. A cross-sectional survey of 459 school adolescents was carried out in two public schools in Guyuan County, Ningxia Hui Autonomous Region, China in 2015. The survey contained the following questionnaires: a self-designed questionnaire, the 12-item Short Form Health Survey (SF-12), and the Social Support Rating Scale (SSRS). Of the 459 adolescents sampled (aged 15.41 ± 1.07 years with range of 13 to 18), 61.7% were living with family, and 38.3% were not living with family. Those students not living with families had lower Mental Component Scale (MCS) scores as well as less social support overall. Those students, who were not living with families, also reported more chronic health problems and more alcohol consumption compared to those students living with families. Social support was a statistically significant mediating factor on the effect of living arrangements on MCS. Our findings demonstrated that those students, who were not living with families, tended to have more health-related quality of life issues, but social support partially mediated the relationship between living arrangements and health.

Evaluating technology options to mitigate the climate impacts of road transportation can be challenging, particularly when they involve a tradeoff between long-lived emissions (e.g., carbon dioxide) and short-lived emissions (e.g., methane or black carbon). Here we present trends in short- and long-lived emissions for light- and heavy-duty transport globally and in the U.S., EU, and China over the period 2000-2030, and we discuss past and future changes to vehicle technologies to reduce these emissions. We model the tradeoffs between short- and long-lived emission reductions across a range of technology options, life cycle emission intensities, and equivalency metrics. While short-lived vehicle emissions have decreased globally over the past two decades, significant reductions in CO 2 will be required by mid-century to meet climate change mitigation targets. This is true regardless of the time horizon used to compare long- and short-lived emissions. The short-lived emission intensities of some low-CO 2 technologies are higher than others, and thus their suitability for meeting climate targets depends sensitively on the evaluation time horizon. Other technologies offer low intensities of both short-lived emissions and CO 2 .

2017-09-01

This study sought to explore, describe and determine whether an HIV stigma-reduction community "hub" intervention would change the HIV stigma experiences of people living with HIV (PLWH) and the stigmatisation by the community in an urban area in South Africa. A convergent parallel mixed-method design with a single case pre-test post-test design and an interpretive description approach was utilised. The sample for this study included 62 PLWH recruited through accessibility sampling and 570 community members recruited through random voluntary sampling. A sub-sample of both groups, selected using purposive voluntary sampling, was utilised for the in-depth interviews about stigma experiences of PLWH, and for perceptions and attitudes of the community toward PLWH. Both quantitative and qualitative data showed that stigma is present. Although no statistically significant changes were found, small practically significant changes were demonstrated in the experiences of PLWH and in the perceptions and attitudes of the community. The extent of changes was much more obvious in the responses of the PLWH and the community during their post-intervention qualitative interviews than the changes found with the quantitative measures. This study thus concludes that the HIV stigma-reduction community hub intervention was successful in initiating the onset of changes in a community through the PLWH and people living close to PLWH (PLC) as community mobilisers active in the community hub to mobilise their own communities towards HIV stigma reduction through social change.

Few nursing studies in the past two decades have focused on siblings of children with cancer. Taking care of a hospitalized child with cancer, parents might neglect other children at home. Nursing providers need more information related to siblings and their psychosocial adaptation when one of their children is diagnosed with cancer and undergoing a variety of treatment protocols. The purpose of this study was to explore the changes in the experiences of preschool and school age siblings of children with cancer. A phenomenological study was conducted at a teaching hospital in southern Taiwan. Three children aged between five and nine years old who were siblings of a hospitalized cancer patient were approached in 2003-2004. Their families were also interviewed. Data included in-depth, formal and informal interviews, process recordings, drawings by the children, and a diary of reflections kept by the first author. Interviews lasted between 30 and 90 minutes. The qualitative data analysis method devised by Miles and Huberman (1994) was used. The findings indicated that there were three different changes in experience: Changes in psychological status, i.e., increase in worry about life, anxiety about the disease, and negative self-concepts; Changes in family interaction, i.e., relationship with mother, relationship with father, relationship with other siblings; Changes in social relationship, i.e., hunger for companions, changing recreation. Siblings do experience changes in their lives and may experience mal-adaptation. Nursing providers need to be aware of these changes and identify the health needs among caregivers and siblings of children with cancer. The findings of this study may be helpful to clinical nurses seeking to understand the needs of siblings of children with cancer.

To investigate the pharmacokinetics of lidocaine hydrochloride metabolized by cytochrome P450 3A4 (CYP3A4) in Chinese Han volunteers living at low altitude (LA) and in native Han and Tibetan Chinese volunteers living at high altitude, lidocaine hydrochloride 10 mg was given by intramuscular injection to 3 groups: Han volunteers living at LA, and native Han and Tibetan volunteers living at a high altitude. Blood samples were collected before the (baseline) study drug was given and at 0.25, 0.5, 1.0, 1.5, 2.0, 3.0, 4.0, 6.0, 8.0 h after study drug administration. Lidocaine hydrochloride in plasma was determined by RP-HPLC. Pharmacokinetics parameters of lidocaine hydrochloride showed that there were no significant difference between the native Han and Tibetan volunteers, but the t(1/2) was 29.8 and 29.8% higher in 2 groups, respectively, than in the LA group. To study related mechanism, the effects of exposure to chronic high-altitude hypoxia (CHH) on the activity and expression of CYP3A1 were examined in rats. Rats were divided into LA, chronic moderate altitude hypoxia, and CHH groups. CHH caused significant decreases in the activity and protein and mRNA expression of rat CYP3A1 in vivo. This study found significant changes in the disposition of lidocaine hydrochloride in native healthy Tibetan and Han Chinese subjects living at a high altitude in comparison to healthy Han Chinese subjects living at LA, it might be due to significant decreases in the activity and protein and mRNA expression of CYP3A4 under CHH condition. © 2016 S.

Dynamic detection of transient redox changes in living cells and animals has broad implications for human health and disease diagnosis, because intracellular redox homeostasis regulated by reactive oxygen species (ROS) plays important role in cell functions, normal physiological functions and some serious human diseases (e.g., cancer, Alzheimer's disease, diabetes, etc.) usually have close relationship with the intracellular redox status. Small-molecule ROS-responsive fluorescent probes can act as powerful tools for dynamic detection of ROS and redox changes in living cells and animals through fluorescence imaging techniques; and great advances have been achieved recently in the design and synthesis of small-molecule ROS-responsive fluorescent probes. This article highlights up-to-date achievements in designing and using the reaction-based small-molecule fluorescent probes (with high sensitivity and selectivity to ROS and redox cycles) in the dynamic detection of ROS and transient redox changes in living cells and animals through fluorescence imaging.

The purpose of this research was to compare individual hemoglobin mass (Hb mass ) changes following a live high-train low (LHTL) altitude training camp under either normobaric hypoxia (NH) or hypobaric hypoxia (HH) conditions in endurance athletes. In a crossover design with a one-year washout, 15 male triathletes randomly performed two 18-day LHTL training camps in either HH or NH. All athletes slept at 2,250 meters and trained at altitudes <1,200 meters. Hb mass was measured in duplicate with the optimized carbon monoxide rebreathing method before (pre) and immediately after (post) each 18-day training camp. Hb mass increased similarly in HH (916-957 g, 4.5 ± 2.2%, P < 0.001) and in NH (918-953 g, 3.8 ± 2.6%, P < 0.001). Hb mass changes did not differ between HH and NH ( P = 0.42). There was substantial interindividual variability among subjects to both interventions (i.e., individual responsiveness or the individual variation in the response to an intervention free of technical noise): 0.9% in HH and 1.7% in NH. However, a correlation between intraindividual ΔHb mass changes (%) in HH and in NH ( r = 0.52, P = 0.048) was observed. HH and NH evoked similar mean Hb mass increases following LHTL. Among the mean Hb mass changes, there was a notable variation in individual Hb mass response that tended to be reproducible. NEW & NOTEWORTHY This is the first study to compare individual hemoglobin mass (Hb mass ) response to normobaric and hypobaric live high-train low using a same-subject crossover design. The main findings indicate that hypobaric and normobaric hypoxia evoked a similar mean increase in Hb mass following 18 days of live high-train low. Notable variability and reproducibility in individual Hb mass responses between athletes was observed, indicating the importance of evaluating individual Hb mass response to altitude training.

Few long-term longitudinal studies have examined how dimensions of personality are related to work lives, especially in women. We propose a life-course framework for studying work over time, from preparatory activities (in the 20s) to descending work involvement (after age 60), using 50 years of life data from the women in the Mills Longitudinal Study. We hypothesized differential work effects for Extraversion (work as pursuit of rewards), Openness (work as self-actualization), and Conscientiousness (work as duty) and measured these 3 traits as predictor variables when the women were still in college. In a prospective longitudinal design, we then studied how these traits predicted the women's subsequent work lives from young adulthood to age 70 and how these effects depended on the changing sociocultural context. Specifically, the young adulthood of the Mills women in the mid-1960s was rigidly gender typed and family oriented; neither work nor education variables at that time were predicted from earlier personality traits. However, as women's roles changed, later work variables became related to all 3 traits, as expected from current Big Five theory and research. For example, early personality traits predicted the timing of involvement in work, the kinds of jobs chosen, and the status and satisfaction achieved, as well as continued work participation and financial security in late adulthood. Early traits were also linked to specific cultural influences, such as the traditional feminine role, the women's movement, and graduate education for careers. 2011 APA, all rights reserved

This study aimed to analyse how immigrant workers in Spain experienced changes in their working and employment conditions brought about Spain's economic recession and the impact of these changes on their living conditions and health status. We conducted a grounded theory study. Data were obtained through six focus group discussions with immigrant workers (n = 44) from Colombia, Ecuador and Morocco, and two individual interviews with key informants from Romania living in Spain, selected by theoretical sample. Three categories related to the crisis emerged--previous labour experiences, employment consequences and individual consequences--that show how immigrant workers in Spain (i) understand the change in employment and working conditions conditioned by their experiences in the period prior to the crisis, and (ii) experienced the deterioration in their quality of life and health as consequences of the worsening of employment and working conditions during times of economic recession. The negative impact of the financial crisis on immigrant workers may increase their social vulnerability, potentially leading to the failure of their migratory project and a return to their home countries. Policy makers should take measures to minimize the negative impact of economic crisis on the occupational health of migrant workers in order to strengthen social protection and promote health and well-being. © 2015 John Wiley & Sons Ltd.

Purpose We examined whether living in neighborhoods supportive of healthier diets and more active lifestyles may buffer immigrants against the unhealthy weight gain that is purported to occur with longer length of US residence. Methods Neighborhood data referring to a 1-mile buffer around participants’ baseline home addresses were linked to longitudinal data from 877 Hispanic and 684 Chinese immigrants aged 45-84 years in the Multi-Ethnic Study of Atherosclerosis. We used ethnicity-stratified linear mixed models to examine whether food and activity-based neighborhood measures (healthy food stores, walkability, and recreational facilities) were associated with change in waist circumference (WC) over a 9-year follow-up. Results Among Hispanics, living in neighborhoods with more resources for healthy food and recreational activity was related to lower baseline WC. However, there was no association with change in WC over time. Among Chinese, living in more walkable neighborhoods was associated with lower baseline WC and with slower increases in WC over time, especially among the most recent immigrant arrivals. Conclusions Where immigrants reside may have implications for health patterns that emerge with longer time in the US. PMID:26296266

For a long time, nomads living in the Arctic Circle around Siberia have been making a living by hunting reindeer traditionally. Wild reindeer have a recurrent migration every year, however, the travel-route of reindeer has been changing recently, so the nomads cannot expect the route in their traditional experience. To support them, one of authors (Tatsuzawa) investigated the route by installing GPS transmitter to some reindeer. The reason of the changing route, however, remain unclear. Previous works indicated that the reason of changing the route must be a global warming, forest fires, thunders, and floods, but they only discuss only on the basis of measurements in specific area. The purpose of this study is to research why the arctic reindeer alter the travel route annually through 1) the annual change of vegetation (NDVI: normalized difference vegetation index) in reindeer ground, and through 2) the annual change of soil water content (mNDWI: modified normalized difference water index) which can be reflected precipitation near Lena river. First, we analyzed NDVI using MODIS images that can be observed over a wide area, filmed in July and August; the reindeer started to travel. We have compared the seasonal changes of the NDVI images with the trace obtained by GPS data from 2010 to 2012. Although NDVI images in July showed similar numerical values in every year, the satellite images taken at August 29 is annually different; NDVI values become lower (0.5 or less) when the reindeer travel to the north area in winter. This suggests that reindeer move to secure enough food in the end of summer. In contrast, mNDWI becomes high when the reindeer travel to the north area. The annual changes of the route may be related to the amount of rainfall.

Social and economic measures in early childhood or adolescence appear to be associated with drinking behavior in young adulthood. Yet, there has been little investigation to what extent drinking behavior of young adults changes within young adulthood when they experience changes in social and economic measures in this significant period of their life. The impact of changes in living arrangement, education/employment, income, and deprivation on changes in average weekly alcohol units of consumption and frequency of hazardous drinking sessions per month in young adults was investigated. In total, 1,260 respondents of the New Zealand longitudinal Survey of Family, Income and Employment (SoFIE) aged 18-24 years at baseline were included. Young adults who moved from a family household into a single household experienced an increase of 2.32 (95% CI 1.02 to 3.63) standard drinks per week, whereas those young adults who became parents experienced a reduction in both average weekly units of alcohol (β = -3.84, 95% CI -5.44 to -2.23) and in the frequency of hazardous drinking sessions per month (β = -1.17, 95% CI -1.76 to -0.57). A one unit increase in individual deprivation in young adulthood was associated with a 0.48 (95% CI 0.10 to 0.86) unit increase in average alcohol consumption and a modest increase in the frequency of hazardous drinking sessions (β = 0.25, 95% CI 0.11 to 0.39). This analysis suggests that changes in living arrangement and individual deprivation are associated with changes in young adult's drinking behaviors. Alcohol harm-minimization interventions therefore need to take into account the social and economic context of young people's lives to be effective.

Marital status, health and mortality.

Marital status and living arrangements, along with changes in these in mid-life and older ages, have implications for an individual's health and mortality. Literature on health and mortality by marital status has consistently identified that unmarried individuals generally report poorer health and have a higher mortality risk than their married counterparts, with men being particularly affected in this respect. With evidence of increasing changes in partnership and living arrangements in older ages, with rising divorce amongst younger cohorts offsetting the lower risk of widowhood, it is important to consider the implications of such changes for health in later life. Within research which has examined changes in marital status and living arrangements in later life a key distinction has been between work using cross-sectional data and that which has used longitudinal data. In this context, two key debates have been the focus of research; firstly, research pointing to a possible selection of less healthy individuals into singlehood, separation or divorce, while the second debate relates to the extent to which an individual's transitions earlier in the life course in terms of marital status and living arrangements have a differential impact on their health and mortality compared with transitions over shorter time periods. After reviewing the relevant literature, this paper argues that in order to fully account for changes in living arrangements as a determinant of health and mortality transitions, future research will increasingly need to consider a longer perspective and take into account transitions in living arrangements throughout an individual's life course rather than simply focussing at one stage of the life course.

Do Transnational Child-Raising Arrangements Affect Job Outcomes of Migrant Parents? Comparing Angolan Parents in Transnational and NonTransnational Families in the Netherlands

PubMed Central

Haagsman, Karlijn

2017-01-01

Transnational family literature has established that parent–child separations affect negatively on the emotional well-being of migrant parents. Less attention has been paid to other effects separation can have on these parents’ lives. Building on insights from transnational family studies and organizational psychology, this article explores the potential link between transnational family life and job outcomes. In particular, two potential negative outcomes are analyzed—job instability and job absenteeism—by comparing Angolan parents whose children live in Angola with Angolans who live with all their children in the Netherlands. Based on mechanisms identified by organizational psychology literature, mediation analysis is conducted. Results indicate that transnational family life increases the times migrant parents change jobs, which is partly mediated by low levels of happiness. Further analyses indicate that especially transnational parents who have limited contact with their children change jobs more often. No significant differences are found with regard to job absenteeism. PMID:29593369

The opportunities for service users to develop skills for more independent living and take control of their environments are limited in secure mental health units. This paper will outline a quality improvement project that changed how the catering services were delivered in a low secure unit in East London NHS Foundation Trust (ELFT). A Quality Improvement methodology was adopted incorporating the Plan, Do, Study, Act (PDSA) cycle which included the trial of service users preparing their own meals on a daily basis. The participation rates were measured and functional daily living skills were recorded. Following success of the trial, long-term implementation of self-catering was agreed, with service users being supported to prepare a shared evening meal every day on the ward with an average of 60% participation. Functional living skills indicated an improvement in the area of process skills. The project aligned with ELFT's aims of service users working in collaboration with staff to implement changes in service delivery. PMID:28090324

Living donor kidney transplantation: "beauty and the beast"!

PubMed

Danovitch, Gabriel M

2013-01-01

The report by Terasaki and colleagues in 1995 that the outcomes of spousal and biologically unrelated transplants were essentially the same as for 1-haplotype matched living related transplants changed the course of clinical transplantation. This article, entitled metaphorically "Beauty and the Beast", describes the dramatic change in the practice of living donor transplantation that followed. In the ensuing two decades, biologically unrelated living donor transplantation became commonplace in the developed world and reached its apotheosis in cross-country living donor paired exchange programs that have made transplantation accessible to many whose donors were deemed "incompatible". Such exchanges can indeed be thought of as a "thing of beauty". Sadly, the same observation was abused to exploit vulnerable donors, and the "beast" in the form of transplant tourism became a feature of transplantation in the developing world. The responsibility of the transplant community to protect the welfare of living donors and their recipients and the key role of trust in the evaluation of living donors is discussed.

Can value for money be improved by changing the sequence of our donor work-up in the living kidney donor programme?

The aim of the study was to identify procedures of maximum importance for acceptance or rejection of kidney donation from a living donor as well as making the process more cost-effective. We identified all potential living related donors who were examined during the period between January 2002 and December 2006 at our department. The cost in euro (euro) for the programme was estimated using the Danish diagnosis-related group-system (DRG). The donor work-up programme was described. One hundred and thirty-three potential donors were identified; 66 male- and 67 female subjects, median age of 52 years (range 22-69). Sixty-four participants were rejected as donors. Abdominal CT-scan with angiography and urography ruled out 22 of the above 64 potential organ donors; thus, 48% of the volunteers for living kidney donation were unsuited for donation. Abdominal CT-scan with angiography and urography was the procedure identifying most subjects who were unsuited for kidney donation. A rearrangement of the present donor work-up programme could potentially reduce the costs from euro6911 to euro5292 per donor--saving 23% of the costs. By changing the sequence of examinations, it might be possible to cut down on time spent and number of tests needed for approving or rejecting subjects for living kidney donation.

Educating Prospective Kidney Transplant Recipients and Living Donors about Living Donation: Practical and Theoretical Recommendations for Increasing Living Donation Rates

Waterman, Amy D.; Robbins, Mark L.; Peipert, John D.

2016-01-01

A promising strategy for increasing living donor kidney transplant (LDKT) rates is improving education about living donation for both prospective kidney transplant recipients and living donors to help overcome the proven knowledge, psychological, and socioeconomic barriers to LDKT. A recent Consensus Conference on Best Practices in Live Kidney Donation recommended that comprehensive LDKT education be made available to patients at all stages of chronic kidney disease (CKD). However, in considering how to implement this recommendation across different healthcare learning environments, the current lack of available guidance regarding how to design, deliver, and measure the efficacy of LDKT education programs is notable. In the current article, we provide an overview of how one behavior change theory, the Transtheoretical Model of Behavior Change, can guide the delivery of LDKT education for patients at various stages of CKD and readiness for LDKT. We also discuss the importance of creating educational programs for both potential kidney transplant recipients and living donors, and identify key priorities for educational research to reduce racial disparities in LDKT and increase LDKT rates.

2012-01-01

The purpose of this qualitative phenomenological research study was to obtain vivid descriptions of the lived experience of nurses who participated in a student nursing association (SNA) as students. Nursing graduates from five nursing programs in Long Island, New York were identified using a purposive sampling strategy. During individual interviews, the themes of the lived experiences of the participants emerged: (1) leadership: communication, collaboration and resolving conflict, (2) mentoring and mutual support, (3) empowerment and ability to change practice, (4) professionalism, (5) sense of teamwork, and (6) accountability and responsibility. Recommendations from the study included an orientation and mentoring of new students to the SNA by senior students and faculty. Additionally, nursing faculty could integrate SNA activities within the classroom and clinical settings to increase the awareness of the benefits of participation in a student nursing organization. Recommendations for future research include a different sample and use of different research designs.

Protogyny in a tropical damselfish: females queue for future benefit.

PubMed

McCormick, Mark I

2016-01-01

Membership of the group is a balance between the benefits associated with group living and the cost of socially constrained growth and breeding opportunities, but the costs and benefits are seldom examined. The goal of the present study was to explore the trade-offs associated with group living for a sex-changing, potentially protogynous coral reef fish, the Ambon damselfish, Pomacentrus amboinensis. Extensive sampling showed that the species exhibits resource defence polygyny, where dominant males guard a nest site that is visited by females. P. amboinensis have a longevity of about 6.5 years on the northern Great Barrier Reef. While the species can change sex consistent with being a protogynous hermaphrodite, it is unclear the extent to which the species uses this capability. Social groups are comprised of one reproductive male, 1-7 females and a number of juveniles. Females live in a linear dominance hierarchy, with the male being more aggressive to the beta-female than the alpha-female, who exhibits lower levels of ovarian cortisol. Surveys and a tagging study indicated that groups were stable for at least three months. A passive integrated transponder tag study showed that males spawn with females from their own group, but also females from neighbouring groups. In situ behavioural observations found that alpha-females have priority of access to the nest site that the male guarded, and access to higher quality foraging areas. Male removal studies suggest that the alpha-females can change sex to take over from the male when the position becomes available. Examination of otolith microstructure showed that those individuals which change sex to males have different embryonic characteristics at hatching, suggesting that success may involve a component that is parentally endowed. The relative importance of parental effects and social organisation in affecting the importance of female queuing is yet to be studied, but will likely depend on the strength of social control by the dominant members of the group.

Rates of speciation and morphological evolution are correlated across the largest vertebrate radiation.

Rabosky, Daniel L; Santini, Francesco; Eastman, Jonathan; Smith, Stephen A; Sidlauskas, Brian; Chang, Jonathan; Alfaro, Michael E

2013-01-01

Several evolutionary theories predict that rates of morphological change should be positively associated with the rate at which new species arise. For example, the theory of punctuated equilibrium proposes that phenotypic change typically occurs in rapid bursts associated with speciation events. However, recent phylogenetic studies have found little evidence linking these processes in nature. Here we demonstrate that rates of species diversification are highly correlated with the rate of body size evolution across the 30,000+ living species of ray-finned fishes that comprise the majority of vertebrate biological diversity. This coupling is a general feature of fish evolution and transcends vast differences in ecology and body-plan organization. Our results may reflect a widespread speciational mode of character change in living fishes. Alternatively, these findings are consistent with the hypothesis that phenotypic 'evolvability'-the capacity of organisms to evolve-shapes the dynamics of speciation through time at the largest phylogenetic scales.

Leprosy is a contagious disease of a great disabling potential and the teenagers, living a changing phase of their lives, can be negatively influenced by the disease sequelae. This study aims to characterize the teenagers with leprosy disease according to social-demographic aspects, to proceed epidemic-operational analysis of leprosy disease; check teenagers' knowledge about leprosy disease and the way they reacted after they found out they had the disease; identify the changes occurred in the teenager's life and the difficulties after they had the disease. It is an explorative and descriptive research which involved 31 teenagers who are carriers of the leprosy disease and are assisted by the Family Health Strategy, in Sobral munipality-Ceará. The results point out the need of an integral and continuous attendance to the teenager with leprosy disease, avoiding that this disease brings significant changes to his/her life that can difficult to the construction of his/her new identity.

Living the lesson: can the Lifestyle Project be used to achieve deep learning in environmental earth science?

Students in a large, second-year environmental earth science class made significant changes to their daily lives over a three-week period to learn how small-scale actions interact with global-scaled issues such as water and energy supplies, waste management and agriculture. The Lifestyle Project (Kirk and Thomas, 2003) was slightly adapted to fit a large-class setting (350 students). Students made changes to their lifestyle in self-selected categories (water, home heating, transportation, waste, food) and created journals over a three-week period as the changes increased in difficulty. The goal of this study is to gain an understanding of which aspects of the project played a pivotal role in impacting long-term learning. Content analysis of the journal entries and follow-up interviews are used to investigate if the Lifestyle Project is having a lasting impact on the students 18 months after the initial assignment.

Meeting the home-care needs of disabled older persons living in the community: does integrated services delivery make a difference?

PubMed Central

2011-01-01

Background The PRISMA Model is an innovative coordination-type integrated-service-delivery (ISD) network designed to manage and better match resources to the complex and evolving needs of elders. The goal of this study was to examine the impact of this ISD network on unmet needs among disabled older persons living in the community. Methods Using data from the PRISMA study, we compared unmet needs of elders living in the community in areas with or without an ISD network. Disabilities and unmet needs were assessed with the Functional Autonomy Measurement System (SMAF). We used growth-curve analysis to examine changes in unmet needs over time and the variables associated with initial status and change. Sociodemographic characteristics, level of disability, self-perceived health status, cognitive functioning, level of empowerment, and the hours of care received were investigated as covariates. Lastly, we report the prevalence of needs and unmet needs for 29 activities in both areas at the end of the study. Results On average, participants were 83 years old; 62% were women. They had a moderate level of disability and mild cognitive problems. On average, they received 2.07 hours/day (SD = 1.08) of disability-related care, mostly provided by family. The findings from growth-curve analysis suggest that elders living in the area where ISD was implemented and those with higher levels of disability experience better fulfillment of their needs over time. Besides the area, being a woman, living alone, having a higher level of disability, more cognitive impairments, and a lower level of empowerment were linked to initial unmet needs (r2 = 0.25; p < 0.001). At the end of the study, 35% (95% CI: 31% to 40%) of elders with needs living in the ISD area had at least one unmet need, compared to 67% (95% CI: 62% to 71%) in the other area. In general, unmet needs were highest for bathing, grooming, urinary incontinence, walking outside, seeing, hearing, preparing meals, and taking medications. Conclusions In spite of more than 30 years of home-care services in the province of Quebec, disabled older adults living in the community still have unmet needs. ISD networks such as the PRISMA Model, however, appear to offer an effective response to the long-term-care needs of the elderly. PMID:22029878

At the end of the study, 35% (95% CI: 31% to 40%) of elders with needs living in the ISD area had at least one unmet need, compared to 67% (95% CI: 62% to 71%) in the other area. In general, unmet needs were highest for bathing, grooming, urinary incontinence, walking outside, seeing, hearing, preparing meals, and taking medications. In spite of more than 30 years of home-care services in the province of Quebec, disabled older adults living in the community still have unmet needs. ISD networks such as the PRISMA Model, however, appear to offer an effective response to the long-term-care needs of the elderly.

Abstract Objective To explore the perspectives of patients who live with multiple chronic conditions as they relate to the challenges of self-management. Data sources On September 30, 2013, we searched MEDLINE, EMBASE, and CINAHL using relevant key words including chronic disease, comorbidity, multimorbidity, multiple chronic conditions, self-care, self-management, perspective, and perception. Study selection Three reviewers assessed and extracted the data from the included studies after study quality was rated. Qualitative thematic synthesis method was then used to identify common themes. Twenty-three articles met the inclusion criteria, with most coming from the United States. Synthesis Important themes raised by people living with multiple chronic conditions related to their ability to self-manage included living with undesirable physical and emotional symptoms, with pain and depression highlighted. Issues with conflicting knowledge, access to care, and communication with health care providers were raised. The use of cognitive strategies, including reframing, prioritizing, and changing beliefs, was reported to improve people’s ability to self-manage their multiple chronic conditions. Conclusion This study provides a unique view into patients’ perspectives of living with multiple chronic conditions, which are clearly linked to common functional challenges as opposed to specific diseases. Future policy and programming in self-management support should be better aligned with patients’ perspectives on living with multiple chronic conditions. This might be achieved by ensuring a more patient-centred approach is adopted by providers and health service organizations. PMID:25642490

2013-02-01

Society's response to every dimension of global climate change is mediated by culture. We analyse new research across the social sciences to show that climate change threatens cultural dimensions of lives and livelihoods that include the material and lived aspects of culture, identity, community cohesion and sense of place. We find, furthermore, that there are important cultural dimensions to how societies respond and adapt to climate-related risks. We demonstrate how culture mediates changes in the environment and changes in societies, and we elucidate shortcomings in contemporary adaptation policy.

Iron is an essential metal for all organisms, yet disruption of its homeostasis, particularly in labile forms that can contribute to oxidative stress, is connected to diseases ranging from infection to cancer to neurodegeneration. Iron deficiency is also among the most common nutritional deficiencies worldwide. To advance studies of iron in healthy and disease states, we now report the synthesis and characterization of iron-caged luciferin-1 (ICL-1), a bioluminescent probe that enables longitudinal monitoring of labile iron pools (LIPs) in living animals. ICL-1 utilizes a bioinspired endoperoxide trigger to release d-aminoluciferin for selective reactivity-based detection of Fe 2+ with metal and oxidation state specificity. The probe can detect physiological changes in labile Fe 2+ levels in live cells and mice experiencing iron deficiency or overload. Application of ICL-1 in a model of systemic bacterial infection reveals increased iron accumulation in infected tissues that accompany transcriptional changes consistent with elevations in both iron acquisition and retention. The ability to assess iron status in living animals provides a powerful technology for studying the contributions of iron metabolism to physiology and pathology.

2018-03-01

In this paper, the fatigue lives of a new type of assembled marine floating platform for special purposes were studied. Firstly, by using ANSYS AQWA software, the hydrodynamic model of the platform was established. Secondly, the structural stresses under alternating change loads were calculated under complex water environments, such as wind, wave, current and ice. The minimum fatigue lives were obtained under different working conditions. The analysis results showed that the fatigue life of the platform structure can meet the requirements

Home Health Care Nursing Visit Intensity and Heart Failure Patient Outcomes

Riggs, Jennifer S.; Madigan, Elizabeth A.; Fortinsky, Richard H.

2012-01-01

This study is a secondary analysis of data for 107 home health care heart failure patients. The authors investigate the impact of patient characteristics and nursing visit intensity on change in activities of daily living (ADL) status and instrumental activities of daily living (IADL) status and improvement/stabilization of dyspnea. Prior hospital stay (β = .38, p = .001) and nursing visit intensity (β = −.39, p = .001) predict improvement in ADL status. The model for change in IADL status is not significant. Patients with more than two comorbidities (OR = 6.5, p = .04) and patients who received higher nursing visit intensity (OR = 7.0, p = .04) are more likely to have improved/stabilized dyspnea at home care discharge.

Sakka, D; Dikaiou, M; Kiosseoglou, G

This article addresses changes in gender roles among returning migrant families. It focuses on Greek returnees from the Federal Republic of Germany and explores changes in task sharing behavior and gender role attitudes resulting from changes in the sociocultural environments. A group of return migrants was compared with a group of non-migrants, both living in villages in the District of Drama, Greece. Groups were interviewed to investigate the extent to which each spouse shared house tasks, as well as their attitudes towards sharing and gender role in the family. The t-test for independent samples was used to determine mean differences between the two groups. In addition to demographic variables, those concerning the "time lived abroad" and the "number of years in Greece" after return were inserted into a series of regression analyses. Findings showed that migrants' task sharing and gender role attitudes were influenced differently by the migration-repatriation experience and subsequent cultural alternation. Results also suggest that migrant couples either take on new patterns of behavior or maintain traditional ones only when these were congruent with the financial aims of the family or can be integrated into living conditions in Greece upon return. Furthermore, migrants seem to adopt a more "traditional" attitude than non-migrants toward the participation of women in family decision making. From the study, it is suggested that gender role change is an on-going process influenced by the migration-repatriation experience, as well the factors, which accompany movement between the two countries.

Targeted public awareness interventions are needed to improve earlier cancer diagnosis and reduce socioeconomic inequalities in cancer outcomes. The health check (intervention) is a touchscreen questionnaire delivered by trained lay advisors that aims to raise awareness of cancer symptoms and risk factors and encourage timely help seeking. This study aimed to apply the Behavior Change Wheel to intervention refinement by identifying barriers and facilitators to timely symptom presentation among people living in socioeconomically deprived communities. Primary data (six focus groups with health professionals, community partners and public) and secondary data (systematic review of barriers and facilitators to cancer symptom presentation) were mapped iteratively to the Behavior Change Wheel. Barriers and facilitators were identified from the systematic review and focus groups comprising 14 members of the public aged over 40, 14 community partners, and 14 healthcare professionals. Barriers included poor symptom knowledge and lack of motivation to engage in preventive or proactive behaviors. Facilitators included cues/prompts to action, general practitioner preparedness to listen, and social networks. The following behavior change techniques were selected to address identified barriers and facilitators: information about health consequences, prompts/cues, credible sources, restricting physical and social environment, social support, goal setting, and action planning. The Behavior ChangeWheel triangulated findings from primary and secondary data sources. An intervention combining education and enablement could encourage timely symptom presentation to primary care among people living in socioeconomically deprived communities. Social encouragement and support is needed to increase symptom knowledge, challenge negative cancer beliefs, and prompt decisions to engage with the healthcare system.

Blood and Hair Manganese Concentrations in Pregnant Women from the Infants’ Environmental Health Study (ISA) in Costa Rica

PubMed Central

2015-01-01

Manganese (Mn), an essential nutrient, is a neurotoxicant at high concentrations. We measured Mn concentrations in repeated blood and hair samples collected from 449 pregnant women living near banana plantations with extensive aerial spraying of Mn-containing fungicide mancozeb in Costa Rica, and examined environmental and lifestyle factors associated with these biomarkers. Mean blood Mn and geometric mean hair Mn concentrations were 24.4 μg/L (8.9–56.3) and 1.8 μg/g (0.05–53.3), respectively. Blood Mn concentrations were positively associated with gestational age at sampling (β = 0.2; 95% CI: 0.1 to 0.2), number of household members (β = 0.4; 95% CI: 0.1 to 0.6), and living in a house made of permeable and difficult-to-clean materials (β = 2.6; 95% CI: 1.3 to 4.0); and inversely related to smoking (β = −3.1; 95% CI: −5.8 to −0.3). Hair Mn concentrations were inversely associated with gestational age at sampling (% change = 0.8; 95% CI: −1.6 to 0.0); and positively associated with living within 50 m of a plantation (% change = 42.1; 95% CI: 14.2 to 76.9) and Mn concentrations in drinking water (% change = 17.5; 95% CI: 12.2 to 22.8). Our findings suggest that pregnant women living near banana plantations aerially sprayed with mancozeb may be environmentally exposed to Mn. PMID:24601641

Welfare Reform has caused a dramatic change in the lives and health of single mothers living in poverty. This qualitative study explored the health and socioeconomic lives of 22 community-dwelling women in poverty in the years after they were terminated from the current work-based welfare program intended to move women from welfare to work and independence. The instruments were a semistructured interview guide, the HANES General Well-Being Schedule, and a demographic data form. Data were analyzed using multistage narrative analysis and descriptive statistics. These primary source data showed participants had multiple barriers that precede or follow poverty. Their voices of how they survive are a rich source of data to assist providers and policy makers in devising evidence-based solutions for reducing poverty in America. © The Author(s) 2016.

Background After spinal cord injury (SCI), people are confronted with abrupt discontinuity in almost all areas of life, leading to questions on how to live a meaningful life again. Global meaning refers to basic ideas and goals that guide people in giving meaning to their lives, in specific situations. Little is known about global meaning relating to SCI and whether global meaning changes after SCI. Purpose The purpose of this study was twofold: (i) to explore the content of global meaning of people with SCI, and (ii) to explore whether or not global meaning changes after SCI. Methods In-depth semi-structured interviews were conducted with 16 people with SCI. Interviews were analyzed according to the method of grounded theory. Results (i) Five aspects of global meaning were found: core values, relationships, worldview, identity and inner posture. (ii) Overall, little change in the content of global meaning was found after SCI; specific aspects of global meaning were foregrounded after SCI. Conclusion Five aspects of global meaning were found in people with SCI. Global meaning seems hardly subject to change. PMID:25615571

Tardigrades are microscopic metazoans which are able to survive extreme physical and chemical conditions by entering a stress tolerant state called cryptobiosis. At present, the molecular mechanisms behind cryptobiosis are still poorly understood. We show that surface enhanced Raman scattering supported by plasmonic gold nanoparticles can measure molecular constituents and their local distribution in live tardigrades. Surface enhanced Raman signatures allow to differentiate between two species and indicate molecular structural differences between tardigrades in water and in a dry state. This opens new avenues for exploring cryptobiosis by studying molecular changes in live cryptobiotic organisms. Copyright © 2013 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.

2014-09-01

This study analyzes the potential uses of live fences and pastures as reservoirs of plant diversity for two regions with different management histories, Los Tuxtlas (LT) and Uxpanapa (UX), Veracruz, México. We studied two habitats, live fences and pastures, analyzed their species richness, diversity, structure and plant composition and classified species according to plant regeneration modes (light-demanding and shade tolerant), seed dispersal syndrome and their local uses. We recorded 62 species of trees at LT and 48 at UX. Live fences were more diverse than pastures in both regions. The LT site showed to analyze the relationship a higher diversity of plants in regeneration stages than the one at UX. However, UX had higher diversity of adult plants in the pastures than LT. Composition and structure of live fences were different between regions, as well as within live fences and pastures, 53 % of species were light-demanding and 40 % were shade tolerant; 70 % of the species were dispersed by birds. Differences between sites are associated with the modifications in live fences structure, which changed according to managerial practices and the use of local species; this may influence plant regeneration modes as well as the visits of avian dispersal agents. In LT, all species found in live fences were useful to humans, whereas in UX, less than half were used by the local population. Our results underline the importance of live fences and isolated trees in pasture habitats as potential sites to host native and useful species from tropical rain forests in livestock landscapes.

Live-In Versus Live-Out Home Care in Israel: Satisfaction With Services and Caregivers' Outcomes.

The present study provides a preliminary examination of the relationship between the type of home care services (live-in vs. live-out; i.e., round the clock vs. several hours per week), the caregiver's satisfaction with services, and the caregiver's burden, distress, well-being, and subjective health status within the conceptual framework of caregiving outcomes proposed by Yates and colleagues (Yates, M. E., Tennstedt, S., & Chang, B. H. [1999]. Contributors to and mediators of psychological well-being for informal caregivers. Journal of Gerontology: Psychological Sciences, 54, P12 -P22. doi:10.1093/geronb/54B.1.P12). A random stratified sample of family caregivers of older adults more than the age of 70 who receive live-in (442) or live-out (244) home care services through the financial assistance of the National Insurance institute of Israel was selected. A path analysis was conducted. Satisfaction with services was higher among caregivers under the live-in home care arrangement and positively related to well-being. Among caregivers, live-in home care was directly associated with higher levels of subjective health and indirectly associated with better well-being via satisfaction with services. The present study emphasizes the potential benefits of live-in home care services for caregivers of older adults who suffer from high levels of impairment and the importance of assessing satisfaction with services as a predictor of caregivers' outcomes. © The Author 2013.

2016-01-01

Little is known about the relationship between changes in food store environment and children's obesity risk in the United States. This study examines children's weight status associated with the changes in the quantity of food stores in their neighborhoods. A nationally representative cohort of schoolchildren in the United States was followed from fifth grade in 2004 to eighth grade in 2007 (n = 7,090). In 2004 and 2007, children's body mass index (BMI) was directly measured in schools. ZIP Code Business Patterns data from the Census Bureau in 2004 and 2007 characterized the numbers of food stores in every ZIP code area by type of store: supermarkets, limited-service restaurants, small-size grocery, and convenience stores. Baseline and change in the numbers of stores were the major exposures of interest. Girls living in neighborhoods with three or more supermarkets had a lower BMI 3 years later (by -.62 kg/m(2); 95% confidence interval = -1.05 to -.18) than did those living in neighborhoods without any supermarkets. Girls living in neighborhoods with many limited-service restaurants had a greater BMI 3 years later (by 1.02 kg/m(2); 95% confidence interval = .36-1.68) than did those living in neighborhoods with less than or equal to one limited-service restaurant. Exposure to a decreased quantity of small-size grocery stores in neighborhoods was associated with girls' lower BMI by eighth grade. The longitudinal association between neighborhood food environment and children's BMI differed by gender. For girls, supermarkets in neighborhoods seemed protective against obesity, whereas small-size grocery stores and limited-service restaurants in neighborhoods increased obesity risk. There was no significant longitudinal finding for boys. Copyright © 2016 Society for Adolescent Health and Medicine. Published by Elsevier Inc. All rights reserved.

[Evidence about the power of intention].

PubMed

Bonilla, Ernesto

2008-12-01

Intention is defined as a directed thought to perform a determined action. Thoughts targeted to an end can affect inanimate objects and practically all living things from unicelular organisms to human beings. The emission of light particles (biophotons) seems to be the mechanism through which an intention produces its effects. All living organisms emit a constant current of photons as a mean to direct instantaneous nonlocal signals from one part of the body to another and to the outside world. Biophotons are stored in the intracelular DNA. When the organism is sick changes in biophotons emissions are produced.Direct intention manifests itself as an electric and magnetic energy producing an ordered flux of photons. Our intentions seem to operate as highly coherent frequencies capable of changing the molecular structure of matter. For the intention to be effective it is necessary to choose the appropriate time. In fact, living beings are mutually synchronized and to the earth and its constant changes of magnetic energy. It has been shown that the energy of thought can also alter the environment. Hypnosis, stigmata phenomena and the placebo effect can also be considered as types of intention, as instructions to the brain during a particular state of consciousness. Cases of spontaneous cures or of remote healing of extremely ill patients represent instances of an exceedingly great intention to control diseases menacing our lives. The intention to heal as well as the beliefs of the sick person on the efficacy of the healing influences promote his healing. In conclusion, studies on thought and consciousness are emerging as fundamental aspects and not as mere epiphenomena that are rapidly leading to a profound change in the paradigms of Biology and Medicine.

Family structure and breakfast consumption of 11-15 year old boys and girls in Scotland, 1994-2010: a repeated cross-sectional study

PubMed Central

2012-01-01

Background The benefits of breakfast during childhood and adolescence have been reported previously though few studies have considered family structure inequalities in breakfast consumption. The proportion of young people living in non-traditional family types has increased in recent years, strengthening the need to describe and monitor the impact of the changing family unit on adolescent breakfast consumption. This study aimed to describe changes in daily breakfast consumption among adolescents in Scotland between 1994 and 2010, while also considering family structure inequalities, and the degree to which these have changed over time. Methods Data from the 1994, 1998, 2002, 2006 and 2010 Scottish Health Behaviour in School-aged Children (HBSC) surveys were analysed using logistic multilevel regression models for binary outcome variable daily breakfast consumption. Results Daily breakfast consumption among adolescents increased between 1994 and 2010, although there were differences by age and sex. In fact those aged over 14.5 years saw decreases in breakfast consumption, and girls saw significantly larger increases than boys. Daily breakfast consumption was more prevalent among adolescents from 'both parent' families, with lowest prevalence among those from single parent families. Trends in daily breakfast consumption between 1994 and 2010 also varied by family structure. While prevalence of daily breakfast consumption increased among those living with 'both parents', the largest proportion of the population, prevalence decreased over time among adolescents of single parent families, and particularly among those living with their father. Conclusions Family structure inequalities in daily breakfast consumption increased between 1994 and 2010, while breakfast consumption across the population as a whole increased. As the proportion of young people living in an alternative family structure continues to grow it is important to understand why these inequalities have increased and how these may be overcome. Possible reasons for family structure inequalities and their increase in recent years are discussed. PMID:22440153

Vowel normalization for accent: An investigation of perceptual plasticity in young adults

Evans, Bronwen G.; Iverson, Paul

2004-05-01

Previous work has emphasized the role of early experience in the ability to accurately perceive and produce foreign or foreign-accented speech. This study examines how listeners at a much later stage in language development-early adulthood-adapt to a non-native accent within the same language. A longitudinal study investigated whether listeners who had had no previous experience of living in multidialectal environments adapted their speech perception and production when attending university. Participants were tested before beginning university and then again 3 months later. An acoustic analysis of production was carried out and perceptual tests were used to investigate changes in word intelligibility and vowel categorization. Preliminary results suggest that listeners are able to adjust their phonetic representations and that these patterns of adjustment are linked to the changes in production that speakers typically make due to sociolinguistic factors when living in multidialectal environments.

The effects of organizational and community embeddedness on work-to-family and family-to-work conflict.

PubMed

Ng, Thomas W H; Feldman, Daniel C

2012-11-01

The present study offers competing hypotheses regarding the relationships of changes in organizational and community embeddedness with changes in work-to-family and family-to-work conflict. Data were collected from 250 U.S. and 165 Chinese managers and professionals, all of whom were married, at 3 points in time over a 10-month period. Results suggest that increases in perceptions of organizational and community embeddedness are associated with increases in work-to-family conflict and family-to-work conflict over time. Further, we found that these effects were even stronger for employees with highly individualistic values. Thus, although much of the previous research has focused on the positive effects of employee embeddedness for individuals' work lives, the present study provides some evidence of the potentially negative effects of employee embeddedness for individuals' family lives.

Electroporation of the photosynthetic membrane: structural changes in protein and lipid-protein domains.

PubMed Central

Rosemberg, Y; Rotenberg, M; Korenstein, R

1994-01-01

A biological membrane undergoes a reversible permeability increase through structural changes in the lipid domain when exposed to high external electric fields. The present study shows the occurrence of electric field-induced changes in the conductance of the proton channel of the H(+)-ATPase as well as electric field-induced structural changes in the lipid-protein domain of photosystem (PS) II in the photosynthetic membrane. The study was carried out by analyzing the electric field-stimulated delayed luminescence (EPL), which originates from charge recombination in the protein complexes of PS I and II of photosynthetic vesicles. We established that a small fraction of the total electric field-induced conductance change was abolished by N,N'-dicyclohexylcarbodiimide (DCCD), an inhibitor of the H(+)-ATPase. This reversible electric field-induced conductance change has characteristics of a small channel and possesses a lifetime < or = 1 ms. To detect electric field-induced changes in the lipid-protein domains of PS II, we examined the effects of phospholipase A2 (PLA2) on EPL. Higher values of EPL were observed from vesicles that were exposed in the presence of PLA2 to an electroporating electric field than to a nonelectroporating electric field. The effect of the electroporating field was a long-lived one, lasting for a period > or = 2 min. This effect was attributed to long-lived electric field-induced structural changes in the lipid-protein domains of PS II. PMID:7811916

Not in My Backyard: CCS Sites and Public Perception of CCS.

PubMed

Braun, Carola

2017-12-01

Carbon capture and storage (CCS) is a technology that counteracts climate change by capturing atmospheric emissions of CO 2 from human activities, storing them in geological formations underground. However, CCS also involves major risks and side effects, and faces strong public opposition. The whereabouts of 408 potential CCS sites in Germany were released in 2011. Using detailed survey data on the public perception of CCS, this study quantifies how living close to a potential storage site affects the acceptance of CCS. It also analyzes the influence of other regional characteristics on the acceptance of CCS. The study finds that respondents who live close to a potential CCS site have significantly lower acceptance rates than those who do not. Living in a coal-mining region also markedly decreases acceptance. © 2017 Society for Risk Analysis.

Heart failure (HF) patients need to follow a strict pharmacological and nonpharmacological regimen in order to counteract the burden of the disease, and informal caregivers are an important resource for HF patients in managing and coping with their disease. Few studies have examined the lived experience of these caregivers with a rigorous phenomenological approach, and none have been conducted in Italy. To describe the lived experience of the caregivers of HF patients. A hermeneutic phenomenological method was used. Caregivers were enrolled in a HF clinic in central Italy. Interviews were analysed using a phenomenological approach. Credibility, dependability, confirmability and transferability were adopted in order to strengthen trustworthiness. Thirty HF caregivers (mean age: 53 years) were enrolled. Of these, 63% of the caregivers were female and 80% were patients' spouses or children. Six themes emerged: (1) fear and worry related to the illness; (2) life changes and restrictions; (3) burden due to caregiving; (4) uncertainty about illness management; (5) helping patients to cope with the illness; and (6) love and affection towards the patient. The findings of our study may help providers to guide interventions for HF caregivers. Providers should be supportive of caregivers and provide them with education in order to reduce their fears and worries about the illness and to handle the course of HF and its symptoms. An empathetic and practical approach with caregivers that considers the patient-caregiver relationship may help caregivers to cope with the changes and restrictions that caregiving brings to their lives and to reduce their burden.

Changes in student population and increased Web-based education offerings provided the impetus to assess pedagogy, cognitive outcomes and perceptions of course quality. This study explored cognitive outcomes and students' perception of course quality related to the Seven Principles for Good Practice in Undergraduate Education between live classroom delivery, compared to a Web-based delivery of a phlebotomy program. Quasi-experimental; students self-selected to enroll in live or Web-based program. For cognitive outcomes, no significant difference was found between the groups. Student perception of course quality differed only for Principle One (student-instructor contact). Students in the live classroom rated Principle One higher for the Part I course compared to the Web-based group. For the Part II course, there was no significant difference in perception of course quality related to any of the Seven Principles. The more constructivist pedagogy in the Part II course did not improve cognitive outcomes however, it may have contributed to knowledge retention. The live group rated Principle One in the Part II course evaluation relatively the same as they did for the Part I course evaluation. However, the Web-based group rated Principle One considerable higher for the Part II course than for Part I course. Future studies with a larger sample could explore improved course quality assessment instruments.

'They don't live in my house every day': How understanding lives can aid understandings of smoking.

PubMed

Robinson, Jude; Holdsworth, Clare

2013-03-01

While the prevalence of smoking in western countries has substantially reduced following the introduction of comprehensive tobacco control programs, reduction strategies such as the introduction of smokefree legislation, media campaigns and individual and group support for people trying to quit have been less successful with people living on low income, suggesting the need for new ways to engage with people who smoke. We argue that, rather than focusing solely on researching smoking behaviors to generate new understandings of why people smoke, people working in the broad area of public health should look more widely at peoples' lives in order to understand their smoking. Using a biographical, narrative perspective as part of a wider ethnographic study of 12 families living in one community within Liverpool in 2006, we argue that understandings that position smoking purely as a harmful, deviant behavior, fail to capture the cultural complexity of the lives of smokers and the changing place and meaning of cigarettes over a person's lifetime, and may explain why smokers fail to engage with smoking cessation services and continue to smoke.

Quantifying the Modern City: Emerging Technologies and Big Data for Active Living Research

2017-01-01

Opportunities and infrastructure for active living are an important aspect of a community’s design, livability, and health. Features of the built environment influence active living and population levels of physical activity, but objective study of the built environment influence on active living behaviors is challenging. The use of emerging technologies for active living research affords new and promising means to obtain objective data on physical activity behaviors and improve the precision and accuracy of measurements. This is significant for physical activity promotion because precise measurements can enable detailed examinations of where, when, and how physical activity behaviors actually occur, thus enabling more effective targeting of particular behavior settings and environments. The aim of this focused review is to provide an overview of trends in emerging technologies that can profoundly change our ability to understand environmental determinants of active living. It discusses novel technological approaches and big data applications to measure and track human behaviors that may have broad applications across the fields of urban planning, public health, and spatial epidemiology.

The effect of physical activity on musculoskeletal health in older adults is not completely understood. The aim of this study was to determine the relationship between physical activity and 5-year changes in physical performance tests and bone mineral density (BMD) in postmenopausal women. The design was a 5-year cohort study. Subjects were 507 women (55-74 years old) living in a rural community in Japan. Physical activity assessed included housework, farm work, and moderate leisure-time physical activity within the previous week. Measurements at baseline included handgrip strength, walking time (timed "Up & Go" test) and BMD of the femoral neck and vertebrae. Five-year changes in these measures (outcome variables) were compared among groups with different levels of physical activity by analysis of covariance. Women who did not do housework performed worse in changes in handgrip strength (difference=2.22 kg, P=0.0201) and worse in changes in the walking time (difference=0.54 s, P=0.0072) than those who did housework alone. Women who spent at least 9h per week (median=24) doing farm work performed better in changes in handgrip strength (difference=0.28 kg, P=0.0334), but worse in changes in the walking time (difference=0.66 s, P<0.0001) than those who did not do farm work. However, leisure-time activity was not associated with changes in any outcome variable, and none of the physical activities predicted BMD changes. Engaging in housework and farm work are determinants of physical function in postmenopausal women, which may help them maintain independence in daily living. Copyright © 2011 Elsevier Ireland Ltd.

Climate change threats to family farmers' sense of place and mental wellbeing: A case study from the Western Australian Wheatbelt.

PubMed

Ellis, Neville R; Albrecht, Glenn A

2017-02-01

'Sense of place' has become a central concept in the analysis of the cultural, personal and mental health risks posed by a changing climate. However, such place-related understandings of mental health and wellbeing remain largely limited to Indigenous health contexts. In this article we argue the relevance of sense of place in understanding the mental health impacts of climate change on family farmers who retain close living and working relationships to the land. We conducted a community-based qualitative case study located in the Western Australian Wheatbelt - a region that has experienced some of the most significant climate change in Australia. A three-part interview series was conducted with 22 family farmers between February 2013 and April 2014, and 15 interviews with various agricultural and mental health key informants. The research findings reveal that recently observed patterns of climate change have exacerbated farmers' worries about the weather, undermined notions of self-identity, and contributed to cumulative and chronic forms of place-based distress, culminating in heightened perceived risk of depression and suicide. The research findings highlight the tightly coupled ecosystem health-human health relationships that exist for family farmers living in regions affected by climate change, as well as the significance of farmers' place-based attachments and identities for their mental health and wellbeing.

Vibrational spectroscopy, when combined with synchrotron radiation-based (SR) microscopy, is a powerful new analytical tool with high spatial resolution for detecting biochemical changes in the individual living cells. In contrast to other microscopy methods that require fixing, drying, staining or labeling, SR-FTIR microscopy probes intact living cells providing a composite view of all of the molecular response and the ability to monitor the response over time in the same cell. Observed spectral changes include all types of lesions induced in that cell as well as cellular responses to external and internal stresses. These spectral changes combined with other analytical tools may provide a fundamental understanding of the key molecular mechanisms induced in response to stresses created by low- doses of chemicals. In this study we used the high spatial - resolution SR-FTIR vibrational spectromicroscopy as a sensitive analytical tool to detect chemical- and radiation- induced changes in individual human cells. Our preliminary spectral measurements indicate that this technique is sensitive enough to detect changes in nucleic acids and proteins of cells treated with environmentally relevant concentrations of dioxin. This technique has the potential to distinguish changes from exogenous or endogenous oxidative processes. Future development of this technique will allow rapid monitoring of cellular processes such as drug metabolism, early detection of disease, bio- compatibility of implant materials, cellular repair mechanisms, self assembly of cellular apparatus, cell differentiation and fetal development.

Nature-based solutions, such as living shorelines, have the potential to restore critical ecosystems, enhance coastal sustainability, and increase resilience to natural disasters; however, their efficacy during storm events compared to traditional hardened shorelines is largely untested. This is a major impediment to their implementation and promotion to policy-makers and homeowners. To address this knowledge gap, we evaluated rock sill living shorelines as compared to natural marshes and hardened shorelines (i.e., bulkheads) in North Carolina, USA for changes in surface elevation, Spartina alterniflora stem density, and structural damage from 2015 to 2017, including before and after Hurricane Matthew (2016). Our results show that living shorelines exhibited better resistance to landward erosion during Hurricane Matthew than bulkheads and natural marshes. Additionally, living shorelines were more resilient than hardened shorelines, as they maintained landward elevation over the two-year study period without requiring any repair. Finally, rock sill living shorelines were able to enhance S. alterniflora stem densities over time when compared to natural marshes. Our results suggest that living shorelines have the potential to improve coastal resilience while supporting important coastal ecosystems. © 2018 by the Ecological Society of America.

To date, whilst there have been many published studies exploring the links between masculinity and HIV, not much work has been done to explore how an HIV-positive diagnosis impacts men's sense of masculinity and contextualizing the masculinities as fluid and changing. To explore how human immunodeficiency virus (HIV) impacts the lives of men and their constructions of masculinity through interviews with 18 men living with HIV. Qualitative study involving conveniently and purposively selected black South African adult men who lived with HIV. In-depth interviews were conducted with 18 men who resided in Johannesburg and Mthatha, South Africa. Our analysis suggests that the performance of risky masculinity may influence the acquisition of HIV. Yet, it also reveals that HIV can have a significant effect on men and their masculinities. Men's constructions of harmful notions of hegemonic masculinity pre-HIV diagnosis negatively affected their help-seeking behavior and coping and adjustment to living with HIV, post-diagnosis. The dominant discourse that men are strong and healthy visibly presented challenges for men when faced with an HIV-positive status. They interpreted HIV diagnosis as a loss, a sign of failure as a man, and evidence of an inability to retain control. Being sick undermined their ability to perform roles expected of them, and this led to feelings of powerlessness, worthlessness, and distress. Interventions with men living with HIV need to provide safe spaces for men to critically explore gender and constructions of social identities and the pressures these place on men and implications for their health. With this approach, harmful constructions of masculinities may be challenged and mitigated, and this process may render men amenable to change.

The sharp decline in the total fertility rate in Poland coincided with broader socio-economic changes, which resulted in its reduction to the lowest level observed among the countries of Central and Eastern Europe. Objective. The aim of the study was to investigate and evaluate the changing patterns of reproductive behaviour in rural and urban areas, depending on the demographic and socio-economic features in Poland. Information about live births in Poland in the years 1995-2014 were obtained from the Central Statistical Office. Registered cases of live births in rural and urban areas were analyzed considering the maternal features (age, marital status, main source of income). To evaluate the changes in fertility and comparisons between rural and urban areas, Joinpoint Regresssion was used. In 1995-2014, a shift in the age of highest fertility from 20-24 years to 25-29 years was observed. This occurred at the same time as a reduction in the fertility rate per 1,000 women aged 15-29 years, more pronounced in rural areas (95.8 to 60.0) than in urban areas (63.4 to 51.5), while in women aged 30-49 years, a faster increase in fertility was observed in urban areas (16.4 to 32.0) than in rural areas (27.5-29.2). Fertility trends between rural and urban areas differed significantly. A significant increase in live births for employed mothers was shown mainly in 2005-2009; later, the growth rate in rural areas was slower and in urban areas the growth trend stopped. The postponement of births and reduction of fertility in women aged 15-29 requires active measures aimed at creating favourable conditions for achieving economic independence for the younger generation, as well as combining work with raising children, especially in rural areas.

Progressive resistive exercise interventions for adults living with HIV/AIDS.

Due to medical advancements, many people living with HIV infection in developed countries are living longer (Palella 1998). HIV infection can now present as a chronic illness with an uncertain natural disease history. The changing course of HIV infection has lead to a potential increase in the prevalence and impact of disability in people living with HIV infection. Exercise is one key management strategy used by health care professionals to address impairments (problems with body function or structure as a significant deviation or loss such as pain or weakness), activity limitations (difficulties an individual may have in executing activities such as inability to walk) and participation restrictions (problems an individual may experience in life situations such as inability to work) in this population (World Health Organization 2001). Exercise may also be used to address unwanted changes in weight and body composition in people living with HIV infection. Aerobic exercise has been associated with improvements in strength, cardiovascular function, and psychological status in general populations (Bouchard 1993). Results of a systematic review suggested that aerobic exercise interventions appeared to be safe and may lead to improvements in cardiopulmonary fitness for adults living with HIV/AIDS (Nixon 2002). But what are the effects of progressive resistive exercise (PRE) for adults living with HIV infection?A better understanding of the effectiveness and safety of progressive resistive exercise will enable people living with HIV and their health care workers to practice effective and appropriate exercise prescription, thus contributing to improved overall outcomes for adults living with HIV infection. To examine the safety and effectiveness of progressive resistive exercise interventions on weight, body composition, strength, immunological/virological, cardiopulmonary and psychological parameters in adults living with HIV infection. To identify studies to be included in this review, we searched the following databases: MEDLINE, EMBASE, CINAHL, COCHRANE, SCIENCE CITATION INDEX, PSYCHINFO, SOCIOLOGICAL ABSTRACTS, SSCI, ERIC, DAI and HEALTHSTAR. We also reviewed both published and unpublished abstracts and proceedings from major international and national HIV/AIDS conferences such as the Interscience Conference on Antimicrobial Agents and Chemotherapy (ICAAC), the Conference on Retroviruses and Opportunistic Infections (CROI), the Infectious Diseases Society of America Conference (IDSA), and the International AIDS Conference (IAC). Reference lists from pertinent articles and books were reviewed, as well as Collaborative Review Group databases. Targeted journals were also hand searched for relevant articles. No language restriction was applied. The search strategy covered literature from 1980-August 2003. We included studies that were randomized controlled trials (RCTs) comparing progressive resistive exercise interventions with no progressive resistive exercise or another exercise or treatment modality, performed at least three times per week, and lasting at least four weeks among adults (18 years of age or older) living with HIV/AIDS. Data collection forms were used by reviewers to abstract data pertaining to study design, participants, interventions, outcomes and methodological quality from the studies that met inclusion criteria. Whenever possible, meta-analyses were conducted on outcomes using RevMan 4.2.2 computer software. Seven studies met the inclusion criteria for this systematic review. Meta-analysis was limited due to the following differences among the studies: types of exercise interventions, inclusion of co-intervention groups, level of exercise supervision, baseline body composition and testosterone levels of participants, types of outcomes assessed, and methodological quality of the individual studies.Main results indicated that performing progressive resistive exercise or a combination of progressive resistive exercise and aerobic exercise at least three times a week for at least four weeks appears to be safe and may lead to statistically and possibly clinically important increases in body weight and composition. Results also indicate exercise interventions may lead to clinically important improvements in cardiopulmonary fitness. Individual studies included in this review suggest that progressive resistive exercise interventions with or without aerobic exercise also contribute to improvements in strength and psychological status for adults living with HIV/AIDS. Individual studies indicate that progressive resistive exercise or a combination of progressive resistive and aerobic exercise appears to be safe for adults living with HIV/AIDS who are medically stable as a result of no change seen in immunological/virological status. These results are limited to those who continued to exercise and for whom there were adequate follow-up data. Progressive resistive exercise or a combination of progressive resistive exercise and aerobic exercise appear to be safe and may be beneficial for adults living with HIV/AIDS. These findings are limited by the small number of studies that could be included in meta-analyses, small sample sizes and variable participant withdrawal rates among included studies. Future research would benefit from including participants at various stages of HIV infection, a greater proportion of female participants, and participants in a variety of age groups to increase the generalizability of results. Furthermore, future research would benefit from studies with larger sample sizes that conduct an "intention-to-treat" analysis (analysis of participants based on the groups to which they were originally allocated) to better understand outcomes of participants that withdraw from exercise interventions.

Income gains predict cognitive functioning longitudinally throughout later childhood in poor children.

Alleviating disadvantage in low-income environments predicts higher cognitive abilities during early childhood. It is less established whether family income continues to predict cognitive growth in later childhood or whether there may even be bidirectional dynamics. Notably, living in poverty may moderate income-cognition dynamics. In this study, we investigated longitudinal dynamics over 7 waves of data collection from 1,168 children between the ages of 4.6 and 12 years, 226 (19%) of whom lived in poverty in at least 1 wave, as part of the NICHD Study of Early Child Care and Youth Development. Two sets of dual change-score models evaluated, first, whether a score predicted change from that wave to the next and, second, whether change from 1 wave to the next predicted the following score. As previous comparisons have documented, poor children had substantially lower average starting points and cognitive growth slopes through later childhood. The first set of models showed that income scores did not predict cognitive change. In reverse, child cognitive scores positively predicted income change. We speculated that parents may reduce their work investment, thus reducing income gains, when their children fall behind. Second, income changes continued to positively predict higher cognitive scores at the following wave for poor children only, which suggests that income gains and losses continue to be a leading indicator in time of poor children's cognitive performance in later childhood. This study underlined the need to look at changes in income, allow for poverty moderation, and explore bidirectional income-cognition dynamics in middle childhood.

During a primary influenza infection, cytotoxic CD8+ T cells need to infiltrate the infected airways and engage virus-infected epithelial cells. The factors that regulate T cell motility in the infected airway tissue are not well known. To more precisely study T cell infiltration of the airways, we developed an experimental model system using the trachea as a site where live imaging can be performed. CD8+ T cell motility was dynamic with marked changes in motility on different days of the infection. In particular, significant changes in average cell velocity and confinement were evident on days 8-10 during which the T cells abruptly but transiently increase velocity on day 9. Experiments to distinguish whether infection itself or antigen affect motility revealed that it is antigen, not active infection per se that likely affects these changes as blockade of peptide/MHC resulted in increased velocity. These observations demonstrate that influenza tracheitis provides a robust experimental foundation to study molecular regulation of T cell motility during acute virus infection.

Climate change, air pollution, and allergic respiratory diseases: an update.

The rising trend in prevalence of allergic respiratory disease and bronchial asthma, observed over the last decades, can be explained by changes occurring in the environment, with increasing presence of biologic, such as allergens, and chemical atmospheric trigger factors able to stimulate the sensitization and symptoms of these diseases. Many studies have shown changes in production, dispersion, and allergen content of pollen and spores because of climate change with an increasing effect of aeroallergens on allergic patients. Over the last 50 years, global earth's temperature has markedly risen likely because of growing emission of anthropogenic greenhouse gas concentrations. Major changes involving the atmosphere and the climate, including global warming induced by human activity, have a major impact on the biosphere and human environment.Urbanization and high levels of vehicle emissions are correlated to an increase in the frequency of pollen-induced respiratory allergy prevalent in people who live in urban areas compared with those who live in rural areas. Measures of mitigation need to be applied for reducing future impacts of climate change on our planet, but until global emissions continue to rise, adaptation to the impacts of future climate variability will also be required.

Evolution of trends in the live kidney transplant donor-recipient relationship.

2013-01-01

This study examined the changing demographics and age profile between living donors and their recipients. A 46-year review of living donor renal transplants in a single transplant center was performed. The study included 923 consecutive living donor renal transplants from January 1966 until December 2011. These 923 living donor kidneys transplants represent 41% of all transplants performed during this 46-year review. The majority involved sibling donation (39.5%) followed by parent to child (32.5%). Dividing the 46-year timeframe into quartiles, the mean age of donors has remained stable at 39.3 ± 10.9 years. In contrast, the mean age of recipients has trended upwards, from 28 ± 10.7 years in the first quartile (1966-1978) to 37 ± 17.5 years in the latest quartile (2001-2011). This represents an increase every year of approximately 4 months (P < .001). Over the same period, the difference between a given donor's age and their recipient's has decreased every year by approximately 4 months (P < .001). In a linear regression model of donor-recipient categories and their age difference over time, we found that both the child-to-parent and grandchild-to-grandparent groups had the largest effect on the donor-recipient age difference when compared to the classic parent-to-child relationship. This review of center-specific data shows that the difference in the age of the donor to their recipient has been narrowing over time. We have determined that this is primarily due to changes in donor-recipient demographics with an increasing number of younger donors to older recipients. Although the medical risks to donors living with a single kidney have yet to be shown different than that of the general population, the increasing volume of donors who are younger and those with no relation to the recipient should prompt closer follow-up within the transplantation medical community.

This study investigated differences in the development of heavy drinking and marijuana use among students in urban and rural areas and assessed whether any such differences can be accounted for by locality differences in racial/ethnic makeup, social disorganization/low social bonding, feelings of despondency and escapism, and the availability of drugs. Drawn from 62 South Dakota middle schools involved in a drug prevention field trial, participating students were assigned to a locality category based on the location of their seventh-grade school. Schools in metropolitan areas were distinguished from schools in nonmetropolitan areas. Schools in nonmetropolitan areas were further distinguished into those in micropolitan (medium and large towns) and noncore (rural areas without towns and with small towns) areas. We used latent growth curve analysis to model the influence of locality on the development of heavy drinking and marijuana use from ages 13 to 19 and to determine whether differences in development across locality were attributable to location-based differences in race/ethnicity, social disorganization/bonding, feelings of despondency and escapism, and alcohol and marijuana availability. Heavy drinking increased at a faster rate among youth living in micropolitan areas compared with youth living in metropolitan areas. Marijuana use increased at a faster rate among youth living in metropolitan and micropolitan areas compared with youth living in noncore areas. Differences in the rate of change in heavy drinking were attributable to differences in the racial/ethnic composition of metropolitan and micropolitan areas. Differences in the rate of change in marijuana use were attributable to differences in residential instability and marijuana availability. This study underscores the diversity of drug use within rural communities, suggesting that living in a very rural area is protective against some forms of drug use but that living in a rural area that includes a medium or large town is not.

The aim of this study was to identify relevance of subclinical pathological findings in the kidneys of living donors and correlate these with early graft renal function. This was a prospective study on 84 living donor kidney transplant recipients over a period of two years. In all the donors, cortical wedge biopsy was taken and sent for assessment of glomerular, mesangial, and tubule status. The graft function of patients with normal histology was compared with those of abnormal histological findings at one, three, and six months, and one year post-surgery. Most abnormal histological findings were of mild degree. Glomerulosclerosis (GS, 25%), interstitial fibrosis (IF, 13%), acute tubular necrosis (ATN 5%), and focal tubal atrophy (FTA, 5%) were the commonly observed pathological findings in zero-hour biopsies. Only those donors who had histological changes of IF and ATN showed progressive deterioration of renal function at one month, three months, six months, and one year post-transplantation. In donors with other histological changes, no significant effect on graft function was observed. Zero-hour cortical biopsy gave us an idea of the general status of the donor kidney and presence or absence of subclinical pathological lesions. A mild degree of subclinical and pathological findings on zero-hour biopsy did not affect early graft renal function in living donor kidney transplantation. Zero-hour cortical biopsy could also help in discriminating donor-derived lesions from de novo alterations in the kidney that could happen subsequently.

Glacial - interglacial changes of northwest Pacific stratification, inferred from deep and shallow living radiolarians

NASA Astrophysics Data System (ADS)

Hays, J. D.

2009-12-01

Shallow (0-200m) and deep (200 to1000m) living radiolarian flux is used to measure past production from within discrete intervals of the ocean’s water column. Deep-living faunas can also be used as proxies for export production, for they remineralize it and respond geographically and temporally to varying export. Few members of the mesopelagic community leave a fossil record, but of those that do, radiolarians are the most abundant and diverse group. In northwest Pacific late Pleistocene (glacial) sediments, deep-living radiolarian flux dominates over shallow-living flux, but the reverse is true in Holocene sediments, with the dramatic dominance change occurring across the Pleistocene-Holocene boundary. Changing primary productivity can’t cause these flux changes, for shallow-living faunas have access to the same carbon flux as do deep-living faunas, but rather they signal a major reorganization of the radiolarian fauna within the water column and suggest greater glacial than Holocene carbon export. In the Holocene world-ocean, the only region where deep-living radiolarian flux dominates over shallow-living flux is in the Sea of Okhotsk, suggesting environmental similarities between this sea and the northwest Pacific. In winter, cold Siberian air chills the upper hundred meters of the Sea of Okhotsk, promoting the spread of vast sea ice fields. High productivity in a thin (10-15m) summer mixed layer depletes nutrients Between 15 and about 150m exists a layer of cold (-1 to 0 degrees C.) intermediate water, within which radiolarian concentrations are low, but these concentrations increase between 200 and 500m in warmer intermediate water (Nimmergut and Abelmann, 2002). This radiolarian stratification results in greater deep- than shallow-living radiolarian flux to the sea floor. A similar water structure in the glacial northwest Pacific is the probable cause of similar flux patterns between the glacial northwest Pacific and Holocene Sea of Okhotsk. If so then cold glacial northwest Pacific intermediate water promoted the southward spread of sea ice. This inference is supported by the near coincidence of the southern limit of deep-living species dominated glacial sediments and extensive ice rafting. It also explains nutrient depleted glacial northwest Pacific surface waters inferred from isotopic data.

South Korea's low birth rate, aging society, and female migration to urban areas due to industrialization have caused an accelerated inflow of Asian female immigrants into Korea to marry Korean men, especially in rural areas. This study was performed to determine how family function of multicultural families changes over time and what factors affect the changes in family function of multicultural families. The study subjects were 62 Asian immigrant women married to South Korean men living in South Korea. In a 1st wave study in August 2008, the socioeconomic factors and Family Adaptability and Cohesion Scale III (FACES III) scores were measured. A 3-year follow-up study was then conducted in August 2011, and the results were compared with the 1st wave study results. The mean family adaptability score was 24.6 in the 1st wave study and 26.1 at the 3-year follow-up. The average family cohesion score was 31.0 in the 1st wave study and 36.7 at the 3-year follow-up. There was a statistically significant increase in family cohesion after 3 years (P < 0.001). In multiple regression analysis, age difference between husband and wife (P = 0.019) and subjective SES (P < 0.001) were found to be significantly correlated with positive changes of cohesion scores. Family adaptability did not change over time; however, conversely, family cohesion increased. The age difference between husband and wife and the subjective SES had a positive association with the changes in family cohesion. Copyright © 2013 Wiley Publishing Asia Pty Ltd.

We review and compare four broad categories of spatially-explicit modelling approaches currently used to understand and project changes in the distribution and productivity of living marine resources including: 1) statistical species distribution models, 2) physiology-based, biophysical models of single life stages or the whole life cycle of species, 3) food web models, and 4) end-to-end models. Single pressures are rare and, in the future, models must be able to examine multiple factors affecting living marine resources such as interactions between: i) climate-driven changes in temperature regimes and acidification, ii) reductions in water quality due to eutrophication, iii) the introduction of alien invasive species, and/or iv) (over-)exploitation by fisheries. Statistical (correlative) approaches can be used to detect historical patterns which may not be relevant in the future. Advancing predictive capacity of changes in distribution and productivity of living marine resources requires explicit modelling of biological and physical mechanisms. New formulations are needed which (depending on the question) will need to strive for more realism in ecophysiology and behaviour of individuals, life history strategies of species, as well as trophodynamic interactions occurring at different spatial scales. Coupling existing models (e.g. physical, biological, economic) is one avenue that has proven successful. However, fundamental advancements are needed to address key issues such as the adaptive capacity of species/groups and ecosystems. The continued development of end-to-end models (e.g., physics to fish to human sectors) will be critical if we hope to assess how multiple pressures may interact to cause changes in living marine resources including the ecological and economic costs and trade-offs of different spatial management strategies. Given the strengths and weaknesses of the various types of models reviewed here, confidence in projections of changes in the distribution and productivity of living marine resources will be increased by assessing model structural uncertainty through biological ensemble modelling.

Climate change is a global issue in this century which has challenged the survival of living creatures affecting the life supporting systems of the earth: atmosphere, hydrosphere and lithosphere. Scientists have reached in a consensus that climate change is happening. The anthropogenic emission of greenhouse gases is responsible for global warming and therefore climate change. Climate change may directly or indirectly affect human health through a range of pathways related to temperature and precipitation. The aim of this article is to share knowledge on how climate change can affect public health in Nepal based on scientific evidence from global studies and experience gained locally. In this review attempt has been made to critically analyze the scientific studies as well as policy documents of Nepalese Government and shed light on public health impact of climate change in the context of Nepal. Detailed scientific study is recommended to discern impact of climate change on public health problems in Nepal.

Altruistic aging: The evolutionary dynamics balancing longevity and evolvability.

PubMed

Herrera, Minette; Miller, Aaron; Nishimura, Joel

Altruism is typically associated with traits or behaviors that benefit the population as a whole, but are costly to the individual. We propose that, when the environment is rapidly changing, senescence (age-related deterioration) can be altruistic. According to numerical simulations of an agent-based model, while long-lived individuals can outcompete their short lived peers, populations composed of long-lived individuals are more likely to go extinct during periods of rapid environmental change. Moreover, as in many situations where other cooperative behavior arises, senescence can be stabilized in a structured population.

Somerville, Massachusetts, an ethnically diverse, urban community northwest of Boston, presents opportunities and challenges for active living. With a dense street grid, well-maintained sidewalks, neighborhood parks, and existing Community Path, Somerville is very walkable. However, two major surface arteries traverse and bisect neighborhoods, creating pedestrian safety and environmental justice issues. Major goals included promoting increased collaboration and communication among existing active-living efforts; managing the Community Path extension project; encouraging Portuguese-speaking adults to incorporate daily physical activity; leveraging existing urban planning work to establish secure, attractive walking/biking corridors; and embedding active-living messages in everyday life. The Somerville Active Living by Design Partnership (ALbD) successfully created a robust task force that was integrated with citywide active-living efforts, secured resources to increase infrastructure and support for active living, including city-level coordinator positions, and changed decision-making practices that led to incorporation of pedestrian and bicycle transportation priorities into city planning and that influenced the extension of the Community Path. Partnerships must employ sustainability planning early on, utilize skilled facilitative leaders to manage leadership transitions, and engage new partners. Identifying, cultivating, and celebrating champions, especially those with political power, are critical. Working closely with research partners leads to rich data sources for planning and evaluation. Changing the built environment is difficult; working toward smaller wins is realistic and achievable. The synergy of ALbD and other community interventions created a foundation for short-term successes and accelerated political-cultural changes already underway with respect to active living.

This study aimed to explore the experiences of adolescents from Singapore, aged 10-18 years old, living with cancer and their perceptions on how their psychosocial outcomes can be improved. A descriptive qualitative study design was used. Convenience sampling was used to recruit 10 participants from a pediatric oncology ward in a Singapore hospital. Individual semi-structured interviews were conducted. Thematic analysis was used to analyze the data. Five major themes emerged: (1) experience of physical symptoms, (2) emotional response to their condition, (3) changes in social dynamics, and (4) falling behind in academics. The psychosocial outcomes of Singaporean adolescents with cancer could be improved by thorough pain assessments and creating a more conducive hospital environment.

Davis, Gail C; White, Terri L

2008-12-01

The purpose of this study was to test a pain management intervention that integrates goal setting with older adults (age > or =65) living independently in residential settings. This preliminary testing of the Goal Attainment Pain Management Program (GAPMAP) included a sample of 17 adults (mean age 79.29 years) with self-reported pain related to arthritis. Specific study aims were to: 1) explore the use of individual goal setting; 2) determine participants' levels of goal attainment; 3) determine whether changes occurred in the pain management methods used and found to be helpful by GAPMAP participants; and 4) determine whether changes occurred in selected pain-related variables (i.e., experience of living with persistent pain, the expected outcomes of pain management, pain management barriers, and global ratings of perceived pain intensity and success of pain management). Because of the small sample size, both parametric (t test) and nonparametric (Wilcoxon signed rank test) analyses were used to examine differences from pretest to posttest. Results showed that older individuals could successfully participate in setting and attaining individual goals. Thirteen of the 17 participants (76%) met their goals at the expected level or above. Two management methods (exercise and using a heated pool, tub, or shower) were used significantly more often after the intervention, and two methods (exercise and distraction) were identified as significantly more helpful. Two pain-related variables (experience of living with persistent pain and expected outcomes of pain management) revealed significant change, and all of those tested showed overall improvement.

Cognitive impairment places older adults at high risk of functional disability in their daily-life activities, and thus affecting their quality of life. This study aimed to examine the effects of Tai Chi on general cognitive functions and instrumental activities of daily living (IADL) in community-dwelling older people with mild cognitive impairment (MCI) in Hong Kong. The study adopted a multi-site nonequivalent control-group pretest-posttest design. 160 community-dwelling older people, aged ≥60, with MCI, from four community elderly centers participated in the study. The intervention group (IG, n = 80) received training in the Yang-style simple form of Tai Chi, at a frequency of two lessons per week for 16 weeks. Each lesson lasted for one hour. The control group (CG, n = 80) had no treatment regime and joined different recreational activity groups in community centers as usual within the study period. Outcome measures included measures of global cognitive status and IADL. The Chinese version of the Mini-Mental State Examination (CMMSE) was used for global cognitive assessment. The Hong Kong Chinese version of Lawton's Instrumental Activities of Daily Living (IADL-CV) was used to assess the participants' IADL levels. General Estimating Equations (GEE) was used to examine each of the outcome variables for the two groups at the two study time points (the baseline and at the end of the study). Meanwhile, minimum detectable change (MDC) was calculated to estimate the magnitude of changes required to eradicate the possibility of measurement error of outcome measures. Seventy four participants in the IG and 71 participants in the CG completed the study. With adjustments for differences in age, education, marital status and living conditions, the findings revealed that the participants in the IG scored significantly better on the CMMSE test (P = 0.001), and the instrumental ADL questionnaire (P = 0.004). However, those scores changes did not exceed the limits of the respective MDCs in the study, the possibility of measurement variation due to error could not be excluded. Tai Chi may be an effective strategy to enhance cognitive health and maintain functional abilities in instrumental ADL in older people with MCI.

Flourish or flush: effects of simulated extreme rainfall events on Sphagnum-dwelling testate amoebae in a subarctic bog (Abisko, Sweden).

2013-01-01

Extreme precipitation events are recognised as important drivers of ecosystem responses to climate change and can considerably affect high-latitude ombrotrophic bogs. Therefore, understanding the relationships between increased rainfall and the biotic components of these ecosystems is necessary for an estimation of climate change impacts. We studied overall effects of increased magnitude, intensity and frequency of rainfall on assemblages of Sphagnum-dwelling testate amoebae in a field climate manipulation experiment located in a relatively dry subarctic bog (Abisko, Sweden). The effects of the treatment were estimated using abundance, species diversity and structure of living and empty shell assemblages of testate amoebae in living and decaying layers of Sphagnum. Our results show that increased rainfall reduced the mean abundance and species richness of living testate amoebae. Besides, the treatment affected species structure of both living and empty shell assemblages, reducing proportions of hydrophilous species. The effects are counterintuitive as increased precipitation-related substrate moisture was expected to have opposite effects on testate amoeba assemblages in relatively dry biotopes. Therefore, we conclude that other rainfall-related factors such as increased infiltration rates and frequency of environmental disturbances can also affect testate amoeba assemblages in Sphagnum and that hydrophilous species are particularly sensitive to variation in these environmental variables.

Modulation of the response to stress factors of Xerolycosa nemoralis (Lycosidae) spiders living in contaminated environments.

The rapid development of industry has caused widespread pollution in the environment, which has a negative impact on living organisms. Spiders belong to the group of animals that can exist in these anthropogenically changed areas. This is probably due to the development of tolerance mechanisms in these organisms. The impact of long-term pollution on the development of the pre-adaptation to various stress factors in spiders is unknown. In this paper, we show that living in polluted areas affects the modulation of the response to other stress factors through changes in the Hsp70 level. We observed a positive reaction to heat shock in all of the experimental groups, which was expressed by an increase in Hsp70 synthesis compared to the control. The analysis of the protein level, which was a manifestation of the pre-adaptation, was dependent on the degree of pollution on the study sites, the sexes and the type of bioassay that was performed. Our results demonstrate the reaction of spiders living in contaminated areas to the presence of additional stressors. We anticipate our results will be another voice in the discussion on the use of Hsp70 as a stress biomarker in environmental biomonitoring. Copyright © 2016 Elsevier Inc. All rights reserved.

Monitoring of live cell cultures during apoptosis by phase imaging and Raman spectroscopy

Non-invasive live cell measurements are an important tool in biomedical research. We present a combined digital holography/Raman spectroscopy technique to study live cell cultures during apoptosis. Digital holographic microscopy records an interference pattern between object and reference waves, so that the computationally reconstructed holographic image contains both amplitude and phase information about the sample. When the phase is mapped across the sample and converted into height information for each pixel, a three dimensional image is obtained. The measurement of live cell cultures by digital holographic microscopy yields information about cell shape and volume, changes to which are reflective of alterations in cell cycle and initiation of cell death mechanisms. Raman spectroscopy, on the other hand, is sensitive to rotational and vibrational molecular transitions, as well as intermolecular vibrations. Therefore, Raman spectroscopy provides complementary information about cells, such as protein, lipid and nucleic acid content, and, particularly, the spectral signatures associated with structural changes in molecules. The cell cultures are kept in the temperature-controlled environmental chamber during the experiment, which allows monitoring over multiple cell cycles. The DHM system combines a visible (red) laser source with conventional microscope base, and LabVIEW-run data processing. We analyzed and compared cell culture information obtained by these two methods.

Many countries are confronting climate change that threatens agricultural production and farmers' lives. Farmers' perceived risks of climate change and factors influencing those perceived risks are critical to their adaptive behavior and well-planned adaptation strategies. However, there is limited understanding of these issues. In this paper, we attempt to quantitatively measure farmers' perceived risks of climate change and explore the influences of risk experience, information, belief in climate change, and trust in public adaptation to those perceived risks. Data are from structured interviews with 598 farmers in the Mekong Delta. The study shows that perceived risks to production, physical health, and income dimensions receive greater priority while farmers pay less attention to risks to happiness and social relationships. Experiences of the events that can be attributed to climate change increase farmers' perceived risks. Information variables can increase or decrease perceived risks, depending on the sources of information. Farmers who believe that climate change is actually happening and influencing their family's lives, perceive higher risks in most dimensions. Farmers who think that climate change is not their concern but the government's, perceive lower risks to physical health, finance, and production. As to trust in public adaptation, farmers who believe that public adaptive measures are well co-ordinated, perceive lower risks to production and psychology. Interestingly, those who believe that the disaster warning system is working well, perceive higher risks to finance, production, and social relationships. Further attention is suggested for the quality, timing, and channels of information about climate change and adaptation.

Changing the built environment to promote active lifestyles requires collaboration among diverse sectors. Multisectoral collaborative groups in the United States promote active lifestyles through environmental and policy changes. The objective of this study was to examine the characteristics of these collaborative groups and the extent to which they have achieved change. We identified, recruited, and interviewed the coordinators of active living collaborative groups in the United States. We used descriptive statistics to characterize groups by composition, stakeholder engagement, and the extent of environmental and policy change in 8 strategic areas. Fifty-nine groups from 22 states participated in the study. Most groups had a diverse set of partners and used a range of activities to advance their agendas. Most groups achieved some form of environmental or policy change. On average, groups reported working on 5 strategy areas; parks and recreation (86%) and Safe Routes to School (85%) were named most frequently. More than half of groups reported their environmental initiatives as either in progress or completed. Groups reported the most success in changing policy for public plazas, street improvements, streetscaping, and parks, open space, and recreation. Complete Streets policy and zoning ordinances were the most frequently cited policy types. Engaging in media activities and the policy-making process in addition to engaging stakeholders appear to influence success in achieving change. Although many groups successfully worked on parks and recreation improvements, opportunities remain in other areas, including transit and infill and redevelopment. Additional time and resources may be critical to realizing these types of changes.

Molecular Probes: A Tool for Studying Toxicity of VOCs to P.Putida F1

Singh, R.; Olson, M. S.

2007-12-01

Volatile Organic Compounds (VOCs) are of great concern in ground water remediation, and are generally present in the form of NAPLs in subsurface environments. Among the various treatment technologies, in situ bioremediation is one of the most effective and low-cost treatment options. Many soil bacteria are reported to degrade these organic contaminants via metabolism (using them as a source of carbon to derive energy) or co- metabolism up to certain concentrations. However, larger concentrations of these contaminants are toxic to bacteria. Thus, in order to achieve successful bioremediation, it is important to determine the optimal concentrations of various contaminants that is beneficial for the activity and survival of degrading bacteria. The purpose of this study is to develop a novel method for toxicity analyses of VOC contaminants to the soil bacteria that degrade them. The present study is based on a two-color fluorescence assay of bacterial viability which facilitates actual counting of live and dead bacteria. Pseudomonas putida F1 cells were labeled with a LIVE/DEAD® BacLightTM bacterial viability kit (Invitrogen), which consists of a mixture of two dyes, SYTO 9 and propidium iodide, each with a different ability to penetrate healthy bacterial cells. Live cells stain green whereas propidium iodide (red dye) only penetrates cells with compromised membranes that are considered dead or dying. Stained cells were exposed to different concentrations of trichloroethylene (TCE) and toluene in sealed vials. Change in the concentrations of green and red cells were monitored over the time using fluorescence microscopy. UTHSCSA ImageTool software was used to count the live and dead cells in the images. It was observed that live (green) cell concentrations decreased and dead/damaged (red) cell concentrations increased over time when cells were exposed to TCE. No significant changes were observed in control experiments. Death rate constants calculated based on live cell disappearance and dead/damaged cell appearance were found to be approximately equal for TCE. Results will be presented in terms of dose response and death rate curves. Death rate constants and minimum inhibitory concentrations for survival of P. Putida F1 exposed to TCE and toluene will be compared.

Memory for Lectures: How Lecture Format Impacts the Learning Experience

The present study investigated what impact the presentation style of a classroom lecture has on memory, mind wandering, and the subjective factors of interest and motivation. We examined if having a professor lecturing live versus on video alters the learning experience of the students in the classroom. During the lectures, students were asked to report mind wandering and later complete a memory test. The lecture format was manipulated such that all the students received two lectures, one live and one a pre-recorded video. Results indicate that lecture format affected memory performance but not mind wandering, with enhanced memory in the live lectures. Additionally, students reported greater interest and motivation in the live lectures. Given that a single change to the classroom environment, professor presence, impacted memory performance, as well as motivation and interest, the present results have several key implications for technology-based integrations into higher education classrooms.

The effect of air pollution on total phyllospheric microflora from two species of the epiphytic neotropical genus Tillandsia (Bromeliaceae) was studied by comparing unpolluted plants living in a forest (Escazú, San José) with polluted ones from an urban site of Costa Rica (San José city). Dilutions of homogenized leaf samples were plated on media suitable for each microbial group. For each microorganism group, total counts were performed and purified strains of randomly chosen colonies were identified. There was a global reduction in the number of living microorganisms due to pollution effects, especially yeasts and bacteria, while nitrogen-fixing microorganisms and fungi were less affected. Our results showed that the phyllosphere microflora of Tillandsia plants living in a tropical urban environment changes in terms of number and species composition of yeasts and bacteria with respect to plants living in unpolluted environment.

Coral reefs are threatened by climate change as coral-algal symbioses are currently living close to their upper thermal limits. The resilience of the algal partner plays a key role in determining the thermal tolerance of the coral holobiont and therefore, understanding the acclimatory limits of present day coral-algal symbioses is fundamental to forecasting corals' responses to climate change. This study characterised the symbiont community in a highly variable and thermally extreme (Max = 37.5 °C, Min = 16.8 °C) lagoon located in the southern Persian/Arabian Gulf using next generation sequencing of ITS2 amplicons. Despite experiencing extreme temperatures, severe bleaching and many factors that would be expected to promote the presence of, or transition to clade D dominance, the symbiont communities of the lagoon remain dominated by the C3 variant, Symbiodinium thermophilum. The stability of this symbiosis across multiple genera with different means of symbiont transmission highlights the importance of Symbiodinium thermophilum for corals living at the acclimatory limits of modern day corals. Corals in this extreme environment did not undergo adaptive bleaching, suggesting they are living at the edge of their acclimatory potential and that this valuable source of thermally tolerant genotypes may be lost in the near future under climate change.

Comparative analyses of fecal microbiota in Tibetan and Chinese Han living at low or high altitude by barcoded 454 pyrosequencing

Knowledge about the impact of altitude and ethnicity on human gut microbiota is currently limited. In this study, fecal microbiota from 12 Tibetans (T group), 11 Chinese Han living in Tibet (HH group) and 12 Chinese Han living in Shaanxi province (LH group) were profiled by 454 pyrosequencing. Analysis of UniFrac principal coordinates showed significant structural changes in fecal microbiota among the three groups. There were significant differences in the composition of fecal microbiota among the three groups at phylum and genus levels. At the phylum level, the fecal samples of HH and T groups had higher relative abundances of Firmicutes, whereas the LH group had a higher relative abundance of Bacteroidetes. These changes at the phylum level reflected different dominant genus compositions. Compared with the LH group, changes of Firmicutes and Bacteroidetes were mainly due to a significant decrease of Prevotella in the HH group and were primarily attributable to significant decreases of Bacteroides and Prevotella as well as a significant increase of Catenibacterium in the T group. In conclusion, our results suggest that high altitude may contribute to shaping human gut microbiota. Genetic and dietary factors may also explain the different microbiota compositions between Tibetan and Chinese Han. PMID:26443005

We have utilized Raman tweezers to measure and assign micro-Raman spectra of optically trapped, live red blood cells (RBCs), white blood cells (WBCs) and platelets. Various types of WBCs- both granulocytes, lymphocytes, and their different types have been studied. The Raman bands are assigned to different biomolecules of blood cells. The Raman spectra thus obtained has been enabled detection of β-carotene in these blood cells, the spectral features of which act as a signature that facilitates experimental probing of the effect of 785nm laser light on different blood cells as a function of incident laser power in the mW range. The spectral changes that we obtain upon laser irradiation indicate that, both haemoglobin as well as the cell membrane sustains damage. In case of lymphocytes and platelets the peaks corresponding to β-carotene showed drastic changes. Thorough analysis of the spectral changes indicates possibility of free radical induced damage of β-carotene in lymphocytes and platelets. Among different blood cells, RBCs have a power threshold of only 10mW. The power threshold for other types of blood cells is somewhat higher, but always below about 30mW. These values are likely to serve as useful guides for Raman tweezers based experiments on live cells. Copyright © 2017. Published by Elsevier B.V.

We examined whether living in neighborhoods supportive of healthier diets and more active lifestyles may buffer immigrants against the unhealthy weight gain that is purported to occur with longer length of US residence. Neighborhood data referring to a 1-mile buffer around participants' baseline home addresses were linked to longitudinal data from 877 Hispanic and 684 Chinese immigrants aged 45 to 84 years in the Multi-Ethnic Study of Atherosclerosis. We used ethnicity-stratified linear mixed models to examine whether food and activity-based neighborhood measures (healthy food stores, walkability, and recreational facilities) were associated with change in waist circumference (WC) over a 9-year follow-up. Among Hispanics, living in neighborhoods with more resources for healthy food and recreational activity was related to lower baseline WC. However, there was no association with change in WC over time. Among Chinese, living in more walkable neighborhoods was associated with lower baseline WC and with slower increases in WC over time, especially among the most recent immigrant arrivals. Where immigrants reside may have implications for health patterns that emerge with longer time in the United States. Copyright © 2015 Elsevier Inc. All rights reserved.

Active travel to school (ATS) is positively associated with various health indicators. The rapid social, economic, and environmental changes in China provide a unique setting to study changes and predictors of ATS over time. Using logistic regression modeling, we analyzed data from the China Health and Nutrition Survey during 1997 to 2011 (N = 9487, ages 6 to 17 years) to estimate the change over time in ATS and to identify associated factors. The prevalence of reported ATS among children dropped from 95.8% in 1997 to 69.3% in 2011. ATS was common in children living closer to school, in middle school, from low-income households, with low parental education status, and those without a private vehicle. Children who were living in a metropolitan area and who had more than 40 minutes of total PA per day were less likely to report ATS. The decrease of ATS had been concurrent with the increase of the children living at a longer distance from school and the increase of household owning private vehicles which were associated with the rapid urbanization and economic growth in China. Factors associated with the decreased ATS in China are similar to other countries but the underlying reasons may be different.

The aim of this paper is to assess the impact of living in Saudi Arabia on expatriate employees and their families' behavioural cardiovascular risk factors (BCVRFs), and to examine the association between changes in BCVRFs and metabolic syndrome (MetS). A cross-sectional study was conducted on 1437 individuals, aged ≥ 18 years, from King Saud University in Riyadh, Saudi Arabia. We used the World Health Organization STEPS questionnaire to ask every participant questions about BCVRFs twice: (1) to reflect their period of living in Saudi Arabia and (2) to shed light upon life in their country of origin. Their mean age was 40.9 (11.7) years. The prevalence of BCVRFs was as follows: tobacco use in 156 (11%), physical inactivity in 1049 (73%) low intake of fruit and vegetables in 1264 (88%) and MetS in 378 (26%). Residing in Saudi Arabia had reduced physical activity and intake of fruit and vegetables. There was also a significant increase in the fast food consumption. In conclusion, living in Saudi Arabia had a significant negative effect on BCVRFs. However, there was no statistically significant association between changes in fruit and vegetable intake and physical activity and MetS status, except that intake of fast food was lower among participants with MetS.

Detecting long-term temporal trends in sediment-bound trace metals from urbanised catchments.

The shift from rural lifestyles to urban living has dramatically altered the way humans interact and live across the globe. With over 50% of the world's populations living within cities, and significant increases expected over the next 50 years, it is critical that changes to social, economic and environmental sustainability of cities globally be implicit. Protecting and enhancing aquatic ecosystems, which provide important ecosystem services, is challenging. A number of factors influence pollutants in urban waterways including changes in land-use, impervious area and stormwater discharges, with sediment-bound pollution a major issue worldwide. This work aimed to investigate the spatial and temporal distribution of trace metals in freshwater sediments from six urbanised catchment over a 30-year period. It provides an estimate of pollution using a geoaccumulation index and examines possible toxicity using a probable effect concentration quotient (mPECq). Results showed significant temporal changes in metal concentrations over time, with lead generally decreasing in all but one of the sites, attributed to significant changes in environmental policies and the active elimination of lead products. Temporal changes in other metals were variable and likely dependent on site-specific factors. While it is likely that diffuse pollution is driving changes in zinc, for metals such as lead, chromium and copper, it is likely that watershed landuse and/or point sources are more important. The results clearly indicated that changes to watershed landuse, environmental policy and pollution abatement programs are all driving changes in sediment quality, highlighting the utility of long-term sediment monitoring for assessment of urban watershed condition. While this study has demonstrated the utility of detecting long-term changes in metal concentrations, this approach could easily be adapted to detect and assess future trends in other hydrophobic contaminants and emerging chemicals of concern, such as synthetic pyrethroids, providing essential information for the protection of catchment.

Climate change exacerbates the environmental condition directly or indirectly. The frequency of climate-related disasters worldwide has been on the increase with their amplitude growing. The consequences of climate-related disaster are not limited to loss of lives and properties alone, but also serious repercussions on post-disaster reconstruction, as well as the cost implications for resilience of the infrastructure and natural environment. In developing countries, the low-income group whose income is below the world poverty line is the most vulnerable to the dangers of climate change. To worsen the case, the political and economic strength of these countries in terms of economic resources, technological development and urban planning management necessary for adapting to climate change are relatively weak. This study takes an inventory of the study area environment to establish its environmental state in terms of the extent of its vulnerability and economic strength. It was found that the study area is vulnerable being a coastal area and could be described as a slum settlement. Also, information on frequency and extent of flooding in association with change in temperature was collected. The results show that the frequency of flood occurrence within the period has increased and the increase was attributed to rise in sea level alongside a significant increase in temperature within the period of study. The implications of the findings on loss of lives/properties and continuous decline in the area economic strength as it relates to resilience of the area was discussed. The study suggests an effective urban land use management and control, as well as redevelopment of resilient infrastructure in the area. The study concludes that the increase in temperature for the period as an indicator of climate change causes rise in sea level and the subsequent increase in flooding occurrence. Key Words: Ecologically Fragile Zone, Climate Change, Flooding and Vulnerability.

Rationale Transverse tubules (TTs) couple electric surface signals to remote intracellular Ca2+ release units (CRUs). Diffraction-limited imaging studies have proposed loss of TT components as disease mechanism in heart failure (HF). Objectives Objectives were to develop quantitative super-resolution strategies for live-cell imaging of TT membranes in intact cardiomyocytes and to show that TT structures are progressively remodeled during HF development, causing early CRU dysfunction. Methods and Results Using stimulated emission depletion (STED) microscopy, we characterized individual TTs with nanometric resolution as direct readout of local membrane morphology 4 and 8 weeks after myocardial infarction (4pMI and 8pMI). Both individual and network TT properties were investigated by quantitative image analysis. The mean area of TT cross sections increased progressively from 4pMI to 8pMI. Unexpectedly, intact TT networks showed differential changes. Longitudinal and oblique TTs were significantly increased at 4pMI, whereas transversal components appeared decreased. Expression of TT-associated proteins junctophilin-2 and caveolin-3 was significantly changed, correlating with network component remodeling. Computational modeling of spatial changes in HF through heterogeneous TT reorganization and RyR2 orphaning (5000 of 20 000 CRUs) uncovered a local mechanism of delayed subcellular Ca2+ release and action potential prolongation. Conclusions This study introduces STED nanoscopy for live mapping of TT membrane structures. During early HF development, the local TT morphology and associated proteins were significantly altered, leading to differential network remodeling and Ca2+ release dyssynchrony. Our data suggest that TT remodeling during HF development involves proliferative membrane changes, early excitation-contraction uncoupling, and network fracturing. PMID:22723297

The purpose of this study was to determine the effect of a conservative regimen for the treatment of constipation in persons living with a colostomy. Prospective, noncontrolled, single-center study. The study sample comprised 35 patients with a colostomy who were diagnosed with constipation. Subjects with morphologic changes causing constipation such as stomal stenosis and neoplastic and inflammatory changes were excluded. The study was conducted in the Proctology and Stoma Outpatient Clinic at Poznan University of Medical Sciences. Patients at our Stoma Outpatient Clinic underwent baseline evaluation, and those with symptoms of constipation (prolonged periods between bowel movements, passage of pasty or hardened fecal effluent, and associated symptoms such as abdominal discomfort or bloating, flatulence, and pain with passage of effluent into the stoma) received individualized dietary recommendations that typically included an increase in dietary fiber and fluid intake, along with increased fluid intake. The outcomes of dietary changes were evaluated during a follow-up visit 3 months later. If dietary changes alone did not improve constipation symptoms, we prescribed a psyllium-based bulk-forming agent, an osmotic stool softener, and a probiotic, with or without a prokinetic agent such as metoclopramide taken 3 times daily. Dietary interventions alone were deemed successful in 60% of study subjects (n = 21); the remaining 14 patients required additional treatment. Dietary modifications alone relieved constipation in more than half of a group of 35 patients with constipation. We therefore recommend a trial of dietary modifications prior to the initiation of pharmacotherapy in patients with a colostomy.

Currently, a comprehensive program for screening and early detection of cervical cancer does not exist in Iran. This study aimed to determine the prevalence of abnormal Papanicolaou (Pap) smears and some related factors among women living in Zanjan, Iran. This cross-sectional study was conducted in 2012 in Zanjan on 4274 married women aged 20-65 years. The study participants were selected through two-stage cluster sampling. After obtaining written consent, demographic and fertility questionnaires were completed. Samples from cervix were obtained through a standard method using the Rover Cervex- Brush. Evaluation and interpretation of the samples were reported using the Bethesda 2001 method. Data were statistically analyzed using chi-square and logistic regression models. Most inflammatory changes in the samples were mild (37.4%). Abnormal atypical changes in the epithelial cells were found in 4.04%. The highest percentage of abnormal changes in the epithelial cells was atypical squamous cells of undetermined significance (ASCUS) (1.9%). Abnormal results of Pap smear was significantly and independently associated with age, papillomavirus infection, and lack of awareness about Pap smear tests. Given the high prevalence of inflammatory and precancerous changes in this study, compared to other studies in Iran and other Muslim countries, and the effect of demographic variables and individual factors on abnormal results, increasing the awareness of women and their families regarding the risk factors for cervical cancer, preventive measures such as screening, and timely treatment seem necessary.

Background The aim of this study was to assess the main factors related to maternal mortality reduction in large time series available in Chile in context of the United Nations' Millennium Development Goals (MDGs). Methods Time series of maternal mortality ratio (MMR) from official data (National Institute of Statistics, 1957–2007) along with parallel time series of education years, income per capita, fertility rate (TFR), birth order, clean water, sanitary sewer, and delivery by skilled attendants were analysed using autoregressive models (ARIMA). Historical changes on the mortality trend including the effect of different educational and maternal health policies implemented in 1965, and legislation that prohibited abortion in 1989 were assessed utilizing segmented regression techniques. Results During the 50-year study period, the MMR decreased from 293.7 to 18.2/100,000 live births, a decrease of 93.8%. Women's education level modulated the effects of TFR, birth order, delivery by skilled attendants, clean water, and sanitary sewer access. In the fully adjusted model, for every additional year of maternal education there was a corresponding decrease in the MMR of 29.3/100,000 live births. A rapid phase of decline between 1965 and 1981 (−13.29/100,000 live births each year) and a slow phase between 1981 and 2007 (−1.59/100,000 live births each year) were identified. After abortion was prohibited, the MMR decreased from 41.3 to 12.7 per 100,000 live births (−69.2%). The slope of the MMR did not appear to be altered by the change in abortion law. Conclusion Increasing education level appears to favourably impact the downward trend in the MMR, modulating other key factors such as access and utilization of maternal health facilities, changes in women's reproductive behaviour and improvements of the sanitary system. Consequently, different MDGs can act synergistically to improve maternal health. The reduction in the MMR is not related to the legal status of abortion. PMID:22574194

Ensuring access to timely and appropriate primary healthcare for deprived patients is an issue facing all countries, even those with universal healthcare systems. There is a paucity of information on how patients living in a context of material and social deprivation perceive barriers in the healthcare system. This study combines the perspectives of persons living in poverty and of healthcare providers to explore barriers to responsive care for underserved persons with a view to developing equity-focused primary care. In this participatory action research we used photovoice, together with a method known as 'merging of knowledge and practice' developed by ATD Fourth World, an international community organization working to eradicate poverty. The study was conducted in two teaching primary care practices in the Canadian province of Quebec. Participants consisted of 15 health professionals and six members of ATD Fourth World; approximately 60 group meetings were held. Data were analyzed through thematic analysis, in part with the involvement of persons living in poverty. Three main barriers to responsive care in a context of poverty were highlighted by all participants: the difficult living conditions of people living in poverty, the poor quality of interactions between providers and underserved patients, and the complexity of healthcare system organization and functioning. Our research revealed that unhealthy living conditions prevent persons living in poverty from accessing quality healthcare and maintaining good health. Also, the complexity of the healthcare system's organization and functioning has a negative impact on the interactions with healthcare providers. Changes in policy and practice are needed to address those barriers and to achieve greater equity and provide more responsive care for persons living in poverty.

Inclusive research: making a difference to policy and legislation.

While inclusive research has become an important stream in research with people with intellectual disabilities, there is a tension between the possibly empowering research process and the strength of the research itself to make social change happen. In this paper, we explore the contribution of two inclusive qualitative research studies in Australia and the Republic of Ireland to change in policy and legislation. Both studies used qualitative methods including life stories and focus groups to explore the issue of sexuality and relationships. In both studies, people with intellectual disabilities were actively involved in undertaking the research. Both studies revealed that it was difficult for people with intellectual disabilities to express their sexuality openly or to form adult relationships. Both studies were used by people with intellectual disabilities and their supporters to promote change in which they had a heard voice. This paper is about how people with intellectual disabilities and their supporters can use research which they have done to change policies and laws that affect them. When people with intellectual disabilities are doing research it is called inclusive research.We write about two research studies which were about the sexual lives and relationships of people with intellectual disabilities. One research study was in Australia and one was in the Republic of Ireland.In the Australian study, Living Safer Sexual Lives, 25 people with intellectual disabilities told their life stories and talked about sexuality and relationships.In the Irish study people with intellectual disabilities told life stories and talked with other people with intellectual disabilities about their sexuality and relationships in groups. These are called focus groups.In this paper we explore 4 questions that arose from these studies. Question 1. What impact does doing research have on the people who are involved in it? People with intellectual disabilities in Australia were members of the group that guided the research. They were partners in its design, in deciding what questions should be asked about sexuality and relationships., and thinking about what was found out. They became involved in making films about the study. They learned a lot about research, sexuality and relationships and became members of a government committee to change policy about sexuality and people with disabilities. In Ireland people with intellectual disabilities involved in doing the research talked together about their lives. They then talked with 16 groups of people with intellectual disabilities about their relationships and sexuality. They learned about research and about sexuality and developed plays about their experiences. Question 2. To what extent can inclusive research change policy and practice? In Australia the research led to a change in government policy about sexuality and people with disabilities. The new policy clearly stated people with disabilities had rights to relationships and to a sexual life. It set out rights and responsibilities for people with intellectual disabilities and service providers about relationships and sexuality. It took a long time to get a change in policy and people with intellectual disabilities were part of the getting the change to happen. In Ireland there is a law which says that it is illegal to have some forms of sex with people with intellectual disabilities. From the research people with intellectual disabilities became involved in talking with government about changing this law so that it gives them more rights to a sexual life. The law has not changed yet but the voices of people with intellectual disabilities are now being heard. Question 3 When does research shift into being advocacy? How does this happen? People with intellectual disabilities in both studies became advocates to get change to happen. Partly this was because they had become more 'expert' about sexuality and relationships and the policy and law. They were angry at what they had found out in the research and wanted to get change to happen. Question 4 What added value does including people with intellectual disabilities as researchers give to the research? People with intellectual disabilities had knowledge and experience that made it possible for the research in both Australia and Ireland to happen. They were important in how the research was done and what was done with it after it was finished. © 2013 John Wiley & Sons Ltd.

To verify the effect of in-home rehabilitation on quality of life and activities of daily living in elderly clients. In this non-randomized controlled intervention trial, elderly participants were separated into a rehabilitation or a non-rehabilitation group (n = 100 each). The non-rehabilitation group received basic in-home nursing care, including assistance with cooking, cleaning, toileting, meals and medication. The rehabilitation group received a physical treatment program provided by a licensed professional once a week and basic nursing care in the home. For each group, quality of life and activities of daily living were assessed approximately every 3 months over a 1-year period. Quality of life was evaluated using the Philadelphia Geriatric Center Morale Scale, and activities of daily living were evaluated based on the Functional Independence Measure. The rehabilitation group showed statistically significant improvements in both quality of life and activities of daily living. In contrast, the non-rehabilitation group, although showing slight improvement in quality of life at 9 months, showed almost no effects at the other time-points and no significant changes in activities of daily living over the course of the study. The results of the present study suggest that long-term continuous in-home rehabilitation might improve quality of life and activities of daily living in elderly clients.

Kirk, Susan

2010-11-01

Increasing numbers of children need the support of medical technology for their survival and wellbeing, yet little is known about their experiences of living technology-assisted lives. This study aimed to explore how this group of children experience and construct medical technology and its influence on their identity and social relationships. Using a Grounded Theory approach, 28 children/young people aged between 8 and 19 years old and using different types of medical devices were recruited via nursing services in England. Data were collected by in-depth interviews conducted in children's homes. The medical technology occupied an ambivalent position in children's lives being seen as having both an enabling and disabling presence. Children actively engaged in work to incorporate the technology into their lives and bodies by developing strategies to manage their condition, the technology and their identities. This body work appeared to be driven by a desire to 'normalise' their bodies and their lives. Technologies were shaped to integrate them into everyday life and children managed their self-presentation and controlled information about their condition. This work was ongoing, responding to changing social contexts and relationships. For these children the process of 'growing up' involves incorporating disability, illness and technology. This study contributes to knowledge by examining how medical technology is constructed by children whose lives are dependent on it and illuminating the resources and strategies they use to manage their identity and negotiate peer culture interactions and norms.

Learning to live well with chronic fatigue: the personal perspective.

PubMed

Wilson, Lynere; Whitehead, Lisa; Burrell, Beverley

2011-10-01

Persistent fatigue is recognized as an integral and significantly disabling aspect of the experience of living with a long-term health condition. Acute medical care models have limited applicability when seeking to provide health care to meet the needs of those living with chronic fatigue. This article is a report of a study that sought to understand how people can live well in spite of the presence of chronic fatigue. A thematic analysis was conducted on 43 narratives provided by people living with chronic fatigue during 2007 as part of an internet-based study. This report focuses on the two themes that appeared of most relevance to participants: managing energy and redefining self. Two particular approaches to energy management were noted. In the first, the focus is upon moderating and avoiding excess to manage energy. In the second approach, the body was conceptualized as a machine so that energy becomes a limited resource to be managed. Work to redefine the sense of self appeared to be focused upon the desire to seek normality, to see oneself as rational and come to terms with change. People can and do find ways to live well with chronic fatigue. Understanding how the person with chronic fatigue has come to conceptualize his/her experiences will be a more fruitful starting point than providing recipes for successful living if nurses are to work effectively with this group of people. © 2011 Blackwell Publishing Ltd.

Increases in Tolerance within Naturalistic, Self-Help Recovery Homes

Olson, Brad D.; Jason, Leonard A.; Davidson, Michelle; Ferrari, Joseph R.

2011-01-01

Changes in tolerance toward others (i.e., universality/diversity measure) among 150 participants (93 women, 57 men) discharged from inpatient treatment centers randomly assigned to either a self-help, communal living setting or usual after-care and interviewed every 6 months for a 24 month period was explored. Hierarchical Linear Modeling examined the effect of condition (Therapeutic Communal Living versus Usual Care) and other moderator variables on wave trajectories of tolerance attitudes (i.e., universality/diversity scores). Over time, residents of the communal living recovery model showed significantly greater tolerance trajectories than usual care participants. Results supported the claim that residents of communal living settings unit around super-ordinate goals of overcoming substance abuse problems. Also older compared to younger residents living in a house for 6 or more months experienced the greatest increases in tolerance. Theories regarding these differential increases in tolerance, such as social contact theory and transtheoretical processes of change, are discussed. PMID:19838787

This study evaluates changes in physical activity and active transportation associated with installation of new bicycle boulevards. This natural experiment study uses data from a longitudinal panel of adults with children (n=353) in Portland, OR. Activity and active transportation outcomes were measured with GPS and accelerometers worn for up to 5 days in 2010-11 and 2012-13. The effect of the treatment was estimated using difference in differences estimation and multivariate regression models. In five of the seven models, the interaction term was not significant, indicating that after controlling for the main effects of time and exposure separately, there was no correlation between being in a treatment area and minutes of moderate and vigorous physical activity (MVPA) per day, bicycling >10 min, walking >20 min, minutes of walking (if >20), or making a bike trip. Significant covariates included rain, being female, living closer to downtown, and attitudes towards bicycling, walking, and car safety. This study could not confirm an increase in physical activity or active transportation among adults with children living near newly installed bicycle boulevards. Additional pre/post studies are encouraged, as well as research on the length of time after installation that behavior change is likely to occur. Copyright © 2014 Elsevier Inc. All rights reserved.

Some opinions about matter and material substances: from inanimate system -- to living according to A. Einstein general theory of relativity.

PubMed

Topuria, T; Gogebashvili, N; Korsantia, B

2005-11-01

During transformation from inanimate to living, change of the space position of the matter causes the change of the field, as the space does not exist without the field, therefore the time-space as the properties of material substances, should undergo certain changes. The outside inanimate system, in this case a matrix, has its own time. The living system, in this case a cell, where the matter undergoes space conformation with the change of field and space-time, has its own time and it has begun to flow more rapidly than in matrix. From the surface of the body, from different energetic reservoirs oppositely charged matter substances following from special transport systems from the life system transmitted into lifeless one and change their matter space conformation, create transmission gradient that is the gradient border of time from lifeless system into live. In the case of a human, hypothetically, the gradient system of time must be of a complex scheme counting the inter-transformation and interaction gradients of outer and inner abdominal systems. Subconscious and consciousness by means of special links and messages, information selection interact and form unique connection between the systems. Subconscious serves for accelerated time system. Conscious by means of permanent contact with the environment collects and reacts in matrix time system By interconnection of these two systems ideal adaptation with the environment takes place. Time difference gradient system is an additional energy factor, by means of which respective ordered geometrical structures special for the given types are formed. The living organism is an inter-regulated interconnection global system resulting from the changes of matter and material substances space configuration.

To investigate the relationship between changes in clinical rating scale items and endpoint Patient Global Impression of Improvement (PGI-I). Data were pooled from 4 randomized, double-blind, placebo-controlled studies of duloxetine in patients with fibromyalgia (FM). Variables included in the analyses were those that assessed symptoms in FM domains of pain, fatigue, sleep, cognitive difficulties, emotional well-being, physical function, and impact on daily living. The association of endpoint PGI-I with changes from baseline in individual variables was assessed using Pearson product-moment correlations (r). Stepwise linear regression was used to identify those variables for which changes from baseline were statistically significant independent predictors of the endpoint PGI-I ratings. Changes in pain variables and interference of symptoms with the ability to work were highly correlated (r >or= 0.5 or r

Increased boating activity has driven morphological and biological changes along the coasts of estuarine environments. Large, recurrent boat wakes impede the growth of oyster reefs and salt marsh vegetation, which both serve as natural protection against erosion. A NOAA-funded experiment along a section of the Intracoastal Waterway at Guana Tolomato Matanzas National Estuarine Research Reserve (GTMNERR) near St. Augustine, Florida, studies the effectiveness of a living shorelines approach in mitigating the erosional impact of high-energy boat wakes. Living shorelines are a natural shoreline stabilization technique, where plants or organic structures are installed on the coastline. This study utilizes a combination of oyster gabions and porous breakwaters to facilitate oyster growth as well as marsh progradation. We present observations of flow and sediment transport associated with boat activity. Numerical simulations are used to evaluate the performance of the breakwaters and their effectiveness in reducing sediment resuspension and transport on the marsh surface.

Shame and the motivation to change the self.

2014-12-01

A central question of human psychology is whether and when people change for the better. Although it has long been assumed that emotion plays a central role in self-regulation, the role of specific emotions in motivating a desire for self-change has been largely ignored. We report 2 studies examining people's lived experiences of self-conscious emotions, particularly shame, in motivating a desire for self-change. Study 1 revealed that when participants recalled experiences of shame, guilt, or embarrassment, shame-and, to some degree, guilt-predicted a motivation for self-change. Study 2 compared shame, guilt, and regret for events and found that although shame experiences often involved high levels of both regret and guilt, it was feelings of shame that uniquely predicted a desire for self-change, whereas regret predicted an interest in mentally undoing the past and repairing harm done. Implications for motivating behavior change are discussed.

Depressive symptoms can lower adherence and change in dietary studies. Behavioral activation may reduce these effects. This study aims to assess relationships among depressive symptoms on adherence and dietary change in the Women's Healthy Eating and Living (WHEL) Study Secondary analyses from the WHEL Study, which achieved major dietary change in breast cancer survivors (N = 2817), were conducted. Logistic regressions were undertaken of baseline depressive symptoms (six-item Center for Epidemiologic Studies Depression Scale (CES-D)) with (1) completion of 1- and 4-year study assessments and (2) validated change in dietary behavior in the intervention group. In the comparison group (vs. intervention), depressive symptoms lowered completion of dietary recalls and clinic visits [4 years: odds ratio (OR) = 2.0; 95 % confidence interval (CI) = 1.4-3.0]. The behaviorally oriented intervention achieved major change in those furthest from study targets, although changes were lower in those with depressive symptoms: fruit/vegetable (+37.2 %), fiber (+49.0 %), and fat (-22.4 %). Behavioral activation in dietary change interventions can overcome the impact of depressive symptoms.

The seroprevalence of hepatitis A virus (HAV) is changing from high to intermediate endemicity in several Latin American countries, but the pattern in the Andean Latin American countries is unknown. A seroepidemiological survey (n = 436) of HAV in schoolchildren living in the Cochabamba region of Bolivia was conducted in 2010. A questionnaire was completed by parents to obtain demographic, socio-economic, and housing data, and blood samples were collected. The overall prevalence of HAV IgG was 95.4% (95% CI 93.5-97.4). The prevalence was higher in children aged 5-10 years (97%) and pre-adolescents aged 10-13 years (97.9%). The prevalence was also higher in subjects whose parents had a low level of education (99.4-99.5%), who lived in rural areas (98.7%), lived in municipalities with low urban development (99.1-100%), had water delivered at home from a tanker (99.4%), and spoke Quechua at home (99.5%). The descriptive and bivariate analysis suggested that no change in HAV epidemiology has occurred in Cochabamba. Copyright © 2013 Wiley Periodicals, Inc.

Gentrification and preterm birth in New York City, 2008–2010.

PubMed

Huynh, M; Maroko, A R

2014-02-01

Adverse birth outcomes have been linked to neighborhood level socioeconomic status. However, little work has examined the influence of social and economic change over time (i.e., gentrification) on health. This study aims to assess the association between gentrification and preterm birth (PTB) while examining the modifying effect of maternal race/ethnicity and educational attainment. New York City births, 2008–2010, (n=126,165) were linked to a measure of gentrification at the community district level (n=59). The gentrification measure was calculated using percent change in education level, poverty level, and median household income (MHI) between the 2005–2009 American Community Survey and the 1990 Census. PTB was defined as clinical gestational age less than 37 weeks. Generalized estimating equations were utilized to examine the association. Gentrification (i.e., increase in residents with a college education, increase in MHI, and decrease in residents living below the poverty line) was not associated with PTB. However, among Non-Hispanic Blacks, very high gentrification was adversely associated with PTB (AOR, 1.16; 95 % CI, 1.01–1.33) as compared to those who lived in a very low gentrified neighborhood. Among non- Hispanic Whites, living in a very high gentrified neighborhood was protective as compared to living in a very low gentrified neighborhood (AOR, 0.78; 95 % CI, 0.64– 0.94). Although there is a need to develop a more nuanced measure of gentrification, these results indicate that changes in the economic character of a neighborhood may have a significant influence on birth outcomes.

Mapping the change of Phragmites australis live biomass in the lower Mississippi River Delta marshes

2017-07-28

Multiyear remote sensing mapping of the normalized difference vegetation index (NDVI) was carried out as an indicator of live biomass composition of the Phragmites australis (hereafter Phragmites) marsh in the lower Mississippi River Delta (hereafter delta) from 2014 to 2017. Maps of NDVI change showed that the Phragmites condition was fairly stable between May 2014 and July 2015. From July 2015 to April 2016 NDVI change indicated Phragmites suffered a widespread decline in the live biomass proportion.  Between April and September 2016, most marsh remained unchanged from the earlier period or showed improvement; although there were pockets of continued decline scattered throughout the lower delta. From September 2016 to May 2017 a pronounced and widely exhibited decline in the condition of Phragmites marsh again occurred throughout the lower delta. This final NDVI change mapping supported field observations of Phragmites decline during the same period.

Recent advances in biotechnology and imaging technology have provided great opportunities to investigate cellular dynamics. Conventional imaging methods such as transmission electron microscopy, scanning electron microscopy, and atomic force microscopy are powerful techniques for cellular imaging, even at the nanoscale level. However, these techniques have limitations applications in live cell imaging because of the experimental preparation required, namely cell fixation, and the innately small field of view. In this study, we developed a nanoscale optical imaging (NOI) system that combines a conventional optical microscope with a high resolution dark-field condenser (Cytoviva, Inc.) and halogen illuminator. The NOI system's maximum resolution for live cell imaging is around 100 nm. We utilized NOI to investigate the dynamics of intracellular microvesicles of neural cells without immunocytological analysis. In particular, we studied direct, active random, and moderate random dynamic motions of intracellular microvesicles and visualized lysosomal vesicle changes after treatment of cells with a lysosomal inhibitor (NH4Cl). Our results indicate that the NOI system is a feasible, high-resolution optical imaging system for live small organelles that does not require complicated optics or immunocytological staining processes.

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

PubMed

Wirz, Markus; Dietz, Volker

2015-02-01

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

Myocardial infarction (MI) patients may find it challenging to adhere to lifestyle advice and medications. Understanding motivational factors and barriers to change is crucial. However, empirical evidence on patients' ability to effect lifestyle changes at the time of discharge is limited. The aim of this study was to identify at the time of hospital discharge the goals, resources, and barriers to future change in MI patients. We conducted a qualitative interview study with a purposive sample of 20 MI patients (eight women) in a cardiac department at a university hospital in Norway. All interviews were conducted before hospital discharge, transcribed verbatim, and analysed using qualitative content analysis. Three themes suggested that, at the time of discharge, patients' views of their MI were complex and diverse. Patients were motivated to change their lifestyle and contemplated taking their life in new directions, adopting a change of life perspective. Frequently, patients struggled to understand the context of living with an MI, manage symptoms, and understand the precipitating causes of MI. There were also patients who wanted to maintain their present lifestyle and live as normal as possible. They just wanted to keep going. There is a need for a different approach to communicating with MI patients at the time of discharge. Person-centred care that allows personal narratives to emerge may enable health-care professionals to offer more individualised guidance to MI patients that will help them cope with the everyday challenges they experience after discharge. © The European Society of Cardiology 2015.

Lessons on aging: Hopes and concerns of Japanese women at midlife.

2016-01-01

Japan is leading the global trend of decreasing birth rates and the graying of society. In this study we examine women's changing gender and intergenerational relationships and how these affect their concerns and hopes for their futures. Many of the 121 midlife women (aged 45-55) interviewed viewed themselves as sandwiched between their mothers-in-law and actual or potential daughters-in-law, at the nadir of intergenerational status within their families, in large part due to changing social patterns in marriage and birth rates. Doubts about the marriageability of their sons arising from role expectations for brides to care for parents-in-law cause concern for many and highlight the gendered and intergenerational nature of aging concerns. Yet, midlife in the 21st century, with changing gender and intergenerational roles, appears to create opportunities for many Japanese women to reflect on the meaning of the next stage of their lives. Changing gender and intergenerational relationships may contribute to their hopes to live a life of self-actualization and to be true to one's self (jibun rashiku ikiru).

Community-Based Decision-Making: Application of Web ...

EPA Pesticide Factsheets

Living, working, and going to school near roadways has been associated with a number of adverse health effects, including asthma exacerbation, cardiovascular impairment, and respiratory symptoms. In the United States, 30% - 45% of urban populations live or work in the near-road environment, with a greater percentage of minority and low-income residents living in areas with highly- trafficked roadways. Near-road studies typically use surrogates of exposure to evaluate potential causality of health effects, including proximity, traffic counts, or total length of roads within a given radius. In contrast, simplified models provide an opportunity to examine how changes in input parameters, such as vehicle counts or speeds, can affect air quality. Simplified or reduced-form models typically retain the same or similar algorithms most responsible for characterizing uncertainty in more sophisticated models. The Community Line Source modeling system (C-LINE) allows users to explore what-if scenarios such as increases in diesel trucks or total traffic; examine hot spot conditions and areas for further study; determine ideal monitor placement locations; or evaluate air quality changes due to traffic re-routing. This presentation describes the input parameters, analytical procedures, visualization routines, and software considerations for C-LINE, and an example application for Newport News, Virginia. Results include scenarios related to port development and resulting traffic

Interprofessional Education Perceptions of Dental Assisting and Radiologic Technology Students Following a Live Patient Experience.

PubMed

Reddington, Amanda R; Egli, Amy J; Schmuck, Heather M

2018-05-01

Health professions students are often unaware of other health care providers' roles or professional expertise due to most education taking place within their single profession. This pattern may be even more prevalent for baccalaureate and associate degree programs since most interprofessional education (IPE) occurs in predoctoral programs and, when IPE is incorporated into allied health professions education, it often utilizes simulation instead of live patient experiences. The aim of this study was to determine if radiologic technology and dental assisting students' perceptions changed regarding interprofessional practice and teamwork after an IPE activity with actual patients. The participants were students in the University of Southern Indiana (USI) radiologic technology and dental assisting programs. This mixed-methods pilot study conducted in 2017 collected quantitative and qualitative data from pre and post surveys, the researchers' observations of student interactions during live patient assessment and acquisition of panoramic images, and large-group discussion. Twenty-five of the 26 students who participated in the IPE program completed both pre and post surveys, for a 96% response rate. The results showed significant differences in the participants' perceptions from the pre to post surveys on a wide variety of survey items. Most notable were the positive changes in perceptions related to trust in judgment of others within their profession (p=0.001), relationships with other professions (p=0.002), and thinking highly of other professions (p=0.002). Overall, this study found that incorporating the IPE activity with a live patient into these radiologic technology and dental assisting programs improved the students' perceptions of other allied health professionals. Future research should include more participants to increase sample size and add quantitative data collection.

Lived experiences of breast cancer survivors after diagnosis, treatment and beyond: qualitative study.

Williams, Faustine; Jeanetta, Stephen C

2016-06-01

The number of breast cancer survivors has increased since 1990 due to advances in biomedical technology that lead to an increase in early diagnosis and treatment. Research on survivorship has focused on the psychological and treatment aspects of the disease. The goal of this study was focused on exploring the lived experiences of breast cancer survivors from diagnosis, treatment and beyond. To understand the lived experiences of women who are breast cancer survivors. A purposive sampling strategy was used to recruit participants from two Missouri cancer centres. A total of 15 women breast cancer survivors were interviewed. Three major themes emerged that described the lived experiences of the women. These were factors from the diagnosis and treatment management impacting survivorship, relationship and support system and implication of survivorship. Participants noted that coping with the diagnosis and treatment was a stressful journey and required lots of adjustment and changes. Some developed various techniques such as journaling their activities which provided comfort. In addition, support from family was shared as the key which gave them strength and courage through the different stages of treatment. However, they found it difficult to articulate what survivorship meant. Using in-depth interview techniques, this study shed light on the experiences of women who were diagnosed with breast cancer and have completed treatment. They acknowledged frustration with their diagnosis and body changes. Support received from family and friends helped them cope through their treatment. However, they felt abandoned once the treatment phase was over and were uncertain what survivorhood meant to them. © 2015 The Authors Health Expectations Published by John Wiley & Sons Ltd.

People with advanced cancer experience bodily change resulting in debilitating functional decline. Although inability to participate in everyday activities (occupation) contributes to profound suffering, limited research has examined the relationship between altered bodily experience (embodiment) and functional ability. The purpose of this study was to better understand the lived experience of functional decline for people with advanced cancer living at home. Indepth interviews were conducted with 10 community dwelling people with advanced cancer about their bodily experiences of functional decline. This study employed a pragmatic qualitative approach, informed by hermeneutic phenomenology. People described living with rapidly disintegrating bodies and how this affected their ability to participate in everyday activities. Analysis identified themes which were evaluated against conceptual frameworks of 'occupation' and 'embodiment'. People experienced a shifting sense of self. They had to continuously reinterpret changing bodies. Previously automatic movements became disjointed and effortful. Simple actions like standing or getting out of bed required increasing concentration. Relentless bodily breakdown disrupted peoples' relationship with time, hindering their ability, but not their desire, to participate in everyday activities. Contending with this deterioration is the work of adaptation to functional decline at the end-of-life. This study highlights the role active participation in everyday activities plays in mediating adjustment to functional decline. These findings challenge us to look beyond palliation of physical symptoms and psychospiritual care as ends in themselves. Symptom control and palliation should be viewed as mechanisms to optimise active participation in essential and valued activities. Published by the BMJ Publishing Group Limited.

Background Sexually transmitted infections (STI) have made a resurgence in many rapidly developing regions of southern China, but there is little understanding of the social changes that contribute to this spatial distribution of STI. This study examines county-level socio-demographic characteristics associated with syphilis and gonorrhea in Guangdong Province. Methods/Principal Findings This study uses linear regression and spatial lag regression to determine county-level (n = 97) socio-demographic characteristics associated with a greater burden of syphilis, gonorrhea, and a combined syphilis/gonorrhea index. Data were obtained from the 2005 China Population Census and published public health data. A range of socio-demographic variables including gross domestic product, the Gender Empowerment Measure, standard of living, education level, migrant population and employment are examined. Reported syphilis and gonorrhea cases are disproportionately clustered in the Pearl River Delta, the central region of Guangdong Province. A higher fraction of employed men among the adult population, higher fraction of divorced men among the adult population, and higher standard of living (based on water availability and people per room) are significantly associated with higher STI cases across all three models. Gross domestic product and gender inequality measures are not significant predictors of reported STI in these models. Conclusions/Significance Although many ecological studies of STIs have found poverty to be associated with higher reported STI, this analysis found a greater number of reported syphilis cases in counties with a higher standard of living. Spatially targeted syphilis screening measures in regions with a higher standard of living may facilitate successful control efforts. This analysis also reinforces the importance of changing male sexual behaviors as part of a comprehensive response to syphilis control in China. PMID:21573127

The major changes to our world are those involving the atmosphere and the climate, including global warming induced by anthropogenic factors, with impact on the biosphere and human environment. Studies on the effects of climate changes on respiratory allergy are still lacking and current knowledge is provided by epidemiological and experimental studies on the relationship between allergic respiratory diseases, asthma and environmental factors, like meteorological variables, airborne allergens and air pollution. Epidemiologic studies have demonstrated that urbanization, high levels of vehicle emissions and westernized lifestyle are correlated with an increased frequency of respiratory allergy, mainly in people who live in urban areas in comparison with people living in rural areas. However, it is not easy to evaluate the impact of climate changes and air pollution on the prevalence of asthma in general and on the timing of asthma exacerbations, although the global rise in asthma prevalence and severity could be also considered an effect of air pollution and climate changes. Since airborne allergens and air pollutants are frequently increased contemporaneously in the atmosphere, enhanced IgE-mediated response to aeroallergens and enhanced airway inflammation could account for the increasing frequency of respiratory allergy and asthma in atopic subjects in the last five decades. Pollen allergy is frequently used to study the interrelationship between air pollution and respiratory allergic diseases such as rhinitis and bronchial asthma. Climatic factors (temperature, wind speed, humidity, thunderstorms, etc) can affect both components (biological and chemical) of this interaction. Scientific societies should be involved in advocacy activities, such as those realized by the Global Alliance against chronic Respiratory Diseases (GARD).

Coral reefs, and the unique ecosystems they support, are facing severe threats by human activities and climate change. Our understanding of these threats is hampered by the lack of robust approaches for studying the micro-scale interactions between corals and their environment. Here we present an experimental platform, coral-on-a-chip, combining micropropagation and microfluidics to allow direct microscopic study of live coral polyps. The small and transparent coral micropropagates are ideally suited for live-imaging microscopy, while the microfluidic platform facilitates long-term visualization under controlled environmental conditions. We demonstrate the usefulness of this approach by imaging coral micropropagates at previously unattainable spatio-temporal resolutions, providing new insights into several micro-scale processes including coral calcification, coral–pathogen interaction and the loss of algal symbionts (coral bleaching). Coral-on-a-chip thus provides a powerful method for studying coral physiology in vivo at the micro-scale, opening new vistas in coral biology. PMID:26940983

Children's voices: living with HIV.

Mawn, Barbara Ellen

2011-01-01

To present the findings from a qualitative study that explored living with pediatric HIV from the children's perspectives. The researcher conducted face-to-face interviews with seven HIV-positive children in this nested, phenomenological study. The children's parents were enrolled at the same time in a longitudinal qualitative study, which focused on raising a child with HIV. The children, ages 9 to 13, were interviewed once in the context of their homes. The researcher identified themes based on interview transcriptions. Four major themes emerged: a positive self-perception; varying levels of understanding about HIV; a lack of concern and/or memory about the disclosure process; and an awareness to keep the diagnosis private. Nurses who counsel children living with HIV should be aware that the self-perception of these children varies and may not be focused on their chronic illness. The interpretation of the disclosure process and the understanding of the diagnosis itself may be impacted by memory and developmental changes over time.

Objective Some studies have assessed the effectiveness of environmental interventions to promote physical activity, but few have examined how such interventions work. We investigated the environmental mechanisms linking an infrastructural intervention with behaviour change. Design Natural experimental study. Setting Three UK municipalities (Southampton, Cardiff and Kenilworth). Participants Adults living within 5 km of new walking and cycling infrastructure. Intervention Construction or improvement of walking and cycling routes. Exposure to the intervention was defined in terms of residential proximity. Outcome measures Questionnaires at baseline and 2-year follow-up assessed perceptions of the supportiveness of the environment, use of the new infrastructure, and walking and cycling behaviours. Analysis proceeded via factor analysis of perceptions of the physical environment (step 1) and regression analysis to identify plausible pathways involving physical and social environmental mediators and refine the intervention theory (step 2) to a final path analysis to test the model (step 3). Results Participants who lived near and used the new routes reported improvements in their perceptions of provision and safety. However, path analysis (step 3, n=967) showed that the effects of the intervention on changes in time spent walking and cycling were largely (90%) explained by a simple causal pathway involving use of the new routes, and other pathways involving changes in environmental cognitions explained only a small proportion of the effect. Conclusions Physical improvement of the environment itself was the key to the effectiveness of the intervention, and seeking to change people's perceptions may be of limited value. Studies of how interventions lead to population behaviour change should complement those concerned with estimating their effects in supporting valid causal inference. PMID:26338837

Family structure change can disrupt the settings of children’s daily lives. Most scholarship focuses on disruption in the home environment. Moving beyond the home, this study explores the association between changes in family structure and changes in several dimensions of early child care. With longitudinal data from the NICHD Study of Early Child Care and Youth Development (n = 1,298), first-difference models reveal that family structure transitions are associated with changes in the type and quantity of early care as well as the number of care arrangements used, especially during the latter part of infancy. Given prior evidence linking these child care dimensions to behavioral and cognitive outcomes, these results suggest a policy-relevant mechanism by which family change may create inequalities among children.

This article aims to provide an insight into play as an important aspect of children’s lives in an under-studied area of Iran. Our observations focus on the province of Kohgilouyeh and Boyer Ahmad with its ancient nomadic cultures. Through first-hand knowledge and lived experiences, supplemented by available literature, we seek to look at children’s games in the frame of culture change, exploring their relationship with children’s health and wellbeing. Play, as in every region in the world, conveys and reflects the dominant culture and teaches the values of the society in which the children live in the here and now and in which they will have to function as adults. Yet, types of play are not static. They develop alongside social, political and economic changes and embrace new forms emerging from modern lifestyles. The latter sometimes come into conflict with and challenge the local culture and traditional types of play, which are based on the lives and histories of the indigenous peoples and local communities. A sample of traditional tribal forms of play is analyzed for their health, entertainment and fun aspects. Such play allows children to prepare for life’s realities, in particular for a life of cooperation. By contrast, whilst also providing children with tools and skills for the needs of modern life, new types of play focus more on competition and individualism. This divergence expressed in different types of play widens the generation gap and contributes to alienation. The shift from a collective to individualistic lifestyle thus has an unsettling impact on the community and impacts on the emotional and physical wellbeing of children. We will describe types of play and their role in the holistic development of nomadic children, as well as the impact of modernization and social change, including sedentarization. The article will highlight some consequences of the demise of indigenous play, through observation and analytical comparison of children’s play in three generations. Based on the insights gained, the authors offer recommendations on how to restore traditional play and games through redesigning them to be capable of adaptation to changes in lifestyles.

A limited amount of research has examined the effect of changing public open spaces on active living. This paper will present the study protocol of a community-based intervention study co-designed in an interdisciplinary collaboration with community members to develop urban installations highly tailored to promote active living among children (10-13-years-old) and seniors (>60-years-old) in a deprived neighbourhood in Copenhagen. The study builds on a quasi-experimental study design with two sub-studies: 1) a children study and 2) a senior study. The interventions will be developed, designed and implemented in collaboration with local children and seniors, respectively, using different co-design tools and methods. We will evaluate the effect of the interventions on children's and senior's use of the new-built urban installations using accelerometers in combination with GPS as well as systematic observation using the System for Observing Play and Recreation in Communities (SOPARC). A process evaluation with focus groups consisting of the various stakeholders in the two sub-studies will be used to gain knowledge of the intervention processes. The paper presents new approaches in the field of public open space interventions through interdisciplinary collaboration, participatory co-design approach and combination of measurements. Using both effect and process evaluations the study will provide unique insights in the role and importance of the interdisciplinary collaboration, participatory processes, and tailoring changes in public open space to local needs and wishes. These results can be used to guide urban renewal projects in deprived neighbourhoods in the future. Retrospectively registered with study ID ISRCTN50036837 . Date of registration: 16 December 2016.

Background We sought to study the impact of the change in gender balance and the shift in generational beliefs on the practice of surgery. Methods We used in-depth, individual, semistructured interviews to explore the ideas, perceptions and experiences of recently recruited academic surgeons regarding the role of gender and the influence of the changing attitudes of this generation on the work environment. All the interviews were audiotaped and transcribed verbatim. The data analysis was both iterative and interpretative. Results Nine women and 8 men participated in the study. All participants stated that departmental expectations regarding their performance as clinicians and as academics were not influenced by gender. However, further exploration revealed how gender did influence the way they sought to balance their personal and professional lives. Women in particular struggled with attaining this balance. While maternity leave was endorsed by both men and women, the challenging logistics associated with such leave were noted. Our data also revealed a generational shift among men and women in terms of the importance of the balance between their personal and professional lives. Participants saw this priority as radically different from that of their senior colleagues. Conclusion Gender and the shift in generational attitudes are changing the culture of academic surgery, often described as the prototypical male-dominated medical environment. These changes may reflect the changing face of medicine. PMID:23484466

To describe changes in oral health-related quality of life and to evaluate the associations of these changes in community-dwelling older people. In this longitudinal study a representative sample of 872 older people, living in Brazil, was evaluated during 2004. The follow-up was carried out during 2008, with 587 older persons evaluated. A questionnaire assessing socio-demographic information, health history, oral health-impact profile and number of natural teeth was used. Changes in oral health-related quality of life were categorized as improvement or deterioration. Data analysis was performed using a hierarchical approach based in a conceptual framework. A hierarchal approach was carried out using Poisson regressions. Older persons living in rural areas, those who reported brushing once a day or less and older persons with fewer natural teeth had an increased chance of reporting deterioration in oral health-related quality of life. Women and participants who received a minimum wage of less than US $219.50 were more likely to report improvement in oral health-related quality of life. The results of this study suggest that changes in the oral health-related quality of life are influenced by many of the variables that were included in the conceptual framework. © 2012 John Wiley & Sons A/S and The Gerodontology Society.

Although there is a significant body of literature addressing heart failure (HF) epidemiology, physiology, and treatment, little is known about the experiences of Thai patients living with this chronic condition. The primary goal of this study was to gain a better understanding of how Thai patients with HF live with chronic and debilitating illness. A phenomenological approach was chosen to investigate the experience of living with HF. Fifteen Thai men and women with HF in New York Heart Association classes I to III, aged between 47 and 75 years, were interviewed with open-ended questions. Data were analyzed using qualitative inductive content analysis. Three themes emerged from the data analysis: identifying losses or changes in their lives, accepting the losses, and regaining some control. Unlike their western counterparts, the Thai patients with HF incorporated their karma, a Buddhist belief system, as a tool to rationalize the occurrence of their HF experience. The participants of this study used kreng jai as a cultural desire not to disrupt the happiness of others, even at the expense of efficiency, or to burden others, which might affect their own quality of life. The Thai patients with HF faced many limitations. The Thai patients with HF use religion and traditional culture to overcome their life situations. To support Thai patients with HF, healthcare providers must have an understanding of cultural differences.

Our objective in this study was to examine how family social-support expectations have changed among older Chinese and Korean U.S. immigrants. Fifty-two Cantonese- and Korean-speaking immigrants older than 60 years participated in eight focus groups. Transcripts were translated into English. Themes were developed based on a coding structure and compared to past research. Participants discussed changed perspectives of family social support and the need to integrate both American and Chinese or Korean culture, thus becoming bicultural. Three distinct perspectives of family emerged: (1) participants felt they had become peripheral family members, (2) parents were no longer authority figures in families, and (3) participants were more independent. Finally, participants described how factors such as a changed economic environment, living alone, and extending their social network beyond family, promoted a move to biculturalism. These results suggest that the integration of two cultures, or biculturalism, is an indicator of successful adaptation to immigration later in life; older Chinese and Korean immigrants are adjusting to living in the United States and blending multiple cultures simultaneously. Thus, acculturation frameworks implying a linear process may not be theoretically valid as ethnic identity, particularly for those who immigrate to different countries, changes over the life course.

To examine factors associated with changes in mobility and living arrangements in a comprehensive geriatric outpatient assessment after hip fracture. Population-based prospective data on 887 consecutive hip fracture patients aged 65 years and older. The domains of the geriatric assessment were the independent and changes in mobility level and living arrangements 4 months postoperatively the outcome variables. Of the survivors, 499 (73%) attended the assessment. The mobility level had declined in 39% of the attendees and 38% of them had moved to more supported living arrangements 4 months after the hip fracture. In the age-adjusted univariate logistic regression analyses, almost all the domains of the comprehensive geriatric assessment were significantly associated with both outcomes. In the forward stepwise multivariate analysis, disability in activities of daily living, poor performance in Timed Up and Go and comorbidity as measured by the American Society of Anesthesiologists scores remained significantly associated with the outcomes. While comorbidity and disability in activities of daily living and mobility are the major indicators of poor outcomes of mobility and living arrangements after hip fracture, all the domains in the comprehensive geriatric assessment deserve attention during hip fracture care and rehabilitation. In almost half of the patients the mobility level and living arrangements had deteriorated 4 months after the hip fracture, suggesting an urgent need for more effective postoperative rehabilitation. Almost all the domains of the comprehensive geriatric assessment were associated with poor outcomes and require equal attention during the acute and postacute phases of hip fracture care and in the course of rehabilitation. A geriatric outpatient assessment a few months after the hip fracture provides a check-point for the outcomes and an opportunity to target interventions at different domains of the comprehensive assessment.
